Port Community Systems have become a staple technological platform used to exchange information between the public and private agents and entities involved in ship and cargo services within seaports. In this paper, the theoretical background of the Port Community System is provided, emphasizing the importance of its implementation, and stakeholder collaboration. Different models of introducing an integrated Port Community System in seaports are analysed using literature review and actual cases in some of the most prominent seaports.
Four Domains of Public Value Creation: A Core Typology
Authors: Joyner Dr Kate
Published: July 2021

The public management literature has failed to capture the arenas of operation of the public sector manager in one holistic framework, thus inhibiting the development of a more complete theory of leadership that drives public value. This paper develops a core typology of arenas of public value creation, based on the locus of interaction (internal or external to the government organisation) and the public value purpose (trading or policy development). Four arenas are described, illustrating that public sector managers in complex policy areas traverse all forms of institutional structure includingmarket, hierarchy and hybrid. The typology developed and discussed is an attempt to provide more precision in characterising the nature of policy leadership. Building on the public value work of Moore (1995; 2013; 2014),the typology enables theorising on the role and nature of leadership in driving public value.
Corporate Governance in EU Agencies: The Europol Case
Authors: Orlandi Eugenio
Published: July 2021

There is a trend in government to establish semi-autonomous public organizations, “Agencies”, to carry out public tasks, implement policies, regulate markets and policy sectorsor deliver public services. Once an Agency is established, it is necessary to ensure proper governance. Object of this paper is to answer three Research Questions. RQ1: “Is EU Agencies governance subject to change over time”? If the answeris “Yes”, a second question (RQ2) pops up: ‘Why EU Agencies’ governance is subject to change?” Last but not least, change has to be implemented. The topic is developed in relation to the choice made by the European Union,the one-size-fits-all modelthat makes the work of controllers simple. Are we sure that such a model“is the best choice for EU Agencies’ governance?” (RQ3). If RQ1 is self-evident, more interesting are RQ2 and RQ3 because explain the nature of change (Why) and How change was introduced. In this quest, the tasks assigned to the Board of Directors and the Executive Directorare mapped against Agencies’ mission. In the case of the European Police Office, in eight years three founding acts-an international Convention, a Council decision and a Regulation - have changed the tasks of the Board of Directors and of the Executive Directorin line with the evolution of the political scenari: from intergovernmental cooperation to a policy assigned by the Lisbon Treatyto the European Union.

Published: July 2021

We introduce a class of neighbourhood frames for graded modal logic embedding Kripke frames into neighbourhood frames. This class of neighbourhood frames is shown to be first-order definable but not modally definable. We also obtain a new definition of graded bisimulation with respect to Kripke frames by modifying the definition of monotonic bisimulation.
The Issue of Representativeness in the Lights of the Amended Trade Unions Act
Authors: Sierocka Iwona
Published: July 2021

The subject of the deliberations are issues regarding the representativeness and size of workplace trade union organisations after the changes introduced in the Trade Unions Act in 2018. According to the obligatory provisions, the “representativeness” of a trade union organisation is traditionally conditional on its size, but not only the employees, but also other categories of the employed are taken into account. It is, inter alia, about persons providing work under a contract of mandate or a specific work contract and sole proprietors. By expanding the full rights of coalition onto persons performing work on the basis other than employment relationship, the legislator increased the percentage limits decisive in the matter of representativeness. At present, the representative trade union organisation above the workplace level is also an organisation uniting at least 15% of all people performing gainful work under the articles of association, not fewer, however, than 10,000 persons performing gainful work. It works similarly at the workplace level. With reference to workplace trade union organisations which belong to organisations above the workplace level which meet the criteria for representativeness as specified in the Social Dialogue Council Act, at least 8% of the staff of the given employer is required. In the case of workplace trade union organisations which do not participate in such structures, the representativeness is conditional on uniting of at least 15% of persons performing gainful work for the given employer (7% and 10%, respectively, were required earlier). Determining the number of the staff, the employees and persons providing gainful work under other bases being employed for at least 6 months before the commencement of negotiations or arrangements must be included. A significant novelty is the necessity to select a joint representation of the representative organisations at the workplace level that belong to the same Trade Union Federation or National Trade Union Confederation in matters regarding collective rights and interests of the persons performing gainful work.
The Right to Strike and Other Forms of Protest of Persons Performing Gainful Employment Under Civil Law
Authors: Tomanek Artur
Published: July 2021

