This study was attempted to be a help in estimating changes of men's fashion in sociocultural environment by examining the diversified trends of domestic men's fashion through literature review, fashion collection analysis and questionnaire in various aspects. For data collection in this study, questionnaires were used, and these were corrected and supplemented after preliminary survey for male consumers from September 2009 to March 2010. Among total 460 copies, 431 copies were used in final analysis. First, among typical factors of changes in image of men's fashion, change of sexual role was shown as the most important factor. Contrary to men of the past, modern men are actively taking care of their appearance with changes of social values, which indicates that viewpoints on men have become flexible, such that the image of beauty does not apply just to women. Second, analysis on factors of image changes in men's fashion by age revealed that high mean values were obtained in factors of change of sexual role and trend with difference between groups, and factors of expression of individuality were highly rated without remarkable difference, and aesthetic factors were poorly rated without significance. Third, analysis on preference for formative characteristics of the Metro Sexual showed that feminine materials were negatively rated, and analysis on wearing experience revealed that several items become popular, indicating that wearing experiences are increasing in various areas. This study suggests a new viewpoint of cultural sexual consciousness of the youth that is continuously changing, and is meaningful in understanding emotional and rational lifestyle and cultural style of Metro Sexual, a recent phenomenon of men's fashion.

Objectives: The study was designed to assess the trends of the incidence of HIV among young people and their sexual risk-taking behaviors by gender in Korean college students. Methods: The cross-sectional study was used from college students from selected 60 among 208 4-year colleges and universities in 9 provinces and Seoul. A self-reported anonymous questionnaire administered and completed to a national representative sample of 4-year college students from May 15th to June 14th in 2003. We analyzed 2,385 cases. The overall response rate was 82.0%. Results: After controlling age effects, male students were more likely to be sexually experienced than female students(40.0% vs. 8.1%), OR=5.5, p<.000. The proportions of 19 years and before reported for initiation of sexual intercourse were 18.6% for males and 3.2% for females. Males reported significantly younger ages than females at initiation of sexual intercourse(p<.01). Only 14.8% of current sexually active subjects reported consistent use of contraceptive methods. After controlling age effects, male students reported a higher proportion of sexually experienced respondents with one or more casual partners(excluding a formal partner) during the last 12 months than women(38.8% vs. 22.2%), OR=2.2, p<. 05. Conclusion : This study can conclude that although males students initiate sex earlier and have higher percentage of sexual experience, the percentage of sexually experience female students has risen rapidly compared to the past. This data revealed a number of young people were at risk for HIV infection. Both genders are equally likely to have engaged in inconsistent condom use even though when they have a sex with an unknown partner. These findings suggest that practical sex education focused on using condom use should have been included in the school curricular. Educational and community interventions need to prevent sex-related problems.

The recent concept of kitchen is likely defined as "Kitchen Culture" including the function of living room where all families make a conversation as well as a dinner, and it is becoming another type of the residential environment, deviating from the stereotype as only cooking area. Particularly the comfortableness of living room is closely associated with a receipt function of kitchen, and the sort & dimension & size of furniture and diversity of shapes playa more meaningful role for improving our life standard & comfortableness compared with the past, nevertheless this receipt study is carelessly handled in the first phase of construction. This Study is focusing on understanding the modern concept of kitchen where the open space concept is being introduced as more reasonable space concept, and on suggesting a solution for receipt-function of the modern kitchen concept connected with "L-D-K (Living room - Dining room- Kitchen)" space idea. In the Chapter 2 the concept of receipt and function of kitchen, the wide variety of kitchen utensils was checked up, and in the Chapter 3 the change of trends of kitchen area & receipt space was considered, and finally in the Chapter 4 the modern concept of kitchen was presented, by instancing overseas examples with receipt planning. As a consequence, the alternative of the receipt in the modern kitchen is to install an Ireland table or another type of receipt-available table (lower furniture) in the dead space between kitchen & living room for motivating smooth communication and convenient receipt, and that is the trend nowadays. Kitchen desires a rapid change. Through this kind of study it should be more researched that kitchen is not an independent space any more and lies in the mutual connection of L-D-K.

