The process of searching for information to serve the construction of operational plan documents on a digital map is still being done manually and needs to be automated in order to improve efficiency. Speech recognition and natural language processing technologies, commonly used in chatbots, virtual assistants, voice commands, and voice search, could be promising tools to overcome this problem. This paper proposes a framework for deploying a voice search engine that uses Whisper, a deep learning-based automatic speech recognition model, and combines TF-IDF, N-gram, and Truncated SVD as feature extraction approaches to search for text ground truth in a dictionary of military symbols using Cosine similarity. Despite the small size of a custom dataset, the experiments show promising results, achieving an accuracy of 82.00%. Our achievement surpasses that of several traditional statistical methods and classification models.

The beliefs in Vietnamese Mother Goddesses Worship, commonly called Mother Goddesses, worship Mother Goddesses herself, Mother Goddess of Three Palaces and Four Palaces appear to be quite popular and have deep historical and social origins among the people of Lam Dong province, Vietnam.. Although they are all worship of feminine gods, the worship of goddesses, “Thanh Mau”, “Thanh Co”, Mother of the Three Palaces, and the Four Palaces are not completely identical. This article explores the process of formation, development and typical features of Mother Goddess worship in the cultural life of people in Lam Dong province, Vietnam. Based on the analysis of the actual situation of worshiping Mother Goddesses of the people of Lam Dong, the authors propose a number of policy implications that contribute to preserving the beauty of Mother Goddess worship and promoting the Vietnamese culture of progressive, imbued with beautiful national identity.

RESEARCH QUESTION: Is there an association between FSHR sequence variants and reproductive outcomes following IVF in predicted normoresponders? DESIGN: Multicentre prospective cohort study conducted from November 2016 to June 2019 in Vietnam, Belgium and Spain including patients aged G, c.2039A>G, c.-29G>A) and one FSHB sequence variants (c.-211G>T). Clinical pregnancy rate (CPR), live birth rate (LBR) and miscarriage rate in the first embryo transfer and cumulative live birth rate (CLBR) were compared between the different genotypes. RESULTS: A total of 351 patients underwent at least one embryo transfer. Genetic model analysis that adjusted for patient age, body mass index, ethnicity, type of embryo transfer, embryo stage and number of top-quality embryos transferred revealed a higher CPR for homozygous patients for the variant allele G of c.919A>G when compared to patients with genotype AA (60.3% versus 46.3%, adjusted odds ratio [ORadj] 1.96, 95% confidence interval [CI] 1.09-3.53). Also, c.919A>G genotypes AG and GG presented a higher CPR and LBR when compared with genotype AA (59.1% versus 46.3%, ORadj 1.80, 95% CI 1.08-3.00, and 51.3% versus 39.0%, ORadj 1.69, 95% CI 1.01-2.80, respectively). Cox regression models revealed a statistically significantly lower CLBR for c.2039A>G genotype GG in the codominant model (hazard ratio [HR] 0.66, 95% CI 0.43-0.99). CONCLUSION: These results demonstrate a previously unreported association between variant c.919A>G genotype GG and higher CPR and LBR in infertile patients and reinforce a potential role for genetic background in predicting the reproductive prognosis following IVF.

A multivariate analysis of variance test, Pearson Correlation, and analyzing mediating variable interaction is used to analyze data.Results: The findings suggested a significant interaction between personality traits, specifically extraversion and neuroticism, and physical aggression, verbal aggression, and anger. Students with higher levels of personality had higher levels of verbal aggression, and students with higher levels of physical aggression and anger had stronger personality traits than others and lower levels of physical aggression and anger. Personality traits, specifically extraversion, and neuroticism, differed significantly by gender and school years in adolescence. Mediation analysis revealed a positive and statistically significant indirect correlation between personality traits and physically aggressive behavior, with anger as a mediator. Similarly, a positive and statistically significant indirect correlation between personality traits and verbally aggressive behavior through anger was found. The relationship between personality traits and physical aggression was also significant via verbal aggression and anger.Conclusion: This study improved our understanding of personality traits and verbal or physical aggression. Most crucially, physical and verbal aggression mediate personality traits and aggressive conduct. In secondary school, gender and school year affected extraversion and neuroticism. This discovery illuminates personality-based aggressiveness intervention.Keywords: adolescent, personality, aggressive behavior, physical aggression, verbal aggression

