HONG, Soon-Woo, & KIM, Chong-Chin: A study of virus disease on chinese date tree (I). On the external and the internal morphogical characteristics of disease inrected plants. Kor. Jour. Bot. 3 (1). 32-38. 1960 Since the peeuliar virus disease of chinese date tree (Zizyphus jujuba Mill. var. inermis Rehd.) has been noted in South Korea around 1950, 70% to 80% of the economically important trees have been either completely destroyed or infected with the virus, severe damage has been noted, particularly, across the area ranged from middle east to the middle part of Korea, including Seoul area. Yoon,-Koock-Byung in 1958 first reported the disease and described it might be caused by a kind of yellows. But he did not conform in his paper that the disease is pecisely caused by yellows virus. The authors, hereby intend to identify the true cause of the disease of the chinese date tree by studying the external symptoms of the disease and the internal morphological characteristics of the diseaset plant which shows various abnormalities in contrast to the healthy checks. In view of fact that the leaves of the infected plants become yellowish in color similar to the peach yellows, aster yellows, it is likely to be identifiable as the common yellows. Furthermore, the abnormal characteristics observed by the authors are as follow: The floral organs such as petals, sepald, stamens, and pistil turn into vegetative leaves, the leaves on heavily infected plant appear as small sized one and also showing as a common witch`s broom like symptom. There are also an occuring of numerous advantitious shoots developed from both of stems and roots. The amount of photosynthetc starch grains increses iIn parenchymatous cells, necrosis takes place in mesophyll, Partlcularly, Palisade Parenchyma in the leaves of infected plants are distinguished in contrast to the healthy checks. From the symptoms and the present experiments described above, the authors are belived that the disease of chinese date tree is not caused by the yellows. It appears the disease is rather similar to the symptoms of sandal spike virus which was noted in India early in this centry. But the host plant of sandal disease, Santalum album L. and the insect vector, Jassus indicus Wal., have never been reported in Korean flora and the founa. The temperature and the other environmental factors is auite different Korea ard India. Thus the authors believe that the peculiar disease must be an endemic new virus origin in Korea and must be called as shoot cluster disease of chinese date tree.

日本語의 前提文 分析

鄭炳南,權順禮 진주여자전문대학 1990 論文集 Vol.12 No.-

Presupposition in the Japanese linguistics can be classified into a process derived by the subordinate clause of syntactic structure and that by structure of lexical meaning. So, I can analyze this study as the developing process of the presupposition theory. Firstly, discussing the presupposition by syntactic structure, we can find that the same structures as relative clause, adverbal clause and cleft sentence belong to this kind. Also these presupposition sentences are in general derived from the subordinate clause of each syntactic structure. Secondly, discussing the presupposition by lexical meaning, the presupposition is derived by the semantic features of noun, adverb, auxiliary and verb. The most important factor is verb which is divided into factive and implicit verbs. Consequently, this study reveals that presupposition should be first analyzed by semantic level and then structure level, too. Tense and aspect also can be examined in the semantic level.

급성 간손상의 실험동물 피부조직에 있어서 Oxygen Free Radical의 대사효소 활성 변동

채순님,전태원,윤종국 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1999 Journal of biomedical laboratory sciences Vol.5 No.1

