Published: February 2025

This study focuses on Kim Hyeong-bok, a reporter for the Korean version of the Chosun Shinmun , as a journalist who cooperated with Japan’s rule of Chosun. I tracked down the pen name reporter ‘Geumdangsaeng’ in the Korean version of Chosun Shinmun and found out that he was Kim Hyeongbok, a journalist who worked at Sisa Newspaper and Gando Daily Newspaper in the 1920s and 1930s. This study analyzed Kim Hyeong-bok’s articles in the Korean version of the Chosun Shinmun and found that his starting point as a collaborative journalist was his activities as a reporter for the Korean version of the Chosun Shinmun. As a result of analyzing Present Chosun and Argument against abolition of Chinese Characters published by Kim Hyeongbok in 1917, it was found that the publication plan originated from the reporter’s activities for the Korean version of the Chosun Shinmun. Choi Chan-sik, who had a close relationship with Kim Hyeong-bok, disseminated ‘Self-Help’ through literature in the Korean version of the Chosun Shinmun . This study will be helpful in identifying the personal networks of intellectuals who accepted the ‘Self-Help’ in the 1910s.

Published: February 2025

The First Squad of the Korean Volunteer Army, was expanded to two independent squad, which were respectively sent to 'Enemy occupied territory of “Huabei” and “Huazhong”. The headquarters of KVA aimed to maintain a balance between the tasks of Korean National Movements and the tasks of the Chinese National Revolution by distributing the newly established forward units across the southern and northern fronts and assigning them with different missions. However, this strategic deployment plan was altered due to fluctuations in the local battlefields situation and the mobilization plan by the Chinese authorities. As a result, the newly established forward units were dispersed into “Huabei”, “Huazhong” and “Huanan”. Nevertheless, the headquarters continued to make sustained efforts to implement the tasks of the Korean national movement and attempted to adjust the operational zones of each forward unit. This Change in the operational zones of the newly established units serves as a significant indicator of the internal shift in the activities and direction of Korean Volunteers Army.

Published: February 2025

De acordo com o relatório do Painel Intergovernamental sobre Mudanças Climáticas (IPCC -2021), é inequívoco que a influência humana aqueceu a atmosfera, o oceano e a
terra. Mudanças rápidas e generalizadas na atmosfera, oceano, criosfera e biosfera ocorreram, como resultado das emissões de gases do efeito estufa, levando à necessidade de se estabelecer uma meta de alcançar emissões líquidas zero para dióxido de carbono (CO2). Este trabalho aborda as técnicas atuais e as em desenvolvimento para mitigar as
emissões de CO2 de fontes estacionárias que, embora não sejam as principais fontes de emissão, contribuem para o efeito estufa. São abordadas as técnicas de combustão
(pré, oxi e pós) identificando suas vantagens e considerações, bem como as técnicas de captura mais utilizadas relativas a absorção, adsorção e membranas. Nos processos de
adsorção, discutem-se as configurações de operação e os adsorventes; nos processos de absorção, são abordados, além dos processos, os líquidos absorventes, enquanto
que as discussões sobre as membranas recaem sobre os materiais mais utilizados e em desenvolvimento. Estimativas levantadas pelo Financial Times mostram que tecnologias
como a captura e armazenagem de carbono diretamente na fonte de emissão, consideradas imprescindíveis para descarbonizar indústrias intensivas, hoje custam entre € 90 e € 120 por tonelada. Este valor, associado à taxa de captura / remoção de CO2 de cada processo, e ao custo para implementação das tecnologias discutidas neste artigo,podem contribuir para a definição de melhor processo a ser implementado.

CORPO E TRABALHO CORPORAL EM GESTALT-TERAPIA: DELINEAMENTOS CONCEITUAIS
Authors: Ribeiro Eline Cristiane Rodrigues , Souza Sheron Dayane Vilela de
Published: February 2025

Há muito tempo, o corpo vem sendo objeto de estudo da ciência, assim, filósofos da antiguidade já versavam acerca dessa unidade. Porém, mais que um conceito meramente teórico, mediado por palavras, para Gestalt-terapia o corpo é fenomenológico, à medida emque confere significado ao mundo. Dado seu caráter, não é um fenômeno fixo e acabado, mas em constante reconstrução, assim, ao falar sobre as conceituações de corpo neste trabalho, partimos desse pressuposto, do corpo como algo inacabado e em movimento. Por meio dessa revisão bibliográfica, buscou-se compreender a construção do conceito de corpo e trabalho corporal mediante as percepções e narrativas teóricas dos seguintes autores da Gestalt-terapia: James I. Kepner, Ruella Frank, Laura Perls, Mônica Botelho Alvim, Serge Ginger e Frederick Perls. Percebeu-se que a ênfase no corpo na Gestalt-terapia ainda é uma lacuna a ser preenchida, apesar disso, entende-se que a comunicação corporal do cliente se apresenta como um sistema inteligente de expressões, ondeé revelado sua autenticidade, por isso, deve ser valorizado no setting terapêutico.

