Published: August 2022

An accurate estimation of the Thermospheric Neutral Density (TND) is important for predicting the orbit of satellites and objects, for example, those with the altitude of less than 1000 km. Models are often used to simulate TNDs but their accuracy is limited due to modelling restrictions and sensitivity to the calibration period. Satellite missions such as CHAMP, GRACE, GOCE, Swarm, and GRACE-FO are equipped with on-board accelerometer sensors to measure drag forces, which can be used to estimate along-track TNDs. However, spatial and temporal coverage of these space borne TNDs is restricted to the mission design. To make the best use of the modelling tools and measurements, we applied these along-track TND measurements within the sequential Calibration and Data Assimilation (C/DA) framework proposed by (Forootan et al., 2022, doi:10.1038/s41598-022-05952-y). The C/DA is used to re-calibrate the NRLMSISE00 model, which is called “C/DA-NRLMSISE00”, whose outputs fit well to the introduced space-borne TNDs. The C/DA-NRLMSISE00 is applicable for forecasting TNDs and individual neutral mass compositions at any predefined vertical level (between ~100 and ~600 km) with user-defined spatial-temporal sampling. Nine time periods (October 2003, July 2004, March 2008, April 2010, March 2015, September 2017, August 2018, September 2020 and October 2021) associated with space weather storms are selected for our investigations because most of the available models lack accuracy to provide reasonable TND simulations. Independent comparisons are performed with the space-borne TNDs that were not used within the C/DA framework, as well as with the outputs of other thermospheric models such as Jacchia-Bowman 2008 (JB2008) and the High Accuracy Satellite Drag Model (HASDM) database. The numerical results indicate improvements in the Root Mean Squared Errors (RMSE) of the C/DA-NRLMSISE00's TND forecasts compared to NRLMSISE-00, JB2008 and HASDM along-track of the LEO missions. The percentage reductions are found to be: 51%, 8% and 8 % along GRACE (2003, average altitude 490 km), 25%, 20% and 48% along GOCE (2010, average altitude 270 km), 46%, 37% and 35% along Swarm B (2015, average altitude 520 km), 54%, 12% and 5 % along Swarm B (2017, average altitude 514 km), and 41% and 64% along GRACE (FO) (2021, average altitude 504 km), respectively.

Published: August 2022

La percepción de inseguridad es un problema social que impacta negativamente en la convivencia ciudadana, pues reduce la calidad de vida de las personas y modifica su comportamiento, en lo que a uso de espacios públicos se refiere. Esta investigación se desarrolló en el polígono La joya, Reynosa (Tamaulipas - México) Para esto, se analizó la correlación entre espacios públicos deteriorados con percepción de inseguridad. Los resultados muestran una correlación positiva, no obstante, los niveles de asociación son estadísticamente poco significativos, por tanto, se explica -tangencialmente- la percepción de inseguridad a través de los espacios públicos deteriorados, pero no es determinante en la modificación del comportamiento en torno a dicha problemática.

O artigo analisa diferentes experiências de grupos organizados para à defesa das comunidades nos estados mexicanos de Guerrero e Michoacán, contra a insegurança e conflitos gerados pelo narcotráfico - diante da expansão e diversificação de suas atividades lucrativas. Ressalta que a participação das comunidades na apropriação de sua segurança ocorre em um ambiente social em que a legalidade e a ilegalidade são ambíguas, pois tem se configurado por uma zona cinza, funcional ao contexto de reestruturais econômicas regionais que contribuíram para o aumento da violência. Além disso, o artigo questiona a heterogeneidade dos grupos defensivos armados dessa região, enfatizando a tensa tolerância do Estado diante da manifestação do fenômeno, tentando submetê-los ao modelo de participação cidadã de segurança. Também questiona a relevância e o limite das categorias com as quais foram feitas tentativas para caracterizar os grupos que se organizam para garantir segurança e ordem em ambientes transformados pela violência.
Associativismo estudantil africano no Brasil: diáspora, raça, gênero e luta por reconhecimento
Authors: Langa Ercilio Neves Brandão
Published: August 2022

