The paper presents a photovoltaic system auto sizing algorithm with irradiance and shading calculation, which uses the photovoltaic geographical information system database. This calculation step is a very labor intensive task, which require a lot of iterative design time to find the optimum alternative. Based on measurement data, monthly irradiance correction matrixes are simulated to completely describe the yearly irradiance loss caused by shading of the nearby objects. As result, a function between the shaded area and the yearly energy loss can be obtained. Furthermore, photovoltaic modules can be auto-allocated on a given area according to the boundary conditions. Taking into consideration the photovoltaic installers’ pricing system, a complete photovoltaic auto-sizing algorithm can be presented, which greatly reduces the time spent on quotation writing. This paper also includes a battery energy storage sizing algorithm according to the given economic conditions, which extends the capability of the photovoltaic system auto-sizing algorithm.

Összefoglaló. A COVID-19 járvány rámutatott arra, hogy az egészségügy kiemelt nemzetbiztonsági terület. Az egészségbiztonsági kockázati tényezőkkel szemben ellenálló egészségügyi rendszerek adattudományi innováció nélkül nem képzelhetők el. A közlemény két esettanulmányon keresztül mutatja be, hogy a nagy, működés során generálódó adatbázisok elemzése hogyan segítheti a járványokkal szembeni védekezést. A mobilcella információk elemzése a leghatékonyabb eszköz a tömeges népességmozgások nyomon követésére, így a vesztegzár intézkedések hatásának döntéstámogatási célú vizsgálatára, az oltásellenes közösségimédia-aktivitás hálózatelemzése pedig segíti az immunizációs kampányok tervezését és megvalósítását. Tanulmányunkban amellett érvelünk, hogy az egészségügy információ- és kommunikációtechnológia fejlődésére építő digitalizációja a kulcsa egy környezeti változásokkal megbirkózni képes egészségügy kialakításának.

Summary. The COVID-19 pandemic has shown that health and health care should be considered a top priority area of national security. Health security risks can only be addressed with resilient health systems, which are not possible to be established without innovation in health data science. This publication introduces two examples to illustrate this point, both in the field of the management of epidemics. The first case provides a summary of our previous publication about how mobile phone Call Detail Records can be used to trace population movement to evaluate the effectiveness of movement restriction measures, such as the lock down, which was implemented in Hungary during the first phase of the COVID-19 pandemic. Our analysis shows that the collation and processing of Call Detail Records is an effective and inexpensive method to monitor mass population movement, and complements well the GPS-based smartphone method, which is more suitable for contact tracing and controlling of home quarantine of individuals. Our CDR-based method could be used by other countries, as well as to monitor movement between countries at the European level or internationally, with minimal adaptation effort. The second case introduces a study to gain insight into and better understanding of the potential impact of antivaccination social media activism on the Human Papilloma Virus vaccination campaign in Hungary in 2014. The network analysis of Facebook antivaccination posts and comments showed that during this period, the activists in this network were unable to reach a wider population and were not able to disturb the implementation of the expansion of the well functioning Hungarian public vaccination programme. Unfortunately, this is not the case regarding the COVID-19 vaccination campaign in progress, which suggests that the antivaccination activism is a real and serious security threat to be dealt with. In conclusion, we argue in this paper that the digital transformation of health care, based on the explosive development of information and communication technologies, is of key importance to the establishment of resilient health systems, which are able to cope efficiently with the challenges posed by the rapid environmental changes generated by societal transformation of the 21st century.
