Objective: In order to utilize dietary control, one of ways to prevent dental caries, more easily, the sugar content and viscosity of food were measured to obtain cariogenic index. Using this index, this study is to contribute to having proper eating habits through improvement of eating habits and to the prevention of dental caries through the use of computation program for dietary control. Methods: A 5-day dietary log from 105 students in the first year of high school, who are residing in Cheonan, and the result of survey was entered into the existing computation program for dietary control to examine calorie intake, 3 major nutrients and deficiency of clean food intake count, cariogenic index; S-PHP index and Snyder test were performed to examine the correlation of each category with oral health. Results: The ratio of average daily intake of 3 major nutrients was 62.4:19.9:17.7 respectively, and the average daily intake count of clean food was 2.44±1.71, which was appropriate. The average cariogenic index, 152.89±65.45 min. Since cariogenic index (r=−0.535), S-PHP index (r=−0.338) and Snyder test (r=−0.365) decreased as clean food intake count increased, they showed a relatively high correlation (p<0.01). Conclusion: Computation program for dietary control enables analyzing adolescents’ dietary habits by category and leads them to have proper eating habits through improvements in eating habits, which will result in dental caries prevention and oral health improvements; therefore, utilization of the program for preventive care in clinical environment is recommended.

The purpose of this study was to investigate the influence of the degree of consciousness and satisfaction of body cathexis on the preference of various colors. A survey was conducted using the randomly selected 439women in the twenties. The consciousness variable had three levels which are lean, medium, and obese shape for each whole, upper and lower body with self-consciousness. Also, satisfaction variable had three levels which were satisfying, average, and unsatisfying group. The data were analyzed using analysis of correlation, crosstabulation analysis, and analysis of variance test. The results were as follows '. 1) There was the positive correlation between height, leg length, and arm length, and each variable, and the negative correlation between back width, hip girth, thigh girth, waist, lower leg girth, ankle girth, and upperarm girth, and each variable. Also. we could observe the tendency that the larger the head or the more the weight was. the lower the satisfaction of body was. 2) There were no strong correlation between bust size and hand size and each variable. From the crossed classification, we could observe the tendency that the smaller the bust was, the lower the satisfaction of body was. 3) There were the strong correlation between whole and upper body in consciousness degree and between whole and lower body in satisfaction. 4) The consciousness of the whole body was shown lean shape 23.4%.medium shape 49.2%, and obese shape 27.2%. For the satisfaction degree of the whole body, satisfaction was shown 6.8%, average 41.7%and unsatisfaction 51.4%, so the satisfaction group is very small. 5) From the analysis for the consciousness degree of the whole body, there was the statistical significance in yellow, blue, purple. 6) From the analysis for the satisfaction degree of the whole body, there was the statistical significance in red. blue. purple, gray. chain

Objectives: This study presents job embeddedness as the principal factor that reduces turnover intention of clinical dental hygienists. The study also promotes the utilization of job embeddedness for efficient human management in dental organizations. Methods: A self-reported questionnaire was completed by 200 dental hygienists from June 1 to July 15, 2019. Data were analyzed using SPSS 20.0. An independent t-test, a one-way ANOVA, Scheffe post-hoc test, and Pearson’s correlation coefficients were employed, and a multiple regression analysis was conducted. Results: The dental hygienists scored 3.25 points for job embeddedness, 3.81 points for organizational citizenship behavior, and 3.40 points for turnover intention. The variables that influenced their turnover intention were those related to job embeddedness. These factors showed 24.6% variance among the dental hygienists. Conclusions: Efficient human management of clinical dental hygienists requires increased interaction and compatibility within dental organizations. It is also necessary to create a variety of benefits and support systems.

Developing of high technology, productivity of the fiber product has being rapidly increased and also various kinds of advanced treatment process lead consumer's needs to more high functional, clean and healthy goods. Moreover, increasing in the concern of eco-friendly material and processing, it has been getting popular that the dyeing method like as using natural dyes is more eco-friendly and natural-friendly treatment process. The method, used in this study, adhesion by binding with micro-capsulized natural material to fabric has low change in quality by external influence and high ability in spray effect by broken capsule which comes to pressure and friction when it dressed. Also it has wide application from natural fiber to synthetic fiber. The purpose of this study is development of multi-functional synthetic material with micro-capsulized Scutellaria baicalensis on PET. Moreover, it was driven by comparison of colormetric properties and fastness between regular dip-dyeing method and binding with micro-capsulized material method. Dye ability was arranged mostly low exhaustion but the PET treated by micro-capsule was more or less better than the dip-dyeing PET. Through the SEM(Scanning Electron Microscope) of PET treated by micro-capsule, it has good residence of capsules even after 5 or 10 times washing. Wash and light fastness was arranged some different grade by each condition but mostly high achievement and the micro-capsulized PET was more improved than regular dip-dyed PET.

Objectives: The aim of this study was to examine factors influencing job embeddedness in dental clinic hygienists. Through this study, we suggest the necessity to increase job embeddedness and use that as basic data for effective dental personnel management. Methods: A self-reported questionnaire was filled out by 219 dental clinic hygienists from September 8 to October 8, 2018. Data were analyzed using SPSS 20.0. Independent t-test, oneway ANOVA, Scheffe’s post-hoc test, and Pearson correlation coefficient were reviewed, and a multiple regression analysis was conducted. Results: Dental hygienists scored 3.14 points in job embeddedness. The variables that influenced clinical job embeddedness were self-efficacy, organizational commitment, and job satisfaction. These factors had 56.7% of variance in dental clinic hygienists. Conclusions: Job satisfaction was the most affected factor for dental clinic hygienists.

Clothes and environments as one system. Clothes play their role in adjustment to various environments and should be studied with humans as a research. The purpose of this study was to compare the wearing sensation depending on four different kinds of summer girls' high school uniforms on different cotton/polyester/polyurethane blend ratio for the different elasticity. The experiments were conducted to measure the comfort sensation. For this experiment, 4 healthy female students were taken as subjects. We checked the regional skin temperature, physiological responses(body temperature, blood pressure and pulse rate), subjective sensations(thermal, humid and comfort sensation) at 25℃, 65% R.H. The results are as follows: 1. The skin temperature of forehead and abdomen were continuously high, but those of forearm and leg were irregularly changed. 2. In the mean skin temperature, the more elasticity was, the lower it was. 3. Body temperature was slightly increased, however, the range of the increase was very little. 4. In the microclimate of all experiment clothes, the temperature and humidity in the back part of human body were higher than those in the back part. 5. The thermal sensation for the lowest elastic material was better than the others. The humid sensation was similar in four different materials. And The comfort sensation for the higher polyurethane blend ratio was better than the others.
