오늘날의 제품은 양적 질적인 면에서 기하급수적으로 향상되어있는 상태이고, 따라서 제품시장도 과거에 비해, 다변화 세분화되어있다. 이러한 현실 속에서 소비자의 니즈를 반영한 제품이란 단지 기능적인 측면만이 아닌, 감성적 또는 기호적으로 다양한 소비자의 욕구를 만족시키는 제품을 의미하는 것이다. (중략)

본 연구는 디자인 3대 요소인 '심미성', '재료', '기능성/구조성'의 요소에 '제거', '감소', '증가', '창조'라는 4가지 디자인 사고 틀 적용을 통하여, 새로운 제품디자인 컨셉 및 아이디어개발을 위한 사고방법을 제안하였다. 본 연구에서 제안 된 혁신제품 아이디어 창출 방법의 검증을 위해서 성공적인 혁신 제품 디자인 사례로 소개된 232개의 제품들을 분석하였다. 그 연구결과의 대표적 결론은 다음과 같다. 첫째, 본 연구에서 개발한 '대표적인 디자인 가치요소인인 '심미성', '재료', '기능성/구조성'의 요소를 기준으로 한 4가지 디자인사고 프레임?'은 혁신제품 디자인 개발을 위한 시스템적인 창의력 사고 방법에 도움을 줄 수 있을 것이다. 둘째, 혁신제품 디자인 사례 분석 결과 41%의 혁신제품디자인은 디자인 요소 중 '기능성/구조성'의 혁신을 통하여 이루어졌다. 셋째, 기존의 혁신제품디자인(74%)은 디자인요소에 대한 가치의 '제거와 감소' 보다는 디자인요소에 대한 가치의 '증가와 창조'를 통하여 이루었다. 본 연구에서 제안한 연구 결과는 디자이너들이 가장 힘들어 하는 아이디어 창출에 있어서, 또 다른 시스템적인 아이디어 창출 방법을 제안한 것이다.

The labeling for functionality of food or food components are recognized globally and are essential for the growth of dairy product industry. To expand the functional claims of dairy product especially fermented milk product, the regulations restricting the labeling of functionality should be amended as soon as possible. The labeling regulations of functionality and efficacy for processed and functional foods in related Acts and subordinated statues such as definition, scope of claims, etc. were reviewed and the problems existed in the system were identified. The definition and classification of efficacy for processed food in Food Sanitation Act were analyzed to revise the labeling regulation of dairy product. A draft of amended labeling regulation for the functionality of dairy product is proposed, which provides consumers with appropriate information of beneficial effects on health purpose for human body structure and function. In order to develop the dairy products and related industries, these contents should be considered when the annexed Table 14 in the Enforcement Rule of the Processing of Livestock Products Act is amended.

A new high contrast LCD structure for TN mode TFT-LCD, of which the contrast ratio is 1.2 times hi gher than that of the conventional one, has been developed. The contrast ratio of TFT-LCD display can be improved by some modified materials, which like as polarizer, liquid crystal, color filter and light enhancement film. In order to know which condition can get the major contribution for the upgrade of the contrast ratio, we used Taguchi method and analyzed the contribution ratio for each composition and succeed to build up the formula of contrast ratio. From this study, we could achieve the highest CR value as 1200:1 of TN mod e TFT-LCD nowadays.

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 for product safety management program than any other risk management standards in view point of broad definition of risk concept including opportunities of loss and gain, stepwise composition of management processes applicable iteratively, and integrable form of structure addible to existing 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 proposed by AS/NZS 4360.

This paper describes a comprehensive approach to examine how technological innovation contributes to the renewal of the firm's competences through its dynamic and reciprocal relationship with R&D and product commercialization. Three theories of technology and innovation (R&D and technological knowledge concept, product-process concept, technological interdependence concept) are used to relate technology and innovation to strategic management. Based on those theories, this paper attempts to identify dynamic relationship between product innovation and process innovation by system dynamics, by investigating the aspect of the dynamic changes of the closed feedback circulation structure in which R&D investments drive technological knowledge accumulation, and such knowledge accumulation actualizes product innovation and process innovation, subsequently resulting in the increase of productivity, customer satisfaction, profit generation, and re-investment on R&D from the created profits. This provides the ability to assess the advantages and disadvantages of different technological innovation strategies and commitments, and the opportunity to explore equilibrium point and suggest a generalized technological innovation model under different industry environment parameters and time-strategies.

This paper considers a reverse supply chain with simultaneous recovery of used products and manufacturing of brand-new ones. Recovered products are downgraded and have to be sold in a market different from that of brand-new products at a different price. In case of a shortage of recovered product inventory, a brand-new item, if available, can be offered at the price of a recovered product. In other words, one-way demand substitution is allowed. We address the joint decision of when to manufacture brand-new product, when to recover returned product, and how to control demand substitution to maximize the hybrid production system's profits. To this end, we propose a Markov decision Process model and investigate the structure of the optimal policy. Performance comparison is numerically implemented between the models with and without downward demand substitution option under different operating conditions of the system parameters.

We propose a new generic design methodology for different types of PSS. Product - Service System (PSS) has received much attention recently from academia and industry because of its benefits. PSS can provide customers values and functionalities, as well as physical products, to fulfill economic, social and environmental goals. Many methodologies have been proposed for designing PSSs. Most of the existing methodologies are domain specific and were proposed to solve specific problems in certain projects. Some methodologies are generic but they provide neither guideline to practitioners and designers nor reflect the differences in various PSS types. As a generic approach to guide practitioners and designers in designing PSS effectively, the proposed methodology also takes into account user involvement, business model and organizational structure. The proposed methodology is demonstrated through design examples of different types of PSSs.
