Opis:
The article presents a selection of indexes describing financial standing of local government units based on counties of the Wielkopolskie province. On the basis of their values analysed local government units were classified using Ward‘s method to form classes with a similar financial situation.
W artykule dokonano oceny sytuacji finansowej powiatów województwa wielkopolskiego. W analizie wykorzystano dane Ministerstwa Finansów oraz Głównego Urzędu Statystycznego z lat 2004-2006. Na podstawie przesłanek merytorycznych i statystycznych dokonano wyboru wskaźników sytuacji finansowej jednostek samorządowych. Stosując metodę Warda sklasyfikowano badane jednostki w siedem klas o podobnej sytuacji finansowej. Najlepsza sytuacja finansowa charakteryzowała powiat poznański oraz powiaty: grodziski, kaliski, koniński, leszczyński i nowotomyski, najgorsza zaś samorządy: czarnkowsko-trzcianecki i pleszewski.

Opis:
The article presents the evaluation of the financial situation of commercial banks in Poland. The ratio analysis shows that the biggest variations between analyzed units were in productivity of tangible fixed assets, share of non-performing loans and overall liquidity. The financial indicators constituted the basis for the process of grouping banks into clusters of similar financial standing. The use of Ward method enabled us to differentiate five clusters. The most profitable banks belong to the first cluster, while the most productive ones are from the fourth cluster. The third cluster comprises the banks with the relatively worst financial situation.

Opis:
The aim of the study: Analyse the causes of children sent to cardiologic consultations during the duty. Material and methods: The study group consists of 432 children (226 girls and 206 boys, average 9.8 years), which in 2009-2010 were sent from emergency ward to cardiac consultation. The basic study of the circulatory system was performed: physical examination, electrocardiogram and echocardiogram. In some patients there were additional blood samples for laboratory tests and chest radiographs performed. The results were analysed in age groups (infants, younger children and older children) as well as in the category of symptoms that were the reason for referral (syncope, fainting, chest pain, symptoms of heart defects, arrhythmia, hypertension). Results: The most common group were older children (257 cases – 60%) and sequentially 96 younger children (22%) and 79 infants (18%). In the category of symptoms the most frequent cause of cardiologic consultation of older children were fainting (which was found in 126 patients – 30% among all directed to the consultation) and the chest pain that occurred in 109 children (23%). In the youngest group the most common congenital heart disease was suspected. Other symptoms such as hypertension, arrhythmia, and myocardial disease occurred less frequently. Conclusions: The heart defects were the most common cause of referrals to cardiology consultation in infants group, while in the group of older children the main cause of referral were fainting and chest pain. Urgent hospitalisation was required only by more or less 10% of patients referred for cardiac consultation, within infants who required it five times frequently than children over 10 years of age.
Cel pracy: Analiza przyczyn skierowań dzieci na konsultacje kardiologiczne w trybie dyżurowym. Materiał i metody: Badaniem objęto 432 dzieci (226 dziewcząt i 206 chłopców, średnia wieku 9,8 roku), które w okresie 2009-2010 zostały skierowane z oddziału ratunkowego na konsultację kardiologiczną. Przeprowadzono podstawowe badania układu krążenia: badanie fizykalne, elektrokardiograficzne, echokardiograficzne, a u niektórych dodatkowo pobrano krew w celu przeprowadzenia badań laboratoryjnych oraz wykonano badanie radiologiczne klatki piersiowej. Dokonano analizy w kategorii wiekowej (niemowlęta, dzieci młodsze, dzieci starsze) oraz w kategorii objawów, które były powodem skierowań (omdlenia, zasłabnięcia, ból w klatce piersiowej, objawy wady serca, arytmia, nadciśnienie tętnicze). Wyniki: Spośród analizowanych 432 pacjentów w poszczególnych grupach wiekowych było odpowiednio: 79 niemowląt (18%), 96 dzieci młodszych (22%) oraz 257 dzieci starszych (60%). W kategorii objawów najczęstszą przyczyną skierowań dzieci starszych były omdlenia, które stwierdzono u 126 pacjentów (30% wszystkich skierowanych na konsultację), a następnie bóle w klatce piersiowej, które występowały u 109 dzieci (23%). W grupie najmłodszych najczęściej podejrzewano wadę wrodzoną serca. Pozostałe objawy, takie jak nadciśnienie tętnicze, arytmia, choroby mięśnia sercowego, pojawiały się z mniejszą częstością. Wnioski: Najczęstszą przyczyną skierowań na konsultacje kardiologiczne w grupie niemowląt było podejrzenie wady serca, z kolei w grupie dzieci starszych – omdlenia i ból w klatce piersiowej. Hospitalizacji w trybie pilnym wymagało zaledwie około 10% pacjentów kierowanych na konsultacje kardiologiczne, przy czym niemowlęta wymagały tego pięciokrotnie częściej niż dzieci powyżej 10. roku życia.