The anxiety about COVID-19 was evaluated by the fear of COVID-19 (FOC) scale. A self-developed questionnaire was used to assess work conditions and HCW’s major concerns and preparedness. Ordinal logistic regression was used to identify factors associated with the severity of PTSD. A structural modeling equation (SEM) model was fitted to examine the correlation between PTSD and other psychological disturbances.Results: A total of 542 HCWs participated in this study. The prevalence of PTSD was 21.2%, most cases were mild. In the ordinal logistic regression analysis, a history of mental illness, poor preparedness, working in a condition with poor resources, a greater number of concerns, and greater fear of COVID-19 were independently associated with higher severity of PTSD. The prevalence of depression, anxiety, and stress was 46.8%, 38.3%, and 60.2, respectively. In the SEM model, PTSD and psychological disturbances had a strong correlation (standardized covariance 0.86).Conclusion: The prevalence of PTSD and other psychological disturbances was alarmingly high among HCWs who worked at COVID-19 field hospitals. The reported associated factors can be useful for policymakers and health authorities in the preparation for future pandemics.Keywords: PTSD, COVID-19, healthcare workers, DASS, fear of COVID, psychological disturbances

Background: Echocardiographic deformation-based ratios and novel multi-parametric scores have been suggested to discriminate transthyretin cardiac amyloidosis (ATTR-CM) from other causes of increased left ventricular wall thickness among patients referred for ATTR-CM evaluation. Their relative predictive accuracy has not been well studied. We sought to (1) identify echocardiographic parameters predictive of ATTR-CM and (2) compare the diagnostic accuracy of these parameters in patients with suspected ATTR-CM referred for technetium-99m-pyrophosphate scintigraphy. Methods: Echocardiograms from 598 patients referred to 3 major amyloidosis centers for technetium-99m-pyrophosphate to detect ATTR-CM were analyzed, including longitudinal strain (LS) analysis. Deformation ratios (septal apex to base ratio, relative apical sparing, ejection fraction to global LS), a multi-center European increased wall thickness score, and Mayo Clinic derived ATTR score (transthyretin cardiac amyloidosis score) were calculated. A logistic regression model was used to identify the parameters that best associated with a diagnosis of ATTR-CM. Comparison of the diagnostic capacity of the parameters was performed by receiver operating characteristic curves and the area under the curve (AUC). Results: Over half of the subjects (54.2%) were diagnosed with ATTR-CM (78% were men, median age of 76 years). Age, inferolateral wall thickness, and basal LS were the strongest predictors of ATTR-CM, AUC of 0.87 (95% CI: 0.83, 0.90), superior to the increased wall thickness score AUC of 0.78 (95% CI: 0.73, 0.83; P =0.004). An inferolateral wall thickness of ≥14 mm (AUC: 0.73) was as accurate as the published cut-offs for transthyretin cardiac amyloidosis score and septal apex to base (AUC: 0.72 and 0.69, P =0.8 and P =0.1, respectively), and was superior to ejection fraction to global LS and relative apical sparing (AUC: 0.64 and 0.53, P P =0.2); outperforming the other indices ( P Conclusion: Inferolateral wall thickness and average basal LS performed as well as or better than more complex echo ratios and multiparametric scores to predict ATTR-CM.

