Published: September 2024

Baubau City has the Buton Kraton Fortress, which is the largest fort in the world and an iconic tourist attraction in the city. Studies regarding tourists' bad experiences related to tourism at the Buton Kraton Fortress have not yet been explored. Bad experiences in cultural tourism activities can give rise to negative sentiments that influence visits to a destination. We used three approaches to explore this negative sentiment, namely interviews with five tourists who had come to enjoy the fort as well as a key person, autoethnography, and netnography. This study aims to explore negative sentiment in the Buton Kraton Fortress. The results show that negative sentiment by tourists, the local community, and online communities most often highlight the problems of waste, spatial and green planning, and city infrastructure. Talking about Buton Kraton Fortress cannot be limited to just the area surrounded by the fort structure but also the surrounding environment. It is very important to note that in planning and managing Buton Kraton Fortress, the approach used must be in line with history and culture itself. The aspects of authenticity, originality, uniqueness, variety, beauty, and integrity are the basis that must always be used because negative sentiment arises when these six aspects are not considered in the planning and management of the Buton Palace Fortress and its surrounding environment.

A lawsuit is inseparably linked to the desired and, in particular, the expected outcome, namely the substantive and authoritative judicial decision. There can be no more fundamental doubt that at least one party to the dispute will not always be satisfied with their statements. If the parties to the dispute have no interest in continuing to litigate, the dispute may also end in an alternative way, other than by a court’s decision on the merits, i.e., by court settlement. But what if the parties to the dispute present the court with a settlement that steals from the creditor? The purpose of this article is to provide an analysis of Slovak and Czech case law on the issue of creditors’ lawsuits against decisions approving a court settlement with reference to lawsuits for the settlement of the community property of spouses.
Die Luxemburger Schwerindustrie unter der deutschen Besatzung 1940 - 1944
Authors: Krier Emile
Published: September 2024

Am 30. Dezember 1918 teilte das Großherzogtum Luxemburg den alliier- ten Regierungen mit: ,,Die Großherzoglich-Luxemburgische Regierung hat die Verträge mit Deutschland über die Zollgemeinschaft und die Eisenbahnen gekündigt. Die Regierung wünscht, mit den Verbandsmächten Verhandlun- gen wegen einer neuen wirtschaftlichen Annäherung anzuknüpfen". Damit wurde ein Wirtschaftsbündnis aufgekündigt, das seit 1842 bestand und, nach anfänglichen Schwierigkeiten, dem Großherzogtum einige substantielle wirt- schaftliche und finanzielle Vorteile brachte. 1919 beginnen auch einige große deutsche Unternehmungen ihre Beteili- gungen an luxemburgischen Betrieben zu veräußern. Als erste verkaufte die Gelsenkirchener Bergwerksvereins AG ihre luxemburgischen Besitzungen an ein belgisch-französisch-luxemburgisches Konsortium; 1920 folgte die Deutsch- -luxemburgische Bergwerks und Hütten AG diesem Beispiel. Auch die Fel- ten+Guillaume Karlswerke aus Köln-Mülheim verkauften 1919 ihren Aktien- besitz an den Hauts Fourneaux et Aciéries de Steinfort an die Société métalur- gique de la Loire. Ebenfalls in der Mittelindustrie veräußerten einige deutsche Unternehmen ihre luxemburgischen Besitzungen und Beteiligungen. Die Ver- käufe hatten zur Konsequenz, daß Deutschland seinen direkten Einfluß auf die luxemburgische Schwerindustrie verlor. Belgische und französische Konzer- ne sollten diese Aufgaben nun übernehmen.

Published: September 2024

The growing scarcity of global resources demands a transition from linear to circular production patterns. This article presents a novel vision for integrating linear and circular production processes within a flexible and autonomous production system to achieve perpetual product use. The approach aims to preserve the added value of products and to integrate the design of product generations and production systems. Within the circular factory, the following core aspects must be examined: predicting functions of products, managing uncertainty in used products and process sequences, learning human action for complex tasks, implementing changeable, autonomous production systems, and enabling knowledge modeling for the circular factory across domains. Aspired results are a design for circular factory, effective strategies for uncertainty management and autonomous systems adaptation as well as the externalization of operational knowledge. This research is part of the Collaborative Research Center (CRC) 1574, which explores these aspects in detail. For an in-depth understanding of specific components, it is referred to other publications by the CRC 1574.
TAK-242 alleviates diabetic cardiomyopathy via inhibiting pyroptosis and TLR4/CaMKII/NLRP3 pathway
Authors: Zhao Xiaolong , Zhang Jing , Xu Feng , Shang Longqi , Liu Qingquan , Shen Chunjian
Published: September 2024

