This study examined the moderating effects of parental monitoring and peer pressure on the relationship between moral disengagement and cyberbullying. A total 312 of male and female middle school students participated in the study. The data were analyzed by means of negative binomial poisson regression, because cyberbullying in this study was a estimate closed to frequency and revealed over-dispersion. The results were as follow. First, moral disengagement and peer pressure affected on cyberbullying significantly. The higher moral disengagement and peer pressure were, the more cyberbullying behavior was. Parental monitoring didn’t affect on cyberbullying significantly. Second, parental monitoring had moderating effect in the relationship between moral disengagement and cyberbullying. Parental monitoring served as a protective factor to reduce cyberbullying behavior when at lower level than at higher level of moral disengagement. Third, peer pressure had moderating effect in the relationship between moral disengagement and cyberbullying. Peer pressure served as a risk factor to increase cyberbullying behavior when at lower level than at higher level of moral disengagement. Based on the results of this study, it was suggested that the effects of parental monitoring and peer pressure on cyberbullying were different from those of offline bullying, and needed to include other interventions for parental monitoring and peer pressure depending on the level of moral disengagement. 본 연구는 도덕적 이탈이 사이버불링에 미치는 영향을 알아보고, 도덕적 이탈과 사이버불링의 관계에서 부모감독과 또래압력의 조절효과를 알아보았다. 질문지 조사를 통해 312명의 남녀 중학생 자료를 수집하였다. 종속변인인 사이버불링은 일반적인 평정척도보다는 합산 평정척도인 빈도에 가까운 척도이어서 포아송 회귀분석을 하였고, 포아송 회귀분석을 한 결과 과대산포가 나타나서 음이항 분포를 가정한 회귀분석을 하였다. 분석 결과는 첫째, 도덕적 이탈은 사이버불링에 유의미한 영향을 미쳤으며, 도덕적 이탈이 높을수록 사이버불링 가해행동을 많이 하는 것으로 나타났다. 부모감독은 사이버불링에 유의미한 영향을 미치지 않았으며, 또래압력은 유의미한 영향을 미쳐서 또래압력이 높을수록 사이버불링 가해행동을 많이 하는 것으로 나타났다. 둘째, 도덕적 이탈과 사이버불링의 관계에서 부모감독의 조절효과는 유의미하게 나타났는데, 도덕적 이탈 수준이 높을 때보다 낮을 때 부모감독이 사이버불링 가해행동을 감소시키는 보호요인 역할을 하였다. 셋째, 도덕적 이탈과 사이버불링의 관계에서 또래압력의 조절효과는 유의미하게 나타났는데, 도덕적 이탈 수준이 높을 때보다 낮을 때 또래압력이 사이버불링 가해행동을 증가시키는 위험요인 역할을 하였다. 이러한 연구결과에 기초해 사이버불링에 미치는 부모감독, 또래압력의 영향이 오프라인 불링에서와는 다른 양상을 갖을 가능성과, 사이버불링 방지를 위해 도덕적 이탈 수준에 따라 부모감독, 또래압력의 차별적 개입 방안이 필요함을 논의하였다.

