Investigating Bandura’s Processes of Observational Learning Implementations from EFL Faculty Perspective at Umm Al-Qura University English Language Centre
Authors: Rayes Eman T. , Albelaihi Nuha K.
Published: October 2023

The present study attempts to investigate the implementations of Bandura’s processes of observational learning from an EFL faculty perspective at Umm Al-Qura University English Language Centre. As a prominent skill-learning theory in psychology and education, Bandura’s social learning theory introduced elemental cognitive stages known as observational learning processes that are necessary for acquiring any skill. Knowledge of these processes provides EFL/ESL teachers with theoretical principles to facilitate teaching and learning the complex skills of the English language. The study aims to identify the EFL faculty awareness level of Bandura’s observational learning processes and assess the extent to which their teaching practices endorse observational learning. Also, to examine the relationship between EFL faculty awareness and practices. The study participants consisted of (41) EFL faculty members during the academic year 2021-2022. The researchers developed a web-based survey to collect the information and used descriptive statistics for analysis. The findings revealed that the faculty members’ overall awareness and practices levels of Bandura’s observational learning are high. However, the results indicated the existence of a misconception regarding the concept of modeling and observation held by some of the faculty members. Also, results indicated a significant relationship at (0.05) level between EFL faculty awareness and practices suggesting the applicability of Bandura’s observational learning in the EFL context. The study provides substantial insights for EFL/ESL teachers and researchers regarding the importance of observational learning in teaching and developing language skills. The research concludes with the need for raising awareness procedures and suggestions for future research.
Capture to Communicate: Rhetorical Move 1 in the Abstracts of Hard and Soft Science Post-Graduate Dissertations
Authors: Al-Najhi Ahlam , Samaha Hanaa
Published: October 2023

Academic work is usually evaluated by the quality of its abstract which serves as a concise summary of the research findings. Therefore, the study aims to investigate the rhetorical structure of Move1 in the abstracts of post-graduate dissertations from both Hard Science and Soft Science disciplines. The paper intends to answer three main questions: how is Move1 manifested in terms of its text length? What are the most frequently used Sub-Move patterns of Move1? What are the most common lexical collocations used in Move1? To answer these questions, the study uses Santos’ (1996) framework to analyze a corpus of 100 abstracts selected randomly, 50 from Hard Science and 50 from Soft Science. The findings have revealed that Move1 in Soft Science might use more sentences than those in Hard Science. The findings have also shown that both disciplines rely on Sub-Move-A, stating current knowledge, and Sub-Move2, stating the research gap, as essential for communicating their ideas while the other Sub-Moves were rarely used. In terms of lexical collocations, while post-graduates in both disciplines frequently used the Adjective+Noun lexical collocation as their preferred structure to construct M1, the use of the other lexical collocations varied in both disciplines. The study concluded that Move1 is considered obligatory in situating the research, establishing its context, and capturing and communicating findings. Besides the pedagogical implications suggested, the study’s findings hopefully contribute to the development of abstract move-schema theory, enhance scholarly understanding of Move1 characteristics, and guide future research in the field.
Mind and machine: rooting out corrupt politicians
Authors: Robinson Thomas Samuel , Ruiz Nelson A. , Ocantos Ezequiel Gonzalez
Published: October 2023

Despite its consequences, voters keep electing corrupt politicians. One common explanation is that voters simply lack information on whether candidates are corrupt, yet studies that deliberately provide such information find electoral accountability is weak. Can we root out corrupt politicians? We take a novel approach: first, we employ machine learning to identify widely available political/personal characteristics that are predictive of corrupt practices in Colombia. We then design an experiment that varies the provision of these predictors to study if voters discriminate corrupt from non-corrupt politicians. Results indicate that the presence of candidate images, the presence of a large donor, and information on candidates' political experience decreases the likelihood of choosing a corrupt politician. Moreover, voters behave differently according to their understanding of what corruption is and their attitudes towards it. Compared to established findings, using a novel approach, we show it is possible for voters to root-out corrupt politicians.
A Sociopragmatic Study of the Strategies of Ostensible Invitations in Saudi Arabic
Authors: Alzahrani Shorouq Ashoor Dhaifallah
Published: October 2023

