We propose one- and two-dimensional reference functions for processing of integral/multiview imaging. The functions provide the synthesis/analysis of the integral image by distance, as an alternative to the composition/decomposition by view images (directions). The synthesized image was observed experimentally. In analysis confirmed by simulation in a qualitative sense, the distance was obtained by convolution of the integral image with the reference functions.

Parachlorella sp. is an efficient fatty acid producer that can be used in the production of biofuels, feeds, and fertilizers. Microalgae show varying responses to culture conditions, even those within the same species. In this study, growth and fatty acid composition of a newly isolated Parachlorella sp. from the Nakdong river of Korea in different culture media were investigated. The microalga was cultivated in 400 ml bubble column photobioreactors using BG-11, BBM, TAP, and modified TAP (MTAP) media. It was shown that using BBM led to greater fatty acid accumulation (34%), while using TAP medium led to greater biomass productivity (0.34 g/l/day). Composition of the TAP medium was modified to have the N:P ratio of BBM while also varying concentrations of N and P to improve fatty acid productivity. One of the modified TAP media, MTAP-1 (104.8 mgN/l, 135.2 mgP/l, N:P ratio = 0.77), showed the highest fatty acid concentration of 0.69 ± 0.04 g/l, while those from TAP and BBM were 0.48 ± 0.06 g/l and 0.40 ± 0.02 g/l, respectively. The results showed that microalgal fatty acid productivity could be enhanced by changing the N:P ratio and concentrations.

This study is based on the screen composition(shot size, split screen, candidate placement, lighting, stage) that fits the discussion process (round table, sitting, standing method) adopted from the 19th presidential candidates' TV joint discussion to analyze the adequacy and limitations of the methodology(design, candidate background, etc.). In addition, the progress and screen composition of the 45th US Presidential Candidates Debate in 2016 and the 25th Presidential Candidates of France TV Joint Debate in 2017 have been analyzed to compare and contrast the methods used in Korea. Through this, we apply the screening method to the 20th Presidential Candidate TV Joint Debate, which will be held in 2022, to fit the fixed discussion process that can fully identify candidates' qualities, policies, and vision.

Mammalian cell cultures have been used extensively to produce proteins for therapeutic agent because of their ability to perform post-translational modification including glycosylation. To produce recombinant protein, many factors and parameter are considered such as media composition, host cell type, and culture process. In this study, recombinant human erythropoietin (rhEPO) producing cell line was established by using glutamine synthetase system. To reduce serum concentration in media, we compared direct adaptation with step adaptation. Cell growth was faster in step adaptation. In low-level serum media, there were insufficient glucose for cell growth. Thus, we added glucose in low-level serum media from 2 g/L to 4.5 g/L. Titer of rhEPO was higher than other conditions at 4.5 g/L of glucose. Additionally, N-methyl-D-aspartate (NMDA), 13-cis-retinal, and pluronic F-68 (PF-68) were added to enhance productivity in CHO cell cultures. In conclusion, we applied CHO cell producing rhEPO to low-level of serum in media using step-adaptation. Also, we confirmed positive effect of NMDA, 13-cis-retinal, and PF-68.

This study examines the influence of experiencing interactive media in exhibition halls on the satisfaction and perception for the exhibition space. Field measurements and surveys were performed in two exhibition halls where various interactive media were exhibited. Results imply that experiencing interactive media was important to enhance understanding the information provided by them. In order to improve satisfaction for the exhibition halls, the layout of space need to be organized effectively in a way that visitors easily feel interest in the contents and information exhibited in the space. Also, in order to keep better perception for exhibition space, the information provided in the space should be organized clearly and open to visitors easily. The flow of visitors' traffic in the exhibition space should be perceived easily by the visitors. Multiple linear regression indicated that the space should be organized effectively with good visual composition that surrounds the exhibits in order to improve satisfaction level for the exhibition hall. In addition, various information provided by the media contributed to improve perception for the exhibition hall.

In the contemporary age, social environment has changed from analog to digital. As a media is developed, the public is more familiar to digital than analog. In this society, media art rises as new art. One of the most useful methods in the media art is projection mapping. In this paper, I propose a realization process of artwork 'Cloned Me' that is realized by projection mapping method. Artwork is formed by projecting image contents that are visualized a music on a steel structure. It is different from media facade that the object projected contents has a story composition. It is a strength that the object and contents are connected by story and composition. Also it can be modified each other easily for harmony because the structure is assembly-type. A face that is projected by beam projection is consist of unique structure not fixed rectangular frame. Artwork 'Cloned Me' has significance that it reflects the present age to develop digital cloning.

Influence of vitamins on the felt and lipid production of Aspergilus niger var. macrosporus, Aspergillus fumigatus and penicillium notatum were investigated after 10 days of incubation at $30^{\circ}C$ under static culture condition. The felt of molds were lower in the media containing vitamins than control medium. The lipids produced by each strains were highest yields in media containing vitamins. Among of these Aspergillus niger var. macrosporus and Aspergillus fumigatus produced. 4.6g and 5.28g in medium containing inositol 2.5mg/l and 0.5mg/l, respectively; while Penicillium notatum produced 1.51g in a medium containing thiamine 10mg/l. The major fatty acid of lipids were palmitic acid, stearic acid, oleic acid and linoleic acid. Aspergillus niger var. macrosporus was lower palmitic acid in media containing vitamins than control medium, While linoleic acid was higher in media containing thiamine and inositol. Aspergillus fumigatus was lower oleic acid in media containing vitamins than control medium, While linoleic acid was higher in media containing vitamins. Peniillium notatum was lower palmitic acid, oleic acid and stearic acid in media containing vitamins but linoleic acid was higher. The composition of fatty acid of lipids changed depending on the media containing vitamins but hardly found a certain tendency except linoleic acid which was higher in a media containing thiamines and inositols. The degree of unsaturation of fatty acids in the lipids were comparatively higher in media containing vitamins than control medium.
