Learning from climate change news: Is the world on the same page?
Authors: Eikelboom Stijn , Esteve-Del-Valle Marc , Nissim Malvina
Published: March 2024

Climate change challenges countries around the world, and news media are key to the public’s awareness and perception of it. But how are news media approaching climate change across countries? With the problem of climate change and its solution being global, it is key to determine whether differences in climate change news reports exist and what they are across countries. This study employs supervised machine learning to uncover topical and terminological differences between newspaper articles on climate change. An original dataset of climate change articles is presented, originating from 7 newspapers and 3 countries across the world, and published in English during 26 Conference of the Parties (COP) meetings from the United Nations Framework Convention on Climate Change (UNFCC). Three aspects are used to discriminate between articles, being (1) countries, (2) political orientations, and (3) COP meetings. Our results reveal differences with regard to how newspaper articles approach climate change globally. Specifically, climate change-related terminology of left-oriented newspapers is more prevalent compared to their right-oriented counterparts. Also, over the years, newspapers’ climate change-related terminology has evolved to convey a greater sense of urgency.

Over the past two decades, increasing numbers of humpback whales have been returning to feed in the inshore waters of British Columbia (BC) where marine aquaculture farms are situated. This has led to growing concerns that the presence of aquaculture farms may pose an entanglement threat to humpback whales. However, it is not known whether aquaculture facilities attract humpback whales, or whether there are factors that increase the likelihood of humpback whale, becoming entangled and dying. We examined eight reports of humpback whales interacting with Atlantic salmon farms in BC from 2008 to 2021 to evaluate the conditions that may have contributed to their entanglements. Of the eight entangled humpbacks, three individuals died and five were successfully disentangled and released. All were young animals (1 calf, 7 subadults). Multiple factors were associated with two or more of the reported incidents. These included facility design, environmental features, seasonality, humpback whale age, and feeding behaviour. We found that humpback whales were most commonly entrapped in the predator nets of the aquaculture facilities (6/8 incidents), and were less often entangled in anchor support lines (2/8). The presence of salmon smolts did not appear to be an attractant for humpback whales given that half of the reported entanglements (4/8) occurred at fallowed salmon farms. Almost all of the entanglements (7/8) occurred in late winter (prior to the seasonal return of humpbacks) and during late fall (after most humpbacks have migrated south). Overall, the number of humpback whales impacted by fish farms was small compared to the numbers that return to BC (> 7,000) and accounted for <6% of all types of reported entanglements in BC. Human intervention was required to release humpback whales at fish farms, which points to the need to have well-established protocols to minimize entanglements and maximize successful releases.
CO2 and CH4 dynamics in a eutrophic tropical Andean reservoir

Published: March 2024

We studied the dynamics of methane (CH4) and carbon dioxide (CO2) in a eutrophic tropical reservoir located in the Colombian Andes. Temporal and spatial dynamics were addressed through sampling during six field campaigns conducted throughout a two-year period. We monitored fluxes at the air-water interface, dissolved gas concentrations, physical and chemical properties of the water column, microstructure profiles of turbulence, and meteorological conditions. Throughout the study period, the reservoir was a persistent source of CH4 to the atmosphere with higher emissions occurring in the near inflow region. During periods of low water levels, both the emissions and surface concentrations of CH4 were higher and more spatially heterogeneous. The measured CO2 fluxes at the air-water interface changed direction depending on the time and location, showing alternating uptake and emissions by the water surface. Mass balances of dissolved CH4 in the surface mixed layer revealed that biochemical reactions and gas evasion were the most significant processes influencing the dynamics of dissolved CH4, and provided new evidence of possible oxic methane production. Our results also suggest that surface CH4 concentrations are higher under more eutrophic conditions, which varied both spatially and temporally.

Introduction

There have been numerous studies that showed the presence of human papillomavirus (HPV) in breast cancer; nonetheless, there is ongoing debate regarding their association. Given few studies in Ethiopia, we aimed to investigate the magnitude of HPV infection in Ethiopian breast cancer patients.

