The purpose of this study was to examine the effects of swimming participant"s achievement goal orientation and enjoyment on exercise addiction, and ultimately to provide the basic data on recreational swimmers and an opportunity to develop Sports-for-All. This study collected a total of 358 copies of questionnaires as its valid samples after giving out 430 copies of questionnaires. The collected data were analyzed through the SPSS Win Ver 18.0 statistical package program including frequency analysis, factor analysis, correlation analysis, t-test, One-way ANOVA, and multi-recurrence analysis. The results obtained from the above measures and procedures of this study are as follows. 1) There were partially significant differences in the variables of achievement goal orientation, enjoyment, and exercise addiction based upon demographic characteristics of swimming participants. 2) The achievement goal orientation of the swimming participants had a significant influence on exercise addiction. 3) The enjoyment of the swimming participants had a significant influence on exercise addiction. 4) The achievement goal orientation and enjoyment of the swimming participants had a significant influence on exercise addiction.

Electronic throttle control(ETC) is critical to drive ability, fuel economy and emission performance of present day passenger vehicles. Until now, many automobile engineer and company have been development electronic throttle controller and control algorism, such as adaptive control, sliding control, nonlinear and so on. But there are almost electronic throttle control using DC motor or stepping motor. This paper is the design of an electronic throttle controller and electronic throttle valve control using BLDC motor instead of DC motor.

본 논문에서는 축삭의 전도 현상을 분석하기 위해서 축삭을 전기전도 모델로 만든 후 여기에 키르히호프의 전류법칙과 전압법칙을 적용한 등가회로를 구성하였다. 축삭의 미세거리 변화에 의한 전위의 거동을 분석하기 위하여 축삭의 각종 파라미터를 구하였다. 검토결과에 의하면 무수신경인 경우 직경을 미지수로 하여 인체의 파라미터를 이용하면 그 속도는 직경의 제곱근에 비례한다. 한편 유수신경인 경우는 그 속도가 직경에 직접적으로 비례한다. 미엘린이 없는 막과는 달리 미엘린껍질의 전도는 전압과 무관하므로 이러한 막 양단의 Hodgkin-Huxley 형 전도모델이 매우 정교하지는 않다. I made the axon to the electrical transmission model and then constructed electrical equivalent model using Kirhhoff`s current law and voltage law in this paper. I calculated various axon parameters in order to analyze the electrical potential hehavior versus minute distance chang of axon. The transmission velocity of unmyelinated nerve is proportional to square root of axon diameter, while that of myelinated nerve is directly proportional to its diameter. Because the transmission of myelin sheath is independent of voltage unlike unmyelinated sheath, the Hodgkin-Huxley model across the membrane is not so precise.
