Emerging Advancement for Augmented Reality (AR) and Virtual Reality (VR) in Dentistry

The skill of visual reality has matured, and VR and AR are increasingly being used in educational and surgical settings. The development of virtual reality technologies allows users to mix medical knowledge, medical data, and graphical data. It can provide more precise information, allowing users to increase their safety and reduce their risk. Virtual reality (VR) or augmented reality (AR) simulators that provide direct feedback and objective evaluation could be a useful tool in dental education in the future. Not only has it been applied to education, but it has also been created in therapeutic therapy. The authors believe that in the future VR and AR training and teaching will be extended and used in every aspect of dentistry, enabling students to develop their abilities on their own. In comparison to augmented reality, virtual reality offers a far more immersive experience. It would establish a trusting relationship between patients and doctors based on the experience of the dentists and the use of different hardware and software.

Approbation of the methodology for determining the time of passenger movement on the inner-city and suburban route

Presents the results of testing the methodology for determining the passenger's travel time according to the "door-to-door" scheme on intra-city and suburban routes using hovercrafts. The introduction presents the results of the analysis of a number of research works of domestic and foreign scientists in the field of passenger transportation by hovercraft. The analysis showed that studies of passenger travel taking into account such factors as distance and time according to the "door-to-door" scheme on intra-city and suburban routes in riverine regions by buses and hovercraft do not occur, which means that the chosen research topic is relevant. The methods section summarizes the basics of calculations and initial data for testing the methodology for determining the time spent by passengers on a trip using a hovercraft. The results section provides graphical data as a result of testing the methodology. The opinion of the authors of the article on the use of alternative travel options by a passenger on intra-city and suburban routes by road and (or) river transport is put up for discussion. In the final part of the article, it is determined that this method of determining the travel time of a passenger on intra-city, and in comparison, may be of interest both for passengers and transport organizations.

Pre-Algebra Students’ Performance Locating and Interpreting Data in Graphs and Maps

Introduction Developing graphicacy skills is important for students with visual impairments if they are to succeed in science, technology, engineering, and mathematics (STEM) content. Teachers of students with visual impairments report that they lack resources to use in teaching students graphicacy skills. Methods Forty-one students with visual impairments in grades 5–10 completed a pretest, intervention, and posttest designed to evaluate their skills locating and interpreting graphical data. Videos of the pre- and posttests were scored using a researcher developed instrument. Results Following intervention, there was a significant difference in students’ ability to use descriptors and mathematical terms when exploring graphs and a map. Students answered significantly more questions correctly from pre- to posttest. Discussion Students who receive direct instruction in how to locate and interpret data in graphs and maps can improve their level of independence in STEM classes. Use of an intervention that targets the development of graphicacy skills has been found to be effective. Implications for practitioners More research is needed to determine effective hand strategies students should use when exploring different types of graphics.

MIGRATION PROCESSES TO RURAL AREAS IN POLISH METROPOLISES

The research problem addressed in this paper includes the progress of suburbanization in selected Polish metropolises. The following core question was formulated: when did today’s suburbanization processes start, and what are the migration trends and targets of the population living at the dividing line between urban and suburban limits in Polish metropolises. Defined as such, the study field enabled formulating the objective of this research, which is to present the formation of new suburbanization processes in the largest metropolises in Poland. Considering the research problem and the defined objective, the authors analyzed the differences in demographic changes across the territory, and put these findings in the context of suburbanization and its stages. This allowed to determine the dynamics and targets of migration in the metropolises surveyed. Also, the changes were compared between the units covered, providing a basis for further considerations on suburbanization and for concluding whether these processes are cyclical in nature. The analyses relied on descriptive statistics methods and on graphical data presentation methods. The selected metropolises were delimited using QGIS Desktop 2.4.0 and adequate geometry (centroid) and geoprocessing (buffer) tools. This paper relies on source data in the form of shapefile vector layers presenting the boundaries of the administrative units considered (http://www.gugik.gov.pl/pzgik). Source materials included public statistical data and program documents developed at regional and sub-regional level. The study period is 1995-2018. In geographic terms, the study focuses on the selected metropolises of Poznań, Warsaw, Łódź, Wrocław, Krakow, Gdansk and Szczecin.

Graphical Data Analysis

Limitations in statistical significance testing are an issue of ongoing debate in many academic disciplines. Moving away from a reliance on their use in quantitative research is seen as an important step towards improving the quality of such research. One area that can help here is graphical data analysis, both as an exploratory and explanatory tool. This paper presents an overview of graphical techniques for quantitative data analysis. After outlining the rationale for the use of graphical data analysis, consideration of the appropriate types of graphs to use is provided. A number of useful graphs, created using the R statistical package, are introduced, along with a link to the full code to reproduce the examples. Suggestions are presented for how graphical techniques can help with both the exploration and conformation stages in research. 統計的有意差検定の限界は、多くの学術分野で継続的に議論されている問題である。量的研究における統計的有意差検定への使用依存から脱却することは、研究の質を向上させるための重要なステップであると考えられる。ここで役立つのが、探索的・説明的なツールとしてのグラフデータ分析である。本稿は、定量的なデータ分析のためのグラフ技術の概要を説明する。グラフィカルなデータ分析を使用する理由を説明した後、使用するグラフの適切な種類について検討する。R統計パッケージを用いて作成された便利なグラフの数々を紹介し、例題を再現するための完全なコードへのリンクも掲載する。本稿は、研究における探索と適合の両方の段階で、グラフ技術がどのように役立つかを提案するものである。

Crossbreed impact of double-diffusivity convection on peristaltic pumping of magneto Sisko nanofluids in non-uniform inclined channel: A bio-nanoengineering model

The consequences of double-diffusivity convection on the peristaltic transport of Sisko nanofluids in the non-uniform inclined channel and induced magnetic field are discussed in this article. The mathematical modeling of Sisko nanofluids with induced magnetic field and double-diffusivity convection is given. To simplify PDEs that are highly nonlinear in nature, the low but finite Reynolds number, and long wavelength estimation are used. The Numerical solution is calculated for the non-linear PDEs. The exact solution of concentration, temperature and nanoparticle are obtained. The effect of various physical parameters of flow quantities is shown in numerical and graphical data. The outcomes show that as the thermophoresis and Dufour parameters are raised, the profiles of temperature, concentration, and nanoparticle fraction all significantly increase.