Methods

A total of 120 formalin-fixed paraffin-embedded (FFPE) tissue blocks were obtained, and basic demographic, clinical, and histological data were collected from medical records. DNA was extracted from archived FFPE breast tissue specimens using GeneRead DNA FFPE Kit. The AnyplexTM II HPV28 Detection Kit (Seegene, Korea) was used to detect HPV by following the manufacturer’s instructions. The SPSS Version 25 was used to enter and analyze data.

Results

Among the 120 study participants; HPV (both high-risk and low-risk) was detected in 20.6% of breast cancer and 29.6% of non-malignant breast tumors. The most common genotype was the high-risk HPV 16 genotype. The frequency of HPV was nearly 10-fold higher in estrogen receptor-positive than ER-negative breast cancer. The percentage of HPV in the luminal (luminal A and luminal B) breast cancer subtypes was also much higher than in the non-luminal subtypes (HER-2 enriched and triple-negative breast cancer).

Conclusion

This study did not find a significant difference in HPV expression between breast cancer and non-malignant breast tumors; however, the higher percentage of HPV in ER-positive compared to ER-negative breast cancer warrants further attention.
Gender differences in the effects of emotion induction on intertemporal decision-making
Authors: Fiorenzato Eleonora , Bisiacchi Patrizia , Cona Giorgia
Published: March 2024

‘Good things come to those who wait’ is a popular saying, which goes along with numerous daily life decisions requiring trade-offs between immediate-small and later-larger rewards; however, some individuals have a tendency to prefer sooner rewards while discounting the value of delayed rewards, known as delay discounting. The extant literature indicates that emotions and gender can modulate intertemporal choices, but their interplay remains hitherto poorly investigated. Here, 308 participants were randomized to different conditions, inducing distinct emotions–fear, joy, a neutral state–through standardized movie clips, and then completed a computerized delay discounting task for hypothetical money rewards. Following the induction of fear, women discount the future steeper than men, thus preferring immediate-smaller rewards rather than larger-delayed ones. Also, women were more prone to choose immediate rewards when in a fearful condition than when in a positive state of joy/happiness. By contrast, men were unaffected by their emotional state when deciding on monetary rewards. Our findings provide evidence that fear can trigger different intertemporal choices according to gender, possibly reflecting the adoption of different evolutionary strategies.

Recent findings suggest that stigma and camouflaging contribute to mental health difficulties for autistic individuals, however, this evidence is largely based on UK samples. While studies have shown cross-cultural differences in levels of autism-related stigma, it is unclear whether camouflaging and mental health difficulties vary across cultures. Hence, the current study had two aims: (1) to determine whether significant relationships between autism acceptance, camouflaging, and mental health difficulties replicate in a cross-cultural sample of autistic adults, and (2) to compare these variables across cultures. To fulfil these aims, 306 autistic adults from eight countries (Australia, Belgium, Canada, Japan, New Zealand, South Africa, the United Kingdom, and the United States) completed a series of online questionnaires. We found that external acceptance and personal acceptance were associated with lower levels of depression but not camouflaging or stress. Higher camouflaging was associated with elevated levels of depression, anxiety, and stress. Significant differences were found across countries in external acceptance, personal acceptance, depression, anxiety, and stress, even after controlling for relevant covariates. Levels of camouflaging also differed across countries however this effect became non-significant after controlling for the covariates. These findings have significant implications, identifying priority regions for anti-stigma interventions, and highlighting countries where greater support for mental health difficulties is needed.

