Authors: Teunissen Lauranna , Cuykx Isabelle , Decorte Paulien , Vandebosch Heidi , Matthys Christophe , Pabian Sara , Van Royen Kathleen , De Backer Charlotte
Published: March 2023

This study aims to understand how and why emerging adults come into contact with food media messages, and what they perceive as positive and negative outcomes related to food literacy. Seven focus groups, stratified by gender and socio-economic status, with 37 emerging adults aged between 18 and 25 were conducted. Photovoice was used to reflect on participants’ real-life food media experiences. Findings reveal that food media consumption is a combination of actively searching and incidentally encountering. The results suggest that food media messages attract emerging adults’ attention by bringing content in an entertaining, engaging, and appealing way, and featuring popular food personalities. Finally, food media messages were perceived to both enhance and distort food literacy. The results show how food media messages for food literacy interventions can be designed in order to attract emerging adults’ attention and fulfill their specific needs.
“Home, Sweet Home”: Identity and Diaspora in Bai Jing-rui’s Qiong Yao Films
Authors: Zhou Xuelin
Published: March 2023

This paper discusses the Qiong Yao films directed by Bai Jing-rui in the 1970s, arguing that these romantic dramas took a proactive part in representing a cultural identity in Taiwan society of the time. The paper investigates how various issues, such as “home”, nationhood and diaspora, are treated in the films. In the process, the paper situates the filmic discussion in the wider context of a highly politicised environment in general and the industrial discourses of “healthy realism” and “healthy variety-show” in particular. The paper proposes that Bai Jing-rui’s Qiong Yao films grew out of a push-and-pull between three elements: (1) the authorities that wanted to promote certain moral and political messages; (2) Bai Jing-rui as an auteur strongly committed to the art of filmmaking; and (3) the audience at large whose support was needed to sustain a film industry. The paper gives close attention to how Bai’s Qiong Yao films tried various ways of reconciling those competing forces. As case studies, the paper examines closely two of Bai Jing-rui’s Girl Friend (1975) and Far Away from Home (1977) to show how they blended modernity with nativism in articulating a sense of cultural identity.
Two adjustments of the second levelling of Finland by using nonconventional weights
Authors: Cvetkov Vasil
Published: March 2023

Despite being in use for more than 150 years, the error accumulation in precise levelling has not yet been completely clarified. It is believed that the error accumulation in this method is proportional to the square root of the levelling length. The first goal of this article is to demonstrate that this belief is not always scientifically proven. The second aim is to show that it is likely that a better adjustment decision will be missed if inverse distance weighting with a power parameter equal to one is automatically applied. Using linear regression analysis the measuring data of the Second Levelling of Finland is analysed. An inadequacy of the relationship between the absolute values of the differences between both measurements of the elevations in the levelling lines and their length is shown, which is due to heteroscedasticity. In order to obtain a homoscedastic model, the other two models are constructed. Based on the regression analysis results, the network is adjusted using three types of weights. The adjustment with traditional weights has produced significantly greater mean errors of the nodal benchmarks than both variants based on weights, which are functions of the absolute values of the line elevations.
Measuring the Concept of PID Literacy: User Perceptions and Understanding of PIDs in Support of Open Scholarly Infrastructure
Authors: Macgregor George , Lancho-Barrantes Barbara S. , Pennington Diane Rasmussen
Published: March 2023

The increasing centrality of persistent identifiers (PIDs) to scholarly ecosystems and the contribution they can make to the burgeoning “PID graph” has the potential to transform scholarship. Despite their importance as originators of PID data, little is known about researchers’ awareness and understanding of PIDs, or their efficacy in using them. In this article, we report on the results of an online interactive test designed to elicit exploratory data about researcher awareness and understanding of PIDs. This instrument was designed to explore recognition of PIDs (e.g. Digital Object Identifiers [DOIs], Open Researcher and Contributor IDs [ORCIDs], etc.) and the extent to which researchers correctly apply PIDs within digital scholarly ecosystems, as well as measure researchers’ perceptions of PIDs. Our results reveal irregular patterns of PID understanding and certainty across all participants, though statistically significant disciplinary and academic job role differences were observed in some instances. Uncertainty and confusion were found to exist in relation to dominant schemes such as ORCID and DOIs, even when contextualized within real-world examples. We also show researchers’ perceptions of PIDs to be generally positive but that disciplinary differences can be noted, as well as higher levels of aversion to PIDs in specific use cases and negative perceptions where PIDs are measured on an “activity” semantic dimension. This work therefore contributes to our understanding of scholars’ “PID literacy” and should inform those designing PID-centric scholarly infrastructures that a significant need for training and outreach to active researchers remains necessary.

