The purpose of this study is twofold. First, it shows how to calculate the size of nonregular workers in Korea using the supplemental surveys to the Economically Active Population Surveys. Second, it decomposes the difference in the share of nonregular workers between 2005 and 2013 by a Oaxaca-type method.. The obtained results indicate that the differences in coefficients rather than the differences in characteristics are mainly responsible for the decline in the share of nonregular workers. This implies that a worker with the same characteristics is more likely to be a regular worker in 2013 than in 2005. This tendency may come from the changes in workers's as well as firms' employment practices. Also, it is suspected that the Nonregular Worker Act enacted in 2007 may have contributed to the decrease in the share of nonregular workers.

Employment form and gender as stratification factors may generate health disparities in Korea. Previous studies have examined the existence of health disparities by employment form and gender. However, few studies examined how the health disparities can be reduced effectively. This study intends to confirm the existence of health disparities between employment-gender groups and explore the effective health resources which can reduce the possible disparities. Using a national probability sample of Korean adults collected in 2011, we attempts to test the interaction effects between employment-gender groups and health resources on self-rated health. For health resources, 24 variables of five dimensions(social relationship, psychological resource, activity factor, health behavior, and usage of medical service) are taken into account. In results, first, the health levels of the other three employment-gender groups are worse than that of male-regular workers. Second, the effective health resources which can reduce the health disparities are different across the employment-gender groups. An effective health resource for female-nonregular workers is a peaceful relationship with her children. Effective health resources for male-nonregular workers are peaceful relationships with his parents and siblings, low stress, religious activity, and exercise. An effective health resource for female-regular workers is interpersonal trust. These results imply that personal or social interventions for health of specific disadvantaged groups need to focus on specific resources which are more effective for the groups.
