In this paper, we discuss the mesh segmentation problem which divides a given 3D mesh into several disjoint sets. To solve the problem, we propose a greedy method based on the merging priority metric defined for representing the geometric properties of meaningful parts. The proposed priority metric is a weighted function using five geometric parameters, those are, a distribution of Gaussian map, boundary path concavity, boundary path length, cardinality, and segmentation resolution. In special, we can control by setting up the weight values of the proposed geometric parameters to obtain visually better mesh segmentation. Finally, we carry out an experiment on several 3D mesh models using the proposed methods and visualize the results.

In recent years, as computer-generated imagery has been applied to more industries, realistic facial animation is one of the important research topics. The current solution for realistic facial animation is to create realistic rendered 3D characters, but the 3D characters created by traditional methods are always different from the actual characters and require high cost in terms of staff and time. Deepfake technology can achieve the effect of realistic faces and replicate facial animation. The facial details and animations are automatically done by the computer after the AI model is trained, and the AI model can be reused, thus reducing the human and time costs of realistic face animation. In addition, this study summarizes the way human face information is captured and proposes a new workflow for video to image conversion and demonstrates that the new work scheme can obtain higher quality images and exchange effects by evaluating the quality of No Reference Image Quality Assessment.

I aim to discover that how greatly the curriculum of Life Dance department has had an effect on the career of students majoring in dance, with research objects being Life Dance department of two universities, located on the metropolitan area. The study method, called qualitative, includes some suggestions on the curriculum of the two and comparison, analysis of job-related materials; further, it involves discussion on the influence the curriculum has had on the career as dance trainers. The results from it are as follows; first, the curriculum of the department mostly consists of pure art such as Korean dance, modern dance, ballet, but has few creative life dance programs. Second, the employment into the art area has been more often than to the counterpart. Finally, it shows that a title of a department does not make a big difference and affect the employment rate. In conclusion, as the completion of the curriculum does not always guarantee a success, it is recommended that college students get some competent certificates related to dance.

In these days, production and management of various digital contents increased because of growing internet users. Now the digital contents production system is producing video which is based on keywords and contents. This paper proposes the sensibility-based contents management system which can analyze and manage contents of video production system. Due to the sensibility-based multimedia contents management system, it is possible to analyze and manage sensibility contents what users want. As a result, by building a database, we can provide intelligent and meaningful services. In addition, contrary to low grade's contents-based production system, we can cope actively with users' demands.

By understanding the concept of transculturality, this paper tries to look at the mixedness shown in modern dance works in Korea. By shedding light on the transculturality character that Welsch, emphasizes, we will interpret the artistic transition and the art phenomena that appear in Korean dance.

To understand the properties of soil in Dokdo, we collected soil samples from 12 locations on Seodo and 23 locations on Dongdo, in Dokdo of Gyeongsangbuk-do Province in 2007-2008 and analyzed the soil's physical and chemical characteristics. Sand comprises the largest component (49.37%) of Dokdo soil, followed by silt (40.70%) and clay (9.93%). The soil structure consists mostly of sand loam, followed by loam and silt loam. The pH level of soils from Dokdo varied dramatically among sampling sites and seasons, ranging from 3.36 to 8.02. The total ion content of Dokdo soil also varies greatly among survey places and periods, but in general the total ion content was high in summer when vegetation develops, and low in spring. The exchangeable cation contents of the soil showed low levels in samples where the soil pH was low, including habitats dominated by Agropyron tsukushiense var. transiens and Echinochloa crus-galli, whereas the exchangeable cation contents were high where the organic contents were high, as in habitats dominated by Liriope platyphylla and Artemisia japonica subsp. littoricola. Soil N contents varied greatly among survey sites and higher N contents were found in soil inhabited by Chenopodiaceous plants than in habitats inhabited by other plants. The substantial differences in phosphorus contents among sites were related to excrement of black-tailed gulls. To understand the basic physical and chemical features of the soil on Dokdo, it will be necessary to conduct seasonal and long-term research on soil pH, ion contents, organic contents, N and P, as well as obtaining precise data from samples collected at different depths.

This study makes suggestions on the contents of home economics to form adolescents' values of a healthy marriage and family. For this objective, family-related contents of high school home economics textbooks between Korea and the U.S. were comparatively analyzed using a qualitative interpretation method, based on the elements of a healthy family. Obtaining nine types of high school technology & home economics textbooks (2009 revised curriculum), two types of high school home economics science textbooks (2009 revised curriculum), and five types of the U.S. home economics textbooks for grade 10 to 12, contents elements, described contents, pictures, illustration, and activity tasks of the contents were examined. This study discussed the implications of family-related content in home economics high school textbooks of Korea as well as presented suggestions to be used as basic data for the development of subject content. The results of the study can be summarized as follows. In the results of analyzing the family-related contents in home economics textbooks of both countries, Korean home economics textbooks emphasized the contents meeting a democratic and gender-equal family relationship, maintenance & creation of healthy family life culture, rational resource management, and support for children's growth & development. However, U.S. home economics textbooks focused on elements such as economic stability of family, stable food, clothing, and shelter, open conversation, support of children's growth & development, rational resource management, sharing family roles, healthy citizenship, and harmony between work and family.

Ginkgolides (GK) and bilobalide are valuable compounds that belong to the lactone terpene. The contents of these metabolites were determined by HPLC from female and male tree of Ginkgo biloba L. The productivity of G. biloba cells was also compared with the corresponding individual trees. High variations in the ginkgolides and bilobalide were observed from different individuals, plant parts, and cultured cells. The ginkgolides and bilobalide contents were different depending on the plant parts. Callus was obtained from various plant tissues, and NAA was better at callogenesis than 2,4-D in both the female and male trees. The plants and their corresponding cells showed considerable variation in their ginkgolides and bilobalide concentrations. The ginkgolides and bilobalide contents were not correlated with the production between dominant trees and their corresponding cells. Light irradiation enhanced the production of GK-A and GK-B, however, the concentration of bilobalide decreased under dark conditions.
