Human Information Rights in Digital Space: To the 75th Anniversary of the Universal Declaration of Human Rights

An important milestone in the development of the institute of human rights is the adoption in 1948 of the Universal Declaration of Human Rights, which for the first time in history comprehensively enshrined the basic human rights and freedoms, taking into account the natural, political and social needs and interests of the person (individual). The adoption of this very document declared the man, his fundamental rights and freedoms to be the main value. The international community sought to cover all possible spheres of public relations (public and private) that are necessary for a person to function normally, consolidating basic rights and freedoms. It is impossible to deny the importance of this international legal act for the «human family» and each individual. At the same time, we may state that this document was adopted three quarters of a century ago and it does not fully reflect reality, does not take into account the dynamics of the development of public relations, in particular, does not define human rights in the emerging information society, in particular the digital space. After all, even the approach to individualization and identification of the person himself is changing, digital profiles of citizens appear, digital passports and other identification documents are issued, moreover, «cybermen» appear — individuals with subcutaneously implanted microchips (capsules) with NFC technologies (Near Field Communication), containing information, in particular, about personal and banking data.

Analysis of Smart Technologies Used in Smart Hotels

Purpose –The development and widespread use of smart technologies have led to the emergence of smart hotels. Smart hotels are smart systems that provide benefits to all stakeholders (staff, managers, customers, hotel owners) in the hospitality sector with smart technologies and interact with each other. Hotels that utilize smart technologies differentiate the hotel service, provide superiority in competition, and reduce hotel costs. This study aims to analyze the hotels in the world where smart technologies are used and the type, purpose of use, and customer touchpoints of the smart technologies used in these hotels and to provide a perspective and foresight for hotels.Design/methodology/approach –The data used in the research were obtained from secondary sources. The document analysis method, one of the qualitative research methods, was used to analyze the sources. The content analysis technique was used to analyze the data. A seven-step systematic review process was applied in the research. The seven-step review process consists of the following stages: (1) determining the review objectives and formulating the research questions; (2) determining the search terms and selection criteria; (3) searching for smart hotel applications before clarifying the exclusion and inclusion criteria; (4) evaluating the quality and suitability of smart hotel applications; (5) determining the content analysis review variables (6) conducting content analysis, and (7) synthesizing and reporting the findings. The population of the research consists of all hotels where smart technologies are used. In the research, 1084 smart hotels were determined as a sample.

Integration of processes related to the implementation of the mediGOAT platform in diabetic patient care.

Diabetes has always been viewed through the prism of the fact that any expenditure in this area is a threat to the budget of the entire health care system. Most often it is the progress of science that forces integration activities. An example may be the integration processes related to the implementation and creation of the mediGOAT platform, which are focused on its multi-functionality, i.e. the ability to connect many different measuring devices (Glucometer, CGM, SmartPen, Insulin Pump, GlucoActive) from many manufacturers. They are made up of smaller particles with their own rules and goals, such as engaging and evaluating activities. We meet with this, among others by implementing good practices.
 As a result, such activities give the user more choice and independence from many native applications (manufacturers), and it enables cooperation with Google Health and iHealth (Apple). This makes it possible to use additional information provided by External Applications (meals, exercise, pressure, weight, ...) in the treatment process. In addition, it allows you to collect and store your medical records (including the results of medical tests). The indicated/selected medical/health data (in the future on-line measurements) can be provided to the doctor via the Portal, ensuring security (login via Apple and Google, Backup) and ease of use.
 Additional knowledge is written at various levels of detail, scattered in different places, its origin is sometimes uncertain, which makes it unreliable. It is often oversized where it is not necessary, and various sources can contradict each other. Therefore, it is important to use trusted sources. Controlling blood glucose levels is important, as are the circumstances surrounding such a measurement, what you do and where you are. Mobile Continuous Glucose Monitoring, using CGM, enables up to 288 readings per day, giving you insight into information that fingerstick tests cannot match. CGM provides real-time glucose readings every five minutes throughout the day and night, notifying you of high and low values. The sensor continuously measures the glucose level just below the skin and transmits the data wirelessly to the display device via the transmitter. This enables an immediate reaction. A discreet sensor placed just under the skin (the automatic applicator introduces the sensor just under the skin with one press) measures the glucose level for the time specified by the manufacturer. Glucose data is sent wirelessly to the analysing and smart device via Bluetooth® or NFC technology. Such a device can be a compatible smartphone or other optional receiver that displays and archives glucose data in real time.

Passive and wireless NFC tag-type trimethylamine gas detection based on WO3/MXene composite sensors

In this paper, we developed a high-sensitive WO3/MXene composite based gas sensor. The morphology, crystal structure, and chemical composition of the pure WO3, MXene and WO3/MXene composite were analyzed by several characterization means include SEM, XRD, and XPS, proving that the successful synthesis of WO3 nanoparticles, MXene nanosheets and WO3/MXene composites. The trimethylamine sensing element was fabricated by spin coating the prepared sensitive materials on the interdigital electrodes. The gas-sensing performance of the sensor was investigated at 25 oC, 23% RH, and the results demonstrate that the WO3/MXene based sensor has excellent response (Ra/Rg = 277.78 @10 ppm), fast response/recovery time (2 s/3 s @ 2 ppm) towards trimethylamine. It also holds excellent repeatability, selectivity, short-term and long-term stability. As a result, we have found that the addition of MXene has greatly improved the performance of WO3 for trimethylamine detection at room temperature. Finally, a tag-type gas detection device based on NFC technology has been developed to achieve detection. When testing, we only need to place a sensor label without power supply in the gas environment, and the non-contact testing can be realized outside. This work presents a novel, safe method for realizing hazardous gas detection.
