최점수,김재형 인제대학교 1984 仁濟醫學 Vol.5 No.4

The purpose of this study which based on the experimental measurement about the energy loss of internal conversion electrons of 411.8 keV, and 1087.4 keV(Au-198 internal conversion K-, L-, and M-lines) is to measure the slopping power of the foils. The initial and the final momentum of the electrons were determined, and from these the energy loss of foils was calculated with the measuring of the peak's shift degree. The most probable energy loss of the electrons as a function of the thickness of the foils is shown on the graph, as the result of it, the experimental data of energy loss as a function of thickness is in good agreement with the theoretical one. For the 1987.4 keV(K-line), the result is not so good because the effect of the Bremsstrahlung is a little more than the one of scattering.

In order to find out the influence of shading degree on the growth, pod setting, protein contents, RuBPCase activity, photosynthesis and yield in soybean plants, two soybean varieties, Hill and Etaka were cultivated under the 0%(full sun light), 20%, 65% and 90% shading conditions. Protein contents, RuBPCase activity and photosynthesis of leaves in Hill were decreased linearly with the higher shading, but those in Etaka were increased up to 20% shading, and then decreased more rapidly than Hill when the shading was above 65%. Pod sets were decreased with the higher shading degree, and those of the degree were severe in upper nodes. The stem heights were increased in accordance with the shading up to 65%, but stem diameter and No. of branches were decreased linearly with the higher shading degree. The yield of Hill was decreased linearly with the higher shading degree, but that of Etaka were increased up to 20% shading, and decreased inure severely than Hill when the shading was above 65%. From the above results : Etaka is more suitable than Hill to weak shading which occurred in the case of intercropping, companion cropping and alternating cropping, and the shading degree must not go over above 20%.

최근 현대인의 실내거주시간이 일상생활시간의 80% 이상을 차지할 정도로 크게 증가하면서 보건·위생학적 측면에서 실내공기질은 매우 중요한 관심사로 등장하게 되었다. 본 연구는 1994년 8월의 여름철과 1994년 12월 ∼1995년 1월의 겨울철에 대구를 중심으로 가정집, 사무실, 식당과 같은 3가지 유형의 일반주거환경 중 실내·외 공기를 대상으로 실행되었다. 측정항목으로는 RSP, CO, CO₂, NO₂등의 주요 기준성 오염물질과 Bioaerosol을 선정하였다. 본 연구의 결과, 각 성분대상물질의 실내·외 농도는 실내거주환경 및 여름과 겨울, 두 계절에 따라 영향을 받는 것으로 나타났으며 실내·외 농도비교에서 RSP, CO, CO₂의 실내농도는 대부분의 지역에서 실외에 비하여 높은 농도를 나타냈다. 각 실내거주환경에 따른 실내·외의 농도는 가정, 사무실에 비하여 식당에서 상대적으로 높은 농도를 나타냈으며 실내·외 농도비 또한 식당에서 상대적으로 큰 값을 나타냈다. 여름과 겨울의 두 계절에 따른 RSP, CO, CO₂의 실내·외 농도는 여름철에 비하여 겨울철에 더욱 높은 농도를 나타냈으나 Bioaerosol의 실내·외 colony/plate는 여름철에 더욱 높은 수치를 나타냈다. The study was carried out to investigate the concentrations of indoor air pollutants such as respirable suspended particulate (RSP), carbon monoxide (CO), carbon dioxide (CO₂), nitrogen dioxide (NO₂) and bioaerosol at homes, offices and restaurants in Taegu city. Indoor and outdoor concentrations of these pollutants were observed simultaneously from August 1994 for summer to January 1995 for winter. The results were summarized as follows : 1. Both in summer and in winter, the indoor concentrations of RSP, CO, and CO₂; were higher than the outdoor concentrations, the indoor concentrations of major air pollutants (RSP, CO, CO₂, NO₂) in restaurants were higher than those in homes and offices. 2. The indoor and outdoor concentrations of RSP, CO, and CO₂; in winter were significantly higher than those in summer, on the other hand. The CFU/plate of bioaerosol in winter was lower than that in summer. These results suggested that indoor levels of air pollutants were affected by various indoor characteristics such as smoking, cooking, ventilation rate, winter heating systems, and behavioral activity of occupants.

