This study explores Taiwanese college students' awareness and action on UN's Sustainable Development Goals (SDGs) launched in 2015. These goals define key dimensions wherein youth's recognition, appreciation, and implementations ignite global citizenship, therefore enhancing both employability and mobility. The SDGs have set a strong presence in higher education, but perhaps not enough as most studies have not assessed a holistic view of undergraduates' SDGs perception. In a well-globalized Chinese society where undergraduate degrees are as widespread as in Taiwan, this study aims to uncover whether higher education institutions (HEIs) in Taiwan have served as enabling environments for the growth of global citizens. Building on the government's educational reforms and individual policies, it asks: on which aspects have Taiwan excelled or receded, why, and what can our example offer the global community in sowing global citizens? The Importance--Performance Analysis (IPA) grid was conducted to assess college students' recognition and implementation of each goal. A list of 17 goals and 68 items were identified from literature reviews and each item was rated using a five-point Likert scale. On the scale, the online survey enables the 1238 college students from HEIs, ranging from research to non-research ones, to rate the relative importance of the items, followed by another performance rating. We aspire analysis of the responses to allow reflection on the implementation of professional and general education, as results indicate the factors contributing to students' cognition of the SDGs. Echoing current policy in Taiwan, we intend to offer insights and recommendations to extend students' SDGs vision, ultimately enhancing youth's international understanding and mobility.

The purpose of this study was to examine the relationships among homework time, homework frequency, and learning achievements of Taiwanese students. Applying a 2-level hierarchical linear modeling on the TIMSS 2007 and 2011 data, our findings were as follows: (1) Within the context of TIMSS 2007 and 2011 students, the frequency of mathematics homework positively predicted mathematics learning achievements; (2) Within the context of TIMSS 2007 students, the amount of time spent doing mathematics homework positively predicted mathematics learning achievements. (3) Among TIMSS 2011 students, homework time in mathematics of 1 to 15 minutes, 16 to 30 minutes, 31 to 60 minutes, and 61 to 90 minutes all could positively predict mathematics learning achievements of Taiwanese 8th-grade students, except for homework time more than 90 minutes. It revealed that in relation to mathematics homework time, too much homework might be as bad as not enough.

This study aims to explore relationship between teacher self-efficacy and teacher teaching practice in junior high schools at Taiwan. TALIS (2018) survey database is adopted, and 3106 teachers were analyzed in this research. Through literature review and exploratory factor analysis (EFA), the research model is assumed to include two constructs (classroom management efficacy and instruction efficacy) in teacher self-efficacy, and three constructs (clarity of instruction practice, cognitive activation practice, and classroom management practice) in teacher teaching practice. Through the analysis of Structural Equation Modeling (SEM), the main findings are as follows. (1) For clarity of instruction practice, instruction efficacy has more positive influences than classroom management efficacy. (2) For classroom management practice, classroom management efficacy as more positive influences than instruction efficacy. (3) For cognitive activation practice, instruction efficacy has positive influences but classroom management efficacy has negative influences.

The purpose of this study is to investigate the indirect effects on the properties of ZrO2 films deposited by atomic layer deposition (ALD) when an Mg-Ca alloy is modified through equal-channel angular pressing (ECAP) following extrusion. The study aims to understand how the increase in CaO content in the native oxide layer of the Mg-Ca alloy influences the crystallinity and defect density of the ZrO2 film. Consequently, the corrosion protection performance of the ZrO2 film is enhanced by 1.2 to 1.5 times. A reduction in the anti-scratch property of the ZrO2 film was also observed, with a critical load reduction of 34 μN. This research provides a detailed analysis of the modifications induced by ECAP on the as-extruded Mg-Ca alloy and its subsequent impact on the properties of the ZrO2 film. [ABSTRACT FROM AUTHOR]

In this study, platinum (Pt) and tungsten (W), two materials with dissimilar coefficients of thermal expansion (CTE) and work functions (WF), are used as the top electrode (TE) and the bottom electrode (BE) in metal/ferroelectric/metal (MFM) structures to explore the ferroelectricity of hafnium zirconium oxide (HZO) with a thickness less than 10 nm. The electrical measurements indicate that a higher CTE mismatch between HZO and TE/BE is beneficial for enhancing the ferroelectric properties of nanoscale HZO thin films. The different WFs of TE and BE generate a built-in electric field in the HZO layer, leading to shifts in the hysteresis loops and the capacitance–voltage characteristics. The structural characterizations reveal that the preferred formation of the orthorhombic phase in HZO is dominated by the W BE. The device in which W is used as the TE and BE (the W/HZO/W MFM structure) presents the optimal ferroelectric performance of a high remanent polarization (2 P r = 55.2 μ C cm−2). The presence of tungsten oxide (WO x ) at the W/HZO interfaces, as revealed by high-resolution transmission microscopy, is also responsible for the enhancement of ferroelectric properties. This study demonstrates the significant effects of different CTEs and WFs of TE and BE on the properties of ferroelectric HZO thin films. [ABSTRACT FROM AUTHOR]

In this study, Co, Cr, and Ni were selected as the equal-atomic medium entropy alloy (MEA) systems, and Si was added to form CoCrNiSi0.3 MEA. In order to further improve its wear and corrosion properties, CrN film was sputtered on the surface. In addition, to enhance the adhesion between the soft CoCrNiSi0.3 substrate and the super-hard CrN film, a Cr buffer layer was pre-sputtered on the CoCrNiSi0.3 substrate. The experimental results show that the CrN film exhibits a columnar grain structure, and the film growth rate is about 2.022 μm/h. With the increase of sputtering time, the increase in CrN film thickness, and the refinement of columnar grains, the wear and corrosion resistance improves. Among all CoCrNiSi0.3 MEAs without and with CrN films prepared in this study, the CoCrNiSi0.3 MEA with 3 h-sputtered CrN film has the lowest wear rate of 2.249 × 10−5 mm3·m−1·N−1, and the best corrosion resistance of Icorr 19.37 μA·cm–2 and Rp 705.85 Ω·cm2.
