Developing a Policy Model to Support Family Caregivers of Dependent Older Adults in Bangkok

This article aims to present the situation of family caregivers of dependent older individuals in the Bangkok area and proposes a model policy to support them. This study used mixed methods with a multi-phase design. Based on 357 participants, the results indicate that family caregivers in Bangkok faced problems, with moderate levels (x ̅ = 2.51) in caring for older dependents and their roles as direct caregivers. Yet, they hold high expectations for support (x ̅ = 3.86). The proposed model comprises four components derived from exploratory factor analysis of quantitative data, supplemented by qualitative data from a case study involving five individuals, tested and assessed by Bangkok executives or representatives (totaling six individuals), along with seven practitioners supporting older adult caregivers. These components include establishing systems, mechanisms, rights, and welfare; supporting work and relaxation; creating all-inclusive care service units for dependent older individuals; and providing medical and public health services. Implementing local-level policies is crucial for supporting family caregivers, with the Department of Older Persons collaborating with civil society for integration and engagement. Through this collaboration, concrete forms of support for family caregivers of independent older individuals are expected to be established.

Indoor air pollutants and microbes in mass rapid transit (MRT) trains of north-western area of Bangkok, Thailand: Impact on indoor air quality and human health

Most modern cities suffer from urban air pollution caused by human activity such as traffic and other sources. Various pollutants in the environment may pose a threat to the health of commuters. The objective of this study is to assess the indoor air quality (IAQ) in MRT purple line trains serving the north-western area of Bangkok in order to determine any potential impacts on human health. The monitored parameters include total volatile organic compounds (TVOCs), temperature, relative humidity, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), formaldehyde (CH2O), and fine particulate matter (PM2.5). The indoor air pollutant concentrations in the MRT remained within the permissible thresholds. The results of the correlation analysis reveal that relative humidity (RH) and PM2.5 are positively correlated in both the wintertime and summertime measurement campaigns. In contrast, CO2 correlated with temperature in the wintertime and CO in the rainy season. Bacterial and fungal loads were estimated during various measurement campaigns in MRT. Fungi and bacterial loads were higher in the MRT trains during the wintertime and rainy season campaigns. The IAQ of MRT train in Bangkok is within the satisfactory and excellent category of air quality index (AQI). The inhaled doses of PM2.5, CO, and VOCs were also estimated to identify their health effects on commuters. The inhaled dose of PM2.5 was comparatively higher than other pollutants. In this study, a general perspective of the IAQ in the MRT system was provided. It is recommended to conduct more research studies on various MRT lines in Bangkok to further investigate the levels of bacteria, fungi, TVOCs, O3, and PM. Additionally, the ventilation mode in MRT needs to be investigated as it is the main factor affecting the IAQ.

The Effectiveness of a Self-Management and Multifactorial Program for Blood Pressure Control Among Older Home-Based Workers in Urban Bangkok, Thailand

Older adults aged between 50-65 years old have a high risk of hypertension. With the growing numbers of home-based workers among adults and older adults in Thailand, this study aimed to evaluate the effectiveness of self-management with a multifactorial program to control blood pressure among older adults. A randomized controlled trial was conducted. Participants who worked as home-based workers aged between 50-65 years old were recruited from a community in the western area of Bangkok. Approximately 70 participants were randomly and equally assigned to the intervention and control groups (35 participants in each group). Participants in the intervention group received the program that consisted of education regarding food selection, work time management and arm swinging; a practical protocol, an exercise program, a heart rate monitor, a recorded book for facilitating participants’ progress to ensure their safety and efficiency in a health professional manner for a week/month. While those in the control group received usual care. A Knowledge Attitude Practice questionnaire was utilized to assess their knowledge, attitude, and practice, which demonstrated a content validity index and Cronbach alpha of 0.80, respectively. The Citizen CH-403C was utilized to measure blood pressure and heart rate. Two-way Repeated Measures ANOVA was employed to analyze the differences in outcome scores at baseline, 3-month after program, and 6-month follow up. The results showed a significant increase in participant’s knowledge, attitudes, and behaviors toward hypertension and a decrease in blood pressure to nearly normal after 3months following the completion of the program and 6-month follow-up. Therefore, the self-management and multifactorial program could be an effective preventive intervention for older adults with pre-hypertension conditions to offer them valuable knowledge on work-life balance as well as to help prevent hypertension, and related stroke complications.

