SummaryRounded atelectasis of the lung is well described in medical literature, but still difficult to diagnose. Since lesions give no clinical symptoms in patients, radiologists are often the first to recognize the round lesion in an X-ray picture or a CT scan. Rounded atelectasis is an atypical form of lung collapse that usually occurs adjacent to scarred pleura and can be mistaken for lung cancer. Patients with rounded atelectasis have a history of asbestos exposure or pleural effusion due to various causes. When characteristic imaging findings are present, the diagnosis is rarely dubious and no further investigation is necessary. However, differential diagnosis of rounded atelectasis poses a challenge to pulmonary specialists and radiologists.

The main research problem discussed in this paper involves evaluation of the motives of agricultural producers for pursuing and developing organic production. The aim of this study is to identify and evaluate the role of social values in stimulating decisions of involvement in organic production. Analytical observations were conducted on the basis of responses to surveys on a nation-representative sample in Poland (350 conventional farms and 70 organic farms in 2011; 260 conventional farms and 65 organic farms in 2019). Analyses were conducted in relation to the potential and perspectives for development of organic farming. They were focused on identifying the original motives for such decisions (incentives and disincentives). This allowed for effective evaluation of both the trend and the pace of the studied processes. The development potential of organic farming in Poland was estimated at 5–15% of the total number of farms. The most important factors encouraging farmers to take up production are associated with social values (care for the natural environment and family health). A significant chance for the development of organic production is the expected demand growth, which is also related to social values: the increasing environmental awareness and environmental change of consumption patterns.

Development of both the marketing and cultural sectors have multi-directional natures, showing relationships with sustainable development that should be considered at various levels of cultural sector management in cultural institutions, at the level of the cultural policy of the state or region, and on the micro-scale. Not only do the natural environment, economy, and technology constitute areas of sustainable development, but also society and culture. The assumptions about sustainable development by cultural institutions are related to implementing marketing concepts in this sphere, in that they are the expression of market orientation (on consumer of culture). The goal of this study was to show that marketing by cultural institutions, as a reflection of their market orientation, translates into these institutions’ implementation of the assumptions of sustainable development. This paper is based on literature studies and the results of empirical and quantitative research that was conducted on a sample of 451 people managing cultural institutions in Poland. The research included general managers, managers, artistic directors, managers of marketing, promotion and sales departments, as well as owners of cultural institutions. Analysis of research results shows that consumers of culture are ranked first as recipients of targeted actions conducted by cultural institutions. An increase in the diversity of cultural offers, including the concept of sustainable development, emerged as a factor stimulating the development of the culture market, being closely related to growth of the quality of cultural offer.
