In this paper, we deal with the problem of controlling an unknown nonlinear dynamical system, using wavelet network. Accurate control of the nonlinear systems depends critically on the accuracy and efficiency of the function approximator used to approximate the function. Thus, we use wavelet network which shows high capability of approximating the functions and includes the free-selection of basis functions for the control of the nonlinear system. We find the dilation and translation that are wavelet network parameters by analyzing the time-frequency characteristics of the controller's input to construct an initial adaptive wavelet network controller. Then, weights is adjusted by the adaptive law based on the Lyapunov stability theory. We apply this direct adaptive wavelet network controller to control the inverted pendulum system which is an nonlinear system.

The fusion of fuzzy set theory and neural networks technologies have concentrated on applying neural networks to obtain the optimal rule bases of fuzzy logic system. Unfortunately, this is very hard to achieve due to limited learning capabilities of neural networks. To overcome this difficulty, we propose a new approach in which rough set theory and neuro-fuzzy fusion are combined to obtain the optimal rule base from input/output data. Compared with conventional FNN, the proposed algorithm is considerably more realistic because it reduces overlapped data when construction a rule base. This results are applied to the construction of inference rules for controlling the temperature at specified points in a refrigerator.

Objective : The purpose of this study is to review the randomized clinical trials of Chuna manual therapy for cervicogenic headache and provide a evidence for the efficacy of Chuna manual therapy. Methods : We searched randomized clinical trials that performed Chuna manual therapy for cervical headache up to Feb. 2017 in 6 databases. Randomized clinical trials were selected according to the inclusion criteria and the data were extracted and analyzed. The risk of bias was assessed using the Cochrane Risk of Bias Criteria. Results : 16 RCTs met the inclusion criteria. The meta-analysis of 13 RCTs showed favorable results for the use of chuna manual therapy compared to drug, physical treatment. Conclusions : In 16 RCTs, we found that Chuna manual therapy was effective in cervicogenic headache. However, all RCTs are exposed to a number of bias risks. Therefore, well designed clinical trial would be needed to raise the evidence level of Chuna manual therapy.

Objectives The purpose of this study was to observe clinical reactions (itching, pain, etc.) after Essential Bee Venom (EBV) treatment. Methods This study was conducted 64 patients who had been injected with EBV in Korean Medicine Hospital of Woosuk University and Haeundae Ja-Seng Hospital of Korean Medicine from October 5, 2015 to February 20, 2016. We checked clinical reactions of treatment region. Results 8 patients (12.5%) complained of localized itching and 4 patients (6.3%) complained of localized pain after EBV injection. In itching reaction of patients, 2 patients (15.4%) occurred itching in head and neck, 4 patients (12.9%) occurred in lumbar and back. In pain reaction of patients, 2 patients (6.5%) occurred pain in lumbar and back, 1 patient (11.1%) occurred pain in upper limb. All clinical reactions were happened within 7 treatment times. Conclusions This study suggested EBV treatment can cause clinical reaction like itching and pain. Clinical reactions were more common in inpatients than outpatient, and all reactions were happened within 7 treatment times. Doctors should recognize physical reaction caused by EBV and explain to patient. Further studies are needed to more improved treatment.

Objectives We have attempted to provide the basis of treatment effects by considering foreign & domestic randomized controlled trials (RCTs), being implemented with catgut-embedding therapy for lumbar disc herniation. Methods We found the literatures prepared in Korean, English, and Chinese by December 2014 in electronic databases (Pubmed, Science Direct, Proquest, OASIS, KMbase, NDSL, RISS, National Assembly Library). We choosed RCTs by selection criteria through abstracts & articles, extracted and analyzed data. Cochrane's Risk of Bias Tool was used & implemented for the risk of bias. Results The total of 17 studies were included in the review. 88.2% of studies were accomplished within the last decade. The experimental group has shown more significant effects in 70.6% of studies, and the long-term & partial significant results were obtained in 29.4% of studies. Affected lumbar area and pelvic limb area with radiating pain were mostly selected for acupoint. Conclusions Overall and partial significant results were obtained from 17 foreign & domestic comparative RCTs which substantiates the treatment effects of catgut-embedding therapy for lumbar disc herniation. Since all studies, however, were exposed to the risk of bias, so future research of higher quality shall be necessary.

Aegis Combat System(ACS) is a shipboard combat system developed by U.S. Navy. Its name, Aegis, came from a shield 'Aegis' in greek mythology, which Zeus gave to his daughter Athena. U.S. Navy uses Aegis ships(ships which mount ACS) as their main surface forces. It is known as one of the greatest anti-air warfare ship in the world by its ability to detect air threats with AN/SPY-1, phased array radar, superior Target management and command and control capabilities of the combat system, and SM series interceptors. After first Aegis cruiser USS Ticonderoga was deployed at 1983, U.S. Navy continuously put effort in developing Aegis Combat Systems and Aegis ships. They also improve old fashion existing ships by modernize them. In this Paper, to deduct a lesson which Korea Navy should benchmark, it is went through that a history of Aegis ships and development of ACS, and also its feature.

High blood pressure (HTN) is a condition in which blood pressure is kept higher than normal. Blood pressure trait measures systolic blood pressure (SBP) which is the highest pressure and diastolic blood pressure (DBP) which is the lowest blood pressure. Pulse pressure (PP) is the difference between systolic and diastolic blood pressure. Hypertension is known as a disease caused by the interaction of the environment and genetic factors. To date, studies have been conducted to find genes associated with hypertension. Genome-Wide Association Study (GWAS) analysis using European data from the UK Biobank reported new 535 loci were associated with blood pressure trait. Among them, 12 genes have been reported to have a significant correlation with SBP, DBP and PP. In the study, 12 genes polymorphisms were extracted based on KARE (Korean association resource) and then we performed linear regression of blood pressure trait. As a result, 6 SNPs of the 3 genes (rs12355413 and rs11006736 of ARMC4, rs2290883, rs2290884 and rs11039014 of LRP4, rs7234941 of BCL2) showed statistically significant correlation (P<0.05) with blood pressure trait. Of the 3 genes, 6 SNPs in 2 genes (rs9651357, rs12355413, rs11006736, rs1889522 of ARMC4 and rs4987774, rs7234941 of BCL2) showed significant correlation with hypertension. These results suggest that genetic polymorphisms of ARMC4, LRP4 and BCL2 genes are associated with blood pressure traits and hypertension in Korean population. Moreover, we expected to help understand the pathogenesis of hypertension.
