The spread of satellite image increases various services using it. Especially, 3D visualization services of the whole earth such as $Google\;Earth^{TM}$ and $Virtual\;Earth^{TM}$ or 3D GIS services for several cities provide realistic geometry information of buildings and terrain of wide areas. These service can be used in the various fields such as urban planning, improvement of roads, entertainment, military simulation and emergency response. The research about extracting the building and terrain information effectively from the high-resolution satellite image is required. In this paper, presents a system for effective extraction of the building model from a single high-resolution satellite image, after examine requirements for building model extraction. The proposed system utilizes geometric features of satellite image and the geometric relationship among the building, the shadow of the building, the positions of the sun and the satellite to minimize user interaction. Finally, after extracting the 3D building, the fact that effective extraction of the model from single high-resolution satellite will be show.

Purpose: The Purpose of the study was to suggest how the health manager use to be easy return-to-work of injured workers. Method: The data were collected by the health managers working at the 103 companies over medium size in Incheon, Gyoung-gi and Seoul through interview and report by themselves and analyzed by SAS V8 through t-test. Result: 1. The health managers are consisted of 2 kinds, one is health manager such as physician(10%) or nurse(81%) and the other is safety manager. The former works at the manufacturing company(62.9%), the latter at the service one(42.4%). 2. Management and counseling of occupational and non-occupational diseases, and high risk workers, health education, emergency care, worksite rounding, guidance of personal protector use, and health promotion services were highly performed by health managers. Comparing to these, safety managers performed guidance of job safety, safety management. The difference of two kinds of manager was significant statistically not only the aspect of general job but also related job to the workers of return-to-work after accident. Conclusion: This result shows that health manager can function as a care manager to the workers after return-to-work for adaptation to their job and rehabilitation bio-psycho-socially. But health managers don't have any regulations of encouraging injured workers to get their job again officially.

In this paper, we proposed WBAN system model to management an application that requires low rate data transfer in IEEE 802.15.4. We have to use different wireless sensor network technology to transfer different date rate and emergency message in medical application service. A suitable system model for WBAN and a WBAN MAC protocol in order to solve these existing system problems are proposed. Firstly, the priority queuing was applied to contention access period, and the system model which could guarantee transmission of a MAC command frame was proposed. Secondly, the MAC frame was newly defined to use the system model which was proposed above. Thirdly, WBAN CSMA/CA back-off algorithm based on data transmission rate was proposed to enhance data throughput and transmission probability of the data frame which does not have priority in the proposed WBAN system. The proposed algorithm is designed to be variable CSMA/CA algorithm parameter, depending on data rate. For the evaluation of WBAN CSMA/CA algorithm, we used Castalia. As a result of the simulation, it is found that the proposed system model can not only relieve loads of data processing, but also probability of collision was decreased.

To protect the life and property of the residence from diverse disasters, we have collected and analyzed the domestic and foreign residence evacuation plans. The results and proposals from the study can be summarized as in following. First, the contents and items in civil defense emergency evacuation plan guidelines should be stipulated more clearly and its' application should be extended. Second, uniformity must be established in non-coherent contents between cities and counties. Third, disaster-prone people are not considered in the evacuation plans. The disaster-prone people must be accounted by each cities and counties and an evacuation plan for them must be established. Fourth, most of the rooms for residence evacuations are second to third level, and they are defenseless against disasters like CBRNE. Considering these conditions, deploying transportation means that can support large-scale evacuations, quickly and effectively, must also be considered.