Evolution Pattern of Land Subsidence Using InSAR Time-Series Analysis in Bangkapi, Bangkok, Thailand

Subsidence in Bangkok has occurred continuously for a long time. This research applied radar satellite imagery (Sentinel-1 101 images, 2017–2022) to track land subsidence using the time series INSAR technique. The study area was in the Bang Kapi area in Bangkok, which has a high level of cumulative subsidence. The pattern of cumulative subsidence change was analyzed using the standard deviation ellipse (SDE) technique. The results showed that the Bang Kapi area had the highest cumulative subsidence in 2019 (-125.31 mm). The movement of the subsidence center changed every year in different directions with three patterns identifiable. The first pattern showed the evolution of subsidence in a northeast-southwest direction, the second pattern showed subsidence evolution in a northwest-southeast direction, and the third pattern presented evolution that did not appear to be in any specific direction. The size of the subsidence area in 2017 and 2022 increased, whereas between 2018 and 2021, the subsidence area decreased compared to other years during the research period.

A relationship between urban green space and PM2.5 levels in urban and suburban areas of Bangkok

Abstract Bangkok, Thailand's densely populated capital, faces critical air pollution due to overpopulation, traffic, industry, and biomass burning. Of particular concern is the escalating PM2.5 pollution, which poses significant risks to both public health and the environment. This research investigates the relationship between Bangkok's urban green spaces (UGS) and PM2.5 levels by comparing the concentrations of PM2.5 in non-green areas (on roads) and green areas (city parks) in both urban (Ratchathewi) and suburban (Lat Krabang) locations. The methodology in this study involves data collection from secondary sources and statistical analysis using ANOVA, T-tests, and the Mann-Kendall test with Sen's slope. The findings indicate a consistent expansion of UGS within the study areas, while levels of air pollution exhibit discernible seasonal fluctuations. Notably, concentrations of PM2.5 near roads were significantly higher than those of nearby parks, with 43% and 38% higher levels at Ratchathewi and Lat Krabang, respectively. Several factors contribute to this discrepancy, encompassing the proximity to pollution sources, the processes of dispersion and dilution, the presence of vegetation and green spaces, and the role of physical barriers. Based on the research findings, recommendations propose to improve air quality through UGS initiatives and collaboration with relevant stakeholders.

Prevalence of motorcycle accidents among food delivery drivers and its relation to knowledge, attitudes, and practices in urban areas in Bangkok, Thailand.

Food delivery drivers are at increased risk of motorcycle accidents every year. This study investigated the prevalence of motorcycle accidents among food delivery drivers related to the knowledge, attitudes, and practices in urban areas in Bangkok, Thailand. This was a cross-sectional online survey on motorcycle accidents was distributed among food delivery drivers in urban areas in Bangkok, Thailand from February-March 2023. The study involved 809 participants aged 18 years. A binary logistic regression was conducted to test the association between variable factors and motorcycle accidents, and a Spearman's analysis was employed to test the correlations between motorcycle accidents and knowledge, attitude, and practice scores. The study found the prevalence of accidents associated with food delivery drivers was 284 (35.1%). The results of the binary logistic regression analysis found that those who drive on an average of more than 16 rounds per day were significantly associated with motorcycle accidents (OR = 2.128, 95%CI 1.503-3.013), and those who had followed improper driving practices were significantly associated with motorcycle accidents (OR = 1.754, 95%CI 1.117-2.752). The correlation analysis found the knowledge score positive significantly with the practice score (r = 0.269, p-value < 0.01) and the attitudes score positive significantly with the practice score (r = 0.436, p-value < 0.01). This study shows the knowledge level correlated with the practice score regarding such accidents. Therefore, our study needs more longitudinal study to identify which variable factors influence motorcycle accidents among FDDs. The current study suggests that the management of traffic safety on urban roads is significantly affected by food delivery services. Thus, this study can be used as baseline data to devise systematic measures to prevent motorcycle crashes of food deivery workers.

