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.

과잉치는 치배 형성기에 정상 치판의 과도한 증식의 결과로 발생하며 산발적일 수도 있고 유전적일 수도 있다. 발생 빈도는 1~3%이며,2:1의 비율로 남아에게 호발한다. 주로 상악 전방부에서 많이 발견되며, 매복, 영구치의 위치 이상, 정중부 이개, 낭종, 비강으로의 맹출 등과 같은 다양한 합병증을 나타낼 수도 있다. 상악 전방부에서 발견되어지는 과잉치는 치축방향에 따라 위치가 결정되며 상악 전방부 과잉치의 1/3 정도는 역위 매복되어 맹출의 가능성이 없지만, 치낭의 치관 부위가 정상적인 관계로 존재하는 한 과잉치의 이동이 일어날 수 있다. 치아의 이동은 경구개, 소구치 부위, 비강까지도 일어날 수 있다. 또한 전상악 수직고경의 성장으로 시간이 지남에 라 외과적 접근이 어려워질 수 있다. 이에 본 두 증례에서는 역위 매복된 상악 전방부의 과잉치가 구개 측 중앙부까지 이동된 것을 발견하여 외과적으로 제거하였다. Supernumerary tooth develops as a result of abnormal proliferation of the dental lamina during the initiation stage of dental development. It could be a sporadic occurrence or a hereditary transmission. Supernumerary tooth occurs with a frequency of 1 to 3%, Generally, there is a 2:1 preference for boys. It is usually found in the anterior portion of the maxilla and may be associated with complications such as impaction, malposition of permanent teeth, formation of diastema, cysts and eruption into nasal cavity. The position of supernumerary tooth found in the anterior portion of the maxilla is determined by the axis of the tooth. One third of supernumerary tooth in the anterior portion of the maxilla has no possibility of eruption due to its invertedly impacted position. However, as long as the coronal part of the follicle remain intact, migration of supernumerary tooth is possible. The migration may occur into the palate, the premolar region, the sinus or the nasal cavity. Also, growth of vertical dimension of maxilla could make surgical approach difficult as time goes by. For this reason, we have found invertedly impacted mesiodens moved to the vault of the palate in the two cases, and extracted supernumerary tooth surgically.

The Waste generated in Korea have three main distinctive features such as heavy generation, highly portion of briquette ash and organic fraction of municipal solid waste(OFMSW). The management of wastes is confined into simple landfill, and furthermore the suitable landfilling site is subject to restriction. Therefore, Korea government has serious excutive problems to manage the wastes. The establishment of data-base and the evaluation of the characteristics about wastes should be done before any affair. Therefore, in this study, such characteristics as OFMSW form, cooking condition, three composition, density, element analysis, and heating value were evaluated. According to the results of this study, generated from domestic kitchen have vegetable waste more than half of total kitchen wastes, and is characterized by high moisture content, low heating value. In addition, it was found that the improvement of food distribution system and meal preparation program would be the most powerful method to reduce the wastes, and reducing the moisture content from the wastes could make the cost of the wastes management cheaper.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.

본 연구는 마산만 저질과 패류(바지락)틀 채취하여 중금속 함량을 측정함으로서 마산만의 중금속에 의한 오염현황을 파악하고자 하였다. 전반적으로 저질의 평균농도는 Zn, Pb, Cu, Cr, Cd의 순으로 각각 109.54, 26.01, 22.41, 15.99, 0.20㎍/g이었으며, 바지락의 평균농도는 Zn, Cu, Cr, Pb, Cd의 순으로 각각 19.44, 0.7, 0.49, 035, 0.07㎍/g으로 나타났다. 각 지점별 저질의 중금속 농도는 S1 지점과 S6 지점에서 높은 함량을 보였으며 패류의 경우 S1지점에서 높은 경향을 보였다. 저질과 패류의 함량 비교에 있어 Zn, Cu, Pb의 경우 저질의 함량이 패류외 함량에 어느정도 영향을 미치고 있음을 알 수 있었으나, Cr과 Cd의 경우 저질과 패류간의 뚜fut한 상관관계성을 볼 수 없었다. The purpose of this study was investigate the heavy metal contents in sediment and shellfish samples in Masan Bay on May 1993. Atmospheric absorption spectrophotometric results showed that the mean values of the mean value of the heavy metal contents detected from sediment samples were very high in the order of Zn(109.54㎍/g), Pb(26.01㎍/g), Cu(22.41㎍/g), Cr(15.99㎍/g), Cd(0.2㎍/g), and that the metals in shellfish samples were also high in the order of Zn(19.44㎍/g), Cu(0.7㎍/g), Cr(0.49㎍/g), Pb(0.35㎍/g), Cd(0.07㎍/g) in general. The metal levels in sediments from Nampo(S1) and Bongam(S6) and that in shellfishes from Nampo(S1)were high in concentration compared with those of the other sites. The higher residue levels uf Zn, Cu, and Pb in both the sediments and shellfishes suggested that the metal levels in shellfishes might be affected by the metal contents in sediments to some extent, although there was no certain correlation between the residue contents of Cr and Cd in sediment and shellfishes.

