A passive flow control on a generic car model was numerically studied. The Ahmed’smodel with rear slant angle of 25° was used to study the aerodynamic effects. The concave deflector was tested for the first time in this paper to minimize the drag coefficient. The deflector was fixed between the end of the roof and the top of the rear window. Simulations were firstly performed for different straight deflector’s length rates based on the length of the model, for Reynolds number Re=7.89×105 and inlet velocity Uo=40m/s. A significant drag reduction was observed for the high length rate studied. Secondly, the length rate was fixed, and the deflector was investigated for different curvature radius and inclination angles. It was concluded that the Ahmed model with concave deflector gives the best drag reduction, compared to the model with straight deflector and the model without deflector. It was observed that the installation of a concave deflector on the Ahmed model widen the wake zone and remove the vortices from the rear base. For this case, the lift coefficient was reduced, this improves the stability of vehicle on the road at high speed.

The globe is beginning to face fast-expanding global warming concerns that require immediate treatment. Biodiesel can be considered the most widely used and versatile sustainable fuel for a variety of uses. Because it is biodegradable, environmentally friendly, and renewable, it offers a viable solution to the looming energy crisis. Waste cooking oil is among the locally available sources that might be utilized as an extra source in different countries at a reasonable cost. Combining used cooking oil and diesel is a viable option for diesel engines because it has been certified for use at blending ratios as low as 20% as a commercial fuel. However, when it comes to fuel additives, the best alternative is to use waste cooking oil at high mixing ratios with diesel to power diesel engines. The goal of this research is to examine the various performance parameters of a diesel engine and the characteristics of biodiesel blended fuels by measuring the specific fuel consumption of the brakes and the thermal efficiency of the brakes and to investigate the impact of isobutane and ethanol additions at rates of 5% and 10% on the properties of the fuel and engine efficiency to enhance the specifications of the blended fuel in high proportions B40. Mixed fuel B40 with 10% ethanol (B40E10) can be used as a highly mixed fuel to enhance diesel engine performance. The density, kinematic viscosity, and flash point of diesel fuel were the lowest and rise with the amount of WCOB in the mixture, while the blended fuel B40 had the greatest value and improved with the percentage of additives. Increases in the proportion of additives also result in a visible rise in the braking force and fuel consumption.

Authors:   Széchenyi István University, Al Hudaib Hayder Thabit , P. Ray Richard ,   Széchenyi István University
Published: January 2024

The idea of multi-hazard interactions and risk assessment, particularly in relation to both natural hazards and hazards triggered by anthropogenic processes, has been widely used, especially in recent decades. Numerous areas worldwide, as well as various sectors, face exposure to multiple hazards. These hazards encompass natural phenomena like floods, earthquakes, hurricanes, and more. In comparison, the human-induced or anthropogenic processes associated with infrastructure development, along with other potential human activities such as, land and cover use change, contribute to the overall hazard landscape. Both natural hazards and anthropogenic-induced directly led to infrastructure collapse and loss of functionality with other consequences for human lives, economy, beside the environment impacts. Limited studies have been conducted on the implementation of the comprehensive multi-hazard interaction approach, which is globally or regionally required, along with detailed studies on the interaction between different multi-hazard sources and their interrelationships in short-term or long-term scenarios. The current research aims to review previous literature and studies on the multi-hazard interaction approach, methodologies of visualization and classification, as well as explores the potential of multi-hazard associated with road networks, infrastructures, and dams. The research utilizes simulation various models and tools such as, Geographic Information System (GIS) beside Remote Sensing (Rs) techniques. The current study concludes that using multi-hazard maps, hazard matrix, and fragility curves represents highly valuable and very useful and flexible tools for implementing and visualization hot spot areas exposure by multi-hazard consequences and vulnerability analysis for short and long-term scenarios. In addition, the current review highlighted for development a holistic conceptual framework for multi-hazard and risk assessment associated with hydraulic structures such as dams, road networks and infrastructures with hazard exposure analysis to be used as tools for a decision support system (DSS) in order to develop urban resilience, risk management and hazard mitigations.

