Published: January 2025

This paper aims to demonstrate the application of a new automatic geosteering method that combines probabilistic interpretation with artificial intelligence (AI) for look-ahead decision-making. We expand on our previous synthetic workflow by testing our geosteering robot, named “PluRaListic,” into a synthetic environment modeled after a commercial cloud-based geosteering environment from the ROGII Geosteering World Cup (GWC). This synthetic setup allows for comprehensive testing and validation of the robot’s capabilities in a controlled yet realistic setting, ensuring that the methodologies developed can be robustly assessed before potential deployment in real-world operations. Our automatic geosteering method combines a reinforcement learning (RL) algorithm with the particle filter (PF) method. PF continuously assimilates real-time log measurements obtained during geosteering operations, producing hundreds of most-likely geology interpretations. Simultaneously, RL uses the information gathered from PF outputs to optimize steering decisions. The robot implementation automatically collects the new well trajectory and logs and passes the latest data through the PF. The RL uses the most-likely interpretations to balance the short- and long-term steering priorities and outputs a single recommendation that the robot sends back to the synthetic environment. The operation of our robot significantly surpasses real-time operation requirements, making one steering decision in approximately 4 seconds, far below the 2-minute-per-stand drilling time allocated for the GWC. After running 1,000 simulations, the median outcome achieved 77.3% reservoir contact, placing the robot in the top 14% of human experts. Moreover, the robot’s best attempt surpassed all experts, highlighting its potential to exceed human expertise in optimal scenarios. This work represents a radical innovation in geosteering that contributes to the advancement of automated geosteering frameworks. Future developments will focus on improving the performance and reliability of our robot. We also aim to enable an interactive framework for seamless collaboration between human experts and the robot, combining human expertise and consistent AI decision-making to achieve more precise and efficient drilling operations.

Published: January 2025

Preformed particle gels (PPGs) have been broadly used in temporary plugging steering fracturing techniques. However, it is difficult to achieve both excellent mechanical and degradable properties in conventional PPGs. To address this issue, double crosslinked self-degradable preformed particulate gels (DCSPPGs) were prepared using starch, hydroxyethyl acrylate, and acrylamide, crosslinked with poly (ethylene glycol) diacrylate (PEGDA) and borax. The structure was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM), confirming the successful preparation of DCSPPGs. The mechanical properties of DCSPPGs indicate that the elastic modulus of DCSPPGs reached 22 918 Pa, which is much higher than that of most similar particle gels. Meanwhile, DCSPPGs can be degraded to a low-viscosity liquid within 36 hours without any visible solid residues. It shows that DCSPPGs have excellent mechanical and degradation properties. In addition, this study systematically evaluated the effects of particle size, temperature, and monovalent (Na+) vs. divalent (Mg2+ and Ca2+) ions on the swelling and degradation properties of the DCSPPGs. These findings reveal that DCSPPGs maintain exceptional degradation performance in high-temperature (150°C) and high-salinity (30% NaCl) environments. Core displacement experiments showed that the maximum breakthrough pressure of the core after DCSPPGs sealing could reach 27.69 MPa and that the permeability injury rate of the core after degradation was only 3.55%. It shows that DCSPPGs have excellent sealing performance and minimal formation damage post-degradation.
The low-flow mask oxygen is a more effective, comfortable, and easy-to-follow treatment for psychogenic hyperventilation syndrome: a double-blind, randomized controlled trial
Authors: Yang Linhe , Yuan Dongmei , Luo Zhenyu , Li Yunying , Zhu Xiuli
Published: January 2025