The current study investigated the speech act of ostensible invitations in Saudi Arabic from a sociopragmatic perspective. It was conducted to examine whether Saudi Arabic speakers draw on the same strategies stipulated by Clark and Isaacs (1990) for extending ostensible invitations. Additionally, the study aimed at investigating whether there are Saudi-specific strategies for extending ostensible invitations. To this end, the study examined 37 recalled instances of ostensible invitations provided by Saudi Arabic speakers in the Central Region of Saudi Arabia, Riyadh. The corpus of the study was compiled through face-to-face and written interviews with 37 informants aged between 18 to 60. The collected data was analyzed on the basis of Clark and Isaacs’s seven strategies for establishing ostensible invitations. Results showed that Saudi Arabic speakers utilize the seven strategies proposed by Clark and Isaacs for extending ostensible invitations, yet with relative weight. The most frequently used strategies by Saudi Arabic speakers to issue ostensible invitations in the collected exchanges were the absence of persistence, which was detected in (86%) of the exchanges, and the absence of motivating the invitee, which was used in (73%) of the collected ostensible invitations. Those were followed in order of frequency by vague arrangements (59%), implausibility (49%), inappropriate cues (19%), solicitation (14%), and hedging (5%). In addition to Clark and Isaacs’s proposed strategies, the study found that three more strategies are employed by Saudi Arabic speakers to highlight the ostensibility of their invitations which are: using intensifying and empty swearing devices (e.g., d̪ˁaroori, laazem, wallah, etc.) (27%), extending the invitation in the form of a question (5%), and asking someone else to extend the invitation on behalf of the inviter (5%), the last of which seems to be peculiar to Saudi Arabic speakers.

Authors: AlGhafri Mahmood , Mirza Chahrazed , Gabarre Cécile
Published: October 2023

Understanding students’ attitudes toward oral corrective feedback is pivotal. This case study explored English Language Omani students’ attitudes toward teachers’ oral corrective feedback strategies to check the congruence between teachers’ and students’ preferences. We raised the following questions: What types of oral corrective feedback are used by teachers and preferred by students? Observational data were collected from two Omani English teachers to discern the types and frequencies of Oral Corrective Feedback utilized. Additionally, semi-structured interviews with six students were conducted to gain a holistic view of their perspectives and preferences. Classroom observations were quantitatively scrutinized for data analysis, whereas the interview data underwent a grounded theory procedure. The data demonstrated that teachers predominantly employed the ‘recast’ type of feedback. Notably, students showcased a generally positive attitude towards Oral Corrective Feedback. They preferred the ‘repetition’ and ‘elicitation’ feedback types.Moreover, internal factors, like personal motivation and language proficiency, and external factors, such as curriculum challenges and teacher personalities, emerged as significant influencers of their attitudes and choices. The study unearthed an incongruence between students’ preferences and the teachers’ actual Oral Corrective Feedback practices. This incongruence suggests potential impediments to the effectiveness of feedback in facilitating optimal learning experiences. There is a need to bridge the gap between teaching practices and student preferences to improve learning outcomes and feedback.

Published: October 2023

The importance of instructional design competency for university lecturers of English as a Foreign Language in delivering Higher-ordered, Innovative, and Challenging courses within the Golden Curriculum context in China cannot be underestimated. However, research in this area is limited, posing the need for teachers to reskill and upskill themselves to improve their teaching competencies. Therefore, this study aims to develop an instructional design competency framework based on a content analysis of 18 national award-winning instructional designs from the Star Teacher Contest between 2020 and 2022, using NVivo12 software. The framework encompasses four key elements: learning and learners, learning objectives, learning activities, and learning assessment. The findings emphasize the importance of understanding learning theories, employing scaffolding techniques, and catering to learners’ characteristics to support their academic progress. Moreover, the framework highlights the significance of fostering critical thinking and cross-cultural communication competencies, creating challenging yet feasible tasks, and using various assessment tools that incorporate real-life learning outcomes. By using this instructional design competency framework, teachers can enhance their teaching competencies and effectively implement the Golden Curriculum. Furthermore, educational institutions can use the framework to provide targeted support and training to teachers, enabling a successful integration of the Golden Curriculum into their English teaching programs.

