El objetivo de este estudio fue realizar la adaptación de la Escala de Orientaciones Generales de Causalidad, destinada a evaluar la motivación global, para su uso en población universitaria. Los participantes fueron 364 estudiantes de la Universidad de Buenos Aires de entre 18 y 35 años (62.6% mujeres, 37.4% varones; Medad = 22.97, DEedad = 3). Se recolectaron datos con una encuesta de datos sociodemográficos y académicos, la Escala de Motivación Académica y la Escala de Orientaciones Generales de Causalidad. En primer lugar, se efectuó la adaptación conceptual y lingüística a partir de la traducción y del análisis del contenido de los ítems del test. Mediante un análisis factorial exploratorio, utilizando Minimum Rank Factor Analysis (MRFA) como método de extracción, con rotación oblicua Oblimin directo, se halló una estructura de 15 reactivos agrupados en tres factores (Orientación Autónoma, Orientación Controlada, Orientación Impersonal), que explican el 67.7% de la varianza. La consistencia interna estimada con alfas ordinales resultó ser adecuada para las tres orientaciones (α = .71/.81). Asimismo, se aportaron evidencias de validez de criterio con la Escala de Motivación Académica. Por último, un estudio de test-retest determinó la estabilidad temporal de las puntuaciones. Como resultado, se transfiere tecnología de evaluación mediante la adaptación local de una medida de la motivación global con adecuadas propiedades psicométricas y apta para su uso en estudiantes universitarios.

The current stage of distance education development demands enhancement of standards for training of teachers working in that area. Only professional teachers are able to provide quality education for people with different abilities, interests and needs, considering their personal characteristics and specifics of distance education. It is critically important to analyse the experience and professional qualities of teachers involved in distance learning given the uniqueness of the current situation and a high probability of transition to distance education. The study was focused on establishing the actual preparedness level of teachers for distance learning and identifying prerequisites for formation of teachers’ readiness to provide students distance education.
Key words: teacher, readiness, distance education, distance learning technologies, information and communication technologies.

Background:
The optimal treatment of displaced femoral neck fractures in patients 55 to 70 years old remains controversial. The aim of the present study was to assess the effect of closed reduction and internal fixation with cannulated screws (IF) compared with total hip arthroplasty (THA) on hip pain and function, with use of data for outcome measures, complications, and reoperations.

Methods:
This multicenter randomized controlled trial included all patients 55 to 70 years old who presented with a low-energy displaced femoral neck fracture between December 2013 and December 2018. Patients were randomly allocated to undergo either IF or THA. The primary outcome was the Harris Hip Score (HHS) at 12 months postoperatively. Secondary outcomes were the HHS at 4 and 24 months postoperatively, Oxford Hip Score (OHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), health-related quality of life (EQ-5D-3L [EuroQol 5 Dimensions 3 Levels] index score and EQ-VAS [visual analogue scale]), VAS for pain, and VAS for patient satisfaction at 4, 12, and 24 months postoperatively. Complications and reoperations were continuously monitored. The primary analyses were performed according to the intention-to-treat principle.

Results:
A total of 102 patients with a mean (± standard deviation) age of 63.7 ± 4.2 years were allocated to IF (n = 51) or THA (n = 51). The mean difference in the primary outcome, the HHS at 12 months postoperatively (5.3; 95% confidence interval, 0.9 to 9.7; p = 0.017), was below the predefined minimal clinically important difference of 10 points. However, patients who underwent THA had a significantly higher HHS at 4 and 12 months, better OHS at 4 and 12 months, and better HOOS at 4, 12, and 24 months postoperatively. Patients who underwent THA also reported better health-related quality of life at 4 months postoperatively and reported greater satisfaction and less pain at 4 and 12 months postoperatively. A total of 26 patients in the IF group (51%; 95% confidence interval, 37% to 65%) and 2 patients in the THA group (4%; 95% confidence interval, 0.5% to 13%) underwent a major reoperation.

Conclusions:
In this randomized controlled trial, we showed that patients between 55 and 70 years old who underwent THA for a low-energy displaced femoral neck fracture experienced better outcomes than those who underwent closed reduction and internal fixation.

