This study conducts a questionnaire with undergraduate students in the Dept. of Architecture who will lead the architectural field in future, examines environment and perception of CAD in their home and universities and aims at supplying the data required for setting CAD educational index and building its use environment, and it could obtain the following results. Individual CAD environment of undergraduate students in the Dept. of Architecture reach a considerable level in hardware part, but they don't have the same level in software part as the hardware and use illegal copy programs. It is shown that they spend their time in using CAD for five to eight hours a week and its main purposes are to perform a project related to architectural design or make report requiring drawing. Major places using CAD are CAD room in university or public PC room equipped with CAD compared to their own houses and most of them have a negative recognition of the convenience of its use. Their satisfaction with CAD use is considerably high and when they submitted their assignments of architectural design project by means of CAD, they had a positive evaluation from their professors and they have such hopes that 'Korean Support Strengthening', 'lowering price through version supply for students' and 'diversification of design symbol' in CAD S/W, and especially, most of respondents have an intention to purchase the original goods when version only for students will be marketed in future. Accordingly, for a qualitative improvement of CAD environment for undergraduate students in the Dept. of Architecture, universities must be equipped with the various types of CAD S/W and Applications and students' opportunity to access them should be increased. In addition, a method which can enhance using convenience of CAD room and PC room is required and CAD related S/W developers must market the version for students which consider the reality of undergraduates in Korea properly with an appropriate price level in order to settle a sound S/W culture.

Design in the 21st Century requires showing extraordinary and revolutionary possibilities by merging multiple cultures or different art forms. 21C fashion also increases its's complexity through the blending in of other design field's styles and forms. In other words, 21C's fashion design involves not only clothing, but combines techniques, aspects and functions fulled from various design categories. As a result, Current fashion design becomes more unique, and shows various styles. From this point of view, this study focuses on creating and suggesting unique textile designs through the understanding of design processes of textiles, which are inspired by high tech architectural structures. The fundamental shape of the architectural structures were simplified into thick lines and geometric shapes. these design elements were then transferred into textile designs. As a result, unique textile looks were created, and were applied to the apparel designs by CAD to see 3d simulations. Exchanging or merging ideas of different design categories leads innovative and fresh looks. 21C is rapidly changing, and designers need to continually introduce new looks every season. Incorporating 21st Century consumption patterns, designers must understand the process of creating original designs through various methods. The innovative fabric designs for this study involved a creative process of drawing from a step by step breakdown of two separate design fields, which were then merged into one finished design. The data and research from this study can be used as a reference tool for any further applicable fashion and textile designs in the future.

It may be replacement proofs with understanding and explaining geometrical properties that was a remarkable change in school geometry of 2009 revised national curriculum for mathematics. That comes from the difficulties which students have experienced in learning proofs. This study focuses on one of those difficulties which are caused by the forms of proofs: using letters for designating some sides or angles in writing proofs and understanding some long sentences of proofs. To overcome it, this study aims to investigate the applicability of Byrne's method which uses coloured diagrams instead of letters. For this purpose, the proofs of three geometrical properties were taught to middle school students by Byrne's visual method using the original source, dynamic representations, and the teacher's manual drawing, respectively. Consequently, the applicability of Byrne's method was discussed based on its strengths and its weaknesses by analysing the results of students' worksheets and interviews and their teacher's interview. This analysis shows that Byrne's method may be helpful for students' understanding of given geometrical proofs rather than writing proofs.

In shipbuilding and marine industry, engineering and design software solutions have upgraded from the original 2D schematic data based CAD system to a modern 3D drawing-based system. Due to the fact that the massive amount of data usage in real time and data volumes of various engineering models including graphic data have increased, several problems such as lack of server resources and improper handling of 3D drawings have been raised. Besides, increasing the number of session connections per server can cause deterioration of server performance. Recently, increasing the yard's sophisticated design capabilities highlighted the need to develop engineering and design system which would not only overcome the network performance issues, but would provide efficient collaborative design environment. This paper presents an overview of the framework for collaborative engineering design system based on the virtual application (Citrix XenApp 6.5)and acceleration hardware technology of 3D graphics (NVIDIA GRID K2 solution).

For given 3D geographic data which is usually of DEM(Data Elevation Model) format, we have to represent and manipulate the data in various ways. For example, we have to draw a part of them in drawing canvas. To do this we give users a way of selecting area they want to visualize. And we have to give a base tool for users to select the local area which can be chosen for some geographic operation. In this paper, we propose a 3D data processing method for representation and manipulation. The method utilizes the major properties of DEM and TIN(Triangular Irregular Network), respectively. Furthermore, by approximating DEM with a TIN of an appropriate resolution, we can support a fast and realistic surface modeling. We implement the structure with the following 4 level stages. The first is an optimal resolution of DEM which represent all of wide range of geographic data. The second is the full resolution DEM which is a subarea of original data generated by user's selection in our implemeatation. The third is the TIN approximation of this data with a proper resolution determined by the relative position with the camera. And the last step is multi-resolution TIN data whose resolution is dynamically decided by considering which direction user take notice currently. Specialty, the TIN of the last step is designed for realtime camera navigation. By using the structure we implemented realtime surface clipping, efficient approximation of height field and the locally detailed surface LOD(Level of Detail). We used the initial 10-meter sampling DEM data of Seoul, KOREA and implement the structure to the 3D Virtual GIS based on the Internet.

