THEORETICAL APPROACHES TO MOTIVATION MANAGEMENT DEVELOPING THE POTENTIAL OF THE ENTERPRISE IN CIRCULAR ECONOMY CONDITIONS
Authors:   State University "Kyiv Aviation Institute", Arefeva Olena , Onopriіenko Dmytro ,   State University "Kyiv Aviation Institute"
Published: February 2025

The article is devoted to the extremely urgent problem of motivational management of the potential of enterprises operating on closed-loop technologies. The article explores different approaches to the essence and content of motivation, summarizes theoretical models of motivational influence on people's activities, considers internal and external factors of motivation and the process of motivational management in the organization. The authors propose a schematic diagram of the motivation system, mechanisms and a model of motivational management of the enterprise's potential in the conditions of a circular economy. The authors conclude that there is no single approach to the interpretation of motivation among the scientific community. Motivation is considered: as a set of motives that motivate people to work to achieve a goal; as a process of stimulating employees to effective activity to achieve the goals of the organization; as the desire of employees to satisfy their needs through work or as a set of internal and external driving forces that motivate people to work. The author's vision of motivation is that its source is internal and external factors that motivate people to work effectively to achieve the goals of the organization through the desire to satisfy their own needs. At the same time, the emergence and satisfaction of needs is the most important factor of motivation. The authors substantiate that motivation as one of the most important management functions plays a key role in the overall management system in the conditions of a circular economy. In development of this vision, the authors present a model of the motivation system of the organization's personnel, the essence of which is the widespread use of incentives (stimulation) with the simultaneous use of internal motives of employees in order to achieve the goals of the organization through the satisfaction of their needs. The article also substantiates the mechanism of motivational management of the enterprise's potential, which is formed through the targeted systematic application of internal and external motivational elements by management entities. In order to increase the synergistic effect, the authors proposed a principle model of a motivational management system for the enterprise's potential in a circular economy, the main feature of which is the formation of environmental awareness, creativity, imagination, and innovative organizational culture among the enterprise's personnel.

Authors: Kavrayici Ceyhun , Shikhkamalova Venera , Tamdogan Evliyaoglu Ahu
Published: February 2025

This study examined the relationship between psychological capital and professional resilience among public school teachers. It aimed to determine the extent to which psychological capital predicts professional resilience. The quantitative study used a correlational survey model, with a sample of 410 teachers from Bursa Province, Turkey, during the 2022-2023 academic year. Data were collected using a Personal Information Form, the "Psychological Capital Perception Scale", and the "Teacher Professional Resilience Scale", and analyzed using SPSS 22. Descriptive statistics, Pearson's correlation, and regression analysis were conducted. Results showed positive, significant relationships between psychological capital and professional resilience. Teachers rated their professional resilience as "moderate." While hope, efficacy, and resilience (but not optimism) were predictors of professional resilience, overall perceptions of both psychological capital and professional resilience were not particularly high. The study suggests a need to strengthen teachers' psychological capital and enhance their professional resilience.

Authors: Righi Selene , Viganò Elena
Published: February 2025

The importance of research and innovation is crucial for addressing the challenges posed by evolving climatic and environmental conditions, along with the urgent need to mitigate greenhouse gas emissions and to deal with unstable markets.To establish Sustainable Agri-Food Systems, in environmental, social, and economic terms, it is essential to ensure access to technologies that can reduce biological and market risks.The objective of this paper is to understand how different factors influence the innovativeness of organic farmers in the Marche region, in Italy, with a particular focus on the adoption of a digital tool, Decision Support System (DSS).The analysis, developed through the application of the SEM model to a sample of organic farmers, highlights the significant role of support services in facilitating the implementation of innovations. Therefore, it is important for policymakers, especially at the regional level, to define specific and coherent measures that incentivize the adoption of innovations.
The role of EIP-AGRI Operational Groups as a driver for innovation in viticulture
Authors: Mignani Chiara , Ferrara Annapia , Tomasi Sabrina , Moretti Michele , Cavicchi Alessio
Published: February 2025

