Chapter 12. Approximation Theory: Polynomials and Chebfun

Twenty years later began the stage of my career in which I have really been using approximations. In fact, I have probably turned into the leading instance of a mathematician who is applying approximation theory to get things done. I am speaking of the relatively classical, one-variable part of the subject. The multivariate side is being applied by many people these days in connection with deep learning, neural networks, and data science.
Research on PIV algorithm for reconstruction of velocity field of fluid with high Reynolds number

For the problems of distortion and rotation in the image matching of turbulent motion with high Reynolds number, according to the nature of affine transformation, using log-polar coordinate transformation, the matching of turbulent particle images is achieved by performing correlation calculations on the image line by line and developed a matching algorithm (Turbulent Particle Image Matching, abbreviation: TPIM) for particle image pairs with affine transformation and rigid body transformation: by moving the interpretation window, the algorithm is no longer restricted by displacements of particles; by setting the affine lines according to the angle of the image in the log-polar coordinate system and using the affine line as the matching unit, the decoupling of different transformation factors is realized; according to the characteristic of non-uniform sampling in log-polar coordinate transformation, based on the principle of not losing image information, by reasonably setting the image mask and the rate of sampling, establishing the image pyramid and the relative coordinate system, the algorithm complexity is reduced to about 15% of the original. The experimental results of various types of particle images show that the matching accuracy of the TPIM algorithm can reach more than 99%.

A Study Development of Program for Enhancement of Special Teachers’ Competency to Use Educational Drama in Class: Focusing on the Department of Korean Language Class

The purpose of this study is to development a program for enhancing special teachers’ competency to use educational drama in Korean Language class; the design is based on basic processes including analysis, design, development, execution, and evaluation of the ADDIE model. In the analysis phase, factors of competency to use educational drama in Korean Language class were derived through a review of previous studies and literature; accordingly, the educational purpose and goal of the program were established. In addition, in order to reflect the needs of incumbent teachers, in-depth interviews were conducted with six incumbent special education teachers; this was then followed by a questionnaire survey of 109 incumbent special education teachers. By reflecting the needs of special education teachers collected through in the design phase, the educational purpose and goal of a program for enhancing competency to utilize educational drama in Korean Language class was clearly implemented based on the theoretical basis. In the development phase, the contents of education, teaching and learning methods, educational evaluation, and operation methods were decided; from this, a program plan was derived. The program plan was revised and supplemented twice through content validity review by 10 experts; based on this, a program plan for each two types of session number was developed. In the implementation phase, based on the program plan for each session numbers, programs of 15 sessions with 30 hours were administered for five special education teachers currently working for schools. In the evaluation phase, along with the changes that occurred after the implementation of the program plan, the self-evaluation was conducted during the process. This study confirmed the necessity of Korean Language classes using educational drama in the field of special education. Furthermore, based on this, this study presented a program model to comprehensively enhance the teaching competency of special education teachers.
Effects of Data-Based Individualized(DBI) Hangul Phonics Instruction on Reading Achievement of Elementary School Students With Intellectual Disabilities

The purpose of this study was to examine the effects of Data-Based Individualized(DBI) Hangul phonics instruction has on reading achievement(Hangul reading, alphabet knowledge and decoding). Three elementary students with intellectual disabilities in grades 3 to 5 participated in this study furthermore a multi-probe design across participants was used to investigate the effects of both the intervention and maintenance. A researcher provided a DBI hangul phonics program to the student participants 3 times per week, 30 minutes per day a total of 20 to 38 sessions was delivered to the students. Researcher-developed hangul CBM measures were used consistently across baseline, intervention, and maintenance phases in addition standardized tests on alphabet knowledge and decoding were used before and after the intervention. The results of this study showed that the level of hangul reading of the students was improved at the intervention phase compared to its level at the baseline phase, and the effects were maintained after the phase was completed. In addition, post-test scores on alphabet knowledge and decoding were higher than the pre-test scores. However, the degree of improvement of decoding was varied across individual students. These results imply the positive effects of using DBI hangul phonics instruction to enhance reading achievement of elementary school students with intellectual disabilities. Based on the findings-discussion, limitations and suggestions for future research were suggested.
A Study on the Readability of American English Textbooks and Korean English Textbooks Comparing Syntactic Complexity and Conjunction Frequency in Sentence Structures