This is due to the starch has good characteristics which are great biodegradability, low cost and also easy to gain from natural resources. However, some of technical challenges are also introduced before starch-based polymers can be used in more applications. These technical challenges involved preparation methods and incorporation of additives and these are being summarized in this topic. Hence, the enhancement of starch can be done in order to prepare innovative starch-based biodegradable materials.
Translation of surface electromyography to clinical and motor rehabilitation applications: The need for new clinical figures
Authors: Merletti Roberto , Temporiti Federico , Gatti Roberto , Gupta Sanjeev , Sandrini Giorgio , Serrao Mariano
Published: March 2023

Advanced sensors/electrodes and signal processing techniques provide powerful tools to analyze surface electromyographic signals (sEMG) and their features, to decompose sEMG into the constituent motor unit action potential trains, and to identify synergies, neural muscle drive, and EEG–sEMG coherence. However, despite thousands of articles, dozens of textbooks, tutorials, consensus papers, and European and International efforts, the translation of this knowledge into clinical activities and assessment procedures has been very slow, likely because of lack of clinical studies and competent operators in the field. Understanding and using sEMG-based hardware and software tools requires a level of knowledge of signal processing and interpretation concepts that is multidisciplinary and is not provided by most academic curricula in physiotherapy, movement sciences, neurophysiology, rehabilitation, sport, and occupational medicine. The chasm existing between the available knowledge and its clinical applications in this field is discussed as well as the need for new clinical figures. The need for updating the training of physiotherapists, neurophysiology technicians, and clinical technologists is discussed as well as the required competences of trainers and trainees. Indications and examples are suggested and provide a basis for addressing the problem. Two teaching examples are provided in the Supplementary Material.
Metabolomics meets systems immunology
Authors: Fu Jianbo , Zhu Feng , Xu Cheng‐Jian , Li Yang
Published: March 2023

Metabolic processes play a critical role in immune regulation. Metabolomics is the systematic analysis of small molecules (metabolites) in organisms or biological samples, providing an opportunity to comprehensively study interactions between metabolism and immunity in physiology and disease. Integrating metabolomics into systems immunology allows the exploration of the interactions of multilayered features in the biological system and the molecular regulatory mechanism of these features. Here, we provide an overview on recent technological developments of metabolomic applications in immunological research. To begin, two widely used metabolomics approaches are compared: targeted and untargeted metabolomics. Then, we provide a comprehensive overview of the analysis workflow and the computational tools available, including sample preparation, raw spectra data preprocessing, data processing, statistical analysis, and interpretation. Third, we describe how to integrate metabolomics with other omics approaches in immunological studies using available tools. Finally, we discuss new developments in metabolomics and its prospects for immunology research. This review provides guidance to researchers using metabolomics and multiomics in immunity research, thus facilitating the application of systems immunology to disease research.

Published: March 2023

Osteogenesis imperfecta (OI) is a genetically and clinically heterogeneous disorder characterized by bone fragility and reduced bone mass generally caused by defects in type I collagen structure or defects in proteins interacting with collagen processing. We identified a homozygous missense mutation in SEC16B in a child with vertebral fractures, leg bowing, short stature, muscular hypotonia, and bone densitometric and histomorphometric features in keeping with OI with distinct ultrastructural features. In line with the putative function of SEC16B as a regulator of trafficking between the ER and the Golgi complex, we showed that patient fibroblasts accumulated type I procollagen in the ER and exhibited a general trafficking defect at the level of the ER. Consequently, patient fibroblasts exhibited ER stress, enhanced autophagosome formation, and higher levels of apoptosis. Transfection of wild‐type SEC16B into patient cells rescued the collagen trafficking. Mechanistically, we show that the defect is a consequence of reduced SEC16B expression, rather than due to alterations in protein function. These data suggest SEC16B as a recessive candidate gene for OI.
The modern state of femoral, acetabular, and global offsets in total hip arthroplasty: a narrative review
Authors: Luca DiGiovanni Peter , Gasparutto Xavier , Armand Stéphane , Hannouche Didier
Published: March 2023

Offsets in the frontal plane are important for hip function.

