The lithographic process depends on a satisfactory ink-in-water emulsion being formed during printing and the speed of wet presses makes the choice of fountain solution vitally important as the ink and fount must react quickly to form a stable emulsion. Ink and water come into contact with each other on the rolls of the press and are forced together in the roll nips. The water is not soluble in the ink since it is slightly fat. Instead, an emulsion is formed, a heterogeneous mass consisting of small water drops mixed into the ink, if the water feed is too great. This emulsification can affect the properties of an off-set ink and negatively affect the printability. So we investigated the effects of the emulsification of phenol free heat-set ink and existing heat-set ink on printed quality, such as amount of ink transfer, printed density, print-through and uniformity. We used Duke emulsification tester for the emulsification of inks, and used IGT printability tester for printed quality. The printed quality were measured by densitometer and were evaluated by the image analysis system. Compared to conventional printing ink, phenol-free ink showed better results of the printability at the emulsification.

This paper presents an vulnerable road user (VRU) classification and tracking algorithm using vision and LiDAR sensor fusion method for urban autonomous driving. The classification and tracking for vulnerable road users such as pedestrian, bicycle, and motorcycle are essential for autonomous driving in complex urban environments. In this paper, a real-time object image detection algorithm called Yolo and object tracking algorithm from LiDAR point cloud are fused in the high level. The proposed algorithm consists of four parts. First, the object bounding boxes on the pixel coordinate, which is obtained from YOLO, are transformed into the local coordinate of subject vehicle using the homography matrix. Second, a LiDAR point cloud is clustered based on Euclidean distance and the clusters are associated using GNN. In addition, the states of clusters including position, heading angle, velocity and acceleration information are estimated using geometric model free approach (GMFA) in real-time. Finally, the each LiDAR track is matched with a vision track using angle information of transformed vision track and assigned a classification id. The proposed fusion algorithm is evaluated via real vehicle test in the urban environment.

To characterize the coating structure, diverse methods such as mercury intrusion, nitrogen adsorption and oil absorption methods have been developed and widely employed. These indirect techniques, however, have some limitation to explain the actual coating structure. Recently microscopic observation methods have been tried for analyzing structural characteristics of coating layers. Preparation of the undamaged cross section of a coating layer is essential for obtaining high quality image for analysis. In this study, distortion-free cross-section of the coating layer was prepared using a grinding and polishing technique. The coated paper was embedded in epoxy resin and cured. After curing the resin block it was ground with abrasive papers and then polished with diamond particle suspension and nylon cloth. Polished coating layer was sufficient enough to obtain undamaged cross sectional images with scanning electron microscope under backscattered electron image mode. In addition, the SEM images allowed distinction of the coating layer components. Also S/B latex film formed between pigment particles was visualized by osmium tetroxide staining. Pore size distribution and pore orientation were evaluated by image analysis from SEM cross-sectional images.

The purpose of this study is to show inherent and differentiated beauty by designing costume knitwear using Dancho patterns representing peculiar beauty, thus expressing free and convenient knitwear in the modern sense for women with the image of reasonableness and elegance, proposing knit design using high-class materials for satisfying the demand for the highest. With regard to expression technique of works, I selected computer Jacquard method to indicate effective comparison effect of expression material and made expression with $12{\sim}14$ gauge as base by using computer knitting machine. Through above-mentioned research process and design using Knit CAD system, I obtained following conclusion. First, it is possible to express variously and widely traditional patterns by making the most of the beauty of the orient and by recomposing the patterns of plant patterns representing "feminine image". Second, it is possible to widely represent the sense you can feel from knit by expressing variously diversity of knit structure and Jacquard knitting structure and gauge. Finally, it is possible to express designs more freely and imaginably by using computer Knit CAD system instead of actual knitting of various knit expression technique and materials application.

The new principle to measure a sizing degree by a contact angle was developed using an automatic determination of the 3-end point coordinates of the water droplet on a sheet, which could diminish the operator's bias during measurement. A constant amount of water was first placed on a sample sheet by a water dispenser, and then an image of the liquid droplet was captured by a digital camera and then transmitted to a computer. The program measuring for contact angle extracted a liquid contour by Gaussian function combined with a 8-direction chain code. The Euclidean equation was applied to the binary image of the liquid contour in order to measure the diameter of the contour. Finally, the contact angle of the liquid was calculated by using the diameter and the top coordinates. In addition, a surface free energy of the sample sheet and an elapsed time taken up to the complete absorption into the sheet were simultaneously measured with the contact angle.

In the era of 2.0 web, blog has become the media that men can express themselves with fashion more actively and independently, as paying much attention to their personal appearance and cultivating an upscale lifestyle. They often create their fashion images in the virtual space where enables a free and creative operations of self-expression. The study aims to identify the types of men's ego-images represented on the personal fashion blogs based on the framework of analysis from the previous research (Suh, 2014), to build the base data for analyzing men's fashion style in $21^{st}$21st century that reflects changes in men's sexual images, and to verify the framework as comparing with the previous case study about the women blogs (Suh, 2014). The case studies conducted 5 men's personal blogs such as bryanboy, iamgala, little fashionisto, katelovesme, and stylentonic. The study results almost same types of women's ego-images as following. The imaginary ego-image is classified as narcissism, regression, identification, and virtuality, the social ego-image as symbolism of roles and others'desire, the real ego as primary instinct, practical reality, object a, jouissance and sexual perversion. The personal style of men shown on the fashion blogs appears as a significant factor to analyze male customers in the growing men's beauty and fashion market.

In contemporary advertising market, one of main trends is to speak surrealistic visual language which provides 'enjoyable spectacles'. Specially, in the beginning of 21st century, there discovered more and more exhibitions and discourses about surrealism reinterpreted from the viewpoint of postmodernism. Surrealism as a creative style of expression based upon free association, has been a great inspiration for fashion ads for commercial communication as well as fashion design since its origin. However, there has been ignored the idea of analyzing surrealistic image expressed in fashion ads in spite of their flood. Accordingly, the purpose of this study is to grasp its cultural meaning through analyzing aesthetic characteristics of surrealistic image expressed in fashion ads. It will provide a better understanding of surrealistic image in fashion ads reflecting popular taste and preference directly as popular visual culture, focusing on post modern context. A case study of surrealistic fashion ads limits to TV or print commercials and digital ads as image ads stimulating visual expressions. The Results can be summarized as follows. Surrealism is an avant garde style which deconstructs the established meaning system as well as the existing formalistic order and then put them together in the frame of 'dream' and 'unconsciousness'. Defamiliarization questioning the whole edifice of representation can be adapted to. By means of paradox and metaphor, unfamiliar new visual world can be represented. The plastic characteristics of surrealistic image in fashion ads are founded as surrealistic styling of time and space, distortion of object by methods of automatism, depaysement, parody and trompe-l'oeil which bring about the deconstruction of gestalt. Aesthetic values of surrealistic fashion ads appear as dualistic representation, allegoric symbolism, fantastic romanticism. Ultimately they lead to marvelous. mysterious, humorous visual effects. Foster reinterpreted these effects of surrealism from Freud's 'Uncanny Concept'. 'Uncanny' means the phenomenon recurring to familiar being defamiliarized by repression. Surrealistic fashion ads strengthen this shocking effect more and more dramatically in company with our post modern needs for fantastic adventure and thrilling spectacle. It can be thought that surrealistic fashion ads reflects uncanny as an alternative which can relieve us of our stress and anxiety and which realize our potential desire in contemporary post industrial stage.
