Published: January 2025

This study aims to investigate the role of management in the development of Micro, Small, and Medium Enterprises (MSMEs) in the tourist sector as a catalyst for local economic development in the Lebak District. The study` takes a qualitative methodology, with government agencies and MSME actors in Lebak District serving as research informants. The findings emphasize the importance of effective management techniques in the development and growth of MSMEs operating in tourist attraction regions. Strong government support through local rules, streamlined licensing procedures, and the availability of suitable business locations are all important elements impacting MSME development. However, problems such as limited availability to raw materials, marketing limits, and financial constraints. It is crucial to focus on improving management competencies for the MSME actor in order to handle these difficulties and boost MSME development. This includes assisting with infrastructure development, developing human resource skills, and encouraging collaboration among government agencies, local communities, and MSME actors. Furthermore, the government should make the finance more accessible and provide business training programs to empower MSMEs in the tourism sector and drive local economic growth in the Lebak District. Effective management practices are critical for guaranteeing MSMEs' long-term viability and competitiveness in the fast-paced tourist business.

Published: January 2025

This study aims to examine the role of Career Adaptability and Career Development in enhancing employee performance within the context of higher education transformation. Research focusing on organizations undergoing continuous change remains limited. Change management is a critical issue for such organizations. Universitas Negeri Semarang (UNNES), as an example of higher education undergoing structural transformation into a Legal Entity State University (PTN-BH), serves as the context for this study. Specifically, this research explores the impact of career adaptability on employee performance at UNNES. Currently, there is a lack of research on career development that specifically focuses on higher education institutions transitioning to PTN-BH. Key issues addressed in this study include career dynamics within continuously evolving organizations. The research adopts a quantitative approach with a causal design. The sampling technique in this study is using random sampling where sampling is done randomly regardless of the strata in the population. The sample of this study amounted to 138 people (20%) of all employees of Universitas Negeri Semarang. In this study, surveys were used as a method of data collection. Data analysis techniques in this study used descriptive and statistical methods. The findings of this study indicate that the factor that plays a role in influencing employee performance at Universitas Negeri Semarang is career adaptability. Meanwhile, career development does not influence employee performance. Meanwhile, career adaptability and career development together have a significant impact on performance. Thus, employee adaptability with a comfortable work environment designed to build trust between employees, share knowledge and skills to support continuous learning and improve employee performance is needed.

Представлены результаты комплексного изучения ледового комплекса, вскрытого в пределах цокольно-аккумулятивной террасы в нижнем течении реки Вилюй. На основании химических, изотопных, гранулометрических, палинологических и радиоуглеродных данных установлено, что формирование ледового комплекса происходило с конца каргинской (МИС-3) и на протяжении сартанской (МИС-2) эпох позднего неоплейстоцена (от 29.0 до 11.7 тысяч лет назад) в криоаридных условиях, когда преобладали ландшафты сухих холодных степей с доминированием ксерофитных сообществ, местами разнотравно-злаковых лугов. Низкая минерализация сингенетических повторно-жильных льдов (0.07-0.29 г/дм3), преобладание гидрокарбоната кальция в химическом составе свидетельствуют, что основным источником формирования жил являлись зимние атмосферные осадки - талая снеговая вода. Повышенное содержание тяжелых металлов (Fe, Mn, Co, V, Sr) указывает на то, что в формировании льдов участвовали также воды мелких промерзающих озер, приуроченных к полигональному рельефу. Отмечен относительно легкий изотопный состав льдов (d18О -(29.2 ± 0.3) и -(27.2 ± 1.4) ‰, dD -(226.6 ± 2.3) и -(215.8±8.5) ‰, dexc (6.8 ± 0.51) и (1.7 ± 3.1) ‰), который схож с составом современных атмосферных осадков холодного сезона г. Якутска и весеннего снегозапаса. Такой изотопный состав свидетельствует о сухих и холодных условиях при формировании повторно-жильных льдов исследуемого участка.
This article presents the results of a comprehensive investigation of the ice complex discovered within the strath terrace in the lower course of the Vilyui River, Central Yakutia. On the basis of chemical, isotopic, granulometric, palynological, and radiocarbon data, it has been revealed that the formation of the ice complex took place from the end of the Kargin (MIS-3) and throughout the Sartan (MIS-2) epochs of the Late Pleistocene (between 29 and 11.7 ka BP) under cryoarid conditions with a predominance of dry cold xerophytic steppes and, locally, forb-grass meadows. Mineralization of syngenetic ice wedges is low (0.07-0.29 g/dm3), and a predominance of calcium bicarbonates suggests that winter precipitation - snowmelt water - was the main source of wedge ice. The increased content of heavy metals (Fe, Mn, Co, V, Sr) indicates that the formation of ice wedges also involved the water of shallow freezing lakes confined to the polygonal microrelief. The ice wedges have a relatively light isotopic composition ( 18О -(29.2 ± 0.3)‰ and -(27.2 ± 1.4)‰; D -(226.6 ± 2.3)‰ and -(215.8 ± 8.5)‰, dexc (6.8±0.51)‰ and (1.7±3.1)‰), which is close to the composition of modern atmospheric precipitation of the cold season and spring snow storage in Yakutsk. These data attest to dry and cold conditions, thin snow cover, and moisture deficiency in cryogenic landscapes during the formation of the ice complex.

