AbstractFor low Earth orbit (LEO) satellites, solar panel is a firstly key device to convert the solar radiation into the electric power to supply the energy consume. However, the solar array is always suffering from the power degradation due to the harsh space environments. To meet the power balance in the end life of the spacecraft, attitude determination and control system (ADCS) plays an important role in the solar panel direction to change the solar energy input. Here, the solar cell performance parameters from an LEO satellite running on a dawn-dusk Sun synchronous orbit (SSO) are investigated. A yaw maneuver application is presented to satisfy the electric power supply (EPS) risk of the solar cell current decrease. Validated in the space operation, the results have shown that in the yaw mode, the EPS output is improved and the solar cell current is averagely enhanced more than 10% when the orbit incidence is 35°. The yaw maneuver is applied to the state of health (SOH) management with a better power supply. The solution can be widely and usefully taken into account to increase the solar array output for a near-Earth satellite in the risk of the power shortage.

Authors: Khac Hoang Nguyen , Modabberian Amin , Storm Xiaoguo , Zenger Kai , Hyvönen Jari 
Published: December 2021

Abstract
In this work, a model predictive controller is developed for a multiple injection combustion model. A 1D engine model with three distinct injections is used to generate data for identifying the state-space representation of the engine model. This state-space model is then used to design a controller for controlling the start of injection and injected fuel mass of the post injection. These parameters are used as inputs for the engine model to control the maximum cylinder pressure and indicated mean effective pressure.
The Nature and Status of Concepts in Phenomenology
Authors: Clarke Evan 
Published: December 2021

AbstractThis essay examines the debate that arose immediately following the publication of the first volume of Edmund Husserl'sIdeasregarding the model of concept formation that Husserl sketches in that work. After a brief overview of the relevant passages from theIdeas, I take up essay-length responses to Husserl by August Messer, Theodor Elsenhans, and Heinrich Gustav Steinmann. Reflecting a variety of empiricist commitments, all three authors are skeptical that concepts can be expected to embody the essence of a corresponding phenomenon. Subsequently, I review the responses to these critiques offered by Husserl, his then-assistant Edith Stein, and Paul Linke. For Linke, it is at least highly probable that certain concepts derive their content from an apprehension of essence. The empiricist alternative, he argues, is fatally unstable. Husserl and Stein, meanwhile, offer a more forceful defense of this position. Unless we allow that certain kinds of concepts can originate from a grasp of essence, they argue, we will be unable to explain how certain manifest cognitive accomplishments are possible.
Concrete anisotropy estimated from ultrasonic signal amplitudes
Authors: Ekin Nevbahar 
Published: December 2021

Abstract
The anisotropy of concrete is an essential issue in the construction industry. In this study, for the first time, ultrasonic compression and shear wave signals have been investigated for the orthogonal directions of unreinforced concrete by means of fast Fourier transformation (FFT). For this purpose, cubic concrete samples were prepared in 12 designs of different strengths for ultrasound transmission measurements. The characteristic amplitudes at dominant frequencies were determined by the FFT of these signals. The FFT amplitude differences in the compression and the shear wave signals on the orthogonally oriented surfaces provide essential information about the presence and degree of anisotropy. According to linear regression analysis, the FFT amplitude anisotropies and the amplitude ratios of the compression and shear waves decreased significantly according to increasing concrete strength. In addition, it was found that the anisotropy and the ratio of the FFT amplitudes increased proportionally to the water/cement ratio, the porosity and the water content of the various concrete designs.
Experimental evaluation and modelling of the boronizing kinetics of AISI H13 hot work tool steel
Authors: Abdellah Zahra Nait , Boumaali Brahim , Keddam Mourad 
Published: December 2021

