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.

Purpose : The purpose of this study were to examine the degree of job duty importance and difficulty of nutrition teachers in elementary school and then to make their future duties and roles clearly. Methods : The duties of nutrition teachers were classified into four fields such as foodservice management, nutrition education, nutrition counseling and educational experience of Korean agricultural products, and then each field were divided into job duties and job tasks. The subjects was 139 dietitians at elementary schools in Dague and Kyungpook Province who appraised the degree of importance and difficulty of the above four job duties with the Likert 5-point scale through a questionnaire survey. Results : From the results of the survey, it was found that every dietitian had highly assessed the importance of the four job duties of nutrition teachers. In a survey of the degree of job duty importance and difficulty on the dietitians, subjects recognized the following such as haccp management in the field of foodservice management is of the most importance(4.30), and the personal management has the most difficulty (3.80). In the field of nutrition education, the work of establishment nutrition education plan is of the most importance(4.33), and the developing of nutrition education materials and programsn are the most difficulty (4.13). In the field of nutrition counselling, students of that than parents and teachers counselling is of the most importance (4.15) and the most difficulty (4.08). Finally, in the field of our agricultural products experience education, which of he work is the most importance(4.07), and difficulty (4.02). Conclusion : Therefore, it is judged that nutrition teachers in the future should not only have a foodservice management, as their main job duty, but also aid in constructing life-long health management system for students and teachers by conducting a nutrition education and counseling, and also exert their energies in the job duties of menu development and experience education utilizing our agricultural products.

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.

The purpose of this paper is suggest teaching methods for historical data lesson in elementary history classrooms. Historical data as a source of historical knowledge have interpretive and controversial characteri-stics in themselves. It is, therefore, important that students exchange their ideas each other over the data and seek for implications in them, since this is part of being democratic citizens. Before teachers practise this kind of instruction step by step, students should have some understanding a priory what historical data are. This paper suggests some instructional contexts for teachers which may help children understand what historical data are and what characteristics they have. Children are expected to develop historical sense of data more effectively by trying historical generalization and historical imagination.

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.

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.
