We extracted the communities located in the coastal area and clarified the characteristics of them using the 2015 Agriculture and Forestry Census data and the results of the national census, taking Ehime Prefecture as an example. We categorized them used the employment rate data by industry and analyzed the agricultural area types of the communities included in each type. As a result, of the total 3,284 communities, 628 (19%) were coastal communities, and 23% (340,000) of the population lived there. In addition, from the viewpoint of agricultural area type, it was found that the ratio of hilly agricultural areas is high and agricultural land is often used as upland in coastal communities. As a result of cluster analysis using the ratio of employees by occupation as a variable, coastal communities were classified into 6 clusters. As a result, it was found that in the coastal area, mountainous agricultural communities are areas where fishing industry is thriving, and flatland agricultural communities are mostly citrus-cultivated areas using slopes. The high proportion of hilly agricultural communities is due to the development of relatively large orchards and the narrowness of the forests found on the islands and peninsulas. As a result, the number of communities not included in the mountainous agricultural area increases due to the increase in the cultivated land ratio or the decrease in the forest field ratio. Furthermore, it was found that many communities specializing in primary industry are in areas with high geographical isolation, and that the number of workers per community is small in these communities.

Formation of oxygen vacancy-rich conducting filament in the metal-oxide insulating layer due to applied electric field is studied using phase field modelling. We consider that the formation of the Frenkel defects plays a dominant role in the process of filament formation. The choice of any other type of defects have been neglected due to the consideration of charge neutrality. We find that during the initial stages of filament formation, intrinsic defect concentration plays a crucial role. However, during the late stages, when the filament formation approaches completion, because of the increased electric field, the generation of new Frenkel defects dominates the growth mechanism. Our observation confirms that the intrinsic defects are not sufficient for the completion of conducting filament in the insulating memresistive layer. Our numerical analysis helps us to better understand the formation mechanism of conducting filament and to determine the key material parameters that influence the operation of oxide based non-volatile random access memory (RAM) i.e. resistive RAM (ReRAM).

近年,周辺の土地への竹林の拡大が日本各地で問題となっている。竹林の適切な管理計画立案のためには,その成立を規定する地形条件の解明が必要である。先行研究において,比較的限定された地域における地形条件の解明がなされてきた一方で,広域で竹林の成立可能な気候条件(潜在生育域)下を対象とし,地形条件を解明した事例はない。本研究は長野県を対象とし,竹林の位置情報を航空写真および現地踏査によって把握し,潜在生育域と竹林の成立する土地の地形条件を県全域で比較した。その結果,竹林の潜在生育域は斜面傾斜度0°付近と30°付近に二つのピークを持ち,全方位に一様に分布するのに対し,竹林(10,523カ所,総面積1,449.0 ha)は斜面傾斜度5~20°の緩傾斜地に55.7%が,南東,南,南西向き斜面に53.5%が成立していた。この竹林の地形条件の傾向は,県内5地域(北信地域,中信地域,東信地域,南信地域,木曽地域)いずれにおいても共通であった。これらの結果から長野県内の竹林は,南向きの緩斜面の条件に多く生育しているという傾向が明らかとなり,土地利用や竹林経営の観点から現在の地形条件に植栽され残存してきたと推察された。

肺癌術後に健側肺のみに出現した急性肺障害のため術後ARDSに陥った症例を経験した.肺癌術後にALIやARDS等の急性肺障害を発症する場合,その多くは術前から肺に線維性変化が認められることが多く,術後急性増悪として理解されている.術後急性増悪によるARDS症例では通常,肺障害は両側性に現れるが,自験例では手術操作を加えていない健側肺にだけ認められた.なぜ手術操作を加えていない健側肺にのみ急性肺障害が生じたのか原因不明である.術中片肺換気におけるdepending lungであるためventilator-induced lung injuryの関与が疑われるが推論の域を出ない.過去に健側肺のみに生じた肺癌術後急性肺障害に焦点をおいた報告はなく,急性肺障害発症のメカニズムを探求する上でも貴重な症例と考え報告する.

Swarm robotics requires a practical scheme to maintain operator supervision for the acceptability of systems' autonomy by humans. For this purpose, this paper proposes a distributed algorithm for continuous connectivity between robots and a base station to maintain the controllability and transparency of the swarm. This algorithm forms network topology among the swarm members and deploys repeaters to maintain the connection to the base station by a role switching scheme. Preliminary simulations have shown that the revised acute angle test reduced the cost of the network formation with the Gabriel graph topology. Through the simulated patrol missions, the proposed algorithm successfully maintained the continuous connectivity between the base station and the swarm members without significant inequality in the computational cost among swarm members. Furthermore, as the number of robots increases, the computational cost per robot does not increase significantly. These results indicate the distributed nature and scalability of the proposed algorithms.

WebサーバがWebブラウザから,端末の特定に繋がる情報(以降,特徴点と呼ぶ)を採取するBrowser Fingerprintingという手法がある. Browser Fingerprintingはユーザの許可を得ずに行うことが可能であるので,対策ツールを用いて特徴点の偽装を行うユーザもいる.しかし,多くの対策ツールで有効性は示されていない.そこで本論文では,Firefox,Chromeそれぞれで特徴点の偽装を行うアドオンを対象に,特徴点がどの程度偽装できるのかを調査した.その結果,特徴点の一部を偽装できるアドオンと,全く偽装ができていないアドオンが明らかになった.

Two patients with anti-centromere antibody (ACA), hypertensive emergency, and acute renal failure, mimicking scleroderma renal crisis, without Raynaud's phenomenon and typical skin manifestations of systemic sclerosis (SSc), are reported. A review of 26 ACA-positive patients between March 2003 and March 2011 in Yokosuka Kyosai Hospital identified four additional patients with similar manifestations. All patients were Japanese women between 41 and 84 years of age at presentation. Human leukocyte antigen (HLA) genotyping tests revealed the absence of the HLA-DQB1*0501 and DRB1*0101 alleles, which are associated with disease susceptibility to ACA-positive SSc among Japanese. These subjects' manifestations may represent a novel entity.

Glucosinolates, a group of sulfur-containing specialized metabolites of the Brassicales, have attracted a lot of interest in nutrition, medicine and agriculture due to their positive health effects and their involvement in plant defense. Their biological activities and the extensive knowledge of their biosynthesis have inspired research into development of crops with enhanced glucosinolate contents as well as their biotechnological production in homologous and heterologous systems. Here, we provide proof-of-concept for transgenic suspension cultures of carrot (Daucus carota, Apiacae) as a scalable production platform for plant specialized metabolites using benzylglucosinolate as a model. Two T-DNAs carrying in total six genes of the benzylglucosinolate biosynthesis pathway from Arabidopsis thaliana as well as NPTII and BAR as selectable markers were transferred to carrot cells by Agrobacterium tumefaciens-mediated transformation. Putative transformants selected based on their kanamycin and BASTA resistances were subjected to HPLC-MS analysis. Of 79 putative transformants, 17 produced benzylglucosinolate. T-DNA-integration was confirmed for the five best producers. Callus from these transformants was used to establish suspension cultures for quantitative analysis. When grown in 60-ml-cultures, the best transformants produced roughly 2.5 nmol (g fw)−1 benzylglucosinolate, together with up to 10 nmol (g fw)−1 desulfobenzylglucosinolate. Only one transformant produced more benzylglucosinolate than desulfobenzylglucosinolate. The concentration of sulfate in the medium was not a major limiting factor. High production seemed to be associated with poor growth and vice versa. Therefore, future research should try to optimize medium and cultivation process and to separate growth and production phase by using an inducible promoter.
