The libraries of Kaunas university faculties and their subunits

In this article, the work of the libraries of Kaunas University faculties up to 1940 is analyzed. Their principal task was to provide readers with scientific and educational literature. The Technical Faculty, Theological-Philosophical Faculty, Faculty of Law, and Faculty of Humanities possessed the largest libraries. Other faculties organized libraries and collections of printed materials (no more than 1000 copies) in departments, laboratories, and for studies and seminars. The acquisition funds were assigned by the State Budget. Acquisition sources included bookstores, international library loans, and gifts. The libraries of the faculties operated independently until 1940. They assisted the Central Library of Kaunas University in providing its readers with literature necessary for studies. The libraries also took part in the pedagogical and scientific work of Kaunas University.

Machine learning methods as auxiliary tool for effective mathematics teaching

AbstractSeeing mathematics teaching as a very demanding and responsible process while having in mind the importance of mathematical knowledge for students of technical faculties, this paper aims to present heuristics for student classification according to their predicted mathematical success. Over the last few decades, the process of informatization of universities has resulted in new challenges universities are faced with. Due to the widespread use of educational databases, which opens new possibilities for educational data mining and analyses, machine learning algorithms have become a very popular tool for predicting students' academic performance. The decision tree algorithm is used in this paper for the classification and prediction of students' mathematical performance and it is trained on the data collected from the educational information system. The experimental results show that the model accuracy is 72% with an error rate of 0.28. The implementation of the Decision Tree Model to predict whether a student will pass, fail or be conditional in mathematical courses is important for both teachers and students, as well as for universities. Students' performance is one of the major keys in evaluating the quality of the teaching process, but also for evaluating the overall success of the university itself. As mathematics is considered a basic and important discipline, it is clear why predicting students' mathematical achievement is crucial for all levels of university organization.

Reflection of the sustainable urban mobility paradigm shift in teaching at three European universities

Over the last few decades, the urban transport planning framework has changed significantly towards sustainable mobility planning. It brings new requirements for the education of transport experts. In the paper, we discuss the future of academic education concerning these changes based on case studies of two prestigious technical faculties in Germany and Poland and a social science faculty in Czechia offering study programmes related to sustainable urban mobility planning. We applied a self-assessment questionnaire to investigate how the study programmes prepare future mobility managers and present the concept of sustainable mobility to students. Our results show that the existing study programmes do not cover all steps of sustainable urban mobility plan development. We identified a few gaps common to the technical and social science faculties, such as consensus-seeking knowledge and methods, monitoring and evaluation tools and approaches, and the development of soft skills (presentation and communication skills and stakeholder involvement techniques).

Evaluation of the Digestibility of Diets Containing Soy Okara in Clarias gariepinus (Burchell, 1822) Fries Raised in a Controlled Environment in Benin

Aims: To evaluate the digestibility of diets containing soy okara in Clarias gariepinus fries. Study Design: Random complete block design. Place and Duration of Study: Laboratory of Hydrology and Wetland Research, Faculty of Sciences and technics, University of Abomey-calavi, between June 2019 and July 2019. Methodology: Four diets containing different levels of soy okara (0%, 10%, 20% and 30%) respectively noted T0, T1, T2 and T3 were tested. Twelve 40L tanks were randomly distributed into 04 batches with 03 repetitions for each of the 04 diets. The fries with an initial average weight of 10.47 +/- 2g were fed ad libitum three times a day (8 A.M., 12 P.M., 4 P.M.) for 30 days. Survival rate, cannibalism rate, average daily gain, specific growth rate, weight-length relationship, condition factor, consumption index, ingested protein, protein efficiency coefficient and digestive utilization coefficients were measured. Results: The specific growth rates (SGR) ranged between 2.25 +/- 0.165 and 2.58 +/- 0.115 with the best rate for the treatment containing 0% soy okara. The consumption index varied from 1.18 +/- 0.009 to 1.41 +/- 0.132 with the best index for the T3 treatment. Furthermore, the mortality rates were 0% for treatments containing 20% and 30% soy okara. The results indicate that it is possible to incorporate up to 30% soybean okara into the diet of Clarias gariepinus fry without hindering their zootechnical performance. The digestive protein utilization coefficients of the diets were calculated and are 95.12; 88.47; 92.21 and 90.37 for diets containing 0%, 10%, 20% and 30% soy okara respectively. Conclusion: The results demonstrate that among the different diets tested, treatment T2, containing 20% soy okara, proved to be the most favorable in terms of zootechnical performance. These results suggest that T2 treatment can be considered as a promising option for feeding Clarias gariepinus fries.

