Most animation films running on cinema or TV are based on 3D images. Domestically, a lot of 3D animations are produced, and the number of 3D animation films are on the annual rise. Many human resources relating to animation participate in a variety of domestic and foreign animation projects of domestic producers. In the animation participate in a variety resources are of more importance. As a result, many university make the effort to raise human resources for 3D animation. In this paper, we will look into the curriculum of 3D animation. In particular, based on the questionnaire survey in which domestic 3D animation producers participated, this study analyzed the survey results and tried to discuss how to rise human resources for creative 3D animation in university. It is aimed at suggesting the directions of raising human resources for 3D animation in proper 3D animation education and of their contributions to the development of the domestic 3D animation industry.

The objective of this study was to develop a fast and accurate method of variety discrimination and geographical discrimination origin of Korean angelica (Korean variety, Angelica gigas Nakai) by using TDU-GC/MS. Two peaks of decursin and decursinol, which are coumarin derivatives were identified in the range of Total Ion Chromatogram (TIC) RT 26.9-27.2 of the Korean angelica by GC/MS analysis at the time of condensation in a refrigerated condensation system after thermal desorption of sample extracts. In case of Chinese angelica (Chinese variety), ligustilide peak was detected at the RT 17.2. In order to investigate the difference of volatile components according to the geographical origin of Korean variety, the mass spectra were measured by TDU-GC/MS at the range of m/z 40-400 amu. The TIC of domestic cultivation and Chinese cultivation of the Korean variety, Angelica gigas Nakai showed the same tendency as a whole. However, in partial scans of TIC, two peaks detected at 15.54 and 16.05 of RT showed different peak patterns between Korean angelica (Korean variety) cultivated in Korea and in China. The ratio of Peak A (RT 15.54) and B (RT 16.05) was 0.0-0.2 for domestic cultivation and 0.5-2.8 for Chinese cultivation, confirming the possibility of discriminating origin by comparing the TIC peak pattern of TDU-GC/MS.

This study was conducted to reduce the phenomenon of the biased cultivation of certain mushroom varieties and to develop a competitive variety of Grifola frondosa. We developed the first Korean white commercial mushroom strain, 'Bakyeon', by crossing monokaryons derived from brown strains. We have collected and tested the characteristics of mushrooms from domestic and international genetic resources since 2018. We bred the unique domestic variety, 'Bakyeon', which has the following characteristics. The optimal temperature for mycelial growth was 25~28℃ and the optimal temperature for fruit body growth was 16~18℃. The new variety was similar to the control variety (Daebak) in terms of the pileus, which formed a pine cone shape, and the number of days of cultivation. The yield was 94.1 g/bottle, which was 23% lower than the 108.5 g/bottle yield of the control variety. When incubating the parent and control varieties, the replacement line was clear. Moreover, polymerase chain reaction analysis of mycelial DNA resulted in different band patterns between the parent and control varieties, confirming the hybrid species.

A new gerbera variety 'Yellow Wing' was released by the National Horticultural Research Institute (NHRI) in 2007. A cross was made between 'Gold Finger' with yellow and single and 'Yellow Springs' with yellow and spider in 2004. After investigation of the characteristics for 4 years (from 2004 to 2007), it was selected specially for the use of cut-flower. 'Yellow Wing' is a vigorous cultivar with yellow (RHS YO14B), green center and spider type. The flower diameter is 10.6cm. And inner ray floret and disc diameter is 2.83cm and 2.03cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height and brilliant color. We believe that 'Yellow Wing' has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.

In the modern society, magazine is a information communicating media which is an important element in assessing the whole of a nation's cultural standard. More subdivided fields of magazines are expanding according to the diversified concepts. As the variety of Korean edition of foreign magazines are increasing, the type of Women's magazines are also diversifying and expanding. By finding out the problems and analyzing the visual side of domestic women's magazines among the intense competition of the magazines, the design improvement program was requested. The analysis result from the visual side of domestic women's magazines tells us that the problem of current domestic women's magazines is that their identities are not clear. The cause can be divided into three reasons: First, it is the lack of creativity and originality. There is a limitation in arousing the readers' interests by designing the magazines with similar layouts. Second, there are no distinct design concepts in the magazines. It seems as if the uniformity is lacked as the impression the magazine gives is not clear. The diversification of layouts and the use of design elements could actually bring about a counter result. Third, the excessive advertisement pages is another reason. The ads that covers over 35% of the whole of the magazine can act as a factor that drops the readers' trust in the magazine.