Opis:
The hospital environment is particularly predisposed to developing infections. The aim of the study was to determine the antimicrobial susceptibility of 52 strains isolated from the urology ward environment and to determine their polymorphism. Microorganisms present in the air were determined by sedimentation, and microbial surface was studied using contact plates. After identifying, the strains were assessed for susceptibility using disc diff usion method. Most strains were isolated CNS – 43 strains (82.69%), among which was the most numerous species of S. haemolyticus (14 strains – 32.6%), 21 CNS strains (48.8%) were resistant to methicillin (MRCNS). None of S. aureus was isolated from the environment. The greatest effi cacy against staphylococci showed netilmicin (97.7%), vancomycin (95.3%) and amikacin (93.0%). Most CNS were resistant to erythromycin (37.2% sensitive strains), trimethoprim with sulfamethoxazole (46.5% sensitive strains) and cefoxitin (methicillin – 51.2% sensitive strains). Staphylococci from the air were associated with less antibiotic resistance than those isolated from the test surface. Furthermore, out of the urology ward environment were isolated 6 strains of non-fermenting rods, and 3 strains of Enterobacteriaceae. All strains of non-fermenting rods were sensitive to gentamicin, tobramycin, and netilmicin. The lowest effi cacy had a combination of ampicillin with sulbactam (83.3% resistant strains). Rods of the Enterobacteriaceae family were susceptible to piperacillin with tazobactam, imipenem, ciprofl oxacin, amikacin, netilmicin, tobramycin, chloramphenicol and tetracycline. The least eff ective drugs were: trimethoprim with sulfamethoxazole, amoxicillin with clavulanic acid, cefotaxime, and cefamandole. Strains belonging to the same species showed, in most cases, diff erent susceptibility profi les. Identical susceptibility profi le, despite diff erent sites of material collection, occurred in two strains of S. haemolyticus and two strains of Pseudomonas spp, which may indicate their common ancestry. Continuous monitoring of the susceptibility, both clinical strains and those isolated from hospital environment and the rational use of antibiotics is necessary in order to reduce the growing bacterial resistance to commonly used antibiotics.
Środowisko szpitalne jest szczególnie predysponowane do rozwoju zakażeń. Przeprowadzone badania miały na celu określenie wrażliwości na antybiotyki 52 szczepów wyizolowanych ze środowiska oddziału urologicznego oraz określenie ich polimorfi zmu. Drobnoustroje pochodziły z powietrza pobranego metodą sedymentacyjną oraz z powierzchni przebadanych metodą kontaktową, z użyciem płytek odciskowych. Zidentyfi kowane szczepy poddane zostały ocenie lekowrażliwości, z zastosowaniem metody dyfuzyjno-krążkowej. Najczęściej izolowano szczepy koagulazoujemne z rodzaju Staphylococcus (CNS – coagulase-negative Staphylococci) – 43 szczepy (82,69%), spośród których najliczniej reprezentowany był gatunek S. haemolyticus (14 szczepów – 32,6%), 21 szczepów (48,8%) CNS było opornych na metycylinę (MRCNS – methicillin resistant coagulase- negative Staphylococci). Nie wyizolowano ze środowiska żadnego S. aureus. Największą wrażliwość wobec gronkowców wykazywały netylmycyna (97,7%), wankomycyna (95,3%) i amikacyna (93,0%). Najwięcej CNS było opornych na erytromycynę (37,2% szczepów wrażliwych), trimetoprim z sulfametoksazolem (46,5% szczepów wrażliwych) i cefoksytynę (metycylinę – 51,2% szczepów wrażliwych). Gronkowce pochodzące z powietrza charakteryzowały się mniejszą opornością na antybiotyki niż wyizolowane z badanych powierzchni. Ponadto ze środowiska oddziału urologicznego wyizolowano 6 szczepów pałeczek niefermentujących i 3 szczepy pałeczek należących do rodziny Enterobacteriaceae. Wszystkie szczepy pałeczek niefermentujących były wrażliwe na gentamycynę, tobramycynę i netylmycynę. Najmniejszą skuteczność miało połączenie ampicyliny z sulbaktamem (83,3% szczepów opornych). Pałeczki z rodziny Enterobacteriaceae były wrażliwe na piperacylinę z tazobaktamem, imipenem, cyprofl oksacynę, amikacynę, netylmycynę, tobramycynę, chloramfenikol i tetracyklinę. Najmniej skutecznymi lekami okazały się: trimetoprim z sulfametoksazolem, amoksycylina z kwasem klawulanowym, cefotaksym i cefamandol. Szczepy należące do tego samego gatunku wykazywały w większości przypadków różne wzory lekowrażliwości. Identyczny wzór lekowrażliwości, mimo różnego miejsca poboru materiału, występował u 2 szczepów S. haemolyticus i 2 szczepów Pseudomonas spp., co może świadczyć o ich wspólnym pochodzeniu. Ciągłe monitorowanie lekowrażliwości, zarówno szczepów klinicznych, jak też izolowanych ze środowiska szpitalnego, oraz stosowanie racjonalnej antybiotykoterapii jest konieczne w celu ograniczenia narastającej oporność bakterii na powszechnie stosowane antybiotyki.

