Assessment and Management of the State of Health Based on Rasch Models

Predictive Modeling of Occupational Safety Risks Associated with Railway Workers Using Hybrid Fuzzy Modeling Approach

“…A study of the working conditions of workers of locomotive crews is organized and the production risk factors leading to the appearance and development of occupational diseases, as well as provoking other classes of diseases due to the individual characteristics of the organism, are determined. Risk factors should be grouped taking into account the MSHFDR recommendation, within the framework of which methods for the synthesis of decision rules for assessing health status by the group of ergonomic, [10,[19][20][21] environmental [12,13] and individual [11,22] risk factors have been developed and tested. Separately, the methods of synthesis of decision rules for hazardous industrial substances [13,18,23] and electromagnetic radiation [10,14,23] have been tested quite well, depending on the intensity and time of exposure.…”

“…The last formula requires the availability of appropriate software and hardware, a description of which can be found in [28- [31][32][33] . In accordance with the recommendations [22] , it is advisable to assess the level of long-term YP -YPH using a temporary correction factor γ p (t) defined as a functional dependence on the length of service under the action of industrial electromagnetic fields. Y P H = γ p (t).Y P Such a risk factor as chronic fatigue is determined similarly to the YP level in three components.…”

“…An important role in the emergence and development of occupational and concomitant diseases is played not by current, but by chronic psycho-emotional stress Y P H and chronic fatigue Y U H methods of calculation of which are given in [19][20][21][22]. For these two indicators, the confidence in, taking into account the results described in works [11,22,27,30,34] , is determined through the corresponding membership functions:…”

Optimization of management of patients with critical lower limb ischemia, allowing for risk of gangrene

“…Степень соответствия этих препаратов латентной переменной "эффективность лечения" проверялась пакетом RUMM 2020 [7,15].…”

“…Не существует также четко установленных границ между различными стадиями развития гангрены, что не позволяет получить надежно работающие прогностические и классификационные аналитические модели без привлечения знаний высококвалифицированных экспертов [5,[7][8][9]. В работах [5,7,[9][10][11][12][13] показано, что при таких условиях целесообразно использовать технологию мягких вычислений, включая нечеткую логику принятия решений [5,6,[12][13][14] и теорию измерения латентных переменных [7,15].…”
