  • The Government has established the infrastructure for knowledge and information-oriented society, strengthening the ICT technology education. Although information knowledge ability of learners is prerequisite to educate ICT, but systematic educating courses and time for that are insufficient, and many difficulties have been pointed out. In order to solve such problems, this study developed Web-based computerized adaptive testing system using the item response theory. This system enables the learners to evaluate their own ICT knowledge abilities in their school or home by using familiar web interface and to perform supplementary or deepening study according to the results, and consequently, smooth education of ICT application will be achieved. In addition, this system will be a very effective method for the elementary/middle/high-school ICT knowledge ability certification system.

  • The purpose of this study are as follows : First, This study conceptually provide an insight of reasons that organizations seek to create, acquire, store and distribute knowledge at the level of an organization and of process how they can transform or evolve to knowledge based organizations. Second, this study confirms examine what theories can be used to knowledge management, how such theories can be useful to analyse knowledge management and provide a theoretical foundation for knowledge management research. Applied to the theories of knowledge based and resource based view and institutional theory, the essence of knowledge management confirms that the organization finds job-related knowledge and know-how retained by individual of organizational members systematically and shares common knowledge within the organization and explains knowledge creation, multi-dimensional knowledge transition and share in all dimension of individual, group, and organization. As a result of comparative analysis of theory of organizational knowledge creation theory, In knowledge management, building of knowledge-creative culture, transitional process of explicit knowledge and tacit knowledge, knowledge creation and knowledge operation are important. In the basis on these study results, we discussed how the organizational knowledge creation theory can be used to manage knowledge in the organization, and also proposed hypotheses based on some arguments against the universal acceptance of the theory.

  • This study attempted to apply flip-learning and to evaluate college students' awareness and academic achievements. Twenty-seven students in single-group dental hygiene were applied to the dental radiology class for four weeks. Data collection was done after the flipped-learning and collected data were analyzed using frequency, average and content analysis using SPSS 18.0. As a result, awareness of overall class was a positive response, and academic achievement evaluation was not statistically significant. It was found to be an effective educational program. However, the academic achievement evaluation was not statistically significant and it was considered that the evaluation system needs to be different according to the learning method.

  • This paper reports the empirical results of comparing the willingness to pay(WTP) for health risk reductions and the willingness to accept(WTA) for risk increases using experimental market methods in the first time in Korea. Health risks were defined as probabilities of premature death from exposure to one of As, Pb, and THM in tap water. A total of six experimental markets with 15 participants in each experiments were held using 20 repetitive Vickrey second-price sealed-bid auctions. To compare the effects of market experiences, trading a marketed good, candy bar, was introduced before the trading the non-marketed good, drinking water risks. Moreover, an objective risk information was provided after the first 10 trials to incorporate learning processes. Regardless of marketed or non-marketed goods, the mean of WTA exceeded the mean of WTP at the first auction trial. As experimental trials proceeded, the disparity between WTA and WTP for marketed goods disappeared. However results for non-marketed goods were rather mixed to the extent that WTA for health risks from As (relatively high risk leves) were significantly larger than WTP, while there were no significant difference between WTA and WTP for health risks fro Pb and THM (relatively low risk levels). On the other hand, participants seemed to respond in a 'rational' manner to the objective risk information provided, with positive learning effects of market-like experience(especially in the WTA experiments).

  • 최근 프로그래밍 교육에서 학생들의 학습 성취도를 빠르고 정확하게 평가하기 위하여 자동 채점 시스템을 사용한다. 강의를 통해 습득한 이론적인 지식을 이해하기 위해 직접 코드를 작성하는 실습이 진행되는 프로그래밍 교육에서 효과적이기 때문이다. 현재 실습에 필요한 실습문항의 대부분은 강사가 직접 생성해야 한다. 특히 강의내용을 바탕으로 예제 소스코드를 이해하여 빈 칸에 알맞은 코드를 작성하는 실습은 강사가 직접 빈 칸에 해당되는 부분을 예제 코드에서 지정해줘야 하는 추가적인 작업이 필요하다. 이러한 빈 칸 채우기 문항은 일반적으로 빈 칸이 고정된 행태이기 예문에 학생들이 답안을 공유하기 쉽다. 이를 막기 위해서 강사는 유사한 내용의 빈 칸 채우기 문항을 추가적으로 생성해야 한다. 하지만 대부분의 자동 채점 시스템은 이를 지원하지 않거나 강사에게 빈 칸을 직접 지정하도록 하는 경우가 대부분이다. 따라서 본 논문에서는 이러한 문제를 해결하는 빈 칸 채우기 문항 자동생성기법을 제안하고 적용 사례를 보인다.

  • Creativity is a fine ability among major values of human resource in knowledge-based society. The purpose of this study is to identify the components of the informatics creativity based on domain-specificity and confluence theory. To explore these components, a three-round, classical Delphi process was administered with an expert panel of 31 individuals. All members of the expert panel initially responded to open-ended questions, and the qualitative results were analyzed. The subsequent two rounds of the Delphi required quantitative responses in which the expert panel was asked to indicate the level of importance using a five point Likert scale associated with specific items. As a result of the Delphi survey, total of 32 items were selected as three core areas such as congnitive, affective and environmental components of informatics creativity.

  • B2B Marketplace상에서의 거래에서 나타나는 주요한 특징은 다품종 및 대량의 물품 거래가 n:n거래 관계에 놓여있다는 점과 거래자가 원활한 거래 및 기업 내 관리를 위해 각자의 전자 카탈로그를 이용한 거래를 원한다는 정이다. 하지만 개별적인 전자 카탈로그 사용과 미흡한 표준안은 전자 카탈로그 상호 연계의 걸림돌이 되어 시장 형성의 걸림돌이 되고 있다. B2B Marketplace는 표준 분류체계를 중심으로 거래 대상 상품을 재분류하여 구매 당사자간의 거래 대상 물품에 대한 상호 애핑을 지원하는 방법 등으로 이를 충족시키려 하고 있다. 하지만 요청되는 다량의 물품에 대해 매번 분류를 수행해야 하는 고비용의 작업이라는 문제점이 있다. 본 논문에서는 이를 극복하기 위하여 기계학습 기법을 이용한 전자 카탈로그 상품 자동분류기를 모델링하고 이를 구현하는 것에 초점을 두었다. 상품의 속성별로 분류에 끼치는 영향력이 다론 것이라는데 착안하여 전자 카탈로그를 상품 단위로 재 모델링 하였으며 속성별 정보가 풍부하지 못한 정물 극복하기 위하여 속성값을 어휘 단위로 구분한 데이터를 추가 하는 확장 모델을 정의하였다. 또한 해당 모델을 학습시키기 위한 알고리즘으로는 속성별로 다른 가중치를 부여 할 수 있도록 확장된 Naive Bayesian Classifier를 고안하였다. 그리고 이론 B2B Market Place상의 실 데이터에 적용하여 고안된 모델의 유효성을 검증하였다.
