CONTRIBUTION TO THE RECOGNISION OF LICHENS IN BELLSUND (SW SPITSBERGEN)
MAŁGORZATA JÓŹWIAK
Key words: thallus, fruiting body, spores, habitat, „green zone”.
Lichens are a group of funguses that narrow down coexistence with symbiotic component – eukaryotic photobiont: Chlorophyceae representative (90%) or prokaryotic Cyanophyta (10%). Coming into relationship and forming a complex physiological system is named lichenization, and taxa-lichens formed in such a way are lichenized funguses. Physiological feature of lichens is that they are biotopic pioneers. Their role as pioneering forms is of remarkable importance in polar regions where they enter areas exposed by melting glaciers. Lichen species list from Spitsbergen region was elaborated by Lynge (1938), Elvebakk, Hertel (1996) and there is no information about any future attempts to verify or update it.
Field research was performed during stay in Spitsbergen in August 2003 and 2007. Herbarium material was collected from the area in the west side of Calypsostranda. Lichens were determined with classical taxonomic methods. Comparing the above lichen species list to the material collected in August 2003 and 2007 and determined allows to supplement the list with 6 species, i.e. Cetraria delisei (de Bary ex Schaer) Kärnefelt & Thell, Cetraria hepatizon (Ach.) Vain, Cetraria islandica (L.) Ach, Flavocetraria nivalis (L.) Kärnefelt & Thell, Cetraria aculeata (Schreb.) Ach, Flavocetraria cucullata (Bellardi) Kärnefelt & Thell.

NANOCOMPOSITE MATERIALS – THERMAL PROPERTIES
AND APPLICATION FOR HYDROGEN DETECTORS
Joanna Rymarczyk
Key words: detector, nanostructural films, palladium nanograins
Interest in construction of new ecological (in meaning of ecological materials) detectors of gases and liquids arises in last years. Now researchers are looking for a solution for construction of detector which enables for faster detection and posses’ high sensitivity. The important feature of such detector should be its multi function. The interest in nanomaterials application in electronic devices grows in results of miniaturization and technical development.
Nanostructural films containing palladium nanograins synthesized in Tele & Radio Research Institute can be applied as active layer in hydrogen detector. Due to a complicated method of study of such nanostructural materials a mathematical modeling is often used for predictions of some properties of these materials. In this paper the structural model of the construction of film composed of palladium nanograins embedded in carbonaceous matrix was prepared on a base of previously obtained results of structural studies. Grate to these modeling the thermal properties of such film could be predicted. The modeling was done with Finite Element Method and ANSYS program (Ansys, Inc). The effects connected to convection at different temperature and their influences on temperature gradient in film volume were studied. The results of this modeling study showed in the places of Pd nanograins location the biggest temperature gradient. This effect is important because of its consequences connected to the film damage due to stress creation. This effect should be taken into consideration while the film is used in high temperature gas detectors.

THE REGIONAL EDUCATION IN SCHOOL PRACTICE AS THE INSPIRATION FOR HIGH SCHOOL STUDENTS
ILONA ŻEBER-DZIKOWSKA
Key words: questionnaires research, research, interdisciplinary education, regional education,
school, the fourth stage of education
The aim of the regional education in the didactic and educational process is to create the feeling of students’ own regional identities. The regional identity is understood here as the attitude towards the dedication to their own environment functioning as well as the authentic openness towards different societies and the cultures.
As the result of educational reform at schools, the necessity of introducing different educational paths, e.g. the regional one appears. Their realization should be the addition of knowledge in this field. The regional education in school practice should be the inspiration for the teachers and students so as to improve their interests, to effort and to introduce the changes. Therefore, they have the fundamental educational significance.
In 2005 in order to get the students’ opinion on the subject of the so-called ‘regional paths’ the research in the area of Ostrowiec Świętokrzyski administrative district was conducted. Six high school participated in the research. 514 students filled in questionnaires specially prepared for the research.
Therefore, no matter how long the regional education is present at schools (in many schools for a long time), do the teachers realize the lack of special instructive and methodological help as well as the appropriate material – publications dealing with the region, illustrative material, etc.

MATERIALS TO THE KNOWLEDGE OF TRUE BUGS (HETEROPTERA) “MIEDZIANKA HILL” NATURE RESERVE (CHĘCIŃSKO-KIELECKI LANDSCAPE PARK)
Emilia Walczyk
Key words: Heteroptera, species composition, abundance, xerothermal grasslands,
Świętokrzyskie Mountain region
“Miedzianka Hill” is a calcareous rise situated in the west part of the Świętokrzyskie Mountain region. This area is overgrown with a xerothermal grasslands and shrubs of classes Festuco – Brometea, Trifolio – Geranitea sanguineiand Rhamno – Prunetea. Bugs fauna was studied in two consecutive years: 2007 and 2008. Insects were
collected with an entomological net in open habitats from four stands. Altogether 90 species and 3233 individuals were found (tab. 1). In regard of abundance Ortholomus punctipennis, Coptosoma scutellatumand Adelphocoris lineolatuswere the most numerous species. A lot of species noted here were related to warm, calcareous habitats. Among them the most interesting due to rarity are: Halticus luteicollis, Polymerous asperulae, Cydnus aterrimus, Lygaeus equestrisand Rubiconia intermedia.

THE NATURAL SCIENCE EDUCATION DURING THE SO-CALLED
“GREEN SCHOOLS” AS THE POSSIBILITY OF IMPROVING
THE TEACHING – LEARNING EFFECTIVENESS
Elżbieta Buchcic
Key words: green schools, environmental education, field (outside school) activities,
scientific education, methods and form of organization, didactic activities.
The so called “green schools” are the activities that take place outside schools and last for a few days. They are the activities, whose role becomes more significant in the modern process of education. It is an extremely valuable form of teaching and learning process because it enables to get to know the cultural scenery especially including natural, historical and aesthetical values. During such a process, the cognitive values are accompanied by a process of shaping the desirable pro-ecological attitudes. They also enable to obtain the new information, to learn about different places, to gain the skill of independent learning, to carry out the observations as well as to analyze them and to come to the conclusions on their basis.
