    This paper introduces the Trust-Distrust Model and its applications, extending the Bounded Confidence Model, a theory of opinion dynamics, to include the relationship between trust and mistrust. In recent years, there has been an increase in the number of cases in which the prerequisites for conventional communication (e.g., the other person’s gender, appearance, tone of voice, etc.) cannot be established without the exchange of personal information. However, in recent years, there has been an increase in the use of personal information, such as letters and pictograms “as cryptographic asset data” for two-way communication. However, there are advantages and disadvantages to using information assets in the form of personalized data, which are excerpts of personal information as described above. In the future, the discussion of trust value in the above data will accelerate in indicators such as personal credit scoring. In this paper, the Trust-Distrust Model will be discussed with respect to theories that also address charismatic people, the effects of advertising, and social divisions. Furthermore, simulations of the Trust-Distrust Model show that 55% agreement is sufficient to build social consensus. By addressing this theory, we hope to use it to discuss and predict social risk in future credit scoring discussions

    地域で生活する高齢者・障害者にとって,住宅環境の整備は必須の要件である。津山市では在宅生活を支援する立場にある保健婦やホームヘルパー,作業療法士等保健・福祉関係者と,建築関係者が共同で支援チームをつくり住宅改造に関わってきた。本研究では,この支援チームが関わった事例と直接関わらないで当事者と業者のみで改造を実施した事例を比較し,支援チームが関わることの効果をみた。調査方法は,各事例の家庭を訪問して面接聞き取り調査を行った。調査内容は調査票を用いて改造箇所,生活空間,介護量,外出の状況について尋ねた。改造前後の変化を比較して,支援チームの効果について以下のことが明らかになった。 1.支援チームの関与による浴室の改造は,入浴が可能となり生活空間が広がるなど改善が認められた。 2.離床を目的にした玄関・廊下・居室の改造は,外出などの日常生活行動を広げ,本人のQOLを高めることに役立つ。以上より住宅の改造が,介護者の介護負担を必ずしも直接軽減するとは限らないが,高齢者・障害者の介護の質に変化を与えることが示唆された。The maintenance and improvement of housing environments are essential for aged and handicapped persons living in a local communities. The support team consists of public health nurses, home helpers, occupational therapists and architects took part in giving an advices for house remodeling in Tsuyama City. We compared the effectiveness of the participation of the team before and after remodeling of housing environment. An interview was conducted at each cases for places of remodeling, living spaces, quantity of care and ease of going. The results are as follows ; 1. The remodeling of bathrooms, participating support team improved the living spaces to be able to take bath. 2. The remodeling of entrances and corridors for leaving beds, improved the living space and the QOL of care recipients. The results suggest that the remodeling of houses dose not always lighten care burdens for caring, but changes the quality of care for aged and handicapped persons

    Lunar Phase-Dependent Expression of Cryptochrome and a Photoperiodic Mechanism for Lunar Phase-Recognition in a Reef Fish, Goldlined Spinefoot

    Lunar cycle-associated physiology has been found in a wide variety of organisms. Recent study has revealed that mRNA levels of Cryptochrome (Cry), one of the circadian clock genes, were significantly higher on a full moon night than on a new moon night in coral, implying the involvement of a photoreception system in the lunar-synchronized spawning. To better establish the generalities surrounding such a mechanism and explore the underlying molecular mechanism, we focused on the relationship between lunar phase, Cry gene expression, and the spawning behavior in a lunar-synchronized spawner, the goldlined spinefoot (Siganus guttatus), and we identified two kinds of Cry genes in this animal. Their mRNA levels showed lunar cycle-dependent expression in the medial part of the brain (mesencephalon and diencephalon) peaking at the first quarter moon. Since this lunar phase coincided with the reproductive phase of the goldlined spinefoot, Cry gene expression was considered a state variable in the lunar phase recognition system. Based on the expression profiles of SgCrys together with the moonlight's pattern of timing and duration during its nightly lunar cycle, we have further speculated on a model of lunar phase recognition for reproductive control in the goldlined spinefoot, which integrates both moonlight and circadian signals in a manner similar to photoperiodic response

    Induction of neurite outgrowth by α-phenyl-N-tert-butylnitrone through nitric oxide release and Ras-ERK pathway in PC12 cells

    It has previously been suggested that the spin trap agent α-phenyl-N-tert-butylnitrone (PBN) induces neurite outgrowth through activation of the Ras-ERK pathway in PC12 cells. However, the chemical properties of PBN contributing to its biological function and the detailed mechanism for the activation of Ras by PBN remain unknown. This study demonstrates that the hydrophobic structure of PBN is related to the activation of Ras, by comparing with hydrophilic analogues of PBN. [14C]-labelled PBN was found to localize in the lipid fraction and activate Ras indirectly. On the other hand, neurite outgrowth by PBN was inhibited by a nitric oxide (NO) scavenger. Moreover, the neurite outgrowth induced by PBN and the NO donor NOR4 was inhibited by the dominant negative Ras or MAPK/ERK inhibitor. Taken together, these results suggest that PBN is incorporated into the plasma membrane and induces neurite outgrowth in PC12 cells by activating the Ras-ERK pathway through NO releas