Published: March 2024

Hypertension is a widely prevalent disease and uncontrolled hypertension predisposes affected individuals to severe adverse effects. Though the importance of controlling hypertension is clear, the multitude of therapeutic regimens and patient factors that affect the success of blood pressure control makes it difficult to predict the likelihood to predict whether a patient’s blood pressure will be controlled. This project endeavors to investigate whether machine learning can accurately predict the control of a patient’s hypertension within 12 months of a clinical encounter. To build the machine learning model, a retrospective review of the electronic medical records of 350,008 patients 18 years of age and older between January 1, 2015 and June 1, 2022 was performed to form model training and testing cohorts. The data included in the model included medication combinations, patient laboratory values, vital sign measurements, comorbidities, healthcare encounters, and demographic information. The mean age of the patient population was 65.6 years with 161,283 (46.1%) men and 275,001 (78.6%) white. A sliding time window of data was used to both prohibit data leakage from training sets to test sets and to maximize model performance. This sliding window resulted in using the study data to create 287 predictive models each using 2 years of training data and one week of testing data for a total study duration of five and a half years. Model performance was combined across all models. The primary outcome, prediction of blood pressure control within 12 months demonstrated an area under the curve of 0.76 (95% confidence interval; 0.75–0.76), sensitivity of 61.52% (61.0–62.03%), specificity of 75.69% (75.25–76.13%), positive predictive value of 67.75% (67.51–67.99%), and negative predictive value of 70.49% (70.32–70.66%). An AUC of 0.756 is considered to be moderately good for machine learning models. While the accuracy of this model is promising, it is impossible to state with certainty the clinical relevancy of any clinical support ML model without deploying it in a clinical setting and studying its impact on health outcomes. By also incorporating uncertainty analysis for every prediction, the authors believe that this approach offers the best-known solution to predicting hypertension control and that machine learning may be able to improve the accuracy of hypertension control predictions using patient information already available in the electronic health record. This method can serve as a foundation with further research to strengthen the model accuracy and to help determine clinical relevance.
Characteristics of cervicovaginal microflora at different cervical maturity during late pregnancy: A nested case-control study
Authors: Chen Ping , Hu Tingting , Zheng Zheng , E. Garfield Robert , Yang Jinying
Published: March 2024

Objective

The mechanism of cervical ripening in late pregnancy is still unclear. The vaginal microbiome has been reported to correlate with the preterm birth and short cervix in pregnant women. However, the associations between the cervical maturity and the vaginal microbiome are still poorly understood. We aim to analyze the cervicovaginal microflora in women with ripe cervix and in those who are unripe when delivering at term.

Methods

Cervicovaginal swabs were collected between 40 and 41 weeks of gestation from the following 2 different groups of patients: ripe group (n = 25) and unripe group (n = 25). Samples were tested using 16S ribosomal RNA gene high-throughput sequencing and analyzed by bioinformatics platform.

Results

This study highlights the relationship between cervical maturity during late pregnancy and the composition of the cervicovaginal microflora. Both α- and β-diversity analyses demonstrated significant differences between women with a ripe cervix and those with an unripe cervix. Notably, the Lactobacillus profile was found to be closely linked to cervical maturity. There was a significant difference in the vaginal community state type, with CST IV being more prevalent in women with an unripe cervix. Furthermore, the association between CST IV and the unripe cervix group, as indicated by the odds ratio of 8.6, underscores its relevance in evaluating cervical maturity, when compared to other Lactobacillus-dominant community state types. Additionally, several bacterial taxa, particularly Lactobacillus, exhibited differential relative abundances between the two groups.

Conclusion

This study provided significant evidence regarding the relationship between the vaginal microbiome and cervical maturity, highlighting the differential diversity, community state types, and specific bacterial taxa, such as Lactobacillus, that are associated with cervical maturation status. These findings contributed to our understanding of the dynamics of the cervicovaginal microflora during late pregnancy and its implications for cervical health.

