Političari Evropske unije su zdravstvenu njegu identifikovali kao uređenu profesiju koja ima uticaj na sigurnost i javno zdravlje stanovništva uz posjedovanje karakteristika općeg javnog interesa. Zakonskom legislativom u FBiH je uređena djelatnost medicinskih sestara -tehničara, primalja, način obavljanja i organiziranja djelatnosti, standard obrazovanja i uslovi za obavljanje djelatnosti medicinskih sestara i primalja, prava, obaveze i odgovornosti medicinskih sestara i primalja, te kontrola sigurnosti i kvalitete rada. Profesionalno pravno tijelo sa jasnim ovlaštenjima, koje okuplja i zastupa medicinske sestre-tehničare različitih nivoa obrazovanja je Komora medicinskih sestara-tehničara. Pored brojnih zadataka koje Komora provodi je zagovaranje i implementacija strategija i politika od posebnog interesa za unaprijeđenje profesionalnog i stručnog razvoja. To obuhvata područje standardizacije prakse i proširenje kompetencija u skladu sa stečenim kvalifikacijama. Za ostvarenje cjelokupnih profesionalnih ciljeva neophodna je intersektorska saradnja Komore sa ustanovama koje obrazuju i upošljavaju profesionalce za zdravstvenu njegu. Koordiniranom i kontinuiranom saradnjom moguće je uskladiti zajedničke interese i ostvariti očekivanja profesionalaca u različitim nivoima prakse. Cilj je da stečene kompetencije u okviru visokoškolskog obrazovanja moraju postati operativne u radnim organizacijama. U tom procesu Komora može i mora uložiti sve napore da pomogne zdravstvenim i drugim srodnim organizacijama da razumiju i implementiraju savremene modele zdravstvene njege, te iskoriste ljudske potencijale koji se stavljaju na raspolaganje zdravstvenom tržištu u našoj zemlji. Snaga profesionalne komore je u definisanju, distinkciji, proširenju kompetencija u zdravstvenoj njezi i standardizaciji prakse, te može da bude polazna osnova za reformske procese u zdravstvenom sistemu. U radu će biti prikazani prednosti i nedostatci u procesu koordinirane saradnje profesionalnih sestrinskih tijela, obrazovnih i zdravstvenih ustanova u zemlji.

Uvod: Jednofotonska emisiona tomografija (SPECT) značajno je unaprijedila nuklearno-medicinsku dijagnostiku. Nedostatak SPECT metode su relativno niski signal-šum odnos (SNR) kao i kontrast-šum odnos (CNR). Nizak broj fotona slike predstavlja veliki problem kod SPECT snimanja zbog smanjenja signala uz povećanje šuma (pozadine slike). Zadnjih godina veliki broj naučnika ističe značaj SPECT snimanja niskog broja signala korištenjem savremenih detektorskih sistema i naprednih softverskih modaliteta. Najznačajniji napredak rekonstrukcije SPECT snimaka predstavlja primjena metode oporavka rezolucije (RR) kod snimanja miokarda (Myovation Evolution) i koštanog sistema (Evolution for Bone) jer dugotrajna SPECT akvizicija smanjuje komfor uz pojavu artefakata micanja i smanjenje kvaliteta slike. Savremeni metod zasnovan je na principu “Half-Time SPECT” uz jednaku senzitivnost i specifičnost tomografske studije. Materijal i metode: Istraživanje je provedeno kao prospektivna klinička eksperimentalna studija na uzorku od 100 pacijenata sa potvrđenom onkološkom dijagnozom. Izvršena je komparacija snimaka pune i skraćene dužine akvizicije (skraćenje za 25 i 50% od pune akvizicije). Svi snimci su rekonstruisani sa tri različita protokola. Ukupno je ispitano 9 različitih SPECT protokola. Na svim snimcima nivo šuma, odnos signal-šum kao i odnos kontrast-šum su mjereni za isto anatomsko područje. Rezultati: Skraćenjem trajanja akvizicije zabilježen je porast vrijednosti šuma, najblaži porast zabilježen je korištenjem Evolution for Bone protokola. Smanjenjem trajanja akvizicije SNR i CNR značajno su smanjeni, dok je protokol koji je koristio RR modalitet zabilježio veću vrijednost SNR i CNR na 50% akvizicije u odnosu na punu akviziciju bez RR modaliteta. Zaključci: Analizom snimaka skraćene i pune akvizicije uz primjenu parametara rekonstrukcije došlo se do zaključka da RR modalitet omogućava skraćenje trajanja SPECT akvizicije bez značajnog uticaja na povećanje vrijednosti šuma. SNR i CNR primjenom RR modaliteta i dalje mogu ostati visoki pri čemu je omogućena jasna detekcija patoloških lezija kao i kod pune SPECT akvizicije.

