The article presents the results of studies on the adjustment of cadastral value using a new factor-the probability of an emergency or natural disaster. A new term, emergency geospatial, has been introduced for the spatial definition of an emergency. The analysis of the legal regime of lands subject to emergency situations is carried out. Conclusions are drawn about the legal definition of the geospatial boundary of the emergency situation and the impact of emergencies on real estate. The characteristic of emergency situations, as well as the probability of their occurrence is given. The connection between the emergency situation and the cadastral value of real estate is shown. The dependence of the value of real estate on their location in the geospatial probable emergency. The technological scheme of determination of cadastral value of real estate objects in the zone of manifestation of an emergency situation is developed. A geoinformation project was carried out on the territory of the city of Novosibirsk. The most probable emergencies are taken into account. The map of zones of possible manifestation of emergency situations is made. The comparison of the cost of real estate in emergency zones, with objects analogues, located outside the emergency zone. The values of the correction factor for adjusting the cadastral value are proposed. The map of distribution of correction factors for adjustment of cadastral value of real estate objects in zones of possible manifestation of emergency situations is made. Work on the adjustment of the cadastral value of real estate located in the areas of possible manifestations of emergency situations is promising. First, the zones must be taken into account in modern urban policy and as much as possible to protect real estate and the population from the manifestation of emergency situations. Secondly, the reduction of cadastral value and taxes will allow owners to invest in insurance funds and insure real estate.

The article summarizes existing information about the current surface manifestations of the covered carbonate karst in Moscow city territory. The analysis of engineering-geological conditions of sinkholes area in the north-west of the city is performed. The confinement of the sinkholes to places of overlapping of different ages entrenched streams and sites of ancient karst disturbances is noted. The technogenic reasons for the activation of sinks in the middle of the 20th century are considered and it is shown that the main factor is the change in the hydrodynamic regime. The most significant emergency situations in the north-west of Moscow were investigated and measures for liquidating the consequences, whose cost along with the value of destroyed objects determines the magnitude of direct economic damage, are characterized. On the example of a concrete sinkhole, the dynamics of emergency situation development are traced. The estimation of design decisions used for preservation of buildings and constructions stability in the places of possible sinkholes formation is given. It is concluded that one of the most important tasks of studying the development territories of a covered carbonate karst is to identify areas where ancient and buried old sinkholes are present and to classify these areas as hazardous. Now in Moscow there is only one such district in the north-west with an area of about 11 km2, despite the fact that sinks arise regularly throughout the city area. A rather complete information has been collected on the collapses and subsidence for the period from the beginning of the 20th century to the present day and an attempt has been made to reveal the superficial manifestations of karst in other parts of the city similar in geological conditions to the north-western region. A retrospective analysis of the engineering-geological conditions of the sites of modern sinks development is made and the karst-suffusion genesis of several collapses in the central part of Moscow has been determined, which gives grounds to single out another hazardous region here.

Response System

The paper addresses the problem of increasing transportation safety due to usage of new possibilities provided by modern technologies. The proposed approach extends such systems as ERA-GLONASS and eCall via service network composition enabling not only transmitting additional information but also information fusion for defining required emergency means as well as planning for a whole emergency response operation. The main idea of the approach is to model the cyber physical human system components by sets of services representing them. The services are provided with the capability of self- contextualization to autonomously adapt their behaviors to the context of the car-driver system. The approach is illustrated via an accident emergency situation response scenario. “ERA-GLONASS” is the Russian state emergency response system for accidents, aimed at improving road safety and reducing the death rate from accidents by reducing the time for warning emergency services. In fact, this is a partially copied European e Call system with some differences in the data being transmitted and partly backward compatible with the European parent. The principle of the system is quite simple and logical: in the event of an accident, the module built into the car in fully automatic mode and without human intervention determines the severity of the accident, determines the vehicle’s location via GLONASS or GPS, establishes connection with the system infrastructure and in accordance with the protocol, transfers the necessary data on the accident (a certain distress signal). Having received the distress signal, the employee of the call center of the system operator should call the on-board device and find out what happened. If no one answers, send the received data to Sistema-112 and send it to the exact coordinates of the team of rescuers and doctors, and the last one to arrive at the place is given 20 minutes. And all this, I repeat, without the participation of a person: even if people caught in an accident will not be able to independently call emergency services, the data on the accident will still be transferred. In this work intended to add some information about applying system project in Uzbek Roads especially mountain regions like “Kamchik” pass. The Kamchik Pass is a high mountain pass at an elevation of 2.306 m above the sea level, located in the Qurama Mountains in eastern Uzbekistan and its length is about 88km.The road to reach the pass is asphalted, but there are rough sections where the asphalt has disappeared. It’s called A373. The old road over the pass was by passed by a tunnel built in 1999. On the horizon, the snow-capped peaks of the Fan Mountains come into view. The pass is located in the Fergana Valley between the Tashkent and Namangan Regions.

