        거골 경부 골절의 치료

        조용만,이영기,리건영,이천동 대한골절학회 1996 대한골절학회지 Vol.9 No.4

        The talus has some important anatomic features. Approximately 60% of its surface is cartilage and The talus often has problems with circulation. Talar neck fracture have a high association with ostonecosis and osteoarthritis. Authors have analysed l6 cases of the talar neck fractures treated at Lee-Rha General Hospital from January l990 to December l995 with minimal I year follow up. The results were as follows; 1. In thr l6 cases, there were l4 males and 2 females. the age between 20 and 40 years old was 10 cases(63%). 2. The most common cause of injury was traffic accident(63%), with sudden hyperextension as its mechanism. 3. associated injuries were 4 malleolar fracutres, 3 calcaneous fractures, 3 spine fractures, 3 tiviofibular fractures and 2 femur fractures. 4. According to the Hawkins classification: 3 cases in type I, 4 cases in type I, 5 cases in type l. 4 case in type N fractures were observed. 5. The method of treatment, all 3cases of Hawkins type I fractures were treated by closed reduction and cast immobilization, 3 cases of Hawkins type l and I case of Hawtins type III fracture were treated by closed reduction and internal fixation, other 9 cases were treated by open reduction and internal fixation. 6. Excellent results were observed in 8 cases good in 5 cases, fair in 2 cases . poor in l case with the Hawkins' therapeutic criteria. 7. Complications was observed 3 avascular necrosis, 2 post-traumatic arthritis, 2 ankle stiffness and l skin necrosis. From the above results, authors believe that early anatomical reduction k internal fixation is impotent to get a satisfactory result in de treatment of talar neck fracture.

        조용만,이영기,강흥식,리건영,이천동,오상수 대한골절학회 1997 대한골절학회지 Vol.10 No.1

        The authors surveyed the clinical study of 17cases of scaphoid fractures from March 1989 to September 1994 with minimal I year follow up at Department of Orthopedic Surgery, Lee-Rha general Hospital. The following conclusions were obtained through clinical survey. l. Of all l 7 cases, they were l3 males and 4 females; Among the 13 males, 10 cases were aged between 20 and 39 years. forming 56.8% of all. 2. All 17 cases were treated by open reduction. Unions were obtained at average l l.5 weeks in 7 cases treated with Herbert screw fixation and l 2 weeks in l 0 cases treated with K-wire fixation. 3. Two of ten K-wire treated cases resulted in delayed union, one of seven Herbert screw treated cases resulted in delayed union. 4. Unions were obtained at average 20 weeks in 3 cases of delayed union. We concluded that open reduction and K-wire fixation were recomanded for the compatible treatment method of displaced waist fracture of scaphoid.

      • 시스템 成果的 次元에서의 DSS 機能에 관한 硏究

        李東萬,鄭忠泳 慶北大學校 1982 論文集 Vol.33 No.-

        In this paper, we'll argue the foundations of Decision Support Systems(DSS) at system performance dimension. Because its concept has not been established yet, the development process is examined in order to establish its concept, and then its definition would be able to be made. It was supposed that DSS is ideologically different from MIS in the intended object sphere of study, so we'll study its sphere and the differences between DSS and MIS, and try to make a model of DSS. DSS is studied in terms of data processing and of information value with a view to examining its fumctions and to examining how it plays a role in system improvement. Then a case-analysis in undertaking on performance improvement of data processing to make its function clrear. Inevitably, DSS concept has to be got influential along with the development of information techniques. So more continuous researches are needed on this subject.

        경골어류 카라신과 glow-light tetra의 난자형성과정

        이규재,장병수,등영건,김동희 韓國電子顯微鏡學會 2008 Applied microscopy Vol.38 No.4

        조기어강 (Actinopterygii), 카라신목 (Characiformes), 카라신과(Characidae)에 속하는 담수산 경골어류에 속하는 Glow-light tetra (Hemigrammus erythrozonus)의 난자형성과정을 다른 어류와의 차이점을 확인하기 위하여 광학현미경으로 관찰한 결과 난원세포의 세포질은 호염기성이었고 핵 내에 다수의 이형염색질들이 분포하고 있었다. 제1난모세포의 경우 난황포가 단지 난세포 가장자리에만 배열되어 있었고 난막의 형성은 관찰되지 않았다. 제2난모세포에서는 난막이 형성되었고 제1난모세포에 비해서 난황포가 점점 핵 쪽으로 증식된 경향을 보였다. 발생이 진행됨에 따라서 호염기성 물질들은 점점 감소하는 경향을 보였고 후에 난막 주위에만 국한적으로 분포하였으며, 난막의 두께와 난자의 크기는 점점 증가되었다. 이상과 같이 glow-light tetra의 난자형성과정은 난세포의 크기 증가, 난황낭의 축적, 염기성 물질의 감소, 난막발달 및 두께의 증가로 요약될 수 있으며 일반적인 다른 과의 담수경골어류와 큰 차이는 없는 것으로 확인되었다. 본 연구는 광학현미경상의 조직학적 결과이므로 앞으로 정확한 난자형성과정을 단계적으로 확인하기 위한 투과전자현미경을 이용한 미세구조적 연구가 필요하다. Glow-light tetra, Hemigrammus erythrozonus is a teleost belonging to Characidae. The natural habitate of this fish is the wild in the Essequibo river, Guyana and South America. The oogenesis of glow-light tetra was investigated by light microscopy to compare with those of other families. A pair of ovary was located between swim bladder and intestines. The ovary was of white color and ellipsoidal shape with the major axis 11 mm and the minor axis 4 mm. Cytoplasm of oogonia was basophilic and many nucleoli were located at inside of nuclear membrane. In primary oocytes, yolk vesicles were distributed only in the marginal area and egg envelope was not formed on the outside of an egg. In secondary oocytes, the egg envelope was formed and yolk vesicles in the cytoplasm were increased than the earlier stage. The amount of basophilic substance was decreased. In case of matured egg, thickness of egg envelope and size of egg were increased, basophilic substance was distributed in only around the egg envelope. The yolk vesicles were changed to yolk mass in accordance with development. In conclusion, the oogenesis of glow-light tetra, Hemigrammus erythrozonus was characterized by the increase in cell size, the formation and accumulation of yolk, and the decrease of basophilia a in the cytoplasm. The oogenesis of glowlight tetra seems to share common patterns in Characidae, teleost and have a similar pattern with other teleost.

