Development of IGZO TFTs and Their Applications to Next-Generation Flat-Panel Displays
Hsing-Hung Hsieh,Hsiung-Hsing Lu,Hung-Che Ting,Ching-Sang Chuang,Chia-Yu Chen,Yusin Lin 한국정보디스플레이학회 2010 Journal of information display Vol.11 No.4
Organic light-emitting devices (OLEDs) have shown superior characteristics and are expected to dominate the nextgeneration flat-panel displays. Active-matrix organic light-emitting diode (AMOLED) displays, however, have stringent demands on the performance of the backplane. In this paper, the development of thin-film transistors (TFTs) based on indium gallium zinc oxide (IGZO) on both Gen 1 and 6 glasses, and their decent characteristics, which meet the AMOLED requirements,are shown. Further, several display prototypes (e.g., 2.4” AMOLED, 2.4” transparent AMOLED, and 32” AMLCD) using IGZO TFTs are demonstrated to confirm that they can indeed be strong candidates for the next-generation TFT technology not only of AMOLED but also of AMLCD (active-matrix liquid crystal display)

혼합 코풀라 모형은 대만 주식시장에서 외국계 기관투자가, 뮤추얼펀드 및 딜러의 극단수익률과 주식거래회전율 간의 관계를 연구하기 위해 사용되었다. 본 연구에서 는 극단적인 투자손실이 발생한 상황에서의 거래증가량을 연구하기 위한 변환된 함 수가 기재되었다. 실증결과 딜러는 극심한 손실 혹은 극심한 이익이 발생한 기간 모 두에서 가장 높은 거래량 증가를 나타내고 있다. 외국계 기관투자가와 비교했을 때, 뮤추얼펀드는 이익이 극대화되는 기간에 높은 거래량 증가 상태를 보였다. 이와 반 대로 뮤추얼펀드 비교했을 때 외국계 기관투자가는 극심한 투자손실이 발생되는 경 우에 높은 거래량 증가를 보였다. 극심한 주식수익률은 거래증가량에 비대칭적인 영 향을 끼치는 것을 확인할 수 있었다. Mixture copula models are used to study the relationships of extreme return and stock turnover rates of the foreign institutional investors, mutual funds and dealers in Taiwan. A transformation function is introduced in this paper to study the trading volume increment during extreme negative return condition. The results show that dealer has the highest trading volume increases both during extreme positive return and negative return periods. Comparing with foreign institutional investor, mutual fund has the higher trading increase during extreme positive return period. Comparing with mutual fund, foreign institutional investor has higher trading increase during extreme negative return period. The extreme stock market return has asymmetric impacts on the trading volume increment.

<P><B>Abstract</B></P> <P>Climate change gives rise to rapid degradation of rural soils in sloping subtropical and tropical areas and might further threaten environmental sustainability. In this study, we conducted an integrated evaluation of the effects of wood biochar (WB) application mixed with a green waste dreg compost (GWC) on runoff quality, soil losses, and agricultural productivity for a highly weathered tropical soil. A conventional agriculture method, in which soils are treated with anionic polyacrylamide (PAM), was also conducted for comparison. The amounts of runoff and soil loss, and nutrient retention were evaluated a year after WB application. Soil fertility was also investigated through a year pot experiment with rape (<I>Brassica campestris</I> L.) cultivation. Our results showed that the WB application not only effectively increased soil pH, soil organic carbon (SOC) and exchangeable K<SUP>+</SUP> but also increased the production of rape plants. Significant reduction of runoff and the increases of inorganic nitrogen (IN) and total phosphorus (TP) were found in the WB-treated soil. Compared to the control, the co-application of WB and GWC, particularly for the WB at 4%, decreased runoff by 16.8%, soil loss by 25%, and IN loss (via runoff) by 41.8%. Meanwhile, compared to the control and PAM treatments, the co-application of WB and GWC improved soil acidity and the contents of SOC, IN, TP, and exchangeable K<SUP>+</SUP>. The co-application of WB and GWC could be an alternative agricultural strategy to obtain benefits to agricultural productivity and environmental sustainability.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Co-applying biochar and compost notably reduced runoff and soil loss by 16%–25% in a tropical soil. </LI> <LI> In-situ biochar applying increased inorganic N, available P and K by 1.5–2.5 times in slopelands. </LI> <LI> Crop productivity was enhanced by biochar applying 1.5–2 times at least in a tropical slopeland. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Background/Aims Both sexual and physical abuse history have been reported to be associated with irritable bowel syndrome (IBS) in Western countries. The impact of abuse history in IBS patients in Asia remains unclear. We aim to determine the prevalence of abuse history, its associated psychological profiles, and sleep problems among IBS patients in Taiwan. Methods In total, 194 Rome III-defined IBS patients were invited to participate. Age- and sex- matched healthy carriers of chronic hepatitis B or hepatitis C without chronic abdominal symptoms were identified as disease-controls. We administered a validated questionnaire to evaluate bowel symptoms, physical/sexual abuse history, anxiety/depression (Hospital Anxiety and Depression Scale [HADS]), and sleep quality. Results IBS patients had a significantly higher prevalence of sexual abuse history than the disease-control group both before (16.5% vs 6.7%, P < 0.05) and after (16.0% vs 6.6%, P < 0.05) adolescence. These significant differences were mainly observed in women (13.4% vs 3.4%, P < 0.05). No difference was noted in history of physical abuse between the 2 groups. IBS patients with a history of sexual abuse had significantly higher HADS scores and higher frequencies of sleep difficulty than those without. Conclusions In Taiwan, sexual abuse history was more prevalent in female IBS patients than controls. Sexual abuse history may contribute to higher anxiety/depression levels and sleep difficulties, which are commonly experienced in IBS patients. In Asia, abuse history should be obtained when approaching IBS patients to facilitate better management. (J Neurogastroenterol Motil 2018;24:79-86)
