This study examined the factors influencing the health status according to class and socioeconomic class recognition by the employment type. To take advantage of the 18 original sources of the Korea Labor panel materials carried out in the South Korea Labor Institute, 5,158 adults over 20 years old were included in the final analysis. The research results revealed that the incomes of regular workers and non-regular workers between the hierarchy and socioeconomic hierarchy recognition showed a statistically significant difference between the cage; it was consistent between the hierarchy in only the "heavy" category. Regular workers of society, and regardless of non-regular workers, were analyzed to be relatively low compared to the actual income. Regression analysis showed that regular jobs had higher socioeconomic hierarchy recognition. Non-regular workers had a lower income bracket and lower socioeconomic hierarchy recognition. In particular, in the case of non-regular workers, the pension was not subscribed and they had a poorer state of health. Therefore, the pension insurance payment for non-regular workers needs to compensate for the lost income during non-employment periods. In addition, the government should improve public relations through education, management fields, and cooperation with labor.

The purpose of this study was to examine the relationship between children's self-esteem, peer attachment, parenting attitudes, and children's grit, and to specifically identify the influence of children's self-esteem, peer attachment, and parenting attitudes on children's grit. The characteristics of the survey subjects were identified through frequency analysis and descriptive statistics analysis of the 11th year of the Korea Children's Panel (2018) data, and Pearson's moment correlation coefficient was calculated for correlation analysis between major variables. Multiple regression analysis was conducted to examine the influence of children's self-esteem, peer attachment, and parenting attitudes on children's grit. The research results are as follows. First, children's self-esteem, peer attachment, and parenting attitudes were found to be positively correlated. Second, the child's self-esteem was found to have a positive influence on the child's grit, and among the peer attachment sub-variables, peer trust was found to have an influence, and among the sub-factors of parenting attitude, 'mother' affection/involvement, 'father' Democratic relationships were found to have an effect. In other words, it can be seen that children's self-esteem at the personal level, peer trust at the school level, and maternal affection and paternal relationship at the family level are useful variables that strengthen children's grit. Accordingly, in order to improve children's grit level, we must consider promotion measures through intervention and support at a multifaceted level.

This study examines how the patent results of the University Academic-Industrial Cooperation influence technology transfer. Statistical analysis was performed by using 2013 panel data from the Ministry of Education and Science Technology(MEST) National Research Foundation of Korea(NRF) and the results are as follows. The results show that the patent result factors that have a positive effect on the total number of technology transfers are domestic patent application numbers, foreign patent application numbers, future technology(6T) patent application numbers, science technology patent application numbers. The factors that have a positive effect on increasing royalty are the total number of technology transfers. Domestic patent application numbers, future technology(6T) patent application numbers and science technology patent application numbers have a positive effect on patent results. The results implicate that more research and development is needed for more patents to be applied, that the main focus should be on future technology(6T) and science technology fields, and that effort should be directed at planning negotiation strategies for the term of the contract. However, this study is the need to research, including primary research is so patent performance may be limited in having only been considered in future studies of human and material resources and operating system factors that may be presented to the essential elements of the Industry-Academic Cooperation Foundation this raises.

Korean income data obtained from Korea Labor Panel Survey shows excessive zeros, which may not be properly explained by the Tobit model. In this paper, we analyze the data using a zero-inflated Tobit model to incorporate excessive zeros. A zero-inflated Tobit model consists of two stages. In the first stage, individuals with 0 income are divided into two groups: genuine zero group and random zero group. Individuals in the genuine zero group did not participate labor market since they have no intention to do so. Individuals in the random zero group participated labor market but their incomes are very low and truncated at 0. In the second stage, the Tobit model is assumed to a subset of data combining random zeros and positive observations. Regression models are employed in both stages to obtain the effect of explanatory variables on the participation of labor market and the income amount. Markov chain Monte Carlo methods are applied for the Bayesian analysis of the data. The proposed zero-inflated Tobit model outperforms the Tobit model in model fit and prediction of zero frequency. The analysis results show strong evidence that the probability of participating in the labor market increases with age, decreases with education, and women tend to have stronger intentions on participating in the labor market than men. There also exists moderate evidence that the probability of participating in the labor market decreases with socio-economic status and reserved wage. However, the amount of monthly wage increases with age and education, and it is larger for married than unmarried and for men than women.

