Accessibility of Software/Hardware
Authors: Chandel Meenu , Sood Manu
Published: March 2023

The phenomenal growth in Information and Communication Technology (ICT) is rapid and is responsible for changing disruptively the way various day-to-day tasks were being performed earlier. A plethora of user categories has benefitted immensely from this upward growth. It is also providing society with a multitude of entertainment options. The support of user-friendly software platforms for various ICT applications and tools is crucial in all these activities. Unfortunately, in the past, the designers of many software and hardware systems have not appropriately considered the Persons with Disability (PwD) as the active co-fellows of this journey and are being left behind in most of such applications of ICT. Thus, this significant part of the world population often seems to be neglected. Accessibility to every user with specific reference here to the ICT has always been a very important issue. What may be easily accessible to a set of persons may not be completely or partially accessible to another set of persons with disabilities. In this chapter, we discuss various types of disabilities along with the accessibility of hardware and software. Further, we highlight the concept of web accessibility and ICT accessibility for PwDs.
Technologies for Hearing Impaired People Using Indian Sign Language Synthetic Animations
Authors: Kumar Rakesh , Goyal Lalit , Goyal Vishal
Published: March 2023

This chapter discusses various technologies developed for deaf people using Indian sign language synthetic animations. An automatic translation system for English Text to Indian Sign Language synthetic animations in the real domain has been developed, which consists of a parsing module that parses the input English sentenceto- phrase structure grammar representation on which Indian sign language grammar rules are applied to reorder the words of the English sentence. The elimination module eliminates the unwanted words from the reordered sentence. Lemmatization is applied to convert the words into the root form. The words (or their synonym in case the word is not available in the database) in the sentence are replaced by their HamNoSys code. In case the word or its synonym is not present in the lexicon, the HamNoSys code will be taken for each alphabet of the word. The HamNoSys code is converted into SiGML tags, which are sent to the animation module, which converts the SiGML tags into synthetic Animation using an avatar.
Prototypes for announcement systems for deaf people at railway stations, airports and bus stands have been developed. The announcements are categorized and sent to the system in written form. These announcements are dynamically converted to ISL sentences and then animated using HamNoSys and SiGML tags.
These translation and announcements systems are the only systems in the country that use continuous synthetic animations of the words in the sentence. Existing systems are limited to the conversion of words and predefined sentences into Indian sign language, whereas our conversion system converts English sentences into Indian sign language in the real domain.

Authors: Goldena Nancy Jasmine , Thangapriya
Published: March 2023

People with impairments frequently struggle to carry out daily activities alone or even with assistance. They encounter obstacles in the environment, movement, interaction, access to writings, personal health maintenance, handling medical issues and behavioral equality. One of the subjects that have received a lot of attention from researchers is computer-based Assistive Technology (AT). Disabled people utilize AT to tackle things previously practically impossible for them. Various forms of disabilities necessitate the use of AT, which can help people with disability to do their regular work. Therefore, these technological innovations have the power to play a substantial role in supporting huge segments of society to operate and lead a normal life. The fundamental goal of AT is to continually increase a person's ability to perform independently, hence improving their overall health. Individuals who use technological aids can lead healthy, dignified, independent and respectable lifestyles. On the whole, AT aims to enable disabled individuals to join nearly every facet of life, including at home, education and community, as well as to increase their opportunities for social interactions and meaningful employment. AT devices simply gives disabled individuals more freedom and control. The significance of AT and AT devices, current trends, approaches, limitations and some of the major challenges identified in previous assessments as well as recent research findings in the field of AT, are all effectively discussed in this chapter.
Artificial Intelligence: Future of Advance Learning
Authors: Mariappan Jasmine , Krishnan Chitra
Published: March 2023

Artificial Intelligence is not about making a robotic mind; it is all about
reshaping, and redefining the scope of learning and innovation. It is a platform for
solving problems with more intelligence and gravity. Digital learning is now an integral
part of all educational institutions in unparalleled times, which we all are a part of. In
addition to the overall interaction between teachers and students, conversational AI will
improve the classroom atmosphere and the learning experience for students. Chatbots
with artificial intelligence can be used to teach students to look as if they are in a
structured chat conversation by turning a lecture into several messages. The bot will
continually evaluate the student's level of understanding and apply the next part of the
lecture. AI and Chatbots can make their learning process more engaging and
interesting. They will help to reduce the workload for the administrative staff of
schools. This will lead to a significant increase in the education sector, recipient
interactions between teacher and student, and a climate for higher education. It not only
enhances learning but also promotes vision, resilience, and interest among students.
This chapter offers theoretical insight into why education Chatbots are the reasoning
and economic way to develop talent and success in e-learning. This chapter gives us
more insight into how conversational AI will further transform education in the future. 
Opportunities Associated with Online/Blended Teaching Learning in the Era of Digital Education
Authors: Vij Sanjna , Singh Preeti
Published: March 2023

