Leveraging Artificial Intelligence and Provenance Blockchain Framework to Mitigate Risks in Cloud Manufacturing in Industry 4.0

Cloud manufacturing is an evolving networked framework that enables multiple manufacturers to collaborate in providing a range of services, including design, development, production, and post-sales support. The framework operates on an integrated platform encompassing a range of Industry 4.0 technologies, such as Industrial Internet of Things (IIoT) devices, cloud computing, Internet communication, big data analytics, artificial intelligence, and blockchains. The connectivity of industrial equipment and robots to the Internet opens cloud manufacturing to the massive attack risk of cybersecurity and cyber crime threats caused by external and internal attackers. The impacts can be severe because the physical infrastructure of industries is at stake. One potential method to deter such attacks involves utilizing blockchain and artificial intelligence to track the provenance of IIoT devices. This research explores a practical approach to achieve this by gathering provenance data associated with operational constraints defined in smart contracts and identifying deviations from these constraints through predictive auditing using artificial intelligence. A software architecture comprising IIoT communications to machine learning for comparing the latest data with predictive auditing outcomes and logging appropriate risks was designed, developed, and tested. The state changes in the smart ledger of smart contracts were linked with the risks so that the blockchain peers can detect high deviations and take actions in a timely manner. The research defined the constraints related to physical boundaries and weightlifting limits allocated to three forklifts and showcased the mechanisms of detecting risks of breaking these constraints with the help of artificial intelligence. It also demonstrated state change rejections by blockchains at medium and high-risk levels. This study followed software development in Java 8 using JDK 8, CORDA blockchain framework, and Weka package for random forest machine learning. As a result of this, the model, along with its design and implementation, has the potential to enhance efficiency and productivity, foster greater trust and transparency in the manufacturing process, boost risk management, strengthen cybersecurity, and advance sustainability efforts.

Work Posture Analysis of Musculoskeletal Disorders (MSDs) Complaints in MSME Workers Balloon Bouquet

It is known that MSDs have become a health problem for workers in developing and developed countries over the past few years. Musculoskeletal disease is the second leading cause of disability in the world, with low back pain being the leading cause of disability. If referring to this explanation, the activities of MSME workers, balloon bouquets that can potentially cause musculoskeletal complaints, one of which is the activity of pumping balloons manually and stringing balloons with awkward postures and carrying out work with a sitting work posture which causes musculoskeletal problems, especially shoulder & waist problems because there is pressure on the spine. The type of research used by the author in this study is the qualitative method. Qualitative research researchers become the main instrument in collecting data that can be directly related to the instrument or object of research. Data collection method using Rapid Upper Limb Assessment (RULA) observation sheet and Nordic Body Map (NBM) checklist sheet as well as interview guidelines. Workers often experience complaints of aches or pains both while working, and after doing work on the right shoulder, left shoulder, back, upper arm, forearm, and waist. The posture of workers when making a bouquet of balloons either when pumping, forming, or assembling balloons on average has a high risk level for complaints of musculoskeletal disorders because workers carry out work with a sitting, bending, squatting, and half-sitting work attitude, there are repetitive movements.

Analysis of Work Posture in the Car Body Assembly Process Using the Rapid Entire Body Assessment Method

CV. Faisyal Putra Mandiri located at Kandangan Rejo Lebar street No.11 Surabaya City, is one of the manufacturing industry companies engaged in car body production. In their work activities there are still workers who do not apply ergonomic work postures while working. Unergonomic work positions can cause some parts of the body to not be in their normal position so that they are very vulnerable to musculoskeletal disorders. To overcome these problems, work posture improvement is carried out. Based on the results of the study, it was found that after simulating the use of tools in the metal cutting process, namely the Hydraulic Scissor Lift Table, it can reduce the risk of worker injury through a final REBA value of 7 with a moderate risk level to a final REBA value of 2 with a low risk level. Then in the welding process can reduce the risk of worker injury through the final REBA value of 9 with a high risk level to the final REBA value of 3 with a low risk level. In addition, it is recommended to use a chair as a tool, which is proven through work simulation to reduce the risk of injury. In metal cutting, the REBA value drops from 7 with a moderate risk level to 3 with a low risk level, and in welding, from 9 with a high risk level to 3 with a low risk level.

