Trichomonas vaginalis, a causative agent of trichomoniasis, may trigger symptomatic or asymptomatic non-gonococcal urethritis and chronic prostatitis in men. Despite the availability of highly sensitive diagnostic tests, such as nucleic acid amplification tests, including PCR, few prospective studies present data on male T. vaginalis infection in South Korea. In the present study, the prevalence of T. vaginalis and associated clinical conditions were evaluated in 201 male patients from a primary care urology clinic in South Korea. The prevalence of T. vaginalis infection in our cohort was 4% (8/201) by PCR. T. vaginalis infection was common in men older than 40 years (median age, 52 years). Among the 8 Trichomonas-positive patients, 87.5% (7/8) had prostatic diseases, such as prostatitis and benign prostatic hyperplasia, and 25.0% (2/8) and 12.5% (1/8) were coinfected with Chlamydia trachomatis and Mycoplasma genitalium, respectively. Our results suggest that T. vaginalis infection is not rare in men attending primary care urology clinics in South Korea, especially in those older than 40 years, in whom it may explain the presence of prostatic disease. The possibility of T. vaginalis infection should be routinely considered in older male patients with prostatic diseases in South Korea.

Purpose: This study was conducted to investigate the prevalence and risk of gout in healthy workers. Methods: This cross-sectional analysis was conducted in 1,876 subjects (1,515 men and 361 women) enrolled in the Healthy Worker Cohort Study at Daegu, South Korea. Relationships between serum uric acid levels and independent risk factors were evaluated using multiple linear regression analysis after adjustment for covariates. Results: Among study participants, the prevalence of gout was 22.9% in men and 2.5% in women (based on a serum uric acid level >7.0 mg/dL for men and >6.0 mg/dL for women). Among men, increased ALT, GGT, total cholesterol, and triglycerides were associated with increased risk of gout (p<0.05) by multiple linear regression analysis; however, increased age and HDL-cholesterol/triglyceride ratio were associated with decreased risk of gout (p<0.05). In women, increased triglycerides were associated with increased risk of gout (p<0.05). Conclusion: Our findings suggest that increased triglycerides were significantly associated with the risk of gout in men and women. Moreover, a high HDL-cholesterol/triglyceride ratio in men may reduce the risk of gout.

본 연구는 징병제가 존재하고 한국과 사회적 역사적 유사성이 두드러지지만, 한국과는 달리 위계적 대학문화에 대한 증상이 거의 없는 대만과 대학생문화에 대한 양적 질적 비교를 병행하였다. 이런 비교조사와 분석을 통하여 한국대학의 위계적, 성차별적 군대문화의 현황을 좀 더 명확히 짚어내고 원인을 파악하려 노력하였다. 비교 연구 결과를 보면 대만의 대학문화는 한국보다 위계적이지 않고, 위계문화의 필요성에 대한 지지도가 낮았다. 폭력이나 단체기합등 군대문화적 요소는 주로 한국대학문화에서만 나타났고 남성중심적 술문화와 성매매문화의 지배력도 한국에서 더 강한 것으로 확인되었다. 대만과 한국의 대학문화의 이러한 차이를 낳는 사회 역사적 원인을 살펴보면 대만이 한국보다 위계적 집단주의 문화의 근거이고 원동력이라고 할 수 있는 국가주의적, 군사주의적 국민의 내적 동의나 뿌리가 약하다는 점을 들 수 있다. 대만 대학문화가 상대적으로 덜 위계적인 가장 중요한 직접적 원인은 징병시기에서 찾아볼 수 있다. 한국은 일반적으로 재학중 군대를 다녀오지만 대만은 대학을 마친 후 군대를 다녀오는 것이 일반적이다. 한국의 대학문화에서 군유경험자는 폭력성이나 위계문화 또는 술문화에 큰 영향력을 행사하는 존재로 확인되었다.

