AbstractBackground and AimsThe ongoing public health emergency has created incredible fear of getting the infection and a terrible psychological burden among all levels. The pandemic has severely affected private job holders' economic status and lifestyle factors in Bangladesh. Here we aimed to assess fear and depressive symptoms among private job holders in Bangladesh during the Covid‐19 pandemic and associated risk factors.MethodsWe conducted this online cross‐sectional survey between January 15, 2021, and March 15, 2021, among 510 private job holders aged above 18 years. We followed the convenience sampling method for data collection. We assessed sociodemographic factors and two psychometric parameters. We applied the Fear of Covid‐19 Scale and Patient Health Questionnaire‐9 to assess increased fear and depressive symptoms, respectively. Chi‐square test, independent sample t‐test, and binary logistic regression analysis were performed for data analysis.ResultsThe prevalence of increased fear and depressive symptoms were 86.27% and 42.16%, respectively. Factors associated with increased fear among private job holders during COVID‐19 were economic class, obesity, on‐time salary, company's downsizing policy, salary reduction, home office, and transportation facilities. However, depressive symptoms were associated with marital status, education level, residence area, the organizational practice of health safety rules, company performance, on‐time salary, health insurance, downsizing, salary reduction policy, organization type, transportation, and mental health support at work. The present study also noticed some interrelations among the above factors with mental health issues.ConclusionBased on the present findings, we recommend actionable items to improve the mental health of private job holders in Bangladesh due to the ongoing pandemic. Authorities can develop mental health support programs and efficient Covid‐19 response systems. The policymakers and regulatory bodies might take some initiatives to promote mental health in the private sector in Bangladesh.

Published: August 2022

AbstractBackgroundWhile military settings may increase psychological distress, soldiers frequently avoid seeking professional help. This study aimed to examine barriers and facilitators associated with intentions to seek help and actually seeking help from a mental health officer (MHO) and how these differ among soldiers who had sought help in the past and those who had not.MethodThis cross‐sectional study included 263 combat and noncombat soldiers. The Health Belief Model and the Help‐Seeking Model were the theoretical framework used to map the potential variables associated with soldiers' decision to seek help.ResultsStigma and administrative barriers were found to be significant barriers to both the intention to seek help and actually consulting an MHO. These findings were more definitive among combat soldiers. The belief in the effectiveness of mental health treatment was positively associated with the intention to seek help. Positive associations were found between well‐being, perceived seriousness of one's condition, and belief in the effectiveness of mental health care and intention to seek MHO help. Distress and self‐concealment were positively associated with actual consultation with an MHO. Public stigma about seeking help was associated with both the intention to seek mental health assistance and actually consulting an MHO.ConclusionMilitary commanders should make an effort to make soldiers feel safe to seek mental health assistance by creating a supportive organizational atmosphere to reduce the stigma associated with mental health care.

AbstractObjectiveUsing the Interpersonal Theory of Suicide (IPTS) as a framework, this two‐study investigation tested whether burdensomeness and low belongingness explained the association between body and muscle dysmorphia symptoms and suicidal ideation (tested in Study 1 and Study 2), and if fearlessness about death and pain tolerance explained the association between dysmorphia symptoms and previous suicide attempt frequency (tested in Study 2).MethodsStudy 1 used a community sample (n = 273) and Study 2 used an at‐risk population sample (n = 261). Participants completed cross‐sectional questionnaires online.ResultsIn Study 1, both types of dysmorphic symptoms related to suicidal ideation through burdensomeness, but only body dysmorphic symptoms related to suicidal ideation through low belongingness. In Study 2, results were replicated as both types of dysmorphic symptoms related to suicidal ideation through burdensomeness. While both types of symptoms related to low belonging, low belonging did not relate to suicidal ideation. Neither dysmorphic symptoms nor capability for suicide related to frequency of suicide attempts.ConclusionsResults suggest that improving interpersonal needs, such as feeling more effective, may be important treatment targets for individuals with dysmorphic symptoms who also experience suicidal ideation. Future work should continue to identify mediators for suicide attempts among individuals with dysmorphia symptoms.

