Authors: Kong Sung Hye , Cho Wonwoo , Park Sung Bae , Choo Jaegul , Kim Jung Hee , Kim Sang Wan , Shin Chan Soo
Published: May 2023

BACKGROUND

With the progressive increase in aging populations, the use of opportunistic computed tomography (CT) scanning is increasing, which could be a valuable method for acquiring information on both muscles and bones of aging populations.

OBJECTIVE

The aim of this study was to develop and externally validate opportunistic CT-based fracture prediction models by using images of vertebral bones and paravertebral muscles.

METHODS

The models were developed based on a retrospective longitudinal cohort study of 1214 patients with abdominal CT images between 2010 and 2019. The models were externally validated in 495 patients. The primary outcome of this study was defined as the predictive accuracy for identifying vertebral fracture events within a 5-year follow-up. The image models were developed using an attention convolutional neural network–recurrent neural network model from images of the vertebral bone and paravertebral muscles.

RESULTS

The mean ages of the patients in the development and validation sets were 73 years and 68 years, and 69.1% (839/1214) and 78.8% (390/495) of them were females, respectively. The areas under the receiver operator curve (AUROCs) for predicting vertebral fractures were superior in images of the vertebral bone and paravertebral muscles than those in the bone-only images in the external validation cohort (0.827, 95% CI 0.821-0.833 vs 0.815, 95% CI 0.806-0.824, respectively; P<.001). The AUROCs of these image models were higher than those of the fracture risk assessment models (0.810 for major osteoporotic risk, 0.780 for hip fracture risk). For the clinical model using age, sex, BMI, use of steroids, smoking, possible secondary osteoporosis, type 2 diabetes mellitus, HIV, hepatitis C, and renal failure, the AUROC value in the external validation cohort was 0.749 (95% CI 0.736-0.762), which was lower than that of the image model using vertebral bones and muscles (P<.001).

CONCLUSIONS

The model using the images of the vertebral bone and paravertebral muscle showed better performance than that using the images of the bone-only or clinical variables. Opportunistic CT screening may contribute to identifying patients with a high fracture risk in the future.
Behavior Change Approaches in Digital Technology–Based Physical Rehabilitation Interventions Following Stroke: Scoping Review (Preprint)
Authors: Gooch Helen J , Jarvis Kathryn A , Stockley Rachel C
Published: May 2023

BACKGROUND

Digital health technologies (DHTs) are increasingly used in physical stroke rehabilitation to support individuals in successfully engaging with the frequent, intensive, and lengthy activities required to optimize recovery. Despite this, little is known about behavior change within these interventions.

OBJECTIVE

This scoping review aimed to identify if and how behavior change approaches (ie, theories, models, frameworks, and techniques to influence behavior) are incorporated within physical stroke rehabilitation interventions that include a DHT.

METHODS

Databases (Embase, MEDLINE, PsycINFO, CINAHL, Cochrane Library, and AMED) were searched using keywords relating to behavior change, DHT, physical rehabilitation, and stroke. The results were independently screened by 2 reviewers. Sources were included if they reported a completed primary research study in which a behavior change approach could be identified within a physical stroke rehabilitation intervention that included a DHT. Data, including the study design, DHT used, and behavior change approaches, were charted. Specific behavior change techniques were coded to the behavior change technique taxonomy version 1 (BCTTv1).

RESULTS

From a total of 1973 identified sources, 103 (5%) studies were included for data charting. The most common reason for exclusion at full-text screening was the absence of an explicit approach to behavior change (165/245, 67%). Almost half (45/103, 44%) of the included studies were described as pilot or feasibility studies. Virtual reality was the most frequently identified DHT type (58/103, 56%), and almost two-thirds (65/103, 63%) of studies focused on upper limb rehabilitation. Only a limited number of studies (18/103, 17%) included a theory, model, or framework for behavior change. The most frequently used BCTTv1 clusters were feedback and monitoring (88/103, 85%), reward and threat (56/103, 54%), goals and planning (33/103, 32%), and shaping knowledge (33/103, 32%). Relationships between feedback and monitoring and reward and threat were identified using a relationship map, with prominent use of both of these clusters in interventions that included virtual reality.

CONCLUSIONS

Despite an assumption that DHTs can promote engagement in rehabilitation, this scoping review demonstrates that very few studies of physical stroke rehabilitation that include a DHT overtly used any form of behavior change approach. From those studies that did consider behavior change, most did not report a robust underpinning theory. Future development and research need to explicitly articulate how including DHTs within an intervention may support the behavior change required for optimal engagement in physical rehabilitation following stroke, as well as establish their effectiveness. This understanding is likely to support the realization of the transformative potential of DHTs in stroke rehabilitation.

