La obesidad infantil: análisis de los hábitos alimentarios y actividad física
Authors: Gordillo Gordillo María Dolores , Sánchez Herrera Susana , Bermejo García Maria Luisa
Published: July 2019

La Organización Mundial de la Salud (OMS) ha llegado a considerar la obesidad como “la epidemia del siglo XXI”, por el alcance adquirido y su impacto sobre la morbilidad, la calidad de vida y el gasto sanitario. Según la OMS, España es uno de los países de la UE con mayor prevalencia de sobrepeso y obesidad; afecta al 56% de los adultos y alrededor del 40% de los niños y adolescentes; desafortunadamente la región extremeña presenta índices de sobrepeso y obesidad por encima de la media nacional. El número de niños y adolescentes de edades comprendidas entre los cinco y los 19 años que presentan obesidad se ha multiplicado por 10 en el mundo en los cuatro últimos decenios. Las conclusiones de un nuevo estudio dirigido por el Imperial College de Londres y la Organización Mundial de la Salud (OMS) indican que, si se mantienen las tendencias actuales, en 2022 habrá más población infantil y adolescente con obesidad que con insuficiencia ponderal moderada o grave. Existe un cierto desconocimiento sobre lo que es una alimentación saludable, sin embargo, aumenta cada día más la preocupación de la población por la nutrición y la relación nutrición-salud.En este estudio nos planteamos hacer una evaluación desde la escuela para conocer los hábitos alimenticios y las rutinas de actividad física promovidas para los niños desde la etapa de educación infantil y comprobar los resultados antes y después del desarrollo de un programa de intervención.
El fantasma del control y los celos: violencia de género durante el noviazgo
Authors: Marcos Santiago Mariola , Isidro de Pedro Ana Isabel
Published: July 2019

Es indiscutible que la violencia de género continúa siendo una lacra social. Y, aunque es evidente el incremento de visibilidad y la sensibilización social al respecto, todavía es necesaria una gran labor de concienciación en igualdad y respeto hacia la mujer. En este sentido, el avance acelerado de las nuevas tecnologías, la generalización de su uso cotidiano y su elevado impacto social han brindado otras formas de comunicarse y de relacionarse, pero también han posibilitado nuevas manifestaciones de violencia de género, especialmente en parejas de adolescentes y jóvenes. Así, las nuevas formas de violencia de género durante el noviazgo, los mitos románticos y los estereotipos de género demandan un nuevo rumbo hacia líneas de investigación adaptadas a los tiempos. En el presente trabajo se pretende analizar, mediante una metodología cuantitativa, empírico-analítica, la violencia de género durante el noviazgo y la relación de ésta con las nuevas tecnologías, centrándonos en las cogniciones, vivencias y conductas experimentadas por las mujeres en tal sentido.Para ello, se utilizó un cuestionario de elaboración propia, conformado por preguntas cerradas de opción múltiple y preguntas tipo Likert, que fue aplicado a una muestra de 141 mujeres. Los resultados revelan que, en la muestra analizada, el grado de información y de conocimiento efectivo del fenómeno es más bajo del deseado. Por su parte, casi un tercio de las mujeres reconoce que su novio es celoso y posesivo. Un porcentaje similar afirma que su novio tiene sus contraseñas de móvil, aunque en menor medida asumen que él controla sus redes sociales y su dispositivo móvil. También son relevantes los comentarios y bromas sarcásticos de carácter celotípico hacia ellas por parte de sus parejas y las acusaciones de infidelidad o de coquetear con otros. Por último, se proponen unas breves líneas de actuación socioeducativa.

