Authors: Bao Ping , Zhou Yipeng , Wang Xiaowei , Men Jinfeng , Liang Chengqiang , Ding Hao
Published: July 2024

The radionuclides 60Co and 54Mn are the main activation products produced in the operation of nuclear power facilities. Wastewater with these radionuclides must be treated to meet standards before being discharged. A variety of zeolite imidazole frameworks (ZIFs) materials were synthesized at room temperature, and the adsorption effect of ZIF-67 was found to be the best through adsorption experiments on Co(II) and Mn(II). The thermal stability test and structural characterization of ZIF-67 were carried out. At the same time, the influence of the initial pH value, adsorption time, and initial concentration of the solution on the adsorption of Co(II) and Mn(II) by ZIF-67 was investigated. The results show that: ZIF-67 has a microporous structure with a BET surface area of 1,035.72 m2/g. In addition, ZIF-67 has good thermal stability, under the condition of pH = 6, a temperature of 303 K and the initial concentration of 500 mg/L. The saturated adsorption capacity for Co(II) and Mn(II) reached 230.25 mg/g and 338.75 mg/g, respectively. ZIF-67 exhibits good selective adsorption performance for Co(II) and Mn (II) in high concentration interfering ion solutions and multi-ion solutions. The adsorption process of ZIF-67 was analyzed by kinetics, thermodynamics, isotherms, and adsorption diffusion models. The analysis of thermodynamic parameters shows that the adsorption process of ZIF-67 to Co(II) and Mn(II) is spontaneous and endothermic. The pseudo-second-order kinetic model, Langmuir isotherm model, and Boyd model are more in line with the adsorption process of Co(II) and Mn(II) by ZIF-67. It shows that the active sites on the surface of ZIF-67 are evenly distributed, and the adsorption process is single-molecule chemical layer adsorption. In addition, the liquid film diffusion dominates the adsorption rate during the adsorption process of Co(II) and Mn(II) by ZIF-67.
Are calves trainable? Low-intensity calf muscle training with or without blood flow restriction: a randomized controlled trial
Authors: Gavanda Simon , Eisenkolb Matthias , Held Steffen , Geisler Stephan , Gehlert Sebastian
Published: July 2024

Objectives

Whether low-load resistance training (RT) without muscle failure, with or without blood flow restriction (BFR), is sufficient to increase strength and muscle growth of calf muscles in trained individuals is still unclear. This study aimed to compare the effects of low-intensity BFR RT vs. traditional low-intensity RT (noBFR) with moderate training volume on strength and circumference.

Methods

We designed a parallel, randomized controlled trial including 36 RT-trained participants (BFR: 7 females, 32.9 ± 8.8 years, 11 males, 28.4 ± 3.6 years; noBFR; 8 females, 29.6 ± 3.4 years; 10 males, 28.6 ± 4.9 years) who underwent eight weeks of twice-weekly low-load RT with a total of 16 RT sets (30 % of one-repetition maximum [1RM]). RT consisted of bilateral calf raises and seated unilateral calf raises, each conducted with 4 sets (30, 15, 15, 15 repetitions not to failure) of either BFR or noBFR. Outcome measures included calf circumference (CC), leg stiffness (LS), and various strength tests (seated and standing calf raise 1RM, isokinetic strength of plantar- and dorsiflexion).

Results

There were no significant interactions or group effects for most measures. Both groups showed significant improvements in seated calf raise strength (p=0.046, η
2
p=0.17). Pairwise comparisons indicated moderate to large effect sizes for strength improvements (standardized mean differences: 0.35–1.11), but no changes in calf circumference were observed in either group.

Conclusions

Low-load RT with and without BFR are useful to increase strength without necessarily affecting hypertrophy. Low-intensity BFR training did not confer additional benefits over traditional low-intensity RT for calf muscle strength or circumference, questioning its general advantage under such conditions.

