Furthermore, themethod was census applied to all respondents by interview to obtain primary data on capture fishermen, namely name, age, education, business experience, amount of fuel, catch, fishing time, cost, and bait based on a structured questionnaire. The data obtained is then calculated using the formula for total costs, revenues, and revenues. The fishing process carried out by fishermen with traps and nets is the same, namely the preparation of fishing gear, including engines, boats, fuel, consumption, and bait as well as the selection oflocations fishing ground. The income of bubu fishermen is an average of Rp.4,030,449/month during Covid-19. Meanwhile, the average income of net fishermen is Rp. 3,183,813/month during Covid-19. The production of trap fishermen during Covid-19 remained at 180 kg/month but with increased profits to Rp. 5,429,652. On the other hand, the production of net fishermen has decreased to 120 kg/month with a profit of Rp. 3,204,766 during Covid-19. The thing that causes a decrease in the profits of fishermen catching nets is the reduced amount of production caused by constraints such as torn nets and restrictions on activities by the government. The crab fishermen have increased the selling price of the crab which was originally between Rp.30,000 before Covid-19 to Rp.35,000 during Covid-19.

El uso indiscriminado de sustancias toxicas (agrotóxicos, hormonas, antibióticos y otros) en la producción agrícola, provoca problemas de salud en las personas y en los ecosistemas, ya sea por exposición directa o indirecta. Durante muchos años se ha utilizado estas sustancias en actividades agrícolas, específicamente a gran escala, sin tomar en cuenta el potencial de afección a la salud humana y de los ecosistemas, en la actualidad varios estudios a nivel mundial señalan la presencia de agrotóxicos y sus metabolitos en diferentes matrices ambientales y humanas, por lo que se hace necesario la investigación de estos contaminantes en el agua, suelo, aire, alimentos y personas, aplicando técnicas confiables y seguras, que permitan tomar medidas para evitar la exposición y los posteriores daños en la población, por otro lado la agroecología se presenta como una alternativa para disminuir y evitar el uso de sustancias tóxicas en beneficio de la vida. Los objetivos de este trabajo son Discutir los límites de la agricultura convencional y los daños que este modelo de producción tiene para la salud humana y el ambiente, a través del uso intensivo de agrotóxicos, defender la agricultura agroecológica como alternativa a la producción saludable de alimentos y la importancia de realizar la identificación y cuantificación de los residuos de agrotóxicos en diferentes matrices, como forma de vigilancia de los daños de esas sustancias, contribuyendo para la superación del modelo productivo toxico dependiente.

La salud mental es un estado de bienestar en el cual la persona mantiene consciencia total de sus capacidades/habilidades y sabe cómo utilizarlas para la vida cotidiana, los primeros conceptos de cuidados de enfermería nacen por Philippe Pinel y Hildegard Peplau que mejoran la calidad y calidez frente a la atención de estos pacientes, el objetivo de la investigación es determinar la atención de enfermería en pacientes psiquiátricos y su incidencia en los afectos del personal. El universo fue conformado por 27 personas que laboran en la casa de reposo "Sagrado Corazón de Jesús" de la cuidad de Ambato. Se aplicó una encuesta conformada por 8 preguntas, evaluada con la escala de afecto positivo y afecto negativo de PANAS y puntuada con la escala de Likert. Se obtuvo como resultado que la primera, segunda, tercera, quinta y sexta pregunta predominaron emociones positivas dentro de actividades realizadas durante la atención del paciente, mientras que la cuarta, séptima y octava pregunta fueron encaminadas a buscar las emociones después de la atención, prevaleciendo los afectos negativos. Se concluye que el personal de salud está inmerso en varias situaciones laborales que le producen emociones positivas y negativas, siendo las más peligrosas las emociones negativas ya que impiden un correcto cuidado de los pacientes por lo cual es necesario la implementación de actividades de relajación y terapias con un psicólogo que eduque y ayude al personal a restablecer las emociones afectadas para brindar una mejor atención al paciente y mejorar la salud mental del cuidador.

