Opis:
Evaluating synoptic conditions and the incidence of fog cases as well as number of days with fog across a large spatial spectrum such as atmospheric circulation and comparing results to local scale analyzes will help to accurately identify conditions conductive to formation of fogs on the territory of Poland. The aim of the study is to analyze the time of fog formation during the day, fog duration, and the extent of limitation of the horizontal visibility. Data coded in METAR (Meteorological Aerodrome Report) messages was used to perform the analysis of synoptic from 8 stations located at the largest airports in Poland. In the analysis, the main criterion was the number of cases when horizontal visibility limited below 1 km – number of fogs. Results show that there is a clear, seasonal pattern of fog frequency for all stations in this study. For a majority of stations, the minimum number of fogs occurred during the summer months and the maximum number of fogs was observed in October and November. The probability of fogs in the cold half of the year, during the anticyclonic circulation, is slightly higher than during cyclonic circulation and is connected with meridional air advection. In the warm half of the year the probability of fogs during cyclonic circulation increases. Fog duration in most cases did not exceed 3 hours for all stations. At the stations analyzed, fog most often limits the horizontal visibility to 500 m, but there are seasonal differences in the frequency for separated ranges of horizontal visibility.

Opis:
The evaluation supports operational and strategic decision making in the organisation. In order to make proper decisions, the management staff must fully understand recommendations and indications resulting from the evaluation. The aim of the article is to analyse the level of the readability of the text used in the evaluation reports of the international and Polish strategic research programmes in the area of technical innovations. The text simplicity was measured with the use of the Gunning Fog Index. The results of the analyses show that the language of evaluation reports could be comprehensible mainly for people with at least higher education certificates, which means that in many organisations the evaluation recommendations are not taken into consideration, as they are simply not understood by the management staff, whose professional skills do not necessarily go with high level of formal education.

Opis:
The unpredictable and huge data generation nowadays by smart devices from IoT and mobile Crowd Sensing applications like (Sensors, smartphones, Wi-Fi routers) need processing power and storage. Cloud provides these capabilities to serve organizations and customers, but when using cloud appear some limitations, the most important of these limitations are Resource Allocation and Task Scheduling. The resource allocation process is a mechanism that ensures allocation virtual machine when there are multiple applications that require various resources such as CPU and I/O memory. Whereas scheduling is the process of determining the sequence in which these tasks come and depart the resources in order to maximize efficiency. In this paper we tried to highlight the most relevant difficulties that cloud computing is now facing. We presented a comprehensive review of resource allocation and scheduling techniques to overcome these limitations. Finally, the previous techniques and strategies for allocation and scheduling have been compared in a table with their drawbacks.

The article concentrates on the way in which face is presented in the first ‘Hitchcock Picture’ – The Lodger movie. In this text, face is understood as a set of elements that determine identity, but also have the potential for changes. Starting from the drawing of an unsuccessful shot from the movie and referring to its full title (The Lodger – A Story of the London Fog), the author focuses not only on face, but also on the role of fog in presenting the face of the city and constructing the face of the title character. Alfred Hitchcock’s decisions concerning the manner of presenting face are analyzed in the context of Béla Balázs theory and German film expressionism.

Opis:
The global demand for water has been growing rapidly in the last decade with a global population growth rate of 1.1% p.a., which is equivalent to 81 million people per year. Southeast Asian countries are facing severe water scarcity challenge due to their location in the tropics. In 2018, the Sumba Island experienced the highest temperature of 36°C and lesser rainfall of 911.1 mm3 per year and it was classified as a long dry island prone to drought due to dry winds from Australian desserts. This paper focuses on the perceived effect of water scarcity on livelihoods in the Mandahu Village, Indonesia, due to climate change. Sampling and survey covered rural households and the findings showed that the average household of 4 to 8 people consumed around 250 dm3 of water per day. The community relied on two main sources of clean water from two main springs. However, the prolonged dry season from May until December every year results in major challenges to access water and eventually affect the agricultural productivity. Hence, the feasibility of the fog collection technology has been investigated from technological, economic and social points of view as a reliable and cost-effective source of water. The outcome of this work will produce a feasibility statement for fog-to-water as an alternative solution counteracting water scarcity in the Sumba Island, a solution which can be replicated in other climate change stricken hot spots in Southeast Asia.

