These days, It is very important to understand the knowledge about electronic products because most part of human life is connected with those. So in the 6th curriculum, there was the unit which called 'Make of an Electronic Kits' in Practical Arts education of elementary school. However, to make the electronic kits are very difficult to the 5th grade students and there is no practice room for making the electronic kits in most elementary school. So, many teachers are requiring the efficient teaching and learning materials of new type for this unit. This research is developing efficient teaching and learning materials of new type for this unit called Universal Electronic Kits Blocks. This Universal Electronic Kits Blocks is consisted of Pinclip, Pinclip Block, Base, Drawing board for picture of an electronic circuit and Electronic circuits. The students can make the electronic products easily by using this Universal Electronic Kits Blocks. By apply this Universal Electronic Kits Blocks to the schoolroom, we can get these results. (1) Easy achievement of the goals of teaching and learning for this unit by using the Universal Electronic Kits Blocks. (2) More easily understand of the picture of an electronic circuit according to arrange the electronic parts and lines to the same type with picture of an electronic circuit. (3) Easy repair of the wrong arrange of electronic parts. (4) The reduction of environment pollution by reusing of electronic parts. (5) More easily understand of functions of the electronic parts. (6) The reduction of experiment and training cost by reusing of electronic pars and Universal Electronic Kits Blocks. (7) The possibility of application of different level for teaching and learning according to the student's abilities and interest.

The organotypic raft culture model has been shown to be a useful method for examining the effects of biochemical manipulation on various epithelial cell types, using in vitro conditions that simulate the in vivo environment of the tissue of origin. To investigate this method as a model for photodynamic therapy (PDT), we cultures the oral squamous carcinoma cell line YD-10B on fibroblast-containing collagen gels at the air-liquid interface and assessed the efficacy of PDT using a photosensitiser 5-ALA-hexenyl ester. PDT effect on YD-10B organotypic raft cultures after twenty- four hours was determined. The number of residual cells was significantly reduced in comparison to control at all four different conditions. PCNA immunostaining and TUNEL assay revealed that PDT inhibited cell proliferation and increased apoptosis. These findings suggest that the organotypic raft culture model provides an effective and rapid laboratory method of investigating strategies for PDT on oral precancerous lesions and squamous cell carcinomas

Primary localized amyloidosis of the palate is a rare condition. We present a case of localized amyloidosis of the palate of a 49-year-old Korean female who suffered from asymptomatic nodular swelling. Microscopic examination revealed extensive deposition of pale eosinophilic amorphous material throught the lamina propria and within the walls of small blood vessels. A diagnosis of localized amyloidosis was made after the biopsy revealed characteristic staining on Congo red, and an extensive workup for systemic involvement was negative. Localized amyloidosis should be considered in the differential diagnosis of palatal nodular lesions

The Purpose of this study is to suggest the practical scheme for education field in the unit named 'Electricity・Electron into Life」 in Practical Arts Education in reorganized curriculum 2007. The contents of this study are about effective practical schemes for selecting teaching-learning contents, organizing textbook, teaching guidebook, and teaching-learning methods and materials. The study is going to interview teachers who previously have been teaching the unit 'Our life and Electricity・Electron' at 7th curriculum or who is in charge of Practical Arts Education. Teachers who participated the interview spoke his recognition and opinion about this unit. The conclusion of study is as follows. ⑴ On selecting the contents of unit, contents that grow up the students' creativity and practical work which is more easy to making are necessary. ⑵ Textbook must be conceived in the contents which increase students' interest and motivation of exploratory study. ⑶ For the teachers who lack the experience of making electronic kit, the teaching guidebook with more detailed explanation needs to be developed and supplied to teachers. ⑷ Video materials for effective guidance must be supplied considering shortage of teachers' teaching ability of practical subject. ⑸ Although the teachers see that the teaching-learning goal of this unit is high in some degree, suitable change in the contents, organization of textbook and teaching guidebook, and practical working environments can achieve the teaching-learning goal more effectively. 본 연구는 2007 개정 교육과정의 실제 현장 적용에서 초등 실과 ‘생활 속의 전기・전자’ 단원에 대한 내용의 선정, 새롭게 개발하게 될 교과서와 교사용지도서의 구성과 조직, 그리고 교수・학습 방법 및 자료 등에 대하여 효율적 실천 방안을 구안하는 것이 목적이다. 이 연구에서는 제7차 교육과정의 실과 5학년 ‘우리 생활과 전기・전자’ 단원을 지도한 경험이 있거나, 현재 실과 교과를 전담하고 있는 교사를 직접 면담하여 이 단원에 관한 교사의 인식과 견해를 묻고, 개정 교육과정의 효율적 실천을 위한 방안이 무엇인지 제안하게 하였으며, 이를 연구자가 정리하여 제시하는 방법으로 수행되었다. 연구 결과 다음과 같은 결론을 얻을 수 있었다. ⑴ 단원의 내용 선정에서는 학생들의 창의성 신장과 함께 어려움을 느끼지 않는 실천적 과제가 선정되어야 한다. ⑵ 교과서는 학생들의 호기심을 자극하고 탐구 학습 의욕을 북돋우는 형태로 내용이 표현되고 구성되어야 한다. ⑶ 전자키트 만들기에 대한 지도 경험이 부족한 교사들을 위하여 보다 상세하고 구체적인 설명이 가해진 교사용지도서가 개발되고 보급되어야 한다. ⑷ 교사의 실기 지도 능력이 부족하다는 것을 감안하여 이를 효율적으로 지도할 수 있는 동영상 자료 등이 제공되어야 한다. ⑸ 교사들은 이 단원의 교수․학습 목표 달성 정도가 어느 정도 높다고 하였지만, 내용의 선정, 교과서와 교사용 지도서의 구성과 조직에서 적절하게 변화시키고 이 단원의 실천 학습 환경을 적절하게 조성하여 실습의 완성도를 높인다면 보다 더 효율적으로 목표를 달성할 수 있다.
