This study was conducted to identify the regional specialization that occurred during industrialization of agriculture. It examined patterns in oriental melons as one of the produce leading the development of the domestic protected horticulture sector. Oriental melons have been cultivated indoors for a long time. Seongju-gun, Gyeongsangbuk-do is specializing in oriental melon cultivation through increasingly intensive production and spatial concentration and is now the largest oriental melon production area in South Korea. This paper first discusses the production intensification and spatial concentration of oriental melon cultivation at the national level and then examines the specialization of oriental melon cultivation in Seongju-gun in terms of land use, cultivation facilities and related technologies, and the division of labor. This examination was based on relevant statistics and in-depth interviews with main actors from the area.

This study has been carried out to design the standards of rock bolts which are recommended to be used for supporting material in Seong Ju tunnel, Under recently planned to construct. Due to the weak bedding rocks along the Tunnel, NATM supporting method is assumed to be applied and the design and calculation for rock bolts which are important material for this supporting method. Though the study, the results obtained are as follows. 1) The rocks defined s coarse sandstone, fine sandstone, medium sandstone, sandy shale and silty shale are normal rocks in strength, and black shale, greywacke and conglomerate are weak rocks in strength. 2) When the length of 3∼4meters of rock bolts are used, the distances of bolts are supposed to be 1.3∼1.8m in sandstone and 1.3∼2.0m in shale and for greywacke the distance should be 1.5m.
