SCIENTIFIC APPROACHES TO THE DEFINITION OF THE TERM "CRITICAL INFRASTRUCTURE"
Authors:   Bila Tserkva Institute of Continuing Professional Education of the University of Education Management, Uriadnikova Inga , Zaplatynskyi Vasyl ,   Technical University «Metinvest Polytechnic»
Published: February 2021

Purpose: scientific substantiation of the concept of “critical infrastructure” based on research of definitions of “infrastructure” and “critical” and comparison of definitions that are widely used in different countries. Methodology: analysis of the content of the concept of “critical infrastructure”, based on the content of the basic terms “infrastructure” and “critical”, analysis of the concept of “critical infrastructure” in laws and regulations of different countries and logical-determinative assessment of these concepts. Results: the general concept of “critical infrastructure” is substantiated – physical and virtual systems, objects and resources – the destruction, destruction or reduction of capacity of which will lead to significant threats to the country (region or city), its national security, life and health. A common understanding of this concept is important in the context of growing and diversifying threats and increasing the complexity of technical, information and social systems, when there is a growing need to protect the basic, ie critical parts of these systems, without which they can not function. Based on the analysis of existing concepts used in regulations and legislation of different countries, as well as scientific approaches of different authors, the main logical characteristics of this concept are identified, and based on the synthesis formed a generalized concept of “critical infrastructure”, which can be the basis for formulating derivatives such as social critical infrastructure, critical engineering infrastructure, etc. Scientific novelty: On the basis of numerical modeling the regularities of stress distribution in rocks under detached rock packs of different shapes have been investigated, which allowed substantiating the parameters of the last and compensatory voids between them to ensure the stability of workings in the soft soil rocks. Scientific novelty: on the basis of comparative analysis the characteristic features of the concept of “critical infrastructure” are singled out, a variable number of definitions of “critical” and “infrastructure” is analyzed, and a general definition of this concept is proposed, which provides a common understanding and can be used. Practical significance: the formulated definition of the concept of “critical infrastructure” will allow the unification of this concept in the scientific field, legislation and regulations. It will allow to formulate derivatives of this concept, in particular, transport, military, social, engineering infrastructure on uniform methodological approaches.

Authors: Saleh M Nurul Ikhsan , Sari Ratna , Alim Puji
Published: February 2021

The spread of the Coronavirus disease (COVID-19) pandemic in many countries around the world has changed the learning-teaching process in higher education sectors from face-to-face learning to online learning. This study aims to understand undergraduate students’ views on the implementation of online learning during the COVID-19 pandemic. This research was conducted on 4th to 8th-semester students at the Islamic higher education, Universitas Islam Indonesia, using a qualitative case study. Findings of the study have consisted of three broad themes; firstly, the advantages of online learning: increasing technological literacy, flexibility in learning, improving self-ability, being financially efficient, and supported various learning media; secondly, the weaknesses of online learning: heavy tasks, less effective and decreased enthusiasm, little control from the lecturers, and technical problems; thirdly, constructive feedback on the implementation of online learning: the creation of interesting learning videos, fun learning strategies, holding quizzes, notification of lectures to be multiplied, free internet quota, and additional time for working on assignments. The findings reinforce other studies where the implementation of online learning still requires improvements, particularly during the COVID-19 pandemic. This research can be a reference in policymaking. Further research is needed from the perspectives of lecturers and policymakers to complement the findings.
Islamic Primary Schools in The Netherlands: The Founding, The Debate, and The Outcomes
Authors: Driessen Geert
Published: February 2021

At present around 865.000 Muslims live in the Netherlands. In 1988 the first Islamic primary school was founded; now there are 61 with 15,000 students. Islamic education always has been a highly controversial topic in the Netherlands. The debate centers around the question whether the schools contribute to the integration of Muslim youth into Dutch society, or leads to isolation and segregation. This article’s goal is to entangle why and how the schools were established, the obstacles met in this process and the resulting heated societal debate, and the schools’ attainments in terms of cognitive and noncognitive student achievement. To arrive at these insights a review and analysis of the literature was conducted. The results show that Islamic schools academically achieve relatively well, that is, taking into account their largely socioeconomically disadvantaged student population. Also, they perform best on a pen-and-paper integration test. This does not mean, however, that especially populist and right-wing politicians are convinced now that all Muslim youngsters will accept the Dutch norms and values and will integrate into Dutch society.

