Research paper thumbnail of The Impact of COVID-19 Management Policies Tailored to Airborne SARS-CoV-2 Transmission: Policy Analysis

JMIR Public Health Surveillance, 2021

Daily new COVID-19 cases from January to April 2020 demonstrate varying patterns of SARS-CoV-2 transmission across different geographical regions. Constant infection rates were observed in some countries, whereas China and South Korea had a very low number of daily new cases. In fact, China and South Korea successfully and quickly flattened their COVID-19 curve. To understand why this was the case, this paper investigated possible aerosol-forming patterns in the atmosphere and their relationship to the policy measures adopted by select countries.

Objective:
The main research objective was to compare the outcomes of policies adopted by countries between January and April 2020. Policies included physical distancing measures that in some cases were associated with mask use and city disinfection. We investigated whether the type of social distancing framework adopted by some countries (ie, without mask use and city disinfection) led to the continual dissemination of SARS-CoV-2 (daily new cases) in the community during the study period.

Methods:
We examined the policies used as a preventive framework for virus community transmission in some countries and compared them to the policies adopted by China and South Korea. Countries that used a policy of social distancing by 1-2 m were divided into two groups. The first group consisted of countries that implemented social distancing (1-2 m) only, and the second comprised China and South Korea, which implemented distancing with additional transmission/isolation measures using masks and city disinfection. Global daily case maps from Johns Hopkins University were used to provide time-series data for the analysis.

Results:
The results showed that virus transmission was reduced due to policies affecting SARS-CoV-2 propagation over time. Remarkably, China and South Korea obtained substantially better results than other countries at the beginning of the epidemic due to their adoption of social distancing (1-2 m) with the additional use of masks and sanitization (city disinfection). These measures proved to be effective due to the atmosphere carrier potential of SARS-CoV-2 transmission.

Conclusions:
Our findings confirm that social distancing by 1-2 m with mask use and city disinfection yields positive outcomes. These strategies should be incorporated into prevention and control policies and be adopted both globally and by individuals as a method to fight the COVID-19 pandemic.

Methods: The research modeled severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) spreading and dissemination patterns sensitivity by redesigning time series data extraction of daily new cases in terms of deviation consistency concerning variables that sustain COVID-19 transmission. The approach opened a new scenario where seasonality forcing behavior was introduced to understand SARS-COV-2 non-linear dynamics due to heterogeneity and confounding epidemics scenarios. Results: The main research results are the elucidation of three birth- and death-forced seasonality persistence phases that can explain COVID-19 skew patterns worldwide. They are presented in the following order: (1) the environmental variables (Earth seasons and atmospheric conditions); (2) health policies and adult learning education (HPALE) interventions; (3) urban spaces (local indoor and outdoor spaces for transit and social-cultural interactions, public or private, with natural physical features (river, lake, terrain). Conclusions: Three forced seasonality phases (positive to negative skew) phases were pointed out as a theoretical framework to explain uncertainty found in the predictive SIR model equations that might diverge in outcomes expected to express the disease’s behaviour.

Defining those systems as a hybrid structure (continuous or discrete variables), the iterated and attracting fixed-point events that constitute the administrative work activities can present asymptotic convergence for all possible metric space solutions. The system modelling from the Lyapunov exponential stability point of view allows the projection of system performance to be oriented, based on collective behaviour phenomena, that is, in other words, the relationship between the number of agents (human resources) and the number of administrative works (workloads) within an administrative workflow hybrid environment. This method can roughly and steadily reveal the definition of productivity and asymptotic stability as a state of endosectorial (among internal sector agents) and exosectorial (among external sector agents) work sharing effect.

It was found that despite traditional forms of transmission of the virus SARS-COV-2 through SIR model equations early detected on 2020, empirical evidences suggested the use of more dynamic mathematical modeling aspects for this equation in order to estimate the disease spreading patterns. The SIR equation modeling limitations were found as far as common epidemic preventive methods did not explain effectively the spreading patterns of disease transmission due to the virus association with the human emergent behavior in a complex network model.

