Objectives: The purpose of this study was to compare the general health status and oral health status based on periodical dental preventive experience, and to find methods for regular dental prophylaxis, using the data obtained from the $7^{th}$ National Health and Nutrition Survey. Methods: This study was performed using data collected from the $7^{th}$ National Health and Nutrition Examination Survey (KNHANES). A total of 9,015 participants were selected for the study. Statistical analysis was performed using SPSS 21.0, with data obtained from a complex sampling design, and a significance level of 0.05 was set. General characteristics of the participants, oral health status, and recent preventive dental treatment were examined for a complex sampling frequency analysis, and the differences in distribution were analyzed using chi-square test. Results: The group that recently under went dental prophylaxis, when compared to the group that had not under gone dental prophylaxis recently, reported several 'no obstacles' for all items of the EQ-5D (p<0.05). Moreover, the group that recently underwent dental prophylaxis used all the oral care products (p<0.05). Conclusions: It is necessary to actively expand institutional supervision so that regular dental preventive measures can be undertaken to promote oral health that affects general health.

This study was performed to investigate the relationship between milk and milk product consumption and dietary nutrient intake among Korean adolescents. Questionnaire survey and 3-day diet survey using the food record method were completed by a total of 664 subjects. Subjects were divided into three groups, Q1 (low group), Q2 (middle group), and Q3 (high group), according to dairy equivalent of calcium. Dairy equivalent of calcium was determined by the amount of calcium eaten from milk and milk products by individual subjects. As a result, the ratio of school milk service was higher in Q3 (P<0.001). The most frequent answer about the reason for consuming milk and milk products was 'to be taller' followed by 'good taste' and 'health promotion'. Preference for all types of milk such as white-, enriched-, and flavored-milk was higher in Q3 followed by Q2>Q1 (P<0.05). Ratio of mean daily dietary nutrient intakes of dietary fiber, vitamin C, folate, and calcium to RNI was lower than 2/3 for all of the groups. These mean daily dietary nutrient intakes were significantly higher in Q3 (P<0.05), and in particular, mean daily dietary calcium intake, which was the lowest nutrient consumed by Korean adolescents, was also the highest in Q3 followed by Q2>Q1 (P<0.05). The above results suggest that the school milk program is very helpful in encouraging adolescents to consume milk and milk products and consequently ensure their optimal nutrition. Therefore, we should try to encourage adolescents to participate in the school milk program more actively through nutritional education and government policy.

This study attempts to propose a priority of national nutrition targets and strategies for health promotion by the year 2000 in Korea, as a part of the task set for national health promotion objectives and strategies. Among all of the important health issues raised, ten were chosen, nutrition was one priority area. In the first part, the current status of the nutrition-related health problems and risk factors are reviewed, in conjunction with the newly arisen health phenomena, such as changes in prevalence of lifestyle disease and causes of death, changes of food consumption patterns in our country. In the second section this study suggests six feasible national nutrition targets, eight implementing strategies and current major tasks on the basis of the assessment of present status and in consideration of the other health promotion goals and strategies, with reference to that of other developed countries. The main targets and strategies are suggested as follows ; Firstly, the national nutrition monitoring and surveillance system should be established for identifying the nutritional problems for our people, and current National Nutrition Survey is a strong need for improvement to a more comprehensive and reliable one. Secondly, effective administrative mechanism should be operation at national level for the development of nutrition policy. Ministry of Health and Welfare (MOHW) as well as local health department must be remarkably renewed and strengthened the nutrition section. And it is recommended that MOHW organize and operate “The Council of Nutrition”, in which all government authorities related with foodstuffs and nutrition would incorporated. The Council of Nutrition would act as an adjustor as well as a coordinator in nutrition related policy-making. Thirdly, healthy eating pattern will be supported by activities of introducing a nutrition labeling for providing consumers with the necessary information and skills for food selection. Fourthly, nutrition education, and nutrition intervention programs will be carried out in various settings such as health centers, schools, and clinical fields and workplace. Fifthly, the current dietary guidelines shall be continuously improved in detail, and publicly circulated to particular levels of people by age group and by health condition. And finally, researches and epidemiological studies particularly in regard to diet for development of chronic diseases are needed for more investigation and up-to-date national health and nutrition data should be collected with the support and cooperation from the various medical professional teams .