The purpose of this study is to evaluate the effectiveness of functional neuromarker- based electroencephalographic training with neurofeedback (EEG-NFB) for a patient with dysexecutive syndrome following neurosurgical operation of two brain aneurysms of the left and right middle cerebral artery (MCA) detected after COVID-19 disease. A right-handed, 56-years-old, not vaccinated, patient, became infected with SARS- CoV-2 and contracted COVID-19 with the manifestation of respiratory symptoms, high fever, dyspnea and low saturation of 79% Sa02. She was hospitalized at the Infectious Disease Unit, where a positive RT PCR test for COVID-19 was confirmed. The acute phase of COVID-19, during which oxygen therapy was administered, lasted two weeks and was complicated by brain fog and transient hypertension (175/100). There were no signs of focal damage to the central nervous system. She was discharged home in a good general and neurological condition. After returning home, the patient was unable to cope with daily functioning, as she said her brain fog continued to persist, manifesting itself as executive dysfunction. Eight weeks after the infection, the patient's neuropsychiatric condition worsened. On CT and MRI examination of the cerebral vessels, she was diagnosed with the presence of two aneurysms located on the left and right middle cerebral arteries (MCA). She was operated on at the Department of Neurosurgery and Neurotraumatology, where a pterional craniotomy and clipping of both brain aneurysms was performed. The Yasargil titanium clip was placed on the aneurysm neck. During the surgery procedures, performed two months apart, there were no signs of a history of subarachnoid haemorrhage and the post-operative period was uneventful, except for a drooping right-eye eyelid (after the second surgery) with a tendency to improve. Each time, the patient was mobilized and walked independently and was discharged home in a good general condition, with no neurological symptoms, except for executive dysfunction. Approximately five months after the SARS-CoV-2 infection (four weeks after the second surgery), her executive dysfunction worsened. Neuropsychological testing using Mindstreams™ Interaction Computer Tests revealed moderate Dysexecutive Syndrome (DES), while neurophysiological testing using qEEGs, ERPs and sLORETA tomography, a functional neuromarker of frontotemporal area dysfunction. The EEG pattern was characterized by excessive, slow (about 6 Hz) activity in frontotemporal areas, which indicated the progressive loss of cognitive control over time. The patient was offered an electroencephalographic training protocol with neurofeedback (EEG-NFB) based on the detected functional neuromarker, which reduced DES. The improvement achieved during therapy was statistically significant [compared to the normative database (Human Brain Index, HBI)]. In effect, the patient's quality of life improved, as she herself pointed out. Her symptoms of brain fog and DES disappeared and she returned to her previous work as a waitress. The Human Brain Index (HBI) methodology can be successfully used in the neurodiagnosis and implementation of individualized electroencephalographic training with neurofeedback (EEG-NFT) for patients with executive dysfunction after contracting longCOVID.

Opis:
Celem pracy jest określenie wpływu cyrkulacji atmosfery na występowanie mgieł na wybranych lotniskach w Polsce. Wykorzystano dane z okresu 1981-2015, obejmujące liczbę godzin z mgłą w poszczególnych dniach na stacjach w Szczecinie, Gdańsku, Poznaniu, Warszawie, Wrocławiu, Krakowie i Rzeszowie. Typy cyrkulacji atmosferycznej zostały opisane zgodnie z typologią J. Lityńskiego. Dodatkowo wykorzystano dane uzupełniające, obejmujące Numeryczny Model Terenu (DEM), mapy sieci rzecznej i zbiorników wodnych w Polsce oraz mapę pokrycia terenu CORINE Land Cover 2012. Z przeprowadzonych analiz wynika, że istotną rolę w występowaniu dni z mgłą odgrywają kierunki adwekcji powietrza. W większości przypadków najwięcej dni z mgłą występowało podczas adwekcji powietrza z kierunków południowych, a najmniej z północnych, niezależnie od pory roku. Zróżnicowanie przestrzenne występowania mgły w określonym typie cyrkulacji jest spowodowane między innymi wpływem warunków lokalnych. Największy wpływ wykazują rzeźba terenu i obecność zbiorników wodnych.
The aim of this paper is to examine the influence of atmospheric circulation on the occurrence of days with fog at the airports in Poland. The data included the number of hours with fog on particular days in the period of 1981-2015 on the stations in Szczecin, Gdańsk, Poznań, Warszawa, Wrocław, Kraków and Rzeszów. The study uses the circulation typology by J. Lityński. Additionallny, Digital Elevation Model, map of rivers and water reservoirs in Poland and land cover map CORINE 2012 were used in this research. The occurrence of days with fog in particular circulation types was assessed with the frequency and conditional probability. It was found that the directions of air advection play an important role in the occurrence of days with fog. In most cases the most days with fog occurred during air advection from southern directions and the least from northern ones. The spatial diversity of fog occurrence in a given type of circulation is caused by the influence of local conditions. The strongest influence is exerted by the relief and the presence of water reservoirs.

