The paper reveals the results of electrochemical studies of activated nanoporous carbon material (NPC) as an electrode material for electrochemical capacitors (EC), the charge of which is accumulated in an electrical double layer (EDL). NPC material has been obtained from raw material of plant origin (hemp shives) by thermochemical activation using phosphoric acid. It has been established that there is an optimal ratio between the amount of acid and precursor based on plant biomass that is equal to 0.75:1. The specific surface area of ​​the obtained NPCwas ~ 2000 m2/g, and the maximum specific capacitance of EC models based on them was ~ 113 F/g. At the same time, the contribution of the EDL capacitance to the total capacitance is 60-80 %.

A colorectalis carcinoma (CRC) az egyik leggyakrabban előforduló daganatos
megbetegedés világszerte. A sporadikus vastagbélrák incidenciája ötvenéves kor
alatt alacsonyabb, majd az életkor előrehaladtával nő, továbbá jellegzetes
klinikai, lokalizáció szerinti és molekuláris eltérést mutathat a nők és a
férfiak között. Epidemiológiai és molekuláris biológiai kutatások eredményei
szerint az ösztradiol (E2) által szabályozott jelútrendszer meghatározó szerepet
játszik a CRC kialakulásában és prognosztikájában, döntően a vastagbélhámban
domináns ösztrogénreceptor-bétán (ERβ) keresztül. Az ösztradiol emésztőrendszeri
hatásai igen sokrétűek, az ép és tumoros vastagbélhámsejtekre gyakorolt hatását
in vitro és in vivo vizsgálatok egyaránt
igazolták. Az ösztrogénreceptor-alfával (ERα) ellentétben az ERβ aktivációja a
sejtosztódást gátolja és az apoptózist fokozza, a béta-receptor kifejeződése
ugyanakkor mind az élettani öregedés, mind a vastagbél kórállapotaiban
megváltozhat. Az ösztradiol ERβ által közvetített daganatellenes hatása a
sejtproliferáció gátlása, az apoptózis serkentése, az áttétképzés gátlása és
gyulladáscsökkentő hatása révén valósulhat meg. Sejtkultúra- és állatkísérletes
kutatások eredményei alapján az ösztrogénreceptor-bétára szelektíven ható
receptormodulátorok (szelektív ösztrogénreceptor-modulátor [SERM]) és a
fitoösztrogének új, hozzáadott kezelési lehetőséget jelenthetnek az idült
gyulladással és a kóros sejtproliferációval jellemezhető colorectalis
megbetegedésekben. Orv Hetil. 2020; 161(14): 532–543.

Background: Failure to thrive (FTT) is a global problem and one of the most common health problems in childhood that involves many other social, economic, and cultural factors. Considering the adverse effects of FTT in the future of children, we studied FTT and its related factor in children under the age of 2 years in Bojnurd (the capital city of North Khorasan province, Iran).
Methods: This study was a Retrospective cohort study on 1000 health records, born in 2008-2013. Stratified sampling method was applied and the data were collected using a checklist in the health centers. Finally, data were analyzed using Chi-square, Multiple logistic regression, and independent t-test in SPSS19 software. Significant level was set at 5%.
Results: Incidence of FTT was calculated as 443 children (44.3%) in the children's first two years of life. A significant relationship was observed between FTT in children and head circumference disorders at birth (p=0.001), maternal age at delivery (p=0.01), mother's education level (OR=0.4 CI95% [0.2-0.8] p=0.012), type of delivery (OR=0.5 CI95% [0.4-0.7] p<0.001), unspecified gestational age (OR=3.6 CI95% [1.3-10.08 p=0.015]), and pregnancy under the age of 18 (OR=2.4 CI95% [1.1-5.3] p=0.02).
Conclusion: Considering the high incidence of FTT in children, increasing awareness about timely feeding, promoting households' health, preventing and controlling infectious diseases should be improved

