Miwa Yamamoto
International Journal of Clinical Medicine (IJCM) , 2011, DOI: 10.4236/ijcm.2011.25099
Abstract: This study aimed to clarify the dilemma of nurses working in general wards who face the ethical dilemma of restraining older people with dementia in Midwestern Japan. The study used the questionnaire method with an independently prepared questionnaire. The questionnaire was designed to ensure privacy and anonymity. The privacy and anonymity of study participants was assured. Of the 340 survey questionnaires distributed, 291 (85.6%) completed surveys were eligible number (12 additional surveys were returned without answers). An explanatory factor analysis revealed four dilemma factors among 15 items investigated (KMO value 0.84). These were: factor 1: “Execution of treatment and security,” α = 0.91; factor 2: “approach in the nursing of older people with dementia,” α = 0.93; factor 3: “A cooperative relationship in nursing of older people with dementia,” α = 0.87; and factor 4: “Priorities in nursing,” α = 0.81. The cumulative contribution ratio was 79.1%. We suggest that the program would enable nurses to cope with these dilemmas.
The effects of ethical dilemmas regarding the use of physical restraints in eldercare on female nurses who care for their relatives in Japan  [PDF]
Miwa Yamamoto
Open Journal of Nursing (OJN) , 2012, DOI: 10.4236/ojn.2012.22006
Abstract: Purpose: This study sought to clarify the relationship between a nurse’s exposure to elderly relatives and their perspective in using restraints on the elderly in health care situations. Methods: We approached nursing staff supervisors at 17 general hospital wards and explained the objectives of the study. Supervisors at 14 hospitals agreed to participate, giving us a sampling pool of 1929 nurses. We used a chi square test to compare nurses who had spent time with elderly relatives and those who had not on several variables related to using restraints on elderly patients. Results and Conclusion: This study found that nurses who live with elderly family members were significantly more likely to believe that restraints cause diseases (including chronic diseases) based on a chi square test (p < 0.05). Therefore it would be important that essential was the experiences of individuals with elderly family members when making programs of decreasing nurse’s dilemma to restraining the elderly.

