An Analysis of Reports by The Illustrated London News (ILN) and The Graphic against Social Activities in Malaya in the 19th Century

Unlike in the West, the emergence of visual printing and printing press in Malaya was comparatively lagged behind. Publication and printing reached the Malayan shore through the Straits Settlements after the first publication was brought in and introduced by A. B. Bone in 1806. Since then, various visual reports regarding Malaya made their way into the well-known newspapers in Britain, The Illustrated London News (ILN) and The Graphic. Social activities in Malaya became part of the main visual report in these newspapers. Nonetheless, it was found that these newspapers were not objective in reporting the news on social activities in Malaya. In lieu of this, the current research attempted to find out the extent of the action of ILN and The Graphic in manipulating visual news report about the social activities in Malaya in the 19th century. In addition, this research also aimed to find out how far the ideas and thoughts of both newspapers in describing the news reports related to social activities in Malaya in the 19th century. This research focuses on the 19th century, within the specified period, of which the two respective presses released many visual news reports regarding social activities in Malaya. The qualitative method and visual approach were chosen as the research itself was conducted in London, especially at the National Art Library, situated in the Victoria and Albert Museum. In Malaysia, materials and resources were obtained from the Malaysian National Archive, National Museum, National Library, and libraries at higher learning institutions.

MURAL BUDAYA DI KAWASAN DESA WISATA AIR TERJUN GREMBENGAN, DESA BONGAN, KABUPATEN TABANAN

Mural is well known as a wall design. The community service was carried out by the IDB Bali Lecturer Team in Bongan village, Tabanan. The community service program in the form of community service activities that will be carried out is in the form of mural activities located in the area of the road to Grembengan Waterfall Tourism, Bongan Tabanan Village. The walls to be mural have a length of 40 meters with a height of 2.8 meters and 140.8 meters for the total area. There were moral and social messages in people's lives with a visual approach in the form of displaying local Balinese culture, and containing messages or social criticism, one of which is related to the pandemic. The mural image shows a boy wearing a mask sweeping the yard and the others washing their hands. It is hoped that this image can be informative enough for visitors so that visitors can get used to living clean and healthy. The mural is done using the conventional method, by painting it, so as to bring out the aesthetic side of the mural that is more expressive. This is inseparable from the ability and the results of the paint scratches that are displayed.

Multicriteria Visual Approach to the Analysis of Water Quality—A Case Study of the Tisa River Basin in Serbia

The aim of this research is to provide the assessment of water quality with a wider scheme of interrelations between the water quality parameters and locations using a reliable visual approach of multicriteria PROMETHEE and GAIA methods. The case study of one of the largest and regionally most important catchment areas on the territory of the Republic of Serbia—the Tisa River Basin—was therein used. The analysis of water quality included scenarios for warm (summer), cold (winter), and average annual period. A partial and complete ranking of locations according to the quality of water was performed by applying the PROMETHEE method and expanded afterward by GAIA method analysis to point out critical locations with endangered water quality (M6, M4, and M11). Identified locations were then investigated in more detail using spider web graphs that revealed water quality variables of concern (PO4-P and N) and indicated the causes of its occurrence. The obtained results are in accordance with the results of physical and chemical tests that are regularly conducted by the official government agencies for environmental protection and the reports that are presented to the public. The presented approach can easily be applied to any water body to point out both the locations with reduced water quality and the specific parameters (causes) that affect the reduction of water quality at these locations, thereby enhancing and strengthening usual water quality assessments as well as water resources management in general.

A Mathematical, Graphical and Visual Approach to Granular Synthesis Composition

We show a method for Granular Synthesis Composition based on a mathematical modeling for the musical gesture. Each gesture is drawn as a curve generated from a particular mathematical model (or function) and coded as a MATLAB script. The gestures can be deterministic through defining mathematical time functions, hand free drawn, or even randomly generated. This parametric information of gestures is interpreted through OSC messages by a granular synthesizer (Granular Streamer). The musical composition is then realized with the models (scripts) written in MATLAB and exported to a graphical score (Granular Score). The method is amenable to allow statistical analysis of the granular sound streams and the final music composition. We also offer a way to create granular streams based on correlated pair of grains parameters.

Map Evaluation under COVID-19 restrictions: A new visual approach based on think aloud interviews

With the beginning of the COVID-19 pandemic, the execution of eye-tracking user studies in indoor environments was no longer possible, and remote and contactless substitutes are needed. With this paper, we want to introduce an alternative method to eye tracking, completely feasible under COVID-19 restrictions. Our main technique are think aloud interviews, where participants constantly verbalize their thoughts as they move through a test. We record the screen and the mouse movements during the interviews, and analyse both the statements and the mouse positions afterwards. With this information, we can encode the approximate map position of the user’s attention for each second of the interview. This allows us to use the same visual methods as for eye-tracking studies, like attention maps or trajectory maps. We implement our method conducting a user study with 21 participants to identify user behaviour while solving high-level interpretation tasks, and with the results of this study, we can show that or new method provides a useful substitute for eye-tracking user studies.

Visual aspect-oriented modeling of explorable extended reality environments

The availability of various extended reality (XR) systems for tracking users’ and objects’ behavior opens new opportunities for analyzing users’ and objects’ interactions and autonomous actions. Such analysis can be especially useful and attainable to domain experts when it is based on domain knowledge related to a particular application, liberating the analysts from going into technical details of 3D content. Analysis of XR users’ and objects’ behavior can provide knowledge about the users’ experience, interests and preferences, as well as objects’ features, which may be valuable in various domains, e.g., training, design and marketing. However, the available methods and tools for building XR focus on 3D modeling and programming rather than knowledge representation, making them unsuitable for domain-oriented analysis. In this paper, a new visual approach to modeling explorable XR environments is proposed. It is based on a semantic representation of aspects, which extend the primary code of XR environments to register their behavior in a form explorable with reasoning and queries, appropriate for high-level analysis in arbitrary domains. It permits domain experts to comprehend and analyze what happened in an XR environment regarding users’ and objects’ actions and interactions. The approach has been implemented as an extension to MS Visual Studio and demonstrated in an explorable immersive service guide for household appliances. The evaluation results show that the approach enables efficient development of explorable XR and may be useful for people with limited technical skills.

A Visual Approach for Solving Problems with Fractions

This article discusses the importance of visual models in problem solving, in the scope of rational numbers. We seek to highlight the potential of this approach, as a structuring theme in the mathematical development of students in elementary education and the connections it allows to establish. In order for students to be mathematically competent and creative, they must be able not only to solve traditional computational problems but also to use models/visual representations when solving all types of mathematical problems, including those in which the visual component is not evident. We developed a qualitative study based on a didactical experience involving 14 future teachers who were attending a Didactics of Mathematics unit course that included a module about problem solving with emphasizes in visual approaches. The main purpose of the study was to identify the strategies used by the future teachers when solving problems with multiple solutions, before and after that module. Data was collected through observation and the written productions of the participants. It was possible to conclude that they tended to privilege analytical approaches before the intervention and, after the teaching experience, they started to value visual approaches, which generated an increase of the productions involving this type of solutions.
