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.

Although Korean influenza virus isolates have been genetically associated with the vaccine strains of the corresponding year, influenza B viruses have prevailed almost every year in Korea during the past decades. We have 'analyzed the genetic characteristics and evolutionary patterns of the haemagglutinin (HA) 1 domains of influenza B viruses isolated during 1988-1999 using direct RT-PCR and sequencing. Phylogenetic analysis of influenza B viruses isolated in Korea indicated that antigenically and genetically distinguishable strains of the lineage II and lineage III variants had been cocirculated. Variants prevailed in early 1990s are represented in 1996/97 and 1998/99 and some different variants have been co circulated geographically and prevailed concurrently in Korea. All HA1s of Korean isolates have amino acid substitutions mainly in the region between position 124 and 310, which was previously proposed an immunodominant region. Insertion-deletion patterns of the HA gene revealed that Korean influenza B viruses were evolved from Lee40 with different manner between lineage II and III viruses. Lineage III viruses were also divided into two groups as conserved group and inserted group, in relation to Lee40. But lineage II viruses had evolved with directional pattern. Antigenic index proposed that influenza B isolates prevailed since 1996/97 seasons might had emerged from the antigenic variants of a Seo1697-like virus and that new variants might appear from the lineage II viruses resulting in persistent prevalence in Korea.

이영미,박혜순,천병철,김현수 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 비만 자체보다 복부비만이 심혈관질환과의 관련성이 높아 복부비만에 대한 평가는 점점 그 중요성이 강조되고 있다. 허리둘레는 측정이 간편하여 복부비만의 평가에 가장 적절한 지표로 알려져 있다. 그러나 기관에 다라 권고하는 측정부위가 다르고, 우리 나라에서는 아직 허리둘레 측정위치에 대하여 표준화되어 있지 않다. 이에 허리둘레 측정부위 중 신뢰도가 가장 높은 방법을 찾고자 연구를 시행하였다. 방법 : 본 연구에 자발적 참여를 원하는 자원자 111명 (남자 53명, 여자 58명) 을 대상으로 하였다. 허리 둘레는 (1) 늑골 하단부와 장골능 상부의 중간 부위 (WHO 권고 방법 ) (2) 배꼽 부위 (3) 장골능 상부 (NIH 권고 방법) 세 곳의 해부학적 위치에서 측정하였다. 공복 상태에서 훈련된 2명의 검사자에 의해 측정부위별로 각각 2회씩 허리둘레를 측정하였다. 측정자내 및 측정자간 변이의 비교는 일반선형모델 (general linear model)을 이용하였다. 결과 1) 대상자의 평균연령은 38.4세였으며 체질량지수 25 kg/㎡를 기준으로 정상 체중군은 66.1%, 비만군은 33.9%였다. 2) 세 가지 측정법의 비교 결과, WHO 방법과 배꼽 부위가 NIH 방법보다 측정자내, 측정자간 및 총 변이가 유의하게 적었다. WHO 방법과 배꼽 부위에서의 측정값은 WHO 방법이 변이가 더 적었으나 통계적으로 유의하지는 않았다. 3) 여자, 40세 이상 및 체질량지수가 25 kg/㎡ 이상인 군에서는 변이에 유의한 차이가 없었다. 결론 : 늑골 하단부와 장골능 상부의 중간 부위에서 허리둘레를 측정하는 WHO 방법과 배꼽부위에서 측정하는 방법이 장골능 상부에서 측정하는 NIH 방법보다 측정자내, 측정자간 및 총 변이가 더 적었다. 허리둘레의 측정은 복부비만을 평가함에 있어 중요한 도구이므로 이러한 자료를 바탕으로 허리둘레 측정부위를 표준화하는 것이 필요하다. Background : Assessment of waist circumference is being emphasized for the evaluation of fat distribution. However, the sites for measurement of waist circumference differ depending on the associations or the investigators. the standardization of waist circumference has not yet established in Korea. The purpose of this study was to find the site for reliable measurement of waist circumference in the subjects with various range of age, and BMI. Method : The participants were recruited 111 persons (53 males and 58 females) participated in this study voluntarily. All anthropometric values of study subjects were measured in fasting state with swimming suit. Waist circumference was measured by two trained personnel at 3 different sites; (1) WHO recommended site : midpoint between the lower border of the rib cage and the iliac crest; (2) umbilical level; (3) NIH suggested site: top of the iliac crest. Intra-observer, inter-observer, and total variations were analyzed. Results : Intra-observer, inter-observer, and total variations of waist circumference measured at which WHO recommended, and umbilical level were lower than that of waist circumference measured at which NIH suggested. However, the difference of variations between the values of WHO method and that measured at umbilical level was not significant. The difference of variations was more prominent in female, subjects aged over 40 years, and subjects with BMI <25 kg/㎡. Conclusion : The variations of waist circumference measured at which midpoint between the lower border of the rib cage and the iliac crest, or umbilical level were lower that measured at which top of the iliac crest. It is needed to standard the site for measurement of waist circumference to assess abdominal obesity precisely in practice.

이진숙,김병수,권혁일 대한건축학회 2003 대한건축학회논문집 Vol.19 No.7

Glare in one of the major factors influencing comfort appraisal for lighting. Although a predictive formula for such glare has been proposed by CIE, it has not been investigated for domestic adjustment. The correlation between glare and the closely related dazzling-sensation has not been investigated enough. In the study, subjective discomfort glare appraisal and dazzling-sensation appraisal for discomfort glare was performed to produce a corrected UGR formula. Analyses between appraisal for dazzling-sensation and results of subjective appraisal for discomfort glare were performed to produce a formula that could represent the correlation between discomfort glare and dazzling-sensation. The results of the comparison and analysis is that results computed by UGR differed from those of subjective perception, so a corrected UGR formula and corrected glare index and dazzling-sensation was produced. Also, a formula that could represent the state of dazzling-sensation verying with change of luminance was produce.