Education is both the foundation for a thriving society and the core of what
it is to be human. COVID-19 has accelerated the adoption of information technology in
educational environments, which is a logical conclusion. As a result of this
circumstance, opportunities for the employment of digital methods in education have
arisen. Students and educational institutions were forced to convert to online learning
methods. Even before COVID-19 began, it was evident that digital education methods
would soon be used. Nonetheless, the educational environment had to be rethought as a
direct consequence of the pandemic, and we became more conscious of the importance
of technology in education. Blended learning combines offline and online education by
allowing students to interact with the instructor, study materials, and other students via
conventional classroom settings and other online platforms. Blended education has
immense potential in the long run and is destined to become the mainstream form of
teaching since it makes learning easier and more rewarding. Within the current
educational system, it is critical to give technology the attention it deserves and to
include new pedagogical techniques, such as blended learning, as the last component of
the teaching and learning process. The goal of this chapter is to discuss the value of
blended learning in the context of the pandemic, as well as the many obstacles that
come with it. This chapter aims will discuss further the importance of blended learning
for the education system’s future.

Trends in Exposure to Secondhand Smoke Among Adolescents in China From 2013-2014 to 2019: Two Repeated National Cross-sectional Surveys (Preprint)
Authors: Ma Chuanwei , Huang Yayang , Li Sixuan , Zhao Min , Zeng Xinying , Di Xinbo , Magnussen Costan G , Xi Bo , Liu Shiwei
Published: March 2023

BACKGROUND

It is well-known that secondhand smoke exposure in childhood or adolescence is positively associated with morbidity and mortality. However, less is known about the current status of and most recent trends in secondhand smoke exposure among adolescents in China.

OBJECTIVE

We aimed to assess recent changes in the prevalence of secondhand smoke exposure among adolescents in China using nationally representative data.

METHODS

We used data from 2 repeated national cross-sectional surveys conducted in 2013-2014 and 2019. A total of 155,117 students (median age 13.5 years) in 2013-2014 and 147,270 students (median age 13.1 years) in 2019 were included in this study. Sociodemographic factors and secondhand smoke exposure information were collected via a standardized questionnaire. Exposure was defined as secondhand smoke exposure ≥1 day during the past 7 days at home or in public places. Other frequencies of secondhand smoke exposure (ie, ≥3 days, ≥5 days, and every day) during the past 7 days were also assessed. The weighted prevalence of secondhand smoke exposure was calculated according to the complex sample design for surveys.

RESULTS

The prevalence of secondhand smoke exposure in any place (home or public places ≥1 day during the past 7 days) decreased from 2013-2014 (72.9%, 95% CI 71.5%-74.3%) to 2019 (63.2%, 95% CI 62%-64.5%), as did exposure at home (2013-2014: 44.4%, 95% CI 43.1%-45.7%; 2019: 34.1%, 95% CI 33.1%-35.2%) and in public places (2013-2014: 68.3%, 95% CI 66.9%-69.6%; 2019: 57.3%, 95% CI 56%-58.6%). The prevalence of secondhand smoke exposure decreased with increased gross domestic product per capita in each of the 2 survey years irrespective of exposure frequency or location. The prevalence of exposure at other frequencies (ie, ≥3 days, ≥5 days, or every day during the past 7 days) also decreased in any place, at home, and in public places. Secondhand smoke exposure was associated with higher school grade level (ninth vs seventh grade: odds ratio [OR] 1.76, 95% CI 1.68-1.84), gender (boys vs girls: OR 1.18, 95% CI 1.15-1.22), urban status (urban vs rural: OR 1.10, 95% CI 1.01-1.19), and cigarette smoking (yes vs no: OR 6.67, 95% CI 5.83-7.62).

