Abstract: Coastal development and marine ecosystems in Culebra Bay, Guanacaste, Costa Rica. Culebra Bay (North Pacific, Costa Rica) is under an accelerated process of coastal development since the implementation of the large-scale tourism development Gulf of Papagayo Project. This study aims to identify changes in the health status of marine ecosystems within the bay, during a 18yr time period (1993-2011). The high sanitary and aesthetic quality of this bay has remained constant through time. However, coral reefs are degraded and dead coral accounts for more than 65 % of benthic coverage, likely due to a combination of natural and anthropogenic factors. During the study period, only one of the developers consortium has proved their commitment to accomplishing the goals of sustainable development, as established in the bay’s Master Plan, through the practice of social and environmental programs. Management of natural resources in Culebra Bay requires the implementation of specific actions to promote the ecosystems’ recovery, with inclusion of all stakeholders. It must consider the current use of natural resources and include water waste management and environmental education programs. Rev. Biol. Trop. 66(Suppl. 1): S309-S327. Epub 2018 April 01.

AbstractThe database regarding the earliest occupation of Europe has increased significantly in quantity and quality of data points over the last two decades, mainly through the addition of new sites as a result of long-term systematic excavations and large-scale prospections of Early and early Middle Pleistocene exposures. The site distribution pattern suggests an ephemeral presence of hominins in the south of Europe from around one million years ago, with occasional short northward expansions along the western coastal areas when temperate conditions permitted. From around 600,000-700,000 years ago Acheulean artefacts appear in Europe and somewhat later hominin presence seems to pick up, with more sites and now some also present in colder climatic settings. It is again only later, around 350,000 years ago, that the first sites show up in more continental, central parts of Europe, east of the Rhine. A series of recent papers on the Early Pleistocene palaeontological site of Untermassfeld (Germany) makes claims that are of great interest for studies of earliest Europe and are at odds with the described pattern: the papers suggest that Untermassfeld has yielded stone tools and humanly modified faunal remains, evidence for a one million years old hominin presence in European continental mid-latitudes, and additional evidence that hominins were well-established in Europe already around that time period. Here we evaluate these claims and demonstrate that these studies are severely flawed in terms of data on provenance of the materials studied and in the interpretation of faunal remains and lithics as testifying to a hominin presence at the site. In actual fact any reference to the Untermassfeld site as an archaeological one is unwarranted. Furthermore, it is not the only European Early Pleistocene site where inferred evidence for hominin presence is problematic. The strength of the spatiotemporal patterns of hominin presence and absence depend on the quality of the data points we work with, and data base maintenance, including critical evaluation of new sites, is crucial to advance our knowledge of the expansions and contractions of hominin ranges during the Pleistocene.

Seven different species viz. Chanda baculis, Chanda ranga, Amblypharyngodon mola, Oxygaster bacaila, Clupisoma atherinoides, Corica soborna, Mystus vittatus and a group of mixed SIS fishes viz. Mastacembelus pancalus, Xenntodon cancila, Chanda baculis and Glossogobius giuris were used for preparation of dust which can be preserved for a time period. The fishes were sun dried or oven dried, which are also method of preservation. Quality of the oven-dried fish was better than that of the sun-dried fish, but sun-drying process is easy and can be used in large scale. The fish powder remained in good condition for 7-9 months at normal room temperature, but at -18°C the powder was in good condition throughout the year. Highest quantity of powder from 1 kg of fish was obtained in case of the mixed species as 24.61% and the lowest in O. bacaila which was 20.52%. Biochemical analysis showed that the maximum calcium content was found as 1.34% in M. vittatus and minimum was 0.80% in mixed SIS fishes. Maximum phosphorus content was 2.90% in C. ranga and minimum was 1.72% in C. soborna. Maximum iron content was found as 45.20 mg/100g in mixed SIS fishes and minimum was found as 16.85 mg/100g in O. bacaila. The maximum moisture content was found in C. ranga (13.50%) and the minimum in mixed SIS fishes (11.65%). The maximum protein content was recorded in the mixed SIS fishes (72.45%) and the minimum in C. ranga (52.65%). The experiment was replicated three times and conducted from July 2005 to July 2008.

