Rediseño Telemático y Mejoramiento de Enlaces de Radiocomunicación Digital para Proyectos de Conectividad Rural y Acceso a Internet en Chile

This undergraduate thesis, developed in the framework of a student exchange internship within the Universidad Tecnológica Metropolitana (UTEM), in Santiago de Chile, reports details and results of a Telecommunications Engineering project, which in its 2010 stage involves two actions which incorporate the design and implementation of low cost technical solutions for wireless connectivity and Internet access for rural schools in isolated areas of southern Chile. In order to apply the knowledge acquired during the Telecommunications Engineering curriculum and integrating it with the practical experience of applied research and interdisciplinary work, also acquired by the authors being involved in international cooperation projects for rural connectivity, this work presents two separate social-technological impact actions, namely: The complete redesign and improvement of a wide area wireless network corresponding to the infrastructure of the rural connectivity project named NET Cochamó which, since 2006 aims to provide digital connectivity and Internet access to schools in the district of Cochamó (Región de Los Lagos, Chile) through the redistribution of the available bandwidth from a local public service (Municipality). The prospective study, site visit, theoretical design and simulation of the integrated radio links system for a new network of wireless relay stations in order to replicate and scale the bandwidth and Internet access redistribution model for rural schools in another isolated Chilean place, specifically the town of Alto Bio-B́ıo in the region of the same name. Through the chapters, the contextualization of each intervention is followed by technical aspects like network topology redesign, radio links calculation and modeling, digital transmitter configurations at different levels and the implementation of physical infrastructure, as well as the measurement of radio equipment figures, antennas and wireless IP networks related parameters. Finally we provide conclusions and evaluation of results for both components of the presented work, also providing some recommendations for future design and fieldwork stages so as to guarantee the continuity and growth of the student cooperation groups for rural connectivity born in UPC and UTEM within the framework of these initiatives.
On qualitative properties of solutions to quasilinear parabolicequations admitting degenerations at infinity

We consider the Cauchy problem for a quasilinear parabolic equations 𝜌 ( 𝑥 ) 𝑢 𝑡 = Δ 𝑢 + 𝑔 ( 𝑢 ) |∇ 𝑢 | 2 , where the positive coefficient 𝜌 degenerates at infinity, while the coefficient 𝑔 either is a continuous function or have singularities of at most first power. These nonlinearities called Kardar–Parisi–Zhang nonlinearities (or KPZ-nonlinearities) arise in various applications (in particular, in modelling directed polymer and interface growth). Also, they are of an independent theoretical interest because they contain the second powers of the first derivatives: this is the greatest exponent such that Bernstein-type conditions for the corresponding elliptic problem ensure apriori 𝐿 ∞ -estimates of first order derivatives of the solution via the 𝐿 ∞ -estimate of the solution itself. Earlier, the asymptotic properties of solutions to parabolic equations with nonlinearities of the specified kind were studied only for the case of uniformly parabolic linear parts. Once the coefficient 𝜌 degenerates (at least at infinity), the nature of the problem changes qualitatively, which is confirmed by the presented study of qualitative properties of (classical) solutions to the specified Cauchy problem. We find conditions for the coefficient 𝜌 and the initial function guaranteeing the following behavior of the specified solutions: there exists a (limit) Lipschitz function 𝐴 ( 𝑡 ) such that, for any positive 𝑡 , the generalized spherical mean of the solution tends to the specified Lipschitz function as the radius of the sphere tends to infinity. The generalized spherical mean is constructed as follows. First, we apply a monotone function to a solution; this monotone function is determined only by the coefficient at the nonlinearity (both in regular and singular cases). Then we compute the mean over the ( 𝑛 − 1)-dimensional sphere centered at the origin (in the linear case, this mean naturally is reduced to a classical spherical mean). To construct the specified monotone function, we use the Bitsadze method allowing us to express solutions of the studied quasilinear equations via solutions of semi-linear equations.
The validation of the Gifted Rating Scales–School Form in Saudi Arabia

ABSTRACT The current study investigates the reliability and validity of a Saudi-translated version of the GRS-S on a sample of 1,200 Saudi elementary and middle school students. Results showed that the reliability and validity of all six of the GRS-P subscales were high. The results revealed that there were no differences between males and females in all subscales except the leadership scale. There were no differences according to grade level. The current study supports the development of a Saudi-translated version of the GRS-S. The researcher recommended using the rating scale as a screening tool in Saudi Arabia to help gifted students.
Hybrid learning, blended learning or face-to-face learning: which one is more effective in remediating misconception?

