Lately, every year over 10,000 casesof drowning accident are occurred and has also increased casualties accordingly. These damages have caused a great loss personally and nationally. Specially, accidents near natural waterside such as sea, river, lake and etc. were more than 80% in total drowning accidents. In South Korea, traditional swimming education is for the record, in other words swimming race was the major purpose of education, and the recognition of the common people who try to learn swimming are for competition or for the record, whereas Europe and Japan changed the purpose of swimming education long time ago for an example, teach swimming as a part of water safety education to prepare for the drowning accidents by training swim with wearing normal clothes. These point of view and approach has great implications for our country swimming education. In the current situation of our country which there is no recognition of the swimming with wearing normal clothes, this study raises the need for education about the swimming with wearing normal clothes. As a result, the swimming with wearing normal clothes has differences between the common swim and each stroke in swimming efficiency which is swim speed. The breaststroke was suggested as the finest swim stroke for the swimming with wearing normal clothes, but when swim for short distance with light dress in summer season, freestyle stroke had also been reported to be effective(Choi, 2001). With those reports, pre-training education about coping methods in a variety of situations in advance has been emphasized that is very important. In particular, studies on the swimming with wearing normal clomal clothes will be used as a basis for forming water safety education, and activating water safety education can be expected the reduction of drowning accidents.

최승욱(Choi Seung-Wook) 한국체육과학회 2004 한국체육과학회지 Vol.13 No.1

For a comparative study between swimming in swimwear and swimming in clothes, oxygen uptake (?o₂) and ratings of perceived exertion (RPE) were measured. The subjects were six male members of a university swimming team. Three swimming strokes - the breaststroke, the front crawl stroke and the elementary backstroke - were applied. With regards to swimming in clothes, swimmers wore T-shirts, sportswear(shirt and pants) over swimwear and running shoes. In both cases of swimming in swimwear and swimming in clothes, the Vo₂ was increased exponentially with the rise of swimming speed. The ?o₂ of the subjects during the clothed tests did not exceed 1.4 times of that in case of swimming in swimwear at swimming speeds below 0.3㎧. As the swimming speeds increased, the ?o₂ difference in both cases increased. Consequently, the ?o₂ in the clothed tests was equal to 1.5-1.6 times and 1.5-1.8 times of that in the swimwear tests at speeds of 0.5㎧ and 0.7㎧, respectively. AT speeds below 0.6㎧ in swimming in clothes, the breaststroke showed lower Vo₂ than the front crawl stroke, and the elementary backstroke showed higher ?o₂ than the other two swimming strokes. RPE increased linearly with %?o₂max. In addition, any RPE difference among the three swimming strokes was not shown in the swimming in swimwear tests. However, at an exercise intensity above 60%?o₂max, clothed swimmers showed slightly higher RPE in the front crawl stroke compared to the RPE in the two other swimming strokes.

The purpose of this study was to investigate the effect of lower extremity muscular function on aerobic capacity of adult women. The subjects were 10 adult women whose muscle function tests were carried out at knee joint, hip joint, and ankle joint via weight, height, and body composition measurement and isokinetic test. In addition, aerobic capacity was measured by a gradual speed that increased the load every minute using a treadmill. Correlation analysis was performed to investigate the effects of lower extremity muscle function on aerobic capacity, and regression analysis was used to analyze muscle function with the closest relationship to aerobic capacity among the lower extremity muscles. As a result, there was a significant positive correlation between 60°/sec flexion and VO2max at(r=.588, p<.05). 45°/sec Flexion (r=.807, p<.01), 300°/sec Flexion(r=.703, p<.01), and Extension(r=.595, p<.05) of hip joint showed significant correlation to VO2max. In addition, it is the result of analyzing the effect of ankle joint muscle function on aerobic capacity. 0°/sec Plantarflexion (r=.704, p<.01) and 60°/sec Plantarflexion(r=.575, p<.05) indicated significant positive correlation to VO2max. Finally, among the many muscle functions of the knee, hip and ankle joints, 45°/sec flexion of the hip joints showed the greatest effect on VO2max(p<.01), and 65% of VO2max could be explained as a predictable factor. In conclusion, it was clearly apparent that flexion muscle function of the hip joint was a significant factor that could predict 65% of VO2max. Thus, the improvement of the flexion muscle function of the hip joints is essential to improving the aerobic capacity of adult women, and it is the part that must be involved in setting up an exercise program to improve aerobic capacity.