Published: March 2024

We studied spatial variation in seagrass communities in the Andaman and Nicobar archipelago (ANI), India using latitude as a surrogate variable. We classified the ANI into five latitudinally distinct island groups: North & Middle Andaman, Ritchie’s archipelago, South Andaman, Little Andaman, and the Nicobar archipelago. We evaluated the Importance Value Index (IVI) for species to determine the ecologically dominant seagrasses within each Island group. Later, we related our findings to investigate the three decadal pre- and post-tsunami status of seagrass habitats in the ANI which were severely impacted by the Indian Ocean tsunami of 2004. Six of the 11 observed species, such as Halophila ovalis, Halophila beccarii, Halophila minor, Halodule pinifolia, Thalassia hemprichii, and Cymodocea rotundata, dominated the seagrass population among all island groups. Seagrass composition significantly varied across the five investigated latitudinal gradients. Seagrass communities in ’Ritchie’s Archipelago and Nicobar’ and ’South Andaman and Little Andaman’ revealed the highest and lowest variation. Further, Ritchie’s Archipelago and Nicobar had the highest species richness (n = 10), followed by North & Middle Andaman (n = 8), and the lowest in South and Little Andaman (n = 6). Despite similar species richness and composition, Nicobar contributed to the highest seagrass coverage compared to the lowest recorded in the Ritchie’s Archipelago. Our observations on the re-colonization of disturbed areas by early successional and historical species suggest recovery of the seagrass population in the ANI post-disturbance. Lastly, co-variates associated with latitude as a surrogate warrant further investigation.

Background and Aim: Fertility is crucial for enhancing the efficiency of livestock production, as it directly impacts the reproductive rates. A comprehensive understanding of the relationship between sperm quality and embryo development is key to optimizing reproductive outcomes and improving the quality of livestock. This study analyzed the developmental competence of in vitro embryos recovered from Bali cattle with normal or poor sperm motility.

Materials and Methods: Nine bulls with normal fresh semen (NFS) or poor fresh semen (PFS) motility were ejaculated for semen. Semen ejaculates, including volume, motility, and sperm concentration, were evaluated immediately after collection to measure the quality of the fresh semen. Frozen semen was evaluated using computer-assisted semen analysis (CASA) for motility, progressive sperm motility, distance curve path, distance curve linear, distance straight line, average path velocity, curvilinear velocity, linear velocity, straightness (STR), linearity of forward progression (LIN), wobble, and average lateral head displacement (ALH). Bull groups were used to determine in vitro embryo cleavage ability after fertilization of Bali cattle. Ovaries of Bali cattle were collected by slicing, and only cytoplasmic oocytes with compact cumulus cells were used in this study. The oocytes were matured, and in vitro fertilization was performed using fertilization media with a final sperm concentration of 1.5 Ã— 106 spermatozoa/mL. After 48 h, the embryo cleavage ability of the cultured oocytes was evaluated.

Results: There were significant differences in motility values between the NFS and PFS groups; however, there were no significant differences in the volume or sperm concentration. There was a significant difference in the LIN value between the groups but no significant differences in other CASA parameters. There were no significant differences in the cleavage rate and morula between the groups, but a positive correlation was observed between the cleavage rate and the morula and between the morula and ALH. A significant negative correlation was observed between the cleavage rate and STR and between the morula and STR; no significant differences were observed for other variables.

Conclusion: Despite variations in sperm characteristics, both normal and poor sperm motility demonstrated comparable in vitro embryonic development competence. These findings provide important insights into the fertility potential of Bali bulls, providing valuable information that can enhance selection strategies to improve the quality of livestock production.

Keywords: Bali cattle, embryos, in vitro semen quality.

Published: March 2024

This paper aimed to empirically validate a multidimensional measurement model for the Nature-Based Tourism Destination Image - NBDI, including the cognitive, affective, and conative components, present in the construct of variables tested by Chaves and Anjos, (2022). The validation of the NBDI measurement model relied on a non-probability quota-based sample consisting of 592 international tourists who visited the Legal Amazon destination. The results pointed out that the NBDI can be measured by a three-dimensional construct of 3rd Order, where the image components presented a positive influence in the formation of the overall image, being the affective component of greater influence, followed by the cognitive and conative, presenting convergent and discriminant validity. The study contributes to the theoretical discussions about NBDI, offering a multidimensional scale with reliable psychometric property and validated with 57 variables, scarce subjects in the scientific literature, as well as, in the marketing strategies of public and private institutions.
Functions of Word Play in a Comedy Television Show (Based on Good Omens TV series)
Authors: Nukhov Salavat , Voytsekh Ksenia
Published: March 2024

