Air Passengers' Risk of SARS-CoV-2 Infection with a 14-day Quarantine and Accuracy Assessment of a Symptom-based Screening System at an Airport.

This study aimed to validate the risk of SARS-CoV-2 infection, identify infection risk factors among air passengers subject to a 14-day mandatory quarantine, and evaluate the accuracy of mass symptom-based screening criteria at an airport. This retrospective cohort study analyzed data from 116,004 air passengers who entered Thailand through Suvarnabhumi Airport in Bangkok from April to September 2020. The incidence of SARS-CoV-2 infection, risk characteristics, and accuracy indices of symptom-based screening were calculated. The overall incidence of SARS-CoV-2 was 0.5%, or 540 infections per 100,000 air passengers. Identified risk factors included sex, nationality, continent of departure, on-arrival screening results, and month of travel. Positive screening results indicated a higher risk and positive likelihood ratio for SARS-CoV-2 infection. However, the on-arrival screening criteria demonstrated low sensitivity and area under the receiver operating characteristic curve. The current study confirms previous findings that the risk of SARS-CoV-2 infection during air travel is low. However, this might result from strict pre-departure screening and the SARS-CoV-2 test requirement for arriving passengers. The symptom-based screening criteria used upon arrival showed a low probability of identifying positive cases, suggesting that incorporating additional criteria could help detect asymptomatic infections. The integrated screening and quarantine model proved effective in preventing the spread of the virus into local communities.

Numerical Simulation of Effects of Previous PVD Treatment on Second Vacuum-PVD Improvement

The influence of the initial improvement through prefabricated vertical drains (PVD) and surcharge embankment on the second improvement by vacuum PVD has not been comprehensively explored in the existing literature. The expansion of the Second Bangkok International Airport (Suvarnabhumi Airport) underwent initial treatment with PVD and surcharge, followed by further soft ground improvement with vacuum PVD, which serves as a valuable case study for understanding the impact of the initial PVD improvement. This study highlights the effects of the initial PVD improvement through a comparison of two case studies: the first improvement by vacuum PVD on Taxiway Extension D at Zone 27 and the second vacuum PVD improvement on the Third Extension North at Zone 7. Extensive back analysis results reveal significantly higher flow parameters and reduced settlements for the second improvement at Zone 7 compared to the first improvement at Zone 27. The water contents, void ratios, and compression indices decreased while the undrained shear strengths and maximum past pressures increased. These results demonstrated the effectiveness of the vacuum PVD improvement with a modified field-distributed air-water separation system. Numerical studies further corroborated these findings and confirmed the observed crack patterns at the surface resulting from inward lateral movement.

Characteristics of community responses to airport noise around Bangkok International Airport

A social noise survey is a study of the community's response to noise. Data from a 2014-2015 noise survey of communities living around Bangkok International Airport is considered a spatial study that is important for the long-term planning of the airport development plan to prevent noise problems from aircraft operations. This paper presents the nature of survey data on airport noise from people living around Suvarnabhumi Airport over a decade after the airport's opening in 2006. It is now planned to expand the airport's capacity to handle more air traffic volume through runway expansion and passenger terminal expansion. The cross-sectional study is thought to be useful in future airport noise planning to avoid severe aircraft noise problems. In addition, it was an appropriate time to collect data from the field as a baseline for future airport noise management before expanding the capacity to handle more air traffic by adding more runways and passenger terminals.

Changes in Connectivity for Major Asian Airports - Europe and Post-Pandemic Improvement Suggestions

The aviation transport volume in the Asia-Pacific region continues to grow, with many airports aspiring to become aviation hubs. However, in 2020, the aviation industry faced significant disruptions due to the COVID-19 pandemic. In light of this, this study aims to explore the pre-pandemic and post-pandemic airport competitive advantages of major Asian airports. This study selected six major airports, focusing on the quality of transit services and the number of transit flights. Specifically, the study examines two perspectives: quantity (QVC) and quality (QCI), utilizing connectivity indices such as Hub Connectivity Performance Index (HCPI) and Hub Efficiency Index (HEI). Based on connectivity analysis results, Singapore Airport, Suvarnabhumi Airport, and Kuala Lumpur Airport hold a leading position in HEI due to their geographical advantages. These airports should continue to develop Southeast Asia - Europe routes. Hong Kong International Airport follows closely in connectivity, but its flight numbers were significantly affected by the pandemic and the anti-extradition bill protests factors. Efforts to expedite the recovery of the European market are recommended. Incheon Airport benefits from the rapid development of low-cost aviation in recent years, expanding routes and flight frequencies, resulting in a continuous increase in QVC. However, it needs to enhance transit efficiency to elevate its HEI. Taoyuan Airport lags behind the aforementioned airports in both QVC and HEI. To attract more transit passengers, it should increase flights in this market.

