In the treatment of dentofacial deformities, analysis of skeletal pattern, with evaluation of plaster dental case, is essential procedure. This study was based on 20 patients with dentofacial deformity who were admitted to the department of oral and maxillofacial surgery Kngnam sacred heart Hospital during the period of Jan 1989. We studied serial cephalometric radiogarphs of patients (pre-op, postop immediately, postop 6 moth). The obtained results indicates the good resistance of rigid fixation against relapse in orthognathic surgery.

The purpose of this study was to eximine the mechanisms of self-regulation techniques and improvement of sport performance. First of all, In this study, It was expressed mechanisms of psychological self-regulation techniques sometimes regarded as mental practice or biofeedback to aid better understanding as to how these skills would produce performance improvement. Also, The psychological skill training can be successfully controlled through systematic mental skill training. The focus of mental skill training is to perform consistently to athlete's potential. The current study reviewed literature on mental skills which are essential in consistent sport performance. Most of mental training programs are self-instructional and convenient to use. Through many sport psychologist's studies, psychological self-regulation was demonstrated its effect on performance in sport fields. Also, The effectiveness of psychological self-regulation has been verified by performance tasks and methods. Accordingly, As using psychological self-regulation and mental training, it will be applied to some kinds of sport performance. Finally, Future directions for study in psychological self-regulation and mental training are required for systematic and scientific training program.

In the system using one sensor, to describe accurate situation or conclude from information of one source in difficult. Moreover, sensor noise degrades the belief of decision. Multisensor information system, however, can increase the belief of date by imploying more than one source of information simultaneously. Another advantage of the system is that it can accomplish its task with other sources of information when one source malfunctions. In this paper, we implemented data association methods to identity moving flight targets using distance, probability theory, Dempster-Shafter theory for the low level process in the information fusion system. Data association is to classify information from various sources into data groups depending for the same flight object. Times and errors of these data association methods are analyzed.

연구목적 : 본 연구는 국내 노인의 습관을 조사하고 불면 증상과 연관 있는 인구학적, 질병학적 요인을 알고자 했다. 방 법 : 1997년 12월부터 1998년 1월까지 약 1개월에 걸쳐 2단계 층화집락표본추출의 역학조사법을 통해 선정된 3개 4개동 거주의 만 65세 이상 노인을 대상으로 수행되었다. 대상자 중 723명에서 등답을 받았으며 응답률은 73.8였다. 대학생인 설문조사요원들을 훈련시킨 뒤, 이들로 하여금 대상지역의 노인거주가정을 방문하여 개개 노인을 대상으로 반구조화된 면담으로 수면습관 및 불면증상 설문을 실시하였으며 그 외 한국어판 노인정신장애평가척도, 삶의 질 척도를 이용한 설문조사와 과거 질병력을 청취조사하게 하였다. 결 과 : 국내 노인들은 평균 오후 10시 16분에 자리에 누워 오전 5시22분에 일어나서 총 7시간 6분의 수면시간을 보였다. 노인의 11.7%가 거의 매일 밤 불면증을 14.8%가 간헐적 불면증을 호소하였다. 남자에서는 연령이 증가할수록 침상에 누워있는 시간이 증가하고, 또, 입면시까지 소요되는 시간과 수면 중의 각성회수가 증가되었으나 여성에서는 명확하지 않았다. 단변수 분석에서 요통, 중풍 병력의 환자에서 불면증상이 심했다. 다변량분석 결과 불면 증상과 관련 깊은 요인으로 남자에게서는 고령과 우울증상이 여자에게서는 남자의 위험요인에다 신체통증과 피부병력이 추가로 관련이 있었다. 결 론 : 지역 거주 노인에서 불면 증상은 매우 흔한 증상이며 우울증상과 명확한 상관관계를 보이고 있었다. 불면증을 극복하기 위해 불면증 위험요인의 인과관계에 대한 추후 연구가 필요하다. Objectives : The purpose of this study is to analyze sleep habit and investigate the association between insomnia and demographic, health and psycho-behavioral symptomatology in Korean urban elderly Method : A total of 723 community residents aged 65 years or older were surveyed by two stage, random cluster sampling method. The response rate was 76.2%. Interviewers performed door to door visits and administered a questionnaire about sleep, past medical history, and several scales as the Psychogeriatric Assessment Scale(PAS), the short form Quality of Life Scale (SF-36) and etc. Results : The mean scores are as follows : retiring time was ten-sixteen p.m., wake-up time was five twenty two a.m., duration of sleep was seven hours and six minutes. Among the elderly, 11.6% and 14.8% of the subjects reported chronic and intermittent difficulty in sleeping, respectively. The patients with back pain and history of stroke complained of more insomnia symptoms in univariate analysis. In ANCOVA analysis, insomnia symptoms were associated with an old age, depressive symptoms in male. Bodily pain and history of dermatologic disease were additional risk factors in female. Conclusions : The data suggest insomnia is one of most common health problems among elderly Koreans living in the community. Strong positive relationship between depressive symptoms and insomnia were found. Further research is needed to explore the causal relationship between insomnia and risk factors.

Medicinal Precipitated Clacium Carbonate is prepared by the interaction of Calcium Chloride and Ammonium Carbonate Solutions in this study. It has been known that the particle size of Precipitated Calcium Carbonate is greatly affected by the concentration, temperature, and moli-ratio of reactant solutions as well as the temperature at which the precipitate is dried and the temperature of washing water. The purpose of this study is to determine the optimum preparation Condition of medicinal Precipitated Calcium Carbonate. A randomized complete block design wuggested by G.E.P. Box and K.B.Wilson was for this purpose. The optimum preparation condition of light and fine precipitated Calcium Carbonate obtained from this study is as follows : 1) The reacting temperature range is 25∼45℃ 2) The concentration range of reactant solutions is 10∼30% 3) The optimum mole-ratio (CaCl/(NH) CO) is 1.0∼2.0. 4) The drying temperature range is 60∼80℃. 5) Temperature range of washing water is 25∼60℃.

국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.

LOWER ARM which jointed Independent Front Suspension is resulted in stress sidtribution analysis by using Finite Element Method. These datas represented in the condition of 8 loads and 3-type-section(I, H and H+I) type. On the basis of it, it is optimized shape and dimension fo LOWER ARM. The optimized performance shows that the H type of 3 types has an available strength and H´ section, which proved by H type, finds safety factor and yield strength in each case of load condition.
