Though the interest for the construction of ubiquitous city (u-City) has been increased in many researches, many of those efforts are still done somewhat separated ways such as from the perspective of architectural design of urban city or from the perspective of underlying ICT (Information and Communication Technology) implementation. Since there are various services and technical components involved in u-City implementation, those separated approaches can cause much troubles while implementing u-City. In addition to this, because u-City components are continually changing and expanding, to cope with this evolution, many researches about the infrastructure of u-City should be done in a systematic way while integrally considering various perspectives of u-City. In this research, by combining WBEM/CIM standards to GMA (Grid Monitoring Architecture), we could provide WBEM/CIM design that is usable for u-City implementation. In contrast to the conventional research that is still abstract, our study presents concrete and implementable u-City infrastructure model. We hope our result will be a valuable reference for the other u-City infrastructure-related researches.

Purpose: As medicare services have gotten spreaded, clinical laboratory has been dominant position. So, it has been acted for quality control and clinical pathology accreditation. But there has been quite deficient information to evaluate working space and technical standards of medical laboratory for accreditation. This study goals to figure out accreditation standard and design guideline for clinical laboratory, and to give safe and efficient design information. Methods: This study has been searched by literature for accreditation standards and design guidelines of clinical pathology in USA, UK, and Germany. Results: Three countries have accredited based on working lab space, staff space, storage space, patient space and health and safety equipment. Design guidelines of three countries commonly have focused on worktable layout, worktable distance and module, and specific laboratory biosafety level. And USA guidelines stress on the architectural design such as design process and passage distance for escape, UK stress on the efficiency as functional work flow and construction cost, lastly Germany design guidelines stress on the operator's safety distance and workstation. Three countries have not only accreditation standards but also design guidelines for more specific quality management, separating from accrediting institute. Implications: In korea, it has been needed to make clinical laboratory design guideline for the safe and efficient environment and reliable and competitive medical service.

Local government has constructed GIS DB for efficient business achievement and effective management of complex city facilities and has been developing and utilizing application systems, such as Underground Facility Management System Road Management System and so on. However, Facility Management System is providing functions for business, but not for GIS DB's maintenance. City facilities GIS DB managed by GIS technical expert collects basic figure and attribute information through survey and field investigation and is constructed via complex process, such as structurize editing etc. So it has been concerned that the update and confidence of CIS DB can be lower if a business man who does not have enough experiences about Facility Management System operates it by himself. Therefore, functions that enable business users to operate Facility Management System easily should be provided.

The objective of this study was to examine the hydrogeochemical and microbiological characteristics for stable maintenance of coastal LPG storage cavern. Cavern seepage water and groundwater in the vicinity of the LPG storage cavern were sampled and analyzed (February, May, August and October 2007). Groundwater samples of propane cavern showed high pHs of 8.1~12.4 due to dissolution of cement grouting materials that had been applied during the well and cavern construction. The EC values showed distinctive seasonal variation. The negative ORP indicated reduced condition. The seepage and surrounding groundwater are classified as Na-Cl type, which represents seawater effects. All of aerobic bacteria, anaerobic bacteria, slime forming bacteria and sulfate reducing bacteria were less than 500 CFU/mL, which indicated that there was no abrupt increase of bacteria in the cavern. Therefore there exist no hydrochemical symptoms to indicate unstable conditions of the cavern operation. However, regular and continuous monitoring is essentially required.

The purpose of this study is to present effective basic data for business management through analysis of importance and performance of personal information protection of the elderly welfare center workers. For this purpose, the questionnaire on the protection of personal information was reconstructed based on the diagnostic level of the personal information security management level of the public institution and the questionnaire was conducted on 105 employees of the elderly welfare center in Chungbuk area. Based on the responses to the importance and the degree of performance of the personal information protection of the elderly welfare center employees, technical statistics and corresponding sample T-tests were conducted and the importance-performance analysis (IPA) was used. Followings are the results of this study: First, there is a statistically significant difference between the importance and the implementation of the management system for the protection of personal information of the workers in the elderly welfare center, establishment and implementation of protection measures, establishment and implementation of infringement measures. Second, IPA analysis on the protection of personal information of the workers in the elderly welfare center shows that the establishment and implementation of protection measures are the areas to maintain good performance. Third, in IPA analysis of the sub-factors of the personal information protection of the workers in the welfare center of the elderly, in the construction and management of the management system, in performing the role of the personal information protection officer and establishing and implementing protection measures, The factors of prevention of information disclosure and exposure and the safe use and management of personal information processing system were analyzed as areas requiring intensive improvement. This study is meaningful as a basic research that can raise the awareness of the personal information protection of the workers in the elderly welfare center and induce the improvement of the related work.

The penetrated chloride in concrete has different behavior with mix proportions and local exposure conditions, even in the same environments, so that it is very important to quantify surface chloride contents for durability design. As well known, the surface chloride content which is a key parameter like external loading in structural safety design increases with exposure period. In this study, concrete samples containing OPC (Ordinary Portland Cement), GGBFS (Ground Granulated Blast Furnace Slag), and FA (Fly Ash) had been exposed to submerged, tidal, and splash area for 5 years, then the surface chloride contents changing with exposure period were evaluated. The surface chloride contents were obtained from the chloride profile based on the Fick's 2nd Law, and the regression analysis for them was performed with exponential and square root function. After exposure period of 5 years in submerged and tidal area conditions, the surface chloride content of OPC concrete increased to 6.4 kg/m³ - 7.3 kg/m³, and the surface chloride content of GGBFS concrete was evaluated as 7.3 kg/m³ - 11.5 kg/m³. In the higher replacement ratio of GGBFS, the higher surface chloride contents were evaluated. The surface chloride content in FA concrete showed a range of 6.7 kg/m³ to 9.9 kg/m³, which was the intermediate level of OPC and GGBFS concrete. In the case of splash area, the surface chloride contents in all specimens were from 0.59 kg/m³ to 0.75 kg/m³, which was the lowest of all exposure conditions. Experimental constants available for durability design of chloride ingress were derived through regression analysis over exposure period. In the concrete with GGBFS replacement ratio of 50%, the increase rate of surface chloride contents decreased rapidly as the water to binder ratio increased.
