Published: March 2024

Abstract
Additive manufacturing (AM) has come to the fore in recent years among manufacturing techniques. This technique, which has different advantages than traditional ones such as casting, forging and machining, is expected to be widely used in producing machine parts like gears in the coming years. Therefore, experimental data on AM parameters for lightweight metal gears are important for industrial production. In this study, a wear test was applied to AlSi10Mg and Ti6Al4V gears under operational conditions, and the wear behaviour of conventionally and additively manufactured gears was compared. The amount of abrasion elements was determined by analysing the oil in the gearbox. In addition, gear surfaces were analysed using scanning electron microscopy and an energy-dispersive spectrometer before and after wear. Thus, the wear behaviour of gears produced by conventional and AM under service conditions was demonstrated comparatively.

Published: March 2024

Abstract
In this study the effect of T6 heat treatment, two-step aging treatment and ultrasonic impact peening on the exfoliation corrosion behavior of welded EN AW 7020 was investigated. Exfoliation tests were performed according to the ASTM G34-01 standard. As expected, as a result of the tests, the base material region of all three samples were showed better corrosion resistance than the heat-affected region. Ultrasonic impact peening and two-step aging treatment was observed that improved EXCO sensitivity in the weld area. When sorting was made by considering the resistance to corrosion of the heat affected zone of the samples, it was observed that the best resistance was shown by the sample with two-step aging treatment, and the worst resistance was shown by the sample with T6 heat treatment.

Abstract
China’s annual production of ceramic tiles inevitably produces a large amount of ceramic tile waste, which causes environmental and land occupation problems. Using a high-volume ceramic tile waste to fabricate ultra high performance concrete (UHPC) will reduce the workability and mechanical properties but increase the low-carbon properties. Motivated by such mechanical and low-carbon properties, this study introduced inexpensive, spherical, low-carbon nano-CaCO3 (NC) to improve the workability and mechanical properties of UHPC with a high volume of ceramic tile waste powder and aggregate (UHPCHCTWPA). The results of this study indicated that NC can improve the workability but shortened the setting times of UHPCHCTWPA. NC also significantly increases the mechanical properties including compressive strength, compressive work, flexural strength, fracture energy, and ratio of flexural strength to compressive strength. It is due to that NC enhances the hydration rate and hydration degree, and optimizes hydration product orientation, size, and distribution. Moreover, compared with UHPC, the UHPCHCTWPA with NC reduces energy intensity, CO2 emission, and cost by more than 20%. Therefore, adding NC can make UHPCHCTWPA with good workability, mechanical and low-carbon properties and can effectively and quickly utilize ceramic tile waste.

Published: March 2024

Abstract
The realm of cancer therapy has been profoundly altered with the emergence of immune checkpoint blockade (ICB) therapy, providing improved survival prospects for many patients with some cancers. However, the challenge of achieving efficient or sustained therapeutic benefits underscores the critical imperative to optimize ICB strategies. This review elucidates the pivotal role of predictive biomarkers in optimizing precision ICB therapy, deciphering the intricate dynamics associated with the response heterogeneity. Furthermore, it critically examines the application of nanotechnology-driven drug delivery as a promising avenue to amplify ICB efficacy, facilitating controlled and targeted drug release. Recognizing the comprehensive and dynamic interplay among tumor cells, immune cells, and stromal cells has catalyzed the transformative advances in reverse translational research. This approach enables researchers to gain insights into the underlying mechanisms of ICB therapy, therapeutic responses, and resistance mechanisms. The convergence of predictive biomarkers, revolutionary nanotechnology, and reverse translational research emerges as an indispensable focal point, propelling the frontiers of precision oncology within the complex landscape of ICB therapy.
Environmental Regulation Intensity and Low-Carbon Technology Progress in the Context of the Internet of Things
Authors: Lin Lin , Lan Wei 
Published: March 2024

Abstract
Whether the intensity of environmental regulation affects the progress of low-carbon technology is an important issue faced by the development of low-carbon economy in the new era. From a macro perspective, this article selects panel data from 30 provincial-level administrative regions in China from 2000 to 2009 for analysis. The impact and mechanism of environmental regulation intensity on low-carbon technological progress are analyzed. The empirical results indicate that the increase in environmental regulation intensity has significantly promoted the progress of low-carbon technology in the region. The subsample test shows that this effect is greater in the eastern region than in the central and western regions, but there is no significant difference in the impact of environmental regulatory intensity on the progress of the two types of low-carbon technologies. The mechanism test shows that regional labor costs research and development capabilities have moderating effects on the above effects. These low-carbon technologies have been widely applied in various fields of the Internet of Things.
Physician Workforce in Kansas: Where are the Orthopedic Surgeons?
Authors: Hughes Dorothy , Reese Derek , Templeton Kim 
Published: March 2024