Published: October 2023

Mosques and masjids are the most important parts of Islamic culture in terms of their architectural and structural characteristics. These structures also provide an important insight into the construction techniques and historical process of the region in which they were built. Many of these structures are still in use around the world. However, most historical mosques and masjids are vulnerable to earthquakes or are not strong enough. Therefore, it is important to know the risk status of these important structures with respect to earthquake forces and to carry out the necessary strengthening works. In this study, the performance of the historical Ahi Musa Masjid (built in 1185) was investigated using the linear earthquake solution method, which provides a practical approach to determining the earthquake performance of historical structures. Firstly, studies were carried out to determine the geometric and material properties of the historical Masjid. A finite element model of the historical Masjid was then constructed and linear performance analyses were performed under vertical loads and equivalent earthquake loads. As a result of the analyses, the displacement ratios, compressive and shear stresses of the historical Masjid were obtained and evaluated according to the collapse prevention performance level for the earthquake level DD-3, which is one of the performance levels recommended for historical structures of local importance in the Guidelines for the Management of Earthquake Risks for Historical Structures. The aforementioned stress and drift ratio values remained below the reference values. In conclusion, the Masjid will safely withstand the potential effects of an earthquake.
Fragility analysis of a multi-span continuous steel roadway bridge in Türkiye: A case study
Authors: Yılmaz Mehmet Fatih , Aydın Abdulkadir Cüneyt
Published: October 2023

One of the most widely utilized methods for determining seismic performance and allowing additional study is fragility analysis. The fragility curve, which is typically characterized by two-parameter log-normal distribution functions, depicts the probability of bridge components exceeding a certain damage limit. This study examines the fragility analysis of a multi-span continuous (MSC) steel roadway bridge in Türkiye. The probabilistic seismic demand model (PSDMs) is illustrated by conducting many time history analyses (THA). The nonlinear analyses are conducted for sixty earthquakes. Logarithmic regression analyses and fragility curves were derived for varying intensity measures (IM) in terms of efficiency. Monte Carlo analysis was used to derive the system fragility curve of the bridge. The PGA and ASI are the most proper intensity measure for the fragility curve of the bridge. Moreover, the slight damage can be visualized with a higher probability for the small intensity measure that even mild earthquake motion can cause some slight damage on the bridge but after slight damage bridge has further capacity until the collapse damage is visualized.

Authors: Bayrak Barış
Published: October 2023

The SIFCON concrete reinforced with glass-fiber reinforced polymer (GFRP) bars can provide a construction system with high durability and strength. Slurry infiltrated fibrous concrete (SIFCON) is a new type of conventional fiber reinforced concrete. The aim of this paper is to evaluate the flexural and shear behavior of the SIFCON concrete beams reinforced with GFRP bars were evaluated under four-point bending and three-point shear tests. The parameters investigated were material type of longitudinal reinforcement (steel and GFRP), transverse reinforcement type (steel and mesh) and mesh reinforcement spacing (25 mm and 12 mm). For this purpose, a total of twelve SIFCON concrete beams with steel and GFRP bar as longitudinal reinforcement measuring 150x150x800 mm were cast. Moreover, stirrup and mesh reinforcement as transverse reinforcement are another main parameter of this study. The test results showed that the effects of longitudinal and transverse reinforcement type and mesh spacing on the strength, crack propagation, and energy dissipation capacity of RC beams under bending and shear were experimentally investigated. The use of steel longitudinal reinforcement in both four-point and three-point tests increased the bending moment and shear strength compared to beams with GFRP. Moreover, although the use of mesh reinforcement in reinforced concrete beams under four-point bending reduced the strength, it increased the strength in beams with GFRP. In the samples under the shear force, the use of mesh reinforcement in the steel reinforced group increases the shear strength, but the use of mesh reinforcement in the GFRP group decreases the shear strength.

