Published: November 2021

BACKGROUND

Breastfeeding is an important determinant of early infant immune function and potentially future health. Although numerous studies have reported rising breastfeeding initiation rates and duration, few longitudinally investigated the impact of shifting societal and lifestyle factors on breastfeeding patterns in developed nations.

METHODS

The Ulm Birth Cohort Study (UBCS) and Ulm SPATZ Health Study (SPATZ) cohorts consist of newborns and their mothers recruited, respectively, from 2000 to 2001 and 2012 to 2013 at the University Medical Center Ulm, Germany. Cox proportional hazards models were used to estimate crude and mutually adjusted hazard ratios for study effect (time trend) and individual risk factors on noninitiation and duration of predominant and total breastfeeding.

RESULTS

Compared with UBCS mothers, SPATZ mothers had lower cessation rates of both predominant breastfeeding by 4 months and total breastfeeding by 6 months: hazard ratio (95% confidence interval) 0.79 (0.67–0.93) and 0.71 (0.60–0.82), respectively. However, this crude time trend was limited to mothers with higher educational achievement. Similar time trend effects were observed among less educated mothers only after adjustment for early cessation risk factors. Mutually adjusted hazard ratios for individual risk factors were similar in both studies: low education, high BMI, smoking within 6 weeks of delivery, and cesarean delivery were associated with early breastfeeding cessation beginning at 6 weeks. In addition, actively abstaining from drinking alcohol was associated with lower rates of early cessation.

CONCLUSIONS

Our results suggest widening socioeconomic disparity in breastfeeding and potentially subsequent child health, which may require new targeted interventions.
The Breastfeeding-Friendly Pediatric Office Practice
Authors: Meek Joan Younger , Hatcher Amy J.
Published: November 2021

The landscape of breastfeeding has changed over the past several decades as more women initiate breastfeeding in the postpartum period and more hospitals are designated as Baby-Friendly Hospitals by following the evidence-based Ten Steps to Successful Breastfeeding. The number of births in such facilities has increased more than sixfold over the past decade. With more women breastfeeding and stays in the maternity facilities lasting only a few days, the vast majority of continued breastfeeding support occurs in the community. Pediatric care providers evaluate breastfeeding infants and their mothers in the office setting frequently during the first year of life. The office setting should be conducive to providing ongoing breastfeeding support. Likewise, the office practice should avoid creating barriers for breastfeeding mothers and families or unduly promoting infant formula. This clinical report aims to review practices shown to support breastfeeding that can be implemented in the outpatient setting, with the ultimate goal of increasing the duration of exclusive breastfeeding and the continuation of any breastfeeding.
Defining Cyberbullying
Authors: Englander Elizabeth , Donnerstein Edward , Kowalski Robin , Lin Carolyn A. , Parti Katalin
Published: November 2021

Is cyberbullying essentially the same as bullying, or is it a qualitatively different activity? The lack of a consensual, nuanced definition has limited the field’s ability to examine these issues. Evidence suggests that being a perpetrator of one is related to being a perpetrator of the other; furthermore, strong relationships can also be noted between being a victim of either type of attack. It also seems that both types of social cruelty have a psychological impact, although the effects of being cyberbullied may be worse than those of being bullied in a traditional sense (evidence here is by no means definitive). A complicating factor is that the 3 characteristics that define bullying (intent, repetition, and power imbalance) do not always translate well into digital behaviors. Qualities specific to digital environments often render cyberbullying and bullying different in circumstances, motivations, and outcomes. To make significant progress in addressing cyberbullying, certain key research questions need to be addressed. These are as follows: How can we define, distinguish between, and understand the nature of cyberbullying and other forms of digital conflict and cruelty, including online harassment and sexual harassment? Once we have a functional taxonomy of the different types of digital cruelty, what are the short- and long-term effects of exposure to or participation in these social behaviors? What are the idiosyncratic characteristics of digital communication that users can be taught? Finally, how can we apply this information to develop and evaluate effective prevention programs?

Barriers and Stigma Experienced by Gay Fathers and Their Children
Authors: Perrin Ellen C. , Hurley Sean M. , Mattern Kathryn , Flavin Lila , Pinderhughes Ellen E.
Published: November 2021

BACKGROUND

Gay men have become fathers in the context of a heterosexual relationship, by adoption, by donating sperm to 1 or 2 lesbian women and subsequently sharing parenting responsibilities, and/or by engaging the services of a surrogate pregnancy carrier. Despite legal, medical, and social advances, gay fathers and their children continue to experience stigma and avoid situations because of fear of stigma. Increasing evidence reveals that stigma is associated with reduced well-being of children and adults, including psychiatric symptoms and suicidality.

