Objectives: This study was to measure community capacity using individual-level and organizational-level capacity indicators and illuminated the relationship of community capacity and self-rated health status in two regions in Seoul, Korea. Methods: The data from individual surveys were obtained by quota sampling the residents of two autonomous gu in Seoul (N=1,000). The data from organizational surveys were obtained by snowball sampling lists of organizations in the possession of gu offices with a sampling frame (N=153). The survey tools were 6 indicators regarding residents' social capital and a sense of community and 5 indicators regarding community-based organizations and their networks. The analysis methods consisted of the effect of the components of capacity on health status and social network analysis. Results: As for capacity on individual levels, while D-gu was mainly developed inn individual capacity in terms of social interaction, Y-gu was stronger in a sense of community and cohesion among residents. As for capacity on organizational levels, Y-gu was more developed than was D-gu in associational networks. Conclusion: It is necessary to develop health promotion program per community and to strengthen partnerships with and among grassroots organizations based in local communities through the measurement of community capacity.

Information and Communication Technology (ICT) has become a vital instrument for delivering a number of services such as education, healthcare and public services. Community wireless networks are community-centric telecommunication infrastructure developed to provide affordable communication for those who live in remote areas. This chapter discusses the role of Nepal Wireless in achieving socio economic development of rural communities by facilitating affordable Internet access. We analyze the challenges Nepal Wireless faced and articulate on the approaches it took to address those challenges such as lack of technical skills, appropriate technology and funding, difficult geographical terrains, unstable political situation, and expensive devices. In addition, we address the success and failure factors of this community-based ICT4D approach in order to guide similar endeavors. We conclude the chapter by some suggestions for policy makers, community developers, and academicians.

This study identifies the necessity and importance of innovation in rural communities and highlights the role of rural revitalization support centers in facilitating the diffusion of community innovation. The study provides a literature review and employs the survey method to verify the arguments. There is an urgent need for rural communities to be distinct, attractive, and competitive in the wake of globalization. It is clear that they must recognize the need to facilitate innovation under growing trends toward trade liberalization, environment-oriented life styles, diversified consumer needs, and a knowledge-based society. The results provide support for the legitimacy of establishing rural revitalization support centers to help community leaders and local stakeholders develop their communities. More specifically, rural communities should employ R&D outcomes from diverse fields and capacity building by community members, leaders, and local governments to foster sustainable growth by overcoming limitations in spatial access and resources. The results suggest that rural revitalization support centers can be established as intermediary organizations that can be operated to facilitate community innovation in rural development. In addition, these centers should play key roles such as empowering communities, facilitating region-specific rural development policies, motivating R&D applications for rural development, encouraging rural development networks. Further, close attention should be paid to facilitate mutual learning by expanding networks and interactions between these centers.

Wireless Body Area Networks (WBANs) have made it easier for healthcare workers and patients to monitor patients' status continuously in real time. WBANs have complex and diverse network structures; thus, management and control can be challenging. Therefore, considering emerging Software-defined networks (SDN) with WBANs is a promising technology since SDN implements a new network management and design approach. The SDN concept is used in this study to create more adaptable and dynamic network architectures for WBANs. The study focuses on comparing the performance of two SDN controllers, POX and Ryu, using Mininet, an open-source simulation tool, to construct network topologies. The performance of the controllers is evaluated based on bandwidth, throughput, and round-trip time metrics for networks using an OpenFlow switch with sixteen nodes and a controller for each topology. The study finds that the choice of network controller can significantly impact network performance and suggests that monitoring network performance indicators is crucial for optimizing network performance. The project provides valuable insights into the performance of SDN-based WBANs using POX and Ryu controllers and highlights the importance of selecting the appropriate network controller for a given network architecture.

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.

This study explores the gender differences in the relationship between social support, social networks and drinking behavior and illustrates gender differences in drinking behavior in order to provide evidence in planning a community health promotion program. Data was collected from 444 surveys (Male=190, Female=244) from a total of 1,899 adult residents in 738 households in the "Y" Apartment Complex in the Gangnam area of Seoul, Korea. Results show significantly higher rates of drinking frequency and alcohol consumption volume in males. Women with high-risk drinking behavior have fewer social relationships than women with normal drinking behavior. Within social networks, friends were significantly associated with drinking behavior and alchol abuse. Drinkers had more friends than non-drinkers in both genders. However, in association with alchol abuse, while male abusers had less friends than normal male drinkers, women abusers had more friends, indicating women who have drinking problems have a stronger social network. This pattern suggests gender differences in the association between social networks and alchol abuse. Therefore in approaching drinking issues, social support and social networks act as a key factor. For men, alcohol prevention programs should be aimed at achieving healthy drinking behavior at the aggregate level including people in his social support and social network groups. For women, the priority is alchol abuse. More attention is required in revealing the context between female social networks and alchol abuse and in developing coping strategies other than drinking.

Social networking communities (SNCs) are media designed to facilitate social interaction using highly accessible and scalable publishing techniques. SNCs can constitute individuals' their own profiles in the online environment and share texts, images and photos in a variety ways. In other words, one of the other motivators is knowledge sharing. Various sites, such as Facebook, Orkut, MySpace, and Hi5 are categorized as SNCs. SNCs have become increasingly popular in recent years among youths, especially students, who use them to build social networks. This study examines whether this usage of SNCs inculcates a sense of community among their members. Several studies have examined the role of a sense of community through increased usage in the context of virtual communities. Although this result may be true of virtual communities, this paper contends that the opposite relationship prevails in the case of SNCs because members interact to build networks and are not obliged to interact. The results reveal that maintaining long-term interactions in the SNCs is helpful in building a sense of community in SNCs. Although short-term usage may not boost the development of a sense of community in SNCs, it does matter if the premise is for a long-term commitment to SNCs. Implications for theory and practice are discussed.
