This study aims at providing useful information to establish subdivided marketing direction by deriving factors of significant extent and practicable extent of buffet users toward menu quality among super deluxe hotels in Gyeongju, and furthermore aims at presenting implications for efficient management result and sales increase of buffet in the future. The result of positive analysis is as follows. Firstly, in result of analyzing difference between importance and performance of hotel buffet in Gyungju area, importance is much higher than performance. Secondly, respondents consider that the most important menu of hotel buffet is main dish such as hot food and instant food rather than menu such as beverage, soup and salad. When it comes to attribute of menu quality, it appeared that respondents put highly significant extent on sanitariness of food, freshness of food, flavor of food, and seasonality and variety of menu. Thirdly, oriental instant food is included in the second quadrant of IPA regarding buffet menu which should be intensively managed. And three attributes such as temperature of food, time of changing food, and creativity of menu are included in the second quadrant of IPA graph by attribute of hotel buffet's menu quality. Lastly, in IPA graph by hotel, the following menus of each hotel need to be intensively managed: Oriental instant food of A hotel, Western cold food of B hotel, Oriental instant food, Western instant food, and Oriental dessert of C hotel, and Western porridge soup, Oriental instant food, and Western instant food of E hotel. The aforementioned menus should be improved.

The author analyses the challenging activities of Japanese libraries in this decade by launching two keywords; "product-sharing" and "outcome generation." "Product-sharing" means that libraries share knowledge, skills, and records which are produced as the result of the services or in the process of activities. And "outcome generation" means that libraries generate any efficiency or effectiveness through their services to users. Using these concepts, reported are the current situation and aspects of Japanese libraries which try to make various contributions to the society; research and learning of the people, and education and training for professional librarians, and so on. In the analysis, the author shows some examples of "product-sharing" at first, including the records of reference transaction and the multi-functioned online public access catalogue. Especially, focused is on the various possibility and adoptability of the Collaborative Reference Database System of the National Diet Library of Japan. This system is one of digital reference service in Japan, and the database of reference transaction records is expected to be useful for research and academic studyies as knowledge-base of professional librarians. And the system is also expected to be a platform for LIS education and professional development in the e-learning environment. Secondly, as the examples of "outcome generation", explained are the problem-solving-type activities, and provision of the collection about books on struggling against disease and illness. A few examples of outcome in the problem-solving-type activities are these; increase of sales in the services for shop managers, business persons, and entrepreneurs, contribution to affluent daily life by providing the local information services to residents and neighbourhoods, and etc. And for both the patients with serious cases and their family or those who nurse them, books about other persons' notes or memorandum are the greatest support, and sometime healing. The author discuss the 'raison d'etre' of these activities focusing on public libraries in Japan.

This study investigated organic coffee choice motives from a coffee shop market segmentation perspective in order to understand the potential importance they may have upon attitudes and behavioral intentions to buy organic coffee. A factor-cluster segmentation approach was used for this study. An exploratory factor analysis identified five organic coffee choice motives: 'Sensory', 'Environment', 'Trust', 'Health' and 'Price'. Based upon these five choice motives, cluster analyses classified all respondents into three homogeneous subgroups: 'Highly motivated', 'Moderately motivated' and 'Unmotivated'. Analysis of variance tests indicated that attitudes and intentions to purchase organic coffee were significantly different among the three clusters. In particular, two cluster groups representing 'Highly motivated' and 'Moderately motivated' were found to offer the most utility for further organic coffee market segmentation research. Especially, due to perceptions about high price premium of organic coffee, the 'Moderately motivated' group had higher positive attitudes, although, their intentions to buy organic coffee were not higher than those of the 'Unmotivated' cluster. Findings support previous research propositions that high price could be the strongest barrier for people to purchase organic products including the organic coffee business context. This will assist to market and promote pricing strategies for caf$\acute{e}$s and restaurants to optimize organic coffee sales revenue. Implications for all cluster groups regarding unique socio-demographic characteristics and behavioral intentions are discussed. Organic coffee marketers can apply these findings towards the development of effective target market strategies.

