Published: July 2024

Health, Safety, and Environmental (HSE) standards are indispensable in industrial operations, safeguarding workers, protecting the environment, and ensuring operational efficiency. This paper comprehensively reviews HSE standards, focusing on their historical evolution, key components, implementation challenges, and future directions. The historical evolution section traces the development of HSE standards, from early regulatory responses to industrial hazards to establishing integrated frameworks encompassing health, safety, and environmental considerations. Key components of HSE standards include health standards addressing occupational health risks, safety protocols emphasizing accident prevention and emergency response, and environmental standards regulating pollution control and waste management. Integrated HSE management systems promote synergy across these domains, enhancing operational resilience. Challenges in implementing HSE standards are multifaceted, ranging from regulatory compliance issues and technological barriers to organizational cultural and economic constraints. Overcoming these challenges requires concerted efforts to enhance regulatory frameworks, adopt innovative technologies, foster a safety culture, and balance economic considerations with HSE commitments. Future directions in HSE practices emphasize AI, IoT, and digitalization innovations to enhance real-time monitoring and predictive capabilities. Policy recommendations focus on strengthening regulatory frameworks and promoting proactive approaches to HSE governance. Organizational strategies highlight the role of leadership, employee engagement, and continuous improvement in fostering a culture of safety and environmental stewardship. In conclusion, advancing HSE standards is crucial for promoting sustainable industrial practices and ensuring the well-being of workers and the environment. Embracing these standards mitigates risks and enhances operational efficiency and corporate responsibility in a rapidly evolving global landscape.

Published: July 2024

The study assessed the efficiency of tomato production and market concentration among farmers in Orire Local Government, Ogbomoso, Oyo State, Nigeria, employing a multi-stage sampling technique, resulting in a sample size of 120 respondents. A structured questionnaire developed by the researcher was utilized as the research instrument. Analysis was conducted using descriptive statistics, budgetary techniques, the Herfindahl-Hirschman Index (HHI), and the Cobb-Douglas production model. Findings revealed that 76.7% of respondents were male, with an average age of 52.6 years. Additionally, 89.2% were married, and 69.2% had formal education. The average household size was 5.4, with an average farm size of 4.3 hectares. Respondents had an average of 16.4 years of experience in tomato production. The cost and return analysis indicated that tomato production is profitable in the study area, with a return on investment of N1.71, meaning every 1 naira invested yields a return of N1.71 kobo. The market concentration index was 1325, suggesting competitive market conditions. The Cobb-Douglas model identified key factors influencing production efficiency: education, household size, farm size, farming experience, credit access, seeds, fertilizer, pesticides, and herbicides. The study recommends that financial institutions offer affordable credit facilities and that agricultural extension services and post-harvest practice workshops be provided to enhance farmer incomes and reduce tomato waste.

Published: July 2024

Currently, there is a financial crisis affecting commercial banks in Kenya occasioned by high levels of loan loss provision as a result of Non-Performing Loans. The past decade has seen the collapse of major banks like Chase Bank among others.  This trend on Non-Performing Loans of the institutions requires urgent measures to reverse failure to which the entire sector is likely to collapse, and customers would lose a significant amount of their deposits.  This study sought to investigate the effect of credit risk and liquidity risk on non-performing loans (NPLs) of commercial banks in Kenya and appraise the moderating effect of firm age on the relationship between financial risk exposure on non-performing loans of commercial banks in Kenya. The study was underpinned by liquidity preference theory. The examination adopted a positivist paradigm guided by explanatory research design. The study targeted 40 commercial banks as the unit of analysis while branch managers, operations and risk managers were the units of observation drawn from the banks adding to 120 respondents and census was used. The study collected both primary data using structured questionnaire on the independent variable and secondary data from publications by Central Bank of Kenya (CBK) and respective banks and the same was analyzed through the statistical package for social sciences (SPSS) version 26 in a descriptive and inferential manner.  The study established that credit risk (p<0.05) and liquidity risk (p<0.05) were all found to have significant effect on NPLs of commercial banks in Kenya and significantly moderated by their sizes. It was concluded that financial risk exposure has significant effect on NPLs of commercial banks in Kenya. It was recommended that finance manages working in commercial banks in Kenya to balance the investment in short term and long-term assets to maintain operational liquidity levels for better management of liquidity risks. Credit managers working for commercial banks in Kenya need to review the existing credit risk management efforts and mechanisms to minimize exposure to NPLs.

