The purpose of this research is to clarify the valuable industrial heritages of rice mill industry complex remained in Incheon. In order to clarify the formation of integrated historical setting of rice mill industry of Incheon, we analyzed the old map of Incheon’s old Jemulpo area and data on address, locations and happenings surrounding rice mill factories and relevant facilities. From here, we could find out the 4 representative rice mill industry area of integrated historical setting and 2 other supporting service area for rice mill industry in old city center of Incheon. Specifically, we could figure out the incremental stages to establish the rice mill industry in Incheon. In the first stage, the rice mill factories were established near foreign settlement area where trading offices and warehouses were equipped. And the second stage reflect the needs of expanding area for Japanese capitalism with the new landfill area. In the final stage, Korean rice mill owners established the korean laborers community near Korean residential area. This formation of integrated historical setting reflecting Incheon’s rice mill industry is the identical industrial heritages and urban structures to show the tension and conflict between Japanese and Korean laborers’ life in the Japanese Colonial Period.

In order to calculate the energy basic unit for industry complex, Statistic Analysis were carried out. As a result of analysis, this paper propose new calculated fuel basic unit, electric power basic unit and energy basic unit. Also shows that overall mean fuel basic unit decrease, electric power basic unit increase and energy basic unit decrease as compared with the Notification No. 2009-29 of the Ministry of Knowledge Economy, that the rates of basic unit change of facility investment business type are all increase and the rates of basic unit change of energy intensive & labor-intensive business type are all decrease.

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were investigated in soil and pine needle samples taken from 16 sites of industrial and residential areas in Changwon, Korea to assess their distribution levels and to suggest the influence of industrial activities. PCDDs/DFs levels in the soil samples ranged from 0.57 to 20.79 pg I-TEQ/g dry weight with a mean value of 4.20 pg I-TEQ/g dry weight. PCDDs/DFs levels in the pine needle samples ranged from 0.39 to 8.75 pg I-TEQ/g dry weight with a mean value of 4.09 pg I-TEQ/g dry weight. In both soil and pine needle samples, the PCDDs/DFs concentrations in the industrial area sites were higher than those in the residential area sites. Homologue profiles in pine needle samples showed different patterns compared with soil samples. Based on the results of principal component analysis (PCA), it was confirmed that pine needles reflected a direct influence from local potential sources of PCDDs/DFs, showing a much higher degree of reflection than in soils. Pine needles are very useful as an indicator for monitoring or estimating the contamination of PCDDs/DFs in other areas which have been impacted by point pollution sources.