Despite the great interest of scientists in word play, this phenomenon is still insufficiently studied. Many researchers highlight the comic function as the basis for word play. In this study, word play is viewed as the intentional use of a non-standard language code in order to express the inner world of the speaker, which is not always associated with the creation of a comic effect. The subject of this research deals with cases of language play in the Good Omens comedy series. Film discourse can be interpreted as a reflection of the current state of culture and the society, as well as of the language, which became a decisive factor in the choice of research material. The author of the article comes to the conclusion that the comic function does not play a key role in the use of word play in a comedy television series, being exceeded in frequency by such functions as characterological, meaning-forming and expressive. The article contains numerous material from a modern television series, which gives one the ground to realize the relevance of the conclusions.

Peculiarities of Semantic and Word-Formation Development of the Lexical Unit пилот
Authors: Dudurich Olga
Published: March 2024

The article describes the mechanism of the developing of a new meaning of the lexeme пилот in the Russian language. It is proved that the new lexico-semantic variant "experimental, trial" initially arises in the semantic structure of the word pilot in English. Its transition into Russian, however, is not a process of mechanical calquing, but an active process of adaptation of the lexeme in the recipient language. Morphological peculiarities of Russian language determine the introduction of the new meaning in three different forms: the noun пилот, the adjectival phrase пилотный проект and the analytical structure пилот-проект. The neosemantism пилот forms the derivatives пилотировать and пилотаж with the meaning "to manage pilot projects". The adjective пилотный is actively used as an attribute with nouns denoting subjects of testing. The development of semantics introduces into the meaning of the adjective the seme of ʽinnovativenessʼ, which is absent in the donor language.
Verbal and Nonverbal Ways of Presenting Information in School Discourse (Linguo-Semiotic Aspect)
Authors: Victoria Chernova
Published: March 2024

The article covers the study of verbal, non-verbal and mixed type presentemes in the context of school discourse. The text of the lesson is presented as a semiotic heterogeneous discourse. Our research contains the material of particular teachers’ lesson plans from Catherine Gymnasium 36 in Krasnodar. The methodological basis of the study is a need-based information approach to phenomena of school communication which allows to define modes of coexistence of visual presentemes with verbal components of a lesson.  The results of the study led to conclusion that school discourse has special features, which make it possible to distinguish it as a particular type of institutional discourse. The presence of verbal, non-verbal and mixed type presentisms in it proves that the lesson is a semiotic heterogeneous text. The impact on the pupil is one of the teacher’s speech functions, which is realized more effectively if the verbal level of communication is accompanied by a non-verbal component.

Published: March 2024

Gas-liquid bioreactors in which the introduction of the gas substrate in the culture liquid is carried out from the vortex cavity formed by the rotation of the stirrer.  In order to simplify the design and intensify mass transfer a new method of dispersing the gas substrate from the vortex cavity is proposed and studied.  It consists in maintaining local zones with reduced pressure in the liquid behind the rotating paddles and creating the necessary conditions for the introduction of the gas substrate. On the basis of numerical simulation the pressure is calculated and the zones of low pressure in liquid behind the stirrer paddles are determined. The value of differential pressure necessary for gas dispersion has been estimated. The angular velocity of liquid rotation depending on the number of partitions on the apparatus wall and the number of mixer revolutions is presented. The gas content in the liquid during the implementation of the investigated method has been determined. The average surface diameter of gas bubbles and interfacial surface of gas-liquid medium were calculated from experimental data. The power spent on stirring in the apparatus has been established and the power criterion with regard to gas content has been determined. Mass transfer at intensive gas dispersion from gas vortex cavity into liquid has been investigated. Criterion dependence for calculation of mass transfer coefficient is presented, taking into account energy dissipation spent on mixing and interfacial surface. The fields of application of bioreactor with new method of gas dispersion are shown.

Authors: Krasner Y. A. , Romanov V. V. , Fazullina O. N. , Osipenko M. F. , Klimontov V. V.
Published: March 2024

BACKGROUND: The diagnosis of liver fibrosis is an important task in the management of patients with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes. The currently used diagnostic methods have a number of disadvantages such as invasiveness and high cost, or insufficient sensitivity and specificity. Therefore, the search for new non-invasive markers of liver fibrosis remains an actual challenge.

