      • 확장된 네트웍 보안 모니터

        김윤기(Kim Youn-Ki),이계영(Lee Gae-Young),김규식(Kim Gyu-Sik) 한국정보과학회 1999 한국정보과학회 학술발표논문집 Vol.26 No.1A

        Intrusion detection과 network security는 컴퓨터 분야에서 점점 더 중요해지고 있다. 이로 인해 계속해서 침입탐지 시스템이 개발되고 있다. 네트웍 침입탐지 시스템에는 “중앙 집중식”과 “완전 분산형”이 제안되었다. “중앙 집중식”은 중안 제어 시스템에 과중한 부하를 유발시킬 수 있고 “완전 분산형”은 모든 호스트가 침입탐지 시스템을 수행시켜야하는 제한과 이로 인한 부하를 유발시킨다. 이런 단점을 해결하기 위한 방안으로써 각 랜마다 하나의 침입탐지 시스템을 수행시키는 방식의 분산 침입탐지 시스템 ENSM(Expanded Network Security Monitor)을 제안한다. 랜을 모니터하기 위해 설계된 NSM(Network Security Monitor)를 확장함으로써 제안하는 시스템을 설계한다.

        비디오게임을 활용한 가상현실 운동프로그램이 발달장애성인의 건강체력 및 신체활동수준에 미치는 영향

        강유석 ( Yoo Seok Kang ),이계영 ( Gae Young Lee ) 한국특수체육학회 2015 한국특수체육학회지 Vol.23 No.4

        본 연구는 성인기 발달장애인을 대상으로 비디오게임을 활용한 가상현실 운동프로그램(Wii fit plus)의 적용효과를 규명하고자 하였다. 구체적으로, Wii fit plus 프로그램(Wii집단)과 특수체육프로그램(APA집단), 그리고 특수체육프로그램과 Wii fit plus 프로그램을 혼합한 운동프로그램(APA+Wii집단)을 각각 적용하여 상대적인 효과성을 비교하고자 하였다. 이를 위해, C도에 거주하고 있는 40세 이상의 발달장애 성인을 연구 대상으로 선정하고, 3개의 실험집단과 1개의 통제집단으로 무작위(random sampling)로 할당하여 구성한 후 15주 동안 실험을 진행하였다. 이러한 과정을 통해 다음과 같은 연구 결과를 얻었다. 먼저, 신체조성 영역에서 근육량은 APA+Wii집단에서 가장 큰 변화를 보였으며, 체지방량은 APA집단에서 가장 큰 변화를 나타냈다. 건강체력의 경우, 평형성을 제외한 건강체력 요소들은 APA가 포함된 프로그램이 Wii 프로그램보다 효과성이 높은 것으로 나타났으며, 평형성은 Wii 프로그램이 상대적으로 효과성이 큰 것으로 나타났다. 마지막으로 보수와 칼로리 소비의 변화를 알아본 결과에서는 세 집단 모두 통제집단에 비해 향상된 결과를 나타냈으나, 전반적으로 특수체육프로그램의 기여도가 상대적으로 더 큰 것으로 나타났다. 이러한 결과는 발달장애 성인의 건강 및 활동성 증진을 위해 가상현실을 활용한 운동프로그램을 적용하고자 할 때 고려해야 할 시사점이 될 수 있다. The purpose of this study was to investigate the relative effects of physical activity program using video game based on virtual reality for adults with developmental disability. 28 subjects with developmental disability over 40 years were participated in the study. The subjects were divided into 3 experimental groups and 1 control group. Each group respectively had 7 subjects and took part in different protocols for 15 weeks. The subjects in Wii group participated in Wii fit plus(Nintendo Inc., Japan) programs based on video games, APA group performed field based adapted physical activity(APA) program, and Wii+APA group received program combined with Wii fit plus and APA 2 times a week. In order to compare the effects of different experimental protocols for each groups, body composition, health related physical fitness and physical activity level were measured before and after experiment. After the training, the muscle mass showed the biggest improvement in APA+Wii group and fat mass showed the biggest change in APA group. In health related physical fitness, it was revealed that programs include APA showed more effective than Wii in every areas except balance. In case of the steps and calorie consumption, 3 experimental groups showed relative improvement after training compare to control group, however APA was the biggest factor contribution to results. In conclusion, these results suggest that APA program based on the field may be effective approach to improve health-related physical fitness and physical activity of adults with developmental disability. Additionally, it is necessary to consider the understanding and adaptation to programs of participants and the composition of execution environment in order to utilize Wii programs.

