Lung function is often impaired in diabetic patients, especially in a restrictive pattern, which has recently been described as the diabetic lung. Since hypertension (HTN) is common in diabetic patients, our study investigated whether HTN acts as an aggravating factor in diabetic lung. Within the cross-sectional study from the 6th Korean National Health and Nutrition Examination Survey (KNHANES), fasting plasma glucose (FPG), blood pressure (BP), pulmonary function, and laboratory data were examined in 4644 subjects aged between 40 and 79 years. A multivariate regression model was used to investigate the relationship between BP, FPG, and pulmonary function. Lung function was significantly reduced in the HTN (p = 0.001), impaired fasting glucose (IFG) (p < 0.001), and diabetes mellitus (DM) (p < 0.001) groups. Next, a multivariate logistic regression model was used to derive the odds ratio (OR) of reduced lung function based on the presence of IFG, DM, and HTN. The OR of reduced forced vital capacity (FVCp < 80%) was 3.30 (p < 0.001) in the HTN-DM group and 2.30 (p < 0.001) in the normal BP-DM group, when compared with the normal BP-normal FPG group. The combination of HTN and DM had the strongest negative effect on FVC. The results presented in this study indicate that diabetes and hypertension have a synergistic association with impaired lung function.
With advances in artifcial intelligence technology, Voice-based Conversational Agents (VCAs) can now imitate human abilities, sometimes almost indistinguishably from humans. However, concerns have been raised that too much perceived similarity can trigger threats and fears among users. This raises a question: Should VCAs be able to imitate humans perfectly? To address this, we explored what infuences the negative aspects of user experience in humanlike VCAs. We conducted a qualitative exploratory study to elicit participants' perceptions and feelings of human-like VCAs through comparable video prototypes of human-agent conversation and human-human conversation. We discovered that the dialogues of the human-likeness outside of the expressed purpose of a VCA and expressions pretending to come from a human identity could lead to negative experiences with VCAs. Based on our fndings, we discussed design directions for overcoming potential issues of human imitation.

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.