METHODS

Men throughout the United States who identified as gay and fathers completed an online survey. Dissemination of the survey was enhanced via a “snowball” method, yielding 732 complete responses from 47 states. The survey asked how the respondent had become a father, whether he had encountered barriers, and whether he and his child(ren) had experienced stigma in various social contexts.

RESULTS

Gay men are increasingly becoming fathers via adoption and with assistance of an unrelated pregnancy carrier. Their pathways to fatherhood vary with socioeconomic class and the extent of legal protections in their state. Respondents reported barriers to becoming a father and stigma associated with fatherhood in multiple social contexts, most often in religious institutions. Fewer barriers and less stigma were experienced by fathers living in states with more legal protections.

CONCLUSIONS

Despite growing acceptance of parenting by same-gender adults, barriers and stigma persist. States’ legal and social protections for lesbian and gay individuals and families appear to be effective in reducing experiences of stigma for gay fathers.
Disparities for LGBTQ and Gender Nonconforming Adolescents
Authors: Baams Laura
Published: November 2021

OBJECTIVES

To identify patterns of childhood adversity in a sample of adolescents and assess disparities in these experiences for lesbian, gay, bisexual, transgender, and questioning adolescents and by level of gender nonconformity.

METHOD

By using the cross-sectional, statewide, anonymous 2016 Minnesota Student Survey, 81 885 students were included in the current study (50.59% male; mean age = 15.51). Participants were enrolled in grades 9 and 11 in a total of 348 schools.

RESULTS

Four patterns of childhood adversity were identified with sex-stratified latent class analyses (entropy = 0.833 males; 0.833 females), ranging from relatively low levels of abuse (85.3% males; 80.1% females) to polyvictimization (0.84% males; 1.98% females). A regression analysis showed that compared with heterosexual adolescents, gay, lesbian, bisexual, and questioning adolescents were more likely to be classified into profiles characterized by polyvictimization (odds ratio [OR] 1.81–7.53) and psychological and/ or physical abuse (OR 1.29–3.12), than no or low adversity. Similarly, compared with nontransgender adolescents, transgender adolescents were more likely to be classified into profiles characterized by patterns of polyvictimization (OR 1.49–2.91) and psychological and/or physical abuse (OR 1.23–1.96). A higher level of gender nonconformity predicted a higher likelihood of being classified into each adversity profile compared with the no or low adversity profile (OR 1.14–1.45).

CONCLUSIONS

Sexual minority adolescents and adolescents with high levels of gender nonconformity are vulnerable to experience adversity. The disparities for lesbian, gay, bisexual, transgender, and questioning adolescents and adolescents with high gender nonconformity highlight the variation in patterns of childhood adversity that these youth are at risk of experiencing. The findings reveal the need for further research on the benefits and harm of screening for childhood adversity by physicians and pediatricians.
LGBTQ Youth in Unstable Housing and Foster Care
Authors: Baams Laura , Wilson Bianca D.M. , Russell Stephen T.
Published: November 2021

BACKGROUND AND OBJECTIVES

Lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth are suggested to be overrepresented in unstable housing and foster care. In the current study, we assess whether LGBTQ youth are overrepresented in unstable housing and foster care and examine disparities in school functioning, substance use, and mental health for LGBTQ youth versus heterosexual youth in unstable housing and foster care.

METHODS

A total of 895 218 students (10–18 years old) completed the cross-sectional California Healthy Kids Survey from 2013 to 2015. Surveys were administered in 2641 middle and high schools throughout California. Primary outcome measures included school functioning (eg, school climate, absenteeism), substance use, and mental health.

RESULTS

More youth living foster care (30.4%) and unstable housing (25.3%) self-identified as LGBTQ than youth in a nationally representative sample (11.2%). Compared with heterosexual youth and youth in stable housing, LGBTQ youth in unstable housing reported poorer school functioning (Bs = 20.10 to 0.40), higher substance use (Bs = 0.26–0.28), and poorer mental health (odds ratios = 0.73–0.80). LGBTQ youth in foster care reported more fights in school (B = 0.16), victimization (B = 0.10), and mental health problems (odds ratios = 0.82–0.73) compared with LGBTQ youth in stable housing and heterosexual youth in foster care.

