The Development Course of Modern Educational Technology in China

In the late 19th and early 20th centuries, with the progress of science and technology, new media continuously entered the field of education, promoting the development of educational technology. In the Current Educational Technology stage, the theories and practices of educational technology in the United States have significant influence. This article mainly takes China and the United States as examples to briefly describe the development process of modern Educational Technology domestically and internationally. The evolution of Educational Technology in the United States comprises two parallel threads: one is the development of media technology (materialized technology), and the other is the development of intelligent technology (non-materialized technology). The interaction and organic integration of two threads constitute the development history of Educational Technology. Modern Educational Technology in China started with electrified education. It emerged in response to the developmental needs of the country, drawing on foreign technology and experience to address urgent issues related to the public's diathesis at the time. From its inception, it embarked on a different development path from other countries, known as "big electrified education". The development process of modern Educational Technology in China can be divided into five stages in terms of time: newly established, lay a foundation, development, transformation, and in-depth development. This has resulted in the creation of a unique field of Educational Technology in the world, encompassing Educational Technology disciplines (including majors), undertakings, and industries.

ANALYTICITY OF MARKOV PROCESSES FOR DESCRIPTION OF COEFFICIENT OF TECHNICAL READINESS OF GRAIN HARVESTERS COMBINES

The article presents the results of a study of the influence of operating conditions and modes on the technical condition of grain harvesters. The grain harvester gradually loses its performance during operation. To ensure stable operation of the fleet of agricultural machines, maintain its technical condition and increase operational reliability, technical control of grain harvesters is carried out. The analysis of the technical condition of combine harvesters showed that there remains a high percentage of defective combine harvesters, downtime for all types of repairs and the number of unplanned repairs. One of the main reasons for this condition is the low level of organization and quality of technical control, insufficient mechanization of technological processes. The basic element of the technological preparation of repair production is the development of a technological process that ensures the availability of a complete set of technological documentation at the enterprise for organizing and carrying out technical maintenance and repairs of traction rolling stock. During the development of technological processes of repair, the selection of technological operations and means of their technological equipment, normative documents of requirements for tolerances, clearances, forces of landings, pressings, threaded connections, processing quality, assembly accuracy, etc. is carried out. Technical conditions for the development of non-standard technological equipment are determined from the developed technological operations. As a target function, the rational periodicity of maintenance of grain harvesters was taken, namely, the rational time between services. The analysis of the results of known works on mathematical modeling and periodicity of repair and maintenance of complex technical systems based on Markov and semi-Markov processes allowed us to propose complex criteria as criteria for modeling the objective function: the functional of readiness, which is used to estimate the allowable time, and the functional of technical use, which allows determining the value of the optimal time between services of the combine harvester according to the technical parameter at the maximum point.

Development of science and technology in India

Before understanding the development process of science and technology in India during colonial rule, it is necessary to understand what science is. Science is a way of gaining knowledge which leads us to such beliefs. Which can be verified on the basis of logic and experiments. In English it is called Justified True Beliefs. In short, the foundation of science is based on direct evidence i.e. Positilist MPricipm. The science that was coming with the new technology had no existing roots in India. In modern science, theory and experiment go together. It was so in Europe but such scientific vision had not emerged in India. It is often said very strongly that modern science was present in ancient Indian thought and that India had a very old tradition of science and technology. It is true that India before the arrival of the Europeans was not an intellectual void, but there is no special justification for this when we see that even at that time only a limited and exclusive class had the right to acquire knowledge. At the beginning of the colonial period, nothing was happening in terms of science and technology in India. A fundamental difference between the ancient and modern scientific traditions is that in the ancient Indian tradition, there was progress in various fields of science but no significant achievements were made at the mechanical level. Whereas the biggest achievement of the modern scientific tradition has been the development of mechanics in it. The development of mechanics promoted new research in the field of science.

Plasmon-enhanced second harmonic generation of metal nanostructures.

As the most common nonlinear optical process, second harmonic generation (SHG) has important application value in the field of nanophotonics. With the rapid development of metal nanomaterial processing and chemical preparation technology, various structures based on metal nanoparticles have been used to achieve the enhancement and modulation of SHG. In the field of nonlinear optics, plasmonic metal nanostructures have become potential candidates for nonlinear optoelectronic devices because of their highly adjustable physical characteristics. In this article, first, the basic optical principles of SHG and the source of surface symmetry breaking in metal nanoparticles are briefly introduced. Next, the related reports on SHG in metal nanostructures are reviewed from three aspects: the enhancement of SHG efficiency by double resonance structures, the SHG effect based on magnetic resonance and the harmonic energy transfer. Then, the applications of SHG in the sensing, imaging and in situ monitoring of metal nanostructures are summarized. Future opportunities for SHG in composite systems composed of metal nanostructures and two-dimensional materials are also proposed.

