Article I: "Analysis of Changes in Life Satisfaction and Influence Factors in Single-Person Households of Middle-Aged and Elderly People: Comparative Analysis of Middle-Aged and Elderly People with Multi-Person Households," Hong Sungpyo, Catholic University of Korea & Lim Hanryeo, Seoul National University

The purpose of this study was to suggest a policy direction for middle-aged and elderly single-person households by comparing and analyzing changes in life satisfaction and factors influencing them with those of multi-person households. For the study, data from the Korea Welfare Panel (12th~15th waves) were used, and 1,378 single-person households and 6,382 multi-person households were analyzed for middle-aged and elderly adults over 40 years of age. By using a latent growth model, we analyzed the factors affecting the change in life satisfaction, the intercept, and slope of single-person households and multi-person households of middle-aged and elderly people.

The main conclusions drawn from the study are as follows. First, the life satisfaction of middle-aged and elderly people tended to decrease regardless of single-person and multi-person households, but the level of life satisfaction of single-person households was relatively low. Second, income and self-esteem were common variables that had a significant effect on life satisfaction of middle-aged and elderly people, and in particular, self-esteem had an effect on the intercept and slope of life satisfaction. Third, middle-aged people showed a lower level of life satisfaction than the elderly, and in particular, it was confirmed that middle-aged single-person households had a greater negative effect on life satisfaction than multi-person households. Fourth, education level, participation of volunteer and labor activity were significant variables to increase life satisfaction for middle-aged and elderly people in multi-person households, but no significant effect could be confirmed for single-person households.

The implications drawn from the findings are as follows. First, increased support is needed to improve the quality of life of single-person households of middle-aged and elderly people. Second, support is needed in connection with self-esteem and psychological recovery of single-person households of middle-aged and elderly people.

Article II: "An Analysis of Media Coverage and Frame of the 2020 Doctors Strike 

Media coverage tends to influence public acceptance and interpretation of information. In this case, the ideological nature of the media can influence policy decisions by representing stakeholders’ positions or forming public opinion favorable to them. This study classified newspaper media by ideological tendency and analyzed the patterns and frames of reporting of the 2020 doctors strike. The analysis period is from June 28, 2020, when the Korean Medical Association first mentioned the strike, to September 4, 2020, when an agreement was signed with the government. The subject of analysis consisted of 493 articles from the Chosun-Ilbo, Donga-Ilbo, Hankyoreh, and Kyunghyang-Shinmun that were searched through BigKinds of the Korea Press Foundation during the period. The analysis method is content and frame analysis according to article type, coverage type, information source type and ideological tendency. The findings of quantitative analysis showed that the ratio of case-focused and direct coverage was high in both conservative and progressive media in the article type and the coverage type (P<0.001). However, there was a difference in the types of information sources used in the articles according to the ideological tendencies of the media (P<0.001), and the frames used in the editorials were also different (P<0.05). The qualitative analysis suggests that conservative media mainly emphasized the government’s responsibility in policy promotion through the cause attribution frame, but progressive media criticized the act of of the Medical Association as unethical through the public and moral evaluation frame. The framing methods of the media may be different depending on the ideological tendency. However, if it is expanded and reproduced, it may cause public confusion about health care policies and may ultimately hinder the improvement and development of the health care system. Therefore, it is necessary to actively pay attention to agenda setting and conflict management surrounding public health policy. 

Article III: "A Study for Developing a Curriculum for Service Providers Assisting Women in Pregnancy Crisis," Lee Sun Hae, Chung-Ang University; Park Jihye, Chung-Ang University; Kim Jihye, Hyupsung University; Cho Sunghui, Seoul Theological University

A comprehensive system of integrated and accessible services is called for to support women experiencing a troubled and unintended pregnancy. The purpose of the study was to develop a counseling curriculum to train service providers who can offer unbiased information and counseling services to women in pregnancy crisis. Following an extensive review of the literature on the tasks, competencies, and various training requirements concerning such services, the authors developed the first draft of the curriculum. This was modified two rounds of Delphi survey. The final version was a 100-hour program with 36 subjects that address 7 competencies in three areas (basic, advanced, and practice). The authors suggest establishing an integrated system of care for women in pregnancy crises, continuing education for quality control of both personnel and services, and a supervision system. 

