ABSTRACT:
In Mexico, the estimated Maternal Mortality Ratio is 34.6 deaths per 100,000 estimated births. Consequently, healthcare facilities and services have given precedence to prenatal care, childbirth services, and postpartum care.

In Mexico, the Ministry of Health maintains an open database concerning maternal deaths, encompassing 58 variables. Among these variables is the CIE (International Statistical Classification of Diseases and Related Health Problems), which covers a total of 248 diseases linked to maternal deaths.

Currently, there is no software that classifies women undergoing pregnancy check-ups (according to their socio-clinical risk of mortality), using variables selected with data science.

This project is rooted in the methodology advanced by International Business Machines (IBM) for the implementation of data science.

The software's utilized model was constructed through the Naïve Bayes supervised learning algorithm, yielding an accuracy of 0.7236. The overall precision stood at 0.75, with an overall recall of 0.74, and an overall F1-score of 0.71. For the eclampsia during labor class, precision reached 0.71, recall was 0.94, and the F1- score attained 0.81. As for secondary or late postpartum hemorrhage, precision scored 0.81, recall measured 0.43, and the F1-score was 0.56.

ABSTRACT:
Design thinking is considered to be a positive social psychology intervention. Students who practice using the design thinking process during their coursework will most likely solve personal problems that improve their well-being. This study investigates the impact of using the design thinking process in interdisciplinary courses to enhance students’ well-being through developing mindsets that enable them to solve their problems and set personal goals unconsciously. A modified PERMA-PH model is used to guide this study. The PERMA included Positive Emotions, Negative Emotions, Engagement, Relationship, Meaning and Purpose, and Accomplishments, the “PH” (future plans and health) was added to the PE to ensure continuity of students’ capability in improving their well-being. The participants (n=38) were undergraduate female students (preservice teachers) at a Federal University in the United Arab Emirates (UAE). A sequential mixed-method approach using quantitative and qualitative data was used. An online survey with closed-ended items was adopted to collect data from participants. The qualitative data were collected using semi-structured interviews with six students. The study’s results reveal that students improved their well-being when engaged in the design thinking process during their reflection in the interdisciplinary courses, and expectations of continuing to improve their well-being occurred.

ABSTRACT:
Zero-trust security is a new security model that has recently received much attention. Since the model protects all resources, continuous authentication and authorization of resources are mandatory. Many enterprises currently use cloud systems to manage their resources and provide service. On the other hand, IoT systems typically require cooperation service among IoT devices. As a solution for redundant routes and load on the cloud, a peer-to-peer type system is a good candidate. On the contrary, it requires zero-trust security because each device should guarantee security. Since the authors have proposed and developed CYber PHysical Overlay Network over Internet Communication (CYPHONIC) as a fundamental technology to realize zero-trust security, this paper introduces Public Key Infrastructure (PKI) into CYPHONIC. It proposes an extended device authentication scheme and a key exchange mechanism using digital certificates. According to the PKI mechanism, a certification authority authenticates the system and its authenticity of system, allowing communication with the correct communication partners. The proposed extension performs mutual authentication with digital certificates at the start of communication and secure encryption key exchange for communication between endpoints. We develop the proof of concept of the proposed scheme to confirm the adequacy of the extended mechanisms.

ABSTRACT:
Flexible Electrochromic Organic Nanofilms (FEON) have drawn intense attention due to their advantages over competing technologies. The method utilized to deposit as well as to integrate solutions and processed materials, manufacturing electrochromic organic nanofilms by the Electrodeposition System, has been presented in this research. The FEON device constructed in this work is electrochromic device are the base Poly (3,4-ethylenedioxythiophene), PEDOT:PSS, Poly(3-hexyl thiophene, P3HT, Phenyl-C61-butyric acid methyl ester, PCBM, Vanadium Pentoxide, V₂O₅, Lithium Perchlorate, LiClO4 in Propylene Carbonate, PC and Polyaniline-X1, PANI-X1, that were deposited in Indium Tin Oxide, ITO, and characterized by Electrical Measurements and Scanning Electron Microscopy (SEM). In addition, the thin film obtained by the deposition of PANI, prepared in perchloric acid solution, was identified through PANI-X1. The maximum process temperature was 50°C, which corresponds to the baking of the active polymeric layer. The result obtained by electrical Measurements has demonstrated that the PET/ ITO/PEDOT:PSS/P3HT:PCBM-Blend/V₂O₅/LiClO₄/ PANI-X1/ITO/PET layer presents the characteristic curve of standard electrochromic organic device after spin-coating and electrodeposition. The Thin film obtained by electrodeposition of PANI-X1 on ITO/PET Blend was prepared in perchloric acid solution. The spectrum absorption in the spectral region of 200-1100 nm of the flexible electrochromic organic nanofilm device indicated that the gradual increase of ddp of 0.0 Volt to 5.0 Volt generates a greater deviation in the optical spectral region between 450-850 nm. The thermal effects from ultraviolet irradiation under the device’s surface, in the irradiation simulator chamber, demonstrated a 5% reduction in the device’s lifetime. The inclusion of the PANI-X1 layer reduced the effects of degradation these electrochromic organic nanofilms induced for solar irradiation, a fact that also observed in the irradiation in the simulation chamber. In Scanning Electron Microscopy (SEM) these studies reveal that the surface of PANI-X1 layers is strongly conditioned by the surface morphology of the dielectric.

