This study investigated a posttraumatic stress, social support, and work burden and identified related factors which exerted influence on posttraumatic stress of new firefighters. Data were gathered from total of 144 new firefighters. Also, 22 PTS items, 20 work burden items, and 8 social support items were analyzed by SPSSWIN 21.0 program. Posttraumatic stress according to general characteristics showed significant difference in gender(t=-2.57, p=0.01), experience of self danger(t=3.06, p=0.00), experience of rescuee danger(t=2.41, p=0.02), and experience of colleague danger(t=3.43, p=0.00). High risk group of PTS was 20.1%. Posttraumatic stress, social support, and work burden showed significant difference in the high and low risk group. Posttraumatic stress was correlated with work burden(r=0.34, p=0.00), social support(r=-0.29,p=0.00). Factors influencing PTS were Experience of colleague danger(${\beta}$=1.274, 95% CI=0.08-0.96), social support(${\beta}$=-0.090, 95% CI=0.85-0.98) and work burden(${\beta}$=0.057, 95% CI=1.02-1.10). We need to reduce the work burden caused by influencing variable of traumatic stress and create more preventive discipline of traumatic stress for the new firefighters to improve the social support at work or home. Also, posttraumatic stress has to be managed consistently with support by changing the social attitudes and we need to seek the new system that anybody can get a consultation of a specialist.

Yoga is an ancient Indian system of life, encompassing various practices including practices for self-discipline and also for regulating the health states of the individual, being practiced for thousands of years. The present study aims at understanding the effect of two high frequency breathing practices over autonomic nervous system. Forty healthy male volunteers of age $21{\pm}2$ years with $9{\pm}3$ months of Yoga practice experience were recruited. The two high frequency Yoga breathing practices, kapalabhati (KB) and bhastrika (BH) were given as interventions randomly on either of the two days to minimise laboratory bias. They were assessed before and immediately after the interventions for heart rate, respiratory rate, heart rate variability (HRV), blood pressure and peripheral oxygen saturation. There was a significant increase in heart rate (p<0.01; p<0.001), systolic blood pressure (p<0.01; p<0.001), NN50 (p<0.01; p<0.001) component of HRV for both KB and BH groups respectively. There was a significant reduction in respiratory rate in both the groups (p<0.001, and p<0.05, BH and KB respectively) immediately following intervention. A significant increase in LF component of HRV and reduction in Diastolic blood pressure and high frequency (HF)component following KB was also observed (p<0.05, for all comparisons). The Mean peripheral oxygen saturation remained unaltered in both the groups (p>0.05).The results suggest that high frequency yoga breathing practices induce physiological arousal immediately as evidenced by increased blood pressure and heart rate. The sympathetic arousal was more following KB session as evidenced by an increased diastolic blood pressure, LF power and a decrease in HF power of HRV as compared to the BH session.

Purpose: The purpose of this study was to describe the current status of managing educational programs for tobacco use prevention at middle and high schools located in Busan. Methods: Using a survey method with a 29-item self-administration questionnaire, the data were collected from January 10 through February 18, 2005, from school nurses as well as teachers major in healthcare of 227 participant schools. Results: A strategic plan for school-based educational programs of tobacco use prevention was mainly developed by a school nurse at middle school and a teacher in charge of school discipline at high school. The educational programs for tobacco use prevention were implemented for approximately 40% of schools in Busan with the budget ranged from 110,000 won to 200,000 won a year. Eighty five percepts of the schools had anti-tobacco regulations and guidelines in place. Twenty two percents of the middle and high schools collected the data regarding adolescents' smoking status periodically. Over 70% of schools provided tobacco use prevention education programs as a part of regular semester curriculum. Conclusions: For making the management of educational programs for tobacco use prevention effective and consistent with government's anti-smoking policy, schools need (a) development of tobacco management guideline and regulations with participation of teachers, students, and parents, (b) clear job and role descriptions for personnel to plan and implement anti-tobacco programs, (c) compilation of the budget enough to implement the programs, (d) periodically assessment of adolescents' smoking status, and evaluation of the programs to monitor whether those are effective for adolescents' health promotion; and (e) to make an effort to less range of quality in educational programs for tobacco use.

