IT project is a knowledge-based project with high uncertainty in role assignment and task allocationamong team members. This study empirically investigate steam members' interactive behavior in IT projects based on the framework of social interdependence theory. The goal and task interdependencebetween team members were posited as antecedents of project performance with communication effectiveness and knowledge sharing as mediating variables. To test the research model, a dataset was collected form IT and business professional pairs of 123 IT project teams. The results indicated that the theory of social interdependence is applicable to explaining the promotive interaction in IT project teams. In detail, task interdependence appears to have influence on both promotive interactions (communication effectiveness and knowledge sharing), and goal interdependence influences only on communication effectiveness. Knowledge sharing is found to be a significant mediator between social interdependence and project performance. However, communication effectiveness only indirectly influences project performance via knowledge sharing. Academic and practical implications are discussed.

Production rule based knowledge representation method has many advantages, but has the difficulties in maintaining the consistency of knowledge. Since the consistency maintenance of knowledge exercises a marked effect on the reliability of inference results, the system for consistency maintenance of knowledge is indispensable to increase the reliability. In the most popular pairwise checking method among consistency verification methods, the valuable rules can be omitted and it takes much time in checking the consistency when the rules are numerous. So, this paper is to propose and implement the verification system which can remove the structural errors and semantic ones, making up for the defects of pairwise checking method by using the certain property list and eventual property list and improving the steps of verification.

The purpose of this study was to configure a model geared toward predicting factors affecting the sexual behavior of college students and the path of their influence. The standardized path coefficients of factors that might affect their sexual behavior were calculated, and the total effects of the factors were checked when the path of their influence turned out significant. As for the path of the factors affecting the sexual behavior of college students in a firsthand manner, dating exerted a firsthand influence on sexual knowledge. That had the greatest total effect on sexual knowledge, and those with dating experiences had a better sexual knowledge. Sexual knowledge exercised a firsthand influence on sexual attitude, and that had the largest total effect on sexual attitude, as the students who had a better sexual knowledge took a more positive sexual attitude. Sexual roles affected sexual attitude and sexual behavior in a firsthand way, and sexual roles had the biggest total effect on sexual behavior. Androcentric and open sexual attitudes were permissive, distorted and led to more sexual behavior.

Knowledge management (KM) has been considered to be an effective means of learning from past projects to effect continuous performance improvement in the construction industry. Despite the growing importance of KM in the construction industry, the usage and effectiveness of IT tools for implementing KM are limited to some extent. Case studies of current KM practices in Korean construction sectors revealed that the chief causes of this problem are the top-down approach of the current practices. To address this challenging issue, this research proposes bottom-up approach, which motivates knowledge creation by shifting the ownership of contents, and facilitates effective reuse of knowledge by providing rich contextual information.

This study intended to analyze pre-service elementary teachers' perceptions of teacher knowledge based on the Technological, Pedagogical, and Content Knowledge (TPACK) framework. Seventy-four pre-service elementary teachers who were enrolled at an University of Education located in mid-continent of Korea participated in a survey. Results of the survey was analyzed using Importance-Performance Analysis (IPA) method. It was found that perception of importance was significantly higher than that of performance at all seven domains of the TPACK. IPA matrix extracted from the survey indicates that Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK), and TPACK which are related to technology especially need to develop. Results of this study also show the necessity to support pre-service teachers so that they can have opportunities to develop and use technology-related knowledge and skills. This study especially implies that technological knowledge needs to be integrated with content and pedagogical knowledge when implementing curriculum and educational programs for pre-servie elementary teachers.

