| Abstract | Clinical effects of spa therapy were examined in 60 elderly asthmatics in comparison between ex-smokers with a long history of cigarette smoking more than 20 years and never-smokers. Spa therapy wse effective in 47 of the 60 subjects (78.4%) with asthma. Ragarding in influence of cigarette smoking, the therapy was effective in 16 of the 24 astmatics (66.7%) with a long history of cigarette smoking. In con-trast, the therapy was effective in 31 of the 36 asthmatics (86.1%) withput smoking history. The spa efficacy was significantly larger in asthmatics without smoking history than those with (P<0.05). There was no significant correlation between spa efficacy and IgE-mediated reactions. Bronchial hyperresponsiveness was significantly higher in subjects with slight or no efficacy of spa therapy than in those with marked and mod-erate efficacy both in ex-smokers and never-smokers as well as in total subjects. The generation of leukotriene B4 (LTB4) by leucocytes was significantly increased in sub-jects with slight or no efficacy of spa therapy than in those with marked and moderate efficacy in total subjects and in those with smoking history, but not in those without smoking history. The generation of leukotriene C4 (LTC4) by leucocytes was not sig-nificantly correlated with spa efficacy in total subjects, and also either in ex-smokers or never-smokers. The results demonstrate that clinical effects of spa therapy are in-fluenced by long-term cigarette smoking, which increases bronchial hyperrespon-siveness and the generation of LTB4 by leucocytes. |

| Abstract | Costs of drugs used for the treatment for 1 year were examined in 32 pa-tients with asthma in relation to disease severity. Asthma severity was classified as : 1) intermiitent; 2) mild persistent; 3) moderate persistent; 4) severe persistent. 1. The total cost of drugs used for each patient for 1 year was the highest (￥263,710) in patients of stage 4 (severe persistent) and the lowest (￥74,670) in those of stage 1 (intermittent). The costs of bronchodilators and antiallergics were predominant at all stages, and their cost increased significantly with increasing severity. 2. The costs of drugs such as antiallergics and bronchodilators were predominant, and the costs of drugs such as inhaled corticosteroids and mucolytics were considerably high in pa-tients of all stages. 3. The costs of bronchodilators, inhaled corticosteroids, and antiallergics were the largest in patients of stage 4. The results suggested that the costs of durgs used for the asthma treatment tended to increase as the disease sever-ity became stronger from stage 1 to stage 4, and the maln drugs related to the in-crease in total costs were bronchodilators, antiallergics, and inhaled corticosteroids. |

| Abstract | Education for Sustainable Development(ESD)-Environmental Education, has been a major concern at most UN summits. The 2002 Johannesburg Summit broadened the vision and re-affirmed the objective of the Millennium evelopment Goals (MDS) and proclaimed the Decade of Education for Sustainable Development for the period 2005-2014. This emphasized that education, is critical for promoting sustainable development and improving capacity of the people to address environment and development issues. This paper seeks to report, a finding on the level of student awareness and interests in environmental issues at a High School in Japan (a Super Science High School). A curricula unit was developed in the area of environmental education on soil. An actual chemistry class has been conducted in English. Pre & post lesson questionnaires were administered to the students. The result of the analysis indicates that, students are aware of environmental issues but need to be exposed to these issues in the form of activity-based classroom lessons. This we believe, will enable the students appreciate the fact that ESD is a life-wide and lifelong endeavor which challenges individuals, institutions and societies to view tomorrow as a day that belongs to all of us. This we presume is the main challenge of the MDS. |

| Abstract | The remarkable development in [CT (Information and Communication Technology) was observed in the past decades that it has an increasing impact on economic and social activities in the wurld. Similarly, [CT have had a significant role in the economic growth for developed and developing countries. Therefore, no region has been more dynamic in recent years than East Asia, which is one of the most important geugraphic regions based un [CT. Addit.iunally, focusing on Gross Domestic Product (GDP) per capita income distributions of East Asian countries in this study, it is also aimed to show that lCT and its components are closely linked with socio"economic components in macro and micro level, especially with GDP per capita components. In this regard, the Neoclassical Growth Model and its Convergence Theory are discusst'd to show the effects of [CT investments and developments as a catalyst factor that would increase the multi regional development achievements. Finally, in the light of analyses, it is observed in this study that there are some evidences for regional convergence as a weak Beta-convergence and a strong Sigma-convergence within homugeneous regions of East Asian countries in terms of GDP per capita income distributions. |

| Abstract | This study investigated what kind of social skills international students staying in Japan learn and use throughout their stay which are significant fur funning relationships with Japanese. Informants were international students who have been staying in Japan for at least two years. Semi-structured interviews were carried out on 12 students from various countries. These interview responses were analyzed by using the KJ method and contenr analysis. The analysis revealed three major categories of specific Japanese skills: politeness, especially toward their proffessors; keeping harmony instead of insisting their opinions all the time; and steps for closeness, which means to take time to be close to others. We also found that they switched behaviors when selecting the appropriate acquired social skill and changed levels of using social skills depending on the context and people with whom they interacted. |

