The article outlines the directions of the ecological safety formation on the territory of IvanoFrankivsk urban system according to acoustic and electromagnetic load factors. In order to provide an acoustically comfortable environment for inhabitants of the urban system the authors solved the following tasks: measurements of the equivalent sound level along the highways and near the residential buildings close to the roads were made; special attention was paid to the public transport stops where the audio-boxes of the "Street Radio " are located. In general, an equivalent sound level Leqv was measured at 165 points within the territory of Ivano-Frankivsk urban system. According to the research results separate zones (streets) with the greatest acoustic discomfort within the city were allocated, profiles of acoustic load distribution along main streets were built, taking into account the equivalent sound level in the green zones of the city which are located nearby. Using the software program Surfer a noise map for the territory of Ivano-Frankivsk was built. To ensure a comfortable living environment within the urban system according to the factor of electromagnetic load the following tasks were solved: isotropic measurements of the electromagnetic field components at 122 points of the test-ground were carried out. At each point in terms of maximum and average values the following parameters were measured: electric field strength (E, V/m); magnetic field strength (H, mA/m); surface energy flux density (W, mkW/cm2). Base cellular network stations were recorded, their contribution to the electromagnetic situation of the city was described. The maps of technogenic electromagnetic pollution were built with the help of the program Surfer for the spatial analysis of changes in the electromagnetic field levels within the urban system. Spline interpolation method was used to build the maps. Moreover, measurements of 5 basic test objects of the urban system were carried out, which are the most vulnerable to the electromagnetic field influence. According to the research results the schematic images of the electromagnetic field distribution inside the objects were built. The most sensitive zones within the test objects were determined. Thus, according to the analysis of the conducted research favorable zones for comfortable and safe residence in Ivano-Frankivsk urban system according to the factors of noise and electromagnetic pollution were determined.

With the continuous expansion of urban scale, blindly increasing or controlling transportation infrastructure possibly creates a short board in an urban system. In this study, a macro traffic integrated system was constructed according to a city's economic size distribution and transportation infrastructure. The planning strategy of traffic, industry, space interaction and coordinated development was put forward. Through theoretical model, the evolution mechanism between transportation infrastructure and economic scale distribution was revealed. Starting from the center of the city and inter city level, China's new urbanization strategy was implemented, and a comprehensive transportation system model was built. The traffic planning in Singapore was taken as an example, and the solution to traffic problems such as congestion, traffic jam, and distance was obtained. Practice has proved that the rational and effective urban transportation infrastructure construction can effectively promote the coordinated development of economy and resources, and comprehensively enhance the level of integrated transport services.

Malaysia is a fast developing country which thrives on the growth of its population and economy. Kuala Lumpur is the capital of Malaysia with an area of 243 km2 has a population of 1.4 million [1]. From the statistics, the number of passengers using intercity train services in Malaysia in was 187,345,149 in the year 2012 [2]. Comfortability of a service is a major factor that influences the public. The research will be conducted at the City of Kuala Lumpur, PUTRA LRT (Kelana Jaya Line) and MONOREL Line is selected as the main focus of the research. The data collection will be conducted in the train coaches with two parameters. The noise and vibrations in the train coaches will be taken using the Sound Level Meter (NOR118) and Vibration Meter (Movipack 01dB-Steel) respectively. The noise data were obtained from the interior of the train coaches during operation, while the vibrations were obtained from the wall surface of the coach interior. The vibration aspect for this research is more focused on three parameters which are displacement (μm), vibration velocity (mm/s) and vibration frequency (Hz)[7]. Questionnaires were given out to the train passengers in order to obtain public opinions and satisfaction feedbacks relating their experiences on the train coaches. In this paper it also discusses on the outcomes of the field research work conducted and it was found that PUTRA LRT has a lower vibration value when compared to the MONOREL. The public opinion has also showed unanimous agreement to the field observations conducted by the researchers. However, MONOREL records lower noise levels compared to PUTRA LRT which means quieter journey experience to the commuters. It is hoped that this study will enable the operators to enhance their service weaknesses with the public playing a part in improving the urban rail transit in the City of Kuala Lumpur.

