Objectives : The purpose of this study was to analyze the effect of outpatient cost sharing reduction on health care utilization of children under 6 years old. Methods : The data in this analysis was the health insurance claims data between August 2006 and July 2008. The study group was divided into two age groups, namely 0-5 years old and 6-10 years old. This study evaluated the impact of policy change on office visits per person and expenditure per visit. In order to do so, the double difference analysis is used. Results: The results showed that outpatient cost-sharing reduction has never really had a huge impact on office visits per person and expenditure per visit. Conclusions: This study showed that the outpatient cost sharing reduction for children under 6 years old policy is not working. Therefore, cost sharing of National Health Insurance by income class is needed.

본 30세 여환은 류마치스성 심장판막질환 진단하네 승모판막 및 대동맥판막 치환술 시행후 종격동염 발생하여 지속적 종격동 세척 및 3주간의 항생제 치료후 퇴원하였다. 외래 추적중 다시 감염 및 염증소견 보여 입원하여 혈액배양검사와 흉부전산화 단층촬영시행하였다. 검사상 종격동염의 이후 3주간의 항생제 치료에도 염증 소견이 지속되어 다시 시행한 흉부 전산화단층촬영상 상행대동맥에 거대 가성대동맥류소견보여 재개흉술을 시행하여 초저체온 완전 순환정지 하에 가성대동맥류를 절제한 후, 우심낭편을 이용하여 대동맥 성형술을 시행하였다. 수술후 환자는 순조롭게 회복하였으며 현재 외래에서 추적관리하고 있다.

외래에서 고막에 대한 간단한 수술을 시행함에 있어 고막의 국소 마취법으로 iontophoresis(전기 영동법)은 오래 전부터 널리 시행되어 왔으나 와우나 전정신경계에 대한 독성 때문에 논란의 대상이 되어 왔다. 1973년 Comeau이후 여러 학자에 의한 일련의 동물 및 인체 실험결과 lidocaine 의 iontophoresis는 안전하고 효과적인 방법으로 실제 임상에서의 사용을 권장하고 있으며 근년 널리 이용되고 있으나 iontophoresis를 시행함에 있어 기구 자체의 금속성 물질에 의한 독성 및 사용 약물의 내이 침투에 의한 영향에 관해서는 아직도 많은 연구가 진행되고 있다. 저자들은 1983년 부터 1986년 12월까지 고려병원 이비인후과에서 고막절개를 위해 iontophoresis에 의한 lidocaine의 국소마취법을 시행받은 환자중 무작위로 추출한 39명(46이)을 대상으로 iontophoresis시행 전후의 청력상의 변화에 관한 청각학적 고찰을 시행하여 iontophoresis후 청력 역치에 유의한 변화가 나타나지 않는다는 결과를 얻었다.

The office-based, un-sedated vocal fold injection laryngoplasty has re-emerged in the past decade as an appealing alternative to microsuspension laryngoscopic procedure which is conducted under general anesthesia. The trend toward vocal fold injection laryngoplasty in an in-office setting was possible due to technological evolution for visualization and new injection materials. However, invisibility of the injection needle has been the main shortcomings of cricothyroid approach. The purpose of this review is to provide an up-to-date review of office-based, trans-cricothyroid membrane approach injection laryngoplasty technique under local anesthesia and efforts made to increase the preciseness of amount and location of the injected materials in the management of glottic insufficiency. A review of variable efforts undertaken to maximize the result of cricothyroid approach by technically increasing accuracy of the location of needle tip was done. With the proper patient selection and utilization of the new technologies, office-based and un-sedated vocal fold injection laryngoplasty via cricothyroid approach can be redeem as a main-stay in the management of glottic insufficiency, such as vocal fold paralysis, vocal fold paresis, vocal fold atrophy and vocal fold scar.

Musculoskeletal ultrasound has unique advantages that may be free from exposure to radiation, low price compared to MRI, outpatient procedure that can be easily accessible, and better accuracy combined with physical examination. Dynamic ultrasound performed with stress tests are known to be useful for detecting the hidden lesions in the tendons, ligaments, nerves. Ultrasound in the elbow can be used easily in the outpatient for evaluation of the joint surface and synovial space; diagnosis for tendon diseases such as lateral epicondylitis, medial epicondylitis and morbidity of peripheral nerves; guide for anterior-posterior bursal and intra-articular injections.

Since the 1960s, the United States' (U.S.) deinstitutionalization policy has reinstated people with mental illness into communities. Unfortunately, when untreated, some people with psychiatric disorders become homeless, and some commit serious crimes during a psychological crisis. Assisted Outpatient Treatment (AOT), also known as Kendra's Law in New York and Laura's Law in California, provides treatment, services and support to people with mental illness in the community. AOT has repeatedly been found effective and is recognized as an evidence-based practice. The response to the mental health crisis (crisis intervention) in the U.S. has also been successful in preventing worsening mental illness and related criminality and other issues. This paper provides an opportunity to create a platform from which to learn how to successfully apply the AOT and crisis intervention of the U.S. to South Korea within the cultural and societal context when establishing social services for people with mental illness in South Korea's communities.

Edwards Duromedics mechanical valve was introduced into clinical use in 1982 and is still being used today after several modifications. Valve-related complications after mechanical valve replacement are thiombo-embolism, endocarditis, valve malfunction, valve leaflet escape and fracture. Incidence of valve leaflet escape is very low. A 40 year-old male patient who had undergone mitral replacement with a 31mm Edwards Duromedics mechanical valve(model

지속성 외래 복막투석은 말기 신부전 환자들에게 널리 시행하는 신 대체 요법으로, 복막투석 환자에게서 주된 합병증으로 일어나는 단백질-열량 영양실조를 치료하기 위하여 아미노산을 복강 내로 주입하는 치료방법이다. 이현석 등(2004)의 연구에서는 아미노산 복막 투석액(IPAA)이 영양실조 환자들에게 실제로 영양상태에 미치는 영향을 평가하기 위하여 지속성 외래 복막투석 환자 43명을 12개월 동안 3개월 주기로 관측하여 얻어낸 반복측정자료를 바탕으로 IPAA의 효과 여부에 따라 반응군과 비반응군을 분류하였다. 본 논문에서는 이러한 두 그룹을 효과적으로 분류할 수 있는 분류기준변수들을 찾아내고 이 분류기준변수의 값을 바탕으로 새로운 환자에게 IPAA의 투여 여부를 진단할 수 있는 여러 분류방법들을 고찰하여 비교 연구하였다. 모수적인 방법으로 선형판별분석, 이차판별분석 및 로지스틱 판별분석을 소개하고 비모수적인 방법으로 support vector machine(SVM)을 소개하여 분류분석의 결과를 비교하여 두 그룹을 최소한의 오류로 분류하는 방법을 제안하였다.
