The purpose of this study is to identify the influecing factors on the user's satisfaction and continued usage intention in IPTV services. For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 310 users who have used IPTV and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, perceived enjoyment was confirmed to have a positive effect on user's satisfaction and continued usage intention, however, we found no evidence of a statistically significant relationship between perceived enjoyment and perceived usefulness. Second, perceived ease of use was found to positve influence perceived usefulness, however, we found no evidence of a statistically significant influece on user's satisfaction. Third, confirmation was found to positively influence satisfaction and continued usage intention. Fourth, perceived usefulness had a positive influence on continued usage intention, and both perceived usefulness and satisfaction had a positive influence on continued usage intention. Based on these findings, we suggested the implications and further research directions.

Cell division in biological education is an important and unintelligible unit. Most of students have no interest in learning the content, and don't concentrate on it because cell division unit contains relatively difficult content. In this vein, during considering the effective learning methods, the researcher found role-play as the method for student's positive access to important and unintelligent learning content. Effect of role-play on their learning achievement of science was analysed through the Chapter of cell division on 3rd grade of middle school students. For this study three levels of middle school students were selected from the school located in Seoul. And divided this students into experiment group and control group by 2 classes respectively. Before putting into practice this instruction, there took into account the before and after of students' learning achievement and their learning attitude by using same questionnaire. On the other hand, the researcher put into practice co-variate analysis by using SPSS statistical package as the measurement method.

Emerging three-dimensional television (3DTV) as a new IT product shows a possibility that television is not for just watching broadcasting, but an attractive tool for applying it to our real life. Three dimensional television is generally more effective and attractive than two-dimensional television (2DTV). But it still needs continuous technological improvement to solve its inherent limitations until many customers decide to purchase 3DTVs without hesitation. Innovative products like 3DTV encounter a quality problem leading purchase decision by customers. Quality is regarded as one of the most important factors affecting customers to adopt and use the product. Furthermore, measuring quality effectively is considerable for the 3DTV research. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for evaluating 3DTVs in a view of quality. We describe quality criteria affecting the 3DTV selection through a literature survey and develope an analytical method for measuring quality. We classify the quality of 3DTV into four types and suggest a concept of the quality ratio as a measurement criteria instead of the quality gap. Though a numerical example, we show how priorities of 3DTV with versatile manufacturers is computed.

Social network service is service that enables the human network to be built up on web. It is important to record users' information simply and establish the network with people based on the information to provide with the social network service effectively. But it is very troublesome work for the user to input his or her own information on the mobile environment. In this paper we suggested a system which classifies users' behavior using context and creates blogging sentences automatically after inferring the destination. For this, users' behavior is classified and the destination is inferred with the sequence matching method using Naive Bayes classification. Then sentences which are suitable for situation is created by arranging the processed context using the structure of 5W1H. The system was evaluated satisfaction degree by comparing the created sentences based on actually collected data with users' intension and got accuracy rate of 88.73%.

This study aims to develop the methods for effective patient flow in the medical center through simulation modeling. To achieve this, we developed three simulation scenarios based on max/min processing time and addition of X-ray by 15 patient tracks from real hospital data. The simulation software used in this study is Flexsim HC 2.7. According to the scenario 1 on 15 patient tracks' LOS by max processing time, there is a great difference between average length of stay(LOS) and max LOS. And average LOS increases greatly depending on the number of patients by the hours. There is no need to add extra X-ray because the addition of X-ray has not much influence in average LOS. It is possible to make good decisions on patient flow management and medical equipment purchasing through simulation modeling. The concrete simulation scenario as a tool for decision support will contribute to efficiency in hospital management.
