Published: August 2021

Assets consist of immovable and movable objects, both tangible and intangible assets, which are included in the fortune of an agency, organization, business entity or individual. The wrong management of assets will be bad for the company so that it is resulting in losses. Utilization of assets cannot be carried out optimally because they are not clearly identified, making it difficult to know which assets can still be used or when it is time to replace them and when it is time to carry out maintenance. Assets really need to be managed and utilized properly in order to maintain high asset value and to achieve optimal use and utilization of assets so as to provide more benefits for the company. The purpose of this research is to develop an asset management information system called SIMA+. The system development methodology used is prototyping. The system design uses Microsoft Visual Studio 2015 with the programming language Visual Basic, the system output design uses Crystal Report, and data storage uses Microsoft SQL Server 2014. The result of this paper is a system that is expected to have the ability to maintain asset value, asset service life, and asset security, minimizing asset utilization transaction errors and can adjust asset data recorded in the system and physical asset data.

Speech recognition is one of the important research fields which is currently widely used for various applications. However, speech recognition performance is affected by the dialect of the speaker. Therefore, dialect recognition is often used as an additional feature in speech recognition. The process of recognizing dialects is not easy. Currently, Machine Learning technology is widely applied in dialect recognition. One of the challenges in the introduction of machine learning-based dialects is the imbalance of classes and overlaps in a wide variety of classification techniques. This study applies Random Forest-based oversampling technology for dialect recognition. For hyper-parameter optimization of the random forest algorithm, we apply the Grid Search method. Experiments on Speech Accent Archive data using the MFCC feature resulted in an accuracy of 0.91 and AUC of 0.95

Published: August 2021

Imbalance data is a condition which there is a distinction in the quantity of data that results withinside the majority class (classes with very many members) and minority class (classes with very few members). It can complicate the classification process since the machine learning algorithm method is designed to classify already balanced data. The oversampling process technique is used to resolve data imbalance by applying synthetic data to the minority class in such a manner that it has the same volume of data as the majority class. MWMOTE is an oversampling technique that generates synthetic data based on members of the minority class clusters that are close to the majority class. This approach is capable of generating synthetic data well. The resulting synthesis data remains in the nearby majority region and too dense on the border of the cluster. It is hence permitting the resulting synthetic data to go into the majority class classification. This study is objectives to improve the process of generating synthetic data on MWMOTE so that the resulting data is extensively dispensed withinside the minority class. The outcomes of the test show that the proposed method is capable of enhancing the classification performance for KNN and C4.5 Decision Tree classification sequentially by 0.46% and 0.96% compared to MWMOTE

Authors: Brugnara Eduardo Cesar , Sabião Rafael Roveri
Published: August 2021

Recommendations of rootstocks for ‘Valência’ sweet orange in southern Brazil have been partially based on empirical observations or information. Therefore, this study compared young ‘Valência’ trees budded on different rootstocks in western Santa Catarina, Brazil. Seventeen rootstocks were tested for growth (tree height and canopy projection area and volume) and fruit production (per tree, hectare, m² and m³ of canopy). The experiment comprised four replicates of three trees and was carried during six years under standard management, in a Cfa (humid subtropical) climate. In general, larger trees produced more fruit. However, ‘San Diego’ citrandarin, ‘Swingle’ citrumelo, ‘Cravo’ rangpur
lime (among vigorous rootstocks), ‘Cravo’ x ‘Sunki’ EEI hybrid, ‘Fepagro C37 Dorneles’ citrange, ‘Rubidoux’ trifoliate orange (among medium vigorous rootstocks), ‘HFD25 EEI’ hybrid and ‘Flying Dragon’ trifoliate orange (among less vigorous rootstocks) stood out in cumulated production by area or volume of the canopy. ‘San Diego’ also stood out in production per tree. Cultivars ‘Cravo’ x ‘Sunki’ EEI, ‘San Diego’, and ‘HFD25 EEI’ should be further evaluated regarding disease susceptibility and fruit quality for possible release.

