Over the years, existing bridges have had various degrees of maintenance to extend the service life. As the existing bridges continue to deteriorate, however, each Department of Transportation (DOT) of the United States of America faces increasing demands on the limited funds available for bridge maintenance. Therefore, it is very important for State Department of Transportations to establish Maintenance, Repair, and Rehabilitation (MR&R) strategies for bridge structures such that funds get allocated for appropriate maintenance over the service life. This paper identifies the state-of-art and the state-of-practice of MR&R actions and the use of MR&R strategies in concrete bridge decks. In addition, a questionnaire survey was conducted to identify the type and timing for MR&R actions as well as existing MR&R strategies taken in concrete bridge deck by each DOT. This paper also presents the results of the survey.

Regarding the implementation of ROMM project (Rehabilitation, Operation, Maintenance & Management), which is one of overseas development projects, it is very important to diagnose the exact current status of aged thermal power plant. However, when people visit the power plant for the purpose of prediagnosis to implement the ROMM project, most target power plants for diagnosis, in general, are under operation. This can be a big interference factor to diagnose the exact current status of power plants. Therefore, in order to solve such interference factor, based on the 30 years of know-how in the field, the present study has developed a regression curve for a simple life time assessment and the calculation of rehabilitation cost that may be used as a reference relatively for the quantitative diagnosis on the status of a relevant power plant even during the operation of the power plant.

The industrialized countries have promoted the rehabilitation of existing housing units as a national agenda, such as green policies, whereas korea, although having a housing stock as huge as that of world countries, have focused on the growth of housing by constructing new units rather than rehabilitating existing ones. Today, it has been so long since many multiple dwellings in Seoul and in the vicinity of Seoul were constructed. There were, however, very few political efforts to encourage the rehabilitation of housing. Today, substantial time has passed since multiple dwellings in Seoul and the first-stage new cities such as Bundang and Ilsan were constructed. What is required to maintain the quality of the existing housing and use it with safety is to promote the engineer of maintenance for multiple dwellings to work the maintenance of existing multiple dwellings. The objective of this study is to compare and analyze the maintenance qualification system of multiple dwellings of Japan, and then to propose to raise engineers of maintenance for multiple dwellings in korea.

Life-Cycle Cost Analysis (LCCA) for highway projects is known as an effective analytical technique that uses economic principles to evaluate long-term alternative investment options, especially for comparing the values of alternative pavement design structures and construction strategies. In the Unites States, the 2012 Moving Ahead for Progress in the 21^st Century Act (MAP-21) amended the United States Code to mandate that the United States Government Accountability Office (GOA) conducts a study of the best practices for calculating life-cycle costs and benefits for the federally funded highway projects in 2013. The RealCost 2.5CA program was developed and adapted as an official LCCA tool to comply with regulatory requirements for California state highway projects in 2013. Utilization of this California-customized LCCA software helps Caltrans to achieve substantial economic benefits (agency cost and road user cost savings) for highway projects. Proper implementation of LCCA for roadway construction and rehabilitation would deliver noticeable savings of agency's roadway maintenance cost especially in developing counties where financial difficulties exist.

Objectives : It is sure that standardization of medical instruments is very important and necessary. Cupping therapy is one of the traditional oriental medical method, and it is necessary to set up a standard of cupping therapy and instruments. Methods : We select 3 major cupping instrument makers according to a questionnaire survey of 2001 oriental medical doctors. Dae Gun is A maker, Han Sol is B maker, Dong Bang is C maker. And with these air pumps we make experiments on stability by an inner impact test and a falling test. With these cups we check stability by an inner impact test and a disinfection test. And to know function of these instruments we test a negative pressure and maintain attached cups until 5 to 10minutes. Results : All results of experiments(impacted test, disinfection test, falling test) on stability of cups and air pumps are suitable for medical instrument. And the efficiency of 3 major makers shows various results. Negative pressure of B group is the highest, C group is the second, A group is the lowest. Pressure maintenance test shows A and C group is comparatively up to the experimental standard(<10%), B group is comparatively below the experimental standard(<10%). Conclusions : Results show stability of cups and air pumps is suitable for medical instruments. And negative pressure of cupping and maintenance of pressure show various results. So it is necessary to set up a standard negative pressure of cupping and maintenance of pressure.

In this study, the behavior of R/C beams strengthened with carbon fiber laminate (CFL) is analyzed from the test results. CFL is attractive for this application due to its good tensile strength and low weight. Test parameters are the width and the thickness of CFL and repair of damaged specimen. The failure mode and ultimate load are analyzed from these measured data. Test results show that the peak load of specimens strengthened with CFL is increased to 1.27~2.04 times that of non-rehabilitation specimen. The wider lap width, larger amount of CFL, the larger strength is obtained. But the ductile behavior of the rehabilitated specimens is inversely proportional to the CFL thickness.
