Low-latency projection is a key technology for fast motion-adaptive projection. Digital Micromirror Devices (DMDs) are widely used for this purpose because they enable high frame rate projection of binary patterns, although additional techniques are needed to realize projection of multi-valued images. This paper proposes a low-latency projection method, Binary Frame Warping, with which displayed patterns are warped at the binary pattern rate instead of the video frame rate. Experimental results suggest that the proposed method applied to 60-fps video input offers perceived image quality comparable with that offered by over 500-fps projection.

The purpose of this study was to examine the relationships between running performance and the cross–sectional area of the psoas major, peak oxygen uptake, and running economy in male junior long–distance runners. The subjects were 37 male junior athletes who achieved good records in interscholastic athletic competition during 5 years (2011–2015). Their seasonal best times in a 5,000 m race (5,000m–SB) were 14:04.11 ± 0:07.25 (13:53.64–14:16.15). In a multiple regression analysis, 5,000m–SB was statistical significantly correlated with the cross–sectional area of psoas major (16.0 ± 1.7 cm2) measured on magnetic resonance imaging and peak oxygen uptake (4.25 ± 0.36 l min-1 [76.9 ± 5.8 ml min-1 kg-1]) during a lactate curve test comprising five stages. However, 5,000m–SB was not related to oxygen uptake at the work–load which was less than the load at the lactate threshold estimated by using the lactate curve test results. These results suggest that a high volume of the psoas major, the largest hip–flexor muscle, and peak oxygen uptake are among the important factors for junior long–distance runner performance.

Academica Histrica (ROC) published a series of source books on Chinese repatriation from all over the world after WWII. One of the volumes has sources of Academica Histrica and an explanation on the return of Chinese from Southern Sakhalin after the Soviet–Japanese War. However, the explanation lacks references to other official documents of other archives and media sources. In addition, the author of the explanation failed to weigh the information in official documents from the view of Karafuto/Sakhalin history. This paper clarified the following points on Chinese in Karafuto/ Southern Sakhalin using official documents of Academica Histrica, Archive of Institute of Modern History, Academia Sinica (ROC), The Second Historical Archive of China (PRC) and Archive of Shanghai-city (PRC), in addition, newspapers and magazine articles published in China. Chinese in Southern Sakhalin contacted diplomatic establishments of the ROC in the USSR and returned to China in 1947 under the scheme for overseas Chinese repatriation established by the ROC - the same as other Chinese in the USSR. One hundred and sixty-one persons left Sakhalin for Shanghai, ROC as a Chinese returnee group and at least 4 Chinese remained in Sakhalin. It is estimated that the returnee group consisted of around 120 Chinese and around 40 Japanese families. Anxiety over regime change caused their return. They were not purged under the socialist regime in Sakhalin though they had stood by the Wang Jingwei regime under the Japanese Empire. However, socialization of the economic system and an increase of Soviet citizens damaged their lives because most of them had been engaged in commerce. The government of Shanghai-city shouldered the most important role for supporting these returnees from Southern Sakhalin. The Shanghai branch of the Ministry of Foreign Affairs, ROC made every effort to accommodate them just after their arrival; however, the branch and the central government did not have a budget to support them. Not only these returnees from Southern Sakhalin but also returnees from other areas of the USSR and domestic refugees generated by the Chinese Civil War had flowed into Shanghai. Discharge of these populations was an urgent issue for Shanghai-city. Shanghai-city planned to settle these returnees and refugees on uncultivated lands in Zhejiang and Jiangxi provinces as relief works. However, it emerged that those lands were not suitable for agriculture and the returnees from Southern Sakhalin had no intention to move to those lands though some of them came from those provinces. One-third of the returnees from Southern Sakhalin had desired to move from Shanghai to Taiwan just after the return and that rate rose to three-fourths in a month, though there was no one among them from Taiwan. Some of the domestic refugees also desired to move from Shanghai to Taiwan. The Chinese Civil War had already proceeded and these refugees regarded Taiwan as one of the safe areas in China. The reasons specific to returnees from Southern Sakhalin desiring to move to Taiwan were the linguistic barrier in Shanghai, linguistic advantage in Taiwan and reunion of family in Japan. Shanghai and the surrounding areas had a variety of Chinese dialects and there were few people among the returnees from these areas. As an official document stated, it was very difficult for them to get a job there. On the contrary, many people came from Fujian province and spoke Fujian dialects, which was one of major dialects in Taiwan; moreover, it is natural that they expected that they could communicate in Japanese there because Taiwan was a colony of the Japanese Empire the same as Karafuto. In addition, an example of reunion of family in Japan via Taiwan has been known. The colonial government of Karafuto launched the evacuation during the Soviet-Japanese War and many women, children and senior citizens moved to Hokkaido. The Soviet army sealed off La Perouse Strait and many families were separated. The return of Chinese from Southern Sakhalin was a kind of unwilling displacement of citizens of the victorious nations generated by a series of border shifts after WWII, such as the return of the USSR citizens from China to the USSR. For their fatherlands, the victory of the war meant the liberation or the restoration of independence; however, for them, whether victory or defeat, border shifts derived from the war meant the disorganization of the order which they had help build as foreigners.