Yusuke Sakurai, Miwa Yamamoto
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.89047
Abstract: Background: The Ministry of Public Management, Home Affairs, Posts and Telecommunications announced that the proportion of elderly people aged 65 or over in the total population of Japan reached a record high of 26.7% in the present Japan. Aims: This paper aimed to clarify from acute ward nurses’ concepts of life and death in Japan. Methods: Questionnaires were distributed to 720 nurses working in acute care hospital A in the Kansai area in Japan. Distribution destinations were all wards except for operating rooms and outpatient clinics. We initially classified the 27 items from Hirai et al.’s death and life scale into the initial seven factors (via promax rotation). Operational Definition: In my analysis, I relied considerably on the seven-point Likert scale of the Concept of life and death. Ethical Considerations: The present study was approved by the Tottori University Ethics Review Committee (1603 A 156). Results: The initial factor analysis revealed that 10 of the 27 items were inadequate. Thus, a second analysis was conducted on the remaining 17 items. The KMO analysis produced a value of 0.8. A Bartlett’s test produced a significant result (p < 0.001), and Cronbach’s α was 0.8, which was the result obtained during initial scale validity checks. The present analysis led to the extraction of 4 factors with eigenvalues greater than 1, with a cumulative contribution rate of 62.8%. Consideration: The first factor comprised all subscales except for the “death avoidance” subscale, which fit better within the fourth factor. These factors included “A comprehensive view of life and death” “Sharing the fate of death and liberation” “Death fear, anxiety, and avoidance”, and “Liberation from life and a world after death”.
Culturally Sensitive Medical Care and Nursing Support: A Study of the Concerns of Foreign Visitors to Japan  [PDF]
Yuki Murase, Miwa Yamamoto
Open Journal of Nursing (OJN) , 2019, DOI: 10.4236/ojn.2019.93031
Abstract: Background: Considering the development of international transportation in modern societies, nursing care needs to be sensitive to the cultures and customs of patients from other countries. The purpose of this study is to determine, from the perspective of culturally sensitive nursing support, the cultural practices that foreigners consider important when they visit a Japanese hospital for check-ups or hospitalization. Methods: A survey was completed by 110 foreign participants at a shrine in Kyoto City. The purpose of the survey was to evaluate the concerns of foreign visitors regarding Japanese medical providers, caused by cultural differences such as customs of daily life. The statistical analyses were performed using descriptive statistics as well as cross-tabulation, chi-square, and Fisher’s exact tests. Results: After grouping participants by continent, the top concerns observed in all groups about visiting a Japanese hospital were accessibility to and cost of medical care. First, as for medical facilities, participants from North and South America (North and South American) and Europe (Europeans) were significantly more concerned than those in Asia (Asians) (P < 0.01). Second, North and South American and Oceanians were more concerned about accessibility of medical care than Asians (P < 0.05), and Europeans more than Asians (P < 0.01). Third, North and South American, European, and Oceanian participants were more concerned about the duration of hospitalization than Asian participants (P < 0.01). Finally, Asian participants showed more concern regarding the gender of medical staff than European participants (P < 0.05). Conclusion: Nurses need opportunities to learn and understand differences in cultures. If nurses have opportunities to learn cultural differences as well as to experience caring for foreign patients, their competencies in culturally sensitive nursing support will improve over time. It can be said that this is an issue not only in Japan but also in all other countries.
Relationship between Cognition and Activities of Daily Living in Elderly Women with Mild Cognitive Impairment in Japan  [PDF]
Miwa Yamamoto, Kyoko Izumi, Yoko Aso
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.34050
Abstract: Purpose: This study aims to examine the relationship between cognition and ADL in elderly women with MIC. Methods: Cognitive function was assessed using a 4-item instrument screening for dementia. Each item was scaled from 1 to 4. The Katz Index was used to Participants (N = 680) were asked to return the completed questionnaire in the sealed envelope provided. The study received approval from the human subject’s ethics committee at Osaka University. Results and Conclusion: Participants’ mean age was 78.2 ± 6.5 years old. The age range of participants was 65 to 97 years old. Associations were not statistically significant between cognitive function and family structure. However, associations were significant for ADL items involving excretory failure (OR = 3.5, p = 0.000 in 2004, OR = 2.9, p = 0.000 in 2005; P < 0.05) using a logistic regression analysis adjusted for age. Therefore, we recommend that nurses work to educate the public about treatment-adjusted dementia in the community, teaching family members or caretakers to observe the ADL of the elderly, being watchful for unusual excretory habits, extra clothes, or the smell of elderly persons’ dirty clothing.
Ethical Dilemma Factor in Regarding Physical Restraints to Elderly of Female Nurses with the Living Together Experience  [PDF]
Miwa Yamamoto, Shizue Mizuno, Masako Aota
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.35064
Abstract: Purpose: The aim of this study was to illuminate the connotation of “dilemma” regarding the use of physical restraint on elderly patients as represented by female nurses working in general wards at community hospitals who also live with elderly adults at home. Method: The study used the questionnaire method with an independently prepared questionnaire. Participants: The objective of the study was explained to the persons in charge of nursing in the selected 17 hospitals, and 1929. Finally, this study of participants were 524 female nurses working in general 54 wards (excluding the emergency wards of psychiatry, pediatrics, obstetrics, outpatients, operating rooms, and intensive care units) at community hospitals who also live with elderly adults at home. Results and conclusions: Cronbach’s overall coefficient for the 20 items of dilemma was high (0.78) and the factor analysis extracted four dilemma factors as having a characteristic value of 1 (Kaiser-Meyer-Olkin measure value = 0.81) with a cumulative contribution ratio of 64.5%. The high Cronbach’s for these items (0.86, 0.88, 0.87 and 0.81) confirmed the internal consistencies. With respect to the dilemma where nurses working in general wards at community hospitals who also live with elderly adults at home are faced with the physical restraint of elderly persons, four factors in the clarification of the dilemma were extracted: accomplishment of medical-treatment and accident prevention, characteristic features in nursing for elderly patients with dementia, healthcare professional relationship in nursing for elderly patients with dementia, and priorities on the accident prevention for elderly patients with dementia. Therefore, the construction of four systems to cope with these dilemmas is suggested. These systems would enable practising nurses to: (i) institution of policies to encourage discussion between nurses and other medical staff to reach consensus on treatment; (ii) allocating elderly care specialists to wards to promote alternatives to restraints; (iii) establishment of safety standards to define nurses’ responsibilities; and (iv) institution of continuous ethical education for nurses.

Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.32027

Purpose: This study aimed to develop an ethical dilemma scale for nurses faced with the use of physical restraint when caring for elderly patients with dementia. Methods: We used a previously established 20-item dilemma scale. The objective and method of the study were explained to the head of nursing at 17 selected hospitals, and 121 nurses working in the general wards of 14 hospitals (excluding emergency department wards of psychiatry, pediatrics, obstetrics, outpatients, operating rooms and intensive care units) who agreed to participate were enrolled in 2000. Seventy-six nurses from one of the hospitals were selected after eight years (2008) to provide a comparison. Ethical considerations: The study was conducted with the approval of the ethics committee at Meiji University of Integrative Medicine. Results and discussion: Four factors were compared between 2000 and 2008: “execution of treatment and security”, “characteristic features in nursing of elderly patients with dementia”, “cooperative relationship in nursing”, and “priorities in nursing”. The cumulative contribution ratio was 65.3% (KMO = 0.77, p = 0.000) in 2000 and 72.5% (KMO = 0.78, p = 0.000) in 2008. Therefore, the scale dilemma nurse faced physical restraints to elderly patients with dementia in Japan was developed 4 facoters from 17-delremmas items of 20 items.

Survey on the Use of Information and Communication Technology Tools in Educating Caregivers of Elderly People with Dementia —Analysis from Ichushi and PubMed  [PDF]
Miwa Yamamoto, Noriko Adachi, Yasuko Maekawa, Tomoharu Nakashima, Shigeru Sakuraba
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.45043

This study aimed to clarify the use of computer simulations in educating caregivers of elderly people with dementia. Thesaurus words in articles indexed in Ichushi and PubMed were analyzed using commercially available “Trend Search” text-mining software developed by FUJITSU. The analysis maps relational words in the articles, with line size and distance between words showing the strength of the relation. For ethical purposes, articles were anonymized for analysis. The search was conducted using the query phrases “elderly people with dementia AND simulation”, and retrieved four articles from Ichushi (2007-2010) and 16 from PubMed (1992-2012). The search results revealed that little research has been done on this subject, and highlighted opportunities to further investigate the use of ICT tools in educating caregivers of elderly people with dementia.

Molecules , 2013, DOI: 10.3390/molecules18055163
Abstract: To examine the effects of weak intermolecular interactions on solid-phase extraction (SPE) and chromatographic separation, we synthesized some novel stationary phases with a heavy atom effect layer by immobilizing halogenated aromatic rings and hydroxyl groups onto the surface of a hydrophilic base polymer. Using SPE cartridges packed with the functionalized materials, we found that the heavy atom stationary phases could selectively retain halophenols in organic solvents, such as 1-propanol which blocks the hydrogen bonding, or acetonitrile which blocks the p-p interaction. The extraction efficiency of the materials toward the halophenols depended on the dipole moments of phenoxy groups present as functional groups. On the other hand, the extraction efficiency of solutes toward the functional group depended on their molar refractions, i.e., induced dipole moments. The retention of the solutes to the stationary phase ultimately depended on not only strong intermolecular interactions, but also the effects of weak interactions such as the dispersion force.