AbstractIn the study for this contribution, the AISI H13 hot work steel was pack-boronized between 2 and 6 h of exposure time within the temperature range of 800 – 1000 °C. The boriding agent was composed of a powder mixture containing (in weight percent): 90 % of boron carbide (B4C) and 10 % of sodium tetrafluoroborate (NaBF4). The SEM observations showed a less pronounced jagged interface between the boronized layer and the transient zone. A double phase boride layer (FeB and Fe2B) was identified over the surface of AISI H13 steel with the presence of metallic borides inside this compound layer. The mean diffusion coefficient (MDC) method was applied to analyze the growth of iron borides (FeB and Fe2B) as compact layers over the surfaces of AISI H13 steel. The boron activation energies in the two iron borides were also assessed from the present kinetic approach by assuming the Arrhenius relationships. Afterwards, the kinetic model was checked experimentally by considering two extra boriding conditions (925 °C for 1 and 3 h). Finally, the predicted layer thicknesses are in accordance with experimental measurements.
Effect of Short Solution Heat Treatment Time on the Microstructure and Properties of Al-Si-Mg-Cu Alloys
Authors: Zhuang P. , Shi H. , Zhang Z. , Chai R. , Zan J. , Du X. 
Published: December 2021

Abstract
In this work, a solution heat treatment of Al-Si-Mg-Cu casting alloy was analyzed. A new short solution heat treatment (SHT) with only 60 min has been allowed. The results revealed that this short SHT enables the improvement of the dendritic structure and the spheroidization of the eutectic silicon particles. Furthermore, the alloy showed improved mechanical properties when compared to the same alloy subjected to a longer SHT of 4 h. It was observed that increasing the SHT temperature can accelerate the dissolution and homogenization of the silicon particles and intermetallic precipitates in the matrix.
Metallurgical Failure Investigation of Combustion Chamber Leakage in a Heavy-duty Gas Turbine Engine
Authors: Neidel A. , Gädicke T. , Riesenbeck S. , Wallich S. 
Published: December 2021

Abstract
In this contribution, a case study is presented describing the failure of a combustion chamber assembly in a non-OEM (Original Equipment Manufacturer) gas turbine engine used for power generation. It showed how even advanced fabrication methods, such as Electron Beam (EB) welding, could trigger fatigue fracture, even if there are no material defects, no weld imperfections, no fabrication flaws, and even if everything is within specified limits. As is so often the case in component failures, the fact that failures occur anyway, despite the absence of out-of-spec material properties, and even though there were no fabrication flaws, is attributable to the design; which is often not sturdy enough to withstand unexpected dynamic loading.
“Just taking part or fully participate with others!?”: Social integration of members with disabilities in mainstream sports clubs
Authors: Albrecht Julia , Nagel Siegfried , Klenk Christoffer 
Published: December 2021

Summary
People with disabilities still show lower participation rates in mainstream sports clubs. Even when they are members of mainstream sports clubs, their participation is often limited to structural integration, while broader social integration including cultural and affective dimensions is only partially achieved. Thus, this study analyses the broader extent of social integration of members with disabilities in sports clubs, applying Esser’s model of social integration, which is comprised of four dimensions: culturation, interaction, identification, and placement. The article describes multiple case studies conducted with this model on a sample of three mainstream clubs, including 14 members with disabilities. Results show overall high scores on the four dimensions, consequently pointing to effective social integration of members with disabilities. Moreover, the studies also reveal indications of factors that are relevant for social integration. This knowledge is helpful for clubs with regard to managing social integration strategies and practices.

Published: December 2021

Significance Statement
Many individuals with CKD are not receiving appropriate medical treatments. Behavioral economics interventions, such as nudging strategies, are reported to improve health-related behaviors. However, little is known about whether the nudge intervention increases the likelihood of individuals with identified CKD adhering to a recommended physician visit. In this randomized clinical trial, 4011 participants in CKD screens were randomly assigned to two interventions or the control: (1) the nudge-based letter, (2) the clinical information letter, and (3) the control. The probability of visiting the recommended physician was higher among participants who received the nudge-based letter or the clinical letter compared with the control group. We found no evidence for interventions associated with improved early health outcomes.

Background
Although CKD screening programs have been provided in many settings, little is known as to how we can effectively translate those screening programs into improved health.

Methods
We conducted a randomized clinical trial on national health screening for CKD in Japan between April 2018 and March 2019. A total of 4011 participants in CKD screening programs aged 40–63 years were randomly assigned to two interventions or the control, with a ratio of 2:2:1, respectively: (1) the nudge-based letter that contained a message on the basis of behavioral economics, (2) the clinical letter including general information about CKD risks, and (3) the control (informed only of the screening results). The main outcome was adherence to a recommended physician visit within 6 months of the intervention. The secondary outcomes were eGFR, proteinuria, and BP 1 year after the intervention.

