Abstract Meconium stained amniotic fluid (MSF) is a leading cause of neonatal mortality and morbidity. The aim of this study was to assess the association of umbilical cord vessels’ PH with pregnancies complicated by meconium stained amniotic fluid. This cross sectional study was conducted among 195 pregnant women. The umbilical cord blood samples of 96 neonates (52 neonates with normal vaginal delivery (NVD) and 44 with cesarean section (C/S)) with MSF and of 99 neonates (49 neonates with NVD and 50 with C/S) with clear amniotic fluid were collected. DemograpHic data (age, gestational age), antenatal characteristics (duration of labor, active pHase and second stage of labor, duration of induction, type of anesthesia), postnatal characteristics (Apgar score at 1 and 5 min) was documented for each patient. Women with preterm labor or other pregnancy related diseases (hypertension, preeclampsia, gestational diabetes mellitus, prolonged rupture of membrane) and multifetus pregnancies were excluded. Data was analyzed using SPSS (V.18) by statistical tests (independent T-test, chi – square, ANOVA). P-value below 0.05 considered statistically significant. The mean age of participants was 26.8 ± 5.4. The mean PH value in all participants was 7.26± 0.07. There was no significant difference between the two groups (case and control) for PH (p > 0.05). The results showed that, duration of active pHase of labor, Apgar score at 1 min and the number of pregnancies had significant correlation with umbilical cord PH (P < 0.05). There was no significant relation between umbilical cord PH and duration of labor and second stage of labor, meconium concentration, type of anesthesia, duration of induction (p > 0.05). The mean umbilical cord PH among patients with meconium stained amniotic fluid was higher in neonates born thorough cesarean section. Apgar score at 1 min was related to umbilical cord PH.

Abstract: One of the solutions for the security of the systems and computer networks is the formation of intrusion detection systems. In the design of these systems, the techniques of artificial intelligence such as neural network, data mining techniques, expert systems, genetic algorithms and fuzzy systems are applied. The main aim is the design of the system that besides exact detection is with low error. The main aim of detection in these systems is their analyzer. It seems that if the input of analyzer of the systems is language variables and final detection is done as fuzzy inference, the results of the analysis get better and an exact detection is done. In addition to reduction of error, it can present good information in the form of fuzzy rules to the security expert of the system. Genetic algorithms by flexible and prevalent searching ability can be applied for optimized learning of fuzzy system rule base. The current paper aimed to evaluate, design and implement fuzzy genetic intrusion detection system. The experiments and the results showed the considerable effect of using the proposed architecture on the improvement of detection.

Abstract: The aim of this study is to assess aerobic, anaerobic and performance indexes changes after a short period of coenzyme Q10 Supplementation in soccer players. 16 soccer players (Weight 57.1±20.72, height 171.4±4.92, and age 22.30±1.41) randomized and divided into two groups. Where supplement group (N=10) consumed CoQ10 supplement (300 mg/day) and placebo group (n=6) consumed placebo. Both of them practiced for 4 weeks and each one 90 minutes. After that, supplement group started to consume CoQ10 in amount of 300 mg/day for one month. Findings has been showed that 4-week supplement consumption caused significant changes in VO2max and performance in soccer players, while this intervention did not result in significant effect in body composition, maximum running speed, peak anaerobic power and fatigue index. The major findings of the present study were that 4-week of CoQ10 supplement consumption in college soccer players led to increase aerobic power and performance in high intensity aerobic interval test. From the other point of view, these variations were not significant in placebo group. We can conclude that although increase in maximum running speed (vVO2max) was not significant, four weeks of CoQ10 supplement consumption may increase in maximal oxygen consumption and performance in college soccer players. Finally, in this case consumption of this supplement could improve player’s performance in competition conditions.

Abstract: Although worldwide prevention and community information about AIDS has been developed in recent decades, it is still considered as a problem for public health. Dental students are at increased risk for HIV infection because of overutilization and unsafe injections during surgery or other procedures. Knowledge of dental students about HIV infection and its transmission ways is an important subject in health care system. The purpose of current study was to evaluate knowledge of dental students of Hormozgan University of Medical Sciences. This was a cross sectional study carried out among all of the dental students of Hormozgan University of Medical Sciences (HUMS) in 2012-2013. A questionnaire containing demographic question (age, gender) and 20 questions (7 general questions and 13 specialized questions) about knowledge toward HIV/AIDS was distributed among the participants. Data was analyzed by frequency, one way t-test, chi-square and spearman correlation test using the SPSS (V.19). The significant level was set as < 0.05. Totally 78 student participated in this study. The mean age of participants was 21.44 ± 2.54. Forty five (57.7%) were preclinical students. The mean score of questionnaires was 52.38 ± 4. This score among preclinical students was 52.28 ± 4.2 and in clinical students was 52.92 ± 3.4.There was no significant difference between total scores of respondents among clinical and preclinical students (P > 0.05). Only two students (2.5%) got below 41 points (poor knowledge). Fifteen students had achieved between 41 to 50 points (moderate knowledge) and the remains (N = 61, p = 78.2%) achieved higher than 51 points (good knowledge). Although, the knowledge of dental students was high, they didn’t have enough knowledge about post exposure prophylaxis which is an important subject and any oral health worker may experience it in their professional life. Educating health care workers especially dental students regarding the prophylaxis strategies in preclinical course is recommended.

