A case of unusual multilocular cystic renal cell carcinoma in a old man is reported with brief review of literature. In radiologic findings of KUB, IVP, sonogram, renal angiogram, CT scan and microscopic finding, Multilocular cystic renal cell carcinoma was confirmed.

Asphyxiating Thoracic Dystrophy에 對한 放射線學的 考察(症例報告)

林容均,裵光洙 순천향대학교 1987 논문집 Vol.10 No.1

The authors have experienced the characteristics of asphyxiating thoracic dystrophy in a newborn in the diagnostic radiologic department of our hospital recently. Initial chest film showed many features compatible with asphyxiating thoracic dystrophy. The upper ribs were short and horizontally oriented with bulbous expansion at the costochondral junction. The lower ribs flared out around the upper viscera. Overall configuration of narrow bell shaped chest and normal sized heart suggested small and underdeveloped thoracic cage. The clavicles lied highly at the level of sixth cervical vertebra horizontally. On the successive whole body film, pelvic deformities such as square-shaped iliac wings, downward hook formation on the lower border of ileum, and short ischial and public bones were acknowleged. But the vertebral column and the other long bones were not shortened, the skull was not pathologic. Autopsy findings made us confirm the diagnosis of asphyxiating thoracic dystrophy. The most prominant one of them presented the markedly small sized lungs attached to the normal sized heart. Both lungs were remarkedly hypoplastic and included a little amount of air. The bony thorax was narrow with each rib havings a bulbous expansion at the costochondral junction as same as the radiologic findings.

In this study, I wanted to explore in depth the meaning of psychological phenomena experienced by Christian living alone. For this purpose, five male and female living alone aged 65 or older were interviewed in depth, and the data after the interview was qualitatively analyzed by Giorgi's method of phenomenological research. The study found five categories : ‘feeling closer to death’, ‘loneliness due to lack of a partner to talk to’, ‘helplessness to a debilitated body phenomenon’, ‘disconnected relationships’ and ‘looking at God’. The findings that the faith proved to be an important factor of overcoming loneliness in the lives of the elderly, provide a foundation for understanding and the pastoral counseling of the elderly living alone in churches. 본 연구에서는 크리스천 독거노인들이 살면서 경험하는 심리적 현상의 의미를 심층적으로 탐색하고자 하였다. 이를 위하여 신앙생활을 하는 65세 이상 남녀 독거노인 5명을 대상으로 심층 면접을 진행하였고, 수집된 자료는 Giorgi의 현상학적 연구 방법으로 질적 분석하였다. 연구 결과, ‘죽음이 점점 가까워짐을 느낌 , 대화할 상대자가 없어 외로움, 쇠약해진 신체 현상에 무력해짐, 단절된 관계, 하나님을 바라봄의 5개의 범주가 도출되었다. 독거노인의 삶에 있어 신앙이 홀로됨을 견디게 하는 중요한 요소로 밝혀진 본 연구결과는 교회 안의 독거노인들에 대한 이해와 돌봄의 목회적 상담 기반을 위한 토대를 마련하였다고 볼 수 있다.

In order to secure traffic safety, the entire road driving process of automated vehicles must be regulated by the Road Traffic Act, and it is analyzed that there are about 50 related provisions in the current legal system. In this paper, for the systematic and effective revision of the Road Traffic Act related to commercialization of automated vehicles, the revised articles to secure traffic safety were derived based on the characteristic approach from the perspective of automated driving technology and policy, and the revised plan was reviewed and presented. First of all, case analysis was conducted on international agreements such as the Vienna Convention and policies and legislative examples of leading automated driving countries such as the United States and Germany. Based on the results of the analysis of overseas legislation cases and the overall review of the Road Traffic Act based on the technical characteristics of automated driving, the revised issues of the Road Traffic Act for safe road driving of automated vehicles were derived. Subsequently, through a multi-field expert opinion survey, the impact and considerations on the necessity of revision and the aspect of contributing to automated driving safety were analyzed. Finally, the revision plan of the Road Traffic Act related to automated driving is divided into four categories: ①driver, ②drivers, ③vehicles, and ④infrastructure articles subject to revision, contents of revision, considerations, and timing of revision were reviewed and presented. In particular, the revision plan according to the level of automated driving technology (Lv.3~Lv.5) was proposed as important matters that directly or indirectly affect various related laws such as the ｢Compulsory Motor Vehicle Liability Security Act, The Act on Special Cares Concerning the Settlement of Traffic Accident and The Product Liability Act. This paper is considered to be meaningful in that it first proposed a revision plan to the Road Traffic Act with feasibility and systemicity centered on traffic safety for the entire Road Traffic Act related to automated vehicles.

