Conjoint analysis estimates how much each of the attributes is valued on the basis of the choices consumers make among product concepts that are varied in systematic ways. The purposes of this research were to evaluate the relative importance of each fabric constituent characteristic for the consumer's utility or preference, to compare with the relative importance between the trained and the untrained panelists, and to identify the combinations of the constituent characteristic of knit fabric which offer consumers greater utility. Conjoint analysis was conducted using data taken from 54 trained and 54 untrained panelists, who rated preference for 12 different knit fabrics. The stitch length had a greater effect on knit fabric preference than the mixture ratio of fiber. There was no difference on effect of knit constituent characteristics for preference between the trained and the untrained panelists. Total, trained and untrained group preferred a knit fabric that had a higher acrylic mixture ratio and a short stitch length.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. This Single PPM Quality Innovation Movement program was conducted to realize the anticipated results not only due to management result level's increasing, but also the company's confidence and competitiveness. This study attempted to find the mutual influences on the participation of the constituent members, satisfaction of the constituent members and results of the management from Single PPM Quality Innovation Movement. The reliance analysis for the measurement material on the questionnaire was verified by Cronbach's alpha coefficient. Participation of the constituent members, satisfaction of the constituent member and result of the management, the influences upon Single PPM improvement degree level were verified through the structural analysis by using SPSS statistic package. The influence evaluation among the groups was evaluated by the structure equation.

이 논문은 한국어 문장을 대상으로 구문요소의 전치를 기반으로 한 문서 워터마킹 방법을 제안한다. 한국어와 같은 교착어는 구문요소의 순서가 자유롭기 때문에 구문 트리 기반의 자연어 워터마킹을 위한 좋은 환경을 제공한다. 본 논문에서 제안하는 자연어 워터마킹 방법은 7단계로 구성되어 있다. 첫째, 문장의 구문분석을 수행한다. 다음으로, 구문요소가 해당 절의 범위 안에서만 전치되도록 범위를 한정하기 위하여 구문 트리로부터 각 절을 분할한다. 세 번째로, 전치를 위한 목표 구문요소를 선택한다. 네 번째, 목표 구문요소의 전치 후에도 문장의 의미나 문체의 변화가 최소화되도록 가장 자연스러운 전이위치를 결정한다. 그 후, 목표 구문요소에 대한 워터마크 비트를 삽입한다. 여섯 번째 단계로, 워터마크 비트가 목표 구문요소의 전치 방향과 상응하지 않으면 구문 트리에서 목표 구문요소를 전치한다. 마지막으로 변환된 구문 트리에서 워터마킹된 문서를 얻는다. 실험 결과를 통해 본 논문에서 제안한 방법의 적용률은 91.53%이고, 최종 워터마킹된 문장들 중 부자연스러운 문장의 비율은 23.16%로서 기존 시스템들보다 좋은 결과를 보여준다. 또한 워터마킹된 문장이 원시 문장과 같은 문체를 유지하고, 의미적인 왜곡없이 같은 정보를 나타내고 있다.

This study first defines the fashion convention industry as an idea that includes international conventions, exhibitions and collections mainly dealing with fashion (fabric·material, clothing·fashion, and machinery·equipment). It then infers constituents of the industry based on preceding studies on service quality and satisfaction, and analyzes their importance and the structural relation between constituent performance, satisfaction and ex post behaviour. Also it analyzes perception difference of the organizer and participators on constituent importance, performance, and satisfaction. In the survey, a total of 500 questionnaires were distributed to the organizers and participants of 2001 Seoul Fashion Week, and among them, 259 questionnaires from the participants and 18 from the organizers were used as data for the demonstrative analysis. LISREL 8 program and SPSS WIN V. 8.0 were used for a statistical process of collected data.

This study attempted to investigate the perspective of the skirts of male and female students by analyzing the differences in image evaluation according to the constituent elements (type, length, and wearing method) of men's skirt designs in modern fashion. The study included 109 male and female college students from Generation Z residing or whose life center was in Gwangju Metropolitan City, to evaluate 12 images depicting types of men's skirts. First, the constituent image evaluation factors according to the constituent design elements of men's skirts were analyzed. Second, the differences in each constituent image evaluation factor based on the constituent design elements of men's skirt designs were analyzed. Third, the gender-based differences in image evaluation by men and women concerning the constituent design elements of men's skirt designs were analyzed. The analysis included relatively more women than men. The results of the image recognition dimension included the following categories: "attractive image," "evaluable image," "gender image," and "personality image." In modern fashion, skirts are used to express the diverse personalities of men's fashion. Thus, they are used beyond the stereotype of women's clothing, toward expanding and diversifying the image of men's clothing through mixing and creating a dichotomous image of men and women. It can be used as a design that suggests a gender-fluid image.

A series of alternating and alternating block copolycarbonates containing the constituent groups of polysulfone was synthesized through a multi-step solution condensation method. For the regulation of block length, monodisperse oligomers were prepared by using a large excess of the bisphenols and were subsequently incorporated into the copolymer chains. Separating the unreacted bisphenols from the oligomers by dissolution/precipitation steps took advantage of solubility differences. The structures of the monomers, oligomers, and copolymers were characterized and confirmed by GPC, NMR spectroscopy, mass spectrometry, and elemental analysis. Monodispersity of the oligomers, which is critical for control over the block length in the copolymers, was confirmed by GPC and mass spectrometry. Of the two constituent groups of the polysulfone, the sulfone linkage stiffens the polycarbonate copolymer chain, while the ether linkage softens it.

Among various fuel cells, solid oxide fuel cells (SOFCs) offer the highest energy efficiency, when taking into account the thermal recycling of waste heat at high temperature. However, the highest efficiency and lowest pollution for a SOFC can be achieved through the sophisticated control of its constituent components such as electrodes, electrolytes, interconnects and sealing materials. The electrochemical conversion efficiency of a SOFC is particularly dependent upon the performance of its electrode materials. The electrode materials should meet highly stringent requirements to optimize cell performance. In particular, both mass and charge transport should easily occur simultaneously through the electrode structure. Matter transport or charge transport is critically related to the configuration and spatial disposition of the three constituent phases of a composite electrode, which are the ionic conducting phase, electronic conducting phase, and the pores. The current work places special emphasis on the quantification of this complex microstructure of composite electrodes. Digitized images are exploited in order to obtain the quantitative microstructural information, i.e., the size distributions and interconnectivities of each constituent component. This work reports regarding zirconia-based composite electrodes.

In the present paper, glass fibers are substituted partially with monofilament fishnet and polyester matrix for making the composites. The composite specimens were prepared in accordance with ASTM for analyzing the flexural strength and dynamic mechanical properties. Furthermore, machinability revealed the interaction of glass fiber and partial substituted monofilament fishnet fiber with the matrix. Fiber pullouts on the fractured specimen during the physical testing of the composites are also investigated by COSLAB microscope. The results reveal that the fishnet based composites have appreciably higher flexural properties. Furthermore, the glass fiber, woven roving and fishnet composite has more storage modulus and significant mechanical damping. The composite specimens were fabricated by hand lay-up method. Hence, these composites are the possible applications to develop the value added products. The results of this study are presented.
