To increase dyeability of cotton fabric to the chestnut shell dyeing, we had several dyeing experiments with the experimental fabrics which was pre-treated by soybean, NaOH, KOH. Three kinds of experimental cotton fabrics were used and chestnut shell dyebath was made for the experiment. Munsell's color HV/C and color differences ΔE of dyeing fabrics were compared between pre-treatment and none pre-treatment dyeing fabrics. The main results were as follows ; Color differences of dyeing fabrics pre-treated with soybean, NaOH, KOH were higher than those of none pre-treated dyeing fabrics. In case of pre-treatment with soybean, the concentration of the soybean bath affected the color differences but not affected in case of pre-treatment with NaOH & KOH. Munsell's color of pre-treatment fabrics with soybean, NaOH, KOH were same with the none pre-treatment fabrics. Colorfastness of the pre-treated fabrics were same degree, but only in case of soybean pre-treated fabrics were low in fastness of washing(change) & perspiration(acidic change).

본 시험은 1980년도에 전남대학교 시험포장에서 수행된 것으로서, Metribuzin의 처리시기에 따른 품종반응차이를 알기 위하여 광교외의 5대두품종과 Pre-sowing 외에 4처리 시기를 공시하여 작물의 초기생육반응을 조사하여 다음의 결과를 얻었다. 1. 공시품종내에서는 약제에 대한 저항성 차이가 뚜렷하지 않았다. 2. 품종차이보다는 약제처리시기에 따른 반응차이가 헌저하였으며, 대부분 대두품종의 저항성 크기는 E. Post-emg.< L.Post-emg $\ll$re-sowing=Control의 순으로 컸다. 3. Metribuzin의 약해 Symptom은 주당엽수 < 초장 $\ll$주당분지수의 순으로 뚜렷한 감소를 보이는 특징이었다. 4. 우리나라 대두품종에 대한 Metribuzin의 사용은 Pre-sowing이나 Pre-emg.가 추천되며, 특히 Pre-sowing에 대한 토양혼화법 연구와 단제보다는 혼용처리의 이점을 찾을 필요가 있다.

In attempt to avoid crop damage through wild bird's picking, this study was designed with aim to evaluate several pre-sowing soybean seed coatings for optimum yield in corn-soybean mixed forage. It was investigated under four cropping treatments, viz. 1) corn sole, 2) corn mixed with soybean without any coating, 3) corn with iron coated soybean and 4) corn with thiram coated soybean. Each treatment had three replicates and corn sole was control treatment. Pioneer (P1184) and crossbred ($PI483463{\times}Hutcheson$) seeds were used for corn and soybean, respectively. The trial was conducted under randomized block design from $5^{th}$ June to $23^{rd}$ September, 2015. Data were an alyzed through ANOVA technique using SAS9.1.3 software. Results depicted that survivability of soybean against wild birds damage was found better (p<0.05) in thiram coating which was higher than iron coating and control treatment but later on thiram coating had adverse effects on subsequent growth of soybean plants. Corn stalk height was decreased (p<0.05) in thiram coating, whereas corn ear height was reduced in iron coating treatment. Iron coating enhanced (p<0.05) height of soybean plant (p<0.05) better than that of thiram coating. Soybean seed coatings didn't influence dry matter yield and nutritive value in terms of total digestible nutrients yield in corn soybean mixed forage. Conclusively, although presowing thiram coating enhanced survivability of soybean plants against wild bird damage but had adverse effects on its subsequent growth. However, soybean seed coatings didn't influence yield and nutritive value of corn soybean intercropping forage.

Reproduction of the soybean cyst nematode (SCN), Heterodera glycines Ichinohe on the susceptible soybean cultivar, Lee 74, was significantly reduced by pre-, post- and simultaneous treatments of acetylsalicylic acid (ASA, aspirin). The control efficiencies were 60%, 64% and 87% for pre-, post- and simultaneous treatments, respectively. ASA had no significant effect on the survival of 2nd stage juveniles and their penetration into the soybean root tissues, but significantly inhibited the early stage nematode growth in the roots. Syncytia were formed 2∼3 days after inoculation in the susceptible soybean without ASA treatment, characterized by dense cytoplasm and increased cellular organelles such as mitochondria and endoplasmic reticulum. The nematode stylet was penetrated into the syncytial cell, and feeding tube was formed at the nematode stylet was penetrated into the syncytial cell, and feeding tube was formed at the nematode stylet entry. However, in the ASA treatments, syncytium was not formed or degenerated, depending on the root tissues. In the pre-treatments of ASA, nematode stylets did not penetrate into cells, showing callose-like cell wall thickening formed at the nematode probing sites, or retracted from the infected cells. The stylet penetration sites of syncytial cells appeared to be sealed off with fibrillar materials. With post-treatment of ASA, syncytia formed by the nematode were degenerated, characterized by degradation of syncytial cytoplasm.

In this study, we evaluated the physicochemical and sensorial properties of frozen Hanwoo beef patties prepared from prerigor and post-rigor muscle with soybean sauce or sodium chloride. The pH of the soybean sauce treatments was lower than the sodium chloride treatments (p<0.05); however, the Hanwoo patty prepared from pre-rigor muscle with soybean sauce had a lower cooking loss and smaller diameter than the Hanwoo patty prepared under the same conditions from post-rigor muscle (p<0.05). The addition of the soybean sauce inhibited lipid oxidation due to the antioxidative materials in soybean sauce such as melanoidin. The hardness of patties prepared from pre-rigor treatment was lower relative to those prepared from post-rigor muscle (p<0.05); however, there was no significant difference between springiness, cohesiveness, and chewiness (p>0.05). In the sensory evaluation, patties prepared from pre-rigor muscle with soybean sauce had a significantly high score in all traits (p<0.05); thus, pre-rigor muscle with soybean had the highest overall acceptability. Furthermore, the addition of soybean sauce to pre-rigor muscle produced similar effects as those observed for the addition of sodium chloride in regards to psychochemical properties. Moreover, meat products produced from pre-rigor muscle will have better antioxidative and sensorial properties.

This study investigated the effects of the working mechanisms of proteins, mordants, and dyes, as well as the mordanting order, on dye uptake by silk fabric pre-treated with proteins and dyed with freeze-dried sappan wood water extract. Soybean protein and sodium caseinate were used as the proteins. 1. When Al mordants were not used, the dyeability of the fabrics increased upon protein pre-treatment as compared to the case without treatment. 2. Dyeing with protein pre-treatment, followed by mordanting, led to the highest dye uptake, and the optimal protein concentration was 5%. 3. The K/S values slightly decreased with an increase in the dyeing temperature, and the fabric turned dark red in color when dyeing was carried out at increasing temperature. Fabrics showed the highest dye uptake at $40^{\circ}C$. 4. Regarding the effect of time, the K/S values of the fabrics with and without protein treatment showed almost no increase after the initial dyeing time of 10min; further, there was hardly any difference in the cases with and without protein pre-treatment. 5. In case of protein pre-treatment fabrics, the washing fastness was level 2. The dry cleaning fastness showed very excellent result with level 4-5. The rubbing fastness was better in dry rubbing than in wet rubbing of the fabrics. For the light fastness, all dyed fabrics showed low fastness.
