The occupational health risk associated with the production of prefabricated concrete components is often overlooked. This paper will use a damage assessment and cyclic mitigation (DACM) model to provide individualized exposure risk assessment and corresponding mitigation management measures for workers who are being exposed.

The DACM model is proposed based on the concept of life cycle assessment (LCA). The model uses Monte-Carlo simulation for uncertainty risk assessment, followed by quantitative damage assessment using disability-adjusted life year (DALY). Lastly, sensitivity analysis is used to identify the parameters with the greatest impact on health risks.

The results show that the dust concentration is centered around the mean, and the fitting results are close to normal distribution, so the mean value can be used to carry out the calculation of risk. However, calculations using the DACM model revealed that there are still some work areas at risk. DALY damage is most severe in concrete production area. Meanwhile, the inhalation rate (IR), exposure duration (ED), exposure frequency (EF) and average exposure time (AT) showed greater impacts based on the sensitivity analysis.

Based on the comparison, the DACM model can determine that the potential occupational health risk of prefabricated concrete component (PC) factory and the risk is less than that of on-site construction. It synthesizes field research and simulation to form the entire assessment process into a case-base system with the depth of the cycle, which allows the model to be continuously adjusted to reduce the occupational health damage caused by production pollution exposure.

This study aims to better understand the morphological characteristics of single particle and the health risk characteristics of heavy metals in PM_2.5 in different functional areas of Handan City.

High resolution transmission electron microscopy was used to observe the aerosol samples collected from different functional areas of Handan City. The morphology and size distribution of the particles collected on hazy and clear days were compared. The health risk evaluation model was applied to evaluate the hazardous effects of particles on human health in different functional areas on hazy days.

The results show that the particulate matter in different functional areas is dominated by spherical particles in different weather conditions. In particular, the proportion of spherical particles exceeds 70% on the haze day, and the percentage of soot aggregates increases significantly on the clear day. The percentage of each type of particle in the teaching and living areas varied less under different weather conditions. Except for the industrial area, the size distribution of each type of particle in haze samples is larger than that on the clear day. Spherical particles contribute more to the small particle size segment. Soot aggregate and other shaped particles contribute more to the large size segment. The mass concentrations of hazardous elements (HEs) in PM_2.5 in different functional areas on consecutive haze pollution days were illustrated as industrial area > traffic area > living area > teaching area. Compared with the other functional areas, the teaching area had the lowest noncarcinogenic risk of HEs. The lifetime carcinogenic risk values of Cr and As elements in each functional area have exceeded residents’ threshold levels and are at high risk of carcinogenicity. Among the four functional areas, the industrial area has the highest carcinogenic and noncarcinogenic risks. But the effects of HEs on human health in the other functional areas should also be taken seriously and continuously controlled.

The significance of the study is to further understand the morphological characteristics of single particles and the health risks of heavy metals in different functional areas of Handan City. the authors hope to provide a reference for other coal-burning industrial cities to develop plans to improve air quality and human respiratory health.

The study aims to apply catastrophe theory to the analysis of accidental dwelling fire injuries in terms of age band, gender and contributory factors in order to inform fire prevention activities.

The study employed a case study in a UK Fire and Rescue service concerning analysis of the circumstances of accidental dwelling fire injuries, and the characteristics and behaviours associated with utilising frequency analysis, percentages, ratios and catastrophe theory modelling.

Overall, males were more likely to be injured in an accidental dwelling fire compared to females by a ratio of 1.68 to 1, and those in the age band 50–64 appeared to be at maximum risk. A total of 15.4% of the accidental dwelling fire injuries involved consumption of alcohol or drugs, and 5.9% involved falling asleep.

The circumstances of accidental dwelling fire injury can be analysed to identify patterns concerning when a catastrophic change relating to ordinary use of domestic objects results in an accidental dwelling fire injury.

A catastrophe theory view can aid the understanding of how ordinary use of domestic objects results in an accidental dwelling fire injury.

Since fire injuries have both a social and economic cost, understanding how such fire injuries occur can aid fire prevention through appropriately targeted fire prevention activities.

The study made use of a catastrophe theory view to analyse the circumstances under which accidental dwelling fire injuries occurred using fire injury data from a UK fire and rescue service.

The purpose of this study was to explore the potential benefits of Coriandrum sativum (C. sativum) on anxiety, depression, sleep quality and memory among students.

This randomized controlled trial involved university students aged 18–25 years, who had no known allergies to C. sativum or were using psychotropic medication. After giving informed consent, participants were randomly assigned using a computer-generated random sequence to either 500 mg C. sativum seeds or a placebo. Primary outcomes measured changes in memory (prospective and retrospective memory questionnaire [PRMQ]), anxiety and depression (Hospital Anxiety and Depression Scale), while secondary outcomes assessed sleep quality (Pittsburgh sleep quality inventory [PSQI]).

A sample of 86 students with a mean age of 20.05 ± 1.6 years was selected for the study. Initial assessments ensured no significant differences in demographic or study variables between the control and intervention groups. Statistical analysis revealed significant improvements in memory (PRMQ: p = 0.006), anxiety (Hospital Anxiety Scale: p = 0.04) and depression (Hospital Depression Scale: p = 0.002), as well as in sleep quality (PSQI: p = 0.03) in the group receiving C. sativum compared to the control group.