Objectives
To compare the effect of low-flow mask oxygenation (LFMO) with breathing training (BT) for psychogenic hyperventilation syndrome (PHVS), providing more options and evidence for clinical treatment.
Methods
A randomized double-blinded controlled experiment was registered in the Chinese Clinical Trial Registry on 01/06/2023 with a defined number (ChiCTR2300072044) and approved by the Ethics Committee of (REDACT) (GYZXLL2023070) and then conducted there from 10 May 2024 to 23 November 2024. Participants with PHVS were blindly randomized into the LFMO group and the BT group, then the LFMO group inhaled 3L/minute oxygen with the oxygen mask and breathed freely, while the BT group performed the breath training led by researchers face-on-face. The recovery length from PHVS, the Nijmegen Questionnaire score at fifteen minutes since the intervention, the Nijmegen Questionnaire score at the end of the intervention, and the comfort/tolerance score (participant rating via NRS) were collected as the primary outcome. The secondary outcome was measured by the mean breath rate during the recovery (Calculated by dividing the total number of breaths during the intervention by time) and laboratory results, including the PH, lactate, K+, Ca2+, PO2, and PCo2.
Results
Forty-five participants (all Asian) completed the study and were included in the analysis (21 for the LFMO group and 24 for the BT group), mainly female (75%, n=33). All demographic characteristics between the two groups are within the reasonable range and have no significant difference. However, significant differences were measured among the outcomes, including the oxygen index (480.22±29.64, 311.01±15.45, p<0.001), Mean breath rate during recovery (19.17±1.74,28.24±2.53, p<0.001), and the LFMO group showed significant advantages in both the length of recovery (22.94±2.81, p<0.001) and comfort/tolerance (5.86±1.24, p<0.001).
Conclusion
Compared to breath training therapy, the low-flow mask oxygenation is a more effective, comfortable, and easy-to-follow treatment for PHVS.

Published: January 2025

Objectives: This study aimed to: (1) Rigorously validate the Chinese PrAS-S psychometrically; (2) Precisely determine pregnancy-related anxiety prevalence and severity among pregnant women; (3) Scrutinize its significant influencing factors.
Background: Given pregnancy-related anxiety’s importance for maternal mental health, we used PrAS-S for a cross-sectional study of 300 Urumqi pregnant women. We aimed to evaluate anxiety levels, analyze status and factors, and support clinical psychological nursing.
Methods: Employing convenience sampling, 300 pregnant women from three Urumqi tertiary hospitals were surveyed with general and Chinese PrAS-S questionnaires. Univariate and multiple linear regression analyses explored determinants and assessed the scale’s reliability and validity.
Results: The Chinese PrAS-S proved reliable and valid. CR values for differentiation were 9.670 - 18.920, I-CVI 0.83 - 1, Cronbach's α 0.778 - 0.906, and test-retest correlation coefficients 0.857 - 1. The prevalence of pregnancy-related anxiety was 61.67% (185/300). Age, marital status, gestational age, marital satisfaction, baby's gender expectation, and concurrent pregnancy complications had a profound impact.
Conclusions: The Chinese PrAS-S is a convenient, reliable tool for quickly assessing pregnancy-related anxiety. With a high incidence rate, preventive and intervention strategies, considering influencing factors, must be strengthened to protect pregnant women's mental health.

Published: January 2025

Intensive immunosuppressive therapy (IST) can greatly improve the survival prognosis of severe aplastic anemia (SAA). Nevertheless, approximately 30% of SAA patients did not respond to initial IST treatment. For these patients, salvage treatment poses a challenge. Therefore, predicting the efficacy of IST for SAA at initial diagnosis and developing the optimal curative regimen may enhance treatment outcomes. Trisomy 8 is one of the most common cytogenetic abnormalities in myeloid neoplasms and the BCL6 corepressor (BCOR), a transcription factor, also plays a role in hematopoiesis by inhibiting differentiation toward the myeloid lineage. It is rare that trisomy 8 and BCOR mutation present simultaneously in SAA, which may predict the efficacy of IST for SAA independently. Herein, we presented a SAA patient with both trisomy 8 and BCOR mutation at diagnosis. The bone marrow (BM) aspirate showed hypocellular BM and the bone marrow biopsy revealed a severe hypocellular bone marrow (15% cellularity). The patient rapidly relieved with reduced transfusion and achieved response after IST treatment. Biopsy about 3 months following IST showed remission, and the volume of hematopoietic tissue reached 40%. BM aspirate showed improvement (Grade III). Cytogenetic analysis revealed a normal karyotype. NGS still revealed BCOR mutation, and complete blood cell count results were improved. In conclusion, we are the first to describe a rare case of SAA with both chromosome 8 abnormality and BCOR mutation in detail. Review of the literature showed that the coexistence of trisomy 8 and BCOR mutation may represent a new distinct entity in SAA.
A Kolmogorov–Arnold Compute-in-Memory (KA-CIM) Hardware Accelerator with High Energy Efficiency and Flexibility
Authors: Sudarshan Chirag , Manea Paul , Strachan John Paul
Published: January 2025

