Policy responses to the rise of global OTT platforms in Korea
Authors: Kim Min Sung , Kim Seongcheol 
Published: July 2024

Abstract
The outbreak of COVID-19 and subsequent social distancing measures sparked a surge in demand and unprecedented growth opportunities for OTT (over-the-top) services. Despite the need to foster Korea’s domestic media and cultural industry, the Korean government has almost failed to properly operate OTT policies and the opportunity went to global operators. Although Korea’s content competitiveness has advanced to a global level, local OTTs continue to lag Netflix. This is not a concern confined to Korea. This paper identifies the focal actors of Korea’s local OTT platforms, analyzes the developmental phases of the Korean OTT market, and draws policy-related and industrial implications by ascertaining, which factors hinder local OTT services from achieving their desired development, within the context of the actor-network theory. This paper offers a fresh perspective on the policy responses to the rise of global OTT platforms and the downturn of local OTT platforms in Korea.
SME digital transformation and the COVID-19 pandemic: a case study of a hard-hit metropolitan area
Authors: Holl Adelheid , Rama Ruth 
Published: July 2024

Abstract
Cities and regions are facing diverse challenges, and the transformation to a digital economy is a core issue. The coronavirus disease-2019 (COVID-19) pandemic has had widespread impacts on business, and it has heightened the need for digitalization. We analyse if and to what degree the COVID-19 pandemic has accelerated the digital transformation of small and medium-sized enterprises (SMEs) in the metropolitan region of Madrid. Our research strategy is based on a quantitative analysis of survey data at the company level. Our results show that a large share of SMEs invested in digital technologies as a response to the pandemic, but there are also important differences between basic and more advanced digital technologies and between manufacturing and service sector firms. SMEs’ previous knowledge and technological resources and capabilities, as well as their collaboration networks with providers are found to trigger adoption of digital technology. Implications for postpandemic policies are highlighted.

Abstract
European bat lyssavirus 1 (EBLV-1, Lyssavirus hamburg) is predominantly detected in serotine bats (Eptesicus serotinus) and is responsible for the majority of bat rabies cases in mainland Europe. A passive bat rabies surveillance scheme detected the virus in a serotine bat in the UK for the first time in October 2018. As of May 2024, 34 cases have been reported, 20 of which involved contact with an animal and 5 reported human contact. We investigated the emergence of EBLV-1 by undertaking comprehensive sequence analysis and Bayesian phylogenetics, based on complete virus genomes of 33 UK sequences and 108 sequences covering six countries in mainland Europe (1968–2023), including 21 French EBLV-1-positive RNA samples sequenced for this study. Sequence analysis revealed extreme similarity among UK EBLV-1 sequences (99.9%–100%), implying a single source of introduction rather than multiple independent introductions. Bayesian analysis revealed that the UK EBLV-1 sequences shared their most recent common ancestor with an EBLV-1 sequence from a serotine bat detected in Brittany, France, in 2001, with an estimated date of divergence of 1997. Within the UK sequences, the earliest divergence was estimated to occur in 2007. This study provides valuable insights into the molecular epidemiology of an emerging zoonotic pathogen and improved understanding of the risks posed to public and animal health.
Examining the Relationship Between Hearing Health Beliefs and Social Determinants of Health in Black Adults
Authors: Lewis Charity T. , Toman Julia , Sanchez Victoria A. , Corvin Jaime , Arnold Michelle L. 
Published: July 2024

Objectives:
Hearing loss is a highly prevalent condition; however, it is widely under-treated, and Black Americans have been found to have significantly lower rates of hearing aid utilization than other ethnic/racial groups. In this exploratory study, we aimed to identify hearing health beliefs among Black adults, guided by the Health Belief Model, with social determinants of health, and examine individual differences in these perspectives.

Design:
The Hearing Beliefs Questionnaire (HBQ) was administered online to measure constructs of the Health Belief Model among 200 Black adults aged 18 to 75 (M = 39.14, SD = 14.24). Approximately 13% reported hearing difficulty. In addition, 11 social determinants of health questions were included. Participants were recruited from a university otolaryngology clinic and local Black congregations, meeting inclusion criteria of being 18 or older and Black/African American. Mean scores and SDs for HBQ subscales were calculated. Analysis included analysis of variance and t tests to explore relationships with demographic variables and social determinants of health. Multiple regression analyses predicted HBQ subscale scores from sociodemographic variables.

