Status of Ethnic Minority Children's Emotional and Social Skills in the Northern Regions of Vietnam

In the content of child development and capacity building, the most important content is emotional education - social skills for children. Emotional competencies - social skills are the most important segments in forming personality for preschool children, contributing to promoting the positive development of young individuals and society. Emotional- social skills of preschool children play an important role and are a prerequisite for the comprehensive development of the child's personality, helping children to have feelings, moral standards, and experiences in knowing what to do and should not do in order to have a correct and standard manners. However, the performance of children in schools in the northern mountainous region of Vietnam is still at a low level. The article also reveals difficulties affecting children's emotional-social skills such as the lack of attention from parents, the environment for children to practice, the lack of experience and children's underdeveloped common language. This article is completed based on the survey results and face-to-face interviews to find out the most effective solutions to educate children in the northern mountainous areas of Vietnam. The paper found that children's social and emotional skills need to be fostered by parents as well as by school because they play an important role in their development.
Does Family Communication Pattern Predict Suicide Ideation and Attempt? A Longitudinal Study of Adolescents in Indonesia

Suicide is one of leading causes of death among adolescents around the world, including in Indonesia. Dysfunctional familial relationships are major risk factors for suicidal behavior, and Indonesia’s unique culture and values shape the communication pattern and power dynamics among parents and adolescent children. This school-based longitudinal study aimed to determine the prevalence of suicide attempts and suicidal ideation in urban Jakarta adolescents and to examine the association with family communication pattern. The Family Communication Pattern Questionnaire (FCPQ) and Youth Risk Behavior Survey (YRBS) were completed by 531 students from five high schools in Jakarta selected by multistage random sampling. Associations between YRBS and FCPQ responses were analyzed using logistic regression. The YRBS revealed higher prevalence of suicidal ideation (8.1%) and attempt (5.5%) than in previous studies from Indonesia. In contrast to several previous reports, however, family communication pattern was not a strong predictor of suicide attempt by adolescents. Conversation orientation with the mother was a significant predictor of suicidal ideation according to logistic analysis (p<.05). Adolescents reporting suicidal ideation as well as those with a history of suicide attempt should be referred for professional treatment.
Floating population and demand for movie theaters in metropolitan cities

Using novel subway passenger and theater information data, we examine how the demand for a theater in a densely populated metropolitan area is affected by the floating population around the theater. We find that the floating population positively affects the demand for a theater and its impact becomes significant and larger in magnitude than the impact of resident population for theaters located in the largest metropolitan cities. Our findings suggest that taking the floating population as well as the resident population into account is necessary for measuring local market size accurately, especially for theaters located in the largest metropolitan cities.
Baltic Journal of Health and Physical Activity Baltic Journal of Health and Physical Activity Emitter and tourist destination in Romania Emitter and tourist destination in Romania

Abstract Background: The need to identify, analyze and establish relationships between destinations and tourist emission, as terminus points between which the tourist circulation takes place, arises from the structural and functional complexity of tourism, on the one hand, and from its unprecedented expansion, on the other hand. Material and methods: Within the present study, which concerned Romania as a tourist destination, a number of specific, determinative indicators for the emission areas and the tourist destinations were identified and analyzed. Results: The obtained results focused on the analysis of: capacity, hierarchy, spatial distribution and establishment of relations between tourist emission / reception centers. They pointed out that Bucharest is the most important center of emission and tourist destination, followed by big urban centers of Constan ț a, Brasov, Mangalia, Cluj, Sibiu, Ia ș i, etc., with some oscillations in what supposes their capacity of emission respectively tourist reception. Conclusions: The spatial distribution of the tourist emission-reception centers at the level of Romania is a discontinuous, individualized nuclei of utmost importance (the mountain area, the Black Sea coast and the Bucharest area) and the poor areas in infrastructure and tourist objectives, which determines a low flow of tourists. abstract Background: ‪‪The need to identify, analyze and establish relationships between destinations and tourist emission, as terminus points between which the tourist circulation takes place, arises from the structural and functional complexity of tourism, on the one hand, and from its unprecedented expansion, on the other hand.

