Mixbiotic society measures: Assessment of community well-going as living system
Social isolation is caused by the impoverishment of community (atomism) and
fragmentation is caused by the enlargement of in-group (mobism), both of which
can be viewed as social problems related to communication. To solve these
problems, the philosophical world has proposed the concept of "mixbiotic
society," in which individuals with freedom and diverse values mix and mingle
to recognize their respective "fundamental incapability" each other and
sublimate into solidarity. Based on this concept, this study proposes new
mixbiotic society measures to evaluate dynamic communication patterns with
reference to classification in cellular automata and particle reaction
diffusion that simulate living phenomena. Specifically, the hypothesis of
measures corresponding to the four classes was formulated, and the hypothesis
was validated by simulating the generation and disappearance of communication.
As a result, considering communication patterns as multidimensional vectors, it
found that the mean of Euclidean distance for "mobism," the variance of the
relative change in distance for "atomism," the composite measure that
multiplies the mean and variance of cosine similarity for "mixism," which
corresponds to the well-going of mixbiotic society, and the almost zero
measures for "nihilism," are suitable. Then, evaluating seven real-society
datasets using these measures, we showed that the mixism measure is useful for
assessing the livingness of communication, and that it is possible to typify
communities based on plural measures. The measures established in this study
are superior to conventional analysis in that they can evaluate dynamic
patterns, they are simple to calculate, and their meanings are easy to
interpret. As a future development, the mixbiotic society measures will be used
in the fields of digital democracy and platform cooperativism toward a
desirable society.Comment: 52 pages, 10 figure
Mixbiotic society measures: Comparison of organizational structures based on communication simulation
The philosophical world has proposed the concept of "mixbiotic society," in
which individuals with freedom and diverse values mix and mingle to recognize
their respective "fundamental incapability" each other and sublimate into
solidarity, toward solving the issues of social isolation and fragmentation.
Based on this concept, the mixbiotic society measures have been proposed to
evaluate dynamic communication patterns with reference to classification in
cellular automata and particle reaction-diffusion that simulate living
phenomena. In this paper, we applied these measures to five typologies of
organizational structure (Red: impulsive, Amber: adaptive, Orange: achievement,
Green: pluralistic, and Teal: evolutionary) and evaluated their features.
Specifically, we formed star, tree, tree+jumpers, tree+more jumpers, and
small-world type networks corresponding to each of five typologies, conducted
communication simulations on these networks, and calculated values for
mixbiotic society measures. The results showed that Teal organization has the
highest value of the mixism measure among mixbiotic society measures, i.e., it
balances similarity (mixing) and dissimilarity (mingling) in communication, and
is living and mixbiotic between order and chaos. Measures other than mixism
showed that in Teal organization, information is not concentrated in a central
leader and that communication takes place among various members. This
evaluation of organizational structures shows that the mixbiotic society
measures is also useful for assessing organizational change. In the future,
these measures will be used not only in business organizations, but also in
digital democratic organizations and platform cooperatives in conjunction with
information technology.Comment: 25 pages, 6 figure

Toward Digital Transformation of Personality Questionnaire: Development of Digitalized Questionnaires and Correlation Analysis between Personality Traits and Reactions Obtained during answering the Questionnaires
Personality traits evaluation is useful for effective supports of work and mental care. However, answering personality questionnaire demands much time and mental load for subjects (target persons). To reduce such time and load, one of the solutions is a digital transformation of personality questionnaire. Toward digital transformation of personality questionnaire, we developed digital questionnaires, which enable us to obtain not only answers but also answering reaction to questions. By using correlation analysis, we found significant correlations between 12 types personality traits and six reaction indicators obtained by the questionnaires. To develop a simpler and accurate digital questionnaires, it would be effective to develop a personality estimation method by using a combination of answer and reaction obtained by the questionnaire
Social Co-OS: Cyber-Human Social Co-Operating System
The novel concept of a Cyber-Human Social System (CHSS) and a diverse and
pluralistic 'mixed-life society' is proposed, wherein cyber and human societies
commit to each other. This concept enhances the Cyber-Physical System (CPS),
which is associated with the current Society 5.0, a social vision realised
through the fusion of cyber (virtual) and physical (real) spaces following
information society (Society 4.0 and Industry 4.0). Moreover, the CHSS enhances
the Human-CPS, the Human-in-the-Loop CPS (HiLCPS), and the Cyber-Human System
by intervening in individual behaviour pro-socially and supporting consensus
building. As a form of architecture that embodies the CHSS concept, the
Cyber-Human Social Co-Operating System (Social Co-OS) that combines cyber and
human societies is shown. In this architecture, the cyber and human systems
cooperate through the fast loop (operation and administration) and slow loop
(consensus and politics). Furthermore, the technical content and current
implementation of the basic functions of the Social Co-OS are described. These
functions consist of individual behavioural diagnostics, interventions in the
fast loop, group decision diagnostics and consensus building in the slow loop.
Subsequently, this system will contribute to mutual aid communities and
platform cooperatives.Comment: 14 pages, 14 figures. see

Micro-mechanical characterisation of hydrogen embrittlement in nano-twinned metastable austenitic stainless steel
Titanium ion induces necrosis and sensitivity to lipopolysaccharide in gingival epithelial-like cells
Gingival epithelial-like cells (GE-1) were cultured and used to examine the cellular responses of gingival tissues to varying concentrations of titanium (Ti) ions. Titanium ions at concentrations of more than 13 ppm significantly decreased the viability of GE-1 cells and increased LDH release from the cells into the supernatant, but had no significant effect on their caspase 3 activity. These data suggest that a high concentration of Ti ions induced necrosis of the GE-1 cells. Titanium ions at a concentration of 5 ppm significantly increased the level of CCL2 mRNA expression in GE-1 cells exposed to lipopolysaccharide derived from Porphyromonas gingivalis in a synergistic manner. Moreover, the mRNA expression levels of TLR-4 and ICAM-1 in GE-1 cells loaded with Ti ions at 9 ppm were significantly enhanced as compared with those in GE-1 cells without Ti stimulation. We suggest that Ti ions are in part responsible for monocyte infiltration in the oral cavity by elevating the sensitivity of gingival epithelial cells to microorganisms. Taken together, these data indicate that Ti ions may be involved in cytotoxicity and inflammation at the interfaces of dental implants and gingival tissue
Micro-mechanical characterisation of hydrogen embrittlement in nano-twinned metastable austenitic stainless steel
Micro-tensile tests were performed on single variants of nano-twinned 304 stainless steel with hard and soft orientations to determine the effect of nano-twins on hydrogen embrittlement in the metastable austenitic steel. Nano-twins were introduced into the 304 steel by deformation above the martensite-start temperature. The introduction of nano-twins increased the yield stress to 647 MPa for the hard-oriented crystals and 540 MPa for the soft-oriented crystals. For the soft-oriented crystals, the hydrogen charge induced quasi-cleavage although it did not change the uniform strain. For the hard-oriented crystals, the introduction of nano-twins retarded hydrogen-induced twin boundary separation. The relationship between the reduction of area and ultimate tensile strength revealed that the degree of strengthening and mitigation of hydrogen-induced ductility loss depended on the orientation of the nano-twins. These suggest that controlling the orientation and distribution of nano-twins allows for simultaneous strengthening and mitigation of hydrogen-induced ductility loss in metastable austenitic steel.Published version is available for viewing only.
