The purpose of this paper is to identify the significance and challenges of government infertility support from the perspective of nursing professionals involved in government infertility support and infertile women.
This dissertation consists of three chapters. First, in Chapter 1, as a research perspective on the current situation surrounding infertility and administrative infertility support, a review of the literature on “psychological characteristics and coping with infertility,” “infertility support,” and “administrative infertility support centered on infertility consultation centers” was conducted in particular to focus the issues and analysis perspective of this study. Chapter 2, Section 1 clarified the significance of administrative infertility support as perceived by nurses involved in infertility support at infertility consultation centers. In Chapter 2, Section 2, a study of infertile women was conducted to clarify the current situation and the relationship between infertile women's perceptions and use of administrative infertility support. Chapter 3 reviews the findings on the significance and challenges of administrative infertility support based on the perspectives of nursing professionals and infertile women, discusses the
significance and challenges of administrative infertility support, and presents the conclusions and limitations of this study and future challenges.
From the perspective of nursing professionals, the significance of administrative infertility support was found to be threefold: [it can supplement infertility support provided by medical institutions], [it can provide psychological support], and [it can provide a wide range of infertility-related counseling]. However, only 31.1% of infertile women were aware of government infertility support, and only 16.3% of infertile women had used it. Thus, although the recognition and utilization rates of government infertility
support are low, the level of satisfaction with government infertility support is high, indicating that it is an effective form of support. In addition, 67.5% of those who received infertility support from both medical institutions and the government rated the support as more effective than using only one of the two types of support.
Administrative infertility support, centered on specialized infertility consultation centers, has a different venue and function than medical institutions, and is significant in that it does not view infertility solely in terms of its medical meaning, but is able to attend to individual life concerns and choices. In addition, administrative infertility support has a well-developed support system that provides both information and knowledge for problem solving and emotional and psychological support in a well-balanced manner, which we believe leads to a sense of satisfaction for infertile women who use administrative infertility support.
As for the challenges of administrative infertility support, first of all, it is necessary for nurses and other professionals involved in administrative infertility support to improve the infertility support environment in each municipality and to improve their support skills. Then, the significance of administrative infertility support should be properly publicized and communicated to increase the awareness and use of administrative infertility support by infertile women. Furthermore, it was discussed that it is important to solve the issues of administrative infertility support through cooperation and collaboration between medical institutions and the government, as well as cooperation and collaboration among local governments.

Rheumatoid arthritis is a systemic inflammatory disease with chronic polyarthritis as the main symptom, and its treatment goal is to reduce disease activity as well as to suppress the progression of joint destruction. The purpose of this study is to investigate the ideal support for the home-based exercise therapy and also to clarify the current status of its implementation and the factors that cause its implementation.
Chapter 1 provides the background of this research, by discussing the symptoms and treatment of rheumatoid arthritis, the role of exercise therapy, the necessity of the home-based exercise therapy, and the support for patients with rheumatoid arthritis and other chronic diseases. Based on these findings, the purpose of this study was to clarify the current status of the home-based exercise therapy in patients with rheumatoid arthritis and the factors that implement it, and to examine the ideal way of support.
Chapter 2 describes a research study that clarifies the current status of the home-based exercise therapy for patients with rheumatoid arthritis. A questionnaire survey was conducted for rheumatoid arthritis patients living in one prefecture and the responses of 226 patients were analyzed. As a result, it was found that 35.4% of the patients knew that the home-based exercise therapy is recommended for patients with rheumatoid arthritis. On the other hand, 93.7% of patients thought that the home-based exercise therapy had a certain effect, and 91.4% of patients thought that the home-based exercise therapy was necessary. Thus, most patients had a high level of knowledge and interest in the home-based exercise therapy.
Chapter 3 describes a research study that clarifies the factors that affect the implementation of the home-based exercise therapy. A questionnaire survey was conducted for rheumatoid arthritis patients living in one prefecture and the answers obtained were divided into two groups, the group that underwent the home-based exercise therapy (n = 94) and the group that did not underwent it (n = 132). As a result of multivariate analysis, it was found that four factors significantly influenced the implementation of the home-based exercise therapy: age, occupation with a high degree of discretion, receiving injection treatment, and recommending the home-based exercise therapy by a doctor. It was also suggested that patients who were in pain or were not in remission were doing it according to their physical condition to the extent that it did not hurt.
