A research to maximize the force transmitted from a vibration motor at the vibration mode, installed in the cellular phone jig, is presented in this study. When the natural frequencies corresponding to the structural vibration modes of the set exist within the range of the driving frequencies acquired by changing the RPM of the vibration motor, the structural vibration resonance is applicable to maximization of the vibration force sensible to the human body such as hands, arms, and hips. The analytical modal analysis using the Finite Elements and the experimental modal testing for the set jig were performed in order to understand the structural modes and the corresponding frequencies. Then the dynamic responses of the set jig to the given driving frequency were measured and the results on maximizing the vibration were confirmed by the FEM dynamic simulation.

The purpose of this study is to express the sexuality of feminism in the modern fashion. As for the methods of research, literary research was carried out using reference based on feminism history and sexuality concept and demonstrative analysis was undertaken using 2000's collections photographs. In the results of that, the sexuality of gender resistance feminism is featured by three key words: sado-masochism sexuality, bi sexuality and hetero sexuality. First, sado-masochism sexuality shows fetish look and dominatrix look shown in the strong attitudes. Sado-masochism sexuality is setting fetishes such as mask, whip, chain, metallic materials and tight leather boots. Second, bi sexuality presents mannish look of soft and feminie style's slim pants suit with ruffle, flounce and decorated detail blouse. and fetish look wearing of sexual symbol clothes such as corset and bustier. Third, hetero sexuality represent glamour look which exposure and emphasis of breasts, hips and other sexual symbols.

The purpose of the present research is to determine, for a sample of female college students, the effects of body-cathexis and importance of ideal body image on satisfaction with ready-to-wear. The sample included 177 female college students aged from 18 to 25. To measure the variables, an instrument was developed based on previous studies. Body-cathexis and importance of meeting the ideal body image were measured for five areas of body parts; head/upper body, lower body, height, weight, and torso. Satisfaction with ready-to-wear includes satisfaction with the fit at pant length, thighs, hips, waist, bust, and neckline, and with the variety in ready-to-wear. Research hypotheses were tested using multiple regression. The results showed that there was a positive impact of body-cathexis for a specific body area on ready-to-wear satisfaction which is related to the body area. The effect of importance of meeting the ideal body image on ready-to-wear clothing was different in regard to different areas of body parts.

Injection molded plastic parts have many surface detects: weld line, sink mark, flow mark, gloss, shading, scratching, and so on. Because these surface faults have not been accepted esthetically, plastic parts are Produced through painting or texturing. The purpose of this paper is to develop a paintless molded part of TV Mask Front by flow control method and gas-assisted injection molding. In order to minimize defects from injection molding, this study was carried out using computer aided injection mold filling simulations using MF/FLOW and MF/GAS. Based on these numerical results, we developed FR(Flame Retardant) HIPS and established guidelines of part design, mold design, and Processing conditions. We have achieved of cost sayings, improvement of productivity, and utilization of recycling by eliminating surface defects and painting process.

The purpose of this study was to investigate the Effective X-Factor in golf swing. The term X-Factor means the relative rotation of shoulders with respect to hips during the golf swing. To ascertain the Effective X-Factor that resulted in a high club head speed at impact six golfers' swing motions were videotaped and analyzed using three-dimensional techniques. The results can be summarized as follows. The standard deviations of the professionals' average club head speeds were higher than the amateurs'. This means that the professionals' swing skills were better than amateurs' in driving accuracy and consistency. As the club head speeds were increased gradually the X-Factors and the club head speeds had reached to the subjects' average club head speeds, but the X-Factors and the club head speeds were not increased above the subjects' average club head speeds. The X-Factor Stretch early in the down swing was existed and Professional stretched values were higher than the amateurs. In conclusion my research results suggested that the increase in Effective X-Factors had no relationship to the increase in club head speeds.

The purpose of this study is to analyze the perceptions of obesity among appearance-conscious women in their 20s. It is intended to provide data necessary to produce garments for obese body types by identifying adult women's subjective assessments of obese body types and characteristics. The data were analyzed using Q Methodology in the QUANL program for PC. Type 1 was recognized as uniformly fat in the abdomen, with almost the same width and thickness. Type 2 was perceived to have more fat in the upper body and back, broad shoulders, and an inverted body type. Type 3 was perceived as having a fat lower half of the body, hips wider than the chest, and large thighs. Type 4 was identified as having few curves and fat concentrated in the abdomen. Further research of other age groups and regions is needed to ascertain the difference between perceived and actual body types.

