A health technology assessment (HTA) is commonly defined as a multidisciplinary approach used to evaluate medical, social, economic, and ethical issues related to the use of a health technology in a systematic, transparent, unbiased, robust manner. To help inform HTA recommendations, the surveillance of social media platforms can provide important insights to the clinical community and to decision makers on the effectiveness and safety of the use of health technologies on a patient. A scoping review of the published literature was performed to gain some insight on the accuracy and automation of sentiment analysis (SA) used to assess public opinion on the use of health technologies. A literature search of major databases was conducted. The main search concepts were SA, social media, and patient perspective. Among the 1,776 unique citations identified, 12 studies that described the use of SA methods to evaluate public opinion on or experiences with the use of health technologies as posted on social media platforms were included. The SA methods used were either lexicon- or machine learning-based. Two studies focused on medical devices, three examined HPV vaccination, and the remaining studies targeted drug therapies. Due to the limitations and inherent differences among SA tools, the outcomes of these applications should be considered exploratory. The results of our study can initiate discussions on how the automation of algorithms to interpret public opinion of health technologies should be further developed to optimize the use of data available on social media.

Na prostoru Bosne i Hercegovine čuva se izvjestan broj predmeta koji se mogu determinirati kao kopče. Navedeni predmeti služili su u praktične svrhe, ali i kao dio dekorativnoga sadržaja. S obzirom na širok spektar predmeta koji su obrađeni, i datacijski okvir je razmjerno širi i kreće se od 1. stoljeća pa do perioda kasne antike i ranoga srednjeg vijeka.

In the first part of the paper, the continuity equation in the boundary layer for stationary two-dimensional flow is derived on the basis of the law of mass conservation. After that, using Newton's second law for control volume, the equation for the momentum was derived. Using the derived equations, the analysis was performed with respect to the influence of temperature. After that, on the basis of the energy balance, an energy equation was derived in which a viscous dissipation function was introduced, which enabled a wider application. At the end of the paper, the derived equations were applied to a specific calculation example from technical practice in the calculation of thermal quantities in a rectilinear sliding bearing, which was the aim of the work

Bosna i Hercegovina prihvata načelno globalna opredjeljenja i proklamovane ciljeve relevantnih međunarodnih institucija (Pariški Sporazum, Evropski Zeleni Plan, i drugi) za prelaz na održivi niskougljenični razvoj baziran na kružnoj ekonomiji neuslovljenoj upotrebom prirodnih resursa, te težnju ka nultoj neto emisiji stakleničkih gasova. U energetskom sektoru to podrazumijeva povećanje energijske efikasnosti, te bezuvjetni prelaz na obnovljive izvore energije i eliminaciju fosilnih goriva. I dok je opšte opredjeljenje nesporno, način i dinamika ostvarenja pojedinih ciljeva u zacrtanom roku do 2050. godine sa najmanje negativnih ekonomskih, socijalnih, sigurnosnih i političkih posljedica predstavlja ozbiljni izazov, posebno u zemljama koje se, kao Bosna i Hercegovina, tradicionalno oslanjaju na sopstveni ugalj kao primarni energent. U cilju doprinosa iznalaženju optimalnih rješenja u energetskoj transformaciji, a u okviru Plana rada za 2019 godinu, Odbor za energiju, energetiku i okoliš (OEEO) Akademije nauka i umjetnosti Bosne i Hercegovine (ANUBiH) u saradnji i uz finansijsku podršku JP Elektroprivreda Bosne i Hercegovine d.d. Sarajevo, je organizovao regionalnno naučno-stručno savjetovanje: Budućnost postojećih i novih termoelektrana u BiH u energetskoj tranziciji, koje je održano 21. 11. 2019. godine u ANUBiH u Sarajevu. Cilj Savjetovanja je bio da nauka i struka, pod pokroviteljstvom i u okviru ANUBiH, u saradnji sa stručnjacima iz EU i Regije razmjene iskustva, stavove i planove o upotrebi uglja i biogoriva u proizvodnji električne i toplinske energije u periodu do 2050. godine. Na Savjetovanju, kojem su prisustvovali predstavnici vlasti i zvaničnih institucija iz BiH, naučni radnici, stručnjaci, menadžmenti elektroprivrednih organizacija iz oba bh. entiteta, je na bosanskom, srpskom, hrvatskom ili engleskom jeziku na prethodno odabrane teme izloženo 15 referata po pozivu. Pored stručnjaka iz BiH, referate su podnijeli i pozvani eksperti iz zemalja EU i okruženja sa elektroprivrednom strukturom i izazovima u toj oblasti sličnim kao što ih ima i BiH, a koje u proizvodnji električne energije karakteriše značajni, ili čak dominantni oslonac na fosilna goriva, naročito ugalj. U referatima su izloženi mogući modeli tranzicije i iskustva iz BiH, Srbije, Grčke, Sjeverne Makedonije, Poljske i Njemačke. Prošireni sažeci i slide prezentacije svih referata na jezicima na kojima su referati izloženi, kao i Zaključci Savjetovanja su sadržani u ovom Posebnom izdanju ANUBiH. Savjetovanje je potvrdilo da je dekarbonizacija elektroenergetskog sektora u EU i Regiji do 2050. godine opravdan, ali i veoma zahtjevan cilj. Svaka država koja se obavezala za takav cilj, mora razviti svoj model održive tranzicije, koristeći vlastito znanje, pomoć eksperata EU, te iskustva i modele drugih. U tom smislu zaključeno je da je veoma važno u što je moguće kraćem roku, u saradnji sa Energetskom zajednicom, detaljno i odgovorno koncipirati razvoj energetskog sektora u Bosni i Hercegovini u tranzicijskom periodu, dajući pritom do znanja Evropskoj uniji, ali i svima drugima, da je Bosna i Hercegovina spremna pratiti i ispoštovati generalno postavljene ciljeve u toj oblasti, uvažavajući pri tom svoju potrebu za energetskom neovisnošću. U tom cilju potrebno je definirati jasnu viziju, sa prohodnim putem do postavljenih ciljeva, uzimajući u obzir sve relevantne direktive i regulativu EU, ali i realne mogućnosti i potrebe Bosne i Hercegovine. Iskustva i poruke izložene u referatima, diskusije tokom Savjetovanja, te saznanja do kojih smo došli, a koji su sumirani u Zaključcima ovog dokumenta, čine korisnu bazu i orijentir za konkretizaciju strategije za aktuelnu tranziciju energetskog sektora BiH.

