Carcinoma of the mouth accounts for approximately 5% of all carcinomas occurring in man. Carcinoma of the oral cavity develops as a result of invasion of malignant epithelial cells through the normally intact basal cell layer into subcutaneous and submucosal tissuse. The sofe palate and uvula may be involved in oral cancer but are not common sites. Early lesions of soft palate carcinoma appear as red, white, or mixed changes in the mucosa. The earliest symptom is mild sore throat. Advanced lesions interfer with swallowing and may cause a voice change. Although surgical method of soft palate carcinoma is successful, prognosis is relatively poor to swallowing and speech problem. Occasionally marginal recurrence may be developed. This article reports a case of squamous cell carcinoma occurred unusually in the soft palate and uvula. The case was treated with neoadjuvant chemotherapy, local radicalexcision and postoperative irradiation. Patient was followed up for 2 years. There was no tumor recurrence. The overall result including function was satisfactory.

리더 자기희생의 측정도구 개발 및 추종자의 학습효과 검증 : 대한민국 육군 장교를 대상으로

조성룡(Seong Lyong Cho),백기복(Ki Bok Baik) 대한리더십학회 2011 리더십연구 Vol.2 No.2

본 연구의 주된 목적은 리더 자기희생이 하급자(추종자)들에게 학습되고 전파되는지를 대한민국 육군 장교들을 대상으로 수행된 두 실증연구를 통하여 밝히려는 것이었다. 먼저 에서는 지휘성공사례집 등에 기초하여 군에서의 희생적 행위들을 추출한 후, 48개 기초문항들을 구성하였다. 이어서 두 차례에 걸친 군 전문가 리뷰를 통하여 최종 33개 문항을 도출한 후, 파일럿 서베이를 실시하여 요인분석을 실시한 결과, 군 리더의 자기희생은 헌신형, 직무형, 수범형의 세 차원으로 이뤄져 있음을 밝혀냈다. 에서는 을 통하여 개발된 자기희생의 측정도구를 활용하여 리더의 자기희생이 추종자들에게 학습, 전파되는지를 검증하였다. 가설검증 결과, 리더의 자기희생 및 그 하위 구성요소인 헌신형 희생, 직무형 희생, 수범형 희생은 추종자 자기희생에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 또한 추종자의 자기 효능감은 리더 자기희생이 추종자에게 학습, 전파되는 과정에서 부분매개 역할을 하는 것으로 밝혀졌다. 끝으로 본 연구의 이론적 및 실무적 의의에 대하여 기술하였고, 연구의 한계 및 향후 연구 방향을 제시하였다. The main purposes of the present study were two-fold: to develop a measure of self-sacrificial leadership and to identify how a leader's self-sacrificial behavior can be transferred to followers through the learning process. In, which purported to develop a measure of self-sacrificial leadership with Korean military officers, a series of research processes were conducted to identify leaders' self-sacrificial behaviores, ending up with a 33-item measure of self-sacrificial leadership. We also performed a pilot test with a primary military sample in order to find factors underlying the self-sacrificial leadership, resulting in three factors such as Contribution-Type Self-Sacrifice, Task-Related Self-Sacrifice, and Modelling-Type Self-Sacrifice. In, we have conducted a full-range empirical study with Korean military officers and tested hypotheses that leaders' self-sacrifice will be transferred to followers' self-sacrifice and that self-efficacy will mediate the relations between leader self-sacrifice and followers' sacrifice. And it was found that leaders' self-sacrificial behaviors are significantly associated with followers' self-sacrificial behaviors. In addition, the followers' self-efficacy was found to partially mediate the relationship between leaders' self-sacrifice and followers' self-sacrifice. Limitations of the current study and future research direction were discussed.

본 연구에서는 300톤급 추진기관 시험설비 화염유도로 기본 설계안에 대한 열적 안전성 및 연소가스의 안전한 배출을 검토하기 위하여 3차원 화염냉각 해석을 수행하였다. 화염과 냉각수 간의 열전달 및 상변화 과정을 모사하기 위하여 Mixture 다상유동모델을 이용하였으며, 단일 화학종 비반응 플룸모델을 적용하여 화염냉각 해석을 수행하였다. 본 해석결과를 통하여 화염유도로 벽면에서의 최고 온도값을 도출하였으며, 또한 연소가스가 화염유도로에 의해 외부로 안전하게 배출되고 있음을 확인하였다. In this study, a 3-D flame cooling analysis is conducted to examine a thermal safety for the flame deflector of the 300tf class propulsion test facility, and a safe discharge of the exhaust gas is assessed by using the numerical results. The Mixture multiphase model is applied for the simulation of heat transfer and phase exchange process between flame and cooling water, and a numerical analysis using the single species unreacted model for the exhaust plume is carried out for the flame cooling. The numerical analysis for the flame cooling predicts maximum temperature on the flame deflector wall, and shows the safe discharge toward exterior of the exhaust gas.

김성호,배장호,도은식,고삼규,김오룡,지용철,최병연,조수호 대한신경외과학회 1990 Journal of Korean neurosurgical society Vol.19 No.8-9

Brain Computerized Tomography(CT) and cerebral angiography were reviewed in thirty-six patients with multiple intracranial aneurysms(22.5%) among the 160 consecutive surgical cases of intracranial aneurysms. The prevalent sites of multiple aneurysms were the middle cerebral artery(37.0%). posterior communicating artery(22.2%). and internal carotid artery(14.8%) in sequence. However. the vertebrobasilar system(83.3%). anterior communicating artery(63.6%). and posterior communicating artery(50.0%) had higher probability of rupture than internal carotid artery (8.3%) or middle cerebral artery(33.3%). Based on CT and angiographic information, the site of rupture can be predicted with a high degree of reliability. These factors were the presence of localized hemorrhage on CT. focal vasospasm. size and irregularity of aneurysms. and relative hyperplasia of parent artery.

