An analysis of the use of 3D game engine technology in visualising sustainability data

Purpose Responding to calls for accountants to engage with modern technologies and explore data visualisation within a three-dimensional (3D) environment, this study aims to explore whether social and environmental accounting (SEA) data visualisation is a promising use case for 3D game engine technology. Design/methodology/approach Drawing on visual perception and embodiment theories, this study uses photo-elicitation, a qualitative research method, to explore the usefulness of two-dimensional (2D) and 3D visualisations of sustainability information in a 3D virtual environment. This study provides three stimuli: numerical data, 2D visualisations and 3D visualisations, and asks open-ended questions regarding future applications. Twelve semi-structured interviews were conducted with academics, preparers and users of sustainability reports to obtain responses to these stimuli. Findings The key finding is that visualisation of SEA information may indeed be a strong use case for 3D game technology, but only for certain data and for certain audiences. Presenting information within a 3D virtual environment offered enhanced engagement and contextual understanding but reduced navigation speed and data clarity. Participants were enthusiastic about the potential of a museum-like experience, incorporating interactivity and community, but felt that the appropriate audience was more likely to be novices than experts. Practical implications This study suggests that deploying 3D game engine technology can be a powerful tool for presenting sustainability information but requires significant resources. The optimum audience is likely to be novices, and a key design principle is to ensure the virtual environment supports, rather than overwhelms, the information presented within that environment. Originality/value This study introduces a novel application of 3D visualisation technology within the SEA context, offering original insights into its potential to enhance user understanding and decision-making capabilities. This study highlights the technology’s value not as a replacement for traditional reporting but as a supplementary educational tool. The study also provides a novel setting for the photo-elicitation method, demonstrating this approach’s utility in a 3D environment.

Implementation of Car-Free Days in Support of Sustainable Development to Reduce Vehicle CO2 Emissions in Urban Areas

The transportation sector is one of the main contributors to global greenhouse gas emissions, accounting for 18.52% of total emissions, with this percentage reaching 40% in developed countries. This research aims to assess the effectiveness of Car-Free Day (CFD) implementation in reducing emissions in Cirebon, Indonesia, as a contribution to the 13th Sustainable Development Goal on climate action. The research method used a mixed approach, combining quantitative analysis of fuel consumption data with qualitative interviews to gain a comprehensive understanding of the impact of CFD. Referring to the Ministry of Environment and Forestry's National Greenhouse Gas Inventory guidelines, Book I: The results showed that while CFD reduced emissions by 13-26% in the designated lane due to traffic diversion, it also led to an 8-14% increase in emissions in the alternative lane. Therefore, the overall emission reduction effort was not optimal, as the emission reduction in one lane was masked by the emission increase in the other lane. The implication of this research is that a more holistic approach is needed to effectively reduce urban greenhouse gas emissions. The results of this research can serve as a basis for formulating more effective transportation policies, such as extending the duration and coverage of CFD, restricting vehicles on alternative routes, and improving public transportation systems that are more environmentally friendly.

Analysis of Surface Texture of Asphalt Mixture with Sand Circle Method

A road is usually defined as an infrastructure connecting a zone to other zones. As service and safety are essential for vehicle users, any conditions related to the pavement, including surface texture, are considered. The importance of this matter is that many researchers or practitioners are concerned with the quality of asphalt mixtures, whether structural or functional, which affect the safety and security of road users, mainly related to the texture of the pavement surface. This research aims to determine the texture depth (MTD, Mean Texture Depth). The research method used is the circle sand method, which is tested using the Sand Patch tool. The asphalt mixture type uses AC-WC with a composition of 39% coarse aggregate, 54.5% fine aggregate, and 6.5% filler. Optimum Asphalt Content of 6.28% and Density of 2.28 were obtained, and texture depth of 0.549 mm was more significant than 0.45 mm (Bina Marga 2010 revision 3). The conclusion is based on the design composition of the aggregate mix in the AC-WC asphalt mixture, which has a safe texture.

