36-Month Follow-Up Study of Post-Intervention Chronic Heart Failure Patients  [PDF]
Haruka Otsu, Michiko Moriyama
Health (Health) , 2014, DOI: 10.4236/health.2014.67075
Abstract: Aim: Although numerous studies of disease management and case management of chronic heart failure (CHF) have been carried out, length of effectiveness after program commencement has not been examined, so we examined a follow-up study at 36 months after program commencement. Methods: Participants went for follow-up visits to one Japanese clinic which specializes in internal cardiovascular medicine and they were given diagnoses of CHF. 104 outpatients participated in this study and randomized control trial was implemented. An educational program was implemented for 6 months. The data were collected at baseline, 3, 6, 9, 12 months from both intervention and control groups and at 24 and 36 months from the intervention group. Results: There was significant improvement in New York Heart Association (NYHA) in the intervention group between baseline and 36 months. Improvement in weight monitoring and activities or exercise in the intervention group continued up to 36 months. Meanwhile, sodium restricted diets and quitting smoking and/or drinking depended on individual preference and it was difficult to make improvements in these areas. Conclusions: The educational program showed promise in preventing CHF outpatients from deteriorating significantly on a long-term basis as self-monitoring of activity and weight continued significantly and there were no participants with CHF who deteriorated in the intervention group at 36 months after program commencement, although the program aimed only to provide illness and self-management knowledge. On the other hand, future work will need to compare participants in this program to a control group over an extended period of time with consideration for relieving the burden of the control group.
Assessment of a portfolio as an effective tool to promote self-management among patients with ischemic heart diseases: A preliminary trial  [PDF]
Haruka Otsu, Michiko Moriyama, Yuasa Yuka, Toyonori Omori
Health (Health) , 2014, DOI: 10.4236/health.2014.65053
Abstract:

Portfolio has been used as an approach to promoting self-learning in the field of education and its effectiveness was reported in school education. The purpose of this study was to assess effectiveness of portfolio as a tool for educating patients with ischemic heart diseases as self-management behavior in terms of applicability and efficacy. Subjects of this study were seventeen patients who had myocardial infarction or angina. They were assigned to collect information about their themes chosen from diet, exercise, alcohol intake, smoking cessation, and stress management and gathered in files. Thirty minutes face-to-face educational interviews were conducted by a nurse for once per month over three months. Self-management, self-efficacy, and physiological data were evaluated for baseline and 3 months. Two participants dropped within two months (completion rate is 88.2%). The results showed that portfolio was effective as a self-management education tool on patients who were willing to participate, but did not improve physiological data if they did not continuously implement lifestyle change. Moreover it was dangerous when the patients acquired incorrect information on diseases. For these patients, health education by health professionals is required prior to conducting portfolio. Attributes fit for portfolio were assessed. Effectiveness of portfolio related to high self-efficacy and high self-management, but did not relate to living status, having job, educational background, and health locus of control.

