Combined spectral and speech features for pig speech recognition
Authors: Wu Xuan , Zhou Silong , Chen Mingwei , Zhao Yihang , Wang Yifei , Zhao Xianmeng , Li Danyang , Pu Haibo
Published: December 2022

The sound of the pig is one of its important signs, which can reflect various states such as hunger, pain or emotional state, and directly indicates the growth and health status of the pig. Existing speech recognition methods usually start with spectral features. The use of spectrograms to achieve classification of different speech sounds, while working well, may not be the best approach for solving such tasks with single-dimensional feature input. Based on the above assumptions, in order to more accurately grasp the situation of pigs and take timely measures to ensure the health status of pigs, this paper proposes a pig sound classification method based on the dual role of signal spectrum and speech. Spectrograms can visualize information about the characteristics of the sound under different time periods. The audio data are introduced, and the spectrogram features of the model input as well as the audio time-domain features are complemented with each other and passed into a pre-designed parallel network structure. The network model with the best results and the classifier were selected for combination. An accuracy of 93.39% was achieved on the pig speech classification task, while the AUC also reached 0.99163, demonstrating the superiority of the method. This study contributes to the direction of computer vision and acoustics by recognizing the sound of pigs. In addition, a total of 4,000 pig sound datasets in four categories are established in this paper to provide a research basis for later research scholars.

Published: December 2022

This study evaluated factors that influence the cost-effectiveness of talazoparib, particularly for patients with a germline breast-cancer-gene-(brca)-mutation and locally advanced or metastasized breast cancer within the context of the German healthcare system. We constructed a partitioned survival model to compare medical costs and treatment effectiveness for patients with such cancers over 45 months. Transition probabilities were derived from survival data from a randomized Phase-III EMBRACA trial, utilities based on published reports, and costs in Euros, which included costs for drug acquisition, clinical monitoring, and treatment of adverse events. Willingness-to-pay thresholds were set to be multiples of the current German per capita gross domestic product. Treatment with talazoparib led to a gain of 0.32 life-years (0.22 quality-adjusted life-years). The mean total cost of €84,003 for talazoparib and €12,741 for standard therapy resulted in an incremental cost-effectiveness ratio of €223,246 per life-year and €323,932 per quality-adjusted life-year gained, indicating that talazoparib is unlikely to be cost-effective at current pricing.
Physician influence on medication adherence, evidence from a population-based cohort
Authors: Yao Shenzhen , Lix Lisa M. , Teare Gary , Evans Charity , Blackburn David F.
Published: December 2022

Background

The overall impact of physician prescribers on population-level adherence rates are unknown. We aimed to quantify the influence of general practitioner (GP) physician prescribers on the outcome of optimal statin medication adherence.

Methods

We conducted a retrospective cohort study using health administrative databases from Saskatchewan, Canada. Participants included physician prescribers and their patients beginning a new statin medication between January 1, 2012 and December 31, 2017. We grouped prescribers based on the prevalence of optimal adherence (i.e., proportion of days covered ≥ 80%) within their patient group. Also, we constructed multivariable logistic regression analyses on optimal statin adherence using two-level non-linear mixed-effects models containing patient and prescriber-level characteristics. An intraclass correlation coefficient was used to estimate the physician effect.

Results

We identified 1,562 GPs prescribing to 51,874 new statin users. The median percentage of optimal statin adherence across GPs was 52.4% (inter-quartile range: 35.7% to 65.5%). GP prescribers with the highest patient adherence (versus the lowest) had patients who were older (median age 61.0 vs 55.0, p<0.0001) and sicker (prior hospitalization 39.4% vs 16.4%, p<0.001). After accounting for patient-level factors, only 6.4% of the observed variance in optimal adherence between patients could be attributed to GP prescribers (p<0.001). The majority of GP prescriber influence (5.2% out of 6.4%) was attributed to the variance unexplained by patient and prescriber variables.