However, the presence of a dynamic fixed point can identify a convergence at iterations for larger time lengths (asymptotic stability in Lyapunov sense). Qualitative (QDE) results show that the average distance between the discontinuous function to the fixed point of the continuous function (for all possible solutions), might express fluctuations of on time lengths (instability effect). This feature can reveal the false empirical asymptotic instability behavior between the given domains due to time lengths observation and empirical constraints within a well-defined Lyapunov stability.

Mainly for the “S” and “R” terms of the equation, the predictive results fail due to confounding environment of variables that sustain the virus contagion within population complex network basis of analysis. While “S” and “R” are not homologous data of analysis, thus with improper topological metrics used in many researches that considers a given SIR model as a global solution of the complex COVID-19 transmission; these terms leads to the asymptotic feature of “I” term as the most stable point of analysis to achieve proper predictive methods globally. Having “I” in its basis of formulation the policies adopted by countries, “I” therefore presents a stable fixed point orientation in order to be used as a predictive analysis of dissemination patterns of SARS-CoV-2 infection within a specific region of daily new cases time series worldwide.

Considering the event as a nonlinear system, and the metrics of analysis consisting of two dependent random variables 0 and 1, with memory and probabilities in maximum finite or infinite lengths, constant and equal to ½ for both variables (stationary process). The expressions of the possible trajectories of metric space represented by each binary parameter remain constant in sequences that are repeated alternating the presence or absence of one of the binary variables at each iteration (symmetric or asymmetric). It was observed that the binary variables X1 and X2 assume on time T_k→∞ specific behaviors (geometric variable) that can be used as management tools in discrete and continuous nonlinear systems aiming at the optimization of resource’s usage, nonlinearity analysis and probabilistic distribution of trajectories occurring about random events. In this way, the article presents a model of detecting fixed-point attractions and its probabilistic distributions at a given population-resource dynamic. This means that coupling oscillations in the event occur when the binary variables X1 and X2 are limited as a function of time Y.

The multiplicity fluctuations are sensitive to QCD phase transition and to the presence of critical point in the QCD phase diagram. These fluctuations also provide baselines for other event-byevent (E-by-E) measurements. In the present article, a modest approach attempt has been made for a logical study of event-by-event (E-by-E) charge fluctuations in the relativistic nuclear collisions of proton-proton (p-p) and nucleus-nucleus (A-A) interactions. Finally, simulations by Monte Carlo Generators (MCGs) have been done and findings were found within good agreements with other works.

This measurement process of the adaptive controller can be resumed as the adjustment of the environmental data through an index of performances defined by each biological organism as an optimization of a given task. A mathematical framework was developed to conduct the pathways related to uncertainty caused by the continuous variables presence within the biological similar system.

The proposed equation and its derivations were formulated through a theoretical framework about information theory, probabilities and complex adaptive systems. By defining a productivity equation for organism-machine-environment interactions, discrete and continuous variables that constitute the systems can be controlled by a mathematical framework where prediction and monitoring aspects of optimization are possible without the limitation of strict empirical methods.

It was observed how variables in these dynamics are in recurrence considering parameters such as time, frequency, iteration and interaction. Variables investigated are the consume, time and supply mechanics. Time series analysis of these variables indicated a possible phase space formation of the phenomena. The main conclusion leads to a nonlinear dynamics of the ecological interactions of the organisms and resources symmetries.

Those parameters mentioned before can start chaotic process in the previous system generating infinite random sequences as Per Martin-Löf suggested in his work "Complexity oscillations in infinite binary sequences". In this way the non ergodic properties of system express observable oscillations in which time lengths regulations can be used as a tool for PDF constraint and phase space formations.

Findings: It was found that several variables affect a public service. Many times policies or other actions try to achieve efficiency in controlling or containing public financial resources. It is not uncommon such actions do not have any determinant or robust effect at their prior objectives due to the nature of phenomena. Research limitations/implications: Government expenditures constitute an event of great complexity with respect to the magnitude of financial units and the budget flow involved in each of these units. In this sense, all the financial units that compose the great public expenditure scenario are inserted in heterogeneous contexts considering the dynamics of geographic, social, cultural and political administrative space of a State. Practical implications: The methods exposed in the paper are important tools to verify how policy, financial, administrative and other dimensions of actions taken influenced a continuous expenditure system. The main objective remained in identifying the strong influence of actions toward random variables that might affect the event.

