TOURISM AND TOURIST INSURANCE SYSTEMS
Authors:   Lviv Polytechnic National University, Rymar Yurii
Published: June 2022

The modern insurance market offers a wide range of insurance products, thanks to which it has the opportunity to integrate with other sectors of the economy. Tourist activity by its economic nature is characterized by a high degree of risk, and therefore its effective functioning is impossible without insurance. All developed countries have long introduced insurance in the tourism market for the successful functioning of the industry and the state economy as a whole. The issue of insurance in tourism in the Ukrainian market is problematic, as it is characterized by low awareness and trust of the population, insufficient attention from government agencies. However, the coronavirus pandemic has made significant adjustments to the dynamics of the insurance market in 2020. The sharpest economic downturn since the 1930s has led to a drop in demand for insurance in 2020, especially for life insurance services. Nevertheless, the insurance industry is showing resilience in the pandemic and intends to overcome the deepest global economic recession in history, and predicts a slight recovery of insurance markets in the next 2 years. Therefore, the study and analysis of the dynamics of the insurance market in the conditions of the world in 2020, are particularly relevant. That is why the theoretical justification for the development of insurance systems in tourism is always timely. In the article the author described the main forms and types of insurance in tourism - the system of insurance of foreign economic relations in tourism ("Assistance"), personal (life and pension insurance, pension insurance, accident insurance, health insurance), property (property insurance from fire risks and natural disasters (fire insurance), insurance of crops against natural disasters, drought, hail, etc., insurance of animals in case of death due to disease and accidents, insurance of vehicles against accidents, theft and other risks, etc.), environmental insurance, liability insurance.

The article considers the development of e-government in Ukraine during the military aggression in our country and under the influence of such a disease as COVID-19, because due to the mass pandemic many institutions that provide necessary administrative and public services to citizens were forced to go online regime, which was a great impetus for the spread of digitalization and modernization of legislation, and due to the imposition of martial law, the provision of some administrative services was suspended and access to registers was limited, so the question arises to study this issue. We have studied the legal framework for the development of e-government in Ukraine. The essence, features and advantages of functioning of e-government technologies are also analyzed. The current state of e-government in Ukraine in the period from 2016 to the present is determined separately, namely the compliance of Ukrainian legislation with the objectives of e-government development. Consideration in the work of the policy, goals and objectives of the newly created body in this area, namely the Ministry of Digital Transformation of Ukraine, is relevant. We also considered the policy of the newly formed government regarding the introduction of "State in a smartphone" through the use of such a mobile application as "Action", which has recently become very popular due to the simplified mechanism of providing administrative services to citizens without leaving home. Through the prism of European experience, the introduction of such an application as "Action at home", which facilitates the control of people who are already ill or in self-isolation. The issue of obtaining a certificate of internally displaced person status was considered separately, which is very important for people who have been forced to leave their homes and need protection from the state. Our research shows that even the impact of emergencies can lead to positive developments in the country, and after reading this paper you will understand that the government's plans to develop e-government are quite ambitious, but at the same time promising. Therefore, in the near future, most public services will be available using only a smartphone or computer, and due to hostilities, some services have been restricted but are temporary and in constant motion.

