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 prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

In this paper, the performance and functions of automatic flatness control system installed on the 4 hi-reversing mill and has been investigated under actual conditions. A new automatic flatness control system incorporates a measuring roll for measurement and correction calculations, hydraulic roll benders, selective roll cooling, and a programmable controller forinterface and data logging. The test results are as following. The more the exit steel strip thickness is thick, the smaller the I value, and the more it is thin, the larger the I value. And, a complex distribution of strip tension was controlled, for example, not only a quarter buckle but also a simple center wave and edge wave. Because the tension deviation is larger at acceleration speed and deceleration speed than steady speed. so automatic flatness control system of contact type is better to adopt over 450 m/min, automatic flatness control system reduces rapidly large flatness deviation. The maximum I value of strip has been decreased to 13 I, and defects caused by poor flatness have been drastcally decreased. And coolant temperature for work roll cooling system on the automatic flatness control system is better to adopt about 50-55℃.

자동 형상제어용 측정롤의 특성에 관한 연구

The continuing demand for quality products requires better understanding and improved control of the production process. And, in recent year requirements for flatness control in strip rolling have become increasingly severe because of the control for flatness of cold rolled strip is essential for further down stream processing. Also a speeds of rolling mills to meet productivity requirements puts a demanding requirement on the control of flatness of rolled strip. The demands on a total flatness control system therefore are a measuring and indication system consisting of a measuring roll that is robust, accurate, reliable and require a minimum of maintenance. The critical part of any control system is the quality of the information being provided by measurement instrument or device. It is therefore of utmost importance to have an accurate, repeatable measuring system.

Gelman과 Gallistel의 수세기 이론에 기초한 유아수학교육방향 : 사회극놀이를 통한 유아수학교육프로그램 활동제시

김영중,김경희 제주관광대학 2003 論文集 Vol.9 No.-

유아기 수학교육은 생활 속에서의 경험을 재구성하여 수학적 사고와 의사소통이 이루어질 수 있도록 해야 한다. 그런데 유아의 수학적 사고발달과 학습과정, 그리고 다양한 교수방법에 관한 연구결과를 바탕으로 보다 바람직한 유아수학교육의 방향을 제기하는 이론적 동향과는 달리, 많은 유아교육기관에서의 수학교육은 매우 제한되거나 적합하지 않은 방법으로 이루어지고 있다. 이에 본 논문에서는 최근에 보다 타당하고 적합한 것으로 공감을 얻고 있는 Gelman과 Gallistel의 수세기 이론에 기초하여 바람직한 수학교육의 방향을 제시하고 실제로 유아교육현장에서 적용 가능한 활동내용과 방법을 제시하고자 한다.

The purpose of this study is to investigate into the physical properties of Li₂O-Al₂O₃-nSiO₂ (LAnS) system of crystallized glass prepared by sol-gel method according to the composition ratio of LAnS. In order to find the crystallization temperature as well as the state of crystalline, differential thermal analysis and X-ray diffraction analysis were examined. The results obtained are as follows : 1. Gelling time became longer as increasing the composition ratio of SiO₂ and also found that it became faster as increasing the additive amount of water. Also, additive amount of water required for the gellation was above four times of the theoretical amount of water required hydrolysis. 2. Surface area and mean pore size became larger as increasing the composition ratio of SiO₂ and for LA4S dried gel, surface area was 331.1m^(2)/g, mean pore size distributed about 5nm and 30-50nm. 3. The crystallization temperature is high as increasing the composition ratio of SiO₂ and for LA4S, crystallization temperature is 800℃. Also, LA4S formed at 800℃ for the crystalline phase of β-eucryptite and at 900℃ for crystalline phase of β-spodumene.

This paper presents a new magneto-thermal finite element analysis for predicting the temperature rise of the EHV GIS bus bar. The power losses of a bus bar calculated by the magnetic field analysis are used as the input data to predict the temperature rise for the thermal analysis. The heat-transfer coefficients on the boundaries are analytically calculated by applying the Nusselt number considering material constant and model geometry for the natural convection. The temperature distribution in a bus bar by coupled magneto-thermal finite element analysis shows good agreement with the experimental data.

Background: This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates Methods: We reviewed 262 death certificates in three hospitals from March 1 to April 30, 2000, and 119 death certificates in one hospital from March 1 to 31, 2000. We identified major and minor errors and analyzed and compared them retrospectively. Results: A total of 381 death certificates were reviewed: 59 in Seoul National University Hospital,101 in Ewha Woman's University Hospital, and 102 in Gachon Medical College Hospital, which has no education program for completing death certificates in postgraduate training, and 119 in Samsung Medical Center which has an education program for completing death certificates. 358 certificates(94.0%) had at least one error. There were only 23 death certificates(6.0%) without an error. In 182 cases(47.8%), there was one major error. In 321 death certificates(84.3%), there were more than two errors. A comparison of Samsung Medical Center with the other hospitals showed that the number of total errors was statistically different(p=0.001). Conclusion: There were few death certificates without an error in this study. In a hospital which has postgraduate training in completing death certificates, there are fewer errors than in other hospitals which have no training course. Emergency physicians actually certify many deaths, so they must know the correct method of completing death certificates for statistics on morbidity and mortality.