Authors: Daniyal Muhammad , Khan Mrestyal
Published: February 2021

Banking is one of the fastest-growing sectors because of its contribution to the economy, however, today employee retention is demurring for banks and they are striving to fulfil this challenge. It has been observed from the past few years that it is due to the lack of knowledge related to the proper implementation of HR practices in the commercial banks. The main purpose behind conducting the research is to understand the effect of compensation (C), working environment (WE), training and development (T&D), and performance appraisal (PA) on employee retention (ER). The study used convenience sampling with a sample size of 200 and data was collected from the employees of different commercial banks located in Islamabad and Rawalpindi. The empirical results showed that WE, PA, and COM have a significant positive relationship with the ER whereas T&A has the insignificant one.
MODELING AND CALCULATION OF THE PHOTOLUMINESCENCE SPECTRUM OF A HETEROSTRUCTURE WITH A QUANTUM WELL BY THE EXAMPLE OF ALGaAS / GaAS
Authors: Давыдова З.
Published: February 2021

This research aims to improve the available means for characterizing the emission properties of quantum well heterostructures by modeling and calculating the absorption and photoluminescence spectra using the GaAs/AlGaAs heterostructure as an example. Research is conducted based on multilayer heterostructures and heterostructures with quantum wells to develop detectors and emitting elements in the infrared frequency range, pulsed solid-state generators in the millimeter and submillimeter-wave ranges. The study of radiating properties of heterostructures with a quantum well on A3B5 compounds has become widespread [1-3]. It is possible to control the heterostructure's emission frequency by selecting the optimal composition of the wideband semiconductor layer, the level and type of its doping, the doping region, and the quantum well layer width, which is of applied importance for the development of optoelectronic devices. Technologies for manufacturing such heterostructures are labor-intensive, time-consuming, and expensive processes, which contribute to developing methods for modeling and calculating the characteristic frequencies of radiation and absorption of radiation. Based on such calculations, radiating elements of the submicronic wavelength range can be developed based on heterostructures with a quantum well on the A3B5 type compounds. [4]
HISTORY AS A PROBLEM
Authors:   Institute of oriental studies, Russian academy of science (MOSCOW), Alaev Leonid B.
Published: February 2021

This paper continues the discussion started with the review by a group of colleagues from the Southern Federal University [Volchik, Lyubsky, Makarenko, Petrov, 2019] of Leonid B. Alaev’s monograph “Issues of the History of the Orient” [Alaev, 2019] and presents author’s commentary to the review of said book by another group of teachers from the same University [Drach, Kirillov, 2020]. G. V. Drach and A. A. Kirillov doubt many author’s statements, and first of all, the critical estimation of the contemporary condition of theoretical approaches to the study of history, particularly — the degree of obsoleteness of Marxian methodology. The authors of the review do not take into consideration the fact, that recent research undermine the so- called formation theory, and propose nothing in its stead. Attempts to use other approaches (for instance, civilizational) to the World history, have produced no significant results. Meanwhile, the search for a “golden key”, for a factor capable to explain everything, proceeds. In Russian situation such a “golden key” is most often seen in an economic factor and belittling the importance of spirituality, the status of morality and formation of personality. There are no doubts, that economic relations play great role in social life, that economic indexes are very important in studying any society, but one should admit that the economic situation does not determine everything, for instance, cultural conditions, political structure and so on. The degree of hostility towards ‘bourgeois’ scholars, as compared to the Soviet times, decreased significantly, but did not vanish completely, being transmuted from ideological into geopolitical opposition. It is an obstacle on the way to candid discussion. It is necessary to separate problems, which can be discussed on the basis of common principles of strive for truth, from the views, determined by political and ideological positions of scholars, which are not disputable because the same terms and events are understood differently.

Authors: Akram Muzammila , Ullah Hafeez , Akhter Nasreen
Published: February 2021

The present study was conducted to diagnose alternative frameworks and to explore its best possible reasons in English speaking of prospective teachers. The present study was a case study. Diagnostic oral test and interviews were used as research tools. The three hundred (300) prospective teachers of B.Ed. (1.5 years) and BS (Hons) classes were selected purposively as a sample for an oral diagnostic test. The fifteen (15) prospective teachers who possessed more alternative frameworks were selected purposively for a semi-structured interview. Data were analyzed qualitatively using a thematic approach. Moreover, data triangulation was used to compile the results of the test and interview. The study explored the pronunciation, grammar, article, and alternative prepositional frameworks in learning the speaking skills of the English language among prospective teachers. Poor listening, traditional teaching methodology and interference of mother language were the major reasons for these alternative frameworks.

