This research, mainly focused on the development of the iPhone exclusive app 'Sketch Plus', is on the production of pens within the smart media. Our goal is to develop and reproduce pens with surreal rendering as a base and during that process, describe the fusing process of design perspectives and algorithms. This research comprehends the concept of surreal rendering, which is a technique that mimics traditional art forms, and suggests 15 pen techniques and ways to display them by analyzing previous research on smart media. We have described the process of using hatching patterns and resused to solve lag problems that occur during the reproduction of pen techniques due to the limitations of smart devices and organized the conversion process of pen patterns into 4 steps: rough sketch, contrast, applying and mimicking patterns, and applying color. We hope that this research on the reproduction of analog pen techniques can be used as an example for production on fused surreal rendering.

ISO 10303-112 is an integrated application resource of ISO 10303, commonly known as STEP, and specifies the procedural_sketch schema. The ISO 10303-112 provides general resources for the representation of modeling commands for the exchange of procedurally represented 2D CAD models. Procedural models have the advantage of being easy to edit, simply by changing values of parameters of their constructional operations. Such models are said to embody design intent, in the sense that modifications to them conform to the method of creation used by their original creator, and they also comply with any constraints implied by the particular constructional operations used. This paper introduces the development and standardization process of the ISO 10303-112, and describes the concept of procedural 2D CAD modeling, the way to represent the procedural 2D CAD models in STEP and the harmonization with other STEP resources.

The Cosmic Microwave Background (CMB) contains a wealth of information about the perturbations in the early universe. Its bispectrum, the Fourier counterpart of three-point correlation functions, is a direct probe of primordial non-Gaussianity predicted by many physically well motivated inflation models. Motivated by the substantial improvement in sensitivity expected from future CMB surveys, we developed a novel bispectrum estimator capable of handling such high-resolution data. Our code, named CMB-BEst, utilises a set of separable basis functions to constrain a wide variety of models simultaneously. Flexibility in the choice of basis enables targeted analysis on highly oscillatory inflation models, which are previously unconstrained due to the numerical and computational challenges involved. We present the results of our thorough validation tests, both internal and against conventional approaches. We provide a proof-of-concept example with Planck satellite data and sketch out the road ahead.

With the rapid development of nowadays technologies, the environment of product development is experiencing structural changes than ever. Manufacturers are put under never-experienced pressures to launch their products in the market both faster and less expensively than their competitors while continuously improving product quality These pressures have given birth to so-called, Concurrent Engineering which is a systematic approach to the integrated, concurrent design of products and their related processes, including manufacture and support. Most manufactiring companies now recognize the importance of concurrent engineering and put heavy emphasis on the research and impementation of concurrent engineering. However, with this fundamental change in the process of product development, designers rarely pay attention to this newly demanding process. Designers still stay in the middle of process, satisfying their roles in dealing with aesthetic points of product. Designers badly need to incorporate the concept of concurrent engineering to design to design process and to adapt to this new environment. With these backgrounds, the study sets the objective to understand the nature of concurrent engineering and explore the possibility of it's application to industrial design. Particularly this study focuses on how the concept of concurrent engineering can be applied from the stage of form development to prototyping. At first, background, objectives, and scope of the study are discussed as an introductory part. It is followed by reviewing theories of concurrent engineering such as definition, history, technologies, examples, state of art and so on. Subsequently industrial design is viewed in terms of concurrent engineering and problems in industrial design are identified. Base on the findinss of precedent part of study, new process of industrial design incorporating concurrent engineering is developed. For the demonstration of new process, a case study of design of palm-top printer is introduced. Case study shows how the sketch, and forms can be transformed into prototyping with the simultaneous cooperation with engineering and other related specialists. Finally the study in summarized and future studies are prospected.

