Pedagogical translanguaging and trans-semiotizing in a LOTE Arabic classroom: the coordination of semiotic resources in alphabetic teaching and learning

ABSTRACT Purpose Based on the notion of translanguaging/trans-semiotizing, the study aims to explore an effective pedagogy in a foreign language classroom to respond to the multilingual and multimodal context and facilitate language teaching and learning. Specifically speaking, the study attempts to investigate the coordination of multiple semiotic resources during the teaching and learning of Arabic alphabet in a LOTE (Language other than English) Arabic classroom at a Chinese university. Design Drawing from a classroom ethnography for two academic years, the current study collected data from a focal Arabic teacher and learners via classroom recordings, semi-structured interviews, and stimulated recalls; multimodal conversational analysis and qualitative content analysis were used to analyze the data. Findings The findings illustrate how multilingual resources can be activated to organize the classroom, how multimodal resources can be coordinated to contribute to language learning, and how students’ individual resources can be integrated into the entire semiotic resources to enhance their understanding of Arabic orthography. Value The implications for LOTE education and teacher training programs are presented, including the encouragement of a multilingual, multimodal and multisensory teaching approach in the LOTE classroom. LOTE teacher's agentive role is demonstrated; LOTE learners are expected to make positive response to the teacher’s pedagogy, and become active co-constructors of the language classroom and agents of translanguaging/trans-semiotizing practices.

Older Adults’ Perceptions, Experiences, and Preferences of a Gamified Cognitive Training Program

With cognitive plasticity being a “sluggish” process, regular long-term engagement in interventions like cognitive training is required to realize the potential that such interventions may confer for cognitive enhancement. A significant challenge associated with extended cognitive training studies is poor adherence and attrition. The current qualitative investigation therefore explored 66 older adult participants’ experiences of, and motivations during, a gamified cognitive training program to understand reasons for (non)adherence. Preferences regarding cognitive training were also explored to provide insight into how such programs might be designed and implemented to maximize motivation and long-term engagement. Using a qualitative description design drawing upon thematic analysis, findings revealed that participants were generally motivated by challenge, novelty, and opportunity to focus. In contrast, repetition, external factors, and negative mindsets detracted from the motivation of participants. Suggestions to improve cognitive training programs to promote long-term engagement included the addition of a large selection of games, an incentive system, mini daily challenges, reminder notifications, and social features. These findings may inform the design of cognitive training programs that accommodate the preferences and needs of older adults, which in turn, may promote adherence and improve intervention effectiveness.

Application of BIM and Virtual Reality of System Integration Design and Development in Medical Building Projects: A Case Study in China

Design outcomes in the Medical Building Projects (MBPs) must satisfy the demand of the medical staff and stakeholders. However, they often do not have the relevant engineering expertise, so the design team is prone to misunderstandings when communicating with them using traditional two-dimensional (2D) Computer-Aided Design (CAD) drawings. The medical staff may not readily visualize and understand the design and then provide feedback to the designer through professional medical requirements or advice, which results in the need to redesign and carry out additional work during the design phase, thus delaying the progress of the MBPs. To address these challenges, this study aims to develop an integrated system based on BIM, advanced rendering engines, and VR technology for use in non-immersive and immersive VR environments. Moreover, in this study, the integrated system was applied to the infection-building project of the People's Hospital of Qingbaijiang District, Chengdu City, and semi-structured interviews were distributed to 16 engineers, designers, contractors, and medical staff who had been involved in the whole project to validate the practicality and effectiveness of the integrated system. The results indicate that this system integration is an efficient visual communication and simulation tool in medical design. Key advantages include enhanced communication efficiency between the design team and medical stakeholders, improved visual interaction, and streamlined decision-making processes within a 3D VR/BIM environment. The successful implementation of this integrated system is expected to significantly aid design teams and stakeholders in effectively managing medical design tasks in future projects.

