Melt pool super solution reconstruction based on dual path deep learning for laser powder bed fusion monitoring
Authors: Lin Xin , Mao Yangkun , Wu Lei , Zhu Kunpeng
Published: December 2024

Melt pool monitoring in laser powder bed fusion (L-PBF) is an important foundation for process control and melting dynamics research. However, due to hardware limitations and the intense metallurgical phenomena during the melting process, the quality of the melt pool monitoring images cannot be guaranteed. This paper proposes a deep learning-based melt pool image super-resolution (SR) reconstruction method based on the particularity of melt pool images. It is an innovative dual-path structure. The first branch utilizes residual-in-residual structures and the efficient channel attention-Net attention mechanism to achieve the adaptive feature extraction of high-frequency information, thereby capturing effective melt pool boundary information. The second branch uses the U-Net structure to address the low utilization of overall characteristics of the melt pool in the chain-based SR network. In addition to the universal peak signal-to-noise ratio and structural similarity index measure metrics, the reconstruction accuracy of melt pool contour features is used to measure model performance, which intuitively reflects the significance of this work for melt pool monitoring. The results demonstrate that the proposed SR reconstruction method enhances the resolution and clarity of melt pool images. Furthermore, SR reconstruction of the melt pool effectively reduces errors in extracting melt pool features. This method provides a network paradigm for high-precision L-PBF monitoring. It integrates important boundary information and overall morphology features of the melt pool through a dual path structure, thereby achieving reliable SR reconstruction. This research will contribute to low-cost in situ monitoring of L-PBF and subsequent process control.

Published: December 2024

The Global Observation Research Initiative in Alpine Environments (GLORIA) is a world-wide network of sites dedicated to monitoring changes in alpine flora near mountain tops. In this project we analyzed data collected at 5 sets of GLORIA monitoring sites in the Rocky Mountains of the western USA. Each site was visited between 2 and 4 times in the years spanning 2003 to 2021. These sites include four National Parks (Great Sand Dunes National Park and Preserve, Rocky Mountain National Park, Yellowstone National Park, and Glacier National Park) and one wilderness area in the Pecos Wilderness within Santa Fe National Forest. We focused on testing the climatic sensitivity of the alpine flora as a whole, and the relative responsiveness of plant species based upon their commonness or rarity, their geographic ranges, and other aspects of their life forms and of site characteristics.

We find that across all sites and species there is strong evidence for turnover of the flora in the GLORIA sampling areas, with rare species disproportionately increasing over time and common species generally declining. We also find that graminoids and shrubs have increased more than forbs, as has been found or suggested in other studies. Multiple climate variables have significant influence on changes in plant cover. In particular, higher annual precipitation increases abundance, on average. Lower growing season precipitation, higher growing degree days (reflecting both warmer temperatures and more days of higher temperatures), and higher mean temperatures also lead to increasing abundance. Also, species with lower latitudinal ranges tended to increase more over time, while species with more northerly ranges often declined. Within these general trends there are substantial differences between species, as indicated by random species-level effects, but there were no strong patterns in these effects that would suggest additional generalizations between species groups.

Beyond our findings regarding the drivers of alpine plant dynamics, we examined factors that could potentially add bias or uncertainty to the data sets and made recommendations regarding data collection going forward. Among these suggestions are: 1) that all the NPS GLORIA teams consider consulting with previous species lists when performing field surveys; 2) that redundant temperature data loggers be deployed by at least two team members at each plot; and 3) that a careful training protocol be developed to better standardize cover estimation across parks and censuses. We expand on these recommendations at the end of report.

A pharmacy is a place or business that is specifically dedicated to providing medicines and other health products to the public. This place is also known as a drugstore or drug store in some countries.  Pharmacies provide medicines both prescribed by doctors and over-the-counter (over-the-counter), to help patients cope with health problems they are experiencing.Some pharmacies also offer additional services such as blood pressure checks, vaccinations, simple health checks, and health counseling to the public.  In applying a priori methods to pharmacy, a deep understanding of data structure and proper product classification is needed to overcome this problem. By knowing the pattern of frequent purchases, pharmacies can place items that are often purchased together close together on shelves or strategic locations. This can increase the convenience of buyers and speed up the purchase process. A priori methods are techniques in data mining that are used to find hidden patterns or associations in large datasets.  A priori methods look for relationships between items in a dataset that often appear together.  The main principle of the a priori method is that if an item-set appears frequently together, then it is likely that the item-set will also appear frequently together in other transactions.

