Purpose - This study aims to analyzing of solar power generation cost-benefit. Design/methodology/approach - We analyzed whether there is economic feasibility by selecting parking lots and idle sites located in four areas of Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang areas nationwide, and analyzing site conditions and installation capacity. Findings - According to the results of the analysis, it was found that there is low profitability in Seoul, Gyeonggi and Chungcheong regions, where the solar radiation was not excellent even if REC is selected through the contract market. However, it is necessary to analyzed the economical validity the profitable validity including environmental benefits (greenhouse gas reduction, NOx, SOx reduction effect) and social benefits (renewable power supply) that is analyzed by income and operating costs which is occurred from electricity sales and REC sales when installing solar power generation facilities. Research implications or Originality - In this study, economic feasibility was evaluated additionally in consideration of environmental and social benefits. In conclusion, it was shown that businesses are not economical when considering only simple financial aspects are also sufficiently economical when it is considering environmental and social benefits.

본 연구는 6개월령의 한우 36두를 이용하여 양질 조사료의 보충(Rice straw;RT, Rice straw +cubed roughage;RCT)과 황토의 첨가수준(0%, 1%, 2% 황토)이 생산성, 육질 및 경제적 효과에 미치는 영향을 규명하기 위하여 실시하였다. 실험기간 동안 볏짚에 양질 조사료의 보충(cubed roughage, RCT)은 볏짚단독 처리(RT)에 비하여 일당증체, 사료효율 및 출하체중에서 각각 10%, 6.8%, 8.2%로서 유의적으로 증가되었으나(P$<$0.05), 황토의 첨가는 한우의 성장성적에 뚜렷한 효과는 없는 것으로 나타났고, 2%의 첨가수준은 오히려 감소되는 경향을 보였다. 육질 및 경제성 분석에서는 RCT구는 뚜렷한 개선효과를 보였지만, RT구에서는 황토 1%에서만 첨가 효과가 있는 것으로 나타났다. RCT구에서는 1%, 2% 모두가 0%에 비하여 보다 개선된 결과를 나타내었다. 이와 같은 결과들은 한우 비육에 있어서 황토의 첨가는 성장성적에는 뚜렷한 효과가 나타나지 않았지만 육질과 경제적 효과에서는 1%의 첨가는 개선효과가 있는 것으로 사료되며, 고급육 생산을 위한 황토의 첨가시에는 양질의 조사료 보충이 경제적 효과성을 더욱 향상시킬 것으로 사료된다.

Many services have been served by the exiting subway systems since they have opened in 1975. But its efficiency and competition were going down because of the high construction cost and difficult connection with other transportations, etc. Otherwise, the light rail transit system is much lower construction cost than the subway and the high way building. Also those systems are good at the inexpensive operation cost, the fixed time and safety, the easy access. Recently, the several provinces are planning or advancing the light rail transit system because of these many benefits. Consequently, those system's economical feasibility analysis is required rapidly to show the resonable construction's cause and to get the private investment. This paper offers the system's economical feasibility through the several benefit analysis after the light rail transit system's construction.

Purpose: In this study the costs and benefits of a home health care program were examined to evaluate the economic feasibility of the program. Methods: The study participants included 349 patients in the community who had been registered at a home health care center for 5 years. The costs and benefits of the program were analyzed using performance data and health data. The benefits were classified as the effects of pressure ulcer care, skin wound care and catheters management. The program effect was evaluated on the change of progress using transition probability. Benefits were divided into direct benefit such as the savings in medical costs and transportation costs, and indirect benefits which included saving in productivity loss and lost future income. Results: Participants had an average of 1.82 health problems. The input cost was KRW 36.8~153.3 million, the benefit was KRW 95.4~279.7 million. Direct benefits accounted for 53.4%~81.2%, and was higher than indirect benefits. The net benefit was greater than 0 from 2006 to 2009, and then dropped below 0 in 2010. Conclusion: The average net benefit during 5 years was over 0 and the benefit cost ratoi was over 1.00, indicating that the home health care program si economical.

Power bloggers have become one of the most important resources of blog service companies, and only those who attract and secure power bloggers will be able to have competitive edge and profitability in blog related businesses. This study examines the effects of technology acceptance factors and economical factors on the loyalty of power bloggers. The analysis results show that the usefulness, power of social influence and enjoyment positively affect the attitude and intention to continuous use. The relationship between the attitude and intention to continuous use is demonstrated as significant. The economical benefit exhibits weakly positive influence on the attitude to blogging, but not on the intention. This indicates that although many power bloggers receive economic benefits through their blogging activities, such economical benefits do not have big impact on their activities and the intention to use. The blog service providers may use the analysis results when developing new blog services. In particular, the usefulness, which is often considered as one of the most important factors in the success of the blogosphere, is found to have less impact than the enjoyment among power bioggers. This is because blog users, especially power bloggers, use the blog not for a specific purpose or for generating a special product; most of them use the blog to satisfy their own personal desires. When developing blog services, therefore, it is important to cater to the users' enjoyment and their psychological compensation. What is surprising is that the effect of the economical factor is not ad significant as one might have expected. This implies that the new blog services that provide profit sharing or advertising revenue sharing may not be as successful as one would have hoped for in maintaining the loyalty of power bloggers.

In light of the growing traffic congestion problem and congestion cost, the container transport by railway has to be increased. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the DMT(Dual Mode Trailer) transport system which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. The DMT transport will therefore serve the areas required by transport organizers. The purpose of this paper is to estimate economical feasibility analysis for development of DMT transport system. Consequently, this study analyzed the characteristics of the DMT system. The horizontal load.unload system is being considered as an adoptable DMT system in consideration of the situation in Korea.

The survey was conducted from June $1^{st}$ to $20^{th}$ in 2009, and 303 responses were used in the data analysis. A frequency analysis, factor analysis, reliability analysis, and multiple regression analysis were conducted for the statistical analysis. The results show that the eco-friendly attitude is classified by environmental concern, awareness of environmental consumption, and participation in the environmental movement. The benefits pursued in clothing are classified by fashion pursuit, brand pursuit, functional pursuit, personality pursuit, and economical pursuit. The awareness of the environmental consumption factor in the eco-friendly attitude influences the purchase satisfaction of eco-friendly consumers for infants and children's underwear. The fashion, brand, functional, and personality benefits pursued in clothing effect the purchase satisfaction of eco-friendly consumers for infants and children's underwear.