CONCLUSIONS

Although the prevalence of secondhand smoke exposure among Chinese adolescents declined from 2013-2014 to 2019, it remains unacceptably high. More effective strategies and stronger action are needed in China to further, and dramatically, curb secondhand smoke exposure among adolescents.

Authors: Nitschke Marlies , Nwosu Obioma Bertrand , Grube Lara , Knitza Johannes , Seifer Ann-Kristin , Eskofier Bjoern M , Schett Georg , Morf Harriet
Published: March 2023

BACKGROUND

Mobile eHealth apps have been used as a complementary treatment to increase the quality of life of patients and provide new opportunities for the management of rheumatic diseases. Telemedicine, particularly in the areas of prevention, diagnostics, and therapy, has become an essential cornerstone in the care of patients with rheumatic diseases.

OBJECTIVE

This study aims to improve the design and technology of YogiTherapy and evaluate its usability and quality.

METHODS

We newly implemented the mobile eHealth app YogiTherapy with a modern design, the option to change language, and easy navigation to improve the app’s usability and quality for patients. After refinement, we evaluated the app by conducting a study with 16 patients with AS (4 female and 12 male; mean age 48.1, SD 16.8 y). We assessed the usability of YogiTherapy with a task performance test (TPT) with a think-aloud protocol and the quality with the German version of the Mobile App Rating Scale (MARS).

RESULTS

In the TPT, the participants had to solve 6 tasks that should be performed on the app. The overall task completion rate in the TPT was high (84/96, 88% completed tasks). Filtering for videos and navigating to perform an assessment test caused the largest issues during the TPT, while registering in the app and watching a yoga video were highly intuitive. Additionally, 12 (75%) of the 16 participants completed the German version of MARS. The quality of YogiTherapy was rated with an average MARS score of 3.79 (SD 0.51) from a maximum score of 5. Furthermore, results from the MARS questionnaire demonstrated a positive evaluation regarding functionality and aesthetics.

CONCLUSIONS

The refined and tested YogiTherapy app showed promising results among most participants. In the future, the app could serve its function as a complementary treatment for patients with AS. For this purpose, surveys with a larger number of patients should still be conducted. As a substantial advancement, we made the app free and openly available on the iOS App and Google Play stores.

Authors: Moell Birger
Published: March 2023

BACKGROUND

Rapid advancements in natural language processing have led to the development of large language models with the potential to revolutionize mental health care. These models have shown promise in assisting clinicians and providing support to individuals experiencing various psychological challenges.

OBJECTIVE

This study aims to compare the performance of two large language models, GPT-4 and Chat-GPT, in responding to a set of 18 psychological prompts, to assess their potential applicability in mental health care settings.

METHODS

A blind methodology was employed, with a clinical psychologist evaluating the models' responses without knowledge of their origins. The prompts encompassed a diverse range of mental health topics, including depression, anxiety, and trauma, to ensure a comprehensive assessment.

RESULTS

The results demonstrated a significant difference in performance between the two models (p < 0.05). GPT-4 achieved an average rating of 8.29 out of 10, while Chat-GPT received an average rating of 6.52. The clinical psychologist's evaluation suggested that GPT-4 was more effective at generating clinically relevant and empathetic responses, thereby providing better support and guidance to potential users.

CONCLUSIONS

This study contributes to the growing body of literature on the applicability of large language models in mental health care settings. The findings underscore the importance of continued research and development in the field to optimize these models for clinical use. Further investigation is necessary to understand the specific factors underlying the performance differences between the two models and to explore their generalizability across various populations and mental health conditions.

Published: March 2023

Precipitation estimation models are typically sourced by rain gauges,
weather radars and satellite observations. A relatively new technique of
precipitation estimation relies on the network of Commercial Microwave
Links (CMLs) employed for cellular communication networks: the
rain-inducted attenuation in the links enables the precipitation
estimation. In the paper it is analysed to what extent the precipitation
derived from CML attenuation data is useful in estimation of the
precipitation field with the high temporal and spatial resolution
required in nowcasting models. Two methods of determination of
precipitation along CMLs from attenuation of signal with several
frequencies were proposed. Then, in order to generate precipitation
field, three approaches for assigning appropriate precipitation values
to a specific point or set of pixels along the link are developed and
tested. The CML-based estimates are compared to point observations from
manual rain gauges and multi-source precipitation fields using daily and
hourly accumulations. It was found that the CLM-based precipitation
fields are much worse than radar-derived estimates. At the same time,
they had slightly poorer reliability than spatially interpolated
telemetric rain gauge data and significantly higher reliability than
satellite estimates.

