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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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.

Abstract This study is to find out the difference of mental health and school adaptation according to internet poisoning of junior and senior high school students, and the studyresults are as follows. First, it was found that the internet poisoning level of junior high school students is higher in all subordinate factors than that of senior high school. Second, regarding the difference of self among mental health according to inter-net poisoning level of junior and senior high school students, it was found that the higher the internet poisoning level, that is, the closer to internet poisoning stu-dents, the more problems were in emotion sell, learning self, coping self, body self. As to the difference among mental health, it was found the more the students used internet, the higher the degree of affect, neurosis, somaticization, acting, etc. Lastly, regarding the difference of social support among mental health, it was found that the lower the internet poisoning level, the more the students think that they receive more support from their families, friends and relatives. Third, in the difference of school adaptation according to internet poisoning level of junior and senior high school students, it was found that the higher the internet-poisoning level of students, the more difficult were they in adapting themselves to school life. Especially, the higher the internet poisoning level, the more difficult were they in all the subordinate factors of school adaptation. So, it was revealed that the more exposed to internet students, the more student failed in adapting to school where they stayed for the longest time, In conclusion, it was found that there was a difference in mental health and school adaptation according to internet poisoning level, and the closer to internet poisoning, the more difficulties they suffer in mental health and school adaptation. Therefore, it seems urgent to develop treatment or a prevention program for them.

To investigate nutrient dynamics of the lake and fish community, both water and fish samples were collected at three different areas (dam site, upper inflowing and downstream of lake outfow) for one year from Sep.2004 to Aug.2005 During the experimental periods, mean concentration of chl, a in epilimnetic layer (0-5m) was 18.5mg^(-3) and transparency ranged from 0.3m to 2.4m, respectively. In nutrient, mean concentrations of TP and TN were 111 mgP m^(-3) and 4.4 mgN L^(-1), respectively. Based on the water quality standard suggested by U.S.EPA(*1976), the trophic state of Lake Doam was classified as eutrophic state. Total number of fish collected in Lake Doam was 9,600 indiveduals in 26 species of 6 family. Sixteen of Korean endemic soecies including H. mylodon, A. signifer, P. tenuicorpa occurred. O. mykiss as introduced fish was also found in Lake Doam. Dominant and subdominant species were P. herzi and Z. platypus that took about 34.6% and 22.5% of total fish composition, respectively. Six species including A. signifer. P. tenuicorpa. and R. kumgangensis were rare in Lake Doam. Pelagic typw of figh commonly occurred at upper regions, whereas benthic type was mainly domenated at downstream area. Therefore, pollution source inflowed from the upper regions did not seriously affect downstream area (Songcheon water system) due to the role of dam as pollutant barrier. In addition high appearance of Comat type of fish that si hybrid between gold fish (C.auratus) and C. auratus was found in the lake, It was unclear the reasons that high prorortion of mutant species apperared in the lake. Further more researches are required in this area.

이무열,방효원,엄대용,이상돈 중앙대학교 의과대학 의과학연구소 1992 中央醫大誌 Vol.17 No.4
In order to observe the effects of ascorbate on the background current in pyloric circular smooth muscle cells, caffeine of which action was fairly clarified, was used to induce the current systems. To block all of the known currents, various blocking agents were added in the external bathing solution. A part of pyloric circular muscle tissue was excised out, and enzymatic isolation technique was used to obtain Ca^2+ -tolerant single circular muscle cells. The whole cell mode of patch-clamp experiment was conducted. The results were as follows : 1. Ascorbate induced the increase of inward currents in the hyperpolarized potential ranges, and quite a large increase of outward currents in the depolarized ranges. 2. Caffeine also induced similar results, but the magnitude of outward current was smaller than that of assorbate in the depolarized ranges. 3. These phenomena were disappeared by addition of the anion channel blocker. 4. Replacement of external NaCl with NMG·Cl was rarely affected the effects of ascorbate and and caffeine. But the effects of ascorbate and caffeine were almost abolished when sxternal Cl^- was substituted for aspartate. These results suggested that ascorbate affected chloride current which thought as a component of the background currents in the pyloric circular smooth muscle cells.
