Local injections of botulinum toxin A have been reported in the treatment of neurogenic bladder dysfunctions including detrusor sphincter dyssynergia and detrusor overactivity. We reports a case of intradetrusor injection of botulinum toxin type A in acervical cord injured patient with neurogenic overactive detrusor refractory to high dose anticholinergic medication. Botulinum toxin A (200 units) was injected cystoscopically into the detrusor in 40 sites over the bladder with sparing the trigone. Urodynamic studies were performed at baseline, and eight days, four weeks, and eight weeks after intradetrusor injection. There was marked improvement of the urodynamic parameters including maximum cystometric capacity and maximum detrusor pressure after intradetrusor botulinum toxin injection.

Lately, with Korean movie industry's development as well as people's more spare time, people's interest in multiplex grows higher. This paper is interested in relationships between service quality and customer's satisfaction in multiplex. The relationships are studied in the form of empirical hypothesis testing. The number of subjects in this study was 346 persons stayed at four multiplexes, among which we obtained valid responses from 326 persons through questionnaire investigation. Reliability was checked using Chronbach's alpha. For the hypothesis testing, used methods are Spearman's correlation, Mann-Whitney test, etc, and for statistical analysis, SPSS 10.1 software was used. Thus, we found statistically significant results : the relation between service quality and customer's satisfaction is positive, that is, the higher is customer's satisfactory evaluation in service quality which is measured by tangibleness, reliability, responsiveness, assurance, and empathy, the higher is customer's satisfaction level. In addition, we evaluated service quality level of four multiplexes, then we could know which multiplex was better and which was worse. With the information given in this paper we can attain higher customer satisfaction and notice how to operate multiplex effectively regarding service quality.

Background: lawsuits associated with medical troubles are increasing rapidly. Beginning with 69 cases in 1989, the annual rate of increase has reached above 36%. After the system of emergency medical specialist was born in 1995, it was expected that medical lawsuit cases would increase due to the importance of the emergency medical specialist's role to the emergent patients. Methods: A database was established for medical lawsuits(1982~1998, n=254), and lawsuits involving the emergency department(1982~1998, n=16) were selected from that database. Results: In criminal cases, the prosecutor's win rate was one out of four(25%). In civil cases, the prosecutor's win rate was 8 out of 10(80%); that is, the rate was higher than in general medical cases. Conclusion: To reduce the number of lawsuit following medical troubles in the emergency department, we should give careful attention and appropriate cure to patients who visit the emergency center.

This paper studied the relationship between customer intention and behavior in multiplex, and empirically compared four multiplexes with regard to customer behavior, where the four multiplexes were objects of our research. For our study a hypothesis were suggested about the relationship and tested. The number of subjects in this study was 346 persons stayed at four multiplexes, among which we obtained valid responses from 326 persons through questionnaire investigation. For the testing, used methods are Spearman's correlation, Mann-Whitney test, etc. Thus, we found statistically significant results. The relation between customer's intention and customer's real behavior is positive, where the behavior means that there has been real facts that he/she has revisited, informed by word of mouth, and stayed at multiplex in the past. Here only the relation was a little weak(p<0.1) between the revisit intention and facts that he/she has revisited in the past.

Purpose: Numbers and severity of the injured segments and neurological recovery patterns are both vague and confused following cauda equina syndrome (CES). We evaluated the characteristics of CES according to the causes of the injuries resulting in CES. Subjects and Methods: Thirty-nine cases of CES diagnosed by clinical features and electrophysiological studies were recruited. We investigated segments or roots involved, muscle strength grades of key muscles, external anal sphincter tones, and changing patterns of theses findings. Their characteristics were compared according to the traumatic and non-traumatic lesions. Results: In traumatic lesions, lower segments, such as sacral roots, were involved more frequently and severely (p<O.OOl). In non-traumatic lesions, L5 and Sl roots were more injured and S2,3,4 roots were less injured (p<O.05). However, there was no significant difference of severity among the injured segments in non-traumatic disorders. There was no typical recovery pattern in both traumatic and non-traumatic cases. Conclusions: In traumatic CES, lower segments or roots were injured more prevalently and severely. Relatively, upper segments were more affected in non-traumatic CES.

