Identifying the roots of inequality of opportunity in South Korea by application of algorithmic approaches

This study identifies the roots of inequality of opportunity in South Korea by applying algorithmic approaches to survey data. In contrast to extant studies, we identify the roots of inequality of opportunity by estimating the importance of variables, interpreting the estimated results, and analyzing the importance of individual variables, instead of measuring inequality of opportunity. We apply a decision tree classification algorithm, light gradient boosting machine, and SHapley Additive exPlanations to estimate the importance of the studied variables and interpret the estimated results. According to the estimated results, the region where the individuals grew up, their gender, and their father’s job during their childhood were the main factors contributing to inequality of opportunity. This study proves that the considerable regional disparity and social environment perpetuate gender inequality in South Korean society. It argues that an individual’s socio-economic achievements are strongly influenced by their father’s background, thus, outweighing other family background-related factors. Individuals receive unequal opportunities owing to a combination of region, father’s background, and their own gender, thereby, affecting their socioeconomic achievements. If these factors remain influential from birth to adulthood, removing the conditions that structure them would be one way to achieve equality of opportunity.

Virtual conference participant’s perceptions of its effectiveness and future projections

Background The virtual conference format has become an essential tool for professional development of researchers around the world since the outbreak of the COVID-19 pandemic. This study aims to identify empirical evidence of the benefits and challenges of virtual conferences by investigating participants’ experiences with them. Methods The study participants were delegates to the 40th annual meeting of the Korean Society of Nephrology, which was held virtually in September, 2020. A questionnaire was developed and implemented among the conference attendees. The 44-item questionnaire included five sub-scales related to participant perceptions of the virtual conference, which were (a) convenience and accessibility, (b) planning and organization, (c) technology use, (d) social exchanges, and (e) overall satisfaction, their preferences of conference formats, and their views of future projections for a virtual conference. Results A total of 279 delegates completed and returned the questionnaires (18.8% response rate). Participants varied in gender, age, profession, work location, and prior experience with conferences. On a four-point Likert scale (1 = “strongly disagree” and 4 = “strongly agree”), participants showed positive perceptions of the virtual conference in general, where the total mean (M) was 3.03 and less positive perceptions on social exchanges (M = 2.72). Participant perceptions of the virtual conference differed across age groups, professions, and prior experience with conferences (p < .05). Approximately half of the participants (n = 139) preferred the virtual format, and 33% (n = 92) preferred the conventional format. Participant preferences for the virtual format were somewhat evenly distributed between asynchronous (32.9%) and synchronous (29.1%) modes. Participants predicted a virtual conference would continue to be a popular delivery format after the end of the COVID-19. Conclusions Although participants had positive perceptions of the virtual conference, more support needs to be offered to those who may be less comfortable with using technology or with online interactions, and there is a need for improvement in supporting social exchange among attendees. Also, it is suggested that a blend of asynchronous and synchronous delivery methods should be considered to meet the varied needs of attendees.

Confucian Identification, Ancestral Beliefs, and Ancestral Rituals in Korea

Since Koreans do not consider Confucianism to be part of religion, conventional religious identification questions cannot accurately capture the number of Confucians in Korea. Using the Korean General Social Survey and other data sources, we aim to describe the identification, beliefs, and practices related to Confucianism, especially ancestral rituals, and to examine whether these beliefs and practices differ across religious groups. Contrasted with 0.2% of the adult population identifying their religion as Confucianism in the 2015 Korean Census, 51% considered themselves as Confucians when asked, “(Regardless of your religious affiliation) do you consider yourself a Confucian?” If we consider those who think that rites for deceased family members are Confucian, the proportion was 44%. Considering those who conduct ancestral rites at a gravesite as Confucians, the proportion was 86%, but was only 70% when we count those who perform ancestral rites at home as Confucians. We also found substantial differences among religious groups. In general, Buddhists were most likely and Protestants were least likely to identify with Confucianism, believe in the power of ancestors, and perform ancestral rites. Perhaps most telling is the result of religious none falling in the middle between Buddhists and Protestants in terms of identification, beliefs, and rituals of Confucianism. The differences of religious groups appear to reflect religious syncretism and the exclusivity of religion. It is overstating to declare a revival of Confucianism, but it is reasonable to say that Confucianism is not a dying tradition in Korean society.
