The importance of software is getting high in development of the digital device (digital camcoder, digital camera, mp3 player, ....). And because the sire of software becomes larger and complicated, the necessity of software configuration management (to solves a software crisis) is increased. The general software configuration management system shows lack of the property and features of software development environment for image processing algorithm due to its wide range to be covered. Image processing algorithm development environment has properties like repetitive analysis and simulation using visual programming environment where, beside support of elementary development functions. component(or library) can be combined and tested interactively. Moreover, the method to look fast and effectively for component having similar function is required. In this paper, we present the system which supports the software configuration management method for a simulation tool and the property in the visual programming environment. And we relate our system to real simulation tool so as to check its ability as the software configuration management system for image processing algorithm development environment.

A dynamic mathematical model of a thermal power plant with a single drum-type boiler is described with the base on modular concept. The present process model, which is including full scope of the components and high load changes, is based on physical approach through lumped parameters. The module, which means a component of the power plant and must essentially depict the characteristics of the component well, might be interconnected using pressure nodal method in a arrangement determined by users. With the results of the load changes of 75 MW to 95 MW and 95MW to 75 MW with the rate of 3 MW/min, the applicability of the process model is examined connecting to DCS(Dispersion Control System), which has a real running logic of 100 MW real power plant.

In this study, we cultivated 115 Soritae and 86 Yakkong black soybean landraces collected from ten different locations in Korea. Then, the variations of three yield components (one-hundred seeds weight (HSW), number of seeds per pod (SPP), and yield per plant (YPP)) and three anthocyanins (cyanidin-3-O-glucoside (C-3-O-G), delphinidin-3-O-glucoside (D-3-O-G) and petunidin-3-O-glucoside (Pt-3-O-G)) were investigated according to landrace type and collection area. Both yield components and anthocyanin contents significantly varied between the soybeans demonstrating genetic differences. Soritae landraces had the highest average HSW and TAC, whereas Yakkong landraces displayed the highest average SPP irrespective of collection area. Relatively, Yakkong landraces from Gyeongsangnam-do (1697.29 mg/100 g) and Soritae landraces from Gyeonggi-do (2340.94 mg/100 g) had the highest average TAC. Principal component analysis clearly separated Soritae and Yakkong landraces. Moreover, TAC and C-3-O-G showed positive and significant associations in both Soritae (r = 0.972) and Yakkong (r = 0.885) landraces, while yield components showed negative or weak correlations with each other. Overall, ten landraces were identified as important resources owing to their high yield (>150 g/plant) and high level of TAC (>2300 mg/100g). This study could lay foundations to molecular level investigations and reinforce the use of Yakkong and Soritae landraces during cultivar development.

Recently, the new software paradigm in information technology (IT) is the component-based development (CBD) technology that has brought as a result of the distributed computing environment (DCE). The CBD has reduced a program developing time and has been designed to make a distributed computing environment easier in the Internet and Intranet environments. These changes of software technology have influence on the geographic information system (GIS) and the CBD technology is highly needed as a point of view of the technique and policy of the geographic information system. In this paper, we designed and implemented an Enterprise Server for the efficient development and management of GIS components. Especially, the Enterprise Server was developed with the Enterprise JavaBeans Specification 1.1 that had been proposed as an industry standard by the Sun Microsystems. The Enterprise Server can allows users to manage the Unified Modeling Language (UML) and Design Patterns for the development of GIS components, develop a GIS component container which obeyed the Open Geodata Interoperability Specification (OpenGlS), manage spatial metadata through a spatial XML (eXtensible Markup Language) engine, and implement a TESTBED server for testing and verification of developed GIS components.
