    Opis:
    Effects of the stored dust-like zinc and iron containing wastes of the mining and processing industry consist of the loss of valuable components and environmental pollution. Thus, the goals of the research were to analyse ecological conditions under the technogenic impact at the waste storage site and to study transformations of the stored dust-like zinc and iron containing wastes in the active supergene zone. Materials are based on the physical laboratory-modelled infiltration of the atmospheric precipitation waters through the zinc and iron containing wastes. Methods include systematically- structured analysis of wastes and disposal site and laboratory techniques (X-ray fluorescence and atomic emission spectrometry). On the basis of laboratory research and field observations of the environmental components in the impact area of the storage of dust-like zinc and iron containing wastes, the article describes regularities of formation of hydrogeochemical halos of contamination by heavy metals and iron. The results also include the description of changes in physico-chemical groundwater composition under the storage area.

    Opis:
    A hardware-software system has been implemented to monitor the environmental state (EnvState) at the site of railway (RY) accidents and disasters. The proposed hardware-software system consists of several main components. The first software component, based on the queueing theory (QT), simulates the workload of emergency response units at the RY accident site. It also interacts with a central data processing server and information collection devices. A transmitter for these devices was built on the ATmega328 microcontroller. The hardware part of the environmental monitoring system at the RY accident site is also based on the ATmega328 microcontroller. In the hardwaresoftware system for monitoring the EnvState at the RY accident site, the data processing server receives information via the MQTT protocol from all devices about the state of each sensor and the device's location at the RY accident or disaster site, accompanied by EnvState contamination. All data is periodically recorded in a database on the server in the appropriate format with timestamps. The obtained information can then be used by specialists from the emergency response headquarters.

    Opis:
    Ecological Momentary Assessment (EMA) is a method comprising repeated self-reports in the participant’s natural environment which can be used to evaluate hearing aids in real life. Social situations are particularly important for such evaluations as these are situations where listening is critical and often difficult. However, as shown for a German subject sample by Schinkel-Bielefeld et al., these are also situations where test participants may skip a questionnaire as it could be perceived as impolite to answer a questionnaire on the smartphone. This leads to the underrepresentation of speech in noise situations in EMA assessment. However, the acceptance of smartphone use in public depends on cultural norms and may be larger in Asian countries. Repeating the previous study with 10 Singaporean hearing-impaired test participants, we observed that self-reports are often answered with some delay but not skipped in social situations. Also, contrary to the German study, speech in noise situations were not underrepresented in questionnaires in the Singapore study.

    Еnvironmental and Socio-Demographic Consequences of the Chornobyl Nuclear Power Plant Accident: A Historical Retrospective after 36 Years

    Opis:
    The accident at the Chornobyl Nuclear Power Plant was one of the largest in human history. It is often referred to as a global event because its effects were felt not only by Ukrainians but also by the populations of Belarus, Russia, Central Europe, the Balkans and the Scandinavian Peninsula. 2022 marked the 36th anniversary of this terrible occurrence, when the history of Ukraine in the late twentieth century was divided into two parts: before the tragedy of 26 April 1986, and after it. Today, it is important for Ukrainian society not only to recognise the significance of the catastrophe and remember its victims but also to find ways to overcome its grave consequences. This requires comprehensive research useful for developing new approaches to minimising the environmental and socio-demographic problems caused by the Chornobyl tragedy. Thus, this research has practical scientific, humanitarian and socio-political significance. The novelty of the obtained results lies in the study’s critical rethinking of the achievements of predecessors and its analysis of historical sources concerning the environmental and socio-demographic consequences of the accident at the Chornobyl Nuclear Power Plant as they manifested from 1986 to 2022. The methodological basis of the work is empirical cognition. The use of logical-analytical methods of grouping and typology allows us to classify homogeneous events and coherently present the material of the article. The study additionally uses comparative judgment, historical-statistical and problem-chronological methods. The principles of objectivity and impartiality also play an important role in the work. The purpose of the study is to investigate the consequences of the Chornobyl Nuclear Power Plant accident on the environmental and socio-demographic aspects of the population of Ukraine from 1986 to 2022 based on the identified set of sources. From a historical perspective, the level of pollution in the territories of Ukraine is traced, the demographic situation is monitored, and parallels are drawn between the Chornobyl disaster and the increase in incurable diseases and mortality. In conclusion, the authors note that although 36 years have passed, the echo of this catastrophe remains tangible for the population of Ukraine. Several issues still must be solved. The first is the return to life, namely, the safe living and management of areas that have been exposed to radiation contamination, as well as the continuation of work aimed at restoring agricultural soils. Second, purposeful work must be conducted by the state to minimise social and demographic problems resulting from the Chornobyl catastrophe. In our opinion, the government should increase expenditures aimed at providing quality medical services to the population of Ukraine, as well as conduct constant monitoring of the health of those people who are at high risk in order to better detect diseases in their early stages. These groups of people include liquidators of the consequences of the accident and migrants. Such measures can stabilise the demographic situation by increasing birth rates and reducing mortality, as well as improve the health and living standards of the population of Ukraine.
