This study examines and explains the long-term relationship between clean energy consumption (nuclear and renewable) and non-clean energy (fossil energy) and economic growth using panel data during the period 1980-2080. In order to investigate the relationship between variables in the long run, panel causality test has been used. Experimental results show that there is a collective relationship between the variables. According to the results, the revenue elasticity of nuclear energy consumption, renewable energy consumption and fossil fuel consumption is between zero and one, which indicates that nuclear energy, renewable energy and fossil fuels are essential commodities for countries. Also, with a one percent increase in nuclear energy consumption, renewable energy consumption and fossil fuel consumption, GDP will increase by 0.069 percent, 0.176 percent and 0.398 to 0.749 percent, respectively. Short-term causal analysis indicates a two-way causal relationship between fossil energy consumption and economic growth, nuclear energy consumption and renewable energy. The results also indicate a one-way causal relationship between renewable energy consumption and economic growth. Also, in the long run, there is a two-way causal relationship between economic growth, fossil fuel energy consumption and renewable energy consumption, and a one-way causal relationship from economic growth to nuclear energy consumption.

Today, the issue of smuggling has become one of the main concerns of the country; therefore, identifying and prioritizing the factors affecting smuggling of goods is the problem of this research. In fact, we seek to identify the main causes of smuggling of goods in the current circumstances of Iran (Islamic Republic of), according to experts' opinions, which can ultimately solve this problem in the country. The method of answering this question is by referring to the experts in this field and analyzing them through the Fuzzy Delphi method. The results of this research show that among the four categories of economic, cultural-social, legal-judicial and law enforcement factors, legal-judicial, economic and law enforcement agents are effective in goods smuggling. More specifically, the time and appropriate punishment elements of the criminals, the country's foreign exchange system, the discretion of the relevant authorities, corruption in law enforcement agencies, inappropriate tariff policies and the technical weaknesses of the custom system are the main causes of smuggling in the country. Policy makers should pay attention to these factors.

Musculoskeletal disorders are considered the primary health problem among military pilots. Thus, the aim of this study was to investigate the relationship between temperament, Somatotype and some anthropometric variables and prevalence of musculoskeletal injuries in military pilots.

In this cross-sectional study which was conducted in 2020, in Tehran, 100 military pilots from selected Air Force bases were participated. Prediction of injury was assessed by functional movement screen test. The pilots’ temperaments were determined by the standard natural temperament questionnaire. Somatotype was calculated using the Heath-Carter method. Anthropometric data were also collected. The relationship between variables was evaluated by Pearson correlation coefficient and multiple linear regression and the difference between different temperaments in the values of variables was evaluated by one-way ANOVA (P < 0.05).

The mean age, weight and functional movement screen score of the pilots were 34.36±5.94, 84.68±8.55 and 17.99±1.59, respectively. Between cold and wet temperament (P = 0.01), endomorphic component of somatotype (P = 0.001), weight (P = 0.001), Body mass index (P = 0.001), waist (P = 0.001), hip (P = 0.001), flexed arm (P = 0.004) and calf (P = 0.006) circumference had a significant negative relationship with functional movement screen test score. Functional movement screen test showed a significant positive relationship only with ectomorphic component (P = 0.001). There was no significant difference between different temperaments in functional movement screen test score (P = 0.64). Multiple linear regression showed a significant negative relationship only between functional movement screen test score and endomorphic component (P = 0.01).

According to the results, it can be concluded that cold and wet temperament, weight, body mass index and endomorphic component of somatotype as individual characteristics are important factors that inversely related to functional movement screen test score of military pilots that should be considered.

Introduction and Aims: Type, intensity and duration of exercise, determining the effect of exercise on haematological indexes. The aim of this study was comparison of the effects of acute moderate-and high-intensity aerobic exercise on some hematological parameters and exercise-induced thrombocytosis in female college futsal players. Eleven female futsal player of Jahrom University who had at least six months futsal training, voluntarily participated in this study. Subjects, runs on the track and field piste for 30 min at 65 % maximal heart rate in first week and in second week run with 80% maximal Heart rate. Blood was drawn immediately before and after exercise. The results showed that blood platelets (P=0.02), hematocrit (P=0.001), the mean corpuscular volume (P=0.01) was significantly increased after moderate-intensity exercise. Also, blood platelets (P=0.001), the mean corpuscular volume (P=0.01) increased significantly and hemoglobins (P=0.001), and the mean corpuscular hemoglobin concentration values (P=0.001), was significantly reduced after high intensity exercise. There was significant difference in hemoglobins (P=0.007), mean corpuscular hemoglobin (P=0.004) and the mean corpuscular hemoglobin concentration (P=0.002) values between moderate-and high-intensity exercise. Based on the findings of this study, acute exercise with different intensity can have a significant effect on some blood parameters in female futsal academic.