Associations of Clinical Characteristics With Sudden Cardiac Arrest in People With Type 2 Diabetes With and Without Cardiovascular Disease: A Longitudinal Case-Control Study Using Routine Primary Care Data

OBJECTIVE To assess longitudinal associations with sudden cardiac arrest (SCA) of clinical characteristics recorded in primary care in people with type 2 diabetes (T2D), both with and without cardiovascular disease (CVD). RESEARCH DESIGN AND METHODS We performed a case-control study, with SCA case subjects with T2D from the Amsterdam Resuscitation Studies (ARREST) registry of out-of-hospital resuscitation attempts in the Dutch Noord-Holland region (2010–2020) and up to five matched (age, sex, T2D, general practitioner [GP] practice) non-SCA control subjects. We collected relevant clinical measurements, medication use, and medical history from GPs’ electronic health care records. We analyzed the associations of clinical characteristics and medication use with SCA in the total sample and in subgroups with or without CVD using multivariable time-dependent Cox regression (hazard ratios, 95% confidence intervals). RESULTS We included 689 SCA case subjects and 3,230 non-SCA control subjects. In multivariable models, low fasting glucose (<4.5 mmol/mol: 1.91 [1.00–3.64]), antihypertensive (1.80 [1.39–2.33]), glucose lowering (oral only: 1.32 [1.06–1.63]; insulin only: 2.31 [1.71–3.12]; oral and insulin: 1.64 [1.21–2.22]), heart failure (1.91 [1.55–2.35]), and QTc-prolonging prokinetic (1.78 [1.27–2.50]), antibiotic (1.35 [1.05–1.73]), and antipsychotic (2.10 [1.42–3.09]) medication were associated with SCA in the total sample. In subgroup effect modification analyses, QTc-prolonging antibiotic (1.82 [1.26–2.63]) and antipsychotic (3.10 [2.09–4.59]) medication use were associated with SCA only in those without CVD. CONCLUSIONS In people with T2D, low fasting glucose and QTc-prolonging prokinetic, antibiotic, or antipsychotic medication use and a history of heart failure are associated with SCA risk. Subgroup analyses indicate antibiotic and antipsychotic medication use increases SCA risk specifically in those without CVD.

LEGALITY OF TRADITIONAL OIL MINING EXPLORATION IN RANTO PEUREULAK, EAST ACEH: AN ANALYSIS OF THE ISLAMIC ECONOMIC LAW PERSPECTIVE

This article aims to examine the legality of oil mining resulting from traditional mining exploitation by the Ranto Pereulak community, East Aceh. This research uses descriptive qualitative research methods and the approach used in this research is a sociological normative approach. This research was located in Ranto Peureulak District, which is one of the sub-districts in East Aceh Regency. The results of this research show that the East Aceh Government through Qanun Number 6 of 2009 provides space for the community to manage mining products, in this case oil, by obtaining an IUP issued by the East Aceh government and going through all the conditions therein. The IUP is granted by the Regent after obtaining principle permission or approval from the Governor through the relevant provincial and district level agencies. However, in practice, many people in Ranto Peureulak District, East Aceh Regency, in managing illegal wells traditionally do not follow the applicable SOPs or regulations. Then the oil drilling carried out can endanger the health of workers and the surrounding community. This can also have an impact on the environment, because it does not pay attention to health standards or Health Safety and Environment or abbreviated as (HSE), which is the main priority for mining. In terms of safety too, it often catches fire and causes casualties, both workers and residents. Because drilling oil and gas wells is a very complex process and at each step procedures, requirements and important decisions are required that must be considered and implemented very carefully.

