The purpose of this study is to examine how the Hanbok is expressed in the ballet performances through the 'La, Chun-hyang', a classic Korean ballet. 'La, Chun-hyang', was performed from 2009 and 2010, but there were some differences in choreography by the director's intention. According to these changes, the methods of expression of ballet objects were changed as well. Therefore, totally different personalities were shown despite the fact that theses were same performances. Every costume objects in dance performances like the ballet can be used to express the story and the characters. Moreover, the object designs of Hanbok portray creativity and originality that simultaneously refers to history. In order for stage costume objects to popularize, the making method and process have to be developed like the objects of the Hanbok that signified historicity.

For the commercialization of all-solid-state batteries, it is essential to develop a solid electrolyte that can be operable at room temperature, and it is necessary to manufacture all-solid-state batteries by adopting materials with high ionic conductivity. Therefore, in order to increase the ionic conductivity of the existing oxide-based solid, Li₇La₃Zr₂O₁₂ (LLZO) doped with heterogeneous elements was used as a filler material (Al and Nb-LLZO). An electrolyte with garnet-type inorganic filler doped was prepared. The binary metal element and the polymer mixture of poly(ethylene oxide)/poly(propylene carbonate) (PEO/PPC) (1:1) are uniformly manufactured at a ratio of 1:2.4, The electrochemical performance was tested at room temperature and 60 ℃ to verify room temperature operability of the all-solid-state battery. The prepared composite electrolyte shows improved ionic conductivity derived from co-doping of the binary elements, and the PPC helps to improve the ionic conductivity, thereby increasing the capacity of all-solid-state batteries at room temperature as well as 60 ℃. It was confirmed that the capacity retention rate was improved.

In previous study, we investigated the mechanism of suppression of inducible nitric oxide synthase (iNOS) and cyclo-oxygenase-2 (COX-2) by ergolide, sesquiterpene lactone from Inula Britannica. In this study, the suppression of iNOS and COX-2 by ergolide might be attributed to selective inhibition of NF-$\_$K/B signaling pathways. Here, we investigated the suppressionmechanism of NF-$\_$K/B signaling pathways by ergolide in TPA-stimulated HeLa cells. (omitted)
