Abstract The comfort temperature and sleep quality of Indonesian residing in Japan during summer might be different from Japanese. As an extended previous research, this study aimed to compare the thermal comfort and sleep quality between Japanese and Indonesian students. Male Indonesian and Japanese students aged 20-35 years participated in this study. The participants completed a survey regarding thermal sensation before sleep. During sleep, actigraphy was used to monitor sleep. Additionally, the temperature and relative humidity of the participants’ bedrooms were recorded. The findings of this study indicated that Indonesian students’ bedroom temperature and relative humidity were not significantly different from those of Japanese students during the summer. Most of Indonesian students preferred neutral, like the Japanese students. According to a thermal comfort survey, Indonesians had the same sensation as Japanese (slightly comfortable). However, the Griffiths method revealed that the mean comfort temperature of Indonesian was higher than those of Japanese students. We also discovered that Indonesian students had shorter duration on bed and sleep minute than Japanese students. Furthermore, the sleep rate of Indonesian students was comparable to that of Japanese students. In conclusion, Indonesian students as tropical native became capable of adjusting to the hot and humid conditions in temperate climate, Japan.

Thermal comfort is crucial in satisfaction and maintaining quality sleep for occupants. In this study, we investigated the comfort temperature in the bedroom at night and sleep quality for Indonesian students during summer and winter. Eighteen male Indonesian students aged 29 ± 4 years participated in this study. The participants had stayed in Japan for about six months. We evaluated the sleep parameters using actigraphy performed during summer and winter. All participants completed the survey regarding thermal sensation, physical conditions, and subjective sleepiness before sleep. The temperature and relative humidity of participants’ bedrooms were also measured. We found that the duration on the bed during winter was significantly longer than that during summer. However, sleeping efficiency during winter was significantly worse than that during summer. The bedroom temperature of the participants was in the range of comfort temperature in Indonesia. With the average bedroom air temperature of 22.2 °C, most of the participants still preferred “warm” and felt “slightly comfortable” during winter. The average comfort temperature each season calculated using the Griffiths method was 28.1 °C during summer and 23.5 °C during winter. In conclusion, differences in adaptive action affect bedroom thermal conditions. Furthermore, habits encourage the sleep performance of Indonesian students.

Studies of the urban climate involve numerous climatic variables, such as temperature, air humidity and vegetation. The objective of this research was to determine the trend of two meteorological variables (air temperature relative humidity), in relation to the arborization, sensation and thermal hygrometric perception of the population in the microclimate of two areas (A1 = Avenue Antônio Maia; A2 = Street 5 de Abril) Core Marabá Pioneira. For the measurement of temperature and humidity of the air, the methodology recommended by the Agronomic Institute of Campinas (IAC), adapted for the schedules and collection numbers, was applied. To obtain data on thermal comfort, seventy mixed forms were applied for two consecutive days at 12 hours. The thermal sensation was classified per the contained in the Predicted Mean Vote (PMV) and the discomfort, with the Thom Discomfort Index (ID). Twelve daily readings (6:00 a.m. to 5:00 p.m.) were carried out at each hour in the four meteorological shelters (two in each area) during 23 days of July 2015. The results indicated that the air temperature has tendencies to elevation, The relative humidity of the air, presents opposite tendency. The thermal sensation is very hot (+3), the satisfaction with shading was classified as good (A2 = 50%) and regular (A1 = 41.67%), thermal comfort (A1 = 28.76 °C; A2 = 27.70 ºC), ranges from uncomfortable to very uncomfortable. Therefore, there is a need to improve afforestation in the Marabá Pioneira Nucleus, in order to reduce the discomfort index and the quality of life of the population.

