Authors: Tsou Hao-Hsuan , Huang Chung-Ching , Chen Yi-Cheng , Shih Syu-Yang
Published: November 2022

Residual stress negatively affects the quality of optical products and is a difficult problem to solve. Regulating process parameters is a critical element in quality control. Therefore, the online monitoring of critical process variables is necessary for stabilizing product quality and reducing manufacturing cost. This study proposes a method for the online monitoring of residual stress near the gate of a mold using multiple pressure sensors to measure process variables and verifies the feasibility of online monitoring. The study found that residual stress near the gate could not be accurately measured with only a single sensor because measurements were susceptible to interference with process parameters. When a single sensor was used to measure process variables, correlation coefficients of between 0.48 and 0.59 were obtained, and when multiple sensors were used, correlation coefficients of between 0.80 and 0.92 were obtained, which indicated strong correlation. Therefore, the online monitoring of residual stress near the gate is feasible. This monitoring method can provide a new concept of online monitoring technology for the injection molding of optical products.

Nanocomposite films based on carbonaceous materials and polymers offer an innovative technological approach for realizing scalable and flexible sensors with high sensitivity and low manufacturing costs. This novel approach leads to sensors; which outperform conventional sensors and have decisive advantages, e.g., adjustable measurement range, high sensitivity, high robustness, flexibility, and scalability. Manifold carbonaceous nano-materials-based sensors having new principles can be realized for measurands such as temperature, humidity, strain, and pressure. These sensors can be realized with low costs without the need for cleanrooms and are affordable even if only a small number of sensors is produced. Due to their flexibility and low layer thickness, they can be easily integrated into materials and structures. In this paper, we provide a critical survey on the potential of sensors based on carbonaceous nanomaterials and polymers and highlight their principles, manufacturing procedures, and resulting properties. We discuss sensor properties going much beyond sensors realized with classical technologies, mainly due to novel principles and outstanding properties of nanomaterials.
“An Isolated Outpost of   Western Civilization”
Authors: Bone Andrew G.
Published: November 2022

On his Australian lecture tour of 1950 Russell talked more about the global dimensions of the Cold War than about the politics, culture and society of the country he was visiting for the first and only time. As a keen but non-specialist observer, however, he readily offered his impressions and opinions of Australia and its place in the world. Like the majority of his hosts, Russell regarded this British Commonwealth state and American ally as an integral if distant part of the “West” and assumed that its comparatively small and overwhelmingly white population could continue to exist largely apart from the region within which it was situated. In so doing, he emphasized Australia’s geopolitical vulnerabilities and demographic challenges, sometimes also displaying a Cold War mindset that remained decidedly anti-Soviet at the mid-century mark. Russell’s reflections on these matters, and the linkages he drew between them, spoke to (rather than questioned) deep-seated Australian anxieties and prejudices about national security, race and immigration.

Abstract. Water flowing in the river causes a scouring event that occurs at the bed channel. The existence of scouring will increase along with changes in the geometry of the river and obstacles such as the weir which are followed by local scouring around the weir. Local scouring often occurs downstream end of weir sill which weakens its construction. Scouring measurement was conducted to monitor the pattern of scouring that occurs. By using Surfer software, the scouring visualization through the Data Grid and 3D Surface can be seen. In this research, scour monitoring in the laboratory using open channels (flume) and MDO weir with fine aggregate material as the basis of the channel. The retrieval of scouring data was performed after installing fine aggregate and three times variations of flow discharge, then the data were processed using Surfer. The first flow used water level +3.50 with the material carried at 3.77%. The second flow used water level +4.50 with the material carried at 11.16%. The third flow used water level +5.70 with the material carried at 25.46%. So with the continuous method, the total material carried at 36.27% is equivalent to 12575.77 cm3.

Purpose - to summarize data from the literature and own experience regarding the course of COVID-19 in children; to determine changes in tolerance to physical activity in children who have experienced COVID-19. The issue of long-term consequences of the transferred COVID-19 is increasingly being raise in connection with the pandemic of COVID-19. The problem of changes in the functional state of the body, health and improving the quality of life of children who have infected COVID-19 is relevant. To analyze these parameters, it is advisable to use the assessment of tolerance to physical activity. Tolerance to physical activity is a total indicator of the body’s physiological capabilities, which allows you to assess the processes of oxygen consumption by the myocardium and myocardial reserves, which are important in the overall adaptation of the body. The «gold standard» of assessing tolerance to physical activity is the determination of the maximum VO2, and other indicators, the control of which in dynamics will allow the development of medical and rehabilitation measures aimed at the elimination of post-COVID symptoms.

