At a time of emphasized need for user-oriented design, methods such as Post Occupancy Evaluation are being used to measure the exact demands of the users. The conventional methods, however, have mostly been conducted based on questionnaires printed on paper, which has posed numerous problems in researches designed to measure the visual demands. Along with the continued development of the internet and computer media, there have been examples of interactive media applications as a means of improving the existing paper-based research methods. This study is a follow-up to the primary study that unveiled cautious variances of the media. 200 samples of media-based researches were extracted to be used in analysis of in-depth visual demands. 200 housewives from rural Iud development zones, who exercises the most influence in household purchases in these regions where the problem of rate of distribution Is coming under the limelight, were chosen as the subjects. The subjects were selected from land development zones of Gimhae-si and Haeundae. At first, the research was prepared as a web-based endeavor but it employed direct research of field personnel in consideration of that this research is in the beginning. This follow-up study deals mainly with the visual demands for which cautious variances were detected in the primary study and includes analysis of mainly ground Plan layout, space coloration, livingroom utilization, and vlsual composition of LDK. Media research had the advantage of zero rate of questionnaire error due to a pre-programmed search routine, and it was possible to ascertain the actual trade-off basis demands of the residents in terms of ground plan layout. In addition, whereas conventional research methods based on still images were susceptible to the preconceptions of the respondents, the interactive media allowed for easy understanding of the spatial layout and thus made it possible for all respondents to provide answers under the same conditions.

I developed a computer program that can be used in studying the human anatomy. The program not only displays anatomical images, but also it gives some questions about the name of organs in the human body and evaluates tile answers. The program helps students scrutinize the detailed human anatomy by providing a way of interactive zooming anatomical images. To make the program more useful, better anatomical images need to be collected, and a context-sensitive search-and-view facility should be equipped with.

TCTP is presented to have a retinol binding protein (RBP)-like structure by domain search. Human cellular RBP (CRBP) plays a key role in the intercellular transfer of retinol. Modulation of its expression is known to contribute to tumor growth and progression via retinoid-mediated signaling. Changes in the expression of TCTP have also been reported to be associated with carcinogenesis. Therefore, the attempt to establish the interactive relationship between the human TCTP and CRBP with retinol will be helpful in further understanding the cell signaling of TCTP. (omitted)

The optimization of many engineering design problems requires a nonlinear programming algorithm that is robust and efficient. A general-purpose nonlinear optimization program IDOL (Interactive Design Optimization Library) is developed based on the Augmented Lagrange Mulitiplier (ALM) method. The ideas of selecting a good initial design point, using resonable initial values for Lagrange multipliers, constraints scaling, descent vector restarting, and dynamic stopping criterion are employed for computational enhancement to the ALM method. A descent vector is determined by using the Broydon-Fletcher-Goldfarb-Shanno (BFGS) method. For line search, the Incremental-Search method is first used to find bounds on the solution, then the bounds are reduced by the Golden Section method, and finally a cubic polynomial approximation technique is applied to locate the next design point. Seven typical test problems are solved to show IDOL efficient and robust.

This paper describes CAD tools for the construction of image database in IC chip analysis CAD system. For IC chip analysis by high-resolution microscopy, the image database is essential to manage more than several thousand images. But manual database construction is error-prone and time-consuming. In order to solve this problem, we develop a set of CAD toos that include image grabber to capture chip images, image editor to make the whole chip image database from the grabbed images, and image divider to reconstruct the database that consists of evenly overlapped images for efficient region search. we also develop an interactive pattern matching method for user-friendly image editing, and a heuristic region search method for fast image division. The tools are developed with a high-performance graphic hardware with JPEG image comparession chip to process the huge color image data. The tools are under the field test and experimental resutls show that the database construction time can be redcued in 1/3 compared to manual database construction.

As the artificial intelligence technology has developed recently, researches on chatbots that provide information and contents desired by users through an interactive interface have become active. Since chatbots require a variety of natural language processing technology and domain knowledge including typos and slang, it is currently limited to develop chatbots that can carry on daily conversations in a general-purpose domain. In this study, we propose an artificial intelligence chatbot that can provide real-time public traffic information and route information. The proposed chatbot has an advantage that it can understand the intention and requirements of the user through the conversation on the messenger platform without map application.

Background: The present study used magnetoencephalography (MEG) to investigate the neural substrates for modified version of Treisman's visual search task. Methods: Two volunteers who gave informed consent participated MEG experiment. One was 27- year old male and another was 24-year-old female. All were right handed. Experiment were performed using a 306-channel biomagnetometer (Neuromag LTD). There were three task conditions in this experiment. The first was searching an open circle among seven closed circles (open condition). The second was searching a closed circle among seven uni-directionally open circles (closed condition). And the third was searching a closed circle among seven eight-directionally open circles (random (closed) condition). In one run, participants performed one task condition so there were three runs in one session of experiment. During one session, 128 trials were performed during every three runs. One participant underwent one session of experiment. The participant pressed button when they found targets. Magnetic source localization images were generated using software programs that allowed for interactive identification of a common set of fiduciary points in the MRI and MEG coordinate frames. Results: In each participant we can found activations of anterior cingulate, primary visual and association cortices, posterior parietal cortex and brain areas in the vicinity of thalamus. Conclusions: we could find activations corresponding to anterior and posterior visual attention systems.
