A study on the social and cultural context of toys for primary school children

In response to the post-epidemic relationship and other factors, the number of students who transfer from abroad is increasing daily. The timing and reasons such children return to their hometown to study nowadays are extremely diverse, often appearing in the floating population, emergencies, and individual cases. At present, more and more "international transfer students" appear in the education system of their hometown and home country, and they are facing great difficulties in academic and interpersonal relationships. Because of their lack of language skills, such children cannot successfully integrate into the education system after returning to their hometowns. In order to protect students' learning rights and avoid becoming "guests in the classroom," this study starts from the social and cultural context of toys among elementary school children; Analyzed and explored their cultural background through evaluation constructs, user journey maps, questionnaires, and applied grounded theory in qualitative research, as well as their emotional ups and downs during the game. Explore objects' meaning and relationships represented in the social culture of children to explore the emotional motivation of school children and the preferences of product modeling. It aims to understand the relationship between personal emotional fluctuations, environmental and behavior of use, hoping to create more possibilities for future curriculum development and toy design. This study adopts between-subjects design to investigate the acceptance level and psychological experience process of 120 elementary school children in the process of experiencing the interactive integration of toys into learning. Among them, 60 students are Eastern Asians and 60 are Western foreign students. Interview and record analysis. And from the popular toys on the e-commerce platform on the market, 20 items were screened out one by one for the classification of interactive toys and experience , integrated into the research and investigation of these 120 elementary school children, observed and recorded through questionnaires and interviews

Hafnium oxide-based ferroelectric thin-film transistor with a-InGaZnO channel fabricated at temperatures \u3c= 350°C

HfO2-based ferroelectric materials integrated with oxide-based thin-film transistors have been considered as potential candidates for back-end-of-line compatible ferroelectric field-effect transistors, which can be vertically stacked on silicon CMOS circuits to realize high-density neural network applications. However, the formation of ferroelectric orthorhombic phase in HfO2-based materials usually requires an annealing temperature of 400°C or higher. In this work, ferroelectric thin-film transistors (Fe-TFTs) were developed by monolithically integrating HfZrO2 (HZO) ferroelectric capacitors with amorphous indium-gallium-zinc oxide (a-IGZO) TFTs at a maximum processing temperature of 350°C on a glass substrate. A butterfly-shaped C-V curve was clearly observed in the low-temperature annealed metal-HZO-metal capacitor, indicating the formation of ferroelectricity in the HZO layer, as shown in Fig. 1. The positive and negative coercive voltages were 3 V and -2.4 V, respectively. The dielectric constant was 20.65. The field-effect mobility, threshold voltage, subthreshold swing and on/off current ratio of the a-IGZO TFT extracted from the transfer characteristics shown in Fig. 2 were 6.15 cm2V-1s-1, 1.5 V, 0.1 V/dec and 4.3´107, respectively. Fig. 3 shows the transfer hysteresis curves of the low-temperature Fe-TFTs in a metal-ferroelectric-metal-insulator-semiconductor configuration. The Fe-TFTs exhibited large hysteresis memory windows of 2.8 V and 3.8 V when the area ratios between ferroelectric capacitors and gate insulators (AFE / ADE) were 1/8 and 1/12, respectively. The result shows a great potential for back-end-of-line compatible memory applications. Please click Download on the upper right corner to see the full abstract

Comparison of the Prevalence of Metabolic Syndrome Between the Criteria for Taiwanese and Japanese and the Projected Probability of Stroke in Elderly Hypertensive Taiwanese

SummaryBackgroundThe cutoff of abdominal circumference for metabolic syndrome (MS) defined by the Bureau of Health Promotion (BHP) of Taiwan for Taiwanese (men, 90cm; women, 80cm) and by the International Diabetes Federation (IDF) for Japanese (men, 85cm; women, 90cm) differs. This study aimed to examine the impact of this difference on the prevalence of MS and the impact of an MS diagnosis on the projected risk of stroke in hypertensive Taiwanese.MethodsMS was examined in a sample of 3,472 hypertensive patients (aged 55–80 years; 1,709 women) across Taiwan. The 10-year probability of stroke estimated from the Framingham equation was compared between MS and non-MS patients.ResultsThe prevalence of MS using the BHP criteria was 59.2% using the BHP criteria (95% confidence interval, CI, 57.6–60.8%; men, 52.5%; women, 66.1%) and 48.9% by the IDF criteria (95% CI, 47.2–50.5%; men, 61.3%; women, 36.1%). Both criteria showed that, compared with non-MS, MS has higher predicted 10-year probability of stroke (BHP, 0.153 ± 0.115 vs. 0.133 ± 0.105; IDF, 0.159 ± 0.109 vs. 0.132 ± 0.112; both p < 0.001) because of the difference in women (BHP, 0.143 ± 0.124 vs. 0.102 ± 0.091; IDF, 0.147 ± 0.121 vs. 0.118 ± 0.110; both p < 0.001) rather than men (BHP, p = 0.21; IDF, p = 0.29).ConclusionBoth criteria demonstrate that MS is highly prevalent in elderly hypertensive patients in Taiwan. Additionally in women, but not men, the predicted probability of stroke is higher in MS than in non-MS patients. The diagnosis of MS is potentially useful for identifying elderly hypertensive females with an elevated risk of stroke in Taiwan

