The application of churn prevention represents an important step for mobile communication

companies aiming at increasing customer loyalty. In a machine learning perspective,

Customer Value Management departments require automated methods and processes to

create marketing campaigns able to identify the most appropriate churn prevention approach.

Moving towards a big data-driven environment, a deeper understanding of data

provided by churn processes and client operations is needed. In this context, a procedure

aiming at reducing the number of churners by planning a customized marketing campaign

is deployed through a data-driven approach. Decision Tree methodology is applied to drow

up a list of clients with churn propensity: in this way, customer analysis is detailed, as well

as the development of a marketing campaign, integrating the individual churn model with

viral churn perspective. The first step of the proposed procedure requires the evaluation of

churn probability for each customer, based on the influence of his social links. Then, the

customer profiling is performed considering (a) individual variables, (b) variables describing

customer-company interactions, (c) external variables. The main contribution of this work

is the development of a versatile procedure for viral churn prevention, applying Decision

Tree techniques in the telecommunication sector, and integrating a direct campaign from

the Customer Value Management marketing department to each customer with significant

churn risk. A case study of a mobile communication company is also presented to explain

the proposed procedure, as well as to analyze its real performance and results.

Celem tego studium jest odpowiedź na pytanie, czy informatyka stanowi dziedzinę czy tylko dyscyplinę wiedzy. Przeprowadzono analizę problemów informatycznych, z której wynika, że informatykę w Polsce należy traktować jako dziedzinę. Podkreślono, że angielski termin computer science stanowi tylko jedną ze specjalizacji informatyki, słowo „informatyka” zaś powinno być kojarzone znacznie szerzej niż nawet information technology (IT w USA i ICT w Europie prócz Francji, gdzie stosuje się termin l’informatique). Jak pokazano, wąskie traktowanie informatyki utrudnia pełny jej rozwój. W praktyce oznacza to ograniczenie w podejmowaniu ambitnych zadań oraz większe koszty jej rozwoju. Społeczne implikacje potwierdzają, że mimo wielu zdolnych informatyków Polska nie doczekała się (poza grami komputerowymi) własnych trwałych innowacyjnych rozwiązań informatycznych. Stąd wynika więc potrzeba opracowania krajowej strategii informatyzacji, gdyż sama strategia cyfryzacji nie wystarcza do zapewnienia sukcesów.

The article is a sort of advanced publication workshop prepared by a group of M.Sc. students in ICT participating in the course on QIT. The idea behind the publishing exercise is to try to link, if possible, individual own work just under realization for the thesis with new unique possibilities offered by the QIT. Each chapter is written by a single author defining concisely her/his research interest in the classical ICT field and trying to find possible correlations with respective abruptly developing branches of the QIT. The chapter texts are somehow moderated by the tutor but are exclusively authored by young researchers. The aim was to present their views on the possible development directions of particular subfields of QIT, if not fully mature, but still based on their own ideas, research and dreams.

This article discusses four fields of study with the potential to revolutionize our understanding and interaction with biological systems: quantum biophotonics, molecular and supramolecular bioelectronics, quantum-based approaches in gaming, and nano-biophotonics. Quantum biophotonics uses photonics, biochemistry, biophysics, and quantum information technologies to study biological systems at the sub-nanoscale level. Molecular and supramolecular bioelectronics aim to develop biosensors for medical diagnosis, environmental monitoring, and food safety by designing materials and devices that interface with biological systems at the molecular level. Quantum-based approaches in gaming improve modeling of complex systems, while nanomedicine enhances disease diagnosis, treatment, and prevention using nanoscale devices and sensors developed with quantum biophotonics. Lastly, nano-biophotonics studies cellular structures and functions with unprecedented resolution.

Technological progress is the driving force behind industrial development. It is a multidimensional and multi-level phenomenon. In this article we focus on its three manifestations: information and communication technologies (ICT), Industry 4.0 and agile manufacturing. The aim of this article is to analyse the relationship between these constructs as they are undoubtedly interrelated. ICT plays a key role, but it is not a goal itself. They are a prerequisite for the implementation of Industry 4.0, but together with it they serve to achieve agility by the manufacturing system and, as a result, achieve a competitive advantage by companies operating in turbulent and unpredictable environment. The literature findings in this paper are part of a broader study conducted on the impact of ICT on agility of SMEs operating in India. Therefore, we include also subsections showing the level of this relationship in Indian SMEs.

The aim of the paper is to show how graduated engineering students in classical ICT view practically the advent of the QIT. The students do their theses in El.Eng. and ICT and were asked how to implement now or in the future the QIT in their current or future work. Most of them have strictly defined research topics and in some cases the realization stage is advanced. Thus, most of the potential QIT application areas are defined and quite narrow. In such a case, the issue to be considered is the incorporation of QIT components and interfaces into the existing ICT infrastructure, software and hardware alike, and propose a solution as a reasonable functional hybrid system. The QIT components or circuits are not standalone in most cases, they should be somehow incorporated into existing environment, with a measurable added value. Not an easy task indeed. We have to excuse the students if the proposed solutions are not ripe enough. The exercise was proposed as an on-purpose publication workshop, related strictly to the fast and fascinating development of the QIT. The paper is a continuation of publishing exercises with previous groups of students participating in QIT lectures.

The article is a result of a complementary advanced publication workshop accompanying the curriculum course exercises for PhD students, on the role of ICT in the research work of a scientist. To fulfill the extended course requirements the participants decided to write relevant paper, if possible, related to their individual research endeavors and their relations to the digital world. The paper consists of a collection of short chapters written by young researchers. They express their own views, based on early research experience, relevant generally to the inclusion of critical digital age components in their theses. The chapters are only moderately consulted by the tutor in the direction of finding a common denominator related to social sciences.

This paper is written by a group of Ph.D. students pursuing their work in different areas of ICT, outside the direct area of Information Quantum Technologies IQT. An ambitious task was undertaken to research, by each co-author, a potential practical influence of the current IQT development on their current work. The research of co-authors span the following areas of ICT: CMOS for IQT, QEC, quantum time series forecasting, IQT in biomedicine. The intention of the authors is to show how quickly the quantum techniques can penetrate in the nearest future other, i.e. their own, areas of ICT.
