독후감상문을 쓸 때에나 각종 생활문, 논설문을 쓸 때에 원고지를 이용하지만 많은 어린이들은 원고지 사용법이나 맞춤법에 익숙하지 않다. 어릴 때부터 한글 맞춤법에 대해 많이 공부를 하고, 교육을 받지만, 학교현장에서는 시간을 내어서 특별히 할 수 있는 시간이 많지 않기 때문에 또 다른 지도 방법이 요구되는 바이다. 따라서, 아동들이 원고지를 이용하여 스스로 맞춤법에 대하여 공부를 해 보고, 복잡한 기구 없이 좀 더 쉬운 방법으로 아동들의 한글 맞춤법 등 글짓기의 기능적인 측면을 지도할 수 있는 웹 기반의 원고지 첨삭지도 시스템을 설계한다.

본 연구는 프로그래밍 학습에서 교육용 로봇인 피코크리켓을 활용하여 동료지도학습을 실시하고 학업성취와 교우관계에 미치는 영향에 대해서 효과를 검증하는 실험연구이다. 프로그래밍 학습은 다양한 학습효과에도 불구하고 문법의 어려움과 학습내용의 어려움 때문에 그 효과를 제대로 발휘하지 못하고 있다. 그러나 교육용 로봇에서 사용하는 프로그래밍 언어는 입문자를 배려한 프로그래밍 방법을 사용하여 학습자가 쉽게 다가갈 수 있는 요소가 있다. 한편 프로그래밍 교육은 타 학습내용에 비해 수준별 학습이 더욱 요구되는 학습내용으로서 일제식 수업방법으로는 지도의 어려움이 많다. 따라서 본 연구에서는 교육용 로봇을 활용하여 프로그래밍 교육을 동료지도학습법으로 실시하고 이의 학업성취와 교우관계에 미치는 영향을 탐색해 보는 연구를 설계하였다.

This study is the case of non-face-to-face teaching-learning in the subject of "Research and Guidance on Early Childhood Materials" in the pre-child teacher training program. The study conducted a non-face-to-face teaching-learning model for 18 students at B University in region C who took lectures on 'Research and Guidance on Early Childhood Materials' in the first semester of 2021. As a non-face-to-face teaching-learning model, it consisted of video lectures, real-time zoom classes, and various forms of 'communication' through frequent feedback and interaction and 'participation'. As a teaching-learning strategy for the participation of pre-service early childhood teachers, comment on questions related to early childhood materials, in-depth reflection on early childhood materials through writing reflective journals and observation reports, and step-by-step presentation of making childhood materials plans, processes, and results were carried out. As a result of exploring the experience of making early childhood materials for pre-service early childhood teachers, factors such as "growth experience through trial and error," "thinking from child's point of view", "Increase efficiency and reduce burden through communication", "Process rather than result" and "The importance of communication and interaction in non-face-to-face classes"

In order to establish an independent relationship between occupations in accordance with the abuse of doctor's orders and employment, the position of each physician and medical technician group, and the education system and laws of Japan, the United States, and England To promote the improvement of public health. The main differences in positions among related interest groups were analyzed, and the proposals and precedents of the National Assembly laws that were initiated after 1963 were analyzed and compared with the laws of developed countries. Among the OECD member countries, 26 countries except Korea have enacted a single law for medical technicians, and the meaning of instructions and supervision differs from country to country. The Medical Technician Act, etc., is inappropriate to apply the current and situation of the times as the laws of the 20th century to represent all the laws of the eight medical technicians. It is thought that a change in the word of direction and supervision under the control of the company is inevitable from a future-oriented horizontal perspective.

