현대 사회에서 첨단 기술의 발전은 예술의 양상을 빠르게 변화시키고 있다. 생성형 인공지능 기술의 발전은 인류의 전유물이라 여겨왔던 창작 행위에 기존에는 보지 못했던 색다른 표현을 제공했다. 또한, 전통적 기법 을 고수하던 예술인들에게 새로운 예술 창작의 발현 방식을 제시하였다. 하지만 나날이 발전하는 인공지능 기술에 비해, 이를 활용한 구체적인 미디어아트 제작 과정 연구는 아직 국내에서는 미비하다. 본 논문은 인 공지능 기술을 활용한 미디어아트 해외 사례를 탐구한다. 그리고 Text-to-Image 인공지능 생성 모델과 게임 엔진 Unreal Engine 5를 이용하여, 국내에 자리 잡지 않은 생성형 인공지능을 활용한 작품 제작 방법론과 창 작자들에게 인공지능 이미지 생성 모델의 확장성을 제시한다.

Hierarchically porous, chemically activated carbon materials are readily derived from biomass using hydrothermal carbonization (HTC) and chemical activation processes. In this study, empty fruit bunches (EFB) were chosen as the carbon source due to their sustainability, high lignin-content, abundance, and low cost. The lignin content in the EFB was condensed and carbonized into a bulk non-porous solid via the HTC process, and then transformed into a hierarchical porous structure consisting of macro- and micropores by chemical activation. As confirmed by various characterization results, the optimum activation temperature for supercapacitor applications was determined to be 700°C. The enhanced capacitive performance is attributed to the textural property of the extremely high specific surface area of 2861.4 m2 g–1. The prepared material exhibited hierarchical porosity and surface features with oxygen functionalities, such as carboxyl and hydroxyl groups, suitable for pseudocapacitance. Finally, the as-optimized nanoporous carbons exhibited remarkable capacitive performance, with a specific capacitance of 402.3 F g–1 at 0.5 A g–1, a good rate capability of 79.8% at current densities from 0.5 A g–1 to 10 A g–1, and excellent life cycle behavior of 10,000 cycles with 96.5% capacitance retention at 20 A g–1.

This experiment was carried out to investigate the effect of harvesting time of Italian ryegrass (Lolium multiflorum Lam; IRG) in spring on dry matter (DM) yield. IRG cultivars ‘Kowinearly’ and ‘Greenfarm’ were seeded at 50 kg/ha and grown on rice paddy fields. There was no difference in growth characteristics between both varieties before winter. However, cold tolerance of Kowinearly was higher than that of Greenfarm, as demonstrated by post-wintering growth characteristics. The heading date of both varieties was affected by the spring weather. The IRG was harvested three times at 5-day intervals beginning from 9 May. The DM yield of Greenfarm was 6,306; 7,335; and 8,109 kg/ha, and that of Kowinearly was 7,498; 9,196; and 10,449 kg/ha at the three consecutive harvests. The delay of the harvesting time for 5 and 10 days increased the DM yield of Greenfarm by 16% and 29% and that of Kowinearly by 23% and 39%, respectively, compared to the yield at first harvest (p < 0.05). Therefore, IRG harvest later than early to mid-May is expected to increase productivity. The feed values of Greenfarm were: 12.2% of crude protein (CP), 34.5% of acid detergent fiber (ADF), 57.7% of neutral detergent fiber (NDF), 61.6% of total digestible nutrients (TDN), and 72.3% of in vitro DM digestibility (IVDMD). For Kowinearly, these values were 16.4% of CP, 30.4% of ADF, 52.7% of NDF, 64.9% of TDN and 79.0% of IVDMD.

The present study investigated the effects of different seeding rates on growth characteristics and seed productivity of the “Kowinearly” cultivar of Italian ryegrass (Lolium multiflorum Lam.) in paddy fields. Sowing Kowinearly in paddy fields under growing rice at the rates of 20, 30, 40, and 50 kg/ha resulted in seed yields of 1.57, 1.92, 2.06, and 2.09 ton/ha, respectively. Seed yield of Kowinearly was the highest at a seeding rate of 50 kg/ha (p<0.05), at which the cultivar was able to survive in winter and the weed ratio was low. Under these conditions, most growth characteristics such as winter survival (85%), weed ratio (10%), stems per square meter (1,006) were superior than those sown at other seeding rates (p<0.05). In addition, it has been reported that the economic efficiency of the 50 kg/ha seeding rate was higher than that of the other seeding rates.

