Purpose: The aim of this research was to investigate difference in shear bond strengths of full-contour zirconia layered with porcelain. Methods: Disk-shaped (diameter: 12.0 mm; height: 3.0 mm) zirconia were randomly divided into six groups according to the surface conditioning method to be applied (N=90, n=15 per group): group 1-contol group(ZC); group 2-airborne particle abrasion with $50-{\mu}m\;Al_2O_3(5A)$; group $3-50-{\mu}m\;Al_2O_3$ + liner(5AL), group $4-110-{\mu}m\;Al_2O_3(1A)$; group $5-110-{\mu}m\;Al_2O_3$ + liner(1AL); group 6-liner(LC). On each block, zirconia porcelain was build up according to manufacturer's instructions. All samples were fixed with measuring jigs and shear bond strength were measured with Universal testing machine. Collected data were analyzed using SPSS(Statistical Package for Social Sciences) Win 12.0 statistics program. Results: LC showed the highest value($29.92{\pm}2.55$ MPa) and ZC showed the lowest value($13.22{\pm}1.37$ MPa). Zirconia liner and Alumina oxide groups was significantly higher shear bond strength than control(p<0.05). 5A (without liner $22.18{\pm}2.37$, with liner $22.84{\pm}1.74$ MPa) was higher shear bond strength than $110{\mu}m$ (without liner $20.18{\pm}2.38$, with $20.71{\pm}2.67$). Conclusion: Surface treatments may have advantage in bond strength improvement for full-contour zirconia layered with porcelain.

The purpose of this study was to identify the effect of individual emotional characteristics (empathetic concern and emotional contagion) on emotional labor (frequency of emotional display, intensity and variety of emotional display, surface acting, and deep acting) of school dietitians. Data was collected through a questionnaire survey of 309 school dietitians and then analyzed statistically by SPSS 18.0 package program. The results of this study were as follows: empathetic concern (3.93) occurred more often than emotional contagion (3.22) in school dietitians. The older (p < 0.001) and more experienced (p < 0.01) they were, the higher empathetic concern they had. It showed that married dieticians (p < 0.001), nutrition teachers (p < 0.01), and dieticians who were working in elementary schools (p < 0.01) had a higher rate of empathetic concern than single dieticians, non-nutrition teachers, and dieticians who were working in middle and high schools, respectively. Their level of emotional labor was the highest in deep acting (3.32), followed by surface acting (3.28), frequency (3.12), intensity and variety (3.09). According to multiple regression analysis, emotional contagion proved to be strongly significant and positively related to frequency of emotional display (${\beta}=0.257$, p < 0.001). Both empathetic concern (${\beta}=0.117$, p < 0.05) and emotional contagion (${\beta}=0.162$, p < 0.01) were positively related to intensity and variety of emotional display, and empathetic concern (${\beta}=0.173$, p < 0.01) had also an effect on deep acting. These results suggested that the emotional labor of school dietitians should be managed on the organizational viewpoint, not a personal matter.

The data were analyzed by SPSS(Statistical Package for Social Science), utilizing PC. The statistical significance was tested at 0.05 level. The major findings of the study were as follows : 1. The job satisfaction measuring instrument, the researcher developed, could measured the job satisfaction of dental technicians. The Maximum score of the instrument was 125, the highest score of dental technicians was 106, the lowest score was obtained 38, the mean score was 72.228 and standard deviation was 12.804. 2. The personal variables of dental technicians were related with the job satisfaction scores. The job satisfaction scores were positively correlated, at 0.01 level, with the scores of age(r=0.379), year(r=0.218), aptitude(r=0.415), marry(r=0.202), income(r=0.381), career(r=0.316). 3. The family variables scores of dental technicians were not correlated with the job satisfaction scores. 4. The personal characteristics of dental technicians were related with the job satisfaction. The job satisfaction score were positively correlated beyond the significant level, with the cheerfulness scores(r=0.398) and stability scores(r=0.224). 5. The job-related variables of the dental technicians were related with the job satisfaction scores. The correlation coefficient between job satisfaction scores and turnover scores was r=0.23, and quantity scores was r=0.300.

Objective : This study came to be carried out in order to develop oral health education program for maintaining adolescents' oral health and to be helpful for qualitative improvement in prevention program by surveying the awareness and behavior on preventive method of dental caries in adolescents. Method : The collected materials of totally 1,100 people who responded were carried out frequency analysis by using SPSS 12.0(Statistical Package for the Social Science). Results : 1. As for the results of awareness on fluoride effect and sealant effect, the students with response to 'effect of preventing decayed tooth' were indicated to be the highest. It was indicated to be the highest in girls as for gender and in the 2nd grade as for school year. (p<0.05). 2. As for the results of being created when eating sweet food and carbonated drink, the students with response as saying that 'a decayed tooth occurs well' were indicated to be the highest. 4. As for the results on the aim of visiting dental clinic, the students with response as saying of 'visiting for having treatment' when tooth is painful were indicated to be the highest. Conclusion : Synthesizing this study, the students' awareness on preventive method of dental caries was high. But the practice on regular check-up or diet was indicated to be low. Through oral health education, the adolescents should be not only delivered information or knowledge, but also changed habit and behavior.

This nutritional survey was conducted in February 25, 1999, in order to investigate the nutritional knowledge, dietary attitudes and nutrient intakes of dietitians living in Kangwon area. Subjects consisted of 250 dietitians, with 184 in school food service, 14 in hospital food service and 52 in institution food service. Data were analyzed for frequencies, means, t-test, $x^2$-test, ANOVA and Pearson correlation using SPSS PC Package. The results obtained are summarized as follows: The average nutritional knowledge score was 10.15 out of possible 15 points, and dietary attitude score was 67.93 out of 100 points. The correlation between nutritional knowledge score and dietary attitude score was lowly(${\gamma}=-0.25$). Nutrients consumed below the Korean RDA were energy (78.77%), Ca(90.5%), Fe(83.70%) and nutrients consumed above the Korean RDA were protein(110.83%), P(140.21%), vit.A(163.94%), $vit.B_2$(126.37%), niacin(121.12%) and vit C(231.86%). Carbohydrate, protein and fat ratio on energy composition was 63%:17%:20%. The nutrient density among 3 groups of dietitian was not significantly different.

The purpose of this study is to segment the mobile phone users based on the flow types and to understand the differences in mobile phone usage behavior between the segmented groups. The 'flow' construct, which was introduced first in marketing by Hoffman and Novak[44], has been used as an important keyword for understanding consumer behavior on the World Wide Web. In this paper, we will try to use the flow aspect for the mobile market segmentation, which is one of the most fundamental tools for developing a successful marketing strategy on the mobile phone service market. We collected survey data from consumers and analyzed the data with the SPSS 12.0 package where we did ${\chi}^2$-test, factor analysis, one-way ANOVA and cluster analysis. Main results of this study are as follow. First, the flow types of the mobile phone users were classified into five types, which are named as the 'Flow' type, 'Apathy' type, 'Anxiety' type, 'Boredom' type, 'Control' type. Second, most of the results related to the usage of mobile phone service showed statistically significant differences between flow types. These findings suggest that the mobile phone service marketers should consider the various flow types of users and work out effective market segmentation strategies based on these consumer flow types.
