광용적맥파(PPG: photoplethysmogram) 신호는 심전도(ECG: electrocardiogram) 신호와 더불어 가장 많이 측정이 되는 생체 신호 중 하나이다. 광용적맥파 신호를 이용하여 측정할 수 있는 정보들은 혈류의 속도, 혈액 중 산소 포화도 등을 측정할 수 있다. 이들을 측정하기 위한 기반 정보는 맥박 정보이다. 광용적맥파 신호로부터 맥박을 측정하기 위하여 동적 잡음이 필수적으로 제거 되어야 한다. 기존 방법은 팔의 움직임을 나타내는 가속도 신호를 이용하여 동적잡음을 제거 하였지만 이는 계산 복잡도를 증가시켜 실시간으로 맥박을 추정하기에 어려움이 있다. 본 논문에서는 광용적맥파 신호만 사용하여 신호를 측정함과 동시에 맥박을 추정해내는 알고리듬을 제안한다.

Purpose: The aim of this study was to demonstrate that non-participation of physical therapists on the political decision-making committee results in invasion of their interests. Methods: To demonstrate the effects, we analyzed the change of medical insurance score decided by the Health Insurance Policy Deliberation Committee between 2001 and 2012 years, focusing on medical examination as the interest of the participation group and physical therapy cost as interest of the non-participation group. Results: Total medical insurance cost increased by 23.72%, on average. Medical examination cost increased by 23.90% and 37.66% in medical examination for new and established patients, respectively. However, physical therapy cost was reduced by 5.01%. The medical examination cost for physical therapy without medical checkup increased by 2.62%. Conclusion: This study shows that the physical therapy cost, related on the interest of the non-participative group in the Health Insurance Policy Deliberation Committee, rather decreased while the total medical insurance cost increased.These findings demonstrate the invasion of the non-participative group on the Health Insurance Policy Deliberation Committee. Thus, aggressive participation in political decision-making committee is necessary in order to protect and increase rights and interests of Korean physical therapists.

Purpose: The purpose of this study is to analyze health status of women working in traditional marketplace and their needs for public healthcare services. Methods: A descriptive survey of 500 women working at three traditional marketplaces was conducted. Results: street vendors' health status were much poorer than store merchants'. Furthermore, psychosocial factors like job stress and depression were increased in street venders. Thus, the public healthcare programs required by them included exercise programs (28.2%) and health checkup (26.8%). In addition, 31.2% of the participants reported that they needed visiting nursing care services. The rate of occupational health and safety or employment insurances was as low as 10.8%. Conclusion: Effective interventions including psychosocial factors for women workers at traditional marketplaces need to be developed based on these results. Also, it is recommended that public health care services such as outreach services and visiting nursing care services for women working at traditional marketplaces be provided. Furthermore, institutional provisions such as insurances for protecting these vulnerable groups' health are needed.

Emergency room process is very important in the whole hospital processes because it is first diagnosis for patient. Above all, triage is important activity which quickly diagnose the status of emergency patient and sets the priority for treatment. This paper analyzes the treatment process pattern by triage type. The results show that the treatment process after triage such as residence time, diagnosis and checkup type, and joint treatment are dependent on triage types. We can use these analysis results for improving the current triage system and developing the new triage system considering a domestic emergency medical service environment.

The application of analytical techniques for the rational determination of problems arising from management science and corporate management. In a way that is the opposite of the repair plan that can predict accurate results is increasing utilization of the complex-based analysis methodology. In this study, we examined the application of physical space and the methodological utilization of the pedestrian model analysis that applied the simulation to the Health Checkup Center. The conclusions are as follows. First, the spatial analysis and measurement for empirical research has confirmed that the efficiency assessment through the pedestrian model simulation can lead to an objective evaluation. Second, it seems to be able to reduce the queue through a change in the number of services of the low-pressure and the hearing laboratory, the recovery room with a high proportion of male disturbances and relatively long use time. The third, the spatial density analysis and the time required to reduce the density change in comparative analysis, and the spatial layout changes, the increase in the capacity of 80 people, approximately 16 minutes to shorten the process duration.

Stream Pilot Project, which began in May 2003 and finished in December 2003, was selected to develop effective methods applicable to nature-like streams. Stream restoration projects aim to maintain or increase ecosystem goods and services while protecting downstream and coastal ecosystems. Fields environmental monitoring such as flow discharge and precipitation were conducted along the Idong stream for amount of channel zone change in 2007. This study selected three monitoring positions to measure the water level and discharge of flowing water. A stage-discharge relation is obtained from direct discharge measurements for three stations by fitting an empirical relationship to the data set. Since discharge measures are made only for low flow conditions, a curve of discharge against stage can then be built by fitting these data with a power curve. And this study used data obtained from floodmark checkup as well as HEC-RAS model to analyze the hydrodynamic characteristics of monitoring sites. Reach-averaged hydraulic parameters for the supply reach were calculated from the small area's HEC-RAS model for Idong stream, and a HEC-RAS model used to analyze hydraulics for a period in 2007, after the stream was considered bank stabilization.
