Jeffrey Yu,Jun Lian,Ruei-Hong Li,Chen-Sin Hung,Dong-Tai Chen,Yu-Kai Chang 대한운동학회 2024 아시아 운동학 학술지 Vol.26 No.1

Objectives In the past centuries, the concept of “physical education” has changed from a more general concepts including physical activities and sports, to specifically inferring “instruction of physical activity”. Instead, “sports” has become the comprehensive concept of sports, exercise, and physical education. Given to the inconsistent terminologies and English translations of “體育 (ti-yu)” (physical education) and “運 動 (yun-dong)” (sports or exercise) in Mandarin, the purpose of this study was to investigate in the current terminology usage, hierarchy, and the English translation of “體育 (ti-yu)” and “運動 (yun-dong)” in Taiwan. Met hods Three government authorities, two sport related universities, eight top sport and exercise journals, and nighty-six college departments in Taiwan were analyzed. Results “運動 (yun-dong)” was the most widely used terminology as “體育 (ti-yu)” occupied the majority usage among government authorities, sport related universities, and title of top sport and exercise journals. Regarding English translation, despite of “department of physical education”, “sports” remained the most common terminology. Moreover, “體育 (ti-yu)” and “sports” are the highest hierarchy among government authorities, and sport related university; “體育 (ti-yu)” and “physical education” are the highest hierarchy among traditional sport and exercise journals; “運動 (yun-dong)” and “sports” are the highest hierarchy among college departments also the mainstream of current translation and hierarchy. Conclusions “體育 (ti-yu)” was the highest hierarchy in the past. However, “運動 (yun-dong)” has been the mainstream of the highest hierarchy in Mandarin according to college departments. In English, “sport(s)” is the main term in Taiwan when translating “體育 (ti-yu)” and 運動 (yun-dong)”, also being the highest hierarchy. On the other hand, “體育 (ti-yu)” and “physical education” are utilized regarding those departments focusing on educating PE teachers. This study expects the terminology, English translations, and hierarchy being align with the mainstream of current translation and hierarchy in the future.

Chen, Hong-Yu,Tan, Xiang,Wu, Jian-Liang Korean Mathematical Society 2012 대한수학회보 Vol.49 No.1

Let G be a planar graph with maximum degree $\Delta$. The linear 2-arboricity $la_2$(G) of G is the least integer k such that G can be partitioned into k edge-disjoint forests, whose component trees are paths of length at most 2. In this paper, we prove that (1) $la_2(G){\leq}{\lceil}\frac{\Delta}{2}\rceil+8$ if G has no adjacent 3-cycles; (2) $la_2(G){\leq}{\lceil}\frac{\Delta}{2}\rceil+10$ if G has no adjacent 4-cycles; (3) $la_2(G){\leq}{\lceil}\frac{\Delta}{2}\rceil+6$ if any 3-cycle is not adjacent to a 4-cycle of G.

This work describes optical and electrical characteristics of InGaP/GaAs/Ge triple-junction (T-J) solar cells with CdS quantum dots (QDs) fabricated by a novel chemical solution. With the anti-reflective feature at long wavelength and down-conversion at UV regime, the CdS quantum dot effectively enhance the overall power conversion efficiency more than that of a traditional GaAs-based device. Experimental results indicate that CdS quantum dot can enhance the short-circuit current by 0.33 mA/cm2, which is observed for the triple-junction solar cells with CdS QDs of about 3.5 nm in diameter. Moreover, the solar cell conversion efficiency is improved from 28.3% to 29.0% under one-sun AM 1.5 global illumination I-V measurement.

Yu-Hsien Lien,Fu-Yao Liu,Jyy-Ning Chen,Yu-Shan Huang,Yu-Hong Wei,Chiyang Yu,Che-Chi Shu 한국생물공학회 2019 Biotechnology and Bioprocess Engineering Vol.24 No.2

Water lettuce (Pistia stratiotes) is one of the most well-known aquatic weeds as it causes problems in watercourses all over the world. This invasive species is fast-growing and thus has the potential for its use in preparing growth medium of microorganisms. Toward it, the pretreatment and enzymatic saccharification are positively the decisive processes. But there are other crucial processes, which are usually ignored by researchers. To the best of my knowledge, this presented work is the first time discovering that the juice obtained from water lettuce is valuable. Except for sterilization, no treatment is needed for the water lettuce’s juice and it can be directly served for cell growth. For Escherichia coli, Saccharomyces cerevisiae, Pichia pastoris, Bacillus subtilis, Lactococcus Lactis, Lactobacillus rhamnosus, and Lactobacillus plantarum, the cell density in the broth of water lettuce’s juice as the only carbon source is 10-60% higher than that in LB, YPD, BHI, M17, MRS. We then examined the production of microbial lipid by YM prepared in the juice of water lettuce. In comparison to commercial medium YM broth, the YM with juice caused 84% increase in the production of microbial lipid. A simple process of collecting juice notably increased productivity.

