  • Japan has several unique traditional colors. The traditional colors of Japan include a collection of colors used in traditional Japanese literature, textiles such as the kimono, and other Japanese arts. Japanese color system has a long history, leading to some consistencies in color and naming. During the Edo period(1603~1867), the unique color sense of 'iki' produced many color names that are often related to mouse(nezumi) and tea(cha), and fashion color originated as kabuki actors. As for colors named after animals, the most popular appears to be the mouse, which is used to express grey tones. Recently, many fashion companies in Japan have been working on reviving an interest in traditional Japanese colors. Ordinary people of Edo named even slightly different color tones, each with individual exquisite and mind valuing 'iki' senses. They translated these into their livelihood and culture. The colorimetry result of 49 restored dyed fabrics were as follows; Hue difference was 7.8, value difference was 2.9, chroma difference was 1.8 of prefix siro. Hue difference was 3.8, value difference was 1.6, chroma difference was 1.7 of prefix usu. Hue difference was 3.5, value difference was 1.5, chroma difference was 1.4 of prefix cha. Hue difference was 6.4, value difference was 1.1, chroma difference was 1.6 of prefix koi. Hue difference was 7.5, value difference was 0.8, chroma difference was 3.3 of prefix nezumi.

  • Comparative blook analysis was carried out to investigate the difference of blood constituent in four types of physical constitution. Isoleucine(Ile), Alanine(Ala), Cysteine(Cys), Tyrosine(Tyr), Methionine(Met) were measured. And the following results were obtained: 1. The value of Isoleucine(Ile) on the constitution didn't shown significant difference, but between the value of SO-YANG-IN and SO-EUM-IN showed significant difference. 2. The value of Alanine(Ala) on the constitution didn't shown significant difference. 3. The value of Cysteine(Cys) on the constitution didn't shown significant difference, but between the value of SO-YANG-IN and SO-EUM-IN showed significant difference. 4.

  • This research target students who are majoring in sports at junior colleges and it purpose lies in analyzing the differences in the perspectives towards sports related occupations following the individual characteristics of the students. First, when it comes to the difference of the interest in an organization, sophomore shows more difference than freshman and students who are more than 23 years old shows more difference than students who are 21 or 22 years old. Second, when it comes to the difference in economic incomes, sophomore shows more difference than freshman and students who are more than 23 years old shows more difference than students who are 19 or 20 years old. Third, when it comes to the difference in societal status, sophomore shows more difference than freshman. Fourth, when it comes to the difference in the sense of pride towards one's occupation, male students shows more difference than female students, freshman shows more difference than sophomore and students who are more than 23 years old shows more difference than students who are 21 or 22 years old and 19 or 20 years old. Fifth, when it comes to the difference in preference, male students shows more difference than female students. Sixth, when it comes to the rise of social position, there is no difference in sex, school year or age.

  • Temperature difference energy is a good energy source replacing the fossil fuels. In the study, we classified the temperature difference energy as 4 types by the source & using method. For the understanding economic property of temperature difference energy, we tried simle economic analysis. As the result, Pay back period of 4 case of the temperature difference energy are from 1.23 to 12.65 years. Major factors influenced economic effect are operation time and energy user distance from the temperature difference energy source. If we can select optimal capacity and look for more effient energy users, Temperature difference energy play a important role of replacing fossil energy. So, for dess emination of temperature difference energy, we suggest that temperature difference energy must be included in renewable energy. Applying the effective methods among various promotion program of renewable energy policy, utilization of temperature difference energy could be activated.

  • In this paper, we consider the growth and existence of solutions of differential-difference equations of certain types. We also consider the differential-difference analogues of Br$\ddot{u}$ck conjecture and give a short proof on a theorem given by Li, Yang and Yi [18]. Our additional purpose is to explore the similarity or difference on some problems in differential, difference and differential-difference fields.

  • In this paper, we investigate a certain type of q-difference Riccati equation in the complex plane. We prove that q-difference Riccati equation possesses a one parameter family of meromorphic solutions if it has three distinct meromorphic solutions. Furthermore, we find that all meromorphic solutions of q-difference Riccati equation and corresponding second order linear q-difference equation can be expressed by q-gamma function if this q-difference Riccati equation admits two distinct rational solutions and $q{\in}{\mathbb{C}}$ such that 0 < ${\mid}q{\mid}$ < 1. The growth and value distribution of differences of meromorphic solutions of q-difference Riccati equation are also treated.

  • We consider some statistical properties of the first order difference-based error variance estimator in nonparametric regression models with a single outlier. So far under an outlier(s) such difference-based estimators has been rarely discussed. We propose the first order difference-based estimator using the leave-one-out method to detect a single outlier and simulate the outlier detection in a nonparametric regression model with the single outlier. Moreover, the outlier detection works well. The results are promising even in nonparametric regression models with many outliers using some difference based estimators.

  • There are many methods for measuring the difference between two location parameters. In this paper, statistics are proposed in order to estimate the difference of two location parameters. The statistics are designed not using the means, variances, signs and ranks, but with the cumulative distribution functions. Hence these are measured as the differences in the area between two univariate cumulative distribution functions. It is found that the difference in the area between two empirical cumulative distribution functions is the difference of two sample means, and its integral is also the difference of two population means.

  • It is known that the dierence in the length between two location parameters of two random variables is equivalent to the difference in the area between two cumulative distribution functions. In this paper, we suggest two applications by using the difference of distribution functions. The first is that the difference of expectations of a certain function of two continuous random variables such as the differences of two kth moments and two moment generating functions could be defined by using the difference between two univariate distribution functions. The other is that the difference in the volume between two empirical bivariate distribution functions is derived. If their covariance is estimated to be zero, the difference in the volume between two empirical bivariate distribution functions could be defined as the difference in two certain areas.