AIM: To assess a diagnostic value of serum growth differentiation factor-15 (GDF-15), microfibril-associated glycoprotein 4 (MFAP-4), collagen type IV alpha1 (COL4alpha1), Mac-2 binding protein (M2BPGI) and chitinase-3-like protein 1 (YKL-40) as markers of liver fibrosis in patients with type 2 diabetes and NAFLD.

MATERIALS AND METHODS: A single center cross-sectional observational study was performed. The study included 74 patients, 23 men and 51 women, aged 18 to 74 years. Liver elastography was used as reference method for the fibrosis evaluation. APRI and fib-4, non-invasive fibrosis indices, were assessed. Serum concentrations of GDF-15, MFAP-4, COL4alpha1, M2BPGI, and YKL-40 were determined by ELISA. ROC analysis was used to evaluate the sensitivity and specificity of serum markers for the diagnosis of the liver fibrosis.

RESULTS: Liver fibrosis stage 1 was verified in 16 subjects, stage 2 in 12, stage 3 in 7, and stage 4 in 19. Patients with advanced liver fibrosis (stages 3–4), compared with those without severe fibrosis (stages 0–2), had higher levels of GDF-15 (p=0.003), COL4alpha1 (p=0.007), and YKL-40 (p=0.04). Patients with stage 1-2 liver fibrosis had higher levels of COL4alpha compared to those without any signs of fibrosis (p=0.02). There were no significant differences in the level of MFAP-4 and M2BPGI between patients with different severity of fibrosis. According to the ROC analysis, GDF-15, COL4alpha1 and YKL-40 have diagnostic value in the detection of severe liver fibrosis comparable to that of the APRI and fib-4 indices.

CONCLUSION: GDF-15, COL4alpha1 and YKL-40 could be considered as promising non-invasive markers of liver fibrosis in patients with type 2 diabetes and NAFLD.

Published: March 2024

O presente estudo teve o objetivo de analisar a gestão da cadeia de suprimentos de um marketplace de orgânicos através dos fatores chave de desempenho, associando aos benefícios para o escoamento de alimentos para os pequenos produtores rurais. Utilizando um estudo de caso, recorreu-se à teoria de gestão de cadeia de suprimentos e seus fatores-chave de desempenho para fundamentar a análise das informações levantadas. A pesquisa focou em uma empresa que intermedia a distribuição de frutas, legumes e verduras orgânicos no estado do Espírito Santo, com atenção especial ao galpão e aos produtores que atuam exclusivamente no município de Santa Maria de Jetibá. Dos resultados obtidos, ao examinar o estoque, transporte, instalação e informação, observou-se que a empresa possui uma estrutura para contornar a falta de tecnologia no campo, acompanhando todo o ciclo de produção, alertando o cliente sobre potenciais quebras de fornecimento e orientando o produtor sobre o processo de comercialização, como o padrão de qualidade exigido. Portanto, concluiu-se também que, apesar de apresentar vantagens, caso a empresa passe por um período de crescimento, será necessário um ajuste das políticas de estoque e uma atenção maior na gestão de contratos e fornecedores.

Published: March 2024

The activities of preparing and issuing Forensic Science Services reports are a public service of great importance for society and for the executive and judicial branches. However, notably, it has difficulties in meeting due dates, causing damage to all involved and generating additional costs for governments. In practice, it is observed that knowledge in the area of operations management is not used to determine the allocations of Forensic Science services at Criminalistics Technical Sections. Therefore, the objective of this research is to develop and apply knowledge related to the operations scheduling of Forensic Science reports. To fulfill the objective, the case study research method was applied in the Regional Technical Section of Criminalistics (STRC) of Três Corações - Minas Gerais in Brazil. Real data from that Forensic Unity carried out in the past were implemented in an APS (Advanced Planning and Scheduling) software and new allocations, based on the software's internal algorithms, were carried out. The results of allocations from the software have been compared with the previous results. The comparisons show that scheduling from the software's algorithms can bring better results.
GENDER CONSTRUCTION IN FAMILY REALITY: A CASE STUDY OF THE ROLE OF POST DIVORCE FAMILY INTERACTIONS IN INDONESIA
Authors: Dewi Kartika Sari , Ginanjar Adriana , Nugroho Fentiny , Anggita Devina
Published: March 2024

