Soil dust emitted from large-scale construction sites in urban areas impacts air quality and creates a severe health threat to residents. Water spraying is commonly practiced to lower dust emission in construction sites, but its long-term effectiveness is questionable. In this study the utility of starch, polyvinyl alcohol (PVA), and a blend of starch and PVA in various proportions was investigated for the suppression of soil dust emissions at construction sites in Seoul. The efficiency of each dust suppressant was tested with test soil samples in a laboratory-scale wind tunnel box under different concentrations of suppressants and soil textures. Starch and PVA showed superior ability to suppress soil dust emissions compared to moistening bare soil, resulting in PM10 lower than the daily limit values of 30 μg/m3. PVA showed higher soil dust suppression capability for all conditions over starch. Test soils sprayed with dust suppressants significantly improved aggregate stability compared to untreated soils.

Technical risk assessment model of large-scale construction project has been established by using triangle whitening weight function of grey theory against the problems of technical risk assessment of large-scale construction project. In the end, through example verification, this model is approved to be feasible and have certain value of reference and utilization in similar problems.

The field monitoring of dangerous landslide is an important measure for guaranteeing its safety, especially when surrounded by large-scale construction. The landslide located nearby a reservoir in Shandong province. To guarantee construction safety, we adopted the automatic monitoring method for monitoring surface displacement and the internal soil pressure. The whole system uses solar power to provide energy and uses GPRS to transfer data. This system not only can provide reliable information for project construction, but also promote the application of environmentally friendly, low carbon in the monitoring field of civil engineering.

The tourism sector is one of the assets owned by each region in Indonesia. In Yogyakarta, there are agricultural or agro tourist established by PT. Bona Mitra Multifarm, Agrotourism is located at Jl. Jengger lempongsari Sleman Yogyakarta is used as an alternative tourism because no large-scale construction and do not damage the environment. Agrotourism is already running two years and has an area of 2 hectares with the main plant is dragon fruit, here there are three types of dragon fruit is r ed, yellow and white. Dragon fruit is chosen because it has economic value which is quite high when compared with other fruit, other than that the Dragon Fruit has enough health giving properties such as balancing blood sugar levels, purify the blood. Strategies in the management of agrotourism as a new alternative object in Sleman, such as maximizing the knowl e dge of management and communicating between all management and society. The need for the provision af the allocation of funds for the provision of facilities, provide conseling to peoples who don’t understand about agrotourism, seek operating funds from the central office for security improvements such as fencing garden. In supporting the advancement of society agrotourism around also has an important role as well as maintain the security and comfort of tourists that visit here, friendly, open food stalls, juice, puls counter, and angkringan outside agrotourism area. Except that, around of agrotourism any accommodating facility build by others industries, so that it should be aacility for tourist accommodation that visit to this agrotourism. Keywords: Alternative Tourism, Agrotourism, Dragon Fruit, Yogyakarta

The general purpose of this study is to investigate the effects of ISO 9001 certification on project success, and its main criteria into large-scale construction companies in Metro Manila, Philippines. For this aim, the research was conducted an in-depth literature review for identifying the main variables first. Subsequently, a survey questionnaire was designed, and distributed randomly among 67 managers working in ISO 9001:2008- certified projects of large-scale construction firms. Then the descriptive and inferential statistics analysis employed, in order to find the results and conclusions. Finally, the findings revealed that ISO 9001 certification can significatly affect the construction project success and its main criteria, except time lenght of projects in Metro Manila, Philippines.
