脳卒中片麻痺患者の立位姿勢制御における周辺視野の影響

脳卒中片麻痺患者(以下、Stroke患者)を対象として、視野内への平行棒提示の有無によって重心動揺および重心移動域が変化するかを実験的に検討した。回復期病棟へ入院中のStroke患者7名を対象とした。重心動揺計を用いて、頭頚部屈曲位で下方を注視する条件(下方条件)、下方条件と同一肢位で視野内に平行棒を提示する条件、の2条件における総軌跡長、実効値面積、前後左右への重心移動面積(安定域面積)を計測し、比較した。静的時の重心動揺の指標である総軌跡長および実効値面積については2条件間に有意差は認めなかった(両指標ともp>0.05)。動的な重心動揺の指標である安定域面積は、下方条件と比較して平行棒条件で有意な増大がみられた(p=0.016)。下方を向いた条件下での視覚参照枠は、静止時の重心動揺には影響を与えず、能動的な重心移動を改善させることが示された。Stroke patients often claimed the fear of falling when upright standing in the large space without support rather than in the narrow space with supporting objects,even they did not touch the objects as a support. We investigated the effects of the parallel bars as a cognitive support. Seven stroke patients who admitted to the hospital were participated. The length of total center of pressure(LNG),the root mean square of sway area(RMS area) and the voluntary maximum sway area(Max area) were measured under the following 2 conditions: eyes fixed downward(downward condition), eyes fixed downward with the parallel bars presented in the peripheral visual field(bar condition). The results showed that the no difference had observed between conditions in the LNG and RMS area (p>0.05). The bar condition increased the Max area when compared with downward condition(p=0.016). Our results showed that the peripherally visual objects(cognitive support) improved the voluntary movement of center of pressure, and we speculated that the motion parallax contributed to the mechanism of this result

Protein induced by vitamin K absence orantagonist II (PIVKA-II)は肝細胞癌(HCC)の腫瘍マーカーとして有名であり,この診断有用性は確認されている。腫瘍マーカーの血清濃度は腫瘍サイズの増加とともに一般に増加し,病態に応じてHCCのほとんどは血清PIVKA-IIの増加と関係している。資料は,HCCと診断された患者の腫瘍サイズと血清PIVKA-IIの測定値の時系列データである。治療時間間隔すなわち病態安定期における腫瘍の発育と腫瘍マーカーの増加に対し,飽和状態を持つ運動方程式の変動としてのモデルの解析を試みた。指数方程式とロジスティック方程式は,内因性腫瘍の発育とその反応曲線の時間的変動を記述する最も一般的な生長カイネティクスモデルであり,血清PIVKA-IIのデータ或いは腫瘍サイズのデータの時系列的プロットに指数方程式の時系列変動とロジスティック方程式の時系列変動をプロットし,その適合度を判定した。結果は,肝細胞癌の増殖システムの仮定のもとで記述されたモデルが定性的に成り立つ時間範囲において,モデルの有用性が示唆された。Protein induced by vitamin K absence or antagonist II (PIVKA-II) is well known as tumor marker of hepatocelluar carcinoma (HCC), and its diagnostic usefulness has been confirmed. Serum levels of tumor markers generally increase along with the increase of tumor size, and most HCCs at some stages are associated with the increase of PIVKA-II in the serum. A document is time series data of measured value of tumor size and serum PIVKA-II level of the patient that HCC was found. The various attempted to model tumor growth and tumor marker increase during the treatment time interval as well as during its unperturbed state have been variations of density-limited kinetic equations. The exponential and logistic equations were popular models currently being employed to describe growth kinetics giving the time behavior of intrinsic tumor growth and its dose-response curve. All that had to be done was the plotting of the fitted exponential or logistic on the plot containing the time and serum PIVKA-II level data or tumor size data. The results emphasized the remarkable predictive ability of the model during an extended period of time in which the modest assumptions of the models were at least approximately true

高校吹奏楽部所属学生における身体症状と身体機能に関する研究

高校吹奏楽部所属学生を対象に、演奏楽器別に整形外科的症状の出現時期や出現部位について明確にすること、ならびに身体機能評価から整形外科的症状との関係について言及することを目的とした. 方法として身体症状はアンケート調査、身体機能評価は協力できる部員に筋力や関節柔軟性を測定した. 整形外科的症状が出現していた部員の多くはユーフォニウム、チューバ担当であり、比較的、大型の重量楽器を演奏する部員に多かった. また、サックス、パーカッション、カラーガード担当も複数の関節に症状が出現していた. 関節の柔軟性については低下している部員が多く、長座体前屈距離や下肢伸展挙上で全国平均値を下回っていた. また、体幹筋力を評価する上体起こしや背筋力は全国平均値を下回っていた.We intended that the students belonging to the brass band in high school to clarify for site of origin and time of appearance of symptoms orthopedic by musical instruments, to mention the relationship between symptoms and orthopedic from the assessment body functions and. Physical symptoms questionnaire, physical function evaluation was to measure the strength and joint flexibility to staff as a way to cooperate. Euphonium, many of the staff orthopedic symptoms had appeared tuba is in charge, there were many in the staff that a relatively large weight to playing an instrument. In addition, the symptoms have appeared in multiple joints sax, percussion, and color guard personnel. For many staff the joint flexibility is declining, was below the national average in distance and elevation on sit-and-reach distance and straight leg raising. In addition, the trunk body to evaluate back strength and sit up was below the national average

チリ・ピノチェット体制確立に至る過程の政治・経済学的考察 : 1970年代から80年代半ばまでを中心として

This article on Chilean Pinochet regime is the result of discussions between two experts of Latin-American Studies, Mr. Watari Takeuchi and Mr. Motohiko Nakagawa, both of them have stayed in Chile in the final period of Pinochet regime in 1980\u27s. This work is composed of two theses, one is the Mr. Nakagawa\u27s political approach and the other is Mr. Takeuchi\u27s economic approach. Mr. Nakagawa analyses, from political point of view, the period after the coup d\u27etat in 1973 up to the mid 80\u27s, that president Pinochet had tried to gain its legitimacy through under taking the "institutional tramsformation project", which is often called "Capitalistic Revolution". The effort at seeking legitimacy was brought into as the 1980\u27s Constitution, which was the ideological, political, economic and social expression of the Pinochet regime. Mr. Takeuchi analyses economic policies under Pinochet\u27s early regime until mid-80\u27s, and makes conclusion that those economic policies were ideological product of "Chicago Boys" (Chilean economist group who had studied at University of Chicago) and they purposed to re-capitalize the Chilean economy and society