CONCLUSIONS

Disparities for LGBTQ youth are exacerbated when they live in foster care or unstable housing. This points to a need for protections for LGBTQ youth in care and care that is affirming of their sexual orientation and gender identity.
PrEP and Adolescents: The Role of Providers in Ending the AIDS Epidemic
Authors: Hosek Sybil , Henry-Reid Lisa
Published: November 2021

Surveillance data on high school adolescent sexual activity, including teenaged pregnancy rates and incidence of sexually transmitted infections (STIs), require pediatricians and other youth providers to be competent and confident in addressing sexual and reproductive health care needs in adolescent and/or young adult populations. The American Academy of Pediatrics has published guidelines, recommendations, clinical reports, and resources on the promotion of healthy sexual development in clinical settings, encouraging sexual health assessments that are inclusive of HIV and STI testing as an integral component of comprehensive health visits. The need for a more determined effort to address sexual health as it relates to HIV specifically is evidenced by a decrease in the number of in-school youth reporting ever being tested, 15- to 24-year-olds representing 21% of new infections, and estimates that .40% of youth with HIV are undiagnosed. Ending the HIV epidemic requires adherence to published HIV testing recommendations, sexual health assessments, screening for STIs, and appropriate primary and secondary prevention education. Preexposure prophylaxis, an efficacious biomedical prevention intervention for reducing HIV acquisition, was approved in July 2012 and in May 2018 was authorized for use in minors. This state-of-the-art review article provides background information on preexposure prophylaxis, current guidelines and recommendations for use, and strategies to introduce and implement this valuable HIV prevention method in clinical practice with adolescents and young adults.

Serum clinical biochemical markers of Hy-Line W-36 laying hens under the influence of increased stocking densities in cages of multilevel batteries
Authors: Osadcha Y. V. , Sakhatsky M. I. , Kulibaba R. O.
Published: November 2021

Today, the organism of hens is constantly exposed to numerous technological stressors in the conditions of industrial poultry farming, the least studied of which are long-term, which can cause the development of chronic stress. One of such stressors is the increased stocking density of hens, which is also a way of saving resources in egg poultry and is often used by producers to obtain more eggs per 1 m2 of poultry area. The aim of this study was to examine the effect of overcrowding, as a factor of chronic stress development, on the body of hens of a modern high-performance cross, which is necessary to select the best ways to keep them. Four groups of hens were formed for this purpose, which were kept at different stocking densities, according to European standards, Ukrainian standards and with increasing overcrowding. In this way, the gradually increasing intensity of the technological stressor was modeled. Long-term keeping of laying hens at high stocking density did not affect the content in the serum of total protein, albumin, urea and cholesterol, which were within the physiological norm. It was found that the increase in the stocking density of hens to Ukrainian standards, compared to the European, was accompanied by an increase in the activity of lactate dehydrogenase in the serum of their blood. With an increase in stocking density above European and Ukrainian standards, namely to 25.3 birds/m2, there was an increase in the activity of three enzymes – lactate dehydrogenase, aspartate aminotransferase and gamma-glutamyltransferase. It is proved that further overcompaction of hens to 26.7 birds/m2 is accompanied by an increase in serum glucose, creatinine, as well as a decrease in the ratio of calcium and phosphorus, which was confirmed by an increase in alkaline phosphatase activity. Also, increased activity of aspartate aminotransferase, lactate dehydrogenase and gamma-glutamyltransferase was observed. Thus, the main effects of chronic stress caused by prolonged keeping of hens at high stocking densities are reflected in the biochemical parameters of their serum, namely in the increase of glucose, creatinine, enzyme activity, as well as the violation of the ratio of calcium and phosphorus.