This article deals with the issue of extending the right to conduct a collective labour dispute to persons performing paid work under civil law contracts, after the entry into force of the Act of 5 July 2018 amending the Act on Trade Unions and Certain Other Acts (Journal of Laws 2018, item 1608). The author considers the question whether and to what extent the right to strike and to take industrial action, provided for in the Act of 23 May 1991 on Resolution of Collective Disputes (consolidated text: Journal of Laws 2020, item 123), extends to civil lawful contractors. The position is presented that the proper application of the above mentioned law to the indicated circle of work contractors cannot mean the deprivation or limitation of their right to strike and to take industrial action. The solutions implemented by the Polish legislator with regard to persons performing work outside the employment relationship are more advantageous and far-reaching in comparison with the requirements resulting from the international labour law acts binding on Poland. However, there are specific problems with applying to these persons some of the regulations included in the Act on Resolution of Collective Disputes. These problems results from the fact that the individual legal relationship between these persons and the entities employing them is based on the provisions of civil law, and not on the Labour Code.

O Palácio Itamaraty em Brasília: uma análise a partir da sintaxe da linguagem visual
Authors: Brandão Claudio Roberto Comas
Published: July 2021

O Palácio Itamaraty, sede do Ministério das Relações Exteriores, é considerado uma das obras referenciais do arquiteto Oscar Niemeyer e é um dos edifícios de destaque na Esplanada dos Ministérios em Brasília. Este trabalho tem por objetivo analisar o edifício à luz das ferramentas da sintaxe visual. A análise se fundamenta nos atributos visuais e regras de composição descritos pela professora Donis A. Dondis em seu livro Sintaxe da linguagem visual e busca suprir a ausência de um memorial descritivo que explicite as intenções do arquiteto. O objeto de estudo é analisado em três escalas: no contexto urbano, na composição dos volumes do complexo do ministério e na escala do edifício, neste caso, o palácio. Espera-se com isso complementar as recentes pesquisas sobre o Palácio Itamaraty e dar subsídios a novas hipóteses sobre este objeto.

Authors: Broto Arif Hadi , Miarsyah Mieke , Ristanto Rizhal Hendi
Published: July 2021

Natural science learning during the Covid-19 pandemic has quite a high challenge because students and teachers cannot learn directly. Knowing the effectiveness of using Google-site as a material and media for student learning during distance learning to improve student learning outcomes is the aim of this study. This research was conducted at SMP PGRI 1 Karang Tengah Tangerang in grade 8. Purposive sampling was carried out for sampling in this study, so that class 8-E was the experimental class and class 8-E was the control class. The results showed that the use of Google-site as teaching materials and learning media was feasible. The use of Google-site as teaching materials and learning media has no significant effect seen from the Mann Whitney test of 0.419. The average N-gain test obtained from the control class was 0.029, while the experimental class was 0.051. The comparison of the mean value of the control class pretest and posttest was 1.4 points, while the average score of the ecaperimen class was 3 points. Based on this, it can be concluded that the use of Google-site as a material and media for student learning during distance learning can be used to improve student learning outcomes. However, several revisions are needed so that teaching materials and media are more effective in improving student learning outcomes independently.

Published: July 2021

Introduction: Population-based disability prevalence estimates are limited for New York City (NYC). We examined the associa­tion of several health and health-related measures with disability among NYC resi­dents aged 20-64 years.Methods: We used information from 1,314 adults who participated in the 2013-2014 NYC Health and Nutrition Examination Sur­vey (HANES). We categorized survey partici­pants as having a disability if they reported a physical, mental, and/or emotional problem preventing work or if they reported difficulty walking without special equipment because of a health problem. We used log-binomial regression to quantify the association of each exposure with disability before and after adjustment for select covariates.Results: Overall, 12.4% of the study’s NYC residents aged 20-64 years had a disabil­ity. After adjustment, disability prevalence was significantly greater among those who reported having unmet health care needs (prevalence ratio [PR] = 1.75, 95% CI: 1.18-2.57) and those who reported fair/ poor general health (PR = 2.33, 95% CI: 1.68-3.24). The probability of disability was greater among NYC residents with arthritis (PR = 2.66, 95% CI: 1.85-3.98) and hy­pertension (PR = 1.48, 95% CI: 1.04-2.11) when compared with those without these conditions. Disability was also associated with depression (PR = 2.96, 95% CI: 2.06- 4.25), anxiety (PR = 2.89, 95% CI: 2.15- 3.88), and post-traumatic stress disorder (PR = 2.55, 95% CI: 1.66-3.91). Disability, however, was not associated with diabetes.Conclusion: Disability is more prevalent among those with unmet health care needs, fair/poor general health, arthritis, hyperten­sion, depression, anxiety, and PTSD in these NYC residents, aged 20-64 years. These findings have implications for NYC’s strate­gic planning initiatives, which can be better targeted to groups disproportionately affect­ed by disability.Ethn Dis. 2021;31(3):445- 452; doi:10.18865/ed.31.3.445

Published: July 2021

Introduction: Coronavirus Disease 2019 (COVID-19) has become a pandemic. Much false information was circulating especially through social media and affected individual’s knowledge, attitude, practice (KAP) towards COVID-19. Currently, there is lack of validated questionnaires to assess KAP about COVID-19 especially in Indonesian young people.

