New liquid crystal (LC) host mixtures and reactive mesogens (RMs) designed for the Polymer Sustainable Vertically Aligned (PS-VA) mode have been developed. The novel combination of LC host mixture with RMs enables to show superior LC display performance with high reliability and to contribute for the robust LC panel production process.

Commercial conductive metal inks are available, but metals used in these have unsuitable work function for efficient OLED device performance. Metals with low work function tend to oxidize easily, which makes it challenging to develop low work function metal inks. In this research we describe printed low work function Al cathode.

Two-dimensional orthogonal variable spreading codes are presented for multiplexing of forward link in direct sequence code division multiple access (DS-CDMA) multiple antennas system And the results of code generation and simulation of 2 dimensional orthogonal variable spreading factors on Jacket matrices are also be investigated. The bit error rate(BER) performance under a multi-user environment for the additive white Gaussian noise (AWGN) channel demonstrated that the proposed scheme could provide flexible rates and lower correlation values

본 연구는 역경지수와 연구개발역량이 기업성과에 미치는 영향과 이 변수 간의 관계에서 조직창의성 영향요인의 매개역할을 분석하였다. 본 연구는 7개의 가설을 설정하였으며, 역경지수를 통제력, 영향범위, 및 지속성으로 구분하였고, 조직창의성 영향요인을 조직자원과 조직경영관행으로 구분하였고, 기업성과를 경영성과와 기술적 성과로 구분하였다. 본 연구는 경기도 소재 기술창업 중소기업에 근무하는 CEO를 대상으로 1,000부의 설문지를 배포 후 무기명으로 122부를 수집하였다. 응답이 불성실하거나 누락된 6건을 제외한 116부의 설문지를 가설검증에 사용하였다. 본 연구의 분석결과는 다음과 같다. 첫째, 역경지수 가운데 영향범위는 조직자원에 정(+)의 영향이 있는 것으로 나타났다. 둘째, 역경지수 가운데 통제력은 경영성과 및 기술적 성과 각각에 정(+)의 영향을 미치는 것으로 나타났다. 셋째, 조직경영관행은 경영성과에 정(+)의 영향을 미치는 것으로 나타났다. 넷째, 조직자원은 통제력과 기술적 성과 간의 관계를 부분 매개하고, 영향범위와 기술적 성과 간의 관계를 완전 매개하는 것으로 나타났다. 마지막으로, 본 연구는 연구결과의 이론적 시사점 및 실무적 시시점에 대해 논의하였다.

The resistance performances were studied for two 50-ft-class power yachts made of carbon fiber reinforced plastic (CFRP) with different hull form characteristics using model tests. The tests were carried out at a high-speed circulating water channel (CWC) for the 16–38 knot range. The total resistance, trim, and sinkage were measured, and the results were compared with wave patterns. The results showed that a chine position at the draft line had a strong effect on the planning performance and resistance performance in a certain velocity range.

We have proposed an Object-linked Broadcasting Service that displays various data related to the object onscreen. In thls paper, we describe the structure of the Object-linked Broadcasting System that will enable our proposal to be realized, and report new techniques that we have developed to create the system. We have carried out the experiment to confirm the system performance as well as execution of each technology assembling the system. We have confirmed that the performance of the system we developed satisfies the proposed specification based on user requirements and current technology.

This research attempts to acquire technical performance measure information based on identifying the Critical To Quality(CTQ) parameters of user requirement by using Quality Function Deployment(QFD) methodology in the initial phase of a defense R&D project. This results will contribute to the integration of technical progress to the Work Breakdown Structure(WBS) based project performance tracking. It also improve the bridging of systems engineering activities to the project management and the project decision making process.

Recently, from the viewpoint of global wanning, natural gas CO2 is considered as a main refrigerant for hot water system. The characteristics of CO2 is not toxic, not flammable, high pressure, and high refrigerating capacity. Also it is widely available as a byproduct of industrial processes. This paper describes the performance analysis program of the swash plate type compressor using CO2 refrigerant. Estimates of the refrigerant flow rate, compression work, discharge temperature and volumetric, compressor efficiencies of the CO2 swash plate type compressor are obtained from the various design parameter such as the inclination angle of the swash plate, discharge hole area and suction hole area.