Interpretation

The overall impact of GP prescribers on statin adherence appears to be very limited. Even “high-performing” physicians face significant levels of sub-optimal adherence among their patients.

Published: December 2022

Pseudogymnoascus destructans is a fungal pathogen responsible for a deadly disease among North American bats known as white-nose syndrome (WNS). Since detection of WNS in the United States in 2006, its rapid spread and high mortality has challenged development of treatment and prevention methods, a significant objective for wildlife management agencies. In an effort to mitigate precipitous declines in bat populations due to WNS, we have developed and implemented a multi-year mitigation strategy at Black Diamond Tunnel (BDT), Georgia, singly known as one of the most substantial winter colony sites for tricolored bats (Perimyotis subflavus), with pre-WNS abundance exceeding 5000 individuals. Our mitigation approach involved in situ treatment of bats at the colony level through aerosol distribution of antifungal volatile organic compounds (VOCs) that demonstrated an in vitro ability to inhibit P. destructans conidia germination and mycelial growth through contact-independent exposure. The VOCs evaluated have been identified from microbes inhabiting naturally-occurring fungistatic soils and endophytic fungi. These VOCs are of low toxicity to mammals and have been observed to elicit antagonism of P. destructans at low gaseous concentrations. Cumulatively, our observations resolved no detrimental impact on bat behavior or health, yet indicated a potential for attenuation of WNS related declines at BDT and demonstrated the feasibility of this novel disease management approach.
Another man’s memories: Masculine trauma and Satanic Panic in The Believers (1987) and Angel Heart (1987)
Authors: Gough Charlotte
Published: December 2022

Focusing on The Believers (1987) and Angel Heart (1987), this article examines how occult crime is framed through the central male protagonists’ fragmented subjectivity in the respective investigation narratives. Through close analysis of the films’ shared cinematic languages of horror and neo-noir, I present how these texts are in direct dialogue with the ‘Satanic Panic’, the contemporary phenomenon of religious hysteria propagated by Reaganite conservatism and the New Christian Right. I argue that post-Vietnam masculine identity anxieties are intimately tied, and interrogated in these films, as part of a traumatic national history of white, patriarchal Satanic scapegoating and theocratic hegemony in the United States.
Entrepreneurship in non-Schumpeterian (or alternative) ways: Effectuation and Bricolage to overcome crises
Authors: Lima Edmilson de Oliveira
Published: November 2022

Objective: This essay aims to point out impediments to Schumpeterianism and the potential of the non-Schumpeterian ways regarding effectuation and bricolage to overcome crises. Methodology/approach: This is an essay based on the literature available mainly on effectuation and entrepreneurial bricolage as well as on empirical data from semi-structured interviews using qualitative methods. Main results: The text argues that the effectuation and bricolage approaches are particularly appropriate and useful for overcoming resource constraints, including their aggravation during crises. With the use of examples and a real empirical case, it constitutes a basis for further studies and dissemination of knowledge and can be useful as an inspiration for a more conscious, disseminated and perfected use of these non-Schumpeterian ways in entrepreneurship. Theoretical/methodological contributions: The study offers arguments, a theoretical framework with elements of a literature review and empirical data conducive to new promising research on effectuation and bricolage. Relevance/originality: The essay presents promising conceptual relationships and aspects of reality that are frequent and relevant, but not yet explored in national and international studies, in particular because it deals with effectuation and bricolage as ways of overcoming resource limitation and crises in lifestyle entrepreneurship (LE) and social entrepreneurship. Social/management contributions: Generation of greater awareness regarding the importance and need for research and use of entrepreneurial effectuation and bricolage, providing useful practices for doing a lot with little, overcoming resource limitations and overcoming crises.

