Optimize Airline Service Policy Based on Airline Passenger Satisfaction Data Analysis

As the preferred means of transportation for long-distance travel after the epidemic, whether an airline can stand out among its peers is deeply related to whether it can satisfy passengers, and the service quality of an airline can significantly affect passenger satisfaction. In this paper, random Forest is applied to judge the correlation between satisfaction and different service factors, and several factors that have the most significant impact on satisfaction are selected. The results show that the influence degree of Online. boarding, Inflight. wifi. service is significantly higher than other factors. Then, Legroom service, Inflight entertainment, departure-arrival time convenience, and Seat comfort are four factors with significant influence. Therefore, this paper believes that airlines should provide convenient online registration, rich flight entertainment activities, and comfortable seat space to improve passenger satisfaction under the premise of ensuring that their costs do not change much. In this way, airlines can greatly improve their competitiveness to attract and retain more loyal passengers.

Neck posture and muscle activity in a reclined business class aircraft seat watching IFE with and without head support

The purpose of this study is to research if a headrest benefits the comfort of the passenger and lowers muscle activity in the neck when sitting in a reclined (slouched) posture while watching in flight entertainment (IFE) in an aircraft business class seat.No significant differences in muscle activity in the musculus sternocleidomastoid and musculus trapezius pars descendant were found between the conditions with headrest and without headrest. A significant difference in expected comfort rating was found. Subjects indicated they expect to experience more comfort with a headrest when watching IFE for a duration of two movies during a long-haul flight. This study also found a significant difference in posture. In the condition without headrest the head was more upright compared to the condition with headrest.The lack of significant difference in muscle activity and the significant difference in posture may indicate that humans tend to look for a head position that is neutral, in the sense of minimal muscle effort. This study shows that the use of a headrest may benefit the comfort experience of the passenger during flight. However, further research is necessary on the design of the headrest and the long-term effects of head support on comfort, discomfort, muscle activity and fatigue for watching IFE in a slouched posture.

Invasive fungal infections

2012, London. 22nd European Congress of Clinical Microbiology and Infectious Diseases (ECCMID). With over 300 million serious fungal infections worldwide, we need to be aware of the size of the problem (http://www.fungalresearch trust.org/HowCommonareFungalDiseases2.pdf) and the need for more diagnostic tools and treatment options. Given that the mortality of candidemia and septic shock has been shown to increase by 7.6% with every hour of delay in therapy initiation (Kumar A et al. ICAAC 2007, poster K-2174), a timely diagnosis is literally vital. A classical approach can provide a diagnosis within 72 hours, through microscopy and cultures. A newer approach based on polymerase chain reaction (PCR) and (1,3)-β-D-glucan (BDG) can shorten the time to diagnosis, but we still have a long way to go in finding diagnostic algorithms with improved sensitivity and specificity. A recent study by Nguyen et al. (Clin Infect Dis. 2012; 54(9):1240-8) showed that PCR and blood cultures identified the same Candida species in 82% of patients and that PCR had a sensitivity of 80% in diagnosing invasive candidiasis, compared with 56% for BDG. When combining blood cultures with PCR or BDG, the sensitivity increased to 98% and 79, respectively. Awareness of fungal infections is of utmost importance because, naturally, the first step to a diagnosis is thinking about a possible infection. Fungi have not always been high on the list of possible etiologies but in modern times they definitely should be considered given the increasing life expectancy, the high number of comorbidities, with diabetes ranking high as comorbidity and cofactor for invasive fungal infections. When discussing fungi, we should be aware of their worldwide distribution, particularly since travel appears to increase exponentially. News from last week’s air flight entertainment magazines pointed out that one day traffic in 2012 is equivalent to one year worth of travel in 2007. Therefore, travel medicine also plays an increasingly important role in diagnosing and treating fungal infections.

Ku Band Hemispherical Fully Electronic Antenna for Aircraft in Flight Entertainment

The results obtained in the frame of the ESA activity “Advanced Antenna Concepts For Aircraft In Flight Entertainment” are presented. The aim of the activity consists in designing an active antenna able to guarantee the Ku band link between an aircraft and a geostationary satellite in order to provide in flight entertainment services. The transmit-receive antenna generates a single narrow beam to be steered electronically in a half sphere remaining compliant with respect to stringent requirements in terms of pattern shape, polarization alignment, EIRP, G/T, and using customized electronic devices. At the same time, the proposed solution should be competitive in terms of cost and complexity.

Accelerometer based calf muscle pump activity monitoring

Long distance travel is associated with increased risk of deep vein thrombosis (DVT). There is an increased risk of travel related DVT in passengers with a predisposition to thrombosis. Assisting blood circulation in the lower limb will reduce the risk of DVT. Leg exercises are recommended as a DVT preventative measure while flying but this fails to account for a passenger who is distracted by in flight entertainment or who falls asleep for an extended period. A method for monitoring calf muscle pump activity using accelerometers has been developed and evaluated. The proposed technique could be used to alert the traveller that there is a need to exercise their calf muscle, thus reducing the risk of DVT.
