Purpose: The purpose of this study was to examine late-onset hypogonadism, erectile dysfunction, depression, and quality of life among middle-aged male workers. Methods: The subjects included 343 men aged between 40 and 64, responded to self-report questionnaires on general characteristics, late-onset hypogonadism, erectile dysfunction, depression, and quality of life. Data were collected from May 16, 2012 to October 9, 2012 and analyzed using t-test, ANOVA, $x^2$-test, hierarchical multiple regression. Result: The prevalence rate of late-onset hypogonadism was 63.8% with high points in reduction of libido, energy, physical strength and endurance, and erectile function. There were significant differences in late-onset hypogonadism according to age($x^2$=8.98, p=.048) and in erectile dysfunction according to age(F=11.03, p<.001), monthly income(F=2.84, p=.024) and smoking( t=2.96, p=.018). Significant differences were also found in depression according to educational level(F=8.12, p<.001) and in quality of life according to monthly income(F=7.21, p<.001). The factors which influenced quality of life were late-onset hypogonadism, erectile dysfunction, depression, marital status and religion. Conclusion: Symptoms of erectile dysfunction can be improved by smoking cessation education program. In order to improve the life quality of middle-aged men, nursing intervention programs that would both provide proper knowledge on climacteric syndrome and alleviate symptoms should be designed while, at the same time, other programs to evaluate, prevent and control depression are developed.

This experiment was conducted to determine the extent to which susceptibility to cortisol-induced follicle shutdown is influenced by fleece phentotype. Twenty Finewool (10 sheep low fibre diameter, low coefficient of fibre diameter-LL and 10 low fibre diameter, high coefficient of variation of fibre diameter-LH) and twenty Strongwool (10 low fibre diameter, low coefficient of variation of fibre diameter-HL and 10 high fibre diameter and high coefficient of variation of fibre diameter-HH) sheep of 9 months of age were individually penned in an animal house and were injected intramuscularly with an aqueous suspension of hydrocortisone acetate at a rate of 1.42 mg/kg body weight for a period of two weeks. Fibre diameter was measured from clipped tattooed patch wool samples. Follicle activity was measured by histological changes in skin biopsies taken weekly. Blood samples were collected at two-week intervals and plasma cortisol measured. Increased plasma cortisol concentration significantly (p<0.05) reduced clean wool production and mean fibre diameter dropped to its lowest level four weeks after commencement and two weeks after the cessation of cortisol injection. Elevation of plasma cortisol concentration significantly (p<0.0001) increased the percentage of inactive follicles two weeks after injection started. High fibre diameter groups (Strongwool sheep; i.e. HL+HH) had significantly (p<0.0001) higher percentage of follicle shutdown than low fibre diameter groups (Finewool sheep; i.e. LL+LH). Average percentage of shutdown follicles for Finewool (LL+LH) and Strongwool (HL+HH) Merino sheep was $9.8{\pm}0.9$ and $13.5{\pm}0.9$ respectively. Shutdown of primary follicles was more pronounced in Finewool than Strongwool sheep. There was no significant effect of coefficient of variation of fibre diameter on propensity to follicle shutdown induced by exogenous cortisol. It is concluded that elevation in plasma cortisol concentration is inhibitory to the normal activity of follicles in Strongwool sheep but that variation in fibre diameter has little or no effect.

BACKGROUND: Soil bacteria play important roles in organic matter decomposition and nutrient cycling during the non-growing season. The purpose of this study was to investigate the effects of soil management and chemical properties on the utilization of carbon sources by soil bacteria in paddy fields. METHODS AND RESULTS: The Biolog EcoPlate was used for analyzing community-level carbon substrate utilization profiles of soil bacteria. Soils were collected from the following three types of areas: plain, interface and mountain areas, which were tested to investigate the topology effect. The results of canonical correspondence analysis and Kendall rank correlation analysis showed that soil C/N ratio and NH₄⁺ influenced utilization of carbon sources by bacteria. The utilization of carbohydrates and complex carbon sources were positively correlated with NH₄⁺ concentration. Cultivated paddy fields were compared with adjacent abandoned fields to investigate the impact of cultivation cessation. The level of utilization of putrescine was lower in abandoned fields than in cultivated fields. Monoculture fields were compared with double cropping fields cultivated with barley to investigate the impact of winter crop cultivation. Cropping system altered bacterial use of carbon sources, as reflected by the enhanced utilization of 2-hydroxy benzoic acid under monoculture conditions. CONCLUSION: These results show that soil use intensity and topological characteristics have a minimal impact on soil bacterial functioning in relation to carbon substrate utilization. Moreover, soil chemical properties were found to be important factors determining the physiological profile of the soil bacterial community in paddy fields.

