Forty four patients with Bell's palsy were treated with acupuncture from onset and clinical observation was carried on from March 1994 through Feburary 1995. Acupuncture treatment was done 3 times per week and the acupuncture points were LI4 Hapkok, ST36 Choksamni, LI20 Yonghyang, BL2 Ch'anjuk, TE17 Yep'ung, ST4 Chich'ang, ST6 Hyopko, GV26 Sugu, CV24 Sungjang, GB14 Yangbaek and Ex-HN4 Oyo. They were inserted to a depth of 0.5 to 1.0 cm. After insertion, manipulation was carried on until the patients felt strong numbness or De Qi sensation induced by rotating or twisting needles. Through-needling in lengths varying from 2.0 to 3.5 cm was also applied from ST4 Chich'ang to ST6 Hyopko, from GV26 Sugu or CV24 Sungjang to ST4 Chich'ang and from GB14 Yangbaek to Ex-HN4 Oyo. The mean age was 39.3 and 63.6% of the patients were women, including one pregnant woman. There was no recurrent palsy in this study. By applying the House-Brackmann facial nerve grading scales, patients were evaluated weekly from the first treatment to judged recovery or the 7th week of the treatment. 86.4% of the patients were recovered completely within 7 weeks and the average healing period was 3.7 weeks.

Front Points are told to be deeply related with viscera and bowels in oriental medicine. Since the Front Points are treated as response zone, it can be used for the diagnosis and treatment of disease in viscera and bowels. The location of Front Points are very similar to the several response zones in western medicine. Diagnostic aspect of Front Points to several response zones were discussed in here based on many thesis and reported laboratorial experiments. Front Points are located in the same latitude of viscera and bowels. So, diagnosis result in Front Points represent condition of each organs. Palpitation of the Front Points can make diagnosis of body surface and the organ beneath the body surface. Such use of Front Points for diagnosis can used as the treatment points also. Only three Front Points (LU-1, LI-14, GB-24) in lung, liver and gall bladder meridian are located on its meridian. The Front Points of Stomach (CV-12) cross its meridian or closely located to it. Unlike to those four Front Points that are matched to its meridian, other eight Front Points do not located or cross its meridian at all. It seems that the location of Front Points are decided by the location of organs and the conditions at a certain organ do not delivered by the meridians but delivered by main collaterals, tertiary collaterals and superficial collaterals instead. Among visceral response zones, Five Front Points (CV-3, CV-4, CV-12, LI-14, GB-25) are exactly matched to Head's response zone and other Front Points are closely matched to the Head's response zone. There are five Front Points (CV-12, CV-14, CV-17, LI-14, GB-24) that are matched with the location of pressing palpitation point and other Front Points are closely located to the pressing palpitation point. So far, it was clear that the Front Points do have important role as response points. Symptoms expressed to the Front Points were delivered conditions or symptoms occur in corresponding organ and the anatomical location of Front Points were also found near the corresponding organ. Diagnostic and therapeutic application of Front Points for Organ theory and in the Interpromotion-restraint of the five elements in oriental medicine can be made in future to increase its potential.

The aim of this study is to collect and analyze clinical studies on acupuncture therapies of Post-stroke depression, and to suggest a method on study about acupuncture therapies. In this thesis, electronic searches were performed. Also, 6 major journals associated with oriental medicine in Korea were searched manually. Through searching, 27 studies were selected and analyzed. There were 24 controlled studies and 3 non-controlled studies. Treatment methods were acupuncture, electronic-acupuncture, eye-acupuncture, abdominal-acupuncture and pharmaco-puncture. The percentages of these treatment method were 59.2%, 29.6%, 3.7%, 3.7% and 3.7%, respectively. Acupuncture points such as GV20, PC6, ST36, SP6, LV3, GV24, GV26, LI14, LI11, H7, ST40, GB20, GB34 and LI15 were used. In comparison of results before and after acupuncture treatment, there were statistically significant improvement in 26 studies. Based on the results from above, the studies on acupuncture for Post-stroke depression needs to be standardized and more appropriate high-quality study models should be introduced.

Mid-span spectral inversion (MSSI) has to utilize high optical pump power, for its operation principle is based on a nonlinear optical wavelength conversion. In this paper, a low pump-power operation of MSSI-based chromatic dispersion compensation (CDC) has been achieved successfully, for the first time to our knowledge, by introducing a noise pre-reduction scheme in cascaded wavelength conversions with periodically poled $LiNbO_3$ waveguides at a relatively low operation temperature. As preliminary studies, phase-matching properties and operation-temperature dependence of the wavelength converter (WC) were characterized. The WC pumped at 1549 nm exhibited a wide conversion bandwidth of 59 nm covering the entire C-band and a conversion efficiency of -23.6 dB at 11 dBm pump power. CDC experiments were implemented with 2.5 and 10 Gb/s transmission systems over 100 km single-mode fiber. Although it is well-known that the signal distortion due to chromatic dispersion is not critical at a 2.5 Gb/s transmission, the clear recovery of eye patterns was identified. At 10 Gb/s transmission experiments, eye patterns were retrieved distinctly from seriously distorted ones, and notable improvements in bit-error rates were acquired at a low pump power of 14 dBm.