Kolmogorov-Arnold Networks (KAN) are an emerging AI model designed for AI+Science applications, offering up to 100x fewer parameters than conventional Multilayer Perceptrons (MLPs). KAN relies on computationally expensive non-linear functions, unlike MLPs, which are dominated by matrix multiplication. This limits KAN's compatibility with energy-efficient hardware accelerators like Compute-in-Memory (CIM), restricting it to energy-inefficient general-purpose chips. To address this gap, we propose KA-CIM, a memory-centric design for energy-efficient computation of KAN inference. We leverage the Piece-Wise Linear (PWL) approximation of non-linear functions to convert complex computations into Multiply-Accumulate (MAC) operations and pre-storing segment parameters, an approach suitable for memory-centric design. A specialized CIM unit dynamically routes inputs to appropriate PWL segments, while a crossbar array retrieves segment slope and intercept to execute the MAC operations. The tile partitioning feature facilitates higher PWL segments for improved accuracy without significant energy penalties. This architectural design facilitates efficient and flexible computation of arbitrary non-linear functions of KANs. Beyond KAN inference, KA-CIM's capability extends to multi-variable equations and derivative computations. KA-CIM achieves energy-delay products 1073x lower than CPU for non-linear operations. When executing KAN, it achieves 77x lower energy-delay product than a 100 TOPS/W CIM accelerator executing MLP for the same task.
Accuracy of rubber-related deforestation maps
Authors: Hoang Nguyen Tien , Potapov Peter , Olofsson Pontus , Kanemoto Keiichiro
Published: January 2025

Accurate mapping of rubber plantations is essential to understanding where deforestation due to rubber production occurs. Wang et al.1 produced 10-meter resolution maps of mature rubber with a reported high overall classification accuracy (OA = 0.95 ± 0.02), indicating that more than 4 million hectares of forests have been converted to rubber plantations in Southeast Asia and parts of China since 1993. However, we have serious concerns about the accuracy of these maps, as our analysis indicates that the area estimates by Wang et al.1 are significantly inflated. This observation underscores the need for caution in using these high-resolution maps for specific applications, such as assessing deforestation linked to rubber consumption under the EU regulation on deforestation-free products.

Authors: Wang Ruiping , Duan zhen , Ding Yuning
Published: January 2025

BACKGROUND

Atopic dermatitis (AD) is a chronic, relapsing skin condition that significantly impact patients' quality of life. In clinical practice, AD is commonly managed through the use of emollients and topical corticosteroids. Haidebao body lotion (HBL) with the incorporation of Calcium-based antimicrobial peptide compounds (CAPCS) has demonstrated clinical benefits for patients with mild AD, but lack of high quality clinical trial evidence.

OBJECTIVE

In this study, we will implement a multi-center, double blind, randomized and placebo controlled trial to evaluate the efficacy and safety of HBL incorporated with CAPCS as an adjunctive therapy in ameliorating mild AD.

METHODS

This multi-center, randomized, double blind, placebo controlled trial will recruit 200 eligible participants in ten hospitals in China from October, 2023 to October, 2025. In this study, AD is confirmed in accordance with the Williams diagnostic criteria, and AD patients aged 18-55 years with the signed informed consent forms will be recruited. However, AD patients with pregnancy, serious underlying diseases, with communication barriers, and the violation of medication regulations will be excluded. In this study, 200 AD patients will be randomly assigned (1:1) to the treatment group (HBL with CAPCS, n=100) and the control group (HBL without CAPCS, placebo, n=100), and each participants in both groups will receive 3 sessions of treatments per day for 4 weeks. The primary outcome is the proportion of patients who has achieved at least 60% improvement in eczema area and severity index (EASI) score from baseline to week 2. The secondary outcomes include the numeric rating scale (NRS), dermatology life quality index (DLQI) at week 2 and week 4, and the adherence and adverse events will also be recorded. The full analysis set (FAS) and perprotocol set (PPS) will be analyzed by SAS 9.3 software package, and a P value less than 0.05 is considered as statistically significant.