The regulation of metabolic processes and maintenance of a stable internal environment of the body is the role of the autonomic nervous system (ANS). It influences all systems and organs, thus along with the neuro-humoral system providing control over the metabolism of proteins, fats and carbohydrates. Amino acids, as structural units of any protein molecule, are essential for the metabolism of proteins, enzymes and hormones. Certain amino acids are involved in neutralizing free radicals and are a donor of metal groups, can act as an energy source in case of a deficiency of carbohydrates and fats, and be structural units of connective tissue. Exchange of these compounds and their regulation by ANS have not been studied sufficiently, therefore, it is necessary to carry out research in this direction. The studies were aimed at finding the presence of the regulatory effect of ANS on the content of individual amino acids in the blood serum of 60-day-old Cobb-500 chickens. Determination of the ANS tone in Cobb-500 chickens at the age of 30–35 days was determined by the method of variation pulsometry. Electrocardiographic examination was performed in a quiet room without the use of sedatives. At the age of 60 days, blood was obtained from the saphenous vein of the chickens’ shoulder. Blood was sampled from 10 am to 1 pm, after a short fasting (2:00). It was found that sympathicotonic chickens had a higher content of individual amino acids compared to normotonics and vagotonics. In vagotonic chickens, the content of glycine and serine in the blood serum significantly exceeded the rate of chickens with a balanced tone of ANS. Correlative relationships between amino acid content were highly significant in poultry with balanced ANS tone. Vagotonic chickens had the highest correlations between ANS tone, heart rate and amino acid content (trend). Correlative relationships were present between ANS and body weight of chickens of different groups, serum protein. The correlation between total serum protein and body weight of chickens was different depending on the tone of the ANS. Fisher’s test revealed a significant effect of balanced ANS tone on the content of valine, serine and glycine and the weight of chickens. The effect of ANS tone on weight in vagotonic birds was high.

Impaired metabolism of mineral substances in the conditions of industrial rabbit breeding may cause decrease in increment of live mass, reduction of immunity, mass morbidity and death of animals. In our experiment, we studied the efficiency of using a mineral mixture to prevent the disorders in the metabolism of rabbits according to changes in morphologic, biochemical parameters and antioxidant status of blood, chemical composition of blood plasma and increments in body weight compared to the control group of animals. For the studies, we formed four groups of white New Zealand rabbits, each comprising six individuals aged 70 days with mean body weight equaling 1.99 kg. In group I, the rabbits received an aqueous form of a mixture of glauconite, succinic acid, humic and fulvic acids and lactates of zinc, manganese, cuprum, cobalt and iron with water, rabbits of group II were given a dry form of a mixture of glauconite, succinic acid, humic and fulvic acids and lactates of zinc, manganese, cuprum, cobalt and iron with fodder, and the rabbits of group III were intramuscularly injected with butanol fraction of humic acids. The experiment lasted for 21 days. The results of the experiment indicate that the most effective prophylaxis of malfunctions of mineral metabolism in white New Zealand rabbits aged 70–95 was dry mixture of glauconite, succinic acid, humic and fulvic acids and lactates of zinc, manganese, cuprum, cobalt and iron with fodder (group II), which was given once a day for 21-day period. We determined a positive effect of biologically active supplement on the parameters of hematopoiesis(1.25 times significantly higher level of hemoglobin and 1.14 times higher number of erythrocytes), metabolism of proteins (1.54 times significantly higher content of albumins), mineral substances (significantly higher content of inorganic phosphorus – by 1.17 times, calcium by 2.18 times, manganese by 1.39 times, zinc by 1.50 times, iron by 1.39 times and cuprum by 1.49 times), functional condition of the liver (2.04 times lower activity of gamma-glutamyltransferase), the state of the antioxidant system (lowest catalase activity) and energy of rabbits’ growth (1.20-fold increment in body weight). The results of our study indicate that using a dry form of the mixture of glauconite, succinic acid, humic and fulvic acids and lactates of zinc, manganese, cuprum, cobalt and iron with fodder is an efficient method of preventing malfunctioning of mineral metabolism in rabbits.
Procesos de ejercicio y vulneración de derechos de niñas, niños y adolescentes con medida excepcional en Córdoba, Argentina, entre enero de 2016 y marzo de 2020
Authors: Chiora Daiana Laura
Published: November 2021

