서비스 지향 아키텍처는 기업 인프라의 복잡성 및 유지비용을 최소화 하고, 기업의 생산성과 유연성을 극대화할 것으로 기대되어 차세대 소프트웨어 아키텍처로 각광받고 있다. 이러한 서비스 지향 아키텍처 기반의 시스템이 효율적이고 성공적으로 자리 잡기 위해서는 올바른 서비스 식별과 구성이 필수적이다. 하지만 서비스를 식별하기 위한 요구사항 분석과정은 비즈니스 업무를 분석하는데 집중되어 있으며, 비기능 요구사항은 비가시적인(invisible) 특성으로 인해 쉽게 간과되어 설계에 반영되기 어렵다. 기존의 방법들은 이러한 비기능 요구사항을 객체수준에서 반영하기 때문에 서비스 조합으로 새로운 서비스를 창출하는 서비스 지향 아키텍처의 구조에서는 비기능 요구사항을 달성하기 어렵다. 본 논문은 서비스 패턴에 적용 가능한 비기능 요구사항을 식별하고 서비스 지향 아키텍처에 필요한 패턴을 분석한다. 그리고 식별된 비기능 요구사항을 달성하기 위한 서비스 패턴을 제안한다.

In this paper, a novel impact sensing device for an ESAF(Electronic Safe and Arming Fuze) is presented. An impact sensing device is mounted in front of a weapon, and it detects an impact when it crashes against a target. There are two main design requirements to enhance the firing functional reliability of the ESAF; an operational reliability and a reduced latency, which is a delay time needed for sensing the impact. The design method of the contact-type impact sensing device, which employs an FPCB(Flexible Printed Circuit Board) so it can be used other weapons, is proposed. The tests demonstrated that the design described in this work show a reduced delay time with ensuring the operational reliability.

A new logistics concept is needed through the sharing information between suppliers and consumers, which maximizes the customers service and its flexibility by changing functional- oriented to process-oriented. As in many other industries, communication and data manipulation technology have led to systematical change to the logistics industry. One of the biggest changes of the industry that lies ahead is Consolidated Transportation. To improve this systematically false logistical environment, developing an integrated logistics information system with consolidated transportation, framework, standardization, and data integration is essential. However, no party outstands as the leading party for nationwide improvement of logistics, nor does the right analysis and design for it. Therefore, successful nationwide logistics model is yet to exist. This paper provides individual parties, which consider efficient consolidated transportation as their business models, with instructions for logistics information system so that they could be competitive in the market. It also helps companies collect user requirements for efficient consolidated transportation, and utilize it for its development. Finally, this paper extracts the design of algorithm for the efficient consolidated transportation.

This paper proposes a design method for improving the disassembly by using the axiomatic approach. A product developer must design disassembly as well as assembly when designing the structure of a product. Axiomatic approach is a design tool that optimizes design. In this paper design evaluation method using information axiom sets impact variables and value function. As a result, examining the relationship between the functional requirements and evaluating the information can optimize designs.

Recently, it is getting more and more important ensuring the integrity for the equipment degradation according to the increase of nuclear power plant operating period. In many equipment of the nuclear power plant, snubbers mainly installed in reactor coolant pumps, steam generators and piping protected the equipment and piping from the occurrence of transient dynamic loads such as the earthquake, thermal load during the plant operation. This report describes the function, regulation, inspection requirements and management status of the snubbers installed in domestic nuclear power plants.

It is expected that the need of a social welfare hall gradually arise in our community, since we regard the meaning of social welfare as a right which all of the people should have as guardians of the weakest members. Today, ambiguous guidelines on architectural plan of the social welfare hall, which are still not suitable for function and role of this hall, and are not corresponded with architectural design from the early design phase, are proposed in our design competition, because these kinds of halls have not been often built according to functional requirements of the social welfare. Therefore, this study proposes an architectural strategy that should be considered before designing a new social welfare hall, through an analysis of spatial usage in operation programs of various newly-built halls in Korea.

데이터세트 기록은 단순한 이관모듈의 작성이나 API를 제공하는 것만으로는 효과적이고 효율적으로 이관을 수행하기 어렵다. 데이터세트의 기록은 기록 건의 범위가 명확하지 않으며, 이관되는 과정에서 데이터의 보정과 품질개선이 필요하며, 메타데이터의 적극적인 수집보완이 요구되는 등 규격화된 전자문서 중심의 기록과는 이관 과정의 특성이 다르기 때문이다. 따라서 데이터세트 기록의 이관 시에는 세부적인 이관 절차를 따라 이관대상 데이터의 상태를 확인하고 필요한 조치를 취해나갈 수 있도록 지원해주는 이관도구가 필수적이다. 이관의 이관 작업과 달리 이관 작업을 지원하는 도구가 필수적이다. 이 논문에서는 행정정보시스템에서 데이터세트 기록을 추출하여 아카이브 시스템으로 이관하는 과정을 지원하는 도구가 갖춰야 할에 기능요건을 제시하고자 한다.

We present a design study for a remote sensing camera system which can be operated in multi-channel mode simultaneously with several bandpass filters. The camera control electronics is based on the multiplexed driving concept, which can provide a variety of flexibility for system control parameters and its individual optimisation. The design can also be applied to any system with linear sensors or frame sensors according to its functional requirements. The system design parameters have been examined, including modification of driving waveforms for different types of sensors, waveforms for low-nosie readout circuit in analog chain, and synchronisation with other signal processing.

Since software development team members have been more geographically spread due to the globalization of business and Internet technologies, the management of deliverables and communication efforts for developing high-quality software products on time is becoming more complicated. Among the functional requirements for collaborative software development management, the manipulation of shared information objects is essential for the collaborative work among distributed development team members. This paper proposes an integrated information object management framework comprised of a so-called BOC (Bill Of Class) scheme and a standardized software part dictionary for managing shared information objects efficiently among distributed co-workers. In order to manage these complex information objects, the proposed framework adopt product structures represented by Bills Of Materials (BOM) as stems for integrating the various information objects. Based on the proposed framework, a collaborative software development management system (CSDMS) is implemented, and the functionalities and the structure of the system are also described in this paper. The proposed system provides sufficient functionalities for the change management of information objects and the management of their relationship to other objects rather than existing system.

Urban railway signaling system is for train operation with safety in the urban crowded area, that has been increasing the demand of use of advanced train control systems with safe. European Commission is supporting the UGTMS(Urban Guided Transport Management System) project for the research and development. The main objective of UGTMS is to provide the European urban guided transport sector (comprising metro, tram and light rail systems) with a common Management System. A key topic is the extent to which the specifications for the successful ERTMS(European Rail Transport Management System) can be adapted to UGTMS needs. Beyond this, it is necessary to define the relevant functional and system requirements for all types of urban guided transport management systems in order to improve interoperability and intermodality. Also to be explored are the prospects for open system standards. In this article, we look into the trend of the standardization through the UGTMS project in Europe and consider any benefit to the project of the standardization for the urban railway signaling system in Korea.
