In countries with severe gun regulations, soldiers and police officers are commonly attacked by sharp weapons. The current personal protective equipment is too heavy, and therefore, in this study, mechanically strong Kevlar® fibers,nylon fibers, and Low-melting-point polyester (LMPET) fibers are needle punched to make thin, light, and comfortablenonwoven fabrics. Hot-baking and hot-pressing heat treatments are used for thermal bonding fibers, which subsequentlygenerate a dense and rigid surface because nonwoven fabrics are subjected to damaged structure by needle punch or aslippery state due to the fibers’ properties. The results of the air permeability, tensile strength, and quasi-static stab resistancetestings verify that the dense surface is correlated with hot-pressing heat treatment.

People have increasingly rising health consciousness in recent years and researchers are thus devoted themselvesto develop multi-functional textile products. In this study, stainless steel (SS) filaments are used for electromagnetic shieldingeffectiveness (EMSE) while polypropylene (PP) filaments are used for ultraviolet resistance and good mechanical properties. Spinning and weaving continuous formation techniques are employed to produce wrapped yarns with SS and PP filaments,after which a weaving process is employed for the preparation of SS/PP woven fabrics. The woven fabrics are tested forEMSE and UV resistance, examining the effect of the lamination-layer numbers and lamination-layer angles. Test resultsshow that the optimal EMSE and UV resistance occur when SS/PP woven fabrics are laminated with two layers at 90 °. Notonly focus on the mechanical performance, the proposed woven fabrics with good EMSE, UV resistance, and a light weight,and are good candidate for a variety of application as required. The proposed UV resistance and EMSE woven fabricssignificantly increase the additional values of traditional textiles.

Background: Medical staff may have difficulties in using conventional medicine to manage symptoms among terminally ill patients, including adverse effects of the treatment. Traditional Chinese medicine (TCM) is regarded as a complementary or alternative medicine, and has been increasingly used in the field of palliative medicine in recent years. This study aimed to investigate the experiences of and attitudes toward using TCM among palliative care professionals, and to provide preliminary information about its use in palliative care. Methods: This was a cross-sectional survey study conducted in eight inpatient hospice wards in Taiwan between December 2014 and February 2016. The questionnaire was self-administered, and was analyzed with descriptive statistics including Pearson’s Chi-square test and Fisher’s exact test. Results: A total of 251 palliative care professionals responded to the questionnaire, of whom 89.7% and 88.9% believed that the use of TCM could improve the physical symptoms and quality of life in terminally ill patients, respectively. Overall, 59.8%, of respondents suggested that TCM had rare side effects, and 58.2% were worried that TCM could affect the liver and kidney function of patients. In total, 89.7% and 88.0% of professionals agreed there were no suitable clinical practice guidelines and educational programs, respectively, for TCM use in palliative care. Conclusions: Most of the respondents agreed there was insufficient knowledge, skills-training, and continuing education on the use of TCM in terminally ill patients in Taiwan. These results show that to address patient safety considerations, guidelines about use of TCM in palliative care should be established.

As the number of network devices increases rapidly, it becomes more and more difficult to defend network attacks. Large-scaled attacks, such as SYN flooding, may lead to heavy burden to the switches as well as the controller in a software defined network (SDN). In this paper, we investigate the SYN flooding and Address Resolution Protocol (ARP) spoofing attacks in SDN, and then propose mechanisms to address these two attacks. We also present a new scheme to detect SYN flooding by using only a few forwarding rules. Moreover, we utilize the Programming Protocol-independent Packet Processors (P4) technique to mitigate the burden of the controller.

As described in this article, 4,40-bis(chloromethyl)biphenyl was obtained in 85% excellent yield by chloromethylation of biphenyl catalyzed by the recyclable temperature-dependant phase-separation system that comprised the dicationic acidic ionic liquid PEG1000-DAIL and methylcyclohexane under homogeneous catalysis in aqueous media. Compared to other synthetic methods, the novel method not only enhanced the yield, but also made the operating units easy workup. The mechanism of chloromethylation reaction and the process of catalysis in the thermoregulated ionic liquid bi-phase system were proposed.

