“…Electrodes are attached to an EEG cap which is multi-channels (16 channels) to catch the signals of gamma, beta, alpha, theta, and delta from the various areas of the brain and different frequencies of these signals are merged with the amplifier to draw each measured potential on the screen. In Figure 3(b), the wavelength ranges of these different frequencies are given, and digital recording is made for physiological characteristics 17 .…”

Pilots who have completed successfully all the tests of cognitive and personality psychology have a strong commitment to their movements, and they influence their neural stimulation, such as the ability to acknowledge the right steps to follow in their tasks or dangerous situations. One of the branches of Aviation Psychology is dealing with the physical and mental effects of flight on aircrew personnel and passengers. Astronomical events, such as geomagnetic storms (GSs) that have a disruptive effect on Earth’s magnetosphere in certain periods, will cause negative effects on aircrew personnel and passengers. This article describes the expected damage to the different areas of the brain and nervous system in short- and long-term periods caused by the effects of GSs, based on the results of previous studies on GSs and neurophysiological studies. This is a very important topic for neurophysiological studies of pilots when we consider that aircraft accidents that may be geomagnetic in origin accounted for 26.36% of the total accidents which coincide with the days of GSs. Decision-making and judgment problems, abnormal attitudes such as anger, fearlessness, temerity, self-confidence, etc., decreasing problem-solving abilities, organization capabilities, and instantaneous decisions are the short-term changes while developing cancers of the brain, testis, bladder, breast, colon, melanoma, and Hodgkin’s type, in addition to Alzheimer’s and dementia diseases, hypoglycaemia, stroke, epileptic seizures, insomnia, stomach bleeding, appendicitis, hernia, asthma, and severe spinal pains can be lead in the long-term changes. We mentioned the psychological and medical application method of EEG in our article since it is the best technique that allows us to see the effects of these storms in the laboratory environment. This is because, the aircrew personnel and passengers flying at high latitudes will experience the effect of the GSs directly, whereas the response of the pilot, flight crew, and passengers flying in the middle latitudes, to these effects, can be measured only with tests in the laboratory environment. This paper has also special importance for the aviation literature because a theoretical recommendation regarding the possible laboratory environment for EEG measurements and application procedures necessary to investigate these effects is also presented.

“…Human EEG potentials often occur in numerous clearly pre-defined bands, such as 0.5-4 Hz (delta), 4-8 Hz (theta), 8-13 Hz (alpha), 13-30 Hz (beta), and >30 Hz (gamma), and are aperiodic, unpredictable oscillations with intermittent bursts of oscillations [6]. These oscillations' sources are billions of In Figure 2 [7], examples of these EEG cycles are displayed. Because they produce results that are simple to comprehend, contemporary machine learning methods for biomedical engineering, such as CNNs, are immediately applicable to one-dimensional biosignals.…”

BackgroundThe Sri Lankan public health care system provides free health care. Psychiatric services in the public sector have expanded over the years to reach the whole country. Currently, the cost of care per patient in a government hospital is not calculated directly. AimsTo assess the total in-ward expenditure, expenditures incurred in different cost heads, average per patient cost and cost per patient day in a psychiatry unit at Teaching Hospital, Anuradhapura, Sri Lanka. MethodsA financial audit was carried out at Teaching Hospital, Anuradhapura. All patients admitted for in-patient psychiatry care from 1st to 30th of September 2019 were included. Data were collected retrospectively from patient documentations and hospital accounting using a data extraction form. ResultsNinety patients, 48 (53.3%) females and 42 (46.7%) males, were included in the study, with 711 in-patient days. The average length of stay was 7.9 days. The mean age was 39.8 years, ranging from 16 to 75 years, and most were married (55.6%). Schizophrenia and depressive disorder were the commonest diagnoses. The total cost per month in the psychiatry unit was LKR 3 321 050.60, with an average of LKR 110 701.70 per day. The average cost per patient per day was LKR 4 670.96. Staff wages accounted for 56.27% of the total expenses, and medications and other consumables accounted for 13.01%. ConclusionsClinicians can carry out cost analysis with data available to them. The results can be used to efficiently allocate resources from the total budget in the given institution, and to implement cost reduction plans to use limited resources effectively.