El presente artículo reflexiona, desde un enfoque de derechos, sobre las intervenciones realizadas por los agentes del Sistema de Protección de Derechos en los procesos que transitan niñas, niños y adolescentes (NNyA) que cuentan con una medida excepcional de protección. La pregunta de investigación fue: ¿cuál es la influencia de las medidas excepcionales en el ejercicio de derechos de las/os NNyA que fueron sujetos de intervención de la Unidad de Trabajo Social del Hospital de Niños de la Santísima Trinidad de Córdoba, Argentina, entre enero de 2016 a marzo de 2020? El objetivo fue analizar la influencia de estas medidas sobre el ejercicio y vulneración de derechos de estas/os NNyA en el período indicado. Se utilizó un enfoque cualitativo y un diseño documental, analizando los registros de las profesionales en Trabajo Social de dicho hospital. Se pudo concluir, entre otras cosas, que los procesos de ciudadanía en términos concretos de las/os NNyA con medida excepcional no siempre son efectivos, puesto que se encuentran atravesados por prácticas (de protección y restitución y de vulneración específica de derechos) aún vigentes del enfoque del Control Social de la Infancia llevadas a cabo por las/os profesionales del Sistema de Protección Integral de los Derechos de las/os NNyA.

Published: November 2021

Poverty is one of the main problems of the government that is prioritized in developing the development strategy of every country including Indonesia. The poverty rate in Indonesia is still relatively high, so the government focuses on decreasing the existing poverty level by improving the welfare of the population. Therefore, it is very important for the government to know the severity of poverty in Indonesia so that it can take a policy to reduce the existing poverty level. The purpose of the research was to group the severity of provincial poverty in Indonesia with a Discriminant Analysis. The stages of discriminant analysis include testing of normal multivariate distribution, testing of homogeneity of covariance variants, discriminant analysis by stepwise method, then continued calculation of classification accuracy value. The results of this research show that the large classification rate obtained is only 67.7% which means that not all provinces are able to be classified appropriately based on the variable open unemployment rate (TPT).

The Third-level Digital Divide among Elderly Hungarians in Romania
Authors: Tőkés Gyöngyvér Erika
Published: November 2021

The aim of the present study is to examine the characteristics of the third-level digital divide among elderly Hungarians (over 65 years of age) in Romania. The third level of digital divide indicates the emergence of digital habits in the Bourdieusian sense, which provide real benefits in different areas of everyday life. Hungarian elderly people in Romania are clearly lagging in terms of the third-level digital divide. The explanation for this is partly to be found in the limits imposed by the characteristics of their age and partly in their socio-economic situation. Elderly Hungarian people in Romania tenaciously adhere to their usual ways of life and previously established daily habits, and their repertoire does not integrate the use of digital technology. The results obtained in this study of elderly Hungarians in Romania are in line with the research results of digital inequalities, according to which there is a relationship between the degree of digital competence, the structure and usefulness of digital activities, and inequalities according to the traditional dimensions of social stratification (economic, cultural, individual).

On the way towards this formula, we prove explicit estimates on the Beurling zeta function , belonging to , to the number of zeroes of in various regions, in particular within the critical strip where the analytic continuation exists, and to the magnitude of the logarithmic derivative of , under the sole additional assumption that Knopfmacher’s Axiom A is satisfied. We also construct a technically useful broken line contour to which the technic of integral transformation can be well applied. The whole work serves as a first step towards a further study of the distribution of zeros of the Beurling zeta function, providing appropriate zero density and zero clustering estimates, to be presented in the continuation of this paper.

The terrestrial predatory leech of the genus Orobdella Oka, 1895 is recorded for the first time from Moneron Island, which is located southwest of Sakhalin, Russia. Morphological characteristics of the Moneron Orobdella clarify its taxonomic identification as O. kawakatsuorum Richardson, 1975, which is indigenous to Hokkaido Island in the Japanese Archipelago. The occurrence data extends the northernmost range of the genus Orobdella and shows that the leech fauna is shared between Moneron Island and Hokkaido.
Реалізація проекту розробки програмного забезпечення автоматизованого керування процесом формування розкладу навчальних занять засобами пакета Gantt Project