Traditional rendering of cartoon character cannot revive the feeling of concept drawings properly. In this paper, we propose capture technology to get toon shading model from the concept drawings and with this technique, we provide a new novel system to render 3D cartoon character. Benefits of this system is to cartoonize the 3D character according to saliency to emphasize the form of 3D character and further support the sketch-based user interface for artists to edit shading by post-production. For this, we generate texture automatically by RGB color sorting algorithm to analyze color distribution and rates of selected region. In the cartoon rendering process, we use saliency as a measure to determine visual importance of each area of 3d mesh and we provide a novel cartoon rendering algorithm based on the saliency of 3D mesh. For the fine adjustments of shading style, we propose a user interface that allow the artists to freely add and delete shading to a 3D model. Finally, this paper shows the usefulness of the proposed system through user evaluation.

This thesis is a study on Sook-Jae Lim(1899~1937) and Korean modern design. In modern Korea, design like most cultural advances came from western culture, that was introduced via Japan. So Korean design can be betterunderstood from observing Japanese modern design history. The research on Japanese modern design, however, is not being done actively. Sook-Jae Lim was the first Korean to graduate from the Department of Design at Tokyo Fine Arts School (currently the Tokyo National University of Fine Arts and Music). He died at a premature 38 years old, so very little of his works exist. That makes the study about him very difficult. From this perspective, the study aims to examine modern design concepts and styles accepted into Korea from Japan and position Lim as an early design pioneer in Korean design history, by using research of Korean and Japanese design fields in the modern era with focus on Lim and his works. Chapter II researches the process of how the concept of design was formed in modern Japan and how the "Art-Nouveau" style not only represents early modern design but also features Lim's works dominantly. Chapter III looks into the process of how the concept of design was formed and which design styles were introduced and applied in modern Korea. Chapter IV analyzes how Lim's viewpoint on design and his works were developed with observations about the tendency of the Japanese design field and curriculums of the Tokyo Fine Arts School during the period of his college days.

The designers pursue the thoughtful and wide thinking through the accumulation of knowledge and cultivation of insights for making use of high-level design philosophy and language. The purpose of this study is to investigate characteristics of concept figuration types based on designer's 'memory' in landscape design. The results of this study are as follows. First, the design idea starts to be based on the language and image memory of the designer. The figuration types are composed of the verbal and visual view which are representative communication means. Second, the verbal concept figuration of landscape design consists of two types. The symbolic language of the title as a design theme can be a 'phrase', and it should have a hierarchial balance between the master and the sub. 'Descriptive shape of conceptual scenario' is a text that expresses the concept narratively in order that the reader virtually experiences designed landscapes. Third, visual concept figuration of landscape design is divided into three types. 'Simple visualization of a diagram' is easily embodied through a simple graphic using symbols, comments, images and key words. 'Concept sketch and shape of core idea' is useful to grasp the core of the idea such as physical element, form attribute of space and spatial relation at the initial phase of the concept. 'A collage and montage that create a new shape with a combination of images' are a collection of materials and images that provide a new perspective. These are tools to depict them in a compressed way after recording landscapes phenomenon.

Since the significance of the living room has been stressed as the space for family gathering, the weight of an ornamental console among the living room furniture is being increased. A console is an excellent small-sized furniture to highlight the spatial characteristics by being placed in front of the plane wall, which is left as an empty space or between doors. Therefore, this study aims to defined a console and to understand the issues raised on it by analyzing the domestic and international data that are addressed until today. Meanwhile, various consoles in the market today were analyzed through catalogues, data derived from internet, and literature sources on furniture to conduct the processes of idea sketch, rendering, design confirmation, design draft, and computer rendering (3D). As for the design concept of a console, modern design equipped with practicability and ornamental is adopted in the form of a combined console table and flower vase. In terms of economic feasibility and versatility, the design is developed to allow the console use by removing the glass pipe depending on needs and in case of using a flower vase, small flower can be decorated using a glass pipe for the ornamental effect.

Information gathered through experience transforms into knowledge and such knowledge becomes a foundation for intuitive decisions. Based on such background, the following study investigates intuitive decision making on basic elements needed for design concepts and visual conceptualizations. The study consist two phases. first, 12 structural elements of a digital camera and relation between each elements were arranged intuitively on a board. Next, sketches were generated with relationship of structural elements in mind. As a result of the study, concept with intuitive decisions effect structural thinking, various developments, specific operation methods , and sketch expressions. However, study also revealed that the freedom of human emotions don't accord with the qualification map.