European policies play a crucial role in helping farms and stakeholders in the agri-food sectors to proactively engage in digital and environmental transitions. Among them, the European Partnership for Innovation in Agriculture (EIP-AGRI), which was established in 2014, has proven significant in promoting sustainable production models and value chains in Europe. Operational Groups (OGs) within the Partnership provide "interactive innovation" platforms in which research institutions work with farmers, advisors, businesses, NGOs and other interest groups to co-create innovative solutions for agriculture and forestry as well as rural communities; the rationale is that when farmers and foresters are engaged in the process, the solutions are more likely to be based on their concrete reality and thus relevant.  While the benefits of the participatory, multi-actor and bottom-up approach of OGs have been widely acknowledged, little is known about the drivers and barriers influencing the process. This contribution explores their role in the wine sector, applying a mixed methods approach to analyse the perceptions of OG stakeholders from different Italian regions. Interviewees have been asked to what extent they believe the EIP-AGRI OGs serve as drivers of innovation and provide a network able to foster knowledge exchange, and what they perceive to be their barriers to innovation. By addressing this knowledge gap, this study will provide some insights and good practices to improve EIP-AGRI policies at regional, national and European levels.

Authors: Pezzotta Giorgia , Masiero Giuliano , Malagnino Alessia , Bozzo Samantha , Brescacin Alessandra , Carrara Giulia , Zago Mauro
Published: February 2025

Background: There still is reluctance among surgeons when it comes to using bedside US in their daily clinical practice, except for very specific fields.Generally, the decision-making process relies on imaging techniques (e.g. CT, MRI). This may lead to a latency of execution, and consequently to a delay in decision making.Objectives: The purpose of this study is to assess the economic impact of systematic and routine use of surgeon-performed point-of-care US (SP-POCUS) in the everyday activities of a surgical department, both for urgent and elective cases.Methods: We conducted a cost-benefit analysis comparing the incremental costs and savings of diagnostic strategies based on alternative procedures to bedside US. The dataset refers to 478 SP-POCUS performed at the General Surgery Department of Policlinico San Pietro (Bergamo, Italy) between January 2018 and February 2020. The alternatives to SP-POCUS were computed tomography (CT), X-ray (RX), magnetic resonance imaging (MRI), and US performed by the Radiologist.Per-exam costs, including personnel time expenditure, were calculated.Results: The economic evaluation revealed that the use of SP-POCUS allowed the hospital to generate €355 net savings per patient, mainly from avoided hospitalizations, fewer hospital days and hours of operating room.Extrapolating these results to a wider scenario, in a similar setting they could have represented a potential annual savings of more than €1.1 million for the Regional healthcare system in Lombardy, and more than €5.7 millions for the whole NHS in Italy.Conclusions: We provided evidence that SP-POCUS may generate important costs savings for health care providers, as it represents the most cost-effective initial diagnostic procedure compared to standard alternatives.The wide applicability of SP-POCUS could be obtained at rather negligible costs for investment in staff training.

La gestione del personale amministrativo nel Sistema Sanitario Nazionale (SSN) italiano è una sfida critica spesso trascurata. Tuttavia, in un contesto di imminenti pensionamenti e rivoluzioni tecnologiche, è pressante la necessità di attrarre personale più giovane, qualificato e digitalmente competente, ridefinendo il profilo amministrativo verso una gestione più efficiente e innovativa. Questo studio offre la prima analisi del personale amministrativo nel contesto del SSN, al servizio di una efficace attività di pianificazione dei fabbisogni. Il contributo propone metriche di benchmarking a livello interaziendale e nel confronto tra unità operative amministrative e ne mostra una possibile applicazione in un'azienda sanitaria.
Surfing tra SSN e spesa privata: impatti sui tempi di attesa dei ricoveri oncologici
Authors: Russo Antonio Giampiero , Bergamaschi Walter , Longo Francesco
Published: February 2025