On the inductance of a Möbius strip

The work is devoted to the calculation of the self-inductance of the Möbius strip (MS), assuming that a self-contained surface current flows on its surface. Subsequently, the vector potential corresponding to this situation is expressed in cases where: (a) the surface current is constant (b) the surface current is inversely proportional to the length of the line along which it flows. The self-inductance of the MS is determined by the integration of the vector potential. From the derived relations, the inductance of the MS is determined by computer simulation at different values of the ratio of width and radius of the MS. The reference value to the results for MS is the calculated and shown inductance of the cylindrical surface with a surface current flowing around the circumference of its shell. In conclusion, simple relations are derived that enable quick calculation of the inductances of both the MS and the cylindrical surface from their geometrical parameters. The article is intended for students of mathematical-physical and technical faculties as well as for graduates of these faculties dealing with the issue of (meta) materials.

Suggestions and Solutions for Enhancing Active Commuting to the University of Maribor and Advancing CO2 Emission Reduction

This study investigated commuting behavior at four technical faculties (BCTF) in Maribor. The main aim was to provide suggestions and solutions for challenges related to active commuting to the BCTF, while promoting advancements in CO2 emission reduction. The research methodology was based on analyses of a questionnaire survey and calculations of CO2 emissions. The results indicate that implementing measures to promote walking, bicycling and the use of city and regional public transport, in conjunction with supportive housing and parking policies, has the potential to eliminate car trips within 0–1 km of the BCTF and reduce car trips from other zones in favor of active commuting by 30% to 50%. These proposed transport scenarios could lead to an annual reduction in CO2 emissions ranging from 17% to 29%. The greatest potential for CO2 savings is observed within 0–5 km of the BCTF, where a shift to walking and bicycling could reduce emissions by up to 44%. The results also highlighted a notable disparity, indicating that students with term-time accommodations emitted 3.5 times and 4.1 times less annual CO2 within 0–5 km of the BCTF compared to students and staff commuting daily from their permanent residences in the city.

Chemical engineering in technical and technological culture

Modern technologies continuously change humans and their relationship with the environment. They can achieve a lot in the field of chemical engineering, thereby improving and enhancing the quality of human life, but on the other hand, technologies can be used to destroy human lives. Technical and technological culture (hereinafter referred to as TTC) is the entirety of social achievements in the field of technical and technological sciences and their application, as well as of the all knowledge and skills needed to understand the achievements, use them correctly, transfer them to the younger generation and create new values in this field. This paper will present a pilot study aimed to examine the attitudes and beliefs of engineers, Technological (chemical engineering) and Technical faculties, regarding the development of TTC and to determine socio-demographic factors that may influence its development. The research was conducted in Serbia and Croatia. The results indicate that the most important aspects of TTC are: the development of awareness of sustainable development, the impact on environmental protection, etc. The respondents recognized the ethical challenges we face today, the need for the education of young engineers and the promotion of TTC in the media and professional public.

Problem-Based Learning Approach Facilitating Sustainable Waste Management

This work provides inspiration to foster Problem-Based Learning (PBL) in teaching practices related to waste management. Problem-Based Learning is about providing a learning environment where students can work practically and theoretically with problems of relevance for society. In this learning process, students themselves will define societally important problems and direct the problem identification, problem analysis, and problem-solving processes. The PBL approach at the engineering and technical faculties at Aalborg University acts as a case of inspiration to exemplify how the structure of a problem-based project can foster students’ competencies and agency to contribute to a circular economy related to waste.

