A novel controller design is presented for the recently proposed electric springs (ESs). The dynamic modeling is analyzed first, and the initial Bode diagram is derived from the s-domain transfer function in the open loop. The design objective is set according to the characteristics of a minimum phase system. Step-by-step optimizations of the Bode diagram are provided to illustrate the proposed controller, the design of which is different from the classical multistage leading/lagging design. The final controller is the accumulation of the transfer function at each step. With the controller and the recently proposed δ control, the critical load voltage can be regulated to follow the desired waveform precisely while the fluctuations and distortions of the input voltage are passed to the non-critical loads. Frequency responses at any point can be modified in the Bode diagram. The results of the modeling and controller design are validated via simulations. Hardware and software designs are provided. A digital phase locked loop is realized with the platform of a digital signal processor. The effectiveness of the proposed control is also validated by experimental results.

The Meridian and Collateral Diagram is one of the most important 圖像s of Traditional Korean Medicine. A 圖像 is a picture made on a two-dimensional surface using lines and colors to portray an object or an image. Meridian and Collateral diagram is a 圖像 of the human body with indications of acupoints and meridian passageways and have different names such as 經穴圖, 輸穴圖, 鍼灸圖, 明堂圖, 銅人圖, in accordance with its classification. The documental basis of the Meridian and Collateral Diagram is the Internal Classic and the very first Meridian and Collateral Diagram confirmed through textual evidence can be found in 葛洪's "抱朴子 雜應". The Korean 동인도 in existence today, called '銅人明堂之圖', exists in two versions; a hand-copied version and a wooden engraving block version. It displays all the locations of the acupoints located on the anterior side of the human body, labels the names of the acupoints, and specifically distinguishes 起始穴 and 終止穴 of the eight meridian vessels.

The following conclusions are drawn from a review on the theory of correlation between the jang-bu organs in 'Ojangchunchaklon(五臟穿鑿論)' which is quoted in 'Uihakipmoon(醫學入門)' and 'Donguibogam(東醫寶鑑)'. The three yangs and three yins are trisections each of yang ki and y1n ki. They represent three aspects of change in powers of yin ki and yang ki. The theory of Kaehapchu(開闔樞 the opening, closing and pivot) is thought to be the concept which explains the three states of jang-bu organs and meridians in terms of three yangs and three yins. The three yangs and three yins are assigned to twelve months according to the generation, prosperity and vanishment of the water, the fire, the wood and the metal in the circulation of nature with the lapse of time. Most of all, the change of the water and the fire is the main guide to the assignment. Both the theory of exterior-interior relations in jang-bu organs and meridians and the theory of Kaehapchu are founded on the assignment of three yangs and three yins to twelve months. The correlation between jang-bu organs is based on the monthly assignment of three yangs and three yins described in 'Internal classic(內經)' and the theory of Kaehapchu. In the correlations between jang-bu organs and meridians, the exterior-interior relations are the correspondences of Hand to Hand and Foot to Foot. but the relations of Kaehapchu are those of Hand to Foot and Foot to Hand. Jeesan's diagram of pulse is grounded on the correlations between jang-bu organs. On the left of the diagram, jang organs are arranged in the order of hierarchic positions in body. On the right, bu organs are disposed according to the correlations with the jang organs. Jeesan's diagram includes the principles of triple harmony and diagonal groups in twelve earthly branches(十二支). Jeesan's diagram is the frame through which correlations of jung-ki-shin-hyul, five jang and six bu organs, twelve meridians and six intrinsic factors can be observed at once.

In this study, to confirm the effects of the mixed load of normal and shear forces acting on a fixing bolt, fatigue design criteria were developed by varying the loading angle and conducting tensile and fatigue tests. After evaluating and comparing the test results under different loading angles, the evaluation criteria were selected. These evaluation criteria were then applied to develop the design criteria. An Arcan fixture was designed and manufactured to simultaneously apply a mixed load of normal and shear forces to the fixing bolt of a turntable, and a fatigue test was conducted. S-N diagrams for various loading angles were obtained, and a 1% P-S-N diagram of failure probability was determined using statistical processing techniques. Our results show that failures of the fixing bolt can be prevented using these diagrams as a basis for developing fatigue design criteria.

