Due to the economic growth and improvement of the construction industry witnessed by most countries, there has become a crucial need for employing modern possibilities in the construction sector to build taller, longer and deeper structures. However, one aspect that heads forward with the same intensity is the generation of 100 million tons of construction waste every year. This generation has occurred due to several factors with different levels of importance. Hence, this study reveals 15 factors influencing construction waste generation and categorizes them into 3 groups, (materials management on site), (materials handling, transportation and storage) and (site management and practices). A questionnaire survey of 100 respondents was distributed among different engineers to assess the construction waste factors. Results showed that damage of materials on site, double handling of materials and incompetent contractor’s technical staff were the most significant factors of each category with Relative Importance Indexes (RII) of 0.866, 0.844 and 0.83, respectively. These findings will help the practitioners to reduce construction waste quantities in sites and improve waste management performance factors to control the construction waste problems.

Construction waste generation has been perceived as a crucial issue that has critical consequences on the project effectiveness and ecological effect of the construction industry. The key objective of the current research is to identify the root causes of material construction waste generation in Malaysia. A well-structured questionnaire was designed based on the 52 identified root causes of material waste generation. The developed questionnaire was distributed to 35 highly experienced in Malaysian construction industry experts. The collected data was analyzed by the use of mean score analysis. The top identified root causes are poor supervision during the construction stage, lack of efficient site management, last minute changes, cutting uneconomical sizes of materials, and constant design changes during the construction period. The initial findings will aid construction practitioners to focus on these root causes in order to reduce the material construction waste generation at construction sites.

Using Data

This study examines construction waste generation and management in Taiwan. We verify the factors probable affecting the output of construction wastes by using data for the output of declared construction wastes produced from demolition projects in Taiwan in the last year, expert interviews, and research achievements in the past, and find “ on-site separation” is the factor with effects on the output of construction wastes via cross-correlation by algorithms such as K-Means and Decision Tree C5.0. It can be seen that the output (0.092(t/M3) with on-site separation or 0.329(t/M3) without on-site separation is highly correlated with the composition ratio of construction wastes and referred to as a valid conclusion.

The process of producing new creative videos by editing, combining, and organizing pre-existing material (e.g., video shots) is a popular phenomenon in the current web scenario. Known asremixor video remix, the produced video may have new and different meanings with respect to the source material. Unfortunately, when managing audiovisual objects, the technological aspect can be a burden for many creative users. Motivated by the large success of the gaming market, we propose a novel game and an architecture to make the remix process a pleasant and stimulating gaming experience. MovieRemix allows people to act like a movie director, but instead of dealing with cast and cameras, the player has to create a remixed video starting from a given screenplay and from video shots retrieved from the provided catalog. MovieRemix is not a simple video editing tool nor is a simple game: it is a challenging environment that stimulates creativity. To temp to play the game, players can access different levels of screenplay (original, outline, derived) and can also challenge other players. Computational and storage issues are kept at the server side, whereas the client device just needs to have the capability of playing streaming videos.

Wooden Structures

Construction industry creates an environment for people's lives. On the other hand, construction activities have a negative impact on various aspects of the environment. It consumes natural raw materials, significantly contributes to carbon footprint, waste, etc. Appropriate choice of constructional, material, technical, technological and environmental parameters of buildings can partially reduce this negative impacts. By designing, implementing and using wood-based constructions it is possible to reduce the negative impact in the area of construction waste generation. Currently, the construction market offers a large number of construction systems of wooden buildings, which have both strengths and weaknesses. In this paper are identified construction systems of wooden buildings offered on the Slovak construction market. The aim of the paper is a detailed identification of construction waste generation during the realization of particular wooden structures and monitoring of waste generation in production factory (off site) and on construction site (on site) during the construction of wooden buildings. Based on the obtained information, the individual construction systems of wood-based constructions are compared in terms of construction waste generation

Positioning minority concerns within a power-sharing mechanism is a key issue that has been influential in Sri Lanka’s modern state-building process experimented from the later part of the colonial period. Throughout the post-independent era, most state-building projects were critically debated with regard to sharing political autonomy between the majority Sinhalese and the minorities. This study attempts to locate the claims and concerns of minorities seeking political autonomy in Sri Lanka’s state-building and power-sharing discourse. The study found that the state-building process in Sri Lanka has always been a struggle between establishing a majoritarian-ethno-nationalist hegemonic state system and preserving the right of minority ethnic groups to political power-sharing. The study further found that (a) insufficient emphasis given towards understanding power-sharing and federalism as a means to accommodate diverse interests and rights, including the political autonomy rights of minorities, (b) the opportunistic politics of opposition parties, and (c) the ethno-nationalist agenda of the majority Sinhalese were the major factors that have induced to undermine the minorities’ claims for political autonomy. The ultimate result of this is the continuous struggles by minorities to situate their political autonomy demands within Sri Lanka’s state-building and power-sharing discourse.
