The nutritional status of pre-school children is important for both physical growth and functional development. This study investigated the anthropometric, nutrient intakes and dietary quality of the pre-school children living in Asan for planning nutritional education program. The dietary intakes were measured by 2-day 24 hr recall recorded by children's mothers and the anthropometric data were collected by measuring children's weights, heights, and percent body fat at Asan Public Health Center. The children were 161 boys and 129 girls aged 5 and 6 years. When children's nutritional status was determined by their anthropometric status (underweight, normal weight and overweight) determined by z-score (normal range between -1.00 and 1.00), only 1.4% of the children belonged to underweight group while 55.7% and 42.9% belonged to normal and overweight groups, respectively. Significantly higher number of children belonged to overweight group for 5 year-olds. No differences were observed in nutrient intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) values among nutritional status groups. Intakes of the most nutrients were adequate, but NAR and INQ of calcium and zinc were low. When nutrient intakes, NAR and INQ were compared by sex or age, all nutrient intakes were appropriate except calcium and zinc intakes of 6 year-olds. Nutrient intakes of 5 years were higher than those of 6 years. The mean of nutrient adequacy ratio (MAR) was 0.85 and mean INQ was 1.51 for all participants. The nutritional management program for pre-school children in Asan would be directed differently by age groups and education material should contain contents educating to consume moderate amount of food for 5 year-olds and to increase intake of foods with mineral nutrients such as calcium and zinc for 6 year-olds.

This study was conducted to derive optimal design floods by Generalized Extreme Value (GEV) distribution for the annual maximum series at ten watersheds along Han, Nagdong, Geum, Yeongsan and Seomjin river systems. Adequacy for the analysis of flood data used in this study was established by the tests of Independence, Homogeneity, detection of Outliers. L-coefficient of variation, L-skewness and L-kurtosis were calculated by L-moment ratio respectively. Parameters were estimated by the Methods of Moments and L-Moments. Design floods obtained by Methods of Moments and L-Moments using different methods for plotting positions in GEV distribution were compared by the Relative Mean Errors(RME) and Relative Absolute Errors(RAE). The results were analyzed and summarized as follows. 1. Adequacy for the analysis of flood data was acknowledged by the tests of Independence, Homogeneity and detection of Outliers. 2. GEV distribution used in this study was found to be more suitable one than Pearson type 3 distribution by the goodness of fit test using Kolmogorov-Smirnov test and L-Moment ratios diagram in the applied watersheds. 3. Parameters for GEV distribution were estimated using Methods of Moments and L-Moments. 4. Design floods were calculated by Methods of Moments and L-Moments in GEV distribution. 5. It was found that design floods derived by the method of L-Moments using Weibull plotting position formula in GEV distribution are much closer to those of the observed data in comparison with those obtained by method of moments using different formulas for plotting positions from the viewpoint of Relative Mean Errors and Relative Absolute Errors.

The prevalence of obesity is continuing to increase. Self-perceived body image among women has drawn a lot of attention in Korea due to unhealthy weight control trials. This study was conducted to determine the relationship between self-perceived body image and dietary intakes among Korean women. For the analysis, 1,747 subjects were selected after eliminating those who were likely to have recently altered their diet based on the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data. The subjects were divided into three groups: underweight, normal, and obese groups according to their perception of body image. Daily nutrient intakes, NAR (Nutrient Adequacy Ratio), and food intake frequency were assessed according to age group and body image perception. Only energy intake showed differences among the three body image perception groups across all age groups, but not statistical differences. Analysis of NAR and the order of most frequently consumed food items confirmed these findings. The ratio of underweight women that perceived their body size as normal or overweight was higher with younger age. Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. This study confirmed that nutritional knowledge is important for healthy weight control trials. Nutritional education for healthy dieting should be emphasized among Korean women.

It has been a long tradition in the field of nutrition that the degree of malnutrition in a community used to be estimated by the degree of the adequacy of nutrients consumption in the households. The adequacy of nutrient consumption in the households then used to be applied to estimate the degree of malnutrition of the children. Such a practice is theoretically acceptable in the community where the food sharing within the household is individual serving style such as in European countries. However, the community where the dietary habit in the household is communal such as in Korea, the estimation of single serving portion from household consumption is quite uncertain. Because of such an uncertainty this study is intended to test the validity of the household food consumption level as an indication of nutritional status of the children in the rural farm households in Korea. The date from the household consumption survey in 1982 by the Korean Rural Nutrition Institute has been used for the analysis of food consumption levels of the households. The survey on the nutritional status of children of 127 preschool children from 78 farm households, has been conducted during May 1983. The nutritional status of the children has been directly measured by weight, height, skinfold thickness, haemoglobin, haematocrit and morbidity of influenza and diarrhoea. The analysis has been conducted to distinguish the differences in prevalence of malnutrition of children from the estimated of household consumption and that of from the direct measurement of nutritional status of children. The results show that the degree of malnutrition of the estimated by the household consumption level has not related with the prevalence of malnutrition by the direct measures of nutritional status of the children. Therefore, the validity of household consumption level as an indication of nutrional status in a same household is quite uncertain for the population studied.
The purpose of this study was to set new guidelines for adenosine triphosphate (ATP) bioluminescence hygiene monitoring of distribution trays at children's foodservices. Five dietitians visited 223 foodservices (95 institutional, 128 small) to examine whether they adhered to the norms of 'Keeping distribution tray sanitary by washing/sanitizing' and 'Performing food distribution in a clean and appropriate way'. In this visit, dietitians swabbed 100 ㎠ area of the distribution trays twice, once for obtaining ATP measurements and the second time for Aerobic Plate Counts (APC) using 3M Petrifilm Plates. Chi-square test and ANOVA were applied using SPSS 23.0 software. SPSS 23.0 was used to conduct graphical and statistical analysis of the raw data of ATP measurements, which were further transformed by a Box-Cox transformation. The mean of APC from all the subjects inspected was 3.8×102±2,102.0 CFU/100 ㎠. A total of 208 (93.3%) trays were observed within the acceptable limits of APC (Pass<5.0×102 CFU/100 ㎠). APCs taken at institutional foodservices showed significantly lower levels (1.4×102±600.0 CFU/100 ㎠, P<0.01) compared to the small foodservices (5.5×102±2,718.7 CFU/100 ㎠). No significant differences were observed between the two groups in ATP measurements and in the performance rate of 2 checklist items. As against the 93.3% APC adequacy from the total subjected inspection, total ATP adequacy (Pass≤300 RLU/100 ㎠) was only 71.7%. Therefore, more practical guidelines should be prepared for the assessment of the hygiene of distribution trays. In the graphical and statistical analysis, levels below 250 RLU/100 ㎠ was considered 'Pass', while equal to or greater than 350 RLU/100 ㎠ was considered 'Fail' for distribution trays.

