Knowledge and interest of north-central Romanian mothers regarding children oral health prevention - A questionnaire based study
Authors: Tohati Adrian , Bechir Farah 
Published: October 2020

Abstract
Introduction: The development and eruption of teeth should be followed by the dentist, which is why periodic check ups are required.
Aims of the study: This study aims to evaluate the knowledge of the mothers regarding the dental hygiene of the children and the importance of presenting them in the dental office, as well as the knowledge related to the prevention of dental caries.
Material and Methods: A questionnaire comprising 15 questions was developed and handed to 290 mothers in Tirgu Mures. The questions targeted the knowledge related to the dental hygiene of the child, and decay prevention.
The data obtained were processed electronically. 51.7% of the mothers stated that the visit to the dental office should be done every 6 months, and 58.6% opted for a first contact with the dentist at the age of 3 years. 98.2% of mothers consider dental prevention to be important or very important. 75% consider that the child’s hygiene must be done twice daily, and 89% said that they use the toothbrush in the child’s hygiene process. 68% of the mothers know the term of dental sealing, but only 20% resorted to this method of treatment.
Conclussions: The study demonstrates the urgent need to take the lack of interest and information of parents seriously and to develop programs primarily to inform and raise awareness of the population and then to apply different preventive methods.
Determination of Stress Values in the Surface Layer of Inconel 718 Samples Dedicated to Fatigue Tests
Authors: Gadalińska Elżbieta , Michałowski Andrzej , Czarnewicz Sławomir 
Published: October 2020

Abstract
This work deals with the problem of X-ray stress determination on the samples dedicated to fatigue tests. A number of research studies point out the fact that the processing of hard, difficult to machine materials like nickel superalloys, reveals more than one trend of residual stress versus working parameters of behaviour (Lavella and Berruti, 2010). Many papers have shown that the residual stresses are dependent on a combination of a number of factors. When the above is taken into account simultaneously with the requirements of the internal General Electric specification for the fatigue tests samples preparation (Metallic test specimen preparation, low stress, 2017) the problem of turning and grinding parameters gathers significance. It is well known that the quality of the surface layer, produced during machining, is of vital importance for the fatigue life specially for the components of aircraft produced form nickel superalloys e.g. Inconel 718 (Kortabarri et al., 2011). That is why the surface layer’s properties are described in detail by the standards. The aim of the work is to determine one of the most influential features from the point of view of fatigue life, i.e. the stress state on the surface layer with one non-destructive method – the diffraction analysis.

Lake Ladoga Digital Bathymetric Models: Development Approaches and Insight for Limnological Investigations
Authors: Naumenko Mikhail A. 
Published: October 2020

Abstract
The creation of digital bathymetric models (DBM) of lakes allows not only for storage of the data on depths and shorelines in a standard format, but also for the estimation of the major morphometric characteristics of the reservoirs. To calculate the water, thermal, and chemical budgets of large lakes, it is important to know their hypsometry. We developed a new digital model of Lake Ladoga, the largest European lake, which was done to identify and correct topographic data errors, as well as to identify more depth points. The produced bathymetric model of the lake allowed for the updating of morphometric characteristics. The lake-bottom grid of 0.5×0.5 km with 70190 depth points of interest was produced using the kriging procedure with the mean error ME = 0.05 m and root mean square error RMSE = 5.6 m. The statistical characteristics of the lake depth and slope are determined on the basis of the advanced digital model of the lakebed relief. The form of the lake depression corresponds to the convex type (microtype) and bears some similarity to lakes Erie, Huron, Vanern, and Malaren. We describe how the bathymetric model has been developed and the morphometric characteristics of the lake have been corrected. We also discuss the results of its application in limnological investigations. A relationship has been established between surface water temperature, transparency and the bottom depths for the various seasons of Lake Ladoga.
Émile Durkheim and the Longing for Community Life
Authors: Kostyło Piotr 
Published: October 2020

Summary
This article analyzes the problems of community life as explored in Emile Durkheim’s texts, particularly his lectures published under the title Moral Education. The starting point is the tension, characteristic of modern society, between the need to express one’s self within the community and the need to assert individual autonomy. The thesis presented here is that Durkheim looks for the sources of contemporary community life through the impact of school and professional groups, instead of the traditional influence of the family and Church. The article examines Durkheim’s argumentation relevant to justifying the thesis. In the final point, two lines of criticism of the Durkheimian concept, the spiritual and the Marxist, are deemed moot, as is the line of comparison between Durkheim’s approach and Zbigniew Kwieciński’s concept of community life.
Interpersonal Trust in the Working Environment. A Theoretical Analysis
Authors: Piorunek Magdalena 
Published: October 2020

Summary
The paper Interpersonal Trust in the Working Environment. A Theoretical Analysis describes the phenomenon of trust in social relations, provides definitions and types of trust, explains the conditions necessary for the development of trust, and discusses the relational and personality-related aspects of trust. It also reviews the interdisciplinary literature on the subject of trust, providing a multidimensional description of trust in the workplace, in organizations. Vertical and horizontal trust in organizations is described. Presenting some trust-building models in businesses, the paper selectively describes the consequences resulting from trust vs a lack of trust in the working environment. It identifies the culture of trust and employee empowerment as desired models promoting the development of workplace relations and addresses some controversies that disrupt the functional adaptation of employees to the reality of knowledge-based organizations in the post-modern social reality.
Child Protection in the Event of Parents’ Divorce – Conceptualization of the Subject of the Study
Authors: Turczyk Małgorzata 
Published: October 2020

