This study explored the determinants that influence purchase intention in online shopping based on augmented reality applications. The main results are discussed focusing on hypotheses as follows. First, interactivity had a positive effect on psychological ownership. Second, interactivity had a positive effect on decision comfort. Third, psychological ownership had a positive effect on decision comfort. Fourth, psychological ownership had a positive effect on purchase intention. Fifth, decision comfort had a positive effect on purchase intention. Therefore, in online shopping based on augmented reality applications, interaction determines psychological ownership and decision comfort, and psychological ownership and decision comfort can be evaluated as key factors that promote product purchase intention in online shopping. In order to increase purchase intention in online shopping, a marketing strategy is required to increase interactivity, psychological ownership, and decision comfort through augmented reality applications.

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.

A standard for the vibration magnitude of a maglev train is presented herein to ensure a comfortable ride for the passengers. The vibration magnitude is determined from the vertical acceleration of the car body. A parameter analysis of the maglev train system is then performed considering the vehicle-structure interaction, and a deflection limit of L/1300 is proposed to satisfy the standard for the vertical acceleration. The proposed deflection limit is applied to the dynamic analysis of the actual maglev train system to assess applicability. Compared with the existing standard for the guideway structure, the proposed deflection limit is expected to enable economical design and construction.

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.

The estimation of traffic safety and passenger comfort when the train is running on the bridge is a estimation unique to the railway bridge. The standards for such estimation are included in the Eurocode, the Shinkansen design criteria, and the design guideline of the Honam High-speed railway. The items are bridge responses including vertical displacement of bridge, vertical acceleration, and slab twist. In principle, a direct estimation based on the train responses has to take place. However, the estimation based on the bridge responses can be seen as an indirect estimation procedure for the convenience of the bridge designer. First, it is general practice that traffic safety can be verified as a derailment coefficient or wheel load decrement The general method of estimating passenger comfort is to calculate the acceleration within the train car-body. Various international indexes have been presented for this method. In the present study, traffic safety and passenger comforts are estimated directly by bridge/train interaction analysis. The acceleration and wheel load decrement are obtained for the estimation of traffic safety and passenger comforts of a suspension bridge which has main span length of 300m. Also, the consideration of seismic load with simultaneous action of moving train is done for bridge/train/earthquake interaction analysis.

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.
