Shared mechanisms in pragmatic enrichment with contextual and lexical alternatives
Deconstructing subjective unmet healthcare needs
Background: Despite widespread efforts by many countries to reduce the prevalence of unmet healthcare needs within their populations, there remains a scarcity of research systematically exploring the components of these needs. Objectives: This study aims to deconstruct subjective unmet healthcare needs into two distinct components: the experience of subjective healthcare needs (the "Needs" component) and the experience of unmet needs contingent o…
The Conjunction Fallacy
The conjunction fallacy is the well-documented reasoning error on which people rate a conjunction A&B as more probable than one of its conjuncts, A. Many explanations appeal to the fact that B has a high probability in the given scenarios, but Tentori et al. (2013) have challenged such approaches. They report experiments suggesting that degree of confirmation—rather than probability—is the central determinant of the conjunction fallacy. In this p…
Characteristics Associated With Financial or Non-financial Barriers to Healthcare in a Universal Health Insurance System
While many studies have explored the financial barriers to healthcare, there is little evidence regarding the non-financial barriers to healthcare. This study identified characteristics associated with financial and non-financial barriers to healthcare and quantified the effects of these characteristics in South Korea, using a nationally representative longitudinal survey dataset. Overall, 68,930 observations of 16,535 individuals aged 19 years a…
Question-answer dynamics in deductive fallacies without language
We introduce purely visual paradigms that convey the logical structure of illusory inferences from disjunction: (a AND b) OR c, a |- b. Although the logical information was conveyed entirely via non-linguistic means, we found that the visual paradigms induce reasoning fallacies, though less attractive than their linguistic counterparts. The visual paradigms highlight the role of alternative-based reasoning, or question-answer dynamics, as they co…
Association between Handgrip Strength and Cognitive Function in Older Adults
Accumulating research indicates that handgrip strength is associated with cognitive function. Studies have also shown the difference in cognitive decline between males and females. We investigated the association between baseline handgrip strength and later cognitive function in older adults according to sex using the dataset from Korean Longitudinal Study of Aging (2006-2018). Overall, 9707 observations of 1750 participants (989 males and 761 fe…
Intervention in deontic reasoning
The ‘if p, ought p’ problem, famously known as Zvolenszky’s puzzle (Zvolenszky 2002), questions whether possible world semantics can assign proper truth conditions to sentences of the form ‘if p, ought p’. This paper suggests that it is not a problem of possible worlds semantics of modality, but rather, the ‘if p, ought p’ problem reveals the counterfactual nature of deontic modals which otherwise would have gone unnoticed. I propose that a count…
Which Occupation is Highly Associated with Cognitive Impairment? A Gender-Specific Longitudinal Study of Paid and Unpaid Occupations in South Korea
Background : To examine the associations between paid and unpaid occupations and the risk of cognitive impairment with respect to gender in a middle-aged population using the dataset of a nationally representative longitudinal survey. Methods : Overall, 24,925 observations of 5865 participants aged 45-64 years were sampled from the seven waves of the Korean Longitudinal Study of Ageing (2006-2018). A dichotomous outcome variable was derived based…
Differential Risk of Cognitive Impairment across Paid and Unpaid Occupations in the Middle-Age Population
To examine and quantify the risk of cognitive impairment across a variety of occupations including unpaid work in a middle-age population using the dataset of a nationally representative longitudinal survey. A total of 20,932 observations of 5865 subjects aged 45-64 were obtained from six waves of the Korean Longitudinal Study of Aging (2006-2016). A dichotomous outcome variable was constructed on the basis of the Korean Versions of the Mini-Ment…
A Reversal of the Association between Education Level and Obesity Risk during Ageing
This study aimed to examine and quantify obesity risk across different education levels during ageing using the dataset of a nationally representative longitudinal survey. A total of 45,391 observations of 9991 individuals aged ≥45 years were included in this study. Obesity was defined as a body mass index of ≥25, according to a guideline for Asians by the World Health Organization, and education level was grouped into three categories. Socio-dem…
Factors contributing to educational differences in obesity among women
We suggest that to effectively mitigate the high prevalence of obesity among less-educated women, it may be necessary to help low-educated women who do not feel stressful develop strategies to combat their higher risk of obesity. We also suggest the need to conduct decomposition studies in countries which show significant relationships between education and obesity among women, and to create targeted policies to reduce this population's overall r…