Serum ferritin levels and polycystic ovary syndrome in obese and nonobese women

AbstractObjectiveThe aim of this study is to evaluate serum ferritin levels and polycystic ovary syndrome (PCOS)-related complications in obese and nonobese women.Materials and methodsThis retrospective study included 539 (286 with PCOS and 253 without PCOS).ResultsSerum ferritin correlated with menstrual cycle length, sex hormone-binding globulin, total testosterone, androstenedione, triglyceride, and total cholesterol in both obese and nonobese women. Obese women with high ferritin levels exhibited higher insulin resistance, impaired glucose tolerance, and liver enzymes (glutamic oxaloacetic transaminase, glutamic pyruvic transaminase) than obese women with low ferritin levels. However, among nonobese women, insulin resistance and risk of diabetes were not significantly different between the high and low ferritin groups. Independent of obesity, hypertriglyceridemia was the major metabolic disturbance observed in women with elevated serum ferritin levels.ConclusionElevated serum ferritin levels are associated with increased insulin resistance and risk of diabetes in obese women but not in nonobese women. However, higher serum ferritin levels were correlated with a greater risk of hyperglyceridemia in both obese and nonobese women. Therefore, hypertriglyceridemia in women with PCOS might be associated with iron metabolism

To Fee or Not to Fee? Satisfaction, Service Quality, and Support of an Entrance Fee of a State Park System

In the past decade, state government appropriation reductions have forced park agencies to seek other sources of revenue to support park operations. To overcome shrinking budgets, many public park agencies embrace private sector business models and investigate customer satisfaction, service quality, and user fee structures. The purpose of this study was to obtain public input regarding service quality, general satisfaction, and experience use history of state park visitation. A total of 382 Oklahoma state park users completed an online survey and were sorted into Pro-Fee (n = 200, 52%) and No-Fee (n = 182, 48%) groups for one-way multivariate analysis of variance (MANOVA) tests. The researchers found a significant difference between the two groups on service quality, but not on overall satisfaction or behavioral intention (e.g., revisit, recommending the park). When comparing Pro-Fee and No-Fee groups, researchers found no statistically significant variance in visitors’ demographics, such as gender, education level, and income, whereas the number of years that had passed since the visitors’ first visit showed a significant difference between the groups. The findings of this study provide valuable insight for discussions related to entrance fees and service fees in state park systems

AGE-BSA down-regulates endothelial connexin43 gap junctions

<p>Abstract</p> <p>Background</p> <p>Advanced glycation end products generated in the circulation of diabetic patients were reported to affect the function of vascular wall. We examined the effects of advanced glycation end products-bovine serum albumin (AGE-BSA) on endothelial connexin43 (Cx43) expression and gap-junction communication.</p> <p>Results</p> <p>In human aortic endothelial cells (HAEC) treated with a series concentrations of AGE-BSA (0-500 μg/ml) for 24 and 48 hours, Cx43 transcript and Cx43 protein were reduced in a dose dependent manner. In addition, gap-junction communication was reduced. To clarify the mechanisms underlying the down-regulation, MAPKs pathways in HAEC were examined. Both a MEK1 inhibitor (PD98059) and a p38 MAPK inhibitor (SB203580) significantly reversed the reductions of Cx43 mRNA and protein induced by AGE-BSA. Consistently, phosphorylation of ERK and p38 MAPK was enhanced in response to exposure to AGE-BSA. However, all reversions of down-regulated Cx43 by inhibitors did not restore the functional gap-junction communication.</p> <p>Conclusions</p> <p>AGE-BSA down-regulated Cx43 expression in HAEC, mainly through reduced Cx43 transcription, and the process involved activation of ERK and p38 MAPK.</p

Resident Perceptions of Black Bear Management in South Central Kentucky

The growth and sprawl of the American black bear (Ursus americanus ) population have been observed and monitored in the past two decades, especially in south-central Kentucky. To better manage human-black bear interaction and develop informed policy and best practices, the current study sought to 1) understand south-central Kentucky residents’ current knowledge of and previous experience with black bears, 2) investigate residents’ attitudes toward black bears and regulated hunting in wildlife management; and 3) identify residents’ level of acceptance of various black bear related management actions in south-central Kentucky. From February to April 2017, residents of London and Stearns districts (southeastern regions) of the Daniel Boone National Forest, a black bear habitat, were invited to participate in this study. The results from 139 completed surveys showed that residents lacked sufficient knowledge about black bear populations in the region and received minimal information regarding black bear management efforts. In comparison to education efforts and relocation, regulated black bear hunting could be a cost-effective option to promote responsible use of wildlife resources and black bear population control. This study provided lessons and recommendations for black bear management in south-central Kentucky and may be of utilization for any other wildlife conservation areas
