Chinese cabbage is a vegetable of Cruciferous family. It was usually consumed as Kimchi. It was known to have amount of vitamin c. Recently the trend for the development of functional food combined with oriental herbs. For this aim the study was performed to evaluate the hepatoprotective effect via antioxidant activity of leaf and root of Sanchon Chinese cabbage(Brassica campetris L.) comparatively. The methanol extracts of Chinese cabbage were tested for investigating the effects on the formation of lipid peroxide and the activities of free radical generating enzyme in vitro in bromobenzene-treated rats. The methanol extracts of chinese cabbage reduced bromobenzene-induced hepatic lipid peroxidation and inhibited the activity of xanthine oxidase. The methanol extracts of chinese cabbage did not activate amionopyrine N-demethylase, aniline hydroxylase and glutathione S-transferase. Epoxide hydrolase activity was decreased by bromobenzene, which was restored by pretreatment of the methanol extracts of chinese cabbage. The results suggest that the methanol extracts of Chinese cabbage is reduced by enhancing the activity of epoxide hydrolase.

In 1997 surveys 82 out of 180 crucifer fields were infected with clubroot disease in a range of 1-100% of diseased plants and among crucifier crops Chinese cabbage was the most severe, In cropping systems Chinese cabbage-monocropping of Chinese cabbage-radish were found to be most common in major Chinese cabbage production areas. Welsh onion squash or paddy rice were also planted between cropping of Chinese cabbage. Paddy fields converted to upland were lowered in incidence of clubroot disease and fields with loam to silty loam soil were more severe in disease than those with sandy soil. Soil pH and organic contents were nor related to clubroot disease severity. Soil fauua such as total fungi bacteria actinomyces Pseudomonads and Bascillus were not correlated with severity of the disease. Root rall development on Chinese cabbage seedlings was initifially observed under a microscope 13 days after inoculation with Plasmodiophora brassicae but 18 days by naked eyes after inoculation. Root galls were formed mostly around collar roots and gradually spread to main root lateral roots and secondary root branches. Root galls started to enlarge greatly in size and weight from 23 days after inoculation. Chinese cabbage plants at mid-growth stage with root gall development were reduced to 1/2 of that of healthy plants in number of leaves 1/4-1/5 in above ground fresh weight 1/6 in root length but increased to 3 times in diameter of collar root. Diseased plants had little root hairs. Diseased Chinese cabbage plants at harvest were reduced by 9,1-11.8% in head weight compared to healthy plants a positive correlation was observed between root and head weight but those relationships were rot found in the diseased plants.

In recent years consumers have become used to products geared toward a more convenient lifestyle, thus, the demand for salted-cabbage, for use in preparing Kimchi is increasing. This study aims to investigate purchasing factors, the satisfaction and demands of salted-cabbage, and to ascertain a marketing strategy for expanding the use of salted cabbage in food-service departments of schools. Self-administered questionnaires were collected from 131 buying agents who manage food materials for schools, and statistical data analysis was completed using the SPSS V.14.0 program. 46.9% of the participating respondents were from elementary schools, 27.7% from middle schools, and 25.4% were from high schools.. Most of the subjects (67.9%) recognized the salted cabbage retailed for foodservice, but 62.3% of these had not purchased them, due to both their lack of trust in the sanitation and raw material handling of the food product, and the high price. Respondents considered different factors when deciding whether or not to purchase: the origin (local or imported) of the cabbage, hygiene, and taste, as well as characteristics such as the cabbage weight, package weight, and package materials. The score of post-behavior intentions as well as overall satisfaction was rather high. Also, they perceived the need of strategic promotion for enlarging the market portion of salted-cabbage. These results will done the guidelines for diversifying the salted-cabbage market and for creating an added value of agricultural products in rural areas.

