Authors: Liu Chuanpeng , Song Yanqi , Shen Fuxin , Zheng Junjie , Shao Zhixin , Yang Juntao
Published: June 2024

In tunnel excavation, blasting is widely adopted as an efficient excavation method. However, the influence of vibration on tunnel surrounding rock and support structures during the blasting process cannot be ignored. In this study, based on the background of tunnel blasting construction, we theoretically analyze the reasonable range for selecting the optimal delay time, considering the wave superposition cancellation effect and rock fragmentation effect. We use field measured single-hole waveform and calculate superimposed predicted waveforms for different delay time through linear superposition. This allows us to determine the optimal delay time; it is then validated through numerical simulation and field experiment. The results indicate that, based on the principles of interference vibration reduction and rock fragmentation, the optimal delay time in theory should be in the range of 6.14–8.06 ms. By performing superposition calculation on the measured single-hole waveforms, we determined that the optimal delay time for continuous detonation of cut-holes is 7 ms. The delay time of 7 ms falls within a reasonable millisecond range and it is consistent with the results of numerical simulation. When the optimal delay time was applied to field blasting, the measured vibration waveforms exhibited uniform distribution. Compared to blasting without delay, the peak vibration velocity of the cut-holes decreased from 2.08 cm/s to 0.20 cm/s, and the dominant frequency band shifted from 20 Hz–60 Hz to 30 Hz–120 Hz. This achieved the desired effects of reducing vibration and enhancing frequency. These findings can serve as a reference for future similar engineering projects.
Precision motion control of rotary flexible link manipulators using polynomial input trajectories and feedback control
Authors: Tran Phuc , Bashash Saeid
Published: June 2024

This paper aims to develop a high-precision controller for a flexible link manipulator using polynomial reference, feedforward input, and feedback control. The control objective is to move the tip of the flexible link to a target position as quickly as possible without exciting its resonant modes. Upon a frequency response-based system identification, a frequency-domain feedback controller is designed for reference tracking. The controller includes a proportional-integral controller, a lead filter, and a set of notch filters to control the rigid body and the flexible link dynamics. A set of polynomial reference and feedforward input trajectories are then designed to improve the tracking performance and minimize residual vibrations. The conventional polynomial reference is generated based on the rigid body motion of the system. A revised polynomial reference generation method is then developed by adding flexible motions to the conventional reference. Simulations and experimental tests indicate significant improvements in the performance of the control system using the revised polynomial trajectories.
Finite deformation modeling of wrinkling in thin magnetoelastic sheets
Authors: Mishra Awantika , Santapuri Sushma
Published: June 2024

This paper presents an asymptotic two-dimensional (2D) finite-deformation theory for a thin magnetoelastic sheet starting from a three-dimensional (3D) variational form. This theory is used to model wrinkling phenomena under applied traction and external magnetic field. The resulting 2D potential energy is specialized to an isotropic, in compressible material, and the expressions for material constants, i.e., elasticity tensor, magnetoelastic coupling constant, and permeability, are obtained as a function of the applied magnetic field. The formulation is further simplified assuming reflection symmetry about the mid-surface of the sheet. Strong form of the resulting 2D governing equations are obtained by setting the first variation of potential energy functional to zero. The resulting governing equations are used to analyze wrinkling in a stretched rectangular sheet placed in a uniform magnetic field. Approximate analytical solutions are obtained by linearizing the 2D plate equation for small slopes. The effect of magnetic field and applied stretch on onset of wrinkling and amplitude of wrinkles is studied.
Residual stresses for a new class of transversely isotropic nonlinear elastic solid
Authors: Bustamante Roger , Rajagopal Kumbakonam R , Wineman Alan
Published: June 2024

We study the response of a class of transversely elastic bodies, wherein the Green–Saint Venant strain tensor is a function of the second Piola–Kirchhoff stress tensor, when the body is residually stressed. The notion of such non-Cauchy elastic bodies being transversely isotropic is defined in Rajagopal (Mech. Res. Commun. 64, 2015, 38–41), and by a body being residually stressed, we mean the interior of the body is not in a stress-free state although the boundary is free of traction as considered by Coleman and Noll (Arch. Ration. Mech. Anal. 15, 1964, 87–111) and by Hoger (Arch. Ration. Mech. Anal. 88, 1985, 271–289).

