This study was designed to develop dish recipes using Heatsun sprouts to improve the sprouts' utilization and consumption. We created four kinds of dishes with Heatsun sprouts, including Acanthopanacis cortex, Kalopanax pictus, Aralia elata, and Cedrela sinensis, and analyzed their sensory properties and nutrients. In the sensory evaluation, the overall preference for all the dishes was scored higher than 3.0, Unnaumsun-dakgoginaengchae had the highest score (4.48) among the dishes. Unnamusun-dakgoginaengchae contained higher values of protein; vitamin A, E, and B6; and folic acid than the recommended dietary allowances (RDAs). The recipe for Dureupgokgammuchim was created to reduce the bitterness and the astringent taste of Aralia elata, and it was rich in vitamin C, E, and B6, as well as in folic acid and iron. Ogapisunkkonchijolim was cooked to reduce the fishy smell of a saury with the addition of Acanthopanacis cortex. It contained 1.5 times the protein RDAs, and high levels of antioxidant vitamins, including vitamin A, C, and E. Chamjugmandu was made by the mixing tofu and various vegetables without adding meat. It had the highest calorie count among the dishes, and its vitamin A, C, and E contents were higher than the corresponding RDAs.

When it comes to a country's traditional ideas. that country's geographic setting and religious thought show the people's consciousness, and the characteristics of historic sites and relics show their cultural aspects. Our country has 5000-year cultural history. Especially, the Baekje cultural history created very remarkable relics in our history. With regard to Baekje's own patterns and workmanship, their ornaments were more focused on the beauty of soft and voluptuous curves than that of Goguryeo and Silla This study researched design characteristics of ornaments and symbolic aspects of the patterns by focusing on crowns, crowns' accessories, earrings, necklaces, chignon ornaments of the Baekje's ornaments, To put emphasis on Baekje's ornaments by comparing Baekje's ornaments with Goguryeo's and Silla's. This study collected data on Baekje's ornaments, and reviewed domestic references and specialty publications at the Buyeo National Museum, Gong-ju National Museum, home and abroad, and studied the images of Baekje's metal crafts and patterns through theses. Baekje had splendid and glorious artistic culture, but there are not many historical data and supportive relics left these days. Therefore, a lot of attention, researches and development on Baekje culture are needed. This study found that the ornaments of the Baekje era have not only ornament functions but also the people's creative mind. The culture contents in recent technological development and industrialization change people's recognition, and now they have interest in Baekje culture. Therefore, the purpose of this study is to widely popularize Baekje by studying the patterns of the Baekje era more and developing various and new designs.

Milk urea nitrogen (MUN) determination is being used an indicator of the protein-energy balance in dairy herds. A faulty balance can be corrected to optimize milk production and animal health. This parameter is regarded as a potential tool to evaluate suboptimal feeding practices and reproductive disorders. Therefore, the purpose of this study was to investigate the response of milk composition by regular feeding analysis and to compared the relationship between MUN and milk protein(MP) and fertility at the insemination period in Holstein dairy cows. Total of 355 artificial insemination (AI) for 150 Holstein cows in the herd were used to examine the relationship between MUN and MP content and conception rate. The AI occured for the cows 50 to 150 day in milk, and MUN and MP concentration were determined using automated infrared procedures. The mean${\pm}$standard deviation of MUN and MP concentration in the herd were $15.6{\pm}2.1mg/dl$ and $3.23{\pm}0.38%$, respectively. MUN contents of bulk milk were increase by elevated crude protein intake. The conception rate was lower in the cows in which the level of MUN was lower than > 8.0mg/dl (10.0%) or > higher than 25mg/dl (15.4%) relative to the cows in MUN content of 12.0~17.9 mg/dl (36.7%) at the time of insemination. Also, lower MP than 3.0% or higher MP than 3.25% were associated with a lower conception rates. Consequently, MUN and MP analyses may be used serve as a monitoring tool of protein and energy nutritional balance to improve reproduction efficiency in Holstein dairy cows.

Endophytic fungi are little known for their role in gibberellins (GAs) synthesis and abiotic stress resistance in crop plants. We isolated 10 endophytes from the roots of field-grown soybean and screened their culture filtrates (CF) on the GAs biosynthesis mutant rice line - Waito-C. CF bioassay showed that endophyte GMH-1B significantly promoted the growth of Waito-C compared with controls. GMH-1B was identified as Penicillium minioluteum LHL09 on the basis of ITS regions rDNA sequence homology and phylogenetic analyses. GC/MS-SIM analysis of CF of P. minioluteum revealed the presence of bioactive $GA_4$ and $GA_7$. In endophyte-soybean plant interaction, P. minioluteum association significantly promoted growth characteristics (shoot length, shoot fresh and dry biomasses, chlorophyll content, and leaf area) and nitrogen assimilation, with and without sodium chloride (NaCl)-induced salinity (70 and 140 mM) stress, as compared with control. Field-emission scanning electron microcopy showed active colonization of endophyte with host plants before and after stress treatments. In response to salinity stress, low endogenous abscisic acid and high salicylic acid accumulation in endophyte-associated plants elucidated the stress mitigation by P. minioluteum. The endophytic fungal symbiosis of P. minioluteum also increased the daidzein and genistein contents in the soybean as compared with control plants, under salt stress. Thus, P. minioluteum ameliorated the adverse effects of abiotic salinity stress and rescued soybean plant growth by influencing biosynthesis of the plant's hormones and flavonoids.