N/A Background : There is an individual variation in the hepatic injuries following alcohol abuse, which may be partly caused by the diverse activities of enzymes participating in the degradation of alcohol. Polymorphism of cytochrome P450 2E1 (CYP2E1) gene has been reported to affect the degradating activity of the enzyme, which may be eventually associated with the severity of alcoholic liver disease. In this study we were to evaluate the effects of genetic polymorphism of CYP2E1 on hepatocellular injury or fibrosis. Methods : We analyzed the relationship of CYP2E1 genotypes to the biochemical and clinical characteristics as well as TGFβ1 expressions in a total of 33 patients (M:F=32:1) with advanced alcoholic liver cirrhosis. CYP2E1 genotypes were determined by RFLP using RsaI and PstI. The amounts of serum TGFβ1 were measured by ELISA (TGFβ1 ELISA system, Promega, USA). Results : Out of 33, 23 (70%) had the CYP2E1 of genotype A and all of the remaining 10 (30%) were type B; there was no one who had type C. The serum albumin levels of patients with type A of CYP2E1 gene were lower than those with type B (p=0.01); the Child-Pugh scores were also higher in patients with type A than B (p=0.03). However, there was no difference between the two groups in the serum AST, ALT, γ-GTP and bilirubin levels. The patients expressed similar amount of serum TGFβ1 regardless of their CYP2E1 genotypes. Conclusion : Our data indicates that the most common genotype of CYP2E1 is type A (70%) in patients with advanced alcoholic liver cirrhosis in Korea. It is also suggested that patients with genotype A of CYP2E1 may be associated with more advanced alcoholic liver cirrhosis compared to those with type B.(Korean J Med 60:222-227, 2001)

Paraquat, a very potent herbicide, has produced many fatalities through indiscriminate usage and suicides. It is known that with ingestion of more than one mouthful of 20% paraquat, death usually occurs by pulmonary fibrosis. We experienced two cases of successful outcome in patients with paraquat poisoning complicated with pulmonary fibrosis through active, intensive treatment from the early phase after ingestion. They swallowed one to two mouthfuls of the 20% commercial paraquat, and received hemoperfusion within 2-3 hours after ingestion. Then, combination therapy with steroid, vitamin C, D-penicillamine, allopurinol, colchicine was administered from the early phase. They showed moderate to severe hypoxemia and pulmonary fibrosis on chest HRCT during hospital course, but recovered from hypoxemia and remained very well on follow up over 3 months and 12 months after ingestion, respectively. We report these cases with literature review on treatment and prognosis of paraquat poisoning. (Korean J Med 60:490-495, 2001)

N/A Background : In Korea, paraquat accounts for most of fatal poisoning with 500 or more deaths per year. It has been known that patients who ingested more than 1/2 mouthful of 20% concentrate paraquat usually die of multiorgan failure and pulmonary fibrosis. But the effect of charcoal hemoperfusion which can enhance elimination of paraquat remains controversial. Because acute paraquat poisoning is also characterized by multiorgan failure including kidney and marked rebound in plasma paraquat level after hemoperfusion, Continuous veon-venous hemofiltration(CVVH) may have theoretical benefits in the treatment of paraquat poisoning. So we evaluated the effect of early charcoal hemoperfusion and prophylactic CVVH after hemoperfusion in patients with paraquat poisoning. Methods : There were 80 patients with paraquat poisoning admitted within 24 hours after ingestion (August 1996 - March 1998). All of them were treated with hemoperfusion (duration of hemoperfusion, 6.4±3.0 hours) within 24 hours of ingestion. The amount of ingestion was 2.1±1.0 mouthful (as 20% concentrate) and 78 (98%) were urine sodium dithionite test positive which is a poor