Background: Phosphodiesterase Type 5 Inhibitors (PDE5Is), which are prescription drug in South Korea, have been concerned about misuse, overuse and illegal provision of the drugs. This study was performed to investigate utilization and safety of illegal Phosphodiesterase Type 5 Inhibitors (PDE5Is), and related factors among South Korean men. Methods: A questionnaire survey was conducted from May to July in 2013 among 1,500 nationally representative general males using computer-assisted telephone interview (CATI). The questionnaire included the characteristics of population, the characteristics of PDE5Is use, the experience with the use of illegally obtained PDE5Is, and adverse events after PDE5Is use. Results: Among study population, the 1,015 (67.7%) men answered that they have used the illegally obtained PDE5Is. Younger age, single, lower frequency of PDE5Is use in a lifetime was associated with an increased use of illegally obtained PDE5Is. The men experienced adverse events after PDE5Is use is 528 (35.2%). The most common adverse event was mild to moderate hot flashes. Conclusion: We need to enhance awareness about the risk of illegally obtained PDE5Is use, especially in younger men and single. Proactive educations and public relations on safe use of PDE5Is for proper patients are needed.

The purpose of this study was to understand changes of the current young generation's lifestyle, aesthetic attitude for an appearance, and way of thinking by making a close investigation into metrosexual, the recent mode, and find out its cultural and social implications. As a method of the study, the literature and the Internet data were reviewed. Articles from newspapers, magazines and the Internet were chosen roughly from the year 2000 to now because metrosexual mode remarkably boomed before and after 2000. Books related to the theory on the mode in a costume culture were referred. Also, articles in daily newspapers which dealt with cultural and social issues were reviewed, fashion magazines for men such as Esquire and GQ showing the new trend in men's lifestyle and fashion were examined, and the Internet providing us the latest news from cultural and social topics to fashion trends were investigated. The backgrounds of the rise of metrosexual mode were a collapse of stereotypes in various fields, spread of lookism in a visual image period, extension of commercialism, and expansion of men's character casual trend. Metrosexual was defined as an urban male with a strong aesthetic sense who spends a great deal of time and money on his appearance and lifestyle. His fashion style was characterized by slim and flowing silhouette, feminine and luxurious materials such as transparent chiffon, silk and cotton with a light and soft touch, and a knitted wear with a flowing line, a wide variety of vivid and pastel colors, floral and geometric patterns, and the decorative details like lace, beads, embroidery, and fur. From spread of this mode, two cultural and social implications were extracted. Firstly, the current young generation's aesthetic standards for the perfect man changed from macho man to considerate man who had a good appearance and this suggested that a conventional sex role broke down. Secondly, men began to explore for their own identity escaping from traditionally standardized masculinity that they had been forced to follow.

Objectives: This study examined trends in inequality in cigarette smoking prevalence by income according to recent anti-smoking policies in Korea. Methods: The data used in this study were drawn from three nationally representative surveys, the Korea National Health and Nutrition Examination Survey, the Korea Community Health Survey, and the Social Survey of Statistics Korea. We calculated the age-standardized smoking prevalence, the slope index of inequality, and the relative index of inequality by income level as a socioeconomic position indicator. Results: Smoking prevalence among men decreased during the study period, but the downward trend became especially pronounced in 2015, when the tobacco price was substantially increased. Inequalities in cigarette smoking by income were evident in both genders over the study period in all three national surveys examined. Absolute inequality tended to decrease between 2014 and 2015 among men. Absolute and relative inequality by income decreased between 2008 and 2016 in women aged 30-59, except between 2014 and 2015. Conclusions: The recent anti-smoking policies in Korea resulted in a downward trend in smoking prevalence among men, but not in relative inequality, throughout the study period. Absolute inequality decreased over the study period among men aged 30-59. A more aggressive tax policy is warranted to further reduce socioeconomic inequalities in smoking in young adults in Korea.