Early diagnosis and timely treatment of combined immunodeficiency (CID) is extremely important for the child’s future life. At birth, children often have no specific signs of the disease, but from the first months of life CID manifests by severe infections that can impact on the results of further treatment. Detection of T-cell lymphopenia by determining the number of T-cell receptor excision circles (TRECs) in a dry spot after the birth of a child formed the basis for newborn screening for severe CID. KREC (kappa-deleting recombination excision circle) assay is used for detection of B-cell lymphopenia. Clinical case. We report the first case of CID (T-B+NK+) suspected by detection of TREC in Ukraine in a 2.5-month-old child. Immunodeficiency was manifested by severe complicated pneumonia at the age of 2 months, which had an atypical course and was resistant to treatment. A screening study to detect T- and B-lymphopenia using the TREC/KREC assay twice showed a zero TREC value and a KREC number of 3.12×105 per 106 cells, indicating severe CID. Subsequent immunological studies confirmed the deficiency of T-cell immunity. Venous thrombosis and increasing multiorgan failure led to the death of the child. Thus, newborn screening using TREC assay will allow the timely detection of severe combined immunodeficiencies with further adequate therapy and measures to prevent life-threatening infections, including SARS-CoV-2. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies.

Neonatal sepsis (NS) continues to be the one of the major problems in neonatal practice. This is due to the variability of clinical manifestations and, in part, the lack of available diagnostic markers that are significantly associated with mortality as a result of neonatal sepsis. The purpose - to study the role of paraclinical markers of myocardial dysfunction in neonates with sepsis. Materials and methods. To achieve this goal, 87 newborns (the main group) with manifestations of a generalized infectious-inflammatory process were under our observation. The control group included 30 newborns, in which infectious and inflammatory diseases were refuted. Examination and treatment of patients with NS was carried out in accordance with modern international guidelines and recommendations. Results and discussion. Based on a comprehensive clinical and paraclinical examination of neonates of the main group, it was found that 25 (28.7%) newborns suffered from early sepsis, respectively, the remaining 62 (71.3%) patients had late NS. According to the severity of the condition, 76 (87.4%) children of the main group included in the study required intensive care, which was provided in the neonatal intensive care unit. The average value of procalcitonin in the main observation group was 2.53±0.33 ng/ml, respectively, in the control group - 0.24±0.04 ng/ml (p<0.05).

In recent decades, there has been a steady increase in the prevalence of obesity in children around the world. The low prevalence of obesity in children in Ukraine indicates the underdiagnosis of this disease by doctors. In addition to the generally accepted indicators - body weight, body mass index, for the diagnosis of obesity and prediction of complications is promising to use the data of waist circumference and waist-to-height ratio. Purpose - to study and evaluate the indicators of body weight, height, body mass index, waist circumference and waist-to-height ratio in children in Kyiv at the present stage. Materials and methods. An analysis of the results of the survey of 784 children aged 3 to 18 years. Height, body weight, body mass index and waist circumference were estimated using standard centile tables. To estimate waist-to-height ratio, the limit value was considered to be 0.5. Statistical data processing was performed using MedStat v 5.2 and EZR v1.35. Results and conclusions. The height rates of 56.5% of the surveyed children in Kyiv ranged from 15 to 85 percentiles, 27.3% had excessive height rates and 12.8% exceeded 97 percentiles. Significant short stature was observed in only 0.5% of respondents. Body weight over 97 percentiles was almost twice as common in boys than in girls (p<0.05). BMI in 66.9% of children was within normal limits. Overweight was observed in 13.0% of children, 10.1% of respondents had obesity. Obesity was observed in boys more often than in girls (p=0.02). According to the results of the assessment of the waist circumference in 21.4% of all respondents, the results were found above 90 percentile. Increases in waist circumference were almost twice as common (p<0.05) among boys than among girls (25.4% and 17.3%, respectively). In boys with obesity and overweight, this figure exceeded the norm more often than in girls (p<0.05). The averages waist-to-height ratio was 0.46±0.19 among boys and 0.43±0.07 among girls. Individual analysis showed that the waist-to-height ratio was exceeded in 22.4% of boys and 15.2% of girls. Among boys and girls with obesity, the waist-to-height ratio was exceeded in 58.2% and 58.3%, respectively. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies.

