The 29 June 2001 rainstorm (total 238 mm; maximum hourly rainfall 98 mm) triggered more than 700 landslides and associated lahars at Aso Volcano, central Kyushu, SW Japan. Most of the landslides were concentrated in a 20-km^2 area that includes the northeastern slope of post-caldera central cones, the northern slope of Nekodake Volcano and the eastern caldera wall. We mapped landslides triggered by the storm using field observations and 1 : 20,000-scale aerial photography provided by the Kumamoto District Forest Office taken in December 2001. Most of the triggered landslides were shallow (about 1 m thick) soil slips in unconsolidated airfall tephra layers overlying lava flows and pyroclastic rocks. Average volume of the landslides was 550 m^3, but some had volumes exceeding 10,000 m^3. The rupture surfaces of most landslides were formed near the boundary between upper blackish and lower brownish tephra layers. These layers have differences in permeability, grain size and soil hardness. Most landslides mobilized completely into lahars, traveling a few kilometers along stream channels. Although some lahars eroded channel side slopes and transported boulders (2-3 m in diameter), most contained up to about 80 percent silt-to-clay-size particles, similar in composition to the original landslide debris. Sediment discharge volumes by the tephra-slip-induced lahars were estimated at an order of 10^3-10^4 m^3/km^2 using sediment volumes trapped by check dams. These volumes are similar or one-order of magnitude smaller than the volumes of the 1953 and 1990 landslide disasters in the same region. The characteristics of landslides and lahars and their estimated volumes provide important information about landslide and lahar hazards at Aso Volcano.

In this study, the nuclear expression of nuclear factor kappa B (NF-κB) in 48 tissues specimens from 25 canine spontaneous mammary gland tumor (MGT) patients was assessed by immunohistochemistry to compare their levels with clinical features, histological types, prognostic outcomes and proliferative activities, including the mitotic index (MI) and cylcinD1 expression. Twelve of eighteen (66.7%) malignant tumor tissues showed greater than 10% nuclear staining, while benign tumor and hyperplastic tissues showed less than 10% nuclear staining. Higher nuclear expression of NF-κB was positively correlated with larger tumor size, lymph node metastasis and higher MI; however, no correlation was observed with distant metastasis and cyclin D1 expression. Higher NF-κB nuclear expression correlated with shorter patient survival. These findings suggest that NF-κB is a useful prognostic factor for canine MGT patients.

尿路結石の再発予防に対して適切な飲料物を,市販の缶またはペットボトル飲料の成分分析により考察した.また尿路結石の既往がない正常男子6名を対象にビール350ml×3缶飲酒前後の24時間尿の尿生化学検査を行い,ビールの尿路結石形成への影響を検討した.麦茶,ミネラルウォーター,オレンジジュース,ワインは尿路結石形成・再発予防に対して適切な成分を含有していた.ビール飲酒により尿量は有意に増加し,尿浸透圧と尿中クエン酸排泄量は有意に低下したが,尿中尿酸排泄量の有意な増加は認めなかった.ビールに比べプリン体カット発泡酒は容認できる飲料物と考えられるが,尿中クエン酸排泄量低下のリスクがあり,食事同様バランスを考慮した摂取が必要であるThe incidence of upper urinary stones has been increasing since World War II in Japan. One of the causes is the change in dietary habit to a more westernized diet. The consumption of animal protein, fats and oils also correlates with the incidence of upper urinary stones. The results of numerous treatments for preventing formation of calcium stones are not sufficient, and the improvement of daily life habits and dietary advice have been proposed to be important. An increased intake of fluid is of great value for patients with stone diseases, irrespective of the stone composition. We discuss whether or not non-alcoholic and alcoholic beverages, are appropriate for prevention of stone diseases from the viewpoint of the contents of the beverages.

Effects of freshmen's motivation and achievement in campus life on their self-esteem were investigated, and results were discussed from the perspective of their career education. Questionnaires were distributed among freshmen (n = 259) on three occasions: at the beginning of the first semester (April), at the beginning of the second semester (September), and at the end of the second semester (January). Results indicated the following. (1) Attributes such as the process of entering the university and whether the university was the first preference affected self-esteem even in January. (2) Making many friends and developing deep relationships with them in the first semester positively affected self-esteem in January, whereas achieving the same in the second semester did not affect self-esteem.

本稿では、Twitterに発信するメッセージのような短い文の入力をターゲットとした新たな作文手法「完成文変更方式」を提案する。既存の文章入力システムでは、全ての文字をタイプするなどにより文を先頭から入力し、文末まで入力が完了したところで文が完成するが、我々の提案する手法は自動的に生成された文をベースに変更を加えていくという方式で、常に発信可能な完成した文があるという状態を保つことにより、その時点で掛けられる手数によらず発信文を生成することができる。その実装へ向けた第一段の試作として、位置情報に基づき自動的に複数の候補文を生成してユーザに提示し、発信のできるシステムGhostTweetを試作した。We propose a new text input paradigm for short messages, named Composition by Altering Complete Sentense. A system with a method under this paradigm provides a complete sentense. A user can alter a part of the provided sentense or request another sentence to make it suitable to his/her intention. Unlike traditional text input methods, with which a sentense is imcomplete until a user type or select the last word, the system always shows a complete sentense as a candidate according to user's input. This means our method is available even for a user who is only able to share little resource for input. We implemented a prototype application, named GhostTweet, to investigate the paradigm. GhostTweet shows some automatically generated candidate sentense to tweet, according to location information.

特集 : 社会学 社会心理学 文化人類学投稿論文In recent years, news access in multiple formats on multiple platforms emerged. By taking diary records of graduate students' news exposure in this media environment, this study investigated (1) the pattern of using platforms to acquire news and (2) content preference on news exposure. Results indicated that young generation uses internet (PC) more than TV to acquire news. News diary of the participants showed that they acquire news on various platforms, such as web portal, an online newspaper, RSS, mixi news, and Twitter/Facebook. Some patterns of platforms' usage are recorded. It is suggested that the pattern of news diffusion could change because SNS such as mixi, Twitter and Facebook is the main news source for many cases.The results showed that most youth were exposed only to soft news except for the news about the earthquake. Meanwhile, only a small number of participants acquired hard news such as business or political news. Most hard news readers used RSS.

This paper analytically investigates the validity of Eaton and Lipsey's (1976) conjecture that there exist more than one equilibrium configurations in an infinite two-dimensional market. The competition considered here is under the assumptions of (i) an infinite two-dimensional market, (ii) fixed and identical mill price for all firms, (iii) evenly spreading consumers endowed with inelastic demand functions, (iv) firm's zero conjectural variation. etc.It is scrutinized whether or not several configurations of the firms in a two-dimensional market are in Nash equilibrium, and among which regular hexagonal configuration and regular square configuration are proved to be in equilibrium.Comparison between equilibrium configurations of one-dimensional and two-dimensional markets shows that they are qualitatively different in terms of “strength of equilibrium” and “social optimality”.
