Reconstruction of Land Exertion for Investment
Authors: Sumardi Juajir
Published: April 2021

This study aims to determine the basis of welfare, so the nature of investment in land is placed in the basic values ​​of Pancasila and the 1945 Constitution. The type of research used is normative legal research using a statutory approach. The results show that the concept of diversion through the principle of restorative justice for criminal acts against property has actually been practiced by indigenous peoples in Indonesia since ancient times and is still practiced today, but in the Indonesian legal system or the criminal justice system has not been explicitly regulated in statute form. The use, application and regulation are still at the level of discretion in each law enforcement agency in accordance with the internal rules that bind the respective law enforcement agencies. For this reason, to implement the values ​​contained in Pancasila and the mandate of the state constitution, economic law in the investment sector must be directed at encouraging balanced economic growth, prosperity, and equal distribution of opportunities. In this regard, the obligation to have social and environmental responsibility must be implemented in any investment activity that uses the land as a production factor by giving local governments the role of supervising the implementation level.

DETERMINATION OF EFFECTIVE METHODS AND METHODS OF DELIVERY OF EDUCATION TO STUDENTS
Authors: Khasanov I. B.
Published: April 2021

We discussed the problems of choosing effective methods and methods of delivering education to students in the paper. This process is very complex and contains a huge range of interacting variables. Nowadays, there is no adequate theory or process to determine effective methods and methods for delivering education to students. As a rule, it is assumed that individual learning is the default option, because of its superiority, and
online learning is used only when circumstances do not allow the use of individual learning. However, online learning has become very common and effective in many contexts. Fully online courses are suitable for some types of students better than others: older, more mature students; students with an already high level of education; part-time students who work or with families. In terms of blended learning, the criteria are less clearly defined
than for fully online learning. These courses are more suitable for more experienced students with strong motivation. In general, online students need more self-discipline in learning and more motivation to learn to succeed. This does not mean that other types of students cannot benefit from online learning, but additional efforts must be made to develop and support such students on the Internet. In terms of blended learning, the criteria are less clearly defined than for fully online learning. The advantage for students is to increase flexibility, but they should still live close to the educational institution, since this model means attending classes at the university. In addition, blended learning enables the gradual development of self-learning skills, if it is a focused learning strategy. Research also suggests that self-study skills need to be developed while students are at university. In
other words, online learning in the form of blended learning should be deliberately introduced and gradually expanded as students work on the training program, so by the time they graduate, they acquire the skills necessary for self-study, which is critical in the digital age .Based on the study, steps are suggested for choosing the necessary method and method of delivering education to students.
THE RELATIONSHIP OF INTERACTIVE COMPETENCE WITH VALUE ORIENTATIONS OF STUDENTS OF TECHNICAL UNIVERSITY
Authors: Selivanova S. A.
Published: April 2021

The aim of the study is to identify the relationship of interactive competence and value orientations of technical college students. Research methods – testing on the basis of test questionnaires: “Diagnosis of perceptual-interactive competence N.P. Fetiskin”; “Diagnostics of the real structure of value orientations of a person” (S. S. Bubnova). The empirical base of the study is 350 students of Moscow Technical University. In the course of the correlation analysis, a number of interrelations between the components of interactive competence and value orientations of students of a technical college were revealed. The higher the degree of adequacy of the assessment of personal characteristics of partners in interaction (mutual understanding), the more important are communication, love, respect for people and at the same time the importance of the ability to influence others and manage others, high social status and health increases. The higher the personality’s ability to understand the point of view of a communication partner and the desire to present one’s own point of view for evaluation and understanding by others (mutual understanding), the more important for such a person are health, love, communication with other people, at the same time respect and recognition from others, influence and management of people, high social status. The higher the degree of significance of the manifestations of others, the ability to regulate their own behavior and the ability to self-analyze a person (mutual influence), the more significant are love, help and mercy in others, communication, health, knowledge of the new in the world, nature, man, high social status and managing people, recognizing and respecting people and influencing others, social activism to achieve positive changes in society. The higher the significance of the personal position in joint activities (social autonomy), the more significant the cognition of the surrounding reality, compassion and help to people and less importantly pleasant pastime, rest. The higher the satisfaction with their position in the group, the orientation towards flexibility of behavior and contact within and outside the team (social adaptability), the more significant are love, high social status and management of people, recognition and respect of people and influence on others, social activity for achieving positive changes in society, health. The higher the focus on the effectiveness of joint activities (social activity), the more significant are the search and enjoyment of the beautiful, help and mercy for other people, love, high social status and management of people, recognition and respect of people and influence on others; communication, health. Thus, value orientations are an important component of enhancing online competence.
THE SUBJECT TERMINOLOGICAL LITERACY OF THE TEACHERS OF LIFE SAFETY AS SUCCESS FACTOR OF THEIR PROFESSIONAL SOCIALIZATION
Authors: Kropotova N. V.
Published: April 2021

