We aimed to examine the psychometric properties of the second version of the Brief Evaluation of Psychosis Symptom Domains (BE-PSD-V2.0) and its correspondence with the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-Severity scale (CGI-S) scores. This cross-sectional study was conducted at 18 institutes in Japan. We performed correlational analyses to test the convergent and divergent validity of the BE-PSD-V2.0. Inter-rater reliability was assessed using intraclass correlation coefficients (ICCs). The equipercentile equating method was employed to examine the linking of the BE-PSD-V2.0 with the PANSS and the CGI-S. A total of 353 patients with schizophrenia spectrum disorders were included. Spearman's rank correlation coefficients between the BE-PSD-V2.0 item scores and their corresponding PANSS factor scores ranged from 0.64 to 0.86, indicating sufficient convergent validity. These specific correlation coefficients were consistently the highest among all item-to-factor comparisons, indicating sufficient divergent validity. In 34 patients, ICCs for the BE-PSD-V2.0 itemand total scores ranged from 0.60 to 0.94, showing sufficient inter-rater reliability. Conversion tables were established between the BE-PSD-V2.0 total score and the PANSS total score, between the BE-PSD-V2.0 total score and the CGI-S score, and between the BE-PSD-V2.0 item scores and their corresponding PANSS factor scores. A correspondence between symptomatic remission criteria using the PANSS and BE-PSD-V2.0 was confirmed. The BE-PSD-V2.0 possesses sufficient psychometric properties and corresponds to the PANSS and CGI-S. It is a sound and reliable brief rating scale for assessing symptoms in schizophrenia spectrum disorders, and its established conversion correspondences facilitate score interpretation within existing clinical paradigms for both clinical practice and research.

美容室では，洗い流すトリートメントの効果をより高めることを期待して，トリートメントを塗布した髪を手で揉み込む美容操作が行われている。このトリートメント揉み込み操作の効果を官能評価により確認したところ，髪のうねりが減少しシルエットのまとまりが向上した。このトリートメント揉み込み操作による毛髪のうねり減少効果の作用機序を明らかにするために，トリートメントにマーカーとして配合した塩基性赤51の染着挙動および毛髪内浸透域について検討し，さらに非ケラチンタンパク質凝集構造体の構造変化およびそれに伴う物性変化について検討した。その結果，トリートメントの揉み込み操作は，1）マーカーとして用いた塩基性赤51の染着量と浸透域を増加させた，2）毛髪を均一で柔軟な素材に変化させた，3）濡れた髪を真直ぐ整えながら乾かすブロー操作の際，非ケラチンタンパク質凝集構造体の再配列で生じる歪みを少なくし，均一な凝集構造体にしていた。トリートメントの揉み込み操作は，トリートメント成分の毛髪への浸透域を増加させながら毛髪の非ケラチンタンパク質凝集構造体を弛緩させ，髪を真直ぐに整えながら乾かす際に起こる繊維軸に沿った非ケラチンタンパク質構造体の均一な再配列を促進することで，髪のうねりを減少させたと考えられる。

The oxidative polymerization dyeing for wool fibers with pPDA/RC model solutions which formulated with the basic components of currently used cream-type oxidative hair dyes was investigated. The species of oxidized dye adsorbed within wool fibers dyed in pPDA/RC model solutions differ from the species in wool fibers dyed with solutions containing oxidative dyes generated by air oxidation in the pPDA/RC mixed solution, indicating that not all oxidative dyes produced in aqueous solutions are dyed. The ratio of oxidation dyes within wool fibers dyed in pPDA/RC model solutions varied slightly depending on the dyeing solution conditions, such as solution pH and pPDA/RC mixing ratio. In the case of the pPDA/RC (1:1) dyeing system, the dye species sorbed onto the fibers differs depending on the pH level of the dye bath. When dyed at pH 8, binuclear and trinuclear dyes, which are coupling dyes of pPDA and RC, adsorbs onto the fibers, whereas when dyed at pH 10, the absorption of trinuclear dye predominates and that of binuclear dye is not observed. These findings suggest that the trinuclear dye generated by the combination of pPDA and RC undergoes oxidative polymerization on the fiber surface and then penetrates into the fibers, unlike the mechanism of trinuclear dye formation in the pPDA alone system. Moreover, in dyeing systems where the mixture ratio of pPDA is higher than the mixture ratio of RC, it was found that the self-oxidative polymerization reaction of pPDA becomes predominant as the amount of pPDA increases and the binuclear and trinuclear dyes of pPDA coexist onto the fibers.