Published: July 2024

A doença do refluxo gastroesofágico (DRGE) é uma condição altamente prevalente, caracterizada pelo retorno do conteúdo ácido do estômago para o esôfago devido ao mau funcionamento do esfíncter esofágico inferior. Isso resulta em sintomas frequentes como queimação retroesternal, regurgitação ácida, dor no peito e dificuldade para engolir. Uma complicação grave associada à DRGE é o esôfago de Barrett (EB), onde ocorre a metaplasia intestinal do tecido esofágico, aumentando substancialmente o risco de desenvolvimento de câncer esofágico. Fatores de risco como obesidade, tabagismo, consumo de álcool e dietas ricas em alimentos gordurosos e condimentados são frequentemente associados ao desenvolvimento dessas condições. O diagnóstico preciso geralmente envolve endoscopia com biópsia, permitindo a identificação de alterações histológicas como a metaplasia intestinal. O tratamento abrange uma abordagem multifacetada, incluindo terapia medicamentosa com inibidores da bomba de prótons e ajustes no estilo de vida, como perda de peso, dieta controlada e mudanças nos hábitos alimentares. Em casos mais severos, procedimentos endoscópicos ou cirurgia podem ser necessários para controlar os sintomas e prevenir complicações futuras, destacando a importância de uma abordagem multidisciplinar para melhorar a qualidade de vida dos pacientes e reduzir o risco de progressão para câncer.

Authors: Ferreira Micaelly Rodrigues , Betti Andresa Heemann
Published: July 2024

O Transtorno do Espectro Autista (TEA) é caracterizado por danos no desenvolvimento neurológico, manifestando-se em comportamentos repetitivos e déficits na comunicação e interação social. Seus tratamentos são limitados, muitas vezes recorrendo a medicamentos com eficácia limitada e potenciais efeitos colaterais. O objetivo deste trabalho foi realizar uma revisão bibliográfica sobre os efeitos do canabidiol (CBD) no tratamento de sintomas do TEA. Para tanto, foi realizada uma revisão bibliográfica a partir de estudos de caso, observacionais sem grupo controle e randomizados duplo cego contra placebo. De maneira geral, os estudos analisados demonstraram resultados promissores, evidenciando uma melhora substancial em diversos sintomas relevantes associados ao TEA, acompanhada de uma baixa incidência de efeitos adversos. Contudo, destaca-se a limitação destes estudos em relação à variação dos métodos adotados para avaliar os resultados, as proporções de CBD e Tetrahidrocanabinol (THC) nos extratos utilizados, tempo de tratamento e tamanho amostral. Portanto, torna-se imprescindível a realização de mais estudos conduzidos de maneira padronizada em relação à duração do tratamento, extratos utilizados e emprego de questionários validados.

O presente estudo trata-se de um estado do conhecimento acerca da produção científica sobre relações de gênero e Educação Profissional (EP) na plataforma SciELO. Para tanto, a metodologia empregada compreende a seleção dos artigos que discutem esses temas, bem como a análise através da Análise Textual Discursiva (ATD) de Moraes e Galiazzi (2006). Foram utilizadas duas ferramentas para facilitar o processo de seleção e análise dos artigos: o gerenciador de referências Zotero e o aplicativo web Rayyan. Os dados obtidos com esse estudo revelam que há uma falha no que diz respeito a igualdade com que a SciELO abarca periódicos, já que a maioria dos artigos encontrados são provenientes do sudeste, centro-oeste e sul do Brasil. Além disso, nos mostra que a maioria dos artigos escritos sobre relações de gênero e educação são de autoria feminina. Por fim, fica evidente a necessidade de produzir mais sobre relações de gênero a fim de enfraquecer progressivamente os determinismos existentes em nossa sociedade em razão do sexo biológico dos sujeitos.