Authors: Faradilah Rahma , Harahap Syaiful Zuhri , Irmayanti Irmayanti
Published: December 2024

Clustering of book borrowing patterns in the University of Labuhanbatu library aims to identify and understand student preferences and habits in borrowing books. With this analysis, the library can be more effective in managing book collections, ensuring the availability of frequently borrowed books, and improving the quality of service according to student needs. Using clustering techniques also helps in designing a more targeted book procurement strategy, so that existing resources can be optimally utilized to support the teaching and learning process. In this study, the methods used are Kf-Growth and Apriori to identify book borrowing patterns. Kf-Growth is used to find frequent itemsets or collections of books that are often borrowed together, while Apriori is used to generate association rules that reveal the relationships between borrowed books. Both of these methods allow for a more in-depth and comprehensive analysis of book borrowing patterns in the library, with the ability to handle large amounts of data and identify significant relationships between items. This process involves several stages, including data preprocessing, algorithm application, and evaluation of the results to ensure the validity and accuracy of the resulting clustering. The results of the clustering analysis show a very good confidence value, with many male and female students borrowing the book "Pengantar Akuntansi" consistently. This borrowing pattern shows that books related to economics and accounting have a high level of demand. The Kf-Growth and Apriori methods have proven to be very effective in clustering, providing accurate and reliable results. With these results, the Labuhanbatu University library can take more informative and strategic steps in managing book collections, ensuring that frequently borrowed books are always available, and improving the borrowing experience for students.
RESPONSIBILITY OF LAND DEED MAKING OFFICER FOR SALE AND PURCHASE DEED BASED ON POWER OF ATTORNEY TO SELL LAND THAT VIOLATES RULES (Sengketi District Court Decision Number 15/Pdt.G/2021/PN Snt)
Authors: Primanto Muhammad Abimukti
Published: December 2024

The Land Deed Making Office (PPAT) is a public official responsible for creating authentic land deeds. In carrying out their duties, they also assist in land registration activities and the transfer of land rights. One way to transfer land rights is by creating a power of attorney to sell land based on Article 1792 of the Civil Code. The research method used is a doctrinal research type, which is descriptive and analyzed qualitatively. In the case of the district court ruling Sengeti Number 15/Pdt.G/2021/PN Snt, there was bad faith on the part of the buyer in fulfilling the power of attorney to sell in that case. This issue prompts the author to delve deeper into and reveal the accountability of the PPAT who created the power of attorney to sell, considering the bad faith motive of the buyer and the sanctions that can be imposed based on the legal events in this case.Keywords: Civil Code; The Land Deed Making Office; Power of Attorney to Sell

U radu autor sistematizirano i kronološki prikazuje i analizira medijske izvještaje o operativnom djelovanju stranih obavještajnih službi u Republici Hrvatskoj u periodu 2002.-2022. s posebnim fokusom na maligne aktivnosti Bezbednosno-informativne agencije (BIA). Na temelju novinskih članaka dostupnih u digitaliziranim arhivskim bazama vodećih hrvatskih i srbijanskih mainstream medijskih kuća (Nacional, Vjesnik, Telegram, Index.hr, Dnevno.hr, Tportal, Slobodna Dalmacija, Novosti, Jutarnji list, Net.hr, Express, Globus, Večernji list, Politika.rs, Telegraf.rs, Ekspres.net, Republika.rs, Blic.rs, Kurir.rs itd.) autor izrađuje kvantitativno/kvalitativnu kronološku Excel bazu koja sadrži informativne podatke o člancima za dati period, njihovoj postotnoj i brojčanoj zastupljenosti po medijskim kućama koje su kategorički svrstane po pojedinim zemljama porijekla (Hrvatska i Srbija) te sadržajima izvještaja. Detektiranje i razumijevanje dominantnih i aktualnih tema koje su bile predmetom izvještavanja u medijima kroz dati period, predstavlja osnovno težište znanstvene teorije rada i metodološkog pristupa. Kronološkim proučavanjem podataka, identificira se učestalost i vrsta izvještaja koji su obrađivali aktivnosti spomenute obavještajne službe. Također, važan element istraživanja čini i analiza povijesnog, sigurnosnog i nacionalno-regionalnog društveno-političkog konteksta koji predstavlja elementaran okvir za shvaćanje određenih pojava pri čemu se autor konzultira relevantnom domaćom i stranom znanstvenom i stručnom literaturom te provjerenim internetskim izvorima i podacima. Rezultati istraživanja trebali bi praktično i teorijski pružiti uvid u medijsku percepciju i zastupljenost aktivnosti stranih obavještajnih službi, poglavito BIA-e u medijima tijekom navedenog razdoblja. Prema tome, osim kvantitativno-statističkih pokazatelja, istraživanje se fokusira na razumijevanje prijenosa informacija, dezinformacija i misinformacija prema javnosti. Kombinacijom kvantitativnih i kvalitativnih podataka, pokušava se stvoriti cjelovita slika o tome kako su se aktivnosti stranih obavještajnih struktura u Republici Hrvatskoj, posebice BIA-e, reflektirale u medijskim izvještajima tijekom posljednja dva desetljeća. Ova analiza pruža temelj za daljnje istraživanje o percepciji mainstream medija i javnosti o stranom obavještajnom djelovanju i njegovom stvarnom empirijskom, tj. teorijskom utjecaju na političke i sigurnosne procese u Republici Hrvatskoj.