Purpose This study aims to investigate the effectiveness of hybrid learning, blended learning and face-to-face learning in remediating misconceptions among primary school teacher education students. Design/methodology/approach This research uses a quasi-experimental design, using a quantitative approach. Data were collected from 99 students using a pretest and posttest four-tier test. Findings Hybrid learning proved to be the most effective, achieving a remarkable 90.32% success rate in remediating students’ misconceptions, surpassing blended learning and face-to-face learning methods. Research limitations/implications The data come from a single Indonesian university and focuses only on a science concept; therefore, the scope of findings may be limited. Practical implications The research suggests that applying the conceptual change (CC) model in all learning types, particularly hybrid learning, effectively remediates misconceptions. Educators can use this insight to design impactful teaching strategies that combine online and traditional components, accommodating diverse learning styles and needs. Social implications This research suggests that applying CC model in all learning types is actually able to remediate misconceptions, though hybrid learning is found to be the most effective one. Originality/value This study addresses a research gap by investigating the effectiveness of different learning modes in rectifying misconceptions. Although prior studies have explored learning modes, few have directly compared hybrid, blended and face-to-face learning in correcting misconceptions. The findings offer insights for effective teaching strategies to address STEM-related misconceptions, benefiting educators in optimizing their approaches. Furthermore, the study’s implications extend to the broader academic community, contributing to evidence-based teaching practices in science education and the development of effective strategies for addressing misconceptions in STEM courses.
A Flexible Multiband Dendritic Structure Fractal Antenna for 4G/5G/WLAN/Bluetooth Applications

In this study, a flexible multiband fractal antenna mimicking dendrite structure is proposed and designed by combining bionics and fractal theory. The dendritic structure of neurons is extracted and simplified into a simple and clear geometric structure. The initial antenna model is obtained by fractal operation on the geometric structure, and finally, four effective bands are obtained. The antenna is printed on a 50 ∗ 70 ∗ 0.1 mm3 polyimide dielectric board and fed by a coplanar waveguide. This paper discusses the effect of the human body on the performance of the antenna and the robustness of the antenna in the bending regime. The gain, efficiency, and cross-polarization of the antenna were tested using a microwave anechoic chamber. The measured antenna covers 1.37 GHz-1.93 GHz (relative bandwidth 35%), 2.25 GHz-2.51 GHz (relative bandwidth 10.7%), 3.13 GHz-3.81 GHz (relative bandwidth 19.3%), and 4.46 GHz-5.5 GHz (relative bandwidth 21.1%) four operating frequency bands. The maximum gain is 6.05 dBi and the maximum efficiency is 91.05%. The antenna can be used for Bluetooth WLAN (Wireless Local Area Network), 4G (4th Generation Communication System), 5G (5th Generation Mobile Communication System), WiMAX (Worldwide Interoperability for Microwave Access), etc. The test results are in good agreement with the simulation results, which proves that the antenna can meet various wireless communication requirements.

Tese (Doutorado em Ciências – Ciências de Computação e Matemática Computacional) – Instituto de Ciências Matemáticas e de Computação, Universidade de São Paulo, São Carlos – SP, 2023. This study aims to increase the use of medical data and the ability to automated diagnosis through the integration and homogenization of the databases from the SI3 Health Information System of the Heart Institute (InCor / HC.FMUSP), and investigate the application of state-ofthe-art machine learning models known as Deep Learning, assessing the potential of Deep Learning to computerized diagnosis. As results, a database was prepared for clinical research in the OMOP-CDM format, called InCor-CDM. In the second study we obtained up to 91% overall accuracy in the classi cation of cutaneous lesions using a deep convolutional neural network on the ISIC database of dermatoscopic images. In the third paper we improved the segmentation of heart magnetic resonance images, on average, by 1.7% in the Dice metric and 2.5x in the training speed of a U-Net convolutional neural network using a localization algorithm. These results demonstrate steps of data preparation; deep learning applied to high-level medical concepts — multi-classi cation for diagnosis; and deep learning applied to low-level image data – Cardiac MRI image segmentation.
Ultraviolet A Combined with Narrow-Band Ultraviolet B is an Effective Treatment Modality for Early Folliculotropic Mycosis Fungoides and Early Mycosis Fungoides Refractory to Narrow-Band Ultraviolet B: A Retrospective Cohort Study

