Meslek, kişinin geçimini sağlayabilmesi için icra ettiği iştir. Kişi, hangi mesleğe sahip olmak istiyorsa o alanla ilgili meslekle alakalı eğitim alınmalıdır. Bireylerin meslek seçimlerinin hayatları boyunca aldıkları en önemli kararlardan
biridir. İnsanların gelecek yaşantılarındaki mutluluklarının ve hayatlarını etkileyecek birçok faktörün seçilen meslekle ilişkili olması gerçeği vazgeçilmezdir. Ülkemizde bireyin meslek sahibi olabilmesi ortaöğretim düzeyinde meslek
okulları ve yüksek öğretim seviyesinde üniversiteler vasıtasıyla olmaktadır. Sınıf öğretmeni olabilmek için gerekli şartlar yıllar içinde değişiklik göstermektedir. Geleceğe yön veren öğretmenlerimizin yıllarca öğrenci ve sonrasında
öğretmen olarak rol aldıkları eğitim sistemine ilişkin metaforları hiç şüphesiz büyük önem arz etmektedir. Sınıf öğretmenleri Türk eğitim sisteminde anasınıfından başlayarak üniversiteye kadar öğrenci rolüyle okumuş ve nihayetinde
öğretmenlik seviyesine ulaşmış kişilerdir. Sistemdeki her sınava girmiş, değişikliklerden birinci derecede etkilenmiş öğretmenler kendi öğrencilerinin en iyi şekilde öğrenim görüp başarılı olması için fedakarca çalışan toplumun
hizmet elemanlarıdır. Toplumdaki tüm meslek kollarında görev alan vatandaşları yetiştiren sınıf öğretmenleridir. Öğrencilerine örnek olup onların hayatında önemli dokunuşlarda bulunurlar. Sınıf öğretmenlerinin yıllarca öğrenci
rolüyle bulundukları sistemde rol değiştirip gelecek nesilleri yetiştirirken var olan düzene ilişkin görüş ve metaforlarını belirlemek mühim bir olgudur. Çalışmada kamu ve özel sektörde çalışan sınıf öğretmenlerinin Türk eğitim
sistemine ilişkin metaforlarını incelemek amaçlanmıştır. Bu araştırmada tarama modeli kullanılmıştır. Çalışmada bir büyükşehirin üç farklı ilçesinde yer alan benzer sosyo ekonomik düzeye sahip altı farklı ilkokulda görev yapan

Dos sentidos que são responsáveis pela percepção humana do ambiente, o ½v¨v?vÀ e o olfato são os que se comunicam quimicamente com o meio e atuando em conjunto, possibilitam o paladar. O paladar é caracterizado pela capacidade de reconhecer o aroma, o gosto, além da sensibilidade tátil quanto aÃ substâncias químicas que entram pela via oral, fazendo contato com receptores específicos presentes na língua (sensação do sabor) e com receptores olfatórios (sensação do aroma) (Smith, 2001). O paladar é chamado de sentido químico, devido a seus receptores serem excitados por estímulos químicos. Os receptores gustativos são excitados por substâncias químicas presentes nos alimentos que ingerimos ao passo que os olfativos são excitados por substâncias químicas do ar (Araújo, 2001).

Exploring dynamic pedagogical content knowledge across fundamental concepts of electrostatics
Authors: Mazibe Ernest Nkosingiphile , Gaigher Estelle , Coetzee Corene
Published: March 2023

This paper reports a case study that explored teachers’ dynamic pedagogical content knowledge (PCK) across three big ideas of electrostatics namely the electrostatic force, electric field, and electric field strength. Two pre-service and two in-service teachers participated in the study. The refined consensus model of PCK was adopted as the theoretical framework for the study. We studied PCK as enacted during classroom teaching using observations and interviews. Data was analyzed alongside a four-point scale grand PCK rubric used to score the competence of the teachers for every big idea. The results showed that PCK of the teachers varied across the big ideas, which is attributed to the nature of concepts, as well as teachers’ content knowledge in each. The findings imply that pre-service teacher education programs should involve focus on teaching specific concepts to support the development of holistic PCK for a topic.

Background: the COVID-19 pandemic and associated restrictions may be particularly harmful for adolescents; however, evidence about changes in adolescent mental health during the pandemic is inconsistent.

