And it is very variety in each population statistics factors the differences of associate design visual effect which considering the difference of sex and age group, numbers of button, a figure and material pattern. Firstly, look into the associate design visual effect by sex and button number. In men's group, the style with three buttons was the most attractive and that with two buttons was the least attractive. In 50's group, the style with two buttons was the least attractive and those with 1.3 and 4 buttons were a little attractive. Secondly, in the difference of associate design with sex and shape, men's group was considered that standard type was the most attractive shape, women's group was thought that lean and standard types were the most attractive shape. So we can know that the attractive shape is different with sex. In the difference of association design with age and shape, 20's considered that standard type was the most modernistic and fat type was the least modernistic. 30's considered that lean type was the most modernistic and 50's thought that fat type and standard type were the most modernistic. Thirdly, see the sex and material pattern. In familarity, men's group considered that stripe pattern was more familiar than checks and plain patterns. And they considered that striped pattern and plain was more manly than checks. In sex and material pattern, 20's thought that plain was the most attractive, stripe was the next, and checks was not attractive. 40's estimated that plain and stripe were more attractive than checks. 50's judged that stripe was the most attractive material. Thus. the attraction is different with ages and material patterns.

This study examines the influence of fashion accessories on how men of different ages are perceived, as well as how the social values of the perceiver affect the image evaluation process. For the purpose of this study, men's accessories were limited to glasses, ties, and hats. A quasi-experiment was conducted in which 358 female university students in Seoul examined two men, one in his 30s and the other in his 60s. The social value included materialism and hedonism with higher and lower group. Factor analysis revealed three main factors with regard to men's image based on age and accessories: professionalism, morality, and preference. The findings indicated that wearing accessories can affect how men are perceived, and the perceivers' social values are at play throughout the process. Glasses enhanced a professional image in men, while ties amplified professionalism and morality. Morality and preference for the older man were heightened when he wore a fedora and a hunting cap. Taking social values into account, perceivers with a higher level of materialism associated a man with a navy blue tie more strongly with professionalism. Perceivers who possessed more hedonistic traits preferred a man wearing a cap. The subjects considered the man in his 60s as having a higher level of professionalism when he wore casual hats such as a cap or a cloche. The results of this study suggest that social values such as materialism and hedonism play a part in how people perceive men wearing accessories.

This study was designed to investigate the median nerve cross-sectional area of the upper extremity which is the main cause of CTS in the 20s and 30s. The median nerve cross-sectional area (MNC-area) of each part of the upper limb was measured in healthy 20s and 30s females and males without neurological diseases or other diseases. This MNC-area was compared with the hand, wrist, finger, and other body indexes. The research group was divided into 20s female and male groups, and the 30s were also divided into female and male groups. In the comparison between the ages, the hand, and wrist configurations in the 30s were significantly higher than those of the 20s. The mean median nerve cross-sectional area was significantly larger in the male group than in the female group in both 20s and 30s, and it was larger in both men and women than in the 20s. Hand and wrist configurations were also positively correlated with the median nerve cross-sectional area in both 20s and 30s. The median values of hand ratio and wrist ratio were 2.26 and 0.65, respectively. This median value of hand ratio was inversely correlated with the median nerve cross-sectional area. The median nerve cross-area of the 20s was 6.88~7.38 ㎟ in the male group and 5.69~6.99 ㎟ in the female group, respectively. The median nerve cross-area of the 30s was 6.32~8.89 ㎟ in the male group and 6.15~7.17 ㎟ in the female group, respectively. The mean median nerve cross-sectional area was positively correlated with body mass index in both groups. Most of the variables were higher in their 30s than in their 20s.

