Published: April 2023

Le llamamos envejecimiento humano a un proceso gradual y adaptativo de tipo biológico, psicológico y social, producido como consecuencia de cambios genéticamente programados, historia, estilos de vida, ambiente y condiciones sociales a las que estuvo expuesta la persona.  En cambio, la vejez es una etapa de la vida cuyo inicio lo establece la sociedad, de ahí que la Organización de las Naciones Unidas acordó que, en los países en desarrollo, se catalogue como adultos mayores a las personas de 60 y más años.

En los adultos mayores institucionalizados la prevalencia de las úlceras por presión es un tema preocupante en la elaboración de los planes de cuidados de enfermería. El encamamiento prolongado, movilidad reducida, malnutrición, alteraciones fisiológicas, la incontinencia entre otros son causas que pueden provocar las ulceras por presión, así como los aspectos relacionados con las estrategias y prácticas actuales de prevención de las mismas en los pacientes de un centro sociosanitario. Lo anterior se considera importante porque durante el envejecimiento se producen cambios estructurales y funcionales en diferentes órganos y sistemas. Por tal motivo, como profesionales de la salud, debemos de conocer los cambios morfológicos y funcionales normales del envejecimiento fisiológico, y así orientar al adulto mayor para que adecue y mejore su estilo de vida.

THE “HOMECOMING” OF NANDANA IN THE HERO’S WALK: THE QUEST FOR IDENTITY
Authors: . Dr. Kalplata
Published: April 2023

In 2001 Anita Rau Badami, a writer of Indian descent living in Canada, wrote her second novel, The Hero’s Walk, where she portrays the life of Sripathi Rao, a middle-aged family man working as an advertising copywriter in a small city on the Bay of Bengal. Female characters surround Sripathi; on the one hand are her domineering octogenarian mother, his 44-year-old unmarried sister and a subservient wife; on the other hand, his daughter Maya is living with her husband in Vancouver. As fate unfolds, his daughter and her husband are killed in an accident, and Sripathi decides to bring back his seven-year-old granddaughter, Nandana, to India. Shocked by the death of her parents, Nandana remains, in the novel, a mute spectator of the contradictions and woes of Indian society, such as the “stench of fish, human beings, diesel oil, food frying, poor drains, chaotic traffic and pervasive corruption”. In this paper, we are interested in studying the youngest of the female characters, Nandana, a girl carrying two cultures, Indian and Canadian and according to Nirmala, the wife of Sripathi, is “HALF-FOREIGN”. She is aware of Hindu Gods through the stories narrated by her mother, Maya. She also leant a little Kannada from her. However, in India, the Hindu culture and Indianness confuse her. Confused in her “new” family, Nandana prefers to call herself a “Canadian”. In the end, these questions need to be answered, where does Nandana “belong”? This paper attempts to delve into this question through Badami’s Nandana.

THE SPIRIT OF VATICAN II: THE IDEALIST ASPECTS OF LITURGICAL ARCHITECTURE IN EUROPE
Authors: Katona Vilmos
Published: April 2023

The purpose of this study is to provide a comprehensive overview of the “idealist” intellectual workshops behind the 20th-century liturgical architecture before and after the Second Vatican Council. These workshops established their concepts on the intriguingly historic presumption that, in order to refresh the Catholic liturgy, one must seek and return to the origins of Christianity. In other words, their worldview was characterized by the spirit of ressourcement, which was one of the great motivators of the new liturgical paradigm brought about by 1962. Ressourcement had both monastic and secular aspects to the invocation – or recreation – of the early apostolic communities by means of new spatial and contextual programs in contemporary church architecture. These programs were conceptually compound, and were often guided or implemented by the clergy itself. The study also sheds light on some of the 21th-century interpretations and the survival of the same ideas in today’s architectural culture.

Authors: Wakabayashi Taku , Torjani Ava , Mahmoudzadeh Raziyeh , Swaminathan Shreya , Mansour Hana A. , Salabati Mirataollah , Yonekawa Yoshihiro , Regillo Carl D.
Published: April 2023

Background and Objective:

To utilize quantitative ultra widefield retinal imaging to investigate the risk factors associated with the incidence and severity of postoperative epiretinal membrane (ERM) in patients who underwent primary rhegmatogenous retinal detachment (RRD) repair.

Patients and Methods:

This retrospective study included patients who underwent pars plana vitrectomy (PPV) with scleral buckle (SB) for RRD, without a prior history of ERM, and who underwent ultra widefield imaging postoperatively between June 2020 and February 2022. The size and location (distance from the macula) of the drainage retinotomy and the area of peripheral pathology, including retinal breaks and laser scars, were quantitatively measured with cloud-based software. The severity of postoperative ERM formation at 6 months was graded from grade 1 to 4. We investigated the risk factors that were significantly associated with the incidence and severity of postoperative ERM at 6 months.

