Резюме: Настоящата разработка изследва мотивацията за обучение сред курсантите от ВВМУ “Н.Й. Вапцаров” в професионално направление “Военен лекар”, както и мотивите, стимулите и демотивиращите фактори, които оказват силно въздействие върху нея. Изследванетоочертава и приложни перспективи за оптимизиране на механизмите за мотивация, валидни за обучението във военно-медицинската професия, с цел повишаване качеството на подготовката на тези кадри.

: In recent decades, there has been a strong growth of the cruise industry, which has managed to develop innovative concepts in terms of safety and security service and to offer attractive vacation to the exotic destinations around the world. Thus, the cruising has gradually become a major part of the tourism sector and has become one of the main economic factors for development of shipping industry. Based on analysis of the global demand on cruising this article defines the factors influencing the development of cruise fleet and leading cruise lines and provide a vision for future efforts in field having in mind also the dynamic changes in current situation.

: The article reveals the possibility of solving optimization tasks for security risk management in a specific social system. The application of modern technological solutions to support the assessments contributes to the assessment objectification and the scenarios based methods application. The modeling of security processes and their reproduction, including repeatedly in a simulation environment can be used to solve optimization tasks to ensure security. The optimization task for security risk management has been formulated as methodology for solving the problems in the laboratories of work package "Risk Management" of the Center for Competence QUASAR

The paper examines the dynamics of the common forms of iron and manganese in the surface water of the Bulgarian Black Sea coast. The samples were collected in the period 2012-2014. The seasonal dynamics of both metals was tracked. The results show low iron concentrations in spring and autumn. High concentrations of both metals were observed in Varna and Burgas Bays during the whole study period.

In a number of publications and media notices, popular foreign and national seismologists admit that their field still does not possess exact methods and technology for short-term earthquake forecast. A number of facts, events, conditions and considerations are presented with the aim of motivating the need for immediate experimentation of a Bulgarian patent of a device for capping gas wells with attachments for transmitting to the receiver on land certain characteristics of the underwater gas well indicating impending earthquake.

In the summer of 2019, a study was conducted on the development of phytoplankton in Black Sea waters along coastal fortification facilities /groins/. The aim was to study the characteristics of phytoplankton during the summer in coastal areas subject to eutrophication pressure. Relatively low quantitative quantities of phytoplankton were found, no blooms was observed. Higher amounts of phytoplankton were recorded on the right side of the coastal fortification facilities.

Total organic carbon in the surface water in front of the Bulgarian Black Sea coast was investigated episodically over the period 2014-2016. During 13 expeditions conducted with R/V Akademik, samples were collected at stations located in the one-mile zone along the coastline. The results obtained varied from values of the limit of quantification (LOQ) <1 to 10 mg/l. In spring TOC concentrations were lower than in summer and autumn.
