Exploration of the Determinants of Subjective Health and Depression Using Korean Longitudinal Study of Aging Data.

Aging is an imperative issue in Korean society, and a healthy life is important for a better quality of life for older adults. Therefore, the purpose of this research was to investigate the determinants of subjective health and depression in middle-aged and elderly Korean individuals. This study used three attributes as the determinants of subjective health and depression, including the curve linear effect of medical expenses and eating-out expenses and the linear impact of regular exercise. We utilized the Korean Longitudinal Study of Aging (KLOSA) to determine the associations between five attributes: subjective health, depression, medical expenses, eating-out expenses, and regular exercise. Research panel data were employed as the data source. The study period was between 2018 and 2020. This research implemented various multiple linear panel regression econometric analysis instruments: ordinary least squares, random effects, and fixed effects. The mean age of survey participants was 72.10 years, and 35 percent of participants were female. The number of observations for data analysis was 7197. The results revealed that medical and eating-out expenses had a curved linear effect on subjective health and depression. Moreover, regular exercise positively affected subjective health and resulted in less depression. These findings may inform policy decisions that promote regular exercise and manage medical and eating-out expenses, thereby enhancing subjective health and mitigating depression.

The Relationship between Food Healthiness, Trust, and the Intention to Reuse Food Delivery Apps: The Moderating Role of Eco-Friendly Packaging.

The goal of this research is to investigate the relationship among food healthiness, trust, and the intention to reuse food delivery apps. Another purpose of this work is to examine the moderating effect of eco-friendly food packaging on the association between food healthiness and trust in food delivery apps. A survey was the main instrument for this work, with Amazon Mechanical Turk being used to collect the relevant data, resulting in a total of 343 observations. PROCESS model 7 was employed to test the research hypotheses. The results reveal that the intention to reuse is positively impacted by trust and food healthiness in food delivery apps. The results also uncover a significant moderating impact of eco-friendly packaging on the relationship between food healthiness and trust. The high food healthiness and high eco-friendly packaging group has the highest level of trust, while the low food healthiness and low eco-friendly packaging group has the lowest. The results of this research are therefore important because they clarify the relationship among these four attributes. Moreover, the results of this study have notable managerial implications.

Assessing Antecedents of Restaurant's Brand Trust and Brand Loyalty, and Moderating Role of Food Healthiness.

The purpose of this research was to apply DINESERV to a food brand: Shake Shack. Six sub-dimensions (e.g., taste, healthiness, employee service, price fairness, ambience, and convenience) were adopted. This study used brand trust and brand loyalty to explain attributes. This research additionally assessed the moderating impact of healthiness on the relationship between taste and brand loyalty. For data collection, this study used Amazon Mechanical Turk. The main instrument of this research is a survey. The number of valid observations was 353. Confirmatory factor analysis and a correlation matrix were used to ensure the convergent and discriminant validity of measurement items. Structural equation modeling was employed for hypothesis testing. Plus, Hayes process macro model 1 was employed to test the moderating effect of healthiness. Results indicated that brand trust was positively associated with taste (p < 0.05), employee service (p < 0.05), and ambience (p < 0.05), while brand loyalty was positively associated with taste (p < 0.05), healthiness (p < 0.05), price fairness (p < 0.05), ambience (p < 0.05), and brand trust (p < 0.05). However, the convenience of casual restaurants appeared as a non-significant attribute to account for both brand trust and brand loyalty. The results also revealed that healthiness negatively moderates the relationship between taste and brand loyalty (p < 0.05). This study sheds light on the literature by demonstrating the accountability of DINESERV to casual dining customer behavior. Also, this research presents information for the assistance of brand management in the domain of casual dining sector.

Relationship between Subjective Health, the Engel Coefficient, Employment, Personal Assets, and Quality of Life for Korean People with Disabilities.

The aim of this research is to examine the effect of subjective health on the quality of life of Korean people with disabilities. The second goal of this study is to examine the effect of the Engel coefficient on quality of life. Additionally, this study is conducted to inspect the effect of employment and personal assets on quality of life. Further, in this work, the moderating effect of personal assets on the association between employment and quality of life for people with a disability is explored. The Panel Survey of Employment for the Disabled served as the source of data. The study period ranges from 2016 to 2018. To test the research hypotheses, this study adopted econometric analyses, namely, ordinary least squares, fixed effect, and random effect models. The results revealed that the quality of life for people with disabilities is positively influenced by subjective health, employment, and personal assets. In contrast, the Engel coefficient exerts a negative impact on quality of life. Plus, the finding indicates that personal assets negatively moderate the relationship between employment and quality of life for people with disabilities. This research is aimed at presenting policy implications for the welfare of people with disabilities.

The Moderating Effect of Personal Assets in the Relationships between Subjective Health, Housing Expense, and Life Satisfaction for Korean Middle and Old-Aged.

The proportion of the elderly in Korea has increased. Given the circumstances, this research is intended to explore the characteristics of the elderly. The aim of this research is to explore the antecedents of life satisfaction in the Korean elderly using subjective health. Next, the goal of this research is to appraise the moderating effect of personal assets in the relationship between life satisfaction and housing expenses. The study data consist of 7199 observations from the 2018 and 2020 waves of the Korean Longitudinal Study of Aging (KLOSA). This research uses econometric analysis to test the research hypotheses, which include ordinary least squares, fixed-effects, and random-effects regression analyses. Following ordinary least squares, fixed-effects, and random-effects regression analyses, the results indicate a positive influence of subjective health on older Koreans' life satisfaction. Additionally, personal assets positively moderate the association between housing expense and life satisfaction, the most valuable finding of the study. This research sheds light on the literature by revealing the moderating effect on the relationship between housing expense and life satisfaction. Moreover, the results could be used for better policy design with respect to the middle- and old-aged members Korean society.
