Objectives : To discuss the therapeutic properties of Daoyin, and suggest ways to apply the Spleen Daoyin Method clinically. Methods : The therapeutic properties of Daoyin were examined in medical texts, after which the movements and effects of the Spleen Daoyin Method were analyzed. Based on relevant contents in the Donguibogam, symptoms and diseases for application of the Spleen Daoyin Method were studied to suggest further clinical application possibilities. Results & Conclusions : Daoyin manages the body by treating diseases, while keeping the Shen intact to manage the mind. In the case of the Five Zhang Daoyin Method, its therapeutic nature is clear as the target is focused on the Five Zhang. The Spleen Daoyin Method is mostly comprised of two movements that enable overall restoration and improvement of the Spleen function. Therefore, it could be applied in cases of Spleen-Stomach diseases where there is functional damage.

We propoes a study on the dynamic characteristics analysis and position control of 5-degree multi-joint manipulators for untact remote working at construction sites and manufacturing plants. The main frame of freedom multi-joint manipulator consists of five elements, boom cylinder, boom cylinder, arm cylinder, bucket cylinder, and rotation joint and link. In addition, the main purpose of the proposed system is to realize the work of the manufacturing process or construction site by remote control. Motion control of the entire system is a servo valve control method by hydraulic servo cylinders for one to four joints, and a servo motor control method is applied for five joints. The reliability of the proposed method was verified through performance experiments by computer simulation.

This study presents a genetic algorithm-based method for optimizing control parameters in fluid power systems. Genetic algorithms are general-purpose optimization methods based on natural evolution and genetics. A genetic algorithm seeks control parameters maximizing a measure that evaluates system performance. Five control gains of the PID-PD cascade controller fr an electrohydraulic speed control system with a variable displacement hydraulic motor are optimized using a genetic algorithm in the experiment. Optimized gains are confirmed by inspecting the fitness distribution which represents system performance in gain spaces. It is shown that optimization of the five gains by manual tuning should be a task of great difficulty and that a genetic algorithm is an efficient scheme giving economy of time and in labor in optimizing control parameters of fluid power systems.

Objectives: This paper was aim to report the clinical study for five cases received Korean medicine hospital treatment because of hysterectomy sequelae within 5 days after surgery.Methods: The patients having treated with hospital management, from March 1st in 2014 until March 24th in 2015, was enrolled in this study. We collected their age, chief complaint, vice complaint, diagnosis, visit days after surgery, treatment period, and etc. We treated the patients with acupuncture, moxibustion, and herbal medicine.Results: All of the cases treated with Korean medicine in this study revealed the recovery. The vice complaint also had improved.Conclusions: Korean medicine is effective on patients having variable postoperative symptoms following hysterectomy. And it is necessary to conduct an additional treatment about menopause symptoms.

The conventional and new forming processes of a steel shell body are analyzed by the rigid-plastic finite element method. The conventional process contains five forming stages such as bending, drawing, ironing, heading and sizing, which was designed by a forming equipment expert. The results of simulation of the conventional forming process are summarized in terms of deformation patterns and load-stroke relationships for each forming operation. Based on the simulation results of the current five-stage, the shell body forming Process including backward extrusion is designed for improving the conventional process sequence. Forming loads of the proposed process are within the limit value, which is proposed by experts and the proposed process is found to be proper for manufacturing steel shell body.

This paper presents an efficient 5-axis roughing method for centrifugal impeller. The efficient roughing is minimization of cutting time through minimizing tool tilting and rotating motions. To minimized cutting time, machining area is divided into sub-cutting regions using control points on hub curves and shroud curves of blade used to design and analyze centrifugal impeller. For sub-cutting regions, diameters of cutting tools are determined as big as possible. Then, tool paths are generated with the tilting axis and rotating axis of 5-axis machine limited and fixed, which can give more efficient machining speed and machining stability than the conventional methods. Experimental results show that the proposed method is more efficient than the conventional methods to mill with the only one cutting tool without dividing area and the previous methods to mill with simultaneous 5-axis processing with dividing area.

Objectives: This study reports the effects of HongYi (Formica yessensis) pharmacopuncture on the women voiding dysfunction patients. Methods: The women patients who complain of voiding dysfunction were treated with HongYi pharmacopuncture for ten times. We measured the international prostate symptom score (IPSS) for five times and analyzed. Results: After treatment with HongYi pharmacopuncture for ten times, the IPSS was improved in all of the patients. Complaints of voiding dysfunction was reduced and other symptoms also improved. Conclusions: HongYi pharmacopuncture is effective on women patients complaining of urinary disturbance.

In this study we developed monosyllable lists for articulation test for Korean. We sampled 103,581 colloquial monosyllables, applied them to five selection rules that based on Korean linguistic characteristics, and finally constructed five different lists with fifty monosyllables. The validity test using the monaural impairment factors such as S/N ratio and cut-off frequency showed that articulation scores were chanted systematically according to the level of impairment factors. In addition, we investigated the effect of azimuth of a single competing sound upon articulation scores. The syllables were always reproduced by the loudspeaker in front of the subject, while Hoth noise were reproduced by the loudspeaker with varying azimuth around subject. The result indicated that the articulation depended on the azimuth of competing sound sources. Finally, no significant differences among lists were found in all experimental conditions.

This study compares the maximum power point tracking (MPPT) control methods of a thermoelectric generator on vehicles. The researchers conduct comparisons on five different MPPT methods, including a fractional open circuit voltage method, a perturbation and observation (P&O) method, an incremental conductance method, a linear extrapolation-based MPPT (LEMPPT) method, and a LEMPPT/P&O hybrid method. These five MPPT methods are theoretically analyzed in detail, and the comparisons are conducted through MATLAB/Simulink simulation results. The comparison outcomes reveal that linear MPPT methods, including LEMPPT and LEMPPT/P&O hybrid methods, are more suitable for a thermoelectric generator on vehicles than the other MPPT methods examined in this work.

This study proposed a new approach to impliment a robusut control of comsumer-friendly flexible manipulator with five joint for untact working in filed work-site. The output redefinition approach was used to overcome the non minimum phase characteristic of the system. The new output is defined so that the zero dynamics related to this output are stable. The control strategy is based on an computed torque method which is applicable to a class of time-invariamt phase linear systems whose uncertainties appear in output loop stable. The controller is composed of a stabilizing joint controller and an output redefinition tracking controller. Experimental results are also presented to verify the effectiveness of the proposed control scheme.