Thermoregulatory strategies of songbird nestlings reveal limited capacity for cooling and high risk of dehydration
Authors: Diehl Jenna , Alton Lesley , White Craig , Peters Anne
Published: March 2023

Developing young are particularly sensitive to environmental challenges,
often with life-long consequences, but the risks of climate warming
during this period are not well understood. To quantify the
physiological effects of increasing temperatures for developing
endotherms, we measured metabolic rate, water loss, and heat dissipation
behaviours between 25-45°C in nestlings of a free-living songbird. The
thermoneutral zone ranged from 33.1–42.3°C – higher and narrower than
adults – and metabolic rate increased sharply above and below this
range. Water loss was constant below 33.5°C, above which it increased
sharply, when nestlings also drooped their wings to lose heat. Despite
nestlings initiating panting (p50) around 40°C, water loss was never
sufficient to dissipate metabolically produced heat, indicating poor
cooling capabilities. Our data show that while developing young appear
relatively tolerant to higher temperatures, they are at a high risk of
dehydration and hyperthermia, with limited ability to mitigate these
risks of increasing temperatures.
Serbia’s approach to the EU and Russia - implications for its internal and foreign policy
Authors: Jovic-Lazic Ana , Ladjevac Ivona
Published: March 2023

This article examines Serbia?s approach to European integration and relations
with Russia and its implications for its internal and foreign policy.
Serbia?s policy is characterized as a ?small state? foreign policy designed
to maintain good relations with the EU and Russia, believing that this will
help it overcome internal and international challenges. In light of the
tense relations between the West and Russia, the article examines how this
policy has developed over the last two decades and whether it is sustainable
in changed international circumstances. It focuses on the fact that Serbia?s
approach toward the EU and Russia has shown continuity despite the growing
polarization at the international level caused by the crisis in Ukraine in
2014. However, due to the rapid and dramatic deterioration of EU-Russia
relations caused by Russia?s attack on Ukraine, Serbia?s current policy has
become very difficult to maintain. Serbia?s pragmatic policy, shaped by
internal and foreign political interests and guided by a series of economic,
legal, and security arguments, was put to the test. These arguments have
emerged as new key trends in Serbia and can be traced through the state?s
response to the war in Ukraine and the EU and Russia?s responses to the
country?s policy. Serbia found itself under pressure from both sides to
choose one side over the other, which causes tension and uncertainty and put
the country in a difficult position. This article shows that despite the
pressure and expectations of both sides, there was no drastic change in
Serbia?s policy towards the EU or Russia. However, the fact is that there is
less space for the fulfillment of the country?s foreign policy priorities,
which now seem mutually incompatible. Therefore, in a broader sense, this
article calls into question the sustainability of Serbia?s current foreign
policy as a framework for preserving the strategic and national interests of
the country.
What is hope? Hope, desire and possibility

In the presentation, I will deal with the meaning of the word ?hope?, as well
as the analysis of cases in which its use is rational and justified. First,
I will present the classical meaning of that word, that is, the meaning in
which it is most often used today, as well as the conceptual network within
which its meaning is most often analyzed. Then I will examine the
relationships between the meaning of that word and the meaning of the words
possibility, desire, belief and faith, optimism, as well as the word
expectation. Then I will move on to the latest attempts to better determine
the meaning of that word, due to some counterexamples, which threaten the
classical analysis.

Achilles tendon ruptures are the most common tendinous lesions in the adult population. The incidence has been rising, and it is more common between men and athletes. Achilles tendon rupture is a very relevant injury for athletes as it can threaten their career, with 20% to 40% not returning to elite sport. With the advent of better rehabilitation programs and new options available, the conservative treatment has become more popular and recent studies demonstrated similar outcomes compared with surgery. The conservative option is based on the principle of cast splint immobilization or functional braces, early weight-bearing and physical rehabilitation. The surgical treatment is based in open, mini-open and percutaneous approaches, with the goal to restore length and tension of the tendon. Percutaneous and mini-open techniques seem to have some benefit, as they reduce the risk of complications and an earlier return to physical activities.