Published: November 2021

Основою якісної організації освітнього процесу будь-якого навчального закладу, особливо закладу вищої освіти є розклад навчальних занять. Якість підготовки спеціалістів в значній мірі залежить від методично правильного сформованого розкладу навчальних занять. Розклад навчальних занять та екзаменів є одним з найбільш відповідальних, трудомістких та стомлюючих завдань планування освітнього процесу [1].
Дослідники доклали значних зусиль для розробки універсальної автоматизованої системи керування процесом формування розкладу навчальних занять. Однак на сьогоднішній день немає ідеального рішення цієї проблеми, тому що ми повинні враховувати численні параметри та обмеження. Жодна з раніше розроблених систем не є універсальною і не може задовольнити потреби всіх вищих навчальних закладів. Більшість систем використовують велику кількість вхідної інформації, що зберігається в базах даних. За допомогою складних алгоритмів на основі аналізу вхідної інформації складається розклад. Однак підсумковий графік не завжди ідеальний і може потребувати багато ресурсів та часу. Розклад повинен задовольняти інтереси всіх учасників процесу [2]. Для розробки такої системи потрібно якісно розподілити роботи між виконавцями. Створення, будь-якого проекту завжди починається з його плануванням. Для виконання цих завдань уже давно багато компаній використовують системи управління проектами, які дозволяють ставити певні завдання, визначати людей, слідувати за процесом виконання завдань та виділенням необхідних ресурсів.
Завдання управління проектом програмного забезпечення може бути надзвичайно складним, виходячи з багатьох особистих, командних та організаційних ресурсів. Якість програмного продукту залежить від процесу завершення проекту. Час затримок у проекті з розробки програмного забезпечення та низька продуктивність, як правило, впливають на кінцевий результат. Останнім часом еволюція інструментів управління проектами як для програмних, так і для непрограмних додатків прискорюється швидкими темпами, а кількість доступних продуктів значно зросла. Щодня розробляється багато інструментів та програмного забезпечення для управління проектами, які допомагають менеджерам автоматизувати адміністрування окремих проектів або груп проектів протягом їх життєвого циклу [3].

У статті розглядається процес виявлення та дослідження чинників, що впливають на успішність веб ресурсів підрозділів закладів вищої освіти (ЗВО). В процесі дослідження проведено аналіз робіт присвячених цьому питанню, проведено аналіз існуючих популярних серед користувачів веб ресурсів, виявлено критерії оцінки таких систем. В роботах інших авторів, які проводили аналогічні дослідження, аналізуються чинники, які впливають на підвищення якісного рівня веб-сайтів, доведено, як важливо підвищувати комунікативну функціональність сайту, його відвідуваність та відгук аудиторії. Для досягнення мети, поставленої авторами даної роботи, було проведено опитування серед потенційних споживачів веб ресурсів. Розподіл респондентів за віком та фаховими категоріями дозволило виявити, що в основному споживачами сайтів кафедр ЗВО є здобувачі освіти. Аналіз результатів проведеного опитування користувачів сайтів ЗВО допоміг виявити чинники, що впливають на їх успішність та побудувати модель успішності веб ресурсів підрозділів ЗВО, яка стала важливим інформативним фактором для прийняття рішення про дизайн, елементи та зміст нової веб системи. Розроблена модель впроваджена у процесі розробки нового веб-ресурсу кафедри Інформаційних технологій та кібербезпеки ОНАХТ, що забезпечило підвищення ефективності подачі інформації, привабливість та затребуваність зазначеного ресурсу. Отримані в дослідженні результати можуть використовуватися при побудові різноманітних інформаційних ресурсів підрозділів закладів вищої освіти для підвищення їх привабливості, інформативності та відвідуваності. планується подальша робота з  вдосконалення розробленої моделі і веб системи, що її використовує.

Відмічено, що для підвищення ефективності процесів прийняття управлінських рішень, доцільним є забезпечення можливості розв’язання задач, які виникають при цьому, методами інтелектуального аналізу даних, статистичними методами аналізу даних, методами теорії прийняття рішень тощо.
Розроблено структурно-функціональну схему системи підтримки прийняття рішень в умовах ризику і невизначеності. Показано, що логічно функціональний блок системи підтримки прийняття рішень доцільно розділити на дві частини: блок аналізу вхідних даних та висновків експертів і блок вибору оптимальних альтернатив. Важливою складовою системи підтримки прийняття рішень є база даних та знань у якій накопичуються як вхідні дані, так і результати застосування включених у систему моделей і методів.
Дотримання запропонованої схеми при проектуванні програмних продуктів для задач прийняття рішень у різних предметних областях, дозволить зробити ці програмні продукти цілісними та універсальними. Використання таких програмних продуктів забезпечить незалежність особи, що приймає рішення на всіх етапах прийняття управлінських рішень в умовах ризику і невизначеності.

