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.

본 연구는 폐석재와 석분을 사용하여 친환경적인 식생블럭 제품을 개발하기 위하여 폐석재의 입경과 석분의 첨가량을 각각 3종류씩 총 9종류의 식생블럭에 대하여 단위중량, 공극율, 투수량, 압축강도, 쪼갬인장강도, 휨강도, 내산성, 알카리농도에 대하여 구명하였다. 단위중량, 강도, 내산성은 골재의 입경이 작을수록 석분의 혼입량이 많을수록 크게 나타났으며, 공극율과 투수량은 작게 나타났다. 강도는 중성화 처리 유무에 따라 4∼5% 정도의 미소한 차이가 나타났다. 알카리 농도는 중성화 약품처리, 수중용출, 야외폭로 순으로 효과가 크게 나타났으며, 이는 식생블럭의 중성화 방법 선택에 매우 중요한 내용이라 할 수 있다. 또한, 식생상태는 공극율과 골재의 입경이 큰 식생블럭이 생육에 유리한 것으로 나타났다. This study was performed to develop the environment-friendly plantable block and to evaluate unit weight, void ratio, permeability, strength, acid-resistance and value of pH by the change of the grading of waste stone and the addition amount of stone dust. The unit weight, strength, acid-resistance is increased with small size of waste stone with increase of the addition amount of stone dust. But, the void ratio and permeability is decreased. The strength of neutral plantable block is decreased approximately 4-5% than that of the normal plantable block. The decreased effect of pH increased in order to neutral treatment, underwater leaching and field exposure. It is very important contents in neutral method selection of plantable block. Also, the planting state is grown rapidly with increase of the void ratio and of the waste stone size, approximately.

전기천,강시환,박광순,김상익 경남대학교 환경문제연구소 1990 환경연구 Vol.12 No.-

최근 한반도를 통과했던 태풍 중 그 규모가 커서 海上에서 발생된 颱風波浪에 의해 특히 남해안 지역에 큰 재해를 준 1986년 태풍 Vera(8613)호 통과시에 南海의 거문도와 거제도 海上에서 동시에 태풍파랑을 관측하였다. 관측된 태풍파랑의 재현을 위하여 유럽의 북해를 대상으로 최근 연구개발된 Hybrid Parametric Wave Model(HYPA)을 적용하여 Vera 통과시의 파랑분포를 수치적으로 계산하였으며, 그 계산결과를 관측치와 비교하였다. 또한 태풍파랑의 추정에 주로 사용되어온 Wilson모델의 결과와도 비교하여으며, HYPA모델의 결과가 Wilson모델에 비해 훨씬 관측된 파랑자료에 근접함을 보였다. 따라서 본 연구를 통해서 한반도 근해상에서 발생되는 태풍파랑의 예측과 추정에 있어 HYPA모델에 매우 정확함을 보여주었다. During the passage of Typhoon Vera(8613) which causes the heavy natural disasters, especially, on the southern coast of Korea, waves were simultaneously measured at two different locations of the South Sea, that is, near to the Geomun and the Geoje Islands. In order to reproduce the measured typhoen-waves, Hybrid Parameteric Wave Model(HYPA) which has been developed for the North Sea was adopted to calculate numerically the waves generated by the Typhoon Vera. The model results were jilter-compared with the measured waves, and also with the results of Wilson model which has been widely used for the hindcast of typhoon-waves. HYPA's results show in the closer ageement with the measured waves than those of Wilson's. Based on these comparisons, HYPA model can be used for more accurate forecast and hindcast of typhoon-waves in Korean Seas.

The human proteomics-based approaches, which examine the expressed proteins of a tissue or cell type, are increasingly being used. Venous occlusion is commonly employed for stimulating tissue-plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-l) release from venous endothelial cells, and this has been regarded as a parameter of the individual fibrinolytic capacity of plasma. The present work involved a detailed investigation of the plasma proteome and fibrinolytic activity in normal subjects, with the aim of determining whether correlations exist between various parameters of the fibhnolytic system before and after venous occlusion. We analyzed fibhnolytic parameters and plasma proteome before and after 15-min periods of venous occlusion in the forearm in 10 healthy 3rd-decade volunteers. Proteome analysis was performed using two-dimensional gels. The tryptic digests of some proteins were confirmed by MALDI-TOF and the MS-Fit algorithm. The fibrinolytic response as measured by the absolute amount of t-PA after venous occlusion was increased by venous occlusion (5.5 vs 9.6 ng/㎗, p<0.05), as was PAI-l (46.8 vs 56.1 ng/㎗, p<0.05). However, two-dimensional electrophoresis finding was virtually nonspecific and inconsistent after venous occlusion in healthy male subjects. Venous occlusion does not influence plasma proteome in healthy males. Although the fibhnolytic response to venous occlusion is attributed to an increase in free tUPA antigen, this change is not correlated with plasma proteome.

이상익,김영재,이상훈,김종철,한세현,장기택 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

자해 행위(self-injurious behavior)란 자살 의도 없이 자신의 신체 일부를 무의식적 혹은 고의로 손상시키는 것으로 정의한다. 이는 머리 및 몸 때리기, 피부 절단 혹은 손가락 깨물기 등의 형태로 나타나며, 눈, 성기 및 구강 내 자해 행위(self-inflicted oral mutilation)를 포함한다 자해 행위는 일반적으로 정신지체, 혼수상태, 정신과적 문제, 약물의 독성 혹은 성격장애를 지닌 환자에게서 일어날 수 있다 소아 환자에서 자해 행위는 보통 입술, 협점막 및 혀 깨물기 둥이 보고되고 있으며, 이러한 구강 내 자해 행위를 방지하기 위해 치과적 조절 방법들이 소개되고 있다. 본 증례에서는 구강 내 자해 소견을 보인 두 명의 소아 환자들에 대해, 각각 변형된 activator 형태의 가철성 장치, 후방으로 연장된 tongue-rake 장치 및 mouth guard 둥을 사용하여 양호한 치유과정을 보였기에 보고하는 바이다. Self-injurious behavior is defined as deliberated harm to one's own body without suicidal intent. It usually occurs as head banging or hitting, body hitting, skin cutting, or finger biting and includes ocular, genital, and self-inflicted oral mutilation. Self-injurious behavior can occur with mental retardation, coma, psychotic problem, poisoning, or character disorders. In pediatric patients, self-injurious behavior usually is reported to lip, cheek and tongue biting, and many kinds of dental management methods have been introduced to prevent self-injurious behavior patients from self biting. This report presents two self-inflicted oral mutilation patients who were all treated successfully with appliances such as modified activator without wire for retention, modified tongue-rake appliance and mouth guard.
