This study determined the removal ofrates for three types of pesticides which were spiked from Chonggak radish during the preparation of chonggak kimchi. When Chonggak radish (leaves) were brined with 10% salt solution and rinsed with water, the removal rate of the three pesticides was 43.8%, 41.9% and 89.8% for diazinon, diniconazole and dimethomorph, respectively. When Chonggak kimchi (leaves) were prepared and fermented for 4 weeks at 4℃, the removal rate of the three pesticides was 82.4%, 77.2% and 98.9% for diazinon, diniconazole and dimethomorph, respectively. Pesticide residues in chonggak radish (roots) were removed by up to 54.7-85.1% of initial concentration through brining and washing. During the fermentation of chonggak kimchi (roots) for 4 weeks at 4℃, the amount of pesticide residues was decreased by 94.0%, 91.8% and 90.0% of initial concentration for diazinon, diniconazole and dimethomorph, respectively. The highest relative removal rate by percentage for the three pesticides asreached 66.5% by salting chonggak radish (leaves). On the other hand, the highest relative removal rate by percentage of pesticides was shown during fermentation, reaching 51.8% and 55.8% for diazinon and diniconazole, respectively, in Chonggak kimchi (roots). As a result of examining the differences ofbetween the three pesticide removal rates rates according to temperature while fermentedduring fermentation of Chonggak kimchi with three pesticides for 4 weeks at 0℃ and 4℃, diazinon pesticide removal was has a high pesticide removal rate of 2.7-10.8% from fermented Chonggak kimchi (roots) at 4℃ compared to 0℃. In the other pesticides, the difference in removal rate of the pesticideresidual pesticides residues by aging temperature was found to be insignificant.

Research on the birth (起源) and names (語源) of foods such as kimchi is important to understand traditional food culture. kimchi, an 'add flavored, fermented, pickled, vegetable food' was initially prepared with the simple purpose of increasing storage capabilities, but later, through a complex process of change, morphological diversification occurred. In addition to the basic name of 'kimchi', each variety has its unique name and history. This study was conducted through qualitative research using various research methods, such as oral records and interviews, as well as investigation of data from literature, including ancient literature, modern cookbooks, newspapers, magazines, papers, and videos. The study sought to investigate the context and the meaning of the name Chonggak kimchi. In addition, it is a compilation of how the name spread through the ages and evolved to its current name. The name Chonggak kimchi did not exist during the Joseon Dynasty and Japanese occupation and first appeared in the records in the late 1950s. Nevertheless, the original name of 'Altarimu kimchi' evolved and finally became a part of the standard Korean language (標準語) in 1988. In the process of the name spreading and becoming popular, the movie "Chonggak kimchi (1964)," starring Shin, S.I., and Eom, A.R. played a significant role. It was also confirmed that this was a meaningful and valuable case of contentization of traditional food culture, regardless of the intention behind the same.

In order to establish the basic scientific data on the fermentation characteristics of chonggak kimchi (CGK), we studied with CGKs prepared at different seasons and stored at various temperatures ($5{\sim}23^{\circ}C$). Changes in pH and acidity of CGK fermented at different temperatures were typical. However, acidity of summer CGK stored under $15^{\circ}C$ did not reach 1.0% since the amount of reducing sugar in the summer radish was lower by over 1% than the ones from the other seasons. Growths for Leuconostoc and Lactobacillus spp. over 8.0 logCFU/mL were observed in CGKs fermented above $10^{\circ}C$. Changes in Max G, cutting force, of CGK from different seasons were apparent. Max Gs for spring and summer CGK were decreased immediately right after storage while Max Gs for winter CGKs were increased slowly during storage. According to the results of sensory evaluation, CGKs revealed the highest overall acceptability when acidity of kimchi reached $0.7{\pm}0.1%$ under the given fermentation condition. However, CGK prepared with radish from winter or summer season tasted better than the one made in the spring. But the edible periods for winter CGKs were longer, compared with summer CGKs fermented at the same temperature. In conclusion, CGK fermented at $10^{\circ}C$ in the winter season gives a better taste with longer edible duration than the other CGKs.

The limit sowing time and the growth of radish cultivated in late fall were studied in relation to the effects of varieties and polyethylene film mulching. The root weight of Dehyung-Chusuk radish sowing in September 8th in Suwon was 520g but 718g in mulched plot. In Pusan the root weight of radish sowing on September 16th and harvested on November 23rd was 655g in Bekkyung and 813g in Dehyung-Chusuk variety, but more than 1000g in mulched plots of two varieties all. The effect of mulching was higher in Dehyung-Chusuk than in Bekkyung. The experimental results of Altari varieties will be recommandable in limit sowing time as around September 14th in mid-northern area and around September 18th in mid-southern area. Chonggak Altari was better than Chammat Altari in root formatiion. Two varieties all revealed good growth in the plots of sowing on September 26th in Pusan.