Published: November 2022

Residence time distribution (RTD) has a very high impact on the performance of a chemical reactor. The development of new reactor and catalyst structures has increased the importance of deep knowledge in theories of RTDs and good experimental practice in measuring RTDs in real systems. Therefore, RTD studies are included in chemical engineering education all over the world. This work demonstrates how RTDs can be measured by using urban pieces of art. Impulse experiments with an inert tracer (NaCl) were conducted in a marvelous modern artwork, ‘Flow of time’ in Turku/Åbo. The results were successfully interpreted with the classical laminar flow model. The application of the methodology in historical university cities is suggested.
Identification of decompensation episodes in chronic heart failure patients based solely on heart sounds
Authors: Susič David , Poglajen Gregor , Gradišek Anton
Published: November 2022

Decompensation episodes in chronic heart failure patients frequently result in unplanned outpatient or emergency room visits or even hospitalizations. Early detection of these episodes in their pre-symptomatic phase would likely enable the clinicians to manage this patient cohort with the appropriate modification of medical therapy which would in turn prevent the development of more severe heart failure decompensation thus avoiding the need for heart failure-related hospitalizations. Currently, heart failure worsening is recognized by the clinicians through characteristic changes of heart failure-related symptoms and signs, including the changes in heart sounds. The latter has proven to be largely unreliable as its interpretation is highly subjective and dependent on the clinicians’ skills and preferences. Previous studies have indicated that the algorithms of artificial intelligence are promising in distinguishing the heart sounds of heart failure patients from those of healthy individuals. In this manuscript, we focus on the analysis of heart sounds of chronic heart failure patients in their decompensated and recompensated phase. The data was recorded on 37 patients using two types of electronic stethoscopes. Using a combination of machine learning approaches, we obtained up to 72% classification accuracy between the two phases, which is better than the accuracy of the interpretation by cardiologists, which reached 50%. Our results demonstrate that machine learning algorithms are promising in improving early detection of heart failure decompensation episodes.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is evident in up to 15% of all acute myocardial infarctions (AMI) and disproportionally affects females. Despite younger age, female predominance, and fewer cardiovascular risk factors, MINOCA patients have a worse prognosis than patients without cardiovascular disease and a similar prognosis compared to patients with MI and obstructive coronary artery disease (CAD). MINOCA is a syndrome with a broad differential diagnosis that includes both ischemic [coronary artery plaque disruption, coronary vasospasm, coronary microvascular dysfunction, spontaneous coronary artery dissection (SCAD), and coronary embolism/thrombosis] and non-ischemic mechanisms (Takotsubo cardiomyopathy, myocarditis, and non-ischemic cardiomyopathy)—the latter called MINOCA mimickers. Therefore, a standardized approach that includes multimodality imaging, such as coronary intravascular imaging, cardiac magnetic resonance, and in selected cases, coronary reactivity testing, including provocation testing for coronary vasospasm, is necessary to determine underlying etiology and direct treatment. Herein, we review the prevalence, characteristics, prognosis, diagnosis, and treatment of MINOCA -a syndrome often overlooked.

This narrative inquiry draws on the longstanding collaborative work of the Portfolio Group (a cross-school, cross-institution teacher/teacher educator/researcher group) to explore the role of collaborative critical friendship in our group’s reflective practice and the influence on our individual growth as teachers/teacher educators/researchers. Narrative methods were employed, aided by a conceptual frame of reflection, critical friendship, and optimal experience. Results and discussion highlight how teacher practice is enhanced and strengthened when teachers come together as critical friends to share stories of experience, to examine experiential currents, undercurrents, and riptides (i.e., plotlines, dilemmas, contexts, interactions, politics, etc.), and to provide meaningful feedback that supports colleagues’ professional growth.