This study tests the relation of various fashion-related features of young male consumers. Clothing involvement, fashion involvement, fashion innovativeness, impulsive buying, and brand loyalty have been considered as focal variables in understanding consumer attitudes & behaviors toward fashion. This study proposed hypotheses on the relationships among these variables and tests them with survey data from a convenient sample of male university students. A total 195 complete responses were obtained from young men between 18 and 27 years of age. The results are as follows. First, fashion involvement and clothing involvement significantly (+) affected fashion innovativeness, and fashion innovativeness also significantly (+) affected impulsive buying and brand loyalty. Second, impulsive buying insignificantly affected brand loyalty. Third, the groups of young men divided by the demographical variables partially showed meaningful differences in fashion-related variables of interest. This study investigates the relationships among various fashion variables that have been used as critical explaining variables for fashion attitudes and behaviors, especially for young male consumers.

Statistical differences between men and women are investigated for a total of eleven joint motions during level walking. Human locomotion which exhibits nonlinear dynamical behaviors is quantified by the chaos analysis. Time series of joint motions was obtained from gait experiments with ten young males and ten young females. Body motions were captured using eight video cameras, and the corresponding angular displacements of the neck and the upper body and lower extremity were computed by motion analysis software. The maximal Lyapunov exponents for eleven joints were calculated from attractors constructed and then were analyzed statistically by one-way ANOVA test to find any difference between the genders. This study shows that sexual differences in joint motions were statistically significant at the shoulder, knee and hip joints.

Purpose: To assess the possibility of using panoramic indices as an indicator of jaw osteoporosis. Methods: Mandibular cortical width (MCW), degree of mandibular alveolar bone resorption (ABR) and morphology of mandibular inferior cortex (MIC) on panoramic radiograph were used as panoramic indices. These panoramic indices were compared with bone mineral density (BMD) of lumbar (L1-L4) and femoral neck measured by dual energy X-ray absorptiometry. We also compared MCW and ABR of young men with those of postmenopausal women. Results : There was a significant correlation between ABR and BMD of lumbar and femoral neck. And also significant correlation between MIC and BMD of lumbar and femoral neck. ANOVA test of BMD of lumbar and femoral neck showed significant differences according to morphologic classification of inferior cortex. There was significant difference in MCW and ABR between young men and postmenopausal women. Conclusion: Our results suggested that ABR and MIC on panoramic radiograph could be reliable in screening of osteoporosis.

The purpose of this study is to compare menu patterns by sex and age (3-6, 7-12, 13-19, 20-29, 30-49, 50-64, 65 over years old) between the 1998 and 2001 National Health and Nutrition Surveys of Korea. Frequently consumed menu patterns were investigated using the 24-hour recall data for 19,809 subjects (1998:10,102; 2001:9,707). To analyze patterns, dishes were classified into 29 categories by cooking method (KHIDI 2003). The results are as follows: the most frequent menu patterns were "rice+soup+kimchi" and "rice+stew+kimchi" in both men and women in both 1998 and 2001. Intake frequency of these menu patterns, a traditional Korean menu pattern, was higher with increased age. Intake frequency of "noodles" and "bread" increased in 2001 in both men and women, compared to 1998. And these patterns increased in the younger age groups, especially women in their twenties. Menu patterns of 2001 showed greater variety than those of 1998. Overall, the men's menu patterns showed more side dishes than those of women; intake frequencies of "seasoned vegetables", "stir-fried foods", and "grilled foods" were higher in men than in women. In short, so far the main menu pattern has been "rice-style" in both men and women, and in all age groups in Korea, whereas the Western menu pattern is increasing in younger age groups. The diet of 2001 showed more side dishes than that of the 1998 menu pattern; however, certain groups such as female and males in adolescents and young adults were still a simple menu pattern. Consequently, to make recommended menu patterns and nutrition education programs for Koreans should take into consideration sex and age.

The study was conducted to investigate how Korean men in their 20s and 30s perceive abortion. A cross-sectional survey was conducted. One hundred forty participants were selected from male adults in G city and J area. The inclusion criteria were as follows: (1) men were between 20 to 39 years old; (2) were able to read and understand Korean; (3) understood the purpose of the study; and (4) agreed voluntarily to participate in this study. A structured questionnaires were used as a study instrument, and included questions regarding subjects' general characteristics and their perception of abortion. Data were collected from March to June 2016. Descriptive statistics and Fisher exact test were used for analysis. 67.1% of participants responded that 'people can have abortion under some circumstances'. The results found that 'education about contraception (68.6%)' was widely regarding among the subjects as the best way to prevent abortion. There were also significant differences in their responses depending on a subject's some characteristics. Our results suggest that it is needed to offer education program about abortion for young men.

