Abstract
The EFSA process of Environmental Scanning and Strategic Options Definition aims at identifying knowledge gaps and opportunities to fulfil EFSA's mission more efficiently and contribute to the definition of EFSA's work programme and long‐term strategy. The identification of trends, drivers of change and emerging risks in the fields within EFSA's mission is one of the objectives of this process. The Member States and stakeholders in the EFSA knowledge networks for emerging risks, namely the Emerging Risks Exchange Network (EREN) and the Stakeholder Discussion Group on Emerging Risks (StaDG‐ER), have identified several emerging chemical issues/risks and analysed them according to the EFSA definition of emerging risks and characterisation criteria. In addition, various EFSA projects have been conducted for the identification of emerging chemical issues/risks using a wide range of methodologies and tools, like text and data mining, drivers’ analysis, foresight and chemical analysis (suspect screening, non‐target analysis). In these projects, a variety of specific emerging chemical issues/risks have been identified and drivers of emerging risks explored (climate change, blue economy, circular economy). This technical report provides an overview of EFSA's activities related to emerging chemicals in the period 2020‐2023. Identified emerging chemicals as well as the analysis of the strengths and weaknesses of the overall identification process in place, with a particular focus on its sustainability in the long term, are reported. In the context of the latest regulatory developments related to the set‐up of an early warning system for emerging chemicals, actions to maximise opportunities and minimise weaknesses are described. They focus on collaborative efforts with a wide range of organisations for a permanent and sustainable emerging chemical risks identification system and developments to support the exchange of information on emerging chemical risks via specialised platforms.

UNDERSTANDING THE PORTRAYAL OF TOXIC CHARACTERIZATION IN TAMIL CINEMA FROM A GENDER LENS
Authors: S. Shridevi , Jayalakshmi  , Raja N
Published: August 2024

The film is an integral part of human lives. The potential of film is beyond the functions of the mass media which are information, education and entertainment. The film media act as an agent of cultural transformation, shaping the perception, forming the ideologies and the like. Watching films with family, friends, and well-wishers has been a channel of emotional association. Watching films with family and friends gives us the liberty to explore our inner self and to share our views about the films and its content with each other. The concept of masculinity and feminity in films is not new but it has its roots in the context of gender and culture. This is a socio-cultural idea which conditions a man and woman with stereo-typical behaviours in order to fit in a predetermined cultural framework. The term toxic refers to the concepts which are harmful to the human wellbeing. This research throws light on the investigation of toxic masculinity and feminity traits and the understanding of these traits among the college going students through films. According to Live Mint (2022) It is revealed that, in the post pandemic period the frequency of theatre goers has increased. The young adults in the age group of 18-29 are the frequent film viewers. Based on the research articles, it is found that in India 15% of the people watch films in the theatre one time in a week. 8% of the people mentioned that they visit the theatre fifteen days once. Understanding the concept of toxic masculinity and feminity in films by the students is the need of the hour. Students are inculcated with the ideologies, behaviours, body language with what they see in the silver screen which subsequently is reflected in their relationships with friends and family members. In this regard, the researchers made an attempt to investigate these concepts from the student’s perspective.

Systems Thinking in Practice in a Circular Economy
Authors: Schaap Ainsley , McGowan Katharine
Published: August 2024

The Circular Economy (CE) is frequently touted as important for building sustainability. Despite growing interest in CE, few theories have provided effective on the-ground tools for building circularity. This case study of an agricultural organization in Western Canada illustrates how the logic of complexity helps frame and sustain a CE. Interviewees embraced complexity to manage the messy, unpredictable work of CE. Although preliminary, this suggests the possibility that circular economy-like behaviour may be more complex than currently understood. Interviewees represented complex systems thinkers in the wild and could help others seeking to build their own CE initiatives.

