Yi-rong Ying,Ying Ye 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.11

Through the establishment of the capital flight model of asymmetric evolutionary game, this paper focuses on the study of game relationship among perpetrators, perpetrator assistants and government, and analyzes the evolutionary stable process under different conditions by three-dimensional figures. This paper also analyzes and compares features between the two parties’ model and the three parties’ model, connecting the two kinds of evolutionary games and providing a theoretic basis for a better understanding of the mechanism of capital flight and motivation of all groups. The result shows that by making use of expectation, government can control the ESS of capital flight groups by adjusting relative benefits and punishment in different regulation modes. It can also expand the strategy space that is in favor of capital control through the adjustment. In the end, this paper will propose policy suggestions for the control of capital flight according to the research findings above.

Advanced Parameter Identification for a Linear-Motor-Driven Motion System Using Disturbance Observer

Yi-Ren Pan,An-Chen Lee,Yi-Ti Shih,Rong-Hwang Horng 한국정밀공학회 2009 International Journal of Precision Engineering and Vol. No.

Disturbance observer (DOB) is generally introduced into motion control systems to eliminate undesired disturbances and plant uncertainty. The DOB is also used for system identification. This work presents a novel experimental identification algorithm using disturbance observer to identify inertia, viscous coefficient, and friction of linear-motor-driven motion system. A conventionally adopted algorithm for determining the inertia of the motion system based on orthogonal relations among system responses is modified and extended to estimate the viscous coefficient and the magnitude of Coulomb friction of the underlying system. The advantages of the proposed method are high convergence rate and only one experiment needed to evaluate the system parameters. The proposed algorithm is demonstrated to be workable by both simulation and experiment.

Yi-Ding Hu,Qi Xia,Rong-rong Hou,Yong Xia,Jian-yi Yan 국제구조공학회 2021 Smart Structures and Systems, An International Jou Vol.27 No.3

The development of image sensors enables the application of vision-based techniques to the non-contact displacement measurement of large-scale structures. The features of the physical targets are critical to the accuracy, stability and anti-interference of the displacement measurement results. In this study, a novel m-sequence target and the associated circular correlation processing technique are developed for real-time displacement measurement. The properties of the m-sequence as a pseudo-random sequence are introduced. The vision-based displacement calculation method is then derived from the correlation property of the m-sequence. The algorithms and measurement systems are integrated in the LabVIEW environment. To verify the anti-interference performance of the developed system, static and dynamic experimental tests are carried out with various forms of interference, such as partial occlusion, uneven illumination, out of focus and smoke effect. Experimental results indicate that the developed system cannot only accurately measure structural displacement, but also has outstanding antiinterference performance, even if 30% of the target is masked.

Effects of Material Properties and Fabric Structure Characteristics of Graduated Compression Stockings (GCS) on the Skin Pressure Distributions

Liu Rong,Kwok Yi-Lin,Li Yi,Lao Terence-T,Zhang Xin The Korean Fiber Society 2005 Fibers and polymers Vol.6 No.4

Graduated compression stockings (GCS) have been widely used for the prophylaxis and treatment of venous diseases. Their gradient pressure function largely related to their fabric structure and material properties. By combing fabric physical testing and wear trials, this study investigated the GCSs fabric structure and material properties at different locations along the stocking hoses, and quantitatively analyzed the effects of fabrics on skin pressure longitudinal and transverse distributions. We concluded that, Structural characteristics and material properties of stocking fabrics were not uniform along the hoses, but a gradual variation from ankle to thigh regions, which significantly influenced the corresponding skin pressure gradient distributions; Tensile (WT, EM) and shearing properties (G) generated most significant differences among ankle, knee and thigh regions along the stocking hose, which significantly influenced the skin pressure lognitudinal gradient distribution. More material indices generating significant gradual changes occurred in the fabric wale direction along stocking hose, meaning that materials properties in wale direction would exert more important impact on the skin pressure gradient performances. And, the greater tensibility and smoother surface of fabric in wale direction would contribute to put stocking on and off, and facilitate wearers' leg extension-flexion movements. The indices of WT and EM of stocking fabrics in series A have strong linear correlations with skin pressure lognitudinal distribution, which largely related to their better performances in gradual changes of material properties. Skin pressure applied by fabric with same material properties produced pronounced differences among four different directions around certain cross-sections of human leg, especially at the ankle region; and, the skin pressure magnitudes at ankle region were more easily influenced by the materials properties, which were considered to be largely related to the anatomic structure of human leg.

