The purpose of this study was to delve into how to provide better and more oral health education to middle school students, and to boost school oral health projects. The subjects in this study were 430 middle schoolers. After their oral health awareness, knowledge and oral health care were investigated, the following findings were given: 1. Concerning concern for oral health, 56.7 percent were oral health conscious, and as many as 43.2 percent were little or never concerned about it. 2. As to subjective oral health status, 36.7 percent found their own oral health status to be good, and 63.3 percent had a periodontal disease or felt that there was something wrong with their oral health. Regarding self-assessed abnormal oral symptoms, 25.8 percent considered themselves to have an abnormal symptom related to temporomandibular joint, and approximately 30 percent thought there was something wrong with their gums. 3. As for toothbrushing habits, the number of the girls who brushed their teeth after lunch was statistically significantly far larger than that of the boys who did. There were some differences between the boys and girls in toothbrushing method and in which part of the oral cavity they brushed. 4. In regard to oral health knowledge, the girls(a mean of 7.05) significantly excelled the boys(6.36). Those who were more oral health conscious got significantly better scores in oral health knowledge. 5. In terms of dental-clinic visit experiences, the students who had ever visited a dental clinic took in less sugar and got a more frequent regular dental checkup(2.62, 2.50) than the others who hadn't(2.32, 1.74).

The aim of the present study was to examine the relationship of maternal factors such as knowledge, attitude and practice of weaning with infant feeding. The subjects were 103 mothers visiting a public health center in Gumi, Kyungbook who filled out self-administered Questionnaires. First of all, about $90\%$ of the participants recognized the importance of complementary foods and proper weaning practices. The response for the recognition of the importance of infant weaning process showed a significant difference by education levels. Concerning an appropriate time for the introduction of weaning foods, $53\%$ of mothers had commenced weaning at age $4\~6$ months, while $38\%$ had done so at age $6\~8$ months. Approximately $76\%$ of mothers fed their babies without the knowledge of age-related weaning method and type of weaning foods. There were no statistical differences in maternal weaning knowledges between levels of education and house income. Mothers with higher levels of education and family income tended to show high perception scores regarding possibility of food allergies caused by baby foods. A demand for reliable sources and education related to nutritious weaning foods and weaning practices were strong in the group with higher education. Knowledge of weaning method and baby foods were obtained by 59 of the 103 mothers from mass media, 35 from friends caring babies, and 9 obtained advice from health professionals or family. Advice from the heath professionals was not the main influence on their decision to introduce weaning foods. Although commercial baby foods are the most commonly used as first weaning foods, those with higher education groups considered commercial baby food are not nutritionally better than home-maid foods. The current findings suggest to us that to improve weaning process, mothers should be educated on the selection and preparation of nutritious, balanced weaning foods and on good weaning practices. It is advised that supportive health professionals from community public health centers should lead the education of infant feeding practices based on maternal characteristics and on basic food and nutritional knowledge.

This study aims to examine the knowledge level of culinary staff members regarding the restaurant country- oforigin labeling system by developing a scale to investigate and evaluate such knowledge levels. The empirical study targeted culinary staff members with over 7 years of experience in 10 luxury hotels in Seoul who were approached through the convenience sampling method, which was conducted for 14 days from November 14th to 27th, 2014. A total of 192 self-administered questionnaires were collected, of which 186 questionnaires(93%) were used for the final analysis. For investigation and analysis, a frequency analysis was carried out to look into population statistics and the level of knowledge using the SPSS 18.0 statistics program. One-way ANOVA and t-test were carried out to investigate differences in knowledge levels of restaurant country-of-origin labeling system with reference to academic background, job position, and hotel management type. As the result, the average correct answer rate of the culinary staff members for a total of 21 questions was 39.85% and there were no significant differences based on the academic background. However, the correct answer rate was higher for respondents that held high positions and had independently managed hotels, suggesting that knowledge varied depending on job position and management type. In conclusion, it is suggested that in order to improve the level of knowledge of the restaurant country-of-origin labeling system among culinary staff members there is a need to enhance training and continuous supervision to apply the knowledge to work in future. In addition to this, this study discussed the limits of the study and the orientation of further research.

The study aims to examine the knowledge and awareness of care workers on oral health knowledge at the geriatric care facilities in order to improve and develop oral health services. For the research method, the study carried out a questionnaire survey to 163 care workers working at the geriatric care facilities (10) in D Metropolitan City from May 1~31, 2015 and then the collected data were statistically analyzed. As a result, the oral health knowledge of care workers was 20.09 points out of total 26 points (77.2%). The highest knowledge was 'proper toothbrushing method' with 93.0% and the lowest one was 'knowledge on the use of oral supplementary goods' with 58.1%. Those with experience of oral health education had higher demand on oral health education (P<0.001), and those with higher experience of oral health education had significantly higher oral health knowledge (P<0.001), demand (P<0.01) and awareness (P<0.05). As for factors influencing care workers' oral health awareness, if they had higher oral health knowledge points (P<0.01), oral health education demand (P<0.01), they had higher oral health awareness level. Accordingly, it is required to provide efficient, sustainable and practical oral health education of care workers considering oral characteristics of the long-term hospitalized patients at the care hospital. And, the role of dental hygienist as the person in charge of oral health education is necessary. Therefore, institutional support from the government is required to assign professional personnel.

Due to differences in singing styles and voice production between classical and popular music singers, their knowledge and practice regarding vocal hygiene may differ. This study compared the knowledge and practice of vocal hygiene among 121 university undergraduate students (58 classical and 63 popular music vocal majors). Additionally, the correlation between the level of knowledge and practice of vocal hygiene and the subjective voice evaluation was examined. The results revealed that both knowledge and practice of vocal hygiene were significantly higher in classical than popular music vocal majors, and that vocal hygiene practice was significantly higher than knowledge in the entire group. In addition, there was a weak positive correlation between knowledge and practice of vocal hygiene; and a weak negative correlation between vocal hygiene practice and subjective voice evaluation. This study suggests that popular music vocal majors have relatively lower levels of knowledge and practice in vocal hygiene than classical music vocal majors. It also highlights the need to provide tailored vocal hygiene education programs for both classical and popular music vocal majors, as they show low levels of knowledge and practice in certain aspects of vocal hygiene.