Lin, Tzu-Yang,Hsu, Yu-Ting,Lan, Wen-How,Huang, Chien-Jung,Chen, Lung-Chien,Huang, Yu-Hsuan,Lin, Jia-Ching,Chang, Kuo-Jen,Lin, Wen-Jen,Huang, Kai-Feng Techno-Press 2015 Advances in nano research Vol.3 No.3
The unintentionally doped and bismuth (Bi) doped zinc oxide (ZnO) films were prepared by spray pyrolysis at $450^{\circ}C$ with zinc acetate and bismuth nitrate precursor. The n-type conduction with concentration $6.13{\times}10^{16}cm^{-3}$ can be observed for the unintentionally doped ZnO. With the increasing of bismuth nitrate concentration in precursor, the p-type conduction can be observed. The p-type concentration $4.44{\times}10^{17}cm^{-3}$ can be achieved for the film with the Bi/Zn atomic ratio 5% in the precursor. The photoluminescence spectroscopy with HeCd laser light source was studied for films with different Bi doping. The photocatalytic activity for the unintentionally doped and Bi-doped ZnO films was studied through the photodegradation of Congo red under UV light illumination. The effects of different Bi contents on photocatalytic activity are studied and discussed. Results show that appropriate Bi doping in ZnO can increase photocatalytic activity.

Background: Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. Materials and Methods: This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). Results: A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (p<0.001), poor performance(p<0.001), changes in medical condition (p<0.001), timing of case manager contact (p=.026), the methods by which case manager contact patients (p<0.001) and the frequency that case managers contact patients (${\geq}10times$) (p=0.016). Conclusions: Cancer patients who refuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

In this study, the coating process is employed on metal wire to help improve the friction resistant property ofcarbon fibers, thereby provides more application feasibility. The yarn coating technique for reinforcement and woven fabricprocess are used to produce carbon/stainless steel/polyester/polypropylene/acrylic (CSPPA) woven fabrics that arecharacterized with softness and a light weight. The constituent coated yarns exhibit good conductivity after being coated witha PP layer, and likewise strengthen the woven fabrics in terms of mechanical behavior of tensile strength, elongation, bendingtorsion, creep resistance, and wear-resistant properties. The test results indicate that in the woven process, samples retaingood morphology. Due to PP sheath, the tensile strength of woven fabrics increases from 23 MPa to 42 MPa. Although thelamination layer numbers does not improve the EMI SE of woven fabrics, the EMI SE still reaches over 40 dB. Themanufacturing design proposed in this study provides an innovative finishing for carbon fibers without affecting the intrinsicproperties, and provides a greater range of application for carbon fibers.
Synthesis of mesoporous SiO2 xerogel/chitosan mixed-matrix membranes for butanol dehydration
Yi-Feng Lin,Chang-Yu Wu,Ting-Yu Liu,Kun-Yi Andrew Lin,Kuo-Lun Tung,Tsair-Wang Chung 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.57 No.-
Novel mesoporous SiO2 xerogel/chitosan (CS) mixed-matrix membranes (MMMs) were successfully prepared by incorporating sol–gel synthesized SiO2 xerogels into glutaraldehyde (GA) cross-linked CS membranes. The effects of the SiO2 doping amount and the feed temperature on the performance of the separation of butanol and water was also investigated in this study. The 0.25 wt% SiO2 xerogel/CS MMMs possessed the best pervaporation performance and the largest PSI value of 1102 kg/m2h with a permeate flux of 736 g/m2h (Permeability of 3.25 × 10−5 g m m−2 h −1 Pa−1) and a separation factor of 1498 at a feed temperature of 50 °C. This PSI value is not only comparable but also exceeds that of other membranes reported in the literature. The separation factor and the flux of the SiO2 xerogel/CS MMMs in this study clearly exceed the upper limit of the previously reported MMMs. As a result, the as-prepared novel SiO2 xerogel/CS MMMs showed an improved performance during the butanol and water separation process, which raises the possibility of future pervaporation applications using this novel SiO2 xerogel/CS MMMs.
