China has gone through rapid economic growth due to transitional economies since 1978. In particular, Chinese transitional economies has led to fundamental changes in firms' activities under the socialist system. Nevertheless, Chinese firms have formed new industrial production organizations and spatial orders by sustaining personal networks based on existing traditional firm practice, which is called 'guanxi'. Therefore, the main purpose of this research is to identify the influence of personal networks, guanxi, on the business activities of Chinese firms by investigating the formation of guanxi mechanism. The main characteristics of guanxi represented in inter-firm relations are as follows. First, guanxi has played a role in facilitating inter-firm relations and business activities, because it has an inter-debt relations based on inter-reciprocal relations between firms. Second, Chinese firms has depended on posteriori guanxi rather than inherent guanxi by the internalization of personal networks through 'guanxi communicators'.Third, guanxi between firms and local government in extra-firm relations has been established to minimize risks from unstable legal regulations.

China has transformed her strategies for economic development from exogenous development founded on foreign capitals to endogenous development based on enhancing technology innovation capabilities since 2000. More specifically, Chinese business activities have coupled with new institutional settings which enable them to facilitate advanced technology and management methods. As a result, the characteristics of the spatial economy in China are likely to transfer from export-led developmental space to technology-oriented developmental space. In this context, this paper aims to identify the characteristics of technology-oriented space by investigating intra-, inter- and extra-firms relations of Korean FDI firms in Shanghai, China. In terms of intra-firm relations, Korean FDI firms adopted strategies for maximizing business efficiency and effectiveness by transforming their personal networks into formal networks. In terms of inter-firm relations, the distinction of Korean FDI firms' networks has been found in accordance with firm size, industrial sectors, ways of investment etc. Finally, Korean FDI firms has formal networks resulted from institutional involvement, as well as informal (personal) networks based on guanxi (inter-personal relations) in extra-firm relations. Therefore, two types of processes affecting the networks and institutional legacies of the Soviet system can be identified. First is the interaction of institutions and restructuring of pre-existing networks. Second is the insulated institutions and endurance of preexisting networks. And these two governance types have created regional economies which are embedded and over-embedded.

The purpose of this study is figure out secondary education undergraduates' communication patterns and perceptions of use in KAKAOTALK, one of the most frequently used Social Network Service(SNS). The mixed method research was conducted of survey about 86 students and in-depth interview 10 of them. The chief implication of research showed that it has been firstly functioning them to sustain public and private network and to be an universal tool of expression their opinion, idea, themselves, however, they still regard face-to-face communication important. Secondly, they think that KAKAOTALK is a part of their everyday lives and regarded a communication space to freely express themselves and to adjust and manage their image. Thirdly, they psychologically solved their loneliness and were encouraged, moreover, the contents of communication were different according to usd of public or private team chat room. It needs a follow-up study comparatively to analyze other generation's cognitive psychological values in SNS and to suggest digital culture literacy guideline.

우리는 머지않아 서점 대신 디스켓 전시장에서 책을 구입하든지, 아니면 아예 컴퓨터 판매네트워크를 통해 잡지나 책을 받게 될지도 모른다. 우리는 결코 그것을 있을 수 없는 일로 부정할 수는 없다. 그럼에도 불구하고 디스크책이 종이책을 완전히 대치하지는 못할 것이다. 책은 사라지지도, 사라져서도 안될 것이다.

The digital copying and digital transmission are rapidily Increasing with the innovation of information technology and the development of networking technology. But It Is Inevitable to limit copyright for the public benefit and cultural development In the digital environment in like manner with the analog environment. First, this study examinated the international trends and legulations relating to the copyright limitations In the U.S. and Japan for the fair use. Second, it dealed with the problems of the digital copying relating to the temporary storage In RAM and screen display that are recently becoming international issues. Third, it concretely explored and analyzed the problems according to the application of the fall use of the private copying, the library copying, and the copying for the purpose of school education in the network environment. In conclusion, to solve these problems that Is occurred from legulations In the analog environment Is needed the revision of the existing copyright law in Korea. Finally, this study suggested 'the copyright collecive management system' and 'the private copying levy system' as the systemic devices to control the digital private copying.

Guanxi could be regarded as communities based on blood, regionalism, school ties centering on individual person. It has been used as a means of personal interests security and acquisition. What is more, it has formed a mode of socio-economic order, which is an inter-obligation relations based on mutual benefits. In practice, it is necessary to understand and accept guanxi in China, as it is a key factor to understand consumer patterns, inter-firm relations and extra-firm relations between firm and government. In this context, the main aim of the reserach is to identify the impact of guanxi on the business activities of Korean foreign direct investment firms in China by investigating their networks based on guanxi.

Recently, the energy shortage of sensors and the leakage of private information are considered as serious problems as the number of sensors is increasing due to the technological advance in Internet-of-Things. RF energy harvesting, in which sensors collect energy from external RF signals, and physical layer security become increasingly important to solve these problems. In this paper, we propose a time switching-based network analog coding for improving information security in wireless networks where the relay can harvest energy from source signals. We formulate 2-hop relay networks where an eavesdropper tries to overhear source signals, and find an optimal time switching ratio for maximizing the minimum required secrecy capacity using mathematical analysis. Through simulations under various environments, it is shown that the proposed scheme improves the minimum required secrecy capacity significantly, compared to the conventional scheme.

Digital home devices aims at providing the multimedia service which is not limited at time and space in home network environment. However, it is incapable of the fair use of consumers who legally buys contents, and causes damage to the contents providers owing to the indiscriminate distribution and use of illegal contents. DRM system appeared to solve this problem cannot protect the license stored on digital home devices and manage license by redistribution. This paper proposes a license audit model which makes an inspection of illegal access, modification and redistribution and reports alert logs to server.
