The purpose of this study was to investigate the effects of gross motor training program on gross motor developments in children with severe mental retardation. For this study gross motor training program was offered to 26 subject children with mental retardation for 40 minutes 3 time a week for 16 weeks. Gross motor training was applied by Sieglinde Martin. To study the effects of gross motor training, gross motor was measured by Gross motor fuction measurement scale before and after the training. The results of the effects of gross motor training on gross motor development were summarized as follows: There were some significant development in the 7 areas of the gross motor such as lying, rolling, sitting, crawling, kneeling and standing, after 16 weeks training.

Effect of the supplementation of fructose and taurine on energy metabolism during exercise

장명재,최성근,김영민 한국운동영양학회 2012 Physical Activity and Nutrition (Phys Act Nutr) Vol.16 No.2

The purpose of this thesis is to investigate whether taurine supplementation in combination with fructose improves both energy metabolism and exercise capacity. Eight collegiate female subjects were recruited for the study. Each subject went through threecross-over designs: control(fluid), fructose, and taurine plus fructose supplementation trials. Subjects received taurine supplementation 100 mg/kg a day for two weeks. After the supplementation, all subjects take 10% fructose at 15 min prior to exercise, immediately before exercise, and every 15 min during exercise. Subjects received 150 ml fluid as placebo during the same procedure. The subjects performed submaximal exercise at the exercise intensity of 60% for 45 min and then 80% of maximal oxygen uptake (VO2max)until exhaustion time. A 10ml blood sample was taken for measuring the level of glucose, ammonia, lactate, free fatty acids, and insulin every 15 min during exercise at 60% of VO2max. The blood glucose levels was significantly higher at 45 min and 50 min exercise after supplementation of fructose, and immediately before exercise and 50 min exercise after taurine plus fructose compared to the placebo trial. However, the values tended to be lower in taurine plus fructose supplementation compared to the fructose trial. The levels of both lactate and ammonia were significantly lower compared to the placebo, while the exhaustion time was significantly increased. The level of free-fatty acids was significantly lower at 30, 45, and 50 min after fructoseand fructose plus taurine supplementation compared to the placebo trial. The level of glucagon was significantly lower at 15, 30, 45, and 50 min after fructose and fructose plus taurine supplementation compared to the placebo trial. There was no differences in insulin concentration among three treatments. This thesis concludes that combined taurine and fructose supplementation prior to exercise may improve exercise tolerance time and energy metabolism, lowering the muscle fatigue factors such as lactate and ammonia.

소형 무인 항공기 탐지를 위한 인공 신경망 기반 FMCW 레이다 시스템

Drone detection in FMCW radar system needs complex techniques because a drone beat frequency is highly dynamic and unpredictable. Therefore, the current static signal processing algorithms cannot show appropriate detection accuracy. With dynamic signal fluctuation and environmental clutters, it can fail to detect a drone or make false detection. It affects to the radar system integrity and safety. Constant false alarm rate (CFAR), one of famous static signal process algorithm is effective for static environment. But for drone detection, it shows low detection accuracy. In this paper, we suggest neural network based FMCW radar system for detecting a drone. We use recurrent neural network (RNN) because it is the effective neural network for signal processing. In our FMCW radar system, one transmitter emits FMCW signal and four-way fixed receivers detect reflected drone beat frequency. The coordinate of the drone can be calculated with four receivers information by triangulation. Therefore, RNN only learns and inferences reflected drone beat frequency. It helps higher learning and detection accuracy. With several drone flight experiments, RNN shows false detection rate and detection accuracy as 21.1% and 96.4%, respectively.

탈상업화를 지향하는 효과적인 예술경영전략 - 버닝맨 축제의 경영철학을 중심으로 -

장명재 대한경영정보학회 2021 경영과 정보연구 Vol.40 No.3

오늘날 예술은 사람들의 삶과 밀접하게 연결되어 있다. 그리고 예술을 향한 대중의 관심도가 높아질수록 이를 상업적으로 이용하는 사람과 단체의 수도 증가하고 있다. 그 이유는 예술에 대한 대중적 관심은 자유 시장경제 체제 속 경제적 이윤 창출로 연결되기 때문이다. 이러한 환경에서 예술은 갈수록 더 상업화되어가 는 경향을 보인다. 이처럼 예술이 상업화되어가는 과정에서 적지 않은 부작용이 발생하고 있다. 대표적으로 는 예술 속 상업적 가치가 예술적 가치보다 더 중요한 성공의 기준이 되어가는 경향을 볼 수 있다. 본 연구 는 성공적인 예술의 탈상업화 방안을 모색해보았다. 그리고 탈상업화된 예술의 대중적인 성공 가능성을 확 인했다. 이를 위해 미국의 버닝맨 축제를 연구했다. 버닝맨 축제는 탈상업화를 지향하는 축제다. 특히 1986 년부터 현재까지 진행되고 있고 성공적인 축제의 대표 사례 중 하나다. 연구 결과 예술의 탈상업화도 대중 적인 성공이 가능한 것으로 나타났다. 하지만 이 경영철학이 해당 예술 관련 행사의 전반적인 운영과정에 영향을 미쳐야 하는 것으로 나타났다. 또한, 지속할 수 있고 대중적으로 성공하기 위해서는 이러한 경영철학 과 사람들의 욕구가 연결되어야 한다는 점도 밝혔다. 결론 부분에서는 예술의 탈상업화의 대중적 성공을 위 한 방안과 연구 결과가 예술경영 분야에 관심을 두고 있는 개인과 단체들에 이바지할 수 있는 부분을 제시 하였다. Today, art is closely associated with people's lives. While people's interest in art increased, the number of people and organizations that use this commercially has also increased because popular interest in art leads to profit in the free market economy. In this environment, art tends to become more commercialized, followed by a number of side effects. Typically, it can be seen that commercial value in art tends to become a more important criterion for success than artistic value. This study explored the possibilities for the successful decommercialization of art and confirmed the potential for popular success of decommercialized art. For this, the Burning Man Festival of America was examined. The Burning Man Festival is aimed at decommercialization. In Particular, it has been running from 1986 to the Present and is one of the representative examples of successful festivals. As a result, the decommercialization of art could turn into a popular success. However, this management philosophy had to influence the overall operation of the art-related events for the decommercialized art to be successful. It was also pointed out that this management philosophy and the needs of people must be connected to gain sustainability and popular success. In the conclusion, measures for the public success of the decommercialization of art and the research results that can contribute to individuals and organizations interested in the field of art management were proposed.
