Retos y desafíos de la implementación de la educación a distancia en el sistema educativo
Authors: Rodríguez Zavala Luisa
Published: October 2022

El presente artículo tiene como finalidad explorar la implementación de la educación a distancia en el Perú. Para lo cual, nos proponemos hacer una aproximación teórica al concepto de educación a distancia. Es en esta, donde emergen dos conceptos que serán clave para la implementación de la educación a distancia: virtualidad y tecnologías. Ambas resultan vitales para la educación a distancia. No obstante, considerando ciertos aspectos estructurales, sociales y económicos se apreciará que, si bien, la educación a distancia exige ciertas condiciones socioeconómicas mínimas para que pueda ser viable, su implementación en el Perú ha omitido ello, implementando una educación a distancia sin considerarlos; ello ha ocasionado que muchos estudiantes tanto de nivel primaria, secundaria como universitarios se vieran en la obligación de dejar sus estudios por falta de recursos económicos. Ante ello, emerge la necesidad de una educación a distancia inclusiva; por lo cual metodológicamente haremos una revisión teórica y epistemológica de los principales paradigmas existentes dentro de la educación a distancia y la virtualidad. Metodológicamente es un estudio longitudinal que abarca los años 2000 – 2020. Por lo cual, el trabajo se sostendrá en una metodología exploratoria.

El presente trabajo tiene como objetivo evaluar las diversas dimensiones asumidas por miembros de la élite incaica en la explicación y justificación de los procesos políticos, económicos y culturales que surgieron como consecuencia de la invasión española en los pueblos del Tawantinsuyo.  Se ha empleado el método hermenéutico con el propósito de interpretar el contexto histórico social andino desde las obras de sus autores más representativos. En este sentido, destacan la denuncia de la opresión política y de la enajenación cultural de los pueblos indígenas, sistematizada por Guamán Poma de Ayala, y la propuesta de integración andina-española a través del mestizaje cultural, desarrollada por Inca Garcilaso de la Vega.
Don Dimas de la Tijereta y el oficio de escribano en Lima Precisiones históricas en base a una tradición limeña
Authors: Chuhue Huamán Richard
Published: October 2022

Dimas de la Tijereta es una de las más conocidas y difundidas tradiciones que nos legó Ricardo Palma Soriano (1833 – 1919). En dicho relato se alude al personaje principal configurándolo como el presidente del gremio de escribanos limeños, entidad que existió en la vida real y sobre la que en las siguientes líneas detallaremos aspectos, a la par de también expondremos características y singularidades sobre el oficio de escribano en el Perú colonial. Con este artículo también queremos poner en precisión algunos de los datos históricos de la tradición mencionada, puesto que si bien es cierto Palma es un literato que recrea situaciones del pasado peruano a través de su prosa, estás merecen ser entendidas en su real contexto y detalle.

Authors: Saleem Asma , Saleem Asma , Amir Maqbool Syed , Huzaifa Shah Syed Muhammad , Waqar Muhammad Atif
Published: October 2022

Synovial sarcoma is a rare malignant neoplasm of young adults with poor survival. These usually arise from large joints and articular tendons. We describe an unusual case of synovial sarcoma arising from the left retromolar trigone upon initial presentation. To the best of our knowledge, this case is the only patient with left retromolar trigone involvement recorded in the literature. A 33-year-old female presented to us with complaints of a lesion in the left retromolar trigone. An ulcerated lesion with irregular margins and a smooth base was noted at the left retromolar trigone. CT scan demonstrated a soft tissue mass predominantly involving the left buccal space measuring 5.0 × 4.2 × 2.8 cm superiorly extending into the left infratemporal region, closely abutting posterior lateral of the left maxillary sinus with gross bone thinning. Biopsy was taken from the temporal and infratemporal region, which was positive for synovial Sarcoma. She received 2 cycles of neoadjuvant chemotherapy AIM protocol followed by wide local excision, however, the margin status could not be ascertained. Subsequently, treatment with a total of 60 Gy adjuvant radiotherapy was given. Patient tolerated the treatment well and remained disease-free for 4.5 years. She then developed biopsy-proven recurrence at the primary site; her metastatic workup was negative. Unfortunately, the patient was lost to follow-up for 2 years and then presented with a very large lobulated mass in the left infratemporal fossa, now measuring 6.2 × 7.6 × 6.3 cm, encasing ramus of mandible, temporomandibular joint and muscle of mastication with intra-orbital extension. She received 2 cycles of chemotherapy with gemcitabine and docetaxel. However, she did not tolerate the chemotherapy well. Subsequently, she developed tumor bleeding and received palliative radiation for bleeding and pain control. Patient is now on the best supportive care, her general condition deteriorating rapidly with the passage of time. Synovial sarcoma of the retromolar trigone is a rare malignant tumor with a poor prognosis. As there is no standard treatment protocol for synovial sarcomas of the head and neck, optimal antineoplastic treatment remains unclear. Mainstay of treatment is surgical resection with high relapse rates. Radiation therapy, with or without chemotherapy, appears to improve survival.
Regenerative and Endoscopic Treatment of Complex Recurrent Fistula in Ano: When Technology Supports Clinical Treatment
Authors: De Monti Marco , De Monti Marco , Cestaro Giovanni , Regusci Luca , Fasolini Fabrizio , Galetti Ken
Published: October 2022