O artigo analisa a gênese, o desenvolvimento e a atuação de agremiações estudantis africanas em Fortaleza-CE. É fruto de observações etnográficas das reuniões associativas, de entrevistas, conversas informais e anotações no caderno de campo entre 2010 e 2017. No quadro teórico, movimenta-se a teoria de Privação relativa de Ted Gurr e a teoria Crítica a partir da noção de luta por reconhecimento de Axel Honneth. As associações estudantis são resultado dos processos de mobilidade estudantil internacional de África para o Brasil, criadas para a defesa e promoção de direitos de alunos africanos de universidades públicas e faculdades privadas na cidade. Com caráter nacional ou plurinacional, as coletividades constituíram brecha para africanos se organizarem em grupos de representação e pressão pois, a condição de estrangeiros os impedia participar politicamente na sociedade brasileira. Elas buscam descontruir imagens de África como lugar de guerras, secas, fomes e pobreza, apresentando visão essencialista, racial e biológica da identidade africana em oposição ao mundo branco, ocidental europeu e capitalista. Contudo, são vulneráveis à conjuntura política interna e externa brasileiras. Por outro lado, constituem espaço de disputas, conflitos pessoais e clivagens políticas, mas também de luta por hegemonia e poder de representar os africanos na cidade.

Published: August 2022

Fixed flexion deformity also called flexion contracture is relatively rare, but a very demanding functional limitation that both surgeons and patients may have to deal with. The purpose of the present study was to evaluate the functional outcomes after posteromedial capsular release in case of fixed flexed deformity > 15 o . Between June 2011 and November 2018, 15 patients (6 males and 9 females) were treated with open posterior capsular release through medial approach for fixed flexion deformity of the knee > 15 o and prospectively followed with a minimum follow-up of 2 years. Primary outcome was knee extension measured with a manual goniometer and secondary outcome treatment related complications. All patients reported inability to walk and clinical semiology of pain and swelling. The mean age of the study population at surgery was 61.7 years with a mean BMI of 30.9 kg/m2. Complete data were recorded for all patients. Statistically significant improvement was found in clinical and functional assessment tools analyzed from baseline to the latest follow-up (p<0.05). More precisely, the mean postoperative fixed flexion deformity was decreased from 23.57 o to 2.86 o . No adverse effect or major complications were recorded during follow-up.

Posterior open release via posteromedial was shown to be an efficient and safe salvage procedure to deal with persistent fixed flexion deformity of more than 15 o following TKA at two years follow-up. However, future studies with a higher number of participants and longer follow-up should be conducted to validate our data.

Published: August 2022

COVID-19 has now alarmed the whole world, putting many countries’ health systems in trouble. We aimed to evaluate the affect of the new treatment strategy that shortens hospital stay in orthopedic trauma patients in pandemic.Trauma patients who underwent surgical treatment between March 15th-May 1st 2019 and 2020 were examined about time interval from admission to surgery, period from surgery to discharge and total hospital stay time. This cohort was compared to a retrospective cohort of patients admitted for the same reasons in the same period of the previous year. During COVID pandemia, 51 trauma patients operated with the mean period from admission to operation 1.45 days, faster than the previous year’s same period (3.76 days). From operation day to discharge time was 1.6 days in pandemic period and 4.3 days last year. The total hospitalization period (3,05 days) was significantly shorter in pandemic than the same period of the last year (8,06 days). (p<0.05). No complications and mortality were observed in any of our patients with faster trauma treatment strategy in pandemic. The operation of orthopedic trauma patients requiring surgery during a pandemic in a shorter time than normal time will not increase the complication and mortality, but will also help to use the bed more effectively by reducing the hospital stay.
Instability after reverse total shoulder arthroplasty: risk factors and how to avoid them

Published: August 2022

Instability after RTSA (4’7%) remains a complication with limited salvage options... or not? We conducted a study of the incidence, predisposing factors, and treatment of RTSA instability to risk stratify patient and identify the most reliable treatment methods.

