Indicators of environmental conditions qualitatively and quantitatively describe the state of the environment and natural resources, and the OECD (Organization for Economic Cooperation and Development) has initiated and suggested AEIs (Agri-Environmental Indicators) to assess trends over time of the effects of agriculture on the environment and the effectiveness and efficiency of agricultural and environmental policy measures since 1990's. This study aims to develop the state indicators of water quality for agricultural water, surface and groundwater, to evaluate the environmental impacts of agricultural activities and policies by qualifying the environmental levels of a nation. Status indicators were calculated according to the agricultural water quality standards of OECD and Korea, and their trends were analyzed over time. Particularly, nitrate ($NO_3{^-}$) status indicators of ground water in 2013 were significantly lower than the ones in 2000. Overall, the water quality indicators of surface water in 2013 were higher than the ones in 2012, except for pH and DO. The groundwater quality indicators in 2013 were lower than those of previous years. The optimal management indicators were calculated to assess agricultural surface water and groundwater quality. The findings of this study indicated that the state indicators could play a significant role to establish policies and procedures for managing and conserving water resources. This study also discussed water pollution caused by agricultural and industrial effluents.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

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.

목적 : 양성 갑상선 결절 환자에서의 PEI의 치료효과 및 부작용을 알아보고자 하였다. 방법 : 양성 갑상선 결절 환자 88명을 대상으로 초음파 소견에 따라 낭종성 결절, 복합성 결절, 고형성 결절 등 세 그룹으로 분류후 전체 및 각각에 대한 PEI의 치료효과 및 부작용을 조사하였다. 결과 : 양성 갑상선 결절 환자 88명을 PEI로 치료후 결절의 크기가 50%이상 감소한 경우는 전체 환자중 77.2%이었고 각 결절별로 살펴보면 고형성 결절에서 52.6%, 복합성 결절에서 72.4%, 낭종성 결절은 92.5%이었다. 부작용은 동통, 결절내 출혈, 감염, 결절의 누출등이 있었으나 대부분 무증상이었다. 결론 : PEI는 양성 갑상선 결절 환자증 적응증을 잘 살펴 고려해 볼 수 있는 치료법이라 생각되며 특히 낭종성 결절 환자에서 주사기에 의한 흡인후에 재발한 경우 일차적인 치료로 PEI를 고려해 볼 수 있겠다. Ultrasonography(US)-guided percutaneous ethanol injection (PEI) has been performed for the treatment of autonomous functioning thyroid nodules, thyroid cysts, & cold thyroid nodules. The author studied the efficacy of PEI in the treatment of benign cold thyroid nodules both solid and cystic (complex & pure). Eighty-eight euthyroid outpatients (age:44.2±13.9years, 75 women and 13 men) with benign cold thyroid nodules or simple thyroid cysts (69 with a single nodule and 19 with a prominent nodule within multinodular goiter) were includied in this study. After PEI, each subtype of thyroid nodules was divided into three groups in according to volume reduction complete response (90% or more of volume reduction), partial response (50% or more of reducton but below 90%), and failure (below 50% or increase in size) group. Overall response rates of PEI for benign thyroid nodules were complete 45(51.1%), partial 23(26.1%), failure 20(22.7%). In 20 cold solid nodules, complete response was observed in 6(30.0%), partial response in 5(25.0%), and failure in 9(45.0%). In 28 complex cysts, complete response was observed in 8(28.6%), partial response in 12 (42.9%), and failure in 8(28.6%). In 40 pure cysts, complete response was observed in 31(77.5%), partial response in 6 (15.0%), and failure in 3 (7.5%). Side effects comprised pain 8 (9.2%), intranodular bleeding 13 (14.6%), extracapsular leakage 1(1.1%), infection 1 (1.1%), increased size l(1.1%), and none 64(72.7%). PEI may prove a safe & effective tool for the therapy of cold thyroid nodules in selected cases and may be the treatment of choice of recurrent thyroid cysts. However, further investigation involving a larger number of patients and a longer follow-up is needed.

김현진,정효균,홍우정,김군순,조영석,김도희,채수흥,구본정,송민호,노흥규,김영건 충남대학교 의과대학 지역사회의학연구소 2001 충남의대잡지 Vol.28 No.1

Background : ICAM-1 act as one of major adhesion molecules in the atherosclerotic lesion. ICAM-1 expression is mainly regulated at the level of transcription and depend on IFN-γ signal transduction pathway in which the STAT1 transcrption factor is a critical intermediate. IFN-γreceptor not only initiates tyrosine 701 phosphorylation of STAT1 by Jak1 and Jak2, but also phosphorylates serine 727 through the activation of Raf-1/MAP kinases. HMG-CoA reductase inhibitors have anti-atherosclertic effects, beyond normalization of hypercholesterolemia, by directly acting on endothelial cells, macrophages and vascular smooth muscle cells. HMG-CoA reductase inhibitors suppress the synthesis of isoprenoid intermediates such as geranylgeranyl-pyrophosphate or farnesylpyrophosphate. These effects results inhibitors suppress the synthesis of isoprenoid intermediates such as geranylgeranyl-pyrophosphate or farnesylpyrophosphate. These effects results inhibition posttranslational farnesylation and geranyl-geranylation processing of small GTP-binding preoteins and inhibition of normal signaling activities. Method : We made several 5'-deletion constructs of rat ICAM-1 promoter and analyzed the promoter activities by measuring the luciferase activity after transfection into ECV304 cells and smooth muscle cells. We checked the level of total and phosphorylated STAT1 protein by immunoblot analysis using specific antibodies. Results : Lovastatin inhibits IFN-γ-induced ICAM-1 gene expression in the ECV304cell. The cells pretreated with PD98059, MEKK inhibitor showed significantly low ICAM-1 RNA induction with IFN-γ stimulatio. IFN-γ induced phosphorylation of tyrosine 701 was not significantly changed by the pretreatment of lovastatin. But lovastatin suppresses IFN-γ-induced phosphorylation of ERK1/ERK2 which are responsible for the seine 727 phosphorylation in STAT1. Conclusion : We showed that HMG-CoA reductase inhibitors, lovastatin, suppresses IFN-γ mediated ICAM-1 gene expression through the inhibition of transcription. HMG-CoA reductase inhibitor suppresses IFN-γ-induced phosphorylation of serine 727 in STAT1 through the modulation of MAP kinases.
