Objectives: We used the Korea Health Panel Annual Data 2019 to analyze factors related to visits to both Korean medicine and Western medicine (WM) outpatient clinics among patients with overweight and obesity. Methods: The inclusion criteria for this study are as follows: 1) adults over 18 years of age, 2) overweight or obese with a body mass index of 25.0 or more, 3) visited WM outpatient clinics at least once during 2019. Total 2,963 individuals were included in WM group or integrative medicine (IM) group. Using the Andersen healthcare utilization model, factors related to healthcare utilization of the participants were classified. Binomial logistic regression analysis was used to analyze factors associated with IM use. Results: Among the participants, 80.49% (n=2,385) were assigned to WM group and 19.51% (n=578) to IM group. As a result of the regression analysis, factors significantly related to the use of IM included the elderly over 65 years of age, sex (men), college or higher education level, residential area (Gwangju/Jeolla/Jeju), presence of cancer, and presence of musculoskeletal disease. The main diagnosis associated with both WM and IM use was most frequently musculoskeletal conditions. Also, IM group received WM treatment for musculoskeletal conditions more frequently compared to WM group. Conclusions: This study is the first to analyze healthcare utilization patterns among overweight or obese patients in Korea. The current findings suggest that the presence of musculoskeletal conditions, especially in this population, may be strongly associated with concurrent use of IM services.

Objectives : Anxiety is an important mental health symptom associated with healthcare utilization. This research aims to identify the demographic, socio-economic, and health-related factors associated with the use of Korean medicine (KM) treatments in adults experiencing anxiety. Methods : We conducted a cross-sectional analysis using the Korea Health Panel Annual Data 2019. Logistic regression models were employed to examine the relationships between KM utilization and various factors such as economic activity, perceived stress levels, and presence of physical discomfort. The study sample included 552 adults experiencing anxiety. Results : Among the subjects, 19.20% were using both conventional treatment and KM treatment. The analysis revealed that individuals engaged in economic activities were more likely to use KM treatments compared to those who were not (odds ratio [OR] = 2.207, 95% confidential interval [CI] = 1.316 to 3.699). Additionally, individuals reporting high levels of pain or discomfort showed a significantly higher likelihood of using both KM and conventional medical services (OR = 2.933, 95% CI = 1.645 to 5.231). Musculoskeletal conditions were the most common reason for KM utilization among the study participants. Conclusion : The findings suggest that economic activity and the severity of physical discomfort significantly influence the use of KM treatments among adults with anxiety. These insights could inform healthcare policy and the integration of KM services into broader health management strategies for anxiety.

The purpose of this study was to identify latent classes in school readiness which were measured by both parents and teachers, and to test the relationship with school adaption, academic abilities, problematic behaviors, self-esteem, and happiness. Latent Profile Analysis (LPA), MANOVA, and one-way ANOVA were conducted using the data of 1,154 1st to 3rd grade elementary school students, and the data was collected between the 7th year (2014) to the 10th year (2017) from the Korean Children and Youth Panel Study. The results of study were as follows. First, four school readiness groups were identified: the consistent low group, parent perceived high group, the teacher perceived high group, the consistent high group. Second, the consistent high group and the teacher perceived high group showed relatively better academic abilities and school adaption than the consistent low group. Furthermore, the consistent high group showed higher academic abilities, self-esteem, and happiness, but lower problematic behaviors than the consistent low group. The findings of this study could be utilized as preliminary data for understanding school readiness to promote successful school adaption and psychological well-being of children.

Crops and varieties are mostly affected by temperature, the amount of precipitation, and duration of sunshine. This study aims to identify the weather factors that directly influence to apple yield among the series of daily measured weather variables during growing seasons. In order to identify them, 1) a priori natural scientific knowledge with respect to the growth stage of apples and 2) pure statistical approaches to minimize bias due to the subject selection of variables are considered. Each result estimated by the Panel regression using fixed/random effect models is evaluated through suitability (i.e., Akaike information criterion and Bayesian information criterion) and predictability (i.e., mean absolute error, root mean square error, mean absolute percentage). The Panel data of apple yield and weather factors are collected from fifteen major producing areas of apples from 2006 to 2013 in Korea for the case study. The result shows that variable selection using factor analysis, which is one of the statistical approaches applied in the analysis, increases predictability and suitability most. It may imply that all the weather factors are important to predict apple yield if statistical problems, such as multicollinearity and lower degree of freedom due to too many explanatory variables used in the regression, can be controlled effectively. This may be because whole growth stages, such as germination, florescence, fruit setting, fatting, ripening, coloring, and harvesting, are affected by weather.

This longitudinal study examined the influence of substandard housing conditions and housing affordability on physical and mental health. Using data from the Korea Welfare Panel Study, this study followed 8,583 adults who continued to participate in the survey from 2009 to 2013. Multivariate analyses involved linear and logistic regression models with the hybrid method that incorporates both fixed and random effects. Results show that substandard housing conditions and excess housing cost burden had significant adverse effects on adults' mental health (e.g., depressive symptoms). About one fourth of the entire sample and one third of those in poverty reported having lived in substandard housing conditions. Additionally, nearly one fourth of those in poverty reported having experienced excess housing cost burden, which is 4 times greater than that of the entire sample. Our findings show that a substantial proportion of individuals, particularly among the poor, have a difficulty in accessing to decent, affordable housing, and that housing assistance may have additional benefits of improving the mental health of individuals with housing issues.

