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.

Biot수를 고려한 균일두께의 환상휜에서의 과도열전달에 관한 연구

김광수,Kim, Kwang-Soo 대한설비공학회 1985 설비저널 Vol.14 No.2

The heat diffusion equation for an annular fin is analyzed using Laplace transformations. The fin has a uniform thickness with its edge heat loss and two temperature profiles at the base such as a step change in temperature or heat flux. To obtain the exact solutions for temperature distribution, this paper can detect the eigenvalues which satisfy the roots of transcendental equations in above two cases during inverse Laplace transformations. The exact solutions for temperature and heat flux are obtained with the infinite Series by dimensionless factors. The solutions are developed for small and large values of times. These series solutions converge rapidly for large values of time, but slowly for small.

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.

As recently, 'International convention for the control and management of ship's ballast water and sediments' was adopted, it is necessary to accept the international convention in Korea The movements of foreign countries for ship's ballast water control and management were investigated, and domestic environment-related laws were reviewed and compared regarding the discharge of industrial wastewater and ship's ballast water. Alternative measures of domestic legislation were suggested for acceptance of the international convention. 최근에 "선박의 밸러스트수와 침전물의 제어 및 관리를 위한 국제협약 "이 채택되면서 국내에서도 이 국제협약을 수용하기 위한 방안이 필요하다. 외국의 밸러스트수 제어/관리 동향을 살펴보고, 국내의 환경관계법규들을 비교$\cdot$검토함으로써 밸러스트수관리협약을 수용하기 위한 국내 입법화 방안을 제시하였다.

In this paper, temperature distributions in radial fin of hyperbolic profile for steady -state with no heat generation are obtained by one-dimensional analytical method, finite difference method and experiment respectively. Heat flow rate and fin efficiency from the fin model are obtained by analytical method. To compare the exact solutions obtained by theoretical analysis with the results obtained by finite difference method, cylindrical shape is selected. Particularly, equations of finite difference method for cylindrical shape with irregular boundary are rearranged and formulated. Consequently, temperature distributions in radial fin can certify that are similar to exact solutions. From theoretical analysis, the effects according to heat flow rate and fin efficiency are related to variation of parameters which are fin thickness ${\delta}_o$, fin base temperature $T_o$, thermal conductivity K with same basic dimensions and the fleets are studied and compared.
