  • Despite many researches related with in-vitro culture of porcine spematogonial stem cells (SSCs), adherent culture system widely used has shown a limitation in the maintenance of porcine SSC self-renewal. Therefore, in order to overcome this obstacle, suspension culture, which is known to have numerous advantage over adherent culture, was applied to the culture of porcine SSCs. Porcine SSCs retrieved from neonatal testes were suspension-cultured for 5 days or 20 days, and characteristics of suspension-cultured porcine SSCs including proliferation, alkaline phosphatase (AP) activity, and self-renewal-specific gene expression were investigated and compared with those of adherent-cultured porcine SSCs. As the results, the suspension-cultured porcine SSCs showed entirely non-proliferative and significantly higher rate of AP-positive cells and expression of self-renewal-specific genes than the adherent-cultured porcine SSCs. In addition, long-term culture of porcine SSCs in suspension condition induced significant decrease in the yield of AP staining-positive cells on post-day 10 of culture. These results showed that suspension culture was inappropriate to culture porcine SSCs, because the culture of porcine SSCs in suspension condition didn't stimulate proliferation and maintain AP activity of porcine SSCs, regardless of culture periods.

  • The purpose of this study is to examine the different communication messages behind African women's hairstyles, and to compare young and old African women's hairstyles. The contents of this research are: the hairstyle as communication media, the types of African women's hairstyles, and the difference between young and old women's hairstyles. We used a review of literature and an empirical study as the research methods for this study. For the literature review, we used papers on African hairstyles, and we linked hairstyles to corresponding communication. For the empirical study, we took a database of 240 pictures (120 pictures of young women and 120 pictures of old women) from websites related to African hairstyles and we analyzed the pictures to differentiate between young and old African women's hairstyles. The results of this study reveal that African women's hairstyles express messages of power, ceremony, and status and identification communication. Within the 240 pictures, we found out which hairstyles are preferred by young and old women. Young African women prefer long, straight hairstyles and artificial hair (wigs), while old women keep short, natural hairstyles. The result of this research will be useful for understanding African women's hairstyles as well as contribute to the field of hair design.

  • In order to protect fungal diseases, leaf disc explants of Solanum tuberosum cultivar, Belchip, was infected with an Agrobacterium MP90 strain containing chimeric gene construct, consisting of antibiotic resistance and chitinase gene driven by the CaMV 35S promoter, for transformation. Regenerated multiple shoots were selected on a medium containing kanamycin and carbenicillin after exposure to Agrobacterium. The presence and integration of the npt II and chitinase gene were confirmed by polymerase chain reaction(PCR). Northern blot analysis indicated that the genes coding for the enzyme could be expressed in potato plants. The chitinase activity of transgenic potato plants was higher than the control potato.

  • The Bible has been and still is one of the most influential books ever published. The English Bible has a great impact on English language, literature, and culture. Therefore, knowledge of the Bible is essential in learning English language, its literature, culture and tradition. Biblical allusions are found in great literature and the daily newspapers as well. Rock musicians, screenwriters, television producers, and advertisers use the Bible as a source. Politicians use the words and accounts of the Bible to frame their debates. The Bible has continued to be philosophically, ethically, religiously, and politically influential in Western, Eastern, now World cultures. Therefore, not to know it means not to understand a great portion of world culture. This study examines the influence of the first book of the Bible, Genesis, in English language, literature, and culture. Furthermore, this study suggests why we should incorporate the English Bible in English education.