Abstract: In this research mechanochemical resuscitation of the copper oxide by the Zinc in order to make Nano-structured composite Brass and enhanced solubility limit on the Zinc lattice has been survived. Ball milling on a mixture of the Copper oxide and the Zinc powder to produce the alloy Brass with 35 and 50 atomic percent of the Zink was conducted. XRD results indicated that ball milling a mixture of the Zinc and the Copper oxide with molar ratio 1 to 1 for about 45 minutes can lead to fully reclamation of the Copper oxide and ball milling with Zink molar ratio for 5 hours can lead to make the alloy Brass. The Zinc oxide particles as a reinforcing phase are dispensed with same distribution. By increasing atomic percentage of the Copper to 65, lattice parameter of the allay Brass has fallen. It represents dissolution of zinc on the Brass lattice α+ β and makes a super-saturated solution of the Brass from proportions of the zinc and the copper.

Abstract: In this paper a method for modeling integrator and derivative of effort and flow variables in a bond graph model is offered. In many dynamical systems there is a need to get the value of integral and derivative of a variable, for example in PID controller in a closed-loop controlled system. Here the way of implementing individual integrator and derivative elements using bond graph possibilities is presented. In this work the variables that their integral or derivative values are taken, are presented in the form of effort or flow variables as two fundamental variables of the system. This will allow us to model many systems by bond graph that they couldn’t be modeled before. In continue, its usage in some examples is presented. For examples classic closed-loop controlled systems by PID controller are used. Then the state equations, ruled over the full closed-loop system, are extracted from the model. It can be seen that the PID gains are appeared in the state equations. This specification is used in adaptive control by gain scheduling approach, and by these equations; the PID gains, required for attaining the desired system behavior along the time, are obtained. Using this method the PID gains for gain scheduling approach for a nonlinear plant can be obtained with no need to linearizing it. Furthermore this approach has the advantage of capability of modeling hybrid systems consist of various domains such as mechanical, electrical, hydraulic, magnetic and …, and designing controller for them. It can be seen that in this paper there are some novelties consist of modeling integrator of effort and flow by bond graph, modeling closed-loop controlled systems entirely by bond graph and also investigating adaptive control by bond graph.

Abstract: Existing evidence about the indicators of board performance evaluation in the healthcare organizations demonstrated that a comprehensive review of literature is still required to broaden our understanding of this topic. This review aimed to add to the literature on performance evaluation of the boards by providing a summary of literature-based perspectives. Using a systematic search strategy, ten eligible papers were entered into the review. Thirty-five indicators of board performance evaluation in the healthcare organizations were identified in these papers. We illustrated more about these indicators in the paper. Our results showed a gap in the literature with respect to the performance evaluation of the health boards. Given the unique context of the health organizations, it is suggested that more research need to be done in order to understand the indicators of the board performance evaluation.

Abstract: This study aims to determine the digestive effect of garlic (Allium sativum L.) on acid secretion and stomach pepsin. In this study two groups of 12 wistar rats were tracheostomized, laparatomized, gastrodeodonostomized, and then 100mg/kg of garlic methanol extract dissolved in 9% saline was introduced into their stomach. The stomach secretions then washed out in first base, second base, vagus-stimulated conditions and reverse to base. The vagus nerves of both side of the neck released from carotid sheet and stimulated with 15 millivolts, frequency of 4 Hz and 1 millisecond wide. The gastric acid amounts were measured by titrometry and gastric pepsin amounts were measured by Anson technique. The study showed that garlic extract increased the level of acid secretion in all stages and pepsin secretion in first base, vagus stimulated conditions, and reverse to base significantly compared to the control group (P<0.05). The vagus-stimulated conditions caused a significant increase in gastric acid and pepsin secreting compared to the first base (P<0.05). The level of gastric acid and pepsin secretion did not show a relationship between the rats and their gender. In conclusion using this plant and its other products is forbidden for those patients suffering from indigestion due to acid or pepsin increase. So patients suffering from gastritis, duodecimal and ulcer are not allowed to use this plant in their daily diet.

Abstract: Hexapod Robots gives us the ability to study walking robots without facing problems such as stability in many aspects. It has a great deal of flexibility in movement even if a leg becomes malfunctioned. Radially symmetric (hexagonal) hexapods have more flexibility in movement than rectangular leg alignments. Because of symmetry they can move in any direction and time efficiently. Inverse kinematic problem of this kind of hexapods is solved through a modular mobile view considering six degrees of freedom for the trunk. Then typical tripod and wave gaits are analyzed and simulated through the presented formulation. In Reinforcement Learning algorithm for walking it is important how to make reward signal with respect to robot’s actions and states. A fuzzy approach is presented and analyzed to generate reward signals. It is shown that the presented fuzzy system generates more considerable accurate rewards with better performance than functional rewards which are used in walking learning problems.

