Authors: SAĞAR Mehmet Enes , ÖZÇELİK Tuğba
Published: March 2023

The aim of this research is to examine adolescents' perceptions of the concept of social media through metaphors. The study group of the research consisted of 182 high school students studying in the Aegean Region of Turkey in the 2023-2024 academic year. In the research, a questionnaire consisting of two parts prepared by the researchers was used as a data collection tool. The first part of this form included questions about demographic information (gender, age, school, class, etc.). In the second part, “Social media is like … because …” were asked to complete the statement. The data obtained from the research were evaluated by content analysis, one of the qualitative research methods. In the study, 93 metaphors related to the concept of social media were obtained from adolescents. It was determined that the most frequently used metaphors were “book”, “water”, “cigarette”, “teacher”, “chocolate” and “life” metaphors. The created metaphors are divided into conceptual categories and themes. As a result of the positive category, the themes of happiness, need and useful were reached. As a result of the negative category, addiction, time wasting and harmful themes were obtained. In addition, when we look at the content of the meanings that adolescents attribute to social media, it was concluded that 53.28% of them ascribed a positive meaning to the concept of social media, and 31.31% attributed a negative meaning to social media.

In northern and central Europe road verges offer alternative habitats for declining plant and invertebrate species of semi-natural grasslands. The quality of road verges as habitats depends on several factors, of which the mowing regime is one of the easiest to modify. In this study we compared the Lepidoptera communities on road verges that underwent three different mowing regimes regarding the timing and intensity of mowing; mowing in mid-summer, mowing in late summer, and partial mowing (a narrow strip next to the road). A total of 12,174 individuals and 107 species of Lepidoptera were recorded. The mid-summer mown verges had lower species richness and abundance of butterflies and lower species richness and diversity of diurnal moths compared to the late summer and partially mown verges. By delaying the annual mowing until late summer or promoting mosaic-like mowing regimes, such as partial mowing, the quality of road verges as habitats for butterflies and diurnal moths can be improved.

As Diretrizes Curriculares Nacionais para a Educação Profissional Técnica de Nível Médio - DCNEPTNM - recomendam que o projeto político-pedagógico das instituições e as práticas docentes sejam desenvolvidas a partir de uma “Metodologia da Problematização”. No entanto, o documento não detalha estas recomendações. Neste sentido, este artigo apresenta os resultados de uma pesquisa exploratória que analisou e relacionou concepções sobre a expressão “Metodologia da Problematização” nas próprias DCNEPTNM, em uma amostra da literatura nacional e em um Plano de Curso desenvolvido em uma instituição pública. Este estudo possibilitou a identificação de duas referências principais para a discussão do tema no país, que poderiam oferecer maiores subsídios para o desenvolvimento de práticas fundamentadas em uma “Metodologia da Problematização”. Embora a análise do Plano de Curso, como um exemplo de documento orientador, aponte que esta expressão não está presente, como pode ocorrer em muitos outros planos, alguns princípios e objetivos que a compõem podem ser identificados, mesmo sem referência direta às DCNEPTNM. Em resumo, este artigo busca oferecer uma sistematização das principais bases teórico-metodológicas do tema e chamar atenção para a importância de uma concepção e de uma metodologia problematizadoras nas práticas de Educação Profissional Técnica de Nível Médio, em uma realidade cada vez mais complexa.

Published: March 2023

As a result of the confinement due to the global pandemic of covid-19, teachers and students found themselves in the inevitable situation of suddenly moving from the traditional face-toface model to virtual environments, with the demand for new digital skills and computer resources. The purpose of this scientific article was to describe the digital teaching competence, the main problems that the educational community faced to join virtual environments, as well as the proposals that originated to perform expeditiously in this new modality. The research was based on a systematic review of scientific articles on digital teaching competence in virtual environments in the context of the pandemic, in the Scopus database, with the support of Redalyc, Scielo, Dialnet, Elsevier and Google Scholar. The results show that the digital teaching competence still does not present an optimal level, so the most recurring solution proposal is the training and development of the digital teaching competence. Since to date the direction followed by the actors involved in virtual learning is uncertain, this investigation culminates by proposing an alternative solution.

