Given that deterioration of adolescents’ health status during pandemic is well documented, health related quality of life (HRQoL) assessment is very important, as it contributes in adolescents’ development and maturation into healthy adults. The main purpose of the study was to assess adolescents’ HRQoL during the two strict lockdowns due to COVID-19. Secondary aims were to examine differences in HRQoL with regard to gender, and physical activity/sport participation before and during lockdowns. It was a cross-sectional study and conducted during first and second strict lockdowns. Three hundred and sixty-three adolescents (Ν=363) from secondary schools, in the Greek territory (108 boys and 255 girls) filled in the TNO-AZL Questionnaire for Children’s Health-Related Quality of Life Children’s Form, online, once. Also, demographic and anthropometric data were collected. For all TACQOL-CF subscales results showed that scores were lower, than the maximum subscales scores. Also, adolescents’ responses to open questions supported further the low subscales scores. In addition, adolescents who participated in sport before lockdowns reported better scores in motor functioning/performance during lockdowns than their non-physically active peers (p<0.05). Moreover, girls reported significantly lower scores compared to boys in general physical functioning/complaints subscale (p<0.05). The findings of this study highlighted that during the two strict quarantines adolescents’ HRQoL was deteriorated. Sport participation before the pandemic influenced positive HRQoL during quarantines and also quarantines affected differently adolescents by gender. Thus, the results should give information in adopting preventive strategies by policy makers to alleviate long-term negative consequences, in order adolescents to gain pre-pandemic HRQoL levels, in the transitional post-COVID-19 era.

Following one of our research lines, we present here the first English translation of four speeches of Alfred Rosenberg related with freedom of research, science and worldview, Gutenberg’s invention, Nicolaus Copernicus and Immanuel Kant. Some of his philosophical thoughts are still valid today and deserve more analysis.

It is commonplace that the knowledge and use of foreign languages contribute positively to various and diverse fields in all countries of the world as well as to many social, cultural, labour, commercial, economic, political discussions and interactions of any civil society. Their role has been decisive in the past, still is today and it is more than evident that foreign languages will continue to play a decisive role in the future, especially on the personal, collective, state and cross-border levels, due to the ever-increasing mobility of people, whether voluntarily or involuntarily, from one continent to another, from one country on the same continent to another, from one poor, war-torn, oppressive and fascist country to a peaceful, democratic one, from one democratic country to another democratic one, etc. In particular, it plays a key role in: a. the acceptance of others with different origins, culture, religion, language, etc.; b. the mutual understanding, communication and the establishment of social relations between citizens of different cultures; c. the intellectual cultivation, cultural exchange, personal, professional rehabilitation and development of people; d. the conception and understanding of citizens that education and culture are the main pillars of the economic development of a country and of each individual; e. the cultivation and promotion of interdisciplinarity and the general progress of science and research; f. the friendship between States; g. the diplomatic (inter)negotiations, commercial transactions, various agreements between States. The present paper has been written for all these reasons and a few more discussed further on. It studies in a critical-interpretative way various aspects of the teaching and learning of German as a foreign language in Greece, a language spoken by several million people all over the world.
