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.

Development of digital main control rooms (MCRs) has greatly changed operating environments by altering operator tasks, and thus the unique characteristics of digital MCRs should be considered in terms of human reliability analysis. Digital MCR tasks can be divided into primary tasks that directly supply control input to the plant equipment, and secondary tasks that include interface management conducted via soft controls (SCs). Operator performance regarding these secondary tasks must be evaluated since such tasks did not exist in previous analog systems. In this paper, we analyzed SC-related tasks based on simulation data, and classified the error modes of the SCs following analysis of all operational tasks. Then, we defined the factors to be considered in human reliability analysis methods regarding the SCs; such factors are mainly related to interface management and computerized operator support systems. As these support systems function to reduce the number of secondary tasks required for SC, we conducted an assessment to evaluate the efficiency of one such support system. The results of this study may facilitate the development of training programs as well as help to optimize interface design to better reflect the interface management task characteristics of digitalized MCRs.

For the strategic management of the small and/or mid sized clinics, the introduction of the clinic information system is necessary. Currently there are not many information systems for the clinics, yet. In this study, we have developed a clinic information system (CLINSYS) as a guiding prototype and suggested the development directions of the total integrated clinic decision support system. For the better user interface and easy communication. the object-oriented language Macintosh Hyper-Card and Excel are used as the developing tools. And as a part of the integrated decision system, an expert system to consult about the urine test and the blood test interpretation has been developed using the Macintosh spreadsheet Excel.

As digital and computer technologies have grown, human-machine interfaces (HMIs) have evolved. In safety-critical systems, especially in nuclear power plants (NPPs), HMIs are important for reducing operational costs, the number of necessary operators, and the probability of accident occurrence. Efforts have been made to improve main control room (MCR) interface design and to develop automated or decision support systems to ensure convenient operation and maintenance. In this paper, an integrated decision support system to aid operator cognitive processes is proposed for advanced MCRs of future NPPs. This work suggests the design concept of a decision support system which accounts for an operator's cognitive processes. The proposed system supports not only a particular task, but also the entire operation process based on a human cognitive process model. In this paper, the operator's operation processes are analyzed according to a human cognitive process model and appropriate support systems that support each cognitive process activity are suggested.

In this study, an integrated GMS(Geostationary Meteorological Satellite) receiving ground system, which includes the real-time reception and image processing of WEFAX data, has been developed. The demodulator, PC demodulator, PC interface and application softwares of the system were made and integrated with the commercially available antenna and receiver. Hardwars of the system were described in this part. This system operates at IBM PC/AT or above. It can be used for students at school and for application research in the fields of meteorology, oceanography, hydrology and astronomy.

Purpose: The objective of this study is to develop a data middleware for u-IT convergence in agricultural environment monitoring, which can support non-standard data interfaces and solve the compatibility problems of heterogenous sensor networks. Methods: Six factors with three different interfaces were chosen as target data among the environmental monitoring factors for crop cultivation. PostgresSQL and PostGIS were used for database and the data middleware was implemented by Python programming language. Based on hierarchical model design and key-value type table design, the data middleware was developed. For evaluation, 2,000 records of each data access interface were prepared. Results: Their execution times of File I/O interface, SQL interface and HTTP interface were 0.00951 s/record, 0.01967 s/record and 0.0401 s/record respectively. And there was no data loss. Conclusions: The data middleware integrated three heterogenous sensor networks with different data access interfaces.

The aircraft manufacturers are constantly driving to reduce manufacturing lead times and cost at the same time as the product complexity increases and technology continues to change. Integrated Modular Avionics (IMA) is a solution that allows the aviation industry to manage their avionics complexity. IMA defines an integrated system architecture that preserves the fault containment and 'separation of concerns' properties of the federated architectures. In software side, the air transport industry has developed ARINC 653 specification as a standardized Real Time Operating System (RTOS) interface definition for IMA. It allows hosting multiple applications of different software levels on the same hardware in the context of IMA architecture. This paper describes a study that provided the avionics software design for separation of fault and backup of core function to reduce workload of pilot with cost efficiency.

최근 공개 표준과 통합 네트워크에 대한 요구가 증가하며, 하위 제어 계층에서도 이더넷 네트워크를 기반으로 한 시스템의 도입이 증가하고 있다. TCP/IP 기반의 네트워크를 상위 계층에서 하위 제어 계층까지 사용하는 방식으로 확장함으로써 공장 자동화용 애플리케이션을 이더넷 상에서 구현, 상위 관리 프로그램 및 DB 시스템과 직접 연동되는 통합 망 개념의 공장 자동화 시스템을 완성할 수 있게 된다. 본 논문에서 구현된 시스템은 공장 자동화 전용 이더넷 제어 시스템의 국제 표준인 Ethernet/IP 표준 시스템을 기반으로 하는 제어용 통신 디바이스를 구현하는 것을 목표로 하였다. 본 논문에서 구현된 시스템은 CIP의 표준 인터페이스에 기반한 네트워킹 기능을 수행하며, 이더넷 네트워크 환경이 다른 제어 시스템의 규격에 비하여 큰 대역폭을 갖고 있는 시스템이므로 네트워크의 데이터 전송 특성을 상당히 개선됨을 실험을 통하여 확인하였다.
