This study examined pruritus to provide the data based on burn patient pruritus. A self-report questionnaire survey was conducted among ninety five burn survivors, who were over 18 years of age with admission periods longer than two weeks. The results indicated that the average burn range was $18.95{\pm}17.10%$, severity was $48.83{\pm}23.96$, and distress was $46.42{\pm}25.80$. A significant difference in pruritus consequences was observed according to frequency. The patients consistently experienced pruritus, even if it happened less often, difficulty in falling asleep (F=4.817, p=.004), poor mood (F= 5.955, p=.015)), and loss of concentration (F=6.483, p<.000). A significant difference in the pruritus consequences according to duration was observed, lasting for 30 minutes for all groups, more than the population and less than 30 minutes, difficulty in falling asleep (F=7.452, p<.000), poor mood (F=3.655, p<.015), and loss of concentration (F=12.564, p<.000). The frequency, duration (r=.29, p=.004), severity (r=.45, p<.000), distress (r=.44, p<.000), and consequences of pruritus in burn patients (r=.29, p=.004) showed a positive correlation. The results of this study could be used as a base material for the care of burn patients experiencing pruritus.

Pseudomanas fluorescens was selected from mushroom and studied in both batch and continuous culture in order to find out optimum conditions for cultivation. P. fluorescens is an aerobic bacterium and antagonistic to Pseudomonas tolaasii which causes blotch disease on the mushroom cap. Cells of P. fluorescens were grown well on medium containing 30g/L of glucose, whereas the growth was inhibited with the glucose concentration at higher than 30g/L. The highest value of specific growth rate and productivity were obtained when using 10g/L of yeast extract. Optimum concentrations of $NH_4Cl$ and $(NH_4)_2SO_4$ for culture were found to be 1.0g/L and 0.1g/L respectively. Optimum concentration of $MgSO_4{\cdot}7H_2O$ used as a sulfur source was 1.0g/L. It was also found that the cell concentrations were at the maximum level when grown on the medium containing 1.0g/L of $KH_2PO_4$ and 0.1g/L of $CaCl_2$. Also, the optimum culture conditions were $30^{\circ}C$ and pH 6.0. Cultivation of P.fluorescens at high initial dissolved oxygen (D.O) value led to a decrease of bacterial productivity in batch culture. Maximum productivity was achieved at 68 for the initial D.O value.

Gluten proteins are key to developing a unique quality of flour because they confer viscosity, cohesiveness, and elasticity in the dough. However, gluten can impede digestion and absorption in gluten-sensitive individuals. In this study, enteritis was induced in mice with dextran sulfate sodium (DSS) salt. The mice later received a diet consisting of 3%, 12%, or 30% fermented noodles with degraded gluten (FNDG) or 30% normal noodle flour for 8 weeks. FNDG did not alter the growth performance or body composition. However, FNDG resulted in increased amylase activity in a dose-dependent manner (p<0.001), and it also improved the digestive capacity. FNDG at 30% concentration increased the level of gastrin (p<0.01) implying increased gut motility. The serotonin receptor levels were significantly reduced by FNDG at 12% (p<0.05) and 30% (p<0.01) concentrations. These findings indicate that a diet containing FNDG could help in the recovery from intestinal inflammation with improving digestive ability and gut motility. Overall, the inclusion of degraded gluten in the diet was found to enhance digestion, gut motility, and absorption in mice.

Objectives: The salivary gland tumor shows heterogeneity in histologic patterns and biological behavior. The aim of this study is to elucidate the relationships between apoptosis and expressions of apoptosis-related factors(bcl-2, bax, M30), p53 and MIB-1 in the salivary gland tumors. Methods: Immunohistochemical stains for apoptosis-related factors, p53 and MIB-1 and TUNEL study for apoptosis were performed in 46 cases of salivary gland tumors 02 benign and 34 malignant). Results: Twenty(43.5%) of 46 cases showed positive reaction for apoptosis, and the expression rates of bcl-2, bax, M30, p53 and MIB-1 were 85.3%, 68.8%, 65.9%, 39.1% and 26.1%, respectively. A significant difference between benign and malignant tumors was only noted in MIB-1 expression(p=0.0167). In malignant tumors, apoptosis showed no significant relationships to expressions of apoptosis-related factors. There were inverse relationships between p53 and bcl-2 expression(p=0.0375), and between M30 and MIB-1 expressions(p=0.0379). No significant differences of apoptosis, bcl-2, bax, M30, p53 and MIB-1 expression rates according to the tumor size, lymph node status, recurrence and survival were found. Conclusion: In the development of benign and malignant salivary gland tumors, apoptosis might be associated, however, apoptosis and expressions of apoptosis-related factors seemed to be not reliable prognostic factors in malignant salivary gland tumors.

