  • This study is designed for improving wearing styles for middle-aged women who are in unsatisfactory body types and also providing the basic information about the suitable clothing designs for them. This study focuses on what kinds of body types they perceive, what the differences are between the perception of their body types and the real ones, and how the actual clothing styles can be affected by those perceived body types. This study is based on the survey of the perception of body types, the clothing styles, and the satisfaction level of body cathexis, while measuring body size of each person responded. The data were analyzed by Mean, ANOVA, Duncan-test of SPSS Win. (ver 10.1)program. The results are as follows: 1. The perception of their body types can be categorized into three clusters, the obesity, the arm & leg obesity, the slender. 2. By and large, Middle-aged women perceive their body types exactly what they we. However, they show a relatively subjective view on the upper arm girth, ankle girth, and arm length 3. The abdomen is at the lowest satisfactory part in body cathexis for the entire groups responded, and there are some differences among the perception of their body types in whole body silhouette and trunk. 4. Middle-aged women who perceive themselves as a bit slender show a tendency of having tight and revealing clothing styles, while the obese who perceived themselves wouldn't take them as appropriate dresses.

  • The precaution to spray with agricultural chemicals is very important, in particular personal protective equipment against pesticide in order to protect farmers# pesticide poisoning. The Ministry of Agriculture and Forestry has proclaimed the announcement of pesticide proof clothing(PPC) in 1983, and revised it in 1987. The announcement had many performance items to achieve the high-quality protective clothing for pesticide including weight, density, force strength, dimensional change(in washing and drying), fastness(dyeing, washing, sweating and rubbing) and water resistance of clothes. Announcement of the PPC has better durability and penetration resistance function than former days, but the plenty of farmers didn#t wear it because of the intolerable heat. To increase wearing rates, the pesticide proof clothing must be estimated the water-vapour resistance. From the results, the developed PPC with polyester treated water-repellent showed the more excellent comfort than an existing PPC with nylon coated polyurethane. But the developed PPC appeared to have the low water-vapour resistance. Therefore, it is suggested that the property of pesticide penetration must be evaluated through the field test in the future study.

  • The purpose of this study is to obtain science high school students' perceptions of scientists and their work before and after the Green Investigation program with scientists. This study also attempts to determine whether the program affected the participants' perceptions of scientists and their work. A modified DAST was carried out with 64 high school students. Findings revealed that Korean science high school students had normal perceptions of scientists, such as images of 20 to 30 year old males wearing laboratory coats and working alone in research labs with test tubes, flasks, and several machines in the background. After the intervention, students drew fewer typical items representing scientists and had significantly different perceptions of their work places between the pretest (M=1.69, SD=1.14) and posttest (M=1.96, SD=1.24, t=4.43, p<0.001) with the eta squared statistics (.24). These findings reflect the need for continued efforts of developing green investigation programs with scientists for students. Some future studies based on this study are also introduced.

  • A door checker holds a car door at several opening angles and limits the maximum door opening, so that the door does not bump against to passengers. Recently, the performance of door checker becomes more important as the feeling of door opening and closing effects on the quality of a car. However, some of door checkers make squealing noise when they are used for ages, which causes consumer's complaints as well as decreasing commercial value of the product. In this study, after various experiments for the noise, we concluded that the major reasons of the noise are acceleration of wearing and loss of lubricant due to impurities in working parts. Therefore, we developed a new mechanism of door checker which can resolve the major reasons of the noise. The developed mechanism is effective to prevent inflow of impurities and loss of lubricant by locating working parts in the case. We also proved that the developed mechanism does not make any noise after the test of 50,000 times of operations.

  • Online shoppers are not able to try clothing on. Therefore, the pictures of clothing on the website play a significant role when shoppers make decision on their purchase. There are generally three different ways to show clothing at online shops. The first one is showing only clothing images, and the second one is showing the pictures that have actual fitting models wearing clothing on (In this case, Model's face is mostly not shown in the picture.), and the third is showing the pictures of professional fitting models who wear goods. The shopping malls adopt each of the different ways but little is known about affect on purchasing from these three ways. The aim of this study is to figure out how the online shopper's emotional status is affected by these three ways of presenting pictures of clothing. At first, we developed a set of adjective words of human emotion to set up the evaluation criteria for user's emotional status. Those adjectives are originally from the precedent research on human emotion. To cut 99 adjectives down to a proper number for the criteria, we conducted a preliminary survey, and finally, 5 adjectives are selected as appropriate criteria for evaluating users' emotional status while they are shopping. Those five adjectives are 'possess','sensual', 'unique', 'tasteful', and 'stylish'. Then, we conducted the main survey showing 10 kinds of cloth (each cloth was consist of 3 ways). And in the page of model images, we measured the model's preference for understanding the relation with customer's emotion criteria of the product. As a result of the test there was statistically significant difference between product only images and anonymous images, but there was no significant difference between anonymous images and model images. And the preference of the model and value of the emotion criteria have large correlation except 'unique' criteria. It is expected that the result in this study will help to build new marketing strategy which satisfy customers' emotion.

  • The research thesis has been intended to make a comparative analysis on the basic bodice pattern and basic skirt pattern changing on the basis of setting waist line of dress form in an effort to set reasonable standards in selecting the standard lines of drees form. The thesis has made the wearing evaluation by producing the sample of upper and lower dress based on A pattern and B pattern. In details, A pattern functions to keep waist line flatly down from lateral waist-right to posterior waist in a little curved state, paralleling bust line and hipline with waistline. And, B pattern functions to keep waistline, bust line and hipline horizontal paralleling with ground surface. SPSS win 10.1 program was used for the analysis of evaluation and t-test. The result is as follows: For basic bodice-front of upper dress, A and B patterns have made little significant difference. With regard to basic bodice-back, B pattern has got the higher evaluation than A pattern, in the pattern stability and appearance. For basic skirt pattern, A pattern has got the lower evaluation in the aspect of total back appearance, back dart, hip line, and waist line, and front drape. Basic bodice pattern of A pattern, which takes on the different horizontal standard lines of dress form depending on the selection of waistline, and basic skirt pattern has scored less in terms of pattern stability and appearance.
