본 연구는 새로운 '혼밥'문화에 대한 중립적인 관점의 이해가 필요하여 직장인들의 '혼밥' 경험과 '혼밥' 유지 과정을 설명하는 실체이론을 개발하고자 하였다. 이를 위해서 서울과 경기지역의 직장에 다니는 직장인이면서 일주일에 전체 식사의 70% 이상 '혼밥'을 하고 5년 이상 '혼밥'을 유지하고 있으며 자발적인 선택으로 '혼밥'을 하고 있는 남녀 10명을 대상으로 심층면접을 실시하였고 수집된 자료는 질적연구 방법 중의 하나인 근거이론방법을 적용하여 자료를 분석하였다. 연구결과, '혼밥'을 유지하는 과정에 대한 패러다임 모형이 도출되었다. '혼밥' 유지 과정에서 인과적 조건은 '조율을 시도하지 않음'으로, 중심현상은 '효율 우선의 욕구를 좇음'으로 드러났다. 맥락적 조건은 '치열한 경쟁 분위기', '조직문화의 약화', '개인주의 문화의 확산'으로, 중재적 조건은 '개인의 성격적 특성과 정서경험', '조직문화 없는 직무특성'으로 나타났다. 중심현상에 대한 참여자의 작용/상호작용 전략은 '내적갈등을 수용하기', '자율적으로 행동하기', '매체를 통해 관계 찾기', '피상적 관계 거리두기'로 나타났다. 결과는 '탐색의 시간을 향유함', '자기돌봄에 충실함', '고독한 편리주의자가 됨', '균형의 필요를 알아차림'으로 드러났다. 핵심범주는 '효율 우선을 따라 자신에게 충실하며 함께함의 중요성을 알아감'으로 밝혀졌다. '혼밥'을 시작하면서 시간효율을 저울질하는 단계, 외부시선에서 자유롭지 못하여 불안한 갈등단계, 자신이 선택한 '혼밥' 행위를 계획하고 합리화하는 조정단계, '혼밥'을 하면서도 '함께함'의 중요성을 알아가는 균형단계를 거치면서 혼밥을 유지하고 있는 것으로 나타났다. 본 연구는 직장인의 '혼밥'경험과 '혼밥' 유지 과정에 대한 통합적 탐색을 토대로 새로운 '혼밥'문화에 대한 이해를 도모하였고 우리 사회가 새로운 '혼밥'문화를 수용하고 다양한 문화의 공존을 인정할 수 있도록 돕고자 하였다.

소셜 네트워크는 사용자들의 공통된 관심사, 경험, 그리고 일상 생활들을 함께 공유하기 위해 소셜 네트워크 상 사람들을 서로 연결시켜주는 거대한 커뮤니케이션 플랫폼이다. 소셜 네트워크상의 사용자들은 포스팅, 댓글, 인스턴스 메시지, 게임, 소셜 이벤트 외에도 다양한 애플리케이션을 통해 다른 사용자들과 소통하고 개인 정보 관리하는데 많은 시간을 소비한다. 소셜 네트워크 상의 풍부한 사용자 정보는 추천시스템이 추천 성능을 향상시키기 위해 필요한 큰 잠재력이 되었다. 대부분의 사용자들은 어떤 상품을 구매하기 전 가까운 관계이거나 같은 성향을 가진 사람들의 의견을 반영하여 의사 결정을 하게 된다. 그러므로 소셜 네트워크에서의 사용자 관계는 추천시스템을 위한 사용자 선호도 예측을 효율적으로 높이는데 중요한 요소라 할 수 있다. 일부 연구자들은 소셜 네트워크에서의 사용자와 다른 사용자들 사이의 상호작용 즉, 소셜 관계(social relationship)와 같은 소셜 데이터가 추천시스템에서 추천의 질에 어떠한 영향을 미치는가를 연구하고 있다. 추천시스템은 아마존, 이베이, Last.fm과 같은 큰 규모의 전자상거래 사이트 또한 채택하여 사용되는 시스템으로, 추천시스템을 위한 방법으로는 협업적 여과 방법과 내용 기반 여과 방법이 있다. 협업적 여과 방법은 사용자들의 선호도 학습에 의해 사용자가 아직 평가하지 않은 아이템 중 선호할 수 있는 아이템을 정확하게 제안하기 위한 추천시스템 방법 중 하나이다. 