Published: February 2021

A global pandemic Covid-19 led countries to take aggressive action regarding social management and crisis governance management system. The case of a pandemic discovered in Wuhan provides a lesson for the government worldwide to adopt. However, the government system in every country has its characteristics. This study aims to release the potential policy recommendation in Indonesia when Indonesia's regional autonomy system faces a challenge in the pandemic situation, such as the increase of competition between regions. Even more, the public service system becomes concerned with the ego regionality. The strengthening country's capacity system is vital in the regional autonomy system as well as the collaboration between central and local government in terms of containment of the spread of the pandemic. Used a political ecology approach and a descriptive- review method, this study was conducted by discussing how the government responds in the regional autonomy system at the beginning of the pandemic situation. The review results show that the local government's response relies on their capacities, such as budget, human resources, and leadership. However, challenges arise when central and local governments' action is not in line in terms of the regional autonomy system. The public and political communication among central and local governments should be rearranged with an integration under proper management, particularly in the first month of the pandemic situation.
Intermittent fasting - a potential approach to modulate the gut microbiota in humans? A systematic review
Authors: Llewellyn-Waters Kate , Abdullah Mohammad M.
Published: February 2021

Research on gut microbiota has increased in popularity over the past decade, with evidence associating different dietary habits with changes in the makeup of the rich ecosystem of microorganisms that performs a variety of functions and induces a range of health effects, within and well beyond the gastrointestinal tract. Similarly, intermittent fasting (IF), an umbrella term describing various regimens of periods of voluntary abstinence from food and drink, has classically been associated with favourable impacts on cardiovascular risk factors, body weight, circadian biology, and, more recently, the gut health. The objective of this PRISMA systematic review was to summarize the peer-reviewed literature of clinical trials related to the impact of IF regimens on the gut microbiota. A MEDLINE search was conducted using PubMed and the keywords “intermittent fasting”, “gut microbiota”, “microbes”, and others. Whilst the field is still in its infancy, an emerging body of evidence suggests beneficial effects of IF on the health of the gut through increasing the microbial diversity and abundance, with possible clinical implications related to improving the immune function and ameliorating the metabolic status. Further research in larger clinical trials is warranted before practical recommendations for the public health can be made.
Guidelines on indicator methodology: A mission impossible?
Authors: Radermacher Walter J.
Published: February 2021

Indicators are part of daily life, modern politics and public debate in times of crises and their solutions. The question arises to what extent indicators embody a special form of statistical information, whether a separate indicator-chapter in statistical methodology is needed and what the content of this chapter should be. This paper considers different perspectives of indicators produced by official statistics agencies. Starting from the definition of indicators, it then discusses statistical quality, impact and interaction between producers and users of indicators. To introduce and illustrate the points made in the paper a choice of cases is used in order to derive the essential elements of a methodological framing. The overall objective is to enhance the added value of official statistics indicators as they are communicated and expected to lead to trustworthy evidence for policy making.
Multisensory balance training for unsteady elderly people: A scoping review
Authors: Yoo In-Gyu , Do Ji-Hye
Published: February 2021

BACKGROUND:

Posture control involves complex reactions of dynamic and static movements, and various sensory inputs. There is evidence that exercise using multisensory stimulation is moderately effective in improving the balance of the elderly.

OBJECTIVE:

The main purpose of this paper was to examine the existing literature to validate the effectiveness and applicability of multisensory stimulation training.

METHODS:

All relevant literature published as of June 1, 2020 in four prominent databases was searched (Embase, PubMed, PsycINFO, and Web of science) using the five-stage review framework proposed by Arksey and O’Malley.

RESULTS:

Multisensory stimulation training was more effective when vestibular and somatosensory were combined with visual stimuli, and differences in effectiveness compared to the effectiveness of existing treatments were confirmed. However, most of the reviewed papers are compared to simple strength training, and studies that compare the effects of multisensory stimulation training by setting a control group are still lacking.