The high prevalence of obesity among children and adolescents at the current stage is an important medical and social problem in pediatric practice. The presence of obesity in children is a significant risk factor for the development of metabolic disorders in the body. Pathogenetic mechanisms of the development of metabolic disorders in obese people remain to be fully understood, but the presence of a chronic inflammatory process in the body is considered to be one of the key factors in their formation. For today, many scientists are studying the state of the intestinal microbiota as one of the likely triggers of chronic inflammation and the development of metabolic changes in obese people. Purpose - to summarize the literature data and the results of our own research on the effectiveness of the therapeutic effect of probiotic cultures on the main metabolic indicators in children with obesity. Results and conclusions. At the current stage, scientific researches on the study the role of intestinal microbiota both as a marker of metabolic changes in the body of obese people and as a potential therapeutic target are continuing. According to systematic reviews, the level of pro-inflammatory cytokines in the body of obese people is significantly increased and pronounced dysbiotic disturbances are noted. Addition of probiotic cultures to therapy has been reported by various researchers to improve basic metabolic parameters and reduce inflammatory markers in obese people. As a result of our own research, improvements in carbohydrate and lipid metabolism indicators, the structural and functional state of the liver, and the general condition of obese children who took a synbiotic drug in complex treatment were revealed. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions.

ABSTRACT The internet has been changing the doctor-patient relationship in the orthopedic area, especially in recent months, due to the COVID-19 pandemic. Objective: To gather information on the use of social networks regarding orthopedics and traumatology, as well as patient opinions on telemedicine. Methods: Cross-sectional study with 237 patients discharged from the orthopedics outpatient clinic of the Odilon Behrens Metropolitan Hospital, in service exclusively for the SUS, answered a questionnaire containing questions related to the use of the internet, social networks, and telemedicine in the current context. Results: Most participants never or rarely look for information on the internet before or after the medical appointment; but when they do, the search results are rarely enlightening. There was a lower demand for information among men when compared with women. There were no significant differences regarding the age of the participants who agreed that most appointments will be carried out over the internet in the future. Conclusion: The search for medical information on social networks is a global reality, but it still generates disagreements regarding its effectiveness and scope. More studies are needed in different orthopedic services for further analysis on the use of social networks within this field. Level of Evidence IV, Case Series.

ABSTRACT Joint stiffness is the most common complication in elbow injuries, presenting several etiologies and pathophysiological mechanisms that hinder treatment and prognosis. Prevention and treatment of joint contracture depend on the cause of stiffness, and early intervention should modify its outcomes. The methods used may be conservative or surgical, alone or in combination, according to each individual situation. Objective: Review articles on articulated elbow orthosis for joint stiffness rehabilitation. Methods: A literature review was conducted in journals available at the PubMed, Medline and LILACS databases, using the following Health Science Descriptors (DeCS): orthotic devices; braces; elbow; elbow joint; contracture; joint disorders. It sought to retrieve and analyze studies with the highest level of evidence that have already been conducted on articulated elbow orthosis for joint stiffness rehabilitation. Results: After applying the inclusion and exclusion criteria, four articles were included from PubMed and none from Medline or LILACS. Of the four PubMed articles, two were systematic reviews and two were randomized clinical trials. Conclusion: Articulated elbow orthoses can benefit joint stiffness treatment, improving range of motion and pain, showing superior effect compared to non-articulated plaster orthotics.

Authors: Oliveira Marcos André de , Oliveira Márcio Santos Sepúlvia de , Miranda Anna Karolyne Souza
Published: November 2022

Resumo A repotenciação é uma opção sustentável para hidrelétricas relativamente antigas. Contudo, ainda encontra-se em um processo de desenvolvimento dos seus aspectos técnicos, socioambientais e regulatórios, no Brasil. Além disso, existem poucos trabalhos disponíveis na literatura sobre o tema. Uma lacuna da área é a falta de metodologias que direcionem a mensuração dos benefícios nos empreendimentos aptos, para priorização dos mais oportunos, redução dos riscos e incentivo dessa prática no âmbito nacional, regional e dos agentes. Neste trabalho apresenta-se uma discussão teórica das práticas atualmente empregadas e propõe-se um método acessível (simples, rápido e de baixo custo) para suporte à tomada de decisão quanto à aplicabilidade da repotenciação em pequenas centrais hidrelétricas. Os resultados explicitam a sustentabilidade ambiental da prática frente às limitações e desafios que envolvem a construção de grandes hidrelétricas, atualmente.

