The purpose of this study was to investigate lifestyle of male college students and their preference of casual wear style. A questionnaire consisted of 60 lifestyle items, 1 casual wear style-preference question and demographic variables was developed. Data were collected from questionnaires distributed to male college students of 7 universities located in the Daegu${\cdot}$Gyeongbuk area during August 2003. After eliminating incomplete questionnaires, 303 were analyzed by descriptive statistics, factor analysis, cluster analysis, one-way ANOVA, and $x^2-test$. As a result of factor analysis on lifestyle items, 8 factors were determined: consumption and fashion orientation, future preparation, social concern, a wide range of thought and experience, health orientation, independent spirit, masculinity, and family orientation. 4 groups were identified on the basis of these 8 factors and named as active pragmatic group, liberal empirical group, prospective self-supporting group, and social accommodative group. Their component ratio were $30.2\%,\;33.2\%,\;19.6\%,\;and\;16.9\%$ respectively. The most preferred casual wear style by male college students was determined as basic casual wear, followed by adult casual wear, fashionable casual wear, and sporty casual wear. Other than the most preferred style, basic casual wear, by every group, the preference of casual wear styles differed among 4 lifestyle groups.

Dry sliding wear resistance of DLC coated silicon disk with different surface roughness has been evaluated using a ball-on-disk sliding tester. It was found that the transfer layer formed on steel ball produced a low friction regime and the formation of transfer layer was more active with increasing the substrate surface roughness. Wear life of DLC coating was increased as increasing the real area of contact.

Today, digital technology is extending its influence to fashion design, which is closely related to people's lifestyle. In order for people to access information all the time, every place, people have to wear these devices all the time, every place. Intelligent wear allows people to communicate with their own body, other persons or surrounding real-time. The purposes of this study are to define 'Intelligent wear' by looking through the similar terms of intelligent wear on related fields, to analyze characteristics of intelligent wear and to provide not only theoretical data but also, practical data far product development on both functional and aesthetic sides. In this study, usefulness provided by intelligent wear were identified in the concept of instrumental & expressive function. For the aim of the study, literature and case study were considered at the same time. The conclusions are as the following. The characteristics of intelligent materials were found to be information, intelligence and protection, the characteristics of intelligent manufacture were combination and virtual reality. And The characteristics of intelligent products were multi-function, transformation, camouflage. Integration of operability function extends human ability and the area of human activity, entertainment, and communication, and provides convenience. Consequently, development of intelligent wear should promote through not only computer engineering but also, connection to other fields. Most of all, there is a need for active research in clothing design and the fashion design since intelligent wear is after all, clothing.

Today, many pregnant women also advance up the business ladder and remain very active. They are consequently increasingly aware of the clothes they can wear. Despite these social changes, maternity wear has not been specially designed to satisfy the consumer's demands. From this, the purposes of this study are to investigate the current status of maternity wear and the apparent buying trends of pregnant women through a customers' opinion survey and interviews for the future maternity markets. In summary, the survey and interviews illustrate some important points which are that: Firstly, not all pregnant women buy maternity wear. Some pregnant women said they couldn't find enough difference in maternity wear prices even though they would like to buy some, commenting that maternity clothes were too expensive for such a short period of time. Also some already had maternity wear from a previous pregnancy, or had been passed on from friends and family. Secondly, on the other hand, many respondents were strongly concerned with style and quality rather than price because they agreed that there were not enough suitable maternity clothes for work and special occasions. Therefore some respondents would buy a maternity outfit for a special occasion. It also indicates that for a particular time, place or occasion like a party, wedding or other celebration, some respondents would buy a special outfit to make themselves feel good. Finally, according to the survey, the most important design concept is for wearable designs which change with the body during pregnancy; followed closely by designs which are able to be re-used when the pregnancy has finished. Nowadays, as recycling and saving resources are the biggest issues, if maternity manufacturers are encouraged to develop new products incorporating these new design concepts, more maternity markets will be developed to buy maternity wear.

As the engine design change to get high efficiency and performance of commercial diesel engine, surface wear of the cam follower becomes an important issues as applied load increasing at the contact face between cam follower and cam. Purpose of this study is the developing of the ceramic cam follower made of silicon nitride ceramic which is more wear resistant than the cast iron and sintered cam follower. Ceramic cam follower was made by direct brazing of thin ceramic disk to steel can follower body using active bracing alloy. Effect of joining condition on the interfacial phases and joining strength wer examined at bvarious joining temperatures, times, and cooling rates. Crowning resulted from the difference of thermal expansion coefficient after direct brazing without using any stress-relieving inter layer was measured. Interfacial phases are mainly titanium silicide and titanium nitride which are the products between active metal(Ti) in brazing alloy and silicon nitiride. Maximum joining strength of the ceramic metal joint, measured by DBS method, was 334MPa. Crowning(R) of the prototype ceramic cam follower was 1595mm. As machining for crowning is not necessary, production cost can be reduced.

This study selected fashion brands claiming to advocate feminism to analyze their characteristics and female images. For the study's data, online foreign feminist fashion brands were sifted from March 2017 to January 2018 and 28 clothing brands were selected. The study's results show that feminist fashion brands aim at the demassification and individualization of fashion products to be more inclusive of individuals' physical characteristics and diversity. Additionally, feminist brands entice consumption through communication and participation in online communities and through the value of social coexistence. The essential female image produced by feminist fashion brands deconstructs a socially idealized female image and expresses a sense of self-body positivity. In turn, the concept of self-body positivity is communicated through natural images of independent women with distinct identities based on differences in race, culture, and sexual orientation. Moreover, feminist fashion brands produce social images featuring independent women using active wear to engage in social activities. Casual wear is also used to reflect active women, while mannish looks and power suits express women's social status and professional abilities. Ultimately, these offer functionally active and rational images, combined with female images featuring long hair and makeup. Yet another type of female image seeks to create a new vision of women as diverse due to their various cultures, countries of origin, races, and individual tastes. These new images express women's physical differences, distinct identities, and diversity while simultaneously deconstructing pre-existing forms of clothing.
