The purpose of this study was to investigate the differences of the motions between the speed throw and the distance throw, using a three-dimensional(3D) motion analysis. Twenty-four male university baseball players were the subjects of this study. They were asked to throw a ball (mass 0.144kg) horizontally as fast as possible (speed throw: ST), and as far as possible (distance throw: DT). These motions were filmed by two high-speed video cameras. 3D landmark coordinates of the subiects and the ball were calculated by the DLT method. The following kinematic parameters were computed: angle of release, the component velocities of the ball, the 3D angles for the backward/forward lean, right/left lean of the upper torso, and the twist of the torso and those for the abduction/adduction, horizontal flexion/extension, internal/external rotation at the shoulder joint, and the flexion/extension at the elbow joint of the throwing arm. The sequential data were normalized with the time from the stride foot contact to the ball release, and then averaged. Angle of release was significantly larger in the DT than in the ST. Significant difference was not found between the resultant velocity of the ST and the DT. Vertical velocity of the ball was significantly larger in the DT than in the ST during the latter half of the acceleration phase. On the other hand, horizontal velocity of the ball was significantly larger in the ST than in the DT. The backward lean and the left lean angles of the upper torso were also significantly larger in the DT than in the ST throughout the all sequences analyzed. Ranges of these angular displacements between the stride foot contact and the release, however, had no significant difference between the ST and the DT. The shoulder adduction angle was also significantly larger in the DT than in the ST during the latter half of the acceleration phase. These results indicate that the differences in the release parameters between the ST and the DT were caused not only by the throwing arm motions but also by the motions of the upper torso. It has been suggested that the motions to upward and left ward of the upper torso helps to achieve longer throwing distance in the DT, and that forward lean of the upper torso possibly contributes to achieve larger horizontal ball velocity at the release in the ST.

Fra gli intellettuali italiani attivi in un periodo denso di inquietudini come quello degli ultimi decenni del Settecento, spicca la figura di Alessandro Verri (1741-1816). Questi, dopo la breve attivita giornalistico-illuministica nel periodico milanese <<Il Caffe>>, si ritira a vita privata stabilendosi a Roma nel 1767. Il suo nome riappare al pubblico solo quindici anni dopo con il romanzo Le Avventure di Saffo, che conosce un grande successo editoriale grazie allo stile raffinato e al tema carico di pathos. Da un esame della sua impostazione intellettuale, risulta interessante il fatto che il romanziere cercasse di trasmettere una visione pessimistica della passionalita, tema che puo essere individuato anche in altre sue opere. Questa scelta sembra non solo segnare un netto distacco ideologico dalla sua posizione giovanile, ma anche anticipare un tema letterario abbastanza singolare nel contesto culturale dell'epoca: la tragicita delle passioni. Il presente lavoro intende chiarire il processo tramite il quale nel Verri maturo precocemente l'interesse per questo tema, rintracciando i suoi numerosi riferimenti ai sentimenti e alla sensibilita. Contrariamente alla visione pessimistica tipica della fase romana, durante il periodo de <<Il Caffe>> il Verri fu uno dei fautori piu appassionati dell'utilita dei sentimenti, esaltandone i lati positivi allo scopo di attaccare il rigido autoritarismo, soprattutto in campo intellettuale. Il suo "sentimentalismo" non ha un carattere originale, poiche il Verri seguiva la corrente filosofica dell'epoca, ma resta comunque degno di nota il fatto che alcuni dei suoi articoli fossero gia intrisi di una percezione negativa delle passioni umane. Seppure il valore dei sentimenti sia sempre rimasto un fermo criterio di giudizio, il pensiero verriano viene messo alla prova con il viaggio in Europa in compagnia di Cesare Beccaria. Di fronte alle inquietudini del compagno e alle dolorose esperienze relative al contatto con i filosofi francesi, viene concepita via via sempre piu consapevolmente la negativita delle passioni. In tale processo si profila gradualmente la duplicita del suo atteggiamento nei confronti dei sentimenti: esaltazione sul piano teorico e scetticismo su quello pratico. Allo scopo di spiegare lo sviluppo del pensiero verriano, e opportuno prendere in considerazione l'ambiente familiare sotto il cui peso si sentivano oppressi i fratelli Verri: l'avversione all'autorita paterna, infatti, rappresento uno dei motivi piu importanti che li avevano condotti alle attivita illuministiche. Tuttavia, la maturita intellettuale di Pietro contribui fortemente a orientare la presa di posizione del fratello minore, a dispetto della sua intima natura. Numerose espressioni e idee somiglianti negli scritti dei due fratelli attestano la forte influenza ideologica esercitata dal fratello maggiore. Confermata la caratteristica eteronoma del sentimentalismo di Alessandro, sembra naturale che la fede in quel criterio sia venuta meno con il distacco fisico dal maestro e che, nello stesso tempo, ad essa sia subentrata una visione pessimistica peraltro gia latente. Il sentimentalismo verriano attraversa una nuova fase a Roma dove il Verri si innamora della marchesa Margherita Gentili. Inebriato d'amore, decide di non allontanarsi dalla marchesa, compiendo un cambiamento esistenziale dall'impegno civile al conseguimento della felicita individuale. Per giustificare la propria scelta, egli contrappone con insistenza la sublimita dei sentimenti ai suggerimenti razionali di Pietro. La disputa finisce con la vittoria di Alessandro, ma questa non puo che essere effimera e preparatoria al disinganno fatale. L'infedelta della donna amata lo obbliga a ripensare totalmente il proprio giudizio di valore basato sui sentimenti e ad accettarne la falsita. Da un'attenta osservazione delle peripezie verriane intorno al valore dei sentimenti, sembra fondato ritenere che una serie di amare esperienze abbia influenzato fortemente la sua poetica, che trovera poi forma definitiva nei romanzi e nei drammi. Questo processo rappresenta un momento interessante nella genesi di una nuova sensibilita letteraria, emersa dal conflitto fra gli ideali illuministici e l'affermazione dell'io. Per chi scrive, l'originalita dell'approccio verriano non dovrebbe essere semplicisticamente sottovalutata come una manifestazione preromantica, ma approfondita alla luce del contesto culturale del suo tempo.