Introduction. Rural patients have greater need but less access to orthopedic surgical care than their urban counterparts. Previous studies have investigated rural surgical care, but this is the first to assess the Kansas orthopedic surgery workforce to identify changes over time and rurality and inform thinking about future workforce composition.
Methods. The authors analyzed 2009 and 2019 AMA MasterFile and Area Health Resource File (AHRF) data. Using frequencies, percentages, and calculations of orthopedic surgeons per capita, we assessed workforce changes by rurality (Rural Urban Continuum Codes).
Results. The dataset included 307 orthopedic surgeons; 197 were in both 2009 and 2019. Of these, 165 were in active practice in 2009 and 244 in 2019, an increase of 79 (47.9%). Kansas had smaller proportions of surgeons in rural (non-metro) versus urban (metro) counties in both years. Orthopedic surgeons per capita grew throughout the state, but the increase was smaller in rural counties. There were 11 women orthopedic surgeons in both years, 3.6% of the total 307. Among the 197 surgeons in both years, four (2.0%) were women. No women orthopedic surgeons were in non-metro counties either year.
Conclusions. Although the Kansas orthopedic surgery workforce grew from 2009 to 2019, rural Kansas remains a surgery desert based on orthopedic surgeons per capita. Further studies could determine whether this trend is similar to that in other rural states and how to attract orthopedic surgeons to rural practice.

Abstract
Objectives
Disparities in colorectal cancer (CRC) screening uptake by socioeconomic status have been observed in Canada. We used the OncoSim-Colorectal model to evaluate the health and economic outcomes associated with increasing the participation rates of CRC screening programs to 60% among Canadians in different income quintiles.

Methods
Baseline CRC screening participation rates were obtained from the 2017 Canadian Community Health Survey. The survey participants were categorized into income quintiles using their reported household income and 2016 Canadian Census income quintile thresholds. Within each quintile, the participation rate was the proportion of respondents aged 50–74 who reported having had a fecal test in the past two years. Using the OncoSim-Colorectal model, we simulated an increase in CRC screening uptake to 60% across income quintiles to assess the effects on CRC incidence, mortality, and associated economic costs from 2024 to 2073.

Results
Increasing CRC screening participation rates to 60% across all income quintiles would prevent 69,100 CRC cases and 36,600 CRC deaths over 50 years. The improvement of clinical outcomes would also translate to increased person-years and health-adjusted person-years. The largest impact was observed in the lowest income group, with 22,200 cases and 11,700 deaths prevented over 50 years. Increased participation could lead to higher screening costs ($121 million CAD more per year) and lower treatments costs ($95 million CAD less per year), averaged over the period 2024–2073.

Conclusion
Increased screening participation will improve clinical outcomes across all income groups while alleviating associated treatment costs. The benefits of increased participation will be strongest among the lowest income quintile.
Interpretación judicial de las leyes de acción positiva en los casos de violencia de género
Authors: Ochoa Díaz Angélica , Chacín Fuenmayor Ronald 
Published: March 2024

El artículo tiene como propósito analizar el razonamiento judicial frente a las leyes de acción positiva en lo que r­especta a la función del juez como aplicador del derecho, quien tiene un margen de discrecionalidad como todo intérprete judicial, además de razones morales referidas a su libertad de conciencia y la posibilidad de efectuar estas facultades frente a las leyes de acción positiva, concretamente las que protegen a las mujeres frente a la violencia de género como prima facie vinculantes, por estar relacionadas con la protección de los derechos de las minorías, consagrados constitucionalmente. La metodología consiste en el estudio de diferentes documentos escritos, tales como libros, artículos de revistas, documentos científicos, legislación, jurisprudencia, entre otros. La originalidad y aporte se centró en expresar la problemática sobre la limitación o no del razonamiento judicial frente a las leyes de acción positiva. Par el logro del objetivo se plantearon estos aspectos: nociones sobre la violencia de género, la interpretación jurídica en general y, por último, análisis de las leyes de acción positiva y su interpretación. A manera de conclusión es importante resaltar que, el ciudadano y los organismos del estado están sometidos a la carta magna y al ordenamiento jurídico por lo que no es posible el derecho de objeción de conciencia y el margen de discrecionalidad que tiene el juez como todo intérprete judicial en los casos de violencia de género, aunque esto contravenga a la concepción moderna del derecho en cuanto a la jurisprudencia como fuente creadora de derecho.

