지방자치시대를 맞이하여 진정한 지방분권화를 이루기 위해서는 일정 행정 수준의 자주재정 확립이 보장되어야 한다. 현재 우리나라에서는 지방정부가 안고 있는 수직적 $\cdot$ 수평적 재정불균형 문제를 해소하며, 국가차원의 지역균형발전 및 행정의 효율성 및 효과성을 확보하기 위한 수단으로 지방재정조정제도를 시행하고 있다. 지방재정조정제도는 지역 간의 세원편재와 재정불균형의 시정을 통한 지방자치단체의 일정 행정 수준(national minimum standard)을 확보할 수 있도록 재원을 보장해주며 합리적이고 효율적인 제도 운영이 중요하다. 본 연구에서는 지방재정조정제도의 두 가지 수단인 지방교부세와 국고보조금에 대하여 알아보고 재정력이 취약한 자치단체의 재정형평성에 기여할 수 있는 개선방안을 제시하였다. 지방교부세와 국고보조금의 배분방식과 운영형태 등을 조정하여 형평성 원칙에 맞게 운영해 나가야 할 것이다.

This paper concerned about a imputed color printed material image in camera to decrease noise and distortion by processing median filtering with input image to identical condition. Also this paper proposed the way of compares a normal printed material with an abnormal printed material color tone with trained a learning of the error back-propagation to block classification by extracting five place from identical block(3${\times}$3) of color printed material R, G, B value. As a representative algorithm of multi-layer perceptron the error Back-propagation technique used to solve complex problems. However, the Error Back-propagation is algorithm which basically used a gradient descent method which can be converged to local minimum and the Back Propagation train include problems, and that may converge in a local minimum rather than get a global minimum. The network structure appropriate for a given problem. In this paper, a good result is obtained by improve initial condition and adjust th number of hidden layer to solve the problem of real time process, learning and train.

The purpose of this study was to analyze the historical development of high-rise buildings-promoting policies in Seoul in terms of modern urban redevelopment. The results of this study were as follows; The maximum height of the buildings has been limited by National codes since 1934. But at the same time, Seoul Metropolitan government had limited the minimum building floors of roadside buildings through local regulations after the Korean War. The high-rise city had been regarded as a means of beautifying Seoul for a long time. However since the 2000s, the minimum height limit for buildings was removed from local regulations and the concept of high-rise restrictions was no longer significant as before.

We build a local minimum free motion planning for mobile robots considering dynamic environments by simple sensor fusion assuming that there are unknown obstacles which can be detected only partially at a time by proximity sensors and can be cleaned up or moved slowly (dynamic environments). Potential field is used as a basic platform for the motion planning. To clear local minimum problem, the partial information on the obstacles should be memorized and integrated effectively. Sets of linked line segments (SLLS) are proposed as the integration method. Then robot's target point is replaced by virtual target considering the integrated sensing information. As for the main proximity sensors, we use laser slit emission and simple web camera since the system gives more continuous data information. Also, we use ultrasonic sensors as the auxiliary sensors for simple sensor fusion considering the advantages in that they give exact information about the presence of any obstacle within certain range. By using this sensor fusion, the dynamic environments can be dealt easily. The performance of our algorithm is validated via simulations and experiments.

The major operations of Evolutionary Computation include crossover, mutation, competition and selection. Although selection does not create new individuals like crossover or mutation, a poor selection mechanism may lead to problems such as taking a long time to reach an optimal solution or even not finding it at all. In view of this, this paper proposes a hybrid Evolutionary Programming (EP) algorithm that exhibits a strong capability to move toward the global optimum even when stuck at a local minimum using a synergistic combination of the following three basic ideas. First, a "local selection" technique is used in conjunction with the normal tournament selection to help escape from a local minimum. Second, the mutation step has been improved with respect to the Fast Evolutionary Programming technique previously developed in our research group. Finally, the crossover and mutation operations of the Genetic Algorithm have been added as a parallel independent branch of the search operation of an EP to enhance search diversity.

This paper presents an escaping route method in a trap situation (a case that the robot is trapped in a local minimum by the potential of obstacles). In this scheme, the APFs for path planning have a multiplicative and auditive configuration between APFs for goal destination and APFs for obstacle avoidance unlike conventional configuration where APFs for obstacle avoidance is added to APFs for goal destination. The virtual escaping route method is proposed to allow a robot to escape from a local minimum in trap situation where the total forces composed of repulsive forces by obstacles and attractive force by a goal are zero.

This paper proposes a process using the load shedding scenario method that determines the minimum local load shedding quantity considering the local DLC(Direct Load Control) potentials. So this method is applied to Kyung-In area and determined the load shedding of this area with comparison to its DLC potentials.

음성 인식에서의 dynamic time warp(DTW)은 반복적 계산을 필요로 하며, 이 계산을 수행하기에 합당한 PE cell의 설계는 매우 중요하다. 따라서 이 연구에서는 실제에 가까운 실시간 어휘 인식을 가능하게 하는 large dictionary 의 DTW 알고리즘을 hardware로 구현하기 위한 PE(Processing Element) cell의 설계에 주안점을 두었다. 이 DTW 용 PE cell은 크게 세가지의 블록으로 대별된다. 즉 MIN block, ADD block 그리고 ABS block인데, "MIN"은 accumulated minimum distance를 계산하기 위한 블록이고 "ADD"는 이들 minimum distance들의 합을 계산하는 블록, 그리고"ABS"는 이러한 합에 의한 local distance의 절대값을 구하기 위한 블록이다. 본 연구에서는 이들 세가지 블록중 MIN 회로의 설계 및 검증을 행하였으며, 3um CMOS N-well 설계 규칙에 따라 MIN 블록에 대한 레이아웃을 행한 후 설계 규칙 검사(DRC)를 마쳤다.레이아웃을 행한 후 설계 규칙 검사(DRC)를 마쳤다.

In this paper the Individual tap - Least Mean Square(IT-LMS) algorithm is applied to the adaptive multipath channel equalization using hybrid-type Genetic Algorithm(GA) for achieving lower minimum Mean Squared Error(MSE). Owing to the global search performance of GA, LMS-type equalizers combined with it have shown preferable performance in both global and local search but those still have unsatisfying minimum MSE performance. In order to lower the minimum MSE we investigated excess MSE of IT-LMS algorithm and applied it to the hybrid GA equalizer. The high convergence rate and lower minimum MSE of the proposed system give us reason to expect that it will perform well in practical multi-path channel equalization systems.

무선 센서 네트워크에서 네트워크의 확장성과 효율성을 높이기 위한 방법으로 네트워크 구조를 계층적으로 구성하는 방법에 관심이 높다. 무선 네트워크를 계층 구조로 구성하는 방법은 특정 노드들을 선별하여 이들을 백본 네트워크로 구성하는 방법을 중심으로 연구가 진행되었다. 백본을 구성하는 노드들은 연결되어 있어서 자신들 간에 통신이 직접적으로 가능해야하며, 백본에 속하지 않은 모든 노드들이 백본을 통해 통신이 가능해야한다. 이러한 조건을 만족하는 최소 크기의 노드 집합을 선출하는 문제를 최소연결지배집합선출 문제라 한다. 최소연결지배집합선출 문제는 복잡도가 NP-hard로 알려져 있으며, 현재 효율적인 알고리즘이 존재하지 않는다. 본 논문은 최소연결지배집합선출 문제를 해결하기 위한 다중시작 지역탐색 알고리즘을 제안하다. 제안 방법의 성능 측정을 위해 다양한 조건에서 실험하고 결과를 제시한다.
