A self-administered survey was conducted in dental hygiene students at colleges or universities in Daegu and North Gyeongsang Province to provide basic data necessary to suggest standards for the direction of career for dental hygiene students and construct desirable image of dental hygienists. The data were collected from February to May 2013; with the exception of 46 questionnaires containing insincere responses, 1,679 were finally analyzed using SPSS/Win 18.0, drawing the following conclusion: The freshmen showed higher levels of regret for selection and enrollment recommendation than the sophomores, juniors, or seniors and the sophomores, juniors, and seniors showed higher levels of willingness to change courses than the freshmen; thus, those in lower grades showed higher environment satisfaction. As for desired career, regardless of grades, they showed higher preference for being employed as a dental hygienist; as for desired paths to get a job, the freshmen were more likely to get professors' recommendations and the sophomores, juniors, and seniors showed higher preference for open recruitment. They showed higher preference for getting a job in a large city because of greater possibility of improvement. As for the desired period of employment, regardless of grades, they showed higher preference for employment before getting married and for reemployment after their children grew up; as for desired workplace, the freshmen showed higher preference for a dental clinic in a hospital, whereas the sophomores, juniors, and seniors showed higher preference for a dental hospital. As for the differences in image of dental hygienists by grades, the freshmen and sophomores showed higher levels of attitudes than the juniors; the freshmen and sophomores showed higher levels of beliefs than the juniors or seniors; and the seniors showed higher levels of values than the freshmen, sophomores, or juniors, and the sophomores and juniors showed higher levels of values than the freshmen; thus, students in lower grades showed higher levels of attitudes and beliefs and those in higher grades showed higher levels of values. Such factors of enrollment satisfaction as willingness to change courses and persuasion to make enrollment had significant effects on image of dental hygienists. Dental hygiene students need to make efforts to establish a job identity and get desirable image of dental hygienists and to make constant efforts to promote more accurate and positive image of dental hygienists through systematic and positive public relations.

BACKGROUND: Wicheon watershed has the largest irrigation area among the mid-watershed of Nakdong river. However, no investigation of irrigation water quality has been conducted on the Wicheon watershed, which evaluates the effects on the soil quality and crop cultivation. Therefore, this study aims to provide various assessments of water quality of Wicheon watershed as the scientific basic data for efficient agricultural activities. METHODS AND RESULTS: Water sampling was performed in five locations of the first tributaries of Wicheon. Wicheon watershed showed clean water quality with very low organic matters and safe water quality from metals at all points of investigation. It was estimated that the natural chemical components of Wicheon watershed were originated from water-rock interaction in Gibbs diagram. All samples were concentrated in the type of Ca-HCO₃-Cl in the Piper diagram. The quality of irrigation water was evaluated with sodium adsorption ratio (SAR), residual sodium carbonate (RSC), permeability index (PI), and percent sodium (%Na). The values of these water quality indices were in the range of 0.37-0.67, -2.11--0.24, 41.13-84.52% and 11.28-21.84%, respectively, and were classified as good grades at all sites. CONCLUSION: The water quality of Wicheon watershed was very low in salt, indicating good irrigation water suitable for growing agricultural products. We hope that the results of this study will be used as the basic data for the cultivation of agricultural products and promotion of their excellence.

Objectives: This study was conducted to identify the awareness and practice of reducing sugar in school meals and the status of nutrition education regarding sugar reduction. Methods: An online survey was conducted on 101 nutrition teachers (dietitians) working at elementary, middle, and high schools in Daegu. Results: School nutrition teachers in Daegu recognized the need for efforts to reduce the sugar intake in the Korean diet, and it was found that elementary nutrition teachers were more aware of the implementation of the sugar reduction policy at the national level than middle and high school nutrition teachers (P = 0.002). Among the policies to reduce sugar intake at the national level, there was a high need for the promotion of self-control and limiting the sales of food with high sugar content in schools and their vicinity. The degree of practice for reducing sugar in school meals was found to be higher in the preparation, purchase, and cooking stage compared to the serving stage (P < 0.05). There was a high need for changing the preferences of the subjects for a sweet taste as a means of reducing the sugar in school meals. Thirty-six percent of nutrition teachers conducted sugar reduction education, and sending out school newsletters was the highest type of nutrition education at 80.6%. Conclusions: To effectively promote reduced sugar intake in school meals, it is necessary to change the preference of the subjects for sweetness and to conduct continuous education that can improve the awareness of people for reducing their sugar intake. For this, it is necessary to set aside time for nutrition education and to prepare an institutional framework for providing this education.

Background: This study aims to examine changes in fraudulent claim counts and total reimbursements before and after enhancements in counterfeit claim controls and monitoring of provider claim patterns under the "Proactive self-audit pilot program of fraudulent claims." Methods: This study used the claims data and hospital information (July 2021-February 2022) of the Health Insurance Review and Assessment Service. The data was collected from 1,129 hospitals assigned to the pilot program, selected from the providers who filed a claim for reimbursement for intravenous injections. Paired and independent t-tests, along with regression analysis, were utilized to analyze changing patterns and factors influencing claim behaviors. Results: This program led to a reduction in the number of fraudulent claims and the total amount of reimbursements across all levels of hospitals in the experimental groups (except for physicians below 40 years old). In the control group, general hospitals and hospitals demonstrated some significant decreases based on the duration since opening, while clinics showed significant reductions in specified subjects. Additionally, a notable increase was observed among male physicians over the age of 50 years. Overall, claims and reimbursements significantly declined after the intervention. Furthermore, a positive correlation was found between hospital opening duration and claim numbers, suggesting longer-established hospitals were more likely to file claims. Conclusion: The results indicate that the pilot program successfully encouraged providers to autonomously minimize fraudulent claims. Therefore, it is advised to extend further support, including promotional activities, training, seminars, and continuous monitoring, to nonparticipating hospitals to facilitate independent improvements in their claim practices.
