Recently, the elevator industry in Korea has been divided into the high speed elevator market and medium-low speed elevator market, and SMEs are making rapid progress in the medium-low speed fields. Usually, since the elevator manufacturer receives an order for installation after the construction of the building structure, it is necessary to promptly create a optimal elevator model and layout drawing in an earlier stage of sales activity due to the limited time to elevator installation. This study analyzes the sale and design works of the elevator SMEs, examines the areas that can be efficiently improved, and integrates the preceding our studies from the viewpoint of efficiency improvements at sales and design business process in the elevator industry. After that, we proposed an integrated framework of sales and design process for the elevator SMEs industry, and developed a prototype software system for automating the creation of optimal elevator model, layout drawing of elevator and BOM(Bill Of Material) list.

반도체와 LCD 산업 분야, 나노급 공정 및 검사 기술이 요구되는 산업 분야의 수요 증가에 따라 초정밀 가공/생산/검사 장비를 설치, 운용하는 FAB. 구조물의 설계 요구가 층증대 되고 있다. 이에 따라 건물의 환경진동 규제치도 강화되고 있는 실정이다. 이와 같은, 대형 구조물에서 서브마이크로 수준의 미진동(微振動)을 제어하는 문제는 여전히 어려운 과제로 남아 있다. 이는 진동 응답을 결정하는 구조와 재료가 복잡하고 다양한 형태를 갖고 있는 반면, 다루어야 할 동적 응답은 극한적으로 작은 마이크로(micro) 이하의 값을 다루어야 한다. 그러므로, 기존에 이용되고 있는 해석과 실험의 결과만으로는 신모델 설계에 적용하는 것은 어렵다. 따라서, 본 논문에서는 이러한 영역의 경험적 데이터물을 체계적인 데이터베이스로 구축하여 새로운 동적 구조 설계 기술의 기반을 제공하고자 한다.

In building-integrated photovoltaic (BIPV) systems, power generation functions are integrated into building functions by installing solar modules in combination with building materials. While this integration appears to be attractive, a design method is needed to achieve maximum power generation. Previously, the influence of the design elements on power generation was analyzed by computer simulations and demonstration tools. On the other hand, problems remain due to the inaccuracy of power generation analysis and relationship analysis, and limited demonstration. To solve this problem, this paper proposed the use of an extended demonstration mock-up. The mock-up was designed and constructed by implementing the design elements of the module types, installation angles, and direction. The actual operation data for one year were analyzed to evaluate the effects of the design elements on power generation. These results can be used to determine the feasibility of future BIPV systems and the optimal selection of system design elements.

Three dimensional urban models are being increasingly applied for various purposes such as city planning, telecommunication cell planning, traffic analysis, environmental monitoring and disaster management. In recent years, technologies from CAD and GIS are being merged to find optimal solutions in three dimensional modeling of urban buildings. These solutions include modeling of the interior building space as well as its exterior shape visualization. Research and development effort in this area has been performed by scientists and engineers from Computer Graphics, CAD and GIS. Computer Graphics and CAD focussed on precise and efficient visualization, where as GIS emphasized on topology and spatial analysis. Complementary research effort is required for an effective model to serve both visualization and spatial analysis purposes. This study presents an efficient way of using the CAD plans included in the building register documents to reconstruct the internal space of buildings. Topological information was built in the geospatial database and merged with the geometric information of CAD plans. as well as other attributal data from the building register. The GIS network modeling method introduced in this study is expected to enable an effective 3 dimensional spatial analysis of building interior which is developing with increasing complexity and size.

As the Korean government initiates the Han-style campaign, the efforts and expectations for the modernization and industrialization of Hanok are growing. Accordingly, a major R&D project sponsored by the government is in progress for the development of related technologies, in which the development of a Hanok design support system based on Building Information Modeling(BIM) technology is included as one of the major subjects. However, the development of design tools for Hanok so far has not focused on the windows and doors, which is another major element of Korean traditional architecture. Therefore, this study developed a BIM-based design tool for Hanok windows and doors as an approach to the integrated design of various Hanok elements and their applications to modern buildings. To this end, the characteristics of Hanok windows and doors were analyzed first in terms of the location, opening method, style, components, and the over-all construction. A design tool was then developed with the parametric modeling functions of the $ArchiCAD^{(R)}$system. The applicability and efficiency of the developed tool were verified with design simulations. This is expected to contribute to not only the application of Hanok windows and doors to modern buildings but also to the further development of an integrated Hanok design system.

Building Integrated Photovoltaic (BIPV) system is a typical integrated system that simultaneously performs both building function and solar power generation function. To maximize its potential advantage, however, the solar photovoltaic power generation function must be integrated from the early conceptual design stage, and maximum power generation must be designed. To cope with such requirements, preliminary research on BIPV design process based on architectural design model and computer simulation results for improving solar power generation performance have been published. However, the requirements of the BIPV system have not been clearly identified and systematically reflected in the subsequent design. Moreover, no model has verified the power generation design. To solve these problems, we systematically model the requirements of BIPV system and study power generation design based on the system requirements model. Through the study, we consistently use the standard system modeling language, SysML. Specifically, stakeholder requirements were first identified from stakeholders and related BIPV standards. Then, based on the domain model, the design requirements of the BIPV system were derived at the system level, and the functional and physical architectures of the target system were created based on the system requirements. Finally, the power generation performance of the BIPV system was evaluated through a simulated SysML model (Parametric diagram). If the SysML system model developed herein can be reinforced by reflecting the conditions resulting from building design, it will open an opportunity to study and optimize the power generation in the BIPV system in an integrated fashion.

In this paper we designed and implemented a wireless communication circuit which can control the remote devices integrating RFID and ZigBee. This system unifies transmit part and receive part. And this system recognizes RFID tag data, then the recognized information is controlled by MCU, and transmitted to a remote device through the ZigBee. This is operated on TinyOS. If this system is applied to a entrance security system, it can permit/deny one's entrance as well as control the personal computer or other electronic devices. Our experiment shows the result of the recognized data transmission is very different according to a opened playground and a closed place. The data transmission time is stable in the indoor and the data transmission distance is long in the outdoor. We anticipate that our system be applied the various office oriented domains by connecting to the Wired LAN or the WLAN of IEEE 802.11x category.