Article IV: "How Did the Accumulation of Private Assets in Korean Soceity Affect the Welfare Perception Structure?: Focusing on the Relationship between Attitudes toward Insurance Function, Redistribution and Tax Increases," Yang Jongmin, Seoul National University

The purpose of this study is to investigate the relationship between attitudes toward social insurance, redistribution, and tax increase and to classify them into several types. In addition, this study tried to investigate how income, assets, and debts, which have served as functional substitutes for public welfare in Korean society, had an effect on this welfare perception structure. The analysis results are summarized as follows. First of all, as a result of Latent Class Analysis, the welfare perception structure related to social insurance, redistribution, and tax increase can be broadly classified into three types: ‘in favor of social insurance, the redistribution, and tax increase’, ‘against social insurance and tax increase, in favor of the redistribution’ and ‘neither in favor of nor against social insurance and tax increase, in favor of the redistribution’. Concerning a result of multinomial logistic regression analysis to find out the variables that have a significant effect on the probability of belonging to the three latent groups, as income and assets increase, the probability of falling under the group, ‘against social insurance and tax increase, in favor of the redistribution’ increases. Regarding debts, as the debt-to-asset ratio increases, the probability of falling into the group, ‘in favor of social insurance, the redistribution, and tax increase’ increases. These analysis results show that, considering the policy environment at the time the analytical data was created, there was no risk of an economic crisis or a drop in real estate prices, and social risks had to be dealt with at the individual and family level in a situation where the role of public welfare was still limited. It can be interpreted that preference for the role of the state as a welfare provider varies according to the level of asset accumulation. 

Article V: "A Validation Study of the Korean Version of the CASP-16," Choi Myungjin & Kim Giyeon, Chung-Ang University

The aim of this study is to validate and test the psychometric properties of the Korean version of the Quality of Life in Old Age (CASP-19) developed by Hyde, Wiggins, Higgs, and Blane (2003). A total of 345 respondents aged 55 years and older were selected by an online survey and the sample was divided in half at random to perform exploratory and confirmatory factor analysis. Results from the exploratory factor analysis revealed that the Korean version of the CASP-16 (K-CASP-16) were divided into four domains (‘control’, ‘autonomy’, ‘pleasure’ and ‘self-relization’), which was consistent with the original version. In the confirmatory factor analysis, a second-order four domains model showed a good overall fit of K-CASP-16. The K-CASP-16 correlated with Satisfaction With Life Scale (r=.735) and showed an adequate internal consistency (α=.882). The results of this current study indicate that the K-CASP-16 is a reliable and valid scale. Finally, the significance, clinical implications, limitations of this study were discussed in relation with future studies. 

Article VI: "The Effects of COVID-19 on the Mental Health of the Disabled," Kim Yire, National Disaster Management Research Institute & Nam Jaehyun, Pusan National University

We examined the effects of COVID-19 on the mental health outcomes (e.g., depression and self-esteem) of the disabled. For analysis we the difference-indifferences approach with multiple treatments using data from the 14th and 15th waves of the Korean Welfare Panel Study (KoWePS). The observations consisted of 21,049 individuals of whom 18,987 were non-disabled, 648 were severely disabled, and 1,414 were mildly disabled. We further conducted subgroup analyses of the degree of disability, the type of disability, gender, and age. The main findings are as follows. First, COVID-19 had little effect on the degree of depression in people with disabilities, but it did affect non-disabled people, though without statistical significance. Second, COVID-19 has statistically significantly influenced self-esteem for people with disabilities. Third, the effects of COVID-19 varied according to the degree of disability. It led to reduced self-esteem in persons with mild disability. Furthermore, we found that self-esteem declined in the physically disabled and those with impairments external bodily functions after COVID-19. In addition, the of effects COVID-19 were more pronounced in the male group and in persons with disabilities under age 65. Our findings indicate that COVID-19 has disproportionately affected people of different physical characteristics, and provide some policy implications for people with disabilities. 

