Strategic thinking is the today's need of organizations, especially military organizations. In order to create innovative and effective strategies, the commanders and managers of the highest levels of the Armed Forces of Islamic Republic of Iran should be familiar with the skill of strategic thinking and apply it in strategic defense management. In order for strategic thinking to emerge, it is necessary to provide the necessary contexts and platforms in the organizational environment. In this regard, the aim of this research is to identify the requirements for realizing the strategic thinking of commanders and managers of the highest levels of the armed forces. This is an applied-developmental research and has been done with a case-based method. The method of information collection was library and field, and the data collection tool was a semi-structured interview. A number of 9 experts in this field at the level of the armed forces were selected as a statistical sample in a targeted manner after reaching theoretical saturation. Analysis of information with the method of coding and using the MAXQDA-2020 software was carried out for the validity of the research, acceptability, transferability and verifiability, as well as for the reliability of the research, the credibility of the research, by the research team and finally in a verified expert working group. The findings indicate that the requirements for realizing the strategic thinking of the commanders and managers of the highest levels of armed forces are placed, in 5 components and 58 indicators including structural components (8 indicators), human resources (9 indicators), organizational culture (17 indicators), leadership and management (8 indicators) and general (16 indicators). The aforementioned requirements can be the basis for the realization and development of the strategic thinking of commanders and managers for the aforementioned preparation and will cause the institutionalization of strategic thinking in the main and decision-making body of the armed forces.

Radon, as naturally occurring radioactive gas, is responsible for 50% of the total background radiations in human. Radon gas is able to enter to human body through eating and drinking. So, measurement of received radiation in the human body is essential. In this study, the presence of radon in milk and its dose was examined. This experiment was conducted using 12 Rayeni goats which have been categorized in a completely randomized design by 4 treatments and 3 replication (Treatment A = Radon-containing water + zero antioxidant, Treatment B = Radon-containing water + antioxidant, Treatment C = healthy water + antioxidant, Treatment D = healthy water+ zero antioxidant). The experiment was prolonged for 60 days. During the experiment the goats were milked every day. The samples were transferred to laboratory to determine the milk compounds and properties, as well as to measure its radon level. Presence of radon in milk was detected using Rad7 device. The averaged radon concentration in milk samples (for treatments A and B) receiving radon was about 126 Bq m-3. There was no significant difference between protein. But there was a significant difference between the percentages of fat, lactose, total antioxidant capacity and the number of somatic cells. Radon did not change pH and Malondialdehyde contents of the treatments. We also determined annual received radon dose per person from drinking milk. It was different among age groups. Newborns were at higher risk of internal radon exposure from contaminated milk. Radon can enter thelivestock milk. According to our findings, with, this radon amount in milk was not higher than the allowable level in valid resources for human health.

Following the successful design and construction of a 150keV accelerator tube, the construction of a 200keV electrostatic accelerator system at the Physics Department of the Nuclear Science Research School has been completed. This accelerator includes a 200keV accelerator tube, a high voltage power supply capable of supplying 200kV at 10mA current and a 200kV isolating transformer. An RF type ion source with a system for the control of ion beam could provide ions to the accelerator system. The vacuum system employed is a turbo molecular pumping system coupled with a mechanical rotary pump, where they can provide clean vacuum in the order of 7-10 Torr. In this paper the design criteria and some technical details of the construction of the accelerator system are presented. The construction of this accelerator provides a useful tool for research in various fields and gives an opportunity for the Iranian industry to develop and build accelerator components such as RF, vacuum and accelerator control systems.

An insight into the view of academics of Medical Faculty concerning students’ research could inform planners about strengths and weaknesses as well as potential for improvement in student research. The present study aims to better understanding of perception of academics of Medical Faculty about students’ and academics’ research.

This descriptive cross-sectional study was conducted on participants from medical faculty members at Semnan University of Medical Sciences. A questionnaire containing demographic data, questions about view of faculty mentor’s concerning students’ researches and satisfaction on their profession was handed in to faculty members. Forty five out of 65 questionnaires were completed by faculty members and returned to the researchers. Data were analyzed using suitable statistical methods.

Findings indicated that most of faculty members relatively satisfied with their profession. There was a significant association between job satisfaction level and tendency to research activities. Around 20% of responders showed high interest and about 66% had an average interest in advising students’ research activities. Faculty members believed students showing little inclination toward research works as well as lacking knowledge on research principles. Low income, extended hours of teaching, engagement in private practice, administrative duties, excessive bureaucracy and insufficient research funding are the most frequent challenges in doing students’ research.

It is concluded that most medical faculty members possessed a high inclination toward research activities. Student's needs to receive detailed instructions on research methodology and should be encouraged to consider research as part of their educational programs. Faculty members should be motivated to devote more time and energy towards students’ research activities.