본 연구에서는 에이전트 모형 기반 시뮬레이션 기법을 이용하여 국내 중형 고급승용차 제품시장에서 경쟁 제품들의 확산 다이나믹스를 예측하기 위한 환경조건을 도출하고자 민감도 분석을 실시하였다. 본 연구에서는 소비자의 구매 특성과 행동을 모방한 소비자 에이전트 모형을 이용하며 사회적 네트워크로 연결된 소비자 에이전트들의 집단은 하나의 가상시장을 이룬다. 제품을 구매한 소비자 에이전트가 이웃 에이전트들에게 제품정보를 전달함으로써 실제 시장처럼 구전현상이 나타나고 이는 잠재적 소비자 에이전트들의 제품선택에 영향을 주게 되어 확산 다이나믹스 패턴이 변화하게 된다. 가상시장의 확산 다이나믹스가 실제 시장의 확산다이나믹스를 반영하기 위해서는 초기채택자 비율, 사회적 네트워크의 구조, 소비자 에이전트의 구매시점 결정방법 등의 가상시장 환경설정이 중요하다. 그러나 이러한 환경조건들은 실제시장에서 측정하기가 어렵기 때문에 본 연구에서는 다양한 환경조건하에서의 확산다이나믹스패턴을 실제 데이터와 비교 분석하여 적합한 환경조건을 찾고자 한다.

This study examines, from an economic perspective, the reasons for introducing a resource taxe system into the Korean off-shore fisheries and the type of charges that can be introduced. Following a review of the charging systems in other advanced fisheries, we consider the types of charging scheme and some implications for the Korean off-shore fishing industry. Charges could be used for recovering part of fisheries management cost from the industry(i.e. administration, enforcement, research, etc). This can be justified on the grounds that the fishing industry is the main beneficiary of management and that it should therefore bear at least part of the cost involved. It is arguable that publicly-funded management is in effect a subsidy to the industry. Using charges to raise revenue in excess of the cost of management would represent the extraction of a public rent from the fishery resource, but the short-run financial consqquences for the industry would be significant. Results from a qualtitative analysis suggest that while any new charge will have a significant financial impact on the industry in the short run, a landings tax would have a lesser impact on fleet structure in the long run. The study also considers the possibility of a capital gains tax on license sales in order to recover some rent from the industry. Despite any short run-financial consequences, making the fishing industry pay for at least some of the cost of management could benefit the industry as a whole if there were more cooperation between industry and managers as a result. It is acknowledged, however, that there could be disputes over the relative management costs of different sectors of the industry. Even though this study makes few specific recommendations about charging the Korean off-shore fishing industry, it does advise that the issue be reviewed on the basis of the entire Korea fisheries. Finally, the study notes that insufficient data are available on the economic performance of the Korean off-shore fishing vessels and it recommands that a comprehensive system for the collection of costs and earnings data be put in place. It also suggests that MOMAF pay much attention to the permit right market and its transactions.

To develop an blue tourism website(BTW) for electronic commerce(EC), information requirements of BTW are defined firstly. We defined information requirements of BTW from two aspects, i.e., front office and back office. Information requirements for front office were derived by consumer purchasing decision process. And information requirements for back office were derived by tourism value chain. Total 29 functions are identified as critical EC related functions of BTW. Among them, 25 functions were investigated into BTW. BTWs were searched by search engines - Yahoo and Empas - to Korean websites. There are 12 specialized BTWs, except one cyber museum website. For 12 websites, 25 functions were probed. By the results, in need recognition stage of blue tourism, only weather information was provided in most websites. In information search stage of blue tourism, package recommendation and various contents were provided in most websites. In consumption stage of blue tourism, traffic information were provided in most websites. And in after - sales service stage of blue tourism, bulletin board function was implemented in most websites. The rest of the functions were scarcely implemented. On the whole, it was concluded that most EC related functions of BTW in Korea were not implemented properly. To improve the status quo, it is expected in the dimension of individual website, that marketing planning, customized service, intelligent service, reinforcing purchasing assistance functions, customer relationship management, and escrow service etc. need to be implemented. And it is expected in the dimension of blue tourism industry, that standardizing product catalog, security assistance policy, information sharing by industrial database, finding referral model of BTW, elevating information mind, revising related laws etc. are needed.