Opis:
This article reviews some very recent publications pertaining to the long-term neuropsychological effects of COVID 19 (neuroCOVID). Although such publications are now appearing in large numbers on a daily basis, we still do not have enough data of sufficient quality to enable any firm conclusions to be reached. At this point, then, the authors determined to consider the main questions that have emerged so far, as we wait for the results of more thorough research in the future. The article takes up three main questions: (1). What is the etiology and pathomechanism of the neuropsychological symptoms caused by SAR-CoV-2 infection, and what is the prognosis? (2). Of the reported symptoms, which ones should be considered pathognomonic, and what is their significance? (3). What can clinicians do for their patients now, in the absence of the kind of data we need to answer either of the other two questions with any degree of certainty? Although it is not possible at this point in time to answer any of these questions definitively, it does seem increasingly clear that the problems are complex, not only at the cellular level, but also (and perhaps more so) at the conceptual level. The common report of “brain fog,” for example, very much needs to be explored, in order to determine what this vague term actually means, and what, if anything, can be done to allevi- ate it. This will require us to rethink such basic concepts as consciousness, and also to commit ourselves to genuinely interdisciplinary study.

Background To evaluate incidence and search for possible predictors of brain fog and quality of life at work (QoL-W) among low-to-moderate risk subjects previously hospitalized due to COVID-19. Material and Methods Participants aged ≥18 retrospectively reported 8 brain fog symptoms pre-COVID-19, at 0–4, 4–12 and >12 weeks post-infection via validated clinical questionnaire. The QoL-W was assessed with a 4-point Likert scale where 0, 1, 2, and 3 meant no, mild, moderate, and severe impairment in performing activities at work, respectively. Data on age, sex, comorbidities, and laboratory results (including first in-hospital high-sensitivity cardiac troponin I [hs-cTnI] measurement) were gathered. Results The study included 181 hospitalized subjects (age Me = 57 years), 37.02% women. Most had low disease severity (Modified Early Warning Score = 1, 77.90%) and low comorbidity (Charlson Comorbidity Index 0: 28.72%, 1–2: 34.09%), with no intensive care unit treatment needed. COVID-19 led to almost 3-fold increased brain fog symptoms, with incidence of 58.56%, 53.59%, and 49.17% within 4, 4–12, and >12 weeks, respectively (p < 0.001). First in-hospital hs-cTnI levels were 47.3% higher in participants who later presented with brain fog at median follow-up of 26.7 weeks since the diagnosis of the SARS-CoV-2 infection. Individuals who experienced at least one brain fog symptom at follow-up, had elevated hs-cTnI, less often presented with atrial fibrillation, and used anticoagulants during initial hospitalization due to COVID-19. The Hs-cTnI >11.90 ng/l predicted brain fog symptoms in multivariable model. COVID-19 was associated with 3.6‑fold, 3.0‑fold, and 2.4-fold QoL-W deterioration within 4, 4–12, and >12 weeks post-infection (p < 0.05). Subjects with QoL-W decline >12 weeks were younger, mostly women, had more brain fog symptoms, and higher platelet counts. Multivariable models with self-reported brain fog symptoms (responding coherently and recalling recent information), age, and sex exhibited good discriminatory power for QoL-W impairment (area under the receiver operating characteristic curve 0.846, 95% CI: 0.780–0.912). Conclusions This study highlighted that in non-high-risk subjects hospitalized during the first 2 pandemic’s waves: 1) brain fog was common, affecting nearly half of individuals, and impacting QoL-W >12 weeks after initial infection, 2) after 3 months of COVID-19 onset, the decline in QoL-W was primarily attributed to brain fog symptoms rather than demographic factors, health conditions, admission status, and laboratory findings, 3) components of brain fog, such as answering in an understandable way or recalling new information increased the likelihood of significantly lower QoL-W up to tenfold, 4) biochemical indicators, such as the first hs-cTnI level, might predict the risk of experiencing brain fog symptoms and indirectly decreased QoL-W >12 weeks after COVID-19 onset. Occupational medicine practitioners should pay particular attention to younger and female subjects after COVID-19 complaining of problems with answering questions in understandable way or recalling new information as they have an increased risk of QoL-W impairment.

