Authors: Mishra Bhargawi , Gautam Geeta J. , Mishra V. N. 
Published: October 2022

Abstract
Heavy metal load is one of the factor causing deterioration of water quality of rivers and anthropogenic activities being the major cause. Present article is an attempt to evaluate the potential human health risks posed by four heavy metals (Pb, Mn, Cr and Cd). We have estimated the concentration of these heavy metal at different points of river Ganga as well as at confluence point of Ganga and Varuna rivers as follows: Pb 1.29 mg/L, Mn 1.325 mg/L, Cr 0.169 mg/L and Cd 0.161mg/L, which was above than the permissible limits stated by Environment protection agency EPA in drinking water. Randomly seven indigenous species of fishes were collected from the wild and were processed for checking the occurrence of these metals in the tissues such as Gills, Liver and Muscle. In all the seven selected fish species, degree of heavy metal concentration followed liver > gills > muscles. Highest accumulation of Pb was observed in Cyprinus carpio liver (8.86 µg/g) and lowest in Baikari muscles (0.07 µg/g). Total THQ value i.e. hazard index (HI) of metals was calculated for these fish species that are frequently consumed and the data showed HI values in following sequence: C.carpio > O. nilotus > C.punctatus > J.coitor > M.armatus > M.tengara > Baikari. Average HI value for C. carpio and O. nilotus was found above 1 which indicates that intake of heavy metals through these species may cause health hazard for human. Maximum HI was recorded in Carpio, which is highly consumed fish by human, hence may be harmful to them. These findings pose a threat to human population and hence needs regular monitoring of metals in fishes to prevent entry into food chain and its effect on the human beings.

Published: October 2022

The needs of Ukraine’s economic development require the creation of new, innovative technologies that take into account changes in the social and spiritual life of young people, the need to form a harmonious personality and optimize the learning process. New pedagogical technologies are aimed primarily at “providing conditions for self-realization of student’s essential capabilities in various kinds of theoretical and practical activities, in dynamic life in the new market conditions”.
An essential feature of modern innovation processes in the field of education and upbringing is their technologization – a strict compliance with the content and sequence of stages of innovation implementation.
The difference between technology and methodology is a fundamental issue for modern pedagogics. Technology and methodology are distinguished by two main points: the guarantee of the final outcome and planning of the future educational process.
The varieties of personality-centered pedagogical technologies include personality developmental teaching, productive teaching, personalized teaching and technology of higher labor, self-development, technology of humanism.
Analyzing the features of higher pedagogical education technologization, the attention should be paid to an increase in the need for the use of new information technologies in the training of new generation specialists for modern educational systems. New information technologies (NIT) are defined as a set of methods and technological means of collecting, organizing, storing, processing, transmitting and presenting information that increases people’s knowledge and develops their capabilities to manage technological and social problems.
Pedagogical technology is interpreted according to three aspects: the scientific aspect (pedagogical technology as a component of pedagogical science that creates pedagogical processes in pedagogical systems); procedural and descriptive aspect (description, process algorithm, a set of goals, content of methods and means to achieve guaranteed results according to the goal); procedural and effectual aspect (implementation of the technological process, functioning of all personal tools).
Changes in the Oral Microbiocenosis in the Process of Different Adhesive Agents Use for Fixation of Complete Removable Laminar Dentures
Authors: Redushko Yuriy , Kutsyk Roman 
Published: October 2022

The use of adhesives to improve the fixation of complete removable laminar dentures, along with numerous benefits for the patient, creates additional risks of imbalance in some representatives of the oral microflora and, consequently, may cause or maintain the development of prosthetic stomatitis and worsen oral hygiene. Therefore, it is important to study the prevention of disorders of the normobiocenosis of the oral cavity due to the differentiated choice of adhesives based on their antimicrobial activity. The study represents the peculiarities of changes in the oral normomicrobiocenosis in the process of the prescribed adhesives’ use for fixing complete removable laminar dentures.
The aim of the study – is to study the changes in the oral microbiocenosis in the process of adhesives use for fixing complete removable laminar dentures and to assess the effectiveness of their choice based on the results.
Materials and methods of the study. There were examined 120 people, who used full removable laminar dentures, 90 of them used adhesive means prescribed by a dentist for three weeks to improve fixation. All patients were sampled for bacteriological examination. Based on the analysis of culture results for microorganisms in each Group, the constancy index was determined – sowing frequency in percent and population level – colonization mass in lg CFU/ml.
Results of the study. In comparison with persons who did not use adhesives to improve the fixation of removable dentures and data before the study it was determined that the adhesive “Corega” had a preservative effect on the normoflora, reduced the population level of pathogenic coccal microflora, yeasts; adhesive “Laсalut” had an inhibitive effect on all representatives of the normal microflora, reduced sowing frequency and population level of β-hemolytic streptococci, but did not affect the pathogenic activity of Staphylococcus aureus, yeasts and gram-negative bacteria; adhesive “Protefix” had a suppressive effect on the normoflora, did not affect the population level of pathogenic microorganisms and even increased the massiveness of colonization by gram-negative bacteria.
Conclusions. Taking into account the determined changes in the oral microbiocenosis in persons who used adhesives to improve the fixation of complete removable laminar dentures, we can talk about the effectiveness of the adhesive “Сorega” for long-term use in the absence of complications in prosthetic bed tissues and with proper hygienic care of the oral cavity; adhesives “Laсalut” and “Protefix” in patients with existing dysbiotic disorders and with subsequent control of the impact on the resident microflora of the oral cavity.