Aim: To develop and validate a new COVID-19 KAP questionnaire for young people population in Indonesian language.

Methods: Some literature review was done to look for the concept to generate a new questionnaire.  Open-ended questions were generated to know the baseline knowledge. Then, close-ended questions were formulized for knowledge, attitude, and practice area. The experts and several respondents were asked to give their opinions about the contents of the questionnaire. The validity was examined using Cronbach's alpha coefficient. For reliability, internal consistency was examined by using Pearson or Spearmen correlation test.

Results: A total of 59 subjects with median ages 21 (16-24) years old of non-medical individuals were included in this validation process. More than half were male, mostly held bachelor’s degree/diploma, and were dominated with students. This Indonesian COVID-19 KAP questionnaire for young people consists of 10 knowledge, 8 attitude, and 7 practice questions. The Cronbach’s alpha coefficient of knowledge, attitude, and practice areas were 0.87, 0.82, and 0.91, respectively.

Conclusions: A questionnaire of KAP towards COVID-19 in Indonesian language had been developed and the results showed good validity.

Background : As a result of the COVID-19 pandemic, Indonesia implemented various policies to break the chain of transmission of COVID-19, starting from large-scale social restrictions, quarantines, and even lockdowns. Without exception, schools were also closed. These conditions affect people psychologically, including levels of depression, anxiety, and stress in students. The aim of this study is to determine profile and factors associated with depression, anxiety, and stress in Indonesian people during the COVID-19 pandemic.

Methods : A cross-sectional study among students in Indonesia was conducted to determine depression, anxiety, and stress levels in adolescents based on their sociodemographic characters. The DASS-21 questionnaire was distributed online.

Results : A total of 913 people participated from all provinces in Indonesia. Depression, anxiety, and stress were found in 43.5%, 43.3%, 25.2%, respectively. The severity of depression was significantly associated with age (p<0.001), gender(p=0.003), and region(p=0.039). Adults (25-55) are 4.6 times odds more likely to have depression than adolescent during pandemic (OR=4.641, 95% CI=2.053-10.491). The severity of anxiety was significantly associated with age (p=0.002), gender(p<0.001), education (p=0.004) and region(p=0.004). The severity of stress was significantly associated with gender (p<0.001) and education (p=0.018).

Conclusion : Depression, anxiety and stress quite common found in Indonesian during COVID-19 pandemic. Several sociodemographic factors were associated with depression, anxiety and stress among Indonesia

Published: July 2021

Considerada um marco para a gestão de resíduos sólidos no Brasil, a Política Nacional de Resíduos sólidos foi instituída em 02 de agosto de 2010, através da Lei n° 12 305. Essa lei distingue os termos destinação e disposição de resíduos, determinando que para esse último sejam encaminhados apenas rejeitos, ou seja, materiais para os quais não existe tecnologia disponível para reaproveitamento. Em 2018 foram geradas 79 milhões de toneladas de resíduos no país, desse total 72,7 milhões foram coletadas. Do total coletado, 59,5% foram destinados a aterros sem qualquer aproveitamento. Nesse contexto, esta pesquisa objetivou a comparação de custos para instalação de uma Central de Tratamento de Resíduos (CTR), composta por pátio de triagem para recicláveis secos, pátio de compostagem e aterro de rejeitos, com aterros de resíduos sem segregação. Realizado no município de Uberaba, o estudo estabeleceu o horizonte de projeto de 20 anos. Para as estimativas, consideraram-se a área necessária para instalação de cada unidade de disposição e destinação, os sistemas de drenagem das águas superficiais, do lixiviado e dos gases, bem como o tratamento do líquido percolado. Para projeção dos custos, foi utilizado o Sistema Nacional de Pesquisa de Custos e Índice da Construção Civil. Em todos os aspectos verificados, a central de recebimento de resíduos superou os benefícios do aterro de resíduos, apresentando menor área requerida, aumento da vida útil e menor custo de implantação
MONITORAMENTO ENERGÉTICO NO AMBIENTE HOSPITALAR
Authors: Francisco Mauricio Fernando , Vazquez Gisele Herbst
Published: July 2021

