Published: August 2017

Abstract. Historic districts are a special type of cultural heritage, as living cultural heritage, the utilization and development of historical districts is an inevitable issue. How to accurately position the protection and utilization of districts and achieve its healthy and sustainable development is the key work in the protection of districts. In this paper, the Internet data including Tencent’s location big data are employed to study some Chinese historic and cultural streets, establish protection and development index system for historic and cultural streets, carry out in-depth study of ten core indicators, and sum up the positioning and development direction for the protection and use of districts. Historic district, as a special type of cultural heritage, is the birthplace and supporting zone of urban context, and also the place for the daily life of the general public. It boasts profound historic and humanistic background and the characteristics of a living form. As the living cultural heritage, its use and development are necessary, and attention shall also be paid to static protection and dynamic comprehensive management. But judging from the current practice, protection and use of historic districts face a host of challenges. Some districts are devoid of popularity and vitality and become cold galleries. Some districts suffer excessive development for tourism and commercialism, and lose its “original” cultural characteristics. In addition, throngs of tourists exert a negative impact on the life of the local people and the protection of immovable cultural relics. Disorderly business format and increasingly similar landscape go against the presentation of local characteristics. We should regard historic district as a dynamic urban heritage, and achieve dynamic development and protection in accordance with its inherent development laws and the principle of “step by step” through the “organic update” mode, with emphasis on the continuous comprehensive management of material space environment and cultural society. Therefore, how to make accurate positioning of the protection and utilization of districts and achieve its healthy and sustainable development is the key work in the protection of districts.

Published: August 2017

Abstract. The mechanical interaction of propagating normal faults is known to influence the linkage geometry of first-order faults, and the development of second-order faults and fractures, which transfer displacement within relay zones. Natural examples of growth faults from two active volcanic rift zones (Koa’e, Big Island, Hawaii and Krafla, northern Iceland) illustrate the importance of relay zone heave gradients and associated vertical axis rotations in evolving continental rift systems. Detailed field mapping of deformation within two relay zones, located at the tips of en echelon rift faults, reveals pronounced heave displacement deficits that are accommodated by: (1) extensional-shear faults that strike at a low angle ( 45°) and accommodate a significant component of rift zone-parallel extension. Such extension parallel to the rift axis may oppose any shear-induced shortening that is typically required for vertical axis rotations (e.g. bookshelf faulting models). At the surface, this volume increase is accommodated by open fractures, but may be accommodated in the subsurface by veins or dikes oriented oblique- and normal to the rift axis. This proposal is consistent with data from exhumed contemporaneous fault and dike systems seen on the Faroe Islands and in Kangerlussuaq (East Greenland). Based on the findings presented here we propose a new conceptual model for the evolution of segmented continental rift basins on the NE Atlantic margins.

Atualmente, existem poucos estudos sobre a influência do vento no ambiente térmico exterior e no conforto térmico em áreas urbanas de clima subtropical. As atuações de ventos regionais típicos são de grande importância na interpretação de dados e na busca por respostas perceptivas e de sensação térmica da população. A presente pesquisa buscou por meio da análise de dados climáticos obtidos em campo, avaliar a sensação térmica e a percepção climática da população de Santa Maria-RS, sob influência do vento norte local, um vento regional típico que se caracteriza por ser quente e seco e soprar do quadrante norte em períodos de tempo pré-frontal. Para tanto, fez-se o uso de dados meteorológicos primários, a partir da instalação de uma estação meteorológica móvel no centro da cidade, bem como de dados meteorológicos secundários, provenientes da Estação Meteorológica de Santa Maria sob responsabilidade do Instituto Nacional de Meteorologia (INMET). Também foram executadas entrevistas com a população local, com a finalidade de obter as respostas perceptivas e de sensação térmica dos usuários que circulavam em ambiente urbano. Verificou-se uma influência negativa do vento norte na sensação térmica da maioria dos indivíduos entrevistados, bem como uma percepção desfavorável ao vento, o que resultou em sensação térmica de desconforto durante os dias em que as temperaturas estavam elevadas e o vento norte quente e seco mais intenso.