Las pruebas estandarizadas se han configurado para evaluar la calidad educativa en países, generar políticas públicas estatales y presentar estrategias de mejora institucional. Las pruebas en razonamiento cuantitativo son motivo de preocupación en Colombia por el bajo desempeño de estudiantes comparado con referentes internacionales. Así,el objetivo de este artículo es analizar factores que afectan los resultados de la competencia Razonamiento Cuantitativo en las pruebas Estatales para la educación superior en Colombia (SaberPro) en estudiantes de administración y afines. La investigación tiene un diseño cuantitativo con métodos que usan variables independientes para determinar impacto en la competencia tanto en importancia (ANOVA) como en probabilidad de ocurrencia (regresión logística). La mayor probabilidad para obtener mejores resultados se puede dar cuando el estudiante es hombre; con título de bachiller normalista; con beca/subsidio, pagó 7 millones COP o más en matrícula; de institución oficial-municipal; universitaria-presencial; de la región andina; con madre con postgrado; con acceso a internet y computador. En conclusión, las políticas públicas deben jugar un papel importante tanto en aspectos meramente curriculares, como en el impacto al contexto socioeconómico de los estudiantes. Para las instituciones corresponde revisar la forma de impartir conocimientos y que sus estrategias correspondan al entorno de los estudiantes.

Authors: Velásquez Ana María , Castellanos Melisa
Published: July 2024

Desarrollar habilidades socioemocionales es una prioridad educativa a nivel mundial. Entre ellas se encuentran las autocreencias, que equipan a los estudiantes con disposiciones motivacionales para alcanzar sus metas académicas. En este estudio se exploró de qué manera el contexto escolar y familiar interactúan para desarrollar autocreencias académicas en una muestra representativa de 2.352 estudiantes colombianos (70,7 % de grado quinto, y 29,3 % de grado noveno). En particular, se analizó la relación entre clima escolar (p. ej., percepción positiva sobre el colegio, relación estudiantes-profesores, organización del aula, estilos docentes), riesgo familiar (p. ej., bajo nivel socioeconómico; baja supervisión, apoyo, afecto y comunicación; maltrato) y autocreencias académicas (i.e., autoconcepto, autoeficacia). Análisis de clases latentes, análisis multinivel de ecuaciones estructurales y comparaciones multigrupo revelaron que: a) el contexto familiar de riesgo se relaciona negativamente con las autocreencias académicas; b) el clima escolar tiene un efecto positivo en las autocreencias académicas; y c) la relación negativa entre el maltrato en el contexto familiar y las autocreencias de los estudiantes de grado noveno desaparece en climas escolares positivos. Estos resultados son discutidos a la luz del rol del clima escolar, tanto directo como indirecto, para favorecer habilidades socioemocionales intrapersonales relevantes para promover el desempeño académico de los estudiantes.
Effects of rice husk biochar attachment biofilm with microorganisms on nitrogen removal of digested swine wastewater
Authors: Pan Fanghui , Huang Fei , Wang Youbao , Zhu Hongguang
Published: July 2024

Nitrogen in digested swine wastewater is currently difficult to directly degrade by an activated sludge process in a sequencing batch reactor (SBR), with resulting failure of the effluent to meet emission standards. In this study, rice husk biochar was optionally added into SBR to enhance biochemical properties for digested swine wastewater, especially for nitrogen degradation. The relative nitrogen removal mechanism for microbial community was probed by means of high-throughput sequencing. The results indicated that chemical oxygen demand (COD), ammonia (NH4+-N), and total nitrogen (TN) removal efficiency of digested swine wastewater was separately at 85.3%, 81.3%, and 65.2% using rice husk biochar with biofilm, which was 3.5%, 24.4%, and 14.7% higher than that of activated sludge, under influent of 2609 mg·L-1 COD, 337.0 mg·L-1 NH4+-N, 344 mg/L TN, and 7.77 C/N. High-throughput sequencing revealed that rice husk biochar with biofilm contained Proteobacteria, Thauera, Comamonas, Acinetobacter, Pseudomonas, Flavobacterium, and Corynebacterium to enhance nitrogen removal of digested swine wastewater. The results not only provide theoretical support for biochar with biofilm to improve digested piggery wastewater treatment, but also have great significance in resource utilization of agricultural waste and eco-environmental protection.

