The goal of this study was to verify the phylogenetic status of the Korean native goats (KNG). We determined the complete sequence of the mitochondrial cytochrome b gene in 48 goats among four populations. We also analyzed genetic variability within goats, and a phylogenetic analysis was performed by comparison with other country's goats. Three nucleotide substitutions were detected, and two of these were missense mutations that occurred due to a substitution of amino acid. Four haplotypes were defined from KNG. Three of these haplotypes were only found in the Chinese goat. However, the other haplotype was KNG-specific. In the phylogenetic analysis, four clades (A~D) were classified among domestic goats, and the KNG was classified into clade 1 that estimated as lineage A based on the D-loop sequence. Each haplotype from the KNG was clustered closely with that of the Chinese goat. The results of haplotype distribution and phylogenetic location suggest that strong gene flow occurred from China to the Korean Peninsula.

This study analysed the narrative strategies in TV drama utilized in order to support the recent feminism movements. The analysis revealed that this TV drama breaks away from the clichéd patriarchal drama series. It portrays the main characters are not the sons but the two daughters-in-law, and represents the women challenging the order of the patriarchy, and resolving the issues. In this drama, men's power was removed and female agents were held up to ridicule. In addition, it eradicates the traditional female conflict structures and creates a strong bond between the females. With this storyline, TV series concludes with two achievements. One, the stepmother and the mother co-parent the child instead of the father, suggests that a non-blood related matriarchal family is possible. Two, the heir to the chaebol family, which is traditionally a patrilineal structure, is not the oldest son or the immoral son, but the lesbian daughter-in-law, overturning the idea of heteronormativity that is dominant in the patriarchal system.

In an effort to gain greater understanding of the maternal lineages of the Jeju native pig (JNP), we analyzed the mitochondrial DNA (mtDNA) CYTB gene and compared it with those of other pig breeds. PCR-RFLP analysis was conducted with six pig breeds including JNP, and then the RFLP patterns allowed for the separation of the pig breeds into two distinct haplotypes (mtCYTB1 and mtCYTB2). The JNP CYTB sequences were detected in both the European and Asian breed clusters on the phylogenetic tree. The J2 group was sorted with the indigenous cluster of Asian pig lineages and was related closely to Chinese native pig breeds, but a second group, J1, was sorted with the European pig lineages and appeared to be related to Spanish Iberian native pigs, rather than to Asian breeds. These results indicate that the JNP currently raised on Jeju Island have two major maternal origins estimated in Asian and European pigs. We concluded that the JNP that share a common lineage with indigenous Asian pigs were domesticated in the distant past, originating from pigs that were already being raised elsewhere at that time, and that the European pig breeds introduced in the twentieth century have also contributed to the formation of this pig population.

Korean native goats, which are characterized by black coat color, have existed on the Korean peninsula for a long time. Until now, there has been no comprehensive investigation concerning their genetic diversity, phylogenetic analysis or origin. In this study, we investigated the genetic diversity and verified phylogenetic status of the Korean native goat using the 453-bp fragment of the hypervariable fragment I (HVI) of mitochondrial DNA (mtDNA) D-loop region from 60 individuals among 5 populations. The Korean native goat showed less haplotype diversity when compared with goats from other countries. In addition, 6 haplotypes that had not been previously reported were verified in this study. In phylogenetic analyses with other country's goats, 10 haplotypes from Korean native goats were classified into mtDNA lineage A. Moreover, in a phylogenetic tree for goats which contained mtDNA lineage A, 8 of 10 haplotypes could be included in a subgroup with goats from Vietnam and an area of China. However, none of the remaining haplotypes belonged to a major group of Korean native goats and were located on different independent positions. These results suggest that almost Korean native goats aligned more closely to China and Vietnam breeds in mtDNA lineage A and there was no gene flow from other mtDNA lineages. Our results will contribute to conservation strategies and genetic breeding of Korean native goats.
