Objective: Traumatic epidural hematomas (EDHs) in children are a relatively unusual occurrence. The cause and outcome vary depending on period and reg ion of study. The aims of this analysis were to review the cause and outcome of pediatric EDHs nowadays and to discuss outcome-related variables in a large consecutive series of surgically treated EDH in children. Methods: This is a retrospective review of 29 patients with surgically treated EDHs between Jan 2000 and February 2010. Patients' medical records, computed tomographic (Cl) scans, and, if performed, magnetic resonance imaging (MRI) were reviewed to define variables associated with outcome. Variables included in the analysis were age, associated severe intracranial injury, abnormal pupillary response, hematoma thickness, severity of head injury (Glasgow Coma Scale score), parenchymal brain injury, and diffuse axonal injury. Results: The mean (SO) age of the patients was 109 months (0-185 months). Most of the injuries with EDHs occurred in traffic accident (14 cases, 48.2%) and followed by slip down in 6 cases and falls in 6 cases. There were one birth injury and one unknown cause. EDHs in traffic accidents occurred in pedestrians hit by a motor vehicle, 9 cases; motorbike and car accidents, 5 cases and bicycle accidents, 1 case. The locations of hematoma were almost same in both sides (left side in 15 cases). Temporal lobe is the most common site of hematomas (13 cases, 44%). The mean size of the EDHs was 18 mm (range, 5-40 mm). Heterogeneous hematomas in CT scans were 20 cases (67%). Two patients were referred with unilateral or bilateral dilated pupil(s). There was enlargement of EDH in 5 patients (17%). All of them were heterogeneous hematomas in CT scans. Except for 4 patients, all EDHs were associated with skull fracture(s) (87%). There was no case of patient with major organ injury. CT or MRI revealed brain contusion in 5 patients, and diffuse axonal injury in one patient The mortality was zero, and the outcomes were excellent in 26 and good in 2 patients. None of the tested variables were found to have a prognostic relevance. Conclusion: Regardless of the EDH size, the clinical status of the patients, the abnormal pupillary findings, or the cause of injury, the outcome and prognosis of the patients with EDH were excellent.

Accidents are the fourth-leading causal factor of death among the elderly, and fall is a major type of accident (53.17%). Many cases of falls in the elderly result in delayed discovery and loss of quality of life. As the number of the elderly grows, falls will be a more important health problem. Most previous research on falls investigated prevalence. mortality, and the related factors. There are many studies proving the effect of rhythmic movements. But few researches considered linking risk factors of fall with rhythmic movements. Purpose: We want to show the changes after performing rhythmic movement program, in risk factors of falls and mobility such as flexibility, balance, muscle power and persistency in the elderly, in order to provide basic information needed for the development of fall injury prevention program for the elderly. Method: The design of this study is quasi-experimental, the equivalent control group, pretest-posttest. The subjects consist of 124 people who lived in Do-Bong-Qu. Seoul, agreed to participate in this study, and were able to follow this rhythmic movement program. About 93 % of them are from 65 to 84 years (Mean${\pm}$sd: $73.7{\pm}5.7$): 64% are female. The rhythmic movement program was designed. and performed by two community health nurses working in the Do-Bong-Gu Public Health Center, regularly twice a week from May, 4 to December, 17. in 10 senior citizens' community centers. Risk factors of fall were measured with RAFS- II (Risk Assessment for Falls Scale II) by asking about each item: mobility was measured by observing their specific movements asked by investigators. Results: 1. After performing the program during 7 months, risk factors score of falls were decreased significantly (paired-t = 4.77. p<0.01). 2. After performing the program during 7 months, flexibility (paired-t = 2.26. p=0.03) and mobility were improved (paired-t = 4.98. p<0.01). but muscle power and persistency did not change (paired-t = 0.33. p=0.74). Overall, mobility affecting the occurrence of falls was improved significantly (paired-t = 5.15. p<0.01). Conclusions: A regular rhythmic movement program can be helpful in preventing falls in the elderly. Further. we can develop a fall injury prevention program using rhythmic movement.

