Images of Chest Computer Tomography (CT) and Radiation (X-ray) Demonstrating Clinical Manifestations of COVID-19: Review Article
Authors: Oglat Ammar A.
Published: July 2024

Apart from reverse-transcription polymerase chain reaction (RT-PCR) testing, chest radiographs (CXR) and computed tomography (CT) scans were employed as crucial diagnostic methods for detecting the 2019 new coronavirus disease (COVID-19). Our objective is to examine three notable COVID-19 instances from patients across the globe, along with their CXR and CT data. The evaluation of the imaging characteristics of the reported instances was the primary objective of a methodical examination of the literature. We located more than several articles that had been published between 2020 and 2023. After the papers were examined, three major cases were chosen, including a COVID-19 assessment of imaging features (chest X-ray and CT scan). Corona viral diseases (COVID-19) pose a significant risk to healthcare facilities, especially when the patient has additional medical issues. It is challenging to understand the various chest radiography results because of the use of specialized and ambiguous terminology such as “airspace disease”, “pneumonia”, “infiltrates”, “patchy opacities”, and “hazy opacities”. The current investigation considered peer-reviewed case reports with Images features. Study designs, including reporting cases, were considered for imaging feature analysis.

Published: July 2024

Populations are exposed daily to numerous environmental pollutants, particularly through food. To address environmental issues, many agricultural production methods have been developed, including organic farming. To date, there is no exhaustive inventory of the contamination of organic foods as there is for conventional foods. The main objective of this work was to construct a growing and updatable database on chemical substances and their levels in organic foods consumed in Europe. To this end, a literature search was conducted, resulting in a total of 1207 concentration values from 823 food–substances pairs involving 166 food matrices and 209 chemical substances, among which 95% were not authorized in organic farming and 80% were pesticides. The most encountered substance groups are “inorganic contaminants” and “organophosphate”, and the most studied food groups are “fruit used as fruit” and “Cereals and cereal primary derivatives”. Further studies are needed to continue updating the database with robust and comprehensive data on organic food contamination. This database could be used to study the health risks associated with these contaminants.
On Superposition Lattice Codes for the K-User Gaussian Interference Channel
Authors: Estela María Constanza , Valencia-Cordero Claudio
Published: July 2024

In this study, we work with lattice Gaussian coding for a K-user Gaussian interference channel. Following the procedure of Etkin et al., in which the capacity is found to be within 1 bit/s/Hz of the capacity of a two-user Gaussian interference channel for each type of interference using random codes, we work with lattices to take advantage of their structure and potential for interference alignment. We mimic random codes using a Gaussian distribution over the lattice. Imposing constraints on the flatness factor of the lattices, the common and private message powers, and the channel coefficients, we find the conditions to obtain the same constant gap to the optimal rate for the two-user weak Gaussian interference channel and the generalized degrees of freedom as those obtained with random codes, as found by Etkin et al. Finally, we show how it is possible to extend these results to a K-user weak Gaussian interference channel using lattice alignment.

Published: July 2024

Burn care quality indicators are used to monitor and improve quality of care and for benchmark purposes. The perspectives of burn survivors, however, are not included in current sets of quality indicators while patient-centred care gains importance. The aim of this study was to explore burn survivors’ perspectives on quality aspects of burn care, which was used to translate their perspectives into patient-centred quality of care indicators. Qualitative descriptive research was conducted in a patient panel group. First, thematic analysis was applied to the focus groups to identify overarching themes. Second, patient-centred quality indicators, informed by burn survivors’ valued aspects of care, were defined. Ten burn survivors with an average age of 54 years (SD = 11; range 38–72 years) and mean TBSA burned of 14% (SD = 11%; range 5–35%) participated in two focus groups. Four overarching themes were identified, pointing to the importance of (1) information tailored to the different phases of recovery, (2) significant others’ wellbeing and involvement, (3) a therapeutic relationship and low-threshold access to healthcare professionals and (4) to participate in decision-making. Eighteen patient-centred process quality of care indicators within nine aspects of care were formulated. The overarching themes are reflected in patient-centred quality indicators, which present a broadened and complementary view of existing clinical quality indicators for burn care. Evaluating these patient-centred quality indicators may increase quality of care and refine patient-centred care.