Authors: Lee Hyeonggyu , Lee Yong Ju , Kim Hyoung Jin
Published: July 2024

The mineralization of inorganic components in paper sludge offers potential for their re-use in various fields. This study synthesized carbonates based on the minerals present in paper sludge and aimed to investigate the control of particle size distribution and particle shape of the synthesized carbonates. First, the physicochemical and thermal properties of paper mill sludge and ash were evaluated using a spectrophotometer, XRF, and TGA. Paper sludge ash was obtained by incinerating the paper sludge, followed by a carbonation reaction using CO2 gas injection and pH neutralization to produce recycled fillers. The average particle size, crystal lattice structure, and morphology of the recycled fillers were analyzed using a particle size analyzer, XRD, and FE-SEM. The results indicate that the recycled filler produced from coating paper sludge exhibited similar brightness and morphology to conventional paper-based fillers, suggesting its potential to replace commercial PCC (Precipitated Calcium Carbonate). In contrast, the recycled filler manufactured using old corrugated container mill sludge was deemed unsuitable due to its low hydration activity.

Published: July 2024

Frequent gradual pattern extraction is an important problem in computer science widely studied by the data mining community. Such a pattern reflects a co-variation between attributes of a database. The applications of the extraction of the gradual patterns concern several fields, in particular, biology, finances, health and metrology. The algorithms for extracting these patterns are greedy in terms of memory and computational resources. This clearly poses the problem of improving their performance. This paper proposes a new approach for the extraction of gradual and frequent patterns based on the reduction of candidate generation and processing costs by exploiting frequent itemsets whose size is a power of two to generate all candidates. The analysis of the complexity, in terms of CPU time and memory usage, and the experiments show that the obtained algorithm outperforms the previous ones and confirms the interest of the proposed approach. It is sometimes at least 5 times faster than previous algorithms and requires at most half the memory.

Published: July 2024

Issues related to age are often overlooked when researchers conduct studies of demographic groups in the U.S. workforce. This results in limited understanding of the work experiences of older workers – especially women. In the few studies that have focused on older women, the women who were interviewed disclosed consistent pressure to look young as well as feeling overlooked at work resulting in perceptions of diminished opportunities. This article concludes with recommendations for practice.

The current stage of space exploration is characterized by an increased interest in the development, deployment, and operation of low-orbit satellite constellations (LOSC) for Earth and near-Earth space remote sensing for military and civilian purposes and for global and regional satellite communications. Reusable space launch vehicles have significantly reduced the orbital injection cost. As a result, satellite operators are developing and deploying large-scale LOSCs of various orbital structures with a large number of spacecraft. According to current estimates, more than 70% of all the operating satellites operate in low-Earth orbits (LEOs) at altitudes between 160 km and 2,000 km. Since LEO satellites are generally much cheaper than satellites in geostationary orbits, the possibility of their on-orbit servicing (OOS) has not been the focus of research. However, the use of LEO OOS has prospects for growth. Techniques for ballistic planning of LEO OOS missions have been and are being developed. The disadvantages of approximate techniques include the use of simplified flight dynamics models. Most of the existing exact techniques are based on the use of full mathematical models of flight dynamics and the shooting method to solve the boundary value problem of an orbit transfer. Using the shooting method requires a sufficiently accurate initial guess, which is difficult to determine. To obtain a second approximation, use is mainly made of optimization methods, which do not always find a global minimum. In this regard, there is a need to develop new techniques that would be free from the above disadvantages. The goal of the article is to develop a ballistic planning technique for low-orbit servicing missions with low constant thrust propulsion systems. The technique includes the identification of LEO areas promising for OOS, a mathematical model of the dynamics of perturbed OOS orbit transfers in modified equinoctial orbital elements, and a solution algorithm for the boundary value problem of determining the control parameters of perturbed OOS low-orbit transfers. The problem is solved using methods of statistical analysis, flight dynamics, shooting, genetic optimization, and mathematical simulation. The novelty lies in the identification of LEO areas promising for OOS and the development of a mathematical model of orbit transfer dynamics in modified equinoctial orbital elements and a solution algorithm for determining the control parameters of perturbed OOS low-orbit transfers. The results of the work may be used in the justification and planning of LEO OOS missions and the formulation of requirements for LEO OSS mission propulsion systems.

