A dissecting aneurysm of the vertebral artery may be treated conservatively, surgically, or using an endovascular approach. Proximal clipping, wrapping or trapping are surgical treatment methods, and endovascular treatment with coils and balloons is performed where a dissecting aneurysm is located near the midline or the appropriate surgical manipulation is difficult. As the contralateral vertebral artery of this patient was hypoplastic, the stent-assisted coil embolization techique was employed to preserve the ipsilateral vertebral artery. We describe a clinical case of dissecting aneurysm of the vertebral artery occurring in a patient in whom a hypoplastic contralateral vertebral artery was successfully treated. 추골동맥의 박리성 동맥류에 대한 치료는 보존적, 수술적 및 혈관내 치료법 등이 있다. 수술적 치료법으로는 근위부 결찰(proximal clipping), 포장(wrapping), 또는 포착(trapping) 등이 있으며, 위치적으로 적절한 수술적 치료가 어려운 경우에는 코일이나 풍선을 이용하여 근위부 폐색을 시행하는 혈관내 치료가 대체치료방법으로 이용되고 있다. 본 증례에서는 반대측 추골동맥이 저형성되어 있었으므로 환측 추골동맥을 보존하면서 박리성 동맥류를 치료해야 하므로 스텐트를 도움으로 혈관내 코일색전술을 시행하였으며 그 결과가 성공적이었기에 이를 보고하고자 한다.

정해웅 대한영상의학회 1999 대한영상의학회지 Vol.40 No.2

Purpose : To analyze the abnormal findings of brain MR imaging seen in Wilson's disease. Materials and Methods: The authors retrospectively reviewed the MR imaging findings (location, signal intensity and contrastenhancement of lesions, and brain atrophy) of nine patients with Wilson's disease confirmed by neurologicalsymptoms, laboratory findings and physical examination. Results : The putamen, midbrain, pons and middlecerebellar peduncle were involved bilaterally and symmetrically in all nine patients, and the thalamus(6/9),corpus callosum(5/9), globus pallidus(3/9), posterior limb of the internal capsule(3/9), superior cerebellarpeduncle(3/9), caudate nucleus head(2/9), subcortical white matter(2/9) and medulla oblongata(1/9) were involvedin decreasing sequence. In all patients, the signal intensity of lesions was low on T1-weighted image and high onproton density- and T2-weighted images. Three patients with contrast enhancement showed no definite enhancement oflesions. Diffuse brain atrophy involving the cerebrum, cerebellum and brain stem was found in three patients.Conclusion : Knowledge of the characteristic MR findings of Wilson's disease is helpful in differentiating otherdiseases involving similar locations.

정해웅,은충기,심재홍 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5

Purpose : To analyze the result in the treatment of intracranial aneurysms by using Gughelmi detachable coils(GDCs). Materials and methods : We reviewed 29 intracranial aneurysms in 27 patients attempted by GDCs embolization between March 2002 to February 2003. There were 8 males and 19 females, who ranged in age from 18 to 71 years(mean age 52.5 years). 15 patients(55.6%) presented with hemorrhage, 8 patients(29.6%) with incidental finding, and 4 patients(14.8%) with nonhemorrhagic symptom. This series consisted of small(<12mm), and three large(12∼25mm) aneurysms. Aneurysm neck size divided into narrow-(8 cases) and wide-necked(>4mm or neck/aneurysm ratio>0.5, 21cases) aneurysms. Of the 15 patients in whom hemorrhage occurred, 3(20%) presented with Hunt and Hess Grade Ⅱ, 11(73.3%) with Grades Ⅲ and 1(6.7%) with Grades Ⅵ. The locations of the aneurysms were basilar bifurcation(9 cases), parachinoid internal carotid artery(4 cases), posterior communicating artery(4 cases), superior cerebellar artery, posterior inferior cerebellar artery, P2 segment of posterior cerebral artery, cavernous internal carotid artery(2 cases), vertebrobasilar junction, vertebral artery dissection, M1 segment of middle cerebral artery, anterior communicating artery, internal carotid artery bifurcation, and supraclinoid internal carotid artery(1case). Indications for use of the GDCs were location and surgical difficulty(15, 51.7%), surgeon's preference(4, 13.8%) and unruptured condition(10, 34.5%). Results : Of the 29 aneurysms attempted by GDC embolization, 25 aneurysms were successfully treated. The technical success rate was 86.2% (25/29). The causes of technical failure were aneurysm with wide neck in 3 cases and parent vessel tortuousity in 1 case. The length of clinical follow up ranged from 0 to 11 months(average, 4.9 months). In 19(76%) patients, good clinical outcomes were achieved. There were 4 fair outcomes (16%) and 1 poor outcome(4%) due to initial severe hemorrhage. One death(3.7%) were recorded due to ventriculitis and other medical problems. The mortality and morbidity rates directly related to the intervention were 0% and 6.9%, respectively. Angiographic studies were obtained immediately after intervention. Complete or almost complete(99∼100%) occlusion were observed in 19 cases(76%), a greater than 90% occlusion was seen in 4 cases(16%) and a less than 90% occlusion was seen in 2 cases(8%). Technical complications were observed in 5 cases(17.2%) including aneurysm perforation in 1 case, unintentional parent artery occlusion in 1 case, and coil protrusion in 3 cases. Follow-up angiograms were obtained in 4 patients between 6 to 7 months(average 6.8 months) after coil placement. Angiographic recanalization was not seen in all cases and there was no significant interval change compared with immediate postintervention angiography. Conclusion : Endovascular treatment of incranial aneurysms by using GDCs led to excellent clinical and angiographic results in majority of patients. Long-term follow-up studies are necessary to assess effectively the value of GDCs as definitive treatment for intracranial aneurysms.

