This study reviewed primary care purchasing issues of the Indonesian single-insurer, BPJS-K, in the context of triangular power relations between the government, the insurer, and the providers, and considered its challenges of purchasing as the national single-insurer. Some literature reviews and interviews with Indonesian stakeholders and residents were used to describe the historical and social contexts of Indonesian healthcare and social health insurance systems especially focusing legal and institutional status of BPJS-K and primary care provision and delivery conditions in remote areas. Though BPJS-K directly belongs to the presidential office of Indonesia, it has limited power in terms of purchasing as a single insurer. Mainly it was due to the lack of primary care resources, Ministry of Health's strong power as the regulator and provider, and BPJS-K's powerlessness against monitoring and quality of care assessment. Ambiguous accountability was another issue among the insurer and the Ministry of Health. This created confusions in primary care provision. It is suggested that each agencies' accountability should be obvious in terms of legal, political, and social contexts.

본 연구는 청바지 제품 소비자가 쇼핑시 제품이 품절된 상황에 접했을 때 보여주는 상표 전환행동에 관한 것이다. 의류 매장 관리자의 적시 적량의 제품 입고 관리 능력이 부족할 때 발생하게 될 손실을 유추해 보고 어떤 유형의 소비자가 상표 전환을 쉽게 일으키느니를 규명하는 것은 더욱 효과적인 매장 운영 소비자 만족과 고객 관리를 위해 의미있는 일일 것이다. 본 연구는 다음과 같은 목적을 가진다. 1) 제품 품절시 소비자들은 어떤 상표전환 행동을 보이는지 밝힌다. 2) 제품 품절시 대체 상표제품을 구매할 경우 대체 상표 제품의 가격의 영향력이 상표전환 행동과 어떤 관련을 보이는지 밝힌다. 3) 소비자의 쇼핑지향성, 상표충성, 애고 행동, 인구통제적 특성(성별)이 상표전환 행동에 미치는 영향력을 밝힌다. 이러한 목적을 위해 본 연구는 1997년 3월 버지니아주 블랙스버그에 소재한 버지니아 주립대학교 110명의 학생들을 대상으로 설문조사를 이용한 양적연구를 실시하였다 남녀학생 모두가 소비자로서의 역할을 담당할 수 있는 청바지를 선택하여 상표전환 행동에 대한 설문에 답하게 한후 t-test 와 카이 분석을 실시하였다 그결과 20%의 응답자가 품절기 상표전환 행동을 보이는 것을 나타났다 쇼핑시간과 편의성을 덜 중요하게 여기거나 강한 상표 충성을 보이고 의류전문매장이나 백화점을 주로 이용하는 여성 소비자들의 경우 상표전환을 쉽게하지 않는 것으로 나타났다 연구결과를 바탕으로 의류제조업자 및 소매업자의 제품입고에 과한 제언을 하였다.

The purposes of this study were to classify shopper types based on clothing shopping orientations and to identify the differences in store selection criteria and demographic characteristics by shopper types. The questionnaire was administered to female and male undergraduate and graduate students living in Seoul. Of 330 returned questionnaires, 319 were used in the statistical analysis which were factor analysis, cluster analysis, $\chi$$^2$-test, and One-way ANOVA. The results of this study were as follows: 1) Clothing shopping orientations had six factors: recreational shopping, name conscious shopping, economic shopping, fashion oriented shopping, convenience shopping. and individualistic shopping. Cluster analysis identified that clothing shopping orientations had four groups: recreational cluster, individualistic cluster, demanding shopper cluster, and convenient brand conscious shopper cluster. 2) Clothing shopping orientations were significantly different in relation to the demographic characteristics such as gender, major field of study, expenditure on clothing, pocket money, and family income level. 3) Store selection criteria had five factors: service quality, physical store environment, sales personnel, shopping convenience, and other attractions. 4) There were significant differences in physical store environment, shopping convenience, and other attractions according to the shopper clusters.

The purpose of this study was to identify the sizing problems for shoes, and provide improvement information for shoe industries in internet shopping mall. For this, the study was conducted through a survey with 611 young women consumers from late 10s to late 20s. In addition, we investigated the actual conditions of shoe size system from manufacturers and vendors of internet shopping mall. On the survey from consumers, it was revealed that the main reason which makes the consumers hesitate to purchase is the difference between the image or size shown by the monitor and the actual product. Also, the problem was substantiated through status of internet shoe vendors. Moreover, it was found that consumers rarely have the knowledge of the letter sizes for the foot girth at purchasing shoe. To overcome the problems of shoe size system in internet shopping industry, the new sizing system that both consumers and vendors can satisfy is needed immediately.

