Kyoudou seikatsu to roushi mondai
Nouka no keiei to menyou shiiku
Saikin no denmāku to nougyou no gouriteki kyoudou keiei

Nouhanki ni okeru kyoudou sagyou to kyoudou suiji oyobi kyoudou hoiku
Seikatsu mondai to nouson mondai
Nouhanki no kyoudou sagyou to kyoudou suiji oyobi hoikujo
Wagakuni genji no shakai mondai to shiteno jinkou mondai
Nougyou kyoudou kumiai no gappei mondai to kumiaiin soshiki mondai ni kansuru sougouteki kenkyuu
Oubei no roudou mondai to wagakuni roudou mondai no genjou