Приведены результаты исследования, проведенного на геокриологическом стационаре “Туймаада” в Центральной Якутии. Проанализирована связь испарения с поверхности почв с жидкими осадками за теплый период 2015-2016 и 2019 гг. и изучен их химический состав. Средняя величина испарения, которая превысила количество осадков примерно на 40 %, составила 1.37 (0.33-3.13) мм/сут. Интенсивность испарения особенно велика в мае, что связано с оттаиванием мерзлых пород и просачиванием снеговой воды в сезонноталый слой. Химический состав атмосферных осадков в течение лета остается стабильным гидрокарбонатно-кальциевым, но минерализация понижается к осени на 20-40 %. Содержание большинства химических элементов меняется со временем, максимум приходится на май-июнь. Наибольшая контрастность для хлоридов, сульфатов, натрия и аммония характерна в периоды максимального и минимального испарения с поверхности почв.
The results of a study of the relationship between evaporation from the soil surface and atmospheric precipitation during the warm seasons of 2015-2016 and 2019 at the Tyimaada geocryological research station in Central Yakutia are analyzed. The volumes of evaporation from the soil surface and precipitation›s amount and chemical composition were studied. The average evaporation was 1.37 (0.33-3.13) mm/day, exceeding precipitation by about 40%. The intensity of evaporation was especially high in the first month of the warm season (May), which was associated with the thawing of frozen soil and the seepage of meltwater from snow into the seasonally thawed layer. The bicarbonate calcium chemical composition of atmospheric precipitation during the summer remained stable, but the degree of mineralization decreased by 20-40% by autumn. The content of most chemical elements in precipitation was higher in May-June and decreased in the second half of the warm season. The greatest contrasts in the concentrations of chlorides, sulfates, sodium, and ammonium in the atmospheric precipitation were observed during the periods of maximum and minimum evaporation from the soil surface.
ПРИМЕНЕНИЕ ЛАНДШАФТНЫХ ИНДИКАТОРОВ ГЕОКРИОЛОГИЧЕСКИХ УСЛОВИЙ ПРИ ИНТЕРПРЕТАЦИИ ДАННЫХ ГЕОЭЛЕКТРИКИ

Обосновано использование фито- и биоиндикаторов для интерпретации данных геоэлектрики при изучении мерзлотных разрезов. Исследования проводились с помощью методов электротомографии и георадиолокации в разных климатических и геокриологических условиях от Тянь-Шаня до Магаданской области. В каждом районе были выделены свои ландшафтные признаки геокриологических условий и сопоставлены с геоэлектрическими разрезами или данными георадиолокации. Показано, что в Центральной Якутии определенные виды лиственниц, а в Забайкалье берез в сочетании с высоким сопротивлением пород указывают на наличие мерзлых пород с пониженной температурой. На территории Северо-Востока России тополя и чозении растут в области развития таликовых зон, что дает основание интерпретировать участки низкого электрического сопротивления пород под ними как талики, а не как пиритизацию или повышенную глинистость. В Тянь-Шане установлена корреляционная связь электрического сопротивления каменного глетчера и его возраста, на который указывает размер лишайника рода Rhizocarpon sp. В условиях горной местности аномалии низкого сопротивления в местах скопления крупных гнезд муравьев означают глубокое залегание кровли мерзлых пород или наличие сквозных таликов в разломных зонах. Учет ландшафтных индикаторов геокриологических условий позволяет уменьшить неоднозначность геологической интерпретации данных геоэлектрики.
The use of phyto- and bioindicators for interpreting geoelectric data in the study of permafrost sections is substantiated. The research used electrical resistivity tomography and ground-penetrating radar methods in various climatic and geocryological conditions from the Tien Shan to the Magadan region. In each region, specific landscape features of geocryological conditions were identified and compared with geoelectric sections or ground-penetrating radar data. Certain types of larch stands in Central Yakutia and birch stands in Transbaikalia together with data on high rock resistivity indicate the presence of permafrost with reduced temperature. In the northeast of Russia, poplars and willows (chosenia) grow in the area of talik zones, which allows interpreting areas of low electrical resistivity of rocks under them as taliks rather than the areas with pyritization or increased clay content. In the Tien Shan, a correlation was established between the electrical resistivity of a rock glacier and its age indicated by the size of Rhizocarpon sp. lichens. In mountainous areas, anomalies of low resistivity in places, where large anthills are concentrated, indicate the deep occurrence of permafrost table or open taliks in fault zones. Thus, taking into account landscape indicators of geocryological conditions helps us to reduce the ambiguity of geological interpretation of geoelectric data.