The aim was to examine changes in levels of Russian adolescent mental health and rates of substance use during the COVID-19 pandemic.

Participants and methods: two cohorts of 11–18-year-old adolescents were recruited from Siberian cities in 2015–18 (n = 1774, 47% male) and in 2020–21 (n = 1747, 43% male). Participants completed identical sets of questionnaires: the Strengths and Difficulties Questionnaire, Body Image and Eating Distress scale and items on tobacco, alcohol and drug use. We examined the effect of cohort, gender and age using linear models.

Results: in the 2020–21 cohort, depression, anxiety and psychosomatic symptoms, total mental health problems and levels of substance use were higher than in the 2015–18 cohort. Increases in emotional symptoms and total mental health problems were similar in both genders, whereas increases in rates of smoking and alcohol use were significant only among girls.

Conclusions: the present findings indicate that the COVID-19 pandemic experience was likely to be stressful for adolescents. Therefore, more research on risk and protective factors of Russian adolescent mental health is needed. The findings also suggest that preventative interventions should be based on gender-specific patterns of adolescent substance use.

Authors: Selezneva N. D. , Roshchina I. F. , Gavrilova S. I.
Published: March 2023

The aim of the study: evaluation of the impact of long-term effects of repeated courses of Actovegin therapy on indicators of minimal cognitive dysfunction (MCD) in relatives of patients with Alzheimer’s disease (AD).

Study participant: 76 people with signs of minimal cognitive dysfunction objectively confirmed by clinical and neuropsychological examination, who are relatives of the 1st degree of relatives of patients with AD.

Study design: a prospective comparative study of the effects of repeated courses (4 courses in total) of three-month oral therapy with Actovegin (at a daily dose of 600 mg divided into three doses of 200 mg) every 1.5 years in groups of relatives with ApoE4(+) and ApoE4(–) genotypes.

Methods: psychometric, neuropsychological, molecular genetic, statistical.

Results: in the study, the effectiveness of 4 repeated courses of Actovegin therapy in relatives with manifestations of MСD was established. According to the CGI-I subscale, no deterioration was found over a period of 4 years and 9 months. By the end of the study, in 86.9% of all cases, a pronounced and moderate improvement was achieved.

Conclusion: minimal cognitive dysfunction in first-degree relatives of AD patients, both in carriers of the ApoE4(–) genotype and especially in carriers of the ApoE4(+) genotype, is the basis for special attention to measures to prevent cognitive deficits.

Authors: Heryak S.M. , Petrenko N.V. , Dobrianska V.Yu.
Published: March 2023

Premature birth (PB) is a polyetiological problem that depends on many factors, accompanied by violations of the placenta functional competence, changes in its metabolic, hormone-producing and protective functions. The objective: to establish the importance of placental factors in the development of PB in pregnant women with comorbid pathology. Materials and methods. The levels of fetal and placental proteins (placental alfa microglobulin-1, α2-microglobulin of fertility, trophoblastic β1-glycoprotein) and hormones (estriol, placental lactogen, progesterone) were determined in 33 pregnant women with threat of PB at 26–34 weeks of gestation (main group), who had concomitant comorbid pathology in the stage of unstable remission. The control group included 26 healthy pregnant women who were representative for gestational age. Results. In pregnant women with comorbid pathology a decrease of the placenta protein-synthesizing function and the hormone-producing function of the trophoblast was found, which makes it difficult to launch the syntoxic adaptation programs of the mother’s organism, which are responsible for maintaining the pregnancy with the subsequent development of placental dysfunction, the result of which is PB.The markers of these disorders are a 3-fold decrease in the level of trophoblastic β1-glycoprotein (p<0.0001) and a 1.7-fold decrease in the concentration of α2-microglobulin of fertility (p<0.0001) with a simultaneous 4-fold increase of placental alfa microglobulin-1 concentration (p<0.0001) and a decrease in the levels of placental lactogen by 1.6 times (p<0.0001), estradiol by 40 % (p<0.0001) and progesterone by more than 2 times (p<0.0001) compared to healthy pregnant women.Conclusions. In patients with comorbid pathology there are disorders in the secretion of pregnancy proteins due to a decrease in the levels of trophoblastic β1-glycoprotein and α2-microglobulin of fertility and an increase in the level of placental alfa microglobulin-1 and disorders of the hormone-producing function of the trophoblast due to a decrease in the secretion of placental lactogen, progesterone, and estradiol. The disturbance of the secretion of the pregnancy zone proteins and hormones are the early markers for the initiation of premature birth caused by placental dysfunction in pregnant women with comorbid pathology.

