Pulmoo School is a Christian-based school that follows the Danish folk high school model. It is located in Hong Dong-Myeon, Hong Sung-Gun, Chung Cheong Nam-Do, Korea and aims to educate rural children.Pulmoo School was established in 1958 and regarded the surrounding areas as one community. Ever since that time, the school has been making efforts to build a community-based society through cooperatives. During its early years, the school set up a purchasing cooperative and a credit cooperative in this community.The former became Pulmoo Consumer Cooperative in 1980 and the latter became Pulmoo Credit Cooperative in 1972, with both of them eventually becoming regional cooperatives. In the 1980s, agricultural products were directly sold to the capital area through Pulmoo Consumer Living Cooperative on the back of the Japanese organic agriculture movement. In addition, rice-duck farming was introduced to produce organic rice in 1994. In the following few years, amid policy developments concerning organic agriculture, the scope of organic agriculture branched into vegetables and animal products, and even into the processing industry.This was a result of great organizational changes that had been taking place in the community: Pulmoo Consumer Living Cooperative changed into Agricultural Cooperative, while the Hong Dong-Myeon Agricultural Cooperative developed into a union. Furthermore, the Pulmoo Credit Cooperative started selling production equipment to peasant households. In addition, a peasant association aimed at promoting the direct marketing of agricultural products was set up. As a result, Hong Sung-Gun including Hong Dong-Myeon has been regarded as the Mecca of organic agriculture in Korea.

日本最大の馬産地日高地域は、軽種馬生産を中心として各関連産業の集積産地として成立しているのである。さらに、日高地域は、その集積構造の中で大規模企業的経営層が多数の家族経営層を相手に多角的な事業(種牡馬事業、産地育成、繁殖牝馬の仔分・預託など)を展開することで成立している。この意味において、現在、産地に浸透している構造不況の影響は、小規模家族経営層だけではなく、大規模企業的経営層にまで波及していくものと考えられる。このことは、日本最大の馬産地日高地域全体に壊滅的な影響を与えることを意味する。そこで、本稿では、軽種馬産業集積地における大規模企業的経営と多数の中小規模家族経営と事業的な関連性を明らかにするために、日本最大の牧場Aグループと日高の生産者との関連構造を分析し、馬産不況がもたらす産地へ影響を明らかにしていく。この馬産不況の影響をみる分析視角として、現在深刻な経営危機にある産地競馬の廃止の影響を一つの指標として用いることで構造的な関連性を明確にしていくこととする。

The cooperative shipping system receives regulations from the historical development process. This becomes important for understanding the form and the function of the cooperative shipping system. In this study, the distinctiveness of the cooperative shipping system of Satsuma Mandarin in Ehime is analyzed by a comparison with Shizuoka. Characteristics of Cooperative shipping systems in both prefectures that succeeded prewar days are the following three points. The first point, whether it is a single-purpose cooperative or a multi-purpose cooperative depends on the development at prewar days. The second point, the base of shipping system is farmer's small-scale co-fruit sorting group. The third point, technical guidance to those farmers has been enhanced since prewar days.

As paddy fields were developed rapidly at the end of the Twentieth Century, Northeast China, especially Heilongjiang Province, became the main production area of japonica rice. The paddy fields, which were mainly developed by State Farms, have formed a productive base centering on the Sanjiang Plain. Beidahuang Group, which has become a huge group corporation now, provides a tremendous amount of japonica rice. It was set up on the basis of Heilongjiang Agriculture Company Limited (HACL), which is an aggregate of 16 excellent farms gathered by Heilongjiang Bureau of State Farms for japonica rice production, processing and marketing in 2002. Beidahuang Group has established a japonica rice production and processing system with the 16 farms as its foundation. Part of the rice produced by the company is sold to major cities in China by the Department of Domestic Trade, which has led to the formation of a large sales network. Another part is exported to foreign countries, including Japan, via China Oil and Foodstuffs Corporation (COFCO). Regarding the sale of paddies, it is conducted through the companyユs Department of Cereal Trade. A certain portion is purchased by the government for state reserves and the rest is sold to wholesalers as self-run provisions.Beidahuang Group possesses an enormous amount of cultivated land for japonica rice. Despite several difficulties in sales, it is undeniable that the company has already occupied an important place in the domestic market for japonica rice.
