Opis:
Na przykładzie wyników badań polegających na porównywaniu zapachów 14 substancji przez dużą grupę osób, przedstawiono metodę konstruowania skali uciążliwości zapachów, sposoby interpretacji zastosowanych metod statystycznej analizy preferencji oraz sposób wstępnego wyboru 6 wzorców zapachowych.
The easy to handle and usefull portable standard for hedonic judgement of odors should consist of 5-6 microencapsulated various odorants to comparisons with evaluated odor in practice. In present study the 14 odorants were investigated on purpose to select the 6 ones. The group of judges was engaged and each odorant several times was classified as more or less unpleasent then one from 13 others. The set of indivudal preference relations was analized by two ways. First, the best acceptable sequence of all 14 considering odorants was computed and diveded into 6 clusters. The single optional representative of each cluster was included in designed standard. The alternative approach bases on the best acceptable sequences of only 6 odorants from 14 considering ones. Thus, circa 50 primary solutions were obtained. Then the elimination from practical and medical points of view were executed and finally two follow standards are recommended: 1) anethole, 2) n-butyl alcohol, 3) acetone, 4) tetraline or indole, 5)isobutyric acid, 6) 2-mercaptoethanol.

Opis:
W pracy opisano wyniki statystycznych obliczeń porównujących oznaczanie wapnia i fosforu dwoma sposobami: metodą laboratoryjną (x) i metodą obliczeń teoretycznych (y). Oba składniki badano w całodziennych racjach pokarmowych dzieci do 1 roku życia. Wykazano, że pomiędzy wynikami uzyskanymi tymi metodami istnieje dość dobry stopień korelacji, choć wartości średnie obu metod różnią się istotnie.
The results of two methods for the estimation of calcium and phosphorus in daily rations of children aged up to 1 year were compared by ample statistical tests. Ca and P contents were determined by the analytical method; moreover, the theoretical Ca and P contents were calculated from the bills of fare menus and food coposition tables. The analytical procedure was accepted as reference method. Ca and P contents determined by the analytical method accounted, on the average, for ca. 90% of those obtained by the calculation method. The coefficients of correlation between the results obtained by both methods (x and y) amounted to: rCa=0.456 and rp=0,786. There were significant differences between Ca and P contents obtained by both methods at significance level α=0.05.