Background. Psoralen plus ultraviolet A (PUVA) is the preferred phototherapeutic modality for early-stage folliculotropic mycosis fungoides (FMF), and for early-stage non-FMF refractory to narrow-band ultraviolet B (NBUVB). However, PUVA has a problematic safety profile. Literature on the treatment with the combination of UVA and NBUVB for MF is sparse. Objective. To evaluate the effectiveness of UVA combined with NBUVB for early-stage MF, specifically for FMF and NBUVB-refractory non-FMF, in adult and pediatric patients. Methods. A retrospective analysis was conducted for patients treated with UVA combined with NBUVB at our center, during 1/2008–8/2022. Results. The cohort included 51 patients: 35 adults and 16 pediatric patients. The overall response rate (ORR) of 39 patients with early-FMF (25 adults and 14 children) was 95%, and the complete response (CR) was 62%. No significant differences in ORR/CR rates were noted between adult and pediatric patients. Of 12 patients with non-FMF (10 adults and 2 children), the ORR was 83% and the CR was 50%. In 17 patients (8 FMF and 9 non-FMF), prior NBUVB therapy resulted in partial response/stable disease; yet, UVA + NBUVB led to CR in 9 patients (4 FMF and 5 non-FMF). Side effects were minimal. Conclusion. Combined UVA and NBUVB is a good alternative to PUVA for adult or pediatric patients with early-stage MF , with FMF or non-FMF refractory to NBUVB.
The complexities of treating brain and spinal cord tumors: a review of current approaches

This article provides an overview of brain and spinal cord tumours, including their types, diagnosis, and treatment approaches. Brain and spinal cord tumours are complex and can be caused by various factors. They can be divided into two main categories, primary and metastatic tumours, which present their own unique challenges and complexities when it comes to treatment. Diagnosing brain and spinal cord tumours requires a careful evaluation of the patient’s medical history and symptoms, as well as a variety of diagnostic tools and techniques. Treatment approaches include surgery, radiation therapy, and chemotherapy, each with its own benefits and drawbacks. The choice of treatment depends on the type and location of the tumour, as well as the patient’s individual needs and preferences. Despite advances in treatment, there is a pressing need for further research to improve the effectiveness and safety of these treatments.

Integration of foot massage and diabetic foot gymnastic on peripheral perfusion in patients with diabetes mellitus 2

The prevalence of Type 2 Diabetes Mellitus (DMT2) is increasing yearly. Peripheral neuropathy of the foot is a complication that often appears in people with diabetes. Neuropathy disorders that are not treated properly can risk causing diabetic ulcers and even amputations. Complementary therapies that can be done to overcome this are foot massage and diabetic foot exercises. Â This study aims to determine the effect of integrating foot massage and diabetic foot gymnastics to overcome complaints of peripheral tissue perfusion in the feet of DMT2 patients at the Polyclinic of Panti Nugroho Hospital. Quasi-experimental research method with Pretest-Posttest Control Group Design design. The intervention and control groups each consisted of 15 respondents. Â The intervention group was given foot massage treatment and diabetic foot exercises for three consecutive days for 15 minutes. The independent t-test and Mann-Whitney test were used to analyze the data. There were significant differences in ABI scores, oxygen saturation, and monofilament scores in the intervention group's left and right legs against the control group (p-value < 0.05). There is a significant effect of the integration of foot massage and diabetic foot gymnastics on peripheral tissue perfusion in both the left leg and right foot of T2DM patients. The contribution of this study needs further research with a larger number of respondents and a longer time to ascertain its effectiveness before it is used as part of local nursing intervention standards.
Effect Of Family Ownership In The Relationship Between Corporate Governance Mechanism And Earning Management

