Purpose: Korean society has already entered an aged society but there aren't many evidence-based studies on the elderly-friendly design elements in the apartment environment, which is the main residential type in Korea. The main purpose of this study is to verify the necessity and expandability of the outdoor environment design in the public rental apartment complex through the evaluation of the effectiveness and satisfaction of SMG(Seoul Metropolitan Government) Cognitive Health Design Project in GR 1 apartment complex. Methods: The research subjects were GR 1-complex as experimental group and the nearby Wolgye Deer 1-complex as control group, both public rental apartment and located in Seoul. As a research method, the survey was conducted before and after the implementation of SMG project for residents of the apartment. A total of 200 preliminary surveys and 203 post surveys were conducted. Results: As a result of this study, residents' accidents related safety have decreased, and both the frequency of use and satisfaction of most facilities have increased. It is noteworthy that the increase in cognitive items in the post-survey. Also, 74.5% of the residents evaluated that the complex was better to live after the project was implement. Implications: The fact that the preliminary surveys were not conducted for the same person is considered as the limitation of the study, but it is meaningful in that it systematically assesses the effectiveness of the project on the cognitive health of the outdoor residential environment towards age-friendly city.

The drone photogrammetry is actively utilized for obtaining highly accurate spatial information and other various monitoring purposes. It is general to plan the drone photogrammetry by referring to previous experiences or cases in order to obtain the required accuracy, but the drone photogrammetry is often carried out again due to poor accuracy. Since the required spatial accuracy of the drone photogrammetry process result becomes the means of objective evaluation regardless of the type of result, it should be determined carefully. Therefore, it is necessary to determine flight height, overlap, number and arrangement of ground control point, and exterior orientation factor acquisition method in order to meet the required 3D positional accuracy for the design of drone photogrammetry project. In this study, previous study cases for the analysis of drone photogrammetry accuracy were carefully analyzed and verified by applying such cases to testing area, and design guideline of drone photogrammetry project for a small area was prepared based on the analysis result. The presented project design guideline is expected to be a great help to business practice although it is not perfect, and if the design guideline is prepared through comprehensive analysis in future, it would be possible to provide a perfect manual.

The objective of this research is to develop a knowledge discovery framework which can help project teams discover useful patterns to improve energy efficient building design. This paper utilizes the technology of data mining to automatically extract concepts, interrelationships and patterns of interest from a large dataset. By applying data mining technology to the analysis of energy efficient building designs one can identify valid, useful, and previously unknown patterns of energy simulation modeling.

The objectives of this research are 1) control of schedule or improvement of management for aerial environment, 2) distribution of responsibility to the parties concerned (factory, material company, construction company, design and engineering, occupancy). The results show the relative priority of the four major items in wall-based apartment buildings and in column-based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows more efforts to improve IAQ are needed in material factories and engineering/design companies.
