This research was conducted to understand the different circumstances for wearing shirts by adult males aged 20-39, and to provide this basic information to the shirt industry prior to developing new functional men's shirts. A total of 345 respondents participated in the survey. Most of questionnaire, frequency, mean and standard deviation were calculated and the differences between the 20s and 30s were analyzed by t-test or ${\chi}^2$ test. The results of the survey are as follows. Grading the satisfaction degree of their body parts, the respondents were relatively unsatisfied with their height, weight, and waist, abdominal and hip circumferences. Majority preferred department stores, discount stores and outlets for purchasing shirts. Many have never owned tailored shirts - men in 20's had less experience with tailoring than men in 30's. The foremost selection criterion for purchasing shirts was fit -during purchase, men in their 20's considered fit more important than men in their 30's. The most preferred unbuttoning of the top button when wearing shirts. For favored collar shapes with one button unbuttoned, the most valued collar angle and style was V-neck shape when unbuttoned, low collar band, collar with unopened collar, and stiff collars. Most shirt designs and details included slim fit, no dart in the front and one dart on the back. Men in 20's more preferred the no dart in the front and one tuck on the back, as compared to men in 30's. On the other hand, men in their 30's preferred one dart shirts than men in 20's. Regarding shirt bands and cuffs, one button and regular collar and one button cuffs with round angle design, were the most preferred, respectively.

The aim of this study was to verify the suitability or unsuitability of Korean body types by measuring the opening force criteria of an air pressurized access door to a smoke control zone. The opening force criteria were verified by comparing the NFSC 501A, NFPA 92A and BS-EN 12101-6 based on the body standards information from the Korean Agency for Technology and Standards. When measuring the opening forces, the posture of the body should be standing upright and pushing an access door with the right hand, which is a criterion for designing doors. As a result of analyzing the actual measurement results, the pushing force of men and women in their 30's was the maximum value and the forces in those in their 60's was the minimum value. In addition, the deviations in the pushing forces varied considerably. As a result of comparing the NFSC 501A, the men showed lower values than the criteria in every gender and age variable except for the 20's, 30's and 50's variable. A comparison of the criteria of NFPA 92A showed that the mean of the measured values from every gender and age was also lower than the criteria. In addition, when comparing the criteria of BS-EN 12101-6, it was found that the men in every age variable were higher than the criteria. On the other hand, the women in every age variable were lower than the criteria. Therefore, considering the Korean body type against the Western body type, it was decided that the opening force of an access door to a smoke control area to make a downward adjustment should be 110 N in the local criteria. Furthermore, the criteria should consider the characteristics of buildings and users because an optional application of the international standard is not necessarily suitable for local situations.

The purpose of this study is to investigate the factors affecting consumer resistance of smart watches, focusing on consumer groups. SPSS 19.0 was used to conduct a descriptive analysis and multi regression analysis of the data. This study is based on the questionnaire data of 407 consumers. The results of this study are as follows. First, the relative advantage was identified as a factor in reducing consumer resistance across all gender and age groups. Second, complexity has been identified as a factor that increases the consumer resistance of female consumers, and consumer groups in their 20s and 40s. Third, esthetics was found to reduce consumer resistance in men, women, and the consumer group in their 20s. Fourth, subjective norms were identified as a factor reducing consumer resistance in women and in consumer groups in their 20s and 30s. Fifth, the risk of privacy was identified as a factor in increasing consumer resistance in men and the consumer group in their 40s. The results of this study can be helpful to understand consumer resistance to smartwatches.

We analyzed 121 age estimation clients who had visited oral medicine clinic, Chonbuk National University Hospital, from January 2000 to December 2007 to evaluate its characters in Jeonllabuk-do. The obtained results were as follows : 1. There was distinct difference in sex distribution(Male : 58.7%, Female : 41.3%) and more than half percent(55.4%) was over 50's. 2. The difference between registered and alleged age was the most in more than 5 years, and most of them were over 50's. 3. There were more clients who wanted to increase their age than to decrease and was no prominent difference in sex. Age estimation clients who wanted to decrease their age were predominant under 10 years old and in 20's, and those wanted to increase were predominant in 10's and over 30's. 4. The most reasons to correct age were related to welfare benefit. The purpose of age estimation was different according to each age groups; welfare benefit was the most over 50's, occupation in 40's and 50's, friendship in 30's and 40's, sibling-related in 50's, employment in 10's and 20's. 5. Age was estimated by the attrition of permanent tooth and pulp/tooth ratio from 20 years, root apex closure for 10's and calcification of permanent tooth under 10 years old. In cases that were difficult to estimate by use of the attrition of permanent tooth and pulp/tooth ratio, age was estimated by missing time of permanent tooth and the change of mandibular angle with age. 6. The estimated ages were close to alleged age in 77.7% of clients but the rest(22.3%) was close to registered age.

In this study, a survey on the wearing satisfaction of commercial men's upper body correction underwear was conducted targeting mildly obese men in their twenties, and it was intended to suggest improvement points for the correction underwear. The product used for the study was Adapt's 95 PROBLEM, and 15 subjects were selected as males in their 20s with a BMI of 25-30 (mild obesity). As a result, men's awareness and interest in corrective underwear were low. In the wearing satisfaction survey, 74% of those who answered negatively that it was uncomfortable to wear and take off. In terms of pressure relief, 60% of those who felt the pressure was strong at the beginning, but as time passed, they got used to it and answered that there was no major inconvenience. However, with regard to digestion after a meal, 40% of the subjects felt that the pressure interfered with digestion. There were many deficiencies in terms of functionality, with more than half of those who responded negatively with regard to stuffiness and heat, and many negative opinions regarding sweat absorption and discharge. In the visual section, positive reaction was shown in chest, side waist and front waist correction, and among them, the front waist had the highest score. In conclusion, it seems that functional parts related to heat and sweat must be improved in consideration of the stuffiness and indigestion brought about by excessive pressure for men's upper body correction underwear.

This study examined the contribution of the risk factors that cause cardiovascular disease in Koreans. The subjects were 20,012 adults aged 30~74 years who were enrolled from the 2005~2013 Korean National Health and Nutrition Examination Survey, had filled the risk factors data, and had no cardiovascular disease history. Data analysis was conducted using SAS 9.3, and a weighted composite sample design analysis was performed. The contribution was obtained by applying a squared semi-partial correlation. As a result, they were higher in the order of age (63.9%), smoking (17.3%), systolic blood pressure (7.9%), diabetes (6.9%), antihypertensive medication use (3.0%), and BMI (0.9%) in men. In women, the contributions were in the order of age (54.1%), systolic blood pressure (23.5%), diabetes (13.6%), antihypertensive medication use (5.1%), smoking (3.1%), and BMI (0.6%%). According to age bracket analysis, smoking (51.8~33.7%) was the biggest risk factor, followed in order by age (26.6%) in their 30s and systolic blood pressure (17.3~21.0%) in those older than 40 years in men. In women, the systolic blood pressure (56.2~40.5%) was the main contributor to the risk factors, followed by age (24.0%) in their 30s and diabetes (13.6~32.6%) in those older than 40 years. The contribution of the income level was similar. Therefore, to prevent cardiovascular disease, various programs that reflect the contributions of the risk factors should be developed. Moreover, it is recommended to use the results shown in this study as basic data.
