One of the main factors contributing to climate change and global warming is architecture, which accountsfor about 50% of the country's greenhouse emissions due to construction and the energy needed to keep buildings operational. Sustainable architecture is believed to reduce emissions, andthisapproach has been practisedwithtraditional buildings. In Malaysia, a traditional Malay house (TMH) is one of thetraditional buildings, and it is initially naturally ventilated with occupant-controlled air ventilation to condition the space. Numerous experimental studies claimed that TMHhas demonstrated a good model for contemporary designers to understand climatic and environmental design, building systems, and design adaptability.One of the approaches is to practiseclimatic design strategies. However, there is a lack of study to determine if TMH is still relevant as a sustainable design that can adapt to current climate conditions. Thus, the study aims to investigate the adaptive indoor thermal comfort of a Negeri Sembilan Malay house in a hot-humid climate determinedby the correlation betweenclimatic design strategy and thermal data analysis. This study employed the Predictive Adaptivemodel by executing two stages of fieldwork: i) local climate background and ii) physical measurement (case study description and environmental data). The data were thenanalysed using the ACS of ASHRAE 55 and MS 2680:2017. The primary results revealed that 62% of the hourly indooroperative temperatureof the case study house waswithin 80 to 90 % of the acceptability limit. The optimal comfort hourly indooroperative temperaturewasbetween25.5 to 29.5 °C with a prevailing mean outdoor air temperaturebetween23 to 30 °C, which represents 90% of the acceptability limitrange. Moreover, the results also complied with the standards of ACS, where the average hourly indooroperative temperature was less than 31 °C,with a prevailing mean outdoor air temperatureless than32 °C, which wasan acceptable indoor state for occupants' comfort. The findingscompliedwith RMK 12 Theme 3, which aims to be a carbon-neutral country by practising sustainable architecture and construction. The design of naturally ventilated houses, such as Negeri Sembilan Malay houses in hot-humid climates, can be a model reference for modern housing design development.

The Malaysian government is prioritizing the development of affordable housing units to cater to the needs of the underprivileged. However, it is not sufficient to merely meet the required number of units; it is crucial for developers to understand the actual demand for affordable housing in urban areas. This is because even middle-class homebuyershave their own preferences when it comes to purchasing a home at an affordable price. Therefore, this study aims to investigate the current demand attributes that contribute to the affordable housing demand model in urban areas, using Wangsa Maju, Kuala Lumpur, Malaysia asa case study. Data was collected from 400 potential buyers of affordable housing units, and 25 significant attributes of housing demand were examined. Partial Least Square Equation Modelling (PLS-SEM) was used to develop the housing demand model. The findings revealed that a total of five factors with nine attributes in housing demand significantly contribute to the affordable housing demand model in urban areas, as determined by the coefficient’sdetermination, path coefficient, effect size, and predictive relevance towards endogenous variables of housing demand.Overall, the result has confirmed that government intervention has play major role in supporting affordable housing development and at the same time has encourage the potential buyer form the right group to have their own house at affordable price.

Applying Value Stream Mapping (VSM) in the mining industry can increase productivity in production process activities. The coal mining industry has a vital role in life and is an essential investment in the regional economy. However, since 2017, coal production has experienced instability based on data from the Central Bureau of Statistics for East Kalimantan Province (2021) and has yet to meet consumer demand. Previous studies have only shed light on the critical theory that VSM has extended to many industries. However, those studies need to explain the concept of applying VSM to the mining industry. Therefore, to support this theory,a case study from the mining industry was conducted to determine cycle times and identify value-adding and non-value-adding activities. A current state map is developed after making the necessary observations and calculations. Different improvement proposals are identified, and a future state map for the industry is constructed. As a result, a 23.4% reduction in cycle time and 56.1% reduction in lead time ensure its applicability in the mining industry to increase productivity and meet customer demands. VSM is a powerful tool that helps mining managers and operators identify waste and opportunities for improvement. Efficiency is one of the most important things to consider in this industry. This study is especially true in the coal mining sector.

