Sustainable development as the leading civilization idea, and nanotechnology as the contemporary wave of technology significantly affecting the society, are brought together in this paper. A brief history of sustainability implementation from the start concept until European Construction Product Regulation is presented. The extended definitions of sustainable construction and sustainable material are analysed with adequate conclusions towards Concrete. The category of Exergy is implemented as a measure for “natural environmentally-friendly” meaning. The generalised concrete development curve is presented with discussion of Well Defined Concrete Performance. The statement that the sustainability is necessity for concrete and the nanotechnology is the chance for the future of concrete polymer composite is the final conclusion of the paper.

Old towns is like living fossil which has accumulated rich historical connotations; the one carrying the history of a region’ political, economic, cultural and ecological changes as well as the formative art created by collective labors and wisdoms of generations. The preservation of ancient Chinese dwellings and old towns began late; many historical architectures and traditional country fairs are forcibly removed during the transformation of old cities and towns, thus ancient towns with their original historical looks are becoming less and less. In comparison, the preservation and development of old western towns started earlier than china, with rich experience, they offer good examples for china, especially the successful developing way: eco-tourism. By comparing the preservation and development of traditional Chinese towns’ landscape features to that of western ones, this paper points out that the future development of old towns rely on proper handling of the relation between preserving and the feasibility of renewing, so as to maintain the landscape features of old towns in the course of sustainable development.

Construction activity is commonly considered to have adverse impacts on the environment, which is the basis of sustainable development for human being. Further, sustainability should be addressed mostly in developing countries, such as Sri Lanka, where a considerable amount of construction works is currently in progress and remain to emerge in the future. It is considered that the proper development and operation of a construction project can make significant contribution to the mission of sustainable development. However, the existing difficulty is the lack of the guidance for implementing sustainable development principles in construction industry. Therefore, this research intends to bring the necessity of mandated project feasibility studies as a guideline for sustainable development in the Sri Lankan Context. The research aim was approached through a qualitative survey strategy. To solicit the perceptions of experts on the identified sustainability performance criteria, a semi-structured interview survey was conducted. Ten experts were selected through purposive sampling strategy, who had experience in sustainable construction and project feasibility evaluation criteria. The manual content analysis method was used to analyse the collected data. Findings of the research revealed that though numerous sustainability assessment tools are being practised, there is a failure in sustainable construction in the current context. Thus, the minimum sustainability requirements were identified under the three pillars of sustainability, aiming to develop the project feasibility study as a guideline and to ensure sustainability performance from the project inception stage. These findings are helpful for industry practitioners especially the project owners to initiate a sustainable construction with concerted actions of all project stakeholders to safeguarding the future

Abstract The directions of development of the construction market are not only related to the need to own one’s own home but also to increasing functional and economic requirements and conditions of sustainable development. The perception and understanding of prefabrication in housing construction are undoubtedly starting to change. Sustainable construction criteria may constitute a significant turning point and support for the development of new prefabricated housing construction technologies. Entrepreneurs are slowly perceiving an opportunity for the development of prefabrication in the construction market. The implementation and popularisation of ready-made homes will undoubtedly constitute a favourable change in the Polish construction market; however, this will require a modification of habits. This article presents an historical analysis of the development of the prefabricated housing construction market as well as an attempt to answer questions concerning the future of prefabrication in housing construction in Poland based on the conducted studies.

The field of polymers in concrete is consolidated in the construction industry. The future of polymers in concrete is governed by the synergic interaction between these materials, in order to contribute significantly towards a more sustainable construction. Concrete-polymer composites (C-PC) have excellent mechanical and durability properties. Appropriate combination of polymers and classical construction materials provides opportunities for innovative applications and systems. This paper highlights the innovations and new approaches presented at the 13th International Congress on Polymers in Concrete in Madeira, Portugal, 2010 and at the 7th Asian Symposium on Polymers in Concrete in Istanbul, Turkey, 2012. The new trends presented are related with the micro and nanostructure, properties, test methods and applications of concrete-polymer composites.

David Magnusson has been the most articulate spokesperson for a holistic, systems approach to personality. This paper considers three concepts relevant to a dynamic systems approach to personality: dynamics, systems, and levels. Some of the history of a dynamic view is traced, leading to an emphasis on the need for stressing the interplay among goals. Concepts such as multidetermination, equipotentiality, and equifinality are shown to be important aspects of a systems approach. Finally, attention is drawn to the question of levels of description, analysis, and explanation in a theory of personality. The importance of the issue is emphasized in relation to recent advances in our understanding of biological processes. Integrating such advances into a theory of personality while avoiding the danger of reductionism is a challenge for the future.

Abstract. In this article, we reflect on 50 years of the journal Social Psychology. We interviewed colleagues who have witnessed the history of the journal. Based on these interviews, we identified three crucial periods in Social Psychology’s history, that are (a) the early development and further professionalization of the journal, (b) the reunification of East and West Germany, and (c) the internationalization of the journal and its transformation from the Zeitschrift für Sozialpsychologie to Social Psychology. We end our reflection with a discussion of changes that occurred during these periods and their implication for the future of our field.
