The purpose of this study is to estimate the determinants of product design and analyze the impacts of product design on quality competitiveness, product reliability, and consumer satisfaction in an attempt to provide a foundation for the theory of design management. For this empirical analysis, this study has derived the relevant measurement variables from a survey on 400 Korean manufacturing firms during the period of $August{\sim}October$ 2003. The empirical findings are summarized as follows: First, the determinants of product design are very significantly (at p<0.001) estimated to be the R&D capability, the level of R&D expenditure, the level of innovative activities(5S, TQM, 6Sigma, QC, etc.). This empirical result can support Pawar and Driva(1999)'s two principles by which the performance of product design and product development can be simultaneously evaluated in the context of CE(concurrent engineering) of NPD(newly product development) activities. Second, the hypothesis on the causality: product design${\rightarrow}$quality competitiveness${\rightarrow}$customer satisfaction${\rightarrow}$customer loyalty is very significantly (at p<0.001) accepted. This implies that product design positively affects consumer satisfaction, not directly but indirectly, by influencing quality competitiveness. This empirical result of this study can also support the studies of for example Flynn et al.(1994), Ahire et at.(1996), Afire and Dreyfus(2000) which conclude that design management is a significant determinant of product quality. The aforementioned empirical results are important in the following sense: the empirical result that quality competitiveness plays a bridging role between product design and consumer satisfaction can reconcile the traditional debate between QFD(quality function development) approach asserted by product developers and conjoint analysis maintained by marketers. The first empirical result is related to QFD approach whereas the second empirical result is related to conjoint analysis. At the same time, the empirical results of this study can support the rationale of design integration(DI) of Ettlie(1997), i.e., the coordination of the timing and substance of product development activities performed by the various disciplines and organizational functions of a product's life cycle. Finally, the policy implication (at the corporate level) from the empirical results is that successful design management(DM) requires not only the support of top management but also the removal of communication barriers, (i.e. the adoption of cross-functional teams) so that concurrent engineering(CE), the simultaneous development of product and process designs can assure product development speed, design quality, and market success.

In this study, variables were constructed based on previous studies to examine the effects of overseas direct purchase quality factors(information quality, system quality, and service quality), perceived value, and purchase intention. In addition, differences between groups were examined through the moderating effect of price sensitivity. A survey was conducted on overseas direct purchase users, and 178 questionnaires were used for empirical analysis. The collected data was analyzed by SPSS 25.0 and AMOS 21.0. The results are as follows: First, it was found that the quality factors of overseas direct purchase had a positive effect on perceived value. Second, it was found that the quality factors of overseas direct purchase had a positive effect on purchase intention. Third, as a result of testing the moderating effect of price sensitivity in the relationship between the quality factors of overseas direct purchase, perceived value, and purchase intention, there was no difference between groups. In conclusion, the implications and limitations of this study are presented.

농산물은 기후와 시장동향에 따라 물량, 품질, 가격이 변동하고 산지에 따라 상품규격이나 품종이 다양하기 때문에 적기에 수출물량을 공급하고 지속적으로 확보하는 것이 어려운 문제로 대두되고 있다. 따라서 앞으로 농산물의 국제 경쟁력은 상품의 고품질화와 시장의 변화에 따른 상품의 안정적 공급에 달려 있다고 할 것이다. 연구결과에 의하면 작물이 안정적으로 생장하고 고품질의 수확물을 지속적으로 생산하기 위해서는 적정 일일적산광합성유효광양자속을 균일하게 공급할수 있어야 한다. (중략)

In spite of various studies on the service quality of customer center, the previous studies are mainly focused on the studies on the relationship between customer satisfaction and loyalty, rather than on the evaluation model of service quality. In this study, we reviewed the service quality of customer center factors discussed in previous studies and developed a hierarchical model for measuring customer service quality based on Brady and Cronin's (2001) model. The first level consists of interaction (process) quality, physical environment (system) quality, and outcome quality, and the second level consists of kindness, positiveness, professionalism, systematic, convenience, accessibility, accuracy, promptness, and reliability. In addition, based on the developed hierarchical model, the priority of each factor that customer center users consider important is analyzed by AHP methodology. As a result, the interaction quality was important in the first level, and professionalism, kindness, and accuracy were important in the second level. Such a study can be a guideline for establishing a standard for evaluating the service quality of customer center or for managing more importantly in practice.

Recently internet protocol television (IPTV) service is becoming a typical emerging service enabled on broadband networks. Through the Internet which cannot support quality of service (QoS) beyond best-effort (BE) policy, how to manage and maintain its service quality is an important and essential issue for successful deployment and settlement of IPTV service. In particular, the current measurement scheme that mostly depends on specific equipments should be replaced with one that supports realtime and constant measurement achieved on a user's own will. Therefore, this paper proposes a scheme so-called 'user centric realtime measurement' of IPTV service. The developed software, which is installed in a set-top box (STB) at a user's premise, measures and reports the quality of IPTV service in realtime. In order to verify the performance and accuracy of the developed software, a number of tests are performed comparing to the measurement values from two major measurement equipments. The result of the tests shows that the measurement by the implemented software is significantly reliable.

The mass housing supply policy of the government has resulted in the customer-centered market, and thereby the age of quality competition in the industry. In line with this trend of quality competition, therefore, this preliminary study aims to investigate the requirements of housing product planning to live up to the needs of customers in terms of quality, and thus analyze the types of quality differentiation of a housing product unit in our housing market. It turned out that many cases attempted differentiation in such ways as merely using luxurious finishing materials and instantly popular environment-friendly materials, and combining partial and limited household items with architectural elements of the facility system. The result of this study shows that the differentiation plan of housing product should be customer-centered, and therefore, focus on quality differentiation through organic combination of architecture-oriented plane and interior elements with technology-oriented facility and product elements. Hereby, in the future, housing product planning should include sustainable differentiation plans with reconsideration of concepts that customers have, and the needed procedure.

This paper examined whether quality management(QM) positively impacts Kazakh companies' business performance (financial and non-financial performance). As a result of testing ten hypotheses based on the research model for 287 companies in Almaty, only eight hypotheses were supported. Top management leadership was identified as a critical factor that positively affected financial performance, and customer-centered thinking is strongly related to non-financial performance. Employee participation and quality information analysis factors also positively affected business performance, but their influence was lower than top management leadership and customer-centered thinking factors. Finally, the supplier management factor did not significantly affect business performance, and the two related hypotheses were not supported. These results are presumed to be due to the characteristics of the target companies, such as oil and raw material manufacturing and construction, rather than high-quality finished products.
