The Krzemionki Hill located in the eastern part of Kraków consists of green meadow terraces which go far back into the history of the city which once acted as a fortress. The hill is an excellent vantage point. By discussing the history and values of the hill, the author suggests that it should be preserved as an extensive lawn, and be used for recreation, socializing and as children’s playground.
The goal of the article is to start a discussion on the possibility of planning tourist and recreational functions in the Polish system of spatial planning. The method the author has adopted is an analysis of the texts of the binding legal acts on spatial planning and development of tourism and recreation. Assessment was carried out of the legal regulations concerned with the planning documents on the national, regional and commune level. Analysis was done of the correlation between these documents and their impact on the structure of spatial planning of tourist areas. A series of executive acts related to the subject topic was listed with regard to their cohesion with the legal system and their implications. On the basis of the studies that were carried out a series of difficulties was discovered in the approach to the problem of tourism development on the various levels of spatial planning. They usually result from the fact that planning documents are too generic and that they are not cohesive with the executive acts.
The goal of the article is to answer the question: what are the chances of formation tourist and recreational areas in the existing system of spatial planning? The strategic spatial planning documents developed on the national and regional levels are aimed at the stimulation of the economic development of Poland including tourism as one of the main branches of the economy. In the existing legal system the documents that are developed are of generic nature and as such are not helpful in finding particular spatial solutions for the management of tourist and recreational areas. There are no applicable legal regulations laying down what the content of such documents should be, in particular there is no resolution on the scope of the spatial management plan in the voivodeships.
Artykuł traktuje o występowaniu infradźwięków i hałasu niskoczęstotliwościowego oraz jego wpływie na środowisko. Przedstawiono definicję infradźwięków oraz omówiono ich specyfikę. Wyjaśniono różnice między infradźwiękami a hałasem słyszalnym. Ukazano naturalne źródła hałasu niskoczęstotliwościowego w środowisku. Wyjaśniono, dlaczego infradźwięki są powszechne w środowisku i dlaczego nie można ich wyeliminować. Pokazano również przykłady badań infradźwięków i hałasu niskoczęstotliwościowego na terenach rekreacyjnych. Zaprezentowano wyniki tych badań. Omówiono znaczenie Międzynarodowego Systemu Monitorującego Infradźwięki na Ziemi. Przedstawiono wpływ infradźwięków na organizm człowieka. Zwrócono uwagę na zależność między emocjonalnym stosunkiem do źródła dźwięku a subiektywną oceną wrażenia słuchowego.
The aim of the study was to estimate the occurrence (the quantative and rate percent) of Ixodes ricinus in the popular recreation areas in Szczecin (Arkonka, Osów, Głębokie, Landscape Park of Szczecin, Dąbie Forest Park, Zdroje Forest Park) and in province of Szczecin (Forest of Goleniów, Ińsko, Pobierowo, Chojna). Investigations were performed in 1998 year, twice on each places; in May/June and repeted in September/October. The temperature and humidity of air were measured. Obtained specimens were regard of sex and growing stage during each collection. A total of 2.055 specimens collected 49% were nymphs, 13.9% female, 11.3% male and 25.8% larvaes. The nymphs the most frequently were in spring when humidity of air was 55% and temperature 24°C. The larvaes, in autumn were most frequently (31.4%) then in spring (20.5%) when the temperature of the air was 18-22°C, and the humidity from 60 to 85% during the collections.
Among Polish ticks species the most common Ixodes ricinus has the biggest medical importance. Within the last few years, the incidence of disease transmitted by ticks has rapidly increased. We have made a thorough analysis of the quantative and rate per cent of occurrence of various stages Ixodes ricinus in the forest areas of some places in Szczecin province and in the parks of Szczecin, that are known as highly recreative and frequently visted by meny people. A total of 426 (68% numphs) specimens collected there show that ticks frequently occupy habitats closely associated with man.
The occurrence of Ixodes ricinus in the selected recreative areas in the province of Szczecin. Part III. Within the last years, the incidences of diseascs transmitted by Ixodes ricinus tick have rapidly increased. We estimated the occurrence of Ixodes ricinus in the popuJlr recreation urban areas in Szczecin and in the Province of Szczecin. The study was carried out in 1999, with two samples at each site, and were compared with data of 1998. The temperature and humidity of air were measured. The most ticks were found in the range of 70-80% relative humidity of air. Among 3.198 specimens collected 59.5% were nymphs, 19.0% larvae, 11.1 % females and 10.4% males. The nymphs were the most frequent in spring and in autumn, while the larvae were most frequent in autumn (26.2%) then in spring (11.9%).
