On the occasion of sudden cardiac fibrillation, it is critical to use the defibrillator which delivers electrical energy across the patient's chest, in short time. Since the capacitor and battery inside 1CD(implantable cardioverter/defibrillator) degrade according to the increase of usage and time, the charging time of capacitor becomes prolonged, in order to compensate the prolonged charging time, we propose an algorithm which controls the charging time by changing frequency and duty cycle of feeding pulses to the input of flyback converter.

Korea once was an endemic area for malaria. Of late in Korea malaria has been a rare disease, however, frequent foreign travel of Koreans to Africa, southeast and mideast Asia brought Korean physicians to see the patients with malaria once in a while. We encountered an imported malaria case (P. vivax) in a 39 year-old Korean male laborer working in Ivorycoast who was told to have malaria two years ago. He was treated with chlorquine but fever persisted. The Management with quinine, tetracycline was successful and recently he gets along well with after 6 months of follow-up.

본 논문은 발달장애유아 언어행동발달 컨텐츠 개발에 요구되는 기초연구로써 연구의 이론적 바탕을 확립하고자 하였다. 연구에 사용된 방법은 문헌조사 방법 및 현장 인터뷰기법을 병행하였다. 본 연구의 주된 목적은 크게 3가지로 구분된다. 첫째, 발달장애유아의 가정 내 교육 욕구를 분석하고자 하였다. 둘째, 발달장애유아의 언어발달 양상을 검토하고자 하였다. 세 번째 목적은 유아의 언어행동발달 컨텐츠 구성의 주요 지침을 설정하고자 하였다. 이상의 연구목적에 따른 연구결과를 요약하면 다음 몇 가지로 제시된다. 1.가정 내 부모-유아간 관계형성이 우선 고려 되어야하고, 이에 따른 상호작용은 발달적 애착형성이 가능한 방향으로 정립되어야한다. 2.발달장애유아의 언어행동발달양상을 검토한 결과에 따르면, Piaget는 언어행동발달에 있어 감각운동기적 환경탐색 기능을 강조하고 있고, 이는 현재까지 중요한 유아 발달의 기저로 정착되었다. 따라서, 발달장애유아의 언어행동발달을 위한 컨텐츠 개발 내용에 있어서도 이러한 기저에 충실함이 합리적이다. 3.발달장애유아들에게는 언어행동 양상의 갈래가 크게 운동장애 및 감각결함으로 나누어질 수 있으므로, 이 두 가지 갈래의 각기 다른 특성이 컨텐츠 구성에서 충분히 고려되어야한다. 4.자폐성과 같은 중증 전반적 발달장애 유아를 위한 언어행동발달 컨텐츠 구성에서 특히 고려해야 할 두 가지 요소는 모방행동기능과 반복단순훈련기능 향상으로 결론지을 수 있다. This article planed to establish the theoretical foundations of the research as a basic study needed for developing the contents of verbal(language) behavior development for the infants with developmental disabilities. The methods used in the study was previous literature researches and interviews with subjects. The purposes of the study were divided into three parts. First, it was to analyze the educational needs of the infants with developmental disabilities in home settings. Second, it was to review and discover the language patterns of the infants with developmental disabilities. The third purpose was to devise the major guidelines of their language development's contents. The results of the study were described as the followings. 1.The relationships between the infants with developmental disabilities and their parents and their interactions should move to build the developmental attachments between them. 2.According to the literature findings of their language development patterns, Piaget concentrated on the functions of sensory motor environmental exploring in the language behavior development. The functions have been settled down into the important foundation for the infants' development. Thus, it was resonable that the content's development of the language behaviors for the infants with developmental disabilities should based on the function addressed by Piaget. 3.The language behaviors' patterns of the infants with developmental disabilities generally were classified into motor disabilities and sensory defect(deficiency). Therefore, the two factors should be considered for the constructions of the contents. 4.Constructing the contents of the language behavior developments for the infants with severely pervasive developmental disabilities such as autism, the improvements of two functions, imitative behavior and repetitive simple training should be considered.

The purpose of this research is to analyze empirically the Equality between both sexes in Korean Bureaucracy. According to the result the masculine government employee think the feminine government employees has the professionalism in public organization and participating they endeavor devotedly to perform organizational aim. Also the trust feeling and cohesive force as the colleague were high. Only the external environment to a feminine special treatment policy is receiving political influence, for the masculine government employee still does not sympathize was remaining the possibility of knowing was homework. The inconvenience point is this paper does not investigate the feminine government employee. But The possibility of knowing the fact that is not only the masculine biased bureaucratic culture where the right consciousness and self realization craving of the woman are not displayed well it was.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Purpose : This study is conducted to evaluate the clinical success of secondary alveolar bone grafting using autogenous iliac particulate cancellous bone marrow in cleft maxilla. Materials and methods : We evaluated 107 cleft patients who had been admitted to the Dept. of Oral and Maxillofacial Surgery of Pusan National University Hospital from January 1, 1991 to January 31, 1999 and had been performed secondary alveola bone grafting with autogenous particulated cancellous bone marrow from iliac crest. Results : 1. Men were 70 and women were 37, which shows 65.4% and 34.6% and the proportion of males to females was 1.9: 1. Unilateral cases were 89(83.2%) and bilateral cases were 18(16.8%). 2, Age of bone grafting is widely distributed from 7 to 29, and the average was 13.2. 3. Success rate was 97.8% in unilateral cases, 94.4% in bilateral cases. Overall success rate was 96.7%. 4. We evaluated the bone graft contour by the percentage of bone attachment level adjacent to the alveolar cleft and the menial side showed 82.4% and the distal 87.7%. 5. The amount of notching the alveolar ridge at the grafted site through the ratio of notching length up to the most apical base to the length of proximal segment anatomic root was 0.19.

