  • Purpose: The purpose of this study was to examine the effect of a moderate-intensity, walking exercise program on the body composition, blood lipids and psychosocial outcomes in postmenopausal obese women. Methods: With a quasi-experimental pre- and post-test design, a total of 36 postmenopausal obese women was recruited in 2 metropolitan areas by convenience sampling. Sixteen women participated in 1 hour of moderate-intensity walking exercise 5 days per week for 3 months and 20 women did not. Cardiovascular risk factors include body composition and blood lipids. Body composition was measured as body mass index, % body fat, and waist/hip ratio; Blood lipids were measured with total cholesterol, triglyceride, HDL and LDL; psychosocial outcomes were evaluated by self-esteem and depression. Results: Over 3 months, the score of self-esteem increased and depression decreased in the exercise group relative to the control group. However, there were no significant differences in body composition and blood lipids. Conclusions: This study suggests that 3 months of moderate-intensity exercise training can improve psychosocial outcomes but further studies are needed to replicate walking exercise on physiologic variables among postmenopausal obese women. These findings are of public health relevance and add a new facet to the growing literature on the health benefits of moderate exercise.

  • Objectives: This study investigated the effect of physical activity of adult Korean males on the prevalence of diabetes mellitus. Methods: This cross-sectional study used the raw data from the 2017 Community Health Survey. The subjects of this study were 74,494 men aged 19-64 years old. The data was analyzed applying the complex sampling design and using SPSS 23.0 Program. Descriptive statistics, Rao-Scott Chi-square tests and multiple logistic regression analysis were all performed. Results: The prevalence of diabetes mellitus was 6.4%. The walking activity was 58.5% and the over moderate intensity physical activity was 27.5%. After adjusting for age, marital status, educational level, household monthly income, drinking and smoking status, and BMI, those subjects without moderate intensity physical activity had a 1.14 times higher prevalence of diabetes mellitus (95% CI = 1.05-1.24) than those men with moderate intensity physical activity. Conclusion: In order to decrease the prevalence of diabetes mellitus among adult men, regular physical activities over a moderate intensity level should be emphasized and encouraged in daily life.

  • Low power-low flow 유도결합 플라즈마 원자방출 분광법(ICP-AES)에서 분석적 특성에 대해 연구하였다. Low power ICP에서는 moderate power ICP보다 알짜세기는 감소하지만 바탕세기도 감소하여 알짜세기에 대한 바탕세기의 비는 오히려 증가하였다. Low power ICP에서도 작동조건에 따라 moderate power와 비슷한 검출한계를 얻을 수 있으며, 검량곡선도 $10^4{\sim}10^5$ 정도의 직선성을 가질 수 있었다. 알칼리 금속에 의한 이온화 방해영향은 시료운반기체의 사용량을 증가시킬수록 증가하지만, RF power의 변화에 대해서는 큰 차이가 없었다.

  • We investigated the effect of physical exercise on the intakes and plasma levels of vitamin C and E in young male adults. The study population were divided into two groups: small-amount exercisers($\leq$ 30min/day, n=29) and moderate-amount exercisers(> 30min/day, n=32) according to their physical exercise habits measured by a questionnaire. Dietary intakes of vitamin C and E of the subjects were estimated by the 24 hour recall method. Plasma lipid profiles, vitamin C, $\alpha$-tocopherol and ${\gamma}$-tocopherol levels were analyzed. No significant differences were observed in total cholesterol, TG, HDL-C and LDL-C of plasma between two groups. Plasma vitamin C and $\alpha$-tocopherol levels in moderate-amount exercisers were significantly higher than those in small-amount exercisers, although dietary intakes of vitamin C and vitamin E were not significantly different between two groups. However, plasma ${\gamma}$-tocopherol level of moderate-amount exercisers did not significantly differ from small-amount exercisers. There was a positive correlation between the amount of exercise and plasma $\alpha$-tocopherol level. These results suggest that moderate amount of exercise over 30 min per day would lead to a healthy life with an activated antioxidant defence system against oxidative stress.(Korean J Nutrition 34(3) : 306~312, 2001)

  • Purpose: The purpose of this study was to evaluate the effect on blood pressure (BP) and heart rate (HR) according to aerobic exercise characteristics in adults with hypertension using a systematic review and meta-analysis. Methods: The related researches were selected from PubMed, EMBASE, Cochrane library, CINAHL, PsycINFO, SPORTDiscus and 5 domestic databases up to September 4, 2019. To estimate the effect size, random effect models were used to derive weighted mean differences (WMD) and their 95% confidence intervals (CI) of aerobic exercise on BP and HR. Results: A total of 37 RCTs with 1,813 samples were included. Aerobic exercise was found to significantly reduce systolic BP (WMD, - 8.29 mmHg; 95% CI, - 10.12 to - 6.46), diastolic BP (WMD, - 5.19 mmHg; 95% CI, - 6.24 to - 4.14) and HR (WMD, - 4.22 beats/min; 95% CI, - 5.36 to -3.09). In detail, systolic BP and diastolic BP were significantly decreased in all groups of exercise types, frequency and duration. Systolic BP and diastolic BP were significantly decreased in the moderate and vigorous-intensity group. Exercise characteristics with the most dramatical change in systolic BP were water-based training, moderate-intensity, 3 times a week and 8 to 11 weeks of duration. In diastolic BP, the greatest effect size was over 24 weeks of exercise. Conclusion: Moderate aerobic exercise, especially water-based exercise can be an important part of lifestyle modification for hypertensive patients. Also, it can be recommended in a variety of clinical settings for lowering BP and HR. However, there is insufficient evidence that low-intensity exercise is effective in lowering BP.

  • 기존 연구에서는 주로 유통업자 브랜드와 제조업자 브랜드는 경쟁관계로 보았다. 하지만 본 연구에서는 유통업자 브랜드가 제조업자 브랜드를 소재 브랜드로 사용하면 유통업자 브랜드에 대한 소비자들의 저품질 인식을 변화시킬 수 있다는 측면을 이론적, 실증적으로 밝히고자 하였다. 연구결과 유통업자 브랜드가 제조업자 브랜드를 소재 브랜드로 사용하면 지각된 품질과 구매의도가 향상되는 것으로 나타났다. 그리고 제조업자 브랜드와 제품의 일치 정도가 중간일 때 소비자가 가장 긍정적인 반응을 보이는 것으로 나타났다. 이 관계에서 기능적 위험이 조절변수 역할을 하는 것으로 나타났는데 기능적 위험이 높을 때는 소비자들이 유통업자 브랜드와 제조업자 브랜드의 높은 일치성의 경우에 더 좋은 반응을 나타냈으며, 기능적 위험이 낮을 때는 중간정도 일치할 때 더 좋은 반응을 나타냈다.
