This paper analyzes job sequences of men and women using optimal matching in order to find patterns of intra-generational mobility in Korean society. Men and women differ in their job careers: men show long-lasting job sequences with few gaps, while women either have short careers or have interrupted careers with long gaps. Long gaps in men's career are limited to those cases in which men move from agricultural to other job. The results from a combination of optimal matching and cluster analysis show that men's job sequences cluster around major occupations while women's cluster in terms of sequence length. The interrupted careers characteristic of women are considered to be consequent on the burdens of house keeping and child raising together with the discrimination against women pursuing careers.

China's rapid economic growth and accelerated urbanization have significantly increased labor force mobility. The choice of city residence and long-term residence intentions of migrants will have significant consequences on both economic output and societal dynamics. This paper investigates the impact of air quality on the long-term residence intention of migrants. By matching an individual-level survey on willingness to stay in the long run and the city-level air quality, represented by PM2.5, we find that the willingness to stay in the long run increases with better air quality. This implies that public policy to maintain good air quality is crucial in keeping those who moved to the city.

This study examines the job changes and the coincidence of job and major In the case of the youth, science and engineering graduates in Korea. The pattern of job changes and the coincidence of job and major get observed in the Unemployment Insurance Database and the Graduate List. This data enables us tracing all job changes in the labor market, and analysing the coincidence of job and major. The average rate of coincidence is not so high, the rate at first job is roughly one third. The youth with coincidence of job and major have earned less income than the youth without coincidence of job and major. But this result is impressive in the lower wage earners, any differences in regard to coincidence is not found in the upper wage earners. The probability of the coincidence of job and major is higher in case of the high wage and the high study attainments. The results suggests that the problem of the science and engineering graduates should be concentrated only on the lower manpower in the scientist and engineer jobs. Korean government have to lessen the number of entry into the science and engineering college and enlarge the number of entry into the science and engineering graduate school. Korean government have to prepare the system that aids establishment where the employee with coincidence of job and major earns more income.

In the studies on residential move, there has been tendency of dichotomy where short distance moves are largely caused by housing to adjust to changes in households while long distance moves are induced by shift in labor market. However, some empirical studies have proven that residential move is so complex process that the simple dichotomy should be elaborated. In this sense, the present study seeks to identify compounded course of residential move in Korea. In determining migration history, families with younger householders, renters, householders with higher educational attainment and smaller households show a higher probability to move. In case of mobility, women were more prone to move compared to man. Women compared to man, older age augmented the probability to own a house after migration. Families with householders following an occupation of sales and technical service showed lowest tendency to own houses while it marked the highest in the group of professionals. Higher land price of a region was negatively related to owning houses after migration. The present study revealed that factors in macro level as well as micro level significantly affect the move of individuals with varying effects in accordance with migration history.

In this paper, a smart home service robot McBot II is newly developed in much more practical and intelligent system than McBot I which we had developed a few years ago. Thus far, vacuum-cleaners have lightened the burden of household chores but the operational labor that vacuum-cleaners entail has been very severe. Recently, a cleaning robot was commercialized to solve but it also was not successful because it still had the problem of mess-cleanup, which pertained to the clean-up of large trash and the arrangement of newspapers, clothes, etc. Hence, we develop a new home mess-cleanup robot McBot II to completely overcome this problem on real environments. The mechanical design and the basic control of McBot II, which performs mess-cleanup function etc. in house, is actually focused in this paper. McBot II is mechanically modeled in the same method that the human works in door by using the waist and the hands. The big-ranged vertical lift and the shoulder joints to be able to forward move are mechanically designed for the operating function as the human's waist when the robot works. The mobility of McBot II is designed in the holonomic mobile robot for the collision avoidance of obstacle and the high speed navigation on the small area in door. Finally, good performance of McBot II, which has been optimally desinged, is confirmed through the experimental results for the control of the robotic body, mobility, arms and hands in this paper.

