The Operating Room Scheduling (ORS) problem deals with the optimization of daily operating room surgery schedules. It is a challenging problem subject to many constraints, like to determine the starting time of different surgeries and allocating the required resources, including the availability of beds in different units. In the past years, Answer Set Programming (ASP) has been successfully employed for addressing and solving the ORS problem. Despite its importance, due to the inherent difficulty of retrieving real data, all the analyses on ORS ASP encodings have been performed on synthetic data so far. In this paper, first we present a new, improved ASP encoding for the ORS problem. Then, we deal with the real case of ASL1 Liguria, an Italian health authority operating through three hospitals, and present adaptations of the ASP encodings to deal with the real-world data. Further, we analyse the resulting encodings on hospital scheduling data by ASL1 Liguria. Results on some scenarios show that the ASP solutions produce satisfying schedules also when applied to such challenging, real data. 1 [ABSTRACT FROM AUTHOR]

The 50s of the XVI century were introduced, in Bosa, by the appointment of the new bishop Joan Saguini: an intellectual who triggered a virtuous dynamic in the events of the city, culminating in the enfeoffment – by the King of Aragon John II – to the Vilamarì family, followed by about fifty years of economic prosperity. This is the context in which the creation of the royal chaplaincy of the castle of Serravalle, an office maintained over time, even in the Savoy era. This happy moment of the economy of the capital of the Planargia is also reflected in the few surviving material testimonies today, including the small statue that started the devotion of the citizens of Bosa for the Madonna of Regnos Altos.

During the 16th century, the churches of St. Lucia and of the Purissima, in the city of Cagliari - linked to two new communities of franciscan female monasteries - were object to architectonic reformulation. Two important families, originally from the Aragon, had role in the initiatives: the Ram and the Ruecas. Hypothetically, through the aragonese people, it is diffused in Sardinia the type of tardogotiche vaults with five keystones, adopted for the first time in St. Lucia; promoting, at the same time - through the devotion from the nuns of the Purissima and the marriages between families, which were part of the oligarchy of the city - the cult of the Immaculate Conception.

This essay intends to reconstruct the forms of interaction within Sardinian and Iberian painting workshops in the period between the last phase of Gothic and the early beginnings of the Renaissance language. In particular, it deals with the mobility of artists, the circulation of works and their stylistic contaminations. The role of arts is regarded as a means of communication and of social emancipation as well as from the point of view of professional regulations. [ABSTRACT FROM AUTHOR]
