Main character of the Anak Tomb No.3, Dong-su is from unknown family in China, but he was charged with a top position where only elite worked as in Murong(慕容) regime. That was unusual, so this researcher called his background in question. As the result of analyzing various family names-related data, Dong-su was not from China but from Nakranggun. At that time, Chinese immigrants and original settlers who are Goguryeo’s descendants lived in Nakranggun, and Dong-su was also one of original settlers. Meanwhile, the history book reveals Dong-su’s birthplace as Yodong. When King Micheon of Goguryeo ruled Nakranggun(樂浪郡) in 313, among residents of Nakranggun, there were immigrants who moved to Yoseo in China and they settled themselves in Nakranggun that was newly established near to Geuksung(棘城). Besides, they were immgrated in Changryeogun(昌黎郡) and Yodonggun(遼東郡). As the result, Nakrang Han family received a new domicile of Changryeo Han family, and Nakrang Dong family was changed to Yodong Dong family, which was the reason that Dong-su was expressed as Yodong. For Goguryeo that subjected Nakranggun, controlling powerful families(豪族) who were main power of Nakranggun was the main point. Goguryeo carried through the Nakranggun governance by using the graded powerful family Dong(冬) to restrain Nakranggun large family Wang(王). They received administrative rights from the Goguryeo regime, but military rights were totally under Goguryeo. Han(韓) and Wang(王) families that were ruled like this became the sacrificial lamb of the reinforcement policy of kingship and received a blow after King Jangsu(長壽王) moved the capital from Kuknaesung to Pyeongyang. The fact was turned out in inscription remaining in China through the analysis of the study. As the result, they left Nakrang for China. After that, these two families weakened as much as their trace was not found in the history of the late Goguryeo. However, some people from Nakranggun who just followed Goguryeo’s rule played a important role after the late Goguryeo.

`Purpose: To investigate whether there are differences in ocular risk factors reportedly associated with the development of normal tension glaucoma (NTG) between glaucomatous eyes and normal visual field (VF) eyes of monocular NTG patients. Methods: Thirty-six patients who had NTG in one eye and normal RNFL and VF in the fellow eye were included in this hospital-based cross-sectional retrospective survey. We analyzed the difference between glaucomatous eyes and normal VF eyes according to an intra-individual, inter-ocular comparison of ocular parameters, including intraocular pressures (IOP), central corneal thickness (CCT), optic disc size, myopia, optic disc hemorrhage, and zone β of peripapillary atrophy. Measurements of optic disc size and area and the angular and radial extent of zone β were obtained using a Heidelberg Retina Tomograph. We also evaluated the correlation of each parameter with mean deviation (MD) and pattern standard deviation (PSD). Results: There were no inter-ocular differences of IOP, CCT, optic disc size, or myopia (n=36). Optic disc hemorrhage was found in only three glaucomatous eyes. The area of zone β was greater in glaucomatous eyes than in normal VF eyes (p=0.003). No parameters were correlated with MD or PSD. Conclusions: Except for optic disc hemorrhage and zone β area, all other parameters showed no inter-ocular differences. The asymmetry of disc hemorrhage and zone β area in monocular NTG patients implies that optic disc ischemia might play a role in the pathogenesis of NTG.`

목 적 : 알레르기성 자반증 환아에서 상부위장관 내시경 소견을 관찰하고, 또한 위장관 증상이 있는 환아와 없는 환아에서 상부위장관 내시경 소견의 차이가 있는지 보고자 이 연구를 시행하였다. 방 법 : 1996년 9월부터 2002년 10월까지 계명대학교 동산병원 소아과에 입원하였던 알레르기성 자반증 환아 중 위장관내시경 검사를 실시한 65명을 대상으로 하였다. 위장관 증상의 유무에 따른 내시경 소견을 비교 관찰하였으며 피부 병변 3일 전부터 퇴원까지의 기간 동안 복통, 구토, 위장관 출혈, 설사 등의 증상을 기록하여 위장관 증상의 유무를 판단하였다. 결 과 : 위장관 내시경을 시행한 65명 중 위장관 증상이 있던 환아는 53명이었고, 증상이 없는 환아는 12명이었다. 6-10세 연령군이 많았고 위장관 증상은 남아에서 그리고 증상으로는 복통과 구토가 많았다. 위장관 내시경을 시행한 65명 중 십이지장 점막에 이상 병변의 빈도가 가장 높았으며, 병변의 양상에 따른 빈도는 십이지장염 12명, 위염과 십이지장염 9명, 십이지장미란 6명, 위염 5명, 십이지장궤양 5명, 위궤양 2명, 결장미란 1명의 순으로 관찰되었으며 정상소견은 25명이었다. 증상이 있던 환아 53명 중 38명에서 그리고 증상이 없던 환아 12명 중 2명에서 위장관 내시경 소견상 이상 소견을 보였다. 결 론: 위장관 증상이 있는 알레르기성 자반증 환아에서는 내시경 검사를 시행하는 것이 병변의 진단과 치료에 도움이 되었으나 더 많은 예에서 연구가 필요하리라 생각된다. Purpose : This study was performed to analyze the endoscopic findings in Henoch-Schonlein purpura patients, and to compare the differences in endoscopic findings according to age and gastrointestinal symptoms. Methods : We examined children with Henoch-Schonlein purpura aged 3 to 15 years between September 1996 and October 2002. The total number studied was 65, consisting of 41 boys and 24 girls. Endoscopy was performed and the results were analysed. Results : Among 65 cases, 12 cases of duodenitis, nine cases of gastritis and duodenitis, six cases of duodenal erosion, five cases of gastritis, five cases of duodenal ulcer, two cases of gastric ulcer and one case of colonic erosion were noted. Endoscopic abnormality was found in 38 of 53 who had gastrointestinal symptoms, and in two of 12 who didn't have gastrointestinal symptoms. Conclusion : Most of the gastrointestinal symptoms in Henoch-Schonlein purpura patients were relieved without complication. But in some cases severe symptoms such as hematemesis, melena, and abdominal pain localized to epigastric area were developed when diagnosis was delayed. Prompt endoscopy will be helpful for diagnosis and therapy of Henoch-Schonlein purpura with gastrointestinal involvement.