흉·요추 및 요추골절 환자에서 외과적 감압 및 기구 고정

김성호,배장호,도은식,고삼규,김오룡,지용철,최병연,조수호 대한신경외과학회 1990 Journal of Korean neurosurgical society Vol.19 No.5

최근 2년간 본 영남대학교 신경외과학교실에서 20예의 흉요추 및 요추 골절 환자의 치료를 경험하였던 바, 전방 2columns의 불안정한 척추 골절로서 척수신경이 전방의 골편에 의해 악박되고 있는 경우는 전방도달술로 감압 및 기구 고정술을 시행함으로써 보다 효과적인 결과를 기대할수 있겠고, posterior colummn의 심한 병변으로 전방에서 척수 압박이 별로 없는 불안정 척추골절의 경우는 보다더 용이한 후방도달술로 내고정을 기하는 것도 좋은 치료법이라 할 수 있겠다. Twenty patients with a major thoracolumbar or lumbar spine fractures were treated with various kinds of internal fixation device through anterior or posterior approach during last 2 years. Anterior spinal surgery(10 patients) applied to the patients who had a major fracture of anterior compartment with neural canal impingement and consisted of anterior decompression through vertebrectomy and stabilization with Kaneda device. Posterior spinal surgery(9 patients) applied to mainly posterior compartment injury and consisted of stabilization with Harrington instrumentation(3 patients) and Roy-Camille plate system(6 patients). The other one patient was treated with a combined approach of anterior decompression and posterior Harrington instrumentation. No patient showed neurological deterioration after surgery and 15 patients(75%) improved postoperatively with entering the next Frankel subgroup. Radiologic evaluation showed the correction of the fracture deformity with satisfactory outcome postoperatively. There was no significant difference between anterior and posterior spinal surgery regarding operative result.

김성룡(Seong-Lyong Kim),이준호(Junho Lee),김인선(Insun Kim),조광래(KwangRae Cho) 한국항공우주학회 2004 韓國航空宇宙學會誌 Vol.32 No.8

2002년 11월 28일 발사된 KSR-Ⅲ 과학로켓에서 공력가열로 인한 온도상승을 측정하였으며, 로켓 외피의 온도 및 공력가열량을 계산하였다. 계산에 사용된 소프트웨어는 이론식에 기초한 경계층을 해석하여 비행시간동안 비정상 공력가열량을 계산하는 MINIVER 코드이며, 비행체 내부로의 일차원 고체 열전도까지 고려하였다. 계산 결과 비행체 내부 페이로드 장착부분의 열전달은 대부분 복사로 이루어지고, 공력가열로 인한 KSR-Ⅲ 외피 최 고온도는 핀에서 223℃이며 최대 공력가열은 노즈캡에서 133㎾/㎡이었다. 중요부분에서 재질의 허용온도를 만족하였으며 외피 단열재 설계가 적절히 이루어졌음이 확인되었다. The inner surface temperatures of the KSR-Ⅲ Sounding Rocket launched at 29th November 2002 were measured in the flight test, and the aerodynamic heating rate and outer surface temperature were calculated. The used program is the MINIVER code, which calculate the boundary layer equation based on the theoretical analysis, and its calculation is simulated on the flight time histories. The analysis considered the inner surface heat transfer with one dimensional solid heat conduction. The results showed that the major interior heat transfer is the radiation heat transfer, and the maximum outer surface temperature due to aerodynamic heating reached to 223℃ at fin and the maximum heating rate is about 133㎾/㎡ at nose cap. The whole analysis proved that the surface temperature remained below the allowable temperature, and the KSR-Ⅲ thermal design satisfies the thermal environmental conditions.

Atypical Cerebellar Medulloblastoma Originating from Tentorium : Case Report

Kim, Seong-Ho,Kim, Chang-Hwan,Kim, Oh-Lyong,Chang, Chul-Hoon,Kim, Sang-Woo,Choi, Byung-Yon,Cho, Soo-Ho,Hah, Jeong-Ok 영남대학교 의과대학 2007 Yeungnam University Journal of Medicine Vol.24 No.2

The extraaxial presentation of a medulloblastoma is rare. This article descibes the case of a 12-year-old boy who presented with severe headache, nausea, and vomiting. The tumor developed in the left tentorium; it was misdiagnosed as a meningima based on the radiology examination. We review the literature and discuss the atypical presentation of medulloblastoma. 수모세포종은 주로 소뇌 충수에서 기원하는 것이 대부분이며, 천막에서 기원하는 경우는 아주 드물다. 본 보고는 심한 두통, 오심, 그리고 구토 등의 증세로 내원한 12세 남자 환자의 경우이다. 자기공명영상 검사 상 좌측 천막에서 기원한 것으로 보이는 종양이 있었으며, 이를 수막종으로 의심하고 수술적 치료를 시도하였다. 병리학적 검사 결과는 수모세포종이었다. 이에 본 저자는 천막에서 기원한 비정형적인 수모세포종에 대한 문헌고찰과 저자가 경험한 증례를 보고하고자 한다.