CONCLUSION:

Further research is required to further elucidate the training conditions and treatment environment for multisensory training for the elderly at risk of falls and to provide strategies to improve treatment methods. In addition, a study that can evaluate user satisfaction in a way that best shows the treatment effect using qualitative research methods will be needed.
Inflation Dynamics, Globalization and Monetary Policy: Empirical Evidence from Selected South and Southeast Asian Countries
Authors:   Queen Mary College, Lahore., Shahid Arshi , Syed Shabib , Ahmad Hafiz
Published: January 2021

The present study investigated the impact of monetary policy and globalization on inflation. The study utilized an updated measure of globalization along with two other dimensions i.e., de facto and de jure measure of globalization to examine the nature of the globalization-inflation relationship. It measures the impact of monetary policy variables on inflation, ignoring random shocks as these are considered minor fractions for the inconsistency of the policy instruments. The study also used the Hodrick Prescott filter to calculate the domestic output gap to assess the notion that the changes in the domestic output gap are still relevant to inflation variations in the presence of globalization. Structural modeling of dynamic heterogeneous panel data estimation technique, which accounts for endogeneity and serial correlation issues has also been employed. The results of the study confirm that both global and domestic factors have significant and descriptive power for domestic inflation. Furthermore, the interest rate is found to be a major nominal anchor to affect inflation. The results of panel causality showed that there exists bidirectional causality from inflation to interest rate, while mixed results were found for analyzing monetary aggregates, exchange rate, globalization, and domestic output gap relationships.

Authors: Monzon Barbaro I , Ortega Maria Del Carmen , Goosen Jacques , Doll Dietrich , Moeng Maeyane Stephen
Published: January 2021

Background: An Emergency Room Thoracotomy (ERT) is a resource-intensive, high-risk procedure in which rapid decision-making is essential. In a resource-constrained system, identification of the group of patients that could achieve the best outcome will avoid futile use. Incorporating physiological and metabolic parameters at the time of arrival to the emergency department into the management algorithm may assist with better patient selection and could improve outcomes.

Material and Methods: A retrospective review of the results of subjects who underwent Emergency Room Thoracotomy at a Level 1 Academic Trauma Center over a 13-year period (01 January 2005 to 31 December 2017) was conducted. Mechanism of injury, physiological and metabolic parameters, anatomical injuries, Injury Severity Score (ISS), calculated Revised Trauma score (cRTS), volume and type of fluids administered, and mortality were analyzed comparing survivors and non-survivors.

Results: One hundred and ten (n=110) patients underwent ERT during the study period. Variables such as the mechanism of injury, physiological and metabolic parameters, type, and volume of fluids administered did not show any statistically significant influence in the final outcome. Penetrating cardiac and chest trauma had better survival (40.6 % and 20 % respectively) compared to those with thoraco-abdominal, abdominal, pelvic, and femoral vessel trauma. Overall survival was 21,8%.

Conclusions: In a resource-constrained environment an Emergency Room Thoracotomy should be performed in patients with a thoracic injury, especially cardiac, to achieve the best possible outcome.
The intensity of the processes of lipid peroxidation in the blood of cows in experimental fasciolosis
Authors: Freiuk D. V. , Stybel V. V.
Published: February 2021

Among the most common pathologies of parasitic etiology in ruminants, trematode diseases, namely fasciolosis, occupy a prominent place in terms of the degree of damage and economic damage caused. Activation of lipid peroxidation processes plays a significant role in the mechanisms of the development of fasciolosis in animals. The research aimed to investigate the level of lipid peroxidation products in cows' blood in experimental fasciolosis. For the test, 12 cows of 4–5 years of age, black-spotted breed, were selected, from which 2 groups were formed, six animals in each. Animals in the control group were clinically healthy. Animals of the experimental group were experimentally infected with adolescents. During the research, the rules of compulsory experiments were followed – selecting and keeping analog animals in groups. The cows' diet was balanced in terms of nutrients and minerals. Based on the studies, it was found that after the experimental infestation of cows of the experimental group with the causative agent of fasciolosis, an increase in the level of diene conjugates of their blood on the 15th day of the experiment by 30.3 %, and on the 25th day – by 50.4 % relative to the control group. There was also an increased level of lipid hydroperoxides in their blood, where, respectively, on the 10th and 15th day of the experiment, this figure increased by 18.3 and 32.9 % compared with the control group. On the 25th day of the experiment, the level of lipid hydroperoxides in the blood of cows of the experimental group was the highest. Compared with the control group, it increased by 46.6%, respectively. In the study of the final products of lipid peroxidation, it was found that on the 10th day of the test, the level of TBA-active products in infected cows of the experimental group increased by 9.5 %. On the 15th and 20th days of the experiment, the level of end products of LPO in the experimental group's blood of animals was higher by 20.3 and 26.0 % relative to the control group. The increase in TBA-active products' level reflects the activation of peroxide processes in animals with experimental fasciolosis. Therefore, in the clinical manifestation of fasciolosis, parasites secrete metabolic products that promote the formation of free radicals, which in turn enhance the initiation of lipid peroxidation processes.

