The Implementation of Art Appreciation Courses in Chinese University General Education: A Case Study

This research critically evaluates and assesses the current status of Art Appreciation Courses (AAC) within the General Education (GE) curriculum in Chinese universities. The investigation is focused on delineating the strengths, pinpointing the weaknesses, and identifying potential areas for improvement. The research methodology encompasses a thorough review of relevant literature and the implementation of a qualitative case study approach. Interviews were conducted with four AAC instructors, selected through purposive sampling, and their documents were subjected to analysis. The primary findings suggest that the instructors are committed to enhancing students' humanities knowledge, aesthetic education, and artistic abilities by developing appreciation skills. However, they encounter several challenges, including a limited knowledge base among students, inadequate course duration, insufficient facilities, and a tenuous connection between the course and the major. The instructors adhere to a teaching philosophy integrating aesthetic education using a situational model, cultivating positive attitudes and distinctive courses. Our study recommends several enhancements for Art Appreciation Courses (AAC) in Chinese universities. We suggest diversifying AAC topics and facilitating cross-cultural comparisons. Active learning should be promoted through interactive methods and participation in art activities. Interdisciplinary integration can be bolstered by collaborating with other disciplines. Lastly, resources should be augmented, and assessments should be diversified to foster creativity, and student engagement should be enhanced.

Numerical evaluation of internal femur osteosynthesis based on a biomechanical model of the loading in the proximal equine hindlimb

SummaryFemoral fractures are often considered lethal for adult horses because femur osteosynthesis is still a surgical challenge. For equine femur osteosynthesis, primary stability is essential, but the detailed physiological forces occurring in the hindlimb are largely unknown. The objective of this study was to create a numerical testing environment to evaluate equine femur osteosynthesis based on physiological conditions. The study was designed as a finite element analysis (FEA) of the femur using a musculoskeletal model of the loading situation in stance. Relevant forces were determined in the musculoskeletal model via optimization. The treatment of four different fracture types with an intramedullary nail was investigated in FEA with loading conditions derived from the model. The analyzed diaphyseal fracture types were a transverse (TR) fracture, two oblique fractures in different orientations (OB-ML: medial-lateral and OB-AP: anterior-posterior) and a ”gap” fracture (GAP) without contact between the fragments. For the native femur, the most relevant areas of increased stress were located distally to the femoral head and proximally to the caudal side of the condyles. For all fracture types, the highest stresses in the implant material were present in the fracture-adjacent screws. Maximum compressive (-348 MPa) and tensile stress (197 MPa) were found for the GAP fracture, but material strength was not exceeded. The mathematical model was able to predict a load distribution in the femur of the standing horse and was used to assess the performance of internal fixation devices via FEA. The analyzed intramedullary nail and screws showed sufficient stability for all fracture types.

Integrating gamification and gaming technologies into Ukrainian education: transforming the learning experience

Changes in the field of education in Ukraine are necessary for integration into the European space. The personality of the learner, pedagogy of partnership, and the constant need to motivate and engage students drive teachers to search for modern forms of work. Gaming technologies can be effective tools for stress relief, adapting to specific situations, and fostering relationships within a collective. The aim of this research is to examine and analyse the impact of gamification and gaming technologies on the educational process in Ukraine. This study employs both theoretical and empirical methods. The theoretical methods include analysis, synthesis, and generalization, while the empirical methods use comparison and description. The study analyses different scientific perspectives on gaming technologies and gamification in Ukrainian education, paying special attention to the implementation of relevant gaming forms of cooperation with students during the period of changes in Ukrainian education, particularly in the educational process. Research has shown that gamification and gaming can have a positive impact on the development of a learner's personality, motivation for learning, relationships within the student community, academic performance, and acquisition of necessary knowledge and skills for future development and career. The research results highlight the usefulness of incorporating gaming technologies in the educational process, particularly in the context of the digitization of Ukrainian education. The study shows the effectiveness of group cooperation, quests, quick quizzes, situation modelling, business games, and other teaching methods. The article provides evidence of qualitative improvements in the educational process within the Ukrainian education system. These changes are primarily driven by the need to cultivate a new type of personality that can develop essential skills and competencies for the future during their secondary education. Gaming technologies and gamification play a significant role in transforming learning by attracting learners' attention and motivating them to complete tasks.