Until recently, self-employment workers are often excluded from labor market studies. Most relevant studies has focused on the determinants of entry into self-employment. However, the self-employment is highly exposed to poverty risk although they are working. Despite that, relatively little is known about the economic severity of the self-employed. This study uses data from the Korea Welfare Panel Study to examine the situation of the self-employed's in-work poverty and the determinants of in-work poverty among them. Major findings are as follows. First, self-employed people experience 3.5 times higher in-work poverty risk than employees. Especially, the ratio of own-account self-employed people living below the poverty line is similar with that of even precarious employees. Second, the extent of poverty of self-employment is more serious. Third, the proportion of self-employed among working poor is about 53% although self-employed workers are composed of only about 24% among working people. Fourth, temporary employees and self-employed people are more likely to be poor than full time employees according to logistic regression. It is statistically significant. It implies that it is desirable to regard the self-employed as the policy target group along with temporary employees. Fifth, the ratio of in-work poverty of self-employed aged 40-64 whose education level is low and the self-employed aged 40-64 who work in low-skilled service sector are higher than that of the other group. It implies that measures to alleviate their economic difficulties are urgently needed.

The study examined the effects of individual, family, and environmental factors on adolescents' self-esteem. Individual factors were the adolescents' health status and their leisure activity experiences, while the family factors were families' socio-economic status(SES) and parenting styles. Three environmental factors focusing on the adolescents' school environment were studied, and they consisted of academic attachment, peer attachment, and teacher attachment. The study inquiries were as follows: which individual factors had an effect on the adolescents' self-esteem? Which family factors had an effect on the adolescents' self-esteem? Which environmental factors had an effect on the adolescents' self-esteem? Of all the factors considered in this study, which factors had the greatest effect on adolescents' self-esteem? This study used data from the 3rd Korean Child and Youth Panel survey of Korean students in the first grade of middle school, and the data were analyzed using multiple regression analysis using SPSS 18.0. The results were as follows: the most important factor that have an effect on adolescents' self-esteem was parenting style, while peer attachment, health status, and academic attachment were also found to significantly affect adolescents' self-esteem. In the conclusion, the researchers suggest various strategies based on results of the analysis to improve adolescents' self-esteem.

In this study, the rate of return on investment used as a proxy variable for the entity's value and financial structure (liability ratio) is related to positive balance. This is consistent with the Static Tradeoff Theory (STT) that the entity's value and financial structure are related to a positive balance because the capital expense of a debt (tax-saving effects) that is less than its equity cost before it is in financial difficulty. Also, operating profitability (EBITDA/Sales), investment safety, total asset growth, net working capital and depreciation expenses are related to negative (-) with financial structure (liability ratio). This is the result of an analysis consistent with the Pecking Order Theory (POT). Fuel costs, borrowing, total asset turnover, financial costs, and tangible asset ratios have a significant positive relationship with the debt ratio. This is consistent with the agency theory and confirms that excessive chartering expenses, such as the bankrupt H company, are the main factors that pressure the financial structure of Korean ocean carriers.

This study conducts differential analysis on the financial positions of Korean shipping companies before and after the bankruptcy of the H carrier, looking specifically at their financial ratios, profit and loss patterns, and other factors related to their financial operation. Firstly, it was discovered that major measures of financial health, such as average assets per carrier, were not affected by the bankruptcy of the H carrier. However, despite this, most carriers experienced large changes in profits and losses, with total sales and shipping revenues averaging 424.5 billion won and 381.7 billion won respectively before the bankruptcy, but falling by half to 252.1 billion won and 234.6 billion won after the bankruptcy. Additionally, charter revenues and expenses also dropped by more than half. EBIT/sales and pre-tax revenue margins were also heavily affected after the bankruptcy, with both figures averaging 8% and 3% respectively before the bankruptcy, but falling into the negative range at -2% and -8% post-bankruptcy, resulting in significant deterioration in operational profitability. The study concludes that there is an urgent need to establish a global sales network, improve cost structures, and consistently secure stable cargo in order to increase Korean carriers' profitability. Of all financial measures, liquidity and total asset efficiency were identified as the most severely-impacted by the H carrier bankruptcy, thereby requiring the most pressing policy addressing.