본 연구는 딥티슈마사지와 일라이트병행 딥티슈마사지가 체형변화에 미치는 영향을 검증하고, 각각의 적용 방법에 따른 체형변화 효과를 확인하여 체형개선에 효율적인 방법을 제안하고자 하였다. 연구의 대상은 30대 여성 20명을 난수표방식에 따라 각각 10명으로 나누어 딥티슈마사지, 일라이트병행 딥티슈마사지를 1회/주 8주 동안 진행하였다. 시점별로 실험전, 4주 경과, 8주 경과에 따라 모아레토포그래피를 사용하여 극돌기 기울기, 견갑부, 둔부의 변화 값을 측정하였다. 수집된 자료는 SPSS v. 21.0 통계 패키지 프로그램을 활용하여 최종 분석하였으며, 그 결과는 다음과 같다. 연구대상자의 일반적 특성은 전문직이 가장 높게 나타났고, 기혼자가 90%로 이 중 77.8%가 출산 경험자로 78.6%가 자연분만 하였으며, 자녀수는 두 명이 57.1%로 가장 높게 조사되었다. 실험 전 일라이트병행 딥티슈마사지 적용군과 딥티슈마사지 적용군의 극돌기 기울기, 견갑부, 둔부를 측정한 결과 일라이트병행 딥티슈마사지 적용군이 딥티슈마사지적용군에 비해 모든 항목에서 다소 높게 나타났으나 통계적으로 유의미한 차이는 보이지 않아 동질성을 확보할 수 있었다. 마사지 적용방법에 따른 체형변화 비교는 일라이트병행 딥티슈마사지 적용군이 딥티슈마사지 적용군보다 시점에 따라 극돌기 기울기, 견갑부, 둔부의 감소율이 크게 나타나 유의한 차이를 보였으며(p<.05, p<.01), 일라이트병행 딥티슈마시가 딥티슈마사지보다 체형변화에 더 효과적 방법으로 확인되었다. 이에 일라이트병행 딥티슈마사지는 체형변화 개선에 활용 가능한 유용한 요법으로 제안하며, 피부미용 산업현장 및 관련 분야에서 활용하기를 기대해 본다.

Objective: The objective of the study is to develop a portable assistance device to help elderly users reduce strain on the knee and leg muscle while the elderly are standing up. Background: The pose of standing up from a chair is a basic movement, but the elderly often have difficulty standing up due to their weak muscles. We focus on designing a solution that helps the elderly reduce physical problems and support them standing up. Method: This study consists of three parts. Part I explores the way to reduce the refrain of leg muscle while standing up from a chair. In the process of structural development, we found that the moment is minimized when user pushes down the armrests due to a decrease in the force acting on the center of mass. In part II, a user test of 20 participants was carried out to rank the order of comfort of two stimuli: the chair with fixed armrests and the chair with the four-link mechanism that we created-in three different ways; (1) to stand up without touching armrests, (2) to stand up by pushing down on fixed armrests, and (3) to stand up by pushing down on armrests and being supported by the mechanism. To examine the statistically significant differences among the rank means, a Friedman test was conducted. In part III, we analyze the results of the user test and interview feedbacks, focusing on establishing a design strategy from UPO and visualizing it in 1:1 scale. Results: In part I, we decided to develop the four-link mechanism. The bottom is lifted up as the link rises. In part II, based on the rank data, we empirically found that UPO was assessed as the most comfortable during the stimuli. The thigh angle is smaller and the bottom of UPO is separated from a seat. In part III, after assessing the results and feedbacks, we created a visualization strategy for UPO: light, friendly, and novel. Conclusion: The portable and non-mechanical UPO comprises a four-link system that lifts the user's hips while standing. It can help users avoid knee and leg muscle strain. Its universal design considers the elderly's difficulties. Application: In a future study, combining light and durable material in UPO is expected to increase its usability. And this study is an opportunity to design various types of standing assistance devices.