Published: July 2024

Insufficient liquidity can become a significant obstacle to stock trading and impede the smooth operation and performance of the stock market. This motivated the study to investigate the effect of stock market liquidity on stock market performance in Nigeria. The research design employed was ex post facto, while stratified sampling technique was used to select top 30 actively traded and most liquid companies tagged NGX-30 for this study. Data were sourced secondarily from SEC Statistical Bulletin, CBN Statistical Bulletin and www.investing.com. The Vector Error Correction (VEC) System Equation Regression was employed as the estimation technique. The results revealed that liquidity depth, liquidity breadth, and liquidity immediacy have significant positive effects on stock market performance as shown by ? = 0.2019, 8.5594, 3.3268; p-value = 0.0329, 0.0052, 0.0467 respectively. Also, interest rate, inflation rate and exchange rate have varied significant effects on stock market performance as shown by ? = -0.0023, -1.1738, 0.03432; p-value = 0.0634, 0.0346, 0.0778 respectively. Therefore, the study concluded that stock liquid significantly affects stock market performance. Thus, the study recommended that the Security and Exchange Commission (SEC) should implement policies that encourage the participation of more traders to increase the number of actively traded stocks; support measures that improve the depth of the market by promoting transparency and fairness; improve the infrastructure for trade execution to enhance liquidity immediacy; and develop mechanisms to promptly identify and mitigate market risks.
UNDERSTANDING THE SPANISH ENERGY MARKET IN 2022 WITH AN ANALYSIS OF OFICIAL DATA
Authors: GARCIA BRINGAS PABLO , DOMINGUEZ PESQUERA GUILLERMO
Published: July 2024

The energy situation that occurred in the Spanish electricity and natural gas markets in 2022 implies the concept of a global crisis. This entails a significant increase in the prices of electricity and natural gas. Historically, the relationship between these two concepts has always been substantial, as demonstrated in the conducted study.
This article aims to analyze whether this relationship between both markets has continued to be strong in the past year, 2022, and to assess the factors that may have distorted the results. To achieve this, publicly available data recorded by various operators in the electricity and natural gas markets have been meticulously analyzed and reviewed from a statistical-mathematical perspective.
The study investigates the implications of the rising prices of electricity and natural gas, as well as the measures taken by the Spanish Government in June 2022.
Furthermore, it is essential to consider that in 2022, several anomalous factors occurred, such as the Russia-Ukraine war and the Spanish market intervention resulting from the price increases, suggesting a different market behavior.
The primary conclusion drawn from the analysis of the published data is that the high prices in 2022 can be attributed not solely to the high prices of natural gas, as indicated in the media. This will be elaborated upon throughout this study.

Key Words: Gas Cap Adjustment Mechanism, Massive Consumption of natural gas and exports of electricity in 2022. Correlation between OMIE and MIBGAS.

In the development of new Wave Energy Converters it is advisable, prior to their design, to carry out a study of the waves in order to check whether the device is going to be able to generate electricity. Furthermore, knowing the swell in the area will help the design of the collector to adapt it to the type of swell. The aim of this study is to find out the main wave parameters of the Spanish Atlantic coast, specifically in Galicia, the Basque Country, Andalusia and the Canary Islands. After comparing the 4 locations, a detailed study of the ideal location will have to be carried out in which, in addition to the frequency of occurrence of the swell and the direction of the swell, the slope of the swell and the power per metre of wave front will have to be detailed, as well as the maximum power that could be extracted from the device to be designed.

