Environmental damage and deforestation occur frequently during ore mining to supply the resource of materials used for nuclear power generation and chemical plants. Further, the air pollution by CO2, SOx, and NOx generated in the production of those materials, affects on the global environment. In order to achieve the sustainable society that does not have a significant impact on the global environment, we have already proposed the material risk indexes which show the materials evaluation at the time of the apparatus design. The indexes consist of three kinds of risks, i. e. the sustainable supply of resources, environmental load during production of material, and toxicity of materials, and the numerical values related to the parameters of these risks were also shown.
　In this research, the construction of the database to store the information about three risk indexes was tried after the determination of data structure of the indexes. The relation between the risk indexes and the properties in the heat-resistant materials provided in the Web information was investigated As a result, based on the optimal environmental conformity, it was clarified that the materials selection for the apparatus using at high temperature should be directed toward the use of materials consisted mainly of easily obtainable atomic elements. The validity of the direction was estimated for various stainless steels and it is indicated that the stainless steel replaced Ni with Mn has a good value in the environmental conformity.

　The aim of this paper is to investigate the structure of the parallel format novel in terms of vocabulary configurations and changes as a story progresses. We target Haruki MURAKAMI's "1Q84" conducting a factor analysis and a rate-of-change analysis to measure lexical frequencies for the chapters associated respectively with the two protagonists of Aomame and Tengo. The factor analysis indicates that features from BOOK2 appear within the parallel strand of BOOK3, which suggests that BOOK3 was written in order to complete the unfulfilled story of the protagonists' reunion. The rate-of-change analysis indicates that the two characters appear symmetrically as a story progresses. The study demonstrates how the conducted analyses, in comparison to literary criticism, are beneficial for narrative comprehension.

　The purpose of this research is to build a basis for scientific analysis of critiques, by utilizing quantitative analysis for objects of critiques. Critiques about movie and theater, which are total work of arts, were selected as target, and nouns which related to objects of criticisms were extracted. Extracted words were categorized in 30 categories, and through chi-square test, evaluated elements of movie and theater were analyzed. Though there are concentrated descriptions about some individual in movie, there are characteristics of distributed descriptions in theater. Also in order to reveal relationships of those categories, those categories were analyzed using factor analysis. As a result, the differences of nuances about "director" and "acting" in movie and theater were extracted. At last, n-gram analysis is applied to extract serial patterns of categories. N-gram analysis revealed that core elements of critique logic were "story" in case of movie, but those elements were "acting" in case of theater.

　Open-source software (OSS) is presently widely used. However, OSS is difficult for novices to use because few OSS products have good manuals. To solve this problem, we have proposed a method of automatically generating a web manual for installing the OSS. However, many OSS products require changes to be made to the configuration file. Furthermore, more systems are adopting OSS as middleware, such as application servers and database management systems. The processing performance of such OSS middleware is known to be low for default settings and a great improvement is achieved by optimizing the system settings. Therefore, this research proposes the automatic generation of a web-based configuration manual employing system optimizing technology.

　The link resolvers provide links between articles published in electronic journals and bibliographic databases. We report on analysis of the log files of a link resolver, bibliographic databases and electronic journals. We have found that the link resolver can lead users from bibliographic databases to electronic journals in a wide range of research fields. In addition, we found that the resolver would lead users more often to journals of specialized subjects than to those of wide subject coverarge like PNAS, Science and Nature. This effect is remarkable in use of generic database like Web of Science.The former are usually accessed to e-journals websites whereas the latter are more frequently accessed more than before as a result of references from the link resolver.

　This study proposes a pattern matching algorithm for math expressions, focusing on their two-dimensional locational structures. The "two-dimensional locational structure" in this paper represents the structure in which symbols such as fractions and exponents are not lined up horizontally. We regard that the math structure is expressed with a nesting structure of strings in our algorithm. In this study, math expressions described by MathML (Presentation Markup) are dealt with. Presentation Markup allows us to describe math expressions with the same appearance in multiple ways. This causes pragmatic insufficiency of the retrieving function if it only treats the descriptive format recommended by MathML specification. By normalizing MathML data, the proposed algorithm is realized with high robustness.