Persinggungan Kepemimpinan Transformational Dengan Kepemimpinan Visioner Dan Situasional

The purpose of writing this article is to determine the intersection of transformational leadership with visionary and situational leadership. This research uses a type of library research. Library research is research carried out by reviewing various journals and related reference books. The results of his research show that the transformative leadership model is a leadership model that can be an alternative to be applied in the current organizational system with various organizational dynamics and changes in line with the increasingly high demands of society. This is in line with the need for leaders who are able to bring about change. Transformative leadership is a leadership model that is different from traditional leadership models which view the relationship between leaders and employees (leadership and followership) as based solely on reward and punishment. A visionary leader is also understood as a leader who has a clear vision and mission in the organization. He has the ability to predict future events and express them in a clear and measurable vision and mission. Visionary leaders are able to raise the enthusiasm of their members with their motivation and imagination, to make the organization more alive and growing. Another situational leadership model is known as the Situational Contingency leadership model which revises the behavioral approach which is considered unable to explain ideal leadership. This approach illustrates that the style developed depends on the leader himself, the support of his followers, and a conducive situation. By analyzing the basic motivations of their subordinates, leaders can place them in appropriate situations. Transformative, visionary and situational leadership models have several elements in common, both in terms of systems, processes and objectives of Islamic Education Management. From the system side, there are elements of education unit leaders, educators, education staff, and various other elements; It is hoped that they can synergize in a process that is conducive to achieving goals.

Tire–road contact modelling for multibody simulations with regularised road and enhanced UA tire models

AbstractMultibody simulations play an important role in the study of the dynamic behaviour of road vehicles, being one of the key aspects the modelling of the tire-road interaction. The tire-road contact modelling is required to detect the contact between the tire and road and to obtain the tire contact forces from the tire-road relative motion. The first part of the problem is solved by a contact detection algorithm, whereas the second part is handled by a tire model. In both cases, the trade-off between accuracy and computational cost needs to be addressed in the road dynamics scenario. For the contact detection problem, this work proposes a methodology in which the road is described by a mesh of triangles while the tire is described by a toroid. The triangular mesh road input can be directly extracted from any CAD model. To avoid the geometric discontinuities due to the transition between triangular patches, a set of auxiliary points is used to obtain a continuous variation of the road surface normal, based on the method proposed by Rill (Multibody Syst. Dyn. 45:131–153, 2019. In the process of contact detection, all kinematic quantities required by the tire-road contact model are evaluated. The tire–road forces are evaluated using the enhanced UA tire model, which is a numerically stable and efficient development of the original tire model proposed by Gim and Nikravesh (Int. J. Veh. Des. 12, 1991; Int. J. Veh. Des. 12:19–39, 1991; Int. J. Veh. Des. 12:217–228, 1991). Both the contact and tire models have smooth transitions between their internal transitions, thereby reducing the need for the variable-step ODE integrators to unnecessarily decrease time steps. The advances on contact detection and the tire–road contact models, proposed here, are demonstrated with a set of road vehicle simulation scenarios in which the influence of various modelling parameters on the stability and efficiency of the simulations is addressed. The novelties of the work consist not only in the demonstration of the enhanced UA tire model in practical situations but also in the description of the new tire–road contact methodology that employs a simple description of the road geometry, to achieve smooth tire–road contact forces.

Document language moderates the text-belief consistency effect

ABSTRACT When researching socioscientific topics, particularly on the Internet, readers face multiple texts that they must integrate into a coherent mental model. Previous research in monolingual settings has found that comprehension is biased toward readers’ prior beliefs (text-belief consistency effect). Considering that the Internet is multilingual, this experiment focused on the influence of document language on the text-belief consistency effect. Assuming differences in epistemic prestige among languages, we hypothesized that document language would act as a credibility cue and moderate the text-belief consistency effect. Seventy-four German university students read two conflicting texts either in their L2 English (higher epistemic prestige) or in their L1 German (lower epistemic prestige). Participants constructed stronger situation models for the belief-consistent text than for the belief-inconsistent text only when they read the texts in German. These results indicate that document language can act as a source characteristic that may reduce belief biases in comprehension.

Interactive Learning: Unpacking the Influence of Computer Simulations on Students’ Mathematical Modeling Processes

Mathematical modeling and use of technology have been recognized as powerful vehicles for advancing mathematical thinking. The use of technology to aid students to gain understanding about real-world mathematical problems has long been a subject of inquiry. Using the extended Blum’s modeling cycle as the theoretical framework, this study explores how computer simulations influence fifth-grade students’ mathematical modeling processes. We investigated interpretations and perceptions of students regarding a situation model, and how these interpretations and perceptions changed as a result of exposure to the simulation. Observing students as they worked with three interactive computer simulations during task-based interviews, we found that animated graphics of the simulations helped the participants to visualize the problem and learn about the effect of different variables and their interactions on the outcomes of the simulations. Students explored simulation environments, ran simulations to observe outcomes of specific settings, and formed conjectures to describe the effect of simulation variables on the outcomes. Analyzing participants’ activities and movements along the extended Blum modeling cycle, we propose a three-stage learning model composed of “exploration and discovery”, “structured inquiry”, and “synthesizing”.

