Exploring Engineering Philosophy from an Epistemological Perspective
Authors:   The Korean Association of Practical Arts Education, Lee Choon-Sig
Published: June 2024

This study explores engineering philosophy from an epistemological perspective, aiming to improve students' critical thinking skills, foster interdisciplinary understanding, promote ethical reflection, and deepen engagement with the philosophical foundations of technology. The study uses a comparative analysis and critical review of the literature on the philosophy of engineering.
The results are as follows: First, the essence of engineering knowledge lies in practical application, problem-solving orientation, and interdisciplinary integration. Second, epistemological methods in engineering emphasize the importance of balancing intuition and analysis, critical thinking, rigorous experimental design, and verification and validation processes.
Third, while experience and expertise are certainly crucial in shaping engineering knowledge, it is necessary to critically examine the potential biases and limitations inherent in this process. Fourth, the epistemological challenges of interdisciplinary engineering necessitate humility, open-mindedness, and interdisciplinary integration. Finally, the ethical and social dimensions of engineering knowledge are essential considerations for responsible and sustainable engineering practices. Integrating ethical reflection into decision-making and embracing social responsibility and community involvement can enable engineers to contribute to social advancement while upholding professional integrity and ethical standards.
Future research suggestions include conducting a meta-epistemological analysis to study the fundamental assumptions, methodologies, and conceptual frameworks employed in engineering philosophy research from an epistemological perspective. It can explore the intersection of epistemology, ethics, and social theory in engineering practice and education. Finally, conducting historical and comparative studies of engineering epistemology in diverse cultural, historical, and technological contexts can offer meaningful insights.

Authors:   The Korean Association of Practical Arts Education, Park Yeonhwa , Kwack Hyeran
Published: June 2024

This study aimed to gather essential data for integrating horticultural therapy activities into the Wee class counseling program. The findings revealed that a substantial proportion (40.9%) reported substantial experience implementing horticultural therapy in the Wee classes, with 37.5% of sessions led by horticultural therapists. Horticultural therapy was widely perceived as beneficial for counseling (33.1%). The key prerequisites for introducing horticultural therapy into Wee classes were training for horticultural therapy counselors (59.1%) and budget support (27.3%). The anticipated benefits included diversifying counseling techniques (26.5%), applicability to diverse clients (25.3%), promoting counselor self-healing (12.6%), and emotional purification (33.9%). Target groups were individuals with emotional issues such as anxiety and depression (30.7%), interpersonal relationship problems (17.8%), behavioral problems like violence (13.5%), and addiction issues (11.5%). Counselor training (59.1%) was the foremost prerequisite for implementing horticultural therapy due to its educational effectiveness (34.6%), applicability in group counseling (29.8%), and potential to help counselors with burnout (19.1%). As for the composition of the horticultural treatment training program, 'the composition of the actual program that can be actually applied to horticultural treatment' was the highest (32.5%), and the most preferred operating session was 5 to 8 sessions (47.8%). The intention to participate in the horticultural treatment therapy sessions was reported to be high after the training (90.9%).
The necessity of horticultural therapy programs, based on the characteristics of Wee class counselors, was analyzed using t-tests for quantitative variables and chi-square tests (𝒙2) for qualitative variables with multiple categories. A significant correlation was found between counseling experience and the degree of training participation (p=.002), although the need for training was not significantly correlated with experience. Furthermore, there was a significant correlation between the operational experience of horticultural therapy programs and the degree of training participation (p=.012). Chi-square tests were employed to evaluate distribution variances among different groups based on their operational experience with horticultural therapy programs.

Authors:   The Korean Association of Practical Arts Education, Jeon Joong-won
Published: June 2024

This study analyzed content related to childhood development in six types of elementary school curriculum revised in 2015. The research question were: First, what are the characteristics of the external system and composition of the 2015 revised elementary school curriculum related to ‘childhood development’? Second, what are the characteristics of the contents of ‘childhood development’ in the 2015 revised elementary school curriculum?
The findings revealed that first, the contents on childhood development were organized within the first unit of the first semester of the 5th grade in the practical department of elementary school, planned for a duration equivalent to 3~4 sessions. Second, all practical arts textbooks outline development characteristics in body, cognition, emotion, and society, as well as individual differences in development and prerequisites for healthy development, based on related achievement standards. However, some textbooks omitted content on individual differences in development and the factors contributing to these differences.
Based on the results, the following suggestions for further research are made: First, more direct explanations of childhood development characteristics and the necessary conditions and methods for healthy growth and development should be provided. Second, more practical and specific activities that help students recognize individual differences in development beyond the individual should be presented. Third, it is crucial to discuss the factors that contribute to individual differences in development and explain that development outcomes can be influenced by individual efforts and acquired skills.