Abstract: Worldwide Interoperability of Microwave Access (WiMAX) has potential success in its line-of-sight (LOS) and non line-of-sight (NLOS) conditions which operating below 11 GHz frequency. There are going to be a surge all over the world for the deployment of WiMAX networks. Estimation of path loss is very important in initial deployment of wireless network and cell planning. The wireless channel is modeled as a sum of paths. The wireless channel is modeled as a sum of paths. When the paths represent reflections, the path-strengths depend on the distances traveled and on the reflection coefficients.

Abstract: Mechanical Activation Assisted Self-Propagating High-Temperature Synthesis (MASHS), as an advanced method in early decades is used for synthesis of advanced engineering compounds and composites; so, preparation of ceramic composites reinforced by second phase by this process is focused in different industries because of their unique thermal, erosion, corrosion, chemical, mechanical and electrical properties. In this research the influences of type and pressure of synthesis environment and preheating of samples on synthesis characteristics and structure of produced ZrB2-ZrC composite were surveyed. Raw materials powder were mixed stoichiometrically and ball milled for 10 hours according to 2ZrO2+B2O3+C+7Mg=ZrB2+ZrC+7MgO chemical equation. Then influences of type and atmosphere of synthesis environments including relative vacuum, Argon gas in atmospheric pressure and pressurized Argon gas and also preheating of samples conditions on combustion reaction, synthesized phases and achieved product structure were studied. Synthesized samples were analyzed by XRD and SEM methods for inspecting of produced phases and achieved structures. XRD patterns revealed that by changing combustion environment from relative vacuum to pressurized atmosphere, process is more controllable for producing desirable phases but from structural point of view, only preheated sample was synthesized in the form of nanocomposite.

Abstract: Apples are one of the oldest fruits known to mankind and have been cultivated for many years. In order to investigate the effect of foliar application of amino calcium on Golden Delicious apple trees a randomized complete block design with four repetitions was conducted in the city Abadeh, Fars Province, southern Iran. Apple trees were sprayed with different concentrations (0, 2.5, 5.0, and 7.5 mg/l) of amino calcium. After spraying the trees mature fruits were harvested and stored in cold storage houses for 3 months. After this period, traits such as amount of calcium, fruit weight, fruit firmness, and decay were assessed at the horticultural laboratory of Jahrom Azad University. We found that foliar application of amino calcium delayed and decreased the amount of fruit decay during storage. Fruit firmness was highest in apples that were sprayed with 7.5 mg/l amino calcium. Moreover, fruits that were sprayed with 7.5 and 5 mg/l amino calcium had lower weight reduction compared with fruits that were sprayed with other concentrations of amino calcium. We found no significant difference between different concentrations of amino calcium with respect to calcium levels.

Abstract In order to investigate the effect of foliar application of chelated calcium on Red Delicious apple trees, a randomized complete block design with four repetitions was conducted in the city Abadeh, Fars Province, southern Iran. In this experiment, different concentrations (zero, 2.5, 5.0, and 7.5 mg/l) of calcium chelate were sprayed on the apple trees. After spraying the trees, mature fruits were harvested and kept in the cold house for 3 months. After this period, traits such as TSS percentage, fruit weight, fruit firmness and decay of tissue were assessed at the horticultural laboratory of Jahrom Azad University. The results showed that the percentage of fruit decay in the control treatment was more than the other treatments. The foliar application of calcium chelate on apple trees considerably reduced fruit decay during storage. The highest fruit firmness was related to apples that were sprayed with chelated calcium at concentrations of 0.5 and 7.5 mg/l. Moreover, the fruits sprayed with the control treatment had the highest percentage of weight loss. Spraying fruit trees with chelated calcium led to less weight loss during storage. The highest TSS percentage was related to apples treated with 7.5 mg/l chelated calcium.

Abstract: In this study geological-reservoir zonation has been developed based on petrophysical logs and then petrophysical parameters such as porosity, Water saturation and NTG have been determined, evaluated and distributed throughout of the field. Ilam Formation is subdivided into three zones and two subzones. This zonation has been extended and correlated to 4 nearby oil fields. In order to populate the petrophysical properties into the reservoir, structural model and 3-D geocellular grid of the field has been constructed using required geological and geophysical data. Each zone includes some layers depending on the petrophysical/lithological heterogeneity. Based on porosity and water saturation distribution, 2 rock types including a good rock with a connate water saturation of 25% and poor rock type with a connate water saturation of 50% have been determined. Water saturation cut off has been determined upon to modality of water saturation distribution plot and based on intercept of 2 groups of sw frequencies, porosity cut off was defined. PHIE=2% and Sw=76% have been identified as cutoff criteria for NTG. Petrophysical modeling has been carried out using deterministic approach. Trend maps indicate that, PHIE parameter decreases from western toward eastern of the field, in all zones.

