In the field of animation, as technology advances, production technology, production methods, and production culture are also steadily developing. The demand for content is increasing rapidly around the OTT platform, and the demand for animation content and diversity is increasing. With these market changes, animation creation ability is becoming a more important animation education goal. There is also a need to innovate educational methods to provide students with the skills and knowledge required in the modern animation business. This paper investigated the composition of the educational curriculum of domestic and foreign animation universities education. It examines artificial intelligence (AI) technology that can be used in animation creation and explores the design and direction of the university animation curriculum using it. AI technology has already proven its potential in various areas, and it is integrated into the animation curriculum to present various development potentials. Using AI technology, students can focus on practical and essential animation education by preventing technical difficulties in animation creation, increase their experience in animation production, and experiment with planning and producing various contents. It is proposed to design an educational curriculum that further strengthens animation creation and production capabilities by forming smart animation classes to foster talents who can lead the future animation industry in a new direction.

Recently, 3D displays are supplied in the 3D markets so that the demand for 3D stereoscopic contents increases. In general, a simple method is to use a stereoscopic camera. As well, the production of 3D from 2D materials is regarded as an important technology. Such conversion works have gained much interest in the field of 3D converting. However, the stereoscopic image generation from a single 2D image is limited to simple 2D to 3D conversion so that the better realistic perception is difficult to deliver to the users. This paper presents a new stereoscopic content production method where foreground objects undergo alive action events. Further stereoscopic animation is viewed on 3D displays. Given a 2D image, the production is composed of background image generation, foreground object extraction, object/background depth maps and stereoscopic image generation The alive objects are made using the geometric transformation (e.g., translation, rotation, scaling, etc). The proposed method is performed on a Korean traditional painting, Danopungjung as well as Pixar's Up. The animated video showed that through the utilization of simple object transformations, more realistic perception can be delivered to the viewers.

The objective of this study was to determine the effect of palm and/or linseed oil (LSO) supplementation on carcass quality, sensory evaluation and fatty acid profile of beef from crossbred Wagyu beef steers. Twenty four fattening Wagyu crossbred beef steers (50% Wagyu), averaging $640{\pm}18kg$ live weight (LW) and approximately 30 mo old, were stratified and randomly assigned in completely randomized design into 3 treatment groups. All steers were fed approximately 7 kg/d of 14% crude protein concentrate with ad libitum rice straw and had free access to clean water and were individually housed in a free-stall unit. The treatments were i) control concentrate plus 200 g/d of palm oil; ii) control concentrate plus 100 g/d of palm oil and 100 g/d of LSO, iii) control concentrate plus 200 g/d of LSO. This present study demonstrated that supplementation of LSO rich in C18:3n-3 did not influence feed intakes, LW changes, carcass and muscle characteristics, sensory and physical properties. LSO increased C18:3n-3, C22:6n-3, and n-3 polyunsaturated fatty acids (PUFA), however, it decreased C18:1t-11, C18:2n-6, cis-9, trans-11, and trans-10,cis-12 conjugated linoleic acids, n-6 PUFA and n-6:n-3 ratio in Longissimus dorsi and Semimembranosus muscles.

In this paper, based on the production technology and infrastructure of local cultural contents, it is determined that reconstruction and commercialization of local culture resources are necessary due to absence of character brand products centered on storytelling. It is expected to contribute to the expansion of the supply of advanced ceramic products along with the foundation of various contents production as it becomes the foundation to establish the developed business base through the differentiation strategy of the character product development based on the storytelling. In addition, due to the manual production, only a small amount of production can be produced and the production period is lengthened. On the other hand, the production period of gypsum mold is shortened by making mock-up through 3D program and 3D printing, It was effective in developing a wide variety of pottery products.

Recently, the interest of 3D contents are increased and viewers demand a variety of 3D contents. In such circumstances, underwater 3D contents are an alternative to meet the demands of viewers. Cause that underwater mass density is 1.33 times that in air the objects in underwater is bigger and closer in real. Therefore it needs to modify the distance between cameras, the distance to objects and the convergence value. In this paper, we present the method to set optimal depth values with the particularities of underwater space. In addition, through the case of underwater 3D production we present the method of underwater 3D contents development. We expect that a lot of material with colorful, variety marine organism in underwater will be made of 3D contents.