The purpose of this study was to highlight the dynamics of gender construction in divorced families. This study used a  qualitative method with a case study design on eight mothers-youths from divorced families. In contrast to previous research, this study identified the role of post-divorce family interactions in the construction of gender associated with their well-being. The study’s findings show that the gender scheme developed by youth is linked to patterns of interaction in the family after the parents’ divorce. Changes in parent roles and the presence of extended families contribute to their gender construction. There is an evaluation process that builds an understanding of dynamic gender roles in the family in order to understand the reality of the post-divorce family. Fathers who re-opened communication with their children, mothers as gatekeepers in communication and parenting, and mothers’ and children’s perceptions of the extended family all contributed to the evaluation process. Youth from divorced families face challenges in seeking well-being. They still believe that an intact family is ideal and that the presence of a responsible father is considered important for young people, while the presence of an extended family causes dilemmas in family interactions.

Published: March 2024

La pandemia por COVID-19 ha generado diversos problemas de salud mental en la población, puesto que las rutinas fueron afectadas abruptamente y la población se vio obligada a aislarse de sus familiares y amigos, y a cambiar la modalidad de sus trabajos, especialmente durante el tiempo en el cual las medidas fueron más restrictivas. Todo ello ha derivado en problemas de ansiedad, depresión, estrés y riesgo de suicidio, entre otros. El objetivo de este estudio fue conocer el riesgo de afectación en salud mental entre personas que reportaron malestar psicológico durante el aislamiento por COVID-19 en una muestra de 396 adultos jóvenes en Colombia. Este es un estudio retrospectivo, que siguió un diseño caso-control, para identificar la influencia del malestar psicológico percibido, el cual se evaluó a través de autorreporte. Los instrumentos utilizados fueron: a) un cuestionario de datos sociodemográficos, b) Depression, Anxiety and Stress Scale (DASS-21), (c) Overall Depression Severity and Impairment Scale (ODSIS), d) Overall Anxiety Severity and Impairment Scale (OASIS), e) Escala de Zung para Ansiedad, f) Escala de Riesgo Suicida de Plutchik. Los resultados muestran que el riesgo de padecer afectación en salud mental es al menos dos veces mayor en quienes percibieron malestar psicológico durante el aislamiento restrictivo en comparación con aquellos que reportaron no tener el mismo malestar (OR(estrés) = 2.04; OR(riesgo suicidio) = 2.61; OR(ansiedad) = 2.85; OR(depresión) = 3.37). La depresión es la variable de salud mental de mayor impacto, pues el riesgo de tener sintomatología depresiva es tres veces mayor; sin embargo, en la triada depresión-ansiedad-estrés es aún más alto el riesgo de afectación en quienes estuvieron expuestos al malestar psicológico (OR = 3.71). Estos hallazgos evidencian la necesidad de intervención en salud mental, especialmente en quienes tienen más de una afectación.

Las redes sociales virtuales atraen a diferentes usuarios por las múltiples potencialidades e impactos característicos de esta sociedad tecnológica. El propósito de este estudio es identificar las redes sociales virtuales más usadas por los jóvenes, los motivos personales de uso y la relación de su utilización con la percepción de soledad y las habilidades de autoexpresión en escenarios sociales. En particular, se evalúan las diferencias de tales usos en función de la edad, el nivel de escolaridad y el género. En el estudio participaron 251 jóvenes adultos españoles con edades comprendidas entre los 18 y 40 años (X = 26.33, D.T. = 5.91) contactados a través de un muestreo no probabilístico por conveniencia. Se observó que el uso de las redes sociales virtuales se ve aumentado en los participantes con bajas habilidades sociales, altos niveles de soledad y más jóvenes. Destacan los motivos de aburrimiento y evasión o escape para usar los espacios digitales y se registra una tendencia en los jóvenes de la generación Z (18 a 28 años) a utilizar más las redes sociales virtuales, en comparación con los de la generación Y (29 a 40 años). Como conclusiones, se señala la conveniencia de controlar el uso problemático de las redes sociales virtuales y de entrenar las habilidades sociales para mejorar las relaciones interpersonales.
Standard of protection of property rights of owners of residential premises in a democratic country – selected problems considered in the light of Polish constitutional law
Authors: Pisz Maciej
Published: March 2024