In this study, the experimental and analytical study were performed on the location of longitudinal cracks in the middle of underground box structures. The location where the longitudinal cracking occurred was investigated that the overlapping joint of the rebar and the section of maximum tensile stress generated. Using the finite element analysis, the strength reduction ratio of the rebar was estimated by lack of overlap joint length. As the result of adequacy investigation for the length of the overlap joint presented in the design criteria, it was analytically proved that the lack of the overlap joint length could be cause the decreasing cross-sectional force and concrete cracking. As the result of this study, the adequacy of the overlapping criterion in the current design criteria was confirmed based on the finite element analysis and actual field case. In the case of overlapping joints installed in inappropriate position, it was considered that a long term crack control would be need to ensure the sufficient safety factor for the designed cross-sectional force.
The purpose of this study was to investigate effects of the developed nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at a community health center. Developed the nutrition education program, four weeks' nutrition education including provided twice individual meal as diet therapy (2 hour/lesson/week, 4 week), was provided to 20 diabetic elderly (12 male, 8 female, 50-75 yrs): 1st lesson "Introduction: management of diabetes mellitus", 2nd lesson "6 Food groups and sources of 6 food groups", 3rd lesson "Individual daily energy requirements and food exchange units", and 4th lesson "Food choice for diabetes mellitus". For effects' analysis of the developed program, we assessed the changes in anthropometric characteristics; biochemical characteristics and nutrient intakes using 24 hr recall method. Effects of the developed nutrition education program were as follows: weight was significantly decreased, blood urea nitrogen (BUN) and glycosylated hemoglobin (HbA1c) were significantly decreased, and distribution of subjects in BUN and HbA1c was significantly changed. In protein : fat : carbohydrate (PFC) ratio, it was significantly changed from 15.98 : 16.30 : 66.69 to 17.51 : 18.94 : 64.10. In evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), protein, fiber, fat, vitamin E, niacin, folic acid, calcium and zinc were shown significantly positive changes in distribution of subjects according to intake level. The index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased. In conclusion, the developed 4 weeks' nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at community health center may improve the symptom of diabetes mellitus.

The study is to develop and present a leggings pattern that is suitable for the human body by using a standard body type avatar for a female in her 30s. As a research method, the average body type was selected from adult women in their 30s, and the appearance was evaluated using the CLO software program. The data analysis of this study compared the dimensions and shape of each part by legging. The leggings pattern suggested based on the above research results was determine to be a total length of 80.6cm and hip length of 24cm, and the knee length was set by dividing the legging in half from the waist to the hem and then adding 5cm. These figures were evaluated higher than Company D in terms of the adequacy of the upper part of the front and rear plates of Company A as well as the adequacy of the knee lines. Company A's figures were applied and corrected. For the front plate, the waist circumference was divided by 4, and 3.5cm was removed, and the hip circumference was set by dividing the hip circumference by 4, and 3.8cm was removed. In the appearance evaluation results Company D was highly evaluated in the suitability evaluation of the waist and hips, and the waist and hips were set using the pattern of Company D. The length of the front panel was modified by dividing the hip circumference by 4 and adding 1.8cm to the length, and the length of the back panel was modified by dividing the hip circumference by 3 and adding 8cm after dividing the hip circumference by 0.8cm.
Consumers differ with respect to the level of green attitudes and green purchase behavious and different consumer would have different perceptions on green market environment. This study attempted to explain how consumers perceive green market environment differently across different consumer groups in attitude-behaviour dimension in green consumption. After identifying the four consumer groups based on their attitude toward green purchase and green purchase behaviours, a multinomial logistic analysis and a stepwise discriminant analysis were conducted. This study found that reliability in green market was the most critical factor that contributes to enlarge positive green consumers. Also, the role of reference persons and adequate price of green products were also found to be important to stimulate green buying. By understanding the different role of those factors in each group of consumers, this study provided group-specific implications to expand green consumers.
