There has been a number of attempts to apply 3D CAD data created in the design stage of product life cycle to various applications of the other stages in related industries. But, 3D CAD data requires a large amount of computing resources for data processing, and it is not suitable for post applications such as distributed collaboration, marketing tool, or Interactive Electronic Technical Manual because of the design information security problem and the license cost. Therefore, various lightweight visualization formats and application systems have been suggested to overcome these problems. However, most of these lightweight formats are dependent on the companies or organizations which suggested them and cannot be shared with each other. In addition, product structure information is not represented along with the product geometric information. In this paper, we define a dataset called prod-X3D(Enhanced X3D Dataset for Web-based Visualization of 3D CAD Product Model) based on the international standard graphic format, X3D, which can represent the structure information as well as the geometry information of a product, and propose a translation method from 3D CAD data to an prod-X3D.

This study attempts to evaluate the Korean terrestrial television networks‘ internet site effectiveness, specifically in addressing user motivations and user evaluations and in gauging the broadcasters' feedback. The result shows that the primary motive for using a broadcaster's internet homepage was to obtain information. Overall, the users tended to be dissatisfied with the services, especially with regards to its navigational structure and design and with the insufficient number of appropriate content items. The reason cited highest for dissatisfaction was the fee-based services. Among the three networks, Seoul Broadcasting System, the sole commercial network, received the most complaints from the respondents in this respect. The study results reveal that broadcasters' feedback systems to users were deemed responsive and timely, but a true interactivity between the broadcasters and the viewers was lacking. In conclusion, network televisions' internet sites and increased content access through them have provided a platform for increased communication with their viewers, however, these sites are not yet being fully utilized as effective interactive communication feedback channels but more as a unidirectional information source. In addition, the network television services seem to be lacking in providing users with efficient navigational structure, good design, or adequate content level and quality. Thus, to better serve the public, it is recommended that they improve internet homepage usability by assessing and applying qualitative researches regarding the users.

Interactive intervention of the human presenter is one of the important factors that make the visualization more effective. Rather than just showing the content, the presenter enhances the process of the information delivery by providing the context of visualization. In this paper, we define this as an augmented presentation. In augmented presentation concept, the presenter can facilitate presentation more actively by being fully immersed in the visualization space and reaching and interacting into digital information. In order to concrete the concept, we design presentation space that enables the presenter to be seamlessly immersed in the visualization. Also we increase the presenter's roles as a storyteller, controller and augmenter allowing the presenter to fully support communicative process between the audience and the visualization. Then, we present an augmented presentation system to verify the proposed concept. We rendered 3D visualization through a half-mirror film and a wall projection screen that are place in parallel and applied with stereoscopic images, then, spatially align the presenter inside the virtual visualization space. After that, we conduct a controlled experiment to investigate the subjective level of immersion and engagement of the audience to HoloStation compared to traditional presentation system. Our initial investigation suggests that the newly conceived augmented presentation has potential not only to enhance the information presentation but also to supports the delivery of visualization.

This study aimed to examine the effects of a reciprocal attention intervention on the joint attention behaviors of children with autism spectrum disorder (ASD) by comparing the music and nonmusic conditions. An alternating treatment design was applied as one of the single subject designs and the reciprocal attention intervention included music and nonmusic conditions implemented alternately within a session. The participants were four children between the ages 4 and 5 years and each participant who participated in 23 intervention sessions that followed the sequence of baseline (3 sessions), treatment (15 sessions), and follow-up (5 sessions). The music condition consisted of structured joint instrument playing, trials for attentional shift, and interactive instrument playing. The nonmusic condition consisted of joint toy play, trials for attentional shift, and turn taking-based play. The occurrence of target behaviors (i. e., joint attention behavior, eye gaze, and joint action) was analyzed across sessions. At pretest and posttest, the Early Social Communication Scale was administered. All participants showed increasing tendency in all target behaviors, but such occurrence was greater in the music condition than in the nonmusic condition. The findings support the use of a reciprocal attention intervention with musical stimuli to effectively improve joint attention in this population.