Seismic Hazard Microzonation Map for the Central Plain of Thailand

A study was conducted to investigate the seismic hazard microzonation of the central plain of Thailand, which is situated in an area with a thick quaternary basin. Unconsolidated sediments can lead to amplification of earthquake ground shaking at fundamental frequency and can cause a significant increase in damage to buildings. The research yielded significant results, including the development of a fundamental frequency map through the analysis of HVSR for 149 microtremor measurement sites. Subsequently, a Vs30 map was derived utilizing HVSR inversion techniques, and a soil classification map was constructed based on the NEHRP classification. The upper central plain along the Yom River and the Nan River had a low fundamental frequency of 0.3-0.5 Hz and low Vs30, which can be classified as soil type Class E. In the southern areas of Ayutthaya, Pathum Thani, and central Bangkok, an extremely low Vs30 of less than 100 m/s was observed, indicating soil class F or special soft soil. A comprehensive investigation was conducted on probabilistic seismic hazard analysis by considering the Vs30 sites condition for PGA, SA0.2s, and SA1.0s with a 2475-year return period. The northern region of the upper central plain and the western side of the central basin exhibit relatively high seismic hazards. Furthermore, the site effect significantly amplifies ground motion at the 1.0 second period, surpassing the earthquake-resistant design standard for buildings in Thailand by more than 5 times, particularly in the central region of the lower central plain.

Unlocking Urban Accessibility: Proximity Analysis in Bangkok, Thailand’s Mega City

Accessibility serves as the fundamental link for mode shifts, enabling access to activity areas and facilitating connections to other forms of travel. However, navigating the transportation network in urban areas of Bangkok, Thailand, reveals persistent inconveniences, discomfort, and safety concerns, thereby failing to adequately meet the needs of users. This study aims to examine urban accessibility, focusing on multi-travel connections to amenities and public transport. It focuses on understanding how the level of engagement of road users in social activities contributes to well-being by addressing proximity access through a multidisciplinary approach aimed at enhancing accessibility and integrating the built environment. The comprehensive and inclusive Accessibility by Proximity Index (API) is proposed as a tool to evaluate the level of access to essential services and activities for residents. Additionally, this study acknowledges the impact of the physical and utilization characteristics of urban space and active trajectories by considering various travel needs and daily route patterns. Consequently, the API can inform the development of planning and urban design strategies aimed at enhancing walkability and cycling as non-motorization infrastructures, thereby improving accessibility through active modes of transportation. It was observed that areas with a higher concentration of urban amenities exhibit greater accessibility by walking, cycling, and public transport, particularly in inner-city areas. Thus, envisioning a more sustainable and inclusive city with adequate development of public transportation access is essential in urban areas, prompting policy-level initiatives to enhance the environment and elevate the overall commuting experience.

Spatiotemporal distribution of hematophagous flies (Diptera: Muscidae) on beef cattle farms in Bangkok, Thailand.

A spatiotemporal investigation of hematophagous fly prevalence was conducted over a 1-year period on 12 beef cattle farms located in major livestock areas of Bangkok, Thailand, using Vavoua traps. The survey revealed 5,018 hematophagous flies belonging to Muscidae and Tabanidae, with the 3 dominant species identified as Stomoxys calcitrans (Linnaeus) (2,354; 46.91%), Musca crassirostris Stein (1,528; 30.45%), and Haematobia exigua de Meijere (922; 18.37%). The abundance of S. calcitrans per trap per week was significantly higher during the rainy season (45.64 ± 14.10), followed by the cold and dry seasons (6.39 ± 2.16 and 3.04 ± 1.27, respectively). The relative abundance of S. calcitrans reached the highest apparent density per trap per day (ADT) index of 9.83 in August 2022 during the rainy season. Subsequently, there was a rapid decline, and the ADT index dropped to nearly zero in December 2022 during the cold season. This low abundance continued through the dry months from March to May 2023. The higher rainfall and relative humidity could significantly contribute to the high relative abundance of S. calcitrans. In contrast, M. crassirostris and H. exigua showed population fluctuations that were not significantly associated with seasonal changes and weather conditions. Remote sensing data and spatial regression analyses using ordinary least squares regression showed the high spatial density of S. calcitrans in the north direction of the Khlong Sam Wa district during the rainy season; it shifted toward the south in the cold and dry seasons, corresponding with rainfall.

