ABSTRACT Human activities, combined with lack of urban planning, degrade the quality of life and sense of security among individuals. However, what specific aspects of the urban environment are related to the perception of natural disaster risk? Using the Survey method, the study collected information from a sample of 279 homeowners, selected non-probabilistically for convenience. Correlations were examined between subjective perceptions of natural disaster risk and satisfaction with housing and the environment. Additionally, the study investigated the relationship between the sample's socioeconomic profile and perception of natural disaster risk. The results indicated that concern about adverse environmental events negatively influences satisfaction. In the housing context, characteristics such as façade materials, lighting and safety showed an inverse relationship with risk perception. Similarly, urban environment elements such as water supply and sanitation, access to Internet and telephone and cleanliness of public streets and sidewalks showed a negative correlation. Therefore, the quality of neighborhood infrastructure influences how residents perceive their protection against potential natural disasters in the urban environment.

RESUMO As atividades humanas, combinadas à ausência de planejamento urbano, degradam a qualidade de vida e o senso de segurança das pessoas. Contudo, quais aspectos específicos do ambiente urbano estão ligados à percepção de risco de desastres naturais? Por meio da abordagem do método Survey, o estudo coletou informações de uma amostra de 279 proprietários, selecionada de forma não probabilística por conveniência. Foram examinadas as correlações entre as percepções subjetivas de risco de desastres naturais e a satisfação com a moradia e com o entorno. Além disso, o artigo investigou como o perfil socioeconómico da amostra se relaciona com a percepção de risco de desastres naturais. Os resultados indicaram que a preocupação com eventos ambientais adversos influencia negativamente a satisfação. No contexto habitacional, características como os materiais da fachada, a iluminação e a segurança mostraram uma relação inversa com a percepção de risco. Da mesma forma, elementos do ambiente urbano, como abastecimento de água e saneamento, acesso à internet e à telefonia, e limpeza das vias públicas e das calçadas revelaram uma correlação negativa. Portanto, a qualidade da infraestrutura nos bairros interfere na maneira como os residentes percebem sua proteção contra possíveis desastres naturais no ambiente urbano.

RESUMEN En La Yerbabuena, Jalisco, México, destaca una tipología de construcción con base en materiales vernáculos. Las personas de esta comunidad han perdido la costumbre de utilizar este tipo de materiales por pensar que son de baja calidad y reducen el estatus social y económico, por consiguiente, el objetivo de investigación fue indagar sobre métodos constructivos que existen en esta comunidad, para proponer un método constructivo vernáculo que brinde información a los habitantes de este lugar e incitar a que exista el gusto por conservar y construir las viviendas con este método arquitectónico. La investigación que se realizó fue de tipo analítica y propositiva, en el contexto histórico de las viviendas edificadas en La Yerbabuena, de la región de la Sierra de Amula, Jalisco. Como conclusión, se señala que las casas vernáculas que prevalecen en La Yerbabuena tienen de 100 a 120 años de antigüedad y sus usuarios mencionan que brindan confort térmico, acústico, de iluminación y ventilación natural, lo que propicia que recomienden ampliamente este sistema constructivo con base en su experiencia habitable.

ABSTRACT In La Yerbabuena, Jalisco, Mexico, a building typology based on vernacular materials stands out. The people of this community have abandoned the habit of using these materials because they think they are low quality and detrimental to social and economic status. Therefore, the research purpose was to investigate existing construction methods in this community, in order to propose a vernacular construction method that provides information to the inhabitants and encourages them to appreciate and build homes with this architectural method. An analytical and propositional research was conducted, within the historical context of homes built in La Yerbabuena, in the region of Sierra de Amula, Jalisco. In conclusion, it is noted that the vernacular houses prevailing in La Yerbabuena are between 100 to 120 years old. Their users mention that these houses provide thermal, acoustic, and lighting comfort, and natural ventilation, which leads them to strongly recommend this construction system based on their living experience.

