The ability of a bank to run its operations effectively is to determine its finances. This paper takes the topic of BUMD banking research, especially BPR in 2016-2020. The purpose of this study was to determine the effect of Non Performing Loans (NPL) and solvency on the financial performance of BPD in Indonesia. In this study, we used a population of BPRs registered with BUMD and used a sampling technique, namely purposive sampling with samples from BPR Yogyakarta and BPR BPR Magelang to analyze the data in this study, multiple linear regression was used to analyze the relationship between various factors and the desired outcome. Solvency is proxied by debt to asset ratio (DAR) and debt to equity ratio (DER), while credit risk is proxied by non-performing loan (NPL). For financial performance, Return on Assets (ROA) is a proxy for financial performance. The results of the analysis show that solvency is proxied by the ratio of debt to assets (DAR) and the ratio of debt to equity (DER) has an effect on financial performance and credit risk has an effect on financial performance.

Published: December 2022

A veszélyesáru-szállítás szigorú, nemzetközi szabályokhoz kötött. A veszélyes áru közúti szállításának szigorú szabályozása több szempontból is kiemelt jelentőségű, mivel egy esetleges közúti baleset során a veszélyes anyag szabadba kerülésével jelentős méretű veszélyeztetett terület alakulhat ki. Másrészt a veszélyes áru tulajdonságait kihasználva, a lakott területeken áthaladó veszélyesáru-szállítmány potenciális célpontja lehet egy esetleges terrorcselekménynek. Az ilyen típusú kockázat csökkentésére a veszélyesáru-szállítási szabályzatokban külön rendelkezések vonatkoznak, azonban előfordulhat, hogy ezeket az intézkedéseket a szűkebb gazdasági, társadalmi és biztonsági környezet sajátosságaihoz érdemes igazítani. A publikációban a szerzők küldeménydarabban való szállítás esetén a visszaélés elleni rendelkezések hatálya alól mentesülő, propán-bután gázszállítmány elleni szándékos cselekmény következményeit vizsgálják meg szoftveres kockázatelemzés segítségével.

Published: December 2022

O presente estudo tem como objetivo analisar as representações sociais (RS) da depressão infantil. Trata-se de um estudo quanti-qualitativo, ancorado ao aporte teórico da Teoria das Representações Sociais (RS). Participaram do estudo 120 crianças, com idades entre 8 e 12 anos (M = 2,0; DP = 0,47), da cidade de Campina Grande-PB, no contexto escolar e que maioritariamente habita com seus pais (83,3%). Os dados foram advindos da Técnica de Associação Livre de Palavras (TALP) em face aos estímulos; depressão, pessoa deprimida e eu mesmo. Esses estímulos foram processados pelo software Tri-Deux-Mots e analisados por meio de uma Análise Fatorial de Correspondência (AFC). Os resultados demonstram que a depressão, pessoa deprimida e a autopercepção das crianças acerca da depressão são representadas de forma multifacetada a partir das diferentes ancoragens. Especificamente, verifica-se que as representações dos atores sociais acerca da depressão encontra-se ancoradas nos sentimentos de fragilidade, suicidio, desanimo, o que corrobora para um conhecimento elaborado e compartilhado socialmente. Os dados dessa pesquisa apontam para a construção do conhecimento prático acerca das representações sociais da depressão infantil contribuindo para elaboração de intervenções e ações, assim como, na prevenção de futuros casos de depressão no contexto escolar.
Pessoas com deficiência e o mercado de trabalho – Revisão da literatura
Authors: Santos Samara Fernandes dos , Souza Daniel Cerdeira de 
Published: December 2022

Compreendemos a pessoa com deficiência como aquela que tem impedimentos de longo prazo de natureza física, mental, intelectual ou sensorial, o qual, em interação com diversas barreiras sociais, podem ter sua participação plena e efetiva na sociedade dificultada ou impedida. O objetivo deste estudo foi analisar a literatura sobre a experiência de pessoas com deficiência (PcD) no mercado de trabalho. Trata-se de uma revisão integrativa da literatura, onde analisamos, pelo procedimento de Análise de Conteúdo, 28 artigos colhidos no Portal Periódicos Capes. Os dados possibilitaram a construção de cinco categorias: 1) Garantia do direito de acesso ao mercado de trabalho; 2) Contratação de pessoas com deficiência; 3) Barreiras de acesso e permanência no mercado de trabalho; 4) Desenvolvimento do trabalhador com deficiência; 5) Rompendo as barreiras, que discutem que ainda há um longo caminho a percorrer para a efetiva inclusão de PcD no mercado de trabalho, de modo que o que ocorre é uma contratação compulsória para que as organizações não sofram sanções do Ministério Público. Ainda foi observado que muitas organizações vendem a percepção de serem inclusivas e apenas usam a imagem das PcD para ganhar visibilidade. Por fim, a verdadeira inclusão requer a transformação dos espaços de trabalho em espaços de justiça social e cuidado, fugindo da perspectiva de “readequação” do espaço físico para inclusão e indo de encontro à valorização da potência da diversidade.
FeS/FeS2 nanoscale structures synthesized in one step from Fe(ll) dithiocarbamate complexes as a single source precursor
Authors: Agoro Mojeed A. , Meyer Edson L. 
Published: December 2022

