Published: January 2024

Abstract
Anaerobic digestion is a prevailing technology for the treatment and utilization of municipal organic solid waste (MOSW). In this technology, the macromolecular organic matter in waste degrades into small molecular substances through the anaerobic decomposition of microorganisms, producing biogas that can provide enormous energy. This paper focuses on the research progress of anaerobic digestion of various organic wastes for biogas production. The principle and process of anaerobic digestion for biogas production are introduced, along with the key factors affecting anaerobic digestion efficiency, such as temperature, pH, and sealing conditions. At the same time, the current cycle treatment technology and comprehensive treatment system of MOSW are also summarized. Furthermore, the paper explores biogas purification technologies, including desulfurization, deoxidation, drying, and decarbonization. Finally, the state-of-the-art of the utilization of MOSW for biogas production in the world and the problems faced by the utilization of MOSW for biogas production in China are reviewed. By summarizing the anaerobic digestion technology of MOSW, this review hopes to provide some reasonable solutions for the high-value utilization of MOSW.

Published: January 2024

Abstract
The article presents an investigation into Peak-to-Average Power Ratio (PAPR) reduction techniques in Optical Orthogonal Time Frequency Space (O-OTFS) modulation. Focusing on clipping and filtering as well as companding methods, the study explores their efficacy in mitigating PAPR challenges inherent in O-OTFS waveforms. The research evaluates the impact of these techniques on signal quality, particularly in the context of a Rician channel. Clipping and filtering (C&F) are examined for their ability to control amplitude peaks, while companding is analyzed for its role in optimizing dynamic range. The study conducts a comprehensive analysis of Bit Error Rate (BER) and power spectrum density (PSD) under varying conditions, shedding light on how these methods influence the reliability and robustness of OTFS communication. The investigation considers the interplay of these PAPR reduction methods with the unique characteristics of the Rician and Rayleigh channel, which includes a dominant line-of-sight component. The findings contribute valuable insights into designing efficient OTFS modulation systems for real-world scenarios. Ultimately, this research aims to provide a deeper understanding of PAPR reduction strategies in OTFS, offering guidance for optimizing signal processing techniques in communication systems where mitigating PAPR is crucial for achieving high performance and reliable data transmission. It is noted that the proposed C&F and companding algorithms outperform the conventional methods and achieved a PAPR gain of 1–3 dB and BER gain of 10.6–2 dB.

Abstract
Manipulating the spontaneous emission rate of fluorophores is vital in creating bright incoherent illumination for optical sensing and imaging, as well as fast single-photon sources for quantum technology applications. This can be done via increasing the Purcell effect by using non-monolithic optical nanocavities; however, achieving the desired performance is challenging due to difficulties in fabrication, precise positioning, and frequency tuning of cavity-emitter coupling. Here, we demonstrate a simple approach to achieve a wavelength-dependent photoluminescence (PL) lifetime modification using monolithic organic molecular aggregates films. These single monolithic organic films are designed to have a Lorentzian dispersion, including epsilon-near-zero (ENZ) and epsilon-near-pole (ENP) spectral regions with increased and decreased photonic density of states, respectively. This dispersion leads to enhanced and depressed PL decay rates at different wavelengths. Both time-resolved photoluminescence (TRPL) and fluorescence lifetime imaging microscopy (FLIM) measurements are implemented to verify the validity of this approach. This approach offers a promising way to design dual-functional optical sources for a variety of applications, including bioimaging, sensing, data communications, and quantum photonics applications.

Published: January 2024

Abstract
The impact of noise can arise from the operation of a mineral ore processing plant in the mining industry, such as PT Freeport Indonesia. The use of advanced technology in modern industry, like SAG#3, has increased production productivity but can also lead to noise emission issues that may endanger workers’ health. This research aims to project the impact of noise in the workplace at a new mineral ore processing plant using dynamic system analysis. Noise sampling was conducted using a sound level meter instrument following SNI 7231:2009. After data collection, dynamic system analysis was performed using Vensim Pro software, involving steps such as causal loop design, stock flow diagram formation, and model verification testing. The analysis results indicate that the noise level exceeds the permissible exposure limit, measuring at 85 dBA. Therefore, the implementation of a Hearing Conservation Program (HCP), personal protective equipment (PPE) policies, and periodic noise control policy evaluation are crucial steps in reducing the impact of noise on employees. This study highlights the need for concrete actions by the company, such as improving the effectiveness of the HCP, enforcing stricter PPE policies, and conducting regular evaluations. Consequently, the company can create a safer work environment and reduce the health risks associated with noise exposure in the workplace.

