Room-temperature flexible thin film transistor with high mobility
Hsiao-Hsuan Hsu,Chun-Yen Chang,Chun-Hu Cheng 한국물리학회 2013 Current Applied Physics Vol.13 No.7
We report a room-temperature and high-mobility InGaZnO thin-film transistor on flexible substrate. To gain both high gate capacitance and low leakage current, we adopt stacked dielectric of Y2O3/TiO2/Y2O3. This flexible IGZO TFT shows a low threshold voltage of 0.45 V, a small sub-threshold swing of 0.16 V/decade and very high field-effect mobility of 40 cm2/V. Such good performance is mainly contributed by improved gate stack structure and thickness modulation of IGZO channel that reduce the interface trap density without apparent mobility degradation.

Background: Dietary fat has been suggested to be the cause of various health issues. Obesity, hypertension,cardiovascular disease, diabetes, dyslipidemia, and kidney disease are known to be associatedwith a high-fat diet (HFD). Obesity and associated conditions, such as type 2 diabetes mellitus andnonalcoholic fatty liver disease (NAFLD), are currently a worldwide health problem. Few prospectivepharmaceutical therapies that directly target NAFLD are available at present. A Traditional ChineseMedicine, ginseng-plus-Bai-Hu-Tang (GBHT), is widely used by diabetic patients to control glucose levelor thirst. However, whether it has therapeutic effects on fat-induced hepatic steatosis and metabolicsyndrome remains unclear. Methods: This study was conducted to examine the therapeutic effect of GBHT on fat-induced obesity,hepatic steatosis, and insulin resistance in mice. Results: GBHT protected mice against HFD-induced body weight gain, hyperlipidemia, andhyperglycemia compared with mice that were not treated. GBHT inhibited the expansion of adiposetissue and adipocyte hypertrophy. No ectopic fat deposition was found in the livers of HFD mice treatedwith GBHT. In addition, glucose intolerance and insulin sensitivity in HFD mice was also improved byGBHT. Conclusion: GBHT prevents changes in lipid and carbohydrate metabolism in a HFD mouse model. Ourfindings provide evidence for the traditional use of GBHT as therapy for the management of metabolicsyndrome.

Background/AimsLaryngeal symptoms are largely treated with empiric proton pump inhibitor (PPI) therapy if no apparent pathology shown on ear, nose, and throat evaluation and reflux-related etiologies are suspected. However, treatment response remains unsatisfactory. This study aimed to investigate the clinical and physiological characteristics of patients with PPI-refractory laryngeal symptoms. MethodsPatients with persistent laryngeal symptoms despite PPI treatment for ≥ 8 weeks were recruited. A multidisciplinary evaluation comprising validated questionnaires for laryngeal symptoms (reflux symptom index [RSI]), gastroesophageal reflux disease symptoms, psychological comorbidity (5-item brief symptom rating scale [BSRS-5]) and sleep disturbance (Pittsburgh sleep quality index [PSQI]), esophagogastroduodenoscopy, ambulatory impedance-pH monitoring, and high-resolution impedance manometry were performed. Healthy asymptomatic individuals were also recruited for comparison of psychological morbidity and sleep disturbances. ResultsNinety-seven adult patients and 48 healthy volunteers were analyzed. The patients had markedly higher prevalence of psychological distress (52.6% vs 2.1%, P < 0.001) and sleep disturbance (82.5% vs 37.5%, P < 0.001) than the healthy volunteers. There were significant correlations between RSI and BSRS-5 scores, and between RSI and PSQI scores (r = 0.26, P = 0.010, and r = 0.29, P = 0.004, respectively). Fifty-eight patients had concurrent gastroesophageal reflux disease symptoms. They had more prominent sleep disturbances (89.7% vs 71.8%, P < 0.001) than those with laryngeal symptoms alone but similar reflux profiles and esophageal motility. ConclusionsPPI-refractory laryngeal symptoms are mostly associated with psychological comorbidities and sleep disturbances. Recognition of these psychosocial comorbidities may help optimize management in these patients.

With the advent of globalization and the accompanying rapid changes in economic environments, firms have gradually transformed their mode of operations from one based on the traditional good-dominant logic to one based on service-dominant logic. The emergence of service-dominant logic has resulted in the development of value co-creation, which refers to the process through which firms, suppliers, and customers all become involved in the discovery and creation of product value and create added value through even and reasonable distribution. Drawing upon the SDT theory, the current study has the following three research objectives. First, the current study investigated the influence of transformational leadership on employee-based value co-creation and the impact of transformational leadership on employees’ intrinsic motivation to further enhance their value co-creation. Second, this study sought to understand the mediating mechanisms between transformational leadership and employee-based value co-creation; financial and non-financial variables were used as the mediators to explore whether the financial incentive affects employees’ intrinsic motivational process with regard to the transformational leadership that leads to employees’ intrinsic motivation. Third, positive psychological capital was used as a mediator to examine whether it mediates the relationship between the financial perspective and value co-creation. Fourth, self-concordance was also adopted to examine whether self-concordance mediates the relationship between the financial perspective and value co-creation. We collected 513 survey responses from 81 teams in firms from diverse industries in Taiwan. The present study makes the following contributions. First, previous research related to leadership behavior primarily focused on the influences of leadership behaviors on employee attitudes and behaviors. Only a few studies addressed the impact of leadership on value co-creation. Drawing on the self-determination theory to build our research framework, our study contributes to the field by investigating how transformational leadership stimulates employee-based value co-creation. Second, the present study investigated the psychological mechanisms involved in the motivational process in the context of the ways in which transformational leadership facilitates changes in employee behavior, particularly for employees’ intrinsic motivation. Third, the present study proved that financial and non-financial incentives respectively mediated the relationship between transformational leadership and positive psychological capital. Additionally, both financial and non-financial incentives mediated the relationship between transformational leadership and self-concordance. These results suggest that both financial and non-financial incentives could be effective ways for transformational leaders to intrinsically motivate their employees. These findings are valuable contributions to the leadership studies field. Fourth, the present study adopted hierarchical linear modeling (HLM) to conduct a multi-level analysis of the relationship between transformational leadership and value co-creation.
A MULTI-HIERARCHICAL ANALYSIS OF ONLINE SERVICE RECOVERY
Tzu-En Lu,Yi-Hsuan Lee,Chan Hsiao,Jer-Wei Hsu 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07
This study incorporates brand equity and brand identity, two vital factors influencing customer-brand perception, to explore the process from service recovery to perceived justice. This study adopted HLM as the research framework because brand perception differs at various levels and adopting HLM allows us to precisely understand the influence of brand identity and brand equity on the relationship between service recovery and perceived justice. The contributions of this study are listed as follows: a) online service recovery can positively affect customer-perceived justice; b) brand equity at the organizational level can undermine the relationships that courtesy and compensation have with perceived justice; c) brand identity at the individual level can undermine the relationships that courtesy and compensation have with perceived justice; and d) using hierarchical linear modeling can precisely measure the relationship between organizations and customers; therefore, this method is innovative and can contribute to the research on online service recovery.

In this study, we report a resistive random access memory (RRAM) using trilayer SiOx/a-Si/TiOy film structure. The low switching energy of <10 pJ, highly uniform current distribution (<13% variation), fast 50-ns speed and stable cycling endurance for 106 cycles are simultaneously achieved in this RRAM device. Such good performance can be ascribed to the use of interface-engineered dielectric stack with 1D1R-like structure. The SiOx tunnel barrier in contact with top Ni electrode to form diode-like rectifying element not only lowers self-compliance switching currents, but also improves cycling endurance, which is favorable for the application of high-density 3D memory.
