생활수준이 향상되면서 물의 양과 질에 대한 국민의 요구수준은 높아지고 있으나, 우리의 하천유지유량은 일본의 1/3에 불과하며, 평갈수기의 하천유량 증대가 물관리의 주요 관심사로 떠오르고 있다. 댐 저수지의 저류와 생공용수의 회귀수에 의해 평갈수기의 하천유량을 크게 개선시킬 수 있는 바, 본 연구에서는 수계별로 그 현황과 향후 개선방안 도출을 위해 무수한 하천지점에서 용수수급 현황을 쉽게 분석, 평가할 수 있는 시스템을 개발하였다. 개발된 시스템은 용수수요 추정 모듈, 일 유출 모의 및 하천 유황분석 모듈, 기존댐 저수량 변화 모의 모듈, 신규 댐 규모 모의 모듈 등으로 구성되어 있다(그림 1). 분석 대상 하천 지점 유역의 논 용수, 생활 용수, 공업 용수의 수요량을 일별로 추정할 수 있으며, 이들의 회귀수를 고려한 하천유량을 일별로 모의하여 유황을 분석할 수 있고, 상류에 기존 댐 및 저수지가 있는 경우 이의 저수량을 모의하여 하류 방류량을 고려한 하천유량을 분석할 수 있고, 하천유황이 목표 값에 미치지 못하는 경우 신규 댐 및 저수지를 계획하여 이로부터 유량을 공급받아 하천유황을 유기적으로 아주 쉽게 분석할 수 있도록 하였다. 또한 저수량 변화 모의의 필수 자료인 저수지 표고별 저수면적, 저수량 자료를 신속하게 수집, 정리할 수 있도록 DEM을 활용하는 모듈을 장착하였다(그림 2). 수계별로 수많은 하천 지점의 유지유량 확보를 위한 다양한 용수공급 시나리오를 신속하게 분석, 평가하는데 편리한 도구로 활용할 수 있을 것이다. 개발된 시스템은 금강 유역의 하천유지유량 확보 방안 수립에 활용하고 있으며, 향후 전 수계에 적용될 수 있도록 보완할 것이다.

In this paper, we propose the new algorithm which can design on the optimal structure of modular system. This system is composed to the wavelet neural network in order to simplify the structure of modular system and use the time-frequency analysis. We will determine the number of module and node of each sub-system using the proposed algorithm. This algorithm provides the methodology, which we will design optimal structure of modular wavelet neural network through analyzing the character of system. We apply the proposed new structure and algorithm to approximation problem and evaluate the effectiveness of the proposed system and algorithm.

In this paper, a parallel processing system is proposed for improving the processing speed of image related applications. The proposed parallel processing system is fully synchronous SIMD computer with pipelined architecture and consists of processing elements and a multi-access memory system. The multi-access memory system is made up of memory modules and a memory controller, which consists of memory module selection module, data routing module, and address calculating and routing module, to perform parallel memory accesses with the variety of types: block, horizontal, and vertical access way. Morphological filter had been applied to verify the parallel processing system and resulted in faithful processing speed.

Object-Oriented design method decomposes the program into object that establish the relationship between objects. It is the technique of object centered decomposition unlike function oriented legacy system. Since existing Object- Oriented design method doesn't fully explain of the design method of module and decomposition, and need to implement the Object-Oriented software as a total system init. It has many problems that whole object design method and application programs should be analyzed for the understanding an Object-Oriented software component. Therefore, this study provides a procedure for Object-Oriented module design and criteria of decomposition to practically support the complex and large system development. Futhermore, it shows a consistency between design model and implementation through a case study applying these module decomposition criteria to the real system.

The controller area network(CAN) was originally developed to support cheap and rather simple automative applications, However, because of the its performance and low cost, it is also being considered in automated manufacturing and process control environments to interconnect intelligent devices, such as modem sensors and actuators. This paper presents a new application technology of the developed CAN control modules for the automated doors in building automation system Key pad and RF methods are used to open and close the automated door by the slave CAN module with CAN Protocol. BAS application technology of CAN field bus modules is also presented firstly in our nation.

Recently, modular structural systems have been applicable to building construction since they can significantly reduce building construction time. They consists of several unit modular frames of which each beam-column joint employs an access hole for connecting unit modular frames. Their structural design is usually carried out under the assumption that their load-carrying mechanism is similar to that of a traditional steel moment-resisting system. In order to obtain the validation of this assumption, the cyclic characteristics of beam-column joints in a unit modular frame should be investigate. This study carried out finite element analyses(FEM) of unit modular frames to investigate the cyclic behavior of beam-column joints with the structural influence of access holes. Analysis results show that the unit modular frames present stable cyclic response with large deformation capacities and their joints are classified into partial moment connections. Also, this study develops a simple spring model for earthquake nonlinear analyses and suggests the Ramberg-Osgood hysteretic rule to capture the cyclic response of unit modular frames.

본 논문에서는 시선인식을 이용한 지능형 휠체어 시스템에 대해 설명한다. 지능형 휠체어는 초음파센서를 이용하여 전동휠체어가 장애물을 감지하여 회피할 수 있게 하고, 조이스틱을 움직이기 힘든 중증 장애인을 위해 시선인식 및 추적을 이용하여 전동휠체어를 움직일 수 있게 하는 인터페이스를 제안한다. 지능형 휠체어는 시선인식 및 추적 모듈, 사용자 인터페이스, 장애물 회피 모듈, 모터 제어 모듈, 초음파 센서 모듈로 구성된다. 시선인식 및 추적 모듈은 적외선 카메라와 두개의 광원으로 사용자 눈의 각막 표면에 두 개의 반사점을 생성하고, 중심점을 구한 뒤, 동공의 중심점과 두 반사점의 중심을 이용하여 시선 추적을 한다. 시선이 응시하는 곳의 명령어를 사용자 인터페이스를 통해서 하달 받고, 모터 제어 모듈은 하달된 명령과 센서들에 의해 반환된 장애물과의 거리 정보로 모터제어보드에 연결되어 있는 두 개의 좌우 모터들을 조종한다. 센서 모듈은 전등휠체어가 움직이는 동안에 주기적으로 센서들로부터 거리 값을 반환 받아 벽 또는 장애물을 감지하여 장애물 회피 모듈에 의해 장애물을 우회 하도록 움직인다. 제안된 방법의 인터페이스는 실험을 통해 시선을 이용하여 지능형 휠체어에 명령을 하달하고 지능형 휠체어가 임의로 설치된 장애물을 효과적으로 감지하고 보다 정확하게 장애물을 회피 할 수 있음을 보였다.

Modular snake-like robots, which consist of series of modules, are robust for failure and have flexible locomotions for environment. However, they are difficult to control and few efficient and various locomotions are introduced yet. In this paper, GA based phase generation and trajectory generation approaches are implemented and compared for locomotion of snake-like robots and extended for analysis for selections of partial modules. In addition, modeling and simulation environments are implemented in Webots simulator and above GA based experiments for locomotion are executed for KMC snake-like robot.