Typically, monitoring the volcanic activity of a volcano is carried out using volcanic seismic methods. However, this method is technically less flexible. Volcano seismic data is not freely available. Access to these data centers must be authorized by the data authority. Therefore, it is necessary to use other methods as an alternative. The alternative method used in this study is remote sensing using the Landsat 8 satellite sensors. Landsat 8 satellite imagery data can be freely accessed and easily downloaded. Landsat 8 image analysis is implemented with Google Earth Engine (GEE). GEE is a remote sensing image analysis programming tool with a cloud computing platform. The GEE programming implementation is open source. With GEE, the evolution of Arjuno-Welirang volcanic activity can be monitored accurately. The use of GEE with a cloud computing platform also makes it easier to process large remote sensing data because the downloaded file's size is unlimited. GEE has successfully conducted an LST analysis on Landsat 8 satellite imagery of the Arjuno-Welirang complex area in the 2016-2021 range. The LST calculation is performed by adding the surface emissivity correction obtained based on the NDVI value. According to the results of the LST calculations that have been obtained, the surface temperature in the Arjuna Welirang Crater area experienced the highest increase in 2018, reaching 33.94 oC, with a larger contour size of thermal distribution image than the others. This increase in thermal based volcanic activity is in accordance with the increase in seismic activity monitored by the VSI (Volcanological Survey of Indonesia).

One of the major conflictscontinuously occurring in Malaysia is the issue of race and religious relationships. Today, houses of worship in Malaysia have always been seen as isolated entities that can add to race relations and nation-building conflicts. This issue has led to the planning of houses of worship as nation-building elements in forging social inclusion among the different religious buildings of other faiths. Therefore, this research aims to evaluate mosques' social inclusion characteristics, which can contribute to the more extensiveframing of Malaysian planning policy on the sustainable designof houses of worship. Toreflect the ideal of SDG 11, Sustainable cities and communities and SDG 16, Peace, justice and strong institutions, it is essential to identify social inclusivity as one of theprimarydesign approachesforany Islamicinstitutionsand mosques designs. Should the mosques be part of the nation-building entities and notjust community centres for each faith? This research covers selected case studies mainly inKuala Lumpur, representing the city with the most educated and diverse multi-faith context. Four significant mosques were selected and studied through observationsand interviews data collection approach. The research findings indicate that elements such as scale, massing, permeability, visibility, territoriality, and iconic imagery are essential to design criteria for mosques. Significantly, this research provides suggestionsand guidelines for designers and committee leaders of all religions in Malaysia to re-look at the activities and planning aspects of their houses of worship. Furthermore, it helps to promoteinclusive elements such as social interaction, tolerance, and understanding of different religious beliefs.

Published: January 2024

This study starts from the diagnosis that a new educational research methodology is essential in overcoming the deep-rooted conflicts in educational research, so as to flexibly cope with the rapidly changing times and respond to the ever-developing academic trends. Not only new phenomena that cannot be understood nor explained with the current existing frameworks but also transboundary and convergent events that demolish the modern dichotomous boundaries are frequently occupying the schools of this age. There is an urgent need for the introduction of even more detailed and diverse methodologies in order to capture these complex realities. This study will examine the various disciplinary possibilities of Latour’s ANT for overcoming the problems educational research has come to face and, in particular, will explore the possibilities of ANT’s educational research methodology. The expectations for this new ANT methodology include the improvement of educational practices by means of describing the educational reality that is coherent to the complex and transboundary educational phenomena and, consequently, its expected contribution to the new trends in academic progress.

Authors:   Korean Educational Research Association, Jang Eunah , Chung Hyewon
Published: January 2024

This study was conducted to explore the key predictors of change in sense of community during adolescence, to classify latent classes of sense of community changes, and to test the impact of key predictors on classification of latent classes. To this end, SEMforest was applied to KELS 2013 data from 3rd to 8th wave to derive the key predictors of changes in sense of community during middle school and high school, and discontinuous piecewise latent class growth analysis was utilized using a three-step approach. The results were as follows. First, as a result of SEMforest, five student-related variables were found to be common to both the middle and high school years, and two student-related variables were selected differentially for each of the middle and high school years. Additionally, one parental-related variable was derived to be common to both middle and high school years, and two parental-related variables were selected discriminatively for each of the middle and high school years. Second, three latent classes in sense of community during adolescence were identified: low-level decline (22.2%), middle-level gain-decline (52.0%), and high-level gain-decline (25.8%). Third, self-concept (academic and social), rule observance, multicultural acceptance (relationship with multicultural neighbors/friends), and volunteerism awareness were found to have a significant effect on classifying latent classes in both the middle and high school years. Finally, based on the main results, educational implications for fostering a sense of community among adolescents were discussed.

