  • Purpose: Since September 1st, 2013, subjects of the evaluation have been expanded, and the evaluation standard has been detailed to enable Building energy rating system for all buildings. Accordingly, the new evaluation program (ECO2) has been developed, and therefore, apartment applied after September 1st, 2013 were evaluated with the new evaluation program. Therefore, this research suggests the improvement plan to figure out reasons for the evaluation result calculation and to calculate the evaluation results close to the actual energy usage by analyzing and comparing primary energy consumption as a result of the new evaluation program (ECO2) and actual heating energy usage on the same building. Method: When comparing evaluation results of the new evaluation program (ECO2) and actual heating energy usage, the tendency was similar but different. Also when comparing seasonally, the tendency was similar, but the different between actual heating energy usage and primary energy consumption during winter is greater than during spring or fall, and when comparing seasonal electric usage, heating alternatives were used through increased electrical usage during winter compared to during spring or fall. Result: Therefore, when evaluating apartment with the new program (ECO2) in the future, evaluation items relevant to the use of heating alternatives should be added, and the modification factor should be added according to the region. Based on the evaluation results of the research and actual energy usage, the Modification factors of the central part and the southern part were calculated respectively as 0.5 and 0.8.

  • Objectives : Investigation of the antidepressant effect of Glycyrrhizae Radix (GR) through the anti-inflammatory effect. Methods : Depression in rats was induced by LPS (i,p.3days). The rats were treated with GR100 mg/kg (GR 100) or GR400 mg/kg (GR 400). The depressive immobility was examined with Tail Suspension Test(TST) and Forced Swimming Test(FST). The expression of nuclear factor-${\kappa}B$(NF-${\kappa}B)$, $I{\kappa}B$ was measured with western blotting. The concentration of corticosterone, cytokine in plasma was measured with ELISA. The expression of c-Fos in the paraventricular nucleus(PVN) and tyrosine hydroxylase(TH) in the locus coeluleus(LC) were measured with immunostaining method. Results : In the TST, GR400 group significantly decreased immobility time compared with the LPS group. In the FST, GR100, GR400 group significantly decreased immobility time comparing with the LPS group. c-Fos expression in GR100 and GR400 group was decreased comparing with the lipoplysaccharide(LPS) group. The $I{\kappa}B$ expression of GR100 and GR400 group was increased comparing with the LPS group. The level of corticosterone of GR100 group was decreased comparing with the LPS group. The concentration of cytokine of GR100 and GR400 group was decreased comparing with the LPS group. TH expression in the LC was increased in LPS group, but in GR100 and GR400 group was not shown significant decrease. Conclusion : According to this results obtained, GR has antidepressant effects by the anti inflammatory action through the suppression of HPA axis activity, not through the action against the catecholaminergic system.