THERMODYNAMICS OF STEPWISE DISSOCIATION OF GLYCYL-D-PHENYLALANINE IN AQUEOUS SOLUTION

Recently, more and more drugs that are derivatives of oligopeptides have been introduced to the pharmaceutical market. The structural elements of these compounds are amino acids and dipeptides. When stabilizing functional groups are introduced into the peptide structure, as well as through the use of special delivery systems, oligopeptide derivatives can be used as innovative medicines. The calorimetric method was used to determine the heat of interaction of glycyl-D-phenylalanine with solutions of nitric acid and potassium hydroxide at 298.15K and the values of the ionic strength of the solution 0.5, 0.75 and 1.0 in the presence of KNO3. Measurements were carried out on a calorimeter with an isothermal shell and automatic recording of the temperature-time curve. The unit was equipped with a reaction vessel with a volume of 60 cm3. Calibration was performed by current at T = (293.15–308.15) ± 0.01 K and P = 100.5± 0.7 kPa. A thermistor KMT-14 was used as a temperature sensor. The temperature of the calorimetric cell was controlled in a thermostat equipped with a PID controller with an accuracy of 0.002 K. The temperature sensor of the thermostat was a platinum resistance thermometer. The calorimeter was calibrated by current. The volume of the calorimetric liquid is 42.83 ml. The enthalpy of stepwise dissociation of glycyl-D-phenylalanine at zero ionic strength was found by an equation with one individual parameter. Standard thermodynamic characteristics (ΔrH°, ΔrG°, ΔrS°) of acid-base interaction reactions in aqueous solutions of glycyl-D-phenylalanine are calculated. The effect of the background electrolyte concentration on the dissociation heats of glycyl-D-phenylalanine is considered. Knowledge of the thermochemical characteristics of dipeptides is necessary for understanding and subsequent modeling of the process of protein biosynthesis occurring in biological systems. Data on the thermodynamic characteristics of dipeptide solutions are needed in various fields where these compounds are used: pharmacology, medicine, food and cosmetic industries, for the development, justification and optimization of technological processes involving these compounds and their complexes with metals.

Design And Development of a Compact Improvised Biogas Harvester

This research project aimed to design and create an affordable and locally- sourced biogas harvester for backyard livestock raisers. The device is called Compact Improvised Biogas Harvester (CIBiH) and is a more cost-effective alternative to the foreign-made inflatable biogas harvesters available in the market. The study used the CDDIR model, a 5-phase technological development process consisting of Conceptualization, Designing, Development, Initial Testing, and Refinement stages. The goal was to create a prototype that is more effective, cost-efficient, and readily available, eliminating the need for external sources of energy like electricity and fuel in the biogas harvesting process. However, the project still requires further evaluation to determine whether it meets industry manufacturing standards for mass production.

Bio-Experiential Technology to Support Persons With Dementia and Care Partners at Home (TEND): Protocol for an Intervention Development Study.

Alzheimer disease and related dementias are debilitating and incurable diseases. Persons with dementia and their informal caregivers (ie, dyads) experience high rates of emotional distress and negative health outcomes. Several barriers prevent dyads from engaging in psychosocial care including cost, transportation, and a lack of treatments that target later stages of dementia and target the dyad together. Technologically informed treatment and serious gaming have been shown to be feasible and effective among persons living with dementia and their care partners. To increase access, there is a need for technologically informed psychosocial interventions which target the dyad, together in the home. This study aims to develop the toolkit for experiential well-being in dementia, a dyadic, "bio-experiential" intervention for persons with dementia and their caregivers. Per our conceptual model, the toolkit for experiential well-being in dementia platform aims to target sustained attention, positive emotions, and active engagement among dyads. In this paper, we outline the protocol and conceptual model for intervention development and partnership with design and development experts. We followed the National Institutes of Health (NIH) stage model (stage 1A) and supplemented the model with principles of user-centered design. The first step includes understanding user needs, goals, and strengths. We met this step by engaging in methodology and definition synthesis and conducting focus groups with dementia care providers (N=10) and persons with dementia and caregivers (N=11). Step 2 includes developing and refining the prototype. We will meet this step by engaging dyads in up to 20 iterations of platform β testing workshops. Step 3 includes observing user interactions with the prototype. We will meet this step by releasing the platform for feasibility testing. Key takeaways from the focus groups include balancing individualization and the dyadic relationship and avoiding confusing stimuli. As of September 2023, we have completed focus groups with providers, persons with dementia, and their caregivers. Additionally, we have conducted 4 iterations of β testing workshops with dyads. Feedback from focus groups informed the β testing workshops; data have not yet been formally analyzed and will be reported in future publications. Technological interventions, particularly "bio-experiential" technology, can be used in dementia care to support emotional health among persons with a diagnosis and caregivers. Here, we outline a collaborative intervention development process of bio-experiential technology through a research, design, and development partnership. Next, we are planning to test the platform's feasibility as well as its impact on clinical outcomes and mechanisms of action. DERR1-10.2196/52799.