Published: June 2024

Over the past three years, the sales of sandals and rubber shoes have been significantly impacted by the global COVID-19 pandemic. This has coincided with the economic downturn, particularly in the industrial sector. One way to recover is through innovations in the sales of primary, secondary, and tertiary products. By providing high-quality services and prime performance from the human resources possessed, it is hoped that the company's performance can be improved. The purpose of this study is to understand the quality of service and sales performance. The method used in this study is a qualitative descriptive approach, where data collection was conducted through interviews, observations, and recordings. Through a literature review and the information obtained, it was found that the service provided by the salespeople being studied has an impact on their performance. The factors studied include product knowledge, clarity in presenting information, and the process of providing service quickly, accurately, and completely. Many studies on customer service quality have been conducted in service companies such as banks, hotels, and hospitals, but there have been few assessments of service quality in small industries with standardized service standards. The purpose of this study is to bridge this gap by evaluating the condition of service quality for customers to formulate effective and suitable strategies for improving the company. The limitations of this study are that it only focuses on one distributor company and additional approaches are needed to obtain more complex information.

Atmospheric precipitation in the West Pomeranian Voivodeship in Poland (1991–2020) – Annual and seasonal variability
Authors: Nidzgorska-Lencewicz Jadwiga , Mąkosza Agnieszka , Czarnecka Małgorzata
Published: June 2024

The paper presents a detailed analysis of precipitation conditions in the West Pomeranian Voivodeship in Poland, covering data from 21 poviats. The basic data consisted of monthly sums of atmospheric precipitation from 49 stations of the Institute of Meteorology and Water Management National Research Institute (Pol.: Instytut Meteorologii i Gospodarki Wodnej Państwowy Instytut Badawczy – IMGW-PIB) in 1991–2020. Variability of precipitation conditions was demonstrated through annual and seasonal totals, the share of seasonal precipitation in annual totals, and the ratios of summer to winter precipitation and autumn and spring precipitation. It was found that area averaged annual totals ranged from below 600 mm in the poviats located in the west of the Voivodeship to more than 800 mm in the poviats located in the north-east. On average, the lowest annual totals were recorded in the area of the Police (550 mm) and Gryfino (565 mm) poviats, and the average highest in the Koszalin (842 mm) poviat. In most poviats, there was a slight, statistically insignificant tendency of increasing annual totals. The contribution of precipitation in spring, summer, autumn, and winter to the annual total in the voivodeship was 21, 33, 24, and 22%, respectively. The greatest year-to-year variability was found for summer (Vs = 28–39%) and winter precipitation totals (Vs = 29–35%). The most statistically significant result of the analysed features was identified for the calendar spring. The most prominent statistically significant changes in precipitation conditions were observed in the Goleniów, Kamień, and Sławno poviats.

Authors: Belghemmaz Salah , Fenni Mohamed , Chomontowski Chrystian , Louadj Yacine , Afrasinei Mihaela G. , Degui Nouara
Published: June 2024