Alterations in the epidermal growth factor receptor were confirmed to take a significant role in targeted therapy for patients with lung cancer. Studied 299 non-small cell lung cancer patients to determine the distribution of EGFR mutation and its relationship with clinicopathological characteristics of patients. EGFR mutations were analysed by allele-specific PCR on the Cobas z480 system, and the association between EGFR mutations and patient characteristics was analysed by Pearson Chi-square test and Fisher extract test. The results showed that the frequency of EGFR mutation was 38.8%, in which, Ex19Del and L858R substitution were predominant among overall mutation, 45.4% and 29.1%, respectively. There was no difference between EGFR mutations with age, specimen type, tumour size and histopathological subtype. However, there was a strong correlation between EGFR mutation and gender and tumour status (p

Oocyte in vitro maturation (IVM) has been proposed as an alternative to conventional ovarian stimulation (COS) in subfertile women with polycystic ovary syndrome. To evaluate the effectiveness and safety of IVM compared with COS in women with predicted hyperresponse to gonadotropins, we searched the published literature for relevant studies comparing any IVM protocol with any COS protocol followed by in vitro fertilization or intracytoplasmic sperm injection. A systematic review was undertaken on 3 eligible prospective studies. Live birth rate was not significantly lower after IVM vs. COS (odds ratio [95% confidence interval] of 0.56 [0.32-1.01] overall, 0.83 [0.63-1.10] for human chorionic gonadotropin (hCG)-triggered IVM [hCG-IVM] and 0.45 [0.18-1.13] for non-hCG-triggered IVM [non-hCG-IVM]), irrespective of the stage of transferred embryos. Data from nonrandomized studies generally showed either significantly low or statistically comparable rates of live birth with IVM vs. COS. Most studies have not identified any significant difference between IVM and COS with respect to the rates of obstetric or perinatal complications, apart from a potentially higher rate of hypertensive disorders during pregnancy. The development of offspring from IVM and COS with in vitro fertilization or intracytoplasmic sperm injection appears to be similar. Additional research is needed to identify which patient populations will benefit most from IVM, to define the appropriate clinical protocol, and to develop the optimal culture system.

Objective A brain health equity neuropsychology research framework (NRF) is crucial to the anti-racist movement in cognitive assessments. Universalist interpretation of neuropsychological tools contributes to systemic disparities, and there is a need for a clear conceptual framework for disentangling the direct and indirect impact of social determinants of health (SDH) on brain-behavior relationships and neuropsychological performance. The aim of this paper is to present a NRF anchored in the principles of brain health and health equity that is inclusive, and can be implemented across racially and ethnically diverse communities. Methods The Re-engaging Individuals and societies for Structural Evolution (RISE) NRF aims to address this via a two-pronged approach: 1. Focusing on community engagement and recruitment and retention of individuals and societies typically not equitably represented in brain health studies, and 2. Integrating the conceptual structure of individual, community, and SDH, while considering the broader historical and current structures that differentially shape these. Results The proposed RISE NRF is dynamic and multidirectional. It identifies barriers and proposes strategies to engage communities and diversify recruitment. It identifies evidence-based guidance on non-cognitive determinants of health to include, consider or explore in brain health research. Conclusion The RISE NRF can guide the development of culturally and linguistically responsive methodologies and assist with clearly conceptualized and contextualized interpretation of neuropsychological tools to foment a transformative science that benefits the brain health of marginalized communities.

Objective The Latina(o)/Hispanic (L/H) population represents the largest and fastest-growing ethnic group in the United States. Migration patterns have evolved and greater diversity (i.e., country of origin) is evident, highlighting the ever-changing heterogeneity of this community and the need for the field of neuropsychology to ensure equitable care for linguistically and culturally diverse communities. This paper aims to provide a flexible protocol of neuropsychological instruments appropriate for primarily Spanish-speaking adults residing in the United States. Method Spanish measures were selected based on availability, translations/cultural modifications, accompanying normative data sets, and clinician experience/acumen. Bilingual/bicultural providers of neuropsychological services to Spanish speakers across the training spectrum working at U.S.-based medical centers implemented a multimodal approach (i.e., literature search, clinical practice parameters, and focus groups) in the development of a multi-domain primary protocol that includes core and supplemental measures that are appropriate for individuals with varying linguistic proficiency and sociocultural demographic characteristics. Results A multi-domain, evidence-based, flexible neuropsychological protocol is presented. Recommendations for test selection based on sociocultural demographic factors and examples of clinical assessment practices are provided via a case illustration. Most instruments included may be applied across cultural and regional backgrounds. Conclusion Provision of neuropsychological services to primarily Spanish-speaking adults presents unique challenges. Existing Spanish measures and accompanying data rarely capture the heterogeneity of L/H individuals. Although Spanish has the largest number of neurocognitive instruments, relative to other languages, robust and representative norms continue to be scarce. Future studies should prioritize collecting normative data from educationally and geographically diverse samples.