Opis:
W pracy analizowano skuteczność metod detekcji mgieł, opartych na danych z satelity MSG 2. Porównano metody teledetekcyjne z obserwacjami stanu pogody na stacjach synoptycznych IMGW-PIB z obszaru Polski, obejmującymi okres od października 2010 r. do marca 2011 r. Stwierdzono, że dane satelitarne pozwalają z dużym prawdopodobieństwem wskazać obszary występowania mgieł i niskich chmur Stratus. Określenie, kiedy występuje mgła, a kiedy tylko niski Stratus jest jednak bardzo trudne, a często niemożliwe, bez wykorzystania dodatkowych danych naziemnych. W tym celu można wykorzystać temperaturę punktu rosy i temperaturę powietrza mierzoną w klatce meteorologicznej. Rozróżnienie mgieł i chmur niskich jest bardzo cenne ze względów praktycznych, ponieważ mgła powoduje ograniczenie widzialności poniżej 1 km, natomiast chmura Stratus nie musi znacząco wpływać na możliwość obserwacji obiektów przy powierzchni ziemi. Metoda omówiona w pracy pozwoliła na wykrycie 50-64% zaobserwowanych mgieł. Około 25-35% sygnalizowanych przypadków wystąpienia mgły nie znalazło potwierdzenia w obserwacjach ze stacji synoptycznych (wystąpił tzw. fałszywy alarm).
The study analyzed the effectiveness of mists detection methods, based on MSG satellite data. Remote sensing methods were compared with observations from synoptic stations IMGW-PIB from Poland, covering the period from October 2010 to March 2011. Satellite data allow identify areas likely occurrence of fog and low stratus clouds. Term when there is fog and low stratus soon but it is very difficult, if not impossible, without the use of additional ground-based data. For this purpose, can be use the dew point temperature and air temperature measured in meteorological cage. The distinction between fog and low clouds is very important for practical reasons, because fog reduces visibility less than 1 km, while the Stratus cloud doesn't have a significant impact on the ability to observe objects close to the ground. The method discussed in the paper made it possible to detect 5064% of observed fog. Approximately 25-35% of cases of fog signaled not confirmed in observations from synoptic stations (it was false alarm).

Opis:
Jakość powietrza w Polskich miastach jest w złym stanie. Alarmujący stan środowiska naturalnego jest w dużej mierze efektem zaniechań i błędów popełnionych w przeszłości, nawet tej bardzo odległej. Ostatnie lata pokazują, jak zmienił się klimat i jak negatywnie te zmiany wpływają na zdrowie ludzi. Z powodu smogu w Polsce rokrocznie umiera więcej osób niż w wyniku wypadków na drogach. Artykuł powstał jako próba odpowiedzi na pytania: jak przedstawia się poziom zanieczyszczeń powietrza w polskich miastach oraz jakie działania podejmują władze na poziomie lokalnym i centralnym, aby zmniejszyć przyczyny i skutki tych zanieczyszczeń.
Air quality in Polish cities is in poor condition. The alarming condition of the natural environment is largely the result of omissions and past mistakes, even the distant ones. Recent years show how the climate has changed and how negatively these changes affect people’s health. Every year more people die from smog in Poland than as a result of road accidents. The article was created as an attempt to answer the questions: what is the level of air pollution in Polish cities and what actions are taken by the authorities at the local and central level to reduce the causes and effects of these pollutants.

Opis:
Diabetes stands as the most widely recognized acute disease globally, resulting in death when it is not treated in an appropriate manner and time. We have developed a closedloop control system that uses continuous glucose, carbohydrate, and physiological variable data to regulate glucose levels and treat hyperglycemia and hypoglycemia, as well as a hypoglycemia early warning module. Overall, the proposed models are effective at predicting a normal glycemic range from >70 to 180 mg/dl, hypoglycemic values of <70 mg/dl, and hyperglycemic value of 180 mg/dl blood sugar levels. We undertook a seven-day, day-and-night home study with 15 adults. Initially, we started with checking insulin levels after meal consumption, and later, we concentrated on how our system reacted to the physical activity of the patients. Evaluation was conducted based on performance parameters such as precision (0.87), recall (0.87), F-score (0.82), delay (26.5±3), and error size (1.14±2).
