This study identifies the antecedents of trust in the examination of the effects of the antecedents of trust on trust in apparel manufacturer-contractor relationships. A total of 92 apparel manufactures participated in this study. A factor analysis, Cronbach's alpha coefficient, and multiple regression analysis were conducted for the statistical analysis. Five antecedents of trust were classified: flexibility, opportunistic behavior, communication, specific investment, reputation. Two factors of trust were identified: credibility and benevolence. Flexibility, communication, and reputation of a contractor positively influenced the credibility of an apparel manufacture in a contractor. Flexibility, communication, and specific investment of a contractor positively relate to the benevolence of an apparel manufacture in a contractor. However, the opportunistic behavior of a contractor did not relate to either the credibility of an apparel manufacture or the benevolence in a contractor. The results of this study provide empirical evidence of the impact of flexibility, communication, specific investment, reputation on trust in apparel manufacturer-contractor relationships, and additional insight for selecting contractors that seek to improve trust in apparel manufacturer-contractor relationships.

The purpose of this study was to examine the outdoor sportswear purchase behavior, outdoorwear sportswear brand preference, functional fabric awareness, and benefits sought. The research was performed through in-depth interview during February to March 2011. Data were collected from 10 consumers who had purchased outdoor sportswear and experienced camping in 6 months. First, the results from study showed that functionality/comfortability, design, color, and brand name were important factors in selecting outdoor sportswear. Offline stores were the main place to purchase, however, internet shopping mall and portal online community were another shopping channel as well. Second, respondents preferred imported outdoor sportswear brand to national brand. According to the study, the respondents trusted the imported outdoor sportswear quality based on the brand name, value, and brand history more than national brand. Third, consumers who had low functional fabric awareness were more likely to evaluate apparel products based on the brand name. Knowledge levels for textile functions were high in elastic, UV protection, air permeable, and antibacterial properties. The essential features for camping were water absorbing and quick dry, water resistance, wind proof, UV protection, and fire retardant properties. Finally the results showed that there were two sportswear benefit soughts: functionality and status ostentation.

The purpose of the present study was to test the behavior of dietary life, the preception of body image and the attitude of body weight control of the subjects, and to imagine difference of value evaluation about thirteen foods. the subjects were 570 high school students who were living in Seoul. The results can be summarized as follows: 1. In selecting actual and ideal body sizes from a series of five outline drawings of female figures that ranged form 20% underweight to 20% overweight, 64% of the subjects selected overweight drawing s as their actual sizes, and 85.1% of the subjects selected underweight ones as the ideal sizes. 59.3% of the subjects had a desire to lose weight, 20.8% to gain weight. Those who think they are thinner than standard body weight were more satisfied with their body sizes than those who think they are fatter than that. Most subjects (79.8%) were concerned about their weight control, and the majority of them (36.1%) began to take concerns about it in their high school days, through the conversation with their friends about their body sizes. 2. In this study, thirteen foods were chosen as samples; rice, bread, salad, milk, cola, cider, juice, duck-bok-ki, chocolate, batterfriend foods, chinese noodles, cookies, fruits. Most of them evaluated foods on the basis of the taste. They valued fruits over any other foods as least fattened food, while they thought of such foods as rice, cola, cider, ice-cream, chocolate, batter-fried food, chinese noodles as fattened foods.

Though the history of finite element analysis in field of powder metallurgy is not short, industrial engineer is still being dependent on the trial and error approach based on engineer's experience in selecting process conditions. This problem is mainly due to the difficulty in establishing models for the behavior of a powder compact during compaction and sintering as well as finding material parameters for the models and the absence of CAE software with which industrial engineer can easily investigate the effect of process conditions on the quality of product. Therefore, we established very simple and cheap procedure to find material parameters for powder compaction behavior and implemented it in self-developed commercial CAE software for powder metallurgy, PMsolver. Basically, the development strategy of PMsolver lies on simplification and convenience so as for industrial engineers to use it with least training. Using PMsolver, optimal process conditions were found for some geometry and powders. Prior to process condition design, the accuracy of finite element analysis was verified.

Squeeze film dampers (SFDs) have been commonly used to effectively enhance the dynamic behavior of the rotating shaft supported by rolling element bearings. However, due to the recent trends of high operating speed, high load capacity and light weight in rotating machinery, it is becoming increasingly important to change the dynamic characteristics of rotating machines in operation so that the excessive vibrations, which may occur particularly when passing through critical speeds or unstable regions, can be avoided. Semi-active type SFDs using magneto-rheological fluid (MR fluid), which responds to an applied magnetic field with a change in rheoloaical behavior, are introduced in order to find its applications to rotating machinery as an effective device attenuating unbalance responses. In this paper, a semi-active SFD using MR fluid is designed, tested and identified by means of linear analysis to investigate the capability of changing its dynamic properties such as damping and stiffness. Furthermore, the proposed device is applied to a rotor system to investigate its potential capability for vibration attenuation: an efficient method for selecting the optimal location of the proposed damper is introduced and control algorithm that could improve the unbalance response properties of a flexible rotor is also proposed.

