Component based design is perceived as a key technology for developing advanced real-time systems in a both cost- and time effective manner. Already today, component based design is seen to increase software productivity, by reducing the amount of effort needed to update and maintain systems, by packaging solutions for re-use, and easing distribution. Nowdays, a thousand and one companies in If(Information Technology) industry such as Sl(System Integration) and software development companies, regardless of scale of their projects, has spent their time and endeavor on developing reusable business logic. The component software is the outcome of software developers effort on overcoming this problem; the component software is the way propositioned for quick and easy implementation of software. In addition, there has been lots of investment on researching and developing the software development methodology and leading If companies has released new standard technologies to help with component development. For instance, COM(Component Object Model) and DCOM(Distribute COM) technology of Microsoft and EJB(Enterprise Java Beans) technology of Sun Microsystems has turned up. Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, It suggest that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. about implements and accomplishes the modeling for the Product Control component development by applying CCD(Contract-Collaboration Diagram), one of component development methodology, to MRP(Material Requirement Planning) System

안드로이드 어플리케이션은 인텐트를 이용하여 다른 어플리케이션의 컴포넌트를 호출하여 실행시킬 수 있다. 하지만 컴포넌트들 사이의 상호작용이 정상적으로 처리되지 않으면 잘못된 컴포넌트가 실행되거나 전화 수신과 같은 시스템 브로드캐스트를 처리하지 못하는 문제점이 발생할 수 있다. 본 논문에서는 이와 같은 상호작용 문제점을 검사하기 위해 서로 연동하여 동작하는 어플리케이션들로부터 컴포넌트 기반의 다이어그램들을 생성하고 이를 하나의 병합된 다이어그램으로 변환하여 테스트 시나리오를 생성하는 방법을 제안한다. 제안된 방식은 기존의 테스팅 기법에서 고려하지 못한 어플리케이션간의 상호작용 검사를 효율적으로 수행할 수 있다.

With a purpose of finding out the effects of cattle slurry applicatioin on the dry matter yield, yield component, and botanical composition in the mixed sward, a field experiment was conducted with two times and five levels of cattle slurry application. The experimental field was laid.out in a split-plot design with three replications, and lasted from September. 1986 to October, 1990 at the Livestock Experiment Station in Suweon, The results obtained are summarized as follows: 1. At each harvest time, the plant growth of the plots with cattle slurry application was slightly worse when compared to dressing of mineral fertilizer. 2. Average dry matter yield for 4 years was not significantly different between the slurry application times, just after cutting, and 15 days after cutting, The DM yield in the plot with cattle slurry 30 m!/ha and mineral fertilizer(9,095 kg/ha) and with cattle slurry 60 m1/ha and mineral fertilizer(8, 987 kg/ha) were decreased by 8% and 10% than that of the plot with mineral fertilizer application(9,937 kg/ha), respectively. 3. The DM yield component of the plots with cattle slurry application just after cutting was much better when compared to manuring 15 days after cutting. And it was much better in the plot with cattle slurry 60 m"/ha and mineral fertilizer which was composed of 73.8% grasses(6.636 kg/ha). 24.6% legumes (2,207 kdha) and 1.6% weeds(144 kdha). 4. In general, the botanical composition was relatively good in the plots with slurry application just after cutting. Grassland vegetation of the plots with cattle slurry 60 m"/ha and mineral fertilizer was changed into much better botanical composition with 66.8% grasses, 30.2% legumes and 3. 1% weeds at the end of the experiment.xperiment.

We apply independent component analysis (ICA) for extracting an optimal basis to the problem of finding efficient features for representing speech signals of a given speaker The speech segments are assumed to be generated by a linear combination of the basis functions, thus the distribution of speech segments of a speaker is modeled by adapting the basis functions so that each source component is statistically independent. The learned basis functions are oriented and localized in both space and frequency, bearing a resemblance to Gabor wavelets. These features are speaker dependent characteristics and to assess their efficiency we performed speaker identification experiments and compared our results with the conventional Fourier-basis. Our results show that the proposed method is more efficient than the conventional Fourier-based features in that they can obtain a higher speaker identification rate.

This paper described some applications using Open GIS Component that was called MapBase. There were 4 applications : KSDI(Korea Spatial Data Infrastructure) funded by MOIC(Ministry of Information and Communication), National Plants Resource Management System supported by Korea Forest Service, 7-Underground Facilities Management System of Cheongju funded by MOCT(Ministry of Construction and Transportation), and National Disaster Management System supported by MOGAHA(Ministry of Government Administration and Home Affairs. Because they wanted to access heterogeneous spatial database, it was necessary to select MapBase as their base methodology. The main feature of MapBase was component S/W which provided the interoperability and reusability among GIS applications as well as non-GIS information system through common specification. In this paper, we showed some applications' architectures and functions to increase understanding MapBase. That would help you to make application using MapBase.