Analysis of the WeWork Bankruptcy Case

This paper use case analysis and strategy analysis methods for the bankruptcy of Softbank for more than $13 billion US dollars in 2018, and in 2022 to analyze the acquisition process of WeWork acquisition, the impact of WeWork bankruptcy, and Softbank's countermeasures. The analysis of this paper shows that the business pre-bankruptcy status and key factors are the key to the WeWork bankruptcy, and the post-bankruptcy impact also needs to consider the association with the acquisition. Finally, the measures taken by WeWork for the company's bankruptcy restructuring were discussed, as well as the challenges and opportunities faced by Softbank after WeWork's bankruptcy. On the one hand, the slowdown in global economic growth and increased uncertainty have brought enormous pressure to Softbank. On the other hand, with the continuous advancement of technological innovation, Softbank Group can achieve sustained growth by investing in emerging industries. This paper provides theoretical and practical references for theoretical research and practice in related fields. This paper reminds investors to understand the company's financial situation and business model during the domestic acquisition process. Attention should also be paid to the risk management after the acquisition.

Prediction of small-scale leak flow rate in LOCA situations using bidirectional GRU

It is difficult to detect a small-scale leakage in a nuclear power plant (NPP) quickly and take appropriate action. Delaying these procedures can have adverse effects on NPPs. In this paper, we propose leak flow rate prediction using the bidirectional gated recurrent unit (Bi-GRU) method to detect leakage quickly and accurately in small-scale leakage situations because large-scale leak rates are known to be predicted accurately. The data were acquired by simulating small loss-of-coolant accidents (LOCA) or small-scale leakage situations using the modular accident analysis program (MAAP) code. In addition, to improve prediction performance, data were collected by distinguishing the break sizes in more detail. In addition, the prediction accuracy was improved by performing both LOCA diagnosis and leak flow rate prediction in small LOCA situations. The prediction model developed using the Bi-GRU showed a superior prediction performance compared with other artificial intelligence methods. Accordingly, the accurate and effective prediction model for small-scale leakage situations proposed herein is expected to support operators in decision-making and taking actions.

Advancing 3D Dental Implant Finite Element Analysis: Incorporating Biomimetic Trabecular Bone with Varied Pore Sizes in Voronoi Lattices.

The human mandible's cancellous bone, which is characterized by its unique porosity and directional sensitivity to external forces, is crucial for sustaining biting stress. Traditional computer- aided design (CAD) models fail to fully represent the bone's anisotropic structure and thus depend on simple isotropic assumptions. For our research, we use the latest versions of nTOP 4.17.3 and Creo Parametric 8.0 software to make biomimetic Voronoi lattice models that accurately reflect the complex geometry and mechanical properties of trabecular bone. The porosity of human cancellous bone is accurately modeled in this work using biomimetic Voronoi lattice models. The porosities range from 70% to 95%, which can be achieved by changing the pore sizes to 1.0 mm, 1.5 mm, 2.0 mm, and 2.5 mm. Finite element analysis (FEA) was used to examine the displacements, stresses, and strains acting on dental implants with a buttress thread, abutment, retaining screw, and biting load surface. The results show that the Voronoi model accurately depicts the complex anatomy of the trabecular bone in the human jaw, compared to standard solid block models. The ideal pore size for biomimetic Voronoi lattice trabecular bone models is 2 mm, taking in to account both the von Mises stress distribution over the dental implant, screw retention, cortical bone, cancellous bone, and micromotions. This pore size displayed balanced performance by successfully matching natural bone's mechanical characteristics. Advanced FEA improves the biomechanical understanding of how bones and implants interact by creating more accurate models of biological problems and dynamic loading situations. This makes biomechanical engineering better.

What Happened to Simulation-Based Education in Outpatient Setting in The 21st Century: A Scoping Review.