Authors: Farhany Fajrul Falah , Lutfan Lazuardi  , Dewi Ratmasari
Published: May 2023

Background: One hospital that has adapted services to the COVID-19 pandemic is the UGM Academic Hospital (RSA UGM). RSA UGM offers long-distance or telemedicine services, later named the Joempa Dokter Telemedicine RSA UGM. Joempa Dokter stands for Journey for Online Electronic Medical Professional Assistance. Telemedicine Joempa Dokter RSA UGM has been running for 1.5 years. Still, it was found that it had not been appropriately utilized by health workers who worked at the Outpatient Installation at RSA UGM. The process flow for telemedicine services was also not adequately systemized, as evidenced by using semi-conventional technology in practice.

Objective: To evaluate ‘Joempa Dokter’ telemedicine service at RSA UGM during the COVID-19 pandemic.

Methods: The type of research used in this study is a mixed method with an embedded or nested research design using a survey approach and in-depth interviews. This research was conducted in the outpatient ward of RSA UGM from July to August 2022.

Results: The flow of telemedicine services for Joempa Dokter RSA UGM starts with patient registration via the Google form, consulting with doctors via the Zoom platform, then prescribing drugs online. Telemedicine services have not been integrated with the SISTEMA RSA UGM, but this service is helpful and easy to use. There are still some deficiencies in this telemedicine service, such as unattractive features; the platform used is still different from registration to postservice; there is no Standard Operating Procedure (SOP) for Joempa Dokter Telemedicine Services; incentives are not appropriate; and telemedicine services are not a priority service at RSA UGM yet.

Conclusion: Joempa Dokter Telemedicine at RSA UGM is beneficial as an alternative solution to improve the quality of health services in hospitals during the COVID-19 pandemic. For better service continuity, UGM RSA management needs to prepare Standard Operating Procedures (SPO) and service roadmaps, adjust incentives to improve the performance and motivation of the health workers involved, and service integration with existing information systems at RSA UGM also needs to be done.

VIRTUAL REALITY AND DENTISTRY
Authors: BHATNAGAR ANAND , BHATNAGAR EVA
Published: May 2023

The field of dentistry could benefit considerably from virtual reality (VR). There will be several ways like Virtual reality can be used to teach patients about oral hygiene and dental procedures in a more dynamic and engaging way. Patients can utilize virtual reality (VR) to learn about various dental procedures, view 3D representations of their teeth and gums and comprehend how poor oral hygiene affects their general health. Many people experience fear or worry when going to the dentist, which can prevent them from getting the essential dental care. VR can reduce these anxieties by fostering a more tranquil and immersive atmosphere. For instance, patients might utilize virtual reality (VR) headsets to divert their attention during treatments or imagine serene settings to lessen anxiety. Virtual reality can also be utilized to educate and teach dental practitioners in a more effective and efficient manner. Before working on actual patients, students can perform a variety of dental operations in a virtual setting, which helps them develop their confidence and competence. VR can be used by dental practitioners to learn about new methods, instruments, and technologies. In general, the use of virtual reality in dentistry has the potential to enhance dental professional training and education, patient results, and patient involvement and satisfaction.

Authors: García Rivera Enoc Alejandro
Published: May 2023

La segunda década del siglo XXI marca el inicio del impulso estatal más importante que se le ha impuesto a la industria nacional de los hidrocarburos. Modificaciones a la Constitución, un nuevo marco regulatorio, planeaciones gubernamentales soportadas en su aprovechamiento y, sobre todo, el acrecentamiento en el número de proyectos de explotación son el mayor testimonio de ello. Este último corolario que acompaña al nuevo impulso de la industria petrolera viene acompañado de efectos que repercuten sobre bienes tutelados por los derechos humanos, como el agua, lo que genera tensiones en torno a su garantización. Por lo anterior, el presente trabajo académico tiene como finalidad examinar las implicaciones del derecho humano al agua y los efectos negativos del aprovechamiento de los hidrocarburos que atentan contra su garantización en el marco de las convenciones instauradas para este derecho.

Kinematics of Bennett Mechanism, Negative Angular Velocity
Authors: Mustafaev T.A. , Khabibullin F.F. , Faizov M.R.
Published: May 2023

