Applying Information Technology (IT) in practical engineering has become one of the most important issues in the past few decades, especially on internal solitary wave, intelligent robot interaction, artificial intelligence, fuzzy Lyapunov, tension leg platform (TLP), consumer and service quality. Other than affecting the traditional teaching mode or increasing the inter-relation with users, IT can also be connected with the current society by collecting the latest information from the internet. It is apparently a fashion-catching-up technology. Therefore, the learning of how to use IT facilities is becoming one of engineers' skills nowadays. In addition to studying how well engineers learn to operate IT facilities and apply them into teaching, how engineers' general capacity of information effects the results of learning IT are also discussed. This research introduces the "Combined TAM and TPB mode," to understand the situation of engineers using IT facilities.

Electrochemical Behavior and Protective Property of Al-containing Zinc-Rich Paints

Chen, Wen-Ben,Chen, Peter,Chen, Hunz-Yin,Wu, Chung-Min,Tsai, Wen-Ta 한국부식방식학회 2002 Corrosion Science and Technology Vol.31 No.3

The effect of Al addition on the corrosion performance of zinc-rich paints (ZRP) was investigated. Both electrochemical measurement and salt spray test were employed to evaluate the corrosion performance of ZRP with or without Al addition. The Al content as percentage of the total metallic components in the ZRP, investigated in this study, varied from 0 to 75wt%. The experimental results showed that protective nature of ZRP altered from cathodic protection to barrier former as the Al content was increased beyond 20wt%. The results from salt spray tests also revealed that the corrosion products were modified with the presence of aluminum oxide in the Al-containing ZRP. The amount of zinc white on the painted steel decreased as the Al content in the ZRP increased. The protectiveness, in terms of the time of red rust formation and cathodic protection, was reduced as the Al content was higher than 20wt%.

Wu, Wen-Chung,Chen, Ching-Yi,Tian, Yanqing,Jang, Sei-Hum,Hong, Yuning,Liu, Yang,Hu, Rongrong,Tang, Ben Zhong,Lee, Yi-Ting,Chen, Chin-Ti,Chen, Wen-Chang,Jen, Alex K.-Y. WILEY-VCH Verlag 2010 Advanced Functional Materials Vol.20 No.9

<P>Three amphiphilic block copolymers are employed to form polymeric micelles and function as nanocarriers to disperse hydrophobic aggregation-induced emission (AIE) dyes, 1,1,2,3,4,5-hexaphenylsilole (HPS) and/or bis(4-(N-(1-naphthyl) phenylamino)-phenyl)fumaronitrile (NPAFN), into aqueous solution for biological studies. Compared to their virtually non-emissive properties in organic solutions, the fluorescence intensity of these AIE dyes has increased significantly due to the spatial confinement that restricts intramolecular rotation of these dyes and their better compatibility in the hydrophobic core of polymeric micelles. The effect of the chemical structure of micelle cores on the photophysical properties of AIE dyes are investigated, and the fluorescence resonance energy transfer (FRET) from the green-emitting donor (HPS) to the red-emitting acceptor (NPAFN) is explored by co-encapsulating this FRET pair in the same micelle core. The highest fluorescence quantum yield (∼62%) could be achieved by encapsulating HPS aggregates in the micelles. Efficient energy transfer (>99%) and high amplification of emission (as high as 8 times) from the NPAFN acceptor could also be achieved by spatially confining the HPS/NPAFN FRET pair in the hydrophobic core of polymeric micelles. These micelles could be successfully internalized into the RAW 264.7 cells to demonstrate high-quality fluorescent images and cell viability due to improved quantum yield and reduced cytotoxicity.</P> <B>Graphic Abstract</B> <P>Highly efficient fluorescence probes are achieved through the encapsulation of aggregation-induced emission molecules, 1,1,2,3,4,5-hexaphenylsilole (HPS) and/or bis(4-(N-(1-naphthyl) phenylamino)-phenyl)fumaronitrile (NPAFN) in the core of polymeric micelles.

Kefang Lai,Li Long,Fang Yi,Jiaman Tang,Zhe Chen,Fagui Chen,Jianmeng Zhou,Wen Peng,Liting Zhang,Hu Li,Wenzhi Zhan,Ruchong Chen,Wei Luo,Qiaoli Chen,Kian Fan Chung,Nanshan Zhong 대한천식알레르기학회 2019 Allergy, Asthma & Immunology Research Vol.11 No.6

Purpose: An older female predominance has been reported among chronic cough patients in Western countries, which is considered to be associated with a higher cough sensitivity in females. However, the characteristics of Chinese chronic cough patients remain unclear. This study aimed to explore the age and sex distribution as well as their relationship with cough reflex sensitivity to capsaicin in Chinese chronic cough patients. Methods: We analyzed the demographic features of 1,882 consecutive chronic cough patients who attended our cough clinic in Guangzhou, China. Cough sensitivity to capsaicin, which was defined as the lowest concentration of capsaicin causing 5 coughs or more (C5), was measured in 539 of the 1,882 patients and 68 healthy volunteers. Results: The mean age of the patients was 43.0 ± 13.7 years and patients aged <50 years accounted for more than two-thirds of the study population. Around 87% of the patients were never-smokers. The proportion of females (51.5%) was almost equal to that of males (48.5%). The pattern of the age and sex distribution was consistently reflected within most common causes of chronic cough, while a female predominance was shown in patients with coughvariant asthma and patients aged ≥50 years. Female patients had higher cough sensitivity to capsaicin than male patients (log C5: 1.58 ± 0.84 vs. 2.04 ± 0.84 μmol/L, P = 0.001), and patients aged ≥50 years had higher cough sensitivity to capsaicin than patients aged <50 years. Conclusions: In China, patients with chronic cough have a roughly equal sex distribution and a middle-aged predominance, irrespective of a higher cough sensitivity to capsaicin in females and older patients.