Os Kalunga, população afrodescendente, são povos tradicionais, que têm suas comunidades no Sítio Histórico e Patrimônio Cultural Kalunga, no Nordeste de Goiás. A atividade turística na comunidade dos Kalunga foi introduzida desde a década de 2000, com mais vigor na comunidade de Engenho II. A metodologia fez uso de consultas a sites, leituras de relatórios e dissertações sobre o tema e, a realização de entrevistas no procedimento da pesquisa-ação. Além de refletir sobre a inserção de turismo e seus impactos políticos, econômicos e sociais até na percepção dos Kalunga, considerou-se importante refletir o turismo local à luz do etnodesenvolvimento. Os resultados apresentados derivam de análise feita na comunidade Engenho II. Conclui-se que os Kalunga daquela comunidade concebem a atividade turística como promotora da melhoria de vida para alguns e há o interesse por esta atividade; contudo, a presença de turistas no Sitio não se deve ao etnoturismo, na opinião deles; atualmente, o turismo favorece o enriquecimento de alguns, agravando as fissuras sociais, as possibilidades de fortalecimento do turismo e de fazer a inclusão social dos Kalunga depende de um empoderamento da Associação. O etnodesenvolvimento nos Kalunga é a forma democrática, solidária de promover a socialização do trabalho e da renda advinda com o turismo.

Published: August 2017

A cidade de Campinas/SP, conhecida por sua pujança econômica, é composta também por uma extensa, diversa, fragmentada e empobrecida periferia urbana. Nesse artigo apresentamos parte de nossas pesquisas sobre o processo de urbanização de Campinas, enfatizando a periferização mais recente com início nos anos 1990 e marcada pelas ocupações de terras urbanas. Destacamos as duas maiores ocupações da cidade: a do Jardim Campo Belo e a do Parque Oziel, que somam hoje uma população de aproximadamente 80 mil pessoas. Ao longo das últimas décadas, os moradores dessas duas ocupações traçaram inúmeras ações para produzir e organizar uma fração da cidade de Campinas: construíram as habitações, edificaram igrejas e centros comunitários, distribuíram informalmente redes de energia e água. Seguiram lutando para ter acesso aos serviços públicos (transporte, saúde, educação) e, ao mesmo tempo, resistiram às constantes ameaças de desocupação. Buscamos aqui analisar e problematizar essas ações que permitiram a sobrevivência e a luta dessa população migrante, marginal e/ou excluída, considerando a) a formação do lugar; b) as ações das Associações de Moradores do Bairro; e c) a produção de informações ascendentes colocadas em circulação através de jornais locais e rádios comunitárias. Reconhecemos que nos limites da racionalidade dos sistemas econômico e político hegemônicos gestam-se contra-racionalidades, racionalidades paralelas, voltadas à sobrevivência, à reprodução e à resistência.
The Gurkhas and Great Inequalities in Their Lives
Authors: Wu Xiaoyu , Zhu Kui
Published: August 2017

The Nepalese Gurkhas have been in military service for the British more than 200 years and played an important role not only in helping the British exert its control over its colonials or protectorates, but also in securing some countries or keeping the world peace. However, these Gurkhas have not enjoyed their rights because of their unique identity. Therefore, this paper begins with the history of the Gurkha regiment, the martial race theory as well as the racist ideas on the Gurkhas. Then it turns to the great inequalities that the Gurkhas have experienced during their military service and after their retirement as well as in law & British court. Finally, it briefly covers reasons for Gurkhas’ inequalities and ways to eliminate the inequalities.

Purpose: of this paper is the assessment of the strength of binding of selected bondingsystems used for fixing prosthetic works. The characteristics of cement materials used forsettling the crowns on the implant abutments were also included. The study has presentedthe evaluation of the binding strength of selected bonding systems used for fixed prostheticworks.Design/methodology/approach: Metal substructures of single-unit cement-retainedcrown were designed and manufactured using CAD/CAM technology. Created wax modelswere changed to metal substructures and settled on the abutments attached to implantreplicas with a group of commonly used dental cements. The binding strength was testedon Zwick Z 100 static tensile testing machine.Findings: It was found that MaxCem is the strongest material among the tested cementswhich can withstand the force of 175 N. Double cured cements containing the resins maywithstand very high tensile strengths which can be a problem when the crown needs to betaken off. The bonding strength of the dental cements can be influenced by the width of thefilm, its thickness, even distribution of the cement between the crown and the abutment andthe setting time. The higher the viscosity of the cement, the lower the retention of the crownon the implant abutment.Research limitations/implications: In order to limit the designing and manufacturingerrors the whole technological process should be carried out with CAD/CAM technology.The cement should be evenly distributed inside the metal cup to prevent from creation ofempty spaces between the crown and the abutment. It may be necessary to design andmanufacture special holders to maintain the samples in the testing machine to minimalizethe risk of creation initial tensile forces.Practical implications: The research gives an insight into the possibilities of choosingthe cement for bonding the crown onto the implant abutment preserving the connectionbetween the bone and the implant in case of necessity of the removal of the crown.Originality/value: The research is focused on the binding strength of the cements mostcommonly used for settling the crowns on the implant abutments.

