This case study surveyed management situations of environmentally friendly farming(EFF) producers' organization and their main activities. Farmers are aging as an average age of 55-year old and producing fruit-bearing vegetables. The EFF did not increase farmer's income, however, price and income was stabilized more than that of conventional farming because of contract farming. Farm household liabilities are caused by purchasing agricultural machinery, materials and so on. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their EFF products. And they are guessing that EFF income will increase a little. For increasing of EFF income, they think that it is necessary to reduce production cost, produce high quality production, develop processing foods, enlarge contract farming and so on.

This study analyzed the management situation of two organizations that have produced environmentally friendly agricultural and livestock products. One organization sells and processes environmentally friendly agricultural products like as grains, vegetables, fruits and processing foods. Another organization processes and sells environmentally friendly livestock products, specially beef products. Indices of management analysis are stability ratio, activity ratio and profitability ratio. Stability ratio indices are debt ratio, net worth ratio, fixed ratio and current ratio. Activity ratio ones include fixed assets turnover and net worth turnover. And profitability ratio is showed through return on investment, net return on sales and return on equity.

One of the possible mechanisms of multi-drug resistance found in cancer cells is the over-expression of P-glycoprotein (P-gp). Studies have shown that compounds found in plants including vegetables and fruits not only have anticancer activities but may also modulate P-gp activity. The effect of flavonoids and organic isothiocyanates on P-gp activity was studied in human uterine sarcoma cell lines, MES-Sa (sensitive) and MES-SD/DX5 (resistant). The accumulation of daunomycin (DNM), a P-gp substrate, was approximately 10 times greater in the sensitive cell as compared to the resistant cells over the entire time course (up to 2 hrs).

The purpose of this study was to investigate basic data on the degree of parents' recognition and satisfaction with the use of environment-friendly agricultural products. The conclusions of this study are as follows. The survey on the use of environment-friendly products in households showed that 68.7% of the respondents used environment-friendly products at home. The frequency of purchasing organic products by household consumers showed that 25.1% of the respondents bought organic products one to two times per week. The most popular items of the environment-friendly agricultural products used were vegetables, comprising 63.9%. The households with more than 3,000,000 won of monthly income tended to consume more domestic livestock products (p < 0.05). In comparison to general agricultural products, environment-friendly agricultural products users showed higher satisfaction level with a better quality in term of safety, quality, nutrition, taste, appearance, diversity and price. The degree of satisfaction with safety was the highest ($3.8{\pm}0.68$), and price showed the lowest ($2.76{\pm}0.79$). The degree of parents' recognition of the governmental support for environment-friendly agricultural products showed that those who were aware of the supporting policy were 44.5%, but 55.5% of them didn't know about the fact that 46.6% of the respondents agreed that environment-friendly agricultural products should be used in more than 50% of the foods used for school food service. The respondents pointed out that vegetables (45%) sprayed with pesticide are the most urgent food item that need to be replaced by environment-friendly farm products.

서울시민을 대상으로 퇴비화 및 퇴비에 대한 일반시민의 의식조사를 실시하였다. 대부분의 시민들이 음식물쓰레기의 처리문제를 심각한것으로 인식하고 있었으며 응답자의 91.9%가 음식물쓰레기로 퇴비를 만들수 있다는 사실을 알고 있었다. 또한 화학비료보다 음식물쓰레기로 만든 퇴비를 선호하고 있었으며 가축분뇨로 만든 퇴비보다 음식물쓰레기로 만든 퇴비의 품질을 더 좋게 생각하고 있었다. 그리고 화학비료를 주고 재배한 채소보다 퇴비를 주고 재배한 채소를 좋게 생각하고 있었으며 10~20%정도의 비싼가격을 감수할 의사가 있었다. 또한 대다수의 사람들이 퇴비화를 위한 분리배출에 대해 협조할 의사를가지고 있었으며 음식물쓰레기는 소각이나 매립보다 퇴비화로 처리해야 한다고 생각하고 있었다.