本稿では,階層型コウホート(HAPC)モデルによる推定でコウホート効果がフラットになるメカニズムを明らかにし,ベイズ型コウホート(BAPC)モデルで用いられているパラメータの1次階差に着目することが妥当であることを述べる.HAPCモデルは近年のコウホート分析において標準的手法であり,一般的に時点とコウホートを個々の対象者が属する集団の効果として,それらを変量効果として扱う混合効果モデルである.しかしながら,HAPCモデルによる推定はコウホート効果が想定よりもフラットになりやすいとの批判もなされてきた.他方,BAPCモデルはパラメータの1次階差に正規分布を仮定した経験ベイズ流の枠組みで従来とらえられてきたが,混合効果モデルとしてとらえることも可能である.両者とも変量効果の導入で識別不足を解消する点は共通だが,コウホート分析における識別問題へのアプローチは異なる.実証例として,コウホート効果が大きいと考えられる男性大学卒割合を用いて,両モデルの推定結果の違いを示す.HAPCモデルの推定はコウホート効果がフラットであるのに対し,BAPCモデルはコウホート効果が大きく,新しい世代ほど大学卒割合が高くなるという特徴を捉えていた.

This article is a preliminary report on the international expedition to theTuvans in China, Russia, and Mongolia that was conducted in the summer of2012 as a Cultural Resource Project of the National Museum of Ethnology(Minpaku). The author investigates features of the way of life and cultureof the Tuvans living in these countries and clarifies the similarities anddifferences arising from their different social circumstances. The majorityof Tuvans live in Russia, where they have a recognized position and territory—the Tuva Republic. In the territories of China and Mongolia, Tuvansare national minorities and do not have national-territorial status. HoweverTuvans of all three countries still keep their native language, ethnic consciousnessand traditional culture. This article focuses on elements rangingfrom “historical baggage” to the language and cultural situation of this community,to relations with the host societies, and to the interaction betweenthese factors.

目的:費用対効果評価制度における分析は,『医療経済評価研究における分析手法に関するガイドライン』(経済評価GL)に基づいて実施することとなっている.経済評価GLにおいては,診療報酬改定の影響を補正するために,診療行為レベルでの単価の補正を推奨しているが,他の補正方法との比較検討はなされていない.本研究の目的は,レセプトデータを用いた医療費分析において診療報酬改定の補正方法について検討することである.方法:本研究では2009年 4 月から2016年12月のおよそ 8 年間における医科およびDPCのレセプトデータから,1度でも入院をしたことのある者の解析用IDを抽出し,当該解析用IDの中から無作為に25%分を抽出したナショナルデータベース(NDB)を使用した.2012年度から2016年度にかけて,DPCコードおよびDPCコード内における患者定義が同一のDPCコードにおける入院症例を解析対象に定めた.診療報酬改定の補正方法として以下の 4 方法を定めた:1DPC包括部分・診療行為・薬価・材料に対して2016年度単価を使用,2薬価・材料のみに対して2016年度単価を使用し,その他は診療報酬本体改定率を使用,3診療報酬本体・薬価・材料に対して全体的にネット改定率を使用,4補正を行わない.本研究では,経済評価GLが推奨する 1 を用いた補正方法によって算出した医療費に対して,2~4のそれぞれを用いた補正方法によって算出した医療費の比率を算出し,補正方法の違いによる医療費推計結果の違いを比較検討した.結果:「2012-2013年度」,「2014-2015年度」,「2016年度」の間で,DPCコードおよび患者定義が変更されていないDPC数は,2016年度全DPCコード数:4,918件のうち,999件(20.3%)であった.一方,「2014-2015年度」,「2016年度」の間では1,528件(31.1%)であった.経済評価GLが推奨する補正方法 1 による医療費に対して,各補正方法で算出した医療費の比は,補正方法 2 では1.01,補正方法 3 では0.99,補正方法 4 では1.00であった.ただし,DPCコードによって医療費比が±10%程度の相違が生じ,一部のDPCコードでは±20%以上の誤差も生じていたが,どの補正方法においても相違の傾向は同様であった.結論:経済評価GLにおいて推奨されている補正方法 1 は,DPCコード内容の変更の影響が大きいことから現実的に実施困難であることが明らかになった.また,より簡便な補正方法2~補正方法 3 を用いた場合でも,推計結果に大きさ誤差を認めなかった.そのため,結果の精度と分析実施可能性に鑑みてネット改定率(補正方法3)を用いることが許容される.
