With the development of new ICT technology, smart keys for vehicles are terminals with ICT technology. Therefore, when the vehicle and the smart key communicate with RF, a cyber hacking attack is possible. Cyber-attacks on smart keys can pose a threat to vehicle theft and vehicle control. Therefore, it is necessary to study hacking attacks and vulnerabilities of smart keys for autonomous vehicles. In this paper, we analyze the cyber attack case of RF communication for vehicles and smart keys. In addition, a real RF cyber attack on the smart key is performed, and the vulnerability of radio wave replication in the same frequency band is found. In this paper, we analyze the vulnerability of RF communication between vehicles and smart keys, and propose a countermeasure against cyber security. In the future, plans to strengthen cyber attacks and security through the popularization of autonomous vehicles will become basic data to protect human and vehicle safety.

Construction is one of the oldest fields of providing human living comfort. However, despite the continuous development not only in IT but also in other fields, productivity degradation due to low automation is still serious. In particular, the use of the 4th industrial revolution technologies in construction is just beginning. Blockchain, which is one of the 4th industrial revolution technologies, is a type of a distributed database that is used to replicate, share, and synchronize data spread across different geographical locations, such as multiple sites, countries, or organizations. In this paper, we introduce the block chain and analyze use cases according to seven themes in construction. As a result of the analysis, it is expected to increase the understanding of blockchain in construction and provide usefulness for the development of various services in the future.

Recent advances in new media for sensory experiences keep expanding visual expression methods in installation art such as projection mapping and virtual reality. Artists can create and develop visual expression techniques based on such new media. Projection mapping is a new medium that continues to add various possibilities to visual expression in media art. Under the projection mapping environment, artists can recompose the object or space with the digital content by projecting video onto three-dimensional surfaces in the space. This paper focuses on the process where visual expression with the projection mapping technology leads to viewers' sensory experience. To this end, "reproducibility," "dissemination," "virtuality," and "interactivity" of media were analyzed to describe the meaning and *definition of visual expression. Artworks are considered as an example to study visual expression techniques such as "repetition and overlap," "simulacrum and metaphor," and "displacement and conversion." I applied the analysis and created Domino, a projection mapping artwork, which helps the research on visual expression techniques that can lead to sensory experience the extensibility of visual expression.

ESRRB (Estrogen related receptor $\beta$) is an orphan receptor, and have a role on maintaining the undifferentiated state and self-renewal of pluripotent stem cell as a transcription factor which regulates the expression of OCT4 and NANOG genes. Also, Feng et al. (2009) reported that Esrrb, Oct4 and Sox2 could induce pluripotent stem cell from somatic cells. The aim of the present study was to develop the direct delivery system of human ESRRB protein into human amniotic fluid-derived stem cells (AFSCs) and to analyze the effect of ESRRB on the regulation of pluripotency-related genes. Human ESRRB has three isoforms arisen by alternative splicing. We cloned short-form ESRRB and made a fusion protein of ESRRB and R7 for an efficient protein transfer to cell. R7 as cell-penetrating peptide(CPP) can help to transfer ESRRB into cells. R7-ESRRB-His6 protein was observed in the cytoplasm and nuclei within 5 hours after treatment. Also, we could observe R7-ESRRB-His6 protein only in the nuclei within 24 hours. Realtime PCR showed that ESRRB increased expression of OCT4 and NANOG as well as SOX2 gene. Therefore, we demonstrated that R7-ESRRB-His6 proteins were efficiently transferred into the nuclei of AFSCs and work well as a possible transcription factor.

Rice is one of the most important crop in the world, in particular for food resources. With its small genome size of 383 Mb, the Oryza sativa is a model plant for genome research. Indeed, it's grain provides human with a source of carbohydrates and proteins. Rice grain has relatively low protein contents (around 8%) compared to other legume seeds (around 40%). Osborne classified seed proteins into water soluble albumin, salt soluble globulin, alcohol soluble prolamin and acidic/alkaline solution soluble glutelin. Glutelin and prolamin are the major storage proteins in rice. For the gene expression study of seed storage proteins, we analyzed 33,192 EST clones at immature stages in a rice cultivar (Oryza sativa L. cv. 'Ilpum'). Based on the expression analysis, we cloned 11 glutelin genes and figured out the 8 genes are located on Chromosome 2. The expression of glutelin genes appears to be about 28.2% of total level in immature seeds. Interestingly, glu-04 is duplicated as inverted sequences on the same chromosomes as far 4.5 kb. Our results indicate that glutelin genes, evolutionarily, were replicated on the chromosome and thus expressed as specific manners. In a whole protein composition analysis, glu05 (type B7) contains the highest lysin contents (4.51%) among the 11 rice glutelin genes. It will be an interesting future work to increase lysin contents by the gene overexpressor strategy with the aim of improved diet nutritionally fortified.

