19세기 西進東漸의 파도 속에서 국가의 자립과 근대화를 위해 몸소 힘썼던 兪吉潛과 福澤??論의 사상 가운데 그들의 政淪論을 한국과 일본의 근대화 방향 차이를 중심으로 살펴보고자 한다. Due to the friction characteristics of pump, cylinder packing and passenger car, in the elevation system actuated with hydraulic inverter, there exist dead zones, which cannot be controlled by a PID controller. To overcome the drawbacks, in this paper, we propose a new hybrid fuzzy-sliding mode control scheme, which controls the controller output between a sliding mode control output and a PID control output by fuzzy control method. The proposed hybrid control scheme achieves an improved control performance by using both controllers: We first propose a design method of the hybrid controller for a hydraulic system controlled by inverters, then propose a design method of a hybrid fuzzy-sliding mode control scheme. The effectiveness of the proposed control scheme is shown by simulation results, in which the proposed hybrid control method yields better control performance then the PID controlled scheme, not only in the zero-crossing speed region but also in the overall control region including steady-state region.

유압식 인버터 엘리베이터의 속도제어를 위한 하이브리드 퍼지제어기의 설계

인버터를 적용한 유압식 엘리베이터 시스템은 펌프의 마찰과 실린더 패킹 및 탑승카와 레일의 마찰특성으로 인하여 PID 제어기로는 제어가 되지 않는 데드존이 생기게 된다. 본 논문에서는, 이러한 문제를 해결하기 위하여 먼저, 퍼지제어기와 PID제어기를 혼용하는 하이브리드제어기를 이용하는 방법을 시도한다. 그러나, 인버터를 적용한 유압식 엘리베이터는 비선형성이 강한 시스템이므로 두 제어기의 출력이 절환 되어야 하는 경계층이 다수인 경우가 대부분인데 반하여, 기존의 하이브리드제어기는 두 제어기의 출력이 절환되는 특정구간의 경계층을 제외하고는 전체 운전구간에서는 어느 한 제어기에만 영향을 받게 되므로 제어성능에 문제를 가지게 된다. 이에 따라 본 논문에서는, 출력혼합기의 출력비를 퍼지로직에 의하여 변경시키는 새로운 퍼지하이브리드제어기를 제안하여 기존의 하이브리드제어기의 문제점을 해결한다. 제안된 퍼지하이브리드제어기는 시스템의 상태에 따라서 두 제어기의 출력비를 달리하여 사용하는 방법으로 향상된 제어성능을 달성한다. 시뮬레이션 결과를 통하여, 제안된 퍼지하이브리드제어기가 극저속 속도영역에서 뿐 아니라 정상상태를 포함한 전 운전 영역에서의 제어 성능이 우수함을 보였다. Due to the friction characteristics of cylinders and the rail of a passenger car, in the elevator actuated with hydraulic systems, there exist dead zones, which can not be controlled by a PID controller. To overcome the drawbacks, in this paper, we first try a hybrid controller which switches between a fuzzy logic controller and a PID controller. However, because the hybrid control scheme uses only a single type controller, except the switched layer, the high control performance can not be achieved. To solve this problem, we propose a new type fuzzy hybrid control scheme, which outputs of the output mixer arc controlled by a fuzzy logic. The hydraulic elevator system controlled by inverters has more then one switched layers due to the highly nonlinear characteristics. The proposed fuzzy hybrid control scheme achieves improved control performances by using both controllers with weighted outputs depend on the system status, to achieve improved control performances. The effectiveness of the proposed control scheme arc shown by simulation results, which the proposed fuzzy hybrid control method yields good control performance not only in the zero crossing speed region but also in the overall control region including steady-state region.

sports for all aims st helping people enjoy healthy everyday life and at enriching morality and emotion for good citizens. They provide people with an opportunity to have a healthy life regardless of class, gender, and age. is inertial, therefore, that sports for all in the local level should be activated. plans for encouraging sports for all in the era of localization 1. The shift in consciousness for sport and recreation activities is needed. 2. Through an adjustment and change of administrative structures and organizations in local sports activities, Bilateral cooperation system between central organization and local organization for the is needed. 3. encouragement of investment of private enterprises and local inhabitants to invest, the expansion of sports facilities is needed. 4. Suitable programs development and supply in proper communities are needed. 5. All sports establishments and organization should have qualified social athletics leaders. 6. Various and appropriate financial resources are needed. 7. Interdependent relations between community athletics and school athletics are needed. 8.

To develop the relationship study between lifestyle satisfaction of school and motivation of participation into taekwondo of the adolescents, this study was foused to develop the relationship among subscales of lifestyle satisfaction of school-committee of lifestyle satisfaction of school, satisfaction of department of school, and satisfaction of school environment and motivation of participation-emotional motivation, hobby motivation, physical motivation and social motivation of the adolescents. The study tool for measuring lifestyle satisfaction of school was a 5 point Likert Scale qusetionnaire adjusted for this research propose developed by sung-hee, Cho(2001) and chae-hee, Lee(2000). Analysis was done by the Multiple Co-variate Anlysis Method. The results of this study was a follows: Firstly, There was showed relationship between committee of lifestyle satisfaction of school and motivation of participation in taekwondo of the adolescents. Secondly, There was showed relationship between satisfaction of department of school and motivation of participation in taekwondo of the adolescents.

The purpose of this study is to determine how a Taekwondo player's athletic satisfaction affects his/her psychological health and overall personal happiness. A questionnaire survey was carried out on a sample group of 200 students attending colleges located in Seoul and Gyeonggi Province. Then, 23 questionaries deemed not trustworthy were eliminated, leaving 178 questionaries for analysis. The questionnaire, which contained total 128 questions, showed the confidence level falling between .5241 and .8945 (Cronbach's alpha). The study, which relied on frequency analysis, t-test, One-way ANOVA, and Scheffe test, produced the following results. First, athletic satisfaction showed a statistically significant difference (5% range) depending on sex, school year or athletic experience. Second, psychological health resulted in a statistically significant difference (5% range) depending on sex or athletic experience while no difference was noticed regarding school year. Third, happiness in life showed a statistically significant difference (5% range) depending on sex or school year while no difference was noticed with regard to athletic experience.
