This study provides a thorough methodology for IT Investment evaluation. A software tool to support the evaluation process was introduced along with a case study. The software supports the methodology that consists of 7 phases : Target analysis, ldentifying IT measures, Measuring IT impact, Assessing business value, Analyzing the decree of realization, Cost-benefit analysis, and Reporting. The case study showed that the software (CAFA) was a very useful tool supporting both decision-making and post-implementation reviews of IT investment.

This paper presents an approach to B/C analysis amenable to evaluate the impact of DSM programs especially on the strategic conservation programs and the load management programs. The proposed approach embedding the existing B/C analyses is applicable to the new electricity market Case studies show the B/C ratio and the avoided cost due to the impact of DSM programs.

Domestic versus overseas postgraduate education in science and engineering has its own advantages and disadvantages. One of the issues involved in developing countries is the problem of brain drain. This study deals with the cost and benefit of domestic and foreign education, problems in brain drain and the social and private rate of return analysis in postgraduate science and technology education in Korea.

This paper proposes the cost analysis on the energy efficient equipment when this equipment is participated in the demand-side bidding. Conventional demand-side bidding is exercised through load re-distribution. However if this load reduction is exercised by the use of high efficient equipment, its effect will be assumed to be more economical. This paper analyses this cost-benefit effect of high efficient equipment in the demand-side bidding.

This study seeks to determine causal relationships between hotel internal marketing practices and job satisfaction, and ultimately on organizational commitment, to contribute information enabling hotel management to better understand employees working in hotel culinary departments. SPSS 18.0 and AMOS 18.0 were employed for the statistical analysis (e.g. frequency statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis, and structure equation model). Results revealed that the formulated model showed proper model fit (${\chi}^2=227.154$(df=179), p-value=0.009, CMIN/DF=1.269, RMR=0.013, GFI=0.931, AGFI=0.911, NFI=0.906, CFI=0.978, RMSEA=0.031), and confirmed construct reliability and convergent validity. Three factors (benefit package, educational training, work autonomy) were extracted based on the results of the factor analyses. Specifically, benefit package and work autonomy exhibited an effect on job satisfaction with benefit package asthe most significant factor (t-value 3.311, p<0.001), partially supporting the first hypothesis of this study. In addition, job satisfaction has found to have a positive influence in organizational commitment, confirming the second hypothesis of this study.

For economic impact analysis on a R&D project of high-yield groundwater development in Jeju conducted by KIGAM from 2004 to 2007, benefit/cost ratio(BCR), net present value(NPV), and internal rate of return(IRR) were calculated by contingent valuation method(CVM), production function analysis, domestic water market analysis and technology factor analysis. Measurable direct impact parameters among the major outputs of this R&D project consisted the estimation 4 high-yield and high mineral groundwater reserve in Jeju. Annual use of the reserve by piped water and bottled water was estimated as 12.23 million ton and its monetary value was calculated as 293.4 million dollar in 2006 year value applied of 5.5% discount rate. Economic impact of this R&D project in NPV of year 2006, with applying a discount rate of 5.5%, was identified and estimated as 13.66 million dollar in NPV, 4.05 points in BCR, and 22.74% in IRR, respectively. Additional early launch benefit was 5.58 million dollar. Even increased of the 1% discount rate, NPV of this R&D project was also positive as 12.18 million dollar and BCR was 3.71.

The purpose of this study was to examine the economic feasibility of providing services according to the nationwide expansion of early warning services. The net present value method, one of the cost-benefit analysis methods, was applied to the analysis. As a benefit item that constituted the net present value, the damage reduction amount using crop insurance data and the willingness to pay for the use of early warning services were used. The cost items included system construction and maintenance costs, and text transmission costs. As a result of the analysis, it was found that the nationwide expansion of early warning services had economic feasibility, and its economic effect varied depending on the level of text message use (10 % to 40 %, 10 %p interval) of participating farmers. In the future, the economic effect of early warning services is expected to increase further due to the increase in the number of farmers participating in early warning services and the increase in crop damage caused by climate change. It is necessary to further enhance the economic effect of early warning services by actively utilizing information delivery means through apps or the web as well as text messages.

In 2012, Psy's music video 'Gangnam Style' spread through parodies, and gained explosive popularity. In 2016, there was a case so-called as 'baseball ground cheering song' in which a author(songwriters) claimed an infringement of the 'right of integrity' related to cheering songs used by professional baseball teams. In response, the court denied violating the right of integrity in 2019. These cases have different effects depending on whether or not the 'right of integrity' is claimed. This study attempted an economic analysis in addition to a legal analysis of the right of integrity. Korean copyright law regards even simple changes that go against the author's will as a infringement of the 'right of integrity' even if they do not harm honor or reputation. Such legislation is one of the most strongly protected forms in the world, so it cause many problems. Meanwhile, we analyzed the cost-benefit analysis of Psy's 'Gangnam Style' case and the 'baseball ground cheering song' case. As a result of the analysis, the right to integrity is inefficient in quantitative and qualitative aspects. Therefore, the right of integrity should be reconsidered with the focus on 'popular music'. In particular, considering the development of information communication technology and changes, a revision direction is needed to meet the purpose of the copyright act. Furthermore, in order to solve the legal issues under the Copyright Act, the requirement for infringement of the right of integrity should be relaxed. Then, we proposed the establishment of a proviso clause on the right of integrity.
