Recently, as the increase of internet users and the needs of the new educational paradigm, many educational institutions go into the cyberspace system. Especially, it is increase that the cooperative extension for supplying the degree and the remote lectures in the university itself. Mostly those lectures have the form of discussion with theoretical course in the center. It is needed to the development of educational tools for the other courses. The cyber education systems are due to be developed more and more. So we should consider the effective usage of recent techniques like this. Accordingly, I'd like to say what is the method of using effectively the cyber communication. It would be considered about the part of cyber communications and the educational effects that has classified into three parts: the cyber communication as a educational medium, the communication for the cooperative studies, and the theological background of the cyberspace communication. Moreover it is proposed the two parts of the effective study directions; the constitution of the community study, and the effective study factors.

This paper is experimental study to inspect effects of problem solving ability and programming interest using Pico Cricket of the educational robot. The programming learning which is regarded as the very core of information subject improves problem solving ability. But the programming teaming does not display the effects properly, because the programming learning studies a grammar manual. The educational robot has the advantage to approach the programming learning easily for containing entertainment. The Pico Cricket of the educational robot has the advantage not to induce competition but to compose a cooperative learning environment. Also, the Pico Cricket is able to be had interest of programming learning to girl students, because the Pico Cricket is able to suggest life-centered and cooperative contents which girl students like. Accordingly, This paper is study which the programming learning using Pico Cricket affects the problem solving ability and programming interest and men and women's comparison study.

In information society, enhancing information literacy is a common goal of the academic and school libraries. Consequently the academic libraries connect with the school libraries through information literacy In this study, a academic library visiting program is presented and proposed as a policy to link the academic and school libraries. This program may be a alternative to activate school library-based teaming and overcome lacks of resources and teacher librarians, in the academic libraries. it may be a policy to improve lacks of materials and carrels and overcome the problem of service increase in the opening academic library for local communities. And it will contributes to the educational role or the librarian.

This study examined the analyses of students and teachers' perceptions on learning style in IBL. This study analyzed 386 elementary school (ES) and 627 middle school (MS) students and 130 cyber teachers how they perceived learning styles in IBL. They filled out the 15 items questionnaire about three different learning styles (self-directed preference style, cooperative preference style, and dependent style) in IBL, and were compared their perceptions in terms of students comparisons (ES vs. MS) and students and teachers comparisons. The results showed that the students and teachers preferred the self-directed preference learning style rather than cooperative preference style and dependent styles. However, the teachers judged the students more likely self-directed and dependent style than the students judged themselves. Also, there were statistically significant differences between ES and MS students on the dependent learning style and ES and MS teachers as well. In conclusion, this study suggests the different design and development strategies in IBL contents for ES and MS students preferred teaming styles. Tutoring strategies for cyber teachers should be also developed to understand learners' different loaming styles in IBL.

This paper presents a reinforcement learning framework for stock trading systems. Trading system parameters are optimized by Q-learning algorithm and neural networks are adopted for value approximation. In this framework, cooperative multiple agents are used to efficiently integrate global trend prediction and local trading strategy for obtaining better trading performance. Agents Communicate With Others Sharing training episodes and learned policies, while keeping the overall scheme of conventional Q-learning. Experimental results on KOSPI 200 show that a trading system based on the proposed framework outperforms the market average and makes appreciable profits. Furthermore, in view of risk management, the system is superior to a system trained by supervised learning.

This study aims at grasping the influence of antecedents within SCM to information sharing and cooperation as well as the influence of information sharing on cooperation among the small & medium-sized manufacturing industries, thus ultimately opening the way to the study on the influence of major activities such as information sharing and cooperation within SCM on the business performance by classifying such influence into low perspectives of BSC. The results of this study revealed that the antecedents such as commitment and cultural similarities exercised a significant influence on information sharing while mutual trust and the size of a corporate weighing with cooperative activities. It also identified the fact that information sharing bore a significant influence on cooperation in terms of relationships among activities. For the relationships between the SCM activities and performance, cooperation proved significant to all four balanced scorecard performances with little significant influence of information sharing on balanced scorecard performance. However, taking into consideration of the significance of information sharing on cooperation as well as the significant influence of cooperation on balanced scorecard performance, it fumed out that information sharing also effected a indirect influence on such four types of balanced scorecard performance. In this regard, based on the results of this study, it was identified that information sharing and cooperation, major activities within SCM, had either direct or indirect influence, through the influence of antecedents, on the business balanced scoreboard performance measured from a customer perspective, a business process perspective, an innovation and teaming perspective and a financial perspective.