Background: Recurrent anal fistulas present a challenge to surgeons due to the high risk of post-operative incontinence caused by repeated surgery. The correct identification of the anatomy of the main and secondary fistula tracts and the individuation of abscess cavities are fundamental for correct treatment. Intraoperative endoscopic evaluation and the complete destruction of the fistula pathway can be achieved through video-assisted anal fistula treatment (VAAFT). Furthermore, the injection of human autologous Microfractured Adipose Tissue (MFAT) processed by a Lipogems® device can be used as both a bulking agent and a regenerative technique.
Methods: A combined approach of VAAFT plus Microfractured Adipose Tissue Graft (MFAT) is proposed in order to treat recurrent and complex fistula in ano.
Results: Three cases treated with a combination of VAAFT and MFAT grafts are described. All cases had undergone multiple interventions at the perianal level over a period ranging from 1 to 15 years. One case certainly failed due to poor patient compliance, but in the remaining two cases, the patients made a complete recovery with the disappearance of symptoms over a follow-up period of one to two years.
Conclusion: The combination of video-assisted anal fistula treatment and injection of human autologous microfractured adipose tissue may be a valid, safe and feasible therapeutic option. MFAT injections are more effective in promoting tissue regeneration than simply “filling” the fistula tract and are common practice also in the treatment of Crohn’s Disease due to the immunomodulatory power of mesenchymal cells.

Published: October 2022

The goal of the present study is to investigate, delineate, and evaluate the shallow Miocene groundwater aquifer with vertical and lateral facies variations in the Gara oasis, western desert of Egypt. This oasis represents a typical arid region in North Africa. Through grid texture analysis, lineament detection, edge detection, thresholding, and identifying areas of structural complexity from the filtered residual reduced-to-pole magnetic anomaly map, it is possible to outline the fracture zones that principally control the groundwater aquifers and water flow in the area. The groundwater quality and quantity are examined hydro-geochemically through nine groundwater samples that were gathered from wells and springs distributed throughout the area around Gara Lake. Measurements of physio-chemical parameters (TDS, pH, and EC) are carried out and its spatial distribution is critically studied. The results reveal that the ion-exchange process caused by water-rock interaction is the dominant process. Furthermore, the main ions in the groundwater in the study areas were Na and Cl. This might be due to evaporation or halite dissolution with the upward flow of waters through the fractures from the deep aquifer of the Nubian sandstone to the shallow aquifer of the fractured Miocene limestone.

