The existing mashup service providers have induced users to participate in their own made services and have grown their services by user participations and contributing contents. Recent services based on Web2.0 are called by 'Open (Content) Service' which means anyone can provide new services to the others without any of their own contents. But unfortunately the most of these days services are not opened. They just using mashups for increasing their service's traffics. We introduce the way to make a simple service to provide searching videos present it with extracted keyword from external content without our own contents at all. this show that how to combine the content with another contents or services.

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.

The prototype of forest fire management system on Web was studied. In the architecture of this system, one of the most important concerns is to handle load upcoming to Web Server so that it provides Web service without any delay or failure. In order to solve this problem, the agent is designed on dispatcher in a Web server cluster and implemented to distribute load dynamically by considering the information related to load coming to the Web Server such as the number of connection to the Map Server. The proposed forest fire management system has user-friendly interface with the GIS mapping functionality by selecting Map Objects Internet Map Server (MO IMS) as Map Server and is implemented using Java as programming language.

Company A's core competency is IT internet security services. The Web diagnosis team analyzes the vulnerability of customer's internet web servers and provides remedy reports. Traditionally, Company A management has utilized a simple table format report for resource planning. But these reports do not notify the timing of human resource commitment. So, upper management asked its team leader to organize a task team and design a visual dashboard for decision making with the help of outside professional. The Task team selected the web security diagnosis practice process as a pilot and designed a dashboard for performance evaluation. A structural design process was implemented during the heuristic working process. Some KPI (key performance indicators) for checking the productivity of internet web security vulnerability reporting are recommended with the calculation logics. This paper will contribute for security service management to plan and address KPI design policy, target process selection, and KPI calculation logics with actual sample data.

인터넷은 우리에게 많은 정보를 제공해 주는 중요한 수단이 되었다. 그리고 정보 제공을 위해 인터넷의 서버 시스템들은 대용량의 정보를 처리하여 다양한 서비스를 제공함과 동시에 이들의 네트워크 구조는 더욱 더 복잡해지고 있다. 따라서 서버 시스템들에 대한 신속하고 지속적인 관리가 중요시 되고 있다. 그러나 대부분의 서버 시스템들은 방화벽 내부에 위치하여 제한된 접근만을 허용하며 또한 각 서버 시스템들의 서로 다른 운영체제와 서로 다른 관리 방법으로 인해 효율적인 서버 시스템 관리가 이루어지고 있지 않다. 즉 서버 관리자들은 제한된 공간에서 로컬 또는 소켓 기반의 단일 접속 애플리케이션을 이용하여 다양한 형태의 서버들을 직접 관리해야만 한다. 따라서 본 논문은 CORBA, Java RMI, DCOM등의 분산 객체 기술을 가지면서 플랫폼이나 개발언어에 제약을 받지 않는 XML(extensible Markup Language) 기반의 웹서비스 기술(Web Services Architecture)을 이용하여 다수의 서버 시스템들을 통합적으로 관리 할 수 있는 미들웨어 시스템을 설계하고 구현하였다. 시스템은 위치 투명성 및 단말기 독립성을 제공하며 서버 시스템 관리 명령을 호출하여 시스템 관리가 가능하다.

영상기록물은 최근 많은 이용자들이 선호하는 매체이며, 방송영상이 중요해짐에 따라 이용 요구도 많아지고 있다. 그러나 현재 국내 대다수의 방송사 아카이브 기관들은 내부 직원을 위한 아카이브 서비스를 제공하고 있을 뿐, 일반 대중들을 위한 적극적인 기록정보 서비스를 제공하고 있지 않다. 이 연구에서는 특히 해외 공영방송사 아카이브 사이트에서 일반 대중을 대상으로 제공하는 온라인 기록정보서비스를 살펴보고 국내 방송사 서비스의 개선방안을 제시해보고자 하였다. 이를 위해 온라인 접근성, 검색 및 온라인 열람 그리고 아웃리치(확장) 서비스라는 3가지 서비스영역의 기준을 설정하고, 이에 의거하여, 각 영역별로 해외 공영 방송사의 서비스를 살펴보고 분석하였으며, 국내 공영 방송사 현황을 살펴보았다. 이를 바탕으로 국내 공영방송사에 대한 일반 대중들을 대상으로 한 온라인 검색 및 자료의 제공, 다양한 아웃리치 서비스의 개발, 이용층의 확장 등, 기록정보서비스 개선 방안을 제시하였다.

본 연구에서는 기록관 웹사이트의 검색어 분석 결과를 이용자들에 대한 기록 정보서비스에 효과적으로 활용할 수 있을지 알아보고자 하였다. 특히 검색어 분석을 콘텐츠서비스 등 기록정보서비스 개발의 한 방법론으로 검토해보고자 하였다. 이를 위해 공기록관이자 주제기록관으로서 일반 이용자들의 폭넓은 관심을 끌만한 특징을 가지고 있는 대통령기록관의 검색어 데이터를 수집하여 분석하였다. 대통령기록관의 웹사이트 검색어 분석 결과는 (1) 일반 검색어 분석; (2) 대통령 이름별 분석; (3) 검색어 주제 영역 분석 등 세 가지로 제시되었다. 검색어 분석 결과는 콘텐츠서비스 및 웹사이트 메뉴 설정, 전시, 교육 등 다양한 서비스에 실질적으로 활용될 수 있을 것으로 판단되었다.

The Semantic Web is an evolving extension of the WWW in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content. The sementic web relied on the ontologies that structure underling data for the purpose of comprehensive and transportable machine understanding. The Semantic Web relies on the ontologies that structure underlying data for the purpose of comprehensive and transportable machine understanding. And recommendation systems have been developed as a solution to the abundance of choice people face in many situations. This paper shows that the new recommendation method is suitable for effective recommendation on the semantic web. We present a new procedure for improving the effective recommendation by using the levelized context ontology. Our experimental results also confirm that our method has good recommendation time. Our proposed method can be generalized to fit other application domains.

Providing a secure 3-tier Web application has become a high priority for companies as e-businesses have increased the amount and the sensitivity of corporate information that can be accessed through the web. Web applications become more difficult to secure with this very increase in online traffic and transactions. This paper first reviews the 3-tier of web application, types of attacks that can threaten web application services and security principles. We then are designing and implementing a secure web application with open source software that able to mitigate the web application vulnerable to attack.

In high education, knowledge is the very important resource and output. Knowledge management is the art of creating additional value from academic knowledge assets. The e-community is the network community, newly created by information communication technology, and the critical place that share and transfer people's the various knowledge and thinking and the effective space that can apply knowledge management. If we construct a convenient and useful e-community in our university, we will be able to increase the student's intellectual needs, and create new knowledge. Web-portal will promote the activity of e-community providing easy to access and personalized web circumstance. The emergence of Internet and Web access to all university services will force institutions to rethik everything. We should reconfigure our academic environment in order to adapt information technology and educational change, and must do change management based on their structure and culture.
