Ping Feng,Xiao-li Wang,Chao Zhang,Wei Sun,Dai-min Chen 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.12

According to the mechanism of EMG signal, we know that the sacrificial electrical signal is with weak signal, low frequency, alternating, nonlinear and non-stationary characteristics. Nonlinear analysis includes higher order spectral analysis and fractal and chaos analysis.Chaos theory is one of the main parts of nonlinear science, and the electrical signal of the surface has a strong randomness, so we could consider the nonlinear analysis of EMG signals from the perspective of chaos. We mainly studied on the nonlinear analysis algorithm of EMG signal detailedly in this paper. Experiments show that,according to the quantitative analysis of several important parameters of rolling massage with chaos theory, we can measure objectively the action situation of related muscle groups in the operation course, then guide the professional massage students to understand the norms of operation in training of operation and help to lead their manipulation to the best power structure.

( Chao Wei Huang ),( Ko Chiao Yen ),( Chao Feng Yu ),( Ying Chen Lu ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

Many Gram-positive bacteria, particularly lactic acid bacteria, are known to secrete proteins that have antimicrobial activity. These proteins, known as bacteriocins, have been shown to display inhibitory activity against many pathogens. Use lactic acid bacteria fermented herb has many advantages, such as increase the extraction rate of herb, produce new active compounds, reduce waste etc. In this study, 270 strains of lactic acid bacteria were screened for bacteriocin producing ability, and Lactobacillus gasseri LYC400 was found to have highest bacteriocin activity. Lactobacillus gasseri LYC400 was used to ferment MRS broth with various concentration, 0, 2, 4, 6%, respectively, wild bitter melon (Momordica charantia Linn. var. abbreviata Ser.) powder. The fermentation broths were centrifuged and the supernatants were collected follow by protein extraction to analyze bacteriocin activity. The results showed wild bitter melon powder was able to support good growth of the lactic acid bacterium. The bacterial number, lactic acid concentration and the E. coli inhibition ability of protein extractions were positive correlated with bitter melon powder concentration. However, the Staphylococcus aureus inhibition ability of protein extractions were increased with 2, 4% bitter melon powder but decreased at 6% bitter melon powder. Fermentation wild bitter melon via Lactobacillus gasseri LYC400 increases its antibacterial activity with putative anti-diabetic activities may have great potential for health food.

Chao-Wei Tang,Yu-Ping Chen,How-Ji Chen,Chung-Ho Huang,Tsang-Hao Liu 사단법인 한국계산역학회 2013 Computers and Concrete, An International Journal Vol.11 No.1

High-performance concrete (HPC) usually has higher paste and lower coarse aggregate volumes than normal concrete. The lower aggregate content of HPC can affect the shear capacity of concrete members due to the formation of smooth fractured surfaces and the subsequent development of weak interface shear transfer. Therefore, an experimental investigation was conducted to study the shear strength and cracking behavior of full-scale reinforced beams made with low-cement-content high-performance concrete (LcHPC) as well as conventional HPC. A total of fourteen flexural reinforced concrete (RC) beams without shear reinforcements were tested under a two-point load until shear failure occurred. The primary design variables included the cement content, the shear span to effective depth ratio (a/d), and the tensile steel ratio (ρw). The results indicate that LcHPC beams show comparable behaviors in crack and ultimate shear strength as compared with conventional HPC beams. Overall, the shear strength of LcHPC beams was found to be larger than that of corresponding HPC beams, particularly for an a/d value of 1.5. In addition, the crack and ultimate shear strength increased as a/d decreased or ρw increased for both LcHPC beams and HPC beams. This investigation established that LcHPC is recommendable for structural concrete applications.

Chao-Jung Chen,Bi-Fang Lee,Wei-Jen Yao,Pei-Shan Wu,Wen-Chung Chen,Shu-Lin Peng,Nan-Tsing Chiu 대한영상의학회 2009 Korean Journal of Radiology Vol.10 No.2

We present here the case of a 40-year-old woman with a greater than 10 year prior history of bilateral breast silicone injection and saline bag implantation. Bilateral palpable breast nodules were observed, but the ultrasound scan was suboptimal and the magnetic resonance imaging showed no gadoliniumenhanced tumor. The 18F-FDG PET/CT scan showed a hypermetabolic nodule in the left breast with a 30% increase of 18F-FDG uptake on the delayed imaging, and this mimicked breast cancer. She underwent a left partial mastectomy and the pathology demonstrated a siliconoma.

Chen, Chao,Wang, Yumei,Su, Chun,Zhao, Xinqing,Li, Ming,Meng, Xiaowei,Jin, Yingyu,Yang, Seung-Hwan,Ma, Yushu,Wei, Wei,Joo-Won, Suh 한국응용생명화학회 2015 Applied Biological Chemistry (Appl Biol Chem) Vol.58 No.1

Passalora fulva (or Fulvia fulva) is the causal microorganism of tomato leaf mold, the outbreak of which occurs worldwide in greenhouse especially when humidity is high. However, studies on antifungal agents of P. fulva are still very limited. In this study, a marine-derived Streptomyces albidoflavus strain L131 showing potent inhibitory activities against P. fulva was identified and characterized. The active antifungal components were obtained, and studies on the antifungal mechanisms of the crude extract showed that the antifungal metabolites of L131 caused damage of hyphae and spore development, as well as plasma membrane of P. fulva. In addition, accumulation of endogenous reactive oxygen species of the leaf pathogen was also observed after treatment by culture extracts of L131. To our knowledge, this is the first report on the studies of the antifungal mechanisms against P. fulva, which benefit further development of biocontrol agent against tomato leaf mold disease.