In article features of subject conceptual and terminological training of teachers in the field of life safety as important condition of their professional socialization are discussed. Professional socialization of students is a complex process of their integration into professional assemblage on the basis of mastering of professional experience and professional culture. The important role in this process is played by professional communications, to master which without knowledge of «professional language» it is impossible. Free possession of professional concepts and technical terms is real professional skill and an obligatory condition of personal and professional growth, that allows to react confidently in professional environment. Thus success of professional socialization of students during higher school training is largely defined by their readiness for using effective professional communications. The content of concrete vocational training of teachers of life safety is introduced by three «thematic lines» — safety in extreme situations, medical and biologic bases of life safety, extreme situations of social character and protection against them. Each thematic line forms, uses and enriches own terminological field. These terminological fields are sated by flock of various concepts and consequently require the enhanced training on their mastering. In the modular undergraduate program students form their terminological literacy, while the Master program is directed on developing the students’ terminological competence. The selection of methods and relevant educational technologies in the field of learning professional terminology was carried out in the course of studying of subject matters taking into account their specificity and academic semester.

Published: April 2021

This paper examines and analyzes the history of the development of the sanatorium and tourism industry in the Crimea, analyzes the sanatorium and resort complexes of the southern coast of Crimea and gives recommendations for their reconstruction. The paper highlights 5 characteristic periods of development of the Spa industry in the Crimea. The first period-the beginning of the XIX century. - 1917-the time of origin of the sanatorium and tourism industry in the Crimea. The appearance of the first Crimean resorts and sanatoriums mud treatment in Saki. During this period, opened: boarding house "Darsan" (1897, Yalta), sanatorium in honor of the Emperor Alexander III (1900, village. Massandra), sanatorium. Empress Maria Feodorovna (1910, Yalta). The second period-1917-1944 - was the period of formation of the socialist system of Spa treatment and recreation. At this time, palaces, cottages, mansions were given over to sanatoriums for workers and peasants. The third period-1944-1950 (post-war time) - the period of restoration of sanatorium-resort complexes. The fourth period – 1951-1990. during this period, a powerful system of planned recreation and tourism was formed in the Crimea. The fifth period-1991 – present. Since the late 90's, the number of private boarding houses, recreation centers, and hotels has increased significantly. However, many of them do not meet regulatory requirements, international standards and expectations of tourists. Considered Spa complexes are located on the territory of the southern coast of Crimea. These institutions are United by one feature: the presence in its composition of cultural heritage and buildings of the Soviet period, which do not have artistic expression. The article analyzes the shortcomings of Spa complexes and gives recommendations for their reconstruction.
MODELING ARCHITECTURAL FORM SURFACE DEPENDENT SECTIONS
Authors: Chekalin A. A. , Reshetnikov M. K. , Shpilev V. V. , Borodulina S. V. , Ryazanov S. A.
Published: April 2021

