Abstract
The aim of this study was to stress the importance of investigating the properties
of preservation enclosure materials in order to identify the ones that
are able to protect their contents more efficiently. Since not all information
on materials is covered by international standards and technical specifications,
nine paper-based materials used for making preservation enclosures
(file folders, passepartouts, boxes etc.) were investigated. A selective analysis
of the materials' properties was carried out to determine smoothness, water
absorptiveness, water wettability, water vapor permeability, tensile strength,
folding endurance, bursting strength, puncture strength, as well as loss of
bursting strength caused by dry heat and 100% RH. Results obtained from
measuring smoothness, water absorptiveness, water wettability and water
vapor transmission rate indicate that a material outside of ISO 16245:2009
grammage requirements for making file covers can exhibit more desirable
properties than the one that meets multiple standards for storage and
preservation. Additionally, results showed that bursting strength of enclosure
materials was significantly affected by both extreme microclimate conditions.
However, 100% RH had affected bursting strength of the investigated
materials more than dry heat. The presented procedure proved to be a useful
indicator of materials’ properties within the context of heritage collections
preservation and storage.

Abstract
In the 21st Century, the common features of the developing digital technology
are compressed information, accelerated information management,
big data, multiple interaction, personalization and uninterrupted access and
convergence. These features are seen as factors that accelerate access to
information, reduce some communication and cost expenses economically,
speed up sales and marketing, provide visibility to institutions, and increase
ideas and sharing. With the effects of digital technology Contemporary art
museums and galleries have experienced digitalization processes in order to
maintain their existence and achieve their goals. Digitalization is not limited
to being a technical application, but it is a process that transforms contemporary
art institutions as a whole, especially in communication, institutionalism,
branding, marketing, finance and sustainability. Therefore, digital
technology requires to be available to institutions. Being a contemporary
art institution requires being intellectually and technologically renewed in
institutional, managerial and communicative terms. The mission and sustainability
of art and art institutions should be ensured in harmony with technology.
Therefore, new business models have been required in the digitalization
processes in art institutions and the need for changing business models will
increase as technology develops. Purpose of the study: To identify the new
business models of contemporary art museums and galleries, and in parallel,
the features they need in human resources, and to raise awareness on this
issue. In this study, the hybrid structure of new business models needed in
contemporary art institutions has been revealed as a whole. In the study, it
has been revealed based on the examples and the viewpoints of authorized
persons that, managerial digital strategies in contemporary art museums
and galleries should contain the distinction specific to art. The main result
that emerged from the interviews is the hybrid structures of the new business
models needed by contemporary art museums and galleries in the digital
age, blended with digital technology and the knowledge of art management.

Abstract
Creating 3D computer-generated surfaces has long been a difficult
challenge in computer graphics, particularly when portraying massive
landscapes with extremely detailed surfaces in real-time. Despite significant
advances in computer vision in recent years, there is still a great demand
for improved realism and the capacity to edit computer-generated 3D
surfaces in real-time. We propose three scalable and faster algorithms
for creating extended, beveled, and chamfered patterns using only two
textures and a simple shape box. The proposed techniques produce
visually pleasing results in real-time while retaining optimal rendering
performance and without increasing the mesh density of the shape box.

4. Influence of hue and saturation on colour-shape association

Abstract
A century ago, Wassily Kandinsky postulated that there was a strong and
biunivocal correlation between elementary geometric figures and primary
colours, respectively the most suitable associations were blue circle, yellow
triangle, and red square. Most researchers did not find evidence in support
of Kandinsky's combination, but rather in support of another combination:
red circle, yellow triangle, and blue square (later called the “dissident”
combination). And it was also found that the correlation was not strong,
but rather medium. Until now, research has not focused separately on the
influence of hue (at maximum saturation) on the appropriateness perception
of shape-colour association, nor on the influence of saturation on the same
perception. In view of this, two experiments were organized on samples of
546 and 461 participants that were all unaware of Kandinsky's experiment.
The first experiment confirmed that hue influences the appropriateness
perception of coloured figures, but also that, surprisingly, the shape-colour
association was not biunivocal. The participants appreciated that the most
appropriate associations were the red circle, the red triangle, and the
blue square. However, the means of the appropriateness marks were not
high. The second experiment proved that the appropriateness perception
of coloured figures was directly influenced by colour saturation, and the
correlation was strong (the correlation coefficient being between 0.71 and
0.94). Obviously, the experiments did not validate Kandinsky's theory.