RESUMEN El propósito de este artículo es presentar un método para la valoración del patrimonio construido a partir de la relación sol-edificio y divulgar la riqueza arquitectónica del conjunto de edificios de la Universidad del Valle sede Meléndez en Cali. La metodología consta de cuatro fases que emplean procedimientos y equipos de levantamiento, monitoreo ambiental, modelado virtual y análisis bioclimáticos. Este enfoque ofrece una perspectiva alternativa para valorar el patrimonio. En el caso de estudio se encontró un conocimiento profundo de los diseñadores sobre estrategias de iluminación natural y control solar, en el cual se identificó la envolvente como un dispositivo arquitectónico complejo que contribuye tanto a la estética como al confort. La metodología permite combinar enfoques cualitativos y cuantitativos en investigaciones patrimoniales, priorizando la evaluación de la calidad de la iluminación natural y la protección solar, aspectos subestimados en la valoración tradicional del patrimonio. Se destaca la importancia de usar herramientas, técnicas de representación y análisis digital para la comprensión y revaloración de la arquitectura patrimonial.

ABSTRACT The purpose of this article is to present a method for assessing built heritage based on the sun-building relationship and to make known the architectural richness of the buildings at the Universidad del Valle, Meléndez campus in Cali. The methodology consists of four phases employing surveying procedures and equipment, environmental monitoring, virtual modeling, and bioclimatic analysis. This approach offers an alternative perspective for assessing heritage. The case study reveals a deep understanding of designers about natural lighting strategies and solar control, identifying the envelope as a complex architectural device that contributes to both aesthetics and comfort. The methodology allows combining qualitative and quantitative approaches in heritage research, prioritizing the evaluation of natural lighting quality and solar protection, aspects underestimated in traditional heritage assessment. The importance of using tools, digital representation and analysis techniques for understanding and reassessing architectural heritage is highlighted.

Abstract In this article, I review proposed guidelines for the touristic management of micro-territories, to establish the foundation for new neighborhood-oriented planning methodologies (micro-territories). I proposed an exploratory methodology upon which I built the baseline for organizing micro-territories considering three main axes. The first axis is a diagnosis, subdivided into components: tourism, social, and environmental, each with its indicators and evaluations. The information for its construction was gathered through direct observation and information compilation. The second axis corresponds to satellite localization and categorization of micro spaces. These were constructed on Google Earth, based on diagnostic information, and are integral parts of a micro-territory; The third axis consists of strategies for strengthening the micro-territory; in this section, I provide ideas to assist decision-makers in the studied neighborhood. The micro-territory of San Juan, located in Quito’s Oldtown was selected for this study. The results indicate that San Juan’s neighborhood has the potential to develop tourism activities, along with an important social base and good natural diversity. These aspects were reflected in four micro-spaces and the development of various strategies, ranging from public lighting to tree planting in the area. In conclusion, it is reaffirmed that the proposal is feasible; however, aspects such as its scope need to be adjusted, certain evaluation indicators need to be changed, or additional micro-spaces need to be included.

Resumen En el presente artículo se realizó una revisión a la propuesta de lineamientos para el ordenamiento turístico de microterritorios, misma que tenía como fin establecer las bases para una nueva metodología de planificación orientada a los barrios (microterritorios). Para ello se propuso una metodología exploratoria, en la cual se fueron construyendo las bases para el ordenamiento de microterritorios a través de tres ejes principales. Un diagnóstico subdividido en componentes: turístico, social y ambiental, cada uno con sus propios indicadores y evaluaciones. La información para su construcción se recopiló a través de observación directa y compilación de información. El segundo eje es la localización satelital y categorización de microespacios. Los microespacios se obtienen en base a la información del diagnóstico y son partes integrales de un microterritorio, para su construcción se usó Google Earth. El tercer eje son estrategias para el fortalecimiento del microterritorio; en este apartado se brindan ideas que sirvan a los tomadores de decisiones del barrio estudiado. El microterritorio San Juan, ubicado en el Centro Histórico de Quito, fue seleccionado para el desarrollo de la propuesta. Los resultados obtenidos señalan que el barrio San Juan cuenta con potencial para desarrollar la actividad turística, una base social importante y una buena diversidad natural. Estos aspectos fueron traducidos en la creación de cuatro microespacios y la elaboración de estrategias variadas que van desde alumbrado público hasta arborización de la zona. En conclusión, se reafirma que la propuesta es factible; sin embargo, se deben corregir aspectos como la extensión de la misma, cambiar ciertos indicadores de evaluación o aumentar otros microespacios.