Background. Children with congenital epidermolysis bullosa (CEB) can have vitamin D deficiency due to its malabsorption in intestine and reduced synthesis in skin as these patients have restrictions on staying in the sun. However, the prevalence of vitamin D insufficiency/deficiency among patients with CEB remains not fully studied due to the small samples' sizes in previously studies.Objective. Our aim was to study vitamin D provision in children with CEB.Methods. The study included children aged from 3 to 18 years old with simplex and dystrophic types of CEB hospitalized in our department. The serum level of 25(OH)D was determined via chemiluminescence immunoassay. Vitamin D deficiency was established at 25(OH)D concentration of 20-30 ng/ml, deficiency — < 10-20 ng/ml, deep deficiency — < 10 ng/ml.Results. The study included 129 children with CEB (62 (48%) males, median age 6 (3; 10) years). 101 patients had dystrophic type of disease, 28 — simplex. The median 25(OH)D serum concentration in children with CEB was 21.7 (13.0; 36.6) ng/ml. Vitamin D insufficiency was revealed in 36 (28%) patients, deficiency — in 38 (29%), deep deficiency — in 16 (12%). Independent predictors of 25(OH)D concentration were the type of CEB (concentration was higher in children with simplex type) and age (negative association), but not the patients' gender and the examination season, according to multivariate regression analysis.Conclusion. The study has shown low level of vitamin D provision in children with CEB, whilst 25(OH)D concentration depended on the type of disease and the age of patients.
Narrativas de uma professora de bebês: a busca por réplicas das infâncias em tempos pandêmicos
Authors: Simas Vanessa França , Prado Guilherme do Val Toledo
Published: November 2021

RESUMO O presente artigo objetiva revelar como as réplicas dos outros compõem e ampliam as narrativas de uma professora de bebês e, ainda, como essas réplicas apareceram nessas narrativas no contexto de atendimento não presencial e assíncrono devido à pandemia de covid-19. A metodologia narrativa de pesquisa em educação, em diálogo com os aportes da filosofia bakhtiniana, foi a utilizada para interpretar as réplicas materializadas nas narrativas e a maneira como a professora reorganizava seu trabalho a partir delas. Revelou-se que, enquanto as narrativas eram referentes ao trabalho presencial, as réplicas dos bebês apareciam a partir do acabamento provisório que a professora produzia do vivido com eles; já, nas narrativas que tratavam do trabalho não presencial, as réplicas eram os acabamentos produzidos pelas famílias, a partir do vivido na relação com os bebês. Em ambas as situações, a professora buscou reorganizar o trabalho na relação com as réplicas de seus outros.

Abstract Tulip (Tulipa sp.) is of the highest economic importance and cultivated area among all bulbous ornamental species. The spray of alcohol is regarded as a proper strategy to improve plant yields in sustainable agriculture systems. This study aimed to investigate the effect of different rates of ethanol and methanol on the traits of the tulip in a factorial experiment based on a Randomized Complete Block Design with two factors including ethanol at four levels (0, 10, 20, and 30 vol%) and methanol at four levels (0, 10, 20, and 30 vol%). The estimated traits included anthocyanin, carotenoid, chlorophyll a and b, total chlorophyll, stem and leaf Brix index, leaf length and width, leaf area, total and bulb fresh and dry weight, leaf number, and flowering stalk length. Analysis of variance showed that the simple and interactive effects of different treatments were statistically significant on most estimated traits. The highest anthocyanin content (3.92 mg 100 g-1 DM), leaf length (25.83 cm), leaf area (258.6 cm2), and bulb fresh weight (25.81 g) were obtained from the plants treated with 30% ethanol, and the highest anthocyanin content (3.45 mg 100 g-1 DM) and leaf Brix index (10.15%) were related to 30% methanol. It can be concluded from the results that methanol and ethanol can be used as plant growth regulators.