This study addresses date palm growth and Saharan agriculture’s substantial environmental changes in Ziban agroecosystems (ZAE). Arid climate and vulnerable soils make oasis environments fragile. Most soils are sandy and rich in saline accumulations. This study characterised ZAE dry soils, determined its typology using the World Reference Base for Soil Resources (WRB) classification and US soil taxonomy (ST), and assessed their degradation using remote sensing (RS). Fieldwork identified representative oasis based on gypsum, calcareous crusts, and salinity. Ten soil profiles were selected using two topo-sequences, and 27 samples were obtained at 0–30, 30–60, and 60–120 cm. Analyses were carried out on organic matter (OM), pH, electrical conductivity (diluted extract 1:5), CaCO3, gypsum, and soil texture. Oasis soils are dominated by gypsum and are all affected by salinity. The rates of OM and CaCO3 are low to moderate. The land use and degraded areas were identified using RS data, field research, and soil analytical results. Soil classification revealed variability in soil diversity. The Typic and Gypsic Haplosalids’ ST soil group (SG) and the WRB Reference Soil Group (RSG) of Gypsic Solonchaks (Hypersalic) and Yermic Gypsic Solonchaks are equivalent. The Typic Haplogypsids and Typic Petrogypsids (ST) correspond to the Gypsisols (WRB). The Typic Torripsamments (ST) are correlated with the Arenosls (WRB). Differentiating degraded areas according to their degree of degradation and specific soil features is made possible by characterising the soils and identifying their typology. Farmers must use the right management strategies for each situation to sustain the oasis agroecosystem.

First Report of Setaria equina Microfilariae Infection in an Adult Argentine Polo Pony Mare in Nigeria: A Case Report
Authors: Akinniyi Olumide O. , Vaughan Julie
Published: June 2024

Setaria equina is a common parasitic infection in horses that is transmitted by mosquitoes. The absence of previous reports regarding the presence of Setaria equina microfilariae in Nigerian horses highlights the need to confirm its existence in the region. Verifying the existence of this parasite would enhance our overall understanding of its global distribution, which could then inform the development of more effective control measures. This paper reports a case of Setaria equina microfilariae infection in an adult Argentine polo pony mare in Nigeria. The recently acquired adult Argentine polo pony mare was exhibiting depression and weight loss. Despite normal vital parameters, the horse had a poor body condition and no history of deworming. Laboratory analyses, including wet blood film examination, complete blood count, and serum biochemistry, revealed the presence of Setaria equina microfilariae and macrocytic hypochromic anaemia. Treatment involved a five-day course of intramuscular multivitamin injections and three weeks of subcutaneous ivermectin injections. Follow-up examinations demonstrated the absence of microfilaria and a return to an active and lively state. The case report details the clinical presentation, diagnostic process, and successful treatment of a recently acquired adult Argentine polo pony mare. A consistent deworming regimen is essential for horses, including those recently acquired, to prevent parasitic infections and enhance their overall well-being.
Foot and Mouth Disease in North Africa: Epidemiology and Control Strategies
Authors: Hemida Houari , Merdja Khaldia , Boumezrag Assia
Published: June 2024

Foot and mouth disease (FMD) is a highly contagious viral disease affecting livestock, caused by the Foot and Mouth Disease Virus (FMDV). The North African region is vulnerable to transboundary diseases, and the livestock population at risk is substantial. The genetic diversity of FMDV in the region poses challenges for control measures, as vaccination or recovery from one serotype does not guarantee protection against others. The risk of disease introduction through illegal animal movement is leading North African countries to follow strict WOAH sanitary measures and animal movement controls. Algeria has faced multiple outbreaks, some linked to the illegal movement of animals across borders. Tunisia experienced outbreaks in 2014 and 2017, with genomic analysis indicating connections to West African countries. Libya encountered historical FMDV incursions, and despite control efforts, illegal animal movement and inadequate facilities posed challenges. Morocco reported outbreaks in 1991 and later in 2015, introducing vaccination strategies. Egypt’s FMD history showed multiple serotypes causing outbreaks. Control strategies include vaccination, compensation for affected farmers, and control measures such as disease notification, surveillance, and movement restrictions. The compensation rates for farmers vary depending on factors such as animal type and the approved compensation approach. In conclusion, the complexity of FMD control in North Africa, highlights the need for regional collaboration, effective control measures, and ongoing vigilance to mitigate the economic and health impacts of the disease.

