PURPOSE: The aim of this study was to explore the relationship of ready-to-eat cereal (RTEC) consumption with nutrition and health status. Examination of health status for this project included obesity, abdominal obesity, hypertension, hypertriglyceridemia, hypercholesterolemia, low-HDL-cholesterolemia, diabetes, anemia, and metabolic syndrome. METHODS: Two groups, RTEC consumers and those who did not consume RTEC, were identified using 24-hour dietary recall data from the 2012 Korea National Health and Nutrition Examination Survey (KNHANES). Nutritional intakes and risk factors of the two groups were compared using covariates-adjusted statistical procedures. Statistical analyses were performed using SAS survey procedures, and strata, cluster, and weight were considered. Subjects of analysis of nutritional intake were between the ages of 1 and 75, and those considered in the risk factor analysis were between the ages of 19 and 75. RESULTS: Results showed that 3.8% of the Korean population was RTEC consumers. Compared to the subjects who did not intake RTEC, RTEC consumers exhibited significantly higher intakes of calcium, thiamin, riboflavin, and vitamin C. It was also discovered that the percentage of people whose intakes were less than EAR decreased with RTEC consumption. RTEC consumption showed significant association with decreased systolic blood pressure, diastolic blood pressure, serum triglyceride, and serum total cholesterol. Consequently, prevalence of hypertension among RTEC consumers was significantly lower than that among non-consumers, and the odds ratio for hypertension was 0.19 after adjusting the models for covariates. CONCLUSION: Results of this study clearly suggest an association of RTEC consumption with improved nutritional status and cardiometabolic risk profile in Korean adults. Conduct of additional studies will be necessary in order to determine the nature of these relationships.

Dietary Variety Score (DVS) or Nutrient Adequacy Ratio (NAR) offers a way of comparing eating habits across populations and across countries. This study compared nutrients intakes, food intakes, DVS, and NAR between Korean and US adults using the large national survey data. 4662 Korean adults (men: 2201, women: 2461) aged 20 - 49 years were selected from the 'Korean National Health and Nutrition Survey, 2001' and 4199 US adults (men: 2127, women: 2072) aged 20 - 49 years were selected from the 'US National Health and Nutrition Examination Survey (NHANES IV, 1999 - 2002)'. The total plant food intakes were high in Korean adults, but the total animal food intakes were high in US adults. Intakes of legumes and nuts, vegetables and mushrooms were higher in Korean than in US adults. On the other hand, intakes of meats, milk and dairy products of US adults were higher than Korean. Beverage intakes were 8 - 10 times higher in US adults than in Korean. The mean DVS of Korean men and women were higher than US men and women. Intakes of fat, calcium and vitamin B2 of US adults were 1.5 - 2 times higher than those of Korean, which could probably related to larger consumption by US adults on milk and dairy product. While the intakes of carbohydrate and vitamin C of the Korean were higher than the US adults, which could presumably related to higher grain and vegetable consumption. Percent energy intakes from carbohydrate, protein, and fat were 64.1%, 15.8%, and 20.1% for Korean men, 52.4%, 15.0%, and 32.6% for US men, 65.9%, 14.9%, 19.2% for Korean women, and 52.1%, 14.7%, 33.2% for US women respectively, which showed higher %energy from carbohydrate in Korean and higher %energy from fat in US adults. Most nutrient intakes except energy and vitamin C expressed as %RDA were higher in US than in Korean adults. Mean Adequacy Ratio (MAR) of US men and Korean men were both 0.85, while the MAR was 0.81 for Korean women, 0.79 for US women. The Korean women's diet showed more diverse and adequate than the US women's diet.

The purpose of this study was to establish an association between the consumption of ready-to-eat cereal (RTEC), milk, and calcium within the context of the most current population dietary practice in Korea. Inadequate calcium intake among Korean children and adults is one of the important public health concern. Milk is one of the best calcium sources because of its bioavailability, and RTEC is one of the foods commonly consumed with milk. The most recent Korean National Health and Nutrition Survey, 2001 dataset was used as the source of data for this research. Subjects excluding pregnant women, were categorized according to gender and age (1~5, 6~11, 12~19, 20~49, 50 + years) and then by consumption of RTEC and milk. SAS and SUDAAN were used for statistical analyses. Sample weighted means, standard errors, and population percentages were calculated, and multiple regression model with adjustment for covariates were used to determine the predictability of total daily calcium intake from inclusion of RTEC and milk compared to the meal without RTEC and milk. RTEC was consumed by 2.4% of Korean people. Average calcium intake was 17 times greater when RTEC was consumed with milk than when RTEC was consumed without milk. Respondents who consumed RTEC with milk had significantly higher mean daily calcium and other nutrient intakes than respondents who consumed neither. In the multiple regression analysis, milk consumption with or without RTEC predicted total daily calcium intake after adjusting for age, income, and alcohol consumption (p < 0.0001). The percentage of respondents below the estimated average requirement (EAR) level for calcium was lower for RTEC consumers than for RTEC non-consumers in all age-gender groups, especially significant differences were in children aged 1~5, boys and girls aged 12~19, men aged 20~49, and women older than 50 years of age. RTEC consumption was not associated with intake in excess of the tolerable upper intake level (UL) for calcium. In conclusion, RTEC consumption was positively associated with both milk and calcium intakes in all age and gender groups in Korean population.

