  • The Effects of Self-Esteem and Sociocultural Attitude toward Appearance on Clothing Behavior. The purpose of this study was to investigate to relation between self-esteem and sociocultural attitude toward appearance and clothing behavior i.e. individuality/self expression, body improvement, social approval, sex appeal. Measurements were included Rosenberg's self-esteem, Thompson's sociocultural attitude toward appearance questionnaire and clothing behavior. The data were collected from 498 female university students in Seoul and Kyongki Province. The collection works were undertaken between the 15th of June and 30th of June, 2001, The data were analyzed using factor analysis, reliability test, analysis of variance, and multiple regression analysis. The results of this study were as follows : 1) Three dimensions of sociocultural attitude toward appearance were identified: internalization, social awareness, and concrete awareness. 2) Self-esteem and internalization of sociocultural attitude toward appearance had an effect on clothing behavior i.e. individuality/self expression, body improvement, social approval and sex appeal. Social awareness of sociocultural attitude toward appearance had an effect on body improvement, social approval, and sex appeal.

  • The purpose of this study was to find out the source of information and clothing benefits of female university students according to their shopping orientations. 340 female students living in Seoul were surveyed and the following results were found: Female students were divided into recreational shoppers and convenience shoppers according to their shopping orientations. Recreational shoppers exhibited interest in self-improvement, individuality, economy, and convenience shoppers in practicality of clothing benefits. Recreational shoppers focused higher value on gathering information than convenience shoppers and prefer information they gain in store display and mass communication media. Recreational shoppers have higher value on self-actualizing than social affiliation value. The findings indicate that shopping orientation can be used effectively to segment the female university students market and the finding of this study contribute to the development of strategies for clothing producer or retailer to provide a strong means to satisfy their shoppers' needs.

  • The purpose of this study were; (1) to investigate the relationship between the general values and 3 aspects of clothing behaviors. (2) to investigate attitudes toward Korean clothing between students and their mothers. General values were measured by the Allport-Vernon-Lindzey Study of Values(Part 1 only), which determines relative prominence of six basic values. Three aspects of clothing behaviors were assessed by statements dealing with satisfaction, exhibitionism, and fashion. Korean clothing measures consisted of statements dealing with positive and negative attituded toward psychological and practical aspects. The samples consisted of 200 students(student group) and 100 mothers (mother group) in Daejon. The data were analyzed by correlation and t-values. The results obtained through this study were as follows: 1) Positive relationship were found between: (1) Aesthetic value and the exhibitionism of clothing, (2) Aesthetic value and the fashion of clothing. Negative relationships existed between (1) Theoretical value and the exhibitionism of clothing, (2) Economic value and the fashion of clothing, (3) Social value and the fashion of clothing. 2) Significant differences were found between two groups(students and their mothers) : Economic, aesthetic, and political values as well as exhibitionism and fashion in clothing behaviors. 3) In general, highly positive attitude toward Korean clothing was found on psychological aspect, while highly negative attitude was found on practical aspect. Significant differences were found between two groups; (1)‘Graceful’of psychological aspect and‘economic’,‘inexpensive’of practical aspect in positive attitudes toward Korean clothing, (2)‘Unsuitable to current life style’,‘not modern’and‘not beautiful’of psychological aspect in negative attitudes toward Korean clothing.

  • 최근 3D 프린팅 기술은 산업적인 응용분야의 확대를 위해 다양한 복합소재의 적용이 연구되고 있다. 기존 3D 프린팅 기술은 대부분 플라스틱 소재 위주로 개발되어 왔으며, 세라믹 소재의 경우 물리적, 화학적으로 우수한 물성을 가지고 있음에도 불구하고 상대적으로 3D 프린팅 적용을 위한 연구개발이 초기 단계에 머무르고 있다. 본 연구에서는 DLP(digital light processing) 3D프린팅 공정에 적용을 위해 다양한 입도의 실리카를 기반으로 광경화성 복합소재를 합성하였다. 다양한 적층 방식의 3D 프린팅 기술 중에서 DLP 3D 프린팅 방식은 광경화성 수지에 빛을 조사하여 3차원 기물을 제조하는 기술로 정밀도가 우수하고 다양한 소재 적용성이 높다. 합성된 실리카 복합소재의 충진율에 따른 유변학적 거동분석을 통하여 DLP 3D 프린팅 적용가능성을 확인하였고, 원활하게 적층조형이 잘 이루어지는 것을 확인하였다. 3D 프린팅된 시편의 인쇄 정확도는 디자인과 약 3 % 미만의 차이를 나타내었고, 실리카 입자의 충진율이 80 wt%일 때 34.3 MPa의 강도를 나타내었다.

  • Microstereolithography has evolved from the stereolithography technique, and is also based on a light-induced layer-stacking manufacturing. Integral microstereolithography is proposed for building a 3D microstructure rapidly, which allows the manufacture of a complete layer by one irradiation only. In this study, we developed the integral microstereolithography apparatus based on the use of $DMD^{TM}$ as dynamic pattern generator. It is composed of Xenon-Mercury lamp, optical devices, pattern generator, precision stage, controllers and the control program. Also, we estimated curing characteristics in photopolymer. The relationship between the viscosity of diluent-oligomer solutions and curing width, irradiation time and curing property has been studied.

  • A single gap transflective liquid crystal display(LCD) driven by fringe electric field in the transmissive(T) region and vertical electric field in the reflective(R) region was designed. Because the pretilt angle is formed in $53^{\circ}$ through polymerization of an UV curable reactive mesogen(RM) monomer at the surface, the effective cell retardation $(d{\Delta}n_{eff})$ value of the R region becomes half of that in the T region where the LCs are homogenously aligned. Consequently, a transflective display driven by a vertical and fringe electric field with a single cell gap and single gamma curves is realized.

  • Sagnac 형태로 변형된 Mach-Zehnder 간섭계(SMZI)는 모든 광경로가 동일한 광부품을 서로 공유하기 때문에 위상 흔들림을 최소화할 수 있는 안정된 간섭계이다. 본 연구에서는 단일광자 수준까지 감쇄시킨 레이저 광과 제 2형의 매개하향변환에서 발생한 편광 상관관계가 있는 광자로부터 준비된 단일광자를 이용한 간섭실험에서 매우 안정된 간섭무늬를 관측하였다. SMZI의 위상은 약 ${\pm}0.18$ rad으로 안정적인 반면에 보통의 MZI는 ${\pm}1.02$ rad의 위상 요동을 나타내었다.
