Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

본 연구는 온실의 난방 에너지 절감을 목적으로 온실 내부에 알루미늄 온수배관을 설치하여 난방효과에 대한 기초자료를 구축하고자 수행되었다. 그 연구결과를 요약하면 다음과 같다. 전체 실험을 포함하여 온실내의 높이별 온도편차는 4.0~7.0℃ 정도의 범위로서 그 차이가 크게 나타났다. 팬코일유니트(FCU)를 작동시킨 경우가 작동시키지 않은 경우에 비해 유출입수의 온도차가 3.3℃ 정도 크고, 소비전력량은 36.2~40.1% 정도 증가하였으며, 시간당 방열량은 44.6~52.0% 정도 증가하는 것으로 나타났다. 실험기간동안 순환유량은 0.48~0.49L · s<SUP>?1</SUP> 정도의 범위에 있었고, 평균유속은 1.53~1.56m · s<SUP>?1</SUP> 정도였다. 유출입수의 평균 온도차는 6.24~11.50℃이었다. 최저 외기온 ?14.0~?0.6℃ 범위에서 설정온도별 방열량은 135,930~307,150㎉ 정도의 범위로서 시간당 9,610~19,630㎉ · h<SUP>?1</SUP> 정도의 범위에 있었다. 이것은 최대난방부하의 약 23~53% 정도의 난방에너지를 공급할 수 있을 것으로 나타났다. 전체 방열량과 소비전력량은 각각 2,548,306㎉ 및 3,075.7㎾h이다. 화석연료인 경유로 난방할 경우, 소요되는 경유의 총 소비량은 281.6L 정도이고 비용은 321,000won인 것으로 나타났다. 농가용 전력요금을 적용하면 전력사용에 대한 총비용은 110,730won 정도로서 경유 소비 비용의 33.5% 정도로 나타났다. 실험구의 온도가 대조구보다 약 8.3~14.6℃ 정도 높게 나타났다. This research was conducted to obtain basic data with regard to the heating performance that would be produced by installing an aluminum hot water pipe inside the greenhouse with the goal of reducing the heating energy in greenhouse. The research results are summarized as follows. The degree of difference in relation to the temperature by height within the greenhouse during the entire experiment was significant - within the range of 4.0~7.0℃. The temperature difference between incoming and outgoing water was about 3.3℃ greater when FCU was activated compared to when it was not activated. Meanwhile, the amount of energy consumed increased about 36.2~40.1%. The amount of pyrexia per hour also increased by 44.6~52.0%. During the experiment period, circulated flux was within the range of 0.48~0.49 L · s<SUP>?1</SUP> while average fluid speed was 1.53~1.56 m · s<SUP>?1</SUP>. The average temperature difference between incoming and outgoing water was 6.24~11.50℃. The amount of heating value by each set temperature within the minimum outdoor temperature range of ?14.0~?0.6℃ was 135,930~307,150 ㎉, and the range was within the 9,610~19,630 ㎉ · h<SUP>?1</SUP> per hour. This demonstrated that about 23~53% heating energy of the maximum heating load could be supplied. Total radiating value and amount of energy consumed were 2,548,306 ㎉ and 3,075.7 ㎾h, respectively. When heating takes place using oil, which is a fossil fuel, the total amount of light oil consumed was 281.6 L while the cost was 321,000 won. When the electricity cost for farms is applied, the total cost was about 110,730 won, which is about 33.5% of the cost required compared to oil consumption. The temperature at in the experiment area was about 8.3~14.6℃ higher compared to that of the control area.

신양수,조희충,김원식,국기용,김용화,정종훈,문철웅,배학연,양성훈 朝鮮大學校 附設 醫學硏究所 1992 The Medical Journal of Chosun University Vol.17 No.2

Endothelin(ET) is a 21-residue peptide originally isolated from the cultured porcine endothelial cells. There are at least three genes for endothelin:endothelin-1(ET-1), endothelin-2(ET-2), and endothelin-3(ET-3). Endothelins are present in various human biological fluids including plasma, urine, breast milk, and saliva and have been found elevated plasma ET concentrations in patients with diabetes mellitus, Patients undergoing maintenance hemodialysis due to chronic renal failure, patients with acute myocardial infarction, and patients with subarachnoid hemorrhage. Endothelial cell damage is suspected to occur in diabetic patients and may be one important cause of angiopathy, a major complication in diabetes mellitus. The elevation of ET in diabetic patients may be a marker of, and further exacerbate, their vascular disease. We measured the levels of ET-1 in plasma of 50 patients with non-insulin dependent diabetes mellitus(NIDDM) and 25 normal subjects by radioimmunoassay. The plasma ET-1 concentration (mean±S.D.) in NIDDM was 6.461 A2.510 f㏖/ ㎖, and was significantly higher than in normal subjects (4.567±1.155f㏖/㎖) (P<0.05). The plasma ET-1 concentration (mean±S.D.) in diabetic retinopathy group( 7.15±2.454 f㏖/ml) was significantly elevated than those in otherwise uncomplicated groups (5.348±2.390 f㏖/㎖)(P<0.01). The correlation between any clinical parameters and plasma ET-1 levels in NIDDM was not significant, In conclusion, this study suggest that the elevated levels of ET-1 in diabetic patients may be play a important role in the pathogenesis of diabetic complications.

