The burden of viral lower respiratory tract infections during the neonatal period: sixyear experience at a tertiary referral hospital

Aim To identify the epidemiological and clinical features of acute viral lower respiratory tract infections (LRTI) caused by respiratory syncytial virus and other respiratory viruses, and to determine the risk factors for the severe disease among neonates. Methods We retrospectively reviewed the records of neonates aged up to 44 postconceptional weeks who were hospitalized at a tertiary referral hospital due to confirmed viral LRTI between January 2015 and December 2020. Results Of 228 neonates with viral LRTI, one-third were born prematurely. A seasonal distribution of LRTIs from December to March was noticed, peaking in February. Forty-two percent of neonates were treated in the neonatal intensive care unit. One third of these presented with complications and needed mechanical ventilation. The most detected viruses were respiratory syncytial virus and rhinovirus. Prematurity was identified as a risk factor for worse clinical course and more complications, while rhinovirus infection was associated with an increased risk of apnea. Conclusions The burden of respiratory syncytial virus LRTI in the neonatal period is high, although other respiratory viruses can also cause a severe respiratory disease. In preterm infants, rhinovirus infection presents an important risk factor for a severe course of LRTI with complications. Infection with two respiratory viruses leads to a more severe clinical cours

On Designing a Machine Learning Based Wireless Link Quality Classifier

Ensuring a reliable communication in wireless networks strictly depends on the effective estimation of the link quality, which is particularly challenging when propagation environment for radio signals significantly varies. In such environments, intelligent algorithms that can provide robust, resilient and adaptive links are being investigated to complement traditional algorithms in maintaining a reliable communication. In this respect, the data-driven link quality estimation (LQE) using machine learning (ML) algorithms is one of the most promising approaches. In this paper, we provide a quantitative evaluation of design decisions taken at each step involved in developing a ML based wireless LQE on a selected, publicly available dataset. Our study shows that, re-sampling to achieve training class balance and feature engineering have a larger impact on the final performance of the LQE than the selection of the ML method on the selected data.Comment: accepted in PIMRC 2020. arXiv admin note: text overlap with arXiv:1812.0885

Towards Sustainable Deep Learning for Multi-Label Classification on NILM

Non-intrusive load monitoring (NILM) is the process of obtaining appliance-level data from a single metering point, measuring total electricity consumption of a household or a business. Appliance-level data can be directly used for demand response applications and energy management systems as well as for awareness raising and motivation for improvements in energy efficiency and reduction in the carbon footprint. Recently, classical machine learning and deep learning (DL) techniques became very popular and proved as highly effective for NILM classification, but with the growing complexity these methods are faced with significant computational and energy demands during both their training and operation. In this paper, we introduce a novel DL model aimed at enhanced multi-label classification of NILM with improved computation and energy efficiency. We also propose a testing methodology for comparison of different models using data synthesized from the measurement datasets so as to better represent real-world scenarios. Compared to the state-of-the-art, the proposed model has its carbon footprint reduced by more than 23% while providing on average approximately 8 percentage points in performance improvement when testing on data derived from REFIT and UK-DALE datasets

Arrhythmogenic Cardiomyopathy

Arrhythmogenic cardiomyopathy (AC) is a genetic disease of the myocardium characterized by fibro-fatty replacement of the apoptotic myocardium. It primarily affects the right ventricle, however in advanced stages of the disease the left ventricle can also be significantly affected. AC is a challenging diagnosis, especially in the early stages of the disease, and should be considered in all patients presenting with palpitations, syncope or sudden cardiac death when other, more common causes of these symptoms/signs are excluded. In patients with suspected AC, evaluation according to the current Task Force Criteria should be applied to achieve optimal diagnostic yield. The main therapeutic concern in AC patients is the prevention of SCD, and thus all patients with established diagnosis have to be evaluated for potential ICD implantation, which is indicated in the majority of symptomatic patients. In this narrative review we aim to outline current knowledge on the pathophysiology, diagnosis and treatment strategies of AC

Razlika v ukrepanju policije pri zajetju talcev in amok situacijah : diplomsko delo visokošolskega strokovnega študija Varstvoslovje