Published: June 2024

Mangoes contain several components that are beneficial for health, in addition to being potential sources of starch for the food industry. However, a substantial amount of fruit is lost in the field because it does not meet commercial standards, resulting in food losses and environmental damage. Herein, the physicochemical properties of mango flours and starches obtained from different parts of the fruit of two cultivars were evaluated. Mango peel flours have higher levels of proteins, fibers, minerals, carotenoids, ascorbic acid, and antioxidant activity than pulp flours, in addition to a higher yellowing index and water and oil-holding capacity, and can be used as a functional flour. The pulp flours, with the higher starch content, showed characteristics that make them valuable as a potential ingredient in soft baking and gluten-free products. Mango starches have circular and oval shapes, with a bimodal distribution. All starches showed an A-type crystallinity pattern. Pulp starches showed a higher peak viscosity and breakdown, with a lower setback, and can be used as a thickening or gelling agent. The higher thermal stability of kernel starch suggests its application in sauces, baking, dairy products, and canned foods.
Feline aortic thromboembolism: recent advances and future prospects
Authors: Guillaumin Julien
Published: June 2024

Practical relevance:

Feline aortic thromboembolism (FATE) is commonly encountered in clinical medicine, especially in emergency situations. This often devastating syndrome usually develops secondarily to severe heart disease, and has short- and long-term consequences.

Clinical features:

The clinical presentation of FATE is consistent with peripheral ischemic neuropathy, usually in both pelvic limbs. Diagnosis is relatively straightforward, but can be assisted with Doppler ultrasound, point-of-care ultrasound or infrared thermal imaging.

Recent advances and future prospects:

Interpretation of survival rates in cats with FATE has been hampered by historically high admission euthanasia, but recent studies suggest a survival rate with supportive care of 30-40%. Moreover, with advances in post-FATE thromboprophylaxis, median survival times of over 1 year are being achieved. Future directions include use of thrombolytic agents and treatment of common FATE sequelae such as acute kidney injury and reperfusion injury.

Outline:

This article, aimed at small animal veterinarians, including emergency practitioners, reviews key aspects of the clinical presentation, diagnosis and treatment options for FATE, with a view to guiding client and veterinarian decision-making. Three case studies are included to illustrate the practical application of information presented in the review.

Evidence base:

There are limited prospective studies on FATE, although the recent literature reflects a resurgence in clinical research interest in the past few years. Advances in FATE treatment will benefit many cats and it is important that research efforts continue to identify appropriate treatment modalities.
Required volume for color flow injection test to confirm the intravascular placement of a peripheral venous catheter
Authors: Kamata Mineto
Published: June 2024

Background:

Confirmation of adequate peripheral intravenous catheter placement is essential before using venous catheters. The color flow injection test has been reported as a method with high sensitivity and specificity for this purpose. The technique involves administrating saline through the peripheral venous route to observe changes in the color flow pattern around the same vein at a more central location. However, the required volume of saline remains uncertain. This study aims to determine the appropriate dosage for conducting the test in pediatric patients and explore any potential correlations between dosage and patient characteristics.

Methods:

A prospective study was conducted in children under 6 years of age with American Society of Anesthesiologists Physical Status 1–2 presenting for general anesthesia. After an intravenous cannula was placed in the forearm under general anesthesia, normal saline was injected at a speed of approximately 1 mL/s while the axillary artery and vein were observed with color flow Doppler imaging. The volume of normal saline required to induce a change in the color flow pattern around the vessels was measured. Measurements were performed twice and averaged for comparison with patient characteristics and other factors.

Results:

The study cohort included 30 patients aged from 0.3 to 5.5 (2.6 ± 1.6) years. The change in color flow Doppler imaging was noted in all the patients, and the average volume was 1.40 ± 0.36 mL (95% confidence interval (CI), 1.27–1.54; p < 0.001), which was significantly correlated with age, with a correlation coefficient of 0.435 (95% CI, 0.09–0.69; p = 0.02).

Conclusions:

The required volume for the color flow injection test is small; therefore, the test is easy to perform and minimally invasive in pediatric patients.

Authors: Wang Liang-Jen , Tsai Ching-Chang , Chao How-Ran , Lee Sheng-Yu , Chen Chih-Cheng , Li Sung-Chou
Published: June 2024

Background:

Exploring the epigenetic regulations, such as microRNA, in newborns holds significant promise for enhancing our ability to address and potentially prevent early-life developmental delays.

Objectives:

Hence, this research seeks to investigate if the expression of miRNA in the umbilical cord blood of infants can forecast their developmental outcomes as they grow older.

Design and method:

We enrolled 143 full-term newborns, delivered either via cesarean section (CS) or through natural spontaneous delivery (NSD). We then analyzed the profiles of specific miRNAs (miR-486-5p, miR-126-5p, miR-140-3p, miR-151a-3p, miR-142-5p, and miR-30e-5p) in the umbilical cord blood of these infants. Subsequently, we performed follow-up assessments using Bayley-III scores when the cohort reached 1 year of age. Furthermore, we conducted pathway-enrichment analyses on the target genes associated with these examined miRNAs.

Results:

When comparing newborns delivered via cesarean section (CS) to those born via natural spontaneous delivery (NSD), we observed notable differences. Specifically, newborns through NSD displayed significantly higher ΔCt values for miR-486-5p, alongside lower ΔCt values for miR-126-5p and miR-151a-3p in their cord blood. At 1 year of age, cognitive development was significantly linked to the ΔCt values of miR-140-3p and miR-142-5p, while language development showed a significant association with the ΔCt values of miR-140-3p. Moreover, our pathway enrichment analyses revealed that the target genes of these miRNAs were consistently involved in the pathways related to neurons, such as axon guidance and the neurotrophin signaling pathway.