Officinalis
Authors: Prabaharan T. , Parithi M.
Published: August 2017

Purpose: Corrosion is the process of degradation of the materials due to its interactionwith the atmosphere. All materials are susceptible to corrosion. Among all other materialsmetals are the most widely used materials. Metals are widely used for their properties suchas high strength, ductility, thermal resistance and formability. So it is important to establishsuitable methods to inhibit the corrosion of such materials. In this paper the material mildsteel has been selected as it is one of the most commonly used material. The method usedfor corrosion inhibition is anodization followed by sealing using an ecofriendly corrosioninhibitor. The eco-friendly material that is tested in this paper is Emblica officinalis morecommonly called as Amla. The material is first anodized in a 50% NaOH solution at elevatedtemperatures and their corresponding corrosion inhibition is studied using weight lossmethod. Properties such as adhesion, heat resistance are also tested for the material. FTIRis used to identify the coating produced by anodizing and also for the identification of thefunctional bonds in the ecofriendly corrosion inhibitor.

Authors: Metin F. , Cengil M.
Published: August 2017

Purpose: In this study, short-term tensile creep and recovery behaviors of medical gradeultra-high molecular weight polyethylene (UHMWPE) were investigated to contributedeformation behaviour of UHMWPE components in knee and hip prosthesis during daily lifeactivities of patients.Design/methodology/approach: Tensile test specimens were machined fromcompression molded UHMWPE sheets having commercial brand name: Chirulen 1020 andthey were prepared according to ASTM 527-2. The tensile creep tests were performed atconstant stress levels of 5, 9, 13, 18 and 21 MPa as long as 1 hour for each test. Then, thespecimens were allowed to recover unloaded for 1 hour. Automatic extensometer was usedto measure the deformations precisely for each test.Findings: Results show that creep rate linearly increased with increasing the stress levels.Permanent deformations were observed after recovery. Recovery of the material becamedifficult with increasing the applied load at intended time interval.Research limitations/implications: UHMWPE components used in prosthesis havebeen subjected to complex loading conditions during service life. Polymeric materials showthe viscoelastic material properties like strain rate sensitivity, relaxation, creep and recoveryat room temperature. Because of the viscoelastic material properties of the UHMWPE,it makes difficult to predict the failure of the UHMWPE components in hip and knee prosthesis.Therefore, deformation behavior of medical grade UHMWPE should be investigated in manydifferent loading conditions.Practical implications: Medical grade ultra-high molecular weight polyethylene(UHMWPE) have been used commonly in total hip replacements as acetabular cup and intotal knee replacements as tibial insert since early 1960s.

Authors: Tański T. , Matysiak W. , Zaborowska M. , Łukowiec D. , Krzesiński M.
Published: August 2017

Purpose: The aim of this study was to produce poly(vinylpyrrolidone) (PVP) containingsilica nanofibers using electrospinning method from 10% PVP/EtOH solutions with differentmass concentration 0 and 30% of tetraethoxysilane. Sol-gel technique was used to obtainnanofiber membranes with high amount of inorganic phase. In the case when metal alkoxide,such as tetraethyl orthosilicate (TEOS) is mixed with an organic polymer, hydrolysis andcondensation reaction of TEOS occur in-situ with polymer matrix, which allows to fabricateorganic-inorganic hybrid structures with uniform dispersion.Design/methodology/approach: The examination of the morphology of the obtainedPVP/silicon dioxide nanofibers using scanning electron microscope (SEM) has been made.The chemical structure of produced nanostructures was investigated by Fourier - TransformInfrared spectroscopy (FTIR) and Energy Dispersive Spectrometry (EDX) to analyze theregular dispersion by examining types of bonds occurring between polymer matrix and SiO2phase.Findings: Results obtained in this paper shows that the mass concentration of thereinforcing phase in form of TEOS have an influence on the average diameter of nanofibersand with the increase of tetraethyl orthosilicate in solution nanofibers diameters decrease.Moreover, structural examination shows uniform dispersion of the reinforcing phase in hybridmaterials.Research limitations/implications: Uniform dispersion of the reinforcing phase insilica-containing PVP nanofibers gives the opportunity to make nanowires in calcinationprocess from such obtained fibrous mats and use in novel electrical devices.Originality/value: This paper describes an easy and more effective way of makingpolymer nanofibers with the content of silicon dioxide with the perspective way of makingsilica nanowires in the future from obtained hybrid nanofibers, so that this method canreplace commonly used nanowires growth processes.

