Objective : The purpose of this study is to estimate the effects of spiral taping treatment on low back pain. Methods : 420 low back pain patients were treated with spiral taping or spiral taping plus herbal medicine, and no other treatments such as acupuncture, herbal acupuncture, and chiropractic therapy were added. We evaluated the improvement by physical examination and pain. Results : 364 patients felt no pain or inconvenience of daily life and 43 patients showed improvement of pain or symptom after 1 month of treatment. 13 patients showed same pain with before treatment. Conclusion : These results suggest spiral taping treatments contribute to the improvement of low back pain. Further study is needed for the confirmation of this effect of spiral taping treatments on low back pain.

본 연구는 스파이랄 벡터에 기초한 유도전동기 모델의 해석을 나타내고 이 해에 기초한 자계가속법(Field Acceleration Method)에 의해 순시 토크 제어와 회생전력 해석을 나타내었다. 전압지령형의 PWM제어에서 전압형 인버터에 의해 전동기가 동작할 때 전력회생이 수식으로 해석 되었다. 전압지령형의 전압 PWM 인버터에 의한 유도 전동기의 속도 서보시스템을 설계하고 이 속도제어 시스템을 이용해 가감속시의 소비(회생)전력을 측정하여 실제 시스템에서 전력 절약정도를 검토하였다. FAM법에 의한 실험을 행하고 유효성을 확인하였다. 고정자 저항의 측정오차나 변동은 여자전압에 맥동이 생겨 출력 토크에 영향이 나타는 것을 알 수 있었다.

This paper presents a solution that an analytical model for an induction motor and the formula of regenerative power and instantaneous torque are derived. based on the spiral vector. The torque is controlled linearly through variations of the slip angular velocity, based on the field acceleration method (FAM). And also PWM inverter fed induction motor drives is schemed to be easily a regenerative drive. The voltage source inverter fed induction motor drives that regenerative power occurs with back current type is presented, to easily controlled the feedback power and to proper the adaption of energy shaving drives. The experimental tests verify the performance of the FAM, proving that food behavior of the drive is achieved in the transient and steady state operating condition, and are discussed to save the power that regenerative power is measured at the operating acceleration or deceleration of servo system.

This study was conducted to investigate the influence that it has on the application pre and post balance index using method with spiral and reaction point balance taping application against 20 stroke patients. The taping application pre and post static eye opening balance index was statistically no significant difference in the Mean X Speed, and the Extent in X Dirction but in the Mean Y Speed, the Velocity Moment, and Extent in Y Direction, there were statistically significant difference(p<0.05). The taping application pre and post static eye closing balance inde was statistically no significant difference in the Mean X Speed, in Y Direction, there were statistically significant difference(p<0.05). From above results, the method of the applied taping was the equilibrium stability performance of the Y-axis than the stability of the balance of the X-axis, therefore it is considered to study the taping application method in the balance of detail stroke patients.

Objectives : Low back pain is common symptom in clinics. The purpose of this study is to examine the effects of spiral taping on the low back pain patients. Methods : A total of 60 patients with low back pain were assigned to two groups : taping group and non taping group. Patients were evaluated and analyzed VAS, ODI(Oswestry Disability Index), lumbar flexion angle and lumbar extension angle. Results and Conclusion : 1. VAS score of pain was significantly decreased in the taping group(p<.05), compared with the non taping group. 2. Lumbar flexion angle was significantly increased in the taping group(p<.05).

The purpose of this study is introduce the spiral taping treatment on Temporomandibular Disorder in oral Medicine. The taping treatment is relatively simple and dosen't have any adverse effect, so it has high stability and superior effect of treatment. In this study, using the spiral taping treatment as one of the effective taping treatments, non-stretched tape was attatched to the muscles which set limit to the range of joint movement and cause pain to temporomandibular joint. With that treatment this study tried to make effective results of treatment of temporomandibular disorder. These results suggest spiral taping treatments contribute to the improvement of tempermandibular disorders. Further this study is needed for the confirmation of this effect of spiral taping treatments on temporomandibular disorders.

This study is carried out experiments on various factors for improving the grade of low grade scheelite by Knelson concentrator prior to the main beneficiation process. Even though there are several gravity separators such as Jig, Spirals and etc. for rougher concentrate, the KC3 Knelson Concentrator was adopted to get better separation efficiency and beneficiating effects for pre-concentration of the low grade scheelite ore. The feed samples was prepared to minus 1mm in size by crushing and grinding. The important factors in the KC3 Knelson Concentrator test were examined in terms of the variations such as number of treatment, feed rate, rotation speed of bowl(G force), water flow rate, pre-removal of magnetic minerals, feed size and feed grade. According to the result of experiment, it shows that the important technical variations are limited in terms of number of treatment, feed rate, feed size and feed grade. The final result shows that the KC3 Knelson Concentrator obtains the scheelite pre-concentrate of about $3%WO_3$ grade and 90% recovery, respectively, from the feed containing about $0.8-1.0%WO_3$ grade.

The Yellow Sea and northern East China Sea contain a transgressive sand layer. Numerous sedimentary studies have been carried out in these sand deposits using seismic exploration and core sediment techniques, but few mineralogical studies have been reported. The major purposes of this study are to describe the distributions of heavy minerals throughout the Yellow sea and northern East China Sea and to identify the provenance of coarse sediments using the mineral chemistry. Eight heavy mineral species were identified in the study area (epidote, amphibole, garnet, zircon, sphene, rutile, apatite, and monazite). The study region was divided into six areas (areas A to F) based on heavy mineral distributions and sampling locations. In mineral chemistry, the amphiboles present are classified as edenite and hornblende in the calcic amphibole group, and the garnets are identified primarily as almandine in the pyralspite group. A combined data set of heavy mineral distributions and mineral chemistry showed clear differentiation of the characteristics of the six classified areas, enabling determination of provenance and sedimentary environment. Area A and B in the eastern Yellow Sea were originated from the Korean peninsula, and these regions showed different heavy mineral characteristics by tidal current and coastal current. In addition, monazite was only found in the area B and could be used as an indicator from the southwestern Korean peninsula. Area D and E in the western Yellow Sea showed the characteristics of sediments originating from the Huanghe, and sediment in the area E was derived from the Changjiang. Area C in the northern East China Sea appeared to have Changjiang-origin sediment, and abundant apatite indicated that area C was formed close to the Last Glacial Maximum.