Authors: Lope Álvarez Ángela , Antoñanzas Laborda José Luis
Published: July 2019

La familia es un pilar fundamental en el desarrollo de la personalidad en niños y adolescentes. Es la familia la que tiene un papel primordial a la hora de motivar a sus hijos ya sea dando apoyo ante las adversidades del día a día o simplemente ayudándoles a hacer los deberes. Por este motivo, se ha tomado como variable principal la satisfacción familiar de la que se desprenden posteriormente otras variables como la autoestima o la satisfacción con los resultados obtenidos durante el curso, entre otras. Los resultados o la satisfacción del niño con sus resultados dependen de su situación en casa, de si se enfrenta solo a los problemas o si por el contrario se siente apoyado y escuchado. Este estudio pretende demostrar la importancia que tiene la familia en el niño o adolescente además de evaluar otras variables que pueden verse afectadas por una satisfacción familiar inadecuada.
Mujeres en la universidad española: diferencias de género en el alumnado de grado
Authors: Gómez Marcos Maria Teresa , Vicente Galindo María Purificación , Martín Rodero Helena
Published: July 2019

La primera matrícula femenina en la universidad española tiene lugar en el año 1872 cuando María Elena Maseras Ribera accede a la Facultad de Medicina de la Universidad de Barcelona. Desde entonces, el número de alumnas ha ido en aumento y su acceso a diferentes disciplinas ha variado según las circunstancias sociales de cada época, siempre teniendo como referencia una formación que no las aparte del modelo doméstico.La presente investigación identifica las especialidades de la educación superior que no presentan una distribución de género equitativa. Para su desarrollo, se han seleccionado los alumnos de Grado matriculados en las universidades españolas en los tres últimos cursos académicos. Los resultados indican que existen diferencias de género estadísticamente significativas en algunos ámbitos de estudio. La mayor presencia de mujeres se circunscribe a carreras consideradas tradicionalmente por la sociedad acordes a su papel en el ámbito familiar. Por el contrario, las titulaciones relacionadas con la técnica –más cercanas a los estereotipos masculinos-, siguen reflejando en la actualidad una participación femenina minoritaria.
Niveles de burnout en docentes de secundaria: un estudio descriptivo analítico
Authors: Vicente de Vera García M. Inmaculada , Gabari Gambarte M. Inés
Published: July 2019

El profesorado es especialmente vulnerable a desarrollar el síndrome de burnout debido a los componentes afectivos y emocionales inherentes al perfil profesional. La incidencia es más elevada en quienes trabajan en la etapa de enseñanza secundaria obligatoria (12-16a) y postobligatoria (16- 18a), con población adolescente, dado el momento de cambios vitales del alumnado y la exposición intensa a intereses sociales por un lado y, por otro, a la idiosincrasia organizativa de los centros educativos y a las demandas y presiones académicas que conlleva el inminente acceso al mundo laboral o formativo a la Enseñanza Superior. El objetivo del estudio es medir e interpretar la vivencia de burnout en los docentes participantes. Se trata de un diseño transversal descriptivo. La muestra invitada está compuesta por el profesorado de Educación Secundaria de los 24 Institutos de la provincia de Huesca (N=1.268) pertenecientes a la red pública de enseñanza en el curso 2014/15, la participación voluntaria conforma una muestra aceptante de n=167 docentes (13,17%). Para la medida del burnout se emplea la adaptación al castellano del (MBI-GS) de Salanova, Schaufeli, Llorens, Peiró y Grau (2000), mediante encuesta on-line. Los resultados indican que el profesorado participante presenta bajos índices de burnout (1,20%), con agotamiento y cinismo elevados y eficacia baja. Cabe pensar en una subdeclaración que precisaría estudios complementarios.
Library and Information Science Curriculum in a Changing Professional Landscape: The Case of Copyright Education in the United States
Authors: Kawooya Dick , Ferullo Donna , Lipinski Tomas
Published: July 2019

Despite the importance placed on copyright and intellectual property literacy by the American Library Association, as evidenced in the accreditation standards, issues pertaining to copyright education remain marginal in the library and information science (LIS) curriculum and research. Today, copyright intersects with every library and information service in any type of information institution, yet few librarians get copyright training as part of the formal LIS curriculum in library schools. Lack of copyright education leaves many librarians unable to properly identify and address copyright issues in the workplace. This paper offers a critical analysis of LIS programs over the past 10–12 years with a specific focus on trends in the teaching of copyright matters. Employing a qualitative methodology with a mixed-method approach, the authors analyzed the syllabi of courses dedicated to copyright and intellectual property offered at select LIS programs. The goal was to understand what the copyright courses cover, how they are taught, instructional sources and resources, and curriculum changes over time, where applicable. Findings show that the few LIS programs offering copyright courses have rigorous and dynamic copyright curriculum that constantly changes with the evolving copyright environment. The main takeaway and recommendation is that some kind of coordination is needed in the teaching of copyright and that LIS programs may need minimum standards for the core curriculum of copyright courses. The coordinating mechanism will ensure that periodic review of the core curriculum occurs and takes into account the rapid changes in the different library environments where library students work.