Underwater Image Enhancement Methods Using Biovision and Type-II Fuzzy Set

Accurately extracting underwater images has never been more challenging, as the lack of clarity of detail due to issues such as scattering and light absorption is more noticeable than ever before. This research method addresses these problems while clarifying the limitations of existing methods and proposes a comprehensive approach to underwater image processing. Current methods tend to focus only on the effects of individual factors, such as color shifts, visibility, or contrast enhancement, and do not take into account biological vision applications. In contrast, the method proposed in this paper applies a color correction module that takes into account the effects of biological vision in LAB color space, and an enhanced Type-II Fuzzy set visibility enhancement module. This synchronized approach overcomes the limitations of the previous methods in that the contrast enhancement utilizes a curve transform and a multi-scale fusion strategy that preserves the essential image details. The framework not only adjusts the overall image features, but also finely handles the local details, resulting in a significant enhancement of both the overall quality and the local detail clarity of underwater images. The experimental results demonstrate that the application of the method of this study on two datasets gives results that are better than those of the top 10 existing algorithms. By explicitly addressing the limitations of existing methods, the method becomes an advantageous solution in underwater image processing, providing enhancements in image quality and task-specific applications in a concise and efficient manner.

Examining the Effects of Health Work Shortages and Deployment in Integrated Programme in Bihar, India: AnInstitutional Ethnography.

The integration of health programms in low-resource settings is a common approach aimed at providing quality and cost-effective healthcare services. However, programme integration can unintentionally impact service provision and disrupt the overall organisation of service delivery. In this paper, I examine the integrated programme for non-communicable diseases (NCDs) and explore the challenges related to the deployment of health workers. Specifically, I investigate the institutional processes that shape the work of health workers and the working conditions in district hospitals. To explore the social organisation of the implementation of the integrated NCD programme, I employed institutional ethnography as a research method. Data collection involved interviews, participant observation, and document reviews. Data analysis was conducted using social mapping, analytical writing, and textual analysis methods. The findings of the study suggest that due to staff shortages and a lack of doctors, health workers are continuously subjected to deployment and often required to undertake multiple tasks and responsibilities without any incentives or non-monetary benefits. Administrators perceive health workers in integrated programs as additional human resources available for use in district hospitals. However, the removal of health workers from integrated programs can have negative implications for service delivery and patients' health outcomes. Finding of the study suggests that it is recommended that administrators improve the staff recruitment process and promptly address the grievances of health workers to enhance healthcare delivery.

Workplace Diversity and Human Resource Performance Among Non-Teaching Staff of Selected Private Universities in Ogun State

The proliferation of privately owned institutions in Nigeria has led to a range of challenges, including the issue of workplace diversity. The observed phenomenon is a naturally occurring event that can have varying effects on worker performance, depending on the effectiveness of its management. Numerous research studies have demonstrated the significant impact of non-teaching personnel management on their performance in private university settings. This study investigates the influence of workplace diversity on the efficacy of human resource management, expanding on the existing theoretical framework. The study utilised a survey research method, specifically targeting private universities in Ogun State that have obtained approval from the National Universities Commission (NUC). A representative sample of respondents was selected. The data was collected using a meticulously designed questionnaire. Regression analysis of ordinary least squares (OLS) and Pearson product correlation were used to analyse workplace diversity and human resources performance among non-teaching staff in a selected private university in Nigeria. The regression analysis conducted in this study revealed a statistically significant association between workplace diversity, encompassing factors such as age, education, and gender, and employees' performance in Nigeria. Ethnic diversity has a detrimental effect on workplace diversity. The study indicates that it is important for organisational management to establish and implement policies that support diversity in the workforce, considering the varied backgrounds of all individuals involved.

A Tomato Sorting Automation Prototype Based on Color

Abstract—The process of sorting tomatoes can be done using visual methods by paying attention to color. The purpose of this research is to improve the process of sorting tomatoes based on color in distinguishing ripe tomatoes and immature tomatoes. Streamline the time of sorting tomato fruit in order to avoid losses due to spoilage. This research method is with a sample of tomato fruit taken RGB value through TCS 3200 color sensor according to the level of maturity. After the RGB value is obtained, it will be processed into the Arduino Uno to obtain maturity information through the rules that have been made and sorted using a servo motor. The results of this study indicate that a good condition for detecting tomato fruit is with a closer distance to the fruit with a dark background. This is because there is no excess light reflection so that the TCS sensor can take RGB values well and reduce the occurrence of misreading of ripeness information in the sorting process. Keywords— Tomato, Sensor TCS 3200, Arduino uno, Motor Servo.
