VIDA, TRABALHO E PAPÉIS SOCIOESPACIAIS DAS MULHERES A PARTIR DA MIGRAÇÃO RURAL-URBANA NO MUNICÍPIO DE MUZAMBINHO-MG
Authors: Almeida Araújo Letícia , Do Vale Ana Rute
Published: January 2025

Quando vivem no campo, geralmente, as mulheres não possuem o reconhecimento e valorização de seu trabalho, sendo que seus papéis socioespaciais ficam restritos à esfera reprodutiva do lar e acabam buscando, na cidade, uma situação diferente. A partir do caso das mulheres que viveram no campo e depois migraram para a cidade, no município de Muzambinho-MG, essa pesquisa buscou compreender se seus papéis socioespaciais e as relações de trabalho se alteraram a partir do momento que passaram a viver no espaço urbano. Partindo de entrevistas com mulheres do campo e migrantes da cidade, pode-se concluir que, no contexto da realidade de uma cidade pequena, permeada pela ruralidade, a busca por melhores condições de vida na cidade foi, de certa forma concretizada, embora ainda vivenciem papéis socioespaciais desiguais, especialmente, pelos postos ocupados com menor remuneração e pela responsabilidade integral do trabalho reprodutivo

Ethanol is one of the promising sources of hydrogen (synthesis gas), including in various energy applications. The production of synthesis gas from ethanol is possible in various ways, for example, such as steam and steam-air conversion, which are endothermic and thermoneutal reactions, respectively. Control and management of heat and mass transfer during the occurrence of these reactions is an important task, which can be solved through the use of catalysts on heat-conducting metal substrates. This paper presents the results of a study of the physicochemical properties of Pt, Rh, Pd, Ru, Ni, Co-containing structured catalysts deposited on a FeCrAl mesh support, studied in the processes of steam and steam-air conversion of ethanol. Among the tested samples, the ruthenium catalyst showed the greatest efficiency in the processes of steam and steam-air conversion of ethanol, providing an equilibrium composition of the products without visible signs of carbonization.
Existing and Promising Technologies for Hydrogen Sulfide Decomposition into Hydrogen and Sulfur
Authors: Zagoruiko A. N. , Kondrashev D. O. , Popov M. V. , Kleymenov A. V.
Published: January 2025

Hydrogen sulfide is a very attractive raw material for the production of hydrogen. The dissociation energy of H2S (21 kJ/mol at room temperature) is much lower than that of water (286 kJ/mol) or even hydrocarbons (76 kJ/mol for methane); moreover, the hydrogen bond energy in the H2S molecule is the lowest among all natural hydrogen compounds.

However, hydrogen sulfide has not yet found widespread industrial use as a raw material for hydrogen production. The main obstacle to the creation of an effective technology for this purpose is the very strict thermodynamic limitations of the reaction of hydrogen sulfide decomposition into elements H2S Û S + Н2 – Q.

This review is devoted to the analysis of the known approaches to the production of hydrogen and sulfur from hydrogen sulfide, their shortcomings that cause the failure of the previously proposed technologies, as well as the ways of possible creation of effective processes for this purpose. The review focuses on non-stationary cyclic processes, which can be considered one of the most promising ways to create an effective H2S decomposition technology.

The work investigated the process of oxidative oligomerization of Fischer-Tropsch synthesis products - a fraction of C10-C15 hydrocarbons with a total content of alkenes (mainly β- and γ-alkenes) of 64.7 wt. % using zirconium octoate as a catalyst. The hydrocarbon fraction was obtained on a zeolite-containing catalyst at a pressure of 2.0 MPa, a temperature of 250 °C, H2/CO ratio at the reactor inlet of 1.70, a gas space velocity of 1000 h-1 and circulation mode ratio range 0-16. It was found that at a temperature of 160 °C the catalyst content is 5.0 wt. %, process duration 6 hours and pressure (air) - 2.5 MPa, target fraction yield - 52.7 %. It was found that the oligomerization product has a low pour point of minus 31 °C. It was proposed to improve the viscosity characteristics of the oligomerization product by introducing additives into its composition, for example, polymethacrylates or polyisobutylene.