Solid-propellant rocket engines are simple in design, highly reliable, and able to store the propellant for a long time without its degradation. Their main feature is that the propellant is a mixture of a solid fuel and a solid oxidizer, thus ensuring a uniform combustion and a stable discharge of the combustion products. However, the combustion rate cannot be controlled, and the combustion cannot be stopped or restarted. This calls for efficient methods of thrust vector control. Gas-dynamic methods, such as a gas injection into the supersonic nozzle area, offer a required flight path control without complex high-power mechanical systems. The importance of this study lies in improving the accuracy and efficiency of rocket flight control, which is critical for today’s space and defense tasks. The numerical simulation of gas-dynamic control systems, in particular by an asymmetric gas injection, allows one to obtain detailed data on the flow behavior and optimize the design and operating conditions of the system. This study is concerned with a full-scale solid-propellant rocket engine with a gas-dynamic thrust vector control system based on the use of asymmetric forces that occur on the nozzle wall when the supersonic flow interacts with the injected transverse jets. To simulate the process in the Ansys Fluent software package, a geometric model of a nozzle with an asymmetric injection of the chamber gas into the supersonic area was developed. The injection flow rate was controlled by moving the valve flap. The simulation was carried out taking into account the temperature dependence of the main thermophysical gas parameters with consideration for dissociation processes by way of data approximation. The approximation was performed using piecewise polynomial functions. Nozzle flow patterns were obtained. The calculated results were compared with experimental test data and shown to be in satisfactory agreement with the lateral force measured during the fire bench tests of the prototype. From a practical point of view, the results obtained may be directly used to improve existing thrust vector control systems and develop new ones. This will improve rocket navigation accuracy, flight stability, and maneuverability, which is critical for complex space and defense tasks.
Determination of optimal spacecraft reliability norms with account for economic indexes
Authors: Savonik O.M. ,   Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine
Published: July 2024

The goal of this paper is to develop a method for determining the values of system failure rates optimal in terms of net profit maximization with account for spacecraft mass limitations. It is adopted that the spacecraft systems are independent in terms of reliability, each of them can be only in two states (a functioning state or a failure state), and each equipment type of the special complex makes an independent contribution to the overall effect. The paper considers the case where the spacecraft system failure time obeys the exponential law. Use is made of the Lagrange multiplier method and numerical optimization methods. The problem is solved using the mass ? failure rate and cost ? failure rate relationships of the spacecraft systems. For the supporting complex, the dimension of the mathematical simulation problem is reduced to two: a formula is derived to find the optimal failure rates of all the systems of the supporting complex using the optimal failure rates of two systems of it. The variables for the special complex and the supporting complex are separated. Due to the fact that each special complex system makes an independent contribution to the overall effect, the problem for the whole spacecraft is reduced to a system of two equations for the special complex and the supporting complex and ncn equations in one variable for the special complex with two coupling variables between the supporting complex and the special complex where ncn is the number of the special complex systems. The paper presents a numerical-and-analytical method for spacecraft system failure rate optimization where the initial guess is specified indirectly: by specifying the supporting complex mass and probability of no-failure operation. The method may be used in the development of a space hardware design methodology accounting for economic factors. From the optimal values of the spacecraft system failure rates found using the mass ? failure rate and cost ? failure rate relationships, one can find the masses and costs of the spacecraft systems to be used in optimizing the parameters and development cost of the systems. The method is expected to increase the profitability and competitiveness of spacecraft under development.
Необхідні умови критичного мислення
Authors: Кулик Олександр
Published: July 2024