Published: March 2023

The objective: to conduct a retrospective clinical and statistical analysis of the pregnancy course, childbirth and the condition of newborns in women with HCV infection.Materials and methods. A retrospective clinical and statistical analysis of the pregnancy course, childbirth and the condition of newborns was carried out according to the data of 351 birth histories of women with HCV infection based on the materials of the archive of the communal non-commercial enterprise “Kyiv Municipal Center of Reproductive and Perinatal Medicine” for the period from 2016 to 2021. The control group (CG) included 50 healthy pregnant women. Statistical processing of research results was carried out using standard programs “Microsoft Excel 5.0” and “Statistica 8.0”. Results. In women with HCV infection compared to the group of healthy pregnant women a significantly high frequency (p<0.001) of such pregnancy complications was found: threat of pregnancy interruption – 64 (18.2 %) patients versus 2 (4.0 %) persons, edema of pregnant women – 72 (20.5 %) and 4 (8.0 %), respectively; preeclampsia – 45 (12.8 %) versus 2 (4.0 %), gestational anemia – 131 (37.3 %) versus 6 (12.0 %), as well as placental insufficiency with fetal growth retardation syndrome (FGR) – 69 (19.6 %) versus 3 (6.0 %; p<0.05) and intrahepatic cholestasis of pregnant women – 42 (11.9 %) versus 1 (2.0 %; p<0.05). In 73 (20.8 %) pregnant women with HCV infection the childbirth was complicated by premature rupture of the membranes, of which almost half of the cases (42 (11.9 %) of the patients) finished with premature birth, while in CG only some women had such complications. Fetal distress during childbirth was reliably detected more often in pregnant women with HCV infection than in CG women (χ2=4.76; p=0.024). Caesarean section was performed in 86 (24.5 %) patients with HCV infection versus 2 (4.0 %) persons in CG (p<0.001).The newborns from mothers with HCV infection had lower indicators of physical development and decreased Apgar score assessment, increased frequency of conjugation jaundice.Conclusions. Pregnant women with HCV infection are characterized by a significant increase in the number of pregnancy complications, such as the threat of pregnancy interruption, the threat of premature birth, gestational anemia, placental dysfunction, fetal growth retardation syndrome, and preeclampsia; during childbirth – premature and antepartum rupture of amniotic membranes, premature birth, weakness of uterine activity in labor, increased blood loss. The condition of newborns from women with HCV infection is characterized by a significant increase in the frequency of asphyxia during childbirth, CNS hypoxic-ischemic damage, prematurity and conjugation jaundice.

Authors: Christiandi Novem , Haryanto Budi , Jamal Mardewi
Published: March 2023

Flooding, a lack of potable water, and environmental harm caused by regional expansion are all issues that continue to plague Samarinda City. This research tries to persuade the community to use rainwater harvesting (RWH) systems as a solution to these issues, and then closes with the people of Samarinda's overall response. It was discovered that 33% of respondents collect and use rainwater for various reasons utilizing a survey method and descriptive analysis approach. Only 16 percent of the 33 percent use it for basic needs (cooking and drinking water). The majority of responders (80%) think that using rain water (RWH) can lessen the Regional Water Company's service load. However, the number of people who are aware of the favorable effects of RWH on the environment is still quite small, around 25%. The biggest reasons for respondents not installing RWH in their homes and environs are the expense of installation (26%) and space availability (52%) issues. In order to boost public interest in rainwater collecting with RWH installations in the future, more extensive and precise socialization activities and movements are required.

