Michael Slote is a philosopher who bases his work on the ethics of empathic care and considers that the ethics of caring and empathy are also effective in realizing social justice. Slote considers justice in the laws, institutions, and practices of society as the analogy for ethics among individuals. Furthermore, Slote rejects the position that the ethics of care is not compatible with considering justice, and he claims that the ethics of care creates its own concept of justice. This article explores the notion of social justice starting from an individual's empathy. How does empathic social justice build its own notion of justice? I will discuss the plausibility and limitations of Slote's theory of justice based on empathy.

Mushroom culture waste was used for methane fermentation and which waste is regional and unique in Nagano Prefecture. In generally, mushroom culture wastes are poor biodegradable which contains huge number of cellulose and lignin. We used 100mL serum vials as methane fermentation batch reactor and used anaerobic sludge biodegraded for food wastes as inoculum. Methane fermentation was carried out using an untreated sample and a sample with pressure extrusion treatment by an extruder. At this time, a methane yield of 234 ml-CH4/g-VS was obtained from the untreated sample, and a 238 ml-CH4/g-VS was obtained from the pre-treated sample. Significant improvement in methane yield was not observed.

A Foucault pendulum used to explain the earth rotation is a teaching matearials in many applied physics textbooks. Observers of the North and South Poles easily understand the changes of pendulum motion, but those who are between the poles and the equator have difficulty observing its changes. When we explain some of the changes in the situation of the Foucault pendulum, this paper enables us to give on explanation of them by recognizing the fact that land surface exists on the surface of a circular cone. As a result, a lot of students are satisfied with this explanation of Foucault pendulum motion itself in practical education of applied physics.

Due to the development of High accuracy Astrometry, the positional shift of QSO due to gravitational deflection of light will be detectable. We showed that it is feasible to measure the mass of single star by observing the variation of gravitational deflection casused by the orbital motion of the Earth. For a stars within 100pc with an appropriate background source sach as a QSO within 1 arcsecond,their mass can be determined by measuring the deflection shift with the accuracy of 10 micro-arcsec. On the other hand, in the case that relative angular distance between star and QSOs is known by the other observation, the mass of star can be determined by measuring the shift of gravitational deflection of light We show the feasible to measure the mass of single star by VLBI Exploration of Radio Astrometry (VERA) and we show the general probability of the existence of candidate stars and the list of same candidate stars up to now. In the future, almost all stars within 1 arc-second from the QSOs become the candidate stars using a high accurate and a massive scaled data from a satellite such as GAIA. Therefore we propose that QSOs with nearby stars should be monitored for detection of gravitational lens effect for to detect the gravitational lens effect due to stars and MACHOs and the measurement of stellar mass.

多胡事象とは、近傍の星で確認された初めての重力マイクロレンズ現象である。標準的な銀河系構造で、このような現象が起きる確率は非常に小さい。しかし、「質量分布関数の低質量側が、標準モデルより大きい」と考えると、この現象が説明出来る可能性がある。実際、MOAグループによる重力マイクロレンズの探査による、近傍の褐色矮星によるレンズ現象の発見や「浮遊惑星」の発見などから、低質量側の質量分布関数が、標準モデルの2倍程度になる事が判った。これらより、多胡天体の正体は褐色矮星や浮遊惑星であると考えられる。これらは、近い将来、固有運動の測定によって明らかにされるであろう。

In the nature, there are three patterns of fluctuation classified by frequency spectrum. They are white fluctuation, 1/f (pink) fluctuation and brown fluctuation. Between the three, it has been reported that pleasant state of mind is supplied by any 1/f fluctuation. In order to create a natural music automatically, we applied this 1/f fluctuation to musical composition and arrangement, which is one of the brain works. Same experiments have been reported, but in this system we used new algorithm for generating 1/f fluctuation we developed.

There lie two quiescent volcanoes and three canyons in the basin of the Torii River. In time of heavey rainfall, driftwoods and gravels are produced in theese areas. Sometimes they cause hydrospheric disaster. On the other hand, these areas are kept in reratively good condition. So we must pay due regard to natural river ecosystems. A good cooperation between engineers, ecologists, and similar experts paired with the work of good service team is essential to water resources management and maintainance.

This paper is an investigation and interpretation (釈論) of 'Oe no Chisato-shu' (大江千里集) which is an anthology of Waka (和歌=ancient Japanese poems) by Oe himself.In this anthology, as usually called Kudai-waka (句題和歌), each Waka is given one phrase poetic title from Kanshi (漢詩=ancient Chinese poem) selected by Oe. The authors of this paper think that the mutual relations between expressions in both Waka and Kanshi have various patterns. So,the central purpose of our investigation is to concretely explicate the actual condition of all these patterns. And first,this paper treats of Waka No.11~No.13 of 'Oe no Chisato-shu'.

May 21, 2012, solar eclipse was observed in Japan. This time, annular eclipse occurred over a wide range; i.e. the southern part of Kyushu, the southern part of Shikoku, the southern part of the Kinki, the southern part of the Chubu, such as the Kanto. Other regions became a partial solar eclipse. Approximately 83 million people are living in the path of annular phase, we were expected many people to observe the eclipse. Eclipse is a valuable opportunity to increase interest in science. On the other hand, when observing the sun, it runs a strong risk that leads to trouble in the eyes of people due to the strong sunlight. For example, in the case of the eclipse in Germany in 1912, solar eclipse retinopathy patients of 3,500 has occurred. We conducted our activities for many people to observe the eclipse safe. One of them is the spread of safe solar eclipse observation method, another is a research study of the safety of the solar eclipse glasses.In this paper, we report the transmittance measured in the various filters; solar viewing glass on the market, and their substitutes. These are valuable archival material related to solar observation glass for the solar eclipse in the future.

McNaught and Asher (2001) predicted the Leonids Meteor Storm in 2001 due to the 4-rev (1866 yr.) and 9-rev (1699 yr) dust trails of the Leonids. To measure the flux and magnitude distribution of very faint meteors, we performed deep imaging telescopic observations with the cooled CCD camera toward the radiant points of the Leonids. We observed the Leonids meteor storm Nov.18 UT 2001, and succeeded to separate the radiant points due to the 4-rev and 9-rev dust trails (Yanagisawa et al. 2003, Torii et al. 2003) and we also succeeded to detect the faint meteors under 10 magnitudes (Kohama et al. 2003). The flux of faint meteors increases with the population index of 2.4, and the flux was obtained as (4.2±2.1)×10^<-4>km^<-2>s^<-1>(mag≦+12). We have found no apparent cutoff of the flux at brighter than~12 magnitude. The size of meteoroid of 10th magnitude meteor is a several tenth μm. Such small meteoroids are not the meteoroids of 4-rev (1866 yr.) and 9-rev (1699 yr) dust trails, because it is considered that they cannot return around the orbit of dust trail due to the solar radiation pressure. Thus we have to consider the new physical mechanism to create such small meteoroids. To established the property of faint meteor distribution, we also performed the deep imaging telescopic observation at the duration of the Leonids 2002 and 2003. This paper describes the detailed observation circumstances of Leonids 2001, 2002, and 2003 and the preliminary result of faint meteor distribution of Leonids.
