엔터프라이즈 환경의 시스템은 다양한 시스템을 활용하여 업무를 처리하고, 인터페이스 시스템을 이용하여 메시지를 교환한다. 인터페이스 통신 기반의 환경에서는 업무 복잡도가 증가할수록 많은 시스템과 인터페이스 시스템이 연계한다. 시스템 연계도가 증가할수록 개발 투입 인력이 증가하며, 이에따라, 정보 불일치 발생, 표준 미 준수 등 다양한 개발위험이 발생한다. 본 제안은 이러한 문제를 해결하기 위해 메시지 기반의 인터페이스 시스템의 정보를 집중, 관리하는 시스템을 제안한다. 시스템을 통해 인터페이스 시스템의 정보 통합 관리, 메시지 정보 배포, 표준 코드를 생성, 위험 관리 및 회피 방법을 제안한다. 제안된 시스템을 통해 개발환경의 정보 불일치 방지, 위험의 분석 및 회피, 자동 정보 배포 및 코드 생성이 가능하며, 궁극적으로 개발환경의 효율성 및 위험을 회피 할 수 있다.

기존의 상업용 데이타베이스 시스템들은 복잡한 오브젝트 들의 계층 구조에 의존하며 방대한 양의 데이타를 반복적으로 접근하는 CAD 데이타의 특성을 효과적으로 지원하지 못하여 CAD 데이타베이스의 중요성과 이의 효율적인 관리를 위한 연구의 필요성이 대두되었다. 본 논문에서는 CAD 데이타베이스의 효율적인 관리와 설계 도구들의 통합을 위한 좋은 환경을제공하기 위하여, 계층적 인터페이스 시스템을 설계하고 이의 구현을 위해 CAD 데이타베이스의 특성을 고려한 GROCO 모델을 제시하고자 한다. 배치기와 변환기의 두 개의 서브시스템으로 구성된 계층적 인터페이스 시스템은 CAD 데이타의 효율적인 관리를 위한 빠른 실용화를 위해 기존의 상업용 데이타베이스 관리 시스템과 CAD 도구들을 인터페이스 시키는시스템으로 개발되어 실제 CAD 도구들에 적용하고자 한다. GROCO 모델은 데이타의 의미들을 나타내기 위한 5개의 노드 타입들이 연결되어 방향 주기 그래프를 구성하고 있다. 이 모델은 이질적인 데이타들의 다양한 형태의 모임으로 구성된 복잡한 오브젝트들의 계층구조에 의해 이루어진 CAD 데이타의 특성을 효과적으로 지원하고자 한다.

The increasing of power and processing speed and miniaturization of central processor unit (CPU) used in electronics equipment requires better performing thermal management systems. A typical thermal management package consists of thermal interfaces, heat dissipaters, and external cooling systems. There have been a number of experimental techniques and procedures for estimating thermal conductivity of thin, compressible thermal interface material (TIM). The TIM performance is affected by many factors and thus TIM should be evaluated under specified application conditions. In compact packaging of electronic equipment the chip is interfaced with a thin heat spreader. As the package is made thinner, the coupling between heat flow through TIM and that in the heat spreader becomes stronger. Thus, a TIM characterization system for considering the heat spreader effect is proposed and demonstrated in detail in this paper. The TIM test apparatus developed based on ASTM D-5470 standard for thermal interface resistance measurement of high performance TIM, including the precise measurement of changes in in-situ materials thickness. Thermal impedances are measured and compared for different directions of heat dissipation. The measurement of the TIM under the practical conditions can thus be used as the thermal criteria for the TIM selection.

Today, offshore design field is concerned with system integration such as CIM(Computer Integrated Manufacturing), PDMS(Product Data Management System) and EDMS(Engineering Data Management System) in order to cope with the change of engineering specification as owner's requirements during construction stage of the project. This paper deals with the case study that describes about the efficient interface between material control system and 3D CAD system to support the design process in offshore industry using design rules involved the designer's knowledge. In this paper, we constructed an information system, called knowledge-based CAD interface systems, which is composed material code management system and 3D specification generator which automatically creates 3D catalogue anti specification by linking the material code, called short code, and the specification components of the 3D CAD system. As a result of the construction, it is possible to maintain consistency of the design process, and through reduction of the design processing time and improvement of the design process, competitiveness is improved.

