Objectives : The aim of this study is to develop the system and evaluate the optical analytical technique that reflects acupoint pigmentation and extravasated blood by cupping. Methods : We designed the system able to express XYZ coordinate on local skin color. To evaluate measurement-accuracy, we compared with 24 Color Checker Chart by standardized Commission Internationale de l``Eclairage. After confirming the performance of system, we experimented with cupping which was 80 kPa negative pressure for 1 minute on left/right BL13. The X, Y and Z values were converted to R, G and B, L*, a* and b*, Erythema Index (E.I.), and Melanin Index (M.I). We compared and analyzed two cases on before/after cupping. Results : The R, G and B values which were converted by X, Y and Z values had high linearity as a high level of R-square (R: 0.969, G: 0.996, and B: 0.992). Moreover, we confirmed that it was possible to quantitatively analyzed the change in skin color by cupping using R, G, B, L*, a*, b*, E.I., and M.I. Conclusions : Therefore, we proposed the new analytical technique for objectifying the oriental medical diagnostic method using cupping and optical sensing technique.

부항요법은 다양한 질환에 치료목적으로 널리 사용되어 왔다. 그러나 부항에 대한 경락과 경혈의 상태 변화에 관한 연구가 전무한 상태이다. 본 연구에서는 부항자극에 대한 경락경혈의 상태변화를 분석하여 인체 전체에 미치는 파급효과를 확인하고자하였다. 이에 일정 음압(30kPa)으로 자극 가능한 시스템을 개발하였으며, 좌측 수태음폐경(LU)의 협백(LU4)과 척택(LU5)의 경락선상 중간지점을 자극하였다. 좌/우 수태음폐경의 경혈 및 비경혈에서 수분, 탄성도를 측정하였으며 상완이두박근에서 EMG 신호를 자극 전/후 측정하여 부항 요법이 인체에 미치는 영향을 관찰하였다. 그 결과, 자극 전/후 수분의 변화는 12.49%로 미비하였으며, 탄성도는 64.42%로 높은 변화를 확인하였다. 또한, 경혈이 비경혈 보다 탄성도 변화가 많았으며, 좌측보다 우측에서의 탄성도 변화가 많이 관찰되었다. 좌/우 EMG 신호의 RMS와 Median Power가 유의하게 낮아졌으나 Median frequency에서는 유의성을 확인할 수 없었다. 따라서, 음압자극은 경락경혈의 탄성도 및 근전도 변화를 유도함으로써 인체 전체에 파급적 효과를 줄 수 있음을 확인하였다. Cupping therapy has been used to extensive diseases. However, the research was yet to meridian and acupoint's change of state caused by Cupping. This study was considered a human-ripple effect by the anlaysis of meridian & acupoint's change of state. We developed the system which is keeps 30kPa Negative-pressure and stimulated on the Left Lung Meridian(LU) a halfway point between LU4 and LU5. We checked moisture and elasticity change on left/right acupoints & non-acupoints, then measured EMG Signal. We observed that moisture had little change(12.49%) and the better part of the elasticity on both sides had identified the change(64.42%). The number of the provoked acupoiunt elasticity change was more than non-acupoint. Also, elasticity change of Right side was more than Left side. We confirmed that RMS and Median Power change patterns were lower in proportional to the elastin change, but there was no significance about Median Frequency. Therefore inducing the change of elasticity and EMG signal on meridian-acupoints. Therefore, We checked the human-ripple effect Negative-pressure by the Cupping therapy.

This study is aimed to develop 150W LED street light using mirror optical system to improve existing LED street lights which have glaring effects and do not have luminous intensity uniformity. This paper attempts to solve to use the aspheric technology with different concept. To removing glaring and improve luminous Intensity uniformity, we implemented optical design with suitable structure and aspheric data by using an optical program. We analyzed results by using a lie s simulation program before making prototype. After making LED lights through these analysises, conclusion was made that reflectivity of reflector has great influence.

This study is aimed to make better environment with less bacteria by drying various sort of towels. This dryer is made with nano surface heater which is more eco-friendly and lower energy consuming than previous dryers. Also it is long-lived and dose not need that much repairs by reason of simpleness, and durability.