This research offers initial insights into the potential benefits of C. sativum intake, specifically its role in enhancing memory performance and mitigating anxiety among student populations. The results present a compelling case for further research in this domain to solidify these preliminary conclusions.

Despite the contributions of both the oil and gas and construction industries to the gross domestic product (GDP) of the country, both industries are still marred by incessant accidents. Therefore, the aim of this study is to compare the health and safety practises of the construction and oil and gas industries in Nigeria in order to suggest the best approach to health and safety practices.

A survey questionnaire was developed and administered to professionals working in the construction and oil and gas industries. Data were analysed using the relative importance index (RII). An independent sample t-test was also conducted to determine whether there was a significant difference in the construction and oil and gas industries.

The study revealed that the rate at which health and safety are practised in the oil and gas industry is comparatively high compared to how they are practised in the construction industry. Proper site layout and planning, provision of a safe working environment, proper health and safety risk assessment were more predominantly practised in the oil and gas industry, while proper site layout and planning, disallowing unauthorised entry into site and the provision of a safe working environment were predominantly practised in the construction industry.

This study is the first to compare the health and safety practises of the construction and oil and gas industries in Nigeria. This study was significant because it would provide insight into construction and oil and gas managers, as well as other decision-makers in both industries, on how to improve health and safety practices.

Acute and chronic obstructive pulmonary disease (COPD) is a common and progressive lung disease that makes breathing difficult over time and can even lead to death. Despite this, there is no definitive treatment for it yet. This study aims to evaluate the studies on single and combined herbal interventions affecting COPD.

In this study, all articles published in English up to 2020 were extracted from the Web of Science (WoS) database and collected using Boolean tools based on keywords, titles and abstracts. Finally, the data required for bibliographic analysis, such as the author(s), publication year, academic journal, institution, country of origin, institution, financial institution and keywords were extracted from the database.

A total of 573 articles were analyzed. The number of papers in the lung disease field showed an upward trend from 1984 to 2021, and there was a surge in paper publications in 2013. China, Korea and Brazil published the highest number of studies on COPD, and Chinese medical universities published the most papers. Three journals that received the highest scores in this study were the Journal of Ethnopharmacology, International Immunopharmacology and Plos One. In the cloud map, expression, activation and expression were the most frequently researched subjects. In the plus and author keywords, acute lung injury was the most commonly used word. Inflammation, expression of various genes, nitric oxide-dependent pathways, NFkappa B, TNFalpha and lipopolysaccharide-dependent pathways were the mechanisms underlying COPD. Scientometric analysis of COPD provides a vision for future research and policymaking.

This study aimed to evaluate the studies on single and combined herbal interventions affecting COPD.

Nanotechnology (NT) advancements in personal protective textiles (PPT) or personal protective equipment (PPE) have alleviated spread and transmission of this highly contagious viral disease, and enabled enhancement of PPE, thereby fortifying antiviral behavior.

Review of a series of state of the art research papers on the subject matter.

This paper expounds on novel nanotechnological advancements in polymeric textile composites, emerging applications and fight against COVID-19 pandemic.

As a panacea to “public droplet prevention,” textiles have proven to be potentially effective as environmental droplet barriers (EDBs).

PPT in form of healthcare materials including surgical face masks (SFMs), gloves, goggles, respirators, gowns, uniforms, scrub-suits and other apparels play critical role in hindering the spreading of COVID-19 and other “oral-respiratory droplet contamination” both within and outside hospitals.

When used as double-layers, textiles display effectiveness as SFMs or surgical-fabrics, which reduces droplet transmission to <10 cm, within circumference of ∼0.3%.

NT advancements in textiles through nanoparticles, and sensor integration within textile materials have enhanced versatile sensory capabilities, robotics, flame retardancy, self-cleaning, electrical conductivity, flexibility and comfort, thereby availing it for health, medical, sporting, advanced engineering, pharmaceuticals, aerospace, military, automobile, food and agricultural applications, and more. Therefore, this paper expounds on recently emerging trends in nanotechnological influence in textiles for engineering and fight against COVID-19 pandemic.

To address safety risks, worker well-being concerns and productivity losses in construction due to substance misuse, this study aims to explore awareness and usage levels of various substances among Nigerian construction professionals. The findings aim to inform targeted interventions and policy development to tackle these industry-specific challenges.

A comprehensive literature review identified several substances and intoxicants commonly used in construction, which informed the development of a well-structured questionnaire. This questionnaire was distributed to both construction professionals and nonprofessionals. The Shapiro-Wilk test assessed the normality of awareness and utilization scores for each substance, while the Kruskal-Wallis H-test explored significant differences in awareness and usage scores among different respondent groups.

Despite reporting low awareness of substances commonly used in construction, a significant proportion (over 60%) of respondents admitted to using several of these substances in their construction activities. This highlights a concerning disconnect, with more than half (62.5%) exceeding a predefined threshold (3.5) for significant substance use. Ten out of the 16 substances surveyed fell into this category, indicating a widespread issue within the industry.

