This study is to determine an optimal yacht mooring location candidate among many alternative candidates in order to obtain the maximized efficiency under the natural conditions using integer programming. To deal with marina's construction location, the optimal construction location is selected using 21 important factors analysis for 4 candidates in the Mokpo city. The development period and the initial investment cost weight are one and half times more than the others among 21 factors. The optimal spiral analysis of weighted linear model shows that the Peace Square sea area is selected as the most optimal place among 4 candidates. This proposed model has not been applied in the optimal marina's facility candidate selection problem yet. This paper will contribute to determine the most reasonable alternative. Also, this proposal model can be applied to other marina's facility candidate selection problem in other regions.

This study analyzed the economic analysis on the Cambodian inland waterway from Phnom Penh to Chong Kneas. The social discount rate of 3.5% was applied for the cost and benefit of projects and converted to the current values in 2009. The benefits were supposed as the triangle distribution with minimum, mode, and maximum value corresponding to pessimistic, moderate and optimistic prospect separately. And the distributions of costs were the normal. As the result of probabilistic simulations, the average of B/C for scenario A showed relatively the highest with 0.25 and its 90% confidence interval 0.16~0.35. The average B/C of scenario B is 0.10 with the 90% confidence interval 0.06~0.13 and the one of scenario C is 0.15 with 90% confidence interval 0.12~0.19. Therefore it was concluded as low economic feasibility to install inland waterway aids to navigation along the surveyed waterway. However, the performance of the project should be determined by its political analysis as well as the economic.

Nuclear power plant(NPP) is a large-sacle national infrastructure with total project cost of 77 billion dollars and period of 10 years or more. Moreover, since it is operated over 60 years, NPP is a facility closely related to national economy and public safety. Therefore, accurate information and consistent physical configuration should be maintained to enable accurate and economical decision making in NPP project process such as design, construction, operation, and decommission. Since NPP industry is more complicate and regulated than other industries, the importance of configuration management(CM) has been widely recognized in the early days. However, there were limitations in implementing systematic CM due to unclear purpose and subject. Therefore, this paper suggests a room-based database for CM in NPP reflects design requirements and facility configuration information.

This paper investigates housing defects and housing satisfaction of the aged according to the personal characteristics and their housing environment. Personal interview was made on the 280 senior persons living in Jeonbuk area. Research results are following. Low levels were found in education, self privately-owned property, monthly income. Most of them live in a detached house that is outdated and obsolete. The facility defects of housing were the most serious level in case of the female senior citizen who lives alone. Their house aging was old but had the high deviation among households. Main influencing factors on facility defects of housing were perceived economic status and ownership of house, the next was age of the aged. Main influencing factors on the housing satisfaction were perceived economic status. Housing satisfaction was higher, the better economic level of the aged was, male than female, the less the age was, in case of hot-water usage in bathroom, owner of houses, no difference in floor level, larger storage space of kitchen was. According to the empirical results, we propose the supporting policy of hosing safety for the aged in order to reduce the risk and social cost. Especially the rate of population aging, the aged household, and the detached houses are higher in Jeonbuk rural areas than the other area. Housing facility defects of the elder who lives alone and house aging of theirs are serious level. Local government should have supporting system that considers local difference and characteristics of the aged housing.

The increasing concern over radiation exposure in the nuclear industry has fostered agrressive efforts to reduce the levels of radiation exposure. One area of the effot to reduce the radiation exposure is the development of a remote radiation monitoring system. Remote radiation monitoring can serve many benificaial functions reduce exposure to radiation by plant personnel, impruve the quality of the data that is collected and recognize the radiation environment easily. Radiation mapping system gives a good information that represents radiation level distribution. The system we have developed consists of a data acquistion parts, mobile robot and remote control parts. Data acquisition parts consist of radiation detection module and vision acquistion module which collect radiation data, visiion data and distance information. In remote control parts, the acquision data are processed and displayed. We have constructed radiation mapping image by overlaying the vision and radiation data. The radiation mapping techniques for displaying the results of the survey in an easily comprehendable form will facilitate a better understanding of the radiation environment in the facility. This system can reduce workers radiation exposure and aid to help work plan, so it has significant benifits in cost and safety.

Nuclear energy programs around the world increasingly find themselves at the nexus of potentially conflicting demands from both domestic and international stakeholders. On one side, the rapid growth in demand for electricity coupled with the goal of reducing carbon emissions calls for a significant expansion of nuclear energy. On the other, stakeholders are seeking ever greater safety, environmental, security, and nonproliferation assurances before consenting to the construction of new nuclear energy facilities. Satisfying the demand for clean energy supplies will require nuclear energy operators to find new and innovative ways to build confidence among stakeholders. This paper discusses two related concepts which can contribute to meeting the needs of key stakeholders in cost effective and efficient ways. Structured processes and tools for assessing stakeholder needs can build trust and confidence while facilitating the "designing-in" of information collection systems for new facilities to achieve maximum efficiency and effectiveness. Integrated approaches to monitoring facilities and managing the resulting data can provide stakeholders with continued confidence while offering operators additional facility and process information to improve performance.

Rebar work is important in terms of cost and process of reinforced concrete construction along with formwork and concrete construction, and the quality of reinforced concrete construction has a great influence on the safety and durability of the structure. Therefore it is important to thoroughly inspect the steel reinforcement after casting the concrete because it is difficult to confirm the actual condition of the reinforcement. The purpose of this study is to develop an augmented reality system to visualize the records of bar placing work, which is increasingly utilized in the construction field. In order to improve maintenance of reinforced concrete, this study suggests a plan to effectively manage the drawing information including the structural drawing, the placing drawing, and the photographed image at the construction and inspection stage, and develop a system that utilizes augmented reality technology that can display the state of the inside of a concrete structure by superimposing it on actual environment.
