The purpose of the study was to analyse and evaluate the institutionalization of the agricultural market in Ukraine and the European Economic Community. The authors conducted a study devoted to the analysis of the regulatory and legal framework in the field of market economy building and state regulation of the agricultural market in Ukraine during the 1990s - 2020s. It is substantiated that the shortcomings of market reforms and dysfunctions of the agrarian market due to lack of scientific understanding of the role of the factor of normative and legislative support of the processes of market reforms in general, the formation of sectoral markets, as well as their effective functioning by the criterion of timely response to dysfunctions. The study was based on systematic and benchmarking methods. The tasks of the study were solved using such methods as: systematic, historical, deductive, inductive, analysis and synthesis, statistical and comparative analysis. The theoretical provisions of institutional theory in the context of the formalization of the agrarian market institute in Ukraine and the European Economic Union and proved the need to follow the logical coherence and complexity of its institutional support as a necessary element of market reforms in the study has further developed. A model of the process of institutional support of market reforms in Ukraine is proposed. The final stage of the institutionalization of the agrarian market in Ukraine is the achievement of conditions of equivalent market exchange.

Abstract
This paper investigates the potential of polymer optical fiber (POF) in pavement crack monitoring. Firstly, the critical radius of macrobending and microbending of POF was analyzed theoretically. Then, the relationship between the bending loss and the bending radius was established and verified by experiments, and a reasonable bending radius was recommended. Subsequently, the POF was fixed on a simulated pavement with various fiber-crack angles, and the effect of fiber-crack angles on light loss was analyzed. The results showed that the optical loss decreased exponentially with the increase of the bending radius when the bending radius was less than 8 mm, but it changed slowly when the bending radius was more than 8 mm. The output optical power value was related to the initial fiber-crack angle and the bending radius. Under the same bending radius, the optical loss became greater if the initial fiber-crack angle was smaller.

Authors: Wanduku Divine , Oluyede B.O. 
Published: May 2020

This paper presents the dynamics of mosquitoes and humans with general nonlinear incidence rate and multiple distributed delays for the disease. The model is a SEIRS system of delay differential equations. The normalized dimensionless version is derived; analytical techniques are applied to find conditions for deterministic extinction and permanence of disease. The BRN R0* and ESPR E(e–(μvT1+μT2)) are computed. Conditions for deterministic extinction and permanence are expressed in terms of R0* and E(e–(μvT1+μT2)) and applied to a P. vivax malaria scenario. Numerical results are given.

OBJECTIVES:Prescription of opioids to treat pediatric migraine is explicitly discouraged by treatment guidelines but persists in some clinical settings. We sought to describe rates of opioid administration in pediatric migraine hospitalizations.METHODS:Using data from the Pediatric Health Information System, we performed a cross-sectional study to investigate the prevalence and predictors of opioid administration for children aged 7 to 21 years who were hospitalized for migraine between January 1, 2016, and December 31, 2018.RESULTS:There were 6632 pediatric migraine hospitalizations at 50 hospitals during the study period, of which 448 (7%) had an opioid administered during the hospitalization. There were higher adjusted odds of opioid administration in hospitalizations for non-Hispanic black (adjusted odds ratio [aOR], 1.68; P &lt; .001) and Hispanic (aOR, 1.54; P = .005) (reference white) race and ethnicity, among older age groups (18–21 years: aOR, 2.74; P &lt; .001; reference, 7–10 years), and among patients with higher illness severity (aOR, 2.58; P &lt; .001). Hospitalizations during which an opioid was administered had a longer length of stay (adjusted rate ratio, 1.48; P &lt; .001) and higher 30-day readmission rate (aOR, 1.96; P &lt; .001). By pediatric hospital, opioid administration ranged from 0% to 23.5% of migraine hospitalizations. Hospitals with higher opioid administration rates demonstrated higher adjusted readmission rates (P &lt; .001) and higher adjusted rates of return emergency department visits (P = .026).CONCLUSIONS:Opioids continue to be used during pediatric migraine hospitalizations and are associated with longer lengths of stay and readmissions. These findings reveal important opportunities to improve adherence to migraine treatment guidelines and minimize unnecessary opioid exposure, with the potential to improve hospital discharge outcomes.
Circuitos punitivos: limitaciones del <i>populismo penal</i> a partir de las prácticas de criminalización de mujeres trans y travestis en una <i>zona roja</i> argentina
Authors: Lascano Aramis , Vélez Joaquín 
Published: May 2020

