In this study, ultrasonographic evaluations were made after experimentally induced ascites in dogs. Ultrasonographic evaluation allowed to identify the earliest fluid accumulation between the spleen and the left kidney after the administration of 0.9% normal saline at 8 ml/kg into the abdominal cavity in dogs. Ultrasonographic finding were observed in order between the spleen and the left kidney, the liver, the pelvic cavity. It is considered that the most adequate pare f3r the early detection of ascites is between the spleen and the left kidney, and the least amount of detection fluid is 8 ml/kg in dogs.

Objectives: The purpose of this study was to evaluate food hygiene and safety knowledge, attitudes, and practices (KAP) among the elementary school children, and furthermore, to explain the interrelations among these three variables. A second purpose was to compare gender differences of KAP. Methods: A self-administered, structured questionnaire was designed and completed by 376 elementary school children. A five-point Likert scale with twenty questions was used to gather information. Data was analyzed by frequency analysis, Pearson's correlation and analysis of variance or Student's t-test. Results: Children generally had good knowledge of food hygiene and safety, and knowledge of children was superior to the attitudes and also to their practices (p < 0.05). The attitude score was mediated between knowledge and practice scores. Significant differences (p < 0.05) were found between boys and girls in an item of knowledge, three items of attitudes, and six items of practices. A significant positive correlations were observed between knowledge and practices (${\gamma}$ = 0.70, p < 0.001), and between attitudes and practices (${\gamma}$ = 0.45, p < 0.001), as well as between attitudes and practices (${\gamma}$ = 0.51, p < 0.001), revealing that increased knowledge and even attitudes toward food hygiene safety could result in positive change in practices or behaviors. Conclusions: The results of this study indicate that despite good knowledge and attitudes of children, their practices toward food hygiene and safety are not acceptable. Gender differences in practices were highlighted. In order to create effective educational interventions on the food hygiene and safety of children, a better understanding of their awareness and the required related information is necessary.

The number of food establishments selling raw and convenience foods are increasing in Korea, and people enjoy purchasing and eating foods at these shops. However, there are only a few reports on the temperature control of the refrigerators and freezers at retail food shops. This study was performed to investigate the temperature control of refrigerators and freezers in retail food shops in Daegu. The survey was carried out from July 20 to August 30 in 2001. The trained surveyors visited the twenty retail food shops (four department stores, eight marts/supermarkets and eight convenience stores) in the 8 major areas of Daegu and inspected the temperature control of 48 refrigerators for dairy products, fruits & vegetables, and rolled rice & sandwiches, and 52 freezers for ice cream & sherbet, frozen food, and frozen fish. The percentage of the refrigerators, and freezers with unsafe temperatures higher than the recommended safe temperature (10℃ for refrigerators, and -18℃ for freezers) was 42%; 45.8% in refrigerators; 38.5% in freezers. On an average, the bigger the size of the shop, the better than the other freezers. On the other hand, the temperature control of refrigerator for fruits & vegetables was the worst because they were usually open. Actual temperatures in the refrigerators and freezers were found to be significantly higher than the reading on the thermometers attached to the refrigerators and freezers(p<0.05). These results indicate that temperature control of refrigerators and freezers at retail food shops should be monitored several times each day, and should have strict inspection. There should be more detailed legal standard and specification for temperature control of refrigerators and freezers at retail food shops to prevent foodborne illness from unsafely stored food.

A porous photocatalyst concrete filter was successfully produced to remove NOx, by mixing TiO2 photocatalyst with lightweight aerated concrete. Ultra Fine Bubbles were used to form continuous pores inside the porous photocatalytic concrete filter, which was mixed via a bubble generation experiment. The optimal mixing condition was determined to be with 4% of the bubble generation agent B. NO removal specimens were prepared for various photocatalytic loading conditions, and the specimen containing 3% P-25 removed NO at a concentration of 1.03 μmol in 1 h. The NO removal rate of the porous photocatalytic concrete filter prepared in this study was 10.99%. This photocatalytic filter performance was more than 9 times the amount of NO removed by a general photocatalytic filter. The porous photocatalyst concrete filter for removing NOx developed in this study can be applied to various construction sites and the air quality can be solved by reducing NOx contributing to the formation of fine particles.

It is important to study the usage of language shown in the expression and structure of Hyang-ga because it belongs to a lingual art. The interpretations of Hyang-ga is not perfect yet. However, literary study can help to interpret Hyang-ga and clarify the identity of it. Therefore this paper is to research not only the process that the subject of shaman song developed into the poetic subject by studying Won-ga but also the appearance of changing the shamans objects into poetic materials and the process of forming emotion-centered poetic lyricism. In conclusion, this one aims to clarify the fact that Won-ga had been lyric poetry created by the lyric expression through the appearance changing the form of shaman song into the one of poetry developing the power of incantation into the one of expression.
