The purpose of this study was to identify the consumers who use the level of price as the indicator of the product quality. In order to implement the purpose of this study, Jeans market had been segmented by the mixture regression model, and price response function was calibrated for each segment. Based on the types of price response function, segments were allocated into one of two groups; the group using the level of price as the quality indicator or the group not using the level of price as that. Then, characteristics of both groups were compared in terms of product attributes and demographic variables. Data were co]looted from the sample of the 23o undergraduate and graduate students in Seoul. For the data analysis, mixture regression model, conjoint analysis, and t-test were used. As a result, jeans market was divided into 5 segments. Segment 1,2,3 were allocated into the group not using the level of price as the quality indicator while segment 4,5 were done into the other group. Significant differences existed between two groups in product attributes, not in demographic variables. Mixture model and conjoint analysis were proved to be an effective set of tools in market segmentation.

발전용 연료로 사용하는 석탄은 취급의 어려움과 가스 및 석유에 비해 품질이 낮은 단점이 있으나, 매장량이 풍부하고 가격이 저렴하여 발전용 연료로의 사용은 더욱 증대될 전망이다. 이에 따라 석탄의 안정적 수급 측면에서 구입원의 다양화가 예상되고 있으나, 현재 발전용 연료의 연소특성 평가는 주로 실험실적 기초 시험에 의존함에 따라 정확한 평가가 곤란한 실정이므로 시험연소로를 이용하여 각종 연소특성을 비교 평가하여 탄종별 최적 연소조건 규명과 적정 흔탄비에 대한 Data Base를 구축하고자 한다.(중략)

본 논문은 모선가격을 적용하는 계통에서 전력품질기준을 초과한 수용가에 대한 보상을 하는 것이 계통계획상의 의사결정에 어떠한 영향을 주는가에 대한 시험 연구 결과이다. 우리나라는 산업의 고도화에 따라 전력에 대한 산업의 의존 비율이 대폭 증가하였을 뿐만 아니라, 전력품질에 대한 산업체의 요구조건도 과거에 비해 매우 높아졌다. 그러나 현행 계통계획과 전력요금제도에는 이러한 사회적 변화를 반영할 품질에 대한 요소가 포함되어 있지 않으며, 이에 대한 적절한 대비가 되지 않음으로 인한 사회적 비용은 제대로 평가되지 못하고 있다. 본 논문에서는 수용가에 대한 전력요금이 모선별로 할당되는 경우에 각 모선의 전력품질이 측정가능하고 이를 보상비용화 할 수 있다고 가정하는 경우, 이를 계통계획에 반영하였을 때 예상되는 효과를 모의계통을 통하여 시산해보고 그 결과를 토의한 것이다. 그 결과, 전력품질의 비용을 반영한 경우, 전력요금은 상승하지만 전체 비용을 최소화하는 요소설비에 투자하는 방법을 선택함으로써 총괄비용을 감소시키는 효과를 거둘 수 있다.

With the continuing development of the global economy, the scale of international production and management of companies is expanding rapidly nowadays. As a result, it is increasingly important for multinational companies to establish appropriate marketing strategies for products in order to successfully enter overseas markets. When consumers evaluate the quality of products from various countries, they depend heavily on the image of the product as well as the price of the product. Therefore, this study aim to find out how the price, country image, brand image and country of origin image affect on consumer product evaluation and purchase intention. Based on these concepts, the significance of this study is helping local companies make more appropriate marketing strategies by understanding the importance of price and image of a product to companies and knowing more accurate recognition in Korea and Korean-made products of Chinese consumers. The results of this study which used AMOS model showed that 1) The country image and country of origin image for a product had a positive effects on product quality, 2) The price and country image of a product had a positive effects on service quality, 3) And evaluation of product had a positive effects on purchase intention. Based on these results, we made some proposals and presented the future research directions according to the limitations.

Amethyst is a precious stone in Korea. As natural quartz are usually mixed with smoky quartz, amethyst, and milky quartz, we need to evaluate the amount of the amethyst quantitatively in ores. Although the optical evaluation with bare eyes has been common in assay so far, we propose that the diamagnetic property and microstructural difference characterization be the solution for the evaluating the quartz ores. In addition, FTIR (Fourier transformation infra-red) could help to identify the amethyst transparency. We report that we could evaluate the amethyst quantitatively with M-H hysteresis characterization, transmission electron microscopy (TEM) observation and FTIR characterization.

The product categories that can be sold on-line are expanding. It is interesting to see which product categories have more sales possibilities on internet. Small-sized firms' products have low distribution coverage, low brand recognition, bigger dispersion in the perception on the values which consist of quality vs. price, and higher possibilities of perceived purchase risks. Since on-line shopping is supposed to provide opportunities to small-sized firms that have low distribution and brand power, it is quite necessary to evaluate the fitness of on-line sales for small-sized firms' product categories. There are virtually no research studies on the on-line sales for small-sized firms' product categories. In this study, based on the integration of SEC, FCB, and related concepts, we develop new theoretical framework and test the fitness of on-line sales for small-sized firms' product categories by conducting empirical analysis. The empirical results on 17 product categories show that SEC, FCB, purchase risks, brand factors are somewhat related. Unlike previous studies, since the fitness of SEC and on-line sales are not clearly shown, we need to consider those problems within inter-related multiple frameworks. That is, it is necessary to evaluate the fitness of on-line sales after defining the product categories within the integrated multiple frameworks rather than within the single framework.