Las variables tamaño, edad franquicia y regalías mostraron mayor poder discriminante para la adopción de prácticas de RSE en el sector alimentos; la cuota de entrada, la edad franquicia y porcentaje, en el sector comercio. Solamente la variable cuota de entrada mostró poder discriminante en el sector servicios especializados.
Calibration Protocol - OD600 Inter-equipment Conversion with LUDOX v3
Authors: Rutten Paul , Tennant Richard , Beal Jacob , Workman Christopher , Haddock-Angelli Traci , Farny Natalie , Selvarajah Vinoo
Published: July 2019

With this protocol you will use LUDOX CL-X (a 45% colloidal silica suspension) as a single point reference to obtain a conversion factor to transform absorbance (OD600) data from your plate reader into a comparable OD600 measurement as would be obtained in a spectrophotometer. This conversion is necessary because plate reader measurements of absorbance are volume dependent; the depth of the fluid in the well defines the path length of the light passing through the sample, which can vary slightly from well to well. In a standard spectrophotometer, the path length is fixed and is defined by the width of the cuvette, which is constant. Therefore this conversion calculation can transform OD600 measurements from a plate reader (i.e. absorbance at 600 nm, the basic output of most instruments) into comparable OD600 measurements. The LUDOX solution is only weakly scattering and so will give a low absorbance value. Protocol based on this Yeast Plate Count Protocol.

Published: July 2019

This procedure can be used to calibrate OD600 to colony forming unit (CFU) counts, which are directly relatable to the cell concentration of the culture, i.e. viable cell counts per mL. This protocol assumes that 1 bacterial cell will give rise to 1 colony. For the CFU protocol, you will need to count colonies for your two Positive Control (BBa_I20270) cultures and your two Negative Control (BBa_R0040) cultures.

Prevalence and pattern of anaemia and correlation with booking status in a new Medical College in Haryana, India
Authors: Kashyap Anshika , Bano Tabassum , Babar Nadia
Published: July 2019

Background: Anaemia is the commonest medical disorder in pregnancy. It is a leading cause of maternal morbidity and mortality.  This study analyses the   prevalence and pattern of anaemia and correlates it with booking status in a   new medical college in rural Haryana.Methods: This retrospective study was conducted to analyze prevalence, severity and morphology of anaemia in hospitalized pregnant patients at the time of labour in a new medical college in rural Haryana.  Antenatal booking status was correlated with haemoglobin levels and severity. The study was conducted over a period of six months from Nov ’18 to April’19.Results: 390 singleton labour patients at or near term with no other known medical complications were evaluated. Prevalence of anaemia in the centre serving as a referral with onsite blood bank facilities was as high as 79.7 %. 47.9%   of patients did not have even a single antenatal visit. 50.8% had microcytic hypochromic anaemia followed by 32.3% who had normal morphological picture; dimorphic was 14% and macrocytic 2.8%. The prevalence in booked patients was 78.91% compared to 80.1% in unbooked.Conclusions: Anaemia continues to be a major challenge to the obstetric services despite targeted efforts by the government and various organizations to provide free prophylaxis. Iron deficiency or nutritional anaemia is the commonest.  However, booking visits, counselling and free distribution of iron tablets doesn’t ensure that the patient is protected from anaemia. This raises concerns about compliance and hence effectiveness of oral iron therapy. An aggressive strategy for diagnosis, prophylaxis and treatment of anaemia as well as a method to ensure compliance must be developed.

