In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80's of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin $B_6$ were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.

A group of 132 pre-school children with a mean age of six years and one month was the subjects of this investigation. These children were members of three nursery schools locating in Kwang-ju city. Each child's mother replied to a questionaire which included 42 food items and 4 questions. The results showed that the food preference of each child was variable and the group as a whole expressed more positive than negative feelings. The average number of foods liked per child was 22.9(range: $7{\sim}42$) among 42 food items. Peach, Apple, Strawberry, Laver, Egg, Tomato, Sweet Potato, Tangerine Orange and Beef were ranked in descending order of 'like' ratings. The average number of foods refused was 4.9 (range: $0{\sim}25$). Onion, Liver, Red Pepper Leaf, Root of Bellflower, Taro, Wild Seasame Leaf, Egg Plant, Cabbage, Water Cress and Bracken were ranked in descending order of 'refuse' ratings. The odor of hurting feelings, the hot taste and the flabby texture were the reasons why the children refused these foods. The average number of foods unexperienced was 4.4 (range: $0{\sim}14$). Kidney, Dried Small Whitebail, Tangle (DA SHI MA), Liver, SA RI Mushroom, Acorn Mook, Dried Fragrant Mushroom, Pine Agaric, Root of Bellflower and Ped Pepper Leaf were ranked in descending order of 'unexperience' ratings. Children's 'like' rating toward total foods was 57.3% and the 'refuse' rating was 11.7%. Among eight food groups, fruits showed the highest favority (91.4%) and mushroom showed the least (25.9%). The difference between male and female in the preference of total foods did not showed significant level. But the difference were significant in those of individual food groups; other vegetables, green and yellow leafy vegetables, mushrooms(above, p.<01), fishes and shellfish and sea weeds (above, p<.05). Children who had experienced meals missed rated 59.1% and 34.1% of these children missed meals once a week. The main reason for maels missed was due to the heavey snacks before meal time. Children who had snacks twice a day rated 45.6%. Main foods used as their snacks were starch foods (Cake, Biscuit, Sweet Potato) and citrous foods (Fruits, Apple, Tangerine).

We tested the effects of dietary intake of freeze-dried Korean traditional fermented cabbage (generally known as kimchi) with varying amounts of sodium on blood pressure and cardiac hypertrophy in spontaneously hypertensive rats (SHRs). Wistar-Kyoto rats (WKY), as a control group, received a regular AIN-76 diet, and the SHRs were divided into four groups. The SHR group was fed a regular diet without kimchi supplementation, the SHR-L group was fed the regular diet supplemented with low sodium kimchi containing 1.4% salt by wet weight, which was provided in a freeze-dried form, the SHR-M group was supplemented with medium levels of sodium kimchi containing 2.4% salt, and the SHR-H group was supplemented with high sodium kimchi containing 3.0% salt. Blood pressure was measured over 6 weeks, and cardiac hypertrophy was examined by measuring heart and left ventricle weights and cardiac histology. SHRs showed higher blood pressure compared to that in WKY rats, which was further elevated by consuming high sodium containing kimchi but was not influenced by supplementing with low sodium kimchi. None of the SHR groups showed significant differences in cardiac and left ventricular mass or cardiomyocyte size. Levels of serum biochemical parameters, including blood urea nitrogen, creatinine, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, sodium, and potassium were not different among the groups. Elevations in serum levels of aldosterone in SHR rats decreased in the low sodium kimchi group. These results suggest that consuming low sodium kimchi may not adversely affect blood pressure and cardiac function even under a hypertensive condition.

