As annual energy consumption rates in the Korean built environment are significantly increasing every year, deployment of building energy management system (BEMS) needs to be more encouraged and be thoroughly implemented in order to fundamentally reduce building energy consumption rate. However, its successful deployment and thorough implementation require understanding of the status and trends of BEMS in the domestic and overseas building sector. Clear understanding of the role of BEMS and its performance assessment items and assessment indices can significantly improve the performance level of BEMS. This study aims at suggesting assessment indices for evaluating energy saving performance using AHP analysis in operating energy saving control as a base of impact of energy saving control on energy usage in building through analysis of building composition element and saving control element. To this end, weighting ratio of composition element are suggested using AHP method over energy management specialists and the items composing assessment indices are verified through the consensus among the domain experts. In addition, the assessment indices were applied to four real-world BEMS operated buildings in order to evaluate their energy saving performance and to demonstrate the feasibility of the proposed assessment method. As a result of verification of assessment indices suggested in this study, it is necessary to further integrate various kind of saving control schemes into the current energy saving control items if items of assessment indices is to reach the goal of energy saving. Also, it is necessary to consider adoption ratio of energy saving control item and degree of level of application item, additionally, in order to make up for degree of energy saving control.

Purpose: The aim of this study was to examine the sensitivity and specificity of the influenza rapid antigen test, in comparison with reverse transcription polymerase chain reaction (RT-PCR), according to the time of the test from symptom onset and the clinical manifestations in the patients tested for suspected infection of the influenza A (H1N1) at a second hospital. Methods: A total of 529 pediatric patients, aged between 6 and 12 years old, who visited the emergency department from October 1, 2009 to December 31, 2009, received the influenza rapid antigen test and RT-PCR. We examined the sensitivity and specificity of the influenza rapid antigen test in comparison with RT-PCR according to the time of the test from symptom onset (<24 hours, 24 to 48 hours, 48 to 72 hours, >72 hours) and clinical manifestations (fever, cough, rhinorrhea·nasal obstruction, sore throat, gastrointestinal symptoms, and general symptoms) in a retrospective study based on hospital charts. Results: The sensitivity of the influenza rapid antigen test at elapsed times of less than 24 hours, 24 to 48 hours, and 48 to 72 hours after the onset of the symptoms was 53.9%, 61.4%, and 62.1% respectively. When the elapse time was greater than 72 hours, the sensitivity was 31.6%; thus, the sensitivity of the influenza rapid antigen test tended to decrease with elapsed time. The sensitivity of the test was 79% in patients presenting with gastrointestinal symptoms, which was the highest, but there was no statistical difference according to the clinical manifestations of the patients. Conclusions: Our study suggests that more accurate results might be gained when the influenza rapid antigen test is performed within 72 hours after symptom onset.
