The aim of this study was performed to determine the inter-rater reliability of the Stroke Rehabilitation Assessment of Movement (STREAM) translated in Korean. Ths was a new clinical measurement tool for evaluating the recovery of voluntary movement and basic mobility following stroke. A direct-observation reliability study was conducted on 20 patients who had strokes and were in a rehabilitation setting. Subjects were assessed by two physical therapists. The reliability of the STREAM scores was demonstrated by weighted kappa statistics for inter-rater agreement on scores for individual items ranged from .83 to 1.0, intraclass correlation coefficients for total score was .99, and for subscale scores was ranged from .~ to .99. The internal consistency of the STREAM scores was demonstrated by Cronbach alphas of greater than .99 on the subscales and overall. These high levels of reliability support the use of the STREAM translated in Korean instrument for the measurement of motor recovery following stroke.

이 연구는 12주간의 저강도 유산소 운동 및 식이제한을 통해 Body weight, TLR5, Cytokine의 변화와 이들의 상관관계를 검증하기위한 목적으로 실시하였고, 이를 위해 4주령의 C57BL/6 수컷쥐(n=60)를 대상으로 고지방식이를 통해 비만유도 후 통제집단(CG), 저강도 유산소 운동집단(EG), 식이제한집단(DG), 식이제한+저강도 유산소 운동집단(DEG)으로 집단분류 하여 실험을 하였다. 실험종료 후 집단 간 비교를 위해 일원변량분석(one-way ANOVA)을 각 변인들간의 관련성 검증을 위해 Pearson의 상관분석(Pearson Correlation)을 실시하였으며, 결과를 종합하면 12주간의 저강도 유산소 운동과 식이제한은 체중 및 TLR5, Cytokine의 발현에도 영향을 미친다. 하지만 이 연구와 기존에 발표된 연구결과들은 주로 쥐를 대상으로 한 것이어서 인체에 대한 정확한 효과를 단정 지을 수 없다. 따라서 이 연구는 비만처치 방법에 대한 정보를 제시하였으며 이를 통해 더 나아가 인간을 대상으로 다양한 운동프로그램 개발 및 식이요법 개발에 기초자료가 될 수 있을 것으로 사료된다. This study was conducted to investigate the effects of low-intensity aerobic exercise and/or dietary restriction on body weight, TLR5 and Cytokines, and the relationships between them. Obesity was induced in C57BL/6 male mice (n=60) by high-fat diet, which were divided into four experimental groups, control group (CG), low-intensity aerobic exercise group (EG), dietary restriction (DG), and a combination of low-intensity aerobic exercise and dietary restriction group (DEG). And after a 12-week treatment of low-intensity aerobic exercise and/or dietary intake limit, the effects in four test groups were compared by one-way ANOVA, and Pearson Correlation was employed to verify the relationships among each factors, which led to the conclusions as follows. A 12-week treatment of concurrent low-intensity aerobic exercise and dietary intake limit was effective for weight-loss, exhibited a positive effect on TLR5, TNF-α and IL-6 than exercise alone or dietary restriction limit alone, and relationships of TNF-α, and body weight, and TRL5 were confirmed, too. Therefore, it is thought that this study can be the preliminary data to provide information to help develop various exercise programs for effective weight control based on new forms of factors causing obesity.

Based on the Korea National Health and Nutritional Examination Survey 6th 2015, this study was conducted to observe how drinking habits and physical activity levels affect cardiovascular disease risk factors and liver function factors of middle-aged men aged under 40-64 years. The Multivariate analysis of variance was used to compare the drinking habits and physical activity levels that affect ardiovascular disease risk factors and liver function. Multiple Logistic Regression was used to analyze the risk of physical activity level on drinking habits. As a result, there were no differences in the systolic blood preassure(SBP), diastolic blood pressure(DBP), fasting blood glucose(FBG), triglyceride(TG), HDL-C, LDL-C, total cholesterol(TC) and hs-CRP according to the physical activity levels. However, SBP. DBP. FBG, TG and TC was statistically higher in higher alcohol drink group(HADG) than lower alcohol drink group(LADG). LDL-C was statistically higher in LADG than HADG. Also, aspartate aminotransferase(AST) was higher in HADG than LADG, alanine aminotransferase(ALT) was significantly higher in moderate physical activity level(MAL) than low physical activity level(LAL) and high physical activity level(HAL). Among LADG and HADG, the ALT was higher in HADG. In addition, MAL had a lower odds ratio to be a HADG than LAL, and HAL had higher odds ratio to be a HADG than LAL. In conclusion, to improve cardiovascular risk factors and liver function of middle-aged men, drinking habits that lower Alcohol Use Disorders Identification Test(AUDIT) score are needed and moderate physical activity is the most effective.