Racial Disparities in the Utilization of Shoulder Arthroplasty in the United States
Authors: Farley Kevin X. , Dawes Alexander M. , Wilson Jacob M. , Toston Roy J. , Hurt John T. , Gottschalk Michael B. , Navarro Ronald A. , Wagner Eric R. 
Published: June 2022

Background:
As the incidence of shoulder arthroplasty rises at exponential rates, race is an important consideration, as racial disparities have been reported in lower-extremity arthroplasty in the United States. Our study sought to examine these disparities.

Methods:
Using the National Inpatient Sample (NIS) database, all anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (RSA) procedures from 2011 to 2017 were analyzed. The patients were divided into the Black, Hispanic, and White groups.

Results:
Overall, 91.4% of the patients undergoing any shoulder arthroplasty procedure were White, 4.75% were Black, and 3.85% were Hispanic. Age and sex-standardized RSA utilization rates (per 100,000) in White patients increased by 139% from 6.94 in 2011 to 16.60 in 2017. The disparity for Black patients, compared with White patients, was 118% in 2011 and 124% in 2017; the disparity for Hispanic patients was 112% in 2011 and 103% in 2017. Similar disparities in aTSA utilization rates were seen; when compared with White patients, there was a 150% disparity in 2011 and a 197% disparity in 2017 for Black patients, and a 169% disparity in 2011 and a 262% disparity in 2017 for Hispanic patients. Finally, Blacks had a higher rate of non-home discharge, longer length of stay, and higher overall costs, while Hispanics had a longer length of stay and higher cost than Whites.

Conclusions:
Despite many efforts to reduce racial disparities in health-care utilization, the chasm in shoulder arthroplasty in the United States appears to be large and widening further. The exponential increase in utilization of shoulder arthroplasty has not been shared equally among races, and the disparities are larger than those reported in lower-extremity arthroplasty.
Registry-Based Randomized Controlled Trials: Conduct, Advantages and Challenges – A Systematic Review.
Authors: Shea Niamh O , Eustace Joseph , Murphy Ellen , Shiely Frances 
Published: June 2022

Abstract
Background: Registry-based Randomized Controlled Trials (rRCTs) have been described as pragmatic studies utilising patient data embedded in large scale registries, to facilitate key clinical trial procedures including recruitment, randomization and the collection of outcome data. While the practice of utilising registries to support the conduct of randomized trials is increasing, the use of the registries within rRCTs is inconsistent. The purpose of this systematic review is to explore the conduct of rRCTs using a patient registry to facilitate trial recruitment and the collection of outcome data and to discuss their advantages and challenges. Methods: A systematic search of the literature was conducted using five databases from inception to June 2020: PubMed, Embase (through Ovid), CINAHL, Scopus, and the Cochrane Controlled Register of Trials (CENTRAL). The search strategy comprised of MESH terms and key words related to rRCTs. Study selection was performed independently by two reviewers. A risk of bias for each study was completed. A narrative synthesis was conducted. Results: A total 47862 titles were screened and 24 rRCTs were included. Eleven rRCTs (45.8%) used more than one registry to facilitate trial conduct. Six rRCTs (25%) randomized participants via a specific randomization module embedded within a registry. Recruitment ranged between 209 to 106,000 participants. Advantages of rRCTs are recruitment efficiency, shorter trial times, cost effectiveness, outcome data completeness, smaller carbon footprint, less participant burden and ability to conduct multiple trials from the same registry. Challenges are: data collection/management, quality assurance issues and the timing of informed consent. Conclusion: Optimising the design of rRCTs is dependent on the capabilities of the registry. New registries should be designed, and existing registries reviewed to enable the conduct of rRCTs. At all times, data management and quality assurance of all registry data should be given key consideration. We suggest the inclusion of the term ‘registry-based’ in the title of all rRCT manuscripts and a clear simple breakdown of the registry-based conduct of the trial in the abstract, to facilitate indexing in the major databases.