Published: August 2017

Purpose: In this research work the nickel oxide incorporated zinc oxide nano compositewith various level of percentage such as (0.2, 0.4 and 0.6) were synthesized usingcombustion processes. Fuel used for the combustion process is hexamine in this work.Oxidizing agents taken were the nitrates of zinc and nickel. These precursor nitrates wereheated with hexamine fuel to undergo combustion process.Design/methodology/approach: After combustion the particles were collected and heattreated to maintain the purity of the samples. XRD results were in well accordance withthe JCPDS data and the average crystalline sizes were in the range of 10~20 nm. UV-VISabsorbance results confirm the band gap in the visible region. With increase in concentrationof NiO in the composite red shifted from 320 nm to 374 nm. FTIR supports the presenceof Zn-O and Ni-O bonds by the characteristic vibrational peaks at 432 cm-1 and 470 cm-1respectively. PL spectrum studies results in the redshift of ZnO peaks from 380 nm to 400 nmwith addition of Ni2+ ions inside the lattice. SEM and AFM studies reveals the morphologicaland topographical visualizations of the nanocomposite powders.Findings: In this research work, the authors had successfully synthesized Nickelsubstituted Zinc oxide by following simple combustion method followed by annealing. XRDanalysis clearly evidences the formation of ZnO in the hexagonal wurtzite structure with anaverage crystallite size of 15 nm to 18 nm. An increase in Nickel peaks in between the Zincoxide peaks were observed with increase in the nickel concentration in the composition.Practical implications: We conclude that combustion technique is suitable to fabricateNickel incorporated Zinc oxide particles with high purity. This powder can be used intransparent conducting thin flims for OLED applications.
Design of modernization of control valves
for the counter-bending forces regulation
in finishing mill
Authors: Evin E. , Tkáčová J. , Lengyel Z.
Published: August 2017

Purpose: The aim of this paper is design of modernization of control valves of finishing
mill to control the counter-bending forces on the last stands by replacement of proportional
valves with regulating ones.
Design/methodology/approach: New board (construction, location and arrangement
of valves) was designed, model of which was constructed by SolidWorks software.
Findings: The solution was oriented to optimization by replacement of proportional valves
for regulating ones to control the counter-bending forces on the rolling mills. The selected
types of proportional and regulating valves were compared. The main advantage of the
application of regulating valves is integrated electronics with position controller for pilot
valve control and position feedback disposal. Based on the parameters of the regulating
valve the new respite and relief valves were designed.
Research limitations/implications: Design of substitution of upper and lower
blocks of control valves and modelling the motherboards using SolidWorks software was
conditional by dimensions of currently used hydraulic components and dimensions of
the proposed valves. Designed blocks ensure the functioning of the control system of
counter bending of working rolls. In the future the perspective to control the counterbending
forces can be carried out by innovation of the rolling mill by pump control using
asynchronous converters and/or by changing the structure of the arrangement of rolling
mill and by design of CVC control of the rolling mill.
Practical implications: New board (construction, location and arrangement of valves)
was designed, model of which was constructed by SolidWorks software. Designed board
ensures the functioning of the control system for counter-bending of working rolls.
Originality/value: The result of the proposed solutions is increasing the quality of the hot
rolled strip i.e. reduction of the strip waviness and keeping the cross section of the strip.
Vacuum Shroud (VS) for production
of clean steel in tundish
Authors: Chatterjee D.
Published: August 2017

