The purpose of this study is to investigate how fifth and sixth graders recognize average and to find out suggestions for teaching/learning methods of average by examining which difference there is depending on the way of the word problem presentation. For the this purpose, was conducted experiment study with the way of the world problem presentation set up as experimental treatment. The conclusions drawn from the results obtained in the this study were as follows : First, since students who did not learn the regular course of average had various informal concepts already, it is needed to consider handling more various concepts of average in order to enable students to expand flexible thoughts. Second, compared with fifth and sixth graders showed a wide difference in informal concepts of average depending on the way of the word problem presentation. In expect data with given average, concepts of mean as algorithm, balance point, and mode indicated similar percentage, while in estimate average with given data, the percentage of students who showed the concept of mean was very high at 67.6%. That may be because problems related to mean in the current textbooks are items of 'estimate average with given data', so in types of 'estimate average with given data', students solve questions with mean as algorithm without considering situations of problems. This result suggests that it is necessary to diversify the way of the word problem presentation even in textbooks. Third, as a result of analyzing informal concepts of average, there was significant difference in grades. In addition, the results suggested that there would be difference in the concepts of average depending on gender or attributes of discrete quantity and continuous quantity.
This study was carried out to establish genetic understanding of three Sasang constitutions of Taeumin, Soeumin and Soyangin by Random Amplified Polymorphic DNA(RAPD) analysis. We have applied RAPD analysis to pooled DNA sample as a means to achieve rapid screening of large numbers of primers for their capacity to reveal constitutions-specific polymorphisms. From an initial 440 primers, 13 polymorphic primers between different constitutions were selected. Bandsharing(BS) and mean average percentage difference(MAPD) calculated within and between three constitutions using RAPD fingerprint data showed a higher degree of homogenity within than between the constitutions and indicated measurable divergence between three constitutions. The RAPD bandsharing(BS) values ranged from 0.71 to 0.73 between the three constitutions. The interconstitution divergence was narrower between Taeumin and Soeumin, than between the other paired constitution comparisons. The genetic distance between the three constitutions was measured by BS values. Genetic distance by RAPD analysis was 0.007 between Taeumin and Soeumin, and 0.014 between Soyang and the others. In conclusion, the genetic distance of Teaumin and Soumin was closer than that of Soyangin in the analysis of RAPD by using 440 primers.
Purpose: Many techniques have been described for achieving vertical augmentation of the maxillary sinus. The aim of this study is to evaluate the effect of low-intensity pulsed ultrasound (LIPUS) to enhance bone regeneration after sinus floor elevation. Methods: The sinus lifting technique was performed through a lateral approach on 8 different sites of 5 patients (3 males and 2 females) and their mean age was 45.7 years old. The sites were randomly assigned to the control or test groups. The control group had 4 sites that received lateral sinus lifting procedure only, while the test group had 4 sites that received LIPUS application after the lateral sinus lifting procedure. 24-32 weeks (an average of 29 weeks) postoperatively, new bone formation in the augmented sinus sites was evaluated through histologic and histomorphometric analyses of the biopsy specimens obtained during implant placement. Results: In the test group, the mean percentage of newly formed bone was $19.0{\pm}2.8$%. In the control group, the mean percentage of newly formed bone was $15.2{\pm}3.1$%. The percentage of newly formed bone was approximately 4% higher in those cases where the sinus was treated by LIPUS than the percentage in those cases where it was not used. The difference was statistically significant. Conclusions: Within the scope of this study, low-intensity pulsed ultrasound application after sinus lifting appeared to have a significant effect on the development of new bone formation.
Food neophobia, unwillingness to try novel foods, is a personality trait that can influence children's food preferences and consequently their food acceptance and consumption. The purpose of this study was to determine whether children with food neophobia have poor dietary and growth outcomes compared to non-neophobic children. Subjects were 332 primary school children from 6 randomly selected schools in the district of Hulu Selangor, Selangor. Parents and children were interviewed to obtain demographic, socio-economic, food neophobia and dietary intake information. The children were also measured for weights and heights. One-way ANOVA and Chi-square procedures were utilized for statistical data analysis. Children with food neophobia had higher intakes of energy and most nutrients than average and neophilic children. However, only the mean intakes of protein (p < 0.05) , fat (p < 0.05), vitamin A (p < 0.01) and iron (p < 0.01) were significantly higher in neophobic than average or neophilic children. Compared to neophilic and average groups, a higher percentage of neophobic children met 2/3 of the RNIs for energy $(85.2\%)$, protein $(98.4\%)$ and vitamin A $(72.1\%)$. Mean percentage of carbohydrate energy was lowest$(54.8\pm6.6\%)$ while fat energy $(31.8\pm6.2\%)$ was highest among neophobic children. Neophobic group had the lowest percentage of children $(49.2\%)$ with carbohydrate energy > $55\%$ but highest percentage $(50.8\%)$ with fat energy > $30\%$. For the three study groups, the mean number of servings for all food groups, except grain and cereal, did not meet the Food Pyramid recommendations. Neophobic children consumed significantly more numbers of servings from the meat group than average and neophilic groups (p < 0.01). All study groups had relatively low mean dietary diversity scores but neophobic children had the lowest score $(0.67\pm0.73)$ compared to the average $(0.97\pm0.72)$ and neophilic $(1.98\pm0.81)$ groups. Significant difference in mean dietary diversity scores were only observed between neophobic and neophilic children (p<0.05). Higher percentages of neo-phobic children had low weight-for-height and were at-risk of overweight(p < 0.05). Nutrition practitioners need to understand children's food preferences in their efforts to promote healthful diets for children. To improve children's eating behaviors, parents may need the guidance and support from nutritionists and dietitians that are specific to their needs and their child's situation.