This study used raw data from the survey on the actual social and economic conditions of the youth of 2016. Among the 2,534 subjects, 904 unmarried workers in their 20s and 30s were included in the analysis. Dependent variables were marriage needs, and independent variables were age, sex, height, weight, education level, monthly income, parents' economic level, and health-related variables were self-rate health, stress, regular exercise, and life satisfaction included. Statistical analysis was performed binominal logistic regression analysis. In results, there were no factors influencing perception of marriage needs in 20s men, and Education was a predictor in 20s women. In 30s men, the more regular exercise, the less the monthly income, the more positive the perception of marriage needs was. In the 30s women, the better the self-rate health, the more positive the perception of marriage needs was. These findings suggest that health may affect the marriage perception of 30s unmarried workers.

The purpose of this study was to investigate the relevance of gender, age, and BMI (Body Mass Index) to changes in the urinary creatinine concentration in Korean adults. We recruited and surveyed 2,156 persons $\geq$20 years of age from 98 districts across the country, and collected urine samples for analyzing the creatinine concentration. Participants were 41.6% men and 58.4% women. In terms of age, the percentage of the population in their 20's and $\geq$60 years of age was relatively similar, with 13.6% and 17.8%, respectively, while the percentages in their 30's, 40's and 50's were also relatively similar, with 22.0%, 24.0%, and 22.6%, respectively. The proportion of participants in their 20's and 30's who were underweight (according to the BMI) was 25% and 19.2%, respectively, but only 6.2~6.4% of those $\geq$40 years of age were underweight. This showed that the underweight proportion in elder generations was less than that in younger generations. Meanwhile, the proportion who were overweight was 13.7%, 18.8%, 28.6%, 27.9%, 32.0% when the participants were in their 20's, 30's, 40's, 50's and $\geq$60 years of age, respectively (p<0.000). This showed that the overweight proportion increased along with increasing age. The overall urinary creatinine concentration was 10 mg/dl (arithmetic mean: AM), and 92.2 mg/dl (geometric mean: GM). The urinary creatinine concentration in men (132.6 mg/dl, AM) was significantly higher than that in women (93.3 mg/dl, AM (p<0.000)). Showing a similar trend in men and women, urinary creatinine concentrations were highest when the participants were in their 20's (135.6 mg/dl, AM), and tended to decrease with increasing age. Urinary creatinine concentrations in overweight and obese subjects (AM of 117.9 mg/dl and 118.0 mg/dl, respectively) were significantly higher than in other groups, and this trend was similar in men and women. In conclusion, we found that urinary concentrations were significantly affected by gender, age, and BMI, and that care should therefore be exercised when correcting urinary metabolites according to the urinary creatinine concentration.

The purpose of this study was to explore the relation of BMI, smoking and drinking with biomedical parameters in 20s and 30s men. This was a retrospective exploratory study and the subjects were 603 men who participated in health check-up for clinical trial at a tertiary hospital between October 2006 and June 2011. RBC, hemoglobin(Hb), hematocrit(Hct), triglyceride(TG), uric acid(UA), ALT in obese group were significantly higher than those of normal weight group. WBC and Hb in smokers were significantly higher than those of nonsmokers, protein in smokers was significantly lower than that of nonsmokers. Platelet in moderate smokers who smoke 10~19 cigarettes a day was significantly higher than that of nonsmokers and light smokers who smoke below 10 cigarettes a day, albumin in moderate smokers was significantly lower than that of nonsmokers and light smokers. TG in moderate smokers was significantly higher than that of nonsmokers, and blood glucose(BG) in moderate smokers was significantly lower than that of nonsmokers. AST and ALT in drinkers who drink over 10g a day were significantly higher than those of nondrinkers. In regression, BMI was significant factors of increasing RBC, Hb, Hct, total cholesterol(TC), TG, BG, UA, AST and ALT. Smoking amount was significant factors of increasing WBC, Hb, Hct and TG, and was significant factors of decreasing BG and Ca. Smoking amount was significant factors of increasing TC, AST and ALT, and was significant factors of decreasing WBC. In conclusion, there was significant relations of BMI, smoking, and drinking with biomedical parameters such as Hb, TC, TG, and ALT in young-aged men. Therefore, practice of healthy lifestyle activities to include preventing obesity and heavy drinking, and quitting smoking needs to the 20s and 30s men for preventing lifestyle disease.