Authors:   Misan Radiation Oncology Center, Misan Health Directorate, Ministry of Health/Environment, Misan, Iraq, Alshewered Ahmed Salih
Published: December 2024

Background. During the reproductive phase, the endometrium undergoes cyclical structural changes. Endometrial hyperplasia (EH) is a prevalent condition that arises from a combination of estrogen exposure and insufficient progesterone levels. Endometrial cancer (EC) is the second most common gynecologic malignancy, with the likelihood of EH progressing to EC ranging from 1% to 29%. The objective of this study is to conduct a comprehensive assessment of various forms of endometrial hyperplasia, benign endometrial tumors, and endometrial cancer (EC). Methods. A review of published papers from major databases, including PubMed, Scopus, and Google Scholar, was conducted. The search included original research articles and reviews on EH, benign endometrial tumors, and EC. Case reports, series, and clinical images were excluded. Results. Information on the selected topics was summarized, including epidemiology, etiology, histopathological classification, anatomy, biological and molecular characteristics, detection and prevention, clinical manifestations, staging, diagnostic workup, prognostic factors, and management. Conclusion. Endometrial hyperplasia and endometrial cancer are two of the most common problems in women. EH is a major precancerous condition for EC, and EC is associated with a poor prognosis if diagnosed late. The epidemiology and outcomes of both conditions vary according to several factors, including ethnicity, environment, socioeconomic status, heredity, drugs, hormones, and the aging process.

Objectives. We present an exceptionally rare case of acquired hemophilia B coexisting with lupus anticoagulant (LA), with the concurrent presentation of bleeding and thrombosis. This unique and challenging case poses significant diagnostic and management difficulties for clinicians. Case presentation. A 45-year-old male presented with severe cephalgia, gastrointestinal bleeding, and a subacute subdural hematoma. Laboratory investigations revealed prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), positive LA, and a significant reduction in factor IX levels. Despite receiving fresh frozen plasma (FFP) and packed red cells (PRC), the patient’s coagulation abnormalities persisted. Outcome. Further investigation led to the diagnosis of acquired hemophilia B with positive lupus anticoagulant. We suspected that a factor inhibitor or vitamin K deficiency might be contributing to the bleeding disorder, necessitating additional confirmatory diagnostics. The patient ultimately chose to be discharged against medical advice, highlighting the ongoing challenges in diagnosing and managing such complex conditions. Conclusions. Bleeding disorders in the presence of autoantibodies require comprehensive diagnostic testing, including specific factor inhibitor assays, to guide appropriate treatment. The coexistence of both bleeding and thrombosis in this patient illustrates the paradoxical effects of LA on coagulation, providing valuable insights for clinicians encountering similar cases.

Published: December 2024

Hybrid nanofluids have emerged as a promising medium for enhancing heat transfer in various cooling systems, particularly in jet impingement cooling applications. This study conducts a numerical analysis of the heat transfer performance of aluminium oxide (Al₂O₃) and copper (Cu) hybrid nanofluids at different mixing ratios (25:75, 50:50, and 75:25) under jet impingement cooling conditions. The research employs computational fluid dynamics (CFD) simulations to investigate the thermophysical properties and heat transfer behaviour of these hybrid nanofluids at a constant nanoparticle concentration of 0.5% by volume. Among the tested compositions, the 50:50 Al₂O₃ mixture demonstrated the highest heat transfer coefficient and surface temperature reduction, improving heat transfer by up to 22.20% compared to pure water. The findings suggest that the balanced thermal properties of this ratio has optimized cooling performance, making it suitable for industrial cooling applications, such as electronics and power systems, where efficient heat dissipation is critical.