There has been an increasingly high interest in gardens and garden design in Korea recently. However, the usage of the term 'garden' is extremely varied and complex, and there has been very little academic research made on the meaning of garden. Therefore, this research attempts to investigate the ideas of current gardens and to elucidate their changing patterns by means of extensive literature research and big data analysis. The notion of garden in the past was broad including not only private space such as Madang(마당) and Teul(뜰), but also even field and grass land as public outdoor space. Yet, the meaning has become smaller to merely private space due to the change of dwelling systems due to high industrial development of the 20th century. Furthermore, the introduction of urban parks as an interactive space between nature and humans, the similar spatial function of gardens, has blurred the boundary between garden and park, which created confusion in understanding the concept of a garden. After all, garden is a subject for humans. The meanings of garden need to be recognized from various points of view since garden itself is a creation by the sum of diverse fields such as natural and social sciences as well as culturology. This discussion on the meaning of garden in the present day will give a conceptual foundation for future research on gardens and garden design. Also, the big data analysis employed here as a research method can help other similar research topics, particularly semantics in landscape architecture.

Today's internet advertisement market is growing rapidly placing great importance on banner advertisements. Still, banner advertisements are being ignored by the users because most of these banners are exaggerated, visually distracted and they usually interfere with internet surfing. These banners make the agents and the users feel displeased and furthermore, make internet market unstable. 'Rich-Media'came in sight as the new way of advertising means in the internet market as the users demand for more dynamic and interactive media. In Rich-Media, sound and animation interact with former animated banner advertisements. Internet advertising businesses inducing web agencies have positive views about Rich-Media, because more information and ideas are shared through aural and visual integration and it is very effective way to draw attentions from the users. In this study, we have examined the effects of Rich-Media advertisements through surveys. As a result, Rich-Media advertisements are superior to ordinary banner advertisements in visual effect, leading interests of users, inducing mouse did(s and providing of information. The recent uses of Rich-Media is just a mere beginning, but we expect to make the Rich-Media an essential medium of internet advertisement as we continue studying the uses and effects of Rich-Media.

The purpose of this study was to find out the effect of in-service education on the nurse-newborn play interaction. The research design adopted the pre-experimental design applied only for one pretest-posttest group and Barnard's mother-infant interaction model was used as a conceptual framework. The subjects were 26 nurses who were selected from 2 nurseries in general hospital in Pusan, and 52 healthy newborns who were after 4 days from birth during data collection period at the same hospital. The data were collected from June 1st to October 5th in 2001, by video-taping for the interactive behaviors between the nurse and the newborn, played for 5 minutes in nurseries 2 weeks before and after in-service education. The in-service education consisted of the newborn's behavior responses focused on the newborn baby's states, behavior, cues and state modulation, 3 times per 1 week, 90 minutes per 1 time, lecture, demonstration and hand out project. The experimental tool used for this research was Ha Young-Soo's Korean translation of the Maternal-Infant Play Interaction Scale by Thompson, Jody Baird, Sara Gordman, Bryant(1982), some parts of which were adapted to be suitable for the purpose of this research. Mother and baby scale by Wolke & James-Roberts(1987) was also modified and used as the criterion of nurse's perception of a newborn baby. The results of this study were as follows: 1. This result supported the major hypothesis : After the intervention of in-service education, the nurse and newborn play interaction was promoted. 2. After intervention of in-service education, the nurse perception of newborn, especially the criteria of newborn's reaction was promoted., The results of this research confirm that in-service education on the newborn's behavior responses such as states, behavior, cues and state modulation is an effective way to improve the interaction between the nurse and the baby. It elevated the nurse's sensitivities to the baby's needs. Therefore, in-service education can change the conditions of current nursing practice mostly centered on physical care into a better one in which nurses consider the emotional, social, and intellectual development stages of babies. Accordingly, in-service education contributed to promoting the effective nurse-newborn play interaction so positively.

Software streaming allows the execution of stream-enabled software on desktop or portable computing devices like PC, PDA, laptop, cellular phone, etc., even while the transmission/streaming from the server may still be in progress. In this paper, we present an efficient streaming system called Software On-Demand(SOD) streaming system to transmit stream-enabled applications in addition to automatic installation of program registry, environment variables, configuration files, and related components. In particular, we design and implement a SOD system in Linux to provide the user with the instant look-and-click software execution environment such that software download and installation are internally proceeded in a completely user-transparent way. Therefore, the SOD system relieves the user from the tricky, failure-prone installation business. In addition, the software developer now obtains a new, powerful means to advertise and propagate their software products since the user can use software packages via user-friendly UI window or web browser by look-and-click interactive operation. In the paper, we also make a couple of SOD streaming experiments using a spectrum of popular softwares. Based on the analysis of the experiment results, we also propose two performance improvement schemes.
