Correlation between aerobic threshold and cardiopulmonary response to exercise onset in patients with myocardial infarction

Purpose: This study aimed to identify the correlation between aerobic threshold (AT) and cardiopulmonary response at the start of exercise in patients with myocardial infarction (MI). Subjects and Methods: Thirty-one male patients with MI underwent a sub-maximal cardiopulmonary exercise test with expiratory gas analysis to determine their peak oxygen uptake (V̇O₂) level, using Ramp protocol. Results: The patients demonstrated an extended time constant (TC) and decline in AT in this study. Extended TC suggested impaired cardiac function due to reduced left ventricular ejection fraction (LVEF), as well as an LVEF of 59.8% on average. However, there was no significant correlation between TC and AT. Pearson product-moment correlation coefficients were 0.56 between AT and area under the oxygen uptake curve (V̇O₂AUC), -0.22 between TC and V̇O₂AUC, and -0.23 between AT and TC. Conclusion: V̇O₂AUC is representative of oxygen utilization and is correlated with AT in patients with MI.首都大学東京学位論文 乙第192号 副論

普通科高校から養護学校へ転勤した教師のライフヒストリー研究 : ベテラン教師の教職アイデンティティのゆらぎと再構築

教師の成長とは､長い職業生活を通して教職キャリアを積み上げ､その体験を経験化し、再構築し新たな体験を幾度も繰り返し、教職アイデンティティを形成し、その後退職を迎える過程である。本研究では、ライフサイクル、ライフヒストリーの研究方法について先行研究を整理し、次に具体的事例研究として、1964年に大阪府立普通科高校へ教師として着任し､2002年に養護学校校長で退職した男性教師がどのように教職キャリアを形成し､ベテラン期に入り養護学校へ転勤し､教職アイデンティティのゆらぎと再構築をどのように図り、教師生活を終えたのかを自身の語りを通し、ライフヒストリーの方法で探究し、課題を明らかにする。Ａ teacher is ａ process of accumulating teacher career through long working life, experiencing the experience, rebuilding, repeating new experience many times, forming teaching job identity, and then retiring. In this research, we organized prior research on life cycle, research method of life history, then as ａ concrete case study, in 1964 he took office as ａ teacher to the Ｄ Fiscal High School and retired as ａ school principal in 2002 Fluctuation and reconstruction of teacher identity through teaching how teachers formed teaching career and transferred to nursing school in the veteran period and explored by way of life history how to finish teacher life, to clarify the problem
