Objectives: This study was performed to develop the indicators for national surveillance of chronic disease, which is a governmental concern to manage the chronic disease for older persons. It is necessary that chronic disease surveillance system needs to be made in Korea for effective management of chronic diseases. With the system, we know the prevalence and incidence of chronic diseases, observe the trend of utilization for caring the chronic diseases, and analyze the behavior change for prevention of chronic diseases. Methods: This study was carried out by analyzing the data by which the indicators was produced, by reviewing how the United States made the indicators. By benchmarking the United States, the sources of data of the national surveillance indicators for chronic diseases in Korea were compared. Results: In this study, the most significant indicators were identified and proposed to improve the surveillance indicators by changing the sources of data. These findings warrant further development of the health policy for the chronic disease prevention and establishment of the chronic disease surveillance system. Conclusions: The results of this study can be used to develop national surveillance indicators to manage the chronic diseases and can be used as basic data to develop community health programs.

Plant Configuration Management(CM) is an activity to maintain consistency of design requirements, physical configuration, facility configuration information throughout the life cycle of the plant by systematically managing changes that occur during the plant design and operation process. Conformity between information must be ensured not only in the design stage, but also in the case of design changes in the operation and maintenance stages, and thus a computer system capable of efficiently managing them is required. In particular, in consideration of an application to small and medium-sized domestic plants, a computer system that can support configuration management at a low cost is needed. Accordingly, in this study, a configuration management system has been developed to support the management of plant design information and change procedures in the operation stage of small and medium-sized plants. Here, a case for quantitatively evaluating the effectiveness of the developed system is described.

Our study was carried out to analyze the variation factors of severity-adjusted length of stay(LOS) in coronary artery bypass graft(CABG). The subjects were 932 CABG inpatients of the Korean National Hospital Discharge In-depth Injury Survey from 2004 through 2008. The data were analyzed using $x^2$ test and the severity-adjusted model was developed using data mining technique. The results of the study were as follows: male(71.1%), older than 61 years of age(61.6%), more than 500 beds(92.8%) and admitting via ambulatory care(70.0%) appeared to have higher rate than otherwise. In-hospital mortality of CABG inpatients was 2.8%. In addition, 46.4% of the patients received their care in other residence. The angina pectoris(45.6%) was found to be the highest in principle diagnosis, followed by chronic ischemic heart disease(36.9%) and acute myocardial infarction(12.0%). We developed severity-adjusted LOS model using the variables such as gender, age and comorbidity. Comparison of adjusted values in predicted LOS revealed that there were significant variations in LOS by location of hospital, bed size, and whether patients received the care in their residences. The variations of LOS can be explained as the indirect indicator for quality variation of medical process. It is suggested that the severity-adjusted LOS model developed in this study should be utilized as a useful method for benchmarking in hospital and it is necessary that national standard clinical practice guideline should be developed.

Recently International Water Association(IWA) has proposed new performance indicators for water supply services and their successful applications are being reported continually. According to the various reports, the percentage indicators were suggested not to be used for performance comparison, especially where the targeted areas have great difference in consumption per service connection. But unfortunately in Korea the revenue water ratio, one of the percentage indicators is still being used to set up the goal of water-related administration and to compare the performances between systems. Therefore this study aimed to prove the inapplicability of the percentage indicators with nation-wide data and to suggest better performance indicators for more efficient water loss management. According to the result of the comparison of various performance indicators with conventional one, it is roved that percentage indicators ca not evaluate the performance efficiently where the local situations are significantly different. It is suggested that the better performance indicators such as real losses per service connection or ILI should be used to benchmark the performances of water suppliers on water loss management so thai the problems of water losses could be identified easily and recovered effectively.
