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.
Malaysian Container Seaport-Hinterland Connectivity: Status, Challenges and Strategies
Shu-Ling CHEN,Jagan JEEVAN,Stephen CAHOON 한국해운물류학회 2016 The Asian journal of shipping and Logistics Vol.32 No.3
This paper adopts a qualitative methodology to assess the Malaysian container seaport-hinterland connectivity from the perspective of its physical properties. The findings reveal that although Malaysia’s major container seaports are connected to the hinterlands through road and rail transport, they are highly dependent on road. These seaports are also connected to inland freight facilities such as dry ports and ICDs, which are positioned as transit points to help connect exporters and importers in the hinterlands to seaports as well as facilitating regional and cross-border trades. This paper suggests that the quality of hinterland connectivity of Malaysian container seaports could be improved by implementing strategies which tackle the existing challenges including overcoming an extremely imbalanced modal split, insufficient rail capacity and limited train services, increasing road congestion and the limitations of space restriction in some inland facilities.
STANCU TYPE GENERALIZATION OF MODIFIED GAMMA OPERATORS BASED ON q-INTEGERS
Chen, Shu-Ni,Cheng, Wen-Tao,Zeng, Xiao-Ming Korean Mathematical Society 2017 대한수학회보 Vol.54 No.2
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.

Dnd (dead end) gene encodes an RNA binding protein and is specifically expressed in primordial germ cells (PGCs) as a vertebrate-specific component of the germ plasma throughout embryogenesis. By utilizing a technique of specific nucleic acids associated with proteins (SNAAP), 13 potential target mRNAs of zebrafish Dnd (ZDnd) protein were identified from 8-cell embryo, and 8 target mRNAs have been confirmed using an RT-PCR analysis. Of the target mRNAs, the present study is focused on the regulation of geminin, which is an inhibitor of DNA replication. Using electrophoretic mobility shift assay (EMSA), we demonstrated that ZDND protein bound the 67-nucleotide region from 864 to 931 in the 3`UTR of geminin mRNA, a sequence containing 60.29% of uridine. Results from a dual-luciferase assay in HEK293 cells showed that ZDND increases the translation of geminin. Taken together, the identification of target mRNA for ZDnd will be helpful to further explore the biological function of Dnd in zebrafish germ-line development as well as in cancer cells.

REVIEW : Intestinal Stricture in Crohn`s Disease
( Chen Wang Chang ),( Jau Min Wong ),( Chien Chih Tung ),( I Lun Shih ),( Horng Yuan Wang ),( Shu Chen Wei ) 대한장연구학회 2015 Intestinal Research Vol.13 No.1
Crohn`s disease (CD) is a disease with chronic inflammation of unknown etiology involving any part of the gastrointestinal tract. The incidence and prevalence of CD are increasing recently in Asia. Half of the CD patients will have intestinal complica-tions, such as strictures or fistulas, within 20 years after diagnosis. Twenty-five percentage of CD patients have had at least one small bowel stricture and 10% have had at least one colonic stricture and lead to significant complications. Most of these pa-tients will require at least one surgery during their lifetime. Early diagnosis and evaluation with adequate managements for the patients can prevent disability and mortality of these patient. Here, we reviewed the current incidence of CD with stricture, the etiology of stricture, and how to diagnose and manage the stricture. (Intest Res 2015;13:19-26)
