Authors: Longard Lukas , Wang Yuxi , Herz Oliver , Metternich Joachim
Published: May 2024

KPI systems for evaluating and improving industrial processes are often used ineffectively in production companies, mostly due to arbitrarily selected KPIs and an overemphasis on financial aspects. Existing performance management approaches only describe basic elements and offer few practical recommendations. Implementation is usually only carried out by upper and middle management and neglects integration into production. This article presents a methodology that derives KPIs from corporate objectives in order to identify precise deviations and support data-driven analyses. The method is illustrated by evaluating the example of a process-accurate recording of throughput time.
El género gramatical en español: historia de un concepto
Authors: Montero Curiel Pilar
Published: May 2024

El objetivo de este trabajo es analizar la evolución del concepto género gramatical en español desde una perspectiva lexicográfica. Partiendo de la idea de que el género en español ayuda a expresar relaciones de concordancia con determinantes y otras clases de palabras que acompañan al sustantivo en el grupo nominal, trataremos de comprender cómo se produjo el paso del vocablo latino GENUS, GENERIS al castellano género, en una trasposición conceptual que, para explicar el vocablo desde el punto de vista semántico, ha tenido siempre en cuenta sus relaciones con el concepto sexo (biológico). Esta visión aflora en los primeros diccionarios de la lengua que conceden al género una especialización gramatical de uso y llegan hasta la última edición del repertorio académico, la 23.ª, de 2014. Mediante el análisis de las definiciones que ofrecen los diccionarios del español, y con el apoyo de algunas de sus gramáticas, se intentará demostrar que el uso del sustantivo género con sentido gramatical es tardío en los glosarios de nuestra lengua y que, desde los primeros registros, no logró desprenderse de sus primitivas acepciones, más próximas a los conceptos ‘clase’, ‘tipo’, ‘especie’, ‘categoría’ (habituales desde Nebrija) de los que también derivó el que nos ocupa. Porque, como muestran los diccionarios, esta acepción surgió para clasificar la categoría del nombre según el sexo del referente o para establecer relaciones sintácticas de concordancia con otras clases de palabras, sin olvidar su carácter morfemático en sustantivos que designan especies con función procreadora.

Authors: Kolupaev B.B. , Kolupaev B.S. , Levchuk V.V.
Published: May 2024

The Maxwellian relaxation and internal friction of a mixture of amorphous polymers: polyvinyl butyral (PVB) - polyvinyl chloride (PVC) are studied. It has been found that by changing the temperature (T) and content (j ) of the ingredients, it is possible to control the value of viscoelastic moduli, viscosity, damping force, and energy dissipation due to Maxwellian relaxation caused by the action of ultrasonic vibrations with a frequency (w ) of 0.4 MHz on the composite. The use of computational methods, models, and a phenomenological approach made it possible to differentiate the effects of relaxation and indicate the ways to optimally combine the desired properties of the components in the system.

Published: May 2024

The disposal of agricultural waste ash is a great ecological challenge. This study analyzed the basic properties of corn straw ash and soybean straw ash, encompassing the identification of key oxides, the assessment of particle size distribution, and the performance of thermogravimetric analysis. This study also evaluated the potential of corn straw ash and soybean straw ash to replace cement in mortar and concrete through laboratory tests. The findings indicated that the strength activity index of corn straw ash was higher than soybean straw ash. Furthermore, when these ashes were used as cement replacements, the compressive strength of concrete decreased. Notably, concrete containing corn straw ash exhibited greater strength than concrete with the same substitution amount of soybean straw ash. Specifically, at a 5% substitution level, the compressive strengths of corn straw ash concrete and soybean straw ash concrete were 31.5 and 30.5 MPa, respectively. Additionally, soybean straw ash concrete demonstrated superior resistance to water penetration compared to corn straw ash concrete. Both corn straw ash and soybean straw ash exhibited the potential to enhance the early crack resistance of concrete.

Published: May 2024

Corona virus (COVID-19) is the reason behind the collapse of the National Assembly. The first is the Final Semester Assessment (FSA) , which is a component of the student's graduation. The aforementioned evaluation process is a crucial consideration for the teacher since it uses several intricate surveys and mark components. A prediction model is employed to assist teachers in providing suitable results for student learning. The method that is used is called the multiple linear regression. This multiple linear regression algorithm yields an accuracy level of approximately 92%. The analysis results using the method are used as a guide to understanding student’s index. This index is a rating that appears based on the Minimum Credit Count (MCC). Therefore, the goal of this study is to determine students' understanding of the FSA prediction value, which will be taken into consideration through the results of the MCC weights in the form of a range in the form of "Grade." Additionally, the research aims to determine the accuracy of the results from the model obtained using multiple linear regression algorithms in predicting students' FSA.

