  • The purpose of the study is to establish sustainability evaluation items that can be applied to enhance clothing sustainability practice. The sustainability evaluation items related to clothing by product category, use, and disposal were derived through literature review. In order to evaluate the validity of the derived evaluation items, preliminary survey and two questionnaires were conducted for experts, and the importance and the possibility of change were measured. As a result, 39 evaluation items were constructed. Among the 39 evaluation items, 26 items related to the use and disposal were evaluated for 10 weeks in the 20s and 30s female consumers in terms of practice. The results of the study are as follows: First, items that have a high degree of importance and possibility of change are the items that can minimize resource saving, recycling, and the emission of harmful substances. Second, the participants' perceptions, attitudes, and outcomes of practicing the evaluation items of the use and disposal phase were proved to be positively affected, and the possibility of reducing resource saving and environmental impacts was proved. The clothing sustainability practice played a positive and developmental role in real life, while changing from small things to pursuing newness. The vagueness of sustainability was changed to specific perceptions and behaviors through the practice of the evaluation items.

  • Concurrent Engineering (CE) is a popular method employed in product development. It treats the whole product design process by the consideration of product quality, cost, rate of progress, and demands of customers. The development of computer and network technologies provides a strong support to the realization of CE in practice. Aiming at the characteristics of CE and network collaborative design, this paper built network collaborative design system frame. Through the analysis of the network collaborative design modes based on CE, this paper provided a novel network collaborative design integration model. This model can integrate the product design information, design process, and knowledge. Intelligent collaboration was considered in the proposed model. The study showed that the proposed model considered main factors such as information, knowledge, and design process in collaborative design. It has potential application in CE fields.

  • The environment surrounded by industries is represented by the 3Cs : Customers, Competition, and Changes. The 3Cs drive industries to pursue external business targets such as customer's needs and marketplaces with BPR (Business Process Reengineering). BPR addresses core business process. One of these core business processes is product development. This product development process has been reengineered by the concept of CE (Concurrent Engineering). The aim of the paper is to build frameworks of CE to clarify the CE concept. This paper begins with investigating the product development process from the perspectives of three drivers: cost, quality and speed. CE frameworks are then followed. The first frmework is concerned with the CE definition and thus three keyphrases are extracted : from the outset, concurrent design and systematic approach. Concerned with the CE implementation, the second framework is composed of five components: generalist & specialist, cross-function team, enabling tools & techniques, success metrics, and total visibility. This paper concludes that the CE practice is hard to achieve because of the 'dont't-tell-them-early' attitude of upstream people, and the 'wait-and-see' attitude of downstream people. As resolution, a change management program is recommended that changes an employees mind-set. This paper also supposes computer systems which facilitate and keep automatic track of the CE process as engineered. Finally it gives a warning that computer systems alone do not guarantee success without being preceded by process re-engineering.

  • As environmental issues have become a worldwide concern after the 20th century, the idea and the term of 'green growth development' has become familiar to the public. After 2008, the green growth development dramatically became an important ideology in Korea; thus industries, studies and product investments in relation are in active progress. Following the trend, the latter major unit of the middle school textbook "Technology & Home Economics" was named the revision of elementary, middle and high school textbooks in 2009. The learning goal of 'green' or 'eco-friendly' of the revised edition of the textbook will guide the middle school students to have better understanding of the issues of clothing habits and the environment. Furthermore, students will be able to apply the 'green' concepts in their real life and put eco-friendly clothing habits into action. Thus, the practice of effective learning will depend on the quality of the current issue of the textbook. Therefore this study analyzes the eco-friendly contents of the semi-unit from 7 different textbooks and presents an example of textbook production to the preliminary teacher of home economics.

  • 고객의 요구나 선호도가 다양해짐에 따라 제품의 다양화가 필요하지만, 이는 오퍼레이션스의 비효율성이 야기될 수 있어 기업의 중요 관심사가 되고 있다. 따라서 원활한 오퍼레이션스 기능 수행을 위해 기업들은 제품의 모듈화 구조를 도입해 왔다. 하지만 신제품 개발 과정에서 모듈화의 효과를 계량적으로 분석한 연구는 미흡하다. 이에 본 연구는 기존 제품에 신기술이 포함된 부품이 도입되는 제품개발의 상황에서 모듈화가 기업의 수익에 미치는 영향에 관한 계량모델을 개발하고 이를 분석하여 몇 가지 중요한 명제를 도출함으로써 신제품 개발 시 고려해야 할 신기술 도입 및 모듈화의 의사결정에 필요한 가이드라인을 제시하였다. 연구 결과, i) 제품의 업그레이드가 용이하거나, ii) 외부요인으로 인해 제품의 가격이 높게 책정되어야 할 경우, iii) 신기술 투자비용의 효과가 불확실할 경우, 모듈화 수준을 높이는 노력이 필요하고, 모듈화에 대한 수요탄력성이 낮은 제품의 신제품 개발 시에는 신기술 도입의 투자비용을 늘리는 것이 바람직하다.

  • Most of the automotive electronic systems are equipped with control software. ISO 26262 standard has been published to prevent unreasonable risk due to E/E system malfunction. And many automotive companies apply ISO 26262 for safe series product. In ISO 26262 standard, the product quality improves through deductive and inductive safety analysis in all processes including system and software development phase. However, there are few studies on software safety analysis than systems. In the paper, we study the software FMEA(Failure Mode Effect Analysis) technique for product quality of vehicular embedded software. And we propose an effective guideline of software FMEA as EPB industrial practice.