Abstract: Bamdej Wetland with approximate area of 4000 hectare in longitude of 48˚ E and latitude of 31˚N is situated in southern west of Iran and 40 kilometer distance from northern west of Ahvaz which is bordering Shavoor dam and Village farms in north, Tavana channel in South, bamdej village alongside Ahvaz-Andimeshk railway in east and Sadat Tavaher and Sayed Jasem villages in west. Shavoor Dam is in the river path of Shavoor which upon crossing divided into two branches, Nahr lashkar and Nahr khavoor. The aquatic habitat of it which constitutes the main part of wetland has provided appropriate and secure place to scatter the regional animals particularly local and oviparous birds due to dominant plants like cane and bulrush. Some parts among the wetland are without the above coverage and it constitutes an aquatic open place which is the proper place for feeding and resting aquatic animals especially birds of passage. This research with the aim of ecological evaluation in order to call Bamdej Wetland as conservation place has been accomplished by using amended model of Canada Environment Organization and rapid assessment; consequently through two models, Bamdej Wetland achieved title of conservation region.

Abstract: In bending buildings with large openings, using beams as load bearing trusses is going to be regarded as one of the main design choices due to the economic characteristics as well as being simple to connect to the columns, being lighter, open truss webs making better use of space providing better facilities for passing pipes, which results in stories with lower heights. Besides these advantages, these structures have important disadvantages. Due to the way of building, the beams have more hardness and resistance than columns. In such structures under earthquake, there is the possibility of formation of plastic hinge in columns, which is not good according to engineers. Also, due to premature buckling of the web members under horizontal reciprocating loads, a sharp drop in the hysteresis graph of these systems is observed which indicates a very low energy absorption in these systems and the hysteresis graph of these systems is unstable. Recently a new type of truss is proposed in which the plastic hinge location is in the central part of truss and also their hysteresis graphs are more stable, these frames are namedspecial truss moment frames”. And also The different behavior of structures and heavy losses in four quakes; Northridge1994 (California),Kobe 1995) Japan, Duzce (1999) Turkey, Chi-Chi (1999) Taiwan, especially in the structures located on the path leading to the rupture, has made clearly evident the significance of paying utmost attention to the near-fault records. This study was designed to compare the seismic behavior of special truss moment frames at near-fault and far-fault points. For this purpose, a non-linear static analysis method and non-linear dynamic time history is used. 1, 3 and 5 storey structures, designed using Iran’s 2800 code and ubc97, have been studied in this research. Plastic hinges are considered for these structures according to FEMA-356 Criteria and selected records (Two horizontal components and a vertical component) are based on the soil type and the scale is 5% damping. Analysis was performed using the program Sap2000 for all three structures.

Abstract: Sunlight is a clean energy source taking advantages of which increasingly rises all over the world. But, constructing solar power plants incurs huge amounts of costs on the states. Therefore, designation and production of appliances which their energies are supplied from the sun can be an appropriate alternative to diffuse a solar power plant in the people homes. Thus, construction, implementation and maintenance costs are incurred to the public. By the way, solar washing machine production idea was formed. This washing machine of logic fuzzy type can wash 5kg of clothes once in three days without any requirements for electricity. Green color on its LCD indicates full charge batteries and also these data are recognizable on a smart phone. Energy stored in washing machine feed can be used to turn on other facilities at home. For example, there are any possibilities to turn on mixer, toaster or even cell phone and lap top. In the events of power outage, the building can operate as an independent energy source and guarantee home lighting for more 20 hours. Just with the production of 200,000 solar washing machines more than 10,000Mw can be annularly saved. This innovation has been recorded in Patent No. 63594 in Patent and Trademark Office.

Abstract: This paper proceeds numerical investigation on forced convective heat transfer of nanofluids in laminar flow inside a mini-channel with circular cross-section under constant heat flux boundary condition at walls. Nanofluid contains CuO nanoparticles with diameter of 50 nanometer in water base fluid. At the entrance of channel, profiles of uniform velocity & temperature prevail. In order to obtain fully developed profiles, geometry of problem considers as L/D = 100. Problem is solved by means of 4 different models, including Homogeneous and Dispersion models in both of constant and variable thermophysical properties through the finite-volume method. The temperature-dependent properties was used for the first time in nanofluids dispersion model. It was regarded in the presence of nanoparticles the heat transfer coefficient will be increased to some considerable extent and the heat transfer enhancement strongly depends on the volume concentration of nanoparticles and Peclet number. Also, comparison with experimental data and literatures’ correlations is carried out which indicates the Dispersion model in both cases is more precise and Homogeneous model (single phase) underestimates the Nusselt number in constant thermo physical properties.

