Ubiquitous computer technology (U technology) is continually, and the trend is moving towards the miniaturization of devices, cost reduction, performance enhancement, and intelligence. It is important to improve fire safety system by the application of advanced IT technologies. In this study, a vulnerable point in fire safety was selected for improvement by U technology. The structure of the whole system and a unit system was were designed. This system is divided into 5 parts: the U-fire protection facility management system, the U-fire safety information system, the U-fire safety education system, the U-fire response system, and the U-wide area fire safety management system. The prototype system was constructed in a real building to confirm the applicability of the system.

A arrival of u-teaming paradigm requires many u-teaming system and model that is varied and support to distance education, Accordingly, the distance education system in u-learning environment has attracted a fair amount of critical attention. However there remain many questions, as yet unresolved, such as it is difficult to maintain interaction between tutor and learner, the construction of system is a great expense to them, a tutor, who manages the system, lacks technologic background, in most current distance education system. To solve these problem, some preliminary observations have to be made first: to keep teaming process in situation that it is unconnected with tutor, to construct the system economically, and to make to be easy-to-use. Therefore, in this paper, we develop the 'Intelligent U-Learning System using Cyber Tutor', which includes the conception of u-learning such as mobility, immanency, supports to keep learning without real tutor by cyber tutor, and removes technological and economical costs, verify the validity.

This paper presents a novel method to design and implement mobile u-health system by defining the essential elements of mobile healthcare services. We choose common service elements for the proposed u-healthcare scheme and design the service platform. Especially we focus on automatic feces or urine sensing u-care scheme to prove the effectiveness of our platform. We construct the system with sensing part with a manikin and a diaper, wireless communication part with feces or urine sensing data, and coordinator system based on the u-health platform defined in this paper. Experimental results show that our scheme is useful in the area of u-care service for the handicapped, the elderly, and patients who can hardly move by themselves. In addition the designed scheme offers a realized u-care scheme with the purpose of advanced developing tools for application or service developers.

A time-of-flight and energy (TOF-E) detection system for the measurement of ²³⁶U accelerator mass spectrometry (AMS) has been developed to improve the ²³⁶U/²³⁸U sensitivity at Micro Analysis Laboratory, Tandem accelerator (MALT), The University of Tokyo. With observing TOF distribution of ²³⁵U, ²³⁶U and ²³⁸U, this TOF-E detection system has clearly separated ²³⁶U from the interference of ²³⁵U and ²³⁸U when measuring three kinds of uranium standards. In addition, we have developed a novel method combining kernel-based density estimation method and multi-Gaussian fitting method to estimate the ²³⁶U/²³⁸U sensitivity of the TOF-E detection system. Using this new estimation method, 3.4 × 10^-12 of ²³⁶U/²³⁸U sensitivity and 1.9 ns of time resolution are obtained. ²³⁶U/²³⁸U sensitivity of TOF-E detection system has improved two orders of magnitude better than that of previous gas ionization chamber. Moreover, unknown species other than uranium isotopes were also observed in the measurement of a surface soil sample, which has demonstrated that TOF-E detection system has a higher sensitivity in particle identification. With its high sensibility in mass determination, this TOF-E detection system could also be used in other heavy isotope AMS.

Bei der maschinellen $\"{U}bersetzung(=M\"{U})\;\"{u}bernimmt$ ein Computer die Aufgabe, Texte von einer $nat\"{u}rlichen$ Sprache in eine andere automatisch zu $\"{u}bertragen$. Die meisten $M\"{U}-Systeme$ wurden bis in die 90er Jahre $haupts\"{a}chlich$ von grossen Firmen benutzt, die viele kostenaufwendige $\"{U}bersetzungsarbeiten\;zu\;bew\"{a}ltigen$ hatten. Aber die schnelle Verbreitung des Internets in den Alltag vieler Menschen hat die Situation radikal $ge\"{a}ndert$, und zwar so, $da\ss$ ein $M\"{U}-System$ viel $h\"{a}ufiger$ verwendet wird und es auch bei individuellem Bedarf Anwendung findet. Mit zunehmendem Volumen der zu $\"{u}bersetzenden$ Texte im Internet wird die Nachfrage nach einem $M\"{U}-System\;immer\;gr\"{o}sser$. Ziel der vorliegenden Arbeit ist es, ein Verfahren der maschinellen $\"{U}bersetzung$ der deutschen WWW-Texte ins Koreanische zu beschreiben. Dazu habe ich versucht, zwei unterschiedliche $M\"{U}-Systeme$ zu koppeln. Das Potential dieser Methode ist vor allem deswegen zu untersuchen, weil die sogenannte Lingware fur das Koreanische und Deutsche, wie z.B. Lexikon, Grammatik, Transfer-Lexikon, nur begrenzt zur $Verf\"{u}gung$ steht. Das erste System ist das $M\"{U}-System\;SYSTRAN\;f\"{u}r$ das Sprachpaar Deutsch-Englisch, das die deutschen WWW-Texte ins Englische $\"{u}bersetzt$. Das zweite ist em $M\"{U}-System\;f\"{u}r$ das Sprachpaar Englisch-Deutsch, das die vom Deutschen ins Englische $\"{u}bersetzten$ Texte ins Koreanische $\"{u}bersetzt$. Bei der Evaluierung der $\"{U}bersetzungen$ vom Deutschen ins Koreanische konnten etwa $30\%$ der Ausgaben als korrekt bewertet werden.

This paper is proposed an adaptive fuzzy bilinear synchronization design for uncertain $L\ddot{u}$ chaos system. It is assumed that the $L\ddot{u}$ chaos system has unknown parameters. First, The $L\ddot{u}$ chaos system can be reconstructed via TS fuzzy bilinear modeling. We design an adaptive fuzzy bilinear synchronization control scheme based on TS fuzzy bilinear $L\ddot{u}$ chaos system with uncertain parameters. Lyapunov theory is employed to guarantee the stability of error dynamic system between TS fuzzy bilinear $L\ddot{u}$ chaos system and the proposed slave system and to derive the adaptive laws for estimating unknown parameters. Simulation results is given to demonstrate the validity of our proposed synchronization scheme.

The objective of this research is to get the lesson of the policy by searching the factors of technology acceptance focused on u-Health system. For the purpose of this research, this study presented the concept of u-Health and literature review associated with technology acceptance. Also, this research analyzed the factors affecting 'acceptance of u-Health system'. As a result of the analysis, the first factor affecting acceptance of u-health system is 'self-efficacy' and the second factor is 'connecting'. These results showed characteristics of the innovative aspects and the 'anytime and anywhere' in the ubiquitous concept. Therefore, considering these factors when developing with the priority of u-health system will be able to increase the likelihood of business revenue.