Diabetic polyneuropathy (DPN) renders progressive sensory neurodegeneration linked to hyperglycemia and its associated metabolopathy. We hypothesized that there may be additive impacts of direct insulin signaling, independent of glycemia and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) knockdown on neuropathy. Our targets for combined interventions were neurons and Schwann cells (SCs) in vitro and chronic type 1 DPN in mice. Insulin receptor expression was not altered by high-glucose conditions in neurons or SCs, and insulin promoted survival of neurons and proliferation of SCs in vitro. There were additive impacts between insulin signaling and PTEN knockdown in sensory neuron outgrowth and in axon myelination by SCs. In a chronic mouse model of experimental DPN, unilateral intra–hind paw injections of a PTEN siRNA and local insulin had additive impacts on correcting key features of chronic experimental DPN independent of glycemia, including motor axon conduction and thermal and mechanical sensory loss. Moreover, combined interventions improved sural and tibial nerve myelin thickness, hind paw epidermal innervation, and pAkt expression in dorsal root ganglion sensory neurons. We conclude that local PTEN inhibition or knockdown and insulin provide additive trophic support for sensory neurons and SCs while reversing key abnormalities of experimental DPN but without requiring metabolic correction. Article Highlights Impaired growth and plasticity of neurons may contribute to chronic diabetic polyneuropathy. Both direct insulin signaling of neurons and neuron knockdown of the protein phosphatase and tensin homolog deleted on chromosome 10 (PTEN), a roadblock to neuronal regenerative growth, offer direct support of neurons. Direct insulin and PTEN knockdown using siRNA had additive impacts on neuron survival, Schwann cell proliferation, neuron outgrowth, and myelination in vitro. Combined local insulin and PTEN siRNA hind paw injections improved abnormalities in chronic experimental diabetic polyneuropathy, including sensory axon loss, independently of glycemia.

Background Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events. Objectives To categorise contraindications to sclerotherapy based on the available scientific evidence. Methods An international, multi-disciplinary panel of phlebologists reviewed the available scientific evidence and developed consensus where evidence was lacking or limited. Results Absolute Contraindications to sclerotherapy where the risk of harm would outweigh any benefits include known hypersensitivity to sclerosing agents; acute venous thromboembolism (VTE); severe neurological or cardiac adverse events complicating a previous sclerotherapy treatment; severe acute systemic illness or infection; and critical limb ischaemia. Relative Contraindications to sclerotherapy where the potential benefits of the proposed treatment would outweigh the risk of harm or the risks may be mitigated by other measures include pregnancy, postpartum and breastfeeding; hypercoagulable states with risk of VTE; risk of neurological adverse events; risk of cardiac adverse events and poorly controlled chronic systemic illness. Conditions and circumstances where Warnings and Precautions should be considered before proceeding with sclerotherapy include risk of cutaneous necrosis or cosmetic complications such as pigmentation and telangiectatic matting; intake of medications such as the oral contraceptive and other exogenous oestrogens, disulfiram and minocycline; and psychosocial factors and psychiatric comorbidities that may increase the risk of adverse events or compromise optimal treatment outcomes. Conclusions Sclerotherapy can achieve safe clinical outcomes provided that (1) patient-related risk factors and in particular all material risks are (1a) adequately identified and the risk benefit ratio is clearly and openly discussed with treatment candidates within a reasonable timeframe prior to the actual procedure; (1b) when an individual is not a suitable candidate for the proposed intervention, conservative treatment options including the option of ‘ no intervention as a treatment option’ are discussed; (1c) complex cases are referred for treatment in controlled and standardised settings and by practitioners with more expertise in the field; (1d) only suitable individuals with no absolute contraindications or those with relative contraindications where the benefits outweigh the risks are offered intervention; (1e) if proceeding with intervention, appropriate prophylactic measures and other risk-mitigating strategies are adopted and appropriate follow-up is organised; and (2) procedure-related risk factors are minimised by ensuring the treating physicians (2a) have adequate training in general phlebology with additional training in duplex ultrasound, procedural phlebology and in particular sclerotherapy; (2b) maintain their knowledge and competency over time and (2c) review and optimise their treatment strategies and techniques on a regular basis to keep up with the ongoing progress in medical technology and contemporary scientific evidence.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing novel coronavirus disease 2019 (COVID-19) appeared in Wuhan, Hubei province, China in late December 2019 and has rapidly spread worldwide. In this study, a total of 267 genomes of SARS CoV-2 viruses collected from 28 Center for Diseases Controls and hospitals in different provinces in Northern and Central Vietnam from January 2020 to April 2021 were sequenced and analyzed their diversity using the iSeq 100 platform. Results showed that most of the virus samples originated from domestic community patients (84.3%). Variable variants of SARS CoV-2 virus were detected within the three pandemic waves. The very first variant of SARS-CoV-2 in Viet Nam in January 2020 was 19B (Nextstrain Clade), 3/8 of the variants were from the international arrival samples group. In the first and second pandemic waves, lineage 20B was the most prevalent and this variant was found in Da Nang, Hai Duong and Thai Binh with a large number of patients. In the third wave of the COVID-19 pandemic, lineage 20I was the most dominant and detected in all provinces where the outbreak occurred. Five COVID-19 clusters caused by SARS-CoV-2 variant 20I were also found during this time.