Diabetic cardiomyopathy (DCM) is identified as a progressive disease that may lead to irreparable heart failure. Toll-like receptor (TLR) signaling is believed to be implicated in the pathogenesis of DCM. This study intended to explore the potential impact of Toll-like receptor 4 (TLR4) on DCM in vitro and in vivo. Streptozotocin and HG medium were utilized to induce diabetes in animal and cell models, respectively. Selective TLR4 inhibitor TAK-242 and calcium/calmodulin-dependent protein kinase-II (CaMKII) inhibitor KN-93 were employed to explore the involvement of TLR4/CaMKII in DCM. TLR4 expression was increased in DCM hearts, while inhibition of TLR4 activation by TAK-242 improved cardiac function, attenuated heart hypertrophy, and fibrosis, as well as reduced oxidative stress and proinflammatory cytokine levels in rats, which were confirmed by Doppler echocardiography, hematoxylin and eosin staining, and Masson Trichome staining and specific enzyme-linked immunosorbent assay kits. Besides, the expression of hypertrophy-related molecules and oxidative stress damage were also inhibited by TAK-242. Furthermore, TAK-242 treatment reduced CaMKII phosphorylation accompanied by decreased expression of NOD-like pyrin domain-containing protein 3, gasdermin D (GSDMD), The N-terminal domain of Gasdermin D (GSDMD-N), apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC) and Caspase-1 both in vivo and in vitro. Similar positive impacts on HG-induced pyroptosis were also observed with KN-93 treatment, and this was achieved without affecting TLR4 expression. Collectively, our work suggested that TAK-242 demonstrated substantial benefits against DCM both in vivo and in vitro, potentially attributed to the suppression of the TLR4-mediated CaMKII/NLRP3 pathway activity.
Oral glucose tolerance test curve shape in Mexican children and adolescents with and without obesity

Published: September 2024

Objectives

Mexican children with obesity are at a higher risk of developing type 2 diabetes mellitus (T2DM). The aim of the study was to compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic.

Methods

Cross-sectional study including 143 children. Groups were divided into (a) obese: biphasic (B-Ob) (n=55) and monophasic (M-Ob) (n=50), (b) without obesity: biphasic (B-NonOb) (n=20) and monophasic (M-NonOb) (n=18).

Results

Late glucose peak was more frequent in the M-Ob group (p<0.001). Glucose levels ≥155 mg/dL and MetS were more frequent in the M-Ob group but did not show significance. The groups with obesity (biphasic and monophasic) had higher indices of insulin resistance and insulin secretion compared to the nonobese groups (biphasic and monophasic) (p<0.001). AUC glucose was higher in the M-Ob group (p<0.05), and AUC insulin was higher in the M-NonOb group. oDI (Matsuda) was significantly lower in the M-Ob group compared to the other groups (p<0.001), and oDI-HOMA IR was higher in M-NonOb group (p=0.03).

Conclusions

All OGTT parameters could help to identify Mexican children at increased risk of developing T2DM, not only fasting plasma glucose and 2 h glucose. M-Ob in non-T2DM Mexican children reflects an early defect in glucose metabolism. Higher level of IR indexes in M-NonOb vs. B-NonOb could indicate an increased risk for T2DM of genetic origin.
The southeasternmost area of the long barrow cemeteries of the Funnel Beaker culture in the 4th millennium BC. The case of two newly investigated structures in Pawłosiów forest (Subcarpathian loess region, Poland) in the context of the settlement network