Introduction/Objective: A lung abscess is a localized purulent inflammation of lung tissue with necrosis and colliquation. We are presenting a rare case of lung abscess formation as a result of the COVID-19 viral infection. Case report: An 81-year-old male patient with typical complaints (fever, malaise, fatigue) was examined at a designated medical centre for COVID patients. A positive PCR test and radiology findings confirmed a COVID-19 infection. Medication was prescribed according to protocol and he was sent home. During the night, 36 hours after the onset of the first symptoms, the patient developed breathing difficulties and a persistent, irritating dry cough. He was admitted to the Covid Hospital Karaburma, where he received treatment for 35 days. On the 22nd day after being released, the patient was examined at the Emergency Medical Centre, Clinical Centre of Serbia, complaining of dyspnoea, occasional hemoptysis and fatigue. The working diagnosis was pulmonary embolism. A multislice CT scan was ordered only to reveal a pulmonary abscess at the base of the left lung. Conclusion: A lung abscess is a rare, but possible complication of a COVID-19 infection. Therefore, patients should be regularly monitored for an extended period of time following hospitalization.

The family is the basic cell of every society; in it the life of an individual rises, develops and disappears. Family relations are the basis of every social and state system. As a result, all state systems have been trying to keep family relations in peace for centuries. The death of a family member is one of the many factors that can disrupt family harmony, especially under the additional influence of property rights. Centuries ago, the issue of the testator's property was regulated by customary law, and then by legislation. The paper deals with the institute of bequest, as one of the forms of inheritance, with special reference to the types of bequests in the Republic of Serbia. For centuries, bequest has been the institutional of transferring the property and legal relations of the testator to the heirs. The will as we know it today in its form has its basis in Roman law, which had a great influence on the first European civil codes, the Civil Code and the Austrian Civil Code. These codes are still in use today, and their special significance is that they are a panda to all later adopted civil codes, ie to all later established civil legal bases. The Austrian Civil Code had a dominant influence on the settings of the regulation of civil law in the Republic of Serbia. Today, there are nine types of bequests. Each of them follows the life situations, circumstances and circumstances in which it arises.

Inheritance law is a set of legal norms that regulate the property and legal relations of the testator after his death. The fact of death has haunted all social communities for centuries. The loss of a family member affected community members (family) both emotionally and property-wise. After the death of the testator, his property and legal assets remain, the significance of which is reflected on the heirs as well as on third parties, but also on the state as a successor in case of absence of the heirs. The paper deals with the legal regulation of two legal institutes: the contract on lifetime support and the contract on assignment and distribution for life. The paper follows their legislation with reference to certain issues of practice, legal and ethical dilemmas, and in the very conclusion, in parallel with the legal analysis of these two institutes, which by all their characteristics are characterized as legal obligations. These two contracts are the rights of business that have been present in social systems for centuries, their existence and significance have been minimized, and only in modern times have their legal regulations been obtained. Guided by the fact that they are "new" legal institutes, as well as by the fact that the practice, especially during the 90s of the last century, indicated and showed that these first two institutes are suitable for abuse of legislation, the paper addressed the issues of who and when can be a contracting party. , what are the prejudices of the contract, as well as the circumstances when and why they can be null and void, disputed in court or terminated. Man was born manipulative and easy, and the law, and the law, the state and the entire legal system are there to channel it and sanction bad motives, in order to realize an orderly democratic social system, and thus preserve the family as the basic cell of society.

Violence against children is a dynamic, changing social phenomenon. Every society, regardless of the level of development of democracy, economic and political development, regardless of the level of protection of human rights, encounters violence against children on a daily basis. The first professional interests in violence against children were made between the two world wars, but the first active measures to oppose it appeared in the mid-sixties of the twentieth century, in the most developed countries. In the 21st century, the countries of the "third world" remain in a civilizational, cultural, value cocoon. No matter how impossible and imaginary it may seem, in some countries, violence against children is still denied as a social phenomenon and a deviation. The negation of violence does not stem from the circumstance that the child is not physically and mentally punished, but that this "punishment" is justified for the purpose of good upbringing, tradition and similar found excuses. For many years, this attitude has been held in many post-communist states, states that have been isolated for decades, either because of politics or because of religion. However, with the globalization of society, the inevitable opening of borders, but also under great assets whose affirmation of ordinary organizations, primarily at the global and then at the state level, the topic of "violence against children" slowly gained its epilogue. Today, in 2021, violence against children is an open topic in most communities. There are no more taboos. And no turning heads from violence. Of course, there are exceptions, but the world is full of rules with some exceptions. The paper deals with two aspects: global and national, specifically the Republic of Serbia. The paper deals with the definition of the concept of the child, types of violence, legal acts regulating the rights of the child, applied measures, but also proposals for measures and moves to take exceptions (those who deny the existence of violence against children, those who it doesn't matter…) be if not zeroed, and at least minimized.