Questo studio indaga se il cosiddetto "surfing" tra il Servizio Sanitario Nazionale (SSN) e la spesa privata possa ridurre i tempi di attesa per i ricoveri oncologici, minando il principio di equità nell'accesso alle cure.L'obiettivo è verificare se, nonostante il mix tra spesa pubblica e privata, il SSN riesca a garantire equità di accesso e presa in carico globale per percorsi di cura critici, come gli interventi chirurgici oncologici, dove i tempi di attesa possono avere un impatto significativo sugli esiti clinici.Lo studio si concentra su una coorte di 41.408 ricoveri oncologici programmati nel periodo 2022-2023, e analizza leprestazioni diagnostiche preoperatorie necessarie per l'inserimento in lista d'attesa chirurgica, erogate in regime SSN, o privato (distinto fra erogatori pubblici o privati accreditati che operano sia in regime pubblico sia di solvenza ed erogatori privati autorizzati che operano solo in regime privato). L'analisi evidenzia che il 68,4% delle prestazioni preoperatorie è stato erogato in regime SSN, il 12,1% in regime di libera professione intramuraria o ricorrendo all'area di solvenza degli erogatori pubblici o privati accreditati e a contratto per il SSR, e il 19,5% a pagamento diretto dai pazienti o tramite assicurazioni private verso erogatori solo autorizzati e che svolgono esclusivamente attività privata, con una maggiore incidenza del ricorso alla solvenza nelle strutture private accreditate rispetto a quelle pubbliche.I risultati mostrano che i pazienti che accedono privatamente a tutte le prestazioni preoperatorie hanno un vantaggio in termini di tempi di attesa rispetto a quelli che accedono solo al SSN, mentre i pazienti che fanno "surfing" non sembrano avere vantaggi significativi. Il sistema sembra quindi mantenere, nel complesso, un profilo di equità accettabile, con limitate distorsioni nei tempi di attesa complessivi.Il lavoro conclude che il ricorso alla solvenza ha un impatto limitato sui tempi di attesa per i pazienti oncologici, pur evidenziando la necessità di regolamentazioni più rigorose per garantire l'equità di accesso alle prestazioni preoperatorie critiche.

Authors: Malatto Alessandro , Gandullia Luca , Leporatti Lucia , Montefiori Marcello , Petralia Paolo
Published: February 2025

Background. L'asma è una patologia cronica molto diffusa a livello globale che determina elevati costi economici e sociali.Objective. L'obiettivo dello studio è stimare i costi diretti riconducibili ai pazienti asmatici, focalizzandosi sulle eventuali differenze in termini di assorbimento delle risorse tra pazienti affetti da asma grave e non grave.Methods. A questo fine è stato adottato un approccio data-driven per condurre un'analisi economico-quantitativa sui dati amministrativi dell'Azienda Sanitaria Locale n. 4 dellaRegione Liguria. Quindi, dopo aver individuato un campione di pazienti asmatici e distinto quelli con forma grave, sono stati calcolati i costi per ospedalizzazioni, esami e test diagnostici, nonché quelli relativi alla spesa farmaceutica, tenendo conto della gravità della patologia.Results. Le analisi sono state condotte su un campione di oltre 7 mila pazienti, con un 11% di pazienti affetti da asma grave. In media, i costi diretti annui per paziente ammontano a € 1.800, e la spesa per farmaci ne rappresenta il 52%. Ogni anno, i pazienti con asma grave costano al SSN quasi € 1.000 in più rispetto ai pazienti affetti da asma lieve (€ 2.644 vs € 1.689, p < 0,001). Questa differenza è principalmente imputabile al consumo difarmaci per le sindromi ostruttive delle vie respiratorie.Conclusion. La gravità della patologia asmatica è un fattore altamente predittivo dei costi diretti associati alla gestione della patologia. Il contributo maggiore di questo differenziale in termini di costi risiede nel più intensotrattamento farmacologico della patologia, necessario per mantenere sotto controllo i sintomi e scongiurare le esacerbazioni.