The term "social marketing" was first introduced in 1971 to describe the use of marketing principles and techniques to advance a social cause, idea, or behavior. Social Marketing is a strategy for changing behavior. It utilizes concepts of market segmentation, consumer research, product concept development and testing, directed communication, facilitation, incentives, and exchange theory to maximize the target adopters' response. Social marketing requires knowledge of each target-adopter group, including its 1. social demographic characteristics, 2. psychological profile and 3. behavioral characteristics. To know the target adopters in these three related ways enables social marketer to make more accurate predictions. In addition to differentiating among and selecting target adopter groups, the social marketer will identify influence-holding groups, or influentials, who can affect a program's success. Great changes and opportunities exist to produce changes in the ways that individuals and groups think and behave and in meeting human needs. The balance of the scales of social change, we hope, will shift away from the use of force and violence to the use of persuasion and voluntary action. I trust that this dissertation will be useful highlighting the strategies and means of peaceful, planned social change designed to elevate the quality of life.

본 연구는 대구지역에 거주하는 중ㆍ고등학생 639명을 대상으로 청소년의 소비자의식이 의복구매행동에 미치는 영향을 분석하였다. 연구의 결과를 요약해 보면 다음과 같다. (1) 소비자의식 유형은 권리의식, 소비자정보의식 브랜드지향의식, 책임의식의 4개 요인에 따라 실리지향, 상표지향, 소비자의식지향의 3가지 집단으로 분류되었다. 실리지향 집단은 소비자의 권리의식, 소비자정보, 책임의식은 보통 정도이나 브랜드지향의식은 다른 집단에 비하여 낮게 나타났으며 상표지향 집단은 권리, 소비자정보, 책임의식은 낮으나, 가격과 상표에 대해서는 관심이 높게 나타났고, 소비자의식지향 집단은 소비자의 권리의식이 강하고, 소비자정보를 많이 탐색하며, 가격과 상표를 중요시하지 않고, 책임의식도 높게 나타났다. (2) 남학생에 비하여 여학생들이 소비자정보의식과 브랜드지향의식, 책임의식이 높으며, 한달 용돈이 7만원 이상인 집단은 7만원 미만인 집단보다 권리의식은 낮고, 브랜드지향의식은 높게 나타났다. 아버지가 농림ㆍ 생산직에 종사하는 청소년들이 권리의식은 높게, 소비자정보의식은 낮게 나타났으며, 어머니가 전문ㆍ 행정ㆍ사무직에 종사하는 청소년들은 소비자정보의식이 조금 높게 나타났다. 월평균 가구 소득이 500만원 이상인 가정의 자녀는 다른 집단에 비해 브랜드지향의식이 조금 높게 나타났다. (3) 의복을 구입하는 주된 동기는 필요에 의해 구매하는 것으로 나타났으며, 과반수 정도가 계획구매를 하고 있으며, 주로 의류전문쇼핑몰을 이용하고, 의복에 대한 정보는 ´제품´, ´가족 친구의 조언´에서 주로 얻고 있었다. 의복 선택 시 중요한 요인은 디자인 가격, 어울림 순으로 나타났으며, 구매 후 불만으로 가격, 서비스, 바느질상태를 표시하였고, 실제로 불평행동을 하는 청소년은 42%로 친지나 친구에게 불만스러웠던 점에 대해 불평한 경우가 가장 많았다. (4) 의복구매행동현인의 요인분석에서 구매정보원은 ´중립적 정보원´, ´개인적 정보원´, ´상업적 정보원´, 구매선택은 ´조화´, ´유행´, ´관리성´, 불만원인은 ´외관´, ´품질´, ´서비스´의 3개 요인으로 나타났다. (5) 소비자의식형 집단은 개인적, 상업적 정보를 많이 활용하였으나 상표지향형 집단은 정보원을 중요시하지 않았다. 의복 선택요인으로는 소비자의식 집단은 조화와 관리성을 중시하나 상표지향집단과 실리지향집단을 관리성에 관심이 낮았다. 의복구매장소로 실리지향집단은 양품ㆍ보세점과 의류도매상가를, 상표지향 집단은 의류전문쇼핑몰이나 유명상표 대리점을, 소비자의식지향 집단은 의류전문쇼핑몰이나 상설할인매장을 주로 이용하였으며 소비자의식 집단은 사적, 또는 직접 구매 후 불평행동을 많이 취하고 실리지향 집단은 거의 불평행동을 취하지 않는 것으로 나타났다.
