The solid carbon dioxide used for prolongation shelf life of radish sprout that was just 7days. The developed equipment for treated carbon dioxide consisted of solid carbon dioxide evaporated part and high carbon dioxide and low temperature treated part that can hold products. The inner temperature of equipment decreased temperature to below $5^{\circ}C$ from room temperature for 10minutes and carbon dioxide concentration increased to 80%. The radish sprouts treated 4 different conditions that was nontreated condition (control), solid carbon dioxide put into package (CO2-1), solid carbon dioxide treated before storage using the developed equipment (CO2-2), solid carbon dioxide treated before storage and during storage, and sprout packaged with solid carbon dioxide (CO2-3). These radish sprout packaged with $25{\mu}m$ ceramic film stored at $8^{\circ}C$. The high carbon dioxide treatment did not affect the fresh weight loss. The carbon dioxide and oxygen content in package changed 40% and 10%, respectively in CO2-1 and CO2-2 at 1day after treatments. But carbon dioxide content of all treatments was decreased to 5% and stabilized. The high carbon dioxide showed the effect of reduction ethylene production, but did not affect to visual quality and offodor.

This study examined the irradiation effect of high energy x-rays on the growth of sprout plants seeds. particularly with regard to acidity, salinity and sugar content change. The experimental groups were one day old sprout plants seeds irradiated with 6MV x-rays at doses of 2, 5, 8, 10 Gy using a linear accelerator. The control group was not irradiated. After two weeks, sprout plants were grown and harvested for component analysis. The acidity of the x-ray irradiated radish and red radish groups were significantly higher than that of the control group and bok choi and buckwheat groups lower than that of the control group. The salinity and sugar content of the x-ray irradiated 5 groups were significantly lower than that of the control group and Soybean and Red radish groups higher than that of the control group. The cause of plants component change were estimated to have occurred by generate basic ions and radiation sensitivity by moisture content. Further genetic studies will be needed to confirm the correlation between high energy x-rays and the cause of plants component change.

This study was conducted to investigate the effect of treatment with squeous chlorine dioxide and hot water on the germination of radish (Raphanus sativus L.) seeds, and reduction of microbial load on the seeds. Increases in treatment and the concentration of aqueous chlorine dioxide in water resulted in increasing reductions in the counts of total aerobic microbes. Seeds treated with aqueous chlorine dioxide (100 ppm/20min, 200ppm/20min) showed about a 10-fold decrease in microbial loads. Germination of seeds was not adversely affected by any treatment tested, although the germination rate of seeds in the group treated at $55^{\circ}C$ for 20 min was reduced by 10% compared to that of control. Combined treatment with hot water and aqueous chlorine dioxide yielded better out comes in both microbial reduction and seed germination rate than did single treatments. A combined treatment with 100 ppm aqueous chlorine dioxide and hot water($45^{\circ}C$ or $50^{\circ}C$) resulted in about a 100-fold decrease in microbial load whereas germination rate showed only a slight increase to $97.0{\sim}97.7%$. Total aerobic microbial counts in radish seeds were decreased by aqueous chlorine dioxide and hot water treatment in the order. aqueous $CIO_2$+ hot water > aqueous $CIO_2$ > chlorinated water > hot water > control.

The effect of citric acid-aqueous chlorine dioxide ($ClO_2$) treatment of radish seeds artificially contaminated with Salmonella typhimurium was studied. Radish seeds were inoculated by immersion, in more than 106 log CFU/g seed, of a suspension of S. typhimurium, dried, and stored sealed at $4^{\circ}C$ Radish seeds soaked in 200 ppm aqueous ClO2 solution for 10 min showed a bacterial reduction of 1.08 log CFU/g seed, and the lowering of microbial burden noted in seeds soaked in 2% (w/v) citric acid solution for 10 min was 2.89 log CFU/g seed. Next, radish seeds were exposed to 0.5% (v/v) glycerol solution for 10 min either before or after treatment with 200 ppm aqueous ClO2 or 2% (w/v) citric acid for 10 min. Glycerol exposure after citric acid treatment reduced bacteria by 3.46 log CFU/g seed, and glycerol treatment after aqueous $ClO_2$ treatment reduced the microbial burden by 2.14 log CFU/g seed. Both glycerol treatments yielded better elimination of S. typhimurium than did a single treatment with either citric acid or aqueous $ClO_2$. Radish seeds inoculated with S. typhimurium were treated throughout the entire growth period. Although radish seed treatment was effective, treatment by citric acid and aqueous $ClO_2$ after sprouting was not effective to eliminate S. typhimurium.

In this study, we investigated the potential of 70% ethanol extracts from wild edible plants (Pueraria lobata sprout, Rosa multiflora sprout, Artemisia princeps leaf, Diospyros kaki leaf, Morus alba leaf, Robinia pseudoacacia flower, Inula britannica var. japonica flower), as natural antioxidants. The antioxidant contents and activities of extracts were examined using various methods. The measurements of total polyphenol content revealed that Rosa multiflora sprout extract had the highest value and total flavonoid content showed that Diospyros kaki leaf extract had the highest value. Antioxidant activities were the highest in Rosa multiflora sprout for DPPH (IC₅₀ 232.52 ㎍/mL), ABTS⁺ (IC₅₀ 470.10 ㎍/mL), superoxide^- (IC₅₀ 431.88 ㎍/mL), nitrite (IC₅₀ 363.38 ㎍/mL) scavenging activity, and reducing power (2.47 O.D.). These results suggest that the ethanolic extract of Rosa multiflora sprout is a potential source of natural antioxidants.

Since Traditional Korean medicine (TKM) doctors use various knowledge systems during treatment, diagnosis results may differ for each TKM doctor. However, it is difficult to explain all the reasons for the diagnosis because TKM doctors use both explicit and implicit knowledge. In this study, an upgraded random forest (RF)-based evaluation tool was proposed to extract clinical knowledge of TKM doctors. Also, it was confirmed to what extent the professor's clinical knowledge was delivered to the trainees by using the evaluation tool. The data used to construct the evaluation tool were targeted at 106 people who visited the Sasang Constitutional Department at Kyung Hee University Korean Medicine Hospital at Gangdong. For explicit knowledge extraction, four TKM doctors were asked to express the importance of symptoms as scores. In addition, for implicit knowledge extraction, importance score was confirmed in the RF model that learned the patient's symptoms and the TKM doctor's constitutional determination results. In order to confirm the delivery of clinical knowledge, the similarity of symptoms that professors and trainees consider important when discriminating constitution was calculated using the Jaccard coefficient. As a result of the study, our proposed tool was able to successfully evaluate the clinical knowledge of TKM doctors. Also, it was confirmed that the professor's clinical knowledge was delivered to the trainee. Our tool can be used in various fields such as providing feedback on treatment, education of training TKM doctors, and development of AI in TKM.