Актуальність даного дослідження викликана відсутністю в сучасній науковій літературі консенсусу щодо визначення критичного мислення. Спроби узагальнити наявні дефініції критичного мислення зіштовхуються з тим, що представники різних наукових дисциплін та підходів роблять акцент на відмінних аспектах критичного мислення, часто спираючись при цьому скоріше на інтуїтивні уявлення, ніж на результати обґрунтованого дослідження. Тривають активні дебати не тільки щодо різних аспектів критичного мислення, але і щодо його сутнісних рис.
Мета даного дослідження  полягає в тому, щоб прояснити феномен критичного мислення в контексті наявності його численних та суперечливих визначень. Зокрема, у дослідженні робиться спроба запропонувати альтернативу надто загальним тлумаченням критичного мислення, які, не наводячи в своїх дефініціях конкретики, пропонують вважати критичним мисленням будь-який прояв вдалого мислення. Також при розгляді піднятих питань в цьому дослідженні взято до уваги не тільки концептуальну, але й історичну конкретність терміну «критичне мислення», аналізуючи специфіку появи та розвитку руху критичного мислення. 
Результати дослідження полягають в тому, що завдяки аналізу визначень критичного мислення, у тому числі тих, що були надані у роботах Джона Дьюї, Пітера Фесіона, Роберта Енніса та Джона Макпека, а також в результаті ретельного дослідження самого феномену, який позначають ці дефініції, в статті було визначено необхідні умови критичного мислення. Дослідження виявило, що критичне мислення втілюється в життя завдяки трьом умовам, кожна з яких окремо є необхідною умовою, а всі вони у сукупності є достатньою умовою для даного типу мислення: по-перше, критичне мислення прагне втілити такі характеристики раціональності, як об’єктивність, обґрунтованість, точність та ефективність; по-друге, воно включає в себе метакогнітивний компонент; по-третє, критичне мислення використовує мисленнєві процедури, які доступні широкому колу осіб.
Висновки даного дослідження полягають в тому, що, у порівнянні з альтернативними поглядами, запропоноване у статті розуміння надає чіткі критерії, щоб відрізнити критичне мислення від інших типів мислення. Показано, що результати даного дослідження можуть бути цінними як у дослідницьких, так і в освітніх цілях, зокрема для з’ясування спільності та відмінностей між терміном «критичне мислення» і спорідненими термінами.

O legado hermenêutico do Círculo de Éranos para as Ciências da Religião
Authors: Silva João Victor Sant’Anna , Chaves de Souza Vitor
Published: July 2024

O artigo apresenta histórica e teoricamente o Círculo de Éranos como um modelo interpretativo para as Ciências da Religião. Trata-se, a rigor, de uma aproximação ao mesmo tempo histórica e temática ao Círculo de Éranos buscando as pluralidades nos encontros que pudessem contribuir à uma hermenêutica para as Ciências da Religião. Sabe-se que os encontros, inaugurados por Olga Fröbe-Kapteyn, colocou em conversa variados pensadores de áreas distintas, como Rudolf Otto, Carl Jung, Martin Buber, Paul Tillich, Jakob Hauer, Heinrich Zimmer, Karoly Kerenyi, Gershom Scholem, Henry Corbin e Mircea Eliade. Em uma tentativa incansável de aproximar Ocidente e Oriente, Jung, a título de contextualização, teve a oportunidade de modificar parte de suas teorias devido a convivência com os participantes, atribuindo, assim, uma renovada significação religiosa às suas reflexões. Além de Jung, Mircea Eliade, como um dos principais interlocutores com Jung, também contribuiu a respeito do significado da vida religiosa. Este artigo, portanto, busca recuperar a história do Círculo de Éranos e, ao invés de vasculhar o valor do Círculo de Éranos em si, pretende trabalhar a contribuição do Círculo de Éranos para a constituição da área das Ciências da Religião e Teologia pelo viés da linha de pesquisa Linguagens da Religião propondo uma base hermenêutica da pluralidade a partir de uma reinterpretação do significado da pesquisa em Ciências da Religião tendo no Éranos uma forma de spiritus rector original.
Autoridade religiosa, diversidade e o princípio pluralista
Authors: Ribeiro Claudio de Oliveira
Published: July 2024

