지방자치단체 지리정보시스템에서 재사용을 위한 응용 서비스 컴포넌트의 설계 및 구현
김광수,조대수,김도현,최혜옥,Kim, Kwang-Soo,Cho, Dae-Soo,Kim, Do-Hyun,Choi, Hae-Ock 한국공간정보학회 2001 개방형지리정보시스템학회 논문지 = Journal of the Korea Open Geogr Vol.3 No.1
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.
개조된 GMA용접공정을 이용한 SiC/AI 복합재료의 제조 및 특성

개조한 가스 금속 아아크 용접공정을 이용하여 SiC/AI 금속기 복합재료를 제조하고 그 특성을 조사하였다. AI 모재위에 강화입자의 크기와 부피분율을 변화하여 다양한 SiC/AI 복합재료층을 제조하였고, 만들어진 복합재료층의 특성은 미세조직관찰과 미소경도시험을 통하여 이루어졌다. 복합재료층의 두께는 약 7-8mm로 측정되었고 균일한 강화입자의 분포도를 얻을 수 있었다. 분산입자의 부피분률은 Ar가스의 유량에 의하여 조절하였고 분산입자의 부피분률이 증가하고 크기가 작아짐에 따라 기지의 수지상 응고조직은 더욱 미세화되었다. 복합재료의 부피경도는 분산입자의 부피분률이 감소함에 따라 낮아졌으나 입자 크기에는 크게 변화가 없는 것으로 나타났다.

A fiberoptic sensor using a low-coherence SLD as a light source has been studied. The sensor system employing an intrinsic fiber Fabry-Peort interferometer as a sensing tip and a fiber Mach-Zehnder interferometer as a processing one, overcomes the ambiguous reading caused by the highly periodic natrue of conventional high-precision interferometric sensors and provides unambiguous identification of the desired phase among several candidates on the transfer function of an interferometric signal. A tentative application to the temperature sensor shows the potential that the fiberoptic sensor has a side-dynamic range of $0-900^{\circ}C$ as well as reasonable resolution higher than $0.1^{\circ}C$ without ambiguity. Due to the inherent property of the optical fiber itself and the intrinsic fiber Fabry-Perot interferometer, the proposed fiberoptic sensor will give obvious benefits when it is applied to harsh environments to monitor some physical parameters such as temperature, strain, pressure and vibration.

It was identified by the excavation that architecture remains were confirmed buddhist temple consist of ruins of main building of a temple, auditorium site, ruins of stone pagoda, embankment, pedestrian Facilities and drainage etc. in the Gwangmyeong-dong site. The site has been held temple arrangement with 1 main building of a temple, twin Pagodas from the Unified Silla period to Goryeo dynasty. The temple constructed after that was destroyed the architecture in the Unified Silla period. It seems that aristocrat or royalty power of within group of the nearby remains of city which was constructed in the Unified Silla period build and visit the temple. Considering there are excavations, it assumes that the temple had been constructed during the last days of the Unified Silla, was closed up during the mid-Goryeo Dynasty.

The increasing industrialization of the world has led to precipitous rise for the demand of petroleum-based fuels. The world is presently confronted with the twin crises of fossil fuel depletion and environmental pollution. The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in the present. Bioenergy is playing an increasingly important role as an alternative and renewable source of energy. Use of Bioenergy has several potential environmental advantages. The most important perhaps is reduction in life cycle greenhouse gases emissions relatives petroleum fuels, since bioenergy is derived from plants which convert Carbon dioxide ($CO_{2}$) into Carbohydrates in their growth. Bioenergy includes solid biomass, biomas and liquid bio-fuels which are fuels derived from crop plants, and include biomass that's directly burned. The two most important bio liquid fuels today are bioethanol from fermenting grain, grass, straw or wood, and biodiesel from plant seed oil.

생물정보학은 넓은 의미로 컴퓨터를 이용하여 모든 생화학정보를 광범위하게 연구.활용하는 학문이라고 할 수 있다. 하지만 최근의 인간유전체사업(Human Genome Project)의 인기에 의해 생물정보학이 DNA나 단백질의 서열 정보 분석의 분야로만 편중되어 의미되는 경향이 많은 것이 사실이다.