Abstract: Objective: One of the main tasks of the manager in the process of management is the leadership of the organization. The present study aims to investigate the attitude of Kermanshah University of Medical Sciences staff towards the relationship between leadership style and management practices. Methods: This cross-sectional study (descriptive-analytical) was performed on the145 of the staff of Kermanshah University of Medical Sciences that were selected through the quota sampling – random method. The study data were collected using two questionnaires. Frequency distribution, standard deviation, and percentages were used in order to describe the data. Chi-square and ANOVA were also used to analyze the data. Results: Among the 145 subjects, 114 ones were selected to complete the questionnaires. The study results revealed a significant difference between the single and married subjects' attitudes toward the leadership style. Attitudes also varied in different age groups and this difference was statistically significant. In this study, none of the subjects considered their managers' leadership style as collaborative. The study findings revealed a statistically significant relationship between leadership and management experience. Discussion: None of the study subjects mentioned collaborative leadership style for the managers of Kermanshah University of Medical Sciences. This implies that managers are more attentive to the work environment and identify the employees' tasks, but pay less attention to the employees' participation. In a specialized center, collaborative management should replace authoritarian leadership style.

Abstract: Recently, Very Large Eddy Simulation approach has attracted a great deal of attention among researchers. This approach can be thought of as an intermediate approach in flow field filtering view point compared with Direct Numerical Simulation and Reynolds-Averaged Navier-Stokes. One famous method to this approach is Partially Averaged Navier-Stokes. Early studies have demonstrated the capability of this technique in flow prediction; however, this method still needs to be evaluated under more flow conditions to ensure its reliable performance. In this study, the performance of PANS k-ω method in the simulation of turbulent flow around a cylinder with square cross section close to a flat surface, and at Reynolds number of 13200, has been evaluated. Flow around a cylinder provides a good criterion to assess capabilities of the proposed method. To do so, three different filters have been evaluated dynamically and compared with each other and Wilcox k-ω model. Results indicate that at such a Reynolds number, method is as accurate as k-ω method.

Abstract: Background :Shorter length of hospitalization of mothers will be helpful in economical, social terms. Since last few decades oxcytocin infusion has been used for induction of labor, but due to its complications, new drugs need to be evaluated. The efficacy of misoprostol for induction of labor is controversy. Therefore, the effects of vaginal misoprostol on labor time and latent phase were investigated. Materials and Methods: This randomized clinical trial was conducted on 180 pregnant women in 2009 in Mobini Hospital, Sabzevar, Iran. Oxytocin infusion was used in one group and vaginal misoprostol (50mcg) was used in the other one. Total duration of labor and latent phase period in both groups were analyzed by T-student test. All tests were assumed two-sided. Findings: Total duration of labor for misoprostol was 10 hours and for oxytocin was 17 hours (p=0.01). Also latent period phase in misoprostol method was lower than that of Oxytocin(6 hours Vs. 13 hours, respectively) (p=0.01). Cesarean section rate was reported 11% for vaginal misoprostol and 35% for Oxytocin (p=0.01). Conclusion: using misoprostol compared with oxytocin, significantly reduces both the latent phase and the total labor time. Also CS rate is lower in the use of misoprostol compared oxytocin

Abstract: objectives: This study was undertaken to compare post-operative outcomes associated with early oral feeding versus late oral feeding after cesarean section. Materials and Methods: In this randomized clinical trial, 140 pregnant women underwent elective cesarean section with regional anesthesia were randomized in two groups. In the early oral feeding group 2 hours after surgery and in the delayed oral feeding group 8 hours after surgery a liquid diet began for patients. If patients had appropriate tolerate to liquid diet, regular diet began, gradually. The main outcomes for the investigation were included duration of hospital stay, time to return normal bowel function and post-operative gastrointestinal complications. Results: time to return of bowel movement (7.8±2.9 h vs. 11.7±5 h, p<0.0001) and time to mobilization (10.7±7.7 h vs. 13.5±5.9 h, p: 0.015) were occurred significantly earlier in early feeding than late feeding group. We did not show any significant differences between groups in the post-operative gastrointestinal complications. Conclusion: early oral feeding given 2 hours after cesarean section has positive impact to reduce time to return normal bowel function with no significant effect on gastrointestinal complications.

Abstract: In this investigated the concentration of the heavy metals such as lead, mercury, cadmium, nickel and arsenic in the liver tissue of fish Pomadasys Kaakan caught from the Persian Gulf were studied. Determine the concentrations of heavy metals in liver of fish samples were prepared by atomic absorption model (varian vists mpx) was: 1. As = 0.05(ppm), 2. Pd = 0.22(ppm), 3. Cd = 0.60(ppm), 4. Hg = 0.05(ppm). Accumulation of heavy metals, lead and nickel exceeded the standard for human consumption was determined that the cause can be attributed to environmental pollution and type of feeding fish. One of the most fundamental difficulties is accumulated heavy metals in the body which cannot metabolize them. The heavy metals in the some part of body such as in other tissues fat, muscle and bones joints and may accumulate the same conditions which have caused numerous complications in the body. Heavy metal salts and minerals as well as other alternatives are needed in the body which is replaced with zinc and cadmium in food. Also, taking the property of accumulation of heavy metals in plants and enter the food chain, they will have doubled their risks. The growing and extended industry and entered the chemicals in water, soil and air, and contaminated the environment is more likely to encounter human risks.

