Web pages with complex layout and small font size do not display well on large screen display such as TV because it has limited capabilities: long distance view, passive user attitude, limited input device like a legacy remote controller. We have designed and implemented new semantic zoom browsing facilities to support effective navigation on Internet-connected digital television with limited capabilities. Our browser performs partitioning of an HTML document content into semantic blocks. Semantic blocks present summarized information with more readable style and modified layout for optimal reading and browsing. Individual blocks can be selected by the user and zoomed in more detail information by the user. The scrolling on large display device needs more user interaction. Our browser modifies the layout of an HTML document with removing horizontal scrolling and minimizing vertical scrolling. This method allows users to easily view the web page by converting into optimal reading style and layout and to easily seek the information just with zooming.

In this paper, we introduce a method of light focusing effect using prism structure to solve optical discontinuity of conventional external signage LED panels. The prims structures were patterned on a transparent polycarbonate substrate with MEMS and femto-second laser process. We have confirmed that the patterned prism structures on the substrate made artificial LED lights on empty space between the panels by light guide effect of the structure. The artificial light's lateral positions were controlled by thickness of polycarbonate substrate. This cost effective prim patterned transparent film can be utilized on digital signage LED panels to achieve good optical communication.

We could use a social networking service such as data communication, personalized service through smart devices as Tablet computers and smart phones. Because of these characteristics, suitable lectures are provided to mobile device. especially, in Korea Cyber University already had built a lot of infrastructures. But, many mobile devices are used in a small display environment. it could effect on reduce Students' efficiency from taking courses. Therefore, we need effectively in a small display content layout for overcome these problems. In this paper, proposed the platform for Improve learning effect in smartphone education. It studied based on golden section and golden spiral theory. and also, we developed layout for content development using vector method illustration program.

n this thesis CAM(content Addressable Memory) generator and graphic display tool for run-plot sequence in automatic generation of CAM are presented. We show that implementing the layout generation, graphic menu, mouse driver, and data structure by using the basic classes is clear and easy in modification than the conventional procedural language. For the implementation of generator which is independent of design rule or process, we use the parameterized cell so that basic cell can be changed according to user's inputs. and perform the layout by means of placement and routing using pitch mathching. Finally, the display of CIF which generated and constitution of graphic menu for total run-plot sequence are explained.

IT companies are increasingly taking interest in the automobile industry as a major industry of the future. Companies specializing in information technology, such as Google, Apple and Samsung, are actively taking part in the automobile industry and are conducting various research on connected cars. At this point in time, this study aims on understanding the concept of connected cars and the concept of mirror linking, which is one of the many methods in connecting cars. In this transitional period of connected cars, the purpose of this study is to present the method of mirror linking iPhones and to discover how this could be used in connected cars. By turning a normal car into a connected car, simply with a smartphone in hand, the ideas presented in this study will serve as an opportunity for many current automobile owners to experience the functions of connected cars of the future without shouldering additional expenses.

Recently, fan out wafer level packaging, which enables high integration, miniaturization, and low cost, is being rapidly applied in the semiconductor industry. In particular, FOWLP is attracting attention in the mobile and Internet of Things fields, and is recognized as a core technology that will lead to technological advancements such as 5G, self-driving cars, and artificial intelligence in the future. However, as chip density and package size within the package increase, FOWLP warpage is emerging as a major problem. These problems have a direct impact on the reliability and electrical performance of semiconductor products, and in particular, cause defects such as vacuum leakage in the manufacturing process or lack of focus in the photolithography process, so technical demands for solving them are increasing. In this paper, warpage simulation according to the thickness of FOWLP material was performed using finite element analysis. The thickness range was based on the history of similar packages, and as a factor causing warpage, the curing temperature of the materials undergoing the curing process was applied and the difference in deformation due to the difference in thermal expansion coefficient between materials was used. At this time, the stacking order was reflected to reproduce warpage behavior similar to reality. After performing finite element analysis, the influence of each variable on causing warpage was defined, and based on this, it was confirmed that warpage was controlled as intended through design modifications.

Presentation is the most important factor in the usability of a web site. A poor layout makes a bad influence on the searching ability of the user by reducing search speed and causing mistakes. Recently many web sites visualize 3D information and there is plenty of research on it. Such a layout improves the usability of web pages and information awareness both in quantity and quality. This paper proposes design guides on 3D information browsing and has experiments on searching speed of the users for 2D and 3D displays of the same data and were analyzed.

최근 IT 기업들이 자동차에 IT도입에 열을 올리고 있으며, 그 중에서도 미터 클러스터는 운전자의 편의성을 고려하여 많은 연구와 관심이 증대되고 있다. 자동차 계기판은 전자기기의 발전과 더불어 아날로그 계기판, 디지털 계기판, 이 둘을 함께 사용한 하이브리드 계기판, 그리고 보다 상세한 정보를 이미지와 함께 제공해 주는 스마트 하이브리드 계기판으로 발전하고 있다. 기존의 미터 클러스터는 단순히 차량의 제한된 정보를 표시하며, 운전자의 운전 상태에 따른 시인성이 부족하며, 차량의 상태, 그리고 운행지역의 주변 환경적 정보의 부족으로 인해 운전자의 안정성이 고려되지 못한 부분이 많아 운전자의 안전 운전에 도움이 되지 못하는 부분이 많다. 따라서 본 논문에서는 차량의 상태, 운행 환경정보 등의 통합 된 정보를 LCD 디스플레이 기반에서 운전자의 시인성과 안정성 우선으로 하는 레이아웃을 연구하고자 한다.