Abstract As a reaction to the complex global crisis, the notion of ecological urbanism has emerged in order to understand and attend the inaccuracy between the urban system and the environment of which it is a part. This article suggests that the form we perceive the city-nature relation deeply determines the praxis of urbanism arguing that the problem of ecological urbanism is essentially epistemological and ethical. Accordingly, the article introduces the concept of “landscape ecosophy” through which not only is possible to understand the indivisible connection of perception and socio-ecological practices, but also help us to reconnect the praxis of urbanism with a relational epistemology and landscape. The article empirically seeks to interpret how the Villarrica and Pucón urban system inhabitants in the Araucanía Region of Chile perceive and relate with the mountain and lacustrine landscapes in their daily practices of inhabitation. To achieve this, an ethnographic methodology is used. The discussion central line is represented by the question, ‘So close, but so far?’, as in spite of the fact that both cities are deeply connected to the landscape, their socio-cultural constructions are defined by the notions of disconnection and a lack of awareness. On the other hand, in a sort of circular causality, the article also identifies how certain urban initiatives may not only imply a reconnection between the urban system and the landscape of which it is a part, but also contribute to trigger the emergence of deeper landscape ecosophies.

The article is devoted to the interdependent identification of the city and park, which is carried out visualizing the opposition of their essential senses. In order to manage the traditional models of their consideration as separations, situationally constituent within the territorial union, the bases for examining the city as a space for the restoration of the human being and the need for its adequate, ontologically based, interdisciplinary studies, have been analysed. In this context, the park is considered as a visual legitimator of the city; the city is like the open dynamic structure that is in need of different, including indirect identificators. In such a way, a new – correlational – model of their study has been proposed, built on the visual ability to fix and covey the meanings. The visions of the city as the dominant territory of modern human implementation have real foundations resulting in the development of the relevant theoretical discourse, which is intended to find correct explanations. At this point, there is a connection of the city in its comprehensive value with the unified human being, which is the epicenter of the human matter realization – and in the processes of its permanent resurrection, and its own creativity as well. The force field of their attractive interaction foremost are man-made locations of the unutility nature, which represent the internal resource of decoding the humanistic symbolic signs. Absolute leaders in this essence are the parks designated in the city-building in the capacity of all recreational areas. In the visible picture of the city – its multivisuality – they have special words expressed by the way of visualization. Their use is optics directed to the depth of the human being. The park, built into the urban system, sharpens it as much as possible, facilitated by the controversy with the garden, in the visual text of which it fulfills a human saving function. Simultaneously, the park visions crystallize the semiosis of the city as a space of life-saving pragmatics.

The consequences of the floods that had affected the area of Serbia in 2014 indicated a very low level of preparedness of population to respond to natural disasters. Therefore, the aim of quantitative research is to examine the impact of fear on the willingness of citizens to respond to a natural disaster caused by the flood in the Republic of Serbia. Bearing in mind all local communities in Serbia where floods occurred or there is a high risk of flooding, there was selected a random sample consisting of 19 out of 150 municipalities and 23 towns and the city of Belgrade. In the selected communities, a research was undertaken in those areas that had been most affected in relation to the amount of water or potential risk of flooding. The survey used strategy of testing in households with the use of a multi- stage random sample. The research results indicate that the citizens who have a fear of floods are familiar with safety procedures to a greater extent in relation to citizens who do not have the fear; they have taken the preventive measures; they point out that they still are not ready to respond, but plan to do so in the next 6 months; they would evacuate to the upper floor of the house; they point out that someone in the family has educated them about the flood. In contrast to that, citizens who do not have the fear are not doing anything to prepare themselves to react in such situations, they are confident in their own abilities to cope with the consequences of floods, etc. The originality of the research lies in the fact that in Serbia there has never been conducted a research to examine the state of preparedness of citizens to respond. Bearing in mind that the research is based on the territory of Serbia, conclusions can be generalized to the entire population. The research results can be used when creating a strategy for improving the level of preparedness of citizens to respond.