협업적 여과는 사용자들의 데이터에 초점을 맞춘 방법으로 유사한 배경과 선호도를 가지는 사용자들로부터 정보를 수집하여 사용자들의 선호도 예측을 자동으로 발생시킨다. 특히 협업적 여과는 근접한 이웃 사용자들에 의해서 목적 사용자가 선호할 수 있는 아이템을 제시하는 것으로 유사한 이웃 사용자를 찾는 것이 중요하다. 좋은 이웃 사용자 발견은 사용자와 아이템을 고려하는 방법이 일반적이다. 각 사용자는 아이템 즉, 영화, 상품, 책 등에 자신의 선호도를 나타내기 위하여 평가 값을 입력하고, 시스템은 이를 바탕으로 사용자-평가 행렬을 구축한다. 이 사용자-평가 행렬은 목적 사용자와 유사하게 아이템을 평가한 사용자 그룹을 찾기 위한 것으로, 목적 사용자가 아직 평가하지 않은 아이템에 대하여 사용자-평가 매트릭스를 통해 그 평가 값을 예측한다. 현재 이 협업적 여과 방법은 전자상거래와 정보 검색에서 적용되어 개인화 시스템에 효율적으로 사용되고 있다. 하지만 초기 사용자 문제, 데이터 희박성 문제와 확장성 그리고 예측 정확도 향상 등 해결해야 할 과제가 여전히 남아 있다. 이러한 문제들을 해소하기 위해 많은 연구자들은 하이브리드, 신뢰기반, 소셜 네트워크 기반 협업적 여과와 같은 다양한 방법을 제안하였다. 본 논문에서는 전통적인 협업적 여과 방식의 예측 정확도와 추천 성능을 향상시키기 위해 소셜 네트워크에 존재하는 소셜 관계를 이용한 협업적 여과 시스템을 제안한다. 소셜 관계는 소셜 네트워크 서비스 중 하나인 페이스북 사용자들이 남긴 포스팅과 사용자의 소셜 네트워크 친구와 의견 교류 중 남긴 코멘트와 같은 사용자 행동을 기반으로 정의된다. 소셜 관계를 구축하기 위해 소셜 네트워크 사용자의 포스팅과 댓글을 추출하고, 추출된 텍스트에 불용어 및 특수 기호 제거와 스테밍 등 전처리를 수행하였다. 특징 벡터는 TF-IDF를 이용하여 전처리된 텍스트에 나타난 각 단어에 대한 특징 점수를 계산함으로써 구축된다. 본 논문에서 이웃 사용자를 결정하기 위해 사용되는 사용자 간 유사도는 특징 벡터를 이용한 사용자 행동 유사도와 사용자의 영화 평가를 기반으로 한 전통적 방법의 유사도를 결합하여 계산된다. 제안하는 시스템은 목표 사용자와 제안한 방법을 통해 결정된 이웃 사용자 집단을 기반으로 목표 사용자가 평가하지 않은 아이템에 대한 선호도를 예측하고 Top-N 아이템을 선별하여 사용자에게 아이템을 추천하게 된다. 본 논문에서 제안하는 방법을 확인하고 평가하기 위하여 IMDB에서 제공하는 영화 정보 기반으로 영화 평가 시스템을 구축하였다. 예측 정확도를 평가하기 위해 MAE 값을 이용하여 제안하는 알고리즘이 얼마나 정확한 추천을 수행하는지에 대한 예측 정확도를 측정하였다. 그리고 정확도, 재현율 및 F1값 등을 활용하여 시스템의 성능을 평가하였으며, 시스템의 추천 품질은 커버리지를 이용하여 평가되었다. 실험 결과로부터 본 논문에서 제안한 시스템이 보다 더 정확하고 좋은 성능으로 사용자에게 아이템을 추천하는 것을 볼 수 있었다. 특히 소셜 네트워크에서 사용자 행동을 기반으로 한 소셜 관계를 이용함으로써 추천 정확도를 6% 향상시킴을 보였다. 또한 벤치마크 알고리즘과의 성능비교 실험을 통해 7% 향상된 추천 성능의 결과를 보여준다. 그러므로 사용자의 행동으로부터 관찰된 소셜 관계를 CF방법과 결합한 제안한 방법이 정확한 추천시스템을 위해 유용하며, 추천시스템의 성능과 품질을 향상시킬 수 있음을 알 수 있다.

