<P><B>Abstract</B></P><P>The goal of this study was to evaluate the reliability and validity of the Korean version of the Brief Fatigue Inventory (BFI-K). One hundred seventy-eight cancer patients and the same number of age- and sex-matched control subjects completed the BFI-K, the European Organization for Research and Treatment of Cancer QLQ-C30 (EORTC QLQ-C30), the Beck Depression Inventory (BDI), and a Brief Pain Inventory (BPI). The Cronbach's alpha coefficient for the BFI-K was 0.956 in the cancer patient group and 0.955 in the control group. The global score and nine of the single item scores for the BFI-K were significantly correlated with the fatigue and global health status/QoL subscale of the EORTC QLQ-C30, BDI, and BPI (coefficient range 0.38–0.66). Discriminant validity showed that BFI-K could distinguish significant differences of performance status between subgroups of patients, and between the cancer patient group and the control group, as expected. Our study has shown that the BFI-K is a reliable, valid self-rating instrument in terms of its psychometric properties.</P>

A high spectral resolution lidar (HSRL) system based on injection-seeded Nd:YAG laser and iodineabsorption filter has been developed for the quantitative measurement of aerosol and cloud. The laserfrequency is stabilized at 80 MHz by a frequency locking system and the absorption line of iodine cellis selected at the 1111 line with 2 GHz width. The observations show that the HSRL can provide verticalprofiles of particle extinction coefficient, backscattering coefficient and lidar ratio for cloud and aerosolup to 12 km altitude, simultaneously. For the measured cases, the lidar ratios are 10~20 sr for cloud,28~37 sr for dust, and 58~70 sr for urban pollution aerosol. It reveals the potential of HSRL to distinguishthe type of aerosol and cloud. Time series measurements are given and demonstrate that the HSRL hasability to continuously observe the aerosol and cloud for day and night
