This study is aimed at exploring the impact of the characteristics of the firms on firm's networking. We develop a framework theorizing firm's networking according to sales, size, research facility, the percentage of R&D staff to total employees, the percentage of R&D investment to total sales, the number of the certification, the intention of attending seminars, the experience of participating in the government subsidy program. The results of the analysis show that research capacity, openness to a variety of information source, the experience of participating in the government subsidy program are significant in determining the firm's networking. The government needs to encourage the firms to improve their research capacity, and to train the coordinators to help the firms get higher openness to a variety of information source, use the government subsidy program.

It becomes to be essential for firms to build up collaboration ecosystem with diverse entities and to be common for firms to absorb knowledge from external environment for their innovation. Companies try to transfer technological or knowledge asset to other firms through open innovation. The purpose of this research is to suggest the role of universities in University-Industry Collaborations besides research collaboration and we focus on the role of university to strengthen the regional business ecosystem network. For this research, we analyze a specific UIC(University Industry Collaboration) program called as "Business Clinic Day" which provides a consulting service for firms, especially, SMEs with a specific problem by a group of consultants including CEOs, professors, and heads of regional public or private service providers. Then we studied how the business network has changed after the program with network analysis. Also, we try to find out the main pattern of network structure extension of business ecosystem with interview. This study illustrates that changing types of network are formed between university and SMEs by clinic day. The result shows that not only new role as a network promoter, but also the partner as a technology-provider in the regional business ecosystem.

Most Social Network Service (SNS) provide online chat, video and file sharing, blogging and others. Because of this advantage, people depend on SNS to communicate with others. However, recently SNS encourage people to reveal too much information broadly so SNS users are concerned about privacy invasion and data spill. They also feel fatigue in process of touching people they don't know while using SNSs. That is the reason why they attempt to switch from opened SNS to Closed SNS. Therefore, the purpose of this study is to empirically investigate and analyze the effect of the factors on the SNS users' switching behavior when using SNS. To accomplish this purpose, this research adopted "Push-Pull-Mooring (PPM)" framework. The PPM is proposed by population geologist, who used it to explain the incentives of demographic migration. Following PPM model, this research empirically examines the three categories of antecedents for SNS switching intention toward closed SNS: push (i.e., weak connection, privacy concern, relative complexity), pull (i.e., enjoyment, belongingness, peer influence), mooring (i.e., SNS fatigue, user resistance) factors. The survey was conducted for 285 users on SNS communities in Korea. The results of this study are as follows; First, wear connection and privacy concern are significantly related to SNS switching intention. Second, enjoyment and belongingness are significantly related to SNS switching intention. Finally, the results show that SNS fatigue has a moderating effect on the links between push factors and SNS switching Intention. Also, user resistance has a moderating effect on the links between pull factors and SNS switching Intention. These findings contribute to the SNS literature both theoretically and practically.

As Information Security Technology has become rather transparent, wide, and integrated than in part, exclusive, and separated, A necessity of the study about integrating the separated distributed security systems into one module, has grown However, there is no integrated framework which can manage all separate security systems as one integrated one yet. Accordingly, we propose a new policy based network admirustrative model in this paper which can integrate individual security systems and distributed control way into one effectively.

This research investigated to what extent social media use and motivation contributed to the bridging/bonding social capital and social, political participation by using the national survey on high school and university students. In particular, this research divided social media into two groups: open and closed one. The result of analysis showed that the use of open social media reinforced bridging social capital and that of closed social media did bonding social capital. Motives for social media use affected both bridging social capital and bonding social capital. Social media use and motive all had a positive influence on social, political participation. In conclusion, the effect of social media on social capital may be decided by the characteristics of social media and the purpose of social media use.

오늘날 미래인터넷 기술의 하나로서 SDN이 클라우드 서비스, 모바일 서비스, 스마트 TV, 빅데이터 및 사물지능통신 등의 새로운 서비스를 제공할 수 있는 개방형 플랫폼으로 주목받고 있다. 본고에서는 이러한 SDN 망을 구축함에 있어서 제어 인터페이스, QoS, 멀티캐스트, 이동성 및 네트워크 보안 측면에서 고려해야 할 사항들을 살펴본다. 기존 네트워크의 근본적인 문제점으로 인해 발생한 복잡성 및 성능 저하 요인들이 SDN의 장점을 활용하여 해결될 수 있으며, 이에 본고에서 제시된 고려 사항들이 큰 역할을 할 것이다.

A trade logistic informatization system under Open Systems Interconnection(OSI) includes a Port Management Information System, a Maritime Information System, and an Export and Import Batch Processing System. These have made a great contribution in the creation of more convenient and efficient management for the logistics industries in our country. However, this management is exposed to the technological problems of networks due to the explosive use in the sending and receiving of e-documents. For our country to grow as a center for port and logistic information, we should make the best use of the control systems using networks and further advance the export and import logistic systems. Therefore, this study aims to propose management systems for a composite network and an invasion detection system for efficient management of an e-trade network under OSI. Methods to rationalize the internal organizations such as coordination of organizations and human resources according to alloted network functions, commissions and arbitrary decisions, and reorganization of relevant regulations are not discussed here. This study looked at trade network under OSI from the aspect of practical business affairs and presented a basis for further interpretation.

This study is to explore the contents and interaction of residents voluntary network and propose the strategies to promote residents voluntary network. The grounded theory was utilized to attain our object. Total of seven social worker and 17 residents participated in the study. Data were collected through in-depth interviews and documents. The data were analyzed by using Strauss and Corbin's method. Results are the followings. In open coding 13 categories, 32 subcategories and 133 concepts were constructed. In axial coding causal conditions were qualitative ascent of needs, emergence of the right welfare consumer. Phenomenon was agitation of praxis ground and grope of exist. Contextual conditions were crisis resources, skepticism of welfare. Intervention conditions were maturation of welfare cognition and proliferation of the sense of community responsibility. Strategy were resocialization of voluntary organization and construction of field related service delivery system. Consequence were grass routing welfare strategic fitting service system.

문제해결력 및 의사결정능력 향상이라는 교육 목표를 달성하기 위한 대표적인 방법 중 협동학습은 큰 효과를 보인다. 이러한 협동학습은 학습 환경이 변화함에 따라 오프라인 협동학습에서 웹기반 협동학습으로 발전되었고 요즘은 웹2.0 기반의 협동학습까지 등장하고 있다. 그러나 웹2.0의 '참여, 공유, 개방' 개념의 교육적 활용을 높이기 위해서는 무선네트워크 환경이 필수적이다. 따라서 본 연구는 무선네트워크 환경의 웹2.0 기반의 협동학습 전략을 구안하고 적용함으로서 교육적 요구에 맞는 타당성과 효과성을 검증하였다. 또한 본 연구에서 제안하는 학습전략에서 웹2.0을 통한 온라인 학습지원시스템(WCLS) 활용 방안을 제시하고 이를 통해 협동학습의 효과를 높이기 위한 교사의 역할 모형을 제안한다.
