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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

The Ni (OH)₂ nanoparticles with average diameter of 50 nm were synthesized by hydrolyzing nickel acetate with water, and were dispersed in the distilled water to prepare the coating solution. The electrodes for supercapacitor were prepared by dip-coating the coating solution on the Ni-foam. The electrodes heat-treated at several temperatures showed the highest specific capacitance, 160 F/g, at 250℃. It can be explained that the Ni(OH)₂ particles heat-treated at 100 and 200℃ on the electrodes contained the impurities such as acetate groups in the pores, and resulted in low specific surface areas. However, as the calcination temperature increases. the impurities incorporated in the pores are removed at 250℃, and thus, the particles on the electrodes show the highest specific surface area (177 ㎡/g).

본 시험은 크릴 분말의 사료적 특성을 조사하고, 산란계 사료에 첨가하였을 때 계란의 생산성과 품질을 비교하기 위하여 수해하였다. 크릴 분말을 산란계 사료에 0, 1 및 2% 수준으로 첨가하여 216수에 6주간 사양시험을 실시하였다. 크릴분말의 일반성분은 수분 8.25%, 조단백질 50.52%, 조지방 16.67%, 조회분 15.72%로 단백질과 지방이 높은 동물성 사료원료였다. 그리고 무기질(15.72%), astaxanthin (10ppm) 및 콜레스테롤 함량 (780ppm) 또한 많았다. 산란율, 연파란율, 일일사료섭취량 및 난중은 처리간에 유의적인 차이가 없었다. 황고 및 난황색도는 크릴의 첨가수준이 높을수록 유의적으로 높아 산란계의 난질을 향상시키는 첨가제로서의 가능성을 보였다. 이상의 결과를 볼 때 크릴 분말은 단백질과 지방이 높은 동물성 사료이며, 산란계에서 천연착색제로의 가능성을 보였다. This experiment was conducted to evaluate the chemical composition of Antarctic Krill(Euphausia superba Dana) meal as feed, and to investigate the effect of its supplementation on productivity and egg quality of laying hen. A total of 216 layers at the age 43 weeks in commercial cage were fed for 6 weeks with 3 different diets containing 0, 1, and 2% Krill meal (KM). The chemical composition of KM was consisted of moisture 8.25%, crude protein 50.52%, crude fat 16.67%, curde ash 15.72%, indicating that KM contains large amount of protein and fat. Krill meal also contains large amounts of mineral(15.72%), astaxanthin(10ppm) and cholesterol(780ppm). No differences were found in egg production, broken and soft eggs, and feed intake among treatments. Dietary supplementation of KM resulted in increased egg yolk height(6.1㎜) and yolk color (2) compared with those of control, suggesting that KM can be used as a feed additive for yolk quality improvement. According to the results of this study, Krill meal can be supplemented in laying hen diets as protein and fat sources, and natural coloring pigment.

The purpose of this study was to compare the amount of calcium fluoride deposited on the enamel and dentin surface and to obtain information on the morphological change and crystallographic details of mineral deposition after 12,000ppm APF application in vitro. The bovine enamel and dentin blocks were randomly assigned to eight groups according to artificial caries lesion formation and difference of fluoride application time. The fluoride concentration and morphological characteristics on the treated enamel and dentin surface were investigated by using fluoride quantitative analysis and SEM. The powdered enamel and dentin of the intact bovine incisors were prepared for the X-ray diffraction analysis. The following results were obtained. 1. The amounts of KOH-soluble fluoride on the carious enamel and dentin surface after 24h APF application were higher than after only 5min APF application(P<0.05), but in the case of the sound enamel and dentin surface were similar after 5min and 24h application (P>0.05). The fluoride content was highly increased in the carious dentin as compared with sound dentin after APF application(P<0.05). 2. The caruous enamel surface after APF application, the demineralized enamel surface were recovered a more dense enamel surface and precipitation of crystal was observed a distintive surface layer of spherical globules of about 1 m diameter. In the case of the fluorided carious dentin surface, precipitation of calcium fluoride-like material was deposited both inside the dentinal tubules as well as in the intertubular regions. 3. The crystallographic structure of powdered enamel and dentin after 24h APF application had large crystallities of apatite and CaF2 diffraction peaks in the enamel as compared with dentin. The diffraction data collected from the 27.50-29.50(2) angular range of the powdered enamel, the (105) apatite, (225) apatite and (111) CaF2 peaks of the enamel crystallities were detected after 24h APF application.

Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.