외향성 정도가 직무만족과 집단응집에 미치는 영향: 육군사관학교 동아리 활동의 조절효과를 중심으로

정해웅,강원석 이화여자대학교 경영연구소 2016 신산업경영저널 Vol.34 No.2

이 연구는 최근 기업들뿐만 아니라 군 조직에도 활성화 및 정착돼 가고 있는 동아리 활동 부서를 중심으로, 조직 구성원의 외향성 정도와 직무만족 및 집단응집 간의 관계를 규명하고 외향성과 동아리 활동 부서 종류의 유의미함을 정확히 인식하고자 하였다. 군 조직의 동아리 활동 정책 및 계획 수립에 있어 올바른 전략을 제시하기 위해 우리는 육군사관학교 동아리 활동에 참여하는 사관생도들을 대상으로 그들이 속한 동아리 활동 부서의 종류와 외향성 정도, 그리고 동아리 활동에 대한 직무만족과 집단응집을 조사하였다. 연구 결과, 동아리 활동에 참여하는 사관생도들의 외향성 정도가 높을수록 동아리 활동에 대한 직무만족과 집단응집이 높았으며, 각 부서의 종류라고 할 수 있는 세 가지 위원회는 각각 독립변수와 종속변수 사이에서 조절효과를 가지고 있었다. 다양한 성격 요인들을 독립변수로 했던 기존의 연구들과 달리 본 연구는 외향성이라는 개별 요소에 초점을 맞추었다는 점과 더불어 동아리 활동의 종류, 즉 조직의 활동 성격을 조절변수로서 함께 고려했다는 점에 의의가 있으며, 정책적으로도 군 조직 내 동아리 활동 정책이 나아가야 할 방향을 제시하였다는 점에서 의의가 있다. This study aims to investigate the relationship between the KMA cadets' degree of extroversion, job satisfaction, and group cohesion. This study suggests an effective strategy for the establishment of club activity policy, plan settling down not in companies but also in the military, and understand the meaningfulness of the concept of extroversion and the types of club activities. As a result, it was proven that as cadets' degree of extroversions are higher, the more positive they answered as to their job satisfaction and group cohesion. Moreover, three committees of the club activities was proven to contain the regulation effect between the independent and dependent variables. Unlike the most of existing studies which utilized the diverse personality factors as the independent variable, this study focused on separate element of extroversion. Additionally, this study considered the type of club activities - in other words, the organization's character of activity - thus, have its own relevance. Due to these facts, the result of this research is meaningful in terms of proposing the promising perspective of policies on club activities in KMA as well as the Korean military.

