This study conducted a survey on jean pants that targeted males in the 20s in order to select preferred brands for skinny jean pants. Preliminary data for the pattern development of skinny jean pants was presented through functionality evaluation, appearance evaluation and pattern analysis. The results were as follows. 1. The result of survey targeting males in the 20s to select the design and brand name of jean pants showed that skinny jean pants were selected as the most favorite type of jean pants to wear; in addition, non-brand products and brand names such as Uniqlo and Levi's were also preferred. 2. The result of functionality evaluation showed that L brand received a high score in all items except for items regarding the knee circumference and mid-thigh circumference, S brand received a high score as well as a low score, and N brand received a low score in general. The result of appearance evaluation showed that L brand for the waist height and waist circumference, N brand for the brand crotch circumference, posterior crotch length and knee circumference, and S brand and N brand for the length of pants were preferred. 3. The result of pattern measurements analysis from the result of functionality evaluation showed that L brand provided a large pattern measurement for the waist height, L brand provided less ease due to small pattern measurements for waist circumference; in addition, N brand for the knee circumference and mid-thigh circumference were preferred. 4. The analysis result shows that a ease of 5cm based on the belly band which is 3.5cm below the belt width is proper for the waist circumference when designing a skinny jean pant pattern and 4cm for the hip circumference and 32.5cm for the ease of crotch circumference are proper, -0.4-0cm for the ease of mid-thigh circumference and knee circumference in consideration of human body measurements; therefore, 80.1-80.5cm for inseam as the length from the crotch height to the leg length, 25.7cm for vertical hip length and 53.0cm for crotch length are proper.

This study is to understand the problems of cycle wear. Interviews and surveys were done to target male and female cyclists in order to understand the wearing conditions and satisfaction of cycle wearers. A total of 443 surveys were used to analyze demographic information, inconvenience and design preference. The average age of male respondents was 34.45 and females was 33.39. The majority were in their 20s and 30s. As for the bicycle riding time, 41.9% of females cycled in the morning and 39.5% cycled in the evening. For men, 44.7% of males cycled in the evening and 33.3% cycled in the morning. The number of cycle wear owned by female respondents were higher than men. Quick water-absorbent and drying properties were considered as important functionality in cycle wear for 87.8% of males and females. When wearing cycle wear, it was found that females felt more discomfort than males in terms of jersey top length. The study results indicated that cycle wear wearing conditions were different according to gender.

This study was carried out to offer basic data that can be used for outdoor wear production for active senior males, emerging as a new consumer bracket in the era of rapid aging. To this end, this study modified and complemented the patterns of outdoor jackets for active senior males based on existing outdoor jackets that received the most excellent evaluation. On the basis of the research outdoor wear wearing assessment results, this study confirmed those areas to be modified and proposed areas to be considered in manufacturing outdoor wear for this demographic. As a result of existing outdoor wear's wearing assessment, the jacket of brand B was shown to be the most excellent one. This study actually designed research outdoor wear patterns by modifying the problematic parts through the addition and subtraction of spare length or circumference in the sections where fit satisfaction was low by referring to the selected brands' patterns. The research outdoor wear was designed by referring to the preferred outdoor types and colors that were highlighted in the previous survey result of consumer wearing reality, based on the designs of the outdoor wear receiving the most excellent assessment in wearing assessment. Fabric that specially glued two-layered mesh that bonded the thin membrane of synthetic resin with polyester fabric was used as the material in this study. Wearing assessment was conducted by comparing the manufactured research outdoor wear and the existing outdoor wear selected as excellently assessed outdoor wear. Consequently, this study verified that the wearing fit of the research outdoor wear was more excellent in most items. This study proposed final patterns for outdoor jackets suitable for active senior males through the modification of several items that required improvements as per the wearing assessment of the research outdoor wear.

