Opis:
Radon and its short-lived disintegration products are the most significant factors of exposure to ionizing radiation from natural sources. Białystok has the population of about 300,000 inhabitants in 100,460 flats in 16,282 houses. They are mostly one-family houses (about 80.7per cent) and two-family houses (8.2 per cent). It can be estimated that about 2/3 of the Białystok inhabitants live in the so-called “blocks of flats”. The study aimed at evaluation of the exposure to radon present in the flats. The integral method of trace detectors was used to measure radon concentration indoors. All values of the radon concentration were the mean annual values as they were obtained on annual exposure or were calculated and corrected to annual exposure based on shorter periods of time. Radon concentration distribution in flats of 3 housing estates in Białystok was analyzed. The effective dose of inhaled radon per a statistical inhabitant of Białystok (about 1.1 mSv) per year was calculated on the basis of mean values of radon concentration. Inhabitants of one-family houses obtained slightly higher annual doses – 1.4 mSv while the inhabitants of block of flats got lower annual doses – 0.8 mSv.

Opis:
Water is one of the indoor sources of 222Rn. As radon is soluble in water, it is carried indoor by water supply and there it is released. The presence of radon in groundwaters is caused by direct migration of 222Rn from rocks and soil to waters as well as by radium content in water. Radon inflow indoor is possible in the areas where drinking water shows high radon concentration. Radon concentration changes significantly from low in natural surface water to relatively high from water in drilled wells. It is estimated that out of 10,000 Bq·m–3 of radon contained in water supply we can obtain radon concentration increase by 1 Bq·m–3 indoor. The aim of the study was to measure radon in water supply in the Białystok region and also estimation of doses and investigation how the treatment influenced radon concentration in water. Water was collected from rural and municipal waterworks as well as from home wells. Measurements of radon concentration in particular stages of drawing and treatment of water in Białystok waterworks were also conducted. A liquid scintillation method was used in the study. The arithmetic mean of radon concentrations in the samples was equal to 5800 Bq·m–3, median – 4800 Bq·m–3, and geometric mean – 4600 Bq·m–3. The lowest values of radon concentration were observed in surface waters (from surface intake). Radon concentrations in waters from drilled wells, shallow home wells and surface intake were compared and statistically significant differences were obtained at p < 0.05. The results of radon concentrations in drinking water in the Białystok area revealed radon-poor waters (88%) and low-radon waters (12%).

Opis:
Scharakteryzowano warunki geologiczno-górnicze prowadzonej eksploatacji, występujące w rejonie pola G-7/5. Opisano przebieg robót górniczych od momentu rozpoczęcia eksploatacji w 2002 r. Przeanalizowano wyniki prowadzonych badań i obserwacji zachowania się górotworu oraz dokonano oceny stanu zagrożenia sejsmicznego w polu. Złoże rud miedzi w polu G-7/5, zlokalizowane jest na głębokości około 870 m, w skrzydle wiszącym uskoku "Biedrzychowa". W polu wydzielono trzy bloki eksploatacyjne. Bardzo trudne warunki geologiczno-górnicze w polu, zwłaszcza w bloku "A", powodowały wielokrotne zmiany kierunku prowadzenia robót, w tym na zroby i strefy upodatnione. Obecnie prowadzone są roboty likwidacyjne w bloku "A" i roboty rozcinkowe w bloku "B", które uruchomiono w sierpniu 2010 roku. Ze względu na poziom aktywności można wyróżnić trzy okresy podczas prowadzonej eksploatacji od października 2009 do września 2010 roku, które odpowiadają specyfice prowadzonych robót wybierkowych oraz stosowanej profilaktyce zagrożenia sejsmicznego. Lokalizacja ognisk silnych wstrząsów wskazuje, że większość z nich występowała w liniach uskoków, przebiegających przez strefę roboczą pola G-7/5 oraz na krawędziach prowadzonej rozcinki złoża. Dotychczasowej eksploatacji towarzyszył stosunkowo wysoki poziom zagrożenia tąpaniami i zawałami, głównie ze względu na zaangażowanie tektoniczne.
In the paper geological and mining technology conditions in "G-7/5" panel of Rudna Cooper Mine was described. The mining process started in 2002 is presented as well. The results of rock mass observations and measurements were characterized and seismic hazard in "G-7/5" panel was evaluated. Ore body in "G-7/5" panel is located at a depth of 870 m in the downthrown side of "Biedrzychowa" fault. "G-7/5" panel is composed of three smaller excavation blocks. Hard geological and mining conditions in this panel, especially in block "A", often result in mining direction changes e.g. toward old workings and yielding zones. At present in block "A" liquidation works are carried out. In block "B" face-entry drivage was started in August 2010. Depending on activity level, during mining in that area between October 2009 and September 2010, three different periods can be distinguished. They correspond with the specific character of mining works and prevention methods against seismic activity hazard. Location of mining tremors indicate that many of them occurred in faults lines running through the working area in "G-7/5" panel and on the block development edges. Due to tectonic dislocations in this area, mining in "G-7/5" panel was connected with relatively high level of bumps and roof falls hazard.