ПОДХОД К ВЕКТОРИЗАЦИИ ЧЕРТЕЖЕЙ КОНСТРУКТОРСКОЙ ДОКУМЕНТАЦИИ НА БУМАЖНОМ НОСИТЕЛЕ

The work proposes a solution to the problem of vectorization and machine interpretation of drawings of design documentation on paper, which provides the ability to automate the transfer of images of products, parts and assembly units into CAD systems. A number of neural network architectures have been proposed for detecting and recognizing the main elements of a drawing (frame, title block, specification, views, projections and sections), inscriptions, dimension and extension lines, as well as primitives that directly describe the product. For hierarchical and interconnected vectorization, a mechanism for semantic segmentation of drawings based on a graph neural network is proposed. The results of the implementation of the main stages of solving the problem of vectorization of design drawings are presented.

Serviceability fragility assessment of non-seismically designed railway viaducts in Turkey under near-field and far-field earthquakes

While many railway viaducts still in use in Turkish railway networks are located on active fault zones that produced historical destructive earthquakes, they are not seismically designed in accordance to current standards. This study aims to provide a better understanding about the serviceability fragility of such systems by conducting detailed probability-based seismic assessments under near-field and far-field earthquakes. To achieve this, firstly, 3D finite element models of a range of selected viaducts in Turkey were generated based on their original design drawings. The developed FE models were validated by comparing the analytical modal frequencies with the results of in-situ dynamic tests involving a series of acceleration measurements. Nonlinear time history analyses were then carried out under 25 near-field and 25 far-field real three-component ground motion recordings to obtain the seismic response of each selected viaduct. Subsequently, probabilistic seismic demand models were defined using linear regression analysis to determine relationships between engineering demand parameters (EDPs) and ground motion intensity measures (IMs). Peak ground acceleration (PGA), peak ground velocity (PGV) and spectral acceleration at 1.0 s (Sa (1.0)) were used as the IM parameter, while the maximum lateral displacement of the bridge spans for different service velocities defined in the Eurocode was considered as the EDP at serviceability damage state. Finally, analytical fragility curves for all the selected railway viaducts were developed considering maximum damage probability for the IM levels. The results, in general, demonstrate the seismic vulnerability of the existing viaducts in Turkey. It is shown that while at low speed limits the viaducts exposed to far-field ground motions were more vulnerable than those under near-field ground motions, at high speed limits the viaducts subjected to near-field ground motions were more vulnerable. Also, it is seen that reinforced concrete and masonry viaducts are generally more vulnerable to earthquakes than the steel viaducts. The outcomes of this study should prove useful for the seismic risk assessment, loss estimation and rehabilitation of the railway transportation networks in future studies.

Follow-up visits after pediatric concussion and the factors associated with early follow-up: a population-based study in British Columbia.

To explore the rates and timing of a first follow-up visit for children and adolescents with a concussive injury and to identify factors associated with follow-up timing. A descriptive, correlational design drawing on linked, population-based administrative data of concussed children and adolescents (ages 5-18 years) from the province of British Columbia (BC), Canada. Data were accessed through Population Data BC. Descriptive statistics and binary logistic regression were used to analyze the data. From January 1, 2016 to December 31, 2017, we retrieved 22,601 cases of concussion, of which 19% had an early follow-up visit (N = 4,294), 4.9% had later follow-up (N = 1,107), and 76.1% had no follow-up (N = 17,200). The factors of older age, living in a rural area, higher socioeconomic status, and seeing a specialist physician at an initial concussion diagnosis were more likely to have an early follow-up visit. Early follow-up is important for recovery, but most children and adolescents with a concussion do not receive follow-up in BC.

Human resource management practices and employee retention: Job satisfaction as a mediator in Malaysia’s information technology (IT) industry

This study investigates the impact of human resource management (HRM) practices on employee retention and job satisfaction within Malaysia’s IT industry. The research centered on middle-management executives from the top 10 IT companies in the Greater Klang Valley and Penang. Using a self-administered questionnaire, the study gathered data on demographic characteristics, HRM practices, and employee retention, with the questionnaire design drawing from established literature and validated measuring scales. The study employed the PLS 4.0 method for analyzing structural relationships and tested various hypotheses regarding HRM practices and employee retention. Key findings revealed that work-life balance did not significantly impact employee retention. Conversely, job security positively influenced employee retention. Notably, rewards, recognition, and training and development were found to be insignificant in predicting employee retention. Additionally, the study explored the mediating role of job satisfaction but found it did not mediate the relationship between work-life balance and employee retention nor between job security and employee retention. The research highlighted that HRM practices have diverse effects on employee retention in Malaysia’s IT sector. Acknowledging limitations like sample size and research design, the study suggests the need for further research to deepen understanding in this area.