Conclusion:

In summary, this study represents a pioneering effort in elucidating the potential connections between miRNA levels in cord blood and the health indicators and neurodevelopment of newborns at 1 year of age. Our findings underscore the significance of miRNA levels at birth in influencing mechanisms related to neurodevelopment.
Exposure And Health Risk Assessment Of Aflatoxins In Hot Red Pepper Marketed In North Shewa Zone, Oromia Region, Ethiopia
Authors: Alemu Degefe Hundessa , Geleta Girma Salale
Published: June 2024

Aflatoxins (AFs) are secondary metabolites mainly produced by Aspergillus flavus and A. parasiticus and their contamination of red peppers can cause hepatocellular carcinoma, growth retardation in children, immune suppression, and death. In addition, their presence in the red peppers can affect international trade and cause significant economic burdens. Thus, the objective of this study was to assess the level of AFs contamination in packed powder (from supermarkets) and raw red pepper samples commercially available in the towns of Fiche and Mukaturi. Furthermore, this study aimed to determine the potential health and cancer risks associated with the consumption of red pepper contaminated with AFs. Red pepper samples (raw and packed powder) were collected randomly from the Fiche and Mukaturi open markets. Then AFs in the samples were extracted using methanol: water (80:20, v/v). These extract samples were then cleaned up using an immunoaffinity column (IAC) and determined with a high-performance liquid chromatography-fluorescence detector (HPLC-FLD). The finding showed that the amount of AFB1, AFB2, and AFG1 in raw red pepper was found to be 3.19 ± 0.01, 0.19 ± 0.001, and 4.07 ± 0.01 μg kg−1, respectively. The raw red pepper samples had a total of 7.66 ± 0.01 μg kg−1 of AFs. On the other hand, the amount of AFB1, AFB2, and AFG1 in Afiya-packed red pepper was found to be 7.04 ± 0.03, 2.15 ± 0.06, and 0.50 ± 0.01 μg kg−1, while Mudayi packed red pepper contained 31.60 ± 0.22, 24.40 ± 0.17, 3.37 ± 0.02 and 2.48 ± 0.004 μg kg−1 of aflatoxins, respectively. Afiya and Mudayi packed powder peppers had a total AFs content of 10.4 ± 0.07 and 61.90 ± 0.28 μg kg−1, respectively. The total AFs concentrations in packed pepper powder samples were higher than maximum toleratable limits (MTLs) set by the European Commission Regulation (EU) 2023/915 (5.00 μg kg−1 for AFB1 and 10 μg kg−1 for total AFs). AFB1 (31.60 ± 0.22 μg kg−1) had the highest level of contamination, followed by AFB2 (24.40 ± 0.17 μg kg−1) in packed pepper powder. In the adult population, the estimated daily intake (EDI) of AFB1, AFB2, AFG1, and AFG2 ranged from 0.80 to 7.90, 0.04 to 6.10, 0.02 to 1.02, and 0.05 to 0.62 [Formula: see text]g kg−1 body weight (bw) per day, respectively. However, the Margins of Exposure (MOE) values and combined Margin of Exposure (MoET) for these chemicals were significantly lower than the safe margin (<10 000). Therefore, this study highlights the potential health risks associated with consuming AFs-contaminated red peppers and the need for stricter regulations and monitoring to ensure food safety.
Association of Exposure to Indoor Air Pollution with Unhealthy Symptoms among Middle-aged and Older Adults in India: Evidence from a Large-scale Survey
Authors: Padma Sri Lekha P , Irshad C V , Abdul Azeez E P , Premkumar A
Published: June 2024

Background:

The usage of solid cooking fuels is widely prevalent in low and middle-income countries, including India, and contributes to indoor air pollution (IAP), which has detrimental health effects. Moreover, time spent inside the house increases as people age. In this context, the present study tried to understand the association between exposure to indoor air pollution and unhealthy symptoms, including shortness of breath, dizziness, headache, fatigue, wheezing, and cough among middle-aged and older adults in India.

Methods:

We extracted the unit-level individual data (N = 63 790) from the Longitudinal Aging Study in India (LASI)-Wave 1 (2017-2018). The statistical analyses used were Chi-square test and binary logistic regression, which estimated the odds ratio to identify the determinants of the unhealthy symptoms.

Results:

The odds of shortness of breath (adjusted OR: 1.14, 99% CI: 1.05-1.23), dizziness (adjusted OR: 1.28, 99% CI: 1.21-1.35), fatigue (adjusted OR: 1.32, 99% CI: 1.26-1.39), wheezing (adjusted OR: 1.30, 99% CI: 1.19-1.42), and cough (adjusted OR: 1.36, 99% CI: 1.27-1.45) were higher among individuals from households where solid cooking fuels was used. Similarly, the odds of shortness of breath, headache, wheezing, and cough were higher among individuals with a household member who smoked inside the house. The results indicated that the odds of shortness of breath, headache, and cough were significantly lower among participants exposed to incense use.

