본 시험은 경흔적수 측정법으로 수삼의 연근을 판별하기 위하여, 4, 5, 6년근의 경흔적수 발생실태를 조사하였다. 경흔적수를 이용한 연근판별법은 3년근 경흔적부터 식별가능하여 경흔적수에 2를 더하면 년근판별이 가능하였다. 년근별 경흔적수가 4년생에서 2개 발생율이 89.5%, 5년생에서 3개 발생율이 79.7% 6년생에서 4개 발생율이 46.3%로, 4, 5년근의 판별은 가능하였으나, 6년근 판별은 정확도가 낮아 보조자료로 활용함이 타당하였다. 경흔적을 이용한 연근 판별의 제한요인으로 뇌두파손과 다경발생임을 확인하였고, 뇌두파손율과 다경발생율은 년근이 증가함에 따라 증가되었다. This experiment was conducted to find identification of ginseng root's age using the number of stem vestiges in rhizome. The number of stem vestiges in rhizome is a useful key to confirm the age of ginseng root as follow : 4-year-old root has two, 5-year-old root has three, 6-year-old root has four. The distribution of stem vestiges in rhizome each year root are as follow : 2 stem vestiges in 4-year-old root is 89.5%, 3 stem vestiges in 5-year-old root is 79.7%, 4 stem vestiges in 6-year-old root is 46.3%. However, the limiting factors of identification of ginseng root's age using the number of stem vestiges in rhizome is appearance of multi-stem per plant and appearance of destroyed stem vestige in rhizome. The ratio of appearance of multi-stem per plant and destroyed stem vestige in rhizome are increased according to root age.

Pesticides persisted in soil environment may be subjected to the unexpected uptake by plant root. As these absorbed pesticides can result eventually in safety problems to agricultural products, it is required to predict the plant uptake extent of soil-persisting pesticides inadvance. One of the previous prediction methods is to assess the uptake extent using a mathematical model. When developing the plant uptake model of soil-persisting pesticides, adsorption and dissipation interactions between pesticides and soil may be parameters that play major roles in determining the uptake extent into plant. With considerations of parameters relative to these interactions, we developed a chemical-specific residue (CSR) model, Ce(t)=C0·(1/2)t/T/Kd, in order to predict the residual patterns of endosulfan isomers ( - and  -) in soils containing different organic matter contents. The adsorption (Kd) and dissipation (T) parameters were obtained from indoor experiments, and the applicability of CSR model was assessed by comparing between experimental measurements and modeled estimates. The Kd and T values were significantly varied depending on organic matter contents in the tested soils. For the low organic matter-containing soil, the Kd and T values of the  -isomer were 50.2 mL g-1 and 16 d, respectively; the values of the  -isomer were 54.4 mL g-1 and 231 d, respectively. On the other hand, for the high organic matter-containing soil, the Kd values were 377.4 mL g-1 for the  -isomer and 407.4 mL g-1 for the  -isomer, and the T values for the  - and  -isomers were 139 and 347 d, respectively. Using these parameter values, the modeled values were in good agreement with the measured values with standard errors of less than 23.5%. Therefore, the developed CSR model may be used as a tool for predicting the residual amount of endosulfan in soil.

