The Korea Research Foundation(KRF) has supported the research activity of the academic society through 'Conference Grant Program' and 'Journal Publication Subsidy program'. The purpose of this paper is to reconsider this existing KRF' support programs for the academic society by analyzing the actual condition of foreign research foundations' aid for their academic society. To find implications, this study analyzes three countries' research foundations cases: Japan Society for the Promotion of Science (JSPS), National Science Foundation (NSF), National Endowment for the Humanities (NEH), American Council of academic Societies(ACLS), and Deutsche Forschungsgemeinschaft (DFG). Data of this study collected through related research publications, internet, and interview with the persons concerned of JSPS and DFG. Based on the findings, some implications for formulating a support program for the research activity of the academic society can be suggested as follows: First, the category 'promotion of publication of scientific research results' in Grant-in-Aid for Scientific Research in JSPS was designed to provide support to the academic society of Japan. In spite of this support, the FY 2000 amount for this progam was 2.59% in JSPS' total grant. NSF, NEH, ACLS, and DFG have give no support to the academic society itself. As a general principle, a academic society of Korea like that of the United States and German is required to meet its expense through membership fee. But considering Korean academic society's financial difficulty, it is necessary for KRF to support the research activity of academic society for a time. Second, it needs to publish chargeable scientific periodicals for academic society's self-supporting. In addition, like ACLS, there needs to be formulated the system which can be supported by income from endowment, private grants, and private gifts. Third, like JSPS's grant-in-aid for 'Scientific Periodicals', it needs to bring in the principle of high competition in the allocation of KRF's existing 'Journal Publication Subsidy program. Fourth, besides the KRF's existing subsidy program for academic society, KRF needs to support academic society's educational program for student, teacher, and individual citizens in order to disseminate academic information and strengthen the scientific potential of Korea. Finally, it is necessary to formulate the system that the representatives of learned society take part in the academic policy-making body, screening committee, and selection process of KRF.

This study was made to get the cultural information for increasing yield with recently improved variety, investigating the effects of different transplanting date and seed size, the number of plant per hill on the growth, and the yield and yield components in rice. The results obtained were summaried as follows: 1. In larger seed, the percentage of germination was higher and the early growth was more vigorous. However, there appeared no effects of seed size in the later growing period. 2. When the young plants sown on April 26 were transplanted on 5th, 15th, 25th of June and 5th of July with 10-days interval, the heading date was promoted in earlier transplanted plots. The days to heading, however, was shortend. 3. In the case of the earlier transplanting in Tongil variety, the maximum number of tillers was increased, the percentage of effective tillers was decreased, and the rate of ripened grains was slightly higher. The yield was the highest in the transplanted plot of June 25. The next came the transplanted plots of 25th, 5th of June and 5th of July. In the early transplanted plot of Palkweong variety, heading was also promoted. The days required for heading were also proportionly shortend, the number of the effective tillers was smaller and the percentage of ripened grains also decreased. The productivity was the highest in transplanted plot of June 25. 4. When the number of plants per hill was increased, the heading date was promoted, the number of panicles was high and the number of grains per panicles was decreased. In the early transplanting of Tongil variety, the yields was the highest in 4-plants plot. When transplanted late, it was the highest in 6-plant plot. In Palkweong variety, there was general tendency of increasing of yield as the number of plants per hill increased. 5. The dwarf disease of Tongil variety and the stripe disease of Palkweong variety occurred much in case of the lesser number of plants per hill and the earlier transplanting.

We investigated the effect of aqueous extract of Ammomum xanthioides(AXAE) on immediate hypersensitivity. AXAE inhibited systemic anaphylaxis induced by compound 48/80 in mice. AXAE inhibited serum histamine levels induced by compound 48/80 in mice. Moreover, AXAE dose-dependently inhibited histamine release in peritoneal mast cells activated by compound 48/80. These results indicate that the AXAE may be benificial in the regulation of immediate type allergic reaction.