La leptospirose : la zoonose la plus répandue
Authors: Contenti J. , Delta D. , Camous L. , Piednoir P.
Published: October 2023

La leptospirose est une zoonose bactérienne (Leptospira spp. ; bacille à Gram négatif) de répartition mondiale. Son incidence est croissante en France ces dernières années, avoisinant maintenant celle de l'hépatite A (1/100 000). Face à un patient présentant une fièvre en retour de voyage en zone tropicale, le diagnostic de leptospirose doit être évoqué. Mais cette hypothèse diagnostique doit rester envisageable en dehors de tout déplacement, notamment lors des périodes à risque (été-automne), et lors d'activités récréatives avec exposition à l'eau douce (canoë-kayak, baignade, canyoning). La symptomatologie clinique à la phase initiale va mimer un syndrome pseudogrippal, rendant le diagnostic difficile. Le clinicien doit s'efforcer de rechercher les facteurs de risque d'exposition et s'appuyer sur des arguments clinicobiologiques (myalgies, toux, atteinte conjonctivale, thrombopénie, rhabdomyolyse, cholestase) fréquemment associés à la leptospirose. Le but étant la mise en place d'une antibiothérapie précoce avant l'apparition de formes graves ictérohémorragique ou respiratoire, responsables d'une mortalité accrue. Le traitement repose principalement sur l'usage d'antibiotiques (bêtalactamines injectables dans les formes sévères [céphalosporines] ou l'amoxicilline, doxycycline ou l'azithromycine dans les formes non sévères) associés à des soins de support (hydratation, recharge potassique, hémodialyse), pouvant nécessiter une hospitalisation en service de réanimation.

OBJECTIVE

The lateral aspect of the cerebellomesencephalic fissure frequently harbors vascular pathology and is a common surgical corridor used to access the pons tegmentum, as well as the cerebellum and its superior and middle peduncles. The quadrangular lobule of the cerebellum (QLC) represents an obstacle to reach these structures. The authors sought to analyze and compare exposure of the cerebellar interpeduncular region (CIPR) before and after QLC resection and provide a case series to evaluate its clinical applicability.

METHODS

Forty-two sides of human brainstems were prepared with Klingler’s method and dissected. The exposure area before and after resection of the QLC was measured and statistically studied. A case series of 59 patients who underwent QLC resection for the treatment of CIPR lesions was presented and clinical outcomes were evaluated at 1-year follow-up.

RESULTS

The anteroposterior surgical corridor of the CIPR increased by 10.3 mm after resection of the QLC. The mean exposure areas were 42 mm2 before resection of the QLC and 159.6 mm2 after resection. In this series, ataxia, extrapyramidal syndrome, and akinetic mutism were found after surgery. However, all these cases resolved within 1 year of follow-up. Modified Rankin Scale score improved by 1 grade, on average.

CONCLUSIONS

QLC resection significantly increased the exposure area, mainly in the anteroposterior axis. This surgical strategy appears to be safe and may help the neurosurgeon when operating on the lateral aspect of the cerebellomesencephalic fissure.

Published: October 2023

OBJECTIVE

The influence of persistent postoperative hyperglycemia after craniotomy has not yet been explored. This study aimed to investigate the hypothesis that persistent postoperative hyperglycemia is associated with mortality in patients undergoing an elective craniotomy.

METHODS

This study included adult patients (age ≥ 18 years) undergoing an elective craniotomy between January 2011 and March 2021 at the West China Hospital, Sichuan University. Peak daily blood glucose values measured within the first 7 days after craniotomy were collected. Persistent hyperglycemia was defined by two or more consecutive serum glucose levels of mild, moderate, or severe hyperglycemia. Normoglycemia, mild hyperglycemia, moderate hyperglycemia, and severe hyperglycemia were defined as glucose values of ≤ 6.1 mmol/L, > 6.1 and ≤ 7.8 mmol/L, > 7.8 and ≤ 10.0 mmol/L, and > 10.0 mmol/L, respectively.