The article focuses on presenting key issues revealed in the context of the standard of protection of property rights of owners of residential premises in a contemporary democratic state governed by the rule of law. The considerations presented take into account the perspective of Polish constitutional law and the guarantees of protection of ownership and other property rights as regulated in the Constitution of the Republic of Poland of April 2, 1997 (with particular emphasis on Article 21 and Article 64). The issue addressed in this paper of particular importance from the Polish perspective because, on the one hand, Polish constitutional law formulates relatively broad guarantees for the protection of ownership and other property rights (including those rights of owners of residential premises and tenants – as outlined in Article 21 and Article 64 of the Polish Constitution). On the other hand, there are several practical problems in Poland in this context, including a very significant systemic issue related to the lack of any systemic solutions in the regulation of the short-term rental market by the Polish legislator.

Objectives

Computerized breath sound based diagnostic methods are one of the emerging technologies gaining popularity in terms of detecting respiratory disorders. However, the breath sound signal used in such automated systems used to be too noisy, which affects the quality of the diagnostic interpretations. To address this problem, the proposed work presents the new hybrid approach to reject the noises from breath sound.

Methods

In this method, 80 chronic obstructive pulmonary disease (COPD), 75 asthmatics and 80 normal breath sounds were recorded from the participants of a hospital. Each of these breath sound data were decontaminated using hybrid method of Butterworth band-pass filter, transient artifact reduction algorithm and spectral subtraction algorithm. The study examined the algorithms noise rejection potential over each category of breath sound by estimating the noise rejection performance metrics, i.e., mean absolute error (MAE), mean square error (MSE), peak signal to noise ratio (PSNR), and signal to noise ratio (SNR).

Results

Using this algorithm, the study obtained a high value of SNR of 70 dB and that of PSNR of 72 dB.

Conclusions

The study could definitely a suitable one to suppress noises and to produce noise free breath sound signal.
Physical and mechanical response of porous metals composites with nano-natural additives
Authors: Hassan Zainab Kassim , Kseer Khamaal Mohsin
Published: March 2024

The mechanical and physical characteristics of composites are made of reinforced palm leaves and copper, the green palm leaves in nanoparticles forms once, and another sample from ash powder of palm leaves with copper powder metal as a matrix that was studied. First, a Cu metal was complemented with green palm leaf at a ratio (10:20:30)% on a sub-micron scale and second with the ash of palm leaves with the same ratio (10, 20, and 30)% and as nanoparticles. Apparent porosity, thermal conductivity, SEM, and compressive strength were carried out. It was noticed that adding additives to Cu causes its apparent porosity rise, porosity value of Cu samples supported with green palm leaves fibers was higher than that of Cu samples supported with palm leaves ash, and the highest percent of porosity was for the sample supported with 30% green palm leaves fibers which were 2.4%. It is also clear from the results that the increase in the percentage of additives led to a significant decrease in the thermal conductivity, as it decreased from 385 W/m K for the unsupported copper sample to 175 W/m K for the green copper supported sample, which was the lowest value, while the lowest value recorded for the palm leaves ash supported sample was 253 W/m K. The results of the compression test showed that the inverse relationship between the percentage of additives and the value of the compressive strength, as the lowest value of the compressive strength estimated at 23 MPa was recorded for the copper sample reinforced with 30% green palm leaves, and it is the same sample that recorded the highest value for porosity as mentioned before.