최근 아이폰을 필두로 급부상하는 스마트폰의 정전기식 입력 장치에서는 펜 입력장치나 감압식 입력 장치를 위해 만들어진 제스처기반 인터페이스가 적합하지 않다. 손가락 튕김 인터페이스는 기존의 제스처기반 인터페이스에서 사용했던 플릭 제스처와 달리 명령을 적용시킬 대상과 명령을 동시에 선택함으로 작업 단계를 절반으로 감소시킬 수 있다. 뿐만 아니라, 멀티터치 인터페이스와 병합하여 사용함으로 다양한 메뉴 지원이 가능하여 복잡한 제스처를 학습할 필요가 없고, 정전기식 입력 장치 장치에 사용하기 적합하여 입력 오류를 최소화 시킨다. 본 연구에서는 정전기식 입력 장치를 가지는 스마트 폰 장치에서의 파일 관리를 빠르게 해주는 다중 손가락 튕김 인터페이스를 설계하고 구현한다. 실험에서는 사용자 평가를 통해 제안하는 인터페이스가 정전기식 입력 장치에서 기존 방식보다 유용함을 증명한다.

To develop a watershed management plan for protection of the lake water quality, the linkages among land use activities, stream water quality, and lake water quality must be understood. This study conducted to develop a Decision Support System(DSS) for the reservoir water quality managers and a comprehensive watershed management plan. This DSS has three main components; database, interactive decision model, and data delivery interface system. Graphic User Interface(GUI) was developed as the interface medium to deliver the data and modeling results to the end users. Water quality management scenarios in Yongdam reservoir consist of two parts. One is the watershed management, and the other is water quality management in the reservoir. The watershed management scenarios that were evaluated include as follows : a removal of point sources, control of waste water treatment plant, reductions in nonpoint sources, and the management of developed land. Water quality management scenarios in the reservoir include to install a curtain wall and to operate an algae removal system. The results from the scenario analysis indicate that the strategy of the reservoir water quality management can promise the best effectiveness to conserve the quality of reservoir water. It is expected that many local agencies can use this DSS to analyze the impact of landuse changes and activities on the reservoir watershed and can benefit from making watershed management decisions.

This article introduces developing trends of an 'Ubiquitous Interface' as an access method for use of various network resources, such as public wireless networks and un-licensed wireless networks in ubiquitous sensor network environments, without troublesome settings or operations by users. 'Ubiquitous Interface' is a relatively wide sense meaning not only physical interface of specified device or between processors, but anything method for access USN. These 'Ubiquitous Interface' able to provide seamless services that adapt autonomously to the user's movements and changes in the state of wireless resources. Recently, strongly recommended current technologies are RFID, NFC, Multi-mode mobile terminal, UMA mobile terminal and Wearable computer as a future ubiquitous interface. These technologies are have to have flexibility and multiple physical communication channels for seamless service hand over and serve easy connection at huge USN to user. Also, they have to must have flexible software structure. Finally, through the 'Ubiquitous Interface', we will be experience of seamless communication and realize a real liberty of communication.

In this paper, the Power Management System(PMS) which based on a decision making system according to power strategy is proposed and implemented. PMS is designed to have functions of power monitoring. controlling, synchronizing load sharing and monitoring of driving engine, etc. PMS consists of the internet communication system(ICS). Remote Management System(RMS) and Sensor Driver System (SDS) ICS transmits the monitoring and supervisory data via Internet to Remote Management System(RMS) in real-time SDS detects various power system data on local generator and utility via I/O interface system. I/O interface system receives various status data and outputs control signals. Implemented PMS is tested with dummy signal to verify proposed functions and shows good results. For future study implemented PMS will be tested under real load condition to merchandize.

Designing mobile Interfaces is fundamentally different from designing online interfaces. Not only are there differences in underlying technologies, but also in the way people use mobile Interfaces. If these differences are not taken into account in designing mobile interfaces, mobile services are likely to fail. If mobile services do not deliver what people want, these services will fail no matter how excellent the underlying technology is. The user interface design commonly used in mobile services is based on multi-layered approach, which is not very user-friendly. A well designed single layered user Interface will be more user friendly than the conventional one and it will be having edge over others. However, it is quite difficult to Provide a single layered user Interface in a small screen. This study aims at examining how design attributes of mobile interfaces affect customer preferences. In order to explore customer preferences to each design attribute of mobile interfaces, we measure and analyze customer's WTP (Willingness To Pay) toward their different interface designs. Ultimately, throughout the study, we try to answer how to design mobile interfaces in small screen of mobile devices. In addition, we propose an optimal design solution that customers likely prefer.