The Ecosystem Penalty: Value Creation Technologies and Incentive Misalignment

When are the incentives of a business ecosystem’s participants aligned with its growth? How is the technology of value creation affecting this alignment? To answer these questions we formally model how value creation determines value capture in a business ecosystem. We find that alignment is typically imperfect compared to an integrated benchmark, highlighting an “ecosystem penalty” whereby participants’ returns to value creation are lower than that of the ecosystem. The occurrence of this penalty depends on whether the technology is loosely coupled (value additive in inputs), exhibits bottlenecks (value constrained by the weaker input), or is strongly supermodular (value multiplicative in inputs). Contrary to conventional wisdom, we find it can be severe for the participants who are constraining the system the most.
Solution structures of some phenothiazine derivatives Cu(II) complexes

Four Cu(II) complexes of phenothiazine derivatives with antibacterial activity have been synthesised and their solution structure has been characterised using EPR and optical spectroscopy. The species are four- and five-co-ordinated in distorted arrangements, either as monomers or dimers, depending of the counterion. The covalence coefficients that characterise the first co-ordination sphere are obtained using the spin Hamiltonian parameters and the electronic transition energies in a ligand field approach.
Unsteady bioconvection Darcy‐Forchheimer nanofluid flow through a horizontal channel with impact of magnetic field and thermal radiation

Unsteady bioconvection Darcy‐Forchhiemer nanofluid flow is considered in the current investigation in the presence of micro‐organisms. The flow is exposed to thermal radiation and a uniform magnetic field in a horizontal channel. The impacts of Brownian motion and thermophoresis are also considered for the flow problem. The unsteady governing equations are modeled and transformed into a nondimensional form by employing a suitable group of similar variables. The solution of the modeled equations is determined by the semianalytical method homotopy analysis method. The features of flow characteristics such as temperature, concentration, velocity, and the motile micro‐organism distributions in response to the variations of the emerging parameters are simulated and examined in detail. Among the many results of the study, it is found that velocity upsurges with rising values of the unsteadiness parameter while declining with growth in the magnetic, inertial, and porosity parameters. Temperature augments with growing estimations of Brownian, unsteadiness, and radiation parameters and declines with enhancing values of Prandtl number. Amassed estimations of the Brownian factor reduce the concentration of nanoparticles while growing values of thermophoresis, unsteadiness parameters, and Schmidt number increase it. Moreover, the motile micro‐organism profile is a reducing function of the bioconvection Lewis numbers, Peclet, and bioconvection concentration difference parameter.
Modeling Analysis of Thermal Lesion Characteristics of Unipolar/Bipolar Ablation Using Circumferential Multipolar Catheter

The circumferential multipolar catheter (CMC) facilitates pulmonary vein isolation (PVI) for the treatment of atrial fibrillation by catheter ablation. However, the ablation characteristics of CMC are not well understood. This study uses the finite element method to conduct a comprehensive analysis of the ablation characteristics of multielectrode unipolar/bipolar (MEU/MEB) modes of the CMC. A three-dimensional computational model of the CMC, including blood, myocardium, connective tissue, lung, and muscle, was constructed. The method was validated by comparing the results of an in vitro experiment with the simulation. Both ablation modes could create contiguous effective lesions, but the MEU mode created a deeper and broader lesion volume than the MEB mode. The MEB mode had an overall higher average temperature field and allowed faster formation of the effective contiguous lesion. The lesion shape tended to be symmetric and spread downward and superficially in the MEU mode and MEB mode, respectively. Results from the simulation for validation agreed with the in vitro experiment. Different ablation trends of the MEU and MEB modes provide different solutions for specific ablation requirements in clinical applications. The MEU mode suits transmural lesion in thick tissue around pulmonary veins (PVs). The MEB mode profits fast and durable creation of circumferential PVI. This study provides a detailed performance analysis of CMC, thereby contributing to the theoretical knowledge base of application of PVI with this emerging technology.
Models of Application of IT in Teaching in the Condition of Transformation of the Education System and Searching for a New Paradigm