Published: June 2022

The article is devoted to theoretical and practical issues of professional selection. The authors draw attention to the forced need for Ukraine to repel military aggression from the Russian Federation. All the forces of society and the economy of the country are aimed at fighting the aggressor, and at the same time, every scientist in his workplace should contribute to the development of scientific research that will help strengthen the security and defense forces of our country. One of the directions for the formation of highly professional special units of the security and defense forces is the introduction and improvement of scientifically based stages of the professional selection of candidates for service in the relevant units of the Armed Forces, NGU, SSU, FIS of Ukraine and other components of the armed forces. security and defense forces. It is proved that the theory and practice of professional selection, methods and forms of its organization are based on the advanced achievements of modern science. In particular, legal, general and social psychology, psychophysiology, ergonomics, engineering psychology, psychodiagnostics, neuropsychology, psychiatry, physiology of higher nervous activity, psychocorrection and psychotherapy. All modern achievements of human science and its relationship with technical means, systems, modern weapons and the environment in the process of official activity can be used for professional selection. Taking into account the physical and mental characteristics and abilities of a person to act in extreme situations is the main issue in the professional selection of candidates for service in special units of the security and defense forces. The article notes that the First and Second World Wars served as a powerful stimulus for the development and implementation of professional psychological selection. For many types of military professions, professiograms and psychograms have been compiled that describe the professionally important qualities that actors should possess. In a difficult situation of military aggression from the Russian Federation, domestic military psychologists hone their skills in extreme conditions, apply psychological tests and professional methods in conditions of scarcity, find and develop new approaches to the process of professional selection. The authors come to the conclusion that it is necessary to further study the existing methods and techniques of professional selection, which have proven themselves especially well at the present stage. Psychologists of the security and defense forces gain invaluable practical experience in the field of professional selection. This practical experience should be studied, systematized, generalized and found a scientific basis for further use.
JUDICIAL PRECEDENT AS A SOURCE OF LAW IN THE ANGLO-AMERICAN LEGAL SYSTEM
Authors:   Yaroslav Mudryi National Law University, Madina Viktoriia , Mitko Mykhailo ,   Yaroslav Mudryi National Law University
Published: June 2022

The article deals with the issue of the features of the system of sources of law in various legal systems, which were formed in accordance with local traditions, taking into account external influences. One of the main problems considered in this article is the determination of the place of judicial precedent in the Anglo-American legal system, its significance in solving a particular case. This study raises the issue of the history of the emergence, development of judicial precedent as a legal phenomenon, its constituent elements and their role as an auxiliary element in the creation of the rule of law by the court and law enforcement, regardless of the level of the judiciary in the countries of the Anglo-American legal system. Unlike the system of sources of law in the continental legal system, where the main source of law is a law or a codified legal act, in the Anglo-American legal system, it is judicial precedent that is the main source of law, as a manifestation of common law. Historically, due to the large number of cases that needed to be decided first by non-professional judges, and then by qualified lawyers and the underdevelopment of the legal framework, such persons had to carry out an extensive interpretation of legal norms and sometimes create new ones with their own hands, interpreting them each time. So, after a certain period of time, the lawyers unified the decision of the judges, such collections became important when the court could refer to an already decided plot with the same factual circumstances and apply the “ratio decidendi” in a new case. After such a rapid development of judicial law in the Anglo-American legal system, it became quite clear that not only the highest courts can create a judicial precedent by their decision, but other courts of the general system have the right to do so: as courts of first instance (district courts), as well as appellate courts and, for example, the US Supreme Court. This raises the question of the legal force of such precedents, depending on the level of the court that created it. Therefore, this question is the next one, which is considered in this article. An important factor is the use of the comparative method of studying the above issues, and therefore a rather interesting point in the analysis of information is the comparison of the essence of judicial precedent in the continental legal system and the Anglo-American legal system.

The author notes that during the war there were a number of problems: shortage of drinking water, wastewater discharge and significant environmental pollution. It is noted that in such conditions not enough attention is paid to environmental regulation. Accordingly, the procedure for assessing the impact on the environment throughout Ukraine for the period of martial law or hostilities has been suspended, while the number of environmental problems is growing exponentially. Emphasis is placed on the importance of conducting strategic environmental assessment, which will be especially important in the construction of new infrastructure facilities. The author emphasizes that countries and organizations that provide significant financial assistance to Ukraine will provide access to finance only if they declare and fulfill their European integration aspirations and commitments. It is noted that the European Commission has expressed a personal desire to provide assistance in monitoring the environment and environmental consequences of war based on satellite data from the Copernicus system. In the face of significant destruction and the need to build large numbers of housing for Ukrainians, Ukraine has committed itself to implementing Directive 2010/31 / EU on the energy performance of buildings into national law. The need for decarbonisation of cities through the implementation of the EU-Covenant of Mayors initiative was emphasized. The readiness to support Ukraine's accession to LIFE, which will contribute to effective assistance in environmental protection and accelerated transition to a clean, energy-efficient, low-carbon and climate-resilient economy, is noted. The emphasis is placed on the environmental issues of the Danube region and regulatory ways to solve it and minimize the negative consequences. European legal instruments that need to be ratified in the framework of environmental security and reducing the vulnerability of Ukrainian communities to climate change are considered.

