Synthesis of a new class of triphenylamine-containing poly(ether-imide)s for electrochromic applications

Journal of Polymer Science Part A Polymer Chemistry (2013)

Sheng‐Huei Hsiao Pei‐Chi Chang Huimin Wang Yu‐Ruei Kung Tzong‐Ming Lee

A novel triphenylamine (TPA)-containing bis(ether anhydride) monomer, namely 4,4′-bis(3,4-dicarboxyphenoxy)triphenylamine dianhydride, was synthesized and reacted with various aromatic diamines leading to a series of new poly(ether-imide)s (PEI). Most of these PEIs were soluble in organic solvents and could be easily solution cast into flexible and strong films. The polymer films exhibited good thermal stability with glass-transition temperatures in the range 211–299 °C. The polymer films exhibited reversible electrochemical processes and stable color changes (from transparent to navy blue) with high coloration efficiency and contrast ratio upon electro-oxidation. During the electrochemical oxidation process, a crosslinked polymer structure was developed due to the coupling reaction between the TPA radical cation moieties in the polymer chains. These polymers can be used to fabricate electrochromic devices with high coloration efficiency, high redox stability, and fast response time. © 2013 Wiley Periodicals, Inc. J. Polym.

Mean Wind Speed Comparison and Wind Farm Energy Prediction at Chang-Hua Offshore (Taiwan)

Meharkumar Barapati Jiun‐Jih Miau Pei‐Chi Chang

Taiwan developing offshore wind power to promote green energy and self-electricity production. In this study, a Light Detection and Ranging (Lidar) was set up at Chang-Hua development zone one on the sea and 10km away from the seashore. At Lidar location, WRF (3.33km & 2km grid lengths) model and WAsP were used to simulate the wind speed at various elevations. Three days mean wind speed of simulated results were compared with Lidar data. From the four wind data sets, developed five different comparisons to find an error% and R-Squared values. Comparison between WAsP and Floating Lidar was shown good consistency. Lukang meteorological station 10 years wind observations at 5m height were used for wind farm energy predictions. The yearly variation of energy predictions of traditional and TGC wind farm layouts are compared under purely neutral and stable condition. The one-year cycle average surface heat flux over the Taiwan Strait is negative (-72.5 (W/m2) and 157.13 STD), which represents stable condition. At stable condition TGC (92.39%) and 600(92.44%), wind farms were shown higher efficiency. The Fuhai met mast wind data was used to estimate roughness length and power law exponent. The average roughness lengths are very small and unstable atmosphere.

Factors associated with intensiveness of use of child preventive health services in Taiwan: a comparative study between cross-cultural immigrant families and native-born families

Ethnicity and Health (2012)

Su-Chen Chien Yen‐Po Yeh Jyun-Yi Wu Chun-Hsiu Lin Pei‐Chi Chang

To compare intensiveness of use of child preventive health services (CPHS) between cross-cultural immigrant families and native-born families in Taiwan and to explore factors associated with differences in intensiveness of CPHS use.Cross-cultural immigrant families were defined as families where the mother was an immigrant from another southeast Asian country. In native-born families, both parents were Taiwanese-born. Data were collected from 318 immigrant mothers and 340 native-born mothers of children aged 7 years or younger in a cross-sectional survey in central Taiwan. A social determinants framework of health inequities was constructed, and ordinal logistic regression models were used to examine the effect of four domains of intermediary determinants on the relationship between family type and underuse of CPHS: CPHS-related factors, medical-related factors, maternal acculturation factors, and sociodemographic/socioeconomic characteristics.Cross-cultural immigrant families were less likely to intensively use CPHS than native-born families. This difference appeared to be mediated by the greater likelihood of having an older child or a lower educated father in cross-cultural families.Findings of this study highlight the importance of promoting health behaviors and combating health inequities and social inequalities for cross-cultural immigrant families in Taiwan from a sociodemographic/socioeconomic and political context.

A mathematical programming approach to supply chain models with fuzzy parameters

Engineering Optimization (2006)

Shih‐Pin Chen Pei‐Chi Chang

Supply chain (SC) models play an important role in supply chain management (SCM) for reducing costs and finding better ways to create and deliver value to customers. An approach to deriving the membership function of the fuzzy minimum total cost of the multi-product, multi-echelon, and multi-period SC model with fuzzy parameters is proposed in this article. On the basis of α-cut representation and the extension principle, a pair of mathematical programs are formulated to calculate the lower and upper bounds of the fuzzy minimum total cost at possibility level α. The membership function of the fuzzy minimum total cost is constructed by enumerating different values of α. To demonstrate the validity of the proposed procedure, a four-echelon five-period SC model with fuzzy parameters is solved successfully. Since the objective value is expressed by membership functions rather than by crisp values, they completely conserve the fuzziness of input information when some of the SC data are ambiguous. Thus the proposed approach can represent SCs with fuzzy parameters more accurately, and more information is provided for designing SCs in real-world applications.

Synthesis and electrochromic properties of aromatic polyetherimides based on a triphenylamine‐dietheramine monomer

Journal of Polymer Science Part A Polymer Chemistry (2013)

Sheng‐Huei Hsiao Huimin Wang Pei‐Chi Chang Yu‐Ruei Kung Tzong‐Ming Lee

ABSTRACT A series of electroactive polyetherimides (PEIs) with triphenylamine (TPA) units were prepared from the polycondensation reactions of 4,4′‐bis( p ‐aminophenoxy)triphenylamine with aromatic tetracarboxylic dianhydrides via a conventional two‐step technique. The PEIs showed high thermal stability, with glass‐transition temperatures of 234–282 °C and decomposition temperatures in excess of 500 °C. They showed well‐defined and reversible redox couples during both p ‐ and n ‐doping processes, together with multielectrochromic behaviors. These polymers exhibited enhanced redox‐stability and electrochromic performance as compared with the corresponding analogs without the phenoxy spacer between the TPA and imide units. © 2013 Wiley Periodicals, Inc.

The Significant Predictors for Breast, Cervical, Colorectal, or Oral Cancer Screening Intention and Behavior in Taiwan

Cancer Nursing (2022)

Hsiu‐Chen Huang Pei‐Chi Chang Sin-Fong Li Cing-Ya Wang Wan‐Ting Huang

Cancer screening can improve outcomes in patients with cancer. Accordingly, under the direction of the National Health Insurance program, the Taiwan government conducts screenings for breast cancer, cervical cancer, oral cancer, and colorectal cancer.The aim of this study was to identify the primary predictors of cancer screening intention and behavior at 1 and 6 months after patients are provided information and an invitation by telephone to attend cancer screenings.In this prospective longitudinal study, 339 participants meeting the screening criteria were recruited. At baseline, telephone interviews were used to collect information on demographic characteristics, exercise and smoking habits, family cancer history, screening beliefs, and screening intention. Screening behavior was followed up at 1 and 6 months after the telephone interviews.At baseline, 87.02% of the participants intended to undergo screening, and 31.86% and 63.42% had undergone screening after 1 and 6 months, respectively. The predictors of screening intention were awareness of the screening policy, willingness to learn about screening, and believing in the health benefits of screening. The predictor of screening behavior after 1 month was screening intention at baseline, and the predictors of behavior after 6 months were screening intention, marital status, and belief that cancer is a hereditary disease.Adults with screening intention tended to undergo cancer screenings.The use of strategies based on screening intention, beliefs, and information can be used to improve participation in cancer screening in Taiwan.
