Considering extract-transform-load (ETL) as a complex and evolutionary process, development teams must conscientiously and rigorously create log strategies for retrieving the most value of the information that can be gathered from the events that occur through the ETL workflow. Efficient logging strategies must be structured so that metrics, logs, and alerts can, beyond their troubleshooting capabilities, provide insights about the system. This paper presents a configurable and flexible ETL component for creating logging mechanisms in ETL workflows. A pattern-oriented approach is followed as a way to abstract ETL activities and enable its mapping to physical primitives that can be interpreted by ETL commercial tools.

At present, organizational culture has a leading position in the enterprise management system. The purpose of this study is to improve the methodology for assessing the development of organizational culture of enterprises and its testing on the example of Ukrainian enterprises in the provision of transport, consulting and banking services. As a result of the research, a questionnaire was made of 24 statements concerning the peculiarities of the organizational culture of enterprises, and on this basis an analysis and evaluation of the organizational culture was carried out. The reliability of the survey results was calculated using the Alpha Cronbach coefficient and XYZ-analysis. The integrated method of estimation of development of organizational culture of the enterprises is offered. The testing of this methodology showed that the surveyed enterprises have an average level of development of organizational culture, since the values of the integral indicators are in the range of 0.5–0.75. Based on the mentioned above, it is essential to propose priority directions to improve the management of enterprises’ organizational culture development: the application of a customer-oriented approach to the formation of organizational culture, based on the customer focus, complemented by the cross-functional interaction of company human resources in the decision-making process; development and realization: the mechanism of the strategic management of the enterprise organizational culture development; marketing strategy of the enterprise organizational culture development; organizational and economic mechanism for enterprise organizational culture development managing; the complex of measures for the digital transformation of enterprises organizational culture, which includes: use of employee-driven management, that is, an HR oriented approach to management – continuous employees training and skills development halves the time of a new product launching on the market; implementation of HRmaps the next generation modular platform for HR management – a comprehensive solution for the HR processes automation, which consists of 4 modules and the HR portal (personnel assessment; recruitment and adaptation; planning and career; training and development); HR digital upgrade, which is based on the introduction of a digital cloud platform providing a digital format for all personnel processes (up to 90% automation), which allows monitoring and company development. The practical value of the study is that the proposed methodical approach can be used in the activities of enterprises in assessing the level of development of their organizational culture. Keywords enterprise, organizational culture, Denison’s methodology, integrated estimation methodology, level of development of organizational culture, approbation, profile of organizational culture.

The future of enterprises depends among other things also on its rate of innovation. Particularly for the development of product ideas the innovation potential of living nature is used hardly or insufficiently during the construction process. Development teams orient themselves still too little at the evolution regularities and structure principles of biological systems. Orienting at the regularities of the evolution of biological systems as well as at the efficient principles of operation, structure and organization of living nature could supply various suggestions for new product ideas. For this reason the author of this contribution conceived a construction bionics, which helps the development engineer to use living nature systematically and purposefully as source of inspiration.

The use of transmission electron microscopy (TEM) to support process development of advanced microelectronic devices is often challenged by a large amount of samples submitted from wafer fabrication areas and specific-spot analysis. Improving the TEM sample preparation techniques for a fast turnaround time is critical in order to provide a timely support for customers and improve the utilization of TEM. For the specific-area sample preparation, a technique which can be easily prepared with the least amount of effort is preferred. For these reasons, we have developed several techniques which have greatly facilitated the TEM sample preparation.For specific-area analysis, the use of a copper grid with a small hole is found to be very useful. With this small-hole grid technique, TEM sample preparation can be proceeded by well-established conventional methods. The sample is first polished to the area of interest, which is then carefully positioned inside the hole. This polished side is placed against the grid by epoxy Fig. 1 is an optical image of a TEM cross-section after dimpling to light transmission.

Recently, the use of refractory metal silicides as low resistivity, high temperature and high oxidation resistance gate materials in large scale integrated circuits (LSI) has become an important approach in advanced MOS process development (1). This research is a systematic study on the structure and properties of molybdenum silicide thin film and its applicability to high performance LSI fabrication.