Published: July 2019

Background: Secondary hyperparathyroidism is known and early complication of chronic renal failure patients. Aim of this study was to assess the prevalence of secondary hyperparathyroidism and correlation between serum parathyroid hormone level with biochemical parameters in renal failure patients in tertiary care hospital in Kota, Rajasthan.Methods: A cross sectional observational study was carried out in 50 patients who had creatinine clearance of 30ml/min/1.73m2 or less for greater than 6 weeks attended the OPD of department of General Medicine, New Medical College hospital, Kota, Rajasthan from May 2018 to November 2018. Investigations like complete blood count, renal function test, urine routine microscopy and USG abdomen with serum parathyroid hormone, serum phosphorus, serum calcium levels were done. Serum parathyroid hormone level was done by calorimetric method.Results: The prevalence of secondary hyperparathyroidism in our study was 72%.In hyperparathyroidism patient’s serum calcium level was low and the difference was highly significant (p<0.001). There is negative correlation between S.PTH and S. calcium level (r=-0.536). Mean serum calcium level in our study is 1.6mmol/l. In hyperparathyroidism patient’s serum phosphate level was high and the difference was highly significant (p<0.001). There was positive correlation between S.PTH and S.PO4 level (r=0.402). Mean serum phosphorus level in our study is 5.7 mg/dl. Prevalence of hyperparathyroidism was high among CRF patients with normal BP than hypertensive patients and with normal sugar than diabetics but the difference in proportion was not significant (p=0.87, p=0.98 respectively). 90% patients were on haemodialysis while 10% patients were on conservative management.Conclusions: Early detection of secondary hyperparathyroidism in chronic renal failure patients can reduce its complications like bone fracture and cardiovascular complications.

Published: July 2019

Background: In order to perform laparoscopic procedures, it is necessary to first access the peritoneal cavity and establish carbon dioxide pneumoperitoneum. The placement of the first trocar remains a critical step in laparoscopic surgery. In order to minimize complications associated with placement of first trocar, several techniques have been reported. Author describe a surgical technique that provides a quick, safe, and reliable initial access to the peritoneal cavity with its excellent functional and cosmetic results.Methods: Retrospective study of patients who underwent various laparoscopic procedures at Maxx lyfe Hospital, Bathindi, Jammu was carried out by the closed technique for initial access to the peritoneal cavity through the umbilicus from July 2016 to May 2019. In this study, patients who had a prior midline laparotomy with involvement of the umbilicus were excluded.Results: Authors analyzed 456 patients (M = 190; F = 266) in the study period. Average age of the patients was 32 years (range:12-86). A physiologic defect was identified in the umbilical region in all patients who had no history of previous abdominal surgery in that region. The average time to access the peritoneal cavity was 30 seconds (range: 20-50).Conclusions: This technique is quick, safe, reliable, simple, and easy to learn and easy to perform. It is associated with no mortality and minimal morbidity and has excellent cosmetic results. Based on authors experience, authors believe that this method provides surgeons with an effective and safe way to insert the first trocar and recommend it as a routine procedure to access the peritoneal cavity for abdominal laparoscopic surgery.

Colorectal cancer (CRC) is the third most common type of cancer worldwide, currently representing the most common gastrointestinal cancer with 13% of all malignant tumors. MicroRNAs (miRNAs) are small non-coding RNAs that repress the translation of target genes. Since their discovery, they have been shown to play an important role in the development of cancer, since they can act as tumor suppressors or oncogenes. A literature review was performed in different databases such as Medline, PubMed, Cochrane, nature, Wolters Kluwer, ScienceDirect, Scopus, SpringerLink, Wiley Online Library. Studies were included from 2003 to 2018. Colorectal cancer presents genetic heterogeneity, because it can develop in different ways, the pathway through which cancer occurs depends on the gene initially altered. The aberrant expression of microRNAs is implicated in the development of colorectal cancer and its progression. Three existing steps in the maturation of the microRNAs have been identified: 1) transcription of the pri-miRNA, 2) cleavage in the nucleus to form the pre-miRNA and 3) a final excision in the cytoplasm to form the mature microRNA. It has been discovered that miRNAs have an impact on cell proliferation, apoptosis, stress response, maintenance of stem cell potency and metabolism, all important factors in the etiology of cancer. The data analyzed in this article highlights the importance of the study of microRNAs in colorectal cancer, however, for the carcinogenic process, progression, therapeutic management and prognosis, more multicenter randomized clinical trials are needed with a detailed analysis.

