Published: September 2024

Nghiên cứu được tiến hành với mục tiêu mô tả sự hỗ trợ của chồng khi vợ mắc đái tháo đường thai kỳ (ĐTĐTK). Nghiên cứu định tính với cuộc phỏng vấn sâu về dân tộc học thực hiện trên 21 phụ nữ được chẩn đoán mắc ĐTĐTK sinh sống tại tỉnh Thái Bình. Kết quả cho thấy phần lớn thai phụ nhận được sự hỗ trợ của chồng khi mắc ĐTĐTK. Sự hỗ trợ đó có thể chia thành 3 lĩnh vực chính bao gồm hỗ trợ về mặt tinh thần (14/21 thai phụ); hỗ trợ về mặt thể chất (15/21 thai phụ); và tìm kiếm thông tin về ĐTĐTK (6/21 thai phụ). Một số phụ nữ xúc động trước sự hỗ trợ của chồng, trong khi những phụ nữ khác bày tỏ mong muốn được chồng hỗ trợ nhiều hơn. Vì vậy, nên hệ thống hóa việc chăm sóc thai kì, tạo điều kiện và thúc đẩy sự tham gia của chồng, nâng cao vai trò của hỗ trợ xã hội đối với phụ nữ trong thời kì mang thai, đặc biệt là phụ nữ mắc ĐTĐTK.

Abstract: The research paper introduced improvements to PeeCheck, a portable urine analyzer, addressing the need for versatile, rapid, and low-cost urine analysis tools, particularly in resource-constrained rural healthcare settings. The focus was on evaluating the accuracy and speed of reading the urine strip and the electrical characteristics of the portable urine analyzer device across various parameters. PeeCheck 2.0 represented enhancements in medical diagnostics using urine as a non-invasive sample. By incorporating the integration of technologies such as versatility in using variations of urine strips and data cloud storage using the Raspberry Pi Pico W microcontroller, PeeCheck 2.0 was designed to analyze 14 colorimetric urine characteristics, aiding in the pre-diagnostic of health issues associated with kidney and metabolic-related diseases. The study evaluated PeeCheck 2.0's performance through the analysis of urine samples collected from 3rd- and 4th-year electrical engineering students and compared the results with those obtained from standard laboratory urinalysis. The findings highlighted PeeCheck 2.0's potential to enhance health outcomes and reduce healthcare disparities in rural communities by providing healthcare providers with a low-cost and reliable solution for rapid detection and addressing health concerns in areas with limited resources. The study findings demonstrated that PeeCheck 2.0 achieved significant accuracy and speed in analyzing urine samples across 10 colorimetric parameters compared to standard laboratory methods. PeeCheck 2.0 obtained an overall accuracy of 92.470 percent in its analyses. Results from the evaluation with urine samples collected from electrical engineering students showed a high correlation with laboratory urinalysis, validating PeeCheck 2.0's efficacy in detecting key indicators of kidney and metabolic-related diseases. However, continuous programming-based calibration optimized PeeCheck 2.0 by adjusting parameters in real-time with data and sensor feedback, ensuring consistent accuracy and reliability in urine parameter testing. This research underscored PeeCheck 2.0's role in advancing medical diagnostics through innovation in urine analysis technology, contributing to improved healthcare delivery and outcomes in rural and underserved communities.

Published: September 2024

This study introduces an innovative method for assessing the economic value of carbon stored by the urban park forest in Quito, Ecuador. The method uses Sentinel-2 remote sensing data and advanced deep learning techniques. A large forest study area was chosen, and detailed field measurements were taken to gather biomass and carbon data. Sentinel-2 satellite images were processed to correct for radiation and atmospheric conditions, and vegetation indices such as NDVI and EVI were calculated. To model forest biomass, a convolutional neural network (CNN) was created and trained using Sentinel-2 spectral bands and vegetation indices. The model was validated with independent field data and demonstrated high accuracy in estimating biomass and carbon, as indicated by evaluation metrics like RMSE and R². The findings include detailed maps showing the spatial distribution of biomass and carbon in the study area, which can be a valuable tool for forest management and the implementation of policies for valuing stored carbon. This approach combines the high resolution of Sentinel-2 data with the predictive power of neural networks, providing a robust and scalable method for estimating carbon across large forest areas. The study's conclusions emphasize the feasibility and accuracy of this approach and its potential for application in various forestry and geographical contexts.