Published: October 2022

This study aims to explain the strategy of the Yogyakarta Tourism Office in the economic recovery of the tourism sector during the Covid-19 period. So far, tourism has become the fourth largest sector that contributes to the country's foreign exchange after palm oil (CPO), oil and gas and mining (coal). The world of tourism has been hit by the Covid-19 pandemic. Since the Covid-19 outbreak, all sectors have experienced a drastic decline, including the tourism sector, which has been in the second position as Indonesia's second largest foreign exchange contributor. This pandemic condition is forcing tourists to cancel their travel plans to Indonesia, one of which is the city of Yogyakarta. Based on statistics, Yogyakarta has the title of the tourism city most affected by the Covid-19 pandemic. In just over a year, the tourism industry in the city of Yogyakarta suffered losses of up to Rp. 10 trillion. This is because Yogyakarta is the second most popular tourist destination in Indonesia after Bali. It is undeniable that Yogyakarta tourism has a great influence on the community's economy. The method used in this study is a qualitative method with a descriptive type of research. The findings of this study are the Yogyakarta’s Government Tourism Office (Dinpar) in its efforts to restore the tourism sector economy through the implementation of the Covid-19 protocol; new normal policy; implementation of CHSE (Cleanliness, Health, Safety, and Environment Sustainability); restoration of MICE (meetings, incentives, conventions, exhibitions); domestic tourism; and events gradually; revitalization of the agrarian sector through the development of agribusiness.
Aspects of design management in the context of technological innovation centers
Authors: Da Silva Cássia Regina D’Antonio Rocha , De Souza Abud Ana Karla , Da Cruz Cleide Mara Barbosa
Published: October 2022

The organizational structure of the Technological Innovation Centers (NITs) integrates diverse and complex management routines that, in general, impact on the capacity of Scientific and Technological Institutions (ICTs) to effect the transfer of technology. In this sense, the NITs seek means and tools capable of assisting in the operationalization of these administrative processes. Among the various possibilities, this article brings, in particular, the conceptual approach to design management. Design management establishes recommendations for the use of design resources according to institutional goals. Based on this approach, the article aims to identify management activities within the NITs and their relationship with design management. To this end, a literature review was carried out to build the theoretical framework, a documentary research to survey the innovation policy indicators (Ministério da Ciência, Tecnologia, Inovação e Comunicação [MCTI], 2019) and application of a likert-type questionnaire in consultation with five technological innovation environments in the region Northeast of Brazil. The study is classified as applied research with a qualitative approach with an exploratory and descriptive objective. The research showed that despite the understanding of the potential of design to promote technological innovation, design management is not a practice systematically integrated into the management processes of the NIT. Subsequently, it was possible to present a set of propositions for the application of design management that support the combination of the essential and complementary activities of the NIT for the transfer of technology.

The use of virtual and digital technological resources is a phenomenon that crosses humanity in such an intense way that it often interferes with the existential naturalness of individuals and allows to launch to the world, even if in a subtle and gradual way, a relationship of mastery of the machine with the mankind. The work aims to make the reader aware of the problem of the human-machine relationship and bring paths and reflections based on a perspective of studies and debates in the field of Philosophy, about this functioning in which it can generate a subservient behavior of the human as the creator of digital functions. but that loses this domain due to the self-development of the machine. The study's methodology is bibliographic research, as well as references to films and series such as Akira (1988); Neon Genenis Evangelion (1995) and Ghost In The Shell (1995) that address this issue and serve as a basis for analyzing the facts raised as problematic. The main result of the research was the discussions based on the term Cyber-pedagogy, which is replaced and empowered from a neologistic perspective that attributes this term to a pedagogical operation in which the autopoietic machine educates the individual and can subject him/her to a process of human instrumentalization, of which the human would be an instrument for the use of the machine and digital resources by losing its essence as the creator of the virtual digital resource.

Is There “a Chinese Effect” On EU-15 Foreign Direct Investment in Central and Eastern Europe?
Authors: Štiblárová Ľubica , Junáková Anna , Gregová Jana
Published: October 2022

This paper aims to empirically verify the possible existence of “a Chinese effect ”, that is, a substitution effect between the Chinese and the EU-15 investment in the Central and Eastern European (CEE) region, which has been recently involved in the Belt and Road and 17+1 Initiatives. Such an effect can result from the strengthened political orientation of several CEEauthoritarian populist and illiberal elites towards China, which can, in turn, discourage the EU-15 from investing in the CEE region. Despite intensified Sino-CEE political relations, the results of the analysis conducted on 15 CEE countries during 2010–2018 suggest that the Chinese FDI does not substitute for investment from the EU-15 market since the expectations regarding the FDI cooperation between China and the CEE region have not been met. Moreover, most of the Chinese investment has been made via mergers and acquisitions, and not via greenfield FDI, which may lead to exaggerations of the relatively weak Chinese influence in the CEE region.

