The State of Fatigue and Sleep among Clinical Nurses in Japan  [PDF]
Naomi Sumi, Naotaka Sugimura, Yuko Yoshida, Rika Yano
Open Journal of Nursing (OJN) , 2017, DOI: 10.4236/ojn.2017.712104
The objective of this study was to investigate the state of fatigue and sleep among clinical nurses in Japan. This descriptive cross-sectional study was conducted from December 2015 to January 2016. The participants were nurses who worked in public hospitals with 500 beds in the major cities and regional cities of Hokkaido. Fatigue was quantitatively assessed using the Cumulative Fatigue Symptoms Index (CFSI). Among nurses in their twenties, the rate of complaints about anxiety and decrease in vitality were high, which was replaced with complaints about irritability among nurses in their thirties. The most popular complaint among nurses in their forties was general fatigue. There was no difference in complaint ratios concerning the workplace location among nurses in their twenties and thirties, nurses in their forties working in suburban areas complained about fatigue more than their urban area. Nurses with sleep problems related to anxiety have a significantly higher complaint rate for all the eight items of CFSI compared with the nurses who do not have such problems (p < 0.001). This is an intermediate report and is part of a study that aims to develop a health management program for hospital nurses regarding fatigue and sleep.

Naomi Sumi, Yuko Yoshida, Naotaka Sugimura, Rika Yano
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.84022
Background: The purpose of this study was to elucidate the stages of nurse burnout in hospitals (their states of emotional exhaustion and depersonalization) as well as factors related to the nurses personal characteristics and coping behaviors in order to obtain suggestions for stress and health management strategies that nurses themselves can employ. Methods: We conducted a cross-sectional study using anonymous self-administered questionnaires. The subjects were nurses employed at public hospitals with 500 beds in 3 cities in Hokkaido, Japan. The questionnaire items for burnout were those included on the Japanese Maslach Burnout Inventory (MBI), which are designed to ascertain the subjects’ emotional exhaustion, depersonalization, and sense of personal accomplishment. In addition, we used 11 items related to physical and mental stress responses on the Stress Coping Inventory and the Brief Job Stress Questionnaire to determine factors such as the nurses’ basic attributes, whether or not they worked night shifts, and their overtime hours, etc. Results: We received responses from 1461 hospital nurses. Those whose scores for both emotional exhaustion and depersonalization were the mean or above were 40.2% of those in their twenties, 35.8% of those in their thirties, and 26.8% of those in their forties or older. The results of logistic regression analysis indicated that among those in the group that scored high for both emotional exhaustion and depersonalization, the influential factors were stress score (odds ratio 1.889), twenties age group (odds ratio 1.982), thirties age group (odds ratio 1.720), coping behavior: avoidance-focused behaviors (odds ratio 1.140), and engaged in childcare (odds ratio 0.487). Similarly, when looked at by age group, being in the twenties age group and having a spouse were influential factors (odds ratio 3.114 - 4.171).
Relationship between Sleep and Subjective Fatigue in Rotating Shift Nurses: Validation Using a Wearable Device  [PDF]
Yuko Yoshida, Naomi Sumi, Naotaka Sugimura, Fumie Nemoto, Rika Yano
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.84023
The objective of this study was to determine if sleep indicators are associated with subjective fatigue in nurses working in a rotating, two-shift system with a 16-hour night shift, using the wearable device Fitbit One. Subjective fatigue was evaluated using the Subjective Fatigue Symptom Questionnaire (SFSQ), a rating scale developed by the Working Group for Occupational Fatigue of the Japan Society for Occupational Health. Subjects were asked to continuously wear a Fitbit One to obtain the following data: time in bed (TIB), deep sleep time, length and frequency of nighttime awakening, sleep efficiency, waking time, and bed time. Nurses had a mean age and standard deviation of 33.2 ± 7.5 years and had worked as nurses for 9.8 ± 6.2 years on average. Eight nurses were in their 20s (42.1%), 5 in their 30s (26.3%), and 6 in their 40s (31.6%). All participants were female. Participants SFSQ scores calculated from the 9 evenings in the study period were averaged to establish a threshold for categorizing high-fatigue (HF) and low-fatigue (LF) groups. No significant differences were found between HF and LF nurses in terms of TIB, deep sleep time, nighttime awakening time or frequency, or sleep efficiency on any type of day (as classified by shift, day off, etc.). Nurses in both groups woke up significantly later on days off and on pre-night-shift days than on day-shift days. These results demonstrate the variation in sleep patterns of nurses on a rotating, two-shift system between day-shift and night-shift days.

Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.72025
Abstract: In our previous studies, we examined the relationship between changes in mood, verbal (semantic) behavior, and non-verbal (skin temperature) activity induced by inhalation of essential oil fragrances, as well as linalool and its enantiomers. Sensory evaluation was a key component of these studies. We have found that perceived sensory attributes reported by participants can be represented via sensory spectrograph: A bar graph where the mean of the impression is plotted against descriptors of the setting for the semantic impression. In this paper, we present our latest attempts at assessing the taste of food using a sensory spectrograph. We conducted two studies: One in which participants assessed the taste of cookies with or without bean curd lees and one in which participants evaluated the taste of Miso soup and Sumashi soup as a function of salty concentration and soup stock consistency.
Outside the Cage: Exploring Everyday Interactions between Government Workers and Residents in a Place-Based Health Initiative  [PDF]
Naomi Sunderland
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.31008
Abstract: This paper presents an ethnographic case study of the daily lived experience of place by government health and community workers in a place-based chronic disease initiative (PBI) located in a disadvantaged peri-urban area in Australia. The case study focused on the place at which the PBI staff members interfaced with the community informally as opposed to the deliberate interactions described in the formal community engagement strategy. Subtle social phenomena, such as social positioning and the contrasting cultures of bureaucracy and community, generated outcomes that were the antithesis of those sought by the PBI. If these characteristics of place are not attended to during the development of PBIs, we risk recreating existing social divides and jeopardizing the potential of these initiatives to build community capacity. This case study provides an important conceptual-theoretical understanding of the place-based approach, which can augment existing empirical studies of place. The findings are also relevant for those who are exploring the physical co-location of diverse professional groups in socially disadvantaged neighbourhoods. It also exposes the inherent complexity of place and the futility of poorly designed bureaucratic responses.

Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.47059

The objective of this study was to conduct a nation-wide survey to investigate the state of: 1) the prevalence of psychological preparation of children undergoing surgery; and 2) the awareness of psychological preparation of children by medical professionals (physicians and nurses). We also aimed to identify the issues that need to be addressed next. A total of 178 physicians and 291 nurses working in hospitals where children undergo surgeries participated in this study. Anonymous self-administered questionnaire survey. Physicians and nurses in Japan are aware of the need to provide age-appropriate psychological preparation for children undergoing medical procedures. In current practice, however, our study revealed that surgical orientations are given solely to parents in the absence of the child in approximately 30% of cases. While approximately 60% of respondents felt that the uses of “children’s picture books and booklets” are good methods for delivering explanations to children, only about 20% of respondents were implementing psychological preparation specific to each age group, and half of the respondents were providing verbal explanations alone. Meanwhile, 77% responded that it is “time-consuming” and 48% said, “on the contrary, it may heighten their anxiety”. Also 34.3% said that they “do not know how to explain to a child” and 54.8% of these medical professionals worked in mixed wards. We observed a gap between ideal requirements and current practices. We found that it is essential to: 1) organize training sessions for knowledge acquisition; 2) consciously strive to be informed of the actual post-surgery conditions and outcomes of the children; and 3) acquire physical and financial support.

Determination of Lateral Modulation Apodization Functions Using a Regularized, Weighted Least Squares Estimation
Chikayoshi Sumi
International Journal of Biomedical Imaging , 2010, DOI: 10.1155/2010/635294
Abstract: Recently, work in this group has focused on the lateral cosine modulation method (LCM) which can be used for next-generation ultrasound (US) echo imaging and tissue displacement vector/strain tensor measurements (blood, soft tissues, etc.). For instance, in US echo imaging, a high lateral spatial resolution as well as a high axial spatial resolution can be obtained, and in tissue displacement vector measurements, accurate measurements of lateral tissue displacements as well as of axial tissue displacements can be realized. For an optimal determination of an apodization function for the LCM method, the regularized, weighted minimum-norm least squares (WMNLSs) estimation method is presented in this study. For designed Gaussian-type point spread functions (PSFs) with lateral modulation as an example, the regularized WMNLS estimation in simulations yields better approximations of the designed PSFs having wider lateral bandwidths than a Fraunhofer approximation and a singular-value decomposition (SVD). The usefulness of the regularized WMNLS estimation for the determination of apodization functions is demonstrated. 1. Introduction A beamformer and a transducer are used in applications such as medical ultrasound (US) imaging, blood flow measurement, tissue displacement/strain measurements, and sonar measurements. For these applications, US beamforming parameters such as US frequency, US bandwidth, pulse shape, effective aperture size, and the apodization function are chosen or selected, and appropriate values are set. In addition, US transducer parameters such as the size and materials used for the US array elements are also chosen. In choosing such settings, the US properties of the target are also considered (e.g., attenuation and scattering). Thus, all of the above parameters must be appropriately chosen and set when considering a system that involves the US properties of the target. In general, such parameters are chosen using the knowledge and experience of an engineer. Recently, a cosine modulation (LCM) method [1–3] was described that was used for US echo imaging [3, 4] and tissue displacement vector measurements (blood, soft tissues, etc.) [3, 5] using the multidimensional autocorrelation method (MAM) [1], the multidimensional Doppler method (MDM) [1], and the multidimensional cross-spectrum phase gradient method (MCSPGM) [6]. Specifically, for instance, in US echo imaging, a high lateral spatial resolution as well as a high axial spatial resolution can be obtained, and in tissue displacement vector measurements, accurate measurements of lateral as
Peut-on parler de millénarisme à l'′époque carolingienne? l'apport de quelques sources exégétiques
Temas medievales , 2006,
Abstract: millenarianism was officially condemned at the start of the middle ages, but it reappeared, although with less weight, at different moments and places. historians studying the high middle ages have at their disposal few written sources which would prove the existence of any such beliefs and their interpretations vary. thus, if millenarianism did exist during the carolingian period, we must assume that it did so discreetly and in specific cases. no source mentions it as being a dangerous heresy. the analysis of certain exegetical sources proves that some orthodox statements are not an answer to any verified erroneous beliefs, but that they belong to the tradition of written predication. therefore, an interpretation based on their absence in the sources ought to be used carefully in view of the present lack of any written proof of their existence.
Utilization of an ultrasound beam steering angle for measurements of tissue displacement vector and lateral displacement