Opis:
The theoretical analysis of the consequences of the phyllotactic pattern being propagated according to the first available space rule has revealed that all monojugate patterns, with the exception of the main Fibonacci pattern, should become developmentally unstable in their low expressions. This fact explains why the main Fibonacci pattern plays the dominant role among other patterns of spiral phyllotaxis. The probability that the pattern becomes unstable varies for different patterns, which likely makes them more or less frequent, and thus easier or more difficult to encounter in nature. The unstable pattern inevitably transforms into another, as the computer simulations show. Theoretically predicted instability of low order phyllotaxis may be treated as one of the causes of natural ontogenetic transitions, occurring in plants. This, however, still does not explain why in nature some patterns with high order of phyllotaxis also change, quite readily one into the other, in shoot apical meristem’s ontogeny.

The aim of the study was to evaluate differences in the results of the curative treatment received by women with breast cancer in urban and rural area in Podlaskie Voivodship in 2001-2002 before the introduction of the National Cancer Control Programme. The analysis was based on 449 women with breast cancer, who received curative treatment in years 2001-2002. Relative 5-year survival rates as function of age and stage among urban and rural women population were calculated. The results showed that survival rates in Podlaskie Voivodship among curatively treated women with breast cancer were 81.9% but they differed between urban and rural areas. Patients living in rural areas had much lower survivals than those living in urban areas at local and regional stage of disease. In all age groups considered in the study survivals in rural areas were lower than in urban ones in which survivals were higher in 55-64 age group. These results indicated the necessity intervention in order to increase the access to the health care system and effectiveness of early detection and also improved treatment standards for more disadvantaged rural areas. These results should be also considered in monitoring of the National Cancer Control Programme introduction in Poland in 2006.

Introduction. Health education used for increasing the effectiveness of intervention actions should cover a number of factors which exert an effect on learning. Objectve. Recognition of the extent to which gender may determine the effects of an anti-tobacco health education programme. Material and methods. The intervention study was undertaken in May 2007, and covered 859 first-year schoolchildren in Białystok. The sample was selected by means of two-stage stratified sampling with consideration of two groups: an intervention group and a control group. Results. In the group of girls, the 2-year educational programme resulted in an increase in knowledge concerning the negative effects of cigarette smoking by 21%, and being familiar with anti-tobacco actions and campaigns carried out in Poland by 24.5%. Among boys, an increase was observed only with respect to the knowledge of anti-tobacco actions and campaigns – by 10.7%. Considering the attitudes of girls after the completion of the programme, changes were noted with respect to three from among the six elements analyzed. However, among boys, after completion of the project, no changes were noted in any of the analyzed elements of attitude. In girls who participated in the anti-nicotine programme, the percentage of smokers did not increase, while an increase in this percentage was observed among girls of the control group and boys in both groups. Conclusions. Different effects of the 2-year anti-tobacco programme obtained in the area of knowledge, attitude and behaviour should constitute a premise for the modification of educational programmes from the aspect of the variety of methods, techniques and instruments which would be adequate for adolescents’ predispositions resulting also from their gender.

