The purpose of this paper is to investigate the adequate clothing pressure of upper and lower body foundation garment and subjective assessment of those compressive foundation depending on various wearing conditions. Eighteen women in their 30s and 40s participated in the experiments for this study to evaluate the level of clothing pressure of girdle and waist nipper. Subjects were divided into two groups by the wearing habits of foundation, one is the group of wearing foundation garment 'tightly' and the other is 'loosely', It was found that the group wearing foundation garment 'loosely' was much more sensitive than the group of 'tightly' in everyday life. The adequate pressure of upper foundation, waist nipper was about $1.5{\pm}0.8$ kPa which is lower than that of the lower body foundation, girdle. And at the same time, the sensitivity of the pressure level was higher when subjects are wearing waist nipper compared with wearing girdle. Therefore, precise pattern making process is necessary to meet the adequate level of pressure of the upper body foundation such as waist nipper, specially for those who used to wear clothing loosely.

The purpose of this study was to investigate the relationship of time pressure, discretionary time, and subjective well-being(SWB) of university students. In order to achieve it, 493 university students(220 male, 232 female) completed a set of questionnaires about time pressure, discretionary time, subjective well-being. The t-test, multiple regression analysis were performed to analyze the data. The results are as follows. First, There were significant differences among the positive emotion, the negative emotion and time pressure. However, there was no statistically significant difference between the satisfaction of life and discretionary time according to gender. Second, time pressure was negatively correlated with the satisfaction of life of university students but positively correlated with the negative emotion. The discretionary time was positively correlated with the satisfaction of life of university students but negatively correlated with the negative emotion. Time pressure and discretionary time were not correlated with the positive emotion. Finally time pressure significantly correlated with the satisfaction of life, the negative emotion. And It seems that time pressure had an especially strong effect on the negative emotion. Such results imply that time pressure is important for reducing university students's the negative emotion, a subfactor of subjective wellbeing.

30-40대 중년 여성 100명을 대상으로 Brassiere착용 상황, 요구사항을 조사, 분석하고 시판 Brassiere의 착용실험을 통해 착용감을 평가함으로써 Brassiere에 대한 소비자 요구와 착용감 평가차원을 추출하였다. 주관적 착용감 평가실험은 25명이 참여 하였으며, 실험은 온도 28$^{\circ}C$, 습도 65%RH의 인공기후실에서 실시하였다. Brassiere 착용감의 구성차원을 추출하기 위해 평가용어를 이용하여 평정한 값들을 요인분석한 결과, fit성 및 체형보정성, 심미성, 압박감, 동작에 의한 브라의 착용위치 변화의 4가지 요인으로 이루어졌음을 확인하였다. Brassiere 착용감을 예측하기 위해 평가용어를 회귀변수로 하여 회귀분석한 결과, Y=3.262+0.723X$_1$-0.646X$_2$ (Y: 착용감, X$_1$: 가슴과 컵모양이 잘 맞는다, X$_2$: 와이어 부분이 불편하다)로 나타났다. Brassiere 착용감에 대한 소비자의 정성적인 요구사항을 정량적으로 측정하기 위한 제품 디자인 요소중, 와이어와 주소재의 신축성이 착용감에 중요하게 작용하는 것으로 나타났다.

The purpose of this study was to analyze and determine the relationship between physiological responses including blood flow rate and garment pressure, and the feeling of restrictive tightness associated with the wearing skinny pants as a popular clothing style. Evaluation was based on material type, posture and activity type, and body part location. Five female college students took part in this research. Five kinds of experimental clothes with waist measurements of 66cm were chosen. An analysis of the selected skinny pants demonstrated the degree of the whole looseness was higher in this order: clothing type A>B>D>C, and E with E being knitted cloth. Garment pressure was the highest in the front knee portions and was lowest in the outside thigh region. Garment pressure was highest in this sequence : clothing type C>=D>A>=B>E. In terms of posture and activity types, garment pressure was the highest when research participants were crouching, and was the lowest when standing. The blood flow rate was highest in this order: clothing type E>D>B>A>C. Type C skinny pants impeded blood flow and demonstrated the tightest and most restrictive relationship. Blood flow rate varied depending on the type of movement and was highest in this order: getting up, rowing, kicking, jumping and O-shaped leg posture. The results of subjective pressure evaluation demonstrated that pressure was highest in this order: E>=C>B>A>D. These results suggests the need to improve on the patterns and the material design in the area of the front knees. The degree of the looseness when wearing skinny pants did not always correspond to garment pressure or subjective sensation.