W pracy przedstawiono ocenę stabilności klasyfikacji województw Polski pod względem poziomu życia w latach 2002-2009. Dobór cech diagnostycznych został przeprowadzony w sposób dynamiczny, dzięki czemu otrzymany zestaw cech końcowych jest aktualny nie tylko w okresie badanym, ale także w przyszłości. Do klasyfikacji województw zastosowano metodę Warda oraz sprawdzono dopasowanie dendrogramów do macierzy odległości D za pomocą współczynnika korelacji kofenetycznej, wskaźnika całościowego dopasowania i miary STRESS. Wykorzystując wskaźniki podobieństwa wyników klasyfikacji stwierdzono, że klasyfikacje charakteryzują się dość dobrą stabilnością w czasie.
The work presents evaluation of the results stability of the Polish regions’ classification in terms of a living standard. The research covered the period 2002-2009. Selection of diagnostic features was carried out in a dynamic way, so that the final set of features is valid not only in the period considered, but also in the future. For the regions’ classification Ward’s method was used and the fit of dendrograms distance to matrix D was checked by using the cophenetic correlation coefficient, the indicator of the overall fit and the STRESS measure. Using the similarity indices of the classification results, it was found that the classifications have a fairly good stability in time.

Streszczenie (jęz. angielski) - The paper presents an attempt to use both quantitative and qualitative veriables to analyze complex phenomena. First part of the paper focuses some normalisation methods that often occur in empirical works regarding their characteristics. Special attention concerns zero unitarization method due its adequacy in normalising both quantitative and qualitative veriables. The latter part of the paper presents the metod of quantification and normalization chosen qualitative variables. The whole procedure of normalization, construction of synthetic variable and ranking is illustrated by empirical example. Results of research on the competitiveness of communes in Lubelskie voivodeship consented with the use of multi dimensional methods are presented in the article. Two methods: Hellwig development pattern and Ward aggregation analysis were used in the work. The Hellwig pattern method enable the classification of communes according the level of competitiveness while Ward aggregation analysis is helpful for classification of communes according variables used in research Results of research on the competitiveness of communes in Lubelskie voivodeship consented with the use of multi dimensional methods are presented in the article. Two methods: Hellwig development pattern and Ward aggregation analysis were used in the work. The Hellwig pattern method enable the classification of communes according the level of competitiveness while Ward aggregation analysis is helpful for classification of communes according variables used in research The aim of the study was to show the analogy in the changes in the structure of household expenses in the chosen EU countries and Poland between1988 and 2009. The direction and pace of the changes in the budgets of Polish households can be predicted by using the principle of analogy. Classification of the objects has been carried out based on the modified kmeans method. Three classes of similarities have been distinguished. The structure of Polish households budgets from 2004 – 2008 has turned out the most similar to the structure of the expenses of Portuguese households from 1988 – 2005. In this work we analyzed the changes of the structure of value of agriculture products’ exports in Poland during 1980 – 210 in comparison to other EU countries. In this comparative analysis we chose those EU countries whose largest fraction of exports is constituted by agriculture products: Germany, France, Great Britain, Netherlands, Spain and Italy. To study the changes of the structure of export of agriculture products during those 31 years we used multidimensional analysis methods: Gini index and GCCA – Grade Correspondence Cluster Analysis. To visualize the differentiation of structures of export of agriculture products we used overrepresentation maps (prepared in GradeStat). Analysis was based on 9 groups of agriculture products in million USD: live animals (S2-00), meat and preparations (S2-01), dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), cereals and cereal preparations (S2-04), vegetables and fruit (S2-05), suger, suger preparations and honey (S2-06), coffee, tea, cocoa, spices, and manufactures thereof (S2-07), feeding stuff for animals (not including unmilled cereals (S2-08), miscellaneous edible products and preparations (S2-09). The completed studies have shown a large differentiation of the structure of export of agriculture products in all researched countries. However, the largest differentiation was present in Poland. A significantly high dynamic of growth was observed within three groups of products: dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), vegetables and fruit (S2-05). The participation of those groups in the country’s export has been steadily growing. On the other hand, the participation of until now standard groups of agriculture products (unprocessed: live animals (S2-00) and meat and preparations (S2-01)) has been decreasing.

To visualize the differentiation of structures of export of agriculture products we used overrepresentation maps (prepared in GradeStat). Analysis was based on 9 groups of agriculture products in million USD: live animals (S2-00), meat and preparations (S2-01), dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), cereals and cereal preparations (S2-04), vegetables and fruit (S2-05), suger, suger preparations and honey (S2-06), coffee, tea, cocoa, spices, and manufactures thereof (S2-07), feeding stuff for animals (not including unmilled cereals (S2-08), miscellaneous edible products and preparations (S2-09). The completed studies have shown a large differentiation of the structure of export of agriculture products in all researched countries. However, the largest differentiation was present in Poland. A significantly high dynamic of growth was observed within three groups of products: dairy products and birds’ eggs (S2-02), Fish, crustacean and molluscs, and preparations thereof (S2-03), vegetables and fruit (S2-05). The participation of those groups in the country’s export has been steadily growing. On the other hand, the participation of until now standard groups of agriculture products (unprocessed: live animals (S2-00) and meat and preparations (S2-01)) has been decreasing. The paper presents an investigation within the subject of fuzzy methodology concerning some phenomena, which is the consequence of their fuzzy nature. In order to illustrate some fuzzy procedures and their results an empirical example is included. The paper presents the forecast of agrarian structure of voivodships up to 2020 according to typological groups. The data were taken from Statistical Yearbook of Agriculture edited by Central Statistical Office. The forecast was based on the method of structures’ forecasting proposed by Nowak. Then, on the basis of fuzzy classification method, the prediction of spatial differentiation of the structure under investigation up to 2020 was evaluated. The forecast presents what kind of changes in agrarian structure of voivodships will take place if the direction and rate of changes within the period of 2002 – 2009 remain stable. Investments of local communes are intentional expenditures of capital aimed at increase in tangible and intangible benefits of the commune. All effective expenditures born by the commune on construction and reconstruction of its wealth are treated as funds positively influencing its development and well-being of citizens. The paper was intended to assess the level of dispersion, i.e. concentration of expenditures on investments born by 19 cities acting as counties in Silesian voivodship. The fundamental measure used in research was concentration coefficient proposed by Karol Kukuła and the basis for calculations was data presented in budget usage collected by Regionalna Izba Obrachunkowa in Katowice. The regression theory involves methods and tools of exact description of relations between various types of phenomena. Since many years, it is used for the economic and econometric models formulation, however, as the analyze of literature indicates, regression is understood in different ways. This article is a reflection on the application of quantitative methods in economics processes modeling, with particular emphasis on the relations between them, expressed by regression.