Published: September 2024

The eastern part of the Subcarpathian loess region (the Rzeszów Foothills and the Lower San Valley) may now be referred to as the southeasternmost zone of the occurrence of the long barrow cemeteries of the Funnel Beaker culture. In recent times, new intriguing mounds have been discovered in Pawłosiów forest through the utilisation of LiDAR data sources. In order to investigate whether these structures are long barrows built by “beakers” communities, we have carried out preliminary geophysic research, geological drillings, and lithological analysis. As a result, we confirmed the anthropogenic origin of both structures. The main feature registered during the fieldwork was the lithological and stratigraphical difference between the mounds and their direct geological context. Moreover, a presence of an archaeological feature was identified within the frontal part of one of the mounds. These facts, together with key information regarding the location of both earthen structures in the field and their spatial relationship to the nearby FBC settlement at site 52 in Pawłosiów, suggest that they may be relics of the FBC long barrows. In this study, we also discussed these mounds in the context of their spatial-chronological position in the settlement network(s). It is plausible that the inhabitants of Pawłosiów 52 settlement were responsible for the construction of both long barrows in the period ca. 3650–3400 BC. Additionally, we do not exclude the possible alternative (non-funeral) functions and meanings of the cemetery.
Pflegende Studierende: Soziale Ungleichheiten in und Belastungen durch die (Nicht-)Vereinbarkeit von Pflege und Studium

Care work is mostly done by family members. While the (non-)reconciliation of care and work has already been researched in numerous studies, the state of research on studying and caring for (older) adults, such as one’s own parents or grandparents, has gaps. This paper, thus, asks: How many students engage in caregiving activities? How are caregiving activities socially distributed among the group of students? What burdens result from the (non-)reconciliation of study and care? In order to approach these questions, a university-wide online survey was conducted at the University of Stuttgart in October 2021, in which a total of 1622 students participated. Methods of analysis included logistic and linear regressions in addition to descriptive statistics. On the one hand, the results point out that caregiving is unequally distributed: Female and older students show a higher probability of caring for an older person during their studies. This also applies to students with a migrant background. On the other hand, students who are caregivers more often feel overburdened in various areas of their lives, from their studies, their partnership to their own health. This points to the accumulation of social inequalities – those who are already disadvantaged are more likely to find themselves in a care situation and, thus, experience increased stress. We assume that this could have long-term effects on the entire life course (e. g. on academic success, opportunities on the labour market and health).
Business ethics and corporate governance – Nigeria’s Guaranty Trust Bank, ca. 1990–2004
Authors: Olukoju Ayodeji
Published: September 2024

Guaranty Trust Bank (GTB) PLC, a wholly Nigerian business enterprise, founded in 1990, blazed the trail in the banking sector of Nigeria in many respects. By 1995, it had become the fourth most profitable bank in Nigeria and the first indigenous bank to attain a profit-before-tax of one bn naira, and by 2002 had expanded into several West African countries. The significance of the bank is attested by several scholarly studies of its founding, growth, performance and impact. This paper examines a neglected aspect of the history of the bank: its successes and failure in complying with standards of corporate governance and business ethics in a notoriously opaque industry. Specifically, it focuses on the GTB’s relations with statutory regulatory bodies – the Central Bank of Nigeria (CBN) and the National Deposit Insurance Corporation (NDIC) – as well as its shareholders, who kept the bank on its toes on matters of its business operations. Relying on previously unexploited sources, including minutes of the bank’s board of directors, annual reports and oral evidence provided by members of the board, management and staff, and former top employees of the bank, as well as snippets from the reports of the regulatory bodies (which are not to be cited), this paper highlights issues raised by stakeholders about how the bank managed its affairs, and how it dealt with the queries and questions raised by the external regulators and internal stakeholders in the first 15 years of its existence.
Interpersonal Psychotherapy: A Review of Theory, History, and Evidence of Efficacy
Authors: Stuart Scott , Schultz Jessica , Molina Abigail Palmer , Siber-Sanderowitz Shaina
Published: September 2024

Interpersonal psychotherapy (IPT) is an empirically validated treatment for mood disorders, anxiety disorders, eating disorders, and trauma. IPT is based on the concept of “relational frame”—that an individual's experience of psychological distress impacts those around them, and that their social support network impacts the distressed individual. This concept, along with the specific techniques and tools that flow from it and the theoretical bases of IPT (attachment and interpersonal theory) make IPT unique. In this article we review the theoretical bases of IPT (attachment and communication) and provide a brief history of IPT, as well as the evidence supporting its use for a variety of disorders. We also describe its application to groups, adolescents, and other diverse populations. Future directions for research and treatment development are proposed, particularly research in the area of combining IPT with other psychotherapeutic modalities.