Published: December 2022

Provision of quality early childhood education and care (ECEC) supports children’s learning with strong agreement that early childhood teachers (ECTs) are central to quality provision. In many countries, it is mandatory that ECEC services employ ECTs. However, Australian ECT employers report that early childhood graduates are not always well-prepared to work in ECEC settings. This may be because what constitutes optimal early childhood initial teacher education programs (EC ITE) is unclear. To investigate the design of EC ITE programs this research reports on (i) design of EC ITE programs across international contexts; and (ii) 19 Australian ECT employers’ perspectives on EC ITE program design. Findings indicate little consensus on the design of EC ITE programs, with inconsistencies across and within countries. Australian employers identified shortcomings in graduates knowledge. This research highlights recommendations to understand how programs prepare ECTs, by conducting research tracking preservice teachers from EC ITE programs into ECEC teaching.

The Effect of Water Depth on the Structure and Allocation of Waterlily (Nymphaea pubescens Willd) Biomass in Lebak Swampland in Kalimantan Selatan
Authors: ISMUHAJAROH Bakti Nur , INDRADEWA Didik , KURNIASIH Budiastuti , UTAMI Sri Nuryani Hidayah
Published: December 2022

Nymphaea pubescens is found in the swamplands of Kalimantan Selatan, where it lives in the shape of a basin with divergent levels of water. From February to June 2019, the environment and its development were studied in four zones, with depth differences ranging from 28 to 95 meters in the zone I, 28 to 99 meters in zone II, 54 to 112 meters in zone III, and 55 to 124 meters in zone IV. A transect system is used to zone the area, with fluctuating degrees of water depth reflected in each zone as one moves closer to a basin. Geomorphology in a basin has an essential relief, causing different levels of water surface depth in lebak swampland. The GPS was used to determine the distance traveled.

The purposive sampling technique determines the number of observation stations in each zone. In zone I, waterlily growth generated smaller and more frequent leaves than plants in zone II, which produced smaller and fewer leaves than plants in zone III, which produced smaller and fewer leaves than plants in zone IV. However, the area of the leaves expanded greatly with the depth of water, although the number of leaves fell dramatically with water depth. The organization of the percentage of biomass for the development of shoots and roots was different, even though the total biomass was not statistically different. Waterlily growing in shallower water depths had larger biomass allocations for seeds and lower biomass allocations for roots. Root biomass increased significantly as the depth of the water body increased.

This experiment showed that the deeper the water, the lesser the nutrients and the greater the extent the roots must spread to meet their nutritional requirements. Even though the relationship between leaf area and bloom number weakened as water depth increased, the relationship between leaf number and root number was significantly positive concerning biomass and water depth. Groundwater depth has a significant effect on the allocation of underground biomass (A), with the biomass proportion decreasing as water depth increases from 28 to 95 cm in zone I = 53.1 percent to 28–99 cm in zone II = 53.7 percent to 55–124 cm in zone III = 48.6 percent in zone IV = 42.4 percent. Because water depth has a considerable effect on the average aboveground biomass–to–underground biomass ratio, the average root crown ratio decreases as water depth increases. Among the lowest average ratios found are those found at a water depth of 55–124 cm in zone IV (ratio of 0.54 ± 0.2), while the highest average percentage found is that found at a water depth of 28–95 cm in the zone I (ratio of 1.25 ± 0.61).

Published: November 2022

A transformação digital está modificando a estrutura e o funcionamento da sociedade, inclusive as concepções de espaço e tempo, além dos modelos de negócios, estamos vivendo a transição de um mundo mais estável para um mundo mais dinâmico e complexo. Essa transformação exige, na perspectiva das carreiras profissionais, competências diferentes das quais eram demandadas em um passado recente. Logo, desenvolver competências transversais, aquelas que conseguimos transferir de um contexto para o outro ao longo da vida, coloca-se como um diferencial para atuar em um cenário em constante transformação. Diante do exposto, o objetivo deste artigo é avaliar o desenvolvimento de competências transversais de estudantes após utilizarem um modelo de aprendizagem que articula a metodologia de aprendizagem baseada em desafios com a abordagem do design thinking de modo a aproveitar a complementaridade de uma abordagem mais técnica com uma abordagem mais social, promovendo assim um processo mais integral. Esse modelo foi aplicado em uma turma de estudantes de engenharia mecânica e, como resultado, observou-se, segundo a percepção dos estudantes, que o desenvolvimento de todas as competências transversais, que compõem o modelo de aprendizagem, foi muito bem avaliado. Ainda, a correlação positiva entre as práticas de aprendizagem e o desenvolvimento de competências transversais, demostra que o modelo de aprendizagem proposto contribui, de maneira significativa, para estimular os estudantes no processo de aprendizagem potencializando o desenvolvimento de competências transversais.