RESULTS

This study is reviewed and approved by the Institutional Ethics Review Committee of Shanghai Skin Diseases Hospital in 2023 (2023-33), the participant recruitment work begins in January, 2024 and is proposed to be finished in December, 2024. This study was submitted for registration in Chinese Clinical Trial Registry on May 8, 2024, and approved on July 24, 2024. The registration number is ChiCTR2400087274. The study will be conducted in strict accordance with the Declaration of Helsinki.

CONCLUSIONS

This study will evaluate the clinical efficacy and safety of HBL incorporated with CAPCS in the treatment of patients with mild AD. If the treatment efficacy is proven, HBL incorporated with CAPCS could be clinically used as an adjunctive therapy in ameliorating mild AD.

Published: January 2025

Key Points

More tools are needed to explore upstream drivers of racial and ethnic disparities in kidney disease outcomes.

The Centers for Disease Control and Prevention Environmental Justice Index is a new tool which characterizes cumulative social and environmental burden at the census tract level.

This study is the first application of the Environmental Justice Index to understanding glomerular disease outcomes.

Background

The Centers for Disease Control and Prevention Environmental Justice Index Social-Environmental Ranking (EJI-SER) combines a Social Vulnerability Module with an Environmental Burden Module to characterize cumulative environmental and social burden at the census tract level. This analysis evaluates the association between EJI-SER and kidney outcomes in patients with glomerular disease (GD).

Methods

Cure Glomerulopathy is an observational cohort study of adults and children with biopsy-proven GD. EJI-SER is a percentile ranking by census tract, with a higher score indicating a more severe burden. Associations between EJI-SER and its components with kidney failure (initiation of KRT, transplant, or two eGFRs <15 ml/min per 1.73 m2) and longitudinal eGFR were tested using multivariable Cox regression and linear mixed models, respectively, adjusted for demographics, histologic diagnosis, eGFR and urine protein to creatinine ratio at enrollment, and time from biopsy to enrollment.

Results

Among 1149 participants with census tract data, the median (interquartile range [IQR]) follow-up was 5.4 (3.0–7.0) years, the median (IQR) age at biopsy was 24 (10–48), and self-identified racial distribution was 5% Asian, 18% Black, and 70% White. Median (IQR) EJI-SER was 0.49 (0.26–0.75). EJI-SER scores in the lowest two quartiles were associated with a lower hazard of kidney failure compared with the highest quartile (adjusted hazard ratio [95% confidence interval], 0.62 [0.36 to 1.08] and 0.43 [0.25 to 0.76] for EJI-SER 0%–25% and >25%–50% versus >75%, respectively) and higher eGFR at enrolllment (adjusted mean 90.1 versus 87.1 ml/min per 1.73 m2 for 0%–25% versus >75%, P = 0.08).

Conclusions

As captured by EJI-SER, higher environmental and social burdens are associated with lower eGFR and a higher risk of kidney failure in the Cure Glomerulopathy cohort. This first use of the EJI-SER in GD demonstrates the need for additional investigation into social drivers of disparities in GD and policies and resources that address these structural inequities.

Authors: Sayed Manzer Tasfiya  , Shabaray. R.A  , Nayak A Lathika
Published: January 2025