Chapter 4 discusses the ideal way of support for the home-based exercise therapy by patients with rheumatoid arthritis. Based on the findings obtained in Chapters 2 and 3, the ideal way of support for the implementation of the home-based exercise therapy was discussed, focusing on three important perspectives: support for patient education, support for self-care, and support for multidisciplinary collaboration. Finally, based on the findings of this study, I concluded that it is important to provide support for patients with rheumatoid arthritis so that they can take the initiative in treating the home-based exercise therapy as an important way of self-care.

The utilization of post-retirement nurses, commonly referred to as second-career nurses (he reinafter SCNs), is being actively promoted. While SCNs are often said to bring a wealth of experience to nursing, concerns have been raised regarding their clinical competency and skills. However, currently, no concrete visualization or detailed examination exists of the nature of SCNs’ nursing practices, leaving such concerns unaddressed. Therefore, this study aimed to elucidate the specific aspects of excellence in the nursing practices of SCNs.
To clarify the excellence of SCNs, the study extracted specific elements of excellent nursing practices from previous research. These elements were conceptualized as the “Six Domains and 19 Components of Excellent Nursing.” Based on these concepts, a unique survey questionnaire was developed to measure perceptions of SCNs’ excellent nursing practices, which was employed to study two groups: second-career nurses (hereinafter referred to as the SCN group) and active nurses currently in practice (hereinafter referred to as the active group).
The SCN group included 84 participants, while the active group included 199 participants. Perceptions of excellent nursing practices among SCNs were analyzed as “excellence scores” for both groups. The results showed that in the active group, the average excellence scores tended to increase with age. Additionally, a factor analysis was performed to confirm whether the responses in the active group aligned with the conceptual framework. This analysis identified three factors: “Identity as a nursing professional,” “Excellent clinical practice competence,” and “Caring behaviors.”
A multiple comparison of the average total scores for the three factors across age groups revealed significant differences in “Excellent clinical practice competence” and “Caring behaviors” between the nurses in their 20s and 50s, as well as between those in their 30s and 50s. These findings suggest that age-related differences in how the active group perceived the excellence of SCNs may be attributed to varying levels of experience. Specifically, less experienced nurses may have difficulty focusing on others; consequently, they may not fully recognize the qualities of SCNs’ nursing practices. In contrast, nurses in their 40s and 50s, with greater experience, are more likely to engage in mutual interactions with SCNs, enabling them to observe and appreciate the visible aspects of SCNs’ excellent nursing practices.
The relationship between the excellence scores in the SCN group and external factors such as age, years of experience, experience as an SCN, pre-retirement position, current workplace, and employment format was analyzed. The results showed no significant differences in the excellence scores across any of these attributes. This lack of influence from external factors suggests that the exceptional nursing practices of SCNs are not externally imposed but are driven by intrinsic factors, such as a genuine interest in and passion for nursing, as well as a strong focus on others—factors rooted in SCNs’ “Identity as nursing professionals.”
Based on the above, the specific content of excellent nursing revealed in this study demonstrated by SCNs is threefold: nursing that makes visible “Excellent clinical practice competence,” “Caring behaviors,” and the intrinsic “Identity as a nursing professional” of second-career nurses. “Identity as a nursing professional” in SCNs reflects a deep-seated passion for nursing, characterized by a resolute dedication to the profession even after retirement. This identity is suggested to be shaped by the combination of their extensive nursing and life experiences, which results in an original approach to nursing, thus producing the excellence of SCNs.

This study aimed to clarify the food characteristics and functionality of Akamoku from various perspectives based on samples collected in Yamaguchi Prefecture. This study investigated changes in food characteristics and functionalities when Akamoku was processed, as well as the functionality of consuming commercially processed Akamoku products.
