In this study, clinical data for emmetopia in young Koreans was taken in order to design the finite schematic eye, which had optical properties of real eyes including spherical aberration, astigmatism, field curvature and distortion. Furthermore, the crystalline lens with GRIN medium was optically analyzed, and the finite schematic eye with the GRIN crystalline lens was designed.

This paper aims to analyse design conditions and propose schematic design for Galhyeon Elementary Middle School in Gwacheon. As for site conditions, it has the size of $32,000m^2$ and Hilly areas. And the area is surrounded high density housing. As a program, Education Facilities Bureau required to provide 36 classes and supporting facilities. To design the schemes, we followed the 7th education policy guidelines. During the design development stage, 3 alternatives are suggested as in the paper. However, staffs of Education Bureau and teachers favoured and selected our scheme, which gives symbolic image, as a new high school education environment.

The construction industry has been evolving with the development of information technology. According to this trend, the current industry changes from 2d drawings to Building Information Modeling(BIM). Current studies on the BIM-based estimation have problems such as Quantity Take-Off(QTO) specificity toward a particular software, the uncertainty of the amount in accordance with the model quality. These studies focus on QTO based on BIM rather than schematic estimation. In addition, studies on the connection with the QTO and unit cost for schematic estimation are insufficient. The purpose of this study is to propose schematic estimation process by utilizing construction codes and QTO in architectural object BIM libraries. Construction codes are classified in detail in order to input codes inside each. This study has connected unit cost and construction classification codes that obtain from BIM model. The results of this study will be helpful in decision-making and communication for schematic estimation of the design phase. It will improve the efficiency and reliability problems of existing schematic estimation.

This paper describes the geographical and cultural characteristics of Han river and presents a schematic design of outdoor lighting for Han river bridges. Basic design concept for Han river and detail theme for each bridge was developed. With lighting simulation program, lamp, color, and image of bridge in Han river modeled and simulated. Lighting visualizations of the three major bridges were shown and detail design concept for such bridges were introduced.

This study is intended to suggest methodologies in theory that is dedicated to improve existing features in BlM tool sets and introduce a new horizon for developing new features in the future so that more functionality can be provided to the work process of architect. To be more utilized of BlM tool sets in a useful way, it is important to make sure to program a calculation method used in the design process which is based on the information provided by architect, such as design item with detailed process and transformed parametric information on warranty data. Finding pros and cons in the usability from the well-known 3D modeling applications and taking highly usable UI features from the existing applications, and using a common wording were carried out. Design architect identifies reusable parametric information and then finds an algorithm between each items so that BlM tool sets can contribute to design field in the future. Therefore, the formula has been developed for the items considering business aspects and architecturing size in the preliminary-design, and design aspects in the schematic design with idendifying inputs and outputs that is necessary to become fixed factors.

This study has revisited the definition and characteristics of BIM to contribute to the better understanding of this concept. For the successful application of BIM in architectural design field, it should start with public buildings like schools which can be standardized. Since a number of conditions of school design appear to suit the schematic design phase for BIM application more than do other types of building design, the viability of BIM was examined by applying parametric modeling(one of BIM's basic characteristics) to mass study in schematic design phase for the configuration of schools that adopt the variation type of subject classroom design of the $7^{th}$ National Educational Curriculum. In addition, this modeling technique was used with software of Rhino 3D and Grasshopper, which will have a linkage to environmental analysis in near future. Finally, it can be expected that the work efficiency will be maximized if BIM is going to be applied in the early design stage instead of the end stage.

In spite of various approaching method to satisfy with the owner's requirements in schematic design phase, it is insufficient to evaluate intermediate process of design arithmetically with participating in design process. So the numerous changes of design after completion of design development cause a lot of loss to the design company. The designer arranges owner's requirements to prevent from this loss at the initial stage of schematic design phase systematically and lets owner and stakeholder to evaluate the value of schematic design to satisfy with owner's and stakeholder's requirements. If the evaluated value for schematic design is above a definite value index, the next design phase should be advanced. By this method, the design company can reduce the additional expenses remarkably by preventing with re-design which is occurred by not reflecting owner's intention or by changing owner's intention. Also the designer have the owner to evaluate the result of design and construction. The designer let the owner know whether the owner's requirement should well have been reflected on drawing or not. There is a strong point to be able to minimize the criticism which can be occurred after completion of construction by evaluating for owner's satisfactory degree and by having owner and designer confirm the result of design and construction arithmetically. This paper presents that the loss of design company can be minimized by going over at next step if the value is over a definite value index after evaluating value for each design from design process.

When managers predict exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But present of public construction cost estimation and management almost after the construction documents design phase. Therefore, construction cost management in the early stage and schematic design phase to generally use approximate estimating is not correct. Accordingly, this study analyze problem of current cost estimating method and a concrete cost plans make using case information of actual cost to analyze in schematic design phase. Possible to check going on the suitable design, this study conducts the preliminary research for the development of cost estimating model.