Synthesis of National Research on School Climate in Czech Republic
Authors: Kachnic Filip , Cohen Jonathan
Published: November 2022

Educators have been attuned to the importance of school climate for more than 100 years (Cohen,  McCabe, Michelli,  & Pickeral, 2009). School climate is an ecologically informed idea that recognizes individual, small and large group trends about a range of safety, relationships, teaching & learning and environmental issues that shape student learning and their development. School climate is measurable. Over the last three decades, school climate has become a growing focus for educational practice and policy leaders around the world (Ruiz et al, 2021; Cohen & Espelage, 2020; Thapa et al, 2013). As a result, we suggest that school climate and school-climate informed improvement efforts need to be studied on national levels (Vicente et al, 2021). Berkowitz's recent national-level study on positive school climate and its relationship to socioeconomic status and achievement of Arabic speaking students in Israel (Berkowitz, 2017 & 2020), has proved to be highly relevant bringing solutions to global issues (Bradshaw, et al. 2021). Our scoping review was conducted to advocate for the importance of school climate and for its role to inform national policy. It took place in the Czech Pedagogical Bibliographic Database of the J. A. Komenský Pedagogical Library in June 2020. The reasons for choosing this database were its terminologically unified annotation of bibliographic records using the Czech Pedagogical Thesaurus and its intentional scope to cover pedagogical literature (Email communication, Petišková, May 6th, 2020; Petrovičová, 2012). In the first step, we searched by the keyword "school climate" (in Czech) and identified a total of 383 bibliographic records. Using a programming script created for the purpose of our study by a university librarian, we identified a total of 2550 keyword combinations with the keyword "school climate." The keyword "school climate" was most often associated with the keyword "primary school" (N = 113). The second most frequent combination was "school climate" and "school environment" (N = 103). The third most numerous combination was "school climate" and "interpersonal relationships" (N = 92). The fourth most numerous combination was "school climate" and "teacher-student relationship" (N = 92). School climate is being studied in the Czech Republic on the primary and lower secondary school level, as well as in relational contexts.

O presente artigo originou-se a partir da pesquisa com trabalhadores idosos, realizada em municípios da Serra Gaúcha - RS. O objetivo principal deste trabalho é analisar a percepção de trabalhadores idosos com relação ao seu processo de aprendizagem no trabalho. Para tal, foram entrevistados 20 trabalhadores idosos, de ambos os sexos, empregados no mercado formal. Foram realizadas entrevistas semiestruturadas e, por meio da técnica de tratamento de dados Análise de Conteúdo, foram estabelecidas duas categorias à posteriori: aprendizagem e tecnologia digital. Os resultados apresentados e discutidos por meio da articulação entre olhares teóricos e as falas dos entrevistados, consideraram aspectos do funcionamento cerebral, aprendizagem, tecnologia digital e mundo do trabalho. A partir desta investigação, é possível perceber que a aprendizagem ocorre durante todo o ciclo vital e que, na velhice, é preciso haver oportunidades para que a pessoa idosa se mantenha ativa e saudável em seu local de trabalho. A inclusão digital mostra-se como uma estratégia para que o idoso sinta-se desafiado e estimulado no ambiente laboral. Assim como o trabalho, a tecnologia digital, além de fonte de estímulo cognitivo, é uma forma de ampliação da autonomia, e que traz bem-estar e qualidade de vida nesta fase do desenvolvimento humano.

