If a method of character region extraction will have general purposes, it could not but make use of common features which all target images have. This paper suggests these common features should be considered as the conditions for the region to be extracted within a framework of the cost minimization. The method suggested above could be effective by minimizing a cost function estmating the extent that character regions satify quantitatively the features, through Simulated Annealing Method. This method has an uniqueness in that it defines the cost function. Experimental results verify the usefulness of this cost minimization approach to character region extraction.

In this study, an seismic isolation system is suggested using a Natural Rubber Bearing(NRB) on a stainless steel water tank for stability assurance in an earthquake. A shaking table test was carried out to evaluate the seismic capacity of a non-isolated water tank and an isolated water tank. Displacement meters in the water tank measured the behavior characteristics of the tanks, which were compared using artificial seismic waves of 0.154g, 0.231g, 0.341g and 0.348g with water levels of 0.0m, 1.5m and 2.5m. At 2.5m, a decrement effect was generally shown in the isolated water tank, and a bigger displacement occurred in the non-isolated water tank than in the isolated one at water levels of 0.0m and 1.5m. It is interpreted that the weight of different water levels affects the decrement effect. If seismic reinforcement is done, the isolated bearing should be designed while considering the fluid storage level.

최근 들어 하천홍수위 증가에 따라 교량 하부 형하공간의 부족 등으로 인하여 다리밑 공간의 확보가 필요한 경우 기존 교량을 철거 후 재가설 하는 대신에 십자형 지지구조를 이용한 교량 상부구조 승상공법을 적용하여 기존 교량을 활용하는 방안의 적용이 증가하고 있다. 교량 상부구조의 승상공법 적용시 안전하고 연속적으로 인상작업이 가능하도록 유압·변위 자동제어시스템을 적용하였으며, 하부구조 콘크리트 타설 및 양생기간 중에도 영구 받침장치를 십자형 지지부재에 고정·설치함으로서 온도신축에 의한 구조거동에 대응할 수 있는 십자형 지지부재를 적용하여 교량승상을 안전하게 수행할 수 있음을 확인하였다.

In this study, a new STS lining method for reducing the number of dew condensation in the water tank was proposed, and the amount of dew water generated in the water tank before and after the improvement was verified through experiments. As a result of the dew condensation discharge experiment under actual environmental conditions for the existing lining water tank(A-type) and the improved STS lining water tank(B-type), the improved STS lining water tank(A-type) is the conventional lining water tank campared to A-type, an average of 1,428ml of condensed water was discharged, which was found to be 14times more effective.

지도학습은 방위학습, 기호학습, 위치학습, 축척학습 그리고 등고선 학습으로 구성된다. 이 중 등고선 학습은 지형의 기복을 약속된 규칙에 의해서 표현하고 이것을 다시 해석하는 학습영역이기 때문에, 단순히 이해에 머물지 않고 학습자의 공간능력을 요구하고 있다. 등고선 학습을 통하여 학습자는 지도로 표현된 2차원의 세계를 3차원의 세계로 다시 전환할 수 있는 능력을 키울 수 있으며, 이러한 능력의 개발을 통하여 기호로 표현된 도구(자료)의 공간적 시각화가 가능하고, 시각화된 공간의 오리엔테이션(방향전환)과 공간적 관계 파악이 가능하여, 기존에 잠재해 있던 공간 능력을 활성화 시킬 수 있는 계기를 마련하게 된다. 즉, 등고선 학습을 통하여 2차원의 세계를 3차원의 세계로 인식하는 과정은 학습자의 공간능력을 자극한다는 측면에서 중요한 교육적 의미를 지닌다. 본 연구에서는 그동안 등고선 학습에 도입되었던 다양한 방법들의 한계점을 보완하여, 지형도 2장과 2장의 판지를 이용한 입체지형 제작 방법을 제안했다. 한쪽 판은 홀수 등고선만 자르고, 또 다른 한쪽 판은 짝수 등고선만 잘라서 상호 교차하여 붙이는 방법이다(교차식 방법). 이 방법은 학습자들이 간단한 과정을 통하여 직접 제작할 수 있고, 등고선 위에 붙이기 때문에 등고선의 속성을 정확하게 이해할 수 있으며, 작업과정이 비교적 단순하여 1~2시간의 모둠별 수업 공간에서 해결이 가능하고, 재료가 적게 들어 비용부담이 적으며, 간단한 설명으로도 바로 작업에 임할 수 있다는 장점이 있다. Map learning is consists of the direction learning, the symbol learning, the location learning, the scale learning, and the contour learning. Especially, the contour learning has demanded the learners` spatial ability because it simply does not remain in the understanding about the relief of the terrain represented by the rules, but need to re-interpretation. Through the contour learning, the learner cultivate transform ability from the world of the two-dimensional to the three-dimensional. And it activate the spatial ability in existing opportunity that they have the potential to identify the spatial relationships. Eventually recognized as a three-dimensional world from the two-dimensional through contour learning process is simply does not remain in the understanding of the contours in the sense that stimulate the learners` spatial ability. That is an important educational significance. In this study, propose new method to make three-dimensional terrain, it compensate for the limitations of the various methods had been introduced in the learning contour, this new method(crossing method) is only using topographic maps 2 unit and cardboard 2 pieces. The attached to the cross-cut after one side is only cut the odd number and the other side cut the even number. It has advantage that the process is relatively simple and takes a little time and materials and space for working, only need a brief description for operation, and can be represented exactly according to contours. This new method has advantage in each learners to create their own terrain by themselves, can be solved within one or two hour of class time and can work normal classroom space of group learning, high accuracy, and low cost.