Химические технологии в сверхкритических состояниях (с использованием сверхкритических флюидов) находят все большее применение и позволяют полностью отказаться от катализаторов, изменяющих скорость химических реакций, и обеспечить аномально высокую растворяющую способность вступающих в реакцию веществ. Переэтерификация растительных масел при получении эфиров жирных кислот без применения катализатора осуществляется при значениях температуры и давления, превышающих критические параметры реагирующих жидкостей, обладающих одновременно свойствами газа и жидкости со значительно низкой вязкостью, высокой теплопроводностью и проникающей способностью, что способствует интенсивному тепломассообмену и ускоряет термохимические процессы. Для этих условий предложен алгоритм управления технологией получения биодизельного топлива, как системы тепловых и тепломассообменных процессов с использованием пароэжекторного теплового насоса (ПЭТН). Повышена точность и надежность управления, созданы реальные перспективы в повышении качества биодизельного топлива, что связано со стабилизацией температурных режимов тепловых процессов в условиях случайных возмущений как со стороны возможного изменения состава растительного масла, обусловленного его качеством, так и со стороны возможных технологических сбоев в работе основного и вспомогательного оборудования.

Chemical technologies in supercritical states (using supercritical fluids) are increasingly used and make it possible to completely abandon catalysts that change the rate of chemical reactions and provide an abnormally high dissolving ability of the reacting substances. The transesterification of vegetable oils in the production of fatty acid esters without the use of a catalyst is carried out at temperature and pressure values exceeding the critical parameters of the reacting liquids, which simultaneously have the properties of gas and liquid with a significantly low viscosity, high thermal conductivity and permeability, which contributes to intensive heat and mass exchange and accelerates thermochemical processes. For these conditions, an algorithm is proposed to control the technology of obtaining of also-diesel fuel, as a system of thermal and heat-mass exchange processes using a steam ejector heat pump. The accuracy and reliability of control has been improved, real prospects have been created in improving the quality of bio-diesel fuel, which is associated with the stabilization of temperature modes of thermal processes in conditions of accidental disturbances both from the side of a possible change in the composition of vegetable oil due to its quality, and from possible technological failures in the operation of the main and auxiliary equipment.

Leakage Control using Geomembrane Liners
Authors: Giroud Jean P.
Published: June 2022

Geomembrane liners are used in all types of containment structures. Evaluating the performance of a geomembrane liner is a challenge. While zero leakage into the ground is a legitimate goal if the leaking liquid may pollute the ground and the ground water, or if the soil integrity can be impaired, zero is unrealistic and impossible to measure. Furthermore, zero leakage is not an appropriate goal in some applications such as geomembrane-lined dams. In this paper, it is shown that the difference between acceptable and unacceptable leakage should result from a rational analysis of the potentially detrimental consequences of leakage. Also, it is shown that the specified leakage must be achievable and measurable. Therefore, emphasis is placed on the quantitative evaluation of leakage. Practical guidance is provided for leakage reduction at construction stage and design stage; and typical leakage rates are mentioned. Potential failures associated with leakage control measures are described. Case histories illustrate both failures in case of misuse of geomembranes and the durability of geomembranes. This paper is intended to contribute to the appropriate design and the safety of geomembrane-lined structures.

Authors: Velten Rodrigo Z. , Lima Dario C. , Fontes Maurício P.F. , Carvalho Carlos A.B.
Published: June 2022

t. This paper addresses the influence of electric potential difference on the electroosmotic decontamination of two tropical soils from Brazil. The laboratory testing program encompassed: (i) two residual soils of gneiss, a C-horizon saprolite clayey silty sand (soil sample A) and a B-horizon sandy silty clay (soil sample B); (ii) mineralogical and chemical analysis of the soils; (iii) addition of an aqueous solution of cadmium nitrate in the concentration of 100 mg.L-1 to the soil samples; (iv) compaction of the mixtures specimens at the Standard AASHTO; (v) electroosmotic decontamination tests applying 5, 15 and 30 V; (vi) application of a modified sequential extraction analysis adapted to tropical soils. The results support that the PZC of soils influenced the direction of cadmium migration and that the increase in the applied electric potential difference led to the increase in the amount of extractable contaminant.
Use of Parallel-Seismic and Induction-Logging Tests for Foundation Depth Evaluation Under Difficult Conditions, a Root-Pile Foundation Embedded in Rock
Authors: Souza Tiago J. , Hemsi Paulo S. , Gandolfo Otávio C.B. , Aoki Paulo C. , Ribeiro Alex F.
Published: June 2022

