Synthesis and Spectroscopic Properties of Ferrocenyl Derivative Containing Donor and Acceptor Groups  [PDF]
Makoto Minato, Chiharu Sorai, Takashi Ito, Masashi Kiguchi, Midori Kato
International Journal of Organic Chemistry (IJOC) , 2017, DOI: 10.4236/ijoc.2017.73022
Abstract: Much interest has been devoted to organometallic NLO materials. We have become interested in exploring the utility of ferrocenyl group as the conjugating bridge. Thus, we synthesized 1-{{[1,3-(5-methylbenzo)dithiol]-2-yli- dene}methyl}-1’-[2-(p-nitrophenyl)-(E)-ethenyl]ferrocene (1). This new ferrocenyl compound has a donor and an acceptor group in 1,1’-positions. Investigations of the solvatochromic property of the compound revealed that it has polarized structure in a polar solvent, such as DMF. SHG efficiency of the compound was estimated by an SHEW (second-harmonic generation with the evanescent wave) method.
Growth patterns in Onychophora (velvet worms): lack of a localised posterior proliferation zone
Georg Mayer, Chiharu Kato, Bj?rn Quast, Rebecca H Chisholm, Kerry A Landman, Leonie M Quinn
BMC Evolutionary Biology , 2010, DOI: 10.1186/1471-2148-10-339
Abstract: Using in vivo incorporation of the DNA replication marker BrdU (5-bromo-2'-deoxyuridine) and anti-phospho-histone H3 immunolabelling, we found that a localised posterior region of proliferating cells does not occur at any developmental stage in onychophoran embryos. This contrasts with a localised pattern of cell divisions at the posterior end of annelid embryos, which we used as a positive control. Based on our data, we present a mathematical model, which challenges the paradigm that a localised posterior proliferation zone is necessary for segment patterning in short germ developing arthropods.Our findings suggest that a posterior proliferation zone was absent in the last common ancestor of Onychophora and Arthropoda. By comparing our data from Onychophora with those from annelids, arthropods, and chordates, we suggest that the occurrence of a "posterior growth zone" currently cannot be used to support the homology of segmentation between these three animal groups.The most obvious subdivision of the body into serially repeated units or segments occurs in annelids (ringed worms), panarthropods (onychophorans, tardigrades and arthropods), and chordates (including vertebrates, urochordates and cephalochordates). During embryonic development, segments are commonly believed to originate from the so-called "posterior growth zone" (review [1]). However, this term has been applied very broadly in the past, which has resulted in ambiguity. For example, the occurrence of a "posterior growth zone" has been used to support the homology of segmentation either specifically in annelids and panarthropods [2-4] or in all three groups of segmented animals, suggesting that segmentation was present in their last common ancestor [1,5-8].Traditionally, the term "posterior growth zone" has been used to describe a localised and highly proliferative terminal body region, which has been dubbed the "proliferating area" or "zone of proliferation" [9-11]. While it seems clear that such a loca

Abstract:

This report attempts to ascertain the current state of, and outstanding issues relating to, nursing diagnosis, as taught in nursing education in Japan, and to obtain basic resources that will allow the improvement of said nursing diagnosis training. A self-completed, anonymous survey was carried out in regard to teaching staff responsible for classes in “nursing process” or “nursing diagnosis” at 183 university institutions involved in nursing education nationwide. Responses were received from 82 people, which clarified the following three points. 1) Of the 63 universities teaching nursing process as an independent subject, approximately 62% included nursing diagnosis. 2) A diverse range of educational materials were used in nursing diagnosis training, including NANDA-I nursing diagnosis. 3) In implementing nursing process using nursing diagnosis, issues raised included the following: the limitations of education “on paper”, using theoretical patients, insufficient skills among teaching staff, the difficulty of realizing practical training in a clinical setting, and the tendency to try to make a simple diagnosis fit the circumstances. In the future, this study suggests that it may be important to create a set of guidelines guaranteeing a minimum level of educational content in relation to nursing diagnosis, which must be learned before graduation.