국내 육성 검정콩을 대상으로 고위도의 수원 (37°16`N)과 저위도의 밀양 (35°30`N)에서 단순 재배지역 차이의 관점이 아니라, 작물의 생육환경에 영향을 줄 수 있는 위도 차이의 관점에서 검정콩 함유 안토시아닌 및 이소플라본의 함량 변이를 검토한 결과 안토시아닌 중 D3G 함량은 검정콩 3호 및 일품검정콩이, C3G 함량은 밀양 113호가, Pt3G 함량은 밀양 113호 및 일품검정콩이, 총 안토시아닌 함량은 밀양 113호가 가장 높았다. 재배지 위도차이에 따른 안토시아닌 함량변이에서는 검정콩 3호는 D3G, C3G, 및 총 안토시아닌 함량이, 일품검정콩은 C3G 및 총 안토시아닌 함량이 고위도에서 저위도보다 높은 양상을 나타내었다. 이소플라본 함량은 검정콩 4호가 가장 높았고, 재배지 위도차이에 따른 이소플라본 함량 중 daidzein은 검정콩 3호, 밀양 112, 및 밀양 113호가 고위도에서 저위도보다 높았으며, glycitein은 검정콩 3호, 4호가 고위도에서, 밀양 113호는 저위도에서 높았다. Genistein은 공시된 검정콩 중 밀양 113호를 제외한 대부분 품종 및 계통이, 총 이소플라본 함량은 검정콩 4호와 청자콩이 저위도에서 고위도보다 높았다. 그리고 Pt3G를 제외한 안토시아닌 및 이소플라본 함량은 위도에 따른 재배지역과 품종 및 계통 간 상호작용이 있어 품종 및 계통에 따라 위도별 재배환경이 영향을 미치는 것으로 판단된다. This experiment was conducted to investigate the variation of anthocyanin, and isoflavone contents in five cultivars and two lines of Korean domestic black soybeans grown at different latitudinal locations, a high latitude, Suwon (37°16`N) and a low latitude, Milyang (35°30`N). Delphinidin-3-glucoside (D3G) contents of anthocyanin in Geomjeongkong # 3 and Ilpumgeomjeongkong, cyanidin-3-glucoside (C3G) content in Milyang # 113, petunidin-3-glucoside (Pt3G) contents in Milyang # 113, and Ilpumgeomjeongkong, and total anthocyanins in Milyang # 113 were highest among the seven black soybean cultivars and lines. D3G, C3G, and total anthocyanins in Geomjeongkong # 3, C3G, and total anthocyanins in Ilpumgeomjeongkong grown at high latitude were higher compared to low latitude. Daidzein, glycitein, genistein, and total isoflavone contents in Geomjeongkong # 4 were highest among the seven cultivars and lines. Daidzein contents of isoflavone in Geomjeongkong # 3, Milyang # 112, and Milyang # 113 grown at high latitude were higher compared to low latitude. Glycitein contents in Geomjeongkong # 3, and # 4 grown at high latitude were higher compared to low latitude, while it in Milyang # 113 grown at low latitude was higher compared to high latitude. Genistein contents in most black soybeans except Milyang # 113, and total isoflavone contents in Geomjeongkong # 4 and Cheongjakong grown at low latitude were higher compared to high latitude. The variations of anthocyanin except Pt3G and isoflavone contents seemed to be affected by environmental conditions like different latitude than the genotype because they showed the significant interaction between cultivars and locations.

This experiment was conducted to determine economic application method of Yakto among 6 application method: amount of Yakto application 3 plots(70ℓ, 25.5ℓ, 13.3 ℓ/kan), and added side dressing(3ℓ/kan) each plot. The reduced Yakto application(25.5ℓ/kan) with side dressing(3ℓ/kan) showed similar root diameter, fresh weight of roots and yield of good seedlings to standard Yakto application(70ℓ/kan). And also this application method of Yakto gave similar content of Ca and Mg, but the lower content of N, P, K in roots to standard Yakto application(70ℓ/kan). These suggested that 25.5ℓ Yakto application added side dressing(3ℓ/kan) per kan might be economical application method of Yakto.