Associations of socioeconomic and religious factors with health
These findings demonstrate the important role of socioeconomic and religious factors in health in China and Korea as well as clear differences in this regard. Further cross-national studies are needed to provide a better understanding of the relationship between socioeconomic and religious factors and health and to draft appropriate health improvement policies in both countries
Context updates in head-final languages
This paper argues that extant approaches to presupposition projection that eitherrely on strict linear order (Schlenker, 2009) or hierarchy (Romoli and Mandelkern, 2017) cannotprovide a uniform account of data drawn from head-final languages. While building onSchlenker’s theory, this paper resolves the issues by restricting the calculation of local contextsto specific points in the parsing process. The consequence is that the theory makes a predi…
Modifying effects of education on the association between lifestyle behaviors and the risk of obesity
Education may be a risk factor for obesity through its interplay with lifestyle behaviors. Further research is required to examine these findings in different socio-cultural settings
Factors associated with long-stay status in patients with schizophrenia
BACKGROUND: Admissions lasting over six months (long-stay) occur frequently among patients with schizophrenia in South Korea. AIMS: To identify some patient-level and institution-level factors associated with long-stay status of patients with schizophrenia. METHODS: This is a retrospective cross-sectional study. We analysed a nationwide population-based reimbursement claims data set consisting of 496,338 claims for 58,287 patients with schizophre…
Why is high-risk drinking more prevalent among men than women? evidence from South Korea
We came to a finding that gender-specific HRD tendency is the greatest contributor to gender differences in HRD. Therefore, to effective reduce HRD, it will be necessary to understand gender differences in socioeconomic characteristics between men and women but also take notice of such differences in sociocultural settings as they experience. And it will be also required to prepare any gender-differentiated intervention strategy for men and women

Evidence for an Incipient Decline in Numbers of Missing Girls in China and India
The apparently inexorable rise in the proportion of "missing girls" in much of East and South Asia has attracted much attention among researchers and policymakers. An encouraging trend was suggested by the case of South Korea, where child sex ratios (males to females under age 5) were the highest in Asia but peaked in the mid-1990s and normalized thereafter. Using census data, we examine whether similar trends have begun to manifest themselves in…
Breast-feeding in South Korea
Objective To investigate factors influencing the practices of partial breast-feeding (PBF) and exclusive breast-feeding (EBF). Design A national, cross-sectional survey was conducted among married women aged 15–49 years from May to August 2003. Setting South Korea. Subjects A total of 865 mothers answered questions regarding the feeding practices of their youngest baby, born between January 2001 and May 2003. Results The initiation rates of PBF a…
The Relation of Son Preference and Religion to Induced Abortion
This paper explores the factors that influence the practice of induced abortion in a very low fertility society, with particular emphasis on son preference and three distinct religions: Confucianism, Buddhism and Christianity. Using multivariate logistic regression models fitted by the generalized estimating equation (GEE) method, this paper analysed the data collected by the 2000 Korea National Fertility and Family Health Survey of 6348 married …
The Decline of Son Preference in South Korea
For years, sex ratios at birth kept rising in South Korea despite rapid development. We show that this was not an anomaly: underlying son preference fell with development, but the effect of son preference on sex ratios at birth rose until the mid-1990s as a result of improved sex-selection technology. Now South Korea leads Asia with a declining sex ratio at birth. We explore how son preference was affected by development and by public policy. Dec…
Why is Son preference so persistent in East and South Asia? a cross-country study of China, India and the Republic of Korea
Son preference has persisted in the face of sweeping economic and social changes in the countries studied here. We attribute this persistence to their similar family systems, which generate strong disincentives to raise daughters whether or not their marriages require dowries while valuing adult women's contributions to the household. Urbanisation, female education and employment can only slowly change these incentives without more direct efforts…
Fertility and Son Preference in Korea
In Korea, total fertility declined from 6.0 in 1960 to 1.6 in 1990, in spite of a strong preference for male offspring. This paper addresses the notion that son preference hinders fertility decline, and examines the effects of patriarchal relations and modernization on fertility using the 1991 Korea National Fertility and Family Health Survey. It was found that women who have a son are less likely to have another child, and that women with a son …