Authors: Maslii Iryna
Published: March 2023

The study examined the technology of keeping bees in order to increase the activity of hygienic behavior as a factor of natural resistance. The aim of the work was to study the activity of hygienic behavior by determining differences in bees of different breeds, zoned on the territory of Ukraine, in different families of the same breed in different apiaries, healthy and with signs of infectious diseases, as well as studying the specificity of the behavior of adult bees in cleaning the body from parasites (mites Varroa) and recognition and removal of infectioned pupae from brood cells. There was presented the correlation of the activity of hygienic behavior on the breed characteristics and strength of the bee colony. It was determined that the Ukrainian steppe breed of bees had a demonstrative activity of hygienic behavior and was more resistant to infection by ectoparasites and pathogens compared to the Carpathian breed. The difference in the duration of complete cleaning of the cells in bee colonies of the Ukrainian steppe and Carpathian breeds was 4±1 hours on average. There was explored the study of the hygienic behavior of honey bees before the recognition and removal of infectioned pupae from the sealed working brood within the same breed. Bee activity lasted for 6 days, the intensity was maximum in the first three days: on average, 64,5% of damaged pupae were removed. However, the reactions of bees were nonspecific in relation to the parasite. After 6 days no significant differences were found between mechanically damaged cells (47,7%) and cells infectioned by the Varroa mite (48.3%).
The activity of bees was manifested during six days, the intensity of grooming and hygienic behavior was maximum during the first three days: on average, 77,4% of Varroa females were thrown from the bees' bodies and 64.5% of damaged pupae were removed from the cells. However, the reactions of the bees were not specific to the parasite, the corresponding cleaning movements were performed by the bees in the control experiments as well.

One of the problems of modern poultry farming is the shortage of litter materials. In this regard, the practice of litter regeneration and its repeated use is becoming more and more widespread. Regenerated litterwith proper disinfection is safe for the bird and does not negatively affect its growth index as evidenced by research on broiler chickens. At the same time, it has not been studied enough the possibility of using regenerated litter in the rearing and housing of other species and production groups of poultry with a technological cycle much longer than that of broiler chickens. Based on this, the goal of our research was to evaluate the microclimate in the poultry house, welfare and zootechnical indicators replacement young turkeyswhen reared on regenerated litter. There were formed two groups of turkey poults (females) of line 5 of the domestic cross Kharkiv, each with 150 heads in each group, one of which from 6 to 20 weeks of age was grown on a new litter (pine shavings), the other (experimental) on regenerated litter based on the same material. Litter regeneration was performed according to the previously developed technology. The remaining conditions for growing turkey poults of both groups met the regulatory requirements and were similar. It was established that from the 6th to the 12th week of rearing the moisture content of regenerated litter was 11.3-6.6% higher than of new litter (p<0.05). However, during further rearing, the difference in their moisture content became insignificant. At the end of the rearing period, the general condition of the litter in both variantshad no significant differences according to the criteria of moisture, flowability, and clumping. Rearing young turkeys on regenerated litter there was observed an increase of 5.8-1.1 times (p<0.05) in the content of ammonia and 1.5-1.1 times (p<0.05) of carbon dioxide in the air of the house,compared to growing them on new litter. At the same time, their total concentration in the air did not exceed the maximum permissible during any of the rearing periods. Growing young turkeys on regenerated litter did not negatively affect the state of plumage, soles of paws and knee joints of young turkey, as well as their zootechnical indicators.

