The purpose of the research is to identify the optimal seeding quantity of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria as leguminous woody plants for the cut-slope revegetation. To investigate the coverage ratio and appearance frequency, we divided Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria into five treatment groups with various quantities of 0.0g/m2, 1.0g/m2, 2.4g/m2, 3.8g/m2, and 5.2g/m2. For each treatment group, we mixed the identical quantities of herbaceous flowers (Lotus corniculatus var. japonicus, Dianthus sinensis, Aster yomena and Pennisetum alopecuroides) seeds and cool-season turfgrasses (Festuca arundinacea and Poa pratensis) seeds. In this result, as the seeding quantity of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria increased in the spray, the coverage ratio for leguminous woody plants appeared to increase whereas the coverage ratio decreased in herbaceous flowers and cool-season turfgrasses. However, when the seeding quantity of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria exceeded 3.8g/m2 in the spray, the coverage ratio of leguminous woody plants rather decreased compared to four treatment groups less than 3.8g/m2 seeding ratio. Based on the longitudinal data of coverage ratio in five treatment groups, we observed the gradual process of a short-term succession in which the dominant species shifted in the following order: First, cool-season turfgrasses; Second, herbaceous flowers; Third, leguminous woody plants. Comparing the appearance frequency of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria, Lespedeza cyrtobotrya appeared more frequent in 2014 whereas Indigofera pseudo-tinctoria appeared to be relatively more frequent in 2015. As a result, Indigofera pseudo-tinctoria was discovered to be a dominant species among woody plants. In this study, we observed that the optimal seeding quantity of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria was 2.4g/m2∼3.8g/m2. Moreover, the coverage ratio of 29.1%∼35.4% and appearance frequency of 4.6plants∼5.8plants were found in the condition of optimal seeding quantity.

'코펜하게나이즈 지표'를 활용한 청주시 생활권 자전거환경 평가
문석기,유병득 청주대학교 산업과학연구소 2016 産業科學硏究 Vol.33 No.2
To evaluate the bike-environment of neighboring community in Cheongju, 'Copenhagenize Index' - which was developed for the purpose of evaluating bike-environment of world cities. For the study, 13 Index system was revised to 10 Index system appropriate for Chongju. Several Indexes judged be difficult or impossible to apply were changed or discarded considering the regional environments. Questionnaire items to each Indexes were developed and surveyed as a next step. Evaluated bike-environment of Cheongju was scored point 50 - which is very low score comparing to Amsterdam(83) or Copenhagen(81). Among 10 indexes, 'Bicycle Culture' and 'Social Acceptance' highly scored at 8.82 and 7.08 each. But "Perception of Safety' and 'Urban Planning' were low scored at 2.92 and 3.19. Therefore, Cheongju City government should consider bicycle safety education, bicycle plan to lower the risk of bicycle accidents, and a balance road system. This results indicate the future orientation of Cheongju's bicycle policy precisely.

Local Agenda 21 organizations have been founded at the most divisions of local government in Chungcheongbuk-Do, but there has been no methods to monitor the total Sustainable Development trends. For the alternative solution of that problem in the Province, this study purposed (1) to develop Indicators fit to this Province (2) to examine the availability of the developed indicators adopting to each division section. Indicators were developed and examined by fields and Quantity / Quality considerations. As a 1st step, committee -composed with field professionals each- selected and developed Quantitative Sustainable Development Indicators(SDIs) optimized to Chungbuk-Province through critical discussions proposing Qualitative Indicators as a suggestion. In 2nd step, developed Indicators were applied and tested upon each divisions. Statistic data were used to calculate indices. 3rd step is adoption stage of Qualitative Indicators which were tested with questionnaire survey analysis. As a results, SDIs for Chungcheongbuk-Do -38 Quantitative SDIs within 4 provisions of 11 items with 8 Qualitative indicators categorization be put off- is developed. With the application test, 5 Quantitative Indicators- were found to be not adaptable because of lack or none of statistic data. Among the 8 Qualitative Indicators, 3 pairs found to be similar results in each pair which needed to be integrated into one. With them, bio-species related and health related Indicators were proposed to be newly added. Nation wide Sustainability comparison between divisions and Ecological Indicator selection are another themes to be considered.
