The market for second hand products has been growing for a variety of reasons (e.g., new products appearing at a faster rate and the expected life of products increasing due to rapid advances in technology). The demand for warranties for second-hand products has been growing along with the growth of the market for second-hand products. Warranty for new products (consumer durables, industrial and commercial, and specialized defense products) has received a lot of attention. In contrast, warranties for second-hand product have received very little attention. Often, dealers of second-hand product such as cars offer 2D-warranties (Year and Kilometers). The expected warranty cost associated with a second-hand product for 2D-Policies is a function of the age of the item and its usage (as it affects failures over the warranty period), the warranty terms and the servicing strategy used by the dealer. This paper deals with development of models for warranty cost analysis along with the decision on sale price and warranty cover for 2D-Warranty policies associated with sale of second-hand products.

This research was accomplished to prove that the actual using conditions of the funtional bakery products would be different by their sex, age group and income, and what would be main factor to choose them. This survey was examened for 268 subjects by the self-administered questionnaire method. 37% of subjects used the funtional bakery products once or twice a week. They normally paid for them 1,000-3,000 won(40%). The biggest merit of the fuctional bakey products was good for health, but high price was the weekest point of them. Over 63% of subjects answered they had the will to use the new functinal bakery products if they would be developed. Mainly they got the information of functional procuts in bakery. Females paid more than males to buy them and had stronger will to use the new procuts. As the age increased, the using frequency of fuctional bakery products also increased. The expences to buy for them once and the will to use new products increased according to income increment. Females thought more important factors as price, taste, and color than males. Twenties and forties answered price was more important than thirties and fifties.

This paper investigates changing processes of new product development (NPD) systems. In order to continuously develop first-class products, world wide super-class products and hit products, R&D (Research & Development) must be competitive. Firms must achieve competitiveness in terms of quality and cost by launching new products. Most films focus on improving effectiveness and efficiency of NPD process. However, sometimes, they face to the critical challenge of transforming NPD processes entirely reflecting dramatic change of their core products. Transforming of NPD process is difficult in that it involves technological and organizational changes in marketing, R&D, Engineering and manufacturing systems. The purpose of this paper is to shed light on processes and factors affecting successful transformation of new product development systems. We present a case study on the changing processes of S company's NPD process. S company has changed new product development systems successfully from a major IT equipment supplier to an automotive supplier. Empirical results show successful changes of 10 core NPD processes from understanding the market and customers process to after sales process. In case of transformation of NPD, adaption of attribute of business is crucial for success factors in the process innovation. This paper shows the bridging the gap between IT and automotive industrial dynamics and growth through adaption of two processes in the NPD.

Reduced life-cycle and scale of electronic products make the conventional automated manufacturing system difficult to keep on competitiveness in these days. Reduced life-cycle requires an agile adaptation of manufacturing to new products and reduced scale requires enhanced precision as well as high speed. In this research, We propose a new concept called as "One-Cell Minifactory" in which various processes are combined to produce final modules or products and human interaction can be combined easily. We hope the proposed concept can guide new developments of automated manufacturing in electronics, optics and bio-engineering.

Many researches have concluded that product advantage or superiority is the most important factor for the commercial success of new products. However, the specific dimensions of product advantage have not been studied as yet. Based on a survey of newly introduced products in recent years, we suggest the eight dimensions of quality of new product: function, time, limitation, usability, problem prevention, economy, maintainability, nativeness. The dimensions and their constituents are explained with examples.

Aconiti Tuber (Aconitum spp. tuber, Ranunculaceae) which contains bioactive but toxic alkaloids has been used as analgesic. cardiotonic, diuretic. and stimulant. We have previously reported two new C-19 norditerpenoid alkaloids and five known norditerpenoid alkaloids. Further study has now led to the isolation of two new norditerpenoid alkaloids. 14-O-anisoylneoline and 14-O-veratroylneoline. (omitted)

The purpose of this paper is 1) to extract managerial factor into each cell which is classified by the characteristic grill of new products 2) to construct a management model of new product development for korean companies. For this purpose, the characteristic grill of new products is classified by which is market/technology sphere. Moreover the focus of this analysis is on examination of success/failure factors, which have an important effect upon new product success or failure. The variables for this study were selected from literature survey and pre-interview was implemented specially. The subject of study was project leaders of electronics industry where have taken the leading part in product development activities in Korean manufacturing industries. Enquete survey was conducted in each firm and project managers were asked to respond. Conclusion of this study based on many significant results gained by the various multi-variate analysis are summarized as follows. First, it can he noted that success/failure factors are different by each classified model and characteristic grill of a new product. Second, it has been identified that the important factors of success products were technical & management support and market ability, the important factor of failure product were lacking in ability of technical development and R&D management system construction. This paper presents some useful guidelines in strategic and managerial aspects for development of new products. Concurrently, the model of this study should be a great practical approach for application of actual affairs.

추천시스템에서 가장 많이 활용되고 있는 협업필터링은 고객들의 과거 구매이력을 기반으로 추천하기 때문에 새로이 출시되는 상품을 추천하는 것이 근본적으로 불가능하다. 이와 같은 협업필터링의 한계점을 극복하기 위하여 많은 연구자들은 추천 대상 고객이 선호하는 상품과 유사한 속성을 가진 상품을 추천하는 내용기반 필터링을 협업필터링과 결합한 하이브리드 추천기법을 제시하였다. 그러나 하이브리드 추천기법은 음악, 영화 등 속성 추출이 용이한 일부 상품의 추천에만 활용될 수 있다는 한계가 있다. 따라서 상품 유형에 관계없이 고객에게 신상품을 효과적으로 추천할 수 있는 새로운 접근방법이 제시될 필요가 있다. 본 연구에서는 사회연결망분석에서 관계 및 구조적 특성을 분석하기 위해 널리 활용 되고 있는 중심성 개념을 적용하여 상품간의 구매 관계를 파악한 후 이를 기반으로 신상품을 구매할 가능성이 높은 고객을 찾아 신상품을 추천방법을 제안한다. 추천 프로세스는 구매 유사도 분석, 상품 네트워크 구성, 중심성 분석, 신상품 추천 등 네 단계 절차로 나뉘어진다. 제시한 추천방법의 성능을 평가하기 위하여 국내 유명 백화점 중의 하나인 H백화점의 구매 데이터를 사용하여 실험하였다.
