본 연구에서는 오픈소스 소셜네트워크 소프트웨어인 Humhub를 사용하여 온라인 학습 커뮤니티 사이트를 구축하고, 온라인 사이트에서 그룹을 만들어 그룹내에서 질의 응답을 통한 지식의 사회적 구성이 가능하도록 하였다. 학습 커뮤니티 사이트에 질의 응답에 대한 학습 자료들이 축적되게 함으로써 학습자들이 언제든지 찾아서 학습할 수 있고, 자기 주도적인 학습 공동체를 만들어 지식을 소비하는 것 뿐만 아니라 지식을 재구성 할 수 있는 기회를 제공하였다. 또한 수식 입력이 가능하도록 수식 입력 기능을 개발하여 학습자들이 온라인으로 수식을 사용할 수 있도록 하였다. 온라인 학습 커뮤니티 사이트는 탐구 기반 정보 교육에 활용될 수 있다.

This study would understand the overall perception of our society about public libraries, analyzing the texts related to public libraries, utilizing the semantic connection network & sentiment analysis. For this purpose, this study collected data from the last five years with keywords, 'Library' and 'Lifelong Learning Center' from January 1, 2016 through November 30, 2020 through the blogs and cafés of major domestic portal sites. With the collected data, text mining, centrality of keywords, network structure, structural equipotentiality, and sensitivity analyses were conducted. As a result of the analysis, First, 'reading' and 'book' were identified as representative keywords that form the social perception of public libraries. Second, it turned out that there were keywords related to the use of the library and the untact service due to the recent spread of COVID-19. Third, in seeking a plan for the development of public libraries through the keywords drawn to have positive meanings, it is necessary to create continuous services that can form a new image of the library, breaking away from the existing fixed role and image of the library and increase the convenience of use. Fourth, facilities and facilities for library services were recognized from a neutral point of view. Fifth, the spread of infectious diseases, social distancing, and temporary closure and closure of libraries are negatively related to public libraries, and awareness of librarians has been identified as negative keywords.

Based on the Construal Level Theory, we aim to study a most favorable fit among the advertising model, media type, and message construals, which are important factors in an advertisement. A two (social distance of the ad model in an ad: distal (low similarity) vs proximal (high similarity) by two (social distance of a media type: distal (portal) vs. proximal (SNS)) by two (message construal: abstract vs concrete) laboratory experiment was conducted to examine attitude changes on ad messages. The results show that abstract messages were more effective in attitude toward advertisement and purchase intention under the distal social distance (i.e. advertising model in low-similarity and portal media type) while concrete messages were so under the proximal social distance and SNS media type.

The popularity of Social Network Service (SNS) providing web sites has increased continuously by using a variety of mobile devices. The study results show that security of SNS, efficiency of SNS, safety, empathy of SNS quality, easy of use of SNS, assurance of SNS, service variety of SNS are having positive impact to some degree on the user satisfaction. Further, the user satisfaction of SNS users have a positive impact on the continuance usage intention of SNS users. This results show that various SNS qualities are necessary to actively explore and obtain further information that users intend to find, while they are insufficient in function to provide the information other users require or exchange information with other users through the SNS.

This paper examines a highly used social networking site (SNS) by studying the behavior of more than 11 million members over a 20 month period. The importance of the most highly active members to the overall network is demonstrated by the significant fraction of total visits by extremely active members in a given period but such members have surprisingly short lifespans (an average of only 2.5 months) as social hubs. We form and test a number of hypotheses concerning these social hubs and the determinants of their lifespan. We find that the speed of achieving social hub status increases the lifespan of a social hub. The norm of reciprocity is strongly confirmed to be present in the social hub population as visits are reciprocated. We also find that increasing local dominance in terms of activities over neighboring agents leads to a longer lifespan of a social hub. Contrary to expectations, local clustering in the vicinity of social hubs is smaller (rather than larger) than overall clustering. We discuss managerial implications in the paper.