Results:
Mean HBQ subscale scores ranged from 3.88 (SD = 2.28) for Perceived Barriers to 6.76 (SD = 1.93) for Perceived Benefits. Positive correlations were observed between Perceived Severity, Perceived Benefits, and Perceived Self-Efficacy scores and participant educational attainment. Lower economic stability was correlated with poorer scores in Perceived Self-Efficacy, Perceived Severity, and Perceived Benefits. Black adults’ willingness to purchase a hearing aid was heavily influenced by their Perceived Benefit, Perceived Severity, and Perceived Self-Efficacy scores, with lower scores correlating with unwillingness to purchase devices. Higher frequency of racism/discrimination and financial hardship correlated with increased Perceived Barriers scores for accessing hearing healthcare. In addition, hearing health beliefs between participants with self-reported hearing difficulty and those without trouble only exhibited differences in the Perceived Susceptibility subscale, with those experiencing hearing difficulty having higher scores in this subscale; no other distinctions were identified.

Conclusions:
The Health Belief Model, used with social determinants of health, revealed associations, and variations, in the hearing health beliefs held by Black adults. The present investigation reveals heterogeneity within this group and pinpoints individuals at higher risk for untreated hearing loss, stemming from their negative perceptions about hearing healthcare. These beliefs are influenced by demographics and social determinants of health, underscoring areas ripe for intervention.
Osseointegration: A new approach to improve functional performance of prostheses – a systematic review of the literature
Authors: Karimi Mohammad Taghi , Kavyani Mahsa , Mehrvar Amir 
Published: July 2024

Background:
Individuals with amputations experience functional limitations in their daily activities, depending on the level of their injuries. They often encounter problems with socket-based prostheses. Osseointegration is a new method in prosthetic rehabilitation that aims to enhance the performance of amputees and reduce the issues associated with current prostheses. The objective of this review was to assess the advantages and disadvantages of this novel approach in the rehabilitation of amputees.

Method:
A search was conducted in various databases, including Google Scholar, PubMed, ISI Web of Knowledge, Embase, and Scopus. The search terms used were “osseointegration,” “prosthesis,” and “amputation.” The quality of the studies was evaluated using the Down and Black tool.

Results:
The search using the aforementioned keywords yielded 18 papers. Out of these, 10 papers focused on the use of osseointegration for lower limb amputations, while 5 papers focused on upper limb amputations. Additionally, 3 papers examined the occurrence of stump infections associated with this method. The quality of the studies ranged from 15 to 20.

Conclusion:
Based on the available literature, osseointegration addresses some of the challenges associated with socket-based prostheses. Furthermore, it improves the performance of prostheses. However, there are several issues with this method, including high costs, stump infections, and the need for extensive expertise to insert the implant. Further large-scale studies are necessary to determine the various limitations and advantages of this approach for different levels of amputations.
The Effect of Thrombin-gelatin Matrix Compared With Absorbable Gelatin Sponge on Intraoperative Hemostasis in Unilateral Open-door Laminoplasty
Authors: Huang Chengyi , Chen Zhu , Liu Hao , He Junbo , Shen Yiwei , Wu Tingkui , Wang Beiyu 
Published: July 2024

Study Design.
Prospective, randomized, parallel-controlled trial.

Objective.
The primary aim of this study was to determine whether thrombin-gelatin matrix (TGM) combined with an absorbable gelatin sponge (AGS) could more greatly reduce intraoperative blood loss (IBL) in unilateral open-door laminoplasty than the sole use of an AGS could. The secondary aims were to evaluate the hemostatic efficiency, amount of postoperative bleeding, and safety of the application of TGM combined with an AGS.

Summary of Background Data.
IBL during cervical laminoplasty is substantial and is a proper indication for the application of hemostatic agents. However, we are unaware of any clinical trials on the application of TGM and an AGS in posterior cervical spine surgery.

Methods.
A total of 80 consecutive patients who underwent unilateral open-door laminoplasty were enrolled from September 2020 to March 2022. Patients were randomized into 2 groups, the TGM-AGS group and the AGS group, with 40 patients in each group. The primary outcome was IBL. Other outcomes included the duration of operation, duration of hemostasis, duration of drainage, maximum decrease in hemoglobin (Hb), length of hospital stay, volume of drainage, number of drainage days, occurrence of adverse events, coagulation indicators, and patient-reported outcome measures (PROMs).

Results.
The mean IBL for patients in the TGM-AGS group (75.22 ± 21.83 mL) was significantly lower than that in the AGS group (252.43 ± 57.39 mL) (mean difference = 177.21 mL, 95% confidence interval [CI], 157.88-196.53 mL, t=18.25, P<0.001); the duration of hemostasis, volume of drainage, days of drainage in the TGM group, and maximum decrease in Hb were also significantly less than those in the AGS group (P<0.01).

Conclusion.
The hemostatic efficacy of TGM-AGS is better than that of an AGS alone in IBL. TGM-AGS is also superior to an AGS alone in the evaluation of hemostatic efficiency and postoperative bleeding.
Educational Interventions for Rapid Response Team Members
Authors: Birch Alexander , Varty Maureen 
Published: July 2024

Background
Research continues to be conducted on rapid response systems as patient outcomes associated with rapid response team activations are still not consistently showing benefit. One particular area of focus that is a growing area is the literature regarding training and education for individual team members of the rapid response team.