Published: January 2025

Introduction: Medical students are at high risk of developing risk factors for mental disorders.
Objectives: To determine the prevalence of symptoms of anxiety and depression among second year medical students of a university in São Paulo, Brazil, and to identify their reasons for seeking mental health services.
Materials and methods: Cross-sectional mixed-methods study conducted in 74 second year medical students, who completed an online survey that included an ad hoc questionnaire, the validated versions for Brazilian population of the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI), and open-ended questions about the reasons for seeking and using the mental health services offered by the medical school and their motivation to continue with their medical training. A qualitative analysis of the responses to the open-ended questions was performed.
Results: Mean scores in the Trait-Anxiety and State-Anxiety scales were 47.52 and 48.17 (moderate anxiety), while the mean score in the BDI was 11.67 (mild depression). Transgender students and those who were beneficiary of a quota system or social and/or economic support program had higher scores in the State-Anxiety scale (53.00 and 49.32 points; high anxiety) and in the BDI (12.00 and 13.99). Furthermore, 36.48% of the students had used the mental health services offered by the school of medicine and 85.13% reported having sought emotional support from friends and the medical school. Answers to the open-ended questions revealed that the main reasons that led students to seek the school’s mental health service were anxiety, depression, stress, and attention deficit.
Conclusion: In the present study, second year medical students had mild depression symptoms, as well as moderate levels of State and Trait anxiety. In addition, the main reasons for seeking and using the mental health services offered by the medical school were anxiety, depression stress, and academic orientation (attention deficit).

Published: January 2025

Introducción. Las anomalías congénitas (AC) tienen un impacto significativo en la salud y la calidad de vida. Por tanto, conocer su prevalencia y los factores asociados a su desarrollo es esencial para diseñar e implementar programas educativos y preventivos.
Objetivos. Determinar la prevalencia de AC en un hospital de referencia nacional de Ecuador entre 2009 y 2022 y explorar los factores asociados a su presencia.
Materiales y métodos. Estudio transversal realizado con 2 conjuntos de datos para el periodo 2009 y 2022: 105 385 nacidos vivos dados a luz en el HGOIA (estimación de la prevalencia) y 26 236 neonatos hospitalizados en el servicio de neonatología del hospital (exploración de factores asociados a la presencia de AC). Se usó la prueba de Chi cuadrado para evaluar diferencias entre grupos (recién nacidos con y sin defectos congénitos). Además, se usaron modelos de regresión logística binaria, tanto simple (Odds ratio [OR] brutos) como múltiple (OR ajustados) para evaluar las asociaciones entre las condiciones perinatales consideradas y la presencia de AC (en general y por categoría de anomalía).
Resultados. La prevalencia de AC fue 2.92% (n=3 075). Las anomalías del sistema nervioso (25.6%), de los sistemas cardiovascular y respiratorio (21.1%) y musculoesqueléticas (16.1%) fueron las AC más frecuentes. La edad materna >35 años (OR: 1.20, IC95%: 1.07-1.33) se asoció positivamente con la presencia de AC, mientras que el embarazo planificado (OR: 0.88, IC95%: 0.81-0.96) y el embarazo múltiple (OR: 0.50, IC95%: 0.42-0.60) se asociaron negativamente. El consumo de ácido fólico, ser varón y varios factores relacionados con la madre, entre otras variables, mostraron una asociación con la presencia de tipos específicos de AC.
Conclusiones. La prevalencia de AC en el HGOIA entre 2009 y 2022 es ligeramente superior a la reportada en la región, siendo las anomalías del sistema nervioso y las de los sistemas cardiovascular y respiratorio las más frecuentes. Se encontró una asociación positiva entre la edad materna >35 años y la presencia de AC, mientras que la planificación del embarazo y los embarazos múltiples mostraron asociaciones negativas.
Expropriações contemporâneas: reflexões sobre a situação trágica do povo Yanomami no Brasil
Authors: Claudino Guimarães Karoline , Martins Pinheiro Silvia Silva 
Published: January 2025

