RESUMO
Background: With the ongoing push to improve the quality of talent in all professions, academic pressure on undergraduates is gradually increasing, leading to students feeling increasingly frustrated by academic stressors. As it becomes more widespread, the resulting issue of academic frustration is attracting public attention. Aim: The current study explored the relationship between undergraduate anti-frustration ability (AFA) on their academic frustration (AF), focusing specifically on the roles played by core competence (CC) and coping style (CS) in this relationship. Methods: Our sample comprised 1,500 undergraduate students from universities in China. Data collection made use of the Ability to Anti-Frustration Ability Questionnaire, the Academic Frustration Questionnaire, the Core Competence Questionnaire, and the Simple Coping Style Questionnaire. Results: The results showed that: (1) AFA negatively predicted the AF of undergraduates, with CC mediating this relationship and (2) CS had a moderating effect on the relationship between CC and AF. We concluded that students who employ positive CS may be more successful in alleviating their AF to a larger extent, with the mediation of CC. Interpretation: The results revealed the mechanism of AFA on AF, which will help schools consider and guide students' skills and abilities, both academically and personally.
RESUMO
A gas sensor based on a ZnGa2O4(ZGO) thin film grown by metalorganic chemical vapor deposition operated under the different temperature from 25 °C to 300 °C is investigated in this study. This sensor shows great sensing properties at 300 °C. The sensitivity of this sensor is 22.21 as exposed to 6.25 ppm of NO and its response time is 57 s. Besides that, the sensitivities are 1.18, 1.27, 1.06, and 1.00 when exposed to NO2(500 ppb), SO2 (125 ppm), CO (125 ppm), and CO2 (1500 ppm), respectively. These results imply that the ZGO gas sensor not only has high sensitivity, but also has great selectivity for NO gas. Moreover, the obtained results suggest that ZGO sensors are suitable for the internet of things(IOT) applications.
RESUMO
BACKGROUND: Studies comparing the growth of children between Tibetan and Han ethnic groups have not been reported. OBJECTIVE: To increase the understanding regarding the growth status of children and the growth difference between the Tibetan and Han ethnic groups. METHODS: Body weight, body height, and BMI of 894 Tibetan monks aged from 8-17 years old, residing in South India were collected, while growth information for boys in Taiwan was obtained from the Taiwan growth chart developed in 1997. RESULTS: In the 50th percentile, the median height difference between those boys 8 and 17 years of age was 46.8 cm, with a 5-6 cm increase each year. The median weight difference between 8- and 17-year-old groups was 33 kg, with a 0-6.5 kg increase each year. Each year, the BMIs of monks in the 5th, 50th, and 95th percentiles had 3.0-5.4%, 1.6-10%, and 3.1-8.8% increased rates, respectively. The differences of height and weight between the two groups increased between the ages of 9 and 14 years of age, but Taiwan boys and Tibetan monks had nearly the same height and weight at 17 years old. Based on the BMI-for-age curve, there were more Taiwanese boys overweight or obese than Tibetan monks. CONCLUSIONS: Even after using the data of ten years ago in Taiwan, Taiwanese boys had superior nutrition and growth status compared with Tibetan monks between the ages of eight and seventeen years, inclusive. In addition, racial differences might also play a significant factor in growth.