배광수 대한영상의학회 1983 대한영상의학회지 Vol.19 No.4

Spondylolisthesis is displacement of one vertebra upon the other with bony defect of neural arch or elongation of pars interarticularis. Radiological findings of 35 confirmed cases of spondylolisthesis on plain film and myelogram were reviewed. We also compared the size and contour of slipped vertebra, and myelographic findings between L4-L5 (12 cases) and L5-S1 (23 cases) listhesis. The results were as follows : 1. Average of posterior wedging index of the body, foreward displacement, narrowing of intervertebral disc space and the degenerative changes are more severe in L5-S1 spondylolisthesis. 2. Hypoplastic changes of slipped vertebra are more severe in L5-S1 listhesis. 3. Incidence of spina bifida is not co-relate between L4-L5 and L5-S1 listhesis. 4. Arthrosis of the intervertebral joint appears both below and above the level of L5-S1 listhes, but rare in L4-L5 listhesis. 5. The L5 root seems to be the one most often affected in lumbar spondylolisthesis on myelogram. 6. The diagnosis of intervertebral disc herniation is less relable in patient with listhesis than in patients without listhesis.

배광수,김규석,이재혁,이중의,조유환,박현미 대한응급의학회 2012 大韓應急醫學會誌 Vol.23 No.6

Purpose: This study was performed to evaluate whether Nterminal pro-brain-type natriuretic peptide (NT-proBNP)could predict 28-day mortality in patients with severe sepsis and septic shock. Methods: We performed a retrospective analysis of prospectively collected data from patients with severe sepsis and septic shock. Patients' demographic data, comorbidities,blood test results (including NT-proBNP concentration),and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were compared between 28-day survivors and nonsurvivors. NT-proBNP levels were categorized into quartiles by their concentration (≤600, 601 to 2,000, 2,001 to 6,000, and >6,000 pg/ml). Multivariate Cox proportional hazard regression analysis was performed to identify the predictors of mortality during a 28-day follow-up period. Results: Out of 349 patients, 117(33.5%) died. NT-proBNP concentrations were significantly higher in nonsurvivors compared to survivors (median 4,630 [IQR, 1,876-10,582]vs. 1,552 [IQR, 440-4,064] pg/ml, respectively, p<0.01). The mortality rate increased with increasing NT-proBNP concentrations; patients with NT-proBNP ≤600, 601 to 2,000, 2,001 to 6,000, and >6,000 pg/ml were 12.9%,26.1%, 39.8%, and 51.1%, respectively. By Cox proportional hazards analysis, compared to patients with the lowest NT-proBNP levels (≤600 pg/ml), patients in groups with higher NT-proBNP levels were more associated with 28-day mortality; 601 to 2,000 pg/ml (hazard ratio [HR], 1.15;95% CI, 0.50-2.63); 2,001 to 6,000 pg/ml (HR, 2.10; 95%CI, 1.05-4.81); >600 pg/ml (HR, 2.30; 95% CI, 1.15-6.14). Conclusion: NT-proBNP is an independent prognostic factor for 28-day mortality in patients with severe sepsis and septic shock.