A Study on the Impact of Investor Sentiment on the Relationship between R&D Investment and Future Firm Performance
Authors:   Korea Accounting Information Association, Kwak Youngmin , Park Jinmo
Published: August 2024

[Purpose]The purpose of this study is to empirically verify whether the relationship between R&D expenditures and future performance varies based on the type of investor sentiment formed around individual companies at the time of R&D expenditure.
[Methodology]The study analyzes whether the relationship between R&D expenditure and future performance differs depending on the investor sentiment formed around individual firms at the time of the R&D investment. Investor sentiment at the individual firm level is defined using the methodology proposed by Ryu et al. (2018), and future firm performance is measured by both accounting－based metrics (ROA) and market－based metrics (Tobin’s Q). Specifically, an interaction term between R&D investment and investor sentiment is used to empirically analyze the effect of investor sentiment on the relationship between these two variables (i.e., R&D investments and future firm performance).
[Findings]First, optimistic investor sentiment leads to increased R&D expenditure by firms. Second, when investor sentiment is optimistic, the increased R&D expenditure negatively impacts future accounting performance and market value. Third, we confirmed that these results are consistently supported by Heckman’s two－stage analysis, which controls for the effects of latent endogenous variables. Collectively, these findings indicate that while optimistic (pessimistic) investor sentiment increases (decreases) R&D investments, these investments have a negative relationship with future firm performance. These results imply that R&D investments driven by investor sentiment may be suboptimal decisions carried out from a catering perspective rather than optimal investment decisions.
[Implications]This study expands the field of behavioral finance by exploring the influence of investor sentiment on corporate decision－making. Practically, it suggests that during periods of optimistic investor sentiment, investors should carefully analyze the information provided by firms. Additionally, firms should be cautious not to make suboptimal decisions influenced by favorable market conditions.

Published: August 2024

Introduction: For the 2020-2022 trieniumm more than 2 million cases of breast cancer were estimated worldwide. De novo metastatic breast cancer is so called when metastasis is diagnosed at the same time as the primary tumor. It affects approximately 3.5 to 10% of breast cancer patients and only 25% of these will be alive after 5 years. Methods: We conducted a retrospective cohort study of women with de novo metastatic breast cancer treated at a single center from January 1, 2000 to December 31, 2012. Cases were identified in the Hospital Cancer Registry. Overall survival (OS) was estimated at 5 years with the Kaplan-Meier product limit, and the log-rank test was used to test differences between curves; Cox multiple regression and all tests were considered significant with p<0.05. Results: Of the 265 patients in the study, the estimated 5-year OS was 31.3%. There was a difference in survival according to the following: age group (p<0.046); having had breast surgery (p<0.001); having undergone chemotherapy simultaneously with radiotherapy, hormone therapy, targeted therapy or surgery (p<0.088); use of exclusive or multimodal hormone therapy (p<0.001); education (p<0.001); luminal tumors (p<0.003); and being treated between 2006 and 2012 (p=0.043). In the multiple model adjusted by age group and education, the following factors remained as predictors of a better prognosis: having undergone surgery (hazard ratio — HR=0.46, 95% confidence interval — 95%CI 0.32–0.66); luminal tumors (HR=0.34, 95%CI 0.23–0.50); and targeted therapy (HR=0.27, 95%CI 0.15–0.46). Conclusion: The risk of death in patients with de novo metastatic breast cancer was lower than in those undergoing local surgical treatment as part of multimodal treatment, as well as the luminal molecular subtype and the introduction of better systemic treatment strategies, such as target.

