한 대학병원에서 폐암으로 진단받은 환자들의 생존기간 변화에 대한 연구
이태용 충남대학교 의학연구소 2003 충남의대잡지 Vol.30 No.2
This study was conducted to investigate survival rate of lung cancer patients who have treated in a university hospital in Daejeon from 1993 to 2000. The results of this study were as follows : Sex ratio of lung cancer patients is 3.6 : 1 and 55.0% of lung cancer patients diagnosed in stage Ⅲ and 32.2% in stage Ⅳ. Survival rate by sex is higher in female than male and that by age fell dramatically in old age group. Lung cancer patients diagnosed as stage Ⅲ and stage Ⅳ had a much lower survival rate than those diagnosed as stage Ⅰ and stage Ⅱ. In conclusion, the stage at diagnosis was important factor that affect the survival rate of lung cancer patients. It is essential to develop early diagnosis of lung cancer and then it is needed to evaluate the effectiveness of that.
스포츠이벤트의 스포츠스폰서십 효과평가와 전망에 관한 이론적 고찰
이태용,조송현 釜山大學校 附設 體育科學硏究所 2009 體育科學硏究所 論文集 Vol.25 No.2
본 연구는 인간의 근원적인 욕구 및 사회현상에서 일어나는 문제점을 스포츠라는 행사를 통하여 상당부분 해소될 수 있다는 선행연구의 전제하에 여러 가지 스포츠이벤트의 스포츠스폰서십 효과평가와 전망에 대해 초점을 맞춰 이론적으로 접근하였다. 스포츠이벤트의 스포츠스폰서십은 사회적으로나 시대적인 추세에 비추어 볼 때 계속 증대될 것이며 기여도 또한 대단할 것이라고 판단된다. 고도의 기술과 전문성을 요구하는 스포츠이벤트의 스포츠스폰서십은 기획에서부터 실행까지 연구되고 전략화 되어야 할 것으로 사료된다. 이를 효율적으로 충족시키기 위해서는 사회적, 경제적, 문화적 환경에 변화에 따라 스포츠이벤트의 스포츠스폰서십에 필요한 다각적인 연구와 노력이 선행되어야 할 것이다.
Improvement of Viscoelastic Damping in Nickel Aluminum Bronze by Indium-Tin
이태용 대한금속·재료학회 2011 METALS AND MATERIALS International Vol.17 No.3
Reduction of the vibration noise from submarine propellers is of interest in naval operations. Such an objective can be achieved via the use of materials with the ability to dissipate energy of vibration by means of heat, i.e. high damping materials. An additional problem is that the extreme hydrostatic pressure environment of a submarine requires the chosen material to exhibit considerably high stiffness. Most materials demonstrate a compromise between the two properties, i.e. stiffness and damping. This paper aims to discuss research into high stiffness and high damping materials conducted using a dynamic mechanical analyzer (DMA) under variations of testing temperature, frequency, and strain amplitude. Alloys of nickel aluminum bronze and indium tin are the subjects of this study. Defect damping represents a large portion of the overall damping properties of the nickel aluminum bronze while increasing indium content is shown to boost the damping properties of the indium tin alloy. The study then continues with the development of a new material that combines both indium alloying and defects introduction into the nickel aluminum bronze alloy. The new alloy is observed to have high damping, as measured in its high tan δ, with minimum reduction of the stiffness |E*|.

Background Cardiovascular disease is becoming an important national health issue since its recent increase in incidence and mortality. The study was conducted to find out the prevalence of metabolic syndrome according to the clinical identification criteria by NCEP-ATP3 and Asia-Pacific criteria. Meterials & Methods: The subjects were 759 people -male 375 and female 384 after twenties age - who had undergone medical examinations at Korea Association of Health, Daejeon- Chungnam Branch. The prevalence of metabolic syndrome was assessed as defined by the NCEP ATP3, while abdominal obesity was assessed according to the Asia-Pacific guidelines. Anthropometric variables and cardiovascular risk factors were measured, and Associated factors with metabolic syndroms was analyzed by logistic regression analysis. Results The prevalence of metabotic syndrome was 24.O% for male and 27.1% for female The high blood pressure was the highest prevalent risk factors of metabolic syndrome. In the age group of thirties, the prevalence of metabolic syndrome was higher in men than in women, however it was significantly higher in women than in men in fifties and six ties. The metabolic syndrome was more prevalent in aged people over 50 years. and .significantly associated with BMI index(odds ratio 2.58 in male, 9.87 in female)Conclusions The prevalence of metabolic syndrome is over 20%.Early detection and intervention of risk factors by health examination and promotion are needed for prevention of metabolic syndrome.
