Natural renewable energy sources are abundant and economically attractive, with zero or very low carbon emissions. On the other hand, harsh environmental and weather conditions, such as soil and dust accumulation, affect the efficiency of renewable energy sources and systems. Accordingly, the need for automated inspection of photovoltaic panels is becoming more critical as the demand for new solar energy system manufacturing and installation increases worldwide. This study introduces a new dataset of images of dusty and clean plates. Furthermore, a new convolutional neural network architecture is proposed to detect the voltage generated by the panel. In the following, the parameters taken from the environment and the voltage estimated by the proposed neural network are analyzed using the random forest regression algorithm, and the panel's efficiency is calculated. The proposed process deals explicitly with detecting dust accumulation in photovoltaic panels. The results obtained in this work have experimentally shown that the proposed system produces high detection rates. The proposed new method leads to the implementing of a more effective and efficient automatic cleaning technique for photovoltaic panels.

Cerebrocardiopulmonary resuscitation (CPCR) is an important and complex process in treatment of cardio-respiratory arrest. Multiple factors affect the quality and success rate of this process. This study aimed to assess the administration of drugs in CPCR using the existing standards and determine the effect of education in this regard. The study was conducted as a quasi-experimental research. All the personnel involved in CPCR processes applied in the Emergency Ward of Pimaneah Hospital were recruited as the study samples. With regard to the main goal of this research, the performance of the personnel on 30 CPCR processes was evaluated before the educational program by an observational checklist made by the researcher. Then a workshop was held for all of the personnel. Then their performance on 30 CPCR processes was reevaluated. The results were then compared. Comparison of the data shows that the rate of standard administration of CPCR drugs after the educational program increased, but no significant relationship was found except for the mean use of epinephrine (P= 0.001). The present study indicated that continuous assessment of CPRC processes, educational workshops and provision of appropriate feedback to health workers can increase the rate of standard administration of CPCR drugs.

Clinical teachers have an important role in creating an environment for effective clinical teaching to students. In addition, the faculty has a significant impact on the student's feeling of success or failure in professional competence. This study was performed to determine the characteristics of an influential instructor according to the nursing student's viewpoints in Jahrom University of Medical Sciences.

In this cross-sectional survey, 75 nursing students of Jahrom University of Medical Sciences were selected by census sampling method. The data collection tool was a valid and reliable questionnaire consisting of 4 domains including professional competence, interpersonal relationship, personality characteristics, and teaching ability. The data were analyzed by SPSS.

The results showed that influential clinical teacher must be professionally competent (mean=4.4 ± 0.80), have interpersonal relationships (mean=4.2 ± 0.96) have good personality characteristics (mean=4.1 ± 0.95), and have high eaching ability (mean=4 ± 0.89). According to the students, the most important characteristics of an influential clinical instructor are having interest in patient care (98.4%), having sufficient professional knowledge (80%), explaining and demonstrating new nursing techniques (80%), performing nursing skills procedures (86.3%), being honest with the students and creating motivation in students (83%).

The nursing student's viewpoints indicated that influential clinical instructor has an important role in promoting quality nursing experience and in getting knowledge, professional skills and attitude. Nursing faculty should plan for promoting professional competency in clinical instructors.

Postnatal depression is a key concept for mother-infant mental health. Evidence of its impact on the mother and infant relationship has been increasingly reported in recent years. Therefore an optimal intervention is important for women and their babie's mental health. Identifying risk factors of postnatal depression and development of screening systems are required. Validation of EDPS was conducted on a sample of 230 women who were within their 8th week of postpartum. The structured diagnostic test

One of the most important threats to health care staff is accidental sharp instruments injuries that may transmit blood born pathogen such as hepatitis BC and HIV virus to health care staff. The main objective of this study was to determine injuries caused by sharp instruments among Jahrom university of medical sciences hospitals health care worker In this deh1ive study the total number of 298 health care staff working in Peymanieh and Motahari hospitals in Jahrom were included. A questionnaire was designed to collect data and then the data was analyzed using SPSS software. The data indicated that 47.3 % of the staff had a positive history of sharp instruments injuries and the most common in juries were among the nurses (50.3%). The most causes of damage was Needle Stick injuries (44.4%) that occurred in operating room ward (27.7 %). 56% of damages happened in the morning. Among staff 92.3% received hepatitis B vaccine. based on the findings providing preventing measures and continuous training course and educational conferences to decrease such injuries in health care staff is necessary.