prognosis factor. Forty-four patients received hemoperfusion only and 36 were followed by CVVH (duration, 50.4±20.9 hours; ultrafiltration volume, 33.8±3.9 L/day) after hemoperfusion. Results : There was no difference between the hemoperfusion group and hemoperfusion+CVVH group in age, sex, initial serum creatinine, arterial oxygen saturation, severity of poisoning (as assessed by serum paraquat level determined by HPLC and amount of ingestion), or in the time elapsed from ingestion to the beginning of hemoperfusion. The total mortality was 65% (52/80) with no difference between the hemoperfusion group (64%, 28/44) and hemoperfusion+CVVH group (67%, 24/36). The mortality according to amount of ingestion was as follows: 〈 1 mouthful, 0% (0/5); 1 mouthful, 53% (8/15); 2 mouthful, 65% (11/17); ≥ 3 mouthful, 82% (27/33); unknown, 60% (6/10). Conclusion : Early hemoperfusion can be effective in reducing mortality in patients who ingest less than 2 mouthful. Even though prophylactic CVVH after hemoperfusion has no additional benefit in reducing mortality in paraquat poisoning, it prolonged the time to death after ingestion.(Korean J Med 59:651-656, 2000)

목적: 말기 신부전 환자에서 에리스로포이에틴 (epoietin)을 주 2-3회 피하 주사 하는 방법은 자주 주사해야 하는 번거로움 뿐만 아니라 주사할 때마다 매번 통증이 발생하기 때문에, 고용량의 epoetin를 일시에 투여하여 투여 간격을 늘리는 주 1회 요법이 시도되고 있다. 본 연구에서는 혈액투석을 받는 말기 신부전 환자에서 고용량 epoetin alfa의 주 1회 요법을 주 2-3회 피하 투여와 비교하여 그 효과와 안전성을 시험하였다. 방법: Epoetin을 피하 투여 중인 혈액투석 환자 83명을 주 1회 투여군 (n=44) 또는 주 2-3회 투여군 (대조군, n=39)으로 무작위 분류하였다. 각 군의 환자는 총 10회 방문 (스크리닝 2회, 이후 8회)하여 12주간 치료 반응을 관찰하였다. 주 1회 투여군은 10,000 IU의 주사를 사용하여 정해진 용량의 epoetin alfa를 주 1회 투여하고, 대조군은 4,000 IU의 주사를 사용하여 정해진 용량의 epoetin alfa를 주 2-3회로 나누어 투여하고 혈색소 수치가 9.0-12.0 g/dL 유지하도록 용량을 조정하였다. 결과: 투여 시작시, 4주, 8주, 12주에 혈색소는 주 1회 투여군은 10.7, 11.1, 11.3, 11.0 g/dL, 대조군은 10.5, 11.3, 11.5, 11.3 g/dL로 유의한 차이가 없었다. 투여 시작시, 4, 8, 12주의 epoetin alfa의 평균 투여량은 주 1회 투여군은 142.8, 123.0, 116.7, 112.3 IU/kg/week이며, 대조군 128.4, 119.3, 103.5, 101.2 IU/kg/week으로서 주 1회 투여군에서 다소 많은 경향을 보였으나 통계적인 유의성은 없었다. Epoetin alfa의 용량을 증가시키지 않고 혈색소 수치가 유지된 환자의 비율도 주 1회 투여군 95.5%, 대조군 92.3%으로 차이가 없었다. 결론: 고용량 epoetin alfa의 주 1회 요법은 목표 혈색소를 유지하는데 있어 epoetin alfa를 2-3회 나누어 투여하는 방법과 효과와 안정성 면에서 비슷하였다. 따라서 안정적인 혈액투석 환자에서 고용량 epoetin alfa의 주 1회 요법이 효과적인 방법으로 생각된다. Purpose: Compared with the practice of administrating subcutaneous erythropoietin injection two or three times a week in end-stage renal failure, a weekly administration reduces the frequency of injection and the workload in renal units. We investigated whether subcutaneous epoetin alfa administered weekly was as effective as the same weekly dosage given in two or three divided doses. Methods: Eighty-three patients were randomized to treatment with subcutaneous epoetin alfa either once a week (n=44), or to their original dosage two or three times a week (control, n=39) for 12 weeks. If hemoglobin was out of range (9.0-12.0 g/dL), the dosage was changed. Results: Mean hemoglobin levels at randomization and after 4, 8 and 12 weeks were 10.7, 11.1, 11.3 and 11.0 g/dL, respectively, in the once weekly group compared with 10.5, 11.3, 11.5 and 11.3 g/dL, respectively, in the control group. The mean weekly epoetin alfa dosage at randomization and after 4, 8 and 12 weeks were 142.8, 123.0, 116.7 and 112.3 IU/kg, respectively, in the once-a-week group compared with 128.4, 119.3, 103.5 and 101.2 IU/kg, respectively, in the control group. No statistically significant differences between the groups were apparent in changes in hemoglobin levels or epoetin alfa dosages at week 12. There was no significant difference between the groups in number of patients who maintained stable hemoglobin levels without epoetin alfa dose increases. Conclusion: This study demonstrates that a weekly subcutaneous administration of epoetin alfa is as effective and safe as injecting it two or three times a week administration in maintaining hemoglobin levels in stable hemodialysis patients.