We retrospectively searched for RTSAs performed between 2008 and 2017 at our institution by one surgeon using the same technique. We identified post- operative dislocations or symptoms of instability. 103 patients underwent 103 RTSAs (97 primary, 6 revision). 6 patients had 5 dislocations (3 in primary RTSAs, 3 in revision RTSAs). Mean time from surgery to diagnosis was 32.6 days (range, 10-60 days). One dislocation occurred immediately after surgery, 0 after falls, 3 from low-energy mechanisms of injury, and 2 without known inciting events.

All dislocations were treated in the operating room; no dislocation was successfully treated with simple closed reduction in the clinic. Although dislocation after RTSA is uncommon, the risk is higher for patients with higher BMI and for patients undergoing revision surgery.

The highest risk of instability occurs in RTSAs done for severe proximal humerus fracture; where the anatomy of the shoulder is changed. In these cases, approximately one in four patients will have a recurrent dislocation. In patients with persistent instability or with risk factors for instability, consideration should be given for use of larger glenospheres and increasing the lateral offset at the time of RTSA. Besides, peri- glenoid release, the suitable tension of the soft tissues tend to be the key of the stability.
The effect of transitional vertebrae and spina bifida occulta on disc herniation, disc degeneration, and end-plate changes in pediatric patients with low back pain
Authors: Illeez Ozge Gulsum , Bahadir Ulger Fatma Esra , Aktas Ilknur
Published: August 2022

The aim of the study is to investigate the assumption whether lumbosacral transitional vertebrae (LSTV) and spina bifida occulta (SBO) cause lumbar disc herniation (LDH), intervertebral disc degeneration (IDD), and vertebral endplate changes / Modic changes (MCs) in children and adolescents with low back pain (LBP). Four hundred patients (aged 10-17) with LBP persisting for at least six weeks were included in the study. Lumbosacral X-rays were examined for the presence of LSTV and SBO. The prevalence of IDD/MCs and LDH at L4-5 and L5-S1 levels were investigated by evaluating the lumbosacral MRI of the patients with and without LSTV-SBO. The study population consisted of 219 girls and 181 boys with mean age 14.9±1.9. LSTV was determined in 67 (16.8%) patients and SBO in 62 (15.5%). No significant difference was observed in the prevalence of IDD, MCs, and LDH in patients with and without LSTV/SBO. LSTV and SBO were not observed in approximately 80% of patients without LDH and IDD/MCs. The presence of LSTV and SBO does not appear to represent a risk factor for early degeneration in lumbar spine and LDH in children and adolescents with LBP.
Radial tuberosity anatomy in intramedullar repair of distal biceps tendon ruptures. A radiological study
Authors: Van Melkebeke Laurens , Van Riet Roger , Duerinckx Joris , Caekebeke Pieter
Published: August 2022

The aim of this study was to measure cortex thickness and medullar canal width of the bicipital tuberosity, to evaluate the accessibility of a intramedullar fixation device and the resistance to pullout strengths of the anterior cortex. The final objective was to determine the length of tendon ingrowth size that will be expected when using this surgical technique.

A total of 144 computer tomography images of the proximal radius were used. Bone thickness of the anterior and posterior cortex and medullar canal size were measured. The possible ingrowth of the tendon was measured both for an anatomical and non- anatomical reinsertion. Statistical and concordance analyses of results were performed.

The average width of the medullar canal was 8,7mm proximal, 7,9mm distal and 7,7mm at the tuberosity. The average posterior and anterior cortex measured respectively 2,5mm and 2,9mm proximal, 3,2mm and 3,2mm distal and 2,8mm and 1,9mm at the radial tuberosity. The possible non-anatomical ingrowth was 7,6 mm on average and the possible anatomical ingrowth was 7,6mm on average. The radial tuberosity anatomy can accommodate the new distal biceps fixation device. The anterior cortex on which the new device relies for support has a similar thickness as the posterior cortex used in bicortical fixation devices which may suggest similar resistance to pull-out strengths. The availability for intra-osseous fixation of the tendon stump may avoids tendon gapping. The intra-osseous length for the tendon stump surpassed reported tendon slippage during mobilization and active contraction of the distal biceps tendon.

