ОЦІНКА СУЧАСНОГО СТАНУ СИСТЕМИ НЕДЕРЖАВНОГО ПЕНСІЙНОГО ЗАБЕЗПЕЧЕННЯ В УКРАЇНІ

The trends of recent years indicate that the available pay-as-you-go financing pension system soon will not be able to perform its main function – to guarantee monetary benefits to persons who have reached retirement age. This, in turn, generates the need to draw the country’s attention to non-state pension provision. Thus, the article is devoted to the study of the development of the modern status of the system of non-state pension provision in Ukraine and making proposals for its promotion. To conduct the research, the author uses the following tools: statistical analysis – to assess trends in the development of the system of non-state pension provision; graphic method and table method – to visualize research findings on the activities of private pension funds; comparative method – to determine the dynamics in the system of non-state pension provision. In the course of the research, the dynamics of the key indicators that characterize the features of non-state pension provision in Ukraine are considered and analyzed. It is established that recent years are characterized by a lack of positive changes in the territorial distribution of non-state pension funds, lagging progress in increasing the total number of participants of non-state pension provision – in fact, individual entrepreneurs don’t show interest in the system of non-state pension provision. The research emphasizes that the state should pay considerable attention to informing about the non-state pension system to earn the trust and readiness of Ukrainians to collect money in non-state pension funds. In particular, considerable attention should be paid to the creation of open information space for the young generation, which would provide accessible, reliable and understandable data on the activities of private pension funds and the prospects and benefits of joining the non-state pension provision system. It is highlighted that an important aspect in the advancement of the system of non-state pension provision encompasses a positive demographic situation, favorable tax policy both for the employer and the employee, stable financial capacity of the population.

A novel approach to find optimum group replacement period

In the replacement of items that fail suddenly, it is always better to compare the replacement policy adopted whether it is with Pure individual replacement or Group replacement after optimum period. In pure individual policy, failed item is replaced immediately by procuring in the local available market spending the amount at market price. As the usage time increases, the rate of failure increases. In that case, the individual replacement cost always increase proportional to usage period. Replacing the total lot of items as a whole or lot is a better option to consider. In group replacement, lot is replacement at a specified period irrespective of the usage period and condition of the item. As the failure rate in the initial days of the usage period, item replacement cost in the individual replacement case as well as group replacement case is more or less in a narrow price region. We need to take a better decision by comparing Average cost in both the cases. In the present paper, a novel approach is proposed to minimize the number of steps to find the average cost using Table method. The proposed algorithm is programmed in EXCEL. The proposed algorithm can be extended for any number of periods of operation.

Effectiveness of Ethanolic Extract of Aloe Vera Leaves against Staphylococcus aureus

Since long ago Indonesia used nutritious plants as traditional medicines. Various types of plants in Indonesia can be used as alternative ingredients, one of which is aloe vera. Aloe vera contains saponin and anthraquinone, so aloe vera leaves function as antiseptic and antibacteria. Staphylococcus aureus is a gram-positive coccus bacteria. This bacterium is often found as a normal germ flora in humans. Staphylococcus aureus can cause infections in humans and animals. This study aims to determine the effect of ethanolic extract of Aloe vera leaves in inhibiting Staphylococcus aureus by using maceration extract method. The concentrations used were 20%, 40%, 60%, 80% and 100% with positive control (Erytromycin) and negative control (aquades). The inhibitory zone analysis is done using the table method. Test of ethanol extract of Aloe vera leaves in inhibiting Staphylococcus aureus produced inhibition zones at concentrations of 60%, 80% and 100% with average diameter of 6.94 mm, 6.22 mm and 9.5 mm. The conclusion of this research is the ethanolic extract of Aloe vera leaves can inhibit Staphylococcus aureus in high concentrations

ABSTRACT SAS4A is presently the worldwide standard computer code for simulation of the initiating phase of the Core Disruptive Accident (CDA) in MOX-fueled Sodium-cooled Fast Reactors (SFR). In order to improve the capability of the computational code, SAS4A, to be applied to the safety assessment for SFRs, detailed investigations of physical phenomena under unprotected loss-of-flow (ULOF) conditions were conducted, and physical models to be developed and improved were identified using the Phenomena Identification and Ranking Table (PIRT) method. A fuel stub motion, in which the residual fuel pellets would move to the core central region after fuel pin disruption, was selected as one of the key phenomena to be simulated properly and a key concept of the fuel stub motion model was presented.

