        서유승,최재웅,송창섭,조용범,양진수,박준섭,정인수 대한내과학회 2003 대한내과학회지 Vol.65 No.2

        관상동맥 동정맥루 기형은 매우 드문 질환으로 치료가 불필요한 경우가 대부분이나 coronary steal 현상으로 인해 증상이 발생하거나 합병증이 발생한 환자에 대해선 치료를 요한다. 최근에는 시술에 적합한 누공을 가진 선택된 환자군을 대상으로 카테터를 이용한 중재적 시술이 시행되어 수술적 치료와 유사한 결과를 얻고 있다. 저자들은 젊은 남자에서 관상동맥 동정맥루 기형과 동반된 급성 심근 경색증을 진단하여 비 수술적 방법인 카테타 코일 색전술로 성공적 치료 후 증상 및 심근 재관류에 호전을 보인 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. We report a case of coronary fistula between the left anterior descending and main pulmonary artery complicating acute non-Q wave myocardial infarction. A 27-year-old man visited emergency department because of severe chest pain lasting two hours. The electrocardiogram showed ST segment elevation in precordial leads V3~6. Cardiac enzymes were as follows;CK-MB:36.44 IU/L T-T:0.489 ng/mL, CPK:542 IU/L, and LDH:475 IU/L. The thallium-201 dipyridamole stress perfusion scan showed perfusion defect and reversed redistribution in the anteroseptal wall. The coronary angiogram revealed coronary artery fistula between the proximal left anterior descending artery and main pulmonary artery without significant stenoses of coronary arteries. The result of ergonovine test was negative. After micro-coil embolization to the coronary fistula, symptoms were improved. Follow-up thallium-201 scan showed normalized blood flow in the left anteroseptal wall.

        제품 설계 데이터를 이용한 프레스 금형 레이아웃 설정을 위한 알고리즘에 관한 연구

        이상준,이성수 한국공작기계학회 2002 한국생산제조학회지 Vol.11 No.6

        Today most companies are designing their automobile shapes by using 3 dimensional CAD software, CATIA. And they used to design 2 dimensional press dies to do some elastic work on their products, but they are currently trying to make use of 3 dimensional software, Pro-Engineer. In this case, they have to change the 3 dimensional product design data to the proper format data for the following process. This paper will show the data loss and the deformation during data transfer between CATIA and Pro-Engineer, and then suggest a solution for these problems. Product's surface will be automatically placed by automatic press tipping angle setting in CATIA to prevent the product from being stuck in the press die. The 2 dimensional section view which is based on the tipping angle setting is created by Z-map. And, to remove the data loss and the data deformation in Pro-Engineer, the product surface are delivered to the next process after it is changed to the 2 dimensional Z-map curves in CATIA. Finally, this paper suggests an algorithm to develop the automatic design program for the press layout which regenerates product shape surface from the previous process.

        The high-speed communication backbone has the features that it is faster than any previous communication media, larger in the bandwidth and lower in the error rates. For cut-edge technical development and various service in the high-speed communication backbone, it is firstly required the technique that the multimedia informations such as texts, voices, pictures and videos are processed on real-time and then they are utilized through the connections. The future shopping and ordering system will be required as the dynamic and interactive system which can directly identify the process, size and shape of products and order, not as the static which have only texts data. And it will arise the need for the efficient management of multimedia DB. In this paper, We developed the multimedia order and sale system of agricultural and marine products. We expect that it enables to the home-shopping that users can search the informations of agricultural and marine products in home or office, and order the production after identifying with pictures and videos.

        Special education in Korea has been initiated by the education for the students with hearing impairments and the curriculum of the school for the students with hearing impairments was established in 1967. The fourth times of curriculum modification have been occurred since the fear of the first curriculum for the students with hearing impairments . The curriculum for the special school which prepared from 1998 to 2000 will be a treat influence as the education mainly for the student with disabilities which were adjusted toward the level of the students, therefore, the purpose of this study was to analyze the curriculum in the aspect of mainly focused on the class of Physical Education(PE) in the Korea special school. The curriculum of Physical Education for the students with hearing impairments was considered in just the part of the disabilities only modified from the curriculum for the public school. When the 1st curriculum was out in the field of the special education in Korea, the physical education class was regarded as an important class, however, the structure and time allocation of PE was reduced as same to the Public school. Now, in the field of special education, the PE class seemed not to be taught in the special school area. For the efficient education toward teaching the students with hearing impairments, the appropriate curriculum which will consider the conditions of each disabilities will be necessary to normalize the PE in the special school and the inservice teachers' training will be another matter to start.