Informational, technological, economic and financial sovereignty as the newest types of autonomy

Currently, the problems of sovereignty in various functional areas have significantly expanded, which is naturally reflected in modern research, which is influenced by the processes of digitalization, technology development, and foreign policy aspects on the agenda.With progress and development, the newest threats to the Russian Federation have emerged, namely its independence and independence, which are inextricably linked and interdependent with the socio-economic development of the Russian state, the state of protection of its interests. The relationship between the established components of sovereignty — the supremacy and independence of state power throughout the territory as static elements with the functional side of the implementation of these components through new spheres of public relations is unconditional, and this fact should be taken into account in the current concept of sovereignty. The newest types of sovereignty highlighted in the article are objectively significant, but so far, in terms of the level of general theoretical elaboration, they are still “lagging” behind the “classical” theory of sovereignty that has developed within the framework of public law, both in terms of the scale of elaboration and in legal regulation.

IMAGINING THE FUTURE OF AGETECH

Abstract The intersection of global population aging and technological trends in e-health, robotics, artificial intelligence, and mobile technologies has led to the emergence of “AgeTech” as a way to improve the health and well-being of older people. While this might be seen as an almost deterministic process of technological change, the visioning, development and implementation of technology is essentially a creative and socially-situated process. This requires us to understand AgeTech as a socio-technical imaginary, examining the intersecting spheres of social action and technological development. This idea of technological development as a creative process, runs counter to an idea of technology in purely rational and instrumental terms and brings into play cultural, political and behavioural factors. Our symposium examines the socio-technical imaginary of AgeTech in three papers: Paul Higgs and Chris Gilleard discuss Fourth Ageism and the Technological Imaginary of Long-term care and argue that the problematizing of aging present in current thinking needs to be challenged at the conceptual stage of technological development. Andrew Sixsmith et al will present on A Global AgeTech Agenda, with a particular focus on how AgeTech development and innovation should connect with global initiatives such as the UN’s Strategic Development Goals. Mei Lan Fang et al will take an Ethical Perspective on AgeTech to discuss some of the complex challenges around the creation and use of technologies and argue that culture change is needed within the research and innovation communities to develop ethically grounded AgeTech. This is a Technology and Aging Interest Group Sponsored Symposium.

LEVERAGING AN “ETHICAL BY DESIGN” APPROACH TO CREATE MORE INHERENTLY RESPONSIBLE TECHNOLOGY TO SUPPORT AGING

Abstract Responsible technologies are technologies that appropriately support the needs, abilities, and values of the people using them. While many aspects of responsible technology are ubiquitous, there are a multitude of considerations that are specific to older adults. These age-related aspects must be properly understood and incorporated into the technology development and selection process if technology is to be inclusive of and useful to older adults. However, as many of these aspects are subjective, qualitative, and/or dynamic, developers often consider them to be too abstract, undefined, or difficult to address, resulting in their omission from the technology creation process. In this presentation we will discuss how we can leverage the concept of ‘Ethical by Design’ to drive the change in thinking and doing that is required to enable developers to engage with age-related concepts in technology design, development, and evaluation. Concepts such as user-centered design, values-based engineering, brave spaces, and co-creation will be presented as some of the ways we can directly access lived experiences and translate them into the creation of technologies that are more inclusive of older adults.

АНАЛИЗ МОРФОЛОГИИ ПРИ ВОЗДЕЙСТВИИ ЭЛЕКТРОЛИТИЧЕСКОЙ СТРУИ НА ПОВЕРХНОСТЬ НЕРЖАВЕЮЩИХ СТАЛЕЙ

The article is devoted to the study of the effect of an electrolytic jet on the surface of a metal anode. The studies were carried out in the electrolysis mode with a study of the transition to the electrolyte-plasma treatment mode. Special attention is paid to the mechanisms of formation of the morphology of the surface of stainless steels 08X18H9T, AISI 301, AISI 304. It is shown that for different steels, the process of electro-chemical dissolution of the anode material is accompanied by different mechanisms of dissolution of the micronerities of the microprofile. The current-voltage characteristics of the process in the voltage range in the range of 20-250 V. The effect of the decrease in the mass of the anode material on the current value is considered. The morphology of steels has been studied under different technological conditions and at different points of contact of the electrolytic jet with the surface. The criteria accompanying the transition to the electrolyte-plasma regime from the electrolysis regime are considered.The effect of an electrolytic jet on the risks formed by mechanical treatment on the anode surface is investigated. The influence of stress on the formed surface roughness parameter Ra is considered. The calculation of the electric field strength for surface nanodefects was performed in the Comsol Multithisics program. The results of this work can be used for the development of turbine blade processing technology, electrochemical cutting and nanoobrabotation of materials.

