  • IPCC(Intergovernmental Panel on Climate Change)는 향후 100년 동안 지구의 평균기온이 $1^{\circ}C$에서 $3.5^{\circ}C$ 상승할 경우, 각 기후대가 극방향으로 약 150~550km 이동할 것으로 예측하고 있으나, 과거 기후변동 연구결과들은 삼림의 이동속도를 100년간 4~200km로 추정하고 있어 식생이 기후대의 이동을 따라가지 못하여 사멸되는 지역이 발생할 것으로 예측되고 있다. 약 960km의 남북으로 긴 지형적 특성을 가진 한반도 역시 이러한 영향을 벗어나지 못할 것으로 예측되고 있어 기존의 기후변화 시나리오와 함께 삼림의 이동성을 고려한 영향연구가 요구된다. 본 연구는 IPCC의 새로운 기후변화 시나리오인 SRES 시나리오의 대기대순환모형(Global Climate Model, GCM) 결과와 AIM(Asia Integrated Model)/Impact[Korea] 모형을 이용하여 제작된 Holdridge 생물기후분류의 연구성과를 이용하여, CO2농도 배증시의 한반도지역의 자연식생 영향과 적응 가능성을 삼림의 이동성을 고려하여 평가하였다. 삼림의 이동속도를 0.25, 0.5, 1.0, 2.0(km/yr)로 변화시키며 2100년 한반도 자연식생의 기후 변화 영향을 평가한 결과, (1) 목본식물의 이동속도가 년간 1km 이상일 경우 삼림 피해가 미미하게 나타났으나 (2) 이동이 느린 0.25km/yr의 경우, 생육위험지역을 포함한 시나리오별 전체 피해규모는 A2(17.47%), A1(9.97%), B1(6.21%), B2(5.08%) 순으로 나타났으며, 삼림소멸의 경우는 A2, B2 시나리오에서 발생하며 A2 시나리오에서 한반도의 약 2.1%로 가장 크게 발생하였다. (3) 전반적인 생육위험 지역의 분포는 함흥만, 영흥만의 동해안지역에 집중되었으며, A2 시나리오의 극단적 소멸예상지역은 금오산, 가야산, 팔공산을 연결하는 지역에서 발생하는 것으로 나타났다.

  • 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.

  • Demands for housing has diversified recently due to low birth rate and the growth of aging population. Also, a share of idle houses and obsolete houses over 20 years old is gradually rising. Therefore, there is a need for a sustainable, environment-friendly improvement policy that is in line with a new housing paradigm and avoids full-scale new construction, such as a customized housing renovation plan considering local economic circumstances. Therefore, afforestation system applicable to buildings are assessed positively, but lack objective performance evaluation. Through one-year, long-term monitoring of replicated obsolete buildings that have poor insulation performance, this study calculated monthly average power consumption and analyzed power charges by applying pricing plans before and after the revision of progressive tax in order to examine economic effects expected by applying the afforestation system. In the obsolete buildings, the study showed that monthly average power consumption was reduced by 16.6kWh with 5.2% average reduction rate. Highest reduction was made in July at 11.3%. Aggregate monthly power consumption charges were relatively high in winter before and after the revision of progressive tax. Power charges reduction effect was highest in March when monthly power consumption was reduced to 300kWh level by applying the afforestation system.

  • In order to survive the competition, cities are trying to form an original city brand through attractive city contents. The purpose of this study is to investigate the factors of urban brand formation and to present the framework of the theoretical concept. The purpose of this study is to examine the main factors of city brand formation by examining the precedent studies of city brand, and to suggest new urban brand conceptualization based on this. In this study, we analyzed the factors of city brand which are mentioned in 20 major researches on the evaluation criteria or strategy among the previous studies on urban brands. As a result of the study, the main factors that form the city brand can be classified into 1) landscape factors, 2) administrative factors, 3) historical and cultural factors, 4) cognitive factors, and 5) empirical factors. Based on these factors, it is possible to form an original city brand, which is expected to enhance urban competitiveness in the future.