Automated driving systems require a high level of performance regarding environmental perception, especially in urban environments. Today's on-board sensors such as radars or cameras do not reach a satisfying level of development from the point of view of robustness and availability. Thus, map data is often used as an additional data input to support these systems. An accurate digital map is used as a powerful additional sensor. In this paper, we propose a new approach for vehicle localization using a lane map and a single-layer LiDAR. The maps are created beforehand using a highly accurate DGPS and a single-layer LiDAR. A pose estimation of the vehicle was derived from an iterative closest point (ICP) match of LiDAR's intensity data to the lane map, and the estimated pose was used as an observation inside a Kalmanfilter framework. The achieved accuracy of the proposed localization algorithm is evaluated with a highly accurate DGPS to investigate the performance with respect to lateral vehicle control.

1) Objective External treatments have various curative effects. So it had been used to cure various patients. But, it has a limited sphere of application in the present South Korea. And the ${\ulcorner}$Li-Yao-Pian-Won${\lrcorner}$ had been written by Wu-Shang-Xian(吳尙先) in 1864. The book is the first technical book of external treatments. So, he has been held in respected as the father of external treatments by many people. Therefore we would like to bring out it’s external treatments theory 2) Conclusions Wu-Shang-Xian(吳尙先) had insisted that external treatments principles are identical with internal treatments. So, prescriptions of external treatment are selected and made by principles of internal treatment. (1) The factors of determination external treatment’s methods are focus (meridian, inside and outside etc.), attribute of diseases, patient’s liking. (2) The treatment regions are decided by meridian theory, diseases region and external treatment’s methods.

In growing single crystals, which exhibit incongruent melting behavor, it is extremely difficult to maintain the stoichiometry of its chemical compositions for given crystals. For instance, $LiNbO_3$ is a typical one which exhibits such incongruent melt, especially with a large solid solution region that makes it difficult to maintain the chemical compositions. Such a variation can then cause a serious problem for the practical applications in designing a precision electro /optic device. Of the known methods of determining its composition and quality, an optical technique of measuring refractive index of the crystals has been implemented. This technique is also capable of determining optical uniformity of the grown crystals and the chemical compositions. The technique used for such characterizations is herein described and some of results are discussed.

Li ion battery (LIB) is one of the most remarkable energy storage devices currently available in various applications. With a growing demand for high-performance batteries, the role of electrochemical analysis for batteries, especially, electrode reactions are becoming very important and crucial. Among various analytical methods, cyclic voltammetry (CV) is very versatile and widely used in many fields of electrochemistry. Through CV, it is possible to know electrochemical factors affecting the reaction voltage and reversibility, and furthermore, quantitative analysis on Li⁺ diffusivity as well as intercalation and capacitive reactions, and also anionic redox reaction. However, the explanation or interpretation of the results of CV is often deficient or controversial. In this mini-review, we briefly introduce the principle of cyclic voltammetry and its applications in LIB to bring a better understanding of the electrochemical reaction mechanisms involved in LIB.

The present study was performed to elucidate the therapeutic effect by aquapuncture with bee-venom (apitoxin) for treatment of canine pyoderma. The total 8 dogs with pyoderma were divided into 2 groups as control (antibiotics group: 4 dogs) and experimental groups (apitoxin group: 4 dogs). Antibiotics group was treated with bathing and antibiotics, while apitoxin group was treated with bathing and aquapuncture with apitoxin at Fei Shu (BL13), Wei Zhong (BL40), Da Zhui (GV14), Zu San Li (ST36), He Gu (LI04), Qu Chi (LI11), and San Yin Jiao (SP06). Based on the results of changes in clinical symptoms, total leukocyte counts, neutrophil/lymphocyte ratios and histopathological findings, antibiotics and apitoxin groups were all effective for treatment of canine pyoderma, and significant differences were not detected between the groups. It was suggested that apitoxin might be used as an alternative method to antibiotics for treatment of canine pyoderma.

This paper presents a tri-wideband bandpass filter (TWB-BPF) with compact size, high band-to-band isolation, and multiple transmission zeros (TZs). The proposed TWB-BPF is based on a multiple-mode resonator (MMR), which is interpreted by the method of the even- and odd-mode analysis technique. The MMR can excite 11 resonant modes, where the first two modes comprise the first passband, the next four modes form the second passband, and the last five modes are used to generate the third passband. In addition, 10 TZs are yielded to obtain high band-to-band isolation and wide stopband suppression characteristics up to $14.95f_{c1}$ ($f_{c1}$ is the center frequency of the first passband). To verify the proposed filter, a TWB-BPF with 3-dB fractional bandwidths (FBWs) of 37.4%, 43.5%, and 40.4% is designed, fabricated, and measured.
