The purpose of this study is to find the effect of introvert-extrovert trait and smartphone using motivation on the degree of discussion flow and satisfaction at the smartphone based online discussion. The results of this study were summarized as followed : Firstly, the learner's introvert-extrovert trait affects the learner's discussion flow degree. That is, the introvert trait group was more effective than the extrovert trait group in the discussion flow degree. Secondly, the learner's introvert-extrovert trait affects the learner's discussion satisfaction. That is, the introvert trait group was more effective than the extrovert trait group in the discussion satisfaction. thirdly, the learner's introvert-extrovert trait and smartphone using motivation affects the learner's discussion flow degree. That is, the introvert trait and smartphone presence using motivation group was more effective than the extrovert trait and smartphone presence using motivation group in the discussion flow degree. lastly, the learner's introvert-extrovert trait and smartphone using motivation affects the learner's discussion satisfaction degree. That is, the introvert trait and smartphone presence using motivation group was more effective than the extrovert trait and smartphone presence using motivation group in the discussion satisfaction degree. Based on these research results, it was suggested that introvert-extrovert trait and smartphone using motivation should be utilized in order to improve the discussion flow degree and satisfaction.

In biomedical research area, various researches have been carried out to develop novel tools for analyzing biomedical interactions and relationships between compounds, proteins, genes, and diseases. In previous project, we built network of biomedical information related to herbal medicine and developed multidimensional analysis tools exploiting those relationship between data. However the previous system is not capable of building network of traditional medical knowledge of herbal medicine and analyzing it. In this paper, therefore, we aimed to expand the previous system by adopting traditional Korean medical knowledge. In order to design the expanded system, we analyzed the process of building network and user interfaces of the previous system as well as the database schema related to herbal medicine in traditional Korean medicine information portal (OASIS). The expanded system has two sided view of network. In the left side of view, there is traditional medical knowledge based network which is composed of herbal medicine, herbal prescription, efficacy, and target and provides links to the web contents of papers, prescriptions, monographs, and specimen of OASIS. The expanded K-herb network multidimensional analysis system by connecting traditional medical knowledge will be a useful network analysis tool to researchers in the traditional medical and biomedical area.

In this paper, a iterative numbering protocol(Regular Sequence Numbering Protocol) for the monitoring of demage detection sheet is proposed. Demage detection sheet is one of the social infrastructures which is constructed with underground various pipe networks. The damage detection sheet is attached to the upper part of the underground facility, and is attached to provide the damage data at an early stage when the facility is damaged. Recently, it has been developed into a form that can detect when a sinkhole occurs. It is difficult to detect the demage of such a sheet by a general electric method because the distance is long (about 1.2 Km). However, if the communication distance is secured by the RS-485 standard, which is one of the communication standards, it is possible to detect the presence of demage. In addition, the noise due to various leakage currents existing in the basement is mixed with the data for damage detection through the sheet as a medium, causing multiple data corruption. In order to solve this noise problem, we propose and design an regular sequence numbering protocol with a robustness noise immunity. The proposed protocol is designed not only to detect the demage of the sheet but also to detect the communication quality of the demage detection sheet buried in the underground. The system is constructed using the 5V based Arduino and RS-485 board as the communication embedded board at both ends of the sheet. The uploading of the final data is implemented using Wi-Fi or CDMA network.
