연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

A 1948 paper by Robert Merton established that certain social events were, to a large extent, influenced by the expectancy effects in different social settings. It wasn’t until 20 years later that Merton’s concept of the self-fulfilling prophecy came to the attention of educational researchers (Clark, 1963; Goldberg,1963). Since the Oak Elementary School experiment, researchers have conducted well over 100 studies relative to teacher expectations. It is also important to note that impressions about a certain student may not be the same for two or more teachers. Futhermore, after an extensive review of the literature, Brophy and Good(1974) concluded that teachers, irrespective of gender, are more negative toward young males, particularly regarding their potential as behavior problems. In a follow-up study(Martinek & Karper, 1984a), it was discovered that the attractiveness cue was more influential in expectancy formation for older age groups than for younger ones. These data suggested that as children get older, attractiveness becomes increasingly related to performance expectations.

This study has been carried out to clear chip shape, chip formation and cutting mechanism of thermoplastic rigid polyvinyl chloride with low speed orthogonal cutting. The results obtained are as follows; 1. The chip shapes are classified flow type chip and shear type chip, they are became flow type as tool rake angle increases, according as cutting depth and cutting speed decreases. 2. The shear pitch zone of shear type chip is approached cutting depth. 3. The size effect is existed such as the metal cutting. 4. The friction coefficient decreases by increasing cutting depth, and it increases by increasing tool rake angle. 5. The experimental points are approached to some degree Ernst-Merchant's cutting equation, but the cutting equation of the given condition is obtained 1,47φ+β-α =2/5π.

Background : Communite-acquired peumonia (CAP) is one of the leading causes of mortality and morbidity. Despite progress in diagnostic techniques and treatments, management of pneumonia remains challenging, because the precise etiology remains uncertain in as many as 49% of cases. The limitaions of identifying etiologic agents make it necessary to use empiric antibiotics in almost all patients, and furthermore emergence of antibiotic-resistant organisms pose difficulties to the selection of an empiric antibiotic regimen. For the optimal choice of empirical antibiotics, we should know the frequency of etiologic agents and antimicrobial resistance rates in the community. Methods : A prospective multicenter study of community-acquired pneumonia in Korea was carried out between May 1997 and April 2000. The microbiologic diagnosis was based on the results of sputum culture, blood culture and pleural culture. Results : Five hundred eighty eight cases of community-acquired peumonia in 562 patients admitted to the hospitals. The mean age was 59.9 with male predominance (58.3%), and 370 (63%) had underlyin gillness. The etiologic agents were identified in 38.3%, and the list of individual agents, in decreasing order, was Streprococcus pneumoniae (21.7%), Klebsiella pneumoniae (14.8%) Pseudomonas aeruginosa (9.8%), Staphylococcus aureus (9.5%), viridans group streptococci (5.7%), Enterobacter cloacae (4.2%), Hemophillus Influenza (3.8%), The rates of admission to the intensive care unit was 10.4%. The motality was 7.1%. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Forty percents of S. aureus were methicillin-resistant S. aureus. K. penumoniae were susceptible to cephalosporin and quinolone. Conclusion : In Korea, S.pneumoniae is the most important agent causing community-acquired pneumonia. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Gram negative bacteria such as K. pneumoniae, P. aeruginosa showed high incidence when compared with that of other countries. Most of them had underlying diseases including bronchiectasis and chronic obstructive pulmonary diseases. (Korean J Infect Dis 33:1∼7, 2001)

The electrolyte solid films for the rechargeable Li-ion thin film batteries were deposited by RF sputtering method using a Li3PO4 sputter target and increasing RF power under a flowing N2O or N2 atmosphere. The chemical bond structures were spectroscopically analyzed by using FTIR (fouler transform infrared spectroscopy) and XPS (x-ray photoelectron spectroscopy). The FTIR absorption spectra of the films exhibited two principal stretching bands, one associated with the PO3 stretching mode and the other with the P-O-P stretch mode. The XPS N1s peaks located at 398.2∼404.5 eV indicated that the N bond structure in the film consisted of chemical bonds, such as nitride bonded to P and/or Li atoms. To be influenced by the nitrogen, the ionic conductivity of the films deposited Using N2 has to be 10 orders of magnitude higher than that of the films deposited Using N2O.

Actinomycosis is a chronic suppurative and granulomatous disease, characterized by abscess formation, tissue fibrosis, and draining sinuses. Actinomycosis of the gallbladder is very rare and has not yet been reported in Korea. We report a case of actinomycosis of the gallbladder in an 80-year-old women with history of cholelithiasis for 3 years, preoperatively misidentified as gallbladder cancer. Histologic section of the gallbladder showed Gram-positive branching bacilli compatible with actinomyces. After cholecystectomy, the patient received intravenous ampicillin for 4 days, followed by amoxicillin for 4 months thereafter.