Research on total hip arthroplasty (THA) surgery agrees that increasing femoral offset up to 5 mm could improve functional outcome measures.

The literature indicates that global offset is a key parameter that physicians should restore within 5 mm during surgery and avoid decreasing.

Substantiated findings on acetabular offset are lacking despite its recognized importance, and the medialization approach must be assessed in light of its shortcomings.

Future research, possibly through improved measurement, unified definitions, patient-specific surgical planning, and technology-enhanced surgical control, with specific focus on acetabular offset, is needed to better understand its impact on THA outcomes.
TEACHER PROFESSIONAL MOBILITY AS AN INNOVATIVE TREND AND TODAY'S REQUIREMENT
Authors: Chervinska Inna , Prytuliak Oksana , Melnyk Nadiya , Vasylyk Maryna
Published: March 2023

The article is devoted to the theoretical and practical aspects of the problem of professional mobility of the teacher, which is considered by the authors as an innovative trend and an urgent requirement of the modern system of higher education. The authors emphasize that professional mobility can be considered as one of the most essential professional features of a teacher, scientist, and researcher. It is noted that the professional mobility of a teacher is based on pedagogical culture and skills and professional competence. Researchers distinguish the following types of mobility: social, professional, academic, intellectual, socio-cultural, cultural, educational and personal. It is pointed out that the driving forces and motivating factors of professional mobility are usually educational reforms, social innovations, the adoption of a new legal framework, educational concepts, revolutions, wars, rapid development of scientific and technical progress, digitalization of the educational process, structural and institutional changes in the education system of the country, region. It is noted that mobility in the pedagogical field is a special quality of personality that is formed in the process of education and upbringing and has a major impact on the professionalism of a future specialist. The authors indicate that professional mobility means the movement of an individual or a professional group in the socio-professional sphere of society, with or without a change in social status. It is also emphasized that the activity of manifestations of professional mobility is influenced by direct professional training and indicators of its quality, the level of qualification obtained. A high level of professional mobility contributes to the optimization of the educational process in the conditions of rapid aging of knowledge, dynamic development and changes in the market of professions, increasing the dependence of an individual's professional career on the level and quality of the obtained education, on the ability to rebuild and adapt according to social transformations.

THE DEVELOPMENT OF THE HUMANISTIC OUTLOOK OF YOUNGER SCHOOL STUDENTS OF A GENERAL EDUCATION SCHOOL IN EXTRA-SCHOOL ACTIVITIES
Authors: Klepar Maria , Potapchuk Tetyana , Chinchoy Alexander , Nych Oksana
Published: March 2023

In this article, we consider the development of the humanistic worldview of younger schoolchildren in extracurricular activities as a set of basic principles: historical and cultural orientation of upbringing and education, which involves the organization of the educational process based on the history and culture of the peoples living in the region, the country; integration of educational disciplines (mastery of art in unity with the study of songs, music, traditions, rituals, etc.); identification and self-actualization of the individual, based on the introduction of knowledge about man and society into the content of the development of humanistic worldview education; harmonization of interethnic relations. We note that this direction of education is able not only to take into account the interests of national cultures and regional cultural traditions, but also the needs of the individual in national and cultural self-identification, the development of the worldview positions of the individual. Therefore, at the current stage, we consider the development of a humanistic worldview as a way to return lost spiritual values, moral and aesthetic norms of behavior, interpersonal relations, family and everyday life. In our opinion, it is humanistic, ethno-cultural education that can help students master the culture of their people (the culture of consumption, the culture of communication, the culture of knowledge, the culture of work), develops a worldview, makes it possible to organize artistic and creative activities, focusing on the national uniqueness of the region. In determining the place and role of humanistic worldview education in out-of-school educational institutions, we consider it as a method that strengthens the effectiveness of education through the introduction of the means of national culture, which will help direct the modern educational and educational process to the formation of ethnic self-awareness, the development of understanding of the role of one's people in world culture. Analyzing the means of national culture used in folk pedagogy, we established that the educational potential of national culture was aimed at forming humanistic, worldviews in children. moral qualities of the individual, a sense of national self-awareness, patriotism, development of creative abilities.

