본 연구의 목적은 노인 보건의료공급의 활성화 방안에 있어 노인보건이나 요양원에 관한 선행연구는 많이 제시되고 있으나 노인병원에 관한 고찰은 많이 수행되고 있지 않다. 따라서 노인의료 공급 활성화 방안의 일환으로서 노인병원의 필요성과 노인병원제도 도입의 제문제점을 살펴 노인의료공급의 활성화 방안을 제시하는 것이다. 이에 현재 한국 노인의 의료이용현황, 노인병동 운영실태, 노인 의료비동향 등을 고찰해 보고 일본 등 외국 실태를 분석하여 현 노인의료체계의 제문제점, 가족의 부양부담, 민간 부분의 노인병원개설 기피현상을 제시해 봄으로 한국의 노인 병원제도 도입방안을 모색해 보는 것이다. The health affairs among various problems of the aged are main concerns of the elderly. Without the integrated health-welfare policy for them in comparision of the aging degrees in advanced country, the elderly health problems seem to get worse in Korea. The purpose of this study is to suggest the better development of health and medical services for the elder in Korea. The problems of the system of supply medical services for the elder in Korea are needed more develop, preventive and productive health policies and programs nowdays, hence, this study also described currently problems of medical care for elders. With comparing system of medical support among other countries, let us know the need of several system of medical care for the elders. Especially to cure and care for the elders chronic diseases and support burden for caring caregives, we need mare variable facilities such as intensive nursing home and hospital for the elders. Hence, this paper emphasized the need of health policies which mode manifest through administrative actions such as make law "health care and medical services" specially program for medical insurance for the elders.

Objectives Hand paresthesia is common syndrome and the cause is more unknown than known reason. The Purpose of this study were investigated the effects of Myofacial Pain Syndrome theory to make diagnosis and treatment by Pharmacopuncture for the patients of hand paresthesia. Method This study was carried out to established the clinical criteria of hand parethesia. The patients who had past history of diabeics, neuropathy induced by alcohol or drug were excluded, and 86 patients who had hand paresthesia related with unknown-reason was selected by the interview process. And the effects of Pharmacopuncture theory were analyzed using VAS score before and after treatment. Results and conclusions 56.9% of unknown-reason patients are positive at diagnosis by MPS theory. While positive group decrease from $62.81{\pm}14.27$ to $25.28{\pm}15.97$, negative group decrease from $55.88{\pm}10.92$ to $48.28{\pm}14.01$ by VAS scores. Positive group was accordingly more effective than negative group. So diagnosis and treatment for hand numbness patients by MPS theory was useful in clinical.

Backgrounds/Aims: Hepatitis B virus (HBV) infection and chronic alcoholism are major risk factors for chronic liver disease in Korea. Methods: We investigated the prevalence of occult HBV infection in 198 non-alcoholic (group I) and 85 chronic alcoholic subjects (group II), none of whom showed the hepatitis B surface antigen (HBsAg). Among chronic alcoholics, 25 patients showed cirrhosis. Using serum samples stored at -70℃, liver enzymes, anti-Hbs, and IgG anti-HBc were measured via EIA and serum HBV DNA was quantified via real time PCR. Results: IgG anti-HBc seropositivity, an indicator of past infection, was higher in group II (64.7%) than in group I (43.4%; p<0.01). Eleven of 283 patients (3.2%) were seropositive for HBV DNA, indicating occult infection, but this value did not differ between groups (group I: 3.5%, 7/198; group II: 4.7%, 4/85; p=0.64). In group II, HBV DNA seropositivity was higher in cirrhotic patients (12%, 3/25) than in non-cirrhotic alcoholic liver disease (1.7%, 1/60; p=0.074). Conclusions: Past HBV infection was more prevalent in alcoholics than non-alcoholics, but the prevalence of occult HBV infection did not differ between groups. However, alcoholics with cirrhosis tended to show a higher prevalence of occult HBV infection. (Korean J Med 75:539-545, 2008)