Estimating Disturbance Torque Effects on the Stability and Control Performance of Two-Axis Gimbal Systems
Authors: Nguyen Ngoc Hung , Do Van Phan , Vu Hoa Tien
Published: October 2022

Introduction. Two-axis gimbal systems are applied for stabilizing and controlling the line of sight (LOS) of an optical or imaging system mounted on a moving vehicle. Gimbal systems are intended to isolate various disturbance torques and control the LOS toward the direction of a target. Two-axis gimbals can be of two main types, namely Yaw-Pitch and Swing-Roll type. In this article, we focus on investigating mathematical models of two-axis gimbals, which describe the impact of cross-disturbance torques on their stability and control performance. Simulations were conducted to compare advantages and disadvantages of the two types of two-axis gimbals.

Aim. To study mathematical models describing the impact of cross-disturbance torques on the stability and control performance of two-axis gimbals.

Materials and methods. Mathematical models of two-axis gimbal systems were synthesized by the Lagrange method. The operation of two-axis gimbal systems was simulated in the Matlab-Simulink environment. Results. Mathematical models and structural diagrams of the synthesized Yaw-Pitch and Swing-Roll gimbals were obtained. The conducted simulations of typical cases revealed different cross-disturbance effects.

Conclusion. Motion equations for Swing-Roll and Yaw-Pitch gimbals were derived using similar methodology. The impact of cross-disturbance torques on gimbal systems was evaluated. The obtained results form a basis for selecting an optimal structure of tracking systems meeting the desired characteristics.
Neural network based image classifier resilient to destructive perturbation influences – architecture and training method
Authors: Moskalenko Viacheslav , Moskalenko Alona
Published: October 2022

Modern methods of image recognition are sensitive to various types of disturbances, which actualize the development of resilient intelligent algorithms for safety-critical applications. The current article develops a model and method of training a classifier that exhibits characteristics of resilience to adversarial attacks, fault injection, and concept drift. The proposed model has a hierarchical structure of prototypes and hyperspherical boundaries of classes formed in the space of high-level features. Class boundaries are optimized during training and provide perturbation absorption and graceful degradation. The proposed learning method involves the use of a combined loss function, which allows the use of both labeled and unlabeled data, implements the compression of the feature representation to a discrete form and ensures the compactness of the distribution of classes and the maximization of the buffer zone between classes. The main component of the loss function is the value of the normalized modification of Shannon's information measure, averaged over the alphabet of the classes, expressed as a function of accuracy characteristics. Simultaneously, accuracy characteristics are calculated on the basis of smoothed versions of the distribution of statistical hypothesis testing results. It is experimentally confirmed that the proposed approach provides a certain level of disturbance absorption, graceful degradation and recovery. During testing of the proposed algorithm on the Cifar10 data set, it was established that the integral metric of resilience to tensor damage by inversion of one randomly selected bit is about 0.95 if the share of damaged tensors does not exceed 30%. Also, during testing of the proposed algorithm, it was established that an adversarial attack with a disturbance that does not exceed the L∞-norm threshold equal to 3 provides resilience that exceeds the value of 0.95 according to the integral metric. Additionally, the integral metric of resilience during adaptation to the appearance of two new classes is 0.959. The integral metric of resilience to the real drift of concepts between the two classes is 0.973. The ability to adapt to the appearance of new classes or the concept drift has been confirmed 8 times faster than learning from scratch.