Modern methods of regulating migration processes in EU states include a wide variety of adapted, transformed under the sway of globalization tools in order to influence the movement of human capital within the European space. The main purpose of the regulatory policy on migration flows is the redistribution of professionally competent professionals between different spheres of life. Herewith, the determining factor in the effectiveness of such distribution is a rational combination of stimulating and disincentive levers of influence on the movement of citizens of different EU countries and taking into account the motives of such mobility. Modernization of migration management approaches can be a major economic, social, political and cultural progress of European countries. The purpose of the research is to conduct a detailed analysis of existing practices of migration flow management, in particular their stimulation or containment, and to outline key migration trends formed under the influence of multicomponent approaches to migration regulation, transformation of regulatory legislation and changing priorities of modern society. The research methods: statistical-analytical method; ARIS method; method of tabular, graphical and analytical modeling; comparative analysis; systematization, generalization. Results. Current pan-European methods of regulating migration processes are insufficiently adapted to the multinational socialeconomic space; consequently, there are some disparities in the distribution of migrants between EU countries, although the overall dynamics of migration is positive. Fluctuations in the population of European countries during 2000-2019 and trends in the transformation of social-economic space confirm the insufficient level of influence of current methods of regulating migration flows. Along with this, the presence of a characteristic asymmetry in the distribution of migrants requires a greater focus on the modernization of regulatory instruments, in particular, the regulatory mechanism for managing migration processes. As a result of the conducted study, further prospects for the implementation of alternative methods of regulating migration processes in EU states have been outlined; the current and projected limits for increasing the level of observance of migrants' rights at the European level have been clarified through the adoption of appropriate regulatory acts; effective solutions for intensifying the influx of high-quality labor resources from different countries to EU have been identified. The research results can be used to study methods of regulating migration processes in the countries in the global dimension.

The study analyzes divorce rates in Korea and makes suggestions for the future research of divorce rates. Based on the data from Korea Statistical Information System (KOSIS) of the National Statistics Organization, trends for divorce rates change and the relations between divorce rates and macro environmental factors are analyzed. Macro environmental factors include socioeconomic factors such as, Korean War, Vietnam War, oil shock, IMP economic crisis and gross national income (GNI), whereas demographical factors include population structure, rates of female labor participation, and geographical location. The principle characteristics of divorce rates are as follows: 1) the Crude divorce rates (CDR) and the number of divorced had been increased from 1970 to 2004, then the trend changed to a decrease; 2) the slope of the change were the highest during 1998 to 2004 after the IMP economic crisis. The relations between socioeconomic factors are as follows: 1) during the war there was a small increase of CDR for a short period of time; 2) the economic crisis of the nation tend to increase the CDR, while the IMP economic crisis had a strong impact on an increase of CDR because of the interaction effect among the population structure, women's sex role changes as well as the level of standard of living. The increase in CDR from 1990 to 2000 can be explained partly by the population of baby Boomers passing through their marriage and divorce process. The number of population residing in the rural area and the middle class households, and the mobility of population also had an impact on the divorce rates changes. The recommendations for the future research were as follows: 1) the need to develop new divorce statistics that are based on a marriage cohort or a birth cohort because family behavior is a mixture of personal, social and political responses, and because CDR is not an accurate measure of divorce rate since it was influenced by population structure; 2) the need to include micro personal factors as well as macro social factors in a model to find an interaction effect between those variables.

This paper examines the impact of internal migration on wage growth among college graduates using Propensity Score Matching methods. We define migration as moving between Seoul Metropolitan Area (SMA) and non-SMA based on the locations of graduates' first and second jobs. We also take the direction of migration into account for examining the wage premium in SMA. In order to estimate the impact of migration on wage growth, we use the Graduate Occupational Mobility Survey (2010GOMS) coupled with other supplementary data such as College Scholastic Ability Test score and local characteristic variables. The results reveals that graduates moving from SMA to non-SMA do not experience significant wage growth. However, we find that graduates moving from non-SMA to SMA experience an increase in their monthly wage about 170,000~186,000 KRW on average (9.5~10.3% of their monthly wage on the first job).

The purpose of this study, reflecting the characteristics of recent R&D activities, where knowledge convergence and exchange and the growth of researchers are becoming more important, is to promote the growth of outstanding researchers by establishing a support system for researcher career development (intensifying expertise) and career fluidity (change in core research topics). Using the results of a survey of 548 researchers from government-funded research institutes, this study analyze environmental factors of research that promotes career development suitable for the growth of researchers after quantitatively verifying the effects of career development and career mobility on research outcomes. As a result of the analysis, it is more desirable to strengthen career liquidity after stable career development, but the human resources and career development support systems of research institutes are insufficient. Therefore, in this study, policy measures to support researcher career development and liquidity were proposed in four stages.

The paper is basically attempted to reveal the factor price equalization(FPE) on Korea, United States, and Japan by the ARDL-bounds testing. Wage-rental ratio and relative commodity prices between Korea, United States, and Japan are analyzed by employing equality and convergence frameworks. Empirical evidences are shown that necessary and sufficient conditions for the FPE seems to be easily satisfied in a small country such as Korea rather than large ones as like United States and Japan. And, the FPE is more easily achieved by a nominal term rather than the real term. Due to the fact that an error correction term in the Error Correction Model is insignificant, direct mobility of labor and capital between the countries is not that effective to a short run adjustment. It implies that the FPE is in general going through a long run path. It also has to be mentioned that a trade policy has to selectively implemented depending on the weight of trading volumes and it has to be build up by a long run basis.
