A note on homotopy types of connected components of Map(S^4,BSU(2))

Connected components of \Map(S^4,B\SU(2)) are the classifying spaces of gauge groups of principal \SU(2)-bundles over $S^4$. Tsukuda [Tsu01] has investigated the homotopy types of connected components of \Map(S^4,B\SU(2)). But unfortunately, the proof of Lemma 2.4 in [Tsu01] is not correct for $p=2$. In this paper, we give a complete proof. Moreover, we investigate the further divisibility of $\epsilon_i$ defined in [Tsu01]. In [Tsu], it is shown that divisibility of $\epsilon_i$ have some information about $A_i$-equivalence types of the gauge groups

本研究の目的は、現場の看護師が運営する看護師版心理教育(NPE)と NPE の開発者が運営する成果を、 患者の服薬および病気に関する知識の変化に着目して評価し、心理教育を実践する看護師育成に関する示唆を 得ることであった。介入およびデータ収集方法は、精神科急性期治療病棟に入院中の統合失調症患者を対象とし、NPE 開発者が運営するグループに参加した者(開発者群)と開発者から指導を受けた現場の看護師が運 営するグループに参加した者(看護師群)に分け、それぞれ NPE 実施前後の疾病薬物知識度調査(KIDI)を行うというものであった。分析方法は、各群の KIDI 総合得点と下位尺度の得点について、対応のある t 検定を行った。対象者数は、 開発者群が16名、看護師群が16名、男性18名、女性14名、計32名であり、平均年齢は、40.21歳(SD=13.71) であった。分析の結果、KIDI 総合得点ならびに下位尺度(薬物療法)得点は、両群共に実施前より実施後の 方が有意に高い得点を示した。下位尺度(精神症状)得点は、開発者群のみ実施前より実施後の方が有意に高 い得点を示した。NPE は、その運営者が開発者であっても看護師であっても、服薬および病気に関する知識 の総合得点において同程度の成果が期待できるものであったが、今後も継続的に評価し、より多くの看護師が NPE の運営方法を習得できる方法の検討を進める必要がある。With the aim of improving training for nurses involved in psychoeducation, this study was conducted to compare the effects of Nursing Psychoeducation (NPE) when implemented by nurses and its developers, focusing on differences in acquired knowledge of drug administration for patients and their disease conditions. Methods of intervention and data acquisition were as follows: The subjects were schizophrenic patients hospitalized in the Department of Psychiatry for acute-phase treatment, divided into two groups: the developer group received NPE provided by the developers, and patients in the nurse group participated in NPE implemented by practicing nurses who were trained by the developers. The two groups underwent the Knowledge of Illness and Drugs Inventory (KIDI) before and after receiving NPE. We conducted a paired t-test to compare the total KIDI and subscale scores of the two groups. The number of subjects in the developer and nurse groups were 16 each (32 in total). There were 18 males and 14 females, with a mean age of 40.21 (SD=13.71) years old. According to the results of analysis, the total KIDI and subscale (drug therapy) scores of the two groups following the intervention were significantly higher. The subscale score for psychiatric symptoms of the developer group after the invention was markedly higher. In general, NPE was similarly effective when implemented by the developers and nurses. To help as many nurses learn the implementation of NPE as possible, it is necessary to conduct evaluation on a continual basis and develop appropriate methods

本研究の目的は、早期退院を控えた統合失調症患者の服薬アドヒアランスに影響する要因を探索し、看護実践の示唆を得ることであった。対象者は、精神科急性期治療病棟に入院中の統合失調症患者22名(男性9名、女性13名)、平均年齢44.6±13.0歳、平均罹病期間12.7±13.5年、平均入院回数2.8±3.1回、心理教育参加者15名であった。データ収集は、心理教育開催時期に合わせ、開催前にデモグラフィックスデータ、治療状況、CP換算値、機能の全体的評価、服薬アドヒアランス、服薬と病気の知識を測定し、開催後にCP換算値、機能の全体的評価、服薬アドヒアランス、服薬と病気の知識を測定した。データ分析には、強制投入法による重回帰分析を用いた。結果、服薬アドヒアランスへの影響要因は、年齢、罹病期間、職業、心理教育参加、心理教育開催前の服薬アドヒアランス(MPS、DAI-10)であり、モデル全体の78 ～ 86%が有意に説明された。これより、患者の個人特性を考慮した服薬アドヒアランスを高める支援を模索する必要性と、心理教育が患者の服薬アドヒアランス改善に向けた看護援助になり得ることが示唆された。This study aimed to explore factors affecting drug adherence before hospital discharge in patients with schizophrenia, and determine the implications for nursing practice. The subjects were 22 patients with schizophrenia (male: 9, female: 13) who had been hospitalized in acute psychiatric units (mean age: 44.6±13.0 years, mean disease duration: 12.7±13.5 years, mean number of hospitalizations: 2.8±3.1 times) and 15 participants in a psychoeducational program. The subjects\u27demographic data, therapeutic situation, CP equivalents, assessment of overall function, drug adherence, and knowledge of medication and disease were measured before conducting the psychoeducational program, and CP equivalents, assessment of overall function, drug adherence, and knowledge of medication and disease were re-measured after the final session of the program. Data were forcibly entered into a multiple regression analysis. As the results, age, disease duration, occupation, participation in the psychoeducational program, and drug adherence at the initial measurement (MPS, DAI-10) were identified as factors affecting drug adherence, which significantly explained 78-86% of the variance. These results suggest the need for drug adherence support considering each patient\u27s individuality, and the possibility of employing a psychoeducational program to promote nursing support for improving a patient\u27s drug adherence

The position of a standard optical computer mouse affects cardiorespiratory responses during the operation of a computer under time constraints

Objectives: This study investigated the association between task-induced stress and fatigue by examining the cardiovascular responses of subjects using different mouse positions while operating a computer under time constraints. Material and Methods: The study was participated by 16 young, healthy men and examined the use of optical mouse devices affixed to laptop computers. Two mouse positions were investigated: (1) the distal position (DP), in which the subjects place their forearms on the desk accompanied by the abduction and flexion of their shoulder joints, and (2) the proximal position (PP), in which the subjects place only their wrists on the desk without using an armrest. The subjects continued each task for 16 min. We assessed differences in several characteristics according to mouse position, including expired gas values, autonomic nerve activities (based on cardiorespiratory responses), operating efficiencies (based on word counts), and fatigue levels (based on the visual analog scale – VAS). Results: Oxygen consumption (VO2), the ratio of inspiration time to respiration time (Ti/Ttotal), respiratory rate (RR), minute ventilation (VE), and the ratio of expiration to inspiration (Te/Ti) were significantly lower when the participants were performing the task in the DP than those obtained in the PP. Tidal volume (VT), carbon dioxide output rates (VCO2/VE), and oxygen extraction fractions (VO2/VE) were significantly higher for the DP than they were for the PP. No significant difference in VAS was observed between the positions; however, as the task progressed, autonomic nerve activities were lower and operating efficiencies were significantly higher for the DP than they were for the PP. Conclusions: Our results suggest that the DP has fewer effects on cardiorespiratory functions, causes lower levels of sympathetic nerve activity and mental stress, and produces a higher total workload than the PP. This suggests that the DP is preferable to the PP when operating a computer