Objective: This study was conducted to evaluate nutritional value and in situ degradability of fruit-vegetable byproducts and their feeding effects on performance of growing Hanwoo steers. Methods: Nutritional value and in situ degradability of cabbage, Chinese cabbage and fruit-vegetable byproducts were assessed. In vivo feeding trial was also performed for 12 weeks. Thirty-six growing steers were randomly allocated into three groups according to body weight (BW) and age in 12 pens (4 replications/treatment) and assigned to one of the three dietary treatments: control (byproduct 0%), FV-B (fruit-vegetable byproduct 20%), and CA-B (cabbage peel 15% plus Chinese cabbage peel 15%, total byproduct 30%). Results: The crude protein contents of cabbage, Chinese cabbage and fruit-vegetable byproducts were 18.69%, 20.20%, and 10.07%, respectively. Concentrations of neutral detergent fiber (NDF) were higher in cabbage (22.31%) and Chinese cabbage (28.83%) than fruit-vegetable (13.94%). Higher concentrations of non-fiber carbohydrate were observed for fruit-vegetable (66.72%) than cabbage (44.93%) and Chinese cabbage byproducts (24.69%). The effective degradability (ED) of both dry matter (DM) and NDF for fruit-vegetable byproduct (DM, 84.69%; NDF, 85.62%) was higher (p<0.05) than cabbage (DM, 68.47%; NDF, 55.97%) and Chinese cabbage byproducts (DM, 68.09%; NDF, 54.22%). The DM intake was not different among treatments because the amount of feed was kept constant according to the BW of growing steers to prevent overweight during the growing period. The average daily gain during the whole experimental period was not different among treatments (1.26, 1.25, and 1.34 kg/d for control, FV-B, and CA-B). The ED of both DM and NDF degradability of the total mixed ration (TMR) diets were very similar among treatments. Feed conversion ratio during the whole period showed no significant difference among treatments. Conclusion: This study demonstrates that fruit-vegetable and cabbage byproducts up to 20% and 30% (as fed basis), respectively can be included in TMR diets for growing beef cattle.

Since Chinese cabbages weigh 3 to 5kgf and are big in size at the time of harvest, handling operations such as harvesting, loading and unloading including transportation require the highest labor demand among all other cultivation processes. Recently, though several cabbage harvesters were developed in Japan and Europe, those harvesters were not suitable for Chinese cabbages cultivated in Korea because of the size and shape. The cabbage harvester is almost meaningless without any proper cabbage piling and pallet unloading mechanism. Most harvesters developed so far adopted a sort of slide and free falling way in collecting cabbages into the pallet. Three or four labors are usually required for cleaning incoming cabbages and loading those in the pallet. Because of the required time for piling cabbages without severe damage and the required space capacity to carry empty and loaded pallets, harvesting speed should be adjusted in accordance with time required for consecutive operations. Up to now, any automatic or semi-automatic collecting device has not been developed in the world to pile cabbages on the layer one by one into the pallet in the ordered way with little damage and to unload pallet from the harvester continuously during the harvest process. To compromise system expenses and function, Semi-automatic cabbage piling and pallet unloading mechanism was devised and it required one labor. The foldable mesh pallet with a size of 1050mm x 1050mm x 1000mm and holding capacity of around 70 cabbages was utilized. The prototype for piling and unloading mechanism was composed of three parts such as feeding device, automatic piling device with retractable bellows, and pallet unloading device. Prior to developing the prototype, the geometric properties and the amount of the damage of the cabbage caused during the piling operation were investigated. Considering the height of the pallet, a series of cabbage carrying plates were mounted to the bracket chain to lift and to carry cabbages to the loading device. Indoor laboratory experiments showed that the cabbage carrying chain conveyor worked successfully. Considering the conveying speed 0.46m/sec of the pull up belt from the cabbages on the ground, the speed of cabbage carrying chain conveyor worked property in the range of 0.26m/sec to 0.36m/sec. The system allowed the operator to modify the position of cabbage slightly. Overall system worked successfully resulting into almost same capacity without severe damage to the cabbage as human did.

