Most middle school and high school students learns under the same study plans and educational courses. Such an equal level education policies prevent the science-gifted from developing and promoting their ability. So it is severely necessary to sort out the gifted in science and make them develop their ability. In this paper, the attitudes of teachers and parents toward the science-gifted student in middle school were investigated as well as the characteristics of the gifted. One hundred science teachers of middle school who recommended the gifted in science and their parents in Seoul area were questionnaired. The follows are the consequences of investigation. 1. Most teachers and parents of the gifted considered that the school should do a special care for the gifted in science. That is, they prefer the enrichment course to the acceleration course for it. 2. The teachers play the role of motivating the study and promotion very well, but do not well as either the advisor or the cooperator with the parents because of their excessive work and lack of professional knowledgement about education of the gifted. 3. The parents play the role of the advisor or the counselor well, but do not well as the cooperator with school. 4. Among the characteristics of the gifted, there are not any differences between boys and girls in conduct characteristics. But there are meaningful difference in emotion characteristics. 5. The education of the gifted is very important for developing of country and personal promotion. So the administrative and financial support are necessary in order to sort out the gifted in science earlier and provide various programs.

Purpose Although many users change their smartphone, most may be inclined to continue using incumbent smartphone series instead of switching to new brands. Brand loyalty and switching costs are major determinants of inclinations toward incumbent smartphones. This study addresses the research question, "what roles brand loyalty and switching costs play in the purchase of new smartphones?". Design/methodology/approach A research model consisting of six hypotheses for explaining purchase intentions toward new smartphone was proposed considering inclinations toward incumbent brands. The research model was empirically tested based on purchase intentions toward the LG smartphone brand G4, employing a sample of 177 university students in Korea. The data were analyzed using the PLS technique. The results provide support for all hypotheses. Findings First, perceived inclinations toward incumbent smartphone, brand loyalty and switching costs, explained the purchase of new smartphones as well as the perception of new smartphone. Second, brand loyalty was found to play the role of moderator between switching costs and relative advantage in the purchase of new smartphone. Third, perceived aesthetics and price value had considerable influence on the purchase of brand-new smartphone.

In this paper, we propose a group playback synchronization method using adaptive synchronization delay time by the bit rate of media to synchronize a play position of streaming media between mobile smart devices. This method consists of streaming server-side and client-side synchronization algorithms based on synchronization delay time which includes connection time, control packet transmission time, streaming data buffering time, and synchronization processing time. We implement the Android media player application with synchronization support using the proposed algorithms and present the result of performance evaluation.

This paper proposes a session control model for the P2P(Peer to Peer) IPTV(Internet Protocol Television) services and presents the IPTV session control procedures based on the proposed model. Since, while public IPTV traffic is usually processed via a separate network, P2P IPTV traffic is processed together with the conventional Internet access traffic, the P2P IPTV control mechanism needs to provide multi-stream processing for the constituent TPS(Triple Play Service) traffic and corresponding QoS(Quality of Service) control functions. Besides, P2P IPTV session control mechanism should provide appropriate multicast control functions in order to support effective transmission of video traffic generated by personal IPTV broadcasters. The P2P IPTV session control model proposed in this paper is designed to be based on the standard SIP(Session Initiation Protocol), IGMP(Internet Group Management Protocol), and COPS(Common Open Policy Service) protocol so that it can contribute to the easy and prompt deployment of inter-operable P2P IPTV platform.

EJB(Enterprise JavaBeans) is the server-side component model and its purpose is to reduce the complexity of software development and to increase software reusability. Many concerns for development of EJB components have recently been raised. However, it is difficult to compose EJB components provided by third parties through the plug-and-play method. Therefore, the composition method by lego block styles is needed for EJB components. In this paper, we propose an approach to composition of EJB components using the C2 architectural style. In order to support EJB composition, we modified the general C2 architecture framework. We propose how to create EJB wrappers that can compose EJB components according to the C2 framework. Our approach also enables developers to create a new composite EJB that uses a C2 architecture which is composed of EJB components. To do this, we propose how to create a new composite EJB.

