This study is a descriptive study to examine how poem causes effects of literary treatment for the contemporary people and how to improve therapeutic effect with poem by illustrating the process of therapeutic effect by poem. Each poem in the poetry book has a well-organized flow. While those poems are mixed, it can be synapsed into the cognitive system of readers by their taste in the form of introduction, development, turn, and conclusion.' The poetry book is structured with the transition of literary treatment. Such transition structure is embodied in a circle. If poetic contents are positive and creative in such transitive structure, it gives more comfort and excitement to readers increasing therapeutic effect. Therefore, it is very important to progress literatherapy narrative with such creative works.

We investigated green phosphorescent organic light-emitting diodes with stepwise doping to improve efficiency roll-off and operational lifetime by efficient distribution of triplet excitons. The host material which was 4,4,N,N'-dicarbazolebiphenyl (CBP) of bipolar characteristic that can control the carrier in emitting layer (EML). When the EML devided into four parts with different doping concentration, each devices shows various efficiency roll-off and lifetime enhancement. The distribution of the carrier and excitons in the EML can be confirmed by using stepwise doping structure. The properties of device C exhibited luminous efficiency of 51.10 cd/A, external quantum efficiency of 14.88%, respectively. Lifetime has increased 73.70% compared to the reference device.
