Art Furniture is a terminology of creative and developed activity related Art in the field of furniture design. In a broad sense, the extent of Art furniture reaches from humanities to technology because Art includes them. Due to Postmodernism, designers who were involving Art furniture started to fuse various studies including high technology to achieve their own goals. To illustrate with the characteristic of high technology, I compare between low technology and high technology. Even though high technology are used both commercial furniture and Art furniture, the latter has been utilized high technology in a more creative and experimental way to develop experimental furniture design. In contrast, in order to earn economic profit, there is no unnecessary risk for commercial furniture. Considering information revolution which is deeply related with high technology, Art furniture designers could get information easily about other fields and make multiple connections of different kinds of people and markets. As a result, a combination between Art furniture and high technology has distinctive features. At first, high technology was applied to craft among Dutch furniture designers. After that, designers began to lay out the method of high technology and pushed the boundary of Art furniture thanks to experts and scientists. In addition, there was a designer who have conducted a series of research as a scientist adopting scientific methodology. In doing so, Joris Laarman could obtain a revolutionized work which could contribute society. In conclusion, combining Art furniture and high technology leads the definition of design from deciding physical shapes to directing and organizing processes.

The principle of energy dissipation technology is to dissipate or absorb the seismic energy input through the deformation or velocity change of dampers installed in the main structure of high-rise buildings, so as to reduce the seismic response of the buildings. With the development of energy dissipation technology, recognized as an effective and new measurement for reducing seismic effects, its application in high-rise buildings has become more and more popular. The appropriate energy dissipation devices suitable for high-rise buildings are introduced in this paper. The effectiveness of energy-dissipation technology for reducing the seismic response of high-rise buildings with various structural forms is demonstrated with a number of actual examples of high-rise buildings equipped with various energy dissipation devices.

The trend of the plasma cutting and laser cutting technology of metal alloys including high strength steel, aluminum alloys for the welding structures has been studied. The high-precision plasma systems offer a denser, higher energy arc that in effect produces a sharper cutting tool and high quality cutting products. The high-quality fiber laser systems with compact design and easy set-up make it ideal for cutting in the pipeline or steel structre manufacturing. This paper covers the scientometric analysis of the high efficient cutting technology which are based on the published research works in the 'plasma and laser', and 'cutting technology' obtained from Web of Science, and deals with the details of the background data of the plasma cutting and laser cutting technology.

Due to the development of the urban economy, high-density buildings and skyscrapers have continued to increase in order to alleviate high population densities and to make efficient use of urban space. However, a fire in a high-rise building is a disaster that can lead to massive casualties and property damage because of the difficulty of firefighting and escaping. Various studies have been conducted on these high-rise buildings because they are sympathetic to these difficulties all over the world. In this paper, trends of researches and technologies related to fire in high-rise buildings are analyzed synthetically through thesis and patent data. In other words, we explored the trends of various studies that have been carried out so far through the thesis, and performed technical monitoring on actual implemented technology and newly implemented technologies through patent data. Through this research, we have studied the present and the future of technology for high-rise building fire.

We have developed new reflective LCD for Mixed twist nematic LC mode with high quality image. We have found out an optimal twist angle of LC and optical film's axis by simulation. Also we measured electro-optic characteristics for new design panel. As a result, high reflectance and wide viewing angle characteristics were achieved.

Recently, high-entropy carbides have attracted considerable attention owing to their excellent physical and chemical properties such as high hardness, fracture toughness, and conductivity. However, as an emerging class of novel materials, the synthesis methods, performance, and applications of high-entropy carbides have ample scope for further development. In this study, equiatomic (Hf-Ti-Ta-Zr-Nb)C high-entropy carbide powders have been prepared by an ultrahigh-energy ball-milling (UHEBM) process with different milling times (1, 5, 15, 30, and 60 min). Further, their refinement behavior and high-entropy synthesis potential have been investigated. With an increase in the milling time, the particle size rapidly reduces (under sub-micrometer size) and homogeneous mixing of the prepared powder is observed. The distortions in the crystal lattice, which occur as a result of the refinement process and the multicomponent effect, are found to improve the sintering, thereby notably enhancing the formation of a single-phase solid solution (high-entropy). Herein, we present a procedure for the bulk synthesis of highly pure, dense, and uniform FCC single-phase (Fm3m crystal structure) (Hf-Ti-Ta-Zr-Nb)C high-entropy carbide using a milling time of 60 min and a sintering temperature of 1,600℃.

High temperature size exclusion chromatography (SEC) has been used widely for the characterization of crystalline polymers, for which high temperature operation above the polymer melting temperature is required to dissolve the polymers. However, this high temperature operation has many advantages in SEC separation in addition to merely increasing polymer solubility. At high temperature the eluent viscosity decreases, which in turn decreases the column backpressure and increases the diffusivity of the analytes. Therefore, many reports on the high temperature operation of high performance liquid chromatography (HPLC) have focused on shortening the analysis time and enhancing the resolution. However, the application of high temperature SEC analysis to exploit the merits of high temperature operation is scarce. In this article, therefore, we report on a new apparatus design for high temperature SEC.

본 연구는 기술보증기금의 기술평가자료를 활용하여 고성장기업의 결정요인에 대하여 분석하였다. 본 연구가 기존 연구와 다른 점은 3가지이다. 첫째, 현재 고성장 기업이 아닌, 향후 고성장기업으로 성장할 기업의 결정요인을 분석하였다. 둘째, 고성장기업을 매출과 고용 2가지 측면에서 각각 구분하여 분석하였다 즉, 매출증가와 고용창출에서 모두 고성장을 달성한 경우, 고용창출 측면에서는 고성장을 기록했지만 매출증가 측면에서는 저성장인 경우, 그리고 매출증가만 고성장을 달성하고 고용창출은 저성장을 기록한 경우의 세 가지 유형으로 구분하여 분석하였다. 셋째, 기술보증기금 기술평가모형(KTRS)의 기술평가지표를 설명변수로 적용하였다. 분석결과, 기술의 수명주기상 위치가 적절하고 기술의 완성도가 높을 경우에는 향후 매출과 고용이 모두 고성장하고 있다. 기술인력관리가 잘 되는 기업은 고용측면에서는 고성장을 하지만 매출측면에서는 오히려 저성장하고 있다. 이러한 결과는 고용고성장기업이 주로 기술인력관리가 중요한 하이테크산업에서 발생될지도 모른다는 추론을 가능케 한다. 이에 하이테크산업 여부를 나타내는 더미변수를 추가하여 분석한 결과, 하이테크산업에 속한 기업은 고용고성장의 가능성이 높은 것으로 나타나 이러한 추론을 뒷받침하는 결과를 보였다.

Numerous lead compounds, based on multipurpose privileged structures, can be generated that address a variety of targets from a gene family of interest, irrespective of therapeutic area. Solid-phase organic synthesis has been emerged as a powerful technique in generating combinatorial libraries of small organic molecules useful for drug discovery. Heterocyclic compounds provide scaffolds on which pharmacophores can be arranged to yield potent and selective drugs and a variety of heterocycles have been synthesized on solid support. (omitted)