양방향 좌회전차로(TWLTLs) 적용효과 분석 및 설치준거 연구

배광수,심관보,송창용 대한교통학회 2007 大韓交通學會誌 Vol.25 No.6

A two-way left-turn lane is a continuous center left-turn lane that could be used as a deceleration and refuge area for both directions of left-turning vehicles. TWLTL's have been used effectively for access management treatment when applied to a highway that has wide-spread left turning traffic demand and a high-density of side streets. In this study, an effective analysis was carried out using a computer-based simulation tool, VISSIM, in order to evaluate performance and safety effects of TWLTLs and develop a warrant. In conclusion, the results indicated that there was a remarkable decrease of through and left-turning vehicle travel time delay on the main road and improvement of traffic safety. 양방향 좌회전차로(TWLTLs : Two-Way Left-Turn Lanes)는 도로중앙에 양방향의 좌회전 차량이 이용할 수 있는 연속진행형 좌회전 차로가 설치된 불균등차로 시스템의 한 형태로써, 접속밀도가 높고 좌회전 교통수요가 각 회전지점별로 넓게 분산되어 있을 때 큰 운영 개선효과를 나타낼 수 있는 접근관리기법으로 알려져 있다. 본 연구에서는 양방향 좌회전차로의 국내 도입 가능성을 검토하기 위한 초기단계로써, 미시적 교통류 분석 시뮬레이션 모형인 VISSIM을 활용, 가상 네트워크와 실 네트워크에 대한 TWLTL 설치 전후 모의실험을 수행하여 운영효율 및 안전성을 평가하였으며, 이를 기초로 설치준거를 제시하였다. VISSIM 모의실험 결과, 주도로의 직진 및 좌회전 이동류에 대한 상당수준의 지체감소를 확인하였으며, 교통 안전적으로도 큰 개선효과가 있었던 것으로 분석되었다. 본 연구는 국내에서 최초로 시뮬레이션 분석모형을 활용하여 양방향 좌회전차로의 운영효과 및 안전성 개선효과를 평가하고, 교통량지체안전도를 고려한 TWLTL의 설치준거를 제시하였다는 점에서 그 의의를 찾을 수 있을 것이다.

서길수,배광수 嶺南大學校 工業技術硏究所 1982 연구보고 Vol.10 No.1

. The shear rate dependence of viscosity and primary normal stress for a dilute solution of elastic dumbbells joined by a spring has been studied for steady shearing flow. Assumption that Frenkel model can be applied to describe the spring force of elastic dumbbell has been estabished. Hydrodynamic interaction has been neglected. Giesekus expression for the stress tensor has been used. So as to calculate the expectation value of stress tensor, the differential equation of distribution function has been solved by use of perturbation method. Material functions, viscosity and normal stress, have been integrated through the orthogonal relationships of spherical harmonics. Although the crudeness of the model, the results have been qualitatively in agreement with the experimental data in the small range of shear.

수은과 N-nitrosodimethylamine 同時投與가 흰쥐胎仔에 미치는 遺傳毒性學的 硏究

裵光洙,車喆煥 고려대학교 의과대학 1991 고려대 의대 잡지 Vol.28 No.1

Co-reaction effectiveness of dimethylnitrosoamine and mercury was examined in mouse fetus to study their genotoxic effects. Mercury in the form of HgCl_2 or CH_3HgCl were given simultaneously with N-nitrosdimethylamine to mice of the 16th day of pregnancy. First part of the study examined the micronclei in polychromatic erythrocytes of fetal liver at 20hr following treatment. ln the second part of the study, Brdu(100mg /kg) was given at 24hr after treatment and DNA labelling index was determined in various fetal tissues. The results are as follows: 1. Compared to the fetal mouse liver treated only with dimethylnitrosamine,micronuclei in polychromatic erythrocytes increased about 18% when 2.50mg /kg HgCl_2 was given. when 3.20mg/kg CH_3HgCl was added, 30% increase in micronuclei was observed. 2. In the fetal tissue of lung, liver, kidney and brain, DNA labelling index by Brdu was clearly observed with simultaneous treatment with HgCl_2 or CH_3HgCl and N-dimethylnitrosamine, confirming that thsee tissues were target organs of these chemicals. InterestingIy, decrease in DNA labelling indices occurred in kidney and brain cells when mercuric compounds were added.
