우리나라는 일찍이 농경문화의 정착으로 특히 곡류를 이용한 다양한 음식문화가 형성되었고 그 가운데 전통 한과류는 세계적으로 차별화된 독창성을 가지고 현재에 이르게 되었다. 그러나 이러한 독창성을 지녔음에도 불구하고 시대적 요청인 현대화와 서구화에 밀려 그 수요가 줄게 되었고 또한 계승노력의 부족으로 일부는 없어졌으며 극히 한정된 지역이나 가정에서 전수되어 그 명맥을 간신히 유지하고 있는 실정이다. 따라서 본 연구에서 한과류 가운데 활용 가능성 높은 형태인 다식에 신소재인 실크펩타이드를 첨가하여 제조하였으며, 쌀다식의 영양성분 및 관능평가에 대한 요약 및 결론은 다음과 같다. 1. 일반성분 분석결과에서 실크펩타이드 분말 첨가비율이 증가할수록 쌀다식의 조단백질 및 조회분 함량이 대조군에 비해 유의하게(p<0.05) 증가 되었다. 2. 무기질 함량은 실크펩타이드 분말 첨가비율이 증가할수록 칼슘, 마그네슘 및 칼륨함량이 유의적(p<0.05)으로 증가되었다. 3. 실크펩타이드 분말 첨가비율에 따른 쌀다식의 관능평가 결과 2% 첨가군이 대조군이나 1%, 3%, 4% 첨가군에 비해 맛 등이 좋은 것으로 나타났다. 본 연구를 통해 개발된 실크펩타이드 분말이 첨가된 기능성 쌀다식을 기초로 다양한 실크펩타이드 첨가 식품이 개발되어 좋은 아미노산 공급원이되기를 기대한다.

To examine sediment characteristics and find anthropogenic effects on riverine wetland ecosystems, paleoecological study was carried out at Bam islands in Seoul. Three hundred cm deep sediment cores were retrieved and dated with the lamination analysis method until 36 cm depth (1986). Sediments were divided into three zones based on the depth profiles of physico-chemical variables: below 160 cm depth (before 1968), between 160 and 40cm depths and above 40cm depth (after 1986). Physico-chemical characteristics were very variable between 160 and 40cm depths and this indicates unstable sedimentation environment. Even though heavy metal concentrations were relatively low, Cd and As contents have increased continuously. Dry mass accumulation rates during $1968{\sim}1986\;and\;1987{\sim}2003$ were 140 and $21\;kg\;m^{-2}\;yr^{-1}$, respectively. This was related to flooding intensity and duration. Bulk density, water content, loss on ignition, N, C, C/N ratio were very similar to other river delta but Ca, Na and K contents were 2 to 4 times higher than others. Heavy metal contents except Pb were lower or similar to those in other studied marshes in Korea. Heavy metal and Mg contents were correlated with each other and this suggests that the source of heavy metals be parent rock. From $^{13}C$ dating dates of organic materials in sediment, it is suggested that organic matter originated from the watershed and flooding intensity in the watershed might be responsible for the source of sediments. This study provides reference data for the comparison of sediment characteristics at islands in river and for the management of Bam islands.

The quality of silages, made from whole crop barley, rye, spring oat, Italian ryeglass, orchardgrass, alfalfa and grass-legume pasture mixtures, were evaluated under two different conservation techniques in baled silage making (BS) and conventional silages(CS). Crops materials were harvested at the stage of the greatest dry matter accumulation(hard dough for barley, soft dough for rye and oat, late bloom for Italian ryegrass and others pasture species), and baled in a self constructed square baling chamber weighted by 25~30kg in dry matter basis. Each bales were wrapped with 0.05mm thick polyethylen plastic film and stored six months long in stack silos. Barley, rye, oat and Italian ryegrass including of pasture crops produced higher quality silages in the baled silage making, due to better organic acid fermentation and lower nutrient losses during the period of storage than those in the conventional silages. TDN contents of barley silages were 65.3% in BS and 63.7% in CS, NEL value of barley silages was improved hum 6.48MJ(CS) to 6.61MJ/kg(BS) in dry matter basis. Silage quality of rye, oat and pasture crops were also improved markedly in the baled silage utilization.

