Purpose: The purpose of this study was to compare the effectiveness of case management in elderly medicaid beneficiaries according to geographic location. Methods: Data were collected from 23,633 elderly medicaid beneficiaries assigned from over users of medicaid. We used the need assessment tool developed by the government, which consists of 19 items with four subscales. Results: Among elderly medicaid beneficiaries, statistically significant differences in effectiveness of case management were observed for quality of life, self-care competency, medical care utility, and support system. Differences in case management effectiveness were higher in urban areas than in metropolitan or rural areas. Conclusion: The differentiated and tailored intervention model based on characteristics of participants, resource distribution, and geographic location may be needed for effective case management for elderly medicaid beneficiaries.

This paper deals with a construction plan of hydrogen fueling stations on express highways using geographic information system. We analyzed the existing hydrogen fueling stations and production facilities to construct the hydrogen supply system to satisfy the hydrogen demands. Also, we suggested the necessary number and locations of hydrogen fueling stations on express highways for operating fuel cell vehicles. As a result, we need to construct at least 6 hydrogen stations on express highways in 2020 and 14 hydrogen stations in 2025. In 2030, when fuel cell vehicles are expected to spread over the whole nation, 114 hydrogen stations are needed to construct on express highways. This study mainly utilized the information of distances between hydrogen production facilities and fueling stations. However, we need to analyze the other factors such as traffic and income data. Also, it is necessary to make a suitable construction plan of hydrogen fueling stations that should be constructed on each district using geographic information system.

In this paper, we propose the geographic information systems that is able to build geographic information effectively by creating 3D topography after extraction surrounding terrain information through the video shooting in the CCTV camera. We also propose tracing method for object recognized through the video shooting of camera and recognition method which is whether or not the terrain change according to success or not of tracing the object. We apply this method in the industry field we can build a geographic information close to the actual terrain, but also can be used for security, surveillance and tracking system.

In order to meet the users' demand, who needs faster and more accurate data in geographic information, it is necessary to obtain and process the data more effectively. Now more effective data obtainments about geographic information is possible through the development of integration technology, which is applied to the field of geographic information, as well as through the development of hardware and software engineering. With the fast and precise correction and update, the development of integrate technology can bring the reduction of the time and money. To obtain fast and precise geographic information using Aerial Photogrammetry method, it is necessary to develop Airborne GPS/INS integration system, which makes GCP to the minimum. For this reason, this study has tried to develop a system which could unite and process both GPS and INS data. For this matter, code-processing module for DGPS and OTF initializaion module, which can decide integer ambiguity even in motion, have been developed. And also, continuous kinematic carrier-processing module has been developed to calculate the location at the moment of filming. In addition, this study suggests a possibility of using a module, which can unite GPS and INS, using Kalman filtering, and also shows the INS navigation theory.

It was investigated to develop the contents for the local government for the purpose of providing various and correct information. Especially it was focused to take advantage of spatial information techniques, GIS(Geographic Information Systems) and RS(Remote Sensing). The research site for this study was Muan-gun located at the south-western part of Korea, and this site has very high opportunities to became the central point for the economical and tourist industry. The regional information contents for Muan-gun was developed and composed of three elements, internet related, geographic information related and satellite imagery related elements These contents will make a contribution for the local government to present the regional information effectively and efficiently.

Geographic information systems are the crucial means in local governments to improve the diverse internal operations or service to citizens. A eat number of local governments have introduced GIS. However in spite of the rapid spread of GIS projects in local governments there are severe level differences of Geographic Information Infrastructure between medium or large cities and small cities or counties(Gun), especially in non-capital area. The differences are one of the main reasons of regional inequalities in local governments'administrative services. Thus this article suggested that the central government should place policy emphasis on improving the levels of geographic information infrastructure in small cities, counties(Gun) and especially non-capital areas.

In Korea, the railway history has more than 100 years and the KTX(Korean Express Railway) was launched on April 1, 2004. Nevertheless, the safety management of the railway has not been emphasized. Thus this paper proposed the novel frame of the railway safety management system which can secure the railway safety and administer the railway accidents via Management Systems from domestic to international. Secondly, we developed the prototype Management System for the railway accident based on GIS(Geographic Information System) by introducing the concept of "location". This Management System has two parts: space and attribute. Also it provides the map for emergency actions.

Today, satellite remote sensing and geographic information systems plays an important role as a advanced science and technology, and becomes a superpower tool of the study and research in various fields of Earth Science. This study reviews the application of satellite remote sensing and geographic information systems for many specialists in the fields of the fishery and ocean science. In future, satellite remote sensing and geographic information systems will be greatly used to observed, monitor and predict various phenomena associated with the fisheries and oceans, in order to seek safety in a natural disaster, and menage and conserve the fisheries and resources and the oceanic environments.

Response of buildings under seismic load is different according to fundamental period. It is provided in Korean Building Code(KBC2009) seismic response coefficient by fundamental period for seismic design of buildings. Recently, many researchers have studied on fundamental period and seismic response coefficient. However, studies on seismic design using Geographic Information System(GIS) are not sufficient. Therefore, this paper has analyzed on seismic response coefficient of buildings using ArcGIS. This paper can be evaluated efficiently for seismic analysis of structures. And this study will be used as basics of a reasonable seismic design using Geographic Information Systems(GIS).

The Mobile Mapping System using the vehicle equipped the GPS, IMU, CCD Cameras is the effective system for the management of the road facilities, update of the digital map, and etc. If the geographic information which is acquired by the Mobile mapping System can be transmitted in realtime, users can process what they want using the latest data. In this research, the effective method was suggested for the transmission of the geographic information acquired by mobile mapping System such as position data, attitude data, and image data in the wireless internet environment in realtime.
