컴포넌트 소프트웨어의 가장 큰 장점은 응용 소프트웨어사이의 컴포넌트 재사용이다. 본 논문에서는 컴포넌트 재사용의 장점을 지리정보시스템 분야에 접목하여 지방자치단체에서 지리정보시스템을 빠르고 효과적으로 구축하기 위한 컴포넌트의 설계와 구현 방법을 설명하였다. 구현된 컴포넌트는 응용 서비스 컴포넌트로 부산시에서 1999년도에 수행한 사업과 1999년과 2000년에 개방형 GIS 컴포넌트 S/W 개발 과제의 결과물을 기반으로 지방자치단체에서 수행하는 서로 다른 업무 사이에 공통적으로 적용 가능한 기능을 도출하여 구현하였다. 분석 대상이 된 업무는 지방자치단체에서 지리정보시스템으로 구축하는 빈도가 높은 상수도관리 업무, 하수도 관리 업무, 도로 관리 업무, 도시 계획 업무, 지적 관리 업무이다. 분석 과정을 통하여 5개의 업무들 사이에 11개의 공통 기능을 추출하였으며 이 중 7개의 기능을 5개의 응용 서비스 컴포넌트로 구현하였다. 구현된 컴포넌트는 Authority, GISReport, MapService, SymbolManager, AttributeDisplay등 5개로써 사용자 관리, 측정, 검색, 출력, 인덱스 창, 심볼 관리, 속성 정보 표현, 출력 등의 기능을 수행한다. The advantages of using components result from their reusability between applications. Applications can be easily implemented by adding components. In this paper, we described the design and implementation process of ASC(Application Service Component) for component-based GIS applications. In our project, there are 5 applications : Road Facility Management, Urban Planning, Cadastral Map Management, Water Supply Management, and Sewerage Management. All of them use MapBase component which supports common GIS functionality. Although they are different applications, some parts of them are same. We analyzed the developed results in 1st and 2nd year, and the achievement of UIS(Urban Information System) project in Busan Metro City in Korea. The UIS of Busan was consisted of 5 applications to equal with our project. Then, we extracted 11 common used components between 5 applications, and implemented 5 common components of them and 2 additional components. They were Authority, GISReport, IndexMap, Measurement, Search, Symbol Manager, and Attribute Display. As we offered them to companies developing application components, they were able to reduce the development time.

Present study is concerned with an experimental study on the cooling characteristics of heat-generating components arranged in channels which are made by printed circuit boards. To assess the thermal performance of the heat-generating components arranged by $5\times11$ in flow channel, three variables are used: the velocity of the fluid at the entrance, the height of channel, and row number of the component. The cooling characteristics of the heat-generating components such as the surface temperature rise, the adiabatic temperature rise, the adiabatic heat transfer coefficient, and the effect of thermal wake are compared with the result of the experiment and the numerical analysis. Based on the experiment analysis, some conclusions can be drawn: First of all, the experiment and numerical analysis are identical comparatively; the heat transfer coefficient increases as H/B decreases. Howeve., when H/B is over 7.2, the effect of H/B is rather trivial. The effect is the biggest at the first component from the entrance, and it decreases until the fully developed flow, where it becomes very consistent. The thermal wake function calculated for each row decreases as H/B increases.

This paper treats the temperature effectiveness of the two-fluid counterflow regenerator in a rotary type. To avoid continual interpolation and to obtain the simple result in calculating that, it obtained the particular solution for the direct-transfer-type counterflow heat exchanger by the graphical procedures. Also, it introduced the empirical formula for the influence of the ratio of rotor matrix to minimum working fluid heat capacity rate with the particular solution induced. Particularly, substituting the published results of temperature effectiveness into the program, it obtained the simple and convenient equation which can applicate in the counterflow regenerator in a rotary type. To compare and discuss the results induced, selecting the regenerative air preheater and applying the their running datum and specifications to the related results, it shows that the above results are agree with the published results within absolute relative error, 3.0%.

One of the most important and powerful tools available for design and/or study of the operation of complex systems and processes is simulation. Since automated material handling systems like AS/RS are often quite complex, a network-based simulation model is developed to analyze an automobile part supplier's automated storage and retrieval system(AS/RS). The network simulation model is implemented in the SLAM Ⅱ on a VAX 8800 computer. Performance of the AS/RS was tested for 3 dispatching rules, 3 work load levels, 2 storage policies, 3 levels of stacker crane break-down, and 2 conveyor system layouts. Results indicate that the AS/RS performance is primarily affected by the dispatching rule and work load level.

This study conducts an analysis for the heat diffusion of an annular fin considering con-vection phenomena at the fin edge as well as along the fin perimeter. When the temperature of the fin base is given with an increasing exponential function, the exact series solutions of tem-perature distribution are obtained by laplace transformation in terms of dimensionless para-meters. From these solutions heat flux and fin efficiency can be obtained. These exact solu-tions converge rapidly for large values of dimensionless time, but slowly for small ones. To avoid this convergence difficulty, approximate solutions of the temperature distribution and heat flux for small values of dimensionless time are also presented. Substituting the variations of dimensionless parameters into the these exact solutions, the characteristics of these response are investigated.

An experiment was conducted to compare the adsorption capacity and characteristics between activated carbon made of rice-hull(RHAC) and F-400 by Calgon to remove phenol, heavy metal and ammonia-nitrogen. While F-400 could not remove ammonia-nitrogen, RHAC was able to adsorb it. This is considered to be due to the ion exchange capability of SiO₂ remaining on the surface of RHAC. From the isotherm equilibrium test, it was found that RHAC has higher adsorption capacity than the existing activated carbon. In column tests, however, the slope of breakthrough curves of RHAC which represent the affinity of adsorbent, was observed to be more gradual than F-400. This may be attributed to the competitive reaction between ion exchange and physical adsorption. For heavy metals, F-400 would remove Cr and Pb except Cd, whereas RHAC was able to remove Cd, Pb except Cr.

This study was performed to compare the shear strength of the bondings between stainless steel crown/direct type composite resin and stainless steel crown/indirect type composite resin. Four groups of bonding conditions were prepared. Two groups of bonding conditions were made by the indirect type composite resin system and the other two groups were made by the direct type composite resin system. The shear strength tests were carried out using universal testing machine, Model 4465 of Instron Co.. It was indicated that the bond strength values of the indirect type composite resins were higher than those of the direct type composite resins. TE-SE group was superior to the TE-ONE in indirect type resin system. These results were thought to be the high degree of the polymerization accompanied with temperature and pressure of the resin of indirect type resin. It was also found that indirect composite resin contains less amount of porosity in resin.