Article VII: "Exploratory Research on Happiness Trajectory and Related Factors: Exploring Disability and Veenhoven's Discussion," Park Jongeun, Seoul National University

This study started with the question of ‘Is happiness really declining in Koreans?’ To this end, the trajectory of adult happiness was estimated using data from the Korean Welfare Panel and the influencing factors were examined. In addition, given that Korea is a country that ratified the UN Convention on the Rights of Persons with Disabilities, the trajectory and factors influencing happiness were explored according to disabilities. The subjects of the analysis were 11,844 adults aged 19 or older who participated in the Korean Welfare Panel Survey. The happiness trajectory, a dependent variable, was built using the subjective happiness index measured every year for four years from 2017 to 2020. The predictors of the happiness trajectory used variables as of 2017, the starting point. This study controlled for socio-demographic variables (age, gender, education, income, and with or without spouse), and used, following Veenhoven’s discussion, individual system variables (subjective health status and self-esteem) and social system variables (social relationship satisfaction and the National Basic Livelihood Security Program) as exogenous variables. On average the happiness trajectory showed an increase with time. Also, all the predicted factors, with the exception of the National Basic Livelihood Security Program, had a significant positive effect on the happiness trajectory. There were significant differences in the happiness trajectory between people with a disability and those without. But there was no difference between the two groups in the predictive factors. Based on these research results, implications and follow-up studies were discussed to promote happiness of the entire population and the disabled population. 

Article VIII: "An Exploratory Analysis of Unmet Healthcare Needs among Patients with Rare Diseases and Their Caregivers," Choi Eun Jin, Park Sylvia, Chae Su Mi, Weng Yue ru, Kang Hae Li, and Moon Seok Jun, KIHASA

This study was aimed at investigating unmet healthcare needs among rare diseases patients and their caregivers. An online survey was conducted of rare disease patients and their caregivers. A total of 456 responses was collected and analyzed. The respondents included 185 patients and 271 caregivers. They reported a total of 155 rare diseases. The prevalence of disability was 20.5% in the patient respondents, while the caregiver respondents reported a 66.1% disability prevalence for their rare disease patients. This study used quality of life as the dependent variable. The independent variables include demographic and socioeconomic variables, w/o disabled, education, household income, economic activity, medical use and unmet needs questions. We used such statistical methods as correlation, analysis of variance, and regression analysis. Most of the caregivers were parents of children with rare diseases who, lacking adequate supportive information, spent much money to get rehabilitation service. Economic activities such as engaging in full time or part time jobs, were positively associated with increased quality of life and this was statistically significant for both the patients and caregivers. There should be increased support for inclusive care for the patients and the family members with regard to economic support. Patient and caregivers need more support to get information and opportunities for treatment. 

Article IX: "Systematic Review on the Evaluation Research of Drug Utilization Review (DUR)," Kim Jinyi, Hanyang University; Hong Ji-Yoon, Health Insurance Research Institute; Son Heejung, Patient-Centered Clinical Research Coordinating Center; and Shin Young-jeon, Hanyang University

The Drug Utilization Review (DUR) has been operating nationwide since 2010. Although some DUR related studies and policy evaluations have been conducted, it is necessary to evaluate DUR comprehensively. This study systematically reviewed the existing domestic DUR evaluation studies. 31 articles were selected by searching documents published up to March 2021. The first DUR evaluation article in Korea was a study on the perception of DUR in 2009. The number of studies increased until 2018 after the system was implemented. There were a survey (2019) and a study (2020) seeking to add a feedback function of DUR. The existing DUR evaluation article was 21 positive (58.3%) and 15 negative (41.7%). There were 21 articles for effectiveness (58.3%), 6 articles for satisfaction (16.7%), 5 articles for feedback (13.9%), and 4 articles for convenience (11.1%) in order. In the effectiveness section, there were 18 positive articles (85.7%) and 3 negative articles (14.3%). In the satisfaction study, doctors and pharmacists regarded DUR as positive for its effectiveness (50%), but the demand for improved convenience and feedback was high (50%). In the feedback study, all 5 studies (100%) were evaluated negatively. All 4 studies (100%) in the convenience section were evaluated negatively. Through a systematic analysis of the existing DUR evaluation research, the currently implemented DUR policy is evaluated positively in the utility area, but policy improvement is needed in the convenience and feedback areas due to negative evaluation. In the future, conducting DUR effectiveness evaluation through patient health outcome research, improving the quality of DUR criteria items, improving feedback through the use of DUR monitoring, and improving the convenience of DUR alarm grading can increase the effectiveness of DUR policy. In the future, conducting DUR utility evaluation through patient health outcome research, improving the quality of inspection criteria items, improving reflux through the use of DUR monitoring, and improving the convenience of DUR alarm grading can increase the impact of DUR policy. 