Abstract Occlusion of the stem vasculature by microorganisms that proliferate in the vase water, or the plant vessels, leads to water stress symptoms that reduce postharvest quality of cut flowers. This study aimed to determine the effects of pulsing and wet-cold storage on the microbial profiles in cut Gladiolus grandiflorus L. cv. Fado. Pulsing treatments of 600-ppm 8-hydroxyquinoline sulfate plus 5% sucrose solution versus distilled water were administered before wet cold storage periods of 0-5 days in cut Gladiolus, previously grown from corms under open field. A two-by-six factorial experiment embedded in a completely randomized design with four replicates was accomplished. Proc GLM in two-way Anova was adopted, and the means were separated using Tukey’s test at a 5% level of significance. The pulsing treatment of 600 ppm 8-HQS plus 5% sucrose, the wet cold storage duration and their interactive effects significantly (P˂0.0209; ˂0.0001 and ˂0.0001 respectively) affected the means of the colony-forming units in the vase water of cut Gladiolus at senescence. The prolonged vase life of cut gladioli spikes was associated with decreased microbial proliferation as influenced by pulsing and wet storage duration of up to 4 days. Data generated from this study will improve existing technologies related to the quality and market value of this Gladiolus cultivar.
Experimental evaluation of salinity geosynthetics capillary barriers
Authors: Bouazza A.
Published: November 2021

This paper explores the transient upward flow of saline water in one-dimensional soil and soil–geosynthetics columns to evaluate preventive measures to mitigate salinity rise. Unsaturated soil concepts are utilised to elucidate the salinity movement through geotextile and geocomposite drain interfaces. The presence of a geotextile layer slowed down the capillary rise of the saline water. However, it did not prevent the breakthrough of the saline water due to the hydrophilicity of the geotextile and the suction at the geotextile base being close to the geotextile's water entry suction value. In contrast, using a geocomposite drain mitigated the upward saline wetting front. It acted as a salinity capillary barrier due to the initial hydrophobicity of its geotextile component and the air gap present in the geonet core.
A new method for structural safety and reliability analysis of offshore wind turbines
Authors: Wang Yingguang
Published: November 2021

With the motivation to overcome the shortcomings of the Rosenblatt inverse-first-order reliability environmental contour method (IFORM), in this study, the use of bivariate kernel density estimation with smoothed cross-validation bandwidth selection method is proposed for generating more accurate environmental contour lines. The environmental contour lines at a chosen offshore site obtained by using the proposed new method were compared with those obtained by using the Rosenblatt IFORM, and the accuracy and effectiveness of the proposed new method have been fully and clearly substantiated. Next, the 50 year extreme structural dynamic responses of a monopile-supported 5 MW offshore wind turbine installed at this chosen offshore site based on the proposed new method and the Rosenblatt IFORM were calculated. Analysing the calculated results, it can be found that the 50 year extreme fore−aft shear force value based on the 50 year extreme sea state obtained using the proposed new method is 78.9% larger than the corresponding value obtained based on the Rosenblatt IFORM. The calculation results in this paper were further systematically analysed and compared, and the necessity and importance of using more realistic environmental contour lines (such as those generated using the proposed new method) have been finally highlighted.

Al-5Cu, 2xxx serisi Al-esaslı alaşım grubundan olup hafif ağırlığın gerektirdiği otomotiv ve havacılık endüstrisinde geniş bir kullanım alanına sahiptir. Al-5Cu alaşımlarının en belirgin özellikleri, düşük yoğunluk, yüksek erime sıcaklığı, iyi termal iletkenlik, yüksek dayanım ve tokluktur. Bu araştırmada, Al-5Cu alaşımının mekanik özelliklerinin geliştirilmesi amaçlanmıştır. Bu sebeple, ağ.% 0.5 ve 1.0 oranında Skandiyum (Sc) katkılı Al-5Cu alaşımı indüksiyonla ergitme yöntemi ile üretilmiştir. X-ışınımı kırınımı (XRD) analizlerinden, Al-5Cu alaşımında Al ve Al2Cu fazları gözlenirken, Sc katkılı alaşımlarda bu fazların yanında Cu2Sc fazı tespit edilmiştir. Taramalı elektron mikroskobu (SEM) analizlerinden, Sc katkısının, külçe alaşımların mikro yapısını büyük oranda incelttiği görülmüş ve ayrıca, Sc katkılı alaşımlarda yarı-kararlı iğnemsi θ'-Al2Cu fazlarına rastlanılmıştır. Ayrıca alaşımlarda gözlenen mekanik özelliklerindeki iyileşme, tane boyutu sertleşmesi ve çökelti sertleşmesi mekanizmaları ile açıklanmıştır. Nano çentme testi sonuçlarından, Sc elementinin Al-5Cu alaşımını mekanik özellikleri bakımından büyük oranda geliştirdiği anlaşılmıştır.