Bookkeeping is one of the important things done by every business actor, but it is often ignored by small business actors, especially those in Girian Atas Village. This happens because small business actors do not understand how to make bookkeeping, have not applied the concept of business entities, do not know how to calculate selling prices in accordance with cost accounting theory. Based on this reality, it is necessary to conduct training activities on Bookkeeping and Determination of Selling Price in Small and Medium Enterprises in Girian Atas Village. The activity was carried out in two stages. First, conduct training on bookkeeping and determination of cost of goods sold and selling price. Second, conducting evaluation and monitoring, to see the extent of the results of financial records of SMEs. The results of this activity have an impact on increasing knowledge and understanding of accounting and determining selling prices. Business actors have also been able to make simple financial statements, namely income statements, statements of changes in capital, and balance sheets. This is a good thing, because they can fulfill one of the requirements to apply for a credit loan at the bank, which will certainly help increase the capital of their business.

Published: February 2025

The rapid development of the gaming industry has prompted the integration of programming education into vocational education curricula, yet manual assessment of student projects remains a significant constraint. This study proposes a C#-based game programming interface with automatic assessment using unit testing. Students receive learning materials from teachers for self-directed study, employing interface development methods based on Test-Driven Development (TDD) principles and prototype research methods. Research results demonstrate the success of automated assessment, enhancing the efficiency of student evaluations and the quality of game programming education. Academic data confirms improved student learning outcomes. Advantages of automated assessment include time efficiency for teachers, consistency, prompt feedback, support for self-directed learning, TDD implementation, and overall enhancement of learning quality. Data analysis of programming modules (MP) and test modules (MT) indicates the effectiveness of the C#-based game programming interface with TDD. Automated assessment eliminates the burden of manual correction, allowing teachers to focus on pedagogical aspects. Consistency is evident in uniform outcomes across all modules. Prompt feedback provides students with instant improvement opportunities, while self-directed learning support and TDD implementation are reflected in the success of test modules. In conclusion, this innovation effectively addresses assessment challenges in game programming education within vocational settings.

The development of micro, small and medium enterprises (MSME) play a vital role in improving the local economy and expanding economic opportunities for the community. One effective strategy in supporting the growth of MSME is through creating business carts that can function as a mobile platform for selling products or services. This research aims to examine the process of making MSME carts with a focus on design innovation, materials used, and efficient and environmentally friendly production methods. Research methods involve literature analysis, field surveys, and interviews with relevant stakeholders. The research results show that the use of appropriate technology and materials can increase the durability, safety and aesthetics of MSME carts, while the use of efficient production methods can reduce production costs and speed up processing time. The practical implications of this research are to provide practical guidance for MSME in choosing designs, materials and production methods that suit their needs and to encourage the government and related institutions to provide adequate support and facilities for the development of MSMEs through the manufacture of business carts. Thus, this research has the potential to make a significant contribution to increasing the competitiveness of MSME  and strengthening the local economy in a sustainable manner.
SOCIALIZATION OF ADMINISTRATIVE RECORDS AND FINANCIAL MANAGEMENT OF VILLAGE-OWNED ENTERPRISES IN PUKDALE VILLAGE
Authors: Alexander Wewo Jeremia
Published: February 2025

This activity was motivated by the fact that administrative records and financial management in Village-Owned Enterprises had not been properly and properly organized. This service aims to provide an explanation of administrative recording and financial management of village-owned enterprises (BUMDes) located in Pukdale Village. The method used is socialization, namely the service provider provides material and then has a question and answer discussion. The results of the service and discussion found that administrative recording activities consist of expeditions in the form of activities to record any information sent or received, both for internal and external purposes and archiving is a process of systematically organizing information storage so that it can be easily and quickly found if needed while financial management includes planning, organizing, implementing, and controlling financial activities. The suggestion given in this service is that the socialization that has been delivered by the dedication should be carried out by all village officials so as to create a quality pattern of administrative recording and financial management.
The Relationship Between Structuration Theory and Agency According to Giddens and Walters
Authors: Dayrobi Mhd. , Usqo Hanafi Urwatil , Lubis Fauziah
Published: February 2025