A case study on the application of the parallel-seismic (PS) and induction-logging (IL) tests combined to evaluate the depth of a 25-cm diameter root-pile belonging to the foundations of a telecommunication tower located in Santana de Parnaíba, São Paulo, Brazil, is presented. The foundation element is embedded in a friable and altered meta-sandstone rock. The relatively small diameter of the pile and the presence of rock as surrounding material tend to limit the interpretation of the PS test. Nevertheless, the technique applied in this study showed satisfactory results. On the other hand, the existence of electromagnetic interference from the antenna itself limited the interpretation of the IL test in this case. The estimated depth of the foundation element was evaluated from the PS test as ranging from 6.5 to 7.5 m, which was later verified to be in agreement with the pile as-built documentation. When the possibility to drill boreholes at a site under investigation exists, the methods presented in this paper may become good options for the determination of the unknown depth of foundation elements in altered rock
Shear Strength and Stiffness Degradation of Geomaterials in Cyclic Loading
Authors: Pytlik Robert , Baars Stefan V.
Published: June 2022

Cyclic loading on civil structures can lead to a reduction of strength and stiffness in the loaded materials. The life span of many cyclically loaded structures such as wind turbines, high-speed train tracks and bridges strongly depends on the foundation. The soils and rocks in the foundation can be subjected to cyclic loads from natural and human sources. In order to evaluate the fatigue behaviour of geomaterials, this paper presents static and cyclic triaxial test results for several geomaterials. It was concluded that cyclic loading on different geomaterials can cause different types of effects. The shear strength of cohesionless crumbled limestone increases during cyclic loading; while for cohesive materials, such as gypsum and mortar, the strength decreases. The strength decrease can be seen as a degradation of the cohesion. The most significant factor in the cohesion reduction was found to be the number of applied cycles. It was also noticed that the friction angle for sands does not reduce under cyclic loading. A fatigue limit was not found for cohesive geomaterials; neither a dependence of the strength reduction on the cyclic loading ratios.
Determining the Elastic Deformation Modulus From a Compacted Earth Embankment Via Laboratory and Ménard Pressuremeter Tests
Authors: Angelim Renato R. , Cunha Renato P. , Sales Maurício M.
Published: June 2022

Compacted earth embankments are routinely used in dams and many others infrastructure projects in Brazil. It is common to use fine-grained soils for these embankments, which are placed and compacted in the field at specific values of unit weight and water content. Their design is usually performed using geotechnical parameters from laboratory tests on compacted samples, although in situ tests could emerge as an alternative for determining specific parameters, as such tests can be conducted reasonably rapidly and can somewhat account for local inherent conditions of the soil such as confining stress levels, water content and mineralogical variations. Therefore, this paper explores the application of Ménard-type pressuremeter tests to determine the Young’s modulus of compacted soil layers from the side flank of a large-scale earth embankment constructed in the city of Goiânia in the Midwest Region of Brazil. The embankment was compacted under controlled conditions, permitting the extraction of undisturbed soil blocks at distinct levels during its erection. Laboratory tests, such as consolidated isotropic triaxial and oedometer tests, were performed on samples at their natural water content. Young’s moduli were derived from these laboratory tests and compared with the elastic moduli measured using the pressuremeter, either directly under different (external) conditions or at normalized levels of the effective confining octahedral stress. This comparison of results enabled the establishment of preliminary statistical correlations between the average (in situ and laboratory) moduli, which will be useful when using the Ménard pressuremeter for a preliminary design or a post-construction check of compacted earth embankments.
Study of the Shear Strength of a Tropical Soil with Grass Roots
Authors: Neto Manoel I.M. , Mahler Claudio F.
Published: June 2022