The paper deals with the phenomenon of non-fungible tokens (NFT), and its particular focus is on the so-called “Art NFTs”, and on the legal demystification of the superior attributes assigned to these tokens. The paper addresses a number of issues. Firstly, it examines the legal and technical possibility to actually create a “digitally unique” piece of author’s work. Secondly, it explores the acquisition of ownership and copyright in the work of art, to which the NFT referres to, during the process of creation and transfer of that NFT. Finally, the paper scrutinizes the topics of copyright violations, which may occur while minting the tokens and of the destruction of the physical original of the tokenized work. The paper also deals with two relevant cases from practice (Miramax, LLC v. Tarantino and Free Comb With Pagoda, J.M. Basquiat), which illustrate how the so-called “Art NFTs” collide with copyright principles.

Introduction: As a result of research conducted globally, experts continue to extensively study the long-term consequences that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can have on patients, as well as the factors contributing to severe outcomes. The aim of this study was to investigate the values of basic biochemical and hematological parameters in patients with fatal outcomes of SARS-CoV-2 infection, as well as to determine the combination of hematological and biochemical parameters that contribute to the progression of SARS-CoV-2 infection. The examined parameters were correlated with the age and gender distribution of patients with fatal outcomes from the SARS-CoV-2 infection. Methods: The study represents a retrospective study of patients hospitalized at the Cantonal Hospital Zenica from February to April 2021, focusing on the biochemical and hematological parameters of subjects with confirmed presence of the SARS-CoV-2 virus using the reverse transcription-polymerase chain reaction methods who were hospitalized at the Cantonal Hospital Zenica. Results: Of the 250 deceased subjects in the sample, females comprised the relative majority at 53.6%. Among the examined parameters, hemoglobin, mean corpuscular hemoglobin (MCH), and MCH were significantly lower in females compared to males, while males had significantly higher values of urea, creatinine, and troponin. The average age of the patients was 74 years, and with aging, the values of erythrocytes, hemoglobin, and troponin increased. Troponin showed a statistically significant positive correlation with age, as well as with urea and creatinine. Conclusion: We can conclude that hemoglobin, urea, creatinine, and troponin are parameters that can be considered to contribute to the progression of SARS-CoV-2 infection. These parameters can be useful for assessing disease severity and prognosis in patients infected with the SARS-CoV-2 virus.

To provide seamless wireless coverage, the air-to-ground (A2G) heterogeneous wireless network is considered as one of the most promising solutions. In this article, we develop a novel A2G communication-caching-charging (3C) integrated network based on non-orthogonal multiple access (NOMA). As a significant participant of A2G network, unmanned aerial vehicle (UAV), which harvests energy from the base station (BS) with the aid of wireless power transfer (WPT), is utilized as content server to cache files and serve users. To be specific, we first propose a resource allocation strategy to enhance the quality of service (QoS) of ground users. The goal is to minimize the transmission latency of ground users, which is decomposed into sub-problems, such as user pairing, files' power allocation and users' power allocation. Firstly, we propose a NOMA user pairing algorithm based on K-means to deploy UAVs and pair users. Then, the closed-form solution for files' power allocation with the goal of maximizing the duration for energy harvesting is formulated. Finally, we apply the genetic algorithm (GA) to obtain power allocation factors to increase users' rate and the reminder time of content delivery phase is utilized for energy harvesting. Simulation results validate the advantage of the proposed strategy in reducing user delay than benchmark schemes.

To establish more intelligent cellular networks for future ubiquitous access and heterogeneous devices, we need to obtain channel state information (CSI) in a more agile and economical manner, especially for frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) architectures. Unlike conventional CSI feedback or limited feedback methods, we can predict downlink CSI by leveraging channel reciprocity between uplink and downlink. The downlink CSI prediction can be formulated as a data-driven deep learning task, however, there exist isolated data silos and online adaptation problem for the offline trained neural network-based models. In this article, we propose an interacting federated and transfer learning (IFTL) based framework for downlink CSI prediction and online update, where several factors including asynchrony of different clients are considered, and light heterogeneity of diverse cells can be tolerated. Both model-level and link-level simulations are conducted under standardized FDD massive MIMO scenarios. The results outline promising prospect and potential of the utilization of federated learning and transfer learning in physical layer of wireless communications.

Specific emitter identification (SEI) is a potential physical layer authentication technology, which is one of the most critical complements of upper layer authentication. Radio frequency fingerprint (RFF)-based SEI is to distinguish one emitter from each other by immutable RF characteristics from electronic components. Due to the powerful ability of deep learning (DL) to extract hidden features and perform classification, it can extract highly separative features from massive signal samples, thus enabling SEI. Considering the condition of limited training samples, we propose a novel few-shot SEI (FS-SEI) method based on interpolative metric learning (InterML) which gets rid of the dependence on auxiliary dataset. Specifically, InterML is designed to mine more implicit samples in the sample space to improve generalization, and constrain the feature distance in the feature space to improve discriminability. The proposed InterML-based FS-SEI method is evaluated on a real-world Wi-Fi dataset. The simulation results show that the proposed method achieves better identification performance, higher feature discriminability and more stable performance than five latest FS-SEI methods. In the 10 shot scenario, the identification accuracy of InterML is 91.48%, compared to the comparison methods, the accuracy is improved by 0.62%–31.29%.
