Fashion leadership of middle- and high-school male student was measured. The subjects were divided into five subgroups including, fashion dual leaders(13.3%), innovators(10.3%), opinion leaders(7.6%), followers(52.3%), and laggards(16.3%), according to their innovativeness and opinion leadership. The findings were as follows : fashion dual leaders were very confident and fashion-conscious while other subgroups were very price-conscious and quality-aware. Among the fashion information sources included in the study' my own experience and opinion' was the most Important to all 5 subgroups. Generally the higher the fashion leadership was, the more actively utilized fashion information sources. The fashion magazine and commercials as information sources was not as important to the subjects as it was to college women. Apparel shopping behavior was also significantly different among subgroups. As a whole, the general characteristics, such as. the use of fashion information and the apparel shopping behavior, of opinion leaders and innovators were similar, but those of followers and laggards were very dissimilar.

리더의 리더십이 팀 또는 조직의 효과성에 기여하기 위해서는 리더의 영향력을 구성원들이 수용하고 목표달성을 위해 노력하도록 구성원들을 동기부여시켜야 한다. 그런데, 리더의 영향력을 수용하고 추종하는데 구성원들간에 공유되어 있는 리더에 대한 표상에 리더가 일치하여야 한다. 이상적 리더에 대한 공유된 표상에는 그 사회문화에서 지배적인 가치규범이 중요한 역할을 하게 된다. 본 연구는 이러한 가치의 역할이 중요하다는 인식에 착안하여 한국인의 사고와 행동방식에 지대한 영향을 미쳐온 전통적인 유교적 가치에서 가정하고 있는 이상적인 인간상으로서의 군자를 현대 경영조직상황하에서 리더십의 관점에서 살펴볼 것을 제안한다. 이를 위해 사서(四書)-논어, 맹자, 중용, 대학에서 제시된 군자의 성격 또는 행동적 특징들을 내용분석하여 리더십 구조를 정의내리고 이를 측정할 수 있는 설문문장을 개발하였다. 그 결과, 군자리더십은 자기계발(思學), 인간존중(忠恕), 예절중시(禮), 공정함(義), 사람 관리의 5개 요인구조를 가지고 있음을 발견하였다. 추후 연구에서는 개발된 설문문항의 신뢰성과 타당성을 검증하고, 본 연구에서 개발한 군자리더십이 실제 경영조직에서 경영자의 리더십효과성을 잘 설명해주는 변별력 있는 개념인지 검증하는 노력이 필요하다. 이는 서양의 보편적으로 효과적인 리더십 유형, 예를 들면, 변혁적 리더십 유형과 같은 경쟁모형의 도입을 통해 보다 더욱 생동감 있는 측정이 가능할 것이다. 아울러 유교적 가치와 현대적 가치로 대변되는 합리성에 기반한 서구의 가치가 군자리더십과 어떤 관계를 가지고 있는 지 살펴 볼 필요가 있다.

The fuel pump system is developed with the Model Reference Adaptive Control (M.R.A.C.) algorithm based on the Weight Least Square (W.L.S.) algorithm for the parameter Identification and the one step ahead dead-beat control with the reference model. The value of some parameters as the sampling period 7, the weighting coefficient L, and the State Variable Filter (5.V,F.) coefficient f which a(fects the system performance are selected through computer simulation. For the variation of the plante dynamics rspecially due to the change of the fuel viscosity with the ambient temperature condition, the adaptability of the control system is studied in the case of regulation and tracking.

This paper describes to control system for AC to DC converter which has been widely used to power source in industrial factory and domestics. In this paper, three-phase PWM AC to DC Boost converter that operates with unity power factor and sinusodial input line currents is presented. The current control of this converter is based on the predicted current control strategy with fixed switching frequency and the line currents track to reference currents within one sampling time interval. By using this control strategy low ripples in the output current and the voltage as well as fast dynamic response are achieved with small dc link capacitance employed.ployed.

Among the autonomous driving systems based on visual sensors, the control method using a vanishing point is the most general method for autonomous driving. However, if the lane is lost or does not exist, it is very difficult to detect this and estimate the vanishing point. In this paper, we predict the vanishing point of the road and the vanishing point lines on the left and right sides using CNN for the camera image and design the steering controller for autonomous driving from the predicted results. As a result of the simulation, it was confirmed that the proposed method well tracked the center of the road regardless of the presence or absence of a solid lane, and was superior to the control method using a general method using the vanishing point.