The purpose of this study is to analyze the characteristics of teacher librarians' efficacy and to propose some ways to enhance their efficacy. To do this, questionnaires on 30 teacher librarians who participated in the level 1 certification program of K university in 2018 were conducted. The results showed that their average efficacy was 3.38, the efficacy of teaching method was 3.60, the collective efficacy was 3.38, and the personal efficacy was 3.18. They had high personal efficacy on classroom management, the willingness to lead poor students and the possibility of problem student guidance, and collective efficacy on conflict management with fellow teachers and parents. On the other hand, personal efficacy in problem analysis and guidance for problem students, difficult contents and course instruction were low. Also, the collective efficacy of the conflict between the manager and the education office was low. They have a strong willingness to improve teaching methods for students and showed high efficacy about student synchronization and preparation for teaching. However, they were aware of the lack of learning skills and the lack of various teaching methods. The variables influencing their efficacy were graduation, education level, school size, and degree. Especially, the higher the education level, the more confident and enthusiastic about teaching problemmatic students and disadvantaged students. In addition, teacher librarians with high academic standards showed high confidence in conflict resolution with peers and parents and teaching methods. The improvement direction to enhance their efficacy in this study are increasing the ratio of teacher education in the field of education, reforming teacher librarians training before appointment, establishing supervision organizations for school libraries and improving their professionalism by going to graduate school.

In GIS area, many line simplification algorithms are studied among generalization methods used for making the building data in the form of digital map from the original line data. On the other hand, there are few studies on the simplification algorithm considering the drawing rules of the digital map in Korea. In this paper, the line simplification algorithm based on the drawing rules is proposed as the methodology to create or update the building data of digital map by extracting the building outline from the CAD data used in construction. To confirm the usefulness of the algorithm, this algorithm and four other effective and general line simplification algorithms (e.g., Douglas-Peucker algorithm) are applied to the same building outlines. Then, the five algorithms are compared on five criteria, the satisfaction degree of the drawing rules, shape similarity, the change rate of the number of points, total length of lines, and the area of polygon. As a result, the proposed algorithm shows the 100% of satisfaction degree to the drawing rules. Also, there is little loss in four other mentioned criteria. Thus, the proposed algorithm in this paper is judged to be effective in updating the building data in digital map with construction drawings.

This paper verifies the performance of the wireless-signal map-matching (WSMM) method that is recently proposed to mitigate the effects of non-line-of-sight (NLOS) error in positioning under wireless terrestrial network environments. The WSMM method is the new positioning technology that estimates and compensate the NLOS errors by processing the bulks of anonymous measurements at unknown locations that are collected randomly and automatically. The WSMM method would be advantageous for various configurations of future ubiquitous sensor networks since it is based on the existing network configuration for communication and it requires no additional hardware in base stations and mobile handsets. It is shown that the application of the WSMM concept to the real CDMA pilot strength measurment message (PSMM) actually mitigates the NLOS error effects and improves overall positioning accuracy.

By comparing the development history of rectangular coordinate system in Cartography and Mathematics, we assert in this manuscript that the rectangular coordinate system is not so much related to analytic geometry but comes from the space perceiving ability inherent in human beings. We arrived at this conclusion by the followings: First, although the Cartography have much influenced to various area of Mathematics such as trigonometry, logarithm, Geometry, Calculus, Statistics, and so on, which were developed or progressed around the advent of analytic geometry, the mathematical coordinate system itself had not been completely developed in using the origin or negative axis until 100 years and more had passed since Descartes' publication. Second, almost mathematicians who contributed to the invention of rectangular coordinate system had not focused their studying on rectangular coordinate system instead they used it freely on solving mathematical problem.

Direct medical control by medical doctors is an essential part of emergency medical services system (EMSS). However, the indications are not specifically defined, even in 119 system with their own medical control team. The Seoul Metropolitan Fire and Disaster Management Department has operated internal medical consultation services on its own since January 2004. Based on the experiences from these services, we reviewed the cases of the direct medical consultation and establish the indications for direct medical control. And we presumed the demand of direct medical control with the established indications. The crews of 119 in Seoul made 793 calls to Medical Control Team during November 2004. We reviewed all of the calls according to the level of consciousness (AVPU), the kinds of emergency care done by crews during transport (10 categories), and the mechanisms of injuries (9 categories). The need for direct medical control was judged by authors with reviewing the records reported by the crews and control teams. Among 23 items, 14 items assigned as the indications, which were abnormal level of consciousness (VPU), 6 kinds of emergency care, and 5 mechanisms of injures. The sum of the three of them, 7,782 cases (45.9%), was in need of direct medical control. In conclusion, about half of the patients transported by 119 crews in Seoul require direct medical control. The need for the direct medical control in Seoul was estimated as many as 260 calls per day. To fulfill the need for direct medical control and to provide a effective medical control, the direct medical control should be accomplished through the communications between the crews and the medical staffs in the local hospitals.