A maior parte dos danos à saúde pública e ambiental são produzidos pelo consumo de energia a partir da queima de combustíveis fósseis, como o petróleo, o carvão e o gás. O setor de saúde consome quantidades consideráveis de energia, porém, é impossível desenvolver um plano de ação sem monitorar e conhecer de fato os dados referentes a este consumo, havendo assim, a necessidade sistemática da realização de medições. Este trabalho tem como foco principal monitorar o consumo energético do hospital da Unimed Regional Jaú, que está em fase de construção, com inauguração prevista para outubro de 2020. Inicialmente, a medição será realizada por alas, que para uma maior eficiência deverá avançar a nível de leitos e equipamentos. No entanto, para efetuar o monitoramento, foi desenvolvido um equipamento eletrônico utilizando arduino (plataforma de prototipagem eletrônica de hardware) e demais materiais como sensor de corrente, resistores, transistores e capacitor, que foi instalado em uma sala contendo servidores na operadora do plano de saúde, com o objetivo de testar o seu desempenho. Os dados coletados foram armazenados e exibidos por meio de dashboards no site OpenEnergyMonitor. Concluiu-se que após o processo do desenvolvimento do sistema de gestão e supervisão de monitoramento de energia elétrica, novos conhecimentos foram adquiridos de forma a solucionar as dificuldades encontradas. O objetivo por trás de cada decisão na arquitetura do projeto foi sempre garantir que o sistema fosse dinâmico, prático de montar e principalmente de baixo custo, na compra e manutenção. Hoje existem sistemas semelhantes no mercado, porém nenhum utiliza a tecnologia aplicada neste sistema. Assim, verificou-se com satisfação, que existe lugar no mercado para o equipamento desenvolvido. Contudo, o valor pelo qual se pode adquirir um destes sistemas de monitorização, ainda é elevado para a grande maioria da população.

Published: July 2021

As Unidades Básicas de Saúde (UBS) e as unidades de Estratégias de Saúde da Família (ESF) são estabelecimentos que prestam serviços de atenção básica à população de um município. O gerenciamento dos Resíduos de Serviços de Saúde (RSS) gerados por estas unidades acontece por etapas interdependentes cuja finalidade é preservar o bem-estar dos funcionários, conservar o meio ambiente e dar segurança à população. As etapas do gerenciamento devem ser realizadas com base em uma percepção ambiental bem estruturada, de forma sistêmica. No Brasil há uma extensa legislação que regulamenta a questão junto às unidades geradoras. O presente estudo objetivou analisar o gerenciamento desses RSS em UBS’s e unidades de ESF’s do município de Ilha Solteira, no período de 2011 a 2018, utilizando-se da pesquisa bibliográfica e documental, associada à observação e registro fotográfico das ações de gerenciamento adotadas pela administração municipal. Constatou-se que o município possui um Plano de Gestão Integrada de Resíduos Sólidos que, desde 2012, estabelece o correto gerenciamento dos resíduos, como obrigação dos gestores da saúde e demais trabalhadores destas instituições. Contudo, falta conhecimento sobre a importância do processo para a manutenção de um ambiente salutar para a comunidade. A eficiência na prestação dos serviços é uma busca constante, mas falta atenção em pontos fundamentais. Conclui-se que o sistema necessita de maior aprimoramento. Investimentos na educação continuada, treinamento dos profissionais de saúde e esclarecimento da população mostram-se fundamentais para a solução das questões que envolvem o gerenciamento adequado dos RSS e o correto cumprimento da legislação. Palavras-chave: Educação continuada. Gestão. Legislação. Saúde Pública. Unidades geradoras.
AVALIAÇÃO PÓS-OCUPAÇÃO AMBIENTAL NO CONJUNTO RESIDENCIAL SANTO ANTÔNIO – SALGUEIRO-PE
Authors: Andrade Yanne Pereira de , Santos Jheymisson Santana Alves , Rêgo Rejane De Moraes
Published: July 2021