Currently, Social Media, it has widely a renown keyword and its related social trends and businesses have been fastly applied into various contexts. Social media has become an important research area for scholars interested in online technologies and cyber space and their social impacts. Social media is not only including web-based services but also mobile-based application services that allow people to share various style information and knowledge through online connection. Social media users have tendency to common identity- and bond-attachment through interactions such as 'thumbs up', 'reply note', 'forwarding', which may have driven from various factors and may result in delivering information, sharing knowledge, and specific experiences et al. Even further, almost of all social media sites provide and connect unknown strangers depending on shared interests, political views, or enjoyable activities, and other stuffs incorporating the creation of contents, which provides benefits to users. As fast developing digital devices including smartphone, tablet PC, internet based blogging, and photo and video clips, scholars desperately have began to study regarding diverse issues connecting human beings' motivations and the behavioral results which may be articulated by the format of antecedents as well as consequences related to contents that people create via social media. Social media such as Facebook, Twitter, or Cyworld users are more and more getting close each other and build up their relationships by a different style. In this sense, people use social media as tools for maintain pre-existing network, creating new people socially, and at the same time, explicitly find some business opportunities using personal and unlimited public networks. In terms of theory in explaining this phenomenon, social capital is a concept that describes the benefits one receives from one's relationship with others. Thereby, social media use is closely related to the form and connected of people, which is a bridge that can be able to achieve informational benefits of a heterogeneous network of people and common identity- and bonding-attachment which emphasizes emotional benefits from community members or friend group. Social capital would be resources accumulated through the relationships among people, which can be considered as an investment in social relations with expected returns and may achieve benefits from the greater access to and use of resources embedded in social networks. Social media using for their social capital has vastly been adopted in a cyber world, however, there has been little explaining the phenomenon theoretically how people may take advantages or opportunities through interaction among people, why people may interactively give willingness to help or their answers. The individual consciously express themselves in an online space, so called, common identity- or bonding-attachments. Common-identity attachment is the focus of the weak ties, which are loose connections between individuals who may provide useful information or new perspectives for one another but typically not emotional support, whereas common-bonding attachment is explained that between individuals in tightly-knit, emotionally close relationship such as family and close friends. The common identify- and bonding-attachment are mainly studying on-offline setting, which individual convey an impression to others that are expressed to own interest to others. Thus, individuals expect to meet other people and are trying to behave self-presentation engaging in opposite partners accordingly. As developing social media, individuals are motivated to disclose self-disclosures of open and honest using diverse cues such as verbal and nonverbal and pictorial and video files to their friends as well as passing strangers. Social media context, common identity- and bond-attachment for self-presentation seems different compared with face-to-face context. In the realm of social media, social users look for self-impression by posting text messages, pictures, video files. Under the digital environments, people interact to work, shop, learn, entertain, and be played. Social media provides increasingly the kinds of intention and behavior in online. Typically, identity and bond social capital through self-presentation is the intentional and tangible component of identity. At social media, people try to engage in others via a desired impression, which can maintain through performing coherent and complementary communications including displaying signs, symbols, brands made of digital stuffs(information, interest, pictures, etc,). In marketing area, consumers traditionally show common-identity as they select clothes, hairstyles, automobiles, logos, and so on, to impress others in any given context in a shopping mall or opera. To examine these social capital and attachment, we combined a social capital theory with an attachment theory into our research model. Our research model focuses on the common identity- and bond-attachment how they are formulated through social capitals: cognitive capital, structural capital, relational capital, and individual characteristics. Thus, we examined that individual online kindness, self-rated expertise, and social relation influence to build common identity- and bond-attachment, and the attachment effects make an impact on both the willingness to help, however, common bond seems not to show directly impact on information sharing. As a result, we discover that the social capital and attachment theories are mainly applicable to the context of social media and usage in the individual networks. We collected sample data of 256 who are using social media such as Facebook, Twitter, and Cyworld and analyzed the suggested hypotheses through the Structural Equation Model by AMOS. This study analyzes the direct and indirect relationship between the social network service usage and outcomes. Antecedents of kindness, confidence of knowledge, social relations are significantly affected to the mediators common identity-and bond attachments, however, interestingly, network externality does not impact, which we assumed that a size of network was a negative because group members would not significantly contribute if the members do not intend to actively interact with each other. The mediating variables had a positive effect on toward willingness to help. Further, common identity attachment has stronger significant on shared information.