Authors: Wong Wei Lun , Carlsson Kristina , Lindblad Marie , Sjökvist Olivia , Huss Fredrik
Published: July 2024

Burn mass casualty event occurrences are rare but will place significant burdens on any burn unit or healthcare system. Effective disaster preparedness plays a significant role in mitigating the aftermath of a burn mass casualty. The aim of this study was to assess the resource requirements during the initial two weeks of a burn mass casualty event. Eight patients in a burn mass casualty event were simulated using the Emergo Train System®. These simulated patients were matched with real historical patients treated in our burn centre, and their resource requirements were analysed. An average of eight staff is required to care for a patient per day along with almost 75 h of operating time (excluding anaesthesia and turnover time). A substantial quantity of consumables was used in the first two weeks. This study has demonstrated the substantial material consumption and staff requirements in the first two weeks of management in a burn mass casualty event. Such findings will offer valuable insight for disaster preparedness planning and resource management strategies.
The Impact of ChatGPT on English for Academic Purposes (EAP) Students’ Language Learning Experience: A Self-Determination Theory Perspective
Authors: Du Jinming , Alm Antonie
Published: July 2024

This qualitative study explores the perceptions of English language students regarding the use of the generative AI tool, ChatGPT, as a supportive tool for English for Academic Purposes (EAP) students in a New Zealand university context. Using self-determination theory (SDT) as an explanatory framework, this study explores how ChatGPT impacts students’ basic psychological needs for autonomy, competence, and relatedness in their language-learning experience. Semi-structured interviews are conducted with 24 postgraduate EAP students and the data are analysed using thematic analysis. The findings suggest that ChatGPT has the potential to support students’ needs for autonomy and competence by providing flexibility, personalised feedback and a safe space for practice. However, the impact on relatedness needs is mixed, with some students experiencing a sense of companionship and others expressing concerns about reduced human interaction. While students acknowledge the benefits of ChatGPT, they also emphasise the importance of human-teacher interactivity and empathy. The findings provide theoretical insights and practical recommendations for educators seeking to integrate generative AI tools effectively into language education.

Published: July 2024

This study examines the perspectives of university faculty and staff regarding the influence of artificial intelligence on the higher education teaching and learning landscape following the global launch of free-to-use OpenAI ChatGPT in the autumn of 2022. The participants were 79 university faculty and staff from diverse academic fields across all campuses of a multidisciplinary university in Finland. The data were collected in two phases in May–June 2023 and in March 2024, with focus group interviews and Learning Café discussions. The results showed that AI has a broad impact on teaching and studying in higher education. Six main categories were identified: (1) the impact of AI on students’ learning processes, (2) the impact of AI on teaching, (3) the knowledge required of future employees and the impact of AI on them, (4) ethical and economic issues, (5) the development of AI or its use in the future, and (6) the nature of the change brought about by artificial intelligence. AI is already making inroads into higher education, and participants underscored its dual impact on teaching and learning, highlighting both opportunities and challenges. While teachers recognized AI’s potential to enhance teaching and assessment methods, they also acknowledged the need to adapt their courses accordingly. They expressed concerns about understanding AI’s impact on students’ learning processes and their own contributions to learning assignments. The participants emphasized the necessity of providing support and training for teachers to ensure AI is meaningfully and effectively integrated into teaching and learning practices and landscapes.
Reduced Graphene Oxide Decorated Titanium Nitride Nanorod Array Electrodes for Electrochemical Applications
Authors: Islam Md Shafiul , Branigan Alan , Ye Dexian , Collinson Maryanne M.
Published: July 2024

This work describes the fabrication and characterization of a new high surface area nanocomposite electrode containing reduced graphene oxide (rGO) and titanium nitride (TiN) for electrochemical applications. This approach involves electrochemically depositing rGO on a high surface area TiN nanorod array electrode to form a new nanocomposite electrode. The TiN nanorod array was first formed by the glancing angle deposition technique in a DC (Direct Current) sputtering system. GO flakes of ~1.5 μm in diameter, as confirmed by Dynamic Light Scattering (DLS), were electrodeposited on the nanostructured TiN electrode via the application of a fixed potential for one hour. The surface morphology of the as-prepared rGO/TiN electrode was evaluated by scanning electron microscopy (SEM) and the presence of rGO on TiN was confirmed by Raman Microscopy. The CV shows an increase in the capacitive current at rGO/TiN as compared to TiN. The rGO decorated TiN electrode was then used for analyzing the electrocatalytic oxidation of ascorbic acid and dopamine, and the reduction of nitrate by CV and linear sweep voltammetry (LSV), respectively. CV or LSV show that the electrochemical kinetics of these three analytes are significantly faster on rGO/TiN than TiN itself. Overall, the rGO/TiN electrode showed better electrochemical behavior for biomolecules like ascorbic acid and dopamine as well as another target analyte, nitrate ions, compared to TiN by itself.
Harmonic Self-Compensation Control for Bidirectional Grid Tied Inverter Based on Crown Porcupine Optimization Algorithm
Authors: Tian Ao , Zhang Fenghui , Xiao Peng
Published: July 2024