Opis:
This work contains a statistical analysis of crime in Warsaw in 1992 based on the data on crime recorded by the Warsaw Police Headquarters. Changes in the dynamics, structure, and spatial distribution of crime in the years 1988 to 1992 are shown in accordance with the city’s basic administrative division into 17 districts.Territorial differentiation of crime in areas subordinated to the separate police stations (47) is shown in figures and maps of rates and changes in crime in 1992 as compared to 1991. Separated because of their specific nature are typical big city areas, neighborhoods of railway stations and the airport, as well as suburbs.             Changes in crime recorded in Warsaw in 1989‒1992 were relatively much greater than those found on the national scale. An exception here was the year 1990 when a similar growth in the proportion of recorded offences took place both in Warsaw and Poland – by 64% and 61% respectively as compared 1989. After a rapid growth of recorded crime staring in 1989, a downward trend began in 1991 at a pace that was higher in Warsaw than all over Poland.             In 1992, the crime rate (mean numbers of offences recorded yearly per  100 thousand of the population of a given area) in Warsaw was 2.3 times higher than the national average which was a drop as compared to 1990 and 1991 when the indices were 2.7 and 2.6 respectively.             Changes in the extent of crime in the separate districts of Warsaw in 1989‒1992 have been depicted by chain indices of dynamics. The values of those indices manifest considerable differences in the changes in crime between the separate districts, and occurrence of opposing trends in succeeding years. The districts that had the greatest growth in crime in 1990 (Mokotów, Ochota, Praga Południe, Żoliborz) showed the greatest drop next year (1991). A similar trend could be found in 1992 in the districts of Praga Północ and Śródmieście (an increase, relatively high as compared to the other districts, followed by the greatest decrease). These findings may evidence both “displacement” of real crime, and the impact of other factors related to the activities of the police and public prosecutor’s office (in the spheres of both crime prevention and control, and the methods of recording offences).             As shown by analysis of the rates and structure of crime in the separate disricts of Warsaw, the different areas of the city are much differentiated in this repect. In 1991 and 1992, differentiation of the rates crime was three times higher as compared to 1990.             The highest crime rates could be found in Śródmieście – 10265.1, and Praga Północ – 6145.5; this resulted, among other things, from concentration of economic life and a high mobility of the population in those districts which stay busy for twenty-four hours a day. The lowest mean crime rates were found in Mokotów (3664). The next stage of statistical analysis of crime recorded by the police in Warsaw consists in the presentation of the territorial differentiation of crime in the areas of operation of the separate police stations. Differentiation of the crime  rates was very high, ranging from 1,700 offences per 100 thousand of the population recorded at the 3rd station to 27,559 recorded at the 17th station (in Śródmieście district). At the  same time, as was the case with crime analysed by city districts, a reverse trend of the changes in rates and intensity of crime could be found. In some areas which, admittedly, had the relatively lowest crime rates in 1992, there was a relatively high growth in crime as compared to 1991. In Śródmieście  district, despite the drop in crime in 1992 as compared to 1991 (which was the highest at the 17th station ‒ by 31% and the lowest at the 26th station – by 8%) the crime rates per 100 thousand of the population proved among the highest. This may confirm the thesis as to “displacement” of crime. On the  other hand, it may also result from different relations between the extent of real crime and that of recorded offences. What speaks for these latter conclusions are the results of regression and correlation analysis which manifest a significant correlation between the rates of recorded crime in general and offences against property: thefts of private property and breaking and entering of private buildings where the “dark numer” is high. Therefore, the distribution of crime in Warsaw is determined by offences against property where evaluation of the numer of  undetected offences is particularly difficult. As follows from the police data, the clearance rate of crime in Warsaw was differentiated according to both type and site of the offence. The highest mean clearance rate was found in Ochota district (27.5%), and the lowest in Praga Północ (16.3%). The probability of successful detection was highest with respect to traffic offences (0.93) and lowest in cases of breaking and entering (0.05). Clearance rate was highly differentiated (57%) in the case of car burglaries. The relatively highest probability of detection was found in Wola district (0.16), the lowest ‒ in Żoliborz (0.033) and Śródmieście  (0.038). The probability of detection of offences against persons in Warsaw in 1992 was about 0.6 (e.g. 60%), and against property – several per cent. The differentiation of both the dynamics and structure of crime in the separate districts of Warsaw and in areas of the separate police stations within the districts again confirms the thesis as to existence of areas that are particularly threatened with crime – the crime-generating areas. On the other hand, this differentiation suggests a large and indefinite numer of unrevealed or unrecorded offences. The present analysis, part of a study on the state of safety in Warsaw  initiated by the Superintendent of Warsaw Police and the Major of Warsaw,  confirmed the need for improving the data gathering system, securing the continuity of data, and the use of computer data carriers.

Opis:
In search for new markers of insulin-dependent diabetes (IDDM) susceptibility we studied the CATT tetranucleotide repeat in intron 1 of tyrosine hydroxylase (TH) gene on chromosome lip, the CA repeat at T-cell receptor a chain (TCRA) locus on chromosome 14q and two CA repeats at D10S211 and D10S213 loci in the chromosome 10 region containing glutamic acid decarboxylase (GAD2) gene. Alleles at these microsatellite loci were identified in a population of diabetic children and unrelated healthy controls originating from Wielkopolska, a midwestern region of Poland. We found significant association of certain alleles at TH, TCRA and D10S211 loci with diabetes in the population under study. On the contrary, none of the alleles at D10S213 locus was associated with the disease. Our findings indicate that typing of microsatellite markers may represent useful additional tool for identifying individuals at high risk of developing IDDM. Regarding loci on chromosome 10 our data and data published by other authors may suggest the extistence of two separate regions of association with IDDM susceptibility on this chromosome.