Recently, advanced metering infrastructure (AMI) has been recognized as a core technology of smart water grid, and the relevant market is growing constantly. In this study, we developed all-in-one smart water meter of the AMI system, which was installed on the test-bed to verify both effectiveness and field applicability in office building water usage. Developed 15 mm-diameter smart water meter is a magneto-resistive digital meter, and measures flow rate and water quality parameters (temperature, conductivity) simultaneously. As a result of the water usage analysis by installing six smart water meters on various purposes in office building water usage, the water usage in shower room showed the highest values as the 1,870 L/day and 26.6 liter per capita day (LPCD). But, the water usage in laboratory was irregular, depending on the many variables. From the analysis of the water usage based on day of the week, the water usage on Monday showed the highest value, and tended to decrease toward the weekend. According to the PCA results and multivariate statistical approaches, the shower room (Group 3) and 2 floor man's restroom sink (Group 1-3) have been classified as a separate group, and the others did not show a significant difference in both water use and water quality aspects. From the analysis of water usage measured in this study, the leak or water quality accident did not occur. Consequently, all-in-one smart water meter developed in this study can measure flow rate and water quality parameters (temperature, conductivity) simultaneously with effective field applicability in office building water usage.

Purpose: Recently, trauma is more frequent due to the increases in the population, the number of traffic accident, and the incidence of violence. Especially, abdominal trauma is a leading cause of morbidity and mortality. We analyzed the clinical features and the factors associated with morbidity and mortality. Methods: We analyzed 136 patients of abdominal trauma who were admitted at the Department of Surgery, Chonnam National University Hospital, from January 2003 to June 2005. We analyzed the cause of trauma, the injured organ, combined injuries, mental status, blood pressure, laboratory findings, morbidity, and mortality. The relationships between by variable were assesed by using the independent samples test and the Kruskal?Wallis test. Results: The causes of trauma were traffic accidents (98 cases, 72%), falling accidents (9 cases, 6.6%), violence (6 cases, 4.4%), and stab injuries (6 cases, 4.4%). The injured organs were the small intestines (47 cases, 34.6%), the liver (35 cases, 25.7%), the spleen (26 cases, 19.1%), the mesentery (17 cases, 12.5%), the large intestines (15 cases, 11.0%), the pancreas (14 cases, 10.3%), etc. The most common combined injury was chest injury (53 cases, 39%). Comatose or semicomatose mental status and shock on admission (<60 mmHg in systolic) were related to high mortality (85.7%). In laboratory findings, decreased hemoglobin (<8 g/dL), and platelet count (<$50,000/mm^3$), and increased creatinine level (>1.6 mg/dL) were significant prognostic factors. The incidence of postoperative complications was 40.4%, and frequent complications were wound infection (8.1%) and re-bleeding (8.1%). The overall mortality rate was 18.4%, and most common cause was hypovolemic shock (18 cases, 13.2%), however, there was no statistical difference according to injurd organ. Conclusion: In the multivariate analysis, mental status, hemoglobin, and serum creatinine level were the most significant prognostic factors. When an abdominal trauma patient arrives at the emergency room, a rapid and accurate evaluation of the patient's status and risk factors, and resuscitation, if necessary, have to be performed to lower the morbidity and mortality.