Rapid urbanization in Malaysia has led to an increasing crime rate, necessitating an understanding of the relationships between crime, the environment, and community. This study examines the causal connections among fear of crime, sense of community, and Crime Prevention Through Environmental Design (CPTED) using a quantitative approach with 171 respondents in Selangor and Putrajaya. Previous research has highlighted the psychological effects of crime and the efficacy of defensible space and CPTED in reducing crime in residential areas. However, the causal relationship between sense of community and CPTED requires further investigation. The study's causal model confirms that fear of crime does significantly influence CPTED implementation and the sense of community. Additionally, a strong sense of community significantly impacts CPTED, underscoring the role of community engagement in enhancing crime prevention strategies. These findings have practical implications for policymakers and urban planners, emphasizing the importance of addressing fear of crime to create safer environments that foster community cohesion. Strategies may include improved lighting, surveillance systems, and community-building initiatives. Further research can explore underlying mechanisms and moderating factors. Ultimately, addressing fear of crime, sense of community, and implementing CPTED can enhance community well-being and promote a sense of security.

Nowadays, plastic pollution is one of the most critical issues related to sustainability development that need to be solved. Studies indicated that addition of certain amount of recycled plastic from Polyethylene Terephthalate (PET) in asphalt mixture has improved the engineering properties such as marshall stability, moisture resistance, rutting and fatigue resistance. However,the main challenge of direct incorporation of recycled plastic in binder is the thermal incompatibility of two phases which are glass transition and melting temperature.Previous research findings indicated that reduction in particles diameter to micro scale would decrease the PET melting point. Hence, this study investigates the potential of micronized PET from recycled plastic bottle as filler in asphalt pavement. Micronization process at laboratory was carried out to determine the appropriate method prior incorporating it into asphalt mixture. The micronized size of PET incorporated at 0%, 4%, 8%, and 12% by weight of filler is then evaluated for its volumetric properties,mechanical, and adhesion properties. The results showed that the volumetric properties of the asphalt were affected by the presence of micronized PET. The mechanical properties in terms of Resilient Modulus and Indirect Tensile Strength showed increment with addition of micronized PET. Similar trend also observed on adhesion properties. Hence, the findings indicated the potential of utilizing the recycled MPET for local road construction.

This paper presents a study on the Factors Influencing the Adoption of Artificial Intelligence (AI) in Crisis Management. The research identifies 28 AI usage factors categorized into seven groups: Large-Scale Machine Learning, Deep Learning, Reinforcement Learning, Robotics, Computer Vision, Natural Language Processing, and Internet of Things. The study conducted a questionnaire survey among 281 employees at the UAE National Crisis and Emergency Management Authority, using purposive sampling to assess theiropinions regarding the impact of these usage factors on the adoption of AI in crisis management. The collected data underwent descriptive analysis to determine the ranking of AI usage factors within each of the seven groups. In terms of group rankings, Robotic emerged as the top-ranking factor, followed by Reinforcement Learning. Large-Scale Machine Learning occupied the next position, succeeded by Natural Language Processing, Deep Learning, Internet of Things, and Computer Vision, which held the lowest rank. Furthermore, when examining the correlation between these usage factor groups, it was discovered that most of them exhibited strong positive correlations, with correlation coefficients ranging from 0.634 to 0.934. This indicates that changes in one variable are associated with predictable changes in another variable. While this information can be instrumental in understanding relationships and making predictions, it does not establish a causal relationship.

Authors:   Universiti Tun Hussein Onn Malaysia, Latif Irfan Alias Farhan , Mohd Nor Mohd Khir ,   Universiti Tun Hussein Onn Malaysia
Published: January 2024

Aluminum demand is projected to increase in the future. To help meet the demand, recycling aluminum has been employed for quite some time. Conventional recycling of aluminum leads to CO2 and greenhouse gas emissions. Therefore, direct recycling techniques such as hot press forging are being used and researched to provide an alternate recycling route that leads to even lower emissions, material losses, and energy consumption. The recycled aluminum 6061 alloy obtained from hot press forging is relatively new. Hence, not much is known about its capabilities and properties, including its impact penetration behavior. In this study, recycled 6061 aluminum alloy plates of 5 mm obtained through hot press forging are used in high-velocity impact tests using a single-stage gas gun to test the material’s penetration behavior. Two tests are carried out at velocities ranging from 141 to 308 m/s, all resulting in full penetration. The material was observed to have decent energy absorption capabilities, ranging from 70% to 81%. The penetration behavior, however erratic, shows signs of both ductile and brittle failure modes.