  • Outdoor lighting has become a necessary essential part of society for safety and comfortable space. However, inappropriate outdoor lighting leads to energy waste and poor landscape. Outdoor lighting is a very important social element, which enables us to conduct various activities at night in a safe, efficient and comfort way. River Thames in UK, Venice in Italy and Sydney in Australia is a good example of the coastal area. This paper aims to evaluate the light pollution of outdoor lighting in coastal area in Busan city. The Radiant Imaging ProMetric-1400 was used to measure the luminance of Gwangalli Beach, Marine City and Haeundae Beach. Compare to the CIE recommendation level the luminance of the all outdoor lighting were about 2~20 times higher. Outdoor lighting of the building facade luminance level and color should be particularly limited.

  • This study aims at analyzing of residents'attitudes and spatial structures in the rural villages reconstructed by the Rural Village Improvement Project(type A), and suggesting the guiding directions for planning rural villages. Six rural villages located in KyungGi province were selected for case study. The Major findings can be summarized as follows : 1) The ratio of type A project(newly planned village) in the total cases of the Rural Village Improvement Project has increased since 1990, In the majority(91.2%) of the type A project, the project area is below 2 ha and density of dwelling unit is below 40 households/ha. 2) The three spatial structures of newly planned rural village, i.e., Loop pattern, Cul-de-sac pattern, and Dendritic pattern, are identified. And the barns in the newly-build houses are categorized into the five types : the vertical addition type, the horizontal addition type, the vertical- horizontal addition type, the no- barn type, and the reused -barn type. 3) In the newly planned rural villages, the level of satisfactions for the quality of house and water & sewer system is remarkably higher than in the existing rural villages. These are the positive effects caused by the Rural Village Improvement Project. 4) The majority of the villagers think the improvement of the existing rural village, instead of redevelopment or newly planned village, is most desirable, which means the improvement of houses, roads, and sanitary facilities while preserving the spatial structures of the existing village.

  • In this research, we have performed a T-test to see how the relationship between dependent variable or visual point level and independent variable or visual quantity is in order to clear up the correlation between pattern of visual point and visual quantity by the constituents of a view from a different visual point level and the results are as follows: 1) In case of the character of Mt. Uam landscape of the city, Uamsan is set as a fixed point and about a direction of view(D), the north is a datum point from which the range of direction is distributed within 1800 westwardly and the visual range(R) is also within 2000m. An elevation is an average of 7.40 and the average story of the buildings is 3.85. Here the height of a story is about 4m so the average of the visual point difference is estimated at 15.4m. 2) The type of visual point is divided into the intersection group and the front of the highly used public buildings group. Double intersection types account for about 78.80%(52 spots) which forms a majority part of LCP. 3) The analysis of the difference of visual point level divided by eye level and that of the top of the buildings has been proved that there's a sharp difference resulted from t-test at 1 % significant level. The significant difference of elevation from height difference(l5.93m), however, has not been shown. 4) From the result of T-test about visual quantity by the elements of a view from a different visual point level, the visual quantity of mountain(VQM), sky(VQS), ground(VQG) is significant at about 1% each and that of building(VQB) is at about 5%. The difference in visual quantity of a mountain by the visual point level is at about 4% which can meet a marginal level of LCP necessary for evaluation of mountainscape.

  • This research was to find out the effectiveness of the horticultural therapy program based on the therapeutic factors and the most meaningful experiences of the clients. For this purpose "Green harmony" program focused on harmony through horticulture was implemented. It is based on the preposition that holistic health is promoted with harmonious relationships with oneself, other people, community and nature. The program has three-fold structure: In innermost it deals with the task of the late adolescent, i.e., self identity, secondly the experience of communication and solidarity in the group, and finally extension of interest to the community. For the therapeutic intervention, questions using the metaphor of the activity were given to the clients for the establishment of self-identity, while group activity and the donation of the works let the second and third purpose accomplished. Outdoor activity, 'Tire garden project', has provided the clients with chances of the contact with nature, cooperation with other group members, and a contest to provoke enthusiasm. Also recycling and greening of the community were possible by utilizing old tires for the containers and by donating the final works to the community. For the evaluation of the result, the effect of the program on the stress of the college students was tested, and the most meaningful experiences during the participation to the program were asked to identify the therapeutic factors acknowledged by clients. "Green harmony" program has brought positive effects on the stress of the clients in spite of relatively short period of five weeks. The clients has acknowledged plant/nature contact and interactions between group members for the most meaningful experiences. This research suggests "Green harmony" horticultural therapy program based on the therapeutic factors is highly applicable for the general populations.
