This paper analyzes the design of a force‐based impedance control for a haptic interface system characterized by a parallel kinematics. By exploiting the features of parallel mechanisms, which perform better than the serial ones in terms of dynamic performance, stiffness and position accuracy, and by implementing a closed‐loop force control, the transparency of a haptic master system and the fidelity of resultant force feedback can be consistently improved. Issues for design and control as well as aspects of performance evaluation of haptic interfaces are treated within the paper and some results of the experimental characterization of a haptic interface are presented.

Flexible pressure sensor arrays have promising applications in analog haptics, reconfiguration of sensory functions, artificial intelligence, wearable devices and human-computer interaction. The force disturbance generated by the connecting material between the sensor array units will reduce the detection accuracy of the unit. The purpose of this paper is to propose a flexible pressure sensor with interference immunity capability. A C-type bridge flexible piezoelectric structure is used to improve the pressure perturbation. The interference immunity capability of the sensor has been improved.

In this paper, a C-type pressure sensor array structure by rapid injection moulding is manufactured through the positive piezoelectric effect of a piezoelectric material. The feasibility of C-type interference immunity structure in a flexible sensor array is verified by further analysis and experiment. A flexible pressure sensor array with C-type interference immunity structure has been proposed.

In this paper, we present the results of the perturbation experiment results of the C-type pressure sensor array, showing that the perturbation error is less than 8%. The test of the flexible sensor array show that the sensor can identify the curved angle of up to 120 °, and the output sensitivity of the sensor in the horizontal state reaches 0.12 V/N, and the sensor can withstand the pressure of 80 N. The flexible sensor can work stably in the stretch rate range of 0–8.6% and the stretch length range of 0–6 mm.

In this paper, C-type pressure sensor array structure is fabricated by rapid injection moulding for the first time. The research in this paper can effectively reduce the disturbance of input pressure on the sensor’s internal array and improve the output accuracy. The sensor can intuitively reflect the number of fingers sliding on the sensor by the order in which the maximum voltage appears. Due to the strong interference immunity capability and flexibility of the flexible sensor array mechanism, it has a broad application prospect in the practical fields of haptic simulation, perceptual function reconstruction, artificial intelligence, wearable devices and human–computer interaction.

Retailers can use their mobile app to send location-based advertisements to consumers in the store. Goal congruence is an important driver for this type of ad's effectiveness. However, evidence of goal congruence influence on positive and negative outcomes and, in turn, on product purchase intention, is lacking. Research also leaves out the moderating effect of shopping motivation and price promotion level. The paper tests the impact of goal congruence on purchase intention through attitude to the ad and its intrusiveness, as well as the moderating effect of shopping motivation and price promotion.

Two online experiments are conducted to investigate these effects. The first experiment investigates the influence of goal congruence (i.e. low vs high) and the moderating effect of shopping motivation (i.e. utilitarian vs hedonic) on attitudes to the ad, level of perceived intrusiveness and, ultimately, purchase intention. The second experiment introduces the moderating effect of price promotion.

Goal congruence has a positive effect on attitude to the ad but no impact on intrusiveness. Goal congruence and shopping motivation further have a significant effect on attitude to the ad, as well as on purchase intention. Finally, no interaction effect of price promotion level is found.

This study tests the effect of goal congruence for in-store mobile apps on attitude towards the ads and intrusiveness and ultimately purchase intention. It further tests the moderating effect of shopping motivation (i.e. utilitarian vs hedonic) and price promotion level on these relationships.

The main aim of this study is to study the effect of alkyl dimethyl benzyl ammonium chloride on removing stains, yellowness and harmful metal ions on historical printed paper, as well as the effect of this cleaner on optical and chemical properties of treated paper.

The assessments after and before treatment were carried out using digital microscopy, infrared spectroscopy (FTIR), pH measurement, color change and finally scanning electron microscopy.

The results showed that the concentrations used under study (1% and 3%) cleaned the paper efficiently without any observed effect on the chemical composition of cellulose, which was confirmed by IR spectra. The most stains that completely disappeared were the soil spots, also the pH values had improved significantly after treatment, which confirms that the detergent is effective in neutralizing the acidity of cellulose. Moreover, the color change revealed an increase in the chromatic lightness of the paper after treatment, which agreed with the results of the scanning electron microscopy examination, as the paper appeared free of dirt, and the fibers and bundles became more cohesive.

To the best of the authors’ knowledge, this study is a unique study, as there is no previous literature that has indicated the use of the effect of alkyl dimethyl benzyl ammonium chloride washing treatments for printed historical paper, as it was limited only to making disinfection materials and water purification products.

The purpose of this meta-analysis is to encapsulate the outcomes and generate meaningful conclusions by examining the factors that influence consumers' purchase and non-purchase behaviour intention in a virtual reality retailing context.

This study integrates the outcomes from 52 studies, including 403 relationships involving 19,188 samples. The analysis was conducted using R-metafor and AMOS software.

The findings indicate that key factors that influence purchase and non-purchase behavioural intentions are virtual reality (VR)characteristics, virtual reality experience and consumer attitudes. VR experience is the strongest predictor for purchase decisions in virtual environment ,while consumer attitude towards VR most strongly influences the non-purchase behaviour of the consumers. Furthermore, the age of the respondents, cultural backgrounds (high vs low power distance) and gender moderate the relationship between consumers' attitudes and purchase and behaviour intentions.

