Purpose: This study aimed to investigate the fully immersive virtual reality (FIVR) program changes in the autonomic nervous system (ANS) by age according to heart rate variability (HRV). Methods: A total of 44 subjects were classified into group 1(aged 20-30), group 2(aged 40-60), and group 3(aged 70 and above). The study analyzed the HRV using a pulse wave analyzer and compared the ANS changes before and after applying the FIVR of the group. The LF, HF, RMSSD, and SDNN were measured. Fifteen minutes of virtual reality applications were applied to all subjects, and 1 min of rest was given in the middle of the session. A was used for anteroposterior comparisons of the ANS. Results: The HF, LF, RMSSD, and SDNN values were not statistically significant in all groups, but they all increased. The RMSSD value was statistically significant because it increased in group 3 (p<0.05). Those of the other two groups were not statistically significant (p<0.05). Conclusion: An FIVR program does not have a negative effect on the ANS response.

The purpose of this study was to analyze the effect given to the variable details which disturb the flow of blood in brain artery disease through Aerobic exercises. It chose the subjects of study : 5 persons in an exercise group and 5 persons in a non-exercise group. Peak brain blood velocity, mean velocity, and resistance & artery stricture ratio were measured with TCD, measure machine for brain artery blood flow. The conclusion of the study was as follows: 1. At pre-test of an exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed much lower in the variation of left common carotid artery(LCCA). 2. At post-test of an aerobic exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed just a little decrease ratio but were not significant different in the variation of left common carotid artery(LCCA). Viewing on the base of these result, continuing exercises promote the functional improvement of the heart blood system and were showed the positive variation of artery stricture ratio according to brain blood flow velocity, the pulse and resistance or blood velocity. Therefore programs for prescriptions through aerobic exercises must be developed in many ways.

Objective: To review the clinical basis of the Sa-Ahm 5 Element acupuncture originated about 360 years ago, papers and books were researched. Methods: Total of 58 books and papers ranging from ancient Huang Di nei jing to modern Bio Medical Acupuncture for Pain Management were investigated to study the clinical practice of it. Results: It could be practiced differently depending upon the viewpoints of diagnosis. They are ranging from theories of the greater-less of Yin and Yang, 7 emotions, organs- visceras, 8 diagnostic criteria, and pulse diagnosis to meridian circulation. Conclusions: It needs to be set clinical guidelines by which to practice Sa-Ahm acupuncture though it is nowadays mostly-used method in accordance with practitioner's viewpoints.

Mesenteric torsion was diagnosed in a 2-year-old, spayed female Miniature Schnauzer. The patient was presented with acute depression, vomiting, lethargy and hematochezia. On physical examination, severe dehydration, tachycardia, tachypnea, weak femoral pulse, delayed capillary refill time and pale mucous membrane were found and the dog was in shock. Radiography and ultrasonography revealed intestines distended with gas, ascites and the "C" shaped distended intestine. Medical treatments including fluid therapy, analgesics, antibiotics and lidocaine for reducing reperfusion injury were applied. And then, the mesenteric torsion was definitively diagnosed through exploratory laparotomy and intestinal resection and anastomosis were performed. The dog made an uneventful recovery and was free of clinical sign one week after surgery. Mesenteric torsion is an unusual and life-threatening disease in dogs. It has usually been described in the middle and large breed dogs, especially German Shepherds. However, the mesenteric torsion should be included in the differential diagnostic lists for acute abdomen even in small breed dog. The mortality rate of mesenteric torsion can be reduced through prompt diagnosis, proper preventive therapy for shock and reperfusion injury and emergency surgery.

The apparatus has been fabricated using the laser diode and microprocessor unit. The apparatus used a InGaAlP laser diode for laser medical therapy and was designed for a pulse width modulation type to increase stimulation effects. To raise the stimulus effect of the human body, the optical irradiation frequency could be set up. The study has executed in-vivo experiment by employing our own developed laser diode irradiation system to investigate the effects of the InGaAlP laser diode irradiation on the wound healing as a preliminary study aimed at the application of InGaAlP laser diode to wound healing of human skin injury. The study cut out whole skin layers of Sprague-Dawley rat on the back part in 1 cm circle and observed developing effects after executing light irradiation for 9 days, and in result it is found that the light irradiation rat showed earlier wound healing than non-irradiation rat during the experimental period. In addition, there are some differences found regarding the healing process between laser diode irradiated rats and non-irradiated ones.

In order to solve the contradiction between requirements of high sampling rate for acquiring accurate energy information of pulses and large amount of data to be processed timely, the method with an algorithm to correct errors caused by reducing the sampling rate is normally used in front-end read-out system, which is conductive to extract accurate energy information from digitized waveform of pulse. The functions and effects of algorithms, which mainly include polynomial fitting with different fitting times, double exponential function fitting under different sampling modes, and integral area algorithm, are analyzed and evaluated, and some meaningful results is presented in this paper. The algorithm described in the paper has been used preliminarily in a prototype system of Positron Emission Tomography (PET) for heavy-ion cancer therapy facility.

Purpose : The purpose of this experiment was to evaluate the pre-application effect of low frequency electrical stimulation(LFES) on VEGF expression of atrophic muscle and to determine the optimal pre-application period of LFES for prevent muscle atropy Methods : Twenty-five adult sprague-dawley rats were randomly assigned to weight bearing group, hindlimb suspension for 14 days group, hindlimb suspension with pre-application of LFES for 14 days group, hindlimb suspension with pre-application of LFES for 11 dsys group and, hindlimb suspension with pre-application LFES for 7 dsys group. 16Hz of Biphasic pulse current was applied to gastrocnemius for 15min per days. Results : VEGF were decreased expression in HSG groups, whereas VEGF were significantly increased in HS+ES14G, HS+ES11G, HS+ES7G groups Conclusion : LFES during the hindlimb suspension showed a positive effect in VEGF induction and early application is strongly encourage VEGF induction. This indicated that pre-application of LFES could prevent muscle atrophy.

헤노흐-쇤라인 자반증의 전반적인 예후는 양호하나 심한 신염의 경우 말기신부전으로 진행될 위험이 높다. 최근 연구는 심한 헤노흐-쇤라인 자반증 신염을 가진 소아에서 조기 치료의 중요성을 강조하고 있으나 심한 자반증 신염의 치료는 맹검 대조 연구가 드물어 여전히 논쟁의 여지가 있다. 그럼에도, 정맥 고용량 메틸프레드니솔론 충격요법, 면역억제/세포독성 약제, 섬유소용해 치료, 항응고제, 항혈소판제, 혈장교환술같은 여러 강력한 치료가 심한 자반증 신염을 가진 소아에서 사용되어 왔다. 이 종설에서는 심한 자반증 신염을 가진 소아의 치료를 중점적으로 기술하였다.
