서영우,김기혁 대한교통학회 2008 대한교통학회지 Vol.26 No.5

Bus passengers need some time to adapt to the changed bus route or free bus transfer system which is part of the public transportation system restructuring plan. This research is focused on the characteristics of monthly patterns of bus passengers. The period of stabilization of bus passenger demand after the rearrangement of bus route system by a time series were analysed. In order to look into the characteristics of bus passenger demand by month, data on the number of monthly bus passengers of recent five years in metropolitan cities across the nation was collected. Kendall's coefficient of concordance is used to test whether the cities showed concordance with respect to the number of monthly bus passengers during a period of five years. The study collected and performed a time series analysis of data on the number of monthly bus passengers during the past ten years in Daegu metropolitan area which carried out a new bus route plan in February 2006. The number of monthly bus passengers in 2006 was estimated using the time series analysis. The city of Daegu found that after six months the estimated and actual values displayed a similar pattern. This result can be applied to other cities in estimating the passenger demands in the future. 버스노선개편 및 환승요금무료와 같은 대중교통체계개편을 실시함에 따라 시내버스 이용자들이 개편된 노선에 익숙히 대처하기 위해서는 일정기간이 소요된다. 따라서 본 연구는 시내버스 승객수요의 월별 특성에 대해 분석하고, 시계열분석을 실시함으로써 버스노선개편 이후에 변화하는 시내버스 승객수요가 다시 안정된 월별특성을 나타내기까지의 기간에 관하여 연구하고자 한다. 먼저 여러 도시들의 시내버스 승객수요가 공통된 월별 특성을 나타내는지 분석하기 위해 켄달의 일치계수검정을 실시하였다. 또한 노선개편으로 인해 변화된 승객수요가 일정한 패턴을 보이는 기간을 분석하기 위해 시계열분석으로 예측된 2006년의 시내버스 월별 승객수와 실제 집계된 시내버스 월별 승객수를 비교하였다. 이에 따라 각 도시들은 공통된 월별 특성을 보이는 것으로 분석되었고, 대구광역시는 약 6개월 뒤에 예측값과 실제값이 같은 패턴으로 변화하는 것으로 분석되었다. 본 연구는 타도시에서도 적용이 가능하며 시내버스 승객수요의 미시적인 예측과 평가에 활용될 것으로 기대된다.

서영우,박한솔,김민철,김세영,서영훈,이상민,김유종,홍제락,김지수,김기옥,김태훈 대한침구의학회 2015 대한침구의학회지 Vol.32 No.2

Objectives : This study is an evaluation of the effectiveness of treatments combined with Korean medical methods, such as relaxative Chuna and Gangchuk herbal medicines, for patients with failed back surgery syndrome. Methods : In this study, medical records of ten patients who experienced failed back surgery syndrome and participated in intensive Korean medical treatment were reviewed. All patients received relaxative Chuna and acupuncture along with Gangchuk herbal medicines during hospitalization. Numeric rating scale(NRS) in the degree of 0 to 10, pain-free walking distance(PFWD) and oswestry disability index(ODI) were measured before and after treatments. Results : The patients were hospitalized for an average of 22 days. The average NRS of lumbar pain in all patients decreased from 7.7±1.6 to 3.2±2.2 and the average NRS decline of leg pain was from 7.7±1.7 to 3.2±2.2, both of which indicate statistical significance(p < 0.05). PFWD in all patients increased from 113.3 m to 798.1 m on average. The average ODI in all patients significantly improved from 63.9±7.0 to 43.9±6.9(p < 0.05). Conclusions : The treatments combined with Korean medical methods for failed back surgery syndrome patients are clinically effective and viable.

병원외 심정지 후 자발순환회복 환자의 관상동맥조영술 결과

서영우,장태창,이경원 대한응급의학회 2011 대한응급의학회지 Vol.22 No.5

Purpose: Coronary artery disease is the most common cause of out-of-hospital cardiac arrest (OHCA). Primary percutaneous coronary intervention (PCI) is currently the most effective reperfusion strategy in acute myocardial infarction. The decision to perform PCI in an unconscious resuscitated OHCA patient is challenging because of uncertainty of the clinical course, status of the coronary artery and prognosis. The study evaluated clinical characteristics,angiographic findings and results of OHCA patients who were successfully resuscitated and underwent PCI. Methods: A retrospective study was performed from January, 2008 to December, 2010. Thirty four OHCA patients who successfully resuscitated and followed by PCI were enrolled. They were divided into significant and nonsignificant coronary artery group. Significant coronary artery group (n=23) was subdivided into survival and mortality subgroup. Results: Twenty three of the 34 patients had significant coronary disease on coronary angiography. There was no significant difference between the two groups in clinical and electrocardiography (ECG) findings based on age, sex,presence of chest pain, initial ECG, and ECG after return of spontaneous circulation (ROSC). The significant coronary artery group displayed higher creatine kinase-MB and troponin-I levels, and more common presence of ventricular fibrillation (VF) prior to PCI. The survival subgroup showed a lower number of significant stenotic coronary arteries, better neurologic finding prior to PCI and lower levels of cardiac biomarkers such as creatine kinase-MB and troponin-I. Conclusion: PCI after ROSC in OHCA patients with presumed ischemic cardiac etiology may be reasonable, even in the absence of a definite clinical and ECG finding. The presence of VF or serial cardiac biomarkers is helpful in deciding whether to perform PCI.

Chronic silica nephropathy has been associated with tubulointerstitial disease, immune-mediated multisystem disease, chronic kidney disease, and end-stage renal disease. On the other hand, acute intentional exposure is extremely rare. The authors’ experienced a 44-year-old man who took rapid cement hardener (sodium silicate) in a suicide attempt whilst in a drunken state. He visited the emergency department approximately 1 hour after ingestion. Information on the material was obtained after 3 L gastric lavage. The patient complained of a sore throat, epigastric pain, and swollen to blood tinged vomitus. Proton pump inhibitors, hemostats, steroid, and fluids were administered. Nine hours after ingestion, he was administered 200 mL hematochezia. Immediately after, a gastroenterologist performed an endoscopic procedure that revealed diffuse hyperemic mucosa with a color change and variable sized ulceration in the esophagus, whole stomach, and duodenal 2nd portion. Approximately 35 hours later, persistent oligouria and progressive worsening of the renal function parameters (BUN/Cr from 12.2/1.2 to 67.5/6.6 mg/dL) occurred requiring hemodialysis. The patient underwent 8 sessions of hemodialysis for 1 month and the BUN/Cr level increased to 143.2/11.2 mg/dL and decreased to 7.6/1.5 mg/dL. He was discharged safely from the hospital. Follow up endoscopy revealed a severe esophageal stricture and he underwent endoscopic bougie dilatation. Acute cement hardener (sodium silicate) intoxication can cause renal failure and strong caustic mucosal injury. Therefore, it is important to consider early hemodialysis and treatment to prevent gastrointestinal injury and remote esophageal stricture.