The purpose of this study is to investigate the differences in readability as defined by Kim (2002) between textbooks used in grades 3~6 in American textbooks and 9~11 in Korean English textbooks. Based on Park (2015)’s observations on conjunction length and readability, has been hypothesized that the number of conjunctions used in complex sentences differentiates readability between language proficiency levels. Using 17 textbook samples from three widely used American textbook publishers ranging from grades 3~6 and 39 samples from twelve official Korean English textbooks ranging from grades 9~11—for a total of over 200,000 words—the study used the L2 Syntactic Complexity Analyzer (L2SCA), the Flesch-Kincaid Grade Level (FKGL), and the Flesch Reading Ease (FRE) scale, finding that the American textbooks had far more frequent instances of conjunctions used in between complex sentences, leading to decreased readability—as supported by Lee (2010), who found the readability of Korean English textbooks to be higher than corresponding American English textbooks. The study was limited in the scope of its sampled data and further studies should include datasets from more publishers and sources in order to corroborate the present findings.
The Use of Smartphones and Tablets for Teaching Biology at a Distance: A Comparison between Rural and Urban Schools

Smartphones and tablets (SPT) have become an integral part of daily life, and their added value for biology education was seriously tested during the COVID -19 pandemic in distance education. We collected data from 355 elementary-aged children attending 6 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> to 9 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> grade; 30% of the participants were from rural schools and 70% from urban schools. Results show that most children, 75.7%, used SPT very frequently to search for information on the World Wide Web and 65.9% used SPT frequently to participate in distance learning (videoconferencing). Very rarely, if ever, was SPT used to conduct experiments, virtual field trips, or hands-on work in virtual laboratories. PCA analysis revealed 2 components. The first component explained the non-use of SPT for hands-on work (33.6%, Cronbach’s alpha =0.85) and the second component explained the use of SPT for communication and collaboration (28.8%, Cronbach’s alpha =0.77). We were also interested in whether the environment of the school (rural or urban) influenced the use of SPT. There is no statistically significant difference in access to wearable smart technology between urban and rural students.
A Lightweight and Robust Dynamic Authentication System for Smarthome

The advent of smarthomes improves the comfort in the homes. In this work, we are interested in automatic opening of gate at the arrival of legitimate vehicles in order to avoid that the occupants have to wait at the door. Indeed, due to the rise of insecurity in our cities, cases of aggressions in front of the doors are regularly reported. Also, the noise pollution necessary to be noticed at the door disturb the neighborhood. The major challenge of the gate automation is security. Most of the proposed solutions do not sufficiently take into account the robustness of the vehicle authentication mechanisms. We propose a security enhancement for vehicle access control with a sensor node on board at a gate that also has a sensor node. Our mutual authentication protocol between the two sensor nodes takes into account the resource limitations of the used objects. It is based on dynamic one-time passwords. We exploit random number generation and processing functions, Elliptic Curve Diffie Hellman Ephemeral (ECDHE) key exchange principle and HMAC-SHA256 hash function. The lightweight system with only one message exchanged in total offers a very low reaction time for the gate. Its dynamic nature allows it to resist to cryptanalysis and spooking attacks.
Task-Based Workplace English: An Adaptive Multimodal Tutoring System

Personalized language learning (PLL) is central to educational and industrial communities worldwide. In our ongoing work, we developed a new multimodal intelligent tutoring system (ITS) with dynamic adaptation for a task-based workplace English language learning. Our work focuses on helping users improve their speaking and behavioral communication skills in the context of a fictional workplace environment while interacting with character-avatars(e.g., project supervisors and fellow team members). The system captures the users’ multimodal interaction footprint, including clickstream, audio, and video data. Our learner model measures user skill mastery based on users’ response data and provides dynamic adaption on item difficulty.
Investigating the Corporate Governance and Sustainability Relationship: A Bibliometric Analysis Using Keyword-Ensemble Community Detection