Research has shown that spending too much time indoors and disengagement from outdoor environmental stimuli may have detrimental health effects. These negative effects are even more serious in hospitals, where patients are highly stressed and have to spend most of their time indoors. Studies show that, in these situations, patients prefer to have a window with a desirable view. Although the desire for having a room with a view among hospital patients is well established, not all views are equally desirable. The parameters which make a view “desirable” are not well understood. This paper presents results of a large-scale human factors research study using patients’ qualitative assessments on thousands of “view” photos ( n = 2000), in order to provide a reliable foundation for developing a robust rating system to accurately quantify the desirability quality of views in healthcare settings. The results show that “distant” and “nature-dominant” views were, by far, the most desirable. Additionally, the results showed that while “water features” was also viewed desirable, views of moving cars and industrial settings were viewed most negatively. Moreover, the study revealed that natural views are not “always” more pleasant than urban views, and the positive reaction is mostly the result of aesthetic quality of the view content. Practical application: This study provides empirical confirmation that validates previous studies regarding the association of view content and building occupants’ preference, specifically within healthcare settings. It also provides a reliable foundation for developing a robust rating system to accurately classify and quantify the quality of views in healthcare settings. Furthermore, the findings of this study can be used by designers to better incorporate the needs of healthcare design community and those who aim to consider view in the design stages of new built spaces or retrofit of existing spaces.

AbstractStatistical downscaling models (SDMs) and bias correction (BC) methods are commonly used to provide regional or debiased climate projections. However, most SDMs are utilized in a “perfect prognosis” context, meaning that they are calibrated on reanalysis predictors before being applied to GCM simulations. If the latter are biased, SDMs might suffer from discrepancies with observations and therefore provide unrealistic projections. It is then necessary to study the influence of applying bias correcting to large-scale predictors for SDMs, since it can have impacts on the local-scale simulations: such an investigation for daily temperature and precipitation is the goal of this study. Hence, four temperature and three precipitation SDMs are calibrated over a historical period. First, the SDMs are forced by historical predictors from two GCMs, corrected or not corrected. The two types of simulations are compared with reanalysis-driven SDM outputs to characterize the quality of the simulations. Second, changes in basic statistical properties of the raw GCM projections and those of the SDM simulations—driven by bias-corrected or raw predictors from GCM future projections—are compared. Third, the stationarity of the SDM changes brought by the BC of the predictors is investigated. Changes are computed over a historical (1976–2005) and future (2071–2100) time period and compared to assess the nonstationarity. Overall, BC can have impacts on the SDM simulations, although its influence varies from one SDM to another and from one GCM to another, with different spatial structures, and depends on the considered statistical properties. Nevertheless, corrected predictors generally improve the historical projections and can impact future evolutions with potentially strong nonstationary behaviors.

Abstract Everyone in Indonesia has the right to a good and healthy environment as a form of human rights. Every generation has obligations and responsibilities in preserving the background to ensure the welfare and quality of life between ages. Sustainable development is an effort to guarantee these rights by managing natural resources wisely and rationally and simultaneously considering economic, social, and environmental aspects. Currently, humans tend to be greedy for existing natural resources to get the maximum benefit. Illegal logging is an activity to place forest resources on a large scale without paying attention to the needs of future generations. Efforts made by the government to enforce sanctions against perpetrators of illegal logging activities are the enactment of Law Number 32 of 2009 concerning Environmental Protection and Management and Law Number 18 of 2013 concerning Prevention and Eradication of Forest Destruction.