Published: January 2025

Zakrzepica zatok żylnych mózgowia (cerebral venous sinus thrombosis – CVST) to rzadkie, ale poważne schorzenie neurologiczne w populacji pediatrycznej. Występuje u dzieci w każdym wieku, ale noworodki i niemowlęta poniżej trzeciego miesiąca życia stanowią nawet do 43% przypadków. Etiologia tego schorzenia jest wieloczynnikowa, obejmuje wiele różnych predysponujących stanów i chorób. Wczesna i dokładna diagnoza oraz dobrze poprowadzona terapia są kluczowe dla uzyskania lepszych wyników leczenia. Proces diagnostyki może być utrudniony z powodu niespecyficznych objawów. W różnych grupach wiekowych objawy mogą się różnić, co może się przyczyniać do wydłużenia czasu pomiędzy pierwszym kontaktem z lekarzem a zainicjowaniem leczenia. Ponadto nie ma aktualnie żadnego markera, który mógłby zostać użyty w celu postawienia diagnozy. Z powodu tych trudności w diagnostyce zakrzepicy u dzieci w zależności od wieku pacjenta stosuje się odmienne techniki neuroobrazowania, takie jak ultrasonografia przezczaszkowa, rezonans magnetyczny lub wenografia rezonansu magnetycznego. CVST może powodować poważne neurologiczne i kognitywne powikłania. Na szczęście odpowiednio poprowadzone leczenie może obniżyć wskaźnik śmiertelności, a także zapobiec tym powikłaniom. W niniejszej pracy podsumowano aktualną wiedzę na temat CVST

Published: January 2025

Climate change significantly impacts health, food security, housing, safety, and work through long-term shifts in temperature and weather patterns. In Jakarta, these changes have led to the city experiencing the worst air pollution in Indonesia, with an Air Quality Index (AQI) score of 161. Nurses play a vital role in educating the public about behavioral changes to mitigate the effects of climate change. This study aimed to assess nurses' awareness, concerns, motivation, and behaviors related to health and climate change in a private hospital in Jakarta. This quantitative descriptive study involved 92 respondents selected through purposive sampling. The data were collected using the Climate, Health, and Nursing Tool (CHANT) questionnaire. The analysis revealed that nurses' awareness of evidence-based information on climate change ranged from "somewhat familiar" to "moderately familiar." Their concerns about the impacts of climate change were rated from "somewhat concerned" to "moderately concerned." Nurses' motivation levels were reported as ranging from "somewhat motivated" to "very motivated" regarding health and climate change. Behavioral practices to mitigate climate change varied, with activities at home ranging from "rarely" to "often" and those in the hospital ranging from "sometimes" to "often." This research highlights the need to enhance nurses' knowledge and awareness of health and climate change and serves as a reference for future studies exploring the intersection of nursing, health, and climate change in Indonesia.
Evolution of Russia’s relations with the oil-producing Persian Gulf monarchies in the context of securitization of the fourth energy transition
Authors: Kozhanov N.
Published: January 2025

The outbreak of the Russia–Ukraine conflict has reshaped the global energy landscape, extending the relevance of hydrocarbons for the global economy while highlighting the importance of renewables for national energy security. The article examines challenges and opportunities for cooperation between Russia and the Gulf Cooperation Council (GCC) countries amidst the accelerating Fourth Energy Transition. The ongoing global shift towards renewable energy presents significant risks for hydrocarbon-dependent economies, including declining oil demand, intensified competition in Asia, and market volatility. While GCC countries leverage the current high oil prices to advance their economic diversification agendas, the long-term acceleration of the energy transition, particularly in Asia and Europe, requires further adaptation. Russia’s active participation in OPEC+ and its willingness to coordinate production cuts emphasize the strategic nature of this partnership, ensuring the alignment of interests in mitigating the impact of global economic shifts. It is concluded that the synergy between Russia and GCC countries, grounded in shared vulnerabilities and strategic goals, will likely play a pivotal role in navigating the uncertainties of the global energy transition, creating a foundation for enduring economic and geopolitical collaboration. The critical role of OPEC+ as a platform for collaboration between Russia and GCC states that enables them to stabilize oil prices and align strategies to maintain economic resilience is also underscored.

