도시의 얼굴을 만드는 건축가 민성진. 기존의 형태를 탈피하지 못하고 구태의연하게 모방한 것이라면 이미 죽은 건축물이나 다름없다고 당당히 말하는 그는 모험과 실험 정신으로 늘 새로운 것을 시도한다. 건축가 민성진을 그가 디자인한 압구정동 SDA 건물 3층의 SKM 사무실에서 만났다.

Distance learning makes it possible for educational consumers to study anywhere or anytime. In order to provide effective distance learning, it requires not only educational process and educational results to be closely correlated but also a method for teachers and students to communicate immediately. We devised a dialogue system like a chatting program containing an editor. With this program, students can learn a programming practice by chatting between a teacher and a student. We also incorporated a source code visualization technique based on diff algorithm so that the visualization technique makes it possible for students to recognize the remedies by teachers visually. The result comes by mixing the merits of a dialogue system giving a close interrelationship among users into a programming language education. We expect that the successful result would be tantamount to a face-to-face education.

Since the advent of 3D and UHD contents, demand for high-quality panoramic images has been increasing. The UWV(Ultra-Wide Viewing) service uses a wider viewing angle than conventional panoramas to provide a lively experience for users and enhance their understanding of the event. In this paper, we propose a spatial adjacency map generation method and an UWV file storage format technology to provide UWV service. The spatial adjacency map measures the similarity between images and generate the position information of the images based on similarity. And the stitching time of the image can be shortened through the generated position information. Through the spatial adjacency map, we generate the large screen content quickly. The UWV file format which is based on ISOBMFF process spatial adjacency map and videos and support random access. In this paper, we design the UWV player to verify the spatial adjacency map and UWV file format and show the result of experiments.

The previous study has assumed that dialogue and debate could not have been activated by the hierachical Confucian norm and political authoritarianism in Korean society. Political democracy has developed in Korean society since 1987. But many observers have pointed out that the culture of debate still remained undeveloped in Korean society. This study assumes that the key factor of determining the quantity and frequency of debate is the polilitical factor such as authoritarianism, but the determining one of qualitative dimension such as debate competence derived from the epistemological tradition. In order to ascertian this hypothesis, this study explored the epistemological basis of Confucian thoughts in comparison with the classical Greek thoughts. In classical Greek society, philosophers considered that the purpose of debate is to find and to ascertain the truth. Bur Confucian scholors didn't look upon questioning the truth. Instead they considered practicing or doing of the truth worthful. Therefore, in a society which were much influenced by the Confucian thought, the culture of debate could not have been developed.

Abstract In this paper, we describe client/server puretone audiometer supporting video chat. Our system makes it possible for one audiometrist to concurrently assess multiple subjects. An audiometrist in remote place can monitor assessment procedure through video and/or result of each assessment step. This system also provides a video chat facility to lead audiometrist without a hitch whenever there occurs any problem during assessment. The one-to-many model of this system makes subjects to reduce not only expense but also waiting time.

Garbage collection in the CLDC typically employs a stop-the-world GC algorithm which is performing a complete garbage collection when needed. This technique is unsuitable for the interactive Java embedded system because this can lead to long and unpredictable delays. In this paper, We present a garbage collection algorithm which reduces the average delay time and supports the interactive environment. Our garbage collector is composed of the allocator and the collector. The allocator determines the allocation position of free-list according to object size, and the collector uses an incremental mark-sweep algorithm. The garbage collector is called periodically by the thread scheduling policy and the allocator allocates the objects of marked state during collection cycle. Also, we introduce a color toggle mechanism that changes the meaning of the bit patterns at the end of the collection cycle. We compared the performance of our implementation with stop-the-world mark-sweep GC. The experimental results show that our algorithm reduces the average delay time and that it provides uniformly low response times.

Nowadays, many research have been conducted on robots or interactive characters that properly respond to the users affection. In this paper, we develop an intelligent messenger that provides appropriate responses to text inputs according to user's intention and affection. In order to properly respond, the intelligent messenger adapts methods to recognize user's speech act and affection. And it uses an AIML-based interactive script to which tags are additionally attached to express affection and speech act. If the intelligent messenger finds a proper reply in the interactive scripts, it displays the reply in a dialog window, and an animation character expresses emotion assimilated with a user's affection. If the animation character is synchronized with a content robot through a wireless link, the robot in the same space with the user can provide emotional response.

As the AI speaker market is growing rapidly in recent years, the competition for the preoccupation of children who are the main users and the future prospective customers of the related companies is very intense. However, there is a lack of empirical research on how children interact with AI speakers. Therefore, this research examines the interactions between children and AI speakers, primarily through field studies, to extract what functions they use and what features they have. For this purpose, 799 conversations were collected and analyzed using the log data of the AI speaker recorded in real time. As a result, children were more likely to use children's songs, fairy tales, emotional conversations, and personification compared to adults. In addition, content analysis by specific types resulted in success/failure cases of interaction between children and AI speakers and proposed improvements by failure type. This study is meaningful in that it identifies children's AI speaker preferences, content, and major conversation patterns, and provides guidelines for developing services that meet children's eye level.
