Exact Definition

Since the emergence of digital hydraulic technology, it has achieved good results in intelligence, integration, energy saving, etc. After decades of development, and it has also attracted wide attention in the industry. However, for many years, the definition of digital hydraulic technology has differed between researchers, and there is no uniform definition. Such a situation affects the development of it to a certain extent. Therefore, this paper gives the exact definition of digital hydraulic technology based on a large number of researches on it. At the same time, the paper analyzes the research status and developmental process of the such a technology, and we forecast the development trend of it.

The concept of context is a cornerstone of a large part of social science research, particularly in organization and management studies, yet it has received little theoretical and methodological attention in lieu of its relevance. This book offers a definition of context as a theoretical construct, a discussion of the methodological implications of this, and a framework for how to reflect upon and operationalize the role of context in the different stages of a research process, from formulating research questions to analyzing and writing about results. The chapters presented here integrate lessons derived from various research experiences across the complex and dynamic field of health care. Contributors share their experiences with theorizing about and empirically studying significant organizational phenomena such as implementation of policy, organizational change, integration of care, patient involvement, human-technology interactions in practice, and the interplay between work environment and care outcomes in eldercare. These contributions exemplify how a nuanced approach to context might unfold in different fields, through different designs, methods, and analytical lenses. Relevant to researchers and practitioners, within both healthcare, organization and management studies, and the social sciences more broadly, this book leaves the reader with a practical framework from which to carry out contextual research and analysis and a gain deeper understanding of the significance of context in organizational life.

Key Parameter

Taking free shrinkage as the key parameter in evaluating cracking of concrete, the cracking properties of self-compacting concrete with strength grade of C35 and C50 were investigated based on ring and slab restraint tests. Meanwhile, the ultimate tensile strain of self-compacting concrete was studied by using flexural test. Experimental results show that the shrinkage of self-compacting concrete is lower than that of normal concrete. Self-compacting concrete cracks later than normal concrete with the same strength grade. Although the ultimate flexural tensile strains of self-compacting concrete in 7 d and 28 d are a little bit lower than that of the normal concrete, it can still be concluded from the research that the cracking property of self-compacting concrete can be greatly improved by using proper mix proportion.

Canning Industry

It is considered the essence of the terms of innovations and innovative activity of the canning industry enterprise, on example of enterprises of the Ukrainian Black Sea region. It is improved the classification of types of innovations and innovative processes for canning enterprises, by allocating relevant classification groups, that are actual in the aspect of modern scientific and practical approaches. The economic essence of the category of innovative susceptibility of enterprises is determined. According to the modern requirements and challenges that arise in the process of transformation of the national economic system it is determined the need of update of the theoretical basis for the study of innovation processes, and it is proved the necessity of formulation of the objective definitions and classifications of innovations, of the types of innovation activities that make key-point in the research process of the current realities of economic development. As a result of the research of various types and definitions of innovations, it is established that the most important for the analyzing process of innovations for enterprises in the canning industry are such classifications, which are based on the degree of participation in the production process (production and non-productive innovations: administrative, in other processes of internal management, in the processes of supply-sales, in circulation processes, financial services), on the functional purpose of innovations (production and technological, personnel, economic, logistic, marketing, financial, investment, infrastructure innovations). The definition of innovations for canning enterprises is given in the article, it is developed the classification of types of innovation for the canning enterprise that is oriented on objective features and distinguishes of the innovation process, which is actually carried out by domestic enterprises that allows to take into account the aspect of actuality.

Active introduction of digital technologies in all spheres of life is one of the main directions of state development as a whole and separate sphere of activity. The issue of using information technologies and systems during forensic examination is the subject of scientific research of many domestic and foreign scientists, but this sphere remains relevant. The introduction of digital technologies in forensic activities is one of the priority areas for the forensic science development at the present stage and has significant development potential. One of the areas of optimization and improvement of forensic activity is the development of methods to automate the formation of forensic experts and unify the description of the research process, identified features, justification and formulation of forensic conclusions, which requires legislative consolidation and regulation, analysis and definition of the subject area and development requirements and algorithms for the operation of the system interface. Unification and standardization of the content of forensic experts' opinions requires the development of common standards and an information system adopted by all subjects of forensic expertise, and meets the needs of practice. The development of an information system for forming an expert opinion and automatically forming an expert opinion will allow formalizing and unifying the description of research and results of forensic examinations, optimizing the time of forensic experts and potentially reducing the number of logical, typographical and technical errors, and simplifying quality control of forensic examinations. The proposed system will not only automate the technical work of registration of research results carried out during forensic examinations, but will also contain research algorithms, which will be stored in the form of data on already conducted research of similar objects (list and sequence of operations, identified features and their parameters).