Cosmic Radiation Exposure of Aircraft Crew under the Impact of Geomagnetic Vertical Cutoff Rigidity: Case Study of International Flights from Suvarnabhumi Airport, Thailand

Aircrew members are occupationally exposed to higher levels of galactic cosmic radiation than the general population in most parts of the world. The International Commission on Radiological Protection (ICRP) is concerned by the exposure of aircrews to cosmic radiation. The cosmic radiation intensity in the Earth atmosphere depends on many factors, e.g., the solar activity, altitude, and geomagnetic vertical cutoff rigidity on Earth. This study aimed to calculate the occupational radiation dose for aircraft crews during the solar minimum and maximum on fl ights from Suvarnabhumi Airport (BKK), Thailand, to 11 destinations worldwide. Based on the Monte Carlo simulation code of CARI-7 and JISCARD GUI, the cosmic radiation doses on fl ights was calculated. The maximum dose of a roundtrip fl ight (Bangkok–Helsinki) during the solar minimum condition was approximately 97.4 μSv (CARI-7) and 84.7 μSv (JISCARD GUI). The maximum radiation dose corresponded to 110 and 20 roundtrips for general aircraft crew and pregnant crew, respectively. This fi nding indicates that the polar-latitude region of Helsinki fl ights at low vertical cutoff rigidity ranges is of concern in terms of high-exposure cosmic radiation. The uncertainty associated with the result of the two codes was less than 30%. Therefore, the results were in reasonable agreement, and the codes could be used to calculate the exposure of aircraft crew to cosmic radiation.

IMPACT OF AIRPORT SERVICE QUALITY, IMAGE, AND PERCEIVED VALUE ON LOYALTY OF PASSENGERS IN SUVARNABHUMI AIRPORT SERVICE OF THAILAND

Suvarnabhumi Airport is a gateway to Thailand and Asia. It attracts inbound-, outbound- and transit passengers. The objectives of this study were to develop an airport service quality, image and perceived value framework for the loyalty of passengers and to study the direct, indirect and total effects of the factors that influence the loyalty of passengers who used the service at Suvarnabhumi Airport. This quantitative research method uses the questionnaire as a tool for collecting data from 400 passenger samples. According to the Structural Equation Modelling analysis, airport service quality, image and perceived value have had a positive effect on loyalty that airport service quality mainly has an impact on passenger loyalty. There are four latent dimensions of airport service quality, namely, essential services; comfort, convenience and enjoyment; security, customs and passport control; and special facilities, that can help develop loyalty. Perceived value and image on airport administration and management had a significant direct effect to passenger loyalty. Improving these facotrs in order to attract passenger interest and attention can lead to the development of airport organization performance, and to increase competitiveness as an aviation hub in this region.

Detection of Orthopedics Implants in Vivo by Hand-Held Metal Detectors

Objective: To assess rates of detection of various orthopedic implants by airport detectors with the new security sensitivities. Materials and Methods: Two hundred sixty-one volunteers with 386 implants were asked to be scanned by a hand-metal detector model Garrett SUPER SCANNER™. The sensitivity was set equivalent to the Suvarnabhumi Airport Transportation Security Administration setting for regular security. Results: Of the 386 implants in 261 patients who were screened, 231 (60%) were trauma hardware, including intramedullary nails, plates, screws, and Kirschner wires, and 155 (40%) were arthroplasty implants. Three hundred thirty-five (86.78%) of the 386 implants were detected by the metal detector. The overall rate of detection was 99.35% for prosthetic replacements and 98.05% for plates. All the total knee replacements and 95% of the total hip replacements were detected. The Kirschner wires were not detected. The overall detection rate was 92.54% for implants in the lower extremity, 55.73% for those in the upper extremity, and 93.33% for those in the spine. The detection rate for implants in the lower extremity was two times higher than the implants in the upper extremity and equal for implants in the spine. Conclusion: Most of the orthopedic implants may be detected by hand-metal detector model metal detector used at commercial airports. Total joint prostheses, nails, and plates will routinely set off the detector, whereas screws and wires are rarely detected. Cobalt-chromium and titanium implants are more likely to be detected than stainless-steel implants. Keywords: Orthopedic Implant, Hand-Held Metal Detector, Security

