The emotional quality of the product have become an important factor in purchasing decision. Classical approach of product design has focused on providing proper functions of the product. However, as the life-cycle of products become shorter and the customer's needs get more diversified, it is now necessary to accommodate the customer's emotional requirement in product design. This study aims to analyze and interpret the emotional characteristics based customer preference survey. This study consisted of two part. First part was to search the optimal combination of design variables through DOE of predetermined 5 design variables. In the second part, we developed customer preference index model to measure the customer preferences about 16 different wood flooring product.

Mechanical characteristics of nodular graphite cast iron has found to tan higher utilization to the gray cast iron. So, Nodular graphite cast iron is used as a basic material in mechanical industry. Great demand of Nodular graphite cast iron is expected to increase due to the sharp development in mechanical and automobile industry. Therefore, Nodular graphite cast iron requires not only good quality product but experienced skills in manufacturing process. But there exist a lot of difficulties to manufacture nodular graphite cast iron than gray cast iron in manufacturing process. In this study, the following topics are studied for good quality product of nodular graphite cast iron. $\circled1$ Activities of managerial staff. $\circled2$ Qualite control method in manufacturing process. $\circled3$ Manufacturing process system. As a result of the study, a intensive Quality control activities should be applied and reinforced at each stage of manufacturing process rather that at the last stage of final product.

시대변화에 따라 제품에 대한 소비자의 구매 결정기준과 제품 공급방법은 끊임없는 변화가 거듭되었다. 디지털기술을 응용한 on-line 시스템이 상품에 대한 정보를 전달하고 생산과 구매가 동시적으로 일어나는 시장체제가 형성하게 되었다. 그 결과 소비자 중심의 브랜드 구축이 중요한 과제가 되고 있다. 따라서 실증조사를 통하여 경제 사회 환경 변화에 따른 소비자의 의식구조를 파악하고, 이 변화에 따른 소비자의 구매결정 기준을 이해하고자 한다. 소비자의 구매태도를 만족, 선호, 재구입, 추천으로 기준을 설정하고, 이들 4개의 기준에 미칠 수 있는 브랜드 이미지의 요인들의 영향을 파악하였다. 브랜드 이미지의 효율적 형성을 위하여서 생성되는 소비자(고객) 중심의 브랜드 가치는 실증분석을 통하여 얻어진 결과를 보면 사회생활가치, 정서가치, 개성적가치 수용하여 브랜드이미지에 적용하는 것이 효과적인 것으로 나타났다. 연구결과에서 도출된 브랜드 이미지의 공통적 요인으로는 차별성가 고객 중심의 일관성 및 개성적, 감성적 요인들을 부각 시를 수 있는 행태로 브랜드 이미지화를 도모할 필요가 있다는 결과가 나타났다. 따라서 본 연구는 미래 지향적이고, 소비자에게 인지 연상되는 기능을 보다 효과적으로 증대시킬 수 있도록 고객 중심의 브랜드 창출을 위한 가이드라인을 제시하였다.

This essay talks about research of robust design for quality improvement of production procedure of Wet Etchant. It suggested the optimum design method in consideration of specific capability value that is the way to maximize the quality of product in the production system by using Daguchi parameter design method while finding factors affecting product quality with analysis of production system of product A from producer D. Also, it set long term of 6months as noise factor and let it to be the robust design that can find the optimum condition of control factor that is dull to the changes of each month, that is the change in noise factor. The control factor which affects the product quality is decided as combination method, temperature of raw material, combination time and as there are too many possibilities for combination methods, we performed 4 methods first based on previous research data then derived three ways with product that passed SPEC and set as the factor. As a result of application of optimum production procedure suggested in this essay to the actual production process with its standardization, there was a effect of drop of more than 10particles in comparison to the particle number of previous product and also it brought the effect that resulted the stable number of particle of under 30 that is what the client company suggested.

Yu Ja cheong(Citron product) one of the traditional drinks was processed by a modified method to improve the quality,. Sugar(38%) and sorbitol(12%) were added as partially substi-tuted sugar and experimented about quality stability during storage at 20$\pm$2$^{\circ}C$ comparing with conventional 50% sugar added product. Chemical compositions of the acidity 40. 46mg% total Vitamin and 28.5mg% amino-N and pH was 3.7 During the storage pH reducing sugar and amino-N contents increased slightly while total acididty decreased slightly and reduced vitamin C occupied most part of total vitamin C after proessing was converted to oxidized vitamin C greatly at 70 days of storage. While L a and b values deceased in between modified one and conventional product. e value increased continually during storage {{{{ {C }_{16 { }:_{ } 0 } }}}} {{{{ {C }_{18 { }:_{ }0 } }}}} {{{{ {C}_{18 { }:_{ }1 } }}}} and {{{{ {C }_{18 { }:_{ }2 } }}}} contnts in fatty acid and citric acid itaconic acid malic acid and succinic acid in organic acid were the major componets in both products. Judging from the results of experiments during storage the quality of the modified product was compared quite well with that of vonventional one during storage.

Software quality is classified by quality of process and product. In experience of Quality Management, it is known that quality level of product as it depends on goodness and badness of process and organization. As a result, improvement of software process has been important subject. According as this trends, ISO 12207 is publicated as standard of software life cycle process by ISO. For UML based object oriented development process, it is necessary that we should research detailed definition of activity and task of ISO 12207 process which is added, deleted or tailored in according to organization and project characteristics. In this thesis, by according with ISO 12207 software life cycle process, UML based object oriented development process is proposed. This process is composed of 7 steps and 19 activities including development phase, activity and product to improve quality of reliability. Usefulness of object oriented process for improvement of software quality is proved at three ways, which are comparative analysis of process characteristics, SPICE process evaluation and SPICE rick analysis.

Robust design in industry is an approach to reducing performance variation of quality characteristic values in products and processes. In the Taguchi type robust design, the product array approach using orthogonal arrays is mainly used. However, it often requires an excessive number of experiments. In this paper, for the combined array approach to assign control and noise factors, we propose how to simultaneously optimize multiple quality characteristics. Two examples are illustrated to show the difference between the product-array approach and the combined-array approach.