Published: August 2022

AbstractAdult fans of K‐Pop band BTS are part of a diverse and global fandom that has an evident psychological sense of community associated with psychosocial benefits such as increases in wellbeing. This study aimed to investigate if cyberbullying victimization plays an influential role in the relationship of BTS fans' psychological sense of community and wellbeing using an online co‐designed survey administered to 183 participants. There was a significant positive relationship found between psychological sense of community and wellbeing. The results of a moderation analysis were interpreted as cyberbullying victimization not having an influential role in this positive relationship, despite cyberbullying typically having detrimental effects on interpersonal relationships and communities generally. It was concluded that BTS fans' psychological sense of community may be buffering against the adverse consequences of cyberbullying victimization and/or competent anti‐cyberbullying and online safety practices are being carried out in online BTS fan communities. Implications for anti‐cyberbullying researchers and cyberbullying prevention efforts are also discussed.

AbstractBACKGROUDThe large and growing amount of electronic waste (e‐waste) caused by the rise of the electronics industry has negatively impacted the environment and secondary resource utilization. Thus, research on the recovery, recycling, and reuse of valuable metals from e‐waste has attracted considerable attention. In this study, a novel leaching system based on dicyandiamide ionic liquids (ILs): 1‐ethyl‐3‐methylimidazolium dicyandiamide, 1‐butyl‐3‐methylimidazolium dicyandiamide, and 1‐hexyl‐3‐methylimidazolium dicyandiamide were used to evaluate the effectiveness of leaching gold from typical e‐waste CPUs by iodination.RESULTSThe response surface experiment and analysis of variance (ANOVA) for the results showed that the optimal gold leaching efficiency reached 93.81% after 170 min under a rotational speed of 300 rpm, temperature of 32 °C, and iodine dosage of 1.15%. The mechanism of reaction was determined and the main reaction products were Au[IN(CN)2]− and Au[N(CN)2]2−. Moreover, the kinetic behavior of gold leaching showed a good correlation with the Avrami model and the activation energy value was 14.01 kJ·mol−1. The comparison of iodine consumption between aqueous medium and ILs showed that the required amount of iodine (calculated by ionic iodine) decreased by a factor of six times in ILs.CONCLUSIONThe iodine dosage, leaching temperature, and time had significant effects on the gold leaching efficiency in the IL leaching system. The reaction of gold leaching was jointly controlled by diffusion and chemical reactions. The coordination groups [N(CN)2]22− and [IN(CN)2]2− in the pregnant solution formed stable complexes with Au(I). The consumption of iodine in ILs decreased remarkably, showing the significant practical value of ILs. © 2022 Society of Chemical Industry (SCI).

Published: August 2022

AbstractBACKGROUNDThree‐dimensional and hierarchical porous materials enriched with 2D nanostructure can boost the electrochemical performance of carbon‐based electrodes in the supercapacitor devices. These materials are obtained from novel precursors of palm oil stock biomass. The unique combination of hierarchical and 2D nanostructures was controlled using ZnCl2 impregnation of 0.3–0.9 mol L−1 with high‐temperature pyrolysis.RESULTSImpregnation with 0.5 mol L−1 ZnCl2 (POSC5) produced the highest specific surface area with dominant micropores of 89% in a total volume of 0.343 cm3 g−1. POSC5 was shown to have an excellent morphological combination of trimodal‐foam‐sponge‐like hierarchical porosity with large messy short 2D nano‐rod structures as the optimum carbon preparation. A symmetrical system was designed as a solid electrode without a binder, confirming high capacitive properties of 256 F g−1 in 1 mol L−1 H2SO4 electrolyte with capacitance retention of 76% at 10 mV s−1. The results showed that the transport and resistance behavior of the charge tends to be stable and satisfactory at an internal resistance of 0.012 Ω, with the energy density increased from 9.14 to 21.19 W h kg−1 at 1 A g−1 in 1 mV s−1.CONCLUSIONTherefore, this research provides an environmentally benign and novel approach for developing a high‐quality, sustainable biomass carbon‐based electrode material for electrochemical energy storage applications. © 2022 Society of Chemical Industry (SCI).