실험동물에 있어서 CCl₄에 의한 급성 간손상시 피부조직의 oxygen free radical 대사효소 활성 변동을 검토하기 위해 흰쥐에 CCl₄와 olive oil의 동량 혼합액을 체중 100g당 0.1ml씩 복강으로 투여하여 처치하였다. CCl₄투여로 인한 혈청 alanine aminotransferase 및 xanthine oxidase (XO) 활성은 현저히 증가되었으며 체중당 간무게(%) 및 간조직의 malondialdehyde 함량 역시 유의하게 증가되었다. 그리고 병리조직 검사에서도 CCl₄투여군에서 간조직의 괴사성 병변이 관찰되었다. 따라서 CCl₄를 투여한 실험동물이 급성 간손상 모델로 확인되었다. 이와 같은 간손상 실험동물의 피부조직 중 oxygen free radical의 생성효소인 XO 활성은 대조군과 별다른 차이를 볼 수 없었으나 oxgen free radical의 scavenging 효소인 superoxide dismutase, glutathione peroxidase 및 catalase 활성은 대조군에 비하여 유의하게 감소되었다. 또한 세포화학적 검사에서 cerrous perhydroxide 과립이 간손상 실험동물의 피부조직에서 많이 나타났다. 이상 실험결과는 CCl₄에 의한 급성 간손상 유도 실험동물의 피부조직에 H₂O₂의 축적이 나타나는 현상을 시사해주고 있다. To evaluate an effect of liver damage on the dermal oxygen free radical metabolizing enzyme activities, the CCl₄(0.1ml/100g body wt., 50% CCl₄in olive oil) was intraperitoneally given to the rats every other day for 2 weeks. Based on the histopathological findings, liver weight (%), serum alanine aminotransferase, xanthine oxidase activities and hepatic lipid peroxide contents, the animals were induced severe liver damage. In the present liver damaged animal, all the activities of dermal scavenging enzymes such as superoxide dismutase, catalase and glutathione peroxidase were significantly decreased compared with contral. And under the cytochemical electron microscopy the more coarse granules of cerrous perhydroxide were found compared with the control. In conclusion, the CCl₄-induced liver danage may influence upon the activities of some dermal oxygen free radical scavenging enzymes.

Traumatic renal injuries, with other multiple organ system injuries, are gradually increased due to various causes such as increased traffic accidents, industrial works, sports and violence, and their degrees of injuries are varieable. We reviewed 207 traumatic renal injuries at the Department of Urology, Chungnam National University Hospital during the period from January 1985, to August 1991, with the literatures as follows. 1. Most of the cases(152 cases, 68.6%) were distributed in 3rd to 5th decade, and more prevalent in male(male to female ratio was 4.3:1). 2. Main causes of renal injuries were traffic accident(118 cases, 57.0%), fall-down(48 cases, 23.2%), assault (33 cases, 15.9%), and stab (8 cases, 3.9%). And vulnerable age group to trauma according to causes were 3rd decade in traffic accident, 5th decade in fall-down, 3rd decade in assault, and 3rd and 4th decade in stab. 3. Incidences of associated injuries according to causes were 61.0%(72 cases) in traffic accident, 39.6%(19 cases) in fall-down, 37.5%(3 cases) in stab and 36.4 %(12 cases) in assault. But multiplicities in combined injured patients(106 cases) were 2.4 in fall-down, 2.1 in traffic accident, 2.0 in assault and stab repectively in its frequency. 4. Preexisting renal diseases were hydronephrosis(4 cases), horse-shoe kidney(2 cases), crossed ectopic kidney(1 case), renal cell carcinoma(1 case), staghorn stone(1 case) and ureteral stone(1 case). 5. Of 207 renal injuries, minor injuries were contusion(148 cases), superficial cortical laceration(7 cases), subcapsular hematoma(2 cases), and major injuries were deep corticomedullary laceration(21 cases), shattered kidney(14 cases), pelvis tearing(8 cases) and vascular injury(7 cases). 6. Hematuria was seen in all injured cases, but gross hematuria in minor injury was seen in 41.2%(49 cases), and, in major injury, was seen in 74.0%(37 cases). 7. Diagnostic procedures in minor injury were DIP(142 cases), DIP and CT(9 cases), CT only(2 cases), and DIP and renal angiography(2 cases), but in major injury, were DIP only(19 cases), DIP and CT(19 cases), DIP and renal angiography(7 cases), CT only(2 cases), and DIP, CT and renal angiography(3 cases). 8. Types of management for renal injury in minor injury were conservative(154 cases), primary repair(3 cases), and in major injury, primary repair(19 cases), nephrectomy(18 cases) and conservative(13 cases). 9. Complications were developed in 10 cases(5.0%) of 201 treated cases (with exception for 6 cases who were dead with other causes of death in renal contusion with multiple injuries) such as bleeding(5 cases), retroperitoneal urinoma(2 cases), infection(1 cases), hypertension due to AV fistular(1 case), and uremia(l case) in whom received aorto-renal bypass procedure.

