The purpose of this study was to evaluate the long term effect of school-based oral health program on decrease of dental caries among elementary school children. The subjects of this study were total 727 students of one elementary school in Deagu, Korea. They had received school-based oral health programs for more than one year since 2004. This school-based oral health program included regular oral examination, fluoride mouth-rinsing, pit-and-fissure sealing, APF gel application, tooth brushing instruction and take the xylitol tablet after lunch during school days. The subjects' oral health status were examined by two calibrated dentists every year from 2004 to 2009. The DMFS index of $1^{st}$ grade to $6^{th}$ grade experimental and control group was 0.07, 0.39, 0.55, 0.67, 0.81, 1.79 and 0.31, 0.86, 1.07, 1.04, 2.71, 3.08 respectively. It's significantly different in $5^{th}$ grade(p<0.001) and $6^{th}$ grade(p=0.018) when it compare with control group. This study partially showed effect of school-based oral health programs on decrements of dental caries. This program should be expanded widely among elementary school in Korea. Xylitol tablet also recommended to included in school-based oral health programs.

BACKGROUND/OBJECTIVES: The role of a school's nutrition environment in explaining students' eating behaviors and weight status has not been examined in an Asian setting. The purpose of this study was to create a school nutrition environment index and to pilot test the index in elementary and middle schools in urban South Korea. SUBJECTS/METHODS: This study used a mixed-methods approach. Environment assessment tools were developed based on formative research, which comprised literature reviews, in-depth interviews, and focus group discussions. Key elements from the formative research were included in the assessment tool, which consisted of a structured survey questionnaire for school dietitians. Fifteen school dietitians from 7 elementary and 8 middle schools in Seoul completed the questionnaire. RESULTS: The formative research revealed four main sections that guided a summary index to assess a school's nutrition environment: resource availability, education and programs, dietitians' perceptions and characteristics, and school lunch menu. Based on the literature reviews and interviews, an index scoring system was developed. The total possible score from the combined four index sections was 40 points. From the 15 schools participating in the pilot survey, the mean school nutrition-environment index was 22.5 (standard deviation ${\pm}3.2$; range 17-28). The majority of the schools did not offer classroom-based nutrition education or nutrition counseling for students and parents. The popular modes of nutrition education were school websites, posters, and newsletters. CONCLUSIONS: This paper illustrates the process used to develop an instrument to assess a school's nutrition environment. Moreover, it presents the steps used to develop a scoring system for creation of a school nutrition environment index. As pilot testing indicated the total index score has some variation across schools, we suggest applying this instrument in future studies involving a larger number of schools. Future studies with larger samples will allow investigation of the validity and reliability of this newly developed tool.

Objectives: This study was designed to understand the oral health fact of high school students, search for an education method and learning goal appropriate for the subjects, and utilize them as basic data to think of effective solutions for oral health care. Methods: The samples to achieve the purpose of this research are composed of 386 students in J industrial high school, OO city, Kyounggido, the number of male students 286, and female students 100. Data were statistically analyzed by frequency analysis, cross tabulation by using SPSS WIN Ver. 12.0. Results: First, The answers in terms of oral symptoms were in the order of 31.8% for gum hurt and bleeding, 31.4% for pain in teeth by drinking or eating hot and cold drinks or food, 27.1% for broken or cracked teeth, 25.7% for aching and throbbing teeth, 20.6% for unpleasant mouth smell, and 5.7% for pain of tongue and soft oral tissues. Second, In terms of behavior for oral health, 88.4% answered that they consume cariogenic snacks, while 29.2% of them, 2.5% of male and 6.3% of female enjoy consuming them but hardly brush their teeth after consumption. Third, In terms of timing for brushing teeth, the results show that 50.0% do so before breakfast, 47.9% after breakfast, 15.2% after lunch, 36.9% after dinner, 65.5% before going to sleep, and 3.5% after consuming snacks, whereas 64.2% answered that they are not aware of fluorine mouthwash. Fourth, In terms of oral health condition. proportion of children with one or more caries in permanent teeth was 71.0%, while 51.4% have $2{\sim}3$ cariogenic teeth, and 16.8% have more than 4 cariogenic teeth. Considering sex, female students have somewhat higher ratio showing 68.5% for male and 78.0% for female, but the ratio was 53.1% for male and 46.7% for female in case of $2{\sim}3$ cariogenic teeth, and 17.5% for male and 15.8% for female in case of more than 4 cariogenic teeth. 9.3% of students turned out to have decayed teeth. Fifth, In terms of oral hygiene condition, only 7.9% of them had excellent condition, and 38.4% need to improve. More specifically, 41.1% of male students and 30.6% of female students need to improve their oral hygiene condition. Conclusions: The study results suggest that School Dental health programs increase and need to be community-incorporated and comprehensive from elementary to high school.