Apesar do investimento do governo em políticas públicas buscando sanar os problemas da habitação social, pode-se observar que muitas vezes os projetos são aplicados sem a adequada identificação das necessidades dos usuários, além da implantação de projetos padronizados sem a devida adequação às condicionantes climáticas locais e às práticas sustentáveis de conforto e desempenho térmicoenergético. Nesse contexto, a Avaliação Pós-Ocupação constitui-se em um instrumento relevante, com potencial de contribuir para a melhoria das residências construídas pelo Programa Minha Casa Minha Vida (PMCMV), principal política governamental em vigor para Habitação de Interesse Social no Brasil. Desta forma, o presente artigo apresenta o estudo de caso realizado no Conjunto Residencial Santo Antônio situado no município de Salgueiro, na região do sertão central de Pernambuco, que objetivou aplicar a Avaliação Pós-Ocupação (APO) em Habitação de Interesse Social (HIS) para analisar a qualidade do ambiente construído e a adequação de técnicas e de materiais adotados quanto às exigências estabelecidas pela Norma de Desempenho das Edificações Residenciais – NBR 15.575, além de avaliar a adequação às condicionantes climáticas locais. Para isso, a pesquisa utilizou procedimentos metodológicos tanto qualitativos quanto quantitativos da APO Ambiental em habitações. Como resultado, o estudo de caso realizado verificou que há atendimento parcial às normas pra conforto e desempenho térmico-energético pelo uso de algumas técnicas construtivas sustentáveis, possibilitando concluir que: (1) a utilização de práticas sustentáveis na construção de Habitações de Interesse Social está presente nas construções mais recentes, mas ainda precisa ser melhor explorada; (2) as habitações existentes são suficientes para atender as necessidades básicas da habitação, mas precisam melhorar no que diz respeito à garantia de condições de conforto aos moradores; (3) a realização de APO em habitações construídas por programas governamentais tem potencial de contribuir para a melhoria dos mesmos apontando deficiências e soluções que resultarão na melhor qualidade de vidas dos moradores.
COMPRAS PÚBLICAS SUSTENTÁVEIS E O DESENVOLVIMENTO LOCAL: O CASO DO PROMOVE E AS CADEIAS DE MÓVEIS DE PARINTINS, AMAZONAS
Authors: Lopes Kamille Vieira , Pereira Henrique Dos Santos
Published: July 2021

Políticas públicas quem incentivam a economia solidária e sistemas produtivos locais podem resultar em ações que favorecem o desenvolvimento regional sustentável. Esta pesquisa procurou aprimorar o entendimento sobre os impactos de uma política pública baseada em compras públicas sustentáveis, o Programa de Regionalização do Mobiliário Escolar – PROMOVE, sobre as dinâmicas socioeconômicas e ambientais de um sistema produtivo regional, no caso as cadeias de móveis na cidade de Parintins, no estado do Amazonas. Além da avaliação de indicadores de desempenho ambientais e econômicos das cadeias, foram analisados o estágio do capital social e as estruturas da rede de relações entre gestores moveleiros e agentes públicos. Os dados foram obtidos mediante observações diretas e aferições in loco do desempenho dos processos produtivos e por meio de entrevistas semiestruturada. Os resultados demonstram que relacionar o entendimento dos fatores produtivos e econômicos às análises de capital social e às políticas públicas de fomento são fundamentais para o entendimento da dinâmica de um sistema produtivo regional. O Promove favoreceu a integração dos atores moveleiros, a criação de capital social e físico. Porém, ressalta-se que são necessários maiores níveis de articulação interna e externa dos gestores das cadeias de móveis para que o grupo amadureça seu capital social.

Published: July 2021

O estudo teve por objetivo analisar a percepção da população de Naviraí/MS sobre a gestão de resíduos sólidos urbanos. Foram aplicados questionários e considerados 457 válidos para a composição do artigo. Descobriu-se que 30,77% das pessoas que possuem uma renda de dez a vinte salários mínimos discordam parcialmente em separar o lixo orgânico do reciclável. E 22,22% das pessoas que possuem até um salário mínimo são indiferentes ao assunto. Em relação à afirmação sobre relação a colocar o lixo todo dia para fora de casa, independentemente se é orgânico ou reciclável, 52,94% das pessoas que tem o ensino fundamental incompleto concordam totalmente em relação a colocar o lixo todo dia para fora de casa e 22,08% das pessoas que têm ensino superior completo discordam totalmente que fazem esta atividade diariamente. Através do método de regressão múltipla encontrou-se uma relação positiva entre a ação colocar o lixo para fora todos os dias e a escolaridade dos respondentes, mostrando que quanto maior a escolaridade das pessoas também maior é a probabilidade de que haja este hábito diário.