Published: March 2023

The influence of the calving season on milk production was determined to be 0.9% for 305 days of lactation on average across all farms. In loose-housing, the influence of the season was smaller (0.4%) compared to stall housing (1.6-5.5%). Seasonal differences in the milk output of first calving cows for stall housing was equal to 437-816 kg, and for loose-housing 192-283 kg (р<0.05). In some farms animals of autumn and winter calving were distinguished by the best milk output, while in other farms spring-winter calving cows were more productive. It indicates a significant influence on the production of first-borns by the conditions of housing. The analysis of the indices of lactation constancy according to I. Johansen and A. Hanson indicates that the smallest decrease in milk output in the period of the next 14 weeks of lactation compared to the first 14 weeks of lactation was characterized by the first-borns of the experimental farm "Kutuzivka", and the largest by the animals of the experimental farm "Gontarivka". According to H. Turner's index, the differences between the peak monthly milk output and the milk output per lactation were the smallest in the first calving cows of the experimental farm "Stepne".
Lactation curves of the cows that calved in the autumn-winter period had a steady character, which gradually decreased at maximum productivity for 3-4 months of lactation. In the first 3 months of lactation their herdmates of spring-summer calving also had an increase in milk output which fell dramatically in the following months when the animals were conveyed to winter-stall housing and a decrease in the completeness of feeding cows during this period. According to variance analysis, differences in daily milk output for each of the ten months of lactation were possible (p<0.001).
The highest peak of daily output in all farms was obtained from first calving cows of spring calving which explained by the best conditions of housing and feeding during the calving period. Seasonal differences in the peak daily milk output of first calving cows ranged from 2.0 to 2.5 kg for stall housing and from 1.2 to 1.4 kg for loose-housing (p<0.001).

The formation of comprehensive knowledge of the assessment of physical and technical parameters of sheep wool depending on sex and genotype is one of the problems of animal biology, which is due to the requirements of the theory and practice of sheep breeding, as well as the wool processing industry, although the production of an increasing number of synthetic and artificial fibers. Actually obligatory evaluation of physical and technical parameters of wool is regulated by the current state standards and instructions on conducting breeding work, which determines productivity of selection in relation to further improvement of sheep breeds. However, the available information in the prevailing majority of literature sources on the quality of wool concerns sheep of meat-wool and wool-meat direction of productivity. As for sheep of meat production, in particular the newly created domestic breeds such materials are almost absent which determines the relevance of the work done.
The foregoing article presents the results of the laboratory evaluation of differences in quality indicators of wool of the Dnieper beef sheep breed in relation to their sex and genotype. The research objects are young ewes, heeders, ewes and tupping rams. The experiments have been conducted in the conditions of the analytical laboratory for evaluation of wool quality and the breeding center for sheep breeding of the Institute of animal sciences NAAS. The obtained data indicate that young ewes of the line 024/063 (Ml) have a larger length of wool on the compared topographic areas of the fleece, such as on the back (by 23-69%), maw (by 25-30%), thigh (by 2,5-4,6%). The larger length of wool on maw is characteristic of ewes and tupping rams of this line. The sheep of all sex and age groups, which belonged to the line 024/063 (Ml) are reported to be characterized with the highest wool alignment by length within the evaluated topographic areas of the fleece. In spite of the mentioned differences in the indicator of wool fineness, the examinee sheep of these groups are quite homogeneous. The wool fineness in the groups of ewes and young ewes is within the range of 58-60 quality assortments, while the wool fineness of the replacement heeders and the tupping rams is within the range of 56-60 quality assortments.

Published: March 2023

The study of the genetic structure of the cow population of the Ukrainian Black-and-White dairy breed were carried out in loci of beta-casein (CSN2) and kappa-casein (CSN3) loci, and the distribution of haplotype frequencies was analyzed. The polymorphism of the experimental loci was determined using AS-PCR (allele-specific PCR) in the case of CSN2 and PCR-RFLP (restriction analysis) in the case of CSN3. The frequencies of genotypes and alleles, the value of observable (Ho) and expected (He) heterozygosity, the Wright fixation index (Fis) and the effective number of alleles (ne) were determined based on the results of the studies. Haplotype frequencies were determined by calculating the EM-algorithm using the EH+ program. Calculations of the standardized measure of deviation by linkage from the equilibrium state were made using the 2LD program. According to the results of the studies, polymorphism was revealed for both experimental loci in the cattle population of the Ukrainian Black-and-White dairy breed. At the CSN2 locus, the A1 allele frequency was 0.44; A2 – 0.56. At the CSN3 locus, the A allele frequency was 0.80; allele B – 0.20. The experimental cattle population was in a state of genetic equilibrium in accordance with both polymorphic loci. Based on the analysis of the haplotype frequencies distribution, haplotype CSN2A1-CSN3A was found to have the highest frequency (0,46), haplotype CSN2A2-CSN3B had the smallest (0,085). In the experimental cattle population of the Ukrainian Black-and-White dairy breed there is no deviation from the equilibrium state by linkage (D′ = 0.33; which is significantly less than the critical value) between the identified allelic variants of the CSN2 and CSN3 loci. This indicates that the distribution of haplotype frequencies is the result of the particularities of the corresponding alleles frequency distribution.

