Due to the low biodegradability of dyes, conventional biological wastewater treatment systems are inefficient in treating dye wastewater. Various white-rot fungi were investigated for the decolorization of six industrial dyes (reactive blue 5, reactive blue 16, reactive black 5, acid black 52, reactive orange 16, and acid violet 43). Among ten fungi, T. versicolor KCTC 16781 was selected as a testing strain because this had the best performance of decolorization for six dyes from the results of the solid culture experiments. In liquid culture medium, T. versicolor KCTC 16781 decolorized over 96% of six dyes for 48 hrs. Laccase started to produce in the early stage of the culture, and showed the highest peak value of 2.3 U/mL in 24 hrs. Enzyme activity remained constant until the end of culture. Fungal decolorization is a promising alternative to replace or supplement present treatment process.

The purpose of this study was to quantitatively examine the biomechanical variables of Fouette turns for expert and beginner ballet dancers and to determine the difference in the variables between the two groups. sixteen female ballet dancers participated in this study. They were divided into an expert group(age, $25.38{\pm}1.92$ years; height, $168.38{\pm}4.66$ cm; mass, $49.63{\pm}4.41$ kg) and a beginner group(age, $20.88{\pm}1.13$ years; height, $161.63{\pm}7.42$ cm; mass, $48.88{\pm}3.64$ kg) depending on their ballet experience. Descriptive data were expressed as mean ${\pm}$ standard deviation (SD) for all variables including the duration, displacement of the center of the body, velocity of the center of the body, angle of the body segments, angular velocity of the body segments, ground reaction force, lower extremity torque, muscle activity, body weight, age, and body mass. An independence t-test was conducted to determine how the following variables differed between the beginners and experts: duration, displacement of the center of the body, velocity of the center of the body, angle of the body segments, angular velocity of the body segments, ground reaction force, lower extremity torque, and muscle activity. All comparisons were made at the p<0.05 significance level. The results show that the experts scored high on the biomechanical variables, although all the variables were not significant. Significant differences were found in the angle of body segments, angular velocity of the body segments, lower extremity torque, and muscle activity(p<0.05). The findings of this study demonstrate that the experts have the required skill to make an improved Fouette turn. The findings may also help ballet dancers to learn and understand the Fouette turn.

In the present study, we investigated anti-inflammatory activity of artemisinic acid in HaCaT cells and RAW264.7 cells. Artemisinic acid showed inhibitory activity on macrophage-derived chemokines (MDC) expression, a factor related with atopic dermatitis (AD), in interferon (IFN)-${\gamma}$ and tumor necrosis factor (TNF)-${\alpha}$-stimulated HaCaT cells. In the study on action mechanism, pretreated artemisinic acid reduced the phosphorylation of STAT1 and p38 and the degradation of $I{\kappa}B$ by IFN-${\gamma}$ and TNF-${\alpha}$ stimulations. However, artemisinic acid didn't show the inhibitory activity on LPS-induced inflammatory mediators (NO, $PGE_2$, IL-6) in RAW264.7 cell. These results indicate that artemisinic acid inhibits IFN-${\gamma}$ and TNF-${\alpha}$-induced MDC expression through inhibition of signal factors, STAT1, NF-${\kappa}B$, and p38, in HaCaT keratinocytes.

Effective and systematic sanitation management programs are necessary to prevent foodborne disease outbreaks in school foodservice operations. The purpose of this study was to identify the elements to improve in order to ensure the safety of school food service by evaluating sanitation management practices implemented under HACCP-based programs. The survey was designed to assess the level of hygiene practices of school food service by using an inspection checklist of food hygiene and safety. Fifty-four school foodservice establishments considered as poor sanitation practice groups from two year inspections by Seoul Metropolitan Office of Education were surveyed from September to December in 2005. Inspection checklists consisted of seven categories with 50 checkpoints; facilities and equipment management, personal hygiene, ingredient control, process control, environmental sanitation management, HACCP system and safety management. Surveyed schools scored $68.0{\pm}12.42$ points out of 100 on average. The average score (% of compliance) of each field was 10.7/20 (53.3%) for facilities and equipment management, 7.4/11 (67.2%) for personal hygiene, 7.4/11 (74.1%) for ingredient control, 22.4/32 (69.8%) for process control, 8.9/12 (73.8%) for environmental sanitation management, 4.2/7 (59.7%) for HACCP systems management, and 7.2/8 (89.7%) for safety management, respectively. The field to be improved first was the sanitation control of facilities and equipment. The elements to improve this category were unprofessional consultation for kitchen layout, improper compartment of the kitchen area, lacks of pest control, inadequate water supply, poor ventilation system, and insufficient hand-washing facilities. To elevate the overall performance level of sanitation management, prerequisite programs prior to HACCP plan implementation should be stressed on the school officials, specifically principals, for the integration of the system.