Determinants of Muslim’s intention to boycott Israel-affiliated products: Evidence from Indonesia
Authors: Husaeni Uus Ahmad , Ayoob Mohammed Ashfaq
Published: January 2025

Purpose – The purpose of this study is to examine the factors that influence the intention to boycott products made or affiliated with Israel among Muslims in Indonesia. This study is grounded in the context of ongoing wars and conflicts in the Middle East, specifically in Palestine.Methodology – This research uses primary data collected from 412 respondents and the partial least squares structural equation model (PLS-SEM) method for data analysis.Findings – The main results show that animosity, intrinsic religious motivation, self-enhancement, product judgment, and attitude toward the boycott influence the intention to boycott. However, brand distrust does not determine the intention to boycott products affiliated with Israel.Implications – Indonesia is one of the largest markets for Muslims worldwide. Understanding the purchasing behavior of Muslim consumers in Indonesia can help marketers and multinational companies anticipate and strategically respond to potential boycotts, minimising financial losses. This is important because Muslim consumers in Indonesia often opt for alternative products when choosing to avoid those affiliated with Israel. Originality – Animosity was the most influential variable in this study. This reflects deep-seated resentment among Muslim consumers toward Israel, leading to a reluctance to purchase Israeli-affiliated products. They directly targeted Israeli-affiliated companies or products for boycotting as a form of expression of their anger and disapproval of Israel's invasion of Palestine. Interestingly, Muslim consumers in Indonesia still positively and favourably view products affiliated with Israel, even though they are reluctant to buy them.

Authors: Wibawa Dian Prihardini , Yanto Yanto , Zulkarnain Ariandi
Published: January 2025

Purpose – This study examines the mediating role of destination image and destination trust in the relationship between Electronic Word-of-Mouth (e-WOM) and the intention to visit halal tourism destinations, specifically focusing on Bangka Belitung. Methodology – This study employed a quantitative approach, collecting data from 292 respondents via an online survey. SEM was used to test the relationships among e-WOM, destination image, destination trust, and intention to visit. Validity and reliability tests, as well as goodness-of-fit measures, were applied to assess the model's robustness.Findings – The results indicate that e-WOM significantly influences both destination trust and destination image. However, neither destination image nor destination trust directly affect the intention to visit, and e-WOM itself does not have a direct significant impact on the intention. These findings suggest that, while e-WOM fosters positive perceptions and trust, other factors are more critical in driving the halal tourism intention.Implications – This study provides valuable insights for tourism stakeholders, particularly in halal tourism, by highlighting the importance of managing e-WOM to enhance trust and image. However, halal tourism providers must prioritize authenticity, cultural sensitivity, and visitor engagement to attract and retain tourists.Originality – This study contributes to the literature by exploring the mediating effects of destination image and trust in halal tourism, challenging the assumption that positive perceptions are always translated into behavioral intentions. It expands the understanding of how e-WOM impacts tourist decision making within a specific cultural and religious context.

Published: January 2025

Purpose – This study aims to analyze the behavior of investors' investment decisions, as reflected in the volatility of stock prices, especially at PT Bank Syariah Indonesia Tbk (BSI). The analysis here compares aspects of rationality and irrationality as well as their relationship with the stock prices of Bank Syariah Indonesia.Methodology – This study uses the Autoregressive Distributed Lag (ARDL) method to test aspects of rationality proxied by Price-to-Book Value (PBV) and Price-to-Earnings Ratio (PER), while aspects of irrationality proxied by mood sentiment (SWAV). Data were collected from February 2021 to February 2024 on a monthly basis, resulting in 37 research samples.Findings – The results show that PBV, PER, and mood sentiment have a significant effect on BSI stock prices. In the long term, PBV has a positive effect, while PER and mood sentiment have negative effects on BSI stock prices. In this situation, mood sentiment has the greatest influence on BSI stock prices, indicating that the volatility of BSI stocks is driven by irrationality.Implications – As the stock price is driven mostly by irrationality, investors must have fundamental and macroeconomic analysis skills as well as expertise when buying and selling stocks in order to minimize losses due to the irrational behavior. In addition, regulators and companies must provide transparent and accurate information to investors to reduce the irrational behavior.Originality – This study modifies the objective of Islamic banks’ stock prices in Indonesia by elaborating rational and irrational factors as the determinants of stock prices.