온라인 소셜 네트워크 서비스(online social network service)를 사용하는 사용자의 증가와 더불어 Twitter, LinkedIn, Tumblr 등 다양한 주제의 SNS들이 등장하고 있다. 사용자들은 SNS에 자신의 정보를 자발적으로 제공하고 서비스를 사용하나, 대용량 데이터 처리 기술의 발전과 프라이버시에 대한 인식이 고취됨에 따라 SNS 이용에 따른 프라이버시 침해가 문제점으로 부각되고 있다. 이를 해결하기 위해 기계 학습에 기반을 둔 SNS 상의 프라이버시 보호 기법들이 연구되어왔으며, 지금도 활발히 연구가 진행중이나 새로운 SNS의 등장에 따른 프라이버시 침해 사례들이 지속적으로 제기되고 있다. 본 논문은 SNS에서 써드 파티 애플리케이션 개발자, 혹은 서비스 제공자가 악의를 가지고 SNS 사용자의 프라이버시를 침해하는 상황에서 사용자가 프라이버시 유출을 사전 탐지하는 기법을 제안한다.

Due to the implementation of COVID-19 distancing, interest and users in 'home training' are rapidly increasing. Therefore, the purpose of this study is to identify the perception of 'home training' through big data analysis on social media channels and provide basic data to related business sector. Social media channels collected big data from various news and social content provided on Naver and Google sites. Data for three years from March 22, 2020 were collected based on the time when COVID-19 distancing was implemented in Korea. The collected data included 4,000 Naver blogs, 2,673 news, 4,000 cafes, 3,989 knowledge IN, and 953 Google channel news. These data analyzed TF and TF-IDF through text mining, and through this, semantic network analysis was conducted on 70 keywords, big data analysis programs such as Textom and Ucinet were used for social big data analysis, and NetDraw was used for visualization. As a result of text mining analysis, 'home training' was found the most frequently in relation to TF with 4,045 times. The next order is 'exercise', 'Homt', 'house', 'apparatus', 'recommendation', and 'diet'. Regarding TF-IDF, the main keywords are 'exercise', 'apparatus', 'home', 'house', 'diet', 'recommendation', and 'mat'. Based on these results, 70 keywords with high frequency were extracted, and then semantic indicators and centrality analysis were conducted. Finally, through CONCOR analysis, it was clustered into 'purchase cluster', 'equipment cluster', 'diet cluster', and 'execute method cluster'. For the results of these four clusters, basic data on the 'home training' business sector were presented based on consumers' main perception of 'home training' and analysis of the meaning network.

SNS is perceived as an effective tool for sharing news and enabling news content to reach many more users than before. And some users think that SNS is an important source to get news. This study's purpose is to understand the key factors contributing to behavior of news consumption on social network sites in Cambodia and its influence. We identified three key factors including convenience, recency, and variety; however, recency showed less significant effect on news consumption on SNS. Besides the key factors, it also seeks to understand the impact of news consumption on social engagement and government's transparency in Cambodia. The analytical results achieved through the Partial Least Squares (PLS) approach.

최근 들어, 소셜 네트워크 서비스(Social Network Service)의 도입과 함께 이를 다양한 목적으로 활용하고자 하는 연구가 활발하게 진행되고 있다. 소셜 네트워크 서비스 활용을 위한 연구를 진행하기 위해서는 우선 관련 문헌을 검토하고 연구 경향을 파악하는 것이 필요하다. 하지만, 소셜 네트워크 서비스가 보편화된 2007년 이후부터 진행된 관련 연구는 그 양이 방대하여 많은 양의 관련 연구 문헌을 조사하는 것은 상당히 어려운 작업이다. 따라서 본 연구에서는 소셜 네트워크 서비스 중 트위터를 중심으로 관련 연구들을 체계적으로 분석하여 연구의 경향성을 밝힌다. 특히 체계적인 문헌 조사와 분석을 위해 SLR(Systematic Literature Review) 기법을 이용한다. 문헌 조사를 위해 5개의 잘 알려진 문헌 제공처를 선정하고, 128개의 문헌 조사 대상 연구를 선정하였다. 다양한 경향성을 파악하기 위하여 2007년 이후 연구들의 그룹과 2011년 이후 연구들의 그룹으로 나누어 조사를 실시하였다. 조사 결과 2007년 이후 트위터 관련 연구는 "Application", "User Content Analysis" 및 "User Activity" 주요 연구주제와 관련한 연구가 가장 많이 이루어지고 있었다. 이외에도 주요 연구주제별 세부 연구주제의 경향, 피인용수에 따른 연구 경향, 실험자료의 규모에 따른 연구경향 및 저자의 특성 등 다양한 관점에서 결과를 분석한다.