The development of mining industrialization are factors that have favored the pollution of aquatic ecosystems. The main purpose of this study was to assess the influence of physico-chemical parameters of surface waters on the abundance of hydrophytes in 5 wetlands in Kipushi city, Haut-Katanga Province in DRC. Samples were collected from four rivers, of which: Kanyameshi, Kafubu, Kipushi, Kamarenge and Lake Kamarenge. The study used the presses for the preparation of herbariums as well as multifunction probe for physico-chemical analyses in situ and a spectrophotometer (415 nm) for some parameters. For environmental observations, the analysis of sediments allows to assess the pollution level by metallic trace elements, which breaks the ecological balance of this aquatic ecosystem. The abundance indices of plant species in each waterbody were subjected to a Factorial Component Analysis in order to identify the distribution of the elements of the dominant plant associations. Data analysis was performed using PAST software. The findings showed 29 species distributed in 26 genera, 13 families and 11 orders. The Confirmatory Factor Analysis showed the distribution of plant groupings following a gradient of mineralization of the zones as well as that of abundance-dominance. Physico-chemical parameters influence the distribution of hydrophytes in wetlands. They constitute indicators of toxicity having an adverse consequence on the aquatic ecosystem for these metallic elements are not biodegradable. The more there is accumulation of dissolved metals in water, the more they create an environmental hazard.

The peculiarity of solid bodies of organic origin, in contrast to solid bodies of mineral origin, is that their internal structure is characterized by the presence of two spaces - cellular and intercellular. Such bodies tend to swell upon contact with the extractant. The phenomenon of swelling, during extraction, is always accompanied by the dissolution of target substances contained in the cellular and intercellular space. All these processes create conditions for the diffusion of the dissolved target substance through the cell membrane into the intercellular space, and then through the intercellular space beyond the boundaries of the solid phase particle. This helps to increase the volumes of the cellular and intercellular environment. The absolute value of the volumes of cellular and intercellular spaces is one of the most important values when developing and calculating extraction processes and forecasting environmentally safe technologies for obtaining biologically active compounds. The work presents a method of experimentally calculating the volumes of intercellular and cellular spaces of medicinal plant raw materials of various morphological organs. The established absolute values of the volumes of the cellular and intercellular spaces make it possible to calculate the order of diffusion coefficients of biologically active compounds in the medium of the intercellular space, as well as in the cell membrane. In the future, the determined values of the volumes provide grounds for predicting the regime, kinetics and dynamics of extraction of target substances during the implementation of an environmentally safe technology for obtaining biologically active compounds in production, as well as to support the monitoring of production processes of extraction in digital mode.

Dynamics of the oil reservoir depletion

In order to study the dynamics of depletion in heterogeneous oil reservoirs on the base of combined finite-element-difference method for the non-stationary problem of piezoconductivity we have carried out a numerical simulation of the pressure distribution in vicinity of the operating well. At that we have taken into account the heterogeneous distribution of filtration characteristics inside the reservoir and the oil infiltration parameters on the boundaries of the reservoir. The developed method for solving the non-stationary problem of piezoconductivity in deformed oil formations allows us adequately to describe the distribution of pressure near production and injection well systems in real operating conditions. We have shown that depletion processes in vicinity of the active well mainly depend on the intensity of oil production and the degree of oil infiltration at the boundaries of the reservoir’s area and to a lesser extent on the filtration parameters inside the reservoir. Therefore, in order to maintain the proper level of oil production in the reservoir’s area, it is necessary, for example, thanks to the use of modern technologies (system of injection wells), to ensure a sufficient inflow of the oil phase at the borders of the considered area. We have shown that in the cases of low oil infiltration at the boundaries of the reservoir area, the value of depletion is directly proportional to the production power of the well. At the same time, a decreasing of the reservoir permeability leads to a slow downing of depletion processes. The limiting value of the oil boundary infiltration coefficient, which allows achieving industrial oil production, is m. At that, the time of reaching of the stationary productive regime is directly proportional to the value of the oil permeability coefficient inside the reservoir. Before installing a system of production and injection wells in heterogeneous oil reservoirs, it is necessary to carry out a systematic analysis of the degree of depletion of the working reservoir’s areas in order to place them in such a way that would ensure the effective dynamics of filtration processes around these areas.