RAdam-Backpropagation-Based Model for Predicting Propped Fracture Conductivity
Authors: Liu Yuxuan , He Simin , Liu Zhonghui , Guo Jianchun , Peng Ziyi , Wu Liansong , Wu Yutong
Published: January 2025

Hydraulic fracturing is an effective method for enhancing both the initial reservoir production and ultimate recovery. Nevertheless, the conductivity of proppant fractures is a pivotal factor in the optimization of fracture designs within the context of fracture modification. Experimental testing methods for proppant fracture conductivity are costly and time-consuming, and the physical model is excessively complex and incomplete to account for all the influencing factors, resulting in low computational efficiency. A backpropagation neural network (BPNN) model was constructed using the RAdam optimization algorithm to identify a more efficacious method for predicting the conductivity of proppant fractures. The model was used to predict the fracture conductivity of two data types pertaining to the experimental data on the conductivity of geothermal and volcanic reservoirs. The prediction model is enhanced for three key areas. First, an isolated forest algorithm is used to assess and discard anomalous data points. Second, the objective function is optimized by employing the RAdam optimization algorithm, which has the advantages of both Adam and stochastic gradient descent (SGD). This guarantees rapid convergence and prevents the initial training phase from converging to a locally optimal solution. Moreover, this approach enhances the stability of the model training process. Finally, the rectified linear unit (ReLU) activation function may result in issues related to neuronal activity, including the potential for its disappearance. This study addresses this problem by employing the Kaiming initialization method. The experiments used a series of evaluation metrics, including the mean square error and coefficient of determination, to assess the predictive performance of the two data sets in the two distinct models. The experimental results indicate that the BPNN with RAdam optimization is a more effective approach for data pertaining to volcanic and geothermal reservoirs. Moreover, the prediction of the geothermal reservoir data is more precise than that of the volcanic reservoir data. This model can be used for rapid predictions based on existing fracture conductivity data, which can better guide the design of fracture modifications and is of great importance.

Authors: Li S. Q. , Tong Y. S. , Yan T. , Zhou Y. C. , Li W. , Sun X. F.
Published: January 2025

Efficiency and quality have always been the focus of coring operations. This paper proposes a new method of resonance coring to solve the problems of slow penetration rate, poor quality, and low efficiency when coring in deep formations. First, a stress field distribution model of rock under resonance coring conditions is developed in the paper, which specifies the magnitude of the force at any location inside the rock. Then, a 3D numerical simulation for resonance coring with the full-size drill bit is conducted based on indoor resonance coring experiments. Subsequently, a 2D numerical simulation on a single-tooth resonantly cutting rock is carried out by embedding a zero-thickness cohesive element globally. Finally, the resonance coring speedup mechanism is investigated from the perspectives of lithology, load form, and dynamic load characteristics, respectively. Based on the analysis undertaken, it can be concluded that the resonance coring method is feasible in principle. The harmonic dynamic load can aggravate the damage and the fracture degree of rock under the coring bit as well as the stress field on the surface of the core. The particle size of cuttings is larger and the proportion of tensile fracture of rock is increased by the combination of static and dynamic loads. The increase in frequency and amplitude of dynamic load is beneficial to promote the penetration rate of resonance coring. It is possible to improve coring efficiency without compromising core quality and wellbore integrity by optimizing the combination of static and dynamic loads. The study provides a new solution for efficient coring in deep and complex formations.
Revolutionizing High-Pressure Well Cementing: Enhancing Geopolymer Cement with Laponite for Sustainable and Sedimentation-Free Applications
Authors: Abdelaal Ahmed , Elkatatny Salaheldin
Published: January 2025

Sustainable geopolymer cement emerges as a prospective substitute to traditional Portland cement systems in the petroleum industry. Geopolymers offer different advantages over Portland cement, including reduced carbon emissions due to lower energy requirements during production, improved durability and chemical resistance, and the ability to use industrial byproducts as raw materials. This technology promotes sustainable waste management practices while maintaining high performance in various applications. This research aims to explore and maximize the geopolymer technology potential by addressing the issue of sedimentation in high-pressure well cementing applications. By incorporating Laponite particles into hematite-based Class F fly ash (FFA) geopolymer cement formulations, a solution is presented to mitigate sedimentation problems and ensure homogeneity and density uniformity along cement columns. Through the application of American Petroleum Institute (API) and non-API techniques, this study uncovers the remarkable benefits of Laponite in mitigating sedimentation problems and enhancing key characteristics such as strength and rheological properties. The findings reveal that Laponite-based geopolymer systems exhibit improved yield point (YP) and gel strength (GS), as well as reduced porosity and density variation. Adding 3% by weight of FFA of Laponite to the cement formulation reduced the density difference between cement sections from 39.38% when no Laponite was present in the system to only 0.58%. Additionally, the measured elastic properties indicate enhanced flexibility compared with Portland cement systems.

