The purpose of this study was to examine the biological activities of gamma-irradiated Teucrium veronicoides. In photostimulated luminescence analysis, non-irradiated sample showed lower than 700 photon counts (PCs), whereas irradiated (5 and 10 kGy) samples showed higher than 700 PCs. The thermoluminescence ratio of non-irradiated samples was less than 0.1, whereas the values of irradiated samples were greater than 0.1. Electron spin resonance analysis was performed confirmed for irradiation identification. The total phenolic contents of hot-water and 50% ethanol extracts were higher than those values after irradiation at 10 kGy. Regarding 1,1-diphenyl-2-picrylhydrazyl radical inhibitory activity, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, antioxidant protection factor, thiobarbituric acid reactive substance inhibitory activity as antioxidant test and xanthine oxidase inhibitory activity, the effect of gamma irradiation had on significant effects. On the other hand, ${\alpha}-amylase$ inhibitory activity of 10 kGy-irradiated hot-water extract was 23.6% higher than that of the non-irradiated sample. Thus, gamma irradiation could be used for the long-term storage of Teucrium veronicoides.

This study surveyed 60 early childhood teachers at the kindergartens and day care centers in Incheon Metropolitan City to examine the contents and extent of the teachers' knowledge on early childhood history education by using the definition map designed by Novak and Gowin(1984). To be more specific, the researcher asked the participating teachers through group meetings to draw the definition maps and analyzed them. The results were as follow. First, 11 categories for high level definition of early childhood history education used by early childhood education were identified, among which the most frequently used high level definition were 'life style' followed in order by 'culture/art' and 'great men.' Second, in terms of the average number of dependent definitions included in the given high level definitions, the largest was 'life style' which was followed in order by culture/art, activity methods. It means that the widest area of early childhood teachers' knowledge on early childhood history education was about 'life style,' while it shows that the extent of knowledge on teaching-learning methods was relatively wide. However, in the case of great men, although it was frequently recognized in the high level of definition it was not so in the dependent definitions, meaning the extent of their knowledge was rather narrow. Scholars explain that the higher the teachers' attention and knowledge about the content of curriculum the more options of teaching method they tend to employ to teach in a more extensive and diverged way. Therefore, in order to improve early childhood education, efforts should be more focused on deepening and systemizing the knowledge of early childhood teachers.

In the present study, we investigated the anti-proliferation activity of Citrus grandis Osbeck peel (CGP) in HL60 (human promyelocytic leukemia) cells. It was found that 80% ethanol extract of CGP could inhibit the cell growth in a dose-dependent manner ($250{\sim}1,000{\mu}g/mL$), which was associated with morphological changes and apoptotic cell death such as depolarized mitochondrial membrane, formation of apoptotic bodies and increased populations of apoptotic sub-G1 phase. The results indicate that CGP extract inhibits the growth of HL60 cancer cells by the induction of apoptosis, which may be mediated by its ability to change the Bcl family proteins and increase the activation of caspase-3 and PARP. Therefore, it is suggested that CGP has the potential to provide a remarkable natural defense against the proliferation of HL60 cells.

In this study, we investigated the change of antioxidant activity and flavonoid contents by fermentation of Citrus grandis Osbeck peel (CGP) using the Saccharomyces cerevisiae (KCCM35053), comparing to unfermented CGP. Total flavonoid content in the fermented Citrus grandis Osbeck peel (FCGP) was 3,768 g/100 g sample and higher than that of CGP. The antioxidant activities of FCGP was determined by DPPH, hydroxyl, alkyl radicals, and hydrogen peroxide scavenging assays. FCGP showed higher activities than CGP in all scavenging assays. The $IC_{50}$ values of FCGP were 261.3 ${\mu}g$/mL for DPPH; 1,474 ${\mu}g$/mL for hydroxyl; 90.9 ${\mu}g$/mL for alkyl and 1,195 ${\mu}g$/mL for $H_2O_2$ in respective scavenging assays. Flavonoid compositions of both samples were determined by liquid chromatography/mass spectrometry (LC/MS). In the spectrum FCGP was similar to CGP in the contents of neohesperidin, naringin and an unknown No. 7 compound, but some unknown compounds (No. 1, 2, 4, 5, 6) were higher than CGP in each flavonoid contents. Therefore, the fermentation of CGP could increase the contents of unknown compound and improved antioxidant activities.

This paper explores the use of Korean wrapping cloths (bojagi) in the late Joseon period and the types of decorations applied to them. Korean wrapping cloths called bojagi are pieces of cloths used by households of all social classes for practical purposes such as wrapping presents and covering food. In addition to the basic purposes, the making of bojagi was also an activity to express the down-to-earth wishes and the satisfaction of creation by the designer. With regard to the decorative feature of Korean wrapping cloths, five types of, patchwork, embroidered, painted, printed, and oiled-paper wrapping cloths, were examined. The patchwork wrapping cloths (jogakbo) show the frugality of Joseon women in addition to the well-developed composition skill of lines and colors. The embroidered wrapping cloths were prepared for special rituals and ceremonies such as weddings. Painted wrapping cloths were decorated with a Chinese-colors technique (called dangchae) or sometimes with black ink painting. For printed wrapping cloths, various sizes of woodblock printings and roller printings were used. Although monotone black ink was the main color applied to the printing, there was also wrapping cloths made from chintz having brilliant fast colors. Oiled-paper wrapping cloths called sikjibo were in use only for covering food. Cut-out work was employed to decorate it.