This study aims to determine the relationship between COVID-19 anxiety and rumination in university students and to examine the contributions of rumination in predicting COVID-19 anxiety. The research group of this study, which was conducted using the descriptive method and the relational scanning model, consisted of 417 students (86.1% female, 13.9% male) studying in different programs at Selçuk University. “COVID-19 Rumination Scale (C-19RS)”, “Coronavirus Anxiety Scale Short Form” and personal information form are data collection tools used in the study. Data collected for the research was analyzed via SPSS 25.00 package program. Correlation analysis was used to determine the relationships between COVID-19 anxiety and rumination scores of university students, while regression analysis was performed to determine the contribution of rumination scores in predicting COVID-19 anxiety scores. As a result of the research, there was a moderately significant positive correlation between the COVID-19 anxiety scores of university students and their rumination scores. Rumination scores of university students were found to be a significant predictor of COVID-19 anxiety scores, explaining 31% of the variance in their COVID-19 anxiety scores. The research findings were discussed in light of the literature

Geleneksek iktisat, insan davranışlarını incelemek ve kaynakların etkin bir şekilde dağılımını sağlamak olduğundan, tüketici kararlarınınım önemi doğrultusunda davranışsal iktisatta yerini ekonomik yazınında almıştır. Bu bağlamda davranışsal iktisat, davranış bilimleri ve mikroekonomi ilkelerini birleştirerek, insan davranışlarını anlamanın teorik ve metodolojik yolunu sunmaktadır. Ekonominin temel varsayımı, bireylerin akılcı, istikrarlı ve çıkarlarını korumasıdır. Rasyonel davranarak mevcut bilgiler ışığında fayda maksimizasyonu amacıyla bireysel karar verme sürecine girmektedir. Davranışsal iktisadın ortaya çıkmasındaki ihtiyaç, geleneksel tüketici karar alma modellerinin tüketici karar ve davranışlarını açıklamada yetersiz olduğudur. Davranışsal iktisat, bireylerin akılcılığının sınırlı olduğunu kabul ederken, ekonomik davranışa uygulanabilecek bir teorik çerçeve sağladığı için, neo-klasik yaklaşımı mutlak olarak reddetmemektedir. Davranışsal iktisat, neo-klasik iktisattaki anormallikleri ve eksiklikleri tanımlamaktadır. Elde edilen bulgular, bireylerin, neo-klasik kar maksimizasyon amaçlarının rasyonel tercihleri göz ardı edebileceğini, ancak bunun yerine günlük karar verme sürecinde sezgisel yöntemlerden yararlanacaklarını göstermiştir

Bireylerin rasyonel olduğu, sınırsız iradeye sahip olması ve bencil davranması ekonomik sistemin içine girildiğinde farklı standart olmayan tercihlere dönüşebilmektedir. Davranışsal ekonomi, insanların genel olarak ekonomik kararları nasıl aldıklarını anlamak için psikolojik bilimi kullanan bir araştırma alanıdır. Özellikle deneysel araştırmalar bireylerin akılcı olmadığını ispatlar niteliktedir ve davranışsal iktisat irrasyonel birey kavramını açıklamaya yönelmiştir. Bireylerin içinde bulundukları psikolojik durum, sosyal etkenler ve çevresel faktörler kararlarını etkilemektedir.

Published: August 2022

The Information and Communications Technologies (ICT) sector provides different connectivity solutions in urban areas. Unfortunately, market players make little effort to ensure connectivity to underserved markets. The analysis of the existing ICT market revealed the possibility of a solution to this problem by utilizing the latest advances in satellite communication. It is recognized that connectivity through satellites is generally not a popular option in the United Arab Emirates (UAE), although there are still some underserved markets in the UAE that require better connectivity solutions. In this study, the Technology Acceptance Model (TAM) has been used to assess users’ acceptance in the UAE market to introduce NGSO satellite broadband connectivity. We consider the main two independent variables of the model: perceived usefulness (PU) and perceived ease of use (PEU). Additional two variables had been proposed which significantly affect UAE consumers’ intention to use satellite broadband which are: innovativeness (INN) and satisfaction with current services (SAT). The study results support that PU, PEU, and INN will positively influence the UAE population’s intention to use the service. The hypothesis that PEU will positively affect PU was also supported. The hypothesis that SAT will negatively influence the UAE population’s intention to the service was not supported. Additionally, the study also shows that UAE consumers’ intention to use satellite broadband is unrelated to gender or age group. A set of recommendations were drawn to support the smooth introduction of NGSO satellite broadband service in the UAE.

