Blended learning has many advantages to overcome the adult learning challenges such as limitation of time, external responsibilities and family commitments. So, this study was conducted to determine the effect of blended learning on educational outcome of discontinuous undergraduate students  of operating room.

This is a quasi-experimental study and educational intervention that was conducted in 2018 in Alborz University of Medical Sciences. The study sample consisted of 56 discontinuous undergraduate course students of operating room were included in the study through convenience sampling. The educational intervention was conducted in the form of blended Learning and then the educational outcomes were evaluated with the variables include students' satisfaction, learning and the amount of interactive time in cyberspace to participate in the lessons. Data collection tools in the satisfaction variable was a 15 item researcher-made questionnaire, in the learning variable, a standard MCQ exam and in the interaction time variable, a checklist was developed for recording students' activities in cyberspace for questioning and answering, or express experiences. Data was analyzed using descriptive statistical tests, Paired t-test, T-Test, Anova and Kendall’s and Pearson’s correlation coefficients through SPSS .

Based on the results, all students were satisfied with this method of teaching. The result of MCQ exam showed that there was significant difference in pre and post-tests (t= -4.81, P= 0.001) Also, the mean time of students’ interaction in cyberspace was nearly 10 hours in 12 teaching session, that is a significant time. Pearson correlation coefficient showed a significant negative relationship between the mean age and the mean hours spent in the virtual space of the class to present the task (P = 0.001)

According to  the  positive impact of this method, it is recommended as an effective method of education for discontinuous undergraduate course students of operating room.

The choice of a suitable and ideal dressing for managing of pilonidal cystectomy wound with open technique is very valuable. Therefore, the present study was carried out to Investigation of the effect of dressing by using of hydrogel and alginate products compared to simple dressing method on the wound healing process caused by pilonidal cystectomy, the pain experienced by patients when changing dressing, the cost of treatment and the length of their absence from work. The present study is part of a clinical trial study. That was performed on 40 patients who were candidates of pilonidal. After random sampling, patients were randomly assigned to one of two groups, simple or alginates groups. After using two methods, the length and depth of the wound, each week, were measured and recorded for one month. Data were analyzed using SPSS 19 software with descriptive and inferential statistics. The wound healing from the third week in the modified modern dressing group showed a significant growth compared to the simple group (p <0.001). Also, the severity pain reduces after the second week in the alginate group in comparison of the simple group. In assessing the average costs and the number of absences from work, the total cost spent during a month, there was a significant difference between two groups, and on average, the patients in the alginate  group, returning to their work four days earlier. According to positive results of this study about applying the modern modified method to wound healing and patient recovery, it is recommended to use this technique in open  wound dressing.

Decreasing stressors in critical occupations such as operating room staff is quite valuable. Therefore, by identifying the level of emotional intelligence and coping styles of the operating room staff, these factors can be managed and controlled. The current study aimed at determining the level of emotional intelligence and its relationship to coping-with-stress styles among technologists in operating rooms of educational hospitals affiliated to Iran University of Medical Sciences in the academic year 2015-2016.
The current descriptive-analytic study was conducted on 200 operating room technologists. The instruments employed in the study were questionnaires of demographic information, emotional intelligence by Bradberry and Greaves, and coping-with-stress styles by Endler and Parker. Data analysis was conducted with SPSS version 19.
Based on the result of the current study,71.5% of operating room technologists had moderate emotional intelligence, their dominant style was the problem-oriented style, and there was a significant correlation between emotional intelligence and coping styles (P Emotional intelligence of most of the technologists in operating room was at the moderate level and the dominant style was the problem-oriented. Since emotional intelligence skills and the type of coping styles can be developed through education, it is recommended that educational classes and workshops be held periodically to improve the level of emotional intelligence and selecting the suitable type of coping style by technologists in operating room.

Factors such as high work load, high number of staff, high traffic, and patients’ critical condition make this unit one of the regions with very high risk of infection. In order to prevent infection in the operating room, several actions are taken including washing and disinfection of floor, wearing the cleaned and disinfected shoes or cover of shoes. This study aimed to investigate the contamination of shoes in the operating rooms of the Alborz University of Medical Sciences hospitals.
The present cross sectional study was done on 150 shoes of personal in the operating room of the Alborz University of Medical Sciences hospitals. Samples were prepared and cultured. Then result of cultures was interpreted by expert laboratory staff. Data were analyzed by Fisher's exact test, χ2 using SPSS19 software.
As of 150 samples, 11% were non-contaminated and 89% were contaminated. Before washing, 96.5% of the shoes were contaminated. After washing, however, the percent of the contaminated samples decreased to 61.7%.
Due to the high contamination of the shoes, it seems that the type of washing or type of detergent used without disinfecting ability is significant and should be reconsidered and corrected.
