The purpose of this study was to redesign a problem-based learning (PBL) curriculum and compare the differences between the previous and redesigned PBL based on the results of course satisfaction and student assessments. The PBL was redesigned using curriculum design guidelines (including revisions of curriculum objectives, learning components, learning environments, and assessment methods) that were developed based on previous studies and evaluation results. A comparative study was employed using course satisfaction surveys from the previous and redesigned curricula, and a total of 45 students participated. We also compared student assessment results from concept mapping, learning issue reports, modified essay questions, and reflection journals. We identified four key findings. First, we explored the possibility that the redesigned PBL could be implemented by student facilitators without professors as tutors. Second, the redesigned PBL fostered group dynamics that facilitated developing communication skills and collaborative learning through small-group discussions. Third, the new learning elements added in the redesigned PBL made a meaningful contribution to enhancing students' clinical reasoning based on hypothetico-deductive reasoning. Fourth, concept maps in redesigned PBL contained more complex and various nodes and connections, and the levels of the nodes were more appropriate. The implications of this study can provide meaningful preliminary information for redesigning PBL curricula for medical students to develop their essential competencies through PBL.

In this paper, an automatic Simultaneous Localization and Mapping (SLAM) method is studied. This method is based on Grid-based FastSLAM and frontier-based exploration. Firstly, the Grid-based FastSLAM generates an occupied grid map that is intuitive and that easily generates the frontiers that are required for frontier-based exploration. To execute a SLAM, the robot must move to a frontier to explore the unknown area in order update the map. Before the robot selects a frontier as a sub-target, it has to select a frontier for efficient map building. In this research, a method for selecting a frontier among several candidates is suggested by means of the Analytic Hierarchy Process, which is a multi-objective decision making method. In the simulations, several cases are studied to demonstrate the performances of the proposed method and the results are compared with conventional frontier selection method.

이 글은 정합성과 적절성을 중심으로 광역지방자치단체의 고령사회정책을 모니터링하고, 이를 바탕으로 광역지방자치단체의 고령사회정책 내실화 방안을 제시하는 데 목적을 두고 진행하였다. 분석 결과 광역지방자치단체의 고령사회정책 범위는 대부분 노인복지정책에 한정되어 있었다. 비전·목표·추진전략은 중앙의 정책 기조와 유사한 흐름을 유지하고 있으나, 일부 차이를 보였다. 광역지방자치단체의 고령사회정책 내용은 소득보장, 건강, 돌봄, 여가문화에 치중되어 있고, 예산은 매칭사업 중심으로 배정되어 있다. 이러한 연구결과를 바탕으로 광역지방자치단체의 고령사회정책 내실화를 위한 방안으로 고령사회정책의 범위 명확화, 광역지방자치단체의 원활한 정책 수행을 위한 관리체계 마련이 필요함을 제안하였다. The purpose of this article was to monitor the social policies of metropolitan local governments on the elderly, especially in terms of their consistency and appropriateness, and to present measures that could improve these policies. Our analysis found that most of local governments’ social policies on the elderly were limited to welfare assistance. The visions, goals, and implementation strategies of those local policies were mainly in the same direction as those of the central government policies, but some differences were observed. Local government's social policy projects for the elderly are focused on their income security, health, care, and leisure culture. The budget is mainly allocated to matching programs. Based on these findings, this article suggests that in order to improve the substance of these policies, it is necessary to clarify the scope of each and establish a system for managing their implementation.