Authors:   Korean Educational Research Association, Kim BuKyung , Li Lian Mei , Park Jisu , Song Tae Min
Published: January 2024

General strain theory, routine activity theory, self-control theory, social learning theory, and social bond theory are representative theories to explain the causes of juvenile delinquency. However, as online delinquency emerges, it is necessary to verify whether the aforementioned theories can be adopted for both online and offline delinquency. To examine these theories, this study identified 76 empirical articles on South Korea adolescents that utilized one of these theories. Using meta-analysis, this study found that there was a statistically significant difference in the effect size among theories. The effect of social learning theory (ES: 0.29, p < .001) on delinquency was highest, followed by self-control theory (ES: -0.20 p < .001), routine activity theory (ES: -0.19, p < .001), general strain theory (ES: -0.17, p < .001), and social bond theory (ES: -0.16, p < .001). Furthermore, the moderation effect of online and offline delinquency on the theories was only statistically significant according to general strain theory. The effect size of offline delinquency was larger than the effect size of online delinquency. Findings of this study will be used to utilize more effective factors for future studies and interventions.
Reconceptualization of School Democracy through a New Materialist Lens: Focusing on the Expansion of Membership
Authors:   Korean Educational Research Association, Um Su Jung , Baek Byoung-Bu
Published: January 2024

This study aimed to explore what insights new materialism might provide for advancing the discussion on school democracy with a specific focus on the issue of extending membership to nonhuman beings. It reviews the literature that sought to move away from a minimalist approach to school democracy and confirms that schools could be a place for experimentation and imagination for a new democracy. Then, it discusses what it might mean to extend the membership of school democracy to nonhuman beings through a theoretical framework informed by new materialism as follows. First, extending the membership of school democracy to nonhuman beings requires an onto-epistemological turn. Second, it shifts democratic subjectivity from something fixed to something created “through” actions performed in a specific context. Last, it is critical to cultivate response-ability in order to practice school democracy based on this onto-epistemology. Based on these discussions, this study re-conceptualizes school democracy as a space-time in which all school members, including nonhuman beings, renew their subjectivity as a democratic citizen by attending and responding to each other with a sense of entanglemt.

Authors:   Korean Educational Research Association, Gwak Naram , Kim Yongnam
Published: January 2024

Instrumental variable (IV) analysis is a statistical approach that enables valid estimation of causal effects, even in non-experimental settings where randomization is not possible. Despite its potential utility, IV analysis remains underutilized in Korean education research. The purpose of this paper is to introduce the fundamental principles of IV analysis and its applications. Specifically, the paper employs causal graphs to provide a more intuitive explanation of the key assumptions and mechanism underlying IV analysis. In addition to providing theoretical explanations, the paper explores the applicability of IV analysis in the context of education research through examining randomized encouragement designs, perceived construct studies, and treatment noncompliance. By doing so, this paper aims to facilitate a better understanding of theoretical foundations and practical considerations when applying IV analysis in education research.

Authors:   Korean Educational Research Association, Jeong Seongkyeong , Park Hwanbo
Published: January 2024

This study aims to investigate the typology of multiple citizenship among Korean adolescents and the predictive factors in the global era. The study analyzed data from the 6th wave of the 2013 Korean Educational Longitudinal Study and utilized latent profile analysis to explore the typology of multiple citizenship. To identify the predictive factors determining multiple citizenship, an automated machine learning algorithm was used to find the most performant model. SHAP (Shapley additive explanations) techniques were then applied to provide interpretable explanations of the machine learning results. The key findings are as follows. First, in the latent profile analysis, the multiple citizenship of adolescents was categorized into “high multiple citizenship,” “moderate multiple citizenship,” and “low multiple citizenship.” Second, the results of automated machine learning showed that gradient boosting exhibited the highest performance among machine learning techniques. When predicting the key variables related to adolescents’ multiple citizenship through machine learning, it was found that communication competence emerged as the most important predictor, followed by cognitive information processing skills, awareness of cultural and artistic activities, independent career maturity, educational experiences involving cultural diversity and international issues, gender, and relationships with teachers and peers. Based on these results, this study provides policy recommendations and implications for effective civic education for adolescents.

