A layered alkali silicate, octosilicate (Na2Si8O17), modified with the controlled amount and ratio of octadecyl and phenyl groups was synthesized to control the spatial distribution of the two functional groups and then achieve the effective and selective adsorption of 4-nonylphenol from aqueous solution. Octosilicates modified with the varied amount and ratio of the attached octadecyl/phenyl groups (0.7/0.7, 0.4/0.4, 0.3/0.3, and 0.4/1.0 groups per Si8O17 unit, respectively) were prepared by the reaction of the dodecylammonium-exchanged octosilicate with a controlled amount of octadecyltrichlorosilane and phenyltrichlorosilane sequentially. The adsorption of 4-nonylphenol from water on the four silylated octosilicates was investigated to find that the adsorption isotherm for the silylated octosilicate bearing the surface coverage with octadecyl/phenyl groups of 0.7/0.7 groups per Si8O17 unit was H-type, while the other silylated octosilicates gave S-type adsorption isotherms. The silylated octosilicate having surface coverage with octadecyl/phenyl groups of 0.7/0.7 groups per Si8O17 unit selectively adsorbed 4-nonylphenol from aqueous mixture of 4-butylphenol, 4-hexylphenol, and 4-nonylphenol.
This study investigated the impact of a visit to a Manga museum in Japan through nostalgic recollections. Twenty-five adult visitors were interviewed about their childhood memories of experiencing manga from reading books as well as watching anime on television following a visit to the Osamu Tezuka Manga Museum in Takarazuka, Japan. From 76 episodic and autobiographical memories, five themes of impact emerged which speak powerfully to the significant influence and power of Osamu Tezuka's manga and anime on the visitors' lives as children, and of the power of the museum experience to unlock distant latent memories and reconnect with their own sense of self-identity. Moreover, the visitors' own testimony of the impact of manga continued to manifest positively in their lives to the present day as life lessons of enjoyment, morality, and intergenerational learning.David Anderson (david.anderson@ubc.ca) is Professor at the University of British Columbia, Canada.

Understanding visitors' retrospective perceptions in museums as they connect objects with their personal identities and life stories, as well as their collective social identities, is of considerable interest to the museum field. This study employed a multiple case narrative methodology to understand the common perceptual themes of post‐World War II Japanese society between 1955 and 1970 (Shōwa 30–45) held by older Japanese adults following their visit to a Shōwa‐era social history museum. From an inductive analysis of n = 29 face‐to‐face interviews, five sustaining characteristic themes emerged which were later interpreted through the historical backdrop of the period together with Carstensen's socioemotional selectivity theory (SST) to provide deeper interpretation of the themes. Through their museum experiences, the visitors recalled a society characterized by; (1) close human relationships; (2) strong values and morals; (3) freedom, openness, and peace; (4) struggles and poverty, which could be overcome with patient effort; and, (5) hopes and dreams. These themes were key to the visitors' own identity and values – both personal and collective. This study contributes to a broader understanding of the power of museum experiences to evoke strong nostalgic recollections by Japanese citizens of their unique personal and collective identities, and the characteristics their retrospective memories from the perspective of the present day vantage point. It speaks to the power of the museum, not as a learning or knowledge acquisition experience, but rather in its power to affirm both personal and collective identity and the values that were retrospectively important for these visitors looking back.
The objective of this study is to understand the evaluation and image of spaces using artificial turf. This study comprised of visual impression experiments in the indoor and urban spaces and interviews. Factor analysis and multiple regression analysis were conducted using the results of visual impression experiments. As a result, it was found that the factors that affect the pleasantness of a space with artificial turf are preference and idyllic in an indoor space, and vitality and preference in an urban space. From the interview, we understood the impressions that people who use spaces with artificial turf on a daily.
survey, attitude survey, and accumulation survey. From request surveys, the request to install space for eating and drinking could be reduced by installment parklets. The attitude survey showed that the notices increased interest in the city. The accumulation survey revealed that installment for relaxation in a variety of positions is effective in promoting conversation while playing and long stays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