| Abstract | The optical properties of clouds were measured with a polarization Mie lidar during April, 2004 and investigated to categorize the particles detected by the lidar. The cloud layers were categorized into five types according to the depolarization ratios, as follows: (I) constant and small (less than 5%); increasing with height (II) nearly from 0% and (III) from about 50%; (IV) large and varying with the backscattering coefficient; and (V) sharply decreasing. This categorization of clouds enabled us to separate aerosols from clouds in a lidar signal. Comparison of the backscattering coefficients between clouds of types (I) and (II) suggested that the depolarization ratio induced by multiple scattering in dense clouds does not depend on the particle density. Estimation of the particle phase for the five cloud categories was also examined. |

| Abstract | In this paper, we focus on developing a high-speed square root (SQRT) algorithm required for an elliptic curve cryptosystem. Examining Smart algorithm, the previously well-known SQRT algorithm, we can see that there is a lot of computation overlap in Smart algorithm and the quadratic residue (QR) test, which must be implemented prior to a SQRT computation. It makes Smart algorithm inefficient. The essence of our proposition is thus to present a new QR test and an efficient SQRT algorithm to avoid all the overlapping computations. The authors devised a SQRT algorithm for which most of the data required have been computed in the proposed QR test. Not only there is no computation overlap in the proposed algorithm and the proposed QR test, but also in the proposed algorithm over GF(p(2)) (4 | p − 1) some computations can be executed in GF(p); whereas in Smart algorithm over GF(p(2)) all the computations must be executed in GF(p(2)). These yield many reductions in the computational time and complexity. We implemented the two QR tests and the two SQRT algorithms over GF(pm) (m=1, 2) in C++ language with NTL (Number Theory Library) on Pentium4 (2.6GHz), where the size of p is around 160 bits. The computer simulations showed that the proposed QR test and the proposed algorithm over GF(p(m)) were about 2 times faster than the conventional QR test and Smart algorithm over GF(p(m)). |

| Abstract | This paper proposes an algorithm for generating prime order elliptic curves over extension field whose extension degree is a power of 2. The proposed algorithm is based on the fact that the order of the twisted elliptic curve is able to be a prime number when the extension degree for the twist operation is a power of 2. When the definition field is F(2(40)−87)(4) , the proposed algorithm can generate a prime order elliptic curve within 5 seconds on PentiumIII (800MHz) with C language. |

| Abstract | Geometric fitting is one of the most fundamental problems of computer vision. In [8], the author derived a theoretical accuracy bound (KCR lower bound) for geometric fitting in general and proved that maximum likelihood (ML) estimation is statistically optimal. Recently, Chernov and Lesort [3] proved a similar result, using a weaker assumption. In this paper, we compare their formulation with the author’s and describe the background of the problem. We also review recent topics including semiparametric models and discuss remaining issues. |

| Abstract | We present a new method for extracting objects moving independently of the background from a video sequence taken by a moving camera. We first extract and track feature points through the sequence and select the trajectories of background points by exploiting geometric constraints based on the affine camera model. Then, we generate a panoramic image of the background and compare it with the individual frames. We describe our image processing and thresholding techniques. |

| Abstract | Thermal behavior of Coulomb clusters in a three dimensional confining potential is investigated by molecular dynamics simulations for system sizes of 1,000 to 20,288 ions. The specific heat of the system of shell-structured 20,000 ions is peaked almost at the same temperature as the system of bcc-structured 20,288 ions with much sharper structure for the latter. The diffusion coefficient and the peak to valley ratio of the two-dimensional pair distribution function on the outermost shell are obtained both as a function of temperature. The rotational movement of each shell in the system of 104 ions is observed. |

| Abstract | We present a real-space, polynomial-expansion approach to electron dynamics in nanostructured semiconductors. The Chebyshev expansion method is employed for efficient calculation of timeevolution of single-electron wave function. Details of the formulation are described. The method is applied to the electron transport in nanostructured semiconductors such as Si nanowires. The mean-square displacement and diffusivity of electron in Si chains are obtained as functions of length of the chains. The results show clearly ballistic behavior of electron in the pure Si chain. |

| Abstract | In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near the furnace walls. As the result, the whole temperature distribution in a furnace could be obtained from such limited data. Furthermore, to control the temperature distribution in a reactor furnace, gas flow from multiple tuyeres and supplying material for controlling temperature distribution in a reactor furnace were determined by the SQP method. It was shown that temperature distribution in a furnace was regulated to achieve various desired distribution. Thus, it was verified that complicated temperature distribution in a reactor furnace could be controlled by combining furnace simulation and SQP method. |

| Abstract | In this paper, neuro based intelligent diagnosis methods for electro-mechanical control system are proposed. A self organizing map neural network (SOM) is used to classify measured data of the target system as a qualitative diagnostic method. Besides of the above procedure, it is expected to attain more efficient maintenance by a quantitative estimation of failure. For the purpose, new method is proposed using a hierarchical neural network (HNN). In the method, classified results by SOM are processed for the quantitative diagnosis. Hierarchical neural network can identify inner structure of the relations between failure causes and its results that enables a quantitative diagnosis. |