To investigate the perception and consumption of imported and organic produce, a survey was conducted using a questionnaire in Seoul, Taejon and Cheongju from February to March in 1995. The responses of 350 housewives were analyzed. Most of the subjects (96.8%) know an increase of imported produce, and 86.3% thought that imported produce was not safe. Ninety-two percent of the subjects preferred domestic produce to imported produce. The reasons were for the support of domestic farming (36.7%), hazardous chemicals in imported produce (25.0%), good taste (24.1%) and high quality of domestic produce (13.1%). Seventy-eight percent of the subjects had purchased imported produce. The reasons for purchase were cheap price (67.7%), high quality (16.2%), and good taste (5.4%). Imported produce were purchased in the following order ; fruits such as banana, kiwi, orange and grapefruit, seasonings such as garlic and sesame, vegetables such as onion, braken and green onion, and beans and grains such as soybean, red bean, and barley. Most of the subjects (94.3%) had been informed on organic produce. Among these, 45.2% obtained the information by TV or radio. However, son for purchase was low residual chemicals (64.6%). The reasons against purchase were inconvenience of purchase (42.3%), high price (25.4%), and disbelief of low residual chemicals (19.7%). Therefore, domestic produce should be good in quality and taste, and be safe without residual chemicals in order to compete with imported produce with cheap price. Informations on organic and imported produce should be provided to consumers, and the distribution system of organic produce should be improved for consumers convenience.

어패류 섭취양상에 따른 총수은 및 유기수은의 체내 축적정도를 조사하기 위하여 1991년 6월부터 8월 사이에 경북지방의 해안지역, 도시지역 및 산간지역에서 남자국민학생 115명과 남자 성인 131명, 총 246명의 두발중 총수은 및 유기수은 함량을 수은분석장치 (Model IL 440)를 갖춘 원자흡광분광광도계 (Model IL 551)로 선택적 환원기화법에 의해 분석하였다. 학생군의 경우 생선 및 조개류와 생선통조림 및 어묵류를 선호하는 군의 두발중 총수은(각각 7.728ppm, 6.969ppm) 및 유기수은 함량(각각 6.610ppm, 5.885ppm)이 육류(총수은; 4.822ppm, 유기수은; 3.905ppm)나 야채류(총수은; 3.974ppm, 유기수은; 3.224 ppm)를 선호하는 집단보다 현저히 높았다(각각 p<0.01). 생선통조림을 먹는 방법에 따른 두발중 총수은 및 유기수은 함량은 그대로 먹는 경우가 야채사라다와 섞어서 또는 찌개로 먹는 경우보다 높게 나타났다(p<0.01). 생선통조림, 생선 조리반찬 및 생선회 섭취빈도가 많을 수록 두발중 총수은과 유기수은 함량이 많아 거의 매일 먹는 군이 거의 먹지 않는 군에 비해 2배 이상 높게 나타났으며(p<0.01), 생선을 주로 먹는 방법에 따라서는 회로 먹는 경우가 탕이나 구워서 먹는 경우 보다 현저히 높았다(p<0.01). 성인군의 경우 연령에 따른 두발중 수은 함량은 총수은과 유기수은 함량 모두 40대까지는 연령증가에 따라 증가했으나, 50대 이후는 약간 감소하였다. 직업별로는 어업 및 횟집 종사자가 농부에 비해 2배 이상 높았다. 또한 선호반찬 종류에 따라서는 생선 및 조개류를 선호하는 군이 가장 높았으며, 생선을 먹는 방법에 따른 두발중 수은 함량은 회로 먹는 군이 탕이나 구워서 먹는 군보다 2배 이상 높은 수준을 나타내었다. 생선회, 생선조리반찬 섭취빈도에 따른 두발중 총수은 및 유기수은 함량은 섭취빈도가 증가함에 따라 높아지는 경향을 보였다(각각 p<0.01). 이상의 결과로 보아 두발중 수은 함량은 어패류와 생선통조림의 섭취 빈도가 높을 수록 증가하였으나 중독증상을 나타낼 수 있는 농도에는 크게 못 미쳤다.

Soil trace elements and their bioaccumulation in agricultural products have attracted widespread concerns, yet the crop uptake characteristics of trace elements in different soil-plants systems have been rarely investigated. Experiments were carried out to investigate the effect of soil properties on trace element concentrations in cabbage and radish. Soil pH and total organic matter were major factors influencing trace elements transfer from soil to vegetables. Inclusion of other soil properties in the stepwise regression analysis improved the regression models for predicting trace element concentrations. Consideration of other soil properties should be taken into account for more precise prediction of trace element concentrations in the two vegetables, which could help quantitatively evaluate the ecologic risk of toxic trace elements accumulation in crops.