By determining the optimal Laponite concentration, this study achieves a step forward in promoting sedimentation-free and environmentally friendly non-Portland cementing methods in the petroleum industry.
Mapping and Analysis of Stream Sediment Heavy Mineral Fractions for Mineral Exploration: A Case Study of a Portion of North-Central Nigeria
Authors: Ngozi-Chika Chiazor Stephen , Mhlongo Sphiwe Emmanuel
Published: January 2025

Although artisanal mining is dominant in the Pan-African Mineral Belt in North-Central Nigeria, there are no known reports of studies detailing the mineralization, type of mineral occurrences, and processes controlling the mineralization in the area. This study aimed to conduct a geochemical evaluation of stream sediment heavy mineral fractions to understand the mineral ore characteristics. The adopted methodology involved delineating the study area based on potential mineralization and collecting stream sediment samples (n = 67) for heavy mineral fractions in a sampling density of 1 per 10 m2. The samples were analyzed for their geochemical and mineralogical compositions using instruments such as inductively coupled plasma-mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS), and energy dispersive X-ray fluorescence (EDXRF). The obtained results were subjected to Sequential Binary Partition, followed by appropriate mathematical log-ratio transformations to deal with inherent problems associated with compositional data. The obtained data was then analyzed using descriptive statistics, analysis of Median Absolute Deviation, and threshold mapping was employed to delineate geochemical anomalies. Univariate and multivariate analyses were employed to understand the geochemical associations, dispersion patterns, and geological processes. The result revealed that Mo, Cu, Zn, Au, Sr, Zr, Ce, W, Nb, Ta, and Be were anomalous in the stream sediment samples. The new anomalies of base and rare metals, precious metals, and gemstone likely mineralization were supported by evidence from mineralogical and mineral ore studies. The proving showed that mineralization of the Basement terrain is towards the West of Lokoja while the significant Fe anomalies suggest being from goethite, haematite, ± siderite-bearing ironstone formations generally found in the northern part of the study area.

Published: January 2025

Motor function defect caused by central or peripheral nerve injuries has become a global burden. Peripheral nerve transfer is an effective surgical method in restoring motor functions of upper limb after nerve injuries in general. However, the outcome of individual function recovery is less predictable. It is crucial to access the real-time monitoring of function improvement in the peripheral nerve level. Here, we developed a fully implantable multisite optogenetic stimulation system(FIMOSS), which is tailored for wireless, reprogrammable and long-term monitoring of peripheral nerve plexus functions. In Thy1-ChR2-EYFP mice, our system elicited diverse forelimb movements when illuminating each nerve bundle from different angles, confirming its spatial selectivity for the monitoring of precise brachial plexus functions. Furthermore, we applied FIMOSS on a nerve transfer mice model after traumatic brain injury and discovered innervation pattern of the transferred nerve to multiple forelimb muscles along with the functional compensation of adjacent nerve trunks in brachial plexus consecutively within 12 weeks after surgery, during which FIMOSS has demonstrated stable operation. Our technology enabled refined evaluation of electrophysiological and motor functions of peripheral nerve plexus, shining light upon personalized diagnosis and treatment after central or peripheral nervous system injuries or nerve surgeries.

Long-term PM2.5 exposure is a risk factor for cardiovascular mortality. Fossil fuel burning is a large source of PM2.5. Here, a global health impact assessment was conducted utilizing 7 future scenarios evaluating strategies to reduce PM2.5 exposure, including reducing fossil fuel use, air pollution control, adopting cleaner cooking methods and combinations thereof. Under current trends, air quality is projected to improve by 2050, but the absolute attributable burden of ischemic heart disease remains high in many regions. Promoting cleaner cooking is effective in the short term (by 2030) in South and Central America, Asia, and Africa in reducing the health burden. In the long term (by 2050), for most regions, only strategies that simultaneously target ambient and cooking related PM2.5 resulted in sustained improvements for reducing ischemic heart disease burden. For, North Africa and the Middle East region the population attributable fraction remains high across all scenarios. PM2.5 exposure remains above the WHO Air Quality Guidelines across all scenarios therefore additional strategies are required to improve air quality.