Authors: Barabash Oleh , Voronych-Semchenko Nataliia , Kryvenkyi Taras 
Published: October 2022

The relevance of the study is conditioned by the prevalence of dental pathology, its complicated course in senior age and the search for the age-associated metabolic markers of oral fluid.
Objective. The aim of the study is: to determine the age peculiarities of the content of nitric oxide and hydrogen sulfide metabolism in the oral fluid of patients, taking into account their dental status.
Materials and Methods. Indicators of nitric oxide metabolism, L-arginine/arginase, hydrogen sulfide content in oral fluid, dental status of different aged people under conditions of intact dentitions, their defects and against the background of correction with different types of dentures, were studied.
Results. It was determined that with age, changes in oral fluid are characterized by an increase in nitrite ion, the amount of nitrites and nitrates, increasing the formation of peroxynitrite against the background of lower levels of L-arginine and hydrogen sulfide, inhibition of arginase activity. The results obtained are confirmed by the presence of close correlations between the concentrations of hydrogen sulfide and peroxynitrite (reverse, strong), caries intensity and: the total level of nitrites and nitrates (direct, strong), peroxynitrite content (direct, medium strength).
Conclusion. The studied biomarkers of oral fluid depend more on age, hygienic condition of the oral cavity, intensity of dental caries and defects of dentitions than types of dentures. Therefore, age-related changes in the biochemical composition of oral fluid, metabolic, somatic, comorbid pathologies are likely to be a trigger for structural-functional disorders of the dental-maxillofacial system.

Published: October 2022

Cardiac diseases, especially chronic heart failure which, according to the World Health Organization, affects 1.5-2% of the global population, are the number one cause of mortality and morbidity worldwide, including Ukraine. Chronic heart failure is often accompanied by endocrine disorders, especially hypothyroidism, the diagnosis of which has increased over the past 10 years, and which facilitates the rapid progression of heart failure due to reduced metabolic processes and altered lipid metabolism.
The objective of the research was to study clinical manifestations, lipid metabolism indicators and their relationship in patients with chronic heart failure of ischemic genesis and coexisting primary hypothyroidism.
Materials and Methods. 73 patients with the average age of 55.92±2.66 years were examined. They were divided into 2 groups: Group I included 38 patients with chronic heart failure and coexisting hypothyroidism; Group II comprised 35 heart failure patients without hypothyroidism. The clinical course of chronic heart failure itself and chronic heart failure with coexisting hypothyroidism was studied, the patients’ quality of life was evaluated, the myocardial function was studied by means of the 6-minute walk test, the indicators of lipid profile were analyzed by determining the serum levels of total cholesterol, low-density lipoprotein cholesterol. To assess thyroid function, thyroid-stimulating hormone and thyroxine levels were determined by the electrochemiluminescence immunoassay.
Results and Discussion. The clinical course and quality of life of patients with chronic heart failure and coexisting hypothyroidism were worse as compared to patients without hypothyroidism. The serum levels of total cholesterol, low-density lipoprotein cholesterol differed between both groups of patients (p<0.05).
Conclusions. Blood lipid profile was more significantly impaired in the patients with chronic heart failure of ischemic genesis and coexisting primary hypothyroidism that could result in the rapid progression of chronic heart failure, a more severe clinical course, and more frequent complications. The quality of life was higher in patients with heart failure without hypothyroidism and their condition was significantly better.

Published: October 2022

SUMMARY

Purpose
This study aimed to determine the radiant exitance of new, damaged, and 16-year-old light-curing units (LCUs) with and without infection control barriers, and before and after removal of any debris.