Large-scale genome-wide association studies (GWASs) have associated intronic variants in
PDE4B
, encoding cAMP-specific phosphodiesterase-4B (PDE4B), with increased risk for post-traumatic stress disorder (PTSD), as well as schizophrenia and substance use disorders that are often comorbid with it. However, the pathophysiological mechanisms of genetic risk involving PDE4B are poorly understood. To examine the effects of PDE4B variation on phenotypes with translational relevance to psychiatric disorders, we focused on PDE4B missense variant M220T, which is present in the human genome as rare coding variant rs775201287. When expressed in HEK-293 cells, PDE4B1-M220T exhibited an attenuated response to a forskolin-elicited increase in the intracellular cAMP concentration. In behavioral tests, homozygous
Pde4b
M220T
male mice with a C57BL/6JJcl background exhibited increased reactivity to novel environments, startle hyperreactivity, prepulse inhibition deficits, altered cued fear conditioning, and enhanced spatial memory, accompanied by an increase in cAMP signaling pathway-regulated expression of BDNF in the hippocampus. In response to a traumatic event (10 tone–shock pairings), neuronal activity was decreased in the cortex but enhanced in the amygdala and hippocampus of
Pde4b
M220T
mice. At 24 h post-trauma,
Pde4b
M220T
mice exhibited increased startle hyperreactivity and decreased plasma corticosterone levels, similar to phenotypes exhibited by PTSD patients. Trauma-exposed
Pde4b
M220T
mice also exhibited a slower decay in freezing at 15 and 30 d post-trauma, demonstrating enhanced persistence of traumatic memories, similar to that exhibited by PTSD patients. These findings provide substantive mouse model evidence linking PDE4B variation to PTSD-relevant phenotypes and thus highlight how genetic variation of PDE4B may contribute to PTSD risk.
POPULATION AGEING AND THE CHALLENGES FACED BY OLDER PERSONS IN LESOTHO
Authors: Dhemba Jotham , Makofane Mankwane Daisy Maria , Mabetoa Maria
Published: September 2024

The decline in inter-generational solidarity as a result of socio-structural processes such as modernisation, globalisation and migration have made older persons in many African countries increasingly vulnerable. The aim of this study was to gain an in-depth understanding of the challenges faced by older persons in Lesotho and how to address them. The study adopted a qualitative approach, while snowball and purposive sampling were employed to recruit older persons and social workers, respectively, for the study. Data were collected by means of semi-structured interviews. Poverty, food insecurity and ageism were found to be the major challenges faced by the older persons. Although eligible older persons receive old age pensions or public assistance, these are not effective in addressing poverty. Social workers should embrace the developmental approach, which involves advocacy, the implementation of income-generating projects, building assets for the poor, and productive employment to create opportunities for the long-term social security for older persons.

Giant bells in Siberia in the 17th — 20th centuries: monuments of casting and the cultural significance
Authors: Talashkin Alexey
Published: September 2024

There is fragmentary information about giant bells in Siberia; the topic of studying this phenomenon has not been raised before. The article gives and justifies the definition of a giant bell. Bells weighing 500 pounds or more were found in most large provincial Siberian cities; in some cases (Tobolsk, Kungur, Pyskor, Nizhny Tagil, Irkutsk) there were several such bells. It is noted that in Siberia, which has experienced a shortage of bells throughout the entire Orthodox period of existence, bells of smaller weight can also be considered giants. Giant bells were the subject of special concern of kings and bishops and had great cultural significance in the life of Siberians. Notifying local residents about the most important events not only in the church and state life of the country, the ringing of such bells was a kind of mass media for the population. In the conditions of low-rise buildings in Siberian settlements, this ringing covered not only the entire territory of the city, but was often heard in neighboring settlements. During the research, the problem of attribution of bells in terms of their weight arose. It turned out that in various pre-revolutionary sources the same bell can have different data; often the weight was rounded to some more convenient values, both up and down. Of the 22 bells described in the article, not a single giant survived after the anti-bell campaign of the 20th century; all of them were destroyed. The article raises the issue of restoring the lost bell heritage and provides data on the existing giant bells cast at the beginning of the 21st century.

The paper is devoted to the study of the characteristics and operating modes of a brushless magneto-electric tachogenerator, which is implemented on the basis of a traditional radial electric machine with a slotless stator and permanent magnets on the rotor. Options for generating an DC output signal using diode and transistor rectifiers have been studied. The dependences of the average value of the output signal, the slope of the output signal, the coefficient of deviation of the characteristic from the specified value and the pulsation coefficient were obtained depending on the rotation speed of the rotor shaft. The influence of the capacitance of the filter capacitor on the magnitude of the output signal ripple amplitude has been studied. Ref. 13, fig. 9, table.