Published: August 2022

E-wallet usage in transactions during the Covid-19 pandemic is a cashless movement that supports breaking the chain of transmission of the Covid-19 virus. Intention to use E-wallet during the pandemic is high due to the stay-at-home recommendation that was enforced since the beginning of the breakdown of the first case in Indonesia. Several studies on technology acceptance have been carried out and this study presents a research framework by integrating technology acceptance model (TAM) and theory of planned behavior (TPB) to obtain more comprehensive results to increase technology acceptance intentions by adding virus fear and risk perception to the models that have been tested previously, since the research was conducted when the pandemic is ongoing. The results reveal that perceived usefulness, perceived ease of use, and perceived risk have a direct or indirect effects on attitudes toward using and behavioral intention to use, moderating results of fear of covid-19 on attitudes and intentions as well was found to significantly increase behavioral intention to use E-wallet during the Covid-19 pandemic.

One of the most used social media platforms is TikTok, which is widely and increasingly used due to the short-video interactive music. Very few studies about why people prefer to use TikTok applications were carried out. Therefore, the objective of the current research is to examine the effect of perceived usefulness, perceived ease of use, perceived enjoyment, sense of belonging, and user-generated content on the adoption of TikTok application, using the TAM model. Quantitative research has been applied as a methodological approach and was successfully carried out through an online survey, gathering a total of 255 filled surveys to test the applicability of the developed research model. The results show that the user-generated content has the highest significant positive influence on the intention to use TikTok. Followed by the perceived enjoyment, then the sense of belonging, the perceived ease of use, and the perceived usefulness, consequently. Also, results show that the independent variables explain 47.8% of the variance in the intention to use TikTok. Finally, to assure the generalizability of the study results the study recommends conducting further research in different countries and communities.

Various literature shows that digital transformational leadership can encourage knowledge sharing and an organization's absorptive capacity to improve performance. This research investigates whether digital transformational leadership and empowering knowledge-based interaction, as well as the power of absorptive capacity, will be able to maintain digital startup sustainability through the improvement of performance. 144 digital startups that are established in a limited corporation and registered in the Baparekraf (Indonesia Tourism and Creative Economy Agencies) were used as the purposive sampling. Data collection was done through online questionnaires from each startup leader and processed with SmartPLS 3.0. The results of the research findings showed that the higher the degree of digital transformational leadership, the higher the degree of the digital performance of startups that include traction and financial performance, and also increased empowering knowledge-based interaction in the form of encouraging goal-oriented participative involvement, intra-team knowledge exchange, and continuous interactive engagement. Empowering knowledge-based interaction develops an absorption capacity process to produce the performance of digital startup organizations.

This study proposes a Fusion, Feature-Level, Face Recognition System (FFLFRS) that is based on the Multi-Resolution, Singular Value Decomposition (MSVD) fusion technique. Face recognition in the FFLFRS is achieved via four processes: face detection, feature extraction, feature fusion, and face classification. In this system, the most significant face features (that is, the eyes, nose, and mouth) are first detected. Then, local and global features are extracted by the Local Binary Pattern (LBP) and Principal Component Analysis (PCA) extraction approaches. Afterwards, the extracted features are fused by the MSVD method and classified by the Artificial Neural Network (ANN). The proposed FFLFRS was verified on 10,000 face images drawn from the face images database of the Olivetti Research Laboratory (ORL). Face recognition performance of this system was contrasted with levels of performance of three state of the art, fusion-level, face recognition systems (FRSs) depending on the Frequency Partition (FP), Laplacian Pyramid (LP), and Covariance Intersection (CI) fusion methods. Ten-thousand images were employed to test the proposed model and assess its performance, which was evaluated in terms of changes in pose, illumination, and expression, besides low resolution and presence of occlusion. The face recognition results of the proposed FFLFRS are encouraging. This system proved to be effective in dealing with images having challenges to face recognition and it could achieve a recognition accuracy as high as 97.78%.