A survey of the notion and intake on Kimchi among college women in Pusan was conducted to get some basic information on kimchi. Two hundred sixty seven students in Pusan participated in this survey. Seventy five percent of students answered that they like kimchi. They preferred well-fermented kimchi with anchovy extracts, refreshing taste and crispy texture the saltly and sweet. Chinese cabbage kimchi (87.6%) was found to be the most favored kimchi and Kakdugi(seasoned pickles of cubed radish), Nabak kimchi and Chonggak kimchi (ponytail kimchi) were followed in the order. The most favorite food made from kimchi was stir fried kimchi with rice. They disliked traditional special kimchi, such as Puchu kimchi (leek kimchi), Pa kimchi (green onion kimchi), Kkennip kimchi (perilla leaf kimchi), Godulbaegi kimch (Korea wild lettuce kimchi) and Gat kimchi (Leaf mustard kimchi). About 93 grams of kimchi was consumed daily and this amount was a little. Seventy percent of students did not have any experiences preparing kimchi. Experiences of kimchi preparation were given by mother through kimchii-making event for the winter(71.7%), cooking practice in middle or high school (14.1%) and college(10.9%) and general cooking education (33%). They preferred to buy kimchi at the Agricultural Cooperative Association (48.5%) or a large kimch factory (32.75). College students believe that kimchi is a healthy food and are willing to learn how to make kimchi.

This study examined elementary school students' perceptions and acceptances related to kimchi in Jecheon area. This study examined with 388 elementary school students. Demographic characteristics of subjects, perceptions and acceptances related to kimchi were surveyed by self-developed questionnaires. Exactly 54.1% of subjects ate kimchi more than once per day, whereas 2.8% of subjects never ate kimchi. With regard to location, the home showed the highest percentage. Exactly 94.3% of respondents answered that eating kimchi was good for health. For acceptance, 86.9% of respondents answered that they liked kimchi. Reasons for liking kimchi were texture and special taste in order, whereas the most common reason for disliking was spicy taste. Baechu-kimchi (Chinese cabbage kimchi) was highly preferred, whereas pa-kimchi (green onion kimchi) was not. Subjects with an extended family preferred oisobagi (cucumber kimchi). There were significant differences between the groups with balanced dietary habits and unbalanced dietary habits in terms of acceptance for chonggak-kimchi (small radish kimchi), yeolmu-kimchi, kkadugi, mulkimchi (watery kimchi) and oisobagi. Elementary school students in Jecheon area recognized the importance and necessity of kimchi in Korean meals. Exactly 23.7% answered spicy taste as the reason for liking reason while 37.3% answered spicy taste as the reason for disliking. These results suggest that various kinds of kimchi need to be developed for elementary students with different levels of spiciness in addition to continuous nutrition education about balanced dietary behaviors at school and home.

The study is being conducted to investigate the perceptions and preferences of the Korean kimchi by the Chinese international students in Jeonbuk area. Self-administered questionnaires were collected from 197 male (48.9%) and 203 female (51.1%) students. Statistical data analysis is being completed using SPSS v. 12.0. Approximately 95% of Chinese female and 91% of male students know about kimchi before coming to Korea through the Korean movies and dramas. The perceptions for kimchi according to the residence period showed a significantly difference 'kimchi is a nutritious and health food' (p<0.05), 'kimchi has good taste but too hot to eat' (p<0.05), and 'Kimchi is difficult to eat because of the smell' (p<0.05). Approximately 52% of Chinese female and 44% of male students consumed kimchi once or twice a day. The most popular form of kimchi among the 13 varieties was baech kimchi. Chinese female students preferred the 'kkakdugi' (p<0.05), 'chonggak kimchi' (p<0.05), and 'young radish kimchi' (p<0.05) more than the male students. The most liked reason was the 'refreshing taste' (44.8%) whereas the most disliked reasons were 'unfamiliar with eating kimchi' (28.7%) and 'sour taste' (24.2%). Approximately 85% of Chinese female and 60% of male students would like to experience making kimchis by themselves. Extended kimchi consumptions for Chinese answered 'not too fish-like smell' (36.0%), 'not too overly-ripe' (34.5%), 'not too sour' (25.4%), and 'not too hot' (25.4%). Therefore, in order to improve the awareness for kimchi among Chinese students, we need to relate kimchi with the taste of Chinese traditional foods.