Background: Females generally have a lower pain and temporal summation threshold than men. However, the results of studies designed to evaluate gender differences in the thresholds of heat pain and the temporal summation have been inconsistent. Newly developed device, CHEPS (Contact Heat Evoked Potential Stimulation) model of PATHWAY, have superiority on its fast rise and return time in temperature. Therefore we investigated gender differences in heat pain and temporal summation threshold. Methods: Forty healthy volunteers (20 males and 20 females) were enrolled in this study. A thermode was applied to the volar side of each volunteer's left forearm and heat pain and the temporal summation threshold was then measured. The heat pain threshold was estimated using the staircase method by starting from $36^{\circ}C$ and then increasing the temperature in $0.5^{\circ}C$ increments. The temporal summation threshold was estimated by applying five successive stimulation of the same temperature starting at $2^{\circ}C$ lower than the heat pain threshold and then increasing the temperature in $0.5^{\circ}C$ increments. Results: The mean heat pain thresholds was found to be $41.63{\pm}1.63^{\circ}C$ for males and $41.60{\pm}1.84^{\circ}C$ for females and the temporal summation thresholds were found to be $40.83{\pm}1.64^{\circ}C$ for males and $40.77{\pm}1.93^{\circ}C$ for females. The differences between males and females were not statistically significant. Conclusions: The result of this study suggested that there are no gender differences in heat pain and temporal summation threshold.

This study aimed to investigate the perceptions and preferences of foreigners residing in Korea towards K-fashion. It sought to provide suggestions for the future development of K-fashion targeting this growing demographic. The results revealed that the longer foreigners had lived in Korea, the more positively they rated Korean fashion, shopping, and culture. The majority of foreigners purchased K-fashion items online, with popular choices including T-shirts, jackets, shirts, and jeans. Both men and women identified shoulders as a common problematic area when wearing clothing, with some issues also reported in the lumbar region. In terms of preferences, younger males (teens and twenties) were more inclined towards fads and celebrity wear compared to older males (thirties and forties). Similarly, younger females (teens and twenties) showed a higher preference for functionality and celebrity wear compared to older females (thirties and forties). These findings suggest that men tend to prioritize aesthetic factors when choosing K-fashion, while women prioritize practical considerations. To better cater to foreign consumers, suggestions for the development of K-fashion include promoting it through K-pop stars, considering dimensions related to foreigners' shoulders when designing top items, diversifying colors, sizes, and patterns, and providing English versions of online shopping platforms.

This study was carried out to investigate the body weight controls and eating disorders of university students in Gunsan. The subject of the present study included 229 male students (53.8%) and 197 female students (46.2%), totalling 426 students from Kunsan University. The subjects consisted of 56 underweight (13.1%), 265 with normal weight (62.2%), and 105 overweight (24.6%). Especially, in females, 20.8% of them were underweight, which is 6.6% higher than males, showing a significant difference (p<0.001). Regarding body image, 21.8% of the males thought they were fat, while 40.6% of the females thought they were fat. Regarding the perceived body type, shown in the difference between their own size and the ideal size, males recorded 0.03, while females recorded 1.75, showing a major significant difference (p<0.001). Regarding body satisfaction, 33.2% of the males were unsatisfied, while 52.8% of the females were unsatisfied (p<0.001). The social expectations of the male subjects' sizes and weights recorded 2.04, while that of females recorded -2.51, showing that people's opinions expected the female subjects' bodies to be thinner (p<0.001). Additionally, the social expectation of the subjects' weight control recorded an average of 15.22 (13.92 for males, 16.73 for females), showing that the female subjects' felt that people's opinions wished them to lose their weight (p<0.001). Regarding the recognition on weight control, interested males were 49.4%, while interested females were 86.8%, showing the females superior rate (p<0.001). The beliefs in relation to weight control recorded an average of 62.01, with the score of females of 67.89 being significantly higher than that of males which was 56.96. The subjects showed a relatively positive response towards weight control (p<0.001). EAT-26 score was employed to determine the eating attitudes in relation to gender. Here, the final score of males was 15.46, which was significantly lower than that of females, which was 22.21 (p<0.001). Furthermore, regarding the score of eating attitudes in relation to obesity index, the eating disorder scale scores on the questions related to bulimia and diets to lose weight as weight increases were high. However, the eating disorder scale score on oral control, which actually controls food, was low. To control the expansion of excessive weight control attempts and their side effects, the recognition of the students' body types needs to be corrected, and nutrition education programs on eating habits and eating disorders to foster proper weight loss are deemed necessary.