Main objective of this study was to list out the recent advancement in radionuclide therapy.Cancer rates are increasing globally at a rapid pace. This trend is influenced by a combination of factors, including the aging and expansionof the population, as well as shifts in the prevalence and distribution of key cancer risk factors.Current cancer treatments, such as surgery and external beam radiotherapy, become less effective once a tumor has spread. Targeted radionuclide therapy (TRT) uses radio-labeled biologics or other carriers to precisely deliver a cytotoxic dose of radiation to inoperable or metastatic cancer, emitting Auger electrons, β-particles, or α-particles.β-particle-emitting RPT agents have highly promising clinical and preclinical preliminary results with RPT agents using other α-particle-emitting radionuclides has reignited interest in RPT.Recent advancements in radionuclide therapies have shown promising results in various cancers. Astatine-211 (211At) has demonstrated potential in treating paraganglioma, acute leukemia, and thyroid cancer. 225Ac-DOTATATE has shown promise for gastroenteropancreatic neuroendocrine tumors. Bismuth-213 (213Bi) and Lead-212 have also shown positive results in treating different cancers, including small lung cancer. Boron neutron capture therapy (BNCT), recently FDA-approved, has improved outcomes in head and neck cancer. Additionally, nanomaterials are being used to deliver radionuclides more effectively, enhancing treatment precision and patient outcomes.
In conclusion there is a wide advancement in radionuclide therapy in today’s world and preparing for the future therapies. Radionuclide therapy is a door for the multitude of cancers and thus is a potential treatment option for those with advanced cancers and failed established therapeutics.

Authors: Oda Tetsuaki , Oda Chikako , Kanegae Yumi
Published: January 2025

This study investigates the effects of a three-month online exercise and nutritional guidance program on two groupsof elderly individuals in Japan: healthy elderly persons and those requiring nursing care. Conducted against the backdrop of Japan'saging population and the heightened risks of frailty during the COVID-19 pandemic, the study aims to enhance elderly welfarethrough supportive community initiatives and technological interventions. Participants from both groups engaged in structuredonline exercise routines and received tailored nutritional guidance. Physical abilities were measured before and after the programusing grip strength, one-leg stand, 5-meter walk, Timed Up and Go (TUG), and functional reach tests. The study utilized t-testsand correlation analyses to evaluate the changes in these measurements and assess the program's effectiveness. Results indicatesignificant improvements in walking speed and balance for the healthy elderly group, evidenced by decreased times in the 5-meterwalk and TUG tests. Although grip strength increased and functional reach decreased in this group, these changes were notstatistically significant. For the elderly requiring nursing care, significant improvements were observed in functional reach,suggesting enhanced physical flexibility, while grip strength showed a slight but not significant decline. Feedback from participantshighlighted high satisfaction with the program, improved exercise habits, and increased motivation, particularly among thoserequiring nursing care. The study underscores the potential of tele-exercise to reduce social isolation and promote health inelderly populations, advocating for the continued use and development of such interventions to foster a sustainable, healthorientedcommunity for the elderly in Japan.
Inferences based on type-I censoring competing risks data of power hazard rate models in the presence of partially observed causes of failure

Published: January 2025

When population units fail for several reasons, the competing risks model is
triggered. The failure time and associated reason of failure are noted in
this model. It is possible to partially observe the reasons why the
competing risks model fails. In this work, where the failure time is
distributed with the power hazard rate distribution, we utilize the
competing risks model under partially observed reasons of failure. We
develop maximum likelihood estimators of the model parameters with related
estimated confidence intervals based on the independent type-I censoring
competing risks data. Two distinct approaches are used to construct the
bootstrap point estimate and associated bootstrap confidence ranges.
Analysis is done using actual type-I competing risks data that has some
failure causes missing at random.

Published: January 2025

Objectives

To evaluate nasal septum changes after rapid maxillary expansion (RME) during the mixed dentition and to verify the association between quantitative and qualitative assessments of nasal septum deviation (NSD) by ear, nose, and throat (ENT) specialists.

Materials and Methods

The sample comprised 24 patients (11 male, 13 female) with a mean age of 7.62 ± 0.92 years with maxillary transverse deficiencies. Cone-beam computed tomography (CBCT) images were obtained before and after RME. Three CBCT coronal sections passing through the maxillary first molars, 5 mm anterior and 5 mm posterior, were used for quantitative assessment. NSD was calculated using the ratio of nasal cavity height to nasal septum contour. Additionally, five ENT professionals evaluated NSD qualitatively using scores from 1 to 3 through CBCT sequential axial and coronal sections. Absent NSD was scored as zero. Interstage changes were assessed using Wilcoxon tests. Spearman correlation and linear regression were performed to evaluate the association between quantitative and qualitative analyses (P < .05).

