  • This study develops a demand and supply model and price model for Miryang sesame leaf cultivation and predicts the optimal production level to maximize total profit for Miryang sesame leaf farms. We used time series data from 1996 to 2017, which are related to Miryang sesame leaf cultivation. For the analysis, we estimated the demand function and average cost function, calculated the optimal production level and price, and derived the optimal profit. In addition, we predicted the optimal production level, price, total revenue, total cost, and profit until the year 2030 through scenario analysis. The results show that the optimal production level until the year 2030 is between 10 and 12.5 thousand tons, while the production volume was 7 thousand tons in 2017, and total profit for Miryang sesame leaf farms is estimated at 13.3 to 21.3 billion Korean won in 2030. The producer group needs to maintain the optimal production level to maximize total profit for farmers, as suggested in this study.

  • Effects of defatting on the starch gelatinization of Akibare (Japomica) and Milyang 30(J/Indica) rice and on textural properties of cooked rices were investigated. Defatting increased amylographic viscosity greater in Milyang 30 than in Akibare. Hardness of cooked rice was decreased by defatting both in Akibare and Milyang 30. The reduction of hardness, however, was more pronounced for Milyang 30 than for Akibare, by defatting.

  • The hydration of two japonica(Akibare and Milyang 15) and four indica(Milyang 30, Suweon 287, Suweon 294 and Iri 342) rice varieties was investigated in terms of mathematical rate equation. The hydration rate at temperatures of $4{\sim}32^{\circ}C$ was examined by a weighing method. The absorption of water was directly proportiponal to the square root of the hydration time(t) and was described by the diffusion equation: $1-\bar{M}=(2/\sqrt{\pi})(S/V)\;\sqrt{Dt},\;where\;\bar{M}$ is dimensionless moisture ratio, S/V is the surface-to-volume ratio and D is diffusion coefficient. The average D value was given by the Arrhenius relation: $D=D_0\;\exp(-E_a/TR)$. The activation energy was $4{\sim}5kcal/mole$. The rice samples could be classified into three groups based on hydration kinetics: Milyang 30-Suweon 287; Akibare-Milyang 15; and Suweon 294-Iri 342.

  • This study was performed to evaluate the differences in resistance of rice varieties to biotypes of the brown planthopper (BPH), capable of surving on the Milyang 30 and Milyang 63 varieties which have Bph 1 and bph 2 gene for resistance, respectively. The rice varieties tested were Milyang 30, Cheongcheong, Milyang 63 and Gaya which have been reported as having resistant genes for the BPH. The check varieties were Chucheong and Sangpoong which have no resistant gene. The degree of resistance to the BPH biotypes indicated that Milyang 30, Cheongcheong, Milyang 63 and Gaya varieties were highly resistant to the biotype 1. But their reactions against biotype 2 and 3 were variable, namely Milyang 30 and Cheongcheong were susceptible to biotype 2, and Milyang 63 was susceptible to biotype 3. In the esterase isozyme patterns of brown rice the bands of ${\beta}-1,\;{\beta}-3\;and\;{\beta}-5$ were detected in Chucheong and Sangpoong, while the bands of ${\alpha}-1,\;{\beta}-2\;and\;{\beta}-5$ were detected in the test varieties which have genes for resistance. However, the bands of ${\beta}-5$ in Milyang 63 and Gaya were stronger than those of Milyang 30 and Cheongcheong varieties. In the root of 10-days seedling, the esterase bands of ${\alpha}-2,\;{\beta}-2\;{\beta}-4\;and\;{\beta}-5$ were detected in Chucheong and Sangpoong, while the bands of ${\alpha}-1,\;{\beta}-1\;{\beta}-3\;and\;{\beta}-5$ were detected in the tested different varieties. But the bands of ${\alpha}-1\;and\;{\beta}-5$ in Milyang 63 and Gaya were stronger than those of Milyang 30 and Cheongcheong varieties.

  • This study was conducted to investigate the incidence of bacterial leaf blight (BLB) in Milyang 30 which was previously considered to be resistant to Xanthomonas campestris pv. oryzae Seeds of Milyang 30 were collected from Suweon, Milyang and Haenam. When rice plants from different source were inoculated at the maximum tillering stage and flag leaf stage, reactions of Milyang 30 were consistant. The susceptibility of Milyang 30 was found to be due to infection with tome isolates in the pathotype II of X. campestris pv. oryzae.

  • 밀가루에 멥살(밀양 23호) 또는 통일찹쌀 가루를 10, 20 및 30% 대체한 복합분의 물리적 성질 및 제빵 적성을 검토하였다. 밀-밀양 복합분은 밀-찹쌀 복합분보다 높은 점도를 보였다. 복합분의 파리 노그라프 안정성은 밀가루 보다 짧았으나 최적 반죽 발전 시간은 비슷하였다. 제빵 적성은 밀-밀양복합분이 다소 좋은 결과를 보였고 대체로 쌀가루(멥쌀 또는 찹살)를 20%수준까지는 대체할 수 있을 것으로 보인다. 10% 수준으로는 밀가루 빵에 크게 손색이 없는 제품이 가능하였다.

  • 밀양지역 지하수의 계절별 수위변동 특성을 파악하기 위하여 500여개 공을 대상으로 총3회 측정하였다. 봄에서 늦가을까지의 시기별로 측정된 현장지하수위 자료를 이용하여 밀양시 전역의 충적층 및 암반 대수층의 지하수위 등치선도를 작성하였다. 지구통계기법을 이용하여 작성된 밀양지역의 지하수위 등치선도는 계절별로는 큰 변동이 없었으나, 충적대수층과 암반대수층에서의 지하수위 분포양상은 다르게 나타났다. 계절적인 지하수위 변동이 약한 것은 밀양지역의 지하구는 대부분이 농업용수로 이용되고 봄과 가을에는 용수 사용량이 비슷하며, 여름에는 강수량은 맑지만 농업용수의 사용량이 증가하여 함양량이 크지 않기 때문이다. 대수층유형에 따른 지하수위는 암반대수층의 피압 정도와 충적 및 암반 지하수공들의 공간적인 분포 양상에 따라서 영향을 받고 있는 것으로 나타났다.

  • The hydration and cooking rate of two rice varieties, Akibare (Japonica) and Milyang 23 (Indica), were investigated in terms of mathematical rate equations. The hydration rate at temperatures of $10{\sim}40^{\circ}C$ was examined by weighing method. The absorption of liquid water by rice grain was directly proportional to the square root of the hydration time. The diffusion coefficient was given by the Arrhenius relation : $D=3.151{\times}10^{-3}\exp\;(-4000/RT)$ for Akibare and $D=5.853{\times}10^{-3}\exp\;(-5700/RT)$ for Milyang 23. Milyang 23 was cooked at a faster rate than Akibare. The activation energies for cooking were in the range of 18 000 cal/mole at $90{\sim}100^{\circ}C$ and 9,000cal/mole at $100{\sim}120^{\circ}C$. However, Milyang 23 showed slightly higher activation energy of cooking at $90{\sim}100^{\circ}C$. Adhesiveness and amylograph viscosities at all reference points for Milyang 23 were higher than those for Akibare.
