Indoor airborne bacterial and fungal concentrations were examined at classrooms and corridors of 3 elementary schools in Ulsan. Airborne microorganisms were collected with an impaction-type air sampler using plate count agar and dichloran rose bengal chloramphenicol agar. During the semester, concentrations of bacteria ranged $168{\sim}3,887 MPN/m^3$ at classrooms and $168{\sim}6,339 MPN/m^3$ at corridors, while those of fungi ranged $34{\sim}389 MPN/m^3$ at classrooms and $91{\sim}507 MPN/m^3$ at corridors. The bacterial concentrations showed larger variations between situations and schools compared to those of fungi. When airborne bacteria were isolated and identified, 84% were observed as Gram-positive, and Micrococcus spp. was the most abundant group with 61% of tested isolates, followed by genus Staphylococcus with 10%. The Micrococcus spp. isolates, of which 75% were identified as M. luteus, appeared to be from human origins. The protective pigments and substantial cell wall of Micrococcus may provide selective advantage for their survival in the air. We also isolated and identified 15 genera of filamentous fungi. The most common culturable fungi were Cladosporium, Aspergillus and Penicillium, and these 3 genera were 69% of fungal isolates. Genus Stachybotrys, of which S. chartarum is a well known producer of many potent mycotoxins, was also detected from one of the schools. further systematic studies are necessary with an emphasis on species identification and mycotoxin production of isolated fungal genera, including Aspergillus, Penicillium, and Stachybotrys.

This study examined the dietary life by residence type of 409 university students (198 male and 211 female) in Chungnam They were divided into five groups according their residence: living in the family home a short distance from the university, living in the family home a long distance from the university, boarding house, self-boarding house, and university dormitory. In this study, the intake of food and nutrients and health, and dietary behaviors of each group were investigated through two-week questionnaire. The average age, height, weight, and BMI were 21.4, 175.3 cm, 68.9 kg, 22.3 in males, and 19.9, 162.3 cm, 53.3 kg, 20.2 in females, respectively. Dietary attitude of the students living in home was higher than that of the other student groups. The rate of breakfast intake and the frequency of eating 10 food items of subjects except processed food of self-boarding house group were lower than those of the other 4 student groups. These results suggest that university students of self-boarding house might have low ability of meal management and more reasonable nutrition education is needed for desirable food behaviors.

Changes of Harbors` Functions and the Urban Structure at Marseille in the Nineteenth-Century Kim, Na-young·Hyun, Jae-youl [Abstract] Marseille, the typical sea-port city of Mediterranean France, was the most representative port of French Colonial Empire in the 19th century. Studying on Marseille of that time would contribute to the typological understandings of the sea-port cities in the period of Imperialism. This article aims to present a type of development which a sea-port city of the colonial empire could take, by interrogating the changes of harbors` functions and the urban structure of Marseille in 19th century. The consequent findings are as follows. First, the population of Marseille had sharply risen from 1830 on, and increased three times from 1820 to 1870s. This increase of population marked the economic growth of the city. Carrying capacity of vessels entering the port of Marseille rising five times in 1825-1870 shows the scale and the process of this growth. However, this economic growth had attributed to the colonial expansion of France launched from 1830 on. Second, according to the rising traffic of port, the harbors of Marseille had been expanded to the north of old port(Vieux-Port) since 1840s. With their expansion, the harbors` functions of Marseille had changed simultaneously, adding the industrial function to the traffic and distributive functions. Second, the industrialisation of Marseille also occurred in association with these circumstances. As a result, new and factory industries, such as sugar refining, oily industry, soap industry, machinery manufacture and foundering, etc. were thriving in the city and its suburbs. However, the material sources of these industries were from the French colonies, and, thus, the industrialisation was highly dependent on the supply from colonies. This is a remarkable feature of the Marseille`s industrialisation, and it can be that this industrialistation was a type of development which the sea-port city of the colonialist Empire would take. Third, the changes of harbor`s functions and the industrialisation had caused the transformation of urban structure of Marseille. Most notable transformation was the extension of city scale. Also, the appearance and shape of city had changed geometrically and orderly with the constructions of the various official buildings and monuments through the French Second Empire. Fourth, withstanding the extensions and changes of urban structure, the social character of neighborhood did not change so much at same time. Unlike with Paris where the neighborhood had been divided sharply between the bourgeoisie and the working-classes as a result of Haussmanisation, Marseille witnessed the loose line of division between the higher and lower classes, except with the ``old city`` in the north of old port and the higher classes` neighborhood in the southeast of it. However, one another consideration of social character was the reduction of proportion of natives in the neighborhoods. Throughout the mid-century, numerous immigrants fluxed into Marseille as the skill and unskill workers, and they gradually spread into all of the neighborhoods in the city.

