Bioaugmentation Technology was implemented in a South Korean slaughterhouse in order to meet stricter effluent standards. In the two years since introducing Bioaugmentation into the effluent treatment process, BOD, COD, SS, TN, and TP levels were maintained below required standards. The slaughterhouse has been able to reduce dosing costs associated with Bioaugmentation while sustaining improved effluent quality. With the help of Bioaugmentation, overall plant stability was improved, and previously proposed plant expansion proved to be unnecessary, resulting in significant capital avoidance.

English is crucial to achieve academic success and fulfil social needs of the language in today’s society. Several studies have reported that the reasons for learning English could facilitate learners to learn the language more seriously with the aim to be proficient and successful in acquiring the language. However, the reasons for learning the English language may be a factor that could lead to academic burnout. Therefore, this study explored the reasons for learning English and burnout among pre-university students. A quantitative approach was done to investigate reasons for learning English and its relation to students’ burnout. The survey used was derived from Pintrich and De Groot’s (1990) reasons for learning and Campos et al.’s (2011) causes of burnout. A purposive sample of 271 UiTM Centre of Foundation Studies students responded to the survey. The findings of this study revealed the affective component was the most significant cause of academic burnout due to maladaptive perfectionism whereby learners were concerned about making mistakes especially when they focused on learning English to excel in tests and examinations. Conclusively, the relationship between the reasons for learning English language and cause of burnout has prominent implications for academic institutions and educators to foster a positive and successful learning environment by providing resources and assistance programmes for students to manage academic difficulties and social stresses in English language learning.

Authors: Hidayat Kemas Muhammad Wahyu
Published: January 2024

Based on the results of data obtained from the Palembang city tourism office, activities providing information about tourism are not running optimally in reaching prospective domestic and foreign tourists because activities for conveying information about the attractiveness of tourist attractions through brochures, newspapers, and other print media, as well as events being held, are still ongoing. is temporary; in other words, the delivery of information has not become a routine activity by the Palembang City Culture and Tourism Office. Apart from that, the lack of information related to tourist attractions in Palembang can make it difficult for tourists to determine destinations and travel plans because descriptions of areas or tourist attractions, such as visualization of places and distances between one location and another, are unavailable. Therefore, tourists waste time looking for tourist attractions to visit. This research aims to develop a Digital Tourism Map application in Palembang City which is presented with Augmented Reality in the form of 3D Objects using the Markerless Method so that it can make it easier for local and outside tourists in the Palembang City Area to get to know the tourist attractions in Palembang City. One method currently being developed is the Markerless method; with this method, users no longer need to print a marker to display digital elements

Authors: Ngwoke Dr. Festus U.
Published: January 2024

In language development of a second-language learner, many factors can influence a learner positively or negatively. This paper focuses on the various corrupt influences on the English language of most young second-language users. This is established using a simple inference from a comparison between character development and language development in an individual and to illustrate the similar way in which both developments can negatively affect individuals/learners through the influence of certain factors. Such factors include society, social media, printed material, electronic media and other miscellaneous factors that contaminate the language of the people, especially, that of young second-language users. Observed actual instances of language corruption are rampart in the spoken and written expressions of these users, business names, mottos written on vehicles, etc. The paper goes further to discuss the implications of these negative influences as well as the roles expected of teachers of English, parents and the government concerning these stated corrupt influences.

Authors: Costa Paes Gonçalves Julio , Bonfim Lopes Ana Gabriela , Teixeira de Assis Carvalho Guilherme , Prado Paiva Helena , Azara de Oliveira Eric
Published: January 2024