Abstract: background: The complications such as fever, hematoma, urinary tract infection and blood loss, are more frequent in emergent ceasarean sections (C/S). We have conducted this study to compare the frequency of complications in two types of C/S. Material and Methods: This study conducted in Maternity Research Center (MRC) and two educational hospitals; (Motazedi and Imam Reza) in Kermanshah University of Medical Sciences, Kermanshah, Iran. It conducted on 512 cases of C/S performed in two educational health care centers (256 emergent and 256 elective C/S). Mothers with previous history of background diseases (diabetes, hypertension, lupus, history of twin birth, and history of corticosteroid therapy, microbial and fungal infections) during pregnancy and delivery were excluded from the study. For comparing the complications between two groups we used the, Chi square and Fisher’s exact tests. Results: Our findings indicated that 40.6% of emergent C/S were performed due to disproportionate fetal head to maternal pelvic and 62.1% of elective C/S were performed due to previous C/Ss. APGAR scores of 1-6 were observed in first minute of 4.3% and fifth minute of 1.6% of neonates delivered with emergent C/S, and 3.5% and 0.8% in elective C/S respectively. In general, 12.5% of emergent C/S and 6.6% of elective C/Ss developed complications. Discussions: Our study indicates the C/S complications for both mother and neonate, and these complications are more frequently observed with emergent C/S.

Abstract: In today’s rapidly changing work life, organizational justice has become increasingly important to employees. Prior research shows that Perceived justice is associated with people feelings and behaviors in social interactions. In this article we examine the contribution of distributive, procedural and interactional justice to employee organizational citizenship behavior (OCB). Data was collected through Rego and Cunha (2006) organizational justice and Podsakoff (2000) OCB questionnaires from 102 employees (67 male and 35 female) of Khorasan Razavi province sport and youth organization. The findings of the study revealed that perceived organizational justice and its components have significant impact on employees’ OCB. Moreover, no differences were found between male and female employees regarding these variables. Interactional justice was found to be the strongest predictor of OCB.

Abstract: Organizational citizenship behavior (OCB) has received considerable attention in recent years. It has been studied as behavioral outcome of employees’ motivation in organizations. However, the present study sought to discern the relationship between employees’ perception of empowerment with OCB as voluntary acts beyond the role specification in 75 employees of sport and youth organization of khorasan Razavi province. Data was collected through organizational citizenship behavior and employees’ perception of empowerment questionnaires. Both scales were adapted into farsi. Statistical analysis of the study reveald that mean scores of employees’ perception of empowerment and OCB were low. There was a significant relationship between employees’ perception of empowerment and its subscales with OCB (p < 0/05), a stepwise multiple regression analysis showed that meaningfullness and competence were the strongest predictors of OCB.

Abstract: Today, many advances have been made in recognition and treatment of viral diseases, although the nature of viruses, prevention, and treatment of some of them has remained not very clear. Many unknown viruses in short time have shown detrimental effects on human health, while the number of people who suffering from viral diseases are increased. In this paper, we introduce a new treatment for viral disease by injecting the electrical current into the viral affected environments. In this method, low electrical currents with a set of different parameters are injected to the viruses in laboratory environment, before transmitting them to the cellular environment. Then we have investigated impact of the currents that injected on viruses. During the experiments it was observed that electrical current injection can demobilize the natural viruses. Also, several parameters were tested for electrical currents, and we have tried to find set of parameters not only with the greatest impact on viruses, but also with the least damage on living cells. Finally, we concluded that in case of viral diseases, typical treatments can potentially be alternated by electrical current injection.

Abstract. Due to the extension of attacks to computer networks in the current decade, it is crucial to secure the networks in an appropriate and effective way. One solution is to have a host that supervises the situation for all the computers in the network and makes decision regarding possible attacks. This method is not effective in recently developed networks due to their large extension and high speed. We propose a new distributed intrusion detection system that is based on cooperative agents (‘DIDCA’). Agents are grouped into subsets of agents that are in connection with a leader on top. Leaders of different subsets communicate together to share all the information throughout the network. We simulated our method using DARPA 1999 database and compared it with Snort. Our results showed that our method achieved a better performance.

Abstract: This paper deals with a robust economic-statistical design of control chart, in which the input parameters are expressed as intervals. The design procedure relies on finding the best design parameter set based on the minimax criterion for risks. Genetic algorithm (GA) has been used as a search tool to find the best design (input) parameters with which the control chart has to be designed. The proposed method minimizes the risk of not knowing the true parameters to be used in the design, and is robust to the true parameter values. A numerical example is used to illustrate the performance of the proposed economic-statistical design of the control chart.

