한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

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.

한명호,김범수,반명호 대한상하수도학회 2003 상하수도학회지 Vol.17 No.1

This study was carried out to treat the aqueous solutions containing reactive dyes(RB19, RR120 and RY179) by adsorption process using activated carbon fiber(ACF). And the changes of Trihalomethane Formation Potential(THMFP) in the model experimental system was investigated. ACF(A-15) has much larger specific surface area(1,584㎡/g-ACF) in comparison with granular activated carbon adsorbent(F400, 1,125㎡/g-GAC), which is commonly used, and most of pores were found to be micropores with pore radius of 2㎚ and below. It was found that RY179 has highest THMFP, and RB19 was most easily adsorbed among the dyes in this study. Increase and decrease of THMFP concentrations were observed before and after adsorption of reactive dyes on ACF(A-15). THMFPs per unit TOC were significantly decreased after adsorption of reactive dyes. And 70% of THMFP was decreased in adsorbed dye(RY179) solution. In the case of PCP(p-chlorophenol) and sucrose, which are single component adsorbate, adsorption capacities of ACF(A-15) were in good agreement with the batch adsorption measurement, and saturation time predicted of ACF columns for these components was also well agreed with practically measured time. But in the case of reactive dyes, which have relatively high molecular weight and aggregated with multi-components, adsorption capacities and saturation time predicted were not agreed with practically measured values.

Pernicious anemia is the most common cause of vitamin B12 deficiency and is caused by autoimmune destruction of parietal cell containing gastric mucosa region. This disease is significantly associated with autoimmune endocrinopathies and anti-receptor autoimmune disease. We report here a case of 26-year old man who was diagnosed pernicious anemia with high level of autoantibody titer (antithyroglobulin antibody 1:25,600 and antimicromosomal antibody 1:6,400) indicating subclinical Hashimoto's thyroiditis. Since other autoimmune diseases are frequently associated with pernicious anemia even without evidence of clinical symptoms, screening test for the presence of autoimmune disease should be evaluated in these patients.

반도체를 이용한 물의 광분해 : 콜로이드성 반도체촉매 ZnxCd₁-xS의 광활성

한명남,최석호,차민환 서울市立大學校 1997 論文集 Vol.31 No.-

Photosplitting of water based on the photocatalytic chemical reaction using ZnxCd1-xS, where x is 1, 0.5 and 0, was studied. DHP(dihexadecylphosphate)vesicle, HMP(hexametaphosphate)vesicle as stabilizer and benzyl alcohol as a donor were used respectively. The hydrogen volume generated on the several conditions by CdS was highest and decreased with x value. The rate of hydrogen generation increased with benzyl alcohol addition. Hydrogen generation experiment showed DHP is the better stabilizer than HMP and xenon lamp is the better light source than sun.

한명호 대한건축학회 2003 대한건축학회논문집 Vol.19 No.4

The aim of this study is to find out the planning methods of residential environment for sound amenity based on the concept of soundscape. Using the questionnaire survey in Namwon city, it was investigated the residents' consciousness of amenity and sound environment in residential areas, and analysed the importance and relationship between them. In this research, the factors of amenity are consisted of comfort, intimacy, modernity, health, vitality, and naturalness. Also, the group of sounds matching the surrounding are classified into natural sounds, artificial sounds(noise), traditional sounds, and working sounds(noise). The importance of sound group for amenity of residential area correspond to the order of natural sounds, traditional sounds, and working sounds. In order to improve the amenity of urban space in Namwon city, there is a necessity for considering the urban planning to manage natural sounds and traditional sounds. And artificial sounds and working sounds are playing a major part in improving vitality as one of the amenity factors.

한명호,윤태영,최중명,박순영 慶熙大學校 1991 論文集 Vol.20 No.-

This study was carried out to know physical growth and development, physical and nutritional indices, and maximum growth accelerating phenomena by semi―longitudinal method to measure body height, body weight, chest girth and sitting height of 427 of high school 3rd grade students who were living in Anyang city and born from March 1 in 1973 to February 28 in 1974. The result Were as follows : 1. Physical growth and development Body height grew one―step direct―development and body weight, chest―girth and sitting height grew two―step direct―development. Female excelled made in two―step development. Intersection phenomena of male and female showed in case of body height : 9.5 ∼ 13.5, body weight : 10.0 ∼ 14.0, chest―girth :11.5 ∼ 15.5, sitting height : 9.5 ∼ 14.0. During this periods, female excelled male but after these periods, male excelled female again. 2. Physical and nutritional indices In all cases of relative body weight, relative chest girth and relative sitting height it was found to be increasing thereafter with advancing ages. In cases of Ro¨hrer index and Kaup index it was found to be reaching to normal state thereafter with advancing ages. In either cases of Vervaeck and Pelidisi index, if was found to be increasing and teaching to normal state thereafter with advancing ages. 3. Maximum growth age of physiques M.G.A.'s were 12.31 for male and 10.42 for female which showed that M.G.A. for female appeared about 2 years earlier than that for male, in body height. M.G.A.'s were 12.73 for male and 11.65 for female which showed that M.G.A. for female appeared about 1 years earlier than that for male, in body weight. M.G.A.'s were 12.75 for male and 11.54 for female which showed that M.G.A. for female appeared about 1.2 years earlier than that for male, in chest ― girth. M.G.A.'s were 12.52 for male and 10.44 for female which showed that M.G.A. for female appeared about 2 years earlier than that for male, in sitting height.

Pulp Sludge를 이용한 이온교환체의 제조

韓明鎬,吳宣昊 慶一大學校 1997 論文集 Vol.14 No.2

The synthesis of Zeolite and Tobermorite though hydrothermal reaction of heat treated pulp sludge with NaOH, SiO₂and CaO were added to the pulp sludge ash as complement to make Ca/Si ratio to be 0∼1.6 and 2Na/Si, 0.6∼1.6. After 5 day's hydrothermal reaction of the mixture at 120℃, the compound was cooled at room temperature and filtered or centrifugalized. Then leansed with pure water and dried. By grinding the dried compound, ion exchange powder was prepared. X-ray diffraction of the powder showed that P-Type Zeolite was synthesized where Ca/Si ratio was in 0.15∼0.5 at the 2Na/Si ration of 0.67∼1.0, and Tobermorite was chiefly synhtesized where Ca/Si ratio was 0.75∼0.97 at the 2 Na/Si ratio of 0.67∼1.0. The hydrothermal synthesis in the same reaction condition at the temperature of 200℃ showed that Analcime was synthesized where Ca/Si ratio was 0.15 and Na/Si ratio was 1.0. The Tobermorite, hardly including the ash was synthesized where Ca/Si was 0.97, and 2Na/Si was 1.0.
