Authors: Kaskova L.F. , Yanko N.V. , Kulai O.O. 
Published: March 2021

A paradigm shift in dental caries treatment in paediatric dentistry is viewed towards a wide using of composite resins. This prospective clinical trial are evaluated and compared during 18 months of clinical performance of a microhybrid composite with a nanoceramic resin composite placed in сlass I and II cavities in permanent teeth in children.
Thirty one children aged between 7 and 15 years were investigated during this study. About 40 restorations were performed, 50% for each material: a nanoceramic resin composite “Ceram. X Sphere TEC one” and a microhybrid resin composite “Charisma”. The restorations have been estimated by investigators immediately after complete polishing a filling. Clinical evaluation was performed 18 months after replacement by two other investigators using modified USPHS criteria. In addition to hand instruments, a magnifier was used for investigation of the restoration margins. Eighteen fillings with “Ceram. X Sphere TEC one” and 17 fillings with “Charisma” were available. The USPHS parameters were analyzed with the Chi-square test in18 months. The level of significance was p<0.05. Also Green-Vermillion index was used for oral hygiene estimation.
There are no failed restorations and secondary caries during the studied period. There were no statistically significant differences among the materials used (p>0.5) regarding the clinical performance. Green-Vermillion hygienic index was 1.48. Thirteen children (43.42%) showed satisfactory level of oral hygiene, 10 children (35.71%) demonstrated good level and 7 children (20.87%) – unsatisfactory level.
According to the marginal discoloration and surface roughness criteria, there were no significant differences among the restorative materials (p>0.5). Marginal discoloration was seen in children with unsatisfactory oral hygiene that corresponds to the data of recent study. Marginal adaptation rate was 94.95% for nanoceramic, and 82.35% for the microhybrid restorations. The marginal defects recorded had small detectable defects at the enamel margin of the restorations. According to the anatomic form criterion, there were no significant differences among the restorative materials (p>0.5).
Postoperative sensitivity of one nanoceramic and two microhybrid restorations was scored as Bravo at baseline examination, but it disappeared by the 18-months evaluation. For color match criterion, the slight differences were observed in microhybrid restoration in 18 months. This shade mismatch was clinically acceptable (Bravo), with no significant differences noted between the materials studied (p>0.5).
The nanoceramic and microhybrid composites have provided acceptable clinical performance over 18-months period. The research pertaining to bigger size of a studied sample and longer observation period is considered advisable to ensure the higher clinical success rate of nanoceramic than microhybrid composite in restoration of permanent teeth in children.

A study of aspects of the use of smart technologies in construction. This technology originated in the IT industry with the advent of digital devices. Until now, this technology has been invested primarily in the concept of "smart home" with digital control technologies. Then smart technologies spread to the technology of energy-efficient housing and its maintenance. Today, this technology also includes technologies of ecological and energy-saving construction, i.e. smart technologies for the construction of, first of all, modular. Thus, smart technology in construction in any sense means the organization of "smart", i.e. healthy, economical, safe and comfortable human housing at all stages of its life cycle. The surge in interest in "smart" homes and technology is a consequence of the global "digitalization" of human life. In 2017, Ukraine adopted the Law “On Energy Efficiency of Buildings”, which defines the legal, socio-economic and organizational principles of activities in the field of energy efficiency of buildings and aims to reduce energy consumption in buildings. This law defines the basic principles of state policy of Ukraine in this area, namely: ensuring the appropriate level of energy efficiency of buildings in accordance with technical regulations, national standards, norms and rules; stimulating the reduction of energy consumption in buildings; ensuring the reduction of greenhouse gas emissions into the atmosphere; creating conditions for attracting investments in order to implement measures to ensure increase the energy efficiency of buildings; ensuring thermal modernization of buildings, stimulating the use of renewable energy sources; development and implementation of a national plan to increase the number of buildings with close to zero energy consumption. The article considers five areas of implementation of these requirements - energy independence, environmental friendliness, comfort, economy and safety.
Most effectively, in terms of minimizing the components of the technological process, and the cost-effectiveness of the implemented project, these principles can be implemented using materials and technologies that can integrate these requirements in one complex. When implementing the requirements laid down in the above four areas when using smart technologies in construction as a material that combines these areas, it is possible to provide products based on basalt fiber-rigid and semi-rigid thermal insulation boards, mats, harnesses and other materials. These materials can be used in the development of part of the requirements of the fifth direction - security. They are implemented in the development of environmental safety of housing, fire resistance of the building, biological safety of the material, indoor air quality and other aspects of smart technologies.

One of the important tasks for Ukraine is to restore navigation on the mouth of the Danube Bistre, using it as a European-Asian way from the Baltic Sea to the Black Sea, and then to the East. Restoration of the deep-sea navigation of the Danube-Black Sea River has begun about ten years ago and has been progressing with great difficulty and interruptions. A protective enclosing dam of the Maritime approach channel of the Danube-Black Sea deep-water vessel was built in the water area of the Bystre estuary of the Kiliya Delta of the Danube River. This paper presents the results of mathematical and physical modeling of the improvement and reconstruction of the protection dam of the Maritime approach channel of the Danube-Black Sea deep-sea navigation. Numerical calculations of the transformation of wind waves in the water area near the dam for the most dangerous wind directions in stormy conditions are carried out. For mathematical modeling, the maximum values of wind and wave height were used, which were observed during the entire research period in the area of the dam. Within the framework of refraction theory, wave transformation calculations were performed for the most wave-dangerous directions of wind acceleration, namely, northeast, east, southeast and south wind directions. The results of calculations show that the construction of a protective dam at the exit of the Bystre estuary leads to a significant reduction in wave heights (almost twice) and their lengths by more than 1.5 times, which will ensure a smooth approach and exit of vessels to the Bystre estuary. To assess the characteristics of storm surges and wind waves in the study area was set "hypothetical" storm, when uniform in space and constant in time wind blows over the entire Black Sea. Simulations of wind waves were performed by the 3-step method of nested grids. Calculations were performed for twelve options directly. The morphodynamic calculations showed the areas of circulating near bottom currents inside the dam protected area and the peculiarities of the bottom deformation due to wave motion and storm rise of sea level. Experimental studies on a fragment of the dam model revealed the areas of greatest wave loads, features of wave transformation and pressure fields on the dam ridge. On the basis of theoretical and experimental researches the new step form of the dam which withstands storm wave loads is proposed.
Research on the Perfection of Disregard of Corporate Personality in Enforcement
Authors: Wang Pu 
Published: March 2021

China's current disregard of corporate personality system has several prominent problems in the mandatory enforcement procedures, such as different identification standards, difficulty in starting the enforcement procedures, and lack of supporting systems. Perfecting the application of the disregard of corporate personality system in the enforcement process can effectively alleviate the "execution difficulty" problem to a certain extent. In judicial practice, to solve the problem of difficult implementation of the main body of the company caused by the control of shareholders' abuse of the company's independent personality, on the one hand, it is necessary to improve China's company law and other related legal systems, formulate supporting standards, and incorporate the common circumstances of corporate legal personality denial into judicial interpretation. On the other hand, we should strictly grasp the scale in the execution procedure and deny the person who abuses the company's independent personality.