A self-compensating control strategy for harmonic parameters based on the crown porcupine optimization algorithm is proposed for the single-phase rectifier and two-phase inverter operation mode of the bidirectional converter. In order to improve the response speed of the inverter voltage, the instantaneous expressions of the phase angle coefficient and amplitude coefficient of the dc-side voltage doubling fluctuation are derived, and the third harmonic is calculated based on the crown porcupine optimization algorithm according to the Proportional Integral (PI) + Quasi-Proportional Resonance (QPR) double closed-loop control method and injected into the input voltage of the inverter side to offset the influence of the bus-doubling fluctuation on the output voltage of the two-phase inverters of B and C so that the total harmonic content of the two-phase output voltages of the two-phase inverters of B and C can be reduced. The total harmonic content of the B and C inverter output voltages is reduced. The effective control of the control method for single-phase rectifier two-phase inverter mode is verified through simulation. Finally, the effectiveness of the control strategy is verified by experimenting with a 15 kW LCL-type bi-directional converter prototype.

Authors: Lee Yonghwa , Castellazzi Alberto , Domae Shinichi
Published: July 2024

This paper is about the development and demonstration of a motor drive for e-transport applications based on an innovative hybrid Si-SiC dual switching frequency interleaved buck–boost Y-inverter and a single-rotor Halbach machine. In particular, the focus is the implementation of the required discontinuous inverter modulation scheme, input voltage feed-forward and motor currents feedback control loops, as well as over-voltage, over-current, and over-temperature protections, using an off-the-shelf commercial hardware platform enabling straightforward Simulink-environment programming of all parts, while ensuring the high switching frequency capability required by wide-band-gap semiconductors. Experimental results showed good inverter efficiency, transient dynamic response to load changes, input voltage regulation, and fully functional protection capability, validating the proposed approach as a powerful option for reducing system development time and cost.
On the Determination of Efficiency of a Gas Compressor
Authors: Millar Dean L.
Published: July 2024

For a gas undergoing a compression process, it is more appropriate to think of either isentropic or polytropic efficiency as process-defining parameters indicating that a given end state of compression has been achieved, rather than a measure of effectiveness of conversion of one form of energy into another. The polytropic efficiency, as defined in ASME PTC-10 standard for compressor field trials and acceptance tests, actually involves the comparison of two distinct compression processes, neither of which are actually connected to the performance of the compressors producing them. Consequently, it is not rational to compare the ASME PTC-10 polytropic efficiency of a compressor designed to compress a gas predominantly adiabatically with that for a compressor designed to compress a gas predominantly isothermally. A framework correcting this situation is set out and is illustrated with several numerical examples. Suggestions for maintaining backward compatibility with ASME PTC-10 are also put forward.

Interval Assessment Method for Distribution Network Hosting Capacity of Renewable Distributed Generation
Authors: Wan Dai , Peng Simin , Zhang Haochong , Diao Hanbin , Li Peiqiang , Tu Chunming
Published: July 2024

The traditional fixed value assessment of the renewable distributed energy hosting capacity of a distribution network cannot accurately and comprehensively reflect the change in hosting capacity; therefore, we propose the interval assessment method for the renewable distributed energy hosting capacity of a distribution network. The renewable distributed energy hosting capacity interval consists of an optimistic upper boundary and a pessimistic lower boundary. First, the optimistic upper bound is described by a deterministic model that takes into account the constraints of safe system operation. Second, the pessimistic lower bound is portrayed by a two-layer robust assessment model that accounts for the DG temporal uncertainty, DG spatial uncertainty, and active distribution network flexible resource dispatch uncertainty. Each pessimistic sub-model was constructed in turn, and then the model was solved by linear simplification using pairwise transformation, as well as McCormick relaxation. Finally, simulations were carried out in the IEEE 135 system, and the results validated the effectiveness and practicality of the proposed method.
Audit Partner Characteristics and Their Impacts on Audit Quality: Evidence from around the World
Authors: Jiang Lingting , Rundo Janean , Shi Linna , Zhou Nan
Published: July 2024