Authors: Fernandes Caromano Caroline , Kaki Walid Dani , Van Andel Tinde , Kockelkorn Max
Published: May 2024

A cotton headdress ornamented with several botanical and faunal elements (TM-5074-2) is kept in the depot of the Wereldmuseum in Amsterdam. There is little information about the provenance of the object or its context of use. Identified by the museum as a ‘shaman hood’, is said to have been obtained from an Asháninka indigenous community along the Ene River, Peruvian Amazon. The unusual composition of the hood, with 16 bundles of bird fragments, 39 bundles of mammal parts, and 3332 seeds, raises several questions. Is the object a traditional Asháninka ornament? Is the combination of so many distinct elements a result of later additions? Is it possible that the hood was manufactured for sale? In addition to literature research, the identification of the biological material can offer some clues if the object was manufactured in the same region inhabited by the Asháninka communities. Through the morphological comparison of the plant and animal parts attached to the hood with the botanical and zoological collections of the Naturalis Biodiversity Center, this study aimed to provide new tools for provenance research, by identifying the species present in the object. As a result, eight different plant species, eight bird taxa and at least eight mammal taxa attached to the object were identified, most of them native to the Peruvian Amazon. Finally, with the identification of the species, we proposed possible interpretations for the selection of plants and animals added to the shaman hood based on the historical context and the Asháninka worldview.

Published: May 2024

To evaluate the intratubular penetration depth of ultrasound-activated bioceramic sealant cements into root dentin, specifically at the dentin-cement interface. This in vitro experimental study was conducted with samples that were randomly divided based on the type of sealer used and whether ultrasound activation was applied prior to obturation. This resulted in four experimental groups (n=40). Groups A1 and B1 utilized the Eighteeth Ultra X ultrasonic activator with a blue tip #20 featuring a 2% taper at low power for activation, while groups A2 and B2 did not employ any form of activation. The symbol (+) denotes groups with ultrasonic activation, while (-) represents groups without ultrasonic activation. In the middle third, it was observed that BioC Sealer (+) had a mean sealing value of 0.66±0.17, while MTA Fillapex (+) showed a mean value of 0.38±0.07.  It was found that BioC Sealer (-) had a mean sealing value of 0.24±0.04 in the middle third, while MTA Fillapex (-) showed a mean value of 0.16±0.04. These differences were not statistically significant (p=0.569). In the apical third, the BioC Sealer (-) presented a mean sealing value of 0.44±0.17, while the MTA Fillapex (-) obtained a mean value of 0.30±0.04. However, this difference did not reach statistical significance (p=0.0745), suggesting that both materials can provide a similar seal in the apical third. The results suggest that both BioC Sealer and MTA Fillapex provide a comparable seal in the middle and apical thirds of the root canal system, however, this was not statistically significant. This indicates their potential efficacy in both endodontic sealing procedures.

Published: May 2024

Background: Unrepaired dextro-transposition of great arteries (D-TGA) is well known for long-term complications, including tricuspid valve regurgitation, arrhythmias, and coronary artery abnormalities. Pulmonary hypertension (PH) is a frequent, progressive, and fatal complication in unrepaired CHD. This chronic condition can induce pulmonary thromboembolism (PTE). Aim: To report the management of PTE in unrepaired D-TGA with PH.
Case Presentation: We present a rare case of an eleven-year-old male in unrepaired D-TGA with PH. He came with hemoptysis with no sign of acute or chronic infection. This condition was not associated with endocarditis or tuberculosis. The patient underwent a CT-pulmonary angiography examination and found a filling defect in the apical and posterior branches of the right superior pulmonary artery, suggesting a PTE that caused pulmonary parenchymal infarction. He was treated with intravenous low molecular weight heparin (LMWH) for ten days (1 mg/kg) and tranexamic acid. On follow-up, he did not experience cardiovascular collapse or hypotension; by the day, the hemoptysis had decreased in frequency and volume. He received long-term warfarin (2 mg/day) for three months. After three months of follow-up, the PTE was not visualized from CT-pulmonary angiography.
Summary: Hemoptysis is rare and life-threatening in unrepaired CHD. Heparin administration continued with warfarin, and tranexamic acid provides a good prognosis in patients with PTE with D-TGA and PH.

