Employee engagement and job personal resources among nurses in Thailand: The mediating role of psychological conditions

High employee turnover has accounted for the shortage of manpower in nursing. It has become a worldwide issue in many countries including Thailand. This study aims to examine the relationships between job-personal resources and work engagement and the mediating role of psychological conditions in the relationship between job-personal resources and work engagement. The study was conducted in private hospitals of health tourism in Bangkok, Thailand. The sample consisted of 361 registered nurses. Questionnaires were used to collect the data on job-personal resources, work engagement, and psychological conditions. The findings reveal that the level of nurses’ work engagement is above moderate. The result of hierarchical multiple regressions analysis shows significant direct relationship between job-personal resources (self-efficacy, perceived supervisor support, and reward & recognition) and work engagement. Psychological conditions are found partially mediate the relationship between job-personal resources and work engagement. The results of this study provide decision makers, policy makers, and practitioners in the medical tourism industry with an understanding of the factors (job - personal resources and psychological conditions) that influence work engagement among nurses in private hospitals. Subsequently appropriate measures could be designed to enhance nurses’ work engagement and reduce their intention to quit. The findings of the study could contribute to the enhancement of the existing literature in the area of work engagement. Limitations of the study, recommendations and future research are also provide

The Impact of The 101s: A Guide to Positive Discipline Teacher Training on Teacher Interaction Practices, Teacher-Child Relationship Quality, School Adjustment, and Academic Outcomes in Kindergarten Classrooms in Bangkok, Thailand

While a great body of research evidence in the United States shows the impact of positive teacher interactions on teacher-child relationship quality and beneficial school outcomes for young children, it is not clear how Thai children would respond to the kind of interactional and social-emotional practices of American teachers. In this research, teacher training through The 101s: A Guide to Positive Discipline (The 101s, Kersey, 2006) was implemented in kindergarten classrooms in Bangkok, Thailand. The purpose of the study was (a) to investigate the impact of The 101s teacher training on changes in teacher interaction practices, teacher-child relationship qualities, and children\u27s school adjustment, using a series of multivariate of covariance analyses (MANCOVA), and (b) to examine how these changes impact children\u27s academic achievement, using bivariate correlation analyses. The sample of this study consisted of 20 kindergarten teachers and 164 three to four-year old students enrolled in the ten classrooms in two private elementary schools located in Chatuchak district during the month of May 2009. The sample was divided into three groups. First, The 101s teacher training group in which the teachers received The 101s training consisted of 6 teacher participants and 59 children participants. Second, The 101s parent training group in which the parents received The 101s training but the teachers received no training consisted of 6 teacher participants and 50 children participants. Third, control group in which neither teachers nor parents received The 101s training consisted of 8 teacher participants and 55 children participants. The results of this study showed that The 101s teacher training intervention described in this study was associated with positive changes in the teacher interaction practices, teacher-child relationships, and children\u27s school adjustment. Additionally, The 101s teacher training resulted in positive correlations among the use of positive principles in The 101s, close teacher-child relationships, school liking, cooperative participation, self-directedness, language skills, and critical thinking skills. The results suggest that the cultural difference would not be a barrier to changing Thai teachers\u27 interaction practices. The implications for teachers, schools, and educational policy mandates in Thailand, limitations, and suggestions for future research are discussed

Effect of Process Parameters on Yield of Biofuel Production from Waste Virgin Coconut Oil

This research aimed to determine the influence of process parameters on yields of biofuel production by hydrocracking of waste virgin coconut oil using HZSM-5 zeolite catalyst and to determine statistical relationship of yields of biofuels with the parameters by Pearson’s correlation. The various operating parameters in batch reactor were a reaction temperature (350-400°C), an initial hydrogen pressure (20-40 bar), and a reaction time (1-3 h). The highest yields of gasoline (6.79 wt%) and kerosene (31.38 wt%) were achieved under a temperature at 400°C, initial hydrogen pressure at 40 bar, and a reaction time of 3 h. The highest yield of diesel of 58.62 wt% was achieved at a reaction time of 1 h under temperature 400°C and initial hydrogen pressure 40 bar. The experimental data were analyzed by input-output model with the coefficient of determination (R2) of yield prediction ranging from 0.86 to 0.92. The Pearson’s correlation coefficients show strong dependence of reaction temperature and time on hydrocarbon chains of various length. Yields of shorter hydrocarbon chains such as gasoline and kerosene required higher reaction temperature and longer reaction time and vice versa. Pressure dependence on yields of biofuels was insignificant

