The Strategy of Core Competencies in Open Innovation Process
Mei-Chu Chen 한국무역연구원 2013 The International Academy of Global Business and T Vol.9 No.2
Technology is one of the most useful resources for enterprises; it also can be called the weapon of enterprises. Therefore, most enterprises were performing research and developing technologies through self-sufficiency, and were always seeking how to improve their technology to keep their competitive position. However, because of globalization, competition among rivals is increasing, consumers` needs are changing, and it is hard for enterprises’ research and development to comply with market transformation. Therefore, many enterprises quit doing research and developing technologies though self-sufficiency. The meaning of self-sufficiency is reviewed and technical cooperation is one of the means which is requested to keep enterprises’ competitive position.

Lee, Mei-Chu,Hwang, Sen-Yuan,Chiou, Peter Wen-Shyg Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.11
The application of rumen undegradable intake protein (UIP) on lactating dairy goats was studied. Thirty 2-year-old lactating dairy goats were selected and assigned to dietary treatments begun from the third week to the fourth month postpartum. Experimental diets were formulated into three, low (32% CP), med (35% CP) and high (38% CP), iso-nitrogenous (16% CP) and iso-energetic ($NE_L$ 1.68 Mcal/kg) UIP levels. Results showed that feed intake was not significantly different among the treatment groups. The milk yield in the High UIP group (3.17 kg) was significantly higher than the med (2.95 kg) and low UIP (2.45 kg) groups (p<0.05). The milk compositions, milk fat, milk lactose and milk solids-non-fat (SNF) showed no significant differences among the three treatment groups. The milk protein however was significantly (p<0.05) lower in the low UIP than in the other treatment groups. The milk urea-N was significantly (p<0.05) higher in the low UIP than in the other treatment groups. The mean serum aspartate amino transferase (AST), urinary-N and total protein concentrations were significantly (p<0.05) lower in the high and the med UIP groups than in the low UIP group.

Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.

<P><B>Abstract</B></P> <P>Mesoporous Cu<SUB>2</SUB>O particles with different morphologies were synthesized via simple one-pot reactions. Effects of reducing agents, dispersant, template, and temperature on the <B>structure</B> of the prepared materials were investigated. Mesoporous flower-shaped Cu<SUB>2</SUB>O materials were obtained at 70℃ using glucose <B>as a reductant</B>. Different hollow microsphere shapes of Cu<SUB>2</SUB>O could be prepared at 40℃ using <B>another type of reductant, ascorbic acid</B>. The results indicated that the uniform morphology of synthesized Cu<SUB>2</SUB>O with mesopores presented a maximum specific surface area of 45.3m<SUP>2</SUP>/g. Furthermore, the as-prepared Cu<SUB>2</SUB>O particles showed good photodegradation efficiencies of methyl orange in the range of 86.0–93.7%, depending on their morphologies.</P>
Construction of antibacterial layer on polyvinylchloride three-channel hollow fiber membranes
Mei-Sheng Li,Ming-Xing Wang,Fei-Yue Wu,Xiao-Zhong Chu 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.39 No.-
The inner surfaces of polyvinylchloride (PVC) three-channel hollow fiber membranes were successfullymodified with poly(methacryloxylethyl benzyl dimethyl ammonium chloride) (PDMAE-BC) in a modulescale via remote plasma-induced surface graft polymerization method. After grafting a PDMAE-BC layer,the PVC surface hydrophilicity was improved greatly due to the introduction of large amounts of oxygenand nitrogen containing polar groups onto polymer backbone. This hydrophilicity improvement directlyleaded to a high pure water flux and a good antifouling property for the obtained PVC-PDMAE-BCmembrane module. Meanwhile, the inner surface morphologies of modified PVC membranes changedslightly and the surface structures were maintained well. The tensile strength, though deceased slightlyat the remote plasma-treated stage, showed no significant change during overall grafting process. Theobtained PVC-PDMAE-BC membrane module exhibited highly effective and stable antibacterialactivities against Escherichia coli. The antibacterial efficacy of PVC-PDMAE-BC membrane module withonly 6 fibers can achieve about 96.3% and could be further enhanced by increasing the packing density. The antibacterial membrane module may have great potential applications in actual wastewatertreatment and membrane bioreactor (MBR).

Objective: Altered event-related potential (ERP) performances have been noted in attention deficit hyperactivity disorder (ADHD) patients and reflect neurocognitive dysfunction. Whether these ERP alterations and correlated dysfunctions exist in healthy parents with ADHD offspring is worth exploring. Methods: Thirteen healthy parents with ADHD offspring and thirteen healthy controls matched for age, sex and years of education were recruited. The auditory oddball paradigm was used to evaluate the P300 wave complex of the ERP, and the Wechsler Adult Intelligence Scale-Revised, Wisconsin Card Sorting Test, and continuous performance test were used to measure neurocognitive performance. Results: Healthy parents with ADHD offspring had significantly longer auditory P300 latency at Fz than control group. However, no significant differences were found in cognitive performance. Conclusion: The presence of a subtle alteration in electro-neurophysiological activity without explicit neurocognitive dysfunction suggests potential candidate of biological marker for parents with ADHD offspring.