CHARACTERISTICS OF MEANS AND PEDAGOGICAL CONDITIONS OF HEALTH CARE EDUCATION OF STUDENTS (ON THE BASIS OF THE WORKS OF UKRAINIAN AND POLISH SCIENTISTS)
Authors: Slyvka Larysa
Published: March 2023

The article states that the definitions of the term «health education» in the Ukrainian scientific pedagogical space are vague and somewhat vague. The functional and structural means and pedagogical conditions of health education are singled out. The content and forms and methods of the specified pedagogical process are considered in the research by means of practical implementation of health education. The pedagogical conditions include a set of measures that are created consciously to ensure the greatest effectiveness of health education, namely: theoretical and methodological training of teachers to implement the appropriate educational impact; interaction and cooperation of different subjects of education. Functional and structural means and pedagogical conditions of health education (HE) are united into four groups: semantic dimension of HE; technological dimension (methods and forms) HE; subject-institutional dimension of HE; professional and competence dimension of HE. Each of the measurements is briefly described. It is determined that the content of education is a set of knowledge, skills and abilities that must be acquired in the process of studying the basics of science. Reflections of educational content are curricula, programs of academic disciplines, educational programs, special educational and methodical materials. The content of health education is quite extensive: it covers all dimensions of health physical, social, mental, spiritual. The technological dimension (forms and methods) of health care is related to the need to form in students the appropriate views and beliefs that can become the core of behavior to maintain health. The determining factor in the effectiveness of health education is the availability of qualified professionals. The most important area for the implementation of health education is the school, but the success of educational effects on health is directly related to the broad involvement in the educational process of various state and public structures.

Keywords: health education, pedagogical conditions, means of education, works of Ukrainian and Polish scientists.

The experience of organizing training shows that participants who are familiar only with the basic use of digital tools, tend to apply them more meaningfully in their teaching practice. The research proves, a competent teacher is able not only to use but also to create innovative developments, taking into account their maximum potential in the educational context.
THE LATE XXth AND EARLY XXIst CENTURY WORLD LITERATURE AS A FACTOR IN SHAPING THE HISTORICAL MEMORY OF FUTURE TEACHERS
Authors: Trukhan Oksana
Published: March 2023

It is noted that fiction for various reasons loses its educational role among future teachers, and a certain educational potential of modern world literature is virtually unfamiliar to students. It has been proved that modern foreign literature, which actualizes Ukrainian issues, can become an effective means of educating spirituality, national-patriotic feelings and historical memory in future teachers. The interest of foreign authors in Ukraine, its historical past, raising of important issues of national identity, historical memory of Ukrainians is a stimulus for students to get acquainted with these literary works and to read them deeply. The object of study may be the novel "Chornobyl Prayer: A Chronicle of the Future" by the Nobel Prize-winning writer Svetlana Alexievich , as well as Taisa Bondar (the novel "In the Name of the Father and the Son"), Ivan Shamyakin (the novel "The Evil Star") , the American writer Irene Zabytko ("The Sky Unwashed"), representing diaspora literature, the novel by the Irish writer Darragh McKeon "All That is Solid Melts into Air", the literary work of the French illustrator Emmanuel Lepage "Springtime in Chernobyl", journalism of the American-English scholar Serhii Plokhy ("Chernobyl: The History of a Nuclear Catastrophe”) and others. These authors are thematically united by the Chernobyl accident, which they portray as a global catastrophe, as a national tragedy of Ukrainians, a huge psychological trauma for people. The writers emphasize that the Chernobyl explosion happened not only due to neglect of safety rules, problems with the construction of the reactor or staff errors, but also largely due to the socio-political system and the authoritarian regime of those times. Today, more than ever, these problems are urgent, especially taking into consideration the events that took place at the Chernobyl nuclear power plant as a result of the invasion of Russian troops. Unfortunately, there is a great threat of a repeat of this catastrophe. Therefore, the artistic and journalistic works of the “Chernobyl discourse” must be read carefully and in a new way, in order to prevent a recurrence of the Chernobyl disaster. The lessons of Chernobyl must not be forgotten and should never be allowed to happen today. Such issues are perhaps the most capable of shaping the national memory of youth, national consciousness and high spiritual values.