Abstract: This paper presents using Imperialist Competitive Algorithm (ICA) and its application to a least-cost Generation expansion planning (GEP) problem. Least-cost GEP problem is concerned with a highly constrained nonlinear dynamic optimization problem that can only be fully solved by complete enumeration, a process which is computationally impossible in a real-world GEP problem. In this paper, Imperialist Competitive algorithm incorporating a stochastic technique and random initial population scheme is developed to provide a faster search mechanism. The main advantage of the ICA approach is that the “curse of dimensionality” and a local optimal trap inherent in mathematical programming methods can be simultaneously overcome. The ICA approach is applied to two test systems, one with 15 existing power plants, 5 types of candidate plants and a 14-year planning period, and the other, a practical long-term system with a 24-year planning period.

Abstract: Deregulation in the electricity industry leads to new challenges in Generation Expansion Planning (GEP), due to the competition among the Generation Companies (GENCOs) and opposing objectives of GENCOs and policy makers. This paper presents the GEP problem in competitive environment and applies the Imperialist Competitive Algorithm (ICA) to solve this problem. The objective of each GENCO is maximization of its profit while the regulatory body is concerned with market and system stabilization trough providing the appropriate signals to investors to avoid the over/under investment. Other objectives of the regulatory body are optimization of generation capacity, maintaining system and national security and maximization of the social welfare. In order to model the competition between the GENCOs and opposing objectives in this problem, the GEP problem is modeled as a Cournot game with Nash equilibrium. The GEP problem is solved iteratively by self-optimizing of each GENCO using ICA and satisfying the regulatory body in Cournot model. The proposed algorithm is tested on a simple case and the results are compared with those drawn in previous works. The obtained results demonstrate the effectiveness of the proposed ICA-based method.

Abstract: Administration of amitriptyline, a most commonly used tricyclic antidepressant, is associated with anticholinergic side effects and rare but severe hepatotoxicity. It supposed that the intermediated metabolites of amitriptyline produced by CYP450 involved in hepatotoxicity but the exact mechanisms involved in hepatotoxicity are unknown. The aim of this study was to determine the mechanism of hepatotoxicity induced by amitriptyline and protective role of taurine in an in vitro model of isolated rat hepatocytes. Markers such as cell viability, reactive oxygen species (ROS) formation, lipid peroxidation, mitochondrial membrane potential, and hepatocytes glutathione content were evaluated every 60 minutes for 180 minutes. Our results showed that amitriptyline resulted in cytotoxicity characterized by the reduction in cell viability, an increase in ROS formation and lipid peroxidation, mitochondrial membrane potential collapse, and a reduction in cellular glutathione content. Our finding showed administration of taurine (1mM) effectively reduced the toxic effects of amitriptyline in isolated rat hepatocytes.

Abstract: Nowadays, software organizations spend much time and resources to analyze and investigate software requirements. Thus some factors like the need to fast software delivery with a high quality, the superiority in competition with other companies, satisfying customers, considering the market dynamics, the change of customer needs, and addressing market challenges have finally led to develop agile methods as well as the requirements issue becomes one of the most important topics. As it is time consuming to define needs at one stage and impossible to spend much time in order to determine requirements completely using traditional ways in agile methods, screening and some other ways are required to identify needs in the agile method. This paper is aimed to study requirements and identify strategies of useful and useless ones to develop the software via agile methods because of the need to the software and different competitions between developers in rapid software providing perfect and with a high quality.

Abstract: An attacker has to ‘scan’ susceptible points of a network before attacking. There are several methods of detection of such behavior which are mostly based on thresholding. As the performance of these methods is highly dependent on the value of threshold, it is crucial to adjust this value appropriately. This adjustment is not always trivial. In this study we proposed a new method to optimize the parameters of the system using genetic algorithms (GA) based on network flows. Subsequently we compared our method with Snort. The results showed a superior performance as measured by the sensitivity index of d’.

Abstract: Because of many advantages of self-propagating high-temperature synthesis, this method is used increasingly for advanced compounds and composite materials production. ZrB2-ZrC composite has unique characteristics, so its synthesis with the least undesirable phases is an important problem for producing this composite. In this research, synthesis of this composite by metallic element as a reductant agent by SHS is done successfully, but elimination of undesirable compounds are costly and difficult. In order to prevent creating these compounds, replacement of metallic element by MASHS process, thermodynamically and practically points of view were studied. According to used mechanical activation conditions, synthesis of desirable composite was not occurred. For this process replacement, the initiating activation energy subject was discussed for achieved results.

Abstract. Computers have been used in education for more than three decades. Computer-based training (CBT) and computer-aided instruction (CAI) were the first such systems deployed as an attempt to teach using computers. Computer-based training has two important branches 1) E-Learning System and 2) Intelligent Tutoring Systems. Both systems have strengths and weaknesses. It is well known that e learning Systems not provide the same kind of individualised attention that a student would receive from a human tutor, as they do not reason about the domain and the learner. This has prompted research in the field of intelligent tutoring systems (ITSs). ITSs achieve their intelligence by representing pedagogical decisions about how to teach as well as information about the learner. They have been shown to be highly effective at increasing students' performance and motivation The goals of learning no longer were solely based on acquiring skills and facts but started to include the strategies and process used by the student to reach mastery of a knowledge domain. This paper reviews ITSs architectures.

