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.
서버리스 컴퓨팅을 위한 다양한 컨테이너 런타임 환경에서 라이브러리 공유 성능 분석

서버리스 컴퓨팅에는 가상머신보다 가벼운 장점을 지닌 컨테이너 기술이 많이 사용되었다. 하지만 여러 사용자들의 어플리케이션이 하나의 서버 인스턴스를 공유해서 사용하기 때문에, 취약점으로 인해서 여러 문제점이 생길 수 있다. 이에 서버리스 컴퓨팅 제공자들은 서버리스 컴퓨팅에 적합하며 보안을 강조한 기술들을 발표하고 있다. 대표적으로 구글에서 개발한 샌드박스 형태의 컨테이너 런타임을 제공하는 gVisor 와 오픈스택 재단에서 개발한 Kata Containers가 있다. 본 논문에서는 미리 준비된 라이브러리를 공유하여 서버리스 컴퓨팅의 콜드 스타트를 완화시키는 관점에서, gVisor와 Kata Containers 환경에서 라이브러리를 불러올 때 기존의 도커 컨테이너 환경과의 차이를 비교하고 분석한다.

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.