국내외로부터 수집한 고추 유전자원을 포장에 재배하여 종자를 증식하는 동시에 주요 특성을 조사하였다. 헝가리에서 도입하여 1992년도에 평가한 계통들은 Hungarian Wax 혹은 Bell형으로서 바이러스에 심하게 걸려 우리포장환경에 잘 적응하지 못하였다. 1994년도에 평가한 계통들 중 브라질에서 풋마름병 저항성으로 도입한 KC350과 KC351은 직립성이며 바이러스에 강한 편이어서 매우 유망한 유전자원으로 사료되었다. 중국에서 도입한 KC376는 바이러스에 강한 편이며 대과를 착생하여 유망하게 보였다. 태국에서 도입된 계통들은 안동대에서 특성을 평가기록하였다. Accessions of pepper germplasm were planted in the field and their characteristics were recorded. Lines introduced from Hungary were very susceptible to virus diseases and as a result poor in adaptability in domestic field condition. KC350 and KC351 which were introduced from Brazil were growing errectly and tolerant to both bacterial spot and virus diseases. KC376, an introduction from China, was bearing large fruits with tolerance to virus. Introductions from Thailand were grown and evaluated in Andong Universiy, and major characters of them were recorded.

In January 1983, the writer visited a few universites in Japan to survey the recent trend of studies in cultural and social Sciences. At that time what I researched is as follows; In Japan, many a learned society has been organized and the research activities were very lively. Mass publication of scientific periodicals and prompt translation of foreign writings showed the maturity of scientific atmosphere. It true that their study of literature has been performed on the basis of positivism since 1930'. But now Structuralism which consider's literary works as one organic unity of parts became the main basis of literary studies. And, Learned Society of Educational Law has been organized in Japan. In consequence, the level of researches in educational law could be remarkably high. So, it is necessary for us to study the law of education. For, to make it better, we must know not only the universal principles of education but also specific ones derived from the peculiar characteristics of Korean education. At the same time, in Japan, Department of the Law of Industrial Administration was established in 14 universities including Japan University. And with the help of it, companies could improve the efficiency in dealing with judicial affairs related with industrial administration. So, to be a winner in the international trade competition, it is also required for us to study the judicial affairs of industrial administration.

Ultrastructural Differences in Mixed Infections of Six Turnip mosaic virus and One Ribgrass mosaic virus Isolates in Crucifers

Kim, Jeong-Soo,Cho, Jeom-Deog,Park, Hong-Soo,Kim, Kook-Hyung,Kim, Kyung-Soo The Korean Society of Plant Pathology 2003 Plant Pathology Journal Vol.19 No.2

Six isolates of Turnip mosaic Potyvirus (TuMV) namely, TuMV-CA7 from oriental cabbage, TuMV-TU and TuMV-TU2 from turnip, TuMV-RA from rape, TUMV-ST from stock, and TuMV-R9 from radish, and Ribgrass mosaic Tobamovirus (RMV-FG22) from oriental cabbage were isolated. Three kinds of characteristics of the six TuMV isolates were sorted by bioassay: TuMV-CA7 and TuMV-TU isolates infected mostly oriental cabbages; TuMV-ST, TuMV-TU2, and TuMV-R9 infected radishes; and TuMV-RA infected both oriental cabbages and radishes. Mixed infections of crucifers were RMV-FG22+TuMV-CA7, RMV-FG22+TuMV-TU, RMV-FG22+TuMV-RA, RMV-FG22+TuMV-ST, RMV-FG22 +TuMV-TU2 and RMV-FG22+TuMV-R9. Crops used were 'Tambok' cultivar resistant to TuMV, 'SSD63' susceptible inbred line of oriental cabbage, pure line of leaf mustard and 'Daeburyungyeorum' cultivar of radish. New specific ultrastructures of nonagon-like ring (NLR) and spiral aggregates (SA) by mixed infection with TuMV and RMV were formed in cells of crucifer plants. The NLR was made by a TuMV surrounded loosely by nine RMV particles, and the SA was formed spirally by full mixed of two virus particles. The SA had some NLR in its center, which was observed from cross sectioned SA. Host plants with specific ultrastructures expressed synergistic symptoms. Specific ultrastructures of NLR and SA were formed in combinations of RMV-FG22 and in TuMV-CA7, TuMV-TU, or TuMV-RA that could infect oriental cabbages. How-ever, no specific ultrastructures and mixing of the two virions in the same cell were observed in combinations of RMV-FG22, and TuMV-57, TuMV-TU2, or TuMV-R9 isolates haying virulence in radishes.