Background: Cigarette smoking is as the leading cause of cancer mortality and other chronic diseases in males worldwide. The prevalence of cigarette smoking is different across and within countries by age, education level, occupation, and so on. This study aimed to determine the prevalence of cigarette smoking and its relationship with individuals' demographic factors and BMI in adolescent men living in Tehran, Iran. Materials and Methods: This study involved secondary analysis of the 'Urban Health Equity Assessment and Response Tool-2' survey conducted in Tehran, Iran, among men aged 20+, 2011-2012. Using a multistage sampling method, 45,990 men were included in the study. The cigarette smoking status, BMI and demographic factors measured through a self-administered questionnaire. Chi-square, t-test, and logistic regression model were used to examine the relationships between the independents variables and cigarette smoking behavior, using SPSS software version 21. Results: In the total of 45,990 men, the overall prevalence of cigarette smoking was 14.6% (CI 95%: 14.29-14.94). Age (OR=0.96; CI 95%:0.94-0.98), house ownership (OR=0.68; CI 95%: 0.64-0.72), job status (OR=0.60; CI 95%: 0.46-0.86), marital status (OR=0.42; CI 95%: 0.39-0.47) and educational levels (OR=0.50; CI95%: 0.45-0.54) were associated with the prevalence of cigarette smoking. However, associations with BMI, family size, residency years, and district were not statistically significant. Conclusions: Given the relatively high prevalence of cigarette smoking in the study population, policy interventions are required to address this major public health issue, with a focus on the population demographic influences.

Breast cancer is the leading cause of morbidity and mortality globally but has an even more significant impact in developing countries. Pakistan has the highest prevalence among Asian countries. A general lack of public awareness regarding the disease often results in late diagnosis and poor treatment outcomes. The literacy rate of the Southern Punjab (Pakistan) is low compared to its Northern part. It is therefore vital that university students and especially medical students develop a sound knowledge about the disease so that they can spread awareness to others who may be less educated. This study therefore considers current knowledge and understanding about the early signs of breast cancer amongst a study group of medical and non-medical university students of the Southern Punjab, Pakistan. A cross-sectional descriptive analysis of the university students was carried out using a self-administered questionnaire to assess their awareness of breast cancer from March to May 2014. A total of 566 students participated in this study, out of which 326 were non-medical and 240 were from a medical discipline. Statistical analysis was carried out using Graph Pad Prism Version 5 with a significance level set at p<0.05. The mean age of the non medical and medical participants was 23 (SD 2.1) and 22 (SD 1.3) years, respectively. Less than 35% students were aware of the early warning signs of the breast cancer development. Knowledge of medical students about risk factors was significantly better than the non medical ones, but on the whole was insufficient. Our study indicated that knowledge regarding breast cancer was generally insufficient amongst the majority of the university students (75% non-medical and 55% medical) of Southern Punjab, Pakistan. This study highlights the need to formulate an awareness campaign and to organize conferences to promote breast cancer awareness among students in this region.

The harshness of legionellosis differs from mild Pontiac fever to potentially fatal Legionnaire's disease. The increasing development of drug resistance against legionellosis has led to explore new novel drug targets. It has been found that phosphoglucosamine mutase, phosphomannomutase, and phosphoglyceromutase enzymes can be used as the most probable therapeutic drug targets through extensive data mining. Phosphoglucosamine mutase is involved in amino sugar and nucleotide sugar metabolism. The purpose of this study was to predict the potential target of that specific drug. For this, the 3D structure of phosphoglucosamine mutase of Legionella pneumophila (strain Paris) was determined by means of homology modeling through Phyre2 and refined by ModRefiner. Then, the designed model was evaluated with a structure validation program, for instance, PROCHECK, ERRAT, Verify3D, and QMEAN, for further structural analysis. Secondary structural features were determined through self-optimized prediction method with alignment (SOPMA) and interacting networks by STRING. Consequently, we performed molecular docking studies. The analytical result of PROCHECK showed that 95.0% of the residues are in the most favored region, 4.50% are in the additional allowed region and 0.50% are in the generously allowed region of the Ramachandran plot. Verify3D graph value indicates a score of 0.71 and 89.791, 1.11 for ERRAT and QMEAN respectively. Arg419, Thr414, Ser412, and Thr9 were found to dock the substrate for the most favorable binding of S-mercaptocysteine. However, these findings from this current study will pave the way for further extensive investigation of this enzyme in wet lab experiments and in that way assist drug design against legionellosis.
