인프라스트럭처 상용 클라우드 서비스(IaaS)의 이용 시 클라우드 기반의 네트워크에 어떤 정보보호기술을 적용할 지에 대한 고려를 하는 것은 기존의 네트워크에 정보보호기술을 적용하는 것과 차이가 있다. 그 차이점은 클라우드 서비스 사업자가 서비스 형태로 제공하는 정보보호 기술들을 선택하여 적용할 수 밖에 없다는 것이다. 본 연구는 사업자가 제공하는 정보보호 서비스들이 어떠한 것이 있는지를 분석 종합하고, 기술의 특성을 고려해 재분류하고, 기업별로 제공되는 정보보호기술의 적용에 드는 비용을 함께 조사하여 각 사업자들의 정보보호기술의 과금 형태를 분석하였다. 또한, 이러한 분석을 기반으로 게임, 의료 및 소셜 커뮤니티 사이트 등의 기업 유형별 필요 기술을 선택하는 시나리오 분석을 시도 하였다. 본 연구의 기여점은 클라우드 환경에서의 정보보호 기술의 분석을 통해 해당 기술을 적용하고자 하는 사람들이 어떻게 기술을 선택 및 적용 할지에 대한 실질적인 방법을 제시한 것에 있다.

TV has also been a possible SSN market to draw users to share interests and participation. However TV has been always community electronics in family members and personalization to provide SNS has been barrier to overcome. In this study, we explorer ideas of key factors of personalization in TV environment and conducted a field study to define characteristics of TV personalization in terms of depth, method, style and structure.

This paper examines the rising value of social networked journalism and analyzes the case of a social news site based on the theory of networked journalism. Social networked journalism allows the public to be involved in every aspect of journalism production through crowd-sourcing and interactivity. The networking effect with the public is driving journalism to transform into a more open, more networked and more responsive venue. "wikitree" is a social networking news service on which anybody can write news and disseminate it via Facebook and Twitter. It is operated as an open sourced program which incorporates "Google Translate" to automatically convert all its content, enabling any global citizen with an Internet access to contribute news production and share either their own creative contents or generated contents from other sources. Since its inception, "wikitree global" site has been expanding its coverage rapidly with access points arising from 160 countries. Analyzing its international coverage by country and by news category as well as by the unique visit numbers via SNS, the results of the case study imply that networking with the global public can enhance news traffic to the social news site as well as to specific news items. The results also suggest that the utilization of Twitter and Facebook in social networked journalism can break the boundary between local and global public by extending news-gathering ability while growing audience's interest in the site, and engender a feasible business model for a local online journalism.

본 논문에서는 문헌연구를 바탕으로 SNS가 갖추어야 하는 바람직한 요인으로서 시스템특성, 서비스특성, 정보특성, 감성특성을 도출하는 동시에 이러한 SNS의 특성과 만족도간에 어떠한 관련성이 있는가를 실증적으로 파악하고자 했다. 또한, 이러한 SNS의 특성과 만족도간의 관련성이 응답자의 국가유형에 따라 달라지는가를 분석하고자 하였다. 본 연구의 목적을 달성하기 위하여 한국과 중국의 인터넷 사용자들을 대상으로 설문지 분석을 실시한 결과, SNS의 여러 가지 특성들이 SNS 만족도에 통계적으로 유의한 수준에서 긍정적 영향을 미치고 있음을 알 수 있었다. 또한, SNS의 특성과 만족도간의 관련성이 국가유형에 따라 차이가 존재하고 있음을 확인할 수 있었다.

사람의 피부는 개인마다 상태의 차이가 있으며, 개인의 피부 상태에 따가 피부고민도 다르다. 이에 따라, 일반 소비자들의 화장품 사용에 대한 선호도는 나만의 것, 내 피부에 맞는 화장품, 자세한 카운슬링 순으로 선호도가 나타나고 있다. 민간기관에서도 유전자 검사가 가능해짐으로써 상기와 같이 피부에 대한 유전자 분석도 활성화되고 있는 실정으로, 본 논문에서는 개인의 피부 유형과 유전자 정보를 고려하고 소셜 네트워크에서의 데이터를 수집하여 빅데이터 분석을 통한 맞춤형 추천 서비스를 제안한다.

Especially, various human, social and spatial characteristics can be observed through geolocation data and social data collected through mobile GPS, and it is used in various studies. In this study, we analyze the social data collected through the image - based vertical SNS Instagram, and measure the user 's experience based on the social media based on the user' s spatial context.

Social Network Service(SNS) have become very popular during the past few years. Also SNS, an current communication platform, greatly contributes to transmit the information rapidly and strengthen a sense of community and fellowship in military service. however it has vulnerable factors. For example, invasion of privacy, exposure of personal information and military data. In this particular case, it is a deathblow to the military service. Military Social Network Service require to protect the military security threats and disclosure of defense secrets.

People use various tools to present themselves including Social Network Services(SNS hereafter). This study categorized three types of presentation of self, which are genuine, ideal, and social self, and based on Goffman's Impression Management Framework, investigated if these types of presentations have any patterns related to SNS posting styles. Especially, we focused on the styles of hashtags including if hashtags are used in the main tests, if hashtags are hidden, and what kinds of words are used for hashtags. Using 450 posting data uploaded to the Instagram, we found that the posting presenting ideal self show very high rate of using hidden hashtags(98%) and using common expressions(97%), which are not the case for genuine and social self types. This results imply that people concern more about their impressions especially when they present their ideal self on SNS, partially confirming Goffman's Impression Management Framework.

Recently, many user-participating web services have been used widely as the evolution of internet web technology has rapidly been developed. Users share various content and opinion on line using a site like ‘Social bookmarking.’ Users can share others’ bookmarking history and create tags while bookmarking web sites; we call it collaborative tagging. In this paper, we studied empirical analysis for widely used social bookmarking and collaborative tagging which the result shows minority of users is actively using the bookmarking and a few sites and tags are used by majority of the users. 24% users tagged 80%, 75% sites and 81% tags were tagged below than 3 times. Types of bookmarking activities were found different by users and early appointed tags get more frequency by majority. We also identified relative proportions of tags on certain sites are becoming convergence gradually. We expect the result of this paper will give opportunities to help further developing social bookmarking system.
