Children's exposure to various vegetables has been associated with higher preferences and intake of vegetables. Attractive names have been reported to increase children's vegetable intake in school lunches. This study hypothesized that the number of vegetables identified correctly may be used as a measure of exposure to vegetables. The survey was administered to students (n=368) at an elementary school located in Gyeonggi-do to determine the association of number of vegetables identified correctly with factors regarding vegetable intakes and effects of descriptive menu names on consumption intentions in school lunches. Students were asked to identify the correct names for nine vegetables and rate their desire to eat six vegetable dishes labeled with general names and two different descriptive names. Descriptive menu names did not consistently increase subjects' desire to eat vegetables compared to general menu labels. Children who ate two vegetable dishes and more per meal tended to identify the names of more vegetables than those who ate less, without reaching statistical significance (P=0.057). Moreover, 5th graders who answered that they ate more than two vegetable dishes each meal had significantly higher scores in identifying vegetable names than those who did rarely (P<0.05). There was no significant association between the number of correctly identified vegetable names and children's vegetable preferences and frequency of being served vegetable dishes. Mother's vegetable preference showed a significant positive association with vegetable preferences of children (r=0.147, P<0.01) and fathers (r=0.340, P<0.01) as well as the number of correctly identified vegetables by children (r=0.183, P<0.01). The results of this study cannot support the advantage of descriptive menu labels over general menu labels. However, it suggests that the number of correctly identified vegetable names could serve as a measure of children's exposure to vegetables associated with factors regarding vegetable intake.

This study intended for Cheongryongsan Community Garden in Gwanak-gu, one of the demonstration places for 'Community Garden' Project recently implemented by the Seoul Government. This study had two major purposes: investigating the current status of the management and usage and identifying its characteristics; investigating users' awareness to consider the construction and operation directions of sustainable community gardens. This study was conducted based on several surveys such as an investigation into the spatial configuration and the management system of parks through a field study, a use survey through a questionnaire survey for vegetable garden users and an awareness survey about the construction direction of gardens direction preferred by users through the analytical hierarchy process (AHP). As a result of a questionnaire survey for vegetable garden users, the usage status was summarized as follows: Considering the common trends in the 2012 and the 2013 user survey, women used Cheongryongsan Vegetable Garden more than men. Over fifties used it most of all users. Users were mostly neighborhood residents. They used to visit there three to five times a week and stayed for about 30 minutes to one hour. Users differently responded to the question related to the order of priority for the use of the garden in the 2012 and the 2013 survey. They had increasingly used it for individuals' production activities more than social exchanges. As a result of making an AHP analysis for general park users, vegetable garden users there were clear differences in the targets which each subject put emphasis on in relation to the construction and operation of vegetable gardens. General park users recognized a vegetable garden as a park where park functions and the functions of the vegetable garden coexisted. On the other hand, vegetable garden users viewed it as a space where they attached importance to the functions of the vegetable garden like an allotment. Last, this study contemplated subjects related to the construction and operation of vegetable gardens which had to be considered in the future. Vegetable gardens tended to be biased as personal hobby places. It was viewed that the main reason was insufficient support activities for vegetable garden education and exchange programs originally planned when vegetable gardens had been constructed. Vegetable garden users recognized vegetable gardens as places for individuals' farming activities like allotments. For the desirable operation of vegetable gardens, it would be necessary to give priority to the park management before the production activities in individuals' vegetable gardens. The important role of the government would be to build the base through the provision of education and opportunities so that a local resident organization could actively participate in the management of a vegetable garden after a vegetable garden was constructed. It would be necessary to make a use survey and an awareness survey for users conducted in this study on a regular basis because the surveys could be important basic data in the decision-making process for the sustainable operations of the vegetable garden.

무, 적양배추, 청경채, 메밀 및 브로콜리 씨앗을 이용하여 새싹채소 및 성장이 완료된 일반채소를 재배하였다. 이들에 대한 비타민 함량을 측정한 결과 각 시료에 따라 큰 편차를 나타내었으며, 비타민 $B_1$은 싹이 트면서 그 함량이 감소하거나 검출되지 않았다. 이는 비타민 $B_1$이 성장에 사용되는 영양소이기 때문인 것으로 판단된다. 새싹채소의 무기물 함량은 일반채소 보다 2~10배 높게 나타났다. 새싹의 성장에 다량 이용되는 무기물은 칼륨이었고, 나트륨은 가장 적게 소비되었다. 일반채소에 비하여 새싹채소가 그 $\alpha$-amylase 활성 및 종합당화력이 높은 것으로 나타났으며, 이러한 경향은 이들을 이용하여 가공한 동결건조분말에서도 동일한 경향을 나타내어 전체적으로 싹 틔움에 따라 효소활성도가 비례적으로 증가함을 확인할 수 있었다. 새싹채소의 장점은 각종 영양소가 풍부하고, 가정에서 직접 재배가 가능하여 농약이나 화학처리를 하지 않기 때문에 안심하고 먹을 수 있다는 점인 것으로 판단된다.