Research on Categorizing and Deriving Proportions of Hanoks for Planning and Designing Hanok Architecture

A Hanok is a representative wooden structure in Korea and is recognized for its environmentally friendly architecture. Since the 2010s, the demand for Hanoks has increased significantly, but new Hanoks tend to be built with only numerical changes to existing plans or only imitate the shape. This is due to the fact that architectural designers do not have systematic training in Hanoks, so they rely on carpenters with extensive experience in Hanok construction. As designers reconfigure Hanok’s floor plan space using existing drawings to accommodate modernization, the building’s form changes as spatial reduction and expansion occur. This change in form creates problems with the proportions of the elements that make up a Hanok, such as the roof being smaller than the body or the building being taller than the scale of the floor plan. A more significant issue is the lack of recognition of the proportion problem. Therefore, this study has a direct role in the systematic design and construction of Hanoks by deriving objective proportions of Hanoks. To increase the objectivity of the data, numerical data of floor plans, cross-sections, and front elevations of national heritage Hanoks with well-preserved traditional shapes were extracted and analyzed for patterns. Subsequently, similar forms were categorized, and ultimately, the plan, section, and elevation proportions were quantified. The results indicated that the plan was characterized by spatial expansion in the X-axis direction more than the Y-axis while maintaining rectangular proportions. The cross-sectional structure showed a change in height depending on the width of the plan, and it was found that the larger the width of the plan, the lower the height ratio of the cross-section. Of particular interest was the analysis of the ratio of exposed area in the elevation, divided into three areas: roof, Gongpo, and the frame, and the interaction between the roof and Gongpo was confirmed within 63.7% of the total exposed area ratio. This result suggests that the proportion of Hanoks exists despite the different scales, times, and locations of Hanoks. This study can serve as a reference for designers in the process of verifying and modifying design drawings, and it is significant in providing a method and direction for building a new dataset for Hanok design.

Design of a welding table as a medium for determining elbow points and joints

Welding is a method of joining two or more metals with electrode extension media using current heating and voltage according to the variation in the thickness of the iron material used. Welding is one of the connection media with a patent system, meaning that the results of the process can be changed by damaging the results of the welding process. From looking at several welding workshops, almost all of them to do welding are under or on the ground so many workers complain that they tend to be more tired and the welding results are less than optimal, especially for symmetrical or straightness of the connection results. The method used in this research is to design a welding table that is adjusted to the level of needs, especially for the height of the table and the centric axis to combine so that the results of the connection process are completely straight and reduce the results of welding defects. The purpose of designing this welding table is to use it as a method for working on the welding process so that the welding results are really strong and straight according to the design drawing. From the results of the design process, a welding table is obtained with iron material as a table base to place the workpiece to be cut. using borders of iron with a thickness of approximately 120 x 240 x 40cm using Material: Iron plate about 5-6 mm thick. In addition, the results of the design process also reduce the welding process time for blunt joints from 85 seconds to 48 seconds, overlap joints from 85 seconds to 60 seconds, and T joints from 88 seconds to 81 seconds. The quality of the welding results is visually better, the results of welding defects are smaller and straighter or symmetrical

Fostering ecosystem understanding: The synergistic impact of inquiry-based instruction and information literacy

In the field of environmental education, it is crucial to obtain a profound understanding of students' learning about ecosystem concepts, particularly with regard to the intricate processes of material cycling. Material cycling involves the movement and transformation of elements and compounds within ecosystems and serves as a cornerstone for effective instructional techniques aimed at improving learning outcomes. This study examines the synergistic potential of merging inquiry-based instruction with information literacy within the context of the “mini ecosystem” theme to increase seventh-grade students' comprehension of ecosystem concepts, material cycling, modeling design, and visual literacy. Utilizing a quasiexperimental design, the student cohort was divided into an experimental group that was exposed to inquiry-based instruction and information literacy and a control group that utilized integrated audiovisual media. Assessment tools included standardized tests, open-ended inquiries, design drawings, and evaluations of visual literacy.This study sheds light on students' comprehension of concepts related to ecosystems and material cycling and highlights the effectiveness of integrating inquiry-based instruction and information literacy. Notably, the experimental group surpassed the control group in several aspects, including understanding and higher-order thinking of ecosystem concepts, overall model design with material selection, and overall visual literacy, including aesthetic techniques and creative imagination. However, no significant differences were found in conceptual design or material cycling of model design or in theme composition in visual literacy. In both groups, students with higher pretest scores did not exhibit improvement in the understanding of ecosystem concepts. Despite the identified limitations, the results underscore the potential benefits of each individual component (i.e., inquiry-based instruction and information literacy) as well as their combined synergistic effect in bolstering students' grasp of ecosystem concepts. The study concludes by discussing its limitations and providing suggestions for future research.

