Red pepper, one of the major economic crops in Korea, is being affected by anthracnose disease caused by Colletotrichum acutatum. To control this disease, an antagonistic bacterial strain, Bacillus subtilis YGB36 identified by 16S rDNA sequencing, physiological and biochemical analyses is used as a biological control agent. In vitro screening revealed that the strain YGB36 possess strong antifungal activity against the pathogen Cylindrocarpon destructans. The strain exhibited cellulase, protease, amylase, siderophore production and phosphate solubility. In vitro conidial germination of C. acutatum was most drastically inhibited by YGB36 cell suspensions (10⁶ cfu/ml) or culture filtrate. Development of anthracnose symptoms was reduced on detached immature green pepper fruits by treatment with cell suspensions, and its control value was recorded as 65.7%. The YGB36 bacterial suspension treatment enhanced the germination rate of red pepper seeds and promoted root development and growth under greenhouse conditions. The in vitro screening of fungicide and insecticide sensitivity test against YGB36 revealed that the bacterial growth was not affected by any of the insecticides, and 11 fungicides out of 21 used. Collectively, our results clearly suggest that the strain YGB36 is considered as one of the potential biocontrol agents against anthracnose disease in red pepper.

Carnitine is considered a conditionally essential nutrient because dietary sources may become important under conditions which either reduce biosynthesis or increase urinary excretion of carnitine. Therefore, it is important to have a database for dietary analysis for carnitine content. Because there is limited data available for the carnitine content of Korean foods, this study was undertaken to analyze the total carnitine (TCNE) content of 146 commonly consumed Korean foods. TCNE concentrations were assayed using a modified radioisotopic method. Beef and pork contained 91.09 and 17.21 mg TCNE / 100 g weight, respectively. Fish and shellfish ranged from 0.28 to 24.87 mg TCNE / 100g weight. TCNE concentration in milk was 1.77 mg / 100 mL and cheese was 0.49 mg / 100 g weight. Cereals and pulses contained between 0 and 1.43 mg TCNE / 100 g weight. The TCNE concentration of most fruits and vegetables was between 0 and 0.7 mg 1100 g weight. However, mushrooms contained between 2.77 and 7.02 mg of TCNE / 100 g weight. Soy sauce, soybean paste and fermented red pepper soybean paste contained 1.05, 0.28 and 0.5 mg TCNE / 100 g weight, respectively. These results demonstrate that TCNE concentrations are high in meat, fish, shellfish and milk, but low or non-existent fruits and vegetables. However, mushrooms are a substantial source of vegetable derived TCNE. These data will be useful in establishing a database for determining the TCNE content of Korean diets.

The phenotypic traits of 63 Asian plum varieties were investigated for three years to select those with superior qualities for breeding. Eight morphological characteristics of the flowers and fruits (e.g., stigma position, fruit skin, and flesh color) were evaluated. Phenological characteristics (e.g., blooming time and ripening time) were also monitored. Being useful traits for breeding, fruit quality factors (e.g., fruit weight, skin color, flesh color, soluble solids content, and titratable acidity) were evaluated as well. The majority of the fruits were cordate (36%) and circular (23%) in shape. Approximately 78% of the varieties showed a red skin color, whereas 67% had yellowish fruit flesh. Fruit ripening occurred from June 28th to September 5th, spanning 69 days. The average fruit weight and soluble solids content were 77.2 g and $12.2^{\circ}Brix$, respectively. Regarding correlations among the characteristics, the most significant correlation coefficients were for the ripening time and fruit size parameters. Such information of Asian plum varieties will be useful for future breeding programs.

