This study was designed to make an analysis of the content related with Korean traditional food culture covered in the section of Food and Nutrition of Home Economics textbooks based on the current 7th curriculum and to investigate the recognition and needs for education on Korean traditional food culture among high school students. Through this, we tried to present basic data contributing to the construction of practical educational content and educational method in relation to Korean traditional food culture. The results of this study are as follows. The content of Korean traditional food culture in the section of Food and Nutrition covered by Home Economics textbooks consisted of 'Setting the Table and Table Manners' for the third graders of middle school, 'Planning and Preparing Invitation and Events' for the freshman of high school, and 'Food Culture and Preparation of Food' for the second and third graders of high school. High school students were proud of themselves on Korean traditional food culture, but fail to apply their knowledge to real household life. In particular, it was proved they didn't understand' Korean Festival Holidays and Annual Customs: The need on the content of Korean traditional food culture showed significant difference in accordance with pride on traditional food culture, its succession in the families and one's recognition. And it was highly correlated with the subordinate variables such as demands, interest, utilization. These results showed that the education of Korean traditional food culture is an area that is demanded and how to cook Korean traditional food should be included in the content for education and practice of cooking and experience of food culture should be dealt with as the educational methods.

At harvest, the starch contents of apples, which were related to their maturity, were quantified by using image analysis. The stained area was measured by a computer vision system when an apple slice was stained with KI/I$_2$ solution. The stained area ratio of the stained area of the apple slice to its whole area, or the starch index, was defined as an indicator of starch content. When Tsugaru apples were manually sorted into immature, turning and mature groups, their starch indices were 0.374, 0.312 and 0.129, respectively. Meanwhile, the starch index had correlation to various physicochemical properties of Tsugaru apples. At the statistically significant level of 0.1 %, it was correlated with the pH value, bio-yield force, rupture force and color of intact and skin-removed apples. At the 1 ％ significant level, it had the correlation with the density and moisture content.

This research investigated the relative influence of culture contents from Korea, China, and Japan published in the internet version of local newspapers for Malaysia, Mongolia, Uzbekistan, and Spain (from January 2010 to December 2014) and from Singapore (January 2012 to December 2014) using content analysis focused on the frequency distribution of newspaper content. 'Food' showed the highest appearance frequency of the 11 culture contents investigated in the study. Among the articles related to Korea, 'Pop Music' showed the highest frequency for Malaysia, Uzbekistan, and Spain and 'Star' showed the highest frequency for Singapore and Mongolia. Among the Hallyu related contents, 'Pop Music' showed the highest frequency followed by 'Star', 'Movie', and 'Drama'. Articles related to Korea showed a significantly higher frequency than articles related to China and Japan in 'Pop Music' and 'Star' categories. Spain showed articles related to Korea only in the 'Pop Music' category.

The aim of this study was to investigate the relation of sensory quality traits of cooked beef to fresh meat quality and histochemical characteristics, especially muscle bundle traits, in the longissimus thoracis muscle of Hanwoo steers. Cooking loss negatively correlated with softness, initial tenderness, chewiness, rate of breakdown (RB), and amount of perceptible residue (AR) after chewing (p<0.05), and drip loss showed negative correlation with RB and AR (p<0.05). All the attributes of tenderness exhibited negative correlation with the Warner-Bratzler shear force value (p<0.05). Marbling score and the intramuscular fat (IMF) content showed positive correlation with all the organoleptic characteristics, including tenderness attributes, juiciness, and flavor (p<0.05). Regarding histochemical characteristics, muscle fiber size did not have a significant correlation with all the sensory quality traits, although the area percentage of type I fiber was related with softness, initial tenderness, and chewiness (p<0.05). On the contrary, the characteristics of muscle bundle were related to all the sensory tenderness attributes (p<0.05), and the sensory tenderness increased with smaller muscle bundle size (p<0.05). These results suggest that the IMF content and bundle characteristics can be used as indicators for explaining the variations in sensory tenderness in well-marbled beef.

The ethanol extraction yield of Meliae toosendan fructus(MT) was about 24.5% by extract apparatus. This study was done to investigate the carbohydrate metabolism related enzyme activities and antioxidative effects of MT in streptozotocin (STZ)-induced diabetic rats. The contents of serum glucose, triglyceride (TG) were significantly decreaed in MT treated group compared to the those of STZ-control group, also content of Total cholesterol was decreased. High density lipoprotein (HDL)-cholesterol was increased in MT treated group. The activity of glucose-6-pase(G-6-Pase) was significantly decreased in MT treated group. Also the activities of glucose-6-phosphate dehydrogenase(G-6-PDH) and glucokinase(Gk) were increaed in MT treated group. The content of hepatic glycogen was significantly increaed in MT treated group, in addition, content of malondialdehyde(MDA) was significanly decreased in MT treated group. Also, content of glutathione(GSH)was dereased in MT treated froup. whereas, activity of catalase(CAT) was significantly increaed in MT treated group compared to the those of STZ-control group. activity of glutathione peroxidase(GSH-Px) was inecreaed. In conclusion, these results indicated that ethanol extract of MT would have carbohydrate metabolism antioxidative effects in STZ-induced diabetic rats.