Increase in the number of white blood cells is called leukocytosis which usually can be seen after exercise. This study aimed to investigate the effect of creatine kinase and lactate dehydrogenase on young men's leukocytosis after a session of high intensity interval exercise in the morning and evening.
In this quasi-experimental study, 11 sport sciences male students with an average age of 19.81±0.98 participated. Subjects in two separate sessions at an interval of three days performed high-intensity interval exercise (Based on maximum heart rate) in the morning and evening. In each session, blood samples were taken before and immediately after performing the exercise protocol. Repeated measures analysis of variance and dependent t-test were used to compare changes of variables levels. The relationship between variables were evaluated by Pearson correlation coefficient and the level of statistical significance was set at P The results showed that the concentration of creatine kinase after exercise in the morning (P=0.025), lactate dehydrogenase in the evening (P=0.01), the number of total leukocytes, neutrophils and lymphocytes in both morning and evening (P0.05). There was Significant correlation between creatine kinase and lactate dehydrogenase with lymphocytes in the evening (P The results showed that the muscle damage caused by high-intensity interval exercise in the evening is associated with changes in leukocytes and it seems that the exercise-induced leukocytosis partly could be due to increased indirect markers of muscle damage.

Due to physical and mobility limitations, veterans and disabled people have poorer quality of life and sleep. The purpose of this study was to survey the quality of sleep and life in veterans and disabled professional cycling team athletes participating in the national championship competition.

Fifty-two subjects participated in this descriptive-analytical study, including twenty-six veterans and disabled professional cyclists who had participated in a national championship competition held in Shiraz and 26 volunteer non-athlete veterans and disabled persons selected by convenient sampling. Pittsburgh Sleep Quality Index (PSQI) and SF-12 questionnaire were used to collect data and Mann-Whitney U test and Spearman correlation coefficient were used for data analysis.

There was a significant difference in the total score of quality of life and its scales between the two groups (P<0.05); so that, the cyclist group showed a better status. Also, there was a significant difference between the two groups in total score of sleep quality (P = 0.001) and the constructs of sleep latency (P=0.01), sleep duration (P=0.008), sleep disturbances (P=0.007) and use of sleeping medications (P=0.001); so that, the cyclist group had a lower score in the mentioned items and had a better status. There was no significant correlation between the total score of quality of life and total score of sleep quality in the cyclist (r=-0.14, P=0.49) or non-athlete (r=-0.06, P=0.74) groups.

The present study showed that the veteran and disabled professional cyclists that participated in the national championship had good sleep quality and quality of life compared to the non-athlete disabled persons.

Nurses are constantly facing stressful factors due to the nature of their job. These stressors can affect their physical, psychological and social health. The aim of this study was to investigate the association between physical activity and social health and spiritual intelligence among nurses.
This casual-comparative study was conducted with participation of 86 nurses working in Jahrom's hospitals. Keyes social health and King’s spiritual intelligence questionnaire were used in the study. Data were analyzed via SPSS-18 software.
Participants were categorized as active (n=52) and inactive (n=34), based on their physical activity. The mean (SD) age of active and inactive nurses was 25.7 (5.1) and 25.9 (4.5) respectively. Among spiritual intelligence subscales, a difference was observed in the subscale of state of consciousness (P Physical activity was associated with social health and spiritual intelligence among nurses in Jahrom. We propose that physical activity be included in nurses’ daily schedule.

Studies have shown that acute exercise can increase serum concentrations of cardiac biomarkers, including brain natriuretic peptide (BNP). The aim of this study was to compare of the effects of two types of acute continuous (CE) and intermittent aerobic exercises (IE) on serum BNP concentration and myocardial workload in sedentary men.
Subjects and Eleven sedentary healthy men aged 22.3±1.9 years completed this semi-experimental study. The study was designed as a crossover trial performed on two distinct experimental days separated by a 1-week washout period. Each session consisted of 40 min of aerobic exercise, either IE (60% of reserve heart rate) or CE (intensity alternating between 50% for 2 min and 80% for 1 min), on a treadmill. Measurement of variables were taken before and immediately after each exercise session.
Serum BNP concentration changes after both types of exercises was not significant (P>0.05) and there was no significant difference in BNP concentration between CE and IE (P=0.21). In addition, myocardial workload increased significantly following both exercise protocols (P=0.001) but there was no significant difference between CE and IE values (P=0.2).
According to the results of this study, there was no difference between intermittent and continuous exercises on serum BNP concentration and both types of exercises imposed the same myocardial workload. Increase in BNP was lower than the upper reference limit for ventricular dysfunction.

Managers of organizations in addition to the emphasis on improving efficiency and effectiveness also consider the mental state to improve health and quality of life of employees. The aim of this study was to evaluate the effectiveness of sport on job burnout, general health and life expectancy in Jahrom University of Medical Sciences staff.
60 (29 active and 31 inactive) of Jahrom University of Medical Sciences staff volunteers participated in this cross - sectional study. Information was collected via Maslach Burnout Inventory (MBI), general health (GHQ 28), life expectancy Schneider and demographic characteristics questionnaire. To analyze the data we used of SPSS-18, Kolmogorov-Smirnov test and independent t-test (α = 0.05).
The results showed that active employees compared to inactive employees are in a significantly better position in measures of general health (P = 0.02), But There was no significant difference between two group in the all three factors of burnout (Emotional exhaustion (P = 0.15); depersonalization (P = 0.2); lack of personal accomplishment (P = 0.20), and Life expectancy (P = 0.10).
Activity can improve employee health, so it can be said that through exercise can increase capacity to cope with stress at work and their general health can be guaranteed. Therefore, it is proposed that would provide allow the institutionalization of physical activity and sports organizations.