Conclusion:

Based on the results of this study, we suggest developing programs to combat the sources of indoor air pollution and the associated unhealthy symptoms, especially in rural settings. It is also important to bring awareness and practice clean fuel usage at individual and community levels to improve population health.

Published: June 2024

Particulate matter (PM) exposure is associated with adverse health outcomes, including respiratory illness. A large fraction of exposure to airborne contaminants occurs in the home. This study, conducted over 5 months in a community with high asthma rates (Chelsea, MA, USA), investigated the use of portable air cleaners (PACs) to reduce indoor PM. Seven asthma-affected households participated, receiving a PAC (Austin Air Health Mate HEPA filter), a QuantAQ sensor to measure PM1, PM2.5, PM10 (µg/m3), and a HOBO plug-load data logger to track PAC usage. Results describe hourly and daily PM concentrations and PAC usage for each household. Hourly average PM concentrations decreased when PACs were turned on (vs. when they were turned off) across households during the study period: PM1 decreased by 0.46 µg/m3, PM2.5 decreased by 0.69 µg/m3, and PM10 decreased by 3.22 µg/m3. PAC usage varied for each household, including constant usage in one household and only usage at certain times of day in others. Higher filtration settings led to lower PM, with significant reductions in some, but not all, homes. Our findings highlight some difficulties in implementing household PAC interventions, yet also provide evidence to support household-level interventions to reduce PM and other indoor sources of air pollution. We also highlight academic-community partnerships as contributing to evidence-based solutions.
Atherogenic Index of Plasma as an Early Marker of Chronic Kidney Disease and Liver Injury in Type 2 Diabetes
Authors: Li Huifang , Miao Xia , Zhong Jiaoying , Zhu Zhaoming
Published: June 2024

Background:

Diabetic kidney disease (DKD) is the main cause of end-stage renal disease and has a high mortality rate. Currently, no effective treatments are available to reduce the progression of kidney damage associated with diabetes.

Objectives:

To explore the influence and predictive value of the atherogenic index of plasma (AIP) on early chronic kidney disease and liver injury in patients with type 2 diabetes mellitus (T2DM).

Methods:

Medical records of 1057 hospitalized adult patients with T2DM between January 2021 and December 2022 were collected. The predictive value of AIP, renal function, and liver injury in patients with T2DM were analyzed using Pearson’s correlation, multiple logistic regression, and receiver operating characteristic (ROC) curve analyses.

Results:

AIP was a sensitive indicator of early liver and kidney injury in patients with T2DM. Patients in the DKD group showed increased AIP that positively correlated with serum creatinine, uric acid, and β2-microglobulin levels. Increased AIP negatively correlated with estimated glomerular filtration rate (eGFR). AIP significantly correlated with alanine aminotransferase and aspartate aminotransferase levels and glutamyl transpeptidase-to-platelet ratio (GPR). An eGFR of 60-100 mL/min/1.73 m2 significantly increased the risk of DKD as the AIP increased. At lower GPR levels, the risk of DKD significantly increased with increasing AIP. However, no significant difference was found between the 2 groups when the GPR was >0.1407. The ROC curve analysis showed that AIP could predict early liver injury.

Conclusions:

AIP is directly involved in early liver and kidney injury in T2DM and may be a sensitive indicator for early detection.
Gender and eco-domesticity: Are sustainable consumption and a return to the home emancipatory in Czechia?
Authors: Kolářová Marta
Published: June 2024

Recently, there has been renewed interest in homemaking and domestic practices and the revival of domesticity has become related with pro-environmental values and sustainable lifestyles in Western societies. The turn to domesticity tends to be associated with women. While some authors warn of a return to traditional gender roles within the household, others view eco-domesticity as a feminist project that values domestic practices. This article considers the gender-specific aspects of the revival in a post-socialist country and focuses on the gendered aspects of new domesticity. Specifically, it studies the gendered discourses and practices within eco-domesticity in Czechia, which include sustainable consumption, green prosumption and alternative parenting practices. Can the eco-conscious reclaiming of domesticity be viewed as a new form of feminism in Czechia? The study is based on a qualitative sociological research using in-depth interviews, participant observation and media analyses. It is argued here that this new 21st-century domesticity should be understood through the context of the Czech state’s lengthy maternity/parental leave period, which leads to temporary domesticity. The examples of active fathers and self-reliant mothers undermine the traditional division of labour. Caring roles among men in the family are highly valued in eco-domesticity, and alternative gender roles are part of alternative sustainable lifestyles. Care in the home expands to collective activities of parents in community centres and other community projects and decreases the isolation of parents at home. Although inspired by trends from abroad, informants do not perceive eco-domesticity to be a new wave of feminism in Czechia.
Increased perceived safety in day-to-day life relates to critical national identification
Authors: Syropoulos Stylianos , Law Kyle Fiore , Leidner Bernhard
Published: June 2024

