Background: While demonstration videos from a third-person perspective have traditionally been used as teaching materials for nursing skills, first-person videos allow observers to experience how nursing educators move and what they see. In this pilot study, a first-person demonstration video for tracheostomy suctioning skills was shown to participants via a virtual reality (VR) head-mounted display (HMD), which we referred to as a VR teaching material (VR-TM). In an intervention experiment, we investigated the effects of the VR-TM on participants’ performance on the skill assessment test. Additionally, usability of the VR-TM was evaluated by questionnaire ratings. Methods: Thirty-six participants (nursing students) were assigned to three groups in the experiment: 1) VR group: the participants that viewed the VR-TM, 2) TR group: the participants that viewed a traditional demonstration video from a third-person perspective, and 3) NO group: the participants that received no intervention. Score changes in the skill assessments of participants before the intervention (pre-test) and after the intervention (post-test) were analyzed. After the experiment, all participants completed a faculty-designed questionnaire about the VR-TM usability. Results: The questionnaire ratings indicated that the participants evaluated the VR-TM favorably in terms of skill understanding and motivation to practice the skill. However, one-third of participants reported mild discomfort during the VR-TM. In regards to score changes in the skill assessment test, no significant difference between the VR and TR groups was identified, though the two groups produced greater score changes compared to the NO group. Conclusion: The combination of first-person video and the HMD might be promising as a teaching material for nursing skills, though further improvements are necessary.

Emotion Measurement Using Biometric Signal

引用

Health 2024年第5期16卷 395-404页

In recent years, research on the estimation of human emotions has been active, and its application is expected in various fields. Biological reactions, such as electroencephalography (EEG) and root mean square successive difference (RMSSD), are indicators that are less influenced by individual arbitrariness. The present study used EEG and RMSSD signals to assess the emotions aroused by emotion-stimulating images in order to investigate whether various emotions are associated with characteristic biometric signal fluctuations. The participants underwent EEG and RMSSD while viewing emotionally stimulating images and answering the questionnaires. The emotions aroused by emotionally stimulating images were assessed by measuring the EEG signals and RMSSD values to determine whether different emotions are associated with characteristic biometric signal variations. Real-time emotion analysis software was used to identify the evoked emotions by describing them in the Circumplex Model of Affect based on the EEG signals and RMSSD values. Emotions other than happiness did not follow the Circumplex Model of Affect in this study. However, ventral attentional activity may have increased the RMSSD value for disgust as the β/θ value increased in right-sided brain waves. Therefore, the right-sided brain wave results are necessary when measuring disgust. Happiness can be assessed easily using the Circumplex Model of Affect for positive scene analysis. Improving the current analysis methods may facilitate the investigation of face-to-face communication in the future using biometric signals.

Nursing Activities at Health Surveys and Health Checkups during the Early Period of Operation of the Hiroshima ABCC—Oral History Study Based on Narratives of Three Japanese Nurses

引用

Open Journal of Nursing 2018年第1期8卷 69-77页

作者： saori Funaki Mizue Shiromaru Department of Nursing School of Health Sciences Sapporo Medical University Sapporo Japan

Using an oral history approach, this study analyzed the narratives obtained from semi-structured interviews administered to three Japanese women who worked as nurses for the Hiroshima Atomic Bomb Casualty Commission (ABCC). The analysis of the data in the narratives showed details of the health surveys and health checkups conducted during the early period of operation of ABCC. During the early period of operation of ABCC some survivors showed negative behaviors toward the health surveys and health checkups at the ABCC. However, it can be inferred that dedicated nursing played an important role in alleviating the stress and emotional issues of survivors at the health surveys and health checkups. The findings of the study could be beneficial to research into nursing activities for patients exposed to radiation at the present day.

Journal of Civil Engineering and Architecture 2013年第6期7卷 698-703页

作者： saori Nakajima Akiko Watanabe Graduate School of Science and Technology for Future Life Tokyo Denki University Tokyo 120-8551 Japan Department of Architecture Tokyo Denki University Tokyo 120-8551 Japan

In this paper, the authors present a basic study of the planning techniques for human-robot living spaces. Taking into account the previous studies, the authors clarify at what distances adult males feel comfortable with a small mobile robot. The authors investigated the impact of differences in position in a personal distance of the robot. The authors make the robot to move towards the subjects at different speeds and from five different angles （0°, 45°, 90°, 135° and 180°） while they were crouching, sitting on the floor and supine. In this experiment, about setting up a small mobile robot, the authors explained the robot does not have a support function for the people watching. A questionnaire survey was also conducted before and after the experiments. The result is that differences were out to personal distance with the robot due to the difference in position. The research finds that personal distance also becomes small position changes, sight line becomes lower. In addition, individual distance is increased when the slow speed as well as the paper before.

ERK phosphorylation functions in invadopodia formation in tongue cancer cells in a novel silicate fibre-based 3D cell culture system

引用

International Journal of Oral Science 2018年第4期10卷 253-262页

To screen for additional treatment targets against tongue cancer, we evaluated the contributions of extracellular signal-related kinase(ERK), AKT and ezrin in cancer development. Immunohistochemical staining showed that ERK and ezrin expressions were significantly higher in invasive squamous cell carcinoma than in carcinoma in situ. To investigate the roles of ERK and ezrin in cancer development, we used the non-woven silica fibre sheet Cellbedwith a structure resembling the loose connective tissue morphology in a novel 3 D culture system. We confirmed that the 3 D system using CellbedTMaccurately mimicked cancer cell morphology in vivo. Furthermore, cell projections were much more apparent in 3 D-cultured tongue cancer cell lines than in 2 D cultures. Typically, under conventional 2 D culture conditions, F-actin and cortactin are colocalized in the form of puncta within ***, in the 3 D-cultured cells, colocalization was mainly observed at the cell margins, including the projections. Projections containing F-actin and cortactin colocalization were predicted to be invadopodia. Although suppressing ezrin expression with small interfering RNA transfection caused no marked changes in morphology, cell projection formation was decreased, and the tumour thickness in vertical sections after 3 D culture was markedly decreased after suppressing ERK activity because both the invasion ability and proliferation were inhibited. An association between cortactin activation as well as ERK activity and invadopodia formation was detected. Our novel 3 D culture systems using Cellbed? are simple and useful for in vitro studies before conducting animal experiments. ERK contributes to tongue cancer development by increasing both cancer cell proliferation and migration via cortactin activation.

Diurnal Periodicity of the Expression of Genes Involved in Monolignol Biosynthesis in Differentiating Xylem of Cryptomeria japonica

引用

American Journal of Plant Sciences 2016年第17期7卷 2457-2469页

作者： saori Sato Masato Yoshida Yousuke Ashizaki Hiroyuki Yamamoto Laboratory of Bio-Material Physics Graduate School of Bioagricultural Sciences Nagoya University Nagoya Japan

The cell wall in wood is mainly composed of three components: cellulose, hemicellulose and lignin. According to electron microscopy observations of the innermost surface of cell walls in the tracheids of Cryptomeria japonica , cellulose microfibrils are deposited during the day and a matrix containing hemicellulose is deposited at night. This indicates that the deposition of cell wall components exhibits diurnal periodicity. To gain new insights into the diurnal periodicity of lignin deposition not revealed by microscopic observations, we examined diurnal fluctuations in the expression of genes involved in monolignol biosynthesis in C. japonica saplings grown in the field and in growth chambers under a 12 h light/dark cycle. In the field experiment, two gene expression peaks were observed daily, at dusk and dawn. In the growth chamber experiment, two daily peaks were observed 0 h and 6 - 9 h after the light switched on.
