Subgroup discovery is a data mining technique which extracts interesting rules with respect to a target variable. An important characteristic of this task is the combination of predictive and ...descriptive induction. An overview related to the task of subgroup discovery is presented. This review focuses on the foundations, algorithms, and advanced studies together with the applications of subgroup discovery presented throughout the specialised bibliography.
Resumen El objetivo fundamental perseguido en este trabajo fue el de conocer los predictores del Miedo y las Habilidades Sociales, así como las relaciones existentes entre ambos de alumnos de 12 a 18 ...años, en la ciudad de Ceuta. Para ello se contó con 557 participantes, de 4 institutos distintos, que reflejan las características del contexto pluricultural de la ciudad. De ellos el 54.2 % fueron chicas, mientras que el 45.8 % fueron varones. El 64.5 % pertenecían a la cultura/religión musulmana, mientras que el 35.5 % eran cristianos. Como instrumentos de evaluación se emplearon la adaptación de Ascensio, Vila, Robles-García, Páez, Fresán y Vázquez (2012) del Inventario de Miedo para Niños (FSSC-II), junto con la EHS (Escala de Habilidades Sociales, Gismero, 2000). Los resultados reflejan niveles medio-bajos de Miedo y medio-altos en las Habilidades Sociales. Las Habilidades Sociales sólo se encuentran bajo la influencia de las variables sociodemográficas Género y Cultura. En el Miedo los predictores son el Género y la Cultura/Religión. Existe relación entre Miedo y las Habilidades Sociales, aumentado estas últimas a medida que descienden las puntuaciones en Miedo.
The purpose of the ASES study is to determine the clinical characteristics of Spanish asthmatic patients seen in primary care (PC) and in pneumology (P) departments, comparing the availability of ...diagnostic methods, morbidity, the type of treatment and follow-up between the two health care settings. ASES is a multicenter, descriptive, cross-sectional study. The physicians were selected by random sampling. The data were collected by the participating physicians using three questionnaires. Data were collected on 2349 asthmatic patients (1298 from hospitals and 1051 from PC). Smokers predominated in the PC setting (
P=0.000). The spirometry was performed at least once a year in 87.2% of the patients seen in P and 39.8% in PC (
P=0.000). Morbidity was high in both groups (P and PC), more than two nighttime awakenings per month (25.5% versus 29%) and emergency visits in previous year (26% versus 21%). A high percent of asthmatic patients was using both inhaled corticoids and long-acting
β
2-agonists (49.5% versus 32%). The 30% of PC patients could not be classified into any step of the treatment. In Spain, the morbidity of disease is high, despite the large use of drugs. Objective monitoring tests have very limited use in PC.
