Objectives: This study was conducted to develop a participatory learning process and apply it to community empowerment for health promotion. Methods: The participatory learning sessions were composed of three stages according to the modified Freirean model of empowerment education. Stage 1 of generating themes (listening stage) was replaced with a community health forum. Stage 2 of problem-posing was executed via a two-session small group brainstorming discussion for selecting priority community health problems and strategies to solve them. Stage 3 of act-reflect-act, the implementation of the chosen strategies, is ongoing. We tested the feasibility of the participatory learning processes in the pilot programs for health education. Then, 14 Myeon (or Dong) Health Committee members used them in Health Plus Happiness Plus projects for community empowerment to achieve health equity in Gyeongsangnam-Do, Korea. Results: In the pilot program for feasibility, more than 80% of the 95 participants gave positive responses to evaluation questionnaires after three or four participatory learning sessions. Health Committee members successfully selected various strategies relevant to their communities with facilitation, but without any teaching from outside professionals. Conclusions: We successfully applied the participatory learning process to health promotion. However, more studies are warranted to evaluate its long-term applicability.

Path generation methods are required for safe and efficient driving in unmanned autonomous vehicles. There are two kinds of paths: global and local. A global path consists of all the way points including the source and the destination. A local path is the trajectory that a vehicle needs to follow from a way point to the next in the global path. In this paper, we propose a novel method for local path generation through machine learning, with an effective curve function used for initializing the trajectory. First, reinforcement learning is applied to a set of candidate paths to produce the best trajectory with maximal reward. Then the optimal steering angle with respect to the trajectory is determined by training an artificial neural network. Our method outperformed existing approaches and successfully found quality paths in various experimental settings, including the cases with obstacles.

This case study reports on the redevelopment of a course, Local Culture Information Theory offered by the Department of Library and Information Science at C University, into a capstone design course using a project-based learning approach. In collaboration with a local community youth organization, the redesigned course provided an opportunity for LIS students to develop and implement a digital literacy program that enabled high school students to use a variety of digital multimedia technologies to complete a project of digital Human Library featuring video, audio, and digital are such as webtoons. Through semi-structured interviews with 5 students and 3 staff from partner organizations, this study reports on course development process, the establishment of local partnerships, project outcome, as well as suggestions for improvements. In addition, a qualitative analysis of the participating students' interview responses using the Framework for 21st Century Learning (P21) found they developed and improved 11 skills across three core areas: life and career skills including self-direction, project management, collaboration with diverse teams, flexibility, responsibility, leadership; learning and innovation skills including communication and collaboration, problem-solving, creativity, and critical thinking; and information, media, and technology skills through media creation. Lessons learned and recommendations from this case study may be useful for other LIS programs and faculty interested in implementing project-based learning or developing capstone design courses.

Generally, Web Based Instruction has been deployed through whole studies, but the characteristic that is suit various WBI materials to a course of study is a important problem of instructional practice and it also has not to overlook. Therefore, Today's problem that is application of learning materials about the regional autonomy for Web Based Instruction, A plan that it can be solved in the social studies is propelling in this paper. Each of the whole country's region, the learning about the regional autonomy with centering around text, it is a text book, 'Social Investigation', that is developed specially is teaching until now, but developmental model of learning materials about the regional autonomy for Web Based Instruction is proposed by the efforts for improve this problem. Various learning materials about the regional autonomy for Web Based Instruction applied to learn our regional cultural life through the school homepage with based on this proposal. As a result of this study, By sloughing off old sensibility with centering around text, Student's Ability of self directed learning and solving problem is expanded with the dynamic multimedia regional Webpage's environment

Self Organizing Maps(SOM) by Kohonen is very fast algorithm in neural networks. But it doesn't show sure rules of training results. In this paper, we introduce to Bayesian Learning for Self Organizing Maps(BLSOM) which combines self organizing maps with Bayesian learning. So it supports explanatory power of models and improves prediction. BLSOM has global optima anywhere but SOM has not. This is proved by experiment in this paper.

주어진 환경에 대한 특별한 사전 지식 없이 그 환경에 적응할 수 있는 자율이동로봇을 설계할 때는 우선 특정한 상황에서만 유효한 가정들을 될 수 있는 대로 배제하여야 한다. 본 논문에서는 이러한 적응 능력을 갖춘 자율이동로봇을 설계하기 위한 일환으로 유전자 프로그램을 이용하여 로봇의 제어기를 표현하고, 이를 진화하여 로봇이 현재 자신의 주변에서 얻을 수 있는 정보에만 기초하여 목표물을 찾아가는 행동 규칙을 학습하도록 하였다. 로봇은 현재 자신이 놓여있는 환경에 대한 지도를 작성하지 않은 채 현재 자신의 주변에서 얻을 수 있는 지역적인 정보만으로 특정 목표물을 찾아가도록 학습된다. 로봇은 먼저 단층 퍼셉트론을 사용하여 주어진 공간내의 장애물과 목표물을 인지하도록 학습된다. 그 이후 학습된 퍼셉트론을 유전자 프로그램의 함수 노드로 사용하여 트리를 진화시켰다. Khepera 시뮬레이터를 이용한 실험 결과, 로봇은 제한된 지역 정보만을 사용하여 목표물을 찾아가는 행동 규칙을 매우 안정적으로 학습할 수 있었다.

This is conducted with the aim of critical discussions on existing arguments, focusing on the establishment of a higher lifelong learning ecosystem. First, this study discusses the characteristics of university education in Korea and the discourse on the crisis of local universities. Second, the arguments on the establishment of lifelong learning society and a lifelong learning system. Third, the arguments for the establishment of a higher lifelong learning ecosystem are reviewed and practical measures for this are critically discussed. The conclusion is as follows. Measures for the establishment of a higher lifelong learning ecosystem have been discussed in considerable detail, and through this, the possibility of overcoming the crisis of local universities and balanced regional development is sufficient. However, first, the university should play a central role, but this study questions whether university reform could be achieved to suit it. Second, in order to overcome the crisis, national responsibility, responsibility, and continuous support are required. On the other hand, it raised questions about whether cooperation from the current Korean government authorities is possible. Third, local communities should also achieve governance and participate in democratic ways, raising questions about whether a foundation-forming strategy for stakeholder consensus is established.

This paper examined the strategy of experiential learning on Web-based cyberspace for constructive education of social studies. The results as follows : The first, constructivism has brought the paradigm shift in traditional principles of teaching and learning, constructivism is not a theory about teaching, it is a theory about knowledge and learning, learning is understood as a self-regulated process of resolving inner cognitive conflicts that often become apparent through experience, collaborative discourse, and reflection. It is proper for constructive education of social studies to carry out from cognitive constructivism to socio-cultural constructivism, from socio-cultural constructivism to cognitive constructivism and co-constructivism, considering the aim or objectives of social studies education. The second, Web-based Instruction(WBI) can provide learners for constructive environments which can be proper for teaching and learning. WBI was suggested as the best medium for constructive education of social studies in the information age. WBI must design teaching and learning so that may not be teacher-centered, if teacher-centered, it is not constructivism. The third, Web-based cyberspace is the proper mediated experience fields for experiential learning to effectively study regions or space because of overcoming distance fractions through the time-space convergence, it actualize the constructive education of social studies in the space age.
