오픈소스가 소프트웨어의 영역을 넘어 그 개념이 여러 분야로 확장되어감에 따라 여러 기업들이 오픈소스 개념을 이용한 비즈니스 모델을 등장시키고 있다. 본 연구는 3D프린터를 활용한 웹 기반 오픈소스 플랫폼 제작 방안에 관한 연구로서 키덜트 문화를 접목시킨 사용자의 자발적 참여도가 높은 오픈소스 플랫폼 커뮤니티 제작을 목표로 한다. 연구방법으로는 여러 기업의 오픈소스 활용 사례에 관한 분석 연구와 더불어 키덜트 커뮤니티의 사용자 설문을 통해 플랫폼의 사용성과 토이 디자인 선호도 및 성향 분석을 기반으로 한 기초 자료 수집을 통하여 초기 플랫폼 제작 방향성을 설정하였다. 제작된 플랫폼에서 고유의 플랫폼 토이 소스를 다운로드 후 사용자가 자유롭게 재해석하고 플랫폼에 결과물을 재공유하여 완성된 디자인의 선호도에 따라 판매하여 수익을 분배할 수 있도록 하는 것이 특징이다. 향후 플랫폼 내 커뮤니티를 활성화하여 사용자의 진입동기부여를 높이는 연구가 지속하여야 할 것이다.

After the industrial revolution, interior of living space have shifted from the spacial structure of existing wall partitions to visually and spacially continuous open space. And these open space can be recognized mostly in the common space of housing architecture of living, dining, and kitchen space composition. In order to understand the characteristics of space and compositional method, the works of Le Corbusier, W. Grupius, and F.L. Wright in their living, dining, and kitchen space design have been analized from the collected materials to make evaluation for the similarities and significance of their space compositional factors. therefore, this study is to analize space composition and design factor of the modern housing space of Living, Dining, and kitchen space variation and character of open space design factor for the practical use as an index of designing contemporary living space.

In recent years, numerous studies have attempted to extract quantity data by using Building Information Modeling (BIM). In terms of open-BIM based quantity take-off at the early design stage, only few studies were conducted in the field of cost engineering. A lack of compatibility of open BIM for information exchange is postulated as the cause. The Industry Foundation Classes (IFC) extension model has been developed to accommodate the interoperability with quantity take-off software. Improvement of open BIM for quantity take-off needs exchange requirements and model guidelines. For this purpose, the quantity data of IFC models were analyzed using BIM analysis tools. This paper also provides a proposal of requirements on open BIM based quantity take-off at the early design stage. Further this study have been develop the interface system for open BIM based quantity take-off requirements with the results on this study.

Open-cell silicon foam is difficult to cut using conventional machining processes because of its low stiffness. That is, open-cell silicon foam is easily pressed down when the tool is engaged, which makes it difficult to remove the material in the form of chip. This study proposes an advanced method of machining open-cell silicon foam by freezing the material using liquid nitrogen. Furthermore, the machining conditions are optimized to maximize the efficiency of material removal and minimize the usage of liquid nitrogen by conducting experiments under various machining conditions. The results show that open-cell silicone foam products with free surface can be successfully machined by employing the proposed method.

In this age of "Information", many people consider it a deterrent to information flow to provide a hierarchy with private rooms in a modern office layout. There are others, however, who insist that visual and acoustical privacy are more important than any other design factor in achieving higher productivity. The debate may never end, but the partitioned open plan, which is a new form of the vast open plan, has merits of each concept - open and closed layout. Consequently, office design has dramatically shifted to partitioned open planning, with shorter, temporary walls or partitions, originally intended for increasing privacy and diminishing hierarchy, yet still keeping flexibility in spatial organization. The introduction of low-level partitioned spaces in an office layout, however, produces a complicated lighting design problem. Obviously, accurately predicted daylighting performance data are needed not only for daylighting design but for artificial lighting system design. Scale models of 12 sets of unit partitioned spaces are constructed and extensive scale model measurements of both daylight and reflected sunlight have been performed within an artificial sky simulator. The prototype-building interior is modeled with different partition configurations, each of which is modeled using the different envelope geometry and exterior configurations, and then the variations in interior light levels are estimated. The result indicates that partitioned spaces employed in an open plan of modern offices still offer a large potential for daylighting and energy saving as well. Much of the savings may derive from the cumulative effect of reflected sunlight. Optimal design for building envelope geometry and exterior configuration promises additional savings.

This paper describes the design and implementation of a PC(personal computer) based open architecture machine tool controller. The hardware of open architecture CNC has generally a motion control board on a PC for controlling a servo motor. But this paper describes open architecture hardware that consists of a PC, a counter board a DAC board and a DIO board only. This makes it easy to generate CNC software module in a hardware-independent way. The proposed open architecture CNC software runs on the MS-Windows NT. The paper describes a method of con-trolling servo motors using a real-time timer of MS-Windows NT and a commercial real-time operating system on the MS-Windows. NT. An open and reconfigurable software module is made up of an object and an API(application programming interface). Using the object and the API a new CNC system can be quickly configured to control dif-ferent machine tools. The proposed open architecture CNC system is applied to 4-axis lettering center.

When applying geothermal systems in cities such as seoul where high density development prevails, the selection of geothermal system capable of obtaining a large capacity in the limited grounds is necessary. In this study, an easy-to-use design tool is developed in the form of spreadsheet by applying the calculation theory of existing closed-loop vertical ground heat exchanger that can be used in the early design stage of the open-loop ground heat exchanger. By only using the maximum cooling and heating load, it is possible to calculate optimal design open-loop ground heat exchanger. Further research is needed, we are plan to improve the program considering the heat loss of groundwater flowing in the inner casing, G-Function for Open-Loop, and verification by applying actual projects.

This study aims to provide basic materials for adaptive-clothing development for disabled seniors by considering the characteristics of design with both functionality and beauty, which is displayed to overseas functional clothing for disabled seniors. After 341 photographs from 15 overseas websites which sold adaptive-clothing for disabled seniors were collected, their designs were analyzed. The content analysis and frequency analysis using the descriptive statistics were performed as the analytical methods for this study. The results are as follows; first, the design of buttons uses snap fasteners, zippers, Velcro fasteners and rubber bands so as to attach easily and keep fasteners unseen. Second, the used open system is the Back open, the Side open, the Front open and the Hip open. Third, in terms of design, the change follows easy and loose silhouette in order to act comfortably outdoors as well as indoors by making the design of onepiece dresses, jackets and cardigans similar to ordinaries. From the details aspect, a few trimmings such as color, patterns, ruffles around edge, laces and smooth shirring do not stand in the way and give mental please.

The intent of this study is to investigate the current situations and planning implications of elementary schools in urban housing blocks, and to propose the planning and design guidelines for them. The premise of this research is that an elementary school should function as a communal facility, shared by its community, so called open-school. 32 schools in three new towns were selected as sample cases and they were closely surveyed in terms of their site planning issues in residential blocks, and three sample open-elementary schools were analyzed in a comparative manner for finding their roles and functional fulfillment as a communal facility in the neighborhoods. Based on the findings, several planning principles and design techniques or devices are suggested for the utilization of elementary schools by local residents, mainly making issues of location, relationship to other facilities and open spaces in residential blocks, access, apartment layout, school building and outdoor spaces, and open program.