Keywords: modern world literature, future teachers, historical memory, education, Chernobyl discourse, writers.
Scaling-up of simultaneous saccharification and fermentation of lactic acid from microwave-alkali-treated empty fruit bunches
Authors: Hassan Nursia , Idris Ani , El-Enshasy Hesham Ali , Malek Roslinda Abd.
Published: March 2023

The goal of this work was to scale up the simultaneous saccharification and fermentation (SSF) of lactic acid using microwave-alkali-pretreated empty fruit bunches (EFB) from a scale of 16 L to a scale of 150 L. To facilitate the scaling-up process of lactic acid production by Rhizopus oryzae NRRL 395, a scaling-up criterion of constant kLa value was applied. Operating conditions, such as aeration rate and superficial velocity, were varied and evaluated on both scales (16-L and 150-L). The highest lactic acid yield of 6.8 g/L was obtained under an operating condition of 1 vvm (0.061 s-1). Parallel aeration rates were determined for the 150-L fermenter system to obtain the same kLa value as the 16-L fermenter. An operational condition of 0.5 vvm dissolved oxygen supply in the 150-L fermenter was optimal to support an identical value of kLa and production rate of lactic acid for both scales.
Improvement of the physical properties of paper sheet-lignophenol composites prepared using a facile impregnation technique
Authors: Zhu Lulu , Liu Hanqing , Qian Shuang , Dai Hongqi , Ren Hao
Published: March 2023

Lignophenol was separated from bamboo (Sinocalamus affinis) using a phase separation system. Different concentrations of a lignophenol-acetone solution were used to impregnate hardwood pulp fiber sheets (80 g/m2). The results showed that the tightness, tensile index, tear index, and burst index properties of sheets impregnated with a lignophenol acetone solution (80 g/L) increased 5.66%, 160.08%, 93.66%, and 140%, respectively, compared with sheets prepared without lignophenol. The lignophenol-hardwood pulp fiber composites were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and total reflectance Fourier transform infrared spectroscopy. The results indicated that lignophenol uniformly adhered to the pulp fibers but no chemical bonding occurred. Additionally, both virgin and recycled softwood pulp fiber sheets (80 g/m2) were tested using the same method. Although the strength of all composites increased after impregnation, the most obvious improvement was observed in the hardwood pulp-based composite. This simple method improved the physical strength and hydrophobicity of the composite sheets.

Published: March 2023

Citric acid has been investigated as a good adhesive for particleboard. This research studied the effect of starch addition on the properties of citric acid-bonded particleboard. Starch provides hydroxyl groups that can react with the carboxyl group in citric acid. Three kinds of starches were used in this research, i.e. corn, ganyong (Canna edulis Ker-Gawl), and garut (Maranta arundinacea L.) starches. Petung (Dendrocalamus sp.) bamboo particles were used as raw material. The mixture ratios of citric acid/starch were set at 100/0, 87.5/12.5, and 75/25 (w/w), while the resin content was set at 30 wt.% based on air-dried particles. The boards were then manufactured under pressing conditions of 180 °C for 10 min. Based on the physical and mechanical properties of the particleboards, it was concluded that the addition of starch tended to enhance the mechanical properties, while decreasing the physical properties of the boards. An addition of 12.5 wt.% starch in citric acid was the optimum resin ratio for manufacturing bamboo particleboard. Maranta and canna starches provided higher mechanical properties compared to corn starch. A FTIR analysis clearly showed that the intensity of carbonyl groups increased with increasing of starch content, which indicated that crosslinking between starch and citric acid occurred.
Method for studying water removal and air penetration during through air drying of tissue in laboratory scale
Authors: Sjöstrand Björn , Danielsson Mikael , Lestelius Magnus
Published: March 2023