Published: July 2024

Nowadays, the digitisation of products occupies a very significant space in the product market, as incorporating new functionalities means satisfying new needs for users. Likewise, there is a debate between the programmed obsolescence of products that use technology within their useful life. This work aims to connect the benefits provided by technology within products by projecting a proposal that has a longer useful life thanks to the adaptation of the product to the user.
It deals with the design of children's furniture, an intelligent cot, which adjusts to the needs of the first stage of life by including sensors and components that improve the baby's rest, and which, in turn, incorporates modularity in its design to be able to adapt to the following stages of the child's life up to the age of 12.
The proposed methodology incorporates a series of methods and techniques that provide a 5-phase structure that includes a group of experts who work transversally in the product design process to strengthen decision-making and prioritisation of the needs raised.
Several alternatives are developed and, thanks to the evaluation based on the needs extracted at the beginning of the process together with the design requirements, the one that best satisfies both areas is chosen.

Early detection of skin cancer is quite important since some types, such as melanoma, are dangerous and even it can cause the death if are not properly and early treated. Here, deep learning is broadly used to implement non-invasive systems for diagnosing skin cancer based on image analysis. In this work, it is presented a model, which is a derivation of the Visual Geometry Group with 16-layer deep model architecture (VGG16), for implementing a benign keratosis (bkl), melanocytic nevi (nv) and melanoma (mel) skin cancer classifier. Moreover, it is shown that by using a balanced dataset an average classification accuracy of 79.94% for the three types of cancer can be reached. Furthermore, it is presented this accuracy is quite competitive compared when the same skin cancer classifier is implemented by using the VGG16, the ResNet50v2, and the InceptionV3 pre-trained models, since the obtained average accuracies were 78.32%, 79.40% and 81.03%, respectively, under the same conditions. Additionally, it is described that the proposed model is lighter compared with the mentioned pre-trained models since it requires of 1.4 million of trainable parameters. Finally, it is shown that this characteristic contributes to the computational processing time for implementing, training, and evaluating the skin cancer classifier when the proposed model is used. Based on these numerical results, it is shown that the proposed model is competitive in terms of the required number of trainable parameters and the overall processing time in comparison with the required by the mentioned pretrained models without penalizing the skin cancer classification metrics.

Published: July 2024

In regions where winter temperatures fall below the tolerable thermal limits for crops, it is necessary to implement emergent equipment to supply heat inside the greenhouse. The objective of this work was to evaluate numerically the effect of two heating systems and crop size on the thermal gradient inside the greenhouse. This work aimed to estimate the thermal gradient generated by the heating system as a function of the age (height) of a greenhouse tomato crop. Temperature prediction was carried out using a numerical model based on Computational Fluid Dynamics (CFD), the impact of each heating system was examined, as well as the influence of crop size on thermal homogenization. The results indicate that when using electric heaters, the temperature at 1.5 m above the ground increases in the simulated no-crop scenario. As the crop size increases, the temperature at 1.5 m from the ground decreases (difference of up to 8 °C between the scenario with and without 2 m crop). Suggests that the crop, acting as a porous medium (barrier), reduces the energy exchange between the top of the greenhouse and the crop zone. However, when having a pipe heating system, the temperature at 1.5 m from the ground is more homogeneous, and the simulated scenario with the highest temperature is the one where the crop size is the largest (2 m) with a thermal difference of up to 1.5 °C between the scenario with and without 2 m crop. In summary, we have a larger thermal difference between the simulated scenarios when using electric heaters. However, electric heaters are still the best option to increase the greenhouse temperature, increasing the air temperature by up to 3 °C in the worst simulated scenario compared to the piped system.

Keywords: Simulation; CFD; tomato growth; thermal homogenization; thermal comfort.
EMPOWERING ENERGY COMMUNITIES: THREE METHODS TO DISTRIBUTE SAVINGS IN LOCAL ENERGY MARKETS
Authors: GONZALEZ ASENJO DAVID , IZQUIERDO LUIS , SEDANO FRANCO JAVIER
Published: July 2024