본 연구는 갈조류인 다시마, 모자반, 톳을 효소적 방법으로 가수분해하여 이를 이용한 바이오 에탄올 생산 가능성을 확인하고자 하였다. 가수분해 효소 분리 및 바이오 에탄올 생산 실험 결과는 다음과 같이 요약할 수 있다. 효소는 해수 및 채취한 갈조류 시료에서 분리하였으며, 갈조류의 주요 다당류인 alginate와 laminaran에 대한 효소활성을 측정하였다. 또한 다시마, 모자반, 톳에 대한 직접적인 갈조류 가수분해 효과를 확인 하였다. 조효소에 의한 가수분해는 alginate에서 특히 높게 나타났으며, laminaran에서도 일부 활성을 보였다. 갈조류의 전처리에서 환원당의 생성은 외분비 효소와 전체 조효소에서 크게 차이가 없었으며, 기질로는 다시마에서 최대 1.90 g/L로 가장 높게 확인되었다. 모자반과 톳에서의 가수분해가 12 h 안에 완료되는 것에 비해 다시마는 72 h 동안 반응이 지속적으로 일어났다. 에탄올 발효는 환원당 생성량과는 무관하게 나타났는데 이는 전처리 방법에 따라 갈조류 다당류의 가수분해에 미치는 영향이 다르기 때문으로 생각되며, 또한 전처리 과정에서 생성되는 부산물이 영향을 미치기 때문인 것으로 생각된다. 갈조류 에탄올 발효에서 기질로 다시마를 이용했을 때 에탄올 생산 수율이 가장 높았다. 다시마를 이용한 발효에서는 발효균주 및 효소처리에 따른 에탄올 생산량이 대략 0.90 g/L로 유사하게 나왔다. 모자반에서의 에탄올 생산은 발효균주를 Saccharomyces cerevisiae로 하였을 때 최대 0.14 g/L로 확인 되었으며, 톳에서는 Saccharomyces cerevisiae를 이용한 발효에서 에탄올생산이 전혀 확인되지 않았으며, Pachysolen tannophilus 에서만 0.09 g/L의 에탄올 생산이 생산되었다. The Brown-algae polysaccharide consisting of alginate and laminaran is usable as high bio-ethanol production if hydrolyzed to monomer unit. The objective of this study is to produce bio-ethanol from brown-algae using enzymatic saccharification. Bio-ethanol was produced by Saccharomyces cerevisiae KCCM 1129 and Pachysolen tannophilus KCTC 7937 strains. The substrate used Laminaria japonica, Sargassum fulvellum and Hizikia fusiformis. We isolated a new alginate lyase and laminaran lyase producing microorganism for hydrolysis of brown-algae from southern sea of Gijang. The reducing sugar was obtained 1.90 g/L from Laminarin japonica 20 g/L that used enzyme from Bacterium antarctica. In pretreatment of the most suitable brown-algae for ethanol production, ethanol concentration of 0.93 g/L and yield of 4.65% were obtained in condition of Laminaria japonica in medium.

In this study, the effect of probiotic supplementation on growth performance, blood metabolites, and meat quality of Hanwoo steer was investigated. A total of 32 Hanwoo steers (15-17 months, average body weight 462±37.9 kg) were randomly allotted to 4 dietary treatments (0, 0.5, 1.0, and 1.5% mixed probiotics), with four Hanwoo steers per pen (two replicates per treatments), and reared for 12 months. There were no differences among treatments in growth performance of Hanwoo steer (P>0.05); however, feed intake decreased linearly with increasing levels of mixed probiotics. Growth hormone and Blood Urea Nitrogen (BUN) levels responded linearly with increasing levels of dietary mixed probiotics (P<0.05), but not insulin and blood glucose did not. In particular, total cholesterol was significantly lower for the 1% mixed probiotic treatment in comparison with that of the other treatments (P<0.05). The pH, Thiobarbituric Acid Reactive Substances (TBARS), cooking loss, and meat color were influenced by increasing levels of mixed probiotics (P<0.05), but the carcass characteristics and shear force were not. Regarding sensory evaluation, the addition of mixed probiotics resulted in significant difference in meat color, tenderness, aroma, off-flavor, juiciness, and marbling score, but not in overall acceptability. In addition, fatty acid profiles indicated no differences between control and mixed probiotic treatments. In conclusion, mixed probiotic treatment at 1% levels can enhance consumer preferences possibly by reducing cholesterol and TBARS.
