INTERNAL PR AS PART OF CORPORATE CULTURE

The identification of mechanisms for the implementation of public relations and the selection of effective internal PR tools can affect the organization’s management. The main objective of internal PR is to stabilize the workforce and increase employee satisfaction. The possibilities of internal PR in the formation and maintenance of corporate culture have been investigated in the article. The indicators of labor assessment presented not only help determine the level of professionalism of the employee, but also demonstrate his personalized labor achievements to the whole team. The motivation of the participants of the labor process to the awareness of the importance of the implementation of the collective tasks has a beneficial effect on the formation of corporate culture. Monitoring of events and internal PR tools will allow you to adjust the formation of corporate culture and provide a high level of management at the enterprise.

Data-Analytics Modeling of Electrical Impedance Measurements for Cell Culture Monitoring

High-throughput data analysis challenges in laboratory automation and lab-on-a-chip devices’ applications are continuously increasing. In cell culture monitoring, specifically, the electrical cell-substrate impedance sensing technique (ECIS), has been extensively used for a wide variety of applications. One of the main drawbacks of ECIS is the need for implementing complex electrical models to decode the electrical performance of the full system composed by the electrodes, medium, and cells. In this work we present a new approach for the analysis of data and the prediction of a specific biological parameter, the fill-factor of a cell culture, based on a polynomial regression, data-analytic model. The method was successfully applied to a specific ECIS circuit and two different cell cultures, N2A (a mouse neuroblastoma cell line) and myoblasts. The data-analytic modeling approach can be used in the decoding of electrical impedance measurements of different cell lines, provided a representative volume of data from the cell culture growth is available, sorting out the difficulties traditionally found in the implementation of electrical models. This can be of particular importance for the design of control algorithms for cell cultures in tissue engineering protocols, and labs-on-a-chip and wearable devices applications.