Generally, Interior design understood as shapes, lines, spaces, tones, quality, and principal. And people research these with a study of formative approach. The six elements of above categories are basis of expansion for the various designs. In this study, the represented design language is extracted by the basic 6 stages and re-divided into classes. This study presented by the Kobayashi-scale image of the current trends in the assignment to examine the cultural, functional, sensory vocabulary, three elements were classified by the assignment about 2008~2009 international fair by trend and design direction for the image. If we look into the categorized format of the design, it reflects mixed culture with emotional approach and shows direction of design constantly. Especially, compared to the year 2008, the design of year 2009 has tendency as an emotional translator regarding the verbal expression. In other words, it becomes more concrete to express the design of emotions for human beings. In addition, design shows detail of its flow with outcomes of past leading trend which was re-created shape. On the other hand, undeveloped cultures such as folk, historical, and unique cultures attract design leaders as it is. This research would make good relationship between designers and customers regarding the newly started international trend of design. Hereby I research with the method to reclassify the image of vocabulary from the image scale extract. It remains as a task to resolve ambiguous, complex and neutral expression for better understanding and definite analysis method to the public.

In the 1970's the Interior Design Associations was established and the activity of youth designers who werecalled the "first generation of Korean interior designers" were created. This study is aimed to analyze characteristics and trends of commercial interior design in the 1970's. The design methods include the documentary research and the actual proof research conducted. The frames of analysis were made by the background theories about Korean interior design, and the annual case studies were analyzed and estimated according to the design types. The design types were analyzed by the geometrical simplicity research, the romantic emotional expression, the Korean identity expression, the machine technical asthetic expression and the eclectic style with western classics. In the early 1970's, the abstract, brief, and simple expression were presented most frequently by the geometrical form and the repetition of the pattern. From the mid-1970's the romantic and emotional atmosphere of the youth culture that was popular at that time were expressed as vernacular design by the rough finishing of the natural materials such as plaster, brick, and wood floorings etc. The space such as a Korean food restaurant relates to the Korean traditional culture aims to be different through the expression by the Korean traditional patterns, furniture, and materials. In the late 1970's the metals and glass were used for the expression of the machine aesthetic form but was not popular because of the rare application. The type that revived the past western traditional form was presented by using the arch, dome, and the curved and luxurious moldings.

This study is designed to analyze the trends of professional services in Landscape Architecture during the past 5 years(1987-1991) in Korea. The data were collected from 1,117 projects from 56 engineering and landscape architecture firms. The findings are summarized as follows: 1) The projects have been increased annually by 19 percent in numbers and by 47 percent in money terms. 2) The main sources of projects are local governments and corporations. However the private sector comprise 31 percent in projects number and 46 percent in money terms. 3) The public park and tourism site development comprise a half of the projects. Recently recreational forest, golf, amusement and large housing site development have increased very rapidly. 4) In terms of workscope they are devided by 'complex' project which include extensive engineering works and 'simple' project which contain mostly planting design. The former include receational project with average 5 or 6 months contract period, and the later include housing and building site design with 2 or 3 months period. 5) Two types of consulting firms are typical. One is comprehensive engineering firms with urban planning section and few landscape section. The other is specialized professional firms with urban planning or landscape architecture. 50 percent of the project was done by comhensive engineering firms and 60 percent was done by urban planning section. The implication of these findings are broad: Firstly, We have to meet the demands in private secter mostly in recreation and leisure related projects. Secondly, landscape architects and project managers need more professional skills and coordination ability to deal with 'complex' projects. Thirdly, to enhance the quality of professional services it is required to have enough work time and higher service fee through legal and institutional enforcements.