The article shows the practical application of the Analytic Network Process in solving decision problems from the field of management. The ANP Model proposed in this paper includes all kinds of dependencies and feedback between decision-making elements in the area of manufacturing management, reflecting the complexity of the problem and actual compounds that occur both between the agents within the company as well as in its surroundings. The paper emphasises the possibility of using experts’ opinion, who gave importance (specifying the validity) of decision-making elements using pairwise comparisons, allowing the identification of factors and the evaluation of their impact on the increase in the volume of production.

Entering into European Union and financial markets crisis left their stamps on Polish economy. Land market was influenced by these changes the most significantly since December 5, 1989, when new regulations concerning free transactions in land appeared. In the nineties farmland was treated as an additional superfluous ballast, however, together with Polish accession to EU it became one of the most popular alternative investments bringing profiteers huge profits in short term. Unfortunately, financial crisis trundling on the real estate market sadly revised investors’ optimistic plans. Abortive investments in too expensive lands without possibility of being transformed into building terrains became problems to people without appropriate knowledge and skills who had wanted to earn quickly. Currently, despite of spreading fashion of land purchase, the market has been weakened significantly. It can be admitted that finally the farmers instead of profiteers are interested in land purchase, which is the beginning of situation stabilization and the first sign of market maturity. Calculus of variations and optimal control theory are on one hand side intensively developing mathematical theories on the other at the center of both of them lies investigating of extremal problems. In connection with extremal problems there naturally arise questions important for mathematics and applications: 1) does there exist a solution of the problem? 2) is the solution unique? 3) how to really find the solution? For problems with constrains, a general principle was proposed by Lagrange. This idea can be generalized far beyond the limits of the problems that he considered. In the paper we present unified formulation of problems of calculus of variations and optimal control in connection with Lagrange principle. There is a 5:1 ratio between the number of households and business entities. This ratio is considered “quantum satis”. The purpose of this paper is to estimate level of local government unit’s financial independence in eastern Poland. For this purpose it was used multidimensional statistical analysis allowing to describe complex effect with help of one variable, so called value of synthetic variable (Hellwig’s method, additive aggregation function).

A number of recent papers on the management of the stock portfolio describes the advantages of the naïve diversification. The naïve strategy performs similarly to the ones which use sophisticated mathematical models. In this paper the strategy is presented which statistically significantly overperforms the naïve strategy. The aim of the paper was to make an attempt to assess the influence of belonging to selected population groups on the size of flows between different states of economic activity, as well as to determine the nature of unemployment found in the various population groups, especially among the rural population. The research showed that the changes in economic activity are mainly affected by structural factors, but in some population groups it is possible to improve the employment situation through actions towards an improvement of the prosperity on the market of goods and services.

Dynamic development of organic farming in Poland is observed since 2004. At that time were introduced the subsidies to organic agricultural production for farms with the certificate of conformity and were in the course of the changes. The aim of this study is to present the dynamics of growth of the number and size of organic farms and the number of organic ecological factories in Poland in the years 2004-2010 and the designation of the forecasts for the next three years. To designate the forecasts of investigated phenomena it was used extrapolation of models of development trends method. In this paper we discuss the development of the rural population in Poland over the past 60 years and the latest demographic projections of Central Statistical Office. The main objects of our attention are the demographic processes in rural-urban cross-section. Poland belongs to the less urbanized countries in Europe. Among Polish neighbors, a lower proportion of urban population is only in Slovakia. However, in the past, differences in the level of urbanization between Poland and other European countries were much higher. In the years 1950-1990 the percentage of urban population in Poland increased from 35 to 62%. However, since 1990. share of rural population has ceased to fall and in the last few years have seen a decline in urbanization even in our country. The main reason for the change is a systematic change in the directions of rural-urban migration. More and more urban population moves to the village. Quite interestingly, this process began much earlier than the changed political system in Poland. Since 1975. decreases systematically negative balance of net rural-urban migration. Since 2000. more and more of the population migrates to the country than comes out. We also pay attention that a similar phenomenon of the growing importance of the share of rural population also occurs in other countries. However, while Poland is following the European countries also in the sphere of customary transformation, the village population seems to be the mainstay of traditional family values.