BACKGROUND

Rotavirus was the leading cause of acute gastroenteritis among US children until vaccine introduction in 2006, after which, substantial declines in severe rotavirus disease occurred. We evaluated rotavirus vaccine effectiveness (VE) over 13 years (2009–2022).

METHODS

We analyzed data from the New Vaccine Surveillance Network using a test-negative case-control design to estimate rotavirus VE against laboratory-confirmed rotavirus infections among children seeking care for acute gastroenteritis (≥3 diarrhea or ≥1 vomiting episodes within 24 hours) in the emergency department (ED) or hospital. Case-patients and control-patients were children whose stool specimens tested rotavirus positive or negative, respectively, by enzyme immunoassay or polymerase chain reaction assays. VE was calculated as (1–adjusted odds ratio)×100%. Adjusted odds ratios were calculated by multivariable unconditional logistic regression.

RESULTS

Among 16 188 enrolled children age 8 to 59 months, 1720 (11%) tested positive for rotavirus. Case-patients were less often vaccinated against rotavirus than control-patients (62% versus 88%). VE for receiving ≥1 dose against rotavirus-associated ED visits or hospitalization was 78% (95% confidence interval [CI] 75%–80%). Stratifying by a modified Vesikari Severity Score, VE was 59% (95% CI 49%–67%), 80% (95% CI 77%–83%), and 94% (95% CI 90%–97%) against mild, moderately severe, and very severe disease, respectively. Rotavirus vaccines conferred protection against common circulating genotypes (G1P[8], G2P[4], G3P[8], G9P[8], and G12[P8]). VE was higher in children <3 years (73% to 88%); protection decreased as age increased.

CONCLUSIONS

Rotavirus vaccines remain highly effective in preventing ED visits and hospitalizations in US children.

Published: September 2024

Shrimp is an Indonesian’s export commodity with high economic value increasing every year. Usually, shrimps are exported in the form of frozen shrimp without shells, heads, tails, and entrails. It resulted in the accumulation of shrimp waste leading to the increasing environmental pollution. Shrimp waste contains high contents of chitin which can be processed to a chitosan owing several benefits. The purpose of this study is to determine the optimum condition of the synthesis of chitosan from chitin isolated by the autolysis method. The deproteination was carried out by soaking the shrimp waste in an acidic solution (pH 2 – 3) for 10 d. The demineralization process was done by reacting the deproteinated solids in a hydrochloric acid solution at pH 0 – 1 for 24 h. Parameters varied in this study time (1 – 3 h), chitin to NaOH ratio (1:10 – 1:30 (w/v)), and temperature (60 – 120℃). The higher all parameters used, the higher the obtained degree of deacetylation (DD) which is in the range of 18.35±1.13 to 48.6±0.51%. On the other hand, the obtained yield decreased from 50.66±1.98% to 47.78±0.81%. The optimum condition was obtained at a synthesis temperature of 120℃, chitin to NaOH ratio of 1:20 g/mL, and time of 3 h producing chitosan with DD of 54.25 ± 2.27%, and yield of 47.7 ± 0.65%. Chitosan synthesized using optimum conditions produced a relatively homogeneous thin film. Polyaniline was then introduced to the film to obtain a smart film prototype. This smart film was able to detect the pH changes proven by the change in its color. The smart film also could be potentially used as a “smart pack” for detecting product decay which releases ammonia gas.

In this study, nitrocellulose - polymethyl methacrylate (NC/PMMA) blend film as a positive triboelectric material for triboelectric nanogenerator (TENG) with controlled flexibility was successfully synthesized by varying the PMMA content in the polymer blend. The combination of NC and PMMA reduced the limitations of the individual component materials with improved mechanical properties such as tensile strength, elastic modulus and elongation at breaking point. The TENG fabricated from NC/PMMA as a positive friction layer paired with fluorinated ethylene propylene (FEP) or polytetrafluoroethylene (PTFE) as a negative friction layer demonstrates a high peak to peak voltage output of 234 V at low frequency and with an actuation force of 10~N. The open circuit triboelectric voltage value maintains 91% durability after 26200 click-release cycles. This work provides a potential approach to simultaneously improve the electrical and mechanical properties of triboelectric materials, promoting the possibility of practical applications of TENG.
„W tej sytuacji sprawę znów odłożono”. Kwestia prawosławia w województwie krakowskim na marginesie sprawozdania Wydziału do spraw Wyznań z 1969 r.
Authors: Bobryk Witold
Published: September 2024

