웹을 이용한 클라이언트-서버 데이타베이스 시스템은 웹의 서비스 능력과 데이타베이스 시스템의 데이타 관리 기능을 상호 보완적으로 통합함으로써 인터넷과 같은 대규모 환경에서 데이타베이스 업무 환경을 구축하는 데 매우 적합한 것으로 알려져 있다. 데이타베이스 통로는 이러한 통합의 가장 핵심적 구성 요소이다. 본 논문에서는 먼저 클라이언트-서버 데이타베이스 응용을 위한 데이타베이스 통로의 고려사항으로서, 고성능 실행구조, 응용 프로그램 개발 환경, 그리고 상태 및 트랜잭션 관리에 대해 기술하고, 이어서 UniSQL/X용 데이타베이스 통로인 UniWeb 2.0의 설계와 구현에 대하여 소개한다. UniWeb 2.0은 CGI 응용 서버 방식을 채택하여 다양한 플랫폼을 지원하고, 고성능 그리고 확장성을 제공한다. 또한 프로그래머가 HTML 문서에 SQL/X문장이 포함된 Tcl 스크립트를 끼워 넣을 수 있도록 하여 응용 프로그램 개발 생산성을 향상시키고 있다. UniWeb 2.0은 여러 웹 페이지에 걸친 상태 와 트랜잭션을 지원하고 있다.

This paper proposes an ontology population model based on ISO/IEC 11179. Much research has recently been done on harmonizing Web 2.0 and the Semantic Web, and the harmonization is defined as Web 3.0. The most important issues for realizing Web 3.0 include defining ontology schemas and populating instances for ontologies. To resolve the issue, Web ontology schemas should be precisely defined, and a method for populating Web ontology from Web resources should be developed. This paper proposes a Web ontology population model based on ISO/IEC 11179 - Metadata Registry (MDR), which is the international standard, developed to manage and use common standard concepts.

Recently, the Web 2.0 bas gained much attention as an advanced form of Web technology. It is well observed that openness, participation, and sharing are the key ideas of Web 2.0 among many desirable characteristics of the technology. Furthermore, Wiki is one of the best representing tools that reflect effectively most of the characteristics of Web 2.0. Wiki is widely used to provide a Web-based communication tool for collaborative writing and editing freely. Therefore, it may be used for collaborative learning so that students can learn how to interact online with each other effectively and also acquire communication skills in an affirmative way. In the paper, we will discuss how students can change their aggresive, offensive, judgemental attitudes to affirmative, aggreable, thoughtful ones by way of exposing them to collaborative learning environment using Wiki as their interactive communication tool.

Most people choose Internet search engine first more than the library for their information search in these days. Many users do not know library homepage's content. How to improve the users in library homepage? This study aims to suggest the direction of library homepage service in Web 2.0. For this study the author analyzed library homepage that is introducing some representative Web 2.0 and other Web 2.0 sites. AJAX, RSS, Open API, MashUp, Wikis, Blog are the main technologies in Web 2.0. Those technologies become a tool that can do user centered library homepage. But, more important thing is information production that introduce to users. Web 2.0 suggests good information transfer for users. It needs to produce the information that stimulates the library user. It means that Web 2.0 give a good opportunity for libraries as an information production.

Due to the progress of Bioinformatics field, We are making use of analyzing tools for effective analyzing enormous data of DNA sequence. But there was inconvenience in existing tools when searching and applying data for analyzing. Our treatise proposes a tool developed by a form based on RIA(Rich Internet Application) that you can solve the problems came from weak points. The analyzing tool for RIA indexing data of DNA sequence shows the results by real time in basis of Web 2.0 which supplemented basis on a form of Web. The web application was developed in Flex2 on Windows workstation.

Recently, the web 2.0 services which appear by exponential extension of the Internet can be expressed with the changes in the quality of structural evolution and in the quantity of increasing users. The structural base is in user participational architecture, the web 2.0 services such as Blog, UCC, SNS(Social Networking Service), Mash-up, Long tail, etc. play a important role in organization of web, and grouping and searching of user participational data in web 2.0 is broadly used by folksonomy. Folksonomy is a new form that categorizes by tags, not classic taxonomy skill. it is made by user participation. Searching based on tag is now done by a simple text or a tag cloud method. But searching to consider and express the relations among each tags is imperfect yet. Thus, this paper provides the relational searching based on tags using the relational graph of tags. It should improve the trust of the searching and provide the convenience of the searching.