Purpose: Considering the various health benefits of vegetables, it is necessary to identify maternal correlates of vegetable preference and consumption in children for shaping desirable vegetable-related eating habits. This study aimed to investigate the maternal factors related to vegetable preferences and consumption in preschool-aged children. Methods: This is a cross-sectional study that surveyed 303 mother-child pairs (146 boys, 157 girls) to explore general characteristics, vegetable preferences, and cooked vegetable consumption in mothers and children using a questionnaire method. Maternal correlates of the child's vegetable preference and consumption were tested using a generalized linear model using SAS program. Results: Mothers' vegetable preferences and consumption were significantly higher than those in their children (p < 0.001). Mothers' vegetable preferences showed a significant positive correlation with the vegetable preferences of their children (mother-son, p < 0.001; mother-daughter, p < 0.001). Additionally, mothers' cooked vegetable consumption showed a significant positive correlation with the cooked vegetable consumption of children (mother-son, p < 0.001; mother-daughter, p < 0.001). Mothers' vegetable preferences and consumption respectively increased those of their children, in both boys and girls. Conclusion: Findings that mothers' vegetable preference and consumption correlates of children's vegetable preferences and consumption, indicate the importance of the mothers' role in increasing vegetable consumption in children. Mothers should be aware of the effects of their vegetable eating habits on their children's vegetable consumption and try to develop healthy eating habits. We suggest that the government or local communities provide nutrition education for mothers to adopt healthy eating habits and present information to educate their children on food and healthy dietary habits.

This paper reports the basic performance of a naturally aspirated DI diesel engine which is used widely in industry and agriculture when vegetable oils are used as fuel substitutes. In this paper, the properties of vegetable oils as diesel fuel were investigated and the load-performance of diesel engine when vegetable oils were used, as tested compared against diesel fuel. The general objective of this investigation is to realize an efficient, clean, and low carbon deposit combustion of the vegetable oils in diesel engines, showing their feasibility as diesel fuel substitutes. The results of this experiment were as follows; (1) Compared with diesel fuel, the droplet size of vegetable oil is very large. (2) Compared with diesel fuel, rapeseed oil, palm oil, and their blend fuels offered lower smoke, lower NOx, ower engine noise, and high thermal efficiency in a D.I. diesel engine However, there were carbon deposit and piston ring sticking problems with long-term operation. (3) For ethanol-rapeseed oil blends, a 10-20% of ethanol content is recommended to enable lower BSHC and less smoke without a remarkable increase in engine noise compared with pure rapeseed oil. (4) A 10% oxygen content in the vegetable oils is contributed to reduced smoke emission.

Straight vegetable oil (SVO) is widely recommended as fuel for diesel engines in general and especially for marine diesel engines. However, SVOs used directly as fuel for diesel engines may cause problems for the engines; SVOs blended with diesel oil are a better choice. To widen understanding of the possibility of using blended SVOs as fuel alternatives, this paper presents results of experimental research on the combustion of blended straight vegetable oil in a marine diesel engine's cylinders. Results show that the fuel combustion process have the same curves as in simulations and, in the case of using blended fuels with up to 20% palm oil, the test diesel engine technical parameters such as engine output, exhaust gas temperatures, and specific fuel consumption are very similar to those of diesel oil (DO). Based on these results, marine diesel engines are strong potential applications and particularly recommended for the use of SVO blends.

This paper is aims at identifying the minimum farm size of the greenhouse vegetable cooperatives. Farm cooperative is one of the institutional measurments for the seeking of economy of scale which could not be found in family farm. In this paper 5 cooperatives and 5 farmhouseholds which have been managed vegetable greenhouse were surveyed. The results are as follows; First, cooperatives had 29.3% less on the fixed costs, and received 43% more on prices than general vegetable farmhouseholds. This means that the cooperatives have economy of scale. Second, to establish full organized coopratives, cooperative sizes must be more than 4,582 pyung, considering the government target which will be loaned 80% goverment loan of total facility costs with no subsidy.
