Print mottle is the spotty and cloudy appearance of the ink on the substrate. Print mottle is influenced significantly by the characteristics of the paper with regard to homogeneity of its structure and its coating. The print mottle can be counteracted, in particular by altering the absorption characteristics of the inks, by changing sequence in which the inks are printed, or by using a advanced coated paper. In this study, we investigated the effect of ink dispersion to the print mottle through trial printing test and also analyzed the correlation between properties of coated paper and subjective results by statistic method. The result of this study is expected to be applied the basic data to solve the problem of printing mottle.

For Romantic women writers the paratext itself is essentially a masculine literary space affiliated with established writing practices; however, this paper suggests that Charlotte Turner Smith's mode of discourse in her use of notes and their relation to the text proper are never fixed in her contemplative blank-verse long poem, Beachy Head (1807). Even though the display of learning in the paratext partly supports the woman writer's claim to authority, this paper argues that Smith's endnotes also indicate her way of challenging the double bind for women writers, summoning masculine authority on the margins of her book while simultaneously interrogating essentialist thinking and instructions about one's identity in a culture and on the printed page. The poem shows how the fringes of the book can be effectively transformed from a masculine site of authority to an increasingly feminized site of interchange as Smith writes with an awareness of patriarchal, imperial abuses of power in that area of the book. There is a persistent transgression of cultural/textual boundaries occurring in Beachy Head, which explores the very scene and languages of imperial encounter. Accordingly, if Wordsworth's theory of composition suggests a subjective and abstract poetic experience-an experience without mediation-in which its medium's purpose seems to be to disappear from the reader's consciousness, an examination of the alternative discourse of self-exposure in Smith's poem reveals the essentially fluid nature of media-consciousness in the Romantic era, which remains little acknowledged in received accounts of Romantic literary culture.

This survey study was attempted for two purposes : 1) to grasp Korea National Open University(KNOU) students' changing aspects for their education need through comparison analyses with 1996 data ; 2) to establish foundation of the systematic network formation by investgating students' opinion about network framework. Among randomly assigned 4,500 students, 1,505 KNOU nursing students who allowed to participate in the study completed the questionnaires. The data were collected by mail. For the comparison 1996 data were also used. The data were analyzed using descriptive statistics, chi-square test, and t-test. Results of this study were as follows 1. The admission purposes of the KNOU nursing students were 'in order to get a bachelor's degree (70.7%)', 'to do studying and working simultaneously(43.0%)', or 'to be admitted for the graduate school (41%)' etc. Comparing the admission purposes by age, the investigator found 4 items which are 'small amount of tuition', 'graduate school admission', 'aspiration for the university', 'promotion or commencement of work' showed statistically significant differences. These 4 items were also found to show significant differences by marital status. 2. In relation to the learning media, the study showed most students(74%) got effective informations from the school newspaper(36.5%) or peer group(37.7%). The result showed that few students (0.7%) used the computer for communication. The research indicated that KNOU nursing students have tendency to rely on printed materials more than on broadcasting media. This is almost the same result as that of 1996. 3. The results revealed that 12.4% of the respondents had ever experienced unregistration or temporary withdrawal. The most common reason for the unregistration was 'due to family affairs or their job (71.3%)'. There were no change for this aspects with 1996. 4. As for the professors-students network formation. The result revealed that 38.5% students among respondents had heard of the network formation. 78.7% of respondents, however, positively responed that they would willingly participate in the networking if it is made. Especially the students showed much interest in 'the improvement for the understanding of study' and 'strengthening of the relations between professors and students'.

We successfully fabricated 4.7-inch organic thin film transistors array with $640{\times}480$ pixels on flexible substrate. All the processes were done by photolithography, spin coating and ink-jet printing. The OTFT-Electrophoretic (EP) pixel structure, based on a top gate OTFT, was fabricated. The mobility, ON/OFF ratio, subthreshold swing and threshold voltage of OTFT on flexible substrate are: 0.01 ^2/V-s, 1.3 V/dec, 10E5 and -3.5 V. After laminated the EP media on OTFT array, a panel of 4.7-inch $640{\times}480$ OTFT-EPD was fabricated. All of process temperature in OTFT-EPD is lower than $150^{\circ}C$. The pixel size in our panel is $150{\mu}m{\times}150{\mu}m$, and the aperture ratio is 50 %. The OTFT channel length and width is 20 um and 200um, respectively. We also used OTFT to drive EP media successfully. The operation voltages that are used on the gate bias are -30 V during the row data selection and the gate bias are 0 V during the row data hold time. The data voltages that are used on the source bias are -20 V, 0 V, and 20 V during display media operation.