Objective: In Brazil, the characteristics of breast cancer patients who arrive at cancer treatment services are influenced by conditions related to the tumor, to the diagnostic system and navigation in the phase prior to care, with regional differences being little known as well as their seasonal variation. Methods: This is a retrospective study of epidemiological data of patients with breast cancer treated at the Hospital do Câncer de Muriaé (HCM), an exclusively oncology hospital (CACON II), with primarily public care, a reference for cancer treatment in the east of Zona da Mata region, Minas Gerais. Clinical and care-related characteristics were evaluated from 2010 to 2021. Results: During this period, 4,573 new patients were treated. The care was primarily public (80.5%) and most patients were undiagnosed (45.7%) or untreated (71.8%) at the first visit. The patients were between 40 and 69 years old (70.2%) and a significant portion were between 70 and 74 years old (7.4%). The rate of early stage (clinical stage – CS 0 + I) represented only 33.9 and 25.8% of all patients and those treated exclusively in the hospital, respectively. There was no change in clinical stage and age group over the years. Conclusion: When evaluating epidemiological data, the characteristics of the service and the pre-institutional diagnostic care network should be analyzed, facts that influence the results. Throughout the period, there was no great variation in relation to age group and staging. In this region, the early stage of breast cancer has unsatisfactory rates, and the 70 to 74 age group should be considered in mammographic screening. Epidemiological studies are essential to improve health strategies.

Authors:   , Fernandes Daniel
Published: August 2024

Este estudo teve como objetivo identificar o tratamento contábil empregado aos ativos de concessão pelas empresas que aderiram ao processo de Relicitação. Foram levantadas as concessionárias que aderiram ao processo, analisados os seus termos aditivos de Relicitação e as suas demonstrações contábeis após a adesão, buscando compreender os direitos e obrigações relativas aos ativos de concessão. Foi desenvolvida uma árvore de decisão, com base nas Interpretações Técnicas aplicáveis aos ativos de concessão - ICPC-01 – Contratos de Concessão - e ICPC-17 – Contratos de Concessão – Evidenciação, e na Orientação Técnica OCPC-05 – Contratos de Concessão - considerando os estágios dos processos de Relicitação e qual o tratamento contábil empregado aos ativos de concessão por cada uma das concessionárias. O estudo revela que as concessões rodoviárias, em virtude da figura do excedente tarifário presente em seus termos aditivos e que representa um redutor ao valor da indenização, foram as únicas cujo modelo de concessão implicou transferir o ativo de concessão do ativo intangível para o ativo financeiro. As demais concessões que mantiveram o ativo de concessão no ativo intangível avaliam a recuperabilidade dos contratos considerando os recebimentos das indenizações em suas análises de impairment concomitantemente ao término do contrato, fato este que se apresenta como um indicativo de que estas estejam considerando estimativas otimistas de recebimento da indenização em suas análises de impairment. Diante desses achados, este estudo proporciona contribuições teóricas e práticas. Como contribuição teórica, destaca-se a abordagem multidisciplinar, considerando aspectos históricos, ao abordar as motivações das concessionárias para aderirem ao processo de Relicitação, assim como aspectos de natureza econômico-financeiro e jurídico sobre o tema, ao abordar como é elaborado um plano de exploração rodoviária, os agentes reguladores envolvidos e como a conjuntura econômica pode influenciar as operações de uma concessionária. Já como contribuição prática, o estudo apresenta uma árvore de decisão para auxiliar a administração a definir o tratamento contábil mais adequada de acordo com sua compreensão sobre o processo de Relicitação.

Published: August 2024

The exploration and exploitation of oil and gas resources have significant economic implications for host communities. However, the benefits often come with complex challenges, particularly in terms of ensuring equitable social development. This review examines the role of legal frameworks in balancing economic benefits with social equity in oil and gas regions. It explores how robust legal structures can ensure that the wealth generated from natural resources leads to sustainable and inclusive development for local populations. Key areas of focus include the allocation of resource revenues, environmental protection, and community engagement. Effective legal frameworks can mandate the distribution of resource revenues in a manner that prioritizes local development projects, thereby addressing infrastructural deficits and improving living standards. Moreover, environmental regulations within these frameworks are critical in mitigating the adverse effects of resource extraction, thereby preserving the health and livelihoods of host communities. The study also highlights the importance of participatory governance, where community stakeholders are actively involved in decision-making processes related to resource management. This involvement ensures that the interests and rights of local populations are considered and safeguarded. Case studies from various oil and gas regions illustrate the successes and failures of different legal approaches, offering valuable insights into best practices. Ultimately, the review argues that the alignment of economic and social objectives through comprehensive legal frameworks is essential for fostering harmonious and sustainable development in resource-rich regions. By balancing economic benefits with social equity, legal frameworks can transform the presence of oil and gas industries into a catalyst for positive change in host communities.
Contributions of Naira-USD, Naira-Franc and Naira-Yuan exchange rates on inflation and its volatility in Nigeria