Friend or foe? When political elites evaluate foreign leaders
Authors: Rivas José Manuel , Bohigues Asbel
Published: November 2022

Abstract: Leaders are themselves key actors in international relations; in recent years, Hugo Chávez and Pope Francis have had an expressive impact beyond their respective traditional influence areas. Why do such leaders display this kind of popularity? More importantly, how do political elites perceive them? This paper aims to identify, employing evidence from eighteen Latin American parliaments, what drives political elite evaluations of a variety of notorious leaders in the last decade. To determine which factors are behind their evaluations, we rely on a friend-foe approach of politics, as measured by the ideological distance between the legislator her/himself and the leader. The results point that this friend-foe logic is the main predictor when it comes to the evaluation of elites by elites in the international arena.

Published: November 2022

abstract: Circular Economy (CE) is progressively attracting interest from construction sector stakeholders to support the development of products with higher amounts of recovered materials in order to decrease greenhouse gas (GHG) emissions. Concrete is one of the most used materials in the world and can be produced using waste as raw materials, including, bio-based sources, from both agricultural and forest activities. This research aims to assess the GHG emissions in the life cycle of innovative rice husk bio-concretes (RBC) in which rice husk (RH) and rice husk ash (RHA) are used as circular solutions. Four RBC, considering ordinary Portland cement replacement by 8% of RHA and, different contents of sand substitution by RH (0; 5 and 10%), were assessed. The Life Cycle Assessment (LCA) methodology was used, with a cradle-to-gate scope, using the GWPbio method, that contemplate the influence of biogenic carbon on the emissions reduction. Different transportation scenarios were evaluated considering the RBC production in different Brazilian regions. The service life of RBC in terms of carbon stock was also evaluated. Two carbon-performance indicators are also evaluated in terms of RBC compressive strength and thermal conductivity values. As the main conclusion, cement replacement by RHA alongside with sand replacement by RH are promising strategies to produce bio-concretes for specific applications, such as panels, partitions and façade elements, and to reduce its GHG emissions. However, this benefit varies according to RH availability, transport efficiency and RBC service life. The RBC can be considered a potential alternative for concrete industry, for specific applications, to reduce GHG emissions and can be developed where rice waste is an available source. This study contributes by presenting a new material and a methodology for the evaluation of life cycle GHG emissions of bio-concretes, which can help to promote a circular construction sector.

Authors: Wick Ryan R. , Judd Louise M. , Holt Kathryn E.
Published: November 2022

A perfect bacterial genome assembly is one where the assembled sequence is an exact match for the organism’s genome – each replicon sequence is complete and contains no errors of any scale. While this has been difficult to achieve in the past, improvements in long-read sequencing, assemblers and polishers have brought perfect assemblies within reach. Here we describe our recommended approach for assembling a bacterial genome to perfection using a combination of Oxford Nanopore Technologies long reads and Illumina short reads: Trycycler long-read assembly, Medaka long-read polishing, Polypolish short-read polishing, followed by other short-read polishing tools with manual curation. We also discuss potential pitfalls one might encounter when assembling challenging genomes, and we provide an online tutorial with sample data (github.com/rrwick/perfect-bacterial-genome-tutorial).

Published: November 2022

Cable-stayed bridges (CSBs) are flexible and complex structures. Impact-induced vibrations may play an important role in the behaviours of the structural elements. Much effort has been devoted to clarifying the experimental static and dynamic responses of CSBs. However, experimental dynamic responses of the structural elements of CSBs under impact-induced vibrations have not been widely addressed in the literature. The focus of this paper is on the real experimental dynamic behaviours of cables, decks and pylons in CSBs under impact-induced vibration due to fully loaded trucks passing over a bump positioned on the deck centre. Tests were carried out on the new Kömürhan CSB under the passage of two 40 t trucks travelling at 30 km/h and passing over a timber bump of 50 mm thickness. The dynamic responses of the structural elements were recorded using load cells and two- and three-dimensional accelerometers. Forces, accelerations and frequencies of the main- and back-span cables and the acceleration responses of the deck and pylon, recorded with and without impact effects, were evaluated and compared. Significant impact-induced amplification ratios on the responses of the main- and back-span cables, deck and pylon were observed for the studied bridge.