Authors: Dančová Nikola , Regecová Ivana , Gregová Gabriela , Király Ján , Szabóová Tatiana
Published: June 2024

Meat is an important food source, the nutritional composition of which, in conjunction with its desirable taste, positively affects human development and health. From a veterinary point of view, meat obtained from food-producing animals is also a potential reservoir for foodborne pathogens, including Escherichia coli. The prevalence and spread of antibiotic-resistant E. coli represent a threat to public health. For these reasons, the aim of this work was to identify the isolates obtained from food processing plants and to confirm the presence of E. coli species based on phenotypic and genotypic expression. The susceptibility of the investigated strains to antibiotics and their combinations was determined using the modified microdilution method. Dominant resistance was detected against ampilicin, tetracycline, cotrimoxazole, ampilicin + sulbactam, ciprofloxacin, and cefuroxime. Resistance to ertapenem, cefotaxime, tigecycline, and ceftazidime was also detected sporadically. Frequent mechanism responsible for resistance was generated an incomplete fluoroquinolone resistance induced by mutation and penicillinase with low enzyme expression. The occurrence of multidrug-resistant strains was also detected. Selected E. coli isolates were subjected to detection of genes encoding resistance to tetracyclines (tetA and tetB) and quinolones (qnrA, qnrB, and qnrS) by PCR. The tetA gene was confirmed in 68 % of the isolates, and the tetB gene in one isolate. The prevalence of the qnrA gene was found to be 29 % in the examined isolates. Two isolates showed the presence of the qnrS gene. The qnrB gene, as well as a combination of the qnrA and qnrB genes, was detected in one isolate.
Canine Babesiosis and Therapy Options – A Review
Authors: Malinovská Zuzana
Published: June 2024

Babesiosis is a disease caused by intraerythrocytic protozoal parasites, which occurs in animals and humans. In dogs, babesiosis can be caused by eight species of Babesia gene: i.e., B. canis, B. rossi, B. vogeli, B. coco, B. gibsoni, B. conradae, B., and B. negevi, which are bound to certain geographical areas. The disease has a focal nature and its transmission depends mainly on vectors, which are ticks of various species. Due to transstadial, and transovarial transmission, babesiosis is able to persist in natural foci in several generations of ticks, even without the presence of a susceptible host. Typical clinical signs associated with canine babesiosis are: fever, apathy, weakness, pale mucous membranes, icterus and hemoglobinuria. The disease can have an acute or peracute course, and subclinical and subacute infections have also been described. The clinical manifestations of babesiosis may vary depending on the particular species and strains, and their specific virulence, but also depending on factors that determine the host’s response to infection, such as age, individual immune status, and the presence of concurrent infections or other diseases. Medicines, from the group of antiprotozoans, a selected group of antibiotics, or their combinations are used for therapy. There are differences in the therapy of babesiosis depending on the Babesia species, the animal is often cured of the acute phase, but the parasite remains in the organism.
Development and empirical testing of a questionnaire-based algorithm to evaluate physical and psychosocial health status in performing artists / Entwicklung und empirische Testung eines fragebogenbasierten Algorithmus zur Erhebung des körperlichen und psychosozialen Gesundheitszustands darstellender Künstlerinnen und Künstler
Authors: Schemmann Heike , Zalpour Christoff , Ballenberger Nikolaus
Published: June 2024

Background

Health care providers like physiotherapists should address the needs of performing artists for a specific health care derived from physical and psychosocial (performance-related) complaints. The aims of this study were (1) to compose an algorithm including subjective outcome measures in order to suggest how to evaluate the physical and psychosocial health status of performing artists in its complexity in a manner as targeted and detailed as possible, and (2) to test the feasibility of applying this algorithm.

Methods

Questionnaires regarding different health dimensions were searched and assembled to an algorithm. The survey was applied to performing artists in order to test feasibility. The respective questionnaires were scored and interpreted in comparison to cut-off values.

Results

Performing-art-specific and body-region-specific standardized questionnaires in German with the highest possible psychometric quality were selected. The algorithm covers a series of questionnaires on health-related quality of life, complaints in physical matters—especially musculoskeletal and voice-specific—and in the psychosocial area. Based on specific predefined decision criteria the artist was guided individually through the survey. This was illustrated by the participants' flow through the survey. Profiles of physical and psychosocial complaints for subgroups of 103 participants were built based on multiple scores and showed problems in both dimensions.

