After the 2008 global financial crisis, the construction environment in South Korea continued change in the construction environment. Construction orders in 2011 have shown a downward trend compared with the previous year. Along with these changes in the construction market, the professional capabilities of construction project managers that are perceived as important also changed after the global financial crisis. Accordingly, this study was conducted to identify the major business capabilities of the current construction project managers and to determine which of these capabilities have undergone changes in terms of the importance accorded to them after the global financial crisis, and ultimately, to derive the construction project manager capability areas that need to be strengthened according to the changes in the construction environment. The capabilities of construction project managers were surveyed at two different time points: in 2007 and in 2010. The results show that the year 2010, after the global financial crisis, an increase in the perceived important capabilities of construction project managers compared with 2007. This results the impact of the changes in the construction environment on the importance of construction project managers. This study derived the ramifications of the early identification of systems and prospects according to the changes in the construction circumstances on more efficient onsite and human resources management, by considering the appropriate capabilities of the construction project managers.

Among various methods to build the construction safety, the consecutive improvement by the measuring and evaluating safety management capabilities for the construction participants such as an owner, a contractor, and a supervisor (construction project manager) can be the effective one. Thus, an effective evaluation and grading criteria to provide performance index for the implementation of safety management activities should be necessary. In this regards, the purpose of this study is to verify the adequacy by offering a competency evaluation system for the supervisor's safety capability and by applying the system to some construction sites. The proposed evaluation system was developed on the basis of the principles of safety management & accident prevention, basic elements of safety and health management system, and safety evaluation cases at home and abroad. The trial evaluation showed that the safety management of the construction site is mainly carried out by the contractor and the supervisor's awareness for the safety management is low on the whole. Especially, it is urgent to improve the support system from the supervisor headquarter and to place the dedicated safety management person in the field.

Purpose - The labor management department is an important area in charge of the labor-management relations that affects the competitiveness of the company. This study seeks to diagnose labor management education focusing on labor manager competency strengthening curriculum that is currently being conducted domestically and propose an educational model that can contribute to the labor manager competency development by researching improvement measures. Research design, data, and methodology - In this study, the first phase is a Delphi open form survey and 15 expert panels participated. The second phase had 31 expert panels participating and in the final IPA analysis, targeting 111 on-site subjects, it conducted a survey regarding desired level of current educational level and future education requirement. Results - A final 57 subjects regarding 11 items to increase the competency of the labor managers through the first and second Delphi survey was deduced through this study. To add, regarding the current education level and desired level that the current workers are thinking with respect to analysis results of the 57 subjects through the IPA analysis, an educational model could be deduced to increase competency of the labor managers based on the result. Conclusions - Thus far, research regarding labor management has been insufficient as it was defined as a subordinate role to human resources. This study reviews the role and competency of labor managers and presented an educational model to strengthen the capabilities of internal labor managers to re-illuminate the labor manager. However, this study is limited in terms of the diversity of the types of companies participating and the small number of panels. Better data can be produced if such parts are supplemented in the future.

Integrated heterogeneous database systems provide the unified interface for users and applications today in order to access the underlying diverse data sources located in different sites. The multiple heterogeneous data sources have the different and specialized data structures and transaction processing capabilities. Because of local autonomy, the local system does not have the capability of cooperation to control the global transaction. Hence designing the global transaction manager with supporting the global serializability is difficult task. To resolve the well-known indirect conflict, we define the global transaction model by using the characteristics of global integrity constraints. And then we propose the site-locking operation and its protocol to manage the global transaction. The correctness and analysis of our site-locking protocol is proved and performance gain over the related other methods is also estimated in this paper.

As the Construction Technology Promotion Act was revised in 2015, the term of Supervision was removed and Construction Management was included instead. The consideration of Construction Management shall be based on the cost plus fee method specified in the Criteria for the Cost of Construction Technology Services of the Ministry of Land, Infrastructure and Transport. Nevertheless, it is based on the construction cost ratio in accordance with the Economy and Finance Ministry's Detailed Guidelines for Preparing the 2018 Budget Plan and Fund Management Plan (Manual for Business Type and Item). As a result, it has been expected that Construction Management consideration will be calculated according to a single government standard and that the Criteria will be applied reasonably. In addition, although the change in the Labor Standard Act has a significant effect on the working environment of the construction site, the nature of the construction site is not considered in this Act. Based on these problems, the study suggested that the government should apply a single standard after consultation with the relevant agencies when calculating the consideration for Construction management, that the scope of the Criteria for the Cost of Construction Technology Services should be clear, that the amount of input by the Construction Manager should be considered for the capability of engineers and the number of working days, and that construction characteristics should be considered when determining the number of working days and hours.
