The railway signaling system consists of several vital computerized equipments. Now the project for development of signaling system for the next-generation high-speed train is progressed according to the consortium. The developing signaling system by this project, kTCS(Korean Train Control System), is composed of kTCS-CTC, kTCS-IXL, kTCS-ATC and etc. The KTCS signaling has to be operated as a integrated system by interface between each signaling. To achieve these, communication protocols between each signaling have to be designed and message codes are defined. In this paper the configuration of integrated kTCS system and designed communication protocol is presented.

An integrated program of driving simulator has been developed for excavators using the Motif, OpenGL, and C compiler. The developed program not only offers a GUI but also covers graphic algorithms, therefore, the user can easily run the driving simulator whose components include a simplified visual graphics system. Several graphics technique are combined and applied to the simulator program in order to increase the speed of graphical representation, which access computer memories, mix 2D models with 3D ones, and use the basic position detection method. A text format environment file has been utilized for organizing more flexible driving circumstances.

FEM numerical models have been known to provide an extensive applicability to the field of water resources development. However, some of restrictions such as requiring considerable number of input data and numerous subprocess were the problem of using such FEM numerical models. Especially, where the model is applied to the complex coastal area, difficulties will be intensified. Therefore it is necessary that the profitable user interface, data optimization, and structured system should be developed if the models could be used effectively. In this study, it is intended that development of integrated system for simulations of FEM numerical models to give better applicability in the field of water resources development. By using integrated system which was developed in this study, it would be concluded that the efforts to need some treatments for subprocesses of the FEM numerical model were decreased and GUI environment proved to be convinient for use for the on-the-job users.

전체 연속간행물 가운데 전자저널이 차지하고 있는 비중은 급속히 증가하고 있는 반면 이용자편이형 전자저널 인터페이스 구축은 상대적으로 소홀하다. 이 연구는 국내 대학도서관의 전자저널 관리와 인터페이스 실태 조사를 바탕으로 한 통합인터페이스 구축에 관한 것이다. 연구를 수행한 결과 여러 통합인터페이스 유형 중 자관의 인쇄형 연속간행물도 함께 검색할 수 있고 전자저널 원문에도 바로 접근할 수 있는 통합목록 방식을 채택하는 것이 가장 바람직하며 이의 구현이 시급한 것으로 나타났다.

An integrated design system has as its aim the incoporation of all the design processes, such as, planning, preliminary design, analysis, detailed design (mamber design), evaluation, and drafting into an unified software system. Successful implementation such a system could lead to major improvements in efficiency by eliminating duplication of data and efforts. reducing errors, saving design time, providing management support, and so on. This study presents a methodology for an computer-integrated design system for building structures, synthesizing algorithmic procedures and knowledge based expert systems on the network database. Network database, which was designed to store all information systematically during the design processes, provides centeral communication area between algorithms and expert systems. The conventional procedural codes automate the routine design phases such as structural analysis, whereas knowledge-based expert systems support designer's decisions at the creative design phases such as preliminary design etc. The user interface with interactive and batch modes controls the design phases and manages design information and activates the algorithms and the expert systems. The concept presented in this paper will contribute to the formulation of automated design systems for building structures.

DNA microarray is a high-throughput biomedical technology that monitors gene expression for thousands of genes in parallel. The abundance and complexity of the gene expression data have given rise to a requirement for their systematic management and analysis to support many laboratories performing microarray research. On these demands, we developed Xperanto for integrated data management and analysis using user-friendly web-based interface. Xperanto provides an integrated environment for management and analysis by linking the computational tools and rich sources of biological annotation. With the growing needs of data sharing, it is designed to be compliant to MGED (Microarray Gene Expression Data) standards for microarray data annotation and exchange. Xperanto enables a fast and efficient management of vast amounts of data, and serves as a communication channel among multiple researchers within an emerging interdisciplinary field.

The governing equations for high-speed lateral atomizing injector nozzle flow based on the LES-VOF model in conjunction with the CSF model are presented, and then an integrated parallel computation are performed to clarify the detailed atomization process of a high speed nozzle flow and to acquire data which is difficult to confirm by experiment such as atomization length, liquid core shapes, droplets size distributions, spray angle and droplets velocity profiles. According to the present analysis, it is found that the atomization rate and the droplets-gas two-phase flow characteristics are controlled by the turbulence perturbation upstream of the injector nozzle, hydrodynamic instabilities at the gas-liquid interface, shear stresses between liquid core and periphery of the jet. Furthermore, stable and a high-resolution computation can be attained in the high density ratio (pl/ pg = 554) conditions conditions by using our numerical method.

Nowadays, the modeling of information systems have been enabled by various models and methodologies that are used for different purposes and perspectives upon the systems. The integrated modeling methodology that integrates these models and methodologies has become important concerns in system integration such as CIM and PDM. The primary objective of this paper is to propose a comprehensive integrated modeling methodology that integrates the OOIDEFO function model, OOIDEFO information model, node model, user interface model, and organization model for an effective analysis, design and implementation for system integration. This methodology covers the generic requirements of modeling methodology such as graphical notations, modeling processes, and abstraction mechanisms. Also, this methodology uses an 00 paradigm throughout the entire systems development life cycle. In order to prove the consistency and efficiency of the proposed methodology, the CIMS for ship production is modeled and prototyped.

This study analyzed the offshore plant industry and related regulations such as ISO, IEC, and Norsok Standards to develop an integrated network management system (INMS) capable of both on-site and remote management and configuration of IP-based network equipment in offshore plants. The INMS was designed based on actual specifications and POS plans, and a plan of management was verified through an offshore plant engineering company. Various modules such as PAGA interface modules, CCTV, IP-PBX, and HF-radio communication modules were developed for system implementation. Protocol and data design and screen design were followed by framework development and introduction of the automatic satellite communication function.
