Remote sensing can be used to provide information about the monitoring of crop growth condition. Recently Unmanned Aerial Vehicle (UAV) technology offers new opportunities for assessing crop growth condition using UAV imagery. The objective of this study was to assess weather UAV aerial images are suitable for the monitoring of highland Kimchi cabbage. This study was conducted using a fixed-wing UAV (Model : Ebee) with Cannon S110, IXUS/ELPH camera during farming season from 2015 to 2016 in the main production area of highland Kimchi cabbage, Anbandegi, Maebongsan, and Gwinemi. The Normalized Difference Vegetation Index (NDVI) by using UAV images was stable and suitable for monitoring of Kimchi cabbage situation. There were strong relationships between UAV NDVI and the growth parameters (the plant height and leaf width) ($R^2{\geq}0.94$). The tendency of UAV NDVI according to Kimchi cabbage growth was similar in the same area for two years (2015~2016). It means that if UAV image may be collected several years, UAV images could be used for estimation of the stage of growth and situation of Kimchi cabbage cultivation.

This study was conducted to investigate the standardization of kimchi and related products. There are about 339 kinds of kimchi and related products in Korea. Half of those various kimchi was 50% of the total products, and the other groups are in the order of Jangachi (high salted vegetable pickles, Saengchae (a salad type kimchi), Kakduki(reddish kimchi), Keotjulyi(nonfemented kimchi), Pickles, Seobakji (kimchi based on raddish, fish and other ingredients) and Shickgae (lactic fermented fish products). About 200 ingredients (chinese cabbage, raddish, cucumber, other vegetables, fruits, seaweeds, fish, meat etc.) were used for those products. Tongbaechu kimchi (whole headded chinese cabbage kimchi) and Possam kimchi (wraped kimchi with chinese cabbage leaves) were made by about 30 ingredients, respectively. Kakduki, Oyster-kakduki, Chonkak kimchi (kimchi based on small raddish with leaves) and Tongchimi (raddish kimchi with brine soup) were made by raddish and more than 10 ingredients, but the subsidiary ingerdients were less than that of chinese cabbage kimchi. Other products such as Yulmu kimchi and Oisobaki (a cucmber kimchi) were also dicussed.

This study aims to find out the devices to minimize the amount of nitrate ingested from kimchi, the main way of vegetable intake for Koreans, and the basic data to deliver to calculate the total daily intake for Korean, investigating the year-round changes of nitrate content in vegetables for Kimche raw material, and changes of nitrate content by salting of chinese cabbage, and stewed kimchi through the use of different cooking methods. The results obtained were summarized as follow: over between 205-6655mg/kg f.w. in chinese cabbage, 480-3970mg/kg f.w. in chinese radish, 157-5820mg/kg f.w. in lettuce and 29-520mg/kg f.w. in cucumber respectively. Therefore it was strongly adviced to introduce the nitrate limit value of vegetables in Korea if the nitrate content in Kimchi should be reduced to meet the nitrate ADI(Acceptable Daily Intake, 219mg60kg b.w) of FAO.WHO, because the nitrate content in Kimchi reflects the nitrate content in vegetables. In order to keep the low nitrate content in Kimchi. it was adviced to remove the outer leaf which contains 2-3 times higher nitrate content compare to the inner leaf at the time of preparation, i.e. chinese cabbage, before the soaking treatment in salt solution for Kimchi making process. The dehydration by soaking treatment in salt solution occurred at 0.9%~4.7% in leaf midrib and more than 13%~24% in leaf blade. The nitrate content after soaking in salt solution was increased 107%~123% compared with before soaking, increasing rates of nitrate content in the outer and inner leaf midrib were higher than those in leaf blade. The increase of nitrate content in salt solution after soaking due to the dehydration of chinese cabbage by soaking treatment. The Kimchi stew(Kimchi JJige) was processed with and without animal oil, but the amount of nitrate in kimchi stew did not decrease both treatments, but it increased after the processing since the water in Kimchi stew has got low by boiling.

절임 배추와 숙성된 김치의 동결저장 가능성을 조사하였다. 생배추의 조직은 급속침지동결이나 예비건조하면 완만공기동결이나 건조하지 않은 것에 비해 우수하였다. 절임 배추는 생배추에 비해 동결손상이 적었고 급속동결이나 예비건조에 의해 조직이 개선되지 않아 조직특성은 숙성된 김치와 비슷하였다. 김치는 동결시 동결하지 않은 것에 비해 약간 질겼으나 전체적인 품질에서는 유의적인 차이를 보이지 않았다. 동결저장시 절임배추는 3개월후 약간의 핑크색을 띄었으나 김치는 6개월 저장동안 이런 현상이 나타나지 않았고 품질도 거의 변화가 없었다.