The nangmyun is a Korean iced noodle made by putting buckwheat-noodles into cold broth. Seven samples of nangmyun-broths were collected from Korean restaurants in Bucheon during July 1994. The contamination levels of nangmyun-broths by coliform bacteria were determined, and then the 40 colonies of coliform bacteria, isolated randomly from 4 samples of nangmyun-broths, were identified at genus or species level with the additional test for psychrotrophic character The coliform counts in nangmyun-broths were 6.0x102-6.5$\times$104/ml(average 2.3$\times$104%). Among the 40 strains of isolates, 27 strains(67.5%) were identified as the genus Klebsiella, 9 strains(22.5%) as the genus Enterobacter, 2 strains(5.0%) as the genus Citrobacter and 2 strains (5.0%) as the genus Escherichia. Among 27 strains of Klebsiella, 11 strains (40.8%) were identified as K planticola, 4 strains(14.8%) as K. pneumoniae, 2 strains(7.4%) as K. ozaenae and 2 strains(7.4%) as K. terrigena, but 8 strains(29.6%) of a typic\ulcorner1 Klebgiella could not be Identified at species level. All the 40 strains of coliform bacteria were psychrotrophs showing slow growth at 1$0^{\circ}C$, and 18 strains(45%) grew at 5$^{\circ}C$. It was thought to be a good basic data In describing the reason for too high coliform counts in nangmyun-broths that all coliform bacteria tested In this study were psychrotrophs.

Objective : To evaluate the effect of Oriental Medical Treatment on a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation Method : We applied various methodology of Oriental Medical Treatment including Acupuncture, Electroacupuncture, Physical treatment, Herbal Medicine, Moxibustion treatment and Western medication as well. Result: Herbal medicine was applied on the basis of the patient's history. We applied formular to remove phelgm as a pathogenic factor after Hypoxic Ischemic Encephalopathy. At the same time, considering the patient spent more than a month in ICU lacking appropriate nutrition, we used formuli on the basis of 'Deficiency of Spleen' focusing to vitalize the function of digestive system. As the condition of the patient changed, we also adapted formular accordingly. We prescribed Herbal medication to strengthen Yin and Yang equally as she got hospitalized for long time. Also we applied Acupuncture treatment and Moxibustion treatment to control Qi flow. The general condition of the patient got better with successful removal of Foley catheter and elevated Glasgow Coma scale. We used Electroacupuncture, Physical treatment and Western medication at the same to get maximized effect on relaxing the contracted muscle. According to the Modified Ashworth Scale (MAS), we have some changes in muscle spasticity but later, the effect was not that significant. Conclusion : We had a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation. In the management of Hypoxic Ischemic Encephalopathy, Conservative treatments are the mainstream but there are not many alternatives. Therefore, We suggest that Oriental medical approach may contribute to the management of Hypoxic Ischemic Encephalopathy.

Objective : In this study we aimed to· investigate the parental recognition on Herbal Medication. The result showed that parents concerned about the effect of Herbal Medication on liver function and gaining weight. Therefore, we had a retrospective study on the effect of Herbal Medicaion on liver function and gaining weight. Method : In parent's recognition study, we surveyed 354 parents of children who make a first visit to Department of Oriental Pediatrics in ${\bigcirc}{\bigcirc}$ Medical Center from 3 October to 2 November 2005. In retrospective study, we examined medical record of 22 children who visited to Department of Oriental Pediatrics in Kyunghee Medical Center from 30 September 2005 to 1 January 2005. Height, weight, BMI, body fat mass, body fat ratio, AST and ALT were estimated at two points; before and after Herbal Medicaion treatment. Result: The mean of expectation of parents on the efficacy of Herbal Medication was 75.14 on the VAS scale, which was interpreted as significantly high. The result showed the effect of Herbal Medicaion on liver function(48%) and gaining weight(53%) took the largest portion. When we observe the effect of Herbal Medication on Liver function, after Herbal Medication treatment we have slightly increased AST and slightly decreased ALT, but they were not statistically significant. Also we observe the effect of Herbal Medication on getting obesity after Herbal Medication treatment. The result showed that we have slightly decreased BMI, body fat mass, body fat ratio, but they were not statistical1y significant. Conclusion : Our report shows parents of children have high expectation and stand favorable on the efficacy of the Herbal Medication. We found that parents concerned the most about the effect of Herbal Medicaion on liver function and gaining weight. Our retrospective study showed that Herbal Medicaion treatment on children has relationship with neither liver function nor the degree of obesity.
