In this paper, we estimated the economic impacts of Korea-EU FTA on the agricultural sector in GyeongGi-Do. In particular, we estimated the economic impacts of agricultural production decrease resulting from Korea-EU FTA for 31 sub-regions in GyeongGi-Do by 15 industrial sectors. We employ a regional economic impact model combining a regional input-output model with a spatial allocation model. We found that the size of inter-industrial impacts are quite different across regions. Our results suggest the importance of agricultural and industrial policy considering the impacts of industrial sectors at the regional level.

The New bicolor spray rose (Rose hybrida Hort.) cultivar was developed by line selection in 2000 at the Flower Breeding Research Institute, Gyeongnam ARES. Characteristics were investigated three times from 2003 to 2006. ‘Yellow King’ was crossed between ‘Spring Time’ and ‘Flair’ and it has a Yellow Orange-group color (RHS No. 16A), few thorns and spray flower with a good harmony between ray floret and flower center. The vase life of cut flower was 9.1 days. It was registered as commercial cultivar in 2006. This new cultivar could be planted in most of greenhouse production region of Korea and will be released to general rose growers in 2007.

홍삼의 물추출물을 장기간 흰쥐에 급여했을 때 흰쥐 간의 이물질대사효소 활성도 유도에 미치는 영향을 조사하였다. 홍삼 물추출물의 급여농도는 25 mg/kg body weight이었으며, 간의 이물질대사효소 유도제는 항경련제 PB (80 mg/kg)와 발암제 3-MC (20 mg/kg)을 사용하였다. 간에서 이물질대사에 관여하는 cytochrome P-450의 함량, cytochrome P-450 dependent monooxygenase인 ECOD와 BPDM, cytochrome P-450 reductase와 GST의 활성도는 PB와 3-MC 투여에 의해서 대조군과 홍삼투여군 모두 크게 증가되었다. 흰쥐의 나이가 3개월에서는 두 유도제를 투여했을 때 이물질대사효소의 활성은 대조군이 인삼투여군에 비해 상대적으로 더 많이 유도되었다. 그러나 12개월에서는 두 시험군 모두 유도정도가 감소하였으나 홍삼투여군은 그 활성도 감소정도가 대조군에 비해 상대적으로 크지 않았다. 한편 두 그룹 모두 이물질대사 효소 중 cytochrome B5 함량과 cytochrome b5 reductase의 활성도는 PB와 3-MC 투여에 의해서 뚜렷한 차이를 보이지 않았다. 따라서 이러한 결과는 흰쥐에 홍삼의 장기간 급여는 간에서 효소유도제의 이물질대사효소유도 정도를 조절하여 무독화에 기여할 수 있다는 것을 의미한다.

Hierarchical Planning based on Abstraction of World Elements and Operators(HiPAWO) is proposed for mobile robots task planning, where abstraction of world elements is used for hierarchical planning and abstraction of operators is used for hierarchical decomposition of abstracted actions. Especially, a hierarchical domain theory based on JAH(Joint of Action Hierarchy)-graph is proposed to improve efficiency of planning, where a number of same actions are included in both adjacent hierarchical levels of domain theories to provide relationships between adjacent hierarchical levels. To show the validities of our proposed HiPAWO, experimental results are illustrated and will be compared with two other classical planning methods.

In order to improve the water environment at urban streams in Korea, several river restoration projects have been initiated for past few years. This study evaluates the impact of diverting water application at the riverhead of Onchun stream through the monitoring program for several water quality and ecological parameters. Various water quality parameters and ecological item such as benthic macroinverterates has been investigated between 09/05 and 12/06. Analysis indicates that the application of diverting water from Nakdong river to Onchun stream distinctly improved several water quality parameters such as, PH, BOD, TN, TP and concentrations of heavy metals. Low flow augmentation also improve ecological indicies such as the diversity index of benthic macroinvertebrates. Generally speaking, releasing addition water from head water of Onchun stream improves various water environmental characteristics.

This study compared the performance of a bioscrubber, a biofilter, and a combined system of bioscrubber and biofilter employed being operated at the laboratory-scale. for the removal of hydrogen sulfide. The bioscrubber maintained 100% removal of hydrogen sulfide up to inlet load of 56 g-S/m3․hr, while the removal efficiency was decreased with the increase of inlet load. The biofilter showed 100% removal efficiency up to inlet load of 126 g-S/m3․h and the maximum elimination capacity of 126 g S/m3․h for the inlet load of 224 g-S/m3․h. On the other hand, the combined system of bioscrubber and biofilter showed 100% removal for an inlet hydrogen sulfide load of up to 85 g-S/m3․h and the maximum elimination capacity of 153 g-S/m3․h for inlet loads of 224 g-S/m3․h.

Recently, it is demanded to study about landscape. Landscape is an environment factor for improving life, a social resource for establishing image and identity of the area and also a tourist resource for earning profit. With this importance, landscape planning is being performed by local governments. However, classification for a rule about landscape planning is not prepared yet. For this purpose, classification of landscape is definitely required. Therefore, this article focuses on presenting method of classification Natural and Rural Landscape. We used Arcview 3.2 to draw watershed of the site, and calculated the percent of landform. We also took a picture which explain the landscape and made a survey of classifying the landscape. Due to this study, we were able to frame an algorithm of the landscape classification. This will contribute to classify the landscape type. This study needs more specific researches because it was supposed to target the entire Gyeonggi-Do however it only covered several regions. Through this results, it would be expected to develop the map of landscape character.

Due to the dramatic industrialization in Korea, rural area has been degraded with incurable problems including community aging, emptying and liabilities overburdens. Rural amenity, the intangible resources that the rural area itself has, is regarded as a breakthrough that can revitalize the rural communities. In fact, the rural area and communities have lots of amenity resources that have been overlooked. Rural area has kept traditions and open green spaces which are highlighted in these days since the life quality has been upgraded and working days in a week was cut off to 5 days. Institute of Rural Resources Development realized the importance of rural amenities and offered the nation wide survey project for rural amenity resources. In this article, the survey project that was implemented by the Korean Society of Rural Planning was narrated in terms of methodologies and procedures. Also the results and the problems were addressed.

Long-term passive diffusive samplers(PDS) have been used to measure NO2 and SO2 concentrations at 21 sampling sites in Daejeon, Korea during the period of January 2000 - December 2002. The spatial distributions of annual NO2 and SO2 concentrations were mapped. Average annual NO2 concentration over the sampling period was 28.5±12.5 ppb, ranging from 1.2 to 81.7 ppb. Average annual SO2 concentration over the sampling period was 7.7±4.8 ppb, ranging from 0.6 to 26.8 ppb. On average, NO2 concentration was approximately 5.8%(1.6 ppb) larger in 2002. SO2 concentration was decreased by 13%(1.1 ppb) during the sampling period. The seasonal variation of NO2 and SO2 concentration was observed with a tendency to be higher in fall and winter. NO2 and SO2 concentrations measured at different site types(patterns of land use) show significant difference. The observed difference in concentration was associated with difference in emissions of NO2 from motor vehicles and SO2 by non-traffic fuel consumption for heating.