Evolution of the Mineralocorticoid Receptor and Gender Difference in Cardiovascular Pathology
Authors: Alessandro Zuccalà
Published: February 2025

Retracing the evolution of Mineralocorticoid Receptors (MR) obliges us to take an instructive as well as fascinating leap back in time. This journey teaches us that the relationship between MRs and what we consider their natural ligand, aldosterone, has not always been an exclusive one. MRs operated for a very long time in the oceans and, in any case, in an aquatic environment, stimulated by ligands other than aldosterone, and exercising functions that we still do not know well but which were certainly different from those they currently perform in terrestrial vertebrates, where they maintain normal sodium and body fluids. The history of MRs was initially intertwined with that of female sexual hormones, in particular with progesterone, which was one of the first agonists for MRs, before becoming, with the transition to the terrestrial environment, an important antagonist. This initial intertwining could be the cause of the sexual dimorphism that can be glimpsed when these receptors are overstimulated, as emerges from many experimental studies and some clinical data and/or when antagonistic drugs for these receptors are studied. This must be taken into account in the planning of clinical studies, especially randomized controlled trials, in which the presence of the two sexes must always be well balanced and in the interpretation of the results which must always be performed being well aware of the gender of participants. This does not always happen, however.

Authors: IKOGHO, Doris Eseoghene
Published: February 2025

The Nigerian educational system faces persistent challenges, including inadequate infrastructure, socio-economic disparities, and cultural barriers, which impede holistic child development. The Child-Friendly School Initiative (CFSI), championed by UNICEF, offers a transformative approach emphasizing inclusivity, safety, health literacy, and participatory governance. This study evaluates the effectiveness of CFSI in Delta State, Nigeria, by comparing CFSI and non-CFSI schools across three dimensions: emotional health, health literacy, and community cohesion.

Using a descriptive survey design, data were collected from 1,229 participants, including pupils, teachers, and community leaders. Instruments were adapted from UNICEF’s evaluation framework, achieving reliability scores of 0.77 to 0.87. Statistical analyses, including Chi-square and ANOVA, were conducted at a significance level of 0.05. Results revealed that CFSI schools significantly outperformed non-CFSI schools in promoting emotional resilience (p < 0.01), implementing health education curricula (p < 0.01), and fostering community cohesion (p < 0.01).

The findings underscore the critical role of CFSI in addressing health disparities, reducing absenteeism, and enhancing social integration. Barriers such as resource limitations, cultural resistance, and insufficient teacher training were identified as constraints to scaling up CFSI. Recommendations include targeted interventions to expand CFSI across Nigeria, addressing funding gaps, promoting community ownership, and integrating health literacy into educational frameworks. This study contributes to the discourse on sustainable educational reforms, aligning with the Sustainable Development Goals (SDGs) on quality education, health, and reduced inequalities.

Antioxidant activity and phytochemical profiling of peaches, Arabica coffee, and their combination
Authors: Putri Dhea Angela , Marsiati Himmi
Published: February 2025

Antioxidant compounds scavenge unstable free radical reactions and are abundant in certain plants. Peaches (Prunus persica L.) are rich in phytochemicals such as carotenoids, anthocyanins, phenolic acids, and flavonoids, while Arabica coffee (Coffea arabica) contains alkaloids, flavonoids, tannins, steroids, and terpenoids. This study evaluated the antioxidant activity and phytochemical profile of peaches, Arabica coffee, and their combination using ethanol, ethyl acetate, and water as solvents. Extraction was performed via maceration with 96% ethanol and fractionation using water and ethyl acetate. Antioxidant activity was assessed using the DPPH (1,1-Diphenyl-2-picrylhydrazyl) assay, and phytochemical tests evaluated secondary metabolites such as alkaloids, flavonoids, phenolics, steroids/terpenoids, tannins, and saponins. Results indicated that the ethyl acetate extract of peaches showed moderate antioxidant activity (IC50 = 141.91 ppm), while the water extract of Arabica coffee exhibited robust activity (IC50 = 22.30 ppm). Notably, combining water extracts from both sources demonstrated enhanced antioxidant capacity (IC50 = 37.85 ppm), improving peach extract activity by over threefold. These findings underscore the potential synergistic effects of combining these natural sources for health-promoting antioxidants.

