인터넷과 스마트폰의 발전과 함께 소셜 미디어 공유 사이트인 유튜브도 크게 성장하여 수많은 동영상을 공유하는 사이트가 됐다. 사용자들이 유튜브를 통해 동영상을 공유하면서 소셜 데이터를 만들어내고, 많은 동영상들 중에서 본인의 관심사가 반영된 동영상 추천을 원하게 된다. 본 논문에서는 유튜브 데이터를 이용하여 사용자의 사회적 관계와 유튜브의 특징이 반영된 소셜 카테고리 분류 목록을 기반으로 사용자의 소셜 카테고리를 추출한다. 우리는 좀 더 정확하고 의미있는 추천을 위해 추출된 사용자 소셜 카테고리를 이용한 유튜브 동영상을 추천하는 알고리즘을 제안하였다. 또한 실험을 통해 그 유효성을 검증하였다.

The main purposes of this study are to appraise the family-centered case-management (FCCM) practices in terms of building the community networking efforts, and to propose the practical improvement suggestions to overcome the barriers in practicing the current Healthy Families Policy, FCCM. The blended methodology was employed by collecting the quantitative and qualitative data sets including an staff's on-line survey, in-depth interviews(site case studies), and FGIs. As results, the authors found, despite the building and maintaining functional community networks was the essential and critical condition for the FCCM policy deliveries, many staffs have faced hardships in FCCM practices such as building a new network or finding an available and apt network within their communities. The lack of previous experiences in case-management exaggerated the functional difficulties thus, the new staffs were more prone than the staffs with 2 or more years experiences to the misunderstanding about the missions and tasks related to FCCM. Authors suggested that various on-the-job-training should be provided to eliminate those obstacles to build and/or maintain the community network for FCCM. Also, it is necessary for the each institution's director or managers to understand the FCCM and its relation to community networking, and to support FCCM staff members.

This paper examines advertising images of fashion brands in vertical social network site (SNS) from the viewpoints of message strategies. Vertical social network sites are types of social curation systems applied to social networking, where information is selected, organized, and maintained. Fashion brands communicate with consumers by presenting images on vertical SNSs, anticipating improvements in brand image, popularity, and loyalty. Those images portray content for particular brands and seasonal concepts, thus creating paths for product sales information. Marketing via SNSs corresponds to relationship marketing, which refers to long-term interrelationship and value augmentation between the company and consumer, and viral advertising, which relies on word of mouth distribution via social network platforms. Taylor's six-segment message strategy wheel, often used for analyzing viral ads, was applied to conduct a content analysis of the images. A total of 2,656 images of fashion brands advertised on Instagram were selected and analyzed. Results indicated that brand values were somewhat related to the number of followers. Follower rankings and comment rankings were also correlated. In general, fashion brands projected sensory messages most often. Acute need and rational messages were less common than other messages. Sports brands and luxury brands presented sensory messages, whereas fast fashion brands projected routine images most often. Fashion brands promoted on vertical SNSs should portray advertising images that combine message strategies

최근 기업들이 빅데이터를 활용하여 효과적인 마케팅 전략을 전개함에 있어서, 고객의 세부정보를 기반으로 하는 개인화된 마케팅 전략을 활용하고 있다. 하지만 프라이버시 및 개인정보 유출위협이 커짐에 따라 소셜 네트워크 사이트(Social Network Site, 이하 SNS)에서 계정의 개인정보 항목을 삭제하거나 정보공개수준을 통제하는 경향이 높아지고 있다. 이로인해 기업의 마케팅 담당자들은 고객의 세부정보를 파악하는 것에 어려움을 겪고 있다. 본 연구에서는 SNS 중에서 가장 많은 회원 수를 보유하고 있는 Facebook에서 제한된 정보를 바탕으로 성별을 예측하는 분석방법론을 도출하고자 하였다. 본 연구에는 측정도구로 Gaussian RBF, nFactors, randomForest, 그리고 5-fold cross-validation 사용하였다. 그 결과, 성별은 75%, 연령대는 97.85%로 '좋아요' 정보만을 가지고 성별과 연령을 예측할 수 있었다. 즉, 사용자들의 어떠한 세부정보 없이, Facebook의 '좋아요'의 정보를 가지고 인구통계학적인 정보를 추론할 수 있었다. 본 연구의 결과를 바탕으로 개인정보 수집에 어려움을 겪고 있는 기업 및 마케팅 담당자들에게 유용한 가이드 라인을 제시 할 수 있을 것으로 기대한다.

