Considering the continuous increase of teenagers' Internet use and the high rate of their participation in online communities, educators need to devote efforts to minimize the negative function of teenagers' Internet use and to guide them to experience positive aspects of Internet. Through activities in online communities, teenagers can experience various socialities and explore their self-consciousness. However, on the other hand many communities do not provide teenagers with considerate care. This may cause conflict in their sense of value and mislead them. Through this study, online learning community is designed and developed, which can reflect teenagers' various needs and connect their needs with learning experiences. The community consists of the following categories: 'about e-Tivity'(community vision, general information, list of activities, Q&A), 'activity space for teens'(event hall, data park, e-Tivity center), 'administrative space for teachers and managers'(research room, management room), and 'teen's private space'(my room, my avatar).

'Enhanced Cooperation', which was the mandate of Tunis Agenda in 2005, was the product of political compromise after failing to reach a consensus on global internet governance mechanism. In 2012, UN General Assembly decided to establish CSTD 'Working Group on Enhanced Cooperation (WGEC)' to find out what could and should be done to implement the Tunis Agenda. After a first meeting, WGEC sent out a questionnaire to collect extensive opinions from internet communities. Replies to the questionnaire showed a broad spectrum of perspectives on the problem of existing internet governance arrangement and how to improve it. This article analysed different perspectives, based on replies, especially regarding the concept and implementation of the Tunis Agenda, public policy issue and possible mechanisms, and the role of stakeholders including government. The recommendation of WGEC will be submitted to UN GA passing through CSTD and ECOSOC, in 2014, which is expected to have great impact on the future of internet governance.

The purpose of this study was to clarify the factors that characterize the fashion brand online communities that have a high participation rate among high school students, and to determine the impact of those factors on the high school students' commitment to the community, especially in relation to their demographics. The study was implemented through a descriptive survey method using an online questionnaire. The sample consisted of 301 members of online fashion brand communities operated on the Daum portal site. The data were analyzed by frequency, factor analysis, and regression analysis. The results are as follows: (1) Factor analysis revealed that the characteristics of a fashion brand online community are associated with three factors ; compensation/interest, interactivity, and information. (2) Regression analysis showed that the more compensation/interest, opportunity for interaction, and information the community provides, the more likely high school student members are to show a higher level of commitment to the community. (3) There was no difference in the effect of community attribute factors on the high school student members' commitment to the community according to gender. The group of students majoring in human and liberal education was the most influenced by the attributes of fashion brand online communities. The interactivity factor had a greater impact on the group of students majoring in art and physical education than on the other groups. The greater the use of the Internet, the greater the impact of community attributes on commitment. (4) In the process of developing an online community, marketers should fully consider the fact that information factors have the biggest impact on high school students' commitment to the community. Therefore, greater effort should be made to differentiate between community attributes based on high school students' majors and their amount of Internet use in order to motivate commitment to the community and brand loyalty as well.

Online communities, such as Internet portal sites and social media, have become popular since they allow users to share opinions and to obtain information anytime, anywhere. Accordingly, an increasing number of opinions are manipulated to the advantage of particular groups or individuals, and these opinions include falsified product reviews and political propaganda. Existing detection systems are built upon the characteristics of manipulated opinions for one particular time period. However, manipulation tactics change over time to evade detection systems and to more efficiently spread information, so detection systems should also evolve according to the changes. We therefore propose a system that helps observe and trace changes in manipulation tactics. This system classifies opinions into clusters that represent different tactics, and changes in these clusters reveal evolving tactics. We evaluated the system with over a million opinions collected during three election campaigns and found various changes in (i) the times when manipulations frequently occur, (ii) the methods to manipulate recommendation counts, and (iii) the use of multiple user IDs. We suggest that the operators of online communities perform regular audits with the proposed system to identify evolutions and to adjust detection systems.

Many methods of discovering social networking communities or clustering of features are based on the network structure or the content network. This paper proposes a community discovery method based on topic models using a time factor and an unsupervised clustering method. Online community discovery enables organizations and businesses to thoroughly understand the trend in users' interests in their products and services. In addition, an insight into customer experience on social networks is a tremendous competitive advantage in this era of ecommerce and Internet development. The objective of this work is to find clusters (communities) such that each cluster's nodes contain topics and individuals having similarities in the attribute space. In terms of social media analytics, the method seeks communities whose members have similar features. The method is experimented with and evaluated using a Vietnamese corpus of comments and messages collected on social networks and ecommerce sites in various sectors from 2016 to 2019. The experimental results demonstrate the effectiveness of the proposed method over other methods.

Recently, with the advance of the wireless Internet access via mobile devices, a myriad of game development companies have forayed into the mobile game market, leading to intense competition. To survive in this fierce competition, mobile game developers often try to get a grasp of the rapidly changing needs of their customers by operating their own official communities where game users freely leave their requests, suggestions, and ideas relevant to focal games. Based on the heuristic-systematic model (HSM) and the data quality (DQ) framework, this study derives key content, non-content, and hybrid cues that can be utilized when game developers accept suggested postings in these online communities. The results of hierarchical multiple regression analysis show that relevancy, timeliness, amount of writing, and the number of comments are positively associated with mobile game developers' knowledge adoption. In addition, title attractiveness mitigates the relationship between amount of writing/the number of comments and knowledge adoption.
