The history of contemporary art in the 20th century can be said the history of changes. Today the variety of objects destroy the boundaries of each genre. This study aims to understand the relationship between fashion and art that becomes closer by examining contemporary art in the Gwangju Biennale 2008 to enlarge the range of understanding of mutual communication between contemporary art and fabrics which are the object of fashion. The research method was to investigate the characteristics and expression methods of object fabrics shown in contemporary art through the review of papers published at home and abroad, related literatures, and Internet materials. Also, the meaning, technique, and methods of fabrics were analyzed from works introduced in the Gwangju Biennale 2008. In order to achieve this purpose, fabric was examined as the object of work in Gwangju Biennale 2008. As a result, it is found that fabric plays an important role in changing environment newly with more dynamic, abundant, and comfortable and softer feeling than any other artistic materials and enlarging the boundaries of artistic materials by exploring formative possibility. Furthermore, its multi-dimensional expression characteristic presents unbounded possibility. Fabric which has long formed close relationship with human life has taken its place as one genre now. It departs from the past principles of fabric handicraft and the restriction of a classical norm and becomes characteristic of very wide-ranging selection of materials and free expression. Its soft and warm texture provides emotional stability for a human. Although the peculiarity of fabric as an active concept to human environment and new materials and technique based on the aesthetic consciousness of a human rely on the high development of industry, it is significant that artists' liberation from their concept and material sense is accompanied by the expression of freedom.

The development of radish collectors has the potential to increase radish yields while decreasing the time and dependence on human labor in a variety of field activities. Stress and fatigue analyses are essential to ensure the optimal design and machine life of any agricultural machinery. The objectives of this research were to analyze the stress and fatigue of major components of a tractor-mounted radish collector under dynamic load conditions in an effort to increase the design dependability and dimensions of the materials. An experiment was conducted to measure the shaft torque of stem-cutting and transferring conveyor motors using rotary torque sensors at different tractor ground speeds with and without a load. The Smith-Watson-Topper mean stress equation and the rain-flow counting technique were utilized to determine the required shear stress with the distribution of the fatigue life cycle. The severity of the operation was assessed using Miner's theory. All running conditions produced more than 10⁷ of high cycle fatigue strength. Furthermore, the highest severity levels for motor shafts used for stem cutting and transferring and for transportation joints and cutting blades were 2.20, 4.24, 2.07, and 1.07, and 1.97, 3.81, 1.73, and 1.07, respectively, with and without a load condition, except for 5.24 for a winch motor shaft under a load. The stress and fatigue analysis presented in this study can aid in the selection of the most appropriate design parameters and material sizes for the successful construction of a tractor-mounted radish collector, which is currently under development.

The purpose of this study was to classify noodle meals into a few groups according to their menu patterns and cooking methods from the 318 noodles and Ttokgook menus of 360 elementary school foodservices around Busan and Gyeongnam province. Noodle meals with high frequency were also analyzed by season and region to give information for menu planning and to improve elementary school foodservices. The menus were collected from the internet(http://www.kdclub.com) and the home pages of elementary schools between December 2004 and September 2005. Taking all kinds of noodle meals together, the serving frequencies were significantly different among regions, but were not different from season to season. Three different menu patterns were revealed from the collected noodle menus. The most frequently served menu pattern was 'main dish+starchy food & dessert+fruit & beverage+kimchi'. Gooksu, Ttokgook, Udong, and Kalgooksu meals were served with this menu pattern. The menu pattern of Jajangmeon meal was 'main dish+side-dish+starchy food & dessert+fruit & beverage+(kimchi)'. For the Bibimmeon and the spaghetti meals 'main dish+soup+starchy food & dessert+fruit & beverage+kimchi' was used. Ttigim, Danmugy, Saengchae, and chicken were frequently selected as side dishes in the overall noodle menus. More side dishes of a wide variety were served in Ttokgook meal, whereas Danmugy was the most preferred food item as a side dish with Jajangmeon and Udong meals. Comdog, Mandu, Ttok, Matang, and doughnut were preferred food items as a 'starchy food & dessert' with most kinds of noodle meals, except spaghetti with which only garlic-bread was served. The fruit and beverage items were not different with the majority of noodle meals. These results suggest that cost food habits, compatible flavor combinations, and food preference of children rather than nutritional considerations contributed to the selection of food items for the components of noodle meals in the school foodservices.