Authors: Park Sieun , Park Sookyoung
Published: March 2023

Objective: This study aimed to investigate whether the sleep quality is associated with body composition, selective attention, and autonomic nervous system (ANS) activity in healthy young individuals.Methods: This cross-sectional study was conducted using the Korean version of Pittsburgh Sleep Quality Index (PSQI-K). Sixteen healthy volunteers aged 20–26 years participated in this study. The PSQI-K was used to evaluate sleep quality, and they were divided into good and poor sleeper groups by PSQI-K. Body composition, and both reaction time and error number for discriminative reaction task indicating the selective attention, and ANS activity were measured and it compared according to sleep quality. Additionally, the correlation between sleep quality and ANS activity was analyzed.Results: There were no significant differences in the body composition, reaction time and error number between good and poor sleeper groups. In the ANS activity, the poor sleeper group only showed the lower HF value than the good sleeper group in resting state (p=0.023). Whereas, the amount of change (reaction task state – resting state) in mean HR (p=0.005), HF (p=0.039), and LF/HF ratio (p=0.023) were significantly different between the groups. Additionally, a negative correlation was observed between PSQI-K and HF (p=0.005), while a positive correlation was confirmed between PSQIK and LF/HF ratio (p=0.012).Conclusion: These findings indicate that even healthy individuals may have physiological problems such as ANS imbalance if the sleep quality is poor.

Authors: Park Kyung mee , Kyong Taeyoung
Published: March 2023

Sleep and circadian disturbance are common in hospitalized patients. Problems related to sleep induction, frequent awakening, poor sleep quality, and disturbed circadian rhythm including daytime somnolence and nighttime arousal are frequently observed in the hospital. Disturbance of sleep and circadian rhythm could interfere recovery of the patients, prolong the length of stay, and contribute to patient dissatisfaction. Various factors affect sleep and circadian rhythm disturbance in the hospital. Intrinsic factors are related to patients, including medical and psychiatric conditions, uncontrolled pain, prescribed medications, and physical inactivity. External factors related to the hospital environment such as noisy environment, excessive exposure to artificial light, inappropriate humidity, and temperature are also known interrupters for sleep. Medical care provided by professionals, including nighttime vital sign monitoring, phlebotomy, and medication administration, can also contribute to sleep and circadian rhythm disturbances. This review aims to systematically address sleep and circadian rhythm disturbances in hospitalized patients, discuss factors that affect sleep in the hospital, and suggest non-pharmacological and pharmacological treatment options.

The growth of the tourism sector depends on tourism investment in small and medium-sized businesses throughout various regions. This paper investigates the impacts of capital, expectations of benefits, knowledge, and information on residents' investment decisions in the tourism industry. Investment in tourism is a key driver of economic expansion and development. So, it is necessary to look into locals' predisposition to invest in the tourism industry. A suitable process for selecting study participants was used, and the questionnaire method was used to collect data. Partial least square structural equation modelling was then used to evaluate the data (PLS-SEM). The findings of this study indicate that citizens' investment decisions are influenced by capital, knowledge, information, and benefit expectations. The results of this study will provide policymakers and the management of Malaysian tourist industry with new information that they can use to create successful regulations that encourage locals to make investment decisions that will advance the tourism industry.

