본 연구는 이용자가 어떤 접근 점을 사용하여 온라인 목록을 탐색하며, 온라인 목록의 초기화면의 구성에 대하여 조사하는데 그 목적이 있다. 노티스 시스템과 다이닉스 시스템이 비교되었으며, 데이터는 $"2\times2"$ 의 설계로 수집되었다. 연구 결과, 초기화면의 형태가 이용자의 접근점 선택에 영향을 미치며, 특히 접근점의 배열과 세분화가 이용자의 탐색행태에 변화를 주는 것으로 나타났다. 위 결과는 온라인 목록의 설계에서 초기화면에 이용자에게 접근점 선택 없이 탐색어만 입력하도록 하고, 탐색 결과화면에서 검색된 자료를 제시하여 이용자가 관련된 필드를 선택하게 하는 방법이 제안되었다. 이 방법은 이용자가 잘못된 접근점을 선택하였을 때 발생할 수 있는 실패를 제거할 수 있을 것이다.

The purpose of this study is to investigate and suggest nonviolent, emotionally and helpful games for young people. In this paper, the digital animation, advantages, disadvantages, production process, etc. for overseas trends were defined. Also, creating games with the Visual Basic language in the animated feature of the disadvantages of existing algorithms shows case and screen time, so delayed distortion appears respectively. The proposed algorithm improves the speed and distortion through the screen. Simply two games of in-game animation and animation in complex game features were designed for the experiment and showed the superiority of the proposed algorithm by running. In this paper, the user interface of the game for children and proposed relevant algorithms were designed and resultant screens of the game showed. Most of contemporary games are violent to children. Therefore, in order to solve such problems, the game which is not violent but educative and child-friendly was designed and implemented in this paper. The future study on the game with a more in-depth is needed for animation techniques.

This study was carried out to present the pressure drop for various wind speeds through nine types of screens used in horticultural facilities. The screens have been widely used to prevent harmful insects from being entered into agricultural facilities, to reduce strong wind and to shade a light as well. Whatever the usage of the screens was, it was necessary to have good knowledge of how much the screen caused a pressure drop for wind speeds when analyzing both the inner thermal-flow distribution in the facility and the effect of reducing wind speed by using CFD. Furthermore, as for wind screens, the pressure drop for wind speeds was needed as a design load in evaluating the structural stability of the structures supporting the screens. Therefore, the pressure drop through the screens for wind speeds of 5~30 $m{\cdot}s^{-1}$ at about 5 $m{\cdot}s^{-1}$ interval and inflow angles of $0{\sim}45^{\circ}$ at an interval of $15^{\circ}$ was respectively measured in a subsonic wind tunnel. The relation of the pressure drop for various screens was well fitted as a secondorder polynomial expression.

스크린 프린트법으로 저가형 후막 용존산소 센서를 제작하고, 휴대용 용존산소 측정 시스템을 구현하였다. 전류 특성은 인가전압(바이어스 전압)을 0.7 V로 하였을 때, 응답시간도 짧고 전류 값의 변화도 가장 크다는 것을 알 수 있었다. 시스템의 구현은 MCU, 증폭단, 필터단, 전원부 및 디스플레이로 구성하였다. 용존산소 농도는 아날로그 값을 디지털로 변환하여 백분율로 표현되도록 프로그램하였다. 제작된 용존산소 측정 시스템은 표준 용액 대비 오차 ${\pm}0.5%$의 정확도 및 약 100초의 응답시간을 나타내어 고가의 상용 용존산소 센서를 대치할 수 있을 것으로 기대된다.

디지털 음성 도서는 독서장애인의 독서 환경 개선을 위해 개발되었다. 그러나 기존 디지털 음성 도서에서의 어노테이션 기능(도서에 노트나 하이라이트 등의 주석을 표기하는 행위)은 시력을 필요로 하는 화면 인터페이스를 통해서만 가능했기 때문에 독서장애인들에게는 무용지물이었던 것이 사실이다. 이에 본 논문에서는 듣는 능력과 음성만으로도 노트나 하이라이트 달기 같은 어노테이션 기능을 가능하게 해주는 음성 어노테이션 기법을 제안한다. 디지털음성도서 재생 중 입력된 음성 어노테이션이 어느 문장에 해당하는 것인지를 결정하는 기법을 설계하였으며, 이의 효용성을 검증하기 위해 안드로이드 환경에서 구현하였다. 눈가리개를 착용한 복수의 실험자들을 대상으로 실험한 결과 실험자들이 의도했던 위치에 정확히 어노테이션이 삽입된다는 것을 확인하였다.

