Published: October 2024

Цифровая трансформация оказывает влияние как на профессиональную сферу деятельности, так и на сферу образования, где возникает необходимость не только внедрения новых образовательных технологий, но и пересмотра существующих. Цифровые навыки и компетенции становятся значимыми требованиями при трудоустройстве, а своевременность их освоения напрямую пересекается с образовательными процессами в высшей школе. Данное исследование ставит целью изучить восприятие студентами регионального вуза уровня своих цифровых навыков и компетенций, а также проанализировать, чего на сегодняшний день не хватает студентам для соответствия образовательного процесса цифровой повестке. По результатам онлайн-опроса составлен список рекомендаций и замечаний, которые могут быть использованы для практических улучшений образовательной среды.
Digital transformation has an impact on both the professional sphere and the educational sphere, where there is a need not only to introduce new educational technologies, but also to revise existing ones. Digital skills and competencies are becoming significant requirements for employment, and the timeliness of their development directly intersects with educational processes in higher education. This study aims to consider the perception of students at a regional university about the level of their digital skills and competencies, as well as to analyze what students currently lack to comply with the educational process of the digital agenda. Based on the results of the online survey, a list of recommendations and comments was compiled that can be used for practical improvements in the educational environment.
Regional variance in alluvial sedimentation and revised stratigraphy of the Klipheuwel Group and Franschhoek Formation
Authors: Raath R.F. , Penn-Clarke C.R. , Kisters A.F.M. 
Published: October 2024

Abstract
The siliciclastic sediments of the Klipheuwel Group mark the transition from Pan-African tectonism and amalgamation of Southwest Gondwana to the shallow marine deposits of the Cape Supergroup in the Western Cape. The rocks are preserved in a number of seemingly isolated depositories and previous studies have mainly focused on selected occurrences. The lack of any integration of regional sedimentological or structural characteristics has, to date, resulted in only tentative stratigraphic correlations and subdivisions of the Klipheuwel Group. Lithological and structural data from the Klipheuwel Group indicate at least two separate depocentres that accommodated the post Pan-African peneplanation of the Saldania Belt and clastic detritus in distinctly different palaeoenvironments. A northern depocentre can be distinguished from a southern depocentre, each characterised by distinct architectural elements and facies associations that reflect topographic and structural controls. The northern depocentre, including Klipheuwel Group occurrences at Eendekuil, Redelinghuys and Elands Bay, show laterally persistent braided fluvial facies associations that developed multi-storey superimposed ‘braided sheet’ deposits. Here, the rocks show gentle dips and thicknesses range from 300 to 450 m. The southern depocentre, including the Klipheuwel and Klapmutskop localities, are characterised by much larger thicknesses (up to &gt;2 000 m), steep dips of the rocks and laterally discontinuous braided fluvial facies associations that developed staggered channelised braided deposits. The lateral continuity of fluvial facies in the northern depocentre reflect sedimentation on a peneplained basement. The larger thickness, steep dips and strongly channelised deposits in the southern facies, in contrast, indicate deposition in actively subsiding half-graben structures that reactivated basement faults. The spatially closely associated Franschhoek Formation shares numerous characteristics with the Klipheuwel Group but preserves Pan-African strains similar to that of the underlying Malmesbury Group, that may indicate its formation as compressional piggyback basins with synorogenic sedimentation.

Published: October 2024

In the past decade, CubeSats have undergone a revolution, moving from university research projects to enabling industry opportunities and government missions. In 2014, the Jet Propulsion Laboratory, California Institute of Technology (JPL/Caltech) initiated a research and technology development effort to advance CubeSat communication capabilities. One of the critical thrusts was the Ka-band parabolic deployable antenna (KaPDA). This antenna started with the ambitious goal of fitting a 42 dB, 0.5 m, 35 GHz antenna in a 1.5U canister. At that time, there had been minimal development in high-gain CubeSat antennas, critical for high-data-rate communications and remote sensing science. A Ka-band high-gain antenna would provide a 10,000 times increase in data communication rates over an X-band patch antenna and a 100 times increase over state-of-the-art S-band parabolic antennas. This paper discusses designing, building, integrating, and operating the flight antenna from a mechanical perspective, its final performance, and lessons learned. KaPDA enabled the RainCube mission, the first Earth Science CubeSat to have an active instrument. RainCube was launched in May 2018, making KaPDA the second deployable parabolic antenna to fly on a CubeSat and the first to operate in Ka-band, enabling follow-on opportunities for high-rate antenna communications and remote sensing science.