An Empirical Study on the Correlation among Innovative Strategies, Motivation, Level of Implementing Innovative Activities and Business Performance in Taiwan's High-tech Manufacturers

Chung, Yi-Chan,Hsu, Yao-Wen,Chiu, Chung-Ching,Chen, Ching-Piao,Tsai, Chih-Hung The Korean Society for Quality Management 2008 The Asian Journal on Quality Vol.9 No.3

This study explores the influence of Taiwan's high-tech manufacturers' innovative strategy and innovation motivation concerning the implementation of innovative activities, as well as the influence of innovative activities implementation on business performance. The two intermediate variables, industry group and enterprise scale are also considered. Through a review of the relevant literature, a theoretical model of the influence relationship is developed, while an empirical analysis is simultaneously conducted on Taiwan's high-tech manufacturers. The research result shows that the internal driving force of innovative activities has a significant impact on the level of implementing technological innovative activities and cultural innovative activities. The external driving force of innovative activities has a significant impact on the level of implementing market innovative activities and management innovative activities. Companies adopting self-developed technology and purchased as well as self-developed technology strategies, perform better than those adopting purchased new technology or those with neither purchased nor self-developed technology strategies, at implementing technological innovative activities and cultural innovative activities. The level of implementing innovative activities has a significant influence on business performance (cost reduction and product/service differentiation). For the intermediate variables of "industry group" and "enterprise scale", it is proven in this study that they have no significant influence on the level of innovative activity implementation or business performance.

<P>Electrostatic discharge (ESD) performance of N-type double-gated Si nanowire (NW) thin-film transistors is investigated, for the first time, using the transmission line pulsing technique. The ESD robustness of these devices depends on the NW dimension, number of channels, plasma treatment, and layout topology. The failure currents, leakage currents, and on-state resistances are characterized, and possible ESD protection applications of these devices for future NW field-effect-transistor-based integrated circuits are also discussed.</P>

Rheinheimera aquatica sp. nov., Antimicrobial Activity-Producing Bacterium Isolated from Freshwater Culture Pond

( Wen Ming Chen ),( Yi Lin Chang ),( Chung Young Chiu ),( Yi Sheu Shih ) 한국미생물 · 생명공학회 2010 Journal of microbiology and biotechnology Vol.20 No.10

A bacterial strain designated GR5T, previously isolated from a freshwater culture pond in Taiwan while screening for bacteria for antimicrobial compounds, was characterized using a polyphasic taxonomic approach. Strain GR5T was found to be Gram-negative, aerobic, greenish-yellow colored, rod-shaped, and motile by means of a single polar flagellum. Growth occurred at 10-40oC (optimum, 35oC), pH 7.0-8.0 (optimum pH 8.0), and with 0-2.0% NaCl (optimum, 0.5-1.0%). The major fatty acids were C16:1ω7c (36.3%), C16:0 (16.6%), C12:0 3-OH (12.5%), and C18:1ω7c (9.1%). The major respiratory quinone was Q-8, and the DNA G+C content of the genomic DNA was 51.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain GR5T belongs to the genus Rheinheimera, where its most closely related neighbors are Rheinheimera texasensis A62-14BT and Rheinheimera tangshanensis JA3-B52T with sequence similarities of 98.1% and 97.5%, respectively, and the sequence similarities to any other recognized species within Gammaproteobacteria are less than 96.5%. The mean level of DNA-DNA relatedness between strain GR5 T and R. texasensis A62-14BT, the strain most closely related to the isolate, was 26.5±7.6%. Therefore, based on the phylogenetic and phenotypic data, strain GR5T should be classified as a novel species, for which the name Rheinheimera aquatica sp. nov. is proposed. The type strain is GR5T (=BCRC 80081T= LMG 25379T).

Association of a Single Nucleotide Polymorphism in the 5'-Flanking Region of Porcine HSP70.2 with Backfat Thickness in Duroc Breed

Chen, Ming-Yu,Huang, San-Yuan,Lin, En-Chung,Hseu, Tzong-Hsiung,Lee, Wen-Chuan Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.1

Higher environmental temperature affects the economic performance of pigs. Heat shock protein 70 has been shown to play an important role in thermoresistance. The purpose of this study was to assess the effect of a single nucleotide polymorphism in the 5'-flanking region of porcine HSP70.2 on growth performance in Taiwanese Duroc. The genotype of this nt 393 polymorphic site could be verified by digestion with Bsa WI restriction enzyme of a PCR product. Pigs with TT and TC genotypes have thinner backfats than those with CC type (p<0.05). The result suggested that the polymorphic Bsa WI site in the 5'flanking region of porcine HSP70.2 may be used as a marker for the early selection of ultrasonic backfat thickness in Duroc pigs.