Sagittal split ramus osteotomy(SSRO) has been commonly performed in the mandibular prognathism. The previous studies of the mandibular anatomy for SSRO have mostly been used in dry skull without consideration of age, sex or jaw relationship of patients. This study was performed to evaluate the location of mandibular canal and the anatomy of ramus, such as the location of mandibular lingula and the ramal bone marrow, which were associated with SSRO procedures, in the patients with mandibular prognathism and normal young adults by using computerized tomographs(CT) and 3D images. The young adults at their twenties, who were considered to complete their skeletal growth, and seen in the Department of Orthodontics and Oral and Maxillofacial Surgery in Chonnam National University Hospital between March 2000 and May 2003, were selected. This study was performed in 30 patients (15men, 15women) who were diagnosed as skeletal class I normal relationship, and another 30 patients (15men, 15women) who were diagnosed as skeletal class III relationship upon clinical examination and lateral cephalometric radiographs. The patients were divided into 2 groups : Class I group, the patients who had skeletal class Ⅰ normal relationship(n=30, 15men, 15women), and Class III group, the patients who had skeletal class III relationship(n=30, 15men, 15women). Facial CT was taken in all patients, and pure 3D mandibular model was constructed by V-works version 4.0. The occlusal plane was designed by three points, such as the mesiobuccal cusp of both mandibular 1st molar and the incisal edge of the right mandibular central incisor, and used as a reference plane. Distances between the tip of mandibular lingula and the occlusal plane, the sigmoid notch, the anterior and the posterior borders of ramus were measured. The height of ramal bone marrow from the occlusal plane and the distance between mid-point of mandibular canal and the buccal or lingual cortex of the mandible in the 1st and 2nd molars were measured by V-works version 4.0. Distance(Li-OP) between the occlusal plane and the tip of mandibular lingula of Class III Group was longer than that of Class I Group in men(p<0.01), but there was no significant difference in women between both groups. Distance(Li-SN) between the sigmoid notch and the tip of mandibular ligula of Class III group was longer than that of Class I Group in men(p<0.05), but there was no significant difference in women between both groups. Distance(Li-RA) between the anterior border of ramus and the tip of mandibular lingula of Class III Group was shorter than that of Class I Group in men and women(p<0.01). Distance(Li-RP) between the posterior border of ramus and the tip of mandibular lingula of Class III Group was slightly shorter than that of Class I Group in men(p<0.05), but there was no significant difference in women between both groups. Distance(RA-RP) between the anterior and the posterior borders of ramus of Class III Group was shorter than that of Class I Group in men and women(p<0.01). Longer the distance(SN-AN) between the sigmoid notch and the antegonial notch was, longer the vertical ramal length above occlusal plane, higher the location of mandibular lingula, and shorter the antero-posterior ramal length were observed(p<0.01). Height of ramal bone marrow of Class III Group was higher than that of Class I Group in men and women(p<0.01). Distance between mandibular canal and buccal cortex of Class III Group in 1st and 2nd lower molars was shorter than that of Class I Group in men and women (p<0.05 in 1st lower molar in men, p<0.01 in others). These results indicate that there are some anatomical differences between the normal occlusal patients and the mandibular prognathic patients, such as the anterior-posterior length of ramus, the height of ramal bone marrow, and the location of mandibular canal.

Purpose: This study was done to compare demographic characteristics, comorbidity, and health habits of elders with mild cognitive impairment (MCI) and elders with cognitively normal function (CNF). Methods: Secondary data analysis was conducted using data from the Database of the Seoul Dementia Management Project for 5,773 adults age 60 and above. Results: The MCI group showed an older age distribution, but there was no significant education difference between the two groups. Elders with MCI had more diabetes and stroke than elders with CNF. In subgroups, the same findings were observed in women, but not in men. While more men with MCI had hypertension compared to men with CNF, there was no significant difference in hypertension between the two groups for women. Elders with MCI, men in particular, had a lower prevalence of obesity than men with CNF. MCI individuals did less exercise compared to individuals with CNF. While there were no significant differences in alcohol consumption and smoking between MCI and CNF groups, the over 80's subgroup with MCI reported more alcohol consumption. Conclusion: Findings from this study could be helpful in designing community-based dementia prevention programs and health policies to reduce the prevalence of dementia or related cognitive impairments.