RESULTS

This study included 14,907 patients undergoing an elective craniotomy. In the multivariable analysis, both moderate (adjusted OR 3.76, 95% CI 2.68–5.27) and severe (adjusted OR 3.82, 95% CI 2.54–5.76) persistent hyperglycemia in patients were associated with higher 30-day mortality compared with normoglycemia. However, this association was not observed in patients with mild hyperglycemia (adjusted OR 1.32, 95% CI 0.93–1.88). Interestingly, this association was observed regardless of whether patients had preoperative hyperglycemia. There was no interaction between moderate or severe hyperglycemia and preexisting diabetes (p for interaction = 0.65). When postoperative peak blood glucose values within the first 7 days after craniotomy were evaluated as a continuous variable, for each 1-mmol/L increase in blood glucose, the adjusted OR of 30-day mortality was 1.17 (95% CI 1.14–1.21). Postoperative blood glucose (area under the curve [AUC] = 0.78) was superior to preoperative blood glucose (AUC = 0.65; p < 0.001) for predicting mortality. Moderate and severe persistent hyperglycemia in patients were associated with an increased risk of deep venous thrombosis (adjusted OR 3.20, 95% CI 2.31–4.42), pneumonia (adjusted OR 2.77, 95% CI 2.40–3.21), myocardial infarction (adjusted OR 4.38, 95% CI 3.41–5.61), and prolonged hospital stays (adjusted OR 1.43, 95% CI 1.29–1.59).

CONCLUSIONS

In patients undergoing an elective craniotomy, moderate and severe persistent postoperative hyperglycemia were associated with an increased risk of mortality compared with normoglycemia, regardless of preoperative hyperglycemia.

Published: October 2023

OBJECTIVE

Antifibrinolytics, such as tranexamic acid (TXA), have been shown to decrease intraoperative blood loss across multiple surgical disciplines. However, they carry the theoretical risk of thromboembolic events secondary to induced hypercoagulability. Therefore, the aim of this study was to systematically review the available literature and perform a meta-analysis on the use of TXA in meningioma resection to assess thromboembolic risks.

METHODS

The PubMed, Web of Science, and Google Scholar databases were reviewed for all randomized controlled trials presenting primary data on TXA use during resection of intracranial meningiomas. Data were gathered on operative duration, venous thromboembolic complications, deep venous thrombosis, use of allogeneic blood transfusion, estimated blood loss (EBL), and postoperative hemoglobin. Patients who received TXA were compared with controls who did not receive TXA intraoperatively using random-effects models.

RESULTS

A total of 508 unique articles were identified, of which 493 underwent full-text review. Ultimately, 6 studies with 381 total patients (190 receiving TXA) were included in the final analysis. All 6 trials were randomized, blinded, and placebo controlled with a TXA administration rate of a 20-mg/kg load followed by a 1-mg/kg/hr infusion. All studies were performed in lower-middle-income countries. There were no reported instances of venous thromboembolism (VTE) in the TXA and non-TXA cohorts. Patients receiving TXA exhibited fewer allogeneic transfusions (21.5% vs 41.6% [OR 0.26, 95% CI 0.09–0.77], p = 0.02) and lower EBL (MD −282.48 mL [95% CI −367.77 to −197.20 mL], p < 0.001) compared with patients who did not receive TXA, and they also had lower rates of perioperative complications (10.7% vs 19.9% [OR 0.47, 95% CI 0.2–0.95], p = 0.04).

CONCLUSIONS

Current literature suggests that TXA is not associated with increased risk for VTE when administered during resection of intracranial meningioma. TXA appears to decrease intraoperative blood loss and allogeneic transfusion requirements during meningioma resection and thus may improve the safety of surgical management of this pathology.

Published: October 2023

Despite the efforts spent in clinical trials in neuro-oncology during the last few decades, many challenges remain in the radiologic evaluation of brain tumors and metastases. This article aims to explain the current use of tumor metrics, especially in phase II clinical trials, to evaluate
response to systemic therapy in neuro-oncology. We will discuss the imaging findings associated with progression and with partial, minor, or complete response to treatment, as well as the method of measurement, the distinction between disease-related and treatment-related changes, and inclusion
of clinical symptoms to define treatment response and progression. The evaluation of response in brain tumors requires metrics that account for differences in response between high- and low-grade gliomas and specific tumor behaviors associated with radiation and immunotherapy, among other
pitfalls. Advanced brain imaging techniques, such as perfusion and permeability imaging, should be incorporated into clinical trials to measure response to novel therapeutic agents more accurately.Learning Objectives: To understand the role of tumor metrics analysis and the main challenges
and pitfalls of applying neuro-oncology imaging criteria

Evaluation of the effectiveness of sliding redundancy of radioelectronic facilities
Authors: Gelfman T. E. , Pirkhavka A. P.
Published: October 2023