The role of roots in shear strength has been a matter of research and also uncertainties. An investigation was conducted to identify and quantify the contribution of the roots of vetiver grass (Chrysopogon zizanioides) to the shear strength of soils, by means of triaxial testing. Samples were prepared from 4-inch PVC pipe molds, where tropical soil was compacted and specimens of vetiver seedlings, obtained by tillering, were grown. After 24 months of growth, from each mold of the mature vetiver grass it was possible to get at least four samples with roots inside. Similar samples of the same soil without vetiver grass were submitted to triaxial tests to determine shear strength of soil alone. Confining pressure ranging from 25 to 200 kPa was used in triaxial extension drained tests to determine a Mohr-Coulomb envelope. The shear strength parameters of soil without roots, cohesion intercept and friction angle were respectively 13 kPa and 34°, and the Mohr-Coulomb envelope of the soil with vetiver roots showed a bilinear shape with cohesion and friction angle, respectively, of 17 kPa and 59° for confining pressure below 75 kPa and 22 kPa and 33° for confining pressure above 75 kPa. So an increase in shear strength was obtained, because the roots acted to reinforce the soil mass. Triaxial compression tests were conducted in the same soil with and without roots and no significant increase in resistance was observed. The result was observed due to a vertical spread of roots, since any reinforcement in the same direction of the compressive force does not contribute to increase the strength. In conclusion, for extensional stress above 75 kPa confining pressure, the friction angle was the same as that of the soil without roots, although the intercept of cohesion was larger. Below 75 kPa, the soil showed a very large apparent friction angle due to the roots. Therefore, vetiver roots increase the shear strength in soils under extensional loadings.

In this study, fifty driven piles located in the Santos Coastal Plain (“Baixada Santista”), Brazil, have been dynamically tested at various times after installation, indicating gain of capacity over time. The average side shear resistance, related to a low-OCR clayey layer – known as SFL soil , was evaluated over time, indicating side shear set-up within a relatively narrow range of values (between 2.0 and 2.5) approximately 20 days after installation. The cavity expansion theory, which considers an ideal cohesive soil, has been used to predict the effective radial stress over time, considering two main parameters: undrained shear strength and horizontal coefficient of consolidation. Finally, the average of measured pile shaft capacities were compared to the unit shear resistances predicted by the Method (effective stress method). The theoretical values of side shear set-up are fairly similar to the results of the analyzed load tests, which seems to support the viability of the presented method.

Coronavirus 2019 (COVID-19) disease patients present with upper respiratory symptoms; however, these patients may show gastrointestinal symptoms on arrival at the hospital. This finding requires an abdominal physical examination and imaging for 33% of patients. Enteroatmospheric fistulas (EAF) may form a connection between the external environment and the gastrointestinal tract and usually presents various difficulties in controlling the disease without surgical intervention. Its management requires a high level of clinical expertise to control and treat the fistula. In this case report, spontaneous EAF and its management are presented in a 65-year-old morbidly obese female patient who spontaneously had EAF during her hospitalization for COVID-19.

The information and the data of the bridge approach condition is important because it allows designers to know the response of the soil once loaded with vehicles and respectable suggestion for correct engineering solutions to beat the matter. There are a few clarifications the reason of problem occurred at bridge approach was recently inspected by other researchers previously and one of the issues is a dissimilarity between the height of the bridge and road on the connection. The objective of this research is characterize and create techniques for field investigation to inspect the effect of vibration from vehicle loading at bridge approaches and this case might be referred to as a repetitive cyclic loading. The aim of this research is to investigate critical location of vibration at bridge approach model by the influence and effect from measurement tools. This research concentrated on constructed field model of the unpaved bridge approach model in Research Centre for Soft Soil Malaysia (RECESS), Universiti Tun Hussein Onn Malaysia (UTHM), Johor, Malaysia. A portable measurement equipment system with high sensitivity triaxial ICP accelerometer used to investigate and measure the effect of vibration loading at unpaved bridge approach field model. Piezoelectric (ICP) accelerometer is now preferable for researchers for the field surveillance or laboratory testing. From the analysis, it can be stated here that the vibration value increases as the speed and vibration level produced changes from L1 to L2. In the transverse direction, it is found that P1 values are larger than P2 to P6 values at both sites BAA and BAB. On the longitudinal direction, the farther away the plate compactor is from the bridge model connection, its value decreases and it is found that the D1 area has a higher vibration value compared to D2 to D5. It may be then, concluded that in this research it is similar to the previous research at the actual study site where the vibration value is high in the area 1m to 2m from the bridge connection.