In the current context of energy crisis, the energy sector is undergoing significant transformations towards a sustainable, competitive, and affordable energy landscape. Central to this transformation are Energy Communities (ECs), which have emerged as an ideal vehicle to facilitate the energy transition for small consumers.
This paper evaluates the performance of three alternative methods (i.e. bill-sharing, price-based and surplus-based) to allocate costs and benefits within ECs. Specifically, we compare the distribution of savings generated by energy internal trading under each of the three allocation methods.
The three allocation methods guarantee extracting the maximum economic surplus (i.e. savings) from the internal market, but one of them (bill-sharing) does not guarantee that participating in the internal trading is beneficial for every member. This is a major obstacle for its implementation since, frequently, some agents are worse off due to its participation in the community. The other two methods guarantee that participation is beneficial, but they differ in how savings are distributed. The distribution under price-based methods is influenced by the prices at which different members of the EC can buy and sell energy from the grid, while surplus-based methods distribute savings according to a criterion agreed by the EC members. Here we assume that they do it proportionally to the energy traded in the internal market.

Keywords: energy communities, local energy market, allocation method

The excellent tribological properties of copper are well known, which is why it is commonly used in components whose tribological characteristics have a high impact. Thanks to the characteristics of Additive Manufacturing it is possible to manufacture parts incorporating copper particles. However, the main mechanical studies are related to performance under tensile-compression or bending conditions and the tribological properties are still little studied and this means that there is no knowledge of the possible performance of parts obtained using additive techniques with these particles. For this reason, this article proposes to carry out a study on a polymeric Additive Manufacturing process, specifically, Fused Filament Manufacturing, which is the most widely used process at present and where it is possible to obtain thermoplastic matrix filaments with different types of reinforcements. In this case, a reinforcement of metallic nature will be chosen, such as copper particles, where the properties of this material will be exploited. The aim is to find out how the basic manufacturing parameters, layer thickness and temperature, influence the tribological behaviour of the parts obtained with this process.

Vaginal delivery assisted with forceps (FAVD) is an obstetric technique that involves the extraction of the fetus by traction and/or expansion of the birth canal with an instrument. Currently, the use of forceps allows for the resolution of pathological situations that would otherwise require a cesarean section with the risks of morbidity and mortality that this surgery entails. For this reason, there is a growing interest in increasing the percentage of FAVD, after obstetricians feel more confident after practicing in simulation workshops with mannequins and acquiring the necessary competencies for their correct use.
The forceps is an instrument that requires a precise introduction and placement, so an electromagnetic tracking tool has been developed that knows, with high precision, the position of the instrument both inside the vagina and around the fetal head. With this, childbirth training is complemented by a virtual simulation, in real-time, that allows the internal position of the forceps to be seen, thus facilitating the learning and improvement of the introduction and placement technique. For this, the instrument must not contain any ferrous residue that interferes electromagnetically, so commercial forceps (made of stainless steel) are not valid. In this context, the reproduction of forceps has been proposed through additive manufacturing based on material extrusion (MEX). To obtain forceps that are as realistic as possible in terms of rigidity compared to commercial models, a nylon filament reinforced with carbon microfibers (Onyx) has been used to which continuous carbon fiber is added in successive layers. Given the limitations in the printing volume of the technology used (Mark Two), numerical simulations were carried out by finite element analysis and different proposals for dividing each piece and subsequent union by adhesives were made, finally developing the final solution.

This work presents an approach to the detection of catastrophic tool breakage in automatic drilling processes that take place during the assembly phase of aeronautical structural components.
During the drilling phase, fuselage components are arranged in hybrid stacks, including carbon fiber composite and titanium alloy. Machining conditions vary along each drilling operation depending on the material and number of components, their thicknesses, cutting parameters, the cooling and/or lubrication system, and workpiece clamping.
In the machining process of these hybrid stacks, the level of complexity can lead to critical conditions that result in catastrophic tool failure. This scenario is particularly problematic due to the cost and time involved, especially in automatic processes.
To detect the moment when these events occur in real-time, a detection method based on the time-frequency domain analysis of the main spindle power consumption signals is proposed. Specifically, the feasibility of using the Haar, Daubechies, Symlet and Coiflet discrete wavelet transforms with different decomposition levels is studied to detect breakages considering signals corresponding to a 4.6 mm diameter tool in the production system.

