Abstract
Background and Aim: In addition to having an acceptable academic level in the field of self-relief and other relief, the combatant must have the necessary available supplies and equipment in sufficiently to prevent injuries from escalating before the medical team arrives and takes care of your life. The present study was conducted to design a military self-relief bag in the Navy.
Methods: The present study is applied research. Thematic literature was used to collect the required data and based on it, as well as the experiences of research team, the modeling was developed. The opinions of the experts were asked by a questionnaire to design a self-relief bag.
Results: The self-relief bag, in size of 15x18 cm and made of soft military and waterproof tarpaulin, was sewn in such a way that it could be installed on the thighs, belts, cuffs, back straps and backpacks. Based on the results of the analysis of the experts' opinions, a list of pharmaceutical items and medical and health equipment items gained the necessary credibility to be included in the Iranian military self-relief bag. The weight of the bag will be 1200 grams in full charge mode (containing all drugs and equipment).
Conclusion: Due to the appropriate weight of the designed bag, the appropriate material and resistance to water and fire, the appropriate location of the bag on the body surface as well as the appropriate and practical contents can be a suitable tool for combatants.

Abstract
Fungal diseases, especially superficial and cutaneous forms (dermatophytes) are of great public health importance due to the possibility of transmission from people to others, especially where people live in groups. Lack of knowledge about how to prevent the transmission of these diseases can cause them to be transmitted to numerous people and carry a large financial burden and even significantly reduce the efficiency of people. Therefore, informing different segments of society about the prevalence of fungal diseases, ways and symptoms of its infection, ways to prevent its transmission to others and necessary measures in case of infection, can play a significant role in promoting public health.
Dermatophyte infections are one of the most important health problems in the world and affect millions of people worldwide. It is estimated that 10-20% of people will develop these infections in their lifetime. The distribution of these infections varies in different countries in the world and it is more prevalent in developing countries than in industrialized countries. So far, more than 40 species of dermatophytes have been identified, which are classified into three genera: Microsporum, Trichophyton, and Epidermophyton.
Dermatophytosis infection has several clinical forms that are classified according to the location of the infection; fungal infection of the feet, arms, legs, trunk, hands, palm and groin area, the scalp and hair the fingernails and toenails, and the nail bed. In addition to dermatophytes, other filamentous fungi can cause superficial and cutaneous infections. Yeasts such as Candida can also cause superficial and cutaneous infections.
These diseases always cause problems such as pain, discomfort, disability, time consuming and high treatment costs. To combat dermatophytosis, it is necessary to know the regional dermatophytes and the extent of their spread, and also having instructions for the prevention of fungal diseases that its implementation can be effective in reducing these diseases.

Abstract
Background and Aim: Marine algae is one of the best sources of bioactive substances. In the present study, optimization of effective factors (time, temperature and solvent concentration) on the extraction of antioxidant compounds of extract of brown algae Sargassum glaucescens in Chabahar beaches with the artificial neural network was conducted.
Methods: Sargassum algae was extracted with methanol at three times (1, 3 and 5 hours), three temperatures (24, 47 and 70 ° C) and three concentrations (60, 80 and 100%). DPPH free radical scavenging activity method was used to evaluate its antioxidant properties. Total phenolic compounds were measured according to the standard method. Artificial neural networks (multilayer perceptron with hyperbolic tangent function) with 1 latent layer and 5 neurons were used to optimize the extraction of antioxidant compounds from sargassum algae extract.
Results: The amount of total phenolic compounds in the extract of Sargasom algae was 3.2±0.56 mg Galic acid/g extract. The artificial neural network predicted the antioxidant properties of sargassum algae with a coefficient of determination of R2=0.9439 and Root mean square error (RMSE) of 1.465654. A positive and significant correlation was observed between observed and predicted antioxidant properties. The optimal extraction conditions of antioxidant compounds based on the artificial neural network method were 100% concentration, temperature 70 ° C and time 5 hours.
Conclusion: According to the present findings, the artificial neural network has good potential to predict the optimal extraction conditions of sargassum algae to determine the antioxidant properties using a multilayer perceptron with hyperbolic tangent. High concentration of total phenolic compounds in sargassum algae extract may be the reason for its antioxidant properties.

Abstract
Background and Aim: Occupational stress in the Intensive Care Unit (ICU) has a serious impact on the health and quality of life of nurses. Paying attention to the quality of life of nurses and reducing occupational stress can lead to better provision of medical services in the ICU and hospital. Therefore, the present study was conducted to determine the relationship between occupational stress and quality of life in ICU nurses in selected naval hospitals.
Methods: In this descriptive-analytical study, 76 ICU nurses in selected naval hospitals in the south of Iran in 2019 participated. Sampling was done by census and available methods. The research tools included the 26-question quality of life (WHOQOL-BREF) and occupational stress questionnaires, which were completed by nurses, and then data were analyzed.
Results: The mean score of occupational stress and quality of life in ICU nurses in selected naval hospitals were estimated as 42.9±1.7 and 62.3±19.1 respectively, both of which are at a moderate level. Occupational stress has an inverse and significant relationship with quality of life in ICU nurses. Occupational stress and quality of life had no significant relationship with any of the ICU nurses' demographic variables.
Conclusion: The findings of the present study demonstrated that there is a significant and inverse relationship between the quality of life and occupational stress in ICU nurses, so the increase in occupational stress of ICU nurses has a negative effect on their quality of life, and this can affect the quality of providing clinical care in hospital. Therefore, improving the quality of life and reducing occupational stress should be on the agenda of health officials.

Abstract
Background and Aim: Some mortality due to stroke occur outside the hospital. Therefore, the pre-hospital emergency medical services (EMS) plays an important and vital role in the management of stroke patients. The present study evaluated the knowledge of prehospital emergency medical services (EMS) personnel in the diagnosis of stroke patients.
Methods: This cross-sectional study was conducted in hospitals and pre-hospital EMS affiliated to Ilam University of Medical Sciences, Ilam, Iran in 2022. In order to measure the knowledge and awareness of pre-hospital EMS personnel regarding stroke, a researcher-made questionnaire containing 20 questions, as well as demographic data such as age, gender, field of study was collected.
Results: The mean age of 109 pre-hospital EMS personnel was 32.4±6.6 years old. Most of them were graduates of associate degree in emergency medicine. The mean score of knowledge obtained by the pre-hospital EMS personnel was 16.9±3.5 out of 20, which according to the grading, the knowledge level was estimated to be very good. Of course, very weak and weak level of awareness was recorded in 0.9% (n=1) and 1.8% (n=2) of pre-hospital EMS personnel, respectively. No significant relationship was recorded between the mean level of knowledge and field of study.
Conclusion: The findings of the present study showed that the level of knowledge of Ilam pre-hospital EMS personnel in the field of stroke is favorable, however, the knowledge of a very small percentage of them was at a weak or very weak level. It is recommended conducting more studies in this field.
