To produce well-qualified medical doctors, clinical training is a crucial part of medical education. To this end, teaching hospitals should be carefully selected and professionally managed. However, in Korea, there are no regulations or standards for training hospitals. Instead, some of the regulations that target teaching interns and residents are applied to teaching hospitals. In this study, we reviewed standards and regulations for training hospitals in other countries as a basis for proposing new standards for teaching hospitals in Korea. These new standards take into account the current environment of Korean medicine with the aim of designing appropriate educational programs for students and professional development systems for professors as well as providing educational resources and addressing the local community and international exchange opportunities.

In order to improve the energy efficiency of n-Epidemic routing protocol in opportunistic networks, in which a stable end-to-end forwarding path usually does not exist, a novel adjustment strategy for parameter n is proposed using learning atuomata principle. First, nodes dynamically update the average energy level of current environment while moving around. Second, nodes with lower energy level relative to their neighbors take larger n avoiding energy consumption during message replications and vice versa. Third, nodes will only replicate messages to their neighbors when the number of neighbors reaches or exceeds the threshold n. Thus the number of message transmissions is reduced and energy is conserved accordingly. The simulation results show that, n-Epidemic routing protocol with the proposed adjustment method can efficiently reduce and balance energy consumption. Furthermore, the key metric of delivery ratio is improved compared with the original n-Epidemic routing protocol. Obviously the proposed scheme prolongs the network life time because of the equilibrium of energy consumption among nodes.

Polishing a die that has free-form surfaces is a time-consuming and tedious job, and requires a considerable amount of high-precision skill. In order to reduce the polishing time and cope with the shortage of skilled workers, a user-friendly automatic polishing system was developed in this research. The polishing system with five degrees of freedom is able to keep the polishing tool normal to the die surface. The polishing system is controlled by a PC-NC controller. And, to easily onerate the developed polishing system, this stud)r developed a integrated program in the Windows environment. This program consists of 4 modules: polishing module, a graphic simulator, a polishing data generation module, and a teaching. Also, the automatic teaching system was developed to easily obtain a teaching data. The developed teaching system consists of a three dimensional joystick and a proximity sensor. In order to evaluate stability of the driving program and the leaching system, polishing experiments of the die of saddle shape were carried out.

Purpose: This study was performed to explore the effect of the delivery format on teaching presence, learning presence, and learning outcomes in distance learning of nursing students. Methods: A descriptive survey was conducted to understand teaching presence, learning presence, and learning outcomes depending on the delivery format of distance learning. Quota sampling methodology was used to recruit 295 nursing students from all over the country, and data collection was done from July 27 to September 10, 2020. The first delivery format for distance learning was synchronous learning in which communication between the instructor and students occurred simultaneously. The second delivery format was asynchronous learning in which prerecorded videos were provided and communication did not occur simultaneously. Results: In synchronous learning, teaching presence (especially direct facilitation) and learning presence (especially emotional expression) had a statistical significance that was higher than in asynchronous learning. However, in learning outcomes, there was no statistically significant difference. There were significant positive correlations between teaching presence, learning presence, and learning outcomes, and there were significant positive correlations. Conclusion: It can be suggested that learning outcomes can be improved if presence is improved in the distance learning environment based on the results of this study. It is necessary to add contact with nursing students and instructors to improve teaching presence in the asynchronous learning, and it is necessary to help students express their emotions to improve learning presence.

In this paper we give a description of students' obstacles in their learning of geometry, especially resulted from their confusing a physical drawing with a figure, a geometrical object which a physical drawing represents. In computer-based teaching-learning environment, we could relieve such obstacles through providing students for experiences in which they must focus on elements of a figure and relations of them. But there may be potential in computer-based environment if we offer students only visual experience for validity of geometrical gacts: students' lack of understanding for need of proof and experience of cognitive obstacles which is very important for students to reflect their thinking and activities. Thus an didactical treatment must follows, which we also give an example.

We have created in our university material management environment, which uses database created by using LATEX-files, and LATEX2HTML translator and PHP language. In this paper we will define how these LATEX-files are transformed into our database. In this paper, we present work which we have done for providing the material used in the teaching of calculus to students at Lappeenranta University of Technology. This procedure can be divided into three separate steps: 1) creation of the LATEX-files, 2) implementation of these LATEX-files in 3) conversion of the base LATEX-files to the HTML-files. So far, we have stored hundreds of exercises with hints and solutions on our web server in addition to some theory that we felt is necessary for the students. In this paper we will also discuss the benefits and future of our functioning Web-environment [1].

The purpose of this study was to analyze the stresses of teachers for elementary science class. To do these, the Science Teacher Stress Inventory has been developed the Science Teacher Stress Inventory, which consisted of 45 stress factors with subcategories such as student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures. 120 teachers for elementary science class have participated in this questionnaire survey. The results of this study are as follow: First, stress from teacher characteristics is perceived as having more stress factors than five stress factors (student characteristics, teacher characteristics, expertise of science education, school environment, and administrative procedures). but all of the five stress factors was under normal. The detail question of stress such as 'Having to guide educational guidance and course in life education', 'Having to cope with the demand of new curricula', 'Pace of the school day is too fast', 'No time to attend training of the experiment (preliminary experiment)', 'Not enough time to complete lesson preparation and marking', 'Having to cope with non-teaching delegated duties', 'Fear of getting injured as a result of lab accidents' are perceived as having a lot of stresses. Second, there were not statistically significant differences in their personal variables such as gender, the course of high school. but there were statistically significant differences in their personal variables such as whether elementary subject exclusive science teacher, career in education experience, teaching grade. Third, coping ways of stresses are active support for better science teaching conditions, training of the experiment for expertise of science education, developing a workbook for science class.