This study was conducted to provide the basis for the establishment of various youth policies by analyzing and validating the mediated effects of ego resilience on the impact of adolescents' self-rated health on life satisfaction. The population consisted of a nationally representative sample of adolescents(n=1,979) in high school first grade student who completed the Korean Children and Youth Panel Survey(KCYPS) in 2016. The study analyzed the data by descriptive analysis, t-test, ANOVA, Pearson's correlation coefficients and path modeling, using the SPSS and AMOS program. The result is following; Self-rated health has significant effects of ego-resilience(β=.26, p<.05). Self-rated health(β=.18, p<.05) and ego-resilience(β=.45, p<.05) have shown significant implications for life satisfaction. In addition, ego-resilience have been shown to be partial mediation effect between Self-rated health and life satisfaction. The results revealed that the adolescents who scored high on self-rated health were better the life satisfaction, and ego-resilience partially mediated the relationship between self-rated health and life satisfaction in adolescents. In order to increase the life satisfaction for adolescent, it was confirmed that a multi-dimensional approach is needed to consider the self-rated health as well as self-resilience.

This paper adopts a distributive performance process model of in-work poverty based on labor markets, households, and welfare states and analyzes the 4-11 waves of the Korean Welfare Panel Study during 2008-15. Previous studies on in-work poverty have focused on the definitions and concepts of in-work poverty by analyzing employment and unemployment persistence and repetition dynamics, but rarely paid attention to institutional distributive performance. In this regard, this study preforms a stepwise analysis of labor markets, households, and welfare states as a process of income generation in labor markets, satisfaction of welfare needs and income pooling at households, and deduction of social security contribution and income tax as well as receipt of public transfer income at welfare states. Results of empirical analysis show that in-work poverty had been on increase during 2008-11, followed by a decrease between 2012-15. At labor market stages, full time status had the most prominent impact on in-work poverty process, while status by employment and contract type have generated a huge variation as well. At household stages, household work intensity and number of earners contributed to reduction of in-work poverty, but the relations did not seen to be straightforward. However, welfare state played little role in lifting employees out of in-work poverty. In terms of institutional distributive process, in-work poverty was prevalent in either household-welfare state stage or labor market-household-welfare stage. Non-vulnerable group in terms of in-risk poverty was around 80% of the sample during the period of analysis, the size of which has remained constant.

The purpose of this study is to investigate the characteristics of the elderly with disability focused on comparison between aging with disability and disability with aging in Korea. Disability in older age has been related to several psychosocial characteristics, including social support, self-esteem, life satisfaction and depression. However, the exact role of these characteristics in the disablement process remains uncertain and this study focused on comparison between aging with disability and disability with aging in Korea. This study analyzed the 12th wave (2017) KWPS(Korean Welfare Panel Study)and Disability Study which included 692 elderly with disability aged 65 and over. The data were processed by SEM and multi-group SEM analysis. The findings were as follows; First, family support and the significant others support showed direct effects on the life satisfaction of the elderly with disability. Second, family support and the significant others support reduced the level of depression and enhanced self-esteem and finally impact on the life satisfaction of the elderly with disability. The formal support enhanced the depression and reduced self-esteem and eventually reduced the life satisfaction. Third, the disability with aging group showed more higher perception and more experience of formal support and formal service and more higher depression than the aging with disability group. Forth, the significant others support on life satisfaction only showed significance in disability with aging group and depression had significance in disability with aging group. Finally, aging with disability group showed positive effects on the formal support of life satisfaction but showed negative effects on the depression and self-esteem. Based on these findings, practical implications of future directions for research are discussed.

The present study examines the development of self-esteem from young adulthood to old age, as well as predictors of change in self-esteem over time. The eight waves of Korean Welfare Panel Data(KOWEPS) were used for analyses, and a nationally representative sample of 15,511 individual aged 19 years and above were included. The multilevel growth curve model was specified to address the research questions. The result shows that the self-esteem trajectory differed across different age groups with those in early adulthood and adulthood showed an increasing linear trajectories while the old age showed a declining slope. Furthermore, predictors of changes in self-esteem also differed across the age groups that while depression and relationship variables were constant in predicting self-esteem change for all three age groups, some variables such as marital status, poverty status, and employment status predicted individuals in certain age groups. Such results demonstrate the need to understand and examine the change in self-esteem at the individual level.

In order to improve the functional properties of kochujang, garic porridge was added to traditional kochujang during manufacturing. Changes in physiochemical properties of kochujang by garic porridge addition were then investigated. No big differences in general chemical compositions was observed between three kinds of kochujangs tested in this study, general kochujang purchased from a market (GK), kochujang added with raw garlic (RGK) and kochujang added with garlic porridge (GPK). However, GPK showed higher level of antioxidant and anticancer activities than those of others. The methanolic extract of GPK showed 66.38% of DPPH radical scavenging activity, while the extracts of GK and RGK exhibited 38.44% and 50.97%, respectively. Also, the effects of three different extracts of kochujangs on cell proliferation of stomach cancer cell (MKN 45), colon cancer cell (HCT116), and lung cancer cell (NCI-H460) were investigated using MTT assay. All of three extracts exhibited the highest anti-proliferative activity against stomach cancer cell, even though the proliferation of colon cancer cell and lung cancer cell were also inhibited. Among them, the extract of GPK showed the highest anti-proliferative activity (62.35%) against stomach cancer cell. From the results obtained in the present study, we concluded that the antioxidant and anticancer activity of GPK mainly originated from garlic because GPK was consisted of 23% garlic (w/w) compared to 10% (w/w) of RGK.