RESUMO O estudo aborda o problema das formas de vida em ambientes ecológicos frágeis, como oásis em desertos. Assim, o oásis de San Pedro de Atacama está sofrendo atualmente uma redução em sua área agrícola devido à urbanização e ao turismo, afetando a sustentabilidade das práticas agrícolas tradicionais e colocando em risco o equilíbrio ecológico e cultural dessa paisagem do Atacama. O artigo apresenta estratégias de design sustentável para a vida contemporânea em ambientes frágeis, examinando as qualidades térmicas e as estratégias de controle climático aplicadas ao caso da Casa Taller de Magdalena Gutiérrez, usando os princípios de Lisa Heschong e Eva Horn, incluindo os modos de gestão climática de Reyner Banham. A metodologia empregada combina uma análise arquitetônica e etnográfica, estruturada em três etapas: seleção de obras, construção da estrutura conceitual, análise e sistematização da obra. Modelos, fotografias, mapas e diagramas foram usados para contrastar teorias e qualidades térmicas e culturais com evidências do trabalho. Os critérios de classificação incluíram a avaliação de características como o grau de privacidade de áreas e recintos, ventilação, iluminação, isolamento térmico e métodos de aquecimento, e uma classificação binária foi usada para a avaliação sistemática. Os resultados destacaram que a Casa Taller é uma manifestação de moradia poética na exterioridade do deserto do Atacama, sugerindo uma vocação para atividades comunitárias. As qualidades de iluminação revelaram um projeto estratégico que maximiza a luz natural controlada, usando aberturas e claraboias. Concluiu-se que a casa-ateliê representa uma expressão do “Regionalismo Crítico revisitado”. Nessa abordagem, a relação “local-forma” é fundamental, equilibrando a técnica local com o ambiente cultural e natural. Esse trabalho oferece um modelo sustentável para viver em ambientes frágeis, no qual o projeto arquitetônico é devidamente integrado às condições climáticas e culturais do local.

ABSTRACT This study addresses the issue of living in fragile ecological environments, such as oases in deserts. Currently, the oasis of San Pedro de Atacama is experiencing a decrease in its agricultural area due to urbanization and tourism, affecting the sustainability of traditional farming practices and putting at risk the ecological and cultural balance of this Atacamenian locale. The article presents sustainable design strategies for contemporary living in fragile environments, examining thermal qualities and climate control strategies applied to the “Workshop House” or Casa Taller of Magdalena Gutiérrez. Using the principles of Lisa Heschong and Eva Horn, the review also includes Reyner Banham’s climate management modes. The methodology combines architectural and ethnographic analysis, structured in three stages: selection of works, construction of the conceptual framework, and analysis and systematization. Models, photographs, maps, and diagrams were used to contrast theories and thermal and cultural qualities with evidence from the work. Classification criteria included evaluating characteristics such as the degree of privacy of areas and rooms, ventilation, lighting, thermal insulation, and heating methods, with a binary rating employed for systematic evaluation. The results highlighted that Casa Taller manifests poetic living in the exteriority of the Atacama Desert, suggesting a vocation for community activities. The lighting qualities revealed a strategic design that maximizes controlled daylight, utilizing openings and skylights. It was concluded that the Casa Taller represents an expression of “Revisited Critical Regionalism.” The “site-form” relationship is fundamental in this approach, balancing local techniques with cultural and natural surroundings. This work offers a sustainable model for living in fragile environments, where architectural design is appropriately integrated with the place’s climatic and cultural conditions.

