The purpose of the study is to implement the management model of the institutional repositories for the efficient distribution infrastructure of national knowledge focusing on the dCollection system which is operated by KERIS (service provider). In order to build the management model, the two steps were utilized. The first step is to investigate the checklists of repositories that are important factors for the successful repository implementation through literature review. On the other hand, the second one is to survey the current status of the sixteen domestic and foreign institutional repositories through interviews, surveys and email as well as the repository home pages and literature reviews. Through the two steps, the management model including six components such as content and librarian role was proposed. The proposed management model will be utilized to supply guides both to the universities which plan to build their institutional repositories and to the universities which try to promote the activities of their repositories.

A blind video watermarking scheme for providing safety, authenticity, and copyright protection is proposed in this paper, which is robust to MPEG-4 SVC and multimedia transcoding. In proposed method, embedding and detecting of watermark is performed based on base layer with considering spatial SVC. To be robust from temporal SVC, our method embeds repeatedly a permutated character with ordering number per one frame. Also for robustness from multimedia transcoding and FGS, the method is embedded watermark in low middle frequency of each frame adaptively based on DCT in ROI. Through experimental results, invisibility of the watermark is confirmed and robustness of the watermark against the spatial SVC, temporal SVC, FGS and video transcoding between MPEG-2 and MPEG-4 SVC is also verified.

Recently, as the number of Internet of Things users has increased, IETF (Internet Engineering Task Force) has released the CoAP (Constrained Application Protocol). So Internet of Things have been researched actively. However, existing studies are difficult to adapt to streaming service due to low transmission rate that result from buffer underflow. In other words, one block is transmitted one block to client's one request according to the internet environment of limited resources. The proposed scheme adaptively adjusts the rate of CON(Confirmable) message among all messages for predicting the exact network condition. Based on this, the number of blocks is determined by using buffer occupancy rate and content download rate. Therefore it improves the quality of user experience by mitigating playback interruption. Experimental results show that the proposed scheme solves the buffer underflow problem in Internet of Things streaming environment by controlling transmission rate according to the network condition.

A great number of institutions around the world have been building digital repositories to communicate scholarly information. Meanwhile, digital repositories have been struggling with how to preserve increased volume of digital contents for the long term and how to build a sustainable information environment. The HathiTrust partnership was established to meet the need of a sustainable collaborative model of digital repositories in research libraries, mainly in North America, and has been expanded globally by signing with other libraries around the world. This paper is dealt with the establishment, operation and policy, construction status, and user service of the HathiTrust. The results presented in this paper include the benefits and potential opportunities of the HathiTrust as a participating member. Partnership in HathiTrust would allow each member institution to provide more cost-effective operations, shared management and long-term preservation of digital content, ease of copyright management, and increased accessibility. In the future it is expected to provide a shared storage of printed materials and to facilitate a big data research center.

Performing arts is an intangible arts that disappears immediately at the moment it is presented and remains only in the memory of the performer's body and audience. The same repetition, restoration and reproduction of the disappeared performance is impossible, but artists of all times and places have tried various recording methodology to leave their performances in the tangible form. The performing arts archive is where performing arts are recorded, preserved, and utilized. In the fourth industrial Revolution era, library institutions in developed countries are turning into institutions that support creative activity by not only artists but also the general public. Korea's performing arts archives should also shift from the role of an old archive to a platform to create new cultural contents. This paper summarizes the changes in the Korean performing arts archive and presents the creative application of the performing arts archive in response to the fourth industrial revolution.

Since 2010, the universities in Korea have been faced severe difficulties on the selection of students and on the delivery of high quality education services, as the number of students is reduced and the college entrance rate is declined. To solve these problems, the universities have introduced the various and professional education services such as team-based projects, case study, e-learning, action learning, etc. The purpose of this study is to examine the effect of team-based project learning on the student's satisfaction in business education. The 4 factors(team cohesiveness, teamwork, team performance and goal achievement) are measured by using questionnaire survey and data are collected from 134 students(34 teams) for 4 subjects. The results show that the structure of team cohesiveness${\rightarrow}$teamwork${\rightarrow}$student's satisfaction is statistically significant, and that team performance and goal achievement are not significant. The student's satisfaction in team-based project learning would highly be related with team cohesiveness.