Flooding is a dangerous phenomenon, causing emergency situations and causing material damage, capable of damaging health, and even death of people. To reduce the risk and economic damage from flooding, it is necessary to forecast flooding areas. An effective method of forecasting emergency situations due to flooding is the method of remote sensing of the Earth with integration into geoinformation systems. With the help of satellite imagery, a model of flooding was determined based on the example of Tavda, the Sverdlovsk Region. Space images are loaded into the geoinformation system and on their basis a series of thematic layers is created, which contains information about the zones of possible flooding at given water level marks. The determination of the area of flooding is based on the calculation of the availability of maximum water levels at hydrological stations. According to the calculated security data, for each hydrological post, flood zones are constructed by interpolation between pre-calculated flood zones of standard security. The results of the work can be used by the Main Directorate of the Ministry for Emergency Situations of Russia for the Sverdlovsk Region.

<p>Deaf or hearing loss is a condition of inability to hear something, either totally or partially. Hearing loss greatly affects the life of a person in communicating with the people around him. Deaf people will be very difficult when in a medical emergency, this is because the medical emergency situation requires fast action.</p><p>          The Healthy Phone application is a mobile medical emergency call application that can help people with hearing impaired when in emergency situations. With the Healthy Phone application, the user only needs to select an icon that suits the situation encountered in touchscreen mobile device then the message will be sent to the nearest hospital.</p>                To search for icons corresponding to emergencies, the User Centered Design (UCD) method is used. This application is very helpful for deaf people because this application does not require audio communication and user location is also sent automatically to the nearest hospital. The results were analyzed using four emergency event scenarios with a total score of 87% and an average user time of less than 0:42 sec indicating that the study was successful in designing a mobile medical emergency call application according to user requirements.

Real Practice

It is proposed to use the new approach to assessing quantitative risk indicators. This approach allows to consider the temporal non-stationarity of the number of processes, including the development of an accident and the spatial movements of people. The greatest uncertainty in the risk analysis with an explosive and fire hazard component is not the frequency of initiating events used, but, for example, data on the probability of ignition. The range of variation of this probability is about two orders of magnitude (relatively speaking, from 1 % to 100 %), and the criteria and factors that determine the choice of this value are not always clearly defined. The paper proposes an approach that considers the probability of ignition as a dependence on the time that passed after the start of emergency depressurization. Knowing this dependence, it is possible to consider several scenarios with different ignition time after the start of the release and assign certain consequences and probabilities to each scenario. Moreover, it is possible for each single scenario on a specific piece of equipment (pipeline section) to obtain non-stationary, namely time-varying potential risk fields. The example of an accident on the oil pipeline is considered, the risk indicators of such an accident are calculated, it is shown that the risks can change over time, namely they are non-stationary characteristics. Further, this fact is transformed into the development of theoretical foundations for quantitative risk assessment, considering the non-stationarity of various processes occurring during emergency situations arising during the operation of equipment, individual behavior of people and changes in external conditions. The results obtained show the importance of considering the changes that occur during an emergency on the main oil and product pipelines. It is concluded that the proposed approach allows to reduce the conservatism of assessments provided by traditional methods. In real practice this approach can reasonably reduce the risk indicators by several times, sometimes by orders of magnitude.

The main disadvantages of the existing methods of managing the current state of technical systems are revealed. A non-standard approach is proposed for managing the functionality of the system in emergency situations. The character of the dynamics of the recovery processes of the technical system is determined as its state approaches the emergency one on the basis of the recommendations of the theory of self-organized criticality (SOC). The physical criteria for assessing the current state of the technical system are revealed. The rationale for using the physical indicator of the functional destabilization of the system is given. The signs of the pre-emergency state of the technical system are considered. A grapho-analytical model for the development of an emergency situation has been developed. The fact of the inevitable increase in the entropy of the system upon its transition to an emergency state is established. Structuring of the system development process in an emergency situation is carried out in three stages. The methodology for estimating the pre-emergency state of complex open systems is presented. The advantages of the proposed approach to managing the state of technical systems in comparison with traditional ones are established.
