새로운 웹 정보를 얻기 위해 웹 사이트에 빈번히 방문하는 것은 시간 낭비이며 비효율적이다. 이러한 문제를 해결하기 위해 사용자가 웹 사이트의 정보를 인터넷으로 정기 구독하는 웹 신디케이션 기술이 최근에 도입되었다. 이를 통해 사용자는 웹 사이트에 대한 낭비적인 네비게이션을 하지 않고도 비교적 빠른 시간 내에 최신 정보를 획득할 수 있다. 그러나 현재 웹 신디케이션 기술은 주로 PC 환경에서 구현 활용되고 있기 때문에 이동성에 대한 고려가 되어 있지 않다. 본 논문에서는 웹 신디케이션 기술을 모바일 단말기와 모바일 인터넷으로 확장하는 시스템을 제안한다.

Social cost has been increased by traffic accident and congestion since early 1990s. The construction of roadways and railways has been suggested as countermeasures. However, ITS has finally introduced as a logical solution because the expenses of infrastructures are costly. The data collection field has developed through numerous researches and pilot projects. However the information provision field does need a lot of study. The traffic information broadcasting whether simple traffic information or the value-added information has been available via radio, television and internet which does not require tremendous investment compared with data collection stage. Therefore, this study reviews the suitability of the gadget service usually offered by window vista users which is the result of the development of technology and the changes of internet environment. It also suggests to using the RSS(Really Simple Syndication) manner as a basic method to provide the traffic information based on the needs of user in order to enhance the usability of traffic information. For this, this study analyzes the current methods and techniques of traffic information service which is widely available by local governments and companies and suggest possible changes and methods in order to provide Gadget-based service to the public.

The objective of the study which it analyzes the result which goes made to the equity investor venture company IPOs stock of Korean venture capitalists. The sample company is the venture business 101 which IPO time venture capitalists invest in period KOSDAQ market from 1997 July 1st to 2006 June 30th for 9 years. The result of the study was as follows. First, it is found that syndication investing venture capitalists than the sale investing venture capitalists has desirable investment act which relax non-symmetry information between the publicly held company and the investor. The study support to Bygrave(1987), Lerner(1994) and so on. Second, The venture capitalists under postscript investing the venture business compared to under investing shows IPO excess benefit rate initially more highly from the venture business and the investor whom already invests early stage prove to use the manned it exaggerates the value of the venture business which venture capitalists oneself invests from postscript phase through the high position characteristic At last, it is discovered that the investment equity ratio of venture capitalists effect of sound (-) postscript investor IPO result which analyzed. It is showed that venture capitalists will remain more lowly excess benefit rate as the equity ratio which the venture capitalists invests at the venture business will be high.

e-learning은 교육의 새로운 패러다임으로 각광받고 있다. 하지만 일방적인 강의식 교육으로 학습자의 참여도와 만족도등의 문제점이 있다. 또한 시스템 구축과 콘텐츠 제작 비용에 많이 투입되지만 효과성이 낮다는 지적이 있다. 이에 본 논문에서는 웹 2.0의 기술을 활용하여 기존의 문제점을 해결하는데 목적이 있다. 웹 2.0의 기술 중에 본 연구에 활용할 기술은 RSS와 위키이다. RSS는 웹 사이트의 콘텐츠를 공유하고 주고받을 수 있도록 만든 표준이다. 콘텐cm들 중에는 학습 자료로 추가 비용 없이 활용할만한 것이 많이 있다. 위키는 구성원간의 지식공유가 효율적으로 이루어 질수 있는 기능을 제공한다. 학습자들의 상호작용을 높힐 수 있는 도구이다. RSS와 위키를 접목하여 학습 시스템을 설계 및 구현하였다. 적용결과 기존 e-learning을 사용하여 학습한 집단보다 창의적 글쓰기에 RSS와 위키를 활용하는 학습 시스템이 학습에 더욱 효과적이라는 것을 보였다.

SDI(Selective Dissemination of Information) is on demand service to inform to the user applies a service after inputting a search strategy, when new information is obtained. This Paper propose the ways to develope the dynamic RSS channel generator for supporting SDI service. The RSS which is a kind of syndication technology enables a part or the whole of the content which it provides from web site to be able to be used in different service. It is protocol to summarize and share various contents on web site. Also, the users register the channel RSS to the RSS aggregator system and recommend it. It can drive to share of knowledge between researchers.

The personal image information compiled through closed-circuit television (CCTV) will be open to the internet with the technology such as Long-Tail, Mash-Up, Collective Intelligence, Tagging, Open Application Programming Interface (Open-API), Syndication, Podcasting and Asynchronous JavaScript and XML (AJAX). The movie User Created Contents (UCC) connected to the internet with the skill of web 2.0 has the effects of abuse and threat without precedent. The purpose of this research is to develop the institutional and technological method to reduce these effects. As a result of this research, in terms of technology this paper suggests Privacy Zone Masking, IP Filtering, Intrusion-detection System (IDS), Secure Sockets Layer (SSL), public key infrastructure (PKI), Hash and PDF Socket. While in terms of management this paper suggests Privacy Commons and Privacy Zone. Based on CCTV-UCC linked to the above network, the research regarding personal image information security is expected to aid in realizing insight and practical personal image information as a specific device in the following research.

OPAC is a very important interface for user to use and search library collection and electronic resources. The purpose of this study is to analyze empirically the impact of OPAC usability on user satisfaction and loyalty in an university library setting. The OPAC functions investigated are keyword searching, integrated searching, faceted navigation, relevance ranking, spelling check, recommendations, user participation, and Really Simple Syndication(RSS), etc. This study investigated what usability effects on user satisfaction and loyalty and suggested the way to improve user satisfaction and loyalty.

RSS is the XML-based format for the syndication of web contents, and users aggregate RSS feeds with RSS feed aggregators. In order to effectively aggregate RSS feeds, an RSS aggregation policy is necessary. In this paper, we first propose an aggregation policy to minimize the number of postings being missed within an aggregation. Second, we analyze and compare our aggregation policy with existing aggregation policies. Our analysis reveals that our aggregation policy can reduce approximately 23% of the aggregation missing in comparison with the other aggregation policies while it increases only 6% of the aggregation delay.

Coupled schemes between service-oriented architecture (SOA) and Web 2.0 have recently been researched. Web-based content providers and telecommunications company (Telecom) based Internet protocol television (IPTV) providers have struggled against each other to accommodate more three-screen service subscribers. Since the advent of Web 2.0, more abundant reproduced content can be circulated. However, because according to increasing device's resolution and content formats IPTV providers transcode content in advance, network bandwidth, storage and operation costs for content management systems (CMSs) are wasted. In this paper, we present a user centric CMS for open IPTV, which integrates SOA and Web 2.0. Considering content popularity based on a Zipf-like distribution to solve these problems, we analyze the performance between the user centric CMS and the conventional Web syndication system for normalized costs. Based on the user centric CMS, we implement a social Web TV with device-aware function, which can aggregate, transcode, and deploy content over social networking service independently.

This study investigates the relationship between venture capital (hereafter, VC) syndicate diversity and the IPO performance of an entrepreneurial company backed by the syndicate. Specifically, focusing on three types of diversity within a VC syndicate, which are aligned with Harrison and Klein's seminal categorization in 2007 (i.e., separation, variety, and disparity), this study suggests their distinct effects on performance. Two stage least square analyses with 1,127 VC syndicate investments made by 6,268 VC firms strongly supported the hypotheses. The results showed that that capacity diversity decreases the performance and that expertise diversity and network diversity increase it.