The present study concerns the acid neutralization capacity (ANC) of cement paste, mortar and concrete depending on a free water-cement ratio. The ANC of paste at 30%, 40% and 50% of water-cement ratio was measured and simultaneously the effect of aggregate on the ANC was evaluated. It was found that an increase in the acid concentration resulted in a decrease in the pH of the suspension, in particular, at 10 in the pH, a sharp decrease was observed. The ANC showed some peak resistances to acid at particular pH values.

Effects of sulfur application on mulberry growth and soil chemical properties were examined in mulberry trees grown in a green house. Mulberry graftages were planted in Wagner pots and sulfur was applied at the levels of 0, 30, 60, or 120 kg/10a. Mulberry stem growth increased by 3.2 cm at 30 kg/ha than at 0 kg/ha sulfur application. Stem growth, however, decreased by 3.7 cm with the application of sulfur higher than at 60 kg/10a. Soil pH changed by the application of sulfur. With the application of sulfur at 120 kg/10a, soil pH decreased by 3.0. Temporal changes in the effective from sulfur content in soil indicated that sulfur dissolved between 4 to 10 days after application in the soil. Content of moisture and chemical components in mulberry leaves was also affected by the application levels of sulfur. Moisture, total-N, No3-N, K, and S content decreased, but F and Ca content increased with the application of sulfur lower than at 60 kg/10a. With the application of sulfur higher than at 60 kg/10a, P, S, and K content increased.

The purpose of this study was to analyze the dietary habits and food intake by age, based on the nutrition counseling data of medical health examination. The subjects were 5,511 adults(3,139 males and 2,372 females) who took comprehensive medical test in Gyeonggi area, and they were evaluated from January 1, 2007 to December 31, 2007. Survey samples were divided by age groups : 30>, 30~39, 40~49, 50~59, 60~69, 70{$\leq}$ years. The subjects were composed of 57% male and 43% female. The results showed that the dietary habits of ${\geq}$50 group were relatively good. On the other hand, in 30> yrs group had more dietary habit problems, they had irregular meals and the ratio of skipping breakfast was high. And they frequently had meals out. regularity of meals, eating breakfast was higher in ${\geq}$70 yrs groups than in other groups(p<0.001). frequency of overeating was higher in 30>, 30~39${\geq}$yrs groups than in other groups(p<0.001) and speed of eating meal were fast in 50~59 yrs groups than in other groups(p<0.01). For foods with high cholesterol and fat, it was shown that the older the subject, the fewer the frequency of consumption(p<0.001). For kimchi and salty foods, food intake showed a negative relationship with age(p<0.001), whereas for fresh vegetables and high-calcium fish, it showed a positive relationship(p<0.001). All in all, it was shown that as the people get older, their dietary habits tend to get more appropriate. In conclusion nutrition education based on their dietary habit by age should be taught, so that people have a healthy dietary habit and food intake for the rest of their life.

High-rate phosphorous removal by PAC (poly aluminum chloride) coagulation of A2O effluent was investigate to meet the stringent requirement of wastewater discharge from municipal wastewater treatment plant. A series of jar tests were conducted to find optimum coagulation condition and to enhance removal efficiency. The optimum volumetric concentration of PAC was 30 ppm (2.81mol Al/mol P by mol ratio). Only 17.2% of soluble P was removed for 30 minutes' settling without PAC addition, while this increased to 30.3% by dosing 10ppm PAC. It even increased conspicuously from 49.3% to 88.4% by increasing PAC dose from 20 ppm to 30 ppm. 92.4% of total P was removed by 30 ppm PAC, and the effluent concentration (0.3 mg/L) was acceptable for discharge. The optimum value of coagulation time, settling time, and pH were 4minutes, 20 minutes, and 7.0, respectively. It was not necessary to control pH of raw sample whose pH was 7.0. Soluble P removal was remarkably enhanced at pH 7.0. This implied that sweep floc formation by $Al(OH)_3$ was the main mechanism of coagulation for soluble P removal. Influent and effluent of secondary clarifier were tested for coagulation, and the effluent was better for high-rate P removal. It resulted in 0.18 mg/L of P and 95.4% of P removal by coagulation. It was favorable to recycle the treated water to coagulation tank and the optimum recycle ratio was 0.3.