Published: January 2024

Mild, moderate, severe, and critical COVID-19 are associated with hyperinflammation. The CRP and ferritin are acute phase proteins that marks incidence of inflammation and used as the paramaters of hyperinflammation. This study aimed to determine the validity of CRP and ferritin level examination in moderate and severe COVID-19 since the time of admission. This was a cross-sectional analytical retrospective study with on moderate and severe COVID-19 patients admitted to Dr. Hasan Sadikin General Hospital Bandung, Indonesia, during the period of March 2020 to December 2020. The CRP and ferritin levels were obtained since the beginning of admission to the fourth day since admission on patients without any history of anemia. Subjects in this study were divided into moderate and severe COVID-19 groups based on the 3rd edition of COVID-19 Prevention and Control Guideline issued by the Ministry of Health Republic of Indonesia. Each group consisted of 30 subjects. The cut-off value was 7.65 mg/dL (AUC 0.698) for CRP and 963.1 mcg/L (AUC 0.938) for ferritin. The validity of ferritin vs CRP were reflected respectively as follows: 93.3% vs 76.7% sensitivity; 80.0% vs 63.3% specificity; 82.4% vs 67.6% PPV; and 92.3% vs 73.1% NPV. The validity of ferritin was proven to be superior as it significantly increases since day one, persisted longer and reaches its peak on the16th day. Meanwhile, CRP increases within 6-8 hours and reaches its peak within 48 hours after inflammation, then declines soon afterwards.

Road infrastructure has caused severe impacts on the environment and wildlife. Understanding and mitigating these effects are essential conservation measures. This study aimed to evaluate wildlife mortality due to animal-vehicle collisions along an 80-km stretch of the Tapir Rocha Highway (RS–040). The field inventory was carried out between August 2015 and March 2019. Once a week, two observers drove along the highway at an average speed of 40 km/h and all the vertebrate roadkill spotted from the car were assessed to record the species, carcass condition, and the roadkill locations along the road. In total, 2,371 dead animals were recorded and categorized into 137 species. The most affected classes were mammals (n = 1,223), and birds (n = 704). The most affected wild species were white-eared opossums (Didelphis albiventris, n = 559), black-and-white tegus (Salvator merianae, n = 129), and coypus (Myocastor coypus, n = 102). Carcass exposure assessments indicated that many (n = 637) of the animal deaths occurred the night before our arrival, which may suggest that nocturnal species were among the most vulnerable to mortality. Roadkill sighting peaked in the spring (34%) and summer (25%), probably due to reproductive activity and juvenile dispersal. Evident seasonal variations included a 50% reduction in reptile roadkill rates in autumn-winter compared to spring-summer, and a 20-percentage-point increase in the number of mammal road deaths in the winter. The reduced activity that reptiles display at low temperatures, and seasonal changes in carnivore food habits may explain these respective findings. While most of the animal victims of roadkill were common and widely distributed species with abundant populations, decreasing abundance of these species is a growing conservation concern.