While environmental pollution being developed, there have been some cases that residents on certain parts of Seoul area have cultivated vegetables in a small scale, and consumed the produce of theirs thinking them not polluted. Therefore the need for study about whether those vegetables and soil were polluted was growing. In this study, Seoul area (Tobong-dong, Chang-dong, Wolgyedong, P'il-dong, Oksu-dong, and Karibong-dong) and Kyanggi area (Changhang, P'och'an, Kap'yang, Yangp'y~ng) where pollution was thought to be less severe than that of the former were selected for the sampling area. Cabbage, pumpkin and young pumpkin were sampled and dried to be analyzed the contents of Cd, Cr, Cu, Ni, Pb, Zn, and moisture content was also analyzed. And at the same time 0.1 N-HCl soluble heavy metal content of soil was measured, and the results obtained were descrived as follows. Heavy metal contents of soil in Seoul and Kyonggi were Cd 0.184 ppm, 0.118 ppm, Cr 2.355 ppm, 0.441 ppm, Cu 29.16 ppm, 3.331 ppm, Ni 1.650 ppm, 0.829 ppm, Pb 26.77 ppm, 4.696 ppm, Zn 57.47 ppm, 14.94 ppm respectively. Heavy metal contents of cabbage in Seoul and Kyonggi were Cd 0.407 ppm, 0.241 ppm, Cr 0.388 ppm, 0.402 ppm, Cu 6.853 ppm, 4.486 ppm, Ni 1.479 ppm, 0.878 ppm, Pb 0.812 ppm, 0.258ppm, Zn 112.2 ppm, 54.86ppm respectively. Heavy metal contents of pumpkin in Seoul and Ky6nggi were Cd 0.011 ppm, 0.011 ppm, Cr 0,262 ppm, 0.197 ppm, Cu 3.302 ppm, 2.539 ppm, Ni 0.717 ppm, 0.369 ppm, Pb 0.257 ppm, 0.083 ppm, Zn 28.75 ppm, 14.01 ppm respectively. Correlation between heavy metal contents of soil and those of vegetables was represented high as a whole. In all heavy metals cabbage had higher values of concentrations than those of pumpkin (p<0.001). Concentrations of young pumpkin were higher than those of big pumpkin. It was probably due to the fact that young pumpkin containing not only inner part of pumpkin but also seeds was used as a sample. When classified by region, relatively high concentrations were observed in the samples of Karibong-dong, and in the sample of Jungtang riverside Cd was higher, and in the sample of Namsan Pb was higher than any other district.

김치는 우리의 전통식품으로서 가정마다 독특한 김치맛을 이어왔으나 최근 산업화와 주거환경의 변화 등으로 사먹는 김치의 수요가 늘고 있고 점차 레시피의 다양성을 요구하는 시대가 되었다. 그 지역의 기호에 맞는 김치를 표준화시키기 위해서는 지역민의 기호를 파악하고 이에 맞는 제품을 개발하는 것이 요긴하다고 생각된다. 따라서 지역의 특성에 맞는 고급김치를 개발하기 위하여 부산 및 부산인근의 예로부터 김치맛으로 유명한 명가김치들을 발굴하고 이를 현대화할 필요성이 높다. 따라서 이의 발굴을 위해 부산대학교 김치연구소내에 명가김치 선정위원회를 구성하고 여러 채널을 통해 9종의 통배추김치의 레시피를 발굴하였고 이를 공장김치나 문헌상의 김치의 레시피와 비교해 보았다. 이들의 통배추김치의 레시피상의 특징은 고춧가루, 마늘, 젓갈의 사용량이 많았고 젓갈은 대부분 자가의 멸치젓을 사용하고 있어서 맛이 진하고 매운 남부지방 김치의 특성을 나타내 주었다. 생선류와 청각 같은 해산물의 사용이 많았던 것도 중요한 특징으로 여겨진다. 다량의 고추가루를 개기 위하여 멸치 우린물이나 새우 우린물, 배ㆍ무ㆍ양파 즙을 사용하였고 찹쌀풀을 넣어 맛을 부드럽게 하였다. 재료의 선정에 매우 신경을 써서 좋은 배추를 구매하고 있었으며 고추가루는 색깔을 중시하여 태양초를 선호하였고 풍부한 고명의 사용도 명가김치로서의 품위를 높이는데 소중한 역할을 하고 있음을 알았다. 절인배추 1000 g에 대한 부재료의 비에서 명가김치와 타김치와의 차이가 확실하여 김치에 첨가하는 부재료들의 다양성과 함량이 김치의 맛과 품위를 높이는데 결정적으로 기여함을 알 수 있었다. 염농도는 일반적으로 알려져 있는 남부지방 김치의 특징인 짭짤한 김치는 많지 않아서 2% 부근의 슴슴한 김치가 많았고 이는 소량의 김치담그기, 냉장고의 일반화 및 저염화의 경향 등으로 설명할 수 있겠고 특히 대부분의 조사대상들은 김치의 소금절임 과정을 대단히 중시하여 슴슴하게 소금절임하는 것이 배추의 아삭아삭한 조직감을 유지하는데 중요함을 알고 있어 김치의 염농도와 조직감에 관한 연구가 계속되어져야 할 것으로 보였다.

