HPT research studies and practices have been largely conducted in the corporate setting, leaving education as a neglected context despite its strong emphasis on performance in teaching, learning, and school management. In this study, we examine the application of the HPT standards and their effects on Korean teachers’ performance goal achievement for students. With HPT standards, we also investigate the interaction effect of teacher tenure on the relationship among HPT standards and goal achievement. The Hayes Process Model is adopted to examine the second-stage moderated mediation model. The findings support that the principle standards positively mediate the effect of the process standards on the teachers’ goal achievement, and teacher tenure moderates the HPT standards’ effects on goal achievement. The practical and theoretical implications of the results are discussed, as well as limitations and future research suggestions

This study examined the effects of freshwater discharge by artificial dikes from the Kanwol and Bunam lakes on the dynamics in the Chunsu Bay, Yellow Sea, Korea, during the summer season based on three-dimensional numerical modeling experiments. Model performances were evaluated in terms of skill scores for tidal elevation, velocity, temperature, and salinity and these scores mostly exceeded 90 %. The variability in residual currents before and after the freshwater discharge was examined. The large amount of lake water discharge through artificial dikes may result in a dramatically changed density field in the Chunsu Bay, leading to an estuarine circulation system. The density-driven current formed as a result of the freshwater inflow through the artificial dikes (Kanwol/Bunam) caused a partial change in the tidal circulation and a change in the scale and location of paired residual eddies. The stratification formed by strengthened static stability following the freshwater discharge led to a dramatic increase in the Richardson number and lasted for a few weeks. The strong stratification suppressed the vertical flux and inhibited surface aerated water mixing with bottom water. This phenomenon would have direct and indirect impacts on the marine environment such as hypoxia/anoxia formation at the bottom.

The design and fabrication of catalysts with low-cost and high electrocatalytic activity for the oxygen evolution reaction (OER) have remained challenging because of the sluggish kinetics of this reaction. The key to the pursuit of efficient electrocatalysts is to design them with high surface area and more active sites. In this work, we have successfully synthesized a highly stable and active NiCo2S4 nanowire array on a Ni-foam substrate (NiCo2S4 NW/NF) via a two-step hydrothermal synthesis approach. This NiCo2S4 NW/NF exhibits overpotential as low as 275 mV, delivering a current density of 20 mA cm-2 (versus reversible hydrogen electrode) with a low Tafel slope of 89 mV dec-1 and superior long-term stability for 20 h in 1M KOH electrolyte. The outstanding performance is ascribed to the inherent activity of the binder-free deposited, vertically aligned nanowire structure, which provides a large number of electrochemically active surface sites, accelerating electron transfer, and simultaneously enhancing the diffusion of electrolyte.

The purpose of this study is to evaluate the application of a web-based cost management competency enhancement program (Web-CMCEP) on nursing students. Medical services are limited and essential for maintenance of human basic life. In order to improve the quality of human life, cost management competency that enable efficient allocation of medical resources are essential. This study adopts a randomized controlled pre/post repeated measure design. The sample comprised 39 nursing students in the web-group and 35 in the textbook-group. Experimental group and control group learned respectively with Web- CMCEP and textbook for 4 weeks. The research variables were measured at 4 times: pre, post, after 4 weeks of intervention, and after 8 weeks of intervention. Data were analyzed using χ2 -test, t-test, paired t-test, repeated measures ANOVA, Friedman test, and Wilcoxon signed rank test. Significant differences were found in cost management knowledge. The web-group showed higher cost management knowledge than the text-group. At different measuring points, the Web-CMCEP led to significant increases in the following: cost management knowledge, cost management attitude, cost management behavior, cost management self-efficacy, and entrepreneurship. Based on the findings, we suggested utilizing the Web-CMCEP as a prototype in developing education programs to improve nursing students’ cost management competency and to support nursing start-ups.

This study was conducted for the purpose of discovering deficiencies within education- related assistance projects of private organizations that provide educational programs for developing countries. Based on the dynamic graph and educational performance of the educational ODA of 11 private institution, the adequacy of the educational projects was analyzed in terms of the following four factors: ‘Improvement of educational environment and expansion of educational opportunities’, ‘Educational system competency’, ‘Competency of education recipients’ and ‘Community formation and social reform’. The analysis found that two institutions were conducting programs corresponding to 3 out of the 4 factors while the remaining nine were conducting programs to achieve two factors. That is, the 11 institutions were appropriately carrying out educational ODA projects. To further invigorate ODA, however, it was found that it will be necessary to reinforce ‘social reform’ through ‘educational system competency’ or ‘community formation.’ This study is meaningful in that as it used a methodology that had never been used before, and analyzed the educational ODA of private institutions.
