Children inhale indoor air at 400 mL/min∙kg per body weight, 2.76 times more than adults. They have weaker immunity than adults and are more exposed to asthma, allergies, and atopic diseases. The objective of this paper is to suggest effective management and improvement measures for indoor air quality for nurseries. As a methodology, 16 nurseries (total of 35 classrooms) were selected to measure the indoor air quality compared with WHO IAQ Standard, and identify the daily concentration change of the pollutants. Based on the measurements, IAQ improvements for selected facilities are carried out to compare the results before and after improvement. The result has shown that the concentration of Carbon Dioxide (CO2), Total Volatile Organic Compounds (TVOC), Total Suspended Particles (TSP) and formaldehyde (CH2O) exceeds WHO IAQ standards. The concentration of CO2 and TSP is changed mainly by physical activity of children and that of CH2O and TVOC is changed mainly by ventilation after school start. TVOC decreased by 46.4% and the TSP decreased by 21.7% after air purifier, but CH2O and TVOC increased 1.8–3.8 times after interior renovation with low-emission finishing materials. After new ventilation installation, the CH2O and TVOC reduced half and the TSP reduced one third. It is proven that the most effective way to reduce the concentration of air pollutants in nurseries is the installation of a new ventilation system, followed by an air purifier. The renovation with low-emission finishing materials cannot improve IAQ in a short period of time.
The elderly are the most predicted users for smart home technology in the United Arab Emirates and the population over 65 is expected to increase to 24.3% by 2030. Despite the rapid development of smart home technology, research has been mainly focused on technology development. To encourage conservative elderly users, however, smart home technology should be implemented for UAE elderly users to accept and integrate it into their daily lives. The objective of this paper is to analyze the preferences and needs of smart home technologies to understand the behaviors of UAE elderly users, and the factors affecting the acceptance of technology. As a methodology, a survey and interview were conducted for 110 people in their 40s and 60s and a total of 105 valid survey responses were collected and used as data for frequency, mean, cross-analysis, independent sample t-test, one-way variance analysis, and multiple regression analysis with IBM SPSS statistics 27. The results showed that 67.0% of UAE elderly users have chronic diseases such as high blood pressure (16.2%), heart disease (3.8%), diabetes (32.4%), or arthritis (10.5%). Therefore, smart home technology for health management is inevitable to improve overall lifestyles. It was statistically proven that UAE elderly users want automatic fall detection in the living room (39.0%) and bedroom (25.7%). Lifestyle monitoring in living room (44.7%) and bedroom (18.1%); the elderly preferred living room most for daily life assistance (36.2%), environmental control (50.5%), health and biometric monitoring (49.5%), and video conferencing (82.9%). In the case of sensors, elderly preferred the switch at the entrance (36.2%), and motion detecting sensors (42.9%), video cameras (56.2%), and voice recognition (50.5%) sensors in the living room. However, UAE elderly users do not think smart home technology can protect their privacy. It is found that age group and computer technology affinity are the most influential variables and UAE elderly users have an anxiety about technology, which influenced the acceptance of smart home technology.
This study investigates the tourism-oriented heritage districts in the United Arab Emirates (UAE) and explores a new approach to fostering heritage tourism. This is envisaged through conducting a post-occupancy evaluation (POE) to detect the characteristics of the tourism-oriented heritage districts from the residents and tourists. The systematic evaluation of opinions is based on indicators developed by UNESCO and ICOMOS international principles. According to the survey results, it is found that Dubai’s approach was successful at reuniting people with their history via modern materials in the restoration works. This has preserved the heritage value and increased their culture and national identity. The social goal to reconnect residents to their cultural history has been realized despite the inconsistencies compared to the specification of the World Heritage Convention, which requires technical authenticity and integrity. People perceived the identities of tourism-oriented heritage districts in Dubai, Sharjah, and Ajman differently. Based on the POE survey, the Shindagha area and Al Fahidi Historical Area in Dubai were perceived as traditional destinations for tourist attractions. The Heart of Sharjah area was perceived as cultural and educational tourism, and the Ajman Heritage District area was perceived as community tourism.
Due to fast economic development, Dubai has built many high-rise apartments in a short period of time. The Dubai Municipality attempts to control indoor air quality with strict regulations, but the detailed provisions are still not comprehensive. The objective of this paper is to conduct on-site measurements for new high-rise apartments before moving on to investigate indoor air pollution and to analyze pollutant emissions by type of finishing material. As a methodology, on-site measurements were conducted fornine different housing units (three lower, three middle, and three higher floors) before moving on to investigate the status of indoor air pollution in new apartments. Based on the on-site measurements data, lab experiments with a small chamber for the same finishing materials from the most polluted housing unit (a lower two bedroom unit) were conducted to measure the emission of pollutants over 30 days. The result shows that the average of CH2O (64.4 μg/m3 for studio, 64.5 μg/m3 for one bedroom, and 83.4 μg/m3 for two bedroom) was lower than the standard (100 μg/m3) in all units, while the average TVOC (520.1 μg/m3 in the studio, 509.5 μg/m3 in one bedroom, and 754.7 μg/m3 in two bedroom) exceeded the standard (500 μg/m3) in most of the units. It was proven that regarding the CH2O, silk wallpaper, initial wallpaper, and wallpaper adhesive had the highest emissions and for the TVOC, tile and tile adhesive had the highest emission. During small chamber experiments, CH2O and TVOC emissions tended to decrease gradually over time, but the emission amount changed significantly in high pollutant emission material especially from day 1–10. Therefore, Dubai municipality should establish the regulation for residents to move into their new apartment after at least 10 days to avoid the high polluted emission from the curing process of the interior finishing material.
The population of Dubai has increased dramatically in the last 40 years. Along with social changes, neighborhood parks are becoming increasingly important for enhancing the residents’ quality of life. This study aims to evaluate the physical environment of parks and investigate park users’ satisfaction in neighborhood parks of Dubai. After defining the park and surrounding environment for access, a field survey was performed at Bay Avenue Park and Al Ittihad Park. The data for analysis were collected from the Department of Geographical Information System (GIS) Center at Dubai Municipality. The results show that the standard duration was 60–90 min, and the walking/driving time was 10–20 min. “Children Facility” and “Various Attractions” were low in both parks. The statistical results of multiple regression analysis of the derived factors and satisfaction show that Bay Avenue Park influenced satisfaction in the surrounding environment for access, pedestrian space, park facility, convenience and comfort of the park, and various attractions and activities. Furthermore, Al Ittihad Park influenced satisfaction in pedestrian space, green landscape, surrounding environment for access, park facilities, and safe access. Therefore, factors such as park facilities, surrounding environment for access, and pedestrian space were analyzed to affect satisfaction in both parks. The analysis of the surrounding environment for access factors using GIS would methodologically help determine priorities for future improvements around parks. However, this study is limited by the scope and investigation period of the target parks, and detailed factors related to the surrounding environment for access are also not evaluated.
