This is to investigate the posibility of home manufacturing of heavy chemical industry machines, such as rotary kiln, crusher, blower, cooler, electrostatic precipitator and weighing feeder of cement plant. It is concluded that even though we can not make all of them (some of them are made now and some others are going to be made in the near future, some of them are made whole and some others are made partially), we can build or export the cement plant by importing the important machines which we can not make now and by substituting them with ours gradually.

In order to investigate the relationship of body weight, body temperature and pulse rate to hypothyroidism in the state of uni-lateral thyroidectomy of Korean native goat, a brief observation was carried out. Twenty healthy male adult goats (7 months old) were used in the present experiment dividing into 2 groups, the control with 5 and the experimental with 15, respectively. Individuals of the experimental group were received uni-lateral thyroidectomy by surgical operation, while individuals of the control group, on the other hand, were received sham-operation. Measurements of body weight, body temperature and pulse rate after the operation were performed in duration of 48 days by 2 days interval. The results obtained could be summerized as follows. 1. There were no significant changes in body weight of experimental group compared to that of control group. 2. Uni-laterally thyroidectomized goat showed no changes in body temperature, which is seemed to he doe to a compensatory effect. 3. Statistical calculation did not show any difference in pulse rate between control and experimental group. The present experiment can he concluded that uni-lateral thyroidetomy had not any effect on the changes body weight, body temperature and pulse rate.

내구유연발수제에 관한 연구(Ⅳ) : 아크릴 공중합체를 주제로 하는 발수제의 P/C혼방직물에의 발수처리 Water Repelling Treatment of P/C Blended Fabrics with Water Repellents Based on Acrylic Copolymer

Separation, pressure and velocity distributions were studied fully developed two dimensinonal, incompressible flow over a flat airfoil in subsonic wind tunnel. Velocity and turbulence were measured with a two channel constant temperature hot wire anemometer and pressure with a pitot tube and pressure tranducer system. The experimental results were obtained as follow: (1) Turbulent intensity of shear layer just outside the separation point is considered to affect the size of separation bubble. (2) Static pressure coefficient is separated into three regions according to its value change. (3) Separation point is varied with the change of attack angle. (4) Velocity distributions and boundary layers normal to airfoil surface are changed as variation of attack angle of airfoil.

The purpose of this study is to research an effect of aggregate size on the compressive strength of concrete. Tests were, therefore, made in sixteen classes of concrete : maximum aggregate sizes of 5, 10, 20, 30^mm with water cement rations of 40% and 60% and with AEA°cement rations of 0.00% and 0.03% for each maximum aggregate size. The results of this experiment are showing the fellowing tendency. 1. Generally, with the range of this experiment program, the smaller maximum aggregate size becomes, the higher the compressive strength of concrete gets. 2. The decreasing tate of the compressive strength of concrete gets higher in lean mix concrete than in rich mix concrete at each age. 3. The compressive strength of concrete is developed faster with not only the increase of maximum aggregate size but also the decrease of water cement ratio. And it shows that the rate of the compressive strength development is higher in AE concrete in spite of water cement ratio.

An improved retinal tack can be used to fix the retina in complicated retinal detachment and proliferative vitreoretinopathy. We used the retinal tack made by biodegradable polyglycolic acid, polylactic acid and copolymers. The tacks with polyglycolic acid were placed in the retina the right eyes of 10 rabbits as group 1, with polylactic-polyglycolic acid copolymers as group 2 in each left eyes. We examined the absorption rates and degree of intraocular inflammation at 1 day, 1, 2, 4, and 8 weeks and compared both eyes. The tacks were absorbed with time in both eyes, but more rapid in copolymers. And there was no inflammation in both eyes. Now, this study will be a base on the drug delivery system in intraocular pharmacological and surgical management.

최경숙,박무림,정병학 圓光大學校 醫科學硏究所 2001 圓光醫科學 Vol.16 No.1-2

연구배경: 국내의 말라리아는 1970년대 말부터 근절되었으나, 1993년을 기점으로 급증하는 추세이어서, 이에 대한 역학적, 임상증상이나 경과 및 치료결과에 대하여 분석하고, 서구문헌과 비교해보고자 하였다. 방 법: 1998년 10월부터 2001년 8월까지 고열과 오한을 주소로 원광대학병원에 입원하여 말라리아로 확진된 28례의 환자들에 대하여 후향적으로 의무기록을 조사하였다. 본 연구결과를 토대로 서구의 연구결과와 비교하였다. 통계학적인 분석은 SPSS 9.0 통계 프로그램의 Chi-square test를 이용하였다. 결 자: 총 28례에서 원인원충은 전 례 모두 P. vivax이었고, 27례에서 발병 1년 이내에 전역한 경력이 있었고, 여자1례는 경기도 북부지역이나 외국여행의 경력이 없는 상태에서 진단되었다. 토착형 말라리아는 6월부터 10월 사이에 집중적으로 발생하였고, 고열과 오한(100%), 설사(14%), 오심이나 구토(35%), 심박수 항진(28%), 간종대(21%), 비장종대(39%)의 소견이 관찰되었다. 혈액검사상 평균혈색소는 12.4±1.8 g/dl이었고, 평균혈소판 수는 99,860±64,740/u1이었으며, 간기능의 이상을 보인 경우는 11례(39%)이었다. 혈뇨는 5례(18%), 총빌리루빈치의 상승은 10예(36%)에서 관찰되었다. 전 예에서 chloroquine phosphate를 3일간 1500 ㎎을 투여하고, 이후 primaqulne 15 ㎎을 매일 14일간 투여하여 28례 전 예에서 발열과 오한이 사라지면서 이상소견을 보였던 검사들도 정상화되어 가는 양상을 보였고, 치료중 나타난 약제의 부작용은 없었다. 서구의 Stanley 등의 연구결과와 비교하였을 때 빈혈, 백혈구 감소의 빈도가 더 높았다. 결 론: 최근 국내 말라리아의 발생은 급증하고 있어 이에 대한 적극적인 관리가 필요하고, 발열을 주소로 내원한 환자에서 반드시 말라리아를 감별진단하여야 한다. 또한 국내 토착형 말라리아에 대한 유전적인 소인 등의 연구가 추가적으로 필요할 것으로 사료된다. Background: Vivax malaria, which was once thought to be eradicable since more than 20 years ago, has made a dramatic resurgence since 1993 in the northern parts of Kyeonggi-do. We analyzed the cases of malaria who were treated in Wonkwang University Hospital with regards to epidemiology, clinical manifestations, and treatment outcome. Method: We retrospectively analyzed, clinical data of 28 confirmed cases of malaria treated in the same hospital from October, 1998 to August, 2001. We also compared out data to meta-analysis reports from western contries. Results: Twenty-eight cases of malaria were enrolled. All cases were diagnosed as vivax malaria. All 28 patients had fever and chills. Hematologic abnormalities were the most common laboratory findings. Our patients showed anemia, thrombocytopenia, leukopenia and elevation of transaminase more frequently than western patients. Conclusion: The number of malaria cases has been increasing by year. Early diagnosis, treatment, and prevention of malaria are important. To prevent indigenous malaria, anyone who travels to endemic areas should receive proper education and chemoprophylaxis, considering the pattern of drug resistance. Further genetic studies are desired to determine the subspecies of plasmodium vivax.
