Since the cognitive science developed as a brandl of academic researdl, studies on human brains have flourished. Emotional features have been centered on the field of design, and the development of the design process has been diversified that makes use of the factors. The purpose of this study is to reflect the current trend and to convert the results into a method for designing. The researdl is based on the mind map techniques which spread like a trendy fashion, and tries to supply a theoretical explanation of how to overcome the fixed idea. Recognizing the importance of learned information in approaching a problem, I regarded the roles of left and right brain as analogue and digital images interpreting them by freely crossing language(digital images) and visual thought (analogue images), using mapping tedlniques. I pursued the research goal of the techniques focusing on the idea of using mapping. As a result of this. I established a logic system [figure 8] in that a proposition which starts as a problem introduction goes on until a problem solution, which is visualized with concept presentation, using a brainstorming technique. According to the suggested concept. I concluded that idea proliferation as a design demand can be solved by applying mapping techniques like one shown in figure 12.

Recent construction projects have now regenerated the existing city rather than reconstruction or redevelopment to create a new paradigm. While the aged houses are reviewed to distinguish between the repair, reinforcement and reconstruction stages, the modular construction system makes the most of space using the modular system, and the projection mapping system is combined with the existing space. Therefore, we will proceed with the research so that improvement and correction of future issues can be made.

Recently, scanning projects have been carried out in various construction and construction fields for maintenance purposes. The point cloud generated by the scan results is composed of a number of points representing the object to be scanned. The process of extracting the necessary information, including dimensions, from such scan data is called paradox. The reverse engineering process of modeling a point cloud as BIM involves considerable manual work. Owing to the time-consuming reverse engineering nature of the work, the costs increase exponentially when rework requests are made, such as design changes. Reverse engineering automation technology can help improve these problems. On the other hand, the reverse design product is variable depending on the use, and the kind and detail level of the product may be different. This paper proposes the G2BM (Geometry-to-BIM mapping) rule definition method that automatically maps a BIM object from a primitive geometry to a BIM object. G2BM proposes a process definition and a customization method for reverse engineering BIM objects that consider the use case variability.

A Technology Roadmap (TRM) is extensively used as a tool to manage activities of researching and developing technologies and products that can help a business achieve its goals. However, most of past studies on TRMs have limited themselves to developing in a single product or a single industry level. Few research studies have examined how TRM are used for convergence products and services for future development. The aim of this chapter is to introduce a TRM development methodology for u-City technologies and to consider its possible application at the R&D program level in Korea. This research suggests ways to develop a TRM in u-City development by segmenting u-City technologies, projecting TRM for each technology and designing TRM templates for evaluating both current and future technologies. In addition, the study further highlights to prioritize which technology is favorable for the implementation based on its economic feasibility and technological maturity.

오늘날 모바일 시장을 중심으로 다양한 플랫폼이 등장하면서 모바일 어플리케이션 개발 시 여러 플랫폼을 고려해야 하는 부담이 증대되고 있다. 이러한 상황에서 Model-Driven Development(MDD) 는 멀티플랫폼에 대응하는 어플리케이션 개발의 효율성을 높여줄 수 있다. 하지만 이 기법을 이용하는 대다수의 연구 결과들은 해당 방법론을 통해 생성된 결과물의 질을 객관적으로 평가할 수 없고, 이 때문에 해당 방법론의 성능 평가가 힘들다. 본 연구에서는 대상 플랫폼들이 제공하는 API 를 분석한 결과에 근거하여 공통 요소를 추출하고 이를 이용하여 MDD 기반으로 개발을 진행할 수 있는 개발 프로세스를 소개하고, 이를 통해 생성된 소스 코드의 기능적 유사도 및 코드 생성률과 기능적 유사도를 평가할 수 있는 방법을 제안한다. 이 방법은 코드를 AST 로 바꾸고 API 맵핑 테이블에 근거하여 동일한 키워드로 변환하고 유사도를 측정하여 설계 시 의도한 기능이 얼마나 잘 코드로 생성되었는 지 평가할 수 있는 방법이다. 본 연구에서는 이 방법을 이용하여 생성된 코드의 기능적 유사도와 코드 생성률을 측정하였다.

This work examines discourse on uses of computer technology and its transformation during the last thirty years effecting Korea landscape architecture. First, in the 1990s landscape architects begun to use computers as a new technology for landscape architecture, programming computer software utilities suitable for landscape research, planning, and design. The landscape architects, acting as computer programmers, tried to explore various techniques for landscape analysis and design with a piece of software, and various experts within the field of landscape architecture collaborated with each other. However, landscape architects mainly used computer technology as a tool as a substitute for hands-on cases. Since around the 2000s, the discourse on mapping and diagrammatic techniques as a visualization technique for landscaping processes have begun. Also, realistic representations for perspective drawings using graphic software have been increasingly important. The landscape architects, acting as graphic designers, focused on the specific visualization techniques for landscape planning and design. However, computer technology has been mainly used to produce realistic visuals aids for final presentations instead of creative exploration to generate landforms. Additionally, recent landscape architects have been using landscape performance modeling and parametric modeling for landform and landscape furniture design. The landscape architects as spatial designers are actively using computer modeling as creative form-generating tools during the design process.

Pavement crack sealing method, which is one of the methods to maintain and repair the road, prevents the extending of cracks by repairing cracks in its early occurrence and has already been applied to many roadworks in advanced foreign country for a long time. But in the conventional crack sealing method, traffic accidents occur frequently during the repair because it's commonly performed on the heavy traffic road or highway. It also has some difficulties in securing the safety of workers from the risk of burns caused by heated sealant. In an effort to solve these problems, automated pavement crack sealing machines such as ARMM, OCCSM, TTLS have been developed in advanced foreign country since early 1990s. Also APCS in 2004 and ACSTM in 2013 were already developed domestically. However, since these automated crack sealers developed from a number of research institutions have different test-bed conditions and productivity measurement models, it's difficult to compare and evaluate them objectively. In this study, the image processing time of the respective machines and the movement time of each motion on the work process were estimated by using fully autonomous mapping and semi-automatic mapping in order to measure the productivity in the same environmental conditions. In addition, the productivity measurement test-bed reflected domestic road characteristics was designed to estimate and compare the productivity of the automated crack sealing machines.
