A new approach considering CO2 air pollution constraints in the long-term generation mix is proposed under uncertain circumstances. A characteristic feature of the presented approach in this paper is what effects give the air pollution constraints in long term best generation mix. Best generation mix problem is formulated by linear programming with fuel and construction cost minimization with load growth, reliability (reserve margin rate) and air pollutionconstraints. The proposed method accommodates the operation of pumped-storage generator. It was assumed in this study that the construction planning of the hydro power plants is given separately from the other generation plans. The effectiveness of the proposed approach is demonstrated by applying to the best generation mix problem of KEPCO-system, which contains nuclear, coal, LNG, oil and pumped-storage hydro plant multi-years.

Our school management is changing by soft and self-regulating method from single educational system. Especially, 7th educational curriculum demands change of educational system and operation that correspond spontaneously on various needs of students. Like this, changing educational policy and curriculum accompany change of social awareness, curriculum, and school space should be changed corresponding hereupon. Such our change can say that is appearing fairly similarly, when compare in Japanese educational policy, curriculum, side of change of school space. Because it is resulting from partial accepting of educational curriculum, system, school architecture and space of Japan. In such background, I investigates Japanese schools cases that advanced than us, which is been opened within the latest 6 years. Through this analysis, I find space and function that can apply to our school. And I will propose some basic data needed for educational and architectural planning side.

In this paper, we present an agent-based transportation routing method in a semi-conductor production line. The main characteristic of the proposed method is that each AGV agent individually searches candidates of its route with reference of the pheromone information based on the use of an analogy of Ant System. The proposed method is applied to several routing problems. The performances of the proposed method are compared with those of a Genetic Algorithm. The effectiveness of the proposed method is conrmed by many numerical examples. In order to demonstrate the effectiveness of the proposed method for an actual problem, the proposed method is applied to a dynamic motion planning. The proposed method ...

The objective of the study is to know demographic characteristics mobility motivation housing aspiration and housing values of expected purchasers of the small/medium size apartments located at 'H-area' in Ulsan to enhance their level of housing satisfaction through better planning. The result shows that moving motivation housing aspiration and housing values differ as what size respective expected purchasers want. As a regional characteristic the reality-oriented view of housing is apparent in that their interests are focused on the setups or facilities after-service and maintenance and that they think conveniency more important than the edifices' appearance or beauty.

Proper pretest planning is a vital component of any successful vibration test on engineering structures. The most important issue in dynamic testing of many engineering structures is arriving at the number and optimal placement of sensors. The sensors must be placed on the structure in such a way that all the important dynamic behaviour of a structural system is captured during the course of the test with sufficient accuracy so that the information can be effectively utilised for structural parameter identification or health monitoring. Several optimal sensor placement (OSP) techniques are proposed in the literature and each of these methods have been evaluated with respect to a specific problem encountered in various engineering disciplines like aerospace, civil, mechanical engineering, etc. In the present work, we propose to perform a detailed characteristic evaluation of some selective popular OSP techniques with respect to their application to practical civil engineering problems. Numerical experiments carried out in the paper on various practical civil engineering structures indicate that effective independence (EFI) method is more consistent when compared to all other sensor placement techniques.

The catenary system supported by the tunnel bracket which has been used uniquely in KNR was selected as the catenary inside narrow existing tunnel in the electrification of Kyeung-Bu Line for operation of Korea High Speed Train(KTX). It was demanded to judge the maximal operable speed of KTX in this catenary system to implement the planning. To do this, the tunnel bracket was firstly tested to obtain the characteristic data. The stiffness of this bracket are computed depending on the location which catenary installed on. Moreover, the catenary using tunnel bracket is modelled numerically respecting the bracket stiffness. Based on these, the dynamics between this catenary and KTX pantograph are simulated with the program developed by ourselves independently. The simulation result are evaluated according to the generally acceptable criteria. Consequently, the maximal operable speed of KTX in the catenary using KNR(Korean National Railroad) tunnel bracket is predicted and some items which are needed to be kept in the processing of implementation are drawn.

The purpose of this study is to develop the life scale of the middle aged homemakers. The life scale are composed of spouse relation 8 items, child education relation 7 items, home economy relation 4 items, homework relation 3 items, selfish health relation 6 items, parent relation 3 items, and interest and social activity relation 4 items. The reliability coefficient of the development scale was Cronbach'α =.83 and the correlations of each demesne was high. For the better future life in this study, the middle aged homemakers are needed the improvement of conjugal relations, the child education, the health, the interest, and the enlargement of social relations. This life scale can help to evaluate their middle age, and to the planning of energetic healthful future, and useful to understanding characteristic and the developmental task of middle aged homemakers.

최근 몇 년 동안 몇몇 환경에서 트래픽 패턴이 Poisson 패턴보다 Self-similar 패턴에 더 가깝다는 것이 입증되어 왔다. 본 논문에서는 이러한 Self-similar 확률과정의 정의 및 트래픽의 특성, 그리고 최근 논문들에서 보고된 사례에 대해서 고찰해 봄으로써, 실제의 이동전화 데이터 트래픽 특성에 적합한지를 응용하고자 한다.