ABSTRACT The light well is an architectural resource used to provide daylighting from the core of the building. It is often designed according to an index without taking into account the influence of each of the architectural variables on the daylighting gains. Therefore, this study aims to identify and compare the influence of these architectural variables on the daylighting performance of a residential light well. For this purpose, a basic model of a six-storey light well in the city of São Paulo, Brazil, was parametrically simulated by varying, in alternative cases, its geometric dimension, the reflectance of its walls and the window opening of the rooms connected to it. The Annual Sunlight Exposure (ASE1000) and Spatial Daylight Autonomy (sDA300/50%) metrics were used to evaluate daylighting, using Climate Studio software. It was observed that increasing reflectance is a solution that improves the distribution of natural light without increasing the level of direct sunlight, while increasing the geometric dimension results in a greater area of direct sunlight in the fountain, not exceeding the fourth floor. To minimize the risk of visual discomfort in the rooms, the windows should be smaller in the upper half and larger in the lower half of the light well. Thus, the variables considered contribute in different ways to increase the daylighting in the evaluated environments, although the risk of visual discomfort must be considered in some cases.

RESUMO O poço de luz é um recurso arquitetônico utilizado para promover iluminação natural a partir do núcleo do edifício. Frequentemente, ele é projetado de acordo com um índice sem levar em consideração a influência de cada uma das variáveis arquitetônicas nos ganhos de iluminação natural. Assim, este estudo tem como objetivo identificar e comparar a influência dessas variáveis arquitetônicas no desempenho da iluminação natural de um poço de luz do edifício residencial. Para isso, foi simulado parametricamente um modelo-base de poço de luz de seis pavimentos na cidade de São Paulo, Brasil, variando, em casos alternativos, sua dimensão geométrica, a refletância das suas paredes e a abertura da janela das salas conectadas a ele. Para a avaliação da iluminação natural, foram utilizadas, através do software ClimateStudio, as métricas Annual Sunlight Exposure (ASE1000) e Spatial Daylight Autonomy (sDA300/50%). Observou-se que o aumento da refletância é uma solução que melhora a distribuição da iluminação natural sem elevar os níveis de luz solar direta, enquanto o aumento da dimensão geométrica resulta em maior alcance da luz solar direta no poço, não ultrapassando o quarto pavimento. Para minimizar o risco de desconforto visual nos ambientes, as janelas devem ter abertura menor na metade superior e maior na metade inferior do poço de luz. Assim, as variáveis consideradas contribuem, de maneira distinta, para o aumento da iluminação natural nos ambientes avaliados, porém é necessário considerar o risco de desconforto visual em alguns casos.

Abstract: The present work aims the association of factors linked to the habitability satisfaction of isolated and semi-detached residential units in apartment buildings is analyzed, during lockdown due to Covid-19 in Argentina. Using the snowball technique, an electronic survey is disseminated in the strictest lockdown moment, that reaches a sample of 137 users of residential units. The answers for two research questions are empirically validated with inferential statistical techniques, giving rise to hypotheses born from the conflicting aspects detected in habitability satisfactions such as the availability of interior spaces, perceived natural lighting, the age of the respondent, among others. Conclusions confirm the relevance of natural lighting could replace the demand for spatial amplitude, and its importance based on the users age range among other aspects of significant association. Results obtained constitute foundations for policy, both housing and territorial planning in order to mitigate the dissatisfaction with habitability risk in a social confinement event.