Published: August 2024

The alarming increase in consumers goods and services with concurrent devaluations of naira have necessitated the need to examine the effects of NUSX(Nigerian naira/1 US dollar), NFX (Nigerian naira/1 France franc) and NCX (Nigerian naira/1 Chinese yuan) rates on inflation(measured by CPI) and its volatility in Nigeria using data sets spanning from 2008 to 2022. The auxiliary autoregressive AAR(3) order of integration test specify that all the variables are stationary at first difference. Adopting multiple regression model with least square method of estimation and generalized autoregressive conditional heteroskedasticity (GARCH(1, 1)) as measure of volatility, the results indicate that NCX (Nigerian naira/1 Chinese yuan), NFX (Nigerian naira/1 France franc) and NUSX(Nigerian naira/1 US dollar) have no influence on both inflation and its volatility in Nigeria. This implies that variation in exchange rates system is not sufficient to explain the sudden increase in the prices of goods and services in Nigeria. Therefore, the government should look beyond exchange rates in finding solution to rising inflation phenomenon in Nigeria’s economic space.

There is an ongoing effort to develop and improve the quality of briquettes, which could become an alternative fuel source. This can be achieved by exploring the utilization of raw materials like kerosene. The goal of this study is to analyze the convection and conduction processes occurring in the combustion of tree ferns. It is conducted to explore the use of tree ferns as a raw material for the production of briquettes. The prototype briquette made using tree ferns is characterized by a honeycomb design with 14 holes and a diameter of 20 cm. It is made using a mixture of 20% adhesive and 80% tree fern charcoal. The various factors that influence the combustion process include the initial temperature, the pot wall temperature, the environmental temperature, and the moisture content of the briquette. Different instruments such as anemometer, an infrared thermometer, a stopwatch, and a moisture meter are also used in the study. The study revealed that the tree fern briquette made from 14 holes exhibited a convection heat transfer power of 4302.444watts and a conduction heat transfer power of 5106.5watts. The efficiency of the two processes allowed the briquettes to burn for about 2 hours and 30 minutes, and they could sustain a moisture content of 12%. The study indicates that tree ferns can serve as an energy source alternative to kerosene. This presents a sustainable and eco-friendly way of meeting energy demands

The briquette mold is a critical component in the manufacturing process of the hydraulic briquette molding machine. Improved mold design can increase production efficiency and quality. The finite element method simulates the structural response of the briquette mold to hydraulic pressure. An accurate mathematical model is built based on material parameters, mold dimensions, and hydraulic load characteristics. The influence of mold design variables such as geometry, materials, and internal configuration can be evaluated in detail by applying FEM. Mold optimization uses a numerical optimization algorithm to find a combination of mold parameters that provides the best structural response. The main goal of mold optimization is to increase mold durability, reduce deformation, and minimize the potential for structural failure. The optimization process is integrated with FEM analysis to achieve the optimal mold solution. Improved mold design resulting from this optimization makes a positive contribution to the efficiency of hydraulic briquette production and reduces the potential for mold damage. The results of this research by optimizing the design of the length of the rod, length of the mold, height of the central protrusion of the press, and changing the diameter of the mold, we obtained simulation results that show an even distribution of loads shown in the same color. In this study, the total deformation value was 5.0298 x 10-6 mm and the equivalent elastic strain was 3.4972 x 10-10 mm

