In the near future, we can access the information whenever we want, wherever we use because almost devices in ubiquitous environment are connected by either wired or wirelss networks. Especially, u-Learning which emphasizes on pedagogical property is enable to improve learning abilities. As researches of the previous u-Learning, there have been learning by mobile devices such as PDAs as well as the smart classroom which makes the remote students participate in the existing class. However, these researches have not satisfied pedagogical, cooperative and ubiquitous properties yet. Thus we suggest the framework for both local and mobile classroom, which can make the properties easy to satisfy. 향후 도래하는 유비쿼터스 환경에서는 모든 전자기기가 유/무선 통신망으로 연결되어 사용자는 언제 어디서나 원하는 정보에 접근할 수 있다. 특히, u-러닝(Ubiquitous-Learning)은 교육학적인 측면 뿐 아니라 어디서나 접근할 수 있다는 유비쿼터스적인 측면을 통해 학습의 효과를 보다 향상시킬 수 있다. 현재까지 추진된 u-러닝의 연구사례로, 주어진 학습 컨텐츠를 PDA를 이용하여 야외에서 학습할 수 있도록 하며, 원격지 모바일 환경의 학생들을 교실 수업에 참여시키는 스마트교실 등이 있다. 그러나 기존의 연구들에서는 학습자의 상호작용이나 협동학습 등의 교육학적인 속성과 유비쿼터스의 환경적 속성을 만족시키지 못함에 따라 본 연구에서는 어디서나 교실 환경에 참여하는 유비쿼터스 환경에 적합하면서도 교육학적인 면을 만족시키는 모바일 교실 프레임워크를 제안하고자 한다.

This study was conducted on 10 male ssireum players, who regularly exercise, to verify the effect of Kinesio taping on athletic performance and fatigue recovery. The analysis results for the change of anaerobic athletic capabilities (mean power, peak power, and fatigue index) and concentrations of muscle fatigues (lactic acid, ammonia, and inorganic phosphate) measured through Wingate Test depending on whether the Kinesio taping was used are as follows. SPSS 18.0 Window statistical program was used for this analysis. First, mean power, peak power and fatigue index, which are the anaerobic athletic capabilities, showed no differences between the groups, but were significantly decreased after 2 exercises according to the exercising times. There was no interaction between the exercising time and the group. Second, the concentration of lactic acid showed significantly lower in the taping group, and was high before and after one exercise, and before and after two exercises according to the time. There was no interaction between the time and the group, but significantly less lactic acid was verified to be created in the taping group. Third, the concentration of ammonia showed lower at the taping group than at the non-taping group, and was high before and after one exercise, and before and after two exercises according to the time. But there was no interaction between the time and the group. Fourth, inorganic phosphate concentration showed no difference between the groups, but was high before and after one exercise, and before and after two exercises. But there was no interaction between the time and the group. In conclusion, the Kinesio taping helped reduce muscle fatigues by improving blood supply to muscles, but have no effect on anaerobic athletic capabilities. Concentrations of lactic acid and ammonia, which are muscle fatigue substances, showed lower in the taping group than in the non-taping group, but muscle fatigues were not statistically significant in the test. In the future, continuous studies will be required to verify the effect of the Kinesio taping on the repeated anaerobic exercises or the exercises with sophisticated technical factors.

With disabled elderly with brain lesion as subjects, changes in body composition, bone density, muscular strength, and flexibility after elastic band exercise of 12 weeks were analyzed as an effort to use elastic band as a method of stamina increase and rehabilitation for disabled elderly with brain lesion. 12 disabled elderly with brain lesion were performed of paired t-test on body composition, bone density, muscular strength, and flexibility before and after elastic band exercises. As a result, after elastic band exercise of 12 weeks, abnominal obesity significantly decreased(p<.05), whereas muscular strength increased in both left and right(p<.01). However, flexibility, bone density, body fat, etc. did not show significant difference. To be considered as an effective exercise program for improvement of body composition and bone density, a further study on exercise intensity should be performed.