Garbage Detection using YOLO Algorithm for Urban Management in Bangkok

Garbage problems in urban areas are becoming more serious as the population increases, resulting in community garbage, including Bangkok, the capital of Thailand, being affected by pollution from rotten waste. Therefore, this research aims to apply deep learning technology to detect images from CCTV cameras in urban areas of Bangkok by using YOLO to detect images from CCTV cameras in urban areas of Bangkok, using YOLO to detect 1,383 images of overflowing garbage bins, classified into 2 classes: garbage class and bin class. YOLO in each version was compared, consisting of YOLOv5n, YOLOv6n, YOLOv7, and YOLOv8n. The comparison results showed that YOLOv5n was able to classify classes with an accuracy of 94.50%, followed by YOLOv8n at 93.80%, YOLOv6n at 71.60%, and YOLOv7 at 24.60%, respectively. The results from this research can be applied to develop a mobile or web application to notify of overflowing garbage bins by integrating with CCTV cameras installed in communities to monitor garbage that is overflowing or outside the bin and notify relevant agencies or the locals. This will allow for faster and more efficient waste management.

Occurrence and molecular characteristics of antimicrobial resistance, virulence factors, and extended-spectrum β-lactamase (ESBL) producing Salmonella enterica and Escherichia coli isolated from the retail produce commodities in Bangkok, Thailand

The incidence of antimicrobial resistance (AMR) in the environment is often overlooked and leads to serious health threats under the One Health paradigm. Infection with extended-spectrum β-lactamase (ESBL) producing bacteria in humans and animals has been widely examined, with the mode of transmission routes such as food, water, and contact with a contaminated environment. The purpose of this study was to determine the occurrence and molecular characteristics of resistant Salmonella enterica (S. enterica) (n = 59) and Escherichia coli (E. coli) (n = 392) isolated from produce commodities collected from fresh markets and supermarkets in Bangkok, Thailand. In this study, the S. enterica isolates exhibited the highest prevalence of resistance to tetracycline (11.9%) and streptomycin (8.5%), while the E. coli isolates were predominantly resistant to tetracycline (22.5%), ampicillin (21.4%), and sulfamethoxazole (11.5%). Among isolates of S. enterica (6.8%) and E. coli (15.3%) were determined as multidrug resistant (MDR). The prevalence of ESBL-producing isolates was 5.1% and 1.0% in S. enterica and E. coli, respectively. A minority of S. enterica isolates, where a single isolate exclusively carried blaCTX-M-55 (n = 1), and another isolate harbored both blaCTX-M-55 and blaTEM-1 (n = 1); similarly, a minority of E. coli isolates contained blaCTX-M-55 (n = 2) and blaCTX-M-15 (n = 1). QnrS (11.9%) and blaTEM (20.2%) were the most common resistant genes found in S. enterica and E. coli, respectively. Nine isolates resistant to ciprofloxacin contained point mutations in gyrA and parC. In addition, the odds of resistance to tetracycline among isolates of S. enterica were positively associated with the co-occurrence of ampicillin resistance and the presence of tetB (P = 0.001), while the E. coli isolates were positively associated with ampicillin resistance, streptomycin resistance, and the presence of tetA (P < 0.0001) in this study. In summary, these findings demonstrate that fresh vegetables and fruits, such as cucumbers and tomatoes, can serve as an important source of foodborne AMR S. enterica and E. coli in the greater Bangkok area, especially given the popularity of these fresh commodities in Thai cuisine.

Diversity of Epiphytic Subaerial Algal Communities in Bangkok, Thailand, and Their Potential Bioindicator with Air Pollution