저자들은 특징적인 진찰 소견과 피부 조직 생검에서 제 I형 교원질 유전자 발현의 감소를 보인 Goltz 증후군 1례를 경험하였기에 보고하는 바이다. Goltz syndrome(focal dermal hypoplasia) is a rare disorder characterized by ectodermal and mesodermal dysplasia described in 1962 by Goltz. In Korea, one case of Goltz syndrome was reported in 1994. The inheritance mode is mostly X-linked dominant. Skin abnormality is the most common manifestation including hypoplasia of the dermis. Skeletal involvement such as syndactyly, polydactyly, scoliosis, kyphosis and spina bifida occulta may be present, also ocular and dental abnormalities are reported. Radiologic findings are the osteopathy and striation of the long bone. We experienced a case of Goltz syndrome in a 9-year old female who was presented with right side hypotrophy, focal dermal hypoplasia, ocular(anidria, microcornea), dental(oligodontia, amelogenesis) and skeletal(syndactyly) abnormalities. Skin biopsy was performed and showed decreased expression of type I collagen gene with Northern blotting.

이동훈,박지원,홍철표,Lee, Dong-Hoon,Park, Ji-Won,Hong, Cheol-Pyo 대한물리치료학회 2013 대한물리치료학회지 Vol.25 No.5

Purpose: This study was conducted in order to evaluate the quantitative effectiveness of region of interest (ROI) setting in MR-DTI analysis with and without fMRI activation results. Methods: Ten right-handed normal volunteers participated in this study. DTI and fMRI datasets for each subject were obtained using a 1.5T MRI system. For neural fiber tracking, ROIs were drawn using two methods: The drawing points were located in the fMRI activation areas or areas randomly selected by users. In this study, the neural fiber tract targeted the corticospinal tract (CST) Quantitative analyses were performed and compared. The pixel numbers passing through the fiber tract in the individual brain volume were counted. The ratios between the ROI pixel numbers and the extracted fiber pixel numbers, and the ratios between the fiber pixel numbers and the whole-brain pixel numbers were also calculated. Results: According to our results, extracted CST fiber tract in which the ROI was drawn with fMRI activation areas showed higher distribution than drawing the ROI by users' hands. In addition, the quantitatively measured values represented higher pixel distribution: The counted average pixel numbers were 4553.8 and 1943.3. The average ratios of the ROI areas were 33.87 and 22.52. The average percentages of the individual whole-brain volume numbers were 2.06 and 0.87. Conclusion: Results of this study appear to indicate that use of this method can allow for more objectives and significant for study of the recovery of neural fiber mechanisms and brain rehabilitation.

이동훈,송근성,Lee, Dong Hoon,Song, Geun Sung 대한신경외과학회 2001 Journal of Korean neurosurgical society Vol.30 No.12

Objective : In the retrospective analyzing 19 consecutive patients with subaxial cervical spine(C3~T1) injury treated by posterior cervical fixation and fusion, clinical manifestation, radiologic finding, operative technique, and postoperative results following 6 months were analyzed. Materials and Methods : Most common fracture level was C4-5, mean age 41, and male to female ratio 13 : 6. The most common cause of injury was motor vehicle accident(17 cases). In 19 cervical procedures, interspinous triple wiring was done in 14 cases, lateral mass plating in 5 cases, and additional anterior fusion in 2 cases. Results : Twelve weeks after operation, all cases were reviewed by plain cervical radiogram. In 17 cases that treated by posterior fusion only, 14 cases(81%) had kyphotic angle change less than $5^{\circ}$, 2 cases(12%) $5-20^{\circ}$, and 1 case(6%) more than $20^{\circ}$. Overall fusion rate was 88%, and there was no significant difference of bone fusion rate between autogenous bone graft and allogenous bone graft. Conclusion : In the case of severe posterior column injury or displacement, posterior approach seems superior to anterior approach, but in the case of combined anterior column injury, anterior approach is considered necessary. In this study, posterior fixation and fusion might be acceptable procedure for subaxial cervical fracture and dislocation, owing to its high fusion rate, low kyphotic angulation and low operation related complication rate.

