Objective: The purpose of this study was to reduce the burden on dental hygienists in performing dental hygiene processes in the clinic. This study systematically analyzed dental hygiene problems and dental hygiene planning according to the oral condition of patients by applying an oral health care program based on the dental hygiene process. Methods: This study analyzed influential factors of 17 dental hygiene problems and 12 dental hygiene plans according to the oral health index and charts of 185 patients. This study was approved by the Institutional Review Board (IRB No. 1041449-201801-HR-003) of Silla University. The frequency of dental hygiene problems and dental hygiene planning was analyzed and correlations among the oral health index, dental hygiene problems, and dental hygiene planning were analyzed. Results: The higher the bleeding on probing score was, the more scaling was planned. The higher the calculus rate was, the more air-jet and jaw joint disorder prevention education was planned. The higher the O'Leary index was, the more dietary education and air-jet was planned. The higher the Simplified Oral Hygiene Index was, the more air-jet and jaw joint disorder prevention education was planned. The higher the Periodontal Screening and Recording index was, the more scaling and professional tooth cleaning was planned (p<0.05). Conclusions: The burden of oral preventive duties on dental hygienists will be minimized by systematically establishing problems and planning of dental hygiene according to patients' oral health index scores. Therefore, it is expected that dental hygienist can actively use the dental hygiene process in oral health care programs.

Various types of health functional foods (HFF) are popularly used among middle-aged. We surveyed 946 middle-aged in Korea for HFF use and significant variables for their HFF use including demographic characteristics, health related variables and nutritional beliefs. The use prevalence of HFF was 58.9%, and among all types of HFF, red ginseng products were taken most frequently, followed by nutritional supplements, ginseng products > mushroom products. HFF was taken more frequently in subjects from high monthly family income (p < .001), and in those from families with a high socioeconomic status (p < .001) in comparison to each corresponding group. Mean age of users was higher than nonusers (p < .001). Self concern about health (p < .001) and usage ratio of HFF by family (p < .001) were higher in users than in nonusers of HFF. Total dietary assessment score was not different in two groups, and users had a more positive view concerning the potential health benefit of HFF than nonusers (p < .001). Most users of HFF took HFF when they were healthy (52.8%) and experienced a little effect through the HFF use (51.2%). Most users of HFF obtained the information on HFF through family and relatives (30.5%) and most of them purchased HFF at pharmacy or oriental medicine clinics (44.5%). HFF users preferred multivitamin and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread use of HFF and inappropriate usage of HFF among subjects, the proper use of these products for the contribution to their optimal nutrition and overall health is a subject that should be formed through practical nutrition education considering the various variables affecting their HFF use.

Prevalence of allergic diseases is influenced by environment and dietary life. It is key to improve daily food life to relieve them. Food nutrition labeling is useful to do it by offering nutrition information. The purpose of the study is to find relationship between experience of diagnosis of allergic diseases and recognition of food nutrition labeling. The data of 4,928 people with experience on diagnosis allergic rhinitis, asthma, atopic dermatitis of 2016 Korea National Health and Nutrition Survey was used. According to the result of binary logistic regression analysis, those who had experience in being diagnosed with an allergy showed high awareness in food labels. There were differences between allergy diagnosis groups and allergy non-diagnosis in affecting factors of residence, income level, subjective health status and body-shape perception. Support measures are needed to enhance access and convenience to nutrition education and nutrition labeling to support nutrition labeling utilization.

The purpose of the present study was to evaluate the effects of different dietary concentrations of T-2 toxin on blood plasma protein content, lipid peroxidation and glutathione redox system of pheasant (Phasianus colchicus). A total of 320 one-day-old female pheasants were randomly assigned to four treatment groups fed with a diet contaminated with different concentrations of T-2 toxin (control, 4 mg/kg, 8 mg/kg and 16 mg/kg). Birds were sacrificed at early (12, 24 and 72 hr) and late (1, 2 and 3 weeks) stages of the experiment to demonstrate the effect of T-2 toxin on lipid peroxidation and glutathione redox status in different tissues. Feed refusal and impaired growth were observed with dose dependent manner. Lipid-peroxidation was not induced in the liver, while the glutathione redox system was activated partly in the liver, but primarily in the blood plasma. Glutathione peroxidase activity has changed parallel with reduced glutathione concentration in all tissues. Based on our results, pheasants seem to have higher tolerance to T-2 toxin than other avian species, and glutathione redox system might contribute in some extent to this higher tolerance, in particular against free-radical mediated oxidative damage of tissues, such as liver.

