홍현기,최종수 중앙대학교 정보통신연구소 1999 정보통신연구소논문집 Vol.1 No.1

적외선 탐색기에 널리 사용되는 레티클 시스템은 시계(field of view ; FOV) 상에 존재하는 표적의 위치를 구하는 대표적인 방법이다. 본 논문에서는 동심원(concentric annular ring) 레티클 탐색기의 표적 추적 성능을 시뮬레이션 할 수 있는 효과적인 툴이 제안된다. 시계상에 섬광탄 등의 대응능력이 존재하는 경우, 표적에 대한 정확한 추적은 매우 어렵게 된다. 이러한 대응능력의 영향을 줄이기 위해 입력 신호와 기준 신호와의 상관 관계를 이용하는 반대응 기법이 제안된다. 구성된 툴 상에서 제안된 방법이 기존 방법에 비해 보다 효과적인 표적 추적 결과를 보임을 확인하였다. Reticle systems. which are widely used in infrared (IR) missile seekers, are considered to be the classical approach for estimating the position of a target in the field of view (FOV). This paper presents an effective simulation tool that gives tracking results of the concentric annular ring reticle seeker. Our simulation model provides tracking results in various cases, and is applicable to the study of the development of the advanced seekers. While false targets such as flares are presented in the FOV, simulation results show that the existing seeker cannot determine a precise target location. In order to decrease the susceptibility to countermeasures such as flares, we propose an efficient counter-countermeasure using the correlated relationship of modulated signals and the references. We have ascertained that the reticle seeker using our technique make more effective target tracking than previous seekers.

In recent years, fuzzy rule-based control systems have received more and more attention from both academic industrial researchers. Some researchers have developed approximate reasoning algorithms from the real-time control point of view. Among these algorithms, the one widely used in fuzzy control systems is the relational matrix model, which was first adopted by Mamdani and is based on Zadeh's compositional rule of inference. Taking account of the fuzzy nature of human decision making processes and real-time properties, this paper establishes a generalized approximate reasoning medel based on possibility theory rather than on relation matrix computation. The proposed algorithms are suitable for various definitions of linguistic connectives frequently used in fuzzy rule-based control systems. This paper also describes a fuzzy control application for dealing with the feasibility of the proposed method. Simulation results show that the process response can be controlled successfully by the proposed controller.

1. The aim of this study The aim of this study is to systematically research the teaching of physical education to mentally reatared children. The research includes a review of physical education programs for the mentally retarded, a study of the facilities available, and a presentation of the actual physical activities carried out in special education classrooms and schools. 2. The method of this study Written questionaries were distributed to sixty teachers teaching either special classes of retared children or in special education schools in the Chung Cheong Nam and Chung Cheong Buk Provinces. The sixty teachers were selected randomly. From the 60 questionsires returned four were not able to be used and so the final data is based upon 56 respondents. All the statistics are expressed as percentages. 3. The results The investigation of the actual state of physical education for retared children and the activities they engage in yielded the following information: 1) The nature, extent, and causes of of retardation are diverses and complex. Each child poses very special individual problems. For this reason it is difficult to design a single curriculum for physical education that will be suitable for all the children in a class. 2) Most of the retarded children come from the lower class. Their home environment is not good and dvelopment. It appears that the parents of trainable mentally retarded children are more interested in their child's development than are the parents of educable mentally retarded children. 3) The mentally retarded children are generally taught according to the syllabus for normal children ; but they should really be taught according to their own special needs according to their individual handicap. 4) The attitude of the mentally retarded children toward physical education is good. The educable mentally retarded children prefer physical activities like gmaes and sports, whereas the trainable mentally retarded children prefer more passive activitities like recreation and dancing. 5) Physical facilities for mentally retarded children are deficient. Facilities must be developed as soon as possible. Facilities that now exist in special schools are not well used because of the lack of specially trained physical education teachers. It seems to me that an awareness of the importance ofphysical education for the retarded is lacking. 6) Physical education teachers' co-operation and the development of special physical education methodology are lacking. The development of special physical education programs for mentally retarded children is an urgent issue. In light of the results outlined here, it is clear that the place of physical education in special education has not been professionally developed. The importance of physical education for mentally retarded children has not been understood and the result is that their education has a serious lack.

A new neural network structure called Self-Organized Distributed Networks (SODN) is proposed for developing the neural network-based multi-dimensional system models. The learning with the proposed networks is fast and precise. Such properties are caused from the local learning mechanism. The SODN is a hybrid structure of a learning network and a distribution network. The learning network is composed of a set of subnetworks while the distribution network composed of a set of self-organized units. With this structure, the SODN provides a better interpolation than the conventional locally distributed networks (especially RBF networks). In this paper, comparisons with multilayer neural network and RBF networks have been done through learning of two dimensional terrain elevation data.

The role and the function for the modern people are being deversified and varied in many ways owing to the material culture. With the representative books selected for the definite period, the wants I have considered the variation of the leisure are follows; 1) Accordign to the industrialization, the working hour is decreasing and leisure time is increasing, but the activity for this situation is not enough. 2) Female sex has more leisure time than male sex, but the leisure activity for female is wanting. 3) the ones who are over thirties have more leisure time than any other ages. 4) There are much different quantities of leisure time according to the kind of their vocation, so the leisure activity program for his own job is necessary. As a result of my studying for these situations. I have got the follwing conclusions. 1) The need for sports and creative recreations increasing. 2) Male is sleeping much time in sports, travel, and other activities, but female is spending her time in sleeping and domestic chore. 3) More educated people are enjoying more creative activities and sports, but less educated people are spending their time in sleeping, domestic chore, and watchig TV. A rural area has worse leisure time than a urban one an this present situation has been depended in the modernization of korea. Therefore the betterment should be made after due consideration of the difference of leisure time and quality of leisure action.

This study is a survey of development methods of sports activity for life sports which was conducted with questionaire of 17 items during the months of January and February 1985. The selection of subjects is based on the random sampling method, and 1928 ?? of the questionaire were distributed to the Chung-Buk inhabitants during the period from March to June 1985. Among them 1622 sheets(84.1%) were returned, and 142 ?? which made an error in answers were all removed, and 1480 sheets were turned into effect. This research, aimed the the investigation and expansion of sports to the ??of socity, obtained the following conclusions. 1. The necessity and recongnition of life sports is unknown generally. The design and conduct of any fitness program for populace adults must consider age and physical characteristics, envirommental condition and must act any support under the new system with the manager, local administration, a territorial society. Also, the goal of the program should emphasize self-improvement within the physical status of the participant, rather than the attainment of fitness levels based upon the norms or the achievments of population samples. 2. The contents of activition in sports have general a tendency to complication and diversity. There were no sufficient facilities and equipments of sports. Therefore, In order to achieve the expansion of sports to the lowest stratum of society, must be improved various environmental conditions that consist of extrinsic motivation and concrete project. 3. The items of sports must be improved on the based of interest, age, local charac-teristics and sports facilitie must be expanded for to health, welfare of one's place of work and enterprise.
