Background: In Japan, new challenges are emerging, such as declining birth rates, an increase in age at childbirth, postpartum depression, and child abuse. Methods: This study examines the factors influencing maternal consultation behavior at public institutions using some of the data from the Japan COVID-19 and Society Internet Survey (JACSIS). A total of 6227 women (1380 pregnant and 4847 postpartum) were analyzed through logistic regression. Results: The results showed different factors influencing consultations between pregnant women and postpartum women. Among pregnant women, different trends were observed between primigravidae and multigravidae, indicating that primigravidae aged ≥40 years and multigravidae with multiple childbirths tend to seek consultations more frequently. In postpartum women, psychological distress (K6), adverse childhood experiences (ACEs), and social support networks significantly influenced consultation behavior. Postpartum women with extensive support networks (≥3 confidants) exhibited higher consultation rates. In contrast, those with elevated Edinburgh Postnatal Depression Scale (EPDS) and Mother-to-Infant Bonding Scale (MIBS-J) scores were less likely to seek help, potentially due to mental health stigma. Conclusions: This study showed that pregnant and postpartum women facing physical, mental, family, or relationship issues are seeking consultations and receiving thorough support. On the other hand, since some pregnant and postpartum women refrained from seeking consultation, it is necessary to further consider support measures that make it easier for all pregnant and postpartum women to seek advice in the future.

金栄山妙成寺（石川県羽咋市）は、北陸における日蓮宗本山であり、加賀藩前田家の菩提寺のひとつである。本論文は、妙成寺書院にともなう庭園について3次元測量と直接計測、一部の試掘調査をおこない、庭園の地割と意匠の客観的な把握に努め、空間と景観構成の特色の把握を目的とした。研究の結果、庭園の地割としては、（1）平地、（2）池泉、（3）鶴石組、（4）亀石組、（5）斜面、の大きく5つによって構成されていた。さらに、鶴と亀の祝儀の庭を基本としつつ、祖師堂と五重塔を大胆に庭園に取り込んだ主要伽藍の借景に特徴が認められ、池泉東岸正面の平石と寿福院墓とが一直線上に並ぶという、興味深い空間と景観の構成を有していることが分かった。

In Bingo Bridge which is the suspended bridge in Nara Prefecture, fracture of hanger rod was found in 2015. Furthermore, in this bridge, the surface corrosion of main cable and stiffening girders were also observed. This bridge was closed to traffic until all the hanger rods replaced to the hanger ropes. Therefore, to inspect the corrosion of main cable and the stiffening truss during the road closure, the high sensitivity magnetic nondestructive testing was applied. Additionally, one of the purpose of this research is to investigate the application of high sensitivity magnetic nondestructive testing on site.

Tooth loss may be a modifiable risk factor for memory disorders, but the causal relationship has not been evaluated sufficiently. This 5-year prospective cohort study investigated the effect of tooth loss on the development of mild memory impairment (MMI) among the elderly. Data are from the baseline and follow-up examinations of 2,335 community residents who were cognitively intact at baseline. The number of remaining teeth at baseline was classified as zero, 1-8, 9-16, 17-24, and 25-32. The main outcome for the analysis was the development of MMI at follow-up. After adjustment for potential confounding factors in multivariable logistic regression analysis, the odds ratio of per 1 tooth loss at baseline was 1.02 (95% confidence interval, 1.00-1.03). The odds ratio of edentulism for MMI was 2.39 (1.48-3.86) compared to 25-32 teeth. The odds ratio of becoming edentulous compared to retaining 1-8 teeth in the 1-8 teeth group at baseline was 4.68 (1.50-14.58). Tooth loss predicts the development of MMI among the elderly.

本研究では、岩手県気仙郡住田町の3か所の応急仮設住宅団地を対象に、団地で実施されているコミュニティ支援活動の実態と、入居者のコミュニティ活動の状況や活動への評価を明らかにすることを目的とした。研究方法は、仮設支援協議会の各組織が実施している活動の日誌の分析と、入居者を対象としたアンケート調査分析である。研究の結論は次の通りである。まずコミュニティ支援活動は、多数の組織の連携により実施され、目的や支援組織のかかわりかたで9つに分類できた。その活動の傾向は時期によって変化している。活動に参加した程度は年齢によって差がみられた。仮設団地でのコミュニティ支援活動は住民から一定の評価を得ており、住民同士や支援者との交流機会の提供とともに、住民に気分転換等の精神的な効果を与えていた。

From the view point of relationship with space composition and the usage of space, this paper aims at evaluating the space function of the welfare home reused a wooden house. This house satisfies the scale requirement for the welfare home to be the large one-story house of floorage 228 m2. The composition of rooms connected in the veranda corridor should make the use change of the space by the slight improvement possible with securing the independence of the room. It is pointed out as the terms of building that realized the space composition as the welfare home. The act in veranda space to look at the Japanese garden is induced by the improvement design that leaves the atmosphere of tradition house, and the point that can become the home feeling the dearness of wooden house for the old people is important. It is the part left as the subject of improvement plan about securing of the homogeneous heat environment of the building, the dispersion of the office work space and the shortage of the passage width. These are spatial terms of restriction of the use change by the improvement of existent building if the existence of the upper limit of improvement cost is taken into consideration.

A phase transition of perfect crystal of α-quartz-type GeO_2 was found to be 6.0 GPa at 300 K. It was also shown a large volume shrinkage of approximately 12 % due to phase transition. Phase transition pressure of α-quartz-type GeO_2 crystal contained vacancies was decreased with increased of density of vacancies. In case of phase transition of GeO_2 crystal contained dislocation, phase transition was estimated to be 3.7 GPa.