Authors: Rattalino Donna , Otero María Laura , Moriconi D. N. , Rivera P. C.
Published: August 2021

La olivicultura está afectada por un síndrome que genera marchitez en la copa del árbol. Uno de los microorganismos responsables es el hongo Verticillium dahliae, que provoca la enfermedad denominada verticilosis del olivo (VO). Según la severidad de los síntomas, se distinguen dos patotipos, defoliante (D) y no defoliante (ND). Su diagnóstico emplea la reacción en cadena de la polimerasa (PCR). Nuestro objetivo fue comparar la eficiencia de dos juegos de cebadores para detectar en planta el patotipo ND, el único presente en Argentina, mediante PCR anidada. Para ello se utilizaron los juegos de cebadores NDf/NDr - INTND2f/INTND2r (PCR-I), empleados comúnmente, y una nueva combinación, INTNDf/INTNDr - INTND2f/INTND2r (PCR-II). Se analizaron muestras de olivos sintomáticos de 39 fincas de la provincia deLa Rioja. PCR-II tuvo mayor eficiencia en la detección, 57,8 % frente a 16,7 % de PCR-I. PCR-II amplificó en casi todas las variedades, edades de plantas y niveles de severidad de la enfermedad, mientras que PCR-I detectó el hongo sólo en variedades muy susceptibles y con niveles de severidad leve. El uso de PCR-II para detectar a V. dahliae en olivo permitirá estudios más precisos sobre su incidencia que contribuirán al manejo adecuado de la verticilosis.

Sunspot magnetic fields: a comparison between the CrAO and SDO/HMI data
Authors: Biktimirova Regina , Abramenko Valentina
Published: August 2021

We performed a digitization of maximum magnetic field measurements in sunspots. The original data were acquired as drawings at the Crimean Astrophysical Observatory of the Russian Academy of Sciences (CrAO RAS). About 1000 sunspots observed in 2014 have been analyzed. The data were compared to the corresponding measurements from the SDO/HMI instrument (with both the line-of-sight magnetic field Bz(HMI) and the modulus of the magnetic field vector B(HMI)). For the same sunspot, the maximum modulus of the magnetic field derived at CrAO was compared to the corresponding value from HMI. The Crimean data and the space-based data (of both types) were found to be in direct proportion to each other. A linear approximation over the entire range of measurements (1–4) kilogauss (kG) shows a Pearson correlation coefficient of 0.71 (with the 95 % confidence boundaries of 0.68–0.74) and a slope of linear regression of 0.65±0.02 for both types of the space-based data. A linear approximation over the range of strong fields B(CrAO) > 1.8 kG gives a similar correlation, however the slope of linear regression is far closer to unity and constitutes 0.90 for the relationship (Bz(HMI) vs B(CrAO)) and 0.84 for the relationship (B(HMI) vs B(CrAO)). In the range of weak fields B(CrAO) < 1.8 kG, a non-linear deviation (exceeding) of the space-based data is observed. Non-linearity can be explained, in part, by a specific routine of the magnetic field measurements at CrAO, however further investigations are needed to explore sources of possible non-linearity in the HMI data. The Crimean measurements of the maximum magnetic field in sunspots are concluded to be in good agreement with the corresponding SDO/HMI measurements, and therefore they can be used for scientific purposes.

Unfolding the Decision-Making Dynamics of News Visualization Production in China
Authors: Ma Qian
Published: August 2021

News visualization is a journalistic form that centers on delivering information through data visualizations. It is arousing the interest of journalism professionals and scholars worldwide, including those in non-western societies. Limited studies have identified the challenges and opportunities of news visualization's adoption in non-western newsrooms, but the professionals' considerations and actions to deal with these challenges and seize the opportunities are unknown. This study explores the criteria for a valuable news visualization and how professionals balance the criteria and constraints to make news decisions in the newsrooms in China. A grounded analysis drawing on 15 in-depth interviews with professionals reveals the dynamics of source selection, interpretation, and presentation in news visualization production. It also shows that news visualization stories result from the debating and tradeoffs between the "western norms" and the organization's expectations, audiences' preferences, news commercialization, and macro environment in China.