The Implementation of Roy's Safety-First Criterion in Stock Portfolio Selection

Statistical data shows that the Indonesian capital market has experienced significant growth. This growth is attributed to public awareness of the benefits of stock investments. However, with an increasing number of new investors entering the stock market, attention to investment risks deepens. Many investors prefer stocks that are easily predictable and have low risk, as higher volatility increases the level of uncertainty in obtaining returns. The relatively high risk level in investing requires investors to minimize risks, one of which is by diversifying funds into various investment assets, commonly known as optimal portfolio selection. An optimal portfolio can be formed using various methods and approaches. One method for portfolio selection is the application of the Safety First Criterion, a method dependent on downside risk, referring to risks that result in losses. This article conducts a simulation of the implementation of Roy's Safety First Criterion using stock data from the largest companies in eleven sectors over the past year. These sectors include basic materials, communication services, consumer cyclical, consumer defensive, energy, financial services, healthcare, real estate, technology, and utilities. Based on this analysis, out of the eleven stocks, six stocks meet Roy's criteria: LIN, GOOG, AMZN, BRK-B, LLY, and AAPL, with respective weights of LIN=10.84%, GOOG=12.61%, AMZN=24.67%, BRK-B=1.37%, LLY=34.17%, and AAPL=16.35%. Using Roy's Safety First Criterion for selected stocks from various sectors indicates that the resulting portfolio has a very low risk level, specifically 1%. This means that by using the portfolio obtained from the eleven stocks, investors can achieve minimal risk, making this portfolio secure for new investors.

PENGARUH STATUS KEPEGAWAIAN DAN TUNTUTAN PROFESIONALISME TERHADAP PENGUPAHAN TENAGA KESEHATAN

In many cases, the wages of health workers are still below the average regional/provincial minimum wage (UMR/UMP). This can have an impact on the motivation and fulfilment of health workers' performance standards. In addition, the high level of risk in the work environment requires physical and spiritual fitness which costs money. Based on these problems, this research tries to examine the influence of employment status and demands for professionalism on the wages of health workers for nursing health workers, who have the largest number in both government and private institutions. This type of research is normative-empirical, the data used is secondary data. Secondary data was obtained from library research sourced from Institute reports, official government statistics, regulations as primary, secondary, and tertiary legal sources. From the results of the study, information was obtained that employment status and professional responsibilities have a significant influence on wage standards in the form of salaries and allowances for ASN/PPPK which are regulated in applicable laws and regulations. Meanwhile, in private institutions, the amount is regulated in the non-employee agreement for state civil servants (private sector), given in accordance with the work agreement or collective work agreement.

Spatiotemporal changes in hurricane-force wind risk assessment in the Yucatan Peninsula, Mexico

Tropical cyclones are one of the most dangerous natural phenomena. These extreme events involve various hazards, such as strong winds, severe precipitation, storm surge, flooding, and landslides. In Mexico, tropical cyclones are the most frequent natural threats and have a high cost to affected populations. This research aimed to characterise the spatial and temporal changes in risk associated with hurricane winds on the Yucatan Peninsula. This effort included a comprehensive analysis of three integral risk components (hazard, vulnerability, and exposure) for three distinct time intervals (1950–2000, 1950–2010, and 1950–2020). This analytical process was executed utilising a fine-resolution hexagonal grid. Hazard was estimated by calculating the probabilities of occurrence of winds related to various hurricane categories after estimating wind fields from the International Best Track Archive for Climate Stewardship (IBTrACS) data with a parametric model. Vulnerability was approximated by constructing indicators with sociodemographic data from the National Population and Housing Census issued by Mexico’s National Institute of Statistics and Geography. With these indicators, a factor analysis was performed, and a weighted index was constructed. Finally, exposure was estimated from population density. Each of these indices was aggregated at the hexagonal level, allowing the calculation of the risk associated with hurricane-force wind. The results showed high-risk levels associated with high-hazard levels, e.g. in coastal areas such as the Riviera Maya. Similarly, high-risk levels are related to high marginalisation, i.e. vulnerability, in the northeastern zone of the Yucatan Peninsula. The increased frequency of tropical cyclones combined with high population densities has recently led to higher risk levels in this region of Mexico.

