Today, many universities are confronted with the changing education paradigm such as e-Learning, Distance Education, Virtual University. This IT-based learning paradigm shift is certainly a new opportunity or a threat to our universities. The Local University Community e-Learning Centers that support the demand of e-Learning for their community are recommended. Tn order to operate these centers efficiently, the strategic roles of the e-Learning center should first be defined. To define the strategic roles, We classified the strategic roles of the e-Learning center into four dimensions, (1) to improve management efficiency, (2) to enhance educational service, (3) to acquire competitive advantages, (4) to build new education infrastructure, and each dimension has S or 6 measurement items. As result, to enhance the educational service was considered as the most significant factor among the four dimensions of strategic roles, and the infrastructure building was the next. Through the strategic roles definition and analysis of expected role ratings, we could have recommended the direction and operation policies of the e-Learning centers.

In this paper, we propose a new type of decentralized learning automata for the control finite state Markov chains with unknown transition probabilities and rewards. In our scheme a .betha.-type learning automaton is associated with each state in which two or more actions(desisions) are available. In this decentralized learning automata system, each learning automaton operates, requiring only local information, to improve its performance under local environment. From simulation results, it is shown that the decentralized learning automata will converge to the optimal policy that produces the most highly total expected reward with discounting in all initiall states.

Ecosystems of the southwestern tidal flats in Korean peninsula have been seriously injured by human activities. The results are mainly due to the lack of public recognition and education on tidal flats. In particular, thoughtless visitors in tidal flats are giving rise up damages because of non-systematic experience programs to tidal flat ecosystems. Therefore, experience programs friendly to natural tidal flats are necessary as a plan to reserve tidal flats and to enhance the effects of environment education on the flats. Experience learning programs on tidal flats can divide into direct experience, indirect experience and local society works. Direct experience work must undergo tidal flats directly and consider on forming the flats with natural refinement functions. Indirect experience includes deeper knowledge on role, circumstance and ecosystems of the flats on the bases of direct experience on the flats. In addition, local society learning must have the feeling and understanding on socio-cultural characteristics of local society itself through above two works. Experience activity would be a kind of injuring one to tidal flats. However, appropriately planned experience and education works on tidal flats could be sustainable development to attract desirable human activity on coastal ecosystems.

With the evolving complexity of connected vehicle features, the volume and diversity of data generated during driving continue to escalate. Enabling data sharing among interconnected vehicles holds promise for improving users' driving experiences and alleviating traffic congestion. Yet, the unintentional disclosure of users' private information through data sharing poses a risk, potentially compromising the interests of vehicle users and, in certain cases, endangering driving safety. Federated learning (FL) is a newly emerged distributed machine learning paradigm, which is expected to play a prominent role for privacy-preserving learning in autonomous vehicles. While FL holds significant potential to enhance the architecture of the Internet of Vehicles (IoV), the dynamic mobility of vehicles poses a considerable challenge to integrating FL with vehicular networks. In this paper, a novel clustered FL framework is proposed which is efficient for reducing communication and protecting data privacy. By assessing the similarity among feature vectors, vehicles are categorized into distinct clusters. An optimal vehicle is elected as the cluster head, which enhances the efficiency of personalized data processing and model training while reducing communication overhead. Simultaneously, the Local Differential Privacy (LDP) mechanism is incorporated during local training to safeguard vehicle privacy. The simulation results obtained from the 20newsgroups dataset and the MNIST dataset validate the effectiveness of the proposed scheme, indicating that the proposed scheme can ensure data privacy effectively while reducing communication overhead.

This study develops and applies a service learning course that integrates university curriculum with the local community in housing and interior design. The results of the study are as follows. First, the service learning course of the housing and interior design was developed as a six-week lecture based on the project model with the theme of housing for the socially disadvantaged. Second, this course was implemented with faculty, students, interior designers, and service recipients to engage in activities to improve the educational environment of local child centers. Next, students engaged in the service learning course and continuously conducted reflection activities to enhance the effectiveness of learning. In reflection activities, students assessed that self-directed capabilities increased as has employing the coordination and applicability to meet identified community needs. Finally, faculty, students, and experts (including institutional experts and supervising departments) evaluated course practice and educational outcomes. Experts assessed that the course clarified course objectives, utilized various learning strategies, and showed that the structural reflection mode of learners and professors was overwhelmingly positive. The results indicated that service-learning courses enable students to integrate academic study with social work to better understand course content through direct engagements in experience learning. Furthermore, students are empowered by participation in public services that benefit service clients and consultants as students take more personal responsibility for learning.

본논문에서는 라마르크 진화와 볼드윈 효과를 진화전략에 적용하여 진화전략의 수렴성에 대해서 고찰한다. 또한 진화전략의 탐색법으로 랜덤 지역탐색법과 강화 지역 탐색법을 제안한다. 랜덤지역탐색은 미리 정한 일정한 회수의 지역탐색을 랜덤하게 수행하는 것이고 강화 지역탐색은 주어진 범위내에 존재하는 모든개체의 적합도를 평가하여 가장 적합도가 높은 개체 주변을 탐색하는 것이다. 이러한 관점에서 라마르크 진화와 볼드윈 효과를 기본으로 하는 강화 지역탐색은 단순히 랜덤하게 주변개체의 적합도를 탐색하는 것이 아니라 해 공간상에서 적합도가 높아지는 방향으로 지역 탐색을 행함으로써 랜덤 지역탐색에 비해 보다 효과적으로 주변 개체를 탐색할 수 있어 전역적 탐색능력의 향상은 물론 수렴속도의 향상은 가져 올수 있었다. 결과적으로 진화과정에 학습을 도입함으로써 진화만으로 최적해를 탐색할때보다 그성능이 향상됨을 볼 수 있다, 제안한 방법은 다양한 함수최적화 문제에 적용하여 그 시뮬레이션을 통해 학습이 진화에 미치는 영향에 대해서 고찰한다.

This study is undertaken to present the facilitation plan of English library that specialized the resource-based learning to provide learning that is suited for student's own learning style and self-leading learning as the method to learn contents required for individuals as a method for improving the English education environment in the rural areas. For this purpose, a study was conducted to find out the possibility of facilitating English library in the rural areas on the basis of consulting for structuring and operating English library in public libraries located in isolated areas clustered with low income class in the urban areas where the conditions are similar to the rural areas and results are shown as the followings. First, it displayed the possibility to have the rural area located with many closed schools or small-sized schools to facilitate the available facilities to build up the environment to specialize in English education that would be as comparable as any facilities in any urban setting. Second, it would enable the conditions to moderate the conflict on education environment for local residents who felt inequality in education by providing the benefit for fine education linked to public education through English library without going through private education. And third, English library that has the limitations in locality or economic means would actively participate by local educational institutions and volunteers to enhance the sense of master for the local residents and bring residents together to make positive impact on local economy facilitation.