Results
Compared with the control group, the probability of undergoing a recommended physician visit was higher among participants who received the nudge-based letter (19.7% for the intervention group versus 15.8% for the control; difference, +3.9 percentage points [pp]; 95% CI, +0.8 to +7.0; P=0.02) and the clinical letter (19.7% versus 15.8%; difference, +3.9 pp; 95% CI, +0.8 to +7.0; P=0.02). We found no evidence that interventions were associated with improved early health outcomes.

Conclusions
The behavioral economics intervention tested in this large RCT had limited effect on changing behavior or improving health outcomes. Although the approach has promise, this study demonstrates the challenge of developing behavioral interventions that improve the effectiveness of CKD screening programs.

Authors: Kuzmin P. S. 
Published: December 2021

Nowadays business processes in industrial companies are undergoing significant changes under the influence of the trends of the fourth industrial revolution, and the pace and scale of the spread of digital technologies has significantly accelerated due to the coronavirus pandemic. The technological basis for the digital transformation of industrial companies is the industrial Internet of things, cloud computing and blockchain, the collection of big data and their subsequent analytics, machine learning technologies, digital twins, human-machine interaction, including virtual and augmented reality, robotics and automation.Even though the technologies of the fourth industrial revolution can transform the activities of enterprises and increase their efficiency, today most of the projects do not move from the pilot stage to widespread implementation in the company. The purpose of this study is to identify and assess the main barriers that impede the successful implementation of digital technology implementation projects.At the first stage of the study based on a review of domestic and foreign literature, as well as in-depth interviews with experts, groups of barriers were identified and verified that impede the implementation of digital technologies in industrial companies: economic and financial, managerial, competence, regulatory and technological barriers. Also, questionnaires were developed for the quantitative stage of the study.At the second stage of the study, a quantitative assessment of the strength of the influence of barriers was carried out. The barriers with the greatest influence are lack of funds, the need to attract large amounts of funding, and insufficient support from the organization’s management. According to the analysis, the least significant barriers for companies include the complexity of introducing new technologies and the need to change the company’s business model.At the end of the work, a list of proposals was developed to overcome the barriers to the transition from the stage of pilot implementation of technologies of the fourth industrial revolution to widespread implementation.

Promoting a Better Image through Culture: The Case of Turkey’s Cultural Diplomacy towards Indonesia
Authors: Zaelani Rifkha Aulia Fazrianti , Sahide Ahmad 
Published: December 2021

This study attempts to reveal cultural diplomacy, which Turkey implements towards Indonesia. The ‘golden period’ of Turkey is from 2007 until 2013. After that, the public diplomacy of Turkey was not effective as before, and it was fallen dramatically. The country’s instability caused by the political turmoil within the country also influences the growth of international isolation. With these based on the problem that influences its image, Turkey needs to prove a different and better image to promote itself abroad. Public perceptions can be shaped and controlled by doing cultural diplomacy that acts as soft power. Having one thing in common as a country with a Muslim population as the majority, Turkey has a special place in the hearts of the Indonesian people. Based on the theory of cultural diplomacy by Milton C. Cummings, the authors drew two arguments. First, Turkey’s Cultural diplomacy towards Indonesia is done not only by state actors (officially by the government) but also by non-state actors such as individuals and companies. Second, cultural diplomacy carried out by Turkey towards Indonesia is through all aspects of the needs of the Indonesian people, such as films, fashion, news, music, food, and education.

Wpisana do preambuły Konstytucji RP zasada dialogu społecznego legła u podstaw stosunków w państwie. Analiza wpływu dialogu społecznego na relacje międzyludzkie skłania do refleksji na temat roli, jaką odgrywa on w rozwiązywaniu konfliktów społecznych. Artykuł przedstawia wyniki badań przeprowadzonych celem znalezienia odpowiedzi na pytanie o znaczenie dialogu społecznego w rozstrzyganiu sporów i rozładowywaniu napięć społecznych. W związku z tym zaprezentowane zostały formy, jakie przybiera dialog, próbując osiągnąć swój cel, jakim jest dążenie do zachowania pokoju społecznego.
Prezentując wyniki badań, należy zasygnalizować niepokojące zjawisko, jakim jest spłycanie roli instytucji dialogu społecznego. Marginalizacja dialogu społecznego, będącego jednym z gwarantów demokratycznego państwa prawnego, toruje drogę samowładztwu. Uznając kluczową rolę dialogu społecznego, jaką odgrywa w rozwiązywaniu konfliktów, zasadny wydaje się apel o jak najczęstsze uciekanie się do tych form rozstrzygania sporów, które są charakterystyczne dla dialogu społecznego. W artykule zachęca się do czynnego udziału w dialogu, a także przypomina o obowiązku do jego prowadzenia przez władze państwowe.