Published: May 2024

There is a lack of study on the nature and scope of discrimination experienced by biracial children in the Philippines. Aiming to contribute to filling the gap, this article draws from a doctoral thesis that used an indigenous Filipino research approach to investigate Filipino biracial children’s view of their dignity. Biracial children from poor neighborhoods in Angeles City participated in the study. Their caregivers and some community members were also interviewed. The research found that colonial beliefs and practices led to formation of biases which triggered the discrimination experienced by the biracial child participants and negatively affected their dignity. The biases were manifested during incidences of bullying and name-calling, cultural/racial stereotyping, social stigma, not being consulted, and corporal punishment. Recommended measures to address discrimination include access to education and promotion of pakikipagkapwa (treating others as fellow human being).

Published: May 2024

The purpose of the publication is to analyze the methods of calculations of accuracy of construction works and geodetic control of erection of reinforced concrete foundation columns for overpass steel structures of thermal and gas-material pipelines of oil refineries. For this purpose, a calculation methodology is considered, which takes into account operational technologies, including construction works and geodetic control, during the erection of the above-mentioned structures. The obtained results show that in order to ensure the standardized limit deviations of construction works, interrelated reasonable accuracy standards in the erection of structures are required, taking into account the average weighted average errors of geodetic control. In regulatory documents for the erection of structures are given accuracy standards (limit deviations) on their final position, and on geodetic control are given without taking into account the technological processes accuracy indicators of construction works. Setting the liability indicator of structures by purpose, we are establishing a confidence probability of ensuring the construction accuracy of the structure. To analyze the construction works and geodetic control accuracy we used the following methods: equal and negligible influence of deviation on the final position of structures and the method taking into account the accuracy of construction’s technological processes. In this publication examples of error calculations using the above mentioned methods are given. It is established that the most justified tolerances for structures erection are obtained when the method is applied taking into account the accuracy of their construction technological processes (by the accuracy indicator of technological process of construction works the limiting errors of geodetic control are established).

Authors: GONZÁLEZ-ARESTIZÁBAL Tomás , MORALES Álvaro , AVAYÚ-ZALIASNIK Tania , CSENDES Attila , KORN Owen , FIGUEROA-GIRALT Manuel
Published: May 2024

ABSTRACT BACKGROUND: Small bowel obstruction (SBO) is a major problem in emergencies. Comorbidities increase morbimortality, which is reflected in higher costs. There is a lack of Latin American evidence comparing the differences in postoperative results and costs associated with SBO management. AIMS: To compare the risk of surgical morbimortality and costs of SBO surgery treatment in patients older and younger than 80 years. METHODS: Retrospective analysis of patients diagnosed with SBO at the University of Chile Clinic Hospital from January 2014 to December 2017. Patients with any medical treatment were excluded. Parametric statistics were used (a 5% error was considered statistically significant, with a 95% confidence interval). RESULTS: A total of 218 patients were included, of which 18.8% aged 80 years and older. There were no differences in comorbidities between octogenarians and non-octogenarians. The most frequent etiologies were adhesions, hernias, and tumors. In octogenarian patients, there were significantly more complications (46.3 vs. 24.3%, p=0.007, p<0.050). There were no statistically significant differences in terms of surgical complications: 9.6% in <80 years and 14.6% in octogenarians (p=0.390, p>0.050). In medical complications, a statistically significant difference was evidenced with 22.5% in <80 years vs 39.0% in octogenarians (p=0.040, p<0.050). There were 20 reoperated patients: 30% octogenarians and 70% non-octogenarians without statistically significant differences (p=0.220, p>0.050). Regarding hospital stay, the average was significantly higher in octogenarians (17.4 vs. 11.0 days; p=0.005, p<0.050), and so were the costs, being USD 9,555 vs. USD 4,214 (p=0.013, p<0.050). CONCLUSIONS: Patients aged 80 years and older with surgical SBO treatment have a higher risk of medical complications, length of hospital stay, and associated costs compared to those younger.

