The issue of urban land management in the world in general and in Africa in particular has been exacerbated by the liberalization of land practices and the commodification of land, which has led to an increase in corrupt practices within land institutions in all cities. A mixed methodology was employed, combining a comparative case study of secondary towns with a quantitative survey of 559 landowners in the towns of Bohicon and Sokodé. In-depth interviews were conducted with 31 informants, who were surveyed on the land acquisition process, the individual determinants influencing corrupt practices, and the institutions most involved in these practices. The findings revealed that the acquisition of a formal title conferring property rights in both cities necessitates the completion of several steps. Corrupt practices are present at almost every stage of the transaction. The application of logistic regression models to the independent variables indicates that age and profession are highly significant in the sociodemographic characteristics of those most susceptible to engaging in these practices. Formal land administration institutions are the most involved in these types of everyday corruption. These practices are ultimately linked to people’s life paths and cannot therefore be combated without psychosociological education and the promotion of ethical behavior among all stakeholders, particularly among those who demand services.

This study investigated changes in lifestyles and psychological anxiety among Koreans during the Coronavirus Disease 2019 (COVID-19) pandemic using the 2020 data from the nationwide Korean Community Health Survey. The study outcomes were psychological anxiety about the infection and death, due to COVID-19. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the relationship between psychological anxiety and lifestyle changes. During the COVID-19 pandemic, people who practiced healthy behaviors and followed social distancing and quarantine regulations experienced increased psychological anxiety for infection and death. Daily life changes during the COVID-19 pandemic were not associated with psychological anxiety. The result of this study can provide baseline measures for further study on psychological anxiety during re-infection of COVID-19 and future pandemics in Korea.

In this paper, a study developed at the University of Seniors in Aragón is presented. The Sono-libro, used as an innovative resource, is assessed in the proposal with an educational and pedagogical purpose. The aim is to understand the motivational and learning perception variation after the incorporation of the Sono-libro in the sample. In this quantitative longitudinal design study, the listening habits of the participants are comparatively analyzed at two moments: The first data collection took place before the implementation of the proposal, and the second collection occurred after the proposal. The sample consists of 116 subjects, with 64.16% being women and an average age of 66 years of age. Data was obtained through a validated ad hoc questionnaire judged by experts. The results of the data collections showed an increase in both motivation and perception of the learning obtained, indicating the benefits of incorporating digital resources into contexts of adult students.