A korai és lokálisan előrehaladott colontumorok esetében a megfelelő onkológiai minőségű sebészi resectio a kezelés központi eleme. Jobb oldali vastagbél tumorok sebészi ellátásában – a kedvezőbb hosszú távú onkológiai eredmények elérése céljából – egyre szélesebb körben elfogadott a Hohenberger által 2009-ben elsőként publikált „complett mesocolicus-excisio” (CME) és centrális érlekötés (CVL).Esetünkben egy 78 éves nőbeteg jobb alhasi faeculens váladékozása miatt indult kivizsgálása során a hasfalat szélesen infiltráló coecum tumor igazolódott. Az Onkoterápiás Bizottság – tekintettel az egyértelmű távoli áttét hiányára, a beteg jó általános állapotára, a fennálló colo-cutan sipolyra és egyértelmű irresecabilitási jelek hiányára – műtétet javasolt. A kuratív intenció és kellő radikalitás érdekében, komplett mesocolicus excisio és kiterjesztett hasfali resectio mellett döntöttünk. A műtét során a kialakult hasfali defektus rekonstrukciójához a jobb comb lateralis felszínéről tensor fasciae lateae musculocutan (TFL) lebenyt preparáltunk. A hasfali defektust, mind a fascia, mind a subcutis-cutis rétegében helyreállítottuk, a donor területet primeren zártuk. A posztoperatívumban a lebeny distalis végén vénás pangás jelei majd felületes necrosis mutatkozott. Sorozatos necrectomia és negatívnyomás-terápia (NPWT) mellett a hasfal végig intakt maradt és per secundam gyógyult.Megfelelő betegszelekció esetén, centrumokban elvégezve – onkosebész és helyreállító plasztikai sebész szoros együttműködésével – a radikális műtét kiterjesztett hasfali resectiót igénylő jobb colonfél tumoroknál is biztonsággal elvégezhető.

Published: January 2024

Background: The clinical importance of early identification of potential predictors of cardiovascular events in women with gestational diabetes mellitus (GDM) cannot be overemphasized. Thus, this study was aimed to determine the levels of selected cellular inflammatory markers and Castelli I and II risk indices in women with GDM. Methods: A total of 40 pregnant women, consisting of 11 women with GDM and 29 women without GDM, were randomly enrolled in this case-control study using the convenient sampling method. After participants fasted overnight, venous blood samples were taken, and the plasma lipid profiles were determined using the spectrophotometric methods. Then, differential white blood cells counting was done using a microscope. Thereafter, plasma low-density lipoprotein cholesterol (LDL-C) levels, Castelli risk index-I (CRI-I) and CRI-II, neutrophil-lymphocyte ratio (NLR), and monocyte lymphocyte ratio (MLR) were calculated using the appropriate formula. Student’s t-test, Mann Whitney U, Chi-square, and Spearman’s rho correlations were used for statistical analysis. P-values less than 0.05 were considered statistically significant.Results: Mean age, gestational weight, fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), LDL-C, and neutrophil count were significantly higher in women with GDM. Likewise with the Castelli I and II risk indices values, as well as the NLR. In contrast, HDL-C levels, lymphocytes, and monocytes counts were significantly lower in women with GDM. However, the two groups observed no difference in the MLR ) .Conclusion: Gestational diabetes mellitus is associated with dyslipidemia and systemic inflammation, which are forerunners of cardiovascular diseases.

Published: January 2024

Diante da nova configuração do Ensino Médio, surgiram os itinerários formativos, que possibilitam a flexibilização do ensino. Em Santa Catarina, a Educação Financeira ganhou este formato, anteriormente se apresentava na Estratégia Nacional de Educação Financeira (ENEF) e como tema transversal da Base Nacional Comum Curricular (BNCC). Ela tem como objetivo o planejamento financeiro pessoal em busca da saúde financeira e qualidade de vida. Mas como componente curricular eletivo (CCE), ela apresenta um desafio ainda maior: propor um ensino contextualizado com a realidade e projeto de vida do estudante, de modo a criar um sentido e motivação. O estudante deve ser o protagonista no processo. Deste modo, este estudo visou verificar quais as percepções de estudantes que cursaram o respectivo CCE em uma escola da educação básica de Santa Catarina. O estudo foi submetido ao comitê de ética em pesquisa da Universidade do Extremo Sul Catarinense (UNESC) e, após a aprovação, foram coletados os documentos de consentimento e realizada a aplicação de um questionário. Foi realizada a organização e análise descritiva dos dados. Encontrou-se o planejamento e autonomia financeira e consumo consciente como objetivos e motivos do estudante para cursar Educação Financeira. Em conformidade com os objetivos de aprendizagem e unidades temáticas do componente curricular eletivo definido em seu documento norteador. Além disso, ainda foi verificado o alinhamento com suas vidas pessoais e projetos de vida. Nesse contexto, há evidências que o ensino da Educação Financeira associado com os objetivos dos estudantes, pode proporcionar um sentido e uma aprendizagem mais significativa.