Objective: This experiment investigated the effects of supplementing vitamin D₃-fortified sow and progeny diets with 25(OH)D₃ on growth performance, carcass characteristics, immunity, and pork meat quality. Methods: The present study involved the assessment of supplementing the diet of sows and their progeny with or without 25 (OH)D₃ in a 2×2 factorial arrangement on the performance and production characteristics of wean-finish pigs. Forty-eight multiparous sows were assigned to a basal diet containing 2000 IU/kg vitamin D₃ and supplemented without (CON) or with (TRT) 50 ㎍/kg 25 (OH)D₃. At weaning, a total of 80 pigs each from CON and TRT sows were allocated to weaning and growing-finishing basal diets fortified with 2,500 and 1,750 IU/kg vitamin D₃ respectively and supplemented without or with 50 ㎍/kg 25(OH)D₃. Results: Sows fed 25(OH)D₃-supplemented diets improved pre-weaning growth rate of nursing piglets. A significant sow and pig weaning diet effect was observed for growth rate and feed efficiency (p<0.05) during days 1 to 42 post-weaning. Pigs consuming 25(OH)D₃-supplemented diets gained weight faster (p = 0.016), ate more (p = 0.044) and tended to convert feed to gain more efficiently (p = 0.088) than those fed CON diet between days 98 and 140 post-weaning. Supplemental 25(OH)D₃ improved water holding capacity and reduced drip loss of pork meat, increased serum 25(OH)D₃ level, produced higher interleukin-1 and lower interleukin-6 concentrations in blood circulation, downregulated myostatin (MSTN) and upregulated myogenic differentiation (MYOD) and myogenic factor 5 (MYF5) gene expressions (p<0.05). Conclusion: Supplementing vitamin D₃-fortified sow and wean-finish pig diets with 50 ㎍/kg 25(OH)D₃ significantly improved production performance suggesting their current dietary vitamin D₃ levels are insufficient. In fulfilling the total need for vitamin D, it is strongly recommended to add 50 ㎍/kg 25(OH)D₃ "on top" to practical vitamin D₃-fortified sow and wean-finish pig diets deployed under commercial conditions.

D-Tagatose production from D-galactose was investigated using 35 type strains of American Culture Type Collection (ATCC) and Korean Collection for Type Cultures (KCTC) which have potential to produce D-tagatose. Enterobacter agglomerans ATCC 27987 was selected as a D-tagatose producing strain due to its short fermentation time and high production of D-tagatose. Optimization of the culture conditions for D-tagatose production by E. agglomerans ATCC 27987 was performed. Among various carbon sources, D-galactose was the most effective carbon source for D-tagatose production. As the D-galactose concentration was increased, cell growth and D-tagatose production increased. Effect of nitrogen sources on D-tagatose production was studied. Of inorganic nitrogen sources, ammonium sulfate was effective one for D-tagatose production and yeast extract was the most suitable organic nitrogen nutrient. The concentrations of inorganic compounds such as KH$_2$PO$_4$, K$_2$HPO$_4$, and MgSO$_4$$.$7H$_2$O were also optimized for D-tagatose production. The optimal medium was determined to contain D-galactose of 20 g/l, yeast extract of 5.0 g/l, (NH$_4$)$_2$SO$_4$ of 2.0 g/l, KH$_2$PO$_4$ of 5.0 g/l, K$_2$HPO of 5.0 g/l, and MgSO$_4$$.$7H$_2$O of 5 mg/l. The optimal environmental conditions in a 250-$m\ell$ flask were found to be pH of 6.0, temperature of 30$^{\circ}C$, and agitation speed of 150 rpm. D-tagatose of 0.41 g/l could be obtained in 24 h from 20 g/l D-galactose at the optimal culture condition without induction and cell concentration.

Unity's Cinemachine, one of the game production technologies, can produce 3D images. However, since Cinemachine is a game production tool, video creators may find it difficult because the work process of Cinemachine is unfamiliar and complicated. However, it is necessary to learn new technologies for the future of video contents that will be advanced in the future. In order to understand Chinemachine as a video producer, I would like to embody the scene of the movie. We are going to produce a storyboard scene for storytelling in Cinemachine. We defined the workflow of Unity Cinemachine while directing the scene by creating a story, and also checked the advantages and cautions. I hope it will be an opportunity to enjoy using Unity Cinemachine, which is constantly evolving.
