This study found that the use of the metaverse enabled two-way communication online, regardless of time and place, making it possible to achieve teaching and learning goals. As applied subject (Occupational ethics in science and engineering) that allow for curriculum activities using the metaverse, team activities, and Problem Based Learning (PBL) selected. This study selected the teaching method that combines team activities of in-class and metaverse depending on the team projects and applies them appropriately according to the class procedure. Basic theoretical content learning and team activities related to the class content were conducted during class time. Also In Gathertown, team projects were carried out through team activities. As a result, this study confirmed that the PBL-subjects curriculum are definitely possible through the progress of the metaverse activities. If the educational environment for metaverse activities and the instructor's preparation and participation are supported, a very high learning effect is expected.

Purpose: The purpose of this study was to develop online aging and health management education for undergraduate students and to evaluate its effects analyzing the differences in knowledge and attitude toward aging and the elderly. Method: An Online aging and health management education program was established through analysis, planning, content framing and production, program application, and evaluation stages. The study sample consisted of 98 undergraduate students in one university in D city. The instruments used were FAQ I for knowledge of aging and a 20 item semantic differential scale for attitude toward aging and the elderly Results: The results of this study were as follows. First, undergraduate students' knowledge level was low and attitudes were negative at the baseline. Second, after the class, knowledge scores improved significantly from 14.44 to 20.12. In addition, the attitudes toward elderly and aging changed from negative to a more positive way showing a 23.57 point difference. Conclusion: This study shows that the online aging and health management education program was an effective educational method to improve knowledge and attitude of aging for the young generation such as college students.

This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.

This study aims to investigate effects of scaffolding on writing apprehension and media literacy in engineering freshmen's synchronous online writing course, and the relationships between the two variables. 'Scaffolding' is in-time support provided by a teacher/tutor or competent peer that enables students to meaningfully gain skills at problem solving process. Also, it is one of the most frequently mentioned concepts in education as well as one of the more necessary teaching strategies in an online writing course. In this study, provided treatments for the experiment were supportive scaffolding for domain-specific knowledge and reflective scaffolding for meta-cognitive knowledge. Participants were 102 engineering undergraduate students, who were assigned to two experimental groups by scaffolding types. A process-based writing course in online learning environment was conducted for 8 weeks. The writing tasks were given according to writing process. The findings were that, firstly, there were statistically significant writing apprehension's reduction and self-expression's improvement through the scaffolding provided in writing class. Secondly, writing apprehension's reduction and self-expression's improvement were significant in supportive scaffolding group. Thirdly, media literacy predicted writing apprehension. The practical implications of these findings are discussed herein, with particular attention on ways for writing apprehension's reduction as well as media literacy's enhancement.

This study is a questionnaire about the lesson environment that radiation major students prefer in a non-face-to-face live online lesson environment for a total of 133 students, 65 second graders and 68 third graders who are enrolled in the department of radiology at a university located in the Seoul metropolitan area. And checked the satisfactory level by grade. The questionnaire consists of three categories: 1st real-time non-face-to-face lectures, 2nd professor lectures, and 3rd corona lectures. A total of 14 questions, with multiple choice and descriptive response methods. As an evaluation method, in the case of a multiple-choice question, the average was calculated using a 5-point Likert scale. As a result of conducting the independent sample T-test of the SPSS program, the response by grade was P > 0.05, and no significant result was shown by the contents of the questionnaire survey of the second grade. As for the lecture method of the department of radiology after the end of Covid-19 virus, it is better to promote face-to-face lessons in radiation training subjects and non-face-to-face real-time education in subjects centered on radiation theory.

In this paper we propose an incremental classification of multi-class data set by LS-SVM. By encoding the output variable in the training data set appropriately, we obtain a new specific output vectors for the training data sets. Then, online LS-SVM is applied on each newly encoded output vectors. Proposed method will enable the computation cost to be reduced and the training to be performed incrementally. With the incremental formulation of an inverse matrix, the current information and new input data are used for building another new inverse matrix for the estimation of the optimal bias and lagrange multipliers. Computational difficulties of large scale matrix inversion can be avoided. Performance of proposed method are shown via numerical studies and compared with artificial neural network.