Estamos na era da globalização social, económica e tecnológica onde não existem fronteiras (ou parecem não existir). Vive-se um tempo de incertezas, mas também um tempo de oportunidades. No nosso espaço social evidencia-se a diversidade humana, que tem tanto de interessante como de ameaçador. Há que aprender a viver juntos. Neste contexto de interações sociais ocorrem situações dilemáticas e conflituosas, que a escola tem de ajudar a solucionar. Para darem uma resposta eficaz aos desafios da sociedade atual, diversa e dinâmica, os professores procuram atualizar os seus conhecimentos e competências, fazendo formação de forma continua, nomeadamente, na área da mediação de conflitos. Tendo por base esta problemática formulou-se para este estudo a seguinte questão de partida: De que modo a formação em mediação de conflitos contribui para o melhor desempenho docente na educação para a convivência? Para dar resposta a esta questão propôs-se o seguinte objetivo geral: compreender as razões dos professores em fazer formação contínua em mediação de conflitos e como este avaliam essa formação. A pesquisa realizada seguiu a abordagem metodológica qualitativa, com recurso à entrevista semiestruturada para a recolha de dados e à técnica de análise de conteúdo para analisar os mesmos. Os resultados obtidos apontaram que os professores decidem fazer esta formação porque a escola mudou e enfrentam problemas disciplinares. Consideraram a formação continua, importante e útil para a atualização de conhecimentos e de estratégias, que contribuam para um melhor desempenho profissional e, simultaneamente, para a qualidade do processo educativo.

Published: November 2022

O presente artigo apresenta parte dos resultados de uma investigação que teve como objetivo analisar as contribuições da Ficção Científica para a Educação CTS (Ciência, Tecnologia e Sociedade) no contexto da formação inicial de professores de Ciências e Biologia. A pesquisa, de natureza qualitativa, consistiu em uma pesquisa intervenção cujos dados foram produzidos em aulas de uma disciplina eletiva do curso de Ciências Biológicas de uma universidade pública fluminense. Nos trabalhos de conclusão da disciplina, os estudantes elaboraram sequências didáticas com enfoque CTS que deveriam utilizar séries de TV à escolha de cada grupo. Neste trabalho trazemos as análises de três séries de TV (“The Flash”, “Orphan Black” e “The Rain”) a partir das categorias dos elementos contrafactuais e dos polos temáticos elaborados por Piassi (2007). Os resultados mostram que as obras contribuem para a Educação CTS de formas distintas, o que indica a versatilidade do gênero e suas potencialidades como recurso didático no ensino de Ciências. As discussões que podem ser contempladas em sala de aula a partir das séries englobam aspectos sociais diversos, questões políticas e relações humanas, tangenciadas por temas científicos e tecnológicos.
Interligando Conceitos sobre Saúde no Ensino de Biologia Celular
Authors: Michelotti Angela , da Silva Loreto Elgion Lucio
Published: November 2022