In this article, the problem of optimization of crop production was formulated as nonlinear generalized transportation problem. As a solution the author proposed generalized quasi-basis method. The illustrative example completes the presentation. The study exemplifies an application of the multidimensional comparative analysis aiming at quantification of international competitiveness of the agri-food economy. The international competitive position was equated to a form of a synthetic measure. The coefficients trends allowed quantifying perspectives of equalization of international competitiveness levels between countries. The empirical investigation identified six patterns of the observed interdependences. Convergence should not be expected in the whole set, but in subgroups of objects. In the light of the Central Statistical Office data from 2010, farm equipment is shows very high differentiation in spatial aspect across Poland. The paper presents an attempt to construct ranking of voivodships with respect to the level of farm equipment. On the basis of zero unitarization method different variables are compared and used to form the synthetic variable. In consequence, three groups of districts were distinguished: of high, moderate and low level of farm equipment. This work is devoted to discussions on application of relative measures of accuracy of the ex-post forecasts. The authors showed that when the variable has a very large amplitude of seasonality indicators the average absolute forecast error (MAPE) can not be used. Theoretical study are illustrated on the example of thermal energy production. This work is devoted to discussions on application of relative measures of accuracy of the ex-post forecasts.

Decomposition of price time series was performed using method Census II/X11. Price of broiler chicken livestock characterize stable an stronger in recent years seasonality. In 2011 the seasonal index was ranged from 107,3% in August to 92,2% in December. In the range of six month more than half of price variability (51,4%) is a result of long period changes, 44,9% of variability is shaped by seasonal fluctuations and only 3,7% is made by irregulars fluctuations. In this paper, the rankings of the food industry sector companies listed on the Warsaw Stock Exchange were made on the basis of Taxonomic Attractiveness Measure of Investment. The following groups of variables were included in this study: liquidity ratios, profitability ratios, debt ratios, activity ratios, market-based ratios. Then analyzed whether the positions in the rankings of investigated companies remained stable over the period 2009-2011.

The article focuses on trade between Japan and Poland, in 2000-2010 years, using the SITC (Standard International Trade Classification), identifying trends occurring among one of classification group: Food and live animals. Analysis of exports and imports between Japan and Poland shows big changes in trade with Japan and the large growing difference in the trade balance. Furthermore the imported and exported groups of products show market differences and demand in Japan. The paper presented classification of voivodships due to the selected financial data business accommodation and catering department. For this purpose it was used the multidimensional statistical analysis allowing describe complex effect with help of one variable, so called value synthetic variable. Among the factors that impact the absorption of European Union funds in Polish agriculture, natural, demographic, technical and organisational conditions of the development of agriculture can be differentiated. The basic objective of the article is to identify and quantify the factors, which significantly impact the territorial differentiation of the absorption of European Union Funds in Polish agriculture within the framework of the “Modernisation of agricultural holdings” Rural Development Programme for 2007-2013.

The wage effects of student numbers on particular fields of study in Poland are analyzed. It is found that any of the fields of study, i.e. humanitarian, business and economics, technical or natural sciences, contributes to an increase in wages on the macroeconomic level, but the whole effect is smaller for studies in economics, which could be an outcome of too high interest in that kind of education. On the other side, our results for technical studies could be viewed as an argument in favor of an excess labor market demand for engineers compared to their supply by the educational system.

