Currently, finding one's way in the underground spaces associated with subway stations in large cities is becoming a serious problem, and an environment that facilitates wayfinding is becoming more important. This study investigated interior treatments that function as visual cues in the subway stations of Seoul, Tokyo, and Taipei in order to develop design guidelines that would improve the place-cognition environment. A theoretical study has shown that there are three categories of visual cue for place cognition: marked trails, regional differentiation, and landmarks. The case study showed that marked trails involve treatments like vertical markers, confrontational positioning, and subway color codes. Regional differentiation involves patterns on the floors and walls, and accent colors on the walls and columns. Landmarks include treatments such as super graphics, symbolic features, artistic decoration and special lights. In the cases of Seoul, marked trails and regional differentiation were predominant. In addition, the Olympic symbol 'Hodori' and the ancient Korean character "Hunminjungeum" were used as landmarks. In the cases of Tokyo, regional differentiation predominated over marked trails because of the complexity of the spatial structure and subway line connection system. In the cases of Taipei, simple, unified images predominated, and there was minimal dependence on marked trails and landmarks. The need for regional differentiation was weak, because the stations studied have open structures that guarantee an open field of view. The results of this research could be used as design guidelines, after further experimental verification, that would help to improve the public environment in terms of wayfinding.

With the development of information technology, users are provided with information they want through mobile device in various situations. When users communicate with information, there is interaction through gesture activities such as tapping and experience in the process. Experience through interaction in mobile affect the user's psychology. This is important because it is related to the behavior of the user in the future. Various types of information presentation methods have been researched in mobile environment. However, there are more research focusing on functional interactivity. The purpose of this study is to investigate the effect of interaction and usage mode on satisfaction, usefulness, and intention to use for sound text presentation that is user-centered. As variables for my study, there are two factors which are interactivity and usage mode. The interactivity type is composed of two ways that are: High and Low depending on modality and message interactivity; and the usage mode is composed of Action mode and Goal mode depending on whether user has a task or not. The experimental design is $2{\times}2$. The same content is provided in (a) only Modality interactivity, and (b) Modality and Message interactivity are provided. Depending on usage mode, (a) Action mode is processed without a specific task, and (b) Goal mode is performed with a specific task to participants. The experimental study demonstrated that there is a difference in satisfaction, usefulness, and intention to use depending on the difference of interaction and usage mode when providing information in mobile environment. The results of this study are summarized as follows: interaction and usage mode have significant influence on mobile user's satisfaction, usefulness, intention to use.

영화 스토리 연출에는 감독의 의도에 의한 많은 장치가 숨겨져 있고, 그에 대한 분석이 필요하다. 본 연구는 성공적으로 제작된 영화의 연출 기법들을 분석하여 스토리 상황을 도출해 보았다. 1:1 대화 장면은 영화의 스토리를 이끄는 갈등이 많이 등장하는 장면이다. 그로 인해 인물들 간의 관계는 화면의 비대칭성으로 드러날 수 있다. 이를 근거로 다양한 연출 기법 중 배우의 위치, 클로즈업, 지시벡터를 우선적으로 분석하였다. 그 결과 갈등조장자에 대한 역할과 갈등 종류에 따른 차이점이 발견되었고. 이것은 두 인물의 갈등 상황을 표현하였다. 이에 따라 연출 기법과 인물 관계 표현의 법칙이 발견될 것이라 보고 있다.

To develop a cognitive system with the flexibility and breadth of human, it's very important to construct a large scale knowledge base which include commonsense knowledge as well as expert knowledge. Efficient knowledge representation and reasoning techniques will play a key role for this. This paper introduce a cognitive system which is based on Cyc knowledge base and augmented with our work on qualitative and spatial representation and reasoning. Our system has been implemented and tested on various examples.

There exist many real situations that statistical decision problems are classified into more than two categories. In these cases, the concordance statistics by the pair approach are mostly used. However, the expression of the classification of categories are ambiguous. Recently, the standardized evaluation data and re-expressed concordance statistics are defined and could be explained their meanings. They have still some non-specific problems for standard criteria of the statistics. Since these can be considered between result and truth categories additionally, two alternative concordance statistics might be proposed in this paper. Some advantages are founded that the proposed statistics could be discriminated all possible cases for two randomly selected categories. Moreover since the proposed statistics are represented with indicator functions, these could be transformed non-parametrically, so that these concordances are used for hypothesis testing.

Variable Message Format(VMF) is a communications protocol that allows computers to exchange tactical military information over low-data-rate bearers. VMF is designed to define message length and structure variably in order to allow the user to transmit only the relevant information by using indicators. However, flexibility of messages makes it difficult to analyze messages structure and figure out meanings. Furthermore, whenever messages are added or modified, message processing software should be updated and distributed to systems. In this paper, we propose a systematic approach to defining VMF messages that uses the international standard notation ASN.1. By describing VMF messages in ASN.1, protocol architects can deal with VMF messages accurately and conveniently, and use various ASN.1 tool. This paper develops ASN.1 description templates for VMF message segments, and presents an approach to describing VMF messages in ASN.1 by combining the templates.
