Uniqueness of meromorphic solutions of a certain type of difference equations
Jun-Fan Chen,Shu-Qing Lin 대한수학회 2022 대한수학회보 Vol.59 No.4
In this paper, we study the uniqueness of two finite order transcendental meromorphic solutions $f(z)$ and $g(z)$ of the following complex difference equation $$A_{1}(z)f(z+1)+A_{0}(z)f(z)=F(z)e^{\alpha(z)}$$ when they share 0, $\infty$ CM, where $A_{1}(z),$ $A_{0}(z),$ $F(z)$ are non-zero polynomials, $\alpha(z)$ is a polynomial. Our result generalizes and complements some known results given recently by Cui and Chen, Li and Chen. Examples for the precision of our result are also supplied.

The collaborative teaching research was conducted in northern Taiwan’s Tayal indigenous tribe to practice a constructivist inquiry-based science project curriculum implementing place-based education for kindergarten children. Research participants included 2 classroom teachers and 15 young children. Entering the natural tribal context, the researcher collected data through field observations, interviews, and other documentation. Qualitative method was adopted to analyze research data. A bamboo project was implemented relating to children’s life experiences. Research findings reveal: (1) teachers and children managed to co-construct a science project curriculum based on local resources and Tayal traditional knowledge (2) children developed basic scientific concepts and knowledge about natural plants through the inquiry-based project curriculum and (3) teachers regarded their roles as being colearners with children and realized the importance of children’s active involvement in the constructivist inquiry-based teaching. The result can help to improve science teaching/learning for indigenous children by utilizing environmental resources as well as traditional knowledge in future education.

There is growing evidence that the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with increased risks of psychiatric sequelae. Depression, anxiety, cognitive impairments, sleep disturbance, and fatigue during and after the acute phase of COVID-19 are prevalent, long-lasting, and exerting negative consequences on well-being and imposing a huge burden on healthcare systems and society. This current review presented timely updates of clinical research findings, particularly focusing on the pathogenetic mechanisms underlying the neuropsychiatric sequelae, and identified potential key targets for developing effective treatment strategies for long COVID. In addition, we introduced the Formosa Long COVID Multicenter Study (FOCuS), which aims to apply the inflammation theory to the pathogenesis and the psychosocial and nutrition treatments of post-COVID depression and anxiety.

Smad4 is involved in cancer progression and metastasis. Using a pair of human syngeneic epithelial ovarian cancer cells with low (HO-8910) and high (HO-8910PM) metastatic abilities, we aimed to reveal the role of Smad4 in ovarian cancer metastasis in vitro. Smad4 was down-regulated in HO-8910PM cell line relative to HO-8910 by implicating Smad4 was probably a potential tumor suppressor gene for ovarian cancer. Re-expression of Smad4 decreased the migration ability and inhibited the invasion capacity of HO-8910PM, while promoted the cell adhesion capacity for HO-8910PM. The stable expression of Smad4 increased the expression of E-cadherin, reduced the expression of plasminogen activator inhibitor-1 (PAI-1) and slightly down-regulated the expression of VEGF. Smad4 suppresses human ovarian cancer cell metastasis potential through its effect on the expressions of PAI-1, E-cadherin and VEGF. Results from current work implicate Smad4 might suppress the invasion and metastasis of human ovarian tumor cells through a TGF-β/Smad-mediated pathway. [BMB reports 2010; 43(8): 554-560]

The development of a fermentation strategy for hyaluronic acid (HA) production by Streptococcus zooepidemicus ATCC 39920 has been explored. The specific HA productivity (YP/X) was affected by the medium carbon-tonitrogen (C/N) ratio rather than the specific growth rate of cells. Accordingly, HA fermentation should be performed in a balanced medium with an optimum C/N ratio of 2 : 1 in a batch culture. To improve the performance of the batch culture, the operation conditions for the fill-and-draw culture were investigated. It was found that the timing of medium exchange is critical for successfully performing fill-and-draw operations. Since streptococcal cells at the stationary phase might lose the capacity of HA synthesis, the displacement of the medium in a fill-and-draw culture should be started at the late exponential growth phase.

Based on social learning theory , this study investigates whether psychological capital mediates the ethical leadership- work engagement link and the ethical leadership-job satisfaction link. Again, it tests whether moral identity moderates the relationship between ethical leadership and psychological capital. With data collected from 177 public servants in Malawi, this study’s findings reveal that psychological capital fully mediates the relationship between ethical leadership and work engagement while it partially mediates the ethical leadership-job satisfaction link. Furthermore, the results reveal that moral identity moderates the relationship between ethical leadership and psychological capital. The study has important implications for practice especially in human resource management in developing and adopting practices that promote work engagement and job satisfaction among employees.

In this paper, we propose the Stancu type generalization of a kind of modified q-Gamma operators. We estimate the moments of these operators and give the basic convergence theorem. We also obtain the Voronovskaja type theorem. Furthermore, we obtain the local approximation, rate of convergence and weighted approximation for these operators.
