From the results of tracer test for the existing chlorine contactor in Y water treatment plant, T10 and T10/T were calculated as 130 min and 0.16, respectively. Therefore it required the modification schemes for improving hydraulic efficiency, surrogated by T10 and T10/T, and disinfection performance. In this study, in order to reduce dead zone within contactor, the installation of porous baffles in the near of each corner was suggested and verified using transient CFD(Computational Fluid Dynamics) simulation technique and tracer tests on dynamic condition. From the results of simulation and tracer tests, it was revealed that porous baffles installed have been effective to reduce dead zone within contactor, and increase plug flow fraction.

박현오,최준영,장인석,김종덕,최재원,이정은 대한흉부외과학회 2019 Journal of Chest Surgery (J Chest Surg) Vol.52 No.6

Background: For decades, trauma has been recognized globally as a major cause of death. Reducing the mortality of patients with trauma is an extremely pressing issue, particularly for those with severe trauma. An early and accurate assessment of the risk of mortality among patients with severe trauma is important for improving patient outcomes. Methods: We performed a retrospective medical record review of 582 patients with severe trauma admitted to the emergency department between July 2011 and June 2016. We analyzed the associations of in-hospital mortality with the baseline characteristics and initial biochemical markers of patients with severe trauma on admission. Results: The overall in-hospital mortality rate was 14.9%. Multivariate logistic regression analysis showed that the patient’s Rapid Emergency Medicine Score (REMS; odds ratio [OR], 1.186; 95% confidence interval [CI], 1.018–1.383; p=0.029), Emergency Trauma Score (EMTRAS; OR, 2.168; 95% CI, 1.570–2.994; p<0.001), serum lactate levels (SLL; OR, 1.298; 95% CI, 1.118– 1.507; p<0.001), and Injury Severity Score (ISS; OR, 1.038; 95% CI, 1.010–1.130; p=0.021) were significantly associated with in-hospital mortality. Conclusion: The REMS, EMTRAS, and SLL can easily and rapidly be used as alternatives to the injury severity score to predict in-hospital mortality for patients who present to the emergency department with severe trauma.

박현오,김성환,문성호,양준호,강동훈,이정희 대한흉부외과학회 2017 Journal of Chest Surgery (J Chest Surg) Vol.50 No.4

In the embryo, the thymus originates from the third and fourth pharyngeal pouches and migrates from the superior neck to the mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue, and is caused by the aberrant migration of the embryonic thymus. Our patient was a 30-year-old woman who had a nodular lesion in the neck for several years. Ultrasonography and computed tomography were performed. She underwent surgery, and a histological examination resulted in a diagnosis of type AB thymoma. Herein, we report a case of ECT that was resected through a transcervical approach.

We report a rare case of dyspnea caused by a cardiac tumor in a 53-year-old woman. The patient had undergone a cardiac tumor (inflammatory myofibroblastic tumor, 6.2 × 4.2 × 3.3 cm) resection at our institute 13 months earlier. We performed preoperative evaluations which revealed a cardiac tumor originating from the posterior wall of the left atrium. Cardiac autotransplantation surgery (cardiac explantation, ex vivo tumor resection, cardiac reconstruction, and cardiac reimplantation) was successfully performed for the complete resection of the recurrent tumor without major postoperative complications. The patient showed good physical conditions for 21 months after the surgery. Cardiac autotransplantation is a safe and feasible technique for the complete resection of complex left atrial tumors.

Association between Body Mass Index and Sputum Culture Conversion among South Korean Patients with Multidrug Resistant Tuberculosis in a Tuberculosis Referral Hospital

박현오,김성환,문성호,변정훈,김종우,이정은,김종덕,장인석,양준호 대한감염학회 2016 Infection and Chemotherapy Vol.48 No.4

