Today organizations are making considerable efforts in order to maintain excellent talent, and in particular, they are focusing on understanding their intentions of changing jobs which are most highly correlated with job turnover. In the case of architectural design firms, its intensity of work is very high unlike industrial settings, and it not only takes much time to cultivate new men of talent and but also is characteristic that employees can change livery easily because of the flexible labor market. The turnover rated by National Statistical Office indicates that specialized, scientific and technical service industry including the architectural design firm has a relatively high turnover rate compared to the average of the turnover rate of the overall industries. However, studies on intentions of changing jobs until now were conducted focused on employees engaged in other industrial areas, and it is true that studies regarding intentions of changing jobs of practitioners of architectural design firms are very insufficient. In this context, the present study aimed to draw determinants affecting intentions of changing jobs of practitioners of architectural design firms, to objectively understand the practitioners' intentions of changing jobs through importance analysis by each factor based on this and to make a comparative analysis of differences between the large scale architectural design firms and the small and medium sized architectural design firms.

The purpose of this study is to propose a new process model for architects and suppliers in AEC(Architectural, Engineering and Construction) industry, which comes from its utilization of a distributed database. Information used by participants of this process is not held in one singular application sewer, but in tile databases of multiple participants. This study addresses the problem of coping with dynamic information changes that architects face when designing with increasingly time-sensitive product information from multiple suppliers. It also describes the new distributed architecture for design representation, and outlines a corresponding process model to address the needs architectural designers during design and procurement phases. The feasibility of the process was tested in a prototype system that combines existing technologies, which allows for an objects transfer from the Web to the CAD application.

Recently, BIM has been widely applying in civil engineering projects centering on the private construction industry in order to establish self guidelines for spreading in practice. However, most BIM technologies and software are based on the architectural projects. In these environments, it is not easy to apply the BIM to a infrastructure field. Even BIM standards with IFC (Industry Foundation Classes) are also focusing on architectural projects. Especially, both private and public sectors do not know about how BIM delivery system should be performed, and how such deliverable should be submitted to the government yet. Thus, we need to analyze an application level of BIM S/W (Software) in real projects and verify their interoperability. Besides, since there are not any common standards that can exchange IFC models for civil engineering projects, we have many issues in converting as-built infrastructure models into IFC and delivering their design documents to the government. Accordingly, this study aims to perform a BIM process with commercial software for real road project after a detailed design process is finished and verify interoperability between diverse BIM software for securing BIM data reliability.

For multi-story structural systems, Korean steel industry has fostered development of a steel-concrete composite beam. Configuration of the composite beam is characterized by steel angle shear connectors welded to a U-shaped cold formed-steel beam. Effects of shear connector orientation and spacing were studied to evaluate current application of the angle shear connector design equation in AC495. For the study, interfacial shear resistance behavior was investigated by conducting 24 push-out tests and attuned using unreinforced push-out specimens. Interfacial shear to horizontal slip response was reported along with corresponding failure patterns. Pure shear connector strength was also evaluated by excluding concrete shear contribution, which was estimated in relation to steel beam-slab interface separation or interfacial crack width.

Recently orders of projects in the field of oil and gas plants have increased due to rising oil prices and consumption. The markets of oil and gas plants are expanding into the Middle East area and all over the world. Because the oil and gas markets have a lot of overseas construction operations, competition among advanced companies is more important. However, companies in the period of growth have not had enough competitive powers of license in the design phase. Therefore, they are faced with difficulty of adopting the technology which is maximizing the effect of investments, and scheduling of a long-range plan. In order to achieve adequate technology management and competitive power, this study considers a long-range plan through an analysis of an appropriate introduction and the strategic planning process of technology management.

This study has developed a design indicator required to promote green remodeling in school facilities. And, implemented the green remodeling pilot test on the school facilities that are planning actual remodeling. This pilot test suggested user participation design methodology such as verification of the developed design indicator, design goal setting, evaluation and adjustment of design proposal. The Green Remodeling Design Indicators were classified into 3 large categories of architectural performance, usability, and design through analysis of cases related to 'green buildings' and 'remodeling'. We have developed nine middle categories such as architectural and structural performance, facility performance, environmentally-friendly, circulation, space, amenity, harmony with surroundings, form and symbolization. In addition, 42 detailed indicators were developed for each category, including general, functional, and special indicators. For the verification of this study, two green remodeling design workshops were conducted for Gwangju J elementary school. The first design workshop presented the importance of the design indicator and set the goal of the design plan of green remodeling for project. And, the second Workshop presented the evaluation of the satisfaction with the design and the direction of future adjustment for project. The design indicator developed in this study can be utilized as a design indicator of design quality management and decision system for the school green remodeling in the future. In addition, by accumulating information on the Green Remodeling Project, it is necessary to spread green remodeling and construct a sustainable building environment.

The accelerating adoption of BIM (Building Information Modeling) is challenging collaboration practices established in the construction industry. The implementation of BIM involves changes in participants work, organization, processes and collaboration methods. Therefore there is a need to be able to measure effectively and accurately collaboration, in order to analyze and determine current practices and their performances in organizations (company, team project) as well as changes required. Previous researches scope from evaluating BIM maturity of an organization to BIM collaboration requirements but lack of proper tools and methods to analyze collaboration performances. This is especially true when it comes to evaluate the efficiency and collaboration performances of processes rather than systems or organizations. Thus this research aims to analyze systematically and comprehensively previous researches proposing diversified methods to evaluate BIM performances and collaboration. Furthermore it aims to suggest key indicators to evaluate collaboration performances of processes and project organizations. This research may contribute to better understanding of collaboration performances within organizations using BIM and further development of evaluation method for analyzing BIM design project.

Currently rebar spacing inspection is carried out by human inspectors who heavily rely on their individual experience, lacking a guarantee of objectivity and accuracy in the inspection process. In addition, if incorrectly placed rebars are identified, the inspector need to correct them. Recently, laser scanning and AR technologies have been widely used because of their merits of measurement accuracy and visualization. This study proposes a technology for rebar spacing inspection and fixing by combining laser scanning and AR technology. First, scan data acquisition of rebar layers is performed and the raw scan data is processed. Second, AR-based visualization and fixing are performed by comparing the design model with the model generated from the scan data. To verify the developed technique, performance comparison test is conducted by comparing with existing drawing-based method in terms of inspection time, error detection rate, cognitive load, and situational awareness ability. It is found from the result of the experiment that the AR-based rebar inspection and fixing technology is faster than the drawing-based method, but there was no significant difference between the two groups in error identification rate, cognitive load, and situational awareness ability. Based on the experimental results, the proposed AR-based rebar spacing inspection and fixing technology is expected to be highly useful throughout the construction industry.

Even though the Korean intoner architecture market has constantly developed in the past on the basis of the economic and social growth, it has had a tough time for varied reasons since 1998. Restructuring in the construction industry is required due largely to both the lack of market demand which resulted from the foreign exchange crisis and managerial trouble which is getting worse as time goes by. In actual, as the social necessity for remodeling in skyrocketing, the remodeling is getting more acclaim. That is because old architecture generates a great amount of architectural trash, and it is necessary to look for ways to saute the energy. In the wake of these situations, the remodeling industry is drawing attention as an alternative to the marketable limitations of the existing construction industry. However, it is true that the remodeling market has yet to be activated decisively. Accordingly, the purpose of this paper is to provide a basis for entering into and activating the remodeling market of the interior architecture industry by analyzing the scale and recent conditions of the remodeling sector.
