This paper describes a video exchange project between English classes in South Korea and in Japan. Korean and Japanese students worked in groups to make short videos in English which were then exchanged. After viewing their counterparts' videos, students e-mailed feedback to each other. This project was the third video exchange project between Korean and Japanese university students since 2001. However, it was the first time to try it with three universities together. Students from the different universities tried to compete with each other. It provided a better chance for students to improve their English. Most students expressed the importance of the video exchange project in developing their English proficiency and enabling them to use English in an international context. Many students agreed that the project was an educational, enjoyable and worthwhile experience.

This paper has an aim to examine English native speakers' requests, and offer an instructional technique to develop EFL students' pragmatic ability. For this purpose, English-speaking native speakers' requests were collected in six different face-threatening situations, and analyzed in three ways: directness levels, internal modification and sequence of request. The analysis of requests showed that they were realized mainly through conventionally indirect level in most situations, were internally modified frequently through the use of downgraders, and had a certain sequence of utterances realizing a request. On the basis of these findings, two kinds of interactional activities (Jigsaw and pair work) were provided as sample activities to promote EFL students' pragmatic knowledge about the appropriate ways of making requests given the fact that pragmatic errors can be more serious and more problematic than grammatical errors in social interaction.

The soccer robot system consists of multi agents, with highly coordinated operation and movements so as to fulfill specific objectives, even under adverse situation. The coordination of the multi-agents is associated with a lot of supplementary work in advance. The associated issues are the position correction, prevention of communication congestion, local information sensing in addition to the need for imitating the human-like decision making. A control structure for soccer robot is designed and several behaviors and actions for a soccer robot are proposed. Variable zone defense as a basic strategy and several special strategies for fouls are applied to SOTY2 team.

Using content analysis this study examined Korean people's traditional view on children with disabilities, hoping to contribute to the selection of appropriate picture books for an understanding of disabilities in kindergartens and child care centers. Story book characters with disabilities mainly interacted with their families and village people, had lower positions, did not accomplish their work on their own, and suffered from others' anger and beating. Differences in types of disabilities were that physical disabilities were viewed positively, while mental disabilities were viewed negatively. The former had wider scope of activities and maintained more positive relationships with other characters than the latter; furthermore, the former had higher position than the latter and had cooperative interactions with people without disabilities.

This paper presents the implementation of an integrated messaging gateway (IMG) based on the open services gateway initiative (OSGi) specification to deliver home messages between home and some telecommunication devices. The IMG has four service agents to support a diverse communication channel. In this paper, we describe a software architecture for a seamless messaging and device layouts in the IMG. And then, we detail each components allowing users to be notified automatically through a cellular phone, a telephone, and the Internet.

Quality of Service (QoS) and fairness considerations are undoubtedly essential parameters that need to be considered in the design of next generation scheduling algorithms. This work presents a novel game theoretic cross-layer design that offers optimal allocation of wireless resources to heterogeneous services in Orthogonal Frequency Division Multiple Access (OFDMA) networks. The method is based on the Axioms of the Symmetric Nash Bargaining Solution (S-NBS) concept used in cooperative game theory that provides Pareto optimality and symmetrically fair resource distribution. The proposed strategies are determined via convex optimization based on a new solution methodology and by the transformation of the subcarrier indexes by means of time-sharing. Simulation comparisons to relevant schemes in the literature show that the proposed design can be successfully employed to typify ideal resource allocation for next-generation broadband wireless systems by providing enhanced performance in terms of queuing delay, fairness provisions, QoS support, and power consumption, as well as a comparable total throughput.

The supply chain in plant construction project can be defined as a network combined between elements which is engineering, procurement, construction, start-up. For successfully leading construction project, close relation and mutual cooperation should be preceded and Supply Chain Management(SCM) system is needed to improve the relation. In particular, because safety is a top priority for the companies work in the construction of Nuclear Power Plant(NPP), it is necessary to control all parties realated with NPP construction systematically. In this situation, it is important to purchase high-quality equipment in timely manner by developing Integrated cooperative systems. Therefore, this study aimed to propose developing solutions of SCM such as JIT and Envelop Design system, which can reduces difficulties of decision making between the parties involved in the project and will increase the efficiency of the engineering process in NPP.

The overall goal of this study is to identify what I'||'&'||'R is, and what services should be offered as legitimate I'||'&'||'R actives. The gist of the study is as follows: 1. The shift of the clients targeted to receive the services from disadvantageous to every person. 2. Ambiguity in I'||'&'||'R definition. Because it is hard to distinguish I'||'&'||'R service from the traditional reference service, and shifting of clients, the establishment of the definition was very difficult. Instead of a definite answer, the criteria for "I'||'&'||'R Providers" was drawn. 3. Most provided services were simple and complex information giving based on resource file. Constructing resource file is a major component of I'||'&'||'R service. 4. From 1980s, many I'||'&'||'R providing libraries adapted computer a n.0, pplications. 5. Social work and library-internship was advised to conduct a cooperative project by NCLIS, I'||'&'||'R Task Force. 6. In the high technological era, there continue to be many people who need the su n.0, pportive relationship. I'||'&'||'R is to optimize both the service and clients. Librarian must learn from the principle of high tech/high touch.

The telemedicine & distance education system that this paper suggests has been designed on the CTE(Collaborative Telemedicine & distance Education) framework, which is an integrated multimedia environment. This is a CBM-based collaborative telemedicine & distance education type, different from the conventional doctor based general practice, and is an integrated multimedia telemedicine & distance education system capable of many application developments using information super highway. This paper presents the content regarding electronic medical examination chart and data treatment for efficient medical examination and prompt treatment by realizing mutual conversation type remote medical examination system among 3 parties(patient, doctor, pharmacist) on internet base. And, The implementation of this new teaming system should be designed with multimedia application development platform base which is interfaced with computer engineering, computer network technology, CSCW (Computer-Supported Cooperative Work) technology, and education engineering.