This article provides reasoning and research of spatial mechanisms. The creation of the first simple Bennett mechanism obtained through the pyramid of its base and sides is described. In the pyramid, the angles of inclination and heights of the sides are determined to obtain standard equalities. Thanks to all the parameters, the theoretical link lengths that have practical values are determined. All parameters of length and angles are presented on the structural diagram for each received mechanism. On the basis of two identical, but mirrored mechanisms, a five-bar Bennett mechanism is synthesized. The five-link mechanism is obtained by mutual integration of two identical links, for which the calculation method is described. The article contains a calculation to determine the length and angle of the frame. The frame is obtained by the specified parameters of the ghost angle, the parameters of the two mirrored links derived into one expression. The specified inequality is used for a five-link mechanism in which it is obtained by a driving and a driven full-turn link. The text defines the main kinematic parameters of the links that make a complete turn around its axis without contact. All parameters of the mechanism are metered intuitively. Principle kinematic parameters of the mechanism: angular displacement, angular velocity and angular acceleration are determined. The kinematics is determined with respect to the driving and driven link, taking into account the angular displacement, speed and acceleration. For a more accurate calculation, the dependence of the additional ghost angle of the mechanism on the kinematic parameters is considered. The obtained data are visualized using diagrams of relationships of the rotation of the input link to the output using the Maple application. In trigonometric functions, there is a negative and a positive value determined by the quadrants on the sectors of the circle. Diagrams of angular displacement and angular velocity according to the calculations show negative numerical values. The angular acceleration of the driven link during the rotation of a full turn of the driving link of the mechanism changes its acceleration 4 times. The analysis of the data obtained allows us to conclude that the driven link will rotate jerkily, at these moments there is a possibility of destruction of the mechanism and an increase in the load on the driven link and imbalance of the mechanism.

Published: May 2023

The purpose of this research is to study the damage of structural metal materials by acoustic method under various external fatigue and thermal influences. A structural model describing the process of accumulation of scattered micro-damages in the material is proposed, the parameters of which can be measured by acoustic method. It is shown that irreversible processes occur in the structure of structural metal materials during cyclic loading, leading to changes in physical and mechanical characteristics. The assessment of changes in a large number of informative parameters of acoustic control in the process of damage accumulation was carried out. It is established that the parameters of elastic waves depend on the characteristics of the medium under study. It is shown that the state of the surface layer can be used in the tasks of earlier assessment of the developed resource of the structural material. A model that takes into account the influence of degradation processes of the surface layer on the parameters of surface waves is proposed. The results of experimental studies confirming the proposed model are presented. Methods for determining material mechanical characteristics are proposed: elastic modulus, yield strength, fracture toughness, internal stresses, grain size, etc. on structural elements, without violating their strength characteristics. The results of studies of medium influence on parameters of elastic waves serve as the basis for constructing a complex acoustic method for determining physical and mechanical characteristics of structural materials. Examples of practical use of the obtained results in the tasks of ensuring the safe operation of critical structural elements are considered. The data obtained during the study make it possible to assess the damaged state and properties of metal materials under cyclic loading quickly using the parameters of acoustic waves.

Published: May 2023

Abstract: An innovative system for the flexural strengthening of RC structures designated continuous reinforcement embedded at ends (CREatE) is presented in this research work. The main charateristics and procedures for the application of this new strengthening techniques were described. To evaluate the performance and efficiency of this technique, a set of RC T-beams was subjected to a four pointed bending test setup. Different application arrangements and different amount of reinforcement were considered, and the CREatE technique was tested under monotonic and cyclic loading histories. The tests were modeled using the nonlinear finite element method (FEM) to predict the performance of the RC T beam, which allowed analysing, in detail and with good agreement with the experiments, the influence of the CREatE technique on the (1) strains developed in the concrete, (2) cracking patterns, and (3) strains developed in the stirrups. Apart from the expected increases in the flexural stiffness and load bearing capacity of the T beam, the result showed that the use of the CREatE technique led to higher ductility indexes in the displacement compared with traditional techniques. Moreover, with the CREatE technique, premature debonding of the reinforcement material from the concrete tensioned surface commonly observed in externally bonded reinforcement (EBR) strengthening system was eliminate.

Published: May 2023

Abstract: Currently, inefficient soil properties are a crucial concern in engineering projects. In some cases, enhancing the characteristics of unsuitable soil is a necessary step to facilitate construction. Pavement structures built on weak soil sub grades exhibit premature distress, which leads to the early failure of the pavement. Silty soil often exhibits undesirable engineering behaviour, such as low bearing capacity, and high moisture susceptibility. Therefore, stabilizing these soils is a common practice to improve their strength.

The study has reviewed the state-of-the-art cyber-attack prediction based on Intrusion Alert, its models, and limitations. The ever-increasing frequency and intensity of intrusion attacks on computer networks worldwide intense research efforts towards the design of attack detection and prediction mechanisms. While there are a variety of intrusion detection solutions available, the prediction of network intrusion events is still under active investigation. Over the past, statistical methods have dominated the design of attack prediction methods. The analysis of dataset by supervised machine learning technique(SMLT) to capture several information’s like, variable identification, univariate analysis, bivariate and multivariate analysis, missing value treatments etc. A comparative study between machine learning algorithms had been carried out in order to determine which algorithm is the most accurate in predicting the type cyber attacks. The results show that the effectiveness of the proposed machine learning algorithm technique can be compared with best accuracy, precision, Recall, F1 Score,Sensitivity, and Specificity.
Vision AI: A Deep Learning-Based Object Recognition System for Visually Impaired People Using TensorFlow and OpenCV