The purpose of this study was to characterize and determine variances of speaking fundamental frequency and vocal intensity depending on gender and three utterance conditions (spontaneous speech, reading, and counting). A total of 65 undergraduate students (32 male students, 33 female students) attending universities in Daegu, South Korea participated in this study. The subjects were all in their 20s. This study used KayPENTAX's Visi-Pitch IV (Model 3950) to measure the variances of speaking fundamental frequency (SFF0) and vocal intensity (VI). As a result, this study came to the following conclusions. First, it was found that both males and females showed no significant difference in SFF0 and vocal intensity among three utterance conditions. Second, this study sought to analyze differences in the variances of SFF0 between males and females. As a result, it was found that females showed significantly higher levels of four measured variances (SFF0 $SD^{**}$, SFF0 $range^{***}$, Min $SFF0^{***}$ and Max $SFF0^{***}$) than males on spontaneous speech. However, it was found that there was no significant difference between males and females in SFF0 range on reading or in SFF0 SD and SFF0 range on counting. It was found that there was no significant difference between males and females in the level of measured variances of vocal intensity depending on utterance conditions. Finally, this study made a comparison and analysis on differences in the variances of SFF0 and vocal intensity among utterance conditions. As a result, it was found that all the measured variances of SFF0 in males were most significantly reduced depending upon spontaneous speech which was followed by reading and counting respectively (SFF0 SD: p<.001, SFF0 range: p<.05, Max SFF0: p<.05). Females however, show no significant difference in the measured variances of SFF0 depending upon three utterance conditions. It was also found that the measured variances of vocal intensity in females were most significantly reduced depending on spontaneous speech that was followed by reading and counting (VI SD: p<.001, VI range: p<.001, Min VI: p<.01 Max VI: p<.05), while males showed no significant difference in the measured variances of vocal intensity depending on three utterance conditions. In sum, these findings suggest that variances of SFF0 in males are affected by three utterance conditions, while variances of vocal intensity in females are affected by three utterance conditions.

This study compared activity factor. predicted resting metabolic rate (RMR), and nutrient intakes between athletic and non-athletic high school students in Gangwon-do. Fifty soccer players (30 males and 20 females; mean ages 16.7${\pm}$1.0 years and 16.4${\pm}$1.1 years. respectively) and 50 non-athletic (30 males and 20 females: mean ages 17.5${\pm}$0.4 years and 16.4${\pm}$1.1 years respectively) high school students were included. Anthropometric measurements included: weight and height. triceps skinfold, mid-ann circumference, and body fat. Prediction equations consisted of those from the Harris-Benedict. FAO/WHO/VNU, IMNA, Cunningham, Mifflin et al., and Owen et al. A one-day activity diary was collected by interview, and the 24-hour recall method was used to analyze nutrient intakes of subjects. The activity factors of the male and female athletic groups (2.23 and 2.16, respectively) were significantly higher than those (1.52 and 1.46, respectively) of the non-athletic group. There was only a significant difference in RMR by use of the Cunningham's equation between two groups. For the males. almost all nutrient intakes of the athletic group (except carbohydrate, iron, vitamin $B_1$, $B_6$, and niacin) of athletic group were significantly higher than those of the non-athletic group. The female athletic group showed significantly higher nutrient intakes with the exception of most vitamins. These results suggest that assessments of energy balance between energy intake and energy expenditure by employing RMR and activity factors would be useful to prevent and treat obesity in high school athletes. In addition, the Cunningham's equation would be appropriate for predicting their energy needs.

We investigated the changes in plasma sex steroid hormones, testosterone (T), estradiol-$17{\beta}$ ($E_2$), 17,$20{\beta}$-dihydroxy-4-pregnen-3-one ($17{\alpha}20{\beta}P$), 11-ketotestosterone (11KT) and cortisol levels from ribbed gunnel, Dictyosoma burgeri in associated with annual reproductive cycle. The gonadosomatic index (GSI) of females increased from November, peaked in February and decreased rapidly from March. The GSI of males also increased from November, peaked in January and then decreased gradually. In females, $E_2$ levels increased and remained high from December to February. The levels of T showed a similar tendency and correlated ($r_s$=0.898, p<0.01) with $E_2$ levels. The levels of $17{\alpha}20{\beta}P$ increased rapidly in February ($4.78{\pm}1.01ng/ml$) and peaked in July ($5.08{\pm}0.65ng/ml$). Cortisol level was peaked in March and correlated with $17{\alpha}20{\beta}P$ levels ($r_s$=0.696, p<0.01). In males, the levels of T was peaked in January and then decreased rapidly. The levels of 11KT were remained high from October to January. On the other hand, the levels of $17{\alpha}20{\beta}P$ fluctuated during reproductive cycle. These results suggest that plasma sex steroids in ribbed gunnels have annual periodicity, and that cortisol may involve in maturation of females.