Published: March 2024

Background: As one of the most expensive sections of health system, hospitals are of special importance among healthcare service providers, and the management of financial resources in this sector is essential for continuous provision of services. The high cost of the burn department and post-treatment care in the armed forces, which is one of the most needed units of this organization, has led to the financial analysis of the burn department in Chamran Hospital. The main goal of this study is for the policy-makers and managers of the country's health sector to adopt a suitable policy in the debate between quality and cost-effectiveness of establishing a burn unit in the field of health and treatment, so that, in addition to reducing the costs of this sector, they focus on positive external effects, including reducing the psychological pressure on the affected people.
Methods: This cross-sectional and descriptive study analyzed burn department in one of the hospitals affiliated with the armed forces in 2020 and 2021. The required data was collected through the review of all the hospital financial statements and patient payment documents during the period under study, and the income, cost and profitability indicators were calculated and analyzed using Excel software.
Results: Based on the results, the calculated costs in the burn department were more than 62 billion tomans, and the income from hospitalization of patients was about 61 billion tomans. The index of pharmaceutical income to total income was calculated as 0.35, pharmaceutical income to pharmaceutical cost was 0.10, and the ratio of hoteling income to total income was 0.37. Among the cost indicators, the ratio of the cost of medicine and medical supplies to the total costs was 0.31, the energy cost to the total cost was 0.002, the percentage of personnel cost to the total resources was 0.56. Moreover, the profitability index was calculated as 0.97.

Conclusion: According to the results, although the burn department, especially in the armed forces, is not cost-efficient from an economic point of view, from a social point of view and due to the health and treatment mission of the armed forces, which is the efficient support of the armed forces and meeting their needs. Establishing this sector is considered a strategic matter and the optimal use of resources and reduction of unnecessary costs is necessary for cost efficiency. Therefore, the establishment of a systematic system for evaluating financial performance, outsourcing services, providing subsidies, and raising burn tariffs in order to improve the performance of the burn department in government hospitals are the methods proposed in this study to improve financial indicators, productivity, and excellent management in providing services to the patients in the burn department.

Background: The supply chain of hospital services is a relatively new and highly challenging field, and it is crucial for relevant officials to possess the necessary skills. The success in this domain relies on the characteristics of managers, their management practices, and their leadership style. This study aims to investigate the requirements of management and leadership in hospital services’ supply chain.
Methods: This study employed a two-stage mixed-methods approach carried out from 2018 to 2021. In the first stage, a qualitative study was conducted using purposive sampling and semi-structured in-depth interviews with 15 experts in various leadership positions. The data collected in this stage were analyzed using framework approach. Subsequently, the primary themes that emerged from the analysis were presented to 8 experts in the form of a questionnaire. The experts' responses were then analyzed to determine the level of agreement on different topics using Delphi method, Kendall's coefficient of agreement, and the mean was compared through SPSS 21.
Results: The experts identified transformationalism, planning capability, crisis management, and creativity as the most crucial factors. Furthermore, there was a high level of agreement regarding the influence of managers (4.62 ± 0.51), maintaining distance from mundane routines (4.50 ± 0.53), and attending to various incidents in hospital services supply chain (4.50 ± 0.53). Considering that Kendall Rank Correlation Coefficient (w) was 0.53 in the first round and 0.72 in the second round and was statistically significant, there was a strong consensus among the expert panel.
Conclusion: According to the results of the present study, it is necessary to pay serious attention to the change in management style and hospital services supply chain, there should be a special focus on the possibility of occurrence or impact of sudden accidents. Also, routine and ineffective actions should be eliminated and the managers and employees should be more creative to improve this chain. Transformational leaders should try to manage the hospital services supply chain by forming specialized teams and using the capabilities of employees with the reasonable use of financial resources and appropriate infrastructures, including information technology.