Published: March 2020

Introduction: Nurses experience more stress than other health care providers due to the nature of their job. Job stress has significant effects on the performance of nurses and health care organizations; it also endangers the health care quality and patients' safety. The purpose of this study was to identify the sources of occupational stress and their relationship with personal and occupational factors among nurses in teaching hospitals of Rasht, a city in north of Iran in 2016.
Methods: This cross-sectional and analytical study was conducted among nurses in the teaching hospitals in Rasht City in 2016. The sample size was estimated based on the Cochran formula. The study population included 250 nurses selected via stratified randomly from the clinical wards in seven hospitals. Data were collected by demographic questionnaire and Toft - Anderson nurses' stress scale including 34 questions in seven domains of nurses' stressors. Data were analysed with independent t, ANOVA, and Pearson correlation coefficient tests using SPSS V21.0 software (Significance level <0.05).
Results: The mean score of job stress (72.46 ± 12.47) was evaluated at the sever level. Based on the findings, 77.8% of the nurses reported that their stress was at the sever level and 21.7% reported a moderate level of stress. The most frequently mentioned sources of stress were related to "uncertainty in treatment", "suffering and death of patients", and "high workload". However, the least source of stress was related to "lack of support resources". Job stress had no significant correlation with personal and occupational characteristics (p> 0.05).
Conclusion: Given the high levels of nurses' job stress, continuous interventions are needed to decrease the nurses' stress at the individual and organizational levels, especially in the highest sources of stress including "uncertainty about treatment" and "workload". In this regard, we recommend the following interventions at primary (related to reducing stressors), secondary (aimed at reducing nurses' response to stressors), and tertiary (focusing on specific assistance to nurses with high levels of stress) levels.

Introduction: Anxiety disorders are common psychiatric disorders in children and adolescents. It seems that the parent-child interaction affects or exacerbates the creation of anxiety disorders in children. The present study aimed to compare the effectiveness of mindfulness and happiness training in promoting parent-child interaction in mothers of anxious preschool children.
Methods: The research method was experimental with a pretest-posttest design and control group. The statistical population included all mothers of pre-school anxious children in Shahrekord in 2018. Using the multistage sampling method, 45 people were selected and put randomly in the control and two experimental groups (n=15 per group). The Spence Children's Anxiety Scale (SCAS) and Pianta's Child-Parent Interaction Questionnaire (PACHIQ) were used for data collection. Experimental groups were put under mindfulness (eight 90-minute sessions) and happiness (ten 90-minute sessions) training, but the control group did not receive any intervention. Analysis of the data involved both inferential and descriptive statistics including mean, standard deviation. Data analysis was conducted using one-way analysis of variance (one-way ANOVA) and analysis of covariance (ANACOVA). SPSS version 24 was further used for analyzing the data. The significance level of research was considered to be α=0.05.
Results: The results indicated that both mindfulness (p=0.0001) and happiness (p=0.0001) training increased parent-child interaction in mothers of anxious preschool children. The mean ± SD of the post-test score of parent-child interaction in the control group was 96.73±7.89 which was significantly different from the experimental groups (p=0.0001). Furthermore, there was no significant difference between the effectiveness of mindfulness (117.80±4.47) and happiness training (115.46±4.65) in promoting parent-child interaction in mothers of anxious children (p=0.599).
Conclusion: Mindfulness and happiness training were effective in improving parent-child interaction in mothers of preschoolers with anxiety and could similarly change the parent-child interaction in mothers of anxious children.

Biosolids generated as waste from a Wastewater Treatment Plant (WTP) are a pollution problem by the provision of large volumes in landfills and the waste of their potential as an agricultural input. The research conducted trials to analyze the agricultural use of biosolids in a food company's WTP, their effects on the germination and development of the vegetal plant species Coriandrum sativum were assessed through trials that mixed different amounts of biosolids, land soil and commercial fertilizer, and took into account: planting site characteristics, biosolid and Coriandrum sativum. A random block design was made to compare treatments understudy and resulted in the combination of 50% biosolids with 50% land soil was the best test by germination, height, mass and length of the roots of the plant studied. In the evaluation of results, the behavior of dependent variables was analyzed: germination, height, mass and length with respect to the four test types with their respective repetitions using ANOVA and Fisher's significant minimum difference (LSD) to determine the effect the biosolid had on the plant and to know the optimal dose for its development. The germination rate (GR) was also determined in the trials, and 98.3% was found for the best treatment indicating that the substrate does not contain phytotoxic elements.

