Korea has already become the fastest aging society in the world. The rapidly aging population will undoubtedly cause various health problems not experienced so far. This study classified two groups with age over 65 healthy elderly women(30 patients). One group exercised regularly over 3 years, 3 times a week (70.27±3.9) while the other group did not exercise regularly (71.07±3.8). The study aimed to discover the metabolic syndrome risk factors and impacts on arterial stiffness. This data were analyzed by independent t-test and multiple regression. Results were as follows. 1. FM [4(28)=2.217, p=.035)] and %BF [t(28)=2.630, p=.014)] of the non-exercise group were significantly higher than those of the regular exercise group. 2. Metabolic syndrome risk factors SBP [t(28)=4.224, p=.001], WC [t(28)=2.768, p=.010)], HDL-C [t(28)=2.923, p=.007)] and Glucose [t(28)=3.441, p=.002) of the regular exercise group were significantly higher than those of the non-exercise group. 3. RbaPWV [t(28)=16.060, p=.001] and LbaPWV [t(28)=14.223, p=.001] of the regular exercise group were significantly lower than those of the non-exercise group. The results indicate that regular exercise provides a positive impact in the metabolic syndrome risk factors and artery stiffness of elderly women. It also prevents arteriosclerotic vascular disease such as the cardiovascular and cerebrovascular disease, helping to maintain health and improve quality of life. This suggests the importance of systematic exercise habits.

쇼윈도우 디스플레이는 고객과 최 접점에서 상품에 정보가치를 부가하고 브랜드의 메시지를 전달하여 이미지를 형성하게 하므로 판매활동에 있어서 중요한 요소이며 브랜드들의 치열한 경쟁 속에서 고객을 매장 안으로 유입하고 타 브랜드와의 차별화 전략으로서 쇼윈도우 디스플레이의 전략적 운용의 필요성이 강조되고 있다. 본 연구의 목적은 소비자의 구매의도 및 쇼윈도우 디스플레이 연출 유형에 대한 반응 분석을 통해 브랜드에서 쇼윈도우 디스플레이를 운용하는데 도움이 되는 가이드라인을 제시하고자 한다. 연구방법으로 본 연구는 설문지법을 활용하였으며 설문조사는 서울 및 수도권에 거주하는 20대 여자대학생을 200명을 대상으로 쇼윈도우 디스플레이에 대한 소비자의 평가 반응을 분석하고 구매 의도와의 상관관계를 파악하고자 하였다. 연구결과 계절감 코디네이션을 중심으로 연출한 쇼윈도우 디스플레이 경우에는 다른 브랜드와의 차별화나 그 브랜드의 시즌 주력 컨셉을 소비자에게 전달하는데 다소 미흡하며 구매 의도 빈도가 컨셉 스토리 테마를 중심으로 연출한 쇼윈도우와 비교할 때 낮은 것으로 나타났다. 컨셉 스토리 테마를 중심으로 쇼윈도우 디스플레이를 연출한 경우는 시즌 주력상품에 대한 인식 및 매장유입의 긍정적인 태도를 형성하는 것으로 나타나 쇼윈도우 디스플레이 연출에 따라 동일한 브랜드에 대한 느낌이나 반응 구매의도가 다르게 나타나는 것을 알 수 있었으며 쇼윈도우 디스플레이가 구매로 이어지기 위해서는 연구결과를 바탕으로 명확한 컨셉 스토리와 시즌 주력 상품을 미리 계획하고 연간디스플레이를 반영한 쇼윈도우 디스플레이의 운용 전략이 요구된다. Show window displays are one of the critical elements in sales activities granting information value to products conveying brand messages and creating images at the first contact points with customers. Thus there is increasing emphasis on the strategic operation of show window displays as a strategy to attract consumers into the store and differentiate a brand with its rivals in fierce brand name competitions. The purposes of this study were to analyze consumers' purchase intentions and reactions to show window displays and offer some helpful guidelines to brands in the operation of show window displays. A questionnaire was distributed to 200 female college students in their twenties living in Seoul and its metropolitan area in order to analyze their assessments and reactions to show window displays and examine any correlations with purchase intention. As a result when a show window display was directed around a sense of season or coordination it recorded a rather low level of performance in differentiating a brand from its competitors and conveying the brand's major concept for the season to consumers and a lower frequency of purchase intention than show window displays around a concept or story theme. When a show window display was directed around a concept or story theme it contributed to a positive attitude toward the main product of the season and store attraction. Those findings show that different show window display directions lead to different feelings reactions and purchase intentions for the same brand. Thus there is a need to set a clear concept and story plan a major product for the season in advance and implement a show window display operational strategy reflecting the annual display plan based on the findings in order to help show window displays bring in purchases.