Since 2000, severe rots on aerial and underground parts of paprika( Capsicum annum L.) has occurred in most cultivation glasshouses throughout the country. Totally 169 isolates of a fungus were consistently isolated from the diseased plant tissues of fruits, stems, branches, and roots collected from 19 farms in six provinces. Anamorph stage of the fungus was identified as Fusarium solani based on morphological characteristics. However, the fungus readily produced sexual structure of perithecia on infected plant tissues and on agar medium. Since the fungus formed abundant perithecia by single isolate, it was considered as a homothallic strain of Nectria hematococn, the teleomorph of F. solani. Irregularly globose perithecia with orange to red color formed sparsely to gregariously on dead tissues of fruits and basal stems at the 3ate infection stage, which is a diagnostic sign for the disease. Abundancy of perithecium varied among isolates and they sized 125-220$\mu\textrm{m}$ in diam. Asci enveloping eight ascospores were cylindrical and measured 60-80x8-12$\mu\textrm{m}$. Ellipsoid to obovate ascospores are two-celled and measured 11-l8${\times}$4-7$\mu\textrm{m}$. Ascospores are hyaline, slightly constricted at the central septum, and revealed longitudinal striations that is a typical trait of the species. This fungus that has never been reported in Korea previously became a threat to paprika cultivation because of its strong pathogenicity and nationwide distribution.

The several sacrificial rites foods in east coast areas Kyungpook province, Pohang, Youngduk, and Uljin, were surveyed. For the anniversary menorial service, the food items in these reas were mainly rice(Bab'), soup(Guk'), stew(Tang'), fruits, neats and fishes, alcohol which are the typical food items for any other area in Korea. In this east coast area, the seaweed was used more often than in inner land area for this rite food. Four kinds of rice cake(Ddeok' or Pyun') were surveyed for this rite. For the baked food item(Geuk'), the fish squid and the Alaska pollack were used frequently for Geuk'. For the fruits dishes, 3 items were the basic. Tang' which was made with the various fishes, were used very frequently. For the religious memorial service for god to guard the household, the displayed food items were different from depending on the type of the god to guard the household, however, the general display of the food items was almost the same as in land area. For the winter sacrificial rite, the boiled rice(97%) and Bakpyun' was used mostly for the Ddeok'. For the Guk', bean sprout was used mostly, however, the seaweed soup was also used(7%). The fish Tang' was the most used one(35%). For young-deung-je', which implied th safe guard of the household, most of the food items are similar to those of the normal sacrificial rite, however, the fishes which were not fishy were used. The housekeeper arranged the rite to catch a large amount of the fishes and to hope the wellbeing of the household, Poong-yer-je is so called as Byul-sin-gud'(a practice of an exorciser). The food items for this Poong-yer-je' were almost similar to those of the winter sacrificial rite, however, Geulpyun' was mostly used for the Pyun'. In addition that, the red-bean Si-ruddock', Baekpyun', and Yung-ddock'(a dragon cake) were used for this rite, At the end of the sacrificial rite, Yong-ddock' was served to the dragon king which was believed in sea.

In 2014, Anthracnose symptoms were observed on fruit of pumpkin in Gangneung, Gangwon in Korea. The typical symptoms on fruit surfaces were circular lesions, brown, shriveled with salmon-colored spore masses on the spots. A fungal isolate was obtained from symptomatic on fruit and cultured on potato dextrose agar at 25℃. The color of the upper surface of the colony varied from white to gray with occurrence of salmon-colored conidial masses and was red to violet on the underside. The causal fungus of anthracnose isolated from the diseased fruits was identified as Colletotrichum fioriniae based on mycological characteristics and sequences of the internal transcribed spacer, glyceraldehyde-3-phosphate dehydrogenase, chitin synthase-1 gene, histone H3, actin gene, beta-tubulin gene region. Pathogenicity tests of the isolate were performed on pumpkin fruit by both wound and non-wound inoculation with conidial suspension (1×10⁶ conidia/ml) and incubated at 25℃. Lesions were observed on both wounded and non-wounded fruit of pumpkin after 7 days inoculation in only C. fioriniae. The pathogen was re-isolated from the lesions of inoculated fruits. To our knowledge, this is the first report of anthracnose on fruit of pumpkin caused by C. fioriniae in Korea.