Objective
The purpose of this narrative review was to describe the current literature regarding educational interventions for rapid response team members.

Methods
This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. To be included in the narrative review, studies needed to be reporting on educational interventional research for rapid response team members of the efferent limb. No studies were excluded based upon study design or publication years.

Results
This narrative review included 6 studies. Four studies assessed outcomes associated with rapid response team members, and 2 of the studies assessed patient outcomes associated with implementing education routinely for rapid response teams. All studies found a positive impact of implementing educational interventions.

Discussion
Our narrative review found that limited research has been conducted in the area of educational interventions for rapid response team members, and of the articles identified, most did not assess patient-associated outcomes. The findings demonstrate that this area of research is in its early stages, and further work is needed to identify what content should be provided in the education and what educational methodologies should be employed, and to continue to assess patient health outcomes associated with educational interventions for rapid response team members.

Published: July 2024

BACKGROUND
Mannitol may be a good excipient for hyaluronic acid (HA) filler.

OBJECTIVE
This study aimed to assess the tolerability and effectiveness of a mannitol-containing HA filler for the improvement of nasolabial folds (NLFs).

PATIENTS AND METHODS
Thirty Middle Eastern participants aged 18 to 65 years with moderate-to-severe NLFs on the Wrinkle Severity Rating Scale (WSRS) received 1 to 2 mL of a HA filler containing mannitol in both NLFs. Wrinkle Severity Rating Scale; volume, depth, and area of NLFs; and ultrasound parameters were measured at baseline, Weeks 2, 12, and 24 after the injection. Adverse events and participants' satisfaction were recorded in all follow-up visits.

RESULTS
Eighty-nine percent, 86%, and 61% of participants showed at least one grade improvement in WSRS, at Weeks 2, 12, and 24, respectively. The area and volume of NLFs significantly decreased compared with baseline (p-value < .01). In severe NLFs, echo density of the dermis significantly increased at Week 2. Participants reported great satisfaction with the treatment, and adverse events were mainly mild and transient. One patient had significant pain during injection, but this resolved without sequelae.

CONCLUSION
The tested mannitol-containing HA filler showed to be effective in Middle Eastern participants. The safety will require a follow-up larger study.

Authors: Mendonça Karoline Tury de , Pascoal Ana Flávia de Souza , Lanza Fernanda de Cordoba , Viñolas Prat Bernat , Morais Rosane Luzia de Souza , Camargos Ana Cristina Resende 
Published: July 2024

Purpose:
To create a multicriteria index with clinical factors associated with abnormal general movements (GMs) trajectories during a stay in the neonatal intensive care unit.

Methods:
A longitudinal study assessed abnormal GMs trajectories in preterm infants in the neonatal intensive care unit. The multicriteria index included clinical factors such as intraventricular hemorrhage, respiratory support, gestational age, patent ductus arteriosus, and infection based on multi-attribute utility theory.

Results:
A total of 52 preterm newborns, 57.7% male, were evaluated. The multicriteria index correlated with abnormal GMs trajectories and explained 26.5% of the variance in these trajectories.

Conclusion:
The developed multicriteria index, with the inclusion of combined clinical factors, allowed the identification of part of the abnormal trajectories of GMs in preterm infants. The multicriteria analysis can help clinicians to identify infants who have a greater chance of poor developmental trajectories before hospital discharge.

Authors: Rau Nicole M. , Monagle Lisa J. , Fischer Ashley M. 
Published: July 2024

Introduction:
Osteopenia of prematurity is common in the neonatal intensive care unit, with an incidence of up to 54% in extremely low birthweight infants. The baseline fracture rate in our level IV midwestern neonatal intensive care unit was 13%, with poor compliance with recommended intakes of calcium, calcium:phosphorus ratio, and Vitamin D.

Methods:
A multidisciplinary team implemented a screening guideline through four Plan-Do-Study-Act cycles, which addressed staff education, vitamin D screening, and incorporation of calcitriol. In total, 150 patients born between October 1, 2019 and April 30, 2023 were screened for mineral intakes, laboratory abnormalities, and the development of fractures or osteopenia.

Results:
The incidence of fractures decreased from 13% to 5.3%. Compliance with mineral intakes improved for calcium, calcium: phosphorus ratio, and Vitamin D. Infants born after the guideline were 4.8 times less likely to develop fractures.

Conclusion:
Quality improvement methodology successfully decreased the rate of fractures due to osteopenia of prematurity and increased compliance with recommended mineral intakes.

