Published: July 2021

Abstract

Background: In order to counter and control the spread of the new COVID-19 pandemic, at the beginning of March 2020, the Romanian government decided to apply strict isolation and quarantine measures. Objective: In the present study, we aimed to analyze the impact of the COVID-19 pandemic and isolation/quarantine at home on lifestyle and daily diet, and to identify changes caused by the pandemic related to the nutritional status and food preferences of the Romanian population. Material and Method: We conducted a prospective observational study based on a structured questionnaire that included 30 items for investigating multiple aspects regarding the dietary habits in the context of the pandemic, quarantine and social isolation imposed by the new SARS-CoV-2 coronavirus. The questionnaire was disseminated on various online platforms accessible from any device with an internet connection in Romania, on social media groups between January and March 2021. The questionnaire was made online, using the Google Forms platform, this method being very useful for carrying out the proposed evaluation, as it facilitated the national dissemination of the evaluation questionnaire. The final study group consisted of 620 respondents from 35 counties of Romania. Results: Regarding weight status, we found that the respondents showed significantly more frequent weight fluctuations during the pandemic than before (p <0.0001). The results showed an increase in the mean weight of the respondents during the pandemic vs. their mean weight before (p = 0.04). In contrast, there were no statistically significant differences between the BMI calculated before and during the pandemic (p = 0.3). Respondents, who had a chaotic diet (40.64%) before the pandemic, became significantly more organized in this regard during the pandemic (35.96%) (p = 0.008). Conclusions: We can state that the pandemic period and isolation at home analyzed in terms of eating habits had positive consequences for about half of the study participants which adopted an organized, diversified eating behavior and balanced lifestyle.

Published: July 2021

Abstract
The purpose of this paper is to provide the Mi-8/17 helicopter Structural Health Monitoring (SHM) System Preliminary System Safety Hazard Analysis (PSSHA). The PSSHA identifies and classifies potential hazards, and the actions necessary to reduce or eliminate the risks resulting from the installation and operation of SHM System on board of the helicopter. The overall objective of the PSSHA is to establish that the potential Mi 8/17 helicopter modification does not introduce unacceptable hazard conditions to both the helicopter and personnel. The MIL-STD-882 risk assessment methodology is applied to assess hazards and risk acceptance levels for both hardware and software elements of the SHM system.

Diagnostics of Turbine Blades, Based on Estimation of Frequency Response Function
Authors: Kotkowski Jerzy , Rokicki Edward , Lindstedt Paweł , Spychała Jarosław , Perczyński Jerzy , Karbowiak Hieronim 
Published: July 2021

Abstract
The aim of the study is to propose a diagnostics method based on blade’s vibration model in frequency domain. Amplitude spectrum A(ω) and phase spectrum φ(ω) have been experimentally identified which define transfer function G(jω) = P(ω) + jQ(ω) and their real P(ω) and imaginary Q(ω) parts. Transfer function G(jω) and resulting frequency, amplitude, phase characteristics and real P(ω) and imaginary Q(ω) parts are parts of blade’s diagnostics model. Changes in those characteristics are directly related to changes in the technical condition of the blades. It has been noticed that small changes in the technical condition cause large changes in frequency characteristics, which proves their usefulness in the diagnosis process.

Authors: Kowaleczko Grzegorz , Grajewski Krzysztof , Kobiela Szymon , Kaźmierczak Romuald 
Published: July 2021

Abstract
The paper provides the simulation results of a small-diameter guided training bomb released during atmospheric turbulence. The simulation utilized a guided bombed devised at ITWL. Aerodynamic characteristics of the bomb were obtained from wind tunnel tests and from calculations made by the PRODAS programme. The simulation programme was developed based on a mathematical model describing a spatial motion of an aerial bomb moving in atmospheric turbulence. To describe a turbulence component, the model of stochastic processes proposed by Shinozuki was used. The manuscript includes examples of diagrams of basic parameters showing the bomb flight in a disturbed atmosphere. The analysis of the impact of the standard deviation of the wind on the change in the parameters of bomb flight was performed. The relationships between the parameters of bomb flight and the possibility to hit the target were provided.

