  • This study was conducted to determine if supplementation with a compound composed of caffeine (50 mg), capsaicin (75 mg), sesamine (30 mg), L-carnitine (300 mg), banaba (50 mg) and lotus (10 mg) enhanced human autonomic nervous activities (ANS) associated with thermogenic sympathetic activity and fat utilization. Ten healthy college males (21.2$\pm$1.0 yr) volunteered for this experiment. Autonomic nervous activities associated with energy metabolism were examined at 30 min intervals for a total of 120-min while at rest and every 5-min during exercise at 50% of the ventilation threshold before and after intake of the compound or placebo with 100 ml of water for 10 days. In addition, heart rate variability power spectral analysis was used to assess human autonomic nervous activities. The results indicated that there were no significant differences in heart rate during rest and exercise among trials. Furthermore, the autonomic nervous activity tended to increase after 10-days of consumption of the test compounds during the experimental period, but the differences did not reach statistical significance. However, before and after the compound test trial there was a significantly higher respiratory gas exchange ratio (rest 0: 0.83$\pm$0.01 vs. rest 3: 0.89$\pm$0.02, p<0.05), carbohydrate oxidation (CHO) rate (rest 0: 44.57$\pm$5.83 vs. rest 2: 63.86$\pm$5.91%, p<0.05) and a lower fat oxidation rate (rest 0: 55.43$\pm$5.83 vs. rest 2: 36.14$\pm$5.91%, p<0.05. In conclusion, the results of the present study suggested that the compound composed of caffeine, capsaicin, sesamine, L-carnitine, banaba and lotus components that was evaluated in this study did not induce a significant increase in human autonomic nervous activities or lipolysis, even though the individual components have been reported to induce increased fat oxidation.

  • 본 논문은 제조설비 자율제어를 위한 상태 정의 및 진단 알고리즘을 소개한다. 사이버-물리 시스템 및 디지털 트윈기술을 통한 스마트 공장 시스템은 기존 제조 공장의 생산성 및 안정성을 높일 수 있어 최근 이슈가 되고 있다. 스마트 공장 시스템이 생산성을 향상시키고 작업자로 하여금 더 나은 의사결정을 할 수 있도록 하며 정상적이지 않은 공정 흐름을 제어하기 위한 자율제어 시스템은 스마트 공장 시스템을 구성하는 중요한 기술 중 하나가 된다. 그러나 통합된 수많은 설비 데이터를 기반으로 자율제어 프로세스를 수행하는 것은 상당한 사전 작업이 필요하다. 따라서 본 논문에서는 제조설비 자율제어를 위한 추상화된 설비 상태를 정의하고 현재 상태를 진단할 수 있는 알고리즘을 제시한다. 이를 통해 통합된 설비 데이터가 아닌 설비 상태를 기반으로 자율제어를 실시하며 더 간단하게 자율제어 프로세스를 진행 할 수 있도록 한다.

  • It has been shown that bilateral decrease of point H4,5,6 in Ryodoraku test is related with gastric dysmotility. This suggested that the system of Kyung-Rak related with anatomical gastric disease may not be the Stomach Meridian, in the view that the system of Kyung-Rak is similar to that of Ryodoraku, and which was not consistent with classical contents of Kyung-Rak principle. Therefore, this paper was done to investigate whether bilateral decrease of point H4,5,6 is a general sign of common gastric disease in Ryodoraku test and to study its relation between Kyung-Rak principle and autonomic nervous system as a mediator explaining Ryodoraku response. As shown in the results of this study, different electrical response of Ryodoraku between patients with dyspepsia of gastric dysmotility and gastric ulcer revealed discrepancy of location indicating anatomical stomach between Kyung-Rak principle and Ryodoraku and instability of explanation of autonomic nerve theory to Ryodoraku. Thus, it presented the possibility that artificial application of Kyung-Rak principle against Ryodoraku may destroy its originality in the clinical field. To correctly use Ryodoraku in the diagnosis or evaluation of disease, Ryodoraku test should be used according to Nakatani's suggestion and clinical indication of which is limited to the diseases complicated with dysfunction of the autonomic nervous system.

