- ItemActivity and posture recognition for the elderly based on a wearable device(2018) Cajamarca, María Gabriela; Herskovic, Valeria; Pontificia Universidad Católica de Chile. Escuela de IngenieríaLa postura humana y los niveles de actividad son indicadores para evaluar la salud y la calidad de vida de las personas. Esta información puede ser monitoreada y utilizada para evaluar parámetros físicos y funcionales. Los cambios físicos por desequilibrio de la columna, pueden ser la causa de dolor de espalda, deterioro neurológico, deformidad, problemas cosméticos, o una combinación de los mencionados. Estos cambios son más comunes en personas mayores. Se han propuesto algunos prototipos que se pueden usar para el monitoreo de cambios en la columna vertebral, sin embargo, no se ha considerado lo suficiente la experiencia del usuario con estos dispositivos, para entender cuáles son las características centrales para el uso a largo plazo. La propuesta de este estudio es diseñar dispositivos portátiles de acuerdo con las condiciones de los ancianos para monitorear la postura de la columna mediante tres sensores adheridos al tronco y evaluar la experiencia del usuario cuando utilizan estos. Primero, diseñamos e implementamos un prototipo llamado StraightenUp para el monitoreo estático de la postura espinal, la evaluación de este diseño fue en personas sanas y jóvenes. Luego, se realiza observaciones sobre características y limitaciones de personas mayores con vida asistida para conocer el ritmo de las actividades diarias. Finalmente, proponemos una versión mejorada de StraightenUp considerando problemas de diseño encontrados en su evaluación. Creamos un nuevo prototipo denominado StraightenUp+. La evaluación de esta nueva versión se realiza en ancianos institucionalizados. Se obtuvo un alto rendimiento del dispositivo, los sensores son lo suficientemente precisos para detectar posturas corporales. Con respecto a la experiencia del usuario con este dispositivo, los participantes lo apreciaron de manera muy positiva, destacan su comodidad, usabilidad y familiaridad con una prenda de vestir. Los hallazgos de este estudio pueden usarse como apoyo hacia una tecnología de monitoreo de posturas de la columna más completa específicamente diseñada para la población que envejece.

- ItemAnálisis de clusters y de trayectorias de motivación de estudiantes de un curso de programación en modalidad remota de emergencia(2022) Jahr Andrade, Andrés Sebastián; Herskovic, Valeria; Muñoz Gama, Jorge; Pontificia Universidad Católica de Chile. Escuela de IngenieríaLa pandemia de COVID-19 trajo consigo consecuencias no solo en el ámbito de salud y económico, sino que también en educación. Las personas se vieron obligadas a cumplir estrictos protocolos sanitarios los cuales implicaron, entre otras cosas, restricciones de desplazamiento y cuarentenas. En consecuencia, sin mas opción, los centros educacionales se vieron obligados a pasar a un formato remoto, modalidad conocida como aprendizaje remoto de emergencia, o emergency remote teaching (ERT). ERT tiene consecuencias para profesores y estudiantes, las cuales podrían afectar la motivación y, por ende, el aprendizaje de estos últimos. Con la finalidad de analizar dicha situación se realizaron 3 encuestas en un curso universitario de programación, las cuales incluían preguntas del Motivated Strageties for Learning Questionnaire (MSLQ), cuestionario autoreporte que evalúa la motivación académica de los estudiantes en distintas escalas; preguntas demográficas y descriptivas, y preguntas respecto a la preocupación por el COVID-19. A partir de lo anterior, se generaron perfiles de estudiantes utilizando el método de clusterización k-means y se analizaron sus diferencias con diversas pruebas estadísticas. Adicionalmente, se generaron trayectorias de motivación considerando los 3 periodos estudiados. A raíz de ello se descubrió la existencia de 4 perfiles de estudiantes. El perfil más adaptativo tuvo una alta motivación, además de verse más preparado y menos frustrado con las condiciones del ERT. Sin embargo, tuvo los niveles mas altos de preocupación por el COVID-19. El perfil menos adaptativo, se comporto en general como un espejo de las variables del más adaptativo, siendo el cluster con mayor representación de mujeres. En lo que respecta a trayectorias, se evidenciaron diversas variaciones motivacionales a través del tiempo. Por último, se mostraron claras diferencias entre las trayectorias de los estudiantes más y menos preocupados por el COVID-19.

- ItemEnabling Older Adults’ Health Self-Management through Self-Report and Visualization—A Systematic Literature Review(2020) Cajamarca, María Gabriela; Herskovic, Valeria; Rossel, Pedro O.Aging is associated with a progressive decline in health, resulting in increased medical care and costs. Mobile technology may facilitate health self-management, thus increasing the quality of care and reducing costs. Although the development of technology offers opportunities in monitoring the health of older adults, it is not clear whether these technologies allow older adults to manage their health data themselves. This paper presents a review of the literature on mobile health technologies for older adults, focusing on whether these technologies enable the visualization of monitored data and the self-reporting of additional information by the older adults. The systematic search considered studies published between 2009 and 2019 in five online databases. We screened 609 articles and identified 95 that met our inclusion and exclusion criteria. Smartphones and tablets are the most frequently reported technology for older adults to enter additional data to the one that is monitored automatically. The recorded information is displayed on the monitoring device and screens of external devices such as computers. Future designs of mobile health technology should allow older users to enter additional information and visualize data; this could enable them to understand their own data as well as improve their experience with technology.

- ItemImproving the initial response process in urban emergencies(IEEE, 2012) Monares, A.; Ochoa, S.; Pino, J.; Herskovic, ValeriaGrowing population and service interconnection make urban areas increasingly vulnerable to emergency situations. Although the firefighting response process plays a key role in most urban emergencies, it has remained essentially unchanged in the past decades; therefore it has several limitations to coordinate effective and efficient response activities. This paper studies the firefighting initial response process in order to measure, understand and improve it. The study involved a literature review, interviews with firefighting personnel and the analysis of 66 urban emergencies in the city of Santiago (Chile). Based on the obtained results this article proposes an emergency coordination system to improve the initial response process in urban emergencies. In order to realize the impact of the proposed system on the initial response process, a simulation based on past emergencies is presented and discussed.
- ItemIncreasing shared information availability during urban emergency responses(IEEE, 2011) Monares, Álvaro; Herskovic, Valeria; Suárez, David; Ibarra, Manuel; Ochoa, Sergio F.; Pino, José A.Firefighters are responsible for dealing with several types of urban emergencies, such as fires, car crashes and explosions. The participants in an emergency response process require shared information to make effective, on-time decisions, and to coordinate their activities. The information sharing process is currently performed using message exchange through a radio system. However, limitations in this communication medium jeopardize information availability during the emergency. This may produce undesirable situations, such as lack of coordination among firefighters or wrong decisions due to lack of supporting information. As a way to deal with the problem, this article proposes a computer-based system, which complements the radio system. The system helps increase the availability of the information that is most frequently requested by firefighters in the field, identified by a study of 65 past emergencies. The results of a preliminary evaluation indicate the solution is able to ensure the availability of at least the 30% of the most requested information during an emergency.
