Microsatellite markers were developed for the endangered orchid Calanthe izu-insularis (Orchidaceae). This species is unique to the Izu Islands in Japan. Unfortunately, its population size has decreased because of excessive collection for horticultural purposes. In addition, although natural hybridization between C. izu-insularis and C. discolor var. discolor has been reported, morphological differences between C. izu-insularis and the hybridized individuals remain unclear. Using next-generation sequencing, 11 polymorphic microsatellite markers were developed. All developed markers could amplify C. aristulifera and nine markers could amplify C. d. var. discolor, two other orchid species that are also endangered in Japan. The number of alleles and expected heterozygosity at each locus were 1–6 (mean, 2.35) and 0.00–0.79 (mean, 0.30), respectively. These microsatellite markers will help conservation geneticists in their investigation of the proportion of pure C. izu-insularis individuals in the Izu Islands.

Insufficient sleep is a common occurrence in occupational settings (e.g. doctors, drivers, soldiers). The resulting sleep debt can lead to daytime sleepiness, fatigue, mood disorder, and cognitive deficits as well as altered vascular, immune and inflammatory responses. Short daytime naps have been shown to be effective at counteracting negative outcomes related to sleep debt with positive effects on daytime sleepiness and performance after a normal or restricted night of sleep in laboratory settings. However, the environmental settings in the workplace and the emotional state of workers are generally not conducive to beneficial effects. Here, we tested whether relaxation techniques (RT) involving hypnosis might increase total sleep time (TST) and/or deepen sleep. In this study, eleven volunteers (aged 37-52) took six early-afternoon naps (30 minutes) in their occupational workplace, under two different conditions: control ‘Naps' or ‘Naps + RT' with a within-subjects design. Our results demonstrate that adding RT to naps changes sleep architecture, with a significant increase in the TST, mostly due to N2 sleep stage (and N3, to a lesser extent). Therefore, the deepening of short naps with RT involving hypnosis might be a successful non-pharmacological way to extend sleep duration and to deepen sleep in occupational settings.

Post Keynesian endogenous money supply theory appeared as one of the modern theory of credit money some twenty years ago. In recent years, while it keeping close relationship with French and Italian monetary circuit theory, the domain of the theory has expanded gradually. With regard to the role of government or state, the theory of endogenous money pays attention to the central bank which offers the means of settlement between commercial banks and plays the role of lender of last resort, but actually the state establishes money, and practices the control of money. In this respect Chartalism or state theory of money revive in the context of Post Keynesian in recent years. The relationship between the theory of endogenous money and Chartalism comes into question, because in the theory of endogenous money money supply is endogenous, while in Chartalism at a first glance exogenous money supply by the state is assumed. The two theories have not only a background of Post Keynesian, but also both theories have complementarities. That is, the theory of endogenous money deals the money of private level, and Chartalism argues the money of state level. However, both theories share nominalism especially in the theory of nature of money. In Chartalism the nature of money is regarded as establishment of money by the state, and Chartalistic money is a nominal one which has basically no relation to the real value, in the theory of endogenous money bank money also does not presuppose the relation to the real value of money. In this way, both theories share common ground, but there are differences. First, in the theory of nature of money the definition of money and various points are different. Second, both theories diverge in the role of the state. In the theory of endogenous money although the role of the state is generally assumed in relation to the function of central bank, the relationship between money and state, and the problem of Chartalism is not thoroughly examined. The placement of the state in Chartalism is unique and different from the theory of endogenous money. In this paper, aiming at clarifying what relationship both theories have, two points are examined. First, we compare both theories in the theory of nature of money, and we consider in what significance money in the real world is Chartalistic. Second, we investigate the role of the state, especially the function of the central bank respectively. The conclusions are three-fold. First, the theory of endogenous money and Chartalism share nominalism in the theory of nature of money. Nominalism is important in that it is a basis of the view against commodity theory of money. Second, two theories are different except nominalism of money in the theory of nature of money. In the theory of endogenous money the state plays important role in that it designate money as means of final settlement, this is the significance of Chartalism in the theory of endogenous money. Third, the role of the state in the theory of endogenous money moreover emerges as a function of central bank. The function of lender of last resort which is emphasized especially in Post Keynesian theory plays important role which maintains monetary and financial system, while in Chartalism central bank plays the role of bank of government, and does not conflict with central bank in the theory of endogenous money, but it has complementary function. Particularly both theories adopt the operation of short term interest rate as a measure of policy, which plays important role in the control of money.