Objectives : This study examined the oral health behavior and dental services utilization of adolescents in order to provide information on how to disseminate the correct oral health behavior to the youth and develop programs for the approach. Methods : The raw data of 'The Third 2007 Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analyzed. All survey data collected was processed using SPSS ver 17.0 for data analysis as Frequency analysis, chi-square and Logistic regression analysis. Results : 1.The adolescents who have parents with college degree are 70% higher of dental services utilization than the adolescents counterpart(whose parents don't have degrees). And also the adolescents living in cities are 1.3 times higher use of dental services than others living in countries. 2. In case of drinking soda, students having soda 4 days per week on average are 1.2 times higher use of dental services than who don't. 3.The students brushing teeth after lunch are 0.9 times lower use of dental service than who don't. And the students who have tooth ache whenever they have a meal are 1.6 times higher use of dental service than the students who don't have tooth ache. The students who had a dental health education are 1.4 times higher utilization of dental service than who don't. The difference of using dental service between the students who have gum disease and halitosis and the students who don't is almost none. 4. The students who drink alcohol and smoke 10 days more or less a month are 0.8 ~ 0.9 times lower use of dental service than who don't. Conclusions : The rate of utilizing dental service is higher at students who live with parents having college degrees and the more have oral health behavior, the less use of dental service for treatment. We concluded that more educational program should be developed and vitalized so that students can have oral health.

Objectives : The purpose of this study is to identify differences in time, frequency, and methods of toothbrushing according to knowledge acquirement of oral health between first and third year dental hygiene students who had relatively sufficient oral health education and students majoring non-health related field who had less opportunities of oral health education, to emphasize importance and necessity of the education, and to present basic data for development of effective programs of oral health education. Methods : 2,032 dental hygiene students and students majoring non-health related field attending 12 universities in Korea had been selected as subjects and were asked to complete a self-administered survey time, frequency, and methods of toothbrushing. The SPSS 12.0 program was used for statistical analysis of the collected data, and the significance of difference by groups was tested by using chi-square test, the one-way ANOVA and independent t-test. The mean frequency of toothbrushing per day and the rate of toothbrushing before and after meal were analyzed by using of multiple comparisons through the Scheffe test as post hoc test. Results : The rate of toothbrushing after lunch was 60.2% in third year and 39.2% in first year dental hygiene students, 20.3% in students majoring non-health related field, respectively. The mean frequencies per day of dental hygiene students were 3.33 times in third year and 2.85 times in first year dental hygiene students, 2.46 times in students majoring non-health related field, respectively. The rate of toothbrushing after meal among total frequency of toothbrushing per day was 85.36% in third year and 84.81% in first year dental hygiene students, 77.90% in students majoring non-health related field, respectively. As for the methods of toothbrushing, 'Turning up and down' was 68.8% in third year and 43.1% in first year dental hygiene students, 30.6% in students majoring non-health related field, respectively. Conclusions : Oral health education through dental hygiene course may improve the oral environment management of dental hygiene students and oral health education on toothbrushing should be strengthened for the students majoring non-health related field.