This research aims to understand social action through the lens of Structuration and Agency Theory, with a special focus on the thought of Anthony Giddens and Malcolm Walters. Giddens' Structuration Theory emphasizes the dialectical relationship between agency (individual action) and structure (social rules and resources), where structure not only constrains but also enables action. The concept of duality of structure shows that structure is both the medium and the result of social action. Walters expands this concept by highlighting how individuals, through reflexive capacities, can reproduce or change social structures. This research uses library research methods. The research results show that a deeper understanding of the interaction between agency and structure can enrich sociological analyzes of social change and the sustainability of social structures.
Notkun á bitastangalíkani til að herma burðarþolstilraunir á járnbentum steinsteyptum burðarveggjum

Published: February 2025

Járnbentir steinsteyptir burðarveggir eru algengasta burðarformið í íslenskum húsbyggingum. Frá ómunatíð hafa kröftugir jarðskjálftar reglulega riðið yfir í helstu brotabeltum landsins og reynt á menn, mannvirki og innviði. Til að meta áhrif jarðskjálfta á mannvirki er gagnlegt að hafa aðgang að áreiðanlegum reiknilíkönum sem eru mismunandi eftir því hvers konar mannvirki er verið að greina. Svokallað bitastangalíkan hefur á undanförnum árum verið þróað erlendis til að herma hegðun steinsteyptra burðarveggja. Reiknilíkan af þessari gerð var nýlega notað við Háskóla Íslands til að herma tilraunir þar sem tvær gerðir af stoðveggjum voru álagsprófaðar. Í jarðskjálftaverkfræði er þekkt að halda svokallaðar blindtilraunakeppnir þar sem burðarvirki eru álagsprófuð við stigvaxandi álag. Fyrirkomulagið í slíkri keppni er þannig að þátttakendur fá allar upplýsingar um hönnun prófstykkis en eiga síðan að nota eigin reiknilíkön til að spá fyrir hegðun og brotmynd burðarvirkisins án þess að þekkja tilraunaniðurstöður. Nýlega fór fram alþjóðleg tvískipt blindtilraunakeppni. Fyrri hlutinn var haldinn árið 2022 í UCLouvain háskólanum í Belgíu, þar sem tveir eins U-laga veggir úr járnbentri steinsteypu, með lyftukjarna í þriggja hæða byggingu sem fyrirmynd, voru prófaðir með stigvaxandi stöðuálagi gangvart bæði beygju- og vinduáraun. Seinni hluti keppninnar fór svo fram í Portúgal árið 2024. Þar var samskonar U-laga burðarveggur prófaður á hristiborði gagnvart kvikri jarðskjálftahreyfingu með mismunandi ákefð. Rannsóknahópur frá Háskóla Íslands tók þátt í þessum seinni hluta keppninnar og notaði bitastangalíkan og opna hugbúnaðinn OpenSees til að spá fyrir jarðskjálftasvörun prófstykkisins. Í greininni er fjallað um notkun á bitastangalíkaninu til að herma tilraunaniðurstöður úr stoðveggjarannsókninni og til að spá fyrir um niðurstöður úr seinni hluta blindtilraunakeppninnar. Eftir að tilraunaniðurstöður lágu fyrir var líkanið endurbætt til ná betri árangri. Heilt yfir gekk vel að herma niðurstöður úr öllum tilraununum og mikilvæg reynsla og aukin færni fékkst úr rannsóknaverkefninu.