Urban Air Mobility System Testbed Using CAVE Virtual Reality Environment

Urban Air Mobility (UAM) refers to a system of air passenger and small cargo transportation within an urban area. The UAM framework also includes other urban Unmanned Aerial Systems (UAS) services that will be supported by a mix of onboard, ground, piloted, and autonomous operations. Over the past few years UAM research has gained wide interest from companies and federal agencies as an on-demand innovative transportation option that can help reduce traffic congestion and pollution as well as increase mobility in metropolitan areas. The concepts of UAM/UAS operation in the National Airspace System (NAS) remains an active area of research to ensure safe and efficient operations. With new developments in smart vehicle design and infrastructure for air traffic management, there is a need for methods to integrate and test various components of the UAM framework. In this work, we report on the development of a virtual reality (VR) testbed using the Cave Automatic Virtual Environment (CAVE) technology for human-automation teaming and airspace operation research of UAM. Using a four-wall projection system with motion capture, the CAVE provides an immersive virtual environment with real-time full body tracking capability. We created a virtual environment consisting of San Francisco city and a vertical take-off-and-landing passenger aircraft that can fly between a downtown location and the San Francisco International Airport. The aircraft can be operated autonomously or manually by a single pilot who maneuvers the aircraft using a flight control joystick. The interior of the aircraft includes a virtual cockpit display with vehicle heading, location, and speed information. The system can record simulation events and flight data for post-processing. The system parameters are customizable for different flight scenarios; hence, the CAVE VR testbed provides a flexible method for development and evaluation of UAM framework

The present study sought to (1) assess the needs in the development of the teacher training curriculum on providing learning experiences for promoting social development among persons with autism spectrum disorder (ASD), (2) develop the curriculum, and (3) examine its effectiveness. A mixed-method approach and research and development were adopted. The data were collected during July 2022–April 2023. The results are reported: 1. A review of documents, literature and related studies showed that teacher preparation was required for promoting persons with ASD’s social development. Additionally, the survey indicated that the school directors’ primary need for self-improvement was the frequency of attending training programs (PNIModified = 0.54), while that of the teachers was knowledge and understanding of promoting social development (PNIModified = 0.21). Also, the school directors’ strongest need in providing learning experiences was continuous promotion of social development (PNIModified = 0.47), and that of the teachers was implementation of learning activities based on lessons plans (PNIModified = 0.21). 2. The developed curriculum comprised eight components: rationale, objectives of the curriculum, contents, training activities and methods, training materials, durations, venues, and measurement and evaluation. Concerning its quality, the curriculum achieved a high level of suitability (x = 4.38, S.D. = 0.16). 3. After the curriculum implementation, the teachers achieved higher post-training scores (x = 22) than their pre-training scores (x = 17.20) and were most satisfied (x = 4.71, S.D. = 0.08). Provision of learning experiences achieved a mean score of 84.67%

Error compensation and uncertainty evaluation of CMMs based on kinematic error models and gaussian processes

This thesis was submitted for the degree of Masters of Philosophy and awarded by Brunel University London.Given the increasing demand for precision engineering applications, the evaluation of measurement error and uncertainty has been the focus of intensive research to meet the requirements of precision manufacturing processes. Systematic errors of mechanical components affect the accuracy of the production parts. It is therefore best to analyse the geometric accuracy of machine tools before production processes begin. This proposed method is based on simulation in the MATLAB programme, which investigates the influence of the geometric errors of the Coordinate Measuring Machine (CMM) on the calibration. The advantages of this measurement procedure are reduced physical measuring times, reduced measurement uncertainties as well as volumetric measurement, and compensation for CMM geometric errors. In this research, theoretical modelling of the local, kinematic error model and the Gaussian Process (GP) model are presented and explored in depth. These proposed methods are simulations providing an integrated virtual environment in which user can generate the inspection path planning for specific tasks and evaluate the errors and uncertainty associated with the measurement results, all without the need to perform a number of physical CMM measurements. The estimated errors and uncertainty can serve as rapid feedback for users before performing actual measurements or as a prior evaluation of the results of the CMM calibrations. The estimation of CMM geometric errors are usually described using 21 kinematic errors which consist of three positional and three rotational error functions for each of the three axes, along with three squareness errors. This assumes that the method to estimate of these kinematic errors can be generated by performing an artefact measurement such as for a hole or a ball plate in the numbers of the positions of the CMM working region and then matching the kinematic errors to the measured changes in artefact geometry. The process validation of a local, kinematic error model and a GP model has been determined with the design and analysis of CMM measurement using a ball plate as an artefact, calculating the percentage error to compare their effective results. This research project has led to the following contribution to knowledge: Mathematical model development for making effective choices regarding the local, kinematic error model and GP model is performed and formulated; this is verified by particular kinematic errors of the CMM measurements, presenting high accuracy and reliability of the error and uncertainty evaluation performance. The improvement achieved by the proposed method over the traditional approaches between the simulated datasets and actual CMM data measurements has been demonstrated. The numerical simulations with a well-designed strategy providing accurate estimates of the CMM kinematic errors using only a nominal CMM calibration with a ball plate have been validated and evaluated in both approaches. The influences of kinematic errors affected through the measurement process of the CMM on the calibration have been investigated.Royal Thai Government, Ministry of Sciences and Technology and National Institute of Metrology Thailand (NIMT)
