This study aims to verify the mediating effect of social support in the relationship between online social relations service utilization(PC, mobile) and life satisfaction for middle-aged and Older Adults. For this purpose, the '2017 Digital Devide Survey' data collected by the National Information Society Agency was used, and among 2,300 middle-aged and Older Adults aged 55 or older, 1,488 people using the Internet were selected as the final analysis target. Then, using the structural equation, the mediating effect of social support was verified in the between online social relations service utilization and life satisfaction. As a result, it was verified that higher levels of mobile-based social relations service utilization have a positive effect on social support and life satisfaction. Also, it was confirmed that social support has a mediating effect in the relationship between the utilization of mobile-based social relations service and life satisfaction. However, the utilization of PC-based social relations services did not show to affect social support and life satisfaction. Therefore, the results of this study can be used as basic data for practical measures to increase the connection between mobile-based social relationship service education and social support promotion education for middle-aged and Older Adults. In addition, the study is meaningful in that it overcomes the limitations of measuring the use of online social relations services as one, and selects tools that are practically effective by dividing them into mobile and PC.

최근 Web 2.0 발달과 더불어 블로그나 온라인 카페 등 웹 상의 사용자가 개인적인 정보를 자유롭게 개제할 수 있도록 하는 인터넷서비스가 증가하면서, 이 사용자들 간의 관계에 초점을 맞춘 소셜 네트워크 분양의 연구가 활발히 이루어지고 있다. 하지만 많은 소셜 네트워크 서비스가 정보자원을 컴퓨터가 처리할 수 있는 의미적인 정보로 표현하고 있지 않기 때문에 서로 다른 도메인 간에 공유와 재사용이 어렵고, 사회적 개체들 간의 관계가 명확하게 정의되어 있지 않아 소셜 네트워크 분석에 어려움이 있다. 본 논문에서는 가상 커뮤니티 사용자들이 업로드 한 사진 데이터를 이용한 시맨틱 웹 기반의 소셜 네트워크 분석 시스템을 제안한다. 온톨로지를 기반으로 사진에서 추출된 얼굴 개체와의 관계와 이미 인맥 관계를 형성하고 있는 사람들의 정보적 연결성을 명확하게 정의하고 도메인 규칙을 활용하여 의미 있는 사회적 연결 관계를 추론한다. 이를 그래프로 시각화하여 사용자에게 제공함으로써 온라인 상에서 형성된 커뮤니티 내에서 효율적인 소셜 네트워크 분석을 도모하고 이를 기반으로 다양한 응용 분야에 활용하는 방법을 모색한다.

This research analyzed how smart devices and Social Network Service (SNS) change the construction of social capital. The results show that smart devices provide the foundation of expending 'bridging social capital' by offering various communication tools. SNS reinforces 'bonding social capital' and extends 'bridging social capital' by expanding social relationships from off-line to online and supporting the construction of online communities. In contrast, the use of SNS through smart devices is not related to the generation of social capital. However, it builds a multi-aspect social capital by making people participate in various social activities.

In this paper, the correlation which is at work between affecting factors and interpersonal relationships' dimension depend on developmental level has been studied to search for clues about how to develop the online based interpersonal relationships -the fundamental aims of SNS related services- efficiently. People who'd ever entered into a relation through the 'online-based generated relationship' by SNS were divided into two groups on the development level. They were conducted a survey, and the results were derived using PLS statistics. As the result, 7 kinds of factors as social attraction, physical attraction, reciprocity, content quality, coexistence perception, information provision and similarity had an impact on the initial level of relationships, and 6 kinds of factors as social attraction, physical attraction, reciprocity, content quality, web appearance and coexistence perception had an impact on the developed level of relationships. This study could be utilized for the service design for facilitating interpersonal relationships efficiently by their level of development.