Methods and Materials
Old LCUs consisted of 62 SmartLite iQ2 lights (Dentsply Sirona, York, PA). New LCUs consisted of 58 SmartLite Focus (Dentsply Sirona) and 58 Valo Grand (Ultradent, South Jordan, UT, USA) LCUs. Each LCU was examined for damage and debris on its tip. A handheld radiometer (CheckUp with BlueLight Analytics app, Halifax, Nova Scotia, Canada ) was used to measure the radiant exitance using a 10-second exposure time. Measurements were made with and without infection control barriers. If debris was present, the radiant exitance was measured before and after removal of debris with and without the barriers. All measurements were repeated three times. The means of the measurements were used for statistical analyses, which consisted of paired t-tests, analysis of variance (ANOVA), and Tukey post-hoc analyses conducted with a 0.05 level of significance.

Results
Infection control barriers significantly reduced the radiant exitance of all LCUs, ranging from 4.35% to 6.91% depending upon the LCU and the presence of debris or damage. Clean undamaged SmartLite Focus (907 mW/cm2) and Valo Grand (Ultradent) LCUs (883 mW/cm2) with barriers had statistically higher radiant exitance than older clean undamaged SmartLite iQ2 (Dentsply Sirona) LCUs (719 mW/cm2) with barriers. All LCUs exceeded the recommended 400 mW/cm2 radiant power to cure 2 mm of Filtek Supreme Ultra shade A2 composite resin (3M ESPE, St Paul MN, USA).

Conclusion
Infection control barriers, debris, damage, and age all significantly reduced radiant exitance of the lights.
Association Between Secure Attachment Style and Subjective Well-being: Examining the sequential mediation effects
Authors: Mittal Ella , Rani Tamanna 
Published: October 2022

Attachments are an integral element of the human experience from birth to death. Early experiences with caregiver and adult attachments are crucial for human emotional and cognitive development and it is a strong basis for mental health and psychological adjustment. Despite this, little research on the relationship of these attachments has been undertaken on subjective well-being.
This study intended to investigate the relation of secure attachment style with subjective well-being through serial mediation effect of self-esteem and emotional intelligence. Process macro version 3.4 in SPSS 23 and AMOS 21.0 were used to evaluate survey data of 266 respondents.
The findings of the study revealed that secure attachment style play a significant role in enhancing the subjective well-being of people and a positive significant relation was found between them. Also, this relationship was mediated by both self-esteem and emotional intelligence which supports the serial mediation model. Hence, the results exhibit that secure attachment style predicts self-esteem and emotional intelligence, which in turn influences the subjective well-being of persons. Furthermore, both direct and indirect effects were statistically significant.
Theoretical and practical implications are discussed based on the findings of the study.

Authors: Ugwuozor Felix Okechukwu 
Published: October 2022

Following Professor Obiora Ike’s view and in particular Obiora 2012, 2013, 2017 (see reference below), the more students are exposed to ethics practice, the greater their propensity and capability to seek for ethical living. This important assumption is worth close statistical scrutiny as the author shows. Through empirical researches and the stratified sampling approach, 435 university students are randomly selected to illustrate this claim. The method used is the “Perceived Role of Ethics and Democracy Outcome Scale” (PREDOS) and a survey questionnaire used to measure exposure to common good ethics among the respondents. Descriptive analysis – tables and analysis and covariance (ANCOVA), are aimed at facilitating the analysis of the data collected in the study. In tandem with the conclusions drawn from extant literature and works of Professor Obiora Ike, the findings, as the author see, show that exposure to common good ethics has a significant positive effect on students’ ethics practice and democracy outcomes.

Published: October 2022

In regard to the current innovation on multi-dimensional learning systems in industrial era 4.0, teachers and educators worldwide strive for students to have a strong foundation in mastering English, one of which is speaking skills. Teachers help students build self-confidence and provide innovative technology that enables them to practice and focus on their own unique needs outside the classroom. There are alternatives to bring these goals into reality: first is to create a positive, fun learning environment both at school and at home. Second, to provide new experiences for students to directly interact with foreigners who teach and use English as their first language. This research investigatesstudents’ speaking skills in the lower-class group of elementary school (28 second graders, aged seven to eight years old). The study also thoroughly explored how foreign teachers’ fun activities during classroom hours can affect students’ speaking. In order to find answers to the research problems, simple conversation to test the speaking ability was conducted. After the test, the teacher helped students fill out a questionnaire to know their perception of learning with foreign teachers and their opinion on doing interactive games and outdoor activities during classroom-hour. The speaking ability of the second graders in SD Negeri Jember Lor 3 is sufficient, and they can pronounce some vocabularies correctly and conduct simple conversations with foreigners. The adequate mastery of the conversation may be following the pattern of various determinants, especially factors concerning the help from foreign teachers who model pronunciation, sentence stress, grammar, intonation, and vocabulary in a valid and veritable accent.