In order to evaluate the problem of employees using social networking technology for business purposes, the technology acceptance model will be applied. The purpose of the study is to establish the levels of impact exerted by the elements that influence the intentions of individuals working in the university to utilize social media. Employees in the university’s connections between “organizational support,” “colleague support,” “self-efficacy,” “technology capacity,” “perceived usefulness,” “perceived ease of use,” and “behavior intention” are acknowledged as factors in this study. It was possible to get a total of 247 copies that were legitimate. For the purpose of inferential statistics, the partial least squares structural equation modeling method was applied. The data indicate that colleague support and technological capabilities do not have any impact on how easily something may be used or how valuable it is thought to be. On the other hand, organizational support and self-efficacy have a favorable influence on the perceived ease of use, but they have no effect on the perceived effectiveness of the tool. Additionally, while perceived usefulness does not have any influence on behavioral intention, perceived simplicity of use does have a favorable effect on behavioral intention.

Authors: Jones Peter
Published: March 2023

Plant-based alternatives to meat and dairy products are one of the fastest growing sectors within the food industry, and in the US some commentators have claimed that plant-based products are a key driver of sales growth for food retailers. This paper looks to explore if, why, and how, the leading food retailers in the UK were introducing plant-based alternatives to meat and dairy products to their retail offer. The paper reveals that the leading food retailers in the UK have highlighted plant-based alternatives to meat and dairy produce within their retail offer, and that a range of such products are available within their stores. Further, the retailers claimed to be introducing plant-based alternatives to meat and dairy products as part of their response to consumer demand and to health and environmental concerns. A number of illustrations demonstrate how plant-based alternatives to meat and dairy products are presented within stores Keywords: plant-based alternatives, sustainability, leading food retailers, UK
Non-alcoholic fatty liver disease: current diagnostic opportunities at different stages of the disease and scientific developments in treatment. Review
Authors: Fadieienko G. D. , Nikiforova Y. V.
Published: March 2023

Nonalcoholic fatty liver disease (NAFLD) is a widespread disease and a major challenge for health care systems worldwide. Disease severity and end‑stage disease vary considerably among patients, so there is a need to identify those at greatest risk of disease progression. NAFLD is often asymptomatic, but should be suspected in individuals with risk factors. Marked liver fibrosis is the strongest predictor of long‑term mortality in patients with NAFLD and is one of the risk factors for the development of hepatocellular carcinoma (HCC). Liver biopsies are the gold standard for diagnosing the stage of liver fibrosis. However, this is an invasive procedure that cannot be widely used in a daily clinical practice. Therefore, there is a constant search for non‑invasive and safe biomarkers.
The purpose of this publication is to analyze and summarize the current research results of non‑invasive tests for fibrosis, as well as scientific developments in the NAFLD treatment, which can be widely used in daily clinical practice. Non‑invasive methods of diagnosing liver fibrosis can be divided into biochemical serum tests (serological) and morphological. Serum markers of fibrosis are studied based on participation in the mechanisms of fibrogenesis and fibrolysis. The authors outlined the effectiveness of different scales including different markers of fibrosis, but for widespread use in clinical practice, it is recommended to use simple and accessible tests and scales. One of the modern and safe instrumental diagnostic methods is transient elastography, which has excellent effectiveness for diagnosing liver fibrosis, predicting the development of HCC and other clinical stages. Two‑dimensional shear wave elastography is a new technique that provides real‑time imaging of stiffness. Further studies are needed to establish specific markers of liver fibrosis based on further clinical and molecular studies.
Recommendations for patients’ lifestyle changing with individualized approach to the non‑drug treatment administration are stated to be important for curation of patients with NAFLD. If patients adhere to such recommendations, the overall benefit for NAFLD regression and health can be quite significant. However, due to the insufficient compliance of some patients with non‑drug treatment, a constant search for candidate molecules for NAFLD treatment is conducted. At the current stage, there are no approved recommendations for drug treatment, thus the research in this direction is ongoing. The article provides up‑to‑date information on the stages of studying the main existing molecules
Modification of the intestinal microbiota under the influence of combined treatment to prevent the progression of non-alcoholic fatty liver disease
Authors: Kushnir I. E. , Solomentseva T. A.
Published: March 2023

Nonalcoholic fatty liver disease (NAFLD) is a common disease with a steadily increasing incidence. Clinical and experimental studies of recent years testify to the key role of intestinal microbiota (IM) imbalance in the development and progression of NAFLD.

Objective — to determine the effects of combined therapy on the state of the intestinal microbiota and to prevent the progression of NAFLD.