In my previous research (1986), I considered a general characteristics of a visual image of products. There were really many difficulties in designing all kinds of needs in compliance with the all of their requests in order to satisfy consumers. In addition, under the characteristics of goods, the consumers seem to choose an opti$$\mu$ com\ulcornerbinations after considering the combinations of trade-off. Therefore, this study that selected a watch as an object on this study was analyzed a Design Assessment Structure under the trade-off. As a result of this research: First, an effect of a negative superiority appeared under the trade-off condition among ifems when consumers purchased products. Second, these four items were extracted from the eight items which were suggested in this study through an analysis of factors. Third, the three courses were conformed when a consumer purchased a watch. Fourth, in the all kinds of goods, the price which was considered as an important point was not important item ina relation to a purchasing behavior. According to the concomitant effects, we figured out these four items, that is, form, thickness, readability and wearing and its have to be considered a lot when designing a watch.

The demand of domestic mobile service has been explosively increasing. The forthcoming WCDMA, which open in 2006, is also a key technology in the mobile service market. The WCDMA service needs HSPDA phones which will be evolved to HSDPA. In the aspect of drawing up management strategy, practical researches about forecasting the demands of new mobile phones are necessary. In this paper, we provide the modified the Lotka-volterra model as a forecasting model, which is concerned with effects of phone prices and performance.

In this paper, we analyze a logistic system involving a supplier who produces and delivers multiple types of items and a buyer who receives and sells the products to end customers. The buyer controls the inventory level by replenishing each product item up to a given order-up-to-level to cope with stochastic demand of end customers. In response to the buyer's order, the supplier produces or outsources the ordered item and delivers them at the start of each period. For the system described above, a mathematical model for a single type of item was developed from the buyer's perspective. Based on the model, an efficient method to find the cycle length and safety factor which correspond to a local minimum solution is proposed. This single product model was extended to cover a multiple item situation. From the model, algorithms to decide the base cycle length and order interval of each item were proposed. The results of the computational experiment show that the algorithms were able to determine the global optimum solution for all tested cases within a reasonable amount of time.

A value net is a business design that uses digital supply chain concepts to achieve both superior customer satisfaction and company profitability. In order to implement the value net model, information processing and distribution needs to occur in real time. Software agent technology is becoming popular due to the inherent characteristics of autonomy, distributedness and modularity. In this paper, we adopt agent technology to handle all real time decision process, making the value net model a complex multi-agent network of decision makers. For the agents to properly coordinate their respective activities we develop MAVN model, a Web-based multi-agent language grounded in the XML and Java.

온라인 소비자들은 amazon.com과 같은 온라인 상점 플랫폼에 상품 평가(리뷰: review) 글을 남김으로써 대상 상품에 대한 의견을 표현한다. 이러한 상품 리뷰는 다른 소비자들의 구매 결정에도 큰 영향을 끼친다는 관점에서 볼 때, 매우 중요한 정보원이라고 할 수 있다. 사람들이 남긴 의견 정보(opinion)를 자동으로 추출하거나 분석하고자 하는 연구인 감성 분석(sentiment analysis)분야에서 과거에 진행된 대다수의 연구들은 크게는 문서 단위에서 작게는 상품의 요소(aspect) 단위로 사용자들이 남긴 의견이 긍정적 혹은 부정적 감정을 포함하고 있는지 분석하고자 하였다. 이렇게 소비자들이 남긴 의견이 대상 상품 혹은 상품의 요소를 긍정적 혹은 부정적으로 판단했는지 여부를 판단하는 것이 유용한 경우도 있겠으나, 본 연구에서는 소비자들이 '어떤 관점'에서 대상 상품 혹은 상품의 요소를 평가했는지를 자동으로 추출하는 방법에 초점을 두었다. 본 연구에서는 형용사의 대표적인 성질 중 하나가 자신이 수식하는 명사의 속성에 값을 부여하는 것임에 주목하여, 수식된 명사의 속성을 추출하고자 하였고 이를 위해 WordNet을 사용하였다. 제안하는 방법의 효과를 검증하기 위해 3명의 평가자를 활용하여 실험을 하였으며 그 결과는 본 연구 방향이 감성분석에 있어 새로운 가능성을 열기에 충분하다는 것을 보여주었다.