O texto apresenta resultados de pesquisa sobre a diversidade no campo religioso brasileiro, analisada sob o princípio pluralista, e como ela incide no debate acerca do exercício da autoridade religiosa. Metodologicamente, os olhares a respeito das experiências religiosas priorizaram interpretá-las a partir dos entrelugares e fronteiras das culturas, dos espaços interstícios e não institucionais de poder e das possibilidades de visibilidade e empoderamento dos grupos subalternos. Com isso, foi possível realçar as formas pelas quais o poder é exercido internamente nos distintos contextos religiosos, considerando as diversas contradições e ambiguidades que possuem. Entre os resultados da pesquisa, estão descrições sobre o quadro do pluralismo religioso brasileiro, com destaque para a visão diversificada sobre autoridade religiosa, levando em conta o contexto plural da sociedade e a diversidade interna das expressões religiosas. Nesse quadro se destacam variados processos de reconfiguração do quadro religioso brasileiro, como o deslocamento do religioso para esferas culturais, o primado das experiências sensoriais no campo religioso, as variações que a diversidade sexual e de gênero trazem para o campo de cada expressão religiosa e as formas de fundamentalismos, ecumenismos, trânsitos e múltiplas participações religiosas. A pesquisa abordou também as fontes que conferem legitimidade à autoridade religiosa, possibilitando o exercício da liderança e da representação: (i) o conhecimento formal ou informal do texto sagrado (no caso das religiões que o possuem); (ii) as formas de sapiência acumuladas no conjunto das experiências de vida; (iii) o carisma que determinadas pessoas ou grupos cultivam e que reforça a capacidade de articulação e mobilização coletiva ou na gerência da vida comunitária ou institucional; e (iv) o status socioeconômico e cultural conferido pelas próprias comunidades ou instituições religiosas ou ainda por setores externos a elas.
A ideologia como imanentização do eschaton: um estudo introdutório da perspectiva de Eric Voegelin
Authors: Teixeira Carlos Flavio , Fransoze Marcelo Souza
Published: July 2024

Existem diversas possibilidades de definição de ideologia, notadas nos âmbitos filosófico, político ou sociológico. Este breve estudo busca apresentar a definição de ideologia proposta por Eric Voegelin e evidenciar como o autor identifica as ideologias políticas modernas com uma imanentização do eschaton cristão. Adotando o método de revisão bibliográfica, recapitula alguns autores que formularam o conceito de ideologia, analisa as abordagens críticas em relação a ideologia, e apresenta o conceito formulado por Voegelin. Em seguida expõe o conceito de transcendência presente na escatologia cristã e finaliza apontando como se excluiu o elemento transcendente, assim criando uma escatologia secular.
Ensino religioso escolar nos votos do STF: a religião como crença
Authors: Montero Paula
Published: July 2024

Este artigo examina os argumentos dos 11 ministros do Supremo Tribunal Federal que, em 2017, decidiram pela constitucionalidade da oferta de ensino confessional na escola pública. Trata-se de analisar como valores éticos e jurídicos em disputa na longa duração se rearticulam nestes votos em torno da noção de crença, passados quase 40 anos da definição do Ensino Religioso como direito humano fundamental pela Constituição. Não se trata de voltar ao tema do secularismo, seja como processo social, seja como norma jurídica ou doutrina política. A análise das formulações discursivas dos votos dos ministros busca, ao contrário, desvendar as diferentes construções do religioso implicadas no uso dos termos religião e direitos e compreender como elas operam na projeção de uma ideia de cidadania e/ou da nação. Pretende-se tornar mais evidente, a partir desse exame sistemático dos votos, a configuração do senso comum jurídico quando se trata de emitir juízos de valor sobre o religioso e sua proteção.

