The purpose of this study was to analyze the customer demand for design development of digital convergence furniture in the living space of the ubiquitous home. This study used the individual survey method and was collected from July 1 to 20, 2008. The frequency and percentage were used for data analysis by SPSS window's 12. The results of the study were as follows: The first, a lot of survey targets were 30-40 years old, university graduates, over 50,000,000 won in annual income and 30-40 pyung in house size. The second, what types of activity were carried out in the living room were acquisition of knowledge>entertainment activity>communication activity>household chores. The third, what types of furniture were used in the living room were A/V furniture>table>sofa>computer table>bookself. The forth, customers preferred to picture telephone service in sociality, home-theater service in entertainment and home appliances remote control service in information service. The fifth, the digital functions which can integrate with the living roon furniture, in the item for A/V furniture, was front door control function which recognizes visitors with the screen. In the item for table was function to search internet and for sofa was self purification function. Finally, the digital convergence furniture is not only for one activity but also for various types of activities that can comprehensively function to materialize the concept of comfortable furniture in the living space.

As various materials and new methods can be used due to developments in science and expansion of thinking, modern architectural color composes extensive possibilities exceeding its physical role of the past. In particular, rather than the initial external expression, the secondary connotative interpretation is more important in interpreting architectural color. This is because color interpretation changes the meaning of space based on light. Also, the development of digital technology has shifted the use of architectural color from passive realization to a more proactive concept and value. In other words, such shift leads to a new discussion on architectural color such as non-representation, invisibility, and non-physicality as the concept of fixed time, space and movement has been weakened. This paper begins by conceptualizing the digital space, a term widely used to interpret the architectural color of digital space. And it will be categorized as non-representational architectural color, invisible architectural color, and non-physical architectural color, by combining the characteristics of digital space with the modern architecture's color examples. Digital space overcoming the space time is differently interpreted from the past color expression. Modern architecture's color which substitutes the passive view with active body takes a role delivering various axes of discussions with synaesthesia.

The purpose of the weapon live test during the phase of development is to provide essential information to decision makers that verify and validate the performance capabilities of weapons. Due to varying allocation and high variance of test resources with an increase in the weapon system's capability, the test environment can get highly complex, which can lead to a decrease in the reliability of test results. This issue can be addressed by applying a decision support system that provides various timely information collected by resources during the test process. The decision support system can be designed by applying the concept of digital twins, that are defined as digital replicas of components, systems and processes. This paper describes a design methodology of the decision support system that consists of digital models and service functions using digital twin architecture. A case study illustrates the feasibility of the proposed methodology in supporting the weapon live test process.

Purpose: Evidence-based design is the process of making design decisions based on reliable research to achieve the best results, so it is important to accumulate reliable evidence through research. Therefore, the purpose of this study is to present new evidence by applying the evidence-based design process to improve the digital signage for each room spaces in hospitals and verifying its effectiveness. Method: Through the 8-step process of evidence-based design, improved digital signage for each room spaces are installed. It conducted surveys and statistical analysis to prove hypotheses by linking design and research. Results: The hypotheses established in the study are: 1) improvement in the readability of digital signage is correlated with patient satisfaction; 2) Improving the intuitiveness of digital signage correlates with patient satisfaction; 3) Improving the sufficiency of digital signage correlates with patient satisfaction. As a result of satisfaction analysis and correlation analysis, all of the above hypotheses were proven. Implications: Although the hospital sign system is the element that patients rely on most intuitively in the long journey of reception, waiting, examination, and treatment, there is insufficient evidence to refer to or apply it when designing. It is necessary to expand future research to expand the evidence that can be applied to hospital sign design.

디지털 스토리텔링은 콘텐츠와 메시지를 전달하는 효과적인 방법으로서 디지털 체험 공간에서 인간과 디지털 콘텐츠 그리고 공간과 인간 간의 상호작용을 유발시키는 커뮤니케이션 전략으로서 활용되고 있다. 본 논문은 디지털 체험 공간속에서 활용되는 디지털 스토리텔링을 살펴보고 이를 통해 유발되는 상호작용을 논의하는데 목적이 있다. 이를 위해 우선 인식론적 차원에서 디지털 체험 공간에 구현된 디지털 콘텐츠와 디지털 스토리텔링에 대해 살펴보았으며, 디지털 체험 공간의 공간 스토리텔링을 논의하였다. 또한 디지털 체험 공간의 능동적 주체인 사용자가 디지털 스토리텔링을 통해 유발되는 상호작용성과 감각적 체험을 논의하였다. 마지막으로 디지털 체험 공간 '판교 아이큐아리움'에서 활용되는 디지털 스토리텔링과 공간 스토리텔링 그리고 상호작용 요소를 분석하였다.

마이크로프로세서를 사용하여 디지털 방식에 의해 온도보상을 하는 버스트 모드 광송신기를 구현하였다. 기존 실시간으로 신호를 처리하는 아날로그 방식의 온도보상 방법에 비하여, 본 연구에서 구현한 디지털 방식의 온도보상은 신호를 샘플링 처리함으로써 고속 버스트 모드 광신호를 효과적으로 처리할 수 있다. 온도보상을 위한 디지털 자동전력조절 방식은 데이터 전송속도에 영향을 받지 않을 뿐만 아니라, 아날로그 방식에 비해 보다 정확하고 효율적이므로 Gb/s 이상의 고속 버스트 광신호 처리에 유용하게 사용될 수 있다.

Musculoskeletal disorders(MSDs) are one of the major issues in shipbuilding industry. Main risk factors of MSDs include manual handling of heavy weight, awkward posture, repetitive tasks, prolonged static muscle contraction, and so on. in this study, Using the three-dimensional digital human modeling and simulation method we made up a worker and work posture on a virtual environment. To verify this simulation we compared both traditional ergonomic analysis on a real worker and digital program analysis on a digital human. And this paper shows that it is possible to reduce the rate of MSDs in the shipbuilding industry because it means we can change poor posture mid surroundings into better ones.

The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears. There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer. It`s way to help in architectural design and wishes.