Published: October 2024

OBJECTIVES: To (1) summarize pooled prevalence and incidence rates of concussion by type of sport and (2) synthesize the differences in prevalence or incidence rates of concussion by type of sports in terms of sex, age, type of session, and level of competition. DESIGN: An overview of systematic reviews with meta-analysis. LITERATURE SEARCH: CINAHL, Embase, Epistemonikos, PubMed, Scopus, SPORTDiscus, and the Cochrane Library databases were searched. STUDY SELECTION CRITERIA: Systematic reviews with meta-analyses reporting pooled incidence or prevalence of sport-related concussion. DATA SYNTHESIS: AMSTAR 2 was used to assess the methodological quality of reviews. Overlap between reviews was calculated. RESULTS: Ten systematic reviews with meta-analysis were included, all evaluating incidence rates of concussion. There were no meta-analyses of concussion prevalence. Concussions seem to have a higher incidence in rugby, snowboarding, ice hockey, and American football. In reviews that explored sex-based differences across subgroups, there was a higher incidence rate of concussion in baseball-softball, basketball, and soccer in females compared to males. There were no age subgroups analyzed. The incidence of concussions was higher during games compared to practice in American football, ice hockey, rugby, and soccer. Amateur rugby had higher concussion rates compared to professional rugby. CONCLUSIONS: Rugby, snowboarding, ice hockey, and American football had the highest incidence rate of concussion when no other differences (eg, type of session) were considered. However, important methodological flaws were detected, such as the lack of use of the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system and subgroups for specific factors (eg, age groups).

Exploring the repeatability of pulse arrival time in healthy subjects: A test-retest approach
Authors: Jose Annie S. , Srivastav Shival , Mehta Bharati 
Published: October 2024

Objectives:
Vascular ageing is increasingly being recognised as a vital marker of cardiovascular morbidity and mortality. Assessment of vascular stiffness is an important parameter in this context. Pulse arrival time (PAT) assessed using photoplethysmography (PPG) and digital electrocardiogram (ECG) signals is a feasible and cost-effective parameter for this assessment. However, there are few, if any, studies that have assessed the test-retest repeatability of this parameter over time.

Materials and Methods:
We computed PAT using finger PPG and Lead II ECG and measured it sequentially at five instances over a period of 1 month in 21 healthy adults (10 males and 11 females). Mean and diastolic blood pressure (MBP and DBP) and heart rate (HR) were also measured at each visit. A novel parameter, PAT normalised for HR of 75 (PAT-75), was also computed. PAT and PAT-75 were compared for these visits using repeated measures analysis of variance. The intraclass correlation coefficient (ICC) was used to assess the test-retest reliability of this parameter.

Results:
MBP, DBP, and PAT values did not show any difference between the visits. HR was significantly different between the visits. PAT-75 was significantly lower for the afternoon of day 1 as compared to the forenoon. ICC demonstrated only moderate reliability of PAT (ICC = 0.57), with further reduction observed for PAT-75 (ICC = 0.38).

Conclusion:
PAT was only moderately repeatable on repeated evaluation over a 1-month period. This finding may have implications for the large-scale applicability of this technology, and therefore, we propose further investigation into the repeatability of this parameter in large cohorts.

Published: October 2024

Background Previous research has demonstrated the benefits of both stabilization and non-stabilization of the scapula during stretching in individuals with posterior shoulder tightness, but limited evidence exists in patients with shoulder pain. Hypothesis/Purpose The aim of this study was to determine the effect of stabilized scapular stretching on patients with shoulder pain. The primary hypothesis of this study is that stabilized scapular stretching will improve glenohumeral motion and pain compared to non-stabilized stretch program. A secondary hypothesis of this study is that stabilized scapular stretching will produce greater improvement in function compared to the non-stabilized stretching program. Study Design Randomized Clinical Trial Methods Sixteen patients with sub-acromial pain associated with tendinopathy and associated pathologies presenting to physical therapy were randomized into two groups (stabilized or non-stabilized scapular stretching). Baseline pain and range of motion were measured prior to and following each treatment session for three visits that occurred over the course five to seventeen days depending on the patients availability. The dependent measurements were stabilized horizontal adduction, stabilized internal rotation, stabilized shoulder flexion, non-stabilized shoulder flexion, and current pain level. Results Patients in the scapular stabilization stretching group increased horizontal adduction 40° (CI95 31, 48°) compared to the non-stabilization stretching group increase of 8° (CI95 0, 17°) over the course of the three treatments (p<0.001). Similarly, the stabilized stretching group increased internal rotation 48° (CI95 26, 69°) compared to the non-stabilized stretching group increase of 26° (CI95 4, 48°) (p=0.001). Pain decreased in the stabilized stretching group by 1.4 points (CI95 -0.4, 3.2) but increased slightly in non-stabilized group by -0.5 points (CI95 -2.3, 1.3) which was not a clinically meaningful change. (p=0.03) Conclusion Stabilized scapular stretching was more effective than non-stabilized stretching at gaining shoulder mobility in patients with shoulder pain. Benefits were immediate and sustained between treatment sessions. Stretching interventions improved range of motion but had limited effect on shoulder pain. Level of Evidence 2

