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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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: 만성 B형 간염의 치료 중 발생하는 약제 내성 변이종은 임상적으로는 치료 중 음전되었던 혈청 HBV DNA가 다시 양전되는 viral breakthrough 로 진단할 수 있다. 현재 약제 내성 변이종이 발생했을 경우라도 라미부딘 치료를 계속 유지하는 것을 권장하고 있으나, viral breakthrough 발생 예들의 장기적 임상경과가 아직도 불명확하여 이것을 일반화하기는 어려운 상황이다. 이에 라미부딘 사용 중 viral breakthrough 가 발생한 예들을 대상으로 그 임상경과를 알아보고자 하였다. 대상과 방법: 9개월 이상 라미부딘을 투약한 만성 B형 간염 환자로 viral breakthrough가 발생한 74명을 대상으로 하였다(남/여 54/20, 평균연령 42세). Viral breakthrough 후 혈청 ALT치, 총 빌리루빈치, HBV DNA 역가, HBeAg, anti-HBe를 정기적으로 검사하면서 임상경과를 관찰하였다. Viral breakthrough 후 라미부딘의 투약기간은 평균 13개 월(1-41개월)이었다. 결과: Viral breakthrough 발생후 혈청 ALT치가 정상으로 유지되었던 환자는 8예(11%)에 불과했고 나머지 66예(89%)에서는 ALT치가 증가하였으며, 이중 30예(41%)에서 급성 악화(ALT 정상 상한치의 5배 이상 상승)를 보였다. 급성악화는 viral breakthrough 후 3개월 내에 19예 (63%)에서 발생하여 3개월 내에 발생한 예가 많았으나 12개월 이상 지나서 나타나는 예도 약 20%에서 있었다. 비대상성 악화는 6예에서 관찰되었다. Viral breakthrough 후 급성악화가 일어난 예와 없었던 예의 비교에서 급성악화를 예측할 수 있는 인자는 발견할 수 없었다. Viral breakthrough 후 발견할 수 없었다. Viral breakthrough 후 HBeAg이 음전된 예는 8예(11%)였으나 그 임상경과는 양호하지 않았다. 결론: 만성 B형 간염 환자 에서 라미부딘 투여 중 발생한 viral breakthrough 예 중 상당수에서 급성악화가 발생하였으며, HBeAg 이 소실되더라도 그 임상경과는 양호하지만은 않았다. Viral breakthrough 발생 후 주의 깊은 임상경과 의 관찰이 요구되며, 앞으로 viral breakthrough 후 급성악화 예에 대한 대규모 연구와 적절한 치료방향의 제시가 이루어져야 할 것으로 생각된다. Background/Aims: Long-term lamivudine therapy can induce the emergence of lamivudine resistant hepatitis B virus (HBV) mutants. Clinically emergence of the mutant is expressed by the reappearance of disappeared HBV DNA in serum. Continued lamivudine treatment has been usually recommended in cases of viral breakthrough. However, the clinical outcome in patients with viral breakthrough is not clear. The aim of this study was to investigate the clinical course of chronic hepatitis B patients after viral breakthrough during lamivudine therapy. Methods: A total of 74 patients with chronic hepatitis B who showed viral breakthrough after at least 6 months of lamivudine treatment were included in this study. They had positive HBeAg and HBV DNA before treatment. The median follow-up duration after breakthrough was 13 months. Results: After viral breakthrough, only 8 patients (11%) maintained normal ALT levels and 66 patients (89%) showed elevation of ALT. 30 patients (41%) showed acute exacerbation of hepatitis (ALT increase over five-times upper normal limit). These acute exacerbations occurred within three months after breakthrough in 19 patients (63%). In the cases of acute exacerbation, 6 patients showed decompensated progression such as elevation of serum total bilirubin. One of them died of hepatic failure. A predictive factor for acute exacerbation was not found. HBeAg seroconversion occurred in 8 patients after viral breakthrough but their clinical course was highly variable. Conclusions: Chronic hepatitis B patients who had viral breakthrough during lamivudine therapy should be followed carefully and regularly in mind of potential clinical deterioration. New strategies are needed to manage the cases of acute exacerbation after viral breakthrough.(Korean J Hepatol 2002;8:389-396)

Phaffia rhodozyma 변이주를 이용한 Astaxanthin 생산에 관한 연구

도영훈,백남수 김영만 한경대학교 2005 論文集 Vol.37 No.-

Phaffia rhodozyma IFO 1012901 was treated with mutagenic agent NTG(N-methly-N'-nitro-N-nitrosoguanine) and mutant strain Phaffia rhodozyma MG5150 was isolated. Phaffia rhodozyma MG 5150 showed 3.7 times higher in astaxanthin production than that of parental strain. In increasing the high production of astaxanthin from Phaffia rhodozyma MG5150, the effect of various carbon sources, nitrogen sources, cationic metal ions, the initial pH of the medium and agitation speed were investigated. The most effective carbon and nitrogen sources were found to be glucose 15% and (NH_(4))_(2)SO_(4) 5% respectively. None of the cationic metal ions examined had any detectable stimulating effect on astaxanthin production except Zn^(+2) ion. The initial optimum pH for astaxanthin production ranged from 4.5-5.0 and agitation speed was most effective at 250 rpm. In the jar fermentor experiments under optimal culture conditions, the accumulation of astaxanthin reached about 5.78㎎/㎖ after 96 hours of cultivation and the level decreased for a further cultivation.

임영식,이홍재,이도진,허종수,손보균,조주식 한국환경과학회 2002 한국환경과학회지 Vol.11 No.12

This study was carried out to evaluate the pollutant removal efficiencies of the advanced drinking water treatment using ozonation process. For raw water, Nakdong River was used. By conducting batch test of ozonation efficiencies of the ozonation were 94 to 92%, respectively. Removal efficiencies of single VOC compound or mixed VOC compounds in the raw water were 80% to 90% by the ozonation with 2 mg/ℓ dosage and 10 minutes contact time. Removal efficiencies of ABS by the ozonation with 1 mg/ℓ, 3 mg/ℓ dosage and 20 minutes contact time were 83% to 96%, respectively. Almost 67% of chlorophyll-a at the concentration of 38.㎍/ℓ was removed by ozonation at ozone dosage of 1mg/ℓ for 20 min. considering the efficiency of ozone utilization and water treatment, the most effective ozonation could be obtained with high ozone dosage and short and short contact time.

High density plasma deposition system was organized using electron cyclotron resonance source, and its plasma properties were measured by using the Langmuir probe method. The ECR microwave plasma conditions could be controlled by means of mass flow controller and ECR microwave power according to the vacuum pressure of 2.3×10^-5 Torr to 5.2×10^-2 Torr. The ion density was increased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The electron temperatures were decreased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The estimated plasma potential was from 27.0V to 31.5V

레크리에이션의 社會學的 硏究動向

安永弼,金有洙,孔庚鎬,都根鎬 東亞大學校 附設 스포츠科學硏究所 1993 스포츠科學硏究論文集 Vol.11 No.-

The recreation research held in Korea is mostly based on a social survey method, empolying a theoretical approach to recreation's principles. In the US and Canada, however, the research is more practical and academical, including sociology, psychology, economics, urban engineering, and ecology. A sociological approach to recreation was initiated by T.B.Vebren in 1899. His essential contribution was "The theory of leisure class : an economic study in the evolution of institutions." The so-called leisure sociology supported by experimental data came into being in the 1920s-1930s. Up to now, then, the sociological tendencies in recreation research show the increasing number and areas of applied studies, focused on scientific and contributing to the solution of actual problems of everyday life.