Abstract: ilization of an ultrasound beam steering angle for measurements of tissue displacement vector and lateral displacement Original Research (4457) Total Article Views Authors: Chikayoshi Sumi Published Date September 2010 Volume 2010:3 Pages 61 - 81 DOI: http://dx.doi.org/10.2147/RMI.S11407 Chikayoshi Sumi Department of Information and Communication Sciences, Faculty of Science and Technology, Sophia University, Tokyo, Japan Abstract: A number of ultrasonic displacement/velocity measurement methods have been extensively developed for measurements of blood flow, tissue motion, and strain. Lateral modulation (LM) methods have also been reported using steered, crossed beams, and these methods permit measurements of displacement vectors. In this report, a new beam steering method for the transmission and reception of ultrasound is proposed, which can enable measurements of lateral displacements and of arbitrary displacement vectors with a very high degree of accuracy. Because this beam steering method uses only a steering angle, this method is referred to as ASTA. With ASTA, the number of available methods to obtain a displacement vector measurement is limited to previously developed block-matching methods, such as the multidimensional cross-spectrum phase gradient method, and the multidimensional autocorrelation method (MAM) and the multidimensional Doppler method (MDM) using a block-matching method (the methods using block matching are referred to as MAMb and MDMb, respectively). Being dependent on the measurement method, only a lateral displacement measurement can be made even if the methods are multidimensional, ie, previously developed MAM and MDM using a moving average and a mirror setting of the obtained steered beams, and one-dimensional (1D), such as an autocorrelation method. Considerations of beamforming schemes using LM and ASTA show that the simple ASTA beamforming method increases capabilities for real-time measurements and requires a small physical aperture when compared with LM. For lateral displacement measurements (eg, blood flow in a carotid artery), a lateral coordinate must correspond to the direction of the target’s lateral motion, and the steering angle used is as large as possible to increase the measurement accuracy of a lateral displacement. However, for displacement vector measurements to describe complex tissue motions (eg, cardiac motion), if the axial coordinate corresponds to the depth direction in the target tissue, an ideal steering angle will be 45°. A two-dimensional echo simulation shows that for the block-matching methods, LM yields more accurate displacement vector measurements than ASTA, whereas with MAM and MDM using a moving average and a mirror setting and 1D methods, ASTA yields more accurate lateral displacement measurements than LM. The block-matching method requires fewer calculations than the moving average method; however, a lower degree of accuracy is obtained. As with LM, multidimensional measurement met
Is Korean Really a Listener-Responsible Language like Japanese?: A Contrastive Analysis of Discourse in Apologies between Korean and Japanese
Acta Linguistica Asiatica , 2011,
Abstract: According to Hinds’ typology of languages on discourse level, Japanese and Korean are both considered listener-responsible languages, whereas English is classified as a speaker-responsible language (Hinds, 1987). However, in conversation, Yoon (2009) demonstrated that Korean should be classified as a speaker-responsible language based on her contrastive analysis of daily conversations between married couples in Japanese and Korean, where address terms and fillers are used as contextualization cues (Gumperz, 1982) to convey a speaker's intention to the interlocutor metacommunicatively. The purpose of the present study is to show that Japanese is listener-responsible, while Korean is a speaker-responsible language on the level of conversational communication. In order to test the hypothesis, surveys and recordings of real conversations of Japanese and Korean people were conducted and analyzed.The informants in the present study consisted of four groups: Japanese university students who live in their own country, Japanese university students who live in the U.S., Korean university students who live in their own country and Korean university students who live in the U.S. A Discourse Complete Test (DCT) was completed by Japanese and Korean university students to compare the differences in speaker responsibility in apologies. The results suggest that Korean should be classified as a speaker-responsible language for understanding in conversations, since Korean speakers produce many more utterances and convey more information per utterance to the interlocutor than Japanese speakers. Furthermore, it is found that the responsibility for the understanding of utterances correlate with daily use of American English, especially in the case of Japanese university students.
