Construction and urban development projects that drove urbanization were perceived as a main culprit that disturbs environment and ecosystems, including urban heat island, air pollution and a decrease in species diversity in urban area, as they do not consider natural environment and adopt consistent development behaviors and rapidly degrade the ecology of development sites. In order to build a sustainable green wall system, design process is configured as follows based on basic technology development direction, climate environment elements, climate design technology elements suggested earlier. Each part of required technology element is codified systematically and a sound Korean-style green wall system design direction will be suggested.

When the revegetation of the slopes is required, it is more desirable to consider it from the ecological view point rather than from the disaster-preventive one because the environment is critical for the introduction of pioneer plants to the denuded slopes. The ecological point of view adheres to the maintenance of the present, original ecosystem of the construction area. The new revegetation technology is presented using native microorganisms and its effective usuage was discussed based on the data in the research field. Direct seeding is recommended and explained in detail than planting seedlings. The importance of inclination angle of slope face is shown for the successful revegetation from its relationship with the thickness of soil. It is indicated that the introduction of pilot plants to the slopes should include their ability to ease the acid rain effects as much as possible. Finally every construction may not be desirable for the maintenance and improvement of the global ecosystem without the consideration of the opinions mentioned above.

For artificial ground greening construction without root-proofing layer, this research reviewed the effect on watertightness of asphalt waterproofing layer by plant roots penetration based on crack width, and crack penetrated roots. Experiment on concrete crack width was performed with three conditions such as 0.15, 0.30, and 0.45 mm, and all three conditions confirmed that all plant roots penetrations were made through crack area in 12 ~ 18 months. In addition, according to evaluation of effects on waterproofing layer by crack penetrated plant roots and in condition of 0.45 mm crack width, it indicated that penetration is made on asphalt waterproofing layer in 12 months due to roots penetration.

The demands about eco friendly space are increased as buildings are denser in downtown, and green system on the roof and the artificial ground are widely being applied. The construction of green system applies a waterproof layer, a root barrier and a protection concrete layer. Assembly of these many layers leads to a long construction term, and cause many defects. This study is to evaluate one layer-hybrid sheet which gets waterproof and root barrier performance simultaneously, which is developed to use in the new green system. As results, the performances of physical properties, durability, waterproof and root barrier not only exceeded quality standards but also showed excellent durability. In addition, mock-up test would be proceed to certify long term performance.

Recently, a self-camera that generates and distributes a large amount of moving images has been rapidly increasing due to the appearance of SNS such as Facebook, Instagram, and Tweet using mobile. In particular, the amount of SNS connections using mobile phones is significantly increasing in terms of usage, number of connections, and usage time. However, the use of a self-recording system using a smartphone by itself is extremely limited not only in terms of usage but also in frequency of use. In addition, the conventional unattended recording system is a very expensive system that automatically records and tracks an object to be photographed using an infrared signal. Therefore, this paper developed a low cost unmanned recording system using mobile phone. The system consists of a commercial mobile camera, a servomotor for moving the camera from side to side, a microcontroller for controlling the motor, and a commercial wireless Bluetooth earset for video audio input. And it is an unmanned automation system using mobile, and anyone can record image by self image tracking.

The purpose of this study is to analyze the characteristics of limited methods, economics and breeding appropriateness of native and imported ground cover plants in the methodology of a shallow soil rooftop garden. The new shallow soil rooftop gardening method uses a total of 13cm in soil thickness, including 4.5cm of top soil on a 7.5cm rock-wool-mat stacked onto a 1cm roll-type-draining plate. The total construction cost for each method of soil level within the design price standard for SEDUM BLOCK is 89,433won/$m^2$, and for DAKU is 92,550won/$m^2$. By comparing those two methods, the construction cost of the shallow soil artificial foundation methodology is 45,000won/$m^2$; this shows the new method is 50% less expensive than the existing method of shallow soil rooftop gardening. The experiment was executed on the rooftop of the Korean National Housing Corporation to ensure validity of the shallow soil artificial foundation planting, and the sample plants which were imported and grown now in native covering. A list investigating the growing plants was made of the cover rate in each plant class, both while alive and the dry plant weight. The native ground cover plants, Sedum kamtschaticum, Sedum middendorffianum, Allium senescens, Sedum sarmentosum, Aquilegia buergariana, and Caryopteris incana increased the cover rate, live weight and dry weight in the shallow soil artificial foundation method. Among the imported cover plants, Sedum sprium and Sedum reflexum, the cover rate increased and growth conditions improved. However, some species needed weed maintenance. After examination with the less expensive shallow soil artificial foundation method and growth analysis, it was found that rooftop gardens are a low-cost option and the growth of plants is great. This result shows the new method can contribute to the proliferation of rooftop gardens in urban settings.

The serious consequences of the roadside erosion and its impact on sedimentation and deterioration of roadside landscape continue to be documented in Koreas. An analysis on the landscape conservation treatments was made through the field survey for the 8 radial roadsides around Seoul area. This was performed to identify and evaluate the present restoration measures, and to establish the practical standard measures for the landscape conservation treatments on the cut-and banking roadside slopes.
