In Korean Electric Motor Unit(EMU) industry, the government should lead and drive the development of the product-oriented fundamental technologies(for example, Life Cycle Assessment, Environmental Labelling, Ecodesign, Eco-efficiency etc.) for the EMU. International Railway Union(UIC) establish UIC code 345: Environmental specification and it is based on using the product-oriented fundamental technologies. And also many foreign railway related companies already shown their environmental performance using the product-oriented fundamental technologies So, in Korean situation, it is important that let the EMU industrial player understand the importance of the product-oriented fundamental technology for the EMU and clarify who drive the development of the product-oriented fundamental technology for the EMU and what the type of driving forces.

One of the recent hot issues in the manufacturing business is how to incorporate environmental attributes into product and process design. Design for environment considers the potential environmental impact of a product throughout its life-cycle. In the case of something breaks, it can become waste immediately, hence reliability and durability is the essential part of product design. This paper presents reliability technology for sustainable product design to improve the product longevity that extends performance life, serviceability and durability. The presented method will help to develop a sound design and avoid weak links to minimize the waste.

In this paper, the difficulties involved in analyzing and designing a management system for product development are discussed with reference to reducing the impact of products on the environment. We propose some models and methods to analyze information behavior in the process of product development based on a fusion model which integrates the assessments of users’ needs, the environment, and available technology. These models and methods are subsequently applied to the development of a new packaging material. The results of this case study allow us to identify effective information for the design of a management system for product development to reduce the impact of products on the environment.

This paper proposes a multi-level product modeling framework for long-term lifecycle products. The framework can help engineers to define product models and relate them to physical instances. The framework is defined in three levels; data, design model, modeling language. The data level represents real-world products, The model level describes design models of real-world products. The modeling language level defines concepts and relationships to describe product design models. The concepts and relationships in the modeling language level enable engineers to express the semantics of product models in an engineering-friendly way. The interactions between these three levels are explained to show how the framework can manage long-term lifecycle product information. A prototype system is provided for further understanding of the framework.

본 연구는 UTAUT이론을 바탕으로 정보통신 기술수용연구에서 상대적으로 간과되어왔던 다양한 제품특성(제품기능성, 디자인, 사용편의성)이 기능적 동기(노력기대, 성과기대)와 쾌락적 동기(인지된 즐거움)에 미치는 영향과 사용동기가 스마트 디바이스 사용의도에 어떠한 영향을 미치는지 규명하고자 진행되었다. 서울을 포함하여 5대광역시의 스마트 디바이스 사용자 800명을 비례할당방식으로 조사한 결과, 기능적 동기(노력기대, 성과기대)와 쾌락적 동기(인지된 즐거움)는 스마트 디바이스 사용의도에 정(+)의 영향을 미치는 것으로 나타났으며, 스마트 디바이스의 디자인은 인지된 즐거움에, 사용용이성은 노력기대와 성과기대에 각각 정(+)의 영향을 미치는 것으로 나타났다. 그러나 제품기능성은 노력기대와 성과기대에 유의한 영향을 미치지 못하는 것으로 나타났다.

The leaf extracts of Araucaria bidwillii Hook. (Araucariaceae) were evaluated for their cytotoxic effect in various human cancer cell lines. Preliminary investigation by brine shrimp lethality assay indicated that $LC_{50}$ value of various successive extracts were found to be less than $1000\;{\mu}g/ml$, where the ethyl acetate extract showed maximum activity of less than $100\;{\mu}g/ml$. Further cytotoxic evaluation of various leaf extracts of Araucaria bidwilli Hook was carried out in four different human cancer cell lines-acute myeloblastic leukemia (HL-60), chronic myelogenic leukemia (K-562), breast adenocarcinoma (MCF-7) and cervical epithelial carcinoma (HeLa). Cytotoxicity was assessed by trypan blue dye exclusion method and 3-(4,5-dimethyl thiazole-2yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay. From the present investigation it was found that the ethyl acetate and methanol extract of Araucaria bidwilli Hook was found to be more effective in leukemic cell lines and was less effective in MCF-7 and HeLa. The $IC_{50}$ value of the ethyl acetate extract in leukemic cell lines was found to be $28.18\;and\;34.64\;{\mu}g/ml$ and methanol extract was found to be $33.11\;&\;39.81\;{\mu}g/ml$. It can be concluded that various extract from the leaves of Araucaria bidwillii Hook. posses cytotoxic activity tested in brine shrimps and various human carcinoma cell lines.

본 연구에서는 기업의 외부 혁신 원천의 하나인 공급사와의 기술협력을 중심으로 기술협력의 선행요인들을 식별하고, 이들 선행요인들이 신제품 개발 성과에 실질적인 영향을 미치는지를 살펴보고자 한다. 분석을 위하여 2012년 산업통상부와 생산성본부가 함께 수행한 600개 제조업을 대상으로 한 MPS 패널 데이터를 사용하였다. 기술협력의 선행요인으로 신뢰, 통제 및 정보공유를 사용하였고 이들이 공급사와 구매사의 기술협력 성과에 미치는 영향을 회귀분석 하였다. 또한 신뢰, 통제 및 정보공유가 기술협력을 매개로 하여 신제품 성과에 영향을 주고 있는지에 관한 매개분석을 실시하였다. 분석결과 두 기업 간 신뢰, 통제 그리고 정보공유는 공급사-구매사의 기술협력 성과에 긍정적으로 작용하고 있으며 기술협력의 수준이 높을수록 신제품성과가 향상되는 것으로 나타났다. 선행요인 중 신뢰는 기술협력을 매개로하여 신제품 성과에도 긍정적으로 작용하는 것으로 나타났다. 본 결과는 기업이 다양한 외부 조직과의 혁신활동 수행에 있어 참여조직 간의 사회적 자산인 신뢰의 형성 및 관리가 개방형혁신 성공에 중요한 역할을 하고 있음을 시사한다.

The purpose of this paper is to analyze the organizational design and management of product development in creating new product architecture by an established firm. For the purpose, the paper put up the organizational design in the process of PDA(Personal Digital Assistant) development of Sharp and Casio which were Japanese major PDA firms in 1990s. PDA is the product born through architectural change from Electronic Organizer. Prior research on the product architecture change and organizational adaptation emphasized that an established firm is difficult to adapt to new product architecture due to the restriction of prior technology or organizational inertia. For overcoming these problems and successful development of new product architecture, organizational design and management in the process of product development becomes essential. In case of Sharp, corporate development project team had been used to overcome the restrictions from architectural knowledge accumulated through previous product. After launching first new PDA by corporate development project team, Sharp created a new division and pushed an evolution of PDA, when new PDA market start to grow up rapidly toward a major market segmentation. As a result, Sharp was able to build up stable PDA project trajectory. However, Casio was late for three years in launching of new PDA architecture because previous division charging of Electronic Organizer tried to develop first new PDA. Casio's PDA development was prohibited by engineers of previous division because new PDA architecture was inferior on user interface and display definition. That is, Casio's first PDA development was restricted by architectural knowledge of previous product.