The purpose of this study was to investigate the nutrient intake status and factors affecting the consumption of commercial staple food for Korean adults using the Korean National Health and Nutrition Examination Survey data from 2010 to 2014. As a result of analyzing the frequency of consumption of commercial staple food, in 27.578 subjects, 75.5% of them did not eat it once a day, 21.7% of the subjects consumed once a day, and more than two times showed 2.8%. According to the results of age, the higher the age, the higher the rate of not consuming commercial staple food, and the lower the age, the higher the rate of consumption of commercial staple food(p<0.0001). In addition, the rate of consumption of commercial staple food was higher in cities than in rural areas. The higher the education level, the higher the proportion of commercial staple food. The intake of rice, noodles, and bread increased significantly as the frequency of consumption of commercial staple foods increased. Protein, fat, riboflavin, and niacin showed significant differences with increasing frequency of commercial staple food in nutrient intakes(p<0.0001). As the number of commercial staple food increased, the intake of grains, egg products, milk and dairy products, beverages and other food groups increased and the consumption of vegetables decreased significantly.

Cloud computing is an internet-based technology, providing services to the virtualized IT environment, and allowing users to add or remove resources of hardware or software at their discretion. Since Cloud computing can construct virtually integrated environments out of multiple local computing environments, various information services can be provided by it. In addition, state organizations also strive to build the cloud computing environments due to the benefits of reduced costs to introduce the system and of reduced time to build and provide the IT services. This study suggests a web-based cloud computing system for the computing environments, to be applied for the Korean National Health and Nutrition Examination Survey (KNHANES) by the Ministry of Health and Welfare, Republic of Korea.

Objectives : The purpose of this research is to use data from the third year of the 4th National Health and Nutrition Examination Survey to study relationship between oral disease and chronic disease that generally persist from 6 months to over a year, or more specifically, circulatory disease, diabetes, and osteoporosis. Methods : Of the data from the third year of the 4th National Health and Nutrition Examination Survey, 7,893 adults over 19 years old who completed medical examination, health survey, and nutrition survey were selected as the final research subjects. Relationship between chronic disease and oral disease was analyzed by cross tabulation (2-test) and logistic regression analysis using SPSSWIN ver 18.0. Results : 1. Differences in the rate of prevalence of periodontal disease and the rate of prevalence of missing teeth were statistically significant with respect to age, gender, marital status, education level, residential area, income level, and occupation. Rate of prevalence of dental caries was statistically significant with respect to age, education level, and income level. 2. After examining the relationship between existence of chronic disease as diagnosed by doctor with oral disease, rate of prevalence of periodontal disease and missing teeth, hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis showed statiscally significant difference. 3. Examination of rate of prevalence of chronic disease with respect to oral disease, periodontal disease and missing teeth exerted statistically significant influence on hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis (p<0.05), while dental caries did not have statistically significant effect. 4. Analysis of coupling effect of periodontal disease and missing teeth on chronic disease showed that they were related in all chronic diseases examined in this study (hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis) (p<0.05). Conclusions : Periodontal disease and missing teeth were found to increase the rate of prevalence of chronic disease.

Koreans have undergone many changes in dietary patterns with economic growth. The purpose of this research was to examine changes in dietary patterns using data from the 1998, 2001, and 2005 Korean National Health and Nutrition Examination Survey. The study included 21,525 subjects (8,295 from 1998, 6,880 from 2001, and 6,350 from 2005) who were 20 years or older and who participated in a 24-h diet recall. The percentage energy intake from 22 food groups was calculated, and a cluster analysis was applied to identify dietary patterns. Two dietary patterns emerged; the first pattern was characterized by high intake of white rice, legumes, vegetables, kimchi, and seaweeds, the so-called "traditional" pattern (53%), whereas the other pattern was characterized by high intake of other grains, noodle dumplings, floured bread, pizza, hamburgers, cereals and snacks, potatoes, sugared sweets, nuts, fruits, meat·its products, eggs, fish, milk and dairy products, oils, beverages and seasoning, or the so-called "modified" pattern. The modified pattern comprised a higher proportion of younger aged, metropolitan residents with more education and higher incomes. However, the gender distribution was not significantly different. The modified pattern had a significantly higher intake of all nutrients except carbohydrates and had a higher proportion of energy from fat and protein. No association with a risk for metabolic syndrome was found for either dietary pattern. After age was standardized, the traditional pattern included 52% of the respondents in 1998, 54% in 2001, and 50% in 2005. However, the modified pattern was significantly more prevalent in the younger age group (20-29 yr), whereas the traditional pattern increased significantly in the older age group (${\geq}$ 65 yr). In conclusion, a secular trend was found for dietary pattern by age group, suggesting that it is necessary to monitor the changes in dietary pattern by age group and to develop appropriate dietary education and guidelines.

