This study aimed to examine the effects of ego-resilience and social support on parenting stress perceived by mothers of school-aged children. The effects of demographic variables(including school grades of children) on the mothers' parenting stress were also investigated. The main results were as follows. First, ego-resilience of mothers was found to have the greatest predictive power on mothers' parenting stress. The more ego-resilient the mothers were, the less parenting stress was perceived. Second, social support also played an important role in alleviating maternal parenting stress. Emotional support of spouses was particularly effective in reducing mothers' parenting stress. Third, the only demographic variable that influenced mothers' parenting stress was their children's academic achievements. Finally, mothers perceived high parenting stress in relation to their children's school grades, while they perceived relatively less parenting stress concerning their children's temperament or the relationship with their children. The implications of these results were discussed.

The purpose of this study was to investigate the effect that completing long-term on-site training with varying grades of success had on the job satisfaction of former university students after obtaining employment. Although the grades themselves achieved during long-term on-site training did not directly affect job satisfaction, positive effects on job satisfaction were shown due to the mediating effects of job match and organizational commitment. The results of this study are as follows: First, it was found that employees who participated in long-term on-site training showed different results in belonging and attachment to their organizations according to their achievement. The higher the grades during long-term on-site training, the higher the degree of reported job match and organizational commitment, suggesting a positive correlation with job satisfaction. Therefore, long-term on-site training should not be operated as simply a program for temporary experiential learning, but instead should be optimized by companies and schools to motivate their students to achieve high grades for the purpose of their future job satisfaction.

Many attention have been paid to the innovative technologies aiming at the paradigm shift such as the modular housing, pre-fabrication method, or long-life housing. Despite the government's efforts to diffuse the long-life housing, few case gained the high grades by applying various technologies required in the Long-life Housing Certification System. The concerns of cost increase and low profit are the main reason why most of the construction firms avoid the adoption of long-life housing. In this study, the variations of construction costs were analyzed according to the grades in the Long-life Housing Certification System. The results of this study will help the decision makers find the optimal solution in employing the long-life housing technologies during planning.

This study was done to develop self - directed learning modules related to asepsis and elimination including urine and stool for Fundamentals in Nursing practice education contents and to measure the effectiveness of those modules. The subjects of this study were 96 sophomore students in the nursing college. Self-directed learning modules were developed by the researcher on the basis of the Lippincott Learning System of Kruger (1986) and Modules for Basic Nursing Care of Ellis (1992). Videotape was editted by using videotape made by the Lippincott Company and Film strip made by the Trainex Company with Korean dubbing. Self-directed learning was done for one week with the asepsis module and two weeks with the elimination modules after confirming the requiered level of knowledge acquisition through pre-test. For measuring proficiency in self-directed learning, a written test for cognitive domain, a sufficiency test for psychomotor domain, and a confidnece examination for affective domain were given. The data were analyzed using descritive statistics, and Pearson correlation coefficient using a SPSS-PC program. The results are summarized as follows: 1. Sufficiency test and confidence examination grades showed high levels in both asepsis and elimination. 2. Written test grades showed a high level in asepsis and elimination of urine but showed a medium level in eliminationin of stool. 3. Grades of sufficiency and confidence in asepsis and elimination practice were statistically significant with a moderate positive correlation (r=0.4- 0.5, p<0.001). 4. Grades of sufficiency and written tests in asepsis and elimination practice also were statistically significant with a moderate positive correlation (r=0.5-0.7, p<0.001). 5. Students showed relatively high contentment with the self-directed learning modules themselves but revealed relatively low contentment with video program and the self-directed learning process. In conclusion, this study disclosed that proficiency levels in cognitive, affective, and psychomotor domains were high when asepsis and elimination modules were applied. Also students showed high satisfaction with the modules themselves, but didn't show high contentment with the video programs. In considering low contentment with the self-directed learning process, it is estimated the students had experienced some difficulties about using self-directed learning modules because this was their first exposure to the self-directed learning module and they were already accustomed to the demonstration-practice method.

Dyeability of Indian natural dyestuffs to fabrics was investigated. Indian dyestuffs are more inexpensive than domestic dyestuffs purchased at oriental medicine stores. We studied the dyeability of madder, marigold, and pomegranate imported from India on cotton, silk, and wool fabrics. Dyebaths of a combination ratio of 80:20, 60:40, 50:50, 40:60 and 20:80 of madder and marigold, fabrics with orange colors were dyed. To evaluate the dyeability of dyed fabrics, K/S values, Munsell color values and CIE L, a, b, ${\Delta}E$ were measured. The dyeability of fabrics dyed in dyebaths of pH 4 and pH 7 were higher than pH 10. The dyeability in pH 4 was better than pH 7. Silk fabrics dyed with madder and marigold showed good dyeability and wool fabrics showed good affinity in madder dyebath and fair affinity in marigold dyebath. Cotton fabrics showed fair affinity in a marigold dyebath of pH 4 and pH 7. Cotton fabrics dyed with a 60:40 ratio of madder and marigold showed 4.76YR of Munsell color value. Silk Fabrics dyed with a 40:60 ratio showed 4.76YR and wool fabrics dyed with 20:80 ratio showed 5.57RY. The ratios produced the closest colors to 5.0YR of orange. This result indicated that marigold had a more powerful effect on cotton fabrics while madder was stronger on wool fabrics. Fading grades of washing colorfastness of wool and silk fabrics dyed in mixed dyebaths were higher than 3.5-4.0 and higher than homogeneous dyebaths. Staining grades of washing colorfastness of all dyed fabrics were between grades 3.5-5.0. Colorfastness to dry-cleaning was high as grades 4.0-5.0 in all of dyed fabrics. Colorfastness to light of dyed fabrics showed a fair grade of 3.5-5.0; in addition, wool fabrics showed lower grades than silk and cotton fabrics.

The densification behavior during a sintering of M2 and T15 grade high speed steel powder compacts was reported. Sintered densities over 98% theoretical were achieved by a liquid phase sintering in vacuum for both grades. The optimum sintering temperature range where full densification could be achieved without excessive carbide coarsening and incipient melting was much narrower in M2 than in T15 grade. The sintering response was mainly affected by the type of carbides present. The primary carbides in M2 were identified as $M_6C$ type whereas those in T15 were MC type which provides wider sintering range. The addition of elemental carbon up to 0.3% lowered the optimum sintering temperature for both grades, but had little effect on expanding the sintering range and sintered structure.