Published: May 2024

ABSTRACT BACKGROUND: Hepatic retransplantation is associated with higher morbidity and mortality when compared to primary transplantation. Given the scarcity of organs and the need for efficient allocation, evaluating parameters that can predict post-retransplant survival is crucial. AIMS: This study aimed to analyze prognostic scores and outcomes of hepatic retransplantation. METHODS: Data on primary transplants and retransplants carried out in the state of Paraná in 2019 and 2020 were analyzed. The two groups were compared based on 30-day survival and the main prognostic scores of the donor and recipient, namely Model for End-Stage Liver Disease (MELD), MELD-albumin (MELD-a), Donor MELD (D-MELD), Survival Outcomes Following Liver Transplantation (SOFT), Preallocation Score to Predict Survival Outcomes Following Liver Transplantation (P-SOFT), and Balance of Risk (BAR). RESULTS: A total of 425 primary transplants and 30 retransplants were included in the study. The main etiology of hepatopathy in primary transplantation was ethylism (n=140; 31.0%), and the main reasons for retransplantation were primary graft dysfunction (n=10; 33.3%) and hepatic artery thrombosis (n=8; 26.2%). The 30-day survival rate was higher in primary transplants than in retransplants (80.5% vs. 36.7%, p=0.001). Prognostic scores were higher in retransplants than in primary transplants: MELD 30.6 vs. 20.7 (p=0.001); MELD-a 31.5 vs. 23.5 (p=0.001); D-MELD 1234.4 vs. 834.0 (p=0.034); SOFT 22.3 vs. 8.2 (p=0.001); P-SOFT 22.2 vs. 7.8 (p=0.001); and BAR 15.6 vs. 8.3 (p=0.001). No difference was found in terms of Donor Risk Index (DRI). CONCLUSIONS: Retransplants exhibited lower survival rates at 30 days, as predicted by prognostic scores, but unrelated to the donor’s condition.

Resumo Objetivou-se mensurar o desempenho zootécnico e a qualidade de ovos de codornas japonesas alojadas sob diferentes densidades e alimentadas com rações contendo parede celular de levedura (PCL). Foram utilizadas 576 codornas japonesas (Coturnix japonica) com 43 semanas de idade e 76% de postura, com peso inicial de 158,50 ± 5,41 g distribuídas em delineamento inteiramente ao acaso em esquema fatorial 3 × 2 (três níveis de PCL: 0; 500 e 750 g.ton−1 e duas densidades de alojamento: 81,5 e 92,4 cm2/ave), com seis repetições de 17 e 15 codornas por unidade experimental, respectivamente. Foram avaliados: consumo de ração, produção de ovos/ave/dia, produção de ovos/ave alojada, produção de ovos comercializáveis, massa de ovos, conversão alimentar por dúzia e por massa de ovos e viabilidade das aves; peso do ovo, peso específico, porcentagem de gema, de albúmen e de casca e espessura da casca. Não houve interação entre os níveis de inclusão de PCL e densidade de alojamento para os parâmetros avaliados, exceto para peso do ovo. Codornas alojadas em gaiolas com 92,4 cm2/ave alimentadas com 500 g.ton−1 de PCL apresentaram maior peso do ovo. A espessura de casca foi influenciada de forma independente pela densidade de alojamento, a menor densidade (92,4 cm|2/ave) promoveu maior espessura de casca. A inclusão de 500 g.ton−1 de PCL na ração de codornas japonesas alojadas sob densidade de 92,4 cm2/ave melhora o peso dos ovos e a espessura da casca.

Resumo O objetivo deste trabalho foi avaliar as características bromatológicas e minerais do capim Marandu sob diferimento em monocultivo (MC) e em sistema silvipastoril (SSP) com 12 (SSP12) e 18 m (SSP18). O delineamento experimental foi em blocos ao acaso, onde cada sistema foi alocado individualmente. No centro de cada parcela formou-se cada tratamento em fatorial de 3 × 4, composto por três sistemas (MC e SSP12 e SSP18 entre as fileiras das árvores) e quatro períodos de diferimento (60, 90, 120 e 150 dias), perfazendo doze tratamentos com três repetições. Não houve efeito de interação entre os fatores (p>0,05) para proteína bruta (PB), fibra em detergente ácido (FDA), fibra em detergente neutro (FDN), fósforo (P), potássio (K), cálcio (Ca) e magnésio ( Mg). O teor de PB diminuiu com o incremento nos dias de diferimento, mas até os 75 dias atendeu a demanda sugerida para ruminantes. As concentrações de FDN e FDA aumentaram, enquanto os teores de P e K diminuíram com o incremento nos dias de diferimento. A concentração de Mg e Ca não diferiu com os dias de diferimento. No entanto, em relação aos sistemas avaliados houve diferença apenas para Mg, que foi maior em MC e SPS12, diferindo de SPS18. O espaçamento adotado no SSP de 12 e 18m não influencia negativamente o valor nutricional da planta forrageira. O período de diferimento de 75 dias a partir de março favoreceu a concentração de macronutrientes e o teor de PB no capim marandu tanto em MC quanto nos SSP.