K. F. Karjalainen’s Eastern Khanty Text Collection (1899–1901)
Authors: Csepregi Márta
Published: February 2025

During fieldwork conducted between 1898 and 1902 in Western Siberia, Kustaa Fredrik Karjalainen traveled through the entire area where Khanty (also known as Ostyak) was spoken. He collected an abundant amount of lexical material from each dialect, and in addition he made grammatical sketches and collected folklore texts. Due to Karjalainen’s untimely death, he was unable to publish his collection. The Eastern Khanty text collection presented in this work is the hitherto-unpublished last part of Karjalainen’s legacy. It is of great significance from the point of view of both linguistics and folkloristics, as it is the oldest Eastern Khanty text corpus, and it documents genres that were previously unknown.
The present work comprises a phonematic transcription of the manuscript, its English translation, and notes explaining linguistic and folklore phenomena. In addition, it contains a linguistic description of three Eastern Khanty dialects (Tremjugan, Vasjugan, Likrisovo), and word lists of these based on the texts. A detailed introduction to the research history of Khanty and a summary of the contribution of the texts to ethnographic research place the presently published source into a wider context and set out further potential directions for research.
Impact of Sibling Structure on Emotional Maturity and Psychological Well-being in Youth: A Comparative Study
Authors: Patil Maithili P , V Dr. Hemanthkumara
Published: February 2025

This study investigates the influence of sibling structure on emotional maturity and psychological well-being among youth aged 18-25, focusing on three groups: those with biological siblings, single biological individuals, and single adopted individuals. A sample of 300 participants was assessed using the Emotional Maturity Scale and Ryff Psychological Well-being Scale. The results from one-way ANOVA and Pearson correlation analysis revealed significant differences in emotional maturity and psychological well-being based on sibling structure. Youth with biological siblings exhibited higher levels of both emotional maturity and psychological well-being compared to single biological and single adopted individuals. Additionally, a strong positive correlation was found between emotional maturity and psychological well-being, indicating that greater emotional maturity is associated with better psychological well-being. These findings highlight the critical role of sibling relationships in fostering emotional and psychological development and suggest the need for tailored interventions that consider diverse sibling configurations.
An extension of Wilson's Theorem
Authors: Butov Gennady
Published: February 2025

The aim of this work is to optimize the existing formula based on Wilson's theorem to reduce the magnitude of the computation results. Wilson's theorem states: if p is a prime number, then (p-1)! + 1 is divisible by p (p-1)! ≡ -1 (mod p). The function (p-1)! increases very rapidly and reaches huge values. When the values of p are large, the calculations become resource-intensive, so it is necessary to reduce the upper limit of the calculation results.

Introduction

Changes in cognitive abilities including memory accompany normal aging, and certain types of memory are particularly susceptible to age-related change. The ability to link aspects of an experience to form one cohesive memory, called relational memory, is essential to normal memory throughout the lifespan. Relational memory facilitates the binding of arbitrarily related stimuli and encompasses all manner of relations (spatial, associative, sequential). Prior work has studied differences in relational memory associated with aging but has investigated specific aspects of relational memory in a siloed fashion: earlier studies typically have not simultaneously assessed multiple aspects of relational memory in the same participants in the same paradigm.

Methods

In the current study, multiple aspects of relational memory were simultaneously compared between healthy younger adults (19–35 years, n = 40) and healthy older adults (65–77 years, n = 40).

Results

We found that older adults had reduced memory performance relative to younger adults on each condition of the memory task (item condition, space condition, re-pair condition, and time condition), and there was a condition-by-age group interaction such that differences were greatest for the time and space conditions.

Discussion

We found age-related differences between young and older adults on a task simultaneously testing multiple types of relational memory with young adults performing better overall. Additionally, we observed condition-level interactions such that the age-related differences were greater for the time and space conditions than the re-pair condition. Together, these findings underscore the importance of measuring memory for all manner of relations using the same study format to achieve a thorough characterization of the complex nuances of relational memory performance across the lifespan.