Background: This study evaluates mortality and intermediate outcomes of the arterial switch operation (ASO) for transposition or Taussig-Bing anomaly with single sinus coronary artery (CA) anatomy in a high-volume cardiac program in Vietnam. Methods: We retrospectively reviewed and performed risk factor analysis pertaining to 41 consecutive patients who presented with single sinus CA anatomy and who underwent ASO from January 2010 to December 2016 in our center. Results: The median age at operation was 43 days [interquartile range (IQR): 20-65] and the median weight was 3.6 kg (IQR: 3.4-4.0). Four in-hospital deaths (9.8%), of which one was related to coronary insufficiency. There were no late deaths, with a median follow-up time of 7.2 years. Survival for all patients with single sinus CA was 90.2% at 1 year and remained constant at 5 years and 10 years after ASO. The presence of a coexisting aortic arch anomaly was the only risk factor for overall mortality identified in this study (hazard ratio: 8.66, P = .031, 95% confidence interval: 1.21-61.92). There were three cardiac reoperations. Freedom from reintervention after ASO for patients with single sinus CA at 1 year, 5 years, and 10 years were 97.3%, 91.9%, and 91.9%, respectively. Interestingly, among all patients undergoing ASO during this time period (n = 304), single-sinus CA anatomy was not a risk factor for overall death ( P = .758). Conclusions: In a high-volume cardiac program in a lower middle-income country like Vietnam, ASO can be safely performed with single sinus CA anatomy, irrespective of the presenting coronary anatomy.

The strict measures of social distance to curb the outbreak of COVID-19 have resulted in the physically prolonged closure of educational institutions. Accordingly, shifting the whole school system to the virtual learning environment via online learning platforms such as Zoom and Microsoft Teams is one of the most prominently favored solutions among the attempts made by governments to guarantee the continuity of the teaching-learning process. The current study aimed at investigating how EFL students perceive the adoption of Microsoft Teams during COVID-19 as well as proposing some suggestions to improve online learning via this platform. The mixed-method design was adopted to fulfil the purposes of the study. The participants include 151 EFL students at a state university in Vietnam. The questionnaire which was developed based on Technology Acceptance Model and the semi-structured interviews were employed as the data collection instruments. The findings indicated that the EFL students’ perceptions of Microsoft Teams were generally positive. Also, a large number of suggestions were put forward to educational institutions, teachers and students for better adoption of this online platform in the future.