AbstractObjectivesForeign body aspiration (FBA) has a wide clinical spectrum, patients may be asymptomatic or present with cardiopulmonary arrest. Radiological imaging methods are used in addition to history and physical examination findings for certain diagnosis. Lung ultrasonography (LUS), whose usage area is increasing year by year, can be included in these. This study aimed to investigate ultrasonography findings in FBA and hypothesized that LUS may have a standard place in FBA diagnosis.MethodsPatients who administered to the pediatric emergency department between August 2019–August 2021, considered according to the clinical findings and physical examination possible FBA, and who undergone rigid bronchoscopy by pediatric surgery were included in the study.ResultsThirty‐two patients were included in the study. According to the results of bronchoscopy, FBA was detected in 25 patients. The most common finding in radiography was hyperinflation on one side, while LUS findings were confluent‐B lines in eight patients, barcode‐sign in five patients, pleural line abnormalities in two patients, and pleural consolidation in two patients.ConclusionThis study is the first study aiming to evaluate LUS findings in FBA to the best of our knowledge. The B‐lines, barcode sign, pleural line abnormalities and consolidation are seen findings in LUS of the patients with FBA. Although it is far from replacing chest radiography in these patients, it is possible to say that it has an equivalent value with chest radiography.
Africa beyond ‘South‐South cooperation’: A frame with limited resonance
Authors: Haug Sebastian , Kamwengo Cynthia M. 
Published: August 2022

AbstractWith reference to frames as socially determined definitions of reality, this paper examines the discrepancies between the prominence of ‘South‐South cooperation’ terminology in globally dominant discourses and its limited usage by African stakeholders. Based on insights from the United Nations, (cross‐)regional collaboration formats and bilateral cooperation, we find that African officials employ ‘South‐South’ terminology mainly when ‘Northern’ partners are present but use other frames when engaging with developing countries. This limited resonance poses a challenge to multilateral organisations and traditional donors in their attempts to expand engagement with ‘South‐South’ relations. A focus on the usage and effects of frames, we argue, can clarify the assumptions based on which international cooperation unfolds.

AbstractBackgroundNanosecond quality‐switched ruby laser (QSRL) and frequency‐doubled 532‐nm picosecond Nd:YAG laser (532‐nm picosecond Nd: YAG laser [PSNYL]) are well‐documented treatments for solar lentigines (SLs). However, no studies have longitudinally tracked the microscopic findings before and after QSRL and 532‐nm PSNYL treatment for SL removal.ObjectivesTo compare the clinical efficacy and dynamic histological changes between QSRL and 532‐nm PSNYL in the treatment of SLs in Asian patients.MethodTwenty‐five patients with SLs on both sides of the face were enrolled in this prospective split‐face study. QSRL and 532‐nm PSNYL therapy for SLs on the left and right side of the face, respectively, were performed for each subject. All subjects underwent baseline and follow‐up assessment at Weeks 3 and 6. In vivo harmonic generation microscopy (HGM) imaging was adopted for the noninvasive observation of melanin mass density of basal cells (MMDbasal cell), epidermal melanocyte dendricity, and dermal melanophages before and after laser treatment.ResultsAt Week 6, 60% of the lesions treated with QSRL and 68% with 532‐nm PSNYL had over 75% improvement. Histologically, both lasers resulted in statistically significant decrease of MMDbasal cell in SLs to the level of that in the normal skin at Weeks 3 and 6. Statistically significant increase of dermal melanophages was observed 3 weeks after both laser treatments. Nevertheless, 532‐nm PSNYL led to faster clearance of melanophages than QSRL at Week 6. Moreover, activated melanocytes with enhanced dendrite formation was significantly increased till 6 weeks after both laser treatments.ConclusionBoth QSRL and 532‐nm PSNYL were effective treatments for SLs, and there was no statistically significant difference in clinical scoring. However, from histological aspect, 532‐nm PSNYL was associated with lower degree of melanin incontinence and melanophage accumulation. HGM imaging analysis can noninvasively quantitate the cutaneous response to pigmentary laser therapy.
Superhydrophobic and Anti‐Icing Coatings Made of Hierarchically Nanofibrillated Polymer Colloids