The purpose of this study was to examine relationship between atherosclerosis and adiponectin according to metabolic syndrome in middle aged women. The subjects were 40 middle aged women. They were divided into two groups: metabolic syndrome(n=20) and normal(n=20). The analysis of data revealed the following findings. Atherosclerosis and adiponectin showed significant according to metabolic syndrome. Metabolic syndrome group had significantly faster b-aPWV in comparison to normal group. Adiponectin were significantly lower metabolic syndrome group than normal group. Right ABI showed significant negative correlation with ABI SBP, WC, HDL-C in normal group. Right b-aPWV showed significant correlation with HDL-C and left b-aPWV showed significant negative correlation with TG in normal group. Left b-aPWV showed significant correlation with HDL-C and showed significant negative correlation with WC in metabolic syndrome group. Adiponectin showed significant negative correlation with DBP and TG in metabolic syndrome group. In conclusion, middle aged women with metabolic syndrome had higher risk factors of atherosclerosis and adiponectin. We found a significant relationship between decreased atherosclerosis and adiponectin. There are needs for prospective study about the possible development of metabolic syndrome for prevention of atherosclerosis and adiponectin. Therefore, we should strive to develop the exercise program for prevention of cardiovascular disease would improve quality of life in middle aged women.

The purpose of this study was the effects of 20 minutes of exercise on the circadian rhythm of energy expenditure, glucose and lactate in female university students. As circadian rhythm exists in human body, effect of exercise may vary in accordance with time zone that exercise is executed even if the exercise is done with same strength, it is necessary to examine the result based on morning exercise(09:00),afternoon exercise(14:00), and evening exercise(20:00). In evaluating circulatory faculty, energy expenditure after 60%VO2max treadmill exercise which is based on circadian rhythm, glucose and lactate were measured in different time of a day after choosing female university students. Conclusion which may be drawn from this study is as follows: It is considered that female university students before and after exercise for 20 minutes have influence on energy expenditure, glucose and lactate in connection with circadian rhythm. Before and after exercise, glucose was significantly increased in the morning. Glucose was significantly decreased m the Afternoon. Before and after exercise, the change of lactate showed a significant increase at all times(morning, afternoon and evening). The increase in the lactate was most prominent in the morning. Morning, afternoon energy expenditure changes showed that the deterioration in the 20 minute exercise. These findings suggest exercise beneficial effects on the circadian rhythm especially in the evening.

The purpose of this study was to compare young children`s daily activities in the preschools of two different child-care approaches, i.e., project and traditional approaches. From two preschools, 20 children (M=71.3 months) were observed for 3 consecutive hours. The observers followed the target child, gathering data during 30-second "windows". The window was open every 2 and half minutes. To test the differences between two preschools, phi coefficient tests were used. Results showed that children of traditional approach were more exposed to and engaged in academic activities than those of project approach. In specific, children of traditional approach were more involved in academic and skill/nature lessons. A reverse tendency, however, was found in play activities. Children of project approach were more exposed to and engaged in play activities, especially in play with academic objects. And they were more exposed to conversation with their teacher than their counterparts. Children of project approach also showed more initiatives in their play activities.