Indonesia has 377 MW of micro-hydro potential as an energy source for electric power generation, with the main component being water turbines. Important parameters controlled in electricity generation are generally the rotation and frequency of the turbine-generator which are regulated automatically in this case through a guide vane. This research explores the potential use of pneumatic control with an Arduino microcontroller as an alternative in regulating the Inlet Guide Valve (IGV) opening in a low-power Micro Hydro Power Plant (MHP). Hydraulic systems that are generally used in large power water turbines have constraints on maintenance costs and high processing time. By utilizing pneumatic control, this research uses Arduino to control the guide vane movement through a pneumatic cylinder. Tests were conducted with separate programs to read the turbine rotation, activate the solenoid valve, and adjust the power on the guide vane simulator. The test results show that the system successfully controls the rotation of the water turbine effectively. The conclusion of this research is that there is an inversely proportional relationship between the opening of the guide vane and the rotation of the water turbine, as well as successful control through a pneumatic system with Arduino. This research contributes to the development of low-power MHP technology with more efficient maintenance costs.

To face the planetary crisis, Indonesia has prioritized sustainable development through the use of green economy practices to reduce future carbon emissions. Solar energy as one of the renewable energy sources has greater value than others, but its utilisation is still small. Consideration of this condition is discussed with the aim of evaluating the progress of the green economy; finding problems; providing solutions and suggestions for Indonesia's future development. The research method uses a systematic quantitative descriptive approach based on data collected through observations, interviews and questionnaire surveys from resource persons by providing 3 leverage factors namely; funding, regulation and institutions. The study results show that the regression coefficient of the funding factor variable (X1) is 0.365 and positive, then the funding factor variable (X1) has the largest coefficient compared to the coefficient of the regulatory factor (X2) and the institutional factor (X3), so that the funding factor is the most dominant factor in measuring the performance of solar energy success towards the implementation of the green economy. Without serious support from the government in terms of funding readiness, development goals will not be achieved, due to the large amount of funds needed to support the development of the Green Economy. However, the three variables are mutually sustainable by making policies and legal foundations to fulfil the funding needs of the green economy, regulations will be the foundation in mainstreaming the implementation and funding of green economy policies. Green economy planning, governance and supervision are supported by mature institutions and funds

Drilled cuttings from wells are useful sources of information to describe the subsurface geological properties for formation evaluation. However, the process of cuttings analysis and description is known to be labor- and expert-intensive and lacks consistency. In our initial work, we proposed a workflow based on object-based image analysis (OBIA) to analyze digital cuttings images, which is driven by geology and enabled by machine learning and computer vision techniques. The key challenge in lithology estimation from digital cuttings images is the visual variety of rocks; it is known that rocks from different types of lithology might look very similar or almost identical on the standard optical image. In this paper, we revisit our initial workflow and propose lithology OBIA (LiOBIA), which focuses on the lithology estimation computational pipeline composed of two steps. In the first step, we use an advanced data-driven technique to extract color and texture features from cutting instance images. In the second step, we use k-nearest neighbor (k-NN) classification in the feature space (i.e., we retrieve similar cuttings from the reference data set and estimate the lithology based on the retrieved cuttings). A strength of this workflow is its flexibility. The workflow design allows for multiple quality control (QC) methods, extensions, and add-ons to the base workflow by incorporating any available data and information, whenever possible, such as integration of images under the ultraviolet (UV) light, lithology type filtering, and local cuttings data sets, to better estimate the lithology type. We evaluate the LiOBIA lithology estimation using our cuttings library data set, which includes five main lithology types. Our two-dimensional (2D) manifold analysis confirms that the visually similar cuttings are close to each other in the high-dimensional feature space. The classification result showed an accuracy of more than 90%. We also applied LiOBIA to two wells in Australia. The cuttings property logs, including lithology type, are generated and show a good trend match with independently acquired expert descriptions and downhole well logs. We demonstrate successful cases and discuss the limitations and potential improvements to our workflow.

