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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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 연구에서는 고무제품의 수치 안정성과 성능유지에 직접적으로 영향을 미치는 중요한 특성 중 하나인 온도변화에 따른 고무재료의 경도변화를 고찰하였다. 새롭게 제작된 International Rubber Hardness Degree(IRHD, Normal type) 경도측정 시험기를 사용하여 미충전된 NR과 SBR시편의 여러 온도에서 경도변화를 측정하였으며 Young`s modulus 값과 비교하였다. NR과 SBR 모두 유리전이온도 근처에서 경도와 Young`s modulus의 급격한 변화를 보였다. 온도가 증가함에 따라 경도와 Young`s modulus 값이 증가하는 경향을 보였으며 이는 분자의 운동성과 엔트로피 영향으로 해석할 수 있다. 카본블랙과 실리카가 충전된 NR과 SBR의 경우 충전제의 함량이 증가함에 따라 경도에 미치는 온도의 영향이 감소함을 관찰하였다. Hardness of rubbery materials, which is important for dimensional stability and product performance, was investigated upon temperature change in this study. A newly developed IRHD (International Rubber Hardness Degree) tester was used to measure the hardness changes of NR and SBR specimens at various temperatures and the hardness values were compared with the Young`s modulus. The hardness and Young`s modulus of NR and SBR showed an abrupt change near the glass transition temperatures. The hardness and Young`s modulus were increased by increasing temperature due to the increased random chain conformation of molecules. The effect of temperature on hardness and Young`s modulus of NR and SBR specimens filled with carbon black and silica was decreased by increasing filler content.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

음이온에 의한 토마토 뿌리조직 마이크로솜 H^+-ATPase 활성 저해

신대섭,조광현,김영기 충북대학교 첨단원예기술개발연구센터 2000 연구보고서 Vol.5 No.-

식물 뿌리세포의원형질막 및 액포막에 위치하는 H+-ATPase들은 세포의 여러 가지 생리활성에 중요한 역할을 수행한다. H+-ATPase의 생리활성 특성을 조사하기 위하여 토마토 뿌리조직으로부터 마이크로솜을 분리하고, H+-ATPase 활성에 미치는 음이온의 효과를 조사하였다. 다양한 종류의 음이온들이 H+-ATPase의 활성을 저해함을 확인하였으며, 이들 중 특히 효소의 저해정도가 다른 citrate와 인산을 선택하여 작용특성을 조사하였다. Citrate에 의한 ATPase 활성저해는 3mM 이상에서 나타났고, 20 mM citrate는 활성을 50-60% 저해하였다. 그러나, citrate,의 저해효과는 MG2+의 농도를 증가시킬수록 감소하여, citrate에 의해 저해된 ATPase 활성은 Mg2+에 의해 회복되는 것으로 나타났다. 즉, 7 mM Mg2+을 첨가하였을 때, citrate에 의한 활성저해는 관측되지 않았고 ATPase 활성은 대조활성과 비슷한 수준으로 회복하였다. 이러한 결과는 citrate가 Mg2+을 chelation함으로써 H+-ATPase의 활성을 저해하기 때문이다. 한편, 인산에 의한 ATPase 활성저해는 3mM 이상의 농도에서 나타났고, 30 mM 인산은 ATPase의 활성을 50% 저해하였다. 인산에 의해서 저해된 ATPase의 활성은 MG2+의 농도증가에 의해 회복되지 않아, 인산에 의한 저해효과는 Mg2+과 무관하였다. H+-ATPases located on plasma and vacuolar membranes play major roles in various cellular physiological processes. In order to investigate the physiological roles of H+-ATPases, microsomes were prepared from tomato roots and the effects of various anions were measured on the activities of H+-ATPases. H+-ATPase was inhibited by various anions. Citrate and phosphate were chosen to investigate detailed inhibitory mechanisms on ATPases since they showed different levels of inhibition. Inhibitory effect of citrate was observed at the concentrations above 3 mM. when 20 mM citrate was added, the H+-ATPase activity was decreased by 50-60%. However, the inhibitory effect of citrate was decreased by increasing the concentration of Mg2+. The citrate-induced inhibited activity was recovered by the addition of Mg2+. Addition of 7 mM Mg2+ completely removed the inhibitory effect of citrate and the activity recovered to the level of the control experiment. These results imply that citrate chelates Mg2+ and thus inhibits H+-ATPases. Meanwhile, the inhibitory effect of phosphate was observed at the concentration above 3 mM and the activity was decreased by 50% in the presence of 30 mM phosphate. Further addition of Mg2+ showed no recovery on the activity. These results imply that the inhibitory effect of phosphate is not dependent upon the concentration of Mg2+.