Published: October 2022

This article describes a solution for learning how to build the method of frequency characteristics of the control object. Nowadays, the level of competencies required in the work of a modern engineer is becoming higher and higher, and the more difficult it is to provide the necessary level of knowledge and skills using only the traditional approach. This problem can be solved by implementing automated learning systems that will relieve teachers, reach more students, and unify the quality of work. The subject of the research is the possibility of building a certain abstract system that will be able to provide complex skills for students in an automatic mode. The basis for this research is a complex task that requires various skills from the learner.  As a system that requires well-developed skills, we can cite the system of construction of the frequency characteristics of the control object. This work studied the methods for building such systems, as well as to study the learning ability of students and for extracting the most frequent and possible errors of students. The goal is to design and run a system that allows the student to acquire skills in constructing the frequency characteristics of an object. This work allows use of one of the possible methods for implementing such a task, as well as identifying the most common problems at the stage of learning this technique and the most successful method to prepare the system for use. In the process of the task, the following results were obtained: student errors were identified and classified. Based on the signal-parametric approach to the diagnosis of faults in dynamic systems, mathematical diagnostic models were created, that allow the system to identify classes of errors by comparing the calculation results of the student and the calculation results of the system. The peculiarities of the application of the proposed diagnostic models are presented. The intelligent tutor system is developed and used in practical classes on "Theory of automatic control" by third-year students of the National Aerospace University “Kharkiv Aviation Institute”.
Efeito de promotores tumorais em pele de gerbil, Meriones unguiculatus
Authors: Guzmán-Silva Maria Angélica
Published: October 2022

Supondo que a resistência relativa da pele de gerbil adulto à carcinogênese química estaria relacionada a um fenômeno de adaptação ao processo de promoção tumoral, foi caracterizado o efeito de óleo de cróton (OC) e peróxido de benzoíla (PB) sobre a pele de gerbil, através do estudo das alterações morfológicas, correlatas à atividade promotora e induzidas em função da dose administrada, da freqüência do tratamento e da associação ao iniciador metilcolantreno (MC) em modelos bifásicos e trifásicos de carcinogênese. Verificou-se que uma única aplicação tópica de 00 (0,94 mg e 1,88 mg) ou PB (20 mg e 40 mg) induz, na epiderme interfolicular, grau similar de hiperceratose e hiperplasia dose-dependente; outros efeitos, como espessamento da epiderme, hipertrofia celular e inflamação, eram mais acentuados pelo tratamento com OC. O efeito hiperplásico, também mais acentuado com OC, decorreria do estímulo proliferativo e do desequilíbrio entre proliferação e diferenciação epidérmica. O tratamento tópico repetido, com OC (1,41 mg) ou PB (30 mg), independente da freqüência semanal, bi-semanal ou tri-semanal, determinou diminuição do estímulo proliferativo inicial, além de intensa hiperceratose e regressão da hiperplasia, no caso do OC conseqüente ao desequilíbrio entre proliferação e diferenciação, favorecendo a perda celular. Entretanto, o PB, quando aplicado 2 ou 3 vezes/semana, determinou discreta progressão da hiperplasia inicial, decorrente de ligeiro desequilíbrio entre proliferação e diferenciação, prevalecendo discreto ganho celular. Ambas substâncias diferiram também no efeito inflamatório, ocorrendo regressão com OC e progressão com PB. A divergência nos efeitos hiperplásico e inflamatório estaria refletindo mecanismos de ação distintos destas duas substâncias. Ao ser aplicado OC ou PB após MC (0,2 mg), segundo protocolos de carcinogênese bifásica ou trifásica, comprovou-se que apenas o PB tem discreto efeito promotor - propagador – de papilomas na pele de gerbil adulto. Considerando a diminuição do estímulo proliferativo, que ocorre durante o tratamento repetido com OC e PB, associada ao efeito destas substâncias sobre a diferenciação celular - hiperceratose - entende-se que a expansão clonal seletiva de células epidérmicas estaria prejudicada, principalmente com OC, sendo talvez esta a base biológica da resistência relativa da pele de gerbil adulto à indução química de tumores de linhagem epidérmica.

Published: October 2022

The aging process can be slowed by reducing the calorie intake consumed by the body by calorie restriction or fasting. This study aimed to analyze the effect of calorie restriction on adipose tissue in mice. The experimental research design uses 12 months old Rattus Novergicus Strain Wistar, weighing 250–300 grams. The intervention was carried out for 14 days, then the average weight of subcutaneous and visceral fat was measured using Kruskal Wallis analysis and ANOVA. Based on the four treatment groups, the mice fasting and given a high-calorie diet (group 4) had the highest average fat weight value of 4.02 grams in the subcutaneous and 3.55 grams in the visceral area. Meanwhile, in group 1, mice that were not fasting and did not get a high-calorie diet had the lowest average fat weight values, namely 2.14 grams in the subcutaneous area and 2.72 grams in the visceral area. Based on the test results, it was found that there was no difference between subcutaneous (p=0.121) and visceral (p=0.443) fat tissue in all groups. Calorie restriction is beneficial for delaying aging and increasing mammal life span, but intermittent calorie restriction does not affect adipose tissue.
Representación del colectivo LGBT+ en la ficción televisiva española contemporánea (2015-2020)
Authors: Sánchez Soriano Juan José
Published: October 2022