        김재성,김준상,조문준,박승호,노흥태,남상륜 충남대학교 의과대학 지역사회의학연구소 1996 충남의대잡지 Vol.23 No.1

        Purpose : To evaluate survival rate, treatment failure pattern and complication of endometrial carcinoma patients treated with radiation therapy Materials and Methods : From November 1989 through March 1995, twenty two patients with endometrial carcinoma were treated with radiation therapy at Chungnam National University Hospital. According to the 1988 FIGO staging system, four patients had stage I A disease, 6 stage I B, 4 stage I C, 1 stage Ⅱ A, 6 stage Ⅲ A, and 1 stage Ⅲ B. Radiation therapy was given preoperatively to 2 patients, postoperatively to 19 patients, and curatively to one patient considered to be inoperable due to valvular heart disease. Twelve patients were treated with external radiation therapy alone by conventional technique (180-200 cGy/fraction), and 6 patients with external radiotherapy plus high dose rate intracavitary radiotherapy (HDR ICR), and 4 patients with HDR ICR alone. Results : All patients were followed up for 9 to 71 months (median 21 months). The overall 5 year survival rate of all patients was 68.9%. The 5 year survival rates of stage I , Ⅱ , and Ⅲ were 87.5%, 100%, and 41.6%, respectively. Relapse rate was 9.1% (2/22), and treatment failure occurred as a distant metastasis only without local failure. Early mild complication rate was 31.8% (7/22), and late complication rate 9.1% (2/22), including one radiation colitis and one vulvar ulcer. Conclusion : Adjuvant pelvic radiation thereapy is an effective local treatment modality to prevent local relapse in patients with endometrial carcinoma not accompanying severe late complications.

        이중혈류유발 심폐소생술이 심정지를 유발한 개의 단기 생존율에 미치는 영향

        황성오,조준휘,강구현,김성환,문중범,이강현,이승환,윤정한,최경훈,홍은석 대한응급의학회 2000 대한응급의학회지 Vol.11 No.3

        Background and Objectives: We previously reported that, compared with standard cardiopulmonary resuscitation(S-CPR), better hemodynamic effects could be achieved by simultaneous sterno-thoracic cardiopulmonary resuscitation(SST-CPR) in which we compressed the sternum and constricted the thorax circumferentially during the systolic period by using a device. This study was designed to assess whether SST-CPR, compared with S-CPR, improve the survival rate of dogs with cardiac arrest. Subjects and methods: Twenty-five mongrel dogs(19∼31㎏) were enrolled in this study. After four minutes of ventricular fibrillation induced by an AC current, animals were randomized to resuscitate with either S-CPR(n=13) or SST-CPR(n=12). Epinephrine(1 ㎎) was injected into the right atrium every three minutes after the beginning of CPR. Defibrillation was attempted after 6 minutes of CPR. Standard advanced cardiac life support was started if defibrillation was not successful. Results: SST-CPR resulted in significantly(p<0.001) higher systolic arterial pressure(91±47 vs 47±24 ㎜ Hg), diastolic pressure(43±24 vs 17±10 ㎜ Hg), coronary perfusion pressure(35±25 vs 13±9㎜ Hg), and end tidal CO2 tension(9±4 vs 3±2 ㎜ Hg). Two of 13 animals(15 %) resuscitated with S-CPR and six of 12 animals(50%) resuscitated with SST-CPR survived until 12 hours after cardiac arrest(p<0.05). Donclusion: SST-CPR, compared with S-CPR, improves the short-term survival rate in canine cardiac arrest.

      • 골수염의 진단에 있어서의 Tc-99m Hexamethylpropylene amine oxime 백혈구 스캔의 임상적 유용성

        최상호,김양수,정준원,정진원,추은주,서동대,배인규,양승오,우준희,류지소 대한화학요법학회 2001 대한화학요법학회지 Vol.19 No.1

        배경 : 골수염의 진단에 있어 Technetium-99m을 이용한 삼상 골스캔(Tc-99m MDP스캔)은 단순방사선 검사상 정상소견을 보이는 경우에 쓰이는 1차적 검사로 매우 높은 민감도를 보인다. 그러나 Tc-99m MDP 스캔은 골절이나, 정형외과적 삽입물, 신경병적 관절병변과 같이 뼈의 재형성이 증가되는 상황에서도 양성소견을 보여 특이도가 낮은 단점이 있다. 이러한 단점을 보완하고자 골수염의 진단에 있어 Tc-99m HMPAO 백혈구 스캔의 유용성을 알아보고자 하였다. 대상 및 방법 : 골수염이 의심되어 Tc-99m HMPAO 백혈구 스캔을 시행했던 15명의 의무기록을 후향적으로 분석하였다. 골수염의 확진은 임상관찰 소견과 배양검사 결과와 병리소견을 기준으로 하였다. 결과 : 골수염의 진단에 있어 Tc-99m HMPAO 백혈구 스캔의 민감도와 특이도는 각각 100%와 78%였고 Tc-99m HMPAO 스캔의 경우는 100%와 18%였다. 가장 흔한 원인균은 methicillin-resistant S. aureus였다. Tc-99m MDP 스캔에서 양성소견을 보였던 환자중 3명의 환자가 Tc-99m HMPAO 백혈구 스캔에서 음성 소견을 보였으며 이 환자들은 추적관찰상 골수염이 없는 것으로 확인되었다. 결론 : Tc-99m HMPAO 백혈구 스캔은 골수염의 존재를 진단하는데 있어 민감도와 특이도가 높으며, 특히 뼈의 재형성이 증가되어 Tc-99m MDP 스캔의 특이도가 낮게 나타나는 상황에서 유용하리라 사료된다. Background Three phase bone scintigraphy, performed with technetium-labeled diphosphonates (Tc-99m MDP scan), is the very sensitive radionuclide procedure of choice for diagnosing osteomyelitis. But, Tc-99m MDP scan is less specific when bone remodeling is increased. To overcome this limitation, we evaluated the diagnostic value of technetium-99m hexamethylpropyleneamine oxime (HMPAO) labeled leukocyte scan in osteomyelitis. Methods : We retrospectively reviewed 15 patients with suspected osteomyelitis who performed Tc-99m HMPAO labeled leukocyte scan. The diagnosis of osteomyelitis was based on clinical course and bacterial culture, and pathologic findings. Results The sensitivity and specificity of Tc-99m HMPAO leukocyte scan was 100% and 78%, and those of Tc-99m MDP scan was 100% and 18%, respectively. The most common organism was Methicilein-Resistant S. aureus. Among the patients that showed persistent accumulation on Tc-99m MDP scan, three patients showed no uptake on Tc-99m HMPAO leukocyte scan and these patients were confirmed that had no osteomyelitis. Conclusion : Tc-99m HMPAO leukocyte scan is a useful test for determining the presence or absence of osteomyelitis, especially under condition that bone remodelin is increased.

