From sludge of S municipal wastewater treatment plant in Busan, Korea, we isolated the denitrifier DN-9 which showed the ability of denitrification under aerobic conditionby the color change and gas formation in liquid culture with Giltay medium. The isolated strain was identified as Pseudomonas sp. DN-9 on the basis of the morphological, physiological, biochemical and nucleotide sequence analysis of l6S rRNA. The isolated strain, Pseudomonas sp. DN-9, has cytochrome $cd_1$, nirS of nitrite reductase. By the co-existance of additional ammonium and nitrate ion, the strain was not affected largely on growth in SL series broth. It seemed the result of denitrification. Although Pseudomonas sp. DN-9 has a good nitrate reduction activity under aerobic condition, the activity is less than Pseudomonas stutzeri in same cultivation condition. However, Escherichia coli had little the activity of aerobic denitrification and Pseudomonas putida showed lower activity of aerobic denitrification than Pseudomonas sp. DN-9 and Pseudomonas stutzeri in this study.

The diurnal changes of chlorophyll fluorescence and antioxidative enzyme activity were investigated in the leaves from four subtropical plant species (Crinum asiaticum var. japonicum Bak., Osmanthus insularis Koidz., Asplenium antiquum Makino and Chloranthus glaber Makino) under the natural habitats in summer and winter. The intensity of chlorophyll fluorescence was lower in O-, I-, J-, P-steps of O-J-I-P transient in winter than summer, and prominent diurnal change was not found in the fluorescence intensity of four subtropical plant species in winter. The activity and isoenzyme pattern of SOD and catalase did irregularly change seasonally and diurnally in four subtropical plant species. In contrast, the peroxidase activity and isoenzyme pattern was different depending on plant species and growth seasons; The activity increased slightly more in winter than in summer in four subtropical plant species, and several isoenzymes appeared in the leaves from C. asiaticum var japonicum, O. insularis and A. antiquum in winter.

This study was performed to evaluate the asbestos exposure levels and to calculate excess lifetime cacer risks(ELCRs) in asbestos-containing buildings for maintenance and management. The range of airborne asbestos concentration of 33 buildings was 0.0018 ~ 0.0126 f/cc and one site exceeded indoor air-quality recommended limit 0.01 f/cc. And ELCRs based on US EPA IRIS(Integrated risk information system) model are 1.5E-06 ~ 3.9E-05 levels, and there was no site showed 1.0E-04 (one person per million) level or more, and 11 sites showed 1.0E-05 (one person per 100,000 people) level or more. To prevent the release of asbestos fibers, it needs operation and maintenance of asbestos-containing building materials, and there are some methods such as removal, repairment, enclosure and encapsulation. In conclusion, a risk-based air action level for asbestos in air is an appropriate metric for asbestos-containing building management.

This study was designed to find out clothing weights and clothing practice of elementary school children and their mothers and to investigate the correlation between clothing weights of the children and those of their mothers and to investigate the correlation between clothing weights and physical fitness of the children. RESULTS : 1. Total clothing weight of elementary school children was heavier than that of their mothers. 2. The results analyzed by sex and age of the children were as follows. Correlation was little recognized between lowerwear, underwear weights of the 6 year old girls and underwear weight of their mothers and between upperwear weight of 10 year old girls and underwear weight of their mothers. 3. In case of the children who made a clothing decision with their mothersm, correlation was recognized between total clothing weight of the children and total clothing, underwear, lowerwear weights of their mothers, and between upperwear weight of the children and upperwear weight of the children and upperwear, total clothing, underwear and outerwear weights of their mothers, and between outerwear weight of the children and lowerwear weight of their mothers. 4. Physical fitness had partly a negative correlation with the clothing weights in case of the boys, while not the girls. As a reslult, clothing weights of elementary school children were related to thermal sensation of their mothers.