The quality of teaching and learning across all TVET disciplines can be enhanced by promoting technology-inclusive TVET. Using the Technological Pedagogical and Content Knowledge (TPACK) model, this study examines the interrelationships between the knowledge required by art teachers to effectively integrate technology in teaching at the TVET level. The study assumed that quality TVET practices could be achieved if TVET teachers had a solid understanding of their subject matter, pedagogical procedures and knowledge about employing technological tools. This research used a quantitative data approach and adopted a Structural Equation Modelling (SEM) analysis technique to measure the path coefficients of direct or indirect influence between exogenous and endogenous variables. A quantitative survey instrument based on the TPACK model was adopted to collect data from 152 art teachers sampled across various public educational institutions in Ghana. Data analysis was performed with SPSS and SmartPLS using an online data collection procedure. The study demonstrates a significant relationship between art teachers’ knowledge and how much technology can be integrated with TVET. The following mechanisms were revealed: the mastery of technological tools, technologically driven instructional approaches, and a teacher's technical knowledge and abilities as the fundamental mechanisms required to foster efficient skill development at the TVET level. This implies that educators, training institutions, policymakers, and stakeholders in the TVET ecosystem should pay special attention to these mechanisms to strengthen the teaching and learning delivery of TVET.

The post-pandemic has affected all educational institutions, including TVET. The situation has shifted fully online learning into a blended one, conducted online through e-learning and onsite through face-to-face learning. In this learning, students must do self-directed learning before coming to the class, known as the flipped classroom method. On the other hand, to trigger their effort to do so, applying the case method is valuable to improve their problem-solving skill. Therefore, the flipped classroom and case method integration needs to be implemented. In the flipped classroom method, students must use CAI media to optimise the learning outcome. This study aims to see the effectiveness of integrating CAI into case method-flipped classrooms in improving the problem-solving skills and learning outcomes of TVET students. This study used a quasi-experiment with a pre-test and post-test control group design. The research instruments were a questionnaire and an achievement test with 62 participants. Based on the results, it was found that there was a significant difference in students’ problem-solving skills and learning outcomes between control and experimental groups. Research findings showed substantial improvements in students’ material understanding and problem-solving skills. Students reported high engagement and satisfaction with the proposed interactive learning model. Thus, it can be concluded that the CAI-integrated Case Method-Flipped Classroom effectively improves TVET students’ problem-solving skills and learning outcomes. The novelty of this research is that it offers an innovation from various learning models in TVET that TVET educators can implement. The model provides time efficiency availability of such a lead-in that bridges the initial material to the primary material. Hence, the investigation results in this study provide a new knowledge reference for the TVET education curriculum.

Thailand's industrial sector has made significant progress in adopting and implementing technology associated with Industry 4.0. As technology advances and industries become more digitally driven, a skilled and adaptable workforce becomes paramount. The responsibility for cultivating such human resources lies with educational institutions. They are the foundation for developing a workforce that can thrive in the digital age by staying responsive to industry trends, fostering business collaboration, and prioritising technical and soft skills. Work-integrated learning (WIL) is one of the educational programs that can help improve student skills by integrating the theoretical exploration of a particular subject with its practical implementation within a professional environment. The WIL program enables individuals to demonstrate competence, expertise, and the capacity to keep up with contemporary technologies. This paper proposes the new WIL model for the WIL program in the industrial engineering profession, known as the CWILE model. The study aims to identify and establish the benefits of the CWILE model. These benefits include enhanced skill development, improved readiness for industry demands, and a seamless transition from education to the workforce. The initial step in the research procedure involved collecting stakeholders' perspectives on the existing WIL program in the industrial engineering department of the engineering faculty at Rajamangala University of Technology Lanna (RMUTL), Thailand. Following stakeholder feedback, the CWILE model was developed and implemented with the participation of eighteen students in the WIL program. The effectiveness of the CWILE model was assessed through a comprehensive evaluation of student competencies: core competency, functional competency, and professional competency. The evaluations were conducted at three distinct intervals: before, during, and after instruction. This longitudinal assessment allows a nuanced understanding of how the WIL program influences student competencies. The results of this study show that the duration of attending the WIL program is positively correlated with an increase in all competencies.

