Present private infrastructure investment in SOC investment has increased up to $11\%$ compared to the year 2003 and it is expected to increase in the future. In spite of its rapid increasement we don't have definite standard or system on distinctly presented rate of return for domestic private infrastructure investment yet, and practical and scientific research is not sufficient, compared to its necessity and importance. Hence, in this study we tried to build theories systematically, which are related to rate of return of private infrastructure investment to promote SOC private infrastructure investment to last successfully and present the proper level of rate of return of private infrastructure we investment appropriate in domestic situations through diverse analysis. Therefore, to present reasonable rate of return, we used 5 methods: existing research analysis, case study, financial index analysis, analysis of investors rate of return, and analysis of rate of return in a real estate market. After comparing and analyzing these methods, Ive presented in the end the appropriate level of rate of return of private infrastructure investment, which can be applied in a domestic market.

The purpose of this study was to identify the characteristics of consumers who purchase home meal replacements (HMR) and to analyze the differences for frequency of use, preference, satisfaction, and repurchase intention based on HMR product categories. The subjects were adults in their twenties or older, who had used HMRs and lived in Seoul and the Gyeonggi Province of Korea. Five-hundred and fifty subjects were chosen by random sampling, and questionnaires were distributed from March 12 to 30, 2005. A total of 451 questionnaires were returned (the rate of return was 82%). The primary results of the study are as follows. First, by analyzing for differences based on the demographical characteristics of the HMR consumers, men had higher 'frequencies of use' and preference, whereas women had higher satisfaction and 'intentions to purchase again.' This implies that HMRs assist women who are usually in charge of home food preparation, based on time and cooking effort; hence a higher satisfaction among the women. Second, by analyzing for differences based on the characteristics of HMR consumers who ate the products, 'frequency of use' (p<.001), preference (p<.01), satisfaction (p<.001), and 'intention to repurchase' (p<.001) for the 'ready to eat' HMR category, by the person who prepared the food, were significantly higher for those subjects in their 20s than for those in other age groups. As for persons influenced by the meal, the teen age group had significantly lower 'frequency of use'(p<.001), preference (p<.05), satisfaction (p<.01) and 'intention to repurchase' (p<.01) than other age groups. 'Frequency of use' (p<.001) and preference (p<.05) were lower if the person influenced by the meal was one's spouse or child than if the person influenced by the meal was oneself. Third, regarding the preference for eating at home or eating out, 'frequency of use' was significantly higher than the other analyzed factors for the 'ready to eat,' 'ready to heat,' and 'ready to end-cook' HMR categories. In short, the 'frequency of use' for HMRs was higher for those who preferred to eat at home versus eating out, simply as a result of being bored with eating out, which is essentially the reason for the origin of HMR.