Exploring the asymmetric coding of autobenefactive in Lithuanian and beyond
Authors: Panov Vladimir
Published: February 2021

In this paper, I investigate a group of semantically close functions marked by the Reflexive marker in Lithuanian, which I address as autobenefactive. I provide a classification of these functions and then turn to a marking asymmetry which is characteristic of the them, namely the tendency to occur in perfective contexts and not to occur in progressive contexts. On the basis of a questionnaire, I show that this tendency indeed exists, although different verbs are involved to different degrees, and we are presumably witnessing an ongoing grammaticalization process. I then compare the Lithuanian marking asymmetry to a phenomenon in Georgian, in which the use of “subjective version” exhibits a similar kind of asymmetry with some groups of verbs. In the concluding section, I propose a typological explanation of the observed asymmetry, hypothesizing that the markers of both languages function in a way parallel to so-called “bounders” – telicizers with primary spatial meanings.

CFD analysis of unsteady propeller performance operating at different inclined shaft angles for long-tail boat in Thailand
Authors: Kaewkhiaw Prachakon
Published: February 2021

Inclined shaft propeller arrangements are demonstrated in the high-speed boat. The flow field around the propeller blades with inclined shaft propeller is unsteady due to the cross-flow component from the influx of the shaft direction which complicated more than the straight shaft propeller condition (without inclined shaft propeller). Therefore, realistic flow around inclined shaft propeller is important to the actual efficiency of propeller. In addition, propeller characteristics such as the pitch, skew and rake are influences to propeller performance, maybe not done in design condition which is different from the straight shaft propeller. This paper offers the investigation of unsteady propeller performance with operating the different inclined shaft angle conditions for Long-Tail Boat (LTB) using a Reynolds Averaged Navier-Stokes (RANS) solver. The unsteady calculations are conducted by inclined flow conditions. The computational results of propeller performance and pressure distribution on the suction and pressure sides at the blades of time-accuracy have been compared to each other including the wake effect behind the propeller. The results can be applied to adjust the inclined shaft angle of the boat.
Self-determination about the future profession of young children with different kinds of gifted gift
Authors: Sadova Myroslava
Published: February 2021

The article analyzes the problem of self-determination regarding the future profession of young children with different types of talents (academic, creative, intellectual).
Self-determination regarding the future profession is the main prerogative of student development. If we consider the category of gifted students, their self-determination may not be easy, because teachers, psychologists, social workers will deal with "special" children who belong to the group "at risk". We call gifted children "special" because their psychological qualities can be extremely unstable to external stimuli. Such children have difficulty adapting, are often hated by others, do not understand peers because they are gifted.
Theoretical and methodological analysis of self-determination regarding the future profession of young children with different types of talents (academic, intellectual, creative) allows to record several theories and approaches, namely: the concept of "productive" thinking M. Galchenko, typology of professional self-determination E. Klimov, the concept of psychology B. Tsukanov, the concept of professional development of future psychologists J. Verna, the theory of intelligence A. Binet, the concept of gifted famous dynasties F. Galton, the concept of self-realization A. Maslow, the theory of intelligence J. Guilford, the concept of emotional intelligence O. Chebykin, the concept of intelligence D Wexler, J. Holland's concept of professional self-determination and no.
The definition of physical, social and emotional intelligence is given.
Physical intelligence - innate, from the standpoint of inclinations is argued as generally introduced into science.
Emotional intelligence, from our point of view, is a type of intellectual ability that allows a person to control their emotions, where to restrain them, to tolerate them in verbal color in order to interest the interlocutor.
Social intelligence is due to the fact that a person in social contacts with people finds different ways out of difficult situations.
Differential differences between the following concepts are given: abilities, inclinations, intellect, convergent and divergent thinking, giftedness, genius.

