초음파 로봇 검사시스템은 발전설비 등 상시감시가 요구되는 구조물의 감시를 위해 연구와 개발이 활발히 진행되고 있다. 그러나 이러한 설비의 구조물은 형상과 구조가 매우 다양하고 복잡하여 단순한 패턴으로 이동과 검사가 가능한 로봇으로는 상시감시에 한계를 가지게 된다. 복잡한 구조물의 정밀검사는 정교한 행동이 가능한 로봇 시스템이 필요하다. 로봇의 제어를 초음파검사 작업자의 손의 형상에 따라 직관적으로 움직이도록 한다면 보다 정밀한 검사 로봇의 개발이 가능할 것으로 판단된다. 폴리머 굽힘센서는 대변형의 측정이 가능하고 곡면에 적용성이 높아 최근 인체 형상 측정 및 재활보조 등 다양한 활용을 위한 연구가 활발히 진행되고 있다. 본 연구에서는 구조물의 상시감시를 위한 초음파검사 로봇이 작업자의 손동작에 따라 동작이 가능한 직관적 제어를 위해 폴리머 굽힘센서를 이용하여 사람 손의 형상 감시 연구를 수행하였다. 다수의 센서를 적용하여 손의 다양한 움직임을 추정하고 실험적 검증을 통해 사람 손의 형상에 따른 직관적 로봇의 제어가 가능함을 확인하였다. Ultrasonic inspection robot systems have been widely researched and developed for the real-time monitoring of structures such as power plants. However, an inspection robot that is operated in a simple pattern has limitations in its application to various structures in a plant facility because of the diverse and complicated shapes of the inspection objects. Therefore, accurate control of the robot is required to inspect complicated objects with high-precision results. This paper presents the idea that the shape and movement information of an ultrasonic inspector's hand could be profitably utilized for the accurate control of robot. In this study, a polymer flex sensor was applied to monitor the shape of a human hand. This application was designed to intuitively control an ultrasonic inspection robot. The movement and shape of the hand were estimated by applying multiple sensors. Moreover, it was successfully shown that a test robot could be intuitively controlled based on the shape of a human hand estimated using polymer flex sensors.

Purpose: This study aims to prove effects of an oriental medical complex therapy on vitiligo patients who have experienced the Eximer laser therapy. Method: The study conducted its investigation targeting these four patients who have not been observed with any satisfactory reaction to the Eximer laser therapy. The study analyzed the findings through the comparison on the pictures before and after the therapy. Result: After comparing the pictures, the study confirmed positive changes in the conditions of the patients. The oriental medical complex therapy turned out to be effective enough to treat the patients who have gone through the Eximer laser therapy before. Conclusion: Such result leads the study to a conclusion that the oriental medical complex therapy can be an effective way to treat these patients who do not have a satisfactory reaction to the Eximer laser therapy. In addition, the author of the study suggests that more clinical trials should be conducted.

Objectives : The aim of this study is to compare the improvement of Low back pain (LBP) depending on male Inpatient's Brachlalankle Pulse Wave Velocity (baPWV), Method : We evaluated 35 LBP inpatients who took pulse wave velocity test during admission at Jaseng hospital from November 2008 to september 2009. We used applanation tonometry method to measure pulse wave velocity and numerical rating scale to measure patient's improvement. Result : At admission, standard deviation of normal group's NRS was $7.44{\pm}1.67$ and high risk group's was $7.57{\pm}2.09$(P=0.678). After 5 days of admission, standard deviation of normal group's NRS was $5.67{\pm}1.94$ and high risk group's was $6.00{\pm}2.17$(P=0.680). After 10 days of admission, standard deviation of normal group's NRS was $4.00{\pm}1.80$ and high risk group's was $4.95{\pm}1.96$(P=0.281). After 15 days of admission, standard deviation of normal group's NRS was $2.89{\pm}1.62$ and high risk group's was $4.10{\pm}1.92$(P=0.124). At discharge, standard deviation of normal group's NRS was $5.11{\pm}1.69$ and high risk group's was $4.86{\pm}2.08$(P=0.504). Comparison between admission and discharge, standard deviation of normal group's NRS was $5.11{\pm}1.69$ and high risk group's was $4.86{\pm}2.08$(P=0.504) Conclusion : Low back patients with high Brachialankle Pulse Wave Velocity, showed slower improvement rate compare to patients within normal rate. But statically, had no significance.

도시기반 라이프라인은 지진발생시 시설물의 붕괴뿐만 아니라 붕괴로 인한 도시기능 마비, 대형화재와 같은 2차 피해를 동반하여 막대한 사회 경제적 손실을 야기할 것으로 예측된다. 이에 대한 대비책으로 국내에서는 지진재해대응시스템을 운영 중이며, 지진재해대응시스템은 각 시설물별 지진취약도 모델을 통해서 시설물의 파괴확률을 산정하고, 지진재해 정도를 평가한다. 따라서 본 논문에서는 국내 지반특성을 고려하여 도시기반 라이프라인 시설물 중 매설가스배관의 시간이력 해석을 수행하였고, 확률론적인 해석방법인 최우도추정법을 이용하여 지진취약도 모델을 개발하였다. 해석모델은 국내 대표도시인 서울지역에 매설된 고압관과 중압관으로 선정하였으며, 지반의 모델링은 Winkler foundation 모델을 이용하였다. 또한 개발된 취약도 모델의 GIS 적용방안을 제시하였다. City-based Lifeline is expected to cause significant social and economic loss accompanied the secondary damage such as paralysis of urban functions and a large fire as well as the collapse caused by earthquake. Earthquake Disaster Response System of Korea is being operated with preparation, calculates the probability of failure of the facility through Seismic Fragility Model and evaluates the degree of earthquake disaster. In this paper, the time history analysis of buried gas pipeline in city-based lifeline was performed with consideration for ground characteristics and also seismic fragility model was developed by maximum likelihood estimation method. Analysis model was selected as the high-pressure pipe and the normal-pressure pipe buried in the city of Seoul, Korea's representative, modeling of soil was used for Winkler foundation model. Also, method to apply developed fragility model at GIS is presented.
