This paper is the result of an investigation of the flora and traditionalknowledge in the conception of Javaé indigenous people from the Txuirivillage located on Bananal Island, Brazil. The objective is to investigatethe plants used by these indigenous people, their diverse uses and tounderstand how traditional knowledge is passed on to new *** is a qualitative, descriptive and interdisciplinary survey, whose datacollection strategies included the application of semi-structured questionnairesand collection of plants for cataloguing according to AngiospermPhylogeny Group or APG III (2009). We identified 26 plant species, usedfor various purposes such as medicinal use, food, construction, craft andcultural, which were deposited in the Herbarium of the Federal Universityof Tocantins. Roots, stem and leaf are the plant parts most used bythe community. The plants mentioned were most frequently found on thebanks of the Javaés River and in the backyard of the residences. Significanttraditional knowledge of these people about the plants are transmittedto new generations, through visual, orality and experimentation. Ethnobotanicalstudies strengthen research in ecopsychology while allowingresearch into the interactions between human populations and plants.

作者： Ednaldo Antonio dos santos Esperanza Marchant Sanchez maria Angeles Niguez Ortiz maria Amparo Oliver Germes Doctoral Programin Promotion of Autonomy and Social Healthcare in the Unit University of Valencia.

Mental disorders are considerate "the evil of the century" by renowned researchers, because a large part of the population in many countries is a diagnosticated, and currently afect youth and children. Among the numerous therapeutic interventions, the music therapy is a non-invasive approach. However, there are very few people who are professionally engaged in research and studies on the subject. Therefore, this article is a literature to talk about the benefits of music therapy sessions for people with stress, depression and anxiety disorders.

International Journal of Ophthalmology(English edition) 2015年第6期8卷 1156-1161页

作者： Federico Saenz-Frances Luis Janez Lara Borrego-Sanz Clara Berrozpe-Villabona Jose maria Martinez-de-la-Casa Laura Morales-Fernandez Julian Garcia-Sanchez Enrique santos-Bueso Julian Garcia-Feijoo Department of Ophthalmology Clinico San Carlos HospitalComplutense University of Madrid Technology of Knowledge Institute Complutense University of Madrid

AIMTo correlate corneal variables (determined using the Pentacam) with optic nerve head (ONH) variables determined using the Heidelberg retina tomograph (HRT) in healthy subjects and patients diagnosed with primary open angle glaucoma (POAG).METHODSMeasurements were made in 75 healthy eyes and 73 eyes with POAG and correlations examined through Pearson correlation coefficients between the two sets of variables in the two subject groups. The corneal variables determined were corneal volume (CVol), central corneal thickness (CCT), overall corneal thickness (OvCT), the mean thickness of a circular zone centered at the corneal apex of 1 mm radius (zone I) and the mean thickness of several concentric rings, also centered at the apex until the limbus, each of 1 mm width (zones II to VI respectively). The ONH variables were determined using the *** following pairs of variables were correlated in the control group: CCT-disc area (DAr) (-0.48; P<0.0001), Zone I-DAr (-0.503; P<0.0001) and Zone II-DAr (-0.443; P<0.0001); and in the POAG group: CCT-cup-to-disc area ratio (CDRa) (-0.402; P<0.0001), Zone I-CDRa (-0.418; P<0.0001), Zone II-CDRa (-0.405; P=0.006), Zone I-cup shape measure (CSM) (-0.415; P=0.002), Zone II-CSM (-0.405; P=0.001), Zone IV-height variation contour (HVC) (0.378; P=0.002); Zone V-HVC (0.388, P<0.0001).CONCLUSIONSIn the healthy subjects, significant negative correlation was detected between central and paracentral corneal thickness and optic disc area. In contrast, the POAG patients showed significant negative correlation between central and paracentral corneal thickness and the cup-disc ratio and CSM, and positive correlation between peripheral corneal thickness and HVC.
