ICT technology development has led to a breakthrough change in government decision making by improving mutual communication between various stakeholders. The formation of ICT-based cooperation network between public organizations and civic tech developers to solve the problem of masks in the COVID-19 pandemic serves as a milestone. The purpose of this study is to examine the properties of e-Governance and analyze the dynamic network structure of the communication process for chat rooms created during the development of public mask apps. First, as a result of the analysis, the possibility of online-based e-Governance can be identified. In addition, the combination of expertise to solve social problems interacted organically within the network. Emotional communication for cooperation between key actors was marked as important for the successful operation of the network.

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.

클라우드 컴퓨팅 서비스는 클라우드 서비스 고객에게 편리하면서도 온디맨드 (on-demand) 방식으로 풀 형태로 준비되어 있는 공유 자원 (네트워크, 서버, 메모리, 어플리케이션, 그리고 서비스) 을 제공한다. 클라우드 컴퓨팅 서비스의 확산을 위해서 가장 우려되는 것은 보안 위협과 클라우드 서비스 고객의 정보 통제권 상실과 개인정보 유출 등의 프라이버시 이슈이다. 클라우드 컴퓨팅 보안을 위한 국제 표준화 활동은 두 개의 공적 표준화 기구인 국제전기통신연합-전기통신표준화부문 연구반 17 (ITU-T SG 17) [1]과 국제표준화기구/국제전기표준화위원회 합동기술위원회 1 연구그룹 27(ISO/IEC JTC 1/SC 27) [3] 에서 주로 수행되고 있다. 본 논문에서는 클라우드 컴퓨팅 보안을 위해 양대 공적 국제 표준화 기구에서 추진 중인 동향을 제시하고, 이를 근거로 향후 표준화 추진 방향을 제시하고자 한다.

영상 보안 시스템은 다양한 영역에서 그 중요성이 부각되고 있으며 보통 공적 공간 및 사적인 환경에 사용되므로, 민감한 정보나 개인 정보에 접근하거나 정보의 조작에 대한 우려가 높아지고 있다. 최근 영상 보안시스템은 분산 스마트 카메라로 발전하고 있으며 이들의 보안 문제는 네트워크 임베디드 시스템 및 센서 네트워크의 경우와 유사한 점이 있지만 개인 정보 보호 및 실시간 동작 등 스마트 카메라 네트워크만의 특별한 요구도 있다. 이러한 영상 보안 시스템의 보안 문제는 전체적인 시스템 구조의 설계에서부터 보안과 개인정보보호 이슈를 고려해하여야만 이러한 문제들을 해결할 수 있다. 본 논문에서는 현재의 영상 보안 시스템의 보안 및 개인 정보 보호 문제를 다룬다. 영상 보안 시스템의 일반적인 보안위험, 노드에서 문제를 분석하고 네트워크 수준에서 사용 가능한 솔루션을 제시하고 보안 요구 사항, 가능한 공격을 설명한다.

This paper was studied in export policy Revitalization of SMEs mainly in various countries of Indochina, especially in Laos, which is emerging as a new market after China. Laos is a socialist country, but in 2014, led by the current active open-door policy, education, social, cultural and people-to-people exchanges are going briskly, light industry and the expansion of social infrastructure such as laying the foundation for economic development. This paper presents a plan to dominate the emerging frontier markets are public enterprises and government agencies that do not respond quickly. Already pioneered by building a network in local development staff for this purpose, such as volunteers, missionaries, professors and configure the network of exploitation and human development personnel look for Revitalization of SMEs in urban and regional growth.

This study attempted to study the relation between the social capitals and self esteem, psychological wellbeing of the elderly. This study took a questionnaire survey to 162 elderly persons over 65 years old in Busan Metropolitan City. The results of the impact of social capitals upon mental health of the elderly were as follows. For the social capitals and self esteem, formal reliability, formal network and the norm, women had significantly positive(+) impact on self esteem. For the social capitals and psychological wellbeing, formal reliability, women had significantly positive(+) impact on psychological wellbeing, while the norm had significantly negative (-) impact on psychological wellbeing. Based on such results, this study suggested meaning and necessity to construct the social capitals and its activation for the improvement of psychological health of the elderly. Finally, it remarked the limits of the study and the suggestions for the further research direction.

Korean construction engineering firms want to pave the way for expansion of overseas markets through the World Bank's Official Development Assistance (ODA) projects as a way to improve their overseas project performance. However, since the World Bank project competes with global companies for limited projects, building partnerships with suitable business partners is essential to gain an upper hand in bidding competition and meet the institutional conditions of the recipient country. In this regard, many network studies have been conducted in the past through Social Network Analysis (SNA), but few have been analyzed based on the process of changes in the network. So, This study collected winning data from the three Southeast Asian countries that ended after the World Bank's ODA project performed smoothly, and established a learning-based link prediction model that reflected the dynamic nature of the network. As a result, the 11 main variables acting on building a cooperative relationship between winning companies were derived and the effect of each variables on the probability value of cooperation between individual links was identified.

자원 예약을 보장하지 못하는 네트워크 상에서 실시간 멀티미디어 응용의 만족스러운 서비스를 위해서는 효과적인 종단 시스템의 운영이 필요하다. 이러한 운영 기술 중 버퍼를 이용한 응용 프로그램 수준의 대역폭 평활화 기술과 태스크 스케줄링 기법은 핵심적인 부분을 차지한다. 기존에 제안된 온라인 대역폭 평활화 기법은 동적 슬라이딩 윈도우와 공적 버퍼를 이용하여 네트워크에 적응할 뿐만 아니라 요구 대역폭 평활화를 통해 지터를 흡수, 완충시킴으로써 더 나은 서비스 품질을 보장한다. 그러나 응용 프로그램 수준에서 동작하기 때문에 프로그램의 수행 품질보장을 위한 시간 대역을 보장하지 못할 뿐만 아니라 지터의 발생 가능성이 높다. 본 연구에서는 효과적인 버퍼 관리를 통해 서비스 품질의 손실을 최소화하는 적응성 있는 온라인 대역폭 평활화 기법이 안정적으로 동작하기 위한 최적화된 태스크 스케줄링 기법을 제안한다. 먼저 태스크 스케줄링 기법은 멀티미디어 데이터의 생산과 소비를 적시에 보장할 수 있도록 하여 지터의 발생을 최소화하고, 만일 네트워크 지터가 발생하더라도 응용 프로그램 수준의 버퍼 관리를 통해 완충시킴으로서 서비스 품질의 손실을 최소화한다. 모의 실험에서는 제안된 기법이 온라인 대역폭 평활화 기법을 효과적으로 지원함을 보인다.