The objective of this study was to determine the effect of harvesting time of rice on growth characteristics and dry matter yields of Italian ryegrass (Lolium multiflorum Lam., IRG) ‘Kowinearly’ after seeding them in paddy field. Experiments were performed in National Institute of Animal Science, RDA (Cheonan, Choongcheongnam-do province of Korea) for four years (2011~2014). Italian ryegrass variety ‘Kowinearly’ was seeded at experimental paddy fields before rice harvest in late September. Rice were harvested at 10, 20, and 30 days after seeding of IRG. As the harvest time of rice became later, the number of tillering before winter was reduced and IRG plant length before winter was shorter. The dry matter yield of IRG was also reduced. When rice were harvested at 20 days and 30 days after sowing of IRG compared to the rice harvested in autumn at 10 days after sowing of IRG, the number of tillering for IRG before winter was decreased by an average of 19% and 40%, respectively. The winter survival ratio of IRG was decreased by an average of 13% and 19%, respectively. Their dry matter yields were also reduced by an average of 8% and 19%, respectively. The heading date was different from each other in three years. The plant length at the time of IRG harvest in the spring was not significantly different among treatment groups. Taken together, our results suggest that when Italian ryegrass is grown in paddy fields by the method of ‘seeding of IRG before rice harvest’, rice should be harvested as soon as possible after sowing of IRG ‘Kowinearly’ in the autumn to increase forage productivity.

This study was conducted to evaluate the growth characteristics and dry matter yields of Italian ryegrass (Lolium multiflorum Lam., IRG) cultivars for three years (2011~2013). The cold-resistance of domestic cultivars was stronger than other foreign varieties. Among early-maturing cultivars, dry matter (DM) yield of ‘Kowinearly’ was significantly higher (8,751 kg/ha) than other cultivars (p<0.05). In medium-maturing cultivars, DM yield of ‘Kowinmaster’ and ‘Tam 90’ was 9,394 and 7,461 kg/ha, respectively. Of the two, the former’s DM yield was higher than the latter’s (p<0.05). Among late-maturing cultivars, DM yield of ‘Hwasan 104’ (9,809 kg/ha) was similar to ‘Hwasan 101’ (9,354 kg/ha), but significantly higher than the other late-maturing cultivars (p<0.05). According to the results obtained from present study, early-maturing cultivars with cold-tolerance and high productivity is required for the paddy field cultivation of an Italian ryegrass cultivar after rice harvest in Cheonan region. Medium- and late-maturing cultivars are more advantageous for the dry field cultivation of the maximum quantity that is possible. In conclusion, to select which cultivar/s to grow, the climate of the growing area, weather conditions, and the cropping system must all be considered

This study was conducted from October 2014 to May 2015 to explore forage production and feed values of Italian ryegrass, Rye and whole crop barley as winter forage crops in the Southern region of Korea. The experimental location was over 10 points for each species and each sampling point area was 1 m² (Width: 1 m × Length: 1 m). Air mean temperature and rainfall in the Southern region of Korea during the experimental period was 6.95 ± 5.75℃ and 70.45 ± 54.68 mm, respectively. Fresh forage yield of Italian ryegrass, the most cultivated forage in the Southern region of Korea, was 44.4 ± 7.0 ton/ha. The percentage of dry matter for whole crop barley was 28.9 ± 7.0%. Crude protein (CP) was higher in Italian ryegrass (10.7 ± 5.3%) while total digestible nutrient (TDN) had the highest value in whole crop barley. Crude protein was not significantly different by location. However, the neutral detergent fiber (NDF), acid detergent fiber (ADF) and total digestible nutrient value of forage from Jeonbuk province were higher than in forage from Gyeongnam province.

본 시험은 2011년부터 2013년까지 3년 동안 경북 예천 군 농가포장에서 이탈리안 라이그라스(Lolium multiflorum Lam) 국내육성 품종과 수입품종의 생육특성 및 수량성을 평가하기 위하여 실시하였다. 시험설계는 품종을 처리로 해서 조생종 6품종, 중생종 2품종, 만생종 4품종 등 모두 12처리, 난괴법 3반복으로 배치하였다. 파종은 2011년에는 9월 26일, 2012년에는 9월 25일에 실시했으며, 수확은 품 종별로 출수기에 맞추어 수확하였다. 대부분의 국내육성 품종이 도입품종에 비해 내한성이 더 강한 것으로 나타났 다. ha당 건물수량은 조생종에서는 ‘코윈어리’ 품종이 10,031 kg으로 다른 5품종보다 많았으며(p<0.05), 중만생종 에서는 ‘화산 104호’ 품종이 ‘화산 101호’ 및 ‘코윈마스터’ 품종과 비슷하였으며 다른 품종보다 건물수량이 많았다 (p<0.05). 본 연구의 결과에 의하면 중부지역에서 답리작 재배 시 ‘코윈어리’ 또는 국내육성 조생종 품종을 선택하 는 것이 유리하며, 논이 아닌 밭에서는 중만생종이 유리할 수 있을 것으로 판단된다. 따라서 품종을 선택할 때에는 재배지역의 겨울철 기온, 강수량 및 작부체계를 고려하는 것이 중요하다고 사료된다.

