Problemas e catástrofes geradas por ações da natureza são cíclicos na história de nosso planeta.Um desses problemas, se não o principal e mais recorrente, são as inundações que vêm ocasionando diversos prejuízos tanto para a população quanto para os municípios em geral. Com o município de Itajubá-MG não é diferente. Principalmente por ter se desenvolvido às margens do rio Sapucaí, tem passado por problemas com inundações desde a sua fundação em 1819. No ano 2000, foi registrada uma das suas maiores inundações, que afetou 80% da sua população urbana. Atualmente, devido aos avanços da tecnologia, problemas referentes às inundações podem ser diagnosticados e evitados, utilizando-se programas computacionais, como Autocad e Global Mapper, com os quais, dentro deste trabalho, pôde-se se ter a real noção das áreas dentro do município em estudo susceptíveis a enchentes e inundações. Como principal resultado, observou-se uma mancha de inundação ocupando 65% da área urbana total do município, o que pode servir como base para realizar obras de prevenção e permitir um avanço municipal controlado. A partir desse levantamento pode-se ter a representação da fragilidade da cidade quanto a problemas ambientais decorrentes das chuvas torrenciais. Percebe-se a necessidade de um maior e melhor planejamento do crescimento urbano, por parte dos órgãos regulamentadores, adotando-se estratégias para o desenvolvimento eficiente e sustentável da região. Palavras-chave: Inundações. Planejamento. Problemas.   Flood spots in municipality of Itajubá-mg Abstract Problems and disasters generated by nature actions are cyclical in the history of our planet. One of these problems , maybe the major and most frequent, are the flooding which has been causing many losses for both the population and the municipalities in general. In the city of Itajubá -MG it is not different. Mainly because the city is located in the banks of the Sapucai river, it has experienced problems with flooding since its foundation in 1819. In 2000, the city faced one of its biggest floods, which affected 80% of its urban population. Currently, due to advances in technology, problems related to flooding can be diagnosed and prevented by using computer programs such as Autocad and Global Mapper, which ones, in this work, allow us to have a good idea about areas in the studied city, that could be potentially affected by floods. As the best result,  one flood spot occupying 65% of the urban area of the city was observed. The information can be used for preventing actions and as a base for a mediated growing. From this results, it is possible to measure how fragile is the city regarding to environmental problems related to storms, which requires that regulatory organizations make a bigger and better growing planning for the urban areas, applying strategies for the efficient and sustainable development in the region.

An urban area is the most important form of space-time interaction between society and nature. It is in the urbanized area that environmental problems are most acute. The developed Strategy of Ecological Safety of Russia for the period up to 2025 almost does not consider the role of geoenvironmental factors in the overall safety of the city. This article defines their place in the system of general ecological safety of urban areas. The structure of geoenvironmental hazards is introduced, and an example of their relationship is given. The algorithm of assessment is proposed and a version of the geoenvironmental safety system is developed for the urban area.

With the rapid expansion of the city in China, more and more old industrial buildings in cities become idle and abandoned. However, Old industrial buildings are carrying the history of a city and reflecting the urban development process so that renewal of the old industrial buildings has great value in the sense of cultural, aesthetic, ecological, economic, and sustainable development. How to reuse those buildings is worth studying. This paper, based on the principle of Adaptive Renewal and sustainable reuse, takes two typical successful cases to discuss how to reuse these old industrial buildings into culture ones in China.

This thesis discusses a method of analysing the input of interventions in a building's site design, all of which affect the heat island effect, bio-diversity and hydrology of urban areas. Existing standards from Toronto, Vancouver and Berlin have been researched and analysed. This paper presents an evolution of a method called biotope area factor used in Berlin, Germany. A synthesis of the approach of all three systems was considered and distilled into the key points which were then incorporated into the proposed method. In addition to the impact of an individual building, it also includes the impact from the adjacent street area. The final components of this thesis are the application of the method developed to an urban area in the city of Toronto and results showing the impacts on architectural design from site rating systems.

Abstract The uncontrolled expansion of urban areas is one of the main factors that reduce the liveability of cities. In recent years, to contrast urban sprawl, several nations have promoted policies aimed at developing urban green spaces. The importance of green oases within cities had already been highlighted, in 1977, by the architect Christopher Alexander who had developed a series of patterns including ‘City Country Fingers’ claiming that city development should consider the prolongation of country land in to the urban area. In several cities, especially in Japan, it is possible to recognize the imprint of urban development based on country fingers. This term refers to extensive urban intersections of agricultural land or wooded hills which, from the peripheral areas, penetrate the city. Inside them, there are urban windows, called city fingers, whose development direction is opposite to those of the country fingers. To recognize and analyze, in an automated way, these particular structures, a Python-based application was created. Starting from the original high-resolution image of Google Earth, a complete analysis was performed, labeling and delimiting urban and vegetational areas and extrapolating the main geometric parameters of the country and city fingers. The finalization of the results obtained was carried out through a classification model whose criteria were based on Alexander’s pattern. Thanks to this classification scheme, the distinction between Active Green Areas (country fingers) and Passive Green Areas (gardens and public parks) have been revealed for the analyzed cities. The tests performed showed almost ideal conditions for the city of Kamakura and a limited match for the urban area of Acireale. The proposed method is suitable for fields of application that require a qualitative and quantitative determination of the vegetation cover present within the city, an essential condition for correct territorial planning.