The objective of this research is to develop a method of improving MEP facility management based on 3D reverse engineering. Recently, 3D image scanning-based reverse engineering has been implemented in the fields of architecture, construction and (manufacturing). In the case where there are many objects and the MEP system is complicated, 3D reverse engineering is applied in semiconductor factories, because facility maintenance works cause the 2D drawing to be different from the original one. The 3D point cloud data obtained from 3D image scanning contains accurate data and can increase the efficiency of complicated MEP facility maintenance works. For this purpose, the present research studied the technology trends and analyzed the process of 3D reverse engineering. Based on the results, a method of improving MEP facility management is established and its effects described.

Comics are a genre that convey meaning through compositional arrangements of dialogue and images as well as through the flow of panels across a page. Communicating that meaning to readers through a combination of language and visual lexicons is the essential process of drawing comics, a process that in itself is significant. The semiotics of comics is a field of scholarship grounded in the broader discipline of semiotic theory in which all the components of comics, both visual and verbal, are the subject of study and research. By adopting a semiotic approach we are able to objectively analyze and understand the symbolic, social and ideological meanings embedded in the signs and sign processes expressed in comics. The fundamental pedagogical mission of teaching comics is to cultivate human nature through the study of theory as well as through the production and completion of original works that explore new modes of expression. To go further, interpreting those embedded meanings in the context of comics fosters effective and creative skills of expression that go beyond a mere fascination for the genre itself. In short, because the semiotic approach to understanding visual communication is the essence teaching comics, we can expect that the act of reading and creating comics plays a significant role in understanding visual communication.

One hundred and thirty one health articles (as 'original articles') reported in medical journals published in Korea during the period from Jan. to Dec. 1971. were selected as the study materials for tile purpose of resumption and criticism. Of a total of 131 articles, thirty-nine were not required the statistical application for the data processing and drawing their conclusions and ninty-two, 70.2%, were needed to apply. The 92 articles were divided into three groups by the types of study: 54 for experimental study, 30 for clinical case analytic study and 8 for field study. Each report was resumed and criticised under the statistical aspects in terms of data processing and the validity of the conclusions. The results of resumption of the 92 articles needed statistical application are summarized as follow; 1. Of the 54 articles of experimental studies resumed, thirty-one articles, 57.4%, were considered acceptable. Among the 38 articles classified as clnical case analytic and field studies, only 28.9 per cent were considered acceptable. In total 45.7 per cent or less than half were considered acceptable. 2. Types of errors encountered are as shown in Table 3. 3. The most frequently encountered error was that the conclusions were drawn without having made any statistical test. This type of error was found in 14 out of 35 errors presented in experimental studies, 11 of 35 in clinical case analytic studies and 5 of 9 in field studies and 30 out of 97, 38.2%, in total.

This study analyzes the characteristics of broadcasting law and telecommunication law and suggested the key legitimate of regulation where convergence law would go for in the convergence circumstances by drawing the common and differential characteristics of two laws. Moreover, in the value of inherent pursuit of broadcasting law and telecommunication law, this paper examined whether these values continued to be reflected in the convergence law, and indicated the direction how these values should adopt in the convergence law. The result of this study shows that strong entry regulation has applied to both broadcasting and telecommunications industry. Also, both industries have been required to be universal service to realize the value. Meanwhile, the pursuit of original value of broadcasting law and telecommunication law can be summarized as secure of access and diversity, respectively. In the convergence law, it is necessary to compensate and modify the meaning of access and diversity based on traditional regulation.

Modern society has been transformed into a digital emotional society that could gradually be seen, felt, and enjoyed by the diversification of personal consumption desires due to digital development. Accordingly, in fashion, an original fashion sense that arose out of classical and conventional thinking has become important and there is an increasing interest in patchwork quilts. The purpose of this study lies in contributing to the development and utilization of creative and emotional fashion design by expanding the mental changes that have emerged in modern society to creative areas after analyzing the classification and expression characteristics of the type cases of patchwork quilt techniques expressed in modern fashion. In addition, it is meaningful to examine how the expressive characteristics of patchwork quilts are expressed in the digital emotion era. This study paralleled literature research and empirical case studies. In the scope and method of research, the theatrical research was centered on literature data. For visual data, website photos were collected, limited to women's clothing among the collections from Fall & Winter 2014 to Spring & Summer 2017. After drawing the expression types of patchwork quilts extracted from the previous research based on the design formative factors, the fashion-related expert group analyzed the expressive characteristics of 501 photographs in which the patchwork quilt of the designer clothing collection were reflected. As a result of analysis, the expressive types appeared in the order of diversification of techniques and materials, extended dual images, new formative composition, and reconstruction of traditional patchwork. In this study, the expressive characteristics of patchwork quilts expressed in contemporary fashion are analyzed and drawn as variability, compromise, convergence, and playfulness. Through this, it is hoped that this study can be used variously in the development of fashion design by expanding the interpretation of costume culture.
