The introduction of multimedia 119-notification service utilizing smart devices causes firefighters to be more exposed to emotional labor. The purpose of this study is to investigate the effect of increased emotional labor of firemen on job satisfaction. As a result, the higher the emotional labor of firefighters is, the higher job stress (${\beta}=0.166$, p=0.000) and social support(${\beta}=0.540$, p=0.000) are. But job satisfaction tends to be lower(${\beta}=-0.136$, p=0.000). As they play an important role to protect the safety and property of citizens. their job satisfaction becomes the driving force of their duty. Therefore, we think that some systematic and substantial prevention curriculum to manage their emotional labor is required.

The purpose of this study is to suggest a countermeasure against a major cause that leads to game addiction, by grasping tendency of the actual condition for the online game use in freshmen for university and by analyzing relationship of game addiction according to factors. As a result of analyzing on relationship among sub-variables for game addiction, it could be known that the more men in gender leads to the more serious game addiction and that the longer game time given using once leads to the higher level in control loss and game addiction. Also, it was indicated that the more in group with high risk leads to the more serious in physical and mental problem. There is a suggestion that a scale related to game is developed for the expansion in counseling institution nationwide and for the preventive education targeting all the ages including undergraduates and adults as well as small children and children.

ITS(Intelligent Tutoring System) is a system that provides active and flexible tutoring conditions to learners, having adopted artificial intelligence to overcome the limitations of CAI(Computer Assisted Instruction). However, the existing ITS has a few problems; the system provides the same contents to every learner, not considering main variants of their learning and achievement, characters and levels, and therefore, it does not generate satisfactory results; the system does not offer a properly designed course schedule. Therefore, this thesis proposes ARS(Adaptive Recommendation System), founded on ITS, that provides contents designed based on the characters and levels of learners. To catch the characters of learners, the important variant for successful learning, ARS applies and embodies a module of self-assessment test. Also, it puts weighs according to the areas of learning which is different from the simplified assessment that asks for short and mechanical answers for the purpose of knowing the levels of the learners.

With the growing trends of communication- broadcasting convergence, a hybrid IPTV that supports both IP network-based on-demand media and terrestrial or cable-based broadcast media is gaining attraction. This paper proposes a rich media framework for hybrid IPTV with support of the latest H.264 codec. For this purpose, we design and implement a media component and a RIA run-time engine customized for TV with the hybrid media. The media component has been designed to provide a uniform and efficient application interface to the various playback methods for RF broadcast and IP-based stored or live media. For performance and portability, it exploits media stream abstraction, adaptive on-demand I-frame search, and automatic calculation of play duration. Based on the proposed media interface, we develop a RIA run-time prototype. It has been carefully designed to fully utilize the built-in graphic acceleration hardware for optimized rendering in the resource-constrained IPTV environments. Demonstration and experiment results validate the performance and usefulness of the developed framework. The framework is expected to be used effectively to support graphics and hybrid media in the applications of IPTV-based VOD, advertisement, and education.

Most of the online learning systems provide information that is based on the item difficulty what is custumized to learner. And the same learning process is performing to the same learning level learners. But, the degree of understanding of the same learning contents can be different even if the learner's level is same. Therefore, it is difficult to represent an effective learning experience because the learning is progressed by the determined difficulty of learning and the learning process even thought the provided content is difficult to understand. So we can control the learning difficulty during learning in order to escape from a uniform learning that online learning is provided. In this paper, we proposed a contents reorganization method for Self-Directed Learning. In this way, learners can understand their own level and customize the difficulty of learning. And then we expect the higher learning effect and satisfaction degree.

A survey method in Korea has being developed rapidly since a survey company was established in 1968. In latest, the CATI, internet survey, Notebook, PDA survey methods are being utilized in accordance with communication development. This article focuses on the practical use and the strength and weakness of the PDA survey solution which employs 'KISS' system designed by KRIVET itself. The survey using PDA has, on the one hand, such strengths as follows : 1) efficient field control, 2) reduction of time for verifying data and generation of proper data 3) shortening survey duration from intial survey to data completion, 4) cutting down survey personnel and cost. On the other hand, survey using PDA has the following weakness: 1) limitation of questionnaire expression, 2) increasing time for survey, 3) communication barrier in some regions.
