COVID 19 pandemic has led the world authorities, in particular health authorities, to totally reconsider the infectious problems in all public places and in particular in hospitals, that are also burdened by specific risks, due to the concentration of subjects at risk and the consequences that necessary treatments, such as resistance of infectious agents to the drugs used, may involve. Therefore, traditional and innovative methods were compared to obtain adequate protection from contaminants, paying particular attention to the disinfection method by means of ultraviolet rays emitted by a special robotic instrument named R2S Robot. The studies carried out on the subject show that UV-C method represents a rational, effective and economically sustainable choice to ensure adequate disinfection, not only of hospital environments in general but also of frequently visited environments such as public areas and institutions, schools of all types and levels, public and private offices, especially in the light of the new regulations that have totally changed the general approach and the degree of responsibility towards not only the regular visitors of the nosocomial environments, but also the dedicated operators.

The City

In the times of unification of cultural patterns the art in public areas takes on a very responsible role – creating cognitive map and emphasizing identity of the place. Valuable architectural and sculpture monuments take deserved top position in creating unique townscape. But not only spectacular buildings create the image of the city, sometimes inconspicuous sculptures become city symbols. The subject of research conveyed by the author in Poznan was the quality of public areas and possibilities of making them more attractive by introducing monuments and water elements. Autor define the typology of public art objects (considering their function, form and scale) and methodology of lacalization from the city-scale (according to the viewing popularity aspects and rank of the place) to the csale of indyvidual urban interior. The spatial and social role of sculpture in urban area was analized on examples of public places in Poznan. Vizualinio meno lokalizacijos viešosiose erdvėse metodologija poznanės pavyzdžiu Santrauka Vienodėjant kultūriniams kontekstams viešųjų erdvių menas įgyja ypatingą ir labai svarbią reikšmę kaip atpažinimo elementais atskleidžiantis ir pabrėžiantis vietos identitetą. Vertingi architektūriniai ir skulptūriniai elementai tampa svarbiausiais unikalių miestovaizdžių formantais. Tačiau ne tik įspūdingi statiniai kuria miesto vaizdą. Kartais niekuo neišsiskiriančios, vos pastebimos skulptūros tampa miesto simboliais. Tyrimo, atlikto Poznanės mokslininkės, tema yra viešųjų erdvių kokybė ir galimybė padidinti jų patrauklumą meno kūriniais ir vandens elementais. Autorė apibrėžė viešojo meno objektų tipologiją, įvertindama jų paskirtį, formą ir mastelį, ir lokalizacijos metodiką nuo viso miesto masto iki mažiausiojo mastelio nominalių erdvių, įvertindama apžvalgos populiarumą ir vietos kategoriją. Poznanės pavyzdžiu išanalizuotas tiek erdvinis, tiek visuomeninis miesto skulptūrų vaidmuo.

Perimeter control is used to regulate transfer flows between urban regions. The greedy control (GC) method takes either the minimum or the maximum for the control inputs. Although it has the advantage of simplicity for real-time feasibility, a few existing studies have shown that it can sometimes have negative impacts because of unnecessary transfer flow restrictions. To reduce unnecessary restrictions, this study provides a method that gives flexibility to ease the strict conditions of the conventional GC. First, we propose a modification as a way of granting exceptions to the flow restriction under specific conditions. Second, we develop an algorithm to determine the threshold dynamically for accepting the exception, by comparing the possible outflow loss of the subject region and the possible outflow gain of its neighboring regions. The test results show that this flexible greedy control can handle the balance between the transfer demands and the greed of regions for securing the supply level, while increasing the performance in both vehicle hours traveled and trip completion.

Background: Enhanced terminal room cleaning with ultraviolet C (UVC) disinfection has become more commonly used as a strategy to reduce the transmission of important nosocomial pathogens, including Clostridioides difficile, but the real-world effectiveness remains unclear. Objectives: We aimed to assess the association of UVC disinfection during terminal cleaning with the incidence of healthcare-associated C. difficile infection and positive test results for C. difficile within the nationwide Veterans Health Administration (VHA) System. Methods: Using a nationwide survey of VHA system acute-care hospitals, information on UV-C system utilization and date of implementation was obtained. Hospital-level incidence rates of clinically confirmed hospital-onset C. difficile infection (HO-CDI) and positive test results with recent healthcare exposures (both hospital-onset [HO-LabID] and community-onset healthcare-associated [CO-HA-LabID]) at acute-care units between January 2010 and December 2018 were obtained through routine surveillance with bed days of care (BDOC) as the denominator. We analyzed the association of UVC disinfection with incidence rates of HO-CDI, HO-Lab-ID, and CO-HA-LabID using a nonrandomized, stepped-wedge design, using negative binomial regression model with hospital-specific random intercept, the presence or absence of UVC disinfection use for each month, with baseline trend and seasonality as explanatory variables. Results: Among 143 VHA acute-care hospitals, 129 hospitals (90.2%) responded to the survey and were included in the analysis. UVC use was reported from 42 hospitals with various implementation start dates (range, June 2010 through June 2017). We identified 23,021 positive C. difficile test results (HO-Lab ID: 5,014) with 16,213 HO-CDI and 24,083,252 BDOC from the 129 hospitals during the study period. There were declining baseline trends nationwide (mean, −0.6% per month) for HO-CDI. The use of UV-C had no statistically significant association with incidence rates of HO-CDI (incidence rate ratio [IRR], 1.032; 95% CI, 0.963–1.106; P = .65) or incidence rates of healthcare-associated positive C. difficile test results (HO-Lab). Conclusions: In this large quasi-experimental analysis within the VHA System, the enhanced terminal room cleaning with UVC disinfection was not associated with the change in incidence rates of clinically confirmed hospital-onset CDI or positive test results with recent healthcare exposure. Further research is needed to understand reasons for lack of effectiveness, such as understanding barriers to utilization.Funding: NoneDisclosures: None