Sustainability is a business strategy combining economic, social, and environmental issues. This paper examines the corporate governance and sustainability literature. So we consider a new bibliometric database focusing on the network of keywords appearing in the literature. The quantitative approach is also new: we combine the information from different community detection algorithms to find the most important results and relationships in the literature. The final results show that the literature on corporate governance and sustainability raises an essential strategic question: for long-term sustainability if there needs to be a strong link between stakeholders and corporate social responsibility (CSR). So, considering a company’s actions’ social, economic, and environmental effects can help figure out how much corporate responsibility is needed. Also, companies that consider CSR and sustainability in their businesses find it easier to keep long-term relationships with customers, employees, and other stakeholders, which can be considered vital. Last, a strategic view of corporate governance should emphasize the importance of intellectual capital and the Triple-Bottom-Line approach to sustainable growth in a strategic view of corporate governance. In this sense, a more wholesome view of value creation aims to provide companies with better financial results while also serving society’s environment and social well-being. By addressing these issues, governments and other groups can make the business world more sustainable and responsible.
Motor Boats in the Technology of HDPE with RIB Type Construction

Aim: In 2022, on the lakes Zegrzynskie and the Orzysz, there were carried out tests of a motor boat with a hull made in HDPE technology and a construction similar to a hybrid boat (rigid-inflatable boat, RIB). The aim of the tests was to examine the operational capabilities of the SRB53 motor boats and obtain preliminary information on the configuration of the equipment. Introduction: High performance motor boats should constitute standard equipment of lifeguards. There are motor boats on the market using high density polyethylene (HDPE) for the construction of their hulls. Methodology: The survey involved 57 people, experts, representatives of public administration, NATO soldiers, police, and rescue services, as well as enterprises and non-governmental entities operating in the field of water rescue. The working hypothesis was assumed that probably motor boats as a combination of HDPE technology with a hybrid boat design could match the operational rib boats and have an advantage in terms of durability and resistance to hull damage. A diagnostic survey was used on a small sample with research techniques, i.e., observation, interview, and test, as well as research tools in the form of an observation sheet. The research was prepared, carried out and closed in the following order: development of the research procedure, collection of research material, development of results, theoretical analysis of the obtained material and derivation of conclusions. The scope of the boat study included going away and nailing to the quay, the boat’s behaviours when making turns and abrupt turns in both directions at different speeds, and the hull durability test. Results: The test results and opinions were positive, many advantages of the hull of the tested boat were indicated, with one negative parameter – a higher weight compared to traditional rescue boats. The working hypothesis was proved: motor boats in HDPE technology with a hybrid boat design are equal in terms of operation to RIB boats and are more durable and resistant to impacts. Innovative HDPE technology is useful for boat production. Due to the purpose, different configuration and equipment of the boat should be assumed. Keywords: motor boats, water rescue, polyethylene, technology, innovation
Design of Gamification of Flood Early Warning Actions Using the "Cikeas – Cileungsi Overflow" Game in the KP2C Community

The role of the early warning system by the KP2C Community in providing information on flood disasters that often occur in the Cileungsi – Cikeas watershed really helps the community in reducing the impact of the unavoidable flood disaster. The creation of the game “Cikeas – Cileungsi Overflow” aims to introduce knowledge about actions related to flood early warning to the wider community more effectively and fun. By using the gamification method, real activities carried out by KP2C such as interacting with residents through social media, monitoring the condition of upstream rivers, and providing disaster warnings, can be displayed in a simpler form into an educational game. The process of creating a game is carried out by conducting research on various types of KP2C activities in becoming an early warning instrument and then converting the data into a game mechanic. Through the results of game testing, 93.4% of respondents said the gameplay displayed in the game "Cikeas – Cileungsi Overflow'' was quite interesting and 90% of respondents stated that their understanding of the concept of a flood early warning system had been conveyed well. There are still several aspects that need to be developed in the future from the "Cikeas Cileungsi Overflow '' game, especially the leaderboard mechanism which still has problems and continued development to the Android platform
Deep Learning in Colorectal Cancer Classification: A Scoping Review

