The present study was designed to observe whether nutritional education on children or mothers of the children who avoid to eat vegetables can improve the preferences for the vegetables of the subjects. The subjects were 45 children who are fourth to sixth grade of primary school in Bibong. They were assigned to one of three groups which are Control, Children Education and Mothers Education groups. Control group was not given any special education, while experimental groups were given nutritional education for 4 weeks. The effects of education was evaluated in the aspects of preference changes for vegetables, nutritional knowledge, attitude and food behavior of the subjects The results are summarized as follows. 1. Preferences to cucumber, lettuce, chinese cabbage and raddish were high in three groups while greenonion, onion, lotus roots and red pepper didn't suit for their taste. 2. Significantly increased scores for the preference to red pepper, pumpkin, Dorajee(root of chinese bell-flower), braken, mushroom was shown only in the children who had nutritional education while the children in the group of Mothers Education improved their preference only cabbage and lotus roots. 3. Nutritional knowledge of the children in Children Education group has improved significantly(p<0.05). While there was no significant difference between control and Mothers Education group. 4. When scores for food habit of mother and children were estimated, there was no significant difference among three groups. However, score of food habit in children was higher than that of mothers. 5. Food habit and nutrition knowledge of mother were not well corelated with dietary attitude and behavior of their children. These results indicate that the program of nutrition education in the present study can improve the food choice of children for vegetable and correct one-sided food habit. The program applied in this study would serve a kind of model for the dietetic teachers to guide the children who mainly dislikes vegetables.

This study evaluated on the recognition and satisfaction for functional bakery products by consumers living in Seoul, Overall, 82.0% answered of the respondents reported that they had 'yes' which was 4.5 times as much as those who answered 'no' tried functional bakery products. Purchasing mostly depended on 'myself' (69.0%), and other methods of acquiring information as well as 'bakery' (10.8%), 'neighbour' (8.5%), 'media' (7.9%), and the 'internet' (3.7%). The preferred functional ingredients were 'sweet potato' with (22.9%), and 'rye and oat' (13.8%), 'green tea' (13.5%), 'pumpkin' (11.4%), and 'chestnut' (7.3%) were other preferred ingredients. The reasons for this preference were that they were 'healthy' by (47.1%) and had a 'good taste' by (36.6%). Evaluation of the recognition of functional bakery products revealed that, 'nutrition' had the highest scale of recognition of (3.80 out of 5), and followed by 'healthy' with (3.69 out of 5). Conversely, 'proper price' received a below average score of 2.97, indicating dissatisfaction. Moreover, the overall average satisfaction with functional bakery products was 3.37, and with the taste, nutrition, and quality receiving a highly satisfactory score of 3.52, and price receiving an unsatisfactory score of 3.00. The factors most important to improve functional bakery products were, 'variety' (37.6%) was most important, followed by 'increased nutrition' (21.2%) and 'lower price' needed to be improved as well. The factor that had the greatest influence on the decision to purchase functional bakery products was 'material' with (3.737) followed by 'name value' with (3.56).

This study examined the relationship between chlorophyll(Chl) and ascorbic acid(ASA) as an index of freshness for vegetables, when the general consumers purchase several kinds of vegetables at the market. The leaves and fruits of several types of vegetables were divided into top, middle, and basal sections. Chl was determined by a spectrophotometer, and ASA was analyzed by high-performance liquid chromatography. For the vegetable sections, we found that Chl and ASA levels were highest in the top sections, followed by the middle, and were lowest in the basal portions. For the relationship between Chl and ASA in vegetables, there were seven classifications including high Chl(above 80mg/100g of fresh weight) and high ASA(above 80 mg/100 g of fresh weight) for mallow, and kail; the second group had high Chl and low ASA(below 80 mg), such as in spinach, burdock, and perilla leaves; the third group contained medium Chl($40{\sim}80mg$) and medium ASA($40{\sim}80mg$) levels, such as for gonddalbee, angelica, pumpkin leaf and coriander; the fourth group had medium Chl and low ASA levels, as in crown daisy and lettuce; the fifth group contained low Chl(below 40 mg) and high ASA, such as in hot peppers and parsley; the sixth group had low Chl and medium ASA levels, and included broccoli, pak choi, and sweet peppers; finally the seventh group contained low Chl and low ASA levels, as in dropwort, young radishes, shallots, cucumbers and swiss chard.

This study investigated the antioxidative activities and quality characteristics of gruel as a home meal replacement with Angelica keiskei powder pre-treated by far-infrared radiation or freeze-drying methods. Far-infrared treated Angelica keiskei powder (F-IAP) showed significantly lighter, weaker green, and stronger yellow color values than powder subjected to freezedrying (FAP) (p<0.001). F-IAP showed higher total phenolic compound contents than that of the FAP. ABTS radical scavenging activity of F-IAP was 50.31%, which was significantly higher than that of FAP, at 43.51% (p<0.05). Color values of gruel significantly decreased with increased addition of Angelica keiskei powder (p<0.05). Gruels containing far-infrared treated Angelica keiskei powder (F-IAG) showed higher total phenolic compound contents as well as ABTS radical scavenging activities compared to the gruels containing freeze-dried Angelica keiskei powder (FAG). Gruels containing 5 g of Angelica keiskei powder showed 2.0 to 2.5 times higher antioxidant activities than those containing powder alone due to the presence of other ingredients with antioxidant activities such as black soybean or sweet pumpkin. In the results of sensory evaluation, F-IAG containing more than 5 g of Angelica keiskei powder had higher sweetness and roasted grain flavor, as well as lower bitterness and astringency compared to FAG. Sensory acceptance tests of all samples showed higher scores than 5.0 representing possibilities of successful development of gruels as a home meal replacement containing Angelica keiskei powder.

Objectives: The purpose of this study is to categorize farm types and analyze the cultivated area and labor input time for each crop over a year in order to decide farm type conducting for the hazard exposure assessment. Methods: Crops ranked within the top 45 by cultivated area in Korea were selected and 15 target crops that exposure assessment had been conducted for through the Rural Development Administration(RDA) pilot research projects were selected. Labor input time was based on data investigated through RDA research surveillance. If there was no data, data from Statistics Korea was used. Data from Statistics Korea was used for total cultivated area. Results: Crops were divided into 5 types: open field crops(Chinese cabbage, Corn, Ginger, Potato), fruits (Mandarin, Pear), green house crops(Cucumber, Lily, Oriental melon, Pumpkin, Tomato), livestock(Poultry), specialty crops(Ginseng, Oyster mushroom, Tobacco). The cultivated area for potato was the largest, and lily was the smallest among the crops. Labor input time over a year was the highest with oyster mushroom and the lowest with pear. Total labor input time by crops was the highest with mandarin and the lowest with Chinese cabbage. Conclusions: To evaluate hazard factors of farm work, it's essential that crops and tasks be classified based on the size of farmers and working hours by farm type. Therefore, the priority of management should be determined based on the cultivated area and total labor time, but the characteristics of tasks in each crop should also be considered.