Opis:
This chapter contains analysis of questionnaires data base which was built by selecting one of several qualitative characteristics formulated with relation to each of the issues included in the questionnaire. The subject of examination is a set of multi- profile elements. In the initial part of the chapter, a method of division of such a set of objects into subsets including similar objects has been presented. Similarity of the objects is the basis for describing a function of distance between them. Then, by analyzing values of distance function, the entire set is divided into clusters. Research premise is executed in two sections. By calculating the distance between characteristics of analyzed phenomenon, which are represented by items in the questionnaire, a group of similar features - or lack of relationship between features - are determined. Second facet of the analysis consists in determining the distances of multi-profile objects from fixed standards, and division of the set of objects into homogenous layers. In paragraphs that follow, results of research conducted using the above method, and concerning changes in economic situation of Polish construction industry in 1993 - 1997 are shown. On the basis of the questionnaire data from the Institute of Economic Development and obtained from construction enterprises, mutual relationships between measures of economic situation have been examined. Moreover, changes in economic situation of construction enterprises in comparison to their distance from standards of economic situation have been analyzed, both in the entire population of enterprises and in two sectors of construction industry: private and public.

Opis:
Five newly synthesised monophosphates of two pyrimidine acyclonucleoside series, namely 1-N-[(2’-hydroxy)ethoxymethyl] and l-N-[(l’,3’-dihydroxy)- 2’-propoxymethyl] derivatives of 5- and 5,6-alkylated uracils were tested in vitro for chromosome aberrations and sister chromatid exchanges (SCE). Metaphase plates were obtained via microculture of human lymphocytes from heparinized peripheral blood. The compounds were tested in doses: 10, 20, 40, 80 and 150 µg per mL of culture. The tested compounds induced mainly chromatid gaps, less frequently chromosome gaps. A low number of mitoses with chromatid and chromosome breaks, acentric fragments, dicentric chromosomes and exchange figures were also observed. The tested compounds in doses: 40, 80 and 150 µg per mL, doubled or tripled the percentage of cells with chromatid gaps and chromosome gaps as compared to the control. The percentage o cells with aberrations (excluding gaps) induced by the tested compounds in all doses did not exceed 2%. The tested compounds induced a higher number of SCE per cell but less than double frequency as compared to the control. SCE frequencies and replication index (RI) values varied depending on the examined compounds. For the highest dose of the tested compounds (150 µg per mL) a significant decrease in RI values was observed for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-tetramethyleneuracil monophosphate and for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-dimethyluracil monophosphate. So far, the results have indicated potential clastogenicity of all the tested compounds except acycloguanosine monophosphate.

Two important chemical features of therapeutic waters from 57 intakes in 13 Sudetic health resorts, i.e. total dissolved solids (TDS) and bicarbonate ion (HCO3-) content, tested with the Kolmogorov test at the significance level α=0.05, during the whole exploitation period, reveal normal distributions. It bears evidence of little variability of these features. Intervals of the most frequent (normal) [HCO3-] content values in individual intakes, determined using the three standard deviations method (3σ) are in most cases concordant with real values. These intervals can be used for verification of monitoring measurements (elimination of incorrect determinations) and/or can indicate sudden changes of chemical composition of exploited therapeutic waters.
Dwie podstawowe własności wód leczniczych w 57 ujęciach z 13 miejscowości uzdrowiskowych Sudetów: suma substancji rozpuszczonych (TDS) i zawartość jonu wodorowęglanowego (HCO3-), przetestowane testem Kołmogorowa na poziomie istotności α=0.05 na przestrzeni całego okresu eksploatacji, wykazują rozkłady normalne, co świadczy o ich dużej stałości. Wyznaczone metodą trzech odchyleń standardowych (3σ) przedziały wartości najczęściej występujących dla zawartości (HCO3-) w poszczególnych ujęciach pokrywają się zwykle z wartościami rzeczywistymi. Uzyskane przedzialy normalnych zawartości anionu wodorowęglanowego mogą być wykorzystywane do weryfikacji prowadzonych obserwacji stacjonarnych (eliminowanie błędnych oznaczeń) i/lub sygnalizacji gwał- townych zmian skladu chemicznego eksploatowanej wody leczniczej.