정보기술의 비약적 발전에 힘입어, 오늘날 기업들은 지금까지 축적한 고객 데이터를 기반으로 맞춤형 서비스를 제공하는 것에 많은 관심을 가지고 있다. 고객에게 소구하는 맞춤형 서비스를 효과적으로 제공하기 위해서는 우선 그 고객이 처한 상태나 상황을 정확하게 인지하는 것이 중요하다. 특히, 고객에게 서비스가 전달되는 이른바 진실의 순간에 해당 고객의 감정 상태를 정확히 인지할 수 있다면, 기업은 더 양질의 맞춤형 서비스를 제공할 수 있을 것이다. 이와 관련하여 사람의 얼굴과 행동을 이용하여 사람의 감정을 판단하고 개인화 서비스를 제공하기 위한 연구가 활발하게 이루어지고 있다. 얼굴 표정을 통해 사람의 감정을 판단하는 연구는 좀 더 미세하고 확실한 변화를 통해 정확하게 감정을 판단할 수 있지만, 장비와 환경의 제약으로 실제 환경에서 다수의 관객을 대상으로 사용하기에는 다소 어려움이 있다. 이에 본 연구에서는 Plutchik의 감정 분류 체계를 기반으로 사람들의 행동을 통해 감정을 추론해내는 모형을 개발하는 것을 목표로 한다. 본 연구는 콘텐츠에 의해 유발된 사람들의 감정적인 변화를 사람들의 행동 변화를 통해 판단하고 예측하는 모형을 개발하고, 4가지 감정 별 행동 특징을 추출하여 각 감정에 따라 최적화된 예측 모형을 구축하는 것을 목표로 한다. 모형 구축을 위해 사람들에게 적절한 감정 자극영상을 제공하고 그 신체 반응을 수집하였으며, 사람들의 신체 영역을 나누었다. 특히, 모션캡쳐 분야에서 널리 쓰이는 차영상 기법을 적용하여 사람들의 제스쳐를 추출 및 보정하였다. 이후 전처리 과정을 통해 데이터의 타임프레임 셋을 20, 30, 40 프레임의 3가지로 설정하고, 데이터를 학습용, 테스트용, 검증용으로 구분하여 인공신경망 모형을 통해 학습시키고 성과를 평가하였다. 다수의 일반인들을 대상으로 수집된 데이터를 이용하여 제안 모형을 구축하고 평가한 결과, 프레임셋에 따라 예측 성과가 변화함을 알 수 있었다. 감정 별 최적 예측 성과를 보이는 프레임을 확인할 수 있었는데, 이는 감정에 따라 감정의 표출 시간이 다르기 때문인 것으로 판단된다. 이는 행동에 기반한 제안된 감정예측모형이 감정에 따라 효과적으로 감정을 예측할 수 있으며, 실제 서비스 환경에서 사용할 수 있는 효과적인 알고리즘이 될 수 있을 것으로 기대할 수 있다.