Since FAO introduced the Globally Important Agricultural Heritage Systems(GIAHS) in 2002, 36 sites of 15 countries so far have been listed on GIAHS. This study aims to find the important agricultural heritages of Korea and to prepare the methods for them to be selected as GIAHS. We have analyzed the proposals of the 36 GIAHS listed in order to study the characteristics of their components of the agricultural heritage which worked for being selected. To analyze the components of the agricultural heritage first, agricultural heritage was classified into 13 types and 42 components in light of GIAHS criteria. Then central themes were set to analyze the relevant contents in the proposals. They were, the type of GIAHS Site, significant agricultural landscape, the agriculture-forestry-fisheries-livestock linkage systems, the multi-layered, inter-cropping, circulation cultivation systems, the soil and water management systems, the conservation of agrobiological diversity and genetic resources, the history of the agricultural heritage, the succession of traditional farming techniques, the cultural diversity and so on. Most GIAHS are located in mountains, grasslands, rivers and coasts, desert than in plains, through which GIAHS assure us that it is the heritage of human challenge to overcome the harsh geographic environment and maintain a livelihood. In these sites the traditional farming techniques are carried on, such as mountain clearings, terraced rice paddies, and burn fields, and the unique irrigation systems and agricultural landscapes are well maintained, and the eco-friendly traditional farming techniques utilizing abundant forest resources and agriculture are well handed down. The origin or home of crop growing, a variety of genetic crop storage, the world's largest crop producer and preserving cultural diversity are also important factors for the selection.

Embryonic stem cells are capable of differentiating into a variety of cell lineages. However, the ultimate results of differentiation in vitro greatly depend on the duration of treatment and kinds of differentiating inducers added. In order to investigate the efficiencies of various differentiation inducers and the methods of treatment, we examined differentiation patterns of human embryonic stem cell (hESC, MB03) according to several different protocols. Exp. I) Upon differentiation using retinoic acid and ascorbic acid (RA/AA), embryoid bodies (EB, for 4days) derived from hESC was exposed to Rh (10$^{-6}$ M) and AA (50 mM) for 4 days, and were allowed to differentiate in N2 medium for 7, 14, 21, or 28 days. Exp. II) When bFGF was used, neuronal precursor cells were selected for 8 days in N2 medium after EB formation. After selection, cells were expanded at the presence of bFGF (20 ng/ml) for another 6 days followed by a final differentiation in N2 medium for 7, 14, 21 or 28 days. Exp. III) In addition, to examine the effects of neurotrophic factors in the production of mature neurons, groups of cells were exposed to either BDNF (5 ng/ml) or TGF-$\alpha$(10 ng/ml) during the 28 days of final differentiation. Differentiation patterns of RA/AA or bFGF treated groups were very similar; approximately 82% and 83% of the cells, respectively, were positive for anti-NF200 antibody, while it was about 10% and 11%, respectively, for anti-NF160 antibody in 28 days in N2 medium. Alsor, cells expressing TH were as low as 5%, while the cells doubled when matured at the presence of either BDNF or TGF-$\alpha$. Cells immunoreactive to anti-GAD antibody were approximately 20%. These results suggest that a maturation step rather than differentiation induction step, which is formation of EB, effects more decisively to the ultimate differentiation pattern.

