이 논문은 보육교사의 직무에서 정서표현규칙의 하위요인과 정서노동 수행전략 간의 관계 및 영향력을 알아보는데 목적이 있다. 이를 위해 서울 지역 어린이집에 근무하는 보육교사 268명을 대상으로 설문조사를 실시하였고, 자료 분석을 위해 상관관계 분석과 회귀분석을 실시하였다. 연구 결과 첫째, 정서표현규칙 지각은 정서노동의 내면행동, 표면행동과 유의한 정적 상관이 있는 것으로 나타났으며, 내면행동은 정서표현규칙의 교육, 몰입, 공정성, 명확성과 유의한 정적 상관이 있는 것으로 나타났다. 둘째, 정서표현규칙 지각은 표면행동, 내면행동에 정적인 영향을 미치고, 정서표현규칙에 대한 몰입이 내면행동에 유의한 정적 영향을 미치는 것으로 나타났다. 이러한 결과를 바탕으로 보육교사의 정서노동을 지원하고 교사의 정서관리 능력향상을 위한 교육방향을 제안하였다.

Writable Cholesteric Liquid Crystal Display and the algorithm used to detect its image were developed. We could use any hard tip, ex: the tip of a forefinger, to directly write an image on the surface of Cholesteric Liquid Crystal Display (CHLCD). By measuring the capacitance of one pixel of test cell (12mm x 15mm/1x1), F-state or P-state could be detected. By measuring the capacitance of one pixel of 4.1" CHLCD (241um x 241um/ 320x320), F-state or Pstate could not be detected, due to the effect of parasitic capacitance. Therefore, high frequency measurement and the algorithm were developed to detect the image on CHLCD.

We present simulations and results to demonstrate the viability of stainless steel foil as a substrate for low power consumption, flexible AMOLED displays. Using organic planarization layers, we achieve very smooth surface properties, resulting in excellent TFT performance, that can be repetitively flexed without significantly affecting device performance. The use of phosphorescent OLEDs enables the design of low power consumption 40" AMOLED displays.

Moire topography method is a well-known non-contacting 3-D measurement method. the automatic 3-D measurement by moire topography has been required since the method was frequently applied to the engineering and medical fields. 3-D measurement using digital projection moire topography is very attractive because of its high measuring speed and high sensitivity. In this study, digital two-wavelength phase shilling moire is applied to the entertainment fields. recently. as promoting the growth of the VR-Game, display devices which attract public attention such as HMD or Projector are being appeared in order to deliver effectively the absorption sense. this study realized the Auto-calibrating system for arbitrary display surface using digital moire method which satisfied the shape measurement of display surface and the request of FOV(Field of View) output. also when large screen wasn't prepared, this auto-calibrating system was applied to enjoy games or movies at home with a projector and walls

Recombinant Escherichia coli displaying organophosphorus hydrolase (OPH) was used to overcome the diffusion barrier limitation of organophosphorus pesticides. A new anchor system derived from the N-terminal domain of ice-nucleation protein from Pseudomonas syringae InaV (InaV-N) was used to display OPH onto the surface. The designed sequence was cloned in the vector pET-28a(+) and then was expressed in E. coli. Tracing of the expression location of the recombinant protein using SDS-PAGE showed the presentation of OPH by InaV-N on the outer membrane, and the ability of recombinant E. coli to utilize diazinon as the sole source of energy, without growth inhibition, indicated its significant activity. The location of OPH was detected by comparing the activity of the outer membrane fraction with the inner membrane and cytoplasm fractions. Studies revealed that recombinant E. coli can degrade 50% of 2 mM chlorpyrifos in 2 min. It can be concluded that InaV-N can be used efficiently to display foreign functional protein, and these results highlight the high potential of an engineered bacterium to be used in bioremediation of pesticide-contaminated sources in the environment.

In this paper, we describe a study on the influence of the frequency variation of normal vibration using an integrated tactile display. It is necessary to consider this study because we want to find a method of displaying finer texture and know that the perception of fine textures is heavily influenced by temporal variation. Our tactile display system used in this experiment can simulate the micro shapes and roughness of surface textures by individual drives of a 6x8 pin array. Two experiments are performed. The first is a psychophysical experiment on the definition and range decision of roughness, and through the experiment, we clear up the meaning of roughness. The second is the main experiment about the frequency variation of normal vibration. We find the correlation between the vibration frequency and the texture and the condition for better display and perception of fine surfaces. The experimental results yielded two pieces of information. One is that lateral movement affects texture discrimination, and another is that normal vibration can make the perceived texture feel finer than real texture. That is, the vibrating stimulus is more effective for displaying a fine surface than static pressure, and it makes possible to display finer texture, exceeding the physical limit of the device.

유비쿼터스 컴퓨팅 기술들의 발달로 인해 인터랙티브 디스플레이는 사용자에게 다양한 인터랙션을 제공하고 있다. 이러한 인터랙션을 위해 다양한 방법들이 연구되었지만 디바이스 사용성과 단일 사용자에게 제공된다는 한계점이 발생하였다. 따라서 본 논문에서는 앰비언트 디스플레이 환경에서 다수 사용자에게 다양한 인터랙션을 제공하기위한 공간 멀티 인터랙션 인터페이스를 제안한다. 이를 위해 적외선 LED 배열바(IR-LEDs Array Bar)를 통해 사용자가 인터랙션 할 수 있도록 인터랙션 막을 생성한다. 이때 사용자는 인터랙션 막에서 공간 터치를 통해 다양한 인터랙션을 경험할 수 있다. 따라서 휴대 디바이스 없이도 사용자의 자연스러운 손동작만으로 인터랙션을 할 수 있는 인터랙티브 디스플레이 시스템과 인터페이스 방법을 제공한다.

In this work, we evaluated the Al₂O₃ film, which was deposited by atomic layer deposition, degraded by exposure to harsh environments. The Al₂O₃ films deposited by atomic layer deposition have long been used as a gas diffusion barrier that satisfies barrier requirements for device reliability. To investigate the barrier and mechanical performance of the Al₂O₃ film with increasing temperature and relative humidity, the properties of the degraded Al₂O₃ film exposed to the harsh environment were evaluated using electrical calcium test and tensile test. As a result, the water vapor transmission rate of Al₂O₃ films stored in harsh environments has fallen to a level that is difficult to utilize as a barrier film. Through water vapor transmission rate measurements, it can be seen that the water vapor transmission rate changes can be significant, and the environment-induced degradation is fatal to the Al₂O₃ thin films. In addition, the surface roughness and porosity of the degraded Al₂O₃ are significantly increased as the environment becomes severer. the degradation of elongation is caused by the stress concentration at valleys of rough surface and pores generated by the harsh environment. Becaused the harsh envronment-induced degradation convert amorphous Al₂O₃ to crystalline structure, these encapsulation properties of the Al₂O₃ film was easily degraded.