lepton-quarkの統一模型として,相対論的なdeformable rotator modelが検討される。結果としてlepton-quarkに対するWeinberg-Salam型の理論に実体的な解釈が与えられると同時に,いくつかの特徴的な結論が導かれる。i)lepton-quarkの固有スピンと弱アイソ・スピンとはrotatorの回転モードに起因する相互に不可分の量で,ともにSU_2構造をもつ。ii)rotatorの"変形主軸"の回転モードから,フレーバー自由度として新たにSU_2&otimes;SU_2構造,従ってそれに伴う2種のフレーバー・アイソ・スピンL^^→,M^^→が現われる。iii)"変形主軸"方向のdilatation自由度から,カラーSU_3とleptonとquarkを識別するU_1構造が導かれる。iv)この拡がり模型の斉合的記述には一般化されたKaluza-Klein型の多次元空間の導入が必要とされ,後者の計量テンソルγ_<AB>(A,B=1,2,・・・,4+n)を通じて4次元重力テンソル場g_<μν>(X),上述のlepton-quarkの内部対称性を局所化するためのYang-Mills場A^a_μ(X)(a=1,2,・・・,n),および対称性の自発的破れを誘発するHiggs場と見做されるスカラー場g_<ab>(X)(a,b=1,2,・・・,n)が自動的に理論内部に導入される。v)この理論からの予見として,(ν_τ,τ),(t,b)につづくlepton-quarkの第4のsequential doubletの存在とともに,さらに複雑な構造をもつlepton-quarkの励記状態の存在の可能性が指摘される。

The effect of moxibustion on warts has been known since ancient times and some modern medicalbooks contain descriptions of such treatment. The cure mechanism of moxibustion on warts is still unknown. But it is assumed that, in moxibustion treatment, the burned products of moxa which penetrate the warts are the acting agents.Now I report two clinical cases. One case showed that moxibustion treatment and the application of burned moxa products on warts together were effective against the warts. The other showed that moxibustion treatment alone was able to cure the wart with black mole.

The neurokinin 1 receptor (NK1R) plays an important role in the pathogenesis of acute pancreatitis (AP). Maropitant is an NK1R antagonist that is widely used as an antiemetic in dogs and cats. In the present study, we investigated the anti-inflammatory action of maropitant in a mouse model of AP. AP was induced in BALB/c mice by intraperitoneal administration of cerulein, and maropitant was administered subcutaneously at a dose of 8 mg/kg. We assessed the mRNA expression levels of NK1R and substance P (SP) in the pancreatic tissue via real-time reverse transcription polymerase chain reaction. In addition, the effect of maropitant on plasma amylase, lipase, and interleukin-6 (IL-6) levels was measured in each mouse. Inflammatory cell infiltration in the pancreas was assessed by myeloperoxidase (MPO) staining. Our results showed that AP induction significantly elevated the mRNA expression of SP in the pancreatic tissue. Treatment with maropitant significantly lowered plasma amylase and IL-6 levels. In addition, treatment with maropitant inhibited the infiltration of MPO-positive cells in the pancreas. The present study suggests that maropitant possesses an anti-inflammatory activity, in addition to its antiemetic action.