        李啓暎,兪承熙 경희대학교 체육과학연구소 1990 體育學論文集 Vol.18 No.-

        The purpose of this study is to examine the specificity of maximum aerobic power and the anaerobic threshold (AT) in female football players. Raboratory assessements were made on eleven female football players. Each subject completed a continuous multi-stage treadmill running exercise procedure designed to achive maximum oxygen uptake. As the results of this study, Conclusions were obtained as follows; 1.The average means of maximal oxygen uptake (V07max) were 3.30±0.74ℓ/min, 58.18±9.30m1/kg/minin female football players. 2.Oxygen uptake at anaerobic threshold (AT-VO₂) was 1.7 lto.34ℓ/min. The AT was expressed by a percent of VO₂max. It was 52.65±6.84% in female football players.

Considering the meaning of the physical education in human relation philosophical system is inevitable for an academic research the futher development of philosophy of the physical education. 1. Sports and the physical activities comes out from natural requirement and man developed himself in the nature. 2. In the sport, power, physical fitness, physical excellency are all desiable, however it should be carried on in terms of 'idealism', which means the action is to be morally right. 3. In the Realism, sports focuses on the objective foacts rather than on subjective consept, it ideas to the slogan that "in the sound body, sound spirit." 4.

        李啓英,鄭義權 中央大學校 韓國敎育問題硏究所 1994 韓國敎育問題硏究所論文集 Vol.- No.9

        The academic study foundations examine into the philosophy of physical education. The philosophical approach of physical education seeks to comprehend the metaphysical, epistemic, and axiologic status of physical education and so reveal the fundamental character and nature of many philosopher's physical education thoughts. Therefore, a study of Locke's physical education thoughts, from a modern point of view, will be a notable crossroad in the development of philosophy of physical education. Locke put his aim of education on bringing up gentleman and thinks that the physical, moral, mental education and skill should be the elements of the education program to achieve this aim. Above all, he thinks the physical education the most important of all, based on the belief that is, ‘a sound mind in a sound body’. Locke main idea of physical education is health itself, which is built up by continual training. According to his opinion, the concept of the training is being habituated by practice through the experiences. Today his thought on preservation and improvement of health has been medically proved good for the health living. Locke regards swimming and dancing highly and suggested that the should be essential subject for the physical education. He also says that riding a horse and fencing are good exercise for health even though some defects in the skills are found in them. Locke regards recreation as a diversion of one's feeling. He also thinks it can not only relive both the mental and physical fatigue but also refresh one's mind. He advises to enjoy outdoor recreation for the physical exercise.

        This study was undertaken to examine the effect of Ginseng on physical fitness and physical work capacity. 30 soccer players at Kyung Hee high school were divided into two groups. One is control group with 15 players, and the other one is Ginseng group with 15 players. The members of Ginseng group were taken 8g of Ginseng powder per day totally. 4g in the morning and 4g in the evening before the each meal for the period of12 weeks. To evaluate the change of physical fitness, each member's weight, leg strength, back strength, sargeant jump, flexibility were measured and to estimate the transit of physical work capacity, Cycle Ergometer was operated to figure our such as heart rate, ventilation, respiratory rate, all out time, physical work capacity 170, by members of each group. Evaluation was completed by four steps. The post 1 was enforced before taking Ginseng. Post 2 was operated after taking Ginseng 4 weeks later. Post 3 and post 4 were executed by each 8 and 12 weeks after. The results are.as follows ; 1.
