Innovación para incrementar la adherencia en pacientes crónicos de cardio metabolismo
Get PDF"Existe una amplia variedad de enfermedades crónicas para las cuales se aplican tratamientos farmacológicos. Por definición el término crónico indica que los pacientes deben mantener estos tratamientos de por vida para lograr que sus parámetros de salud se encuentren bajo control. El desbalance de estos parámetros dentro de los sistemas del cuerpo humano puede conducir al paciente a enfermedades, graves complicaciones e incluso a la pérdida de la vida.
La medicina moderna emplea gran parte de los recursos existentes en investigación y desarrollo de terapias, pero hasta tanto no se resuelva por completo la complejidad de encontrarlas, existirán recursos empleados en tratamientos que mitiguen los efectos de la enfermedad logrando así mayores expectativas de longevidad, calidad de vida y estado de salud.
Sin embargo, la efectividad de los tratamientos existentes tiene una variabilidad notable, dependiendo de múltiples factores. Uno de los más importantes es la conducta del paciente para cumplir con las indicaciones prescriptas. Cada vez que un paciente las ignora o abandona, se establece que dicho paciente no adhiere al tratamiento.
(...) El trabajo en curso buscará estudiar con mayor profundidad algunos factores sociales a la luz de la teoría de la economía conductual. Esta escuela de pensamiento será el marco teórico para formular estrategias innovadoras que permitan incrementar la adherencia, con intervenciones a medida de cada paciente. El aumento de adherencia se buscará demostrar a través de una investigación de campo, que sirva de apoyo para la ideación de un caso de negocios que resulte rentable y a la medida de un laboratorio farmacéutico en particular, llamado Gador S.A."Tesis en Dirección Estratégica y Tecnológica (maestría) - Instituto Tecnológico de Buenos Aires, Buenos Aires, 202

Modeling and querying sensor networks using temporal graph databases
No full text"Transportation networks (e.g., river systems or road net works) equipped with sensors that collect data for several different pur poses can be naturally modeled using graph databases. However, since networks can change over time, to represent these changes appropriately, a temporal graph data model is required. In this paper, we show that sensor-equipped transportation networks can be represented and queried using temporal graph databases and query languages. For this, we extend a recently introduced temporal graph data model and its high-level query language T-GQL to support time series in the nodes of the graph. We
redefine temporal paths and study and implement a new kind of path, called Flow path. We take the Flanders’ river system as a use case.
Application of material jetting technology for the development of incision and closure surgical devices
No full text"Material Jetting technology has proven to be very useful in the manufacture of parts with a variety of shapes, consistencies, textures, transparencies and colours, and a great diversity of mechanical properties can be achieved, from low hardness elastomers to rigid materials. Applications range from manufacturing parts in limited production runs with bright, colourful designs to be distributed as marketing items to functional prototypes that closely resemble final products. The possibility of creating digital materials with a wide range of mechanical properties by combining resins that polymerize with UV light makes it possible to approach the final properties of a piece that will later be produced on a larger scale with commercial polymers, both thermoplastic and elastomers, through traditional manufacturing processes such as injection moulding, compression moulding or thermoforming. Keeping in mind these advantages, we have used Polyjet technology for the development of incision and closure surgical devices. The prototypes were manufactured using a combination of resins that allow the properties of commercial elastomers, potentially used for the final product, to be approached. The characteristics of the device, the requirements of the prototypes, and the mechanical properties of the combinations of resins that were considered suitable for this application are described. The differences found between the experimental results and the values reported in the data sheets of the digital materials that were used are discussed.
User-centered road network traffic analysis with MobilityDB
No full text"Performance indicators of road networks are a long-lasting topic of research. Existing schemes assess network properties such as the average speed on road segments and the queuing time at intersections. The increasing availability of user trajectories, collected mainly using mobile phones with a variety of applications, creates opportunities for developing user-centered performance indicators. Performing such an analysis on big trajectory data sets remains a challenge for the existing data management systems, because they lack support for spatiotemporal trajectory data. This article presents an end-to-end solution, based on MobilityDB, a novel moving object database system that extends PostgreSQL with spatiotemporal data types and functions. A new class of indicators is proposed, focused on the users' experience. The indicators address the network design, the traffic flow, and the driving comfort of the motorists. Furthermore, these indicators are expressed as analytical MobilityDB queries over a big set of real vehicle trajectories.

Second wave of COVID-19 pandemic in Argentinian population: vaccination is associated with a decrease in depressive symptoms
Get PDF"Since the irruption of the coronavirus disease 2019 (COVID-19) the planet has submerged in a time of concern and uncertainty, with a direct impact on people's mental health. Moreover, the recurrent outbreaks that periodically harry different regions of the world constantly refocus people's concerns to the pandemic. Yet, each new wave heats the diverse countries in different situations, including the advances in their vaccination campaigns. In this research, we studied the levels of the general anxiety disorder (GAD) and depression in the Argentine population across the first and second waves of infections that occurred in our country.
ATR: Template-based repair for alloy specifications
Get PDF"Automatic Program Repair (APR) is a practical research topic that studies techniques to automatically repair programs to fix bugs. Most existing APR techniques are designed for imperative programming languages, such as C and Java, and rely on analyzing correct and incorrect executions of programs to identify and repair suspicious statements. We introduce a new APR approach for software specifications written in the Alloy declarative language, where specifications
are not “executed”, but rather converted into logical formulas and analyzed using backend constraint solvers, to find specification instances and counterexamples to assertions. We present ATR, a technique that takes as input an Alloy specification with some violated assertion and returns a repaired specification that satisfies the assertion. The key ideas are (i) analyzing the differences between counterexamples that do not satisfy the assertion and instances that
do satisfy the assertion to guide the repair and (ii) generating repair candidates from specific templates and pruning the space of repair candidates using the counterexamples and satisfying instances. Experimental results using existing large Alloy benchmarks show that ATR is effective in generating difficult repairs. ATR repairs 66.3% of 1974 fault specifications, including specification repairs that cannot be handled by existing Alloy repair techniques.
