The objective of the study is to review trends of clothing export in important countries of the world and thus to know the present stage of clothing export in Korea. For the purpose, changes of export amount, competitiveness and product life cycle were analysed in the countries from the 1960's to the 1990's. The results are as following: First, on the aspect of export amount, industrialized countries lost the lead to newly industrializing countries from the 1960's. Developing countries, as China, win the lead. Second, on the competitiveness aspect, industrialized countries lost competitiveness to newly industrializing countries before the 1960's. And newly industrializing countries were outpaced by China in the export competitiveness from the early 1990's. Third, on the aspect of product life cycle, industrialized countries go first through each period of product life cycle, introduction, growth, maturity and decline, and they all, excluding Japan, sustained period of Maturity for a long time. newly industrializing countries and developing countries go orderly through each period of product life cycle after industrialized countries. As to Korea, duration of each period was short. Specially characteristics of decline period appeared partly in the early 1990's. From the results, the theory of product life cycle, helping to explain changes in production and trade in new product lines, estimated to applicable to clothing export. The phenomena, Italy, Hong Kong and America sustain high competitiveness in the world clothing market for a long time, is needed to be studied carefully. The study about strong points in their clothing industries and competitiveness drive program be to influence Korean export policy in the future.

Life cycle assessment(LCA) has been developed from the concept of life cycle thinking. Life cycle thinking implies that everyone in the whole chain of a product's life cycle, from cradle to grave, has a responsibility and a role to play, taking into account all the relevant external effects. LCA is an analytical tool for identifying environmental loads and assessing the environmental impact in the whole chain of a product's life cycle. In Europe and Japan, LCA and ecodesign study for railway industry have been actively carried out recently. However, LCA for railway industry in domestic is still infant. LCA is standardized in International Organization of Standardization(ISO), base on the ISO 14040 standards, 307 life cycle inventory(LCI) database for infrastructure and base materials have been established in total since 1999. Some of LCI database can use in performing LCA for trains and railway infrastructure, but still not enough to derive accurate LCA result. Therefore, railway oriented LCA methodology and LCI DB are needed to be developed.

The importance of usability evaluation is increasing in developing the system(or product). Many usability measures and test methods have been developed in the fields of ergonomics and cognitive engineering. A systematic usability effort using established methods may be qualify as usability engineering. In this paper, general aspects of the usability engineering are introduced, and application methods of usability engineering model based on product's life cycle are presented.

A recent Tilting train development operation for existing line high speed, already developed "Korean Tilting Train eXpress(bellow TTX)" and that doing demonstration of operation. And TTX are going to commercial service in 2012. They are preparing Environmental Declaration of Product(bellow EDP) for offering environmental impact of TTX to customer. EDP calculated environmental impact of target product's whole life cycle(raw material and manufacturing, distribution, use, end of life) more quantity for that improving environmental impact and then certification them, it is using for that estimate some part of existence of specific pollutants, GHGs, energy consumption and recycling ratio. In this study, 1) analyze the process of getting EDP, 2) satisfy common criteria and each criteria(plan) in the Product Category Rules(bellow PCRs) provided KEITI, 3) according to ISO 14044, implementation of LCA. 4) These results be shown Characterized Impact(bellow CI) about each life cycle stage and six impact categories(ARD, GWP, OD, AD, EU, POC).

미국은 2000년대 초반부터 무기체계의 전투준비태세를 유지하면서 수명주기비용을 줄이기 위해서 TLCSM를 적용하였다. TLCSM이 적용되면서 획득단계 중심의 ILS 개념에서 전체 수명주기 동안 수명주기비용을 관리하는 개념인 IPS로 전환하였다. 또한 ILS를 개발하기 위한 LSAR은 IPS을 개발하기 위한 LPD로 전환하였다. 본 연구에서는 한국의 LSAR과 미국의 LPD를 비교 및 분석하여 LPD의 한국 도입 시 필요한 정책을 제안하였다.