Article X: "Analysis of Factors Influencing the Implementation of a Work-Family Balance System in Companies," Bhang Jin-ah & Hur Soonim, University of Seoul

Flexible working hours is a policy tool for work-family balance that supports workers to secure time to raise children while maintaining their work life. The purpose of this study is to analyze the factors influencing the introduction and use of flexible working hours in companies, and to obtain implications for policy effectiveness through comparative analysis with the reduction of working hours during childcare. To this end, the characteristics of company, HR management, and organizational culture were analyzed as major influencing factors. For the analysis data, the 7th Female Managers Panel Survey (2018) was used, and statistical analysis was conducted for a total of 346 companies. As a result of the analysis, public sector institutions, the presence of a union, the proportion of highly educated women, and transparent HR management were significant in the implementation of flexible working hours, a corporate autonomous system. On the other hand, in the case of reduction of working hours during childcare, which is a legally mandatory system, the size of the company, whether there is a difference in promotion due to gender discrimination practices, and the perception of the CEO were significant. In particular, the results of this study, which confirmed that rational HR management is an important factor in the implementation of both systems, suggests that policy effectiveness can only be enhanced when HR management improvement in the aspect of work-family balance is accompanied. 

Article XI: "A Longitudinal Study of Changes in Depression Level in Parents of Households with Children after COVID-19: Focusing on Poverty," Noh Hye-Jin, Gangseo University

This study verified the trajectory of changes in depression level in parents of households with children before and after COVID-19. The results of the study are as follows. The trajectory revealed that the depression level in parents of households with children increased significantly in the four years from 2017 to 2020. Second, at the inception of depression, it was found that depression levels were higher in parents with lower income. On the other hand, higher the self-esteem, marital satisfaction, education level, and the age of the youngest child, the lower the lower the level of initial depressive symptoms. Third, parents in poor families had a faster increase in the level depressive symptoms, and higher education levels were found to have slowed increases in depressive symptoms. In situations where self-esteem and marital satisfaction were not controlled, being in work was associated with higher initial depression levels and a higher slope of increase in depressive symptoms. Fourth, the effect of being in work on the increase in depressive symptoms was significant only in men. On the other hand, the effect of the youngest child’s age on the lowering of depressive symptoms at their inception was significant only for women. Based on these results, this study proposed the establishment of an income support system centered on poor households, a regular operation of a public care system, and an emergency care system as strategies to alleviate disaster inequality. 

Article XII: "The Impact of Social Capital and Self-Esteem on the Quality of Life of the Young Unemployed," Lee Nakyung, Seoul National University

The youth unemployment rate in Korea driven by prolonged economic stagnation has been steadily rising, threatening the quality of life of the young people. In searching for the alternatives this study explores the roles of self-esteem and social capital in terms of trust, generalized reciprocity, and social network. While considering the perceptual impacts that are bestowed on the individuals through the status of being employed, this study examines each difference in social capital and self-esteem respectively, among the individuals between groups of the young employed and the young unemployed, aged 19 to 38 at the time of the survey in 2018. It further examines the mediating effect of self-esteem in the relationship between social capital and the quality of life of the young unemployed. By conducting t-test, Baron & Kenny's mediating effect analysis and Sobel test, first, statistically significant differences in social network and self-esteem between the young unemployed and the young employed were found. Second, the mediating effects of self-esteem in the relationship between all three components of social capital and the quality of life were observed. The results of this study indicate the need for the systematic alternatives to sense of alienation and loss of identity experienced by the young unemployed as their connection with society is structurally being put at stake. 

Article XIII: "The Relationship between the Experience of Being Discriminated against, Economic Difficulties, and Job Burnout in Non-Regular Workers: The Mediating Effect of Satisfaction with Decent Work and Job Autonomy," Kim Min Sun, Dankook University

In this study, a research model was established assuming the mediating effect of decent work and job autonomy in the relationship between having been discriminated against, economic difficulties, and job burnout in non-regular workers, and the fit of the model and the influence of individual variables were examined. To this end, in this study, data were collected from 199 young adults in non-regular employment and the model was analyzed through structural equations. SPSS20.0 and AMOS20.0 programs were used for data analysis. This study found that the research model appropriately explained the data on the young people. Looking at the path coefficient, it was found that all paths were significant except for decent jobs and direct routes to job burnout in economic difficulties. The indirect effect of decent job and autonomy satisfaction was significant in the relationship between having been discriminated against and job burnout, and the indirect path from economic difficulties to decent job and autonomy satisfaction was also significant. Based on these findings, this study discussed measures to prevent job burnout of non-regular workers and to lower emotional difficulties due to economic difficulties or being discriminated against. 