In this paper, a Four-wired antenna was designed and manufactured using Four-wires in order to perform EMI/EMC experiments. As compared with a TEM cell, the feature of the Four-wired antenna has simple installment with broadband balun, a Four-wired antenna, and loading resistances in an anechoic chamber. And the E-field polarization of antenna can be easily changed. Without the limitation of space, EMI/EMC experimental environment could be built within the anechoic chamber with the moderate cost. In S, C, and X-bands, the manufactured antenna was able to make an experiment on EMI/EMC with the DUT which has the quiet zone of the height, width, length equal to about 10 cm. 본 논문은 Four-wired 안테나를 이용하여 EMI/EMC 실험을 할 수 있는 안테나를 설계, 제작하였다. 일반 TEM-cell과 비교하여 이번 논문에서 설계, 제작하는 안테나의 특징은 무반향실에 broadband balun, Four-wired 안테나와 Loading resistances을 쉽게 설치하여, E-field polarization을 선택 할 수 있다는 점이다. 그리고 공간의 제약없이 기존의 무반향실을 이용하여 적은 비용으로 EMI/EMC 실험 환경을 구축할 수 있다. 제작된 안테나는 S, C 및 X-band에서 EMI/EMC 실험을 할 수 있는 가로, 세로, 높이 모두 약 10 cm 정도의 크기를 갖는 quiet zone을 얻을 수 있었다.

This study was conducted to assess the effects of noise exposure and psychosocial factor on blood pressure in manufacturing workers. The study subjects are 414 workers(243 males, 171 females) employed at the noisy department. The mean age of low exposed group(<85dB) was 34.65±9.53 years, and that of high exposed group(≥85dB) was 36.37±11.15 years. The difference in mean age was not significant. The mean and distribution of working duration, smoking status, drinking status were not significantly different between two groups. The mean systolic blood pressure of the low exposed group was 120.01±12.06 mmHg, and that of high exposed group was 126.27±13.84mmHg. The mean diastolic blood pressure of the low exposed and the high exposed group were 77.18±10.83 mmHg, and 83.46±11.22mmHg respectively. These differences of blood pressure were statistically significant(p<0.05). The workers in noisy department have significantly less work environmental satisfaction, higher job demand, and higher social support. The mean values of psychosocial distress were higher in the workers of the noisy department, but the difference was not statistically significant. This study was to speculate whether the work environmental satisfaction and social support modify the association between the noise exposure level and the blood pressure. The result showed that work environmental satisfaction could not modify the association between the blood pressure and the noise exposure. Social support at work did not modify the association. Furthermore, we evaluated the high job strain from a combination of ratio of the high job strain group for hypertension in diastolic blood pressure were statistically significant, but not in systolic blood pressure. Hierarchical multiple regression analysis was used to determine whither the independent variables contributed to explaining the blood pressure. After controlling for possible confounders, we found that the noise exposure level was a correlated of the diastolic blood pressure. But no association between the noise exposure level and the systolic blood pressure. No significant result was found for psychosocial factor.