Results:

We included 80 eyes (80 patients) in this study. Postoperative ERM developed in 37 eyes (46%) at 6 months. The severity of ERM was grade 1 in 24 eyes (65%), grade 2 in 6 eyes (16%), grade 3 in 4 eyes (11%), and grade 4 in 3 eyes (8%). Postoperative ERM was not associated with the presence or the location of drainage retinotomy (P= 0.836 and 0.820, respectively). However, it was significantly associated with larger surface area of drainage retinotomy (P= 0.039). In addition, postoperative ERM was significantly associated with a larger area of peripheral pathology (P= 0.012), a larger extent of RRD (P= 0.013), vitreous hemorrhage (P= 0.026), redetachment within 6 months (P= 0.022), use of silicone oil as a tamponade (P= 0.047), and number of surgeries within 6 months (P= 0.027). These factors, in addition to 360° endolaser, were also significantly associated with the severity of postoperative ERM. In multivariable linear regression analysis, the only variable that remained statistically significant was the size of the drainage retinotomy (P= 0.023).

Conclusion:

The pathogenesis of postoperative ERM is multifactorial. Large drainage retinotomies may increase the risk of ERM formation.

Characterizing and Predicting Limited Early Response in Eyes With Retinal Vein Occlusion Using Machine Learning in Routine Clinical Practice
Authors: Kailar Roshni S. , Perkins Scott W. , Kuo Blanche L. , Singh Rishi P.
Published: April 2023

Objective:

To characterize and predict limited early responders (LER) in eyes with retinal vein occlusion (RVO) treated with anti-vascular endothelial growth factor (anti-VEGF).

Patients and Methods:

This retrospective cohort study of 116 eyes with edema secondary to RVO characterized early responders (ER) and LER 3 months after initiating anti-VEGF treatment. Baseline characteristics and 12-month outcomes were compared. A machine learning (ML) algorithm was developed to predict LER.

Results:

At baseline, LER had higher best-corrected visual acuity (BCVA) than ER (
P
< 0.0001) and lower central subfield thickness (CST) than ER (
P
< 0.01). At 12 months, change in BCVA was + 0.8 and + 21.4 letters, and change in CST was −104.4 and −187.1 μm for LER and ER, respectively (
P
< 0.0001,
P
< 0.05). The ML algorithm achieved area under the receiver operating characteristic curve = 0.73.

Conclusion:

ER eyes experienced greater functional and anatomical improvements at 12 months in routine clinical practice than LER. The ML algorithm achieved moderately high performance predicting LER.

Motif adjacency matrix and spectral clustering of directed weighted networks
Authors: Wang Yike , Wang Gaoxia , Hou Ximei , Yang Fan
Published: April 2023

In the spectral clustering methods, different from the network division based on edges, some research has begun to divide the network based on network motifs; the corresponding objective function of partition also becomes related to the motif information. But, the related research on the directed weighted network needs to be further deepened. The weight of the network has a great influence on the structural attributes of the network, so it is necessary to extend the motif-based clustering to the weighted network. In this paper, a motif-based spectral clustering method for directed weighted networks is proposed. At the same time, this paper supplements the method of obtaining matrix expressions of the motif adjacency matrix in directed unweighted networks and provides a method to deal with the weight of networks, which will be helpful for the application research of motifs. This clustering method takes into account the higher-order connectivity patterns in networks and broadens the applicable range of spectral clustering to directed weighted networks. In this method, the motif-based clustering of directed weighted networks can be transformed into the clustering of the undirected weighted network corresponding to the motif-based adjacency matrix. The results show that the clustering method can correctly identify the partition structure of the benchmark network, and experiments on some real networks show that this method performs better than the method that does not consider the weight of networks.

Authors: Behera Tapan Kumar
Published: April 2023

When it comes to software or mobile application development, it is only possible to make it successful with the help of a good architecture and the principles that govern it. It has been found that applications that use the principles of architecture are good at scalability, maintainability, availability, interoperability, and so on. The development of mobile applications should be based on SOLID principles which leads to high-quality code without any additional effort on the part of the developer. The architecture process focuses on the design of both functional and non-functional requirements for a system. By designing the architecture of a system, one can gain a deeper understanding of the bigger picture of the system as a whole. Well-designed architecture and principles play a critical role in enabling developers to build scalable and high-quality applications.

