Published: June 2023

Abstract
In sheet metal forming processes, friction increases the force parameters of the forming process and produces a deterioration in the quality of the surface of the components. The basic way to reduce the unfavourable impact of friction is to lubricate the sheet metal surface with commercial oils. This article presents the results of experimental studies and analysis of variance (ANOVA) of the friction of DC01 low-carbon steel sheets using a strip drawing test. For these tests, a special device was built containing countersamples with a flat surface made of 145Cr6 steel covered with a protective AlTiN coating. Lubricants of different viscosities were fed into the contact zone under forced pressure. The effect of contact pressure on the value of the coefficient of friction was also determined. The predicted R² of 0.9227 was in reasonable agreement with the adjusted R² of 0.9411 confirming that the ANOVA model was reliable. It was found that increasing the lubricant pressure had a beneficial effect in reducing the value of the coefficient of friction. The higher the contact pressure, the more effectively the pressurised oil reduced the value of the coefficient of friction.

A Comparative Analysis of the Corporate Ideologies of Banks Operating in the Republic of Croatia
Authors: Lacković Stjepan , Baralić Marina , Šporčić Mateja 
Published: June 2023

Abstract

Research background
Corporate ideology is perceived as a set of fundamental beliefs held by company members about how the company and its members should behave in relation to one another and the outside world. In this paper, corporate ideology is treated as the basis for creating an organization’s identity and as an extremely important factor in its success.

Purpose
The aim of this paper is to analyze the corporate ideologies of banks operating in the Republic of Croatia, to classify different ideologies, and finally, to determine what kind of identity the surveyed banks communicate through their corporate ideologies.

Research methodology
A comparative and content analysis are applied as qualitative methods of research of an interpretative character.

Results
The corporate ideologies of two of the analyzed banks (ZABA and Erste) are described as social institutionalism, and PBZ’s ideology is labeled as social corporatism. Detected corporate ideologies do not serve to build the authenticity of banks’ identities.

Novelty
The main novelty of this research is in the methodology of reaching corporate ideologies. Unlike previous works on corporate ideology, in this paper public messages communicated in (digital) media were the main sources for the analysis of an organization’s core values and ideologies resulting from it. Also, a simple framework for the possible classification of different corporate ideologies was provided.
Confronting the Inflationary Pressures of Introducing the Euro with the Effects of Negative External Shocks
Authors: Biškupec Petra Popek , Ružić Ivan 
Published: June 2023

Abstract

Research background
with the introduction of the euro as the domestic currency, economies have faced inflationary pressures caused by price convergence towards higher levels. During the last period of significant negative shocks from the environment, by entering the euro area, the negative effects of the likelihood of inflation caused by the introduction of the euro may be absent.

Purpose
the aim of this paper is to prove that inflation caused by joining the euro area will not materialize due to the negative effects of external shocks.

Research methodology
A panel analysis with a fixed effects model was conducted for two models. Model 1 represents the countries that introduced the euro before the escalation of the global financial crisis and Model 2 represents the countries that introduced the euro after the development of the global financial crisis.

Results
the research confirmed that due to current negative external shocks and rising long-term interest rates in financial markets, the effect of inflation due to the introduction of the euro will be absent among EU members that will adopt the euro as a common currency in the next few years.

Novelty
The results of the research contribute to the scientific prediction of business and financial trends. The creators of macroeconomic models and monetary policy can use the results to define measures, instruments and activities more precisely for achieving and maintaining macroeconomic balance.
AD-AS Analysis from the Perspective of Functional Finance Theory and MMT
Authors: Tanaka Yasuhito 
Published: June 2023

Abstract

Research background
In the past few years, MMT (Modern Money Theory or Modern Monetary Theory) has been increasingly discussed in Japan as well as in the U.S. However, both in the U.S. and Japan, analysis using mathematics is lacking and analysis using IS-LM and AD-AS analysis methods in macroeconomics is almost non-existent.

Purpose
We present an AD-AS analysis from the perspective of Functional Finance Theory and MMT (Modern Monetary Theory).

Research methodology
Graphical analyses with some mathematical analyses. Mathematical analyses include graphic analysis using AD and AS curves and calculations to derive equations representing them based on models of consumer and firm behavior.