The purpose of this study was to investigate to the effect of regular exercise on nutrients intakes and energy balance related to food habit and nutrient knowledge of college women. This study was conducted from May to June in 2000. One hundred and forty female students made their three day dietary records by 24-hr recall method and one day activity record. The questionaires were designed to fine out food habit and nutrition knowledge status. The height. weight and blood pressure were measured and also body fat mass and lean body mass measurements were performed. The results obtained are summerized as follows. Average height and weight of E(exercise) group were found to be increased than those of NE(non-exercise) group. The percent of body fat and body fat mass(kg) in E group were slightly lower than those of NE group. Calorie intake of NE group was 1,664kca1 per day. This was composed of carbohydrate 60%kcal. protein 14%local and fat 24%local. Calorie, calcium, iron, vitamin A, vitamin B$_2$ and niacin intakes of NE group were lower than those of RDA and calorie intake of E group was 2.313kca1 per day. This was composed of carbohydrate 54%, protein 13% and fat 31%. Other nutrients such as iron, vitamin A, niacin and vitamin C were lower than those of RDA. Daily energy expenditure and physical activity of E group were 2,397.6$\pm$49.2kca1; 1,035.7 $\pm$36.5kcal, respectively and it was higher than those of NE group.

With the enlargement of school meals, the lunch program has played an important role in educating young students about good eating habits and food Preferences. The objective of this study was to investigate the awareness and preference of vegetables and to provide preliminary data required for framing a menu of school meals to help students maintain good food preference and eating habits with a balanced food diet. A survey was conducted from 25th October to 27th November, 2004 with 873 elementary school students (M: 474, F:399) in the 4th, 5th, or 6th grade of 6 schools in Daegu and Gyeong sang but do (Yongchon, Gumi, Pohang). Satisfaction for the school meal was rated by $52\%$ of the students and 'rice and soup' was the favorite meal type. Eating habits of students were not influenced by the employment status of their mothers. Only $11.2\%$ of students selected vegetable as their favorite food. Marsh mallow, taro stem, green bean sprouts, crown daisy and broccoli showed very low awareness and were selected as the least favorite vegetables. The most important criteria of preference were the taste and eating experience of the vegetables. The most preferred cooking method of the vegetables was tchigae which is a simple stew. Recognition of frequency for daily eating vegetables significantly affected the real intake of vegetables for everyday meals and the preference of vegetables also significantly affected the vegetable intake from the school meals. Compared to the school dietitian, mothers showed a greater frequency in being selecting as an educator of nutritional information. The above results indicated the need to improve the level of students' understanding of the importance of vegetables in the daily diet with parental education and publicity.

Cardiovascular disease has the highest mortality rate in South Korea. Previous studies have reported that serum cholesterol level relates to intake of dietary fat and cholesterol. Therefore, in this study we developed a semiquantitative food frequency questionnaire (FFQ) for Koreans with a high-risk of hypercholesterolemia and to validate the FFQ. Semiquantitative FFQ, which includes 160 food items, reflects intakes of energy, fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUPA), polyunsaturated fatty acid (PUPA) and cholesterol. We chose food items from the previous study of our research group (Suh 1999) which reported a nutritional status of Korean adults with normocholesterolemia, borderline and hypercholesterolemia. To validate the FFQ, we compared the results of the FFQ with those of a 3-day food record using a paired t-test. In addition, we calculated Pearson's and Spearmen's correlation coefficients. Intakes assessed by the FFQ and a 3-day food record were classified into quartile and the degree of agreement was obtained. Fifty-five participants responded for the validation study by completing both the FFQ and a 3-day food record. Pearson's correlation coefficients between estimated intakes by respective methods for energy, fat, SF A, MUPA, PUPA and cholesterol were 0.32,0.41,0.37,0.41,0.37 and 0.21, respectively. Spearman's correlation coefficients of energy, fat, SF A, MUPA, PUPA, cholesterol were 0.31, 0.44, 0.39, 0.46, 0.46, and 0.37, respectively. Nutrient densities in 1000kcal were compared. Pearson's correlation coefficient of cholesterol density increased and other values were similar with original values. The average degree of agreement was 67％ that intakes of energy, fat, SF A, MUPA, PUPA and cholesterol assessed by the FFQ and 3-day food records were classified within the same and the adjacent quartile. On the average, 8％ were misclassified into the extreme opposite quartile. The average of weighted kappa was 0.46. In conclusion, the FFQ developed in this study is considered to be a reliable tool to assess nutrient intakes for Koreans with a risk of hypercholesterolemia because the FFQ reflects the intakes of energy, fat, SFA, MUFA, PUPA, and cholesterol.

