This study aimed to analyze socioeconomic effect of eco-friendly free school food supply system by Seoul, which has been consistently extended since 2011. To do so, effect of eco-friendly free school food supply system on the beneficiaries, Seoul citizens, was analyzed by using 'labor & income panel', while that on rural society was analyzed by using the surveys on the eco-friendly agricultural product supply performance by the 'Eco-friendly Agricultural Products Retail Center' as well as for students, school parents, nutrition teachers and nutritionists. The results of analysis showed that eco-friendly school food supply system contributes to income redistribution among the Seoul citizens to a certain extent, provides the eco-friendly agricultural product producers in the rural society with the stable market, and positively influences them to secure stable incomes. In addition, eco-friendly free school food reduced the amount of carbon emissions through the use of environmentally friendly agricultural products resulting in environmental improvements and economic benefits. Considering such effects, free school food supply using the eco-friendly agricultural products needs to be consistently maintained in the future without politic change by political ideology and to be extended to middle school level in medium and short-term.

The purpose of this study is to analyze the effects of abolishing the low-pesticide agricultural product certification on environmentally friendly farming. A survey was conducted to quantitatively analyze farming practices and factors that change farming practice. It was found that only 17.0% of low-pesticide fruit farmers said that they will change their farming practice into organic or pesticide-free farming. With regard to the factors of farming practice change, binomial logistic regression model was applied for the analysis. In the analysis, it was found that farmers who grow the low-pesticide agricultural product are more likely to change their farming practice into organic or pesticide-free farming, as their expected price of organic or pesticide-free products is high, their area size is small, price premium of low-pesticide agricultural product is low, the frequency of their training is high. It is necessary to enhance the direct payment system to enlarge organic and nonpesticide acreage, and pest management techniques for fruits should be developed for low-pesticide fruit farmers to change their practice into organic and nonpesticide practice. Dissemination of cultivation manual, introduction of insurance to farmers, improvement of certificate system, and advertising and marketing of environment-friendly agricultural products are useful to develop environment-friendly agriculture.

The goal of this study is to promote the spread of environmentally friendly agricultural products, which have been receiving a lot of attention lately, as a way to improve food safety and quality. As a result of the increased labor input, increased production costs, and an aging population, environmentally friendly agriculture is making it more difficult for farmers to expand their enterprises. In the meantime, consumers find it difficult to spread eco-friendly agricultural products due to their high expectations for safety and quality, as well as the desire to purchase products at a reasonable price. Previous studies have revealed differences in perceptions between eco-friendly agricultural producers and consumers. In light of this, this study divided consumers based on their characteristics (such as age, purchase history, health concerns, etc.), and different policies were proposed in order to increase purchasing factors for each group based on their characteristics. In order to gather information for this study, general citizens were asked about their perceptions of eco-friendly agricultural products, future purchase intentions and awareness, reliability, necessity, purpose, and information sources. A two-step clustering analysis was conducted using nominal and continuous variables simultaneously. The paper presents the three derived group differences (senior organic interest group, middle-aged organic interest group, and indifferent young organics) as well as group differences for the purchasing/non-purchasing factor analysis and policy improvement for each group. An eco-friendly agricultural product distribution proposal was made at the end of this article.

This study was designed to assess the perception and use of weaning diets and to serve as a guideline of processed weaning diets through a survey focused on the Gwangju-Jeonnam regions. The following results were obtained. Most subjects mixed 'home-made' and 'commercial' weaning diets and considered weaning diets as 'a diet for supplementing insufficient nutrition'. The most frequently used type of weaning diet was 'a kind of gruel with vegetables or meat', followed by 'boiling powder with water' and 'grinding or crushing fruits'. Two thirds (68%) of subjects had experienced buying weaning diets, mainly a powder type. The most common reason to buy weaning diets was 'troublesome', followed by 'excellent nutrition', 'convenient to go out', and 'don't know how to make'. The following results according to factors were found. The types of provided and of weaning diets were significantly different by age; the understanding of weaning diets, by education and mothers' employment; and where to get information about weaning diets, by economic status. The highest request for developing weaning diets was a type of 'powder' and 'gruel', and the highest cooking type was 'adding boiling water', followed by 'a semi-cooking product' and 'a finished product'. 'Retort pouch' package, a 'single' package unit, and 'keeping cold' were also requested by the participants. A desirable package unit in developing weaning diets was significantly different by mother's employment; the cooking type of product, by economic status; a way to keep product, by mother's employment; and package types, by education and economic status. When weaning diets were made by environmentally friendly agriculture, 69.5% of subjects were willing to purchase them. With the increase in economic status, education, and employment rate, the use of weaning diets on the market will increase. For this reason, correct nutrition education is needed. With the increasing demand for environmentally friendly agriculture, a variety of weaning diets should be developed to meet this demand.

Eco T-shirts have become a part of environmental campaigns following social trends toward eco-friendly designs. With the demand for such designs expected to grow, there has arisen a need for higher product variety. In the past, eco T-shirts were designed to convey messages about the protection of nature through the use of environmentally friendly text or images. However, in order to respond to the preferences and emotional needs of Koreans, designs should cater to their characteristics and tastes. To this end, this study used a Whan-ki Kim-inspired motif to develop an eco-friendly design tailored to Korean perspectives. It is believed that this process can not only result in a distinctive eco T-shirt design, but also make it globally competitive. With regard to research methodology, a total of 41 paintings of Whan-ki Kim were analyzed and classified into four major themes or key values expressed in modern eco-friendly fashion designs: naturalness, indigenousness, harmony between nature and man, and harmony between natural and artificial beauty. Employing a wide range of CAD techniques and varying forms, the themes were developed into 28 T-shirt designs after their forms, tones, and textures were fully explored. This study demonstrates the possibility of designing creative, aesthetic, and high value-added eco T-shirts through motif development. In addition, it successfully integrates Korean paintings in the development of T-shirt designs aimed at communicating environmentally friendly messages.

Metabolomics is the study of global metabolite profiles in a system (cell, tissue, or organism) under a given set of conditions. Metabolomics has its roots in early metabolite profiling studies but is now a rapidly expanding area of scientific research in its own right. In this study, the applications of metabolomics in natural product studies are explored. Ginseng is a well-known herbal medicine and has various pharmacological effects, which include antiaging, anticancer, antifatigue, memory enhancing, immunomodulatory, and stress reducing effects. Metabolomic analysis of organic acids has not been performed for evaluation whether ginseng has been cultivated using conventional or environmental-friendly farming methods. In this study, profiling analysis was conducted for organic acids (OAs) in ginseng roots produced using conventional or environmentfriendly farming methods at five locations in each of five regions. In OA profiles, lactic acid was the most abundant OA in all regions, with the exception for environmentally friendly farmed ginseng in two of the five regions, in which glycolic acid was most abundant OA. OA profiles in all regions showed isocitric acid levels were increased by environment-friendly cultivation, which suggests metabolic differences associated from farming method, and that isocitric acid might be a useful discriminatory biomarker of environmental-friendly and conventional cultivation. The results of the present study suggest metabolomic studies of OAs in ginseng roots might be useful for monitoring whether ginseng has been cultivated using conventional or environmentally friendly farming methods.