本研究では，反復接触時の室内背景画像の変化の有無が，画像人物の評価に及ぼす影響について検討した．具体的には，ある人物と毎回同じ場所で会うことで親近性が高まりやすく，その人物の評価が高まるのかどうか，それとも毎回異なる場所で会うことで，親近性に新奇性が付加され，評価が高まるのかを検討した．実験では，室内背景画像と人物画像を組み合わせて呈示し，人物画像の反復呈示ごとに異なる背景画像が呈示されるか，同一の背景画像が呈示されるかを操作した．実験1では，真顔人物を使用し，呈示回数を3回，6回，9回と操作した．実験2では，笑顔人物を使用し，呈示回数を3回，6回，9回，12回と操作した．その結果，背景が変化する場合の方が，少ない呈示回数で人物への好意度（好感度）の上昇が見られた．これは，反復呈示に伴う親近性の上昇に加え，背景変化による新奇性付加が，好意度（好感度）上昇に関わっているためだと考えられる．一方で安心感は，両条件において同じ呈示回数で上昇が見られ，背景情報の影響が及びにくいことが示された．

Good sleep is essential for a healthy life. While airflow improves sleep in a hot environment, it may cause an excessive drop in body temperature because thermal-adaptive behavior is inactive during sleep. This study aims to propose an airflow control theory that prevents the excessive drop in body temperature while maintaining good sleep. The theory changes the heat transfer coefficient between the skin and the environment by the intensity of the fan operation to maintain a heat loss of 30 W/m2 from a body with a skin temperature of 34.5 °C in a temperature-changing environment. We fabricated a ventilated sleep capsule in which this theory was embedded. Thermal manikin experiments were conducted to obtain the relationship between sensible heat transfer coefficients and the fan operating signal to establish control equations. We conducted a case study to evaluate whether the theory provided better sleep than sleeping with a regular fan running freely in homes in Ueda City, Japan, in one summer. Although the data used in the analysis were from only three subjects, the statistical analysis showed that sleeping in the ventilated sleep capsule provided better sleep, with a mean of 6% better sleep efficiency.

We focus on small-scale historical buildings, which play an important role as local resources, and propose an audio guide system designed to introduce these buildings effectively.Specifically, we aim to create a low-cost, easily updatable system that local volunteer guides and building managers can easily utilize.Compared to conventional guided tours, this audio guide system can be operated with fewer staff members and enables tourists to learn about the history and culture of the buildings at their own pace.One key feature of the audio guide system is its support for multiple languages, catering to inbound demand, and providing audio and text formats.Additionally, the system employs generative AI technology to streamline the creation and updating of guide content.By leveraging generative AI, local volunteers, and staff can easily generate and update the content without needing specialized knowledge.For the demonstration experiment, the Cultural Path Area in Higashi Ward, Nagoya City, was selected as the site to evaluate the effectiveness of the proposed audio guide system.In this experiment, we assessed tourist satisfaction, understanding, and convenience when using the system, and identified areas for improvement and operational challenges.The results confirmed that a low-cost, easyto-use audio guide system can contribute to the promotion of local tourism.This study proposes a novel approach to guide system development aimed at revitalizing local tourism.It provides a practical framework for collaboration between local communities and the tourism industry to promote the sustainable use of tourism resources.

本研究では、中国地方の国立大学（鳥取大学、島根大学、岡山大学、広島大学、山口大学）を対象に、旧軍施設の転用実態を整理する。鳥取県では、鳥取農業専門学校が旧演習場を演習林や砂丘試験施設として使用したほか、鳥取大学学芸学部が郊外の旧兵営に移転したほか。岡山県では、罹災した第六高等学校や新設の県立岡山農業専門学校が、郊外の元第17師団の旧兵営や旧兵器補給廠に移転し、新制岡山大学のメインキャンパスとなった。広島県では、罹災した広島文理大学、広島高等学校、広島工業専門学校は一時的に旧軍の教育施設を使用後、旧校地に復帰した。罹災した広島高等師範学校と広島女子高等師範学校、非罹災の広島青年師範学校は、旧兵営や旧被服廠に移転して新制に移行した。罹災した広島県立医学専門学校は旧兵営や旧海軍関連の病院を使用し、旧制医科大学に昇格したが、広島市内への移転が新制移行の条件とされたため、旧兵器補給廠へ移転した。

Belief in gendered social power imbalance (i.e. males are more powerful than females) leads to undesirable gender disparities, but little is known about the developmental origins of this belief, especially in Eastern cultures. We investigated the development onset of this belief by focusing on 4-7-year-old Japanese children while considering another belief (females are nicer than males) for comparison. In the dyadic context tasks, children saw pairs of animated characters depicting powerful-powerless or kind-unkind postures and judged the characters' gender (boy or girl). Results suggested both 'nice = female' and 'powerful = female' gender stereotypes in children. In the collective context tasks, children were presented with stories in occupational contexts, including multiple unspecified people and verbal cues, describing more explicitly the powerful and nice traits of the protagonists. The results replicated the 'nice = female' gender stereotype. Moreover, early 'powerful = male' gender stereotypes were seen in 6-year-old boys but not among girls in general. These findings demonstrate that Japanese children's beliefs regarding gender differences in power vary depending on the context in which male-female interactions are presented. Additionally, the study reveals that signs of the 'powerful = male' social power gender stereotype emerge around the ageof 6.
