수업의 핵심이라고 할 수 있는 교사의 교수법 향상을 위해서는 실제 수업을 잘하는 사람의 수업 장면과 교수 학습 지도안을 보고 동료교사 및 전문가들과 같이 수업에 대해서 같이 토론하는 것이 좋을 것이다. 그러나 현장의 교사들에게는 실제 그러한 참관 기회가 많지 않을뿐만 아니라 참관 및 토론의 환경도 충분히 제공되지 않고 있다. 이러한 문제점을 해결하기 위한 방법으로 실제 교수법이 뛰어나 교사의 수업 장면을 동영상으로 제작하고, 이 동영상과 교수 학습 지도안을 동기화시킨 전자 지도안을 만들어 현장 교사들에게 제공하는 것이 좋을 것이다. 본 연구에서는 교수법 향상을 위해 저자 지도안 재작 도구의 프로토타입을 개발하였다.

The purpose of this study was to provide the basic data needed for developing comprehensive child edu-care programs that fits the regional needs. Subjects of the survey were the teachers of child edu-care centers in Daejeon. 95 teachers were selected from 20 child edu-care centers, using stratified random sampling method, from all of five municipal districts of the city. Gathered data were analyzed using SPSS 10.0 for reliability, factor analysis, frequency and percentile, mean, standard deviation, paired samples t-test and F-test. The summary of the findings were as follows: First, the result of survey on the child edu-care facts showed that the most child edu-care centers had the focus on caring and education programs of children, while emotional supports for family services and community social services were rather secondary importance. Therefore, to achieve the comprehensive service programs, child edu-care services should be harmonized by the education and welfare approaches. Second, centered around teacher's request, comprehensive child edu-care program that fits the regional characteristics focuses on family service; thus the program requires family group consulting, parents education etc., as well as focusing on community service to utilize local community's human, physical resources and to strengthen the tie between local community and child care services.

The attraction force is an important parameter for permanent-magnet(PM) linear machines. This paper aims to analysis lumped magnetic circuit model of a magnetic levitation system. It accounts for the fringing effect and leakage flux which may greatly affect the accuracy of the analytical model for the optimal lumped magnetic circuit model. consequentially it will be able to apply to prospective permanent-magnet(PM) linear machines for accurate analysis.

The purpose of this research is to investigate the current status of edu-tech trends and contents of domestic and foreign private companies in order to successfully establish the K-EDU integrated platform, analyze the connection between future teaching-learning methods and learning styles, and provide basic materials to help frontline schools easily link teaching-learning methods to the most suitable contents per subject. To this end, a literature survey and on-site interviews with officials from companies participating in the 2021 Education Fair provided results of investigating 116 edu-tech contents produced by a total of 68 companies, including 22 overseas (28 contents) and 46 domestic (88 contents) ones, on whether they mutually match future teaching-learning methods and learning styles.

Ultrafiltration has been performed to separate proteins, which is almost unique method of protein separation in mass production scale. The problems of its low selectivity and decline in permeation flux resulted from gel formation on the membrane surface have been greatly improved by an applied electric field across the membrane. The applied electric field promoted or hindered the permeation of protein through membranes depending on the electric charge of protein molecules in aqueous solution. With the effects of electric field, the permeation flux and the selectivity of the ultrafiltration could be improved significantly.

As the school was in crisis due to the COVID-19, e-Learning was extended. Although it was difficult for everyone, e-Learning were stabilized with the enthusiasm and efforts of school teachers. Online education in Korea, called 'K-edu' is being promoted by school teachers in COVID19, and is considered an important area of future education beyond the post corona. Therefore, analyze the meaning of K-edu experienced by school teachers, studying changes in the educational paradigm in the Post-COVID era is very important in establishing the direction and content of future education. In this study described the K-edu experienced by school teachers in response to Corona 19 as 'changed daily life of school teachers', 'changes in schools', 'difficulties felt by teachers' and 'proposals for K-edu' through the qualitative research method FGI. Based on this, the characteristics of K-edu that changed through COVID-19 were analyzed as 'expansion of educational space', 'expansion of educational form' and 'highlighting the importance of face-to-face education'. Through this study, we hope that K-Edu led by school teachers will serve as a cornerstone for leading the world beyond Korea.

In school education, mathematics is obviously an independent subject. But the function of mathematics is revealed when it is joined with other subject. For example, when we use mathematics to solve a scientific problem, we can clearly feel the function of mathematics and its roll for science. So, it is general to teach the functions of mathematics by dealing mathematical application. For this method, student mostly pass over that because mathematics is only a tool. Therefore, it is necessary for mathematics part to be separated from mixed application. In this paper, we present a model to contain such an effect.

The antimicrobial activities of extracts from some of natural products and bacteriocins produced from lactic acid bacteria such as L. mesenteroides, L. citreum and P. pentosaceus have been investigated with using disc diffusion assay, challenge method and minimum inhibitory concentration method. The bacteriocin substances produced from L. mesenteroides, L. citreum and P, pentosaceus have shown strong antimicrobial activities against E. coli, S. aureus, P. aerugionosa, and B. subtillis while the extracts from phenonip and sandal wood have shown strong antimicrobial activities only against C. albicans. The bacteriocins produced from L. mesenteroides, L. citreum and P. pentosaceus could be a promising preservatives for cosmetics, pharmaceutical products and foods in future.

Optical disk drives read information by replacing a laser beam on the disk track. As information has become larger, the more accurate position control of a laser beam is necessary. In this paper, we report the analysis and fabrication of the micro mirror for optical disk drivers. The mirror was fabricated by using MEMS technology. Especially, the Process using the lapping and polishing step after the bonding of the mirror and electrode plates was employed for the process reliability. The mirror size was $2.5mm{\times}3mm$ and it needed about 35V for displacement of $3.2{\mu}m$.