African swine fever (ASF) is a devastating viral hemorrhagic disease caused by the ASF virus (ASFV) that can kill up to 100% of domestic pigs and wild boars. The domestic pig industry in Rwanda is highly threatened by ASF, with several outbreaks reported yearly to the World Organization for Animal Health. Despite the endemic status, no ASFV from Rwanda has been genetically characterized. This study reports, for the first time, the ASFV genotypes causing outbreaks in Rwanda. The ASF confirmation was performed by polymerase chain reaction followed by molecular characterization of the causative ASFV by partial and complete genome sequencing and phylogenetic reconstruction. After genetic analysis, the ASFV strains responsible for the 2021 outbreak in eastern Rwanda clustered within genotype II, while the strain from the 2023 outbreak in northern Rwanda clustered within genotype IX. The extension of the geographical range of genotype II in eastern Africa is of concern. In the countries of the East African Community, this ASFV genotype was reported for the first time in Tanzania at the Tanzania-Malawi border in 2011, followed by a relentless spread of the virus northwards along major highways within Tanzania before the detection of this genotype in Rwanda in 2021. This ASFV genotype will most likely reach other eastern African countries threatening the regional domestic pig industry. The ongoing spread of ASFV genotypes II and IX across Africa impacts food and nutritional security, and hinders the realization of the United Nations Sustainable Development Goal 1 (No Poverty) and·Goal 2 (Zero hunger). The results of this study call for science-driven and regional approaches to enable the timely identification of ASF outbreaks for effective prevention and containment.

Precision Farming (PF) in vineyards represents an innovative approach to vine cultivation that leverages the advantages of the latest technologies to optimize resource use and improve overall field management. This study investigates the application of PF techniques in a vineyard, focusing on sensor-based decision-making for autonomous driving. The goal of this research is to define a repeatable methodology for virtual testing of autonomous driving operations in a vineyard, considering realistic scenarios, efficient control architectures, and reliable sensors. The simulation scenario was created to replicate the conditions of a real vineyard, including elevation, banking profiles, and vine positioning. This provides a safe environment for training operators and testing tools such as sensors, algorithms, or controllers. This study also proposes an efficient control scheme, implemented as a state machine, to autonomously drive the tractor during two distinct phases of the navigation process: between rows and out of the field. The implementation demonstrates improvements in trajectory-following precision while reducing the intervention required by the farmer. The proposed system was extensively tested in a virtual environment, with a particular focus on evaluating the effects of micro and macro terrain irregularities on the results. A key feature of the control framework is its ability to achieve adequate accuracy while minimizing the number of sensors used, relying on a configuration of a Global Navigation Satellite System (GNSS) and an Inertial Measurement Unit (IMU) as a cost-effective solution. This minimal-sensor approach, which includes a state machine designed to seamlessly transition between in-field and out-of-field operations, balances performance and cost efficiency. The system was validated through a wide range of simulations, highlighting its robustness and adaptability to various terrain conditions. The main contributions of this work include the high fidelity of the simulation scenario, the efficient integration of the control algorithm and sensors for the two navigation phases, and the detailed analysis of terrain conditions. Together, these elements form a robust framework for testing autonomous tractor operations in vineyards.

This study hypothesized that different base fertilizer application has different effects on improving the efficiency of maize water utilization and promoting maize growth. Utilizing field positioning sloping farmland micro-zone experiments, six distinct types of base fertilizers were designed: a control group without fertilization (CK), chemical fertilizer alone (T1), a mixture of local farmyard manure (40% pine needles and 60% livestock manure, T2), a 50% reduction in chemical fertilizer combined with farmyard manure (T3), the incorporation of crushed straw through deep plowing (T4), and the fermentation of crushed straw mixed with urea before field application (T5). The results indicate that, compared to the CK treatment, the T3 and T5 treatments significantly enhanced soil moisture content, with increases ranging from 4.06% to 18.67% during the normal year (2023) and the drought year (2024), respectively. Additionally, the water utilization efficiency of maize was improved significantly, with values of 35.38% and 41.54%, and the yield increased by 12.30% to 25.92%. The maize yields under T3 and T5 treatments reached 12.19 and 13.31t/ha, respectively. Therefore, we propose that crushing straw and incorporating urea and water for fermentation as a base fertilizer in maize fields can ensure efficient water use in this region, leading to higher yields.

