Most of the conditions of contract applied in international construction contracts, including various conditions of contract published by FIDIC, include the provision for Retention Money which inevitably result in negative impact on cash-flow or financial burden to the contractors. In this study, fundamental reasons behind the application of Retention Money provisions are analysed and contractual mechanisms included in the FIDIC conditions of contract are searched, which include provisions for Performance Security and Defects as well as Termination, so that proper judgement can be derived on the application of Retention Money. In conclusion, considering the various contract provisions, performance security, termination of the contract by the Employer etc. included in the FIDIC conditions of contract, it is not necessary to include the provision for Retention Money.

Korean social structure is changing by leaps and bounds caused by industrialization, urbanization and information. Because of this, the sense of value, and moral consciousness of Korean people have been edteriorating and all kinds of social evils have been increasing also. However, the police who ought to be in charge of public well-being, security, social order are not playing their role on account of bad working conditions, and lack of budget. For this reason, individuals are desirous of preserving their security and lives at their cost. Private security has emerged at this background.

The South Korean Defense Ministry is planning and pushing forward to conduct a cloud computing pilot project in 2012. Taking into consideration the high-level security necessary in the military as well as wartime duties, if not designed properly, this project may anticipate severe damage to national security and interest. In particular, despite the fact that vulnerability due to inter-Korean confrontation and regular security-related incidents have been triggered, unconditionally conducting a cloud computing pilot project without reviewing not only violates security regulations but also causes various security-related side effects in and outside South Korea. Therefore, this thesis found conditions for conduct of this project by suggesting duties that can apply cloud computing as well as security technology, administration, post-accident matters and conditions for legally solving cloud computing in the military.

In the paper, we designed a context aware task-role based access control system(CAT-RACS) which can control access and prevent illegal access efficiently for various information systems in ubiquitous computing environment. CAT-RACS applied CA-TRBAC, which adds context-role concept for achieve policy composition by context information and security level attribute to be kept confidentiality of information. CA-TRBAC doesn't permit access when context isn't coincident with access control conditions, or role and task's security level aren't accord with object's security level or their level is a lower level, even if user's role and task are coincident with access control conditions. It provides security services of user authentication and access control, etc. by a context-aware security manager, and provides context-aware security services and manages context information needed in security policy configuration by a context information fusion manager. Also, it manages CA-TRBAC policy, user authentication policy, and security domain management policy by a security policy manager.

In the field of information security management systems, one of the representative certifications in Korea is ISMS-P certification, and internationally, ISO/IEC 27001 certification is recognized. When companies acquire both ISMS-P (or ISMS) and ISO/IEC 27001 certifications, budget and manpower are duplicated in similar areas. Therefore, it is necessary for the company to choose and invest in a certification that is suitable for its conditions. This paper proposes a strategy for obtaining information security management system certification that is suitable for the characteristics of the company, allowing for effective information security management based on the company's conditions. To achieve this, data were collected from the Ministry of Science and ICT's Information Security Disclosure System (ISDS), the Korea Internet & Security Agency (KISA), and the Financial Supervisory Service's Data Analysis, Retrieval and Transfer System (DART), and Probit regression analysis was conducted. During the Probit regression analysis, the relationships between seven independent variables and five cases of ISMS-P (or ISMS) acquisition, ISMS-P acquisition, ISMS acquisition, ISO/IEC 27001 acquisition, and both ISMS-P (or ISMS) and ISO/IEC 27001 acquisition were analyzed. The analysis results revealed the relationship between company characteristics, including industry, and certification acquisition in the ISMS field. Through this, strategies for certification acquisition based on company types could be suggested.

Security threats in the 4th Industrial Revolution have expanded to the issue of safety, but the environment for information security of domestic companies is still at a low level. This study aims to propose policy implications by empirically analyzing factors affecting investment intention. We investigated the state of information security and protection behavior and expanded UTAUT to investigate correlations. The results showed that information assets affect facilitating conditions, and perceived and new concerns have impacts on social influence. Social influence affect experience and habits, but the impact on security investment intentions was rejected. Facilitation conditions, previous experiences and habits have great influences on investment intention, new service security investment intention. The influence of perceived and new concern are low or rejected. There are moderating effects between types of business, size, security organization, experience of infringement, security personnel ratio, and personal information collection. This study will help to establish policies for enhancing the level of information security.

In the face of the serious security situation with the increasing threat from North Korea, Korean Army is pursuing a reduction in troops through the performance improvement project of the GOP science-based border security system, which utilizes advanced technology. In order for the GOP science-based border security system to be an effective alternative to the decrease in military resources due to the population decline, it must guarantee a high detection and identification rate and minimize troop intervention by dramatically improving the false detection rate. Recently introduced in Korean Army, the GOP science-based border security system is known to ensure a relatively high detection and identification rate in good weather conditions, but its performance in harsh weather conditions such as rain and fog is somewhat lacking. As an alternative to overcoming this, a radar-based border security system that can detect objects even in bad weather has been proposed. This paper proves the effectiveness of the AI-based scientific border security system based on radar that is being currently tested at the 00th Division through the 2021 Rapid Acquisition Program, and suggests the direction of development for the GOP scientific border security system.

Military Power is the most direct and actual measures for national security. For construction, maintenance, management of military power, the adequate expenditure is required but it is difficult to increase blindly owing to the lack of resources. There are security threats and economic conditions in determining of military expenditure. Republic of Korea has been more influenced by economic conditions than by security threats since 1990s In this paper, we analysed relation between real military expenditure and real GDP through regression analysis.

The final aim of South Korean policies on North Korea and reunification of Korean peninsula is to reflect the direction and the form which South Korean authority has been pursuing. To achieve this aim, we must establish the forms of reunification and continue to prepare for contingency plans while focusing our effort to those policies. In pursuing peaceful reunification, the national security should not be neglected. Moreover, the policing policy is one of the important national security policies. In order to draw up more effective policing policies in a reunified state, this dissertation establishes some preparing measures on policing conditions and expected problems resultion from the reunification of Korean peninsula after studying similar problems in formerly divided countries. The chapter one shows the direction of reunification policy. The chapter two looks some policing problems in formerly divided countries The chapter three studys the expected policing conditions and preparing measures after the reunification of Korean peninsula The chapter four reposes some reasonal solutions for peaceful reunification.
