The presented paper encompasses four threads of deliberation that show the essence, cognitive value and utility of the concept of creative cities in the shaping of the future of contemporary cities. These threads are: creative development, a model of a creative city, preconditions of a creative city, and the use of a creative city as a vehicle of development.

The meaning and scope of the concept of security in extenso, as well as its special type, i.e. maritime safety and security, has been the subject of many considerations and discussions for decades, and perhaps for centuries. Security is most often understood as one of the basic functions of the State implying counteracting all threats. In axiological terms, as a risk-free state, maritime safety is a value, and in functional terms, as a desirable state, it is expressed in the protective function of law. The law must be structured in such a way as to constantly realize this function. Achieving maritime safety can therefore be seen as the capacity of law and institutions, for example, to protect a ship against loss, protect health and life of people employed on a ship, and protect the environment from pollution.

The paper is an exploration of the optimal design parameters of a space-constrained electromagnetic vibration-based generator. An electromagnetic energy harvester is composed of a coiled polyoxymethylen circular shell, a cylindrical NdFeB magnet, and a pair of helical springs. The magnet is vertically confined between the helical springs that serve as a vibrator. The electrical power connected to the coil is actuated when the energy harvester is vibrated by an external force causing the vibrator to periodically move through the coil. The primary factors of the electrical power generated from the energy harvester include a magnet, a spring, a coil, an excited frequency, an excited amplitude, and a design space. In order to obtain maximal electrical power during the excitation period, it is necessary to set the system’s natural frequency equal to the external forcing frequency. There are ten design factors of the energy harvester including the magnet diameter (Dm), the magnet height (Hm), the system damping ratio (ζsys), the spring diameter (Ds), the diameter of the spring wire (ds), the spring length (ℓs), the pitch of the spring (ps), the spring’s number of revolutions (Ns), the coil diameter (Dc), the diameter of the coil wire (dc), and the coil’s number of revolutions (Nc). Because of the mutual effects of the above factors, searching for the appropriate design parameters within a constrained space is complicated. Concerning their geometric allocation, the above ten design parameters are reduced to four (Dm, Hm, ζsys, and Nc). In order to search for optimal electrical power, the objective function of the electrical power is maximized by adjusting the four design parameters (Dm, Hm, ζsys, and Nc) via the simulated annealing method. Consequently, the optimal design parameters of Dm, Hm, ζsys, and Nc that produce maximum electrical power for an electromagnetic energy harvester are found.

Pope Francis often speaks about the new evangelization. He notices areas that need a special care of the Church. One of them is the problem of poverty. The Pope encou-rages all the faithful to engage in the transformation of this situation . It can be called a “throwaway culture” and a sign of real poverty of the whole society when people remain indifferent to the cause of the poor. It is one of the negative consequences of the culture of prosperity. The Pope also calls it a “globalisation of indifference” and calls on all people of the three states in the Church to care for those who are poor and abandoned and to act against poverty. In a particular way Francis addresses his appeal to the consecrated persons, encouraging them to contemplate the poor Jesus, to the consecration of their lives through a faithful fulfilment of their vow of poverty and to the apostolate among the poor and the marginalized . By means of such an attitude of men and women religious they would contribute to their own sanctification, to bearing witness to love to the poor before the world and at least partly they will help those in need among whom they live and serve.

In the collection of the Kórnik Library there is an unfinished project of a heraldic plate (call number D. IV. 131) which was mentioned in the book by Stefan Kuczyński „Polish land arms: genesis, content, functions”. This article is the first attempt to analyze this forgotten and never completed heraldic project of Tytus Działyński. The heraldic design is a rectangular piece of paper with glued drawings of coats of arms of provinces, sometimes with notes. They are arranged according to the administrative division of the Polish–Lithuanian Commonwealth. A comparative analysis discovered the sources of the engravings of coats of arms which were used in the project. It was also established that the project was created between 1859 and 1861.