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]

Hong-Lin Xu,Guang-Hong Chen,Yu-Ting Wu,Ling-Peng Xie,Zhang-Bin Tan,Bin Liu,Hui-Jie Fan,Hong-Mei Chen,Gui-Qiong Huang,Min Liu,Ying-Chun Zhou 고려인삼학회 2022 Journal of Ginseng Research Vol.46 No.1

Background: Panax ginseng Meyer (P. ginseng), a herb distributed in Korea, China and Japan, exerts benefits on diverse inflammatory conditions. However, the underlying mechanism and active ingredients remains largely unclear. Herein, we aimed to explore the active ingredients of P. ginseng against inflammation and elucidate underlying mechanisms. Methods: Inflammation model was constructed by lipopolysaccharide (LPS) in C57BL/6 mice and RAW264.7 macrophages. Molecular docking, molecular dynamics, surface plasmon resonance imaging (SPRi) and immunofluorescence were utilized to predict active component. Results: P. ginseng significantly inhibited LPS-induced lung injury and the expression of proinflammatory factors, including TNF-a, IL-6 and IL-1b. Additionally, P. ginseng blocked fluorescence-labeled LPS (LPS488) binding to the membranes of RAW264.7 macrophages, the phosphorylation of nuclear factor-kB (NF-kB) and mitogen-activated protein kinases (MAPKs). Furthermore, molecular docking demonstrated that ginsenoside Ro (GRo) docked into the LPS binding site of toll like receptor 4 (TLR4)/myeloid differentiation factor 2 (MD2) complex. Molecular dynamic simulations showed that the MD2-GRo binding conformation was stable. SPRi demonstrated an excellent interaction between TLR4/MD2 complex and GRo (KD value of 1.16 × 10<SUP>-9</SUP> M). GRo significantly inhibited LPS488 binding to cell membranes. Further studies showed that GRo markedly suppressed LPS-triggered lung injury, the transcription and secretion levels of TNF-α, IL-6 and IL-1β. Moreover, the phosphorylation of NF-kB and MAPKs as well as the p65 subunit nuclear translocation were inhibited by GRo dose-dependently. Conclusion: Our results suggest that GRo exerts anti-inflammation actions by direct inhibition of TLR4 signaling pathway.

Chen, Jian,Chen, Jie,Ding, Hong-Yan,Pan, Qin-Shi,Hong, Wan-Dong,Xu, Gang,Yu, Fang-You,Wang, Yu-Min Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

Background: The statistical methods to analyze and predict the related dangerous factors of deep fungal infection in lung cancer patients were several, such as logic regression analysis, meta-analysis, multivariate Cox proportional hazards model analysis, retrospective analysis, and so on, but the results are inconsistent. Materials and Methods: A total of 696 patients with lung cancer were enrolled. The factors were compared employing Student's t-test or the Mann-Whitney test or the Chi-square test and variables that were significantly related to the presence of deep fungal infection selected as candidates for input into the final artificial neural network analysis (ANN) model. The receiver operating characteristic (ROC) and area under curve (AUC) were used to evaluate the performance of the artificial neural network (ANN) model and logistic regression (LR) model. Results: The prevalence of deep fungal infection from lung cancer in this entire study population was 32.04%(223/696), deep fungal infections occur in sputum specimens 44.05%(200/454). The ratio of candida albicans was 86.99% (194/223) in the total fungi. It was demonstrated that older (${\geq}65$ years), use of antibiotics, low serum albumin concentrations (${\leq}37.18g/L$), radiotherapy, surgery, low hemoglobin hyperlipidemia (${\leq}93.67g/L$), long time of hospitalization (${\geq}14$days) were apt to deep fungal infection and the ANN model consisted of the seven factors. The AUC of ANN model($0.829{\pm}0.019$)was higher than that of LR model ($0.756{\pm}0.021$). Conclusions: The artificial neural network model with variables consisting of age, use of antibiotics, serum albumin concentrations, received radiotherapy, received surgery, hemoglobin, time of hospitalization should be useful for predicting the deep fungal infection in lung cancer.

List injective coloring of planar graphs with girth at least five

Hong-Yu Chen 대한수학회 2024 대한수학회보 Vol.61 No.1

A vertex coloring of a graph $G$ is called injective if any two vertices with a common neighbor receive distinct colors. A graph $G$ is injectively $k$-choosable if any list $L$ of admissible colors on $V(G)$ of size $k$ allows an injective coloring $\varphi$ such that $\varphi(v)\in L(v)$ whenever $v\in V(G)$. The least $k$ for which $G$ is injectively $k$-choosable is denoted by $\chi_{i}^{l}(G)$. For a planar graph $G$, Bu et al.~proved that $\chi_{i}^{l}(G)\leq\Delta+6$ if girth $g\geq5$ and maximum degree $\Delta(G)\geq8$. In this paper, we improve this result by showing that $\chi_{i}^{l}(G)\leq\Delta+6$ for $g\geq5$ and arbitrary $\Delta(G)$.
