This study aims to reveal the influence of price increase in gasoline on household expenditure trade-off. The subjects were 651 households, acquired the first quarter of 1996 and 1997. This study shows the change of the auto fuel budget share in the same household and they were analyzed with the paired t-test, independent t-test. The results are as follows; 1) the price increase of auto gasoline resulted in the increase of its budget share, regardless of a household's true increase or decrease of income. 2) according to price increase in gasoline, the auto fuel budget share has been changed, therefore I divided these changes into three group on the base of it's degree of change. 3) In the group that had a decrease in auto fuel budget share compared to the degree of change, there was a trade-off between the increase in food and light & light water and the decrease of education and auto fuel budget share. Auto fuel in this group was used as discretionary good. 4) In the group that had a similar change in auto fuel budget share compared to the degree of change, there were no trade-off between expenditure items except auto fuel budget share and miscellaneous decrease. This group is the highest income group among the three groups. 5) In the group that had and increase of change in auto fuel budget share compared to the degree of change, there was a trade-off between the increase of eating-out and auto fuel, and the decrease of education and miscellaneous budget share. Auto fuel in this group was used as a discretionary good. 6) trade-off expenditure budget share showed a mixed effect between the influence of increase in gasoline price and influence of increase in true income.

This study is to examine health care utilization and morbidity of disabled and non-disabled children in Korea to evaluate the health disparities. We used medical claim data of 2010 from the National Health Insurance Service-National Sample Cohort data. As a result of the analysis, the disabled children are not in good health condition because they have more frequency of medical service use, hospitalization rate, and more number of diseases and spent more on medical expenses than non-disabled children. Patterns of the most frequent disease differ from significantly between disable and non-disabled. Disabled children had a higher prevalence of selected birth defects and selected health conditions associated with physical disability and a lower prevalence of selected infection disease than children without disability. In conclusion, Health policy changes that would extend the access to health service for children with disabilities characterized by frequent medical care, hospitalization, excessive medical expenditure and complex diseases.

This study was conducted to investigate the effect of moisture absorbent (MA) application timing for litter management on broiler performance, blood cell characteristics, litter moisture content, incidence of footpad dermatitis (FPD), and economics analysis. Treatment include untreated control (NC), 3-week-old litter treatment (PC), 0-week-old (W1), 0 and 3-week-old (W2), 3-week-old (W3) application of moisture absorbent. Six hundred eighty broilers (1-day-old, 42.0±0.24 g) were divided into 5 treatments (4 replications per treatment, 34 birds per replication) and raised for 5 weeks in a floor (2 m² per pen). There was no significant difference among treatments in performance, blood cell characteristics, and H/L ratio according to the application period of litter and moisture absorbent. The litter moisture content and the FPD score were significantly decreased in the litter and moisture absorbent treatments at the age of 5 weeks (P<0.05). The FPD score of broilers was lowest in PC treatment compared to NC treatment (P<0.05). The incidence of FPD was lower in PC and W3 treatments compared to other treatments, and that was the highest in NC treatment. As a result of analyzing the economic feasibility, the highest expenditure occurred in PC treatment, and the lowest expenditure occurred in W3 treatment. Income was the highest in W3 treatment, and lowest in NC treatment. The profit was 185,859 won (1,367 won/unit), the highest in the W3 treatment. In conclusion, when MA was applied to the litter of broiler house at the age of 3 weeks, the litter moisture content and FPD were improved.

The aim of this paper is to address the factors that influence R&D performance of the Korea Institute of Science and Technology (KIST), the representative government-supported research institute in Korea, through an empirical case study. Using the KIST R&D project data from 2004 to 2008, we investigate the determinants of R&D performance through a logistic regression analysis, and compare the results with the survey data we collected from researchers. Our results indicate that total budget, high rate of temporary researchers, and the outcome of the research director's past publications affect publishing performance, while the size of equipment, materials expenditure, and whether the research is outsourced or not affect patent registration performance and technology transfer performance. Contrary to expectations, major factors of publishing performance and that of patent performance are different respectively, and even the results of the survey data we collected from researchers show the difference. Accordingly, the findings of our study suggest the need for research institutes to consider facilitating communication with researchers and enhancing research policy analysis for improving R&D performance.

This paper investigates the relationship between the change of age structure of population and the efficiency of education investment, using cross-section of 106 countries. Based on the existing theoretical arguments, we establish a hypothesis concerning the relationship between age structure and education investment efficiency. The regression results suggest that a country's with a higher ratio of young age to total population results in a lower level of the efficiency of education investment. However, there exists a positive and significant relationship between the ratio of old age to total population and the efficiency of education investment. Therefore, it does suggest that countries experiencing reducing in fertility rate and increasing in expected longevity, such as Korea, not only should be maximized the education efficiency but also contrived for the institutional system for maximization the efficiency of education performance.