Authors:   , Cisneros-Guzmán Fernanda
Published: November 2022

Segmentation is vital in Optical Coherence Tomography Angiography (OCT-A) images. The separation and distinc- tion of the different parts that build the macula simplify the subsequent detection of observable patterns/illnesses in the retina. In this work, we carried out multi-class image segmentation where the best characteristics are highlighted in the appropriate plexuses by comparing different neural network architectures, including U-Net, ResU-Net, and FCN. We focus on two critical zones: retinal vasculature (RV) and foveal avascular zone (FAZ). The precision obtained from the RV and FAZ segmentation over 316 OCT-A images from the OCT-A 500 database at 93.21% and 92.59%, where the FAZ was segmented with an accuracy of 99.83% for binary classification.

Published: November 2022

Purpose: This research aims to study whether there is a relationship between stock influencers and financial well-be- ing on stock market participation.
Design/methodology/approach: The research method used in this research is quantitative, with 184 respondents spread over six major islands in Indonesia. The data is processed with SmartPLS 3.0 software.
Findings: The study results show a positive and significant influence between stock influencers and financial well-be- ing on stock market participation mediated by intention to invest. However, the direct relationship between stock influencers and financial well-being to stock market participation was found to have no effect.
Research limitations/implications: This research contributes to the development of financial studies related to capital market participation in Indonesia which is still very limited. The government needs to pay attention to stock influencers and financial well-being, which can significantly impact stock market participation. Socialization and education programs can be carried out informally in collaboration with influencers and focus on increasing knowledge about stocks and managing personal and household finances.

The Effect of Trust and Relationship Commitment on Supply Chain Performance through Integration and Collaboration
Authors:   People&Global Business Association, Jang Kun , Lee Joonkyum
Published: November 2022

Purpose: This study analyzed the effects of supply chain management trust and relationship commitment on financial and non-financial performance, focusing on the mediating effect of supply chain management integration and collaboration.
Design/methodology/approach: This study was designed as a conceptual research model to verify the mediating effect of integration and collaboration in the relationship trust and relationship commitment and supply chain performance. In order to design a conceptual research model, a total 30 items were investigated and the SEM method was verified using six observations variables.
Findings: According to this study, it was found that financial and non-financial performance of companies adopting Korea's supply chain management increased when trust and relationship commitment were strengthened with partner companies. In particular, in the relationship between trust of supply chain management and supply chain management performance, integration with partner companies contributed to increase financial performance, but did not make a positive contribution to non-financial performance. On the other hand, in the relationship between supply chain management's relationship commitment and supply chain management, collaboration made a positive contribution to increasing financial and non-financial performance. What this study means is that higher trust and relationship commitment with partner companies in supply chain management contributed to a direct influence on financial and non-financial performance.
Research limitations/implications: This study used the citation count to measure the effect of trust and relationship on supply chain performance. While this serves the purpose of this study, citation counts may not perfectly represent the value and impact of a study. The findings of this study provide a guide post for future studies.
Originality/value: This study provides an updated, comprehensive literature review of the overall development, contributions and limitations of forecasting studies in the supply chain management fields. The researchers can see the subjects and types of research that already conducted and which topics remain unexamined.
What Determines Saudi Arabia's Development Finance? An Empirical Approach
Authors:   People&Global Business Association, Bokhari Elham , Oh Jinhwan
Published: November 2022

Purpose: This paper empirically examines determinants of Saudi Arabia’s development finance allocation and seeks implications.
Design/methodology/approach: Based on the OLS and Tobit estimation, this paper analyzes a dataset covering Saudi Arabia’s 111 bilateral aid recipient countries during the time period 2015 to 2020.
Findings: This paper finds that Saudi’s aid allocation considers both donors’ interest (DI) and recipients’ needs (RN) given that less populous and relatively lower income developing countries, with strong commercial ties with the Kingdom tend to receive more aid from Saudi Arabia. This result is robust across all the analyses, supported by statistical significance.
Research limitations/implications: Geopolitical factors also matter considering that Arab countries are, on average, receive more aid from the Kingdom while other countries do not, and this confirms Arab solidarity. The Kingdom places a high importance on their non-interference policy in nation states’ sovereignty and their territorial integrity. The Kingdom has a short history as an aid donor. As such, bilateral data is available only since 2015, which is a major caveat in this study.
Originality/value: Existing literature mostly deals with OECD DAC countries in examining aid determinants. This is one of the first studies in this field of literature empirically examining Saudi Aid. This study is expected to shed light to other emerging donors and promote effective South-South cooperation.
Safety Stock Optimization under Lead Time Ambiguity
Authors:   People&Global Business Association, Kim Chong Keun , Kim Pansoo , Kwon Joon Yeop
Published: November 2022