<p>Cooking operations can be an important fine PM source for urban areas. Cooking emissions are a source of pollution that has been often ignored and are not included or are seriously underestimated in urban emission inventories. However, several field studies in cities all over Europe suggest that cooking organic aerosol (COA) can be an important component of the total organic PM. In this study we propose and evaluate a methodology for the simulation of the COA concentration and its variability in space and time in an urban area. The city of Patras, the third biggest in Greece is used for this first application for a typical late summer period. The spatial distribution of COA emissions is based on the exact location of restaurants and grills, while the emissions on the meat consumption in Greece. We estimated COA emissions of 150 kg d<sup>-1</sup> that corresponds to 0.6 g d<sup>-1</sup> per person. The temporal distribution of COA was based on the known cooking times and the results of the past field studies in the area. Half of the daily COA is emitted during dinner time (21:00-0:00 LT), while approximately 25% during lunch time (13:00-16:00 LT). The COA is simulated using the Volatility Basis Set with a volatility distribution measured in the laboratory and is treated as semivolatile and reactive. The maximum average COA concentration during the simulation period is predicted to be 1.3 μg m<sup>-3</sup> in a mainly pedestrian area with a high density of restaurants. Peak hourly COA concentrations in this area exceed 10 μg m<sup>-3</sup> during several nights. The local production of secondary COA is predicted to be slow and it represents just a few percent of the total COA.</p><p> </p>

This article is devoted to the history of the higher primary school of Saints Sahak and Mesrop and its role in raising the intellectual level of the Nakhichevan population. The Crimean Armenian immigrants resettled on the Don land from the very beginning showed concern for the education of the younger generation. Since that time, the first educational institutions of the city-parochial schools have ceased to meet the educational needs of the urban population, as a result of which some parochial schools have evolved to a higher primary school, which can be clearly seen on the example of the School named after Saint Sahak and Mesrop. The article traces the difficulties and problems that the school's management had to face in the process of its development. The author examines the educational programs, as well as the teaching staff of the school. The successful functioning of the school was due to the invaluable assistance from both the entire Nakhichevan society and individual patrons in the education of the local Armenian population.

Introduction: The high prevalence of risk factors in women in developing countries of South Asia appears to have been translated into early and severe CHD in contrast to their counterpart in the first world nations, which has been related to obesity and insulin resistance and genetically determined increased lipoprotein Lp(a) levels. Mental stress due to urbanization, sedentary life style and physical inactivity may be the most important factor initiating obesity and the clustering of all other risk factors hypertension, dyslipidaemia and (WHR). These risk factors vary in different regions of South Asia. Aims and Objectives: Our aim of the study was to describe and analyse differences between the frequency of risk factors such as psychological stress due to, socio-economical aspects, life style especially physical activity, and health behaviours which may contribute in the course of CAD in women of both rural and urban areas of Pakistan because no such significant data is available in women with CAD. Study Design: This descriptive cross-sectional comparative study was conducted in Cardiology Department of Dow University of Health and Sciences Karachi, Pakistan, from March 2014 to March 2016 by filling a questionnaire and laboratory data. The study group comprised female subjects around 577 (Urban 347 {60.1%} and Rural 230 {39.9%}) women ranged from 25-65 years of age who underwent coronary angiography and had definite coronary atherosclerotic diseases. Our study was conducted by examining the psychological stress in women of both areas and its strength of association with frequency of other risk factors in female patients of urban and rural areas with definite CHD taking account the difference in age and education level into account. Result: Analysis of this study conducted at department of Cardiology in Dow University Karachi from March 2014 to March 2017 revealed that the women of rural area were comparatively more physically active then women of urban area. Prevalence of mental stress, hypertension, diabetes, obesity, higher BMI, hyperlipidaemia (especially TC) waist and hip circumference of both areas were found to be different after adjustment made for age. A considerable association was found between psychological stress and other factors in ischemic heart disease patients showing the p-value (p=0.043). Psychological stress was found 82% in both groups and (13%) women had no stress rated as normal more in rural (26%) vs (04%) in urban population. Physical inactivity in women with CHD was found in 92% urban in contrast to 45% in rural population, (p=0.009). Hypertension prevalence was more in urban 253 in comparison to 151 women in rural area. Diabetes Mellitus was also found more in urban than rural population, especially in age below 50, 79 (23%) urban vs 60 (26%) in rural population. Women beyond 50 years of age, 85 (24%) urban vs 64 (27%) rural area had prevalence of obesity comparatively higher in urban residents 71 (20%) than 44(%) in rural dwellers and 32 (9%) urban vs 16 (7%) in rural women in age range below 50 years. Higher waist circumstance was observed more in urban residents (4.8 cm) whereas BMI was more (1.8 unit) in women of rural area than urban women. Prevalence of smoking and nicotine chewing was relatively higher in urban population in below 50 years of age with 30 (09%) urban vs 13 (05%) in rural women and in age beyond 50, 11 (03%) urban vs 10 (04%) in rural women was witnessed. Average total cholesterol, serum triglycerides and LDL were found to be higher in urban compared to rural area residents and HDL was comparatively lower in urban area group. Mean cholesterol level was seen at average of 353 mg% in urban vs 223 mg% in rural population. Serum cortisol level showed significant variation in urban group 19.1 vs 14.2 in rural group (sample, as well as serum fibrinogen was raised more raised in urban population). Conclusion: Our study shows increased prevalence of mental stress and physical inactivity in female residents of urban area leading to Higher blood pressure, DM, dyslipidaemia and central obesity specially in Waist circumference than rural area. The mental stress induced by excessive demands of work at home and at working place with too little control is not unique to women of urban areas.