  • Over the past 20 years, constant progress in noise and vibration (NVH) engineering has enabled to constantly advance quality and comfort of operation and use of really any products - from automobiles to aircraft, to all kinds of industrial vehicles and machines - to the extend that for many products, supreme NVH performance has becomes part of its brand image in the market. At the same time, the product innovation agenda in the automotive, aircraft and really many other industries, has been extended very much in recent years by meeting ever more strict environmental regulations. Like in the automotive industry, the drive towards meeting emission and CO2 targets leads to very much accelerated adoption of new powertrain concepts (downsizing of ICE, hybrid-electrical...), and to new vehicle architectures and the application of new materials to reduce weight, which bring new challenges for not only maintaining but further improving NVH performance. This drives for innovation in NVH engineering, so as to succeed in meeting a product brand performance for NVH, while as the same time satisfying eco-constraints. Product innovation has also become increasingly dependent on the adoption of electronics and software, which drives for new solutions for NVH engineering that can be applied for NVH performance optimization of mechatronic products. Finally, relentless pressure to shorten time to market while maintaining overall product quality and reliability, mandates that the practice and solutions for NVH engineering can be optimally applied in all phases of product development. The presentation will first review the afore trends for product and process innovation, and discuss the challenges they represent for NVH engineering. Next, the presentation discusses new solutions for NVH engineering of products, so as to meet target brand values, while at the same time meeting ever more strict eco constraints, and this within a context of increasing adoption of electronics and controls to drive product innovation. NVH being very much defined by system level performance, these solutions implement the approach of "Model Based System Engineering" to increase the impact of system level analysis for NVH in all phases of product development: - At the Concept Phase, to be able to do business case analysis of new product concepts; to arrive at an optimized and robust product architecture (e.g. to hybrid powertrain lay-out, to optimize fuel economy); to enable target cascading, to subsystem and component level. - In Development Phase, to increase realism and productivity of simulation, so as to frontload virtual validation of components and subsystems and to further reduce reliance on physical testing. - During the final System Testing Phase, to enable subsystem testing by a combination of physical testing and simulation: using simulation models to simulate the final integration context when testing a subsystem, enabling to frontload subsystem testing before final system integration is possible. - To interconnect Mechanical, Electronical and Controls engineering, in all phases of development, by supporting model driven controls engineering (MIL, SIL, HIL). Finally, the presentation reviews examples of how LMS is implementing such new applications for NVH engineering with lead customers in Europe, Asia and US, with demonstrated benefits both in terms of shortening development cycles, and/or enabling a simulation based approach to reduce reliance on physical testing.

  • With the rapid development of nowadays technologies, the environment of product development is experiencing structural changes than ever. Manufacturers are put under never-experienced pressures to launch their products in the market both faster and less expensively than their competitors while continuously improving product quality These pressures have given birth to so-called, Concurrent Engineering which is a systematic approach to the integrated, concurrent design of products and their related processes, including manufacture and support. Most manufactiring companies now recognize the importance of concurrent engineering and put heavy emphasis on the research and impementation of concurrent engineering. However, with this fundamental change in the process of product development, designers rarely pay attention to this newly demanding process. Designers still stay in the middle of process, satisfying their roles in dealing with aesthetic points of product. Designers badly need to incorporate the concept of concurrent engineering to design to design process and to adapt to this new environment. With these backgrounds, the study sets the objective to understand the nature of concurrent engineering and explore the possibility of it's application to industrial design. Particularly this study focuses on how the concept of concurrent engineering can be applied from the stage of form development to prototyping. At first, background, objectives, and scope of the study are discussed as an introductory part. It is followed by reviewing theories of concurrent engineering such as definition, history, technologies, examples, state of art and so on. Subsequently industrial design is viewed in terms of concurrent engineering and problems in industrial design are identified. Base on the findinss of precedent part of study, new process of industrial design incorporating concurrent engineering is developed. For the demonstration of new process, a case study of design of palm-top printer is introduced. Case study shows how the sketch, and forms can be transformed into prototyping with the simultaneous cooperation with engineering and other related specialists. Finally the study in summarized and future studies are prospected.

  • 컴퓨터를 활용한 커뮤니케이션 기술의 발전은 디자인 환경에서 컴퓨터 그래픽스(Computer Graphics - 이하는 CG로 명명함)의 활용을 일반화하고 디자인의 표현 한계를 확대하게 되었다. 따라서 다양한 디자인 영역에 적합하게 적용할 수 있는 CG 활용의 기술과 방법은 디자인의 결과와 밀접한 관계가 있으며, 디자이너와 디자인 환경에 대한 경쟁력 의 요건이 되고 있다. 특히 학생들의 전문성을 책임져야 하는 대학의 교과과정에서 CG 응용에 관한 내용은 경쟁력 있는 교육적 성과가 더욱 요구되는 것이다. 이러한 의미에서 본 연구는 공업(제품)디자인 학과에 개설된 “컴퓨터 응용 디자인”이란 교과목의 내용을 중심으로 CG 활용 교육에 대한 방법론적인 접근을 한 것이다. 연구의 내용은 제품디자인의 표현내용을 중심으로 편성한 10개의 실습 과정에 대한 개념과 방법, 그리고 이를 실천한 학생들의 결과들을 사례로서 제시하였다. 이 과정에서 학생들이 제품 디자인과 CG 분야의 이해, 그리고 CG 프로그램의 구체적인 기능과 활용의 방법을 배우게 된 것을 성과라고 할 수 있다.
