The purpose of this study was to collect information for the improvement of sewing practice classes and to draw implications by carrying out an investigation into the perception and needs of 185 students in the first grade of high school for sewing practice classes. The results of the study are as follows. First, most of the students perceived that the instructional objectives of the practicum as the utilization in everyday life. The students' perception of the class was moderately positive. In terms of the subfactors, the participation level appeared to be the highest while the comprehension level was the lowest. Also, the utilization level showed the greatest difference between male and female students. The results suggest that female students were more positive in their perception of the class than the male students because of the significant difference in the subfactors of class perception, excluding utility and teaching learning method satisfaction. Second, it appeared that the students were likely to use these skills in everyday life as a result of the sewing practice classes. In terms of the practice content, students preferred working individually in terms of organizing their own projects, making their own selections, and freely deciding the size of their products. This study demonstrated that the students preferred teacher-centered classes when acquiring skills and knowledge and student-centered classes when brainstorming and performing the teacher's role. In terms of instructional management, the students preferred four to six 50-minute long lessons per semester and no group work involved.

무형문화유산의 전수 방식은 장인과 이수자의 직접적인 교육으로만 이루어져 왔으며 또한 전수는 긴 시간 동안 이루어지고 전수 방식을 따로 기록하는 경우가 드물며 동작이나 구전으로만 전해지기 때문에 표준화된 전수는 이루어질 수 없었다. 현재 국제 유네스코와 국내문화재청에서는 유무형문화재에 대한 전수와 기록의 중요성을 알고 다양한 디지털 기록을 진행하고 있다. 하지만 4차 산업혁명 시대에 무형유산 기록화 기술은 보유자의 기 예능 장인 공법을 기록하는 부분으로 영상기록 및 사진기록 도서 음원 등 아직까지 기존 아날로그 기술 방법으로 기록이 이루어지고 있으며 최근 5G 상용화와 함께 디지털 4차 산업 혁명시대와 발맞춰 무형유산 정보관리 기관에서도 무형유산 ICT 기반 기술 지원을 활성화되고 있는 시점에서 본 연구는 오랜 시간 동안 숙련도 높은 기술공법으로 한국 전통문화의 맥을 이어가고 있는 무형문화재 장인들의 기술 중에서 손을 사용하는 바느질 중심으로 자이로센서 기반으로 정확한 손동작 정보를 획득하고 기록할 수 있는 시스템 설계 및 연구개발을 통하여 ICT 기반 장인 공법 4D 기록화 기술을 제시하고자 한다. 이와 같은 기술로 무형문화유산의 새로운 4D 기록 방법으로 정확하게 기록하고 보존하여 무형문화유산 전승과 교육을 할 수 있고 문화유산의 유형에 맞는 교육·산업·홍보 등 다양한 사용 목적에 맞는 형태로 폭넓게 사용될 수 있다.

한국항공우주연구원 채연석(54) 원장은 어릴 때부터 로켓 만들기에 푹 빠져 있었다. 고교 시절 자작 소형 로켓이 귓가에서 터지는 바람에 고막을 다치기도 했다. 그 시절은 닐 암스트롱이 달에 인류의 족적을 처음으로 남기고, 미국과 옛 소련의 우주개발 경쟁으로 우주선 발사 장면이 연일 방송과 신문지상을 장식하던 때였다. 그것을 보는 소년 채연석의 꿈은 직접 만든 로켓을 우주로 쏘아 올리는 것이었다. 그로부터 30여 년이 지난 지금 채 원장은 한국의 우주기술 개발의 총 사령탑이 되어 있다. 그 자리에서 그는 우주를 향한 꿈을 바느질의 한땀 한땀처럼 엮어가고 있는 중이다. 한국항공우주연구원 원장실에서 만난 채연석 원장의 표정에서는 우주항공 기술의 기반을 쌓느라 영일없는 나날을 보내는 것을 금방 느낄 수 있었다. 채 원장은 2002년말 우주 개발용 로켓의 주류를 이루고 있는 액체연료를 사용하는 로켓을 개발해 발사에 성공하기도 했다. 그 로켓의 길이는 14m, 지름 1m로 우리 나라 독자 기술로 개발한 것이다. 그는 우리 나라가 독자적으로 인공위성을 만들어, 역시 독자적으로 개발한 로켓으로 발사에 성공하면 월드컵 4강 진출보다 더 국가 이미지가 높아질 것으로 내다봤다. 그만큼 우주기술은 극한 기술과 첨단기술을 골고루 필요로 하기 때문이다.

Composites are very useful material for light train carbody due to its high specific strength and lightweight characteristics. The composites, called 3-D board, are developed with a special stitching method. In this process, the glass fiber fabrics of skin material and foam core material are stitched together with glass fiber thread. The glass thread in Z-axis turns into FRP form. The conventional delamination problem can be solved with 3-D sandwich structure. In addition, with the lower density of foam, the weight of the panel and the operation expenses can be highly reduced. To evaluate the usefulness of the 3-D board, the double-deck light train carbody is studied. The stress analyses are carried out under various loads and boundary conditions with FEM Code, ANSYS. On comparing with the aluminum carbody, 3-D board carbody can be reduced by about 2 ton for the total weight of carbody.

The purpose of this study was to investigate the teachers' recognition on the optimization of the educational contents of Clothing & Textiles in subjects of :he Practical Arts or the Technology & Home Economics in the course of elementary, middle and high schools. The statistical data for this research were collected from 203 questionnaires of teachers who work on elementary, middle and high schools. Mean. standard deviation, percentage were calculated using SPSS/WIN 12.0 program. Also. these materials were verified by t-test, One-way ANOVA and post verification Duncan. The results were as follows; First, The equipment ratio of practice laboratory were about 24% and very poor in elementary schools but those of middle and high school were 97% and 78% each and higher than elementary schools. Second, More than 50% of teachers recognized the amount of learning 'proper'. The elementary school teachers recognized the mount of learning in 'operating sewing machines' too heavy especially, the same as middle school teachers in 'making shorts': the same as high school teachers in 'making tablecloth and curtain' and 'making pillow cover or bag'. Third, All of the elementary, middle and high school teachers recognized the levels of total contents of clothing and textiles 'common'. The 80% of elementary school teachers recognized 'operating sewing machines' and 'making cushions' difficult especially. The same as middle school teachers in 'hand knitting handbag by crochet hoop needle', 'the various kinds of cloth' and 'making short pants'. The same as high school teachers in 'making tablecloth or curtain'. Fourth, Elementary school teachers recognized 'practicing basic hand needlework' and 'making pouch using hand needlework' important in the degree of educational contents importance. Middle school teachers recognized 'making short pants unimportant. High school teachers considered the contents focusing on practice such as 'making tablecloth and curtain' and 'making pillow cover or bags' unimportant. My suggestions were as follows; Both laboratories and facilities for practice should be established for making clothing and textiles lessons effective in Practical Arts in elementary schools. The 'operating sewing machines' which were considered difficult should be dealt in upper grade, re-conditioning to easier or omitted. The practical contents should be changed to student-activity-oriented and should be recomposed in order to familiar with students' living. It was needed to various and sufficient supports for increasing the teachers' practical abilities.
