목적 : 항균제 오남용으로 인한 내성균의 출현, 약물부작용의 발생 및 약제 비용의 증가는 환자 개인뿐만 아니라 사회적으로 문제가 되고 있다. 본 연구는 항생제의 오남용을 막기 위한 제도의 일환으로 시행한 아미노글리코사이드 사용 제한정책의 비용 효과적인 측면을 조사하고 그람음성간균에 의해 병원성 균혈증이 발생한 환자들을 대상으로 이 정책이 항생제 내성률과 환자 사망률에 미치는 영향을 연구하였다. 방법 : 930병상 규모의 3차 병원인 일개 대학병원에서 아미노글리코사이드 사용제한정책이 시행된 직후인 2002년 3월에서 9월 사이에 그람음성간균(Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, Serratia marcescens, Stenotrophomonas maltophilia, Burkholderia cepacia)에 의해 발생한 병원성 균혈증 환자 60명(실험군)과, 이 정책이 시행되기 전에 입원한 환자들 중 균주별로 같은 수만큼 선별한 병원성 균혈증 환자 60명(대조군)의 의무기록을 후향적으로 조사하였다. 결과 : 아미노글리코사이드 사용제한정책이 시행된 시기인 2002년 3월에서 9월 사이에 처방된 아미노글리코사이드 사용량 및 비용을 이 정책이 시행되기 전인 2001년 3월에서 9월 사이와 비교한 결과, 아미노글리코사이드의 사용량(antimicrobial utilization density)은 사용제한 후 225.2에서 130.3으로 42% 감소하였고 약제 비용은 44% 감소하였다. 아미노글리코사이드 사용제한 후 병원성 균혈증을 유발한 그람 음성간균의 이 항생제에 대한 내성률은 유의한 변화를 보이지 않았으며 균혈증과 직접 연관된 사망률도 환자의 나이, 성별, 기저질환 및 원발병소 등을 보정할 경우 유의한 차이를 보이지 않았다(40.4% vs. 24.1%, P=0.11). 결론 : 아미노글리코사이드를 5일을 초과한 사용 시 감염전문가의 사전 승인을 필요로 하는 사용제한정책은 아미노글리코사이드의 사용량과 비용을 유의하게 감소시켰다. 또한 이 정책 시행 후 그람음성간균에 의한 균혈증 환자에서 균혈증으로 인한 사망률과 아미노글리코사이드에 대한 내성률은 유의한 차이가 없었다. Objective : To evaluate the effects of an aminoglycoside restriction policy on expenditures for aminoglycosides, antimicrobial resistance rates and clinical outcome of nosocomial bacteremia caused by Gram-negative bacilli (GNB). Methods : Starting in February, 2002, a prior consultation with an infectious disease specialist for using aminoglycoside antibiotics over 5 days was required in a 930-bed university hospital. In retrospective analysis of medical records 7 months after initiation of the aminoglycoside restriction policy, sixty cases of clinically relevant nosocomial bacteremia caused by GNB were found. These bacteremic patients were compared with sixty, species-matched, control patients with nosocomial Gramnegative bacteremia before the policy for total expenditures for aminoglycosides, susceptibility to antibiotics and clinical outcomes of bacteremia. Results : During the same period of 7 months before and after the restriction policy, total expenditures for aminoglycosides decreased by 44% in cost (from 465,030,841 Won to 259,618,337 Won) and the antimicrobial utilization density of aminoglycosides decreased by 42% (from 225,2 to 130.3). On the other hand, the patterns of antibiotic susceptibility and bacteremia-related in-hospital mortality rates after the policy did not show a significant change, compared with those before the policy. Conclusion : Antibiotic restrictions are among the most popular methods to diminish the practice of antibiotic overuse in hospitals. In this study, requirement for prior approval of aminoglycoside use over 5 days led to a significant decrease in the amount and cost of total aminoglycosides without a significant change in susceptibility patterns and bacteremia-related mortality rates.

The purpose of this study was to determine the correlation between the awareness and the status of their won oral diseases. A questionnaire survey form was designed to determine the awareness of their won oral diseases and asked aoo of the university freshmen students to fill out the all of questionaries. They were then immediately examined for을 새 determine their status of dental hard tissures by using the WHO criteria. Also determined were the CPITN and the needs for orthodontic as well as prosthodontic treatments. The results were then statistically analyzed to determine the correlation coefficiencies between the awareness and the status of oral diseases by using SPSS statistical package. The results suggested the followings; 1. The correlation coefficiencies between the awareness and the status for number of teeth decayed, missed, and indicated for extractions were 0.18, 0.06 and 0.09 respectively. 2. The correlation coefficiency between the awareness and the status in treated teeth(F component) and CPITN were 0.622 and 0.10 respectively. 3. the agreement between examiners and examinees on the needs for prosthodontic treatments was 87.31% and their sensitivity and specificity were 47.54% and 88.55% respectively. 4. the agreement between examiners and examinees on the needs for orthodontic treatment was 70.40% and their sensitivity and specificity were 77.27% and 60.71% respectively. Data indicate that a majority of respondents are lacking in the awareness of their own oral disease status. Therefore, it is concluded that a regular oral examination, a regular counselling on oral health status as well as specific oral health education for each individual warranted.

This study has been aimed to analyze UCHIMATE technique of Judo gymnastically. The following are the results and the proposition obtained through an image analysis method 3 men half heavy weight champions of the national Judo standing team(85-95kg) were used as subjects for the study. 1. CONCLUSION The following are the conclusion obtained through the discussion of analysis results of the Uchimata technique using 3 men, half heavy weight(85-95kg) champions of the National standing Judo team. 1) The time performing total technique were 1.48-seconds which was performinglonger than the light heavy weight class of 1.28-seconds by 0.20-seconds, this showed that the heavy weight class players demonstrated the technique later than the light heavy weight class palyers. 2) The average length of moving 1-step leg for attacking was 24.27cm, and 2-step leg moving was 92.87cm on average. Therefore, the shorter the moving distance, the more the technique performing hour could be shortened. 3) In the hanging phase, the moving displacement of the center of gravity of the body weight showed in horizontal, vertical, right and left direction 28.97cm, 21.59cm and 13.57cm respectively. Each of which were longer than the phase of KUZUSHI and TSUKURI. Such results show that the center of gravity of the body in move lift the opponent. This reducing the displacement of body weight from the center toward the right and left direction in the phase of KAKE is considered to be effective in demonstrationg the technique. 4)The central speed of the body was 0.8cm per second on average and the average vertical speed was 0.74cm per second. The speed of right and left movement was 0.51cm per second on average which showed the horizontal speed was the fastest while it is preferred that the vertical speed should be faster than that of the horizontal. 5) Angle of the Trunk showed 98.13 ˚ on average in the hanging phase and the larger the trunk angle, the shorter the needed time to demonstrate the technique, thus making the throw of the opponent over shoulder more advantageous. 2. PROPOSTION The following propositions are suggested through this analysis for further study : 1) It is to be considered that the kinetics in hanging the thigh and the degree of every segment of the body be studied in a more detailed fashion. 2) A study on the technique of thigh hanging in an actual game situation (rather than during mere exercises) is necessary. 3) It is necessary to study the TORI and UKE techniques together. 4) The study of each weight class ought to be performed.