Based on the current statistical methodologies, multifactorial analysis asso-ciated with fuzzy logic, complex phenomena are analyzed by stating the in-fluence of a variable to others and possibly indicating how complexity works. However, these analyzes have limitations regarding the scope of the samples considering the mechanics of an event determined only by the non-physical quantitative properties of variables. The mentioned limits, refers to not con-sidering the measurement of the variable’s interactions influence in the event by analyzing the frequencies in which the interactions affect the formation and behavior of the expected event. Considering that interactions take place in the physical world, they can present non-observable physical features that in-fluence the event. This observation can point out the periodic function in the production of the complex events that can be observed considering the fre-quency with which the analyzed event occurs in its physical quantitative characteristics.

This observation can point out the periodic function in the production of the complex events that can be observed considering the fre-quency with which the analyzed event occurs in its physical quantitative characteristics.

A primeira parte trata dos modelos clássicos S-I-R e S-E-I-R e, em particular, da determinação do dimensão final e do pico epidémico. A reprodutividade R0 desempenha o papel do parâmetro crítico. A epidemia só ocorre se este parâmetro for superior a 1 e desaparece se a fração da população vacinada estiver acima de um limiar facilmente calculado com base neste parâmetro. As outras duas partes do livro tratam da influência das estações do ano sobre a propagação de epidemias e a persistência de doenças endémicas, quer de um ponto de vista determinístico quer de um ponto de vista estocástico.

During the COVID-19 time, many healthcare organizations found themselves limited in terms of addressing the increased supply and demand and workload generated in hospitals and other healthcare services/products. This complicated scenario has in its base of analysis both the human capability of processing the information generated by new data concerning disease, methods, and technologies to prevent COVID-19 dissemination and computed data treatment of daily new information available in order to predict the behavior of supply chains. Concerning a stage before manufacturing and logistics, and after planning and policies, there is a lacuna where public healthcare organizations need to be able to predict how their infrastructure and daily routines respond to unusual and stressful conditions. For this problem, this chapter focused on the work productivity of the bidding sector responsible for delivering services/goods to the population during 2020–21 in the State of Paraná, Brazil and how it failed to provide correct responses under abnormal conditions imposed by COVID-19.

While “S” and “R” can’t be considered as a global solution of the complex COVID-19 transmission; these terms lead to the asymptotic stable feature of “I” (infectious) term as the most stable point of analysis to achieve proper predictive methods globally for policies measures. To observe this assumption, statistical mode analysis was performed to extract a numerical indicator for “I” compartment. This tool could be used with precise data about when policies in a given country, region or spatial sample started and it is possible to track type and duration of policies with the patterns outputs for each analysis.

Soon, research article will be published about this publication in english version. All information available now are only in portuguese. Analysis of workflows of the Sectorial Administrative Group brings a differentiated methodology to ascertain and plan how the information flows in the infrastructure sector of the Paraná Secretary of State for Education and Sport. The analysis is based on a methodological view based on information theory developed by Claude Shannon (1948), probabilistic systems and nonlinear dynamics. The method leaves aside abstractions with highly complex calculations of these disciplines and allows, in a simple and flexible way, to managers, a careful view on which points of each administrative procedure is necessary to make decisions to minimize the impacts generated by operational and financial inefficiency . Thus, the reader is recommended to read the methodology of this research in order to make comprehensible the paths adopted by the author to favor the management of the flows of information of the administrative work. The union of the disciplines of mathematics-physics and biology with the science of administration is a contemporary possibility of knowledge about the forms of human organization and follows international trends of transcending the frontiers of highly specialized knowledge into professional and research niches, bringing new discoveries focused on the precision and production quality of human labor.

Entre os serviços estão internet, telefonia, água, luz, reprografia, impressão, publicações oficiais, entre outros. Os custos com o fornecimento de serviços anualmente podem chegar a quase R$ 100 milhões de reais anuais e nesse sentido aspectos que visam a redução, contenção ou melhor uso dos recursos financeiros são imprescindíveis para uma administração pública eficiente e de qualidade dos serviços públicos prestados. Este artigo trata de um modelo econométrico de análise das variáveis que compõe o fluxo de despesas contínuas, analisando os resultados obtidos em alguns serviços contínuos em relação ao sentido epistemológico de causa e efeito nos quais as mesmas se inserem.

