SummaryAn isonymic analysis has been carried out using a sample of 1529 reconstituted families residing during 1870–1964 in Aranjuez, an urban area situated south of Madrid, Spain. The random, non-random and total-components inbreeding coefficients from isonymy were obtained and the various combinations of surnames compared in order to infer the patri- or matrilocal pattern of residence. Throughout the period studied the random component of inbreeding (Fr) has not changed, in contrast to the non-random component (Fn), thus suggesting the latter could be responsible for the reduction of total inbreeding. Using several methodological approaches (biplot analysis, α, ν and percentage of immigrants) the predominance of the immigration of grooms was interpreted in terms of Aranjuez as a matrilocal pattern of residence. From this study it can also be concluded that surnames provided by reconstituted families are good estimators of inbreeding and migration.

Methodological Approaches

The concept of urban area is complex and has been discussed for many years by several authors and organisations through different perspectives and methodological approaches. For administrative and comparison purposes statistical institutions, both at the national and international levels, classify territories according to a certain degree of urbanisation defining typologies from which indicators and certain public policies are applied. The purpose of this study is to discuss the relevance and suitability of different urban typologies. Through mapping and measuring the data of official documents, the urban dimension of Mainland Portuguese territory is discussed and its usefulness concerning the allocation of resources for promoting territorial cohesion is stressed. Results show the inadequacy of these classifications to inform planning actions, decision making, and to promote territorial policies. It also provides evidence of inaccuracies that distort the reading of the territorial reality of the case study.

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.

San Cristóbal de Las Casas, ciudad media en Chiapas, ha tenido un rápido y desordenado crecimiento en las últimas décadas. Con el propósito de analizar la estructura del paisaje en un espacio periurbano de esta ciudad (el cerro Huitepec) y su relación con los procesos de apropiación social rural y urbana del territorio, se integró un análisis geográfico de los usos del suelo con un análisis social cualitativo por medio de entrevistas y cuestionarios. Se observa en este espacio periurbano un paisaje heterogéneo y diversificado donde los remanentes forestales son importantes, pero con variaciones al interior en función de las formas de uso y de los actores sociales presentes. Este paisaje cumple funciones relevantes para la conservación de los recursos naturales y la provisión de servicios ambientales en beneficio de la población local y urbana, pero su condición es muy incierta a futuro. AGRO-FOREST LANDSCAPES IN THE PERI-URBAN AREA OF A MEDIUM-SIZED CITY: AN OPPORTUNITY TO PRESERVE OR DETERIORATE FORESTS? In recent decades, San Cristóbal de Las Casas, a medium-sized city in Chiapas State, has shown rapid and chaotic growth. For studying the landscape structure in a peri-urban area of this city (Huitepec Hill) and its relationship with rural and urban social appropriation processes of the territory, a geographic analysis of land use was integrated into a qualitative social analysis through interviews and questionnaires. A heterogeneous and diversified landscape can be observed in this peri-urban area where the remaining forests are important, but show internal variations that depend on forms of use and the social stakeholders who are present. This landscape plays relevant roles in the conservation of natural resources and the provision of environmental services for the benefit of the local and urban population. However, its future condition is highly uncertain.

The author analyzes the problems of demographic development of industrial cities of the Angara area (Priangarye) in the 1990s. In particular, it focuses on the negative trends in the natural movement and migration of the urban population, which, in turn, led to depopulation. Distribution of municipal formations of the Irkutsk region in the total value of the mortality rate allows you to detect only the most general trends. The minimum level of total mortality was recorded in the south-eastern and central parts of the region, as well as in most large and medium cities. The highest values of total mortality rates were observed in the northern areas of the region and a number of rural and single-industry towns in central and eastern part of the region. Mostly, it's economically depressed municipalities with single-industry economy. According to the author, the causes of demographic instability in many industrial cities were laid during the Soviet period and were associated with the practice of attracting population and populating areas of new industrial development. The economic crisis and the aggravation of social problems in the 1990s seriously complicated demographic development of the urban population in the region. The demographic crisis of the 1990s could have been significantly smoothed over, if the federal and regional authorities had taken steps to stop the steady depopulation. In the context of the collapse of the political system demographic policy for many years had been pushed into the background. As a result, the demographic crisis, which takes root in the 1980s, fully manifested itself at the regional level in the first post-soviet decade.

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.