Abiotic stress adversely affects crop growth worldwide. Drought of the major abiotic stresses have the most significant impact on all of the crop. The main objective of this study was to assess the effects of drought stress on photochemical performance and vitality of maize (Zea mays L.). The photochemical characteristics were analyzed in the context of period of drought stress during the maize growth. Drought experiment was carried out for four weeks, thereafter, the drought treated maize was re-watered. The polyphasic OJIP fluorescence transient was used to evaluate the behavior of photosystem II (PSII) and photosystem I (PSI) during the entire experiment period. In drought stress, the performance Index (PI) level was reached earlier when compared to the controls. For the screening of drought stress tolerance the drought factor index (DFI) of each variety was calculated as follow DFI= log(A) + 2log(B). All the fourteen cultivars show DFI ranged from -0.69 to 0.30, meaning less useful in selection of drought tolerant cultivars. PI and electron transport flux values of fourteen cultivars were to indicate reduction of photosynthetic performance during the early vegetative stage under drought stress. In conclusion, DFI and energy flux parameters can be used as photochemical and physiological index.

This study is to investigate the determinants of consumption expenditure by considering potential expenditure factors such as socioeconomic, fishing village tourism behavior, motivation for visits, and optional attributes of tourists at Muchangpo webfoot octopus and finespotted flounder festival in Boryeong. The analysis data are 300 questionnaires of visitors to the festival during the 2018 Muchangpo Mysterious Sea Road Webfoot Octopus and Finespotted Flounder Festival from March 17 to April 8, 2018. As a result of analyzing the factors of consumption expenditure of tourists to the festival in Boryeong, socioeconomic factors such as gender and residential groups outside Chungcheong-do have a positive (+) effect on consumption expenditure. Among the factors of fishing village tourism behavior, the only number of days of stay more than one night has a positive (+) effect on consumption expenditure. In addition, in the analysis of factors for motivation to visit the festival, fun/interest and simple rest/leisure have a significant positive (+) effect on expenditure whereas stress relief have a negative (-) effect on expenditure. In the analysis of the factors of festival selection attributes, tourism facilities has a significant positive (+) effect on expenditure, but natural scenery and excellent natural scenery show a significant negative (-) effect on expenditure. The main implications that can be obtained from the results of this study are as follows. First, it suggests that the promotion should be actively conducted outside of Chungcheong Province in order to achieve the original purpose of revitalizing the local economy from the Muchangpo webfoot octopus and finespotted flounder festival. Second, it indicates that there should be a variety of unique high-quality festival programs differentiated from other local festivals, promoting the existence of simple rest/leisure facilities rather than webfoot octopus boat fishing experiences or natural scenery (i.e., mysterious road and sunset) in order to attract festival tourists' spending at the Muchangpo webfoot octopus and finespotted flounder festival.

Television news programs are becoming significant source of health information. This study aims at investigating the current state of health coverage of the prime time news program in Korea. Data were collected from KBS 9 0'clock news in the period of thirteen months. from December 1. 1998. to November 1. 1999. The data were analyzed using content analysis method. and the reliability degree was 99.7% according to the Holsti's inter-coder reliability test. The current research classified 489 health related news items into 49 sub-categories and five health categories through content analysis. Some of the basic results of this study are as follows. 1. The frequency according to health category, health maintenance promotion(57.3%) topped followed by disease prevention(23.2%), disease treatment(14.9%), life ethics(4.0%), and growth development(0.6%). 2. According to human developmental age. for the most part(80.1 %) is applicable to the entire range of human developmental age. 3. Health maintennance promotion category take top of health category by the rate of 57.3% and contain 20 sub-categories. 4. News items in the life ethics category, which had six sub-categories. occupied only four percent of the total health related news. News in the growth development category included two sub categories and occupied 0.6% of the total news items. 5. In disease prevention and disease treatment category, infectious disease(33.2%) showed the highest percentage according to the WHO's international disease classification system. Disease prevention occupied 23.2% and contained eleven sub-categories while disease treatment occupied 14.9% and included ten sub-categories. Television news coverage on health showed a wide variety of selection in terms that they are reporting various issues. This study, however, found that some news items were confusing and failing in presenting scientific evidences. It is suggested that the television coverage on health could be beneficial to most of viewers in receiving important health information and guidelines, only if they are utilizing their own sound discretion in consuming those news.