Objectives. The increased reliability of radioelectronic facilities can be achieved by the application of structural and load redundancy. Structural redundancy is achieved taking into account multiplicity of redundancy and the intensity of failures of elements of radioelectronic facilities, while load redundancy involves an easing of electrical, thermal, and mechanical operating modes of the elements. The choice of a redundancy method is determined according to reliability indicator requirements, which may often be contradictory. Therefore, the problem of how to effectively combine structural redundancy and load redundancy methods is very topical. In long-life radioelectronic facilities, for example, in satellite communication repeater systems, sliding redundancy is applied when limiting mass-dimensional parameters and consequently consumed energy. The aim of the work is to evaluate the efficiency of sliding redundancy according to various reliability indicators when altering redundancy multiplicity, reserve operating mode, element failure intensity, and switching device type.

Methods. To describe the structure of a complex sliding redundancy system, a logical-probabilistic method is used, in which the dependence of the system reliability indicators on the reliability indicators of the elements is formulated as a logical function of operability. Graph-analytical methods are used to compare different variants of reliability logic schemes.

Results. Mathematical models have been obtained to evaluate the effectiveness of sliding reservation. A comparative analysis of the efficiency of sliding redundancy with a loaded and unloaded reserve was carried out in terms failure-free operation probability, as well as gamma-percentage resource, failure rate when changing the fractional multiplicity of the redundancy, and element failure rate. The influence of the reliability of the switching device on the efficiency of the sliding redundancy is considered.

Conclusions. Practical recommendations on the selection of the redundancy mode are presented according to different reliability indices and constructed mathematical models of the sliding redundancy efficiency coefficients. The correlation between the reliability indices of elements and the switching device whose reliability can be discounted, is determined. To increase the efficiency of sliding redundancy of radioelectronic facilities, it is necessary to combine multiplicity of redundancy and the operating mode of the reserve with approaches aimed at reducing the intensity of failure of elements.
Application of double-error correction codes to protect configuration programmable logic memory against space radiation
Authors: Lepeshkina E. S. , Kustov N. D. , Khanov V. K.
Published: October 2023

Objectives. Programmable logic integrated circuits of the field programmable gate array (FPGA) type based on static configuration memory are widely used in the electronics of onboard spacecraft systems. Under the influence of space radiation, errors may occur in the FPGA configuration memory. The main methods of protection against such errors involve various options for reservation triggers, as well as the use of error-correcting codes in special error detection and correction circuits. The purpose of the present work is to determine which error-correcting codes are best suited to the implementation of internal scrubbing of the FPGA configuration memory taking redundancy into account.

Methods. The paper analyses various methods for scrubbing FPGA configuration memory, which are used to correct errors caused by the action of space radiation. It is proposed to increase the efficiency of internal scrubbing of the FPGA configuration memory using codes that correct both single- and double-adjacent SEC-DED-DAEC errors. In this case, the need to perform external scrubbing of the configuration memory is reduced by overwriting it with a reference configuration from non-volatile radiation-resistant memory; in this way, FPGA downtime caused by the external scrubbing procedure is reduced. Due to the known SEC-DED-DAEC codes having a non-zero probability of erroneous detection and subsequent erroneous correction of a double non-adjacent error, as well as various redundancy and implementation complexities, a study was made of the most efficient code for internal scrubbing.

Results. The results showed that the Datta, Neale and Hoyoon–Yongsurk codes are optimal from the indicated positions. Recommendations are given for selecting a specific code depending on the specific requirements for a particular planned space mission.

Conclusions. The study confirms the effectiveness of protecting the memory of programmable logic by using two-error-correcting codes.
Automatic depersonalization of confidential information
Authors: Babak N G. , Belorybkin L. Yu. , Otsokov S. A. , Terenin A. T. , Shabrova A. I.
Published: October 2023

Objectives. As the scope of personal data transmitted online continues to grow, national legislatures are increasingly regulating the storage and processing of digital information. This paper raises the problem of protecting personal data and other confidential information such as bank secrecy or medical confidentiality of individuals. One approach to the protection of confidential data is to depersonalize it, i.e., to transform it so that it becomes impossible to identify the specific subject to whom the data belongs. The aim of the work is to develop a method for the rapid and safe automation of the depersonalization process using machine learning technologies.