The period analyzed is from 2008 to 2017 and the purpose of the analysis is to address issues related to expenditure flows from year to year and the causes related to reductions or additions to values, taking into account the investigation of factors that promote or influence these expenses. In order to do this, we used mathematical tools that could help the visualization of events that are often not visible without the use of them, without leaving aside the analysis of the managers involved in the process adopting a global vision of all the servers responsible for the realization of the determined type of continuous service. Also discussed through relevant scientific analysis is an analysis of oscillations in continuous expenditures, making studies to understand these phenomena from the standpoint of nonlinear and complex systems. In addition to the results obtained, a strategy was designed to achieve reduction and / or containment targets for almost all ongoing services. The strategies listed have as a differentiated management characteristic which deals with the extension of actions that do not only remain within the administrative scope of the public agency, but extend to the pedagogical dimension and society. By engaging educational establishments with respect to their essential functions and extending to other sectors of society that participate together in the implementation of some types of ongoing services, this publication generates benefits for sustainability, innovation and human life.

The Secretary of State for Education prepared and implemented in 2016, with the action of the Solidary Selective Collection Commission, its solid waste management project with the intention of contributing to the correct separation and final destination of solid wastes of all types present in the dependencies of its administrative units. Through this project it was possible to obtain great advantages for the society and for the institution in terms of an environmental and socioeconomic development of great relevance. In order to ally and contribute to the work of the Selective Solidarity Collection Commission, GAS (Administrative Sectorial Group) has raised reflections that specifically focus on the issue of paper and aim to disseminate improved ways of working in an administrative environment as well as inform the public workers of the Secretary of State for Education (SEED) in what way is the separation and final disposal of waste paper in this public institution. The reduction in the use of paper is a modern action that has as a subsidy the use of technologies available in our work rooms as a way to replace the unbridled consumption of this resource and provide benefits that will generate for society a better quality of life. It is about abandoning the trivial ways of using paper and replacing it with digital forms.

Many important information and new ideas have been analyzed and collected. Some technical and theoretical aspects practiced by the schools have been pointed out in this publication, which serve as a parameter in the search for alternatives that aim to collaborate towards the correct destination of waste goods and conservation of the environment. These aspects help to understand the evolution of existing knowledge and technologies to effect the correct disposal of waste goods and how we can improve practices that we are culturally accustomed to. Among these aspects are highlighted by type of waste material, the forms of disposal, donation, sale and reuse of materials. The benefits derived from the correct destination facilitate the work of the school in allocating these goods as well as avoiding wastes that could be converted into advantages that the school itself can obtain in performing such procedures. Looking for new experiences, many schools revealed a great plurality in the treatment of waste and these methods of destination were recorded in this publication in order to disseminate information to other educational institutions.

A análise contida no mesmo tem como objetivo abordar questões referentes aos fluxos de despesas de ano a ano. Para isso foi utilizado ferramentas matemáticas que pudessem auxiliar a visualização de eventos que muitas vezes não são visíveis sem o uso das mesmas. Trata-se da utilização da econometria, e nesta área, a função estatística conhecida como coeficiente de determinação, ao qual é empregada comumente na economia para entender variáveis econômicas através da aplicação de um modelo matemático. O coeficiente de determinação (R²) se baseia nos dados obtidos pelas despesas anuais de ano a ano, assim, é um modelo que se alimenta de dados reais, concretos. Este procedimento empírico de análise, porém não é suficiente para descrever a realidade em todas as suas expressões, de modo que análises teóricas dos gestores são necessárias e complementares ao modelo matemático (ver página 14 - Limites em oscilações periódicas). A análise do gestor traz percepções, experiências próprias e conhecimento de causa que aproxima mais o modelo matemático e a possibilidade do mesmo conter erros, da realidade. O modelo matemático por não poder contemplar todo o mundo real tendo em vista suas características propriamente indutivas, sugere epistemologicamente a necessidade da ação humana em suas características propriamente dedutivas, reforçando com precisão a análise da realidade.