Quantum and classical study of prime numbers, prime gaps and their dynamics
Authors: Pal Charli Chinmayee , Mahapatra Prasanta Kumar , Mishra Subodha 
Published: June 2022

Abstract
A wave function constructed from prime counting function is employed to study the properties of primes using quantum dynamics. The prime gaps are calculated from the expectation values of position of prime numbers. In an analogous nonlinear system, the trajectories, associated nodes with their stability condition and the bifurcation dynamics are studied using classical dynamics. It is interesting to note that the Lambert W functions appear in connection to solutions for the fixed points as functions of energy. The derived potential with the divergence also resembles the effective potential a test particle feels near a massive spherical object in General Theory of Relativity. The coordinate time and proper time corresponding to a black hole serendipitously find their analogy in the solution of the nonlinear dynamics representing primes. The stereographic projection obtained from quantum dynamics on unit circle in the (θ, p θ ) phase space of the real numbers present along x-axis in general and prime numbers in particular provides a simple way to calculate a formula for upper bounds on the prime gaps. The estimated prime gaps is found to be significantly better than that of Cramer’s produced values.
Rural Poverty and Energy Choice: New and Global Evidence
Authors: Falco Salvatore Di , Lynam Gary 
Published: June 2022

Abstract
We combined a global micro level dataset that includes 17 different rural Sub Saharan countries with satellite information about precipitation during the growing season to estimate the impact of economic conditions on energy choice. Differently from the existing literature, we aim to causally estimate the impact of household welfare variation on the likelihood of choosing a specific energy source. It is found that, consistent with theory, increases in income do determine an increase in likelihood of using relatively cleaner sources of fuel. We find, however, that this impact is quantitatively very small. Results hold conditional on assets, wealth and a large battery of controls and fixed effects. Policy implications are developed.
Novel ENG metamaterial for Gain enhancement of an off-set fed CPW Concentric circle shaped patch antenna
Authors: A Sujatha Priyadharshini , Arvind C. , Karthikeyan Madurakavi 
Published: June 2022

Abstract
This paper presents a multiband coplanar waveguide (CPW)-fed concentric circle shaped patch antenna for WLAN, LTE-A, 5G Wi-Fi, and X-band applications, which is loaded with metamaterial unit cell. The proposed patch antenna employs arc shaped patch and concentric circle shaped patch achieves ultra-wideband operation. The proposed two layer antenna configuration consists of metamaterial super-substrate. The measured reflection co-efficient (S11) demonstrated three wideband operation ranging from 3.06GHz − 4.72GHz (B.W of 42%), 4.94GHz-6.19GHz (B.W of 22%) and 6.50 GHz − 10.56 GHz (B.W of 47.5%). The metamaterial structure is obtained through the arrangement of the proposed unit cell in 5 × 5 order. The proposed metamaterial structure properties were examined for wave propagation through the material in two major axes directions (x and y-axis). For both axis, the metamaterial exhibits near Zero refractive index for wide range of frequency. The addition of this super-substrate provides significant gain enhancement by 181% when the maximum gain reaches 6.2 dBi at X-band frequency. Since the proposed antenna is more efficient, it might be used for X-band operations such as satellite communication, military, and medical monitoring.
WITHDRAWN: Outcome of Anterior Curciate Ligament Reconstruction with a Large-size Graft versus an Extraarticular Tenodesis; A Comparative study
Authors: El-Azab Hossam , Moursy Mohamed , Mohamed Mohamed Ali , Elsayed Moustafa 
Published: June 2022