        흰쥐의 발치와에 이식한 단계별 치아싹의 발육 과정

        정희훈,정한성,김성오,최형준,이제호,최병재 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.2

        The purpose of this study is to evaluate at which stage of tooth germ would develop into normal calcification and hence to increase the success rate of transplantation. Therefore, tooth germs on the 15th, 17th embryonic day and the 3rd day of birth were separated for allotransplantation into maxilla of adult rat of 11 weeks. Calcification processes were analyzed radiographically and histopathologically at 4 weeks and 8 weeks after allotransplantation. The results are as follows: 1. Allotransplanted tooth germ at 4 weeks and 8 weeks showed delayed calcification compared to that of normal odontogenesis. 2. At 4 weeks, abnormal calcified tissue, such as odontoma and ankylosis of osteodentin with surrounding alveolar bone were observed. 3. At 8 weeks, allotransplanted tooth germs of the 15th and 17th embryonic day showed calcification and osteodentin surrounded by periodontal ligament. 4. At 8 weeks, allotransplanted tooth germs of the 3rd day of birth showed calcification composed of cementum and osteodentin. In this study, we observed small sized and amorphous calcified tissue from allotropic allotransplantation of tooth germs. Since these calcified tissue were underdeveloped and shaped irregularly, for calcification into normal tooth form, further study needs consideration about the reduction of surgical trauma, developmental stage of transplanted tooth germ, blood supply from recipient site, fixation method in transplanted site and period of transplantation. 외상이나 치주 질환,유전적 결함 등에 의하여 치아가 상실되었을 경우,보철 수복이나 임플란트로 치료하고 있다. 그러나 보철 수복이나 임플란트는 자연치가 아닌 인공치를 이용한 치료로서 기능성과 섬미성 등에서 자연치에 비하여 한계 가 있으므로 자연치를 이용한 이식 방법에 관심이 증가하고 있으며 치아 이식의 성공률을 높이기 위한 이식 치아의 발육과 성장에 대한 연구가 진행 중이다. 이 연구는 세 가지 단계의 치아싹을 발치와에 동종 이식하고 치아싹이 발육하여 석회화가 이루어지는지 평가하기 위하여 임선 15일과 17일,출생 후 3일 된 흰쥐의 치아싹을 분리하여 11주 된 흰쥐의 발치와에 이식하고 4주와 8주 후 방사 선학적 그리고 병리조직학적으로 석회화 과정을 관찰하여 다음과 같은 결과를 얻었다. 1. 발치와에 이식된 임신 15일과 17일,출생 후 3일 된 치아싹에서 4주와 8주 후 석회화된 조직이 형성되었다. 2. 임신 15일과 17일,출생 후 3일 된 치아싹을 발치와에 이식하고 4주 후 치아종 같은 비정상적인 석회화 조직과 인접 치조골과 유착된 골양상아질이 관찰되었다. 3. 임신 15일과 17일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질이 보였으며 치주인대로 둘러싸인 것도 관찰되었다. 4. 출생 후 3일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질과 백악질이 형성되었다. 이 연구는 치아싹을 흰쥐의 발치와에 이식한 후 치아싹의 발육을 관찰한 것으로 이식 조직에서 크기가 작고 무정형의 석회화 조직이 형성되었다. 정상적인 치아보다 형태가 불규칙하고 발육이 늦었으므로 이식된 치아싹이 정상적인 치아 형태로 석회화되도록 하기 위해서는 이식 조직의 발육 정도와 이식 조직을 절제할 때 외과적 손상의 감소,치아싹으로의 풍부한 혈류 공급,이삭 기간,이식 조직의 고정을 고려하여 더 많은 연구가 필요할 것으로 생각된다.
