Jong Hyuk Kim. 1997. Restoration of Degradation Phenomena of Ecosystem and Language Culture. Collected Papers on Christian Language Culture. The degradation phenomenon of ecosystem is regarded in this study as an event of disclosure of the technological societal resolution of human problems. The elementary cause of destructive phenomenon of ecosystem is disruption of the balance of the world of nature through a radical or one-sided technological intervention. The one-sided intervention with nature is due to the unique mode of the scientific-technological resolution of human problem. In this study the speech-thinking allowing us with creating language-culture is regarded as an alternative and creative resolution of human problem. The speech-thinking introduced as a new method of social science has a number of positive elements, such as the power for creating a new community through the dialogical speech and communion. The speech-thinking guides us with wholistic reason and an appropriate guide for a creative resolution of the destruction of ecosystem of the world of nature. (Advisory Researcher of the Institute)

『구입유물공개전』 전시유물 보존처리 : 금속유물을 중심으로

권혁남,이용희,김종오 국립중앙박물관 2000 박물관보존과학 Vol.2 No.-

국립중앙박물관에서는 국내외에서 구입한 유물들을 전시하기 위하여 보존처리를 실시하였다. 처리유물은 금속제 유물을 비롯하여 목제, 회화, 목·칠기 등 다양한데, 이중 금속유물 42점의 보존처리 내용을 재질별로 소개하였다. 유물의 현재 상태를 파악하기 위해 현미경 조사 및 X-선 촬영을 실시하였으며 재질에 따라 이물질 제거 방법, 안정화 처리 방법 등의 처리 방향을 설정하였다. 또한 역사적 자료를 보존하고 일반인들에게 전시할 수 있는 조치를 취하였다. For exhibition, conducted conservation treatment for a variety of collections acquired at home and abroad such as metallic objects, wooden-ware, paintings and lacquer-ware. Conservation treatment methods for 42 metallic objects were introduced for material types. X-ray and microscopic method were used to identify the current state of the collections and in some case if necessary, various foreign particle removing and stabilization method were used depending on material type. Historical data were stored and exhibited to public.

Retinoic acid에 의해 유발된 흰쥐의 구개열에서 Transforming Growth Factor-beta 1, 2, 3의 발현의 변화

김종환,박진혁,신선호,윤혜경,김우형,이희철 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.4

Objective : Craniofacial malformations are among the most frequent congenital birth defects in humans : cleft palate, that is inadequate fusion of the palatal shelves. Retinoic acid is teratogenic in many species, producing multiple malformations, including cleft palate. Also it plays an important role in embryogenesis, by regulating morphogenesis, cell proliferation, differentiation, and deposition of the extracellular matrix. The effects of retinoic acid which leads to cleft palate vary depending on the stage of development exposed. After exposure of embryonic mice to retinoic acid on gestational day(GD) 10, abnormally small palatal shelves form. And the elevation of palatal shelves is delayed. The growth and differentiation factor, transforming growth factor-beta(TGFβ) family is thought to play important roles in multiple developmental processes, especially, the development of the embryonic palate. The expression of the TGFβ family in embryonic palate suggests a functional role for these molecules. In this study, author has determined the tissue distributions of TGFβ family in murine embryonic palate, and compared them in terms of developmental stage and locations in normal and retinoic acid-induced cleft palate. Methods and Material : Retinoic acid was administered orally at gestational day(GD) 10 to ICR mice. The pregnant mice were sacrifeced on GD 12, 13. 14, 15 to obtain the fetuses and immunohistochemistry was performed. And using the scanning electron microscope, morphology of normal palate and cleft palate was studied. Results : In the retinoic acid-treated fetuses, palatal shelves did not elevate and cleft palate was induced. On GD 13 in the palates of the retinoic acid-treated fetuses, expression of the TGFβ1, 3 decreased dramatically, but that of TGFβ2, did not change. The expression of the TGFβ1, 3 in the palates of the retinoic acid-treated fetuses, increased on GD 14, 15, Significant differences in TGFβ family expression were observed with areas of the palate. Conclusion : These results suggest that retinoic acid inhibits the expression of TGFβ 1, 3, which is critical in the developing palate, and elevation of palatal shelves is delayed and impaired, therefore cleft palate is induced. These data demonstrate a role for retinoic acid and retinoic aicd-induced TGFβ family in the regulation of palatal development and suggest a role for TGFβ in retinoic acid-induced cleft palate.

4채널 원통형 정전용량 변위센서의 자동ㆍ정밀 검보정

General purpose of cylindrical capacitive displacement sensor(CCS) is measuring run-out motion and deflection of rotor. If CCS has narrow sensing range, its sensitivity coefficients must be calibrated precisely. And x, y component of CCS output can be coupled. In this research, CCS calibration procedure is automated with automatic calibration program and PC-controlled stage. And, coupled-terms of CCS signals were removed and the errors between measured position and mapped CCS signal were reduced obviously by sensitivity matrix that linearly

The purpose of this study was to develop and identify the effects of portfolio materials for performance assessment on the unit of wooden ware making practical arts in the primary school. In this study, the researcher was analyzed the literatures which was related to portfolios, and created the elements and items of performance assessment, and developed portfolio materials. The results of the study were as follows: (1) After the portfolio materials of practical arts applied to lesson of the woodenware making unit, the results of learning achievement test showed a level by averages 80.8%. The portfolio materials improved the efficiency of performance assessment, and effected on the increasing performance ability in practical arts. (2) After using portfolios, in the results of the learning attitude test of students, seven items of affective domain consist of pleasure during the practical arts education, value of nature, attitude of using tools safely, feeling of satisfaction in the result of practices, confidence in the working of wood-working tools, continuous practice of the practical exercise, attitude of make and using goods of life, which used portfolio materials effected on the increasing learning achievement level.

切削加工에서 다듬질面의 粗度에 미치는 影響에 關한 硏究

李鐘赫 忠州大學校 1993 한국교통대학교 논문집 Vol.28 No.-

I have studied on the effects of applied tools wear and intensity of illumination according to each condition which were changed cutting speed, feed and cutting depth for using carbide tools, carbon steel for machine structural use. I have abtained conclusion as followings; 1. I have confirmed again on the effects of applied illumination surface according to cutting speed, feed and cutting depth when work materials are in need of finishing precisely face. 2. It I have less made feed motion intensity of illumination was increased, the more cutting work of time is long the more chattering happened a primary of factor. 3. Even if cutting depth was a number increased, it was not accepted on the effects of applied intensity of illumination.

Urechis unicinctus 난세포의 인공수정에 의한 구조적 변화

권혁제,김완종,신길상 순천향대학교 1994 논문집 Vol.17 No.3

The artificial insemination in Urechis unicinctus oocyte revealed some fine structural changes under electron microscope. The degradation of surface coat, retraction of microvilli, fusion of cortical granules with oocyte membrane are the events of fine structural changes after the fertilization. At fertilization, the cortical granules of oocyte are transported from the inner cortex toward oocyte membrane. After the fusion, the contents of cortical granules are discharged into the perivitelline space, the extracelluar space which in future develops into fertilization membrane. There are some indications that the fertilization occur on the microvillous tip in U. uicinctus. Under light microscope, one of the evidences on the fertilization was the formation of fertilization cone, which seemed to sperm entry site, on membrane of round mature oocyte.
