The purpose of this study is to propose a simplified environmental impact assessment method based on selection of major building materials for school buildings in Korea. To accomplish this, environmental impact of 2 school buildings constructed in Korea was assessed according to the procedure of life cycle assessment. In addition, major building materials of school buildings were selected from the perspective of 6 environmental impact categories based on the assessment result, and a method of simplified environmental impact assessment was suggested. On one hand, case analysis verified applicability of the simplified environmental impact assessment method proposed in this study by showing similar value within 10% compared to the assessment result from existing detailed assessment.

Characterized by excessive moisture at the base of a wall that slowly diminishes in the ascending direction of the wall, rising damp may contaminate building materials with hygroscopic salts. The selection of treatment methods for rising damp should be supported by an exhaustive evaluation and study of the conditioning factors to achieve a successful outcome of the treatment. Many intervention techniques exist for situations that present rising damp, varying in approach and application methods.Due to the information about treatment products and systems for rising damp being generally dispersed, this may cause the selection of treatments with inadequate approaches that hinder the effectiveness. Thus, a necessity exists to collect and systematize information on all treatment options for rising damp. HUMITECNIC files/catalogue allows the fulfilment of that objective.HUMITECNIC files/catalogue is prepared based on an extensive search of systems, products and treatments in the civil engineering marketplace, patented or not, accompanied when necessary by a suitable bibliography. In this way, the user is presented with different treatment options that communicate the intervention approach, the technology used, installation process, relevant properties, application and limitations. In a way to promote the information to users in a dynamic an interactive way, the catalogue is available from the purpose built HUMITECNIC website.

Ants build complex nest structures by reacting to simple, local stimuli. While underground nests result from the space generated by digging, some leaf- and grass-cutting ants also construct conspicuous aboveground turrets around nest openings. We investigated whether the selection of specific building materials occurs during turret construction in Acromyrmex fracticornis grass-cutting ants, and asked whether single building decisions at the beginning can modify the final turret architecture. To quantify workers' material selection, the original nest turret was removed and a choice between two artificial building materials, thin and thick sticks, was offered for rebuilding. Workers preferred thick sticks at the very beginning of turret construction, showed varying preferences thereafter, and changed to prefer thin sticks for the upper, final part of the turret, indicating that they selected different building materials over time to create a stable structure. The impact of a single building choice on turret architecture was evaluated by placing artificial beams that divided a colony's nest entrance at the beginning of turret rebuilding. Splitting the nest entrance led to the self-organized construction of turrets with branched galleries ending in multiple openings, showing that the spatial location of a single building material can strongly influence turret morphology.

Land Readjustment

Purpose – The rapid urban population growth in Ethiopia is causing an increasing demand for urban land, which primarily tends to be supplied by expropriation of peri-urban land. The process of urban development in Ethiopia is largely criticized for forced displacement and disruption of the peri-urban local community. Thus, the purpose of this paper is to introduce how Ethiopia’s urban development system could be built on the participatory and inclusive approaches of land acquisition. Design/methodology/approach – The study has employed questionnaire survey results, focus group discussion with panel of experts and previous research reports to examine the peri-urban situations and then to show why an alternative land development approach is needed to be introduced in the urban land development system of Ethiopia. Desk review on land readjustment was also made to explore best lessons from other countries applicable to the peri-urban contexts of Ethiopia. Findings – This study has explored that land readjustment is potentially an appropriate land development tool to alleviate peri-urban land development limitations in Ethiopia. Practical implications – Researchers, policy makers and government bodies that are interested in peri-urban land would appreciate and consider implementing the adapted land readjustment model as an alternative land development tool. Consequently, the local peri-urban landholders’ rights would be protected and maintained in the process of urbanization. Originality/value – Although land readjustment has the potential to achieve participatory peri-urban land development, awareness of the method in the Ethiopian urban land development system is inadequate. This study contributes to fill this gap and create an insight into the basic conditions for the adaption of the tool.