This article analyses transgender women and transvestites’ criminalization practices in a red-light district, from two investigations located in La Plata city, Argentina. In order to achieve this proposal, we apply urban and action research tools to analyze security ensembles between different state agencies and neighborhood groups, so that the ways in which such practices are legitimized and become possible can be addressed. The daily regulation of inhabited spaces allows us to visualize disputes over the forms of appropriation, and to historicize social control of the supply of sex in the public space. Under this casuistry, we question limitations of the notion of punitive populism. We propose the figure of punitive circuits to visualize the territorial specificities linked to the insecurity that moral and criminal control practices have over the red-light district, and the multiplicity of people and agencies that intervene in its course.

Published: May 2020

Carbon monoxide is a flammable gas and very toxic to humans, to determine the concentration of carbon monoxide (CO) gas requires a tool that can measure the concentration of the gas. The design of the CO gas monitoring measuring instrument in this study has dimensions of 11cm x 8.6 cm x 2.9 cm using the MQ-135 sensor, Arduino Uno microcontroller to control and process the signal, to display temperature and humidity with a 4.2 Inch LCD. Krisbow KD09-224 Carbon Monoxide Meter is a comparison tool or calibrator, against our monitoring gauges. Testing by experimenting as much as 15 times, to determine the value of the measurement uncertainty. Based on the results of the data when testing, the average amount of measurement = 103.33, with a standard deviation δ 1.29, and the uncertainty value of the measurement results is 0,33 %. Thus the system can be used as monitoring of CO gas pollution in units of ppm (parts per million).

A thin layer of Barium Strontium Titanate Ba0.15Sr0.85TiO3 (BST) was developed on a glass substrate using a sol-gel method with annealing temperatures and spin coating process at 3500 rpm for 30 seconds. The annealing temperature varied from 600oC, 650oC, and 700oC. Characterization of optical properties was developed using UV-Vis spectroscopy to determine the energy bandgap. The values of the BST thin layer energy band at the annealing temperature were 3.55 eV, 3.32 eV, and 3.10 eV, respectively. The results indicate that the BST thin film was a semiconductor material.

Abstract
Background: It has been substantiated by Genome-wide association studies (GWAS) that genetic disparity influences the fat levels and obesity risk in various populations.Objective: A meta-analysis of 15 genome-wide association studies identified regularly-used obesity-related variables at eight gene loci, inclusive of FTO, MC4R, TMEM18, KCTD15, GNPDA2, SH2B1, MTCH2 and NEGR1. However, the expression profiles of eight obesity-related genes remain largely unknown.Methods: Based on the fundamental propositions specified in the Declaration of Helsinki, adipose tissue specimens were collected from 23 obese and 16 normal weight subjects, and the expression profiles of eight obesity-related genes identified by GWAS were examined in these white adipose tissues (WAT). The effects of KCTD15 gene on adipocyte differentiation in mature 3T3-L1 adipocytes were assessed.Results: Among the obesity-related genes identified by GWAS, SH2B1, FTO, TMEM18 and KCTD15 were expressed at lower level in WAT of obese subjects compared to normal weight subjects, while NEGR1 showed a higher expression level in the obese subjects. No changes were detected for MTCH2, GNPDA2 and MC4R. The expression of KCTD15 was negatively correlated with Body mass index (BMI) and abdominal circumference. The siRNA-mediated knockdown of KCTD15 significantly suppressed cellular lipid accumulation during adipocyte differentiation.Conclusion: This is the first study to identify the expression patterns of eight obesity-related genes which is connected with adiposity in WAT of overweight people in China. Our study demonstrates that the expression of KCTD15 is associated with obesity in humans. Meanwhile, KCTD15 may play a critical role in the regulation of adipogenesis.

