Published: March 2023

Atividades antrópicas tais como o uso e ocupação do solo de forma irregular e sem um prévio planejamento, vêm alterando a qualidade e características das águas levando a contaminação dos ecossistemas aquáticos. Em decorrência disso, inúmeros distúrbios sobrevêm nos ecossistemas de água doce modificando a composição, abundância e diversidade da biota, o que torna imprescindível a aplicação de uma gestão integrada que limite os impactos dos múltiplos usos das bacias hidrográficas e seus respectivos tributários. O objetivo deste trabalho é apresentar uma avaliação de uso e ocupação do solo utilizando os anos de 2000 e 2020 como referência, na sub-bacia do ribeirão Graipu pertencente ao município de Guanhães, mesorregião do Vale do Rio Doce (Minas Gerais / Brasil). Para a confecção dos mapas, foi utilizado o Sistema de Informação Geográfica (SIG), por meio do sistema de informação geográfica QGIS versão 3.22.1. Foram utilizados como referência os anos 2000 (marco inicial da crise hídrica) e 2020 com base na coleção 6 de Cobertura e Uso do Solo do MapBiomas. O presente estudo apontou que houve um sutil crescimento das áreas urbanas, silvicultura, formação florestal e mosaico de agricultura e pastagem em relação às demais áreas. Além disso, houve uma redução no uso do solo para fins de pastagens. Como conclusão, pode-se inferir que os resultados encontrados podem estar relacionados à criação e implementação de políticas públicas e com o aumento das discussões sobre a temática. É importante ainda a realização de trabalhos de educação ambiental considerando metodologias para proteção e técnicas de restauração e conservação de áreas, fomentando atividades de conscientização, além da valorização de bens e serviços ecológicos.

Published: March 2023

A sustainable business strategy is inevitable for 21st-century businesses. Consumers expect MSMEs to adopt sustainable strategies but realizing one's needs is the only impetus for any consumer. Thus, there is a gap between business sustainability practices and consumer expectations. This research identifies strategic sustainable business strategies to be integrated into business practices. This type of research uses exploratory qualitative methods. The type of data is primary data which is a direct answer from the informant. The data collection technique uses an interview method. The sampling design used non-probability sampling (snowball). The analysis technique is through data collection, data reduction, data presentation, and concluding because it can explain, assess, and visualize superior MSME empowerment modeling. The results of this study indicate that four strategies can be applied by MSMEs, including New vs. returning visitors, Bounce rate, Abandonment rate, and cost per conversion. The results of this study can contribute to the development of a technology-based sustainable business strategy which is expected to become the primary role model in increasing the competitiveness of MSMEs.

The Role of Good Corporate Governance in Moderating the Effect of Financial Ratio on Financial Distress (Study of Consumer Sector Companies Listed on the Indonesia Stock Exchange Over Period 2018-2020)
Authors: Riesta Gabriella Ika , Septriana Ira 
Published: March 2023

Financial distress is a condition where management fails to manage company finances. This study aims to determine the effect of leverage, net profit margin, liquidity, and sales growth on financial distress with corporate governance as a moderating variable. This sample used all consumer goods sector companies listed on the Indonesia Stock Exchange for the 2018-2020 period. Sampling was used with the purposive sampling technique and selected 25 companies. Data analysis used multiple linear regression and the absolute difference value test. The results are that the variables of leverage, net profit margin, and liquidity affect predicting financial distress. Meanwhile, sales growth does not affect financial distress. As measured by managerial ownership, corporate governance can moderate the effect of liquidity on financial distress. Still, it cannot moderate the effect of leverage, net profit margin, and sales growth on financial distress. Keywords:leverage, net profit margin, liqudity, sales growth, financial distress, good corporate governance

Authors: MEMİŞ Tuğçe , KABARAN Seray 
Published: March 2023

Objective: This study was conducted to evaluate the effect of an online nutrition training program about the Mediterranean diet for 8 weeks in overweight and obese female high school students on anthropometric measurements and diet quality.
Methods: A total of 86 students between the ages of 14-18 years were included in the study, and they were divided into two groups as nutrition training (n=44) and control groups (n=42). The Mediterranean Diet Quality Index (KIDMED) scores were calculated and anthropometric measurements of groups were taken by the dietician at the beginning and at the end of the study.
Results: The KIDMED score of the nutrition training group was 4.59±2.40 at the beginning, later on it increased to 7.43±2.57 after the program (p= .001). After the program, it was determined that the difference between the KIDMED scores of the nutrition training and control groups were statistically significant (p= .034), however the decrease in body weight (p= .09), BMI (p= .64), and waist circumference (p= .06) were similar between groups.
Conclusion: As a result of the study, it can be said that online nutrition training program about the Mediterranean diet for 8 weeks may affect the diet quality positively of overweight and obese female adolescents, but long-term programs should be planned to determine the effects on anthropometric measurements.