Ukrepanje policistov v kriznih situacijah zahteva dobro poznavanje teorije in prakse reševanja pojava, s katerim se soočajo. Poleg »klasičnih« kriznih situacij (zajetje in ugrabitev talcev ter zabarikadiranja v objekte) tuje policije v zadnjih desetletjih obravnavajo specifično krizno situacijo, t. i. amok situacijo. Pojav sicer ni posledica sodobnega načina življenja, saj je antropološko opisan že v 19. stoletju. Od »klasičnih« situacij se razlikuje tako v načinu storitve kot v pristopu k reševanju, ki ga praviloma izvajajo za to usposobljene enote policije (pogajalske skupine, specialna enota). Intervencija je pri amoku skoncentrirana na ukrepanje policistov, ki so prvi poslani na kraj dogajanja. Storilec v nekontroliranem besu pobija naključne žrtve, zato sta vsako odlašanje z intervencijo s strani policistov ter čakanje na ostale enote usodni za žrtve v situaciji. Z analizo situacij amok in zajetja talcev smo iskali razlike med psihološkimi profili storilcev teh dejanj, v načinu delovanja in taktike ter tehnike reševanja policijskih enot. Obravnava odmevnih primerov kriznih situacij v svetu je pokazala, da so tuje policije večinoma zelo dobro usposobljene za reševanje kriznih situacij. Slovenska policija v primerjavi s situacijo zajetja talcev praktično ne razpolaga z nobenim strokovnim gradivom, ki bi ga lahko uporabili pri teoretičnem in praktičnem usposabljanju policistov za primer situacije amok. Vse je še v povojih. Slovenska zakonodaja je glede uporabe orožja v policiji podobna državam v Evropi, kjer je že prišlo do amok situacije. Iz tega izhaja, da je slovenski prostor potencialno okolje, v katerem lahko pride do amok situacije.Police action in crisis situations requires a good knowledge of theory and practice on how to solve the phenomenon they are facing. In addition to "classic" crisis (hostage-taking and barricading in buildings) in recent decades, foreign police also treat specific crisis situations named amok situations. The appearance of amok situations are not a consequence of the modern lifestyle, it has been anthropologically described in the 19th century already. Amok situations differs from “classic” situations in the service as well as in the approach of solving, and usualy is carried out by specially trained police units (Negotiating Group, Special Forces). In an amok situation, the intervention is concentrated on the action of the first police officers sent to the scene. The perpetrator kills random victims in uncontrolled rage, so any delay of intervention by the policemen and any delays resulting from waiting for the other units can be fatal mistakes for victims in the situation. By analyzing amok situations and the hostage-taking situation, we were looking for differences between the psychological profiles of perpetrators of such acts, differences in the mode of action and tactics, and also differences in techniques police units use to solve situations. Treatment of high-profile cases (wide response cases) of crisis situations from other parts of the world has shown that foreign police are very well trained to deal with these events. In comparison, Slovenian police practically do not have any professional materials that could be used by policemen in a theoretical way, nor do they have practical training for such amok situations. Slovenian legislation regarding the use of weapons for police use is similar to legislations in other countries of Europe, where amok situations already have occurred. Hence it follows that Slovenia is a potential environment where amok situations can happen as well

Computer software for business and specific purposes in wood industry

V 211 slovenskih mikro in majhnih lesnih podjetjih, katerih osnovna dejavnost (po SKD) zajema proizvodnjo pohištva za poslovne prostore, proizvodnjo kuhinjskega pohištva in proizvodnjo drugega pohištva, smo preučili razširjenost ter uporabo poslovnih in namenskih računalniških programov. Raziskava je temeljila na primerjalni analizi in oceni stanja programske opreme. Oceno stanja smo izvedli s pomočjo ankete, ki smo jo distribuirali prek različnih medijev. Odziv na anketo je bil v povprečju 23,7 %. Ocenimo lahko, da so računalniški programi v mikro in majhnih lesnih podjetjih na nekaterih področjih intenzivneje uporabljani kot na drugih. Ugotovili smo, da podjetja v večini uporabljajo pri poslovanju pisarniške programe, predvsem tiste podjetja Microsoft. Uporaba specializirane programske opreme je še precej omejena, saj jo pri poslovanju uporablja le 40 % preučevanih podjetij. Nekoliko bolj uporabljajo programsko opremo namenjeno konstruiranju (60 %).The range and usage of computer software for business and specific purposes were researched in 211 micro and minor wood firms, encompasing the production of office furniture, kitchen furniture and some other furniture as the basic activity, according to Statistical Classification Activities (SCA). The research was based on comparative analysis and software condition evaluation. Evaluation of the current situation was carried out by means of a questionnaire, distributed with the help of media. The response was as high as 23.7 %. It can be estimated that the computer software in these micro and minor wood firms is used more often in some areas than in others. It was found out that the firms use mainly office software- especially Microsoft ones. The usage of specialized software equipment is still quite limited in these firms. Only 40 % of the tested firms use is software for their business, meanwhile the equipment designed for construction is more frequently used (60 %)

