Sistema de mejora de la extracción de esqueletos de Kinect mediante el algoritmo YOLO

[ES] Kinect es el dispositivo más empleado para la extracción de esqueletos a partir de imágenes de personas en movimiento. Sin embargo, la inexactitud de los datos que proporciona limita la calidad de los estudios que se basan en Kinect. Numerosas líneas de investigación tratan de encontrar un método que mejore la exactitud y utilidad de los datos que proporciona el dispositivo. Este trabajo presenta el uso conjunto y personalizado de DepthYOLO y Decision Maker como método alternativo de extracción de esqueletos basado en deep learning y a partir de la información que ofrece Kinect. Los resultados indican una clara mejoría respecto a los resultados brutos que ofrece Kinect si bien existe margen de mejora, sobre todo en el procesamiento que hace Decision Maker[EN] Kinect is the most used device for skeleton extraction from images of people in motion. However, it renders inaccurate data that limit the quality of research based on Kinect. Many lines of research try to find a method which improves the accuracy and usability of Kinect data. This work explores the use of DepthYOLO and Decision Maker in a joint and customized way as an alternative method of skeleton extraction based on deep learning applied to the information provided by Kinect. Results show a clear improvement of accuracy in skeleton extraction compared with raw data provided by Kinect, but there is still room for improvement especially regarding data processing made by Decision Maker.Martínez Cebrián, H.

The therapist's rule-like verbalizations throughout the clinical process

Se ha reconocido la importancia de las reglas del cliente para explicar un problema psicológico y para lograr superarlo. Sin embargo, no se ha incidido en el papel que podrían tener las reglas del terapeuta en el proceso clínico. Como un primer paso para poder dar una respuesta al respecto, en este estudio realizamos un análisis morfológico de las verbalizaciones en forma de regla emitidas por el terapeuta a lo largo del proceso clínico con el fin de identificar un patrón de emisión de este tipo de verbalizaciones que cambie de acuerdo con los distintos momentos de la terapia. Se analizaron las verbalizaciones en forma de regla emitidas por 9 terapeutas a lo largo de 19 casos clínicos (92 sesiones). Las verbalizaciones se codificaron de acuerdo con un Sistema de Categorización de las Reglas del Terapeuta (SISC-REGLAS-T). Los resultados mostraron diferencias entre el tipo de verbalizaciones en forma de regla y el objetivo que el terapeuta persigue alcanzar en los distintos momentos de la terapia. Estos resultados pueden ayudar a comprender cómo el terapeuta utiliza las verbalizaciones en forma de reglas, lo que contribuye al esclarecimiento del papel de las reglas que emite el terapeuta para conseguir el cambio clínicoIt has been pointed out the importance of the rules to explain and to treat psychological problems. However it hasn’t emphasize the role that the therapist’s rules could have in clinical process. As a first step to give an answer, we realize a morphological analysis of verbalizationlike-rule emitted by the therapist throughout the clinical process with the aim to identify a patron of emission of this kind of verbalization that changes according to different moments of therapy. This study analyzed the verbalization-like-rules emitted by 9 therapists over 19 clinical cases (92 sessions). The verbalizations were coded according to a system of categorization of the Rules Therapist (SISC-RULES-T). The results showed differences between the type of verbalizations-like-rules and target the therapist aims to achieve at different times of therapy. These results may help to understand how the therapist uses this kind of verbalizations, helping to clarify the functional role of rules issued by the therapist for clinical chang

Repeatability and Reliability of the Rheumatoid Arthritis Foot Disease Activity Index in Spanish Patients : A Transcultural Adaptation

The Rheumatoid Arthritis Foot Disease Activity Index (RADAI-F5) questionnaire, based on five questions, is used to assess the severity of rheumatoid arthritis disease in the foot. Nowadays, RADAI-F5 has been validated in different languages; however a Spanish version was lacking. Therefore, the purpose of this research was to translate and validate the Spanish version (RADAI-F5-es). Methods: A cross-cultural translation of the RADAI-F5 questionnaire was performed from English to Spanish. To validate its use, 50 subjects with rheumatoid arthritis who responded to the translated questionnaire two times in an interval of less than 3 months were selected in order to verify the psychometric properties. Results: Excellent agreement between the two versions according to the Cronbach's α was shown. Five domains with regards to arthritis activity in foot joint tenderness and swelling, foot arthritis pain, general foot health and joint stiffness were added together to obtain the total score. Excellent retest reliability was shown for the total score. Test/retest reliability was excellent for joint stiffness on awakening and foot arthritis pain domains. There were no significant differences among any domains (p > 0.05). There were no statistically significant differences (p = 0.000) for the mean ± standard deviations (SD) between pre- and post-tests (98.09 ± 15.42) [93.75-102.43] and 97.96 ± 13.88 [94.5-101.86] points, respectively). Bland-Altman plots or clinically pertinent variations were not statistically significantly different. Conclusions: The RADAI-F5-es is considered a valid and strong tool with adequate repeatability in the Spanish communit