국내 건설산업 특성을 고려한 기업의 벤치마킹 프로세스

이동훈,김선국,최재휘,이원석,Lee, Dong-Hoon,Kim, Sun-Kuk,Choi, Jea-Hwi,Lee, Won-Suk 한국건설관리학회 2010 한국건설관리학회 논문집 Vol.11 No.6

벤치마킹은 기업의 경쟁력 향상 및 경영전략수립을 위한 효과적인 도구이나 대상과 방법이 적절치 못한 경우 그 실효성이 저하될 수 있다. 건설업의 경우 제조업과는 생산과 경영구조 그리고 수익구조 등 여러 가지 측면에서 다르기 때문에 다른 방식의 벤치마킹이 필요하다. 국내 건설업의 특성은 동일 유형의 경쟁기업이 다수 존재하고 법규 및 정책 등 외부환경변화에 영향을 많이 받는 등 다양하다. 따라서 건설기업의 벤치마킹은 특성상 기업군을 대상으로 하는 것이 효율적이며 자료수집 시자기업의 성과인 내부자료와 벤치마킹 대상의 성과인 기업자료 뿐 아니라 외부환경변화자료도 수집되어야 하며 기업 간 성과 비교 시 외부환경변화가 반드시 고려되어야 한다. 건설업 특성상 건설기업은 차입금과 자기자본 비율의 변화가 크기 때문에 최적자본구조에 대한 분석도 필요하다. 본 연구는 이와 같은 건설업 특성과 국내 기업의 상황을 분석하여 기존의 벤치마킹 프로세스와 차별된 건설기업 벤치마킹 프로세스를 제안한다. Benchmarking is an effective tool supporting improvement of corporate competitiveness and development of management strategy, however, its effectiveness may be compromised if its target and approach are not appropriate. Notably, the construction industry of Korea is unique in that it has a number of competitors sharing the same category and is significantly exposed to changes in external environment in terms of legal, regulatory and policy frameworks. Such characteristics make target corporate category rather than single company more suitable as benchmarking target and necessitate analysis of external environment. This study intends to analyze the characteristics of construction industry in Korea and conditions of domestic companies in order to propose a benchmarking process for construction industry differentiated from conventional ones.학교 건축공학과, 산학협력기술연구원;경희대학교 대학원;경희대학교 대학원;

국내 건설기업의 경영 및 조직현황 분석

이동훈,김선국,김만기,신동화,Lee, Dong-Hoon,Kim, Sun-Kuk,Kim, Man-Ki,Shin, Dong-Hwa 한국건설관리학회 2010 한국건설관리학회 논문집 Vol.11 No.1

국내 건설기업들은 최근 금융위기, 미분양 주택의 증가 등 외부적인 경영환경의 악화로 많은 어려움을 겪고 있다. 이러한 경영환경의 변화에 대처하기 위하여 기업은 환경의 변화에 신속하고 탄력적으로 적응할 수 있는 효율적인 경영조직의 구성이 필요하다. 그러나 대부분의 기업은 조직에 대한 분석과 이해가 부족하여 사업 물량과 유형에 따라 경영조직을 구성하고 있다. 국내 시공능력순위 30위 이내의 건설기업들 역시 서로 다른 경영조직과 사업구조를 가지고 있으며 또한 각기 다른 경쟁력과 위기요인도 가지고 있다. 따라서 본 연구는 건설기업의 경영 및 조직현황을 조사하여 경영성과와 조직특성을 파악하고 효율적인 경영전략 수립과 기업의 경영조직을 구성하기 위한 기초자료를 제공하고자 한다. Builders in Korea are facing significant challenges in the midst of deteriorating market conditions resulting from recent financial crunch and slumping housing sales, etc. To address such changes in management landscape, enterprise organizations need to build an efficient corporate management organization than can ensure prompt and flexible response to changes in surroundings. However, most of them base their management organization on business type and volume due to insufficient understanding and analysis of organization. Top 30 construction companies in Korea have their own management organizations and business structures let alone different competitive edges and challenges. Therefore, this paper attempts to examine the current status of management and organization of construction companies to understand their operational achievements and organizational features in and effort to develop an efficient management strategy and provide inputs contributory to establishment of corporate management organization.