Abstract: The human eye can distinguish objects from digital images, however, computers do not have the ability as human eyes that can directly distinguish objects from digital images. Therefore the bag of visual words method was created. Bag of visual words is a method for presenting digital images based on local features. Bag of visual words illustrates how an image can be taken its characteristics, so that computers can distinguish objects on digital images. The test results show that the bag of visual words are still not maximal in classifying digital image categories, especially the chair category, which is only able to produce the most accurate accuracy of 75%.

Abstract: Payroll is an acceptance in return from the employer to the employee for a job or service that has been done and is expressed or valued in the form of money determined on the basis of an agreement or legislation and is paid on the basis of an employment agreement between the employer and the employee including benefits, both for the employees themselves and for the family. This research takes place at PT. Astro Niaga Jaya. The payroll process at PT. Astro Niaga Jaya is still conventional. Salary calculations are based on different details that hinder the performance process of the human resources department. Errors in calculating salaries can be fatal because it will affect the preparation of financial statements. Therefore, it is necessary to have an employee payroll information system so that the human resources department is not wrong in collecting employee payroll data. The purpose of this paper is to design employee attendance and payroll information systems at PT. Astro Niaga Jaya using Waterfall method in order to produce information that is fast, precise and accurate. The Waterfall method is often used in designing an information system. Payroll Information System can work effectively and efficiently.            Keywords: payroll, information, system
Comparative Assessment Of Light-based Intelligent Search And Optimization Algorithms

Published: February 2021

Classical optimization and search algorithms are not effective for nonlinear, complex, dynamic large-scaled problems with incomplete information. Hence, intelligent optimization algorithms, which are inspired by natural phenomena such as physics, biology, chemistry, mathematics, and so on have been proposed as working solutions over time. Many of the intelligent optimization algorithms are based on physics and biology, and they work by modelling or simulating different nature-based processes. Due to philosophy of constantly researching the best and absence of the most effective algorithm for all kinds of problems, new methods or new versions of existing methods are proposed to see if they can cope with very complex optimization problems. Two recently proposed algorithms, namely ray optimization and optics inspired optimization, seem to be inspired by light, and they are entitled as light-based intelligent optimization algorithms in this paper. These newer intelligent search and optimization algorithms are inspired by the law of refraction and reflection of light. Studies of these algorithms are compiled and the performance analysis of light-based i ntelligent optimization algorithms on unconstrained benchmark functions and constrained real engineering design problems is performed under equal conditions for the first time in this article. The results obtained show that ray optimization is superior, and effectively solves many complex problems.

Published: February 2021

In this study, a simulation study was conducted for the loss of efficiency caused by the heat emitted by the LED chips. The temperature change of LED luminaire was analysed for three different scenarios using finite element method. Due to the increase in the internal temperature of the luminaire and due to the air effect inside the LED luminaires, failure of the LEDs has been tried to be prevented. For this purpose, a passive cooling method was proposed in the simulation environment. So, in high power LED luminaires, the high heat emitted by the LED chips is reduced to low heat by an air flow method. In this way, efficiency in LED outputs has been achieved.
A Novel Cost-efficient Daylight-based Lighting System For Public Buildings: Design And Implementation

Published: February 2021

In this study, design and implementation of a new cost-efficient daylight-based lighting control system is proposed to provide energy saving in a public building with a conventional lighting system. Energy gain recovery and regional daylight utilization coefficients are obtained by conducting daylight measurements in all indoor spaces of the building where the proposed lighting system will be applied. Daylight value is continuously transferred to the control system through the pyranometer placed outside and the need for artificial lighting is calculated by using sectional daylight utilization coefficients. Thereby, maximum benefit from daylight is realized when unnecessary energy consumption for artificial lighting is reduced. Experimental measurement results show that the proposed daylight-based lighting control system provides an average energy efficiency of the building at the level of 60 %. Additionally, the required investment, such as operating cost and payback period for converting an existing conventional lighting system into the proposed system, are discussed in detail. Cost analysis shows that the payback period of the proposed system can be reduced by 5 years compared to the conventional system.
