  • The toner type paper-like display (PLD) has been developed with two polymer particles having opposite polarity composed of polymer, colorant and external additives (nano-sized silica). Nano-sized silica with triboelectric charge was used for the charge control agent (CCA) and influenced on the electrostatic properties of the silica-coated polymer particles. The surface morphology and the cohesiveness of silica-coated polymer particles were changed with the silica coating time. From these results, it was verified that the PLD cell using silica-coated particles (200 seconds) shows a good white appearance and low driving voltage.

  • The several wearable devices are not able to communicate through cable due to its portability. The wireless communication method is used because of its good communication quality and group action features when the several wearable devices communicate with each other. In this paper, we proposed the group decision algorithm for grouping display of the several wearable devices. It means that recognize as a group member after measuring distance in the wireless communication environment. The result of experience showed that the group-type display of several wearable devices method overcome the limit of the display of single wearable device.

Effects of the Syllable Number, Font Type, Color Contrast, Display Type, Letter Size and Age Group on the Legibility of the Korean Characters (음절수, 폰트, 색 대비, 표시 형태, 글자 크기, 연령대가 한글 문자 정답률에 미치는 영향)

  • This study evaluated the effects of the syllable number(one, two), font type(gothic, myung), color contrast (black on white, white on black), display type(paper, LCD), age(20s, 60s) and character size(2~80pt) on the Korean characters' legibility. Total twenty subjects from two age groups (20s: n=10, 60s: n=10, five male and five female in each group) participated in the legibility test. A target panel was presented in the distance of 50 cm, and subjects conducted a reading tests for, in total, 16 treatment conditions (full combination of syllable number, font type, color contrast and display type). Results showed that two-syllable words revealed better legibility than one-syllable character. The main effects of the age, display type, font type, color contrast, and character size were statistically significant(p<0.01). Paper showed better legibility than LCD, particularly in the 20s and in the character sizes of less than 9pt. Gothic revealed more correct answers than Myung, particularly in the 60s, paper, and white on black conditions. It is expected that these results can provide basic data for the determination of the Korean characters' minimum legible size standards. For example, the minimum legible size for the Gothic and black on white characters presented in the paper should be 5pt for 20s and 1lpt for 60s if the 75% correct reading(3 correct answers in this study) was applied for the legibility criterion.

  • The first purpose of the present study is to investigate the way of displaying English words to facilitate phonological loops on the digital screen, and the second purpose is to test whether or not the more effective display type can increase learning rates equally in both low and high foreign language motivation group. To achieve these aims, two experiments were conducted. Experiment 1 showed that 3 times display condition generated higher performances in recall and recognition test than 1 time display condition did. In Experiment 2, we recruited high motivated group and low motivated group in foreign language learning, and assigned each member into 3 times display condition and self-pace condition. The results of Experiment 2 showed that the performance in the low motivated group was higher in the self-pace condition than in 3 times display condition, while this difference was not found in high motivated group. The present results suggest the display type increasing usage of phonological loops in digital screen environments.

Factors that affect consumer attitude by the types of show-window display and the difference by the gender of consumer (소비자 성별(消費者 性別)에 따른 의류제품(衣類製品) 쇼윈도우 디스플레이 유형(類型)에 대한 태도 요인(態度 要因))

  • The main purpose of this research is to examine what are the factors that affect consumer attitude by the types of clothing window display, and find if there is any difference by gender of consumer group. Total 357 data from random sample of 347 adults(156 male and 191 female) who were between 19 to 49 years of age were analyzed. Sources for the sample were companies and apartment complexes and several colleges in Seoul and Chonan to diversify by such demographics as age and social status. Factors were measured by respondents' rating of 9 statements using a 5-point Likert-type scale. SPSS(Statistical Package for Social Science) Version 10.0, is used for factor analysis in order to comprehend the factors of consumer attitude and Cronbauch's ${\alpha}$ in order to measure the credibility of questions in each factor. The main findings are as follows: First, three dimensions of consumer attitude to two types of window-display of product centered display and image centered display were identified as interest, information, and impression and theses are same to both male and female consumer group. Second, for both male and female consumer group, three dimensions of consumer attitude toward two types of window-display were same, however, included sub categories in each dimension showed a little difference. In product centered display, both male and female consumer group showed high interest in the sub categories of 'fashion' and 'informations related to the product' and they were considered same factor. Otherwise, In image centered display, two sub categories of 'having some interests in the display' and 'recognize the display that projects the image or impression of clothing well' were showed high relationship each other and they were also considered same factor. Third, Cronbauch's ${\alpha}$ of three dimensions of consumer attitude demonstrated high credibility from 0.75 to 0.91. Mean score of subcategories of attitudes toward the type of display by the gender of consumer showed high scores of 'interest' and 'impression' categories in image centered display and showed high scores of 'information' category in product centered display for both gender.

  • The purpose of this study was to investigate the actual state and problems of outlet stores. And examine store attributes shopping orientations information sources according to demographic characteristics for outlet store patronage group. The questionnaires were administered to 400 women living in Taegu. The data were analyzed by using Frequency Percentage Factor Analysis MANOVA. The results of the study were as follows; 1) Outlet stores in Taegu area were run as the type of agency and dealt in most brands of their own companies, There were plenty of as-sortment and merchandise. The discount rate was 50-60% Stores' locations were scattered which made shopping environment incon-venient. 2) The store attributes were composed of five factors such as fashion & products diver-sity service store reputation convenience and price. Shopping orientation were com-posed of six factors such as self-confidence for shopping brand oriented store loyalty & near-store oriented economical self-assumed shopping and difficulty of choice. Information sources were composed of four factors such as print media & display personal information advertising and store visit. 3) There were significant differences be-tween patronage group and non-patronage group in store reputation service fashion & products diversity. Patronage group is more satisfied with these three factors. There were significant differences between patronage group and non-patronage group in brand oriented and economical Non-patronage group was more brand oriented and patronage group was more economical. There were significant difference between patronage group and non-patronage group in print dedia & display factos. Non-patronage group made more use of print media& display than patronage group as information sources. There were significant differences between patronage group non-patrpnage group in age marital status and levle of education.

  • Pentacene moiety has been widely studied in Organic Thin-Film Transistor (OTFT) device as a channel layer because of high carrier mobility. In this study, we have fabricated vertical type Organic Static Induction Transistors (SITs) using pentacene, 6,13-Dinaphthalen-1-ly-Pentacene (1-DNP, 3), and 6,13-Dinaphthalen-2- ly-Pentacene (2-DNP, 4). 1-DNP and 2-DNP have same naphtyl group with pentacene, but different linked position and spatial arrangement. We have checked the static characteristics of materials in vertical type SITs device. We found that pentacene has as on/off ratio of 14.56, 1-DNP and 2-DNP shows as on/off ratio of 36.58 and 6.61 at VDS = 2V in SIT, respectively.
