Zainichi Koreans and the Jeju 4.3 Incident: Focusing on Soup and Ideology
Aya Narikawa 건국대학교 아시아·디아스포라 연구소 2022 International Journal of Diaspora&Cultural Critici Vol.12 No.1
Director Yang Yong-hee, a Zainichi Korean who has portrayed the relationship between her family and North Korea in films such as Dear Pyongyang (2005) and Our Homeland (2012), released a new 2021 documentary, Soup and Ideology, regarding her mother and the Jeju 4.3 incident. The novels of Kim Sok-pom, who too is a Zainichi Korean, including “The Death of the Crow” and “Volcano Island,” were what publicised the Jeju 4.3 incident in Japan. Although Kim Sok-pom himself was born in Osaka and did not directly experience the incident, he said he was shocked by the stories he heard from stowaways from Jeju Island, which inspired him to write the novels. It is only in recent years that Yang Yong-hee’s mother has spoken about her experience of it. The films Pacchigi! LOVE & PEACE (2007) and Barbecue Dragon (2018) also portray or refer to the Jeju 4.3 incident. Both films have a Zainichi Korean director or producer, who have incorporated their own father’s story into the film. Focusing on Yang Yong-hee’s Soup and Ideology, which narrates her mother’s story, I would like to examine what the Zainichi Korean directors and producers have tried to convey by using the incident as the basis of their films.
Implementation of Schnorr Signcryption Algorithm on DSP

The lack of data security in public mobile telecommunication system increases the need for a strong data protection and security mechanisms. Cryptography is considered as one of the key elements that provides security for mobile systems. Signcryption algorithm, which is based on public key cryptography, provides both confidentiality and authenticity in one step. Moreover, hardware implementations of cryptographic algorithms provide scalable solutions to enhance the level of security of the existing hardware. In this paper, we present a case study on using a DSP board to construct a secure communication channel. We use the constructed DSP board as a hardware cryptosystem to increase the security of transmitted data using any mobile communication system. We evaluate the performance by computing the consumed time by encryption/decryption process, while implementing the Schnorr Signcryption scheme on a DSP. Furtheremore, we propose an enhanced model of applying multiple DSP using pipelines and parallelization technique to decrease the consumed time in the whole process.

The double-layered Ti/Si barrier metal is demonstrated for the source/drain Cu interconnections in oxide semiconductor thin-film transistors (TFTs). The transmission electromicroscopy and ion mass spectroscopy analyses revealed that the doublelayered barrier structure suppresses the interfacial reaction and the interdiffusion at the interface after thermal annealing at 350◦C. The underlying Si layer was found to be very useful for the etch stopper during wet etching for the Cu/Ti layers. The oxide TFTs with a double-layered Ti/Si barrier metal possess excellent TFT characteristics. It is concluded that the present barrier structure facilitates the back-channel-etch-type TFT process in the mass production line, where the four- or five-mask process is used.

In this study, solvent casting technique was employed in fabricating ocular inserts using Pullulan as a natural film forming agent and Hydroxy propyl methyl cellulose as a synthetic film forming agent. Ciprofloxacin hydrochloride—an effective ocular antibiotic- was employed as a model drug in this study. Further modification of ciprofloxacin release from the ocuserts is obtained via coating the dual sides of the ocuserts by hydroxy ethyl cellulose as release controlling membrane. The prepared ocuserts were evaluated for various physiochemical parameters, and the in-vitro release pattern. Furthermore, accelerated stability test, sterility test, microbiological studies as well as eye irritancy test were appraised for a selected formula. All the developed ocular inserts showed that as the rate controlling membrane increased in percentage, the thickness and weight of sealed ocuserts increased. The drug content varied between 85.4 ± 16.5–98.2 ± 27.4% and the drug release followed zero-order pattern. The selected formula showed the highest sustainment effect indicated by the least release rate (16.3%/h) containing pullulan (2.0%) and dual coat of hydroxy ethyl cellulose (6.0%). Pullulan based ocular insert remained stable and intact at accelerated conditions for 30 days with overall degradation of the drug less than 2.5%. Non-irritant response in rabbits with primary irritation indices score 0 on Peyman Scale and excellent microbiological activity represented by a greater zone of inhibition (5.6 cm) compared to an ocuserts with no drug (0.8 cm) against Staphylococcus aureus. This study showed the suitability of dual sided coated Pullulan ocusert in attaining the desired sustainment effect with excellent stability.