Much has been written of William Duncan, "the Apostle of Alaska", who came to the coast of northern British Columbia in 1857 as a missionary to the Tsimshian Indians. Although he deplored it, in the course of his sixty years' residence in this area controversy raged around him as a result of his clashes with church and state, and his work has been the subject of numerous investigations, both public and private. His enemies have called him a tyrant and a ruthless exploiter of the Indians under his control; and there are men still living who find a disproportionate amount of evil in the good that he did, especially during the declining years of his long life. On the other hand, he has had ardent and articulate supporters who have written numerous articles and no less than three books in praise of his self-sacrificing ideals and the soundness of his program for civilizing the Indian.

BACKGROUND The coronavirus disease 2019 (COVID-19) is an ongoing global pandemic caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). The prevention and treatment methods for COVID-19 are not yet clear. At present, there are at least 287 preventive vaccines against COVID-19 in the world, of which 5 vaccines are available for emergency use as of June 2021, but none has completed clinical trial. Nevertheless, with the development of vaccines, disease conditions in various countries are gradually controlled. OBJECTIVE The vaccination rate has increased in time, and activities in various countries have gradually recovered. Therefore, the focus of the next stage is confirming and proving that everyone is vaccinated to ensure that those without vaccines will not become a breach in the next wave of diseases. The vaccination or RT-PCR test results are all certified and verified by paper documents issued by hospitals or testing institutions. Meanwhile, falsified documents are a major risk factor in confirming the vaccination status and laboratory test results. Although the Vaccine Passport (VP) may become an important key to future global activities based on the current strategy, the problems of document verification and data use among countries have not yet been resolved. METHODS The blockchain architecture proposed in this research can be applied together by public and private entities and be rapidly expanded. Furthermore, the open ledger of blockchain achieves transparency and data accuracy. On the other hand, smart contracts (SCs) achieve authorization and authentication, while the encryption and decryption mechanisms achieve data protection. In order to make it globally available, the international data standard “Fast Healthcare Interoperability Resource (FHIR)” is adopted into this research. In general, this blockchain architecture can achieve global vaccine passport verification accurately and at a low cost. RESULTS The open nature of the blockchain contributes to establishing transparency and data accuracy. Total three entities are included in this blockchain architecture. All of the authorization are public in the open ledger. The smart certificate enables authorization and authentication, while the encryption and decryption mechanism ensure data protection. This proof of concept demonstrates the design of blockchain architecture which, when adopted, can achieve global vaccine passport verification accurately and at a cost country can afford. An actual vaccine passport case was established and demonstrated in this study. Open blockchain, individually authorized authentication mechanisms, and international standard vaccine passports were adopted. CONCLUSIONS Blockchain architecture is used to build the authentication process of an executable international vaccine passport, with advantages of low cost, high interoperability, effectiveness, security and verifiability.

Violence as a public and private practice is a constant. Furthermore, it belongs in the political axis since political institutions measure, plan, and distribute it, inscribing and administering it according to their productive and programmatic interests.Violence is adaptable and acquires different forms and formats, which range from the most concrete corporeal reality to the infliction of punishment on the symbolic and emotional registers of the subject. It is mobile but enduring, adjusting to the emergence of new social subjects. The enduring struggle against violence resituates and changes it, bringing about the penalization of practices considered abusive, such as long workdays, certain school regulations, or the beating of women.

The standardised testing of school children has been the subject of significant news media attention in recent years in many developed countries around the world. This article examines the reporting of annual National Assessment Program Literacy and Numeracy (NAPLAN) tests in three major Australian newspapers, with a particular focus on the portrayal of school teachers in the coverage. Overall, teachers were presented as strongly opposed to NAPLAN and the publication of test results, yet the newspapers themselves supported the tests as an important accountability measure. Teachers were depicted as trying to influence the testing system through teaching to the test and cheating. They were presented as generally inadequate as teachers, and were blamed for perceived failings in the educational system. These findings point to implications for teacher recruitment and retention, and for journalism education and training.