Deep vein thrombosis is recognized as a common complication in surgical patients in western countries especially in patients with high risk factors. The purposes of this study were to detect leg DVTs in early postoperative period by non-invasive surveillance and to analyze the risk factors of DVT. One hundred seventy one patients who underwent major operations(67 curative resection of colorectal cancer, 64 total hip replacement, 38 femur operation for fracture, and 2 colon resections for benign colon disease) were included for the prospective surveillance of leg DVT within 2 weeks after the operations. For the surveillance of leg DVT, strain gauge plethysmography(SPG) and Duplex scanning of both legs were completed for all patients except 10 patients. These 10 patients were examined in only one leg. The patients with past history of leg DVT or under prophylactic anticoagulant therapy were excluded from this study. To determine the risk factors related with leg DVT formation, age and sex of the patients, indication of surgery or surgical procedures, duration of operation, position during the operation, duration of postoperative immobilization, and preoperative serum level of antithrombin III (AT- III) were analyzed using Chi-square test. After performing SPG of 342 legs, 38 legs, showed abnormal on venous outflow/venous capacitance discriminant line chart, and 13 legs of 12 patients showed the finding(s) suggesting DVT on duplex scanning. Among the patients with abnormal duplex findings, 7 limbs(53.8%) were symptomatic, but the remaining 6 legs were silent. In 6 (15.8%) patients of 36 femur operations, 3(4.7%) of 64 total hip replacements and 3(4.5%) of 67 curative resections of colorectal cancer developed DVT by duplex scanning in the iliac(5), femoral-popliteal(6), and isolated calf(2) veins. After analyzing the risk factors, we could not find any statistically significant(p<0.05) factor related with leg DVT.

연구목적: 정신분열병 환자의 사회적응 정도를 측정하는데 사용되는 사회적응 척도의 한국어판을 개발하기 위함이다. 방 법: 사회적응 척도를 번역한 후 정신분열병 환자 67명과 정상인 78명을 대상으로 신뢰도와 타당도를 검증하였다. 결 과: 자료분석 결과 검사-재검사 신뢰도는 0.85, 검사자간 신뢰도는 0.89, 내적 일치도는 0.87로 높은 수치였다. 변별 타당도를 검증하기 위하여 정신분열병 환자군과 정상 대조군을 비교한 결과 정신분열병 환자군에서 사회적응 정도가 유의하게 낮았다. 구성 타당도를 알아보기 위하여 10개 영역간의 상관관계를 측정한 결과 성적적응 영역을 제외한 모든 영역들에서 유의한 상관관계를 보였다. 본 척도의 전반적 평가 영역 결과와 GAF 결과간의 상관성을 통해 간접적으로 검증한 공존 타당도 역시 유의하였다. 결 론: 한국판 사회적응 척도는 우수한 신뢰도와 타당도가 입증되었고 나아가 정신분열병 환자의 사회적응 정도를 평가하는데 유용하게 사용되어질 수 있을 것이다. Objectives: The purpose of this study was to develop the Korean version of the Social Adjustment Scale Ⅱ-Revised Version(KSAS Ⅱ-RV) in the schizophrenics. Methods: KSAS Ⅱ-RV was administered to 67 schizophrenic patients and 78 matched normal controls for examining the reliability and validity. Results: Data analysis showed statistically significant reliabilities and validities of KSAS Ⅱ-RV. The test-retest reliability, inter-rater reliability, and internal consistency for total scores of KSAS Ⅱ-RV were 0.85, 0.89. and 0.87, respectively. Evidence for discriminant validity of KSAS Ⅱ-RV comes from the results that the mean scores of schizophrenic patients were significantly high than those of normal controls. Construct validity was assessed by calculating the 10 inter-subareas correlations of the KSAS Ⅱ-RV, and all except the sexual adjustment area were statistically significant. Significant correlations between the global area scores of KSAS Ⅱ-RV and those of Global Assessment of Functioning Scale lend support for the concurrent validity of this instrument indirectly. Conclusions: KSAS Ⅱ-RV was found to be a valid and reliable instrument which can be used to evaluate the degree of social adjustment in the schizophrenic patients.

구순구개열환자에서 자기늑골을 이용한 일차성 골이식

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 years of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth. We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.
