In this paper, we propose a fault tolerant embedded system using memory redundancy on the full-virtualization based virtual machine monitor. The proposed virtual machine monitor first virtualizes main memory of embedded system utilizing efficient shadow page table scheme so that the embedded system runs as a virtual machine on the virtual machine monitor. The virtual machine monitor makes the backup of the embedded system run as another virtual machine by copying memory contents of the embedded system into memory space of backup system according to predefined schedules. When an error occurs in the target virtual machine, the corresponding standby virtual machine takes the role of target virtual machine and continues its operation. Performance evaluation studies show that such backups and switches of virtual machines are performed with minor performance degradation.

When designing a routing protocol in a wireless sensor network, power efficiency and power balance must be considered above all for the life of the network. However, in application services such as environmental monitoring, the urgency and speed of data are more importantly required. In this paper, a routing protocol is proposed to satisfy different requirements for transmission of normal data and emergency data. In the case of general data, it is designed to minimize the power imbalance so that the network life can be extended. In the case of emergency data, the delay is minimized by controlling the power according to the power situation of the node.

To estimatc mutual diffusion coefficient for the analysis of mass transfer phenomena in polymer/solvent system, two models are proposed and the equations are derived. The estimates of mutual diffusion coefficients are obtained by two models suggested in this work and compared with and experimental data and Vrentas-Duda's. Vrentas-Duda's self diffusion coefficient was used for the mutual diffusion coefficient. Derivative of chemical potential on solvent was derived and used using original UNIFAC-FV and modified UNIFAC-FV. However, Vrentas-Duda's equation for mutual diffusion coefficient contains Flory-Huggins parameter x. For the derivative of chemical potential term, Vrentas-Duda assumed that parameter x was constant and independent of temperatures and concentrations The assumption is one of shortcoming in vrentas-Duda's mutual diffusion coefficient. New methods proposed in this work do not have such assumptions and simplifications. For the solvent of cyclohexane, n-pentane, and n-hexane in PIB(polyisolbutylene) and PMS-BR (poly(p-methylstyrene-co-isobutylene), new methods well correlate the experimental data at various temperatures and concentrations, and predicted the experimental data much better than Vrentas-Duda's for the PIB/toluene system. It is shown that new methods are excellent tools for correlating mutual diffusion coefficient data in polymer/solvent system over wide ranges of temperature and concentration without any assumptions or simplifications.

In addition to the Young's modulus, the Poisson's ratio is also at the center of attention in the field stochastic finite element analysis since the parameters play an important role in determining structural behavior. Accordingly, the sole effect of this parameter on the response variability is of importance from the perspective of estimation of uncertain response. To this end, a formulation to determine the response variability in laminate composite plates due to the spatial randomness of Poisson's ratio is suggested. The independent contributions of random Poisson's ratiocan be captured in terms of sub-matrices which include the effect of the random parameter in the same order, which can be attained by using the Taylor's series expansion about the mean of the parameter. In order to validate the adequacy of the proposed formulation, several example analyses are performed, and then the results are compared with Monte Carlo simulation (MCS). A good agreement between the suggested scheme and MCS is observed showing the adequacy of the scheme.

There are several methods for malware analyses. However, it is difficult to detect malware exactly with existing detection methods. Especially, malware with strong anti-debugging facilities can detect analyzer and disturb their analyses. Furthermore, it takes too much time to analyze malware. In order to resolve these problems of current analyzers, more improved analysis scheme is required. This paper suggests a dynamic binary instrumentation which supports the instruction analysis and the memory access tracing. Additionally, by supporting the API call tracing with the DLL loading analysis, our system establishes the foundation for analyzing various executable codes. Based on Xen, full-virtualization environment is built using Intel's VT technology. Windows XP can be used as a guest. We analyze representative malware using several functions of our system, and show the accuracy and efficiency enhancements in binary analyses capability of our system.

Objectives : In ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), the meanings of monarch-fire(君火) and ministerial-fire(相火) described in papers published nowadays are not the same. Therefore, it is necessary to rebuild a clear concept. Methods : To understand the relationships among 'heaven(天)'-'human(人)' and 'name(名)'-'position(位)', the core concept of the ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), I examined the relationships between 'heaven(天)' and 'human(人)' in Neo-Confucianism(性理學) of Song(宋) Dynasty and reviewed the notes of Wang Bing(王冰) which were quoted by Zhu Dan-Xi(朱丹溪) to set the concept of monarch-fire(君火) and ministerial-fire(相火). I studied relevant texts. Results : In ministerial-fire theory(相火論) of Zhu Dan-Xi(朱丹溪), monarch-fire(君火) is perceived as being from greed(人欲) that can cause hyperactivity(妄動) of ministerial-fire(相火), whereas ministerial-fire(相火) is perceived as being able to control monarch-fire(君火) by following the orders from heaven. This point of view is different from the past which recognized monarch-fire (君火) as the owner and ministerial-fire(相火) as the servant. Conclusions : Zhu Dan-Xi(朱丹溪) received the ideological impact of Neo-Confucianism, and accepted the notes of Wang Bing, recognized monarch-fire(君火) as 'name(名)' and ministerial-fire(相火) as 'position(位)', so he voiced the ministerial-fire theory(相火論) that perceived monarch-fire(君火) as fire(火) of the five processes(五行) of human body that came from greed, ministerial-fire(相火) as being in a position to hear the order from the 'heaven(天)' to control monarch-fire(君火). But the concept of ministerial-fire(相火) which he set connoted a confusing meaning of 'nature(性)' and 'way(道)' of Neo-Confucianism. In the later process to solve the problem, life-gate theory(命門學說) was raised, and many researchers had tried to remove the meaning of hyperactivity from the ministerial-fire(相火).

The concept of Myeongmun(命門) could be found in early medical texts such as "Naegyeong (內經)" and "Nan-gyeong(難經)", but the real idea about Myeongmun(命門) had mainly originated from "Nan-gyeong", in successive medical research. The concept of Myeongmun in "Nan-gyeong" could be read as an organ without form, and under the influence of Taoism theory, the concept of Myeongmun could also be understood as Danjeon(丹田). The theory about Danjeon in Taoism theory affected the concept of Myeongmun in medical theory to be closely related with the concept of Hwa(火), especially Sanghwa(相火). Through the theoretical development of Myeongmun and Sanghwa, the concept of Sanghwa could have been understood as a kind of Hwa(火) in human body, and the theoretical development like this had appeared from the time of Geumwon(金元) dynasty, when many medical doctors had experienced the Naedan(內丹) theory of Taoism. Under the influence of Taoism theory, from the time of the Geumwon dynasty to Myeong(明) dynasty, efforts to explain the concept of Myeongmun and Sanghwa in the human body made various meaningful theoretical products, which was not well-known within medical theories of ancient times. We need to recognize the differences in the understanding of the concept of Myeongmun and Sanghwa among each medical doctors, especially among those that showed opposite views. This study is based on the opinion that the difference in the understanding of the concept of Myeongmun and Sang-hwa among each medical doctors had been mainly due to the difference of understanding and analyzing the Taoism theory as the origin of the Myeongmun and Sanghwa theory in medicine. Regarding this, this study will take an overview of the successive development of Myeongmun and Sang-hwa theory in medicine, and will also look into the concept of Danjeon and Sanghwa in Taoism theory, which will allow better understanding of the progress of development of the Myeongmun and Sanghwa theory.