Nanoscale FeS and FeS2 mixed phases were synthesized by one-pot decomposition of (N-anil-N-piperldtc)Fe1 as FeS#1), (N-piperldtc)Fe2 as FeS#2) and (N-anildtc)Fe3 as FeS#3) complexes as precursors, with the help of tri-n-octylphosphine oxide (TOPO) coordinating solvent. Their morphology, stability, size, optical and structural characteristics were observed using various material characterization instruments. In comparison to the FeS#2 nano-flower shape, FeS#1 and FeS#3 have a uniform nano-rod shape. A one-step decomposition pattern was obtained from the thermal gravimetric analysis (TGA) results with 3% final mass residual. The high-resolution transmission electron microscopy (HRTEM) image reveals an aggregation and size diameter of around 14.47–30.25 nm for the three samples. The optical response between 3.8 and 4.2 eV from the three samples shows that they are inconsiderable materials for solar cells application. The diffraction peaks for the three samples matched well with the FeS/FeS2. These nanoscale materials can be used in a variety of applications, including lithium-ion batteries, biosensors, hydrogen evolution, and multifunctional nanocomposite materials.
Persistence of Mycobacterium tuberculosis in response to infection burden and host-induced stressors
Authors: Parbhoo Trisha , Schurz Haiko , Mouton Jacoba M. , Sampson Samantha L. 
Published: December 2022

IntroductionAs infection with Mycobacterium tuberculosis progresses, the bacilli experience various degrees of host stressors in the macrophage phagosome such as low pH, nutrient deprivation, or exposure to toxic agents, which promotes cell-to-cell phenotypic variation. This includes a physiologically viable but non- or slowly replicating persister subpopulation, which is characterised by a loss of growth on solid media, while remaining metabolically active. Persisters additionally evade the host immune response and macrophage antimicrobial processes by adapting their metabolic pathways to maintain survival and persistence in the host.MethodsA flow cytometry-based dual-fluorescent replication reporter assay, termed fluorescence dilution, provided a culture-independent method to characterize the single-cell replication dynamics of M. tuberculosis persisters following macrophage infection. Fluorescence dilution in combination with reference counting beads and a metabolic esterase reactive probe, calcein violet AM, provided an effective approach to enumerate and characterize the phenotypic heterogeneity within M. tuberculosis following macrophage infection.ResultsPersister formation appeared dependent on the initial infection burden and intracellular bacterial burden. However, inhibition of phagocytosis by cytochalasin D treatment resulted in a significantly higher median percentage of persisters compared to inhibition of phagosome acidification by bafilomycin A1 treatment.DiscussionOur results suggest that different host factors differentially impact the intracellular bacterial burden, adaptive mechanisms and entry into persistence in macrophages.

ObjectiveThe aim of this study was to explore the different predictive values of depression among patients with different cardiac systolic function levels.MethodsFour hundred eighty-three consecutive patients with obstructive coronary artery disease (CAD) were included the depressive state was assessed using the Chinese version of the Patient Health Questionnaire 9 (PHQ-9). Depression was defined as have depressive symptoms with a PHQ-9 score ≥5. The level of cardiac systolic function was classified as left ventricular ejection fraction (LVEF) ≥50 and &lt;50%.ResultsOver a median of 26.2 months, 421 patients completed the follow-up and experienced 101 major adverse cardiovascular events (MACEs), 45 non-cardiac rehospitalizations, and 17 deaths. Predictors for clinical outcomes in patients with different cardiac systolic function levels were not the same. For participants with preserved LVEF, depression was associated with increased risks for cardiovascular events and composite outcomes. However, when focusing the whole population, predictive values of depression for MACEs, non-cardiac rehospitalizations, and composite endpoints all dropped. Receiver operating characteristic (ROC) analyses further confirmed that depression was the one of the main predictors for all clinical outcomes. With the combination of other simple features, area under curve (AUC) could reach 0.64–0.67.ConclusionsInconsistent with the general impression, depression is found to have a closer linkage with clinical outcomes in CAD patients with preserved LVEF rather than in those with decreased LVEF. These findings appeal for more attention on CAD patients with depressive symptoms and comparatively normal LVEF. Including psychological factors may be a good attempt when constructing risk prediction models.