This study was designed to investigate quality characteristics of Korean cabbage kimchi added with germinated brown rice extracts (GBRC; (A) and CBREP; (B)) and Korean cabbage kimchi on the market mom the result pH and total acidity were shown to be similar in all samples. In the case of Korean cabbage kimchi added with (A) and (B), content of total sugar and reducing sugar were higher than those of Korean cabbage kimchi on the market. Color values (L, b) were shown to be similar in all samples in which a value was lower than that of Korean cabbage kimchi on the market. The amounts of total amino acid and free amino acid of Korean cabbage kimchi added (A) and (B) were higher than those of Korean cabbage kimchi on the market. But the amount of $\gammma$-aminobutyric acid (GABA) in main functional components of germinated brown rice was shown to be low. Total phenol content and other antioxidant and anticoagulant activities of Korean cabbage kimchi fortified with (A) and (B) were higher than those of Korean cabbage kimchi on the market. In conclusion, Korean cabbage kimchi added with (A) and (B) were shown to be similar in fermentation tendency compared to Korean cabbage kimchi on the market and, the functional properties could be enhanced by the addition of (A) and (B).

Although the storage period of raw baechu cabbage could be 2 months at $0{\sim}2^{\circ}C$, 1 month was appropriate considering the quality of the baechu cabbage, waste ratio, and storage cost. The polyethylene container was the most efficient storage container among polypropylene box, polypropylene net and polyethylene container. pH of a brined baechu cabbage using raw baechu cabbage was 4.0~4.3 after 8 weeks and its total bacteria and lactic acid bacteria counts were $10^7$ cfu/g, and textural property (springiness) lower than 50% was at 8th week of storage at $0{\sim}2^{\circ}C$ and thus its storage period was limited to 8 weeks. When brined baechu cabbage was prepared by raw baechu cabbage stored for 1 month at $0{\sim}2^{\circ}C$, its pH, microorganism counts and springiness showed similar trends to the brined cabbage using raw baechu stored for 0 month. However, its rates of change were faster than the brined baechu cabbage using the raw baechu, and the storage period was limited to 6 weeks. Brined baechu cabbage using the raw cabbage stored for 2 months and its storage period was limited by about 4 weeks judging by its indicated quality characteristics.

Protoplasts isolated from inbred lines of Brassica oleracea L. var capitata (cabbage) and Brassica campestris L. ssp. pekinensis (Chinese cabbage) were fused by PEG-mediated method, and somatic hybrid cells were differentiated into plants. for the identification of somatic hybrid plants, ploidy level, plant morphology, and cytological analysis were performed. All of the regenerated plants derived from fused protoplasts were shown to be 2X-4X, or higher ploidy level, presumably due to somatic hybridization or chromosome doubling. The morphology of leaves, petioles, and flowers showed an intermediate phenotype between Chinese cabbage and cabbage. Chromosome numbers in these somatic hybrids ranged mostly from 33 to 38. According to Genomic in situ hybridization (GISH) pattern, signals from both fusion parents of B.campestris or B.oleracea were detected in different colors when chromosomes of putative somatic hybrids were observed.

The changes of chlorophylls and pH of cooked water were investigated in blanched and fermented cabbage. In blanched cabbage, pheophytins were increased markedly with heating time. This was related to the changes of pH and the effects of heat. One minute blanching accelerated the formation of chlorophyllides by the activation of chlorophyllase. In fermented cabbage, pH and chlorophylls were decreased rapidly at the beginning of fermentation. At the final of fermentation, all chlorophylls and chlorophyllides were converted to pheophytins ana pheophorbides, and the content of pheophytins was higher than the content of pheophorbides. The content of pheophorbides in fermented cabbage was higher than that in blanched cabbage.

This study was carried out to investigate seed germination and seedling of cabbage and sugar beet in four treatments of salinity including 0 (control), 0.5, 1.0 and 1.5％ NaCl. The results showed that different treatments of salinity had considerable effects on the germination and root and shoot length of cabbage and sugar beet. Percent of germination in both species showed significant decrease with increasing salinity up to 1.5％ NaCl. This decrease was more evident in cabbage when compared to sugar beet. The required time for germination increased with high levels of salinity. The seedling growth of both species were inhibited by all salinity levels. Particularly at 1.0 and 1.5％ NaCl, no measurable length was observed in cabbage and sugar beet. At 0.5％ NaCl root growth of both plant species was more affected as compared to shoot growth by salinity.
