  • This study was conducted to develop a food frequency questionnaire for an epidemiological study of dietary patterns and nutrient intake among Koeran American. A random sample of 101 Korean Americans between the ages of 17 and 71 residing in New York and New Jersey was interviewed by the method of 24-hour dietary recall. The foods Korean Americans consumed most frequently were rice (91% of the population), kimchee (81%), coffee(59%), bread(49%), apple(45%), bean sprouts (33%), milk (30%), dried anchovies (27%), eggs(27%), juice (26%), bulgogi, and soybean paste soup (24%, equally. The classification of food items standardized portion sizes were according to both Block's questionnaire and the standardized portion sizes by the Korean Nutrition Association. The value of this food frequency questionnaire is that it can accurately estimate dietary food patterns and nutrient intake among Korean Americans for epidemiological studies. It could also potentially be modified to study the relationship between specific diseases and food intake in the future.

  • The purpose of this study was to investigate of the dietary life and nutritional status of the Buddhist priests. Dietary life, the state of prepare a meal and menu are carried out through the questionnaire and the nutritional status is carried out through the analysis of the constituents of the blood. The results of this study can be summarized as follows. 1. The traditional temple's foods undergo a change with the variety and westernization of dietary life. 2. Buddhist priests take a carbohydrate centered meal and the intake of protein and lipid is tendency to lack, but the intake of vitamin and mineral is sufficient with various vegetables. 3. The content of the lipid compoents and glucose of blood are low and they are free from the danger of geriatric diseases but the content of triglyceride is very higher than the healthy general adults. Therefore it is necessary to improve the nutritional status of the buddhist priests with decrease the intake of rice and increase the various side dish and to develop the standard menu for the Buddhist priests.

  • Rice is the primary main dish of Traditional Korean diet. Although there have been changes in food consumption and nutrient intake among Koreans, traditional dietary pattern is stil dominant among Koreans. Traditional Korean diet has emphasized breakfast, which is the most frequently missed meals in Korea today but important for daily work performance and health. Compared to diets of the U.S. and Greece, Korean diet is high in carbohydrate and low in fat and cholesterol due to low intake of meat. Koreans also consume large amount of plant food, which makes fiber content of diet to be high. However fruit and milk consumption tends to be low in Korea. Koreans use fermented food, including kimchi, very frequently as well as foods cooked and consumed at high temperature and over direct fire. Traditional cooking methods are time consuming which limits the usage among modern city dwellers with working women. Despite the strengths of traditional Korean diets in reducing risk factors of chronic diseases, preservation of the tradition in modern Korean society requires special attention and efforts to make them more adaptable to contemporary life styles.

  • ;Bacterial blight caused by Xanthomonas oryzae pv. Olyzae is one of the most important diseases of rice. Host resistance, which relies on single, dominant resistance genes, is the only reliable method to control the disease at present. Pathogenic variation of the bacteria has been shown to follow the deployment of resistance genes in commercial cultivars. Information on the factors and the mechanisms for genetic variation of this pathogen is limited. Further, we have no clear evidence of whether population variability is due to sexual recombination or to variation introduced by mutations or intragenic recombination in a clonally maintained population.(omitted)itted)

  • Biocontrol is playing a more and more important role in plant disease management. Evidences show that there are optimum prospects for people to apply biocontrol approach to control plant disease or to study the mechanism of antagonism.“The study of Antagonistic Protein of Bacillus spp.to Xanthomonas oryzae pv. oryzae”has been worked in our laboratory since 1986. One hundred and thirty antagonistics bacteria were screened out, most of them belonged to Bacillus spp., and showed very strong inhibitive effect to various plant pathogens. Nine antagonistic proteins (peptides) were purified (P11-I, P11-II, B8, B826-I, B826-II, A30-I, A30-II, G35). Two antagonistic protein related DNA fragments (B826-I, A30-II) were cloned and sequenced. B826-I DNA fragment composed by 905 bp, and it contained two ORF encoding 95, and 54 amino acids, respectively. By using Rifr and Kamr as the selective markers, we found the bacteria could colonize on rice leaf for at least 40 days. In greenhouse the antagonistic bacteria showed certain degree of control efficiency.