For the design of surfaces in architecture, as a rule, universal techniques developed for other technical industries are used. First of all, these are general kinematic surfaces and interpolation cubic splines for modeling complex piecewise smooth surfaces. The authors propose to use the fourth degree inerodifferential spline developed by them for problems of geometric modeling of architectural forms. For calculations and constructions on a computer, the proposed spline is not much more complicated than traditional cubic splines, since it has one additional parameter - a coefficient. However, this allows you to locally control the shape of a curve or surface during design, that is, to change the shape in individual areas without affecting other areas. The article proposes a method for constructing a geometric model of the kinematic surface of dependent sections with a fourth degree parabola as a generator. When using cubic splines as a guide, the surface is a 3 × 4 non-uniform (heterogeneous) spline. The article shows that the surface on the basis of the proposed mathematical apparatus can be composite piecewise-smooth. A particular case of surface design is considered on the example of creating a model of the surface of the facade of a residential building according to the existing concept. The algorithm can be easily programmed and added as a tool to existing CAD systems.
USE OF PHOTOELECTRIC MODULES WITH DOUBLE-SIDED RECEIVING SURFACE FOR SMALL GENERATION UNITS
Authors: Kuvshinov V. V. , Bekirov E. A. , Guseva E. V.
Published: April 2021

In the presented work, the possibility of using photovoltaic silicon panels with a double-sided arrangement of solar cells on the front and back sides is presented. With a lack of space for placing solar panels, these types of modules can significantly increase the generation of electrical energy. Equipping photovoltaic systems with rechargeable batteries contributes to a more rational consumption of electrical energy, while energy storage systems significantly increase the efficiency of solar generating systems. The proposed designs are intended to increase the power characteristics of solar energy converters in the winter months, in the presence of snow or when using reflective surfaces on road surfaces. The results of the experimental studies have shown a significant efficiency of the proposed designs, as well as an increase in the total generation of electrical energy. With the development of the global technical potential and a significant increase in the production of power plants for solar energy, a new opportunity has emerged to use combined solar plants for photovoltaic conversion of the flux of incident solar radiation. At the Department of Renewable Energy Sources and Electrical Systems and Networks at Sevastopol State University, at the site of the Institute of Nuclear Energy and Industry, a photovoltaic installation was developed and studied, consisting of two side silicon solar cells and energy storage systems. The article presents the results of experimental and theoretical studies, presents diagrams, drawings and graphs of various characteristics of the FSM-110D photovoltaic panel and storage batteries. The research results show the increased efficiency of the proposed installation, as well as a good possibility of using the presented photovoltaic systems to provide them with autonomous and individual consumers living in the Crimean region and the city of Sevastopol.

Authors: Elumeeva T. G. , Cherednichenko O. V. , Gavrilova T. M.
Published: April 2021

The rate of plant litter decomposition depends on two simultaneous processes: the decomposition and stabilization of organic matter. To compare the rates of these processes in various ecosystems now a Tea Bag Index (TBI) is widely used. The samples of standard material (green tea and rooibos) were buried into soil at the depth of 8 cm in four herbaceous plant communities of Central Forest State Nature Biosphere Reserve (CFSNBR) and seven communities of the Moscow river floodplain near the MSU Zvenigorod biological station (ZBS). Considering the mass losses of samples during the incubation time we calculated the values of decomposition constant and stabilization factor according to the protocol by J. A. Keuskamp et al. (2013) and estimated the links of these parameters with Ellenberg’s ecological indicator values. The stabilization factor values ranged from 0.122 g/g in Filipendula community of CFSNBR to 0.379 g/g at the natural levee of the Moscow river, and the decomposition constant values ranged from 0.0089 g/g/day in Filipendula community of CFSNBR to 0.0308 g/g/day at the slope of the high floodplain. The mean values of these parameters were significantly positively correlated. The decomposition rate was lower in the communities of CFSNBR and was positively correlated with the soil pH Ellenberg’s indicator values. The stabilization factor values did not depend on the region and decreased with the increase in soil moisture and nitrogen. The mainland meadows of CFSNBR and the meadows of the high floodplain of the Moscow river, belonging to Cynosurion cristati alliance, had the most similar parameters of decomposition.
ENVIRONMENTAL MANAGEMENT AND AQUATIC ECOLOGY IN SEARCH OF ANSWERS TO THE CHALLENGES OF THE TIME
Authors: Shadrin N. V. , Anufriieva E. V.
Published: April 2021