Este artigo tem como objetivo principal analisar criticamente, a partir de uma perspectiva marxista, os processos expropriatórios contemporâneos, considerado como uma de suas expressões mais nítidas e brutais na atualidade a situação dos povos Yanomami. Tal cenário envolve não apenas a dinâmica capitalista no contexto de crise, mas também o acirramento da política neoliberal no Brasil, a qual, nos últimos anos tem refletido no aumento e na aceleração das expropriações. Esse aprofundamento tem impactado direta e indiretamente as condições de vida e de subsistência não apenas da classe trabalhadora, mas, ainda, dos povos originários, que seguem padecendo, sobretudo, devido ao avanço dos garimpos ilegais em territórios indígenas, da falta de políticas públicas e da degradação e destruição do meio ambiente.
La nominalización del “científico” y “científica” durante la Revolución Científica
Authors: Laris Pardo Jorge Alejandro 
Published: January 2025

En la historiografía de la ciencia actual, que está fuertemente influenciada por corrientes anglosajonas, se ha vuelto obligatorio señalar que William Whewell (1794-1866) acuñó en 1834 la palabra “scientist” en inglés, debido a la dificultad de encontrar una voz equivalente al alemán “natur-forscher”. El propósito de este documento es cuestionar si es correcto aplicar esta reflexión para la evolución de la palabra “científico” o “científica”. Con ello en mente, se sustenta el estudio de la nominalización de esta palabra en el español. Se estudian fuentes históricas con el auxilio de herramientas digitales como el Corpus del Diccionario histórico de la lengua española (CDH), el Corpus Diacrónico del español (CORDE) y el Nuevo Tesoro Lexicográfico de la Lengua Española (NTLLE) de la Real Academia de la Lengua Española; el Diccionario de la Ciencia y de la Técnica del Renacimiento de la Universidad de Salamanca; así como la base de datos de Google Ngram. Estas búsquedas se han complementado con testimonios que el autor ha recabado a lo largo de sus investigaciones y un diálogo con la historiografía pertinente. Se concluye que la evolución de nuestra palabra “científica” o “científica” no corresponde a la anglosajona. Por el contrario, su origen se encuentra en un largo proceso de nominalización.
Investigating the mechanical performance of innovative bean pod ash particulates reinforced in AA6063 alloy for construction and building applications
Authors: Ben Festus , Olubambi Peter Apata 
Published: January 2025

Abstract
The AA6063, renowned for its corrosion resistance, faces limitations in construction and building applications due to its low mechanical strength. Bean pod ash (BPAp), a byproduct of the agro-waste heat-treatment process, presents an innovative and sustainable alternative to synthetic reinforcements. This study aims to improve the mechanical properties of AA6063 by incorporating BPAp and a hybrid of BPAp and alumina. Four aluminum matrix composites (AMCs), including unreinforced AA6063, were fabricated using a two-step stir-casting process with 10 wt.% BPAp and alumina in varying weight ratios. The microstructure, porosity, hardness, tensile strength, Young’s modulus, and ductility of the AMCs were evaluated. SEM analysis showed uniform BPAp dispersion and porosity below 4%, indicating lightweight AMCs. The composites exhibited enhanced mechanical properties, showing increased hardness (74.70-to-105.04 BHN), tensile strength (118.87-to-207.49 MPa), ductility (5.00-to-12.22%), and Young’s modulus (13.25-to-15.63 GPa). These findings demonstrate that BPAp effectively enhances AA6063 and offers a cost-effective, eco-friendly reinforcement solution.

Background:
Arteriovenous (AV) fistulas are the preferred access for dialysis but have a high incidence of failure. This study aims to understand the crosstalk between skeletal muscle catabolism and AV fistula maturation failure.

Methods:
Skeletal muscle metabolism and AV fistula maturation were evaluated in mice with chronic kidney disease (CKD). The roles of myostatin and YAP1 in regulating the transdifferentiation of adventitial mesenchymal stem cells (mesenchymal stem cells) and intima hyperplasia in AV fistula were investigated. Nanoparticles carrying a YAP1 inhibitor, verteporfin, with light irradiation-controlled release were synthesized and applied to AV fistula.

Results:
Increased trichrome signals and stenosis were observed in AV fistulas from mice treated with myostatin and from mice with CKD. In contrast, blocking myostatin function with an anti-myostatin peptibody not only improved body weight and muscle size in CKD mice but also decreased neointima formation in AV fistulas. In cultured mesenchymal stem cells, myostatin induced YAP1 expression, promoting the differentiation of mesenchymal stem cells into myofibroblasts and inducing extracellular matrix deposition. Red light irradiation-controlled release of verteporfin from nanoparticles blocked YAP1 activation and alleviated myostatin-induced mesenchymal stem cell activation. Periadventitial application and red-light irradiation of nanoparticles carrying verteporfin significantly suppressed stiffening and neointima formation in AV fistula.

Conclusions:
CKD induced muscle wasting leading to increased production of myostatin, which stimulated mesenchymal stem cell activation and vascular fibrosis linked to AV fistula stenosis. YAP1 signaling was activated in these processes. Red-light irradiation-controlled release of verteporfin offered a feasible approach for local vascular drug intervention to improve AV fistula maturation.