김태환,정인용,김성호,김경중,방효창,류성렬,진수일 대한방사선 방어학회 1990 방사선방어학회지 Vol.15 No.2

원자력산업의 시설증대로 우라늄 오염의 가능성이 증가되고 있음에도 불구하고 종사자 및 국민에대한 안전대책 및 의료적 처치에 관한 연구가 매우 미흡한 실정에 있어 이에 대한 응급처치방안을 수립코자 우라늄을 투여한 후 제염제를 투여하여 관찰하였던 바 다음과 같은 결론을 얻었다. 1. 우라늄오염에 의한 체중변화에 미치는 제염제의 영향에 있어서 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol을 투여한 군에서는 우라늄단독투여군에 비해 체중이 현저하게 증가하였다. (P<0.05). 2. 모든 실험군은 우라늄오염에 의한 음수량과 배뇨량의 변화를 유의성 있게 호전시켰으며(P<0.05), 특히 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol을 투여한 군이 가장 높은 증가경향을 나타냈다(P<0.05). 3. 우라늄오염에 의한 BUN농도 변화에 미치는 제염제의 효과는 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군이 공히 우라늄단독투여군보다 BUN농도가 매우 감소되었다(P<0.01). 4. 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군은 우라늄오염에 의한 serum creatinine의 농도증가를 유의하게 감소시켰으나 (P<0.01), sodium bicarbonate와 생리적 식염수를 병행투여한 군은 다소 감소하는 경향으로 나타났다. 5. 우라늄오염에 의한 urine creatinine농도 변화에 미치는 제염제의 효과에 있어서 sodium bicarbonate와 생리적 식염수를 병행토여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군에서는 우라늄단독투여군에 비해 creatinine의 배설이 상당히 증가하였다(P<0.05). 6. 우라늄오염에 의한 신장의 소견에 있어 우라늄단독투여군은 근위곡세뇨관상피의 공포화 및 종창, microvilli와 brush border의 손실, 세뇨관 상피의 괴사가 관찰되었으며, 간장의 충혈, 중심성 괴사 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군에서는 우라늄단독투여군에 비해 높은 방호효과가 관찰되었으나 다른 실험군에서는 큰 효과가 없는 것으로 나타났다. 결론적으로 우라늄의 체내오염시에는 sodium bicarbonate와 생리적 식염수를 가능한 빨리 병행투여하거나 dithiothreitol을 체내오염후 30분이 지나서 투여하는 방법이 우라늄오염에 대한 제염에 매우 유효할 것으로 생각되며, 특히 우라늄에 의한 인체장해를 유의하게 경감시켜줄 것으로 사료되었다. Appreciable radiation exposures certainly were occurred m the reactor burn-up, the nuelear fall-out and the surroundings of nuclear installations with radioactive effluents. Therefore ,radioactive nuclides is not only potentially hazardous to workers of nuclear power plants and related industrials, but also the wokers who handle radioactive nuclides in biochemical research and nuclear medicine diagnostics. And in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little is established'medical procedures to decontaminate the victims of internal contamination of radioactive nuclides in korea. Accordingly, to achieve the basic data for protective roles and medical treatment of radiation injury, the present studies were can-id out to evaluate the decontamination of uranium by the chemical drugs. The results observed were summarized as follows : 1. The combined treatmet group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection were increased significantly in the change of body weight than uranyl nitrate-only group(P<0.005). 2. All the experimental groups were increased the fluid intake and urine volume on the uranyl nitrate-induced acute renal failure, but the combined treatment group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection have the higher increment of fluid intake and urine volume(P<0.05). 3. When sodium bicarbonate and saline was treated with uranyl nitrate injection simultaneously, and dithiothreitol was administered 30 minutes after uranyl nitrate injection, there was significantly reduced in BUN concentration (P<0.0l). 4. When dithiothreitol was administered 30 minutes after uranyl nitrate injection, there was reduced more significantly on the increment of serum creatinine concentration than that observed in uranyl nitrate-only group(P<O.Ol). but when the combined treatment of sodium bicarbonate and saline with uranyl nitrate simultaneously, there was still, albeit much less marked, decrease in serum creatinine concentration. 5. The sodium bicarbonate and saline was treated with uranyl nitrate simultaneously and dithiothreitol was administered at 30 minutes after uranyl nitrate were excreted markedly higher urine creatinine concentration than the uranyl nitrate-only group. 6. Uranyl nitrate has been used in experimental animals to produce hydropic degeneration and swelling of proximal tubules, disappearance of microvilli and brush border or necrosis in the kidney and centrilobular necrosis, congestion, and telangiectasia of the liver. When the sodium bicarbonate and saline was treated with uranyl nitrate simultaneously, and dithiothreitol was administered 30 minutes after uranyl nitrate, there was more marked the protective effect than uranyl nitrate-only group. Finally, if the sodium bicarbonate and saline may administered as quickly as possible each time that some risk for internal contamination with uranium, and dithiothreitol is administered 30 minutes after uranium contamination, there ameliorates the course of uranyl nitrate-induced acute renal failure,and this effect is assocciated with prevention of uranium (heavy metal) induced alterations in BUN. serum creatinine. urine creatinine. fluid intake, urine volume and body weight.
