The variation in the course keeping ability in relation to rudder type is investigated using simulations with 3 different types of rudders (a normal rudder, normal rudder with a plate, and Schilling rudder) under wave conditions. The simulation is developed based on an MMG model with Kijima's regression model, along with the data from Son's experiments and Kose's experiments. A 3-D source distribution method is applied to calculate the source of the external wave forces for the simulation. The coefficients of an autopilot controller that may affect the course keeping ability are also estimated from the simulations with the different rudders. The course keeping ability is evaluated by comparing the forward distances while the ships are simulated with the rudders and autopilot controller.

In many existing studies, the analyses on the application and effect of the project-based learning model (PBL), a student-centered teaching and learning strategy, have been emphasized and carried out in various majors and courses. This case study analyzes the effects of applying a project-based learning model to the engineering accounting course for engineering students in 2021 in the context of the COVID-19 pandemic, compared with the offline course in 2019 and the simple online course in 2020. Project team consisting of 2-3 students carried out online collaborative learning activities for solving open-ended problems through the 5-step PBL procedure including presenting the final result. Except for this online PBL application in 2021, textbooks, lecture contents, assignments, and tests were implemented the same for each semester for three years. Through lecture evaluation and survey by students, the online PBL application semester showed higher effects in inducing student-centered learning, lecture satisfaction, and student competency improvement compared to the non-applying semesters, further, it was evaluated that the online PBL application to the course and evaluation method were more appropriate than other semesters. It is expected that the online PBL method and operation procedure applied in this study can be utilized as a best practice for the design and operation of various online courses for student-centered collaborative learning activities and educational effects.

Universities in Korea have driven universities' new attempts to adopt more learner-centered and active learning in English. Problem-based Learning (PBL) is one of the well-known constructive teaching and learning methodologies in higher education. Our research goal was to design and develop the optimal PBL practices for a college physics course taught in English to promote learning and course satisfaction. For four semesters, we have tried and adjusted PBL components, and looked at the trend of the exam scores and group work achievement in each semester. We found that the number of problems and the duration of problem solving are the critical factors that influence the effect of PBL in a college physics course taught in English by going through iterative implementation. The iterative process of applying, designing, and constructing PBL to physics classes was meaningful not only in that we have found the optimal PBL model for learning a college physics course, but also in that we have been reflecting on the continuous interaction with learners during the course.

강의별학술정보페이지는 하나의 게이트웨이에서 강의정보와 도서관자원을 통합하여 제공하는 서비스로 대학도서관의 정보서비스를 더욱 강화시킬 수 있다. 이는 여러 검색게이트를 갖는 기존의 도서관 자료 제공방식과 달리 강의별 맞춤 정보를 제공할 뿐만 아니라, 강의관리시스템과 연계하여 강의와 도서관자원을 더욱 밀접하게 연계시킬 수 있다. 국외 대학도서관의 경우 강의별학술정보페이지를 대학의 특성에 맞게 다양한 내용으로 구축하며, 대학에 개설된 전체 강의에 대한 페이지를 구축하기 위해 수작업이 아닌 자동화처리 프로그램을 도입하거나 개발하고 있다. 따라서 강의별학술정보페이지 구축 프로그램도 자체 개발혹은 상업 벤더시스템 등으로 다양하다. 하지만, 국내에서는 강의별학술정보페이지 개발이 활성화되고 있지 않으며, 시스템 개발에 대한 구축방안도 모색되지 않고 있다. 이에 본고에서는 문헌연구와 사례조사 방법을 이용해 국내 대학도서관의 적극적인 서비스 방안의 하나인 강의별학술정보페이지 구축 방안을 제안한다. 본 연구에서 제안한 강의별학술정보페이지 구축 방안을 통해 도서관의 적극적 서비스를 마련할 수 있을 것이다.

학습코스 선정에 많은 어려움과 시행착오를 겪고 있는 사용자들에게 수준별 학습코스를 제공하기 위해, ITS(Intelligence Tutoring System)를 위한 동적인 학습자 맞춤형 학습코스 추천 모델을 개발하였다. 이를 위해, 개인화 학습코스 추천모델에서는 먼저 학습자 프로파일을 분석하고, 단어별 가중치를 계산하여 핵심 키워드를 추출한다. 추출된 단어는 Cosine Similarity 기법을 통해 유사도를 측정하고, 최종적으로 유사도가 높은 상위 3개 과정이 학습자에게 추천된다. 추천모델의 효과를 분석하기 위해, 경기도 소재 교육기관에 추천모델을 적용하였고, 만족도 조사를 통하여 설문 항목별 평균, 표준편차, 왜도, 첨도 값을 계산하였다. 실험결과, 정확성, 새로움, 자기참조, 유용성에서 높은 만족도를 보였으며, 추천모델의 실효성을 검증했다. 본 연구는 그동안 국내 외에서 충분히 다뤄지지 않았던 기계학습 중심의 맞춤형 학습코스를 추천했다는 점에서 의미가 있다.

This paper develops a computer model of a cabover type large truck for estimating the effects of the mounted method of frame on handling performance. The computer model considers two mounted methods of frame; flange mounted and web mounted. Frame is modeled by finite elements using MSC/NASTRAN in order to consider the flexibility of frame. The reliability of the developed computer model is verified by comparing the actual vehicle test results with the simulation results. The actual vehicle test is performed in a double lane change course, and lateral acceleration, yaw rate, and roll angle are measured. To estimate the effects of the mounted method of frame on handling performance, simulations are performed with the flange mounted and web mounted frame. Simulation results show that the web mounted frame＇s variations of roll angle, lateral acceleration, and yaw rate are larger than the flange mounted frame＇s variations, especially in the high test velocity and the second part of the double lane course. Also, simulation results show that the web mounted frame＇s tendencies of roll angle, lateral acceleration, and yaw rate advance the flange mounted frame＇s tendencies, especially in the high test velocity and the second part of the double lane course.

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.
