Due to the awareness for the importance of social capital, many researches have investigated that social capital contributes to the successful implementation of product innovation. Although most researchers tried to model the effect of social capital on product innovation as a linear relation, we consider it too simplistic and fuzzy because knowledge utilization which ultimately leads to product innovation should exist in the relationship between social capital and product innovation. Using 107 survey data, this study found there is a partial mediating effect of knowledge utilization on the link between structure aspect of social capital and product innovation (i.e., new product development and improvement in existing products). Next, this study reported knowledge utilization does act as a perfect mediating variable on the link between awareness aspect of social capital and improvement of existing products, but act as a partial mediating variable on the link between awareness aspect of social capital and new product development. Finally, this study found that knowledge utilization does not act as a mediating variable on the link between relation aspect of social capita and product innovation.

We have developed new type of LCD Device which enables switching from reflective to tranmissive LCD mode and vice versa according to brightness of the surrounding. Alternation in these modes are possible by adding on circular polarized sheet and retardation film onto the bottom polarizer which allows the control of the back light and the LCD cell gamma voltage depending on the atmosphere. This method has been evaluated and confirmed by running on the LCD module device in which we have optimized retardation value by Poincare polarizer analysis.

In this study, factors affecting the development of new products and research about the relevance of the factors based on the research model was configured. Existing research and technology commercialization process of discrimination that occur in the importance of risk management and open innovation company's competitive advantage in new product development and affect the reporter know what the effect is used as a control variable effects. Factor in the development of new products through research and innovation capacity and knowledge management activities, the introduction of open innovation and enterprise level ever due to the level of risk management controls and the need for effective research to study the model was proposed.

Purpose : Recently, many quality issues are aroused in military forces, such as failures in K-series weapons, combat uniforms' defects and 40mm ammunition explosion accident. To address these problems, Defense Agency for Technology and Quality(DTaQ) introduced new systems such as Manufacturing Readiness Assessment(MRA), Test Report Information System(TRIS) and so on. However, these activities require the human and time resources which cannot be increased in short period. In this paper, we suggest more practical and efficient product examination method. Methods : The most popular and widely used government's quality assurance technique is a sampling method to examine the product. In this research, we first reviewed the DTaQ's quality assurance regulation, then identified several possible problems and finally suggested more efficient and effective sampling plans. Results : We have suggested new sampling framework and evaluated its performance on two military supplies by comparing with other sampling method, and observed that the number of tested samples can be substantially reduced. Therefore, required quality assurance time can be saved. Conclusion : In this paper, we first reviewed the product examination frameworks of DTaQ, PPQMS and DCMA. Then we identified several possible problems which can cause the loss of objectivity and time. To handle these problems, we suggested the new product examination framework and tested the framework to verify the performance.

오늘날 비즈니스 환경에서 기업이 직면한 가장 심각한 문제는 신제품개발성과에 실패하는 것이다. 통계적으로 매년 출시된 신제품의 거의 과반수이상이 시장에서 성공하지 못한 것으로 나타났다. 기술진보가 혁신적으로 일어남에도 불구하고 소비자의 기대수준은 더욱 높아지고 국내외 경쟁이 치열해짐에 따라 신제품 수명주기는 갈수록 짧아지고 있다. 시장에서 장기간 성공할 수 있는 상품을 개발하지 않고는 기업은 살아남기가 어렵다. 결국 기업의 성공과 실패에서 가장 중요한 문제는 신제품의 성공적인 도입과 개발일 수밖에 없다. 기존 연구에서 신제품개발성과를 달성하기 위해 다양한 요인을 제시하고 있지만 본 연구에서는 동적역량을 주요 요인으로 보고 구성요인을 파악하고자 한다. 기업이 지속적으로 생존하고 발전하기 위해서 자원을 획득, 흡수, 통합 및 재구성할 수 있는 역량이 필요하며 변화하는 환경에 적응하기 위해서 신속하게 자원기반을 전환할 수 있는 동적능력이 결정적이기 때문이다. 156개의 중국 중소제조기업을 대상으로 실증분석을 한 결과 학습역량, 재구성역량, 동맹역량이 신제품개발성과에 긍정적인 영향을 미치는 것으로 나타났고, 환경동태성이 높을수록 통합역량과 재구성역량이 신제품개발성과에 강하게 영향을 미치는 것으로 나타났다.

In this article, a new operation on product fuzzy graphs (PFGs) is provide; namely β-product. We give sufficient conditions for the β-product of two PFGs to be strong and we prove if the β-product of two PFGs is complete, then one of them is strong. We also study the unbiased notion of the class of PFGs and necessary and sufficient conditions for the β-product to be unbiased are given.

This study reviewed the national standards for risk management to judge whether they are suitable for a product safety management program. Among the standards issued from Australia, New Zealand, Canada, Japan, and UK, the risk management guideline (AS/NZS 4360: 2000) issued jointly from both Australia and New Zealand have better features of product safety management program such as a broad definition of risk concept including opportunities of loss and gain, stepwise composition of processes applicable iteratively, and integrable composition of processes for the existing other management practice. Comparing the three product safety management programs suggested by several authors yielded common features of product safety management program model: (1) organization for product safety, (2) risk identification, (3) risk evaluation, (4) risk treatment, (5) monitoring/communication, and (6) documentation. All of these activities can be performed within risk management framework.

In this paper, an improved lower bound on the burst-error correcting capability of th ecyclic product code is presented and through the analysis of this new bound clustered cyclic product (CCP abbr.)code is proposed. The CCP code, to improve the burst-error correcting capability, combines the idea of clustering and the transmission method of cyclic product code. That is, a cluster which is defined in this paper as a group of consecutive code symbols is employed as a new transmission unit to the code array transmission of cyclic product code. the burst-error correcting capability of the CCP code is improved without a loss in the random-error correcting capability and performance comparison in the digital video camera records (DVCR) system shows the superiority of the proposed CCP code over conventional product codes.

With science and technology getting more and more advanced, the scope of digital product is expanding and the new products continuously are introduced on the market. On the basis of consumers' attachment to products, we investigated the consumers' behaviors towards the product when a digital product is extended. As a result of an empirical analysis, it turned out that a consumer tended to have higher trust and a positive emotion about relevant goods if he or she had a strong attachment to digital products. However, even though one had a strong attachment to digital products, the emotion about the corresponding brands did not necessarily appeared to be positive. In the event that a brand of digital products was extended to other new products, only the trust in the brand exerted significant influence on the consumers' behaviors towards the extended products. Finally, this study suggests some theoretical and managerial implications for effective strategies in response to customers' attachment to digital product.

Using data on the U.S. automobile industry between 1979 and 1999, we have investigated the impact of inter-divisional domain overlap on a division's product differentiation vis-$\grave{a}$-vis sister divisions. The results show that the higher the level of inter-divisional domain overlap, relative to the focal division's own domain, the higher the chances of locating a new product closer to the existing products of a sister division, thereby decreasing product differentiation vis-$\grave{a}$-vis this sister division. We argue that this is due to a high level of similar capabilities between the two divisions and the division with less distinctive capabilities may have little choice but to launch a new product that is close to the products of the other division.