Methods. The authors propose the use of artificial intelligence models to implement a system for the automatic depersonalization of personal data without the use of human labor to preclude the possibility of recognizing confidential information even in unstructured data with sufficient accuracy. Rule-based algorithms for improving the precision of the depersonalization system are described.

Results. In order to solve this problem, a model of named entity recognition is trained on confidential data provided by the authors. In conjunction with rule-based algorithms, an F1 score greater than 0.9 is achieved. For solving specific depersonalization problems, a choice between several implemented anonymization algorithm variants can be made.

Conclusions. The developed system solves the problem of automatic anonymization of confidential data. This opens an opportunity to ensure the secure processing and transmission of confidential information in many areas, such as banking, government administration, and advertising campaigns. The automation of the depersonalization process makes it possible to transfer confidential information in cases where it is necessary, but not currently possible due to legal restrictions. The distinctive feature of the developed solution is that both structured data and unstructured data are depersonalized, including the preservation of context.

Both in the whole sample and in the religious experience subgroups, the main observed characteristics (approximately 70%) were a special Light and Unconditional Love, associated with other characteristics such as Oneness and Nonjudgmental, very similar to the descriptions reported following spiritual and mystical experiences.

Only 13.9% of the descriptions reported God or Jesus assuming human form, as represented in popular religious images.

These characteristics are not commonly reported descriptions of God’s in the texts of the main monotheistic religions.

These first-person accounts of God’s characteristics complement what has been reported in association with spiritual/mystical experiences, offering a great resource for the scientific investigation of God’s nature.
Characteristics of Maxilllofacial Trauma Patiens before and during the Covid-19 Pandemic in Oral and Maxilllofacial Surgery Department of Dr. Hasan Sadikin Hospital Bandung

Published: October 2023

Introduction: Prior to the COVID-19 pandemic, motor vehicle accidents, falls, physical assaults, and sports injuries were the main causes of maxillofacial trauma. The existence of interventions to prevent the COVID-19 pandemic resulted in home-centered social activities in the community. This also contributes to alterations in the aetiology of maxillofacial trauma that occur worldwide and may affect other characteristics of this entity.
Methods:This is a retrospective study conducted at the Hasan Sadikin Hospital, Bandung, West Java, Indonesia, and was carried out in September–December 2022. The population of this study were maxillofacial trauma patients with diagnoses of vulnus (laceratum, schissum, punctum, and morsum), frontal, mandibular, maxillary fractures, orbit, naso-orbito-ethmoid (NOE), zygomaticus, and dentoalveolar fractures before the 2018–2019 pandemic period and during the 2020–2021 pandemic period at the Oral and Maxillofacial Surgery Department at RSUP Dr. Hasan Sadikin Bandung through the emergency department.The variables studied included age, gender, type of trauma, etiology, alcohol involvement, and management.The data are presented as frequency distribution and percentage in tabular and diagram.
Results: During the 2018–2021 periods, there were 504 patients who experienced maxillofacial trauma before the COVID-19 pandemic, and this number has decreased to 216 patients during the COVID-19 pandemic. The majority of maxillofacial trauma experienced both before (n = 314; [62%]) and during (n = 166; [77%]) the COVID-19 pandemic was caused by motor vehicle accidents. Most of patients before the COVID-19 pandemic were aged 0–19 years (n = 230; [46%]), meanwhile, during the COVID-19 pandemic most patients were aged 20–39 years (n = 88; [41%]).Overall, there were no differences in sex characteristics, alcohol involvement, type of maxillofacial trauma, or treatment given before and during the COVID-19 pandemic.
Conclusion: The existence of interventions to prevent the COVID-19 pandemic by imposing Large-Scale Social Restrictions (PSBB) has resulted in modifications to community social activities that are centered in the home. This factor contributed to some differences in the characteristics of maxillofacial trauma patients at the Oral and Maxillofacial Surgery Department in Hasan Sadikin Hospital before and during the COVID-19 pandemic.

