This Study is to make a environmental education plan for young children for the plan, the objective, substance, method, evaluation of recent environmental education are reviewed in relation with the importance of E.C.E(Early Chilhood Education), young dhild development, E.C.E curriculum sand educational environment. The result shows the needs and possibility for the effective environmental education in the kindergarten. It is also shown some problem in the current situation such as the lack of systematic efforts in developing programs and educational materials. Therefore a plan for the systemic environmental education in the kindergarten is proposed as follows : 1. Appropriateness, integration, and relation must be accomplished. 2. The basic objective is to establish appropriate value and attitude. 3. The substance is to induce the young children to love animals and plants 4. The method is through the experiences in the every day life 5. Physical space, materials, and equipment are needed for cognition of ecological principles. 6. Effective educational materials are needed for young childrens activity. 7. The evaluation has developing skills for emotional area and young children. 8. Teacher education should be reinforced. 9. Kindergarten program must relation with home and society. 10. Kindergarten program should be localized.

<P>Oxidative stress is one of the most important factors in reducing adult hippocampal neurogenesis in the adult brain. In this study, we observed the effects of Cu,Zn-superoxide dismutase (SOD1) on lipid peroxidation, cell proliferation, and neuroblast differentiation in the mouse dentate gyrus using malondialdehyde (MDA), Ki67, and doublecortin (DCX), respectively. We constructed an expression vector, PEP-1, fused PEP-1 with SOD1, and generated PEP-1-SOD1 fusion protein. We administered PEP-1 and 100 or 500 관g PEP-1-SOD1 intraperitoneally once a day for 3 weeks and sacrificed at 30 min after the last administrations. PEP-1 administration did not change the MDA levels compared to those in the vehicle-treated group, while PEP-1-SOD1 treatment significantly reduced MDA levels compared to the vehicle-treated group. In the PEP-1-treated group, the number of Ki67-positive nuclei was similar to that in the vehicle-treated group. In the 100 관g PEP-1-SOD1-treated group, the number of Ki67-positive nuclei was slightly decreased; however, in the 500 관g PEP-1-SOD1-treated group, Ki67-positive nuclei were decreased to 78.5% of the vehicle-treated group. The number of DCX-positive neuroblasts in the PEP-1-treated group was similar to that in the vehicle-treated group. However, the arborization of DCX-positive neuroblasts was significantly decreased in both the 100 and 500 관g PEP-1-SOD1-treated groups compared to that in the vehicle-treated group. The number of DCX-positive neuroblasts with tertiary dendrites was markedly decreased in the 500 관g PEP-1-SOD1-treated group. These results suggest that a SOD1 supplement to healthy mice may not be necessary to modulate cell proliferation and neuroblast differentiation in the dentate gyrus.</P>

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.

In this report, we present a case of the male pseudohermaphrodite in a beagle dog. The animal was subjected for examination due to enlargement of clitoris that was shown as reddish finger-like structure protruding from the vulva. Visual examination of the internal genitalia revealed that the animal possessed both testes and uterus. Based on the findings of physical examination and exploratory laparotomy, it was tentatively diagnosed as male pseudohermaphrodite. Internal genitalia and enlarged clitoris were removed for the prevention of pyometra and Sertoli cell tumor.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et al., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(1997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.

BMP test를 통한 음폐수와 하수슬러지의 병합소화 특성 평가

이수영ㆍ윤영삼ㆍ강준구ㆍ김기헌ㆍ신선경(Su young LeeㆍYoung Sam YoonㆍJun Gu KangㆍKi Heon KimㆍSun Kyoung Shin) 유기성자원학회 2016 유기물자원화 Vol.24 No.1

