Blogs that allow two way communications are open to the public more than 20 million sites these days. The study tries to categorize and classify blogs based on the common representative factors. As blogs are changing dynamically, the study also tries to figure out key factors either for growing or perishing dynamics. The study develops the research idea from the independent variables such as contents factors and psychological factors to the controlling factors such as trust, attitude, and purchasing intention. The research found out that opinion leading and information seeking tendency are significantly related to the attitude to the internet shopping mall.

3D contents could cause unique 3D visual fatigue. Screen disparity, image blurring, and crosstalk are known to be the three major factors responsible for the fatigue. Among these, screen disparity and image blurring are content factors, that is, one can directly manipulate contents themselves to handle visual fatigue caused by these two factors. On the other hand, because crosstalk is closely tied to physical characteristics of 3D display, it is difficult or even impossible to reduce crosstalk-driven visual fatigue unless one replaces 3D display itself (for example, from active to passive display). However, the effects of crosstalk on 3D visual fatigue depends on visual stimulus features (that is, contents), and thus it is possible to manipulate stimulus features in order to handle visual fatigue caused by crosstalk. Hence, this research tested the effects of visual stimulus features on crosstalk (which then causes 3D visual fatigue). Using relative depth discrimination task, we tested the effects of stimulus-background contrast, background texture density, and screen disparity on the degree of perceived crosstalk. The results showed that crosstalk decreases with presence of background texture and with less degree of screen disparity.

The purpose of this study was to investigate the influential factors of space marketing, and then to empirically analyze how they were reflected on the facade elements of sports stores. In order to achieve such a purpose, the research was firstly based on the perspective of space marketing to extract various features into 4 types of factors, namely sensuous factors, differentiated external appearance factors, image-associating factors and story-creating factors. Secondly, this study extracted the elements of facade design for sports stores including architectural elements, visual elements and display elements. Thirdly, it clarified the correlation of the influential factors of space marketing with the external space elements of sports stores. Fourthly, the qualitative analysis method was applied to analyze eight selected cases in Busan and eight selected cases in Fukuoka, Japan in order to explore the various different methods of expression of facade design. Lastly, the study found that the stores in Busan mostly take advantage of contrasting effects to deliver a strong visual impression to customers in the sensuous factors. Besides, the facade shapes in Busan were designed to be straight in order to enhance the main doors with its distinguished formative features to maximize the effective expression of the differentiated external factors, along with other expression methods of the image associating and story creating factors. This was done to associate with the brand identity in comparison with the stores in Fukuoka.

The temperature distribution of a glass plate heated in the infrared heating chamber has been investigated. Temperature of the glass panel is measured using a set of thermocouples and the optical pyrometer. Temperatures measured by thermocouples have good agreement with those by the pyrometer. The temperature uniformity of the panel is improved with wall reflectivity, which is one of the important factors to uniformly heat the panel

Parametric studies are performed of the factors influencing the afterbody drag. To display the effect of differing afterbody shapes, several ogive boattails with combinations of the base area and the angle of boattail end are computed using axisymmetric Navier-Stokes equations with central differencing and a DADI scheme. And Chien's $\kappa-\epsilon$ model is employed used for computations of turbulent flows around the base region. The effects of base area, boattail angle and jet on/off are illustrated on afterbody drag at transonic speed.

Xe content is one of important factors related to characteristics of the mercury-free flat fluorescent lamp. The electro-optical properties of lamp were investigated for wide range of Xe content in Xe-Ne mixing gas. The maximum luminance of $9,289\;cd/m^2$ and efficacy of 3 lm/W was obtained with Xe 90 %.

We will discuss encapsulation of OLEDs on both flexible and rigid glass substrates. Accelerated testing at 6CC/90RH and 85C/85RH is compared and acceleration factors for OLED and Calcium test samples are discussed.We have tested the stability and performance of our barrier coating to much higher temperatures: up to 140 C. Water Vapor Transmission rates at temperatures from 60 to 140 C are presented. Rates and methods for low cost manufacturing on a large scale are analysed

In this talk, the general concept of roll-to-roll printing technologies will be introduced with basic fundamentals of ink formulations for printing electronic devices as the first part of the talk. As the second part, based on the R2R printing process, key factors for printing TFTs, IC, PV and display would be presented using the information from the case study of R2R gravure and offset.

We studied the properties of vapor flux distributions of nozzle shaped thermal evaporation sources and the factors, which can change the flux distributions such as nozzle structure. We used a simulation and experiment methods for this study. By using the results of our study, we improved the Circular Nozzle Source, which can make uniform thin films without substrate rotation, into more efficient source.
