A design pattern is a general solution to a commonly occurring problem. Design patterns have proven highly effective in representing, transferring, and applying the design knowledge in many engineering disciplines. However, these patterns have not addressed sensor network specifically. With a growth of sensors and sensor networks, and considering their profound applicability, there is a crucial need to articulate ones experience of application development or deployment of sensor nodes in the form of design patterns to avoid the future mistakes. This paper discusses the same issue and show applicability of design patterns in sensor networks.

In this study, computer program for the optimum design of agricultural aqueduct tunnel was developed. It was shown that even though the starting points and optimization method are different, the objective function and optimum design variables converge to a value within a close range respectively, and consequently the optimum design program developed in this study is reliable and robust. 3D-design drawing can be drawn using automation design computer program developed in this study

Object-oriented programming goes on increasing in many areas, as its advantages of flexibility and ease of maintenance have been recognized. As in usual programmings, the productivity and flexibility of CACSD package can be improved by adopting object-oriented programmin. This paper describes our efforts to implement an OO-CACSD(Object Oriented CACSD) package for control system design and simulation. Since the proposed OO-CACSD is based on the modularity, portability, reuseability, and matrix-oriented data structure, a control system can be not only modeled and simulated but also maintained easily.

This paper shows design of maximal-period sequences with prescribed constant auto-correlation values based on one-dimensional (1-D) maps with (mite bits. We construct such 1-D maps based on piecewise linear onto chaotic maps. Theoretical analyses and some design examples are given.

The main purpose of is paper is to review and develope design techniques with respect to geographic information system (GIS) using computer graphics. The geographic information system is a system designed to capture, store, manipulate, retrieve and display various data about geographic locations and spatial characteristics. In order to perform this research, a significant literature review was conducted and various design techniques of GIS based upon computer graphice were discussed.

본 논문은 보정 이미지에서 최 근접 좌표를 이용한 방사 왜곡 보정 하드웨어 구조를 제안한다. 기존 보간법과는 달리 보정 이미지에서 최근접한 좌표의 거리를 이용하기 때문에 이미지 전체 영역의 화질 향상과 함께 외각영역에서 발생하는 계단 현상을 해결할 수 있다. 그러나 양 선형 보간법을 적용한 기존 구조에서 추가되는 연산으로 인해 하드웨어 크기가 증가한다. 이를 해결하기 위해 룩 업 테이블 구조를 제안하고, 코르딕 알고리즘을 적용한다. Design compiler를 이용하여 합성한 결과 보간법의 모든 과정을 하드웨어로 구현한 구조는 기존 구조에 비해 처리량이 높고, 차량용 후방 카메라의 경우 룩 업 테이블과 하드웨어를 함께 사용한 구조는 모든 과정을 하드웨어로 구현한 구조보다 하드웨어 크기를 10% 줄일 수 있다.

This study aims to develop a mechanic embroidery bag design that reflects the symbolic image of Korean independence activists who sacrificed for the country so that today's Korea can exist. As a research method, the theoretical consideration and image collection of independence activists were conducted through a literature review and visits to the memorial halls of six independence activists. The bag design was developed using mechanic embroidery textile of 12 motifs manufactured in previous studies through the computer mechanic embroidery sewing machine, and the types were limited to totes, Boston, clutches, baskets, shoppers, hover bags, and hat boxes. The results of this study are as follows. First, it was found that the dense light and shade and delicate color expression of each motif design were the most important and achieved through the proper selection and utilization of embroidery yarn according to the mechanic embroidery expression technique for developing in-depth textile materials. Second, unlike in the past, when machine embroidery was difficult to handle, the spread of embroidery CAD and computer machine embroidery sewing machines made it easier for individuals to develop embroidery products. Third, this study once again emphasized the symbolism of Korean independence activists who sacrificed for the nation to exist at a time when it needs to be recognized due to the lack of fashion and diversity in cultural products containing historical and cultural meaning and values of the country. This study was able to develop computer machine embroidery textiles and various bag designs using various mechanic embroidery expression techniques that can highlight the symbolic image of each motif.

In 1970s, Computer Graphics of still and geometry changed computer Animation of image, and Computer Animation has diversely been used in movie, TV, fashion, sports, education, basic science, medical science, etc. by the development of LSI technology and the large size of computer in 1980s. Since Computer Animation was first used by movie of Futureworld in 1973, we easily experienced the essence of Computer Animation made of the Little Mermaid. Beauty and the Beast, the Lion King, Aladdin, etc. in Disney Animation and Terminator. Jurassic Park, the Mask, etc. in movie. And in other countries that have got the diversely special effect and knowhow in technology are effectively using the Computer Animation now. What situation we Korea are in now, if we compare the Computer Animation with that of other country using the progressive movie\ulcorner Although we first producted the movie title of Ticket, 10years ago, we have rarely been used it in movie, yet. Therefore, we know that it is very important for us to examine the historical and technical side for the purpose of overcoming the technological gap.

Currently with the continuous development of ceramic and cementation materials, CAD-CAM(Computer-aided design/Computer-aided manufacture) restorations are becoming increasingly popular in esthetic dentistry. Preparation design is influenced by the selected restorative material, the fabrication method, and the ability to bond the restoration. For long-lasting CAD/CAM inlay/onlay restoration, clinicians should understand the basic knowledge of CAD/CAM restoration's cavity design to obtain the fracture resistance and proper fitting margin. This article gives an overview of preparation guidelines for CAD/CAM inlay/onlay restorations.