Radish is a common vegetable consumed in Korea, Japan, and China. Radish Breeding has been conducted based on morphological properties, such as shape and color. Recently, physicochemical properties of radish are attracting more attention from breeders to develop cultivars for the retail market. In this study, major components of radish were determined and their relationship with textural property analyzed. Sixty-six radish cultivars were selected and divided into white head (WH) and green head (GH) according to their head color. The cutting forces of GH and WH groups were $2.17{\pm}0.34kg$ and $2.31{\pm}0.36kg$, respectively (P > 0.05). The starch contents of GH and WH were $3.75{\pm}0.39g\;per\;100g$ (dry basis) and $4.24{\pm}0.62g$, respectively. Cellulose contents in both groups were similar at 12.3-12.4 g per 100 g (dry basis). Pearson correlation coefficients between cutting force, cellulose content, and starch content ranged from -0.33-0.326 which does not demonstrate any strong correlation between these components. Therefore, no relationship was found between the cutting force and the starch content or the cellulose content for the cultivars analyzed in this study. As the first intensive study on the texture and the major components of radish, these results could provide valuable information for radish breeding if further studies on taste and nutrient components are conducted.

This experiment was carried out to study the influence of temperature on the growth rate and nutrient uptake of tobacco seedlings grown on neutralized charcoal bed during temporary transplanting. The highest growth rate was obtained at tile temperature of 26-22-$l8^{\circ}C$, probably due to fast establishment of roots in the soil. Seedling growth was better in neutralized charcoal bed than in chaffy charcoal bed at each temperature. Days required for fresh weight to reach 20g/10p1ants were shortened by 9~12days as the temperature increased from 18-14-$l0^{\circ}C$ to 26-22-$l8^{\circ}C$. Compared with chaffy charcoal bed, days required for fresh weight to reach 20g/10 plants with neutralized charcoal bed were shortened by about 5 days, 4 days, and 2days at 18-14-$l0^{\circ}C$, 22-18-$l4^{\circ}C$, and 26-22-$l8^{\circ}C$, respectively. Three macronutrient (N, $P_2O_5,\;K_2O$) contents in seedlings increased with increase of temperature. At each temperature, N and $K_2O$ contents in seedlings of neutralized charcoal bed was higher than those of chaffy charcoal bed, whereas that of $P_2O_5$ was low conversely. Nitrate nitrogen from nitric acid that was used to neutralize chaffy charcoal was maintained to tile end of seedling period, providing the source of nitrate nitrogen for the better seedlings.

Hydroponic cultivation is a technology of raising crops without use of soil. Generally farmers use the method of DFT(deep flow technology)to grow leafy or fruity vegetables; however, systematic and scientific researches are insufficient on this matter. This study investigated the possibility of cultivating Chinese cabbage steadily year long by using the method of DFT. Chinese cabbage was cultivated hydroponically with and without Ge addition, used to prepare kimchi, and the chemical and microbiological characteristics of kimchi were compared. The basic hydroponic cultivation condition was as follows: 30 days after seeding, the raised seeds were moved to a hydroponic bed and given underground water for 3 days so the roots grow normally Standard nutrient solution was provided and the early electric conductivity concentration was maintained between 1.5∼2.5 thickness. The temperature of the solution was maintained between 10 ∼25$^{\circ}C$ to allow the growth of Chinese cabbage. When soil-cultivated, organically cultivated and hydroponically cultivated Chinese cabbages were compared, hydroponically cultivated cabbages were smaller in size and showed less ability to build up and fold leaves into a head, but showed better quality than organically cultivated cabbages. The contents of protein and fat showed no significant differences. The contents of water. Ca, P, Fe, Vitamin A and Niacin were higher in control and Ge-added cabbages compared with soil-grown cabbage. There was no difference between soil-cultivated Chinese cabbage kimchi and hydroponically cultivated Chinese cabbage kimchi.

This study evaluated the evaluate nutrient knowledge of child care teachers and assessed the nutritional level of snacks served in 18 child care centers in Tean-Gun. The survey sample was 18 child care teachers working in 18 child care centers of Tean-Gun. The questionnaire requested information about demographic factors, nutritional knowledge, management status of snacks, and the kinds and serving size of snacks served for 1 week. Data were analyzed using SPSS for windows(version 12.0) and nutritional values were assessed using Can-pro 2.0. The mean score of teachers' nutritional knowledge was 22 out of 30 points. The scores were low in the questions regarding the ease with which Ca and re deficiencies can be developed in infants. The contents of most nutrients supplied from the snacks exceeded 15% of RI(Recommended Intake) but there were significant differences in the contents of energy (p<0.05), protein (p<0.05), fat (p<0.05), carbohydrate (p<0.05) and calcium (p<0.001) between the child care centers. Especially, the difference of calcium between the child care centers was 344.84 mg. These results indicate that a program of relevant nutritional education focusing on snacks needs to be developed for child care teachers, with a special recognition on correct calcium level.