Published: May 2023

Abstract: Object detection is a challenging task in computer vision that can provide valuable information for visually impaired people. In this paper, we propose a deep learning-based model that detects objects for blind people using frameworks such as TensorFlow and OpenCV. Our system uses a pre-trained model built on YOLO v7 to detect and recognize objects in real-time from images or videos captured by a camera. Other versions of YOLO have also been taken into consideration. However, based on some recent comparisons, YOLOv7 is the fastest and most accurate official YOLO version. It achieves 2% higher accuracy than Cascade-Mask R-CNN models at dramatically increased inference speed (509% faster). The results are then converted to speech using text-to-speech technology and delivered to the user through headphones or a speaker. Our system is intended to be an IoT-based project that can recognize common objects and people. We evaluated our system on several datasets such as Common Object in Context (COCO)- a large-scale labelled dataset containing 1.5 million object images, to demonstrate its accuracy and efficiency. We believe that our system can offer a practical and affordable way for visually impaired people to access visual information and enhance their quality of life.

This study aims to investigate the proficiency of prospective mathematics teacher students in mathematical representation. To achieve this goal, we used a qualitative research design with a descriptive approach. The research subjects consisted of three undergraduate students from Mathematics Education department at a private university in Yogyakarta. Data were collected using a test for mathematical representation ability and interviews. The data were analysed descriptively using techniques by Miles and Huberman. It shows that the mathematical representation ability of prospective teacher students was in low category. This can be seen from the average achievement of indicators of mathematical representation ability (34.74%). The ability to create and use representations for collecting/organizing, recording, and communicating mathematical ideas is 33.33%. The ability to select, apply and translate various forms of representation mathematics to solve problems is 29.76%. And the ability to use multiple representations is 41.11%.

The study investigated the influence of the Treffinger learning model and self-directed learning on the critical thinking skills of junior high school students. The Treffinger learning model is one of the few models addressing the problem of creativity and providing practical suggestions on how to achieve cohesion. On the other hand, self-directed learning is a mental process to increase the knowledge, skills, and self-achievement of individuals with self-planned and self-conducted activities. The research employed a post-test experiment and control group design with two groups. The study employed two groups; one group was treated using the Treffinger learning model, while the other group was treated using a conventional model. Both groups were analyzed using a self-directed learning questionnaire and a critical mathematical thinking skills test. The sample of this research comprised 88 Grade 8 students purposefully selected in relation to the research objectives. The results of the study showed that the Treffinger learning model was statistically significant in enhancing critical mathematical thinking skills compared to the conventional learning models. Additionally, the study found that students who exhibited high levels of self-directed learning were more likely to benefit from the Treffinger learning model than the conventional model, with a statistically significant mean difference of 3.05 points.

The use of social media is increasingly present in everyday life, as well as an increase in the level of anxiety. In this context, the present study aimed to analyze the relationship between the use of social media and anxiety symptoms in university students. A field survey was carried out with 148 university students of both sexes, with an average age of 25 years (SD: 9), from colleges located in the greater João Pessoa-PB. Data were collected through a sociodemographic questionnaire, the multidimensional Scale based on the Theory of Planned Behavior (TPB) and the Greenberger Anxiety Inventory, being analyzed using descriptive and inferential statistics. The results showed that most participants accessed social media daily, felt satisfied and reported having control over the frequency of use of these media, while exhibiting mild levels of anxiety. Signs and symptoms of anxiety were higher with statistical significance (p < 0.05) in participants who reported harmful effects of social media, who felt silly and needed to use them immediately. It is concluded that the use of social media can have different psychological and social impacts on the quality of life of young university students.

The high rate of deaf people in Brazil who are born in hearing families led to the questioning about how the familiar relationship is established between deaf children and hearing parents. The purpose of this project is research was to understand how the language is developed among the family members, and how their relationship is stablished according to the perspective of professional in this area. It was developed through bibliographic research in addition to semi structured interviews. The bibliographic analysis was made through fluctuating reading. The data gathered in the interviews were analyzed qualitatively, according to the referential system. The results confirmed with the bibliographical data, indicating the need to reorganize the familiar structure in both communicative and cultural aspects in case of a deafness diagnosis as well as that the lack of knowledge about such topic harms the acceptance process. The professional formations were described as insufficient while teaching about deafness. The communicative discrepancy between hearing parents and deaf children was affirmed as the motive of bigger difficulty for the development of deeper connection in their relationship. The conflict between Portuguese and Libras, the feelings generated after the diagnosis, the lack of information on the topic, the identity and the deaf cultural context are matters that interfere in the process of a deaf person as an individual and as a family member. This project completion intends to assist in the spread of information in this topic, in a way to contribute to the professional and family guidance around this topic.