Early diagnoses of pregnancy for animal such as swine and bovine is extremely important to increase income of a farmhouse and for the management of farm. For the development of immunoasaay system of pregnancy in swine, we report a competitive heterologous enzyme linked immunosorbent assay (ELISA) for the direct measurement of oestrone sulfate (E1S) in diluted urine using anti-E1G (glucuronide) monoclonal antibody which cross react with E1S. The principle of assay was based on the typical solid-phase competitive ELISA methods using E1G-HRP (horseradish peroxidase) as a tracer and E1S for standard. The method had a reasonable sensitivity for the detection of E1S with 0.15 ng/ml as a detection limit. The intra-assay and inter-assay precisions were raging coefficient of from 8.50～9.67% and 8.50～9.87%, respectively, which were quite acceptable. In a field trial with a group 37 sows (18 non-pregnancy and 19 pregnancy sows) after day 29～30 post service, the concentration of E1S were determined to be below 30 ng/ml in all non-pregnancy group and over 48 ng/ml in pregnancy group except one sample. The method described here, heterologous ELISA for the measurement of E1S in urine is good enough for monitoring the early pregnancy test of swine.

Anthocyanins are the primary pigments in black, blue, and purple cereal grains. Recently, anthocyanins have been recognized as health-enhancing substances due to their antioxidant activity. Anthocyanin-pigmented barley grains can be a stable source of anthocyanins as well as β-glucan. Cloered barley as purple, blue and black barley consumptions are rapidlly growing presently due to their healthy functional food ingredients in Korea. Color barley cultivars accumulate purple pigments in the stem, awn, lemma, palea, and pericarp during seed maturation. The large consumption of barley in human foods is almost pearled products. Here we investigated composition of pearled barley and pearling by-products of korean colored barley varieties by degree of pearling. Barley grains from four hull-less colored barley varieties, Zasoojeongchal, Boseokchal Ganghochung and Huknarae were pearled to various degrees(5-50%). The composition (β -glucan, total phenol, proanthocyanidin and total anthocyanin) of pearled barley fractions flour and pearled barley grain was determined. β-glucan content was not changed seriously in pearled barley grain according to increasing pearling degree. Total phenol and proanthocyanidin content was decreased. β-glucan content was increased in pearling by-products according to increasing pearling degree and total phenol and proanthocyanidin content was decreased. Total anthocyanin content also was decreased in pearled barley fractions flour by the degree of pearling.

Current consumers have interest in nutrition and health. So, the interest in barley for other food and industrial applications is increasing. Noodles, which have been consumed largely in korea, are usually made from wheat flour, salt and appropriate amount of water. A New Six-rowed Naked Barley Cultivar “Dahan” was developed in 2012, have high winter hardness, lodging tolerance and good noodle property. It was crossed in 2001, and an elit line was selected in 2010 and designated as ‘Iksan 106’. It showed good agronomic performance in the regional yield trials (RYT) from 2010 to 2012. The average heading and maturing dates of “Dahan” were April 29 and June 3 in paddy field, which were two day earlier than those of the check cultivar ‘Saessalbori’ respectively. The new cultivar, “Dahan”, had 92cm of culm length and 3.9cm of spike length. It showed 625 spikes per m2, 54 grains per spike, 31.3 g of 1,000-grain weight, and 815 g of test weight. “Dahan” showed better resistance to BaYMV (Barley yellow mosaic virus) than those of the check cultivar. Its average yield of the pearled grain in the regional yield trial was 4.32 MT/ha in paddy field, which were 16% higher than those of the check cultivar. It showed higher breakdown and setback than those of the check cultivar. Texture properties of noodle was better in hardness, adhesiveness, chewiness. This cultivar would be suitable for the industrial application as noodle and bread.