Published: December 2024

The purpose of this qualitative research is to identify the financial behavior patterns of Gen Z related to the FoMO phenomenon. This research uses a netnographic research method. The research period is September 21 to November 20, 2024. The research data consists of comments analyzed from content related to clothing, food, beauty, and finances of Gen Z on Instagram and TikTok applications. The results of the study indicate that Gen Z tends to be hedonistic and impulsive, especially focusing on price and free shipping when shopping online. Although Gen Z strives to invest and save money, their financial balance is easily influenced by social media advertisements, influencer reviews, and free shipping, which encourages Gen Z to become FoMO. This is evidenced by the presence of content related to clothing, food, and beauty, indicating that high interest in the content is influenced by reviews from influencers. Gen Z tends to use Pay Later to get online shopping promotions. With the research results above, financial education content really helps Gen Z to be more aware in managing their finances so that they can control FoMO behavior that leads to hedonism and impulsive attitudes that ultimately lead to doom spending. With the function of educational content, it is hoped that Gen Z can make better use of their finances, so as to avoid hedonism and consumerism.

The present paper discuss the results of an experimental study about self-compacting concretes (SCC) prepared with different mineral admixture (cal,Pz and Br). It was evaluated the effects of the use of the mineral additives on the properties of SCC. Four types of SCC mixes were produced. The amount of cement, fine and coarse aggregate of water and superplasticizer was kept constant for all mixtures. The blended cement (Portland cement + admixture) remained constant at 490 kg/m3 and included 20% by weight of recycled mineral additives. The different between the mixtures done in the 20% of fillers . TheThe rheology of fresh SCC was determined according to the requirements of the 206-9 standard, using the spread (sprawl), L-box, and stability (sieve) tests. The properties of the hardened SCC were evaluated through compression strength tests at 3, 7, 28, and 90 days, physico-thermal properties (λ, Cp, α) at 90 days, and absorption by total immersion at 90 days. The results showed that among the mineral additives used, the incorporation of waste bricks significantly reduced the rheology of SCC. However, ternary mixtures of limestone and waste bricks improved the rheological properties of SCC. Mechanical properties, such as compressive strength and physico-thermal properties, were also influenced by the addition of fillers, although the effects varied depending on the type of additive used. Nevertheless, the ternary mixtures of limestone and waste bricks yielded the best results in terms of strength, porosity, and durability.

Published: December 2024

As energy resource prices are on the rise and the stability of energy supplies is increasingly challenged by the current geopolitical climate, it is essential to scrutinize the capability of households to adapt to the resulting circumstances by assessing the current and potential household energy supply and adapting solutions to energy consumption habits. The aim of the research is to study of the energy consumption behaviour of households in the Baltic States amidst a significant increase in prices. The research methods encompass the examination of literary sources, categorization, amalgamation, abstraction, and juxtaposition in the theoretical segment, as well as a case study focusing on energy consumers in Lithuania, Latvia, and Estonia. Notably, the study presents a unique analysis of the unprecedented scenario of substantial price hikes across all energy usage categories in the region. An examination of individual responses concerning energy consumption illustrates a notable escalation in household expenditures on electricity and heating. Households are endeavouring to curtail energy expenses through various conservation techniques. A correlation between income levels and household energy consumption is evident.
Exploring the approaches towards support of academic entrepreneurship: evidence from an emerging market

