Wood cutting utilizing CNC art in the field of furniture design industry, art, education are diverse. However, there is lack of data in the case for wood cutting, such as cutting conditions and wood cutting. So this article is to establish furniture design processing using CNC. The researchers investigated the processed products using CNC, the data of the web site and CNC relevant articles, then organized its impact on the furniture industry today. History and definition of CNC have studied for a discussion of the advantages and disadvantages. Then, the researchers analyzed the cases to investigate the wood cutting conditions, was applied to the fabrication of furniture domestic and foreign. CNC organized systematically design information through the computer So, it allowed to reduce the repetitive behavior that has to work hand in the furniture manufacture existing. CNC has made it possible to design a fine complex in furniture design industry. So it became possible to make a new representation and production of various forms. Material about CNC are mostly for milling machine and shelves for metal processing. So, the researchers investigated and precautions general content of wood cutting. The enhanced understanding to investigate an example that is applied outside the country, is used to analyze the expression various techniques CNC. It is difficult to obtain accurate data processing, it has various characteristics in the same timber, Future research is about analyzing type applications and CNC machining range at the time of processing the various wood.

This study aimed to develop organic design and propose references on an origin and developing factors of the organic design as looking into previous researches on furniture design. Expressive features with curves observed in the furniture design have been interpreted as organic meanings, and the study also approached grounds for the organic design elements while talking about developments of new materials and digital technology. In addition, the study presented a possibility explaining that these organic design elements might have been derived and developed from Art Nouveau. State-of-the art technology of the digital era in the 21st century has been built upon more creative concepts, and as this technology gets combined with the digital technology, it is, now, changing but also improving both morphological aspects and design methodologies. In the midst of this change, when it comes to factors to develop the organic design, creation of various new materials and state-of-the art digital technology are considered to be immediate factors to changes in the design. As morphological thinking using digital media develops, geometric thinking and such form are realized which eventually would lead us to furniture design of a new concept.

The purpose of this study was to evaluate the effect of asymmetric muscle force in lower extremity on dynamic balance during walking. Sixteen elementary students(age: 12.3±0.7 yrs, height: 149.4±9.7 cm, weight 40.6±7.8 kg) who have no musculoskeletal disorder were recruited as the subjects. Temporal parameters, M-L inclination angle of XCoM-CoP, M-L and A-P CoP, loading rate, and decay rate were determined for each trial. For each dependent variable, a independent-sample t-test was performed to test if significant difference existed between each conditions(p<.05). The displacement of antero-posterior COP during RTO-LHC1 in SG was siginificantly smaller than corresponding value in AG. In contrast, the displacement of medio-lateral COP during RTO-LHC1 in SG was greater than those of AG. It seems that imbalance of muscle force may result in increasing the medio-lateral stance in order to minimize the instability. We found that the asymmetric muscle force in the lower extremity may be a reason for the awkward control of impact force.

원자력발전소의 격납건물(Containment Building)내의 작업종사자들은 작업종사자들의 위치를 추적하여 작업자에 대한 관리가 필요하다. 격납건물(Containment Building) 내는 구역이 복잡하고 고 방사선 구역이 많으므로 작업종사자들이 불필요하게 많은 방사선에 노출될 수 있고 고소지역에서 작업하는 종사자가 작업중 위험한 상황에 처해 있을 경우 위험을 알리며, 위치를 파악하여 작업종사자들의 안전과 효율적인 관리가 필요하다. 본 논문에서는 원자력 발전소의 격납건물(Containment Building) 내와 같은 구조가 복잡하여 방해 전파가 심각한 실내 환경에서도 정밀한 위치측정 및 견고한 데이터 통신을 가능하게 하는 CSS(Chirp Spread Spectrum)를 이용하여 1차원, 2차원의 RTLS(Real Time Locating System)을 개발한다. 거리를 계산하는 알고리즘으로는 SDS-TWR(Symmerical Double-Sided Two-Way Ranging)를 이용하여 간접경로 문제를 해결하기 위한 방안을 제시하고 Ranging 거리를 늘리기 위하여 출력파워가 KCC 규격에 맞도록 10mW의 설계이득을 가지는 파워회로를 추가하여 개발하며, Anchor와 거리측정 컴퓨터간 통신을 CAN 통신을 사용하여 Tag(노드)들의 에너지 사용시간을 늘릴 수 있게 설계한다.

The invention and development of digital computer networks since the post-modern culture and creating new ideas, and in nearly all areas since the industrial revolution has had the greatest impact. A new paradigm for the 21st century, the Internet and ubiquitous, and mobile devices are being created by the new culture is being created. Rapidly being replaced by digital and analog, and 'Digilog' fusion concept has appeared. In addition, the development of computer cyberspace culture, art, design and structure are changing. In the field of furniture design, changing design processes and innovative design philosophy that change is now occurring. These symptoms experienced at the same time, almost every country on Earth is a phenomenon. Since the 20th century, computer network design based on the relationship between digital and cyber culture espoused by philosophers studied society and organic modernism and organic design of digital-based differences are confirmed through the case. Using digital technology, modeling case study of a furniture designer in cyber space and the creation of human capabilities and the fusion of computing power will be studied in modern furniture design.
