Zhi-feng Shu,Xian-kang Dou,Hai-yun Xia,Dong-song Sun,Yan Han,Hyunki Cha,김덕현,Guo-cheng Wang,백성훈,Dong-dong Hu 한국광학회 2012 Current Optics and Photonics Vol.16 No.2
A mobile Rayleigh Doppler wind LIDAR at an eye-safe wavelength of 355 nm incorporating double-edge technique with triple-channel Fabry-Perot etalon is developed for wind measurement from 5to 40km. The structure of this LIDAR system is described. An intercomparsion experiment with rawinsonde is made, showing good agreement with expected measurement accuracy. A continuous observation of stratosphere wind field for several days with temporal resolution of 15 min and spatial resolution of 200 m from 5 to 40 km is presented, demonstrating the stability and robustness of the LIDAR. A stratospheric quasi-zero wind layer can be found at around 20 km with a direction change from east to west evident in the continuous observation.

Objective: This study was conducted to determine the effects of dietary maifanite supplementation and fecal collection method on the apparent total tract digestibility (ATTD) of calcium (Ca) and phosphorus (P) and blood parameters in growing pigs. Methods: Thirty-six growing barrows (Duroc×Landrace×Yorkshire; 27.0±2.6 kg) were allotted to six dietary treatments with 6 pigs per treatment according to body weight in a completely randomized design. The experimental treatments were: i) Low Ca+cornstarch (2.25%), ii) Low Ca+maifanite (2.25%), iii) Medium Ca+cornstarch (1.42%), iv) Medium Ca+maifanite (1.42%), v) High Ca+cornstarch (0.64%), and vi) High Ca+maifanite (0.64%). Feces were collected by the total collection (TC) and indicator method (IM). At the beginning and the end of the experiment, blood samples were collected from each pig. Results: For the TC method, there were no difference in Ca intake, fecal Ca output, Ca retention and the ATTD of Ca between cornstarch and maifanite diets at the same dietary Ca level. However, urinary Ca excretion was lower (p = 0.01) in pigs fed low Ca diets without maifanite supplementation compared with other dietary treatments. Dietary maifanite supplementation had no effect on the P metabolism in growing pigs. For the IM method, there was no difference in Ca digestibility between cornstarch and maifanite diets at the same dietary Ca level. The ATTD of P was greater (p<0.01) in pigs fed the high Ca diet with maifanite supplementation compared with the high Ca diet with cornstarch treatment. Dietary inclusion of maifanite had no effect on blood parameters in growing pigs. Conclusion: Dietary maifanite supplementation had no effect on the ATTD of Ca and P and serum parameters in growing pigs. The IM resulted in lower digestibility values than the TC method.

Instantaneous relay (relay-without-delay) using interference alignment is a promising approach to neutralizing interference and improving system capacity. In Wang Chenwei`s work, a 2-user scenario required both source and relay to access the global channel state information (CSI). This paper shows a new method of interference alignment improves the degrees of freedom (DoF) prominently for the 3-user MIMO interference channel with instantaneous relay. This new method is focused on the relay node that completes the alignment interference neutralization so the global CSI is obtained only once and the pressure on the base station can be mitigated. In addition, the 3-user MIMO interference channels with instantaneous relay can achieve 2M DoF when source and destination have M antennas, respectively. This method shows 33% improvement over the conventional method using interference alignment which obtains 3M/2 DoF.

Purpose: This study aimed to assess possible interactive effects of coping styles and psychological stress on depression and anxiety symptoms in Chinese women shortly after diagnosis of breast cancer. Methods: Four hundred and one patients with breast cancer were face-to-face interviewed by trained research staff according to a standardized questionnaire including information on socio-demographic characteristics, psychological stress, coping styles, and anxiety and depressive symptoms. Interactive effects were assessed by hierarchical multiple regression analyses. Results: There were significant associations of the four domains of psychological stress with anxiety and depressive symptoms except for the relationship between "worrying about health being harmed" and depressive symptoms. "Abreaction coping behavior" and "escaping coping behavior" significantly increased the level of both anxiety and depressive symptoms; whereas an "active coping style" reswulted in significant decrease. The interaction of "active coping behavior" with "worrying about health being harmed" significantly increased the risk of the anxiety symptoms, while adopting "self-relaxing coping behavior" was associated with significant decrease. The interaction of "worry about daily life and social relationship being restricted" with "escaping coping behavior" significantly increased the risk of the depressive symptoms. Conclusions: The results of this study suggest that certain coping styles might moderate the association of psychological stress with anxiety and depressive symptoms in Chinese women with breast cancer.
Physicochemical Property of Pumpkin Slices Dehydrated with Red Algae Extract

Pumpkin ($Cucurbita$ $maxima$) slices dehydrated with red algae extract (RAE) at 40% (w/w), and the dried samples were compared with freeze- and hot-air-dried samples for functional qualities. Rehydration ratios of freeze- and hot-air-dried, and RAE-treated samples were 5.79, 5.25, and 11.09 g/g, respectively. The RAE-treated samples had better results than those of freeze-dried or hot-air dried samples in terms of color and sensory evaluation. Total carotenoid content of the RAE-treated samples ($574.54{\mu}g/g$) was lower than that of the freeze-dried samples ($636.62{\mu}g/g$), but higher than that of the hot-air dried samples ($235.27{\mu}g/g$). These results suggest that pumpkin slices can be dehydrated with RAE to preserve quality during storage.