퍼베이시브 컴퓨팅 환경은 미국 표준화 기구인 NIST와 IBM이 함께 추진하고 있는 개념으로써 유비쿼터스와 유사한 의미이나, 개념적으로만 쓰이는 유비쿼터스와는 대조적으로 IBM에서 추진하는 하나의 사업적 상품명으로 취급되고 있다. 이러한 환경에 기초하여 침입탐지용 모바일 에이전트에 대한 연구가 함께 진행 중이다. 이 논문에서는 침입탐지를 위한 모바일 에이전트에 대한 연구를 다룬 후, 침입 탐지에 있어서 다중 모바일 에이전트를 기반으로 이동중의 모바일 에이전트를 이용한 침입 탐지 시나리오를 제안한다. 이를 통해 침입 탐지에 있어서 무결성 이동성의 과정에서 발생하는 침입 탐지 문제를 해결할 수 있었다. Pervasive computing environment is similar to the meaning of ubiquitous computing, however it is a kind of the commercial product, which is made from the collaboration between NIST and IBM. On the basis of this environment, the research of mobile agents for intrusion detection is going on in progress. In this paper, we study the research about mobile agents for the intrusion detection and then suggest scenarios using moving mobile agents based on the multiple mobile agents in the intrusion detection. Subsequently, we could figure out the problems which occurred through progress of integrity movement as a matter of the intrusion detection.

There are numerous benefits from using simulation tools such as a numerical model for engineering analysis. These tools can often provide information that can only be obtained through expensive experiments or may not be available any other way. Accurate prediction how the fly ash behaves in the superheater requires detailed knowledge of the aerodynamic properties of the fluidized particle and turbulence modeling techniques. Several solutions were evaluated for this boiler including current design and numerically optimized design that involves baffles to the particles. The aerodynamic solution was selected and baffles were designed for installation. Using numerical models also permitted an optimization of the baffle position to achieve the low velocity near the superheater tubes.

본 연구는 장기간 유도훈련이 골밀도와 심혈관질환 예측인자들에 미치는 영향을 알아보기 위해 유도선수 13명, 운동을 실시하지 않는 대학생 13명, 총 26명을 대상으로 골밀도, 신체조성, 혈중지질을 측정하였다. 이결과를 SPSS/PC 20.0을 사용하여 평균 비교 분석과 상관관계 분석 및 회귀분석 그리고 관련성 분석을 실시한 결과 유도선수와 비운동선수들의 평균차이분석에서 골밀도는 대퇴골(p<.01), 척추(p<.001), 전신(p<.001) 골밀도에서 유도선수가 더 높은 골밀도를 나타내었다. 심혈관질환 예측 인자는 Muscle Mass(p<.05)에서 유도선수가, Triglyceride(p<.01)에서는 비운동선수가 높게 나타났다. 골밀도와 심혈관질환 예측 인자 상관관계에서 유도선수와 비운동선수 모두 골밀도와 Muscle Mass(p<.01) 비교적 높은 상관관계가 나타났다. 다중회기 분석 결과 골밀도의 기여도는 Muscle Mass(p<.01) 가장 높았다. 골밀도가 낮은 그룹과 높은 그룹에 대한 관련성 분석에서는 유도선수가 높은 골밀도 그룹에 많이 분포했다. Muscle Mass가 높을수록 높은 골밀도에 많이 분포했으며, Triglyceride가 낮은 집단이 높은 골밀도에 많이 분포했다. In this study, bone mineral densities, body compositions, and serum lipids are measured for a total of 26 subjects, 13 Judo players and 13 non-athletes, in order to investigate the influence of long-term Judo training on both the bone mineral density and the predictive factor for cardiovascular disease. Using a mean comparative analysis, a correlation analysis, a regression analysis, and a relationship analysis, the measurement results are analyzed using SPSS/PC 20.0. According to the analysis results, the Judo players represent higher bone mineral density levels of the thighbone(p<.01), spine(p<.001), and body(p<.001) than the non-athletes in the mean comparative analysis between the Judo players and the non-athletes. In the case of the risk factor for cardiovascular disease, the Judo players represent higher levels of the muscle mass(p<.05) than the non-athletes but the non-athletes show higher levels of the triglyceride(p<.01) than the Judo players. Regarding the correlation of the bone mineral density and risk factor for cardiovascular disease, both the Judo players and the non-athletes represent a relatively high correlation level the bone mineral density and muscle mass(p<.01). In the multiple regression analysis results, the muscle mass(p<.01) represents the highest contribution to the bone mineral density. In the case of the relationship analysis for the groups that exhibit the lowest and highest bone mineral density, a large number of the Judo players are included in the high bone mineral density group. According to increases in the muscle mass subjects are distributed to the high bone mineral density group. Also, the low triglyceride group is largely included in the high bone mineral density group.
