The purpose of this paper is to clarify the life and poetry of Dokshok Hwang Hyok. In Chapter 2, we looked at the life of Hwang Hyok. There are two characteristics in the life of Hwang Hyok. First, Hwang Hyok had excellent literary talent. Secondly, Hwang Hyok wrote in an attempt to surrender during the Japanese Invasion of Japan. That is why he lived a 21 year detained life. In Chapter 3, we looked at poetry based on the life of Hwang Hyok. The features of poetry are as follows. First, the image of Somu and reality of Tiger and Dhole go around. Hwang Hyok lived a confined life because of the Japanese Invasion of Korea. Because of that, Hwang Hyok recognized the Japanese invasion of the Imperial Japan as a world where Dhole and tigers travel around. It symbolized the image of Sommu that he did not surrender. Second, Changsha, is the world and Gulwon images. Changsha is Gulwon the space of self-destruction. Hwang Hyok likened his dark life to Gulwon dead. This is because Hwang Hyok's life is similar to Gulwon's life. In other words, Hwang Hyok was most appropriate to compare his tough life to Gulwon, who drowned in Myeoglasu.

A pregnancy diagnosis is an important standard for control of livestock's reproduction in paricular dairy cattle. High reproductive performance in dairy animals is a essential condition to realize of high life-time production. Pregnancy diagnosis is crucial to shortening the calving interval by enabling the farmer to identify open animals so as to treat or re-breed them at the earliest opportunity. MicroRNAs are short RNA molecules which are critically involved in regulating gene expression during both health and disease. This study is sought to establish the feasible of circulating miRNAs as biomarkers of early pregnancy in cattle. We applied Illumina small-RNA sequencing to profile miRNAs in plasma samples collected from 12 non-pregnant cows ("open" cows: samples were collected before insemination (non-pregnant state) and after pregnancy check at the indicated time points) on weeks 0, 4, 8, 12 and 16. Using small RNA sequencing we identified a total of 115 miRNAs that were differentially expressed weeks 16 relative to non-pregnancy ("open" cows). Weeks 8, 12 and 16 of pregnancy commonly showed a distinct increase in circulating levels of miR-221 and miR-320a. Through genome-wide analyses we have successfully profiled plasma miRNA populations associated with pregnancy in cattle. Their application in the field of reproductive biology has opened up opportunities for research communities to look for pregnancy biomarker molecules in dairy cattle.
