Opis:
Aim. The aim of the article is to understand how Chinese parents draw on their learning beliefs and experiences within the Chinese educational context to make decisions about their children’s overseas education, as well as analysing how their learning beliefs are similar or different from East Asian or Western learning beliefs. Methods. The study is based on more than 100 in-depth separate interviews with 22 Chinese families conducted over serval years between 2016 and 2019. Based on interpretative phenomenological analysis and discourse analysis, the results are coded according to the theory of values proposed by Clyde Kluckhohn (1951). These learning values are further coded according to whether they are reflective of the American learning model (EALM), Confucian learning model (CLM), and Confucian learning philosophies. Results. The analysis shows that Chinese parents have displayed similar learning beliefs in socialising their children in the family domain, in their disapproval of the Chinese education system, and in their pursuit of a Western overseas education. The Chinese families’ pursuit of a Western education for their children are driven by their cultural leaning beliefs, which are rooted in Confucian heritage culture, and which also echo European American heritage cultures. Conclusion. Many researchers tend to emphasise cultural differences in learning, particularly between Confucian heritage and European American heritage cultures. This paper shows the possibilities of cultural learning values shaping educational choices, expands upon the understanding of Confucian heritage culture, and suggests the similarities between the learning cultures of East Asia and the West.

Opis:
The normal mode solution for the form function and target strength (TS) of a solid-filled spherical shell is derived. The calculation results of the spherical shell’s acoustic TS are in good agreement with the results of the finite element method (FEM). Based on these normal mode solutions, the influences of parameters such as the material, radius, and thickness of the inner and outer shells on the TS of a solid-filled spherical shell are analyzed. An underwater spherical shell scatterer is designed, which uses room temperature vulcanized (RTV) silicone rubber as a solid filling material and does not contain a suspension structure inside. The scatterer has a good TS enhancement effect.

Opis:
Owing to expensive cost and restricted structure, limited sensors are allowed to install in modern systems to monitor the working state, which can improve their availability. Therefore, an effective sensor placement method is presented based on a VIKOR algorithm considering common cause failure (CCF) under epistemic uncertainty in this paper. Specifically, a dynamic fault tree (DFT) is developed to build a fault model to simulate dynamic fault behaviors and some reliability indices are calculated using a dynamic evidence network (DEN). Furthermore, a VIKOR method is proposed to choose the possible sensor locations based on these indices. Besides, a sensor model is introduced by using a priority AND gate (PAND) to describe the failure sequence between a sensor and a component. All placement schemes can be enumerated when the number of sensors is given, and the largest system reliability is the best alternative among the placement schemes. Finally, a case study shows that CCF has some influence on sensor placement and cannot be neglected in the reliabilitybased sensor placement.

Opis:
The effects of different surface modifiers on the CO2 adsorption capacity of coal-based activated carbons were studied, and the diffusion behavior, adsorption kinetics and thermodynamic parameters of CO2 in activated car-bons were analyzed. The results show that compared with ethylene glycol, 1,2-propylenediamine and zinc chloride, potassium hydroxide and sodium hydroxide can greatly improve CO2 adsorption capacity. The adsorption rate is faster, and the adsorption capacity is larger, with the maximum CO2 adsorption capacity being 33.54 mL/g. Fick’s law can well describe the diffusion behavior of CO2 in activated carbon. The addition of a surface modifier can increase the diffusion coefficient. The diffusion of CO2 in activated carbon falls into the category of crystal diffusion. The adsorption kinetics of CO2 before and after surface modification follow the Bangham equation. During the adsorption process, δ H < 0, δ G < 0, δ S < 0. Surface modification can reduce adsorption heat and promote adsorption, and the adsorption process is dominated by physisorption.

Opis:
Objectives The authors used the National Aeronautics and Space Administration Task Load Index (NASA-TLX) and general health questionnaire to analyze the factors influencing the mental health status and the workload of support nurses during the COVID-19 epidemic. Material and Methods The authors conducted a cross-sectional survey of 349 support nurses in April–October 2022. Using QuestionStar, a powerful online survey tool, the authors administered surveys to the participants, collected data on the mental health status and workload of support nurses, and analyzed the influencing factors based on the collected data. Results A total of 316 questionnaires were successfully collected, with an effective rate of 98.75%. The proportion of support nurses with mental health problems was 25% and the value of the NASA-TLX questionnaire was: M±SD 68.91±7.28 pts. Multi-factor analysis revealed that the number of children, family support, and nursing support location were the influencing factors of mental health status, while the multivariate analysis revealed that the presence of symptoms, nursing support location, support work type, and total 12-item General Health Questionnaire (GHQ-12) score were the influencing factors of the workload of support nurses. Conclusions Compared to their counterparts in the plains, nurses working in isolated plateau regions who were caring for children and lacked family support, were more likely to have mental health issues. There was a positive correlation between the changes in GHQ-12 and NASA-TLX scores of the study participants. Compared to their counterparts in the plains and the tropical regions, nurses working in plateau regions had a heavier workload. As part of the follow-up measures to prevent and treat patients impacted by the COVID-19 epidemic, it is important to improve the mental health evaluation, consultation, and treatment of the support nurses to guarantee the high quality of the first-line support work.

Opis:
To improve the clinical effect of scutellarin by extending the action time in vivo, scutellarin loaded polymeric micelles were developed by D-alpha tocopherol polyethylene glycol 1000 succinate (Scu/TPGS). Scu/TPGS were prepared using film solvent diffusion methods and characterized on the basis of their particle size, zeta potential, and drug encapsulation efficiency. Dynamic dialysis was used to study the release behavior of the polymeric micelles in vitro. Its pharmacokinetic characteristics and antithrombotic efficacy were studied by intravenous injection in rats. The results showed that Scu/TPGS were spherical, 20.09±2.62 nm in size and a slow release in vitro. The pharmacokinetic parameter T1/2 of Scu/TPGS was 762.12±46.56 min compared with commercial injection of 59.30±10.67 min (p<0.05). At the 1 mg/kg dose, the thrombolysis effect of micellar group was stronger than that of the commercial group (p<0.05). In conclusion, TPGS polymer micelles provided a valid strategy in chemotherapy for cerebrovascular diseases with poor water solubility and poor lipid solubility drugs such as scutellarin.

Opis:
Insulin resistance (IR) plays a critical role in metabolic syndrome (MS). Previous studies have demonstrated that activated ROCK is increased in MS patients. However, the effect of Rho-kinase (ROCK) on IR has not been definitely determined. Thus, the aims of the present study were to determine whether ROCK activation induces IR or affects myocardial structure and function, as well as the possible mechanisms underlying this process. Wistar rats fed high fat, high glucose and high salt diet sewed as model of MS and we used transmission electron microscopy, echocardiogram technology, and terminal deoxynucleotidyl transferase-mediated DNA nick-end labeling staining to identify any myocardial damage. The protein levels of MYPT-1 (characteristic of ROCK activation), IRS-1 and AKT were analyzed by immunohistochemistry and Western blotting. In hearts from MS rats, we found increased protein levels of phospho-MYPT-1 and phospho-IRS-1 (Ser307) and decreased phospho-AKT compared to levels in normal rats. In conclusion, the results suggest that ROCK-mediated IR is involved in the development of myocardial impairments in MS rats and that this effect is mediated probably via the IRS-1/PI3-kinase/AKT pathway.