Published: July 2021

Abstract
In sailplane aviation, I attach great importance to the achieved aerodynamic parameters due to the main idea of sailplane flights, which is the flight of a sailplane without external energy supply for staying in the air and only in favourable weather conditions, e.g. increasing thermal movements of the air. Only during take-off, external devices, such as a winch or a towing plane, can be used. Therefore, the use of a propulsion installed in sailplanes and operating only during take-off is a very convenient solution. This is a step towards facilitating the access to flying for a wider group of people due to the reduction of costs related to the take-off processes, and also increases the level of safety of sailplane flights by enabling the use of propulsion at critical moments of the flight. The study presents the current trends in the development of gliding, in particular motor gliders. Additionally, as a result of research works, the energy storage system was shown, which is the weakest element of the system, and at the same time the one with the greatest development potential.

Authors: Karaś Rafał 
Published: July 2021

Abstract
The Author of the article proves that in practice the suitable result concerning the balanced development and the effective use of resources should be controlled simultaneously. The setting of the parameters of thermal isolation for constructional products such as light partitions and glazing (windows and doors) with respect to technological development of products is not enough. Production, the product and its transport makes the whole arrangement of processes that influence the entirety resulting from ecology, transport and the effective use of resources. The only way to meet the demands of the strategy described in the EU documents is to implement such product design that assumes for example the optimal transport possibilities.

Abstract
Education for Sustainable Development (ESD) is increasingly embedded in higher education (HE) due to the current emphasis on tackling the environmental crisis. Similarly, Civic Society Organisations are expanding their mobilization and practical action in communities. These approaches can reach almost all people on the planet and open avenues for effective global action around sustainable development. It is important to connect both learners and develop agents of change in society. In this paper, we focus on how digital resources can support democratization of knowledge production and improve equitable citizen participation in ESD and practical action at the local and global levels.
The paper investigates structures, processes and components that support transnational collaboration in digital spaces, particularly, around the enhancement of sustainable environmental attitudes. We use Collaborative Online International Learning (COIL) as a basis to develop EcoCOIL as a versatile model for expanding coalition building tools and principles, to promote environmental citizenship and develop multi-layered communities of practice. Stakeholders include university students and staff, technical experts, business leaders and entrepreneurs, social innovators, policy makers, Community Social Organisations (CSOs), etc. EcoCOIL focuses on co-created wisdom sharing across intercultural, intergenerational and transdisciplinary actors; it brings an innovative, participatory angle to curriculum development by integration of lifelong learning principles and practical facilitation of sustainable behavior within communities in real time.
What Does Education for Sustainable Development Offer in Initial Teacher Training? A Systematic Review
Authors: Pegalajar-Palomino Ma del Carmen , Burgos-García Antonio , Martinez-Valdivia Estefania 
Published: July 2021

Abstract
Promoting Education for Sustainable Development (ESD) in higher education implies an improvement and quality in the exercise of responsible citizenship, being the key in the training of future teachers as the main agent of change and transition towards sustainability in society. The aim of this study is to collect and analyze scientific evidence on the attitudes, competences and training of future teachers towards ESD. Therefore, a qualitative methodology has been carried out based on a systematic review of the most important scientific databases (WoS and Scopus). One of the most interesting results shows that there are favorable attitudes of our education students towards sustainability and their commitment to the environment. However, we can conclude that, in the training of our teachers, there is a deficit in the development of professional skills needed to implement ESD (teaching practice) to contribute to social welfare.