Epiphytic subaerial algae represent an assemblage of micro-organisms widely distributed in terrestrial environments, including urban environments. Urban habitats present many challenges for the survival of photosynthetic micro-organisms, yet many species of subaerial microalgae have been reported from these environments, demonstrating a high tolerance to the harsh conditions of urban environments. In this study, the epiphytic subaerial communities of five parks in the urban area of Bangkok were studied using a metabarcoding approach (sequencing of the 23S rDNA marker), with the goal of unraveling their diversity and assessing potential bioindicators with levels of air pollution. Diversity indexes were determined for the algal taxa detected, which were separated into groups corresponding to different collection sites by cluster analysis. Relationships between taxa and air pollutants were analyzed by PCA and the Pearson correlation coefficient (r). The results showed a high diversity of epiphytic subaerial algae. We recorded 101 taxa belonging to the Cyanophyta (70 taxa), Chlorophyta (21 taxa), Charophyta (5 taxa), Bacillariophyta (3 taxa), and Eustigmatophyta (2 taxa). The most abundant taxon was Chroococcidiopsis sp. 1, for which up to 13,254 sequences/cm2 were recorded. The Shannon–Weaver index ranged between 1.37 and 2.51, the Margalef index between 3.84 and 4.75, and the Pielou index between 0.30 and 0.54. The similarity index was between 8.00% and 64.82%, according to the cluster analysis results for the three groups. The PCA indicated that all air pollutants affected the diversity and abundance of epiphytic subaerial algae. Cyanothece sp. 2 was negatively related to O3 and positively related to NO2 and CO and is suggested as a potential bioindicator of air pollution.

Assessment of phosphorus flow of canteen food waste in educational institutions in Bangkok area

This study was to investigate the occurrence of food waste in educational institutions and their current food waste management. Three educational institutions in Bangkok area were selected, and sampling were conducted for three days in a row for each institution. The results showed that the amount of food waste ranging from 20 to 198 kg/day, accounting of 40 – 90% of total waste. Most of food waste was eventually ended up in landfills. The phosphorus proportion of uncooked food waste (UCFW) was in the range of 0.09 – 0.29 mg P/g, while that of cooked food waste (CFW) was in the range of 0.53 – 0.76 mg P/g. Total phosphorus mass entering the waste management system was ranging from 8 to 141 g P/d, while loss of phosphorus was in the range of 1.5 – 13.5 g P/d. Under the composting scenario used in this study, the yield of fertilizer-like product ranged from 0.3 to 37.2 tons per year resulting in calculated cost saving as high as 391 USD per year. From this study, food waste separation was highly recommended to improve assessment of phosphorus flow and recovery. Expectation of phosphorus recovery for agricultural sector benefits should be prioritized.

Black Carbon and Traffic-Related PM2.5 in Bangkok Area

This study was to investigate level of black carbon (BC) in urban areas of Bangkok, Thailand. Hourly BC concentrations were measured at two stations (operated by PCD), i.e., Bangna station and Thonburi station (roadside) during dry season by using the aethalometer (Model AE-42). The averages of hourly BC concentrations observed were 5.1±2.9 and 4.3±1.9 µg/m3, respectively. The diurnal pattern of BC levels obtained from two stations exhibited two peaks of BC concentrations occurring in the morning (0500 to 0800 LST) and late evening (2100 to 2300 LST), which the late evening peaks were higher than the morning ones. The morning peaks of BC were evidently influenced by traffic condition, while the evening peaks were possibly related to traffic associated with meteorological effects. BC concentrations from roadside stations (Thonburi) were higher than those from Bangna station possibly due to less distance of sampling equipment from roads. There was some difference of BC concentrations observed between during weekday and weekends, particularly, at roadside station (Thonburi station). In addition, increase of diesel vehicles proportion, particularly in the nighttime, contributed to higher BC concentrations. The relationships among BC concentration, air pollutants (PM2.5), vehicle fleets and meteorological variables were found.

Co-designing a housing and livelihood toolkit with low-income older people for future housing in Klong Toey, Bangkok, Thailand

ABSTRACT The purpose of this article is to examine the co-design process of a research project which was implemented to support an initiative led by low-income older people in Klong Toey, Bangkok. The primary objective was to co-produce a design toolkit that can guide the development of live–work housing for low-income older people in Klong Toey. A three-day co-design workshop was held with local stakeholders to develop design alternatives for the prevailing live–work activities identified as a part of the field study. Within the framework of co-design methodology, the researchers engaged with the users as facilitators and translators to produce design options that informed the toolkit. The toolkit was developed under the overarching AgeingHood project, inspired by the unique housing and livelihood needs of the older people of Klong Toey, who often run small businesses from their own homes. It was conceived out of the understanding that ageing, housing and livelihood are interrelated aspects of the lives of low-income older people in this area of Bangkok. In addition to the toolkit, the project also led to impacts such as supporting residents’ live–work needs assessment and positive engagement and collaborative working with various local stakeholders.