Public company audits are not homogenous. Varying audit partner attributes, including gender, age, location, and expertise, play important roles in explaining audit outcome disparities. The extant literature underscores the influence of firm-level and office-level differences, in areas such as size, culture, and industry expertise, in shaping audit outcomes. Commonwealth countries, such as the U.K., Australia, New Zealand, and Continental European countries, along with Asian economic entities, mandate the disclosure of audit partner names. Consequently, significant research efforts have been devoted to investigating the impact of audit partner characteristics on audit outcomes in these jurisdictions. With the adoption of Public Company Accounting Oversight Board (PCAOB) Rule 3211, mandating disclosure of audit engagement partner details for U.S.-registered public accounting firms on Form AP, there has been a surge in U.S. firm research exploring the significance of audit partner characteristics on audit outcomes in recent years. This paper outlines research that considers audit partner attributes’ influence on audit partner selection and audit quality across different economic entities. This entry contributes by synthesizing findings from recent research across diverse economic contexts, including the recently available insights from U.S.-based audits. The analysis of this entry not only provides insights into the current state of audit partner research but also delineates avenues for future research on this topic.
Pomegranate Quality from Consumers’ Perspective: Drivers of Liking, Preference Patterns, and the Relation between Sensory and Physico-Chemical Properties
Authors: Pons-Gómez Ana , Delpozo Bárbara , Bartual Julián , Besada Cristina
Published: July 2024

Acquiring information on consumer preferences for the sensory properties of pomegranates is a cue for breeding programmes to set their quality targets and promote the consumption of this particularly healthy fruit. In this study, a total of 12 pomegranate varieties were evaluated, including commercial (Valenciana, Illina, Tastem, Rugalate, Wonderful, Mollar 49 y Mollar 45) and new varieties (Ref 102, Ref 383, H3/27, and D27/12). For the first time, consumers not only scored their acceptance of different pomegranate varieties but also described their sensory properties using CATA questions. This approach allowed us to identify the main drivers of liking, preference patterns, and the relationship between sensory and physico-chemical properties. Of all the sensory attributes, acidity intensity was revealed as the main driver of liking/disliking, and two different consumer preference patterns were identified: ‘low acid pomegranate lovers’ and ‘acid pomegranate lovers’. Seed properties like the intensity of woody flavour and seed/aril ratio were also key drivers for preferences. A relationship between sensory and physico-chemical properties was also established. Interestingly, sweetness perception correlated more strongly with low titratable acidity levels than with high total soluble solids levels, corroborating that acidity level is a key measurement for quality assessments. ‘H3/27’ was the most promising of the new varieties for having the well-appreciated internal properties of the ‘Mollar’ varieties and external and internal red colouration, which makes it much more appealing to consumers. This study shows that there is still room on the market for pomegranate varieties with very different sensory properties and highlights the need to develop sensory labels that help consumers make the right choices.

Published: July 2024

Streptococcus suis is one of the most important zoonotic pathogens causing serious diseases in both pigs and humans, especially serotype 2. In northern Thailand, there is a notable prevalence of S. suis infection in humans and transmission has occurred mainly through the consumption of raw pork products. Despite the continued practice of consuming raw pork in this region, limited data exist regarding S. suis contamination in such products. Therefore, this study aimed to assess the prevalence of S. suis and S. suis serotype 2 in retail raw pork meat and edible pig organs sold in Chiang Mai city, Thailand. A total of 200 samples, comprising raw pork meat and edible pig organs, were collected from nine fresh markets in Chiang Mai city between May and July 2023. Samples were prepared and cultured in Todd-Hewitt broth. Bacterial DNA was extracted and tested for any serotypes of S. suis and serotype 2 using loop-mediated isothermal amplification (LAMP) techniques. The study revealed contaminations of S. suis and serotype 2 at rates of 84% and 34%, respectively, with a higher prevalence observed in pig organs compared to raw pork. Both S. suis and serotype 2 were detected across all nine fresh markets investigated. The prevalence of S. suis remained consistently high throughout the study period, whereas serotype 2 showed peaks in May and July. These high rates of contamination indicate that people who consume or work in close contact with raw pork or edible pig organs are at a high risk of S. suis infection. Urgent implementation and maintenance of food safety campaigns and public health interventions are crucial for disease prevention and control.

