A recent issue of fine dust is particulate matter with a diameter of less than $10{\mu}g/m^3$. It's classified as a pollutant that has a fatal effect on the human body when inhaled. The fugitive dust must be well controlled, since the adverse effects of dust on the surroundings are increased when the dust is blown away by the wind. Since the construction site is the place where the most fugitive dust is discharged in Korea, managing the fugitive dust discharged from the construction site can be an important issue to solve the problem of domestic fine dust. However, since the construction industry in Korea is the largest in Korea, it is difficult to control the emission of fugitive dust in the domestic construction site. In this paper, we compare and analyze the fugitive dust regulations applied to construction sites in major cities and propose the improvement plans to help control the fugitive dust generated in domestic construction sites.

This article aims to analyze some conditions for the reinforcing social security rights of atypical construction workers, and their socio-economical effects, and furthermore, to explore political measures for compliance with obligation of the four basic social insurances. Although the construction industry is one of the pivotal industry sectors, which contributes to the economic development, it is a typical industry sector, half of whose manpower is atypical and irregular. This kind of reality results especially from its own sectoral features and employment structure. We will argue that our society needs political measures for compliance with obligation of the basic social insurances for the construction workers, and it would help the reinforcing social safety net of the precarious construction workers, and furthermore enhancing competition in the construction industry. For this purpose, we will suggest concrete conditions for compliance with obligation of the basic social insurances and prove its positive socio-economic effects. In the end, we will propose some detailed measures like direct construction, introduction of the prevailing wage, etc. for this politic approach.

Construction engineers are the core resource for the sustainable development of construction industry and positive images toward construction engineers give much impacts on recruit and retainment of the young and talented. Although previous studies reported on negative aspects of the image of construction industry, the image of construction engineers has not been properly investigated to date. The objective of the study is to compare images of construction engineers as perceived by general public and construction engineers themselves in order to identify key characteristics and implications. The result shows that construction engineers themselves, compared with general public, have more negative tendencies on images of construction engineers. The study suggests that it is critical to enhance the understanding of roles of construction engineers and their morality in order to improve general public's perception on construction engineers images. On the other hand, fundamental measures to be taken to restore the environments of construction industry for construction engineers to improve their self-perception on images of construction engineers.

Knowledge has been one of the key factors influencing the companies' competitive power. Domestic construction industries have introduced Knowledge Management from 1990s around major construction companies. However, construction organizations have recently give a skeptical response about Knowledge Management. The existing Knowledge Management in construction industries does not satisfy the demands of workers. Furthermore it makes workers do double business. Therefore, this study investigates the workers' satisfaction of Knowledge Management, and becomes the preliminary study to suggest how to improve Construction Knowledge Management.

Although Construction Failure Information has been reported in literatures, reports of research, and etc., it Is difficult to utilize the information because the information classification does not exist. Therefore, this study investigated and analyzed literatures of domestic and abroad research Institutions and suggested the Construction Failure Information Classification(CFIC). The CFIC is composed of four classified items; facility general information, failure situation information, failure cause Information, and failure counterplan information. Each item is divided sub-items. Through CFIC, Construction Failure Information can be standardized and utilized for useful data to prevent recurrences of construction failure.

3D printing technology is recognized as a core technology that will lead the next generation, and is a field that can have a large ripple effect if it innovates the existing construction production method. Therefore, this study deals with the development of a 3d printing system using an articulated robot for construction purposes. In this system, ABB robot was used to control the developed cement gun accurately. The system is composed of mixer to mix cementitious materials, pump to transfer the materials, abb robot to motion control and cement gun to extrude the materials to print required construction parts. Using the system developed in this study, a suitable mix ratio of cementitious materials was found and successively printed a 1m high structure that demonstrated possibility of printing structures using 3d printer. In the future, we plan to build a foundation for automated construction through research on construction methods and materials that can be continuously layered for the system.

The Construction New Excellent Technology was introduced to promote the development of domestic construction technology and enhance national competitiveness, by inspiring the development desire of technology developers in 1989. Domestic Construction New Excellent Technology is first introduced in 1989, the total 596 cases were assigned to the new technology and it was used the construction site. Also, it was achieved the quantitative performance of thirty-hundred applications and was effected to the domestic construction industry. However, the systematic analysis about the introduction effects of Construction New Excellent Technology are none. Therefore, the quantitative analysis of economic effects in construction industry have to a justification in according to operation of Construction New Excellent Technology system and verification of superiority. And then, the Construction New Excellent Technology system needs a developing base in the future. In this study, The Economic Impacts of Construction New Excellent Technology were analyzed in quantitatively such as a cost savings effects, the employment effects, the effects on Value-added, the import substitution effects due to use of Construction New Excellent Technology. This study will be used promotion of economics and superiority in the Construction New Excellent Technology.

In order to encourage construction practitioners to acknowledge failures and disseminate the information, the failure information must be documented and accumulated with a well-structured format, which contains not only the fact and result but also the circumstance and cause of the failure. In the Korean construction industry, many failures are not explained clearly and often not even reported publicly, partly because due to the lack of understanding positive aspects of failures, which can improve construction practices as a result of learning from failures. The purpose of this study is to develop a web-based construction failure information system using the case-based reasoning techniques, which can systematically accumulate, manage, and share the valuable failure information using a structured failure cases database. It can be utilized for planning proactive solutions on future failures by searching the very similar past failure cases.

After 1990s, the influence of construction industry has been decreased on national economy and construction business condition has been changed on economic recession and boom repeatedly. Larger fluctuation of business condition makes a forecast of it to be more difficult. Uncertainty in business prediction results in damages on construction companies and stakeholders. Therefore, study on forecasting a construction business is very important. This study suggests the Construction Industry Production Index(CIPI) to predict a construction business in consider of temperature effects. The results show that construction business is much influenced by temperature effects certainly and GDP. With the CBFM, this study examines CIPI for 2013 with two scenarios: 1)with GDP growth rate of 3.5% 2)with GDP growth rate of 2.4%. Thus, CIPI would be used as the economic state index to display the construction business conditions. Also, CIPI will be utilized as basic methodology in the impact of climate change in the construction industry.