DESIGN AND EVALUATION OF A LOW COST BIOMETRIC TIME TRACKING SYSTEM

Published: July 2024

Employee time tracking is sometimes an issue for many companies for two reasons. First, the lack of convenient devices. Second, the reluctance of employees. This is particularly noticeable in situations where employees do not work within corporate facilities, making it difficult to track work hours. Recent regulations by governments have emphasized the need for accurate time tracking, creating uncertainty in business environments. This paper proposes a simple and cost-effective time tracking system using the Asterisk PBX that runs on commodity hardware. This allows employees to track their working time without additional devices and regardless their locations. This solution uses an interactive voice menu, so employees may record actions related to their daily activities (start and end of the workday, etc.). The employee calls the Asterisk PBX and utters a passphrase before recording the action. Then, a biometric module analyzes the employee's voice to verify their identity, preventing impersonation. The verification process is independent of the text (IT), so the passphrases given to employees have no constraints. The results of the tests performed on the system indicate an accuracy of 99.7%, demonstrating the reliability of the biometric module. High values of accuracy (99.89) and recall (99.8%) are also obtained. Thus, the identification of legitimate employees and fraudulent identification attempts are very accurate.

One of the bad decisions made by a developer is the lack of a good encapsulation in the design pattern "Template Method", when this happens, "Code Smell" appears, which is defined as "symptoms of poor design and implementation choices", these symptoms will be reflected in a high degree of dependency between classes of a program (indirect coupling), thus shortening the lifetime of the software.

Industry 4.0 has led to a change in the execution of the production process, in which robotics is the key instrument for improving efficiency. All this means obligates human beings to adapt to the new procedures, and for this reason the industry is moving towards Industry 5.0, where human-machine relations become the key to research and improvement. Therefore, the aim of this work is to identify the main fields of science study that has justified patents linked to Human-Robot Interaction. For this purpose, a dataset that identifies the scholarly works that represent the non-patent literature of the patents in question has been identified and data mining and network analysis techniques have been applied. The results define Computer Science, Artificial Intelligence, Robots, Simulation and Engineering as the most influential, published mainly in high quality technical journals associated to the area. Therefore, it can be concluded that the fields of study of the non-patent literature are progressively developing new fields associated to four main knowledge clusters, which, in terms of scientific quality, brings robustness to the technological developments linked to Human-Robot Interaction

Universities are distinguished by their wide range of high quality services. These services are aimed at members of the teaching and research staff and administrative and service staff, as well as students and even the general public. Universities have tried to apply quality principles in their daily work. The principles (customer orientation, continuous improvement and teamwork) can be seen as rules or norms of behaviour that guide action generally and universally in today's universities. They must be thoroughly practised and known in order to achieve the best possible application of this corporate philosophy.
SEVERITY OF TRAFFIC ACCIDENTS ON HORIZONTAL CURVES AND THEIR DETERMINANTS: A BAYESIAN NETWORK AND INFORMATION THEORY MODEL
Authors: Sun Tao , Zhang Zhan , Lu Linjun
Published: July 2024

Statistical analysis reveals that the unique environment of horizontal curve roads significantly contributes to the severity and fatality rates of traffic accidents. This study leveraged accident data from the Florida Department of Transportation (FDOT) to explore the severity of traffic accidents on horizontal curves and its influencing factors. Bayesian network was combined with information theory for the analysis of the severity and determinants of accidents on horizontal curves from the perspectives of network topology, the strength of the relationship between influencing factors, and the pathways of influencing factors. Results show that, (1) Traffic accident causation is complex, with a hierarchical network structure of factors rather than direct impacts from individual variables. (2) The strength of the relationship and dynamic change correlation between each variable are obtained. Results demonstrate that accidents are rarely caused by a single factor, and the severity of traffic accidents can be prevented and reduced by controlling variables states.(3) The analysis of the influence pathways of uncontrollable variables, like weather, revealed specific state combinations (e.g., Fog+Slippery, Rain+Slippery, Fog+Wet) that significantly escalate accident severity. This study presents an advanced model for predicting and diagnosing traffic accidents on horizontal curves, offering insights into the causative factors and their quantitative relationships and influence pathways.