세계적으로 충돌, 테러, 화재, 폭발 등의 극한하중에 의한 테러가 빈번하게 발생하고 있으나, 실제 극한하중에 대한 사회주요기반시설구조물의 방호 및 방재개념이 설계에 반영되고 있지 못하는 실정이다. 특히, 교량, 터널, 원전격납구조물, 가스탱크 등의 주요 시설물에 적용되고 있는 프리스트레스트 콘크리트(PSC) 구조물에 대한 극한하중 연구는 미흡한 실정이다. 또한, 테러, 폭격, 차량 및 선박 등의 충돌 사고 이후 2차적으로 발생 가능한 화재에 대한 사회적 관심 및 불안감이 고조됨에 따라, 단순한 단일 극한하중이 아닌 복합손상 시나리오에 대한 구조물의 검토가 필요하다. 그러므로, 본 연구에서는 $1,400{\times}1,000{\times}300mm$ 부재의 양방향에 430kN의 긴장력을 준 비부착 프리스트르레스트 콘크리트 패널부재를 제작하여, 충돌, 화재 하중 뿐만 아니라, 충돌 후 화재의 복합손상을 실험적으로 검토하였다. 이방향 프리스트레스트 콘크리트의 충돌저항성능은 실험조건에 맞춰 14kN의 추를 10m, 3.5m의 높이의 실험으로 구성하였으며, 화재저항성능은 5분 이내에 $1,200^{\circ}C$의 화재하중을 가할 수 있는 RABT 화재 시나리오를 적용하여 극한저항성능을 검토하였다. 또한 충돌, 화재, 충돌 후 화재에 의해 손상을 받은 PSC 및 RC 시편의 잔류구조성능을 손상 받지 않은 시편들과 비교 검토하였다. 본 실험은 향후 국내외 프리스트레스트 콘크리트에 대한 충돌 및 화재해석 및 방호설계 등 관련 연구분야의 기초자료가 될 것이라고 판단되는 바이다.

배경: Fogarty 카테터는 원위부 동맥 색전을 제거하기 위하여 고안되었으며 1960년대 이래로 급성혈전색전의 치료에 획기적인 치료법이 되었다. 그러나 지난 30년동안 동맥폐쇄의 주원인이 심장에서 비롯하는 색전으로부터 죽상동맥경화증으로 변화하였으며 이런 맥락에서 단순 Fogarty 혈전색전제거술이 여전히 효과가 있는지 의문점이 생긴다. 대상 및 방법: 1990년 3월부터 2008년 8월까지 본원에서 Fogarty 혈전제거술을 시행한 156명을 대상으로 하였다. 환자를 혈전제거술만 시행한 79명(제 1 군)과 혈관우회수술을 같이 시행한 77명(제 2 군)으로 나누어 증상의 기간, 혈전의 원인, 응급실 내원 여부, 한방치료 및 오진경험, 동반질환, 주발생부위, 사망원인 등을 후향적으로 T 검증, 교차분석, 카이제곱 및 Kaplan-Meier을 이용하여 비교분석 비교하였다. 결과: 두군 모두 환자의 나이는 평균 64$\pm$10세로 비슷하였다. 제1군과 2군의 다리 통증 기간은 평균 12$\pm$4일 vs 71$\pm$14일(p=0.001), 응급실 내원한 경우는 50명(63%) vs 18명(23%) (p=0.005), 디스크로 오인하여 치료를 받거나 침을 맞은 경우가 20명(25%) vs 30명(39%), 내원전 항응고제 치료 받은 경우는 22명(28%) vs 11명(14%), 혈전원인은 심장질환 24명(30%) vs 6명(8%) (p=0.001), 동맥경화증 46예(58%) vs 67명(87%) (p=0.001), 외상 9명(11%) vs 6명(8%)이었다. 동반질환으로는 뇌졸증, 고혈압 당뇨가 주를 이루었으며(22$\sim$37%), 막힌 부위는 대부분 장골 및 대퇴동맥이었다 우회수술은 58명(75%)에서 대퇴-대퇴 및 대퇴-슬와동맥간 우회수술을 시행했다. 내막절제술은 각각 7명(9%) vs 18명(23%)에서 동반시술이 이루어졌다(p=0.012). 수술의 성공율은 27명(34%) vs 40명(52%) (p=0.019), 다시 막힌 경우는 37명(47%) vs 20명(26%) (p=0.000), 하지절단 4명(5%) vs 12명(16%) (p=0.012), 사망 10명(13%) vs 3명(4%) (p=0.044)으로 의의있는 차이를 보였다. 결론: 최근 급성동맥폐쇄증의 원인이 류마티스 심장질환에서 동맥경화성 질환으로 변화함으로서 단순한 Fogarty 혈전색전 제거술의 효과가 줄어들고 있어 이러한 단순 시술 대신에 부가적인 우회수술법이 고려되어야 할 것이다.

