Objectives : This research was conducted to find the subjective symptoms of musculoskeletal system for main jobs and job posture. Methods : A survey was conducted from September 15, 2011 to October 7, 2011 and 357 dental hygienists were responded. The survey was consisted of the working environment and medical equipments, psycho-social characteristics, health habits and education, job posture, subjective symptoms of musculoskeletal system pain, and so on. Results : In the survey on the frequency of job posture of dental hygienists by jobs, said they cast down or tilt their head by 15 degrees or more or twist or bend their back. The result of the analysis on the subjective symptoms of musculoskeletal system by main job showed that they experienced a pain in neck, shoulder, and back, although the order differed. The order of subjective symptoms of musculoskeletal system for casting down or turning head by 15 degrees or more, twisting or bending back, having shoulders not parallel to the ground, sitting at the end of a chair, and supporting the whole body with one leg or pressing on a pedal for treatment was from the shoulders to the neck to the back. The order of subjective symptoms of musculoskeletal system for having arms too far from the body or hunching for treatment and bending wrists inward or outward for treatment was from the shoulders to the back to the neck. Conclusions : Due to the characteristics of the job which requires one to have a proper view of a patient's oral cavity, most of the postures included casting down of head or bending of back. Therefore a development of new postures is needed to replace the existing job postures which pressure the musculoskeletal system. And shift rotation can be used as a preventive measure.

Objectives : The purpose of this study was to investigate of the color change, tooth surface and intra-pulpal temperature of tooth bleaching by light activation Methods : Forty-eight extracted bovine teeth were immersed into a tea solution for 24 hours. The specimens were randomly divided into four groups(n=15):(G1) 15% HP + without light activation, (G2) 15% HP + light activation, (G3) 25% HP + without light activation, (G4) 25% HP + light activation. All specimens were bleached for 15 minutes three times. The spectrophotometer (CM-2600d, Konica Minolta, Osaka, Japan) was used including before bleaching, immediately after bleaching, 1 week, 1 and 3 months after the end of bleaching. The temperature rise were measured in the pulpal chamber and tooth surface with a digital thermocouple thermometer(Termopar Digital Multimeter, Tektronix DMM916, USA). Between the tested time points, the specimens were stored in distilled water. The data were analyzed by ANOVA, t-test and Tukey's post hoc test set at 0.05. Results : There was no significant color change by the use of light after the bleaching treatment(p>0.05). The dental bleaching treatments of teeth with 15% HP and 25% HP did not seem to be more effective when light source was used. There was no difference in color stability between groups within three month(p>0.05). There was an increase in tooth surface and pulp temperature, but it was not sufficient to cause damage to the pulp. Conclusions :The use of light activation has no obvious effective impact on the tooth bleaching effect.

This study aims at examining the effect of strategic orientation on IT startup performance and analyzing the mediating effect of network in the relationship. The study was conducted on the three dimensions that make up strategic orientation: technological orientation, customer orientation, competitive orientation on firm performance, and the understanding of the role of the network. Empirical research on 94 IT startups as residents of startup support institutions was conducted. The suitability of the research model was evaluated with PLS-SEM. As a result of the empirical analysis, customer orientation and competitive orientation was verified to have a positive effect on network, while Technological orientation was confirmed to have no positive effect. and network mediated the relationship between customer orientation and competitive orientation, while Technological orientation was confirmed to have no positive effect. The results of this study provide startup practitioners with strategic direction and the importance of network establishment and utilization.

Except incomplete answers, 200 data were analyzed. The questionnaire consisted of 10 questions of preparation for old age and awareness for old ages, 9 questions of physical preparation, and 9 questions of emotional preparation. Cronbach's alpha of old age preparation and awareness of old age was 0.634 in the study. Cronbach's alpha was 0.709 and 0.757 in physical preparation and emotional preparation, respectively. The final analyses of 200 copies were conducted using SPSS 11.5 software for Windows(SPSS Inc., Chicago, lllinois, USA). Results: Awareness toward preparation for old age of dental hygienists was 3.72 points, physical preparation was 2.94 points, and emotional preparation was 2.91 points. Awareness toward preparation for old age of dental hygienists showed the relationship between birth date, marital status, education level, and subjective health condition. Physical preparation was closely related to birth date, marital status, education level, and the workplace.

Purpose: The purpose of this study was to investigate the effect of oral health education on adolescents. Methods: The subjects were middle school students in a health promoting school in Gunpo, Gyeonggi Province. Before giving the students oral health instruction, their modified Patient Hygiene Performance index (PHP index) was measured using disclosing solution. Then, the students were taught the right way to brush teeth (Rolling method) and use oral hygiene devices such as dental floss, tongue cleaner and interdental brush. Their modified PHP index was re-measured three days after and seven days after the education to evaluate the effect and persistency of oral health education. of the total 116 students, 48 students who completely filled out the questionnaire and participated in the whole process, photo shooting and three times of PHP index measurement, were included in the final analysis. Results: The students' modified PHP index significantly decreased three days after the education. However, the index slightly went back up seven days after the oral health education. Conclusion: Oral health education was effective in reducing dental plaque which remained after brushing. Continuous education about and constant motivation for oral hygiene turned out to be critical to maintain the impact of oral health education. Therefore, it is necessary to develop educational contents which can constantly motivate teenagers.