A systematic review on autistic people’s experiences of stigma and coping strategies
Authors: Han Emeline , Scior Katrina , Avramides Katerina , Crane Laura
Published: August 2021

Autism can be understood as a concealable stigmatised identity. This is the first systematic review to synthesise the literature on autistic people’s experiences of stigma and coping strategies. 2877 records were screened and 27 studies included in this review. The reviewed literature demonstrates that autistic individuals are acutely aware of being stereotyped, judged, and discriminated by others. Autistic people also show signs of internalising stigma, rendering them more vulnerable to low self-worth and poorer mental health. To manage the impact of stigma, the included studies suggest that autistic individuals may use these strategies: concealment and camouflaging, selective disclosure and self-advocacy, as well as positive reframing and reconstructing identity. However, the evidence is limited and mixed in terms of how helpful and effective these strategies are. Future studies should include autistic populations with a wider range of intellectual abilities and explore interventions that seek to support autistic people in managing stigma. The power of language in perpetuating and challenging stigma also has important implications for research and practice, underscoring the need for researchers and practitioners to reflect carefully on the messages they are communicating about autism.

ClockBoard: a zoning system for urban analysis
Authors: Lovelace Robin , Tennekes Martijn , Carlino Dustin
Published: August 2021

Zones are the building blocks of urban analysis. Fields ranging from demographics to transport planning routinely use zones — spatially contiguous areal units that break-up continuous space into discrete chunks — as the foundation for diverse analysis techniques. Key methods such as origin-destination analysis and choropleth mapping rely on zones with appropriate sizes, shapes and coverage. However, existing zoning systems are sub-optimal in many urban analysis contexts, for three main reasons: 1) available administrative zoning systems are often based on somewhat arbitrary factors; 2) evidence-based zoning systems are often highly variable in size and shape, reducing their utility for inter-city comparison; and 3) official zoning systems are non-existent, not publicly available, or are too coarse, hindering urban analysis in many places, especially in low income nations. To tackle these three key issues we developed a flexible, open and scalable solution: the ClockBoard zoning system. ClockBoard consists of 12 segments divided by concentric rings of increasing distance, creating a consistent visual frame of reference for cities that is reminiscent of a clock and a dartboard. This paper outlines the design, potential uses and merits of the ClockBoard zoning system and discusses future avenues for research and development of new zoning systems based on the experience.
The Influence of the Place Value System on Symbolic Number Perception
Authors: Oberholzer Yvonne , Lindskog Marcus , Scheibehenne Benjamin
Published: August 2021

Past research on numerical cognition has suggested that both symbolic and non-symbolic numbers are mapped onto the same compressed mental analogue representation. However, experiments using magnitude estimation tasks show logarithmic compression of symbolic numbers while the compression of non-symbolic numbers has a power-function shape. This warrants closer inspection of what differentiates the two processes. In this study, we hypothesized that estimates of symbolic numbers are systematically shaped by the format in which they are represented, namely, the place value system. To investigate this, we tested adults (N = 188) on a magnitude estimation task with unfamiliar base-26 and base-5 scales. Results reveal that adults showed systematic, logarithmic-looking underestimation on both scales, indicating that the place value system itself can cause the pattern. Additionally, the observed shape of participants’ estimates on both scales could be well explained with a simple model that assumed insufficient understanding of exponential growth (i.e., a characteristic of place value systems). Taken together, our results suggest that the discrepancy between symbolic and non-symbolic number compression can be explained by taking the effect of the place value system into account.

