Phototherapy has perpetual history. we can see an instance of it in Yellow Emperor's Canon of Medicine(黃帝內徑) and Laser therapy is a field of Phototherapy being used frequently in the latest time. We treated patients with hyperpigmentation by laser therapy and experimented it's efficacy and studied the means of clinical application in Korean medicine. We report the capabilities of application of laser therapy, based on the Korean medical theories by using resemblance between laser therapy with kyung-rak(經絡) control technique in the line that connects with the past.

It has been shown that bilateral decrease of point H4,5,6 in Ryodoraku test is related with gastric dysmotility. This suggested that the system of Kyung-Rak related with anatomical gastric disease may not be the Stomach Meridian, in the view that the system of Kyung-Rak is similar to that of Ryodoraku, and which was not consistent with classical contents of Kyung-Rak principle. Therefore, this paper was done to investigate whether bilateral decrease of point H4,5,6 is a general sign of common gastric disease in Ryodoraku test and to study its relation between Kyung-Rak principle and autonomic nervous system as a mediator explaining Ryodoraku response. As shown in the results of this study, different electrical response of Ryodoraku between patients with dyspepsia of gastric dysmotility and gastric ulcer revealed discrepancy of location indicating anatomical stomach between Kyung-Rak principle and Ryodoraku and instability of explanation of autonomic nerve theory to Ryodoraku. Thus, it presented the possibility that artificial application of Kyung-Rak principle against Ryodoraku may destroy its originality in the clinical field. To correctly use Ryodoraku in the diagnosis or evaluation of disease, Ryodoraku test should be used according to Nakatani's suggestion and clinical indication of which is limited to the diseases complicated with dysfunction of the autonomic nervous system.

Phototherapy have perpetual history, we can see an instance of it in Yellow Emperor's Conon of Medicine(黃帝內經) and Laser therapy is a field of Phototherapy being used frequently in the latest time. We treated patients with telangiectasia by laser therapy and experimented it's efficacy and studied the means of clinical application in Korean medicine. We report the capabilities of application of laser therapy, based on Korean medical theories by using resemblance between laser therapy with kyung-rak(經絡) control technique in the line that connects with the past.

According as we look around a notion of LM-YANG(陰陽) in NAE-KYUNG(內徑) or ancient for example the Book of Changes(周易), we will find that the principle of UM-YANG of philosophy in ancient china was applied medical science by NAE-KYUNG, and Chung-Kyung(仲景) connected principle of UM-YANG in NAE-KYUNG to demonstration and medical treatment(辨證施治) of SANG-HAN disease(傷寒病). According as we look around 3UM-3YANG(三陰三陽) in NAE-KYUNG and various theories of another scholar connected 3UM-3YANG of SANG-HAN-RON(傷寒論), we can know that the whole of SANG-HAN-YUK-KYUNG(傷寒六經) cannot explain by a some conception, we cannot understand precisely rear meaning of SANG-HAN-YUK-KYUNG until theories-JANG-BU(臟腑), GYUNG-RAK(經絡), GI-HWA(氣化), a reigon, a layer, and so on-are studied totally. Therefore 3UM-3YANG of SANG-HAN-RON(傷寒論) is basically the thing of specialization UM-YANG, eventually UM-YANG are two functional characteristics in human body. It is specialized to 3UM-3YANG by spatial and time criteria. When we consider a question in its aspect, YUK-KYUNG is synthetic six classifications of human body's functional system that include(3UM-3YANG)GYUNG-RAK, related JANG-BU, distributional area of GYUNG-RAK, vicissitude of UM-YANG, more or less of GEE-HYUL(氣血), function of GAE-HAB-CHUL(開闔樞), and the like; and disease of YUK-KYUNG of SANG-HAN-RON are the very six types of disease that appeared by dint of mal function of each synthetic functional system.

we present a pressure sensor based on the mechanically formed long-period fiber gratings. The attenuation properties of an output power as a function of an external pressure is able to apply to the in-line fiber pressure sensors for the vessels.

광통신이 발달하면서 보다 빠른 정보전송을 할 수 있지만 다른 전송매체와 마찬가지로 장거리 전송 시 손실이 발생하고 이러한 문제의 해결책으로 광 증폭기의 필요성이 대두 되었다. 기존의 광신호 증폭기에서는 광 신호를 전기신호 변환한 후 증폭하고 다시 증폭된 전기신호를 광신호로 변환하는 과정과 복잡한 구조는 전송시스템의 병목 문제를 유발하였다. 이러한 문제점을 해결할 수 있는 순수 광신호 증폭시스템인 어븀첨가광섬유증폭기 (EDFA)를 제작하고 EDFA의 이득평탄화를 위하여 이득평탄화 필터로 MLPFG를 제작하여 적용하였다. 제작된 EDFA는 20dB 이상의 신호 증폭을 보였다.

We have developed novel optical-fiber sensors based on strain-induced long-period fiber gratings for monitoring the deformation of a hull. They have no external pressure for sustaining the mechanical formed gratings. The pressure, which provides a force to form the periodic grating along the single mode fiber, was realized by the bonding strength of a photopolymer. To reduce the polarization dependency of the sensors caused by the asymmetry structure of gratings, a Faraday Rotator Mirror (FRM) was utilized in this experiment. We have realized the polarization-insensitive function of the proposed sensors. The change of an external strain are measured by an optical spectrum analyzer. When the external stain increases. the attenuation at the resonant wavelength decreases and the loss peak was slightly shifted to the shorter wavelength.