Simulation-based education (SBE) is an instructional approach that aims to accurately recreate real-life scenarios and engage learners in the practical application of lesson content. By replicating critical elements of clinical situations, SBE facilitates a deeper understanding and better preparation for managing such conditions in actual clinical practice. SBE offers promising prospects for improving medical education and patient care in various settings, such as outpatient clinics. Therefore, this scoping review aims to determine to what extent the most effective components and standards of the simulation have been considered in outpatient education. The present scoping review adheres to the guidelines outlined in the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist" and the "Joanna Briggs Institute (JBI) Reviewers' Manual". This review focused on articles that specifically focused on the use of simulation in outpatient education. Google Scholar, PubMed, Scopus, Embase, and ERIC were searched for keywords related to simulation, ambulatory care, outpatient clinics, and medical education from January 1, 2001, to August 12, 2023. The search indicated 513 articles, which were narrowed down by title and abstract relatedness. Twenty-nine articles entered the study's second phase, and after reviewing their full text, nine articles that explicitly reported simulation use in outpatient education remained. Based on the findings of eligible articles, the ten most frequent components of SBE that should be considered and followed discussed. These features were training facilitators, pre-briefing sessions, the type of simulation techniques, the site of simulation participation, the simulation duration, unit of participation, extent of direct participation, Simulation fidelity, feedback, and debriefing and reflection. SBE is a contemporary method of practical training for medical students that involves realistic modeling or simulation of clinical situations. It enhances learning effectiveness and provides a safe, educational atmosphere for teaching and learning. Designing simulations adhering to established standards and carefully considering essential components improves efficiency and effectiveness.

IMPROVING THE EFFICIENCY OF TRAFFIC LIGHT CONTROL AT ROAD INTERSECTIONS

From the functional point of view, the intersection is the most complex element of the road network. It is here that the traffic flows in different directions cross, and various maneuvers take place. This indicates that the intersection is a place with an increased concentration of conflict situations and an increased risk of traffic accidents. At most high-flow intersections, traffic is controlled by traffic lights, and their inefficient operation can lead to unnecessarily long wait times and overall increase in traffic delays. The research analyzed a regulated intersection at the crossing of Stepana Bandery and Viacheslava Chornovola main streets in the city of Rivne. This intersection is characterized by constant significant traffic jams. To simulate traffic conditions at this intersection, the research used PTV Vissim software. Observations of traffic flows, their distribution by directions, and traffic light regulation parameters were used as initial data for modeling the intersection traffic scheme. The main problem that must be solved when considering isolated traffic light intersections is the calculation and optimization of the signal plan, which involves: determining the number of phases; determining cycle duration; distribution, i.e. determining parts of available green time for each phase; modeling of traffic situations that may arise due to the passage of priority vehicles, congestion of vehicles in intersection areas during peak periods or other situations. At the same time, it is necessary to achieve the best possible characteristics of the intersection functioning. According to the research results, the road conditions were modeled and the signal plan was optimized with the use of PTV Vissim software. Simulation modeling of the intersection included drawing a road network, installing traffic lights (signal controllers) with a description of their work (choosing the type of light signaling devices, creating signal groups and traffic light signals, parameters for coordinating signals), forming pedestrian zones and a node, performing calculations with subsequent analysis of the received data. In order to improve the efficiency of the intersection, two options for the operation of the traffic light controllers are offered: 1. Lengthening of the “green” phase, for the convenience of turning to the left (by reducing the phase of oncoming traffic in one direction by 5 seconds). The total duration of the cycle of 70 seconds will not change; 2. Implementation of the third phase – fully pedestrian in all directions, lasting 20 seconds. The total duration of the cycle will increase to 90 seconds. A more progressive measure can be the introduction of adaptive systems, which are based on new traffic monitoring technologies and allow obtaining accurate data on traffic flows in real time and performing adaptive control of traffic lights, that is, adapting the signal plan in real time to changes in traffic flows.

Pedagogical potential of competence tasks as a means of developing critical thinking of future economists

Purpose. The purpose of the article is to present the means of training future economists for analytical professional activity, which contributes to the development of critical thinking of specialists in economic specialties. Results. The article is devoted to one of the urgent problems of training future bachelors in economics: developing critical thinking in the professional training of economists. We prove that competency-based tasks of economic content are an essential means of developing the critical thinking of future economics specialists. The main competence tasks with economic content include problems with labor productivity, cost, elasticity, rent, interest, compound interest, profitability, market equilibrium, profit, income taxes, credit, optimal decision-making, etc. The competence tasks bind economic concepts with their quantitative and qualitative characteristics and connections. These tasks reflect real economic situations, and solving them contributes to the familiarisation of students with economic concepts and cause-and-effect relationships between them (at the level of representation, assimilation, or consolidation), mathematical models in the economy, development of skills to build and research mathematical models of economic situations, apply mathematical methods and regularities in specific production processes. Scientific novelty. The theory and practice of training economists, which uses competence tasks of economic content as a leading means of developing their critical thinking, has gained further development. The results of the survey of teachers and students confirmed the feasibility of the proposed approach to the use of competence tasks with economic content for the development of critical thinking of future economists. Practical value. Solving competence tasks contributes to developing students’ critical thinking, as it illustrates the process of applying knowledge, skills, and abilities to solving any problems that arise in practice (formalisation, solving a problem within a built model, interpretation). It is advisable to offer such tasks in studying specialised economic disciplines and the first courses in studying “Higher Mathematics”.