The paper aims to assess the changing trend of monthly rainfall and minimum monthly rainfall in Binh Dinh province by the Mann-Kendall test method and the Theil-Sen trend in the period 1981 - 2919. The results show that: With a statistical significance of 5%, rainfall tends to increase in January at Hoai Nhon and Binh Tuong stations with an increase of 1.2 - 1.3 mm\year and tends to increase in August at An Nhon station with an increase of 1.7 mm\year but tends to decrease in June at Quy Nhon station with a decrease of 1.6 mm\year. The total rainfall in the minimum months (from January to April) tends to increase at Hoai Nhon and Quy Nhon stations with an increase of 2.3 - 2.5 mm\year. Monthly rainfall and total monthly rainfall at the remaining stations do not satisfy the condition P-value ≤ 0.05, therefore, hypothesis H0 is accepted as a trendless series.

The paper has developed an optimization procedure to design the rotor lamination and magnetic sizes. The average torque is improved by changing the thickness of the outer bridge and magnetic width. Various metamodels with the best prediction performance generated for each of the multi-objective functions and constraints have been selected. By applying a multi-objective genetic algorithm, several optimal solutions have to be considered to compare with those of the initial model. Hence, the multi-objective optimization method for designing the interior permanent magnet (IPM) motor is presented to obtain the high reliability and maximum torque. This development allows to estimate the back electromotive force (EMF), magnetic flux density and electromagnetic torque. In addition, the torque ripple evaluated via the analytical Matlab program is coupled to the finite element method and genetic algorithm optimization. Rotor laminations are finally stamped and assembled into the motor to verify the EMF under the rated load and no load test.

In this article, the influence of some factors on the characteristics of metallized incendiary mixtures (pyrogels) was studied. The pyrogel-type contains benzene, polyisobutylene, magnesium, aluminum-magnesium alloy, sodium nitrate, and different additives. It is shown that the molecular weight of polyisobutylene, the amount of aluminum-magnesium alloy, the particle size of metal combustibles, and the amount and type of polyester threads have different effects on the heat of combustion, flash point, burning rate, flame height, and adhesion to the material surface. The optimal pyrogel contains 38-40% thickened benzene - PIB with molecular weight 175000-225000, 25-27% aluminum-magnesium alloy with particle size ≤ 160µm, 10-12% magnesium powder with particle size ≤ 180µm, 15% sodium nitrate, 8% phenol-formaldehyde resin and 1.5% (over 100%) 3D polyester threads.

This study evaluated the groundwater levels (GWLs) and groundwater quality of Can Tho city (CTC) using statistical analysis and a Groundwater Quality Index (GWQI). In addition, the groundwater recharge potential from rainfall was investigated for the period 2001-2009. The results show that GWLs decreased rapidly in the period 2000-2010 and gradually in the period 2012-2018 in both the Middle-upper Pleistocene (qp2-3) and Upper Pleistocene (qp3) aquifers. This is due to excessive withdrawals, especially to meet the demands of production facilities in the city’s industrial zones. In this regard, Decree No. 2946/UBND-KT of the People’s Committee of CTC was issued and enacted in 2012, which resulted in a marked reduction in withdrawals and contributed to GWL stabilization. Groundwater quality in CTC was found to be mainly affected by coliform in both dry and wet seasons. However, groundwater quality improved during the wet season with the dilution of rainfall, as shown by the GWQI values. In addition to groundwater recharge from rainfall, other socio-economic factors such as urbanization, industrialization, and the influence of the Bassac River on recharge potentials should be further investigated.

Coal-fired power plant fly ash is a global environmental concern due to its small particle size, heavy metal content, and increased emissions. Although widely used in concrete, geopolymer, and fly ash brick production, a large amount of fly ash remains in storage sites or is used in landfills due to inadequate raw material quality, resulting in a waste of a recoverable resource. Therefore, the ongoing need is to develop new methods for recycling fly ash. The present review differentiates the physiochemical properties of fly ash from two coal combustion processes: fluidized bed combustion and pulverized coal combustion. It then discusses applications that can consume fly ash without strict chemical requirements, focusing on firing-associated methods. Finally, the challenges and opportunities of fly ash recycling are discussed.