Discussion

It is possible to illustrate the physical and psychosocial health status of performing artists in a multidimensional way using the novel algorithm. It could be used both for groups and individuals to build complaint profiles for research and clinical purposes.
The Institution of Prime Minister and Government in A Hybrid Regime in Ukraine (1996–2021)
Authors: Prokop Maryana
Published: June 2024

Hybrid regimes are characterised by a balancing act between democracy and authoritarianism, with neither political regime type being dominant. The balancing of the state between democratic and non-democratic modes of functioning can take the form of a state transforming from authoritarianism to democracy and a form of regression from democracy to authoritarianism, when the democratic system is upset by non-democratic mechanisms. The functioning of the political system in Ukraine during the years 1996–2004 was such that the authoritarian aspects of Ukraine’s hybrid regime overshadowed its democratic elements. Steven Levitsky and Lucan Way (2002; 2013) refer to this phenomenon as “competitive authoritarianism”. This term denotes regimes where authoritarian features are more prevalent than democratic ones, according to the concept. Since 2004, the Ukrainian political system has transitioned towards a hybrid regime that places more emphasis on democratic characteristics. In the following twenty years, the Ukrainian hybrid regime was transformed between democratic-authoritarian hybrid regime (as a result of the events of the “Orange Revolution”, and the “Revolution of Dignity”) and authoritarian-democratic hybrid regime (during presidency L. Kuchma and V. Yanukovych). The hybridity of the political regime also translated into the functioning of the chief state bodies. The aim of this study was to find an answer to the question whether and to what extent did the hybridity of Ukraine’s political regime imply on the specificity of the functioning of the institutions of the prime minister and government in the state. The research hypothesis is that the hybridity of the Ukrainian political regime, as a stage of transition from authoritarianism to democracy, partly contributed to changing the traditional order of functioning of the institutions of prime minister and government in the state just formally losing the head of state’s dominant role in the process of government functioning.

This case report describes the functional rehabilitation of a completely edentulous patient with complete dentures by a manufacturer-independent workflow with conventional clinical steps combined with computer-aided design, computer-aided manufacturing (CAD/CAM), and 3D printing technology. The result was 3D-printed complete dentures that were fully adapted, economical, and well-accepted by the patient.
Institutionalising the circular economy in regional strategies in Poland: An adaptive governance approach
Authors: Ćwiklicki Marek , Mirzyńska Anna , Żabiński Michał
Published: June 2024

A new concept charting a new direction for regional socio -economic development in the early 2020s is the circular economy (CE). The novelty means that there is no empirically verified methodology for implementation, and therefore, the extent and scope of incorporating CE into regional declarations and actions will vary. For regions, structured activities should follow the adopted development strategy. Therefore, based on an analysis of the invocation of the CE concept in elements of the strategic management model, included in the regional development strategy (2018–2021), it is possible to determine the degree of its structuring. For this purpose, content analysis and correlation analysis were used. The study aims to explain differences in the institutionalisation of CE in voivodeship development strategies in Poland. The article hypothesises that a high level of CE structuring is correlated with its definition in the strategy and also the state of the environment in the region, and explains the variation in CE institutionalisation using adaptive governance theory. We conclude, based on the results, that regions with higher environmental pollution use CE in more detail in regional development strategies.
The mediating role of dynamic capability between sustainable development and competitive advantage in tourism enterprises in Henan Province (China)
Authors: Wu Yuxin , Hizam-Hanafiah Mohd , Zhang Yin
Published: June 2024

Objective: This study explores the structural relationships between sustainable development and competitive advantage in tourism enterprises, along with the mediating role of dynamic capability, especially following the impact of COVID-19. Design/Method/Approach: An online questionnaire survey was conducted to collect 430 valid primary data sets from middle and senior managers in Henan tourism enterprises. Covariance-based structural equation modeling was utilized to test the direct effect, while the bootstrap method was used for testing mediating effects. Findings: The results reveal that sustainable development has a significant impact on the competitive advantage of tourism enterprises from three sustainability dimensions: economic, environmental and social. Meanwhile, dynamic capabilities represented by adaptive, absorptive and innovative capacities play a mediating role between them. Conclusions/Recommendation: The reshaping of the tourism industry by COVID-19 requires practitioners to take dynamic capability seriously in an uncertain environment. The higher demand for sustainability from tourists after the pandemic also suggests that improvements are a viable way for tourism enterprises to restore and cultivate competitive advantage. Originality/ Value: This study focuses on public health emergencies which are scarce in tourism crisis research (Duan et al., 2021). In addition, it is designed to help managers identify elements that can be used as internal drivers (Wang, 2021) showing how firms can incorporate sustainable development into strategic management, as this is still lacking (Zhang et al., 2020) in practice.

