간호윤리 교육에서 토론학습이 간호대학생의 비판적 사고성향, 윤리적 가치관, 도덕 판단력에 미치는 효과
이선희,김순희 한국자료분석학회 2017 Journal of the Korean Data Analysis Society Vol.19 No.4
The purpose of this study is to compare the effects of a debate with those of lecture education on critical thinking disposition, ethical values and moral judgment. The experiment was performed for 9 weeks. Participants were 75 undergraduate nursing students in D city. 39 students was assigned to an experimental group and 36 students was a control group. The result of them showed that the experimental group reported significantly higher scores of the ethical values (t=-6.07, p<.001) and critical thinking disposition (t=3.47, p=.001) than the control group. There was a significant difference in ethical value and critical thinking disposition in mean difference comparison of post test. In conclusion, this study showed that providing a debate course to nursing ethics education could be more effective than lecture. Therefore, this study suggest to apply various teaching strategies and develop educational programs to improve nursing ethical values and critical thinking disposition. 본 연구의 목적은 간호윤리 교육에서 CEDA 아카데미 토론학습과 전통적 강의학습이 비판적 사고성향, 윤리적 가치관 및 도덕 판단력에 미치는 효과를 비교하기 위함이다. 본 연구는 간호윤리교육이 이루어지는 간호대학생 75명을 대상으로 하였고, 실험군(39명)과 대조군(35명)으로 구성한 비동등성 사전 사후 유사실험연구이다. 연구결과 CEDA 아카데미 토론학습을 적용한 실험군이 전통식 강의학습을 적용한 대조군보다 사후 윤리적 가치관(t=-6.07, p<.001)과 비판적 사고성향(t=3.47, p=.001) 점수가 유의하게 높았다. 또한 사후 실험군과 대조군의 평균차이 비교에서도 윤리적 가치관과 비판적 사교성향에서 유의한 차이가 있었다. 그러나 두 집단 간에 도덕적 판단력은 유의한 차이가 발견되지 않았다. 따라서 CEDA 아카데미 토론학습이 간호대학생의 윤리적 가치관과 비판적 사고성향을 향상시키는 것을 알 수 있었고, 향후 간호윤리 교육에 CEDA 아카데미 토론과 같은 다양한 교수 학습전략이나 교육 프로그램을 개발, 적용할 필요가 있다.

This study was performed to investigate the anti-hyperglycemia effects of the Triticum aestivum wheat sprout (TAWS) water extracts in the diabetic mice. Diabetic experimental model was established by intraperitoneal injection of streptozotocin into male Balb/c mice. Mice were divided into five groups: normal (CON), diabetic control (DM), and three experimental groups (DM-100, diabetes with TAWS extracts 100mg/kg; DM-50, diabetes with TAWS extracts 50 mg/kg; DM-25, diabetes with TAWS extracts 25 mg/kg). TAWS extracts were administered orally in diabetic mice. Body weight, food intake, and blood glucose levels were recorded for 12 days and blood insulin levels were measured at the day 12. Oral administration of TAWS extracts reduced slightly food intake and induced a little body weight gain in DM-100 groups. The blood level of glucose was decreased in the dose-dependent manner; 55% in the DM-100 group and 39.7% in the DM-50 group. The blood level of insulin also was improved 10 folds in the DM-100 group and 3.6 folds in the DM-50 group compared to the DM group. The contents of total phenolic compounds and total flavonoids in 1 g dry mass of TAWS extracts were 6.6 mg of tannic acid equivalents and 1.0 mg of 8-hydroquinolline equivalents, respectively. In addition, the antioxidant and DPPH radical scavenging activity of TAWS extracts were 1.2 mM and 1.8 mM ascorbic acid equivalents, respectively. These results suggest that TAWS water extracts could contribute to attenuate clinical symptoms of diabetes mellitus.
제2형 당뇨모델 db/db 마우스에서 밀순 물추출물의 항당뇨 효과

We evaluated the anti-diabetic effects of Triticum aestivum sprout water extract (TA) in diabetes mellitus type 2. For the experiments, the diabetic animal model db/db mice were divided to 3 groups: diabetic control (db/db) and two experimental groups orally treated with 25 and 100 mg/kg single dose of TA (TA-25 and TA-100, respectively). The lean mice were used as the non-diabetic normal control. All mice have free access to water and AIN-93 diet. TA was administrated to diabetic mice for 5 weeks and the diabetic clinical markers, including blood glucose level, body weight, food intake and insulin level,were measured at a time. After administration for 5 weeks, the blood glucose level was decreased 1.10 and 1.98 folds in TA-25 and TA-100 groups, respectively, compared with db/db group. The body weight and diet consumption were significantly reduced by TA treatment in dose-dependent manner. The treatments of TA-100 also significantly decreased remarkedly liver weight and slightly serum insulin levels when compared with them of the diabetic control group. However the immunohistochemical staining for insulin clearly showed high expression of insulin in the pancreatic islet cells derived from all db/db mice, even if TA was administrated. Moreover, TA-100 treatment significantly improved impaired glucose tolerance in diabetic db/db mice. The results suggest that TA has anti-hyperglycemic effect attenuating blood glucose in the animal model of type 2 diabetes and might be useful as a functional diet for human diabetic diseases.
