The present study purposed to establish a network for building an efficient disaster response system and for this purpose, we compared cases of disaster response in Japan and Korea. In Japan, disasters are responded jointly through the network of the central government, local self governing bodies and non governmental organizations. In Korea, however, the cooperative network among different areas is weak and this is aggravating damages caused by disasters. That is, in Korea, disaster response services have been mainly carried out by the public sector. The public sector can operate a powerful disaster management system using its extensive management resources, compelling power, and legal authorities. However, it was found that, due to the characteristics of contemporary society, efforts by the public sector including the central government and the local self government bodies have limitations in managing disasters effectively. Thus, for efficient disaster response in Korea, it is urgently required to establish a national disaster response network as well as a private sector cooperation system and to induce NGOs to participate in the disaster response system through institutional devices.

최근 저전력의 무선통신과 적응형 자가조직(Self-organization)능력을 가진 초소형 마이크로센서의 하드웨어 기술 발전으로 다양한 기능의 센서를 이용한 무선 센서 네트워크의 구축이 가능하게 되었다. 무선 센서 네트워크는 현실세계의 여러 이벤트를 감지하는 센싱 작업을 기반으로 주로 과학용이나 군사용으로 많이 사용되고있다. 즉, 직접 접근이 용이하지 않은 전장에서의 적군감시, 열악한 환경을 모니터링 하는 지진감지, 교통의 감시와 제어를 위한 지능형 교통통제, 장기간의 관찰이 요구되는 생태감시 등 그 응용범위가 다양하게 확장되고 있다.

This study aimed to investigate the effect of firefighters' social capital on subjective happiness. This research was conducted from Jun 12 to Aug 25, 2017, and a descriptive analysis, t-test, hierarchical regression analysis was carried out based on the results of a survey with 351 firefighters in Gyeonggi-do to verify the research hypothesis. As a result, it was revealed that network(${\beta}=.315$, p<.001), trust(${\beta}=.293$, p<.01), cooperation(${\beta}=.225$, p<.01) and trust among other sub-variables of firefighters' social capital had significant effects on subjective happiness. Based on the results, this research suggested that various measures to strengthen social capital would be required in order to improve fire-fighters' happiness: efforts to increase trust within the organization, political support for vitalizing formal network as a communication channel among firefighters organizations, encouraging interest in the community and promoting informal network such as volunteer work, developing transparency in operating the organizational policy and system, etc.

In this study, we explore the characteristics of directors' network structure and investigate the relationship among the network of board directors in the Korean logistics industry. Social network analysis reveals hidden patterns of the interlocking directors' network. We construct a directors' network index using social network analysis of the Korean logistics industry. Empirical results have showed that of the 23 companies analyzed, the network index of Korean Air is the highest. The interlocking network index of Korean Air, Hanjin and Hanjin Logistics Company is 0.4, 0.32 and 0.24 respectively. Korean Air has a strong central interlocking network that can create social power through the logistics industry. Our paper contributes to the broad literature in two ways. First, unlike the existing literature on director structure, this paper concentrates on the relationship among interlocking directors. Second, logistics firms need to be aware of the importance of networks and recognize the occurrence of power.

This study analyses interorganizational innovation networks empirically in the Korean biotechnology industry, based on systems of innovation approach. Empirical findings of this study are as follows. Innovation networks have not been well developed in the Korean biotechnology industry. Main agents who participate in innovation networks are workers at venture firms, university professors, researchers at government-sponsored research institutions. They all recognize the positive effects of innovation networks. The enhancement of participation willingness and competency of agents, the enrichment of trust and control among agents, and the effective acquisition of the useful technology and resources in innovation networks will largely contribute to development of innovation networks in the Korean biotechnology industry.

본 논문에서는 기존의 TCP/IP 환경에 새로운 프로토콜을 적용하여 외부의 해킹으로부터 보다 안전한 형태의 다중 시스템을 설계하고 이를 이용한 강력한 인증시스템을 제안한다. 기존 네트워크 보안이 차세대 네트워크에 미치는 영향에 대한 연구의 필요성도 매우 높아지고 있다. 또한 IP 주소 기반의 서비스 운용으로, 대형 다수의 통신요구에 대해 서비스 불가 문제점 보유, 최근 대형 통신사 중심으로 탈 TCP/IP 연구가 활발히 진행 중으로 현재 인터넷의 표준으로 사용되고 있는 TCP/IP 프로토콜이 원초적으로 보안에 대한 취약한 문제점 보유하고 있어 이를 해결하기 위한 방안 연구 진행 중에 차세대 네트워크를 활용하여 보다 효율적이고 원활한 서비스 활용 및 기존 TCP/IP가 보유한 근본적인 문제점으로 인해 발생하고 있는 해킹에 대한 방지 방안 모색 필요하다. 따라서 본 논문에서는 조직 및 법·제도 관점에서 효율적인 네트워크 체계의 SW 관리 차원의 발전방향을 제시하기 위해 국내외에서 진행되고 있는 차세대 네트워크의 SW 관리 체계의 현황조사 및 문제점 도출하며 이를 보다 안정하게 활용할 수 있는 새로운 형태의 네트워크를 설계하고 제안하는 것을 나타낸다.

To sense a wide area with mobile nodes, the uniformity of node deployment is a very important issue. In this paper, we consider the coverage problem to sense big data in sparse mobile ad hoc networks. In most existing works on the coverage problem, it has been assumed that the number of nodes is large enough to cover the area in the network. However, the coverage problem in sparse mobile ad hoc networks differs in the sense that a long-distance between nodes should be formed to avoid the overlapping coverage areas. We formulate the sensor coverage problem in sparse mobile ad hoc networks and provide the solution to the problem by a self-organized approach without a central authority. The experimental results show that our approach is more efficient than the existing ones, subject to both of coverage areas and energy consumption.

Korea government has established 67 agri-food clusters for 10 years. In recent years, the criticism of this policy has significantly increased due to trials and errors. The purpose of this study is to suggest some policy implications for the focal firm and governance mechanism through the case study of Muan Loess Sweet Potato Cluster. The concept of netchain was used as an analysis framework. Muan Loess Sweet Potato Cluster doesn't operate an integrated production organization and focal firm doesn't exercise its influence as well. The cluster agency, focal firm of Cluster, is important for a Agri-food Cluster to grow continuously. it must have a great influence on organizing networks and an enough capacity for forming coordination mechanism. Also, Local governments must actively be involved in the network formation and coordination and inform the vision and plan for development.

The purpose of this study is to examine the factors influencing performance of internal, external environment and entrepreneurship in the social enterprise with network activity. This model tests various theoretical research hypotheses relating to performance of social enterprise, internal, external environment, entrepreneurship and network activity. The proposed model is analyzed to target social entrepreneurs. The results of hypothesis testing are as follows. First, organizational culture positively influence entrepreneurship. Second, environmental uncertainty positively influence entrepreneurship. Third, entrepreneurship positively influence managerial and social performance. Finally, organizational culture to entrepreneurship for high group of network activity is significantly larger than those for low group of network activity. In addition, environmental uncertainty to entrepreneurship for low group of network activity is significantly larger than those for high group of network activity.