Measurement automation in beehives using IoT technologies

Živimo v casu, ko je elektrotehnika vseprisotna. V navezi z agrokulturo se je razvila t. i. precizna agrokultura. Ena izmed nadaljnjih delitev je precizno cebelarstvo. Ukvarja se z neinvazivnim zbiranjem podatkov o cebelji družini v želji optimirati cebelarjenje in povecati pridelek. Cilj te magistrske naloge je prispevati ravno na tem podrocju. V uvodnem delu smo umestili cebelo v živalsko kraljestvo. Naredili smo pregled komercialnih rešitev na podrocju preciznega cebelarstva. Ugotovili smo, da gre po vecini za elektronske tehtnice. Na raziskovalnem podrocju smo zasledili clanke, ki na podlagi akusticnih znacilk išcejo nacin prepoznavanja aktivnosti cebel. Akademski projekt E-Ruche se osredotoca na zbiranje podatkov o temperaturi znotraj panja na desetih merilnih mestih. Pri nekoliko mlajšem projektu imenovanem ITAPIC so realizirali brezžicno komunikacijo senzorjev z vozlišcem. Naslednje poglavje predstavi bistvene tehnologije in têrmine uporabljene pri tej magistrski nalogi. Med njimi so: upogibne meriline celice (uporovni listici), protokol I2C, pojem IoT, oblikovanje podatkov JSON, princip REST, programski jezik JavaScript, nerelacijska podatkovna baza MongoDB in Google Material. V osrednji temi smo najprej opisali izdelavo štiritockovne elektronske tehtnice. Izdelali smo jo z upogibnimi merilnimi celicami. Pri izdelavi smo naleteli na nekaj težav zaradi premajhne izhodne napetosti in omejitve napajanja. Meritve smo morali na koncu izvajati samo z eno merilno celico. Temperaturo in vlago zunaj in znotraj panja smo merili s senzorjema DHT22. Senzorsko vozlišce je preko protokola I2C zajemalo meritve s senzorjev v rednih intervalih in jih posredovalo spletnemu strežniku. Pri poglavju o spletni aplikaciji smo opisali nacrtovanje podatkovnih struktur uporabnika in optimizacijo hrambe odcitkov senzorjev. Aplikacija vsebuje spletni vmesnik, ki je oblikovno narejen po vzoru Google Material. Omogoca identifikacijo uporabnika, prikaz senzorjev in ponazoritev preteklih meritev z grafom. V zadnjem poglavju smo opisali testno postavitev sistema, postavljena v zacetku avgusta. Tehtnico smo podložili pod cebelji panj, senzorja temperature in vlage smo namestili v za to prirejeno satnico in ohišje zunaj panja. Meritve smo zbirali približno štiri dni. Kolicina podatkov je bila premajhna za resno analizo, vendar smo lahko vseeno opazovali nekaj kratkotrajnih pojavov in njihovih vplivov na meritve.We live in a time where electronic devices are present on every step. In relation with agriculture the so-called precision agriculture has developed. One of the further division of it is precision beekeeping. It deals with the non-invasive data collection about bee colonies in a wish to optimize resource usage and increase honey production. The aim of this master thesis is to contribute precisely to this area. In the introductory section we placed the bees within the animal kingdom. We made a review of the commercial solutions in the field of precision beekeeping. We have found that the majority were electronic scales. In the research field we identified articles which on the basis of acoustic features look for a way of identifying the activities of the bees. The academic project E-Ruche focuses on collecting data about temperature inside the hive up to ten measuring points. In a somewhat earlier project called ITAPIC, communication was realized through wireless communication sensors with the sensor node. The following chapter presents the basic technologies and the terms used in this master thesis. Among them are: load cell (strain gauge), protocol I2C, the concept of IoT, data formatting JSON, REST principle, JavaScript, nonrelational database MongoDB and Google Material. Within our central topic, we first describe the production of fourpoint electronic scales. We developed it with load cell technology. In the manufacturing, we encountered some problems due to low output voltage and charging limitations. At the end the measurements were carried with only one load cell. The temperature and humidity inside and outside the hive was measured by sensors DHT22. The sensor with the use of the protocol I2C covered measurements at regular intervals and submitted them to the web server. In the chapter regarding the web application, we described the programming of user data structures and the optimization of the sensor data retention. The application contains a web interface, which is modeled after Google Material. It allows the identification of the user, a display of sensors and illustrates recent measurements using a graph. In the last chapter, we described a test system built in the beginning of August. The scale was padded under the hive, we placed the temperature and moisture sensor in a special modified honeycomb and housed it outside the hive. Measurements were collected for approximately four days. The amount of data was too small for serious analysis, but we could still observe some short-term phenomena and their impact on the measurements
