Objective : This case report show the effect of Dahuanghuanglianxiexin-tang on VulvoVaginal Candidiasis. Methods : According to disease pattern identification diagnostic system based on shanghanlun provisions, The author diagnosed Taeyang-byung kyeolhyung. The symptoms of VulvoVaginal Candidiasis were worsen when the patient had long sitting position and digestive problems. Therefore the patient treated with Dahuanghuanglianxiexin-tang for 3 months. The severity of Candida Vaginitis was evaluated by patient's subjective statements(Vaginal pruritus, Vaginal secretion, Burning sensation). Results : After the treatment, Level of syptoms decreased from Severe to Trace and Eliminated. Conclusions : Dahuanghuanglianxiexin-tang improved the symptoms of VulvoVaginal Candidiasis on this study. Although Dahuanghuanglianxiexin-tang is not an usual treatment for VulvoVaginal Candidiasis, the author could prescribe the medicine due to shanghanlun six meridian patterns diagnostic system.

In order to produce the bacteriolytic enzyme, bacterial strains capable of excreting a large amount of the enzyme were screened from the coastal sea water samples in Pusan. The bacterial strain SH-1, which showed the highest activity among 43 bacteriolytic enzyme producing bacteria, was finally selected for further studies. The strain SH-1 was an endospore-forming grampositive rod, and the position of spore was paracentral. These morphological characteristics assigned the isolated strain to the morphological group I classified by Gordon. The fatty acid composition of the bacterial stain was analyzed to be consisted of branched chains of iso-Cn and anteiso-Cn. Based on the percent content of the branched chain (93.85%), the isolates could be identified as a species of Bacillus. According to the experimental results of the API system (API 50CHB & API 20E) the strain was identified as Bacillus subtilis. Numerical texonomy, in which 82 major characters were examined using several species of Bacillus as the standard bacteria, indicated that the strain SH-1 showed 90% similarity to Bacillus subtilis. Thus, the isolated strain SH-1 could be identified as Bacillus subtilis.

Grey-level statistical models have been widely used in many applications for object location and identification. However, conventional models yield some problems in model refinement when training images are not properly aligned, and have difficulties for real-time recognition of arbitrarily rotated models. This paper presents improved grey-level statistical models that align training images using image or feature matching to overcome problems in model refinement of conventional models, and that enable real-time recognition of arbitrarily rotated objects using efficient hierarchical search methods. Edges or features extracted from a mean training image are used for accurate alignment of models in the search image. On the aligned position and orientation, fitness measure based on grey-level statistical models is computed for object recognition. It is demonstrated in various experiments in PCB inspection that proposed methods are superior to conventional methods in recognition accuracy and speed.

We attempted to replace a benzopyran ring of 4-[(N-imidazol-2-ylmethyl)-4-chloroanilino]benzopyran, previously discovered as anti-angiogenic agent with antitumor activity, with pyranopyridines. The [3,2-c]-, [3,2-b]-, [2,3-c]-, and [2,3-b]-pyranopyridines with -(imidazol-2-ylmethyl)aniline moiety at the 4-position, were synthesized respectively, and evaluated for primary anti-angiogenic properties through primary cultured HUVEC tube formation assay. From this study, we found that the pyranopyridine ring, especially [3,2-b]- and [2,3-c]-isomer, can replace the benzopyran ring of the compound 1 and can be optimized through the introduction of substituents both on the pyranopyridine ring and the aniline moiety for the identification of a novel anti-angiogenic agent.

This paper represents the study of an effective self-tuning PID control for a robot manipulator to track a reference trajectory in spite of the presence of nonlinearities and parameters uncertainties in robot dynamic models. In this control scheme, an error model of the manipulator is established, for the first time, by difference between joint reference trajectory and tracked trajectory. It's model Parameters are estimated by the recursive least-square identification algorithm, and classical controller parameters are determined by pole placement method. A computer simulation study was conducted to demonstrate performance of the proposed self-tuning PID control in joint-based coordinates for a robot with payload.

In this paper, we utilize the CMG's momentum bias to control the roll/pitch attitude of the Quad-rotor. While the previous control approaches have used the thrust control approach, we design and add a new momentum controller (using CMG) in order to improve the transient response over the existing methods. The focal point of this paper is the design of a controller for a Quad-rotor's attitude using CMG. This leads to other tasks such as an identification of the model's parameters and mathematical nonlinear modeling. Then, the previous thrust controller is designed based on the linearized model. Finally, the overall system with our designed controller is implemented and tested in real time to show that the Quad-rotor is kept in a good balanced position faster than the traditional thrust-only control approach.

An algorithm of 3-D particle image velocimetry(3D-PIV) was developed for the measurement of 3-D velocity field of complex flows. The measurement system consists of two or three CCD camera and one RGB image grabber. In this study, stereo photogrammetty was applied for the 3-D matching of tracer particles. Epipolar line was used to decect the stereo pair. 3-D CFD data was used to estimate algorithm. 3-D position data of the first frame and the second frame was used to find velocity vector. Continuity equation was applied to extract error vector. The algorithm result involved error vecotor of about 0.13 %. In Pentium III 450MHz processor, the calculation time of cross-correlation for 1500 particles needed about 1 minute.

This paper describes the development and control of a quadruped walking robot, named as KAISER-II. The control system with multiprocessor based hierachical structure is developed. In order to navigate autonomously on a rough terrain, an identification algorithm for robot's position is proposed using 3-D vision and guide-mark pattern Also, a simple attitude control algorithm is included using force sensors. Through experimental results, it is shown that the robot can not only walk statically on even terrain but also cross over or go through the artificially made obstacles such as stairs, horizontal bar and tunnel-typed one.

The purpose of this study is to help domestic aquaculture farm by improved evaluation method. First, We analyzed evaluation method of domestic aquaculture certification, the greater retailer's supplier and global standard. Next, By using Analytic Hierarchy Process (AHP), We found priority and importance between criteria of SQF(Safety Quality Food) standard which is appled to alternative model for aquaculture evaluation. As a result is presented as follows: regarding pairwise comparison between System Element module and Good Aquaculture Practice(GAP) module, GAP is recognized to be more important than System Element. The highest priority criteria is presented 'Purchase and Use of Medications, Aquaculture Feeds and Aquaculture Chemicals.' Next, 'Management commitment', 'Attaining Food Safety', 'Location and Layout of Structures and Vessels', 'Stock Identification and Traceability are recognized high position. This study has major implications for research into development of evaluation method.

This paper is concerned with the forced flexural vibration analysis of hard disk drive (HDD) spindle systems with multiple thin disks, supported by two ball bearings based on the finite element model. This is the extension of the previous work which analytically modeled every system component taking into account its structural flexibility and also the centrifugal stiffening effect especially for the disks. Among the end results, the forced time response is expectedly useful for the vibration control of the spindle itself or the position servo control of the magnetic head. On the other hand, the steady state responses such as the frequency response function and the unbalance response are useful for system identification. Futhermore, through a coordinate transformation the equations of motion is also derived with respect to the inertial frame for convenient analyses of certain classes.