Authors: Lin Xudong , Cao Zhiqi , Zhang Jiaxin , Mu Guangqing , Jiang Shujuan
Published: July 2024

The mixed yogurt was fermented from Cow–Soy milk and modified by transglutaminase (TG). The effects of mixed milk and TG on the quality characteristics of mixed yogurt were investigated by texture characteristics, rheology (rheometer) and structure (scanning electron microscopy). The findings revealed that the mixed yogurt with 50% cow milk exhibited lower hardness, viscosity and consistency. Furthermore, when TG was added, the yogurt showed better rheological properties, sensory score and a more stable microstructure. Compared with the samples without TG modification, the viscosity and cohesiveness of the modified samples increased by 10% and 100%, respectively. The combination of cow milk and soy milk improved the texture of yogurt, and the TG addition further improved the physicochemical properties of yogurt. This finding provided a meaningful reference for the development of mixed yogurt with a suitable taste from animal and plant milk, and laid a basis for the practical application of mixed yogurt in the dairy industry, which will meet the requirements for dairy products for consumers in future.
Flavor Variations in Precious Tricholoma matsutake under Different Drying Processes as Detected with HS-SPME-GC-MS
Authors: Zhang Fengming , Lu Bin , He Xinhua , Yu Fuqiang
Published: July 2024

By employing headspace solid-phase microextraction gas chromatography–mass spectrometry (HS-SPME-GC-MS), this study displayed the compositional changes in volatile organic compounds (VOCs) in Tricholoma matsutake samples subjected to hot-air drying (HAD) and vacuum freeze-drying (VFD) processes from their fresh samples. A total of 99 VOCs were detected, including 2 acids, 10 aldehydes, 10 alcohols, 13 esters, 12 ketones, 24 alkanes, 14 olefins, 7 aromatic hydrocarbons, and 7 heterocyclic compounds. Notably, the drying process led to a decrease in most alcohols and aldehydes, but an increase in esters, ketones, acids, alkanes, olefins, aromatic, and heterocyclic compounds. Venn diagram (Venn), principal component analysis (PCA), and partial least squares-discriminant analysis (PLS-DA) analyses enabled an easy and rapid distinction between the VOC profiles of T. matsutake subjected to different drying methods. Among the identified VOCs, 30 were designated as marker VOCs indicative of the employed drying process. And the VFD method was more capable of preserving the VOCs of fresh T. matsutake samples than the HAD method. Benzaldehyde, 1-Octen-3-ol, 3-Octanol, and (E)-2-Octen-1-ol were identified as markers for FRESH T. matsutake. Conversely, (E)-3-Hexene, lavender lactone, and α-Pinene were associated with VFD T. matsutake. For HAD T. matsutake, olefins, pyrazine, and esters, particularly ocimene, 2,5-Dimethyl-pyrazine, and methyl cinnamate, significantly contributed to its particularities. The results from this present study can provide a practical guidance for the quality and flavor control of volatile organic compounds in preciously fungal fruiting bodies by using drying processes.

Published: July 2024

The effects of dynamic high-pressure microfluidization (DHPM at 400 MPa) and heat treatment (HT) on the microbial inactivation, quality parameters, and flavor components of not-from-concentrate (NFC) cucumber juice were investigated. Total aerobic bacteria, yeasts and molds were not detected in the 400 MPa-treated cucumber juice. Total phenolic content increased by 16.2% in the 400 MPa-treated cucumber juice compared to the control check (CK). The significant reduction in pulp particle size (volume peak decreasing from 100–1000 μm to 10–100 μm) and viscosity increased the stability of the cucumber juice while decreasing the fluid resistance during processing. HT decreased the ascorbic acid content by 25.9% (p < 0.05), while the decrease in ascorbic acid content was not significant after 400 MPa treatment. A total of 59 volatile aroma substances were identified by gas chromatography–ion mobility spectrometry (GC-IMS), and a variety of characteristic aroma substances (i.e., valeraldehyde, (E)-2-hexenal, (E)-2-nonenal, and (E,Z)-2,6-nonadienal, among others) were retained after treatment with 400 MPa. In this study, DHPM technology was innovatively applied to cucumber juice processing with the aim of providing a continuous non-thermal processing technology for the industrial production of cucumber juice. Our results provide a theoretical basis for the application of DHPM technology in cucumber juice production.