The completely answered questionnaires were analyzed for the nutrition knowledge, food habits, value orientation, and the sources of nutrition information of housewives of 20's to 40's. The subjects had a high level of perceived knowledge, that is the knowledge that each subject believed she hadm but the accuracy of the knowledge was only 51.6%. The mean nutrition knowledge score was 6.63 out of possible 15 points, and food habit score was 5.31 out of 10 points. Most of the subjects belonged to "Good" to "Fair" food habit group, which is considered to be relatively good. With increasing age and decreasing level of education, the percent of perceived knowledge and accuracy, and nutricion knowledge score were getting lower. However, the food habit score was getting higher with increasing age. This suggests that food habit was dependent more upon the length of married life than the nutrition knowledge in housewives. The corelation between nutrition knowledge score and food habit score was low. The economic area was the most concerned area of the subjects, followed by health and social. The scores of utrition knowledge and food abits of the subjects who ranked the health the highest were not different from those of economic and social. TV, radio, newspapers, and magazines were the most important sources of nutrition information.

The purpose of this study was to analyze effects of the mother's child-rearing patterns on children's academic achievement with respects to ‘understanding of family and work’ area in Practical Arts Education related to the 7th revision on the Curriculum of the Elementary School. The questionnaire was used for the survey. The subjects were 200 mother-child (total of 400) randomly chosen from 4 elementary schools in Seoul. Data were analyzed by frequencies, percentages, averages, standard deviations, Pearson's correlation coefficients, t-tests and one-way ANOVA's using the SPSS/PC＋ program. The results of this study were summarized as follows : The correlation between income in their home and their children's academic achievement did not analyze because of the omitting record in their questionnaire. The relations between the patterns of mother's child-rearing and children's academic achievement by children's sex and by grade were examined. But in this study, these relations scarcely have significant differences between the children's academic achievement and their mothers' child-rearing pattern except between being significant reject-sanctions type of mothers' child-rearing and the children's academic achievement. However, the child-rearing patterns of mothers which children and their mothers think were similar, then the high correlations were found between their patterns.

A military uniform has two basic characters. One is functionality for field warfare and the other is decorativeness to express dignity and power to maintain systematic organization. For these purposes, the military uniform is maximizing its effects on functionality and decorativeness on each aspects of material, color, dignity, item, military ornaments and accessories. During wartime, the military uniform improved its functionality and gave much influence on normal clothing at the same time either directly or indirectly. Military look became more diverse. In a mood for the end of century and inflated material civilization, and with nostalgia for the fast, mixed styles of fast, presents and future have come out in variety. In Street Fashion, there are many alternative trends to meet diverse desires of teenagers, and the military look has been steadily favored. The functionality and the decorativeness of military look would have met fashion sense and taste of younger generations pretty well. First, teenagers are active, and the practical materials and functional designs of military style applied to their clothes. Second, they prefer challenging and creative styles, and the decorative elements of military clothing for the colors, patterns, accessories have been applied to they clothing. We may need to understand their culture and emotion more closely and help them enjoy sound and beautiful clothing culture.

We find ourselves living in a post-human era when technology and images coexist with humans. A cyborg, a combination of an organic body and a machine could be called a human fused with a machine. It could be understood as a new species where humans and machines have combined rather than simple protoplasm or an organic body. The purpose of this study is to demonstrate that a concept of a body in post humanism era is finding expression in fashion illustration through cyborg images. The concepts of post humanism and cyborg are analysed by means of research into literature and characteristics in which cyborg images as post humans are expressed through art, and images of a cyborg body in fashion illustration and their meanings are explored with the foregoing as a framework of reference. Cyborg image reflects new images and concept of a human in post humanism. The cyborg body images in fashion illustration are expressed through the addition of mechanical images, digital virtual body, monster image by means of hybrid combination, distorted physical transformation and fragmented body and body absence. And cyborg image in fashion illustration shows the extension of body concepts through the technology and uncertain and ambiguous identity.