<p>Em decorrência de atividades antrópicas exploratórias, tem ocorrido aumento na supressão de espécies arbóreas, refletindo na biodiversidade e equilíbrio dos ecossistemas, reduzindo a população de espécies de abelhas.<strong> </strong>Objetivou-se com este trabalho, fazer um levantamento da ocorrência de árvores, nidificações e espécies de abelhas com intuito de incentivar o plantio de espécimes, principalmente nativos, na área urbana, para que ocorra uma maior proliferação das abelhas indígenas sem ferrão. Para tanto, realizou-se um estudo na Praça Dr. Joaquim Batista na cidade de Jaboticabal, SP. Através de consultas em literatura especializada, identificou-se o número de espécies arbóreas e abelhas sem ferrão, o número e altura média de nidificações, além da coleta de sementes para produção de mudas. Foram identificadas 27 espécies de árvores nativas, 14 exóticas, cinco de abelhas sem ferrão, 37 nidificações, com altura média geral de 2,3 m, além da produção de 20 mudas nativas. A elevada ocorrência de nidificações em plantas nativas e a presença de sementes, demonstram a adaptabilidade destes polinizadores, além de subsidiar a viabilidade da proposta de incentivar o plantio de espécimes, principalmente nativas em área urbana para a proliferação das abelhas indígenas sem ferrão. Estudos complementares podem ser realizados visando educação ambiental nestes locais.</p><p align="center"><strong>Encouraging the planting of native trees in the urban area for proliferation of stingless bees</strong></p><p>As a result of exploratory human activities, there has been an increase in the suppression of tree species, reflecting on biodiversity and ecosystem balance, reducing the population of bee species. The objective of this work, to survey the occurrence of trees, Nest establishment and bee species in order to encourage the planting of species, mostly native, in urban areas, so that there is a higher proliferation of indigenous stingless bees. Therefore, we carried out a study in Dr. Joaquim Batista Square in the city of Jaboticabal, SP. Through consultations in the literature, we identified the number of tree species and stingless bees, the average number and height of Nest establishment, besides the collection of seeds for seedlings. They identified 27 species of native trees, 14 exotic, five of stingless bees, 37 Nest establishment, with overall average height of 2.3 m, in addition to producing 20 native seedlings. The high occurrence of Nest establishment of native plants and the presence of seeds demonstrate the adaptability of these pollinators, in addition to supporting the viability of the proposal to encourage the planting of specimens, especially in urban areas native to the proliferation of indigenous stingless bees. Additional studies can be conducted to environmental education in these places.</p>

Taking into consideration that growth of urban population has impacts on land use and that managing urban population change is one of the most important contemporary challenges, this paper deals with the sustainable development of peri-urban zones which represent important an environment where employment opportunities are developed and resources exploited (particularly agricultural resources) and environment where important recreational and leisure activities could be pursued. Within the review of current concepts and planning practices, the concepts of multifunctional agriculture and multifunctional landscapes in peri-urban zones are pointed out, as well as EU Developing Periurban Projects. The paper particularly focuses on the current situation in Serbia, where there is no specific legal basis for the planning of peri-urban areas, although there are positive examples of strategies, regulations and planning documents which treat agriculture and greenery in peri-urban zones in a sustainable manner.

The spatial transformation of new urban areas into industrial urban areas impacts spatial structure, spatial patterns, and environmental degradation. This study aims to analyze the spatial transformation work as a determinant of the development of the new urban area of Metro Tanjung Bunga Makassar and analyze the relationship of spatial expansion, land use change and population increase for the growth of new city areas and the sustainable development of the Metro Tanjung Bunga area, Makassar city. The data for this study has been obtained through observation, surveys and documentation. The research approach used is a sequential explanation. According to the results, that excessive urbanization and maximum compaction led to spatial expansion towards the development of the new urban area of Metro Tanjung Bunga. Moreover, the increase in number has a dominant influence with a value of 32.3% on the growth of the new city area of Metro Tanjung Bunga, Makassar City. Spatial expansion, land use change, and population increase were determinants of growth factors in the new urban areas and they also had a significant impact on environmental quality degradation. This study recommends the importance of considering the impact of new urban spatial areas for the formulation of strategic policies on sustainable development as an effort to meet national development targets for the case of Metropolitan Cities in Indonesia.