La investigación examina la construcción de personajes LGBT+ en la ficción seriada española incluida en plataformas de distribución en la última década. Se utiliza un análisis crítico del discurso articulado en un nivel macro, donde se estudian los grandes discursos, y en un nivel micro, donde se presta atención a las temáticas, la lexicalización y las estructuras proposicionales. Los resultados muestran, entre otros, la perpetuación de estereotipos recurrentes, la ubicación marginal de estos personajes y que la construcción de la realidad LGBT+ se presenta de manera negativa o ambigua.
Centralized and Decentralized Approaches to Water Demand Management
Authors: Xiao Yi , Fang Liping , Hipel Keith W.
Published: October 2022

Centralized and decentralized procedures to assess the impacts of water demand management on a water system and its users are investigated and compared. Within the centralized approach, a system-wide optimization technique is firstly utilized to estimate the overall optimal net benefits when the water demand management initiatives are implemented. Cooperative game-theoretic methods are used to fairly redistribute the additional net benefits. In terms of the decentralized perspective, an agent-based modelling framework is adopted to permit each user to make independent decisions on whether to conserve water or consume extra water and how much to conserve or consume by solving individual optimization problems. For comparison purposes, both the centralized and decentralized approaches are applied to a case study reflecting an actual situation in the South Saskatchewan River basin in Alberta, Canada. Both methods provide positive incentives to encourage users to conserve water while maintaining at least the same level of economic benefits such that system-wide productivity is improved. Moreover, the study demonstrates that the centralized method produces greater overall net benefits, but the users may be less motivated to participate.
Mindfulness for children and adolescents with health-related challenges: a systematic literature review
Authors: Le Pouesard Morgane
Published: October 2022

This systematic literature review examined the current research on mindfulness for the well being of children and adolescents with health-related challenges, for the purpose of identifying best practices. Rigorous methods were applied to select evidence published in the past 10 years, resulting in 19 studies eligible for inclusion in the review. These studies were then presented, organized by the children’s different diagnoses, in order to provide a critical overview of the current evidence. Prominent themes in the literature were reviewed, including adaptations to
mindfulness programs for use with children, scales employed to measure mindfulness, and gaps in research. Implications for practice were presented, such as the importance of including caregivers in children’s interventions, the need to incorporate play and games, and the necessity that interventions be delivered by individuals experienced in mindfulness meditation.
Seeking equity for mental health in public education in Ontario: a critical discourse analysis of four policy documents
Authors: Lee Shawna
Published: October 2022

Through the use of critical discourse analysis (CDA), this research study conducts a comparative policy analysis which deconstructs the implicit and explicit policy components representing children‘s mental health in the revised Health and Physical Education Curriculum (2010), Realizing the Promise of Diversity: Ontario’s Equity and Inclusive Education Strategy (2009), Ideas and Shared Practices: Foundations for a Healthy School (2006), and Caring and Safe Schools in Ontario: Supporting students with special education needs through progressive discipline, kindergarten to grade 12 (2010). Underlying assumptions and contradictions regarding children‘s mental health in these policy documents are identified. Findings indicate that mental health remains misunderstood, poorly represented, and highly stigmatized in Ministry of Education policy documents, and that neither separately, nor together, are these policies sufficiently able to educate and address the reality of mental health challenges and mental illness among children.
Adaptive communication for development matrix: enhancing tangible development efforts through communication approaches and technologies
Authors: Munier Nayeem Sebastian
Published: October 2022