Objectives: This study attempted to explore the aging phenomena that now characterize much of Korean society, and assessed issues associated with the life satisfaction experienced during the process of aging. Methods: By employing the National Survey on the State of Life and the Desire for Welfare of the Elderly, 2004 in South Korea this study attempted to identify the factors that determine subjective life satisfaction among the elderly. The data utilized herein consisted of 3278 elderly people aged 65 years or older, from 9308 households. Results: The results of analysis from the final model after the introduction of 19 variables in 8 factors showed statistically similar explanatory power in men (adj. $R^2=0.320$) and in women (adj. $R^2=0.346$). We found that economic condition was the most influential factor in both men (B = 0.278) and women (B = 0.336) except perceived health condition variables. The second most influential variable in life satisfaction was health checkups in men (B = 0.128) and degree of nutritional diet in women (B = 0.145). Those who had experience with chronic diseases also reported significantly lower perceived life satisfaction and this was particularly true of women. Conclusions: The aging society requires an understanding of the lives of elderly individuals. This study explored factors associated with life satisfaction in old age by using a life satisfaction model. The success of an aging society begins with an accurate understanding of the elderly, and thus political attention will need to be focused on this matter.

This study compares marital satisfaction between male and female rural migrants and explores the effects of characteristics of rural migrants and family values on marital satisfaction. Data were collected using a structured questionnaire. The survey included 483 migrants living in rural communities of North Jeolla Province and South Jeolla Province. Data were analyzed using descriptive statistics, cross tables, the t-test, correlations, and a hierarchical regression analysis using SPSS 21.0. According to the results, marital satisfaction was higher in men than in women. In addition, the effects of characteristics of rural migrants and family values on marital satisfaction were greater in men than in women. The major determinant of marital satisfaction in men was economical preparation, whereas that in women was family values. Economical preparation for rural living was more important for men, and the sufficient understanding and internalization of rural living was more important for women. In particular, family values represented the main variable between men and women in terms of marital satisfaction. These results suggest that family relationships may be the most important factor influencing rural migrants' marital satisfaction and that spousal relationships may be the core factor influencing family relationships.

Objectives: The aim of this study was to measure income differences in smoking prevalence at the district level and to investigate correlations among area deprivation, smoking prevalence, and income differences in smoking prevalence, stratified by urbanity. Methods: Data were pooled from the Community Health Survey data of South Korea between 2008 and 2014. The age-standardized prevalence of smoking and its interquintile income differences were calculated. We conducted correlation analyses to investigate the association of the deprivation index with smoking prevalence and interquintile differences in smoking prevalence. Results: Across 245 districts, the median prevalence of smoking in men was 45.9% (95% confidence interval [CI], 43.4 to 48.5%), with an interquartile range (IQR) of 4.6% points. In women, the median prevalence was 3.0% (95% CI, 2.4 to 3.6%) and IQR was 1.6% points. The median interquintile difference in smoking prevalence was 7.4% points (95% CI, 1.6 to 13.2% points) in men and 2.7% points (95% CI, 0.5 to 4.9% points) in women. The correlation coefficients for the association between the deprivation index and smoking prevalence was 0.58, 0.15, -0.22 in metropolitan, urban, and rural areas, respectively, among men, and 0.54, -0.33, -0.43 among women. No meaningful correlation was found between area deprivation and interquintile difference in smoking prevalence. The correlation between smoking prevalence and interquintile difference in smoking prevalence was more evident in women than in men. Conclusions: This study provides evidence of geographical variations in smoking prevalence and interquintile difference in smoking prevalence. Neither smoking prevalence nor the deprivation index was closely correlated with interquintile income difference in smoking prevalence. Measuring inequalities in smoking prevalence is crucial to developing policies aimed at reducing inequalities in smoking.

The aim of this study was to examine the use of such dietary supplementation practices, opinions, taking period for dietary supplement, and among elite Judoists varying in age and gender. Subjects were recruited from Korea National Team Judoists in elite athlete training centers (Taenuing in Seoul, Korea and surrounding area), a total of 223 elite Judoists (2003y n=34, 2005y n=41, 2006y n=101, 2007y n=30, 2008y n=17). Data were collected from personal interviews with Judoists who participated at the Olympic games, Asian game and World Championship game since 2003-2008. Elite Judoists representing mean age of 2003y (men: 23.5±2.7, women: 22.6±2.4), 2005y (men: 23.4±2.6, women: 22.5±2.3), 2006y (men: 20.3±3.2, women: 21.9±2.4), 2007y (men: 25.3±2.6, women: 22.5±2.8) and 2008y (men: 23.9±3.9) completed a validated questionnaire assessing dietary supplementation practices and opinions. Older Judoists were significantly more likely to report greater dietary supplementation usage; to be advised by oneself; health food store and pharmacy retailers; to decrease taking period days per week and past 6 month. Relative to gender, significant differences were observed for the types of dietary supplementation reported; supplementation practice trend; reasons for dietary supplementation use.