This study is about small theaters in Paris which produced the theater of the avant-garde(or theatre of the absurd) in the 50s. Paris was at the center of astonishing passion by small theaters in terms of spectacle. Small theaters actively embraced young actors/actresses, theater troupe and playwrights who created a new way to express their plays. They were mostly obscure but showed talent and genius. So playwrights came from abroad such as E. Ionesco, S. Beckett, A. Adamov and others were able to create a new type of comedy and experience theatrical realization. On the other hand, a great many drama creators such as R. Blin, N. Bataille, J.-M. Serreau, J. $No{\ddot{e}}l$ and others appeared. We focused on studying about life of small theaters in Paris as mentioned earlier. The space of representation were limited. They were mostly about ridiculing of dramaturgy of comedy and theatrical realization. The substandard situations and conditions of small theaters fell far short of advantages of spectacle. Some of the theaters - Babylone, Noctambules, Nouveau Lancry, Quartier-latin - have not been able to survive up to this day. Other Theaters - Huchette and Poche-Montparnasse - have been able to last by performing creative activities. The theaters of the avant-garde are historic places of Drama Art. It is quite astonishing that some of the monuments did not last any longer. These were the places where La Cantatrice chauve by Ionesco and En attendant Godot by Beckett were premiered. When will they be restored to their original state? Meanwhile, the theater of Huchette have performed the comedies of Ionesco for last 60 years without a break. It becomes the museum of theater of the absurd that is the cradle of modern play. In conclusion, a great many play creators like playwrights, directors and set designers saw the light of day because of small theaters when there were not enough support fund. Their passion and curiosity still make us look forward to emerging of new drama.

The purpose of this study is to investigate learner-learner dialogue during speaking tasks. In the Korean language classroom, conversation between learners is an important activity as speaking practice. However, learner dialogue is also a tool to enable learners to collaboratively conduct various cognitive activities in the classroom. In previous research, it was unfolded that through learner-learner dialogue, learners can solve second-language related problems and set a goal to carry out tasks. Therefore, this study analyzed learner-learner dialogue to investigate what kinds of cognitive activities are activated during the role-play task. As a result, the learners collaboratively generated and monitored language and content for role play. Also, in order to accomplish tasks more successfully, learners shared the same understanding about the goal of the task, and tried to manage the task procedure. Through learner-learner dialogue, learners can participate in cognitive activities such as content, language construction, and task management voluntarily without the help from teachers. This means that learner-learner dialogue can be an activity to support language learning tasks. Also, it can make learners actively involved in learning and by sharing resources with each other. It is also important that learners can experience language use that participates in real-world communication activities, such as learning in the classroom and collaborating with peer learners. This study is an exploratory study for a basic understanding of learner's conversation as a cognitive activity, and the scope of the study is limited to clarifying contents of learner-learner dialogue as a cognitive activity in speaking tasks. Based on the findings of this study, future research should be conducted on the function of learner-learner dialogue as a cognitive activity in Korean language learning and its role in the classroom of Korean language education.

The local governments have utilized overseas offices of businesses within their jurisdiction as a forward operating base to discover and expand the overseas market. In addition, overseas offices of businesses are expected to play a big role in economic, cultural, and personal exchange, and collection of information regarding overseas market trends. Recently, inviting foreign capital, promoting cities, and attracting foreign tourists are being done through them. Since foreign capital invitation has an effect on creating jobs, the population influx, increasing local government revenues, there is a high degree of competition for it among local governments. Also, while local governments have set out to actively attract foreign tourists through city promotion marketing and developing products in connection with their region, overseas offices of businesses are playing a major role in doing the job. However, due to low performance satisfaction against the budget invested, there have been criticisms that they need to improve efficiency. As a result, each local government is faced with a task to seek efficient operational plans since overseas offices of businesses in each local government are expected to play a bigger role in trade support and international exchanges.

The Universal Plug and Play (UPnP) specification permits networked devices to discover each other and to provide diverse services in the home network environment. Recently, new paradigms such as mobile connected computing, cloud-based service delivery, smart device content sharing, and Internet of Things (IoT) have emerged, but the home network based UPnP shows functional limitations in supporting such paradigms. To support them, the UPnP Forum has recently extended the capabilities of the existing UPnP, calling it UPnP+. In this paper, the UPnP Device Architecture V2.0 (UDA 2.0), which forms the basis of UPnP+, is presented. We present how UDA 2.0 enables the expansion of the home network to wide-area networks and non-IP device domains.
