The purpose of this study is to attempt to diversify artistic expression through combinations of the twelve zodiac animals and origami techniques and to propose new directions for fashion design by applying these to fashion accessory bag designs. For the research method, this study researched the representative forms and characteristics of twelve zodiac animals based on the cultural background. Also, diverse cases of origami techniques were sought to apply them to the development of bags. The results are as follows. First, expressed forms of the Chinese zodiac were newly expanded by realizing the form of Chinese zodiac animals through various origami techniques. Origami work displays abstract visual effects rather than intuitive feelings or expressions of flat designs. With this, detailed realizations could be made through the characteristics and cultural implications of animals. Second, the work created in this study utilized zero-waste patterns that use origami techniques on one whole piece. During pattern production, folded parts were marked without waste and the outer fabric and lining were produced. Patterns were all symmetrical lines so most forms were expressed with squares and equilateral triangles. Third, through actual work produced using fabric instead of paper, effects that are brought about through folding are determined in diverse ways according to fabric textures or material types and thicknesses. When paper is folded, shapes are created as folded, but fabric requires the use of supportive material to create the effects of origami. Polyester and blended fabric were easy to use with high levels of function and practicality. Through such diverse production attempts, fixing methods, hand sewing, sewing machines, double-sided tape, and leather adhesive were used.

In order to evaluating physiochemical properties of soil under minimum tillage and direct seeding cultivationon dry rice paddy, we conducted to analyze the soil physiochemical characteristics in treatment with 2-yearminimum tillage and dry direct seeding (2MT), 3-year minimum tillage and dry direct seeding (3MT), andtillage transplanting cultivation (TT). As results of analyzing soil organic matter (OM) contents with 2 cm soildepth of interval from surface to 30 cm, OM contents with surface soil from 0 to 2MT and 3MT were higherthan TT, recorded 34.6, 28.1 and 19.8 g kg-1, respectively. But until 20cm in soil depth, it was not so large onthe deviation of OM contents among the 3 treatments comparing with 2cm surface. Beneath 20 cm in soildepths, 2- and 3-year, OM contents in TT were distributed to be lower than 2MT and 3MT. The contents oftotal nitrogen in 2MT and 3MT were higher than the content in TT across the soil profile. Consequently,though minimum tillage and direct seeding farming is obviously the practice to saving of machinery work andlabor, other practices such as continuously input OM should be needed to achieve carbon sequestration goalthrough minimum tillage and direct seeding on dry paddy.

In order to evaluate drought risk at upland according to climate change scenario (RCP8.5), we have carried outthe simulation using agricultural water balance estimation model, called AFKAE0.5, at 66 weather stationsites in 2020, 2046, 2050, 2084, and 2090. Total Drought Risk Index between the first month (f) and last month(l) (TDRI(f/l)) and maximum continuous drought risk index (MCDRI(f/l)) were defined as the index foranalyzing pattern and strength of drought simulated by the model. Based on distribution maps of MCDRI(1/12), drought strength was predicted to be most severe in 2084 for all regions. Some regions showed severerisk of drought meaning over 20 days of MCDRI (1/12) in the other years, while MCDRI (1/12) in otherregions did not reach 5 days. Even though maximum value of TDRI (1/12) in 2090 was greater than in 2050,more severe drought risk in 2050 than in 2090 was predicted based on MCDRI (4/6). It implies that droughtrisk should be assessed for each crop with its own growing season.
기후변화에 따른 국내 벼 품종과 재배기술의 적응성에 관한 고찰

In recent years, the temperature of Korea has been rapidly increasing due to global warming. Over the past 40 years, the temperature of Korea has risen by about 1.26℃ compared to that in the early 1980s. By region, the west region of the Gangwon Province was the highest at 1.76℃ and the Jeonnam Province was the lowest at 0.96℃. As the temperature continues to rise, it is expected that the rice yield will decrease in the future using the current standard cultivation method. As a result of global warming, the periods in which rice cultivation could be possible in regions each year has increased compared those to the past, showing a wide variety from 110 days in Taebaek to 180 days in Busan and Gwangyang. In addition, the transplanting time was delayed by 3-5 days in all regions. The average annual yield of rice showed an increasing trend when we analyzed the average productivities of developed varieties for cooked rice since the 1980s, especially in the early 1990s, which showed a rapid increase in productivity. The relationship between the average temperature at the time of development and the rice yield was divided into the periods before and after 1996. The higher the average temperature, the lower the yield of the developed varieties until 1996. However, since 1996, the increase in the average temperature did not show a trend in the productivity of the developed varieties. The climate change adaptability of developed rice varieties was investigated by analyzing the results of growing crops nationwide from 1999 to 2016 and the change in the annual yields of developed varieties and recently developed varieties as basic data to investigate the growth status of the crops in the country. As a result of annual comparisons of the yields of Taebongbyeo (2000) and Ungwangbyeo (2004) developed in the early 2000s for Odaebyeo, which was developed in the 1980s, the annual yields were relatively higher in varieties in the 2000s despite the increase in temperature. The annual yields of Samgwangbyeo (2003) and Saenuribyeo (2007), which were recently developed as mid-late-type varieties, were higher than those of an earlier developed variety called Chucheongbyeo, which was developed in the 1970s. Despite the rapid increase in temperature, rice cultivation technology and variety development are well adapted to climate change. However, since the biological potential of rice could reach its limit, it is necessary to develop continuous response technology.