This study was conducted to investigate the evaluation of nutrition and exercise education program on weight control for obese children. The subjects of this study were 28 obese children and their parents living in Geyongnam area. The weight control program consisted of exercises for children and nutrition education for both children and their parents. The BMI values of the children were significantly reduced from $27.96\;kg/m^2$ to $27.22\;kg/m^2$ after 11 weeks (p < 0.001) and to $27.65\;kg/m^2$ after one year. Dietary habits and exercise patterns were also changed positively. For the children, while the frequency of eating breakfast and appropriate chewing habits were increased, the percentages of eating in inappropriate position and the frequency of buying snacks were decreased (p < 0.001). In terms of exercise, the proportion of doing exercise more than 30 minutes, participating in physical activity classes actively, and walking rather than taking a car were significantly increased. Nutrition knowledge of both the student and parent respondents were significantly increased when measured immediately after the education and even a year after compared to their knowledge status measured before the program (p < 0.001). Both the students (82.1%) and parents (96.4%) were satisfied with the overall weight control program. Exercise therapy was chosen as the most beneficial content. Reparticipation intention was comparable between the students (28.6%) and their parents (67.9%). A year after survey results revealed that 71.4% of students controlled their weight by doing regular exercises (55.0%) and controlling overeating (45%). Parents often applied healthy cooking methods (89.3%) and low calorie menus (64.3%), which they learned from nutrition education. Most parents perceived that the weight control program was helpful for their children (89.3%) and themselves (92.9%) as well.

This study was conducted to investigate instant coffee-mix intakes and its relations with anthropometric measurements, nutrient intake, and blood lipid in Gangneung and Samcheok residents. Coffee-mix is a mixture of instant coffee, sugar and coffee-creamer. It is a standardized convenience food in Korea. Recently, Koreans appear to consume too much of instant coffee-mix. The respondents of this study were 218 Koreans (Gangneung region 133, Samcheok region 85). The average age was 56.0 years (male), 57.5 years (female). They were divided into 2 groups, the instant coffee-mix drinkers and the non-drinkers. The nutrient intake and anthropometric measurements and their relations with coffee-mix intakes were analyzed (nutrient intakes were calculated by converting per 1,000 kcal and adjusted by age, region). As for male, body fat was significantly higher in coffee-mix drinkers (18.1 kg, 25.0%) than in non-drinkers (17.1 kg, 23.8%). In the case of females, serum triglyceride was significantly higher in coffee-mix drinkers (109.1 mg/dL) than in nondrinkers (102.9 mg/dL). Coffee-mix intakes and coffee-mix's contributions to energy were higher for participants from Samcheok (21.2 g, 4.7%) than those from Gangneung (16.6 g, 3.4%). In addition, for Samcheok, coffee-mix's contribution to energy was significantly higher in male (5.6%) than in female (4.2%). Coffee-mix intakes and energy contribution of coffee-mix were not significantly correlated with anthropometric measurements. Only HDL-cholestrol showed significantly negative correlation with coffee-mix's contributions to energy. Based on the above results, we conclude that usual instant coffee-mix intake may increase intakes of sugar and fat and exert negative effects on serum lipids. Therefore, it is needed to control too much instant coffee-mix intake in the dietary management of rural residents.

Eating breakfast provides crucial nutrition for brain function and helps promote overall health. It is especially critical in growing adolescents, as it is known to form good eating habits and better study habits. This study investigated the effects of skipping breakfast on nutritional state, fatigue level, and attention level. A cross-sectional study was conducted in 2010 on total of 828 adolescents composed of 414 boys and 414 girls. Students who ate breakfast never to twice per week were placed in the breakfast-skipper group while students who ate breakfast more than five times per week were included in the breakfast-eater group. Students performed a self-reported questionnaire on food behaviors, amount of food consumption, fatigue level, attention deficient hyperactivity disease (ADHD) level by Conners-Wells' Adolescent Self-Report Scales, depression scale, and self-esteem level. Statistical analysis was conducted using the SAS program (version 9.1). A total of 135 boys (32.6%) and 138 girls (33.3%) were included in the breakfast-skipper group, whereas 241 boys (58.2%) and 223 girls (53.9%) were included in the breakfast-eater group. The breakfast-skipper group showed irregular food behaviors and lacked nutrients. Specifically, energy (p< .001), protein (p< .001), dietary fiber (p< .001), calcium (p< .01), vitamin A (p< .01), thiamin (p< .05), niacin (p< .001) levels in boy breakfast-skippers were statistically lower compared to boy breakfast-eaters. Intakes of all nutrients except fat in girl breakfast-skippers were statistically lower than in girl breakfast-eaters. Girl breakfast-skippers (41.3%) showed significantly higher fatigue risks compared to girl breakfast-eaters (21.5%). Low attention level was also observed only in girls in the breakfast-skipping group. Moreover, students in the breakfast-skipper group showed higher scores for depression and low self-esteem (p< .001). In conclusion, skipping breakfast has effects on young adolescents' nutrition, manifesting as high fatigue level and low attention level, especially in girls.