Published: March 2023

IntroductionThe extension of the Smale horseshoe construction for diffeomorphisms in the plane to those in spaces of at least dimension three may result in a hyperbolic invariant set referred to as a blender. The defining property of a blender is that it has a stable or unstable invariant manifold that appears to have a dimension larger than expected. In this study, we consider a Hénon-like family in ℝ3, which is the only explicitly given example of a system known to feature a blender in a certain range of a parameter (corresponding to an expansion or contraction rate). More specifically, as part of its hyperbolic set, this family has a pair of saddle fixed points with one-dimensional stable or unstable manifolds. When there is a blender, the closure of these manifolds cannot be avoided by one-dimensional curves coming from an appropriate direction. This property has been checked for the Hénon-like family by the method of computing extremely long pieces of global one-dimensional manifolds to determine the parameter range over which a blender exists.MethodsIn this study, we take the complimentary and local point of view of constructing an actual three-dimensional box (a parallelopiped) that acts as an outer cover of the hyperbolic set. The successive forward or backward images of this box form a nested sequence of sub-boxes that contains the hyperbolic set, as well as its respective local invariant manifold.ResultsThis constitutes a three-dimensional horseshoe that, in contrast to the idealized affine construction, is quite general and features sub-boxes with curved edges. The initial box is defined in a parameter-dependent way, and this allows us to characterize properties of the hyperbolic set intuitively.DiscussionIn particular, we trace relevant edges of sub-boxes as a function of the parameter to provide additional geometric insight into when the hyperbolic set may or may not be a blender.

Published: March 2023

The commercial activated carbon commonly uses to reduce of dye amount in the textile industry effluents. In this study has focused on the use of a natural clay sample as low cost but potential adsorbent. For this purpose the adsorption of commercial textile dyes, Astrazon Red FBL and Astrazon Blue FGRL, onto clay was investigated. The physicochemical and topographic characteristics of natural clay sample were determined by scanning electron microscopy (SEM), X-Ray fluorescence spectrometry (XRF), X-Ray diffraction (XRD), thermogravimetric analysis (TGA), and cation exchange capacity measurements. It was determined that the major clay mineral was smectite with partial impurities. The effects of several operational parameters such as contact time, initial dye concentration, temperature, and adsorbent dosage on the adsorption process were evaluated. The adsorption kinetics was interpreted with pseudo-first order, pseudo-second order, and intra-particle diffusion models. The equilibrium adsorption data were analyzed using Langmuir, Freundlich, Redlich-Peterson, and Temkin isotherm models. It was determined that the adsorption equilibrium was reached in the first 60 min for each dye. The amount of adsorbed dyes onto clay decreased with increasing temperature, similarly, it decreased with increasing sorbent dosage. The kinetic data were well described by pseudo-second order kinetic model, and adsorption equilibrium data was followed both Langmuir and Redlich-Peterson models for each dyes. The adsorption enthalpy and entropy values were calculated as −10.7 kJ.mol−1 and −13.21 J.mol−1.K−1 for astrazon red and those for astrazon blue −11.65 kJ.mol−1 and 37.4 J.mol−1.K−1, respectively. The experimental results support that the physical interactions between clay particles and dye molecules have an important role for the spontaneous adsorption of textile dyes onto the clay. This study revealed that clay could effectively be used as an alternative adsorbent with high removal percentages of astrazon red and astrazon blue.

