A nutrition survey of 209 children, 6 to 13 years old, in the namgok elemetnary school at Namsamyun, Yongin-gun, Kyonggi province, was undertaken in July of 1987, to investigate dietary and nutritional status. Mean value of hight was 98% of the Korean standard established by the Korean Standards Research Institute. However, in these terms, 7.7% of the subjects were proven to be short, mean value of weight was 94.5 of the Korean standard. However, in these terms, 9.3% of the subjects were proven to be moderatly underweight ; whereas 10.4% of the subjects were proven to be over weight. By the WHO criterion, 18.4% of the subjects showed lower figures of hemoglobin than anemic level of 12gm%/이. Mean urinary urea nitogen/creatinine ratio was 9.1$\pm$5.0 Carbohyudrate provided 68% of total energy intake ; protein accunted for 13% ; fat provided 19%. Energy intake was divided among breakfast, lunch, dinner and snacks in a percentage ratio of 22 : 44 : 24 : 13. The survey clarified that the elementary school feeding largely supplemented the inadequate intake of these chidren at home.

Enterobacter sp. B54 inhibited growth of the fungus Phytophthora capsici on potato dextrose agar (PDA). Three mutants with antifungal activities (denoted M54-47, M54-113, and M54-329) which were lost or increased, through Pl::Tn5 lac mutagenesis, were used to isolate genes responsible for fungal inhibition on PDA. Two clones were selected from the partially EcoR1-digested genomic library of the wild-type strain by probing with genomic flanking sequences of each mutant. We have isolated a 20-kb EcoR1 genomic DNA fragment from this strain that contains genes involved in hyphal growth inhibition of P. capsici on PDA. Subcloning and expression analysis of the above DNA fragment identified a 8-kb region which was necessary for antifungal activities. A 8-kb HindⅢDNA fragment covers three genomic loci inserted by Tn5 lac in each mutant. This suggested that all genes which are related to antifungal activities might be clustered in simple forms of at least 5-8 kb sizes.

Infected sweet potato (Ipomoea batatas) showing symptoms of sunken veins, stunting, mosaic, and mottling were collected from Gimje, Cochang, Iksan, and Haenam provinces in Korea. Electron microscopic (EM) observation of the infected tissue revealed rod and filamentous rod type virus particles of various lengths. Western blot analysis of the protein samples extracted from infected sweet potato and partially purified virus identified the isolates as Sweet potato feathery motile virus (SPFMV), Sweet potato latent virus (SwPLV), and Sweet potato chlorotic stint virus (SPCSV). Sweet potatoes were occasionally infected with more than one of these viruses. This is the first report of SwPLV and SPCSV in Korea.

This study was undertaken to investigate intake and consumption behavior of dairy products in college students in order to identify a better way to increase milk consumption. This survey was carried out through questionnaires. The subjects were 307 college students in ChungJu. A total of 98.3% students thought milk as good for health but only 21.5% of them drank it everyday. Most students reported drinking milk two to three times a week. Male students reported drinking milk for drinking, whereas females students for nutrition. College students preferred flavored milk rather than plain milk. Students preferred the drink-type yogurt among the dairy products. The major reason for drinking fermented milk was taste. After drinking the fermented milk, 39.1% of female students thought that fermented milk could prevent constipation. Most students thought that better taste and quality of milk and milk product would increase their consumption.

Root colonization by the rhizobacterium Pseudomonas chlororaphis O6 in Arabidopsis thaliana Col-0 plants resulted in induced tolerance to drought and salinity caused by halide salt-generated ionic stress but not by osmotic stress caused by sorbitol. Stomatal apertures decreased following root colonization by P. chlororaphis O6 in both wild-type and ABA-insensitive Arabidopsis mutant plants. These results suggest that an ABA-independent stomatal closure mechanism in the guard cells of P. chlororaphis O6-colonized plants could be a key phenotype for induced systemic tolerance to drought and salt stress.

The characteristics of agricultural water rights were examined for the national rivers in Korea. We suggest that the national rivers could according to the actual management organization of agricultural water right be categorized into national management rivers KOWACO(Korea Agrcultural & Rural Infrastructure COrporation) management river. The agricultural water right between the national and KOWACO management rivers have different characteristics for irrigation period permit procedure water charge and type of water right. The agricultural water rights are granted in the natural discharge less than reference droughty discharge for most of national management rivers and in the developed discharge for the KOWACO and KARICO management rivers. The current system of agricultural water rights is complicated inconsistent and incapable of coping with unusual drought and therefore it needs to be improved.

This study was undertaken to assess the school flood service management and its perception by dietitians. Questionnaries were developed and answered by 162 dietitians in elementary schools in Chollanam-do. The duration of the flood service system was the longest in remote areas followed by rural and urban areas. The average number of persons served a day was 680 per dietitians. More than three schools were supervised by 52.4% of dietitians. Lack of facilities, including restrooms for the flood service personnel and storage compartments for convenience products were indicated. Regardless of the type of school flood service system, the dietitians pointed out that they urgency needed gas fryers, gas griddles and vegetable cutters, which would be helpful in preparing fried flood for the students. Despite the dietitians' eagerness to teach nutritional education, 80.9% of the respondents did not provide nutritional education to the students, because of the lack of class roomtime. It was suggested that the teaching nutritional education by dietitians was desperately needed for the improvement of health and the nutritional status of school children.

The purpose of this study was to evaluate the effect of vegetation on the cutting slope applied by vegetation system in the whole land. The engineering characteristics of slopes were investigated using the face mapping and physical tests. From the statistical methods, a relationship between a geologic stratum and degree of covering was independent. Therefore, the afforestation of slope was affected more by condition of vegetation as direction and opening of joints, and a topsoil state than by conventional classification of layer. It was concluded that the adjustable vegetation on the slope considering condition of geometric shape of slope, joint data and spontaneous type could make useful early afforestation.
