In this paper, we develop a facility management system which provides fault effect and replacement alarm function of each component for supporting effective maintenance of facility. To do this, we use weighting method to each component, calculate importance of each component, and make them to hierarchy structure using bill of materials of facility. Also, we draw fault cause and fault effect of components based on failure modes effects and criticality analysis, and define criteria of severity, occurrence and detection to get risk priority number. To apply these concepts, we develop and test the facility management system to verify its practicality. In the future, we expect the developed system to apply many domains such as maintenance of ship and offshore plant.

Research of ubiquitous computing becomes more popular topic along with the rapid development of wireless technologies. Firstly, research and development on RFID focuses on manufacturing and retail sectors, because it can improve supply chain efficiency. But, it changes to USN (Ubiquitous Sensor Network) by adding a sensor and wireless network technologies on it. In this research, we design and implement the electric facility management service framework to collect real time information of electric facility using RFID/USN. In electric power industry, it is important the supply of energy must be guaranteed. So many power utilities control and supervise the transmission line to avoid power failures. Utilities install many types of sensor to monitor important facilities by wired network such as optical cable and PLC. In this research, we develop the sensor node which is small, easy to install and using wired network. We design the service framework for electric facility management to collect data using RFID tag, reader and wireless sensor nodes and implement the electric facility management service.

The purpose of this study is to analyze the efficiency of Korean child welfare facilities using the DEA analysis method and to present policies. The input variables for the analysis of this data were the number of employees, the number of facilities, and the number of gardens, and the output variables were the current sources. The results of the study are as follows. As a result of CCR analysis, inefficient facilities were found to be temporary protection facilities and comprehensive facilities. As a result of BCC analysis, inefficient facilities were identified as temporary protection facilities. As a result of SE analysis, inefficient facilities were found to be temporary protection facilities. The suggestion is as follows. First, adjustment of the capacity of temporary protection facilities is required. Second, it is necessary to strengthen the professionalism of workers in child welfare facilities. Third, strengthen the expertise of the child welfare facility manager.

Purpose : The information of mental health facilities in Korean law is so unclear that people hardly enable to understand what sort of proper mental health service is prepared for them. Futhermore, there is not enough regulation and standard to classify each type of facilities in the law. Therefore the purpose of this study is to provide data on the basis for classification and facility standards by analysing Korean law and policies. Methods : This study was conducted by a research on law and regulation of mental health facility. Results : The result of this study can be summarized into three points. The first one, current law and policy do not reflect a change in community mental health services paradigm. The second one, the classified facility should be designed to fit the community mental health services. The third one, overall, it requires more detailed guidelines to enhance the quality of mental health services. Besides, the treatment as well as the function of the prevention and rehabilitation are necessary criteria that can also be enhanced. Implications : This study looked at the classification and facility standard of mental health facility by the change in community mental health services paradigm. Forward according to these changes, there is a need for specific guidelines for mental health facility.

Purpose: The purpose of this study was to determine if monocular and binocular accommodative facility tests would be useful in diagnosing general binocular dysfunctions. Methods: 95 symptomatic children, who were selected from comprehensive vision tests, were classified into four groups (29 subjects with accommodative dysfunctions, 28 subjects with vergence dysfunctions, 25 subjects with combined accommodative and vergence dysfunctions, 13 subjects with normal binocular functions). Monocular and binocular accommodative facility was measured with ${\pm}$2.00 D flipper lenses. Results: Statistical analysis revealed that binocular accommodative facility measurement was significantly lower than monocular accommodative measurement in the vergence dysfunction group (p<0.01). However, there were no differences between monocular and binocular accommodative facility measurements in the group of accommodative or combined accommodative and vergence dysfunction (p>0.05). In addition, subjects with general binocular dysfunctions performed significantly poorer than subjects with normal binocular function on monocular and binocular accommodative facility (p<0.000). Conclusions: As a result of this study, monocular and binocular accommodative facility test, which could differentiate dysfunction from normal as well as between dysfunctions, indicated useful means for diagnosis of general binocular dysfunctions.

The plan of developing a fishing village and port will be indirectly funded by the government. In the short term, there will be five different multi-functional fishing village models which are based on the first industry to attach to the third industry of marine sports experience tourism. In the long run, they have to be reached gradually. The popular scenic spot of the marine sports experience tourism is made by human resources and fundamental installations considering that it must be done in unpolluted water. It is necessary to separate the fish harbor into two sides. One side is an existing fishing industry. The other side is made up of several pontoons for the marine sports equipment of the marine mooring. It is necessary to build facilities, such as the mooring facility, the storage facility, the repair-check facility, supply-cleaning facility, information booth, accommodations, education facility, and a marine culture exchange facility.

A rainwater utilization facility consists of its catchment area, treatment facility, storage tank, supply facility and pipes in general. The rainwater storage tank which occupies the largest area of the facility has been usually considered quantitatively for determining the storage capacity. Hence, there is little information on water quality improvement by sedimentation in a rainwater storage tank in operation. In this study, we measured the rainwater quality in a rainwater storage tank in operation during late spring and summer, and showed water quality improvement of turbidity removal of 25~46% by sedimentation in a rainwater storage tank under a fixed water level without inflow and outflow after runoff ceased. It is necessary to have a considerable distance between the inlet and outlet of the tank and, if possible, it is recommended that the design should allow for an effective water depth of over 3 m and supply rainwater near the water surface. The operation method which increases the retention time by stopping rainwater supply for insuring low turbidity is recommended when the turbidity of rainwater runoff is high. And also more efficient operation and maintenance of the rainwater utilization facility is expected through the tailored design and operation of the facility considering particle removal and behavior.

The purpose of this study is to promote the use of cultural facilities of North Korean refugee mothers with young children by finding out their past experience of cultural facility use. The subjects of this study were 183 North Korean refugee mothers with young children and a total of four research participants. A survey and in-depth interviews were used to draw reliable research results. The research results are as follows: First, as to uses of cultural facilities, North Korean refugee mothers with young children got information about cultural facilities through the Internet community such as Internet cafes and blogs. Their considerations for using cultural facilities were diversity of activity programs and subdivision of performances and arts activities. Over 50% of mothers responded that cultural facilities were needed to enhance the creativity of their children. Second, concerning difficulties of cultural facility use, the most difficulty was high costs, and the second most difficulty was absence of cultural facilities nearby their residence. Third, as to the needs of cultural facility use, a children's library was needed the most for children's development. They responded that the most necessary policy for cultural facility use was to increase cultural vouchers for low-income households and to expand recipients of these vouchers.

In this paper, we suggest a checkpoint and recovery facility for the fault-tolerable process which is expected to be executed for a long time. The basic concept of the suggested facility is to allow the process to be executed continuously, when the process was stopped due to a System fault, by storing the execution status of the process periodically and recovering the execution status prior to the fault was occurred. In the suggested facility, it does not need to modify the source code for the fault-tolerable process. It was designed for the user to specify directly the file name and the checkpoint frequency, and two system calls(save, recover) were added. finally, it was implemented on the Linux environment(kernel 2.4.18) for checking the feasibility.
