This study identifies the spectrum of different forms of sharing labor in farm houses following the increase in the production of organic produce and deals with the gender division of labor and every day life of the farm households. The increased labor burdens of organic farming give more work opportunities to wives, weakening the gender barriers. However, some of the farm households seeking for economic feasibility are strengthening the gender barriers by specialized work divisions, leading to outside order labor of harvest, sorting, and packaging in order to increase efficiency in agricultural management in extreme cases. Even in the alternative distribution system, farm households has become subject to the distribution system as it is shown that coop claimed the segmentation of sorting work. This is because the convenience of the customers goes before the advantages of producers. Jinju, seeking for economic feasibility, has established the springboard for growth by greenhouse through monoculture and specialization and are operating economic growth stably. Farm couples with this condition, where their incomes are relatively high, are attempting to recharge their energy during low seasons. It is expected that this will be a model case of conventionalization of organic farming. Significance of organic farming in this matter is discussed.

This study was designed to analyze the possibility to enter the Chinese market aggressively by giving light on the factors which have effects on the continuous intention of Shanghai consumers to purchase environment-friendly foods, and the purchase of Korean environment-friendly foods. The objects of analysis were the 209 consumers living in Shanghai, China. As for the analysis method, the frequency, percentage, crossing analysis, χ²-test and logistic regression analysis were carried out, making use of SPSS PC+ 13.0. The study results are as follows. Firstly, it was identified that the decisive factors, such as good taste, health of family, freshness, food shop in a department store, international quality authentication, diversity of items and number of family members, had effects on the possibility that the consumers in Shanghai, China would purchase environmentfriendly foods continuously, showing the meaningful variables. Secondly, as for the decisive factors having effects on the possibility to buy Korean environmentfriendly foods continuously, it was identified that good taste, health of family, freshness and price cutting were the meaningful variables. Therefore, it is necessary that to set up a export promotion strategy to make the Shanghai consumers get interested in Korean environment-friendly foods and choose to buy the foods.

This paper examines the impact of reliability on consumers’ demand for environmentally friendly agricultural products using ordered logit model. We survey 100 housewives living in the capital region and five metropolitian cities cross sectional data in 2007. This paper especially estimates the impact of instrumental factor, such as history tracking system, provision of information, safety assurance and labelling of brands on the consumers’ demand. The main results show that provision of information and safety assurance affect consumers" demand more confident than others. In order to motivate consumers to buy more environmentally friendly agricultural products, the safety should be assured and more information on production and marketing channel should be labelled.

This experiment was carried out to investigate the effect of different feed conditions on growth, cast production and conversion efficiency of organic matter to the earthworm. The experiment was tested on cow manure(CM) mixed with rice hulls (RH) or rice straw(RS). The mixture ratios were designed as one time, two times and three times of cow manure volume, respectively. The CM and RH mixtures resulted better on growth rate, reproductive efficiency and wormcast production than those for CM and RS mixtures. Especially on three times of RH mixture showed the highest growth characteristics compared to the other mixtures. Although both were between 20 and 34 on carbon and nitrogen ratio, the result inferred that the difference on the growth might have been caused by feeding conditions. On the mixtures of cow manure with rice hulls(CM+RH) was significantly higher on values on the conversion rate and conversion efficiency of organic matter to earthworm tissues than the mixtures of cow manure with rice straw(CM+RS). The most concerned point of the mixture of earthworm feed is that high contents of volatile solid and total carbon that increases in conversion efficiency of organic matter to earthworm tissues, and also causes the increase in growth rate and reproductive efficiency. The wormcast could be used as a valuable plant growth medium or soil conditioner for sustainable agriculture and it may be due to their high qualities of physico-chemical properties.