The Effect of Earthquake on Temporary Structures during Bridge Construction with Different Column Heights

This research aims to study the effect of earthquakes on temporary structures during bridge construction with different column heights for analysis and evaluation of the damage to temporary structures known as “Launching Gantry” and bridge structures. The primary focus is on temporary structures used in bridge construction with spans of 45 meters and heights of 7, 19, and 28 meters. The research examines four different stages of bridge construction: a single-span bridge, launching the gantry to install the next span, preparing to hang prestressed concrete box girders, and hanging the prestressed concrete box girders. The study uses 12 models created with the midas Civil computer program and nonlinear time history analysis to simulate seismic acceleration in the Bangkok area during the construction stage with a return period of 39 years to determine the internal force and the deformation. As a result, the forces were compared to the resistance according to Eurocode standards to evaluate the damage. The results show that the bridge structure is undamaged, with only minimal deformation, but significant damage was found in the legs of the supports, particularly the front support. The flexural moment and axial force were 1.53 times greater than the resistive strength, and the leg experienced deformation in the transverse direction of the bridge up to 71 millimeters, or 1/77 of the leg height.

Modeling the effects of urban form on ventilation patterns and traffic-related PM2.5 pollution in a central business area of Bangkok

Traffic-related PM exposure is a significant concern in several cities. This study used ENVI-met simulation to perform the airflow and PM2.5 dispersions in Bangkok's central business district during summer. The impact of urban forms and traffic pollution on airflow and PM2.5 distributions was assessed using correlation analysis. Results showed that during summer, road traffic contributed to urban PM2.5 concentrations. Sky view factor and road area significantly affected wind speeds and PM2.5 concentrations, and these two parameters positively correlated. High wind speeds and PM2.5 concentrations were found in the urban main road, while those levels in the areas far from the road dropped by 50% due to building obstacles. Large open spaces (high sky view factor) could improve wind speeds in inner-city areas by 63%. Based on wind and PM2.5 performance classification, this study introduced new performance-based zoning, including five subzones with design recommendations. Urban planners and architects can use this information to improve pedestrian wind comfort and control air pollution dispersion from road traffic.

The Agrihood Design: Valuation of Ecosystem Services for NbS Visions in Peri-urban Housing Estate Development, Bangkok, Thailand

Nature-based Solution (NbS) designs increasingly are being implemented to reduce environmental impacts of urban development and enhance community resiliency to disruptions ranging from floods to climate change to Covid-19. But, the question remains, how do we assess the ecosystem service benefits provided by competing NbS designs in order to optimize such benefits? As such, the objective of this study was to develop and trial an assessment approach for the valuation of ecosystem services in a peri-urban area of Bangkok, Thailand. In our evaluations we considered the ecosystem service benefits of: i) water yield; ii) sediment yield; iii) nutrient yield; iv) carbon sequestration; v) urban heat island mitigation; vi) crop production; vii) habitat quality; and viii) aesthetics. Our ecosystem services valuation approach was tested using three case studies in peri-urban Bangkok, Khlong Luang, Pathum Thani: i) an existing new single detached housing development in the area; ii) an area in its currently undeveloped, open and scrub forest state; and iii) the same area as (ii), but theoretically developed using an Agrihood design concept. The valuation approach included a combination of mathematical modeling for the water, sediment, and nutrient yield ecosystem services and an empirical, data-driven approach for urban cooling, carbon sequestering, crop production, habitat quality, and aesthetics. While the existing housing development design was meant to be relatively green and nature-oriented, the Agrihood design outperformed it in every ecosystem service category, including habitat quality and aesthetics. The Agrihood design also had lower sediment and nutrient yields and mean concentrations as compared to current (natural) conditions at the site, which is attributed to the inclusion of constructed wetlands in the design for the main drainage canal. This work represents a good preliminary step in establishing a local scale ecosystem services valuation framework for urban areas in a tropical climate, but additional refinements to the indicator determinations are needed.
