Recent studies say that informal learning is influential to students as much as formal teaming. Nowadays we can see various informal teaming inside and outside of the country. In 2004, it was the first attempt in Korea that engineer had gone to the elementary school fur activity that included scientific experiment and engineering work with students. National Academy of Engineering of Korea (NAEK) progressed activity with companies and elementary schools for students' making sense of engineer and what they are doing. To do that, NAEK had developed the network that company could support its local school's science education circumstance by engineers' visiting program. In 2004, seventeen companies including both large and small ones took part in the program called' Korea Junior Engineering Achievement (KJEA)'. In this program, engineers played the role of teacher (we call them company teacher), elementary school teachers played the role of organizing classes as a mediator. Elementary school teachers and company teachers' recognition is very important to make students' activity meaningful. The aim of this study was to give implication for informal science education activity for which engineers visit their local school. We got the result by survey and interview of company teachers and elementary school teachers. This study's result shows that almost company teachers and school teachers were in favor of purpose of this informal science education activity and satisfied with their participation. But some company teachers were not satisfied with worksheets, materials provided and relationship between school and company). Elementary school teachers and company teachers, both of them believed students' program as the key factor of success of informal science education activity. To make informal science education grow, school administrator and teacher need to have a will to utilize the activities more actively.

The purpose of the present study was to identify how and how much teachers utilize ICT in their instruction and to analyze teachers' perception about the environmental factors to promote ICT implementation after their participation in a teacher training for Project-Based Learning (PBL) with ICT. The results showed that there was a significant change in the application of PBL into classroom and the class preparation before and after the training. Lack of time to prepare the instruction using ICT was identified as the most important reason not to utilize ICT in their classroom. While teachers perceived time and rewards among the environmental factors were lack, dissatisfaction with status quo, incentives, knowledge and skill, participation and leadership were perceived as being present in their school.

The need to support the ICT-using teaching and learning at elementary and secondary schools has led to various digital content service systems. The systems are designed to target the teachers and the students as the major users. The problems involved in them is that they do not provide such services as the integrated search and the systematic use of interface in terms of actual users' use of teaching and learning digital content. It's because they have been created at demands at each time. In an attempt to solve this problem, this study set out to suggest the integrated meta-data items of a teaching and learning digital content, which reflects the Dublin Core Education, the international meta-data standard. It also aimed to design an entity-relationship model to realize the digital content. The results of the integrated meta-data and the entity-relationship model will be utilized as a basic research to help the users to search for various teaching and learning digital contents on an integrated basis and to realize a consistent user interface. Furthermore, they are expected to contribute to the development a service system the teachers and the students can make better use of.

쾌적하고 명료성이 높은 교실내의 음향환경은 학생들의 학업 성취도 및 교사의 언어전달 이해 향상을 이룩할 수 있는 중요한 사항이다. 이러한 우수한 교육환경을 위해서는 우선 우리나라의 교실 음향 실태 파악과 함께 교육시설의 음향상태 및 소음에 의한 학업 성취도, 심리적, 사회적 영향에 대한 정량적 조사가 이루어 져야 한다. 국내 교육시설의 음향 실태 파악을 통해 교육시설에서의 음향 및 소음 기준을 수립하여 교육시설내의 음환경 개선을 추진해야 한다. 교실 음향개선을 합리적으로 평가할 수 있는 지표로서 잔향시간과 배경소음이 가장 중요한 요소로 알려져 있다. 교실의 우수한 음환경을 위해 적절한 잔향시간은 $0.4\sim0.6$초, 배경소음은 NC-$25\sim30$수준이 확보되어야 하는 것으로 조사되었다. 또한 교사의 음성레벨과 배경소음과의 비(S/N비)는 최소 10 dB이상 되어야 강의 내용 전달이 가능하며, 각종 기계설비에서 발생되는 소음 및 진동은 저소음 기기 선정을 통해 최소화하여야 한다. 인접 실에서 발생되는 소음을 충분히 차단하기 위해서는 차음성능 우수한 구조의 벽계로 개선되어야 하며, 기밀성이 높은 출입문사용과 적절한 출입구 배치를 통해 인접한 교실로의 소음 전달을 최소화 할 수 있다.

Knowledge distillation (KD) is a model lightening technology that transfers the knowledge of deep models to light models. Most KD methods have been developed for classification models, and there have been few KD studies in the field of super-resolution (SR). In this paper, various KD methods are applied to an SR model and their performance is compared. Specifically, we modified the loss function to apply each KD method to the SR model and conducted an experiment to learn a student model that was about 27 times lighter than the teacher model and to double the image resolution. Through the experiment, it was confirmed that some KD methods were not valid when applied to SR models, and that the performance was the highest when the relational KD and the traditional KD methods were combined.

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.
