UNLABELLED Environmental conditions such as lighting and thermal comfort are influencing factors on sleep quality and visual tiredness. The purpose of this study was the determination of the relationship between thermal comfort and light intensity with the sleep quality and eye fatigue in shift nurses. METHOD This cross-sectional research was conducted on 82 shift-work personnel of 18 nursing...

Background Thermal component of the atmospheric environment is an important issue which is related to human's health. Thermal environment includes both heat exchange conditions (stress) and the physiological response (strain). The aim of this study was to measure the association of heat indices (PSI, HSI, Humidex) especially subjective one (STI) with some physiological parameters (Blood pressur...

this paper presents a case study to determine the efficiency of the currently used heat stress indices in correlation with wet bulb globe temperature (wbgt) as a permissible index at a foundry plant and to evaluate the extent of the physiological responses such as heart rate and body temperature in correlation with heat stress indices. the field consisted of a foundry plant where a shift work w...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

Introduction: Workers in the Indonesian steel manufacturing industry are subject to many heat stress risk factors, ranging from equatorial climate physically demanding work tasks which may result heat- related illnesses and reduced worker productivity. Hence, a study was conducted at Steel Mill X assess level of among its workers, determine association factors provide meaningful recommendations...

Introduction: Global warming is likely to affect certain groups such as workers in heat-producing industries. With limited research exploring an important area, this study aimed explore the heat stress vulnerability and adaptive strategies of indoor small-scale factory workers. Methods: This was a cross-sectional mixed-method approach used. The setting units. quantitative component included env...

One of the most critical variables in field thermal comfort measurements is mean radiant temperature which typically measured with a standard 150 mm black globe thermometer. This also reference instrument required for assessment heat stress conditions by means well-known Wet Bulb Globe Temperature index (WBGT). However, one limitations this method represented relatively long response time. why ...

Objective. To analyze the climate in last thirty years Northwest of Minas and its impacts on dairy production. Materials Methods. The database National Institute Meteorology was used during period from 1985 to 2017 cities Unaí, Paracatu, Arinos Formoso/MG. For each month year, average minimum temperature (Tmin), maximum (Tmax), relative humidity (RH), Temperature Humidity Index (THI), Wet-bulbe...