Purpose: The purpose of this study is to investigate how ambiguity faced by the risk-neutral manager affects the firm’s optimal level of safety stock.
Design/methodology/approach: This study adopts the traditional model of Arrow et al. (1951) and employ a manager who has multiple prior beliefs about the probability distribution of the lead time.
Findings: This study finds that facing lead time ambiguity, the manager becomes more conservative when choosing the optimal stock level to hold and the amount of safety stock.
Research limitations/implications: The future research would consider a risk-averse manager who could be compensated or punished as a result of stock management. Then the future research would examine the interactive effects of the manager’s risk aversion and lead time ambiguity on the optimal safety stock level.
Originality/value: This would be the first study that investigates the effects of ambiguity on the level of safety stock.
Exploring the roles of multidimensional versus unidimensional construct of destination social responsibility in explaining destination trust and relationship continuity
Authors:   People&Global Business Association, Han Ju Hyoung , Kim Youngsoo , Jung Minhee
Published: November 2022

Purpose: The purpose of this study is to explore the roles of tourists’ perceived destination social responsibility (DSR) in predicting destination trust and relationship continuity by utilizing multidimensional versus unidimensional construct of DSR.
Design/methodology/approach: This study develops the two-stage model; a first-stage model includes multidimensional constructs of DSR, and a second-stage model includes an integrated construct of unidimensional DSR. Modern cultural heritage tourism destinations in Korea were selected for this study context. In order to test and compare the results of the two models, partial least squares structural equation modeling (PLS-SEM) was applied with 385 online survey responses.
Findings: The results showed that trust plays a significant role in mediating the relationship between DSR and relationship continuity in the both models. However, the effect of DSR becomes differentiated depending on multi- dimensional versus unidimensional construct of DSR.
Research limitations/implications: Theoretical and practical implications, and research limitations with future re search directions are suggested.
Originality/value: This study compares dimensional structure of DSR in predicting destination trust and relationship continuity in a context of modern cultural heritage tourism destination.

The American workforce gives little credibility to creative economy jobs. This research seeks to explore the hesitancy for pursuing creative vocations as a financially stable career amid the capitalist principles emphasized in American public schools. The research uses a lens of racial capitalism to evaluate American schools and economics; artists of identities underrepresented in creative fields were prioritized. Ten individuals working professionally in a creative field answered questions about their economic upbringings, their parent/guardians' view of the arts, their first remembered arts experiences, and reflected on how well equipped their schools were to support the arts. Overall, participants reported early arts exposure influencing the trajectory of their careers. The participants from self-described middle-class families felt more comfortable pursuing their arts careers and noted familial or financial support to fall back on; the interviewees without this safety net reported taking fewer risks in their careers. Economic class proved to be an equal or larger barrier to participant's financial stability in the arts than all other factors. Almost unanimously the participants cited no support from their school counselors and career services regarding arts after high school. Likewise, interviewees shared anecdotes of gawking, irreverence, and disrespect from family, strangers, and peers about their arts career. These findings hold insight about arts educational policy, early childhood development, and intersections of race, culture, class, and labor.
Managing Immersive Theatre in a Post-COVID World

Immersive theatre provides an escape from real life for audiences and an outlet to consume art actively rather than passively (Turnbull 2016). Immersive theatre has floated in and out of relevance since its first appearance in the theatre world in the 1970s and has taken on many different forms over the years. From murder mysteries to Renaissance Faires, immersive theatre is a form of theatre that demands social, and sometimes physical, contact. So how, in the time of social distancing and COVID-19, can immersive theatre stay relevant? How can we as cultural leaders continue to provide our patrons with a unique experience that is still safe? Over the past two years, the theatre industry has scrambled to make safe content for audiences. Open-air theatres have been built, temperature checks and vaccine requirements have arisen, and innovations in technology have all made theatre possible. Holding immersive events outdoors or in an open air space, requiring temperature checks or vaccinations, or holding interactive events via ZOOM are all ways immersive theatre can be made possible while keeping patrons safe.
