  • Presently, the number of known asteroids is more than 710,000. Knowledge of size and albedo is essential in many aspects of asteroid research, such as the chemical composition and mineralogy, the size-frequency distribution of dynamical families, and the relationship between small bodies in the outer solar system or comets. Recently, based on the infrared all-sky survey data obtained by IRAS, AKARI, and WISE, the large asteroid catalogs containing size and albedo data have been constructed. In this paper, we discuss the compositional distribution in the main belt regions based on the compiled data on size, albedo, and separately obtained taxonomic type information.

  • According to Hans Kippenberg, the foundation of an academic study of religions coincided with the beginnings of modernization. Since the second half of the nineteenth century most European countries were involved in a process of rapid social change. The repercussions that this had for daily life were momentous. Instead of working for their traditional needs, people now had to produce goods for a market. Old customs ceded to private contracts and political laws. The superior knowledge of science replaced the inherited worldview. This deep changed severed societies from their ties to the past. Many educated people in Europe believed in an imminent end of all religions. Had not the scientific progress superseded the religious worldview? Historians had to come to terms with that expectation when they directed their attention to historical religions. Friedrich Max Muller introduced a new science, so-called Religionswissenschaft through the study of the ancient Vedic sources. He thought that genuine religion was a taste for, and sense of, the infinite. From his point of view, the Indian sources confirm that nature is more than mechanical laws. Thus his interpretation sought to contradict the materialist ideology of his day. Edward Burnett Tylor described religions as a kind of natural philosophy. His notion of 'soul' functioned to explain natural events. This legacy of the past cannot be missed even in modern society. Only the concept of the soul may preserve human dignity in an age of materialism. Gerardus van der Leeuw, also tried to perform the same function of the cultural critique for the renewal of the religious imagination in modern, rationalized Europe imprisoned in the iron-cage. In this respect, we could think that the interpretations of the history of the History of Religions in the light of the intellectual history are very suggestive for the korean student of religion. It helps them to describe the early history of the study of religion in Korea. For example, Yi Neung Wha(李能和) is regarded as 'a father of korean religious studies, but no one could present a proper answer for the question of why and through which connection of his intellectual milieu he was interested in the religious history and the study of religion. We would discover its signification in his confrontation of the prevailing social thought, such as social evolutionism.

  • We constructed an unbiased asteroid catalog from the mid-infrared part of the All-Sky Survey with the Infrared Camera (IRC) on board AKARI. About 20% of the point source events recorded in the IRC All-Sky Survey observations were not used for the IRC Point Source Catalog in its production process because of a lack of multiple detection by position. Asteroids, which are moving objects on the celestial sphere, are included in these "residual events" We identified asteroids out of the residual events by matching them with the positions of known asteroids. For the identified asteroids, we calculated the size and albedo based on the Standard Thermal Model. Finally we had a new brand of asteroid catalog, which contains 5,120 objects, about twice as many as the IRAS asteroid catalog.
