Using vegetable origin materials, the synthesis of a new polysilane modified alkyd resin was carried out to produce functional biodegradable polymer materials. Polysilane was added during the transesterification step or the condensation polymerization step. We observed that the rheological properties of the resulting alkyd resins were markedly changed.

Paper money was born as a substitute for metal money in distant commercial transactions. With its denominations eventually becoming fixed numbers, it developed into a currency used by a large number of unspecified people. As the circulation of paper money increased, counterfeiters began to try their hands at producing more. Anti-counterfeiting measures became an important factor in paper money production. Anti-counterfeiting technologies have been improved dramatically over the years: today, color- and pattern-shifting elements are used to make counterfeiting harder and counterfeited money easier to spot in a new technological environment.

Since the Law for the Protection of Cultural Properties was established in 1950, our country has been producing a record of intangible cultural properties, which are characterized as non-physical objects to be protected, as well as tangible cultural properties. The details of the movement of intangible cultural properties could not be recorded because papers were mainly used for recording. Videotapes or DVDs have recently become popular, thus enabling the recording of intangible cultural properties. The method of recording the on-stage performances of professionals in national theaters is applied to the recording of intangible cultural properties. However, as for the intangible cultural properties succeeded by local festivals, discussions on how they should be preserved have just begun, and there are as yet only a few places to store and exhibit them.

Artifact-metrics is an automated method of utilizing artifacts based on their measurable intrinsic characteristics such as microscopic random-patterns and the like which are inherently emerging in their manufacturing process. This method is a kind of sibling technology with Biometrics. This article describes an introductory overview of artifact-metrics with a list of examples including classical paper-based ones as well as a brand-new instance based on nano-photonics. An intrinsic characteristic is called an artifact-metric element. If an artifact-metric element has enough (1) individuality, (2) stability in capturing, (3) durability, and (4) clone-resistance then it can be applied to artifact-metric systems designed for (a) authentication and for (b) reproducing exact values. The former application is well studied and there are many actually used optical systems for plain or micro-magnetic-fiber-embedded paper. The latter application belongs to a relatively new field called physically unclonable functions, which is studied extensively in the context of semiconductor electronic circuits for cryptography.

Principles of the present color systems are briefly described and their limitations are discussed. Since one of the most significant limitation is that color appearance cannot be represented by these color systems, factors influencing color appearance are mentioned and variations of color apearance by these factors are described in order to show how and in what degree colors change. Modes of color appearance has been recently considered as an important factor caused by a higher level of the visual system. Therefore, its effects on color appearance is shown using the results obtained in an categorical color-naming experiment.

This article reviews some recent studies that give the scientific basis for appropriate use of colors in our living environment. Since color is the most effective dimension for visual searching or labeling, we can easily find and recognize items that are specified by colors. The effectiveness of color information, however, is affected by its surrounding environment. First, the illuminance level significantly changes color appearances. Second, surrounding colors strongly affect the efficiency of color searching. Moreover recent studies of quantitative analysis of human sensibilities for color environment are described. A tentative method of estimating visual busyness using color statistics of actual scenes is discussed.

This paper explains how the evaluation of letter contents and the personality of the senders vary according to presentation media and document styles of letters. We conducted a two-way factorial design experiment. The first factor was presentation media: paper and electronic media. The second factor was document styles: mails with a Gothic font, postcards written in a Mincho font, postcards written in a handwriting-like font, and handwritten postcards. It was observed that presentation media strongly affect the evaluation of the personality of the senders. Sending paper letters improves the feeling of familiarity between recipients and senders. Next, the document styles strongly affect evaluation of the contents of letters. Handwritten letters improves the evaluation of letter contents. Finally, the feeling of appreciation is highly evaluated in handwritten letters on paper. Based on the result, we discuss how to select presentation media and document styles depending on situations.

The Bank Card with the magnetic stripe which was started to use in a full scale since 1970 has remarkably been increased in number because the card was recognized as the best suited media for the computer systems in terms of its reliability in transactions, security and high operation speed. As the network systems enlarged and the number of applications increased, however, the number of misused cards and of insolvents has also been increased. Since the IC Card has emerged as the next generation media with the excellent security, the technological perspective for the future use should be seeked both on the multi-purpose application and the security sides.

The motion of the sheet of paper which falls down freely, is analyzed by the method of dynamics. In the previous work, we discussed the motion of the sheet of paper which goes inside the delivery unit of printing machine and rotates around a cylinder. In those cases, no outer force was considered except the force pulling the edge of a sheet of paper. In this work, we considered the outer forces, gravity force and fluid force. Generally, the analysis of the flow around the object is very complicated, and the fluid force affecting the object is difficult to solve. So, we analyzed the fluid force by considering the flow momentum. In this work, we analyzed the case of a sheet of free falling paper. In the future work, we are going to adopt the method discussed in this work to the sheet of paper which goes inside the printing machine.

In addition to bank notes, National Printing Bureau has produced a wide range of security printed products since its establishment in 1871. We have built the original design style based on a combination of Japanese traditional customs and many western techniques. The current design of bank notes reflects the modernization after the Meiji Restoration. The design of bank notes must be reliable and secure. Further, the dignity and respect of the country must be upheld. In addition, the most important property of security printed products is their ability to gain social trust. In order to gain social trust, security printing employs various anti-counterfeiting measures. Design identities describing the history and technical sophistication are also necessary to further enhance credibility. Design identities are the key to achieving security printed products with higher credibility.

"Kirishitan's (Christian's) books" were printed by the printing machine that Jesuit Order of Priest brought in Japan. Some of the books were also published in Japanese. There were skillful Japanese artisans who joined the printing "Gozan (five mountains) books" for Zen's precept published by the temples of Buddhism in Kyoto area. They had a good works and important role to press the "Kirishitan's (Christian's) books". However, they pulled out of the work in 1594 because they had to print "Kobunkeikyo" books summarized old Chinese ethics and moral. The publication of "Kobunkeikyo" was ordered by the Emperor. It is supposed that students in Seminaryo that was a school established by Jesuit Order of Priest in Japan took over the printing of the "Kirishitan's (Christian's) books" from the artisans, and started the work in 1594