Energy use, together with consumption of raw materials, machine clothing, and wet end chemicals, are some of the most critical aspects in successful tissue making today. This work was aimed at developing a laboratory-scale method of estimating dewatering mechanisms, vacuum efficiency, and energy use of Through Air Drying (TAD) of tissue. When compared to pilot data, the results of the new laboratory method for investigating dewatering during TAD were in the same magnitude, around 24 to 26% dryness after vacuum dewatering, and 27 to 29% dryness after TAD molding. Sheet properties, such as caliper and surface profile, were evaluated and compared to commercial tissue sheets. The results indicate that it will be possible to precisely measure accurate dryness development and penetrated air volume for tissue sheet forming and TAD molding at a laboratory scale. This can contribute to the efforts of implementing a circular forest-based bioeconomy by increasing the fundamental understanding of dewatering of tissue paper materials, which is facilitated by improvements in energy use. The new method developed in this work will make it easier to assess ideas that are difficult to bring to pilot scale or full scale before learning more of the dewatering capabilities. The authors are convinced that improved knowledge of tissue dewatering mechanisms, forming, and material transport during and after TAD dewatering can increase the efficiency of the industrial manufacturing processes.

Published: March 2023

Effects of high temperature pretreatment and inoculation of Bacillus coagulans were determined relative to the physicochemical properties and bacterial community of aerobic composting of chicken manure. Chicken manure was pretreated with high temperature for 0 h (CJ), 0.5 h (T-0.5h), 1.0 h (T-1.0h), 1.5 h (T-1.5h), and 2.0 h (T-2.0h) and then inoculated with B. coagulans. Chicken manure without high temperature pretreatment was included as control (CK). The results showed that the temperature of manure in CJ, T-0.5h, T-1.0h, T-1.5h, and T-2.0h groups was 2.2 to 8.4 °C higher than the chicken manure in CK within 1 day. On day 3, the chicken manure temperature reached a peak, which was 1.5 to 7.7 °C higher than that in the CK (56.8 °C). Both inoculation of B. coagulans and high temperature pretreatment increased the abundance and diversity of the bacterial community. The abundance of Firmicutes in T-1.5h was significantly higher than that in CJ. In the temperature decreasing period, the abundance of Bacillus in T-1.5h group was significantly higher than that in the CK and CJ. Overall, it was concluded that high temperature pretreatment and B. coagulans inoculation can accelerate the temperature elevation, increase the temperature of compost, and regulate the structure of bacterial community.
Cherubic hymn by Vincenzo Manfredini
Authors: Antonenko Ekaterina , Lebedeva-Emelina Antonina
Published: March 2023

The paper considers Vincenzo Manfredini's «Cherubic Hymn» discovered by E. Yu. Antonenko in 2018. Until recently, it was only known that Manfredini composed music for the Orthodox Church, but not a single composition was found. Based on analysis of manuscript sources, the work is dated to the period of 1762–1765, which allows us to claim that Manfredini was one of the first authors who composed Orthodox Church music in the new classical style that replaced the older partes style after 1762. "Cherubimskaya" is contained in singing books written in round notation, stored in the fund collection "Cult Music" of the Russian National Museum of Music (Moscow): RNMM. F. 283. N 937, sheet 87 (treble), N 256, sheet 7 (viola), N 878, sheet 30v. (tenor), N 996, sheet 65v. (tenor), N 879, sheet. 19 vol. (bass), N 944, l. 17 (bass). With a high probability, these chanting vowels are of Petersburg origin, and, thus, the indication of Manfredini's authorship is credible. The Italian composer Vincenzo Manfredini visited Russia twice: 1758-1769 and 1798-1799. By order of the St. Petersburg Court, he composed chants for the Orthodox Church
Machine learning models applied to predicate post activity oxygen saturation levels
Authors: Wang Yu
Published: March 2023