The Building of  Simple Rent House Tower A was designed in Nagrak Flats, Cilincing, North Jakarta with an exixting area of 812,5 m2 with a total of 16 floors, which was redesigned with land data for area of Gunung Anyar, Surabaya, with an area of 578,5 m2 with a total of 11 floors. From the Standard Penetration Test (SPT) data, it was found that the Flat Building was built on soft ground conditions (SE Site Class), with risk category II and including Seismic Design Category D. The calculation of the flat building structure uses a dual system structure, namely with special moment-bearing frame system and shearwall which refers to SNI 03-1726-2012 (Badan Standarisasi Nasional, 2012) and SNI 1726-2019 (Kementrian Pekerjaan Umum, 2020a) : Earthquake Resistance Planning Procedures for Building and  Non Building Structures. Earthquake load planning for the design of the flats building uses dynamic response analysis. Non-earthquake loading refers to SNI 03-1727-2013 (Kementrian Pekerjaan Umum, 2013a)  and SNI 1727-2018 (Badan Standarisasi Nasional, 2020): Minimum Design Load and Related Criteria for Buildings and Other Structures. Secondary structure of the flats building, namely the floor and roof plate and stairs, while the primary structure includes beam, column, and beam-column joint that support the secondary structure. Shear wall is used to resist shifting of buildings when an earthquake accurs. The lower structure consists of the pile foundation, pilecap, tie beam. The flats building structure is a reinforced concrete structure which calculations refer to SNI 03-2847-2013 (Kementrian Pekerjaan Umum, 2013b) and SNI 2847-2019 (Kementrian Pekerjaan Umum, 2020b) : Requirement for Structural Concrete for Buildings and Explanations. Calculation of the structure of the flats building uses SAP2000 and the result of this calculation are in the form of engineering drawings consisting of architectural drawings and structural drawings presented using AUTOCAD.
The Effect of Sawdust as Substitution of Fine Aggregate on Compressive Strength of Concrete

Published: June 2022

The need for concrete is growing as the construction industry grows around the world. This is a problem for the environment because almost all the materials used to make concrete come from excavated mines. The use of waste materials as a substitute for aggregates can be a solution to reduce the impact of environmental damage. This study used sawdust as a substitute for fine aggregate. The sawdust was partially pretreated using 20% lime-water to reduce the levels of lignin and hemicellulose in the sawdust. The study was conducted to determine the effect of the use of sawdust, with or without pretreatment, on the compressive strength of concrete and the workability value based on the slump value of the concrete at 0%, 5%, 10%, and 15% substitution variations. The slump value of concrete decreases as the percentage of fine aggregate substitution increases. The compressive strength of concrete at the age of 28 concrete decreases with the increase in the percentage of fine aggregate substitution. Concrete that fine aggregate was substituted using pretreated sawdust had better slump and compressive strength values at 28 days of age than concrete that fine aggregate was substituted using non-pretreated sawdust.

One of the important components of the sea transportation system for an archipelagic country like Indonesia is the port. The port acts as a node for sea and land transportation modes in supporting and driving the economy, and serves as a gateway for trading commodities in an area as well as a place for loading and unloading goods, embarkation and debarkation for ship passengers. The method used is the method of detailed analysis. This method uses data from each productivity of each job, so that the coefficients from the analysis of the unit price of the work can be obtained, with the ultimate goal of knowing the costs of each method, both Cast In Situ and Precast methods. The results of the analysis show that the slab using the Cast In Situ system is more efficient than the Precast slab. The total implementation cost for the Cast In Situ slab is Rp. 5,648,170,- and for the Precast slab it costs Rp. 6,794,480, - with a cost deviation of Rp. 1.146.310, - or the difference in percentage 9.21%.
