This study tried to identify factors affecting online activity before and after the COVID-19 pandemic. To this end, the effects of consumer innovativeness, self-esteem, and need for cognition on the activity of online media such as Internet and social media were investigated, and whether privacy concerns had a moderating effect. For this study, survey data from 2019(before the outbreak of COVID-19) to 2021(after the outbreak of COVID-19) of the 'Korea Media Panel Survey' surveyed by the Korea Information Society Development Institute was used for analysis. The research results that affect Internet activity are as follows. Before the outback of COVID-19, it was found that hedonic innovativeness and social innovativeness had a positive effect and cognitive innovativeness had a negative effect on increasing Internet activity. There was no moderating effect on privacy concerns. The period after the outbreak of COVID-19, need for cognition was found to have a positive effect on increasing social media activity. In addition, the moderating effect of privacy concerns was found in the relationship between need for cognition and Internet activity. There was no privacy concern effect before the outbreak of COVID-19, and the privacy concern effect appeared on functional innovation and need for cognition after the outbreak of COVID-19. This study aims to present various implications for companies to understand the characteristics of online consumers using the Internet and social media after the pandemic.

본 연구는 청소년들의 온라인 사회적 활동에 있어 이들이 오프라인에서 형성하고 있는 사회적 네트워크에서의 지위가 어떤 특성을 나타내는지를 살펴보고 이러한 사회적 지위가 온라인에서의 사회적 활동에 미치는 영향을 파악하고자 하는 것이다. 이를 위해 먼저 청소년들이 오프라인에서 형성하고 있는 사회적 네트워크에서의 지위를 개인 네트워크와 학교 네트워크로 나누어 살펴보았다. 그 결과, 개인 네트워크에서는 사회적 지위를 나타내는 사회적 유대와 사교성이 활동성과 유의미한 상관관계가 있는 것으로 나타났으며, 학교 네트워크의 사회적 지위를 나타내는 중앙성 지표인 인접중앙성과 매개중앙성은 활동성과 상관관계가 존재하지 않는 것으로 나타났다. 또한 청소년의 개인 네트워크에서는 사회적 유대가 클수록, 사교성이 클수록 온라인의 활동 깊이가 높고 온라인의 활동 넓이도 높은 것으로 나타났다.

Social network games (SNGs), a rapidly growing online game genre, are built and played on social network sites. SNGs provide an online world for enjoying leisure time and interpersonal communication, and an increasing numbers of college students are involved in such game-playing as a leisure time activity. Despite the popularity, relatively few studies have been conducted to investigate the nature of game players, especially the meaning of such leisure time behavior by college students. This paper's aim was to explore a subjective meaning structure of online social network game play. The means-end chain model was used to link attributes of SNGs to the underlying values of game playing as a leisure activity. The results revealed two emerging end-values: the need for bridging and a sense of belonging. This study sheds light on the meaning of college students' leisure activities when playing social network games.

본 논문은 온라인 커뮤니티 활동이 오프라인의 사회적 자본에 미치는 영향에 대해 살펴보고, 개인적 특성에 따라 효과가 어떻게 다를 수 있는지를 이론적 실증적으로 분석한 연구이다. 9479개 대량의 연구 샘플을 바탕으로 위계적 회귀분석과 이원 공분산 분석을 수행하였다. 연구 결과에 따르면 온라인 커뮤니티 활동과 오프라인 사회적 자본 간에 정의 관계가 성립함을 확인하였고, 나이가 많은 사람들에게서 더욱 강한 효과가 있다는 것을 확인하였다. 본 연구에서는 인터넷 커뮤니티 활동이 사회적 자본을 강화한다는 기존 연구의 주장을 실증적으로 검증하면서, 온라인의 사회적 자본을 중심으로 논의되고 있는 최근의 연구들을 확장시켜 오프라인의 사회적 자본 형성에도 긍정적인 영향을 미친다는 결론을 도출하였다. 또한 중 장 노년층의 사회적 자본 형성에서 온라인 활동이 중요한 역할을 할 수 있다는 시사점을 제공한다. 장기적인 관점에서 사회적 자본의 양적 질적 개선을 위해 온라인 커뮤니티 활성화가 필요하며, 이러한 공동의 공간이 많은 사람들에게 공유되고 활용될 수 있도록 하는 노력이 지속적으로 필요할 것이다.

스마트폰의 보급과 온라인 소셜 네트워크 서비스의 발전으로 사용자들은 많은 콘텐츠를 생산하거나 서로 공유한다. 이로 인해 사용자는 자신이 원하지 않는 콘텐츠를 받아보거나 소비함으로써 많은 시간을 소요하게 된다. 이와 같은 문제를 해결하기 위해 소셜 네트워크 사용자에게 적합한 콘텐츠를 추천하기 위한 기법들이 활발하게 연구되고 있다. 본 논문에서는 온라인 소셜 네트워크 사용자에게 협업 필터링을 이용하여 적합한 콘텐츠를 추천하는 기법을 제안한다. 제안하는 기법은 추천의 정확성을 낮추는 사용자의 데이터를 제거하기 위해서 사용자 신뢰도를 고려한다. 사용자의 신뢰도는 온라인 소셜 네트워크의 사용자 행위를 분석해서 도출한다. 사용자의 신뢰도를 다양한 관점에서 평가하기 위해서 기존기법에서 사용하지 않았던 사용자 행위들을 수집해서 사용한다. 다양한 성능평가를 통해 제안하는 기법이 기존 기법보다 우수함을 보인다.

Purpose This study collects data of the recently activated online black market and analyzes it to present a specific method for preparing for a hacking attack. This study aims to make safe from the cyber attacks, including hacking, from the perspective of individuals and businesses by closely analyzing hacking methods and tools in a situation where they are easily shared. Design/methodology/approach To prepare for the hacking attack through the online black market, this study uses the routine activity theory to identify the opportunity factors of the hacking attack. Based on this, text mining and social network techniques are applied to reveal the most dangerous areas of security. It finds out suitable targets in routine activity theory through text mining techniques and motivated offenders through social network analysis. Lastly, the absence of guardians and the parts required by guardians are extracted using both analysis techniques simultaneously. Findings As a result of text mining, there was a large supply of hacking gift cards, and the demand to attack sites such as Amazon and Netflix was very high. In addition, interest in accounts and combos was in high demand and supply. As a result of social network analysis, users who actively share hacking information and tools can be identified. When these two analyzes were synthesized, it was found that specialized managers are required in the areas of proxy, maker and many managers are required for the buyer network, and skilled managers are required for the seller network.