Published: October 2024

Background/Purpose The COVID-19 pandemic has impacted adolescents across multiple areas of health. While many factors influence outcomes following anterior cruciate ligament reconstruction (ACLR), the impact of the COVID-19 pandemic on early patient outcomes after ACLR is currently unknown in an adolescent population. The purpose of this study was to determine if short-term clinical outcomes were different in adolescents after ACLR for those who underwent surgery pre-COVID versus during the COVID-19 pandemic timeframe. Design Retrospective cohort Methods A retrospective review of records occurred for patients who underwent ACLR with a quadriceps tendon autograft. Two separate review timeframes were defined according to date of surgery (control: September 2017 - October 2019; COVID: March 2020 - May 2021). Patients were classified into pre-COVID (control) and COVID groups by surgical date and were then age- and sex-matched. Three-month postoperative outcomes were included for analysis, including normalized isometric quadriceps and hamstring peak torque, Anterior Cruciate Ligament – Return to Sport after Injury (ACL-RSI), and the Pedi International Knee Documentation Committee Form (Pedi-IKDC) scores. Results Sixty patients met the inclusion criteria (34 females, 56.7%). Follow-up testing occurred at 3.2 months (98.13 ± 14.91 days) postoperative. A significant difference was found between groups for normalized quadriceps peak torque on the uninvolved limb, with the control group (2.03 ± 0.47 Nm/kg) demonstrating decreased peak torque compared to the COVID group (2.49 ± 0.61 Nm/kg) (p =0.002, effect size (d) = 0.84). For the involved limb, no difference in normalized quadriceps peak torque was observed between the control group (1.25 ± 0.33 Nm/kg) and those who underwent surgery during the COVID-19 pandemic (1.49 ± 0.70 Nm/kg) (p = 0.09). No differences were identified between groups for any of the other strength outcomes (p = 0.31 – 0.87). Similarly, no differences in patient reported outcomes were found for Pedi-IKDC or ACL-RSI between groups (p = 0.12 – 0.43). Conclusion At roughly three months after ACLR, normalized quadriceps peak torque on the uninvolved limb was reduced by 18.5% for adolescents who underwent surgery pre-COVID versus during the COVID-19 pandemic timeframe. No group differences were observed for other isometric strength outcomes, Pedi-IKDC, or ACL-RSI scores.
Resident Case Series: Blood Flow Restriction as an Adjunct to Strengthening Exercises in Two Patients with Subacromial Impingement and High Irritability
Authors: Ceballos Angel , Zeppieri Giorgio , Bialosky Joel 
Published: October 2024

Introduction Evidence informed management of individuals presenting with subacromial impingement syndrome (SAIS) includes strengthening exercises directed at the shoulder musculature. Patients with subacromial impingement syndrome (SAIS) can present with pain during and after completion of heavy resistance training limiting the applicability of this recommended treatment approach. Blood flow restriction (BFR) training is indicated for patients who have pain while completing heavy resistance training and may represent an important treatment modification for patients with SAIS unable to fully participate in a strengthening exercise program. The purpose of this case series is to describe the inclusion of BFR in the treatment of two patients with SAIS. Case descriptions Two middle aged, non-operative patients with signs and symptoms consistent with SAIS and high levels of irritability were included. Treatment over one month consisted of three commonly used exercises in the treatment of SAIS in conjunction with a standard BFR protocol: 75 reps broken up into sets of 30,15,15,15 with the BFR cuff placed over proximal humerus. Outcomes Immediate within session improvements beyond measurement error were observed in resting pain and pain pressure thresholds at three sites. At the end of the course of treatment, clinically meaningful improvements were observed in patient reported outcomes including the PENN Score, ASES score, and the patient-specific functional scale. Clinically meaningful improvements and change beyond measurement error were also observed in range of motion and strength which (assessed via a handheld dynamometer). Discussion The incorporation of low load resistance training with BFR may be a useful adjunct for treating patients with SAIS to promote exercise-induced hypoalgesia, decrease pain, and increase function in the upper extremity.