  • The efficacy of formulated Trichoderma harzianum-based Tricho-compost, seed treatment with Tricho-inocula, and chemical fungicide Provax 200 WP against foot and root rot diseases of wheat caused by Sclerotium rolfsii was tested in the pot house and in the research field of Plant Pathology Division, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. Tricho-compost was prepared with a mixed substrate of cow dung, rice bran, and poultry refuse colonized by T. harzianum. Seedling mortality of wheat was significantly reduced by the Tricho-compost, Tricho-inocula, and Provax 200 WP both in the pot house as well as in the field experiments. The yield of wheat was sharply increased over the control due to the T. harzianum formulations and Provax 200 WP. Among the treatments, soil application of Tricho-compost was more efficient in reducing seedling mortality and accelerating plant growth with an increased yield of wheat with S. rolfsii-inoculated pot cultures and field experiments.

  • Isotianil is a novel fungicide which induces systemic acquired resistance in plants. It has excellent preventive effects as low dosages against rice blast which is one of the most serious diseases in rice. The Maximum Residue Limit (MRL) of Isotianil in republic of korea was set to 0.1 mg/kg in rice, so it is necessary to determine levels of Isotianil residues in agricultural commodities for controlling food safety. Therefore, The purpose of this study was to develop analytical method for the determination of isotiical residues in agricultural commodities using GC-NPD/MSD. Isotianil was extracted with acetonitrile from apple, chinese cabbage, hulled rice, mandarin, pepper, and soybean. The extract was diluted with saline water, and then dichloromethane partition was followed to recover this fungcide from the aqueous phase. A solid phase extraction with Florisil cartridge was additionally employed for final clean up. Isotianil was analyzed and quantitated by GC-NPD and confirmed by GC-MSD. Average recovery of Isotianil ranged from 70.0 to 103.9% in six representative agricultural commodities with relative standard deviations less than 10%, and limit of quantification (LOQ) was 0.05 mg/kg.

  • Throughout year 2015 to 2016, 101 proso millet and 200 sorghum samples were collected from five provinces in South Korea. The samples were subjected to paired-end RNA sequencing and further analyzed by RT-PCR. The results indicated that Rice black-streaked dwarf virus (RBSDV) was detected from sorghum collected in Gyeongsang province. The other four viruses, including RBSDV, Rice stripe virus (RSV), Barley virus G (BVG), and Cereal yellow dwarf virus (CYDV), were detected from proso millet. Among four viruses, both RSV and RBSDV were identified high frequency from proso millet collected from Gyeongsang province. Otherwise, BVG was nearly equally identified from five provinces, suggesting that the virus was supposedly widespread nationwide. RBSDV was first identified from both proso millet and sorghum in South Korea. The other virus annotated CYDV identified proso millet was shown to have relatively low identities compared to CYDV previously reported, suggesting that the virus might be new member of Polerovirus.

  • This study was conducted to evaluate suppressive effects of black rice aleurone layer extract (BRE) on body fat, serum lipid, and hormone levels in ovariectomized rats. The rats were divided into five groups (n=8/group): sham operated group (S); ovariectomized control group (OVX); ovariectomized group treated with isoflavone 10 mg/kg B.W. (IF); ovariectomized group treated with BRE 30 or 90mg/kg B.W. (BRE-30 or -90). High fat diet (45% calories from fat) was fed to all rats for 12 weeks. Body weight gain, body fat weight, and adiposity index increased in the OVX group, but they significantly decreased in IF or BRE supplementation. Serum triacylglycerol and leptin levels decreased in BRE groups while serum adiponectin level significantly increased compared to that of the OVX group. Hepatic total lipid, triglyceride, and cholesterol levels increased in the OVX group, but they decreased in BRE supplementation (p>0.05). These data suggest that black rice aleurone layer may be a useful food source to decrease obesity and its related diseases by modulating lipid metabolism in estrogen-deficiency model.