Published: August 2022

AbstractThe deposition of coatings with hierarchical morphology from hydrophobic and hydrophilic polymers is a common approach for making superhydrophobic and superhydrophilic coatings. The water‐repellent, water‐wicking, and anti‐icing coatings reported here are made from a class of materials called soft dendritic colloids (SDCs). The branched, nanofibrous SDCs are produced in suspension through nonsolvent‐induced phase separation in a turbulent medium. The properties of coatings formed by drying ethanol suspensions of SDCs made of polystyrene, polyvinyl alcohol, and polyester are compared. The highly branched SDC morphology creates entangled, porous coating layers with strong physical adhesion to the substrate due to the multitude of nanofiber sub‐contacts analogous to the “gecko leg effect”. Polystyrene SDC coatings show excellent superhydrophobicity but weaker adhesion due to low surface energy. Alternatively, polyvinyl alcohol SDC coatings show superhydrophilicity and strong adhesion from their high surface energy. Two strategies to improve the adhesivity and cohesivity of the SDCs layers are shown effective – use of intertwined networks and of silicone droplet microbinders. The water repulsion, together with the air trapped in the blended superhydrophobic coatings also makes them effective against ice nucleation and adhesion. Finally, these SDCs make thin, flexible, and durable nonwovens with similar properties.

AbstractAimThe aim of this study was to validate a job satisfaction scale among acute care nurses in the context of Qatar.DesignCross‐sectional correlational survey.MethodsA convenience sampling technique was used to recruit 295 acute care nurses between June 2021–September 2021. Exploratory factor analysis followed by confirmatory factor analysis was used for item reduction and convergent and discriminant validity evaluation. Pearson's correlations were conducted to evaluate the concurrent and convergent validity of the revised scale. Reliability was tested using several internal consistency indicators.ResultsA revised scale was proposed, the Acute Care Nurses Job Satisfaction Scale‐Revised (ACNJSS‐R) scale; it is composed of 13 items loaded on five factors. The composite reliability and the maximal reliability were >.7 for all factors. The study provides empirical support for the validity and reliability of the ACNJSS‐R scale.
Controlling resin flow in Liquid Composite Moulding processes through localized irradiation with ultraviolet light
Authors: Endruweit Andreas , Matveev Mikhail , Tretyakov Michael V. 
Published: August 2022

AbstractA vacuum infusion process was implemented to produce composite specimens from a random glass filament mat and an acrylic modified polyester resin curable upon irradiation with ultraviolet (UV) light. Through localized irradiation with UV light during the reinforcement impregnation, the viscosity of the flowing resin was increased selectively. This allowed converging–diverging flow patterns with defined inclusions to be realized and racetracking along reinforcement edges to be suppressed. The approach is based on radical photopolymerisation. Here, the degree of cure and the viscosity of the resin increase under direct irradiation, such that the resin gels and the flow stalls in a matter of seconds, but remain unchanged in areas covered with an opaque mask. While this study is concerned with the feasibility of the process, potential practical applications are in flow control for Liquid Composite Moulding, that is, compensation for local variations in the fiber volume fraction and permeability of reinforcements.

AbstractObjectiveThe prevalence of depressive symptoms immediately after the diagnosis of colorectal cancer (CRC) is high and has important implications both psychologically and on the course of the disease. The aim of this study is to analyse the association between depressive symptoms and CRC survival at 5 years after diagnosis.MethodsThis multicentre, prospective, observational cohort study was conducted on a sample of 2602 patients with CRC who completed the Hospital Anxiety and Depression Scale (HADS‐D) at 5 years of follow‐up. Survival was analysed using the Kaplan–Meier method and Cox regression models.ResultsAccording to our analysis, the prevalence of depressive symptoms after a CRC diagnosis was 23.8%. The Cox regression analysis identified depression as an independent risk factor for survival (HR = 1.47; 95% CI: 1.21–1.8), a finding which persisted after adjusting for sex (female: HR = 0.63; 95% CI: 0.51–0.76), age (>70 years: HR = 3.78; 95% CI: 1.94–7.36), need for help (yes: HR = 1.43; 95% CI: 1.17–1.74), provision of social assistance (yes: HR = 1.46; 95% CI: 1.16–1.82), tumour size (T3–T4: HR = 1.56; 95% CI: 1.22–1.99), nodule staging (N1–N2: HR = 2.46; 95% CI: 2.04–2.96), and diagnosis during a screening test (yes: HR = 0.71; 95% CI: 0.55–0.91).ConclusionsThere is a high prevalence of depressive symptoms in patients diagnosed with CRC. These symptoms were negatively associated with the survival rate independently of other clinical variables. Therefore, patients diagnosed with CRC should be screened for depressive symptoms to ensure appropriate treatment can be provided.