The level of ${\beta}-glucan$ which is a major soluble dietary fiber found in the grain endosperm cell wall was highly variable among 25 barley genotypes grown at four locations including Suwon, Naju, Jinju, and Jeju. Statistically significant genotypic effects were observed for ${\beta}-glucan$ content at each or across growing sites (P<0.001). On average, 'Chalssalbori' showed the lowest percentage ${\beta}-glucan$ (4.04%) among genotypes in the grain, whereas 'Yonezawa Mochi' was highest in percentage ${\beta}-glucan$ (6.46%) compared to other genotypes. The significant difference between genotypes was approximately 1-2% across environments. The effects of location or interaction between locations and genotypes were not significant on the variation of ${\beta}-glucan$ contents. High ${\beta}-glucan$ content seemed to be greatly associated with such grain traits as waxiness and presence of husk except for 'Chalssalbori'. The waxy genotypes had a mean of 5.37% and values ranging from 5.28 to 5.47%, but normal genotypes had a mean of 4.78% and values ranging from 4.69 to 4.88% over environments. Hulless barley genotypes were also higher than hulled barley genotypes for the average ${\beta}-glucan$ content in both individual and over all environments. The difference between the hulled and hulless gene pools was on average of 0.37% with ranges from 0.19% to 0.56% at four environments. ${\beta}-glucan$ content measured from a mapping population of $F_5$-derived 107 lines derived from the cross between 'Yonezawa Mochi' and 'Neulssalbori' was not significantly associated with other agronomic traits except for 1,000-kernel weight at the '01 Suwon environment. Not too much information on the relationship of ${\beta}-glucan$ content to agronomic traits was available.
Randomly Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) analysis was carried out with a battery of 11 random decamer primers to study band frequency (BF), genetic identity index (I) and mean average percentage difference (MAPD) between Bhadawari and Murrah breeds of buffalo. The primers OPA04 and BG15 resolved a band of 460 bp, which was present only in animals of Bhadawari breed. Whereas, the primers OPA14, BG27 and BG28 produced Murrah specific fragments of sizes 730 bp and 1,230 bp, respectively. The estimate of genetic identity index was highest (0.845) with the primer OPA01 and the lowest (0.479) with the primer BG27. The genetic identity index pooled over the primers was 0.596${\pm}$0.037 between these two breeds. The highest MAPD estimate (53.9) between the two breeds was obtained with the primer BG27 and the lowest (14.3) with the primer OPA01. It might be concluded that the genetic identity index between these two breeds calculated on the basis of BF showed moderate level of genetic identity with the primers employed. MAPD calculated on the basis of uncommon bands also demonstrated lower to medium level of genetic difference between Bhadawari and Murrah breeds of buffalo.
Objectives : The purpose of this study was investigation of quality and quantity of nutritional intake related oral health status among Korean elders. Methods : The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference Intakes For Koreans(KDRIs). Chi-square test for Complex Samples was used to determine the relationship between oral health and inadequate nutrient intake in Korean elders. The complex samples general linear model was used to test difference of average value difference of nutrient intake percentage compared to dietary reference intake(DRI), energy intake rate from three major nutrients, average mean adequacy ratio(MAR) and index of nutritional quality(INQ) related oral health status. Age, sex and total energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results : We could found the difference of the nutrient intake and the dietary quality related oral health status among Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energy intake rate from three major nutrient was lower as oral health status became worse. The percentage of subjects with nutritional intakes under showed highest level in worst oral health status. As oral health status became worse, average mean adequacy ratio(MAR) was lower and the number of nutrient of which index of nutritional quality(INQ) was under 1 was more. Conclusions : From the result above, this study clearly shows the level of oral health affecting the inequalities of eating and the food for the people. And the various propose of oral health policies is needed for vulnerable groups who needs solution to solve the problem of inequality of food distribution where intensive distribution of nutrition problem occurred. Sufficient, safe, and a variety of healthy food intake is a fundamental right of our people. And also, to apply this policy in reality, institutional arrangements and organizations, and specific performing system will be needed.
To investigate the correlation between college women's energy intake and body fat percentage, this study was undertaken with 116 college women aged 19-24 years. The subjects were 20.9 years old on the average, and mean height and weight was 161.3 cm, 51.2 kg. Blood pressures were 112.4 mm Hg(systolic pressure), 70.2 mmHg(diastolic pressure). The number of pulse was 75.5 count/min. The energy intake and percent body fat were examined. The average intake of energy was 7652kcal/day(82.3% of RDA), which was lower than the recommended amount. It was similar to the level of energy intake of Korean women. BMI was 19.7 and body fat percent was 24.4%, so they appeared plump. According to BMI, 43.1% of subjects was grouped into normal, 56.9% was thin ; there was no difference between groups in age and stature. Also, normal group(27.1%) shoed significantly higher body fat percent(27.1%) than thin group(22.3%). But, body fat percent of thin group according to BMI was shown normal. Therefore, it may be thought that BMI is unsuitable indicator in this study. As a result of analyzing the correlation between body-measuring value and food intake, body fat percent against body weight and BMI was significant at the level p<0.001, but thee was no significant correlation with food intake. Therefore, it is desirable to recommend a healthful dietary lifestyle and activities for young women who want to reduce body weight due to excessive concerns regarding their outward figure.