The creation of biologically inspired artificial lipid bilayers on planar supports provides a unique platform to study membrane-confined processes in a well-controlled setting. At the plasma membrane of mammalian cells, the linkage of the filamentous (F)-actin network is of pivotal importance leading to cell-specific and dynamic F-actin architectures, which are essential for the cell’s shape, mechanical resilience, and biological function. These networks are established through the coordinated action of diverse actin-binding proteins and the presence of the plasma membrane. Here, we established phosphatidylinositol-4,5-bisphosphate (PtdIns[4,5]P2)-doped supported planar lipid bilayers to which contractile actomyosin networks were bound via the membrane–actin linker ezrin. This membrane system, amenable to high-resolution fluorescence microscopy, enabled us to analyze the connectivity and contractility of the actomyosin network. We found that the network architecture and dynamics are not only a function of the PtdIns[4,5]P2 concentration but also depend on the presence of negatively charged phosphatidylserine (PS). PS drives the attached network into a regime, where low but physiologically relevant connectivity to the membrane results in strong contractility of the actomyosin network, emphasizing the importance of the lipid composition of the membrane interface.

Introduction. The lack of access to behavioral health care, trends in behavioral health issues, and the impact of social determinants of health underlie the need for behavioral health reform in Kansas. However, stakeholders may affect progress toward behavioral health reform. This study examined stakeholders’ attitudes toward behavioral health reform. Methods. This study analyzed data from a survey administered to elected officials, members of health advocacy groups, state employees, and payers in Kansas. Main outcome measures included attitudes toward primary care and behavioral health integration; the perceived benefit of certain behavioral health and social determinants of health policies; and the perceived performance of the primary care and behavioral health care systems in Kansas. Results. Although stakeholders supported most policies that facilitate primary care and behavioral health integration, elected officials and payers were less likely to support financial incentives for primary care practitioners who treat gender dysphoria than health advocates and state employees. Payers perceived legislation to improve insurance coverage for behavioral health issues as less beneficial than state employees and health advocates. And elected officials perceived legislation to address various social determinants of health as less beneficial than health advocates. Conclusions. Preliminary findings indicate may reflect both the barriers and facilitators to behavioral health reform in Kansas. However, several limitations undermined the generalizability of these findings. Future studies should consider more representative sample sizes, additional variables in behavioral health and social determinants of health policies, and more comprehensive, validated measures.

Reformatory students are those whose deviant behaviors and habits prevent them from receiving education under normal educational conditions. These students frequently lead a careless, undisciplined lifestyle, being unwilling to work and learn eager to play and demanding. Therefore, when they are admitted to reformatories with severe study and lifestyle requirements, they have great psychological difficulty adjusting to their new environment. Students’ psychological issues in adapting to reformatory learning and living regimes are difficult and psychological deficits make it challenging for students to adapt to reformatory learning and living conditions. In Vietnam, 665 students from reformatory schools were polled to determine the causes of psychological issues. According to the findings, a variety of elements contribute to students’ psychological difficulties. Individual student conditions such as health, awareness, attitudes and actions as well as inappropriate habits, living without goals or aspirations, etc. are on the subjective side of the equation. On the objective side are the students’ conditions, family, education and psychological obstacles brought on by less-than-ideal circumstances which will make it more difficult for community students to adapt. Both the new school and society must pay more attention to reformatory students in order to establish the conditions necessary for successful integration into the new school and ultimate readmission into society for these students.

The Pneumatic Artificial Muscle (PAM) is a promising actuator for developing the human-robot interaction system. However, modeling and controlling PAM-based actuators are a significant difficulty due to the inherent uncertainty and hysteresis of PAM. Besides, the control approach of a PAM-based system also deals with unknown disturbances that always exist in any system. This study developed a sliding mode controller that employs an adaptive law to deal with issues and improve control performance. Furthermore, the stability of the proposed controller is proven based on the Lyapunov stability criterion. Finally, through a series of tests, the effectiveness of the proposed control approach is verified.