Role Expectation of Nurse Managers in Geriatric Health Services Facilities  [PDF]
Chiharu Miyata, Hidenori Arai
Advances in Aging Research (AAR) , 2016, DOI: 10.4236/aar.2016.55012
Abstract:
Back ground: The characteristics of geriatric health services facilities (GHSF) in Japan include provision of care focused on the life of the residents, and there is a need for cooperation between care workers and physical therapists responsible for the care. Thus, it is expected that a nurse manager occupies specific roles suited for the above characteristics that are different from those of medical facilities. Thus, we aimed to clarify the role expected of nurse managers via a questionnaire survey administered to nurses and care workers in GHSF. Methods: We used a descriptive, cross-sectional design. The study was conducted in 56 GHSF all over Japan. The instrument used for data collection was a questionnaire. The questionnaires consisted of 35 items for determining role expectation of nurse managers, the background information of respondents. The role of nurse managers was analyzed using principal factor analysis (promax rotation). Findings: A total of 259 nurses and care workers participated in this study. We extracted 34 items by factor analysis, which were classified into three factors (promotion of home nursing, management of medical care, and environment creation for collaboration and education). Among care workers, four factors consisting of 33 items were extracted. Factors one, two, and three were similar to those of nurses; “intervention to ethical problem” was extracted as the additional fourth factor. Conclusion: The roles required for nurse managers in GHSF are the promotion of home nursing, which is the original role of the health services facilities, exhibition of the specialty as a healthcare professional, creation of a work environment that promotes mutual understanding for collaboration with other professionals, and enhancement of the education and training system.

Perception gaps for recognition behavior between staff nurses and their managers  [PDF]
Chiharu Miyata, Hidenori Arai, Sawako Suga
Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.37066
Abstract: Nurse managers play a critical role in improving the work environment. Important leadership characteristics for nurse managers include visibility, accessibility, communication, recognition, and support. The nurse manager’s recognition behaviors strongly influence the job satisfaction of staff nurses. In our previous study, we investigated how staff nurses perceived the nurse manager’s recognition behaviors and revealed that there was a divergence in practical approaches to these behaviors between the nurse manager and the staff. We assume that one factor causing this divergence could be perception gaps between the nurse manager and the staff. The aim of this study, therefore, was to uncover what types of perception gaps exist between the nurse manager and staff nurses and whether the background of staff nurses, such as years of experience or academic background, could affect the staff nurses’ perceptions. This quantitative, cross-sectional study involved 10 hospitals in Japan. A total of 1425 nurses completed the questionnaire. The results showed that staff nurses considered “Respect job schedule preferences” to be the most important of the recognition behaviors. In contrast, nurse managers gave “Nurse manager meets with the staff nurses to discuss patient care and unit management” the highest score for importance. Four factors (marriage status, age, years of clinical experience, and training background) affected the professional awareness of recognition behaviors. Our results suggest that nurse managers need to consider these factors when they conduct recognition behaviors.
Nurse manager’s recognition behavior with staff nurses in Japan-based on semi-structured interviews  [PDF]
Chiharu Miyata, Hidenori Arai, Sawako Suga
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41001
Abstract:

Objective: The purpose of this qualitative study was to obtain a better understanding of nurse manager’s recognition behavior. Methods: This study, consisting of semi-structured interviews, was conducted in five hospitals with 100 beds or more in the Kanto, Kansai, and Kyushu regions of Japan. Fifteen nurse managers, who each had more than one year of professional work experience as a nurse manager, participated in this study. Results: We extracted four categories and fourteen subcategories as the factors related to the recognition behaviors in nurse managers. The first category is the basis of the recognition behaviors, which were divided into the following four subcategories: recognition behaviors that they received, perception of recognition behaviors, construction of confidential relationships with staff nurses, and the organizational climate. The second category is the issues that make recognition behaviors difficult, which were classified into the following three subcategories: multiple duties, number of staff nurses, and characteristics of the recent staff nurses. The third category is the factors regarding the staff nurses that must be considered, which consist of the following two subcategories: the characteristics and motivation of staff nurses and recognition behaviors that the staff nurses expect. The forth category is the methods of the recognition behaviors, which consist of the following five categories: watching over and consideration of individuals, evaluation of routine work, development as a professional, opinion sharing and delegating work, and promotion of work-life balance. Conclusions: The recognition behavior by nurse managers is influenced by their own experience, and nurse managers practice recognition behaviors in response to the characteristics of their staff nurses in a busy environment. Our results suggest that nurse managers need expertise in management for them to identity appropriate recognition behavior.