Marketers can positively influence consumer attitudes and behavioural intentions by prioritizing the design of the virtual environment and facilitating unique experiences (by manipulating different sensory stimuli) in virtual retailing.

The current meta-analysis reconciles and reinforces the findings in the extant literature and provides a robust empirical generalization of the critical factors that influence consumers' purchase or behavioural intentions in a virtual retailing context.

Influx of labor migrants into Russia makes it necessary to put TB prevention measures in place, both inside and outside of Russian borders. While inside Russia TB response is premised on testing migrants applying for work or residence permits for diseases of public significance, millions of migrants – specifically, those working without completing necessary paperwork – evade this requirement. In light of that, the purpose of this paper is to propose introducing disease screening in migrant-sending countries, i.e. testing of potential migrants for infectious diseases in local medical institutions certified by Russian authorities.

To support the proposal, the authors provide review of official data on TB prevalence among migrants in Russia as well as publications on international experience with conducting disease screening in migrant-sending countries.

Available studies demonstrate that conducting disease screening programs in migrant-sending countries is associated with earlier detection of TB cases, shorter period of infectiousness and hospitalization, and significant savings in health budget.

Taking into account this experience, the authors propose introducing disease screening programs in CIS both under current legal arrangements and with the requirement for labor migrants to produce medical certificate when entering Russia being introduced. The need for trans-border cooperation in assuring positive health outcomes among labor migrants is also highlighted.

For the robot-assisted upper limb rehabilitation training process of the elderly with damaged neuromuscular channels and hemiplegic patients, bioelectric signals are added to transform the traditional passive training mode into the active training mode.

This paper mainly builds a steady-state visual stimulation interface, an electroencephalography (EEG) signal processing platform and an exoskeleton robot verification platform. The target flashing stimulation blocks provide visual stimulation at the specified position according to the specified frequency and stimulate EEG signals of different frequency bands. The EEG signal-processing platform constructed in this paper removes the noise by using Butterworth band-pass filtering and common average reference filtering on the obtained signals. Further, the features are extracted to identify the volunteer’s active movement intention through the canonical correlation analysis (CCA) method. The classification results are transmitted to the upper limb exoskeleton robot control system, combined with the position and posture of the exoskeleton robot to control the joint motion of robot.

Through a large number of experimental studies, the average accuracy of offline recognition of motion intention recognition can reach 86.1%. The control strategy with a three-instruction judgment method reduces the average execution error rate of the entire control system to 6.75%. Online experiments verify the feasibility of the steady-state visual evoked potentials (SSVEP)-based rehabilitation system.

An EEG signal analysis method based on SSVEP is integrated into the control of an upper limb exoskeleton robot, transforming the traditional passive training mode into the active training mode. The device used to record EEG is of very low cost, which has the potential to promote the rehabilitation system for further widely applications.

High volume of international migration calls for the establishment of financial and organizational mechanisms that would ensure provision of treatment for tuberculosis (TB) among migrants. In the case of countries like Russia where budget funding goes for TB treatment, the need is acute as delivering these services is affected by social perception that they should be provided to taxpayers only. While official policies in Russia promote voluntary medical insurance as a way to cover their health care needs, the problem is that neither voluntary medical insurance, nor the National Medical Insurance Plan, extend to cover the treatment of infectious diseases, such as TB making proposal of possible alternatives to these delivery vehicles appropriate. The paper aims to discuss these issues.

The analysis includes review of survey results on the extent of medical insurance coverage among migrants as well as legal provisions concerning access to medical care among migrants in Russia and some other migrant-receiving countries.

This exercise illuminates the public health risks and economic consequences related to inadequate access to medical help among migrants. Availability of medical insurance even among socially integrated segment of this group is limited. Also of notice is that citizens of Belarus as opposed to others are granted access to the full range of TB services in Russia.

Using this precedent, the authors propose an alternative mechanism – Inter-State Medical Insurance Fund – to be established by governments of CIS countries, with national allocations covering the provision of medical help to labor migrants from the respective countries in Russia.

Mobile promotion has become an important and popular mechanism for mobile commerce, with many companies using this approach to increase sales and drive brand satisfaction toward the use of mobile apps. Despite the crucial nature of this topic, knowledge on the value of mobile promotion remains insufficient. Drawing upon consumption value theory (CVT), this study aims to examine the underlying mechanism that drives app satisfaction and in-app purchase.

In this research, the authors selected retail mobile apps for empirical testing. The authors recruited 476 users to complete a survey and analyzed the results using partial least squares structural equation modeling.

The results revealed that functional (monetary savings and localization), social (self-expression), emotional (entertainment), epistemic (exploration) and conditional (personalization) value increase the desirability of mobile promotion, thereby facilitating app satisfaction and in-app purchase.

Amid the vast business opportunities of mobile commerce, numerous brands have developed mobile apps that function as platforms for the promotion, provision and purchase of products and services. With the prevalence of mobile app downloads, apps have become the primary mobile platform for conducting mobile promotion. This research contributes to the literature and offers retailers insight into how to create value that can increase app satisfaction and in-app purchasing through mobile promotion.
