소프트웨어 품질의 중요성이 높아지면서 고품질의 제품을 만들기 위한 노력이 지속적으로 이루어지고 있다. 고품질 소프트웨어는 적은 노력과 비용으로 유지보수가 가능하므로 품질 향상의 중요성은 간과할 수 없는 중요한 문제이다. 현재, 소프트웨어 제품의 품질평가를 위한 프로세스로서 ISO/IEC 14598이 있으며 이 방법을 활용한 품질평가 체계와 메트릭스의 구축을 통해 품질향상을 도모하려는 연구가 활발히 진행되고 있다. 본 연구에서는 개발자가 소프트웨어 제품평가를 위해 적용할 수 있는 품질평가 프로세스를 제안하고 개발자의 제품평가 방법에 관해 기술하였다.

XML이 인터넷을 기반으로 하는 정보교환의 매개체로써 다양한 응용분야로 확산됨에 따라 XML 데이터로부터 구조정보를 추출하고 효율적으로 저장하며 관계형 데이터베이스로부터 추출된 데이터를 XML 문서로 생성하는 시스템이 요구되어진다. 기존의 관계형 데이터베이스 벤더들이 XML을 처리하기 위해 시스템을 확장하기는 하지만 이러한 시스템들은 시스템과 플랫폼에 종속적이라는 단점을 가지고 있다. 이 논문에서는 이러한 문제점을 해결함과 동시에 DTD와 관계형 스키마가 존재하지 않는 환경에서 XML문서를 효율적으로 저장하고 XML_QL을 지원하는 Amoeba 시스템을 소개한다.

It is so difficult to small amounts of two or more fluid species into single in microchannel because flows are usually laminar. In this regard multilamination micro mixer including recirculation zone is presented. Alternating feed micro channels make multilamination and converging-diverging channels form recirculation zone. Multilamination with geometric focusing decreases diffusion path ana recirculation zones make vortex. In this paper flow patterns and mixing properties of multilamination micro mixer including recirculation zone were investigated by Computational Fluid Dynamics (CFD). The CFD results provided qualitative information on mixing.

This paper is concerned with the dynamic modeling and controller design for a cylindrical shell equipped with MFC actuators. The dynamic model was derived by using Ravleigh-Ritz method based on Donnel-Mushtari shell theory. The boundary conditions at both ends were assumed to be shear diaphragm. To verify the theoretical results, a cylindrical shell structure made of aluminum was built ana tested by using impact hammer. Experimental results show that there are little discrepancies compared to theoretical results because of the boundary conditions at both ends. The MFC actuators were glued to the cylindrical shell in longitudinal and circumferential directions. The PPF controller were designed for lowest two modes and applied to the MFC actuators. The experimental results show that vibrations can be successfully suppressed.

The purpose of this study was to investigate the relationship between three aspects of clothing behavior ana three personality traits. Personality traits were measured with Chung's Personality Scale. 1 The questionnaire measuring clothing behavior consisted of items designed to assess clothing conformity, importance, and self-concept regarding clothing, This questionnaire was composed of items designed for this study in addition to items selected from questionnaires of such researchers as Sin, Lee, Chung, creekmore, Cheek, and Kim. These questionnaires were administered to 323 high school girls in Seoul. Statistical analysis consisted of correlation and t-test. The results were : 1) Dominance was positively related to self-concept regarding clothing and negatively related to clothing conformity. 2) Emotional stability was positively related to clothing modesty. 3) Sociability was positively related to self-concept regarding clothing. 4) There was no significant difference in clothing behavior between early adolescents and late adolescents.

The purpose of this study was to see if a relationship existed between the level of modesty in clothing ana clothing values of male and female university students. The difference between sex was also investigated. A questionnaire composed of Engelbrecht's 'Modesty in relation to women's dress' and Creekmore's 'Measure of eight clothing values' was administerd to 1, 100 students and the data from 888 respondents (466 male, 422 female) was analyzed by t-tests. findings were as follows : 1. There was no significant difference between male and female in the level of modesty in clothing. 2. Each score of sensory, economic. social, theoretical, and religious clothing value of male students was significantly high and exploratory, aesthetic and politicalclothing value score of female students was significantly high at the .005 level of confidence. 3. Each score of sensory economic, theoretical and religious clothing value was significantly high in Modest group and exploratory, aesthetic and political clothing value in Immodest group was significantly high at .005 level of confidence.

This paper presents the method for structure borne noise analysis of a flexible body in multibody system. The proposed method is the superposition method using flexible muitibody dynamic analysis and finite element one. This method is executed in 3 steps. In the la step, time dependent quantities such as dynamic loads, modal coordinates ana gross body motion of the flexible body are calculated efficiently through flexible multibody dynamic analysis. And frequency response functions are computed using Fourier transforms of those time dependent quantities. In the 2$\^$nd/ step, acoustic pressure coefficients are obtained through structure-acoustic coupling analysis by finite element analysis. In the final step, frequency responses of acoustic pressure at the acoustic nodes are recovered through linear superposition of frequency response functions with acoustic pressure coefficients. The accuracy of the proposed method is verified in the numerical example of a simple car model.

Soybean lipoxyeenase isozymes were isolated from acetone-defatted soybean seeds(Glycine max [L.] Merr. variety AmSoy) by ammonium sulfate fractionation, eel filtration, and ion exchange chromatoeraphy. The final preparation of lipoxygenase-1 and -2 obtained was 19- and 32-fold purified, respectively, to the crude extract. But a considerable loss of total enzyme activity occurred during purification. On 7% polyacrylamide gel electrophosis at pH 9.0, employing lipoxigenase specific staining technique, lipoxyeenase-1, -2, and -3 showed distinctive Rf values of 0.38, 0.29, and 0.33, respectively.

This paper is to test the modulating effect of organizational culture on the relationship between personality and incremental innovation, and study of the relationship between incremental innovation and service Quality in service industry. Based on 507 data gathered in service companies in Korea, analysis results and showed that procedural, interactional, and innovative culture have affirmative relation with incremental innovation. Therefore innovative culture appeared to have some modulating effect on the relationship between personality and incremental innovation. And ana-lysis results of relationship between incremental innovation and service quality are followed; service innovation and process innovations showed positive effects except some operation innovations.

I introduce the Flexible Dam Operation (FDO) and some of sediment control techniques In dams which are implemented as trials to avoid or reduce environmental impact of dams on the downstream reaches. The FDO is a dam management method to improve river environment in the downstream reaches by means of the flushing flow, the maintenance flow and so on utilizing a vacant portion of capacity for flood control without interrupting prime flood control function during the rainy/typhoon season. It Is suggested by the guideline of the FDO that EDO should be implemented regularly after the trial for about three years. The basic conception of the FDO is described here. The example of excavation of deposited sediments in check dams and placement of sand ana gravel immediately downstream of the dams and the example of coordinated sediment flushing are described as some of sediment control techniques in dams. Now they are at the stage of experiment and trial. Therefore, it is important to increase examples and establish the technical methodology and the environmental evaluation method for them.