Introdução: O carcinoma basocelular (CBC), um carcinoma de pele derivado de células epidérmicas, é o tumor maligno mais frequente em humanos. A cirurgia excisional e a ressecção em estágio de Mohs são os tratamentos mais eficazes para carcinomas basocelulares de baixo e alto risco. Durante as últimas décadas, a eletroquimioterapia (ECT) tornou-se uma terapia locorregional apreciada no campo da dermato-oncologia. Objetivos: avaliar a eficácia da ECT no tratamento de carcinomas basocelulares. Materiais e métodos: Trata-se de uma revisão integrativa, em que a questão norteadora foi “A eletroquimioterapia é uma opção eficaz e segura no tratamento de pacientes com carcinoma basocelular?”. A busca pelos artigos ocorreu no PubMed a partir dos termos “basal cell carcinoma”, “cisplatin”, “electrochemotherapy” e “bleomycin”. Resultados e discussão: A eletroquimioterapia é uma opção de tratamento que pode ser oferecida quando a cirurgia ou a radioterapia não são viáveis ou contra-indicadas. A eletroquimioterapia fornece seu efeito antitumoral através da permeabilização de células cancerosas a agentes quimioterápicos por meio de pulsos elétricos de curta e alta tensão que desestabilizam a barreira da membrana celular, permitindo seu acesso intracelular. As principais vantagens da eletroquimioterapia são o alto controle tumoral local com danos mínimos ao tecido normal, efeitos colaterais limitados e boa relação custo/benefício. Conclusão: Quando a excisão não é viável, a ECT é uma alternativa segura e razoavelmente eficaz, com maior chance de sucesso em indivíduos sem tratamento, cujos tumores estão totalmente cobertos com pulsos elétricos.

A Rare Case Report of Cardiac Sarcoidosis with Pulmonary Hypertension
Authors: Purnomo Nathania , Damay Vito Anggarino , Wicaksono Sony Hilal
Published: January 2024

Introduction: Cardiac sarcoidosis (CS) is a rare granulomatous disorder in which white blood cells form clusters on the myocardium. The clinical presentations of CS are varied, as is its etiology. Multiple diagnostic approaches to determine the cause of persistent dyspnea may fail, as cardiac sarcoidosis can mimic many other diseases.Case Report: A 47-year-old woman presented with a sudden onset of dyspnea and a history of chronic thrombo-embolic pulmonary hypertension (CTEPH). Multiple diagnostic approaches were employed, including a CT scan of the thorax with contrast, CT pulmonary angiography, CT coronary angiography, and a Ventilation/Perfusion test, but the results were inconclusive. A Cardiac MRI was ultimately performed, which led to a diagnosis of cardiac sarcoidosis.Case Discussion: The patient had been stable and asymptomatic over the years, despite her history of CTEPH, until she developed a sudden onset of dyspnea. The presence of pitting edema, ECG results, and echocardiography data initially suggested a diagnosis of congestive heart failure. However, tests from the pulmonary system and cardiac coronary were normal. This highlights the elusive nature of cardiac sarcoidosis, which can often go unnoticed and be frequently misdiagnosed. Given the inconclusive results from previous tests, a Cardiac MRI was performed to further characterize the pathology. This led to the findings of Late Gadolinium Enhancement (LGE) and the diagnosis of CS.Conclusion: Cardiac sarcoidosis is a master imitator of many diseases, with patients sometimes presenting with only dyspnea. In such cases, Cardiac MRI plays a pivotal role as a diagnostic test, especially when results from other diagnostic workups are nonspecific.

Published: January 2024

Introduction: Irrational use of antibiotics can lead to antibiotics resistance, necessitating efforts for prevention. The implementation of an Antimicrobial Stewardship Program aims to mitigate inapproriate antimicrobial prescribing. This study aims to compare antibiotic rationality based on quantity, quality, and total cost of antimicrobial utilization following the Antimicrobial Stewardship Program in a tertiary hospital setting.Methods: This was a cross-sectional study. Data were obtained from the medical record of 120 patients hospitalized in the pediatrics ward and classified into two groups: post-program and control. The quantity of antibiotic utilization was measured using Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD). Antibiotic rationality was assessed using Gyssens modified category. Normality was evaluated using the Kolmogorov-Smirnov test and analyzed with an independent t-test.Results: There was 10% increase of prudent antibiotic use and a 30.61% reduction in total cost in the post-program study group. However, there was no significant difference in the quantity of antimicrobial utilization in both groups (p=0.06).Conclusion: The program improves the rationality of prudent antibiotic prescription and reduces the total cost of antimicrobial utilization.
Estimulación medular eléctrica en ráfagas y tónica: mecanismos cerebrales comunes y diferentes.
Authors: De Ridder Dirk , Vanneste Sven
Published: January 2024