Objectives : To clarify the construction, changes, and contents of the diagrams of spleen through comparison of 30 different diagrams originated from Mingtangzangfutu. Methods : The diagrams were analyzed in whole shape, ratio between width and height, shape of the lower part, and concavo-convex of the middle part, then matched to the characteristics of the section diagram. The contents of the diagram of the spleen were newly interpreted with comparison to the classical texts. Results : The whole shape is described to be a long sword, long stick, bottle gourd, western pear, sole of feet. The height to width ratio was mostly above 4.0:1, but those listed in the 『Bianquemaishunaning』 and 『Hehensancaituhui』 were 1.9:1~1.0:1, most similar to the numbers described in the 『Nanjing』. The shape of the lower part was narrow and sharp, narrow and flat or wide and flat. To analyze through affiliation characteristic, properties of other affiliations could be found. In comparison to classical texts, the diagrams could be found to be affected by 『Nanjing』 and Wangbing's annotations. The diagrams of the spleen should be composed of the spleen, the cord of spleen, and Sangao(散膏); but those which distinguish the spleen and the cord of spleen are twelve. The description of its shape as being similar to sword or sickle seems to come from Lichan's misunderstanding of the diagram in 『Zhenjiujuying』. Those that mention Sangao are merely two and their opinion on the position are different from each other; both did not identify it with the pancreas. Conclusions : In the process of the diagrams differentiating into 30 they were affected by the classical texts. The various changes seem to come from difference in understanding of the content composition of the diagram of the spleen.

The objectives of this study are to investigate the prevalence of occupation related carpal tunnel syndrome(CTS) among workers in a condom industry : to analyse the sensitivity and specificity of clinical signs or symptoms such as hand diagram, Tinel's sign and Phalen's sign in carpal tunnel syndrome : and to test vibration threshold test using audiometry as a technically easy and noninvasive method in the diagnosis of carpal tunnel syndrome in stead of nerve conduction velocity (NCV). The study group was divided into exposed group(39 cases) and non-exposed group(48 cases) based on whether or not excessive use of wrist movements exsist. 1. There are stastically significant differences in symptoms and signs of carpal tunnel syndrome such as hand diagram, Tinel's sign and Phalen's sign between exposed and non-exposed group(p<0.05). 2. Six cases(9 hands) were comfirmed as carpal tunnel syndrome by NCV. Five cases(7 hands) belonged to exposed group, 1 case(2 hands) to nonexposed group. As there are significant differences in prevalence of carpal tunnel syndrome between two groups(p<0.05), excessive use of wrist in occupation is a risk factor of carpal tunnel syndrome. 3. When we use NCV as a gold standard in the diagnosis of carpal tunnel syndrome, sensitivity and specificity of hand diagram, Tinel's sign and Phalen's sign is as followed; hand diagram , sensitivity 88.9%, specificity 84.2% Tinel's sign ; sensitivity 55.6%, specificity 72.8% Phalen's sign ; sensitivity 14.3%, specificity 88.4%. Among above clinical signs and symptoms, hand diagram is the best clinical screening test. 4. The differences of vibration threshold between median and ulnar nerve at the same time are useful in the diagnosis of carpal tunnel syndrome but the time change of vibration threshold of median nerve over time are not sensitive enough. It is concluded that vibration threshold between median and ulnar nerve at the same time can be used as a supplementary or alternative criterion to indicate that the nerve dysfunction is located in the carpal tunnel.

We present an efficient algorithm for finding the sequence of extreme vortices of a moving regular convex polyhedron of with respect to a fixed plane H.. The algorithm utilizes the spherical Voronoi diagram that results from the outward unit normal vectors nF$_{i}$ 's of faces of P. It is well-known that the Voronoi diagram of n sites in the plane can be computed in 0(nlogn) time, and this bound is optimal. However. exploiting the convexity of P, we are able to construct the spherical Voronoi diagram of nF$_{i}$ ,'s in O(n) time. Using the spherical Voronoi diagram, we show that an extreme vertex problem can be transformed to a spherical point location problem. The extreme vertex problem can be solved in O(logn) time after O(n) time and space preprocessing. Moreover, the sequence of extreme vertices of a moving regular convex polyhedron with respect to H can be found in (equation omitted) time, where m$^{j}$ $_{k}$ (1$\leq$j$\leq$s) is the number of edges of a spherical Voronoi region sreg(equation omitted) such that (equation omitted) gives one or more extreme vertices.