Published: July 2024

The objective of this study was to examine the impact of lactitol on constipation caused by loperamide in Sprague Dawley rats, with a particular emphasis on its underlying mechanisms and potential health advantages. The lactitol effectively improved fecal parameters, intestinal tissue structure, and the expression of constipation-related gene expression and proteins. Lactitol alleviated fecal weight and water content altered by loperamide and enhanced gastrointestinal transit. The administration also restored mucosal and muscular layer thickness. Mechanistically, lactitol upregulated the mRNA expression and/or protein levels of mucins (MUC2 and MUC4), occludin, claudin-1, and zonula occludens, indicating improved intestinal barrier function. Lactitol positively regulated the composition of cecal microbiota, leading to an increased relative abundance of Bifidobacterium, Lactobacillus, and Romboutsia. Conversely, lactitol decreased the relative abundance of Prevotella, Aerococcus, Muribaculum, Blautia, and Ruminococcus. This study demonstrated the potential of lactitol to relieve constipation by modulating the gut microbiota. These findings suggest that lactitol is an alternative to traditional laxatives and has potential as a health-promoting food sweetener.
Vulnerability and Dependence in Slavery and Post-Slavery Societies: A Historicisation of the Enslaved Children (Pon Pekpen) from the Bamum Kingdom (West Cameroon)
Authors: Sylvain Mbohou
Published: July 2024

This article is a reflection on the history of enslaved children (Pon pekpen) in African slavery and post-slavery societies, such as the Bamum Kingdom. This traditional monarchy of the Grassfields of Cameroon, founded in 1394 by Nchare Yen, was one of the largest providers of captives transported to the Atlantic coast and used locally to meet the needs of traditional slavery. In this kingdom, slaves and their descendants, as well as enslaved peoples, represented nearly 80% of the total population. The trade of captives and servile practices left indelible traces, particularly where enslaved children were concerned. So, what did enslaved children represent in African slavery and post-slavery societies, such as the Bamum Kingdom? The aim of this study is to show that the enslaved children were the most vulnerable and dependent members of slavery and post-slavery systems. This study is based on oral, archival iconographic, written and electronic sources, using theories of social dominance and subaltern studies. It clearly shows that the vulnerability and dependence of enslaved children (Pon pekpen) made them special, weak and hopeful links in the slavery system and the persistence of slavery practices. They were mainly victims of traditional slavery and of the trans-Saharan and transatlantic slave trades. Despite the formal abolition of the slave trade and slavery between the 19th and 20th centuries, enslaved children and the descendants of enslaved people continue to be victims of a kind of subalternisation because they are usually considered second-class citizens.

Published: July 2024

Adipocytes are crucial for maintaining energy balance. Adipocyte differentiation involves distinct stages, including the orientation stage, clone amplification stage, clone amplification termination stage, and terminal differentiation stage. Understanding the regulatory mechanisms governing adipogenic differentiation is essential for comprehending the physiological processes and identifying potential biomarkers and therapeutic targets for metabolic diseases, ultimately improving glucose and fat metabolism. Adipogenic differentiation is influenced not only by key factors such as hormones, the peroxisome proliferator-activated receptor (PPAR) family, and the CCATT enhancer-binding protein (C/EBP) family but also by noncoding RNA, including microRNA (miRNA), long noncoding RNA (lncRNA), and circular RNA (circRNA). Among these, lncRNA has been identified as a significant regulator in adipogenic differentiation. Research has demonstrated various ways in which lncRNAs contribute to the molecular mechanisms of adipogenic differentiation. Throughout the adipogenesis process, lncRNAs modulate adipocyte differentiation and development by influencing relevant signaling pathways and transcription factors. This review provides a brief overview of the function and mechanism of lncRNAs in adipogenic differentiation.

Authors: Asgary Ali , Hassan Ali , Corrin Tricia
Published: July 2024

Virtual reality (VR) is a promising new educational and training tool in the field of disaster and emergency management, especially for hazards that are not frequent or well known to the public and require spatial and situational understanding. The objective of this paper is to describe an educational VR simulation that was developed based on a landslide that really occurred in Southern Malawi during the March 2023 Cyclone Freddy. The cyclone induced several landslides that caused many casualties and significant damage. The VR simulation framework consisted of four critical steps using Unity3D for the creation of the simulation including data preparation, terrain and environmental modeling, landslide simulation development, and virtual reality interactions. The simulation scenarios were diversified to include three distinct landscapes that can help users learn how factors such as terrain can influence landslide impacts. The VR simulation offers users an intimate, firsthand experience of the landslide’s unfolding and allows users the ability to explore various facets of the landslide phenomena. This VR simulation aims to provide an educational tool to facilitate an in-depth understanding of and interaction with a real-word landslide to learn about the impacts of landslides and how different factors can influence these impacts.