Recent studies have shown that dietary content affects the health of the host by changing the gut microbiota. However, little is known about the association of microbiota composition with habitual diet in Japanese people. Here, we aimed to clarify the relationship between the fecal microbiota and habitual dietary intake of micronutrients, macronutrients and food groups in healthy young Japanese women. Analysis of fecal microbiota was performed by the terminal restriction fragment length polymorphism (T-RFLP) method, and a dietary survey was conducted over three consecutive days using a weighed food record method. T-RFLP pattern analysis divided the subjects into two clusters, where cluster A group had a high relative abundance of Bacteroides and Clostridium cluster IV, and cluster B group had a high relative abundance of Bifidobacterium and Lactobacillales. Cluster A group also had lower intakes of iron and vitamin K and higher intakes of mushrooms and snacks than cluster B group. Analysis of Spearman rank correlations found several significant relationships between fecal microbiota and intake of nutrients and food groups. Bifidobacterium was correlated with iron intake, and Clostridium cluster XI was negatively correlated with intakes of cholesterol and eggs. These results suggest that dietary habits may strongly affect Bifidobacterium, Bacteroides and Clostridium abundance in the gut microbiota of young Japanese women. This is the first study to show relationships between fecal microbiota and habitual dietary intake in Japanese people. Accumulation of results from similar studies will help to elucidate the relationships between dietary intake and diseases in Japanese people.

本研究では,カスタマーセンタや,遠隔授業などの遠隔コミュニケーションにおいて,対話相手との同調的な感情表出を支援するビデオチャットシステムを提案する.他者の表情を模倣する「ミラーリング」は,他者と友好な関係を築くうえで有効である.しかし,継続的な感情の表出と抑制には本人の意識的な努力を必要とする場合があり,感情労働による消耗を助長させる恐れがある.他方,遠隔コミュニケーションにおいては,ビデオチャットのような情報メディアを介する段階でコミュニケーションに関する要素に情報的変調を加え,感情表出を補助することで対話者間の共感を深めて,コミュニケーションを拡張することができると考えた.本研究では,表情認識センサによって取得した自身の表情と同調するように,対話相手の表情を画像処理によって変化させることで,疑似的なミラーリングを発生させる.提案システムを用いた評価実験として,表情変形が施される模倣者と,自身の表情と同調した表情変形を観測する被模倣者のペアで会話してもらった.その結果,模倣者と被模倣者の両者に対して,会話の円滑さや,共感度の指標が向上することが示唆された.疑似的なミラーリングの効果が,被模倣者だけでなく,模倣者に対しても影響していることが分かった.

This paper examines the representation of Blacks in contemporary Japanese literature and the mass media. It argues that many stereotypes Japanese hold concerning Blacks are in part the product of an uncritical acceptance of Western representations of Blacks and in part a result of power relations which have influenced the type of images of Blacks Japan receives from the West, particularly the United States, and which serve to perpetuate racial stereotyping.

一般の人々に大学の公開オンライン講座を提供するMOOC (Massive Open Online Course) が急速に拡大している.MOOCは講義動画を中心とした学習コンテンツで構成され,受講者は掲示板上で他の受講者と交流できるが,なかには講師による直接の指導や他の受講者との対面学習を希望する受講者もいる.本研究では,日本史がテーマの一般向けMOOCで,講師の指導のもと他の受講者と議論を通した対面学習を希望する受講者に対し,MOOCコンテンツを事前学習に位置づけ,グループ演習中心の対面学習と連動させた反転学習の実践データから反転学習の効果を評価した.具体的には,修了合否と知識の活用力としての歴史的思考力に対する反転学習の効果を,受講者属性やオンライン学習行動による効果も踏まえ,それぞれの効果の大きさを比較して検証した.その結果,修了合否に対しては反転学習の有意な効果は確認されず,動画視聴と掲示板活動の効果がより大きく,高齢者や非大卒の受講者に修了率がやや低い傾向が示唆された.一方,歴史的思考力に対しては本講座の修了者を対象に反転学習のより大きな効果が示され,動画視聴と掲示板活動の効果は小さく,年齢や学歴の効果も限定的であった.