Resumen: En el presente trabajo se analiza la asociación de factores vinculados a la satisfacción de habitabilidad de unidades residenciales de tipo aislada y adosada en edificios de departamentos, durante el confinamiento social por Covid-19 en Argentina. Mediante la técnica de bola de nieve se difunde una encuesta electrónica en el momento más estricto del confinamiento social, que alcanza una muestra de 137 usuarios de unidades residenciales. Las respuestas a las dos preguntas de investigación planteadas se validan empíricamente con técnicas de estadística inferencial, dando lugar a hipótesis nacidas en los aspectos conflictivos detectados en las satisfacciones de habitabilidad tales como la disponibilidad de espacios interiores, la iluminación natural percibida, la edad del encuestado, entre otros. Las conclusiones confirman la relevancia de la iluminación natural en sustitución de la demanda de amplitud espacial, y su importancia a partir del rango etario entre otros aspectos de asociación significativa. Los resultados obtenidos constituyen fundamentos para propuestas de políticas tanto de vivienda como de ordenamiento territorial en vistas a una mitigación del riesgo de insatisfacción de habitabilidad ante sucesos de confinamiento social.

ABSTRACT: When applied at growing phase, lighting program aims to obtain quails with body weight and physiological maturity suitable for the beginning of laying. This study evaluated lighting programs at growing phase on performance, sexual maturity and egg quality of meat quail breeders (Coturnixcoturnix) at laying phase. From 7 to 49 days of age, 300 female meat quails were subjected to three lighting programs (natural, intermittent and continuous), with 5 replicates of 20 birds each. At 49 days of age, 240 quails were transferred to a shed, maintaining the same experimental conditions. Meat quails submitted to continuous and intermittent lighting programs had higher weight of reproductive system and lower ages for first egg production and to reach 50% of egg production (P < 0.05). Quails submitted to natural lighting had lower feed intake from 49 to 70 and 71 to 92 days of age and worse feed conversion up to 114 days of age. Continuous and intermittent lighting programs resulted in more precocious quails compared to natural lighting program. Quails submitted to natural lighting at growing phase presented lower egg production during all periods, not differing for birds submitted to continuous and intermittent programs from the second period (71 to 92 days of age). Intermittent and continuous lighting result in better feed conversion of breeding quails up to 114 days and a higher percentage of laying (49 to 136 days), reducing the number of days to produce the first egg and to reach 50% of laying, in relation to natural lighting.

RESUMO: Quando aplicado na fase de crescimento, o programa de luz visa obter codornas com peso corporal e maturidade fisiológica adequados para o início da postura. Este estudo avaliou programas de iluminação na fase de crescimento sobre o desempenho, maturidade sexual e qualidade dos ovos de codornas de corte reprodutoras (Coturnix coturnix) na fase de postura. Durante o período de sete a 49 dias de idade, 300 codornas de corte fêmeas foram submetidas a três programas de iluminação (natural, intermitente e contínuo), com cinco repetições de 20 aves cada. Aos 49 dias de idade, 240 codornas foram transferidas para um galpão, mantendo a mesma distribuição experimental e submetidas às mesmas condições. As aves submetidas aos programas de iluminação contínuo e intermitente na fase de crescimento apresentaram maiores peso relativo do sistema reprodutivo e consequentemente menores idades para produção do primeiro ovo e para atingir 50% da produção de ovos (P < 0.05). As aves que receberam apenas iluminação natural apresentaram menor consumo de ração nos períodos de 49 a 70 e 71 a 92 dias de idade e pior conversão alimentar até 114 dias de idade. Os programas de iluminação contínua e intermitente na fase de crescimento resultaram em codornas mais precoces quando comparados as aves submetidas ao programa de iluminação natural. Codornas submetidas a programa de luz natural na fase de crescimento apresentaram menor produção de ovos durante todos os períodos, não diferindo das aves submetidas a programas contínuos e intermitentes a partir do segundo período (71 a 92 dias de idade). A iluminação intermitente e contínua na fase de crescimento resulta em melhor conversão alimentar de codornas reprodutoras até 114 dias e maior percentual de postura (49 a 136 dias), reduzindo o número de dias para produzir o primeiro ovo e atingir 50% de postura, em relação a iluminação natural..