Abstract
Background: Individualized ablation is not only able to correct corneal low-order aberrations but also to improve corneal high-order aberrations in patients with corneal asymmetry. In this study, we compared the effects of three different surgical methods, namely, corneal wavefront-guided femtosecond laser assisted in-situ keratomileusis (CWFG-FS-LASIK), aberration-free femtosecond laser assisted in-situ keratomileusis (AF-FS-LASIK) and small incision lenticule (SMILE), in patients with mid-to-high astigmatism asymmetric corneas (1-4D).Methods: One hundred-fourteen eyes from 58 patients were enrolled in this retrospective study. We measured and compared the best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), residual astigmatism, total coma, vertical coma (Z3-1), horizontal coma (Z31), modulation transfer function (MTF) and point spread function (PSF) preoperatively and three months postoperatively. Results: The visual acuity of patients in the three groups was increased after surgery, but the improvements in visual acuity and residual astigmatism among them were not significantly different. However, the improvements in 4-mm and 6-mm total coma, Z3-1 and Z31 in patients who underwent CWFG-FS-LASIK were better than those in patients who underwent AF-FS-LASIK and SMILE. Consistent with these results, the improvements in MTF and PSF (3 mm and 5 mm) in the CWFG-FS-LASIK group were better than those in the AF-FS-LASIK and SMILE groups.Conclusions: Among surgeries for treating patients with mid-to-high astigmatism in asymmetric corneas, the selective coma-guided modality was able to decrease the coma of original cornea, improve visual acuity and optimize the visual quality of patients.

Published: May 2020

Abstract
BackgroundWe describe a transdisciplinary medical unit, referral center for the management of anorexia nervosa (AN) adult patients with extremely severe malnutrition.MethodHistory, organization and activity of the unit are described. Characteristics of all adult AN patients admitted for the first time in the unit between November 1997 and January 2014 and medical care provided are detailed, before discussing the value of such a unit.ResultsThe unit was established as an independent department in 2004 and has 180 to 200 admissions per year. The patients hospitalized in the department are clinically serious and unstable because of life-threatening somatic complications due to a low BMI (< 13 kg/m²). They are referred on criteria of somatic severity. They often had multiple hospitalizations in other acute care hospitals before being supported in the unit. Among a cohort of 386 adult AN patients admitted for the first time in the unit, mean age was 29.4 (± 11.5) years, mean BMI was 12.7 (± 2.2) kg/m² and 78.2% of patients had already been hospitalized in other hospitals.ConclusionThis specialized transdisciplinary unit where physician nutritionists and psychiatrists coordinate medical care together, allow a better understanding and management of extreme malnutrition associated with AN. Thanks to their expertise, care teams are less critical and less rejecting towards patients. Thus, therapeutic alliance is optimized.

Abstract

BackgroundBlunt trauma is a potentially life-threatening injury that requires prompt diagnostic examination and therapeutic intervention. Nevertheless, how impactful a rapid response time is on mortality or functional outcomes has not been well investigated. This study aimed to evaluate effects of earlier door-to-computed tomography time (D2CT) and door-to-bleeding control time (D2BC) on clinical outcomes in severe blunt trauma.MethodThis was a single-center, retrospective cohort study of patients with severe blunt trauma (Injury Severity Score > 16) treated between August 2007 and July 2015 in a tertiary trauma center in Japan. Patients who underwent whole-body CT scanning within 90 minutes of emergency room arrival were included. To assess the effect of earlier D2CT and D2BC on 28-day mortality, we conducted multivariable regression analyses with consideration of non-linear associations. The effects on 24-hour mortality and the Oxford Handicap Scale were also evaluated as secondary outcomes.ResultsAmong 671 patients with severe blunt trauma who underwent CT scanning, 163 patients received an emergency bleeding control procedure. The median D2CT and D2BC were 19 min (IQR 12–27) and 57 min (IQR 45–75), respectively. In a Cox proportional hazard regression model, earlier D2CT was not associated with improved 28-day mortality (p = 0.30), whereas earlier D2BC was significantly associated with improved 28-day mortality (p = 0.026). This beneficial trend of D2BC was consistently observed for the assessment of secondary outcomes.ConclusionAmong patients with severe blunt trauma undergoing CT scanning, time benefits were not observed for the CT examination itself but were for therapeutic bleeding control.
