This study was compared with each 2 groups (Intermittent traction therapy alone group1: Control group and Intermittent traction therapy plus Auriculotherapy group 2: Experimental group) on 20 HIVLD(Hemiated Intervertebral Lumbar Disk) patients with sciatics Each subjects were divided to control and experimental. Each group were applied Intermittent traction therapy (HOld:25, Rest:15) for 15 minute and control group were not received auricular stimulation. However experimental groups were applied auricular stimulation simultaneosly. Auricular acupuncture points(max-17, min=13) were stimulated with low frequency. high intensity Electro-Acupunture stimulator for 20 seconds per each point. Treatment and measurements(R.P and VAS) was administered to each patient during the 10 times therapy per 2 weeks. The results were significant differences between the two groups. Experimental group appeared significantly greater than before in pain, and pain relief, and significant improvement in centralization phenomenon of radiating pain.

We examined the chronic effect of dextromethorphan(DM) on the cellular immune responses in mice. T cell simulator, phytohemagglutinin did not show singificant effect on lymphocyte proliferation. Costimulator of T and B cell, pokeweed mitogen, and B cell stimulator, lipopolysaccharide exhibited DM-induced decreased lymphocyte proliferation. Singificantly suppressed natural killer (NR) cell cytotoxicity was evidenced following 6 months DM exposure. These results suggest that chronic DM administration pertub B cell functioning and NK cell cytotoxicity. In addition, prenatal DM exposure did not potentiate the immunomodulation in postnatal effect induced by chronic DM.

This research attempts to develop a method to relieve dysmenorrhea, which is an obstacle to many women's social activities, by designing a smartwear with built-in thermotherapy and TENS device. TENS therapy has the advantages of being controlled by patients and not depending on the use of drugs. The TENS device is designed as a stomach band so as to be unnoticeable to others when outer clothes are worn; the size was minimized and attached to underwear to facilitate use everywhere at any time. A current problem is the limitation of minimizing, but as battery technology is further developed, we can anticipate much smaller devices. The development of aforementioned smartwear function will increase women's choices in occupations and general improvement in quality of life.

This study compared the effects of Intermittent traction therapy alone(Group1=Control group) and Intermittent traction therapy plus Auriculotherapy (Group2=Experimental group) to 20 Sciatica patients. Subjects were assigned to two groups with each 10. The two groups received Intermittent traction therapy (Hold:25, Rest:15) for 15 minute and experimental group did received auricular stimulation. Auricular acupuncture points(max=17, min=13) were stimulated with low frequency, high intensity Electro-Acupunture stimulator for 20 seconds per a each point. Treatment and measurements(SLR and VAS) was administered to each patient during the two weeks of 10 times therapy. The results were significant differences between the two groups. Experimental group produced significantly greater pain relief, and significant improvement of limited SLR.

Virtual Reality(VR) is a new technology which makes humans communicate with computer. It allows the user to see, hear, feel and interact in a three-dimensional virtual world created graphically. In this paper, we introduced VR into psychotherapy area and developed VR system for the exposure therapy of acrophobia. Acrophobia is an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used as a treatment. Lately the virtual reality technology has been applied to that kind of anxiety disorders. A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. In this study, the elevator stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a feel of phobia and without phobia, heart rate was measured during experiment. And also measured a person's HR after the virtual reality training. In this study, we demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

Recently, the number of consumers who buy various goods using the shopping channels on cable TV has increased. The objectives of this study are to examine the propensity of consumers to make an impulse purchase through cable TV, and to investigate the factors that influence consumers' impulse purchase. The following was found in this study: (1) The propensity of consumers to make impulse purchases on cable TV is somewhat low, Among sub-areas of impulse purchase, the propensity to make impulse purchase by suggestion is the highest. (2) Among the variables that affect consumers' impulse purchase on cable TV, the most influential variable is the psychological factor, followed by the frequency of shopping on cable TV, positive testimony from consumers who have used the product, and the amount of time spent in watching shopping channels on cable TV, in that order.

The surface EMG signal detected from voluntarily activated muscles can be used as a control signal for functional electrical stimulation. To use the voluntary EMG signal, it is necessary to eliminate the muscle response evoked by the electrical stimulation and enable to process the algorithm in real time. In this paper, we propose the Gram-Schmidt(GS) algorithm and implement it in FPGA(field programmable gate array). GS algorithm is efficient to eliminate periodic signals like muscle response, and is more stable and suitable to FPGA implementations than the conventional least-square approach, due to the systolic array structure.

This paper proposes a helmet-type whole-head brain stimulator system considering a realistic head geometry. For more accurate design and computer simulations, a realistic volume conductor model was adopted and the current evoked on human cerebral cortex was analyzed using the boundary element method (BEM). To obtain a more focalized evoked current around the target points, various coil configurations were tested and an average targeting error of about 10 mm was obtained.

In this paper, we devised electrical thermal stimulator for meridian point. The system consist of has four channel applicator, power controller and computer. The applicator consist of resistance wire heater and thermal sensor. A stimulation patterns are obtained from a real moxa combustion. The developed system does not make any smog, does not need moxa anymore, only need electricity.