We investigated what factors motivate gamers to participate in a guild and why they continue to be engaged as members of the guild. We find that, based on the result of focus group interviews with MMORPG gamers, social support and self-esteem factors play important roles. Considering both prior research and the focus group interviews we have conducted, we define social support and character control as independent variables. Character identity, guild identity, and self-esteem are proposed as mediating variables while guild flow and game loyalty as dependent variables. Accordingly, we develop the research model and hypotheses, and verify them empirically. Based on our experiences of playing the WoW game, we proposed a research model and conducted focus-group interviews (FGIs). FGIs involve formulating a hypothesis and then collecting some relevant data. FGIs were conducted face-to-face with students of C University in Korea. We formulated structured interview schedules, and the questions were based on our research variables and personal experiences. The questions for the interviews encompassed the following areas: (a) the demographic characteristics of the focus group; (b) the number of years for which respondents had played online games; (c) the motive for starting a game; (d) the number of game-characters assumed by each gamer; (e) the type of game played; and (f) other issues such as the reasons for involvement in the play, the willingness to reuse the game in case new versions were released, etc. On average, it took two hours to interview each of three groups. A primary set of FGIs was conducted with three groups on the premise that there would be some differences caused by character race (Horde vs. Alliance) or by playable server (Normal vs. Combat). With respect to the manner of playing, we found that guild members shared information, felt a sense of belonging, and played computer games for quite a long time through the guild; however, they did not undergo these experiences when playing alone. Gamers who belonged to a specific guild helped other players without expecting compensation for that, freely shared information about the game, gave away items for free, and more generous with other members who made mistakes. The guild members were aware of the existence other members and experienced a sense of belonging through interactions with, and evaluations from, other players. It was clear that social support was shown within the guild and that it played an important role as a major research variable. Based on the results of the first FGIs, a second set of in-depth FGIs was carried out with a focus on the psychology of the individual within the guild and the social community of the guild. The second set of FGIs also focused on the guild's offline meetings. Gamers, over all, recognize the necessity of joining a community, not only off-line but also online world of the guild. They admit that the guild is important for them to easily and conveniently enjoy playing online computer games. The active behavior and positive attitudes of existing guild members can motivate new members of the guild to adapt themselves to the guild environment. They then adopt the same behaviors and attitudes of established guild members. In this manner, the new members of the guild strengthen the bonds with other gamers while feeling a sense of belonging, and developing social identity, thereby. It was discovered that the interaction among guild members and the social support encouraged new gamers to quickly develop a sense of social identity and increase their self-esteem. The guild seemed to play the role of socializing gamers. Sometimes, even in the real world, the guild members helped one another; therefore, the features of the guild also spilled over to the offline environment. We intend to use self-esteem, which was found through the second set of FGIs, as an important research variable. To collect data, an online survey was designed with a questionnaire to be completed by WoW gamers, who belong to a guild. The survey was registered on the best three domestic game-sites: 'WoW playforum,' 'WoW gamemeca,' and 'Wow invent.' The selected items to be measured in the questionnaire were decided based on prior research and data from FGIs. To verify the content of the questionnaire, we carried out a pilot test with the same participants to point out ambiguous questions as a way to ensure maximum accuracy of the survey result. A total of 244 responses were analyzed from the 250 completed questionnaires. The SEM analysis was used to test goodness-of-fit of the model. As a result, we found important results as follows: First, according to the statistics, social support had statistically significant impacts on character control, character identity, guild identity and self-esteem. Second, character control had significant effects on character identity, guild identity and self-esteem. Third, character identity shows its clear impact on self-esteem and game loyalty. Fourth, guild identity affected self-esteem, guild flow and game loyalty. Fifth, self-esteem had a positive influence on the guild flow. These days, the number of virtual community is rising along with its significance largely because of the nature of the online games. Accordingly, this study is designed to clarify the psychological relationship between gamers within the guild that has been generally established by gamers to play online games together. This study focuses on the relationships in which social support influences guild flow or game loyalty through character control, character