After World War II, the displacement of the population irreversibly changed the ethnic and religious structure of south-eastern Poland. The Lemko people who lived in the districts of Nowy Sącz and Nowy Targ were displaced from the area of the Kraków voivodeship. Most of the people belonging to this ethnic group were of the Greek Catholic faith. In the interwar period, however, some of them converted to Orthodoxy. There were nine churches of this religion in the Nowy Sącz district. All of them were closed due to the displacement of the faithful. The liberalization of the system allowed expatriates to return. For many reasons only few of them returned. None of the Orthodox parishes in the Krakow Province resumed their activities. However, efforts were made to set up pastoral centers. This was met with the reluctance of the local authorities. In 1969, the national religious administration conducted a survey on the functioning of the Orthodox Church in the country. In response, a report was prepared on the situation of this religion in the Krakow Province.

Published: September 2024

Many researchers seek to identify the most common factors that may increase the risk of wars, including civil wars. However, analysing the causes and economic drivers of conflict is receiving increasing attention, especially concerning civil wars in the poorest regions. The main purpose of this article is to present the process of creating armed groups in Darfur, as well as their ideology, internal divisions, stages of conflict and the emergence of these groups. This study attempted to analyse the motives and objectives of Darfuri rebel groups. Using a model created by Spittaels and Hilgert, we explain the relations between events on the ground and the motives and objectives behind the waging of a war, which in future could make it easier to outline the essence of the conflict.

Published: September 2024

The article presents the results of a study of various low-carbon energy sources based on a multi-criteria analysis for the purpose of a comprehensive environmental and economic assessment of the effectiveness of their use. The peculiarity of the study is that it analyzed both renewable energy sources and traditional fossil fuel based ones using innovative technologies for carbon dioxide capture and storage, as well as nuclear energy. The purpose of this work is to conduct a comprehensive assessment based on three criteria: normalized cost of electricity LCOE (Levelized Cost of Energy)/LEC (Levelized Energy Cost), specific value of carbon dioxide emissions and material intensity expressed in total MI (Material Input) numbers. The hypothesis of the study is as follows: the introduction of the criterion of material intensity in MI numbers into a comprehensive assessment will allow one to identify low-carbon energy sources with the greatest ecological and economic effect. As a result, it was found that in 2023, the global energy capacity of low-carbon energy sources reached 51.8%, but the share of energy produced by them is significantly lower, amounting to only 39.4%. The multi-criteria analysis made it possible to identify low-carbon energy sources that, at the lowest cost, provide the greatest reduction in carbon dioxide emissions, and at the same time reduce the overall environmental impact by reducing the disturbance of biospheric material flows. Wind farms have high ecological and economic efficiency, while solar energy sources and bioelectric power plants – slightly less so. Geothermal and hydroelectric power plants have a low normalized cost of electricity, but they have relatively high values of material intensity. The environmental and economic efficiency of nuclear power is higher than that of gas and coal-fired power plants using carbon dioxide capture technologies; it occupies an intermediate position between renewable and traditional energy sources. An unexpected established fact is that gas and coal-fired power plants with carbon dioxide capture technologies have the same environmental and economic efficiency. The results obtained can be useful in making decisions about the possibility of prioritizing the development of individual low-carbon energy sources.

Regional economies, which are economic subsystems of a socio-ecological-economic system, are characterized by rapidly changing conditions affecting their functioning. Therefore, traditional approaches based on long-term trends and the construction of appropriate models are not enough for modeling and need to be over updated, including through combination with other approaches that take into account the volatility of conditions. Open sources datasets are fraught with uncertainty (different sources may have different values for the same indicator). So, some indicators are being constantly adjusted: changes are introduced into datasets from the previous periods; evaluation periods are not sufficient for model construction that would be methodologically valid from the point of view of mathematical statistics, Additionally, the results of functioning depend on influencing factors as well as measurement results. These problems lead to the need to resort to probabilistic estimates and the incompleteness and fuzziness dataset, as well as to obtain samples of sufficient volume from low-power data. The purpose of the study is to model the relationship between the volume of gross domestic product and the factors characterizing the functioning of the economic subsystem of the regions, under the conditions of uncertainty and limited data in a given period of time. The case study is constructed on The Tula region dataset. The working hypothesis is that it is possible to construct a methodologically correct econometric models using the dataset of a specific region of the Russian Federation over a certain period of time. We applied the methods of econometric modeling and the methodology of Bayesian intelligent measurements, as well as the methodology for generating a sufficient amount of data on small samples. For the Tula region and dataset for 2022, nonlinear models for the GDP by region volumes (14 sections of the NACE) were built. This made it possible to test the presented methodology based on a combination of econometric and Bayesian approaches to modeling the complex systems functioning, with conclusions having both theoretical and practical value for the region's sustainable development.