Colorectal cancer (CRC) is one of the most common cancers worldwide, and its diagnosis and classification remain challenging for pathologists and imaging specialists. The use of artificial intelligence (AI) technology, specifically deep learning, has emerged as a potential solution to improve the accuracy and speed of classification while maintaining the quality of care. In this scoping review, we aimed to explore the utilization of deep learning for the classification of different types of colorectal cancer. We searched five databases and selected 45 studies that met our inclusion criteria. Our results show that deep learning models have been used to classify colorectal cancer using various types of data, with histopathology and endoscopy images being the most common. The majority of studies used CNN as their classification model. Our findings provide an overview of the current state of research on deep learning in the classification of colorectal cancer.
Prototype Expert System for Gout Diagnosis on an Outpatient Basis

Gout is a systemic disease that is caused by the deposition of monosodium urate crystals in various tissues which leads to inflammation in them. This disease is often misdiagnosed. It leads to the lack of adequate medical care and development of serious complications, such as urate nephropathy and disability. The current situation can be improved by optimizing the medical care provided to patients, which requires searching for new strategies in terms of diagnosis. One of these strategies is the development of an expert system for providing information assistance to medical specialists which was a purpose of this study. The developed prototype expert system for gout diagnosis has knowledge base including 1144 medical concepts and 5 640 522 links, intelligent knowledge base editor and software which helps practitioner make the final decision. It has sensitivity of 91,3% [95% CI, 89,1%-93,1%], specificity of 85,4% [95% CI, 82,9%-87,6%] and AUROC 0,954 [95% CI, 0,944-0,963].
Interface design for 360°real scenes-based virtual reality system with pedaling devices

As the elderly get older, they often have problems such as a gradual decline in physical function, it may even lead to the risk of lower limb disability if they stay at home or sit for a long time without regular exercise. In order to prevent the lower limbs of the elderly from being disabled, stepping devices are often used as a kind of exercise, which can not only control the amount of exercise but also improve cardiopulmonary function, and can also reduce the risk of injury during training. However, the elderly cannot maintain regular exercise due to insufficient training motivation.To understand and explore the motivation of 360° real scenes-based virtual reality for the elderly to use the lower limb pedaling device, we created VBike, a system that combines 360° real scenes-based virtual reality based on a pedaling device and a heart rate watch connected with Bluetooth. From this study, we can understand the design steps and implementation methods of the combination of 360° real scenes-based virtual reality with pedaling devices and confirm that 360° real scenes video will affect the motivation of the elderly to use the pedaling device. In the future, this study suggests adding the design of guide signs and audio-visual guides to help the elderly see and explore more in-depth 360° real scenes-based virtual reality and increase the experience of pedaling by the elderly.
Innovative dining experience realized by developing naked-vision floating projection

With the advent of the COVID-19 post-epidemic era, human life has gradually transformed into a new form: less contact, avoiding dining together and reducing open shared spaces. The traditional lifestyle of human interaction, cultural participation, and sharing of emotions has changed, and this has become a new issue that needs to be resolved. This project aims to develop a naked-vision multi-level optical projection system as a cultural carrier and construct a new catering cultural field. We projected beautiful images of solar terms, poetry, and natural scenery on the dining table. The virtual animation mixed with the tableware in three-dimensional space to construct an immersive field of naked mixed reality. Innovative technical indicators are three-dimensional floating and touchable projection images. A multi-mirror staggered array optical element combined with a directional light projection system will achieve floating projection for engineering technology. The virtual image is projected into the physical space and completes the effect that the virtual image is "touchable and unavailable" (that is, it will pass through the virtual image when touched by the hand). To achieve the function of the interaction between floating images and people, we will use hand posture information to control the interface, define the floating image's imaging position through leap motion, match the operation behavior's position, and trigger the pre-designed animation content. This paper focuses on the display issue, and we will present another paper on the interactive issue.
