Recently, Web-based Survey has attempted to overcome the limitations of Paper-based survey. This method is more effective in costs and time use than traditional methods, also help respondents to understand and interest in the survey. Especially for the elderly, web-based survey is effective survey tool, because audio-visual material could be provied. The purpose of this study is to evaluate the effectiveness of two kinds of methods which were web-based survey and paper-based survey, focused on elderly residents' needs for ubiquitous home service. The participants were older than 60 and divided into 2 groups, web-based survey and paper-based survey, each group was controlled over by age, gender, computer skill. For this study, elderly residents conducted a survey passed through 2 steps, the first was residents' needs for ubiquitous home services, the second was an evaluation of survey methods. Finding were as follows : first, there was no difference between the two groups in needs for ubiquitous home service, so survey itself can not make a difference in survey results. Second, respondents of web-based survey were more interested in and felt easier about method that they conducted than ones of paper-based survey. Finally, Web-based survey will be more effective method to be figure out the need of the elderly who are familiar with computer.

Among the mainstream of this society has quickly adopted computer technology as part of their daily life, the ever growing group of elderly people, which will increase from 7% of the population in 2000 to being 14% just 18 years later, has been being exposed to computer using environment more than ever before. According to the survey of Korean government in 2005, the number of the elderly using computer has been rising actually, so web-based survey to identify housing needs of the elderly seems to have lots of possibilities as a useful tool for them. This study aims at comparing web-based survey tool with paper-based one, developed to identify the elderly needs on digital home planning. Experimental method and in-depth interview were employed. The participants were divided into 2 groups, web-based and paper-based survey group. Each group was controlled over by age (average 60 years old), gender and computer skill. As a results, web-based survy tool was revealed as effective to clearer understanding and causing more interests and more available, but less easy to handle than paper-based survey one. Through the in-depth interview, web-based survey tool was identified as a more effective method to figure out the needs of the elderly who are familiar with computer.

This study evaluated the consistency between the web-based and paper-based mibyeong and cold-heat pattern questionnaire, the Korean medicine-based tool for diagnosing and classifying health status. First, a web-based survey was conducted on 72 ordinary people; subsequently, a paper-based survey was conducted after a certain time interval. The equivalence between the web-based and paper-based surveys was evaluated on the basis of the consistency between scores using the Intraclass Correlation Coefficient (ICC) and Bland-Altman methodology. The mibyeong questionnaire showed high reliability for the web-based and paper-based surveys (ICC=0.95, 95% CI 0.92 - 0.97), and the cold-heat pattern questionnaire showed high reliability for both cold syndrome (ICC=0.98, 95% CI 0.96 - 0.99) and heat syndrome (ICC=0.9, 95% CI 0.83 - 0.93). The difference in average scores between the two survey methods was -0.25 for the mibyeong survey, -0.17 for the cold syndrome, and 0.11 for the heat syndrome, showing a similar pattern. Among the respondents, 84% showed positive satisfaction with the web-based survey, and 80% preferred the web-based survey. Overall, this study confirmed the reliability and feasibility of the web-based survey methods for the mibyeong and cold-heat pattern questionnaire. This could be a useful tool for the follow-up of subjects in long-term cohort studies.

This paper proposes a Web Based Online Outage Cost Assessment and Information System(WOOCAIS) for power system outage cost assessment. The proposed WOOCAIS is a kind of web based survey method for outage cost assessment. While conventional survey methods have done outage cost assessment based on survey paper lists collected by post mail or visiting customers, the proposed WOOCAIS is a web based online survey operation and assessment system. Therefore, it can curtail expenditure for survey and also is more convenient than conventional method. It will be set up for actual outage cost assessment system of KEPCO in South Korea in the near future. The WOOCAIS will be applied in various research and actual planning and operation areas. First of all, the assessed results may be not only applied as one of objective function for generation system and grid expansion but also operational planning problems in power system.

In many cases, the measurement error variances may be functions of the unknown true values or related covariates. This paper considers design-based estimators of the parameters of these variance functions based on the within-unit sample variances. This paper devotes to: (1) define an error scale factor $\delta$; (2) develop estimators of the parameters of the linear measurement error variance function of the true values under large-sample and small-error conditions; (3) use propensity methods to adjust survey weights to account for possible selection effects at the replicate level. The proposed methods are applied to medical examination data from the U.S. Third National Health and Nutrition Examination Survey (NHANES III).

The statistical survey and analysis is much restricted to time, space and material. The statistical survey and analysis could hardly resume. The statistical survey and analysis is very important to create various and accurate information. The statistical survey and analysis which is not a expert knowledge have many problems in productivity of information, reliability and etc. In this paper, we study the design and Implementation of web-based statistical survey and analysis consulting system which a client meet easily a statistical expert on the web.

Information system outsourcing induces firms to concentrate on the core competence and to improve business value by utilizing specialized information systems outsourcing vendors. However, for those strategic effects, the outsourced information systems should guarantee a certain service level. Now companies are considering to adopt SLA(Service Level Agreement) as a method to check the service level of the outsourced information systems in quantitative terms. On the contrary, customer satisfaction survey supports qualitative analysis, and helps companies to understand the qualitative effects on information system more systematically. Recently, the growing use of the internet makes customer satisfaction survey to be carried out on the web. For that reason, lots of researches related to web survey have been performed. But these researches are just focused on finding out only items to be measured and the effect of web survey. In this paper, based on the service quality research model for information system outsourcing, we formalize and propose a web survey process, a system architecture, and a functional structure for information system outsourcing customer satisfaction survey. Additionally, we provide the implementation results for the web survey systems.

In this paper. we conducted an empirical study to investigate the design and weighting effects on descriptive and analytic statistics. We compared the regression models using the design-based approach and the generalized estimating equations (GEEs) approach with the model-based approach through the design and weighting effects analysis.