Abstract. The application and development of e learning and distance education via the Internet and Intelligent Tutoring Systems (ITS) has been growing inexorably, in recent years. Both systems have strengths and weaknesses. Intelligent Tutoring Systems are typically domain septic and rely on concise knowledge modelling and learner modelling. The goal of the research in the area of Intelligent Tutoring Systems is to build computer-based tutors that achieve the effects of learning individually with a human tutor, while E-learning systems suffer from defects mainly related to the relative absence of the teacher and, therefore, the difficulty of adapting teaching to the level and behaviour of the learner. This paper provides possibilities for convergence of these two areas, and describes two of our experiences in providing an Intelligent Tutoring Systems style approach to eLearning systems.

Abstract: The genus of Prangos consists of about 30 species, 15 of which are growing wildly in many regions of Iran. Prangos ferulacea (L.) Lindl. with the common Persian name of "Jashir" is a perennial and aromatic plant from Apiaceae (Umbelliferae) family which is native to the mountains of southern Iran. P. ferulacea has been used in folk medicine as emulient, carminative, tonic, sedative, antiflatulent, anti-helmintic, antibacterial, antispasmodic, and antidiabetic agents. Monoterpenes, sesquiterpenes, coumarines, flavonoids, alkaloids, tannins, saponins, and terpenoids are some important compounds identified in this plant. Previous researches indicated that antioxidant properties of this plant were higher than α-tocopherole (vitamin E) and the main compounds of P. ferulacea in different growth stages were monoterpenes, specially α-pinene, and β-pinene. The present article aimed to examine the extensive pharmacologic active factors existing in this plant and its potential efficacy mechanisms to be used in medical and pharmacological works in the future.

Abstract: Background and aim: Health and clinical courses, which other marginal factors, irrespective of motivation, may contribute to continuing studies in, are socially important. Therefore, the present study tries to determine the factors influencing continuing studies among health graduates of associate, Shahrekord University of Medical Sciences (SKUMS). Methods: For this descriptive-analytical study, educational profiles of all health graduates of SKUMS between 1365-86 were examined and the data was gathered through a researcher-developed checklist and phone calls. Data analysis was performed by SPSS 16 using Cox regression. Findings: From 398 respondents of the study with a mean age of 22.2 ± 2.25 (range: 20-39), 140 (35.2%) were male and 206 (51.8%) had been admitted to higher education. According to Cox regression, some factors, e.g. age, gender, marital status, residency, and GPA associate, were significantly effective on continuing studies and some others including associate course of study, course period, and diploma GPA had no significant effect on the chance of admission to higher education. Conclusion: Growing older, one gradually enters other living arenas like marriage, making continuing studies marginalized. Therefore, it could be assumed that the factors influencing continuing studies should be considered a whole, i.e., the circumstances should be prepared to facilitate continuing studies before growing older and facing consequent life issues.

Abstract: Increasing development of Combined Heat and Power (CHP) system applications in residential consumption has been resulted in a competitive market between generating power by these units and purchasing it from national grid. In Iran, on account of huge energy subsidies allocations, there has been no opportunity for the mentioned units to compete with the conventional practice of purchasing electricity from national grid up to now. Considering recent government policies, to remove the subsidy related to energy carriers, this paper intends to evaluate the applications of CHP units in residential buildings from economical point of view. For this, HOMER software has been utilized to evaluate the CHP unit placements as well as their utilization manner in order to minimize total energy costs for residential consumers. The results indicate that in the case of removing energy subsidies, the installation of such units will be economically quite cost-effective.

Abstract: The main aim of this study is to conduct the period of training of active athletes competitions blood lipids (triglycerides, cholesterol) and lipoprotein (HDL-C, LDL-C and VLDL) changes in levels of malondialdehyde (MDA) and glutathione peroxides (GPX) levels and to investigate the related effects in this regard. The research group is consisted of twenty volunteer athletes participated in seasonal training within the program of training sessions on a regular basis. Blood samples were taken at the end of the season and before the competition season and plasma MDA, GPX serum, blood lipids and lipoproteins were analyzed in this case. According to the working group cases for the comparison of pre-and post-test analysis of HDL-C (p <0.05) and GPX (p <0.01), significantly differences in the related research were found. Competition of post-MDA levels in serum TG, VLDL and p <0.01 was showed difference between the levels. As a result, the working group making a regular practice of lipid peroxidation did not increase due to the adaptation of MDA in understanding the changes. GPX's recent emergence is due to the cause of low measurements and the fact that athletes could be considered as having an adequate antioxidant defense system. [Fatih Kıyıcı.
