Calcium plays a vital role as a second messenger in many signaling pathways in plants. The calcineurin B-like proteins （CBLs） represent a family of plant calcium-binding proteins that function in calcium signaling by interacting with their interacting protein kinases （CIPKs）. In our previous study, we have reported a role for one of the CBLs （CBL9） and one of the CIPKs （CIPK3） in ABA signaling. Here, we have shown that CBL9 and CIPK3 physically and functionally interact with each other in regulating the ABA responses. The CBL9 and CIPK3 proteins interacted with each other in the yeast two- hybrid system and when expressed in plant cells. The double mutant cbl9cipk3 showed the similar hypersensitive response to ABA as observed in single mutants （cbl9 or cipk3）. The constitutively active form of CIPK3 genetically complemented the cbl9 mutant, indicating that CIPK3 function downstream of CBL9. Based on these findings, we conclude that CBL9 and CIPK3 act together in the same pathway for regulating ABA responses.

Aqueous ammonia （NH3） solution can be used as an alternative absorption for the control of CO2 emitted from flue gases due to its high absorption capacity, fast absorption rate and low corrosion problem. The emission of CO2 from iron and steel plants requires much attention, as they are higher than those emitted from power plants at a single point source. In the present work, low concentration ammonia liquor, 9 wt.%, was used with various additives to obtain the kinetic properties using the blast furnace gas model. Although a solution with a high ammonia concentration enables high CO2 absorption efficiency, ammonium ions are lost as ammonia vapor, resulting in reduced CO2 absorption due to the lower concentration of the ammonia absorbent. To decrease the vaporization of ammonia, ethylene glycol, glycerol and glycine, which contain more than one hydroxyl radical, were chosen. The experiments were conducted at 313 K similar to the CO2 absorption conditions for the blast furnace gas model.

In the medical field, there are growing interests in applied research such as in vivo fluorescence monitoring because of excellent body transmission characteristic of the near-infrared light. However, optical noise by excitation light and illumination equipment for medical applications such as interior light, surgical light decrease efficiency of the fluorescent signal when observers such as surgeons confirm fluorescence signals in medical field. To solve these problems in medical field, we have analyzed external noise factors by effect on image realization, quantification of optical noise generation by external factors, and have suggested methods of minimize the optical noise in this paper. In case of fluorescence imaging in the operating room, it has been confirmed that fluorescent excitation light, interior light and surgical light are factors to generate optical noise. To acquire near-infrared fluorescence images and to compare fluorescence contrast under conditions of darkroom, interior light and surgical light, light emitting diodes (LEDs) sources that have peak wavelength at 740, 760 and 780 nm respectively were used as excitation light sources. In addition, short-pass filter which has transmission edge at 775 nm has been applied to minimize the optical noise in each external noise factor. By comparing contrast of each image before and after use of the short-pass filter, we confirmed that optical noise reduced 49%, 56% and 66% in external noise factors respectively.