A statistically analysis to determine the use of renewable sources for campus lighting, case study of technical faculty of Kosova

<span lang="EN-US">Considering the ever-increasing demand for electricity and the current crisis in this sector, various ways of generating electricity have been studied. Most of them are based on hybrid technologies as a solution to replace the relevant resources during the absence. In Kosovo, as an economically poor country, such technologies are rarely used. Public lighting in some countries is still considered unaffordable due to high cost. This study further demonstrates an environmentally friendly option for power generation using hybrid PV and Wind systems. The current study presents the study that was carried out on the campus of the technical faculty in Pristina. The analysis has been done analytically, which has resulted in the need for 6 hybrid lighting systems to achieve a coverage of the lighting needs, which so far lacks lighting in this part of the campus. A total of 461,448 kWh can be generated during the year from the wind turbine system and 796.11 kWh from the solar photovoltaic system. Considering that we have an ever-decreasing cost of such devices and from the analysis done it results that these systems are cost effective and ideal solutions for such cases and similar needs which are vital needs today.</span>

Značaj mehkih vještina u osnaživanju mladih kroz obrazovanje

This paper explores the importance and role of soft skills in the context of education and career development. Education, as a key stage in the process of accumulation of knowledge and skills, constitutes a fundamental experience in the formation of individual competencies. In most of their lives, individuals devote considerable time and intellectual energy to the process of education, within which they acquire various forms of knowledge and skills. The acquired knowledge and skills then become key elements that shape their future professional career. But what separates highly successful individuals from the rest is often not the technical competencies acquired through formal education, but the so-called “soft skills”. Research on this topic becomes imperative in order to better understand the impact of soft skills on the performance of individuals in order to develop strategies to improve these skills. This paper recognizes the key role of soft skills in education and encourages further research to better understand their importance and to ensure that these skills are comprehensively incorporated into educational and professional programs. The research was conducted on a sample of students from the technical faculties of “Dzemal Bijedic” University of Mostar.

Early Engineers and Architects Born on the Territory of Present North Macedonia

This article presents the initial results of the ongoing research into the early engineers and architects born in the past on the territory of present North Macedonia, who graduated before the establishment of the country on 2 August 1944, prior to the founding of the first Technical Faculty in Skopje in 1949. The majority of the identified engineers and architects were men who graduated within the interwar period from the Technical Faculty at the University of Belgrade (Serbia), founded in 1846. Women started entering engineering and architecture in the 1930s. Some of the early graduates pursued their professional careers elsewhere. Three graduates of Riga Polytechnic Institute (Latvia) were identified, who had their degrees recognized by the Technical Faculty in Belgrade, as well as one Serbian woman, an engineer, and an architect who briefly lived in Riga within the researched period. This study contributes to the history of engineering and architecture in North Macedonia.

The choice of a technical specialty by students of Russian universities: generational analysis

The article deals with the inheritance of technical professions for three generations of the family. The relevance of the study is due to the need of studying the influence of the family on the educational, professional, and cultural capital of students. The main issues of the project are the educational and professional paths of several generations of the family, family capital, motives for choosing a technical profession by students of Russian universities, dynasties of technical specialists, the collection of biographical works as a method of empirical sociology. The autobiographies written by the students of technical specialties of Russian higher educational institutions were analyzed. The educational experience of parents, grandparents of informants was studied. The author presents the classification of professions of the older generations of the family. The texts were processed using specialized computer programs. It is established that the technical profession is leading in the list of occupations of the older generations of the students' family. The second place is occupied by workers in the field of economics. In the dynasties of technical specialists, the main factor in choosing a profession is the inheritance of family professional, educational, cultural and social capital. In other families, the main motives for choosing a technical education and profession are the abilities and interests of the student, as well as the prospects of a high income. Inheritance of a profession closes the ranking of reasons for admission to technical faculties. A methodological analysis of the collection of biographical works was carried out. The approach minimizes the presence of the researcher at the field stage of the project implementation, allows the use of computer text processing, is relevant to the study of generational issues in sociology. Among the disadvantages of the method is the incompleteness of the primary information received. The results of the project can be used to solve the tasks of social policy in the fields of labor, education and family. The experience of generational analysis of biographical materials is important to sociology.