Glocalization: Lessons Learned from Globalization
Authors: Unger Stephan
Published: January 2024

The process of creating independent international entities in order to preserve the international liberal order is facing increased backlash as deteriorating confidence in democratic structures emerges. One problem is that these institutions supposedly accumulate more and more power over time in order to maintain and develop their function. This poses a substantial threat to liberalism as confidence and trust in democracy eases. This paper highlights the most important failures of globalization and weighs in the concept of glocalization as a possibility to increase wealth through competition enhancement and to contain the threat of emerging socialism across the globe.

У кавітаційній порожнині протікають реакції трансформування радикалів за участю хімічно активних газів, в результаті цього після колапсу кавітаційної бульбашки в розчин переходять продукти радикального розкладання молекул, що призводить до накопичення у воді молекулярного кисню, перекису водню та інших сполук. Одночасно відбувається зміна структури води з утворенням вільних водневих зв’язків, що зумовлює її підвищену активність та реакційну спроможність. У водних системах активація полягає у зміні ступеня рівномірності розподілу домішок за об´ємом системи, агрегації та диспергації, а також зміні їх активного стану. Сфера застосування результатів. Описаний у статті метод дозволить інтенсифікувати проведення технологічних процесів у порівнянні з класичним способом перемішування за допомогою звичайних перемішуючих пристроїв. Висока швидкість протікання реакцій свідчить про те, що реакції відбуваються у зоні cхлопування бульбашки. Це є позитивним технологічним моментом.

Published: January 2024

The dependence of the resistivity on the final coking temperature was studied on cokes obtained from the charge of one of the leading coke plants in Ukraine in a laboratory furnace designed by SE "UKHIN" with electric heating. The increase in the final temperature naturally contributes to an increase in coke readiness and the degree of orderliness of its structure. This is manifested in an increase in coke strength (increased resistance to grinding forces and post-reaction strength, reduced abrasion), increased coke density and porosity, reduced reactivity, volatile substance yield and specific electrical resistance. The increase in the final temperature contributes to the deepening of thermochemical polycondensation processes of coke formation, which causes the loss of additional low-molecular weight products, resulting in a slight decrease in the yield of gross coke and its sulphur content with a simultaneous increase in ash content. The previously theoretically substantiated hypothesis about the exponential nature of the dependence of the decrease in the specific electric coke with an increase in the final coking temperature was experimentally confirmed. Processing of the obtained experimental data made it possible to determine the numerical characteristics of this dependence, which makes it possible to determine the rational level of final coking temperatures when producing coke for various applications. In particular, to produce coke with a resistivity not exceeding 0.1 ohm∙cm, the final coking temperature should not be less than 957 oC. This is in line with the practice of coke production. To produce blast furnace coke with a lower resistivity, a higher temperature is required, while to produce ferroalloy coke with a higher resistivity, on the contrary, a lower temperature level is sufficient. Keywords: coal coke, electrical resistivity, final coking temperature, coke readiness, blast furnace coke, ferroalloy coke. Corresponding author I.V. Shulga, e-mail: ko@ukhin.org.ua
Solutions for the reconstruction of coke sorting aspiration systems.
Authors: Trembach T.F. , Klymenkо A.G.
Published: January 2024