‘Avoidance Preening’, Displacement Behavior and Co-Dependency in Professional Team Sport: When Wants Become More Important Than Needs
Authors: McLean Blake D. , Strack Donnie S. , Martin David T. 
Published: October 2024

An athlete’s body plays an important role in their performance and well-being. However, game-relevant skills are better determinants of success, compared with physical fitness, in technically-driven team sports. In the professional era, over utilization of resources, in pursuit of physical optimization, can detract from time spent on priorities. Athletes’ non-strategic, time-demanding focus on physical preparation/treatments resembles avian ‘avoidance preening’, whereby stressful situations trigger birds to excessively preen in place of more productive activities. The purpose of this commentary is to explore the behaviors of resource-rich professional teams and the roles of staff dedicated to optimizing physical performance, including circumstances that foster avoidance behavior and create the potential for practitioners to encourage co-dependent relationships with athletes. To cultivate healthy/productive environments, the following is recommended: I) recognition of non-productive avoidance behaviors; II) eschewing unjustified, fear promoting, pathoanatomical language; III) fostering collaborative approaches; IV) encouraging utilization of psychology services; V) recognizing that optimal physical function and feeling good is rarely the primary goal in professional team sports.

Published: October 2024

Deep learning technologies have revolutionized the management of energy, energy consumption, and data security within smart grids through non-intrusive load monitoring (NILM). This paper explores the use of deep learning for real-time intrusion detection in power grids with a primary focus on safeguarding the integrity and security of Data Processing Units (DPUs). An evaluation of various machine learning models, including Support Vector Machine (SVM), Linear Discriminant Analysis (LDA), Decision Trees, and Random Forests, is conducted to detect various types of intrusions, including Fault, Injection, Masquerade, Normal, and Replay. Random Forest produced AUC values of 1.00 for all classes and an overall F1-score of 0.99 for all classes. The Decision Tree model also shows robust performance for detecting Fault and Injection intrusions (AUC = 0.98), with an overall F1-score of 0.94. However, the LDA and SVM models do not perform well in detecting Injection intrusions with overall F1-scores of 0.83 and 0.86. Advances in machine learning can be used to improve smart grid security, reliability, and efficiency, according to this study. These findings highlight the potential of advanced machine learning techniques to enhance smart grid reliability and efficiency. Doi: 10.28991/HIJ-2024-05-03-018 Full Text: PDF

Salah satu perangkat proteksi yang dipasang pada transformator daya adalah rele diferensial. Rele diferensial berfungsi sebagai pengaman pada transformator yang bertujuan untuk mencegah kegagalan proteksi dan meningkatkan kualitas operasional dari sistem transmisi. Pada penelitian ini menggunakan data di Gardu Induk Langsa, data tersebut dihitung secara matematis untuk menetukan rasio current transformer, error mismatch, dan parameter-parameter rele diferensial saat kondisi normal dan saat kondisi gangguan. Rasio CT yang terpasang pada trafo di sisi tegangan primer 150 kV adalah 300:1 A, sementara pada sisi tegangan sekunder 20 kV adalah 2000:1 A. Pemilihan rasio tersebut didasarkan pada perhitungan arus rating, yaitu 254,034 A untuk sisi tegangan primer 150 kV dan 1905,256 A untuk sisi tegangan sekunder 20 kV. Hasil dari simulasi rele diferensial yaitu rele diferensial dapat bekerja apabila arus diferensial lebih besar dari arus setting maka rele diferensial akan bekerja secara optimal dengan memerintahkan Circuit Breaker (CB) untuk trip. Arus setting yang didapat dari hasil perhitungan yaitu 0,1159 A dari 0,3 A yang diset pada rele dan diharapkan dengan setting tersebut sistem proteksi transformator dapat bekerja dengan optimal.
Linguistic discourse analysis of lexico-grammatical features of moves in the research abstracts of medical students in a Ghanaian university
Authors: Fiadzomor Peace , Sebolai Kabelo , Fredericks Brenton Grant 
Published: October 2024

Writing a quality research abstract is crucial for a scholarly report. An abstract should be information and lexically dense, formal, and have a professional tone. This requires precision, objectivity, logicality, technicality, and comprehensiveness. However, writing a good-quality research abstract is a hurdle for novice and inexperienced undergraduate students who study English as a Second Language (ESL), that is English language learners worldwide. This article interrogates the research abstracts written by undergraduate medical students who also studied English Language at the University of Health and Allied Sciences (UHAS) in Ho, Ghana. A qualitative-quantitative approach, guided by Hyland’s (2000, 2004) five-move model, was used to analyze the lexico-grammatical features in the rhetorical moves of the research abstracts written by these students. A corpus of 23 extracts representing a quota of sample tenses, hedges, boosters, and nominalization were analyzed. The data were coded manually and presented as frequency counts and percentages in tables and graphically. The results revealed that rhetorical moves in the research abstracts written by undergraduate medical students of UHAS in Ho, Ghana were replete with simple past, simple present, and perfect tenses, and lexico-grammatical devices such as hedges, boosters, and nominalization to a greater or lesser extent. The study concludes that the research abstracts written by undergraduate medical students of UHAS follow Hyland’s (2002, 2004) five rhetorical move model, and are constituted by specific lexico-grammatical features. The pedagogical implications are discussed, and suggestions for future research are provided.