Business model innovations amidst adverse economic conditions: the role of CEO values

Purpose The current business environment is characterized by high levels of uncertainty that affect the global economic system and have the greatest impact on small and medium-sized enterprises (SMEs). With an elevated degree of perceived uncertainty, Chief executive officers' (CEOs) of SMEs find themselves in a situation where the old approaches to decision-making are irrelevant and the time to create new ones is limited. The purpose of this study is to examine whether appealing to personal values helps CEOs cope with a high level of perceived uncertainty and make decisions about the further development of the firm by undertaking business model innovations (BMI). Design/methodology/approach This study follows a multiple case study research design drawing on data collected from 10 Russian SMEs. Findings The authors show that CEOs’ communion values lead to innovations in the revenue model and value architecture dimensions of the business model. CEOs who are inclined to agentic values introduce innovations in the revenue model and value offering dimensions. Those executives who balance between the two types of values tend to also balance between different types of innovations in the elements of the business model. Originality/value The results indicate that personal values of CEOs play an important role in managerial processes and the strategic choice of a BMI type. Moreover, personal temporal focus orientation serves as a translation mechanism in the relationship between CEO values and BMI in SME settings.

Development and Testing of Small-Scale Flash Dryer for Maize Bran

Sun drying is the most common technique used to dry various food products due to its economic convenience. However, it is not effective owing to its unreliable nature leading to microbial deterioration and aflatoxin contamination of food. In Tanzania, about 1.3 million tonnes of maize bran are at risk of deterioration annually due to improper drying. The aim of this study was to design, fabricate and test an efficient small-scale flash dryer for maize bran. Using principles of material and energy balance, a small-scale flash dryer with a throughput of 500 kg of dry product per hour was designed resulting in a nominal diameter of 387 mm and a drying length of 20 m. Design calculations and drawings were done using MS Excel 2021 and SolidWorks 2018 respectively. Empirical procedures were used to fabricate and test the dryer. The material of construction used in the flash duct was food grade (stainless steel, SS 201). A fuel blend of Waste Engine Oil (WEO) and diesel (85%-15%) was used with a novel heavy oil burner. It was observed that at an inlet air temperature of 150 °C and air velocity of 12 m/s, moist maize bran was dried from 37% to 10% w.b. The fabricated flash dryer's energy efficiency, specific energy consumption, and specific energy utilization are 74%, 3.4 MJ/kg water evaporated, and 1.71 MJ/kg dry maize bran respectively. It was concluded that the fabricated small-scale flash dryer displayed improved energy performance compared to others presented in literature. Better instrumentation was recommended for feedback control on burner operation and process monitoring which further enhances the performance of the fabricated small-scale flash dryer.

Optimized data representation and understanding method for the intelligent design of shear wall structures

The generative intelligent design of building structures has been a rapidly evolving field in recent years, with shear wall structures efficiently designed using generative adversarial networks (GANs). Nevertheless, using RGB images to represent structural design drawings may not accurately capture the correlations and distinctions between building components, leading to shear-wall structure design inaccuracies. To address these challenges, this study proposes an optimized data representation and understanding method for the intelligent design of shear wall structures. Specifically, a component-based feature space data representation method was introduced to achieve a more accurate description of drawing features. A feature mask was also employed to precisely locate the key target areas for generating shear walls, enhancing the model's understanding of the data features. Additionally, a GAN with global and local discriminators was established to enhance the neural network's ability to generate shear wall designs at both the global image and local component levels. Finally, a training method for a GAN with dual discriminators based on feature masks is proposed. Experimental analyses and case studies showed that, compared with existing widely used GAN-based designs, the structural designs generated by the GAN trained with the proposed data representation and understanding methods demonstrated superior consistency with engineer-designed structures and outperformed structural seismic resistance.

