As the 4th Industrial Revolution unfolds rapidly, it is important to re-light the intrinsic mission given to universities from a system theory perspective as a condition for the university to survive. In this study, the university was prescribed as a fifth service industry that creates high value-added through higher education services, and attempted to provide a new and novel perspective to various university officials for the scientific rationalization of university management by re-describing it based on the Multidisciplinary perspective based on business administration, but in particular on the theory of service operation management. To this end, the primary purpose of this study is to classify the nature of educational organizations, research organizations, service organizations, and support organizations to properly perform the university's essential mission of education, research, and service, and to explore concepts and techniques for performing management activities that are appropriate to them. In addition, after identifying the university from an academic and practical point of view as a fifth service industry that creates high value-added through higher education services, but more specifically, to provide a new perspective and means for the scientific rationalization of university management by re-identifying university administration based on the business administration theory, in particular the theory of service operation management, and further reflecting a recent trend to view the university president from the CEO's point of view, the specific purpose of this study is to look at this academic system. Through this, we sought the ideal form of a systematic and scientific university management organization that can respond to new environmental changes.

It is necessary to examine the service R&D revitalization plan by establishing service R&D hub researching the service R&D because a shortage of facility and infrastructure makes impossible to turn ideas into products (service). This research aims at establishing the implementation plan of service R&D hub that invigorates local service industries and contributes to carry out the plan. Service R&D hub is a focal point of service R&D activities which inter-connects service R&D activities distributed across ministries of central government and fields of studies, and which invigorates service R&D activities and enhances competitive power of service industries in Korea. It is necessary to establish main hub like Service Engineering Research Center in Japan and Fraunhofer IAO in Germany which take the lead in national service R&D activities, and make it build the solid foundation of service R&D activities in public sector and also create service innovation ecosystem. Considering the interdisciplinary characters of service R&D, it is essential to establish additional sub-hubs to meet a variety of demands of service R&D. It is also necessary to establish 'Living Lab', an open innovation system, which connects research institutions, universities, and corporates to make them target the specific fields of their own, and enhance open R&D and innovation in service industries.

Throughout the world, rotavirus infections cause extensive morbidity in human infants and diarrhea in animals such as white scour caused by bovine rotavirus in calves. We isolated three rotavirus strains designated KV0407, KV0418, and KV0426 from 103 fecal samples of diarrheic calves. The genes coding for proteins VP4, VP6, VP7, and NSP4 from strain KV0407 were sequenced and compared with the nucleotide sequences of other known strains of rotavirus. The KV0407 VP4 gene was highly homologous to the OSU (99.4%) and JL94 (99.4%), but not the B223 (62.4%) and K33 (62.4%) VP4 genes. The KV0407 and KV0418 VP7 genes were most similar to the OSU and super-short type VMRI VP7 genes. Based on nucleotide sequence analysis, the KV0407 strain was tentatively assigned to A serogroup (SG I), G5P[7], NSP4 genotype B and the KV0418 and KV0426 strains were assigned to A serogroup (SG I), G6P[5], NSP4 genotype A. The genetic characterization of these bovine rotavirus isolates could be useful for the diagnosis and prevention of diarrhea in calves.

We propose ID-exchange protocol for Connectionless Location-Awareness Service (CLAS) to locate mobile nodes in indoor sensor network. When adapting location-awareness service to sensor network, the target system must be designed in accordance with various metrics which reflect the system requirement. We especially consider sustainability of the existing service which has been provided for its original purpose, such as environmental monitoring. The detailed meaning of sustainability here is that, even if location-awareness service is newly added to the existing service, the system must be assured to retain a stable network condition, and to deal with newly caused traffic properly. The CLAS ID-exchange protocol is especially designed for fixture and mobile nodes communication to achieve these properties. The protocol operates on 802.15.4 MAC layer to make mobile node work independently of the procedure to build routing table of fixture node, so a stable routing condition can be achieved even if there are many mobile nodes. Moreover, the dedicated frequency channel is assigned only for this protocol, so that traffic caused by location-awareness service can be distributed to another channel. A real system adapting the protocol was implemented to monitor fire and authorities' positions. We verified the overhead and elapsed time for location-awareness. The result shows the proposed protocol has a high performance in detecting speed, traffic distribution, and stability of overall network.

Purpose - International diversification, a critical issue in research and practice, undoubtedly represents a growth strategy with great potential impact on firm performance. Although the literature has widely examined the relationship between international diversification and firm performance in international business and strategic management research, it remains unconfirmed. This study, therefore, aims to clarify the relationship as it relates to information service firms. Research design, data and methodology - To examine the international diversification-performance relationship, this study uses a sample of major Korean service firms spread over four industries spanning a period of five years between 2005 and 2009. In this study. generalized least square was used to analyze the relationship between international diversification and performance of service firms. Result - The result showed the U-shaped curvilinear form between international diversification and performance in service firms. Especially, IT service firms may differ from other service firms that the negative effect of internationality may have weaker than other types of service firm. Conclusion - Based on the empirical results, the U-shape relationship between international diversification and performance is confirmed in Korea service firms. Furthermore, information service firm may reduce the initial internationalization cost by transferring codified and digitized information using information and communication technology, so that gain benefit from early international expansion.