Symptom Variances in Mixed Infections of Six Turnip mosaic virus and One Ribgrass mosaic vims Isolates in Crucifers

Kim, Jeong-Soo,Cho, Jeom-Deog,Park, Hong-Soo,Kim, Kook-Hyung,Kim, Kyung-Soo The Korean Society of Plant Pathology 2003 Plant Pathology Journal Vol.19 No.2

Turnip mosaic Potyvirus (TuMV) and Ribgrass mosaic Tobamovirus (RMV) are major viruses infecting crucifer crops in Korea. RMV-FG22 was isolated from oriental cabbage. TuMV isolates were TuMV-CA7 from oriental cabbage, TuMV-TU and TuMV-TU2 from turnip, TuMV-RA from rape, TuMV-ST from stock, and TuMV-R9 from radish. The six isolates of TuMV were classified by symptom expression in inbred lines of crucifers. TuMV-CA7 and TuMV-TU isolates infected mostly oriental cabbages; TuMV-ST, TuMV-TU2, and TuMV-R9 infected radishes; and TuMV-RA infected both oriental cabbages and radishes. Crops used in six combinations of mixed infections were 'Tambok' cultivar resistant to TuMV,'SSD63' susceptible inbred line of oriental cabbage, pure line of leaf mustard, and‘Daeburyungyeorum’cultivar of radish. External symptoms in 'Tambok' and radish by each of the six single infections of TuMV showed similar results by bioassay. Synergistic response of necrotic death occurred within 1 week after inoculation in all combinations mixed with TuMV and RMV-FG22 on leaf mustard. In oriental cabbage 'SSD63' , synergism of necrosis occurred in four TuMV isolates, but not in TuMV-ST and TuMV-R9. In oriental cabbage 'Tambok' , synergism was expressed only in two combinations of RMV-FG22+TuMV-CA7 and RMV-FG22+TuV-TU, but other combinations had the same symptoms produced by RM-FG22. In radish‘Daeburyungyeorum’, only mild mosaic symptoms were induced by combinations of RMV-FG22+TuMV-CA7, RMV-FG22+TuMV-TU, RMV-FG22+TuMV-RA, and RMV-FG22+TuMV-R9. Mosaic and severe mosaic were induced in combinations of RMV-FG22 +TuMV-TU2 and RMV-FG22+TuMV-ST, respectively.

Ultrastructural Characteristics of Necrosis and Stunt Disease in Red Pepper by the Mixed Infections of Tobacco mosaic virus-U1 or Pepper mild mottle virus and Pepper mottle virus

Kim, Dae-Hyun,Cho, Jeom-Deog,Kim, Jae-Hyun,Kim, Jenog-Soo,Cho, Eui-Kyoo The Korean Society of Plant Pathology 2005 Plant Pathology Journal Vol.21 No.3

In single infection of Tobacco mosaic virus-U1 (TMV­U1) or Pepper mild mottle virus (PMMoV), mosaic symptoms were produced on the chili pepper cultivars of 'Cheongyang' and 'Wangshilgun'. However, in cultivars of 'Manitta' and 'Bugang', no symptoms were occurred. In single infection of Pepper mottle virus (PepMoV), symptoms of mottle and malformation were produced on the tested cultivars of 'Manitta', 'Bugang', 'Cheongyang', and 'Wangshilgun'. In the cultivars of 'Cheongyang' and 'Wangshilgun', synergistic symptoms of stunt and lethal death were induced by mixed infections in the two combinations of TMV-U1 + PepMoV and PMMoV+PepMoV. However, in cultivars of 'Manitta' and 'Bugang', synergistic symptoms were not noted, but mottling which was milder than that of single infection was produced. Cells infected singly with TMV-U1 and PMMoV in the cultivars of 'Cheongyang' and 'Wangshilgun', respectively, had the typical ultra-structures of tobamovirus as the stacked-band structure and multiple spiral aggregate (SA). In the cells and tissues infected with PepMoV on the cultivars of 'Cheongyang', 'Wangshilgun', 'Manitta' and 'Bugang', the potyvirus inclusions of pinwheels, scrolls, lamminated aggregates and amorphous inclusion were observed. In the cells infected mixedly with combinations of TMV­U1+PepMoV and PMMoV+PepMoV, the virus particles and inclusions of the two different viruses were found simultaneously in the same cytoplasm. The amounts of virus particles in mixed infections were more abundant than in single infection. The angled-layer aggregates (ALA) were observed only in the cells infected with both TMV-U1 and PepMoV.