본 연구는 온라인 사회연결망서비스(SNS)를 기반으로 하는 전자상거래, 즉 소셜 커머스 상의 콘텐츠 또는 상품광고에 대하여 형성되는 사용자 평판 형성의 신뢰도를 강화시키는 기법을 도출하고자 하는 데에 목적을 두고 있다. 온라인 평판정보는 소비자들의 의사결정에 중요한 요인으로 작용하고 있음에도 불구하고 평가자의 주관적 성향에 의존적이고 또한 이러한 평가를 자신 또는 판매자의 이익을 위해 악용하는 경우가 있기 때문에 온라인 여론 형성의 신뢰도에 문제가 있을 수 있다. 따라서, 본 연구에서는 협업필터링 기법을 기반으로 각 사용자 평판에 차별적인 가중치를 부여하는 방식을 적용해 SNS용 온라인 평판시스템 신뢰도를 향상시키고자 하였다. 본 연구의 결과는 사용자 평가 값에 각 개인의 신뢰도 가중치를 반영함으로써 좀 더 신뢰할 수 있는 평판결과를 제시할 수 있고, 아울러 특정집단의 이익을 위해 사용자 평판시스템을 악용하는 것을 막는 데 기여할 수 있을 것으로 기대된다.

연관분석에 의한 연관규칙은 상품 간 연관성을 나타내고 있으며, 교차판매와 상품진열 등의 마케팅 전략에 활용되고 있다. 그러나, 교차판매 효과를 반영하는 더 실질적인 상품가치를 평가한다면, 상품구색과 이윤극대화 등의 기업 의사결정에 더 유용하게 활용될 수 있을 것이다. 본 연구는 단일상품 간의 연관망과 상품군 간의 연관망 기반에서 상품의 순수가치, 이득가치, 손실가치로 구성되는 유효가치를 바탕으로 상품의 가치를 평가하는 수학적 모형을 제시하고, 두 모형에 대해 각각 예시를 통한 평가과정을 기술하였다. 이 경우, 상품군은 단일상품을 포함하기 때문에 상품군 간 연관망 기반에서의 상품가치 평가모형은 단일상품 기반의 평가모형을 포함하고 있다. 모형의 실질적인 유용성을 보이기 위하여, 국내 한 온라인 쇼핑몰의 과거 1년 간 의류 관련 거래데이터 표본을 이용하여 상품분류군 간의 연관규칙을 발견하고 상품분류별 유효가치를 평가하는 실험을 하였다. 표본은 총 106개 상품분류와 48,044건의 거래 데이터로 이루어져 있다. 먼저, SPSS Clementine 12.0을 이용하여 상품분류군 간 18개의 연관규칙을 발견하였다. 한편, 순수가치와 연관규칙을 바탕으로 이득가치, 손실가치를 계산하고 유효가치를 평가하는 JAVA 어플리케이션을 구현하였다. 유효가치 평가의 실험결과, 순수가치보다 큰 유효가치를 갖는 상품분류가 있는 반면, 순수가치 보다 작은 유효가치를 갖는 상품분류를 확인하였다. 본 연구는 상품 연관망에서 일차적인 관계만을 고려한 유효가치를 평가하였다. 향후, 다단계 연관성의 교차판매 효과를 반영하는 고차적인 평가모형 연구는 보다 효과적인 유효가치 평가를 가능케할 것이다.

The horticultural seed industry has made great progress in the last fifty years of its history after the independence of this country. The industry has accomplished self-sufficiency in major vegetable seeds and has even gained international competitive edge in certain crop seeds, particularly in hybrid cultivar development. However, the industry is facing a crisis at present coming from excessive competition among the domestic seed companies as well as the foreign currency crisis of the country. Several major seed companies have already been acquired by multinational corporations. Many people in the country as well as agriculturists are concerned about this situation. Although it is true that the industry is undergoing hard times, this crisis can be turned into a chance for making new progress depending on the joint efforts of the groups responsible, i.e., private companies, public institutions, and policy makers. Therefore, we have to turn this crisis into an opportunity for self-reform and progress. We should not be discouraged or give up. We Propose some ideas for the Progress of the seed industry. Public institutions and policy makers should do such things in cooperation as 1) training human resources for future breeders, 2) securing a wide range of genetic resources and improvement of the management system, 3) basic science research including biotechnology, 4) releasing breeding stocks from germplasm enhancement through use of exotic accessions, 5) support for breeding region- or use-specific cultivars, and 6) collection of foreign agricultural information for breeding cultivars for overseas markets. Eventually the responsible group for the final development of commercial cultivars, production, sales and management is private companies. Therefore, private companies also should have to do their best to develop competitive cultivars with a missionary spirit and endeavor for both domestic and overseas markets in cooperation with public institutions. Management based on competition, professionalism and rationalism is also urged. We are going to conclude with optimism that we can make a new vault of progress once the private and public sectors closely cooperate for the development of Korean horticultural seed industry by overcoming this crisis.