Development of Experimental Models on Floating Breakwaters

Indonesia is the largest archipelagic country in the world with a potential area consisting of 17,480 islands with a sea stretch of 5.8 million km2 and has the fourth longest coastline in the world at 95,181 km, has a very high level of risk of abrasion hazards, especially considering that more than 60% of Indonesians live in coastal areas. The main purpose of a floating breakwater is to protect an area against unwanted wave heights. One of the most important boundary requirements in port design is allowable downtime. This is a period of time when the port cannot fulfill its function so as to prevent the occurrence of unwanted things from the movement of ships. Downtime occurs when a certain wave height is exceeded, causing unwanted ship movements. This implies that the wave transmitted by the floating breakwater to the port determines the downtime. Of the 7 (seven) types that exist, the box type is taken for research because the box type is more effective and efficient in dampening waves. Then the type of box that is used as a test model is carried out with 2 (two) conditions. The test model to be studied is a floating pontoon with a mooring line and a floating pontoon tethered to a pile.

Analisis Risiko Bahaya Kesehatan dan Keselamatan kerja (K3) Pengelasan dengan Metode Fishbone Diagram dan Job Safety Analisis (JSA)

Occupational Safety and Health (K3) are activities that ensure the creation of safe working conditions, avoiding physical and mental disorders. The aim of this research is to determine the risk of severity of welding workers who do not use Personal Protective Equipment (PPE). This research uses 2 methods, the fishbone diagram method and job safety analysis. The survey technique was carried out by taking a sample of 15 welding worker respondents in the company. The results of this research are that welding workers experience a very high level of risk to Occupational Health and Safety due to the lack of Personal Protective Equipment (PPE) used. So companies must provide, comply with and prioritize (K3) welding. The company must also facilitate and require all workers to use safety equipment such as welding Personal Protective Equipment (PPE) that meets the Indonesian National Standard (SNI).

Air pollutants, genetic susceptibility, and abdominal aortic aneurysm risk: a prospective study.

Air pollutants are important contributors to cardiovascular diseases, but associations between long-term exposure to air pollutants and the risk of abdominal aortic aneurysm (AAA) are still unknown. This study was conducted using a sample of 449 463 participants from the UK Biobank. Hazard ratios and 95% confidence intervals for the risk of AAA incidence associated with long-term exposure to air pollutants were estimated using the Cox proportional hazards model with time-varying exposure measurements. Additionally, the cumulative incidence of AAA was calculated by using the Fine and Grey sub-distribution hazards regression model. Furthermore, this study investigated the combined effects and interactions between air pollutants exposure and genetic predisposition in relation to the risk of AAA onset. Long-term exposure to particulate matter with an aerodynamic diameter <2.5 µm [PM2.5, 1.21 (1.16, 1.27)], particulate matter with an aerodynamic diameter <10 µm [PM10, 1.21 (1.16, 1.27)], nitrogen dioxide [NO2, 1.16 (1.11, 1.22)], and nitrogen oxides [NOx, 1.10 (1.05, 1.15)] was found to be associated with an elevated risk of AAA onset. The detrimental effects of air pollutants persisted even in participants with low-level exposure. For the joint associations, participants with both high levels of air pollutants exposure and high genetic risk had a higher risk of developing AAA compared with those with low concentrations of pollutants exposure and low genetic risk. The respective risk estimates for AAA incidence were 3.18 (2.46, 4.12) for PM2.5, 3.09 (2.39, 4.00) for PM10, 2.41 (1.86, 3.13) for NO2, and 2.01 (1.55, 2.61) for NOx. In this study, long-term air pollutants exposure was associated with an increased risk of AAA incidence.