Ternary content addressable memory (TCAM) is becoming very popular for designing high-throughput forwarding engines on routers. However, TCAM has potential problems in terms of hardware and power costs, which limits its ability to deploy large amounts of capacity in IP routers. In this paper, we propose new hardware architecture for fast forwarding engines, called fast prefix search RAM-based hardware (FPS-RAM). We designed FPS-RAM hardware with the intent of maintaining the same search performance and physical user interface as TCAM because our objective is to replace the TCAM in the market. Our RAM-based hardware architecture is completely different from that of TCAM and has dramatically reduced the costs and power consumption to 62% and 52%, respectively. We implemented FPS-RAM on an FPGA to examine its lookup operation.

傍気管嚢胞(paratracheal air cyst)は,第1~第3胸椎レベルの気管右側に好発する,比較的まれな良性の嚢胞性疾患である.われわれは術前CTで傍気管嚢胞を診断した3例の食道癌手術症例を経験した.いずれの症例も嚢胞が右反回神経周囲リンパ節を郭清する過程で同定され,郭清手技に注意を要した.傍気管嚢胞は術前にその存在を認識していなければ,術中にリンパ節と判別することが難しい形状やサイズであり,認識なく術中に遭遇すれば嚢胞損傷の危険性が高いと考えられた.胸部食道癌手術において左右反回神経周囲リンパ節郭清は重要であり,食道癌の術前評価では傍気管嚢胞も念頭に置くことは重要であると考えられた.

The purpose of this paper is to consider the meaning of changes in the discourse on “Okinawa Problem” before and after the “Return” on the basis of a case study of the National Conference for Educational Research (NCER). This is done in the context of questioning the idea of “postwar”. This research is based on reports from 1966 to 1978 of the NCER by an agency of the Japan Teachers' Union. This paper demonstrates changes in the discourse on “Okinawa Problem” by the “Return”. To study discussions at the NCER chronologically, this paper aims to describe interactions with “Hondo” and Okinawa and to approach to the trait of influence of Power in discourse. I reexamine the “postwar” by giving attention to the voices of Okinawa that was structurally suppressed during the cold war.

食用昆虫は持続可能な食糧資源として推奨されているが,その栄養的および機能学的特徴については十分には解明されていない。食用昆虫は代替タンパク質資源であると考えられる場合が多いが,食用昆虫の中には脂質を多く含むものも存在し,さらに脂質の構造的特徴は昆虫の種や昆虫の飼料および成長段階によって異なると考えられる。加工食品への食用昆虫や昆虫油脂の利用を考えると,食用昆虫原料を質的および量的に評価することが重要である。著者は,食用昆虫を重要な脂質資源であると考え,世界に約2000種類存在する食用昆虫の中でも代表的な食用昆虫であり,国内でも加工粉末が市販されるトノサマバッタ(成虫),カイコ(蛹)および数種類のコオロギ(成虫)の油脂の特徴について検討してきた。本稿では,食用昆虫の油脂の量および質に関する栄養学的な分析知見を示し,著者らの先行研究で得られている食用昆虫の油脂に期待される生理作用について紹介する。食用昆虫油脂の質に関して,我々はトノサマバッタおよびカイコにはn-3系脂質であるα-リノレン酸,コオロギにはn-6系脂質であるリノール酸が結合した中性脂肪およびリン脂質が豊富に含まれることを示した。さらに,リン脂質の中ではホスファチジルコリンが主要なリン脂質種であるが,その他のリン脂質種も含有されていることを示した。昆虫油脂に期待される栄養生理作用について,食用トノサマバッタ粉末をラットに給餌したところ,肝臓における脂質代謝が改善されることを示した。これらの研究より,食用昆虫は機能性に優れる多価不飽和脂肪酸やリン脂質を含む油脂源であることが示唆された。昆虫を食糧油脂源や機能性油脂源として利用することによって,国連が推奨する持続可能な開発目標(SDGs)に対する貢献も大いに期待される。

Acute abdominal pain is one of the most frequent causes of admission to emergency departments. However, there is a shortage of detail information showing the difference of outcomes or etiology of acute abdominal pain according to age. We therefore conducted an epidemiological analysis to reveal the difference between age on outcomes and etiology of acute abdominal pain using an administrative database associated with the Diagnosis Procedure Combination (DPC) system. We obtained discharge data relating to 12,209 patients with acute abdominal pain from 931 DPC participation hospitals between 2009 and 2011 in Japan. We compared length of hospital stay (LOS), in-hospital mortality, and etiology of acute abdominal pain between age categories. Patients were divided into five age groups as follows: < 20 (n = 1,106), 20-39 (n = 3,353), 40-59 (n = 2,925), 60-79 (n = 3,144), and ≥ 80 years (n = 1,681). Longer LOS and higher in-hospital mortality were observed in patients aged ≥ 80 years (p < 0.001). Regarding etiologies of acute abdominal pain, intestinal infection or acute appendicitis were more frequent in patients aged < 20 or 20-39 years, while ileus or cholelithiasis were more frequent in patients aged 60-79 or ≥ 80 years in both male and female patients (p < 0.001). This study demonstrated the significant differences between age with regard to the patient outcomes and etiology of acute abdominal pain. The current findings highlight the importance of improving the quality of medical care for patients with acute abdominal pain.
