For the excellent U web services, the program developers should create both user's client program and the sewer program Recently, the structural alteration of programs are often caused by infernal and external environment concerned with social trends and preferences as well as user's requirements expectations. So, for reducing the development time and workload of XML web service programs, it is necessary to develop the web program generation tools. This paper suggest how to design and implement the web-based XML Tree builder, which was able to provide the information for promptly and easily generating the XML Schema, XML Stylesheet and XML Document through the XML Development Supporting Server System.

The IHO S-100 is a standard on the universal hydorgraphic data model for supporting information services that integrate various data in maritime and provide proper information for safety of vessels. The S-100 is used to develop S-10x product specifications which are standards on guideline for creation and delivery of specific data set in maritime. The product specification for feature-based data such as ENC(Electronic Navigational Chart) data includes a feature catalogue that describes characteristics of features in that feature-based data. The feature catalogue is developed by domain experts with knowledge on data of the target domain. However, it is not feasible to develop a feature catalogue according to the XML schema by manual. In the IHO TSMAD committee meeting, needs of developing technology on building feature catalogue has been discussed. Therefore, we present a feature catalogue builder that is a GUI(Graphic User Interface) system supporting domain experts to build feature catalogues in XML. The feature catalogue builder is developed to connect with the FCD(Feature Concept Dictionary) register in the IHO(International Hydrographic Organization) GI(Geographic Information) registry. Also, it supports domain experts to select proper feature items based on the relationships between register items.

Geospatial information for river network and watershed boundary have played a fundamental roles in terms of river management, planning and design, hydrological and hydraulic analysis. Irrespective of their importance, the lack of punctual update and improper maintenance in currently available river-related geospatial information systems has revealed inconsistency issues between individual systems and spatial inaccuracy with regard to reflecting dynamically transferring riverine geography. Given that digital elevation models (DEMs) of high spatial resolution enabling to reproduce precise river network are only available adjacent to national rivers, DEMs with poor spatial resolution lead to generate unreliable river network information and thereby reduce their extensible applicabilities. This study first of all evaluated published spatial information available in Korea with respect to their spatial accuracy and consistency, and also provides a methodology and tool to modify existing low resolution of DEMs by means of striation of conventional or digitized river network to replicate input river network in various degree of further delineation. The tool named FSND was designed to be operated in ArcGIS ModelBuilder which ensures to automatically simulate river network striation to DEMs and delineation with different flow accumulation threshold. The FNSD was successfully validated in Seom River basin to identify its replication of given river network manually digitized based on recent aerial photograph in conjunction with a DEM with 30 meter spatial resolution. With the derived accuracy of reproducibility, substantiation of a various order of river network and watershed boundary from the striated DEM posed tangible possibility for highly extending DEMs with low resolution to be capable of producing reliable riverine spatial information subsequently.

웹 애플리케이션에서 요구되고 있는 필요 기술이 증가함에 따라 이들 기술 사이에 상호작용이 많아지고 복잡도가 증가하여 웹 애플리케이션을 개발하고 효율적으로 사용하기가 점차로 더 어려워지고 있다. 이에 본 연구는 웹 애플리케이션의 기본적인 요구사항을 재검증하여 복잡도를 감소시키고, 폼 기반 웹 애플리케이션 모델을 생성할 수 있는 MVC 기반 웹 애플리케이션 빌더를 정의하고자 한다. 이 툴은 클라이언트와 서버 사이의 입 출력 데이터 변환에 필요한 코드를 자동으로 생성해 주고, 클라이언트와 서버 간의 데이터 교환을 감소시켜 복잡도를 줄일 수 있도록 해준다.

The railway signaling system consists of computerized vital devices. Therefor it is important to validate the required functions of developed signaling system. To verify the condition and functions of signaling functions, the plentiful laboratory test is required. To achieve this, the emulation S/W for signaling test-bench is needed. The object-oriented concept for trackside signaling equipments emulation is described in this paper.

This study is to find out the major design variables of Green roof system effecting on the building energy consumption. Therefore, in three categories of green roof system, namely, foliage layer, soil layer and irrigation, 10 design variables are selected and simulated with one-story case building. Simulation is carried out with Design Builder and EnergyPlus. Finally, it was found out the effects of major variables affecting on the building heating and cooling energy and how they are affecting on the heating and cooling seasons respectively.

This study identifies the current status of hanok design process and required design information through individual survey and interview with hanok architects and builders to suggest a proposal. Current design system turns out to be a common design process not reflecting hanok's unique mechanism of production. The proposal consists of the alternative design process, 'Initial survey / Site and structural planning / Spatial layout and form / Openings, interior and exterior elements design / Detail design', containing the specialty of hanok's mechanism, and the lists of design information required in its each stage. The proposed design process also emphasizes the significance of consultation in a way of designing coordination, and classifies the specific contents for each consultation moments. The study is expected to contribute for architects including the group who are not specialized in hanok to improve the architectural quality by following the systematic design process. Also the design system provides a framework to organize the vast range of design information being recently developed in the technique-oriented area.

In tills paper, we design it decoder for the FLEX high speed paging protocol. The decoder that we design consists of a synchronizer, a de-interleaver, a error corrector and a packet builder In the FLEX protocol, a word is coded using HCH algorithm. In this design, we do not use a look-up table in order to decrease a chip area of the BCH decoder. The simulation result shows that the decoder is correctly designed
