The purpose of this study was to compare and analyze the behavior status of oral health between dental hygiene and non-dental hygiene students. The subjects in this study were students from two different colleges that were respectively located in Seoul and Gwangju. In order to examine the necessity of oral-health education, the self-recorded questionnaires had been widely distributed and surveyed from June 2006 to May 2007. The following results were obtained on the basis of comparative analysis through the collected materials. 1. As a result of surveying the actual condition of managing oral health, regarding the frequency of tooth brush, the dental hygiene students were the largest in 3 times. And, the non-dental hygiene students were indicated to be the largest in two times(p < 0.01). 2. As for the experience of scaling, the dental hygiene students were the most in having experience(50.9%), and the non-dental hygiene students were the most in having no experience(56.8%)(p < 0.001). 3. As a result of examining about the experience of oral-health education, the dental hygiene students were many in a case of having experience. And, the non-dental hygiene students were many in a case of having no experience(p < 0.001). The findings of the study showed that in terms of the state of oral health care, the dental hygiene students who received a lot of oral health education excelled the other students who didn't.

Recently, there has been a growing focus on the concerns pre-service teachers have as they move through different stages of their teacher preparation programs. Accordingly, the purpose of this study was to investigate pre-service secondary music teachers' concerns about music teaching and learning. The specific research questions were as follows: (a) What concerns are most common among participants? (b) What are differences in the concerns of pre-service secondary music teachers based on their stage of teacher preparation? (c) What are differences in the concerns of pre-service secondary music teachers based on their previous teaching experiences? A survey was distributed to pre-service secondary music teachers in a university in Seoul, and responses from a total of 93 participants were included in the final analysis. Data analysis indicated that pre-service music teachers experienced more concerns related to teaching tasks and student impact than themselves. Also, as participants progressed through their teacher preparation programs, self concerns decreased while task concerns and student impact concerns increased. Pre-service secondary music teachers who had previously taught in a school had fewer concerns than participants with no teaching experience. Suggestions for how teacher preparation programs can address the concerns of pre-service secondary music teachers are offered.

Recently the importance of emotional labor has increased so this study aims to prove the effects of emotional labor(surface acting and deep acting) on counterproductive work behaviors(deviate from organization and individual deviation) using burnout(emotional exhaustion, personality disorder, decrease in sense of accomplishment) as a medium. 350 surveys were sent to employees such as workers from call centers, salesperson from department store, financial worker, hospital staff, flight attendant and workers from customer center who and worked with emotional labor and 300 surveys excluding insincere ones were used for analysis. The result is as follows. First, surface acting which is a type of emotional labor chosen by customer workers had a positive effect on burnout such as personality disorder and decrease in sense of accomplishment. Second, deep acting had a negative effect on personality disorder and decrease in sense of accomplishment but did not show any effect on emotional exhaustion. Third, personality disorder and decrease in sense of accomplishment among burnout had effect on counterproductive work behaviors(deviate from organization, individual deviation) but emotional exhaustion did not show any effect on work behaviors(deviate from organization, individual deviation). Based on the result of analysis, implication of this study and direction of future research were suggested.

This study has been performed to evaluate the relationship between the remained mineral components in a decalcified bone matrix and an ectopic bone formation efficiency. The freezed rat diaphyseal cortical bones measuring 0.5cm in length were demineralized in heated 0.6N HCl at $60^{\circ}C$ for 5, 10, 15, 20, 25, 30, 35, 40 minutes, respectively, using a controlled heat ultrasonic cleaner. Each 1cc of decalcifying solution taken during decalcification procedure was used to calculate calcium content using calcium dignostics kit under 600nm of spectrophotomer. After decalcification, each specimen was also weighed. Then each prepared specimen was implanted into the dorsal pouch of 24 Sprague-Dawley rats divided into 8 groups by time course. The implants were harvested at 1, 2, and 3 weeks and prepared for routine H-E stain specimens to evaluate osteogenic activity. The results are as follows: 1. There was statistical significant difference in change of calcium concentration up to demineralization of 30 minutes and each allogenic bones decalcifed up to 20 minutes revealed 99.65% of decalcification in average. 2. There was statistical significant difference in change of weight in demineralized allogenic bone up to 20 minutes treatment but, no significant change was noted after that time. 3. The histologic analysis revealed active ectopic bone formation in the implanted allografts demineralized for 20, 25, 30 minutes, respectively. However, the other groups of allografts showed relatively poor osteoinductive activity. These findings suggest that complete decalcification with a minimized degeneration of collagen matrix is necessary to induce maximal osteogenesis by decalcified bone allograft.

Purpose: This study was conducted to compare nursing students' attitudes toward death, self-esteem and life satisfaction according to clinical experience. Methods: We surveyed 1,030 nursing students from two different universities with a questionnaire consisting of items regarding attitudes toward death, self-esteem and life satisfaction. The data were analyzed using a PASW program. Results: Students with clinical experience scored 2.85 on the attitude toward death, while those without clinical experience scored 2.79 (t=2.775, P=0.006). Students with clinical experience had significantly higher self-esteem (t=4.541, P<0.001) and life satisfaction (t=4.050, P<0.001) than those without it. Students with clinical experience showed correlations between attitude toward death and self-esteem (r=0.159, P<0.001) and life satisfaction (r=0.090, P=0.025), while those without it did not (r=0.106, P=0.014). Conclusion: These results provide guidance for developing educational strategies such as educational program to help students build positive attitude toward death through their experience in clinical practice.
