Different power output of solar cells can be observed at high-temperature regions such as desert areas. In this study, performance dependence on operating temperature of crystalline silicon solar cells with different emitter types was analyzed. Based on the light current-voltage (LIV) measurement, temperature coefficients of short-circuit current density ($J_{SC}$), open-circuit voltage ($V_{OC}$), fill factor (FF) and power conversion efficiency were measured and compared for two groups of crystalline silicon solar cells with different emitter types. One group had homogeneously doped (conventional) emitter and another selectively doped (selective) emitter. Varying the operating temperature from 25 to 40, 60, and $80^{\circ}C$, LIV characteristics of the cells were measured and the properties of saturation current densities ($J_0$) were extracted from dark current-voltage (DIV) curve. From the DIV data, effect of temperature on the performance of the solar cells with different electrical structures for the emitter was analyzed. Increasing the temperature, both emitter structures showed a slight increase in $J_{SC}$ and a rapid degradation of $V_{OC}$. FF and power conversion efficiency also decreased with the increasing temperature. The degrees of $J_{SC}$ increase and $V_{OC}$ degradation for two groups were compared and explained. Also, FF change was explained by series and shunt resistances from the LIV data. It was concluded that the degradation of solar cells shows different values at different temperatures depending on the emitter type of solar cells.

A new treatment of $LiV_3O_8$ has been proposed for improving its electrochemical behavior as a cathode material for secondary lithium batteries. Lithium trivanadate, $LiV_3O_8$, can be prepared in a finely dispersed form by dehydration of aqueous lithium trivanadate gels. The ultrasonic treatment method for Liv30s has been examined in comparison with $LiV_3O_8$ prepared by solutionmethod. The ultrasonically treated products in water were characterized by XRD (X-ray diffractometry), TGA (thermogravimetric analysis) and SEM (scanning electron microscopy). These measurements showed that the ultrasonic treatment process of aqueous $LiV_3O_8$ caused a decrease in crytallinity and considerable increased in specific surface area and interlayer spacing. The product, ultrasonically treated in water for 2 h, showed a high initial discharge capacity and was charge-discharge cycled without large capacity loss. The ultrasonic treated Liv30s can improve not only the specific capacity, but also the cycling behavior

Objective : Spinal cord injury (SCI) is a very serious health problem, usually caused by a trauma and accompanied by elevated levels of inflammation indicators. Stem cell-based therapy is promising some valuable strategies for its functional recovery. Nestin-positive progenitor and/or stem cells (SC) isolated from pancreatic islets (PI) show mesenchymal stem cell (MSC) characteristics. For this reason, we aimed to analyze the effects of rat pancreatic islet derived stem cell (rPI-SC) delivery on functional recovery, as well as the levels of inflammation factors following SCI. Methods : rPI-SCs were isolated, cultured and their MSC characteristics were determined through flow cytometry and immunofluorescence analysis. The experimental rat population was divided into three groups : 1) laminectomy & trauma, 2) laminectomy & trauma & phosphate-buffered saline (PBS), and 3) laminectomy+trauma+SCs. Green fluorescent protein (GFP) labelled rPI-SCs were transplanted into the injured rat spinal cord. Their motilities were evaluated with Basso, Beattie and Bresnahan (BBB) Score. After 4-weeks, spinal cord sections were analyzed for GFP labeled SCs and stained for vimentin, $S100{\beta}$, brain derived neurotrophic factor (BDNF), 2',3'-cyclic-nucleotide 3'-phosphodiesterase (CNPase), vascular endothelial growth factor (VEGF) and proinflammatory (interleukin [IL]-6, transforming growth factor $[TGF]-{\beta}$, macrophage inflammatory protein [MIP]-2, myeloperoxidase [MPO]) and anti-inflammatory (IL-1 receptor antagonis) factors. Results : rPI-SCs were revealed to display MSC characteristics and express neural and glial cell markers including BDNF, glial fibrillary acidic protein (GFAP), fibronectin, microtubule associated protein-2a,b (MAP2a,b), ${\beta}3$-tubulin and nestin as well as anti-inflammatory prostaglandin E2 receptor, EP3. The BBB scores showed significant motor recovery in group 3. GFP-labelled cells were localized on the injury site. In addition, decreased proinflammatory factor levels and increased intensity of anti-inflammatory factors were determined. Conclusion : Transplantation of PI-SCs might be an effective strategy to improve functional recovery following spinal cord trauma.

Objective : Carthami Flos has been used as a herb to promote blood circulation to remove blood stasis in oriental medicine for many centuries. To investigate treatment of cerebral vascular disease(CVA) by promoting blood circulation and removing blood stasis(活血化瘀法), we observed the experimental Effects of Aqua-Acupuncture of Carthami Flos on the Regional Cerebral Blood Flow and Mean Arterial Blood Pressure in Rats. Method : When aqua-acupuncture of Carthami Flos(ACF) was injected into LI4, Liv3, B23, B62, GV16, experimental effects of ACF on the regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) is not known. Therefor, this study was designed to investigate the effects of ACF on the change of cerebral hemodynamics. The changes of rCBF and MABP were tested by Laser Doppler Flowmetry(LDF). Results : When ACF was injected into LI4, change of rCBF and MABP were decreased in a injected time-dependent manner. When ACF was injected into Liv3, change of rCBF and MABP were decreased in a injected time-dependent manner. When ACF was injected into B23, change of rCBF was significantly increased in a injected time-dependent manner, MABP did not change. When ACF was injected into B62, change of rCBF was increased in a injected time-dependent manner, change of MABP was significantly decreased after injection 60min. When ACF was injected into GV16, change of rCBF and MABP were similar to the change of normal. Conclusions : In conclusion, I suggested that ACF(LI4, Liv3) has an effect that depress the blood pressure & cerebral hemodynamic acceleration and ACF(B23, B62) has an anti-ischemic effect through the improvement of crebral hemodynamics.

With the growing use of fingerprint authentication systems in recent years, the fake fingerprint detection is becoming more and more important. This paper mainly proposes a method for fake fingerprint detection based on CNN, it will visualize the distinctive part of detected fingerprint which provides a deeper insight in CNN model. After the preprocessing part using fingerprint segmentation, the pretrained CNN model is used for detecting the liveness detection. Not only a liveness detection but also feature analysis about the live fingerprint and fake fingerprint are provided after classifying which materials are used for making the fake fingerprint. Our system is evaluated on three databases in LivDet2013, which compromise almost 6500 live fingerprint images and 6000 fake fingerprint images in total. The proposed method achieves 3.1% ACE value about the liveness detection and achieves 79.58% accuracy on LiveDet2013.
