Advances in Applied Sociology (AASoci) , 2015, DOI: 10.4236/aasoci.2015.51004
Abstract: Aim: We aimed to explore factors related to improving health-related quality of life (HRQOL) among Japanese community-residing elderly individuals. Using a questionnaire, we investigated subjective satisfaction with verbal communication, dental status, and HRQOL in community-residing elderly people. Methods: Subjects were 454 independent elderly individuals, with a mean age of 76.1 ± 6.8 years, living in Japan. The Japanese version of the SF-8 Health Survey was used to evaluate HRQOL. Subjective satisfaction with verbal communication was investigated using a five-point scale. Multiple regression analysis was conducted to identify determinants affecting HRQOL. Covariance structure analysis was conducted to investigate any mutual association between age, presence of natural teeth, satisfaction with verbal communication, and HRQOL. Results: The HRQOL scores of subjects who answered that they were “very satisfied” or “satisfied” with verbal communication were significantly higher than those of subjects in the groups of “neither satisfied nor unsatisfied”, the “unsatisfied”, and the “very unsatisfied” in physical component summary (PCS) scores or mental component summary (MCS) scores of SF-8 (P < 0.001). In multiple regression analysis, age, gender, and satisfaction with verbal communication were independent predictors of PCS scores. Furthermore, age and subjective satisfaction with verbal communication were also independent predictors of MCS scores. There was a significant positive correlation between subjective satisfaction with verbal communication and PCS (r = 0.307, P < 0.001) or MCS (r = 0.435, P < 0.001) in covariance structure analysis. Conclusions: Satisfaction with verbal communication is significantly related to HRQOL among Japanese community-dwelling elderly individuals.

ISRN Geriatrics , 2013, DOI: 10.1155/2013/194693
Abstract: The purpose of the present study was to develop a new assessment scale to evaluate masticatory ability among community-dwelling elderly individuals. The study comprised 761 independent elderly subjects residing in the community. We pooled 25 food items with various textures. Based upon the pass rate and nonresponse rate, we extracted 9 food items to be included in the masticatory ability assessment for the community-dwelling elderly (MACE). The reliability of this assessment was determined using Cronbach’s alpha coefficients. We then examined the concurrent validity of the MACE by comparing it with an existing method termed “mastication score.” Additionally, the convergent validity was examined by comparing the correlation coefficients of MACE, general oral health assessment index (GOHAI), and the number of teeth. Cronbach’s alpha coefficient of MACE was 0.89 ( ), indicating satisfactory reliability. MACE was significantly correlated with the mastication score ( ), GOHAI ( ), and the number of teeth ( ). These results suggest that MACE is a useful tool with sufficient reliability and validity to identify declines in masticatory ability among community-dwelling elderly individuals. 1. Introduction It is very important for middle-aged and elderly individuals in particular to maintain a healthy diet. Furthermore, for community-dwelling elderly persons, dietary insufficiency is adversely associated with overall health status [1, 2]. The digestive process begins with mastication, which is influenced by oral health status [3, 4]. Some cross-sectional studies report that chewing function is related to nutritional status, food selection, body composition (sarcopenia), and physical balance [5, 6]. In particular, poor mastication may contribute to restricted fruit and vegetable intake [7, 8]. The National Health and Nutrition Examination Survey of Japan indicated that 26.6% of Japanese people aged 60–69 years and 40.8% of Japanese people above 70 years of age had difficulty chewing [9] Interestingly, Bradbury et al. reported that the combined approach of improved masticatory ability and provision of suitable nutritional guidance was effective in increasing fruit and vegetable intake among the elderly [10]. Improvement of masticatory status has been stated as a part of the Food and Nutrition Education (Shokuiku) by the Cabinet of Japan [11]. However, few assessments on the masticatory status of community-dwelling elderly individuals have been reported. In many epidemiological studies among community-dwelling elderly persons, subjective evaluation has frequently
Acute Stress Symptoms in Families of Patients Admitted to the Intensive Care Unit during the First 24 Hours Following Admission in Japan  [PDF]

Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.54035
Abstract: Families of patients in the intensive care unit often experience sever stress. Understanding their experience is important for providing family-centered care during this difficult period. Little is known about the experience of families of patients admitted to the intensive care unit (ICU). To evaluate the prevalence and factors associated with acute stress symptoms among families of patients admitted to the ICU, we carried out a cross-sectional study at a teaching and advanced treatment hospital. The mean total Impact of Event Scale-Revised (IES-R) score differed significantly between planned and unplanned ICU admissions (t = 4.03, p < 0.05), indicating a main effect of admission type (F = 18.5, p < 0.05). There was no significant main effect of relationship (F = 0.05, p = 0.82) or interaction effect of admission type and relationship (F = 0.54, p = 0.47). Multiple regression analysis indicated that admission type was significantly associated with acute stress symptoms (B = 18.09, β = 0.47, p < 0.01), and explained 22% of the variance in total IES-R score. Whether a patient had a planned or unplanned admission to the ICU influenced symptoms associated with acute stress symptoms of family members more than did getting support from nurses, being the patient’s spouse, or the severity of illness of the patient.
Evaluating Sleeping and Waking States of Infants: Consistency of Actigraph and Observational Data  [PDF]
Rie Nakamura Ikeda, Kiyoko Fukai
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.65053
Abstract: The objective was to evaluate sleeping and waking states of infants <6 months old. The design of study was comparing video-recorded and actigraphic data. Participants were thirteen healthy 3- to 5-month-old infants. At their homes, subjects wore an ankle actigraph for 1 h and were videotaped simultaneously. We performed per-minute analysis of video data using the method for observing newborns developed by Brazelton. Video and actigraphic data were compared each minute. The total concordance rate was 93.5%. Sleep/wake identification by actigraphy and visual observation correspond closely for infants.
The Experience of Postpartum Depression among Mothers with Withdrawn Attachment Style during Pregnancy and the First Postnatal Month  [PDF]

Open Journal of Depression (OJD) , 2015, DOI: 10.4236/ojd.2015.44008
Abstract: Approximately 19% of women experience minor or major depression in the first three months following childbirth. Most research suggests that women with withdrawn attachment styles are less likely to be depressed. However, unlike mothers in Western culture, mothers in Japan with withdrawn attachment styles are reported to have greater potential to become depressed. Thus, the aim of this study was to describe the behaviors and situational awareness of Japanese mothers’ with withdrawn attachment styles during pregnancy in order to reveal the specific dynamics underlying the withdrawn style. Interview data were analyzed using qualitative thematic content analysis. Of the 84 women assessed, 12 were determined to have a withdrawn style, and based on the Mini-International Neuropsychiatric Interview, five demonstrated the onset of postpartum depression (PPD). Two themes regarding relationships with partners emerged including: 1) confiding behavior: the importance of what is shared; and 2) need to be heard: wanting sympathy rather than criticism. Additionally, three themes describing mothers’ experiences during the first postnatal month emerged: 1) overwhelming experiences: the childbirth experience; 2) seeking help: behavior changes altered relationships; and 3) experience with the baby. Withdrawn style mothers keep distance from crisis, avoid closeness with others, and opt to manage problems by themselves. However, childbirth and infant care are not easily managed in this style. Mothers who used childbirth to confide in their partners may have reduced the severity of insecurity or developed a more secure style. Healthcare professionals are in the best position to develop good relationships with new mothers and provide support that focuses more on emotional factors and self-esteem levels.