Opis:
Results of business activity tests are characterized by very strong structural variation. Complex, multidimensional structure of population of enterprises being considered is the main source of diversity. Dynamic approach introduces periodical variation in values of certain variables, intensity of observed processes, and quality of ex post predictions. For instance, in construction industry, one factor which introduces the largest variation is the criterion of ownership. Also for industrial enterprises and trading companies, the largest differences are observed between groups of public sector and private sector enterprises. For the purpose of analysis of business activity tests results, traditional statistical methods may be used. In this chapter we introduce point estimators and interwal estimators of balances and business activity indicators. We consider the problem of aggregation of balances and define distribution of aggregated balances and its main moments. We present a construction of a significance test with test statistics A which has asymptotically normal distribution. The test measures significance of differences of business activity indicators between selected structural groups. We list assumptions necessary to obtain probability distributions of appropriate variables and show the most important properties of these distributions. Applications of proposed statistical analysis methods are described using construction industry activity data for Poland and Italy. As an example of conclusions drawn for Poland, we found strong correlation between assessments of business activity and sociopolitical conditions, as well as unfair treatment of different groups of business enterprises by central administration. Analysis of seasonal variation of construction industry activity confirmed legitimacy of assumed business activity indicator. It is a leading indicator which precedes changes in economic situation by about 3 months. Results of business activity tests for Italian industry do not confirm existence of significant seasonal variation of business activity. Results aggregated over 30 years of conducting tests in Italy clearly indicate that in construction industry, unfavorable periods outnumber favorable ones.

Opis:
The problem of imperfect knowledge became crucial issue for many applications including economic applications. Rough set theory, proposed by Z. Pawlak (1982) is one of the existing approaches to understanding and manipulation of imperfect knowledge. This theory has attracted many researchers and practitioners all over the world, who contributed essentially to its numerous developments and applications. The aim of this chapter is to present preliminaries of rough set theory (including information systems and decision tables, indiscernibility, lower and upper approximations of sets, reducts, patterns) and application of rough set methods to the construction industry data analysis with respect to the economic conditions. We present some methods based on rough set approach for solution of the following problems related to the analysis of such data: - Extracting dependencies between queries in questionnaires. - Searching for relationships between respondent answers and classification. - Extraction of (minimal) relevant subsets of queries predicting with high quality answers for other questions. Characterization of respondent situation changes in the consecutive year quarters. We discuss the results of Computer experiments including also visual representation of the received results.

W pracy dokonano analizy statystycznej metodą regresji wielokrotnej wpływu czynników meteorologicznych i glebowych na wartości temperatury radiacyjnej pokrywy roślinnej. Stwierdzono, iż wprowadzenie do modelu regresji wielokrotnej potencjału wody glebowej jako zmiennej niezależnej poprawia dokładność predykcyjną modelu w przypadku, gdy zmienną zależną jest różnica temperatury pokrywy roślinnej w sytuacji stresu wodnego i przy nieograniczonej dostępności wody glebowej. Przedstawiono zależność temperatury powierzchni roślin od temperatury powietrza, prędkości wiatru, radiacji słonecznej i potencjału wody glebowej.
In this study the statistical analysis was performed, using the multiple regression, of the impact of meteorological and soil parameters on radiation temperature of plant cover. It was stated that including into the model soil water potential as an independent variable of multiple regression, improves its predictive precision in case when the dependent variable is the difference of crop temperature in the conditions of water stress and under unlimited availability of soil water. The relation between crop temperature and air temperature, wind speed, solar radiation and soil water potential is presented.
