Working people spend around 54% of their waking hours at a workplace, according to recent statistics. Work-related stress is unavoidable, and it can damage the health of employees and affect business performance. In this paper, we argue that open space inside the workplace environment can have a positive influence on reducing overall stress levels in all the categories of users. To our knowledge, there is a significant lack of research considering specific business districts and the gated complexes called business parks, especially in post-socialist Eastern European cities, where there they are still a novelty. Empirical research in this study is on the single case study of Business Park “Airport city” in Belgrade, Serbia. Its main focus is on the survey conducted with 235 participants based on a questionnaire, which examines the relation between workplace stress and workplace environments. The findings from the questionnaire show that the frequency, duration, and activity of open space usage influence the stress levels of employees in this specific workplace, while it is not visible relating to their age and gender. Additionally, final implications suggest that improved open space, such as well-expected greenery, but also the urban design non-associative to workspace and the socialization and exercise amenities customized for frequent and short work breaks, can facilitate the overall well-being of employees. They are innovative elements in relatively underdeveloped research on stress measures with open space usage characteristics in the specific (gated) workplace setting.

This study addresses the influence of heat treatment and alumina coating on the corrosion of EN 1.4713 steel in 0.1 mol dm−3 sulfuric acid. The corrosion characteristics of three different samples are examined using the open circuit potential measurements, Tafel extrapolation, linear polarization resistance, weight‐loss method, and electrochemical impedance spectroscopy. The results showed that the application of the weight‐loss method yielded similar values to the electrochemical method in the first 24 h. A decrease in corrosion rate, in a similar manner, was observed for all three samples. The largest deacceleration was obtained for the alumina/titania‐coated sample. It was obtained that the heat treatment significantly increased the corrosion resistance, but only in the first 24 h. The alumina/titania coating decreases the corrosion rate by approximately 30 times at the beginning of the corrosion exposure and by nearly 300 times after 240 h. This coating could have a significant influence on construction design, which uses ferritic stainless steel as the material.
The purpose of this study is to reevaluate general theoretical and practical interpretation of vernacular architecture in Serbia in the 19th and the first half of 20th century. This incorporates the understanding of vernacular architecture in a wider context, through interpretations of various authors, who do not only observe its design value, but also the cultural and spiritual values. Since vernacular architecture cannot be recognized as a singular discipline, but within the area of many disciplines, the wider interpretation is mandatory. Although celebrated and recognized as archetypal, vernacular architecture in the studied period is fading away and gradually disappears, faced with modern building techniques and architectural styles, brought by formally educated builders. The goal of this study is to examine the processes within which mentioned transformation is occurring and, accordingly, to understand the vernacular architecture which developed in practice. Since vernacular architecture in Serbian historiography has up to now only been examined in the context of traditional rural architecture, or of, so called national style, the main premise of the study is to offer another approach to this kind of creation, so as to examine and critically view the recent dominant understanding of application of vernacular principles and elements in the architecture of the mentioned period.
This paper views proportion as a tool used by planners and architects to achieve a certain quality of space. Considering that proportion is used to observe the correlations between the whole and its parts, the paper examines the aspects of space from the spatial plan of a city to the architectural details. Also, despite the fact that proportion is the correlation of the dimensions of physical elements in space, the paper also perceives proportion through the correlation of the material and immaterial aspects of space. In this way, the focus is shifted onto the level of communication between the architectural - urban space and its users, that is, to orchestration through the perception and experience of space, rather than the outdated, proportional analysis of architectural form.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
