Abstract
In the apparel manufacturing, the fabric is the single largest element in the cost of the garment. Therefore, effectual fabric consumption causes a reduction in cost and exertions. The purpose of this research is to study the effects of fabric width on the efficiency of marker (cutting) plans. Fabric consumption is in four types for human body shapes, that is, triangle, oval, square, and circle, in both genders to control the fabric utilization. Two clothing styles, fitted trousers and fitted shirts, are manufactured in an apparel manufacturing industry. The marker plans produced through Garment Gerber Technology software are accomplished in 36 different fabric widths (independent variables). The evaluation of dependent variables, that is, marker efficiency, marker loss, and fabric consumption efficiency relevant to four body shapes in variable fabric widths is analyzed for both women and men. The statistical analysis indicates that there is a linear relationship between marker efficiency and fabric width (sig <0.05). The regression analysis (p-value) between dependent variables and predictor variables (body types and fabric width) is also statistically significant. Also, the result implies that markers are more productive with larger fabric widths in all styles in both genders.
Isomorphisms from the Space of Multilinear Operators

Published: July 2019

Summary
In this article, using the Mizar system [5], [2], the isomorphisms from the space of multilinear operators are discussed. In the first chapter, two isomorphisms are formalized. The former isomorphism shows the correspondence between the space of multilinear operators and the space of bilinear operators.
The latter shows the correspondence between the space of multilinear operators and the space of the composition of linear operators. In the last chapter, the above isomorphisms are extended to isometric mappings between the normed spaces. We referred to [6], [11], [9], [3], [10] in this formalization.

Published: July 2019

Abstract
Eurasian steppes have an essential role in conserving biodiversity, but due to the huge habitat loss in the past centuries they are often preserved only in small refuges. Among such refuges are the ancient steppic burial mounds (the so called ‘kurgans’) which have a high cultural and historical importance and are also essential sites of nature conservation. Despite their high number (approximately half million) and conservational importance there is a huge lack of knowledge on the locality and conservational state of the kurgans in most regions of Eurasia. To fill this knowledge gap, we built a public database which allows to record and query basic information on their cultural values and factors (such as land cover type, threatening factors, cover of woody species) that might serve as a basis for their effective conservation. The database provides a transparent, public and easy-to-use source for conservation managers and landscape planners focussed on grassland conservation. In addition, it also provides background information for other associate disciplines and public agencies dealing with the protection of cultural heritage.

Published: July 2019

Abstract

Research purpose. The development of financial technology sector (fintech) poses a challenge for traditional financial institutions. Therefore, it is important to analyze not only how financial technologies can change, but also how the fintech sector affects banks and their profitability. The aim of the paper is to analyze the possibilities for the development of financial technology sector and quantitatively evaluate its impact on the banking sector’s profitability in Lithuania.

Design / Methodology / Approach. After the analysis of academic literature and statistical data, the authors used expert evaluation method in order to identify development opportunities of fintech in Lithuania and correlation-regression analysis was applied to evaluate the impact of fintech on the profitability of the Lithuanian banking sector.

Findings. According to the results of expert assessment research, Lithuania possesses favorable conditions for fintech enterprises to enter the Lithuanian finance market; it is expected that this sector will continue to rapidly expand mostly in payments and banking business models. Correlation-regression analysis showed that fintech indicators has an effect on the banking sector’s profitability but the effect in not very significant. The significance of the connection is lower because banking sector adapts technologies and is influenced by fintech from inside and outside the environment.

Originality / Value / Practical implications. The fintech sector in Lithuania is still new and so far very little researched. The outcomes of this research have expanded the scope of research of the Lithuanian fintech sector. The obtained results would be useful and relevant to (i) the government sector to manage risks and ensure stability in the financial sector; (ii) financial sector entities to monitor possible developments and prepare them accordingly; and (iii) banking sector to analyze the impact of technology and fintech entities on them and take strategic decisions in this regard.
The Impact of Acquisition on Stock Value in Case of Warsaw Stock Exchange
Authors: Kaczmarczyk Wojciech 
Published: July 2019

Abstract

Research purpose: Seven of 10 companies that have won the Polish Forbes edition Merge & Acquisition 2018 Ranking are listed on Warsaw Stock Exchange. The aim of the conducted research was to test if the biggest acquisitions have an impact on stocks value and is it possible for typical investor to create extra profit by using knowledge of acquisition based on public information.

Design/Methodology/Approach: Using data from Warsaw Stock Exchange (quotations), typical measures such as rate of return, standard deviation (risk), correlation and transaction volume changes were calculated. Each of the case results obtained for the company was compared with the result for stock market indexes: WIG (Warszawski Indeks Giełdowy – main WSE index), WIG20 (WSE sub-index of the 20 largest companies), mWIG40 (WSE sub-index of 40 medium companies) and sWIG80 (WSE sub-index of 80 small companies). In addition, the outcomes were confronted with public news (from WSE Electronic System for Information Transfer).

Findings: Conducted research has shown that generally successful finalisation of acquisition results in changes of stock prices behaviour. Unfortunately, observed reactions were not the same. Acquisitions induced both increases and decreases in stock prices; there was also no rule in case of risk change. Generally, acquisitions and merges had rather good influence in banking sector (which is still concentrating), but there was no common reaction in other sectors.

Originality/Value/Practical Implications: The results will be useful for investors acting on Warsaw Stock Exchange, especially for individual investor who are not able to carry out detailed analyses. The research provides results including possible pre-effects and after-effects of making big acquisition by a large company. The negative market reactions were also shown.