This study was conducted to investigate the quality characteristics of the bread with red ginseng powder(RG). Four different powder concentration levels of 0, 3, 6, and $9\%$ were added to flour to make the bread. The appearance, pH, water holding capacity, specific volume, color, texture, and sensory properties were analyzed. pH of bread with RG had no difference according to the content of the red ginseng powder. The specific volume of the bread containing $0,\;3,\;6\%$ were bigger than that of the bread with $RG-9\%$. The water holding capacity of the bread with $RG-9\%$ was the highest. As the amounts of RG increased, L-values of the bread crumb were decreased and a- and b-values were increased. As a result of texture measuring by texture analyzer, hardness and gumminess were not affected by the addition of RG. Also, springiness, cohesiveness, and chewiness were not significantly different among the control, $RG-3\%\;and\;RG-9\%$. In sensory evaluation, color, flavor, taste and overall acceptability in the bread with $RG-9\%$ were significantly lower than the control and the other groups. On the other hand, the best result for sensory characteristics showed when red ginseng powder at $3\%$ level was added to the bread.

The purpose of this study was to provide basic information need to promote early childhood's growth with balanced diet and preferable dietary attitude by observing the provision of food service management in kindergarten in Daejeon. We researched the dietary life of full- and half-day program children and their mothers. A questionnaire survey was conducted with 392 children attending kindergarten and their mothers. The questionnaire items examined general characteristics, dietary life, dietary behavior, frequency food intake etc. The results of the survey were as follows. The frequency of breakfast intake of the half-day program children and their mothers was higher than that of the full-day program children and their mothers. Most of the children had an unbalanced diet about soybean, kimchi, and vegetables, whereas their mothers had an unbalanced diet about processed food In general, the half-day program children showed higher scores than full-day children for the items of the dietary behavior of kindergarten. The dietary attitude and nutrition attitude scores of the half-day program children and their mothers were higher than those of the full-day program children and their mothers.

Serum pepsinogen (sPG) is a marker of gastric mucosal atrophy, a condition that has been associated with an increased risk of gastric neoplasia. A low sPGI level and a low PG I/II ratio have been associated with severe gastric atrophy, and are frequently found in gastric cancer. Because the prevalence of gastric cancer is high in Korea, it would be convenient if a good biomarker for gastric cancer were developed. Two studies recently investigated the efficacy of sPG along with Helicobacter pylori (H. pylori) as a screening tool for gastric cancer. In these studies, sPG was measured using a Latex enhanced Turbidimetric Immunoassay. We found that H. pylori IgG status, age and gender were associated with serum pepsinogen levels. Thus, to increase the ability of the PG I/II ratio to detect atrophic gastritis, the cutoff value for the PG I/II ratio should be stratified according to the H. pylori IgG status. In addition, a PG I/II ratio ($\leq3.0$), which has been widely used as an international standard for gastric cancer, was found to be a reliable marker for the detection of gastric dysplasia or gastric cancer, especially of the intestinal type. The efficacy of the test in Korea was lower than the efficacy in Japan. However, the detecting power of a PG I/II ratio ($\leq3.0$) was significantly increased in the presence of H. pylori. The ratio together with H. pylori psotivitiy could provide a means of identifying persons at high risk of developing gastric cancer in Korea.

Projection pursuit classification tree uses a 1-dimensional projection with the view of the most separating classes in each node. These projection coefficients contain information distinguishing two groups of classes from each other and can be used to calculate the importance measure of classification in each variable. This paper reviews the variable importance measure with increasing interest in line with growing data size. We compared the performances of projection pursuit classification tree with those of classification and regression tree(CART) and random forest. Projection pursuit classification tree are found to produce better performance in most cases, particularly with highly correlated variables. The importance measure of projection pursuit classification tree performs slightly better than the importance measure of random forest.
