Se presenta un estudio etnobotánico en el territorio andino limítrofe entre la I Región y II Región de Chile, área que, históricamen-te, ha funcionado como un enlace entre diversas culturas andinas. Para la flora consultada (146 taxa), se registraron 384 vernáculos, correspondiendo el mayor porcentaje a las lenguas aymara-quechua (70% de los nombres). El 90% tenía utilización, registrándose un total de 228 usos, distribuidos en forrajes (36%), medicinas (31%) y comestibles (10%). Se registra: (a) Predominio de vernáculos aymara-quechua y etnocategorías, preferentemente, de acuerdo a la nomenclatura de la I Región; (b) Etnoclasificaciones con hasta tres niveles jerárquicos; (c) Frecuente uso del principio de opuestos complementarios, tanto en los criterios de distinción de especies como en los procedimientos terapéuticos de la flora; (d) Especies ceremoniales similares a las usadas en el extremo norte de Chile, Bolivia y Loa Superior; (e) Heterogeneidad dentro del territorio estudiado, entre las comunidades del área de Ollagüe y las residentes en el Oasis de Pica, tanto en las especies ceremoniales como en los nombres vernaculares. Estos rasgos destacan al área de estudio como transicional, entre las culturas del altiplano de la Región de Tarapacá y las de quebradas altas, de la Región de Antofagasta.Palabras claves: Etnobotánica andina, norte de Chile, transición cultural. Historically, the Andean territorial boundary between Regions I and II of Chile has functioned as a link between diverse Andean cultures. Here, we present an ethnobotanical study from this region which indicates that for the consulted flora (146 taxa) we registered 384

Objective: To monitor coverage and outcomes associated with the activities of the integrated protection system for early childhood Chile Grows with You (CHCC), which includes the comprehensive psychosocial development of children between 18 months and 3 years old, in each of the 29 Health Services of the country, as well as the changes observed after 4 years. material and method: Database analysis of all local public networks in the country between 2008 and 2011 was performed. The application of the test regarding psychomotor development, prevalence of development delay and risk, participation of mothers in educational workshops, home visits and recovery rate of deficient children by age were studied. Median and observed changes of each indicator were analyzed developing a ranking based on the results observed. results: Approximately 75% of children were evaluated, with a prevalence of delay or risk of about 5% and a rate of recovery close to 50%. The participation of mothers in educational workshops increased from 7.6 to 11.0% (p <0.001) and home visits to developmentally delayed children increased 6 times between 2009 and 2011 (p <0.001). Most changes were positive, although the prevalence of developmentally delayed children under 2 years slightly increased (0.6%), and the recovery of 3 year olds decreased (-14.4%). A great variability was observed among the Health Services. Conclusions: There are some positive results in relation to psychomotor development, with significant regional differences. A lower than expected deficit rate regarding psychomotor development was observed, which implies the need to further analyze the instrument used or the conditions of application.