In the article fundamental directions of mountain tourism development in central part of Croatia and western part of Bosnia and Herzegovina are considered. Favorable natural conditions and transport accessibility contribute to the development of tourism. From other side, the consequences of the war 1991–1995s are still being felt. Contradictions between the goals of mass recreation and the objectives of environmental protection slightly aggravated due to the organization of specially protected natural areas where the rules of visiting are brought to perfection. There are great opportunities for the development of tourist infrastructure. To ensure that the recreational load on natural objects is not excessive it is necessary to regulate tourist flows and advertise new types of tourism. Recreational development of natural resources is part of the overall problem of their rational economic use and protection. Economic activities have different impacts on natural recreational resources. In this region under economic circumstances, it is more profitable to organize a vacation than to undertake the exploitation of natural resources in industry and agriculture. Another advantage is the lack of raw materials bases and closure of small industrial enterprises, this made it possible to organize open-air museums. From other side, agrotourism has been widely developed, it is a sign of the agricultural development of the territories. The features of different tourism types (water, walking and large-scale, mountaineering, sports and walking, speleological) are reviewed. Tourists should to spent the rest at winter and at summer in definite areas. A lot of natural and anthropogenic factors were taken into account under assessing recreational potential. Mapping produce in ArcMap 10, also for processing of Earth remote sensing data ERDAS Imagine program are used. Nature protection areas and principal rules regulating visits them was described.

AbstractA review of morphological and morphodynamic studies of the coast of the Kaliningrad oblast has been carried out for half a century. The studies include monitoring measurements by the Atlantic Branch of the Shirshov Institute of Oceanology of the Russian Academy of Sciences (AB IO RAS) with the participation of the state institute Baltberegozashchita (BBZ), as well as pre-war studies and cartographic analyses of long-term coastline migration carried out by the private company Baltic Aerogeodetic Enterprise (BaltAGE). It shows the spatial alternation of abrasive and accumulative areas, as well as frequent changes in beach width and height within the same morphological coast type. A change in the development trend of particular coast sections from year to year was noted. The significant influence of anthropogenic factors on the coastal development was emphasized, including changes in the direction of coastal retreat/advance along an extensive coastal stretch. Comparison of the interannual and nearly century-old dynamics of the coast revealed noticeable differences between them, with opposite trends in several large-scale coast sections.

Agnese Kusmane's (Mg.art.) Doctoral thesis “The Role of the Visual Aesthetic Quality of Public Space in Appropriation Processes of Large-Scale Residential Areas” is based on the topicality of the theme: residents' dissatisfaction with the quality of public space in large-scale residential areas being one of the most important aspects of topicality. The aim of the work is to evaluate the impact of the visual aesthetic quality of public space on the intensity of its appropriation in large-scale residential areas and provide landscape and building architects with the methodological framework for the reconstruction of public spaces in these areas. In order to achieve the aim of the thesis, the following tasks have been carried out: environmental psychology findings on aesthetic quality evaluation connecting metric values, configurational components and space-forming elements have been compiled, creating Matrix of Visual Aesthetic Quality of Space; brief overviews of the history and current state of large-scale residential areas in Riga and Berlin has been provided; a semi-structured interview method has been developed and applied for the study of spatial quality assessment of residents in three large-scale residential areas of Riga, amending the Matrix with data obtained through the semi-structured interviews; the relation between the intensity of public space appropriation and the landscape design and spatial organization in Berlin residential areas has been studied with the observation methods, controlling and refining the Matrix of Visual Aesthetic Quality of Space; a method for measuring spatial quality based on the Matrix has been developed. Several methods have been used in the work, including the monographic, semi-structured interview, deduction, participatory observation. There are four chapters in the work. The first chapter analyses the literature dedicated to the research of spatial quality, its impact on the intensity of outdoor appropriation. Based on the findings of environmental psychology, a category-based initial version of the Matrix of Visual Aesthetic Quality of Space is developed. The Matrix correlates the assessment of the visual aesthetic quality of the public space and the expected intensity of appropriation. The first chapter concludes with the development of methodological steps aimed at improving and refining the Matrix. The second chapter examines large-scale residential areas of Riga and Berlin from a historical and contemporary perspective. The demographic characteristics of the population are also considered. In the second chapter, it is concluded that residential areas of Riga and Berlin are compatible for studying the impact of public visual aesthetic quality on the intensity of its appropriation, and the data can be converted into the Matrix. In the third chapter, the assessment of public space quality is performed through the initial version of the Matrix, finding out which spatial categories are represented in large-scale residential areas in Riga and Berlin. Further, semi-structured interviews are conducted in residential areas of Riga on the relation between the aesthetic quality of public space and the expected intensity of appropriation, the interview data are included in the Matrix, improving it. At the end of the chapter, observations are carried out focused on relation between the visual aesthetic quality of public space and the intensity of appropriation in Berlin; the obtained data is integrated into the Matrix of Visual Aesthetic Quality of Space, specifying it. The fourth chapter discusses the findings of the work on the relationship between the assessment of the visual aesthetic quality of the public space and the intensity of its appropriation. At the beginning of the chapter, the relation between the metric values, configurational components and space-forming elements of different spatial categories included in the Matrix and the intensity of outdoor appropriation is analysed in detail. Further, the chapter discusses the role of the blue-green structure in the context of public space appropriation forecasting. The fourth chapter concludes with methodological recommendations for the application of the Matrix of Visual esthetic Quality of Space. The paper concludes that the intensity of outdoor appropriation can be most accurately predicted in outdoor areas dominated by blue-green structure. The thesis consists of 172 pages. The thesis includes 30 tables, 80 figures, 3 appendices and 372 sources.

