Students' perception on a science program for gifted was investigated. The whole program was designed in consistency and integrity based on the Autonomous Learner Model suggested by Betts & Kercher(1999). 7th, 8th and 9th grade students were enrolled in this program, offered by G Education Institute for Gifted(GEI) located in Seoul. A survey was done to ask students' perception regarding the effect of the program. The survey consisted of statements about the expected effects of the program and students were asked if they agreed with the statements. Most students strongly agreed that GEI's program has positive effects. Students replied that they learned useful and interesting science contents, enjoyed meaningful experience of cooperating with members in small groups, and were challenged by the inquiry tasks. They recognized that they were being trained to become autonomous learners. They also said that their choices and decisions were respected, which resulted in positive effects on their ability to negotiate or to inquire actively. These implies that Autonomous Learner Model had been successfully applied. Although it was not clear autonomy of students was fully grown, the possibility of becoming an autonomous learner was evident. Satisfaction level is higher for the older students, implying that the integrity in the program gave accumulating effect. Students response showed that three sub-programs of GEI, the classes of each subject, conference at the end of the year and autonomous learner training played equally important role for students to learn the process of scientific inquiry and autonomous learning. This was a positive sign that the strategies for scientific inquiry and autonomous learning were embedded and integrated deeply in the program. The results of current research suggests that the integrity of a program based on a specific education model for the gifted could provide better education environment for the gifted students.

The importance of citizen as a key of community safety has increased, and the legislation to support the citizen's activities is continued. However systematic and detailed action plans are not enough to something. Thus, the purpose of this research is to develop the educational program model for the citizens on patrol for the improvement of practical use. The methods of this research are to make and suggest the educational program for citizens on patrol by literature review and cases analysis of educational program implemented one years ago. The findings are suggested as belows. First, the learners need the contents can be practically used in the field and sufficient time of education. Second, the subgoal to achieve the ultimate goal of education program model should be established as 'customer-centered, field-oriented, competence reinforcement', and driving strategy must be composed of four stages as plan-design-implementation-evaluation. Also, for strategy of each stage, detailed sub-strategies from preparation to execution of education have to be considered. Third, education program must be categorized by basic-intermediate-expert courses depending on the level of learners, and theoretically and practically oriented curriculum subjects are organized in balance by each course.

정보화 역기능 현상에 대한 근본적인 대처 방안은 사용자의 정보 윤리적 관점에서 다각적으로 침해 사고에 대해 예측하고 평가하여 정보화 사회가 인간 중심의 바람직한 사회가 될 수 있도록 건전한 윤리 의식을 확립하는 것이다. 하지만, 현재의 정보통신윤리교육은 교육 목표와 내용에 있어서 균형성을 상실하여, 역기능 측면에만 치우치고, 학습자인 학생에게 자율적으로 선택하여 행동할 수 있는 능력을 키워주기보다는 일방적으로 설정된 내용을 전수하는 학습 형태를 벗어나지 못하고 있다. 따라서, 본 논문에서는 정보통신윤리교육에 대한 자기주도적 학습 방법을 웹 기반에서 적용될 수 있는 학습 콘텐츠 모형을 구현한다. 이를 위해 웹 콘텐츠를 이용하여 학습자 스스로가 개별 학습을 수행할 수 있고, 학습내용에 대한 보충 심화 반복 등의 자기주도적인 학습이 가능하도록 설계하였다.

Recently, as more web-based applications are widely used, various methods for education are developed in practical areas. As a result, in many organizations, virtual educations such as WBI learning. CAI, and distance learning are offered actively. With the advantages of web-based education, in order to achieve feasible and efficient effects on education. a new web-based instruction model that considers the abilities, the interests, and the aptitudes of students individually is required. In this paper, a new web-based instruction model, called a hybrid model, is proposed and implemented. And then, two model - the stepwise model and the hybrid model- are applied to a computer accounting class of a vocational high school. Students attend the web-based class in a computer center for 100 minutes autonomously. After the classes, a questionnaire is made in order to analyze both the effect on that class and the learning fulfillment of the proposed instruction model.

Option issuers generally utilize Dynamic Delta Hedging(DDH) technique to avoid the risk resulting from continuously changing option value. DDH duplicates payoff of option position by adjusting hedge position according to the delta value from Black-Scholes(BS) model in order to maintain risk neutral state. DDH, however, is not able to guarantee optimal hedging performance because of the weaknesses caused by impractical assumptions inherent in BS model. Therefore, this study presents a methodology for dynamic option hedge using artificial neural network(ANN) to enhance hedging performance and show the superiority of the proposed method using various computational experiments.
