Dietary Inclusion of Defatted Silkworm (Bombyx mori L.) Pupa Meal for Broiler Chickens at Different Ages: Growth Performance, Carcass and Meat Quality Traits
Publication Name: Animals
Publication Date: 2023-01-01
Volume: 13
Issue: 1
Page Range: Unknown
Description:
The present study was conducted to assess the effects of a 4% defatted silkworm (SWM-DEF) meal dietary incorporation into chickens’ diet at different growth stages on growth performances, carcass, and meat quality traits. A total of 90 Ross 308 one-day-old male broiler chickens were randomly allocated into 3 dietary groups of 5 replicated pens/diet (6 chickens/pen). One group was fed a standard soybean-based diet (C); group SWM1 consumed a starter diet (1–10 days of age) including 4% SWM-DEF and then the C diet up to slaughter (11–42 days of age); group SWM2 was fed with the C diet in the starter phase and the 4% SWM-DEF diet up to slaughter. Individual live weight and pen feed intake were determined at the end of each feeding phase: starter, grower, and finisher. Weight gain and FCR were then calculated. At 42 days of age, chickens were slaughtered and carcass traits determined. Leg and breast physico-chemical meat quality was also evaluated. Results confirmed that SWM-DEF could be a possible alternative feed source for chickens since growth performance, carcass, and meat physical traits were overall comparable in the three treatment groups. The feeding stage seemed to play a relevant impact on the sole meat protein content (SWM1 < SMW2 and C; p < 0.001). Concluding, the results available to date indicate that 4% SWM-DEF can be provided to chickens in different growth phases, and the choice of the inclusion period is more an industrial cost-benefit evaluation. From the scientific point of view, however, an administration in the grower-finisher phase rather than in the starter one provided the best meat nutritional quality. Further investigations should focus on the impact on meat fatty acids profile and sensory traits, which are of utmost importance for consumers.

Iconic Arable Weeds: The Significance of Corn Poppy (Papaver rhoeas), Cornflower (Centaurea cyanus), and Field Larkspur (Delphinium consolida) in Hungarian Ethnobotanical and Cultural Heritage
Publication Name: Plants
Publication Date: 2023-01-01
Volume: 12
Issue: 1
Page Range: Unknown
Description:
There are an increasing number of initiatives that recognize arable weed species as an important component of agricultural biodiversity. Such initiatives often focus on declining species that were once abundant and are still well known, but the ethnographic relevance of such species receives little recognition. We carried out an extensive literature review on the medicinal, ornamental, and cultural applications of three selected species, Papaver rhoeas, Centaurea cyanus, and Delphinium consolida, in the relevant Hungarian literature published between 1578 and 2021. We found a great diversity of medicinal usages. While P. rhoeas stands out with its sedative influence, D. consolida was mainly employed to stop bleeding, and C. cyanus was most frequently used to cure eye inflammation. The buds of P. rhoeas were sporadically eaten and its petals were used as a food dye. All species fulfilled ornamental purposes, either as garden plants or gathered in the wild for bouquets. They were essential elements of harvest festivals and religious festivities, particularly in Corpus Christi processions. P. rhoeas was also a part of several children’s games. These wildflowers were regularly depicted in traditional Hungarian folk art. In poetry, P. rhoeas was used as a symbol of burning love or impermanence; C. cyanus was frequently associated with tenderness and faithfulness; while D. consolida regularly emerged as a nostalgic remembrance of the disappearing rural lifestyle. These plants were also used as patriotic symbols in illustrations for faithfulness, loyalty, or homesickness. Our results highlight the deep and prevalent embeddedness of the three iconic weed species studied in the folk culture of the Carpathian Basin. The ethnobotanical and cultural embeddedness of arable weed species should also be considered when efforts and instruments for the conservation of arable weed communities are designed.