Nudges are defined as small adjustments in the choice architecture that help people perform desirable behavior. How nudges interact with individuals’ motivation has not been studied empirically. We conducted three studies with different types of defaults in three different behavioral domains and investigated how defaults and different types of motivation affect choice outcomes. In Study 1, we investigated the effectiveness of a default to stimulate healthy eating choices implemented in a hypothetical online supermarket setting. In Study 2, we used a scenario in which participants could choose from a list of green amenities (either preselected or not). In Study 3, we asked participants if they wanted to participate in a basic or longer version of our questionnaire, with the longer version option set as the default in the nudge condition. Across three studies we show that defaults are effective in promoting desirable behavior, and that goal strivings and autonomous motivation have additional positive main effects. We did not find evidence that controlled motivation did affect behavioral outcomes. Exploratory analyses revealed that amotivation negatively affected behavior, but the measure had poor reliability. No significant interaction effects were observed. Together, these studies imply that both defaults and motivation have main effects on behavior, such that the default sets the anchor from which people can adjust according to the type and strength of their motivation. Implications for the practice and ethics of nudging are discussed.
Effects of silicon in plants with particular reference to horticultural crops - Review article

Silicon (Si) has long been considered as non-essential element for plant’s growth and production. Numerous efforts are being made for the discovery of its beneficial effects with large scale studies laying foundation for new findings and hypotheses. Therefore, Si has been suggested to be a quasi-essential element due to its positive effects against biotic and abiotic stresses alike. Though Si is the second most abundant element in the soil profile, its availability to plants is limited to the form of monosilicic acid only. Besides, plants’ ability to take-up Si and use it in their physiological processes also depends on the available transporters associated with it. Thus, the present review covers uptake and transport of silicon in plants as well as Si mediated physiological processes, including mechanisms underlying induced tolerance against biotic and abiotic stresses with a particular emphasis on horticultural species.
Comparative analysis of sour cherry cultivars on their ecological and biological indicators
Authors: Surányi D.
Published: August 2021

Sour cherries developed in the northern hemisphere, an alloploid hybrid of dwarf sour cherries (Prunus fruticosa) and bird cherries (P. avium), born in the confluence of the two species. However, the ecological and, above all, cold tolerance of the ancestor of cultivated sour cherries is higher than that of wild cherries (De Candolle, 1894; Rehder, 1954; Terpó, 1974; Iezzoni et al., 1991; Faust & Surányi, 1997). The cultivation limits are in the northern hemisphere 38-44. degree. The Carpathian Basin, the Balkans and Asia Minor are considered to be the main birthplaces for sour cherries. The genetic and morphological diversity of sour cherries is greater than that of the basic species (Iezzoni et al. 1991; Faust & Surányi, 1997). In the study, 472 sour cherry cultivars were compared based on 7 relative ecological indicators and 3 biological values. Compared to other Prunus species, we mostly found less variability in sour cherries - not counting their salt tolerance (SB). The partial similarity between open pollination (OP), frost tolerance (FR) and disease resistance (DR) - partly true in terms of varieties, but also reflected the effects of purposeful breeding and selection. The cultivars together - in comparison, showed balance, but in the highlighting, the differences of the 3 cultivar groups became significant. Indeed, the differences between the species of the former Hungarian cultural flora are clearly different (Surányi, 2004), which is also the case when comparing a large number of apricot (Surányi, 2014), plum (Surányi, 2015) and peach (Surányi, 2020) varieties.

Over the last decade, the paradigm of acute renal injury has been changed fundamentally. Unfortunately, the routine clinical practice in Ukraine demonstrates extremely unsatisfactory awareness of the medical community on these issues. In this regard, the Expert Group of the Ukrainian Association of Nephrologists and Kidney Transplant Specialists has created the Adapted Clinical Guidelines on this important issue to improve the professional expertise of doctors, awareness of patients and their families.
Chronic kidney disease in children in Ukraine
Authors: Fomina S. P.
Published: August 2021

The study aimed to summarize data of Chronic Kidney Disease (CKD) in children and adolescents in Ukraine.

Methods. There were performed a qualitative study based on published documents and registers, and a cohort observational study included 3528 depersonalized patients with CKD diagnosed before the age of 18. That was used cross-sectional and longitudinal design for the structure, etiology, and outcomes analysis, period comparison (years 2014 and 2019), quantitative analyzes depending on patients age and nosology, risk measurements and survival function.