Results
Using an overlapping generations model under monopolistic competition we show the following results by calculations and graphical analyses.
1. The budget deficit (including interest payments on government bonds) equals an increase in the savings of consumers from period to period. This result means that the debt-GDP ratio would not diverge to infinity, but would remain at a finite value whether the interest rate of government bonds is larger or smaller than the growth rate.
2. We need a budget deficit (including interest payments) to maintain full employment without inflation under economic growth. However, if the interest rate of government bonds is larger than the growth rate, we need a budget surplus (excluding interest payments) to maintain full employment without inflation.
3. A return to full employment from a recession can be achieved by implementing the appropriate fiscal policies through increased government spending or tax cuts.
4. Excessive government expenditure or an insufficient tax under full employment induces inflation.

Novelty
This is probably the first AD-AS analysis done from the standpoint of Functional Finance Theory and MMT.

Abstract
Donkey welfare is becoming a subject of much interest; for decades, people around the world have voiced rising worry about it. There are no studies on donkey welfare in Nigeria. This study aimed to assess the welfare state of donkeys in Amaru, Zaria Ancient City, Kaduna State, Nigeria. A cross-sectional study was done to purposefully select 38 pack donkeys for welfare assessment based on the first level of the Animal Welfare Indicators (AWIN) for donkeys, which covered behaviour, health, feeding, and environment and housing. Information regarding age and sex was collected. The analysed data were reported in terms of frequencies and percentages. The prevalence of donkeys with no social contact, avoidance behaviour, and walking downside was 2.6 %, 5.36 %, and 40.56 %, respectively. The most common health problems are integumentary alterations, which include an unhealthy hair coat (86.8 %), skin lesions (86.6 %), alopecia (60.5 %), and deep wounds (47.4 %). Only 5.3 % of the donkeys were lame. Around 42 % had a body condition score of 2 (moderate), while the remaining 57.9 % had a body condition score of 3 (ideal). The donkeys were poorly kept and housed, as evidenced by the high prevalence of unsatisfactory shelter dimensions (100 %), dirty bedding (89.5 %), and insufficient bedding (89.5 %). The current study found that welfare issues are serious challenges for donkeys in Amaru, Zaria Ancient City, Kaduna State, Nigeria. As a consequence of the current findings, it is recommended that donkey welfare, policies and legislative frameworks that support animal welfare and inspect animal facilities in Nigeria should to be reviewed and enforced.

PEDAGOGICAL BIOGRAPHY AS A PROBLEM OF SCIENTIFIC RESEARCH AND EDUCATIONAL PRACTICE IN THE CONDITIONS OF AN INSTITUTION OF HIGHER EDUCATION
Authors: Koliada Natalia 
Published: June 2023

The article reveals the phenomenon of pedagogical biography as a problem of scientific research and educational practice in the conditions of a higher education institution.In the conditions of the accumulation of biographical information, the development of theoretical and methodological foundations of scientific research, it is relevant to study the issues of pedagogical biography as a field of scientific creativity, publishing and information work, biographical studies of the activities of teachers, educators, and public figures at a certain historical and pedagogical stage.Among the main tasks of Ukrainian pedagogical biography as a component of national memory is the disclosure of the life-creating path of personalities for the sake of a holistic presentation of the process of development of humanistic pedagogy in Ukraine.The relevance of the issue of pedagogical biography is enhanced by its multidimensionality as a pedagogical, historical, social phenomenon that requires a thorough study in order to represent it representatively in the modern interdisciplinary historical and cultural discourse - educational, socio-pedagogical, historical-pedagogical, etc.The author, based on the analysis of general approaches to the study of interdisciplinary problems of pedagogical biography, characterized the activities of the Scientific Research Center of Pedagogical Local Studies under the dual subordination of the National Academy of Sciences of Ukraine and the Ministry of Education and Culture of Ukraine at Pavlo Tychyna Uman State Pedagogical University.
The results of the Center's many years of activity confirm the opinion that at the current stage of society's development, the cooperation of higher education institutions with scientific institutions is gaining relevance and vital necessity. In particular, an important direction of such cooperation is the integration of education and science in the conditions of a higher school for the purpose of holistic presentation of the process of development of science, education and pedagogy in Ukraine. Therefore, the prospects for further scientific research are to strengthen interdisciplinary research on topical issues of the development of Ukrainian pedagogical biography as an important component of national memory.
