As the fashion phenomenon changes in the direction of respecting individual tastes it needs to make and effort to search individual clothing-wearing motives. In this study the face to face interviews were carried out to 42 people for 4 months from October 1996 to January 1997. By means of the qualitative data analysis their statements were analyzed. 6 groups were classified on the basis of clothing-wearing motives. Generally consumers began to cognize the necessity of clothing and develops it to situational appropriateness psychological comfort impression management distinction desire and finally attention -receiving desire. The levels of clothing-wearing motives were also interpreted as introversion-extroversion theory. These 6 groups were named in consideration of the highest level of their clothing -searing motives They were respectively the least clothing-cognizing group situation-appropriateness cognizing group psychological comfort cognizing group impression management group distinction desire group attention-receiving desire group. The characteristics of each group were represented based on the interview results and the consuming-behavior of each group was compared. finally the interaction of the clothing-wearing motives and the fashion phenomenon was discussed.

The purpose of this study is to develop functional and sensible brassiere for middle-aged women. As a methodology, engineering design process, especially, QFD(Quality Function Deployment) was adopted to translate consumer's needs into product design parameters. Wearing tests of commercial brassiere were performed for the development o subjective measurement scale. The environmental condition was controlled at 28$\pm$1$^{\circ}C$, 65$\pm$3%RH. As results, 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. Regression equations with the subjective evaluation descriptors were developed for the prediction of wearing comfort of brassiere. (R2=.82) 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.

The purpose of this study are to analyze the images of‘home life’through the goals of 1st-6th secondary Home Economics education curriculums and to identify the images of ‘home life’held by undergraduate students(83). As results, in the goals of 1st-6th secondary Home Economics education curriculums, 1) the term of ‘home life’is used most frequently, and ‘home life’is confused with ‘daily life’. 2) ‘Home life’is used directly or expressed with clothing life, food life, shelter life, consumer life, etc. in the curriculum goals. 3) ‘Home life’is dealt differently with ‘family life’. 4) The image of “home life”has showed traditional sex role identification. In the replies of undergraduate students, the images are classified with following：1) the images of ‘home’were expressed warmth(hearth), relexation(ease or comfort), sharing, basic unit of society, and conflict and oppression. 2) The images of ‘home life’were expressed hearth, sharing, conflict(interaction), relexation(ease or comfort or sability), routine(act or household art), basic unit(shelter), responsibility and obligation, and reproduction(biological meaning). 3) The images of ‘daily life’were expressed routine(simplicity of boring or routine acts), comfort(stability), oppression, diverse activities in everyday, human relationship, and social life.

Most of design parameters of Railway Structures are determined by the serviceability requirements, rather than the structural safety requirements. The serviceability requirements come from Ensuring of running safety and ride comfort of train, reduction of track maintenance working Track-Bridge interaction should be considered in the design of railway structures. In this study, a numerical method which precisely evaluate an axial force of rail and a rail expansion and contraction when turnout exist in succession on a CWR of bridge is developed.

교량을 주행하는 열차의 주행안전성과 승차감의 확보를 위해 Eurocode, 신간선 기준, 호남고속철도 설계지침 등에서는 교량의 연직변위, 연직가속도, 면틀림 등의 항목으로 제한하고 있다. 그러나 이와 같은 제한 기준은 교량 설계자의 편의를 위한 간접적인 방법이다. 또한 이와 같은 기준은 일반적인 경간(Eurocode의 경우 120m 이하)에 대한 제한 기준으로서, 이 이상의 장경간 교량의 경우에는 교량/열차 상호작용 해석 등에 의한 면밀한 검토를 제안하고 있다. 본 연구에서는 교량/열차 상호작용 해석을 수행하여 열차에서의 응답을 통해 교량 상을 주행하는 열차의 주행안전성 및 승차감을 직접적으로 평가하고자 하였다. 즉, 중앙경간 300m의 현수교를 주행하는 KTX 열차에 대하여 열차 내부의 가속도와 윤중감소율을 구해 평가하는 방법을 취하였다. 또한, 이동 열차하중과 지진하중이 동시에 작용할 경우를 고려한 교량/열차/지진 상호작용해석을 수행하여 지진 시의 응답을 평가하였다.

Physical variables related to the subjective evaluation of wear comfort were explored. Experimental fabrics was those used in the previous paper where subjective sensations of women's thin shirts were reported. Fabrics include 100% cotton (unfinished), 100% cotton (water repellent finished), cotton/polyester 35/65 (unfinished), cotton/polyester 35/65 (peach skin finished), 100% polyester fabric(plain), 100% polyester crepe. Among various physical properties of the experimental fabrics, heat 8E moisture transport properties and surface properties were chosen as important variables based on the regression coefficient. Especially, humidity at the microclimate in dynamic mode was highly correlated to the subjective evaluation and appeared to be a sensitive physical predictor, compared to dry thermal transmission rate or water vapor transmission rate. Surface characteristic parameters, however, did not show consistant trend in the prediction of the human's subjective sensation. Interaction between surface properties and humidity measurement was also observed.

This paper addresses vibration comfort evaluation on suspension bridge subjected to moving vehicles. The moving load method is commonly employed for the analysis, even though it is less accurate than the moving mass approach which considers vehicle-bridge interaction effects and roughness of the pavement. In this study, a parametric study on modeling method by means of the moving load technique, such as the number of modes included in the analysis, types of moving loads, and length of the stiffening girder, is carried out. The numerical result indicated that use of the triangular pulse load may result in significant overestimation on vibration discomfortness.

The purpose of this study was to develop the better fitting and more comfortable sleeve pattern for women's jacket, as the first step. Five types of existent sleeve pattern were collected, made and worn compared with the sensory evaluations method. The main results of this study were as follows 1. Sensory evaluation for appearance; According to the result of Duncan's multiple range test among the five sleeve patterns, TOJAIUN method sleeve was most satisfactory, and the next was the JUNGMYUNGJA method sleeve followed by NASAN, MOONWHA, ESMOD method sleeve. 2. Sensory evaluation for comfort; The result of Duncan's multiple range test showed that the ESMOD method sleeve was comfortable, and the next was the Japanese MOONWHA method sleeve followd by JUNGMYUNGJA, TOJAIVN, NASAN method sleeve. The result of 3-way ANOVA, main effect for 3 independent variables and interaction for pattern x part, posturers part showed significant difference.

This study deals with the performance evaluation of writing for designing handwriting instruments ergonomically. Experimental tests were executed on ballpoint pen., felt-tip pen, pencil, sharp-pencil, and fountain pen for ease of use and reduction of the muscles fatigue. The writing time and the degree of comfort of writing by subjects were measured on the diameters of five writing instruments. The results indicated that the ballpoint pen was rated significantly superior to the others in writing speed attribute and the instrument with the least fatigue was the fountain pen. There was a significant interaction effect between the types of instruments and their size in diameters. The diameter of instruments for considering time and comfort together was verified that the size of 9.5mm was efficient for ballpoint pen, the size of 8.1mm for felt-tip pen, the size of 7.5mm for pencil, the size of 8.2mm for sharp-pencil, and the size of 9.1mm for fountain pen.