Currently, the destruction of landscapes is taking place with a decrease in the sustainability and productivity of natural ecosystems. One of the main reasons for this is inadequate environmental management, which, as a rule, is based on inadequate outdated theoretical ecological concepts. The totality of accumulated data shows that real ecosystems can be in several alternative states and demonstrate relatively rapid changes in the regime of existence with significant, abrupt and permanent changes in structure and functioning. In this regard, the main ecosystem paradigm is currently being revised. From the theoretical concept of the unicity of the ecosystem stable state, ecology moves to the concept of the multiplicity of stable states in the ecosystem. The dynamics of ecosystems can be represented, according to K. Holling, in the form of an adaptation cycle with the alternation of four phases, the features of which are considered. The importance of no return points and possible uncertainty in the dynamics of ecosystems are shown. Ecosystems, in a certain sense, have memory, which is the reason for the hysteresis effect during multidirectional changes in systems. The necessity of developing approaches of adaptive ecosystem management based on this concept is shown. Which is especially important in cases of rapid transformation of natural ecosystems, such, as an example, in the Crimea after the cessation of the supply of Dnieper water to the North Crimean canal. The difficulties of transition to adaptive environmental management in modern conditions are analyzed.

The taxonomic diversity and current condition of the higher crustaceans, which live on the loose littoral and sublittoral bottoms of the bay, was assessed. 41 species of Malacostraca have been identified. They belong to 6 groups. In bay other Arthropoda representatives were found: Amphibalanus improvisus (Darwin, 1854) and Harpacticoida. The average biomass of higher crustaceans was 0.454±0.228 g/m2. The main role in its formation is played by Decapoda and is dominated by Diogenes pugilator. The average number of Malacostraca was 280±158 ind./m2. The highest percentage of occurrence and high density of settlement were recorded for Amphipoda. The ranked series by density index was headed by D. pugilator, Echinogammarus foxi, Centraloecetes dellavallei and Echinogammarus karadagiensis. The highest numbers were recorded at stations in the flood zone (0–0.5 m). High abundance and biomass concentrations of Malacostraca were recorded at the stations with sand and pebbles.

The chemical features and the structure of biological communities in the in the three watercourses of Segozero Lake basin. Analysis for the species composition, abundance and biomass of phytoperiphyton, zooplankton, and zoobenthos was carried out. The effect of natural and anthropogenic factors on the formation of the chemical features and structure of lake hydrobiocenoses was analyzed. Variations in the structure of aquatic organism communities are due primarily to specific hydrographic and hydrological characteristics of river stretches. The paper is discussed the main principles of the changes in a structure and functioning of hydrobiont communities in rivers. The trophic status of the rivers, their saprobiological slate, and the significance of individual communities and biotic indices for bioindication of the ecological state of the rivers, are estimated. We concluded that consideration of three groups of organisms enables more comprehensive and reliable monitoring than assessment based on a single group. The abundance and biomass of phytoplankton, phytoperiphyton, zooplankton, and zoobenthos suggest the relatively high degree of their development in lake water, as well as their activity and stability. A peculiarity of the structure of hydrobiocenoses is that they consist of species with appreciably different sizes: from several microns to several centimeters. Therefore, the lists of species dominating in terms of abundance and biomass differ appreciably.

