<P><B>Purpose</B></P><P>To determine changes in autonomic nervous system activity after treatment in men with lower urinary tract symptoms (LUTS), we evaluated changes in patients' symptoms, uroflowmetry, and heart rate variability (HRV) after treatment with alpha-blockers for 12 weeks.</P><P><B>Materials and Methods</B></P><P>Ninety-five men who had LUTS (International Prostate Symptom Score [IPSS] ≥8) were included in this study. We divided them into two groups on the basis of a low frequency/high frequency (LF/HF) ratio of 1.6. After treatment with Xatral XL (Handok Inc., Korea) 10 mg for 3 months, we rechecked their IPSS, uroflowmetry, HRV and compared these with the baseline measurements.</P><P><B>Results</B></P><P>Fifty-four men were assigned to the low LF/HF group (group A: LF/HF ≤1.6) and 41 men to the high LF/HF group (group B: LF/HF >1.6). At baseline and 12 weeks, none of the parameters differed significantly between the groups except for HF, which is one of the parameters of HRV. IPSS, the IPSS-voiding subscore, and the IPSS-storage subscore decreased and maximal uroflow increased significantly after 12 weeks of treatment. Whereas the baseline LF/HF ratio increased from 0.89±0.407 to 1.80±1.804 after treatment in group A, it decreased from 3.93±5.471 to 1.79±1.153 in group B.</P><P><B>Conclusions</B></P><P>The efficacies of Xatral XL were clear in both groups. We found that the LF/HF ratio in the two groups merged to a value of approximately 1.79 after treatment. We suggest that this could be a clue to the importance of balance in autonomic nervous system activity in men with LUTS.</P>

The most important factor of mobile robot is to build a map for surrounding environment and estimate its localization. This paper proposes a real-time localization and map building method through 3-D reconstruction using scale invariant feature from monocular camera. Mobile robot attached monocular camera looking wall extracts scale invariant features in each image using SIFT(Scale Invariant Feature Transform) as it follows wall. Matching is carried out by the extracted features and matching feature map that is transformed into absolute coordinates using 3-D reconstruction of point and geometrical analysis of surrounding environment build, and store it map database. After finished feature map building, the robot finds some points matched with previous feature map and find its pose by affine parameter in real time. Position error of the proposed method was maximum. 8㎝. and angle error was within 10°.
