The vehicle-mounted mine detection system with large detection sensor modules can search wide areas with a fast detection speed. To mount the heavy mine detectors on a manned or unmanned vehicle, it is necessary to design the detector driving mechanism and control system based on the considerations driven from the characteristic analysis and the operation requirements of the detection system. Furthermore, while operating the mine detector mounted on a mobile vehicle, it is significant to keep the height from the ground to sensors within a certain distance in order to get a qualified detection performance. As the mine detection sensor, we used ground penetrating radar widely used to geotechnical exploration, mine detection and etc. In this paper, we introduce a driving mechanism through analyzing the characteristics of the vehicle-mounted mine detection system. We also suggest a method to automatically control the distance between the ground and GPR by utilizing the GPR output values, used to detect mines at the same time.

Recently, skid steering methods have been increasingly applied to unmanned ground vehicles since they can provide a narrow turn that general steering methods like ackerman steering may not provide. However, dynamic behaviors of the skid steering vehicles with articulating arms which occur during a steering are very complicated and coupled. This makes it difficult to control vehicles and in severe case vehicles may loose stability. There are two methods to control unmanned ground vehicles. The first one is speed control method generally used with easiness and robustness in remote vehicle control. The next one is torque control allowing the vehicles to get better performance in several cases provided careful application is achieved. This paper addresses dynamic phenomena of skid steering vehicles during steering and compares with vehicle driving control methods between torque(traction force) control and speed control.

The purpose of this study is to find ways to revitalize training by comparing teachers' satisfaction with education training, usability of training content, and perceptions of continuous support and networking after artificial intelligence convergence education training for elementary and middle school teachers. The subjects of this study were 353 elementary school teachers and 304 middle school teachers, a total of 657 people. The main results of the study are: First, elementary and middle school teachers showed high satisfaction with artificial intelligence convergence education training, showing a positive perception of the practical usability of the training content and its application in educational settings. Second, there was a significant difference in satisfaction with educational training between elementary and middle school teachers in the performer level and in the utilization of training contents in the performer and leader level teachers, but there was no significant difference between teachers in continuous support and networking. Through this study, the plan to revitalize artificial intelligence convergence education after training is, first, to develop a customized curriculum for each training stage according to the school level. Second, we need to support teachers so that they can return to school and engage in self-development related to artificial intelligence and big data. Third, support should be provided to promote continuous communication and cooperation with other teachers and to exchange and share information through networking.

The purpose of this study is to investigate the perception and status of distance education of elementary, middle, and high school students in the Chungcheongnam-do Office of Education, competency, and the reality and needs of distance education in preparation for the digital era. For this study, 447 elementary school students, 197 middle school students, 136 high school students, and a total of 870 people participated in the survey. As a result of the main analysis of the study, first, the overall average score of students in the Chungcheongnam-do Office of Education's perception of distance education (3.04 points), reality (3.06 points), competency (3.45 points), and reality and needs (3.31 points) in preparation for the digital transformation era was normal (3.0 points). Second, distance education conducted in elementary, middle, and high schools did not reduce the difference in students' learning ability, and the effect and satisfaction were low, and as a result, the preference for distance education was also low. Third, as for the competency of distance education, the higher the school level, the higher the overall average score in the planning and use of distance education. As an improvement direction for the settlement of distance education for students in the school field, first, teacher training is needed to solve students' difficulties in distance education by reflecting students' distance education status. Second, it is necessary to develop a plan to improve students' ability to increase the learning effect in distance education. Third, parent education is needed to increase the effectiveness of distance education for students at home. As a suggestion, a comparative study for students, parents, and teachers is needed by expanding this study.

심층면담을 통한 지역 협력 방과후학교 유형 도출 연구

강신천 한국방과후학교학회 2022 방과후학교연구 Vol.9 No.2

Various attempts and efforts of after-school schools in connection with the region have been in full swing since 2016. Although there is a way to link regions, there is also human resource linkage such as instructors, but active linkage with the local area is being promoted mainly centered on the design of educational spaces and experiences. It is necessary to identify and categorize the actual situation of regional cooperative after-school schools that are increasing quantitatively, identify the demands for after-school cooperatives with the region, and derive future development directions or plans. To this end, this study conducted in-depth interviews with local community officials who could cooperate. In order to systematically classify and analyze the results of the in-depth interview, an analysis tool was created and analyzed by referring to the CIPP model to analyze detailed elements of input, process, and output. Based on the results of the analysis, the types of regional cooperative after-school schools were largely divided into community-only type, complex type, community-centered school cooperation type, and school-centered community cooperative type.

생성형 AI 기반 교수설계 지원 플랫폼 개발 및 시범 적용

강신천,허희옥 한국컴퓨터교육학회 2023 컴퓨터교육학회 논문지 Vol.26 No.6

The aim of this study is to develop and conduct a pilot-study of the platform that supports instructional design (ID) based on generative artificial intelligence (AI). The ChatGPT as a generative AI released in November, 2022, has driven a new integration of education and AI. The use of digital technologies including AI has become a key issue in the educational field. Meanwhile, the 2022 revised curriculum in Korea places a significant emphasis on digital literacy and AI as educational purposes as well as tools in educational practices. So this study developed a prototype platform of automated ID based on generative AI that supports teachers course preparation and ID. The platform included functions to carry out major activities of a ID process, such as the selection of national achievement standards relevant to the course, the identification of cognitive components of Bloom’s taxonomy and the relevant learning objectives, the design of course structure including introduction, development and summation, and development of learning tasks and test items. In the platform, AI provides and suggests information relevant to each activity. We conducted usability testing about the platform and obtained above 3.5/5.0 points in both basic and design domains. The findings underscored the need for a more intuitive design and a UX-based interface. In conclusion, the study suggested developing the whole process of ID for further study.