朴映淳,朴鍾君,金賢玉,金鍾鎬,李東燁,金完柱 圓光大學校 1988 論文集 Vol.22 No.2

培養鷄胚筋細胸 分化에 미치는 促進物質의 영향을 알아보고자 2가양이온 (Ca2+, Mg2+) 胸胚抽出物 (EE), polyethylene glycol (PEG), 再生中인 도마뱀 (Lacertilia)꼬리 추출물 (BE)을 처리하여 細胸融合指數를 비교 조사하였다. 정상배양시의 細胸融合指數는 배양시작 70 시간에 최대에 달했으며 더이상 증가하지 않았고, Ca2+와 Mg2+ 처리할 경우에는 농도가 증가할수록 細胸融合指數는 저하되고, 근세포의 굵기도 정상세포보다 가늘고 핵이 모여있었다. Polyethylene Glycol (PEG)와 Blastemata Extract (BE) 처리군에서는 대조구와 큰 차이가 없는 것으로 나타났다. 鷄胚抽出物 (EE) 을 筋細胞分化에 필수적이나 과량으로 添加시에는 細胞融合은 억제되고 세포수는 증가되는것으로 나타났다. To study the effects of promoting factors on the differentiation of muscle cells, chick embryonic myoblasts were cultured with divalent cations (Ca2+, Mg2+) Chick embryo extract (EE), Polyethylene Glycol (PEG) and Blastema extract of Lacertilia (BE). Fusion index and Growth ratio were measured at various culture time. The fusion index of normal myoblast culture was reached maximum at 70 hours and the divalent cations (Ca2+, Mg2+) treated groups were decreased at higher concentration. The cellular formation of myoblasts treated with divalent cations was thiner and more aggregated between nuclei than that of normal myoblasts calture was. When polyethylene glycol (PEG) and Blastema extract of Lacertilia (BE) were treated to the myoblasts, tha fusion indices were similar to the control. Embryo Extract (EE) was seemed to be necessary for the fusion of chick embryonic myoblasts in culture, however, when excess of EE was added the fusion index was decreased and the number of cells was increased.

浸漬方法에 依한 오이지맛과 Vitamin C에 미치는 影響

李鍾順 聖心女子大學校 1975 論文集 Vol.6 No.-

① 10%食鹽水로 浸漬한 오이지의 浸鹽濃度는 約 5%이며 三伏中에도 浸漬後 20 日까지 그 硬度를 維持한다. ② 15%食鹽水로 浸漬한 오이지의 浸鹽濃度는 約 7.3%이며 浸漬後 約 1個月까지 硬度가 維持되어 貯藏性이 强한 浸漬法이다. ③ 20%食鹽水로 浸漬한 오이지의 浸鹽濃度는 約 10%이며 貯藏性이 가장 强한 浸漬法이기는 하나, 너무 짜서 不適하다. ④ 끓는 食鹽水로 浸漬한 오이지와 Dry salting 으로 浸漬한 오이지는 모두 오이內部의 水分이 急激히 溶出되어 쭈그러지고, Texture 도 오득오득하다. 貯藏性과 熟成度는 冷食鹽水로 浸漬한 製品과 差가 없다. ⑤ 오이지를 浸漬할 때 마늘을 저며 넣어 醱酵시키면 熱成適期에 酸化型 V·C含量만은 생오이보다 上昇된다. ⑥ 오이지를 浸漬할때 파를 添加하면 食鹽만으로 浸漬한 오이지보다 도리어 Total Vitamin C 含量이 減少된다. 그러나 香辛料로 因하여 오이지맛(냄새)에 미치는 影響은 없다.

