The purpose of this study is to present the effective smoke control flow rate and mode for securing safety through quantitative risk assessment according to the smoke control flow rate and mode (supply or exhaust) of the platform when a train fire occurs at the subway platform. To this end, a fire outbreak scenario was created using a side platform with a central staircase as a model and fire analysis was performed for each scenario to compare and analyze fire propagation characteristics and ASET, evacuation analysis was performed to predict the number of deaths. In addition, a fire accident rate (F)/number of deaths (N) diagram (F/N diagram) was prepared for each scenario to compare and evaluate the risk according to the smoke control flow rate and mode. In the ASET analysis of harmful factors, carbon monoxide, temperature, and visible distance determined by performance-oriented design methods and standards for firefighting facilities, the effect of visible distance is the largest, In the case where the delay in entering the platform of the fire train was not taken into account, the ASET was analyzed to be about 800 seconds when the air flow rate was 4 × 833 m³/min. The estimated number of deaths varies greatly depending on the location of the vehicle of fire train, In the case of a fire occurring in a vehicle adjacent to the stairs, it is shown that the increase is up to three times that of the vehicle in the lead. In addition, when the smoke control flow rate increases, the number of fatalities decreases, and the reduction rate of the air supply method rather than the exhaust method increases. When the supply flow rate is 4 × 833 m³/min, the expected number of deaths is reduced to 13% compared to the case where ventilation is not performed. As a result of the risk assessment, it is found that the current social risk assessment criteria are satisfied when smoke control is performed, and the number of deaths is the flow rate 4 × 833 m³/min when smoke control is performed at 29.9 people in 10,000 year, It was analyzed that it decreased to 4.36 people.

Streptococcus pneumoniae is a major cause of serious invasive diseases in children, especially in young infants, but seven- valent pneumococcal conjugate vaccine (PCV7) is believed to prevent invasive pneumococcal pneumonia and meningitis in young children. However, recently, the incidence of non-PCV7 serotype has increased after PCV7 vaccination. A 14-month- old female patient presented at our emergency room with mental change and lethargy. Three days previously, she had developed fever and vomiting. After being admitted, she rapidly progressed to coma and brain death despite prompt and extensive supportive treatment. She expired 20 days after admission with a final diagnosis of pneumococcal 19A (non-PCV7 serotype) meningoencephalitis despite having received PCV7 ($Prevenar^{(R)}$) vaccinations on three occasions. The author reports this first fatality due to pneumococcal 19A meningoencephalitis in Korea and provides a brief review of the literature.

Leptospira isolated from patients and natural paddy water were further studied to confirm their serologic specificity with the bacteria in infected animal tissue and autopsied tissue of patients died with leptospirosis. And pathologic patterns of the inoculated antimal and the virulence of the bacteria in the animals were also studied. The findings are summarized as follows; $LD_{50}$ dose of the bacteria in guinea-pig were $1-2{\times}10^9$ cells and mice were found to be susceptible to them even though the degree of susceptibilities were much inferior to guinea pig. The bacteria were recovered from various organs; demonstrated massive hemorrages due to diapedesis and monocyte infiltration were observed, in some cases, intramedullary hemorrages of the infected kidnies and hematuria were recognized. All of the hyperimmune sera were strongly reacted with the tissues from autopsied human case who died of EPHF(Epidemic Pulmonary Hemorrhagic Fever) in immunofluorescent antibody tests.

COVID-19 has recently impacted the world with the large numbers of infected and deaths. The development of effective COVID-19 vaccine has not been successful. Hence, people have a high concern on the infection of this disease. The infection information from the governmantal public organizations are mainly based on simple summary statistics. Consequently, it is hard to assess the infection risks of individual person and the current location of the person. In this paper, we present a machine learning-based software system that analyzes COVID-19 infection risks and guidelines for safe activities.This paper proposes a suite of risk factors regarding COVID-19 infection and deaths and methods to quantitatively measure the individual and group risks using the proposed metrics. The proposed system utilizes a clustering algorithms and various software approaches that reflect the information and features of inviduals and their geograpical locations.

Traumatic pelvic injuries usually include high-energy crush injuries and are associated with significant morbidity and mortality. Mortality rates range from 6% to 15% and increase to 36%-54% in cases of fractures that result in increased pelvic volume. Therefore, retroperitoneal hemorrhage can spiral and progress to hemorrhagic shock. Pelvic hemorrhage most commonly occurs secondary to disrupted pelvic veins or fractured bones, and 10%-20% of cases involve arterial injuries. Owing to extensive bleeding and limitations of surgery for pelvic hemorrhage, interventional treatment is at the forefront of pelvic hemorrhage management. CT is an accurate indicator of active hemorrhage in patients with pelvic trauma that affects the diagnosis and management, including interventions. Identification of the site of hemorrhage is necessary for focused interventional treatment. The current trend toward a more conservative approach for treatment of pelvic trauma and advances in interventional radiology in the field of pelvic trauma may favor widespread use of interventional treatment for patients with pelvic injuries. In this review, we discuss therapeutic modalities available to the interventional radiologist and common angiographic treatment strategies and techniques.