Koryo(918-1352) made a certain progress in her culture and agriculture except the latter part of the era when the development in social economy were retarded due to military dictatorship and Mongol invasion. Despite of these external conditions, cultivations and kinds of horticulture foods were expanded With the help Of many king's agriculture first policy and the advancement in cultivating method . Among the horticulture foods, fruits such as peach, plum, Japanese apricot, apricot, cherry, pear, persimmon, pomegranate, crab apple, Jujube, grape, Chinese quince, walnut, orange, yuzu, chestnut, ginkgo nut(silvernut), pine nut, nutmeg nut, and fiat were crowed, and vegetables such as Chinese cabbage, turnip, radish, garlic, welsh onion, gynmigit, scallion, taro, malva, cucumber, white gourd, bottle gourd, water melon, eggplant, Japanese ginger, ginger and litchi were cultivated, while semi, water shieled and bamboo sprouts were taken in natural. Fruits were taken in natural or through dry, and particularly grapes were used to make wine, Flowers of Japanese apricots, some fruit trees, and chrysanthemum were also made into wine. Certain fruits were used as medicine owing to its medicinal nature. Vegetables were used to make Kimchi or to boil soup, sometimes they were dried to be kept in storage to be used in rare season and also used as medicine Increase in kinds of horticulture foods does not have any direct relation with the reform of social economy, but the fact that so many kinds of horticulture foods were cultivated and used in Koryo era shows that they elevated people's life and dietary culture.

Purpose: The objective of this study was to evaluate the biogas productivity of agricultural by-products (ABPs) based on their proximate composition. Specifically, the effects of proximate composition were investigated, and a new mixing method was developed using various ABPs that are difficult to digest for biogas production. Methods: Experiments were conducted to compare the biogas productivity between a single ABP and a mixture of ABPs that had the same proximate composition as the single ABP. To match the proximate compositions of radish waste and corn distiller's dried grains with solubles (DDGS), mixed ABPs were made from various ABPs. Biogas potential tests (BMP tests) were performed at an organic loading rate (OLR) of 2.5 g VS/L and a feed to microorganism ratio (F/M) of 0.5 under the mesophilic condition. Results: The individual ABPs (radish and corn DDGS) and the mixed ABPs (cabbage waste with skim milk waste, bean-curd waste with skim milk waste, and some others) produced similar amounts of biogas. Conclusions: The new mixing method based on proximate composition can be applied to other ABPs and organic wastes from factories and municipal waste treatment plants to develop renewable energy and effective waste treatment methods.

The genus Hyaloperonospora (Peronosporaceae; Oomycota) is an obligate biotrophic group that causes downy mildew disease on the Brassicaceae and allied families of Brassicales, including many economically relevant crops, such as broccoli, cabbage, radish, rape, and wasabi. To investigate the diversity of Hyaloperonospora species in northeast Asia, we performed a morphological analysis for the dried herbarium specimens collected in Korea, along with molecular phylogenetic inferences based on internal transcribed spacer rDNA and cox2 mtDNA sequences. It was confirmed that 14 species of Hyaloperonospora exist in Korea. Of these, three species, previously classified under the genus Peronospora, were combined to Hyaloperonospora: H. arabidis-glabrae comb. nov. (ex Arabis glabra), H. nasturtii-montani comb. nov. (ex Rorippa indica), and H. nasturtii-palustris comb. nov. (ex Rorippa palustris). In addition, finding two potentially new species specific to northeast Asian plants is noteworthy in support of the view that the species abundance of Hyaloperonospora has been underestimated hitherto.

The antioxidant activity of forty two kinds of salad vegetables grown in Korea was evaluated. Methanol extract of freeze-dried vegetable was assayed by radical scavenging activity using 1,2-diphenyl-2-picrylhydrazyl (DPPH) and Fe^{2+}$-catalyzed lipid peroxidation inhibition by TBA method. Total phenolics were determined colorimetrically using Folin-Ciocalteu reagent. The highest radical scavenging activity was expressed by perilla leaf, followed by dandelion leaf, red and green leafy lettuce, of which $IC_{50}$ was less than 0.10 mg/mL. Angelica leaf showed the highest inhibitory action for lipid peroxidation with $95\%$, and then dandelion leaf, water spinach, and perilla leaf inhibited over $80\%$. However, lettuce (Iceberg) and young Chinese cabbage exhibited the lowest antioxidant activity based on both assay methods. Highly positive correlations between antioxidative activities and total phenolics were observed (p < 0.001). The results suggested that salad vegetables, especially perilla leaf, leafy lettuce, dandelion or angelica, could be used for easily accessible sources of natural antioxidants.
