  • The Virtual Interface Architecture (VIA) is usually suggested as a new standard high-performance communication of the cluster systems. However the VIA specification aims for platform independence, the current Intel VI Provider Library (VIPL) design favors systems with Intel architecture processors running the Windows operating system (OS). This paper aims for clarifying the guesstion problem of VIA and VIPL in the newtrul time of CPU Architecture and OS further more, It suggests the solution aiming the communication in the other CPU or OS

  • This appendix deals with the Korean air interface standard, TTA-62, for CDMA Mobile Systems, (CMS) [1]-[2]. The standard has been set up by Telecommunications Technology Association (TTA) which is a standardization organization in Korea [3]. This standard is an important specification that should be determined prior to the development of a digital cellular system. The CMS has been developed on the basis of this standard and the papers published in this special issue are the results of the CMS development. This appendix also describes the technical commonality of these papers. It covers the outline of the air interface and protocol specifications. The outline includes its major characteristics, radio protocol architecture, functionalties, and call processing. A comparison is also given between TTA-62 and IS-95[4], a North American digital cellular standard.

  • 기업간 전자상거래를 위한 국제표준인 ebXML 은 ebBPSS(ebXML Business Process Specification Schema)와 CPA(Collaboration Protocol Profile)에 기반하여 거래 당사자들이 협업 형태의 업무 처리 절차에 따라 문서 및 데이터를 주고 받을 수 있도록 해 준다. 거래 당사자들의 내부 업무처리 시스템에 연동되어 B2B 업무를 처리할 수 있도록 해주는 시스템을 BSI(Business Service Interface)라 하며, 이는 트랜잭션 관리, 업무 프로세스의 코레오그래피(Choreography), 문서 관리, 보안 관리 등 협업과 관련된 대부분의 역할을 수행하게 된다. 기업간 협업에 있어 가장 중요한 사항 중 하나는 어떤 상황에서도 양쪽의 협업상태 정보는 일관성을 유지해야 한다는 것이다. 이는 거래의 신뢰도를 확보하기 위한 필수사항이라 할 수 있다. 본 논문에서는 ebXML 프로토콜에 따라 거래행위시 협업상태 정보가 양측 거래파트너에서 각기 다르게 나타날 수 있는 상황을 살펴 보고 이에 따른 BSI 시스템의 대처방안에 대해 살펴보고자 한다.

  • Recently, the necessity of rapid response to social problems such as disasters and quarantine arising from the complex and diverse social structures has emerged. As the number of large buildings increases, large-scale human damage is expected in the event of a disaster such as fire. To solve this problem, efficient control must be achieved through interfacing with various equipment and facilities installed inside the building. In this paper, we intend to study the interface method for various facilities in the building for efficient control. In detail, the facility standard model is defined by examining the status and specification of building. In addition, we intend to design and propose a standard facility communication data frame to support the protocol applicable to this model.

  • For the record management of administrative information datasets in Korea, it is recommended to utilize SIARD as a transfer specification when transferring administrative information datasets. However, there are many cases where the application of SIARD is not suitable due to the record management unit of administrative information datasets, technical limitations of tools that support SIARD, and the realistic situation of public institutions. In this study, we propose a plan to diversify the transfer specifications of administrative information datasets other than SIARD. In the record management of administrative information datasets, the need to reproduce the user interface associated with the dataset has been discussed but not specifically presented. This study confirms that the user interface is a property to be preserved from the perspective of Significant Properties, proposes a method to effectively reproduce the user interface, and provides an example of actual verification.

  • A TCS(Train Control System) is the core facility to ensure the safety and efficiency of train operations, it is difficult to have interoperability between the TCS suppliers. To ensure the interoperability between TCSs, there is a need for definition, validation and standardization on the system configuration, the functions of subsystems, the interface between subsystems an the system protocol. In this paper, we analyzed the completeness of the KRTCS(Korean Radio based Train Control System) specification, derived supplements what you need to apply the KRTCS specification to new urban lines.

  • In electronic commerce, a registry is an integrated software system that supports access to registry metadata in order to locate and retrieve registered objects it can be discovered and used by a client or customer. In general, a registry consists of information model and its service. A registry implementation supports a registry services interface that can be used by abstract agents to assist a human or some other software process to register new objects, provide appropriate metadata for those objects, browse or query registry content, filter out irrelevant references, and retrieve the content of selected items. We show a layered registry architecture that is flexible enough to support the required specialization of many different kinds of registry specification of other sponsoring groups. This architecture could easily adopt different registry specification. This paper suggests a prototype implementation model which supports ebXML Registry standard based on this layered architecture.

  • Driven by the explosive expansion and acceptance of the Internet and its multimedia front-end, the Web, a new generation of the modeling and simulation tools have come up with the name of Web-Based Simulation (WBS). Most of WBS libraries inherit its powerful advantages from Java. However, there are cases where explicit specification of models or interface objects is more desirable than the black-box programs. This paper presents an XML-based DEVS (Discrete Event System Specification) markup language for sharing simulation models on the Web. DEVS provides a system-theoretic formalism for the language while XML supports platform-independent data access. This paper focuses on the design of such a language.

  • Hybrid robust image processing algorithm to extract visual features of melon during the cultivation was developed based on a wireless tele-operative interface. Features of a melon such as size and shape including position were crucial to successful task automation and future development of cultivation data base. An algorithm was developed based on the concept of hybrid decision-making which shares a task between the computer and the operator utilizing man-computer interactive interface. A hybrid decision-making system was composed of three modules such as wireless image transmission, task specification and identification, and man-computer interface modules. Computing burden and the instability of the image processing results caused by the variation of illumination and the complexity of the environment caused by the irregular stem and shapes of leaves and shades were overcome using the proposed algorithm. With utilizing operator's teaching via LCD touch screen of the display monitor, the complexity and instability of the melon identification process has been avoided. Hough transform was modified for the image obtained from the locally specified window to extract the geometric shape and position of the melon. It took less than 200 milliseconds processing time.

  • This paper presents an implementation method of Profibus interface software using FMS(Fieldbus Message Specification). The Profibus interface software is implemented on PC which is widely used as an industrial computer as well as a commercial embedded controller called IUC(Intelligent Universal Controller). In order to enable the Profibus interface software to handle many application tasks and communication services, two kinds of real-time/multi-tasking operating system, OS-9 and CTask, are utilized. We also develop an experimental model of Profibus-based automation system, and evaluate the performance of the Profibus network. Through experiments, the user layer level message latency is measured with respect to the change of message length, message generation interval and TRT(Target Rotation Time). The results of experiment are compared with those of a simulation model which comprises only the physical and data link layers of Profibus. The results of this study shows that the message latency in the user layer level occupies fairly a large part of the total message latency.