RNAi knock down of Tenebrio molitor myeloid differentiation factor 88 (MyD88) significantly reduces survival against the infection of Beauveria bassiana JEF-007

Mi Rong Lee,Yi-Ting Yang,Se Jin Lee,Jae Su Kim 한국응용곤충학회 2016 한국응용곤충학회 학술대회논문집 Vol.2016 No.04

Myeloid differentiation factor 88 (MyD88) is an intracellular adaptor protein involved in Toll signaling pathway. In this study, we monitored the response of 4 key genes of the insect immune system against Beauveria bassiana JEF-007 in Tenebrio molitor using RT-PCR. TmGPR, antimicrobial peptide Tenecin 1 and Tenecin 2 were up-regulated after fungal infection. To better understand the roles of Toll signaling pathway in mealworm immune system, TmGRP and TmMyD88 was knocked down by RNAi silencing. Target gene expressions were decreased at 2 days post-dsRNA injection, and dramatically reduced at 6 days post-dsRNA injection. Therefore, mealworms were compromised by B. bassiana JEF-007 at 6 days post-dsRNA injection. Silencing of the TmMyD88 and TmGRP resulted in reducing the resistance of the host to fungal infection. However, only dsTmMyD88 showed significant difference with dsEGFP by statistical analysis, which may be due to partial gene knock down of dsGRP. These results indicate that TmMyD88 is required in mealworms for survival against B. bassiana JEF-007.

Yue-Rong Liang,Shi-Cheng Ma,Xin-Qiang Zheng,Jing-Yi Xu,Ming-Yan Wu,Yi-Wen Luo,Xian-Yang Luo,Jian-Liang Lu 한국식품과학회 2011 Food Science and Biotechnology Vol.20 No.1

Three groups of spontaneously hypertensive rats were administered by gavage with distilled water (control group), low-dose green tea (LGT, 0.2 g/kg BW·day) and high-dose green tea (HGT, 1.0 g/kg BW·day) for 4 weeks,during which systolic blood pressure (SBP) was measured weekly by non-invasive tail-cuff method. At the end of experiment, left ventricular hypertrophy index (LHVI) and plasma biochemical indicators were determined, and ultrastructures of myocardium and aortic vascular smooth muscle cells were observed by transmission electron microscopy (TEM). The results show that green tea gavage suppressed the increase in SBP, along with decline in levels of plasma nitric oxide, aldosterone, malondialdehyde, and LHVI, but increased levels of plasma creatinine, calcitonin gene-related peptide, and glutathione peroxidase in a dose dependant manner. Green tea had no effect on plasma total cholesterol. TEM shows that green tea gavage protected mitochondria of left ventricular myocardium and aortic vascular smooth muscle cells from damage.

Effects of miR-152 on Cell Growth Inhibition, Motility Suppression and Apoptosis Induction in Hepatocellular Carcinoma Cells

Dang, Yi-Wu,Zeng, Jing,He, Rong-Quan,Rong, Min-Hua,Luo, Dian-Zhong,Chen, Gang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.12