Authors: Vahanova L. , Potsiluiko К. , Yakobchuk N. 
Published: December 2021

Today, the current situation in the field of health care indicates the presence of at least two problems, such as poor quality of services and corruption in medical institutions. Today, local authorities have a responsibility to ensure that community residents have access to doctors and their services, as well as to improve the quality of medical services. The current work of scientists does not currently provide an answer to the essence of the new challenges and threats to the continued decentralization of health care that currently face the united territorial communities. The health risks that may arise in the process of continuing decentralization have been studied.
The authors present opportunities for the implementation of the powers of local governments to ensure health reform, as well as the sequence of actions of public health facilities and their owners since the decentralization.
MANAGING THE REPUTATIONAL RISKS OF THE COMPANY TAKING INTO ACCOUNT THE CONCEPT OF CORPORATE SOCIAL RESPONSIBILITY
Authors: Zhaldak H. , Chuprina М. 
Published: December 2021

The main stages that can be used to diagnose the level of development of the company's reputation are detailed. Thus, most of the enterprises engaged in corporate social responsibility initiatives are in the 2nd (32 %) and 3rd (36 %) stages, respectively. It has been established that in order to achieve a positive financial and economic effect from corporate social responsibility projects in the long term, it is worth implementing projects at the level of forming a strategy and developing an internal corporate culture. The influence of reputational risks on the development of business reputation has been substantiated.
The definition of reputational risks in the sphere of corporate social responsibility was clarified and the main characteristics of the stages of reputation risk management were considered. Based on research conducted by Global RepTrak (2019), the main areas of risk occurrence in the field of corporate social responsibility are highlighted. The practical significance of the results obtained lies in the fact that their application in the activities of companies helps to ensure the business reputation and capitalization of the company based on the use of the concept of corporate social responsibility.
Complex analysis of the state of the main elements of the mechanism for the development of the economic potential of the enterprise

Published: December 2021

The complexity of the relationship between the existing elements of the organizational and economic mechanism for the development of the economic potential of an enterprise, as an integral system, is revealed, which is a consequence of the fact that its individual subsystems and components are of a probabilistic nature. A comprehensive analysis of the state of the elements of the mechanism for the development of the economic potential of an enterprise is represented by types of analysis, objects of analysis, and the results of analysis. To determine the place of the organizational and economic mechanism for the development of economic potential, using the model of R. Solow, the qualitative and quantitative composition of the enterprise’s functions is investigated. Factor analysis according to the Solow model shows the special importance of modern scientific and technological progress, and the Solow remainder in his model reflects a number of other factors, including labor resources. The analysis shows that the overall economic growth in 2015-2019 cannot be compensated for only by an increase in labor and total capital. First of all, it can only be justified by the use of the state. The use of the Cobb-Douglas production function in the Solow model allows one to determine the nonlinear dependence of labor productivity on its capital-labor ratio. The Harrod-Domar model was also used, which showed that enterprises are able to provide capital gains in the current year through investments in the previous year. This was demonstrated by the example of the fixed capital of the country’s industry as an integral element of production potential.
Also, on the basis of the research, more generalizing conclusions can be drawn. The influence of industry on the national economy as a whole is as follows: the development of industry will stimulate the growth of other sectors of the economy through an increase in demand for their products and this will become the main catalyst for the development of the Ukrainian economy and will increase GDP; the growth of the industrial sector will increase the competitiveness of Ukrainian workers in the global labor market and reduce the unemployment rate; industrial development will increase the role of Ukraine in the international economic market and will increase the volume of foreign exchange earnings; industrial modernization and the introduction of high-tech production will increase the potential of the economy as a whole.