Background: Multidrug-resistant tuberculosis (MDR-TB) is an important global health problem. Furthermore, the time to identify a positive sputum culture is an important risk factor for the spread of tuberculosis, and several factors can predict a prolonged time to culture conversion. Moreover, the relationship between poor nutritional status and infectious disease is clearly established. Therefore, the present study aimed to investigate the association between body mass index (BMI) and sputum culture conversion within 3 months among patients with MDR-TB. Materials and Methods: We retrospectively evaluated 218 patients with MDR-TB who were treated at a large tuberculosis referral hospital in South Korea between January 2005 and December 2010. The outcome of interest was defined as sputum culture conversion within 3 months, and we analyzed the association between BMI and this outcome. Results: Among the 218 patients, 53 patients (24.3%) had a low BMI (<18.5 kg/m2). In the multivariate Cox proportional-hazards regression analysis, failure to achieve sputum culture conversion within 3 months was independently associated with having a low BMI (hazard ratio [HR]: 1.741, 95% confidence interval [CI]: 1.006–3.013; P = 0.047) and a positive sputum smear at the initiation of therapy (HR: 8.440, 95% CI: 1.146–62.138, P = 0.036). Conclusion: Low BMI (<18.5 kg/m2) was an independent risk factor for failure to achieve sputum culture conversion within 3 months among patients with MDR-TB.

This study aims to provide necessary informations for the establishment of proper political measures to stabilize domestic hog production. For this, a structural analysis was performed using a recursive system model and the results obtained can be summed up as follows. 1. The number of sow turned out to be determined by farm price of fattening hog and price of feed. It takes about a year before a pig is born and fattened to be slaughtered. This means that the supply in period t is not determined by current market price, but by an expected price of the previous year. This again implies that the stabilization of both pork and feed prices is essential for the balanced production of pork. 2. The number of slaughtered hog plays an important role in determining consumer price as well as farm price of fattening hog. This is due to the fact that the number of slaughtered hog determines supply. The above-mentioned implies that production and market controls to meet the seasonal demands are inevitable to keep the price changes within tolerable ranges. 3. The expenditure elasticity of pork turned out to be inelastic revealing 0.68. This might be partially attributable to the fact that per household instead of per capita expenditure was used, mainly due to data restriction. Anyhow, development of high-quality pork proce-ssing technology is needed to accelerate the consumption of pork. This is particularly important considering that pork explains more than half of total domestic meat consumption and more pork products are expected to be imported following the trade liberalization.

박현오,문성호,김종우,변정훈,김성환,양준호,이정은,김종덕 대한혈관외과학회 2016 Vascular Specialist International Vol.32 No.4

Hypercoagulable states have been associated with aortic thrombosis. Antipho-spholipid syndrome (APS) is one of the commonest types of acquired throm-bophilia. We report the case of successful anticoagulation management in an APS patient with mobile thrombi within the aorta. A 58-year-old male patient presented to the emergency department (ED) with right-sided hemiparesis. His first symptoms were noted approximately 12-16 hours before presentation to the ED. Magnetic resonance imaging of the brain showed acute embolic infarction of the left frontal and parietotemporal lobes. Transesophageal echocardiography (TEE) and computed tomography angiography (CTA) demonstrated mobile thrombi attached to the wall of the ascending aorta and aortic arch. The patient was diagnosed with APS based on positivity of anti-beta-2 glycoprotein 1 antibodies, and was initiated on anticoagulation therapy. Repeated TEE and CTA revealed complete resolution of the thrombi after 12 days of treatment; the patient was discharged well.

박현오,강동훈,문성호,양준호,김성환,변정훈 대한흉부외과학회 2017 Journal of Chest Surgery (J Chest Surg) Vol.50 No.5

Background: Ventilator-associated pneumonia (VAP) is a common disease that may contribute to morbidity and mortality among trauma patients in the intensive care unit (ICU). This study evaluated the associations between trauma factors and the development of VAP in ventilated patients with multiple rib fractures. Methods: We retrospectively and consecutively evaluated 101 patients with multiple rib fractures who were ventilated and managed at our hospital between January 2010 and December 2015, analyzing the associations between VAP and trauma factors in these patients. Trauma factors included sternal fracture, flail chest, diaphragm injury, traumatic aortic dissection, combined cardiac injury, pulmonary contusion, pneumothorax, hemothorax, hemopneumothorax, abbreviated injury scale score, thoracic trauma severity score, and injury severity score. Results: Forty-six patients (45.5%) had at least 1 episode of VAP, 10 (21.7%) of whom died in the ICU. Of the 55 (54.5%) patients who did not have pneumonia, 9 (16.4%) died in the ICU. Using logistic regression analysis, we found that VAP was associated with severe lung contusion (odds ratio, 3.07; 95% confidence interval, 1.12 to 8.39; p=0.029). Conclusion: Severe pulmonary contusion (pulmonary lung contusion score 6–12) is an independent risk factor for VAP in ventilated trauma patients with multiple rib fractures.