BackgroundOptimal vancomycin trough concentrations and dosages remain controversial in sepsis children. We aim to investigate vancomycin treatment outcomes with a dosage of 40-60 mg/kg/d and corresponding trough concentrations in children with Gram-positive bacterial sepsis from a clinical perspective.MethodsChildren diagnosed with Gram-positive bacterial sepsis and received intravenous vancomycin therapy between January 2017 and June 2020 were enrolled retrospectively. Patients were categorized as success and failure groups according to treatment outcomes. Laboratory, microbiological, and clinical data were collected. The risk factors for treatment failure were analyzed by logistic regression.ResultsIn total, 186 children were included, of whom 167 (89.8%) were enrolled in the success group and 19 (10.2%) in the failure group. The initial and mean vancomycin daily doses in failure group were significantly higher than those in success group [56.9 (IQR =42.1-60.0) vs. 40.5 (IQR =40.0-57.1), P=0.016; 57.0 (IQR =45.8-60.0) vs. 50.0 (IQR =40.0-57.6) mg/kg/d, P=0.012, respectively] and median vancomycin trough concentrations were similar between two groups [6.9 (4.0-12.1) vs.7.3 (4.5-10.6) mg/L, P=0.568)]. Moreover, there was no significant differences in treatment success rate between vancomycin trough concentrations ≤15 mg/L and &gt;15 mg/L (91.2% vs. 75.0%, P=0.064). No vancomycin-related nephrotoxicity adverse effects occurred among all enrolled patients. Multivariate analysis revealed that a PRISM III score ≥10 (OR =15.011; 95% CI: 3.937-57.230; P&lt;0.001) was the only independent clinical factor associated with increased incidence of treatment failure.ConclusionsVancomycin dosages of 40-60 mg/kg/d are effective and have no vancomycin-related nephrotoxicity adverse effects in children with Gram-positive bacterial sepsis. Vancomycin trough concentrations &gt;15 mg/L are not an essential target for these Gram-positive bacterial sepsis patients. PRISM III scores ≥10 may serve as an independent risk factor for vancomycin treatment failure in these patients.

ObjectiveThe aim of this study was to describe the cumulative live birth rates (CLBRs) of young women with or without low prognosis according to the POSEIDON criteria after IVF/ICSI cycles and to investigate whether the diagnosis of low prognosis increases the risk of abnormal birth outcomes.DesignRetrospective study.SettingA single reproductive medicine center.PopulationFrom January 2016 to October 2020, there were 17,893 patients (&lt;35 years) involved. After screening, 4,105 women were included in POSEIDON group 1, 1,375 women were included in POSEIDON group 3, and 11,876 women were defined as non-POSEIDON.Intervention(s)Baseline serum AMH level was measured on the D2–D3 of menstrual cycle before IVF/ICSI treatment.Main outcome measure(s)Cumulative live birth rate (CLBR), birth outcomes.Result(s)After four stimulation cycles, the CLBRs in POSEIDON group 1, POSEIDON group 3, and non-POSEIDON group reached 67.9% (95% CI, 66.5%–69.3%), 51.9% (95% CI, 49.2%–54.5%), and 79.6% (95% CI, 78.9%–80.3%), respectively. There was no difference in gestational age, preterm delivery, cesarean delivery, and low birth weight infants between the three groups, but macrosomia was significantly higher in non-POSEIDON group, after adjusting for maternal age and BMI.Conclusion(s)The POSEIDON group shows lower CLBRs than the non-POSEIDON group in young women, while the risk of abnormal birth outcomes in the POSEIDON group will not increase.

BackgroundThe potential role of neprilysin (NEP) in glucose metabolism has been found by basic studies but lacks population evidence. The objective of this study was to examine the association between serum NEP and diabetes in Chinese adults.MethodsIn a prospective longitudinal cohort study – the Gusu cohort (n=2,286, mean age: 52 years, 61.5% females), the cross-sectional, longitudinal, and prospective associations between serum NEP and diabetes were systemically examined by logistic regression adjusting for conventional risk factors. Serum NEP was measured at baseline using commercial ELISA assays. Fasting glucose was repeatedly measured 4 years apart.ResultsThe cross-sectional analysis found a positive association between serum NEP and fasting glucose at baseline (β=0.08, P=0.004 for log-transformed NEP). This association persisted after controlling for the dynamic risk profiles during follow-up (β=0.10, P=0.023 for log-transformed NEP). The prospective analysis found that a higher level of serum NEP at baseline was associated with a higher risk of diabetes during follow-up (OR=1.79, P=0.039 for log-transformed NEP).ConclusionsSerum NEP was not only associated with prevalent diabetes but also predicted the future risk of diabetes development in Chinese adults, independent of many behavioral and metabolic factors. Serum NEP may be a predictor and even a new therapeutic target for diabetes. However, the casualty and mechanisms of NEP in the development of diabetes require further investigation.