Published: December 2024

Over the past three decades, an exponentially growing body on elements and actors of the concept of an entrepreneurial university has emerged. Compared to its western European counterparts, however, the idea of the third role of the university has only recently been implemented in Central and Eastern European countries, and thus both research and entrepreneurial practice grapple with empirical results. In this paper, we attempt to fill this gap while adopting a case study approach to examine the issue of what resources a prominent technical university operating in the emerging market of the Czech Republic transfers to academic ventures to utilise and commercialise university research results. Within a survey, nine academic founders and two university representatives were interviewed to assess the role of university resources in facilitating academic entrepreneurship. Our research results suggest that creating infrastructure to foster the third role of universities in an emerging market is a complex and long-term issue. Formal institutions embedded in the intra-university organisational structure, such as knowledge transfer offices and entrepreneurial centres, need to be equipped with sufficient resources and competences. Skilled people with their own network of contacts to intra-university departments and external environment represented by regional incubators, venture capital providers, business angel associations, and experienced entrepreneurs should be involved in the process of creating and increasing capacity. Furthermore, the upcoming agenda should undoubtedly acknowledge the significant role of entrepreneurship education with a focus on talent recognition and entrepreneurship training to impact the entrepreneurial intentions of researchers and students. Overall, we also conclude that the motivation of academics to commercialise their inventions could be positively affected by the applied concepts of assessing their performance. Finally, this study shows that measures at all management levels have to be adopted to create a vital organisational culture that will be in alignment with the vision of entrepreneurial university. The novelty of this paper is twofold. First, the study provides a useful methodological concept of data collection as the multi-level approach was applied for studying the phenomenon of entrepreneurial university. Furthermore, the research findings have valuable implications for university authorities, as well as national and local policy makers, in creating growth programmes and supporting the entrepreneurial mindset.
The impact of social features on the financial sustainability of pension systems in Central and Eastern Europe and Baltic States
Authors: Dumiter Florin Cornel , Schebesch Klaus Bruno , Nicoară Ștefania Amalia , Bențe Cristian
Published: December 2024

This paper analyses the financial sustainability of pension systems from the perspectives of labour supply, population aging, and demographic changes. The time period chosen was 1995 to 2022 and it takes into account nine countries from Central and Eastern Europe and the Baltic States. The econometric modelling techniques used are traditional linear regression, ridge and lasso regression, cross-validated glmnet models, and xboost flexible model used for the whole nine countries and also for country groups. The empirical results show that government expenditures and revenues in terms of social security funds are influenced by the demographic changes of the population that we face nowadays, are bound to the population aging phenomenon, and are dependent upon the elderly labour supply movements. The conclusions of this article reveal the practical need to reshape the financial sustainability of pension systems in all nine countries by developing a sustainable pension scheme that needs to be adjusted to the new social, demographic, and behavioural patterns of labour supply.

The Galactic bulge hosts the Milky Way’s oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge’s primordial building blocks, making these stars witnesses to the Galaxy’s early chemical enrichment. The Galactic bar currently dominates the bulge’s region, altering the orbits of objects formed before its formation and complicating the trace of the field stars’ original clusters. Here, we present the discovery of a fossil record of this evolution, SOS1—a star trapped in the bar, exhibiting significant enhancements in nitrogen, sodium, and aluminum, typical of second-generation GC stars. SOS1 also shows an s-process Ce enhancement, suggesting an old age and early enrichment by fast-rotating massive stars in the Galaxy’s earliest phases. With the purpose of finding the SOS1's parent GC, we derive its precise chemodynamical properties by combining high-precision proper motions from Gaia with Apache Point Observatory Galactic Evolution Experiment–detailed chemical abundances. Our analysis suggests that SOS1 was possibly stripped from the GC Terzan 5 by the Galactic bar’s gravitational influence approximately 350 Myr ago. We also found chemical similarities suggesting that SOS1 belonged to the most metal-poor, ancient, and peripheral stellar population of Terzan 5. These results not only support the hypothesis that Terzan 5 is a remnant of a primordial building block of the Galactic bulge but also suggest this cluster continues losing stars to the bar. Our method highlights how powerful the use of chemodynamical properties in the Gaia era is for tracing the Galaxy’s evolutionary history.

The ~5 Myr PDS 70 is the only known system with protoplanets residing in the cavity of the circumstellar disk from which they formed, ideal for studying exoplanet formation and evolution within its natal environment. Here, we report the first spin constraint and C/O measurement of PDS 70b from Keck/KPIC high-resolution spectroscopy. We detected CO (3.8σ) and H2O (3.5σ) molecules in the PDS 70b atmosphere via cross correlation, with a combined CO and H2O template detection significance of 4.2σ. Our forward-model fits, using BT-Settl model grids, provide an upper limit for the spin rate of PDS 70b (<29 km s−1). The atmospheric retrievals constrain the PDS 70b C/O ratio to