Background: miR-152 is involved in the genesis and development of several malignancies. However, its role in HCC has not been fully clarified. The aim of this study was to investigate the clinicopathological significance of miR-152 and its effect on the malignant phenotype of HCC cells. Methods: miR-152 expression was detected using real-time quantitative RT-PCR in 89 pairs of HCC formalin-fixed paraffin-embedded and their adjacent tissues. Functionally, in vitro effects and mechanisms of action of miR-152 on proliferation, viability, caspase activity, apoptosis and motility were explored in HepG2, HepB3 and SNU449 cells, as assessed by spectrophotometry, fluorimetry, fluorescence microscopy, wound-healing and Western blotting, respectively. Results: miR-152 expression in HCC was downregulated remarkably compared to that in adjacent hepatic tissues. miR-152 levels in groups of advanced clinical stage, larger tumor size and positive HBV infection, were significantly lower than in other groups. A miR-152 mimic could suppress cell growth, inhibit cell motility and increase caspase activity and apoptosis in HCC cell lines. Furthermore, Western blotting showed that the miR-152 mimic downregulated Wnt-1, DNMT1, ERK1/2, AKT and TNFRS6B signaling. Intriguingly, inverse correlation of TNFRF6B and miR-152 expression was found in HCC and bioinformatics confirmed that TNFRF6B might be a target of miR-152. Conclusions: Underexpression of miR-152 plays a vital role in hepatocarcinogenesis and lack of miR-152 is related to the progression of HCC through deregulation of cell proliferation, motility and apoptosis. miR-152 may act as a tumor suppressor miRNA by also targeting TNFRSF6B and is therefore a potential candidate biomarker for HCC diagnosis, prognosis and molecular therapy.

A Three-dimensional Biomechanical Model for Numerical Simulation of Dynamic Pressure Functional Performances of Graduated Compression Stocking (GCS)

Liu, Rong,Kwok, Yi-Lin,Li, Yi,Lao, Terence-T,Zhang, Xin,Dai, Xiao-Qun The Korean Fiber Society 2006 Fibers and polymers Vol.7 No.4

The beneficial effects of graduated compression stockings (GCS) in prophylaxis and treatment of venous disorders of human lower extremity have been recognized. However, their pressure functional performances are variable and unstable in practical applications, and the exact mechanisms of action remain controversial. Direct surface pressure measurements and indirect material properties testing are not enough for fully understanding the interaction between stocking and leg. A three dimensional (3D) biomechanical mathematical model for numerically simulating the interaction between leg and GCS in dynamic wear was developed based on the actual geometry of the female leg obtained from 3D reconstruction of MR images and the real size and mechanical properties of the compression stocking prototype. The biomechanical solid leg model consists of bones and soft tissues, and an orthotropic shell model is built for the stocking hose. The dynamic putting-on process is simulated by defining the contact of finite relative sliding between the two objects. The surface pressure magnitude and distribution along the different height levels of the leg and stress profiles of stockings were simulated. As well, their dynamic alterations with time processing were quantitatively analyzed. Through validation, the simulated results showed a reasonable agreement with the experimental measurements, and the simulated pressure gradient distribution from the ankle to the thigh (100:67:30) accorded with the advised criterion by the European committee for standardization. The developed model can be used to predict and visualize the dynamic pressure and stress performances exerted by compression stocking in wear, and to optimize the material mechanical properties in stocking design, thus, helping us understand mechanisms of compression action and improving medical functions of GCS.

( Luo Yi ),( Guo Yi Zhang ),( Zhen Zhu ),( Xiao Hui Wang ),( Wei Ran ),( Qi Rong Shen ) 한국미생물생명공학회(구 한국산업미생물학회) 2013 한국미생물·생명공학회지 Vol.41 No.1

The nutritional requirements for the maximum production of lipopeptides by Bacillus subtilis N7 (B. subtilis N7) were investigated and optimized using response surface methodology (RSM) under shake flask fermentation. A one-factor-at-a time experimental setup was used to screen carbon and nitrogen sources. A Plackett?Burman design (PBD) was employed to screen the most critical variables for lipopeptides production amongst ten nutritional elements. The central composite experimental design (CCD) was finally adopted to elucidate the composition of the fermentation medium. Statistical analyses (analysis of variance, ANOVA) of the results showed that KCl, MnSO4 and FeSO4·6H2O were important components and that their interactions were strong. Lipopeptide production was predicted to reach 709.87 mg/L after a 60 h incubation using an optimum fermentation medium composed of glucose 7.5 g/L, peanut oil 1.25 g/L, MgSO4 0.37 g/L, KH2PO4 0.75 g/L, monosodium glutamate 6.75 g/L, yeast extract and NH4Cl (5:3 w/w) 10 g/L, KCl 0.16 g/L, FeSO4·6H2O 0.24 mg/L, MnSO4 0.76 mg/L, and an initial pH of 7.0. Lipopeptide production (706.57 ± 3.70 mg/L) in the optimized medium confirmed the validity of the predicted model.
