Recently, the expansion of social infrastructures and urban redevelopment, the construction works have been a rapidly increase. The subway's noise and vibration are on a continuously increasing status in its importance as by the industrial and cultural development process. Nevertheless, in our country, adequate alternative idea for the construction noise and vibration are not yet established. In this point, the purpose of this study is to know the vibration effect to the structure. This study was used to determine the standard of vibration and the way of losing vibration. The case of construction site is a good example. The data of this study was obtained by a construction company in Korea. Vibration effect could cause structural problems and affect human mental state. The results of this study are as follows; check the vibrating point, determine the suitable limit of vibration, make a good plan and construction.

This paper presents the results from a survey on root causes that led to fatal accidents in construction projects In Vietnam. The survey was conducted by means of structured questionnaires and interviews with relevant individuals such as Foremen, field engineers, and project managers working in construction companies located in Ho Chi Minh City, the largest city of Vietnam. The survey sample consists of in total 91 fatal accident cases that occurred in construction projects during the years 1996-2005 and were recorded in a report at the Vietnam Department of Labor-Invalids-Social Affairs. The current effort is aimed at determining the essential measures for avoiding fatal accidents that have been increasingly taking place in Vietnam construction firms. The findings from the survey provided a necessary basis for determination of critical factors to be used as safety indexes in developing a checklist for preventing fatal accidents in future construction project

The effectiveness of Building Information Modeling (BIM) tools and processes has been recognized by the industry and owners are beginning to adopt Triple Bottom Line accounting practices, to enhance economic performance and environmental and social performance. However, the widespread and practical application of Green BIM remains largely unrealized. The authors identify that lack of understanding of the applicability of sustainability metrics to BIM design process is a significant barrier to this adoption. Through literature review this paper outlines the various sustainability metrics available to construction and elaborates on the potential of BIM for sustainable design. The paper maps and correlates applicable concepts of sustainability evaluation systems to BIM and describes the constraints in current BIM tools.

Construction projects are full of risks. This is particularly the case in civil construction projects that are often featured with large scale, complexity and involving a large number of participating parties. The eventuation of risks typically results in extended project durations leading to an increase in the total project budget. The consequence can be amplified considering the significant impacts of civil construction projects on the society, from economical, environmental and social perspectives. This research investigates the significance of risks within civil construction projects and approaches to deal with risks. Semi-structured interviews were undertaken with local industry practitioners in South Australia on this matter. It is found that the industry is fairly aware of risks associated with civil construction projects and subsequently has procedures in place to attempt to minimize the impacts of these risks on the project outcomes. The interview results also indicate that there is limited utilization of software for the risk management purpose from the cost estimation perspective.

Sustainable development goals (SDGs) are designed to promote human and social development and address challenges related to sustainable economic development, in addition to creating quality employment. SDGs create new market and business opportunities that enable companies to effect business changes through innovative solutions. To tackle structural problems and create infrastructure for future societies, a national-level digital transformation strategy is being developed in Korea. The Korean government announced an investment plan for living social overhead capital (SOC) to address various social and structural problems caused by low economic growth. This study emphasizes the importance of building SOCs in accordance with the requirements of future societies. This study primarily aims to suggest business opportunities created by achieving SDGs, by analyzing business cases involving 3D printing-based construction. Implementing living SOCs through ingenious thinking will not only create new businesses and jobs through digital transformation, but also improve the economic and social value by encouraging community members to be proud of their future society.

The present paper was to explore the attitude of middle and high school students for Won-jo-kyo-je which, recently, has been a social issue. The present authors would like to, at first, suggest that it needs to be social consensus about Won-jo-kyo-je as a adolescent's prostitution in Korean society. Nowadays, Won-jo-kyo-je is socially issued and bring into legal problem. Thus, we tried to investigate the properties of Won-jo-kyo-je through analysing student's awareness about it and concluded that it is the same as prostitution.

Conflicts in public construction projects lead to increase social costs as well as construction costs and schedule delay. Therefore, it is important to evaluate the conflict in construction project and find appropriate solutions based on previous cases. In this research, the conflict factors and criteria for evaluating conflict are derived and 30 cases are evaluated by 11 conflict experts. Using k-means clustering, the cases are clustered by three clusters. The cases were analyzed according to the characteristics of each cluster and labeled as 'NIMBY and harmful facility conflict cluster', 'environmental and pollution conflict cluster', and 'PIMFY and small conflicts'. In the future, when conflict occurs in the public construction projects, the conflict can be evaluated using this clustering and the characteristics of the conflicts can be found. As a result, it will be helpful to mitigate the conflict quickly and effectively by looking for previous cases that are suitable for resolving the conflict through appropriate clusters.

This study investigated two science teachers' practical knowledge shaped during their science classes which intend to realize social construction of scientific models. The teachers' practical knowledge was qualitatively examined in terms of five content categories defined by Elbaz through the reflection-in-action based on video data of their teaching as well as the reflection-on-action based on their narratives and interview data obtained after their classes. The results shows: 1) two science teachers implemented their practical knowledge on appropriate subject matter knowledge when they provided students with scaffoldings to support building scientific models during the classes. 2) The teachers' knowledge about science curriculum played important roles to change the purposes of the classes from the transmission of difficult science concepts to the construction of scientific model appropriate to learning goals. 3) The teachers' implementation of pedagogical knowledge changed toward supporting students' group activities and model generations aligned to the intention of social construction of scientific models. 4) The teachers' practical knowledge about their 'selves' showed that a teacher's perception and implementation of his/her roles of helper, guide, or facilitator are important for students to construct scientific models through group activities. 5) The two teachers' practical knowledge the milieu of schooling is realized by their modes of interactions with student groups during their classes. Two teachers acted like a co-player with his students or like a coach to students near a playground. We discussed domain-specific characteristics about scientific model construction.

Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.

Today the social concern about Interior Design gradually requires wide comprehension. Also according to demanders' requirement. Universities cope with speed. Interior Design made by experts for the function and purpose in the conception of decoration. Therefore, Universities we responsible to educate for more capable professional designers. But management is the first concern for Interior Design Company students are going to work at. Interior Design has not the important state yet in Korea, it is hard to manage the company with design alone. As architecture must get admittion, design is apart from construction. but they are worked together in Interior Design. It is true that all the work of construction is Capenters' or technical engineers' work except space design. Of course students are interested in just design not in construction. Students majoring in design need wide understanding of construction not a concept design. but detailed design for construction and proper valuation ability to manage company. I propose component and practical use of nude construction department to understand detailed design.