Opis:
Celem opracowania była próba delimitacji krajów w UE-27 o podobnej strukturze i skali pro-dukcji pochodzącej z gospodarstw rolnych. W badaniu położono nacisk na uwypuklenie po-dobieństwa struktur produkcji typowych dla obszarów klimatycznych UE-27 w 2008 roku, a także na wskazanie klasy, do której zakwalifikowano polskie rolnictwo. Wykorzystano dane z bazy FADN, którymi były średnie ważone przeliczone na gospodarstwo rolne z 27 krajów członkowskich UE w 2008 roku. Delimitację wykonano w oparciu o strukturę produkcji, wielkość ekonomiczną, powierzchnię użytków rolnych, wartość produkcji i dochodów z go-spodarstwa rolnego. Badanie wykonano za pomocą hierarchicznej klasyfikacji aglomeracyjnej metodą Warda. Przy czym strukturę produkcji reprezentowały 23 cechy, a pozostałe cechy były pojedyncze. Optymalną liczbę klas krajów o podobnej strukturze i skali produkcji wy-znaczono na podstawie analizy wielkości przyrostów wariancji wewnątrzklasowej w procesie łączenia klas między poszczególnymi poziomami łączeń. W ten sposób uzyskano 10 klas kra-jów. Klasy opisano według obliczonego miernika różnic średnich dla analizowanych cech.
The aim of the article was an attempt at delimitation of countries in the EU-27 with similar structure and scale of the production of farms. In this study, the emphasis is placed on high-lighting the similarity of production structures typical of the climate’s areas of the EU-27 in the year 2008, and also on indicating the class in which the Polish agriculture were classified. For this research, the data from FADN database was used. This database contains weighted averages per individual farm in every of 27 UE member countries in 2008. The delimitation were made based on the structure of production, economic size, agricultural utilized area, production and income of agricultural farm. The research was conducted using the agglomera-tion hierarchic classification based on the Ward’s method. The structure of production is rep-resented by 23 characteristics; the remaining characters are represented by single variables. The optimal number of classes of countries of similar structure and scale of production was estimated on the basis of the analysis of the amount of the intra-class variance’s increment. 10 classes of countries were obtained. These classes were described by the measure of the aver-age differences for analyzed characters.

Opis:
W opracowaniu przedstawiono typologię krajów Unii Europejskiej opartą na kryteriach dotyczących wartości eksportu w wybranych branżach usług oraz na ich udziale w całkowitej wartości usług eksportowanych z UE. Badanie wykonano z zastosowaniem metody analizy porównawczej, a grupy typologiczne krajów Unii Europejskiej wyodrębniono metodą Warda. Wskazano na wysokie obroty szczególnie w państwach wysoko rozwiniętych Europy Zachodniej oraz na dominujące znaczenie w strukturze zarówno eksportu, jak i importu usług, we wszystkich analizowanych branżach, Niemiec i Wielkiej Brytanii. Stwierdzono również, że nowe kraje członkowskie Unii Europejskiej z regionu Europy Środkowo-Wschodniej dotychczas w znaczącym stopniu nie wyspecjalizowały się w handlu usługami.
In her study, the author presented a typology of the European Union countries based on the criteria related to value of exports in the selected service industries and on their share in the total value of services exported from the EU. The research was carried out with application of the method of comparative analysis, while the typological groups of the European Union countries were selected by the Ward’s method. The author pointed out to high sales particularly in the highly developed states of Western Europe as well as to the prevailing importance in the structure of both exports and imports of services, in all the service industries in question, of Germany and the United Kingdom. She also ascertained that the new European Union Member States from the region of Central and Eastern Europe have so far not specialised to any significant degree in trade in services.
В разработке представили типологию стран-членов Европейского Союза, основанную на критериях, касающихся стоимости экспорта в избранных отраслях услуг, а также на их доле в совокупной стоимости услуг, экспортирумых из ЕС. Изучение провели, применяя метод сопоставительного анализа, а типологические группы стран-членов Европейского Союза выделили по методу Уорда. Указали высокий товарооборот в особенности в высокоразвитых странах Западной Европы, а также превалирующее значение в структуре как эскспорта, так и импорта услуг во всех анализируемых отраслях, Германии и Великобритании. Констатировали тоже, что новые страны-члены Европей- ского Союза из региона Центрально-Восточной Европы до сих пор в значительной степени не специализировались в торговле услугами.

Opis:
The diversity and multiplicity of information associated with investment in the stock market can cause problems with the proper understanding of the analyzed phenomena. In particular it refers to small investors who invest directly in stocks. Therefore, evaluating the financial condition of listed companies is very important, hence the need to use methods that will simplify and thus make stock market analysis easier. This paper presents an attempt to apply the selected financial ratios for the classification of 17 real estate companies listed on the Warsaw Stock Exchange into groups characterized by a similar economic condition. In the study multidimensional comparative analysis was used, i.e. Ward’s method and the method of k-means. The analysis was carried out in the period 2010-2012. In the experiment it was proved that using Ward’s method could identify companies with the weakest condition.