The aim of this work was to construct and characterize dye-sensitized solar cells (DSSC) using alternative materials and low-cost equipment. Instead of using the TiO2 semiconductor, a water-based white paint pigment was employed as a substitute. This pigment, when combined with natural dyes, absorbs visible light and acts as the photoelectrode. Pencil graphite was utilized to create the conductive layer, serving as the positive electrode. Lugol’s solution was employed as the electrolyte to establish electrical contact between the two electrodes. These materials were assembled between two glasses with a conductive surface made of tin oxide doped with fluorine (FTO glass). Subsequently, the assembled devices were exposed to three types of lamps: daylight (45 W), LED (15 W), and halogen (105 W), all positioned at the same height as the solar cell. Voltage and current measurements were taken using a simple multimeter. These results enabled the correlation of theoretical concepts related to absorption (dye) and light emission (lamp) ranges, different types of anchoring groups, and the dye-semiconductor anchoring mode. The voltage and current production were found to depend on the type of lighting source. However, it became evident that several factors beyond those mentioned strongly influenced the energy production mode of the solar cell. dyesensitized dye sensitized DSSC (DSSC lowcost low cost equipment TiO semiconductor waterbased water based substitute dyes photoelectrode layer electrode Lugols Lugol s electrodes FTO glass. glass . glass) Subsequently lamps 45 (4 W, W , W) 15 (1 105 (10 cell multimeter (dye lamp (lamp ranges groups dyesemiconductor source However 4 ( 1 10

This work presents a new filming technique for objects captured in motion that minimizes the typical trail (blur) left in the recorded videos, increasing the accuracy of the video analyses. In order to reduce this trailing, we present a new technique called video analysis by stroboscopic illumination. The technique consists of filming the object of study illuminated only by short and intense pulses of light, without natural or artificial ambient lighting. An electronic device generates the pulses at a frequency adjustable to the frequency of the frames per second that take part in the video. As a result, we present an example of the proposed technique by filming a rubberized sphere launched from a ramp. This technique makes it possible to film by cell phones with low-resolution cameras and a low acquisition rate, allowing the improvement of the results of motion measurements. blur (blur videos analyses trailing illumination light lighting result ramp lowresolution resolution rate measurements

Abstract The potential of daylight harvesting is related to the building location. However, climatic zonings adopted by energy efficiency programs focus only on the thermal performance, neglecting important variables of the buildings’ luminous performance. This paper aims to investigate the relationship between the angle of solar incidence, the annual occurrence of clear sky, and the annual lighting energy consumption when daylight harvesting is practiced. The lighting consumption of a square floor space, orientated in the cardinal directions, was simulated for 20 Brazilian cities. The frequency of the 15 CIE sky types was determined for each city using weather files and the angle of solar incidence was calculated for each hour of the year. The analysis comprised graphical exploration, Pearson's correlation, and multiple regression. The sensitivity of the consumption to the other two variables could be perceived in the hourly but not the annual analysis. The correlation between annual consumption and latitude was more robust for the intertropical range, with increased consumption moving south, and varied significantly for each orientation. It was concluded that, although relevant, the variables are not representative of variations in annual lighting consumption for application in climate zoning.

O aproveitamento da luz natural está relacionado à localização do edifício. Tadavia, os zoneamentos climáticos dos programas de eficiência energética focam no desempenho térmico, negligenciando importantes variáveis do desempenho luminoso das edificações. Este trabalho objetivou investigar a relação entre o ângulo de incidência solar, a ocorrência anual de céu claro e o consumo anual de iluminação, considerando o aproveitamento da luz natural. Simulou-se o consumo de iluminação de um ambiente quadrado, orientado aos pontos cardeais, para 20 cidades brasileiras. Determinou-se a frequência dos 15 tipos de céu CIE para cada cidade, usando-se arquivos climáticos, e calculou-se o ângulo de incidência solar para cada hora do ano. A análise compreendeu exploração gráfica, correlação de Pearson e regressão múltipla. A sensibilidade do consumo às outras duas variáveis pode ser percebida na análise horária, mas não na anual. A correlação entre consumo anual e latitude foi mais robusta para a faixa intertropical, com o consumo aumentando para o sul, e variando significativamente para cada orientação. Concluiu-se que, embora relevantes, as variáveis não são representativas das variações de consumo anual de iluminação para aplicação em zoneamentos climáticos.

