Web 2.0 is a platform which produce various service offered data from many people and it is activity open space depend on user focused community in diversity web environment. Web 2.0 is simple link structure with web site connectivity in informations such as page to page in other words, it is meaning of developing of semantical and circumstantial connection. The core of web 2.0 is user participation. RSS, Mash-up, UCC are main service of web 2.0 which make user directly participate from center of service offer to center of user manufactured an informations and then they offer re-information to other areas, also user freely express what they want through UCC and blogger. However, recently it comes the argument of skeptic of web 2.0 problem. Thus, In this research I will try to give an right comprehension and will try to have more accurate prediction of web 2.0 with the study of open service of web which is the key of web 2.0 success in a future.

Web 2.0기술이 출현함에 따라 도서관 이용자들이 이미 웹상에서 다양한 기능들을 경험하고 있고, 이러한 경험들을 도서관 정보시스템에 요구하고 있다. 이에, 본 연구에서는 Web 2.0개념과 기술 및 Library 2.0, Catalog 2.0(OPAC 2.0) 개념들을 문헌고찰을 통해 이해를 높인다. 그리고 Web 2.0 기술이 적용된 대표 사이트들과 국내외 도서관 사이트를 분석하여 Web 2.0 기술 중 활용도가 높은 기술들을 분석한다. 마지막으로 분석된 내용을 토대로 향후 도서관의 정보시스템이 이용자 중심의 시스템으로 발전하는데 필요한 목록, 검색, 부가서비스 영역에서의 활용방안과 이러한 기술들이 적용됨으로 나타날 수 있는 부작용에 대해서도 함께 제시하였다.

We first develop a value ecosystem framework to model the SDP(Service Delivery Process) of web services. Since the web service has been evolving from the basic web architecture (e.g., traditional world wide web) to a prosuming platform based on virtualization technologies, the proposed framework of the value ecosystem focuses on capturing the key characteristics of SDP in each type of web services. Even though they share the basic elements such as PP(Platform Provider), CA(Customization Agency) and user group, the SDP in the traditional web services (so-called Web1.0 in this paper) is quite different from the most recent one (so-called Web2.0). In our value ecosystem, users are uniformly distributed over (0, ${\Delta}$), where ${\Delta}$��represents the variety level of users' preference on the web service level. PP and CA provide a standard level of web service(s) and prosuming service package, respectively. CA in Web1.0 presents a standard customization package($s_a$) at flat rate c, whereas PP and CA collaborate and provide customization service with a usage-based scheme. We employ a multi-stage game model to analyze and compare the SDPs in Web1.0 and Web2.0. Our findings through analysis and numerical simulations are as follows. First, the user group is consecutively segmented, and the pattern of the segmentations varies across Web1.0 and Web2.0. The standardized service level s (from PP) is higher in Web1.0, whereas the amount of information created in the value ecosystem is bigger in Web2.0. This indicates the role of CA would be increasingly critical in Web2.0: in particular, for fulfilling the needs of prosuming and service customization.

Web 2.0 which is characterized by openness, sharing with others and users' active participation has a strong impact on Individual and business environments. New technology such as open-API, RSS, collective intelligence gives various benefits to the website user. Recently, the Web 2.0 paradigm has also affected the public service. Many public service organizations are also adopting Web 2.0 applications to improve their ability for serving users more effectively. However, there is a contradiction between value of public service and that of web 2.0. Web 2.0 which pursues openness and freedom of expression can impair the accuracy and reliability of public information in the public sites. We conducted a case study on EBS which reflects the Web 2.0 strategy for websites renewal. To cope with environmental changes, EBS began reorganization of the web site and applied Web 2.0 strategy for leveraging an easy to use and user satisfaction. This research shows that how to Implement the Web 2.0 strategy and what is the limitation of it. The findings of this study suggest practical implications for Web 2.0 strategy in public web sites, especially for educational fields.