Published: November 2022

Polycystic ovary syndrome (PCOS) affects up to 20% of women but remains poorly understood. It is a heterogeneous condition with many potential comorbidities. This review offers an overview of the dysregulation of the reproductive and metabolic systems associated with PCOS. Review of the literature informed the development of a comprehensive summarizing ‘wiring’ diagram of PCOS-related features. This review provides a justification for each diagram aspect from the relevant academic literature, and explores the interactions between the hypothalamus, ovarian follicles, adipose tissue, reproductive hormones and other organ systems. The diagram will provide an efficient and useful tool for those researching and treating PCOS to understand the current state of knowledge on the complexity and variability of PCOS.

Authors: Zhang Jiayu , Ye Jiawen , Tao Xinge , Lu Wenjing , Chen Xueqin , Liu Changqin
Published: November 2022

Objectives

(1) To establish the prevalence of sleep disorders in women with PCOS. (2) To establish the association between sleep disturbance and cardiovascular risk factors in women with PCOS.

Methods

The electronic databases PubMed and EMBASE were searched for observational studies of individuals with PCOS published in English from inception to 21 October 2021. The dichotomous outcome measure was presented as odds ratio (OR) and 95% confidence interval (CI). The mean difference (MD) in continuous variables was expressed for each study.

Results

A total of 18 articles were included in this meta-analysis, with a total of 16,152 participants from nine different countries. Women with PCOS had a high prevalence of sleep disturbance (OR = 6.22; 95% CI: 2.77, 13.97; p < 0.001), higher PSQI scores (MD = 2.10; 95% CI: 0.29, 3.90; p = 0.02), and shorter duration of sleep (MD = −15.65 min; 95% CI: −27.18, −4.13; p = 0.008). We found that body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), low-density lipoprotein cholesterol (LDL-c), fasting glucose, 2-h glucose, and waist circumference (WC) levels were significantly higher and high-density lipoprotein cholesterol (HDL-c) was significantly lower in PCOS with sleep disturbance than in PCOS without sleep disturbance.

Conclusions

The current study shows a high prevalence of sleep disturbance in women with PCOS and provides evidence of an association between cardiovascular risk factors and sleep disturbance among this population. Increased attention should be paid to sleep management in clinical guidelines for PCOS.

Symmetric and asymmetric nexus between economic policy uncertainty, oil price, and renewable energy consumption in the United States, China, India, Japan, and South Korea: Does technological innovation influence?
Authors: Rong Guo , Qamruzzaman Md
Published: November 2022

This study aimed to gauge the impact of economic policy uncertainty, oil price, and technological innovation on renewable energy consumption in the top five oil-importing nations for the period 1990–2021. The study employed a linear and nonlinear framework in exploring the association and variable elasticities on renewable energy consumption. According to linear assessment, the study documented positive effects from technological innovation and oil price volatility, whereas economic policy uncertainty adversely caused renewable energy integration, especially in the long run. The study disclosed long-run and short-run asymmetric connections between TI, EPU, and REC for asymmetric assessment. For directional causality, the study documented feedback hypothesis that explain the nexus between oil price and renewable energy consumption in China [OIL←→REC]; economic policy uncertainty and renewable energy consumption [EPU←→REC] in China, India, Japan, and South Korea; and technological innovation and renewable energy consumption [TI←→REC] in South Korea. On a policy note, the study established that efficient energy transition from fossil fuel to renewable energy demands economic stability and, therefore, stability must be ensured. Furthermore, oil prices should be considered while formulating energy policies.
Tracing carbon emissions convergence along the way to participate in global value chains: A spatial econometric approach for emerging market countries

Published: November 2022

The proliferation of trade agreements has offered a viable framework for the economic and trade integration of many nations. Additionally, the growth and expansion of global value chains has increased prospects for knowledge and technological spillovers as well as the potential for production method convergence. This might have possible effects on the environment in both developed and developing nations. The objective of this study is to determine whether participation in global value chains (GVCs) can serve as a foundation for the convergence of carbon emission across nations. Spatial panel data econometrics is used to examine data from 22 emerging economies between 1995 and 2019 in order to provide an answer. The findings support the global value chains-based conditional carbon convergence of the countries and show a spatial link between global value chains participation and CO2 growth. Furthermore, results show that increasing global value chains participation with other variables; both directly and indirectly, via spillover effects, encourages closing the CO2 emission gap across nations. The findings show that global value chains may be able to increase how successful carbon efficiency initiatives are. Therefore, when developing environmental legislation, many aspects of global value chains participation and their advantages should be considered.

