Introduction: This study aimed to assess the level of awareness and performance of non-medical personnel at Shoushtar Faculty of Medical Sciences, Iran, regarding basic cardiopulmonary resuscitation.Materials and Methods: A total of 119 non-medical personnel from Shoushtar Faculty of Medical Sciences, Iran, participated in this study after obtaining their informed consent. Data was collected using a researcher-made questionnaire on awareness and performance in cardiopulmonary resuscitation. The questionnaire consisted of 21 multiple-choice questions. A correct answer was assigned a score of 1, while an incorrect answer received a score of zero. Data was analyzed using statistical tests in SPSS 21.Results: Out of the 119 participants, 76 (55.4%) were women and their average age was 32.63 ± 8.86 years. The average level of awareness among the participants was 6.68 ± 3.40 out of 11, and the average performance level was 3.54 ± 1.25 out of 10, indicating a good level of awareness but poor performance. Participants with a master's degree or higher education and those who received formal training demonstrated higher levels of awareness and performance (P<0.05). Additionally, the mean performance score of women was higher than that of men (P<0.001).Conclusion: The study findings confirmed that while the awareness of the personnel about cardiopulmonary resuscitation was good, their performance was unsatisfactory when it comes to managing a patient with cardiac arrest in a non-hospital setting.

Background: Anoxic-oxic (A/O) is a new method of wastewater treatment and is being used in Mahdishahr wastewater plant. considering the lack of studies in this area, it seemed necessary to study the performance of A/O system in wastewater treatment. This study was carried out to evaluate the efficiency of Mahdishahr wastewater Treatment Plant. Materials and Methods: The present cross sectional study was conducted in 2014 during 8 months. Sampling was performed two times per week from the incoming wastewater, aeration pond and effluent. Overall, 200 samples were collected. The efficiency of Treatment Plant was measured by TSS, BOD5, COD, MLSS, MLVSS, and SVI indices in aeration ponds based on standard method. Then the datas were analyzed by statistical analysis. Results: The mean concentrations of BOD5, TSS and COD in influent were 221.6 mg/l, 203.8mg/l and 321 mg/l respectively. The mean concentrations of BOD5, TSS and COD in effluent were 23.65 mg/l, 16.79 mg/l and 34.9 mg/l respectively. According to the results the average removal efficiency of BOD5, TSS and COD were about 87.25%, 91.77% and 87.29% respectively. These results are in accordance with standards of Iranian Department of Environment to be used for agricultural purposes. During the study, the monthly mean for SVI was 67.3 ml/g and the mean for MLSS and MLVSS was 1880 and 1182 mg/l respectively. Conclusion: in present study, the efficiency of A/O process in COD removals is approximately 89 percent, representing high degradability of wastewater in A/O reactor. In addition, according to the results this method was efficient and the effluent complied with Iranian standards in terms of COD, TSS and BOD5, thus the flow is suitable for reuse or discharge to water courses.

Background and Objective: Learning is regarded as one of the most important abilities of nervous system and without it the life of an individual disrupted. In fact, the learning process contributes to the organism so that it can adapt the ever – changing environment. Therefore, understanding the mechanisms involving in the learning and factors affecting on it is among the issues which have attracted the attention of many psychologists and neurologists. Motivation is one of the most important factors affecting learning and can relate evolving identity to learning. Methods and Materials: The present study is a nonexperimental design (correlation) that by using a structural model investigated the relationship between variables. Multi –stage sampling was used for selecting 1072 participants among Sabzevar and Neyshabour second grade high schools girl students. Three questionnaires were used: identity style scale ( ISI), goals achievement scale and motivational strategies for learning.(1) validity and reliability of the scales was tested by confirmatory factor analysis and composite reliability. The data has been analyzed by using path analysis method. Results: lnformational style had both direct and indirect effect on cognitive engagement. Both effects are statistically significant (P