Published: June 2024

Existing literature documents how older refugees are at risk of social exclusion and isolation, yet few researchers have investigated the social inclusion of recently (re)settled older Syrian refugees in Canada. Here we apply the social inclusion model to older migrants to analyze the social inclusion of 360 Syrian refugee older adults (51+ years) in Canada. Results indicate that older Syrian refugees tend to have good health, a strong sense of belonging, regular communication with others, and supportive relationships; therefore, they are likely to experience social inclusion, despite education and language challenges. We conclude by discussing the positive structural elements in their resettlement experiences.
The problems of the theory of the reference of signs in modern linguistics
Authors: Chilingaryan Kamo Pavelovich
Published: June 2024

The subject of the study is the history of the development and current state of the theory of reference, which reflects a variety of approaches and concepts. Some researchers believe that reference is a purely semantic phenomenon, while others emphasize the importance of context and pragmatics for understanding referentiality. The issue of the influence of cultural and social factors on reference in various languages is also being actively investigated. The history of the development of the theory of reference began with the works of Gottlob Frege and Bertrand Russell at the beginning of the 20th century. Frege introduced the concept of semantic reference, arguing that every word has its own referent in the world. Russell developed this idea by proposing a theory of descriptions, according to which words indicate objects by describing their characteristics. The works of Ludwig Wittgenstein and Donald Davidson played an important role in the further development of the theory of reference. Wittgenstein proposed the concept of language games, arguing that reference depends on the context and use of a word in a certain situation. Davidson developed the theory of truth, according to which reference is determined through the connection between language and the world. The pragmatic and cognitive aspects of research methodology are important for the successful conduct of scientific research. The referential nature of signs plays a key role in this process, ensuring effective presentation and communication of research results. The scientific novelty of the research lies in a comprehensive examination of the classical works of philosophers, semiotics and linguists, including Plato, Aristotle, Charles Pierce, Ferdinand de Saussure and Umberto Eco, on the theory of reference. One of the key concepts in the study of sign systems is referential. Referentiality allows to associate words with specific objects and understand their meaning. One of the most relevant areas of research in the field of reference is the study of ways in which linguistic units interact with the context and situation of communication. This allows for a deeper understanding of the processes of notation and interpretation in language, as well as the development of new theoretical models explaining these processes. Thus, scientific novelty in the study of the referentiality of signs continues to be relevant and important for the development of linguistics and related disciplines. The author's contribution in this area may lead to new discoveries and understanding of the mechanisms of linguistic communication.

The media space is the most dynamic and rapidly developing not only technological, but also economic, cultural, social and political phenomenon of our time, and new communication channels are being formed in the global digital network. The purpose of the article is to analyze new media as a subject of the political process. The subject is new media, and the object is the cultural and political identification of an individual in new media. The novelty of the work lies in the fact that new media are an innovative and extremely important tool in determining cultural and political identity. Countries belong to the same civilization, which means that their culture is based on identical values – this is of fundamental importance, since the effectiveness of the imposed system of values and norms can be realized in a particular country only if the tasks being disseminated are consonant with the values of society. Conceptual, phenomenological and sociolinguistic analysis, the method of system analysis, and the historical and cultural method were used as methods and approaches.  As a result of a comprehensive analysis, the following conclusions were drawn: the disseminated values can be effective only if they are in tune with the civilizational model of the region, and on the contrary, the imposed foundations will not effectively affect society if they contradict its civilizational identification and cultural and political affiliation. The actions of an individual and society as a whole are determined by his self-identification, therefore, a political course can be effective in a particular country if the tasks being implemented are consonant with the values of society. This study may be useful for researchers studying communication in the digital environment, the impact of new media on the agenda, the realization of political goals through online media, as well as for international journalists, diplomats, political scientists and media researchers when writing analytical materials on topics related to the working concepts of the current study.
Steady Versus Unsteady Pneumatic Flow Control and Aspects of Practical Integration

