  • Objective: This study aimed to get information on the current status of therapies to date for non-alcoholic fatty liver disease (NAFLD), including non-alcoholic steatohepatitis (NASH). Methods: All randomized clinical controlled trial (RCT)-derived papers for NAFLD or NASH were reviewed via PubMed Database. Results: 39 RCTs met the review criteria, of which 15 and 24 papers were for NAFLD and NASH, respectively. 83% of the papers were released since 2006, and 30 studies were conducted for western medicines, antioxidants and lifestyle intervention whereas nine trials were done using herbal medicine or acupuncture which showed positive outcome. Conclusions: NAFLD and NASH are new epidemic disorders which can be a target of traditional Oriental medicine. This study will be helpful for the Oriental medicine-based strategies or therapeutic development for them.

  • This article presents the experimental studies of controlling angle and position of the inverted pendulum system using neural network to compensate for errors caused due to fuzzy controller. Although fuzzy control method can deal with nonlinearities of the system, fixed fuzzy rules may not work and result in tracking errors in some cases. First, a nominal Takagi-Sugeno (TS) type fuzzy controller with fixed weights is used for controlling the inverted pendulum system. Then the neural network is added at the reference input to form the reference compensation technique (RCT)control structure. Neural network modifies the input trajectories to improve system performances by updating internal weights in on-line fashion. The back-propagation learning algorithm for neural network is derived and used to update weights. Control hardware of a DSP 6713 board to have real time control is implemented. Experimental results of controlling inverted pendulum system are conducted and performances are compared.

  • Objectives:In this study, we surveyed papers about Oriental herbal medicines(prescriptions and herbs) for dementia. Method:We collected 64 research papers on Oriental herbal medicines(prescriptions and herbs) for dementia in the internet site OASIS using the keyword dementia. Then we analysed them according to year, research method, etc. Result & Conclusion:The absolute majority of research papers on Oriental herbal medicines(prescriptions and herbs) for dementia was experimental papers.

  • Chronic non-specific low back pain (CLBP) is one of the major health problems casting substantial amount of economic expenses and negative impact on quality of life onto an individual as well as society. On contrary to public familiarity, the ways of management of CLBP are diverse and there is yet no general consensus about which approach is better than others or to whom the specific management should be applied. Some hold the negative point of view on the efficacy of the invasive maneuver such as epidural injection because there is no controlled clinical trial (RCT) yielding better long term outcome of those invasive managements over conservative ones. But the experts of interventional or surgical treatment stress the methodological difficulty in performing RCT and assert that those invasive treatments can bring the prompt and complete resolution of low back pain and restoration of function in appropriately selected cases. These seemingly opposite views on the invasive management on CLBP are rather complimentary each other than to be contradictory.

  • The osteoporosis is a disease that represents a reduction in the volume of bony tissue relative to whole bone volume. And mandible also may be affected. Such porotic mandible may influence the result of the surgery like dental implant surgery relating mandible. So, the author examed the panoramic view of 89 persons for finding the possibility of useful diagnostic parameters of osteoporosis. To know the correlationship between the condition of vertebra and mandible, bone marrow density of lumbar spine from 2nd to 4th, and the number of residual tooth, panoramic mandibular index (PMI), angular cortical bone thickness (ACT) and ramus cortical bone thickness (RCT) were compared. The result is that PMI and ACT have similar relative weak linear correlationship, RCT have very weak linear correlationship, the number of residual tooth have not linear correlationship.

  • In this paper, experimental studies of a neural network (NN) control technique for non-model based position control of the x-y table robot are presented. Decentralized neural networks are used to control each axis of the x-y table robot separately. For an each neural network compensator, an inverse control technique is used. The neural network control technique called the reference compensation technique (RCT) is conceptually different from the existing neural controllers in that the NN controller compensates for uncertainties in the dynamical system by modifying desired trajectories. The back-propagation learning algorithm is developed in a real time DSP board for on-line learning. Practical real time position control experiments are conducted on the x-y table robot. Experimental results of using neural networks show more excellent position tracking than that of when PD controllers are used only.

  • This paper presents the implementation of an educational kit for intelligent system control education. Neural network control algorithms are presented and control hardware is embedded to control the inverted pendulum system. The RBF network and the MLP network are implemented and embedded on the DSP 2812 chip and other necessary functions are embedded on an FPGA chip. Experimental studies are conducted to compare performances of two neural control methods. The intelligent control educational kit(ICEK) is implemented with the inverted pendulum system whose movements of the cart is limited by space. Experimental results show that the neural controllers can manage to control both the angle and the position of the inverted pendulum systems within a limited distance. Performances of the RCT and the FEL control method are compared as well.

  • Recently, interest in detoxification therapies is increasing. Coffee enema has been most frequently used as one of detoxification therapies. However, there is lack of scientific basis for coffee enema, regarding its clinical efficacy and safety respectively. This study aimed to produce the general features of coffee enema such as definition, protocols, clinical applications and efficacies, and side effects. Total 37 articles coffee enema were collected from 7 databases including PubMed, and reviewed thoroughly. The majority of papers were review studies or case reports for effects/side-effects of coffee enema. The quality of papers was generally poor, and no randomized controlled clinical trial (RCT) was exist. This study shows the current status of coffee enema-related study, and suggests the demand for RCT study to develop the evidence-based detoxification therapy using coffee enema.

  • Objective: The purpose of this study is to investigate recent clinical studies on the effects of acupuncture on dementia. Method: We searched RCTs (randomized controlled trials) using the database PubMed (2000-2018). Clinical RCT studies of acupuncture used to treat dementia in humans were included. Nine randomized controlled trials were included. Results: Various acupoints such as Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), and Shenting (GV24) were used to treat symptoms. The studies reported a decrease in evaluation criteria, such as the Mini Mental State Examination (MMSE) and activities of daily living (ADL), for measuring cognitive ability. The acupuncture process, the results for outcome measure, and the effectiveness of studies were analyzed. We then assessed "risk of bias." Conclusions: Through this review, we found that acupuncture is applicable for the treatment of dementia. This can be used for future study.
