This study aims to develop a set of criteria for evaluating the sustainability of forest landuse, which could facilitate the environmentally friendly development of forest lands in Korea. The concept of sustainable development in forest landuse was reviewed from literature and by interviews with experts in forest-related fields. Delphi technique was employed for gathering experts' opinions. According to the results of Delphi test, the concept of sustainable development in forest landuse was confirmed as "Use of forest lands in a lasting manner within the carrying capacity of the ecosystem involved". There are 16 factors which should be considered with care when the development of forest lands is planned. They include the ratio of forest cover left undeveloped, ecological stability, and landscape naturalness. Among them are the ecological factors rated most important. The experts emphasized the importance of local characteristics in setting up the criteria for sustainable forestland development. The study did not attempted to apply the criteria to real settings. Therefore, before applications in real situations, further case studies should be made for the criteria to be safely used in landuse planning.

To restore urban water cycle, it is necessary to improve domestic laws and regulations related to LID(Low Impact Development), which has been successfully applied to foreign countries. Thus, this study has intended to evaluate domestic legal systems related to space and environmental planning and to suggest directions to improve laws and regulations related to space and environmental planning toward extended application of LID in Korea. To reach this goal, this study has analyze the legal and institutional status of the foreign countries where LID has currently been applied, to derive the factors that laws and institutions are required to support LID based on the above analysis, to evaluate domestic laws and regulations related to space and environmental planning, and to suggest directions to improve the laws and regulations. After the evaluation, this study has found the following results. First, it was found that the concept and basic principles of LID and LID planning and associated methods were no longer mirrored in the space planning-related laws and regulations. However, these problems are not confined to LID, and result from thefailurein applying environmental planning to space planning overall. Second, it was revealed that the environmental planning-related laws and regulations defined the terminologies and targets of LID and suggested different measures to improve LID-related policies differently depending on the backgrounds ofenforcing thelaws and regulations and on environmental properties. Finally, this study has suggested the directions to improve laws and regulations related to space and environmental planning as follows. First, it is necessary to enact a law to support the extended application of LID. Second, the law to be enacted should be connected to laws, enforcement ordinances and regulations, and guidelines related to space planning. Third, environmental benefits provided by both structural and non-structural techniques of LID should be quantitatively measured.

In the tall building construction, the slab formwork largely impacts on construction cost. Because productivity of a slab formwork is influenced by a number of and the efficiency of equipment, using the equipment-based construction method, an appropriate equipment input planning is crucial for the productivity. Meanwhile, the general equipment input planning is conducted by intuition based on experience due to the lack of equipment productivity data. Thus, this study develop a simulation model to analyze table formwork productivity and to propose an optimum equipment input plan that reflects the construction process, based on the full consideration of the economic factors. This study developed a simulation model by using CYCLONE and the data for the model was collected by measuring the duration of each unit activity in the tall building where table forms were applied. It is expected that a simulation model helps users to make better decision on the equipment input planning of slab formwork.

In this paper, a hybrid semi-3D path planning algorithm combining Virtual Tangential Vector(VTV) and fuzzy control is proposed. 3D dynamic environmental factors are reflected to the 2D path planning model, VTV. As a result, the robot can control direction from 2D path planning algorithm VTV and speed as well depending on the fuzzy inputs such as the distance between the robot and obstacle, roughness and slope. Performances and feasibilities of the suggested method are demonstrated by using Matlab simulations. Simulation results show that fuzzy rules and obstacle avoidance methods are working properly toward virtual 3D environments. The proposed hybrid semi-3D path planning is expected to be well applicable to a real life environment, considering its simplicity and realistic nature of the dynamic factors included.

This study aimed to identify the aquatic and riparian factors associated with the presence/absence of the Eurasian otter in the Nakdong river basin, where the species is relatively more abundant than other otter species. Environmental factors and presence records were collected. Geographical Information System technology and chi-square test were used to compare environmental gradients in aquatic and riparian factors between presence and absence sites. Aquatic habitat attributes were evaluated with natural riverside sandbars and channel crossing artificial structures, the ratio of channel width to alluvial plain width, riverbed substrate, and flow diversity. Riverbank characteristics, bank materials, man-made embankment types, and land use/land cover of inland and riverside areas were selected as riparian habitat attributes. Compared to the aquatic attributes, riparian attributes were highly significant when assessing otter presence and absence sites, suggesting that conservation of suitable riparian areas to provide maternity and resting areas for otter species is essential in the Nakdong river basin. None of the aquatic attributes examined were statistically significant when evaluating otter presence or absence. These results indicate that the presence of suitable riparian area for resting and reproduction habitats is more critical to the presence of Eurasian otter than food availability in aquatic areas. To inform implementation of effective conservation actions, broad-scale factors, such as watershed attributes, would be needed to further assess habitat conditions of the Eurasian otter.

This study is a qualitative case study aiming at understanding and finding out influential factors and barriers when school teachers choose Environmental Education as their Creative Discretionary Activities. To do this, this study focuses on the process of two teachers' choices of the Creative Discretionary Activities in two other elementary schools. The results of this research are follows. Two teachers' choices are affected by several influential factors, divided into external factors and internal factors. External influential factors include culture of school and education, media, chief education officers, parents and school. Internal influential factors are teachers' value and philosophy of education, teachers' experiences, teachers' capacity. These influential factors' forces aren't the same with each other. These influential factors, are influenced by educational, social, national, local, and school level indicated by Taylor et al's (1974) classification criterion. Especially, however, Korea's particular educational environment focusing on university entrance examination strongly affects teachers' choice. School factors also has a big strong effect on teachers' choice. Among others internal actors are the most serious influential factor affecting on teachers' choice.