This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.

The purposes of this study were to: (a) identify the changes in food patterns for last 20 years; (b) analyze the factors affecting on the changes in food patterns; (c) investigate the impact of changes in food patterns on nutritional composition of the diet and diet-related health problems. A questionnaire was developed and mailed to 30 country members of the International Federation for Home Economics(IFHE) regional representatives. The response rate was 60%; simple descriptive and content analyses indicated that the significant differences of food consumption pattern were existed between western and eastern countries. Traditional food consumption patterns were maintained even though each countries' food consumption patterns have been dramatically changed due to the development of food technology and industrialization. The factors most frequently affecting on the changes in food patterns were nutrition and heallth-related educations. The food pattern changes have considerable effect on the nutritional composition of the diet among countries. The major diet-related health problems with nutrient deficiency were reported by underdeveloped countries such as India. In contrast to the above, in the developed countries, the adult disease related to the nutrition have been increased, while the developing countries such as Korea have the problems with nutrient deficiency and adult diseases simultaneously.

The objective of this study was to assess the reliability and validity of food security measures, which was developed based on the US household food security survey module (US HFSSM) with content validity in the Korean population. The reliability and validity were assessed by internal consistency, construct validity and criterion-related validity. The study included 446 households. Among those, 46.2% were households with children. The proportion of food insecure households was 33.3%. Among those, 35.4% and 64.6% households were food insecure with hunger and without hunger, respectively. The Cronbach's alpha coefficients were 0.84 and the infit value by the Rasch model analysis ranged from 0.68 to 1.43. The scale item response curves by food insecurity severity explained well the nature and characteristics of food security, indicating the highest proportion of "yes" for the items on diet quality, followed by those with diet quantity. The result of criterion-related validity showed that food insecurity status was significantly related in a dose-response manner with the household income level, food expenditure, subjective health state, subjects' educational level. Household food security status was also related to dietary diversity regarding protein foods, fruits and fruit juice, and milk and dairy product. These findings suggest that the food security instrument is reliable and valid and would be used to assess food security status in the Korean population.

This study attempted to evaluate the effectiveness of function of Wax Ground for obesity and the related disease of adult people can be developed by the combination of the 17 food materials screened in this study. The experiments using Sprague-Dawley male rats show that seventeen kinds of food material inhibited the increase of body weight gain, energy intake, fat pads weight, liver triglycerides content, atherogenic index, and blood glucose concentration induced by cafeteria diet. Oral administration of wax gourd decreased most body weight gain, energy intake, fat pads weight, and blood glucose concentration. Liver triglycerides content was the lowest in the group administered mulberry stem extract and the group administered pine leaves showed the lowest atherogenic index. The combined administration of wax gourd, mulberry stem extract and pine leaves improved more the obesity and related symptoms than the individual administrations.

In this study, evaluation on the loaches from the various sources was carried out in respect of their taste compounds. The samples were classified by local, season and growing condition and evaluated in terms of composition, the refuse, contents of nucleotides and their related compounds, total and free amino acid, organic acid and fatty acid. Evaluation on the compositions revealed the fact that, in terms of the local, the imported loach contain a low level of fat and high level of ash, in comparison with Korean loach; in terms of growing condition, cultured loach contains a high level of fat and low level of moisture, in comparison with wild loach; and in terms of the season, the summer loach contains less moisture than the fall loath; but as for the contents of other component, the summer loach was superior. As for the refuse, the imported loach had a greater refuse than the Korean loach. In the growing condition, the wild loach had lower value than the cultured loach. There was no substantial difference in each season. Also nucleotide and these related compounds were detected in all of the samples, while ATP was not found. The content levels of such detected compound did not show a substantial difference in each condition. However, generally, the imported loach was poor in such compound and all of the samples were high in IMP. The samples were high in total amino acids. The local and growing conditions showed no substantial difference, while in the season, the summer loach had a higher content of total and essential amino acid than the fall loach. As for the contents of free amino acids, similar distribution of the composition was shown in each sample, even though there was little difference in their constituents. Also, total content of free amino acid varied with the conditions of the samples. As for total content of organic acid and the distribution of the composition, there was a little difference between each condition. In the season and growing condition, the summer loach was high in organic acid. As for the distribution of the fatty acid compositions, there was no substantial difference between each condition and each sample. In the case of the wild loach, the summer loach was high in ${\omega}-3$ polyunsaturated fatty acid and the fall loach was high in essential fatty acid. Similarly, in the case of the imported loach, the summer loach was high in ${\omega}-3$ polyunsaturated fatty acid and the fall loach was high in essential fatty acid.