Published: July 2021

Este trabalho tem como objetivo descrever como se configura o campo de pesquisas científicas sobre Nature-Based Solutions (NBS). Este trabalho é uma revisão bibliométrica de literatura. A revisão bibliométrica utiliza dados quantitativos para analisar a produção bibliográfica sobre um determinado tema e ajuda os pesquisadores a encontrarem trabalhos relevantes, concentrações de pesquisas e temas em que os estudos estão focados, países proeminentes na área de pesquisa, palavras-chave e autores mais citados, obras mais referenciadas, entre outros aspectos. No que tange aos procedimentos metodológicos, utilizamos a proposta de sistematização de Prado et al. (2016). Concluímos que as pesquisas sobre NBS ainda são incipientes, mas que apresentaram crescimento nos últimos anos. Os estudos destacam a possibilidade de aplicação em diferentes áreas como crise hídrica, agricultura, infraestrutura verde e mudanças climáticas. No final, destacamos a pertinência de pesquisas no Campo de Públicas e de Ciências Administrativas sobre soluções baseadas na natureza e as possibilidades do desenvolvimento de políticas públicas a partir desta ótica. Enfim, desenvolver a NBS é ter em mente que a própria natureza é a solução para os problemas.

Os indicadores de sustentabilidade nas organizações visam mensurar e compreender responsabilidade das dimensões ambientais, sociais e econômicas. Este trabalho avaliou a sustentabilidade de uma empresa produtora de carvão vegetal no semiárido paraibano. O Índice de Sustentabilidade Empresarial (ISE) foi aplicado para avaliação da sustentabilidade. Este indicador possui quatro critérios: (i) política, (ii) gestão, (iii) desempenho e (iv) cumprimento legal. A partir das análises realizadas, foi observado que a aplicação do ISE se apresentou adequada na avaliação de sustentabilidade da empresa, buscando avaliar as práticas sustentáveis e inovadoras para o setor de carvoejamento. Os resultados revelaram que a empresa considera importante a prática de ações ambientais, mas não as pratica totalmente e ainda não demonstra interesse em conhecer as ações praticadas pelas empresas cujos índices são mais elevados dentro dos parâmetros do ISE. Apesar da empresa conhecer sobre o assunto e das práticas ambientais aplicadas ao setor, existe uma carência significativa na aplicação destas práticas. Notou-se também que o objetivo principal das poucas ações praticadas pela organização concentra-se no cumprimento legal e/ou na redução de despesas, ambos em consequência da economia de recursos.

Published: July 2021

A distribuição da água em um determinado território nem sempre condiz com a disposição demográfica. Diversos fatores contribuem para essas diferenças, apesar do homem procurar se estabelecer em locais próximos às fontes de água ou em lugares que ao menos forneçam o mínimo para o seu consumo. Por diversas circunstâncias, entre elas, a poluição ambiental, há uma maior necessidade de investigação, e desta forma, recorre-se a meios alternativos para solucionar ou mitigar os danos causados aos recursos naturais, principalmente aos recursos hídricos. A este último, apresentam-se como alternativas o reuso da água do esgoto e o aproveitamento das águas pluviais após o devido tratamento para a finalidade a qual se destina.  Com base nesses sistemas e por meio de pesquisa exploratória, utilizando materiais bibliográficos e documentais, é possível descrever a viabilidade ambiental e a relevância de pequenas atitudes que podem proporcionar benefícios ao meio ambiente e a população. Desta forma, este trabalho objetiva demonstrar o quão importantes e eficientes são as medidas previstas na legislação para a diminuição da poluição ambiental e o consequente aumento da preservação hídrica.
INSTRUMENTOS ECONÔMICOS DE INCENTIVO À GESTÃO DE RESÍDUOS SÓLIDOS NO CONTEXTO BRASILEIRO
Authors: Monteiro dos Santos Kaynã , Soares de Castro Marco Aurélio
Published: July 2021

Instrumentos Econômicos (IEs) podem complementar a atuação dos Instrumentos de comando e controle para a consecução de objetivos de políticas ambientais, incentivando comportamentos ambientalmente desejáveis. Se aplicados à gestão de resíduos, poderiam estimular a redução na geração, o descarte adequado, e mesmo a estruturação de sistemas de coleta seletiva, pela atribuição de valor econômico de produtos e serviços que contribuam para a proteção da saúde pública e qualidade ambiental; um exemplo são os IEs baseados em Pagamento por Serviços Ambientais (PSA). Este trabalho aborda o papel dos IEs no contexto da gestão de resíduos no Brasil, apresentando bases legais e experiências de implementação nas esferas federal, estadual e municipal. A pesquisa compreendeu uma revisão bibliográfica de artigos, teses, dissertações e livros, bem como dispositivos legais em vigor; e múltiplos estudos de caso abordaram iniciativas baseadas em IEs. As abordagens dos instrumentos identificados dividem-se entre a precificação de produtos e serviços e a criação de mercados; os IEs voltados para a valoração de serviços ambientais podem beneficiar cooperativas de catadores e mesmo os cidadãos em geral. No entanto, a própria PNRS não traz regulamentações específicas sobre a implantação dos IEs; parte das iniciativas inicialmente investigadas foi encerrada; e a recente Política Nacional de PSA não traz qualquer disposição aplicável à gestão de resíduos sólidos. A falta de uma regulamentação ampla e de continuidade nas iniciativas pode impedir significativamente as contribuições dos IEs ao aumento da eficiência no setor.
The impact of supply pressure on gas injector expenditure characteristics
Authors: CZARNIGOWSKI Jacek
Published: July 2021