Purpose: Ladle to tundish melt transfer is paramount importance over the last three
decades to controlling the cleanliness of high value steel. Tundish is an important buffer
between ladle and mould where inclusion separation, flotation can be enhanced and
exposed slag eye formation can be hindered by applying the knowledge of fluid dynamics as
well heat transfer by changing the design of conventional flow modifiers towards production
of ultra clean steel.
Design/methodology/approach: In current numerical investigation a new conceptual
flow control device called ‘vacuum shroud (VS)’ has been proposed to reduce slag eye
formation, emulsifications and unwanted inclusions generations. Due to upward suction
force from the side of the pouring nozzle the device is quite capable to reduce turbulence
and emulsification within the tundish melt.
Findings: Approximately 76% improvement in the overall process and 40% enhancement
to inclusion floatability are predictable by using current flow control device (FCD).
Research limitations/implications: Slag eye formation during pouring of liquid steel to
tundish is a barrier to clean steel production on sustained manner. Several efforts have been
made over the decades to resolve this phenomenon by suppressing the turbulence within
this reactor incorporating many innovative flow control refractory’s like turbo-stop, trumpet
shroud, advance pouring box, dissipative shroud, velocity break shroud, swirling flow shroud
etc. But ultimate success is not possible to reach.
Originality/value: The present investigation is development of an innovative flow control
device (FCD) to control the aforementioned problems within this metallurgical reactor.

junction
Authors: Jarmoliński A. , Dobrowolski T.
Published: August 2017

Purpose: The purpose of this report is to present the similarities and differences between
modified sine-Gordon models used in description of the curved Josephson junctions.
The leading dynamical variable in this system is a gauge invariant phase difference of the
macroscopic wave functions of the superconducting electrodes that form the junction.
Findings: The main finding of this article is the observation that in the model used in
description of junctions with quickly varying curvatures the significant part of the kink energy
is confined in the curved regions of the junction.
Research limitations/implications: The paper is limited to the description of the
dynamics of fluxions in the long Josephson junctions. These junctions due to small
transverse sizes (smaller than the Josephson penetration depth) can be considered as a
one dimensional systems.
Practical implications: It seems that junctions with appropriate geometry will find
applications in future electronic devices. It is expected that curved Josephson junctions can
be used in order to store a binary data.
Originality/value: The main idea of the paper is to use a Riemann geometry in order to
describe the influence of the curvature on the kink motion in the junction.
The influence of burnishing parameters
on the hardness and roughness on the
surface layer stainless steel
Authors: Dyl T.
Published: August 2017

Purpose: The aim of the study was description to the influence of technological parameters
of burnishing process on the degree of relative strain hardening and surface roughness
reduction ratio.
Design/methodology/approach: Burnishing process carried out for stainless steels
X2CrNiMo17-12-2. After the experimental research, it was determined that there was an
increase in hardness and a decrease in roughness. The hardness was measured with the use of
Vickers hardness tester. Observation of the microstructure of stainless steel samples was carried
out using scanning electron microscopy and optical microscopy. The parameters of surface
roughness measurements were performed to the principles contained in ISO standards.
Findings: In the production and regeneration of metal products used in machine elements is
important to technological quality surface layer. In surface engineering one of the ecological
and economic treatments used for endurance and technological properties is burnishing.
This is a surface forming a local plastic deformation based on the overall impression given
by smooth and hard tool.
Practical implications: The burnishing due the technological and economic aspect in the
production and regeneration of machine parts in exchange for the abrasive processing can
be used. In production engineering or technology of repair cylindrical outer surfaces (e.g.
plugs propulsion shaft centrifugal pumps seawater) are finishing. You can therefore propose
burnishing in exchange for abrasive machining.
Originality/value: Important question to determine in the article of the research was to
received appropriate technological quality. After the tests, it was found that the technological
parameters are influenced by the hardness and the roughness of the outer cylindrical surfaces
and the material ratio curve a convex shaped, which, taking into account the load capacity of
the surface will be directly affected by its resistance to wear and corrosion of the surface layer.

