The statistical method of human sensibility ergonomics is widely used for analyzing interior design because it has standard processes and it can help to get quantifiable results. However applying this method demands repeated intense work and great time and effort is required. In this study, a tool applying Web and virtual reality techniques for statistical human sensibility ergonomic interior design analysis is proposed and the key parts of the tool including database and interface are implemented. The database contains the sensibility adjective table and the physical interior design factor table for analyzing the relationship between human sense and physical design factors. Interface of the tool is implemented using Web technologies, so testers can evaluate interior design samples via standard Web browsers. The 3D control which is an important component of the interface is also implemented. Employing the suggested tool can reduce effort and time for evaluating human sense in Interior design field.

Insulating polymers and their composites have been widely used in various electric apparatus or cables. Recently, the effects of interfaces (metal/insulator or insulator/insulator interfaces) on electrical insulation have attracted much attention. However, interfacial phenomena in actual insulation systems and their physical backgrounds are not well understood yet. In this paper, the behaviour of charge carriers near the metal/polymer interface and its effects on conduction and breakdown phenomena are discussed. The metal/polymer interface strongly affects carrier injection, space charge formation and breakdown phenomena. Based on their experimental results, the physical backgrounds of the interfacial phenomena are explained.

This study focuses on the physical environment and human activity of the user of train toilets, on the analysis of factors needed to obtain reasonable toilet design and it also focuses on the understanding of the interface between its user. Moreover it proposes a module of the development process and methods of approaching the User Toilet Interface. The study so presents a design standard under which the concrete data of the characteristics and practicable range and the convergent demands accelerate to the module could be confirmed and criticized.

This paper describes the development of general purpose operator interface which uses a color graphics terminal with a touch-sensitive screen as the control console. Operators interact with a process through a collection of application-dependent displays generated interactively by users familiar with the physical process. The use of real-time operating system(iRMX-86) and multitasking results in a straightforward and reliable development which may easily be extended to support multiple devices of varying types in the control console.

Three kinds of high-speed signaling methods for synchronous DRAM (SDRAM) bus interface channels (PC-133, Direct-Rambus, and SSTL-2) were analyzed in terms of the timing budget and the physical transmission characteristics. To analyze the SDRAM bus interface channels, loss mechanisms and the effective characteristic impedance method were reviewed and the ABCD matrix method was proposed as an analytic and yet accurate method. SPICE simulations were done to get the AC responses and the eye patterns of the three SDRAM bus interface channels for performance comparisons. Recent progress and future trend for SDRAM bus interface standards were reviewed.

In this study, I have researched the theories about Gibson's real affordance and Norman's perceived affordance which are central fact of affordance, And I have examined the context of affordance in smart-phone interface which was consist of affordance and signifier with viewpoint of amalgamation of Gibson & Norman. The results of this study are as follows; The first, Gibson's real affordance is a physical space in ubiquitous environment that interact through the behavioral space is composed with physical space and electronic space. Norman's perceived affordance is mediated to electronic space and signifier makes a behaviroal space which provide the clue of interaction. The second, signifier can be categorized into visceral, behavioral and reflective signifier based on three brain actions which are visceral, behavior, and reflection. Through the categorization, we can grasp that behavioral and reflective signifies generate visceral signifier. The third, the context of affordance in smart-phone has the structure of circulation. The structure of circulation is as follows: Real affordance makes the perceived affordance, the perceive affordance makes the signifiers and the signifiers make new real affordance. This study could provide the theoretical basis for using signifier in smart-phone interface design.

The mechanical damage of concrete is normally attributed to the formation of microcracks and their propagation and coalescence into macroscopic cracks. This physical degradation is caused from progressive and hierarchical damage of the microstructure due to debonding and slip along bimaterial interfaces at the mesoscale. Their growth and coalescence leads to initiation of hairline discrete cracks at the mesoscale. Eventually, single or multiple major discrete cracks develop at the macroscale. In this paper, from this conceptual model of mechanical damage in concrete, the computational efforts were made in order to characterize physical cracks and how to quantify the damage of concrete materials within the laws of thermodynamics with the aid of interface element in traditional finite element methodology. One dimensional effective traction/jump constitutive interface law is introduced in order to accommodate the normal opening and tangential slips on the interfaces between different materials(adhesion) or similar materials(cohesion) in two and three dimensional problems. Mode I failure and mixed mode failure of various geometries and boundary conditions are discussed in the sense of crack propagation and their spent of fracture energy under monotonic displacement control.

본 논문에서는 유무선 통합 환경의 차세대 방통융합 서비스를 위한 기반 기술로서 다양한 액세스 망에 대한 다중 접속 인터페이스를 갖는 멀티모드 단말의 인터페이스 가상화 기법을 소개한다. 제안된 가상 인터페이스 기술은 멀티모드 단말의 각 물리 인터페이스에 대해 상이한 IP 주소를 할당하고 패킷 전달 시 이들 주소간의 변환을 수행하는 기존의 방식과 달리, 고정된 하나의 단일 IP 주소 만을 이용하여 다수의 물리 인터페이스들을 가상화하는 기능을 제공한다. 따라서 패킷 전달 시 IP 주소 변환 등 단말 기능 변경을 요구하지 않으므로 Proxy MIP와 같은 네트워크 기반 IP 이동성 제어 기술과 연계하여 적용하기에 용이한 장점을 제공한다. 또한 기존의 OS가 단일 단말 내의 상이한 물리 인터페이스에 대해 동일 IP 주소를 할당할 수 없도록 하는 제약사항을 극복함으로써 MBB(Make-Before-Break) 방식의 핸드오버 제어뿐만 아니라 BBM(Break-Before-Make), 다중 접속(Multi-connection) 등과 같은 다양한 방식을 모두 지원할 수 있는 장점을 갖는다. 제안된 가상 인터페이스는 네트워크장치 인터페이스 표준 규격으로 개발된 NDIS 라이브러리를 이용하여 구현되었으며, 테스트베드 구축과 시험 프로그램 개발을 통해 주요 기능의 시험 및 동작 결과를 확인할 수 있었다. 이러한 가상 인터페이스를 통해 멀티모드 단말이 이종 액세스 망간 핸드오버를 수행하는 도중에도 동일한 IP 주소를 이용하여 실시간 멀티미디어 서비스 세션을 끊김없이 유지하도록 지원하는 것이 가능하다.