Introduction: Menstruation is a natural phenomenon that occurs with sexual maturity of females. However, the topic is taboo for most female adolescents leading to improper practices on menstrual hygiene (MH) management.
Objectives: To assess the knowledge, attitudes and practices on MH and associated factors among Grade 10 adolescent girls in Kalutara District, Sri Lanka
Methods: A descriptive cross-sectional study was conducted. The final sample size computed was 720, applying a design effect of 3.8. As the cluster size decided was 15, 48 clusters/classes were selected using multi-stage stratified cluster sampling applying probability sampling techniques. A validated self-administered questionnaire was administered using Sinhala and Tamil versions. Bivariate and multivariate logistic regression was conducted to determine the associated factors.
Results: Response rate at the time of recruitment was 100%. Satisfactory level of overall knowledge was observed in 25% (95% CI: 21.9, 28.3), attitudes in 67.2% (95% CI: 64.0, 70.9) and practices in 17.3% (95% CI: 14.7, 20.3). Unsatisfactory knowledge was associated with menstrual information not provided by a science teacher (ScT) (p<0.001) school types 1C and 2 combined (p=0.002) and mothers having less than tertiary education (p=0.03). Unsatisfactory attitudes were associated with menstrual information not provided by a ScT (p<0.001) and lack of premenarcheal awareness (p=0.009).

Practical applications of recently developed sensor fusion algorithms perform poorly in the real world due to a lack of proper evaluation during development. Existing evaluation metrics do not properly address a wide variety of testing scenarios. This issue can be addressed using proactive performance measurements such as the tools of resilience engineering theory rather than reactive performance measurements such as root mean square error. Resilience engineering is an established discipline for evaluating proactive performance on complex socio-technical systems which has been underutilized for automated vehicle development and evaluation. In this study, we use resilience engineering metrics to assess the performance of a sensor fusion algorithm for vehicle localization. A Kalman Filter is used to fuse GPS, IMU and LiDAR data for vehicle localization in the CARLA simulator. This vehicle localization algorithm was then evaluated using resilience engineering metrics in the simulated multipath and overpass scenario. These scenarios were developed in the CARLA simulator by collecting real-world data in an overpass and multipath scenario using WMU’s research vehicle. The absorptive, adaptative, restorative capacities, and the overall resilience of the system was assessed by using the resilience triangle. Simulation results indicate that the vehicle localization pipeline possesses a higher quantitative resilience when encountering overpass scenarios. Nevertheless, the system obtained a higher adaptive capacity when encountering multipath scenarios. These resilience engineering metrics show that the fusion systems recover faster when encountering disturbances due to signal interference in overpasses and that the system is in a disturbed state for a shorter duration in multipath scenarios. Overall these results demonstrate that resilience engineering metrics provide valuable insights regarding complicated systems such as automated vehicle localization. In future work, the insights from resilience engineering can be used to improve the design and thus performance of future localization algorithms.

Remote Monitoring and Teleoperation (RMTO) of Autonomous Vehicles (AV) is advancing rapidly in the industry. Researchers and industrial partners explore the role RMTO plays in helping AV navigate complicated situations, among many others. At the heart of this lies the problem of potential pathways and attack vectors or threat surfaces by which a malicious attack can be carried out on an RMTO and an AV. The separation of cybersecurity considerations in RMTO is barely considered, as so far, most available research and activities are mainly focused on AV. The main focus of this paper is addressing RMTO cybersecurity utilising an adaptable security-by-design approach, although security-by-design is still in the infant state within automotive cybersecurity. An adaptable security-by-design approach for RMTO covers Security Engineering Life-cycle, Logical Security Layered Concept, and Security Architecture. Based on the international automotive cybersecurity standards - ISO/SAE 21434, a Threat Analysis and Risk Assessment (TARA) with a formalisation of the highest level of threats identified from the TARA of the RMTO system is carried out, with corresponding mitigation actions as per UNECE WP29. The adaptable security-by-design approach has been then applied to a prototype RMTO system developed by an industrial partner. Finally, penetration testing has been carried out where the results verify the capability of the adoptable security-by-design to reinforce the security of the RMTO systems against some of the identified risks and threats.
Validation of the Arnold Render for Creation of Physically Correct Lighting Models
Authors: Vega Henry V. , Suway Jeffrey
Published: April 2023

