본 연구에서는 다양한 설계조건 하에서 철골보의 내화시간을 평가할 수 있는 산정식을 열-구조 연성해석(fully coupled thermo-mechanical analysis)을 토대로 제안하였다. 본 연구에서 제안하는 산정식은 철골보의 화재거동에 미치는 주요 인자를 구조변수 및 열변수로 명시적으로 반영하므로 각 설계변수의 내화성능에 대한 영향을 설계자가 쉽게 정량적으로 파악할 수 있는 강점이 있다. 광범위한 변수해석을 수행하기에 앞서 실물대 화재실험 결과를 활용하여 본 연구의 열-구조 연성해석모델의 타당성을 검증한 후, 철골보에 붕괴처짐(run-away deflection)이 발생할 때까지 화재거동에 대한 각 변수들의 영향력을 검토하였다. 이러한 수치해석결과를 다양한 설계조건에서 철골보의 내화시간 예측에 활용할 수 있도록 다중선형회귀분석을 통해 통계학적으로 신뢰도가 높은 평가식을 제안하였다. 현행 사양설계기준에서의 활용법을 사례를 들어 예시하였고, 제시된 식으로부터 얻어지는 경제성과 장점을 입증하였다. This paper proposes a versatile formula which can be used to evaluate the fire resistant time of steel beams under various design conditions. Towards this end, the key parameters which affect the fire performance of steel beams were first determined through thermo-mechanical considerations, and classified into two groups: structural parameters and thermal parameters. Then the degree of influence of each parameter on the fire performance was investigated through a fully coupled thermo-mechanical analysis up to the occurrence of run-away deflection. The accuracy of the numerical model used was verified using an available full-scale fire test before conducting an extensive parametric analysis. Multiple linear regression analysis was performed to obtain the formula which can be used to predict the fire resistance time of steel beams under various design conditions. The statistical analysis showed that the proposed formula is very robust. The application of the formula in practical fire design under the current code was illustrated in detail. The economy and other advantages of the proposed formula were clearly shown.

Purpose: To calculate Preventable Trauma Death Rate (PTDR), Trauma and Injury Severity Score (TRISS) is the most utilized evaluation index of the trauma centers in South Korea. However, this method may have greater variation due to the small number of the denominator in each trauma center. Therefore, we would like to develop new indicators that can be used easily on quality improvement activities by increasing the denominator. Methods: The medical records of 1005 major trauma (ISS >15) patients who visited 2 regional trauma center (A center and B center) in 2014 were analyzed retrospectively. PTDR and PARK Index (Preventable Major Trauma Death Rate, PMTDR) were calculated in 731 patients with inclusion criteria. We invented PARK Index to minimize the variation of preventability of trauma death. In PTDR the denominator is all number of deaths, and in PARK Index the denominator is number of all patients who have survival probability (Ps) larger than 0.25. Numerator is the number of deaths from patients who have Ps larger than 0.25. Results: The size of denominator was 40 in A center, 49 in B center, and overall 89 in PTDR. The size of denominator was significantly increased, and 287 (7.2-fold) in A center, 422 (8.6-fold) in B center, and overall 709 (8.0-fold) in PARK Index. PARK Index was 12.9% in A center, 8.3% in B center, and overall 10.2%. Conclusion: PARK Index is calculated as a rate of mortality from all major trauma patients who have Ps larger than 0.25. PARK Index obtain an effect that denominator is increased 8.0-fold than PTDR. Therefore PARK Index is able to compensate for greater disadvantage of PTDR. PARK Index is expected to be helpful in implementing evaluation of mortality outcome and to be a new index that can be applied to a trauma center quality improvement activity.

Purpose: This study aimed to investigate the characteristics of patients attempting suicide and to analyze treatment determination factors for patients with mental illness who go to an emergency center for treatment. Methods: Data collected from 117 suicide attempters who visited Busan Regional Emergency Medical Center were analyzed using frequency, percentage, χ²-test with SPSS/WIN 15.0. Results: Only 31 cases consulted with the psychiatric department; the other attempters’ refused to consult (26.5%). Among the 31 attempters who consulted, 23 cases (74.2%) were suffering from depression. The most common reason (38.6%) suicidal attempters gave to refuse psychiatric treatment was “I’m not mad. I don’t need the psychiatric treatment.” Treatment determination factors for mental illness were religion (p<.001), past history (p=.017), financial satisfaction (p=.048), previous history of suicidal attempts (p=.006), sleep disturbance (p<.001), expression of suicide (p=.010), and type of leaving the emergency room (p=.020, p<.001). Conclusion: Results suggest that people frequently misunderstand psychiatric treatment which leads to their refusal to accept psychiatric treatment. Therefore hospitals need to develop standard guidelines and procedures for suicidal attempters with the collaboration of emergency and psychiatry departments. In addition, medical teams need to provide attempters appropriate information and encourage them to actively seek psychiatric treatment.

의료서비스와 IT 기술간의 융합으로 환자 개인의 건강정보가 전자의무기록(EHR)의 보급과 함께 빠르게 전자화되고 있다. 이와 함께 유헬스사회에 접어들면서 전자화 된 환자의 건강기록들을 진료 이외의 공중보건 및 의학 분야의 연구, 의료서비스 향상을 위해 사용하고자 하는 2차이용의 요구가 증가하고 있다. 개인건강정보의 2차이용으로 의학분야의 발전은 매우 유익한 일이지만 부주의하게 개인의 건강정보를 이용하는 경우 환자 개인의 프라이버시 손상이 발생, 더불어 2차이용을 통한 연구나 서비스 발전에도 제한이 발생할 수 있다. 하지만 아직 개인건강정보를 이용한 2차적 이용에 대해 체계적인 연구나 논의가 없는 것이 현실이다. 따라서 본 논문에서는 개인건강정보의 2차이용과 관련하여 국내외의 법안들을 살펴보고 이를 비교 분석하여 앞으로 개인의 프라이버시를 존중하고 더불어 의료분야 서비스의 발전을 도모할 수 있는 방향을 제시하고자 한다. Through the convergence of medical services and the IT technique, the patient’s personal health information computerization has been rapidly spread with propagation of electronic medical record(EHR). In addition, by entering u-health, the demand of the secondary use for public health, medical research, and medical service using electronic patient health care records are increasing. The personal health information secondary uses for the development of academic medical area and service, are very good thing. But, carelessly to use personal health information, the patient privacy would be damaged. However, there are not yet systematic studies about secondary use of personal health information. Therefore, in this paper, we analyze the difference of the internal and external bill for personal medical data secondary use and propose the direction of the medical service development and preservation of the individual's privacy.