In order to setup the diet guideline of five grains, five meats, five fruits, and five vegetables for the diseases of five organs, I reviewed the their tastes by comparing "Naekyeong" with "Euhakibmun", "Dongeuibogam". 'Ma(麻)' in "Naekyeong" means not a hemp, a ramie or a jute, but a sesame(胡麻;참깨). 'Maik(麥)' in it means both a barley(大麥;보리) and a wheat(小麥;밀). 'Guak(藿)' in it means bean leaves(콩잎), leaves of a red-bean(팥잎) or brown seaweed(海藻;미역). 'Gyu(葵)' in "Euhakibmun Jangbujobun(臟腑條分)" is a miswritten word for 'Welsh onion' caused by similarity of shape of word. Food of a salty taste according to five elemental arrangement in "Naekyeong" is really salty according to "Euhakibmun" and "Dongeuibogam". But a barley(大麥) and a wheat(小麥) of sour taste are bitter, a chicken of sour taste or hot taste is sweet, nonglutinous millet of sour taste is sweet, an apricot of bitter taste is hot, a sesame seed of sweet taste is sour, a nonglutinous rice of hot taste is sweet, and a horsemeat of hot taste is bitter according to them. There are two ways to recommend the food for diseases of five organs. One way is to promote or control the Qi(氣) of five organs according to "Somun(素問)" and "Euhakibmun Jangbujobun", the other way is to build up the Yin(陰血) of five organs according to "Yungchu(靈樞) five tastes(五味)". The two different ways are not contradictory to each other, but complement on the view point of their substances(體) or actions(用).

The purpose of this study was to investigate ash and mineral contents of agricultural products that are widely and specifically grown in Korea, including 23 fruits, 11 cereals and specialty crops, and 11 leaves and vegetables. Pre-treatment of mineral was performed by microwave method. Mineral contents were analyzed by Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) and Inductively Coupled Plasma Spectrophotometry Mass (ICP-MS). Ash contents ranged from 0.20 to 0.69 g/100 g in fruits, 1.62 to 3.80 g/100 g in cereals, and 0.28 to 2.93 g/100 g in leaves and vegetables. Among the 45 samples, the highest contents of ash were found in quinoa (average 3.80 g/100 g), the highest contents of calcium (Ca) were found in Hansan ramie leaves (average 894.79 mg/100 g), the highest contents of phosphorus (P) were found in yellow amaranth(average 661.88 mg/100 g), the highest contents of potassium (K) were found in quinoa (average 1,455.38 mg/100 g), the highest contents of magnesium (Mg) were found in red amaranth (average 434.02 mg/100 g), the highest contents of molybdenum (Mo) were found in moringa (average $482.50{\mu}g/100g$), and the highest contents of selenium (Se) were found in apple mango(average $23.67{\mu}g/100g$).

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 investigated whether socioeconomic differences affect fruit and vegetable (FV) consumption with respect to total intake and intake of various FV subgroups. Our study included 6667 adults aged 40-64 years who completed a dietary survey in the fourth Korean NHANES (2007-2009). FV intake was estimated from 24-hour recalls and food frequency questionnaires. Differences in FV consumption related to educational attainment were analyzed according to different nutritional categories of FV. Both men and women in the low-education group had the lowest intake of total FV and total fruits, and women also had the lowest intake of total vegetables. Also lowest in this group was consumption of mushrooms and vegetables (excluding kimchi) among men, and cruciferous and allium vegetables (excluding Chinese cabbage and radish) among women, while kimchi consumption was the highest in this group. Additionally, an association between educational level and intake of citrus fruits was evident among men. Adults in the low-education group consumed less carotene-rich FV, red fruit and/or vegetables, and dark-green leafy vegetables, fewer total vegetable dishes, and fewer types of fruit than in other groups. Men in this group had the lowest intake of yellow/orange fruit and/or vegetables, and women consumed the least folate-rich FV. There is a clear association between educational attainment and FV intake with regard to total intake, and to specific nutrients, bioactive compounds, colors, and variety.
