소아의 Guillain-Barre´증후군에 대한 임상적 고찰
김태운 충남대학교 의과대학 지역사회의학연구소 1977 충남의대잡지 Vol.4 No.1
An analysis of twenty-three cases of Guillain-Barre syndrome in children, who had been observed during the 5-year period from January, 1972 to December, 1976 in the department of pediatrics of Chungnam National University Hospital, was reported. Results are as follows: 1. The incidence was highest in 3 to 6 years of age and the male to female ratio was 2.3 : 1. The majority of cases occured in 1974 and 1975. A trend toward greater incidence during summer months was observed. 2. Sixteen cases had preceding illnesses, eleven of them upper respiratory tract infection. 3. Common symptoms and signs at admission were muscular weakness or paralysis, swallowing difficulty, nuchal rigidity and sensory change in the order of frequency, and the last ones appeared in 4 cases. 4. Distributions of paralysis were as follows: lower extremities in 23 cases, upper extremities in 20, cranial nerves in 14(Ⅸ, X nerves in 12 and VI nerve in 2) and respiratory muscle in one. 5. In the cerebrospinal fluid examination of 23 cases at admission, 10 cases showed normal leukocytes counts and 13 elevations of protein level. About 1 week later, out of 12 cases, 10 showed normal leukocytes counts and elevations of protein level. 6. Of throat swabs in 9 cases, Staphylococcus aureus and group A beta-hemolytic Streptococcus were grown in 5 and 2 cases, respectively. 7. Seven cases(30.4%) showed abnormal lung findings, among which 4 were aspiration pneumonia and the remainders bacterial pneumonia, atelectasis and tuberculosis. Paralysis of Ⅸ, X nerves were the most frequent predisposing factors of them. 8. Overall recovery rate was 61% and one case died.

Product Variety Modeling Based on Formal Concept Analysis
김태운 대한산업공학회 2010 Industrial Engineeering & Management Systems Vol.9 No.1
Increasing product variety based on product family and product platform provides a company with a competitive advantage over its competitors. As products become more complex, short-life cycled and customized,the design efforts require more knowledge-intensive, collaborative and coordinating efforts for information sharing. By sharing knowledge, information, component and process across different families of products,the product realization process will be more efficient, cost-effective and quick-responsive. Formal Concept Analysis (FCA) is used for analyzing data and forming semantic structures that are formal abstractions of concepts of human thoughts. A Web Ontology Language (OWL) is designed for applications that need to process the content of information instead of simply presenting information to humans. OWL also captures the evolution of different components of the product family. The purpose of this paper is to develop product variety modeling to increase the usefulness of common platform. In constructing and analyzing product ontology, FCA is adopted for conceptual knowledge processing. For the selected product family, product variety Ontology is constructed and implemented using protégé-2000.

김태운 한국안전교육학회 1998 한국안전교육학회지 Vol.2 No.2
The purpose of this study was to assess the factors responsible for soccer injuries by examining the nature of injuries which had actually occurred to current soccer players. and to suggest practical methods of injury prevention. In an effort to analyze the various kinds of injuries suffered by soccer players, a questionnaire was designed and a total of 642 soccer players were asked to respond to 11 questions, individually. The findings were as follows: 1. Analyzing the injured parts of the body, it was found that 61%(366 person) of the players had injuries to the head in areas other than the jaw joint, and the injury of the lumber vertebrae(404 players) was the most frequent. In the case of upper-limb injuries, the wrist joint injuries were 38.5%(183 persons), 24.5%(148 persons) of the players were injured in the shoulder joint, and 23.2%(139 persons) of the players were injured in the elbow joint. 2. In the case of lower limbs, the knee joint injury exceeded 51.5%. The ankle injuries were most frequent, 78.3%(470 players out of total). 3. As mentioned earlier. most injuries in soccer were found to occur in the lower extremities. The most serious part was the sprain which included 203 players (33.8%) among the 642 research subjects. 4. The number of players injured most frequently in winter was 51.2%(307 persons). The injury which occurred on the bare ground showed the frequency of 66.7%(400 players)on the average. suggesting that a lawn be sodded on the training ground. 5. Concerning emergency treatment(first aid), the number of players who said they themselves had done emergency treatment was 46.8%(281 players). 6. The first measure to prevent injuries was indicated by the players to be enough warm up(64.2%). reinforcement of physical strength(13.3%), and good care by coaches and supervisors(10%).