The Size Distributions of Faults and Earthquakes: Implications for Orogen-Internal Seismogenic Deformation
Authors: Truttmann Sandro , Diehl Tobias , Herwegh Marco , Wiemer Stefan
Published: September 2024

Abstract. Pre-existing geological discontinuities such as faults represent structural and mechanical discontinuities in rocks which influence earthquake processes. As earthquakes occur in the subsurface, seismogenic reactivation of pre-existing fault networks is difficult to investigate in natural settings. However, it is well-known that there exists a physical link between both faults and earthquakes since an earthquake’s magnitude is related to the ruptured fault area and therefore fault length. Furthermore, faults and earthquakes exhibit similar statistical properties, as their size distributions follow power laws. In this study, we exploit the relation between the size distributions of faults and earthquakes to decipher the seismic deformation processes within the exhumation-related orogen-internal setting of the Southwestern Swiss Alps, which due to its well-monitored seismic activity and the excellent outcrop conditions provides an ideal study site. Characterizing the size distribution of exhumed fault networks from different tectonic units based on multi-scale drone-based mapping, we find that power law exponents of 3D fault networks generally range between 3 and 3.6. Comparing these values with the depth-dependent exponents of estimated earthquake rupture lengths, we observe significantly larger values of 5 to 8 for earthquake ruptures at shallow depths (< 3 km below sea level (BSL)). At intermediate crustal depths (~3 to 9 km BSL), the power law exponents of faults and earthquakes appear to be similar. These findings imply depth-dependent differences in the seismogenic reactivation of pre-existing faults in the study region: while partial rupturing is the prevailing deformation mechanism at shallow depths, faults are more likely to rupture along their entire length at intermediate crustal depths. Therefore, the present-day near surface differential stresses are likely insufficient to rupture entire pre-existing faults seismogenically. Our findings have direct implications for seismic hazard considerations, as earthquakes that rupture along entire faults appear to become less likely with decreasing depth.
Unlocking the Power of Parallel Computing: GPU technologies for Ocean Forecasting
Authors: Porter Andrew , Heimbach Patrick
Published: September 2024

Abstract. Operational ocean forecasting systems are complex engines that must execute ocean models with high performance to provide timely products and datasets. Significant computational resources are then needed to run high-fidelity models and, historically, technological evolution of microprocessors has constrained data parallel scientific computation. Today, GPUs offer an additional and valuable source of computing power to the traditional CPU-based machines: the exploitation of thousands of threads can significantly accelerate the execution of many models, ranging from traditional HPC workloads of finite-difference/volume/element modelling through to the training of deep neural networks used in machine learning and artificial intelligence. Despite the advantages, GPU usage in ocean forecasting is still limited due to the legacy of CPU-based model implementations and the intrinsic complexity of porting core models to GPU architectures. This review explores the potential use of GPU in ocean forecasting and how the computational characteristics of ocean models can influence the suitability of GPU architectures for the execution of the overall value chain: it discusses the current approaches to code (and performance) portability, from CPU to GPU, differentiating among tools that perform code-transformation, easing the adaptation of Fortran code for GPU execution (like PSyclone) or direct use of OpenACC directives (like ICON-O), to adoption of specific frameworks that facilitate the management of parallel execution across different architectures.

Published: September 2024

The national R&D system is a concept that has gained significant recognition; however, measuring it is challenging and not devoid of difficulties. In this paper the method of composite variables is applied to configure R&D systems and with this examines their characteristics and subsequent impact on fostering greater innovation by studying a group of OECD countries. Starting with many variables, 31 variables were selected for the second step and used in a factor analysis to create composite indicators or unobservable abstract variables. Each variable’s assignment to a single factor is clear, allowing the identification of five distinct and interpretable factors. Subsequently, a knowledge production function was estimated, considering a technological outcome of the R&D systems as the dependent variable; another function was configured reflecting the scientific output. Finally, an additional model was estimated, using productivity as the dependent variable. In all models, the National R&D Effort and Innovative Firms Factor emerged as the most significant variable, underscoring the importance of reaching certain thresholds in terms of available human and physical resources for carrying out innovative efforts within an R&D system.

