Item type:Publication, Sustainability awareness, attitudes and actions: A survey of pre-service teachers(2019-01-01); Murphy, ElizabethThe purpose of this study was to survey the awareness, attitudes and actions of Thai, pre-service, industrial-education teachers (N=390) regarding economic, social and environmental sustainability. Survey items were derived from learning objectives provided by UNESCO in relation to 17 sustainable development goals (SDGs). Research questions focused on overall results as well as analyses to determine differences based on program type and year of study. Results showed an average overall higher percentage in the categories of attitudes (90%) and action (91%) than for awareness (69%). The lowest ranked items in the categories of attitudes and action were related to SDG 5, gender equality. Pre-service teachers in year two of their program reported significantly higher levels of awareness than those in their first, third, fourth or fifth year. There were no significant differences for program type. Implications point to the value for higher education institutes, programs and instructors of identifying sustainability issues most relevant to their context in terms of culture and subject area. Results also pointed to the possibility that higher education institutions may be able to address aspects of sustainability through other initiatives (e.g., mental health awareness days) that are not necessarily branded specifically as sustainability issues. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Engineering educators’ perspectives on the feasibility of fostering sustainability through the internet of things(2021-01-01); Murphy, ElizabethThe purpose of this study was to identify the feasibility of integrating the internet of things (IoT) in engineering education (EE) to promote environmental, social and economic sustainability. This purpose is explored through self-report surveys with 113 engineering educators in Thailand. Analysis relied on descriptive statistics and two-way ANOVA. Results revealed high feasibility of integration with less feasibility for social sustainability. There were no significant differences in relation to feasibility and demographic factors such as educators’ years of experience and type of EE. Respondents identified factors that can promote the integration. These were grouped into the following categories: curricula and programs, instructor and student-related factors, administrative and policy factors and technology-related factors. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evaluating the Impact of Sufficiency Economy Philosophy on Sustainable Innovation: A Data-Driven Analysis(2024-12-01); Leekitchwatana, PunneeThis study investigates the factors affecting sustainable innovation within Thailand's Provincial Electricity Authority, a nonprofit organization committed to sustainable energy solutions. With a focus on the Sufficiency Economy Philosophy as a developmental framework, the study examines how SEP principles of moderation, prudence, and resilience contribute to reducing greenhouse gas (GHG) emissions and achieving Sustainable Development Goals (SDGs). The research adopts a quantitative approach to analyze how SEP influences SI in PEA's operations alongside internal and external factors like disruptive leadership, digital transformation, and national sustainability initiatives. Through a series of correlation and regression analyses, the study identifies SEP as a critical component in fostering SI, with values of virtue, risk management, and informed decision-making emerging as influential elements. The findings indicate that integrating SEP's balanced approach to production and consumption facilitates organizational resilience, enabling the PEA to navigate internal and external shocks effectively. Furthermore, the results underscore the necessity of a holistic framework where internal initiatives align with broader cultural and ecological goals. The study highlights SEP's applicability beyond the energy sector, as seen in sustainable efforts in regions like Krabi and Koh Samui, which exemplify SEP-driven approaches toward low-carbon transitions. By leveraging SEP’s sufficiency principles, organizations can strengthen sustainable practices contributing to Thailand's environmental and social well-being. The research calls for further exploration into SEP’s role across sectors, positing that SEP could be a foundational pillar alongside economic, social, and environmental dimensions to drive sustainable innovation across diverse contexts. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Quality, equity, inclusion and lifelong learning in pre-service teacher education(2019-12-01); Murphy, ElizabethSustainable Development Goal 4 (SDG 4) focuses on ensuring inclusive and equitable, quality education and lifelong learning opportunities for all. One of the three means of implementation of SDG 4 targets is SDG 4c which calls on countries and donors to significantly increase the supply of qualified teachers in developing and underdeveloped countries. This emphasis on the supply of teachers is in recognition of the fact that the quality of education ultimately depends on teachers. In general, there is widespread agreement that teacher education has an important role to play in the achievement of the SDG 4 targets. However, there has been limited attention in the literature to SDG 4 in a context of teacher education. This paper aims to contribute to the literature on SDG 4 and teacher education. The paper first presents a conceptual framework pertaining to quality, equity, inclusion, and lifelong learning. Next, the framework is applied to the case of Thailand to identify examples of progress the country is making in support of realization of SDG 4 in teacher education. The framework with the four concepts can be applied by researchers to identify examples of progress on SDG 4 in teacher education in other countries and contexts. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Single-input multiple-output voltage-mode shadow filter based on VDDDAs(2019-05-01); ; ; This paper presents a voltage-mode shadow filter with single-input multiple-output (SIMO) configuration using voltage differencing differential difference amplifiers (VDDDAs). In this design, the low-pass and high-pass output functions of the single-input three-output second order filter are feedback via the voltage amplifier. The proposed filter consists of three VDDDAs, one grounded resistor and two grounded passive elements. The proposed filter uses grounded elements which is attractive for integrated circuit (IC) fabrication. It can simultaneously provide low-pass (LP), high-pass (HP), band-pass (BP), band-reject (BR) and all-pass (AP) responses without matching condition. The proposed circuit has high input impedance. The natural frequency (ω <inf>0</inf> ) and quality factor (Q) can be independently and electronically tuned by changing the external DC bias currents. The effect of the non-ideal and parasitic elements of the VDDDA is studied and investigated. The PSpice simulation and experimental results using CMOS technology and commercially available active devices are given to confirm the workability of the proposed filter. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The role of engineering education for innovation in the 21st century(2019-01-01); Murphy, ElizabethThis conceptual paper first presents a synthesis of the central target and related concepts of five innovation policies from Asia. The paper then identifies how engineering education (EE) can help realise this target. Methods involved online, quantitative, key concept analysis combined with qualitative analysis of units of meaning. Analysis of the policies revealed that the overall target was social and economic prosperity. The prosperity is powered by a capacity for sustainability and inclusivity and by five other sub-categories of capacity as follows: human; relational; research and development; science, technology and innovation and; entrepreneurship and competitive. EE can contribute to social and economic prosperity by helping to build this capacity. Building capacity requires a shift from teaching as telling, to teaching as doing, from transmission of knowledge, to construction of knowledge, from teacher- to learner-centred learning and from didactic teaching to project- and problem-based learning situated in authentic, scientific, social and technological contexts. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Voltage-mode biquad filter using three lt1228s with independent and electronic control of center frequency and quality factor(2023-01-01); ; ; Chanapromma, ChaiyanIn this paper, we describe a voltage-mode (VM) biquad universal filter with one input and four outputs that can be tuned electronically. The filter proposed here is composed of three LT1228 commercial integrated circuits (ICs), seven resistors and two grounded capacitors. The proposed versatile biquad filter simultaneously provides four filtering functions: An inverting low-pass filter (LP), an inverting high-pass filter (HP), a non-inverting bandpass filter (BP), and an inverting notch filter (BR) without changing its topology. Employing two grounded capacitors minimizes the influence of parasitic resistances and capacitances on the proposed circuit's performance. Also, the output voltage nodes of the HP and BR functions have low output impedances. This means that these two filtering functions don't need voltage buffers to connect to other voltage-mode topologies. The center frequency (ω<inf>0</inf>) of the presented filter is electronically controlled and does not influence the quality factor (Q). In addition, they can also be tuned linearly without affecting each other. PSPICE software was used to analyze the modelling results, while a laboratory experiment was performed using LT1228 commercial ICs.
