A mechanism of light absorbing by the stratified crystal under the influence of outer magnet field was studied, and an effect of the bistable switching of initial parameters in different directions of its radiation was predicted.
4 individual and 3 group grants were received from the Optical Society of America (OSA), international society of the optical engineers (SPIE), Ministry of Education of France. Scientific and technical cooperation with the Institute for biomedical engineering (Warsaw) and the Department of Optics of the University of Bucharest still continues.

Environmental protection (founded in 1982)
In 2006 10 Doctors of Science and 60 Associate professors took part in the research. A research was carried out and grading of the potential of the development of ecological tourism in the region was elaborated in 2006. There was prepared a description of the main kinds of recreation suitable for ecological tourism in mountainous areas; value assessment of the total resource potential for the needs of green tourism, grading and rating of the esthetics of the landscapes of the region; list and passports of the natural excursion objects of the region.

Basic principles and approaches to the study of karst danger problem were worked out. A complex landscape method of karst investigation was elaborated. The basic factors of karstogenisis were identified. Incongruity of the existing methodological base to the existing problems of the use of nature in the karst regions was exposed.

Due to the research of the novel Romanian literature and its introduction to the Ukrainian scientific circulation, several factors giving an opportunity to show a complete cultural basis of book-printing and functioning of the Church Slavonic language on the territory of the Southern Bukovyna and on the Ukrainian land being a part of Rich Pospolyta by the XVIIth century were revealed.
The prose of Bohdan Lepkyy in the context of West Ukrainian novel writing at the end of XIX – early XX centuries was researched. It is indicated that innovation works of Bohdan Lepkyy have greatly enriched the subject-matter, stylistic and genre palette of the Ukrainian prose of the end of the XIX – early XX centuries.
Systematic genological analysis of all the Ivan Franko’s lyrics was made. It was indicated that the achievements of Franko in the field of creation of genre found its continuation in the formation of genre systems of Ukrainian poets of XX century, such as M. Rylskyy, M. Zerov, D. Pavlychko, B. Rubchak, A. Malyshko.
