이동 ad-hoc 네트워크는 기반 망의 도움 없이 모바일 노드들로만 구성되어진 임시적인 네트워크이다. ad-hoc 네트워크를 구성한 모바일 노드들은 지속적인 전원공급이 힘들기 때문에 자신의 한정된 에너지에 의존한다. 이러한 모바일 노드의 에너지 소비를 줄이기 위해 IEEE 802.11 PSM를 적용한 다중 홉 ad-hoc 네트워크 모델에 대해서 최근 많은 연구가 이루어졌다. 다중 홉 ad-hoc 네트워크에 802.11 PSM을 적용하면 송수신에 참여하지 않는 모바일 노드들의 에너지소비를 절약하게 되어 네트워크 활동시간을 증가시키게 된다.

This study investigated the carbon offset project activities as the activities of producing commodities by a case study on the Korean Clean Development Mechanism(CDM) industry. This study draw the networks of Korean CDM industry by extracting major agents and surrounding agents and by analyzing the characteristics of the linkages. The project participants owning the CDM projects hires CDM consultancies and designated operational entities(DOEs). The technical knowledge for carbon emission reduction made links between project participants and the CDM project operational knowledge made links between project participants and CDM consultancies. Links between project participants and DOEs are affected by social and geographical proximities. The value of the knowledge for CDM industrial activities determined the role of agents and type of linkages. The agents with the irreplaceable knowledge could be a project conducting firms. The agents without it became outsourcing contractors.

The explosive growth of social networking services based on smart devices popularize these relationships and activities online in accordance with the far larger impact of this on the real life offline, the interest and importance for the online activity is increasing. In this study, factors affecting the SNS activity are defined by object, user, influence direction, influence distance and proposed a method to measure organic terms in effect between the SNS users. Influence Direction and Influence Strength (or Distance) are elaborated by using the existing influence measurement element such as structured data - the number of friends, the difference between the number of contacts - and the new influence measurement element such as unstructured data - gap between the former time and the latter time, preference and type of response behavior - that occur in social network service. In addition, the system for collecting and analysing data for measuring influence from social network service and the process model on the method for measuring influence is tested by using sample data on Facebook and explained the implementation probability.

This paper is a research on the curriculums of network and digital creation tools among SW education in order to apply them to SW curriculum in education fields. For doing so, a curriculum model was developed by extracting main key words through the analyses of domestic and foreign SW curriculum, and reorganization of concept understanding and learning activity elements was made so as to be fit to characteristics of each curriculum. And curriculums were remodeled by curriculum such like concept understanding was focussed in network, activities in digital creation tools and its validity was suggested through expert verification by composing contents elements based on the results. Also, this model was proposed so that each school could recompose it easily by combining contents elements of other curriculums. Therefore, the suggested model could be utilized as a basic research data in applying domestic SW curriculum standard model.

In the face of the prolonged Covid-19, this study conducted a network analysis to propose the policy direction for the Korean National Assembly to go forward. Using COVID-19 news articles, various types of networks were created and analyzed for the parliamentary activities of the Korean National Assembly related to Covid-19. Specifically, we utilize the co-occurrence and keyword information to generate two types of parliamentary networks: co-occurrence-based network and content-based network. In addition, a topic keyword-driven parliamentary network was constructed by using topic modeling. The results of the study are as follows. First, lawmakers in the ruling party had a wide range of topics regarding Covid-19, while lawmakers from other political parties had a limited number of issues covered. Next, a few representative legislators were identified as influential actors in most of the centrality indicators. Based on the research results, cooperation on diverse agendas related to Covid-19 should be promoted between lawmakers from various political parties. And representative legislators from both major parties should play a crucial role as intermediaries to increase communication between them.

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.

정보통신산업은 네트워크산업으로서 다른 산업에 비해 상호운용성 확보라는 목표달성이 매우 중요시되고 있으며 이를 위해 국내뿐만 아니라 국제표준화활동이 활발히 이루어지고 있다. 지금까지 표준화활동은 대체로 ITU와 같은 공식적인 국제표준화기구를 통하여 이루어져 왔으나 최근 세계경제의 글로벌화에 따라 기업이 시장경쟁력 향상을 위한 전략적 수단으로서 공식표준보다 사실상표준을 활용하는 경향이 두드러져 표준화활동의 대변혁시대를 맞이하고 있다. 이러한 표준화환경의 변화에 따른 사실상표준의 중요성이 부각되면서 특정기술을 토대로 한 포럼활동이 최근 매우 활발히 이루어지고 있다. 따라서 본 논문에서는 우선 최근 큰 변혁기를 맞이하고 있는 표준화환경의 변화상을 살펴보고 이에 따른 표준화의 역할변화와 공식표준과 사실상표준의 차이점을 분석해 볼 것이다. 이어 최근 표준화에 중요한 역할을 하는 국제포럼의 주요특성별 분류와 공식표준화기구와 관계, 전반적 활동추세에 대해 분석해 볼 것이다.

The purpose of this study is to find out the structural characteristics of interorganizational networks for women, and to identify the magnitude of efficient structure for network using 30 organizations for women in Buchon. This study attempted to examine the characteristic of interorganizational networks through searching out the central organization and block modeling. The research sample was 30 organizations, and the data analyzed by UCINET V and KP(Krack Plot) 3.1. The results show that public agencies are central organizations of all dimensions(information exchange, client referral, cooperation, resource exchange) and they also play an important part as intermediary of interorganizational network. A prominent characteristics of network is "ggiri-network" that means network between similar agencies. This finding provides important strategy to build and expand the network. Also this finding can be direction of network structure to meet women's needs and empower women.

침입 및 해킹의 사례가 증가함에 따라 네트워크 침입 탐지 및 해킹 대응을 위한 네트워크 보안의 필요성이 증가하고 있으며, 정책 서버를 구축하는 솔루션이 등장하고 있다. 일반적인 정책 정보 모델은 IETF의 정책 프레임워크 워킹 그룹과 DMTF의 CIM 활동을 통해 활발히 표준화가 되고 있다. 이러한 표준들은 그 동안 QoS를 위해 대부분 사용되었으나 우리는 이러한 표준을 네트워크 보안 정책 시스템에 맞게 확장하여 네트워크 보안 정책 정보 모델을 구축한다. 본 논문은 패킷 헤더 필드들을 변수화하고 네트워크 보안 정책 정보 모델에서 침입 탐지 및 해킹 대응에 대한 정책을 모델링하는 방법을 제시한다.