박종윤,이순보,부진효,신익조 성균관대학교 기초과학연구소 1990 論文集 Vol.41 No.1

By using theoretical model suggested by H. Hartwig et al., performance of sputter ion pump (SIP) was calculated and a SIP was constructed. Measurement of pumping speed of the SIP has been performed with the differential pumping method. The pumping speed for N_2 gas is 48 l/s, and for Ar gas is 20 l/s. These results agree with the theoreticaly expected values.

Cs이 흡착된 Si(111)7×7표면에 대한 RHEED연구

박종윤,이순보,이경원,안기석,강건아 성균관대학교 1991 論文集 Vol.42 No.1

Cesium-adsorbed surface structures on Si(111)7×7 were investigated at room and high temperatures(200∼700℃) by RHEED. The RHEED patterns of Si(111) 7×7 was changed to the modified 7×7 and the 1×1 patterns with increasing the deposition times of Cs at RT. It was observed that the structure of the Cs-adsorbed Si (111) 7×7 surface at saturation coverage is the 1×1 structure at RT. The ◁그림삽입▷(원문을 참조하세요) 1 and 1×1 structures appeared successively at the adsorption temperature of 300℃, 350∼400℃ and 450℃, respectively. After subsequent heating of 1×1 surface above 550℃ and of ◁그림삽입▷(원문을 참조하세요) surface above 600℃, each RHEED pattern gradually returned to the original Si(111)7×7 pattern. 상온 및 200∼700℃의 Si(111)7×7 표면에 Cs(Cesium)을 증착하였을 때 표면격자구조의 변화를 RHEED로 관측하였다. Cs 증착시 Si(111)7×7 기판의 온도가 상온인 경우, 포화 덮임률에 도달했다고 추정되는 일정 증착시간 전에는 원래의 깨끗한 Si(111)7×7 패턴과 거의 유사한 변형된(modified) Si(111)7×7-Cs 패턴이 관측되었다. 그후 포화 덮임률에서는 1×1패턴이 관측되고 증착량을 증가시켜도 패턴의 변화는 관측되지 않았다. 이 구조를 다시 annealing시키면 약 550℃부터 서서히 원래의 7×7구조로 되돌아가기 시작한다. Si(111)7×7기판의 온도를 220∼700℃로 유지하면서 Cs을 증착시킨 경우에 약 250℃까지는 상온에서와 비슷한 변형된(modified) 7×7이 관측되고 약 300℃에서는 ◁그림삽입▷(원문을 참조하세요) 350∼400℃ 정도에서는 ◁그림삽입▷(원문을 참조하세요)과 3×1이 겹쳐셔 관측되었다. 그리고 450℃ 이상에서는 1×1구조가 관측되었다. 이때 약 300℃에서 형성된 ◁그림삽입▷(원문을 참조하세요) 350℃에서 형성된 ◁그림삽입▷(원문을 참조하세요) 3+3×1 구조는 약 500℃ 정도까지 다시 annealing함에 따라 다리 1×1구조로 상전이가 일어난후, 약 600℃부터 원래의 7×7의 초격자점들이 나타나기 시작했다. 이들 결과로부터 Si(111)7×7 표면에 Cs을 증착하는 경우에는 일정한 포화 덮임률(saturation coverage)이 있는 것으로 추정되고, 이 덮임률에서 관측된 고온에서의 상전이는 증착량(증착시간)에는 무관하고 온도에만 의존함을 알 수 있었다. 또한 1×1 구조와 ◁그림삽입▷(원문을 참조하세요) 구조에 대하여 Cs의 탈착은 각각 약 550℃와 600℃에서 일어나기 시작하여 700℃에서 완전히 탈착됨을 알 수 있었다.