Published: March 2023

Objective: This research was conducted to determine the relationships between psychological well-being, social support, and work-life balance and the mediating effect of psychological well-being on the relationship between social support and work-life balance. Methods: Data were collected from a convenience sample of 277 participants. Data analysis was done with regression and the Pearson correlation coefficient. Regression-based mediation analysis developed by Hayes (2013) was used to examine the mediation effect of psychological well-being. Results: Work-life balance is negatively related to social support (r=-.51) and, positively related to psychological well-being (r=.50). As a result of the mediation analysis based on regression to determine the mediating effects, it was concluded that psychological well-being had a mediating effect on the relationship between social support and work-life balance. The bootstrapp (10000) method was used to determine whether the mediation analysis was significant. Conclusions: These findings suggest that the inverse relationship between social support and work-life balance is at least partly explained by the level of psychological well-being.

Detecting Covid-19 and Other Lung Diseases with Deep Learning
Authors: Tembo Yamikani , Mweshi George
Published: March 2023

Since December 2019, Covid-19, also known as severe acute respiratory syndrome (SARSCOV-2), has infected about 531 million individuals worldwide causing devastating consequences. Scientists, health professionals, and radiologists have all invested huge amounts of time, effort and resources in developing faster and accurate methods for detecting the virus as it spreads all over the world. The current gold standards for detecting covid-19 such as RT-PCR, POC, Droplet-based digital PCR (dPCR) and Immunoassays are not only expensive for low-income countries but also require substantial human expert knowledge which in turn makes them time-consuming and susceptible to manipulation. The study presented in this paper aims to address these issues by proposing a model to automatically detect COVID-19 in chest X-rays using Deep Learning techniques. Specifically, the model uses convolutional neural networks (CNNs), a deep learning technique, which has been shown to produced very good results when applied to medical image diagnosis problems. Our proposed model will therefore not only provide a cheaper, faster and accurate method of detecting COVID-19 but will also provide an easy to use web and mobile platform for non-experts. While current detection techniques such the RT-PCR are still considered as the most effective, our CNN-based model was also able to produce good results when applied to the COVID-19 radiography dataset. For instance, the model was able to detect COVID-19 from X-ray images with an accuracy rate of 90 percent. Furthermore, the model was also able to automatically detect other respiratory diseases such as viral pneumonia and lung opacity with an accuracy rate of over 90 percent. Given the potential of the automated detection of COVID-19 established in this study, future work will extend this work by incorporating automated search techniques such as genetic algorithms in the fine tuning of the model’s parameters in order to obtain an even higher accuracy rate.

Forecasting of election results is one of the key activities prior to elections. In Zambia, like many other countries, opinion polls have been used to predict the outcome of elections since 1999. During the run up to the 2021 general elections, two opinion polls were conducted. One poll suggested that HH would emerge victorious whilst the other predicted that ECL would emerge victorious. Actual results announced on the 16th of August 2021 by the Electoral Commission of Zambia (ECZ) had HH  obtaining 59.02% of the votes. The variance in the two opinion polls leaves room for alternative approaches to predicting election results. This study proposes sentiment analysis as part of the initial stage to building an alternative solution to predicting the outcome of an election. The study analysed sentiments shared on social media during the build up to the August 2021 general elections. A total of 3,519 tweets were scrapped from Twitter and sentiment analysis was performed on the tweets. Topic modeling was subsequently also performed on the tweets using BERTopic. The findings of the study reveal that as election day drew closer, there was an exponential increase in the number that were posted on a daily basis. Some of the topics included voter engagement and education, the shutdown of the internet and the election day.
A Privacy-Preserving Scheme for Medical Diagnosis Records Based on Encrypted Image Steganography