Results

No significant change was observed in the NSD ratio. In pre-expansion CBCT images, absence of NSD and scores 1, 2, and 3 for NSD were found for 45.8%, 41.7%, 12.5%, and 0%, respectively. In the qualitative assessment, no significant change in NSD was observed after expansion. A strong association was found between NSD ratio and ENT score (r = 0.750).

Conclusions

In the mixed dentition, no significant change was observed in the NSD ratio. Qualitative analysis of NSD was associated with quantitative assessment of the ratio between nasal septum contour and nasal cavity height.

Este trabalho explora a intersecção entre as políticas de saúde, parasitologia e saúde ambiental em comunidades indígenas brasileiras, destacando os desafios e oportunidades presentes nesse contexto. Por meio de uma pesquisa bibliográfica, buscou-se compreender as lacunas existentes na aplicação de políticas públicas voltadas à saúde dessas populações, com ênfase nos impactos relacionados à infraestrutura, como a ausência de saneamento básico e acesso à água potável. Foram analisadas as dificuldades de integração entre a medicina tradicional indígena e a medicina ocidental, que frequentemente limitam a eficácia das intervenções de saúde, além de apontar a necessidade de formação de profissionais interculturais, capacitados para lidar com as especificidades culturais dessas comunidades, e da participação ativa das lideranças indígenas no planejamento das políticas. O conceito de "Saúde Única" é apresentado como uma abordagem promissora para garantir a saúde integrada dessas comunidades, considerando os aspectos humanos, animais e ambientais de forma holística. As conclusões do estudo indicam que o fortalecimento da colaboração entre comunidades indígenas, governo e instituições de pesquisa é essencial para o desenvolvimento de soluções duradouras, culturalmente sensíveis e sustentáveis. Ressalta-se que a integração entre práticas tradicionais e modernas, associada ao investimento em infraestrutura e educação em saúde, pode promover melhorias significativas na qualidade de vida das comunidades indígenas e contribuir para a equidade no acesso à saúde.

Authors: Silva Marcelo Camacho , Villardi Raquel Marques
Published: January 2025

Este artigo analisa os pareceres emitidos pela Câmara de Educação Superior (CES) do Conselho Nacional de Educação (CNE) no período de 2001 a 2004, com foco nas questões relativas à avaliação e regulação da educação superior no Brasil. A partir de uma pesquisa documental e de uma análise de conteúdo, o artigo identifica as concepções, os argumentos, os critérios e as implicações das decisões da CES para a qualidade e a democratização da educação superior no país. Os resultados indicam que os pareceres da CES apresentam limitações e inconsistências teóricas, metodológicas e normativas, que comprometem sua legitimidade e eficácia como instrumentos de avaliação e regulação. Além disso, os pareceres revelam uma tendência à flexibilização e à desregulamentação das normas educacionais, favorecendo os interesses do mercado em detrimento dos princípios constitucionais e legais que regem o sistema educacional brasileiro. O artigo conclui que é necessário um aprofundamento do debate sobre o papel e o funcionamento do CNE, bem como uma maior participação e controle social sobre suas atividades, visando aprimorar a qualidade e a transparência de suas deliberações.

Participaram da pesquisa 62 graduandos de cursos de enfermagem, com idades entre 18 e 34 anos. A maioria estava no nono semestre e se sentia apta a atuar em casos de parada cardiorrespiratória. Contudo, identificaram-se dificuldades no manuseio do Desfibrilador Automático Externo, sugerindo a necessidade de mais ações práticas. Embora referirem-se aptos a atender uma parada cardiorrespiratória, observou-se algumas lacunas no conhecimento dos graduandos acerca da ressuscitação cardiopulmonar. Recomenda-se mais exercícios práticos, incluindo atividades complementares, para qualificar a formação acadêmica e garantir eficiência no atendimento emergencial.