1990년대 중반이후 정보통신의 발달에 의한 인터넷의 활용이 전세계적으로 급속히 팽창하면서 사이버마켓이라는 새로운 시장형태하에서 전자상거래가 급속히 성장하고 있다. 인터넷 전자상거래의 성장은 기존의 유통구조를 오프라인으로부터 온라인으로 전환시키고 물류체계까지 변화시키고 있다. 전자상거래의 경우 인터넷과 같은 정보시스템의 발달에 의해 독자적으로 성장할 수 있는 것은 아니며, 실제거래를 위한 물류와 연계해서만이 가능하다. 따라서 전자상거래의 급속한 성장과 더불어 문전배송서비스(door-to-door delivery service)가 가능한 택배서비스가 급속히 증가하고 있다. 이러한 관점에서 도시내에서의 전자상거래에 의한 택배서비스시장 환경변화를 고려하여 전자상거래를 촉진시키는 어떤 요인이 택배서비스에 영향을 미치고 성장에 중요한 역할을 하는지를 파악해 보는 것도 흥미있는 일이라 하겠다. 본 연구는 시계열데이터를 이용하여 전자상거래에 의한 택배서비스시장의 상관관계를 검토하고 전자에 의한 후자의 성장요인을 분석해 보는데 그 목적이 있다. 본 연구에서는 택배서비스시장의 성장요인을 시장내부의 내적요인과 외부의 외적요인으로 구분하고, 외적요인을 다시 교통요인과 사회경제적 요인으로 구분하여 전자상거래를 사회경제적 요인으로 간주하였다. 그리고 이 사회경제적 요인으로서의 전자상거래에 의한 택배서비스시장의 인과관계성을 그랜저-심즈(Granger-Sims) 인과관계검정을 이용하여 분석하였다. 분석결과, 한국의 전자상거래는 EDI(전자문서교환)도입업체수, 인터넷 쇼핑몰수, 인터넷 이용자수, 전자상거래를 위한 법제도 체계 등의 증가에 의해 촉진되었으며, 이에 따라 택배서비스시장도 성장한 것으로 나타났다. 특히 정부주도에 의한 정보화추진이 전자상거래를 촉진시켜 택배서비스시장에 영향을 미친 것으로 분석되었다.

Recently, one of the received attraction fields in web based service is 'Human Relationship Service' that is called SNS. This relationship map service is able to deliver information to user more easily and visually because it is intuitive data that is linked with offline real world. While past map service put physical real information in the map, present map service is evolving into new communicative platform that expresses social relationship beyond simple search platform that shows real world. In this paper, we propose smart social grid system using sketch map that is based on online map service structure. This system has features such as standardized interface provision for various SNS, use to governance hub tool in case of establishing a personal network through expanded social grid, a role of bridge to mashup software linked with other SNS, user environment construction that reproduces social grid data, and the faster service setup by improved search technology.

In recent decades, China's economy has grown rapidly and two-dimensional bar code-based payments services have been activated. This is a model that will be introduced by developing countries that lack mobile payment infrastructure, and countries that are looking to leap into cashless societies are also drawing attention. Along with this, the existing CRM market is expanding around the mobile device called m-CRM, and research is active on the importance of collective use for online advertising and two-dimensional bar code-based payments services. Therefore, through this study, we have explored the concepts and status of online advertising and customer relationship management which using the two-dimensional bar code-based system, and designed and implemented the method and mobile application system to effectively disseminate transactional advertising information at the point of sale or at the point of share. We also presented an application approach to look at the direction of two-dimensional bar code-based ads contents sharing system and its development.

The current paper aims to analyze the influence of users' self evaluation of e-service quality and others' word-of-mouth(WOM) on customer satisfaction and revisit intention in a family restaurant web site. The research model includes the constructs of service quality, WOM, customer satisfaction, and revisit intention. This study examines the hypothesized model using data from 175 college students around the Seoul metropolitan area who have visited a family restaurant as well as used its web site during the last three months. The findings show that service quality has a significant impact on customer satisfaction and a full-mediation effect between WOM and customer satisfaction. In addition, customer satisfaction has a significant influence on revisit intention. Family restaurants need to have an effort to manage service quality factors and social influences such as online WOM in order to use a web site as a tool of customer relationship management.

With the growth of Web 2.0, lots of services allow yours to post their personal information and useful knowledges on networked information spaces such as blogs and online communities etc. As the services are generalized, recent researches related to social network have gained momentum. However, most social network services do not support machine-processable semantic knowledge, so that the information cannot be shared and reused between different domains. Moreover, as explicit definitions of relationships between individual social entities do not be described, it is difficult to analyze social network for inferring unknown semantic relationships. To overcome these limitations, in this paper, we propose a social network analysis system with personal photographic data up-loaded by virtual community users. By using ontology, an informative connectivity between a face entity extracted from photo data and a person entity which already have social relationships was defined clearly and semantic social links were inferred with domain rules. Then the inferred links were provided to yours as a visualized graph. Based on the graph, more efficient social network analysis was achieved in online community.