Objective: In this study, the dental health care knowledge, dental health behaviors and dental health status of elementary school students were compared and analyzed in the cases of their schools having dental health care center or not one. Methods: The target groups were 167 students of A school (experimental group) where pit-and-fissure sealants, fluoride mouthrinsing, and fluoride gel application were carried out with all grades of students by school dental health care center and 158 students of B school (control group) where fluoride mouthrinsing, for all grades students and pit-and-fissure sealants for the first grade students are carried out but have no the school dental health care center. Results: This study was carried out through the answer sheets and recordings of dental inspection. The findings of this study are as follows: 1. The dental health care knowledge was compared and the results showed that on average 14.2$\pm$2.1 in experimental group and 14.0$\pm$1.9 in the control group were no significantly different (p>0.05). 2. The dental health behaviors were compared and the results showed that the experimental group was significantly different(p<0.05) in terms of the number of times of dental brushing a day, the method of tooth brushing, the time of tooth brushing, the experience of tooth brushing with fluorine, the kinds of snacks and tooth brushing in school after lunch. But there was no significant difference(p>0.05) in the time of tooth brushing and the tooth brushing after eating snacks. 3. The DMF rate was compared and the results showed the significantly difference between the average experimental group and 53.8$\pm$5.0 in the control group(p<0.05). 4. The DMFT index was compared and the results showed the significantly difference between the average 0.6$\pm$2 in the experimental group and 1.4$\pm$1.6 in the control group(p<0.05). 5. The DMFI rate was compared and the results showed the significantly difference between the average 4.2$\pm$8.3 in the experimental group and 9.5$\pm$11.0 in the control group. (p<0.05). 6. The DT rate were compared and the results showed the significantly difference between the average 10.2$\pm$29.5 in the experimental group and 32.4$\pm$44.0 in the control group(p<0.05). 7. The FT rate were compared and the results showed the significantly difference between the average 88.5$\pm$31.0 in the experimental group and 67.5$\pm$44.0 in the control group(p<0.05). Conclusions: Based on the results, above there was no significant difference in dental health care knowledge between both the experimental and the control group. But we discovered that the experimental group is better than the other one in dental health care behaviors and dental health status. Therefore, we could conclude that the school dental health care center efficiently carried out the dental care and treatment. As school dental health care centers did not work out efficiently in terms of their educating on the dental health acre knowledge, the related programs to be developed and supported.

The purpose of this study was to investigate the food behaviors and food preferences of teenagers by regional groups. The subjects were composed of 365 third grade students in middle schools from urban, rural and fishing areas in Kyungpook province. The data was collected by using a survey questionnaire. The results of the study are summarized as follows: Eating habits of 21-47% of the subjects, according to the regions, were poor and female students in large city showed the best eating habits while female students in fishing village showed the poorest eating habits. Out of the three regional groups studied, the subjects from the fishing villages had the highest rates of skipping meals and eating between meals. Out of all the people investigated, thirty to forty percent had unbalanced diets, the highest percentage coming from the urban areas and the lowest from the fishing villages. All together an allergic reaction to food was the highest in the fishing villages' subjects and female students were more sensitive compared to the male students. Students from the urban area had higher frequency of symptoms of lactose intolerance. Upon the investigation of the subjects 'food preferences, they preferred boiled rice to any other rice as a staple food. Cha jang myun was the most preferred out of all noodles and breads. It was found that teenagers preferred one course meal such as fried rice to a rice-centered regular meal. Out of all various meat soups, beef soup and beef-rib soup were preferred the most. As for subsidiary foods the most preferred were soybean paste stew and cuttlefish stew which they ate daily. There was a very high preference for fried foods, the most favored being pork cutlet followed by fried vegetables, sweet potatoes, and minced meat. The most preferred cooked vegetables were bean sprouts and seasoned cucumber. Seasoned cubed radish roots were the most preferred kind of kimchi. For desserts there was a very high preference for the following fruits: apples, plums, strawberries, and oranges. For beverages the most popular choice were chocolate drinks followed by orange juice, apple juice, milk and tomato juice. According to these investigations, most teenagers liked daily foods which they are used to. The study showed that on the whole the teenagers had poor eating habits. A problem that needs immediate attention is that female students and students from the fishing villages have a high rate of skipping meals. It is expected that the results of this food preference test of teenagers could be useful in the meal planning of middle school lunch programs in the future.

Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B₆, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions: This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

The purpose of this study was to investigate the performance of elementary school dietitians in terms of nutrition education in the northern portion of Gyeonggi province. Self-administered questionnaires were given to 50 dietitians who have worked in elementary schools with self-operation food service, and 35(70%) dietitians returned the questionnaires. The results are summarized as follows: no students took part in nutrition education as a regular course, but all dietitians performed nutrition education in passive ways, such as 'using home correspondence'(39.0%), 'bulletin board/poster'(22.0%), 'using the internet'(13.4%) and 'indirectly through a classroom teacher'(12.2%). Most respondents performed nutrition education 'one time/month'(66.0%) or 'one time/week'(20.0%). The respondents thought that suitable teaching times for nutrition education were 'during a related subject'(35.5%), 'during lunch time'(22.6%) rather than 'during an independent subject'(16.1%). Most of the dietitians(94.3%) did not perform nutrition counseling because of 'a lack of opportunity'(72.7%) and 'workload'(27.3%). Additionally 88.6% of respondents did not have the time of for nutrition counseling for parents because 'am not a teacher'(56.7%) and 'workload'(30,0%). Information sources for nutrition education were mainly 'internet'(71.4%) and 're-educationa1 materials'(17.1%). They possessed instructional materials in the forms of 'printed materials'(35.1 %), 'exhibition/bulletin board'(31.2%), and 'electrical materials'(33.8%), 'but did not have 'solid materials' such as food models and dolls. Generally they had mostly 'leaflets'(82.9%), 'bulletins'(68.6%), 'internet'(57.1%), and 'CDs'(57.1%). Preferences for instructional materials used were 'printed materials'(46.2%), 'exhibition/bulletin board'(36.5%), and 'electrical materials'(17.3%) 'Leaflets'(80.0%) were mainly used; 'CD'(17.1 %) use was low compared to the proportion possessing CDs. The topics frequently chosen by the subjects for nutrition education were 'table manners'(82.9%), 'basic concepts of food and nutrition'(80.0%), and 'proper food habits'(80.0%), but the topics helpful for practical use, such as 'how much do I eat'(20.0%) and 'nutrition labeling'(37.1%), were not included frequently. The respondents thought that 'eating only what they like'(60.0 %), 'intake of processed foods'(17.8%), and 'obesity'(17.8%) were the most common nutritional problems among elementary school children. They also thought that establishing a regular course for nutrition education was an effective way to cut down on these nutritional problems. In conclusion, nutrition education programs that are combined with effective instructional materials and practical topics should be developed. Additionally, it is recommended that dietitians act as teachers who participate in regular courses as soon as possible.

We study the sustainability of the current fiscal policy of Korea, and the effects of the social welfare policy expansion, which has been recently discussed among the political circles, on the government budget and the generational equity, using generational accounting. We follow the generational accounting approach, considering the fact that most of the social welfare policies are the entitlement programs, which imposes the limitation of the policy maker's discretion to control the cost of their provision. The social welfare expenditure will change due to the change in the policy environments of the future, such as population aging. Therefore, we need to take into account the government cash flow of the future as well as of the present to investigate its effects on the fiscal sustainability, which implies that the national debt or the budget balance is not a proper index for the investigation. Our findings are as follows. The current fiscal policies are not sustainable, and the long-term budgetary imbalance is shown very serious. The required tax adjustment, which is defined as the percentage change of tax burden required to attain the long-term budgetary balance, is very large. Unless the level of the government expenditure is properly controlled, the tax burden and the social contribution level will rise to the untolerable level. Moreover, the expansion of the social welfare policies, which has been discussed among the political circles, will substantially increase the fiscal burden of the future generations. Even though the provision of the free lunch to the primary and the secondary school students, the free child care, and the discounted college tuition do not increase the fiscal burden much, because their magnitude at present is not large and will decrease due to the decrease in the number of the newborns and the students resulting from the fall in the fertility rate, that of the free health care service will increase tax burden of the future generations very much, because the magnitude of the government expenditure needed at present is very large and the population aging will further increase the magnitude of the health care expenditure. The findings indicate that the structural reforms, to prevent the explosive increase in the social welfare expenditure in the future, are necessary before the implementation of the welfare policy expansion. In particular, the cost control of the social transfers to the elderly needs to be made, because the speed of the population aging of Korea is among the highest in the world. The findings also indicate that the budget balance or the national debt can cause the fiscal illusion, which makes the Korean government budget look sound, even though the fiscal policy will rapidly increase the social welfare expenditure in the future, as the population ages. The generational accounting, which takes into account the cash flow of the future as well as of the present, unlike the budgetary balance and the national debt, which shows the results of the government financial activities of the past and the present, is a useful method to overcome the fiscal illusion.