National identification consistently predicts attitudes within and between groups. Research indicating that threat perceptions often lead to compliance with ingroup authorities suggests that heightened threat perceptions may contribute to stronger submissive national identification. However, the impact of feeling safe on a more critical (in contrast to submissive) sense of national identification remains largely unexplored. Drawing on social safety theory and attachment theory, the present investigation examined whether individual differences in feeling of safety relate to increased critical and submissive/blind forms of national identification. Studies 1A–1B and 2A–2B utilized nationally representative data from large cross-national surveys, finding that greater perceived safety related to increased pride in, emotional attachment to, and closeness to one’s nation. In Studies 3–5, we found that feeling safe in daily life and believing that one is capable of protecting oneself relate to more ingroup attachment and glorification. Notably, the association for feeling of safety and ingroup attachment was larger than that for ingroup glorification. This investigation offers consistent evidence for a positive association between how safe people feel and national identification, highlighting that more research is needed to better understand how feeling of safety could influence intergroup processes.
Mapping the landscape between pacifism and anarchism: Accusations, rejoinders, and mutual resonances
Authors: Christoyannopoulos Alexandre
Published: June 2024

Pacifism and anarchism share some territory and have cross-pollinated across historical contexts, but are also distinct traditions and movements, with voices in each holding serious reservations and criticisms of the other. Identifying and critically discussing these reservations helps correct widespread misunderstandings in the scholarship and the wider public, thereby also presenting arguments for those outside either tradition to reevaluate their own assumptions and analyses. Anarchist qualms about pacifism and nonviolence include: disputes about the effectiveness of nonviolence; a distrust of the origins and compromises of pacifism and nonviolence; and complaints about the censoring effects of nonviolence in social movements. Pacifist qualms about anarchism include: its support for violence; and its radicality. Each accusation is nuanced or countered with arguments grounded in the indicted tradition. Shared concerns and mutually resonating themes that emerge in the process include: critiques of state violence, militarism and structural violence; and arguments about means as ends-in-the-making.

Authors: Ervasti Jenni , Pentti Jaana , Aalto Ville , Kauppi Maarit , Virtanen Marianna , Kivimäki Mika , Vahtera Jussi
Published: June 2024

Aim:

The aim of this study was to determine the association between neighbourhood socioeconomic disadvantage and teaching staff’s risk of workplace violence and whether workplace psychosocial resources can act as effect modifiers.

Methods:

Primary school teaching staff in the six largest cities in Finland responded to a survey in 2018 and were linked to information on school neighbourhood disadvantage obtained from the national grid database ( n = 3984).

Results:

After adjustment for confounders, staff working in schools located in the most disadvantaged neighbourhoods had a 1.2-fold (95% confidence interval 1.07–1.35) risk of encountering violence or threat of violence compared with staff working in the most advantaged neighbourhoods. The association was less marked in schools with strong support from colleagues (risk ratio 1.14, 95% confidence interval (95% CI) 0.98–1.32 for high support versus 1.23, 95% CI 1.07–1.43 for low/intermediate support), a strong culture of collaboration (1.08, 95% CI 0.93–1.26 versus 1.31, 95% CI 1.12–1.53), high leadership quality (1.12, 95% CI 0.96–1.31 versus 1.29, 95% CI 1.08–1.54), and high organizational justice (1.09, 95% CI 0.91–1.32 versus 1.29, 95% CI 1.09–1.52).

Conclusions:

The association between school neighbourhood and teaching staff’s risk of violence was weaker in schools with high workplace psychosocial resources, suggesting that targeting these factors might help in minimizing violence at schools, but future intervention studies are needed to confirm or refute this hypothesis.

Published: June 2024

Patients with rare diseases commonly suffer from severe symptoms as well as chronic and sometimes life-threatening effects. Not only the rarity of the diseases but also the poor documentation of rare diseases often leads to an immense delay in diagnosis. One of the main problems here is the inadequate coding with common classifications such as the International Statistical Classification of Diseases and Related Health Problems. Instead, the ORPHAcode enables precise naming of the diseases. So far, just few approaches report in detail how the technical implementation of the ORPHAcode is done in clinical practice and for research. We present a concept and implementation of storing and mapping of ORPHAcodes. The Transition Database for Rare Diseases contains all the information of the Orphanet catalog and serves as the basis for documentation in the clinical information system as well as for monitoring Key Performance Indicators for rare diseases at the hospital. The five-step process (especially using open source tools and the DataVault 2.0 logic) for set-up the Transition Database allows the approach to be adapted to local conditions as well as to be extended for additional terminologies and ontologies.
Scholarly communication between health informatics and information systems: A bibliometric study
Authors: Lin Angela , Ford Nigel , Willett Peter
Published: June 2024

