This study analysed impact of service quality on customer satisfaction and loyalty in the take-out coffee shop. The switching barrier was also studied as a moderating effect. Particularly, this study focused on relationships between customer loyalty and switching barriers. A lot of previous studies interest only in customers satisfaction. This study also analysed relationships among service quality, customer satisfaction, switching barriers and brand loyalty. Eventually, service quality significantly affects customer satisfaction, moderating effects, brand loyalty and marketing performance. SERVQUAL model which was established by PZB (1988) was used as a service quality factors. The impact on customer satisfaction was analysed using multiple regression analysis. Simple regression analysis was used to find effects of customer satisfaction and customer loyalty. Additional factors of switching barriers was classified based on previous studies. Hierarchical multiple regression analysis was used to find factors of customer loyalty among switching barriers. In the result, we can find that the importance of tangibles, responsiveness in service quality factors and contract cost, search cost and continuous cost in moderating effects.

This study is to in-depth analysis of the copyright issues related to the library's e-book service, which is the cause of the recent conflict between the publishing industry and the library industry. To this end, the purpose and outline of the copyright system were briefly summarized. Then, the jurisprudence of the Copyright Act applied to the borrowing of paper books and e-books was analyzed, and the position of the publisher's association and the library industry were reviewed together. In addition, problems of the current copyright act related to e-book services were diagnosed and directions for improvement were sought. Unlike in the case of paper books, first sale doctrine does not apply to e-book borrowing, so the library cannot acquire the right to service just by purchasing e-books. Based on the contract signed with the distributor in the process of purchasing the e-book, the library acquires the right to service the e-book. However, if the validity period of the exclusive publication right expires, the contract itself becomes invalid, which can cause serious problems in the stability of library services and preservation of resources. In order to solve this problem, it is suggested that the first sale doctrine needs to be extended to digital works.

In recent years, increasing attention has been paid on how to manage a successful relationships between the receiver and provider of the Information Systems(IS) outsourcing services. This study explores the sources of influence for successful outsourcing relationships. Based on the Jaworski's control combination model for marketing, we (1) propose a management combination model of outsourcing relationships where trust is introduced as an intervening variable and outsourcing compleyity as a moderating variable, (2) test this model using a sample of 94 outsourcing projects in 36 organizations that have outsourced there IS functions to external service providers. The results indicated several significant findings. First, the deployment of management mechanism such as contract mechanism and trust building has a significant effect on the outsourcing success through trust only. Second, complexity of outsourcing activities has a moderating effect on relationship management combinations.

기존의 학력인증 서비스는 학교에 직접 방문하거나, 온라인을 통해 종이 증명서를 발급받는다. 하지만 학력인증을 블록체인에 기록하여, 인증 서비스의 비용을 줄이고 절차를 간소화하고자 한다. 더불어, 디지털 증명서를 블록체인에 등록하여 발급해온 증명서의 진위 여부를 확인하는 체제가 잘 갖춰지지 않은 곳에서도 재확인이 필요 없는 서비스를 제공하고자 한다. 블록체인에 증명서를 등록하는 중요한 기능은 '스마트 컨트랙트'를 통해 이루어진다. 매년 졸업요건이 변경된다는 점을 고려하면 스마트 컨트랙트에서 블록체인에 학력인증이 등록되는 조건의 업데이트는 필수불가결이다. 하지만 새로운 스마트 컨트랙트를 배포하는 식의 컨트랙트 업데이트는 여러 문제점들이 있다. 이를 해결하고자 본 논문에서는 proxy contract를 이용한 학력인증 서비스 시스템의 설계를 다루고자 한다.

The BTL (Build-Transfer-Lease) contract of construction project serves as a part for early establishment of industrial foundation for social overhead capital. However, project cost of BTL contract is focused on initial construction cost. Accordingly, operation cost is lowly evaluated because there is no standard criterion for estimating maintenance cost for the facility. The low operation cost can be a factor that reduces service quality of facility operation. This study suggests a resonable method for estimating cost and manpower in the operation phase by using the existing practical data for wastewater treatment plant by BTL contract. The results of the study can be used for evaluating rough operation cost and manpower of similar plant project by facility size.

This study was conducted to identify dietitians' position and role by assessing the present condition on management of human resources in contracted foodservice management company. Questionnaires were distributed to 79 contracted companies (eight large-size, 48 mid-size, 23 small-size companies) from March to May in 2002. Statistical analysis was performed with SPSSwin (version 8.0). The data were analyzed in group comparisons using frequencies and percentage for every item in the questionnaires, $x^2$-test, and oneway ANOVA. About eighty-five percent of contracted foodservice companies employed the new dietitians as full time employees, and seventy-five percent of them were promoted the dietitians by evaluation after a given period of time. As a starting payment for university graduates, large-size companies payed an average of 16,260,000 won/year, which was significantly higher (p<0.01) than those of mid-sized (11,320,000 won/year) and small-sized companies (11,620,000 won/year). The mean lengths of dietitians' service were 33.5 months in large-size companies, 26.5 months in mid-sized companies, 26.0 months in small-sized companies. It was less than 3 years in all companies (avg. 26.9 months). Fifty-four companies (68.4%) employed dietitians in each foodservice contract, whereas 25 companies didn't employ dietitians. The ratios of dietitians out of employees in each department of the companies were 42.6% in the department of contracted foodservice management, 19.9% in the department of menu development, 18.1% in the department of food safety, 8.7% in the department of distribution and purchase, 4.2% in the department of business, and 3.9% in the department of customer satisfaction. The dietitians' positions were directors in two companies (2.5%), general managers in two companies (2.5%), deputy managers in seven companies (8.9%), managers in twenty-nine companies (36.7%), assistant managers/chief clerks in twenty-four companies (30.4%), and chiefs in twenty-five companies (31.6%). The frequencies of training for dietitians were 6.2 times/year for the food safety training, 5.8 times/year for the cooking training, 4.8 times/year for nutrition-related training, and 4.7 times/year for service training.
