To do this study, we produced cooling vest newly. Rectal temperature was ascended approximately from 37.2$^{\circ}C$ to 38.05$^{\circ}C$ in lab, but wearing cooling vest, the temperature was descended 0.2 while wearing developed product compare with existing product. Mean skin temperature which was showed distribution from 32.8∼36.5$^{\circ}C$, it was descended 1.0∼1.1$^{\circ}C$, while wearing cooling vest and comparing with existing product, wearing developed product was lower 0.5$^{\circ}C$, While wearing developed product, it was found that they had lower tendency than exiting product. Specifically in case of temperature within clothing(chest) 0.2∼2.0$^{\circ}C$ in case of humidity within clothing 2∼8% RH. Facts from above we confirmed that clothing microclimate had been improved and space was happened between body and garment in order to control. In subjective sensation, existing product made negative response during experiment period from participants, but developed product was nearing to comfortable area.

This study was performed to analyze the wearing practice and the purchasing characteristics of jeans in order to offer basic data to produce superior jeans made of denim with small flexibility and to improve the wearing comfort. The questionnaire were 236 Korean women from the age of 10th to 50th. For data analysis, descriptive analysis and crosstabs were used. The results were as follows, in the purchasing characteristics, when the women of 10th to 30th decided to purchase jeans they considered fashion, design and price rather than wearing comfort. But the women of 40th to 50th considered that wearing comfort is the most important factor. The 10th is found the best preferred jean is wide straight style, the 20th is straight style, the 30th is boots cut style and the 40th to 50th is straight style. In wearing practice, there was a difference among age groups on the region that felt uncomfortable when wearing jeans. As the age increases, the abdomen size also increases. Most people answered that they mend jeans after purchase for length, without any relation with age. The reason why consumers prefer jeans with middle length between the crotch and waist and also purchase jeans with a short length is because they look refined and neat. This informs us that the short length between the crotch and waist does not match with ease and comfort, which are the images of jeans in the past. Recently premium jean brands are competing to show Low Rise Jeans, which seems like a Premium Jean=Low Rise Jean formula is created. Some manufacture companies are recklessly copying foreign designs that does not fit Korean's body shape. However, as mentioned in this study results, there is a clear difference between designs that they think consider as aesthetic and functional. Therefore, it is considered necessary for developing designs for jeans that can satisfy both aesthetic appreciation and functions for Korean consumer's body shape and each age group.

This study is to understand the problems of current police raincoats for professional policemen and conscripted policemen. Interviews and a survey were completed to investigate the wearing conditions of current police raincoats. The questionnaire was composed of questions on current wearing conditions of raincoat, motional adaptability, dimensional compatibility, design suitability and demographic information on the research target. The results indicated that the wearing frequency of raincoats had significant difference according to duty and age range. The main reason for the low wearing frequency was the uncomfortableness of working while wearing the raincoat, followed by the inconvenience of managing the raincoat after use and feeling hot while wearing the raincoat. The three most important factors when wearing a raincoat was pleasantness, activity capability and the functionality of the fabric. The satisfaction on body parts during motions tended to be evaluated lower as the raincoat size increased. The results of the dissatisfaction factors indicated that the raincoat hood had the most problems. There was inconvenience when using the equipment belt because officers have to wear their belts inside the raincoat. In regards to the fabric satisfaction level, respondents were less satisfied with ventilation, hygroscopicity, and drying time. Therefor it appeared that the current raincoat had problems due a lack of functionality in regards to ventilation, hygroscopicity, and quick drying; in addition, the satisfaction on motional adaptability had a significant difference according to raincoat size.

As children's apparel industry expands, there are many researches on purchasing and wearing children's clothing and optimal sizes, but researches on purchasing and wearing children's clothing and the appropriateness of sizes comparing average body shape and obese children are still inadequate. Therefore, in this research Late Elementary Schoolgirls ranging in age from 12 to 13 are categorized into the average or the obese body type, and by comparing and analyzing purchasing and wearing children's clothing and the appropriateness of its sizes between these groups, the problems in the size system of children's apparel are realized and the basic information about designing children's clothing for average body shape and non-average body shape(out-size)children are presented. The survey questions were composed of topics about general personal information, the purchasing practice and wearing practice, the appropriateness of its size when wearing children's clothing and the practice of mending apparel according to the satisfaction level of children's clothing sizes. Because subjects are often too big to wear children's clothing, and in the case of obese children the deviation of a body type is amplified, therefore in buying and wearing children's clothing, they demonstrate different forms of purchasing and wearing characteristics than adults. Considering the practice of increasing obesity in children due to westernized eating habits and decreased physical activities, along with developing programs for improving obesity, the development of an optimal size system in response to various body types will become an important challenge.

The purpose of this study was to investigate the changes in the flexicurve kyphosis index (KI), the flexicurve lordosis index (LI) and the distance from the inferior angle of the scapula to the nearest vertebral spinous process (DS), as a dependent variable of scapular protraction, after applying of adolescents with thoracic hyperkyphosis using three different garments. A repeated measures design was used. Ten adolescents ($15.8{\pm}1.0$ years) with thoracic hyperkyphosis ($40.1{\pm}3.7$ Cobb angle) were recruited from a university hospital. A flexicurve ruler was used to measure KI and LI and a scoliometer was used to measure DS under three different conditions: wearing-a hospital garment (HG), wearing-a sham garment (SG), and wearing-an experimental garment (EG). KI under EG condition was significantly decreased compared with that wearing the HG. However, there was no significant difference between wearing the SG and HG. LI when wearing the EG was significantly increased compared with that when wearing HG. However, there was no significant difference under SG and HG conditions. DS when wearing the EG was significantly decreased compared with wearing HG. However, there was no significant difference between the SG and HG. The results of this study show that the EG was effective in decreasing KI, but not effective in decreasing LI. Hence, the effect of the EG for correcting sagittal spine angle in adolescents with thoracic hyperkyphosis is still debatable. However, since we showed that DS decreases in the EG, this method could be applied in correcting the scapular protraction.

Purpose: This study was conducted to investigate changes in the cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort following the wearing of a trunk brace during smartphone watching. Methods: To calculate the number of subjects for this study, an analysis with G^*Power was performed at a statistical power of 0.8, an effect size of 0.5, and a significance level of 0.05, based on the results of a preliminary experiment on five subjects. In total, 27 adult men and women were recruited who had been informed of the study's purpose and process and had agreed to participate. All subjects watched content on a smartphone for 20 minutes in the same posture and conditions while wearing and not wearing a trunk brace, and then their cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort were measured. Results: Compared to the non-wearing of a trunk brace, the wearing of a trunk brace resulted in a statistically significant smaller decline in cervical extension and right-side cervical rotation (p<0.05). When the subjects wore a trunk brace, their right- and left-side cervical and right-side lumbar pressure pain statistically significantly improved when compared to not wearing a trunk brace (p<0.05). They also perceived a significantly lowered level of comfort 20 minutes after wearing a trunk brace compared to immediately after wearing it (p<0.05). Conclusion: The trunk brace was effective in reducing declines in right-side cervical rotation and the occurrence of left- and right-side cervical and right-side lumbar pressure pain. The findings indicate the need to improve the perceived comfort of trunk braces.