ABSTRACT:
Despite the available modern technologies, we live in a “fragmented” healthcare system, in which data is stored in multiple sources and a variety of formats and standards without direct communication. However, in the upcoming years, interoperability is emerging, defined as the ability of different information systems, devices, or applications to connect within and across organizational boundaries to access, exchange, and cooperatively use data amongst physicians and patients. We conducted our study using two databases, PubMed and Web of Science, to explore Fast Healthcare Interoperability Resources (FHIR) standard and how we can use FHIR technology to improve interoperability and exchange data between different hospital services. We also expect to find purposes for further research.

ABSTRACT:
Disinformation campaigns can have real and lasting effects, such as driving political elections, causing vaccine hesitancy, and creating intergroup conflicts. This paper reviews existing literature on disinformation and misinformation, and describes a study conducted by the authors in which the likelihood of sharing misinformation was measured among participants who received training based on rules or mindfulness, or who received no training at all. Participants who received misinformation training were less likely to share (i.e., pass along) the misinformation compared to participants who did not receive misinformation training. Thus, susceptibility to misinformation can be combated through educational strategies.

ABSTRACT:
The focus of this research was to analyze current methods for online education for electrical and computer engineering undergraduate programs. From this research, an online model for virtual labs in undergraduate engineering is introduced. Experiential learning was exhibited by students through the hands-on experience with lab equipment combined with user feedback. Software used in this research to simulate traditional lab equipment affords institutions the opportunity to provide instructive methods to remote students who are unable to complete on-campus curricula. The devices used to remotely complete the virtual labs facilitated high-value lab practices and skills comparable to those presented in an on-campus lab. As examined during this research, the opportunity to operate virtual devices with the simulation software delivered an extensive laboratory experience with the capability to create a teaching method for engineering concepts. Data from the students’ feedback on the simulated, interactive learning is presented in this paper.

ABSTRACT:
The aim of this study was to map the access, use and appropriation of Information and Communication Technologies (ICT) by K-12 teachers in the city of Guarujá, on the coast of the State of São Paulo, Brazil. The investigation was carried out throughout the distance training workshops and distance learning activities offered by the Research Center for New Communications Technologies Applied to Education from the University of São Paulo – School of the Future-USP. An Innovation Ecosystem in Basic Education program was conceived in order to conduct the activities and needed to be adapted to fully digital circumstances due to the global COVID-19 emergency in 2020 and 2021. This change ended up allowing the collection of important information about teachers' perceptions of their digital competences. Among the results pointed out, activities started to be carried out digitally, including by non-conventional means, such as through social networks and also mediated by cell phones; the mandatory experience with the digital environment made the teachers understand that it will not be possible to return to a relationship of certain distance with the computational resources. This scenario makes recurrent difficulties even more serious, such as lack of technical support and maintenance, low Internet connection speed and pedagogical support for creating class content with computers.

ABSTRACT:
With the emergence of IoT, new computing paradigms have also emerged. Initial IoT systems had all the computing happening on the cloud. With the emergence of Industry 4.0 and IoT being the major building block, clouds are not the only solution for data storage and analytics. Cloudlet, Fog Computing, Edge Computing, and Dew Computing models are now available, providing similar capabilities as the cloud. The term cloudlet was introduced first in 2011, but research in this area has picked up only over the past five years. Unlike clouds, which are built with powerful server-class machines and GPUs, cloudlets are usually made using simpler devices such as SoCs. In this paper, we propose a complete novel distributed architecture for cloudlets, and we are also proposing algorithms for data storage and task allocation across various nodes in the cloudlet. This cloudlet system was built using Qualcomm Snapdragon 410c. We have analyzed the architecture and the algorithm for varying workloads, bandwidth and data storage. The primary aim of the algorithm and the architecture is to ensure uniform processing and data loads across the nodes of the system.

ABSTRACT:
The bumping movement of the cell flowing over an oblique microgroove was analyzed in vitro. The micro flow-channel (0.05 mm high, 1 mm wide, 25 mm long) with rectangular grooves (4.5 μm deep, 0.2 mm long) was manufactured of polydimethylsiloxane (PDMS) by micromachining technique. The angle between the main flow direction and the longitudinal axis of the groove was 45 degrees. Three groove widths (0.03 mm, 0.04 mm, and 0.05 mm) were studied. Mouse myoblasts (C2C12 cell line) were used in the test. The bulk flow velocity (0.5 mm/s < v< 3 mm/s) of the medium was controlled by the pressure difference between the inlet and outlet. The centroid of each cell was tracked in a movie recorded by the camera attached on the eyepiece of the microscope. The experimental results show that the cell changes direction when passing over the oblique groove. The magnitude of the change depends on the flow velocity of the cell and on the width of the groove. The micro flow-channel with microgrooves has potential to be applied to sorting cells.

ABSTRACT:
This article discusses scientific issues and evidence regarding the policing intelligence-led model (ILP) in police institutions and its applicability in the organizational reality of the Military Police of Santa Catarina (PMSC). This is a theoretical-analytical study with a qualitative approach through a systematic and narrative review of national and international academic production. The research on the subject was found to be incipient in the Brazilian scenario, although space has been gained in several other countries, with a reasonable number of studies. The adoption of intelligence-led policing has the power to "unify" police work, enhance preventive action in public safety, and improve the strategic management of police organizations.