Yield Prediction of Sugar Beet through Combined Use of Satellite Data and Meteorological Data

Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n4p251
Abstract: This study was carried out for the following two purposes through analysis of satellite data and meteorological data. One is to assess the feasibility of developing an efficient cultivation support system for effective reduction of costs relating to sugar beet cultivation. The other is to predict the root yield before the harvesting season. The cumulative temperature, cumulative precipitation and cumulative solar radiation from the end of April to the middle of July were selected as the predictors of the root yield prediction formula. The predictive error was 3.8t/ha, that was a result calculated by the farmers group, after weighted to the predicted root yield using NDVI. The results suggest that it is possible to predict the root yield before three months of the harvesting season. For providing such results to sugar companies in much earlier before the harvesting, the efficiency of sugar beet collection and sugar production will increase substantially.

Chiharu Miyata, Hidenori Arai
Advances in Aging Research (AAR) , 2019, DOI: 10.4236/aar.2019.86010
Abstract: Background: The characteristics of geriatric health services facilities (GHSFs) in Japan include provision of care focused on the life of the residents, and there is a need for cooperation between care workers and physical therapists responsible for the care. Our goal is to create an organizational system that allows nurses to succeed professionally. To do this, we must first discuss the professional behavior of nurses in GHSFs. Objectives: The aim of the present study was to clarify the professional behavior of nurses in GHSFs using a questionnaire survey. Method: We used a descriptive, cross-sectional design. The study was conducted in 1000 GHSFs all over Japan. The instrument used for data collection was a questionnaire. The questionnaires consisted of 24 items for determining the professional behavior of nurses, the background information of respondents. The professional behavior of nurses was analyzed using principal factor analysis (Promax rotation). Results: A total of 1189 nurses participated. Of those, 91% (n = 1084) were women, and mean age was 48.2 years. Most participants were staff nurses (n = 791; 66%). We extracted 16 items by factor analysis, which were classified into four factors (professional development, autonomy, positive assertiveness to colleagues, and advocating for patient). Conclusion: The professional behaviors as identified in this study are similar to those reported in previous studies of clinical nurses in hospital. However, some subscale results are specific to the characteristics of GHSFs. The ability to understand professional behaviors has significant implications in terms of affirming and identifying sources of quality of care and creating a professional practice environment within GHSFs.

Journal of Information Security (JIS) , 2017, DOI: 10.4236/jis.2017.81005
Abstract: While search engines have become vital tools for searching information on the Internet, privacy issues remain a growing concern due to the technological abilities of search engines to retain user search logs. Although such capabilities might provide enhanced personalized search results, the confidentiality of user intent remains uncertain. Even with web search query obfuscation techniques, another challenge remains, namely, reusing the same obfuscation methods is problematic, given that search engines have enormous computation and storage resources for query disambiguation. A number of web search query privacy procedures involve the cooperation of the search engine, a non-trusted entity in such cases, making query obfuscation even more challenging. In this study, we provide a review on how search engines work in regards to web search queries and user intent. Secondly, this study reviews material in a manner accessible to those outside computer science with the intent to introduce knowledge of web search engines to enable non-computer scientists to approach web search query privacy innovatively. As a contribution, we identify and highlight areas open for further investigative and innovative research in regards to end-user personalized web search privacy—that is methods that can be executed on the user side without third party involvement such as, search engines. The goal is to motivate future web search obfuscation heuristics that give users control over their personal search privacy.