Published: February 2025

Pemberian Makanan Tambahan (PMT), a supplementary food program using local ingredients, is a targeted intervention to address toddler malnutrition and weight faltering in Indonesia. Despite its widespread implementation, the long-term efficacy of the 14-day PMT program in sustaining growth recovery remains to be determined. This study aimed to evaluate the impact of a 14-day PMT intervention on weight gain and growth stability in children aged 6–59 months experiencing weight faltering. A prospective cohort study was conducted from May to August 2024 at Primary Health Center (Puskesmas) Ajibarang 1 in Banyumas, Central Java, Indonesia. The intervention consisted of 11 snacks and 3 main meals to meet 30–50% of daily caloric needs. Anthropometric measurements, including body weight (BW) and mid-upper arm circumference (MUAC), were collected pre- and post-intervention. 120 children participated, with baseline averages of 11.2 ± 1.5 kg for BW and 13.4 ± 1.7 cm for MUAC. Significant improvements were observed post-intervention, with averages of 12.9 ± 1.2 kg (BW) and 15.0 ± 1.4 cm (MUAC). A moderate positive correlation was identified between BW gain and MUAC (Spearman analysis). In conclusion, the PMT program effectively improves BW and MUAC in children at risk of growth faltering, highlighting its potential as a scalable intervention. These findings emphasize the importance of tailored nutritional programs during early childhood, a critical period for ensuring long-term health and developmental benefits. Advocacy and policy reforms are essential to support consistent implementation and global accessibility of nutritional interventions.
Por que as línguas mudam? Por que variamos?
Authors: Melo Lucas Santos Silva de
Published: February 2025

A mudança e a variação linguística são fenômenos complexos que atravessam todas as línguas naturais, refletindo dinâmicas sociais, históricas e cognitivas. Este artigo apresenta os fatores subjacentes a esses processos, com o objetivo de explorar conceitos consolidados sobre a mudança e a variação linguística, examinando como os indivíduos diferem em suas formas de falar. Nosso objetivo é revisitar as contribuições da Sociolinguística, com ênfase no constructo de Variação e Mudança Linguística, conforme proposto por Weinreich, Labov e Herzog (2006), e explorar como essa abordagem dialoga com outras correntes linguísticas, como o Estruturalismo, o Gerativismo, o Funcionalismo e a Linguística Cognitiva. Nesse contexto, também discutimos os níveis de apreciação e avaliação social dos fenômenos linguísticos (Labov, 2008[1972]) e o contínuo de urbanização apresentado por Bortoni-Ricardo (2004). Além disso, examinamos como as formas linguísticas se entrelaçam às dinâmicas sociais na escolha dos fenômenos da fala, evidenciando como essas escolhas são indexadas às estruturas sociais e culturais que permeiam o processo de variação linguística.

An algorithm for assessing the quality of an FSK signal has been developed, based on minimizing the square of the difference between the measured and reference signals with respect to distortion parameters. It is shown that the algorithm allows for the determination of such FSK signal parameters as carrier offset, deviation error, and carrier frequency drift. The process of vector analysis is studied, including preprocessing, demodulation, signal recovery, and correction. The algorithm’s performance is considered for both pure FSK signals and GFSK signals, as well as FSK with Gaussian filtering.

The geodynamic GNSS (Global Navigation Satellite System) network installed in the south of the island made it possible to estimate secular vertical movements of the earth's surface based on interseismic velocities in the International Terrestrial Reference Frame. The interseismic vertical movements of neotectonic structures were determined from the data of 29 GNSS observation points where 3 to 6 periodic measurement cycles were completed from 1999 to 2012. A characteristic feature of interseismic movements of the earth's surface is the uplift of the entire Yuzhno-Sakhalinsk neotectonic region at an average rate of 1.1 mm/yr, which is in the agreement with the geological and geomorphological studies of the neotectonic evolution of Sakhalin. The highest velocities (1.0–1.6 mm /yr) are confined to uplifts, relatively lower velocities (0.6–0.7 mm/yr) occur in troughs. The revealed inhomogeneities of vertical velocities in the troughs are reflected in the regional field of horizontal deformations and kinematics of faults bounding the troughs. The obtained estimates of the secular neotectonic rates do not agree with the Map of recent vertical movements of the earth's crust of the Sakhalin Island (hereinafter referred to as the RVMEC Map) compiled in the late 1970s. Its geodetic justification was based on the lines of repeated high-precision leveling and the data of sea level observation posts. According to the RVMEC Map, the Yuzhno-Sakhalinsk neotectonic region, as a whole, was characterized by the subsidence of the earth's surface at rates up to 7–8 mm/yr both within the neotectonic uplifts and the troughs and were interpreted as secular tectonic movements. Strong seismic events that occurred during the period of repeated leveling (1959–1977) distorted the RVMEC Map as a map of secular tectonic movements in southern Sakhalin.