Publication Name: Springer Proceedings in Business and Economics
Publication Date: 2023-01-01
Volume: Unknown
Issue: Unknown
Page Range: 335-354
Description:
Sustainable Urban Mobility Planning (SUMP) is one of the key element of the new EU Urban Mobility Framework. The European Commission has offered variety of programs in the previous years, such as the Horizon 2020 to support Member States to promote SUMPs in their region, and still offers funding for range amount of sustainable settlement and transport related projects. At the same time Member States are also keen on to maintain the roll out of SUMPs within their national support program, with public transport, walking and cycling at its heart. In the last decade the authors took part in the development of many SUMPs and since 2020 the authors participated in an international, so called UrbanSCOPE—Urban Sustainable Mobility in focus: student education, community involvement and participative planning, Erasmus+ project, that aim was to improve the quality of teaching in universities, by offering students a methodology in the preparation of a SUMP for a locality in their cities, actively involving local communities and local authorities in the process. During the project educational packages: learning materials for students and teaching guides for lecturers were developed, in order to let understand sustainable mobility better, than before and as well as to experience the rights of participation in the planning of sustainable mobility. With the contribution of the authors new digital tools were also introduced for teachers and students during the COVID’19, that helped to rise the efficiency of planning during restrictions and lock down.

Volume: 50
Issue: 4
Page Range: 1253-1259
Description:
The primary goal of the study is to explore the satisfaction of Hungarian people with food delivery services, which gained popularity during the COVID-19 pandemic, in the post-pandemic period. The publication's main research questions are: to what extent are customers satisfied with the speed of food delivery and the temperature of the delivered meals? The empirical research also analyses whether the speed of delivery influences the customers' attitudes towards their connection with the catering establishments. The survey was carried out between April 10, 2022, and June 30, 2022. The sample is non-representative (N=452), with respondents being selected arbitrarily in Győr-Moson-Sopron County. Data were processed using the IBM SPSS 25.0 statistical software package. During the primary research the authors examined the current food ordering habits of the participants using statistical (descriptive, correlational) analyses. The aim of this study is to identify and evaluate the key factors that influence customer satisfaction and decision-making in the food delivery industry, providing actionable insights for service providers. The topic of the present study is the examination of the customer satisfaction and decision-making of the Hungarian population focusing on the food delivery industry. A comprehensive literature review was conducted to establish a theoretical framework and formulate hypotheses. A survey-based methodology was employed to collect data from consumers and the collected data were analysed using statistical techniques to test the formulated hypotheses and determine the relationships between the identified factors and customer satisfaction. Results and discussions: presentation and analysis of the obtained results. The study concludes that delivery speed, food temperature, price-value ratio, quality, variety and online presence are crucial factors in the customer satisfaction and decision-making in the food delivery industry. Addressing these aspects can help service providers enhance their competitiveness and improve the overall customer experience.

Composting of medicinal and aromatic plant waste: challenges and opportunities
Publication Name: Recent Trends in Solid Waste Management
Publication Date: 2023-01-01
Volume: Unknown
Issue: Unknown
Page Range: 115-136
Description:
Aromatic plants have been extensively used for their medicinal and culinary properties by the cosmetic, pharmaceutical, and food industries. Along with the prosperous development of the herbal industry, however, enormous amounts of solid biomass have been generated, creating an environmental hazard. Since the waste material generated during harvesting, pre-processing, or extraction may retain its nutritional value, it can be converted to compost or vermicompost. Nonetheless, the addition of herbal residues to the feedstock material may negatively influence biodegradation due to the lower nitrogen content, increased lignocellulose content, and the remaining bioactive compounds. Overall, this book chapter discusses the current challenges that herbal waste composting/vermicomposting faces, provides insights into the process optimisation, and summarises the potential beneficial effects of mature compost.

The Theoretical Framework of Sustainable Financial Development Through Literature Outlook
Publication Name: Chemical Engineering Transactions
Publication Date: 2023-01-01
Volume: 107
Issue: Unknown
Page Range: 595-600
Description:
Sustainable development seeks to strike a balance between economic growth, social well-being and environmental protection. It should be integrated into financial development as well. As a consequence, banks are realising changes in their roles, decision-making, and operations. This paper aims to introduce a structured literature outlook about the different interpretations of sustainable financial development (SFD) on micro and macro levels. The literature mapping is focusing on three main contexts. The basic assumption of the paper is that it is crucial to emphasise the importance of country-level economic growth, the indicators used to determine the level of financial development and the resilience of the financial intermediary actors. As a consequence, the paper represents some existing results in terms of these three contexts. This gives the future basis for the efficient interpretation of sustainable financial development aspects in the operation and the decision-making processes of financial institutions and also for policy-making institutions on the macro-level.