Financial statements are the basis for many parties' decision-making in describing the condition of a company, so companies must present the quality of the information therein. This study examines the relationship between corporate governance mechanisms and earning management and how family ownership influences this relationship. This empirical study uses companies on the Kompas 100 index from 2015 to 2019 to be tested using Generalized Least Squares(GLS). This study finds that the board of commissioners affects earnings management, and family ownership strengthens the role of the board of commissioners in suppressing earnings management. This study strengthens the literature on family ownership in companies. Internal auditors can consider the implication of increasing the effectiveness of internal audits to produce more accurate quality financial reports. In addition, the implications of this study also recommend restructuring the internal audit function, especially its role in management and governance, to be more objective and also impartial.
Aboriginal and Torres Strait Islander employment provisions within enterprise agreements in Australian universities, the role of the National Tertiary Education Union and collective bargaining

Collective bargaining is the foundation for democracy in the workplace, and a mechanism for ensuring workers in Australia have improved working conditions whilst striving to reduce inequality. Collective bargaining offers potential to improve democratic workplace participation and socio-economic status of Aboriginal and Torres Strait Islander peoples, however, if done ineffectively can further entrench inequality. Aboriginal and Torres Strait Islander workplace issues need to be at the forefront of bargaining. In the Higher Education sector, collective agreements with universities cover the majority of employees and are negotiated by the National Tertiary Education Union (NTEU). The NTEU uses its bargaining power within the university sector to establish Aboriginal and Torres Strait Islander employment targets and other targeted provisions within enterprise agreements. These targets and other provisions aim to increase Aboriginal and Torres Strait Islander representation on campus, ensure fair and equitable working conditions and challenge entrenched inequality for Aboriginal and Torres Strait Islander workers within their universities. The NTEU has for over 20 years advocated for and won Aboriginal and Torres Strait Islander employment clauses in enterprise agreements. The National Aboriginal and Torres Strait Islander Policy Committee, under the direction of the Aboriginal and Torres Strait Islander members has pushed for these for the benefit of all Aboriginal and Torres Strait Islander peoples employed or yet to be employed in the higher education sector. The increase in Aboriginal and Torres Strait Islander employment in universities has and continues to be driven by NTEU.
Risk assessment to demonstrate freedom of highly pathogenic avian influenza (HPAI) in Timor Leste

The highly pathogenic avian influenza (HPAI) virus was the cause of a pandemic of avian influenza which affected poultry from most parts of the world. In contrast to most Southeast Asian countries where HPAI is endemic, Timor Leste is currently free from HPAI. The current study was designed to collect data to confirm that Timor Leste is actually free from HPAI and to identify potential risk factors that might be involved in the introduction of HPAI into the country. Data to confirm freedom were collected from various sources, and included biological samples for HPAI testing from regions with a high risk of infection. The analysis of existing animal health data (2004 to 2006) found that, with the exception of a survey in June 2004, there was no evidence of HPAI being present in Timor Leste. In the survey of June 2004 low titres were found indicating previous exposure to HPAI virus (H5 and H7). As only two serological positive samples were found and there were no reports of outbreaks of clinical disease typical of HPAI, it is likely that the results were false positives. As no surveys had been undertaken in Timor Leste since March 2006, as part of the current study, targeted surveillance was conducted in July 2009. As all samples were negative the findings support the belief that Timor Leste was free from HPAI at the time of sample collection. Although the country may currently be free from HPAI, the country is at risk of having an incursion of HPAI through certain high risk practices. These include the smuggling of live chickens, the lack of awareness of HPAI by farmers, a lack of adoption of biosecurity measures by households owning poultry and the extensive poultry management system adopted. A risk assessment that was conducted as part of this study demonstrated that the probability of entry of infection through a smuggled chicken was high. The most important factors that would contribute to the entry of HPAI included: an increased number of chickens smuggled; increased number of smugglers; and the prevalence of AI in Nusa Tenggara Timur (NTT). On the other hand the risk decreased by: strengthening the detection, confiscation, and submission of smuggled birds by the Border Police Units (BPU) and by increasing the destruction of smuggled poultry by quarantine staff. Although there were many putative risk factors identified for HPAI, it was confirmed that Timor Leste was free from HPAI, however the control measures to prevent the introduction of HPAI into the country should be reinforced and target the most influential factors identified in this project.