대장 지방종은 주로 우측 결장에 호발하고 특히 회맹판 부위와 맹장 부위에 호발한다. 또한 50~60대에 빈도가 높고 증상이 있는 환자에서 장중첩증이 높게는 40~50%에서 보고되고 있어 성인 장중첩증의 원인으로 중요한 비중을 차지한다. 특히 성인 장중첩증 및 장폐쇄의 중요 원인인 악성 종양과 임상 양상이 유사하여 감별진단이 중요하다. 저자들은 반복적인 복통을 주소로 내원한 환자에서 맹장의 4×5㎝의 점막하 지방종이 말단 회장부위와 반복적인 장중첩중이 발생했던 1례를 부분 절제술로 치료하여 양호한 임상 경과를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lipomas are one of the most common benign nonepithelial tumors of the colon which are often detected incidentally by radiologic investigation or on operation. These tumors are usually without specific symptoms. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve and the cecum. Most patients are asymptomatic. but tumors larger than 2 cm tend to produce a change in bowel habit. abdominal pain. rectorrhagia and complications including luminal obstruction or intestinal intussusception. Diagnosis can be made by colonoscopy abdominal CT. MRI, or barium enema. We report a case of lipoma of the cecum that originated in the submucosa and presented as a intussusception in a 50-year-old woman with a brief review of the literature.

As part of a fundamental study on the volume reduction of contaminated concrete wastes, the separation characteristics of the aggregates and the distribution of the radioactivity in the aggregates were investigated. Radioisotope $^{60}Co$ was artificially used as a model contaminant for non-radioactive crushed concrete waste. Volume reduction for radioactively contaminated dismantled concrete wastes was carried out using activated heavy weight concrete taken from the Korea Research Reactor 2 (KRR-2) and light weight concrete from the Uranium Conversion Plant (UCP). The results showed that most of the $^{60}Co$ nuclide was easily separated from the contaminated dismantled concrete waste and was concentrated mainly in the porous fine cement paste. The heating temperature was found to be one of the effective parameters in the removal of the radionuclide from concrete waste. The volume reduction rate achieved was above 80% for the KRR-2 concrete wastes and above 75% for the UCP concrete wastes by thermal and mechanical treatment.

<P><B>Abstract</B></P> <P>The aim of the paper is to describe the current status of management for the decommissioning of combustible waste in KAERI. In Korea, two decommissioning projects have been carried out due to the retiring of nuclear research facilities, i.e., the Korean research reactors (KRR-1 & KRR-2) and a uranium conversion plant (UCP). The decommissioning of KRR-2 and the uranium conversion plant (UCP) at KAERI were completely finished by 2011, whereas the decommissioning of KRR-1 is currently underway. For the purpose of a volume reduction of the combustible waste generated from the decommissioning projects, incineration technology has been selected for the treatment of combustible waste. About 16.4tons of combustible waste has been treating using Oxygen Enriched Incineration. The temperature; pressure of the major components; stack gas concentrations, i.e., SO<I> <SUB>x</SUB> </I>, NO<I> <SUB>x</SUB> </I>, CO, CO<SUB>2</SUB> and HCl; and residual oxygen were measured. The major parameters measured during normal operation were sustained at a stable status within criteria of the operation condition. Oxygen enriched air, 22vol.% (dry basis) was used for stable incineration. The volume reduction ratio achieved was about 1/65.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Oxygen Enriched Incinerator. </LI> <LI> Decommissioning combustible waste. </LI> <LI> Volume reduction of radioactive waste. </LI> </UL> </P>