Published: March 2020

Taking the example of Kazakhstan, this study examines the formation and analysis of the cultural media space of the digital generation. Information and communication technologies are the basis of a communicative media environment that has an internal regulated structure, which affects the socialisation of a person. The content of the cultural media space of the digital generation is formed on the basis of digital technologies and represents people’s visual worldview with images, signs and symbols.
The processes of transformation of society affect the young generation and the content of the media space that determines their social and ethnocultural identity. The study presents the results of working with schoolchildren and students aged 14-18 using focus groups to explore the impact of digital culture (media culture) on adolescents in Kazakhstan. Based on the interdisciplinary approach, the findings demonstrate intergenerational contradictions because of the active involvement of Kazakhstan in the global internet community. The cultural media space of Kazakhstan has been shaping the social communications of the digital generation that has grown up in a sovereign state. The theoretical concepts of P. Bourdieu, C. Mannheim and other scientists served as a methodology for this study. Based on the interdisciplinary approach, the findings demonstrate intergenerational contradictions because of the active involvement of Kazakhstan in the global internet community. The findings also unravel that the transformation of the value orientations of adolescents is influenced by the factors of geographical location and ethnicity.
A Concept of Nature in the Modern Animalistic Art of Russia: An Environmental Aspect of the Genre
Authors: Portnova Irina 
Published: March 2020

The study deals with the concept of nature in modern local wildlife art from the perspective of environmental thinking. It is significant in both cultural and artistic aspects. Modern wildlife art has become a vehicle for pressing issues in nature studies and has demonstrated a variety of artistic solutions, creative manners, and approaches, from traditional realistic variants to stylistic interpretations in the spirit of previous epochs. The study reports that the passage of time has caused changes in the historically established genre structure; its boundaries have become vague and the very structure of an artistic image has become polysemic. Nowadays, local art criticism does not cover this issue adequately.
Meanwhile, modern wildlife art represents a bright example of the thematic and stylistic variety of artistic techniques and has a fresh look at the world of animals in its entirety, which refers to a new perception of nature, human attitude to it and supplements the picture of the development of the entire local arts. Against this background, the study of current wildlife issues is quite relevant. The historical and artistic methods allow us to evaluate the originality of animalism, its different sides, in particular genre, species and stylistic diversity, as a characteristic and an iconic phenomenon of modern art, reflecting the concept of “nature" in its ecological perspective. The significance of wildlife art is stressed in moral respect. It is wildlife art, which is closest to nature that organically reflects the picture of the modern world with its current environmental issues and dire ecological situation. The wildlife art of the end of the 19th Century to the beginning of the 21st Century is characterised by the exploration of new vital issues of its time. Therefore, the material given in the article is important for art criticism since it enriches it with a unique perspective of study and in a wider cultural meaning, and, thus, forms a modern philosophical picture of human-nature-animals interrelations.

The purpose of this study is to identify the educational strategies in higher education based on an analysis of students’ motives. The sociological study was conducted using a complex of quantitative and qualitative methods employing a questionnaire survey participated by students, graduate and doctoral students of national and state universities of Kazakhstan. The in-depth interviews were attended only by graduate and doctoral students.
The findings unravelled that the leading motive for education was the desire of students to obtain a diploma. The acquisition of a formal university graduation certificate is important in the opinion of students. However, neither the content or qualifications nor the mastery of the future speciality, which they are going to acquire in the course of study, are not significant motives for the young generation. In the view of modern Kazakhstan youth, to be an educated person means to offer oneself in the labour market profitably.
The existence of a link between the requirements for the future profession and goals in the higher education system was also confirmed in the course of study. The results obtained in the course of research make it possible to head over to a new level of substantiation of educational strategies and create prerequisites for the improvement of the efficiency of the educatory process.