Characteristics of Patients with Decreased Cognitive Function Undergoing Treatment for Acute Exacerbation of Chronic Heart Failure—Basic Survey for Standardization of Nursing to Prevent Discontinuation of Treatment  [PDF]
Haruka Otsu, Toshiko Inoguchi, Michiko Moriyama, Shigeko Takayama, Yoko Watanabe, Masayo Kume
Health (Health) , 2018, DOI: 10.4236/health.2018.105052
Abstract: The purpose of this study is to clarify the characteristics of patients with decreased cognitive function undergoing treatment for acute exacerbation phase of chronic heart failure as a basic survey with a view to the standardization of nursing to prevent discontinuation of treatment of patients with declining cognitive function in the acute exacerbation phase of chronic heart failure. As the first stage of the research, using the interview guide created based on the background of discontinuation of treatment and symptomatic monitoring from 33 target literature sources, seven certified chronic heart failure nurses and 15 certified dementia nurses were given semi-structured interviews. Data obtained from the interviews was analyzed by qualitative induction. As a result, we obtained opinions/views on 8 situations namely, “cognitive function at hospitalization”, “characteristics at hospitalization, “characteristics when receiving examinations, procedures or treatment”, “characteristics of course of treatment”, “characteristics related to difficulties in grasping the symptoms of chronic heart failure and indices of deterioration”, “characteristics when using diuretics”, “characteristics concerning compliance with dietary restrictions” and “support required for discharge from hospital” concerning patients with declining cognitive function. In the future, it is necessary to prepare nursing protocols incorporating these contents for standardization of nursing.
Development of Nursing Protocol for Preventing Interruptions during Clinical Examinations and Treatments in the Early Days of Hospitalization for Acute Exacerbation of Chronic Heart Failure in Patients with Impaired Cognitive Function  [PDF]
Haruka Otsu, Hiroko Yokotani, Natsuko Jukei, Yoshiko Sakai, Shigehito Narita, Tamao Susukida, Miho Tsujino
Health (Health) , 2018, DOI: 10.4236/health.2018.106059
Abstract: The purpose of this study is to prepare a nursing protocol for preventing interruptions during clinical examinations and treatments performed in the early days of hospitalization for acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the research, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 11 nurses in dementia care to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 73 subjects (84.9%) considered effective for patients, in terms of prevention of interruptions during clinical examinations and treatments in the early days of hospitalization. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 84.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We consider that this nursing protocol will be useful especially for newly graduated/employed nurses as a procedure manual which can reduce their anxiety or stress caused by lack of knowledge or experiences.

Health (Health) , 2018, DOI: 10.4236/health.2018.106060
Abstract: The purpose of this study is to prepare a nursing protocol for preventing discontinuation of treatments using a method other than physical restraint during acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the study, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 10 nurses in dementia case to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 154 subjects (93.9%) considered effective for patients, in terms of prevention of treatment discontinuation using a method other than physical restraint. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 93.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We also received a comment from the certified nurses that we should include the basic contents for newly graduated nurses. We consider that this nursing protocol will be also useful for newly graduated nurses to acquire knowledge. It helped to standardize nursing care in order to predict potential risks for patients with impaired cognitive function.
Development of a Nursing Protocol for Hospitalized Patients with Reduced Cognitive Function in the Process of Recovery from Acute Exacerbation of Chronic Heart Failure  [PDF]
Haruka Otsu, Tsukiko Narasaki, Ayumi Kamura, Kyoko Maeda, Tomoko Sumiwaka, Tomie Uno, Misato Takamori, Toshimichi Wada
Health (Health) , 2018, DOI: 10.4236/health.2018.107065
Abstract: The purpose of this study is to develop a nursing protocol aiming at early recovery of hospitalized patients with reduced cognitive functions in the process of recovery from acute exacerbation of chronic heart failure. At the first stage of the research, a draft nursing protocol was prepared based on a basic survey. At the second stage of research, a semi-structured interview was conducted for 4 nurses certified for chronic heart failure nursing and 11 nurses certified for dementia nursing so as to ensure content validity of the draft nursing protocol. At the third stage of the study, the possibility of clinical application of the nursing protocol revision plan proposed at the second stage of the study was examined. The nursing protocol revision plan was effective for 118 nurses (90.1%) who carried out the protocol for the target patient on assessment items, essential points of nursing care and specific nursing care. There were no items or contents for which confirmation of usefulness was less than 60%. Since 90.1% of the usefulness was confirmed by nurses working in the actual clinical setting, the authors believe that this nursing protocol was secured to a certain level. The nursing protocol developed in this study has been requested by nurses at clinical sites in the past. It is very meaningful in improving nursing for the early recovery of hospitalized patients with reduced cognitive function in the process of recovery from acute exacerbation of chronic heart failure.
An Implementation of the Japanese Autobiographical Method Seikatsu Tsuzurikata—“Life Writing”—In a US Elementary School  [PDF]
Scott Richardson, Haruka Konishi
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.49080
Abstract:

This article explores the historical, philosophical, curricular, and practical methods of the Japanese auto-biographical method, “seikatusu tsuzurikata” and its implementation in a US elementary school. Seikatsu tsuzurikata is a progressive form of journaling that “provokes students to ‘objectively’ observe the reality surrounding them in terms of their own senses without any intervention of anyone else’s authority”, by writing essays “reflecting on their social situation” (Asanuma, 1986: pp. 153, 155). Part of life writing’s central philosophy is that students are not required to participate. For students who engaged in life writing, several benefits resulted, according to their teachers. However, we found that students had great difficulty articulating their social and emotional worlds because this kind of reflective work was uncomfortable and foreign to students who were subjected to teacher-driven, “content”, and “standards based” instruction. This article concludes by exploring the possibility of connecting life writing with social-emotional learning (SEL).

