The purpose of this study was the reaching test of restorative glass according to composition. Mixtures of SrF₂, CaF₂and SiO₂were fused in platinum crucible. The glasses were ground and fraction which passed through a 400 mesh (38㎛) sieve were collected. The powder specimens were analyzed by a DTA and XRD. Then powder specimen were inserted to D. I. water with various of dissolution time and composition at 37℃. Fluoride ion, cation release, solubility, and pH change were estimated. It was clear that the glasses were formed except S0.65. In S0.40, Tg, Ts, and Tc were 630, 672, and 813℃ respectively. In initial 0.5 hrs., amounts of released fluoride ion and cation were about 90% of total released amounts and released rate was decreased with dissolution time. Amount of released fluoride ion and cation were increased with decreasing SiO₂ in glass filler. And released rate was decreased rapidly by adding CaF₂. This was caused by structural variation in glass filler. Solubility was similar tendency with ion released. The pH of D.I. water was 4.5. But in intial 0.5 hrs., pH was 8.2∼9.8., and decreased according to dissolution time. This is caused by ionic changing with cation and H* ion.

Kyung Sam Cho¹Si Young Kim¹, Jai Kyung Park²,Seung Hoon Choi³,Se Young Chung⁴, Hwi Joong Yoon¹¹College of Medicine, ²East-West Medical Research Institute, ³College of Oriental Medicine, ⁴College of Pharmacology, Kyung Hee University,Seoul, Korea. The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

외국어 습득 이론과 모형 : Krashen의 이론을 중심으로

김세중 단국대학교 1998 論文集 Vol.32 No.-

This is a study on second language acquisition(SLA) and English education focusing on the theory by Krashen. This area (SLA) can be said either a very brand new beginning stage or a polemic one unlike the field of first language acquisition. Because of this context researchers tried to accept the concepts and theories directly from that of the first language acquisition theory in the past. This attitude, however, has been perceived as mainly incorrect and then they began to change their way of thinking and now they are doing their job independently. In this article I briefly take a look at the chronological aspect of English education as a second or foreign language, and then I try to collect the related theories of SLA. Krashen's theory is one of these SLA theories. I pay attention to the advantage and disadvantages of the theory and on the basis of my knowledge, insights, and teaching experience I would like to release my academic critique on the theory in order to provide a better understanding of the classroom learning and SLA process. Anyway this paper investigates the effect of Krashen's theory on the SLA.

For the preparation of broad range of substituted aryl derivatives from the bromophenyl methoxymethyl sulfide and the bromobenzyl methoxymethyl sulfide, various functional groups such as alkyl, ester and haloketone could be easily introduced in the aromatic methoxymethyl sulfides by treatment with various electrophiles. Substituted methoxymethyl phenyl sulfides were converted to the arenesulfonyl chlorides with chlorine in water-dichloromethane at 5∼10℃. And substituted benzyl methoxymethyl sulfides were also converted to the arylmethanesulfonyl chlorides with N-chlorosuccinimide in aqueous acetic acid, at 5∼10℃.