Many empirical studies indicate that SNS use has increased substantially over the last few years. People use SNSs for social purposes, mostly related to the maintenance of existing offline contacts. Such usage may have led to compulsive use of SNSs resulting in addictive behavior. This paper aims to explore factors affecting SNS addiction. Specifically, the study examined the role of personality traits in the Facebook usage among college students. Compared to the rest of world, daily log on the site has grown very quickly in South Korea. And college students constitute a vast majority of Facebook users in South Korea. Results from a survey of 235 college students revealed that extraversion and neuroticism positively predicted Facebook usage. Students who were high in extraversion were more likely to update their profiles, share photo and images with others and give feedback on other's posts. Similarly, those who were high in neuroticism were more likely to share photo and images with others and update their profiles. These findings support previous research. Furthermore, in terms of the effect of personality on SNS addiction, this study found that consciousness was negatively associated with Facebook addiction, while extraversion and neuroticism were positively associated with Facebook addiction.

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.

The purpose of this study was to investigate adolescents' individual and microsystem variables including relationships with parents and friends affecting adolescents' experiences of mobile social networking site (SNS) cyberbullying based on the human ecological perspective. Data came from 344 middle school students who lived with both their parents in the Seoul and Gyunggi areas. A multiple regression analysis showed that adolescents' characteristics, relationships with parents, and friends were associated with their experiences of mobile SNS cyberbullying. These findings suggest that good relationships with parents could be protective factors for adolescents to reduce mobile SNS cyberbullying. However, adolescents' characteristics including aggression, depression, and delinquent peers were positively associated with adolescents' experiences of mobile SNS cyberbullying. This study highlights that various environments are closely related to adolescent development.

Although the Internet has been a important communication tool in modern societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the Internet may reflect their personality. To fill the research void like this, this study proposes a new research model in which well bing as well as perceived value are positively linked to satisfaction and continuance to use. The statistical results obtained by applying PLS to the valid 150 questionnaires showed that the well bing has stronger positive influence on satisfaction and continuance to use than the perceived value. Therefore, a practical implication is suggested that the web site need to be designed in a way of arousing users' well bing more strongly.

최근 들어 소셜 네트워크 사이트가 많아지면서 사용자들은 선택의 폭이 넓어졌다. 그리하여 다른 소셜 네트워크 사이트로의 이동이 쉬워짐으로서 소셜 네트워크 프레임을 구성하는데 충성도 개념이 중요하게 인식되기 시작하였다. 그러나 소셜 네트워크 분야에서 충성도의 연구는 아직 미묘한 수준이다. 전자상거래시대의 웹사이트 충성도는 사이트의 만족도와 신뢰성을 기반으로 개발되었다. 그러나 소셜 네트워크 사이트의 특성상 회원들의 충성도를 측정하기에는 어려움이 많다. 본 연구에서 우리는 소셜 네트워크 사이트의 서비스 품질 향상을 위한 잠재적인 회원을 찾을 수 있는 회원 충성도 평가 RFM모델을 제안하고자 한다. 그리고 개선된 RFM모델을 실제 사례에 적용하여 분석하고 그 일련의 과정을 기술하였다. 이는 연구 제안모델을 실제 비지니스에서 적용할 수 있다는 것을 제시함으로서 논문의 실용성을 높이고자 하였다.