The challenges of IT adoption in the healthcare sector have generated much interest across a range of research communities, including Information Systems (IS) and Health Informatics (HI). Given their long-standing interest in IT design, development, implementation, and adoption to improve productivity and support organisational transformation, the IS and HI fields are highly correlated in their research interests. Nevertheless, the two fields serve different academic audiences, have different research foci, and theorise IT artifacts differently. We investigate the dyadic relationship between health information systems (HIS) research in IS and HI through the communication patterns between the two fields. We present the citation analysis results of HIS research published in IS and HI journals between 2000 and 2020. The results revealed that despite the two fields sharing a common interest, communication between them is limited and only about specific topics. Potentially relevant ideas and theories generated in IS have not yet been sufficiently recognised by HI scholars and incorporated into the HI literature. However, the upward trend of HIS publications in IS indicates that IS has the potential to contribute more to HI.
Development of a textile sheet mask design for facial care based on a 3D face model of an average woman
Authors: Rudolf Andreja , Šterman Sonja , Cupar Andrej
Published: June 2024

Facial cosmetics moisturise the skin and remove sebum and impurities to maintain healthy skin. Face masks are available on the market in various forms such as gel, emulsion, sheet and paste. The textile sheet mask for facial care is used by all women, regardless of age. This study deals with 3D scanning of women’s faces to create an average female 3D face model for the development of a textile sheet mask design for facial care. Screened Poisson surface reconstruction was used to create an average female 3D face model whose dimensions correspond to average dimensions of scanned female faces. A reliable average 3D face model of the women studied was therefore used to develop a textile sheet mask for facial care. A comparison of average facial measurements with the measurements of randomly selected masks on the market revealed differences. Therefore, a design for a textile sheet mask was developed based on average facial measurements and the average 3D face model of a woman and by using virtual prototyping. The use of software for prototyping and simulating the appearance of clothing has also proven to be effective in the development of a textile product such as a textile face mask. The developed pattern design of the textile sheet mask with optimal dimensions and shape adapts to the contours of an average woman’s face. This fulfils all the requirements for wearing comfort of the textile sheet mask around the eyes, nose and lips during facial care and enables efficient transfer of the serum from the textile sheet mask to the skin.

Authors: Morrison Kerry A. , Rocks Madeline C. , Comunale Victoria , Desai Karan , Nicholas Rebecca S. , Azad Ali , Ayalon Omri , Hacquebord Jacques H.
Published: June 2024

Background:

This study investigates whether open distal radius fractures (ODRFs) treated after 24 hours from time of injury have an increased risk of infection or overall complication profile compared with those treated within 24 hours.

Methods:

Retrospective review was performed of all patients treated for ODRF over a 6-year period at a single large academic institution. Postoperative complications included surgical site infections, need for revision irrigation and debridement, delayed soft tissue healing, loss of reduction, nonunion, and malunion.

Results:

One-hundred twenty patients were treated for ODRF. Mean (SD) age at time of injury was 59.92 (17.68) years. Twenty patients (16.7%) had postoperative complications. Regarding mechanism of injury, 78 (65.0%) had a low-energy and 42 (35.0%) had a high-energy injury. Age and fracture grade were not significant factors. Mean (SD) open wound size was 1.18 (1.57) cm. Mean (SD) time from injury presentation to the emergency department (ED) and first dose of intravenous antibiotics was 3.07 (4.05) hours and mean (SD) time from presentation to the ED and operative treatment was 11.90 (6.59) hours, which did not show a significant association with postoperative complications. Twenty-four patients (20.0%) were treated greater than 24 hours after presentation to the ED, which was not significantly distinct from those treated within 24 hours.

Conclusion:

Patients with ODRFs treated after 24 hours were not associated with a greater risk of postoperative complications. Factors including age, energy and mechanism of injury, and fracture grade did not alter outcome in any statistically significant manner.

Published: June 2024

A small rock shotcrete robot is applied in the deep tunnel dynamic disaster physical simulation system in order to simulate the final operation process of the tunnel project. The robot’s spraying operation and control include many kind of factors. In this paper, the main parameters affecting the spraying operation are analyzed by establishing the spraying model and coating growth model. For matching reasonably the spraying parameters, the matching equation of spraying quality and spraying gun parameter model and spraying feed speed has been derived. Based on the matching equation, the spraying gun structure and robot control system are designed, and the spraying distance and spraying gun movement velocity including horizontal and vertical driving have been controlled better. On the basis of theoretical analysis, a small rock hole shotcrete robot prototype has been developed and the spraying experiments have been finished. The experimental results showed that the model and equation established can guided the spraying quality control. With the increase of the injection elevation angle, the length of the long and short axes of the elliptic coating becomes larger, and the average thickness of the coating center is between 2.23 and 2.34 mm, which meets the design index of the injection robot. The rock hole shotcrete robot meet the design requirements.
Postmemorial work of moral valence: A study of the resistance practices of Ingrian descendants
Authors: Kähäri Outi
Published: June 2024