We present a case report of a 52-year-old man with a huge (12×11×10 cm) distal radius giant cell tumor (GCT) that is a lytic lesion without calcification with volar and dorsal cortical destruction. We perform the wide resection of the distal radius (and the proximal row of the carp) and ipsilateral ulna translocation (preserving its muscular attachments and osteotomized and excised the distal end of the ulna) to radius position and wrist arthrodesis with a reconstruction plate. The size of the tumor and the choice of its treatment method are challenging. This study shows that extensive resection of the distal radius and ipsilateral ulna translocation to radius position and wrist arthrodesis can be an appropriate treatment for huge distal radius giant cell tumor (GCT).
High-capacity reversible data hiding by recursive look-ahead in encrypted images adaptive MSB prediction for the cloud computing
Authors: Paul J Selwyn , Suchithra R.
Published: October 2023

The present research proposes a high-capacity reversible data embedding technique (RDH-EI) for applications utilizing cloud storage that use a recursive look ahead adaptive MSB prediction approach. The paper also proposes a three-level image encryption approach where on the first level, the image is subdivided into 4 × 4 blocks and the blocks are permuted. In the second level, two different neighbourhoods namely the middle neighbourhood and peripheral neighbourhood are estimated, from which the elements of the middle neighbourhood are permuted within the respective neighbourhood. In the third level, the elements of the peripheral neighbourhood without including the elements of the middle neighbourhood are permuted within the respective neighbourhood. The image that was encrypted by the image owner was uploaded to the cloud. Out of five different neighbourhoods estimated on the 4 × 4 blocks, the best neighbourhood is then estimated from the encrypted image which provides a maximum embedding capacity. The data is then embedded in the best neighbourhood using the adaptive MSB prediction algorithm. Once the embedding iteration is completed, the marked encrypted image obtained on the previous iteration is again evaluated for the best neighbourhood. This recursive process is repeated till the embedding capacity of the best neighbourhood is less than the threshold. The standard test images from the datasets BOSS base, UCID and BOWS-2 were used to evaluate the proposed approach using measures like embedding rate, SSIM and PSNR. The suggested method offers an average embedding rate that is greater than previous recent RDH-EI approaches, at 3.714 bpp, 3.4826 bpp and 2.9412 bpp for the datasets BOSS base, BOWS-2 and UCID, respectively.

Published: October 2023

El propósito de este trabajo es presentar un caso de uso de las tecnologías para apoyar a estudiantes con discapacidad auditiva en un centro de educación superior de Ecuador. En concreto, se analiza la percepción estudiantil respecto a la utilización del video con subtítulos para la formación, la comprensión de contenidos y el aprendizaje. Para la investigación se construyó un diseño metodológico mixto, de corte descriptivo. Para ello, se confeccionó un cuestionario de 22 ítems que combina la escala de Likert con preguntas cerradas y abiertas, y se lo aplicó a una muestra de 40 estudiantes de la Tecnología Superior en Administración de un instituto de Guayaquil. Los resultados revelan la percepción positiva del alumnado con discapacidad auditiva ante el uso del video con subtítulos, e informan sobre la mejor comprensión de contenidos teóricos a partir de la utilización de esta herramienta tecnológica en estudiantes con y sin discapacidad auditiva. También se constata una mayor motivación en el proceso de enseñanza-aprendizaje con el uso de este recurso entre el alumnado con discapacidad auditiva. Estos resultados permiten confirmar las bondades del video subtitulado, lo que debería animar a su implementación en entornos de aprendizaje por parte del profesorado de educación superior.

Published: October 2023

The paper employs genre analysis to investigate the pragmatic functions of complaint responses of five-star hotels in China. The study first summarizes the move structures of complaint responses at the macro level and then explores the realization process of the main moves on the communicative purpose. Based on previous studies and data analysis, there are four moves and fourteen sub-moves in complaint responses. Grounding the theoretical framework of rapport management, the study identifies the relation-oriented, task-oriented, and promotion-oriented functions of moves in Chinese hotel complaint responses. Besides, this paper compares the differences between various functions to summarize the response strategies suitable for Chinese hotels. Overall, the present study sets up a more comprehensive move framework of online business complaint responses, which can help to strengthen the interpretation of consumer complaints and provide references for enhancing customer satisfaction and maintaining a harmonious relationship with customers.