Results. There was found the tendency to reduce the incidence of the genitourinary system diseases in childhood, and the predominance of these classes of diseases in adolescents. The main causes of CKD were congenital structural or histological abnormalities and glomerulonephritis. Prolonged kidney function preservation at the initial level was confirmed in many patients (CKD1 was maintained in 33.0% and CKD5 - in 56.6% causes after 5 years period) with the partial function improvement in CKD1-3. CKD1-4 probability at the 1st year of observation was 91.7±0.47%, at the 5th year - 84.2±0.82%. The structural CKD5 specialties in patients receiving Kidney Replacement Therapy have been established. There was a significantly higher risk of CKD5 during 5 years period after Acute Kidney Injury (OR 2.81-2.10), and a lower probability of CKD5 in patients with glomerulonephritis (OR 0.66-0.54) compared to other nosology. CKD pathomorphosis was found in the year 2019 compared to the year 2014: the kidney dysplasia as an etiological factor was increased (from 19.3% to 22.0%, р=0.040); the immediate outcome at the 1st year of observation was improved with the lower risk of declaring of Glomerular Filtration Rate (GFR) to CKD5 level (93.6% vs. 90.0%), but the late follow-up prognosis became worse (the cumulative probability of CKD1-4 at the 5th year of observation decreased from 85.5 to 73.9%, p=0.016); the structure of Kidney Replacement Therapy changed with the increasing part of transplanted patients (from 30.5% to 48.9%, p<0.001), especially as a first choice (pre-dialysis); the tendency to decrease the proportion of polycystic kidney disease in CKD and to increase it in CKD5 was revealed with risk raising of GFR loss <15 ml/min in the year 2019 compared to other nosology (OR 1.69, p=0.027).

Conclusions. The established epidemiological and clinical realities are important for determining the kidney disease outcome in children and adolescents, assessing the medical management of these patients, sharpening the priorities of pediatric nephrology, and emphasizing the significance of further studies with appropriate regulations.
Impact of COVID-19 pandemic on urology practice: A single-center experience
Authors: Baran Caner
Published: August 2021

The present study aimed to evaluate the impact of the Coronavirus disease (COVID-19) pandemic on the urology outpatient clinic and provide objective data for the allocation of the resources during the pandemic. 

Materials and methods. The patient records who were admitted to our Hospital Urology outpatient clinic during March 20th - May 29th, 2019, and March 20th - May 29th, 2020 has been evaluated and constituted two groups as Non-Pandemic Group and Pandemic Group according to application date. Groups have been compared according to demographic and cohort-specific variables.

Results. There has been a statistically significant difference between groups according to age, gender, admission, prescription, and hospitalization rates. During the pandemic period, we found that the rates of patient admission, frequency and the number of hospitalizations decreased, and the rate of prescribing increased. Also, we found that male patients aged 18-65 years were admitted more frequently during the pandemic period.

The analysis of the subgroups constituted according to diagnostic segmentation revealed that the patients with lower urinary tract symptoms and pediatric urology patients decreased while infertility and infection groups were increased. 

Conclusion. The urology outpatient clinic has been affected by the COVID-19 pandemic from various perspectives. This alteration should take into consideration for the planning of the services during a pandemic.
Pediatric chronic kidney disease: Manifestations and evaluation
Authors: Ibrahim Olayinka Rasheed , Alao Michael Abel
Published: August 2021

Chronic kidney disease (CKD) is unique in children due to varying etiology, manifestation, and impact. Whereas it is far a lesser burden compared with adult CKD, childhood CKD has a psychosocial impact on caregivers, impair growth, quality of life, and ultimately associated with increased mortality. We summarize the manifestation, diagnosis, and evaluation of a child with CKD, whose early detection, and appropriate management will improve their outcome. Thus, we hope this will be valuable to the general medical practitioners, and pediatricians in the care of children with CKD.