In this article, I use narrative analysis to examine practices of postmemorial resistance to oppressive authorities in interviews with descendants of Ingrian Finns. The themes that were important to the interviewees concerned questions of historical and contemporary social injustice activated by family memory. My two case studies, based on biographical data collected in Finland in 2020–2021, reflect Ingrians’ descendants’ experiences of marginalization, based both on their inherited family memories of oppression and on their own experiences of having a different family story than those of the social majority. My analysis reveals how the postmemorial work of the descendants of Ingrians is socially, politically and temporally expansive. In contrast to Hirsch, I argue that postmemory, as processed in acts that I conceptualize as postmemorial expressive and rhetorical resistance practices, reflects an identity position.
Fandom as Method: Decolonising Research on Social Media Communications Through Chinese Transnational Fandoms of a Japanese Olympic Figure Skater
Authors: Chen Zhen Troy , Cameron Jackie , Liu Nancy Xiuzhi
Published: June 2024

This paper focuses on international sports personality in figure staking Yuzuru Hanyu, who plays for Japan, and his transnational fandoms in China, to examine the politicisation of his evolving fandom during and after his performance at the 2022 Beijing Winter Olympics. Our contribution is to illustrate the value of analysing fandoms in the Chinese social media as a method that seeks to advance a decolonised approach to communication studies. This study uses digital ethnography to collect data and conducts critical thematic analysis to illustrate the complexity of socially mediated fandom debates and flames. Consulting interdisciplinary literature in sports fandom and communication, athletic branding, and political communication, we propose a fresh critical approach to Chinese communication studies, which we have conceptualised as “fandom as method.” We offer a case study to illustrate this critical approach, which we argue is a contribution to decolonising scholarship by promoting inclusivity of alternative approaches, in communication studies in the global south. “Fandom as method” can excavate new terrain, rather than simply adding to West-centric theoretical advances. Findings underscore that critically analysing the complex interplay between fans, anti-fans, and the authorities through “fandom as method” can reveal previously undetected communication patterns. More importantly, fandom as method can help us interrogate the nuances of communications situated within complex, dynamic, evolving patriotic and nationalistic social media discourses. This approach helps to explicate opaque clashes of “mainstremeist belief and action” in the name of patriotism and nationalism which, in the Chinese context, are subject to intervention from the authorities as the ultimate other. It reveals how social media activity politicises a sports personality, a fandom trend that seems likely to spill over into other spheres of the entertainment industry.
“I Feel Like I am Part of Something Bigger Than Me”: Methodological Reflections From Longitudinal Online Participatory Research
Authors: Power Maddy , Patrick Ruth , Garthwaite Kayleigh
Published: June 2024

This article details methodological reflections and implications for future work from an innovative, participatory research project that started life during the UK’s first COVID-19 lockdown in early 2020. We reflect on the practice, ethical considerations, and challenges of this (necessarily) online participatory research program, which featured intensive, prolonged collaboration with parents/carers living on a low income within the UK. We discuss the ethical-epistemological foundations of the work, specifically a feminist ethics of care and reciprocity, and present our unique methodological approach, detailing how technology was used to collaborate with a diverse, nation-wide community of parents/carers. We discuss our own and participants’ reflections, including the distinctive complexities and advantages of conducting participatory research online, and also the challenges of upholding an ethics of care in an online, participatory space. We highlight the time intensive nature of this work and argue that, within the academy, more needs to be done both to recognize this and to find ways to create space within it for documenting and learning from innovations in the methodology pursued. We conclude with reflections on the new possibilities that emerge when translating participatory principles to online spaces—learnings with clear relevance for others interested in pursuing these approaches.
Legal Issues 101: Implications of Attendance, Absenteeism, and Truancy in the School Setting
Authors: Madura Karen
Published: June 2024

This article is part of Legal Issues 101, a series of topics addressing some common questions and misconceptions about the law and school health. School nurse job responsibilities differ regarding monitoring student attendance and assisting school administrators with required truancy reporting. However, all school nurses support student attendance with a focus on students being safe, healthy, and ready to learn. In this article, the authors address frequently asked questions on topics surrounding student attendance including excused and unexcused absences, truancy, parent/guardian engagement, and related laws.
Intramyelinic edema manifesting as central white matter diffusion restriction associated with brain contusion in pediatric patients
Authors: Nguyen Phuong , Albayram Mehmet , Tuna Ibrahim
Published: June 2024

In traumatic brain injury, white matter diffusion restriction can be an imaging manifestation of non-hemorrhagic axonal injury. In this article, a different pattern of widespread white matter diffusion restriction associated with ipsilateral cortical damage, all noted in pediatric and young adult TBI patients, is presented. Its atypical pattern of distribution and extensive scope on imaging suggest excitotoxicity and intramyelinic edema as possible underlying mechanisms.
Contrast-enhanced 3D black-blood magnetic resonance imaging for diagnosis of cerebral venous thrombosis
Authors: Tunlayadechanont Padcha , Chobaroon Arin , Chansakul Thanissara
Published: June 2024