The paper analyzes the changes in an LPG injector flow mass characteristics when input pressure is altered. The research was carried out at a test stand with an air-supplied injector. The test results (the pressure both before and behind an injector, a control signal and the current flowing through an electromagnetic coil) were analyzed for the impact of pressure on the injector characteristics. The analysis deals with a pressure effect on a unit mass flow, injector opening dead time (minimum time of a signal that causes an opening), the characteristics linearity, and its intersection point with a time axis. There was also analyzed a single injection time course, particularly emphasizing injector valve opening and closing time. It has been stated that the increase in pressure results in the increased unit mass flow and the simultaneous increase in injector dead time as well as a shift of the intersection point with a time axis along this axis.

History and future of turbine aircraft engines
Authors: OPARA Tadeusz
Published: July 2021

This paper discusses stages of development of air propulsion from piston engines up to three-rotor turbine ones.
Limitations in speed and altitude of flight, caused by traditional system of a piston engine and an airscrew, became an
impulse to conduct research on jet propulsion. Accomplishments of the designers of the first jet-propelled engines:
F. Whitle and H. von Ohain are a reflection of rivalry in this field. In the second half of the 20th centur y turbine propulsion
(turbojet, turboprop and helicopter engines) dominated air force and civil aviation. In 1960 the age of turbofans
began, owing to better operating properties and electronic and digital systems of automatic regulation. Further development
of turbine engines is connected with application of qualitatively new materials (particularly composites), optimization
of the shape of compressor and turbine blades and technologies of their production. The paper discusses design
changes decreasing the destructive effects of foreign matter suction and indicates the possibility of increasing the maneuverability
of airplanes by thrust vectoring. Finally, development prospects of turbine propulsion are analyzed.

Analytical Study of General Insurance in India
Authors: Gupta Sumeet
Published: July 2021

There is a striking difference between developed and developing nations in terms of general insurance penetration and density. It was highest for United States in 2008. It was very closely followed by Switzerland. In fact, General insurance density and penetration both has always been high for these two countries. In this way, these two countries can be regarded as the world leader in general insurance industry. General insurance penetration has not shown much change over the years. For developed countries the average General insurance penetration for 2008 was 3.40 while that of developing nations was just 2.90. Also, there have been no major changes in these values since 2001.  Among developing countries, South Africa and Taiwan are fast gaining momentum. Russia is also a close competitor in terms of general insurance penetration. In the Indian sub-continent, it is Sri Lanka that has shown the maximum general insurance penetration and density. India is the next in the rank.

Authors: Gupta Sumeet , Sharma Rakesh Kumar
Published: July 2021

Oil & gas industry in India saw the light of the day when oil was struck at Makum near Marherita in Assam in the year 1967. Prior to independence the Oil & Gas industry in India had controlled by international companies. The entire domestic oil production was from one state â€“ Assam which stood at 250,000 tons per annum. This study provides a holistic examination of pricing and Taxation dynamics in Indiaâ€™s Petroleum sector. This study mainly highlights the issues related to current practices used by ONGC to determine the prices of crude oil, natural gas & value added products and also the various types of direct and indirect taxed imposed on and paid by the company. Moreover, this study also explain the process of price determination of crude oil , natural gas & value added products.
Theory of production in construction industry
Authors: Vivan André Luiz , Paliari José Carlos
Published: July 2021

In the absence of an explicit and specific theory, the management of production processes in construction is essentially based on a Taylorist view, based on the economic theory of production. Thus, given the particularities of construction, the plans developed are often unreal, with recurring delays and unforeseen circumstances during production. Thus, because of the importance and the latent need to develop a specific theory, this article uses a systematic literature review (SLR) to comprehend what has been developed and discuss the topic. The main objective is to answer the following research questions: 1) What is being proposed to develop a production theory applied to construction? 2) What is the approach used in the publications? 3) What can be proposed for the body of knowledge in question to fill gaps? Based on the results of the SLR, it was verified that the development of such a theory appears to be very incipient and not formalized in the publications, with inconclusive results and weak multidisciplinary cooperation. Furthermore, there are indications that authors associated with Lean Thinking may be leading research on production theory in construction since most of the publications have results that were conceptually based on Lean Construction principles. It is understood that the content of this article is relevant because it outlines the current stage of development of the theory and indicates possible paths to achievements.