Summary
The article is preconceptual in its nature, as it is an introduction to a planned research project in the area of pedagogy and law. The author describes the research in current trends in modern childhood studies, choosing the protection of children’s rights in the event of their parents’ separation as the basic research category. This category will be analyzed in ontological, epistemological and methodological dimensions. In view of the growing scale of family breakdowns, it becomes justified to ask a question about the way of experiencing, understanding and constructing knowledge about the subject of pedagogical and legal interactions – the child themself. Building knowledge about a child whose parents separate is not only intended to expand and build interdisciplinary theoretical knowledge, but also to provide a basis for designing adequate tools and activities to protect the rights of a child experiencing their parents’ separation. This article provides an outline of a research concept aimed at protecting children’s rights. The article contains extensive justifications for the research topic and the framework of the methodological concept.

Combined application of press mud compost and inorganic fertilizers is a cost effective way to manage soil fertility in a sustainable way. To evaluate the results of press mud compost and inorganic based synthetic fertilizers, the present study was planned and research was conducted at Sheikhoo Sugarcane Research Farm located at Sheikhoo Sugar Mills, Kot Addu. The experiment was consist of six treatments namely T1 = No fertilizer, T2 = NPK 228-114-124 kg ha-1, T3 = 25 t ha-1 compost, T4 = NPK 228-114-124 kg ha-1+ 20 t ha-1 compost, T5 = NPK 114-57-62 kg ha-1+ 20 t ha-1 compost and T6 = NPK 228-114-124 kg ha-1+ 10 t ha-1 compost and was laid out in RCB design having four replications with a net plot size of 6 m x 8 m. Sugarcane growth and yield parameters including soil fertility levels (pre planting and post harvesting) were studied. Results showed that lower pH value (8.42) and higher organic matter contents (0.42) were recorded in treatment having compost @ 25 t ha-1. Whereas, higher N (0.028 %), P (7.27 ppm) and K (68.25 ppm) were found in those soils which were treated with NPK 228-114-124 kg ha-1+ 20 t ha-1 compost. Results regarding sugarcane growth and yield showed that maximum number of tillers (138.50 x103 ha-1) 135 days after planting, number of millable cane (104.25 x103 ha-1), number of nodes (25.25/ cane), cane girth (7.54 cm), cane length (3.89 m), cane yield (111.75 t ha-1), brix (22.08 %), pol (19.80 %) and sugar recovery (10.75 %) were observed in those plots treated with NPK 228-114-124 kg ha-1+ 20 t ha-1 compost. It can be concluded that the combined use of press mud compost and inorganic NPK fertilizers remained successful to promote the growth as well as the yield of sugarcane and soil fertility improvement in an efficient way.

DFT B3LYP/6-31G* level data on energetics is reported for drug-receptor interaction.Several FDA approved drugs and traditional herbal isolates are modelled.Used Gaussian16 to model the systems.The interface cavity of SARS-CoV-2 S-protein:human ACE2 complex (M) for ligand (L) binding is modelled using a two layer ONIOM(B3LYP/6-31G*:PM7) method for sixteen traditional herbal isolates (THI) and nineteen drugs. The binding energy (Eb) of ML complexes increased with increase in dipole moment of Ls. Eb better than -80.0 kcal/mol is observed for digallic acid and adenosine 3',5'-bisphosphate whereas myricetin, glucogallin, sapropterin, tetrahydrobiopterin, protirelin and fidarestat showed Eb better than -60.0 kcal/mol. Multiple noncovalent interactions emanating from arginine, histidine, tyrosine, lysine, carboxylate and amide units (total around 6 - 8) of L, S-protein and ACE2 receptors provide the high binding energy. The sugar substitute aspartame modified with myricetin unit showed the best Eb -91.7 kcal/mol. ONIOM-linked DFT study is effective, affordable and reliable for a quantum chemical rational design approach to model drug-receptor binding process for COVID-19 drug development which sheds light upon the noncovalent binding features of receptor cavity.

Published: October 2020

Introduction: Eyelid tumor refers to the primary eyelid skin and accessory tumors, which not only affects the appearance and vision, and even local infiltration and distant metastasis, thereby threatening life. Surgical resection is the most important and effective treatment, but tumor resection often leads to a wide range of eyelid defects, significantly affecting the shape and function of the eyelid. Therefore, the eyelid defect must be repaired after resection to achieve the purpose of aesthetic appearance and protection of the eyeball. The objective of the study was to analyze the clinical results of local flap transfer and scleral transplantation in repairing skin defect after eyelid tumor operation.
Methods: Forty patients with postoperative skin defects of eyelid tumors admitted from December 2008 to December 2018 were taken for analysis and divided into two groups, 20 cases in each group. The control group underwent autologous lip mucous membrane transfer and nearby skin flap, while the experimental group received local skin flap rotation and scleral allograft repair. The clinical effect of repair of the two groups were compared.
Results: In the experimental group, the effect of clinical repairs were better, the difference of height of palpebralfissure and the length of palpebral fissure were compared with the control group, which showed statistical significance favoring the experimental group.
Conclusion: Local flap transfer and scleral transplantation has better clinical outcome to repair the skin defect after operation of eyelid tumor.