Data on the taxonomic composition of tropical and subtropical lianas in the greenhouse collection of the Botanical Garden of the Ural Branch of the Russian Academy of Sciences are presented. Currently, the collection of lianas includes 136 species (65 varieties and hybrids), 48 genera, 29 families. The largest families are Araceae (60 species) and Vitaceae (13 species), the largest generas are Philodendron (43 species) and Passiflora (9 species). More than half of the species are representatives of the flora of South and Central America (54.8 %). The collection includes endemics of western and southwestern Madagascar; New Zealand; Ecuador and South Brazil. The most numerous biomorphological group is the group of leaning lianas – 63 species. We estimated the success of the introduction and the decorative effect of blooms and leaf of the lianas in the collection. Our results showed about 55 % of species can be assigned to the groups of promising and very promising plants for introduction. The other part of the collection (45 % of species) is unpromising. The main reasons for the decrease in the success of the introduction of these species are the absence of blooms and, accordingly, of germinating seeds. Bloom is observed only in 50 species of lianas in the greenhouse collection. About 20 species had the highest estimates of the decorativeness of bloom (8–9 points). High decorative qualities of non-bloom species are provided by leaves of large size, unusual shape, color or surface texture.

Lung cancer is the most common cancer and the leading cause of cancer mortality worldwide. To date, tissue biopsy has been the gold standard for the diagnosis and the identification of specific molecular mutations, to guide choice of therapy. However, this procedure has several limitations. Liquid biopsy could represent a solution to the intrinsic limits of traditional biopsy. It can detect cancer markers such as circulating tumor DNA or RNA (ctDNA, ctRNA), and circulating tumor cells, in plasma, serum or other biological fluids. This procedure is minimally invasive, reproducible and can be used repeatedly. The main clinical applications of liquid biopsy in non-small cell lung cancer (NSCLC) patients are the early diagnosis, stratification of the risk of relapse, identification of mutations to guide application of targeted therapy and the evaluation of the minimum residual disease. In this review, the current role of liquid biopsy and associated markers in the management of NSCLC patients was analyzed, with emphasis on ctDNA and CTCs, and radiotherapy.
Gastrointestinal disorders as immune-related adverse events

Immune checkpoint inhibitors, such as cytotoxic T-lymphocyte antigen 4 inhibitors, programmed cell death 1 inhibitors and programmed cell death-ligand 1 inhibitors, have recently emerged as novel drugs in the anti-cancer therapy. Their use in different types of advanced cancer has shown good results and an increase in survival rates. However, immune-related adverse events (irAEs) are frequent and often require special care. IrAEs may affect all the organs, but they are most commonly seen in skin, lungs, endocrine glands and in the gastrointestinal tract where small bowel, colon, the liver and/or the pancreas can be involved. Despite being usually mild and self-resolving, irAEs may present in severe and life-threatening forms, causing the withdrawal of anti-cancer therapy. IrAEs, therefore, represent a challenging condition to manage that often requires the cooperation between the oncologists and the gastroenterologists in order to identify and treat them adequately.

Published: April 2021

A discrete linear stability analysis framework for two-dimensional laminar flows is presented. Using two case studies involving analysis of thermal and laminar flows, the stability of flows in the discrete numerical sense is addressed. The two-dimensional base flow for various values of the controlling parameter (Reynolds number for flow past a square cylinder and Rayleigh number for double-glazing problem) is computed numerically by using the lattice Boltzmann method. The governing equations, discretized using the finitedifference method in two-dimensions and are subsequently written in the form of perturbed equations with twodimensional disturbances. These equations are linearized around the base flow and form a set of partial differential equations that govern the evolution of the perturbations. The eigenvalues, stability of the base flow and the points of bifurcations are determined using normal mode analysis. The eigenvalue spectrum predicts that the critical Reynolds number is 52 and the critical Rayleigh number is 6 1.88×10 for the square cylinder and double-glazing problem, respectively, The results are consistent with the previous numerical and experimental observations.