Authors: Balestreri Isabella Carla Rachele
Published: July 2024

The broletto, the medieval building that housed the communal administration of the Lombard cities, has long been the subject of studies that examine it from ethical, political, stylistic, and formal points of view. In recent years, focus in medieval studies has shifted to areas of the ‘margins of the communal world’, territories that, although relevant to historical change, have been neglected by historiography. In this contribution, I consider the architecture of buildings in fringe areas from the valleys in the Rhaetian and Bergamasque Alps that date to the communal age and that were significantly transformed between the 15th century and the early contemporary period. I begin with general remarks about the context and then use the communal palace of Clusone in Bergamo and the Palazzo Pretorio di Chiavenna (Sondrio) as case studies, drawing on unpublished documents in the municipal archives of the two cities.
Communal Spaces and Buildings in the Making: Pistoia’s Piazza del Duomo (14th-18th Centuries)
Authors: Folin Marco
Published: July 2024

This paper deals with the relationship between continuity and change in architectural history, or, to be more precise, with the relationship between the continuity of built structures and the changes in their uses and meanings, using as a case study the Piazza del Duomo in Pistoia. The piazza is a kind of fossil of the communal age, surrounded as it is by the main public buildings of the late medieval city whose physical appearance has not been radically altered over time and whose functions have even remained largely stable. And yet the buildings are at the same time characterized by a history of continuous change, as a result of the Florentine conquest and the loss of political autonomy, as well as the internal evolution of the local ruling class. The paper focuses on these transformations, which adapted the public buildings to functions quite different from those for which they were originally built, all while preserving their external appearance, in order to ideologically exalt the ancient roots of civic identity as the main cornerstone — fictitious but credible — of Pistoia’s urban image.

Authors: Ayhan Gülsen
Published: July 2024

Yavaş şehirlerin benimsenmesiyle yavaş turizm hareketi başlamıştır. Yavaş turizm diğer turizm türlerinden farklılıklar göstermektedir. Yerele özgü, doğayı koruyan ve çevreye duyarlı bir turizm hareketi ile yavaş turizm hareketi sürdürülebilir turizm ile bağdaşmaktadır. Yavaş şehirlerin marka olması ve tanınırlığının artması aynı zamanda turistlerin turizm algılarının doğaya ve yerele özgü şeklinde değişmesi yavaş şehirlerde turizm hareketliliğinin hız kazanmasına sebep olmuştur. Yavaş şehir olmadan ve olduktan sonraki turizm hareketliliğinin ortaya konulması yavaş şehirlerin yavaş turizme etkisinin değerlendirilmesinde etkili bir faktördür. Şehirlerde bulunan tesislere gelen ve konaklayan turist sayılarının ortaya konulması ve bunların zamansal değişimleri yavaş şehirlerdeki turizm hareketliliğinin belirlenmesine katkı sağlamaktadır. Araştırmada Türkiye’nin ilk yavaş şehirlerinden Seferihisar, Gökçeada, Yalvaç ve Perşembe şehirlerinin yavaş şehir olmadan ve olduktan sonraki turizme etkisini değerlendirmek amaçlanmıştır. Bu bağlamda yavaş şehirlerin turizme etkisini belirlemek amacıyla Kültür ve Turizm Bakanlığı’ndan tesislere gelen ve konaklayan sayıları elde edilmiş, veriler işlenmiş, tablo ve grafiklere dönüştürülmüştür. Yavaş şehirlerin yavaş şehir olmadan ve olduktan sonraki turizm verileri karşılaştırılmıştır. Yavaş şehir olduktan sonra tesislere gelen ve konaklayan sayılarında önemli artışlar meydana gelmiştir. Araştırma kapsamındaki yavaş şehirlerin hepsinde konaklayan sayılarında artışlar yaşanmıştır. Bu artışlarda şehirlerde yıllara göre dalgalanmalar söz konusu olsa da genel olarak pandemi sürecinden dolayı 2020-2021 yıllarında azalmalar meydana gelmiş ve 2022-2023 yıllarında tüm şehirlerde konaklamalarda yeniden artışlar olmuştur. Sonuç olarak Türkiye’deki dört yavaş şehir, yavaş turizm hareketini beraberinde getirmiştir.