This study analyzed the effects of skinny jean on women's health by questionnaire survey and measuring the pressure experienced under the clothing and participants' subjective view of the pressure level. The average size women in their 20s' waists is 26 inches and so three pairs of jeans were prepared and worn by 4 female participants. A survey was conducted to investigate how often participants wear skinny jeans and whether they had had any feelings of discomfort as a result of this. Participants responded that they hadexperienced middle to high levels of discomfort due to the high pressure inside skinny jeans. For the maximum value of clothing pressures, jean f2 at the part of buttocks showed $48.7gf/cm^2$. The pressure inside the clothing was found to be highest around the buttocks followed by the knees and finally the belly. The mean values of 7 measuring parts are different according to the jean type; f3 $20.8gf/cm^2$ > f2 $16.4gf/cm^2$ > f1 $15.5gf/cm^2$, which is corresponding to the order of pressure sensation, but not corresponding to the order of ease amount of clothing pattern: f2 > f3 > f1. Mean pressure values were also measured according to the body posture: they were found to by highest when sitting on a chair (21.3gf/$cm^2$), second highest when sitting on the floor ($19.2gf/cm^2$) and lowest when standing ($15.0gf/cm^2$). This is not always same to the order of participants subjective perceptions of the pressure, which is, they estimated pressure to be highest when sitting on the floor followed by sitting on a chair and lowest in a standing position.

Purpose: We present a case of anterior glenoid rim comminuted fracture that was treated with arthroscopic reduction and an AO headless compression screw (HCS) fixation. Materials and Methods: A 31-year old man complained of left shoulder pain after falling down on stairs. The anterior glenoid comminuted fragments were arthroscopically reduced. Fixation with an AO HCS was done after placement of 1.1 mm Kirschner wire as a guide pin through a standard cannulated anterosuperior portal. Results: Twelve months after the operation, union of the fracture was achieved and the range of motion was fully recovered. He did not complain of any discomfort during his activities of daily living. Conclusion: An AO HCS had various screw sizes and this was good for fixation of a small glenoid fracture and a long drill bit and screw driver were useful for fixation of deep seated glenoid fracture. A short guide wire could be replaced by a 1.1 mm K-wire. An AO HCS was useful for fixation of an anterior glenoid rim comminuted fracture.

Quality Function Deployment(QFD) is a product development tool which ensures that the voice of the customer needs is heard and translated into products. To develop a sensible brassiere for middle-aged women QFD was adopted. In this study the applicability and usefulness of QFD was examined through the engineering design process for a sensible brassiere for middle-aged women. The customer needs for the wear comfort of brassiere was made by one-on-one survey of 100 women who aged 30-40. The customer competitive assessment was generated by wearing tests of 10 commercial brassieres. The subjective assessment was conducted in the enviornmental chamber that was controlled at $28{\pm}1^{\circ}C,\;65{\pm}3\%RH.$ As a results, we developed twenty-one customer needs and corresponding HOWs for the wear comfort of brassiere. The Customer Competitive Assessment was generated by wearing tests of commercial brassiere. The subjective measurement scale and dimension for the evaluation of sensible brassiere were extracted from factor analysis. Four factors were fitting, aesthetic property, pressure sensation, displacement of brassiere due to movement. The most critical design parameter was wire-related property and second one was stretchability of main material of brassiere. Also, wearing comfort of brassiere was affected by the interaction of initial stretchability of wing and support of strap. Engineering design process, QFD was applicable to the development of technical and aesthetic brassieres.