Published: July 2019

Background: To know the various causes of lymphadenopathy in children and to know the usefulness of FNAC in diagnosis of various causes of lymphadenopathy.Methods: Children less than 12 years with significant lymphadenopathy (lymphadenopathy of >1 cm in cervical, axillary and >1.5 cm in inguinal region) were included.Results: A total of 50 children were enrolled in the study. The incidence of lymphadenopathy was more common in the age group of 4-8 year during the lymphoid phase with male preponderance of all the causes infections especially tuberculosis was the major cause of lymphadenopathy which is totally preventable by giving BCG vaccination. The sensitivity of FNAC in the present study was 71.3%. In 3 cases FNAC 69 was not done because peripheral smear examination revealed that the patients are suffering from acute lymphoblastic leukemia.Conclusions: FNAC is a simple bed side investigation though traumatic is of immense value for diagnosing various cases. Even though it may not be a replacement for lymphnode biopsy, it is preferred as a first line investigation because of its simple procedure.

Published: July 2019

Background & Aim: Delirium is prevalent in the intensive care unit, especially among mechanically-ventilated patients. Delirium is associated with a significant increase in adverse outcomes but it usually remains undiagnosed, making it necessary to develop and validate diagnostic tools. This study determined the validity and reliability of the Persian version of the Confusion Assessment Method for Intensive Care Units in Iran.
Methods & Materials: This cross-sectional study was conducted in open-heart intensive care unit of three university hospitals of Tehran, Iran. After piloting the translated confusion assessment method for intensive care units on 10 patients and refining the translated scale accordingly, 40 ventilated patients were consecutively selected and screened for delirium by two independent evaluators, and one psychiatrist. Inter-rater reliability between the two evaluators was assessed by the Kappa coefficient. Validity indices (i.e., sensitivity and specificity) of the Persian-CAM-ICU and 95% confidence intervals were calculated, given the psychiatrists’ diagnosis as the reference standard. Data were analyzed in Stata software (v. 11).
Results: Of 40 selected patients, CAM-ICU detected delirium in 30%. The Persian-CAM-ICU had a sensitivity and specificity of 75% and 96%, and a positive and negative predictive value of 92% and 85%, respectively. Youden’s J statistic of the scale was 71%. Each of the four domains of the CAM-ICU showed a sensitivity and specificity of more than 69% and 90%, respectively, suggesting acceptable construct validity. There was good agreement between the two evaluators in terms of delirium diagnosis with the Persian-CAM-ICU (kappa coefficient = 0.74, P<0.0001).
Conclusion: The Persian version of the CAM_ICU is an effective, valid and reliable diagnostic tool in critically ill ICU patients. Application of the scale is recommended for the prompt diagnosis and prevent potential delirium in ventilated patients.

Strategies to Deal with Ground Faults in Grid-Connected Transformerless Photovoltaic Converters with Battery Energy Storage System
Authors: Bellinaso Lucas V. , Figueredo Ricardo S. , Almeida Marcelo P. , Bortolini Ricardo J. F. , Bet Ildo , Michels Leandro , Zilles Roberto
Published: July 2019

Grid-connected photovoltaic systems with energy storage, also called PV hybrid mini-grid system (PVHMS), operate in both grid-tied and stand-alone modes and are expected to play an important role in distributed generation. Transformerless photovoltaic converters are most preferred for these systems due to their higher conversion efficiency in comparison to insulated converters, increasing autonomy of the battery energy storage system (BESS). Safety in transformerless photovoltaic converters is a critical issue due to parasitic capacitance between PV modules and ground that could result in high leakage current. Existing safety requirements for grid-tied PV inverters may not be sufficient for PVHMS converters since they have multiple leakage current paths. This study analyzes some leakage-current-related faults on transformerless PVHMS converters, and proposes relay opening sequences to avoid unnecessary interruptions of power supply for the local loads. The following situations are analyzed: i) fault at dc side, ii) fault at ac load side, and iii) commutation between on-grid and off-grid operation modes. These faults have been studied for a transformerless PVHMS converter with a single dc-ac stage. Experimental results are presented to validate the proposed schemes and a table summarizing the proposals is presented.