Myotis yumanensis is a small insectivorous bat distributed in Western North America and is susceptible to white-nose syndrome, a devastating fungal disease. Effective management of the disease in M. yumanensis requires an understanding of its population structure to identify possible routes and barriers of disease transmission. Here we used nine microsatellite loci to investigate genetic variation among 336 M. yumanensis from 10 locations in Western Canada. Our analyses revealed high genetic diversity and low but statistically significant genetic differentiation among several geographic populations. Interestingly, though geographically it was not the most distant, the Lillooet population showed the highest genetic differentiation from others, suggesting factors other than geographic distance also contributed to gene flow in this species. While white-nose syndrome has been reported in M. yumanensis populations in neighbouring Washington State in the United States of America, as of 2023, the causative pathogen was not detected on the wings of our analyzed 336 M. yumanensis bats in Western Canada. However, continuing monitoring is required to provide the most updated information about the white-nose syndrome status in these populations. The knowledge of M. yumanensis population structure in Western Canada will help develop effective management strategies for protecting this bat species from white-nose syndrome.

The successful application of primordial germ cells (PGCs) is an ideal method for generating gene-edited birds. However, barriers to efficient DNA transfection in PGCs lead to low transfection efficiency, limiting the generation of genetically modified chickens. The current study utilized chemical transfection and electroporation methods to determine the optimal transfection conditions for the PGC line under feeder- and serum-free medium. Among the tested methods, the Lonza electroporation system exhibited the highest transduction efficiency, with a previously unreported rate of 71.13 ± 1.26%. Optimal transfection conditions were achieved using 4 µg of DNA and 100 µL of EntransterTM-E in 1 × 106 PGCs. Furthermore, the optimal electroporation conditions resulted in low cell death and normal expression of pluripotency-related genes, highlighting the low cytotoxicity. The resulting electroporation models were then used to deliver the enhanced green fluorescent protein (EGFP) gene to the Z chromosome with a Cas9-gRNA plasmid, achieving a 7-day insertion efficiency of 14.63 ± 1.07%. Our study highlights the vast potential of electroporation technology for the transfection of PGCs.

Published: February 2025

The use of parametric models in the architecture, engineering, and construction (AEC) industry has made it possible to create complex and creative building designs. However, this design complexity creates major constructability issues, especially in projects that incorporate prefabricated façade panels. Computational design methods can solve some of these issues; however, such methods do not necessarily include the systematic approach to integrating domain knowledge, which results in inefficiencies in the design and construction processes. This paper introduces how constructability knowledge can be incorporated into computational design process using feature-based modeling (FBM). An ethnographic case study of a high-rise building with complex façade design is presented in this paper. The research identifies the critical geometric constraints that affect constructability and introduces a new three-level taxonomy (Micro, Meso, Macro) for classifying these constraints. The suggested taxonomy is then applied to inform developing a conceptual knowledge-based computational design approach that enables incorporating the insights of domain experts into the design process. Moreover, the research provides a range of external examples to validate the proposed taxonomy. The findings demonstrate the potential of FBM to streamline the design and fabrication of prefabricated façade panels, improving constructability without compromising architectural intent. This study provides a structured methodology that can be applied to enhance design efficiency and reduce construction risks in similar projects.

Published: February 2025

In this study, a modified 3D printer hotend equipped with a load cell, attached to the feeding system, was used to evaluate the effects of filament material composition and printing parameters on the extrusion force required. Four different materials (commercial PLA, pure PLA, wood-PLA with different ratios of wood particles, and wood-PLA with different ratios of thermally modified wood particles) were used for 3D printing, and the feeding resistance was measured. The filament feeder was connected to the extruder hotend via a load cell, which measured the forces required to push the filament through the extruder and the nozzle. Three printing nozzle temperatures of 200, 210, and 220 °C were used. The results show that the printing temperature and the material influence the required extrusion forces, which varied between 1 and 8 N, but the variation was high. With proper optimization and integration into the printer firmware, this setup could also be used to detect nozzle clogging during printing, modify printing parameters during the process, and prevent the uneven extrusion of composite filaments.