Influence of gas boriding on corrosion
resistance of Inconel 600-alloy
Authors: Dziarski P. , Makuch N. , Kulka M.
Published: August 2017

Purpose: The aim of this study was to analyse the corrosion behaviour of gas-borided
layers produced on Inconel 600-alloy. Two types of the borided layers were produced: fully
borided and partially borided layer. The results obtained for gas-borided specimens were
compared to untreated Inconel 600-alloy.
Design/methodology/approach: In this paper, gas boriding in N2-H2-BCl3 atmosphere
was applied to produce the boride layers on Inconel 600-alloy. This process was carried
out at 910°C (1193 K) for 2 h. Microstructure observations were carried out using a light
microscope. The hardness measurements were performed using a Vickers method under a
load of 0.981 N. In order to evaluate the corrosion resistance, the immersion corrosion test
in a boiling solution of H2O, H2SO4 and Fe2(SO4)3 was used.
Findings: The gas-borided layers consisted of a mixture of nickel borides (Ni3B, Ni2B,
Ni4B3, NiB) and chromium borides (CrB, Cr2B). The high thickness of compact boride layer
(76-79 μm) as well as high hardness (up to 2061 HV) were obtained. Based on corrosion
resistance tests it was found that in case of untreated sample the strong intergrannular
attack was observed. Whereas the corrosion behavior ofgas-borided Inconel 600-alloy was
more complicated and resulted from the surface condition.
Research limitations/implications: The obtained results indicated that gas-boriding in
N2-H2-BCl3 atmosphere could be a suitable corrosion protection if the whole surface would
be covered with boride layer.
Practical implications: The parameters of gas boriding in N2-H2-BCl3 atmosphere used
in this study (temperature of 910°C for 2 h) allowed to produced layers of a higher thickness
in comparison with other acceptable method of boriding e.g. powder-pack boriding.
Originality/value: Based on the results it was found that gas-boriding in N2-H2-BCl3
atmosphere is a suitable method to protect Inconel 600-alloy from corrosion.

Authors: Czakowski Dariusz
Published: August 2017

The article presents the most important statistics and indicators related to the development of basic economic and financial categories of agricultural holdings, such as the productivity of individual factors, the level of profitability and the cost of production. Considerations have been made for agricultural holdings specializing in the production of basic agricultural products such as: cereals and oil, root crops (including potatoes and sugar beet), fruits, vegetables under the cover, beef cattle, pork, poultry, cow’s milk, chicken eggs. In turn, the comparison of the economic and financial results achieved using the Hellwig’s pattern of development allowed us to determine which types of farms were most effective during the post–accession period.

GROUPS – ON SELECTED EXAMPLES
Authors: Gonet Danuta
Published: August 2017

The article presents the issue of innovation in the members of two producer groups (X producers of geese and ducks
and Y producers of pigs) in relation to the farms. The source of the material was an interview questionnaire carried out
in 2015. The research used a descriptive and comparative method. Farmers of the characterized groups ran farms where
animal production was dominant, and therefore the innovations they implemented mostly involved animal production.
More than half of respondents in this department increased animal stock. The most important vehicle for innovation
for farmers was WODR training and courses. The innovations being introduced were mainly financed from own funds.
More than half of the farmers surveyed claimed that innovations influenced the modernization of their farms, which
had a positive impact on their economic performance and market competitiveness.

including occupational activity and related remuneration or living conditions. Satisfaction of life is
considered as the primary indicator of subjective quality of life assessment. The purpose of this paper was
to present the level and quality of women’s life with special attention paid to unemployed women in rural
areas, based on the example of the Siedlce district. Quality of life was assessed on the basis of subjective
factors. The main research tool was a questionnaire survey which enabled the information on the sociodemographic
characteristics of the respondents and the analysis of the question. The conducted research
found that the majority of the surveyed women from the rural areas of the Siedlce county assessed their
standard of living as average. A large group of women living in rural areas declared their intention to
emigrate to the city.

Authors: Klonowska-Matynia Maria
Published: August 2017

The aim of the paper was to determine the level of differentiation and classification of rural areas in the Zachodniopomorskie province in terms of human capital resources defined in the field of education. The linear ordering method in the study was applied, and as a result, each spatial unit the synthetic indicator was assigned, describing the total level of the resource. It was assumed the uneven spatial distribution of human capital. The obtained results confirm: a higher level of human capital cumulating on highly urbanized areas and the occurrence of deficits on peripheral areas characterized by qualitatively low educational competences (also outside the formal). The study encompasses rural areas defined as rural and rural-urban gminas distinguished according to the GUS administrative criterion. The Regional Examination Board (OKE) in Poznan, the National Census of 2011 (NSP), the Local Data Bank of the CSO and the data of Rural Development Monitoring stage 1 were the main data source.