현재 지식에 대한 중요성의 인식으로 각 기업별로 정보 시스템 구축을 통한 지식의 축적을 시도하고 있고 데이터 웨어하우징(DW), 데이터마트, 전사적자원관리(ERP) 등 지식관리를 위한 핵심 시스템을 통해 구성원들간에 정보를 교환하고 있다. 이처럼 기업의 지식들이 생성, 공유, 관리, 보관되고 이를 보다 체계적이고 정교하게 구축하여 이용자가 보다 쉽게 사용할 수 있는 정보기술이 지식관리시스템(KMS)이다. XML은 여러 어플리케이션들의 표준화된 정보 전달의 매개가 되는 스펙으로 지식관리의 구조적 체계를 공유할 수 있는 기반을 만들어 줄 것이다. 지식 시스템은 분산된 정보와 시스템들의 상호 연동성을 보장할 수 있는 유연성과 확장성으로 표준규격의 XML을 연구하였다.

지식검색은 방대한 지식정보 데이터를 바탕으로 사용자의 질문에 대한 답변을 검색하는 시스템이다. 이러한 사용자 참여로 구축된 지식정보는 잘못된 답변으로 인한 신뢰성 부족과 중복 답변 등의 문제점이 있어, 원하는 답변을 찾기 위해서는 지식검색에서 다수의 답변을 읽고 그 답변의 진위여부를 판단해야만 한다. 만일 정답에 포함되는 단어나 어구가 답변들에서 나타내는 통계적 특성을 활용하여 사용자가 원하는 답변을 제시할 수 있다면, 지식검색의 효용성과 신뢰성이 크게 향상될 수 있다. 본 논문에서는 지식정보 데이터 분석을 통해 사용자의 질문의 유형을 단어, 목록, 도표, 글의 4가지 유형으로 분류하고, 각 분류에 대한 사용자 질의어의 답변을 요약하는 방식을 제안한다. 단어, 목록, 글 유형은 TF와 IDF, 어휘 간의 거리 정보를 통해서 중요 단어를 추출하여 각 유형에 적합한 형식의 답변을 사용자에게 제시한다. 도표형은 답변들에서 사용자의 의견 정보를 추출하여 의견 통계를 도표로서 제시한다.

비구조 텍스트로부터 지식을 추출하여 온톨로지 기반 지식베이스를 구축하는 연구가 최근 국내외로 다양하게 진행되고 있다. 이러한 목적을 달성하기 위해서는 자연어 텍스트에서 나타난 지식요소들의 다양한 속성들을 표현할 수 있는 온톨로지를 필요로 한다. 디비피디아 역시 위키피디아의 지식들을 표현하기 위하여 디비피디아 온톨로지를 사용한다. 그러나 디비피디아 온톨로지는 위키피디아의 인포박스에 기반한 온톨로지로서, 요약된 정보를 설명하기에는 적합할 수 있으나 자연어 텍스트로 표현된 다양한 지식표현을 충분히 커버하는 것은 보증되지 않는다. 본 논문에서는 자연어 텍스트로 쓰여진 지식을 디비피디아 온톨로지가 충분히 표현할 수 있는지를 검토하고, 또한 그 불완전성을 프레임넷이 어느정도까지 보완할 수 있는지를 살핀다. 이를 통해 한국어 텍스트로부터 지식베이스를 자동구축하는 온톨로지 인스턴스 자동생성 연구의 방향으로서 디비피디아 온톨로지와 프레임넷의 효용성을 전망한다.

The effect of knowledge sharing and its importance have been reported in the information systems literature. However, little has been learned about the impact of knowledgeexchange web sites. This study explores relationships between individual characteristics such as personal innovativeness in the domain of information technology (PIIT), computer selfefficacy (CSE), and computer anxiety (CA), user involvement (UI), and knowledge sharing in a knowledge.exchange website. In order to examine our research model, we adopted a survey research design based on the Structural Equation Modeling method. By analyzing 241 samples collected, we conclude that UI and CA are valuable to discuss in terms of their theoretical and practical implications. This study not only extends the research on personal innovativeness and knowledge sharing, but also suggests a need for focused research efforts to investigate real practices on knowledge sharing. This study initiates this kind of efforts to make a relevant tie between design of knowledge sharing applications and the success case in the commercial field to encourage users to share their knowledge.