The findings of this study highlight the need for increased education and awareness programs about the dangers of substance misuse in the construction industry. Construction companies should implement regular training sessions and workshops to educate workers on the risks associated with substance use. Additionally, there should be stricter enforcement of substance use policies and routine substance testing to deter misuse. These measures can enhance safety, improve worker well-being and boost overall productivity in the construction industry.

The insights from this study can inform the development of international policies and best practices for substance use prevention and worker well-being in the construction industry. Sharing these findings with international organizations, policymakers and industry stakeholders can help create broader guidelines and frameworks adaptable for implementation in various countries.

The ceramic tile chain can generate several environmental impacts, from raw material extraction to the production process, commercialization, consumption, maintenance and disposal. One of the open issues remaining in the literature on socially responsible supply chains, also known as responsible supply chains, is understanding how corporate social responsibility (CSR) practices are being implemented in ceramic tile companies in Brazil.

The method adopted is a multiple-case study. The authors conducted face-to-face interviews with six ceramic producers and a trade association. The authors also conducted eight interviews with specialists in the ceramic sector. They are two university professors, two class association representatives, one professional from a technological institute, two representatives of the inspection body and one supplier.

Companies perform on a compliance basis, manifesting a less proactive position when the subject is CSR. In addition, the CSR practices established by the companies are preferably aimed at reducing costs and risks and increasing reputation. Practices in terms of eco-design are linked to lowering costs and growing reputation, as seen from the reduction in the use of inputs and improvements in packaging to minimize costs. These practices improve the company’s reputation from the consumers' perspective. Environmental aspects are dominant due to the legislation.

This paper contributes theoretically since it identifies, from the companies' perspective, the CSR practices related to risk, cost reduction and reputation increase. There are also opportunities to be explored for facilitating their efforts towards a sustainable business model, especially considering the social dimension. From a managerial perspective, this paper provides some input for implementing CSR actions, mainly regarding their implications for society and local communities.

La cadena de revestimiento cerámico puede generar diversos impactos ambientales, desde la extracción de la materia prima hasta el proceso de producción, comercialización, consumo, mantenimiento y disposición. Una de las cuestiones abiertas que quedan en la literatura sobre cadenas de suministro socialmente responsables, también conocidas como cadenas de suministro responsables, es comprender cómo se están implementando prácticas de responsabilidad social empresarial en las empresas de revestimientos cerámicos en Brasil.

El método utilizado en el estudio es un estudio de casos múltiples. Realizamos entrevistas cara a cara con 6 productores de cerámica y una asociación comercial. También recibimos información de 8 especialistas representantes de organizaciones relacionadas con el sector cerámico; 2 profesores universitarios; 2 representantes de asociaciones de clase; 1 profesional de instituto tecnológico; 2 representantes del organismo de control; y 1 proveedor de esmaltes.

Las empresas actúan sobre la base del cumplimiento, manifestando una posición menos proactiva cuando el tema es la RSE. Además, las prácticas de RSC establecidas por las empresas están preferentemente encaminadas a la reducción de costes y riesgos y al aumento de la reputación. Las prácticas en materia de ecodiseño están esencialmente ligadas a la reducción de costos y al aumento de la reputación, a partir de la reducción en el uso de insumos y mejoras en los empaques para minimizar costos. Estas prácticas mejoran la reputación de la empresa desde la perspectiva de los consumidores. Los aspectos ambientales son dominantes debido a la legislación.

Este trabajo aporta teóricamente ya que identifica, desde la perspectiva de las empresas, las prácticas de RSE relacionadas con el riesgo, la reducción de costos y el aumento de la reputación. También hay oportunidades por explorar para facilitar sus esfuerzos hacia un modelo de negocio sostenible, especialmente teniendo en cuenta la dimensión social. Desde la perspectiva gerencial, este documento proporciona algunos insumos para la toma de decisiones sobre la implementación de acciones de RSE, principalmente en lo que respecta a las implicaciones para la sociedad y las comunidades locales.

Invented in late 1890s, asbestos cement sheeting rose to prominence during the post-Second World War period as a building material for low-cost housing by state housing commissions and low-income families (“fibro homes”). The adverse health effects of asbestos fibres in the building industry and home renovation activities are well documented. Fibro homes of the 1950s and 1960s are increasingly coming under the gaze of heritage studies, which brings to the fore the question of how to deal with the asbestos cement sheeting most are clad with.

This paper provides the first systematic review to assess the literature (126 papers were identified in Google Scholar and scanned for content) on the conservation management of asbestos cement sheeting in heritage properties.

Overall, engagement with the conservation management of asbestos cement sheeting in heritage properties was low, with only two sources dealing with asbestos cement sheeting in any level of detail. The studies note that if asbestos cement sheeting is in good condition, it should be left alone. Numerous conservation and repair options do exist, in particular the application of (coloured) sealants that extend the life of asbestos cement sheets and asbestos cement roofing.

This paper represents the first systematic review to assess conservation management options for asbestos cement sheeting in heritage properties.
