In Korea, starting with the Government 3.0 Policy, the utilization of public data as an important driving force to promote economic growth has been highlighted as a major issue. However Korea is currently only able to open and provide accumulated data stored in the public domain. To resolve this issue, we need to not only open and provide public information, but also to create new information by linking the data and developing related services. Thus, this study analyzes the linkability of public information and provides lists of the linkable public data. In order to do this, we first have performed preconditioning processes on the accessibility and workability of the data. Next, we have deduced the major keywords in public data through analyzing the morphemes, and then the core keywords (Top 10) and their linkable keyword lists through an analysis of social networks. Based on the outcome of this study, a subsequent study will deduce new information by linking the public data and creating various services and information contents. Furthermore, not only conceptual but also practical linking measures need to be created, and a related law must be prepared.

This study aimed to present that the understanding of the relational structure among stakeholders of a national park with the usage of 'social network analysis' can help more effectively to diagnose conflicts among stakeholders and to resolve them, Conducting a telephone-interview survey with 12 stakeholders of the Taean-Haean National Park, Republic of Korea, this study examined their perception of conflicts related to the park, and compared their social networks when their conflicts emerged with their networks when the conflicts did not appear. When the conflicts appeared, the more respondents tried to seek other information sources apart from the Korea National Park Service (KNPS) and the fewer interactions among the stakeholders occurred than when the conflicts were not present. Based on the findings, it was suggested that KNPS need not to directly distribute information to the stakeholders, and to create the third party to generate more interaction and cooperative relationship among the stakeholders, Thus, it can be said that the employment of social network analysis is worth being employed in the study of conflict management in national parks.

This study presents an empirical analysis of job search behaviors by using the 3rd Korean Labor and Income Panel Study (KLIPS) data. The first finding of the study is that specific job search methods, respectively categorized as the indirect and the formal pattern, show the contrasting consequences of causality, as given job searchers'personal attributes and other social factors. Secondly, this analysis confirms that job searchers' education level is the most important factor that influences their behavioral patterns in a consistent manner. Moreover, it is evident in this exploratory study that job searchers' social network (particularly whether to have close ties with relatives of high social rank) is a statistically important factor to influence the extent of job search methods in use, while their fathers' education level also significantly affects the choice of job search patterns.

네트워크로 구성된 시스템은 물질, 에너지, 신호 등의 입력(input)이 주어졌을 때, 경로 추적, 즉 라우팅(routing)을 통해 출력(output)으로 연결되고, 이를 반응함수로 나타낼 수 있다. 같은 입력값이라도 네트워크에 따른 연결 구조와 라우팅 과정에서 소요되는 시간차에 따라 출력값이 달라질 수 있다. 좋은 예로 강우에 따른 유출반응함수를 나타내는 자연 하천망을 들 수 있다. 이론적으로 순간의 입력이 주어졌을 때 (입력의 지속시간이 0), 출력은 순간반응함수로 표현된다. 자연 하천망에 대한 선행연구에서는 강우강도에 따라 순간반응함수가 변화한다는 비선형성이 알려졌다. 하지만, 비선형성을 가져오는 물리적 과정에 대해서는 많은 연구가 필요하다. 이 연구는 격자 형태로 주어진 임의의 네트워크에서 각 격자에 대해 순간반응함수를 구하는 분포형 모형을 제시한다. 입력자료와 라우팅 방법에 따른 연결 구조 및 순간반응함수의 변화를 격자 별로 확인하고, 이를 통해 시스템의 비선형성을 고려할 수 있는지 고찰하였다.

The crisis of western welfare states and the spread of neoliberalism opened up the debate on community question and paid attention to community to cope with diverse social crises. There has been increasing recognition for the need to see World Heritage in terms of place and local community which had formed it rather than an object for conservation separated from the place where it is located. In addition, the conservation and use of cultural heritage can lead to the region's sustainable development and in turn is possible with the region's overall development. However, the Operational Guidelines for the Implementation of the World Heritage Convention does not specify the definition and geographic extent of community. This paper considers place-based communities, Sahachons and religious communities, Sindohoes of seven Buddhist monasteries in preparation for inscription on the UNESCO World Heritage List, and analyzes social networks of these two types of communities to see their consistency with their general characteristics. Social networks analyses indicates that some monasteries show significant differences between Sahachons and Sindohoes, but others do not. This result implies that communities should be seen as processes of constantly reconstituting their features and boundaries under their specific surroundings which are also in constant changes, thus requiring empirical studies.

This study selected 127 powerful Korean film producers, directors, and actors whose stable audience drawing power has been proven over the past seven years from 2013 to 2019, and viewed their network through social network analysis(SNA) to explain their power structure. It also explained the changes compared to the results of previous studies conducted on box office hits from 1998 to 2012. The producers who showed the highest audience drawing power over the past seven years were KANG Hae-jung, JANG Won-seok, LEE Eugene, HAN Jae-duk. BONG Joon-ho, KIM Yong-hwa, and RYOO Seung-wan as directors and SONG Kang-ho, HA Jung-woo, and HWANG Jung-min as actors were confirmed to exhibit the most stable audience drawing power. Meanwhile, the network formed by the 127 leading producers, filmmakers, and actors was analyzed based on closeness/ degree/eigenvector/betwenness centrality, and the result discovered a strong network involving JANG Won-seok, HAN Jae-duk, CHO Jin-woong, Don LEE, and HWANG Jung-min. This study is meaningful in that it included producers, the position which has never been discussed in previous local studies to analyze the network influencing star casting, and selected accurate box office hits by checking whether the concerned films actually reached break-even point rather than simply relying on the number of audiences or total revenue they garnered. Nonetheless, it left a hole to be filled in that it did not include the role of the management companies in the network. Therefore, a relevant follow-up discussion would be needed.

Recently, the number of students who get double majors has tended to increase in many universities. As results, many problems occur because immoderate inflow of double-major students is concentrated in a specific popular department. In this paper, we study the characteristic of inflow and outflow of double majors using social network analysis and decision tree analysis. According to the results, SAT score affected the inflow of double majors the most. Additionally, department category, course evaluation score, employment rate also affected the inflow of double majors in the order named. On the other hand, department category affected the outflow of double majors the most. Additionally, SAT score, employment rate, course evaluation score also affected the outflow of double majors in the order named.

We analyzed the social issue 'image of the elderly' using Big Data and Social Network Analysis. First, we analyzed the words extracted by the text mining technique by inputting the keyword 'elderly'. As a result of analysis, the image of the elderly viewed through media such as cafes, blogs, etc. Representing the trend of the public was using the word 'Senior' the most. The image of the elderly is expressed using the word having the highest frequency in the top 10, "The elderly are 'Senior' people who are respected by society, they are organized to earn money, to earn their qualifications, to health, and to 'Seniors' who desire to work healthy up to 100 years old". The purpose of this study is to differentiate from the existing analysis method by analyzing the macro-level image of the elderly including the social discourse by collecting vast amount of data and analyzing it with the social networking technique. When the image of the elderly that the public perceives is positively expressed as 'Senior', it can be said that the direction of the current elderly policy is evaluated as a desirable direction. On the other hand, it was able to feel the 'desire' of the public who wanted to be evaluated. Therefore, the policy direction of the elderly to be applied in the future should be the policy that enables the elderly to be perceived as 'Necessary existence' in society by taking on social roles. In addition, we proposed to implement the policy of the elderly that reflects priorities such as job creation, welfare, and alienation that can activity and maintain health.