Chao-bo Chen,Wei-dong Hu,Wan-wen Zhao,Yan-yan Gu,Hong-wei Hou,Zheng Pan 대한외과학회 2018 Annals of Surgical Treatment and Research(ASRT) Vol.94 No.3

Caroli disease is a rare congenital disorder characterized by nonobstructive dilatation of intrahepatic ducts. In cases with symptomatic intrahepatic manifestations, treatment should correspond to the type with hepatic resection for localized disease and transplantation for diffuse forms. If possible, complete resection of the cysts can cure the symptoms and avoid the risk of malignancy. A 66-year-old woman presented to Wuxi Xishan People's Hospital with recurrent intermittent upper quadrant abdominal pain. Further examinations suggested the diagnosis of Caroli disease limited to the left hepatic lobe. She underwent laparoscopic hepatectomy. Pathological examination confirmed the diagnosis of Caroli disease, and no malignancy was found. There were no immediate complications and no long-term complications after one and one-half years of follow-up. Laparoscopic hepatectomy could be a feasible, safe treatment option for localized Caroli disease

Crohn`s disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Hsiung, Chao Agnes,Lan, Qing,Hong, Yun-Chul,Chen, Chien-Jen,Hosgood III, H. Dean,Chang, I-Shou,Chatterjee, Nilanjan,Brennan, Paul,Wu, Chen,Zheng, Wei,Chang, Gee-Chen,Wu, Tangchun,Park, Jae Yong,Hsiao, Public Library of Science 2010 PLoS genetics Vol.6 No.8

<▼1><P>Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10<SUP>−7</SUP> or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed associations could be related to tobacco use, lung carcinogenesis, or both. Since most women in Asia do not smoke, we conducted a genome-wide association study of lung adenocarcinoma in never-smoking females (584 cases, 585 controls) among Han Chinese in Taiwan and found that the most significant association was for rs2736100 on chromosome 5p15.33 (p = 1.30×10<SUP>−11</SUP>). This finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls (p = 5.38×10<SUP>−11</SUP>). A pooled analysis achieved genome-wide significance for rs2736100. This SNP marker localizes to the <I>CLPTM1L</I>-<I>TERT</I> locus on chromosome 5p15.33 (p = 2.60×10<SUP>−20</SUP>, allelic risk = 1.54, 95% Confidence Interval (CI) 1.41–1.68). Risks for heterozygote and homozygote carriers of the minor allele were 1.62 (95% CI; 1.40–1.87), and 2.35 (95% CI: 1.95–2.83), respectively. In summary, our results show that genetic variation in the <I>CLPTM1L-TERT</I> locus of chromosome 5p15.33 is directly associated with the risk of lung cancer, most notably adenocarcinoma.</P></▼1><▼2><P><B>Author Summary</B></P><P>Worldwide, approximately 15% of lung cancer cases occur among nonsmokers. Genome-wide association studies (GWAS) of lung cancer conducted in populations of European background have identified three regions on chromosomes 5, 6, and 15 that harbor genetic variants that confer risk for lung cancer. Prior studies were conducted primarily in cigarette smokers, raising the possibility that the associations could be related to tobacco use, lung carcinogenesis, or both. A GWAS of lung cancer among never-smokers is an optimal setting to discover effects that are independent of smoking. Since most women in Asia do not smoke, we conducted a GWAS of lung adenocarcinoma among never-smoking females (584 cases, 585 controls) in Taiwan, and observed a region on chromosome 5 significantly associated with risk for lung cancer in never-smoking women. The finding was independently replicated in seven studies from East Asia totaling 1,164 lung adenocarcinomas and 1,736 controls. To our knowledge, this study is the first reported GWAS of lung cancer in East Asian women, and together with the replication studies represents the largest genetic association study in this population. The findings provide insight into the genetic contribution of common variants to lung carcinogenesis.</P></▼2>

Material Saving and Product Quality Improvement with the Visualization of Hot Runner Design in Injection Molding

Tzu-Chau Chen,Chao-Tsai Huang,Yan-Chen Chiu,Wei-Da Wang,Cheng-Li Hsu,Chen-Yang Lin,Lung-Wen Kao 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.

Runner system plays a very important role in injection molding process. A quality runner design is helpful in improving product qualities and saving material. However, traditional cold runner systems have certain inherent issues. Moreover, poor product cosmetics are commonly seen with the use of traditional cold runners. As a result, hot runner technology has been widely applied. On the other hand, It has been one of the green molding solutions for material/energy saving and clean environments. But the mechanism behind the hot runner system is too complicated to be fully understood. There exist some critical issues currently. As a result, the simulation technolgy is highly needed to examine hot runner designs before the real manufacturing. Through simulation analyses, designers and manufafctuers are able to catch the potential issues on their hot runner systems and revise their designs. Hot runner simulation technology helps with the investigations into the behavior in hot runner system. In this paper, a true 3D numerical method is proposed and applied to investigate the temperature behavior in a real hot runner system for PC material. The experiment is conducted and the simulating result is compared with that from the experiment for the validation purpose.