Healthcare diagnosis records are essential as they establish perpetual reports on the health of patients. These records are in nature meant to be kept confidential. It is for this reason that medical data should be secured before transmission. Steganography and cryptography are old concepts used to secure communications. Steganography is hiding data into a carrier, for instance, images, videos, texts, and files. It seeks to hide the existence of communications. Cryptography is communication in deciphering secret writings or ciphers. In our privacy-preserving scheme for healthcare records, a hybrid approach is used to ensure the maximum multi-level security of medical records before transmission. The proposed system utilizes AES-128 which is a symmetric key encryption algorithm to scramble the data. As compared to asymmetric key encryption, symmetric key encryption is faster as only one key is used for both encryption and decryption. To resolve the problem of key distribution that plagues symmetric cryptosystems, the proposed system makes use of the Diffie-Hellman key exchange algorithm for key agreement. In this way, the encryption essentials are securely exchanged before the actual transmission of the date. To ensure efficient and optimal steganography throughput, the Least significant bit (LSB) which involves the hiding of information in the most repetitive bits of each pixel of an image was implemented for steganography. The technique was chosen because the level of distortion made to the image is low hence the image quality change is minimal. As such, the resultant robust system, is highly impeccable, utilises efficient compression, and has improved capacity which are all desirable features for securing medical health records.

An investigation was carried out on fish market infrastructure of Khulna district to identify the infrastructure facilities of domestic fish market including species traded along with price and also to detect the constraints at different levels of trading recommending possible solutions according to standards. The investigation was conducted from November 2016 to June 2017 in three different markets of Khulna district namely Sandhya Bazar fish market, Aranghata Bypass Bazar fish market and Baikali Bazar fish market. In Khulna, a large number of people are involved in fish marketing. Market infrastructures of Khulna had grown up according to various influencing factors that controls the total system involved. The study was based on observation and field survey. Data were collected through eye observation, questionnaire interviews and focus group discussions. Several number of market agents including wholesalers, retailers were selected for questionnaire interviews and aratdars and fishermen were selected for focused group discussions. It was revealed that the infrastructure facilities were inadequate and poorly maintained. Fish sheds were not enough hygienic to protect the fish from contamination. Surface water drainage system was open and this situation degraded further environmental condition of the markets. Electricity maintenance was not up to the mark and there were no distillation process for the supplied water. This infrastructural condition does not support a hygienic condition for fish marketing to provide edible and quality fish. Total number of freshwater fish species traded in different markets was found 60 including 12 SIS, 34 culture and 14 capture. On the other hand 41 brackish and marine water species were found and 14 crustacean species of which 5 were freshwater prawn, 6 brackish water shrimp and 3 crabs. Therefore domestic market infrastructure is on a developing stage as being controlled by Khulna City Corporation (KCC). Establishment of ice factory, improvement of fish transport facilities, introduction of fish quality control measures were suggested to improve the fish marketing in the study area.

Salinity is a major limiting factor reducing crop yields in coastal areas of Bangladesh. The main objective of this study was to mitigate the adverse effects of soil salinity on wheat by organic and inorganic amendments. The field experiment was conducted at BRRI station, Sonagazi, Feni. Wheat cv. BARI Gom-23 was used as a test crop. There were thirteen treatment combinations consisting of control, farmyard manure (FYM) (5 t ha-1), FYM (10 t ha-1), compost (10 t ha-1), compost (20 t ha-1), gypsum (50% GR), gypsum (100% GR), K2SO4 (100 kg ha-1), K2SO4 (200 kg ha-1), FYM (5 t ha-1) + gypsum (50% GR), FYM (5 t ha-1) + K2SO4 (100 kg ha-1), compost (10 t ha-1) + gypsum (50% GR), compost (10 t ha-1) + K2SO4 (100 kg ha-1). FYM and compost were added to the soils during final land preparation. Gypsum and sulphate of potash were applied in two splits as per treatments. Nitrogen, phosphorous, zinc and boron fertilizers were applied as basal doses. The experiments were laid out in a randomized complete block design with three replications. Soil salinity caused a reduction in growth and yield of wheat. Soil amendments with organic or inorganic fertilizers improved growth and yield of wheat under soil salinity. Combined application of organic and inorganic fertilizers showed higher yields of wheat than that of alone during salinity conditions. Both organic and inorganic fertilizers increased nutrient uptake and K+/Na+ ratio in wheat during salinity condition. Therefore, the present study suggests that wheat production might be feasible in coastal areas of southern Bangladesh through organic and inorganic amendments of saline soils.
