A vague graph is a generalized structure of a fuzzy graph that gives more precision, flexibility and compatibility to a system when compared with systems that are designed using fuzzy graphs. In this paper, we define two new operation on vague graphs namely normal product and tensor product and study about the degree of a vertex in vague graphs which are obtained from two given vague graphs G₁ and G₂ using the operations cartesian product, composition, tensor product and normal product. These operations are highly utilized by computer science, geometry, algebra, number theory and operation research. In addition to the existing operations these properties will also be helpful to study large vague graph as a combination of small, vague graphs and to derive its properties from those of the smaller ones.

Human, physical damage is happened frequently to consumer's safety accident by product defect on modern industrial society. Accordingly, advanced nation including the United States of America enforce product liability law and is protecting consumer more actively from danger of product defect. Our country(Korea) may enforce product liability law since July, 2002, and if business does not grope effective confrontation way about PL, capital strength weak smaller enterprise and venture business corporation's competitive power may affect much corporation's competitive power enfeeblement and survival. This research supplement based on induction and operating QMS in smaller enterprise essential factor that corporations must equip according to product liability law enforcement. And we present integration quality management system model of Product liability to do so that smaller enterprises may can cope effectively at force of Product liability law.

Product liability(PL) is the producer's compensation to customers for damage incurred by product defects. This paper studies on the organizational culture, promotion process, system construction, system level, product safety review, product safety assurance, system operation, and its effectiveness and necessity of recognition for the PL system of small and medium-sized firms in Gangwon-Do province. The results show that the firms have product safety regulations, but the number of firms which its employees understand the regulations is less than the number of firms which do not understand. Also the number of firms which is preparing PL prevention and insurance, and counterplan for accidents seems to be not in large numbers.

The product information is defined as the information that is obtained in the whole life cycle of a product from design and manufacturing to marketing and it carries out the important role under the changeful environment. It is necessary to use computers for efficient product data sharing. But, in practice, because of various product data types and heterogeneous computing environment, it is difficult to share the product information among different computer systems. This paper presents the methodology for sharing the product information without a hitch in he-terogeneous computing environment by using the international standard of the product information ISO-10303 STEP and CORBA.

The purpose of this study is to investigate the influence of four influencing variables (brand diversity. product information, entertainment, and trust) on purchase Intention and to .examine whether this relationship varies according to the buyer's perceived level of Product involvement. Analysis of 264 responses using the hierarchical regression indicated that all four independent variables were found positively influencing purchase intention. Furthermore, the effects of brand diversity, product information, and trust on purchase intention were revealed to be moderated by perceived product involvement. However, the moderating effect of product involvement on the relationship between entertainment and purchase intention was not statistically significant. Discussions for research findings and managerial implications are discussed.

In this paper, module of a product is determined by the characteristics of a product itself and art assembly process. To analyze the characteristics o( the product, assembly function, structure of subassembly and parts could be considered. Based on the analysis of characteristics of product structure, assembly process and product function, determination criteria of a module could be proposed. For the assembly process, assembly methods, assembly equipment and workers could be considered. For the product structure, constituent object and structural feature could also be considered. To obtain the interrelationship between the product and the assembly process, the matrix table could be used to find the influencing factors that affected the module.

This paper presents an integral model for product safety and product liability resulting from a defective product. The essence of the paper is the process of supply of manufacturing products which satisfy the product liability and the product safety in terms of consumers expectation levels. The main criteria of the product safety is the hazard level which involves in the severity and frequency. The proposed model shows the process to supply the manufactured products under the conditions that they are suitable in comparison of hazard level and safety level established by each company. If the product do not meet the safety level, this paper proposes that four different types of PL and PS countermeasures for the risk types are forward, respectively.

This study proposed a method to apply risk management standards to a product safety management program and reviewed cases where a risk management cycle is applied to the product safety management program. Comparing the four product safety management programs suggested by several authors yielded common features of the risk management cycle: (1) organization for product safety, (2) risk identification, (3) risk evaluation, (4) risk treatment, (5) monitoring/communication, and (6) documentation. A Japan company(Ricoh)'s case showed that the risk management cycle to treat product liability risks can be used as a successful product safety management program.

최근 복지 수요 확대에 따라 민간 영역의 복지자원에 대한 관심이 높아짐에도 불구하고 자원의 형태에 따른 관심은 주로 현금자원에 집중되어 현물자원에 대한 논의는 미흡한 실정이다. 이에 본 연구는 효과적인 현물중개를 위해 현물기부 경험이 있는 기업 및 모금기관을 대상으로 현물기부 중개 경험과 현물기부제도 및 활성화방안에 대한 인식을 심층적으로 탐색하고자 하였다. 조사대상은 현물기부 경험이 있는 주요 비영리기관 2곳과 기업 4곳의 실무자를 대상으로 심층면접을 통한 사례연구방법을 적용하였다. 분석결과, 효과적인 현물기부 활성화를 위해서는 온라인 등 새로운 방식을 활용한 현물기부 전문중개시스템 구축과 전문화된 중개서비스 및 프로그램 개발, 기업, 비영리기관, 정부간 파트너쉽 구축이 현물기부 운영적 측면에서 개선되어야 하고, 더불어 현물기부 세제지원과 물품단가의 합리적 산정과 같은 제도적 지원이 강화되어야 할 것이다.

The purpose of this research is to investigate the effects of the product display type on the consumers' purchase intention, attitude toward store, and revisit intention in the various mobile shopping situations. To test the hypothesis, between-subjects experiment with 3 mobile shopping situations (outdoor place, public transportation, commercial facilities) by 3 product display types (search, category, product) was conducted, and analyzed with ANCOVA (analysis of covariance). The result of the experiment shows there are no main effects of the mobile shopping situations and the product display types, but the interaction effects of the product display type and the mobile shopping situation on the purchase intention and the revisit intention are statistically significant. However the attitude toward the store is not affected by the treatments. Experiment results suggest that the positive consumer responses in terms of the purchase and revisit intention can be achieved when the product display is matched with the situation in the mobile shopping setting. Controlling consumers' evaluation on the product information and their experience of online shopping, we can take these effect as the results of match-up between the product display type and the situational factors surrounding mobile shopping. The result provides strong support for the location-based service in mobile shopping. Most of the mobile device can utilize the consumers' location which can be easily interpreted as the situational factors. With regard of the level of the external stimulation, the shopping service providers can offer the main interface with the right match with the consumers' situations. When the external stimulation level is high, they should provide the category display or product display in the target promotion in their mobile shopping apps. However if the target is on the way with the low external stimulation level, they should provide the search format as the main interface in their apps. More interestingly, this kind of manipulation does not affect the consumers' attitude toward the store according to our research result. Future research direction is discussed.