Expanding horizons in burn care: a new paradigm for General Surgeons in Brazil
Authors: ARAÚJO KELLY DANIELLE DE , FERREIRA ROBERTO MENDES
Published: September 2024

ABSTRACT The role of the burn surgeon in Burn Treatment Centers (BTCs) is crucial for complementing the multidisciplinary approach in the treatment of burn patients. Globally, the areas of General Surgery and Plastic Surgery are the primary surgical specialties dedicated to this function. The structuring of the Burn Patient Care Line in Minas Gerais highlighted the need to expand the “Burn Care” Field of Expertise, extending it to General Surgery. With the inevitable expansion of the Care Line, pioneered by the state of Minas Gerais, to the federal level, the need for specialized surgical training encompasses both the state context and anticipates the national scenario in the short term. Therefore, the expansion of the “Burn Care” Field of Expertise is fundamental to meeting specific demands and improving the quality of care offered to burn patients, in accordance with international standarts.

Published: September 2024

RESUMO: O contexto pandêmico, transformou a realidade social e as relações interpessoais, principalmente por meio das medidas de isolamento e distanciamento social, necessárias para a contenção do vírus. Com o trabalho remoto e a intensificação do convívio familiar, acentuaram-se as desigualdades de gênero relacionadas à divisão sexual do trabalho, que sobrecarrega as mulheres diante da desigual responsabilização pelos cuidados com a vida privada. O presente artigo, de natureza qualitativa exploratória, objetiva, a partir do uso de questionários, investigar de que forma a pandemia impactou a carreira das cientistas mães docentes da Universidade Federal do Pampa, analisando como essas pesquisadoras conciliam o ensino remoto e as demais demandas da carreira científica com a maternidade. Percebemos, por meio da pesquisa, que a pandemia impactou não somente a carreira, mas também a saúde mental e física das participantes, na medida que as sobrecarregou para além das demandas profissionais, como também com as demandas do âmbito privado, como o cuidado doméstico e das(os) filhas(os), assumidas majoritariamente por elas.

RESUMO: Nas últimas décadas houve uma expansão do acesso ao ensino superior no Brasil. A grande procura por cursos de graduação a distância destaca novas formas de acesso ao ensino superior e novos arranjos institucionais dos processos de ensino e aprendizagem. No contexto da educação a distância, o trabalho pedagógico exercido por facilitadores passa a ser importante no processo de aprendizagem dos estudantes. O estudo tem como objetivo analisar as percepções dos facilitadores acerca das experiências pedagógicas vivenciadas na formação continuada de professores do ensino superior da Universidade Virtual do Estado de São Paulo (UNIVESP). A pesquisa é qualitativa e empregou questionário virtual para a coleta de dados durante o primeiro semestre de 2023. Os participantes da pesquisa reconhecem a experiência de ser facilitador como algo importante na sua formação profissional, mas percebem a prática como uma tarefa ambígua devido à combinação de funções docentes e não docentes. Em relação ao curso de formação realizado pelos facilitadores, alguns entendem como uma aproximação inicial com o trabalho pedagógico. Para outros, a formação configura-se apenas como uma renda. Já, outros facilitadores concebem a formação como uma experiência pedagógica importante na carreira, mas apontam limitações. Assim, há uma complexidade da função de facilitador, e as dificuldades existentes na prática pedagógica exigem maior reconhecimento do trabalho pedagógico desses facilitadores.
PEDAGOGIA DECOLONIAL EM INTERFACE COM OS ESTUDOS DO LETRAMENTO: DECOLONIZANDO MONUMENTOS HISTÓRICOS