3D printing of beams with the possibility of transverse reinforcement, considering the peculiarities of the construction printer

3D printing of load-bearing structuresis creating rapid changes in the construction industry. New opportunities for building complex architectural forms are emerging, and the speed and quality of work is accelerating. But don't forget about the production specifics of this latest technology. An important detail that many people forget about is that 3D printing with concrete or mortar requires the use of some kind of reinforcement, and there are still nostandards for solving this issue. This is ensured by the use of construction 3D printers, which allow for complex operations both at industrial factories and directly at the construction site. However, despite all the advantages of this technology, there are also a number of challenges due to insufficient optimisation of new systems. The required stiffness of the structures is not achieved due to the absence of a spatial reinforcement structure, which should be provided by vertical reinforcement ties (transverse reinforcement). The article presents a solution to the problem of transverse reinforcement in 3D printing of load-bearing beams, proposed and performed by the authors. To implement the task, design drawings of test beam structures were developed. The article presents the design of the beams and the sequence of their production by 3D printing. The beams were manufactured, according to the sequence of work developed by the authors of the article, by the Ukrainian company 3D TECHNOLOGY UTU LLC. The work resulted in the development of a technology for manufacturing beams with the possibility of reinforcingthem with a vertical welded cage in the design position. To determine the physical and mechanical characteristics of the materials, samples of cubes andprisms, as well as reinforcement, were made. The proposed technology of printing beams using a construction 3D printer made it possible to producestructures that meet the previously developed design and technological solutions and made it possible toplace transverse frames in the design position, which allows the structure to take not only bending moments but also transverse forces.

HVAC Design Optimization for Pharmaceutical Facilities with BIM and CFD

Building Information Modeling (BIM) has been widely used in the past decade to enhance the design quality of Heating, Ventilation, and Air Conditioning (HVAC) systems. However, in specialized areas such as pharmaceutical facilities, HVAC design has traditionally relied on Computer-Aided Design (CAD) drawings. This conventional approach does not allow for the simulation of temperature distribution or the verification of system efficiency, which may lead to design failures. To address these challenges in pharmaceutical facilities, this study proposed a BIM-based approach for optimizing HVAC design with Computational Fluid Dynamics (CFD). By employing CFD to simulate the dynamic airflow conditions of pharmaceutical clean rooms, the effectiveness of HVAC systems can be verified. A case study of a clean room HVAC design is presented to demonstrate the workflow. The results of the case study indicated that the pharmaceutical temperature requirements were met within 1 °C during the design optimization simulation, and there was a 95% match in the 72 h temperature mapping test during site validation. The results confirmed that using CFD with BIM not only successfully simulates the design intentions of indoor air quality but also suggests HVAC system optimization for the required clean room design. The findings of this paper contribute to the body of knowledge on overcoming the limitations of the traditional CAD-based HVAC design process and provide valuable insights on optimizing HVAC design with BIM and CFD technologies.

A pilot model representing a university building, including the surrounding streetscape, was constructed using the Unreal Engine. By using available CAD design drawings and GIS technologies, the physical spaces were modelled. The physical and analytical environments were integrated into the digital twin; material flow analysis was also conducted. The developed framework aims to offer a detailed visualization of building behaviour, facilitating comparisons with urban metabolism analysis. This approach holds promise for sustainable urban design by integrating diverse data streams through digital twin technologies. The potential impact of this research extends to the tracking, mapping, and analysis of crucial resource flows, such as materials, water, energy, and waste, fostering circular economy strategies within the built environment. Understanding urban metabolism facilitates the identification of resource-efficient opportunities, promoting resource recovery and reuse to reduce the environmental impact of urban cores. Embracing digital twin technologies and urban metabolism analysis offers cities streamlined data collection processes, supporting standardization and sustainable urban practices. This study marks a critical step towards integrating diverse data streams into urban metabolism analysis, aligning with circularity objectives in the built environment. By adopting this framework, cities can better understand new production and consumption patterns that prioritize the responsible use of natural resources, contributing to a more sustainable and resilient future.