Description of three new bat-associated species of hard ticks (Acari, Ixodidae) from Japan
Publication Name: Zookeys
Publication Date: 2023-01-01
Volume: 1180
Issue: Unknown
Page Range: 1-26
Description:
In Eurasia, the geographically most widespread ixodid tick species of the bat families Rhinolophidae Gray, Vespertilionidae Gray, and Miniopteridae Dobson were considered to belong to four species, Ixodes vespertilionis Koch, I. collaris Hornok, I. ariadnae Hor-nok, and I. simplex Neumann. Previous data attest that bat-associated tick species from Eastern Asia show remarkable genetic difference from the above four tick species, but in the absence of detailed morphological comparison these were regarded as conspe-cific. In this study we compensate for this lack of data on three bat-associated tick spe-cies, reporting their morphological comparison, as well as molecular and phylogenetic relationships. According to the results we describe the females of three tick species new to science, i.e., I. nipponrhinolophi Hornok & Takano, sp. nov., I. fuliginosus Hornok & Takano, sp. nov., and I. fujitai Hornok & Takano, sp. nov. In case of all three new tick species the cytochrome c oxidase subunit (coxI) gene showed remarkably high sequence differences from the species that they previously were thought to belong to, well exceed-ing the average limit delineating ixodid tick species. This, as well as observed morphological differences fully justify their taxonomical status as new species.

GPS Based Navigation and Mobile Base Station of a Mobile Robot Platform
Publication Name: Chemical Engineering Transactions
Publication Date: 2023-01-01
Volume: 107
Issue: Unknown
Page Range: 385-390
Description:
One of the central challenges of today is to increase the degree of automation of the available systems and equipment in a sustainable way. This paper presents the development of an outdoor mobile robot platform navigation method, including an on-board unit and a mobile base station to support the operation of the ZalaZone Automotive Proving Ground in Zalaegerszeg, Hungary, by precise, automated deployment of traffic cones. Currently, traffic cone handling is a time- and labor-intensive job. Its automation saves a significant amount of human resources. As a first step, the technical requirements of the problem have been defined. Then, the navigation system that met the pre-defined requirements has been implemented. This paper presents the detailed development of this navigation system, including a description of the test phases as well. As part of the development process, the operation of a Global Navigation Satellite System (GNSS) receiver corrected by Real-Time Kinematic (RTK) is presented, supported by a small, low-power mobile base station, followed by a description of the applied hardware and software components, alongside with the alignment and further development of these components to achieve centimeter-accurate positioning. The Network Transport of Radio Technical Commission for Maritime Services (RTCM) via Internet Protocol (NTRIP) server facilitates the communication between the onboard unit and the base station via a 5G network. This work is continued by a detailed description of the autopilot system on the robotic platform, including the tools and software used for this purpose. The calibration process of the navigation system is described as well. Finally, the results and observations gained during the test are summarized and analyzed. These results have shown that the addition of an RTK system has highly increased the accuracy of a general GNSS receiver. In addition, these results underline the crucial role of 5G networks in the case of automated mobile applications.

Trust and communication in the context of leaders and employees
Publication Name: Journal of International Studies
Publication Date: 2023-01-01
Volume: 16
Issue: 3
Page Range: 159-174
Description:
The article deals with the topic of communication and trust in leadership which affect the success of cooperation and organizational performance. The paper summarizes the theoretical basis of trust and communication and examines what leaders must do to develop them and achieve the expected results and outcomes. The study focuses on Zenger and Folkman’s model related to the two aspects of leaders’ qualities: warmth and professional competence. The empirical analysis is conducted on a dataset obtained from a Hungarian nationwide omnibus study where 999 responses were collected. The methodology is based on the application of Confirmatory Factor Analysis and Binary Logistic Regression. The research confirmed that trust and communication are significant factors of leadership success, whereas warmth is measured to have twice as much importance as professional competence in building the former two. This is the first study where the Zenger and Folkman’s model is controlled in a Central and Eastern European country in the context of leaders and employees.
