As screen printing is changed by automation recently, could print more exactly. However, must suffer great many trial and error to have still gotten perfect result. By the way, at this step, fair time and money should be invested. Therefore, if search for optimum condition in early time visualizing screen printing process using simulator program before progress printing, is judged that may be correct and gets printing result efficiently. In this paper, searched optimum printing speed and ink viscosity using FLOW-3D program. Also, the result could confirm truth that is agreeing almost with experiment contents. Through this, is thought that may expect extension of screen printing wide application that vivify advantage of screen print if use simulation program.

인간은 또 다른 인간들과 관계를 맺으며 살아간다. 이러한 관계 속에서 공동체를 형성하고 공동체는 개인에게 맡은 바 임무에 충실할 것을 기대하고 요청한다. 인간은 그러한 공동체의 기대와 요구에 부응할 수 있도록 자기 자신을 바꿔 상대방으로부터 인정을 받으며 사회에서 하나의 정체성을 가진 개인으로 적응한다. 여기서 블로그는 인간과 인간을 이어주는 새로운 커뮤니케이션 수단으로써, 사회적 삶을 위해서는 필수적이다. 왜냐하면 블로그는 오프라인과 달리 몇 가지 다양한 특징들을 갖고 있기 때문이다. 물론 블로그는 순기능과 더불어 많은 역기능도 존재한다. 그 중 하나로 블로그는 다양한 감성적 정보를 상대방으로부터 제대로 전달되지 않고 있다. 따라서 본 연구는 코딩작업을 통해 블로그의 오인된 상호작용의 원인을 파악하였으며, 이것은 블로그를 본격적인 디자인 미디어로 간주하는데 매우 긴요함을 입증한다. 한편 블로그의 오인된 상호작용의 원인을 관찰자 개인의 특성과 컴퓨터 스크린 매체의 특성으로 유추하며, 이중 어느 관점에 영향력을 가지는 가에 초점을 맞춘다. 결과적으로 연구결과는 오인된 상호작용의 원인이 개인적 특성(성별)에 의한 것이 아니라 컴퓨터 스크린 매체의 특성으로 인한 것을 발견한다. 그리고 이러한 연구 결과를 토대로 앞으로 좀 더 명확한 상호작용이 이루어질 수 있는 가능성에 대한 방안에 관하여 디자인관점에서 향후과제로 제안한다.

All Humans are living in relation with each other. They form their community in this relationship, and such community expects and requests individuals to faithfully carry out their own responsibility. A person changes himself/herself in order to meet such expectation and request of the community, is recognized by others, and adopts himself/herself as an individual with identity in the society. Here, the Blog is a method of communication connecting humans, which is essential to social life. This is because the Blog has some various characteristics unlike offline. Specifically, first, the Blog enables surfing at all times and assists easy provision and communication of information. Second, the Blog has the characteristic as personal communication medium. In other word, it enables smooth communication and promotion of friendship. Third, only with use of images and texts on computer screen free from physical body, the Blog helps a person in informing himself/herself to others and enabling interaction with them.. Of course, such Blog has also adverse effects in addition to its good effects. We can point out its failure of transferring a variety of emotional information as one of such adverse effects. Therefore, this study suggests that understanding the Blog culture properly is essential in seeking a proper alternative to the adverse effect of the Blog and regarding the Blog as real design medium.. In this regard, the purpose of this study focused on which one of interactivity in individual’s properties and interactivity in media’s properties is more influenced by the cause of adverse effects of the Blog. In the experiment, 8 coders accessed the Blogs of writers and drew a conclusion through analysis on them. The results of study showed that self-expression by computer screen, a property of medium caused more misunderstandings than self-expression by face-to-face. Therefore, it is found that wrong interaction in cyber space is not due to individual’s property (i.e. gender) but is significantly influenced by screen medium itself. Furthermore, through this result, this study suggests that it is necessary to seek a way in which more definite interaction can be made in case of self-expression on the Blog as a future study in the aspect of design.

Among the various hand gestures, pointing gesture is highly intuitive, and does not require any priori assumptions. A major problem for pointing gesture recognition is the difficulty of pointing fingertip tracking and the unreliability of the direction estimation. A novel real-time method is developed for pointing gesture recognition using Kinect based depth image and skeletal points tracking. An adaptive virtual touch screen is constructed instead of estimating pointing direction. When a user stands in a certain distance from a large screen to perform pointing behaviors, he interacts with the virtual touch screen as if it is just right in front of him. The proposed method is suitable for both large and small pointing gestures, and it’s not subject to users’ characteristics and environmental changes. Experiments have highlighted that the proposed approach is robust and efficient to realize human-computer interaction based on pointing gesture recognition by comparisons.

This study aimed to investigate the difference between reading on paper and on the computer screen in L2 speakers. Based on the interrelation between computer technology and literacy, this research focused on the ways in which the computer mode of presentation may induce critical literacy. Twelve Korean students in a graduate program were randomly assigned to one of the two presentations of text, paper or computer and read a chapter excerpted from Beloved written by Toni Morrison (1987). The results indicated that the computer group read the text faster and consulted reference materials more regularly than did the paper group. The analysis of summary protocol and appreciation responses suggested that reading on the computer may have induced critical reading of the given text.

The purpose of the study was to compare the scores of Korean Evaluation Scale Hearing Handicap (KESHH) between touch-screen version (sKESHH) and paper-and-pencil version (pKESHH) questionnaires. Total 95 hearing impared listeners participated and their average age was 69.7 years old. The Group A completed the sKESHH and then did the pKESHH in 7-15 days. The Group B conducted in the reverse order. The completion time were measured. Also preference version of questionnaire was asked. Results showed that two versions of the questionnaire scores were not significantly different. Completion time of versions were not significantly different. The degree of completion was 100% in sKESHH, but it was 87% in pKESHH. The findings herein demonstrated that computerized touch-screen could be helpful to hearing professionals for collecting, assessing, and analyzing data of level of hearing loss for their patients in clinical practices.

In this paper, we propose a vision based system employing two cameras to provide effective touch screen function. The two main processes - determining touch (or no-touch) and contact location of screen plane - are essential for enabling touch screen function. First region of interest is found by using color characteristic and histogram for determining the contact mode. Second, if the hand touches the mirror, the fingertip point in image is found using the correlation coefficient based on the mirror attribute. Subsequently, the fingertip coordinate in image is transformed to the location in mirror plane by using four predefined points (termed as four-point method) and bilinear transform. Representative experimental results show that the proposed system is suited to touch screen.