This paper proposes to research and establish a framework that enables individuals and organizations to maximize the impacts tangible interventions and assistance can have within marginalized/at risk communities, through communication for development approaches and technologies. By adding this extra layer to the framework of
development efforts, we can look to better Improve and Assist the growth of a marginalized community, adding an ideological layer, worthy of a communication system, that enables a sense of community and empowerment, initiates upward mobility for future generations in addition to improving quality of life. The matrix would be adaptive to any circumstance or region, as it will act as a matrix in which the communication approaches and interventions are determined based on specific indicators. The goal is to be adapted into various development efforts and produce
information and data in relation to the power communication can have within developing communities.
Are some feelings just too big for child care?: An exploratory study of Early Childhood Educator’s interpretations of internalizing and externalizing behaviours
Authors: Apostolopoulos Marina
Published: October 2022

Young children are at high risk for exposure to trauma and adverse childhood experiences, yet mental health services are limited for this age group. Children’s emotional pain is manifested in their behaviours, which are referred to as externalizing (e.g., aggression) and internalizing (e.g., anxiety) behaviours. Early Childhood Educators (ECEs) are bound to encounter children who exhibit this type of behaviour without knowing what it could mean. Therefore, this online mixed method pilot study examined the interpretations that ECEs used to determine the causes of behaviour, and their awareness of emotional distress in very young children in three written case vignettes. It also explored the strategies that ECEs engage in when responding to a child in distress. The findings provide insight to the gaps in pre-service education on children’s emotional health, and communicates the need for a trauma-informed approach to childcare.

Aluminum Based Nanosensors for Ultrasensitive Bio-Detection
Authors: Ganesan Sri Sankari
Published: October 2022

A 3-dimensional, biocompatible Aluminum based nanomaterial with tunable morphological properties is fabricated using Femtosecond Pulsed Laser system. The novel material synthesized is characterized to define its physical and optical properties owing to its purpose in the desired field. Two unique shapes of Aluminum nanostructures, multifaceted and spherical, are defined and tested for Raman activity in SERS based applications. The nanoprobes are analysed in the field of chemical sensing using Crystal Violet and Rhodamine 6G and bio-sensing using cysteine and carcinoembryonic antigen. The nanoprobes possess the ability of SERS excitation up to single molecule sensing. The research is extended to in-vitro cancer diagnosis by its ability to sense the intracellular biomarkers produced by the cancer cells. Three cell lines are evaluated, mammalian fibroblast and pancreatic and lung cancer cells, for which further analysis is performed to prove the viability of the nanoprobes to differentiate between cancerous and non-cancerous cells by implementing ratio analysis on the obtained SERS spectrum
Air quality improvement in urban areas using traffic operation management
Authors: Schappacher Jan
Published: October 2022

Clean air is becoming a valuable good while the exhausts and physical processes from road transportation
cause more and more pollutants. Critical air pollutants like particulate matter, nitrogen oxides and volatile organic compounds have severe effects on the respiratory track for adults and children. To mitigate these adverse health effects, a strict set of regulations from the governments are in place. Especially the traffic sector provides a lot of opportunities to reduce the emissions of these pollutants.
The focus of this report is fast responding traffic operational measures. Compared to long term developments like emission standards for new vehicles, these measures are able to reduce emission significantly within a few years or shorter periods of time. A research on applied measures in Toronto, Canada and Karlsruhe, Germany, has shown, that alternative modes of transportation like cycling and public transit have the highest efficiency to reduce the burden of air pollution.
Versatile medium access control (VMAC) protocol for mobile sensor networks
Authors: Ngo Vincent
Published: October 2022

In this thesis, the problem of mobility handling in wireless sensor network is introduced with an appreciation for the applications that may be possible once the problem is resolved. Mobility handling is solved with a simple priority backoff technique inspired by novel MAC protocols. To incorporate this technique for stationary and mobile sensor nodes, a hybrid MAC protocol called VMAC is designed with a fixed frame length.
VMAC combines the advantages of scheduled-based MAC for energy savings and contention-based MAC for short transmission delays. To exploit network bandwidth, channel reuse is encouraged and is readily integrated into the protoco\. To evaluate VMAC and its performance when compared to other MAC protocols, an implementation inside NS-2 is conducted with simulations of various topologies. These topologies vary in hop-count from source to destination and also contention levels. Simulation results show that VMAC with certain frame lengths are suited for selected topologies, but the frame length of one can always provide sufficient performance. The backoff technique is shown to be fair when nodes contend for medium access and it is even resourceful in speeding up hardware address resolution and routing.