Purpose

Cerebral venous thrombosis (CVT) is often under-recognized on routine magnetic resonance imaging (MRI) examinations without concomitant magnetic resonance venography (MRV). Contrast-enhanced black-blood MRI (BBMRI) based on a three-dimensional T1-weighted variable-flip-angle turbo spin echo sequence, one of the sequences used routinely in our practice, has the potential for detection of thrombi in patients with CVT. The aim of this study is to evaluate the diagnostic performance and enhancement patterns of contrast-enhanced three-dimensional BBMRI for the diagnosis of CVT.

Materials and methods

Contrast-enhanced BBMRI and contrast-enhanced MRV sequences of 64 patients, acquired from June 2018 to January 2021, were retrospectively reviewed by neuroradiologists for detection of CVT in each venous sinus segment. Diagnostic performance values were calculated for contrast-enhanced BBMRI based on enhancement patterns.

Results

Of 749 venous segments from 64 patients analyzed, CVT was demonstrated in 41 venous segments from 12 patients on contrast-enhanced MRV (CE MRV). Thick wall enhancement and total enhancement patterns were dominantly demonstrated in thrombosed segments. Compared with contrast-enhanced MRV, contrast-enhanced BBMRI had a patient-based sensitivity and specificity of 100% and 98.1%, respectively, and a segment-based sensitivity and specificity of 87.8% and 96.2%, respectively. The positive predictive value of contrast-enhanced BBMRI in detecting CVT was 92.3% (patient-based) and 57.1% (segment-based), and the negative predictive value was 100% (patient-based) and 99.3% (segment-based).

Conclusion

Contrast-enhanced BBMRI has high diagnostic performance in detection and diagnosis of CVT. This sequence may be useful to recognize CVT when dedicated CE MRV was not performed in patients with nonspecific neurological symptoms.
Leveraging digital interactive didactic games to enhance cognitive development in preschool education

Published: June 2024

The objective of this study is to evaluate the capacity of interactive didactic games to augment cognitive development in preschool-aged children and to establish a methodical approach for incorporating these games into early childhood education curricula. The research employs analysis and synthesis methodologies, in addition to induction, deduction, and modelling, to deconstruct and reassemble learning process components cognitively. Interactive games foster cognitive development through the provision of immediate feedback and stimulate learning through entertainment. Nevertheless, commercially accessible games frequently fail to provide suitable educational material. Educators can generate individualised games by employing multimedia tools by a three-part structure for lessons: preparatory, main, and concluding. These games should feature explicit guidelines, captivating narratives, succinct action sequences, specified instructional objectives, and interactivity that is suitable for the age group involved. Scientific accuracy, developmental appropriateness, language comprehension, intuitive navigation, and research/problem-solving abilities are among the proposed selection criteria. Benefits observed in comparison to conventional instruction include increased retention, sustained attention, and problem-solving incentives. By judiciously incorporating sanitary regulations, interactive didactics have the potential to augment child cognition, foster parent-teacher cooperation, and elevate educator prestige. Capitalising on children’s innate fascination with computers for educational purposes establishes a fundamental basis for scholastic achievement. Technology cannot, however, substitute for teacher-student interaction.

Published: June 2024

It is a rare clinical phenomenon when a normal spleen ruptures spontaneously without any prior trauma. We present a 49-year-old male patient who was discovered to have a splenic rupture after he was referred to our facility as a case of unstable angina for cardiac catheterization based on nonspecific electrocardiogram (﻿ECG) abnormalities and symptoms of chest discomfort coupled with abdominal pain and shortness of breath. He received aspirin, clopidogrel, and heparin before arriving at our emergency department. A splenectomy was performed for the patient, and he recovered well. Despite the rarity of spontaneous splenic rupture, physicians must consider it while evaluating elderly patients who are experiencing abdominal pain while on anticoagulants. Splenic rupture should always be considered, and early diagnosis is essential for a better outcome.

Commentary on “Look up! Five research proposals for rethinking marketing in a post-growth society”: Marketing must reflect on its own evolution in the Anthropocene epoch
Authors: Dekhili Sihem , Merle Aurélie , Ochs Adeline
Published: June 2024

This article extends Rémy et al.’s proposal. It proposes to consider the evolution of marketing in the Anthropocene epoch in three stages. Firstly, it goes back to the macroeconomic observations and clarify certain assumptions that are wrongly attributed to Dekhili et al.’s vision of sustainable marketing. Secondly, the article develops the framework of what sustainable marketing practices should be for an organization. Finally, it offers pragmatic guidelines for marketing scholars wishing to conduct research projects in the Anthropocene context.