Authors: Endlich Angela Maria , Mattos Alves Larissa , Teixeira Juliana Carolina 
Published: January 2024

O contexto contemporâneo impõe reflexões sobre as pequenas cidades/localidades que se fazem urgentes e emergentes especialmente após período pandêmico. Esse período vivido de 2020 a 2022 provocou alterações talvez ainda não suficientemente mensuradas e compreendidas. A partir disso, emergiram novos questionamentos a respeito dos rumos da urbanização. Nesse sentido, o questionamento que orienta este artigo é compreender quais tendências podem ser observadas na realidade de pequenas cidades/localidades relacionadas ao avanço desse cenário. Norteado por essa questão o artigo teve como objetivo central construir reflexões sobre as perspectivas das pequenas cidades/localidades frente aos obstáculos contemporâneos. Para atender a tal tarefa os procedimentos metodológicos adotados foram a revisão da literatura e o levantamento de dados socioeconômicos das pequenas cidades/localidades da Região Intermediária de Maringá. Ao sistematizar os desafios atuais foram desenvolvidos três itens. No primeiro, refletimos acerca do processo de urbanização brasileiro e as pequenas cidades/localidades em contexto que pondera minimamente questões trazidas pela pandemia. Posteriormente, abordamos os enfrentamentos peculiares a áreas geograficamente periféricas. Procuramos analisar essa realidade socioespacial com o apoio de indicadores como o PIB per capita, contraposto ao índice de Gini que contribui para mensurar as desigualdades socioespaciais. Por fim, esboçamos algumas perspectivas, trazendo ideias considerações de autores que igualmente buscam caminhos frente aos desafios atuais. Compreendemos que diante aos novos desafios parece pertinente considerar que existem potencialidades nas pequenas cidades/localidades que podem contribuir para a produção de uma realidade socioespacial mais humana, socialmente menos desigual e ambientalmente sustentável.
Evaluation of hearing impairment in patients with Down syndrome
Authors: Sienkiewicz Katarzyna , Kochanek Krzysztof 
Published: January 2024

IntroductionIt is estimated that the prevalence of hearing loss in children with Down syndrome (DS) ranges from 38% to 82%. However, the diagnosis of hearing loss in DS is difficult, due to an impaired ability to cooperate for subjective tests. Thus, objective tests such as impedance audiometry, otoacoustic emissions, and auditory brainstem responses (ABRs) may be more appropriate. In this study objective methods without anesthesia were used to determine the amount, type, and prevalence of hearing loss in people with DS.Material and methodsThe study included 39 subjects with DS, ranging in age from 1 year to 27 years. Hearing tests in DS subjects were performed during physiological sleep or while awake. Otoscopic examination was performed in all DS subjects. If no abnormalities were seen, tympanometry, otoacoustic emissions, and recording of ABRs were attempted.ResultsObjective hearing tests showed that the DS group had various types of hearing disorders. Based on all objective tests carried out in all ears (<i>n</i> = 78), the following diagnoses were made: normal hearing, 36 ears (46%); cochlear hearing loss, 27 ears (35%); conductive hearing
loss, 8 ears (10%); suspected deafness, 7 ears (9%). Based on wave V thresholds, the following degrees of hearing loss were established: normal hearing, 36 ears (46%); 21–40 dB nHL, 21 ears (27%); 50–60 dB nHL, 8 ears (10%); 70–80 dB nHL, 6 ears (8%); > 80 dB nHL, 7 ears (9%).ConclusionsIn previous studies of DS subjects by other authors, conductive hearing loss predominated, followed by sensorineural hearing loss. In the present study, more sensorineural than conductive hearing loss was diagnosed. In most cases, the diagnosis of the type of hearing
disorder was based on the ABR result, and other tests such as tympanometry and otoacoustic emissions played a supporting role. Due to the often limited cooperation of the patient, the DPOAE test was difficult to perform.