Operation algorithms and application of functional converters modulating voltage for generation of precision radio signals with angular modulation

The article presents a synthesis of algorithms and structures of functional converters modulating voltage for their use as part of quadrature radio signal generators with angular modulation. The study is an alternative method for suppressing spurious amplitude modulation and spurious phase modulation, using controlled spectrum expansion using functional converters modulating voltage. The main requirement for functional converters is the accuracy of representation of the modulating voltage in nonlinear converters by a limited number of terms of Taylor series decompositions that depend on the implemented modulation index. Functional conversion accuracy analysis, spectral analysis and technical implementation of functional converters by table method on the basis of analogue-to-digital converter, permanent memory device and digital-to-analog converter in mode of generation of phase modulation index equal to π are performed.

Detection and Identification of Power Switch Failures Using Discrete Fourier Transform for DC–DC Flying Capacitor Buck Converters

Prompt detection of power switch failure is crucial for fault-tolerant operation of multilevel converters. This article presents a new technique of detecting, identifying, and locating a device fault in a multilevel dc-dc flying capacitor (FC) buck converter (FCBC). This is realized by continuously analyzing the magnetic component (inductor or transformer) voltage harmonics for failure detection and subsequently identifying failure type and location with a look up table method. The harmonics analysis is performed by the existing FPGA controller using discrete Fourier transform (DFT). This new approach uses an auxiliary winding in the existing inductor core without adding any new hardware and can identify the location and fault type with good accuracy and speed. The experimental results validate the proposed concept on a three-level GaN-based FCBC prototype.

As the Republic of Moldova has limited opportunities to provide generous financial support to farmers, it is extremely important to efficiently use subsidy means, so as to contribute to the development and modernization of agriculture and rural areas. The development of agriculture in a dynamic way can be achieved on the basis of an efficient subsidy system, administered, monitored and evaluated. The aim of the research is to analyse and evaluate the efficiency and impact of subsidization on the development of the agricultural sector and to ensure a stable increase in agricultural production, emphasizing main support measures in this direction. To carry out this study, various research methods were used, such as: observation method, table method, analysis and synthesis method, comparison method, monographic method, statistical data collection. This article presents an analysis of the evolution of the subsidy fund for agricultural producers, which has increased 2.25 times in the last 7 years. There has also been analysed the structure of beneficiaries of subsidies according to the legal organizational form, who received subsidies during the reference period. It has been found that households are in the top of beneficiaries of subsidies who had a share of 62.03% in 2018. The distribution of subsidies by development regions and per one hectare of agricultural land in the profile of development regions has been studied and it has been found that the predominant share is held by agricultural enterprises in the Centre region, about 38.9% of the means of the subsidy fund. The results of the research show an increase in the subsidy level, through support measures. In this context, we can mention that the support measures must ensure an efficient use of the subsidies

Design and improvement of the pruning algorithm of the Chinese chess in the computer games

Computer games have always been considered to be the most challenging task in the field of artificial intelligence specially the Chinese chess as an example. The core technology of the computer games is the search. This work is studied to research an improved pruning strategy in order to achieve a deeper level search of the game tree in a limited time. On the basis of the traditional alpha–beta search algorithm, the worthless nodes are discarded to be never searched by introducing the deep iterative, history table and other auxiliary methods of pruning. The number of nodes searched is effectively reduced to make the pruning earlier to shorten the search time. At the same time, its search depth is higher than the original search algorithm. The advanced and modified algorithm is proved to be practical and applicative by experimentations and tests of computer games system provided in this study.

Design of Magnetic Shield for Hall-Effect Current Sensor Using Integrated Magnetic Concentrator

This paper proposes a shield shape design for minimizing the integrated magnetic concentrator (IMC) hall current sensor shield. Inside flux density and outside magnetic field error rate aren’t satisfied with performance by reducing an initial U-shaped IMC hall current sensor shield’s width and height for an IMC hall current sensor minimization. In order to solve the problem, first, inside flux density is decreased by adding air gap in the shield. Second, outside magnetic field error rate is decreased by adding top shield. Finally, suitable shield shape for minimization is designed by adding top middle shield. The minimization design work is reduced the number of experiments by using the orthogonal array table and main effect analysis method, which are one of the methods of the experimental design method. The proposed model satisfied the design considerations, and the shield area is reduced by 83.7% from the initial model, proving that it was a suitable shield shape for minimization.
