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.

The paper selectively examines the study by reviewing the characteristics of the various finacial instruments on the basis of the cash flows of venture business life cycles. I suggested the source of capital matrix combining the various sources of capital. At each stage, the venture businessess should raise the funds by using the various combinations of sources of equity financing and debt financing.

우리나라 海成粘土의 壓密常徵에 關한 硏究

金振勳,朴在云 관동대학교 1991 關大論文集 Vol.19 No.2

It is generalized that the compression index of soft soil is the main parameters to calculate the settlement. To determine the parameters, we must take consolidation test in the laboratory, but the test is very difficult becaue of sampling, disturbance, etc.. An account of this reason, many reporter have studied to identify the relationship between the compression index and the other soil properties except consolidation test method. The investigation described in this paper are to analyze the correlation between the compression index and the other soil properties fur the Korean marine disposit clay and to compare the previous report. With parameters and mathematical models being changed, experimental equations were obtained by regression analysis in which a personal computer was used.(Minitab statistics package) The analyzed result for 413 undisturbed samples have shown that the compression index is related to liquid limit, in-place ratio, and natural moisture content. The result forms this study are as follows: ??

We reviewed 61 consecutive eyes recently subjected to vitrectomy to determine the incidence and outcome of iatrogenic retinal tears. Iatrogenic retinal tears occurred in 14 eyes(22%). 14 eyes had 22 iatrogenic retinal tears. The incidence of iatrogenic peripheral tears was 6% and of posterior tears was 16%. Two thirds of tears occurred in the inferior quadrants. 43% of iatrogenic retinal tears occurred in patients with proliferative diabetic retinopathy. The overall anatomic success was achieved in 10 eyes(71%), 9 eyes of which were successfully treated with the initial operations. With a combination of intraocular gas tamponade, laser photocoagulation, cryopexy, or scleral bucking, 71% of iatrogenic retinal tears were successfully treated.

본 연구는 신제품 개발이론에 대한 이론적 틀을 연구하고, 이에 기초하여 석재복합 관련제품의 신제품 개발 노선, 기술, 신제품 개발전략 구축과 선택 방안을 제시하였다. 석재복합 관련 제품의 대부분은 첨단 고도기술을 필요로 하는 영역이 한정되어 있기 때문에 이 산업 분야에서의 신제품 개발은 신제품 개발계획과 지침을 마련할 필요가 있다. 또한 유망 신제품 안건으로 계층화하여 신제품 개발의 기본전략을 구축하는 신규사업 시나리오를 작성하여 신제품 개발전략을 구축하는 것이 효과적이다. 이러한 과정을 거쳐 중소기업의 경우는 현존하는 시장, 제품, 그리고 기술우위에 기반을 둔 신제품을 개발할 경우 성공 가능성이 클 것이다. 이 이외에도 석재복합제품 개발은 석재자원과 신소재 개발에 기초한 신제품 개발에 필요한 기술 진전 사항, 즉 기술개발-제품개발-시장진입 활동간 상호 연계성을 고려해야 한다. This study suggests the theoretical framework and strategy of new product development in the avdanced mineral aggregate composite industry. The advanced mineral aggregate composite area needs to prepare the plan and guidelines on the new product development owing to the characteristic of the related technology. Alternative scenarios on the hierachy of new product idea is effective to the success of new product development strategy. Especially, the existing market, product, and the technological advantages affects the possibility of the success of new product development of the small firms. Also considering the interrelationship between the technological trends is important to the new product development of advanced mineral aggregate composite industry.

For extension of storage with Cheju grown potatoes, irradiations with doses of 5 Krad. 10 Krad and 15 Krad were applied and the differences of quality were compared between the irradiated and the unirradiated and also between doses. Irradiation is not effective on the prevention of decaying. Irradiation of 5 Krad is too low compare with 10 Krad and 15 Krad and 10 Krad is more effective and energy saving than 15 Krad. Among same irradiation doses, outdoor storage showed better quality than those stored in enclosed space in the room.