Abstract: Architectural space is relevant in the teaching-learning process; in this sense, Reggio Emilia pedagogy considers space as the third teacher. In this work, the architectural premises of the pedagogical model were identified, evaluation instruments were developed and applied to case studies. Six schools in different countries were evaluated. The school located in Japan obtained the highest score (16/17), while a case study located in Mexico obtained the lowest score (10/17). Overall results showed that contact with the outdoors was the premise with the highest score (100%), in second place connection with nature (72%) and in third place the incorporation of a space (63%). Information on projects that incorporate the architectural premises of Reggio Emilia pedagogy, as well as their evaluation, is scarce, so it is necessary to disseminate and analyze these educational spaces and develop evaluation instruments.

Resumen: El espacio arquitectónico es relevante en el proceso de enseñanza-aprendizaje; en este sentido, la pedagogía Reggio Emilia considera el espacio como el tercer maestro. En este trabajo se identificaron las premisas arquitectónicas del modelo pedagógico, se desarrollaron instrumentos de evaluación y se aplicaron a casos de estudio. Seis escuelas en diferentes países fueron evaluadas. La escuela localizada en Japón obtuvo el mayor puntaje (16/17), mientras que un caso de estudio localizado en México obtuvo la menor puntuación (10/17). Resultados globales mostraron que el contacto con el exterior fue la premisa con mayor puntaje (100%); en segundo lugar, conexión con la naturaleza (72%), y en tercer lugar la incorporación de un espacio plaza (63%). La información sobre proyectos que incorporen las premisas arquitectónicas de la pedagogía Reggio Emilia, así como su evaluación, es escasa, por lo que es necesario difundir y analizar estos espacios educativos y desarrollar instrumentos de evaluación.

RESUMO O acesso à moradia nas camadas sociais de baixa renda levanta a necessidade de uma reflexão relevante para a América Latina. Nesse contexto, foi desenvolvida uma Solução Habitacional Modular (SHM) de madeira em um bairro da periferia da CABA (Cidade Autônoma de Buenos Aires) chamado Partido de La Plata, com foco na melhoria habitacional das camadas populares e gerenciada por uma cooperativa de trabalho, a universidade e o setor científico-tecnológico. O objetivo é avaliar o desempenho térmico, lumínico e as condições de estanqueidade do envelope construtivo de uma SHM de madeira na região do Partido de La Plata em um clima temperado-quente. Para isso, em primeiro lugar, foi realizado um monitoramento interno e externo (temperatura, umidade relativa e iluminação natural), em seguida, foram avaliados os aquecedores solares de ar e, por fim, foi realizada termografia digital noturna. Os resultados mostram desempenhos favoráveis na iluminação diurna e uma boa resposta térmica diurna durante períodos frios. No entanto, também foram encontrados aspectos a serem melhorados, como a necessidade de condicionamento térmico noturno, melhoria na estanqueidade do envelope, ventilação noturna em períodos quentes, reforço do sombreamento e isolamento térmico.