The issue on cyber ethics cannot be solved within technical and legal boundaries. Therefore, this study intends to consider the antecedents affecting cyber ethics from the perspectives of individual characteristics and social influences. Specifically, the current research aims to investigate (1) the effect of individual characteristics(self-efficacy, locus of control) on cyber ethics in web 2.0 environment, (2) the impact of social influences(subjective norm, image, visibility) on cyber ethics, (3) the moderation effect of a user's personality(extroversion, introversion) between individual characteristics and social influences, finally (4) the interrelationship between cyber ethics and the type of web 2.0 service participation of users(consumption, production).

In the mid-2000s, Web 2.0 appears and is becoming a general cultural code with the keyword of participation, sharing, and openness. Web 2.0, in which consumption is being transformed by the participatory web culture, has evolved. However, associated with the evolution of Web 2.0, several significant concerns appears in a society. Among them, this study will focuses on the cyber-ethics issues. There are limitations to solve the cyber-ethics problems only in the technical and legal approaches. Therefore, the current article intends to consider comprehensively the antecedents of cyber-ethics such as individual characteristics, social influence, and cultural characteristics. Specifically, (1) Do individual characteristics(i.e., self-efficacy, locus of control) affect cyber-ethics in the Web 2.0 environment?, (2) Do social influence(i.e., subjective norm) have an effect on cyber-ethics?, (3) Do cyber -ethics have an impact on user participation in the Web 2.0 services(i.e., retrieval and creation)?, finally (4) Do international cultural difference have a moderation effect on the relationship between cyber-ethics and user participation? For testing empirically the hypothesized research model, this study collected questionnaires in South Korea as well as U.S.A. The results showed that individual characteristics and social influence affect cyber-ethics toward user's creative activities in Web 2.0 sites.

기존의 웹 서비스가 수동적이고, 단방향 통신을 축으로 뒀다면 현재의 웹 서비스는 점차 능동적이고 변화되었으며, 양방향 통신 환경을 지향하게 되었다. 이러한 웹 서비스 변화의 흐름을 일컬어 웹 2.0이라 한다. 웹 2.0 세대를 살아가는 사용자들은 기존과 다른 다양한 정보의 홍수에 노출되게 되었다. 이들은 일방적이고, 제한적인 정보를 얻는 기존 환경에서 탈피, 스스로 가치 있는 정보를 생산해 내기 시작했고, 이렇게 생산된 정보는 인터넷을 통해 다른 사용자와 교류하며 더욱 가치 있는 정보를 창출해 나가고 있다. 이런 발전 과정에서 지속적으로 더욱 더 커져가는 정보를 더 빠르고 정확하게 공유하는 기술이 필요하게 되었고, 현재 이런 필요성을 충족시키는데 유용한 기술의 한 갈래로 나온 것이 태그와 시맨틱 웹으로 대표되는 온톨로지 이다. 태그는 정보의 주제나 표제를 나타내는 단어를 해당 컨텐츠 정보를 제공하는 사이트에서 정보 분류 단위로 사용, 이를 통한 더 빠른 정보 공유를 할 수 있게 되었다. 시맨틱 웹은 현재의 인터넷과 같은 다양한 리소스에 대한 정보와 자원 사이의 관계-의미 정보를 기계(컴퓨터)가 처리할 수 있는 온톨로지 형태로 표현하고, 이를 자동화된 기계(컴퓨터)가 처리하도록 하는 기술이다. 이 논문에서는 웹 2.0의 대표기술이라 할 수 있는 온톨로지 기법을 이용, 기존 태그의 정보 분류 효율을 높이기 위한 태그와 태그의 의미관계 형성을 제안하였다.

This paper explores effectiveness of integrating Problem-Based Learning with Web 2.0 technologies in Computer subject matter education for improving quality of lessons and adapting of social needs for pre-service teachers. Students have studied about computer subject matter for 4 times. The process of leaning have recorded by Web 2.0 tools that is one of the cloud services. Also the students have written reflection journals about experiences of PBL process and results. The PBL process and reflection journals have been analyzed by qualitative data analysis. Conclusions are drawn as to potential for the use of Web 2.0 tools for PBL in computer subject matter. The results of the analyses showed the following: 1) Increasing the understanding of the computer subject matter education, 2) enhancing students' competence in using ICT potentially, 3) cultivating teaching and learning strategies on Web 2.0 environment and 4) enhancing competence of future teaching activities through experiencing e-portfolio as a performance-assessment tool.