김태운 한국정부학회 2012 한국행정논집 Vol.24 No.1
본 연구에서는 참여정부 이후 지역혁신정책에서 강조되고 있는 수요자 중심적 경향과 특성을 살펴보고, 정부의 수요자 지향적 정책을 추진하려는 의도가 실현되는데 장애가 되는 현실적인 문제점들이 무엇인지 분석하였다. 수요자 지향적 지역혁신정책의 특징적 요소는 지역 특화적 수요(region-specific)의 중요성, 상향식(bottom-up) 추진방식, 그리고 행위자간의 협치(governance) 등을 강조하는 것으로 요약될 수 있다. 하지만, 다양한 장애요인으로 인해 정책적 기대가 현실적으로 달성되기는 어려운 것으로 보인다. 정책의 공급 측면에서 보면, 중앙정부 정책에서의 지방수요 반영의 구조적 한계, 중앙정부의 정보능력의 한계와 정책의 획일성, 규범적 접근과 현실과의 괴리, 중앙정부의 강력한 재정 지배력 등의 문제점이 정책실현을 방해하고 있다. 수요 측면에서는 지역 개념의 모호성에 따른 지역 수요의 불명확성, 기업 및 대학의 수요 형성의 어려움, 지방의 흡수능력 차이와 지방공무원의 역량 부족 등이 주요 장애요인이 되고 있다. 이러한 문제를 극복하기 위해서는 지방에 대한 정보 확충 노력의 강화, 지방 자체의 계획수립 권한과 지방 재정보조 강화, 지역수요 발굴 및 형성 여건의 개선, 지방정부의 역량 강화 등이 필요할 것으로 보인다.

다중선형 회귀분석을 이용한 고립지역에서의 AADT 추정방안 연구
김태운,오주삼,Kim, Tae-woon,Oh, Ju-sam 대한토목학회 2015 대한토목학회논문집 Vol.35 No.4
본 연구에서는 고립지역의 과거 AADT 자료와 사회 경제지표를 활용하여 장래 AADT를 추정하였다. 과거 교통량 추이 활용 시와 사회 경제지표 활용 시 장래 AADT를 추정했으며, 사회 경제지표를 활용하여 다중회귀 분석방식을 통한 장래 AADT 추정 시 높은 설명력과 낮은 오차율을 보였다. 지리적 특성별 AADT에 미치는 사회 경제지표 분석 결과 고립일반지역은 다양한 사회 경제지표가 AADT에 영향을 미쳤으며, 고립해안지역은 유류가격과 연관성을 보이는 것으로 나타났다. 고립지역의 장래 AADT 추정 모형은 $R^2$, MAPE 분석 시 우수한 것으로 나타났다. 이는 고립지역에서는 통과 교통량이 적고 교통량 변동이 적기 때문에 사회 경제지표를 활용한 장래 AADT 추정방식이 정확하다고 볼 수 있다. This study estimates future AADT using historical AADT and socio-economic factors in isolated area. Multiple linear regression method by socio-economic factors are lower MAPE and higher R-square than using historical AADT. Analysis of socio-economic factors influence AADT in isolated typical areas, varied socio-economic factors influence on AADT. In isolated coastal areas, oil price influence on AADT. AADT forecasting model in isolated area is excellent when analysising $R^2$ and MAPE. It is assume that estimation of AADT in isolated area using multiple linear regression is accurate because of a little passed traffic volume and traffic volume fluctuation.