dex, consistent with that of its host star. The following scenarios can explain our measured C/O of PDS 70b in contrast with that of the gas-rich outer disk (for which C/O ≳ 1). First, the bulk composition of PDS 70b might be dominated by dust+ice aggregates rather than disk gas. Another possible explanation is that the disk became carbon enriched after PDS 70b was formed, as predicted in models of disk chemical evolution and as observed in both very low-mass stars and older disk systems with JWST/MIRI. Because PDS 70b continues to accrete and its chemical evolution is not yet complete, more sophisticated modeling of the planet and the disk, and higher-quality observations of PDS 70b (and possibly PDS 70c), are necessary to validate these scenarios.
Grande précarité en France : analyse de la persistance du cloisonnement des secteurs social, médical… et psychologique

Dans cet argumentaire, nous nous interrogeons sur les raisons pour lesquelles les psychologues sont peu présents sur le terrain de la grande précarité en France, alors que les besoins en santé mentale y sont relativement bien décrits. Pour répondre à cette question, nous discutons la manière dont les sciences sociales ont permis des avancées dans l’accompagnement des personnes Sans Domicile, alors qu’historiquement, les sciences psychologiques se sont peu penchées sur cette population. Nous évoquons également le cloisonnement des secteurs médical et social, qui rend les soins en santé mentale plus difficiles d’accès et limite les interventions psychologiques. Nous concluons cet article en soulignant certaines avancées récentes sur cette question et encourageons les dispositifs à tendre vers une compréhension médico-psycho-sociale de la grande précarité.

Introduction : La prise de décision éclairée par les données probantes est une stratégie efficace pour répondre aux besoins de santé des populations. Cependant au Burkina Faso, le concept d’utilisation des données probantes pour la prise de décision rencontre des difficultés. La présente étude avait pour objectif d’identifier les obstacles à l’utilisation des données probantes pour la prise de décision au ministère de la Santé et de l’Hygiène Publique du Burkina Faso. Méthodes : Il s’est agi d’une étude qualitative qui a consisté à la réalisation d’entretiens individuels semi-structurés avec des informateurs clés. Une analyse thématique a été réalisée à l’aide du logiciel de traitement de données qualitatives NVivo 12. Résultats : Les principaux obstacles à l’utilisation des données probantes pour la prise de décision étaient : l’insuffisance de financement pour la production et la valorisation des résultats de recherche, la qualité insuffisante des données, les difficultés d’accès aux résultats, l’insuffisance d’interaction entre les acteurs, l’inadéquation entre les besoins du ministère et les recherches menées, les conflits d’intérêts, l’influence des partenaires et le format inadéquat de présentation des résultats de recherche. Conclusion : Cette étude a permis de mettre en évidence les défis liés à l’utilisation des données probantes pour la prise de décision en santé publique au sein du ministère de la Santé et de l’Hygiène Publique du Burkina Faso. Traiter ces obstacles pourrait contribuer à améliorer la prise de décision éclairée par les données probantes pour soutenir les interventions de santé publique favorables à la santé des populations.
Effet de l’inclusion financière sur le recours des ménages aux soins de santé au Togo
Authors: Sy Ibrahima , Atchi Kokou Fambari
Published: December 2024

Introduction : L’accès aux soins de santé au Togo est fortement influencé par l’inclusion financière, un concept qui englobe l’accès des ménages aux services financiers formels. Dans un pays en développement comme le Togo, cette relation est cruciale pour comprendre les défis liés à la santé. Les ménages qui ont un accès limité aux services financiers peuvent rencontrer des obstacles significatifs pour obtenir des soins médicaux, ce qui peut exacerber les inégalités en matière de santé. But de l’étude : L’objectif général de cette étude est d’analyser l’effet de l’inclusion financière sur le recours des ménages aux soins de santé au Togo. Résultats : L’inclusion financière a un effet positif sur le recours des ménages aux soins de santé. Les hommes ayant accès à des services financiers formels demandent plus de soins de santé que les femmes dans des situations similaires. Les ménages urbains inclus financièrement accèdent davantage aux soins de santé par rapport aux ménages ruraux inclus. Conclusions : L’étude renforce l’idée que des politiques d’inclusion financière efficaces peuvent avoir des répercussions positives sur la santé publique, en particulier dans les contextes vulnérables comme celui du Togo. Les efforts pour améliorer l’accès aux services financiers devraient être intégrés dans les stratégies de santé publique afin de maximiser leur impact.