정해웅,김창수,Jeong, Hae-Ung,Kim, Chang-Su 대한영상의학회 2001 대한영상의학회지 Vol.45 No.5

목적:뇌간을 침범한 다발성 경화증의 MR소견을 분석하여 진단에 도움이 될 수 있는 소견이있는지 알아보고자 하였다. 대상과 방법:MR을 시행한 다발성 경화증 환자 35예 중에서 뇌간을 침범한 20예(57%)를 대상으로 뇌 MR영상소견을 후향적으로 분석하였다.대상환자는 남자가 8명,여자가 12명이었고, 연령분포는 25세에서 59세로 평균 37.5세였다.MR영상에서 뇌간 및 뇌간외 병변의 침범부위, 신호강도,다발성유무,모양,조영증강유무 등을 알아보았고,뇌간 병변의 뇌조(cisternal)혹은 뇌실(ventricular)뇌척수액 공간과의 근접성(contiguity)유무를 분석하였다. 결과:20예 중 5예(25%)에서 뇌간만 침범되었으며 나머지 15예(75%)에서는 뇌간외 다른 부위의 침범이 있었다.뇌간 중 중뇌 혹은 연수만을 침범한 예는 없었으며,중뇌,뇌교와 연수를 동시에 침범한 경우가 12예(60%)로 가장 많았다.뇌간 각 부위의 침범 빈도는 연수 18예(90%),뇌교 17예(85%),중뇌 16예(80%)이었다.신호강도는 전예에서 T1강조영상에서 저신호 강도를,T2,양자농도 및 FLAIR영상에서 고신호 강도를 보였다.뇌간 병변은 17예(85%)에서 다발성으로 관찰되었다.병변의 모양은 원형,난원형,타원형,반점형(patchy),반달형(crescentic),융합형(confluent),무정형(amorphous)으로 다양하였으며,관상면이나 시상면 영상을 얻었던 17예중 14예(82%)에서 상하로 긴 막대형(tubular)병변이 관찰되었다.뇌간 병변과 뇌조(cisternal)혹은 뇌실(ventricular)뇌척수액 공간과의 근접성은 중뇌와 연수 병변의 경우 전예(100%)에서 관찰되었고,뇌교 병변의 경우 15예(88%)에서 관찰되었다.조영증강을 시행한 12예중 7예(58%)에서 뇌간 병변의 조영증강이 관찰되었다. 결론:뇌간을 침범한 다발성 경화증은 MR영상에서 다양한 모양을 보이는 다발성 병변의 전부 혹은 일부가 뇌조 혹은 뇌실 뇌척수액공간과 접하거나 상하로 긴 병변이 시상면 혹은 관상면에서 관찰된다. Purpose: To describe MRI findings of multiple sclerosis involving the brainstem.Materials and Methods: Among 35 cases of clinically definite multiple sclerosis, the authors retrospectively analysed 20 in which the brainstem was involved. MR images were analysed with regard to involvement sites in the brainstem or other locations, signal intensity, multiplicity, shape, enhancement pattern, and contiguity of brainstem lesions with cisternal or ventricular CSF space. Results: The brainstem was the only site of involvement in five cases (25%), while simultaneous involvement of the brainstem and other sites was observed in 15 cases (75%). No case involved only the midbrain or medulla oblongata, and simultaneous involvement of the midbrain, pons and medulla oblongata was noted in 12 cases(60%). The most frequently involved region of the brainstem was the medulla oblongata (n=18; 90%), followed by the pons (n=17; 85%) and the midbrain (n=16; 80%). Compared with normal white matter, brainstem lesions showed low signal intensity on T1 weighted images, and high signal intensity on T2 weighted, proton density weighted, and FLAIR images. In 17 cases (85%), multiple intensity was observed, and the shape of lesions varied: oval, round, elliptical, patchy, crescentic, confluent or amorphous areas were seen on axial MR images, and in 14 cases (82%), coronal or sagittal scanning showed that lesions were long and tubular. Contiguity between brainstem lesions and cisternal or ventricular CSF space was seen in all cases (100%) involving midbrain (16/16) and medulla oblongata (18/18) and in 15 of 17 (88%) involving the pons. Contrast enhancement was apparent in 7 of 12 cases (58%). Conclusion: In the brainstem, MRI demonstrated partial or total contiguity between lesions and cisternal or ventricular CSF space, and coronal or sagittal images showed that lesions were long and tubuler.