This study examined traditional dance programs in cultural and arts education in local children's centers. We aimed to contribute to the voluntary and active participation of children in cultural and arts education through differentiated cultural and arts educational programs. Interviews were conducted from March 2016- June, 2016 at A Regional Children's Center in Chungnam. Once a week, a 50-minute were held 16 Session as "learning traditional joyful dance". After completing the program, 25 children who participated in the program were asked about the good points and disappointments regarding the program. The interviews used open, structured questions that have been primarily used in phenomenological research. The list of questions was prepared in advance according to the research purpose. The results of the study are as follows: The evaluation of the first program was generally positive. By experiencing activities through cultural and arts education through traditional dance programs for children, children learned to be polite. It also changed positively in conversation. Children who showed negative attitudes toward traditional dance programs gradually participated in activities. Second, I examined the evaluation of lecturers who teach traditional dance. The children's response to the program was positive, with sincere and responsible lecture preparation and progress. The instructor prepared the class in advance, welcomed the children and ran the class in good faith. Instructors who taught traditional dances were proficient in dance, majored in dance and teaching children. The learning effect was high by the instruction of the good dance movement. Rich in lecture experience, he is proficient in dealing with children in class. Material was delivered according to the child's dance level.

The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

This study's purpose is to find the ancient costume of the folk song's words on Dunhuang manuscripts in the background wass-carvings sculptures and several art works. Dunhuang had played the part of major route between ancient China and Europe. It is located on kam-suksong the west of China. 1. In the aspect of costume arrangement hair Styling is represented by Naegagyo, Wangyesa, Kyongburak, Bonkwyun, Pogurak, Chonsonja, Namgaja, Tongson-ga, Ojesa, Chanboja in Dunhuang manuscripts. tugue is sim-ilar to Sabyokkwanja in Naegagyo as of that time these kinds of Kwan-ja was very popular. It was told that emperor's wife concubine and maid of honor would wear kwnaja favorably. And the kinds of Tugeu is PuyongKwyunkye, Aangunkye, Chunkye from Kyuwanjon except Sangunkye, Ounkye in Dunhuangsa. 2. Jangdaegy is guoted from Kyuw-anjon -A series of the chinese history book-tells us about women's make-up . The narmes of make-up are Hongjang Unjan--g, Yiljang chwejang, Tam-ajang Murgjang, Sanagjang, Light-make up are referred in Naegagyo is included as packjang Besides we can find other make-up skills Huphwaro and Rujang from the Kaewonch onbon-wisa which was Yangkwibi's episodes. We can find the a corpus of song's words about cosmetic custom in Kor-ea. Which is 'Haecho' folk song in the souther-en costal regions 'Jinggum' folk song in Kim-hae regions and so on.... It's words is similar to Dunhuangsa in China. 3. Bichun inherited to China with India Bud-dism art in the middle of Dunhuang wall-pain-tings is one of the important Buddist saint. Sometimes it is painted with Giakchun Its arms of fly-dnacing in heaven with colored belt on body has almost the form of play on the musical instrument, We can see seasily the form in the painting of Buddist ser-mon. It was progressed and changed with the background of chinese traditional culture. When Dang's period came the color was chan-ged lighting dark blue has rhythmical and viv-id power of life. 4. Among the corpus of song's words which express the singers' system and rites of their tradition or habits. Dunhuang manuscripts des-cribes on behalf of the folk song's words in tra-ditional costume. This is following: (1) Naegagyo o sabyokwanja o Chyrasam o Rashang (2) Wangyesa o Sokryugun o Costume for fisher man (3) Bungajang of the chanboja o Ajang (4) Pongkwyun o Chongui (5) Tongsongs o Junofore (6) Namgaja o thin-Rasam (7) Yuchungnang o Hongsam o Sokryugun : The color of red costume (8) Kyongburak o Hongrasam o Sokryugun : Costume for charming woman Therefore traditional costume could be extracted according to the Dunhuang folk song's words out of culture such as learning rit-es three-obedience four-virtues and in-struction. As the same time it reflects ancient China's characteristics directly. I would endeavor to development for the history of the costume furher creative design and participat-ed in research activity with concerns forward continuously.

Dietary life is said to be consummated even to a phase of art from phase of survival, recognition, selection and preference. Dietary life, from a sheer earing, is now transforming itself into a joy, and therefore, function of foodstuff packaging demand diversification rather than a simple packaging. Recently, socio-economic environment is showing conspicuous changes in that there are increasing number of working couples nuclear family, old-age population, social activity and improvement of living standards. Such a change in the living environment has much impact on our dietary life. Particularly, an age when cake and cookies of western origin were all but strange is gradually phasing out, while it is deemed to be improper to overlook the fact that bread and cakes are solidifying their position as part of foodstuff meanies for on dietary life. Of cakes and cookies, cakes have come to enjoy a position whereby they are regarded as part of an imperative for family banquets, various get-together and birthday celebration, etc., with a significant improvement that caters to our taste vis-a-vis an stage of introduction of cakes. At the time when reined foreign bakeries, one after another , are contemplating to make an inroad into Korea, and when the distribution market is to be opened fully in July of 1993, Korea bakeries that have been building up their position within the domestic market are expected to face a considerable number of difficulties. Accordingly, under such circumstances of the time text we are in it is attempted in this study to map out measures that may contribute to the strengthening of the products of business enterprises and improvement of corporate image that may appeal to feeling and emotions of consumers packaging that could attain objectives, and package design planning that, as an important factor for playing its own share in the restoration of humanism that is being alienated, may appeal to consumer sensitivity, rather than packaging that is being utilized merely as tool designed for marketing