There is little information on the nutrient intake according to the city size and small town in Korean elderly. This study analyzed the nutritional consumption of older people in metropolitan, middle and small cities, and rural areas according to four income levels. The recent data from the 2016~2018 Korean National Health and Nutrition Survey, Centers for Disease Control and Prevention were used. The final analysis included 4,325 individuals (Male: 1,856, Female: 2,469) over 65 years old. Multivariable regression with a complex sample design was conducted to compare the nutrient intake among the groups. In a comparison within regions, the nutrition status of the elderly in small towns was more vulnerable than metropolitan and middle & small cities. The energy intakes were similar between the groups. The carbohydrate intake of middle & small cities was significantly higher than the other regions. The intake of other nutrients in metropolitan and middle & small cities appeared to be higher than in rural areas. The number of nutrients with statistical significance between low and high-income levels were 19 in metropolitan, 11 in middle & small cities, and 5 in rural areas. Each contribution of carbohydrate, fat, and protein to the total energy intake was lower in the low-income level than the high-income level in metropolitan and middle & small cities. On the other hand, in rural areas, only the contribution of protein to energy intake was lower in the low-income level than the high-income level. Cities with higher levels of urbanization had more severe nutritional inequality in relation to the income level. There was also nutritional inequality present in rural areas but it was to a lesser extent. Moreover, the generally low level of nutrient intake was problematic in rural areas. These findings could be used as fundamental evidence for developing community nutritional policies for the elderly.

This study was conducted to survey the perception and preferences of customers that have dined at Korean restaurants in China and investigate the importance and performance level of quality attributes, customer satisfaction, revisit intention and recommendation intention. The survey was conducted January 31~March 1, 2016 in China. The 293 questionnaires (97.7%) were analyzed using SPSS(Ver. 23.0) and AMOS(Ver. 21.0). Results of this study are as follow: Customers that dined at a Korean restaurant in China were composed of 157 women and 136 men. Regarding the reason for preferring Korean cuisine, taste, hygiene and nutritional value of Korean food were the most significant quality factors. Regarding complaints about Korean food, Chinese people placed much emphasis on freshness of ingredients when dining out, based on the majority of complaints about ingredients that were not fresh. The main reason for leftover food were personal eating habits and that of customers revisiting food taste and nutrition. Path model among customer satisfaction, revisit intention and recommendation intention revealed the factor of menus and attributes of menu items regarding customer's age that had an impact on customers' satisfaction, and association with customers' satisfaction, revisit intention and recommendation intention as well.

BACKGROUND/OBJECTIVES: Observational studies suggest that an association between vegetable consumption and coronary heart disease (CHD). However, the results are inconsistent. This study aimed to investigate the daily intake of vegetables on a national level and its effect on the risk of CHD risk, as determined by the Framingham Risk Score (FRS). SUBJECTS/METHODS: This study was conducted a cross-sectional design of 2,510 male adults 40-64y of age who participated in the 2007-2009 Korean National Health and Nutrition Examination Survey. Daily intake of vegetable was assessed by 24-h recall, and the consumption frequency of vegetables was determined using a food frequency questionnaire. The odd ratio of CHD risk according to daily intake and frequency of vegetables was analyzed. RESULTS: Total vegetable intake was inversely and significantly associated with the risk of CHD (Model 1: 4th vs. 1st quartile, OR = 0.74, 95% CI = 0.58-0.96, P for trend = 0.0015), and the significant relationship with CHD risk remained even after adjusting for potential confounders (Model 3: 4th vs. 1st quartile, adjusted OR [aOR] = 0.69, 95% CI = 0.49-0.95, P for trend = 0.0492). Subjects in the higher quartiles of non-salted vegetable intake had 31% lower odds of the risk of CHD compared to those in the lowest quartile after adjusting for various potential confounders in model 3 (aOR = 0.69; 95% CI = 0.49-0.97, P for trend = 0.0478). No significant associations between the frequency of vegetable intake (total, green, white and red vegetable) and the risk of CHD were found. CONCLUSIONS: The major results of this study indicate that higher vegetable intake may help prevent CHD in Korean men.