In this study, the effect of commercial organic growth medium amended with different ratios of vermicast on the growth of rice seedlings. The amended ratios of vermicast were 0% (control), 5%, 10%, 20% and 40%, respectively. A bioassay with two rice varieties (Chucheng and Black) was conducted to assesses the amendment effect of vermicast on the seedling growth in two potting methods. In potting treatment, the Chucheng variety with late maturity showed significantly higher values on growth parameters excepted root weight (RW) up to 20% and Black variety with early maturity up to 10% amended with vermicast, respectively. In floor layering treatment, all of the growth parameters significantly increased up to 5% amended with vermicast in both rice variety. The seedling growth of rice in floor layering treatment attained the highest values at lower amended ratios of vermicast than those of potting treated only, it may correspond with increased uptake of nutrient by elongated root grown under the layering amendment of vermicast. Vermicasts can be used as soil amendments or components of plant growth medium for seeding organic agriculture.

This study was conducted to determine the effects of different types of hilly pasture grazing on growth and meat quality in organic Korean black goats, and to obtain basic data for the production of organic goats. A total of 40 goats with similar age and BW were equally allocated to four dietary treatments in a randomized complete block design. Dietary treatments included grazing types of four different hilly pastures; T1: forages types, T2: organic forages types, T3: native plants types, and T4: browse types, respectively. The trial lasted for 174 days from 15th of May to 5th of November, 2007 in Livestock Genetic Resources Experiment Station, National Institute of Animal Sciences. At the end of trial, all animals were slaughtered to analyze carcass characteristics and meat quality. Average daily gain was significantly (p＜0.05) higher for T1 treatments than for others. Dressing percentage was significantly (p＜0.05) higher for T1 and T2 than for T3 and T4 treatments. Meat percentage of T1 treatments was significantly (p＜0.05) higher than those of other treatments. For meat properties, crude fat content was highest in T3 treatments. Linoleate (18:2n6) and linolenate (18:3n3) contents tended to be higher in T1 than those of other treatments, while arachidonate (20:4n6) content tended to be higher in T3 and T4 than that of other treatments. Shear force was lower (p＜0.05) for T3 than other treatments. For sensory results, juiciness and tenderness tended to be greater (p＜0.05) in T2 and T3, and flavour tended to be greater (p＜0.05) in T3 and T4. The results indicated that grazing in hilly pastures for organic Korean black goats was somewhat less in their performances and carcass characteristics, but not behind in the meat quality and physical characteristics as compared with the conventional regimen. Therefore, it would be expected that goats grazing in hilly pastures made it possible to produce organic animal products with a high safety and also might lead to increase of breeders income and consumers satisfaction.

In order to investigate any differences of the characteristics of goat milk according to seasons and individual farms, we analysed and compared the components of fat, protein lactose, total solid, solid-not fat (SNF) and cells of goat milk collected from 8 individual farms between December 2006 and June 2007. Milk fat content has shown higher values in December to March than in other seasons, and SNF appeared especially higher in February. However, lactose content was not different according to seasons. Regional differences of milk components were not big at all either. Milk components from goats were in general similar to cow milk except a little lower fat content, but appeared higher than mare milk. Production of goat milk is in difficulty in aspects of balancing demand and supply due to its seasonal reproductive system. For the future of goat milk industry, it is necessary to develop various products of longer storage life.

The effects of heat and formaldehyde treatments of soybean meal and rapeseed meal on ruminal release of minerals from the meals were studied on three sheep fitted with rumen cannula. Oilseed meals were treated at 133, 143℃ for 3h or added with formaldehyde at a level of 3, 5g/㎏. The ruminal release of P, Ca, Mg, Cu, Fe and Zn from the oilseed meals was examined using the nylon bag technique. Effective degradabilities of minerals in the oilseed meals were reduced by both treatments. The results suggest that rumen bypass treatments of oilseed meals prevent the release of minerals from the meals during rumen digestion and suppress the availability of mineals for ruminants. Eventually, the increase of heavy metal pollution in soil is anticipated due to the increase of mineral content in the feces of ruminants by ruminal protein bypass treatments.