Purpose: The purpose of the study was to compare community residents' perceptions, participation, satisfaction, and behavioral changes between a health promotion demonstration health center and general health center. Method: The design of the study was ex-post facto that compared community residents in demonstration health centers and general health centers. The sample included 2,261 community residents who were conveniently selected from demonstration (792 participants) and general health centers (1,496 participants). Result: The results of the study were as follows: 1) Perception and participation rates of exercise, nutrition, and hypertension management programs were significantly higher in the participants of demonstration health centers than those of general health centers.; 2) Satisfaction rates of all programs except the smoking cessation program were significantly higher in the participants of demonstration health centers than those of general health centers. However, only the exercise rate among risk behaviors of participants was significantly higher in demonstration health centers than general health centers. Conclusion: Systematic efforts for health promotion were effective not only in improving the community's awareness, participation, and satisfaction of the program, but also in changing health behaviors. This evidence should be used to foster and disseminate health promotion programs toother health centers to improve community residents' health status and quality of life.

Background: Although nicotine dependence plays a role as a main barrier for smoking cessation, there is still a lack of solid evidence on the validity of biomarkers to determine nicotine dependence in clinical settings. This study aimed to investigate whether urinary cotinine levels could reflect the severity of nicotine dependence in active smokers. Materials and Methods: Data regarding general characteristics and smoking status was collected using a self-administered smoking questionnaire. The Fagerstr$\ddot{o}$m test for nicotine dependence (FTND) was used to determine nicotine dependence of the participants, and a total of 381 participants were classified into 3 groups of nicotine dependence: low (n=205, 53.8%), moderate (n=127, 33.3%), and high dependence groups (n=49, 12.9%). Stepwise multiple linear regression model and receiver operating characteristic (ROC) curves analyses were used to determine the validity of urinary cotinine for high nicotine dependence. Results: In correlation analysis, urinary cotinine levels increased with FTND score (r=0.567, P<0.001). ROC curves analysis showed that urinary cotinine levels predicted the high-dependence group with reasonable accuracy (optimal cut-off value=1,000 ng/mL; AUC=0.82; P<0.001; sensitivity=71.4%; specificity=74.4%). In stepwise multiple regression analysis, the total smoking period (${\beta}$=0.042, P=0.001) and urinary cotinine levels (${\beta}$=0.234, P<0.001) were positively associated with nicotine dependence, whereas an inverse association was observed between highest education levels (>16 years) and nicotine dependence (${\beta}$=-0.573, P=0.034). Conclusions: The results of this study support the validity of using urinary cotinine levels for assessment of nicotine dependence in active smokers.

Objectives: This study assessed the associations between socio-demographic, health and wellbeing variables (independent variables) and daily smoking, attempts to quit smoking, and agreement with smoking ban (dependent variables). Methods: Data from 3,706 undergraduate students were collected from seven universities in England, Wales, and Northern Ireland using a standardised questionnaire. Results: About 15.8% of the whole sample reported daily smoking, while 12% were occasional smokers. Smoking was significantly more prevalent among males, but the difference was due to a higher rate of occasional smokers. About every second smoker (55%) had attempted to quit smoking. Almost 45% of the whole sample agreed or strongly agreed with implementing a total smoking ban on campus. Daily smoking was more likely among students with not sufficient income, students whose fathers had at least a bachelor degree; and, students who reported binge drinking. Conversely, daily smoking was less likely among students who rated their health as very good/ excellent, those who ate ${\geq}5$ portions of fruit or vegetables, and those who had never taken illicit drugs. Previous attempt/s to quit smoking were more likely among students who have never taken illicit drugs and those who agreed with a total smoking ban; and less likely among those with not sufficient income. Daily smokers were less likely to report quit attempts as compared to occasional smokers. An agreement with smoking ban was more likely among students who rated their health as very good/excellent, those who ate ${\geq}5$ portions of fruit or vegetables daily, and those who had never taken illicit drugs, but less likely among daily smokers. Conclusion: Favourable health practices and positive attitudes towards smoking ban were associated with each other. Interventions would need to comprise multi-component programmes that do not solely focus on smoking prevention/cessation, but also on other health promoting practices as well.

Objectives: Lung cancer is a major public health problem and one of the most costly illnesses. The study aimed to estimate the economic burden of lung cancer in Iran in 2014. Methods: A cross-sectional study was conducted to estimate the direct and indirect costs for patients with lung cancer using a prevalence-based approach. A human capital approach was employed to estimate the indirect costs. Data were obtained from several sources such as through patient interview using structured questionnaire, medical records, the GLOBOCAN databases, the Iranian Statistical Center, the Iranian Ministry of Cooperation, Labor and Social Welfare, and the Institute for Health Metrics and Evaluation (IHME). Results: The economic burden of lung cancer in Iran in the year 2014 was 3,225,998,555,090 IR. The main components of the cost were associated with mortality (81.9 %) and hospitalization (7.6 %). The costs of direct medical care, non-medical aspects, patient time, and mortality accounted for 10.8%, 2.7%, 4.5%, and 81.5% of the total cost, respectively. Conclusion: Findings from this study indicated that the economic burden of lung cancer is substantial both to Iran's health system and to society as a whole. Early diagnosis, strengthening cancer prevention, implementing new cancer therapy and medical technology, and effective smoking-cessation interventions could offset some of the costs associated with lung cancer in Iran.