ABSTRACT Access to housing in low-income sectors brings up the need for a relevant reflection on Latin America. In this context, a wood-based Modular Housing Solution (MHS) has been developed in a neighborhood on the outskirts of CABA called La Plata, oriented to a housing improvement for working-class sectors, and managed by a labor cooperative, the university, and the scientific-technical sector. The objective is to evaluate the thermal and light behavior and the airtightness conditions of the building envelope of a wooden MHS in the La Plata district in a warm-temperate climate. For this purpose, first, indoor and outdoor monitoring (temperature, relative humidity, and natural lighting) was carried out, then the solar air heaters were evaluated, and finally, digital thermography was performed at night. The results show favorable daytime lighting performance and good daytime thermal response in cold weather. However, there was also room for improvement, such as the need for thermal conditioning at night, improvement of the airtightness of the envelope, night ventilation in warm seasons, reinforcement of shading, and thermal insulation.

RESUMEN El acceso a la vivienda en los sectores sociales de bajos ingresos plantea la necesidad de una reflexión relevante para América Latina.

Se tiene por objetivo evaluar el comportamiento térmico, lumínico y las condiciones de estanqueidad en la envolvente edilicia de una SHM de madera del sector Partido de la Plata en un clima templado-cálido. Para ello, en primer lugar, se realizó un monitoreo interior y exterior (temperatura, humedad relativa e iluminación natural), luego se evaluaron los calefactores solares de aire y finalmente se realizó termografía digital nocturna. Los resultados muestran desempeños favorables en el aspecto lumínico diurno y una buena respuesta térmica diurna en épocas frías. No obstante, también se encontraron fenómenos por mejorar, como la necesidad de acondicionamiento térmico nocturno, de mejora de la estanqueidad de la envolvente, de ventilación nocturna en épocas cálidas de refuerzo del sombreo y del aislamiento térmico.

ABSTRACT The present study was executed to evaluate the effect of lighting programs for meat quails on their bone growth and development. A total of 1500 sexed European quails (Coturnix coturnix coturnix) were distributed using a completely randomized design in a 2 × 3 factorial arrangement, with two sexes and three lighting programs (natural, intermittent, and continuous) with five replicates of 50 quails. The lighting programs were applied in the period from 7 to 49 d of age. Weekly slaughterings were performed to remove the tibiotarsus and femur and subsequently determine weight, length, dry and mineral matter content. The growth and deposition curves of dry and mineral matter in the bones were obtained using the Gompertz model. There was no significant interaction between lighting programs and sex for the estimates of the Gompertz curve parameters of all variables studied. There was an effect of the lighting programs only on the time needed to reach the maximum deposition rate of the growth curve and dry and mineral matter deposition. Females showed higher weight and deposition of mineral matter at maturity, and took longer to reach the maximum deposition rate value for these variables. There was influence of the lighting programs on resistance and bone deformity of the tibiotarsus. For quails raised in the tropical region, a natural or intermittent lighting program must be used, as it does not compromise the development of bones and assures bone quality. 150 Coturnix arrangement natural, (natural continuous 5 4 age length content model studied maturity region used quality 15 1

ABSTRACT This research aimed to study the effect of light regime on performance and egg quality of white laying hens applied at the start laying phase. A total of 420 Hy line White laying hens, at 19 weeks of age were used, distributed in a completely randomized design, during 5 periods of 28 days, extending from January to June, corresponding to the age of 19 to 38 weeks of age of the birds. Three lighting programs were evaluated: continuous 16 h of light and 8 h of dark (CONT); intermittent program with two 2-min photophases equidistant at 16 h between natural light and 8 h of dark (INT) and continuous program only using decreasing natural light (LND). Feed intake (g/bird/day), egg production (%bird/day), egg weight (g), egg mass (g/bird/day), feed conversion (g/g) and egg density (g/cm3) were evaluated. Feed intake and feed conversion were higher (p<0.05) in birds submitted to the CONT program compared to the LND program, however the CONT and LND programs did not differ (p>0.05) from the INT. Egg production, egg weight, egg mass and egg density were similar (p>0.05) between programs. Intermittent program with two photophases of 2 min equidistant 16 h between natural light can be applied in light layers at the start laying phase without impairing the productive performance and eggshell quality.
