This paper presents a framework of a optimal supervisory controller, which consists of decision rules and the supervisory controller proposed by Ramadge and Wonham. From the presented framwork we obtain optimal control patterns minimizing the given cost functions. The properties of the presented optimal supervisory controller are discussed. Two examples are given to illustrate a designing method of the optimal supervisory controller.

The objective of this paper is to provide an alternative framework for the integration of process planning and scheduling in cellular manufacturing. The concept of an integrated cellular manufacturing system is defined and the system architecture is presented. In an integrated cellular manufacturing system, there are three modules : the process planning module, the manufacturing-cell design module, and the cell-scheduling module. For each module, the tasks and their activities are explained.

어플리케이션 프레임워크는 객체 지향의 상속과 동적 바인딩의 특성을 기반으로 어플리케이션 전체 설계 개념의 재사용을 가능하게 한다. 어플리케이션 프레임워크에는 어느 특정 어플리케이션 도메인에 일반적인 비즈니스 객체, 사용자 인터페이스 객체, 저장소 객체 등의 다양한 객체들을 포함한다. 프레임워크를 기반으로한 어플리케이션의 개발을 프레임워크가 제공하는 이들 객체들에 대한 메타 저장소를 기반으로 해야 한다. 본 연구에서는 프레임 워크를 구성하는 이들 객체들을 정의하거나 재정의하는 데 필요한 환경을 제공하고자 한다.

The purpose of this study was to develop an instrument for assessing Korean mother's child rearing attitudes. The study attempted to explore dimensionality of maternal attitudes and formulated conceptual framwork. The items of maternal behaviour scale were tested on 300 mothers of 4th∼6th grade elementary school children living in urban areas. By the method of reliability analysis and factor analysis, 43 items were finally selected for the scale. The reliability of the new scale was ranged from .57 to .80. The construct validity of the scale was supported by the results of factor analysis.

In this paper, a new design technique called Task Based Design (TBD) is proposed to design an optimal robot manipulator for a given task. Optimal design of a manipulator is difficult because it involves implicit and highly nonlinear functions of many design variables for a complex task. TBD designs an optimal manipulator which performs a given task best, by using a framework called Progressive Design which decomposes the complexity of the task into three steps: kinematic design, planning and kinematic control. An example of TBD is presented to demonstrate the efficiency and effectiveness of our framework.

기존의 객체기술은 재사용성과 유지보수 측면에서 많은 문제를 안고 있다. 해결책으로 여러 가지가 제시되었으나 그 중 객체지향 프레임웍을 기반으로 하여 시스템의 복잡도와 급증하는 크기 그리고 개방형 시스템의 구축 시에 발생하는 여러 가지 난제를 해결하고자 하였다. 그러나 프레임웍 연구는, 대부분 컴포넌트나 객체단위의 재사용성을 극대화하는데 초점이 맞추어져 있어서 소프트웨어의 유연성(flexibility)에 관한 문제는 별로 다루어지지 않고 있는 것이 현실이다. 따라서 본 논문은 소프트웨어 시스템 아키텍쳐 수준에서와 유지보수 차원의 유연성을 확보하는 방안으로 '핫 스팟 어댑터 모델'을 제안하고자 한다.

The purpose of this study is to make a comparative analysis of the educational bojective, organization, contents, teaching and evaluation of the biological curriculum in high school of Korea and the United States. The results are summarized as follows: 1. In case of the educational objectives, both Korea and the United States emphasize the importance of the process of inquiry, experimentation and observation. Particularily, great emphasis is placed upon the human centered curriculum by reinforcing the relationships between the nature and human being. 2. In regard to the educational organization, eleven credit units(Science I: 5 credits, Biology: 6 credits) is allocated in Korea, and ten credit unit, in the United States. Both of Korea and United Stats designate the biology as elective course. But the science I course is designated as required in Korea 3. This study have been analyzed the educational contents of the two countries within the framwork of the basic concepts and essential informations contained in the curriculum. Results of the analysis as follow: The educational contents have less quantity and lower level in Korea than in the United States. And interrelations among the other curricula are not well considered in the curriculum of Korea/ On the other hands, interrelations among the oter curricula are fully considered and the purpose for emphasizing the importance of the process of inquiry course is well considered in the United States. The themes are stressed on "Structure and Function" (34.5%), "Genetic continuty" (21.3%), "Diversity and Unit" (14.2%) and "Regulation and Homeostasis" (10.3%) in Korea, and in the United States "Structure and Function" (27.3%), "Diversity and Unity" (25.6%), "Genetic continuty" (17.9%) and "Organism and Environment" (9.3%). 4. Regarding the educational guidance, both of Korea and the United States emphasis the interrelation of the basic concepts and principles within the total framwork. Also observation and experimentation, safety education, interest of students, life dignity, pretection of nature, social biology are reguired being paid special attentions. 5. In case of evaluation, both of Korea and the United States are the same in all of methods of evaluation. But the United States is grest stressed on reading and writing.

Recently, The medical services make use mobile healthcare system to transmit patient information on wireless environment. But It is difficult to satisfied for specified patient to send message, and it's not sufficient healthcare system to help regular treatment for example a diabetic or a pregnant woman. Thus, this paper proposes an healthcare scheduling application which manages a pregnant woman pregnant-checking, fetal movement sensing, antenatal training and promotion of health information using networking, data transmission method and application framwork of WPAN concepts.

점차적으로 소프트웨어의 복잡성이 증가함에 따라 소프트웨어의 재사용에 대한 요구가 증가하고 있다. 객체 지향 패러다임에서는 표준 인터페이스나 상속을 통하여 코드에 대한 재사용의 증가를 가져 왔다. 재사용이 가능한 부품들로 잘 정의된 클래스 라이브러리들은 코드의 재사용성은 매우 뛰어나지만 분석과 설계에 대한 재사용은 지원하지 못한다. 코드는 물론 분석과 설계의 재사용을 위하여 프레임워크의 개념이 생겨났으며 이를 상업적으로 구현한 제품이 등장하고 있다. 본 논문에서는 특정 애플리케이션 도메인에서 소프트웨어 재사용을 위해 프래임워크를 이용한 애플리케이션 개발을 지원하는 RAD(Rapid Application Development) 도구의 모형을 제안하고 각 서브 모듈의 기능과 데이터 흐름을 정의함으로써, 프레임워크를 이용한 애플리케이션 개발 도구의 구현을 위한 사전 설계 작업을 소개한다.