De acordo com a Base Nacional Comum Curricular, o ensino sobre “células” no ensino fundamental II aborda principalmente os tipos celulares e organelas citoplasmáticas. Na maioria das vezes, estas estruturas são apresentadas de forma teórica, com o uso de livros didáticos, mas sem contextualização de como estas estruturas microscópicas, estão intimamente associadas ao nosso cotidiano. O presente trabalho tem como objetivo buscar quais as concepções os alunos de 8º e 9º ano do ensino fundamental II trazem sobre conceitos relacionados à biologia celular, como os envolvendo a história da ciência, diferenciação celular, microrganismos, multiplicação celular e cicatrização. Estes conceitos são importantes para compreender a organização e funcionamento do corpo humano e, portanto, fundamentais para uma efetiva alfabetização cientifica. A pesquisa foi realizada com 114 alunos, de turmas de 8º e 9º ano, de duas escolas públicas.  Um “questionário em três camadas” foi aplicado, onde a primeira camada é uma questão de múltipla escola, com três alternativas, sendo uma opção correta e duas erradas. Na segunda camada, o aluno deve escolher a opção que melhor completa (explica/justifica) a alternativa escolhida na primeira parte, e contém três alternativas, sendo uma certa e duas erradas. Já a terceira parte é o nível de confiança ao responder as questões acima, se o respondente tem certeza de sua resposta na primeira e segunda camada ou não. Percebe-se que os alunos compreendem que os animais e as plantas são constituídos por células, e estes compõem os tecidos e órgãos. Os educandos apresentaram pouco conhecimento em relação a história da ciência, não identificando quem visualizou as primeiras células, tão pouco conseguem interligar que os microrganismos apresentam benefícios, demonstrando apenas o aspecto nocivo para o corpo humano.  Ao apresentarmos aos alunos os tipos celulares eles apresentaram dificuldades em identificar as células eucarióticas e procarióticas. Aos serem questionados sobre a relação entre o corpo humano e os microrganismos, o processo de cicatrização e multiplicação celular, e o processo inflamatório, percebe-se um decréscimo em seus acertos, pois nessas questões envolviam contextualização e a necessidade de interligar dois ou mais conceitos para responder. Os documentos norteadores vigentes trazem conteúdos teóricos e abstratos e que não são contextualização com fatos do cotidiano dos alunos.

Published: November 2022

É consenso que os jogos digitais extrapolam os limites do entretenimento, mostrando-se como potentes instrumentos para o ensino e aprendizagem nos diversos campos de conhecimento. No que se refere a Educação Especial, muitas lacunas são evidenciadas desde que o discurso da Inclusão Escolar passou a ser disseminado na realidade das escolas comuns, lacunas essas que possibilitam a inserção dos jogos digitais como aliados para ampliar as possibilidades de alcance de um contexto verdadeiramente inclusivo nas instituições de ensino e na sociedade como um todo. Nesse contexto, esse trabalho teve como objetivo realizar uma revisão sistemática da literatura para traçar um panorama dos artigos científicos que apresentam jogos sérios os quais tratam de questões relativas à Educação Especial e seu público. O propósito foi compreender as abordagens que têm sido utilizadas acerca dos jogos sérios para o campo da Educação Especial de modo a conhecer as possíveis contribuições desses jogos para o público de estudantes com deficiências. O Portal de Periódicos Capes foi a fonte de dados utilizada e, após o processo de buscas e seleção, foram analisados 16 artigos científicos que contemplavam os critérios estabelecidos. Os resultados reportam jogos cujo enfoque se fundamenta nas especificidades advindas da condição de deficiências, além de evidenciar a importância do trabalho entre especialistas de jogos e da Educação Especial e a participação ativa dos usuários alvo durante o planejamento e construção dos jogos. O campo da Educação Especial mostra-se promissor e fértil para o desenvolvimento de jogos digitais e espera-se que essa revisão indique caminhos para viabilizar o desenvolvimento de jogos considerando as demandas que esse campo de conhecimento apresenta.

