The purpose of this study was to determine the effects of high voltage pulsed current (HVPC) stimulation on wound healing. Thirty-four Sprague-Dawley adult female rats were assigned to experimental and control groups. Each rats were anesthetized with pentotal sodium, and a 10 mm full-thickness incision was made on the back. From 24 hours after surgery, the rats of experimental groups were stimulated with HVPC, $140{\mu}s$, 120 pps, 30-40 V for 30 minutes, daily. The rats were sacrified 2 days, 4 days and 6 days after stimulation, respectively. The skin was removed, and processed for light microscopic examination. The length of incisional wounds were measured by microcaliper, and nucleolar organizer regions were counted under light microscope. For the histological observations the specimens were stained with Hematoxylin and Eosin, Masson Trichrome, Gomori Reticulum and Ag-NOR. There was a significant decrease in the length of incisional wound in experimental group compared with control group at 6 days HVPC stimuation (p<0.05). In experimental group, wound were significant difference (p<0.01) between the duration of post surgery. The mean numbers of nucleolar organizer regions per nucleus were significantly increased in the experimental group at 6 days HVPC stimulation (p<0.05), and were significantly difference (p<0.01) between the duration of post surgery in experimental group. Histological examination of the wound site suggested a more rapid of epithelialization and collagen formation between experimental groups compared with control groups. The result may indicated that the HVPC with $140{\mu}s$, 120 pps, 30-40 V for 30 minutes promoted surgical wound healing in the rat.

Purpose: This study examined the effect on postural control during the stimulation of haptic touch with fingertip on the stable surface at quiet standing posture, squat flexion stage, 60 degrees squat stage and squat extension stage. Methods: The postural sway was measured on the force platform, while 30 subjects were squatting, under three different haptic touch conditions (No Touch [NT], Light Touch [LT], Heavy Touch [HT]), above the touch pad in front of their body midline. Three different haptic touch conditions were divided into 1) NT condition; squatting as right index fingers held above the touch pad, 2) LT condition (<1N); squatting as the touch pad was in contact with right index fingers pulp with a pressure not exceeding 1N and 3) HT condition; squatting as subjects were allowed to use the touch pad for mechanical support by transmitting onto it with as much force, choosing with their index fingers. Results: There was significant decrease in LT, rather than that of NT (p<0.01), and in HT, rather than that of LT (p<0.01), as the results of the distance and velocity of center of pressure (COP) in mediolateral direction at quiet standing position. In anteroposterior direction, the distance and velocity of COP in LT and HT showed significant decrease, when compared to that of the data of NT (p<0.01). There was no significant difference between the 3 conditions (NT, LT, and HT), with respect to the distance and velocity of COP in mediolateral direction, during dynamic balance (squat flexion stage, squat extension stage) (p>0.05). In anteroposterior direction, the results of the distance and velocity of COP in HT showed significant decrease when compared to that of the data of NT (p<0.05). Conclusion: Light touch, during the task, decreased the postural sway at static balance. The results suggest that haptic touch should be applied, appropriately, because it varies the effects according to different conditions.

In this study, we have fabricated a fiber-optic radiation sensor using an organic scintillator for high energy electron beam therapy. The intensities of scintillating light from a fiber-optic radiation sensor are measured with different field size, electron beam energy and monitor unit of a clinical linear accelerator. To obtain percent depth dose(PDD), the amount of scintillating light is measured at different depth of polymethylmethacrylate(PMMA) phantom. Also the intensity of Cerenkov light is measured and characterized as a function of incident angle of electron beam and a subtraction method is investigated using a background optical fiber to remove a Cerenkov light.

Purpose: Heat therapy by heat lamp after microvascular surgery is being used for preventing blood vessels's contraction and blood-flow's disturbance. As usually, incandescent lamp has been used. But there have been several problems and need for improvement in the existing heat lamp treatment. So we would like to introduce improved heat lamp to keep an appropriate temperature and intensity of illumination. Methods: The existing heat lamps are the ones of general light stands covered with newspaper, having 60 watt light bulb of incandescence and lampshade made of aluminum. We have tried to improve shortcomings of the existing heat lamps by enlarging the size of aluminum lampshade and attaching a curtain that can block heat and light. We conducted a comparative study between the existing and improved heat lamps. Under the assumption that there are several affected parts, we have also measured the distance from heat lamp to patients' eye region and then intensity of illumination. Result: The target temperature of surface was realized in 11 minutes with the maximum temperature reaching at 36.6 degrees C in 28 minutes at the existing heat lamp while the target temperature reached in 7 minutes with the maximum temperature reaching at 39.0 degrees C in 17 minutes at the improved heat lamp. The existing and improved heat lamp showed 38 lx and 0.1 lx of intensity of lumination, respectively. Conclusion: Using improved heat lamps, we can keep an appropriate temperature and we think we can make contribution to patients' treatment by making them and their neighbors able to sleep with minimized disturbance thanks to low intensity of illumination secured by blocking light.

Horticultural therapy is a complementary therapy by trained professionals utilizing plant and horticultural activities as media to pursue the positive change of clients, which resulting from stimuli of plant nature, activities, and interaction with other people. Outdoor horticultural activities provide clients with the opportunities of the contact to nature such as fresh air and sunlight as well as plants. But the importance of plant nature to client's health has not been fully acknowledged compared to that of therapist's role and activities in horticultural therapy in Korea. In horticultural therapy it is possible for client to participate on the various levels from passive viewing to active gardening according to the client's ability. Therefore it is necessary for horticultural therapists to consider the therapeutic factors of plant nature to maximize the therapeutic effect of horticultural therapy. The purpose of the research is to clarify the therapeutic factors in the contact of client with plant nature and to emphasize those importance in horticultural therapy. From the review of the experimental researches five therapeutic factors were revealed: Natural light, plant natural view, natural sound, aroma(volatile oils of plants), and plant itself. This paper raises the importance of outdoor activities in horticultural therapy and the necessity for severely handicapped clients to the contact with plant nature, though passively.

IR classified by wavelength three parts NIR, MIR. FIR. There is FIR which is radiated from healthy human body the wave length is 8-14m. The Sun's ray is composed of Infared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(60%), IR(20%), and UV(20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time, in the Industrial Revolution the Infrared and FIR had been begun to use making products. FIR with low temperature can deeply penetrate on the human body composed things without troublesome, since FIR has effectively operated on the human body at low temperature (35-40 $^{\circ}$C). In this study, we experimented in the specific temperature FlR radiation intensity. water consumption rate, feed consumption rate. survival rate and mean of weight balance with FlR radiation instrument. According to the results, the FlR radiation to the mice assisted to increase the survival rate.