Abstract
Introduction: Large number of patients after Anterior Cruciate Ligament (ACL) reconstruction (R) complain of instability, inability to return to the previous level of sports activity and develop ACL graft failure. There are two augmentations to ACL-R to increasec the stability of knee. Those augmentations either a large-size ACL-graft or combination with extraarticular tenodesis (LET). . Patients and Methods: A Prospective Randomized Comparative study included 100 consecutive patients, who underwent ACL-R with Hamstring Tendon Graft. The patients were allocated into two groups (Group A and B) with Randomization; group A received ACL-R with a large ACL-graft diameter (Triple graft) and group B received ACL-R with a double graft combined with lateral extraarticular tenodesis (Modified Lamaire). Each group had fifty patients. Follow-up was for 2 years. They were examined for graft failure, rotatory instability with the pivot shift test and the outcomes were measured with the international knee documentation committee‘s (IKDC) both subjective and objective scores. Results: In group A, graft failure occurred in two (4.1%) patients, the pivot shift test was positive in three (6.5%) patients, the subjective IKDC score was 90.94 points, and the objective IKDC score was normal or nearly normal in 43 (93.4%) patients. In group B, graft failure occurred in one (2.1%) patient, the pivot shift test was positive in one (2.1%) patient, the subjective IKDC score was 91.9 points, and the objective IKDC score was normal or nearly normal in 44 (95.6%) patients. Conclusion: Both large graft-diameter and combination with extra-articular tenodesis decrease ACL-graft failure rates, postoperative rotatory instability, and improve clinical outcome. However, the combination of anterior curciate ligament reconstruction with extra-articular tenodesis was more effective than large-sized grafts for curciate ligament reconstruction. Level of evidence: Level 1; Randomized Comparative study.
Developing a new hydrological drought index and comparing it with meteorological drought indices in Iran's various climates
Authors: Mosaedi Abolfazl , Sarparast Mehdi 
Published: June 2022

Abstract
Drought is a natural phenomenon that can have an impact on many aspects of human life. Drought indices are commonly used to monitor drought levels. In this research, a fundamental change was made on structure of the SPI index and the hydrological effective rainfall was replaced by total precipitation, thus the new hydrological drought index (SPIH) was derived. The SPIH index was used to present the hydrological drought status of Iran's climatic zones over a 63-year period (1955–2018). Furthermore, it was compared to the four other drought indices of SPI, SPEI, RDI, and RDIe in six stations chosen to represent each climatic zone of Iran (coastal wet, mountain, semi-mountain, semi-desert, desert, and coastal desert). In general, changes in the correlation coefficient between all drought indices demonstrate that with decreasing precipitation and rising evapotranspiration, the correlation coefficient declines and the disparity between all the indices becomes more evident. In most climatic zones, with the exception of coastal wet, the correlation between SPI-SPIH is not as strong as the two-way correlation between other indices. The coastal wet regions have the highest correlation between SPI and SPIH (0.98), followed by mountainous (0.93), semi-mountainous (0.92) regions, and desert areas have the lowest (0.61). In general, in arid areas, hydrological drought based on the SPIH index has a low association with meteorological drought based on the SPI, SPEI, RDI, and RDIe indexes. This demonstrates that there are differences between meteorological drought (SPI, SPEI, RDI, and RDIe) and hydrological drought indices (SPIH) in different climates.
A Hybrid Cryptography and End-to-end Security Model for Wireless Sensor Netwoks
Authors: T SAMPRADEEPRAJ , Devi V. Anusuya 
Published: June 2022

Abstract
Wireless Sensor Network (WSN) is an interconnected and infrastructure-less wireless network. It is deployed in many wireless sensors in an ad-hoc manner to monitor the system, physical or environmental conditions. Wireless sensor networks are used to develop the applications in healthcare, agriculture, vehicle network, defense, etc. Due to this network's need to provide proper security techniques to ensure secure communication. The hybrid cryptographic approach is suitable for WSN because it can take care of sensor's challenges like computation power, storage capability and energy. Symmetric-key cryptography is used to track only one key for the encryption and decryption process. So its computation speed is high. An asymmetric key is used to share information in a very secure way. Both can provide more security against attacks in wireless networks. A new two-phase cryptographic technique has been developed in this work that uses both symmetric and asymmetric methods. In the proposed algorithm, advanced encryption standards (AES) and Rivest–Shamir–Adleman (RSA) are used in different phases of the algorithm. Because symmetric key cryptographic techniques provide a high level of security, and asymmetric key cryptography provides easier key management. phase 1 has been developed using the AES algorithm. In phase 2, RSA has been used, and all phases are executed in parallel. The proposed algorithm provides better encryption, decryption and total execution time when compared to the existing algorithms.
