These days, interior construction is performed to prevent the deterioration of old building finishings or to make distinctive designs. In case of interior construction, a construction cost is estimated through basic 2D drawings in the design step. Accordingly, an efficient construction plan and direction is established according to budget. In such a case, construction is dependent on 2D drawings. At that time, a risk can occur easily. This study is aimed at reducing the cost and risk of interior construction by implementing 3D drawings with the use of the visual data of 2D drawings. For accurate analysis, 2D drawings were completed, and then 3D interior construction modeling for various buildings was conducted with the 3D modeling software 3D Max. According to the 3D modeling, it reduced the cost and risk more than 2D drawings based design, and influenced the improvement in the understanding of orderers and workers.

For deciding the profitability and feasibility of the construction project, the schematic estimation has to not only link the design decision-making but also estimate the cost with reliability. The prototype-based schematic estimation system was developed for easily linking with design-making and supports to evaluate the design alternatives in the design development stage but didn't consider the cost estimated by parameter and additional work items by users. This research presents the object-parameter based schematic estimation model in the design development stage that can lead to accurately estimate the cost by using historical data from the high-storied office buildings. For the development of the proposed model for schematic estimation, after analyzing and classifying the work items from the Bills of Quantities(BOQs) and drawings of historical data, this research proposed the methods of estimating cost in accordance with attributes of each work item. In addition, a case study is performed for the effectiveness as comparing the previous estimating method with the proposed model.

Purpose: This study examines the daylighting design factors of Korean dementia nursing homes, in order to realize a therapeutic environment based on the therapeutic effect of light in the rapidly aging trend with an huge increase in the population of dementia in Korea. Methods: Through literature reviews, this study aims to theoretically examine the therapeutic light environment for the elderly with dementia, derive daylighting design factors of Korean dementia nursing homes, and analyze their detailed design factors. Results: The result of this study can be summarized into two points. The first one is that the daylighting design factors reflected in dementia nursing homes are derived into six factors: building layout, windows, glazing, shading devices, spaces, and interior finishings that determine the availability of daylight. The second one is that the detailed daylighting design factors are shown as primary and secondary detailed design factors, and the main values to be considered when applying these factors into dementia nursing homes are analyzed as maximizing daylight availability, optimization of the possibility of therapeutic view, and anti-glare. Implications: The daylighting design factors will contribute to maximizing the availability of daylight, optimizing the possibility of view, and minimizing the glare in the living spaces of dementia nursing homes in Korea.

In Korea, there has been a tendency that multi-family housings are constructed by providers such as constructors or real estate agents for the economical benefits and selling efficiency, using standardized plans, load-bearing wall system, water-based construction method, and uniformized formworks. Especially, the traditional installation works which service equipments are buried into structures cause serious problems such as shortening building life span, increasing times of remodeling during specific period (100 years) and wasting resources. Also the unilateral way of massive distribution by providers for multi-family housings is not appropriate to meet the various social needs of residents. To solve these problems, it is necessary to build long-life housing which can be easily separated installations, interior and exterior finishings from structural parts. Therefore, this paper will examine the present administrative law and the civil law in order to find negative factors that can be obstructions for providing long-life housings and set the direction to revise the regulations.

Purpose: This study aimed to develop a daylighting design indicator for Korean dementia nursing homes based on the therapeutic effects of light, focusing on the serious aging index facing Korea and the importance of natural light that occupies the most important position in the therapeutic environments for the elderly with dementia. Methods: A wide range of literature-oriented research methods were mobilized to develop the daylighting design indicator of Korean dementia nursing homes. Results: The daylighting design indicator of Korean dementia nursing homes was derived from three perspectives: maximizing daylight availability, optimizing therapeutic view, and minimizing glare. In addition, eighteen basic indicators were derived within seven indicator items in the range of building layout, windows, glazing, shading devices, spaces, interior finishings, and daylight factor. Implications: The daylighting design indicator of Korean dementia nursing homes revealed in this study will contribute to realizing Korean dementia nursing homes as a therapeutic environment for the elderly with dementia.