In vitro anticancer effect of Chinese cabbage kimchi fractions was investigated by using human cancer cells, AGS human gastric adenocarcinoma cells and HT 29 human colon adenocarcinoma cells. The Chinese cabbage kimchi(fermented for 4 days at 15oC) was fractionated into 7 groups, methanol extract, hexane fraction(fr.), methanol soluble fr., dichloromethane fr., ethylacetate fr., butanol fr. and aqueous fr.. Chinese cabbage kimchi fractions inhibited the growth of AGS and HT 29 cancer cells as dose dependent. In particular, the dichloromethane fr. showed the highest inhibitory effect among other fractions. When the dichloromethane fr.(0.2mg/ml) was treated, the number of AGS and HT 29 survival cancer cells reduced to 12$\times$104/ml and 11$\times$104/ml compared to 166$\times$104/ml and 50$\times$104/ml of the controls, respectively. Chinese cabbage kimchi fractions also inhibited the DNA synthesis of the cancer cells. They inhibited the DNA synthesis of AGS human gastric adenocarcinoma cells more efficiently than that of HT 29 human colon adenocarcinoma cells. These results indicate that Chinese cabbage kimchi fractions show in vitro anticancer activity and the dichloromethane fr. among them reveals the highest effect.

Hydroponic cultivation is a technology of raising crops without use of soil. Generally farmers use the method of DFT(deep flow technology)to grow leafy or fruity vegetables; however, systematic and scientific researches are insufficient on this matter. This study investigated the possibility of cultivating Chinese cabbage steadily year long by using the method of DFT. Chinese cabbage was cultivated hydroponically with and without Ge addition, used to prepare kimchi, and the chemical and microbiological characteristics of kimchi were compared. The basic hydroponic cultivation condition was as follows: 30 days after seeding, the raised seeds were moved to a hydroponic bed and given underground water for 3 days so the roots grow normally Standard nutrient solution was provided and the early electric conductivity concentration was maintained between 1.5∼2.5 thickness. The temperature of the solution was maintained between 10 ∼25$^{\circ}C$ to allow the growth of Chinese cabbage. When soil-cultivated, organically cultivated and hydroponically cultivated Chinese cabbages were compared, hydroponically cultivated cabbages were smaller in size and showed less ability to build up and fold leaves into a head, but showed better quality than organically cultivated cabbages. The contents of protein and fat showed no significant differences. The contents of water. Ca, P, Fe, Vitamin A and Niacin were higher in control and Ge-added cabbages compared with soil-grown cabbage. There was no difference between soil-cultivated Chinese cabbage kimchi and hydroponically cultivated Chinese cabbage kimchi.

The effects of salting degree of cabbage on the chemical, microbiological, textural changes and taste of Korean whole cabbage Kimchi fermented at $21^{\circ}C$ was studied. Low salted Kimchi (1.8% NaCl, soaking for 2 hr. in 20% brine) was showed higher total acdity than high salted Kimchi II(3.1% NaCl, Soaking For 8 hr in 20% brine) and III(2.9% NaCl, no soaking in 20% brine). The changes in growth of lactic acid bacteria was relevant to the salt content of whole cabbage Kimchi. Kimchi I was showed higher growth rate of Lactic acid bacteria and slower death rate constant of Lactic acid bacteria than that of Kimchi II and III. In palatability test, salty taste of Kimchi II, III was more salty than that of Kimchi I ($p{\leqq}0.01$) and total evaluation of Kimchi I, II was more palatable than Kimchi III ($p{\leqq}0.05$) at 3rd's day (optimum taste). Cutting force by Rheometer was well correlated with the salt content of Kimchi.

This study compared and analyzed the consumption and amount of red pepper used in Baechu Kimchi (cabbage Kimchi) especially the amounts used in Kimchi recipes with respect to the passage of time from the 1930s to the 2010s. In this analysis, 78 recipes for cabbage Kimchi were taken from books, daily newspapers and magazines from 1930 to 2014 and collected for comparison. The result of the study showed that the consumption and inclusion of dried red pepper powder in cabbage Kimchi increased. The average consumption of red pepper in the 1930s was 5.75 g, and the number went up to 8.83 g in the 1940s, to 13.8 g in the 1950s, and to 20.25 g in the 1960s. The amount dramatically increased from 1970 to 1980 (53.37 g) and kept rising until 2010 (71.26 g). The average consumption of red pepper in cabbage Kimchi in the 2010s is about 12 times that of the 1930s.