In a context of multi-crises, as well as the challenges of both the medium and long term, associated with elements highlighted by the transformation of the EU energy system, we appreciate that not only is it a very difficult time to overcome efficiently and balanced EU Member States, but above all it is a time to activate research systems on identifying key solutions, as well as firm decisions at the level of decision-making institutions at the level of the European Institutions. Moreover, based on the latest European studies, systematic testing of ongoing initiatives can strategically prepare for an increase in the resilience of Member States’ economies to crisis shocks, as well as “the key to success Europe’s ecological transformation and climate neutrality of the EU economy in a broader sense.” The paper aims to highlight how to act at European level in the context of the latest energy decisions (regulations, strategies, pro-grams and directives) and how to stimulate “the EU economy with about 3.3% of EU GDP or EUR 464 billion in 2030 and up to EUR 5.6% or more than EUR 1 trillion in 2050.” At the same time, we appreciate that as a result of green energy, digitalization and technology, the environmental objective on the EU and UN net emissions in 2050 can be achieved, especially as a result of a fair and equitable transformation for the economic environment and for citizens, being an objective that directly contributes to achieving a sustainable, collaborative and prosperous society with an open and modern society, but more chosen efficiently in terms of resource optimization and a sustainable and competitive economy.
Testing fiscal burden role on energy transition and economic recovery in South Asian economies
Authors: Guo Li-fang
Published: November 2022

The aim of the study is to test the role of fiscal burden on energy transition and economic recovery. The major emphasis of this study, from this viewpoint, is on the repercussions of fiscal burden on energy transition through net GDP rate in eight different nations including the south Asia region, and to unlock the opportunities for economic recovery. In order to determine whether or not there were any effects of foreign fiscal burden on energy transition through net GDP rate in the data, the World Bank collected data for the period 2000–2018. The study conducted a GMM and quantile regression analysis to see if there were any effects of foreign fiscal burden on energy transition, and how it infers economic recovery. In spite of the facts that international fiscal burden has a considerable negative influence on economic recovery and energy transition. The robustness analysis validates these results, with influencing variables accounting for 39 percent and 31 percent, respectively, with the total external fiscal burden and external fiscal burden service of the total external fiscal burden. The findings of this research will be useful to government authorities in their attempts to design more efficient and effective economic strategies in the foreseeable future. Hence, study suggested the practical implications to reduce fiscal burden and accelerate economic recovery through energy transition.

Meat quality, an important economic trait, is regulated by many factors, especially by genetic factors, including coding genes, miRNAs, and lncRNAs. Recent studies have elucidated that circRNAs also play a key role in muscle development and lipid deposition. However, the functions and regulatory mechanisms of circRNAs in meat quality remain mostly unknown. The circRNA expression profiles between Huainan pigs (Chinese indigenous pigs, fat-type, Huainan HN) and Large White pigs (Western commercial pigs, lean-type, LW) in the longissimus dorsi (LD) muscle at 38, 58, and 78 days post conception (dpc) were compared by sequencing. In total, 39,887 circRNAs were identified in 18 samples, and 60, 78, and 86 differentially expressed circRNAs (DECs) were found at the three stages mentioned above between these two breeds. The parent genes of DECs were enriched in myogenesis, proliferation, adipogenesis and muscle fiber-type transition. The circRNA-miRNA interaction networks included 38 DECs and 47 miRNAs, and these miRNAs were involved in muscle development and lipid metabolism. Two shared DECs (circ_0030593 and circ_0032760) of these three stages were selected, their head-to-tail junction sites were validated by Sanger sequencing, and RT‒qPCR results suggested that these two DECs might be involved in intramuscular fat deposition. These findings provide a basis for understanding the role of circRNAs in meat quality.
