Occupant action patterns regarding spatial and human factors in office environments
Since occupant behaviour impacts the energy performance of buildings, its study is relevant in order to bridge the performance gap. While the factors influencing occupant behaviour have been established, most studies have focused on those factors that motivate the action, such as environmental and temporal conditions. Contextual factors including spatial and occupant characteristics, which act as action moderators, remain a subject to explore. In this way, this article aims to identify patterns in the occupants’ actions in office environments, based on spatial and human factors. A field study, including 514 occupants in 85 office spaces, was carried out in 11 buildings in Concepción, Chile. The results indicate that spatial layout is significantly related to the operation of windows, blinds, and thermostats, but not personal devices. Gender did not influence whether an occupant was active or not and age range was only significant regarding blinds. In shared spaces, there were fewer active occupants and whose acts depend on the perception of opportunity that they have, which is associated with element control distance and occupant age. The findings suggest that the probability that actions occur varies based on spatial and human factors, particularly because these factors affect occupant perception of opportunity
Do we need complex and multidimensional indicators to assess energy poverty? The case of the Chilean indicator
Energy poverty is a multidimensional and complex phenomenon, and several indicators have been developed to
evaluate and quantify it. However, often greater complexity does not mean greater precision. In the case of Chile,
the Energy Poverty Network established the Three-dimensional and Territorial Indicator of Energy Poverty
(EPTTI in Spanish) to assess the energy poverty situation of Chilean families. The EPTTI is based on a multidimensional
approach with 10 indicators. Although, their evaluation involves resources that may hinder a
practical application. This study analyzed the consistency between the individual responses of an indicator and
the adapted EPTTI evaluation, using a database of 641 families. The results show that the excessive energy
expenditure and the type and energy source of heating systems indicators are the variables with the greatest
influence on energy poverty assessments. These results served to both propose simplified approaches for energy
poverty assessment with the indicator, and establish policies of action that regional governments should address

Domestic hot water consumption prediction models suited for dwellings in central-southern parts of Chile
Domestic hot water (DHW) consumption in dwellings can play a key role in the development of policies that are focused on energy poverty, and in improving energy efficiency, among other aspects. There is an important variability observed with DHW among different countries due to technical, sociological, climatic, and economic factors. Most studies that deal with DHW predictions are based on stochastic models, and only a few apply time series or statistical methods. In the case of Chile, the country is undergoing a policy development process, and there is little information about DHW consumption. As a result, it is fundamental to have DHW consumption prediction models that are focused on dwelling. For this reason, the study analysed the possibility of using time series models to make future estimations about monthly domestic hot water (DHW) consumption. To this end, consumption data obtained from 98 apartments between 2015 and 2021 were used, and 3 approaches were applied namely, exponential smoothing, basic structural model (BSM), and state-space model (SSM). The results showed that exponential smoothing and state-space methods allowed to obtain satisfactory results with regard to percentage error and confidence levels. Therefore, these models could be used to make future estimations of domestic hot water (DHW) consumption
Abuso sexual infantil : protocolos de protección integral en Colombia
Este Trabajo de Grado tuvo como objetivo principal, identificar los protocolos de intervención del Abuso Sexual Infantil (ASI) que cumplen con los requisitos de Protección Integral, según la Ley 1098 de 2006 en Colombia. Para esto se estableció una metodología cualitativa y un diseño interpretativo y comprensivo, lo que permitió hacer uso de la Técnica de Análisis de Contenido en los Protocolos Nacionales e Internacionales. Los resultaron permitieron reconocer la falencia nacional respecto al desarrollo de Protocolos en ASI, a partir de los criterios de Protección Integral establecidos en el Código de Infancia y Adolescencia (Ley Nº 1098, 2006).The main objective of this thesis was to identify the intervention protocols of the Child Sexual Abuse, which meet the Integral Protection requirements, according to the 1098 Law of 2006 in Colombia.