Humanity is on the verge of the fourth industrial revolution in anticipation of global changes. A global reform of education is expected - from the change of the paradigm itself and the creation of a new teaching methodology to the creation of new forms, methods and teaching methods. However, there are many difficulties and unsolved scientific problems in this direction. For example, what the “education paradigm” is, how it is related to the teaching methodology, the ways of transforming the education system, and its initial and final goals are not defined. The article discusses new models of the application of information technologies in teaching, which can be used as a kind of basis for finding answers to these questions.
Modeling and Forecasting of Tourism Demand in Malaysia

The pattern of foreign tourist demand to Malaysia is analysed and forecasted using time series method and non-linear technique. There are nine selected countries that contribute a lot to tourist arrivals to Malaysia, namely Australia, Brunei, China, Indonesia, India, Japan, the Philippines, South Korea, and the United Kingdom. Box-Jenkins time series method and Singular Spectrum Analysis are conducted and compared to study the best model to forecast the foreign tourist demand to Malaysia. Monthly data of tourism arrival in 1990 to 2014 were used and the forecasting were compared with 2015. Based on the results obtained, the forecasting model of Box-Jenkins time series method is the best model based on the percentage accuracy in forecasting the tourist demand to Malaysia.
Alloying effect-induced electron polarization drives nitrate reduction to ammonia

Electrocatalytic conversion of nitrate (NO3-) to ammonia (NH3) holds significant potential in the control of nitrogen oxide (NOx) from stationary sources. However, previous studies on reaction intermediates remain unclear. Here we report that Pd/Cu2O hybrids with mesoporous hollow sphere structure show high selectivity (96.70%) and Faradaic efficiency (94.32%) for NH3 synthesis from NO3-. Detailed characterizations demonstrate that (1) Pd enables electrons transfer (Pd 3d → Cu 3d) and makes the polarization of Cu 3d orbitals by forming partial PdCu alloys, which makes Pd electron-deficiency but offers empty orbits to adsorb NO3-; (2) electron-rich Cu are more conducive to the occurrence of NO3- reduction. The mutual confirmation of online differential electrochemical mass spectrometry and density functional theory calculations demonstrates that PdCu alloys block the generation of *NOH intermediate and facilitate the formation of *N, finally leading to a higher catalytic performance.
Applying “Stages of Readiness to Change” Model to Dentists’ Decisions to Participate in Medicaid: An Exploratory Study

Background The Stages of Readiness to Change (SOC) behavioral model describes behavior change as a process and distinguishes individuals based on their current behavior and readiness to change that behavior. SOC can be used to improve dentists’ participation in a state public dental benefit program (Medicaid) by targeting them at different SOC with interventions, strategies, and tools tailored to those stages. Therefore, this study assessed the usefulness of using SOC to describe dentists’ attitudes towards and participation in Medicaid. Dentists’ participation in Medicaid is of interest to policymakers, and this study demonstrates a method to identify potential opportunities for intervention. Methods A modified SOC algorithm used data from a periodic survey of Iowa Dentists to categorize dentists (N=514) into: 1) pre-contemplation, 2) considering participation (SOC contemplation and preparation), 3) acting (SOC action and maintenance), and 4) risk of relapse (at risk for discontinuing participation). The four SOC stages were compared using ANOVA and post hoc Tukey’s test among: practice characteristics, Dentists Altruism scale, Attitude about Program Administration scale, Attitude about Medicaid patients scale and Perception of Importance of Medicaid Problems scale. Results Among survey respondents, 36% were categorized as pre-contemplation, 6% were considering Medicaid participation, 12% were acting as Medicaid providers with minimal risk of relapse, and 46% were participating and at risk of discontinuing. Dentists’ attitudes towards program administration, Medicaid patients, and access to care varied across the SOC cycle. Conclusion Nearly, 46% dentists in this analysis were identified as at risk of discontinuing participation – a much larger proportion than dentists considering Medicaid participation. Categorizing dentists using this approach has important implications for programmatic interventions. For example, policymakers targeting our study population could focus their efforts on reducing the likelihood of dentists dropping out of the program, with less emphasis targeting dentists in the precontemplation stage.
Multiscale Modeling of Multiphase Fluid Flow

