Purpose: Rural emergency medical service (EMS) is inferior to urban EMS. In creating and providing emergency patient care, in rural areas, it is important to consider resources, patient volumes, geography, technology challenges, volunteer and provider issues, medical oversight, polities, education, communications, and financial concerns. In the current environment in Korea, it is necessary to design tailored and self-supporting rural EMS systems. For the development of a self-supporting model for EMS systems in rural areas, we have studied the EMS system in one rural area, Goheung County. Methods: We obtained data from a health institute center, the Gwangju emergency medical information center, three emergency medical centers, and the fire station in Goheung county. In order to survey resident’s perceptions about the local EMS system, we provided a questionnaire to 324 residents in Goheung County in March 2005. The advisory council for the EMS system analyzed problems at each step or component of the EMS service delivery process and suggested a model for self-supporting EMS service in Goheung County. Results: The status of the EMS system in Goheung County is inferior to urban systems. A lack of appropriately trained emergency personnel at every level of care has been identified in this area. It is hard to find public education programs. There are few communication systems available for emergency medical care and there are extended transport times and distance, both for responding to and transporting patients. Resident’s perceptions of the EMS system is unfavorable. The advisory council suggested an optimized plan to address the problems of the EMS system in Goheung County. A self-supporting model is suggested by the council. It is necessary to consider residents’ participation and to apply available resources in Goheung County. Conclusion: An ideal EMS system in Goheung County will be a self-supporting model requiring participation of residents and wise application of available sources. The first consideration in this model is institution of a public education program and recruitment and education of first responders in every village is suggested. The model recommends integration of the EMS communication system to provide quality emergency medical care.

In this study the feasibility of a dynamic gait for a given quadruped walking robot is investigated through a computer simulation of the walking with certain drivings of the actuators. Two planar inverted pendulums are used to represent the dynamic model of the leg of the walking robot. It's gait motion is assumed to be periodic and symmetric between left and right sides only with half cycle delay. The dynamics of the walking robot is simplified by introducing two virtual legs to produce two planar inverted pendulums in two orthogonal planes and on the basis that certain legs in pair act as one. The feasibility of the dynamic gait motion is established from the following two necessary conditions:(1) The position and velocity of a foot must satisfy the stroke and velocity requirements.(2) The gait motion should be periodic without falling down. The gait feasibility test was applied to a walking robot design showing the specific acceptable speed range of the robot in trot. Also it showed that the higher body height may produce the faster trot gait.

It is important to determine the positions of the hard points that can generate a desired kinematic characteristic in suspension design. To do such a thing, kinematic sensitivity and optimization were conducted. The cost function is total weighted sum of errors between desired and actual toe, camber, caster, kingpin angle, etc. Kinematic sensitivity was calculated for design variables such as hard points and these results were compared with finite difference method. Optimization was executed by BFGS method . And GUI program that makes this process handled easily was developed for McPherson, SLA, QT, Quadra-link.<br/>
