Going back to long chinese medical history, there were many different methods of treatment according to the origin of local chinese areas, such as Bian-Shi(?石) from east, herbal therapy from west, acupuncturing from south, moxibustion from north, and mainpulating therapy from middle china. In the midst of these therapies, acupuncture needling had developed very much both in theories, shapes, usages and also in theraputic boundray. Historical books dealing with acupuncture had introduced and used Jiu-Zhen as a tool for acupuncture needling in common. But there are some differences between each texts about in shape, use, and there are also another different point of view about the interrelationship between Bian-Shi and Ji-Zhen. So the author, in this research, tried to look for how Jiu-Zhen had took on its real kinds, adaptive usages, theraputic boundaries, many different skills of needing. By researching over ${\ulcorner}$ Ling-Shu, Jiu-Zhen(靈樞,九鍼)${\lrcorner}$, ${\ulcorner}$ Ling-Shu, Jiu-Zhen-Shi- Yi-Yuan(靈樞,九鍼十二原)${\lrcorner}$, ${\ulcorner}$ Ling-Shu, Guan-Zhen(靈樞,官鍼)${\lrcorner}$, and by compar- ing them with the contents of Jiu-Zhen in ${\ulcorner}$ Zhen-Jiu-Yi-Jing(鍼灸甲乙經)${\lrcorner}$ ${\ulcorner}$Zhen-Jiu-Da-Cheng (鍼灸大成)${\lrcorner}$, the author discovered small conclusions such as following. 1. Taking Jiu-Zhen in a narrow sense, it only repesents nine different needle used in different cases. But in large sense, this means nine different deedling methods using each different needles which is represented in the form of Wu-Ci ( 五剌 ), Shi-Yi-Ci ( 十二剌 ) in ${\ulcorner}$ Ling-Shu, Guan-Zhen ${\lrcorner}$ 2. Jin-Zhen has been first originated from stone age as a substitute for Bian-Shi and through bronze and iron age, it followed a process of it's own shape and applicating functions. As an example, the moxibustional therapies shown in ${\ulcorner}$ Zu-Bi-Shi-Yi-Mai- Jiu-Jing ( 足臂十一脈灸經 )${\lrcorner}$ ${\ulcorner}$ Yin-Yang-Shi-Yi-Mai-Jiu-Jing ( 陰陽十一脈灸經)${\lrcorner}$ in ahead of ${\ulcorner}$ Nei-Jing ( 內經 )${\lrcorner}$ era, was relationship in acupuncturing skills and shape. So Jiu-Zhen had been originated on the base of Bian-Shi in ancient times to develop into delicate shape, skill, and theraputic foundation of modern oriental medicine.

This article is for considering and looking through the meaning of Classic of Poetry(Shi jing) Hiku-ka of Kobayashi Issa before reviewing and adapting Classic of Poetry(Shi jing) in Eastern Asia. Issa wrote his works by using Hyanghwa-Gucheop in 1803, and he had adopted it as his creative works of Hikai absorbing Classic of Poetry(Shi jing) for about half a year. There has been no national study about this so far, and this study covered the aspects of Issa's adapting way of Classic of Poetry(Shi jing) in Japan and China. There have been several problems that the contents were limited to Guo-feng and there were no agreement of terminology as well among researchers. To overcome these limitations, therefore, this article aimed at all the works, rejected the view point as just a translation, and denominated this study as Haiku-ka. Above all, this study looked though Issa's Classic of Poetry(Shi jing) by splitting the aspects of Haiku-ka into borrowing topics and materials. In borrowing topics, the works with the topics of homesick and nostalgic parents stood out. Furthermore, annotations and understandings of Issa's original works were deeply involved. In borrowing materials, the original meanings in the works were transformed and changed or even reinterpreted by their own way. Eliminating sublime emotions, furious tone, and condemnation was main characteristic of Haiku-ka in Classic of Poetry(Shi jing). Besides, there were ways of exclusion of reasoning, deviating from the viewpoint of Sigyo(edification by poetry), not including moral senses. In other words, Issa used habits and impressions like the way of Haiku when he was doing Haiku-ka in Classic of Poetry(Shi jing). The meaning that Issa's Hiku-ka of Classic of Poetry(Shi jing) stood out compared to adaptation of Classic of Poetry(Shi jing) in Eastern Asia. Although Classic of Poetry(Shi jing) in Vietnam was transferred in the form of the poem in Vernacular, the meaning and contents were not changed. Moreover, the original works and characters in Joseon were not destroyed because Classic of Poetry(Shi jing) was not liberally translated but literally. However, Issa transferred the Classic of Poetry(Shi jing) in the form of the poem in Vernacular to reveal the value of popular ballads. This was a different adapting way of Classic of Poetry(Shi jing) from that in Eastern Asia.

In this study, feature point detection and displacement measurement performance depending on feature extraction algorithms were compared and analyzed according to environmental changes and target types in the feature point-based displacement measurement algorithm. A three-story frame structure was designed for performance evaluation, and the displacement response of the structure was digitized into FHD (1920×1080) resolution. For performance analysis, the initial measurement distance was set to 10m, and increased up to 40m with an increment of 10m. During the experiments, illuminance was fixed to 450lux or 120lux. The artificial and natural targets mounted on the structure were set as regions of interest and used for feature point detection. Various feature detection algorithms were implemented for performance comparisons. As a result of the feature point detection performance analysis, the Shi-Tomasi corner and KAZE algorithm were found that they were robust to the target type, illuminance change, and increase in measurement distance. The displacement measurement accuracy using those two algorithms was also the highest. However, when using natural targets, the displacement measurement accuracy is lower than that of artificial targets. This indicated the limitation in extracting feature points as the resolution of the natural target decreased as the measurement distance increased.

