However, research on indoor microplastic pollution remains limited, particularly in Japan. Therefore, the aim of this study was to investigate the shape and composition of microplastics in house dust from single-person households in four regions of Japan, including Tohoku, Kanto, Chubu, and Kansai. Micro-Fourier-transform infrared spectroscopy, a technique that combines infrared spectroscopy with optical microscopy was used, allowing a detailed analysis by obtaining the specific interference patterns and absorption spectra of the materials. The influence of building structure, flooring, and wall materials on microplastic composition in indoor environments was also investigated. This study addresses crucial knowledge gaps regarding the extent, forms, and sources of indoor microplastics. These findings contribute to the development of targeted measures to mitigate indoor microplastic exposure, support efforts to improve indoor air quality, and protect public health.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted an analysis by combining both objective survey of conversation time, conversation partners, and stay location information using sensing terminals and subjective evaluations by office workers using a questionnaire survey. As the work style transitioned from fixed seats pre-renovation to activity-based working post-renovation, the attendance rate analysis around each worker's personal workspace throughout the measurement period decreased from 74% to 60%, and the tendency to use various places in the office increased. Additionally, the number of conversation partners increased by 1.9 times on average and inter-department conversation rate increased from 46% to 53% when activity-based working was performed post-renovation. However, while the introduction of activity-based working significantly increased the level of communication satisfaction among workers in other departments, it tended to decrease the level of communication satisfaction within a department. This study maintains that organizational and operational efforts must sustain and promote intra-departmental communication when activity-based working is introduced and confirms that the introduction of activity-based working was effective in promoting interaction between office workers.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in a 2-way configuration, the performance of the connection in a direction orthogonal to the continuous beam may be suboptimal due to beam splitting. In this study, a new detail of a split orthogonal beam joint was proposed and 4 specimens were constructed and tested under quasi-static conditions. All the specimens attained the full-plastic flexural strength for the beams and exhibited a stable inelastic behavior. The specimen in which the depth of the orthogonal continuous beam was 100 mm greater than that of the split beam exhibited good inelastic cyclic behavior, whereas two other specimens with a split beam exhibited slipping and pinching. Minor fractures were observed in the tube wall; however, the strength and stiffness did not deteriorate significantly, though a slight pinched hysteresis was observed. In addition, a finite element analysis was conducted. The split beam was largely rotationally constrained by the bearing pressure of the concrete above and/or below the beam flange. If the split beam's flange was sufficiently inserted into the connection panel, the stiffness and strength were ensured.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pilot study assesses the accuracy of the Real-Time Kinematic Global Navigation Satellite System (RTK GNSS) in the Toyohashi South Side Station Square, aiming to validate its utility as a privacy-sensitive tool for studying public life, particularly in tracking movable chairs in urban settings. The findings indicate that RTK GNSS exhibits sufficient accuracy in recording the positions of movable chairs, thus facilitating public life studies. Given the variability of GNSS accuracy across environments, we propose the Silhouette Index as a metric for evaluating GNSS suitability across different scales. A Silhouette Index exceeding 0.9 signifies highly accurate data, suitable for comprehending the spatial arrangement and utilization of movable chairs in compact urban spaces. Conversely, an index below 0.8 indicates insufficient accuracy for this purpose. Nevertheless, RTK GNSS, akin to GPS, offers diverse applications in urban research. It can aid in analyzing pedestrian flows in city centers or expansive parks, as well as elucidating spatial behavioral patterns among distinct demographic groups in large-scale urban public spaces.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"7 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.12459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142324525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