The paper summarizes the information on the operation of existing coke sorting aspiration systems at coke plants. It is shown that, according to the data of instrumental measurements carried out at operating coke plants, the actual emissions of dispersed particles from the exhaust pipes of coke sorting plants require the development of measures to reduce the emissions of suspended solids into the atmosphere. At the same time, almost all coke plants at coke sorting plants with wet coke quenching have aspiration systems with one-stage cleaning in wet dust collectors, which is justified by the relatively low initial dust content of the aspiration air. At the same time, at coke sorting plants, after dry coke quenching, the dust content of the aspiration air is much higher and reaches 10 g/m3. Given the high dust content, aspiration systems at such enterprises provide for a two-stage purification - in dry cyclones of the first stage of purification and in wet dust collectors of the second stage. Conclusions are drawn on the efficiency of coke dust collection processes in various dust collectors, and a justification for the use of dry methods of aspiration air purification in coke sorting systems is provided. A new concept of an aspiration system with a dry dust collection method is presented and recommendations for the modernization of existing systems are developed. The basic technical requirements for the use of dry cleaning of aspiration air of coke sorting plants in bag and pocket filters (for sieving and transporting wet quenching coke) are presented. Recommendations for reducing the possible relative humidity of aspiration air in coke sorting systems (during sieving and transporting wet quenching coke) have been developed. The design features of aspiration units with a dry method of aspiration air purification for wet coke quenching paths are presented. Keywords: coke production, coke dispersal facilities, coke sorting plant, aspiration system, dust removal unit, pollutant emissions. Corresponding author: T.F. Trembach, e-mail: ozos@giprokoks.com

Accurate yield estimation before harvest is important for farmers and researchers to optimize field management and increase productivity. The purpose of this study is to develop efficient cotton plant productivity using field studies and satellite imagery. Nitrogen (N) fertilizer is an important nutrient in plant development, and when suboptimal amounts are applied, it can cause yield reductions. Different vegetation indices were employed to analyze the dynamics and yield of cotton plants, with a primary focus on the Red, Near-Infrared (NIR), and Red Edge bands derived from satellite imagery. The objective was to assess the nitrogen content in the plants. The present study involved a comparative analysis of various vegetation indicators in relation to cotton plant production. The productivity of the cotton plant was assessed by employing the indices that exhibited the most influence. The analysis revealed that the MCARI index exhibited the worst weaknesses, while the CLRE index demonstrated the main performance. The productivity of each index was computed, and it was observed that the CLRE index exhibited the closest proximity to the average productivity of 34.48 cents per hectare (cent/ha). Similar results have been observed in other indices. The MCARI index exhibits a distinct value of 32.08 in comparison to the others indices. The results of this study illustrate the potential of satellite imaging in monitoring cotton yield, hence offering valuable theoretical and technological assistance for estimating cotton production in agricultural areas.

What impact does the COVID-19 pandemic era have on the incidence of myocardial infarction-related fatalities in distinct age groups of male and female? A comparison study (2017–2022)
Authors: Kumar Dr Piyush , Anupama
Published: January 2024

Abstract: Several studies, conducted earlier during the SARS, MERS, and recent COVID-19 pandemic, have indicated that coronavirus infection, particularly COVID-19 can lead to cardiac damage. There have been recorded cases of myocarditis or cardiomyopathy linked to COVID-19 vaccines, specifically those that use mRNA technology such as BNT162b2 and mRNA-1273, primarily affecting males between the ages of 16 and 30. The prevalence and characteristics of sudden death due to myocardial infarction in various age groups of both males and females during the COVID-19 period have not been extensively examined as compared to the time before COVID-19. The aim of this study is to analyse and contrast the disparities in the average and proportion of abrupt fatalities associated with heart attacks (MI) in different age groups of males and females in the COVID-19 era and the time prior to the global outbreak. This study revealed that the maximum number of sudden deaths due to MI occurs at age 45 and above but below 60 years. The percent increase in mean sudden death due to MI in the Covid-19 period compared to the pre- COVID-19 period mean was highest in females (68.57%) of age groups 14 and above but below 18 years, while it was lowest in the males (9.51%) of the same age group. The lowest mean mortality, 38.5 (95% Conf. Interval-Mean-23.81 -53.19) due to MI during the study period was found in females in age groups 14 and above but below 18 years. The highest mean mortality was 9540.5 (95% Conf. Interval-Mean: 8551.93- 10529.07) due to MI during the study period observed in Male aged 45 and above but below 60 years. The overall percent increase in fatalities due to MI in 2022 compared to 2017 is greatest (88.46%) in females between 14 and 17 years, while the lowest is in females between 45 and 59 years (27.87%). In all age groups an increase in fatalities due to MI is seen in 2022 compared to 2017.
