The second part of this study is to typify plural sexuality articulated with fashion images in men's and women's popular fashion magazines in Korea since 2000 and ultimately to infer sexual ideology codified in modern fashion by a framework of this study, the socio-semiotic model. From this, sexuality represented in modern fashion was typified as follows: in women's fashion Traditional Femininity, Glamor Femininity, Androgynous Femininity, Babydoll Femininity and Genderless sexuality, while in men's fashion Traditional Masculinity, Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity and Genderless sexuality. The conclusion of this study is as follows: First, modern fashion has been changed from a means expressing gender and class into a sign vehicle representing the new ruling system of age and sexual desire. The binary oppositional sexuality on center of man in the 19 C capitalist period has been gradually pluralized towards the post-capitalist period. Next, mainstream society in Korea is still positioned in the traditional heterosexuality, keeping the vertical power relationship between man and woman even in the post-modern period. However, the fact that both Traditional Femininity and Androgynous Femininity acquire the position of dominant femininity connotes the change of modern femininity. Finally, plural sexuality represented in modern fashion has family resemblance and it shows contextual flexibility within contemporary period as well as a historical context. As a result, sexuality floats with a specific historical and socio-cultural context, and fashion as a material culture represents a masquerade as a identity vehicle, which constructs and de-constructs sexuality at the same time.

다중 단면 재구성(MPR)은 삼차원 의료 데이터에서 사용자가 지정한 단면의 영상을 생성하는 볼륨 가시화 기법으로 의료영상 시스템에 필수적으로 이용되고 있다. 최근 의료영상 시스템의 발전으로, 사용자는 하나의 인체 데이터에 여러 단면을 위치시키고 이들 각각을 편리하게 제어하는 기능을 요구한다. 본 연구는 최근 MPR에 필요한 다양한 사용자 요구를 분석하고, 이에 적합하도록 좌표계를 제어하는 방법을 제안한다. 구체적으로, 가능한 사용자 조작을 모두 나열하여, 각 조작에 대해 단면의 움직임에 대한 요구를 분석한다. 또한, 이를 효과적으로 구현하기 위해, 각 단면을 별도의 좌표계로 다루고, 좌표계를 구성하는 정보를 독립 구성요소와 공통 구성요소로 나누어 처리하는 방법을 제안한다. 본 시스템은 그래픽스 가속기 상에서 구현되어 최근 요구사항을 포함하는 MPR 기능을 원활하게 수행할 수 있다.

In the satellite operation phase, a ground station should continuously monitor the status of the satellite and sends out a tasking order, and a satellite should transmit data acquired in the space to the Earth. Therefore, the communication between the satellites and the ground stations is essential. However, a satellite and a ground station located in a specific region on Earth can be connected for a limited time because the satellite is continuously orbiting the Earth, and the communication between satellites and ground stations is only possible on a one-to-one basis. That is, one satellite can not communicate with plural ground stations, and one ground station can communicate with plural satellites concurrently. For such reasons, the efficiency of the communication schedule directly affects the utilization of the satellites. Thus, in this research, considering aforementioned unique situations of spacial communication, the mixed integer programming (MIP) model for the optimal communication planning between multiple satellites and multiple ground stations (MS-MG) is proposed. Furthermore, some numerical experiments are performed to verify and validate the mathematical model. The practical example for them is constructed based on the information of existing satellites and ground stations. The communicable time slots between them were obtained by STK (System Tool Kit), which is a well known professional software for space flight simulation. In the MIP model for the MS-MG problems, the objective function is also considered the minimization of communication cost, and ILOG CPLEX software searches the optimal schedule. Furthermore, it is confirmed that this study can be applied to the location selection of the ground stations.

According to the conventional train control system, the area of each train is detected by plural track circuits located in a constant distance on railway lines in order to control a distance between trains. The conventional train control system has the difficulty in making use of the substructure thoroughly and transmitting enormous amount of information. To solve those problems, the wireless CBTC system has been a global issue. To apply wireless CBTC system to train system, the following two requirements are preferentially necessary: (1) Dualizing wireless CBTC system to control trains ceaselessly in a system accident, (2) Improving dependency of transmitted information for location and velocity to protect collision and derailment of lightweight trains in advance.

In order to design a stable robust controller, nominal model, and the upper bound about the uncertainty which is the error of the model are needed. The problem to estimate the nominal model of controlled system and the upper bound of uncertainty at the same time is called robust identification. When the nominal model of controlled system and the upper bound of uncertainty in relation to robust identification are given, the evaluation of the validity of the model and the upper bound makes it possible to distinguish whether there is a model which explains observation data including disturbance among the model set. This paper suggests a method to identity the uncertainty which removes disturbance and expounds observation data by giving a probable postulation and plural data set to disturbance. It also examines the suggested method through a numerical computation simulation and validates its effectiveness.

In this study, a predictive fuzzy control algorithm to supervise the elevator system with plural cars is developed and its performance is evaluated. The proposed algorithm is based on fuzzy in-ference system to cope with multiple control objects and uncertainty of system state. The control objects are represented as linguistic predictive fuzzy rules and simplified reasoning method is utilized as a fuzzy inference method. Real-time simulation is performed with respect o all possible modes of control, and the resultant controls ard predicted. The predicted rusults are then utilized as the control in-puts of the fuzzy rules. The feasibility of the proposed control algorithm is evaluated by graphic simulator on computer. Finallu, the results of graphic simulation is compared with those of a conventional group control algorighm.

Now it is reported that there are many companies and factories which confront to the problem of false alarm in Automatic Fire Detecting System (AFDS). Though an AFDS is a high-priced and very important device in detecting a fire. the problem degrades the reliability and utility, eventually faith. of the system. This is a research concerned about the problem of false alarm of fire detectors in an AFDS. Structure of detectors was modeled up as a general K out-of n system. and reliability characteristics including false alarm rate and missed alarm rate, are derived from it. For decision of an optimal structure of detectors. preliminary analysis on various criteria is accomplished. It is concluded that appropriate modification of a detector with plural sensors may increase the system reliability and decrease the false alarm rate.

When we measure the acoustical properties of a room using multiple microphone system, it is important to grasp exact time delay of the early reflections from impulse response pair. But it is often very difficult to identify the early reflections in natural shape, because a waveform may be deformed due to the characteristics of a sound source loudspeaker, microphone and reflected wall and overlapping of plural waveform. In this paper to obtain more accurate and enough early reflections, we propose the brand-new five-channel sound receiving system and introduce peak-detecting algorithm. The system has microphones mounted at the origin and four points of a regular tetrahedron. The newly introduced peak-detecting algorithm can show exact peak position in each channel, in spite of deformation due to reflected walls, loudspeaker and microphone.
