In conventional probability-based quality evaluation of products with qualitative characteristics, many factors that affect the evaluation are not easily represented quantitatively, because the relation between reliability of human evaluator and each of these factors is not clear. In order to evaluate the quality of product with qualitative characteristics quantitatively, in this paper, the relation is represented as the shape of possibility distribution function of fuzzy set on the interval [0,1]. Furthermore, fuzzy reasoning is used to obtain the estimates of quality characteristics. And, it is supposed that many quality characteristics affected by the above factors are connected with the final characteristic through hierarchical structures. Finally, using the estimates gained from the final evaluation, qualitative characteristics are evaluated by use of concept of pattern recognition.

This paper is to test the mediating effect of superior trust on the relationship between organizational justice and service quality in service food industry. Based on 302 data gathered in western Kangwon area, analysis result showed that procedural, interactional, and distributive justice have affirmative relation with trust, and also trust has close relation with service quality. Therefore, trust appeared to have fully mediating effect on the relationship between organizational justice and service quality.

We study the numerical analysis for the Cahn-Hilliard (CH) equation using the decoupled projection (DP) method. The CH equation is a fourth order nonlinear partial differential equation that is hard to solve. Therefore, various of numerical schemes have been proposed to solve the CH equation. To verify the relation of each existing scheme for the CH equation, we consider the DP method for linear convex splitting schemes. We present the numerical experiments to demonstrate our analysis. Throughout this study, it is expected to construct a novel numerical scheme using the relation with existing numerical schemes.

In this paper the recent studies of digital governor for the Diesel Engine in Korea is summarized and that of usage in the marine and land field as of power plant is analyzed for the interest and development of the enterprise with relation with relation to this industrial part. Our investigation shows that until now the studies on the digitl governor are mainly carried out in KMU and land usage for the power plants is increased gradually because reliance of digital governor is improved and system for the maneuvering and monitoring the plants is computerized.

본 액화 실리콘 고무는 내열성 및 내화학적 우수성으로 전자 제품 및 다양한 제품에서 활용되고 있다. 하지만 초탄성 재료는 일반 금속재료와 다른 특성을 보인다. 초탄성 재료는 하중과 변형이 비선형 관계를 보이는 대변형 범위에서도 탄성거동을 나타내는 특성을 지니며, 비선형, 비압축성 및 대형의 특성을 지니고 있다. 이러한 특성 때문에 제품을 설계 및 생산 하기위해는 기능적 측면을 고려한 소재의 특성에 대한 물성 확보가 반드시 필요하기 때문에 현장에서 많은 어려움이 있다. 본 논문에서는 자동차용 방수커넥터 설계를 위해 소재의 인장, 압축 시험으로부터 구한 하중-변형관계를 이용하여 이를 유한 요소 해석에 적용한 결과를 비교하였으며, 해석결과와 제품의 성능 테스트 결과를 비교하여 방수커넥터용 씰의 경우 어떠한 소재특성을 적용할 경우 유용한 결과를 도출할 수 있는지를 확인하였으며, 이를 통해 제품 개발에 유용성을 확인하였다.

This article is concerned to investigate the changing nature of the role of the state in relation to industrial policy to foster the IT industry in the Republic of Korea. In doing this, it has started with economic globalization introduced to the Korean political economy since the late 1980s. It has identified in what ways the state responded to the change, and to what extent the role of the state has fundamentally been changed in the context of policy mechanism in the process towards facilitating the IT industry in Korea. In addition, it presented how the state played a role in skill formation in relation to the industrial policy. In consequence, the role of the Korean state in fostering the IT industry has fundamentally changed from that as the developmental state in the industrialization process. In the process, that the strategic co-ordination role of the state and relations between the state and private capitals and societies are very significant to achieve the economic goal is presented as results, as well as some future tensions that would encounter in the way of charting the current policies.

Constructing the influence lines of forces of statically indeterminate structures is a traditional issue in structural engineering and mechanics. However, the existing kinematic method for establishing these force influence lines is an indirect or mixed approach by combining the force method with the theorem of reciprocal displacements, which is yet inconsistent with the kinematic method for statically determinate structure. This paper proposes the direct kinematic method in conjunction with the load-displacement differential relation for exactly constructing influence lines of reaction and internal forces of indeterminate structures. Firstly, through applying the principle of virtual displacement, the formula for influence lines of reaction and internal forces of indeterminate structure via direct kinematic method is derived based on the released structure. Then, a computational approach with a clear concept and unified procedure as well as wide applicability based on the load-displacement differential relation of beam is suggested to achieve conveniently the closed-form expression of force influence lines, and exactly draw them. Finally, three representative examples for constructing force influence lines of statically indeterminate beams and frame illustrate the superiority of the proposed method.

The purpose of this study is to verify the role of moderating effect of pay system on the relation between organizational justice and employee's pay level satisfaction. By default, it would be a justice find out a positive impact on pay levels satisfaction members feel. It will examine the mediating effect of the wage system the main purpose of this study is to prove their relationship. A survey was conducted to examine the role of moderating effect of pay system on the responses of 218 employees. sex, education, status, and service type were chosen as control variable, and the regression model which treated the distributive justice and procedural justice as independent variable was set. A pay system was supposed as moderating variable of the relation between organizational justice and pay level satisfaction, In addition the pay system have a dummy variable (if pay system is lower than the average, pay system is 0, else pay system is 1). The result showed that the relation of organizational justice and pay level satisfaction are significantly unique. This means that pay system moderates the relation of organizational justice and pay level satisfaction. These results are different from the prior researches which had treated pay system as mediative variable of organizational justice and pay level satisfaction. This difference may be from the property of attitude variable. For example, pay satisfaction is individual-based attitude. Moreover, organizational committment has the instrumentality for future reward, while pay satisfaction does not. The future study should consider the properties of these variables and other employee's attitude variables.
