이미 웹은 광고 매체의 성격으로서 자리를 굳힌지가 오래되었다. 인터넷은 모든 고객과 일대일 대응, 잠재고객의 세분화, 시공간의 한계극복, 멀티미디어의 이용가능이라는 장전을 지니고 있다. 1) 이와 같이 커뮤니케이션 수단으로서 웹은 기존매체의 특성을 모두 포함 할 뿐만이 아니라 소리와 움직임, 상호작용이라는 요소가 추가된 광고 매체로서, 다른 매체의 디자인보다 훨씬 유동적이고 개방적이어야 한다. 그럼에도 불구하고, 현재 대부분의 웹은 형식적이고 기능적인 형태만 갖춘 제작물들이 주종을 이루고 있다. 이는 폭발적인 수요차 더불어 웹디자인의 분야 역시 급속하게 발전되었기 때문에 아직 방법론적 측면이 뿌리 내리지 못한데서 비롯되었다. 따라서 이번 연구는 이러한 방법론적 측면의 한가지 대안으로서 인터페이스 디자인에 대한 접근방법을 제시하고자 한다. 2) 즉 'e광고컨셉트'에 따른 인터페이스 정.동디자인이다. 광고매체로서 웹은 다른 어느 매체보다 사용자의 감성적인 부분이 가장 큰 비중을 두고 있다. 따라서 사용자의 감성적인 부분을 통한 웹 인터페이스디자인의 '차별화' 및 '임팩트'는 매우 중요하다. 이를 위한 보다 구체적인 연구 접근을 위해 사용자의 감성적인 부분에서 추출한 'e광고 컨셉트'를 통해 웹의 다양한 조형요소 가운데 시각적으로 가장 먼저 눈에 띄는 요소인 움직임과 3) 그와 상반되는 정지와의 유기적 상관관계에 대한 결과로서 웹 인터페이스 디자인의 '차별화' 및 '임팩트'를 발견하고자 한다.

The traction drive have a high power transmission efficiency and small size, a light weight, a low noise. So it is expected that alternative drive part of engine. Because it is necessary stillness that essential condition of drive part used moving tool in a room, it has many-sided in field of application. This traction drive is better suitable than other speed reducer as drive part of electric wheelchair. Also it is sufficiently necessary capacity of existing advanced product as apply traction drive to electric wheelchair.

The responses of a 1:5 scale 3-story masonry-infilled RC frame which was designed only for gravity loads were simulated by using a nonlinear analysis program, DRAIN-2DX The objective of this study is to verify the correlation between the experimental and analytical responses of masonry-infilled RC frame. It is concluded from this comparison that the strength and stillness of the whole structure can be predicted with quite high reliability using compressive strut (compression link element, Type 09) while some local behavior cannot be described reasonably.

This part of specifies the method for determining the dynamic stiffness of resilient materials used under floating floors. Dynamic stillness is one of the parameters that determine the sound insulation of such floors in dwellings. This part applies to the determination of dynamic stiffness per unit area of resilient materials with smooth surfaces used in a continuous layer under floating floors in dwellings.

Magnesium alloys are very attractive materials for appling to the development of autemobile parts or electric goods where light weight and higher stiffness. Due to higher ratio of strength vs. weight and stillness vs. weight, various magnesium alloys are well applied in much weight saving design applications though extrusion or die-casting process. However for the requisites of higher strength and weight savings, some new fabrication processes has been and it can be realized though the aid of injection modeling technology. To obtain the parametric data base for the injection molding process, various experiments were executed for AZ91D magnesium alloy. This paper propose the optimum condition of injection temperature, first and second pressure. the process was lined-up successfully often changing the injection unit. fluid pressure system from the conventional plastic injection molding process.

This paper is a report on the parametric study of the friction characteristics on the direct acting type OHC valve train system. The numerical simulation was performed by using the IV-TAP. Dynamic analysis by using the lumped mass method was previously performed to define the acting load. The friction characteristics were analyzed by using the partial asperity contact model. The effects of operating conditions and major design parameters on the total driving torque were investigated. From the analytical prediction, it is found that valve spring stillness, surface roughness, and base circle radius are the main factors to reduce the frictional loss on the valve train system.

Since 2000, sports utility vehicles(SUVs) occupy about 40% of domestic vehicle sales. As sports utility vehicle sales are increased the probability of crash accident between SUVs and passenger vehicles increases. Generally, SUVs are heavier than passenger vehicles and their drive height and front end stillness are higher than passenger vehicles. Because of these characteristics SUVs cause more severe injury and fatal injury in SUV to passenger vehicle head-on impact. To evaluate SUV's aggessivity to passenger vehicle, we carried out SUV to passenger vehicle head-on crash test. And finally the way how to reduce incompatibility between SUVs and passenger vehicles is suggested.

The feasibility of an oil-free, motor-driven, two-stage centrifugal compressor supported by air bump bearings is investigated. This centrifugal compressor is driven by a 75 kW motor at an operating speed of 39,000 RPM, and a pressure ratio of the compressor is set up to 4. The analysis is performed by using bearing equilibrium position, heaving stillness, Campbell diagram, unbalance response, and stability. It is demonstrated in this paper that air bump bearings can be adopted well to an oil-free, motor-driven, centrifugal compressor. Specially, Cu-coated bump bearings have enough damping force to reduce a synchronous unbalance for rigid modes of the two-stage compressor. Futhermore, this concept may be applied to the flexible rotor system such as high speed turbomachinery with a super critical speed.

The purpose of the test is to evaluate an safety which carbody structure shall be considered fully sufficient rigidity so as to load a freight car under maximum load and operating condition on line track. The test carbody is constructed by RS korea co., LTD. in accordance with KNR specfication. The test cases of the carbody is tested the vertical load and compressive load to verify the strength and stillness. The vibration test is tested for analysis and evaluation of vibration, to allow for the fact that mechanical vibration in railway vehicles have specific characteristics.

We applied digital image processing about BitMap file structure in this research and studied about digital communication system. digital record saving devices can express 'High' and 'Low' as all data. Only, digital technique that two expression methods is used into several expenditures. People and communication that are far away by development of digital technology, became smooth. We wished to make communication system taking advantage of digi-tech. This system was made for communication with disabled and normal person specially. To communication method that we are studied such BitMap file handling image communication system. The goal of this contribution is to present the overview of basic algorithms for image processing using BitMap.
