This Paper analyzed simultaneous activities of the time use survey by Korea National Statistical Office to use data mining's association rule. The survey of National Statistical Office in 1999 considered general analysis for main activities like that personal care(eating), employment and study, leisure, travel by purpose. But if we use the association rule, we can found the ratio of simultaneous activities at the same time. And also we can found the probability that another activities practise if we act one particular activity. Using this association rule of data mining we can do more developed and analytical sociological study.

In this paper, we estimate the proportion of individuals having health insurance in a given year for several small domains cross-classified by age, sex and other demographic characteristics using the data provided by the National Center for Health Statistics(NCHS). We employ Bayesian as well as frequentist methodology to obtain small domain estimates and the associated measures of precision. One of the new features of our study is that we utilize the survey weights along with the model to derive the small domain estimates.

This study is to adjust the focus on the statistical survey about the rates of application for the 2005 Susi second semester admission to Universities in Daegu, Kyungbook. The decrease of population for university admission and the change of paradigm of selecting a field of specialization in university will have an adverse effect on ratios of admission. This is very important to the future of university in Daegu, Kyungbook.

The objectives of this study are to study and propose the learning elements and it's teaching methods for Information Ethics by expert survey. In recent days, Internet is the new field of our living, but teaching the students in elementary and secondary schools the subject of Information Ethics which purpose is to have positive attitude of utilizing Internet is not properly executed. The first step to teach Information Ethics in schools is to choose the learning elements in Information Ethics. Therefore, this paper is to choose the learning elements and re-arrange them with point of view to elementary and secondary schools. And more, in order to teach the students the learning elements of Information Ethics effectively, we propose the proper teaching methods to the learning elements by teacher's survey. The learning elements and teaching methods in Information Ethics is not the perfect guide to teach students in school, but the output of this study will be the good guide to revise the Information Ethics-related curriculums and product the textbooks about Information Ethics.

Data fusion is generally defined as the use of techniques that combine data from multiple sources and gather that information in order to achieve inferences. Data fusion is also called data combination or data matching. Data fusion is divided in five branch types which are exact matching, judgemental matching, probability matching, statistical matching, and data linking. Currently, Gyeongnam province is executing the social survey every year with the provincials. But, they have the limit of the analysis as execute the different survey to 3 year cycles. In this paper, we study to data fusion of environmental survey data using sas macro. We can use data fusion outputs in environmental preservation and environmental improvement.

Questionnaire survey on performance requirement of ship’s speed such as not only accuracy but also response and robustness were carried out, and the experiments to survey the GPS performances of static and dynamic characteristics were carried out simultaneously. In this paper, the questionnaire survey focusing on docking maneuvering, some analytic results of the survey, the results of GPS performance, and the possibility of adaptation for docking maneuvering on SDME and GPS are discussed. Consequently, from the results of questionnaire survey the performance requirement of ship’s speed in docking/anchoring maneuvering have need under 1cm/sec on the standard deviation, and speed information from GPS was adopted to use maneuvering information in docking/anchoring.

In this paper, we propose a study on the technology level survey and analysis of problems for improving the defense IT survey. Existing in 2008 and 2009, were surveyed and the documents were distributed. It's managed on system. It was surveyed 86 technology but, the selection method and content was simple. we surveyed and interviewed to work-related parties for improving and analyzed management system and documents. So we derived improvements. we selected defense IT from various aspects. and commissioned survey for document review and technology level to about 130 experts. The technology level is composed of the best technology weapon states, technology gap, spread effect, technology achievement time and research & development method.. We finally selected 40 technology, and suggested results of the technology level survey.

The proportion of micro-enterprises and self-employed in Korea is excessively high compared to that of major developed countries, and frequent start-ups and business closures are repeated, causing enormous damage to the national economy. In order to solve this problem, various studies are underway for micro-enterprises, and the government provides commercial district information analysis services using big data for micro-enterprises. Among the commercial district information analysis services, the commercial district information analysis of our village store operated by the Seoul Metropolitan Government is continuously improving its service to provide the big data analysis service related to micro-enterprises. Since the service was built by integrating big data provided by various organizations, however, there are limitations in data reliability, data analysis, and service composition. In order to overcome these limitations, this paper proposes a location-based survey system that can be analyzed in conjunction with big data-based commercial district services. The proposed questionnaire survey system established the basis for expending the big data commercial district analysis service by linking the survey information and commercial district information.

In the construction project, the design and the construction have been divided strictly. Because the design files of CAD library cannot be used directly in project quantity survey, we depend on manual handling.. It's because there has no interface between the system of the design and that of the construction. In this paper, by using the sizes and quantites of project design, we construct database model for automation of project quantity survey, and analyze the interface among the structure design files stored in design library of CAD system and the information of quantity survey, build a system which can survey the project quantity efficiently and evalulate the performance of this system.