Materials and methods. Investigation involved 108 patients NAFLD with metabolic disorders and 30 people of the control group, who were examined on the basis of the Department of Gastroenterology and Therapy, and out‑patient ward of the L. T. Malaya Therapy National Institute. Women prevailed in both investigated groups. The mean age of NAFLD patients was 54.6 ± 11.7 years. NAFLD patients were randomized into two comparable groups based on quantity, gender and age. Both groups received non‑drug therapy (correction of nutrition, increased physical activity). In addition, group I (60 patients) received ursodeoxycholic acid (UDCA) in a dose of 1000 mg, and probiotic preparation «Yogurt» capsules (2 billion active CFU cells) orally 1 capsule three times a day during meals. Comparison group II (48 patients) received only UDCA in a dose of 1000 mg. Treatment duration was 12 weeks. The patients were examined before and at the end of the treatment, with determination of the levels of main IM phyla, endotoxin, fetuin A. The dynamics of the degree of liver steatosis and fibrosis were also evaluated. Statistical processing was carried out using the package Statistica 13.1 using non‑parametric methods.

Results. Additional administration of the probiotic drug resulted in the significant reduction of the Firmicutes quantity with simultaneous slight increase in the Bacteroidetes levels, but the changes did not reach the indicators of the control group. At the same time, the diversity of IM increased. The improvement of the IM balance was accompanied by a significant decrease of endotoxin level in patients with NAFLD who received combined therapy with the involvement of probiotic yogurt capsules. Under the influence of the developed treatment, a tendency to decrease the degree of liver steatosis and fibrosis was observed. In comparison group II, the dynamics of restoration of the liver tissue structure was less pronounced.

Conclusions. The developed therapy positively contributed to improving the intestinal microbiota state, normalizing the functional state of the intestinal epithelial barrier, and reducing endotoxemia. The use of the developed complex therapy reduced the degree of fatty infiltration of hepatocytes and stopped the progression of liver fibrosis in the initial stages.
Intestinal permeability and its role in the pathogenesis and progress of non-alcoholic fatty liver disease. Review

Non‑alcoholic fatty liver disease (NAFLD) is a topical problem for the medicine worldwide, and its association with an «unhealthy» lifestyle and metabolic disorders is well established. The important role of dysbiosis of the intestinal microbiota in the NAFLD pathogenesis and the functioning of the intestine‑liver axis is emphasized. Data on the structure and functioning of the intestinal barrier in physiological conditions are presented. It has been proven that the presence of dysbiotic changes in the microbiota plays an important role in the disruption of the barrier function of the gastrointestinal tract, which in turn increases the level of physiological translocation of both bacteria and their toxins and their life products. Part of these harmful products comes to the liver through the portal vein (endotoxinemia). The antigens’ overload contributes to the development and progression of NAFLD (up to liver cirrhosis). The intestinal barrier is emphasized to be dynamic and sensitive to changes occurring in the intestine. The increased intestinal permeability and bacterial overgrowth syndrome (which is a source of increased endotoxemia) is observed in patients with NAFLD more frequently than in healthy subjects. Number of studies have revealed that the degree of intestinal permeability in NAFLD patients correlated with the steatosis severity. The factors that most significantly affect intestinal permeability in patients with NAFLD include microbial environment, bile acids, levels of fecal short‑chain fatty acids (mainly butyrate), the metabolism of the essential aromatic amino acid tryptophan, as well as the nature of nutrition, alcohol intake, medicinal preparations, stress, and level of physical activity, which act either directly or through the induction of intestinal microbiota dysbacteriosis. The increased intestinal permeability and its consequence — bacterial translocation, are noticed to be involved in the development of such complications as spontaneous bacterial peritonitis, hepatorenal syndrome, portal vein thrombosis, hepatic encephalopathy, hepatocellular carcinoma.

The goals of this research are to look at the connection between performance and human resource development, compensation, and motivation. Private schools were used for this study. The research sample was taken from 42 private school teacher respondents. Quantitative research is the kind of study being conducted. For this study's data analysis, several types of linear regression were applied. The findings of the study reveal that salary and motivation both have a substantial impact on the performance of teachers in private schools. This is indicated by the human resource development variable. Partly, motivation has a substantial effect on teacher performance in private schools with a significance level of less than 0.05 or 5%, whereas human resource development and compensation have no meaningful impact
