The authentication in WSN(Wireless Sensor Network) usually means the entity authentication, but owing to the data centric nature of sensor network, much more importance must be put on the authentication(or attestation) for code of sensor nodes. The naive approach to the attestation is for the verifier to compare the previously known memory contents of the target node with the actual memory contents in the target node, but it has a significant drawback. In this paper, we show what the drawback is and propose a countermeasure. This scheme can verify the whole memory space of the target node and provides extremely low probability of malicious code's concealment without depending on accurate timing information unlike SWATT. We provide two modes of this verification method: BS-to-node and node-to-node. The performance estimation in various environments is shown.

This paper covers the development process of multimedia evaluation system, especially focused on customer satisfactory factors while customers navigating net-based Interactive multimedia system. Customers usually experience new level of interaction cased by newly developed web-based technology In ordinary multimedia system. However, if it gives customers satisfactory experience is a matter of question. To find out the relationship between customer satisfaction and interactivity factors exposed by multimedia system, a model has been developed which describes the structure of web-based multimedia system and its relation to customer satisfactory factors. Five different experiments, including 'semantic differential', 'focus group interview', and 'expert review', has been conducted and four customer satisfactory factors were identified.

Huge growth in developmental level, new accomplishment, and The period of adolescents is not only the transition stage but also improvement of academic level. In this level of stage, adolescents have difficulties in development, so they show psychological abnormality such as stress and depression. They could develop mental disorder such as depression or anxiety if they do not overcome the abnormality. According to the situation of the insufficiency of the decent program for adolescents' mental health in the current society, we are strongly requested to develop the psycho-therapeutic program for them. Therefore, in this study, we examined the effect of the musical activities as blues music structure on the improvement of the Self-Efficacy in the female middle school students who have depressive tendencies as well as what they experienced through the activities. The 3 participants were selected out of 70 students in the first year at the "D" middle school in Seoul by being tested with Child Depression Inventory(CDI) and Self-Efficacy Scale(SES). The musical activities were built with 3 steps. Of which, the first one was the introduction to each other, the formation of rapport, and induction of their interests to the musical activities through blues. The second one was letting participants learn the blues music structure by practice and play assigned music(including improvisation) during later 5 sessions with different difficulties at each session. The third one was giving them opportunities to play a music out of the acquired ones during the session or creative music by their own, which results in maximizing musical activities and an acquired experience. As a result, first of all, the scores of CDI test of 3 participants in 10 time sessions showed slight changes, suggesting the negative correlation between CDI and SES even though changes were not big differences. Secondly, the scores of SES test of 3 subjects in 10 time sessions were all changed and especially preference for tasking was significant. Thirdly, the scores of SES for musical playing test of 3 participants in 10 time sessions were all changed and especially preference for musical tasking was significant shown. Finally, according to answers of 3 participants in 10 time sessions for the after questionnaire on musical activities, participants experienced affirmative self-confidence and positive emotion. Taken together, it was suggested that musical activities using blues music structure could be promising therapeutic intervention method.