Resumo A dinâmica folicular em ovelhas leiteiras é pouco compreendida. Neste trabalho foi avaliado a dinâmica folicular de ovelhas leiteiras, dentro e fora da estação reprodutiva observando o efeito de duas concentrações de progesterona (60 e 120mg) utilizadas em pessários vaginais na pré-sincronização. O experimento foi realizado nos meses de abril/maio e outubro/novembro, utilizando 40 ovelhas multíparas leiteiras hígidas, predominantemente da raça Lacaune, que foram submetidas a exames ultrassonográficos diários por via transretal. Na estação reprodutiva foram avaliados o número de ovulações (1,35 vs 1,05), o diâmetro(mm) do folículo ovulatório (5,97 vs 5,05), a duração da fase lútea (11 vs 9,14 dias) e a duração do ciclo estral (16,83 vs 16,6 dias) dentro da estação em comparação com fora da estação reprodutiva respectivamente. Fora da estação as ovelhas não apresentaram corpo lúteo no momento da inserção do pessário vaginal, caracterizando anestro. Mesmo com menor duração da fase folicular, o folículo ovulatório apresentou maior diâmetro na estação reprodutiva, sugerindo maior viabilidade e qualidade do oócito ovulado. A aplicação de progesterona exógena amplia a fase lútea na estação reprodutiva (11 vs 9,14 dias). O anestro observado fora de época sugere a necessidade de maior concentração de progesterona nos protocolos reprodutivos. Desta forma, é possível adaptar protocolos reprodutivos para diferentes épocas, sugerindo o uso de pessários vaginais com maior concentração de progesterona (120 mg) fora da estação reprodutiva. Os dados obtidos permitiram caracterizar a dinâmica folicular em ovelhas leiteiras, demonstrando suas diferenças em cada estação a partir do uso de diferentes doses de progesterona na pré-sincronização
Garantizar el derecho a una muerte segura y culturalmente adecuada: el sentido de las ocupaciones en la tríada vida-muerte-renacimiento desde la visión indígena Colombiana

Resumen El valor espiritual atribuido a la muerte, para los guardianes del corazón del mundo en la Sierra Nevada de Santa Marta, Colombia, como en otras culturas indígenas, integra una preparación social, física, ética, ecológica y emocional para hacer un acompañamiento saludable a la vida después de la muerte. Su importancia va mucho más allá de una visión relacionada con hechos espectaculares o la desmitificación de su cosmovisión como “pobre o vulnerable”. A través de una reflexión situada de los procesos de salud, enfermedad y cuidado en el contexto indígena del final de la vida, proponemos considerar el sentido de las ocupaciones en la tríada vida - muerte - renacimiento, para garantizar el derecho a una muerte segura y culturalmente adecuada. La dimensión ocupacional, como agente de construcción e interpretación de los significados colectivos de las comunidades indígenas a través de la espiritugogía precedida por su ancestralidad, puede ofrecer otras perspectivas interculturales de cuidados paliativos milenarios y un seguimiento diferenciado y respetuoso por parte de los sistemas de salud.

Resumo Introdução A partir da Residência Multiprofissional em Saúde (RMS) ocorre uma capacitação profissional mais direcionada para o Sistema Único de Saúde, visando a reorientação das lógicas tecnoassistenciais e contribuindo de forma significativa para a inserção e consolidação da fisioterapia na Atenção Primária à Saúde (APS). Objetivo Compreender a percepção dos profissionais e gestores de saúde sobre as contribuições da RMS para a inserção da fisioterapia na APS. Métodos Trata-se de um estudo qualitativo fundamentado na hermenêutica, desenvolvido no município de Aracati, Ceará, Brasil, com 15 profissionais por conveniência. A elegibilidade dos participantes centrou-se em profissionais de nível superior da APS em área urbana. A coleta de dados aconteceu de março a junho de 2023, através de uma entrevista semiestruturada elaborada pelos pesquisadores. A análise de dados ocorreu com base na leitura do material, organização em temáticas e interpretação por profundidade. Resultados O primeiro contato com a fisioterapia acontece em cenários que envolvem desde a consulta individual e compartilhada a programas de saúde na escola, cujas ações são otimizadas pela APS a partir da residência. As estratégias de cuidado da fisioterapia são inúmeras, principalmente ações centradas nos aspectos biopsicossociais. A inserção da fisioterapia na promoção da saúde é revelada pela inclusão do profissional em grupos de promoção da saúde. A educação em saúde na perspectiva multiprofissional é potencializadora do cuidado pelas ações de promoção e prevenção. Conclusão A residência multiprofissional fortalece a inserção da fisioterapia na APS e potencializa os cuidados primários.