Authors: Ferré-Pavia Carme , Silva Aguilar Andre´s
Published: September 2024

El objetivo de este artículo es examinar las narrativas digitales sobre la inmigración de Venezuela entre los y las usuarias colombianas. Para ello, se analiza el debate político sobre este colectivo en la plataforma X/Twitter en Colombia. La muestra está conformada por los tuits que fueron categorizados según una tipología de encuadres genéricos y específicos diseñada para este análisis de contenido. De un corpus de 160.095 tuits con hashtags sobre esta migración, se filtraron 15.703 tuits originales. Los resultados sugieren la pervivencia de la polarización respecto a los tipos de encuadre utilizados. Los de tipo genérico responden a ejes temáticos; los específicos, a mensajes que encuadran mayoritariamente a los migrantes como víctimas de un conflicto o crisis humanitaria (25 % y 17,3 %). Quienes los sitúan en el frame de la amenaza fiscal o del orden público suman un 26,7 %. Los datos obtenidos apuntan a que es esencial promover un debate público informado y constructivo sobre la migración venezolana en Colombia. Esto implica, no solo abordar la desinformación y los discursos de odio, sino también proporcionar espacios para que las voces de los migrantes y las comunidades receptoras sean escuchadas y tenidas en cuenta en el debate público y en la toma de decisiones políticas.

Estamos en el Antropoceno: ¿Es el fin de los tiempos?
Authors: Schifter Secora Isaac , González Macías María del Carmen
Published: September 2024

En el año 2000 el Nobel de Química Paul Crutzen describió al Antropoceno como una propuesta para designar una nueva era geológica en la cual la humanidad era la protagonista, a raíz de que las actividades humanas han tenido un enorme impacto sobre el sistema terrestre en términos geológicos, biológicos y climáticos. Los científicos proponen, asimismo, marcadores útiles que dan cuenta del inicio del Antropoceno, los cuales incluyen carreteras, microplásticos, mercurio o los radionucleótidos. En los países industrializados, el transporte representa la segunda fuente de gases de efecto invernadero, después de la generación de electricidad. Una manera de mejorar la eficiencia automotriz es la de modificar la composición de las gasolinas. Al formular combustibles empleando componentes derivados de la biomasa, se obtienen carburantes de bajo contenido de carbono, con lo cual se disminuye la emisión de estos gases al tiempo que se mantiene un óptimo desempeño vehicular. Usualmente los biocombustibles líquidos se dividen en cuatro generaciones, dependiendo del material que se emplea en la transformación. La primera generación emplea materiales almidonados, tales como el azúcar de caña, que se transforman en alcohol. La segunda emplea biomasa lignocelulósica no comestible que se transforma en moléculas de azúcar y de ahí se derivan los combustibles. La tercera generación encuentra su fuente de producción en la biomasa del mar, la cual requiere menos área y es efectiva para la disminución de gases de efecto invernadero. La cuarta generación la constituyen la ingeniería metabólica y la genética. Considerando que el futuro es finito, así como las consecuencias de nuestras acciones como humanidad, podemos minimizar nuestros daños colaterales a la biosfera y maximizar las materias primas para la siguiente fase del planeta.
On GAYUF Transformed Exponential Distribution and its Properties
Authors: T. O. Yusuf, , A. S. Ajiboye, , A. A. Akomolafe,
Published: September 2024

In statistical literature, various methods exist for developing new distributions. This paper introduces a new distribution derived using the GAYUF transformation. We explore several structural properties of this distribution, including moments, moment generating function, mean, variance, hazard rate and its shape, survival function, and more. The parameters of the newly developed distribution are estimated using the maximum likelihood estimation (MLE) method and validated through simulation studies. Additionally, we apply the distribution to two real-world datasets to demonstrate its practical applications. The findings suggest that the new distribution is a robust tool for modelling and analysing data in engineering and other fields, providing enhanced fit and reliability for parameter estimation.

NPF requires a definite model of professional policing. Each nation operates on the model of its political transformation and experience. The dynamics of modern society require a new dimension in police operations and administration. Police duties are getting more volatile and assertive, and continuously evolving. In requiring police to provide protection, and safe environments, police must become better trained in processing and addressing potential risk, hence the need for professionalism. With the overwhelming criminal crisis in the country, the Nigeria Police Force (NPF) is challenged to arrest the situation and produce results, timely and technologically in line with social change. To set combative objectives, gain control of the security environment and deliver on their constitutional mandate, the MBO principle of shared objectives and professionalism of the police is hereby suggested. The ‘General Duty’ (GD) and ‘Specialist’ (S) model of policing practice have to be done away with.

