Увеличение объёмов баз данных при создании и использовании изделий морской техники (МТ) диктует необходимость снижения размерности этих баз с одновременным повышением достоверности и точности получаемых оценок. Многомерные свойства вновь создаваемых наукоёмких изделий МТ проявляются в сферах, отстоящих от момента принятия решений по их созданию, на значительный временной период (до года и более). Указанное обстоятельство диктует необходимость прогноза всех видов затрат, начиная с ранних этапов разработки технического задания, составления предконтрактного проекта, технической подготовки производства, в условиях неполной известности информации. Вот почему для получения оценок предлагается использовать только известные определяющие параметры. Математические модели оценки абсолютных удельных показателей, отнесённых к значению определяющих параметров (во времени) наиболее полно отвечают решению указанных проблем и доказали свою состоятельность. Научно-методические подходы, изложенные в статье, предлагаются к использованию в отечественном судостроении, замыкая «обратную связь» учёта требований системы производства и использования изделий МТ при принятии решений по их созданию. The increase in the volume of databases for the creation and use of marine equipment products (MT) dictates the need to reduce the dimension of these databases while increasing the reliability and accuracy of the estimates obtained. The multidimensional properties of newly created high-tech MT products are manifested in areas that are separated from the moment of making decisions on their creation for a significant time period (up to a year or more). This circumstance dictates the need to forecast all types of costs, starting from the early stages of the development of the terms of reference, drawing up a pre-contract project, technical preparation of production, in conditions of incomplete information. That is why it is proposed to use only known defining parameters to obtain estimates. Mathematical models for estimating absolute specific indicators related to the value of determining parameters (in time) most fully meet the solution of these problems and have proved their viability. The scientific and methodological approaches outlined in the article are proposed for use in domestic shipbuilding, closing the "feedback" of taking into account the requirements of the production system and the use of MT products when making decisions on their creation.

The Moment

Decision makers face a very large number of heterogeneous contextual cues; some of these pieces are always relevant (time period, unpredicted event, etc.), but others are only used in some cases (an accompanying person in the car, etc.). Actors then must deal with a set of heterogeneous and incomplete information on the problem-solving state to make their decisions. As a consequence, a variety of strategies are observed, including those involving an actor to another one, but also for the same actor according to the moment. It is not obvious how to get a comprehensive view of the mental representations at work in a person’s brain during many human tasks, and the argumentation rather than the explicit decision proposal is crucial (Forslund, 1995): It is better to store advantages and disadvantages rather than the final decisions for representing decision making.

The rapid acceleration of scientific and technological progress, which started at the beginning of the 21st century, has become a decisive factor in influencing the global economy. Who will lead the global innovation race? This problem is especially relevant in the field of artificial intelligence (AI). At the moment, the United States and China are the main participants in the battle for dominance in this area. The author assesses Chinas innovative potential in the field of AI and identifies its achievements in this area. Based on the statistics provided, Chinas AI leadership has reached a critical point. China is confidently leading the new fundamental research of artificial intelligence, forming its theoretical base and applied research and development, which will contribute to the creation of new high-tech innovative products and services. However, in terms of the number and quality of AI specialists (AI Talents) and the number of companies engaged in AI, China is still lagging behind its main rival, namely the United States. The author proved that, despite the obvious successes of China, the United States still has an equal lead in the global innovation race.