도덕성을 지향한 과학교육의 정의적 접근

김기덕,윤세중 공주대학교 사범대학 과학교육연구소 1998 과학교육연구 Vol.29 No.1

과학의 발달은 인간 생활의 물질적 풍요와 생활의 편리함등 매우 긍정적인 기여를 해왔다. 그럼에도 불구하고 과학기술의 발달과 산업화 과정에서 발생된 공해 문제, 무절제한 대량 소비로 인한 자원의 고갈 및 환경 오염으로 인하여 지구는 황폐해졌다. 또한 가치관의 혼란으로 인한 인간성의 상실을 초래하게 되었다. 환경의 파괴와 인간성의 상실은 인간의 생존을 위협하고 있다. 자연의 질서는 인간의 잘못된 생각과 행동으로 파괴되고 그 결과 또한 인간에게 되돌려지기 때문이다. 이러한 부정적인 측면을 최소화하거나 해결하기 위하여 자연의 법칙에 따르는 도덕성을 강조하는 의식 개혁에 초점을 맞추는 수업이 이루어져야 할 것이다. 과학이 자연 속에서 객관적인 법칙을 찾아 자연의 이치를 밝히는데서 생겨났듯이 도덕 또한 자연 속에서 모태되었기 때문이다. 그러므로 과학은 자연이 인간에게 가르쳐 주는 길을 찾아 실천하고 또한 서로 보충하고 보완해야 할 것이다. 이렇게 함으로써 과학을 통하여 자연의 본질과 질서를 알고 자연의 법칙에 따라 생활하면 과학의 발전으로 인하여 발생된 여러 가지 부정적인 것을 최소화하거나 개선할 수 있으리라 믿는다. 따라서 본 연구는 도덕성을 지향한 과학 교육의 정의적 접근을 위하여, 자연의 법칙을 올바로 이해하고 이치를 깨달음으로써 해결될 수 있도록 중2 과정을 중심으로 지도안을 제시하였다. Scientific progress has had a remarkable impact on the items we use in our daily lives. In our rush for increased convenience and improved life styles the earth is being systematically destroyed. As we move into the 21st century out air is polluted, our oceans and rivers are pull of waste and our natural resources are running out. Because of our thoughtless quest for increased convenience, our country is in a state of social decay. Our thoughtlessness towards the environment is manifesting itself in our personalities and we seem to care less and less about one another every year. In our effort to decrease social decay, those classes which focus on the evolution of thinking should begin to emphasize elements of responsibility and morality towards our environment and towards fellow human being. Just as science gives us objective rules for the observation and illumination of our natural environment, morality helps us to taper those illumination with responsibility. The science teacher should include aspects of morality as a supplemental complement to his or her classes. If we know the essence and order of nature and act within established rules, any negative effects of future scientific progress will be significantly reduced.

30세 남자 환자로 심내막염 진단 후 발견된 무증상의 감염성 뇌동맥류로 항생제 치료 후 단계적인 수술로 심장판막 대치술과 뇌동맥류 결찰술을 시행하여 심각한 뇌신경학적 후유증이나 합병증이 발생하기 전에 성공적으로 치료한 경험을 하였기에 문헌 고찰과 함께 보고하는 바이다. Cerebral mycotic aneurysm is an uncommon complication of infective endocarditis. In spite of low incidence, mycotic aneurysm is a serious complication because of the high risk of its rupture. Therefore, early diagnosis and management of cerebral mycotic aneurysm are imperative before the rupture. We experienced a case of asymptomatic cerebral mycotic aneurysm in a 30-year old man with infective endocarditis. He was admitted for splenic and renal infarction due to systemic embolization. The echocardiography showed severe mitral regurgitation, mitral valve prolapse and vegetation on the mitral valve. Streptococcus mitis was identified from blood cultures. In the course of antibiotics therapy, brain magnetic resonance image and 4-vessel cerebral angiography were performed, which revealed multiple unruptured cerebral mycotic aneurysms. Considering the high risk of rupture we performed mitral valve replacement with bioprosthesis. On follow-up cerebral angiography after the valve replacement surgery, one of aneurysms was enlarged, and successfully treated by surgical intervention without complication. We report one case of mycotic aneurysm without neurologic symptom in an infective endocarditis patient, who was treated without serious sequelae of the aneurysm. (Korean J Med 64:477-481, 2003)

의미와 번역 : 영어와 한국어 수사 의문문의 비교 연구를 중심으로 A Comparative Study on Translating Rhetorical Questions in English and Korean

金世中 한국영어교육연구학회 1998 영어교육연구 Vol.- No.18

It is true that there are many problems, conflicts and difficulties with which the translator is confronted in the process of translation. In these viewpoints the end of this paper is to deal with "function" with due regard to contexts and extralinguistic elements other than the style and form of language, especially when translating rhetorical questions in English and Korean. This paper is concerned with the definition of a rhetorical question and the classification of the function of those in English and Korea in order to know what is needed for the reproduction and transformation of the source language text. In conclusion, it is, to say the least, necessary that the function of a sentence be transformed considering the extralinguistic elements in translating, since language has both the meaning of structure and that of society, culture and function.
