목적 본 연구의 목적은 국내 정신의료기관(정신병원, 종합병원 정신과)에서 간편하게 사용할 수 있는 신뢰도와 타당도가 검증된 입원환자의 서비스 만족척도를 개발하기 위한 것이다. 방법 여러 단계를 거쳐 국내 실정에 맞는 문항을 개발하였고,정신병원, 종합병원, 대학병원 정신과 병동에서 퇴원하는 348명의 환자들을 대상으로 신뢰도와 타당도를 조사하였다. 요인분석 결과 5개의 요인이 추출되었으며 전체 변량의 63.04%를 설명하였다. 내적 일관성에 대한 신뢰도 계수 (Crohnbach's α)는 0.95로 상당히 높은 수준이었고, 수정된 개별문항-총점 상관계수는 0.50부터 0.72까지의 범위에 속하였다. 요인분석을 통해 추출된 서비스 만족척도의 각 하위척도 점수와 서비스 만족척도에 첨부된 각 영역에 대해 전반적인 만족도를 묻는 세 개의 문항 점수 간의 상관성 역시 유의하게 높았다. 결과 진단명에 따른 서비스 만족척도의 전체 점수에서는 불안/신체형/강박장애 환자군과 기분장애 환자군이 각각 정신분열병 및 기타 정신병 환자군과 알코올중독 장애 환자군에 비하여 유의하게 높은 점수를 보였으며, 입원형태에 있어서는 자발적 입원군이 강제 입원군에 비하여 전체 만족점수가 유의하게 높았다. 그러나 성별, 월수입, 학력, 직업, 종교, 결혼상태 등의 변수에서는 서비스 만족척도의 전체 점수에서 유의한 차이가 발견되지 않았으며, 마찬가지로 연령, 입원일수, 입원횟수, 첫 발병나이, 유병기간 등의 임상적 변수에서도 서비스 만족척도의 전체 점수와 유의한 관계를 보이지 않았다. 서비스 만족척도의 전체점수에서 대학병원 환자군이 정신병원 환자군과 종합병원 환자군에 비하여 각각 유의하게 높았다. 결론 결론적으로 국내 정신의료기관에 입원한 환자들의 서비스 만족을 평가하기 위한 목적으로 개발된 본 척도는 높은 수준의 신뢰도와 타당도를 보였으며, 또 국내 정신의료 환경에 맞는 요인구조를 보였다. 따라서 정신의료 서비스에 대한 정신과 환자의 만족도에 대한 연구가 거의 없는 실정에서 본 척도의 개발은 향후 국내 정신의료의 질과 치료결과를 높이는 도구로 활용될 수 있을 것으로 기대된다. Objectives : To develop and test the validity and reliability of a brief self-completed questionnaire (Service Satisfaction Scale : SSS) for routinely assessing the quality of service in psychiatric ward inpatients. Methods : A 30-item multidimensional questionnaire was developed by several steps of face validity and content validity. The questionnaire was administered to inpatients (n=348) discharged from psychiatric hospitals, general hospitals, and University hospitals. Construct validity was supported by performing principal component analysis. Reliability was estimated by calculating internal consistency of Cronbach's alpha. Results : Factor analysis yielded five factors comprising staff attitude, treatment quality, ward environment, access/cost, and ward rule, which account for 63.04% of the common variance. The internal consistency of the scale was high (Cronbach's alpha=0.95). The concurrent validity was supported by the significant correlation of each of five factors with item that measured overall satisfaction of SSS. Patients with neurosis (anxiety disorder, somatoform disorder, obsessive compulsive disorder) and mood disorders were significantly satisfied than those with psychosis and alcoholic disorders. Patients who admitted voluntarily were more significantly satisfied than those who admitted involuntarily. Sociodemographic variables such as age, gender, marital status, monthly income, education level, employment status and religion were not significantly different at the total scores of SSS. Similarly, clinical characteristics such as age of onset, duration of illness, lengths of hospital stay and number of previous hospitalization did not associate significantly with the total scores of SSS. Patients discharged from university hospitals were significantly more satisfied than those of the general and psychiatric hospitals. Conclusion : SSS performed well in the validity and reliability, indicating that it can be a useful tool for measuring Satisfaction of psychiatric inpatients in Korea.

The pandemic influenza (H1N1 2009) virus, after being introduced in Korea in April, 2009, spread rapidly nationwide in mid-2009. This study was conducted to characterize trend in age distribution of visitors to Flu-clinics during the pandemic. Demographic, clinical and laboratory data of visitors to flu clinic from Week 36 to 52 (August 30 to December 26) of 2009 were retrieved and collected from electronic databases at 9 hospitals. Visitors 0-6, 7-12, 13-18, 19-29, 30-64, and 65 years or more of age were classified into group I to VI, respectively. A total of 107,467 visitors were seen at Flu-clinics for a 17-week study period. Of those, 32,485 were laboratory-confirmed. Antivirals were prescribed for 62,533 visitors. Numbers of visits, prescriptions of antivirals, and laboratory-confirmed cases of the pandemic influenza (H1N1 2009) peaked at Week 44. A large number of visits by group II and III were followed by those of group I and V, especially around the peak. Numbers of visits by group VI were lowest in all hospitals. In some hospitals, higher number of visits lasted longer in children than in adults while vice versa in other hospitals depending on the location. In summary, the pandemic influenza (H1N1 2009) was presumed to peak in late October and involved majorly children and students in Korea. Unique age distribution of visitors to flu clinic was observed in some hospitals.

The forces and moments at the aircraft c.g. have components due to aerodynamic sffects and to engine thrust. For the flight stability and autopilot systems we present a attitude control method using an intelligent control algorithm Which is based on the control rules from experts knowledge concerning the motion equations and other experiences. Then a robust fuzzy cintroller is developed to control the flight attitude. The controller can deal with multiple inputs and outputs. We have made an aircraft model and the orientation sensor for experimental fights. The control rules based on the flight expert's experience and knowledge can be programmed by fuzzy rules, and determined control rules by experimental flight. We can be stable attiude control by fuzzy controller.

2자유도 PID 제어기의 파라미터 α 추종을 이용한 2관성 시스템의 진동억제

추연규,김현덕 진주산업대학교 2004 論文集 Vol.43 No.-

A torque transmission system composed of several gears and couplings is flexible. In order to get an exact response of motor, the torsional vibration due to an unexpected change of motor speed must be suppressed. Therefore, it is very important that motor control suppress vibration. Various methods to control it including dual inertia system are proposed. Specially, the method of vibration suppression is that vibration can be suppressed to feedback the estimated torsion torque via the disturbance observer filter being of normal filter. The suitable Proportional controller and coefficient parameter can be designed using CDM and the torsional vibration also be suppressed, but it has a low degree of adaptability to disturbance. The PID controller can be designed easily, but makes the excessive overshoot and oscillation for system response in the early period. To resolve these problems, simple and practical PID controller with two degree of freedom is proposed recently that it can improve performance of obeying the reference unconcerned in any disturbance by changing the proportional gain by two degree of freedom parameter. But it has also the defect that parameter α must be changed to obtain the ideal Proportional parameter. On this paper, we design the controller which automatically adjusts parameter α using Fuzzy Algorithm to overcome such defects.Also, we compare the proposed method with established one and evaluate them to confirm performance of the designed controller.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.
