It is not easy to present a generalized operating model because the operating environment of a sport event is composed of a complex matrix structure. In this study, we propose 'standardization' which provides guidance of concept and process of sport event management to solve this sports event management problem. To purpose complete of this study, the frame was developed by the international standard ISO 9001: 2015 is applied. The standards framework for sports event process management system structure proposed in this study consists of scope of application, citing standard, Terms and definitions, organizational situation, leadership, planning, support, operation, performance evaluation, and improvement. This sport event process management system standard can be applied to any organization that wants to host, prepare, and operate sport events regardless of the form or scale of the sport event. In addition, this standard was focused on process management of life-cycle stages of sporting events, therefor it was possible to manage interrelationships and dependencies between processes and processes.

As the utilization of the BIM model increases in the design and construction stages of a construction project, the utilization of BIM in the maintenance stage can also increase. In the maintenance stage, BIM objects created in the design and construction stages that have already been completed are used. Therefore, it is necessary to verify the reliability of whether the used BIM object is a certified model created in the design stage. In particular, the reliability of the BIM model becomes more important in a project such as railway facilities composed of various construction activities with civil engineering, architecture, electricity, signal, and track work. This study proposes a methodology of using blockchain technology as a way to secure the reliability of the BIM model used in the maintenance phase, and constructs the block structure and detailed process for applying the blockchain technology to BIM. In addition, by applying this process to the BIM model of an actual facility to generate a block, it was confirmed that the blockchain technology can be used as a tool to secure the reliability of the BIM model.

Korea is preparing an offshore carbon capture, transport and storage (CCS) demonstration project which is recognized as one of important $CO_2$ reduction technologies to mitigate climate change. The offshore CCS project aims to transport, inject and store large amount of $CO_2$ into offshore geologic formation, and has a potential risk of leakage which might cause disastrous damage to human health, environment and property. Therefore, in order to ensure the safety of the offshore CCS project, a strict HSE (health, safety and environment) management plan and its implementation are required throughout the project life cycle. However, there are no HSE domestic laws or regulations applicable to CCS projects, and the related research is insufficient in Korea. For the derivation of the essential and urgent requirement in HSE management framework applicable to the offshore CCS project in Korea, we analysed the HSE management methodologies and foreign CCS HSE management guidelines and cases. First, this paper has analyzed ISO 31000, a generalized risk management principles. Second, we have investigated the HSE management practices of CCS projects in Norway and UK. Based on the analyses, we suggested the necessity of developing the HSE Philosophy and the HSE management process through the whole life cycle. Application of HSE management in early phase of an offshore CCS project will promote systematic and successful project implementation in a cost-effective and safe way.

LCC(Life Cycle Cost) analysis on design process has to be performed for a selection of reasonable and economical design alternatives in highway construction projects. To be performed of LCC analysis, the maintenance data such that are maintenance periods, rate of repair, maintenance cost, and so on are required. Therefore the Hi-Portal System had been developed and the maintenance data has been accumulating in the Korean Expressway Corporation. However, the data are not effectively used because the system have no consideration for LCC concept, and currently, th data are acquired by survey with experts. In the study, it is proposed that the concept of Generally Annual Maintenance are practically and easily used to perform LCC analysis. Some of generally annual maintenance data are suggested through Hi-portal data analysis due to the proposed concept and LCC analysis of a real highway construction project is preformed by comparison with a current approach. From the results, it make sure that the proposed concept are effectively used to preform LCC analysis until during exactly practical data from Hi-Portal system are obtained.

Changes have occurred in the professional capabilities of the construction project managers after the global financial crisis. As representatives of construction companies and projects, construction project managers have full responsibility over a construction project. Throughout its life cycle, from design through construction to completion, the business capabilities of such managers are regarded as critical elements in the changes in the country's construction economy. Therefore, this study aimed to determine the main capabilities of current construction project managers, and to analysis of its competitiveness using Important-Performance Analysis(IPA). The results of IPA were as follows; (1)capability to win new contracts and capability to collect information of new project are needed for external relation competitiveness, (2)gerentocratic management mind-set and active breakthrough are needed for internal project management competitiveness, and (3)capability to predict issues and self-improvement are needed for self discipline competitiveness. However, this work is still considered to provide the basic data that can help Korean construction companies who plan to educate the project manager's strengthen their medium and long-term capabilities.

Recently construction industry has faced new era as following the advances of IT technology. It becomes possible that information and knowledge among people are exchanged actively thanks to computer-based tools. In fact, the tools, PMIS(Project Management Information System) and KMS(Knowledge Management System) already have been introduced to constuction industry successfully. Lately IETM(Interactive Electronic Technical Manual) is tried to be one of these systems. This trying is being enlarged that the IETM's concept is changed to administrative and legal process provider throughout the lifespan of construction projects. However, it is hard to define construction IETM in mega-scale project like urban regeneration project because construction projects are complex and have diverse stakeholders. These properties may make the IETM ambiguous system. To do define IETM as a administrative and legal process provider, this research will conduct survey and interview, then analyze its own properties and find out design strategies. Based on the properties and strategies, suggesting IETM's system demands and architecture of urban regeneration processes.

The wear of railway track affects loss of rough ride, noise or vibration of train and traveling safety. Moreover as the track is worn away, this promotes destruction of structural mechanism of rail track which can bring about increasing of rail track maintenance cost drastically. For this reason, it is very important and interested research subject to design railway track structure and to analyse train movement mechanism based on systematic analysis of the reasons causing rail wear possible in real field. In this research, for the efficient maintenance, Life Cycle Performance of rail track and maintenance characteristics are computed considering some track components such as track type, contracting type, sleeper type and roadbed type. Time - Wear probabilistic distribution relationship as well as multiple regression analysis based on time, curvature and wear data are computed to predict the service life remainder of railway track and to be adapted to safety assessment.
