Complex Event Processing (CEP), which can identify patterns of interest from a large number of continuous data steam, is becoming more and more popular in manufacturing process monitoring. CEP rules are specified manually by domain expert, which is a limiting factor for its application in manufacturing enterprises. How to analysis historical data and automatically generate CEP rules is becoming a challenge research. This paper proposed a model of autoCEP for online monitoring in product manufacturing, which can automatically generate CEP rules based on association rules mining in key processes. First, the key quality factors in manufacturing process were extracted by grey entropy correlation analysis. Then, association rules mining method based on product process constraints was used to find the association rules between key factors and product quality. At last, the extracted rules are algorithmically transformed into CEP rules. The experimental results show the effectiveness and practicability of the proposed method.

The article is devoted to the topical problem of neonatology and pediatric neurology — the diagnosis and treatment of seizures in newborns and young children. The work presents an algorithm for the diagnosis and treatment of epileptic seizures in children. It is indicated that the therapeutic effect of most antiepileptic drugs consists of modulation of voltage-gated and ligand-gated channels of membranes of neurons of the cerebral cortex, enhancement of inhibitory synaptic transmission or inhibition of activating synaptic transmission. The issues of the pharmacokinetics and pharmacodynamics of antiepileptic drugs are considered, taking into account the age characteristics of the child's body, in particular, newborns and early age children. The problems of drug interaction were discussed. The properties of individual antiepileptic drugs, which are used in newborns and young children, are considered. Emphasized are «polar» differences in the work of phenobarbital, which depend on the stage of epileptogenesis, namely: suppression of epileptiform activity at the early stage of epileptogenesis and its enhancement in the already formed epileptic focus (epileptic system). The literature data on the differentiated treatment of certain epileptic syndromes are presented. The issues on the prospects for the treatment of genetically determined diseases, which are accompanied by seizures associated with metabolic disorders, are considered. The modern high-tech methods of treatment of these diseases are noted. The role of diet therapy, co-factor therapy in the treatment of hereditary metabolic disorders, in particular, the ketogenic diet as a method of alternative treatment for drug-resistant epilepsy in children, is shown. No conflict of interest was declared by the authors. Key words: newborn, epilepsy, epileptic encephalopathy, treatment, antiepileptic drugs, review.

Ischemic stroke is still a very common disease with quite serious consequences. Modern medicine considers in this regard its main task in the curation of such patients, the maximum possible restoration of the functions of the affected brain and the volume of its control over the body. Due to the rapid development of medicine associated with the emergence of innovative technologies in the field of rehabilitation, hardware methods of rehabilitation today have gone far ahead and have in their arsenal a lot of high-tech tools. For this purpose, a search is being made for means of increasing the activity of brain cells located in the affected area. Of particular importance in this regard are the methods of rehabilitation in the early recovery period after ischemic stroke using robotic methods of mechanotherapy, one of which is the use of the Lokomat system. Among them, a prominent place is occupied by the walking training system - Lokomat, consisting of robotic orthoses and a body support device, which are combined with a treadmill. Information about the successful use of Lokomat during the rehabilitation of patients with movement disorders is still scattered, and this required their generalization and understanding. The main advantage of this system is the ability to effectively control and ensure high intensity, repeatability (reproducibility) and purposefulness of the trained movements. The convincing advantages of automated training on the Lokomat system compared to traditional rehabilitation in terms of various clinical indicators in patients with post-stroke hemiparesis have been identified. It was shown that in patients trained on the Lokomat system, a single support on the paretic leg intensified, which contributed to a more symmetrical gait. This system is more than other devices and technologies designed for learning to walk, in line with the modern approach to the restoration of impaired motor functions. The inclusion of training sessions on the Lokomat robotic system in the comprehensive treatment of patients with post-stroke hemiparesis leads to a marked improvement in movement skills. This is associated with a pronounced restructuring against the background of its use of the motor stereotype of walking, which makes it possible to increase the effectiveness of recreational activities in post-stroke patients.

This chapter underscores the importance of timing by focusing on the effect of pre-existing standards and regulations on the innovation and diffusion of new high-tech product innovations. The effect is assessed in terms of the time interval between the invention of a technological principle and the introduction of the first marketable product (development phase), and the successive time interval up to the start of large-scale industrial production and diffusion (adaptation phase). Fifty heterogeneous cases of new high-tech product innovations from 1850 onward are analysed. Results indicate that pre-existing standards and regulations significantly shorten the adaptation phase, an effect not found for the development phase. The shortening effect on the adaptation phase is particularly evident for more radical innovations and for innovations that are more interrelated with a larger technological system. This accelerating effect on the diffusion of innovations is highly relevant for innovation managers and policy makers alike.

Every finished product has gone through a series of transformations. The process begins when manufacturers purchase the raw materials that will be transformed into the components of the product. The parts are then supplied to a manufacturer, who assembles them into the finished product and ships the completed item to the consumer. The transformation process includes numerous activities (Levary, 2000). Among them are • Designing the product • Designing the manufacturing process • Determining which component parts should be produced in house and which should be purchased from suppliers • Forecasting customer demand • Contracting with external suppliers for raw materials or component parts • Purchasing raw materials or component parts from suppliers • Establishing distribution channels for raw materials and component parts from suppliers to manufacturer • Establishing of distribution channels to the suppliers of raw materials and component parts • Establishing distribution channels from the manufacturer to the wholesalers and from wholesalers to the final customers • Manufacturing the component parts • Transporting the component parts to the manufacturer of the final product • Manufacturing and assembling the final product • Transporting the final product to the wholesalers, retailers, and final customer Each individual activity generates various data items that must be stored, analyzed, protected, and transmitted to various units along a supply chain. A supply chain can be defined as a series of activities that are involved in the transformation of raw materials into a final product, which a customer then purchases (Levary, 2000). The flow of materials, component parts, and products is moving downstream (i.e., from the initial supply sources to the end customers). The flow of information regarding the demand for the product and orders to suppliers is moving upstream, while the flow of information regarding product availability, shipment schedules, and invoices is moving downstream. For each organization in the supply chain, its customer is the subsequent organization in the supply chain, and its subcontractor is the prior organization in the chain.
