In Korea, even though many aspects of medical care system for the elderly have been considered. Until now, most people have realized that the conceptualization range of geriatric hospital is the same as recuperation hospital. However the recent geriatric hospital includes a short term treatment like general hospitals, together with that it has a tendency to increase the propotion of rehabilitationby the Introduction of the concept of active rehabilitation treatment for returning to society. Unlike the general hospitals, geriatric hospital has got different characteristics in a managing and patient. However this is not a concrete standard of faacilities by the law of health welfare and medical. So these kinds of research will have to keep continuing. What I want to say In this study is that the prominence of information, which is based on the existing data analysis, is what forms my latest projects that engage with a wider repertoire of strategies and approaches toward architectural problem.

Fault management of virtualized network environments using user-driven network provisioning systems (NPSs) is crucial for guaranteeing seamless virtual network services irrespective of physical infrastructure impairment. The network service interface (NSI) of the Open Grid Forum reflects the need for a common standard management API for the reservation and provisioning of user-driven virtual circuits (VCs) across global networks. NSI-based NPSs (that is, network service agents) can be used to compose user-driven VCs for mission-critical applications in a dynamic multi-domain. In this article, we first attempt to outline the design issues and challenges faced when attempting to provide mission-critical applications using dynamic VCs with a protection that is both user-driven and trustworthy in a dynamic multi-domain environment, to motivate work in this area of research. We also survey representative works that address inter-domain VC protection and qualitatively evaluate them and current NSI against the issues and challenges.

The purpose of this study is to compare the seismic resistant capacity inherent in ductile moment resisting frames using two different joint modeling. The difference between these two models is the capability for considering the panel zone deformation. For this purpose, 5 story steel moment frame is designed in compliance to the Korean seismic design provisions and the steel structure design standard. Nonlinear Static Procedure(NSP) and Nonlinear Dynamic Procedure(NDP) of this structure are carried out using two different joint models. Based on the results of NSP and NDP, the sensitivity of the response to analytical modeling is appraised. Also, it is proposed that for the highrise steel structures, the joint deformation should be accounted properly by the analytical model.

From the optimal system specifications of optical parts in rear projection TV focused on competitive price and performances, we designed and developed projection lens which is able to be used on current broadcast standard NTSC and HDTV in common. Through the serial processes, which are initial design of all aberrations free, aspherization of the plastic lenses, optimization with tolerances and manufacturability, and athermalization, the lens was designed. The developed CRT-lens ass'y could display the 40-55 inches image and it's resolution is more than 1000 TV-lines.

Because of rapid technological advancements, increased data rate support has become the key criterion for future communication medium selection. Multimode optical fibers and multicore optical fibers are well matched to high data rate throughput requirements because of their tendency to support multiple modes through one core at a time, which results in higher data rates. Using the numerical mode solver OptiFiber, we have designed a concentric core fiber by investigating certain design parameters, namely core diameter (µm), wavelength (nm), and refractive index profile, and as a result, the number of channels, material losses, bending losses, polarization mode dispersion, and the effective nonlinear refractive index have been determined. Space division multiplexing is a promising future technology that uses few-mode fibers in parallel to form a multicore fiber. The experimental tests are conducted using the standard second window wavelength of 1,550 nm and simulated results are presented.

This paper proposes a Product Data Management (PDM) system architecture that supports end-user computing for small and medium businesses (SMBs) in Korea to build and maintain efficient and sustainable information systems for their product development. Its open database with relational tables enables existing common application programs such as Microsoft office suites to access product data in PDM systems. In addition, the interactive query processor provided by database management systems helps design engineers to build ad hoc queries in standard SQL database language to response different data requirements during their product development. The PDM architecture with the open database allows design engineers or technical staffs in SMBs to build and maintain their application programs for product development by themselves. To show the feasibility of the proposed architecture, this study implemented a prototype PDM system based on the architecture and database, and represents real-world product data with the implemented PDM system.

In this paper, we propose a Service-adaptive Tactical Data Transmission Protocol (STTS) based on Satellite Communications with narrow bandwidth. STTS is designed to provide additional field for scalability and scheduler for reliability of transport stream protocol based on digital broadcasting standard, DVB-S and DVB-S2. It is also verified the effects of lost data packets with narrow bandwidth through the simulator by traffic model and re-transmission of critical data, and checked the design considerations based on STTS system.

Recently, the vehicle consists of a variety of In-vehicle networks. But each network uses its own protocol so it is difficult to communicate with others. For this reason, standard format needs to communicate between networks. Therefore, in this paper, we design the XML schema which focuses on expansibility for communicating in networks and implements the XML build and parser tool for the interoperability of in-vehicle networks based on XML schema.

Because depth of deposit is deeper as well as compressibility is very larger than the other regions in Korea, behaviour of settlement at Nak-Dong river estuarine causes hot issue at ground improvement. Defined properties for design differ from measurement. Therefore it affects cost of construction. This study presents design standard to engineers as it defined properties of compressibility at Jangyu Area of Nak-Dong river estuarine. To search value of representation for region, back analysis was performed using the measurement. To verify that, the measurement of recently designed site was confirmed, and the cost of construction with properties of consolidation was calculated.

Korea Gas Corporation(KOGAS) have constructed a gas flowmeters' calibration facilities at Jungdong Bucheon. The facilities consisting of 6 reference turbine meters can perform calibrations of large capacity natural gas flowmeters up to $9,600 m^3/h$ at 95 kPa. This large capacity and high pressure natural gas facilities is traceable to the national standard of gas flow rate (KRISS). In this article the motive of construction and description of design are summarized.