Prior research has tested the validity of Cycles Engine render in Blender for the creation of physically correct lighting models; however, a research gap still exists in examining the use of Arnold render engine in 3DS Max for accident reconstruction and other forensic settings [1]. Specifically, the process presented in this paper utilizes the Arnold render engine within 3DS-Max to analyze the lighting models. Arnold is a physically-based render (PBR) engine and can be used to recreate an accident scene geometry and lighting conditions. The goal is to create light sources within Arnold that represent the real-world light sources. The light sources in Arnold are quantified by several variables, including intensity, color, and size. The intensity and size variables determine the self-emitted radiance of the light source and require further explanation to determine the relationship between these variables in Arnold and real-world lighting quantities. In this paper, we compare and validate the relationship between intensity units in Arnold and photometric quantities and illustrate that the lighting produced is based on the physics of light and matches Cornetto and Suway’s results [1].
Snowmobile Pole Crash Tests: Additional Testing and Analysis
Authors: Griffiths Harrison , Paquette Mark
Published: April 2023

This paper presents the results of five additional instrumented snowmobile crash tests and the updated findings when combined with the dataset from our previous publication (SAE# 2021-01-0876). This additional work expands on, and aims to better the understanding of, snowmobile collision dynamics and the severity of real-world collisions, given that minimal crash test data exists for snowmobiles compared to passenger vehicles.

In the five new tests, the test snowmobile was accelerated forward into a pole, made from a tree trunk 38 cm in diameter. The first two pole impacts were completed at low-speed (i.e., less than 15 km/h) to determine a damage threshold. The subsequent two tests targeted 40 km/h impact speeds, and the last test targeted an impact speed of 80 km/h.

From the tests, a more reliable damage threshold of 9 km/h was determined using the low-speed tests, equations were derived for the relationship between the maximum crush and the impact speed for snowmobiles sustaining frontal pole impact damage, and the data from this crash testing was combined with updated impact speed–maximum crush relationships, along with stiffness coefficients calculated in previous research.
Target Driven Bushing Design for Wheel Suspension Concept Development
Authors: Naik Akshay , Brandin Tobias , Huang Yansong , Jacobson Bengt
Published: April 2023

Bushing elasticity is one of the most important compliance factors that significantly influence driving behavior. The deformations of the bushings change the wheel orientations under external forces. Another important factor of bushing compliance is to provide a comfortable driving experience by isolating the vibrations from road irregularities. However, the driving comfort and driving dynamics are often in conflict and need to be balanced in terms of bushing compliance design. Specifically, lateral force steer and brake force steer are closely related to safety and stability and comprises must be minimized. The sensitivity analysis helps engineers to understand the critical bushing for certain compliance attributes, but optimal balancing is complicated to understand. The combination of individual bushing stiffness must be carefully set to achieve an acceptable level of all the attributes. Traditional bushing tuning method involves an optimization process in Adams Car or any other multi-body simulation software. Though they provide reliable results, it is a time-consuming process to build models for the complete Kinematic and Compliance analysis. Therefore, a method to set the bushing specifications automatically according to the compliance targets is proposed by the author. The method makes sure the instant motion of the wheel meets the targets. The bushing stiffness values are calculated according to force distribution and motion ratios between the wheel and each bushing. The method decouples the axial stiffness and radial stiffness. It provides a method to set up the radial stiffness automatically. The new method will reverse the traditional trial-and-error approach, to avoid extensive iterations and significantly reduce the development time.
Influence of Wheel Drive Unit Belt Width on the Aerodynamics of Passenger Vehicles
Authors: Josefsson Erik , Urquhart Magnus , Sebben Simone
Published: April 2023

Wind tunnels are an essential tool in vehicle development. To simulate the relative velocity between the vehicle and the ground, wind tunnels are typically equipped with moving ground and boundary layer control systems. For passenger vehicles, wind tunnels with five-belt systems are commonly used as a trade-off between accurate replication of the road conditions and uncertainty of the force measurements. To allow different tyre sizes, the wheel drive units (WDUs) can often be fitted with belts of various widths. Using wider belts, the moving ground simulation area increases at the negative cost of larger parasitic lift forces, caused by the connection between the WDUs and the balance.

In this work, a crossover SUV was tested with 280 and 360mm wide belts, capturing forces, surface pressures and flow fields. For further insights, numerical simulations were also used. It was found that the belt width can substantially alter the flow field, mainly locally around the wheels but also away from the belts. The drag coefficient increased by approximately 0.010 CD for the narrow belts, mainly due to differences in the vortex structures downstream of the front wheels, resulting in larger low-energy regions for the narrow belts. Numerical simulations showed that the change in vortex structures was caused by leakage flows from the gaps between the WDUs and the stationary floor. Comparing two rim designs, it was found that the belt width did not only affect the absolute force measurements but also the drag delta between them.

Although the parasitic lift forces increase with the wider belts, a correction is necessary regardless. Hence, given the fact that the interfering leakage flows are further away from the tyres with the wider belts, they should be the preferred choice, allowing more accurate investigations of wheel aerodynamics.