Valoración del estado nutricional por antropometría y bioimpedancia en el ámbito de la fisioterapia
La valoración de la composición corporal es relevante para determinar el riesgo de enfermedades cardiovasculares y metabólicas como también en el seguimiento de adaptaciones morfológicas en fisioterapia deportiva. Lamentablemente, este tipo de valoración se centra especialmente en la determinación de medidas sencillas como el índice de masa corporal (IMC) que ofrece información limitada del estado nutricional. Sin embargo, la implementación de otras herramientas permite un mejor acercamiento a la composición corporal, razón por la cual se han creado metodologías como la bioimpedancia eléctrica y la antropometría que son de bajo costo y fáciles de usar, pero requieren de protocolos de medición precisos con un óptimo manejo de los instrumentos de medición. En este sentido, esta revisión narrativa pretende aportar un marco metodológico para la realización de estas mediciones en la práctica clínica y deportiva para el fisioterapeuta

Fusarium: more than a node or a foot-shaped basal cell
Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an alternate hypothesis, namely a very broad concept of the genus Fusarium was proposed. In doing so, however, a significant body of data that supports distinct genera in Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA phylogeny based on 19 orthologous protein-coding genes was presented to support a very broad concept of Fusarium at the F1 node in Nectriaceae. Here, we demonstrate that re-analyses of this dataset show that all 19 genes support the F3 node that represents Fusarium sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone of the phylogeny is resolved by the concatenated alignment, but only six of the 19 genes fully support the F1 node, representing the broad circumscription of Fusarium. Furthermore, a re-analysis of the concatenated dataset revealed alternate topologies in different phylogenetic algorithms, highlighting the deep divergence and unresolved placement of various Nectriaceae lineages proposed as members of Fusarium. Species of Fusarium s. str. are characterised by Gibberella sexual morphs, asexual morphs with thin- or thick-walled macroconidia that have variously shaped apical and basal cells, and trichothecene mycotoxin production, which separates them from other fusarioid genera. Here we show that the Wollenweber concept of Fusarium presently accounts for 20 segregate genera with clear-cut synapomorphic traits, and that fusarioid macroconidia represent a character that has been gained or lost multiple times throughout Nectriaceae. Thus, the very broad circumscription of Fusarium is blurry and without apparent synapomorphies, and does not include all genera with fusarium-like macroconidia, which are spread throughout Nectriaceae (e.g., Cosmosporella, Macroconia, Microcera). In this study four new genera are introduced, along with 18 new species and 16 new combinations. These names convey information about relationships, morphology, and ecological preference that would otherwise be lost in a broader definition of Fusarium. To assist users to correctly identify fusarioid genera and species, we introduce a new online identification database, Fusarioid-ID, accessible at www.fusarium.org. The database comprises partial sequences from multiple genes commonly used to identify fusarioid taxa (act1, CaM, his3, rpb1, rpb2, tef1, tub2, ITS, and LSU). In this paper, we also present a nomenclator of names that have been introduced in Fusarium up to January 2021 as well as their current status, types, and diagnostic DNA barcode data. In this study, researchers from 46 countries, representing taxonomists, plant pathologists, medical mycologists, quarantine officials, regulatory agencies, and students, strongly support the application and use of a more precisely delimited Fusarium (= Gibberella) concept to accommodate taxa from the robust monophyletic node F3 on the basis of a well-defined and unique combination of morphological and biochemical features. This F3 node includes, among others, species of the F. fujikuroi, F. incarnatum-equiseti, F. oxysporum, and F. sambucinum species complexes, but not species of Bisifusarium [F. dimerum species complex (SC)], Cyanonectria (F. buxicola SC), Geejayessia (F. staphyleae SC), Neocosmospora (F. solani SC) or Rectifusarium (F. ventricosum SC). The present study represents the first step to generating a new online monograph of Fusarium and allied fusarioid genera (www.fusarium.org)
