Recently, the public offices are going to be an important role of CIP(City Identity Program) and be a center of citizen's community activities. So, the aspect of the universal design (UD), the space performance assessment for a disable user is invaluable to designing the public office spaces. Purpose of this paper is to provide basic data for better design of public office space based on UD(universal design) principle. Conclusion based on the finding are as follows; First, checklist of environmental assessment for public space was composed of 7 basic principles of UD and 3 additional principles(aesthetic appreciation, maintenance and eco-design). Second, as the result of assessment, accessible and inclusive design is more necessary. Third, local characteristics should be developed and managed deliberately as to public space design. As the result of that, public office space design should an important part of reducing the isolation that was caused by physical and social disability. From now on, in public office space design, the integrated and continuous design program that is based on UD principle and eco-design will be necessary.

Objectives: In this paper, the survey on internet usage patterns of health consumers was conducted and analyzed in order to determine internet health information assessment criteria for providing correct consumer health information on web-sites. Methods: By using a survey questionnaire with 16 questions on general information and 20 questions on internet health information, data were collected from September 16 to 25, 2005 from 476 participants through an internet web site, http://www.hp.go.kr. Frequency analysis, t-test, and multiple regression were used in order to analyze the difference in assessment criteria, factors influencing assessment criteria, factors influencing user satisfaction, etc. Results: General characteristics of the study population were: the persons over age 40 were the smallest age group; women were accounted for 74.2%; and the persons with average income were the largest income group; and the persons with average health status were the largest health group. Most widely used health information were: exercise, disease, and diet, in order. There was significant difference(p=.001) in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. There was no significant difference in other assessment criteria. We also found that contents of websites and easy to use were more important factors than elucidation of information providers and information sources including speciality of information in quality assessment criteria of internet health information. Discussion and Conclusion: Results of this paper were compared with the previous studies from the literatures. Contrary to the previous studies in the literature, there was significant difference in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. In order to apply the study results to develop health contents for consumer, there is a need for further upgrade the proposed assessment criteria based on expert opinion.

Web-based PMIS (Project Management Information System) has played significant role in construction management processes in Korea. As the use of web-based PMIS increases, regular quality assessment to identify user's requirements is necessary. However, there have been rare research efforts for quality assessment of web-based PMIS. This study aims to assess the quality of web-based PMIS, especially ASP-PMIS (Application Service Provider based PMIS) that is widely used in Korean construction industry. The assessment factors of ASP-PMIS quality were adopted from previous research and empirically confirmed using exploratory factor analysis. ISA (Importance-Satisfaction Analysis), which is a variation of original IPA (Importance-Performance Analysis), were selected for the assessment and analysis method in this research. A total of 253 completed questionnaires, composed of 23 assessment items, were collected from the ASP-PMIS users in Korea (construction managers and constructors), and they were used to analyse the quality of the systems. Some possible contributions of this research are: it introduces a simple and easy-to-use tool for assessing the quality of ASP-PMIS with a set of quality assessment factors that are selected from previous researches and empirically tested; it provides the quality assessment results of ASP-PMIS in Korea so that ASP-PMIS providers in Korea can understand the users' opinion on their systems; it also identified that the urgent factors that require immediate attention to improvement. However, further researches are to be required on the following areas: enhancing the quality assessment factors in terms of their relation to the success of ASP-PMIS and to the users' performance; assessing and analyzing the quality of individual ASP-PMIS; establishing continuous improvement systems institutionally and instrumentally.

FPSO is widely used to develop deep sea oil fields and HHI has constructed ten(10) FPSOs. During these constructions, relevant structural design criteria such as yielding, buckling, fatigue, collision and impact strength were applied to verify structural safety. To apply the buckling strength evaluation for structures, the critical buckling stresses and applied stresses of relevant panels should be calculated. The plate and stiffened panels are to be idealized, which are needed much time and efforts by designers. Therefore, program development is necessary in order to evaluate the buckling strength conveniently and accurately. In this study, the buckling strength assessment system by using offshore code, DNV-RP-C201 was developed under MSC/PATRAN, pre-post program of finite element method. Graphic user interface program is written in MSC/PATRAN PCL functions. Source program to evaluate the buckling strength is developed in FORTRAN programming languages. The developed program is verified by comparing with the results of the Nauticus Hull developed by DNV Classification Society, and applied to the marine construction project conducted by Hyundai Heavy Industries LTD.

This study is intended to propose a systematic approach for reliability-based assessment of life cycle cost (LCC) effectiveness and economic efficiency for cost-effective seismic upgrading of existing bridges. The LCC function is expressed as the sum of the upgrading cost and all the discounted life cycle damage costs, which is formulated as a function of the Park-Ang damage index and structural damage probability. The damage costs are expressed in terms of direct damage costs such as repair/replacement costs, human losses and property damage costs, and indirect damage costs such as road user costs and indirect regional economic losses. For dealing with a variety of uncertainties associated with earthquake loads and capacities, a simulation-based reliability approach is used. The SMART-DRAIN-2DX, which is a modified version of the well-known DRAIN-2DX, is extended by incor-porating LCC analysis based on the LCC function developed in the study. Economic efficiencies for optimal seismic upgradings of the continuous PC segmental bridges are assessed using the proposed LCC functions and benefit-cost ratio.