identity, guild identity, and self-esteem, which are present within a guild in the MMORPG game environment. The study results are as follows. First, the effects of social support on character control, character identity, guild identity and self-esteem are proven to be statistically significant. It was found that character control improves character identity, guild identity and self-esteem. Among the seven variables, social support, which is derived from FGIs, plays an important role in this study. With the active support of other guild members, gamers can improve their ability to develop good characters and to control them. Second, character identity has a positive effect on self-esteem and game loyalty, while guild identity has a significant effect on self-esteem, guild flow and game loyalty. Self-esteem affects guild flow. It was found that the higher the character and guild identities become, the greater the self-esteem is established. Contrary to the findings of prior research, our study results indicate that the relationship between character identity and guild flow is not significant. Rather, it was found that character identity directly affects game players' loyalty. Even though the character identity had no direct effect on increasing guild flow, it has indirectly affected guild flow through self-esteem. The significant relationship between self-esteem and guild flow indicates that gamers achieve flow, i.e., a feeling of pleasure and excitement through social support. Several important implications of this study should be noted. First, both qualitative and quantitative methods were used to conduct this study. Through FGIs, it was observed that both social support and self-esteem are important variables. Second, because guilds had been rarely studied, this research is expected to play an important role in the online community. Third, according to the result, six hypotheses (H1, H5, H6, H7, H8, and H11) setup based on FGIs, were statistically significant; thus, we can suggest the corresponding relationships among the variables as a guideline for follow-up research. Our research is significant as it has following implications: first, the social support of the guild members is important when establishing character control, character identity, guildidentity and self-esteem. It is also a major variable that affects guild flow and game loyalty. Second, character control when improved by social support shows notable influence on the development of character identity, guild identity and self-esteem. Third, character identity and guild identity are major factors to help establish gamers' own self-esteem. Fourth, character identity affects guild flow through self-esteem and game loyalty. The gamers usually express themselves through characters; the higher character identity is, the more loyalty a gamer has. Fifth, guild identity, established within the guild, has clear effects on self-esteem, guild flow and game loyalty. Sixth, qualitative and quantitative methods are employed to conduct this study. Based on the results of focus group interviews and SEM analysis, we find that the social support by guild members and psychological factors are significant in strengthening the flow of guild and loyalty to the game. As such, game developers should provide some extra functions for guild community, through which gamers can play online games in collaboration with one another. Also, we suggest that positive self-esteem which is built up through social support can help gamers achieve higher level of flow and satisfaction, which will consequently contribute to minimizing the possibility for the players to develop negative attitude toward the guild they belong to.

The research conducted here focuses on the effect of factors that affect the behavior of UCC (User Created Content) website users, other than user's rational recognition of how useful a UCC website can be. Most discussions in the existing literature on information systems have focused on users' evaluation how a UCC website can help to attain the users' own goals. However, there are other factors and this research pays attention to an individual's 'personality,' which is stable and biological in nature. Specifically, I have noted here that 'extroversion' and 'neuroticism,' the two common personality factors presented in Eysenck's most representative 'EPQ Model' and 'Big Five Model,' are the two personality factors that affect a site's 'usefulness,' by this I mean how useful does the user consider the website and its content. How useful a site is considered by the user is the other factor that has been regarded as the antecedent factor that influences the adoption of information systems in the existing MIS (Management Information System) research. Secondly, as using or creating a UCC website does not guarantee the user's or the creator's extrinsic motivation, unlike when using the information system within an organization, there is a greater likelihood that the increase in user's activities in relation to a UCC website is motivated by emotional factors rather than rational factors. Thus, I have decided to include the relationship between an individual's personality and what they find pleasurable in the research model. Thirdly, when based on the S-O-R Paradigm of Mehrabian and Russell, the two cognitive factors and emotional factors are finally affected by stimulus, and thus these factors ultimately have an effect on an individual's respondent behavior. Therefore, this research has presented an assumption that the recognition of how useful the site and content is and what emotional