Published: January 2025

Background: Latin America faces multiple barriers to healthcare access, particularly affecting the pediatric population. Factors such as socioeconomic vulnerability, armed conflicts, disasters, and insufficient healthcare spending contribute to these difficulties. The barriers include financial, bureaucratic, and geographical issues, negatively impacting the well-being and development of children.
Objective: To identify the barriers to healthcare access in the vulnerable pediatric population of Latin America and recognize effective strategies to overcome them.
Methods: An scoping review was conducted in December 2024. A literature search was performed in databases such as BIREME, PubMed, and Scopus, including studies published between 2014 and 2024 in English and Spanish. Specific inclusion and exclusion criteria were applied, and the RAYYAN tool was used to manage the references.
Results: Twenty-eight articles met the selection criteria. Of these, 28.57% discussed sociodemographic barriers, highlighting geographical issues and gaps in government support; other articles addressed vaccination, mainly social stigmas and lack of supplies; and 17.8% focused on specific diseases, highlighting the lack of early access and complications. Additionally, 17.8% discussed strategies such as telemedicine to improve healthcare access in remote areas.
Conclusion: The barriers to healthcare access in the pediatric population of Latin America are diverse and complex. Telemedicine emerges as a promising strategy, ensuring access, follow-up, and medical consultation, reducing secondary complications due to late or non-existent care for remote communities. Additional studies with robust methodologies are required to improve the applicability of the recommendations.

A 36-year-old female was evaluated for pelvic pain of 6 months duration. She presented to our clinic with the MRI report suggestive of a well-defined, solid, T1 heterogeneously hypointense and T2 heterogeneously hyperintense lesion displaying post-contrast enhancement, central non-enhancing cystic areas, and areas displaying diffusion restriction, measuring 5.1 x 5.0 x 5.7 cm (APXTRXCC), noted in the mid pelvis at the level of the L5 vertebral body and the L5-S1 intervertebral disc. (Fig 1.). Black arrow pointing to the tumor. The lesion was noted closely abutting the bilateral iliac vessels posterolaterally. Anteriorly the lesion was noted abutting small bowel loops. Functional paraganglioma was ruled out by testing plasma-free metanephrines and 24-hour urine vanillylmandelic acid levels. CT scans of the head, neck, chest, and abdomen were performed to exclude the possibility of neural crest tumors in other sites. She underwent laparoscopic transperitoneal soft tissue tumor excision.When abdominal paragangliomas are possibly resectable, surgical excision is the preferred course of treatment; typically, this is done through an open procedure. The laparoscopic approach has been reported to be difficult for retroperitoneal paragangliomas due to the difficulty of handling a large tumor with forceps, extreme vascularization, and demanding localization despite the recent trend towards minimally invasive surgery.7
Demand for Digital and AI Skills in Healthcare: A NLP Analysis of Job Listings in China
Authors: 陈奕睿
Published: January 2025

Background: The rapid growth of the healthcare industry in China has led to a significant talent gap, particularly in the areas of digital skills and management expertise. This study aims to bridge this gap by analyzing healthcare job listings using natural language processing (NLP) techniques to identify specific skills and management capabilities in high demand.
Methods: We collected 42,032 healthcare job listings from eight major recruitment websites in China, focusing on positions requiring a bachelor’s degree or higher and posted within the last year. To extract relevant information from job descriptions, including required skills, qualifications, and roles, we employed an AI agent based on the latest ChatGPT model. The model was fine-tuned using advanced Prompt-Tuning techniques to adapt it to the specific context of healthcare job listings. This involved designing task-specific prompts, preprocessing the data to remove duplicates and normalize text, and training the model using the Hugging Face Transformers library.
Results: The analysis revealed a strong demand for technical skills such as data analysis (mentioned in 53.65% of listings), AI and machine learning (18.05%), and technology integration (28.3%). Compliance and data privacy skills were also highly demanded, reflecting the healthcare sector’s commitment to regulatory adherence and data security. Additionally, management and leadership skills were identified as critical, with project management mentioned in 46.32% of listings. Regional disparities were observed, with higher demand for digital skills in urban areas such as Beijing and Shanghai compared to rural regions. Emerging roles such as “digital health strategist” and “chief data officer” were also identified, highlighting the need for interdisciplinary collaboration and innovation.
Conclusions: This study provides valuable insights into the current and future talent demands in the healthcare industry. By leveraging NLP techniques to analyze job listings, we can identify specific skill gaps and develop targeted strategies for talent development and recruitment. This research contributes to the understanding of the healthcare talent gap and offers practical recommendations for policymakers, healthcare providers, and educational institutions to ensure a sustainable and skilled workforce in the healthcare sector. Future research should explore additional data sources and qualitative methods to gain a more comprehensive understanding of healthcare talent needs globally.