Cerebrovascular diseases are a problem of the world today, and according to the forecast, the problem of the near future arises. The main risk factors for the development of ischemic disorders of the cerebral circulation include oblique and aging, arterial hypertension, smoking, diabetes mellitus and heart disease. An effective strategy for the prevention of cerebrovascular events is based on the implementation of large-scale risk control measures, including the use of antiagregant and anticoagulant therapy, invasive interventions such as atheromectomy, angioplasty and stenting. In this connection, the efforts of neurologists, cardiologists, angiosurgery, endocrinologists and other specialists are the basis for achieving an acceptable clinical outcome. A review of the SF-36 method for assessing the quality of life in patients with the effects of transient ischemic stroke is presented. The assessment of quality of life is recognized in world medical practice and research, an indicator that is also used to assess the quality of the health system and in general sociological research.

Since its evolution environment has remained both a matter of awe and concern to man. The frontier attitude of the industrialized society towards nature has not only endangered the survival of all other life forms but also threatened the very existence of human life. The realization of such potential danger has necessitated the dissemination of knowledge and skill vis-a-vis environment protection at all stages of learning. Therefore, learners of all stages of learning need to be sensitized with a missionary zeal. This may ensure transformation of students into committed citizens for averting global environment crisis. The advancement of science and technology made the life more and more relaxed and man also became more and more ambitious. With such development, human dependence on environment increased. He consumed more resources and the effect of his activities on the environment became more and more detectable. Environment covers all the things present around the living beings and above the land, on the surface of the earth and under the earth. Environment indicates, in total, all of peripheral forces, pressures and circumstances, which affect the life, nature, behaviour, growth, development and maturation of living beings. Irrational exploitation (not utilization) of natural resources for our greed (not need) has endangered our survival, and incurred incalculable harm. Environmental Education is a science, a well-thought, permanent, lasting and integrated process of equipping learning experiences for getting awareness, knowledge, understanding, skills, values, technical expertise and involvement of learners with desirable attitudinal changes about their relationship with their natural and biophysical environment. Environmental Education is an organized effort to educate the masses about environment, its functions, need, importance, and especially how human beings can manage their behaviour in order to live in a sustainable manner.  The term 'environmental awareness' refers to creating general awareness of environmental issues, their causes by bringing about changes in perception, attitude, values and necessary skills to solve environment related problems. Moreover, it is the first step leading to the formation of responsible environmental behaviour (Stern, 2000). With the ever increasing development by modern man, large scale degradation of natural resources have been occurred, the public has to be educated about the fact that if we are degrading our environment we are actually harming ourselves. To encourage meaningful public participation and environment, it is necessary to create awareness about environment pollution and related adverse effects. This is the crucial time that environmental awareness and environmental sensitivity should be cultivated among the masses particularly among youths. For the awareness of society it is essential to work at a gross root level. So the whole society can work to save the environment.
