Currently, as mordants, heavy metals are being used in dyeing process in order to improve dye uptake and dye fastness. These chemicals, however, are mostly harmful to human body and the environment along with the pollution by effluent. Traditionally, rice straw ash solution, lime, etc. have been used as mordants in order to improve the effects on dye uptake and color fastness of dyestuffs. The study of natural mordants would, therefore, be vital to the development and succession of our traditional dyeing methods. In this study, as a preliminary step toward the use of rice straw ash solution for the nautral dyeing using Caesalpinia sappan, several aluminum compounds were employed as mordants. When the purified aluminum compounds were used, on the basis of unmordanted cotton fabric, the WS values of the pre-mordanted and simultaneously mordanted fabrics increased by 2 or 3 times, while those of the post-mordanted fabrics decreased.

Objectives : This study was conducted to develop the Korean version of the I0WA Conners rating scale (K-IOWA), and to examine its reliability and validity. Methods : The subjects were 41 normal children and 40 ADHD children between the ages of 5 and 12. All of the teachers administered the K-IOWA and the abbreviated Conners' rating scale to calculate the internal consistency coefficient of the K-I0WA and to examine its validity. Results : The reliability coefficient of the K-IOWA (Cronbach's α) was .913. The range of correlation coefficients between K-IOWA scores and the Abbreviated Conners Rating Scale scores were from .81 to .93. The mean score of the ADHD group on the K-IOWA was significantly higher than that of the normal group. The result of factor analysis showed that the K-IOWA was composed of 2 factors (Inattention/Overactive and Oppositional/Defiant). Conclusion : These results suggest that the K-IOWA rating scale is a very reliable and valid test and it would be useful in diagnostic evaluation and the treatment effect for ADHD children.

Objectives: The purpose of this study was to identify the influence of equality perception and organizational commitment on turnover intention of jobs among psychiatric hospital nurses. Method: Data were collected by questionnaire survey among 158 nurses working in 10 psychiatric hospitals from August 1st to September 30th. 2004. Results: The degree of turnover intention of jobs was significantly different by marital status, religion, qualification of psychiatric specialized nursing, monthly income and the location of hospitals. The correlation analysis showed that the turnover intention of jobs decreased as the equality perception and the organizational commitment increased. The hierachical multiple regression analysis showed that significantly related variables with turnover intention of jobs were religion, monthly income, equality perception and organizational commitment. The model explanation power was 53.1%. Conclusion: Because the equality perception explained 53.1% of variance of turnover intention among psychiatric nurses and organizational commitment was related with the turnover intention of nurses at psychiatric hospitals, activation strategy of organization must include the promotion strategy of equality perception and organizational commitment to decrease turnover intention of jobs among nurses.

Objective: The Lispro insulin has faster onset of effects and shorter duration than the human regular insulin, an analog of human insulin. The differences in the pharmacodynamics between the two types of insulin in the continuous subcutaneous insulin infusion(CSII) with insulin pump for treating the Korean Type 2 DM patients were analyzed. The effects on the regulation of blood sugar, the amount of insulin injected, and the frequency of hypoglycemia were compared between the lispro insulin and the regular human insulin. Method and Material: One hundred and three Korean Type 2 DM patients were randomly divided into two groups, 49 Lispro insulin and 54 Regular insulin.(Table 1) Both groups were treated for 14 days. Also at a set time before meal, insulin was injected as bolus, using a portable insulin pump, in both groups, 15 minutes before for lispro insulin and 30 minutes before for human insulin The HbA1C, C-peptide, AC/PC, height and weight were measured for each patients at the time of admission. The peripheral blood sugar level and insulin injection profile were recorded 7 times per day for each patients. Results: After treating for 7 days and 14 days, the blood sugar level normalized in both groups. There weren't any significant differences in blood sugar levels in both groups at point of the study, and also there weren't any differences in the frequency of hypoglycemia. In order to maintain the normalized blood sugar level, the lispro insulin group had higher total daily insulin requirement than the regular insulin group after 14 days of treatment (0.90±0.35 vs 0.73±0.39u/kg/day, p<0.05) This difference is probably due to the difference in basement insulin requirements rather than prandial insulin requirements (0.32±0.1 vs 0.43± 0.09u/kg/day, p<0.001). Discussion: In the hospitalized Korean Type 2 DM patients with CSII treatment, continuous subcutaneous insulin infusion therapy using lispro insulin has convenience in usage compared to the regular insulin. However, there were not any differences in the blood sugar levels. Also lispro insulin requires more insulin in order to maintain normal blood sugar level, which is probably due to the increase in the basal requirement. Also there were not any difference in the frequency of hypoglycemia.

In this study, the shear bond strengths and accompanying elastic modulus ratio, displacement at bond failure and work up to fracture of pit and fissure sealants to toothe enamel were analyzed by the following variables, those were acid etching, moisture content of the surface of enamel, dentin bonding agent(species and method), thermocycling, saliva contamination. One kind of chemically cured resin based pit and fissure sealant, two kinds of light cured resin based pit and fissure sealants and one kind of glass ionomer based pit and fissure sealant, and two kinds of dentin bonding agents were studied. The buccal surface of extracted premolars were ground flat with # 600 silicone carbide papers, and the ground surface was treated depending on the experimental conditions. After each treatment, each pit and fissure sealant was filled into plastic tube of 3mm diameter, which were laid on the surface of ground enamel surface, and were cured. Sealant bonded teeth specimens were immersed in 37℃ distilled water form 24 hours. The shear bond strength of sealant to enamel surface was measured with Universal testing machine with the cross head speed of 1mm/min. From the obtained load-deflection curves, modulus ratio, bond strength, displacement at bond failure and work up to fracture were analyzed. From this experiment, the following results were obtained : 1. Comparing the results of standard condition(i. e. acid etching, dry surface, no dentin bonding agent and 300 thermocyling), the elastic modulus ratio of chemically cured resinbased pit and fissure sealant was significantly higher than those of other materials(P<0.05), and the bond strength, displacement at bond failure and work up to fracture of glass ionomer based pit and fissure sealant were significantly lower than those of other materials(P<0.05). 2. The results of ANOVA with the variables of type of material, acid etching, moisture condition of the enamel surface, dentin bonding agents were as follows ; 1) variables showed significant main effect on the shear bond strength of pit and fissure sealant to enamel(P<0.01), 2) type of material, acid etching and moisture condition of enamel influenced the bond strength significantly(P<0.01), 3) type and application methods of dentin bonding agents influenced on the bond strength significantly(P<0.05). 3. There were statistically significant correlation between the work up to fracture and the bond strength, and between the work up to fracture and the displacement at bond failure(P<0.01), and in these cases the correlation coefficient was 0.87.