Objetivo: La estimulación medular eléctrica se usa generalmente para tratar el dolor médicamente incoercible. Para lograr la supresión del dolor se utilizan distintos diseños de estimulación como la estimulación tónica, la estimulación de alta frecuencia y la estimulación en ráfagas. Un análisis preliminar de los mismos datos utilizados en este estudio demostró que la estimulación en ráfagas probablemente modula las vías mediales de dolor, a diferencia de la estimulación tónica. El tema plantea qué mecanismos supraespinales comunes y diferentes usan la estimulación tónica y en ráfagas. Materiales y métodos: Se analizaron los datos clínicos y de electroencefalografía (EEG) de cinco pacientes sometidos a estimulación tónica, en ráfagas y simulada para observar las similitudes y las diferencias entre la estimulación en ráfagas y tónica. Se realiza un análisis de sustracción y conjunción de EEG de fuente localizada (sLORETA) en cada condición tanto para actividad como para conectividad funcional. Se calcula una relación entre la corteza cingular anterior dorsal (CCAd) y la corteza cingular anterior pregenual/corteza prefrontal ventromedial (CCAp/CPFvm) para reflejar un equilibrio entre sistemas de tolerancia del dolor y supresión del dolor.Resultados: Se observan diferencias en la CCAd, la corteza prefrontal dorsolateral, la corteza somatosensorial primaria y la corteza cingular posterior (CCP). La estimulación en ráfagas y tónica comparten la activación en la CCAp, el área parietal inferior, que abarca la corteza somatosensorial secundaria inferior, la CCP y el parahipocampo. La estimulación en ráfagas normaliza el equilibrio tolerancia del dolor/ supresión del dolor en contraposición a la estimulación tónica. Discusión y conclusión: Estos datos sugieren que tanto la estimulación en ráfagas como la estimulación tónica modulan el sistema descendente inhibidor del dolor (a través de la CCAp), así como también un sistema de memoria aversiva (a través del parahipocampo) contextual autorreferencial (a través de la CCP). No obstante, la estimulación en ráfagas normaliza el equilibrio tolerancia/supresión del dolor en contraposición al modo tónico por un efecto mayor sobre la CCAd.

Electroflotation Treatment of Industrial Wastewater in a Specially Designed Electroflotator Powered by a Solar Panel
Authors: Shoikhedbrod Michael
Published: January 2024

Currently, the anode in existing electroflotators is a dense mesh with small cells, which causes salt deposits to form on its surface during the electrolysis of waste water. In another case, the salt deposits completely cover the cells, which stops the electroflotation process by preventing the passage of electrolytic hydrogen bubbles through them. The use of an anode in the form of a dense mesh with small cells in electroflotators, on the one hand, increases the density of direct current flowing in industrial wastewater during electroflotation of industrial wastewater, and therefore increases the formation of microdispersed electrolytic hydrogen bubbles, which contribute to the successful electroflotation of industrial wastewater. On the other hand, the use of an anode in the form of a dense mesh with small cells in electroflotators sharply reduces the passage through this mesh of electrolytic hydrogen bubbles, formed during electroflotation of industrial wastewater, which sharply slows down electroflotation process. When the author devised electroflotation treatment for industrial wastewater in a specially built electroflotator, powered by a solar panel, this issue was resolved. The article presents a developed method of electroflotation treatment of industrial wastewater in a specially designed electroflotator, powered by a solar panel (solar cell), which includes an electrolysis base and uses negatively charged electrolytic hydrogen bubbles with a calculated dispersion, which release microscopic particles from wastewater in the process of wastewater treatment by floating up in the wastewater of the created by them strong complexes: negatively charged microdispersed electrolytic hydrogen bubbles + microscopic particles of wastewater from industrial wastewater in the process of an elementary act of flotation.

En el Panamá colonial, al igual que en el resto del imperio español, la sociedad estuvo dividida en tres razas principales: los blancos, los indios y los negros, ocupando estos últimos, en su mayoría, la condición de esclavos.  Sin embargo, al finalizar este periodo, la existencia de un grupo afrodescendiente fuera de este estatus social, por mínimo que fuera, evidencia una movilización, que ha tenido impacto en la formación identitaria de la nación, al desenvolverse en funciones fuera de la antes mencionada.  Por esta razón se busca cotejar investigaciones realizadas hasta el presente que abordan el tema y explican el desenvolvimiento social en mención.