Este relatório traz informações importantes sobre quais publicações são mais utilizadas na SEEDPR, as quais dentre elas, estão, o Diário Oficial do Estado – DIOE, Diário Oficial da União – DOU e jornais credenciados que correspondem a 32 jornais em 21 regiões administrativas no Estado do Paraná. Também é investigado quais publicações são as mais caras no contexto de despesas finais das publicações analisando dados registrados no ano de 2014 e começo de 2015, o que é suficiente para entendermos de modo breve quais são os comportamentos deste tipo de despesa e de que forma o usuário, produtor de publicações pode contribuir para a correta diagramação e efetividade no uso do dinheiro público. Desde 2011 até 2014, o número de publicações neste órgão tem crescido e com isso também, os custos das mesmas. De 2011 até 2014 o Diário Oficial da União teve um crescimento de 1780% em aumento de despesas. O Diário Oficial do Estado ficou com 66% de crescimento, e por fim os jornais credenciados finalizaram o ano em 68% de aumentos com as despesas em publicações veículadas por setores de nossa Secretaria (BRASIL, 2015a). Estes números revelam que há necessidades de reduzir os valores gastos com publicações e para isso, são necessárias pequenas mudanças in locu nas publicações produzidas pelo órgão em questão.

Em maio de 2014, realizou-se um levantamento nas instituições de ensino que fazem aproveitamento de água de chuva e ficou constatado que de 2248 instituições, apenas 68 fazem a captação das águas pluviais. Neste sentido foi elaborado este material para eventuais consultas e planejamento, envolvendo questões básicas para instalação e funcionamento de coletores de água de chuva. Apresentamos um modelo para aproveitamento de água da chuva que acreditamos ser acessível à maioria das instituições de ensino. Trata-se de reaproveitar a água da chuva para fins não potáveis, ou potáveis dependendo da necessidade e possibilidade de cada estabelecimento. Podendo esta ser a forma mais simples de coleta com baixa capacidade, cerca de 200 litros, ou coletores mais especializados com maior capacidade, dependendo dos objetivos de uso desta água por parte da escola. Esta publicação apresentará entre outros, métodos de coleta, tratamento da água, benefícios da coleta, e ao final, como instalar uma bombona de 200 litros para coleta de água pluvial. O custo para implantação deste sistema não é alto se considerarmos apenas um barril coletor (bombona) e demais materiais necessários. Ao se definir os objetivos no uso desta água, é possível também estimar a quantidade de materiais necessários para implantação do coletor, bem como, em longo prazo, evitar efeitos de escassez de água que ocorre em algumas regiões de nosso Estado. A redução do consumo deste recurso pelas instituições de ensino posiciona as mesmas como instituições que fomentam a sustentabilidade ambiental e são gestoras no uso dos recursos financeiros e ambientais na administração pública.

Observing time series data of daily new cases of COVID-19 worldwide, the epidemics birth and death persistence present different outcomes for each country of observation, with many delays and fluctuations for the outbreaks, peak and control phases. These data with distinct outcomes among countries originate false phenomenon observations to predictive analysis based on SIR (Susceptible, Infectious, Recovered) models and its derivations. This is due since these models rely upon defined types of health policies interventions, pre-assumed human behavior and predefined spatial or temporal analysis. To overcome these limitations of SIR model equation and in order to identify an endemic stability of the disease, it is mandatory to elucidate the mixture of variables that sustain an indeterminate pattern of growing or reduction rates among countries.
We invite researches from interdisciplinary fields to contribute with this special issue, covering the topics, but not limited to:
1. Epidemiological models
2. SIR model limitations
3. COVID-19 mathematical modeling
4. Nonlinearity
5. Bifurcation and Stability
6. COVID-19 seasonality patterns

Tradicionalmente, o uso final de água por edifícios públicos ocorre de modo semelhante ao consumo residencial, comercial e industrial [2,4], porém, quando as variáveis que compõe o uso do recurso se expressam de modo instável [5], apresentando oscilações que variam bruscamente, as metodologias comerciais para o uso final do recurso enfrentam limitações quanto a forma de predição e identificação desses excessos do consumo. Nesse sentido, os métodos apresentados nessa pesquisa buscam contribuir com análises de consumo oriundas de sistemas complicados.

