  • It is as result that study to apply mini magnet nerve curer in peripheral nervous system disease treatment. Simulator and embodied action power and Control Unit in cylinder form of magnet roof object firstly. Yielded service area about special quality of probe of loop object cylinder style and treatment area dimension and distance of treatment pulse secondly. Embody pulse forming course energy value by Probe's form by third, could embody treatment pulse by disease. Specially, through a special quality experiment, saved Damping pulse form and treatment digital forming etc. variously. Lately, embodied this to aid a little in disease treatment that follow that there is no invasion that there is no stimulation by medicine development. Neuralgia, muscular disease and Altzheimer, with stroke etc. is becoming the matter of concern and interest which disease of adult etc. it is same is important. And the melancholia in compliance with the modern direction of a ceremony which is complicated and garrulous, trillion it will cry and symptoms, it is a tendency where the emotional obstacle etc. nervous psychiatric disorder patient is increasing at class speed. But currently the applicator it will be able to treat like this disease almost it is a condition which is wholly lacking. Consequently like this disease it used magnetic stimulation and it diagnosed and the equipment it will be able to treat plan and it embodied.

  • 전통적인 강의실의 기초통계학 수업에서 많은 학생들이 수업에 집중하지 못하고 있다. 수업 시간에 졸거나, 잡담하거나, 휴대폰을 만지작거리면서 다른 생각에 잠겨 있다. 인터넷이 가능한 컴퓨터실에서의 강의와 실습은 인터넷이 제공하는 콘텐츠와 부단히 경쟁을 해야 한다. 이러한 문제를 조금이나마 해결해 보려고 시도한 방안이 교수와 학생을 하나의 유무선 네트워크로 묶는 교육용 디지털 신경시스템 하에서 기초통계학을 가르치고 학생들이 공부하게 하자는 것이다.

  • 최근 3D TV 보급과 확산에 따른 시각 피로문제가 대두되면서 시각 기능과 인지적 관점에서의 연구가 활발하다. 그러나 3D 시각피로가 자율신경계 기능에 미치는 영향에 대한 연구는 미비하다. 따라서 본 연구에서는 3D TV 시청으로 유발되는 3D 시각피로가 자율신경계 기능에 미치는 영향과 이 영향이 교감 및 부교감 신경계와 심혈관계 반응에 미치는 영향을 확인하고자 한다. 피험자는 20 대 남녀 대학생 15 명(남 6 명, 여 9 명, 평균나이 22.53 세 ${\pm}$ 2.55 세)을 대상으로 하였다. 피험자는 편안한 의자에 앉아 3D TV를 1시간 시청하였다. 3D TV 시청 전과 후의 1분간 맥파(PPG, Photo-PlethysmoGram)를 측정하였고 주관설문을 실시하였다. 측정된 신호에서 SDNN (standard deviation of RR intervals), RMS-SD(root mean square successive difference), HF/LF ratio, Ln(LF), Ln(HF)를 추출하여 교감 및 부교감 신경계, 그리고 심혈관계 반응을 확인 하였다. 연구 결과 HF/LF ratio, Ln(LF), Ln(HF)는 시청 후에 유의하게 감소하였고, SDNN, RMS-SD는 통계적 유의차를 확인할 수 없었다. 이 결과는 3D 시각피로가 자율신경계 기능에 영향을 미치고 이로 인해 교감신경계가 항진되는 반응이 나타나며, 심박 변화율이 감소하는 결과를 초래할 가능성을 확인 하였다.

  • Mbu-3 is a novel mouse brain unigene that was identified by digital differential display. In this study, expression of the gene was chased through developmental stages and the protein product was identified in the brain. The cDNA sequence was 3,995-bp long and contained an ORF of 745 AA. Database searches revealed that the chicken SST273 gene containing LRR- and Ig-domain was an mbu-3 orthologue. Tissue specificity for the gene was examined in embryos and in brains at post-natal and adult stages. During the embryonic stages, mbu-3 was localized to the central nervous system in the brain and spinal cord. In the early post-natal stages, the gene was evenly expressed in the brain. However, with aging, expression was confined to specific regions, particularly the hippocampus. The protein was approximately 95 kDa as determined by Western blot analysis of brain extracts.

  • The purpose of this study was to determine the changes of skin temperature and subjective fatigue of the thoracic vertebrae by the chiropractic adjustments. Stimulation of the sympathetic nervous system will cause the changes in the skin blood flow which can be detected by measuring the skin surface temperature. This study was to see whether chiropractic adjustments could affect the activity of the sympathetic nervous system as reflected by changes in skin temperature of the thoracic. Skin temperature and subjective fatigue on 16 subjects was measured before, within 10 sec, 10min, 20min and 30 min after a thoracic adjustment with Digital Infrared Thermal Imaging(DITI) and Visual Analogue Scale(VAS). The adjustments consisted of a straight posterior-to-anterior high-speed, low-amplitude thrust to the transverse process of T3-T10 using a reinforced hypothenar contact. The average temperature and fatigue changed when the spine was considered as an entire unit. These results illustrate that the blood flow through the soft tissue can be affected by specific adjustments to the spine. This study might be served as an useful baseline data for the changes of the circulation and fatigue after the chiropractic adjustments.

  • Objectives: This study is designed to identify the responses of autonomic nervous system and gastrointestinal function which are induced by acupuncture at abdominal anterior cutaneous nerve. Methods: This study is one group before and after pilot study. Subjects were treated once, after having been fasting six hours. They had before tests, labeling points for acupuncture, acupuncture, and after tests in order. The points of acupuncture were motor points of rectus abdominis where the abdominal anterior cutaneous nerve came to the skin from abdominal wall. Before and after tests were consisted of three things: Digital Infrared Thermographic Imaging(D.I.T.I.), Heart Rate Variability(HRV), and Recording of bowel sounds. Results: There were significant differences on the skin temperature of upper body and the frequency of bowel sounds(p<0.001, p<0.001). The HRV parameters and volume of bowel sounds had no significant differences(p>0.05, p>0.05). Conclusion: Even though no significant differences in HRV parameters, the significant differences of skin temperature of upper body and frequency of bowel sounds could mean acupuncture at abdominal anterior cutaneous nerve could affect the autonomic nervous system and gastrointestinal function. However, this study had no group to compare with. Future randomized project should address this issue.

  • Objectives : This study was designed to investigate the effect of PC6 and SP4 on autonomic nerve system in healthy adults. Methods : 22 healthy adults were recruited and randomized into the study group or control group. The study group (real acupuncture group) was acupuncturcd on PC6 and SP4. The control group (sham acupuncture group) was acupunctured superficially near PC6 and SP4 but not the exact points. The subjects rested for 10 minutes, and were then acupunctured. After 15 minutes, acupuncture needles were removed and the subjects rested for another 15 minutes. Heart rate variability(HRV) was continuously measured during the study period by FM-150 (digital Holter ECG recorder). Results : In the real acupuncture group. LF(low frequency) significantly decreased during the acupuncture period(p<0.05). LF/HF ratio also had a significant decrease during acupuncture period and the decrease was maintained during the post-treatment period as compared with the pre-treatment period. In the sham acupuncture group. LF significantly increased during the acupuncture period but LF/HF ratio had no significant changes. Conclusions : The results suggest that acupuncture on PC6 and SP4 can increase parasympathetic activity and balance autonomic nervous system.