Since pathologic changes of exposed root surface inhibit cell attachment and new attachment of connective tissue have been made, many efforts were apply to change the exposed root surface condition. Scaling and root planing can not remove the endotoxin completely and forms the smear layer which prohibits the new attachment of connective tissue. Therefore, many kinds of chemicals were used for controlling the pathologic change of the root surface. The purposes of this study was to compare and observe the changes of the exposed root surface treated by scaling and root planning, Tetracycline HCl and Argon Laser. After the scaling and root planning of ten extracted premolars, the differences & the root surface among groups were observed under SEM. Control group showed smear layer and irregular amorphous surface. The dentinal tubule was not exposed. The debris and scale like texture were also observed. Tetracycline HCl treated group showed relatively smooth surface and the collagen fiber was observed in the dentinal tubule. Argon Laser treated group showed the most effective results under the conditions of 0.8 to 1.0w irradiation for 0.5 to 1.0 sec with pulse wave. The results of this study showed that the root surface change was associated with the intensity and the duration of Argon Laser irradiation. Further investigation for the surface change with the Argon Laser irradiation is recommended for understanding of clinical effect.

Gingival recession is exposure of the root surface with apical shift in the position of gingiva. The incidence of gingival recession is 8% in children and 100% after the age of 50. Recession tends to be found in patients with healthy gingiva, but more frequentely found in patients with periodontal disease, and it often causes mucogingival defects. Buccal surface of premolar is the area not only for severe gingival recession and cervical abrasion, but also the area of numbers of buccal frenum and less keratinized gingiva. Therefore, the goal of this study was to observe the patients with periodontitis and examine whether there are clinical relations between gingival recession and cervical abrasion of premolar and other factors related with the condition of periodontal health. Generally healthy 218 patients who had periodontal disease such as gingivitis and periodontitis, aged between 18 and 78, were examined for depth of periodontal poket, width of attached gingiva, gingival recession, cervical abrasion, and frenum of mid-buccal surface of premolar at the Department of Periodontics in Dankook University Dental Hospital and following is the result. 1.The average gingival recession and cervical abrasion of premolar with periodontal disease was 0.76mm and 0.29mm and each has 43% and 14% of incidence. Also the width of attached gingiva of mid-buccal surface was 1.77mm. The average periodontal pocket depth is 2.0mm and 47% of frenum were related. The frenum more frequently seen was narrow single shaped frenum, and the interdistance of the frenum was mostly over 4mm. 2.With statistical significance(P<0.05), the incidence of gingival recession increased with age and was related much more with female than male, the first premolar than the second premolar, and with narrow attached gingiva and frenum. 3.With statistical significance(P<0.05), the incidence of cervical abrasion increased with age and was related with the area of the first premolar and narrow attached gingiva, but the sexual and frenum differences were not statistically significant (P>0.05). 4.The severity of gingival recession increased with age and was more related with female than male, the first premolar than the second premolar. And the area of narrow attached gingiva and frenum showed more gingival recession and the distance of frenum was more highly related than shape, and they were statistically significant (P<0.05). 5. With statistical significance(P<0.05), the severity of cervical abrasion increase with age and was observed at the first premolar and narrow attached gingiva. But the sexual and frenum differences were not statistically significant (P>0.05).

Although noodles occupy an important place in the dietary lives of Americans, up until the present time research and in-depth data on the noodle consumption patterns of the US population have been very limited. Therefore, this study aimed to analyze the food consumption and diet patterns of noodle consumers and non-consumers according to age, gender, income, and ethnicity. The 2001-2002 NHANES databases were used. The NHANES 2001-2002 data showed that noodle consumers reporting noodle consumption in their 24-h recall were 2,035 individuals (23.3% of total subjects). According to the results, the mean noodle consumption was 304.1 g/day/person, with 334.3 g for males and 268.0 g for females. By age, the intake of those in the age range of 9-18 years old ranked highest at 353.0 g, followed by the order of 19-50 year-olds with 333.5 g, 51-70 year-olds with by 280.4 g, older than 71years old with 252.3 g, and 1-8 year-olds with 221.5 g. By gender, males consumed more noodles than females. Also, according to income, the intake amount for the middle-income level (PIR 1~1.85) of consumers was highest at 312.5 g. Noodle intake also showed different patterns by ethnicity in which the "other" ethnic group consumed the most noodles with 366.1 g, followed by, in order, Hispanics with 318.7 g, Whites with 298.6 g, and Blacks with 289.5 g. After comparing food consumption by dividing the subjects into noodle consumers and non-consumers, the former was more likely to consume milk, fish, citrus fruits, tomatoes, and alcoholic beverages while the latter preferred meat, poultry, bread, and non-alcohol beverages.

This study is verifying the hypothesis that distraction followed by recompression may promote fracture healing of the osteoporotic bone on the assumption that distraction induces increased callus formation at the distracted gap and recompression results in fusiform callus, having biomechanically stronger fracture stiffness. Sixty-six Sprague-Dawley rats, in which osteoporosis were induced 6-8 weeks after oophorectomy, were separated into two groups. Group I was control group that had fracture healing by simple external fixation. Group II was experimental group that had fracture healing by monofocal distraction-compression. Radiomorphometric study revealed that there was significantly increased amount of callus and ensuing bone formation, which becehe obvious from 20 days after osteotomy in group II compared with group I. Biomechanical study also showed that tensile break strength was significantly higher in group II compared with group I with time. It is concluded that monofocal distraction-compression method may be one of the useful method to promote fracture healing of the estrogen deficient osteoporotic bone.