The Organization of the Senses of Polysemy in Japanese EFL Learners’ Mental Lexicon  [PDF]
Yuko Hoshino, Haruka Shimizu
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.93025
Abstract: The structure of the mental lexicon has been widely researched, but few studies focusing on polysemy have been conducted, even in an L1 (a learner’s first language) context, and almost no research has been conducted in an L2 (a learner’s second language) context. The current study aims to scrutinize how the different vocabulary size groups of Japanese EFL learners classify the various senses of basic polysemous words and to compare their categorization with sense classification based on a linguistic dictionary. The results indicated that those with an estimated vocabulary size consisting of 5500 words or over (hereafter, the upper group) classified senses in a more similar way to the dictionary than those whose vocabulary size comprised 5000 or fewer words (hereafter, the lower group). This was despite the fact that they both understood the target context well and the number of categorizations created was almost the same between the two groups. Moreover, the upper group tended to classify the senses of polysemy in a more similar way to the other participants in the same vocabulary group, while the lower group’s categorization was more divergent and less well-organized. These findings indicated that even though the participants understood each sense, the difference appeared in the ability to categorize the senses, suggesting that grouping the senses needs knowledge different from simply understanding them, and this knowledge is not yet fully developed even for basic words.
The Decline of Village Common Lands and Changes in Village Society: South India, c. 1850-2000
Yanagisawa Haruka
Conservation & Society , 2008,
Abstract: The widely accepted view that emphasises the negative impact of the decline in common property re-sources on the village poor generally presumes that village common lands would have been used by all villagers inclusive of the poor without serious differences in the right to access them. Mainly based on historical documents for Tamil Nadu from the nineteenth century, this paper argues that influential vil-lagers controlled ′waste lands′ (village common land) and that this elite-dominant system of controlling natural resources declined with the gradual emancipation of the subordinate section of villagers. The ac-quisition of small bits of cultivated land and the encroachment on waste lands by the landless not only mirrored their empowerment and strengthened their bargaining position but also implies, under some cir-cumstances, the creation of possible pre-conditions for an egalitarian type of resource-controlling system. This paper also suggests that, as witnessed in Tamil Nadu in the last two decades, the growth of non-agricultural job opportunities could possibly weaken the pressure on lands and also induce farmers to change cropping patterns of their farms, sometimes leading to an expansion of farm forestry. The acquisi-tion of landholding by the landless and their emancipation could also possibly contribute in this direction.
The effect of the north-east ice stream on the Greenland ice sheet in changing climates
R. Greve,S. Otsu
The Cryosphere Discussions , 2007,
Abstract: The north-east Greenland ice stream (NEGIS) was discovered as a large fast-flow feature of the Greenland ice sheet by synthetic aperture radar (SAR) imaginary of the ERS-1 satellite. In this study, the NEGIS is implemented in the dynamic/thermodynamic, large-scale ice-sheet model SICOPOLIS (Simulation Code for POLythermal Ice Sheets). In the first step, we simulate the evolution of the ice sheet on a 10-km grid for the period from 250 ka ago until today, driven by a climatology reconstructed from a combination of present-day observations and GCM results for the past. We assume that the NEGIS area is characterized by enhanced basal sliding compared to the "normal", slowly-flowing areas of the ice sheet, and find that the misfit between simulated and observed ice thicknesses and surface velocities is minimized for a sliding enhancement by the factor three. In the second step, the consequences of the NEGIS, and also of surface-meltwater-induced acceleration of basal sliding, for the possible decay of the Greenland ice sheet in future warming climates are investigated. It is demonstrated that the ice sheet is generally very susceptible to global warming on time-scales of centuries and that surface-meltwater-induced acceleration of basal sliding can speed up the decay significantly, whereas the NEGIS is not likely to dynamically destabilize the ice sheet as a whole.