Machine learning is a rapidly growing field with widespread application in various industries, including healthcare. In recent years, significant advancements in machine learning have enhanced our understanding of data analytics and prediction models in analyzing physiological data, such as blood oxygen levels, heart rate, and blood pressure. This paper focuses on physical activity in adolescence during the pandemic period. The study showed that going outside for a short walk can increase blood oxygen levels. Furthermore, the consumption of certain foods can also raise oxygen saturation levels. Maintaining a high blood oxygen level during exercise can improve athletic performance and reduce injury risk. However, during exercise, the blood oxygen level tends to decrease as the heart rate increases to supply more oxygen to the body. When the blood oxygen level drops too low during exercise, it can lead to fatigue, shortness of breath, and even fainting. By tracking heartbeats, blood oxygen levels, and other physiological parameters during exercise with the YAMAY Smart Watch wearable device, individuals can gain insights into their body's response to physical activity and adjust their exercise routine accordingly. After collecting data using wearable devices and mobile apps, machine learning algorithms can be trained to predict changes in physiological parameters of post-activity, providing valuable insights into the effectiveness of different exercises and identifying potential health risks. Our study used supervised machine learning classification algorithms to predict the expected data with the target data. We used K-fold cross-validation techniques to split the dataset into training, validation, and test sets for the supervised machine learning classification algorithms. After testing each of the machine learning models (K-Nearest Neighbor (KNN), Naïve Bayes, and Random Forest), it was found that the Random Forest had the best prediction accuracy of 98.75%. On the other hand, KNN had a poor prediction accuracy, lower than 41.1%. Therefore, the Random Forest model can accurately predict the effect of change on the oxygen saturation level during exercise.
Cadenas y especialización funcional latinoamericana. Evidencias sobre integración productiva en el siglo XXI
Authors: Roitbarg Hernán Alejandro
Published: March 2023

Este artículo analiza la inserción latinoamericana en cadenas de producción globales y regionales, según la especialización funcional desempeñada. Para realizar el análisis se ha construido y armonizado una base de datos sobre ingresos por ocupación para siete países de la región. La metodología se basó en un enfoque de Insumo Producto multi-país. Los resultados indican un perfil de especialización manufacturero basado fundamentalmente en tareas de fabricación. Los casos excepcionales se concentran en Brasil y México, países que también participan por medio de las funciones de dirección e investigación y desarrollo. Los hallazgos implican que la inserción general de Latinoamérica por medio de acuerdos comerciales no ha logrado plantear un perfil de especialización diferente, y sí con efectos levemente positivos, limitados y concentrados en las principales economías de la región. Para lograr mejores resultados, se identifica como desafío la coordinación de políticas que promuevan el crecimiento de la demanda intrarregional en conjunto con políticas que guíen las economías de aglomeración, a los fines de un reparto más equitativos de la participación en las etapas productivas y los ingresos derivados.

Sin embargo, esta última parece no haber sido distribuida en todos los segmentos de la población de forma igualitaria. Este artículo presenta una evidencia econométrica de la relación entre el nivel del comercio internacional y la desigualdad de ingresos intra-país para 150 países de los cinco continentes, en el período 2012-2020. Los modelos propuestos son de tipo panel de efectos fijos y aleatorios, controlados por continente. Entre los principales resultados se encuentran que cada una de las regiones evidencian efectos diferentes entre el nivel de comercio internacional y la desigualdad de ingresos intra-país. Para el año 2020, los efectos del Covid-19 sobre la desigualdad no son determinantes, pues aún no existen suficientes datos públicos para medir el efecto de la pandemia cuantitativamente, aun así, se puede colegir, a partir de fuentes secundarias y de estadística descriptiva, que hubo un incremento en la desigualdad de ingresos en los países producto del confinamiento.

El cambio climático, como fenómeno antropogénico y natural, conlleva afectaciones y cambios percibidos en diferentes formas y proporciones por las comunidades, que responden de manera espontánea y adaptan su estilo de vida a estos. La presente investigación se centró en la identificación, comprensión y análisis de las experiencias y prácticas socioculturales ante el cambio climático de la comunidad de pequeños productores campesinos de las veredas Alto Grande y Bravo Páez del municipio de Jesús María (Santander, Colombia). La investigación, de tipo hermenéutico y método interpretativo, tuvo como unidad de trabajo 21 informantes clave, seleccionados bajo criterios de conocimiento de la comunidad y el territorio, jóvenes de la comunidad y personas con reconocimiento y liderazgo; mientras que la recolección de información se realizó mediante entrevistas semiestructuradas. La comunidad percibe el cambio climático como un fenómeno ligado al aumento de la temperatura y de las precipitaciones, y en general al cambio de los patrones climáticos que conocían, cuyas principales consecuencias se relacionan con la pérdida de fuentes hídricas (aljibes), fauna y flora, la erosión del suelo, la aparición de otros fenómenos naturales como vendavales y la disminución en la producción de alimentos. La preocupación por dichas alteraciones los ha llevado a buscar diferentes alternativas para adaptarse y mitigar los efectos del cambio climático, así como para cuidar la naturaleza. Este accionar demanda de manera constante mayor apoyo institucional y gubernamental, de orden local y regional, así como la implementación y participación de la comunidad en programas de educación ambiental.