Climate Risks in the Commercial Mortgage Portfolios of Life Insurers: A Focus on Sea Level Rise and Flood Risks

In this paper, we explore the climate risk exposure of U.S. life insurers' commercial mortgage loan portfolios, focusing on sea level rise (SLR) and flood risks. While vast literature and industry reports document the potential impact of climate change on the insurance industry, most focus on the property insurance market. Life insurers hold a significant number of commercial mortgages, representing approximately 15% of their assets by the end of 2021. These investments are susceptible to both physical and transitional risks of climate change and are much less researched or understood. From 2012 to 2019, we find that the size of newly issued commercial mortgages by life insurers in the U.S. grew from $37 billion to $56 billion (by 51%). We find heterogeneity across life insurers in terms of the average loan size, the loan origination frequency, as well as loan locations. In terms of locations, life insurers tend to originate loans in metropolitan areas, many of which are on the coast. Some life insurers focus on specific geographical areas that happen to be exposed to high levels of SLR or flood risks (e.g., Florida), while some diversify across metropolitan areas (coastal or noncoastal) in the U.S. Our findings have important policy implications for regulators and researchers.

Particle size, carbon composition and sources of indoor dust in Nanchang, China

Indoor dust is an enriched environmental media for lots of chemical pollutants, while indoor pollutants pose high exposure level and health risks to humans. In this work, indoor dust samples from four types of indoor environments (residence near steel plant, residence near road, student dormitory and rural kitchen) in Nanchang city were collected and their particle sizes and carbon components were analyzed. The sources of carbon components were traced based on the distribution of carbon components and the correlation between the components. The particle size distribution mainly presents a bimodal mode (0.1–3 and 10–40 μm size intervals, accounting for 8.9% and 7.4%). The average OC and EC in the as-collected indoor dust samples were 34.1 and 52.7 mg/g for residences around the steel plant, 43.9 and 41.4 mg/g for residences adjacent to the road, 119.3 and 66.4 mg/g for students' dormitories, 73.5 and 49.8 mg/g for rural kitchens, respectively. A strong correlation between OC and Char was observed, indicating strong homology between the sources of the two components. In addition, the correlation between two of EC1, OC2, and OC3 (OC2 and OC3 are fractions of OC and EC1 is a fraction of EC) were significant, indicating a large contribution of motor vehicle exhaust to indoor dust. The average ratios of OC/EC and Char/Soot suggest the contribution of automobile exhaust, indoor smoking and biomass combustion to indoor dust. The results of this work provide a scientific, convenient, and reliable approach to explore the source of particulate matter indoors based on the distribution of carbon components.

The conclusion of this research is that the potential dangers that exist in PD Sumber Putri Rejeki are injured hands, injured feet, shoulder injuries, cut limbs, respiratory problems and vision problems. The average potential hazard value with the highest level of risk is cutting work with an RPN value of 74, while the description of the potential hazard for all jobs is visual impairment due to material residue in contact with the eyes with an RPN value of 108.

Tissue accumulation of microplastics and potential health risks in human

Microplastics have become ubiquitous throughout the environment. Humans constantly ingest and inhale microplastics, increasing concerns about the health risks of microplastic exposure. However, limited data impedes a full understanding of the internal exposure to microplastics. Herein, to evaluate microplastic exposure via the respiratory and digestive systems, we used laser direct infrared spectroscopy to identify microplastics >20 μm in size in different human tissues. Consequently, 20–100 μm microplastics were concentrated in all tissues, with polyvinyl chloride (PVC) being the dominant polymer. The highest abundance of microplastics was detected in lung tissue with an average of 14.19 ± 14.57 particles/g, followed by that in the small intestine, large intestine, and tonsil (9.45 ± 13.13, 7.91 ± 7.00, and 6.03 ± 7.37 particles/g, respectively). The abundance of microplastics was also significantly greater in females than in males (p < 0.05). Despite significant diversity, our estimation showed that the lungs accumulated the highest amounts of microplastic. Moreover, PVC particles may cause potential health risks because of their high polymer hazard index and maximal risk level. This study provides evidence regarding the occurrence of microplastics in humans and empirical data to support assessments of the health risks posed by microplastics.