웨이브렛 계수의 제로트리를 이용한 유효계수 예측 알고리즘
오성남(Sung-Nam Oh),김용선(Yong-Sun Kim),전용억(Yong-uk Chun),한성우(Sung-Woo Han),전병민(Byung-Min Chun) 한국정보과학회 1996 한국정보과학회 학술발표논문집 Vol.23 No.1A
제로트리에서 무효계수의 예측은 제로트리루트를 판단하기위해 현재계수의 하위계수를 모두 탐색해야 하며, 현재계수가 무효계수의 하위 무효계수인지를 판단하기 위해 상위계수 이하의 모든계수를 탐색해야 한다. 이러한 문제점을 제거하기 위해 전처리에서 모든 무효계수를 예측하고, 2*2으 블록을 만들어 바로위의 계수만을 검색하여 무효계수 여부를 판별할 수 있으며 복원의 시간을 줄일 수 있는 방법을 제시한다. 또한 임베디드 제로트리에서는 예측에 의해 만들어진 심볼과 연속근사양자화 한 추가정보를 전송하여야하며, 일반적인 압축방법에서는 DC 성분은 예측 코딩하여 그대로 전송하고, 그밖의 정보는 양자화를 적용하여 전송한다. 그러나 제안한 알고리즘에서는 하나의 스트림만을 전송하여 재구성 시간을 줄일 수 있으며 단순 스칼라 양자화를 사용함으로써 코딩에 소요되는 시간을 단축한다.

볼빔 시스템에 대한 입자 군집 최적화를 이용한 최적 퍼지 직렬형 제어기 설계
張漢鍾(Han-Jong Jang),吳聖權(Sung-Kwun Oh) 대한전기학회 2008 전기학회논문지 Vol.57 No.12
In this study, we introduce the design methodology of an optimized fuzzy cascade controller with the aid of particle swarm optimization(PSO) for ball & beam system. The ball & beam system consists of servo motor, beam and ball, and remains mutually connected in line in itself. The ball & beam system determines the position of ball through the control of a servo motor. We introduce the fuzzy cascade controller scheme which consists of the outer(1st) controller and the inner(2nd) controller as two cascaded fuzzy controllers, and auto-tune the control parameters(scaling facrors) of each fuzzy controller using PSO. For a detailed comparative analysis from the viewpoint of the performance results and the design methodology, the proposed method for the ball & beam system which is realized by the fuzzy cascade controller based on PSO, is presented in comparison with the conventional PD cascade controller based on serial genetic alogritms.

Objectives : Since vertebroplasty has been introduced, we performed short segment pedicle screw fixation with augmented intra-operative vertebroplasty in patients with unstable thoraco-lumbar fracture. Our intentions are to demonstrate the efficacy and indication of this new technique compare to conventional methods. Material and Methods : The surgery comprised of pedicle screw fixations on one level above and below the fracture site, and the fractured level itself, if pedicle is intact, and intra-operative vertebroplasty under the fluoroscopic guide with in-situ postero-lateral bone graft. Also, in cases of bone apposition, we removed those with small impactor through a transfascetal route. During the last 2 years, we performed in seven(7) unstable thoraco-lumbar fracture patients who consisted of two different characteristics, those four(4) with primary or secondary osteoporosis and three(3) of young and very healthy. All patients were followed clinically by A.S.I.A. score and radiography. Results : Mean follow up period was 14 months. We observed well decompressed state via transfascetal route in cases of bone fragments apposition and no hardware pullout in osteoporotic cases, no poly-methyl-methacrylate (PMMA) leakage through the fracture sites into the spinal canal, and no kyphotic deformities in both cases during follow-up periods. All patients demonstrated solid bony fusion except one following osteoporotic compression fracture on other sites. Conclusions : In the management of unstable thoraco-lumbar fracture, we believe that this short segment pedicle screw fixation with augmented intra-operative vertebroplasty reduce the total length or levels of pedicle screw fixation without post-operative kyphotic deformity.

Gangliogliomas are benign tumors, composed of neoplastic astrocytes and nerve cells. They are rare, account for 0.4-6.25% of all primary central nervous system neoplasms. Gangliogliomas affect predominantly infants or young adults. Gangliogliomas are preferentially encountered supratentorially, predominantly affecting the temporal lobe. Spinal gangliogliomas affect predominantly the cervical spinal cord. We report a case of cervical ganglioglioma which was successfully removed surgically, with a review of literature.

최적 Interval Type-2 퍼지 제어기 설계 및 응용
장한종(Han-Jong Jang),오성권(Sung-Kwun Oh) 대한전기학회 2009 전기학회논문지 Vol.58 No.8
In this study, we introduce the design methodology of an optimized Interval Type-2 fuzzy controller. The fixed MF design of type-1 based FLC leads to the difficulty of rule-based control design for representing the linguistically uncertain expression. In the Type-2 FLC as the expanded type of Type-1 FLC, we can effectively improve the control characteristic by using the footprint of uncertainty(FOU) of membership function. Type-2 FLC has a robust characteristic in the unknown system with unspecific noise when compared with Type-1 FLC. Through computer simulation as well as practical experiment, we compare their performance by applying both the optimized Type-1 and Type-2 fuzzy cascade controllers to ball and beam system. To evaluate each controller performance, we consider controller characteristic parameters such as maximum overshoot, delay time, rise time, settling time and steady-state error.