The studies is aimed to find out the problems and to devise its proper measure for prevention by reviewing and by analyzing the information derived from questionnaire method regarding the injury situation. At the result of survey conducted subject to the current 301 student dancer who are sampled from Universities throughout the seoul by random sampling. 1. It was found that 95% of dancer experienced injury while they play the dance and 63.5% of dancer experienced frequently 2. As the term of major is longer, the more the probability of injury, and the mortal the injury. 3. 66.1% of dancer had sawn the other dancer stop major because of injury. As we found in this article, in spite of the many studios on dance injury in many aspects, Injury prevention and self-cure was very lack. I conclude that more studies on prevention dance injury must be carried and most important thing is that dancer must take care oneself whenever dance and exercise.

Background : This study was performed to evaluate the prescribing pattern of β-lactam antibiotics and the relationship between antimicrobial resistance and antimicrobial use in 5 tertiary care hospitals in Korea. Materials and Methods : Data on annual patient-days and annual consumption (defined daily dose (DDD) per 100 patient-days) of β-lactam antibiotics from 2003 to 2005 in 5 tertiary hospitals were analyzed. To determine the antimicrobial resistance in K. pneumoniae, broth microdilution test and double disk synergy were performed according to the CLSI performance standards. Spearman's correlation coeffient was used to determine the relationship between antibiotic consumption and resistance. Results : The prescription of β-lactam antibiotics in 5 tertiary hospitals markedly varied. In two hospitals, increase in consumption of β-lactam antibiotics was more than 30% during recent 3 years. The higher consumption of β-lactam antibiotics significantly correlated with the higher rate of antibiotic-resistant K. pneumoniae in 5 tertiary care hospitals. Conclusion : Continuous surveillance of antibiotic use is needed to encourage appropriate prescribing of antibiotics and to reduce antibiotic resistance. 목적 : 항생제의 오남용으로 인한 내성균의 발현 및 급속한 확산이 전세계적으로 문제시 되고 있다. 특히 병원은 항생제 내성의 중심점에 있는 것으로 여겨진다. 본 연구에서는 최근 3년간 국내 5개 3차 병원의 β-lactam계 항생제의 사용량을 조사하고, 각 병원별 항생제 사용량과 K. pneumoniae의 항생제 내성률과의 상관관계를 알아보고자 하였다. 재료 및 방법 : 국내 5개 3차 병원에서 2003년 1월부터 2005년 12월까지 병원 입원 환자를 대상으로 연도별 재원연인원수와 각 β-lactam계 항생제의 총사용량을 수집하여 DDD (defined daily dose) per 100 patient-days로 환산하여 비교하였다. 2005년 6월부터 8월까지 각 병원의 임상검체에서 동정된 K. pneumoniae를 수집하여 액체배지미량희석법으로 항생제 감수성 검사를 시행하였고 ESBL(extended-spectrum β-lactamase) 생성 여부는 double disk synergy test를 시행하였다. 항생제 사용량과 내성의 상관관계는 Spearman 상관관계 분석을 시행하였다. 결과 : 5개 병원 중 3개 병원에서는 연도별 β-lactam계 항생제 사용량이 비슷하게 유지되었으나, 2개 병원에서는 2003년에 비해 2005년에 항생제 사용량이 30% 이상 증가하였다. β-lactam계 항생제 중 제제별 비율은 각 병원마다 차이가 있었으나, 3세대 cephaosporin의 사용이 가장 많았고 2세대 ceaphlosporin, β-lactam/β-lactamase inhibitor, 1세대 cephalosporin 순이었다. 경구용 β-1actam계 항생제의 사용량(r=0.900, P<0.037)과 2세대 cephalosporin의 사용량(r=0.900, P<0.037)은 각각 K. pneumoniae의 ESBL 생성과 양의 상관관계가 있었다. Ceftazidime의 사용량은 K. pneumoniae의 ceftazidime 내성률과 양의 상관관계가 있었다(r=0.900, P<0.037). 반면 imipenem의 사용량은 piperacillin/tazobactam 내성과 음의 상관관계가 있었다(r=-0.900, P<0.037). 결론 : 최근 3개년간 항생제 사용량은 병원별로 차이가 있으나 일부 병원에서는 증가하였다. β-lactam계 항생제의 사용량은 K. pneumoniae의 항생제 내성과 상관관계가 있었다. 항생제 사용을 줄임으로써 항생제 내성을 감소시킬 수 있을 것으로 기대되며, 병원별로 항생제 사용에 대한 지속적인 감시가 필요할 것이다.