Recently, we have been increasingly encountering terms such as turbulent environment, dynamic environment, unstable environment, and businesses must be prepared to respond flexibly to challenges arising from such an environment. The competitiveness of companies depends more and more on the rapid adaptation to ongoing changes. The sources of basic competitive advantages are efficiency, quality, innovation, full understanding, and sensitivity to customer requirements. The main driving force behind innovation is adequate research and development. Research and development represent one of the steps towards innovation and the innovative activity of companies. The aim of the paper is to evaluate the innovative activity of small and medium-sized enterprises in the Slovak Republic as the basis of the company's competitive advantage based on selected indicators. Subsequently, we will analyze and evaluate the use of human resources within the innovative activities of the company and in research and development in individual regions of the Slovak Republic.

The Indonesian government currently focuses on high infrastructure development to prepare for connectivity between one city and another. The massive construction of the new government capital is also called the archipelago's capital. This condition impacts companies supporting construction projects, which are growing rapidly. This growth is supported by corporate governance and the cash-holding industry, which supports infrastructure projects for the company's financial performance. This research aims to determine the role of cash holding and corporate governance (board skill, independent director, managerial ownership) on the financial performance of infrastructure-supporting manufacturing companies in Indonesia. The sample used in this research was 83 manufacturing companies listed on the Indonesia Stock Exchange in the 2010-2020 period. This research uses panel data regression as a data analysis method. The results of this research show that managerial ownership significantly impacts increasing cash holding by maintaining the optimization of cash and cash equivalents. The company's managerial ownership cannot impact board skills because many companies still need to accommodate share ownership by management and board-skill-educated doctors. This condition also causes board size skills not to impact increasing cash holding in the company. Board skills have yet to be able to impact financial performance significantly. Managerial ownership and cash holding impact increasing return on assets, thereby increasing financial performance for manufacturing companies that support infrastructure projects. The independent director, as a variable moderator, still needs to be capable of moderating managerial ownership, board skill, and cash holding to improve financial performance. This condition is caused by data from several companies still needing more independent directors. Research provides a practical contribution to the owner as soon as possible, recruiting board members with doctoral education as competent board skills and making independent directors have a vital role in improving financial performance. The theoretical contribution to research is to enrich the theory of corporate governance and financial performance.

Within the context of the financial industry, the purpose of this research is to investigate the influence that management of scope, time, cost, and quality has on the performance of projects and business overall performance in the financial sector. Following the collection and examination of the study materials, a total of 331 samples were deemed appropriate for analysis by means of the PLS software. According to the findings, the implementation of scope, time, cost, and quality management has a direct and beneficial impact on the enhancement of project performance in the organization that deals with financial matters. As an additional point of interest, the project scope has a favorable impact on the performance of the project through the implementation of work breakdown structure, project scope definition, and scope change control. The formulation of a timetable, the estimation of the duration of activities, and the critical path analysis are all ways in which project time can have an impact on the performance of the project. Additionally, the cost of a project has an impact on the performance of the project through the processes of cost estimation, budgeting, and cost control. And finally, project quality effects positively on project performance and business overall performance through Based on the findings, it appears that the successful management of these four knowledge domains greatly improves the outcomes of the project. To be more specific, Scope Management ensures that the company's goals are aligned with the expectations of the organization, Time Management assists in meeting deadlines, Cost Management optimizes budgets, and Quality Management guarantees that high standards are maintained. Based on the findings of the study, it is concluded that combining these areas results in higher project performance, highlighting the crucial importance of these areas in projects involving the financial industry.

Fungal Phyllosticta capitalensis is reported to produce secondary metabolites with important bioactivities, i.e., antibacterial and antioxidant. This is the first time that the fungal P. capitalensis has been isolated from Andrographis paniculata twigs. Secondary metabolites isolation from the extract of the fungus P. capitalensis was performed using several techniques of chromatography, i.e., vacuum liquid chromatography and column chromatography, to obtain two pure compounds (1 and 2). Both compounds were determined for their structures using analyzing data of spectroscopy of NMR and FT-IR. Based on the analysis, compounds 1 and 2 were ergosterol and ergosterol peroxide, respectively. Both steroids were evaluated for their bioactivities following agar dilution method for antibacterial activity. Compound 2 was more active against three bacterial strains than compound 1. Based on the structure-activity relationship, presence of peroxide in C-5 and C-8 increases the bioactivity of ergosterol derivatives. Interestingly, herein, ergosterol peroxide (2) is firstly reported f from fungal P. capitalensis.
