Carbon monoxide (CO) is a toxic, hazardous gas that has a colorless and odorless nature. On the other hand, CO possesses some physiological roles as a signaling molecule that regulates neurotransmitters in addition to its hazardous effects. Because of the dual nature of CO, there is a need to develop a sensitive, selective, and rapid method for its detection. Herein, we designed and synthesized a turn-on fluorescence probe, 2-(2′-nitrophenyl)-4(3H)-quinazolinone (NPQ), for the detection of CO. NPQ provided a turn-on fluorescence response to CO and the fluorescence intensity at 500 nm was increased with increasing the concentration of CO. This fluorescence enhancement could be attributed to the conversion of the nitro group of NPQ to an amino group by the reducing ability of CO. The fluorescence assay for CO using NPQ as a reagent was confirmed to have a good linear relationship in the range of 1.0 to 50 µM with an excellent correlation coefficient (r) of 0.997 and good sensitivity down to a limit of detection at 0.73 µM (20 ppb) defined as mean blank+3SD. Finally, we successfully applied NPQ to the preparation of a test paper that can detect CO generated from charcoal combustion. Molecules, 28(9), art. no. 3654; 2023

This study aims to explore its potential as research material for analyzing Indian cinema using quantitative research methods. Mainstream film research is centered on “qualitative research,” which analyzes works of specific film directors. However, in qualitative research, the arbitrary selection of these works and the director should be appropriate for maintaining the aptness of the analysis. To compensate for the weaknesses of qualitative research in film research, digital humanities (DH) is used, which is a quantitative research method employed to examine word frequency and analyze text in studies of English literature and drama. I aim to adopt this method for film research and consider new possibilities for film research.

In this paper, we use micro data on a large number of European countries from the Survey of Health, Ageing and Retirement in Europe (SHARE) to examine the wealth accumulation (saving) behavior of the retired elderly in Europe. To summarize our main findings, we find that less than half of the retired elderly in Europe are decumulating their wealth and that the average wealth accumulation rate of the retired elderly in Europe is positive though relatively moderate (6.6% over a 3-year period). These findings strongly suggest that the Wealth Decumulation (or Retirement Saving) Puzzle (the tendency of the retired elderly to not decumulate their wealth or to decumulate their wealth more slowly than expected) applies in the case of Europe. Moreover, our regression results suggest that bequest motives, generous public pension systems, and the reluctance of retired elderly homeowners to sell or borrow against their owner-occupied housing are the primary explanations for the existence of the Wealth Decumulation Puzzle in Europe.

This study uses a catastrophic earthquake in 1923 to analyse the long-term effects of a natural disaster on children's health. I find that fetal exposure to Japan's Great Kanto Earthquake had stunting effects on girls in the devastated area. Disaster relief spending helped remediate stunting among boys by late primary school age, whereas it did not ameliorate girls' stunting, suggesting a prenatal selection mechanism and compensating investment after birth. While the maternal mental stress via the fear of vibrations and anticipation of future aftershocks played a role in the adverse health effects, the maternal nutritional stress via physical disruption also enhanced those effects.

In this paper, we study language used by suicidal users on Reddit social media platform. To do that, we firstly collect a large-scale dataset of Reddit posts and annotate it with highly trained and expert annotators under a rigorous annotation scheme. Next, we perform a multifaceted analysis of the dataset, including: (1) the analysis of user activity before and after posting a suicidal message, and (2) a pragmalinguistic study on the vocabulary used by suicidal users. In the second part of the analysis, we apply LIWC, a dictionary-based toolset widely used in psychology and linguistic research, which provides a wide range of linguistic category annotations on text. However, since raw LIWC scores are not sufficiently reliable, or informative, we propose a procedure to decrease the possibility of unreliable and misleading LIWC scores leading to misleading conclusions by analyzing not each category separately, but in pairs with other categories. The analysis of the results supported the validity of the proposed approach by revealing a number of valuable information on the vocabulary used by suicidal users and helped to pin-point false predictors. For example, we were able to specify that death-related words, typically associated with suicidal posts in the majority of the literature, become false predictors, when they co-occur with apostrophes, even in high-risk subreddits. On the other hand, the category-pair based disambiguation helped to specify that death becomes a predictor only when co-occurring with future-focused language, informal language, discrepancy, or 1st person pronouns. The promising applicability of the approach was additionally analyzed for its limitations, where we found out that although LIWC is a useful and easily applicable tool, the lack of any contextual processing makes it unsuitable for application in psychological and linguistic studies. We conclude that disadvantages of LIWC can be easily overcome by creating a number of high-performance AI-based classifiers trained for annotation of similar categories as LIWC, which we plan to pursue in future work.

This paper aims to clarify Charlotte Perriand’s (1903–1999) formation of the notion of the “vacuum” through a reading of The Book of Tea written by Kakuzo Okakura in 1906, using the French version ...

Nursing records are an account of patient condition and treatment during their hospital stay. In this study, we developed a system that can automatically analyze nursing records to predict the occurrence of diseases and incidents (e.g., falls). Text vectorization was performed for nursing records and compared with past case data on aspiration pneumonia, to develop an onset prediction system. Nursing records for a patient group that developed aspiration pneumonia during hospitalization and a non-onset control group were randomly assigned to definitive diagnostic (for learning), preliminary survey, and test datasets. Data from the preliminary survey were used to adjust parameters and influencing factors. The final verification used the test data and revealed the highest compatibility to predict the onset of aspiration pneumonia (sensitivity = 90.9%, specificity = 60.3%) with the parameter values of size = 80 (number of dimensions of the sentence vector), window = 13 (number of words before and after the learned word), and min_count = 2 (threshold of wordcount for word to be included). This method represents the foundation for a discovery/warning system using machine-based automated monitoring to predict the onset of diseases and prevent adverse incidents such as falls.

Abstract This paper aims to clarify the influence of “Mingei (Folk Crafts)” on the creative theories of French architect and interior designer Charlotte Perriand (1903–1999) and reconsider an aspect of modern architecture. First, in Section 2, this paper examines Perriand’s articles before her encounter with “Folk Crafts”. Section 3 traces her experience of “Folk Crafts” during her time in Japan, and finally, Sections 4 and 5 compare the thoughts of Yanagi and Perriand. Perriand integrated the ideas of Yanagi’s “Folk Crafts” from her interest in vernacular buildings, and this matured into a spatial theory of the “contact”. This hand‐based “contact” was not a rejection of machine‐driven civilization; rather it had the characteristic of universality as far as the sense of touch was based on the human physiological sense.