과학기술의 발전과 더불어 보건의료분야는 괄목할 성장을 가져왔고 국민생활 수준의 향상과 건강에 대한 관심이 고조됨에 따라 의료서비스의 수요가 급증하고 있다. 이 과정에서 국민의 권리의식의 신장, 의료행위의 본질에 대한 이해부족, 의료기술에 대한 지나친 기대, 상업화된 의료공급체계, 의사의 윤리의식 저하 및 의료법리에 대한 무지 그리고 사회적 불신풍조의 만연, 분쟁해결을 위한 제도적 장치의 결여 등이 요인으로 작용하여 의료사고 및 분쟁이 급증하는 추세이다. 본 연구는 치과관련 단체에서 보유하고 있는 소송과 관련된 자료 및 연세대학교 치과대학병원 구강내과에서 신체감정을 시행한 재판기록을 중심으로 하여 판결전문을 확보할 수 있는 치과 의료사고 판례 중 1994년부터 2004년까지의 민사소송 30례의 판례를 분석하여 다음과 같은 결과를 얻었다. 1. 소송의 연도별 분포에서 2000년 이후 급증하는 추세를 보였다. 2. 소송의 유형별 분포에서 발치와 관련된 소송이 전체의 36.7% 이었다. 3. 소송의 원인을 분석한 결과 불편감, 치료불만족과 관련된 것이 전체의 36.7%, 사망 및 영구손상이 각각 16.7% 이었다. 4. 원고의 소송결과 승소 및 강제조정, 화해권고결정이 60.0% 이었다. 5. 소송에 관련된 병원유형은 치과의원이 60.0%로 가장 높게 나타났다. 6. 소송의 심급별 구성비율에서 2,3심 이상 진행된 경우가 전체의 30.0% 이었다. 7. 손해배상 청구금액은 5천만원 이상 1억원 미만이 36.7%, 1억원 이상이 13.3% 이었고 손해배상 판결금액은 1천만원 이상 3천만원 미만이 40.0%, 1억원 이상이 6.7% 이었다. 8. 소송과 관련된 치과의사수는 2명 이상이 26.7%이었다. 9. 판결까지의 소요기간은 11개월에서 20개월이 46.7%, 21개월에서 30개월이 36.7% 이었다. 10. 의료과실 유무에서는 과실을 판정한 경우가 46.7% 이었고 소송과정에서 신체감정이나 사실조회가 이루어진 경우는 70.0% 이었다. 11. 의사패소 판례(18건)에서 판결의 주안점은 주의의무위반이 72.2% 이었고, 설명의무위반이 16.7% 이었다. 치과 의료분쟁의 경우 치료의 긴급성이 상대적으로 적어 의사의 설명의무 중요성이 폭넓게 요구되며, 주관적인 치료 만족도가 중요시되는 분야이기 때문에 결국 분쟁을 줄이는 방법으로 기술적인 과실도 줄여야 하지만 치과의사와 환자와의 신뢰 관계를 개선하는 것과 의사집단의 자율성(autonomy)의 회복이 중요하다. 그리고 불합리하게 시행되고 있는 의료배상책임보험의 보완과 함께 치과의사단체와 학계가 주도하는 교육 및 의료분쟁시 자문을 구할 수 있는 체계의 확립으로 의료분쟁에 대한 대처가 이루어져야 할 것이다.