The most common cause of neurological disability in childhood is cerebral palsy. The objectives of the treatment of children with cerebral palsy are the acquisition and maintenance of new motor skills; prevention of the development of contractures and other secondary orthopedic complications; decrease in the level of pain; improving the level of childcare. At the same time, the provision of treatment and rehabilitation assistance to children with cerebral palsy requires an integrated, systematic approach. The article describes the route of rehabilitation of children with cerebral palsy in the Chuvash Republic from the moment of diagnosis until reaching the age of 18. The study was carried out on the basis of an analysis of data from the regional register of children with cerebral palsy at all stages of treatment and rehabilitation (habilitation). The first stage includes the identification of risk groups for cerebral palsy, conservative, surgical specialized medical care. The register of children with cerebral palsy made it possible to keep records of patients at the stages of treatment and rehabilitation with an assessment of the results. At the second stage, high-tech conservative and surgical treatment is carried out. After operations, patients are sent for rehabilitation to a 24-hour hospital or to a Rehabilitation Center for Children (over 3 years, 1.5 thousand children were treated, 25.7% after operations). The third stage is organized at the outpatient clinic level and in specialized sanatoriums. For 20142018 the coverage of children with cerebral palsy with conservative treatment increased 1.9 times, with botulinum therapy 2.6 times, the proportion of those who received surgery decreased to 22.4%. 92.7% of patients of the Register are covered by conservative treatment. 33.3% of operated children were referred for sanatorium-resort treatment. The control section of the rehabilitation results showed an increase in the proportion of children with improved gait quality, the ability to stand independently, walk (with support), and an increase in the average level of physical activity. A multi-level system of interagency interaction in the provision of treatment and rehabilitation assistance to children with cerebral palsy in Chuvash Republic made it possible to ensure a sufficient amount of basic and availability of highly qualified medical care, effective management and control of the stages of rehabilitation.

In this paper article the authors point out the importance of actions aimed at reducing waste, increasing productivity and reducing costs in the supply chain, which will ensure the development of coordination as an emergent function of the supply chain and contribute to the formation of responsibility to internal stakeholders; they also note the difference between logistics and supply chain management (SCM), which, primarily, is that logistics usually refers to the activities taking place within one organization, and supply chains belong to the network of companies working together and coordinate their actions to product supply to the market. The authors point out that the development of partnership in supply chains makes it possible to perform collaborative planning on a common information base, collective management of stocks, risks and all this provides reasons to coordinate activities in the supply chain, i.e. the dependence of «exit» on «entry» becomes homogeneous. Particular attention is paid to the ways of improvement the supply chain functioning, which is proposed to carry out at three levels. The highest level includes the processes taking place throughout the supply chain, and concerns the relationship between all participants [10]. At the operational level (the second level), the constraint theory recommends to use the LPS (Logical Product Structure) method. At the current actions level (the third level) TOC proposes to use the concept of management of the production system DBR (English: Drum – Buffer – Rope), the application of which enables to increase the capacity of the production system. In order to identify the area of necessary changes, the authors propose to build a detailed flowchart of processes, actions and functions from receiving the order from the customer (either external or internal) up to the moment of order fulfilment and delivery to the customer, which makes it possible to analyze sequentially the system operation in the current time and identify the areas of necessary changes, as well as to increase the level of meeting the customer needs, ensuring the efficiency of material and information flows, strengthening the manufacturer status in the market.

There are several methodological approaches to model floodplains. The selection of the appropriate methodology is a matter of the required results and is very dependent on data availability. In fact, data availability is the crucial parameter especially when working in ungauged basins or ephemeral streams. The goal of this chapter is to evaluate methodologies used to floodplain modeling in small watersheds. An overview of the principal models used in floodplain modeling is presented here in terms of their relative advantages as compared to each other. The chapter provides the results obtained with different models applied to a small watershed situated in the Romania and concludes with a discussion about the various recommendations and solutions on flood modeling methodology.

Cardiac Output Measurements

Studies were performed on dogs to determine the constancy of the cardiac output during a 4-hour period beginning from the moment the animal was anesthetized. The cardiac output fell to varying quantities during the first hour but finally became stabilized at approximately 50–75% of the values obtained within the first 2–3 minutes following induction. Considerable variability in this response among different animals was noted. Similar studies on other animals, beginning approximately 1 hour following induction, indicated a similar pattern, i.e. that relatively stable cardiac outputs could be anticipated after this time period.

Abstract This study explores how firms manage the entire life cycle of innovation projects based on the framework of harvesting and planting innovation. While harvesting innovation seeks new products in the expectation of financial performance in the short term, planting innovation pursues creating value over a long time period. Without proper management of the process of planting and harvesting innovation, firms with limited resources may not be successful in launching innovative new products to seize a momentum in high tech industries. To examine this issue, the case of Samsung Electronics (SE), now an electronics giant originated from a former developing country, is analyzed. SE has shown to effectively utilize co-innovation to maintain numerous planting and harvesting innovation projects. Both researchers and practitioners would be interested in learning about how SE shared risks of innovation investment with external partners at the early stage of innovation cycles.