El estudio de los sellos y reservorios es el objetivo principal de la petrofísica, dentro de la cual, los registros geofísicos de pozo cumplen un papel importante. La mejor opción para caracterizar las formaciones en los pozos es la descripción litológica de los núcleos y las muestras de canal, lo cual se complementa con la información continua que brindan los registros de pozos. Entre las rocas sellantes, se destacan mayormente las que son arcillosas, y se caracterizan por tener valores de resistividad baja, porosidad muy alta, valores elevados de radiactividad natural y presencia de derrumbes en los registros convencionales, mientras que, en los registros de imágenes de pared de pozo, lo típico son los colores más oscuros de la gama. En la práctica, estas características no son tan evidentes en todas las rocas que se definen como sellos arcillosos, ya que su composición y propiedades varían, y constituye un problema, en muchas ocasiones, identificar, a partir de la visualización de los registros, la formación a la que pertenecen esas rocas. La Unidad Tectónica Estratigráfica Placetas, dentro de la Provincia Norte Petrolífera Cubana, está constituida por una serie de formaciones. La Formación Constancia se considera como una transición entre las rocas clásticas sinrift y las rocas carbonatadas propias de las formaciones que constituyen reservorios dentro de la Unidad, mientras que Vega Alta es la cubierta sinorogénica que preserva los hidrocarburos de las formaciones productivas.
Las formaciones Constancia y Vega Alta, suelen confundirse en los pozos, en la geología compleja de mantos y escamas en que aparecen. En este trabajo se integran los elementos geólogo-geofísicos disponibles para estudiar las diferencias y similitudes que presentan las rocas arcillosas en diferentes contextos y se analiza la identificación con las formaciones señaladas. Los gráficos de propiedades cruzadas de registros geofísicos ayudan en la identificación litológica en conjunto con la representación de los registros compuestos. Un rol destacado en la caracterización, lo juega el registro de imágenes, porque permite definir la textura de las rocas. Por último, la variación de los distintos registros geofísicos puede resumirse en los gráficos de estrella como estudio estadístico de cada paquete analizado. Como resultado se caracterizaron cuatro grupos litológicos de rocas arcillosas, a los que se les llamó electrotipos por su relación con los perfiles de pozo, gráficos e imágenes, y su relación las formaciones Vega Alta, Constancia u otra formación arcillosa en otras unidades tectónicas estratigráficas.
Atténuation du ground roll par le filtre surface wave atténuation : application pour le cas des données sismiques

L’étape de l’interprétation sismique reste tributaire de la qualité des enregistrements des données, souvent affectés par des bruits cohérents et incohérents. Le but principal de ce travail consiste à l’utilisation du filtre "Surface Wave Noise Atténuation" basé sur la transformée de Fourier afin d’atténuer le bruit de surface présent sur une section sismique sommée en couverture multiple. Le filtre proposé a été appliqué dans le premier stade de notre test, sur des données sismiques synthétiques sur lesquelles un bruit organisé a été ajouté, tandis qu’en second, le filtre a été appliqué sur des données réelles, pour éliminer dans la mesure du possible le ground roll affectant l’image sismique avant et après sommation.  L’optimisation des paramètres du filtre a permis d’obtenir une qualité sismique acceptable. Le recours à d’autres filtres, le filtre médian et le filtre gaussien en l’occurrence, ont permis d’atténuer le bruit résiduel et les réflecteurs apparaissent d’une façon encore meilleure.
