Despite many criticisms that topographic survey data for the official land price appraising collected annually using field survey method might be inaccurate, there is only few concrete research on it. This paper investigated whether the topographic survey data collected by a local government using field survey method is consistent with the data analyzed using the digital elevation model to examine its accuracy. The accuracy analysis indicated that 324 out of 1537 lots of land have inconsistent results which means the ratio of inconsistency is 17.36%. Among 11 areas studied, five had the inconsistency ratio above 20% while the worst one had 38.71%. The inconsistency ratio is generally higher for the rough terrain with irregular slope and high altitude while it is relatively lower for the terrain with smooth landform. The analysis results imply that there are limitations in investigating the topology by field survey method. Therefore, the official land price appraising policy should set precise criterion and change over to highly accurate geographic information analysis method to effectively and accurately examine topology, given the fact that the topology of the Republic of Korea has complicated features with irregular slope and altitude.

The Officially Announced Land Price System has a limit, that is required to be able to reflect changes in land constantly every year, to implement Land Characteristic Survey for calculating land price during a specific period and human resources with limited. The purpose of this study is to apply the 'National Territory Space Usage status Survey' method to survey part of the territorial feature status information inside of selected the target sites, considering the core survey items (land category, the state of land use, altitude difference, standard site inclusion, etc) in the areas surrounding Yeonshinnae Station in which three dongs (Galhyeon-dong, Daejo-dong, Bulgwang-dong) of Eunpyeong-gu, Seoul share borders with. Based on the given budget, the manpower and period was taken into consideration to sort a total of 2,041 lots and conduct surveys on all sites. This study will be able to diagnose the efficient idle human resource utilization and work process construction plan through pilot projects specialized for providing real estate information services in preparation for cases in which national territory information survey projects that provide various business model, as well as major future core projects of the corporation will be carried out.

The purpose of this study is to evaluate the accuracy of Network-RTK(VRS) survey for applying to Ground Control Points(GCPs) survey required for mapping aerial photographs. Network-RTK has been serviced by National Geographic Information Institute since 2007. On the basis of the global coordinates system(ITRF2000), the coordinates of GCPs determined by Static GNSS survey with relative positioning techniques were regarded as accurate values. The coordinates of GCPs were also determined by Network-RTK survey using two kinds of receivers, and then they were converted into the global coordinates system(ITRF2000) by applying suitable geoid model and coordinate transformation. These coordinates of GCPs were compared with those from Static GNSS survey. The root mean squares error (RMSE) of coordinate differences between Network-RTK and Static GNSS was ${\pm}2.0cm$ in plane and ${\pm}7.0cm$ in height. Therefore, Network-RTK survey that enables single GNSS receiver to measure positions in short time is a practical alternative in positioning GCPs to either RTK survey that uses more than two sets of GNSS receivers or Static GNSS survey that requires longer observation time.

Survey environment has recently been changed along with its bad conditions. Surveyors feel difficult to meet respondents because the number of one person-household and working-together-household has rapidly increased. With a growing awareness of protecting personal information, respondents no longer want to response to a questionnaire. To get responses form an increasing number of non-response houses and respondents who are difficult to meet, Korea National Statistical Office(KNSO) has changed its survey methods and thus introduced new survey methods, free from face-to-face interviews. A telephone interview has officially been allowed for some reasonable situations and it shows a tendency that the trend of interviewing method is moving toward Internet survey. This paper focuses on how survey methods should be changed with the use of IT in response to changes in the survey environment. Survey methods combined with IT have many excellent advantages, Korea has been an enviable World IT contest for a long time. If Korea can apply such an advanced IT environment to survey methods successfully, it will make a great contribution toward improving the survey quality. This paper also reviews which survey method is most appropriate for National Statistics as the survey environment has changed.

In generally, we use a method of the survey to forecast the economic demands and non-economic demands for a market trend. But we have a difficult problem to estimate the demand for the marketplace objectively because the survey with the non-response and the inadequate understanding on questionnaires did not provided the strong and uniform forecast. Here, we proposed a method compounded of survey and a statistical model to estimate the demand for the marketplace and discussed the mixture model applied to the service demand on an agency.

The corporate restructuring following the economic crisis in Korea has brought about fundamental changes in the structure and practice of employment relations. However the lack of information on processes and consequences of such changes hinder the appropriate policy making on shop-floor industrial relations. Correct assessment of realities an effective policy making require information on human resource management practices and structure of employment relations at the workplace level. This paper critically examines the experiences of workplace-employee integrated surveys carried out in advanced countries including Australia, Canada, and Britain, to extract methodological implications for such survey in Korea. We focus on the backgrounds of the surveys and practical issues involved in multi-level, longitudinal survey design.

Objectives The aim of this study is to survey the present scales of constitutional medical service market on the base of Korean medical service market following 2006, 2008 year survey. Methods This survey was conducted from Nov. 1 to Dec. 15, 2011 by offline mail. A questionnaire including personal information, general information, and management related to constitutional medicine of Korean medical institution was sent to each subject with a returned envelope. The subjects were asked to complete the questionnaire and 108 data were collected and analyzed. Results This study revealed that the 62% facilities of all Korean medical clinics in Korea are using constitutional medicine for patients. The proportion of constitutional medical service was 13.7% in Korean medical care insurance and 23.5% in total Korean medical service market. Conclusion It is assumed that the scales of total Korean medical service market seemed to be 3,974,425 million won and the scales of total constitutional medical service market seemed to be 929,404 million won.

In a situation when domestic construction market is expected to be stagnant, Overseas Information System for Construction Engineering (OVICE) is operated to support the construction SMEs that advance to the global market. In this study, we aimed to improve the quality of information service by providing direction of information provision, by comparing expert questionnaire with information system user statistics. For statistical analysis of information systems, to improve the efficiency of statistical analysis that is difficult to prioritize, K-means clustering is used for more efficient analysis. As a result, analyzing the difference between the survey results and the information system statistics, we were able to identify improvement point of information provision in the system and important contents that were not highlighted during the survey.

IT investments of hospitals are growing exponentially and various information systems such as OCS (Order Communication System), EMR (Electronic Medical Record), PACS (Picture Archiving and Communication System), ERP (Enterprise Resource Planning) have been implemented at a number of hospitals in Korea. We have surveyed and analyzed the current status of hospital information systems of major hospitals in Korea, and proposed an information strategy for e-Hospital implementation. Firstly, implementation status of major subsystems of HIS such as OCS, PACS, and EMR has been surveyed and types of IT personnel management have been examined. Based on the field survey result, an information strategy for e-Hospital implementation has been proposed, that can be referenced by hospitals to build their own information strategy. We expect that the study result can contribute to understanding the present status and issues of HIS and information strategy planning of hospitals.