Objective: The aim of this study is to propose the contactless gesture-based interface on smart mobile devices for especially rhythm action games. Background: Most existing approaches about interactions of smart mobile games are tab on the touch screen. However that way is such undesirable for someone or for sometimes, because of the disabled person, or the inconvenience that users need to touch/tab specific devices. Moreover more importantly, new interaction can derive new possibilities from stranded game genre. Method: In this paper, I present a smart mobile game with contactless gesture-based interaction and the interfaces using computer vision technology. Discovering the gestures which are easy to recognize and research of interaction system that fits to game on smart mobile device are conducted as previous studies. A combination between augmented reality technique and contactless gesture interaction is also tried. Results: The rhythm game allows a user to interact with smart mobile devices using hand gestures, without touching or tabbing the screen. Moreover users can feel fun in the game as other games. Conclusion: Evaluation results show that users make low failure numbers, and the game is able to recognize gestures with quite high precision in real time. Therefore the contactless gesture-based interaction has potentials to smart mobile game. Application: The results are applied to the commercial game application.

Recently, much attention has been paid in the field of defrosting because clear windshield in vehicle without effecting the thermal comfort is realized essentially. Then in winter, defrosting performance is one of the important factors in vehicle design to make certain driver's view. In this study, the velocity profile, temperature distribution and frost melting pattern on the windshield screen have been predicted in three dimensional geometry of an automobile interior. Numerical analyses predict a detailed description of fluid flow and temperature patterns on the inside windshield screen, utilizing the flow through defroster nozzle. Numerical prediction established a good defrosting performance with the standard distance ratio and the defroster nozzle angle ranging from $30^{\circ}$ to $40^{\circ}$, which satisfy the condition of National Highway Traffic Safety Administration (NHTSA) completely.

The Platform Screen Door system(PSD) is scheduled to be installed on the platform of some subway stations in Seoul, Pusan, Kwang-Ju, Daejun and Daegu and all stations of Seoul Subway No 9. will equipped with PSD. On the other hand Seoul Metropolitan Rapid Speed(SMRT) that has operated the train automatically had finished the basic desic design and the execution drawing of PSD and installed successfully the PSD on the platforms in the Kimpo Airport station in Subway Line No 5. at dec. 2005. The exhibition operations of PSD has made the major contribution to build up the safe and optimum subway for the increasing customers. Nowadays PSD has operated on ATO sections and ATS sections. But in the case of closing the door manually in ATO sections, it would be delayed about 5 seconds in closing the door of PSD. Although the interface of PSD, train and the signal system is established automatically, we have to supplement technically on the interface between train, PSD and the ground signal interface equipments. Therefore I will center on the optimizing methods about the interfacing system between the train and the PSD, train and the signal system to overcome the above problems in this study.

The current study examined the influence of individual trait such as Need-For-Touch level (NFT; high vs. low) and swiping orientation (vertical vs. horizontal) on product evaluation and preference when using touch-screen interface like a smart phone and a tablet. Swiping is one of the most common interaction techniques for changing pages or searching some aligned pictures on touch-screen interface and it can be used in vertical and horizontal orientations. The experiment revealed a significant interaction between swiping orientation and NFT on preference, however the interaction on change-in-price of given products was only marginally significant. To be specific, high NFT participants reported higher preference for horizontal-swipe than vertical-swipe products, but such difference did not occur with low NFT participants. The current study illustrates the influence of swiping orientation and NFT on product preference and it provides a new perspective of design principles especially for online shopping websites.

Standard crystalline solar cells are generally fabricated with the front grid pattern of silver paste contact. We have reported a detailed theoretical analysis of the proposed segmented cross grid line pattern in this paper. This work was carried out for the optimization of spacing and width of grid finger, main busbar and sub-busbar. The overall electrical and optical losses due to front contact were brought down to $10\%$ or even less as compared to the usual loss of $15\%$ or more in the conventional screen printed silver paste technology by choosing proper grid pattern and optimizing the grid parameters. The total normalized power loss for segmented mesh grid with plated metal contact was also observed and the total power loss could be brought down to $10.04\%$ unlike $11.57\%$ in the case of continuous grid and plated contact. This paper is able to outline the limitations of conventional screen printed contact.