In the examination of food characteristics, we focused on the adhesiveness, adhesion, hardness, cohesiveness, and color differences of Akamoku due to differences in boiling conditions, drying methods, and rehydration temperature conditions. The results suggest that, in terms of boiling conditions, long boiling at 90°C for 3 or 5 min is not suitable from the viewpoints of properties and color. In terms of drying methods, viscosity was enhanced by freeze-drying and the green color was remarkably etained, suggesting that freeze-drying is useful for retaining the viscosity and color of Akamoku.
In the examination of changes in functionalities, we focused on changes in the antioxidative activity of Akamoku due to boiling conditions. Total polyphenol content and DPPH radical scavenging ability were determined using two types of Akamoku from different production areas, harvesting periods, and freezing conditions. The results showed that raw Akamoku of both types had higher polyphenol content and DPPH radical scavenging ability than processed Akamoku. Regarding the effect of boiling temperature on antioxidant properties, there was less variation in polyphenol content and antioxidative activity in the case of boiling at 60°C than in the case of boiling at 90°C, indicating that processing at lower temperatures may be effective in retaining antioxidative activity. Furthermore, a positive correlation was observed between the total polyphenol content and DPPH radical scavenging ability, suggesting that polyphenols play an important role in antioxidant properties.
Regarding the functionality of consuming commercial processed Akamoku products, we aimed to explore the effect of incorporating commercially available boiled Akamoku or microwave-boiled Akamoku into breakfast or lunch meals along with rice on postprandial blood glucose dynamics. The experiment included three distinct test meals: a standard meal comprising rice, soup, and seasoning; an Akamoku-enriched meal incorporating commercially available processed Akamoku with standard components; and a microwave-boiled Akamoku meal with standard meal components. The blood glucose dynamics under these three dietary conditions were compared between healthy adult male and female participants. The results suggested that both boiled Akamoku and microwave-boiled Akamoku reduced postprandial maximum blood glucose level, elevated blood glucose level, duration of elevated blood glucose level, and rate of elevated blood glucose level, but did not reduce blood glucose fall time and incremental area under the curve. These findings suggest that ingestion of Akamoku and heated Akamoku had an inhibitory effect on postprandial blood glucose elevation, but did not impede the bodily absorption of sugars or nutrients.
The findings of this study may increase our understanding of the food characteristics and functionality of Akamoku and promote its consumption. Furthermore, if the consumption of Akamoku expands, it is expected to contribute to the revitalization of local fisheries and fishing villages, as well as efforts to promote the sixth industrialization. Based on these results, future applications of Akamoku in the food industry are expected.

The promotion of early family reunification is required from the perspective ofensuring children's rights in children’s homes. Currently, family social workers areassigned to support the smooth reintegration of children into their families. In family reunification support, the development of social work based on high-level expertise is necessary. However, it cannot be said that the expertise required for implementing social work towards children’s family reunification is fully established. Therefore, this study aims to clarify the expertise of family social workers in deploying social work towards children’s family reunification.
Chapter 1 discusses the need to establish theories regarding the unique functions and methods of social work of family social workers by reviewing prior research and examining the current achievements and challenges faced in their support. Chapter 2 outlines the research objectives and defines key terms. Chapter 3 conducts interview research with family social workers to generate a hypothesis model regarding the factors and interrelations involved in deploying social work aimed at children’s family reunification. Chapter 4 conducts a survey using questionnaires targeting family social workers and examines the generated hypothesis model through covariance structure analysis, presenting insights into the expertise of family social workers' deployment of social work for children’s family reunification. Chapter 5 states the conclusion.
The deployment of social work by family social workers aimed at children's family reunification is shown to stem from a recognition that prioritizes the best interests of the child, expanding into specific support actions such as "assessment and planning," "support for children and parents," "collaboration inside and outside the facility," and "evaluation and discernment of family reunification." Particularly, "support for parents" and "collaboration with child consultation centers" were identified as areas of expertise in social work deployment. However, in examining the factors influencing the deployment of social work, the "evaluation and discernment of family reunification" is strongly influenced directly by the "awareness as a professional." This suggests that the expertise in the supportive actions of "support for parents" and "collaboration with child consultation centers" is not being sufficiently realized.