Abstract
Higher education is given increasing recognition by national governments and international agencies throughout the world to become a crucial incentive for sustainable development goals. In the national development of intellectual force at present, the Vietnam policy of education and training, which is of great importance, is the decisive factor for the economic growth and social development as set out by the government. Therefore, the educational development is the responsibility of both the government and the society. It is now clear that the academic staff in higher education institutions is the core force, playing a decisive role in ensuring the quality of higher education as in the case of the International University – Vietnam National University Ho Chi Minh City. The paper investigated the research studies by the university academic staff through their annual publications and the number of lecturers with Doctoral degrees and professorship. The results showed their research studies contributed to the development of the institution in particular, and at the same time predicted how much the stakeholders benefited from this in general. This study may contribute to developing the quality of higher education institutions regarding the promotion of international publications by the higher education faculties.
Chemiosemiosis and Complex Patterned Signals: A Chemosemiotic Hypothesis of Language Evolution
Authors: Lewis Amelia 
Published: July 2021

Abstract
Olfaction, as a semiotic modality, receives relatively less attention than other sensory modalities. However, chemiosemiosis and semiochemicals are fundamental components of zoosemiosis, occurring across animal taxonomic groups. Indeed, olfaction is thought to be one of the most ancient sensory modalities from an evolutionary perspective and significantly, even unicellular organisms, such as the bacterium Escherichia coli, utilize a form of chemiosemiosis when foraging for nutrients, as part of a process known as ‘chemotaxis’. Further, many taxonomic groups have evolved to produce dedicated ‘semiochemicals’ (often known as pheromones or allomones) which have the sole purpose of being diffused into the environment as a social signal. In this paper, I highlight the importance of Umwelt theory when studying animal communication, by reviewing the less conspicuous and intuitive chemiosemiotic modality, across animal taxa. I then go on to discuss chemiosemiosis within a linguistic framework and argue that complex pattern recognition underpins linguistic theory. Thus, I explore the concept that chemiosemiosis has features in common with language, when the factor of time, in the transmission and decoding of a signal, is taken into account. Moreover, I provide discursive evidence in support of a unified theory of sensory perception, based on structural and functional aspects of signal transmission and cognitive complex pattern recognition. I conclude by proposing a chemosemiotic hypothesis of language evolution.
Rats, Mice and Humans
Authors: Delahaye Pauline 
Published: July 2021

Abstract
This paper will introduce the results of a study conducted in 2019 about how humans perceive species they have to live with, despite not wanting to do so—liminal species—, specifically rats and mice. The results presented here are part of a wider study about rats and mice in cities, their relationship with humans, the nuisances they generate as well as the various and important roles they play in the urban ecosystem, introduced at the Gatherings in BIosemiotics 2020.
The study originally focused solely on rats, which are in a difficult societal context in France, especially in Paris: due to heat waves, planned works and floods, rats are becoming more and more present on the surface, instead of being invisible underground as they used to be. However, some of the results suggest that a significant number of participants are not completely positive about being able to distinguish between a rat and a mouse. In order to present a more precise and detailed overview, it was decided to study the difference not only between the cohabitation issues humans may have with actual rats and/or mice, but also between the semiotic relationships that humans have with the symbolic rat and symbolic mouse. As such, this paper will present the results for both species, with their similarities and divergences.
It shows that a significant part of nuisances and cohabitation issues are more “believed” than factual. The paper focuses on how the cultural and emotional backgrounds of participants influence their semiotic relationship with these species, and how the perceived nuisances, threats or issues can vary according to these parameters.
This study aims to develop a better understanding of the different elements that play a part in issues of cohabitation between humans—especially urban humans—and liminal species—especially rodents. It will show how some of the nuisances can be addressed, not by coercive methods on the actual animals, such as extermination, repellents or removal, but through semiotic work and education on the symbolic animal, its related myths, superstitions, fears and phobias.
Imitation as Mechanism for Mimicry
Authors: Jarosek Stephen 
Published: July 2021