IntroductionNormocalcemic primary hyperparathyroidism is a variant of primary hyperparathyroidism with consistently normal albumin-adjusted or free-ionized calcium levels. It may be an early stage of classic primary hyperparathyroidism or could represent primary kidney or bone disorder characterized by permanent elevation of PTH level. Aim of the studyThe study aims to compare the FGF-23 levels in patients with PHPT, NPHPT, and normal calcium and PTH levels.MethodsOur study included patients who were referred to the endocrinology clinic with a presumptive diagnosis of primary hyperparathyroidism, an isolated increased level of PTH, or reduced bone densitometry. For each patient, we performed blood analysis of FGF-23, calcium, phosphate, vitamin D [25(OH)D3], estimated glomerular filtration rate (eGFR), bone turnover markers, and urine analysis for calcium/creatinine ratio.ResultsOur study included 105 patients. Thirty patients with hypercalcemic hyperparathyroidism (HPHPT group), thirty patients with elevated PTH and normal calcium levels (NPHPT group), and 45 patients with normal calcium and PTH levels in the control group. FGF 23 level was 59.5± 23 pg/ml in the NPHPT group, 77 ± 33 pg/ml in the HPHPT group, and 49.7 ± 21.7 pg/ml in the control group (p=0.012). The phosphate level was lowest in the HPHPT group: 2.9 ± 0.6 vs 3.5 ± 0.44 in the NPHPT and 3.8 ± 0.5 in the control groups (p=0.001). No differences were found in eGFR, 25(OH)D3, C-terminal telopeptide type I collagen (CTX) and procollagen type 1 N-terminal propeptide (P1NP) levels, and bone densitometry scores between the three study groups.ConclusionOur findings suggest that NPHPT is an early stage of PHPT. Further studies are needed to determine the role of FGF-23 and its usefulness in NPHPT.
Eucalyptus woodlot adoption and its determinants in the Mecha District, Northern Ethiopia

Published: March 2023

IntroductionThe land area under Eucalyptus plantations has now significantly increased among Ethiopian smallholder farmers whereby Eucalyptus is grown on their farms in the form of a woodlot primarily for income generation. Despite its widespread adoption, studies and systematic documentation on its adoption and economic impact are inadequate to inform evidence-based policy development. The purpose of this study was to investigate the variables influencing the adoption of Eucalyptus woodlot in Mecha District, northern Ethiopia.MethodsA multistage sampling method was used to sample 186 respondent households from three villages namely Enashenifalen, Addisameba, and Rim in the district. Primary data was gathered through key informants (13), in-depth interviews, focus group discussions (3), and direct observations, which were complemented by data from secondary sources obtained from published and unpublished documents. A double-hurdle econometric model was used to identify factors influencing households’ adoption decisions and adoption intensity of Eucalyptus woodlot.Results and discussionThe findings indicate that household adoption decisions are significantly influenced by the number of parcels of land, off-farm work engagement, credit availability, and farmers’ perceptions of woodlot production. Family size (negatively), land holding size, number of parcels of land, market access, the adjacent farm, and farmers’ perceptions of Eucalyptus woodlot production all significantly influenced the adoption intensity of Eucalyptus woodlots. Furthermore, the major constraints were a lack of support and training, a lack of land segregation, and limited technologies. Providing support and training, alternative options for farmers, cluster planting, technology adoption, developing and implementing Eucalyptus policies, and enforcing rules and regulations are all areas that need to be addressed to improve the livelihood of the community.
Tree regeneration and spatial patterning among midtolerant tree species following gap-based harvesting in a temperate hardwood forest

Published: March 2023

IntroductionField experiments of gap-based harvest systems in temperate northern hardwood forests have provided inconsistent support for the theory that such regeneration approaches can improve regeneration success among increasingly underrepresented tree species intermediate in shade tolerance. We established a field experiment in Wisconsin, USA testing the long-term response of tree regeneration to group selection harvesting that created small (50 m2–D:H 0.32), medium (200 m2—D:H 0.64) and large (380 m2—D:H 0.88) gaps.Materials and methodsLight levels were modeled to test the assumption of resource heterogeneity within and across these gap sizes. Spatial statistics were used to assess whether the point patterns of saplings of several midtolerant tree species (Betula alleghaniensis, Carya cordiformis, Fraxinus spp.) mapped in harvest gaps provided evidence for partitioning across resource gradients 9 years post-harvest. Finally, we measured occurrence and height of all saplings within the harvest gaps to test the effects of gap size and deer exclusion fencing on the density and total height of shade-tolerant and midtolerant tree regeneration.Results and discussionLight levels progressively increased with gap size, varied by position within gaps, and provided significant evidence of resource heterogeneity. The complex light gradients formed both within and across the three gap sizes may partially explain the statistically significant clustering of Fraxinus spp. saplings in gap centers and north and east into the forested edge of medium and large gaps, C. cordiformis on the west sides of forested transitions surrounding large gaps, and B. alleghaniensis in the centers of large gaps. Densities of tolerant and midtolerant saplings were similar in medium and large gaps after nine growing seasons, though tolerant saplings averaged two meters taller across all three gap sizes. Our results show that gap-based silvicultural systems can create resource gradients that are sufficient to regenerate mixtures of species with high to intermediate tolerance of shade. However, prescriptions beyond harvesting and deer exclusion fencing may be necessary for the recruitment of midtolerant species to canopy positions.