제품수명주기관리(Product Lifecycle Management)는 8개의 지식영역으로 구성된 잘 정의된 관리방법이다. 4차 산업혁명이 스마트 팩토리와 밀접한 관련이 있기 때문에 궁극적으로 제품의 아이디어 생성에서 폐기까지의 전 과정을 효과적으로 관리하는 제품수명주기관리의 중요성이 부각되고 있다. 본 연구는 제품수명주기관리 분야의 전문가를 대상으로 제품수명주기관리의 지식영역의 현재와 향후 적용정도를 4차 산업혁명의 관점에서 분석하였다. 제품수명주기관리의 지식영역이 현장에서 어느 정도 적용되고 있는지를 현재의 관점과 가까운 미래의 관점에서 전문가 인식을 분석하였다. 제품수명주기관리의 지식영역의 현재 및 미래의 적용정도를 분석하고, 적용정도의 관점에서 지식영역 간의 차이가 있는지를 분석하였다. 분석된 결과를 중심으로 그 의미와 향후 흐름을 제시하였다.

일반적으로 제품에 제품수명주기(product life cycle)가 있듯이 브랜드에도 브랜드수명주기(brand life cycle)가 있다. 도입기, 성장기, 성숙기, 쇠퇴기로 구분되는 이 수명주기는 제품에 적용될 때와는 다르게 브랜드에 적용될 때 약간의 차이가 발생하는데 그것은 브랜드의 수명주기가 제품의 수명주기와는 약간은 다른 Cycle를 가지고 있기 때문이다.. 브랜드를 소비자들에게 인지시키는 가장 효과적인 방법은 광고이며 따라서 광고디자인에 있어서도 그 브랜드의 수명주기상의 현재 위치를 파악하고 거기에 맞는 전략을 사용하는 것이 매우 중요하다 할 수 있다. 본 논문에서는 브랜드수명주기의 개념을 정리하고 각 단계별 광고디자인 전략을 제안하였다. 브랜드의 도입 기에는 그 브랜드 자체가 무엇인지를 알릴 수 있는 'What is it? strategy'가 사용되어져야 하고 성장기에는 많은 경쟁브랜드들이 존재하는 시기이기 때문에 경쟁 브랜드들 사이에서 차별적 우위를 드러낼 수 있는 포지셔닝을 강조하는 광고전략으로 'How does it differ from? strategy'를 제안하였으며 성숙기에는 그 브랜드를 사용함으로써 소비자들이 얻을 수 있는 가치의 전달에 중점을 두는 'What does it convey of? strategy' 쇠퇴기에는 브랜드 자체의 속성이나 효익을 강조하기보다는 그 브랜드가 가질 수 있는 상징적 의미의 창출에 중점을 두는 'What does it stand for? strategy'를 제안하였다. 이렇듯 광고디자인에도 브렌드 수명주기에 따른 적절한 전략의 변화가 요구되어지며 이를 통해 효과적인 브랜드관리가 이루어져야 할 것이다.

Concurrent Engineering (CE) has presented new possibilities for successful product development by incorporating various product life-cycle functions from the earlier stage of design. In the product design, geometric representation is vital not only in its traditional role as a means of communicating design information but also in its role as a means of externalizing designer's thought process by visualizing the design product. During the last dozens of years, there has been extraordinary development of computer-aided tools intended to generate, present or communicate 3D models. However, there has not been comparable progress in the development of 3D-CAD systems intended to represent and manipulate a variety of product life-cycle information in a consistent manner. In the previous research, the authors proposed a novel concept called Minus Volume (MV) to incorporate various design information relevant to product life-cycle functions. This paper proposes the use of the MV concept for the collaborative design environment, where many team members are geographically distributed over the networked environment, including Internet, Intranet, WWW, etc. A prototype 3D-CAD system is implemented based on the MV concept and illustrated with the successful implementation of collaborative design example.

This paper proposes a novel concept, Minus Volume (MV), to incorporate various design information relevant to product lift-cycle functions. MV is a functional shape that is extracted from a design object within a bounding box. A prototype 3D-CAD system is implemented based on the MV concept and illustrated with the successful implementation of concurrent design and manufacturing.

According to the ISO 14040(1997), Life Cycle Assessment is not the tool only focusing on the emissions from the manufacturing processes of a product, but the tool also expressing environmental adverse impact quantitatively through products entire life cycle (i.e. raw material acquisition, manufacturing, transportation, use, and end-of-life stage). Because the LCA for EMUs(Electrical Multiple Units), however, requires astronomical time and cost for collecting big amount of data. it is inevitable to bring in the simplified LCA methodology, In this study, we introduced standardized methodology of LCA in the world, and found appropriate S-LCA methodology for EMUs. Furthermore, we recommended how to evaluate the environmental impact of EMUs in detail and precisely, using the S-LCA.