The increasing demand for a robust science, technology, engineering, and mathematics (STEM) workforce highlights the need to understand factors that enhance student success in STEM fields. Despite significant need for STEM-qualified individuals, less than half of students initially expressing STEM interest upon college entry graduate with a STEM degree, dropping lower for underrepresented students. The Learning Assistant (LA) program, implemented at colleges around the world, involves students (LAs) aiding their peers through evidence based collaborative activities in STEM courses. It has been well documented that LAs are associated with short-term student success (lower course failure rates) and long-term student success (higher graduation rates). In this study we investigate the impact of the LA program on student success in introductory STEM courses. We analyzed over 10 years of student data, focusing on DFW (D, F, or withdraw) and six-year graduation rates. Using logistic regression and hierarchical linear models, we assessed the influence of LA support on student outcomes, with particular attention to marginalized demographics and repeated LA exposure. We show that LA-supported students in introductory physics courses experienced a 7% decrease in DFW rates. Notably, underrepresented students saw a 10% reduction in DFW rates. Additionally, repeated LA exposure in physics courses provided greater benefits for DFW rates compared to single-course exposure. This research underscores the importance of LA programs in improving STEM education outcomes, notably for underrepresented students.
STEM in chemistry

The development of students' problem-solving skills is vital for cultivating a future-ready workforce, particularly in the domains of Science, Technology, Engineering, and Mathematics (STEM) education. Despite its importance, many students face difficulties in connecting classroom learning to real-world contexts, a challenge that is particularly pronounced in chemistry due to the abstract nature of concepts such as the three levels of chemistry representation (macroscopic, microscopic, and symbolic). The integration of STEM principles into teaching approaches, such as the blended problem-based learning (BPBL) approach, which combines face-to-face and online learning, has shown promise in bridging this gap. By incorporating elements of STEM into the BPBL approach, this study explores how these disciplines can enhance problem-solving skills and facilitate deeper understanding. Specifically, this research investigates the effect of the BPBL_S Module—a module that integrates BPBL with the Socratic method—on students' problem-solving abilities in the three representation levels of chemistry concept. Employing a design and development research approach, the study involved 25 students and one teacher, selected through clustered random sampling. Data were collected through observations, student documents, and interviews, and were analysed thematically. The findings suggest that the BPBL_S Module significantly improves students' problem-solving skills by enabling them to apply STEM concepts to chemistry, thus enhancing their ability to justify solutions comprehensively across macroscopic, microscopic, and symbolic levels. This study underscores the potential of the BPBL_S Module as an effective STEM-based teaching aid to better prepare students for the problem-solving demands of the future workforce.

Due to the growing number of elderly and senile people in the world population, there is an increase in the prevalence of neurodegenerative diseases. Alzheimer’s, Parkinson’s, multiple sclerosis, amyotrophic lateral sclerosis are the most common nosologies in this group, which are based on neuronal damage and subsequent death of the corresponding parts of the brain and spinal cord. These patients are characterized by a growing deficit in daily activities, a decrease in the productivity of cognitive functions, followed by the need for constant and long-term care, which is associated with huge economic and social costs to society. At the same time, there are no effective programs for the prevention and treatment of these diseases. In the review of the literature, the authors analyzed the works devoted to neurodegenerative diseases, the role of nutrition, epigenetics as factors in the prevention and slowing down the progression of neurodegeneration processes.

Published: February 2025

Metabolic syndrome is currently the leading cause of the development of cardiovascular pathology.This is associated with an increase in the prevalence of overweight and obesity, which leads to a significant increase in related metabolic diseases. The production activities of workers in many railway professions, primarily locomotive crew workers, are characterized by high psychoemotional stress, which is an important risk factor for the development of metabolic syndrome. Objective: to establish an association between the prevalence of metabolic syndrome Materials and methods: 220 men have been included into the research, workers of railway transportation with arterial hypertension. All the men have been divided into two groups according to their profession. The first group consisted of 114 workers of locomotive brigades (engine drivers and their Assistants). 106 workers of a railway transportation of other specialties have been included in II group. General clinical part of the study included: collection of complaints, medical history, work experience and duration of the disease, examination, anthropometric data with determination of body mass index, waist circumference. Laboratory tests included assessment of biochemical parameters (total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglycerides (TG), glucose, fasting blood sugar and 2 hours after meals). Results: The frequency of metabolic syndrome is 37% and 35%, respectively, in the first and second groups. Significant differences were found in the prevalence of abdominal obesity: among workers of locomotive crews, abdominal obesity was significantly more common by 14% than among engineers (office workers) (χ² = 8.42; p = 0.004). Among men of working age, workers in stressful professions (machinists and their Assistants) more often have a combination of three components of MS: hypertension with AO and an increase in the concentration of LDL-C >3 mmol/l. The following clusters of metabolic syndrome are more often observed in office workers (engineers): hypertension with AO and hypertriglyceridemia and hypertension with AO and hyperglycemia. Conclusions: The received results specify in necessity of carrying out of primary preventive maintenance arterial hypertension among workers of locomotive brigades.