Comparative analysis of efficiency for major Southeast Asia airports: A two-stage approach

Within the past few years, the economy of Southeast Asia has been expanding rapidly with the rise in demand for air transport services. International airports are important driving forces for Southeast Asia countries' economies. Therefore, the competitive ability of these airports is very essential in terms of development and competitiveness within the region. This paper investigates the capabilities of these airports by a two-stage approach. The strengths and weaknesses of each Southeast Asia airport are evaluated by Data Envelopment Analysis – Slack-Based Measurement (DEA-SBM) in the first stage. This is a non-parametric approach to measure the efficiency of 9 major airports in the area including Changi Airport (Singapore), Suvarnabhumi Airport (Thailand), Kuala Lumpur Airport (Malaysia), Soekarno Hatta Airport (Indonesia), Ninoy Aquino Airport (the Philippines), Noi Bai Airport, Tan Son Nhat Airport (Vietnam) and Guangzhou Baiyun Airport (China), Hong Kong Airport (Hong Kong). In the second stage, Tobit regression is used to estimate the influence of multiple factors toward the efficiency of each airport. By generalizing and comparing two stages, the analysis allows us to evaluate each airport's efficiency in seven years, as well as the impact of multiple factors in one airport's performance. The implications for improvement are also obtained and discussed.

Operational Challenges of the Bangkok Airport Rail Link

The airport rail link (ARL) was launched in 2010 as a premium rail transit service between the inner city of Bangkok and the airport. In 2014, the express service was canceled due to its unpopularity and transformed into the commuter service. In 2017, the new extended service concept was introduced under the three airport links project. Under this new concept, both ARL and high-speed trains will run on the city line section between Don Mueang and Suvarnabhumi Airports. This paper focuses on the use of a microsimulation model to identify the challenge of mixed-service operations, with regular and express trains running on the city line section. The simulation model allows investigation of hypothetical situations and construction of feasible timetables. The model can identify sections where special attention is needed, such as speed reductions, extended dwell times, or delayed departures. During the peak hour, the results suggest that the regular ARL should run with a 10-min headway and the high-speed one line with a 20-min headway, as an alternative solution. This results in fewer train numbers and less additional running time. Simulations indicate that the high-speed train is not efficient, as it consumes 2–3 times higher energy, while offering little time saving compared with the ARL city train. In addition, the Suvarnabhumi Airport extension track layout needs to be carefully considered, since the Suvarnabhumi Station area is a bottleneck liable to disruption.

Educational and digital tools as factors of service quality increase in Thailand 4.0 era (the case of Suvarnabhumi Airport, Bangkok)

Currently, Thailand implemented the project Thailand 4.0 essentially highlighted on better performance on human resource as well as an information technology management. However, service quality is the key to create the business differentiation as well as to elevate a superior level of market competitiveness. The aviation industry is one of the most intense competitive industry, therefore, passengers’ satisfaction on airport service quality and its’ efficient facility management is the most important factor that can create business differentiation and influenced a sustainable industry accordingly. This paper seeks to investigate the (1) factors that affect service quality and (2) passengers’ satisfaction of Suvarnabhumi airport in Thailand 4.0 era. Where the concept of Importance-Performance Analysis (IPA) has been implemented in this research, the results show that passenger’s expectation on service quality was higher than the services that passengers received in many areas. However, from 150 questionnaires that have been released, the research results indicated that most of the respondents placed the highest satisfaction on the quality of internet and wireless connectivity service as the top priority at Suvarnabhumi Airport, whereas the lowest satisfaction is placed on the service quality of an immigration process where the effectiveness of human resources management is the key element affecting the service quality. Moreover, there is a recommendation on the self-check-in-counter and the processing of this service that needs to be modernized and promote passengers to use this technology widely. Hence, to enhance the airport service quality toward Thailand 4.0, the technology should be taken into account at every level to increase passengers’ satisfaction throughout the passenger’s arrival, departure and transit process accordingly.