El objetivo de este trabajo es validar la representatividad de dos modelos matemáticos, para aplicaciones de tratamiento de agua residual con consorcios microalgas-bacterias. Los modelos se validaron utilizando datos recolectados en condiciones ambientales de la Sabana de Bogotá (Colombia). La experimentación evaluó escenarios con diferentes proporciones de microalgas:agua residual, midió el crecimiento de la biomasa, así como la remoción de contaminantes. Los resultados muestran que los modelos representan el comportamiento de la biomasa, pero no son capaces de predecir la remoción de contaminantes del agua. Se observó remoción de DQO debido a las interacciones entre el consorcio de microalgas y bacterias, los mejores resultados fueron obtenidos en el escenario 25% de microalgas y 75% de agua residual. En general, el monitoreo del proceso de tratamiento demostró la producción de biomasa y la mejora en la calidad del agua tratada.

La sedimentación del embalse de Marmolejo incrementa el riesgo de inundación en el Municipio de Andújar (Jaén, España) situado en la cola del embalse. La administración hidráulica española ha diseñado una serie de medidas de protección cuya efectividad queda condicionada al nivel de sedimentación del embalse. Con la información batimétrica y de aforos de sedimentos en suspensión se ha calculado la ley de aportación de sedimentos al embalse. Ha sido necesario el empleo de técnicas de supercomputación y machine learning, así como un nuevo modelo de transporte de sedimento en suspensión, para calibrar un modelo numérico bidimensional del embalse, que ha permitido reproducir la evolución histórica del proceso de sedimentación. Finalmente se ha desarrollado una herramienta web que simula la sedimentación en el embalse en función del criterio de gestión de compuertas, a fin de optimizar la explotación del embalse y mantener la sedimentación en niveles de seguridad para Andújar.

A diferenciação do adulto jovem de sua família de origem é uma das principais tarefas da etapa de transição para a vida adulta. Partindo da perspectiva do ciclo vital, espera-se que o cumprimento desta tarefa facilite o processo de desenvolvimento nas fases subsequentes, como a da formação do casal. A partir deste pressuposto e da Teoria dos Sistemas Familiares de Murray Bowen, este estudo buscou verificar se a diferenciação do self prediz o compromisso e a satisfação com o relacionamento em jovens adultos casados ou coabitantes. Participaram 342 adultos com idades entre 20 e 29 anos, que residiam com seus(uas) parceiros(as). Os participantes responderam a um questionário sociodemográfico, à Escala de Qualidade Conjugal e ao Inventário de Diferenciação do Self - R. Análises de regressão múltipla indicaram que as dimensões corte emocional e posição do eu, da diferenciação do self, foram preditoras do compromisso e da satisfação conjugal, enquanto a reatividade emocional foi preditora apenas do compromisso. Esses achados corroboram a literatura internacional e reforçam a importância da diferenciação do self em adultos jovens, especialmente considerando a sua reverberação na trajetória relacional subsequente. Estes resultados podem auxiliar profissionais que atuam tanto em contextos clínicos quanto com estratégias de promoção de saúde na conjugalidade.

La fitotecnología a través de la fitorremediación, presenta ventajas definidas como la eficiencia y el costo reducido de su aplicación para la recuperación de suelos contaminados, en comparación con las técnicas fisicoquímicas convencionales. La investigación evaluó el potencial de las especies Medicago sativa y Taraxacum officinale para remediar suelos contaminados con metales pesados (plomo, mercurio y cadmio) en el botadero de residuos sólidos Yacucatina. Aunque la concentración inicial de plomo en el suelo (9,41 mg/kg) estaba por debajo del ECA de 70 mg/kg, la de cadmio (5,60 mg/kg) superaba el límite permitido de 1,4 mg/kg. Después de aplicar la fitorremediación con Medicago sativa, la concentración promedio de plomo disminuyó a 8,50 mg/kg y la de cadmio a 1,13 mg/kg, mientras que con Taraxacum officinale los valores finales fueron de 7,39 mg/kg para plomo y 1,36 mg/kg para cadmio, cumpliendo con los estándares ambientales. En términos de eficiencia de remoción, Medicago sativa mostró una eficiencia del 9,68 % para plomo y del 79,82 % para cadmio, mientras que Taraxacum officinale presentó una eficiencia del 21,57 % para plomo y del 75,71 % para cadmio; concluyendo que ambas especies demostraron ser promisorias para la descontaminación de suelos afectados por metales pesados.