La anemia, una condición globalmente extendida, muestra una alta prevalencia en países en desarrollo, particularmente en grupos de alto riesgo, siendo los niños menores de cinco años uno de los más afectados. La carencia de un diagnóstico temprano y un tratamiento apropiado puede conllevar al deterioro de las habilidades cognitivas y retrasos en el desarrollo infantil. Objetivo: Investigar y determinar la prevalencia de la anemia en niños menores de cinco años atendidos en el Centro de Salud No. 3. Metodología: Estudio descriptivo y cuantitativo. Este análisis incluyó una muestra de 251 niños, y se rigió por las directrices del Ministerio de Salud Pública (MSP). Resultados: Los resultados revelaron que el 51% presentaba anemia ferropénica leve, el 47% anemia ferropénica moderada, y el 2% anemia ferropénica severa. En cuanto al tratamiento, el 49,3% de los casos de anemia leve recibió hierro polimaltosado, el 46,7% sulfato ferroso, y un 4% no recibió tratamiento. En los casos de anemia moderada, el 49,4% recibió hierro polimaltosado, el 46,15% sulfato ferroso, y el 4,39% no fue tratado. En relación a los casos de anemia severa, el 66,6% recibió hierro polimaltosado, y el 33,4% tratamiento con sulfato ferroso; todos los casos de anemia severa recibieron tratamiento. Conclusión: aproximadamente 2 de cada 10 niños con anemia leve y 1 de cada 10 con anemia moderada no recibieron el tratamiento recomendado, lo que enfatiza la importancia de mejorar la atención y el acceso a tratamientos adecuados en estos casos para asegurar un desarrollo saludable en los niños afectados por esta condición.

Objetivo: Determinar el nivel de burnout y explorar sus correlaciones con factores sociodemográficos en estudiantes de un semestre de enfermería en una universidad de Medellín. Metodología:  Se utilizó un enfoque cuantitativo con un diseño observacional-descriptivo y corte transversal. La selección de la población fue probabilística y no aleatoria, y se aplicó el cuestionario Maslach Burnout Inventory - Student Survey (con un alpha de Cronbach de 0.86) para evaluar el desgaste académico en tres dimensiones. Resultados: La edad promedio de los estudiantes fue 23.25 años siendo un 70% mujeres. Un 40% eran auxiliares y 30% trabajaban. El 45% de los estudiantes puntuaron niveles altos de burnout y el 55% presentaron niveles entre moderado y extremo. A nivel subescala, el 100% mostró puntajes altos de cinismo y 74% puntajes bajos en autoeficacia. No se encontraron correlaciones significativas entre el nivel de burnout y ser auxiliar de enfermería o trabajar. Conclusión: La presente investigación evidenció que la totalidad de los estudiantes experimentaron algún grado de burnout, señalando una preocupante prevalencia en la muestra estudiada. Sin embargo, los análisis no revelaron correlaciones significativas entre el nivel de burnout y la condición de haber cursado estudios auxiliares previos al pregrado o la actividad laboral.

The purpose of the present study is to assess the relationship between digitalization disclosure indicators and market capitalization in the Russian market, including during the COVID-19 pandemic. The research methodology includes text analysis to evaluate various components of digital transformation (business model transformation, process transformation, domain transformation, organization transformation) and digitalization. The model was assessed using panel regression and machine learning methods. The empirical basis of the study included financial indicators of 70 Russian companies and annual reports for 2017–2021. The main results are: 1) wider disclosure of information about digitalization in the annual reports of Russian companies increased company market capitalization; 2) the transformation of processes and organizationswas highly significant for Russian companies; 3) the COVID-19 pandemic accelerated digitalization and led to a partial catch-up in the level of digitalization among less advanced companies. The results of this study can be used by investors and company management to develop more competent and comprehensive digital policies.