Authors: Aleksandrov A.A. , Barmin I.V. , Pavlov S.K. , Chugunkov V.V.
Published: July 2019

The paper focuses on hydrocarbon fuel cooling in launch vehicles, specifically considering experimental technique and results obtained during investigation of one of the primary heat exchanger parameters, that is, heat transfer coefficient of the heat exchanger surface. We present a model of efficient hydrocarbon fuel cooling by means of intensifying heat transfer on the external heat exchanger surface due to nitrogen sparging causing active motion in the liquid heat carrier. We obtained quantitative data regarding heat transfer on the external surface of a helical-coil heat exchanger located in a two-phase medium consisting of antifreeze and nitrogen, in the temperature range of 243--293 K. We derived a similarity equation for calculating heat transfer coefficient on the external heat exchanger surface, which is required to determine the heat exchanger surface area and to compute heat transfer from hydrocarbon fuel to the two-phase medium consisting of antifreeze and nitroge.

The paper considers the possibility of monitoring reliability of infrared spectroradiometer operation when detecting the presence of a toxic chemical in a dusty atmosphere. We present a method for estimating cumulative concentration of aerosol particles based on evaluating variations in contrast of a test object against the background in the visible wavelength range during gas and aerosol cloud propagation. In order to determine the critical contrast value that corresponds to the aerosol concentration designating further inability of the spectroradiometer to detect the toxic chemical in the air, we propose to numerically solve the problem of radiation transfer in a medium with known parameters. We report the results of solving this problem for an interfering aerosol consisting of water droplets with a diameter of 5--20 µm. We show that for a signal-to-noise ratio of 100 it is possible to detect a toxic chemical at aerosol concentrations of up to 5 g/m2. Implementing the method proposed involves using a video camera to monitor the test object and a computer to process the images recorded.
Oscillation Problem for an I-Beam with Fixed and Hinged End Supports
Authors: Rudakov I.A.
Published: July 2019

The paper investigates the problem concerning time-periodic solutions to a quasi-linear equation describing forced oscillations of an I-beam with fixed and hinged end supports. The non-linear term and the right side of the equation are time-periodic functions. We seek a Fourier series solution to the equation. In order to construct an orthonormal system, we studied the eigenvalue problem for a differential operator representing the original equation. We estimated the roots of the respective transcendental equation while investigating eigenvalue asymptotic of this problem. We derived conditions under which the differential operator kernel is finite-dimensional and the inverse operator is completely continuous over the complement to the kernel. We prove a lemma on existence and regularity of solutions to the respective linear problem. The regularity proof involved studying the sums of Fourier series. We prove a theorem on existence and regularity of a periodic solution when the non-linear term satisfies a non-resonance condition at infinity. The proof included prior estimation of solutions to the respective operator equation and made use of the Leray --- Schauder fixed point theorem. We determine additional conditions under which the periodic solution found via the main theorem is a singular solution.

Published: July 2019

The peculiarities of spin-polarized electronic structure of multilayer graphene nanofilm (4-GNL:H) within the framework of Kohn --- Sham approximation were studied in the present work. The calculated band structure and spin-resolved electronic energy spectrum of the 4-GNL:H system were correlated with experimental UPS and XANES spectra of thin hydrogenated a-C:H films. As the band structure calculations show there is a dimensional quantization of energy spectrum in the 4-GNL:H system, and the energy gap of 0.11 eV appears in the spectrum. The self-consistent calculations also predict the existence of itinerant magnetism in the system, conditioned by hydrogen chemisorption.