Este artigo é um recorte de uma investigação mais ampla desenvolvida em um curso de mestrado. Neste texto, temos por objetivo apresentar e discutir resultados de uma revisão sistemática de literatura que analisa estudos que tratem da Alfabetização Científica (AC) em articulação com as Tecnologias Digitais de Informação e Comunicação (TDIC) no Ensino de Ciências. O lapso temporal compreendeu os anos de 2014 a 2018 e foram consultadas quatro bases de dados, sendo duas nacionais e duas internacionais. Esta revisão justifica-se pela atual e necessária discussão sobre a alfabetização científica no contexto da cultura digital que perpassa as relações sociais e educacionais contemporâneas. Nesse sentido, o uso das TDIC como recursos de suporte ao desenvolvimento da AC torna-se também tema relevante. Como resultados, a revisão aponta para uma lacuna a ser preenchida tendo em vista a pequena quantidade de trabalhos que enfocam com clareza essa relação e o fato de que, quando essa abordagem ocorre, os estudos apresentam uma perspectiva mais utilitarista das tecnologias, sem a exploração de suas potencialidades de forma articulada com a AC. Outro ponto que merece destaque é o fato de que muitos estudos trazem como substrato das discussões a articulação teórico-metodológica entre a alfabetização científica e os enfoques CTS e CTSA.
The effect of ecologically based playgrounds on the child's sensory and motor functions
Authors: Özdemir Ayşem Ecem , Kanbur Bahar Nur
Published: November 2022

Children actively learn themselves, their immediate environment and the world through play. It is observed that the environment plays a major role in increasing the physical activity levels of children and ensuring their functional development.
Being intertwined with nature is very important for children in environmental education. However, the importance of physical planning of ecological playgrounds for children is often overlooked. It is known that natural spaces designed within the framework of ecological principles and containing different habitat types (water, soil, plants, animals, etc.) are more suitable for environmental education than classical green spaces, especially for children living in cities. It is known that a flexible and changeable environment provides more opportunities for positive behavior in environmental education. In addition to the positive aspects that the natural elements in the environment contribute to the psychological, emotional and social integration of the child, there are also contributions in terms of motor and sensory development. In addition, the areas designed in this direction reveal the feeling of freedom of children and are effective in making them more sensitive to environmental issues.

The Semarang and Tegal coastal waters are traditional fishing ground areas. However, the increasing use of coastal areas for various activities will increase pollutants in the coastal waters.  Heavy metals are pollutants that always appear in waters and accumulate in marine organisms. These study aims to determine As and Hg metals contained in the tissues of several marine organisms caught on the coast of Semarang and Tegal, Central Java. The analysis of As and Hg concentrations in organismal tissues using ICPMS.  The results showed that As and Hg were found in biota such as white shrimp (P. merguensis), blue crab (P. pelagicus), shellfish (A. inaequivalvis) and gastropods (H. ternatanus). Arsenic concentrations in the four biotas caught in Tegal (1.6 – 5.3 ppm) and Semarang (2.58 – 4.9 ppm). Meanwhile, Hg metal (0.02 – 0.15 ppm) in Tegal and (0.034 – 0.15 ppm) in Semarang.  The concentration level of As based on the biota caught in the Tegal waters are sequentially Shellfish > White shrimp > Gastropods > Blue swimming crab.  Meanwhile, the concentration of Arsenic in the biotas in Semarang waters are sequentially shellfish > white shrimp > blue crab > gastropods. However, Hg metal in the biota obtained in these two areas is very low  Pesisir Semarang dan Tegal merupakan daerah penangkapan perikanan tradisional.  Namun dengan semakin meningkatnya pemamnfaatan wilayah pesisir untuk berbagai kegiatan akan meningkatkan polutan dalam perairan.  Logam berat merupakan polutan yang selalu muncul dalam perairan dan terakumulasi organisme laut.  Penelitian ini bertujuan untuk mengetahui logam As dan Hg yang terdapat dalam jaringan beberapa biota yang ditangkap pesisir Semarang dan Tegal Jawa Tengah.  Analisa konsentrasi As dan Hg dalam jaringan organisme menguunakan ICPMS.  Hasil penelitian menunjukan logam As dan Hg ditemukan dalam biota seperti udang putih (P. Merguensis), rajungan (P. pelagicus), kerang bulu (A. inaequivalvis) dan gastropoda (H. ternatanus).  Konsentrasi Arsen di keempat biota yang ditangkap di Tegal (1,6 – 5,3 ppm) dan Semarang (2,58 – 4,9 ppm).  Sedangkan logam Hg (0,02 – 0,15 ppm) di Tegal dan (0,034 – 0,15 ppm) Semarang.  Tingkat konsentrasi logam As berdasarkan biota yang tertangkap di perairan Tegal secara berurutan Kerang bulu > Udang putih > Gastropoda > Rajungan.  Sedangkan konsentrasi Arsen dalam biota di perairan Semarang secara berurutan Kerang bulu > Udang putih > Rajungan > Gastropoda.  Namun logam Hg dalam biota yang didapat di kedua daerah tersebut sangat rendah.

