Since the introduction of the OA transformative agreement as a new way of licensing electronic resources, the number of OA transformative agreements has continued to grow. Despite the wide range of content that should be included in the agreement due to the nature of the OA transformative agreement, there is a lack of research on OA transformative agreements. As a basis for developing a standard for OA transformative agreements, this study examines the current status of OA transformative agreements and analyzes the differences between two types of OA transformative agreements and the subscription contract. It was found that the number of OA transformative agreements has increased significantly worldwide, but the disclosure of OA transformative agreements has not been universalized. The overall structure of two different types of OA transformative agreements and a subscription contract is similar, but there are differences in the detailed clauses. In the OA transformative agreement, the detailed clauses related to the characteristic of the transformative agreement were newly created, or the details of the transformative agreement were added to the existing clauses of the subscription agreement. There were also some differences between the two types of agreements, identifying clauses that differed in content regardless of the OA transformative agreement. The study concluded that it is important to standardize the OA transformative agreement, as the number of different clauses between agreement types may increase the burden on librarians. This study is significant in that it provides a basis for the development of standardized agreements by examining the overall status of OA transformative agreements and analyzing actual agreements.

In this paper, we propose a multicast routing protocol for the seamless delivery of multicast data to mobile hosts through the optimal route in IP based mobile networks. The proposed multicast routing protocol is a hybrid method employing the merits of the bi-directional tunneling and the remote subscription by considering the mobility of mobile hosts. The proposed protocol satisfies the bound of end-to-end delay and supports the seamless handoff. The simulation results show that the proposed protocol has better performance in the number of multicast tree reconstruction and tunneling length and packet loss time than the previous protocols.

전자저널의 컨텐츠는 출판사의 서버에 디지털파일로 축적되어있으므로 출판사의 사정에 따라 또는 자관의 구독취소 결정에 따라 접속이 중단되는 사태가 발생할 경우 종전의 전자저널 구독분까지 이용할 수 없어 결과적으로 장서가 소실되는 결과를 가져오게 된다. 일부 출판사에서는 과월호 컨텐츠를 수록한 CD를 제공하여 이를 보완하고는 있으나 소장매체의 수명이 한시적일 뿐더러 출판사에서 계속해서 상당한 비용이 소요되는 과월호 컨텐츠 보존을 수행할 지 또한 의문이다. 이 연구는 선진 외국의 사례를 바탕으로 전자저널 컨텐츠의 영구보존에 관한 국내 도서관의 적절한 대처방안을 모색하고자 하였다.

The purpose of this study is to understand the nature of curation commerce in the environment of e-commerce in recent years rapidly changing and looking for ways to take advantage of it. Like the recent trend curation and subscription commerce has been in the limelight in a new way of e-commerce. However, not having appropriately adapted to the market, it has gone out of business or been changing the properties. In analyzing the specific characteristics of the migration queue commerce, it evaluated whether those characteristics do change through the mediating effect of the impact of satisfaction on purchase. This study was carried out using a structured questionnaire, by collecting the material for the 305 general public in the country and it was analyzed using stepwise regression method. After validating the hypothesis, 5 characteristics of curation commerce turned out to have a significant positive effect (+) on purchase and satisfaction of consumers using curation commerce to have a positive effect (+) on purchase. After organizing these findings and discussing the theoretical and practical implications, the direction for future research was proposed.

Many publishers tried flipping, or extensively changed their journals flipped. They considered that converting an established journal into OA journal is more attractive than launching an entirely new OA journal. After conducting a careful literature review, this study provided the background and current situations on flipping. There are flipped OA journals alive published by commercial publisher, society, university, and institute in the field of science and medicine. This study found the increased number of published articles after flipping, with 69% of 97 flipped OA journals in 2015 having impact factors. Also 92% of the journals experienced rising in ranking of impart factor, or achieved it for the first time. It was suggested that the roles of academic society, funding agencies, and universities when it comes to active flipping.

I would like to trace back periodic social trend by searching if regular performance might have reflected on social trend on its theme by analyzing theme trend of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do and to provide the meaningful results for further study by checking if the theme of dancing performance is in relation with social structure. To perform this research, I had studied on previous thesis and reference books. For example, I selected three groups, of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do, to research their theme of regular performance through checking previous thesis related to, performance material, news articles, pamphlets from beginning to present. How to analyze is being proceeded from foundation of dancing company to present according to Kim Byungseok's classification method, which was consistently used for searching theme trend from previous study as below; 1) Theme based on traditional conscious,2) Theme based on Literature, 3) Theme based on Historic issues, 4) Theme based on abstract, 5) Theme based on reality, 6)Theme based on social issues.

The purposes of this study are to compare and analyze the evaluation indicators for selection of journal suggested by scholars and organizations and to prepare theoretical background for the ideal model to meet opposing paradigms of collection management in academic libraries. A web survey method was employed to investigate applications of various selection criteria (27 for printed and 37 for electronic academic Journal) from the top 40 academic libraries in Korea. In addition, data were analysed statistically using factor analysis, t-test, Analysis of Variance(ANOVA), and Spearman's Rank Oder Correlation. The mean ranking for 9 evaluation indicators for printed were as follows: subscribing volumes per departments, degree of use, selection authority, electronic/print bundle, ISI impact factor, Internationality and reputation, costs for subscription, ILL ＆ DDS, space considerations for printed materials. But, 11 evaluation indicators for electronic were as follows : costs for subscription, accessibility, electronic/print bundle, consortia, selection authority, access expandability, subscribing volumes per departments, scholarly features of the university, ISI impact factor, ILL ＆ DDS, internationality and reputations.

Mobile multicast schemes are classified into remote subscription and bi-directional tunneling. While the former scheme has much overhead in the maintenances of multicast tree, the latter suffers from inefficient routing. In this paper, we propose dynamic mobile multicast routing (DMMR) scheme, which is operated on the basis of cost functions related with forwarding cost and tree reconstruction cost, Basically DMMR intends to find lower cost between forwarding cost and tree reconstruction cost. Forwarding cost is the cost of tunneling multicast packets from home agent, and tree reconstruction cost is the joining cost of foreign agent to multicast group. In the case that a mobile host moves to the other area, its foreign agent calculates cost functions related with forwarding cost and tree reconstruction cost. If forwarding cost is higher than tree reconstruction cost, foreign agent joins to multicast group and reconstructs the multicast tree. Accordingly, foreign agent can dynamically adapt remote subscription or bi-directional tunneling, Our scheme provides more stable multicast service to the mobile hosts regardless of the movements of mobile host and the number of mobile group members.

Paid membership is a useful marketing method that can acquire long-term customers. This study benchmarked representative overseas memberships, Amazon Prime, Alibaba 88 Membership, and Rakuten Super Point, so that domestic shopping platform companies can refer to launch the paid membership. The membership services have in common: economic benefits, convenient experiences, and discriminatory treatment. Domestic companies should set the core customer value they want to deliver to consumers and organize the benefits so that paid membership can be operated from a long-term perspective. This study has a high practical contribution and it is necessary to conduct an empirical analysis of experts and a customer user survey in the future.
