FM screening has been praised for its apparent resolution advantage over conventional AM screening. FM screening is also known for its criticalness of film output and difficulties in the proofing stage because of the microdot formation. However, FM screening is not a well understood process from press performance point of view. This study was carried out for the purposes of introducing the availability of hifi-offset printing to domestic printing industries and evaluating the print qualities between 300lpi AM screen and FM screen with the equivalent sized microdots to 4-5% dot area of the 300lpi AM screen, together with comparing with 175lpi AM screen representing a conventional printing. Solid density, dot gain, color gamut and some other quality properties were measured and discussed.

The measurement and evaluation of an audience's visual attention are crucial processes for the scientific production of various contents and services. It has been alleged that a vector exists between objects on a screen, but this has not been explored empirically. This study tested whether or not there are any positive correlations between screen vectors and viewers' eye movements. Participants were exposed to four groups of pictures representing an independent vector, continuing vector, converging vector, and diverging vector. The results showed that vectors on screens induced viewers' eye movements to the vector object by the directivity of the visual stimuli.

In this paper, we present a rotating auto-zeroing offset cancellation technique, which can improve the performance of touch screen sensing circuits. Our target touch screen detection method employs multiple continuous sine waves to achieve a high speed for large touch screens. While conventional auto-zeroing schemes cannot handle such continuous signals properly, the proposed scheme does not suffer from switching noise and provides effective offset cancellation for continuous signals. Experimental results show that the proposed technique improves the signal-to-noise ratio by 14 dB compared to a conventional offset cancellation scheme. For the realistic simulation results, we used Cadence SPECTRE with an accurate TSP model and noise source. We also applied an asymmetric device size (10% MOS size mismatch) to the OP Amp design in order to measure the effectiveness of offset cancellation. We implemented the proposed circuit as part of a touch screen controller system-on-chip by using a Magnachip/SK Hynix 0.18-µm complementary metal-oxide semiconductor (CMOS) process.

The purpose of this study was to fed out the effects of sensibility elements and screen composition elements on purchase intention on the internet fashion shopping mall. A total of 200 responses were collected from a Questionnaire survey. The sensibility words were used for sensibility elements analysis. Screen composition elements were divided into 5 factors by factor analysis; product property, convenience of shopping, service, design, and promotion. The study showed that the satisfaction of sensibility elements and screen composition elements led to a positive purchase intention.

Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

Mobile internet access using such devices as PDAs and cellular phones becomes popular as mobile technologies grow. However, the characteristics of small screen devices such as small screen size and pen-based input cause many usability problems. In this study, a human factors experiment was conducted to identify the factors affecting the usability of information search on a PDA. Factors manipulated in the experiment included use of wheel equipment, scroll dimension, and screen orientation. Task completion time, error frequency, and subjective satisfaction level were measured. In addition, various users' behavioral patterns such as scanning routes and mainly used scrolling methods were analyzed. Scroll dimension has a significant effect on task completion time. Scroll equipment and screen orientation affect subjective satisfaction level. The results could be applied to designing information structure of web sites for mobile use by providing vertical scroll and using external scroll equipments.

본 연구에서는 중국의 대표적인 탄막 동영상 사이트인 비리비리(Bilibili)를 중심으로 미디어 노출 신체이미지와 탄막의 이용이 다이어트 의도에 미치는 영향을 살펴보았다. 20대 중국인 여성 310명을 대상으로 온라인 실험 연구가 진행되었으며, 3 (탄막 여부: 탄막 없음 vs. 신체이미지 칭찬하는 탄막 vs. 신체이미지 비판하는 탄막) x 2 (미디어 노출 신체이미지: 이상적 vs. 현실적) 피험자 간 설계로 이루어졌다. 주요 연구 결과를 살펴보면, 이상적인 신체이미지를 칭찬하는 탄막과 현실적인 신체이미지를 비판하는 탄막에서 시청자의 다이어트 의도가 더 강하게 나타났다. 더 나아가, 시청자의 다이어트 의도는 현실적인 신체이미지를 탄막 없이 볼 때보다 이상적인 신체이미지를 탄막과 같이 볼 때, 그리고 현실적인 신체이미지를 비판하는 탄막을 볼 때보다 이상적인 신체이미지를 칭찬하는 탄막을 볼 때 더 강하게 나타나는 것을 확인하였다. 이러한 연구 결과는 사회적 시청의 방식 중 하나로서의 탄막의 이용과 수용자의 행동 의도에 미치는 영향을 이해하는 데 도움이 될 것이다.

In this study, theoretical super screen vibration analysis has been carried out to predict the dynamic characteristics of interactive waste particles. In order to approach these problems, it is necessary to have a fundamental understanding the screening process and the process of both the remaining and the passed material on a screen with several interacting screen planes based on Soldinger(1999) was discussed. Here, the vibrating screen is composed of three assemblies such as screen, wastes guide, and supported screen as shown in Fig. 1. This model is regarded vibrator as the system of screen fixed tilt plates. Then materials(or particles) of different size is to be separated by using the eccentric vibrator and classifying tilt plates. As well moisturized construction wastes is more efficient to separate than moisture-less it. In processing separate mechanism, the more materials is light, the more staying time is long. Thus much lighter construction wastes(wood, Styrofoam, etc) and heavier materials are separated by staying time delay in a super screen. The design results, separation screen were able to know that small and larger particles are conspicuous difference each motion character according to trajectory particles, and small particles raise the probability in classifying tilt plates.

스마트 디바이스의 개발과 발달, 그리고 스마트 디바이스의 보편화에 따라 사용자들은 한 개 이상의 스마트 디바이스를 소지하게 되었다. 기존의 온라인 학습 서비스는 하나의 스크린을 분할시켜 다양한 정보를 제공해 왔다. 그러나 기존의 PC환경과 다르게 스마트 디바이스가 발달되고 보편화됨에 따라, 사용자의 학습공간은 하나의 스크린 환경에서 다중스크린 환경으로 변화할 것이다. 본 논문에서는 다중스크린을 기반으로 한 스마트 학습공간을 구성하고, 스마트 학습공간에서 미디어 콘텐츠를 융합하여 서비스하는 시스템을 제고하고자 한다. 이에 다중스크린 관련연구 분야와 다중스크린 환경에 합당한 온라인 학습 서비스를 분석 설계하여 Timed Button이라는 스마트 디바이스 간의 동기화 기법을 제시한다.