Abstract Purpose: This study aimed to assess the burden of care and its relationship with sleep quality of cancer patients’ caregivers.Methods: This descriptive-correlational study was conducted in a referral center of cancer in Zanjan, northwest of Iran. 135 caregivers of cancer patients were recruited through convenience sampling method. The data were collected using a demographic characteristics questionnaire, Novak and Guest’s caregiver burden inventory and Pittsburgh sleep quality index (PSQI). The collected data was analyzed using descriptive and inferential statistics.Results: The mean (± SD) age of the participants was 39.71 (± 10.74) years. The mean (± SD) burden of care and sleep quality of the participants was 45.22 (± 17.75) and 8.88 (± 4.21), respectively. It was found that there is a significant positive relationship between burden of care and quality of sleep scores (r = 0.65, P < 0.001).Conclusion: cancer patients’ caregivers endure a remarkable burden of care and their sleep quality is undesirable. Results indicated that an increase in the burden of care reduces the caregiver’s quality of sleep. High burden of care and poor sleep quality may reduce the quality of the provided care that increase the costs and weakens the disease prognosis. According to the study results, reducing burden of care is an effective strategy regarding improving the caregivers’ quality of sleep that can improve the quality of provided cares by caregivers.

Negative Impacts

In recent years, Mizoram has made immense progress in various sectors and initiated developmental programmes for its economic growth. An important contributing factor to this development and growth is the transport connectivity projects. Although connectivity projects can boost economic growth, its negative effects cannot be neglected. In view of this, the present research studies the impacts of Champhai – Zokhawthar road construction on the air quality and noise quality of the region. This comparative study of the impact on the quality of air and noise pollution in the pre-construction phase and construction phase provide a clear-cut example of the negative impacts caused by road construction and provide a fresh outlook for formulation of improved management plans. Air quality assessment was carried out using High Volume Air Sampler and the following parameters were monitored – suspended particulate matter (SPM), respirable suspended particulate matter (RSPM), nitrogen dioxide (NO2) and sulphur dioxide (SO2). The results indicate that mean SPM concentration was increased by 22.82 µg/m3; RSPM concentration by 14.67 µg/m3; NO2 concentration by 4.08 µg/m3; and SO2 concentration was increased by 0.06 µg/m3 from the pre-construction phase to construction phase. Noise quality assessment was carried out at three sites – Zotlang, Melbuk and Zokhawthar by using Lutron SL-4001 Sound Level Meter and Leq, Lmax and Lmin were recorded and calculated. The mean noise level at Zotlang wasincreased by 8.72 dB (A) and at Melbuk the mean noise level was increased by 9.35 dB (A). However, at Zokhawthar, there was a decrease in mean noise level by 0.13 dB (A). From the present study, it is evident that road construction poses a threat to the air quality and noise quality of the study area and improved measuresneed to betaken to curb its negative impacts

Abstract Background: COVID-19 pandemic has negatively affected the entire world and one of its impacts was the increased level of stress and anxiety, especially among healthcare workers. Therefore, this study aims at evaluating the quality of life (QoL) and sleep quality of healthcare professionals in Iraq.Methods: This study assessed the QoL and sleep quality by using World Health Organization Quality of Life Instruments (WHOQOL-BREF) and the Insomnia Severity Index (ISI) respectively. The questionnaires were administered through an online cross-sectional survey targeted at workers in medical fields in Iraq from 1st to 20th of August 2021. Results: Three hundred medical health workers participated, and females constituted 75.3%. The two questionnaires had very good internal consistency. The highest scoring domain was the social relationships, followed by physical health. Significant difference was found in the mean scores of psychological health domain between males and females, with higher scores observed in males. The mean of the total ISI score was 11.58 ± 6.88 with a range between 0 and 27. Severe insomnia was observed in only 9.7% of the participants. A significant negative correlation (r = -0.118) was found between age and ISI scores of the participants. Significant differences were found between males and females with higher ISI mean score observed among males. Conclusion: The quality of life and sleep pattern can be impacted by COVID-19 infection with the psychological aspect of QoL being the most affected and some degrees of insomnia being observed in many participants.