Published: July 2021

Purpose Blunt cardiac injuries (BCI) have a wide clinical spectrum, ranging from asymptomatic myocardial contusion to cardiac rupture and death. BCIs rarely require surgical intervention, but can be rapidly fatal, requiring prompt evaluation and surgical treatment in some cases. The aim of this study was to identify potential factors associated with in-hospital mortality after surgery in patients with BCI. Methods The medical records of 15 patients who had undergone emergency cardiac surgery for BCI between January 2014 and August 2020 were retrospectively reviewed. We included trauma patients older than 18 years admitted to Regional Trauma Center, Gachon University Gil Medical Center during the study period. Clinical and laboratory variables were compared between survivors and non-survivors. Results Non-survivors showed a significantly higher Injury Severity Score (p=0.001) and Abbreviated Injury Scale in the chest region (p=0.001) than survivors. American Association for the Surgery of Trauma-Organ Injury Scale Grade V injuries were significantly more common in non-survivors than in survivors (p=0.031). Non-survivors had significantly more preoperative packed red blood cell (PRBC) transfusions (p=0.019) and were significantly more likely to experience preoperative cardiac arrest (p=0.001) than survivors. Initial pH (p=0.010), lactate (p=0.026), and base excess (BE; p=0.026) levels showed significant differences between the two groups. Conclusions Initial pH, lactate, BE, ventricular injury, the amount of preoperative PRBC transfusions, and preoperative cardiac arrest were potential predictors of in-hospital mortality.

Background. The main goal of root canal treatment is the prevention or treatment of apical periodontitis, which leads to the preservation of natural teeth. Traditionally, root canal treatment is carried out in a number of visits, using extra disinfecting agents in addition to irrigant used during cleaning and shaping procedures that primarily aim to reduce or eliminate microorganisms and their byproducts. from the root canal system before it is obtained. Recent advances in Endodontic technology, attracting dental experts and endodontists to perform root canal treatment in one visit. Numerous studies evaluate the effectiveness of single-versus multiple-appointment root canal treatment have been published, which reported no significant differences in effectiveness (healing rates) between these two treatment regimens.Purpose : preservation of the integrity of the molar teeth that have symptomatic complaints by taking proper care with a short visit time. Caset: A 21-year-old woman presents with concern in her lower left tooth, the patient tells that the tooth had been treated before at the dentist when she was a child. On clinical examination there is a composite restoration in occlusal tooth # 36, non vital teeth. On periapical radiology there are radiopaque on pulp chamber and a diffuse radiolucent area in the apical area of tooth # 36, then the diagnosis then determined Previously initiated therapy with asymptomatic apical periodontitis. Case Management : Tooth # 36 treated with one visit root canal treatment, Treatment is continued with fiber post installation and crown, patients no longer complain of pain after treatment. Teeth function normally again. Conclusion: One visit root canal treatment can successfully eliminate patient complaints and restore tooth function.
The Role of Propolis in Pulp Pain by Inhibiting Cyclooxygenase-2 Expression
Authors: Widjiastuti Ira , Saraswati Widya , Rahma Annisa
Published: July 2021

Background: Inflammation of the pulp can lead to elicit pain. Pain in inflammation is induced by the cyclooxygenase-2 enzyme (COX-2) which induces prostaglandin E2 (PGE2) resulting in pain. Pain in the pulp can be relieved by eugenol. In its application, eugenol is toxic to pulp fibroblasts. Due to the side effect, it is worth considering other biocompatible materials with minimal side effects, such as propolis. Flavonoids and phenolic acids that contained in propolis can inhibit COX-2. Therefore, an analysis outlined in the literature review is needed to examine the results of research related to the role of propolis as pulp pain relief by inhibiting COX-2 expression. Purpose: To analyze the role of propolis in pulp pain by inhibiting COX-2 expression. Reviews: Propolis extract that extracted by ethanol, water, and hydroalcohol has pain relief properties in the pulp by inhibiting COX-2 by directly binding to the COX-2 receptors and by reducing the production of proinflammatory cytokines which are COX-2 inducers, proven through in vivo, in vitro, and in silico studies in various target cell organs. Conclusion: Propolis extract has high prospect as inflammatory pain inhibitor in the pulp by inhibit COX-2 expression.