사회적 컴퓨팅(social computing)의 현상이 Web 2.0 공급사슬(supply chain)의 변화관점에서 새로운 변화의 단계를 맞이하고 있다. Web 2.0 플랫폼을 어떤 형태로 기업 활동에 활용할 것인가 하는 문제제기에 대하여 다양한 기업 활동의 변화사례가 발견되고 있다. 본 논문은 그와 같은 다양한 Web 2.0 환경 확산에 대한 기업 활동의 변화현상 중에서 Web 2.0 플랫폼을 기반으로 한 신제품개발(New Product Development) 사례연구를 통하여 진행한 결과를 반영하였다. 신제품 개발을 위한 플랫폼으로서 Web 2.0 의 협업적 환경을 설계하게 될 경우, 고객의 내재적 요구사항(latent requirement)이 제품개발에 효과적으로 반영될 수 있도록 하는 절차(process)가 기존의 제품개발방법론과 연관되어, 어떤 형태로 적용되고 개선되어 발전될 수 있는가에 대한 경험적 사례를 사례연구방법의 탐험적 경향을 활용하여 살펴보았다. 본 논문에서 다루어졌던 사례는 Web 2.0 플랫폼을 기반으로 사용자 창작 콘텐츠(User Created Content)를 생산하고 증가된 연세대학교 UCC의 양적 팽창에 의해서 수익모델이 발생하는 전형적인 Web 2.0 비즈니스 모델의 구조를 보여주는 경우였다. 본 연구를 통해서 사용자의 내재적 요구사향을 Web 2.0 기술특성을 통해서 참여적 사용자, 혹은 사용자 디자이너들의 적극적인 활동에 의해서 개선 및 구현해 가는 과정을 구체적 개발방법론의 틀로서 정착하려는 시도를 하였다.

After the beginning of Web2.0 era, newly developed interaction design patterns based on Ajax(Asynchronous JavaScript and XML) have been tried in various Web2.0 services. These new interaction design patterns enable web service to provide rich experience for users. However, it is very hard to find organized task based guideline about Web2.0 interaction design even though there are a lot of complicated interaction design techniques and patterns. It is essential to have Web2.0 interaction guide based on Ajax because it can guide designers to use appropriate interaction design patterns and to keep usability for ordinary users. Therefore, this research aims to establish task based interaction design guideline for Web2.0 service based on Ajax. The reason why this research focused on Ajax is that Ajax is most widely used language for Web2.0 service. First, primary five interaction design patterns were defined through analysis of various interaction design patterns from Web2.0 services. Second, detail interaction design tasks from five major patterns were analyzed based on the study of major Web2.0 services such as Gmail, Twitter, YouTube and Google maps. Third, general design guidelines such as heuristic guidelines for web service are studied through literature review. After all, this study proposed task based interaction design guide for Web2.0 service with Ajax. With this guide, designers and developers can choose appropriate Web2.0 interaction patterns and apply to their service and provide service to users with enhanced usability and satisfaction.

Government itself produces a vast amount of highly valuable information, and the internet increases its potential social and economic value. So far, government provide web services that is web 1.0 style. To meet the user's needs, that is online collaboration and sharing, government web services also change to web 2.0. This paper argues that government could now grasp the opportunities that are emerging in terms of web 2.0. Current policy and action is not yet adequate to grasp these opportunities. So, this study focused on the strategic development of electronic government services based on web 2.0. For the purpose, we reviewed the web 2.0 cases and former electronic government services. And then, we defined government 2.0 that is electronic government services based on web 2.0, and provided reference model of government 2.0. Government 2.0 reference model will help the administrators to find better ways to use the technological infrastructure and save efforts for trial and errors from the lack of systematic approach.

Progressing of Web2.0 and social digitalization are lead to changing citizens participation and citizen centric service of civic service. To meet this trends that is online collaboration and sharing, citizen's service that provides our government, also need to changing web2.0 style. This paper argues that government could now grasp the opportunities that are emerging in terms of web2.0 Current policy and action is not yet adequate to grasp these opportunities. So this study focused on strategies of civil services based on web2.0 using NCIA(National Computerization Integrated Agency) cases. For the purpose, we analyze former researches related with civil service. And then, we propose web2.0 adaptation strategies for NCIA.