Published: September 2024

RESUMO Nossa intenção neste artigo é pensar uma proposta didática que entrelace teorias como decolonidade (Mignolo, 2003, 2007; Quijano, 2005; Walsh, 2009, 2013, 2020), estudos do letramento (Street, 2003, 2014; Kleiman, 1995, 2006; Soares, 2003; Rojo, 2009), criticidade (Aguiar, 2022; Freire, 1997, 2006; Carbonieri, 2016) e interculturalidade crítica (Walsh, 2007, 2009, 2010), chegando à constituição do conceito de Letramento Cartográfico Digital Crítico. A ideia é que, por meio de uma pedagogia decolonial, esses conceitos entrem em convergência e, de forma orgânica, a síntese construída a partir do diálogo dessas teorias possa oportunizar outras possibilidades de estar, ser, sentir, existir, fazer, pensar, olhar, escutar e saber (Walsh, 2013) na escola através da produção de mapas virtuais, interativos e decoloniais.
Estudo da corrosão do aço carbono em H2SO4: efeito da adição de íons sulfato

Published: September 2024

RESUMO A compreensão dos fenômenos envolvidos na corrosão do aço carbono em meio H2SO4 é de fundamental importância, visto que este é o principal produto da indústria química. Contudo, poucos trabalhos recentes relacionados a corrosão do aço carbono em H2SO4 em diferentes concentrações de sulfato são reportados. O presente trabalho objetivou estudar a corrosão do aço carbono em H2SO4 1 mol L–1 sob incremento de íons SO42– de origem salina. Medidas de potencial a circuito aberto, ensaios de imersão com perda de massa, quantificação do teor de íons ferro total em solução e curvas de polarização potenciodinâmica foram realizadas e sugerem que a corrosão do aço carbono em H2SO4 com adição de sulfato ocorre por mecanismo de dissolução-passivação, sendo influenciada pela concentração de sulfato adicionado. Micrografias da superfície do aço carbono denotam que a corrosão ocorre de maneira uniforme e com a formação de produtos de corrosão insolúveis distribuídos não homogeneamente na superfície metálica. Tais produtos estão provavelmente associados à precipitação de FeSO4 e/ou Fe(OH)3 na superfície.

Resumo Objetivos: verificar fatores associados ao estresse parental em Unidade de Terapia Intensiva Neonatal (UTI Neonatal) de pequenos municípios. Métodos: estudo quantitativo transversal, com pais de recém-nascidos internados em UTI Neonatal de dois hospitais filantrópicos. Os instrumentos utilizados foram Parental Stress Scale: Neonatal ICU e Percepção do Cuidado Centrado na Família - Pais. A análise foi realizada de acordo com a natureza de distribuição das variáveis. Resultados: de 129 voluntários, 79,8% apresentaram estresse parental. As médias de estresse nos domínios “sons e imagens”, “aparência e comportamento do bebê” e “alteração no papel da mãe/pai” observadas foram, respectivamente, 1,9, 2,9 e 3,7 na Parental Stress Scale: Neonatal ICU. Houve associação significativa entre gênero dos participantes (p=0,018) e intercorrências clínicas durante a hospitalização (p=0,044) com estresse parental. Observou-se diferença nos grupos na variável “tempo de internação até o momento da coleta de dados” (p=0,011), nos domínios “respeito” (p=0,026), “colaboração” (p=0,006) e na soma total (p= 0,011) da escala Percepção do Cuidado Centrado na Família - Pais. Conclusão: estresse parental esteve associado à alteração no papel de mãe/pai; às mães e à ocorrência de intercorrências clínicas com o bebê durante sua hospitalização.

Abstract Objectives: verify the factors associated with parental stress in Neonatal Intensive Care Unit (Neonatal ICU) of small municipalities. Methods: cross-sectional quantitative study, with parents of newborns admitted in the neonatal ICU in two philanthropic hospitals. The instruments used were the Parental Stress Scale: Neonatal ICU and Perceptions of Family-Centered Care - Parents. The analysis was performed according to the nature of the distribution of the variables. Results: of the 129 volunteers, 79.8% showed parental stress. The averages of stress in the domains “sights and sounds”, “baby looks and behaviors” and “alteration in the mother/father role” was observed, respectively, 1.9, 2.9 and 3.7 in Parental Stress Scale: Neonatal ICU. There was a significant association between the gender of the participants (p=0.0182) and clinical complications during the period of hospitalization (p= 0.0443) with parental stress. A difference was observed in the groups of the variable “hospitalization time to the moment of the data collection” (p= 0.0112), in the domains “respect” (p=0.0266), “collaboration” (p=0.0060) and in the total sum (p= 0.0112) of the Perceptions of Family-Centered Care - Parents scale. Conclusion: parental stress was associated with changes in the role of the mother/father; with the mothers and the occurrence of clinical complications with the baby during its hospitalization.