Published: June 2024

A systematic study that compares the performance of flow control using steady and unsteady actuation is presented. A family of convergent–divergent nozzles is derived from the fluidic oscillator actuators developed at NASA to produce a set of constant-blowing actuators. The performance of the steady-blowing actuators is compared with that of the original fluidic oscillator using computational fluid dynamics. The flow control characteristics are first established for the actuators in a bench-test setting. Aerodynamic applications for a set of airplane configurations and flight objectives are then used to evaluate the relative flow control performance of the various actuators at realistic flight conditions using consistent actuator layouts. In some cases, where space availability is the prime determinant of system integration, the only viable flow control solution for achieving design targets is provided by constant-blowing actuators. Wind tunnel assessment is also performed for steady and unsteady actuators embedded in a high-lift wind-tunnel model. As the aviation industry seeks to develop the framework for optimal integration of flow control technology into flight vehicles, the study also addresses issues of practical airplane implementations in view of the underlying differences between the steady and unsteady modes of pneumatic actuation.

The next generation of aircraft is likely to exhibit a breadth of aeromechanic and aeroelastic behaviors that will be exacerbated by the turbulent flows generated in urban environments. Exploitation of novel flow control technologies will be critical in offering greater control authority to enable this new generation of aerial vehicles for faster, safer, and more efficient flight. This study experimentally investigates the efficacy of a mini-tab active flow control device using a novel dynamic test rig. Under steady conditions, the mini-tab response exhibited nonlinearity with deployment height. Under dynamic conditions, the lift and pitching moments displayed hysteresis around their quasi-steady counterparts at low reduced frequencies ([Formula: see text]) but displayed significant deviations at middle to high reduced frequencies ([Formula: see text] to 0.31) due to the formation of a tab vortex that propagates downstream. It was demonstrated, for the first time experimentally, that mini-tab dynamic performance is insensitive to unsteady airfoil motions in pitch and plunge—representative of flutter onset. Finally, an existing mini-tab model was extended to capture vortex formation on the upper and lower airfoil surfaces and modified to incorporate mini-tab rate-dependence on vortex initiation. The model showed good agreement with experimental data in both periodic and transient scenarios.

Published: June 2024

This paper introduces the technology and performance of a new sandwich structure consisting of carbon fiber composite face sheets, a polyimide foam core, and an aluminum honeycomb panel with both heat insulation and load-bearing functions. The heat-resistant performance of the sandwich structure was evaluated. The vacuum thermal conductivity of the sandwich structure in the vertical direction ranges from 0.54 to [Formula: see text] with increasing temperature from [Formula: see text] to 135°C. A multilayer finite element model of carbon fiber cloth, polyimide foam, and aluminum honeycomb was established. Finally, a comprehensive evaluation of the mechanical and thermal insulation performance of the sandwich structure was conducted through random vibration testing and thermal vacuum testing. The results showed that the sandwich structure had good stiffness and thermal insulation performance, successfully verifying the effectiveness of the collaborative design.
Robust Adaptive Control of Linear Parameter-Varying Systems with Unmatched Uncertainties

In control of aerospace systems with large operating envelopes, it is often necessary to adjust the desired dynamics according to operating conditions. This paper presents a robust adaptive control architecture for linear parameter-varying (LPV) systems that allows for the desired dynamics to be systematically scheduled, while being able to handle a broad class of uncertainties, both matched and unmatched, which can depend on both time and states. The proposed controller adopts an [Formula: see text] adaptive control architecture for designing the adaptive control law and peak-to-peak gain (PPG) minimization for designing the robust control law to mitigate the effect of unmatched uncertainties. Leveraging the PPG bound of a LPV system, we derive transient and steady-state performance bounds in terms of the input and output signals of the actual closed-loop system with respect to a nominal system. The proposed control architecture is applied to control the longitudinal motion of an F-16 aircraft operating within a large envelope. Simulation results using both LPV and fully nonlinear models validate the efficacy of the proposed method.