Hamman’s Syndrome after Vaginal Delivery: A Case of Postpartum Spontaneous Pneumomediastinum with Subcutaneous Emphysema and Review of the Literature
Authors: Olafsen-Bårnes Kristina , Kaland Marte Mari , Kajo Karol , Rydsaa Lars Jakob , Visnovsky Jozef , Zubor Pavol
Published: July 2024

Hamman’s syndrome is a rare condition that mostly affects young males, often with a predisposition to asthma. It includes the presence of free air in the mediastinum and subcutaneous emphysema with no other underlying cause such as trauma, infection, or administration of any sort of mask support with hyperpressure. It occurs spontaneously and often in association with a prolonged Valsalva maneuver. This might explain why there are some cases of Hamman’s syndrome among young females giving birth. Here, we present a case report of a 24-year-old non-smoker primigravida with Hamman’s syndrome. She presented with symptoms a few hours after an uncomplicated vaginal delivery at 40 + 1 weeks of pregnancy where the active phase of labor lasted for three hours with normal progress. The second stage lasted for 30 min, with no signs of distress on CTG. The symptoms (pain in the right ear, swelling and pain in the neck, chest tightness, shortness of breath, dysphagia, odynophagia, and pain in the upper thorax on the right side) and objective findings as subcutaneous crepitations in the neck, parasternal region, right axillary fossa, clavicle and over the chest resolved spontaneously after a few days of observation and conservative management. We also give a systemic review of reported cases since 2000 to provide an overview of the pathomechanism, symptoms, diagnostics, treatment, and management of this condition. Hamman’s syndrome is a rare, usually benign, but potentially serious complication that can occur during the second stage of labor. Diagnostics include inquiring about typical symptoms, clinical examination, and chest x-ray or CT scan. Treatment is usually conservative with oxygen, bronchodilators, and pain relief. The recurrence rate is low and there is no contraindication to vaginal delivery in future pregnancies. However, it is suggested that physicians and midwives be cautious and consider a low threshold for instrumental delivery or cesarean section to avoid excessive Valsalva maneuvers.

Spectroscopic techniques were carried out to identify the dyes used on the famous mediaeval Lady and the Unicorn tapestries kept in the Cluny Museum. Among the six tapestries, La Vue shows a colour variation between the front, which appears blue, and the back, which appears violet, on the Lady’s skirt. In the Middle Ages, it was common for the violet colour to be made with a blue dye bath (woad or indigo) followed by a red bath, which could be madder, cochineal, kermes, or orchil. Since orchil is known to be very unstable to light, its potential use in the original recipe was investigated and a study on this dye was performed. Contactless analyses (hyperspectral imaging in the visible-near-infrared range and UV fluorescence spectroscopy) were carried out on both the tapestry and mock-ups prepared following various mediaeval recipes. The investigation allowed for the identification of woad and orchil on the back of the tapestry, which was preserved from exposure to light. In addition, an ageing study elucidated colour degradation, revealing not only the different responses to light of different dyes but also the effect of specific dye preparations on light resistance. The experiments showed that the longer the maceration, the higher the light resistance of the dye. Furthermore, the red orchil colour fades faster than the woad.
Intangible Heritage and Its Associative Objects as Exemplified by the Materiality of the Portable Material Culture of German Christmas Markets
Authors: Spennemann Dirk H. R.
Published: July 2024