        전신적인 피부병변으로 발현한 모세포성 NK세포 림프종 1예

        이근욱,윤탁,김동완,김태유,허대석,박영주,김노경 대한내과학회 2004 대한내과학회지 Vol.66 No.4

        저자들은 다른 장기의 침범 없이 전신적인 피부 병변만으로 발현한 모세포성 NK세포 림프종 1예를 국내에서 처음으로 경험하였기에 이를 문헌고찰과 함께 보고하는 바이다. Reports of blastic natural killer (NK)-cell lymphoma are rare. In previous reports, primary cutaneous blastic NK-cell lymphomas were even rarer. In asian patients, most CD56+ lymphomas are classified as nasal type extranodal NK/T-cell lymphoma and mostly associated with the presence of Epstein-Barr virus (EBV) and have an aggressive clinical course. Few cases of blastic NK-cell lymphoma were reported previously in Korea but there was report about blastic NK-cell lymphoma initially presented as disseminated skin lesions without any other organ involvement. We report such a young patient who was treated by systemic chemotherapy.

        항정신병약물로 야기되는 초과민성 정신병에 관한 연구

        양동균,윤진상,이형영 大韓神經精神醫學會 1989 신경정신의학 Vol.28 No.2

        Chronic antipsychotic treatment can induce tardive dyskinesia and supersensitivity psychosis, and these may be explained by supersensitivity phenomena of the dopamine receptor in the brain. This study was conducted to compare the clinical characteristics between tardive dyskinesia and supersensitivity psychosis in schizophrenia. The subjects of the study were composed of 8 schizophrenics with tardive dyskinesia(TD ), 10 schizophrenics with supersensitivity psychosis(SP), and 5 schizophrenics with both syndromes(TD with SP). They all had been treated with antipsychotics. We compared the difference in general and antipsychoti-related characteristics among the three groups. The results are as follows : 1) In the comparison of general characteristics ; There was a significant difference in the number of hospitalizations among the three groups. The number of hospitalizations was most frequent in SP group, and this was followed by TD with SP group(P<0.05). There was also a significant difference in the length of hospitalization : the longest in SP group and the shortest in TD group. Among the schizophrenic subtypes by Andreason-0lsen's criteria, the number of positive schizophrenics were significantly greater in SP and TD with SP group than in TD group(P<O.05) . 2) In the comparison of antipsychotic-related characteristics : There was a significant difference in the current antipsychotic dose among the three groups. The current antipsychotic dose was highest in SP group and this was followed by TD with SP group(P<0.05). The therapeutic response to antipsychotics was significantly better in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group(P<0.05; respectively) 3) Regardless TD, if SP was present, the serum prolactin level was significantly correlated to the current antipsychotic dose(P<0.05). 4) But, there was no significant difference in mean age, age of onset, duration, schizophrenic subtype by DSM-Ⅲ criteria, duration of antipsychotic treatment, prognosis, and antipsychotic potency among the three group.

      • 하드웨어 구현에 효율적인 블럭 정합 움직임 추정 알고리즘

        황두영,이동호 漢陽大學校 工學技術硏究所 1998 工學技術論文集 Vol.7 No.1

        본 논문에서는 3SS(Three-Step Search)와 4SS(Four-Step Search)등의 기존 고속 블럭 정합 알고리즘보다 성능이 우수하고 하드웨어 구현에 적합한 새로운 M4SS(Modified Four-Step Search) 알고리즘을 제안한다. 제안하는 알고리즘은 기존의 고속 탐색 알고리즘에 비해 연산량이 다소 많아 지지만 일정한 규칙을 갖기 때문에 하드웨어 구현에 적합하다고 할수 있다. 모의실험을 통해 기존의 고속 움직임 추정 알고리즘보다 성능이 우수하며 거의 FS(Full Search) 성능에 근접하다는 것을 확인 하였다. This paper proposes a new fast block-matching algorithm, named M4SS(Modified Four-Step Search) algorithm, which has better performance and is adequate for hardware realization than the existing fast algorithms like 3SS(Three-Step Search) and 4SS(Four-Step Search). The proposed algorithm needs a little more computations than those of the existing algorithms, but it is suitable for hadware implementation since it has a unique regularity. It is verified from simulation results that its performance is very close to that of FS(Full Search) algorithm.