High-quality and low-price digital printing devices are nowadays abused to print or forge official documents and bills. Identifying color laser printers will be a step for media forensics. This paper presents a new method to identify color laser printers with printed color images. Since different printer companies use different manufactural systems, printed documents from different printers have little difference in visual. Analyzing this artifact, we can identify the color laser printers. First, high-frequency components of images are extracted from original images with discrete wavelet transform. After calculating the gray-level co-occurrence matrix of the components, we extract some statistical features. Then, these features are applied to train and classify the support vector machine for identifying the color laser printer. In the experiment, total 2,597 images of 7 printers (HP, Canon, Xerox DCC400, Xerox DCC450, Xerox DCC5560, Xerox DCC6540, Konica), are tested to classify the color laser printer. The results prove that the presented identification method performs well with 96.9% accuracy.

Conformal coating is a technology that protects PCB(Printed Circuit Board) and minimizes PCB failures. Since the defects in the coating are linked to failure of the PCB, the coating surface is examined for air bubbles to satisfy the successful conditions of the conformal coating. In this paper, we propose an algorithm for detecting problematic bubbles in high-risk groups by applying image signal processing. The algorithm consists of finding candidates for problematic bubbles and verifying candidates. Bubbles do not appear in visible light images, but can be visually distinguished from UV(Ultra Violet) light sources. In particular the center of the problematic bubble is dark in brightness and the border is high in brightness. In the paper, these brightness characteristics are called valley and mountain features, and the areas where both characteristics appear at the same time are candidates for problematic bubbles. However, it is necessary to verify candidates because there may be candidates who are not bubbles. In the candidate verification phase, we used convolutional neural network models, and ResNet performed best compared to other models. The algorithms presented in this paper showed the performance of precision 0.805, recall 0.763, and f1-score 0.767, and these results show sufficient potential for bubble test automation.

Typography is the combination of language of formative art. It is indeed the core means of human communication through understanding of language and formative values. Studies began on introduction of various techniques to overcome the phenomenon of the 'reaction of language', which appears as an impediment in delivery and sharing of information as the most fundamental roles. Successively, mobile printing types more readable and effective in delivering of meanings have been developed, thus widely distributed for general use. However, although such printing types might be easily used in image and digital media, such as in computer monitors, screens and mobile phone LCDs, etc., it is in fact difficult to use these printing types in printed surfaces, the traditional medium of information delivery, or in sign systems frequently encountered in our surrounding environment. As a solution for this, it is intended to create an effect of communication closer to dynamic typography expression by approaching visual message delivery system from the essence and substance of the color application, which corresponds to the visual spatial expression effect, the core element of expression in dynamic typography to possess significantly more powerful effect in terms of both message delivery capacity and readability than the conventional means of static typography.

The purpose of this study was to identity the relationship of clothing involvement, consumer characteristics, and clothing buying behavior of college female students in China. A questionnaire was developed to measure clothing involvement, materialism, conspicuous consumption, reference group influence, clothing purchasing modes, fashion information sources. The questionnaire was administered to 390 college female students in Dandong of china. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were as follows: 1. Subjects were divided into low clothing involved and high clothing involved groups according to the level of clothing involvement. 2. Three dimensions of materialism were derived by factor analysis such as Happiness-pursuing, Life-centered, and Sucess-symbolic. And three dimensions of conspicuous consumption and reference group influence were derived by factor analysis such as luxury oriented, Status symbolic, Brand-name oriented, and Comparative, Informational, Normative exactly. Clothing purchasing motives and fashion information sources were factor analysed as Social and Individual mole, and Printed & Electric-wave media, Marketer managed, Personal exactly. 3. There were significant differences between high involved and low involved consumers in consumer characteristics and clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about materialism especially in Happiness-pursuing about conspicuous consumption in status symbolic and about influence of reference group in comparative. The high involved consumers put more importance than low involved consumer individual motive as clothing purchasing motive, and marketer managed in clothing fashion information. The high invoked consumers showed more importance than low invoked consumers about evaluating attributes of product, and about store patronage criterion.

This study considered the transition of changes in social status of the film through the discourse analysis of printed media, having been published since 6th revised film policy in 1987. For the purpose, Pierre Bourdieu's cultural sociology, or 'Field theory approach' was engaged as a theoretical background. On the basis of that theory, changes in social status was divided into expert and popular field. From 1988 to 2007, doctor's and master's theses on filmologie and the representative academic journal, "Film Studies" were examined with regard to area of expertise, and movie-related books with regard to popular one. This study demonstrated that the symbolic capital had inhered in the cinematic field along with specialization and diversification of analytic aspects, and the relation between the academic approach and political consideration had performed an important role in intellectualization of film.
