본 논문에서는 가상공간 협업 환경의 현실감을 향상시키는 초고해상도 타일드 디스플레이에 기반한 촉감 협업 시스템을 다룬다. 먼저 고해상도의 화면과 촉감 (힘)의 디스플레이를 조율하는 기법을 제안하고, 가시화 측면에서 제안 시스템을 모델링하여 성능 평가하는 기준을 제시한다. 그래픽으로 구성된 가상 환경이 힘에 대한 정보를 반환하기 위해서는 햅틱 렌더링을 처리해야 하고, 이 렌더링은 1kHz 이상의 속도로 반복되어야 한다. 또한 그래픽 환경의 고해상도 화면 출력을 위해서는 적정 수준의 프레임 율을 제공하여야한다. 하지만 시스템의 하드웨어적 성능은 제한되어 있기 때문에 두 프로세스를 안정적으로 실행하기에는 한계가 있다. 따라서 초고해상도 타일드 디스플레이에 기반한 촉감 협업 시스템의 안정적인 동작을 위해서는 자원의 효율적인 사용이 필요하다. 따라서 본 논문에서는 통합 시스템의 안정성 향상을 위하여, 효율적인 고해상도 디스플레이 방법을 제안함으로서 고해상도 디스플레이의 자원 요구량을 감소시킨다. 제안된 기법은 가시화 대상 화면을 가상 물체를 기준으로 분할하여 타일드 디스플레이로 전송함으로써 분할된 그래픽들을 독립된 프레임 율로 조절할 수 있도록 한다. 각 가상 물체 별로 프레임 율을 조절할 수 있게 하면, 움직이지 않는 물체에 대해서 업데이트를 줄여 전송되는 데이터의 중복성을 효과적으로 줄일 수 있다. 마지막으로 제안된 효율적 디스플레이 방법의 성능을 평가하기 위하여 일반적인 가시화 시스템의 모델링을 제시하고, 제안된 기법과 기존의 다른 가시화 시스템들의 성능을 비교한다.

The purpose of this study is to examine the effect of the fashion shop display on the clothing purchase made by the sample of 369 adult women living in Seoul area. In this study, the interest and the effect of the display are investigated through such factors of demographic variables as each individual's age, educational career, vocation, average family income a month, and marriage status. And the relationship is also examined between the person's interest paid on the display and the clothing attitude related variables of fashion follow tendency, individuality, and the way of practical economy. An additional examinations are performed in the first reactive factor to be considered at the time of the clothing purchase, and the interrelation between the discontent after purchase and the effect of display before purchase. The major findings of this research, thus, can be summarized as following: 1. Demographic variables of women reflect differences in their interests toward display and accordingly the variety of the display effect as well. Less interest and effect are caused by the effort of display for the women in their senior age. However, a group of the character women and young college women pay relatively more attention to the display and give more effect to the purchase. The examination shows alsp that the unmarried and better-off and better-educated are more sensitive to the effect of the display. 2. The higher is the individuality and the fashion follow tendency, the stronger revealed the interest in the display, while the economic women have less interest in it. 3. The first factor considered at the time of purchase is not absolutely affected significantly by the degree of the display effect in real purchasing act. 4. The discontent after purchase is not related with how much the degree of display effects in the act of real purchase.

The capacitance-temperature (C-T) measurement technique is proposed in the present work to investigate the thermal stability of organic and polymeric thin films for organic electroluminescent display (OELD). The single layer devices with the individual materials were subjected to the C-T measurement, prior to the examination of the complete OELD. The single layer devices with the small molecules destroyed below $180\;^{\circ}C$ depending on the kinds of materials. However, the device with the hole-transporting polyimide did not show any relaxation up to $200\;^{\circ}C$. The small molecule based OELDs failed to emit light after annealing, whereas that with the hole-transporting polyimide worked well in spite of large reduction in intensity.

Objective: The objective of this study was to examine frame ratio of text information and font size in the circle smartwatch. Background: Recently, electronic manufacturers try to develop the original metaphor of traditional wrist watch (circle) in terms of smartwatch. They endeavor to break the square display in order to improve emotional customer satisfaction. Method: The experiments examined twenty level of text information design, combinations of four frame ratios (1:1, 4:3, 16:9, 21:9) and five font sizes (6pt, 7pt, 8pt, 9pt, 10pt). Nineteen participants volunteered for the experiment. Dependent variables were WPM (Words per Minute), reading preference, design preference and total preference. Furthermore, small circle display was made by using circle display data (1.3inch), which was exhibited in IFA (International Funkausstellung) 2014. Results: As a result, ANOVA (Analysis of Variance) revealed that WPM, and task time preference affect the specific frame ratio and font size. Results of ANOVA for reading preference, design preference, total preference were grouped by post-analysis LSD (Least Significant Difference). Among users, display ratio (16:9, 21:9), and font size (9pt) were preferred. In conclusion, 16:9 display ratio and 9pt are adaptable for text information in 1.3inch circle display. Conclusion: From the study, it is shown that 16:9 display ratio and 9pt size are more adaptable for text information in 1.3inch circle display than others. It is mainly due to the fact that the order of frame ratio and font size may affect the usability of reading long text information in a small circle display. Therefore, when developers design a circle display, the square frame ratio and font size are required to be considered according to circle size. Application: The 16:9 display ratio and 9pt font size may be utilized as a text information frame in the circle display design guideline for smartwatch.

The contrast of display is one of the important specifications. Even if the contrast indicates luminance range which is a capability of the display and is greater in lower luminance or higher luminance, we consider that the greater contrast gets not the better performance. It is not the same value in human visual system. In practice, it is difficult to achieve the full dynamic range seen by human beings using electronic equipment. Therefore, we consider ambient condition and human perception to calculate perceptual contrast using the CIECAM02. In this paper, we propose perceptual contrast that is calculated using the brightness of CIECAM02.

In recent years, new materials and technology has been developed using single-walled carbon nanotubes (SWCNTs) as an alternative to indium tin oxide (ITO) to fulfil the requirements towards novel technological drive. These technologies offer products having a broad range of conductivity, excellent transparency, neutral color tone, good adhesion, abrasion resistance as well as mechanical robustness. In addition, SWCNTs can be solution processed to replace the sophisticated vacuum techniques at high temperatures. In the present work, transparent conducting films were fabricated from the purified SWCNTs. Dispersion of purified SWCNTs was accomplished in 1,2-dichlorobenzene without using surfactants or polymers following ultrasonic process. We achieved coating of nanotubes film on poly ether suiphone (PES) for an average sheet resistance ~110 ${\Omega}/{\Box}$ of optical transmittance 80% at 550 nm. Conventional spin coating method was followed to fabricate films from the purified and dispersed nanotubes solution. The results will be presented.
