This study examined how much support families with pre-school children receive for child care along with the types of support they receive. The paper also investigated the factors that influence the financial and social support received from government, employers and grandparents of the children. Data for this study were obtained from a questionnaire completed by mothers of pre-school children (n=641) during the spring of 2009. The data were analyzed by the following methods: $\chi^2$, t-test, ANOVA, Logit analysis, and Tobit analysis using SPSS and STATA software. The profile of support for child care showed that approximately 33 percent of families with pre-school children received free or subsidized child care from the government, 12 percent received some forms of support for child care from the parents' employers, and 26 percent received support from grandparents either financially or in the form of free child care. The results of the Logit analysis demonstrated that families with pre-school children were more likely to receive child care subsides from the government when they had a higher number of pre-school children and a lower level of family income. The significant factors that influence support from employers were mother's educational level, the number of pre-school children, and family income. The significant factors that affect support from grandparents of the children were the mother's age, the mother's employment status, the type of residence, and the family type.

Although renewable energy sources are more environmentally friendly than fossil energy sources, they are far more costly and hard to survive in the electricity market. For a competitive renewable electricity, the government should take 'visible' actions to compensate higher production costs. Popular policies, such as Feed-In-Tariff and Renewable Portfolio Standards, are financed by an undifferentiated increase of electricity bills (a collective financing mechanism) but are occasionally confronted with the opposition of the electricity consumers. This paper discusses the consumers' willingness to pay for renewable energy in order to back up the voluntary financing mechanism, the Green Pricing. The Tobit analysis of a consumer survey shows that the consumer's WTP is positively influenced by his environmentally friendly activities under both financing mechanisms. The knowledge on renewable energy is statistically significant only under collective financing mechanism.

Using the data of 'middle-and old-aged people' in the 6th year(2003) of KLIPS(Korea Labor and Income Panel Study), this study compared entirely retired men's income source and amount of income divided by the time of retirement and analyzed the determinants of main income source and amount of income level using Multinomial Logit Analysis and Tobit Analysis. The results of these were as following; First, Entirely retired men has average 1.27 income source and the amount of income from main income source is positioned at 85% of total income. This result indicates the lack of variety to get opportunities of income sources for the living and also means high risk associated with the entirely retired men if he looses the main income source. Second, most of income source of entirely retired men is spouse's earned income or private income transfers, however, if we divide those as timing of retirement and characters of each individual, it is represented that the most of income source is differentiated by the position at labor market during work life and the opportunity for building the wealth, and the possibility of obtaining public pension and public support. Third, the income level depends on what sort of income source the retired men has, this shows that there is not a strong relationship between obtaining a Income source and gaining above the certain level of income.

The purpose of this paper is to estimate technical efficiency, scale efficiency, and environmental efficiency by income level of Korean farms, and analyze the factors to decide three efficiencies. Depending on the non-parametric methods, we estimate technical using inputs and outputs of total farms without assuming of goods or behavior of optimization. The average technical efficiency of total firms under constant return to scale and strong disposability is 0.437. The technical inefficiency was caused by 47.7% in pure technical inefficiency, 11.3% in scale failure, and 3.2% in environmental inefficiency. The number of firms under increasing return to scale occupied almost 70% and 27% of total firms respectively. Higher are income class, middle debt & long debt per asset, and N effluents per cultural land, higher technical efficiency. The increases of BOD discharges per cultural land and machines per cultural land deteriorate environmental efficiency.

The purposes of this study were to explore amount of time use for house work, leisure and extracurricular lesson used by adolescents and to explain its influencing factors. Tobit model was used to analyze the factors of time use because amount of time use was a limited continuous variable. The results of this study were as follows: 1) Amount of time used for house work per day by adolescents was found to be 36min. for weekdays and 64 min. for holidays. Amount of time used for passive leisure per day by adolescents was found to be 203min. for weekdays and 375 min. for holidays. Amount of time used for active leisure per day by adolescents was found to be 74 min. for weekdays and 194 min. for holidays. Amount of time used for extracurricular lesson per day by adolescents was found to be 96min. for weekdays and 36 min. for holidays. 2) Time use for house work was found to be significantly influenced by education status, education level of mother, job status of mother for weekdays and gender, education level of mother, job status of mother, household income for holidays. Time use for passive leisure was found to be significantly influenced by education status, small children at home for weekdays and gender, education status for holidays. Time use for active leisure was found to be significantly influenced by gender, education status for holidays, while there was no influencing factors for weekdays. Finally, time use for extracurricular lesson was found to be significantly influenced by gender, education status, household income for weekdays, and age, education level of mother for holidays.

Countries around the world are propelling policies and strategies to strengthen the competitiveness of their own ports as they recognize the roles and importance of the ports in the international trade and logistics. The main objective of this study is to compare efficiencies of major container ports and analyze the factors that affect the efficiencies in the three regions of East Asia, Europe, and North America, which cover most of world container shipping. We employ DEA models in analyzing the efficiencies of 45 container ports using 5 input and 2 output variables. We also carry out regression analyses to estimate the impacts of each factor on the throughput (TEU), overall technical efficiency (OTE), pure technical efficiency (PTE), and scale efficiency (SE). The analysis results show that East Asian ports, despite being smaller in average size, make greater output and achieve higher technical and scale efficiencies than European or North American ports.

Korea Highway Corporation has played a role of the construction and operation of the highway for the past for 40 years. The private sector since the 90s has made highway construction and operation. Central government and local governments were paid at subsidy in least operating income to 1.5896 trillion won for private operators from 2001 to 2008. Thus, Korea Highway Corporation will have important implications for understanding the cost structure. Korea Highway Corporation, a general analysis of the input element is used efficiently. And the operation of labor and capital estimated highly of the substitution elasticities. Korea Highway Corporation are judged to need financial separation of a strategic outsourcing(business) enabled and the construction(maintenance and management) and business institutions. In addition, currently running at highway the operation of institutions combined to configure a new institution, if that institution invigorate the hi-pass, more of the country's highway believe to be increase operational efficiency.

In this paper, we investigate the relationship between IPR creation and export activity. And we try to examine the effects of IPR use as innovation on export performance. The dataset used in the empirical analysis are the annual "Survey of Business Activity(2006~2014)" panel data which include total of 6,144 samples of firms. Data set includes the sample characteristic such as employee, industry, export performance, possession/use/development of IPR. According to analysis results, this paper confirms that R&D and export activities of firms make positive effects on IPR creation. In addition, this paper finds that IPR use of firms make positive effects on firm's export performance. Exporting firms achieve higher export performance by developing new products and processes to enter and compete in overseas markets. In addition, exporting firms can achieve higher performance by using intellectual property rights to appropriate innovation outcomes in foreign markets and to exclude the possibility of patent disputes in advance.

This article aims to investigate the impact of Korean employment protection legislation that has implemented since 2007 on eliminating discrimination on non-regular worker's wage and social security. It is used the panel Tobit model reflecting the variation of implementation time according to the size of establishments. Although the employment protection laws for non-regular workers have implemented, the wage gap and discrimination in social security for non-regular workers have continued. Of course, the discrepancies on wage and social security were founded not only between regular and non-regular workers but also within non-regular workers. For reducing the discriminations, this study proposes to restrict the reason for justifying discrimination, and the introduction of a new approach to accessing the discrimination and complimentary credit system. Besides, this study suggests to actively review the strengthening of regulations on the use of non-regular workers.