The author sought to gather contents aimed at the understanding of the needs of the deaf communities in Brazil by the hearing community. It is recommended to use the material associated with the reader's own knowledge, since many of the topics covered were not explained literally in the slides, but are orally reproduced for the students to which this presentation was intended. Knowledge should always have been free and widely accessible to all. The main purpose in making knowledge as a public object and free access is the promotion of human life. It is understood that knowledge exists to make social and productive life more solidary and permeated by the culture of peace. The current model of using knowledge for reproduction and profit is a model that can not be sustained in times of crisis of humanity. Thus, the main goal in making this material public as an Open Presentation Courseware is to disseminate knowledge in a broad, free, and unrestricted way. It is understood that knowledge sharing so that other professionals can improve performance is a path that humanity strongly needs, when one thinks of how knowledge can solve small and large problems in the daily routine of many Brazilians and promote the improvement of society as a whole. Free access to professional enhancement through self-taught practices is, according to the Open Education Consortium and MIT Open Learning, a worldwide trend to be adopted so that inequalities and individual freedom of human life can reach their maximum degree of completeness. This Open Presentation Courseware is a biannual lesson plan that addresses traditional themes of the Brazilian Sign Language as required by the Brazilian Ministry of Education. However, other approaches on deaf / deaf subjects are explored and taught to undergraduates and other baccalaureate students who have a low frequency of inclusion of the LIBRAS discipline in their curriculum (such as administration, engineering, medicine, etc.). ). It is suggested that this presentation be used as a source of resources for new and experienced teachers, either in higher education or other modalities in which the deaf person is inserted.

The main objective was to represent the network among visual communication, sign language and deaf/hearing people cognitive approaches to reality. The image shows accessibility for deaf people towards institution dependencies. To represent a visual world in its subjectivity is a challenge of trying to see the other's mind and in that case, the deaf mind and hearing mind. The panel assumes limitations in put one world into other at same multicultural space of individuals by being hearing ones and deaf ones. The main idea proposed is "How to share information of reality optimizing elements present and absent for the senses?" The limitations with which the banner challenge to surpass can be tracked as: - Lexical, both by spoken and sign language. There are not enough words or signs to represent reality for both worlds; - Language Processing, both by spoken and sign language towards working memory. There are not enough memory for sequencing the complexity of spaces for deaf or length of words for hearing; - Semantics. Both spoken and hearing share in its own domain a subjective meaning towards visual orientations (phenomenology); - Complexity. Language as capable of "Hearing with the eyes and see with the ears"; - Unspeakable. Where language is intangible to the own senses as primary effect of know something with the senses.

Human cognitive productivity and lack of closed-loop control tool of these processes can generate biases/uncertainties in relation to expected work outcomes. It happens because information systems have a black box output performance towards operating continuous variables generated by agents as an input feature of a given system. Most information systems (workflows) designed to support human life operates as an AI data storage and discrete data processing among agents but have limitations on processes where individual performance may impact final outcomes. With respect to evaluate how cognitive work performance have tendency to success or failure rates, machine and human interactions need to be observed in terms of how productivity can find itself in a status as overloaded, dismantled and chaotic patterns of production.

My research focused on how public sector deals with information flow in its administrative workflow specifically, this research analyzed educational workflows in a massive system that is composed of more than 2500 administrative units.
And what does it in relation with the entropy concept?
As far as the volume of information raises within a system, also raises uncertainty and complexity of how a work should be executed aiming for efficiency and efficacy to population. This point is very connected with some parameters of how to perform a given work activity in a public system, that is the discretization of information, computerization, work sharing and finally, or mainly, the individuals who processes information. It is not uncommon that public administration finds some limitations in address to the citizens, for the best performances for public services or really supportive infrastructure. Also, it’s not uncommon that in public sector come up with totally poor quality of information, services or political planning available to citizens considering it the vertical degree of organization that we know as top down approaches.
When we have very precarious systems, the information used to execute a work tends to be individualized, under subjectivity scales, or discretization of information and knowledge applied to the whole public system is not well performed as well as understood, leaving individuals to create their own methods or finally, a computer program or ability to use this program is available in certain administrative units while others use distinct methods.