The urge to remanufacture and address environmental concerns in various industrial processes has drawn the attention of academics as well as practitioners towards Closed-loop Supply Chain Networks (CLSC). Although everchanging and complex external factors including social and economic ones, adversely impact the sustainable development of closed-loop supply chain networks. The basic aim of the research is to optimize the functioning of CLSC networks. For the above-said, two objective functions are made. The first objective is to minimize the cost of production and assembly expenses of the forward and reverse logistics. Secondly, an endeavour has been made to reduce the fixed costs associated with plants and retailers. For the sake of achieving two objective functions, two methods are employed: triangular fuzzy numbers and triangular intuitionistic fuzzy numbers. Among the two methods, triangular intuitionistic fuzzy numbers achieved the said objectives with greater optimization substantiated by statistics. This method can deal with uncertain external factors without undermining the optimization of the CLSC networks.

This paper describes the Networked Energy Systems Emulation Center – DLR-NESTEC – a platform for research on power grids of the future. The DLR-NESTEC consists of a large number of networked power electronic components with which real hardware can be emulated using a real-time simulation system. The grid networking is realized via cable emulators. The laboratory works with real physical power flows and has a connected load of 800 kVA. In addition to the emulators, real network components can be integrated into the laboratory. The sector coupling is addressed by the coupling of charging infrastructure of electric cars as well as the integration of electricity-controlled heating systems. In addition, hydrogen technologies can be integrated. The laboratory is controlled by a SCADA system coupled to high-resolution measurement equipment. With the help of DLR-NESTEC, various future questions regarding robust and safe operation sector-coupled energy networks can be addressed – for instance the operation of a grid structure with a high share of controllable loads without a superordinate control.
Central role of laboratory medicine in public health and patient care

Published: November 2022

Clinical laboratories play a vital role in the healthcare system. Objective medical data provided by clinical laboratories supports approximately 60–70% of clinical decisions, however, evidence supporting this claim is poorly documented and laboratories still lack visibility, despite their indisputable impact on patient care and public health. The International Federation for Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Outcome Studies in Laboratory Medicine (TF-OSLM) was recently developed to support directed research evaluating the role of laboratory medicine on clinical outcomes. Establishing and documenting this evidence is key to enhance visibility of the field in the eye of the public and other healthcare professionals together with optimizing patient outcomes and health care system operations. In this review, we discuss four areas that exemplify the contribution of laboratory medicine directly to patient care. This includes high-sensitivity cardiac troponin (hs-cTn) and N-terminal pro-B-type natriuretic peptide/B-type natriuretic peptides (NT-proBNP/BNP) for the diagnosis and prognosis of myocardial infarction and heart failure, respectively, and procalcitonin for the management of sepsis and antibiotic stewardship. Emerging markers of traumatic brain injury and the role of laboratory medicine in the fight against the COVID-19 pandemic are discussed along with an introduction to plans of IFCC TF-OSLM.

Published: November 2022

We derive a generalized Pohozhaev’s identity for radial solutions of p-Laplace equations, by using the approach in [P. Korman,
Global Solution Curves for Semilinear Elliptic Equations,
World Scientific Publishing, Hackensack, 2012], thus extending the work [H. Brézis and L. Nirenberg,
Positive solutions of nonlinear elliptic equations involving critical Sobolev exponents,
Comm. Pure Appl. Math. 36 1983, 4, 437–477], where this identity was implicitly used for the Laplace equation.