Este estudo realiza uma avaliação da eficácia dos métodos de classificação por pixel GEOBIA na identificação do uso e cobertura do solo em áreas urbanas. Utilizamos dados provenientes dos satélites Landsat 8, Sentinel-2 e WorldView-2, que foram processados na plataforma Google Earth Engine, aproveitando sua capacidade de processamento em nuvem e acesso a extensos conjuntos de dados geoespaciais. Para verificar a acurácia das classificações realizadas, aplicamos técnicas de validação cruzada e holdout, permitindo uma avaliação robusta e confiável dos resultados obtidos. Os resultados indicam que a abordagem por pixel apresenta maior precisão quando aplicada a imagens de alta resolução espacial, como as fornecidas pelo satélite WorldView-2, devido à sua capacidade de capturar detalhes finos do ambiente urbano. Por outro lado, a metodologia GEOBIA demonstrou ser mais eficaz na identificação de padrões texturais e estruturais complexos, especialmente em áreas urbanas densas onde a heterogeneidade é elevada. Essa técnica se beneficia da segmentação de imagens e da análise baseada em objetos, permitindo uma classificação mais contextualizada e precisa dos diferentes tipos de uso e cobertura do solo.
Seurantatutkimus suomalaisten suhtautumisesta HIV-infektioon
Authors: Tikkanen Jorma , Koskela Kaj
Published: January 2025

Suomalaisten tietojen, asenteiden ja käyttäytymisen muuttumista HIV-infektioon tutkittiin vuosina 1986–1990. Vuonna 1986 aineiston muodostivat 1013 ja vuosina 1987–1990 noin 1900 15–64-vuotiaasta satunnaisotannalla koko maasta valitusta henkilöstä. Heidät haastateltiin henkilökohtaisesti tai puhelimitse strukturoidun haastattelulomakkeen avulla.
Tiedot HIV-infektion tartuntatavoista, HIV-testimenetelmistä ja testauspaikoista olivat tarkasteltuna ajanjaksona hyvät. Tiedot joistakin HIV-viruksen tartuntatavoista näyttivät paranevan vuosina 1986–1990. Pakkotestien kannattavien osuus väheni samanaikaisesti, kun vapaaehtoista HIV-testiä kannattavien osuus lisääntyi. Sitä vastoin käsitykset joidenkin erityisryhmien testaamisen tarpeellisuudesta pysyivät ennallaan. HIV-infektion uhkan kokeminen pysyi muuttumattomana kaikilla eri seurantakerroilla. Myöskään merkittäviä seksuaalikäyttäytymisen muutoksia suhteessa HIV-infektioon ei havaittu.
Tutkimuksen perusteella pääteltiin, ettei suomalaisten suhtautumisessa HIV-infektioon ole tapahtunut vuosina 1986–1990 huomattavia muutoksia. HIV-infektioon liittyvät käsitykset ja asenteet voivat siten olla suomalaisilla verrattain pysyviä.

Authors: Arinen Sirkka-Sisko , Sintonen Harri , Rosenqvist Gunnar
Published: January 2025

Tämä tutkimus on osaprojekti, jonka tavoitteena on selvittää nuorten aikuisten hammashuoltopalvelujen käyttöä ja vuonna 1986 voimaantulleen subventiouudistuksen vaikutusta siihen. Käyttöä mitataan hoitoon hakeutumisella ja käyntimäärillä. Aineisto kerättiin kyselyllä ennen uudistusta vuoden 1985 lopulla ja uudistuksen jälkeen vuoden 1987 lopulla satunnaisotoksilta, jotka kattoivat 19-26/27-vuotiaan väestön neljällä tarjontaolosuhteiltaan erilaisella paikkakunnalla (molemmilla kerroilla n = 2250). Vaiheittaisen mallituksen perusteella valittiin analyysimenetelmäksi kaksiosainen malli, joka koostuu binomiaalisesta logitmallista ja 0-katkaistusta, negatiiviseen binomijakaumaan perustuvasta regressiosta. Terveyden kysynnän taloudellisesta mallista johdetut muuttujat selittivät hyvin hoitoon hakeutumista, mutta suhteellisen huonosti hoitoon hakeutuneiden käyntimääriä. Uudistus muutti hoitoon hakeutuneiden käyntimääriin vaikuttavien tekijöiden suhteellista merkitystä. Subventiouudistuksen seurauksena hoitoon hakeutuminen lisääntyi noin 15 % ja hoitoon hakeutuneiden keskimääräinen käyntimäärä laski 17 %.