  • Objectives The purpose of this study is to evaluate the characteristics of autonomic nervous system in heart-weakened children via analyzing heart rate variability (HRV) compare to healthy children. Methods Among the children who have visited the department of pediatrics at OO oriental medicine hospital, the subjects were composed of 62 elementary school students without cardiac disorder, who have yet develop secondary sexual characteristics. Results 1. Mean HRT and SDNN of the heart-weakened group of children were lower than the healthy group, but with no statistical significance. 2. Heart-weakened children had higher LF norm and LF/HF ratio, but lower HF norm than healthy children. The rest of the Frequency Domain Index have no significant differences. 3. Heart-weak score showed a positive correlation with Mean HRT and LF/HF ratio. Conclusions Heart-weakened children had an imbalance in autonomic nervous system due to increase of sympathetic nerve activity and decrease of parasympathetic nerve activity.

  • Purpose : The purpose of this study was to investigate whether the respiratory cycle and posture can modulate the autonomic nervous system. Methods : Thirty-two healthy men and women, aged 20-30 years, were enrolled in this study. We conducted 2-second and 6-second respiratory cycle with the subjects in standing, sitting, and supine positions, respectively. Their heart rate variability was measured in each position for both cycle lengths. Results : The low frequency/high frequency (LF/HF) ratio is derived from heart rate variability. In the 2-second respiratory cycles, the LF/HF ratios were highest in standing, sitting, and supine position in descending order. There was a significant difference in heart rate between standing and sitting positions (P<.005). In addition, there was a significant difference in heart rate between standing and supine position (P<.000). In the 6-second respiratory cycles, the LF/HF ratios were again highest in a standing, sitting, and supine position in descending order. However, posture was not found to make a significant difference in this case. Conclusion : Respiratory cycle and posture effectively modulated the autonomic nervous system. Further studies of the clinical application of these results should be conducted.

  • Using air conditioner has been increased in home or office buildings in summer. Also various problems related to air conditioning such as disease induction happened by using air conditioner excessively and operating long. Active operation control is needed for occupant's health when air conditioner operates long. We should think ahead to acquire thermal comfort of occupants which represents psychological and physiological reaction for this operation. Research has been progressed to observe activity of autonomic nervous system by trying to quantitate change of thermal comfort. In this study, questions of the subject and change of body's autonomic nervous system were chosen to evaluate thermal comfort during operation of air conditioner for a long time. Electrocardiogram and questions of the subject which is the progress of changing TSV and CSV by occupants indoor were measured when room air conditioner is operated for a long time, and an air-conditioned adaptability of human body was evaluated by acquiring the change rate of autonomic nervous system through analyzing HRV. As a result of the evaluation, change rate of body's autonomic nervous system corresponded to votes of the subject's question generally, but was distinguished from analysis result of warm-cold sensation in a low temperature area.

  • Background : Phentermine classified by "sympathomimmetic amie", is a stimulant of sympatheic tone But there has been no concrete study which presents the influence of phentermine on autonomic nervous system. Analysis of Heart rate variability is reliable, non-invasive and very useful for evaluating function of autonomic nervous system. We tried to elucidate the influence of phentermine on autonomic nervovs system by heart rate variability. MethodsAmong the 70 candidates who participated in the double-blind case control study whichwas designed in purpose of approving whether- Adipekⓓ is effective for treatment of obesity, 45persons were folled up. From April, 2005 to May 2005, HRV of the candidates who takes phentermine or placebo for 1month, was recorded using BFM-5000ⓓ(medi-core) for 5 minutes in resting state. HRV measures were assessed by time-domain and by frequency- domain analysis. Time domain parameters contain SDNN(Standard Deviation of NN intervals) and RMSSD(Root-Mean-Square of Successive Differences), etc and frequency domain Parameters contain Total Power(TP), Low frequency(LF'0.04-0.15Hz) power. High Frequency(HF:0.15-0.4Hz) power and LF/HF ratio etc. Results: Intakes of phentermine reduce HRV significant1y. SDNN & RMSSD, the main tine domain parameters of HRV, were decreased significantly(P=0.007. 0.016). PSI(Physical Stress Index of Pressure Index) was increase significantly(P=0.002)The main frequency domain parameters(TP, LF & VLF), also decreased significantly. (P=0.024,0.033, 0.015)Conclusion: The result showed that intakes of phentermine reduce heart rate variability and influence on most parameters of HRV. So phentermine not only accelerates sympathetic tone, but also inhibit the balance and function of autonomic nervous system.