The study aimed to evaluate the appearance of the men's work clothes jumpers developed to suggest the prototype work clothes jumper patterns by using the 3-D clothing simulation technology. The 3-D simulated clothing images considered the upper body features of men in the age range between 20 and 59 in South Korea. A questionnaire survey conducted previously suggested a basic jumper style with shirt collar and snap opening cuffs for the heavy industry workers; and discomforting parts of the work clothes jumper of the subject workers have been referred to for the experimental jumper appearance test. Besides, defining the measurements of men's upper bodies enabled to generate the men's 3-D virtual models representing each age group's average body feature. The significant body measurement factors for men's 3-D body modeling and jumper pattern-making were stature for the height factor; chest, waist and hip circumferences for the circumference factor; waist back, hip and arm lengths and interscye front/back for the length factor; and back neck breadth for the breadth factor and armscye and scye depths for the depth factor. The men's body measurements of 30's were implemented to three experimental jumper pattern-making methods, i.e. the 1st method using the relations based on stature and chest circumference; the 2nd method using the direct body measurements; and the 3rd method adopting the maximum ease amount of given body measurements whether relations or direct measurements except the direct measurement of scye depth. A comparison among the three experimental jumpers' simulated images highlighted that the appropriate ease amount of the jumper gained higher scores in terms of the jumpers' front, side, back and sleeve parts and the total silhouettes. Therefore the 3rd experimental jumper was finally selected for the heavy industry workers.

Objectives: It is necessary to examine groups carrying out sexually risky behavior because the prevalence of sexually transmitted diseases (STDs) is high among them. In this study, the prevalence of STDs among homosexuals and sexbuying men in South Korea was investigated, along with their sexual risk factors. Methods: Men who have sex with men (MSMs, n=108) were recruited in Seoul and Busan by applying the time location sampling method, while sex-buying men (n=118) were recruited from a john school in Gyeonggi province, the suburbs of Seoul. Dependent variables included past or present infection with syphilis, Chlamydia, gonorrhea, and human immunodeficiency virus. Independent variables included health behavior, social support, sexual behavior, and safe sex. Results: It was found that when the MSMs were non-drunk while having sexual intercourse (odds ratio [OR], 0.132), they showed a higher STD infection rate when they had a higher number of anal sex partners (OR, 5.872), rarely used condoms (OR, 1.980), had lower self-efficacy (OR, 0.229), and were more anxious about becoming infected with an STD (OR, 3.723). However, the men who paid for sex showed high STD infections when they had more sex partners (OR, 2.286) and lower education levels (OR, 3.028). Conclusions: STD infections among the two groups were high when they were engaged with many sex partners and not having protected sex. In other words, there was a gap in risky sex behavior within such groups, which was significantly related to the possibility of developing an STD. Therefore, the preventive intervention against STDs for these groups needs to be expanded to include management of sex behaviors.

Although early studies suggested that bladder cancer (BCa) is more prevalent in men than in women, muscle-invasive rates are higher in women than in men, suggesting that sex hormones might play important roles in different stages of BCa progression. In this work, we found that estrogen receptor beta ($ER{\beta}$) could increase BCa cell proliferation and invasion via alteration of miR-92a-mediated DAB2IP (DOC-2/DAB2 interacting protein) signals and that blocking miR-92a expression with an inhibitor could partially reverse $ER{\beta}$-enhanced BCa cell growth and invasion. Further mechanism dissection found that $ER{\beta}$ could increase miR-92a expression at the transcriptional level via binding to the estrogen-response-element (ERE) on the 5' promoter region of its host gene C13orf25. The $ER{\beta}$ up-regulated miR-92a could decrease DAB2IP tumor suppressor expression via binding to the miR-92a binding site located on the DAB2IP 3' UTR. Preclinical studies using an in vivo mouse model also confirmed that targeting this newly identified $ER{\beta}$/miR-92a/DAB2IP signal pathway with small molecules could suppress BCa progression. Together, these results might aid in the development of new therapies via targeting of this $ER{\beta}$-mediated signal pathway to better suppress BCa progression.