pleasure it provides will finally affect the behavior of the UCC website users. Finally, the relationship between the recognition of how useful a site is and how pleasurable it is to useand UCC usage may differ depending on certain situational conditions. In other words, the relationship between the three factors may vary according to how much users are involved in the creation of the website content. Creation thus emerges as the keyword of UCC. I analyzed the above relationships through the moderating variable of the user's involvement in the creation of the site. The research result shows the following: When it comes to the relationship between an individual's personality and what they find pleasurable it is extroverted users who have a greater likelihood to feel pleasure when using a UCC website, as was expected in this research. This in turn leads to a more active usage of the UCC web site because a person who is an extrovert likes to spend time on activities with other people, is sensitive to new experiences and stimuli and thus actively responds to these. An extroverted person accepts new UCC activities as part of his/her social life, rather than getting away from this new UCC environment. This is represented by the term 'Foxonomy' where the users meet a variety of users from all over the world and contact new types of content created by these users. However, neuroticism creates the opposite situation to that created by extroversion. The representative symptoms of neuroticism are instability, stress, and tension. These dispositions are more closely related to stress caused by a new environment rather than this creatingcuriosity or pleasure. Thus, neurotic persons have an uneasy feeling and will eventually avoid the situation where their own or others' daily lives are frequently exposed to the open web environment, this eventually makes them have a negative attitude towards the web environment. When it comes to an individual's personality and how useful site is, the two personality factors of extroversion and neuroticism both have a positive relationship with the recognition of how useful the site and its content is. The positive, curious, and social dispositions of extroverted persons tend to make them consider the future usefulness and possibilities of a new type of information system, or website, based on their positive attitude, which has a significant influence on the recognition of how useful these UCC sites are. Neuroticism also favorably affects how useful a UCC website can be through a different mechanism from that of extroversion. As the neurotic persons tend to feel uneasy and have much doubt about a new type of information system, they actively explore its usefulness in order to relieve their uncomfortable feelings. In other words, neurotic persons seek out how useful a site can be in order to secure their own stable feelings. Meanwhile, extroverted persons explore how useful a site can be because of their positive attitude and curiosity. As a lot of MIS research has revealed that the recognition of how useful a site can be and how pleasurable it can be to use have been proven to have a significant effect on UCC activity. However, the relationship between these factors reveals different aspects based on the user's involvement in creation. This factor of creationgauges the interest of users in the creation of UCC contents. Involvement is a variable that shows the level of an individual's mental effort in creating UCC contents. When a user is highly involved in the creation process and makes an enormous effort to create UCC content (classed a part of a high-involvement group), their own pleasure and recognition of how useful the site is have a significantly higher effect on the future usage of the UCC contents, more significantly than the users who sit back and just retrieve the UCC content created by others. The cognitive and emotional response of those in the low-involvement group is unlikely to last long,even if they recognize the contents of a UCC website is pleasurable and useful to them. However, the high-involvement group tends to participate in the creation and the usage of UCC more favorably, connecting the experience with their own goals. In this respect, this research presents an answer to the question; why so many people are participating in the usage of UCC, the representative form of the Web 2.0 that has drastically involved more and more people in the creation of UCC, even if they cannot gain any monetary or social compensation. Neither information system nor a website can succeed unless it secures a certain level of user base. Moreover, it cannot be further developed when the reasons, or problems, for people's participation are not suitably explored, even if it has a certain user base. Thus, what is significant in this research is that it has studied users' respondent behavior based on an individual's innate personality, emotion, and cognitive interaction, unlike the existing research that has focused on 'compensation' to explain users' participation with the UCC website. There are also limitations in this research. Firstly, I divided an individual's personality into extroversion and neuroticism; however, there are many other personal factors such as neuro-psychiatricism, which also needs to be analyzed for its influence on UCC activities. Secondly, as a UCC website comes in many types such as multimedia, Wikis, and podcasting, these types need to be included as a sub-category of the UCC websites and their relationship with personality, emotion, cognition, and behavior also needs to be analyzed.