Introduction. School health education programmes are among the instruments for the prevention of tobacco smoking among children and adolescents. Knowledge obtained in evaluation studies of these programmes indicates the degree of their effectiveness and serves to improve their quality. Objective. Recognition and evaluation of the effect of two-year anti-tobacco programme of health education on the changes in the level of knowledge, attitudes and behaviours of adolescents. Materials and method. An intervention study was originated in May 2007, and covered 859 first-year schoolchildren from eight public junior high schools in Białystok in Poland, from among 3,318 schoolchildren attending 33 schools. The sample was selected by means of two-stage stratified sampling with consideration of two groups: an intervention group covered with educational actions (417 schoolchildren), and a control group (442 schoolchildren), where anti-tobacco education was not carried out. Before the educational programme and after its completion an evaluation of knowledge, attitudes and behaviours of junior high school adolescents was performed with respect to nicotinism, based on a survey. The educational part consisted in conducting within 2 years, 4 educational classes and 2 competitions concerning tobacco-related problems. Results. After two years, in the group of adolescents covered by the educational programme a significant increase was observed – by 11.6% – in the percentage of schoolchildren who were familiar with the negative effects of tobacco smoking, and an increase by 4.4% of those who were convinced that smoking is harmful. With respect to adolescents’ attitudes, the effect of the programme was noted in only one of six components analyzed. After completion of the two-year educational programme, both in the group covered by this programme and the control group, the percentage of smokers significantly increased (by 12.8% and 12.7%, respectively). Conclusions. It is necessary to evaluate the health education programme from the aspect of both the actual hard effects of the anti-nicotine programme (changes in behaviour), and indirect effects – soft (knowledge, skills) which are a basis for the potential verification of the programme in order to increase its effectiveness.

Introduction. The results of breast cancer treatment depend mainly on better detection in mammography screening and, consequently, a higher proportion of women with early stage of the disease. They depend also on a better access to health care services and the effectiveness of oncological treatment. One of the methods of breast cancer control is a breastconserving surgery. With a proper patients’ classification for the treatment, the results of the breast-conserving surgery do not differ in relation to mastectomy. That’s why, the availability of breast-conserving surgical methods is particularly important, especially in a population in which a population screening is conducted. Objective. The analysis of the selected aspects of the breast cancer treatment’s standard in Podlaskie Voivodeship. Patients and methods. In years 2001–2002, 709 cases of women with breast cancer were reported to the Voivodeship Cancer Registry in Bialystok. 659 women were diagnosed with a primary invasive breast cancer. Based on a cohort of 499 women treated with radical methods the following indicators, recommended by WHO for the evaluation of the breastconserving surgery’s availability, were calculated: a percentage of patients with whom breast-conserving surgery was used, a proportion of breast cancer cases receiving post-operative breast radiotherapy after breast-conserving surgery and a proportion of breast-conserving surgery in pT1 cases. Results. The breast-conserving surgery has been used much less frequently in Podlaskie Voivodeship than in Western Europe, but more frequently than in Poland in general. Conclusion. It should be aimed to provide a surgical treatment with the use of breast-conserving surgical methods to the highest possible percentage of patients. The increase of the percentage of patients treated with breast-conserving surgery methods can be a result of an effective screening realisation.

Introduction: Treatment delay is a major problem of contemporary oncology. Knowing the time interval between diagnosis and initiation of treatment, together with monitoring this adverse prognostic factor, is an important element of the treatment planning process in the population and can contribute to the improvement of patients’ curability. Objective: To assess the waiting time for first treatment of women diagnosed with breast cancer in 2001-2002 in Podlaskie Voivodeship. Materials and methods: During 2001-2002, there were 709 cases of women with breast cancer who reported to the Voivodeship Cancer Registry in Bialystok. 659 women were diagnosed with a primary invasive breast tumour. A cohort of 499 women who were treated with a curative intent was selected from this group. The waiting time in the created cohort was calculated as the number of days between the date of the breast cancer diagnosis and date of the first treatment. Results: The average time between the date of diagnosis and date of the first treatment was 38 days. The median was 14 days. 28.6% of patients from the selected cohort waited longer than 28 days. The treatment of rural women was initiated faster than the treatment of urban patients.
