Thiourea leaching of silver sulfide was studied in weakly acidic sulfate solutions containing ferric sulfate as a moderate oxidant. In the presence of ferric ions, the sulfide sulfur was converted into elemental sulfur and the silver was extracted as its thiourea complex ion, Ag(NH_2CSNH_2)_3^+. In the leaching without oxidant, silver sulfide was leached according to the H_2S forming reaction, where the elimination of H_2S from the leach liquor, for instance by nitrogen gas flow, significantly favored the leaching. In the both cases, the presence of thiourea was necessary for the extraction of silver from the sulfide. The moderate leaching conditions such as fairly low acid concentration at a level around 0.06mol/l and the operation temperature not higher than 50℃, and a high concentration of thiourea promoted the silver extraction mainly due to the increased stability of the thiourea complex ion of silver. It was also observed that silver sulfide was easily extracted in the oxidative thiourea leaching where sulfide ore consisting mainly of pyrite, arsenopyrite, stibnite and chalcopyrite coexisted.

It is very difficult to live far away from one’s own country, in a foreign country with a different language and culture, most advanced nations that accept immigrants encourage them to learn the language used in that country, and run public services offering language and cultural education. In Japan, however, such services rarely by well-intentioned citizen volunteers. The Kawasaki city board of education conducts an activity called “Shikiji class” at the Kawasaki city Fureaikan facility and seven other public pavilions. The purpose of this activity is to enable foreigner residents to meet the Japanese citizens, to accept “the other “ just as they are, to talk about what they wish to, and consider what the society they both live in should be, and to aim toward achieving it. The basic idea is “study together” and “live together.” However, in reality the number of residents who attend the “shikiji class” wanting to improve their Japanese ability for everyday life is hot few. It is clear that additional Japanese educational institutions besides the existing “shikiji class”, where they can learn the Japanese necessary to live in Japan should be made. Such organizations should be set up. By the Japanese government, managed by local governments, with NPOs that esteem the idea of the “Shikiji class” taking charge of the education.

This study used printed questionnaires to survey university students(n=348)to understand the impact of young people's values on their fashion behavior. Its findings showed that when self-reporting their jacket size, about 60% of males reported wearing size L or larger, while about 30% of females reported wearing size L or larger. There were few statistically significant differences by gender on assessed average scores for value items, and the three factors of I. Assertiveness/Self-esteem, II. Need for Approval, and III. Negativity/Fatigue were identified. Statistically significant differences by gender were apparent for many fashion behavior items. Structural equation models having strong fit were identified for both values and fashion behavior. Young persons who were more assertive and had more need for approval in analysis by value type(four clusters)tended to be more assertive in their self-expression through fashion behavior. On the other hand, many of the young people were passive in their values and uninterested in fashion behavior. These findings suggest that young people can develop assertive values by being given opportunities to take an interest in how they dress.

The aim of this paper is to reconsider the relation between narrative and the power of judgment in Kant's sense, among which has been pointed out to be a close relationship. The results of this study are as follows: on one hand, diverse studies on narrative theory have reached agreement on these points: (1)in narrative is found the connection between two different kinds of orders (i. e. the chronological one and the non-chronological one); (2)the formation or reformation of narrative is set off by some contingent elements or the lack of connection between them; (3)narrative enables our self-understanding and gives the foundation of personal identity. On the other hand, the power of judgment in Kant's sense has these characteristics: (1)it mediates between two different kinds of orders (i. e. the one of nature and the one of freedom) in the same field of experience: (2)it subsumes some contingent elements under a new order: (3)it is led by a sort of feeling of pleasure: (4)it has a foundation on our bodily nature: (5)it contains two different viewpoints (i. e. the one of human limited understanding and the one of another kind of understanding). As a conclusion, narrative and the power of judgment have come out to have in fact many similarities. The above points (1) and (2) are obviously, also the other points are in fact thought to be applicable to both these activities.

The Sino-Japanese steamship lines were started by the foreign steamship companies that came to Japan in the last days of Tokugawa regime. The leading character in Jules Verne's 'Le Tour du Monde en Quatre-Vingts Jours', published in 1873, crossed the Pacific between Yokohama and San Francisco on a steamship run by Pacific Mail Steam Company. This company also had a line extending further from Yokohama to Shanghai. The steamship lines between Japan and other countries were monopolized by American and other forign companies before 1875. But in 1875 a Japanese company entered the scene.. The first one was the steamship line between Japan and Shanghai, China as the first overseas line in Japan. Under the instructions of the Japanese Government, M. B. S. S. Co, opened a line from Yokohama to Shanghai via Kobe, Shimonoseki, and Nagasaki on February 3.1875. It was a regular service leaving Yokohama for Shanghai every Wednesday, and Shanghai for Yokohama every Sunday. The line was succeeded by N. Y. S. S. Co. that was newly founded on October 1, 1885. This paper discusses the use of the steamship lines by the Chinese and the Japanese people in the 30 and some years from the opening of the regular line between China and Japan by the Japanese steamship company to the fall of the Qing Dynasty.