혐기성 소화의 주요 조건 중 하나인 C/N비의 경우 하수슬러지는 5.40으로 낮게 나타난 반면 음폐수(Food waste leachate)는 21.84로 높게 나타났다. C/N비가 낮을 경우 혐기성소화의 저해 요인으로 작용될 수 있기 때문에 음폐수의 높은 유기물 농도 및 C/N 비를 활용하여 메탄가스 발생량 증가시킬 수 있었다. Tchobanoglous이 제안한 이론적 메탄가스 발생량 예측수식을 적용하여 메탄 및 바이오가스 발생량을 산정한 결과 하수슬러지 단일 혐기소화의 경우 305.6 mLㆍCH4/gㆍVS, 689.4 mLㆍCH4/gㆍVS의 메탄, 바이오가스가 발생하였고 음폐수 : 하수슬러지를 1:9로 혼합한 시료는 약 322 mLㆍCH4/gㆍVS, 3:7시료에서는 약 354 mLㆍCH4/gㆍVS, 5:5시료에서는 약 386 mLㆍCH4/gㆍVS의 메탄가스가 발생하는 것으로 분석되었다. BMP 실험 결과 1:9, 3:7, 5:5 비율로 병합 처리한 경우 각각 약 233, 298, 344 mLㆍCH4/gㆍVS의 메탄가스가 발생하였다. 따라서 음폐수의 혼합비율이 높아질수록 메탄가스 발생량은 증가하였고 하수슬러지와 음폐수의 혼합 비율에 따른 병합처리 시 하수슬러지 단독처리에 비해 다량의 메탄가스가 발생되었다. BMP 실험을 통해 생산된 메탄가스의 누적생산 곡선을 Modified Gompertz model과 first order kinetic model에 적용하여 추정한 결과, 메탄생성량은 Modified Gompertz model에서는 238.5, 302.3, 353.6 mL/gㆍVS 발생하였고 first order kinetic model에서는 242.8, 312.5, 365.5 mL/gㆍVS로 음폐수와의 혼합비율이 증가할수록 높게 나타났으며, 최대 메탄생성속도의 경우 3:7비율에서 48.2 mL/gVSㆍday로 최대 메탄생성 속도를 보였다. first order kinetic model의 1차 반응속도상수 k값은 1:9, 3:7, 5:5 비율에 따라 0.32, 0.22, 0.08day-1 나타났다. 1차 반응속도 상수의 경우 음폐수의 혼합비율이 낮을수록 높게 나타났다. Modified Gompertz와 first order kinetic model 모두 실험결과를 잘 모사하였으며, 실험결과와 모의결과의 적합도를 나타내는 상관계수(R2)의 경우 0.92∼0.98으로 높은 상관성을 나타내었다. We mix food waste leachate and sewage sludge by the proportion of 1:9, 3:7 and 5:5. It turns out that they produced 233, 298 and 344 CH4ㆍmL/gㆍVS of methane gas. The result suggests that as the mixing rate of food waste leachate rises, the methane gas productions increases as well. And more methane gas is made when co-digesting sewage sludge and food waste leachate based on the mixing ratio, rather than digesting only sewage sludge alone. Modified Gompertz and Exponential Model describe the BMP test results that show how methane gas are produced from organic waste. According to the test, higher the mixing rate of food waste leachate is, higher the methane gas productions is. The mixing ratio of food waste leachate that produces the largest volume of methane gas is 3:7. Modified Gompertz model and Exponential model describe the test results very well. The correlation values(R2) that show how the results of model prediction and experiment are close is 0.92 to 0.98.

YOO, Dae Young,NAM, YoonYi,KIM, Woosuk,YOO, Ki-Yeon,PARK, Jaeil,LEE, Choong Hyun,CHOI, Jung Hoon,YOON, Yeo Sung,KIM, Dong-Woo,WON, Moo-Ho,HWANG, In Koo Japanese Society of Veterinary Science 2011 The Journal of veterinary medical science Vol.73 No.1

<P><I>Ginkgo biloba </I>leaf extract (Gb) has been known to improve blood flow and preclude the tissue from free radical damage. Effects of Gb were examined by using Ki67, a specific proliferative marker for cellular proliferation, and doublecortin (DCX), a marker for immature neurons, indicating degree of neuroblast differentiation in the hippocampal dentate gyrus (DG) of adult C57BL/6 mice. The mice were fed with Gb at 40 and 100 mg/kg once daily for 28 days. The increase of Ki67- and DCX-immunoreactive cells in the DG was increased in a dose-dependent manner. Especially, the group having 100 mg/kg Gb showed a significant increase of DCX-immunoreactive neuroblasts with well-developed tertiary dendrites. Expression of DCX protein in the Gb groups was also significantly increased upon compared with the vehicle group. The results suggested that repeated intake of Gb would enhance cell proliferation and neuroblast differentiation in the mouse DG.</P>

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.