The previous studies shows that in case of flatland walking, a free step requires minimum energy, while intentional control of steps increases energy consumption. However, the purpose of this study is to prove the fact that the intentional control of steps increases energy consumption not only in flatland waking but also in incline walking. In case of flatland walking, it is reported that long steps reduce the rate of waking still larger than short steps and also increases energy consumption. However, the result of this study for incline walking indicated: In a downhill, long steps influenced the rate of walking much larger than short steps. In a uphill, short steps influenced the rate of walking as same as or rather larger than long steps. This means that the intentional reduction of steps in a uphill is related to the increase of energy consumption much more than that in a downhill. And this study also estimated economical steps to minimize energy consumption by examining the relation between oxygen intake and steps. The result shows that the economical step tends to increase in proportion to the tilt. Moreover the estimated economical step implies that the pace tends to reduce both in uphill walking and in downhill walking, and the control of steps and paces in incline walking is closely related to walking with the good energy efficiency.

This study was to measure and compare the muscle strength of the lower limbs of sports majors and non-sports majors and to examine its relation with balancing ability. First, After measuring isokinetic muscle strength of the two groups at an angular velocity of 60°/sec in order to identify differences by group, no significant differences were found in all items. When measuring them at an angular velocity of 300°/sec, a significant difference was observed in the right extensor(p<.05). Second, When measuring the balancing ability of the two groups with their eyes blindfolded, there were no significant differences in the right-side anteroposterior stability and the right- and left-sided mediolateral stability, while a significant difference was found in the left-side anteroposterior stability(p<.01). Third, After examining the correlation between isokinetic muscle strength and balancing ability by targeting the entire study participants, there were no correlation between them in most of the items. However, the study found a high level of correlation at -.681 between the left-side anteroposterior stability and the right-side tensor(p<.05). Based on the above results, one needs to move the body quickly to strike the balance in order prevent fall when the balance is disrupted, and given this, it is necessary to boost the strength of muscles required for nimble body movement than improving the muscle strength of the lower limbs.

최근 들어 사회구조가 다원화, 다양화 형태로 변하면서 소비자의 감성을 중시하고 자기만족을지향하는 개성중심의 스타일로 전환되고 있으며 이에 따라 소비자의 다양한 개성이나 취미를 반영한 디자인의 주얼리들이 잇따라 출현하고 있다. 이러한 현상의 중심에는 현재 사회 문화현상 중의 하나인 퓨전현상이 자리 잡고 있다. 퓨전은사회가 흘러가며 공유하는 유행이나 시대분위기에 따라 변하면서 뒤섞이는 나름대로의 시대성을띈 절충적인 문화현상이다. 퓨전현상은 현대사회에 갑자기 나타난 것은 아니며 인류역사 이래과거부터 끊임없이 시대 상황에 따라 조금씩 변하면서 다르게 나타났다고 볼 수 있다.본 연구에서는 과거와는 또 다른 사회적 특성을 배경으로 대두되고 있는 퓨전현상의 개념과 형성배경, 특성 등을 알아보고, 퓨전현상이 사회에 미친 영향을 디자인, 예술, 대중문화별로 조사하였으며, 현대 주얼리 디자인의 퓨전적 요소들을 4가지로 구분하여 분석하였다.이러한 사회문화 전반에 나타난 퓨전현상들과 현대 주얼리 디자인과의 상호 관계의 연구를 통해, 현대 주얼리의 다양하고 새로운 디자인적 요소의 창출과 미래트렌드를 예측할 수 있는 통찰력을 키울 수 있으며, 동시에 퓨전문화를 이해하고 이질적인 문화를 조화롭게 공존시켜나가는보편문화의 추구와 국제적인 안목을 기를 수 있는 토대를 구축하고자 하였다. As the society becomes pluralistic and diverse, styles have changed personality oriented thriving for self-satisfaction, and as this happens, jewelries with unique designs have appeared. In the center of this is what is called the Fusion Phenomena which is one of the social cultural phenomenons. Fusion is a compromising cultural effect that takes place with the flowing of trend and era that eventually mixes. However, such fusion phenomenon is not something that appeared all of a sudden, but has changed and reflected the era since the beginning of history. This study identifies the concept of fusion phenomena and its background which is quite different from what it used to be in the past, analyzed the effect of fusion phenomena on design, art and social culture, and classified modern jewelry design into four fusion factors. Through the study of correlation such fusion phenomena has with modern jewelry design, insights of future trend were tried to be built as well as creating new design factors for modern jewelries, and at the same time, tried to establish a base for understanding fusion culture, thriving for a general culture that can co-exist with heterogeneous culture and a framework to grow international views.