Abstract: The number of deaths caused by child abuse is increasing, which is one of social concerns. The mental health of mothers might be related to child abuse. The aim of this study was to examine and compare the mental state of mothers in both the antepartum and postpartum period assessed by the Edinburgh Postnatal Depression Scale (EPDS) and Mother-Infant-Bonding-Scale (MIBS), and compare the results. Participants (n = 134) were recruited twice in antepartum medical checkups (20 to 36 weeks of gestation) and postpartum medical checkups (1 month after birth). Information on characteristics of participants was collected from medical records in both periods. Family function and ante-postpartum mental health were assessed by Family APGAR, EPDS, and MIBS. Antepartum depressive state was related to postpartum depressive state (p = 0.015), antepartum bonding was related to bonding in postpartum bonding (p = 0.0001), and antepartum bonding disorder was related to postpartum depressive state (relative risk = 11.7). Worries about costs and poor of family function were related to the mental health of mothers in both the antepartum and postpartum periods. Antepartum depressive state is an indicator of postpartum depression. We suggested that health professionals conduct an evaluation of mother’s mental health and related factors in the antepartum period. The present findings emphasize the importance of antepartum mental health as a predictor of postpartum depression and bonding disorder.
Toward an Understanding of the Madden-Julian Oscillation: With a Mesoscale-Convection-Resolving Model of 0.2 Degree Grid
Masanori Yamasaki
Advances in Meteorology , 2011, DOI: 10.1155/2011/296914
Abstract: This paper describes results from numerical experiments which have been performed as the author's first step toward a better understanding of the Madden-Julian oscillation (MJO). This study uses the author's mesoscale-convection-resolving model that was developed in the 1980s to improve parametrization schemes of moist convection. Results from numerical experiments by changing the SST anomaly in the warm pool area indicate that the period of the MJO does not monotonously change with increasing SST anomaly. Between the two extreme cases (no anomaly and strong anomaly), there is a regime in which the period varies in a wide range from 20 to 60 days. In the case of no warm pool, eastward-propagating Kelvin waves are dominant, whereas in the case of a strong warm pool, it produces a quasi-stationary convective system (with pronounced time variation). In a certain regime between the two extreme cases, convective activities with two different properties are strongly interacted, and the period of oscillations becomes complicated. The properties and behaviors of large-scale convective system (LCS), synoptic-scale convective system (SCS), mesoscale convective system (MCS), and mesoscale convection (MC), which constitute the hierarchical structure of the MJO, are also examined. It is also shown that cloud clusters, which constitute the SCS (such as super cloud cluster SCC), consist of a few MCS, and a new MCS forms to the west of the existing MCS. The northwesterly and southwesterly low-level flows contribute to this feature. In view of recent emphasis of the importance of the relative humidity above the boundary layer, it is shown that the model can simulate convective processes that moisten the atmosphere, and the importance of latent instability (positive CAPE), which is a necessary condition for the wave-CISK, is emphasized.
The films of Mitani Kōki: Intertextuality and comedy in contemporary Japanese cinema
Rie Yamasaki
New Voices : A Journal for Emerging Scholars of Japanese Studies in Australia and New Zealand , 2011,
Abstract: The purpose of this article is to investigate the importance of intertextual references in the films of one of Japan’s most successful contemporary comedy filmmakers, Mitani Kōki. Since Mitani consciously makes references to other films, intertextuality works as a key element to comprehend his works. Although the recognition of the references used in his films is not too significant to influence entertaining perspectives, the absence of these detailed intertextual components would prevent the films being recognised as ‘Mitani films’.By analysing all of his four films, this article will provide a useful example of the idea of intertextuality. In addition, this study will also focus on Japan in the 1990s, when Mitani debuted as a film director. This is an important point to be discussed, since his film-making approaches seem to be significantly related to the social background of the time.

Introduction This paper describes results from a study which is made as the author’s first step toward a better understanding of the Madden-Julian oscillation (MJO) with a mesocale-convection-resolving model. As is well known, the MJO was discovered in the early 1970s by Madden and Julian [1, 2], and its understanding has been advanced by a number of observational, theoretical and numerical studies in these 40 years. The author intends to better understand the following three problems at the early phase in a series of his studies. The first is the period (or time scale) of the MJO. The period was first identified as 40–50 day by Madden and Julian [1, 2]. In the 1980s, a period of 30–50 day was preferably used by Krishnamurti and
Arithmetical properties of Multiple Ramanujan sums
Yoshinori Yamasaki
Mathematics , 2007, DOI: 10.1007/s11139-010-9223-8
Abstract: In the present paper, we introduce a multiple Ramanujan sum for arithmetic functions, which gives a multivariable extension of the generalized Ramanujan sum studied by D. R. Anderson and T. M. Apostol. We then find fundamental arithmetic properties of the multiple Ramanujan sum and study several types of Dirichlet series involving the multiple Ramanujan sum. As an application, we evaluate higher-dimensional determinants of higher-dimensional matrices, the entries of which are given by values of the multiple Ramanujan sum.