The issues on the representation of digital images, the uncanny is not considered aesthetically but must be overcome. It seems that the future of visual media using digital images, depends on the development and advancement of the digital technology. However, the Brothers Quay regarded as unique and experimental animators, focus their attention towards the past rather than the future. They trace back to the origin of the media, reproducing, manipulating, and representing gestures in oder to restore the shock and thrill delivered in film and animation. The Brothers Quay explore the uncanny of gestures through the mechanism of medium. They work in a wide range of genres, from animation, live action to dance film. The creaking spasms, which create the feeling that the movement does not belong to this world, and the strange gestures, reveals the flicker of the still projection and make audiences recognize gestures in the true meaning of the word. While they animate live actors and dead objects like automata, the hidden desires are revealed over screen. In this paper, focusing on the works of Brothers Quay, I tried to explore the uncanny of gesture based on Freud's and Jentsch' theory of uncanny.

To investigate the biological activity of recombinant human granulocyte colony-stimulating factor (rec-hG-CSF) in mammalian cells, hG-CSF gene was cloned using the eDNA extracted from the human squamous carcinoma cell lines and rec-hG-CSF was produced in CHO cell lines. To analyze the biological activity in vivo, the rec-hG-CSF protein was injected into mice subcutaneously on days 0 and 2. Blood was withdrawn for white blood cell (WBC) determination 5 days after the first injection. WBC values were found to have increased significantly. A pEGFP-mUII-hG-CSF vector was transfected into somatic cell lines isolated from bovine fetal cells. The colony expressing EGFP signals was observed with a confocal microscope. These data suggest that the rec-hG-CSF produced in this study has potent activity in vivo. Thus, the results of this biological activity show that rec-hG-CSF can be enhanced considerably by genetic engineering that affects potential activity, including mutations, which add the oligosaccharide chain and construct double-fusion proteins. A pEGFP-mUII-hG-CSF vector can be utilized for the production of cloned transgenic livestock.

As data can be permanently stored and freely distributed, in modern society, the Internet became a world that remembers everything forever. Because of that, there has been increasing the number of accident with never-forgetting data and, as a result, a movement has been emerged to apply a notion of 'oblivion' to internet world. The movement is called 'The right to be forgotten.' However, 'The right to be forgotten' in a higher level which internet users want to be guaranteed is very limited in the juridical approach because of the confliction with the other basic rights and problems. On the other hand, the requests of individuals to guarantee 'The right to be forgotten' has been urged digital extinction technology, such as volatile SNS, Digital Aging System, to be developed. With introduction of oblivion, digital extinction technology with setting expire date on digital information can present a new solution on assuring 'The right to be forgotten.' This research establishes the detail scope of, analyzes the level of assurance of, and, through digital extinction technology with the established scope, suggest the potential assurance of the 'The right to be forgotten'.

Salmonella is an important food-and water-borne pathogen associated with acute gastrointestinal illnesses around the world. The most common serotypes isolated from humans are Salmonella enterica serotype Typhimurium (S. Typhimurium) and S. Enteritidis. Traditional detection methods for Salmonella are based on cultures using selective media and characterization of suspicious colonies by biochemical and serological tests. These methods are generally time-consuming and not so highly sensitive. Recently, the Loop Mediated Isothermal Amplification and real-time PCR has been used as a highly sensitive, specific, and rapid test for the presence of pathogenic bacteria. In this study, a LAMP and real-time PCR was used to detect S. Typhimurium and S. Enteritidis. We selected target genes, which were the in invA and a randomly cloned sequence specific for the genus Salmonella. With LAMP and real-time PCR, random sequence was detected from Salmonella spp, invA were detected from all strain of S. Typhimurium and S. Enteritidis. This assay indicate that the specificity, sensitivity and rapid of the LAMP and real-time PCR make them potentially valuable tools for detection of S. Typhimurium and S. Enteritidis.