Published: July 2024

Introduction
Research in Saudi Arabia concerning health organizations' readiness to use simulation in healthcare personnel training is insufficient. Therefore, this study explored simulation readiness culture and identified associations between simulation readiness culture and healthcare personnel characteristics at a medical city in the western region of Saudi Arabia.

Methods
This cross-sectional study used convenience sampling and the Simulation Culture Organizational Readiness Survey (SCORS), a 36-item questionnaire, to collect data from healthcare personnel working at 3 hospitals and 5 primary care centers at a medical city in the western region of Saudi Arabia. A total of 209 healthcare personnel participated in the study.

Results
The mean total SCORS score was 120.53 (standard deviation ±28.32). Men had significantly higher Readiness for Culture Change and Time, Personnel, and Resource Readiness subscale scores, as well as SCORS total score. Participants with undergraduate degrees had significantly higher Defined Need and Support for Change subscale scores. In the multiple regression analysis, sex and being certified in simulation statistically significantly predicted the SCORS total score and Readiness for Culture Change subscale score, whereas being certified in simulation alone only statistically significantly predicted the Defined Need and Support for Change subscale score.

Conclusions
Simulation culture readiness showed great potential to integrate simulation in healthcare personnel training. The variation in simulation culture readiness based on demographic characteristics warrants further evaluation and consideration by clinical leaders to better optimize the outcomes of healthcare personnel training.
Novel 4D-printed multi-stable metamaterials: programmability of force-displacement behaviour and deformation sequence
Authors: Wan Mengqi , Yu Keqin , Zeng Hao , Khatibi Akbar A. , Yin Meigui , Sun Huiyu 
Published: July 2024

The unique properties of metamaterials are determined by the configuration and spatial arrangement of artificially designed unit structures. However, the configuration and mechanical properties of conventional metamaterials are challenging to reverse and adjust. Based on curved beams, two types of novel three-dimensional (3D) multi-stable metamaterials with reconfigurable deformation and tunable mechanical properties are designed and fabricated using a four-dimensional (4D) printing method. The effects of temperature and curved-beam thickness on the force-displacement curves and multi-stable snapping sequence of the 3D multi-stable metamaterials are investigated by finite-element analysis (FEA) and experiments. In addition, based on the designed four-branch multi-stable metamaterials, three- and six-branched multi-stable structures are designed by changing the number of curved-beam branches. It is shown that, owing to shape memory effects, the 3D multi-stable metamaterials can realize mechanical programmability, and the multi-stable deformation sequence can be precisely regulated by varying the temperature and curved-beam thickness. These 4D-printed multi-stable metamaterials provide valuable contributions to the design of programmable multi-stable metamaterials and their applications in soft robots and intelligent structures.

Design and experimental validation of a finite-size labyrinthine metamaterial for vibro-acoustics: enabling upscaling towards large-scale structures
Authors: Hermann S. , Billon K. , Parlak A. M. , Orlowsky J. , Collet M. , Madeo A. 
Published: July 2024

In this article, we present the design and experimental validation of a labyrinthine metamaterial for vibro-acoustic applications. Based on a two-dimensional unit cell, different designs of finite-size metamaterial specimens in a sandwich configuration including two plates are proposed. The design phase includes an optimization based on Bloch-Floquet analysis with the aims of maximizing the band gap and extruding the specimens in the third dimension while keeping the absorption properties almost unaffected. By manufacturing and experimentally testing finite-sized specimens, we assess their capacity to mitigate vibrations in vibro-impact tests. The experiments confirm a band gap in the low- to mid-frequency range. Numerical models are employed to validate the experiments and to examine additional vibro-acoustic load cases. The metamaterial’s performances are compared with benchmark solutions, usually employed for noise and vibration mitigation, showing a comparable efficacy in the band gap region. To eventually improve the metamaterial’s performance, we optimize its interaction with the air and test different types of connections between the metamaterial and the homogeneous plates. This finally leads to metamaterial samples largely exceeding the benchmark performances in the band gap region and reveals the potential of interfaces for performance optimization of composed structures.

Authors: Failla Giuseppe , Marzani Alessandro , Palermo Antonio , Russillo Andrea Francesco , Colquitt Daniel 
Published: July 2024

The concept of metamaterial recently emerged as a new frontier of scientific research, encompassing physics, materials science and engineering. In a broad sense, a metamaterial indicates an engineered material with exotic properties not found in nature, obtained by appropriate architecture either at macro-scale or at micro-/nano-scales. The architecture of metamaterials can be tailored to open unforeseen opportunities for mechanical and acoustic applications, as demonstrated by an impressive and increasing number of studies. Building on this knowledge, this theme issue aims to gather cutting-edge theoretical, computational and experimental studies on elastic and acoustic metamaterials, with the purpose of offering a wide perspective on recent achievements and future challenges.