『Ilbonseogi』(edited A.D.720) was studied to investigate the medical and pharmaceutical exchange among ancient Korea, China and Japan. It seemed that Korean and Chinese traditional medicine was introduced to Japan through Korea. It was also shown in 『Ilbonseogi』 that Koreans who lived in China and Japan during that time seemed to have active medical idea exchange. From various facts indicated in 『Ilbonseogi』, it was believed that Korean and Chinese traditional medicine was the basis for the foundation of Japanese traditional medicine.

신경섭,김원식,손재철,홍승복,최재운,형성민 충북대학교 의과대학 충북대학교 의학연구소 2003 忠北醫大學術誌 Vol.13 No.2

연구목적: Metallo-β-lactamse (MBL)는 carbepenem를 포함하는 대부분의 β-lactam 항균제를 가수분해할 수 있으므로 MBL 생성균의 확산은 이들 균에 의한 감염의 치료에 큰 문제를 야기할 수 있다. 따라서 MBL 생성균에 의한 감염의 확산을 막기 위해 이들 균의 조기 검출이 필요하다. 저자들은 MBL 생성균을 검출할 수 있는 세 가지 방법을 PCR 방법과 비교하여 보았다. 재료 및 방법: Imipenem의 MIC가 8 μg/mL 이상인 50개의 포도당 비발효 그람음성 간균을 대상으로 EDTA-double disk synergy test (EDTA-DDS), Etest MBL, Hodge 변법을 시행하였으며 대조 검사로 IMP-1, VIM-1, VIM-2에 대한 PCR을 시행하였다. 결과: 총 50 균주 중 MBL 생성균은 Pseudomonas aeruginosa 1 균주, Alcaligenens xylosxidans 7 균주 등 8 균주(16%)가 검출되었다. 이들 균주는 모두 VIM-2 형이었으며, EDTA-DDS, Etest MBL은 PCR 방법과 100% 일치하였다. Hodge 변법은 8 MBL 생성균주 중 2 균주를 검출하지 못했다. 결론: 50 균주 중 8 균주가 MBL 생성균이었고 모두 VIM-2 형이었다. Etest MBL은 가격이 비싸 검사실에서는 EDTA-DDS가 적당할 것으로 사료된다. Purpose: Because metallo-β-lactamase (MBL) has activity to hydrolysls against most β-lactam drugs, dissemination of MBL producing bacteria may cause problems of treatment of infection by their microorganisms. Early detection or screening for MBLs will contribute to prevent further spread of resistance. Authors compared three MBL detection methods with PCR for MBLs. Materials and Methods: For 50 isolates of g1ucose nonfermentative gram negative bacilli with reduced susceptability against imipenem (MIC≥8 μg/mL), EDTA-double disk synergy (EDTA-DDS), Etest MBL and modified Hodge test were compared with PCR detection method for MBLs. Results: Among 50 isolates of glucose nonfermentative microorganisms, eight MBL producers including a Pseudomonas aeruginosa and 7 Alcaligenes xylosoxidans were detected. Those isolates were VIM-2 producer. The results of EDTA-DDS and Etest MBL completely agreed with PCR for MBL detection. Two isolates among eight MBL Producers were not detected in modified Hodge test. Conclusion: All of MBL producing bacteria were VIM-2 genotype. In conclusion, EDTA-DDS may be useful method for MBL detection in clinical laboratory due to high cost of Etest MBL strip.

본 논문에서는 인간의 평활 추적안구운동을 모방하는 능동시각시스템(active vision system)을 구현하였다. 평활 추적 안구운동을 모방하는 능동시각시스템을 구현하기 위해 인간의 안구운동 중에 관찰되는 신경생리학적인 특징들을 이해하고, 다양한 안구운동 중에서 평활 추적안구운동 중에 관찰되는 중측관자(medial temporal) 세포의 역할을 자기조직화 형상지도(self-organizing feature map)와 승자독점(winner take all)을 이용하여 구현하였다. 회전속도계 궤환 모델(tachometer feedback model)로 중상측관자(medial superior temporal) 세포의 역할을 모델하였다. 그리고 인공망막칩으로 인공 안구를 구성하고 형상기억합금 구동기(actuator)를 이용하여 인공 안근육을 구성하여, 빛의 밝기 변화인 윤곽(edge) 정보에 반응하는 인공 안구모형을 제작하였으며, 실험을 통하여 시스템의 동작성능을 보였다. In this paper, we proposed a model of smooth pursuit eye movement, and developed a human-like active vision system using a retina chip and a shape memory alloy actuator. The model of smooth pursuit eye movement is to imitate the role of MT and MST area of human brain in smooth pursuit eye movements. We fabricated the 8×8 retina chip for the edge detection. The developed retina chip is an image sensor to extract edge information and the shape memory alloy actuator is a driver to imitate the role of eye muscles to follow a moving object.