Governance challenges and strategic opportunities for implementing circular economy in greenhouse horticulture: A case study from the Netherlands
Authors: Batlles-delaFuente Ana , Franco-García Maria Laura , Castillo-Díaz Francisco José , Belmonte-Ureña Luis J.
Published: January 2025

Research background: Circular economy is promoted as a sustainable and efficient economic model in all industries. In the European agricultural sector, and particularly in greenhouse horticulture, its implementation presents both substantial opportunities and significant challenges that must be addressed effectively. The European Union's Common Agricultural Policy (CAP) has the potential to act as a critical catalyst for the adoption of circular economy through its subsidy and support mechanisms. However, progress remains constrained by a lack of comprehensive information on how governance can effectively advance circular economy in different countries and sectors. This gap persists due to the failure to identify several key aspects, and current CAP mechanisms do not adequately address these issues, thereby limiting their effectiveness in promoting a circular economy.
Purpose of the article: To identify key government actors influencing the implementation of circular economy in Dutch greenhouse horticulture, assess the transformative potential of their initiatives and evaluate factors that hinder or facilitate progress.
Methods: A review of the scientific literature, application of the Governance Assessment Tool (GAT), and validation of the results by key stakeholders involved.
Findings & value added: By applying the GAT, this article offers a detailed assessment of the governance dimensions affecting the implementation of circular economy in greenhouse horticulture in the Netherlands. The research reveals that effective governance is crucial for coordinating and collaborating among various involved stakeholders, such as producers, cooperatives, and auxiliary industries. The challenges highlighted include the lack of consensus among market actors and the need for more coherent policies. Currently, strategic opportunities are identified to improve implementation, such as strengthening public policies and promoting investments in sustainable technologies. Evaluation of these governance dimensions allows for determining where to focus time and resources to advance the implementation of circular economy, transforming current limitations into opportunities to support and enhance the transition process.
Socioeconomic and technical factors in European agricultural sustainable waste management: The case of Spain
Authors: García-Agüero Ana Isabel , Castillo-Díaz Francisco José , Belmonte-Ureña Luis J. , Camacho-Ferre Francisco
Published: January 2025

Research background: Inadequate management of agricultural waste is a growing challenge that poses significant risks to the environmental sustainability of ecosystems due to the lack of detailed information on how socioeconomic factors influence the management of such waste. The importance of addressing this issue is reflected in various European policies, such as Directives 2018/851 and 2018/852. However, current initiatives do not sufficiently consider the factors that affect producers' behavior in terms of waste management, limiting the effectiveness of these policies in improving the sustainability of the sector.
Purpose of the article: This study seeks to identify and analyze the technical, economic, and social factors shaping agricultural waste management practices among farmers and livestock producers. It also proposes policy and organizational recommendations that could serve as benchmarks. Spain, a key player in the European agri-food sector, serves as a case study.
Methods: Data were collected through a structured survey targeting Spanish agricultural and livestock producers, focusing on socioeconomic, technical, and waste management practices. Spain’s primary production system was selected as a representative European case due to its pivotal role in agricultural and livestock output. The survey, distributed via agri-food cooperatives and digital knowledge-sharing platforms, garnered 396 valid responses, achieving a 95% confidence level and a maximum margin of error of 2.2%. The dataset was analyzed using binary logistic regression to estimate the likelihood of effective waste management based on selected explanatory variables.
Findings & value added: The findings highlight that economic factors such as the volume of farm income directly and significantly influence waste management, indicating that higher income favors better management. Other influential factors are of a social nature: level of education, gender and age of producers. This research underscores the urgent need for tailored policy interventions to address these factors, advocating for enhanced waste management initiatives, specialized training programs, and collaborative advisory services in partnership with cooperatives and industry stakeholders.
