본 논문에서는 TCP/IP프로토콜을 사용하는 LAN환경에서 PC들을 사용한 PC클러스터에 관해 연구하였다. LAN환경의 PC들은 안정된 사용환경을 확보할 수 있고, 특정한 사용 시간에 따라 작업을 배치할 수 있는 특징을 갖는다. 또한 별도의 전용의 클러스터를 설치하기 위한 하드웨어가 필요로 하지 않는 장점도 갖는다. 특히 PC실험 실습실의 PC들은 주로 주간 시간대(오전9시~오후6시)에만 실험실습 수업에 사용이 되고, 야간 시간대(오후6시~익일 오전9시)에는 사용되지 않는 유휴 시간을 갖는다. 이러한 사용되지 않는 유휴 시간대의 PC들을 CPU지향적인 복잡한 작업들을 연산하기 위해 사용할 수 있으며, 별도의 클러스터 시스템을 구성하기 위한 하드웨어(클러스터를 위한 컴퓨터들, 스위치장비, 케이블링 등)를 구입할 필요가 없기 때문에 저가격의 고성능을 요구하는 PC클러스터를 쉽게 구성할 수 있다. 공동실험실습실의 PC들마다 유휴기간을 Time table에 예약하고 이에 따라 작업을 배치하고 연산결과를 수집한다. 장기간의 연산작업이 필요로 하는 대규모 연산에 사용함으로써 상당한 경제적 효과를 얻을 수 있다. 또한 동일 실습실의 PC들은 대개 동일한 성능의 동일한 하드웨어와 운영체제를 사용하는 PC들로 구성되기 때문에 Homogeneous node로 구성된 PC 클러스터를 구축하기가 용이하다.

포괄적인 개념에서, 게임에서 인공지능이란 PC(Player Character, 사용자에 의해서 조정되는 게임 오브젝트)를 제외한 모든 것들을 제어하기 위해 사용되는 일련의 기술이라고 정의할 수 있다. 예를 들면, PC를 둘러싸고 있는 환경, PC를 대적하거나 경쟁관계에 있는 NPC(Non-Player Character), PC에 조언을 해주는 조언자 NPC 등을 제어하고 사용자가 느끼기에 지능적이면서 실제적인 것으로 보이도록 하여 게임의 흥미를 더하기 위한 기술들이다. (중략)

The deterioration of PC box girder may cause serious effect on the durability of PC structure compared to that of RC structures. In the durability assessment of PC box girder bridges, a quantitive model on crack width is considered as a measure of durability. This study suggests a durability limit state model for PC box girder bridges. This durability limit state model in formulated based on the conventional models on the cracks in concrete. And the allowable crack width is taken as an assumed value established by the design specification or provided by the maintenance authority of the structure.

본 논문은 일반적으로 쓰이고 있는 PC 케이스 내부에서 발생하고 있는 소음 요소를 분석한 후 내부적 시스템 변화가 아닌 외형적인 변화를 통하여 PC 케이스 내부에서 발생하는 소음을 저감하는 효율성을 제공하고 더 나아가 친환경적인 디자인을 통한 업무 효율성을 높일 수 있기에 일반적 케이스 모델인 직육면체의 PC 케이스에서 팔면체의 PC 케이스를 제안하였고 그에 따른 실험적 결과를 토대로 새롭게 제안한 PC 케이스가 일반적 PC 케이스에 비해 높은 차음 효과가 있음을 제시하였다.

In the context of the number of Tablet PC users which increases rapidly, online shopping application has also been a corresponding rapid development. However, as a practical matter, the differences among the consumers' ability will affect the purchase of application for the realization of user needs. Therefore, shopping application in the GUI design to improve consumers use needs to be improved to meet the demands of different users. In view of this problem, this paper has carried on the related research on the GUI design of Tablet PC application, and fully considers the visualization image elements of information transmission, then analyzed the top five shopping application in Chinese market via three visual elements - icon, label and color. In addition, it conducted a questionnaire which based on the object of Tablet PC shopping application Chinese users. Consequently, what obtained is, based on the survey findings, the GUI design proposal which reasonable reflects the shopping application with functionality and designability. Through the research results of this paper, we can get the conclusion that the three kinds of visual GUI elements-icon, label and color- have the influence on the user's usability. In addition, this study can be expected as a reference in the shopping software GUI design.

The construction method using PC(Precast Concrete) has been widely used because the method can shorten the construction period and improve construction quality. In this paper, through the analysis of present design process for PC railway platform, design parameters on the geometry and properties were extracted and 3D information models for PC railway platform were constructed by the parametric modeling technique. Furthermore, the interface module was developed to link 3D models to the structural analysis/design sheet and database program using VBA(Visual Basic Application). This information model could be used in various areas including structural analysis and design, 2D drawing, quantity estimation and 4D simulation including clash detection.

This paper would suggest about data communicate using RF Transmitter-Receiver and about PC protection method authenticate using software of PC which Receiver is connected. Older PC protection system is demanded manual operation of the user but the suggesting method protect PC automatically with judge existing of the user who has Tag approaches the distance which gets near. And it is impossible about the forgery and it is safe about sniffing attack and spoofing.

This study is intended to propose a systematic and practical life cycle cost(LCC) model for the development of the reliability-based seismic safety and cost-effective performance criteria for design and upgrading of long-span PC bridges. The LCC models consist of five cost functions such as initial cost, repair/replacement cost, human losses, road user cost, and indirect losses of regional economy. The proposed model Is successfully expressed in temrs of Park-Ang damage indices and life cycle damage probability obtained from SMART-DRAIN-2DX which is an existing algorithm for nonlinear time history analysis. The proposed LCC model is successfully applied to a viaduct constructed by PSM, in Seoul. Based on the observations, the proposed systematic procedure for the formulation of LCC model may be useful for the development of the reliability-based seismic safety and cost-effective performance criteria for design and upgrading of long-span PC bridges.

Recently, the ubiquitous computing environment being able to connect all kinds of computing elements at anytime anywhere becomes widespread in human life. In this paper, we focus on a PC remote control system using cellular phones. Especially, we design and implement an mobile e-mail transmission system using PC remote control technique. By using our remote controller, cellular phone users can login into their own PC, and then send any file to others by e-mail attachment. To show the correct running of our system, real demonstration results are presented. We are sure that by opening our source code to the public our results can play an important role to encourage development of the various mobile remote control functionalities.