STRUCTURES OF ADAPTIVE SIGNAL PROCESSING SYSTEMS FOR RADAR SENSORS OF EXTERNAL INFORMATION FOR CORRELATION-EXTREME AIRCRAFT NAVIGATION SYSTEMS

During the guidance of the aircraft on the final part of the flight, it is affected, along with other external factors, by interferences of various (artificial or natural) origins. These interferences have various effects on the receiving elements of the antenna array of the radar sensor of external information. Due to the variability and rapidity of the complex interference situation, adaptive interference protection systems are the most effective in combating these interferences. It is known that the use of adaptive processing systems allows for overcoming the practically inevitable a priori uncertainty of statistical characteristics of signals and interference of various origins. At present, due to the development of digital technology, new methods and devices for adaptive signal processing against the back- ground of interference have appeared. Thus, the arsenal of methods of adaptation to Gaussian disturbances has been supplemented by methods involving the inversion (direct or recurrent) of the most plausible estimates of correlation matrices of disturbances or their regularized varieties. Wide possibilities of adaptation are opened up in modern radar stations with multi-element phased antenna ar- rays, which provide for digital information processing. Due to the very high speed of the aircraft during the operation of its correlation- extreme guidance system, as well as due to the dynamic and non-stationary interference environment, an important requirement for adaptive anti-jamming systems is their speed. The effectiveness of adaptive processing of signals against the background of interference can be significantly increased by using reliable a priori information. The paper considers a method of increasing the speed of adaptive protection systems against radar interference of various origins by taking into account a priori information about the central symmetry of the receiving channels of radar sensors of external information of correlation-extreme aircraft navigation systems. It is shown that taking into account such a priori information as the central symmetry of the receiving channels of radar sensors of external informa- tion leads to a corresponding change in the structure of devices for adaptive signal processing in the conditions of interference in these sensors and as a consequence, to an increase in their speed.

Enabling nurses’ engagement in the design of healthcare technology – Core competencies and requirements: A qualitative study

BackgroundDue to the globally increasing demand for care, innovation is important to maintain quality, safety, effectiveness, patient sensitivity, and outcome orientation. Health care technologies could be a solution to innovate, maintain, or improve the quality of care and simultaneously decrease nurses’ workload. Currently, nurses are rarely involved in the design of health care technologies, mostly due to time constraints with clinical nursing responsibilities and limited exposure to technology and design disciplines. To ensure that health care technologies fit into nurses’ core and routine practice, nurses should be actively involved in the design process. ObjectiveThe aim of the present study was to explore the main requirements for nurses’ active participation in the design of health care technologies. DesignAn exploratory descriptive qualitative design was used which helps to both understand and describe a phenomenon. ParticipantsTwelve nurses from three academic hospitals in the Netherlands participated in this study. MethodData were collected from semistructured interviews with hospital nurses experienced in design programs and thematically analysed. ResultsFour themes were identified concerning the main requirements for nurses to participate in the design of health care technologies: (1) nurses’ motivations to participate, (2) the process of technology development, (3) required competence to participate (such as assertiveness, creative thinking, problem solving skills), and (4) facilitating and organizing nurses’ participation. ConclusionNurses experience their involvement in the design process as essential, distinctive, and meaningful but experience few possibilities to combine this work with their current workload, flows, routines, and requirements. To participate in the design of health care technologies nurses need motivation and specific competencies. Organizations should facilitate time for nurses to acquire the required competencies and to be intentionally involved in technology design and development activities.

Metasurfaces toward Optical Manipulation Technologies for Quantum Precision Measurement

AbstractMetasurface‐based optical field manipulation has significantly broadened the application range of micro‐optical components and integrated optics, gradually replacing bulky and complicated optical components. With the continuous development of micro and nano processing technology as well as computational analysis technology, metasurfaces have progressively shown their superior application prospects. After demonstrating tremendous results in classical optical applications, their application range has now extended to the field of quantum sensing. Due to their unique properties, such as small planar size, easy integration, flexible performance design, and tunable functionality, they have opened up a series of novel and rich applications for generating, manipulating, controlling, and detecting optical fields. In this paper, the basic principle and implementation of quantum measurement are presented and an overview of the design principles of metasurfaces, along with a summary of the latest advancements and potential applications of these surfaces in optical field modulation techniques for quantum precision measurement. Additionally, a thorough discussion and analysis of the challenges encountered by metasurfaces and their future development prospects is provided. Metasurfaces offer brand‐new opportunities for low‐cost, high‐performance, multifunctional miniaturized quantum sensors and are expected to play a significant role in the development of next‐generation quantum sensors.