Over the past decades, in vitro culture media have been developed to successfully support IVF embryo growth in a variety of species. Advanced reproductive technologies, such as somatic cell nuclear transfer (SCNT), challenge us with a new type of embryo, with special nutritional requirements and altered physiology under in vitro conditions. Numerous studies have successfully reconstructed cloned embryos of domestic animals for biomedical research and livestock production. However, studies evaluating suitable culture conditions for SCNT embryos in wildlife species are scarce (for both intra- and interspecies SCNT). Most of the existing studies derive from previous IVF work done in conventional domestic species. Extrapolation to non-domestic species presents significant challenges since we lack information on reproductive processes and embryo development in most wildlife species. Given the challenges in adapting culture media and conditions from IVF to SCNT embryos, developmental competence of SCNT embryos remains low. This review summarizes research efforts to tailor culture media to SCNT embryos and explore the different outcomes in diverse species. It will also consider how these culture media protocols have been extrapolated to wildlife species, most particularly using SCNT as a cutting-edge technical resource to assist in the preservation of endangered species.

10 of Korean domestic recommended varieties(all of them are determinate type) and 10 of introduced varieties from U.S.A.(All of them are indeterminate type) are grown in replicated field in order to clarify the varietal differences in the days from planting to blooming to ripening. The results are summarized as follows; 1. Domestic varieties showed remarkable shortday sensibility for the days from planting to blooming. The difference in sensibility between domestic and introduced was significant while within the domestic group the differences were not significant. 2. The days from planting to blooming were linearly shortened in accordance with the delayed planting from the late April through the late June. 3. Annual variation in days from planting to blooming was not noticeable in the domestic varieties while the introduced ones showed remarkably. 4. The days from blooming to ripening were significantly shortened for the introduced varieties but not significantly for the domestic varieties accordingly with the delayed planting. The mean shortest days of domestic varieties were longer than the mean shortest days of introduced varieties. 5. The days from planting to blooming was shortest when a variety was grown during early August through middle September (with 12.5~13.5 hrs day length and 22~$27^{\circ}C$ temperature), and the days from blooming to ripening were also shortest when a variety was matured within same duration. These were true for the varieties of both groups.

Background: At the end of the'Waste Drug Disposal Project', collection and disposal of waste drugs remain a social issue. Objective: This study aimed to provide suggestions to improve the drug waste management system in Korea by comparing domestic and overseas relevant programs. Methods: This is a comparative study between South Korea, Australia, Canada, France, and the US. These overseas countries were selected because they have been operating waste drug management programs continuously to date. Comparison was conducted by a pre-determined analysis frame including legal regulation, enforcement program and its performance. Results: All selected countries except Australia had legal regulations on drug wastes. The US had the largest variety of drug waste disposal methods. Canada had recommended that pharmacies actively participate in drug waste withdrawal programs. France had the largest variety of methods to promote relevant programs, including window sticker, SNS, and app, as well as the highest level of awareness and participation. Australia had the lowest level of awareness and participation in pharmaceutical waste management programs. Pharmaceutical companies took responsibility of paying for these programs in the selected overseas countries. Conclusion: Further efforts should be made to establish a clear guideline including the role of pharmaceutical companies, and to develop various methods for the public to be aware of appropriate ways of disposing drug wastes in Korea.

Although most lemons are imported into Korea, their consumption is increasing. Development of domestic varieties of Jeramon and Minimon is currently underway in an effort to meet the increasing demand for fresh lemons. In this study, an analysis of the physicochemical characteristics of Jeramon and Minimon, including their flavor components and antioxidant properties, was conducted. The results revealed that these new varieties of Korean lemon can be regarded as good sources of antioxidants and phytochemicals. Compared to Sunkist, the most consumed lemon variety in Korea, Minimon contained more than twice as much β-cryptoxanthin, and the content of L-ascorbic acid was more than three-four-fold higher in both Minimon and Jeramon. In addition, results from measurement of DPPH and ABTS radical scavenging activities indicated that Jeramon extract exhibited the highest antioxidant activity. In the volatile profile analysis, the profiles of volatile components showed high similarity among the three lemon samples, and the composition ratio was largely dominated by terpenoids. A markedly higher ratio of d-limonene and thymol was detected in the Minimon variety compared with that in the other two varieties. Collectively, the findings from this study on Korean lemon varieties provide a basis as well as valuable guidance for breeding domestic lemon varieties.

This study was conducted to reduce the phenomenon of the biased cultivation of certain mushroom varieties and to develop a competitive variety of Pleurotus nebrodensis. We have collected and tested characteristics of genetic resources from domestic and overseas varieties since 2015. We bred the domestic variety 'Boram'. The optimal temperature was 26~29℃ for mycelial growth and 15~18℃ for fruit body growth temperature. This variety was similar to the control variety (Uram) in terms of the number of cultivation days and yield per bottle. The shape of the new cultivar was round, whereas that of the control group was spatula-like. The yield was 181.1 g/bottle, which was statistically similar to that of the control variety. When incubating the parent and control varieties, the replacement line was clear. Moreover, polymerase chain reaction analysis of mycelial DNA resulted in different band patterns between the parent and control varieties, confirming the hybrid species.