In this paper we propose a feature point tracking algorithm using optical flow under non-prior taming active feature model (NPT-AFM). The proposed algorithm mainly focuses on analysis non-rigid objects[1], and provides real-time, robust tracking by NPT-AFM. NPT-AFM algorithm can be divided into two steps: (i) localization of an object-of-interest and (ii) prediction and correction of the object position by utilizing the inter-frame information. The localization step was realized by using a modified Shi-Tomasi's feature tracking algoriam[2] after motion-based segmentation. In the prediction-correction step, given feature points are continuously tracked by using optical flow method[3] and if a feature point cannot be properly tracked, temporal and spatial prediction schemes can be employed for that point until it becomes uncovered again. Feature points inside an object are estimated instead of its shape boundary, and are updated an element of the training set for AFH Experimental results, show that the proposed NPT-AFM-based algerian can robustly track non-rigid objects in real-time.

We have proposed a maximum power point tracking (MPPT) circuit for thermoelectric generator (TEG) using a Boost converter. The key point of the proposed MPPT circuit is that the duty ratio of the boost converter automatically moves to Maximum Power Point by comparing of consecutive sampling voltage using two comparators. From the simulation results, we showed that the proposed circuit can find the maximum power point within 2 CLK periods and to generate optimal PWM signal within 3 CLK periods. The proposed MPPT circuit was designed by using a CMOS 0.18 um process, and it is now on the fabrication.

The mission life of a satellite determines the amount of fuel required on-board, while the total mass requirement limits the fuel to be loaded. Hence, for the design of thruster control loop, not only the satellite pointing accuracy but the saving of fuel is to be considered. In this paper, a two-step fuzzy controller is proposed for the thruster control loop to save fuel consumption. This approach combines requirements for pointing control accuracy with minimum fuel consumption into a fuzzy controller design. To demonstrate this approach, we have designed a fuzzy controller for the Sun point Mode of KOMPSAT-2. The performance of this fuzzy controller design is compared with that of PD controller used for KOMPSAT-2.

Objectives : To introduce a rare case of a patient with Progressive Bulbar Palsy (PBP) and suggest the possibility of treatment using electroacupuncture and Korean Medicine. Methods : A 61-year-old man with PBP, complaining of dysarthria, was treated with electroacupuncture and Korean Medicine, from June 16 to July 10, 2015. Improvements in symptoms were measured using the speech mechanism screening test (SMST), measurement of tongue and orbicularis oris motility, and speech handicap index (SHI). Results : The scores of SMST, motility of tongue and orbicularis oris showed a tendency for gradual improvement with 25 days of Korean Medicine Treatment after admission, but conversation was still impossible. In SHI scores, one point increased in the speech domain and one point decreased in the psycho-social domain, and three points increased in the other domain. Conclusion : Electroacupuncture and Korean Medicine Treatment improved dysarthria caused by PBP, but not completely. Korean Medicine Treatment seems effective in the management of accompanying symptoms such as black hairy tongue, dry mouth, and general condition. The symptoms of PBP are similar to those of amyotrophic lateral sclerosis and there is controversy regarding the classification of PBP. The most important aspect of treating a patient with PBP is an early diagnosis and devising appropriate rehabilitation strategies.

A four-point bending RC beam strengthened with FRP plate is investigated based on the theory of elasticity. Taking the adhesive layer into account but ignoring some secondary parameters, the analytical solutions of the normal stress and shear stress on concrete-adhesive interface are obtained and discussed. Besides, the pure bending region of the beam is analyzed and the ultimate load of the beam is predicted. The results obtained in the present paper agree very well with both the results of FEM and the experimental findings.

The point load test (PLT) is a widely-used alternative method in the field to determine the uniaxial compressive strength due to its simple testing machine and procedure. The point load test index can estimate the uniaxial compressive strength through conversion factors based on the rock types. However, the mechanism correlating these two parameters and the influence of the mechanical properties on PLT results are still not well understood. This study proposed a theoretical model to understand the mechanism of PLT serving as an alternative to the UCS test based on laboratory observation and literature survey. This model found that the point load test is a self-confined compression test. There is a compressive ellipsoid near the loading axis, whose dilation forms a tensile ring that provides confinement on this ellipsoid. The peak load of a point load test is linearly positive correlated to the tensile strength and negatively correlated to the Poisson ratio. The model was then verified using numerical and experimental approaches. In numerical verification, the PLT discs were simulated using flat-joint BPM of PFC3D to model the force distribution, crack propagation and BPM properties' effect with calibrated micro-parameters from laboratory UCS test and point load test of Berea sandstones. It further verified the mechanism experimentally by conducting a uniaxial compressive test, Brazilian test, and point load test on four different rocks. The findings from this study can explain the mechanism and improve the understanding of point load in determining uniaxial compressive strength.