Article XIV: "The Age-Friendly Community Environment Factors Contributing to Life Satisfaction of Older Adults Living Alone," Lee Hyunmin, University of Seoul & Choi Mi Sun, Silla University 

The purpose of this study was to identify the factors in the community environment which affect the life satisfaction of the growing number of older individuals living in single-person households. The raw data from the 2020 National Survey of Older Koreans was utilized and responses of 3,112 older adult single-person households were investigated. Hierarchical regression analysis was performed by distinguishing the community environments into three categories of World Health Organization’s age-friendly environments: physical, social, and service environments. The results showed that the perception of the physical environment (housing, living facilities, and space) was positively associated with life satisfaction among older adults living alone. Second, the social environment (social involvement, neighbor interaction, respect for older individuals, and political activity) was positively related to life satisfaction. Third, perceived service environment (difficulty utilizing service) was negatively related to life satisfaction. Based on the findings, we proposed practical and policy suggestions for enhancing life satisfaction of single-person older adult households. 

Article XV: "Factors Influencing the Depression of Sexually-Assaulted Female Foreign Students: A Comparison of Influencing Factors between Groups Seeking and Not Seeking Formal Help," Chung Se-mi, Yeoju Institute of Technology & Kim Eun Jeoung, Hanyang Womens University 

The purpose of this study is to examine factors affecting depression in foreign female students affected by sexual violence and to prepare an intervention plan for keeping them safe from sexual violence. We used data from the 2020 Survey on the Safety and Human Rights Protection of Female Foreign Students. Among a total of 410 emale international students, data on 191 respondents who had experienced sexual violence were analyzed. The subjects were then divided into those who had sought formal help (n=62) and those who had not (n=129). Our analysis showed no statistical difference in the level of depression between the two groups, but the former group showed significantly higher levels of “social support” and “satisfaction with studying abroad”. Another finding is that “social support” and the “level of Korean proficiency” were factors affecting depression in the group that had sought formal help. Factors that were found to affect depression in the other group were “secondary damage”, “the satisfaction with studying abroad”, and the “country of origin”. Based on its findings, this study suggested policy and practical interventions for keeping foreign female students safe from sexual violence and for making support services more accessible to them.

Article XVI: "A Study on the Effect of Healthcare Provider Competition on Intensity of Care under a Fixed Price Structure," Yoo Hyerim, Health Insurance Review and Assessment Service & Min Insik, Kyunghee University

The analysis of competition among healthcare providers is important in measuring the effects of competition mechanisms at the market level and national medical expenses and medical resource distribution at the national level. This study aims to provide both theoretical and empirical evidence of the effect of healthcare provider competition under the fixed price. This study investigates a theoretical model of healthcare provider competition using the circular city model (Salop, 1979). A proposition derived as a result is, the intensity of care increases with the number of providers. Empirical work examines the theoretical results of the theoretical framework. The impact of provider competition on the intensity of care is investigated by a panel random effect model using NHIS (National Health Insurance Service)-cohort 2.0 DB data based on National Health Insurance claims data. The estimated results show that the proposition is supported empirically as the intensity of care increased with the number of providers. 

Article XVII: "The Definition and Types of Food Crisis as Seen from the Perspective of the Food System," Kim Seong-Ah, The Seould Institute; Seo Da-ram, Korea University; Kim Sang-Hyo, Korea Rural Economic Institute; and Kim Kirang, Dankook University

This study was aimed at defining and classifying food crises in a way suitable for the situation in Korea. This study also examined potential disaster situations that may well lead to food crisis and suggested ways to keep the food security system working well even in a possible disaster situation. Through literature review, we surveyed types of food crises that can occur at each stage of the food system (supply, distribution, consumption), and then we examined the types of food crises that can be relevant to the domestic situation. Based on the findings of this study, we defined food crisis in terms of food insecurity. Food crisis was classified into four types, including food supply crisis, food distribution crisis, food consumption crisis, and food safety crisis. In addition, this study presented potential food crises that may occur due to a future natural or social disaster. Food crises are prominently revealed in disasters or corresponding national crises. In order for the food security system, which has been gradually working towards the ‘zero food crisis’, to respond timely to a sudden crisis, it is necessary to actively prepare for the food crises as presented in this study. 