Risk analysis of construction a logistic centre in economic and environmental aspects

Purpose: The article attempts a qualitative risk analysis of the feasibility of the construction project of a logistics centre (a warehouse hall with a monolithic reinforced concrete structure), with particular emphasis on the implementation phase. Risk factors may have a negative impact on individual stages of the investment process, and when detected at the right moment, they can be minimized - which will beneficially contribute to changing the investor's risk level. Design/methodology/approach: The influence of selected risk factors on the scope of works carried out during construction was examined. Particular attention was paid to the time and cost of the investment implementation as well as its impact on the nearest natural environment. The analysis was carried out using modern tools supporting the engineer's work, including computer methods. The Norma PRO 4.75 cost estimating program was used, Microsoft Project supporting project management in terms of resources, time and finances, and Risky Project 7.2 used to manage project risk. Findings: The components of the construction process that are most exposed to the risk of failure were identified, and preventive measures should be taken against them. The main factors threatening the implementation of the project assumptions, having a significant impact on the extension of time and the increase in the costs of feasibility, include the risk of equipment failure, the risk of employee absenteeism and the risk of negative impact of the works carried out on the immediate natural environment. The key processes in the construction of the logistics centre turned out to be foundation works and assembly of structural elements, due to their complexity, labour-intensity, implementation time and high costs. Research limitations/implications: Research limitations result from the analysis of a deliberately selected case, which does not allow for formulating general conclusions. Nevertheless, the article refers to engineering practice and describes the challenges faced by the construction sector in the logistics industry. Practical implications: The information contained in the publication may be of interest to representatives of the business sector, students and doctoral students of technical faculties, analysing the impact of sustainable development on warehouse infrastructure and innovation of project systems in the national and international dimension. Originality/value: The publication covers the subject of construction logistics in the process of implementation of the project, as well as an analysis of selected risk factors, their definitions, and its reduction possibilities. Based on the project a qualitative risk analysis was performed, the result of this analysis was the identification of risks for which preventive measures should be introduced. After identifying the risk, it is recommended to be thorough estimation of risk factors and their evaluation, as well as planning the response to risk based on the selected model. Keywords: construction economics, infrastructure and environment, logistic centre, risk management. Category of the paper: Case study.

The use of social media by Polish and Slovak students and their digital competences

In this study, the main goal is to indicate the differences between the use of SM by Polish and Slovak students and the relationship between the use of SM and digital competences. A questionnaire survey conducted among Polish and Slovak students of technical faculties was used to obtain the data. The analysis was performed using the methods of multivariate statistical analysis. The study was conducted in October-December 2018 in parallel in Poland and Slovakia. In the course of the study, 172 questionnaires were returned from students from Poland and 171 from students from Slovakia, representing a manoeuvrability of 49% and 65% respectively. The main finding of the research on the use of SM is the more frequent use of SM by Slovak students. The results showed that Twitter and Instagram (after Facebook, which was used by over 98% of respondents) are more often (significantly) used by Slovak students, and YouTube and WhatsApp by Polish students. Our results also show that information competences demonstrate much less correlation with the use of social media compared to IT competences. The presented research results aim to fill the gap focusing on finding a relationship between the use of SM and digital competences. This approach results primarily from the universal use of SM and the need to develop competences that are the basis for effective functioning in the professional and private sphere in the era of digitization.

Beogradski opus arhitekte Milutina Jovanovića (1930-1941)

Milutin Jovanović belongs to the generation of architects who significantly contributed to the urban and architectural development of Belgrade between the two world wars. However, since there has been no adequate valorization of his creativity, a complete list of his achievements and basic biographical data have remained completely unknown. By reconstructing Jovanović's works, chronologically systematized data about his movement in the architectural profession was obtained. He began his professional engagement as an assistant at the architectural department of the Belgrade Technical Faculty, and later devoted himself to private practice. During the entire interwar period, Jovanović designed dozens of residential buildings and one hotel, and was also dedicated to other design tasks. He was hired by wealthy representatives of the middle class - merchants, clerks, doctors, entrepreneurs and many others, for whom he designed predominantly representative high-rise residential buildings throughout the central city core. In accordance with the developments on the architectural scene of that time, respecting the requests of the clients, his achievements were in two dominant stylistic directions - academicism and modernism. The discovery of buildings designed in the spirit of modernism is particularly significant, because for a long time it was considered that Jovanović's main style was academicism. Given the lack of personal legacy and complete historiographical sources, the research was based on studying of the fund of the Technical Directorate of the City of Belgrade stored in the Historical Archive of Belgrade. Therefore, this work is the first monographic review of the life and work of the architect Milutin Jovanović.