Abstract : A multiscale modeling approach including molecular dynamics and computational fluid dynamics was carried out address the disparate time and length scales involved in modeling fluid flow and heat transfer. Molecular dynamics simulations were carried out to provide a molecular level understanding of the transport properties of surfactant aqueous solutions; the solvent effects on the solubility of the thermal decomposition reaction products of ammonium carbamate; and the temperature dependence of the accommodation coefficient of liquid octane. Computational fluid dynamics methods were used to investigate the heat transfer process in open-cell micro-foam with phase change material; enhancement of natural convection for fluid media in an enclosure; and thermal effects on vortex-induced vibrations.
An Aerosol-Liquid-Solid Process for the General Synthesis of Halide Perovskite Thick Films for Direct Conversion X-Ray Detectors

Medical X-ray computed tomography requires fast imaging at a low dose rate and in a large area. Halide perovskites have shown high potential for X-ray detection, but a pressing challenge is the current lack of low-cost methods for large-scale fabrication of high-quality thick perovskite films. Here we demonstrate and elucidate an aerosol-liquid-solid process to enable continuous growth of uniform halide perovskites films at low temperature over a large area of 100 cm2, which are vertically monolithic and monocrystalline, and thus beneficial to carrier transport. Direct conversion X-ray detectors based on the representative CsPbI2Br films in conjunction with a deliberated, interface-engineered C-electrode have realized an unprecedented sensitivity (≥1.48×105 μC Gyair−1cm−2). We have further demonstrated the high-resolution radiographic imaging capability of these films. These results lay the groundwork for large scale application of halide perovskites in radiation detectors.
Antibiotic Prescribing Errors in Patients Discharged From the Pediatric Emergency Department

Objectives The pediatric emergency department (PED) is an especially high-risk setting for medication errors. Several factors contribute to this risk including the need to provide care to complex patients who are unknown to staff, the frequent use of verbal orders, and the necessity of weight-based dosing. This investigation sought to assess one potentially error-prone event, antibiotic prescriptions written for patients being discharged from the PED, and to characterize the occurrence of medication errors to identify opportunities for improvement. Methods This was a retrospective study of pediatric patients seen at a large academic medical center PED. All prescriptions written for an antibiotic for patients 18 years or younger that were discharged from the PED from 2015 to 2018 were evaluated for errors in directions, indication, dose, quantity, and refills. Because antibiotic dosing can vary based on indications, only disease states with guideline-specific dosing recommendations were evaluated for dosing errors. Results A total of 11,815 antibiotic prescriptions were analyzed for patients discharged from the PED, and 1986 (16.8%) errors were identified. Of all the prescriptions reviewed, 517 (4.4%) contained an incomplete prescription error. Discharge prescriptions written by off-service physicians were more likely to contain incomplete prescription errors (5.1%) when compared with emergency medicine physicians (3.9%; P = 0.022). A dosing error rate of 18.5% (1469 prescriptions) was identified for the 7930 disease state-specific prescriptions reviewed. Underdosing errors were significantly more common (51.6%) than overdosing errors (29.3%; P < 0.0001). Among the different agents, there was noted to be a significant difference in the antibiotics most commonly involved in dosing errors (P < 0.0001). Additionally, there was also a significant difference in the incidence of dosing errors between different disease states (P < 0.0001). No significant difference was found in the incidence of dosing errors across physician specialties (P = 0.872). Conclusions We identified 1986 (16.8%) total errors in this analysis of antibiotic prescriptions written on discharge from the PED. Among the disease states evaluated, dosing errors were identified in 18.5% of prescriptions with the most common error being underdosing. Literature evaluating pediatric prescription errors, and specifically antibiotic discharge prescriptions, is quite limited. Further investigation is necessary in this area, and strategies should be developed leveraging technology, enhancing education, and using pharmacy personnel to help reduce antibiotic prescribing errors for patients discharged from the PED.
