Korean Hurricane Media Discourse analysis

Presented within this thesis, I have analyzed a particular TV broadcast news discourse called Korean Hurricane Media Discourse (KHMD), which was presented online from YTN, a Korean cable TV news station. The data presents the topic of the Korean refugees who were forced to evacuate to Baton Rouge from New Orleans, after facing the destructions of Hurricane Katrina on August 2005. The methods are Ron Scollon’s TV news frames (1998), van Dijk’s superstructure (1988a and 1988b) and macrostructure (1980), Allan Bell’s news structure (1991), Dell Hymes’s SPEAKING model (1974), and Erving Goffman’s frameworks (1986). Since KHMD is a spoken, plannable TV news discourse along with written text presented on the Internet, chapter two discusses the relationships between spoken and written discourse, and between planned and unplanned discourse. In addition, the relationship between discourse and culture is manifested because of Korean cultural concepts in the data. Chapter three discusses media culture in Korea and the relationship between media and discourse. KHMD is analyzed by Scollon’s three frames. Chapter four shows a comparison of Bell’s with van Dijk’s news schema and macro-analysis in translation. KHMD is contextualized in terms of Dell Hymes’s SPEAKING model in chapter five. Finally, chapter six demonstrates that Goffman’s frame analysis helps to understand particular events. As a result, he provides two frameworks. Hurricane Katrina can be interpreted as a natural framework; and can also be represented as a social (cultural) framework, otherwise know as Dong-po-ae (Brotherhood), a topic presented by KHMD

Role of Irgm2 in anti-Toxoplasma immunity

Interferon-inducible GTPases, such as immunity-related GTPases (IRGs) and guanylate-binding proteins (GBPs), are essential for cell-autonomous immunity against a wide variety of intracellular pathogens including Toxoplasma. IRGs comprise regulatory and effector subfamily proteins. Regulatory IRGs Irgm1 and Irgm3 play important roles in anti-Toxoplasma immunity by globally controlling effector IRGs and GBPs. There is a remaining regulatory IRG, called Irgm2, which highly accumulates on parasitophorous vacuole membranes (PVMs). Very little is known about the mechanism of the unique localization on Toxoplasma PVMs. Here, we show that Irgm2 is important to control parasite killing through recruitment of Gbp1 and Irgb6, which does not require Irgm2 localization at Toxoplasma PVMs. Ubiquitination of Irgm2 in the cytosol, but not at the PVM, is also important for parasite killing through recruitment of Gbp1 to the PVM. Conversely, PVM ubiquitination and p62/Sqstm1 loading at later time points post-Toxoplasma infection require Irgm2 localization at the PVM. Irgm2-deficient mice are highly susceptible to Toxoplasma infection. Taken together, these data indicate that Irgm2 selectively controls accumulation of anti-Toxoplasma effectors to the vacuole in a manner dependent or independent on Irgm2 localization at the Toxoplasma PVM, which mediates parasite killing

Adaptive Segmentation and Stitching on 8K UHD Video

Transmission technology is necessary to display contents stored on the Cloud server. When excessive compression is performed to the transmission of ultra-high resolution image, tangibility is reduced. Therefore, in this paper, we proposed an algorithm that divides the image into a number of sub-images. The sub-images were restored to the original one by stitching at the receiver. In the existing study, important objects were located at the center of the images, but an exception occurred when they are at the edge of the images. The saliency map was used to detect their main part so that the region of interest will not be divided. The images were divided depending on the position of saliency map. It is expected that users will be able to provide realistic signage by displaying ultra-high resolution images with a large screen