Standard mud gas data are part of the basic mud-logging service and are mainly used for safety. Although the data are available for all wells, it is not used for real-time fluid typing due to poor prediction accuracy. We recently developed a new method based on a large in-house reservoir fluid database, which significantly improved the fluid typing accuracy from standard mud gas data. The new technology unlocks the large potential of utilizing standard mud gas data for thousands of wells. Standard mud gas data have limited gas components that can be detected confidently (usually from C1 to C3). In addition, they are raw data without recycling correction and extraction efficiency correction. Following the traditional geochemical analysis methods, some key parameters (C1/C, C1/C, Bernard ratio) have a universal threshold to distinguish gas and oil. The main reasons for poor fluid typing accuracy are due to (a) lacking C1 to C3 composition correction for wells with oil-based mud (OBM) and because (b) geochemical parameters based on C1 to C3 are field dependent. Based on the reservoir fluid database analysis, we divide the reservoir fluids from different fields into two categories. For Type I fields, there are large differences between C1 through C3 component ratios for oil and gas. When water-based mud (WBM) is used, C1 to C3 component ratios from standard mud gas can be utilized directly to identify oil and gas. When OBM is used, we developed a new method to achieve corrected standard mud gas composition for fluid typing using pseudo-extraction efficiency correction (EEC) based on equation of state (EOS). For Type II fields, there are severe overlapping of C1 to C3 component ratios for oil and gas. The overlapping is the main reason for the poor fluid typing accuracy. We recommend utilizing a heated degasser when drilling into Type II fields to provide additional data on C4 and C5 for accurate fluid typing. Johan Castberg is a Type I field, and we achieved excellent fluid typing results for 14 wells using WBM and OBM. There is no additional data acquisition cost for standard mud gas data, which are available for all wells. The new method makes accurate fluid typing possible for real-time well decisions like well placement, completion, and sidetrack. The innovation created significant business opportunities based on the standard mud gas, which has been regarded as not applicable data for accurate fluid typing for many decades.
History of development and prospects for further application of the geodynamic zoning method

Published: August 2024

The paper describes the background for the development of the geodynamic zoning method at VNIMI, which was the leading organization studying the problem of rock bursts, in the Soviet Union. This method is intended for zoning of deposits by the degree of geodynamic hazard and is aimed at assessing the stressed state of rock massif using the general-to-specific principle. The method involves identification of hierarchically ordered block structure of the rock massif; determination of the interaction dynamics between the blocks and assessment of the stressed state of the block massif, including the states upon commencement of the field development; development of recommendations for safe mining operations with account of the results obtained and possible changes in the stressed state of the rock mass under the impact of the mining operations. The method has also found its application in oil fields to identify promising locations for wells, in identifying geodynamically dangerous zones along the railroads and pipelines, residential and industrial areas. Theoretical provisions on the interaction of global geodynamic and local geomechanical processes during mining operations, concepts of the critically stressed state of the Earth's crust from the day-time surface down to a certain depth have been confirmed in practice and in research findings in different countries of the world. Conducting work on geodynamic zoning of coal and ore deposits that are prone to and hazardous in terms of rock bursts is stipulated by the current safety instructions. VNIMI continues to develop theoretical aspects of geodynamic zoning and performs practical work on geomechanical safety in the fields, which is shown using a case study of the Kamchatka region.
Multi-criteria assessment of rock bump hazard
Authors: Usoltseva O.M. , Volovik Ya.A.
Published: August 2024

A series of laboratory tests was carried out for 50 samples of different rock types (sandstones, siltstones, limestones, shaly silts) to evaluate the tendency of rocks to rock bumps. The tests were carried out using the Instron 8802 servohydraulic press in the uniaxial compression mode with the press clamp velocity travel of 0.1 mm/min. Five specimens were tested from each group of the same rock types. As the result, complete stress-and-strain diagrams including the post-peak deformation section were obtained. Evaluation of the rock bump hazard was performed using several criteria in order to compare their accuracy. Results of the calculations revealed that different criteria can give different estimates of the rock's tendency to bumps even for the same rock type. Based on analyzing the experimental data, it was concluded that the energy-based rock bump hazard indicator, defined as a difference value covering the entire rock fracture process, is the most reliable criterion.