Published: July 2019

Manufacturing processes in the electroplating industry employ hazardous chemicals and generate hazardous waste, including hexavalent chromium compounds and heavy metal cyanides. We designed a reagent-based treatment technology that can remove these contaminants and is relatively simple to implement and maintain. The technology features low reagent consumption but high treatment efficiency and simplifies separating precipitates from the treated effluent. The paper presents a detailed description of how to neutralise electroplating shop wastewater. We propose a system of organizational and technological measures to improve chemical safety.
Researches the Process of Formation Salicylaldoxime the Condensation of Salicylaldehyde and Hydroxylamine Sulfate with a Polarographic Control
Authors: Saitova N.G. , Novikov V.T.
Published: July 2019

The use of the polarographic method allows us to trace the condensation of salicylicaldehyde with hydroxylamine sulfate, which results in salicylaldoxime formation. This makes it possible to reduce salicylaldoxime losses occurring as a result of its hydrolysis in the course of salicylamine electrosynthesis, by reduction of salicyloxime forming in the course of salicylicaldehyde and hydroxylamine sulfate condensation. It was found that the rate of salicylic aldehyde and hydroxylamine interaction is high. Salicylicaldehyde completely reacts with hydroxylamine when their molar ratio is equal to 1:5, and salicyloxime is formed with quantitatively yield under these conditions.
New Quantum Chemical Method for Assessing the Relative Activity of Antioxidants
Authors: Yarkova T.A. , Gyulmaliev A.M.
Published: July 2019

A new method for evaluating the antioxidant activity of organic compounds based on quantum chemical calculations of their electronic structure using the DFT B3LYP/6-31G (d, p) method has been proposed. The geometric parameters of antioxidant molecules were optimized and the reactivity indices were determined from the energy values of the highest occupied and the lowest unoccupied molecular orbitals: absolute electronegativity; electronic chemical potential; absolute "chemical hardness". The found indicators allow us to quantify the antioxidant activity by building their dependence on the energy of the lower vacant molecular orbitals. The correlation of the obtained parameters with the standard, such as trolox, allows determining the relative antioxidant activity of the test substance.

THE EFFECTS OF EQUITY-FINANCED LONG-TERM ASSETS ON LIQUIDITY IN THE AGRICULTURE SECTOR OF TURKEY
Authors: AÇIKGÖZ Ali Faruk , DEMİRKOL Celal , TAÇ Umut
Published: July 2019

This study aims to conduct a typical regression
methodology on the long-term data of the agriculture sector in Turkey. The regressive
model represents current ratio as the dependent variable, and it uses the
ratios of short-term liabilities on total liabilities, bank credits payable in
the short-term on short-term liabilities, bank credits payable in the long-term
on total assets, and long-term assets on (shareholders’) equities as the
independent variables. The tests are executed by using the averages of
aggregate totals of the businesses from all scales in the sector in three years’
averages from 1998 until 2016. The findings statistically ensure and depict
that the framework indicator of liquidity or the famous current ratio depends
not only on the bank credit used or the level of short-term liabilities, which
is not surprising, but also on the ratio of long-term assets on equities. If
the businesses enrich their equities level in financing of long-term assets,
the liquidity favors. The independent variable of long-term assets to equities
ratio, which rather reflects the long-term movement of current ratio better
than the other variables, deeply affects the level of better liquidity as
significantly as other control variables of the study. As a conclusion, better
liquidity could profoundly be a lagging result of better equity-type financing
of the total assets. The outcomes of the study will expectedly signal the
decisions and policies of agriculture sector in Turkey by the long-term
evidence presented here.

ihtiyaçlarını en üst düzeyde karşılayabilmeleri ve günümüzün gittikçe zorlaşan
pazar koşullarında başarılı stratejiler geliştirebilmeleri için tüketicileri yakından
tanımaları gerekmektedir. Özgüven ile marka beğenilirliği arasındaki ilişkinin
anlaşılması, tüketicilerin marka ile olan ilişkilerinin ve markayı
değerlendirme şekillerinin tespiti açısından önem taşımaktadır. Bu doğrultuda
mevcut çalışma, hedef pazarın önemli bir kısmını oluşturan kadın tüketicilerin,
demografik özellikleri ile özgüvenleri ve marka beğenilirliği arasındaki
ilişkiyi araştırmak amacıyla yapılmıştır. Bu amaç doğrultusunda toplam 402