Published: January 2024

This study investigated whether there were differences in the clusters of parental support perceived by middle school students and by their parents, and whether there were differences in the levels of academic achievement and career maturity based on these clusters. Data from the 4th year (2016, N = 6,677, 50.7% female) of the Korean Education Longitudinal Survey (KELS 2013) was used to identify clusters and examine the differences in academic achievement and career maturity among the clusters. Four clusters were identified from the student data: emotional-focused support (33%), low emotional support (22%), overall low support (30%), and overall high support (30%). For the parent data, four clusters were also identified: academic- and emotional-focused support (39%), leisure-focused support (19%), overall low support (24%), and overall high support (18%). These findings confirmed differences in the perceptions of parental support between children and their parents. In both the child and parent clusters, overall high support exhibited the highest levels of academic achievement and career maturity. Notably, among the child clusters, there was no significant difference in academic achievement between overall high support and emotional-focused support. This suggests that the emotional support provided by parents, such as encouragement and expectations, plays a positive role in academic achievement. Furthermore, it was observed that parental suppor tin any form (e.g., leisure activities) had a more positive effect than low levels of support.

Rendahnya minat baca tersebut dipengaruhi oleh berbagai factor intern dan factor ekstern. Salah satu factor intern adalah belum munculnya rasa butuh dan rasa lapar akan membaca. Sedangkan factor ekstern yang mempengaruhi rendahnya minat baca adalah lingkungan sekolah yang kurang mendukung. Oleh karena itu, untuk menumbuhkan minat baca peserta didik adalah dengan menciptakan stimulus yang akan menumbuhkan minat baca peserta didik. Stimulus tersebut adalah dengan pengadaan pojok baca atau perpustakaan mini yang mudah dijangkau oleh peserta didik. Selain mudah dijangkau, pojok baca juga sangat fleksibel karena diletakkan di pojok kelas. Sehingga kegiatan membaca bisa dilakukan setiap saat entah dalam pengawasan pendidik ataupun secara mandiri. Dengan adanya pojok bac aini, diharapkan peserta didik dapat berbudaya literasi membaca sehingga pengetahuan yang dimiliki akan semakin luas.

Wilayah perbatasan Indonesia-Timor Leste seperti di kabupaten Timor Tengah Utara di kategorikan sebagai daerah terdepan, terpencil dan tertinggal sehingga memerlukan perhatian lebih besar dari pemerintah di semua sektor, termasuk pendidikan, Artikel ini bertujuan untuk melihat kesiapan guru dalam menghadapi perkembangan dunia pendidikan, khususnya dalam hal teknologi. Data diperoleh melalui penelitian dengan metode pengamatan dan wawancara. Hasil penelitian menunjukan bahwa pemahaman tentang digitalisasi pendidikan hanya terbatas pada penggunaan peralatan teknologi informasi dan komunikasi, bukan penggunaan berbagai platform pembelajaran berbasis teknologi dalam pembelajaran. Terdapat bantuan pemerintah untuk mengatasi digitalisasi pendidikan ini tetapi masih sangat terbatas. Faktor infrastuktur dan ekonomi menjadi hambatan. Selain itu, kurangnya motivasi dan kemauan guru untuk beralih ke pembelajaran berbasis teknologi menjadi faktor penting yang membuat bantuan pemerintah itu seperti tidak efektif. Bantuan infrastuktur teknologi harus bersamaan dengan mempersiapkan guru tidak hanya cara mengoperasikan peralatan teknologi tetapi penggunaan platform dan media pembelajaran berbasis teknologi