Many aspects of intangible cultural heritage have associated objects of material culture that augment or enable aspects of intangible heritage to be exercised or emphasized. Christmas markets have been publicized as the quintessential event in Germany leading up to Christmas, with the over 2000 locations attracting large numbers of local, domestic, and international visitors. From their origins as mercantile venues during the medieval period, Christmas markets have evolved into multisensory social and experiential events, where the acquisition of Christmas decorations or gifts has been supplanted by the consumption of mulled wine in a social setting. Christmas markets represent intangible cultural heritage staged in ephemeral surroundings. While the abundance of material culture in Christmas markets is widely understood, this focuses on the objects offered for sale at the markets, rather than the objects that characterize a Christmas market and enable its functioning. This paper provides the first comprehensive assessment of the portable material culture associated with the German Christmas markets, covering objects as diverse as payment tokens, lapel pins, special postmarks, beer mats, and commemorative cups issued for the consumption of mulled wine. These objects, as well as numerous other manifestations of material culture, are discussed in the wider framing of the materiality of the markets, examining their ontological qualities within the multiple spheres in which these objects attain meaning (i.e., personal, event, social, and public spheres). It demonstrates that the wide range of alienable material culture associated with German Christmas markets has different manifestations of materiality, depending on the viewpoint of the user (i.e., participant, vendor, organizer), and these manifestations have different expressions of representativeness. On this foundation, this paper examines the various groups of portable and alienable material culture and discusses them in terms of their authenticity and to what extent these are representative of German Christmas markets. While all items have a connection with Christmas markets and function as symbolic shorthand souvenirs, commemorative cups issued for the consumption of hot drinks as well as the deposit tokens associated with these are both genuine and authentic and are also representative of the conceptual, social, and experiential dimensions of the event.
Corporate Social Responsibility, Carbon Information Disclosure, and Enterprise Value: A Study of Listed Companies in China’s Highly Polluting Industries
Authors: Shi Feng , Wang Yuan
Published: July 2024

In 2022, China actively carried out economic transformation and sought high-quality development. To date, enhancing enterprise value is still one of the top priorities for enterprises. Enterprises should take various measures to continuously enhance their value in order to strive for their survival and development. The fulfillment of social responsibilities not only brings benefits to all stakeholders, but also establishes a good corporate image in front of the public and can increase enterprise value. At the same time, in the context of “carbon peaking and carbon neutrality”, carbon information disclosure has an important impact on enterprises and their stakeholders. Taking the data of listed companies within China’s Shanghai and Shenzhen A-share highly polluting industries from 2018 to 2022 as samples, this paper studies the relationship between the level of social responsibility fulfillment, carbon information disclosure, and enterprise value, and makes an empirical analysis. This research finds that social responsibility has a significant positive impact on enterprise value; carbon information disclosure has a significant positive impact on enterprise value; and carbon information disclosure plays a significant positive regulating role in the relationship between social responsibility and enterprise value. Finally, according to the research results, this paper puts forward relevant suggestions from two perspectives: enterprise and government.
Use of Knowledge Graphs for Construction Safety Management: A Systematic Literature Review
Authors: Kong Fansheng , Ahn Seungjun
Published: July 2024

Effective safety management is crucial in the construction industry. The growing interest in employing Knowledge Graphs (KGs) for safety management in construction is driven by the need for efficient computing-aided safety practices. This paper systematically reviews the literature related to automating safety management processes through knowledge base systems, focusing on the creation and utilization of KGs for construction safety. It captures current methodologies for developing and using KGs in construction safety management, outlining the techniques for each phase of KG development, including scope identification, integration of external data, ontological modeling, data extraction, and KG completion. This provides structured guidance on building a KG for safety management. Moreover, this paper discusses the challenges and limitations that hinder the wider adoption of KGs in construction safety management, leading to the identification of goals and considerations for future research.

Background: Virtual surgical planning has become a well-established practice in head and neck surgery. In oncological surgery, it permits the achievement of safe margins resections and ensures functional reconstructions and optimal esthetic outcomes. This study aimed to evaluate the long-term outcomes after virtually planned mandibular microvascular reconstruction, focusing on functional and esthetic results, as well as health-related quality of life. Methods: A long-term retrospective evaluation of 17 patients with oral cavity malignancy who underwent computer-assisted mandibular resection and reconstruction was performed. Functional and esthetic outcomes were analyzed using the EORTC, QLQ-C30, H&N35, and FACE-Q questionnaires. Results: Time since reconstruction ranged from 7 to 14 years. Patients reported high functional levels on the QLQ-C30 functional scales but lower scores on H&N35. On FACE-Q, patients demonstrated higher appraisal and satisfaction with their smiles compared to their overall facial appearance. Conclusions: In this retrospective case series, patients undergoing computer-assisted mandibular reconstruction for oral malignancies achieved good long-term functional and esthetic outcomes. Although limited by the small sample size, these results support the enduring benefits of virtual planning for mandibular reconstruction. To minimize declines in function and appearance, considerations should include immediate dental implants, enhanced reconstruction of the temporomandibular joint, newer methods of radiotherapy to minimize xerostomia, and oral exercises to prevent trismus.