Backround : Pneumoconiosis is the parenchymal lung disease that results from the inhalation and deposition of dust, usually mineral dust of occupational or environmental origin. Most of the pneumoconiosis can be categorized to coal workers' pneumoconiosis (CWP) in Korea. No effective treatement is currently available, and the therapy for symptomatic CWP is limited to treatment of complication. Therefore authors analyzed and reviewed clinical features and radiological findings of 95 patients with pneumoconiosis for assessing the prognostic factors in disease progression. Method: We reviewed medical records of 95 cases with pneumoconiosis including history, chest X-ray, pulmonary function test, electrocardiography, AFB stain and culture of sputum, and routine blood examination between June 1995 and June 1997 in Seonam University Namkwang Hospital. Results: All of cases are male(mean age, 57.4 years), 91 cases out of them are miners. The mean duration of exposure to dust is 18.8 years. Major clinical symptoms are dyspnea (100%), sputum (71.6%), chest pain (55.8%), cough (23.2%), and hemoptysis (6.3%). 82 % of cases are over Morgan-Seaton Grade 2 in the degree of dyspnea. Small opacity on chest x-ray is 82.1 % and large opacity is 17.9%. Small opacity has tit type (37.2%), q/q type (25.6%) and r/r type (11.5%). B type is 42.2% in large opacity. For the pulmonary function test, restrictive type is 40.3%, mixed type 19.5% and obstructive type 8.3%. The more increasing chest Xray density, the more decreasing $FEV_1$ (p<0.01). 38% of patients show tuberculosis in chest X-ray, 15.8% positive smear of acid fast bacilli in sputum. The prevalence of pulmonary tuberculosis is high in patients with poor clinical condition. The cases with the active pulmonary tuberculosis have severe dyspnea. Expired cases show 100% and 75% of positive pulmonary tuberculosis in chest X-ray and sputum examination, respectively. 75% of expired cases show the chronic cor pulmonale, who died of acute respiratory failure. Conclusion: These findings indicate that tuberculoois infection has a decisive influence on the progress and prognoois of pneumoconioois.

Objectives : To evaluate the clinical significance of abnormal bronchi originating from the trachea or main bronchi. Methods : 21 patients (male:female ratio, 13:8; mean age, 58.2 years, range 34-77), who were diagnosed with major tracheobronchial anomalies by bronchoscopy from January 2001 to March 2005, were enrolled in this study. The anomalous bronchi consisted of 13 tracheal bronchi and 8 cardiac accessory bronchus. The clinical features, bronchoscopic findings, and outcomes were analyzed retrospectively. Results : Common symptoms, including hemoptysis, cough and dyspnea, resulted from the underlying lung disease regardless of the bronchial anomalies. In this series of 13 tracheal bronchi, 7 cases originated from the trachea within 1cm of the carina (carinal type) and 6 cases originated at a higher level(tracheal type). Most patients had favorable outcome with conservative treatment for the underlying lung disease. Conclusion : Most tracheobronchial anomalies are found incidentally in the process of diagnosing lung disease. The clinical outcome of patients with a bronchial anomaly depends on the underlying lung disease.

Against major release of radioactive material in nuclear power plant, Emergency Planning Zone(EPZ)s are typically established around nuclear power plants to effectively perform the public protective measures. The domestic methodology to determine the size of the EPZ is similar to that of Japan established in 1980, where calculations were based on the conservative accident source term. The objective of this study is to re-evaluate the validity of established EPZ, the area within the radius of $8{\sim}10km$ around domestic nuclear power plants, using the source terms covering full spectrum of accidents obtained from PSA study of ULJIN 3&4. To evaluate the risks of health effects, the computer code MACCS2(MELCOR Accident Consequence Code System2) was used. The result shows that the existing EPZ can reduce the probability of early fatality adequately for most of the source term categories(STCs) except for STC-14 and STC-19. In case of STC-14 and 19, the evacuation distance of 16km and 13km, respectively, are required. These distances can be reduced by improving emergency preparedness since the sensitivity studies for the public protective actions show that the magnitude of early fatality is largely affected by the time delays in notification and evacuation.

This paper estimates the health life expectancies for Korean people based on a sample cohort database collected through objective measurements by the National Health Insurance Service. Health life expectancy is estimated using the single-state approach of Sullivan (1971). The 9-order correction factor method of Greville (1945) and Brass-logit model of Brass (1971) are also adopted for unobserved or incompletely observed age-specific morbidity and mortality. Based on the mortality and morbidity estimated from sample cohort DB, men and women in Korea are expected to live a 'healthy life' for 61 and 60 years in 2013, respectively, whereas life expectancies of men and women are 80 and 87, respectively. We also estimate certain disease-free life expectancies for each of genders, income levels, and types of insurance from 2003 to 2013 in Korea. We found that there exists an inequality of healthy life expectancy in Korea for different genders, income levels, and types of insurance.
