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.

최근에 국제물협회(IWA)는 수도서비스분야에 대한 새로운 수행능지표를 제안하였고 이의 성공적인 적용사례가 연이어 보고되고 있다. 이들 보고에 따르면, 특히 급수전당의 물소비량이 크게 차이나는 지역들 간에는 백분율을 이용한 지표를 이용하여 수행능을 비교하지 말아야 한다고 말하고 있다. 그러나 아직까지 한국에서는 백분율을 이용하는 지표들 중의 하나인 유수율이 수도행정의 목표를 수립하기 위해 가장 중점적으로 사용되고 있으며, 시스템간의 물손실관리 수행능을 비교평가 하는 데에 널리 사용되고 있다. 이에 본 연구에서는 전국적인 상수도 및 지역통계 자료를 이용하여 백분율지표의 비합리성을 밝히고 보다 효율적인 물손실관리를 위하여 어떤 것이 보다 바람직한 수행능지표인지를 제안하고자 하였다. 3년간의 상수도 및 지역통계 자료를 이용하여 전국의 도시지역에 대하여 유수율, 실손실율, 1인 당 실손실량, 급수전 당 실손실량, 및 IWA의 누수평가지표(ILI)를 산정하고, 각 대상지역을 비교 평가한 결과에 따르면, 백분율을 이용한 지표 즉, 유수율 및 실손실율은 지역 조건이 크게 차이나는 곳 간의 수행능을 제대로 비교하지 못하는 반면, 급수전 당 실손실량 및 누수평가지표는 수행능을 효율적으로 비교, 평가하는 것으로 나타났다. 또한 유수율이 높게 나타나는 지역에서도 하나의 급수전 당 손실되고 있는 물의 양이 매우 클 수 있다는 것을 보여주었다. 따라서 수도사업자의 물손실 관리에 대한 수행능을 보다 합리적으로 평가하여 물손실 문제에 쉽게 접근하고, 문제를 효율적으로 해결하기 위해서는 급수전 당 실손실량 혹은 누수평가지표를 이용하는 것이 바람직하다고 판단된다.