Abstract
The neo-Darwinian paradigm is unable to account for the resilient, complex forms that evolve in nature and persist across time. Random mutations do not explain the occurrence of organisms that mimic complex forms in often astonishing detail. In the absence of God as creator, or random mutations as the basis for adaptive traits, there is something else going on. The case that I present in this article is that the only possible mechanism for mimicry in nature is imitation.
Metaphors to Survive by: Mimicry as Biometaphors, Embodiment of Sign and Cognitive Tools (not only) in Animals?
Authors: Bohát Róbert 
Published: July 2021

Abstract
Can Cognitive Metaphor Theory (CMT) be applied productively to the study of mimicry in zoosemiotics and ethology? In this theoretical comparison of selected case studies, I would like to propose that biological mimicry is a type of biosemiotic metaphor. At least two major parallels between cognitive metaphors in human cognition and mimicry among animals justify viewing the two phenomena as isomorphic. First—from the semiotic point of view—the argument is that both metaphor and mimicry are cases of semiotic transfer (etymologically: metaphor) of the identity / sign of the source onto the perceived identity / sign of the target. This identity transfer, in turn, triggers appropriate changes in the response (behavior) of the surrounding (human or animal) interpreters (e.g. predators). Semiotically, the mimicry turns the body of its bearer into a sign of something else, resulting in the interpreters’ (e.g. predators’) perception of species X as species Y—hence, a type of embodied sign and cognitive metaphor. Second, ecologically, a species occupying one niche (e.g. a moth: non-venomous, herbivorous primary consumer) is perceived and identified as an occupant of a different niche (e.g. a hornet: venomous, omnivorous predator). Thus, a potential predator’s Umwelt is affected by its perceiving a hornet moth as “a hornet” where there is, in fact, a moth, and its response to this stimulus will not be predation but avoidance. In terms of CMT, we could call this a biosemiotic metaphor (bio-metaphor), e.g. “A MOTH IS A HORNET” or “PREY IS A PREDATOR”. Further correspondences between mimicry and metaphor include the fact that this bio-metaphorical identification by mimicry does not typically require a “perfect” resemblance between the source and the target sign (or species); this seems to correspond to the prototype categorization in CMT where categories are “open-ended” and only a partial similarity is sufficient for metaphorical identification (compare Lakoff, Johnson 1980; Rosch 1983). Such an identification of mimicry as metaphor could be based on Prodi’s argument that “hermeneutics is not a late product of culture, but the same elementary movement of life that is born because something obscurely interprets something else” (Eco 2018: 350; Kull 2018, 352—364). Inasmuch as animal Umwelten are interconnected inter alia by this natural hermeneutics, the trans-disciplinary approach to the study eco-zoosemiotic interpretants on the basis of metaphor-mimicry isomorphism could open new opportunities in comparative studies of semiosis in human and animal cognition and interactions.

Abstract
The aim of the study was to identify the isolation rate of thermotolerant campylobacters in a small-scale broiler-meat production farm over a one-year period. The second deliverable of the study was to determine the potential virulence markers. The laboratory investigation was performed on 283 samples (cloacal swabs, caeca, carcass swabs) collected on three sampling points (farm, slaughter line, and cold storage). The isolates obtained with the conventional microbiological method were confirmed with multiplex PCR for identification of campylobacters. The presence of 10 virulence genes was analyzed in the C. jejuni isolates (flaA, racR, virB11, dnaJ, wlaN, cadF, ciaB, cdtA, cdtB, cdtC). Out of 283 samples, 169 (59.7%) were confirmed as Campylobacter spp., 111 (39.2%) C. jejuni, and 43 (15.2%) C. coli. C. jejuni was the most prevalent in all sampling points. Campylobacter spp. showed a characteristically seasonal prevalence with the highest isolation rate during the warmer period of the year. We detected the cadF and ciaB genes in all C. jejuni isolates. The flaA gene was present in 50% of the examined strains. The cdt genes (cdtA, cdtB, and cdtC) were confirmed in 52.8%, 52.8%, and 47.2% of the C. jejuni strains, respectively. C. jejuni showed 15 profiles of virulence patterns with four predominant profiles.
