We proposed eight dimensions and their constituents of product advantage in the last issue. In this study, using the dimensions and constituents, gap analyses are conducted on some product categories(; desktop computer, PCS terminal, and washing machine) in order to know what dimensions or constituents are major areas to be improved. For the purpose of strategic use of the dimensions of product advantage, Kano analyses are also applied. Based on the results of the gap analyses and Kano analyses, the future directions of new products development for the selected products are suggested.

In order to examine the determinants of new product success, winning products are analyzed with a focus on merchantability. The specific dimensions of product advantage have not been studied as yet. As results of the analysis, the determinants are classified into function, aesthetics, economy, safety, usability, reliability, brand image, assurance, distribution channel, advertisement, DEF(design for the environment). This study augmented the data set through questionnaire survey to marketing professor in University. The results of this study would be a cue to the future direction of new product development and to management of exist product.

The Quaternionic Dirac operator proves instrumental in tackling various challenges within spectral geometry processing and shape analysis. This work involves the introduction of the quaternionic Dirac operator on a symplectic submanifold of an exact symplectic product manifold. The self adjointness of the symplectic quaternionic Dirac operator is observed. This operator is verified for spin ${\frac{1}{2}}$ particles. It factorizes the Hodge Laplace operator on the symplectic submanifold of an exact symplectic product manifold. For achieving this a new complex structure and an almost quaternionic structure are formulated on this exact symplectic product manifold.

Many studies in marketing and economics have attempted to model price and sales path under the dynamic diffusion process. Most of these models have been based on a fixed product lifetime. The current business climate requiring intensive development of new products however affects the diffusion of new products and their lifetime. Many products have not enjoyed the expected life cycle at the launching stage due to intense technical development competitive reactions, and financial problems. Most diffusion models however have not taken account of the lifetime uncertainty of new product. If the products do not last over the planning horizon set by those models. the optimal price derived from them could be futile. Therefore we had better take such lifetime uncertainty into consideration when developing diffusion models, In this paper we study the impact of uncertain product lifetime on its optimal pricing path in non-competitive market. We develop an optimal pricing model under uncertain product lifetimes and conduct a simulation study to investigate their effects on the optimal pricing and corresponding sales paths. The simulation study provides some interesting findings on optimal pricing policy under uncertain product lifetime. This study could be a stepping stone for the further extended study of optimal pricing strategy with uncertain product lifetime.

Affordance is a kind of mental physiology, used by psychologist Donald A. Norman as a design idea, defined as "the property that something can directly and essentially provide something to a person or animal". This idea of returning to the essence and providing properties intuitively has a new guiding effect on product design. The purpose of this thesis is to take the theory of affordance as the basis of design concept, and redesign the shape of desktop lamps in small home appliances, so as to optimize the product shape. A product styling design method based on the concept of affordance is established through four major classifications of affordance, and a styling design scheme is completed using a tabletop luminaire in small home appliances as an example, and then a product styling design evaluation system is used to evaluate the new tabletop luminaire styling design scheme and the existing styling, and the evaluation results are analyzed. Finally, it is concluded that a new product styling design method based on affordance is constructed, and the feasibility and effectiveness of this method are verified, which provides ideas and theoretical basis for product styling design.

Purpose: In developing new products, reducing performance variation is important for competitiveness factors such as quality, cost, and delivery. This paper aims at evaluating three performance variations; measurement, performance evaluation, and manufacturing variations, and then improving product and process design, focused on paper helicopter making case study. Methods: For measurement system analysis, gage R&R (repeatability and reproducibility), linearity, stability are evaluated. Since gage R&R are not satisfactory, the measurement system is improved by adopting voice memos application of iPhone and providing standard measurement procedure. To evaluate performance variation, product deterioration and environment factor (wind speed) is considered. Since the existing design is sensitive to these noise factors, a new product design is developed, which is proven to be robust to the noise factors. Finally, manufacturing variations are evaluated with five factors which can cause variation in flight time. To reduce the impact of three significant factors, three improvement methods are applied. Results: Three performance variations are evaluated and robust paper helicopter design is presented. Conclusion: To reduce measurement and process variations, improved measurement method and paper helicopter making procedure are proposed. A new product design is also presented which is robust to deterioration and environmental variation. This paper is expected to benefit students and practitioners who want to have hands-on knowledge on new product quality improvement.

현재 신제품 출시전에 인터넷 상에서 출시 전 제품에 대한 커뮤니케이션 활동인 프리어나운싱 활동이 활발하게 시행되고 있다. 특히 이러한 프리어나운싱 관련 정보들은 제품 관련 인터넷 커뮤니티에서 확산 되어지는 상황이다. 이에 본 연구는 신제품의 프리어나운싱 맥락에서 인터넷상에서의 신제품의 프리어나운싱 활동이 인터넷 유저들의 e-WOM(electronic word-of-mouth)에 미치는 영향을 살펴보고자 한다. 더욱이 현재 인터넷 커뮤니티 상에서 e-WOM 활동은 블로그, 트위터 등으로의 포스팅으로 연계되어 구전활동이 가속화되고 있는 상황에서 이러한 인터넷상에서의 포스팅 의도에 대한 신제품정보의 생동감의 영향을 살펴보면서, 특히 정보의 생동감을 외적인 생동감과 내적인 생동감의 차원으로 그 영향을 고찰하고자 한다. 연구 결과 신제품 정보의 외적인 생동감과 내적인 생동감이 인터넷 커뮤니티 e-WOM에 긍정적으로 영향을 미치고 있으며, 또한 인터넷 커뮤니티 내 e-WOM는 유저들의 웹포스팅의도에 긍정적인 영향을 미치는 것으로 나타났다.