Evaluation of air cargo connectivity and policy in Thailand

This study evaluates the air cargo connectivity of Suvarnabhumi airport in Thailand by developing an air cargo connectivity model that includes new air cargo operation deficiency factors. Our model is developed and extended from the NetCargo model and assesses the impact of air cargo operation deficiency of airports/airlines on their air cargo performance. The analysis shows that short-shipped cargo is the result of air cargo operation deficiency and has a big impact on overall air cargo connectivity. The finding presents a big difference between the results from both models. This result shows significant differences in airport strategy and planning policy. The finding suggests that our proposed model is practically suitable for the Asian region. We also discuss policy recommendations, such as the improvement of e-AWB, to improve the ability of air cargo transport in Thailand to prepare and cope with future demand.

Analysis of Quiet Time Vertical Ionospheric Delay Gradients Around Suvarnabhumi Airport, Thailand

AbstractGlobal Navigation Satellite System (GNSS) is vital to aircraft navigation at many phases of flight. To extend its use to the approach and landing phases, ground‐based augmentation system is an important on‐the‐ground technology to reduce the positioning errors. However, nonuniform spatial ionospheric delays need to be assessed during ground‐based augmentation system planning at each airport, particularly, in equatorial and low‐latitude regions. In this work, we analyze the statistics of ionospheric delay gradients around Suvarnabhumi airport, Thailand. The ionospheric delay gradients are estimated using single‐frequency code and carrier phase observation through the Kalman filter. To increase the success of the ratio test, the satellite elimination technique is then proposed. Based on the analysis between 2013 and 2016, we find that the background ionospheric delay gradients during equinox are higher than solstice, especially during September equinox 2013 when the gradients are about 9 mm/km. Moreover, the ionospheric delay gradients are more variable during daytime than nighttime.

Transient Current Behaviour during Multiple Lightning strokes on Multiple Unit Trains

This paper studies transient current behaviour during multiple lightning strokes on Multiple Unit trains in pantograph. 2×25 kV AC, 50 Hz Catenary Contact System on double-track elevated railway system which connects Phayathai BTS station in the Centre with Suvarnabhumi Airport in the East of Bangkok was used in the study. This paper investigates effectively in order to reduce breakdown due to overvoltage condition caused by transient current during multiple lightning strokes. The magnitude, front times and tail times of multiple lightning strokes were studied. The assumption of studies based on the return multiple lightning strokes current ranging 1–200 kA, front time of multiple lightning strokes between 1–3 μs, elevated pole resistance of 50 Ω and grounding resistance of 5 Ω. The Catenary Contact System on elevated railway system with Multiple Unit trains and multiple lightning strokes were modelled in ATP-EMTP software. The effect of varying front time of multiple lightning strokes, transient current and mast induced voltage were studied in simulations. Simulations showed that the peak amplitude of mast induced voltage tend to increase when the negative multiple lighting strokes on Multiple Unit trains in pantograph at elevated pole than it is between elevated poles in different front times.

Flight attendant's knowledge sharing, innovative work behaviour, and new service development

New service development is an important topic for decision-makers in service firms, since continuous innovation is expected to pay off. We argue that flight attendants' knowledge sharing and innovative behaviours can enhance new service development performance. In addition, flight attendants' perceived behavioural control can enhance their knowledge sharing and innovative behaviours. Furthermore, we argue that organisational support and attitudes towards sharing knowledge also increase flight attendants' knowledge sharing and innovative behaviours. Data were collected from 328 flight attendants representing eight airline companies at Suvarnabhumi Airport, Bangkok, Thailand. The results showed that organisational support and positive attitude to sharing affected knowledge sharing and innovative work behaviour, whereas perceived behavioural control has been found to affect only knowledge sharing behaviour. In addition, flight attendant's knowledge sharing had a positive effect on innovative work behaviour and new service development.
