<p>国内外を問わず誤情報の拡散が社会的な問題となっており,情報の真偽検証の必要性が急増している. そこで本研究では情報の真偽検証を効率的に行うための支援システムの構築を行った. 本システムではニュース記事に対して言及しているSNS上の投稿をもとに人手の検証を必要とするニュース記事を推定する. 作成したシステムを用いることで検証を必要とする記事の探索作業の効率化を期待できることが確かめられた.</p>

患者は55歳男性.肉眼的血尿,右腰痛を契機に発見された右腎癌でリンパ節・骨・肺転移を認めた(cT1bN1M1).経腹膜的右腎摘除術を施行した.病理組織診断でCD10,P504S,CK19陽性でありTubulocystic carcinoma(pT3a)と診断した.転移巣に対する治療でSunitinibを投与し,CTで腫瘍縮小(部分奏功;PR)を認めた.術後12カ月現在増悪なく治療継続中である.Tubulocystic carcinomaはlow-grade collecting duct carcinomaとAminらが紹介したものに相当し,2004年のWorld Health Organization(WHO)分類に含まれていないまれな腫瘍である.組織学的には,腫瘍細胞は立方体から扁平の形状で嚢胞を取り囲んでおり,大きな核小体と好酸性か両染性の細胞質を有し,軽度の細胞異型があり,その中にHobnail型細胞も認められる.免疫組織学的には,Tubulocystic carcinomaは近位尿細管マーカー(CD10,P504S)と遠位尿細管マーカー/集合管マーカー(Parvalbumin,CK19)の両方に染色されるのが特徴である.この腫瘍は増殖性に乏しい病理組織所見を呈するが,転移・浸潤しやすい性質を持つとされる.転移に対する治療法は確立されていないが,本症例ではSunitinibが有効であった.<br>

The density of invasive alien mongooses on Amami-oshima Island has recently been controlled to a low level by trapping. Aiming for eradication, three dogs were specially trained to detect the location of the animals to improve the efficiency of trapping. The detection efficiency of the dogs was higher than the efficiency of sensor cameras and pipe-type kill traps in each area, which had different mongoose densities. It was also significantly higher in high density areas (p<0.05) and higher than those methods plus hair traps in lower density areas. Dogs could also contribute to capture by handlers. The capture rates of the dog handlers were lower than those of the pipe traps in higher densities areas. However, a mongoose was caught by a dog handler in an area where none had been caught in the past five years. It was revealed that detection dogs are a sensitive means that have the potential for capture by the handler. While it takes a few years to train a detection dog. The area that one pair of a detection dog and a handler could scan thoroughly in a year was estimated at 16-28 km^2. The utilization of detection dogs preferentially in extremely low density areas is considered to be efficient.

<p>Creep behavior of the epoxy resin anchor for CFRP sheet embedded in concrete was studied. Creep tests in 20°C and 40°C with the sustained loads of 3.0kN and 4.5kN were conducted for 42 days (1000 hours), where 3.0kN corresponded to the design load for the anchor. As a result, it was found that the creep displacement in the 40°C test was very large at the beginning of loading compared to the 20°C test. The glass transition temperature, Tg, was assumed to be the reason for the large creep displacement in the 40°C test. Therefore, Tg, tensile strength, and tensile modulus of elasticity were measured with various curing conditions for the epoxy resin. The measured Tg was 41°C with 23°C-7days curing and it increased up to 57°C for 7 days in case the curing temperature was increased from 23°C to 40°C. In addition, it was found that the tensile strength and the tensile modulus of elasticity showed linear relationship with Tg in the range of 41°C to 57°C, and the tensile modulus of elasticity in 40°C was 40% of that in 20°C when Tg was 45°C. The curing condition for 45°C of Tg was equivalent to the beginning of the 40°C creep test. Thus, it was concluded that the reason for the large displacement in the 40°C creep test was because Tg was relatively close to the test temperature.</p>