Contamination Characteristics and Source Apportionment of Soil Heavy Metals in an Abandoned Pyrite Mining Area of Tongling City, China

To investigate the impact of pyrite mining on the heavy metal pollution in the surrounding soil in Tongling City, 50 surface soil and sediment samples were collected from mining fields, farmland, forests, villages, and the river. The contents of Zn, Cr, Cu, Pb, Ni, Cd, and As in soils and sediments were analyzed. Then, the spatial distribution characteristics of heavy metals in soil were analyzed, and the degree of heavy metal pollution and potential ecological risk level were assessed. Finally, the sources of soil heavy metal pollution were identified. In general, the soil in the study area was weakly acidic (average pH=6.32), and the contents of other heavy metals except Ni exceeded the background values of the soil in Tongling City. Moreover, Ni and Cd were enriched in the river sediments. According to the Nemerow pollution index, Pb and As reached heavy pollution levels, Cu and Cd reached moderate pollution levels, and other elements belonged to light or non-pollution levels. The comprehensive pollution index of different land types was ranked in the order of mining field &gt; river &gt; forest &gt; farmland &gt; village. Mining fields and the river were heavily polluted, forest land was moderately polluted, and farmland and villages were mainly mildly polluted. Pb, As, and Cd belonged to the medium ecological risk category. The contribution rates of the potential ecological risk index were 33.27%, 27.39%, and 20.22%, which were much higher than the other four elements. The ranking results of the potential ecological risk index of different land types was the same as that of the comprehensive pollution index. Mining fields and the river were at a high-risk level, forest land reached moderate risk, and the rest were at a slight risk level. The consistent results of correlation analysis, principal component analysis (PCA), and positive definite matrix factor analysis (PMF) indicated that Zn, Cu, Pb, Cd, and As were mainly derived from pyrite mining activities, Cr mainly came from the parent material and agricultural production, and Ni was mainly affected by soil-forming parent material and pyrite mining activities.

"I Haven't Told Anyone but You": Experiences and Biopsychosocial Support Needs of People With Type 2 Diabetes and Binge Eating.

Up to 25% of people with type 2 diabetes (T2D) may binge eat which is almost 10 times as many as in the general population. Binge eating is associated with depression, anxiety, and social isolation. Moreover, binge eating may increase the risk of obesity and high blood glucose levels, both of which can accelerate the onset of complications to diabetes and death in people with T2D. Still, little is known about the experiences, needs, and preferences of people with T2D and binge eating that can inform and develop current and future treatment efforts. The aim of the study was therefore to gain in-depth insights into the experiences and biopsychosocial support needs of women and men with T2D and binge eating. Twenty semi-structured individual interviews (65% with females) were conducted and analyzed according to the methodology of Interpretive Description. Four themes were identified: (a) T2D and binge eating: Feeling trapped in a vicious circle; (b) Unwanted outcasts: Responding to continuous criticism; (c) Biomedical relief: Blaming and adjusting the body; and, (d) Silent struggles: Wanting to cease the secrecy. Pertinent to all themes were the guilt, shame, and worries about developing complications that the participants experienced when binge eating despite having T2D. Although binge eating triggered emotional distress, binge eating was at the same time a way of coping with such distress. Implications for treatment and future research are discussed, including the need to systematically assess and address binge eating in routine T2D care.

Factors Contributing to Work Fatigue Among Construction Workers

The construction sector is one of the work sectors with a high level of risk of danger. The activities carried out by construction workers can cause errors and work accidents which are influenced by fatigue. This research aims to understand the factors related to work fatigue in construction workers in the Drinking Water Management System Project. The research method used was an explanatory study with a cross-sectional design, with a total sample of 30 people taken using a total sampling technique. Primary data was collected by distributing standard questionnaires, namely the Subjective Self Rating Test and Depression Anxiety Stress Scales (DASS) 42. Data were analyzed univariately using the frequency distribution test, bivariate analysis using the Chi-Square test, and data were visualized using the Tableau Public 2022 application. From the results, the research found that age (p=0.104), education (p=0.419), and length of work (p=0.063) were not related to work fatigue, while nutritional status (p=0.042) and work stress (p=0.028) were related to the incidence of work fatigue. The research conclusion is that nutritional status and work stress are related to work fatigue in construction workers in the Drinking Water Management System Project. Suggestions to project organizers, it is necessary to carry out effective stress management and coping for workers to reduce work fatigue and maintain workers' nutritional status by providing food according to workers' calorie needs.