Article XVIII: "The Effect of Private Health Insurance on Healthcare Utilization: Evidence from the Korea Health Panel," Song Yunah, Korea Insurance Research Institute

This article examines the causal effect of private health insurance on the utilization of health care services using the Korea Health Panel from 2014 and 2018. To control for self-selection bias, it employs the latent factor structure consisting of a discrete choice module for health insurance plans (uninsured, fixed-benefit, indemnity, fixed-benefit plus indemnity) and an outcome equation with count dependent variable measuring utilization. The results indicate that both the indemnity type and the fixed-benefit plus indemnity type increased physician visits, and the length of hospital stay increased in the fixed-benefit plus indemnity type. There was positive insurance effect on health care utilization at the lowest income level, which suggests that private insurance deepens economic inequalities in health care utilization. Also, private health insurance is found to increase physician visits for regular wage workers and the length of hospital stay for self-employed workers. In addition, the positive insurance effect on health care utilization is more pronounced in individuals below the age of 50. 

Article XIX: "A Systematic Review of Life Expectancy and Healthy Life Expectancy of Persons with Disabilities," Kim Jung Ae, Kyungmin University; Hwang Ji Won, Kyungdong University; Choi Yong-jun, Hallym University; and Choi Kyung-Hwa, Dankook University

This study aimed to systematically review the literature estimating the life expectancy and healthy life expectancy of persons with disabilities to identify gaps compared to the non-disability persons in health. Twelve articles were selected after reviewing papers (Published for Jan. 01. 2000-Mar. 31. 2021) searching for Korean studies on Google Scholar, RISS, National Assembly Digital Library, and literature in English on the Web of Science and PubMed. Among the articles, four included persons with all kinds of disabilities, eight included those defined as disabled persons and then compared with the non-disability persons or the general population, and five assessed among the disabilities by the severity. Persons with disabilities had a shorter life expectancy and healthy life expectancy than those without disabilities or the general population; people with severe disabilities had a shorter life expectancy than those with mild disabilities; gaps for healthy life expectancy were bigger than those in life expectancy. Further, it is necessary to delineate the differences in life expectancy and healthy life expectancy between persons with and without disabilities according to the severity and type of disability and sociodemographic levels such as sex, educational attainment, income, and occupation of the persons with disabilities. Policies should be established that reduces the current gap, and the life expectancy and healthy life expectancy of persons with disabilities should be regularly estimated to monitor the effect of healthcare policies. 

Article XX: "The Effects of Relative Deprivation of Youth on Suicide: The Serial Mediation Effect of Prospects and Social Isolation," Lee Soo-Bi, Shin Yerim, and Yoon Myeong-Sook, Jeonbuk National University

The purpose of this study was to verify the serial mediation effects of prospects and social isolation in the relationship between relative deprivation and suicide of youth. For achieving this purpose, an on-line survey was conducted using questionnaire, based on quota sampling of youth 19~39 years old. Total 521 subjects were tested by using PROGRESS macro 4.0. Following were verified as the results of this study. First, relative deprivation had a significant effect on suicide of the youth. Second, relative deprivation had a negative effect on prospects and social isolation. Finally, as for the medication effects, prospects and social isolation had a significantly negative mediation effects in the relationship between relative deprivation and suicide of the youth. Based on these results, the present study discussed practical suggestions to improve effective suicide prevention services for youth. 

Article XXI: "Childcare Arrangements of 3-to 6-year-old Children and Associated Factors before and during COVID-19 using Latent Class Analysis," Choi Jieun, Yonsei University & An Mi Young, Kookmin University

This article examines childcare arrangements of 3-to 6-year-old children and factors associated before and during Covid-19 in Korea. We analyzed Korean Longitudinal Survey of Women and Families 6th (2016-2017), 7th (2018-2019), 8th (2020-2021) waves, focusing on care by grandparents, nurseries, kindergartens, and classes at Hakwon and personal tutoring. Latent class analysis results show that there are not much differences in childcare arrangements before and during the Covid-19 in terms of what the families used. In all waves nursery-centered arrangement accounted for between 45% and 52% and kindergarten centered 39-47%, with the rest utilized more shadow education. But it is important to note that during Covid-19, the kindergarten-centered arrangement used more shadow education than before. Further, families who all utilized private classes at Hakwon as some of them used nurseries newly appeared. Low-income families continued to use childcare at nurseries during the pandemic. But higher income families relied more on shadow education, particularly the education service at hakwon.
