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.

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.

A multipurpose Ultra High Vacuum chamber was designed and constructed in this laboratory. This enables us to be equipped with various analytical instruments such as Ar-ion gun LEED optics, Electron analyzer, and Quadrupole mass spectrometer etc. The 4-Grid LEED optics, a product of Omicron company in West Germany, was equipped with the UHV chamber and the LEED power supply was designed by this group. Turbo-C language figured out Auger spectra of the ad-species by means of the computer interface. The resolution of Auger electron spectrometer was measured with a constant primary electron beam energy. The results showed that the resolution was independent of the primary electron beam energy, but depends on the modulation voltage. Also, it was revealed that the resolution of 4-Grid optics was more improved than that of 3-Grid optics.

The purpose of seed coating is to make seedling mechanization possible by enlarging the seed size. The objective of this study was to determine the optimum of polymer and particulate matters for seed coating in perilla. There were significant differences of percent germination and germination speed in accordance with the coating polymer and the concentration. Among the coating polymer, germination of seeds using polyvinyl alcohol (PVA) was generally smooth, and followed by polyvinyl pyrrolidone (PVP), hydroxyethyl cellulose (HEC), and methyl cellulose (MC). The germination rate was also different according to the coating particulate matters. Generally, percentage germination and germination speed of seeds using the mixture of diatomaceous earth, talc and bentonite were higher and faster than using other coating materials, respectively. However, percentage germination using limestone was low, and percent germination of coated seeds with coating material showed the tendency of decreasing more than that of the seeds just added with coating particulate matters.

스칼라형 작용소의 스펙트럼으로 제한한 스펙트럼으로 제한한 스펙트럼 작용소의 특성화에 관하여 생각할 때, 그룹 ?^(its)에 필요조건을 첨가함으로써 유계선형작용소 S가 pseudo-hermitian 작용소가 된다. Reflexive Banach 공간상의 유계선형작용소 S가 pseudo-hermitian 작용소가 되기 위한 필요 충분한 조건은 f∈L1(R)가 ?∫Rf(t)?^(its)dt?? M?f?∞ 이다. We are concerned with the characterization problem for bounded spectral operators. We restrict the discussion to scalar type operators with real spectrum. The simplest criterion of this kind is for Helbert space. We give additional necessary conditions on the group ?^(its), which together with its uniform boundedness are both necessary and sufficient for S to be pseudo-hermitian operators. A bounded linear operator S on a reflexive. Banach space is pseudo-hermitian operators if and only if for every f in L1 (R), we have ?∫Rf(t)?^(its)dt?? M?f?∞ where the norm on the left is the operator norm, f is the Fourier transform of f and ???∞ is the sup norm.

We report a case of tuberous sclerosis accompying the typical stigmata in a 18-year-old women who had undergone right nephrectomy. 40 to 80 per cent of tuberous sclerosis patients have renal angiomyolipoma. When angiomyolipoma is associated with tuberous sclerosis, the renal tumors usually are bilateral, muliple, samll and asymptomatic. Currently, it should be possible to make the diagnosis of angiomyoliporna in most cases on the basis of the combined imaging characteristics of CT and ultrasongraphy. Lesions associated with tuberous sclerosis require surgical intervention only when they become symptomatic or enlarge silently.

Transrectal ultrasonography can provide a precise image of the prostate, seminal vesicles and adjacent structure. It can play a valuable role in the diagnosis of prostatic diseases, particulary in the detection, staging and monitoring after treatment of prostatic cancer. Transrectal ultrasonography was taken in 51 patients with prostatism (34 cases of benign prostatic hyperplasia and 17 cases of prostatic cancer), and the results were compared with the pathologic results of prostatic tissue obtained by digitally guided biopsy or surgical specimens. The results were as follows: 1. The sensitivity, specificity, positive predictive value, and dectation rate of trasrectal ultrasonography for prostatic cancer were 88.2%, 97.1%, 93.8%, and 29.4%, and in digital rectal examination, sensitivity, specificity, positive predictive value and dectation rate were 64.7%, 97.1%, 91.7% and 21.6%, respectively. 2. Echogenecity of prostatic ultrasonography in prostatic cancer were hypoechoic in 12 cases(70.5%), hyperchoic in 3 cases(17.7%) and isoechoic in 2 cases(11.8%), and in benign prostatic hyperplasia, isoechoic in 33 cases(97.1%) and hyperechoic in 1 case(2.9%).

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.

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.
