This study is intended to suggest a more reasonable and practical method of estimating discount & capitalization rate for valuation of closely-held culture content business, that is, to modify the Buildup Summation Model(which is recommended for the closely-held business by the NACVA) by adopting the weighted ratings in the CT Project Investment Evaluation of the Korea Culture Contents Association to risk factors of the Buildup Summation Model. This method is ease to apply for closely-held culture content business and has advantages in applying the weighted rates based on the characteristics of respective culture contents. And it can make up for the Weighted Average Cost of Capital (WACC) which shows generally low discount rates.

Recently, with achieved US$ 500 Billion international cumulative construction order, the Korean government presented overseas construction industry visions for international orders of US$ 100 Billion and entering the top five countries in global construction market. Also, Korean companies are developing strategies for expansion of international markets. However, ODA loan projects are low risk for the Korea Construction companies trying to advance their overseas business. This study provides data-based advice on securing competence for Korean construction companies entering the global market through the ODA loan projects. To analysis construction firm's competitiveness for ODA loan project, FGD was utilized and BSA model was applied to the valuable analysis. Competencies highly assessed were construction quality control, relationship building through high-level diplomatic activities, and project management. Competencies requiring urgent improvement were handling risks of local countries, financing projects, and developing know-how within participating companies.

Koran Government introduced BTL(Build-Transfer-Lease) to provide convenience through early supplying infrastructure and plans to invest 8,315million dollar to 84 projects of 15 BTL type involving official residence and railroad. But some of construction company hates to invest BTL projects because of its low earning rate. In addition if we correctively apply project which partly has profitability to BTL, the earnning rate declines more seriously. So this paper presents BTL+BTO model which operates BTL in the non-profitable parts to improve convenience of users and BTO in the profitable parts to improve earning rate. BTL+BTO model based on operate period was presented and its suitability was confirmed by applting 00 region official residence project.

Managing investments in renewable energy (RE) in developing countries is essential for reducing environmental pollution, meeting the growing energy demand, and avoiding the risk of stranded assets. Establishing Public-Private Partnerships (PPPs) is necessary to address budgetary and technical issues in developing countries. PPPs recover investments through long-term operations. Risks from external political, social, and economic environments during both the construction and operational phases of PPP projects affect the stability of investment recovery. Although various support systems are in place to mitigate investment risks for investors, these systems can pose risks to the public sector. Therefore, this study identifies common risks, including construction and operational risks, as well as political, financial, and social risks, for sustainable renewable energy PPP operations. Interpretive Structural Modeling (ISM) and MICMAC (Matrix Impact Cross-Reference Multiplication Applied to a Classification) analyses were conducted to understand the interrelationships among these risks. The ISM and MICMAC analysis results showed that construction phase risks have high dependence power and driving power. In contrast, operational phase risks exhibit low driving power but high dependence power. This indicates that managing construction phase risks is effective for the sustainable operation of renewable energy PPPs. Based on the analyzed ISM and MICMAC results, preventive measures for sustainable operations of renewable energy PPPs were proposed.

Korean construction companies first advanced to the international markets in 1960's and so far have brought more than 4,900 projects which account for 193 billion dollars approximately. With the large increase of national employment and income being followed by the achievement, Korea's construction industry has made an enormous contribution to the improvement of domestic economy for the last 40 years. However, recently the increased risk in international markets as well as the sharpening competition with foreign companies promising in terms of advanced technologies and low labor cost have been driving Korean construction away from the market shares. According to ENR (Engineering News Record, 1994~2003), it is revealed that 15.1% of top 225 global contractors are suffering from loss in international construction markets. This phenomenon is largely due to the highly uncertain characteristics of international projects, which are inherently exposed to various and complicated risky situations. Furthermore, especially for Korean construction companies, it is often the case that the failure in an international construction project cannot be offset by even a sufficient number of successful domestic achievements. Therefore, not only the selective screening among the nominated projects which have strong possibility of collapse but the systematic strategies for controlling potential risk factors are also considered indispensable in international construction portfolio management. The purpose of this study is to first analyze the causal relationships of the profit-influencing variables and the project success, and develop the profitability forecasting model in international construction projects.

Objective: The objective of this study is to examine the association between process quality of inpatient care and risk-adjusted, thirty-day potentially preventable hospital readmission (PPR) rates. Data Sources/Study Setting: This was an observational cross-sectional study of nonfederal acute-care hospitals located in two states California and Florida, discharging Medicare patients with a principal discharge diagnosis of heart failure, acute myocardial infarction, or pneumonia January through December 31, 2007. Data were obtained from the Healthcare Cost and Utilization Project State Inpatient Database of the Agency for Healthcare Research and Quality, Centers for Medicare and Medicaid Services Hospital Compare database, and the American Hospital Association Annual Survey of Hospitals. Study Design: The dependent variable of this study is condition-specific, risk-adjusted, thirty-day potentially preventable hospital readmission (PPR). 3M's PPR software was utilized to determine whether a readmission was potentially preventable. The independent variable of this study is hospital performance for process quality of inpatient care, measured by hospital adherence to recommended processes of care. We used multivariate hierarchical logistic models, clustered by hospitals, to examine the relationship between condition-specific, risk-adjusted, thirty-day PPR rates and process quality of inpatient care, after taking clinical and socio-demographic characteristics of patients and structural and operational characteristics of hospitals into account. Findings: Better performance on the process quality metrics was associated with better patient outcome (i.e., low thirty-day PPR rates) in pneumonia, but not generally in two cardiovascular conditions (i.e., heart failure and acute myocardial infarction). Practical Implication: Adherence to the process quality metrics currently in use by CMS is associated with risk-adjusted, thirty-day PPR rates for patients with pneumonia, but not with cardiovascular conditions. More evidence-based process quality metrics closely linked to 30-day PPR rates, particularly for cardiovascular conditions, need to be developed to serve as a guideline to reduce potentially preventable readmissions.

Objective: This study was conducted to evaluate an education program for cardiocerebrovascular high-risk patients. Methods: This program was developed according to Tyler's model for curriculum development. To evaluate the effects of this program, we measured clinical outcome change (weight, waist circumference, systolic blood pressure, diastolic blood pressure) and behavior change stages (checking blood pressure, blood sugar levels, doing physical activity, consistent maintenance of food intake, eating low amounts of salt, abstention from tobacco and alcohol) before and 4 weeks after participation in the education program. The group of subjects consisted of High-risk group patients who attended basic program(32 patients), and staged program(37 patients) during KHyDDI meetings from Oct. 2009 to May 2010. Results: The staged educational program was developed three aspects(disease, nutrition and exercise)and three stages(basic, in-depth and individual education). In the staged education program, the evaluations were made by measuring clinical outcome and stage of behavior before and after education. Significant differences were found in waist circumference, systolic blood pressure, diastolic blood pressure, consistent maintenance of food intake(p<0.05), and eating low salt(p<0.001)and their self efficacy. Conclusion: In the practice-oriented staged education program, significant differences were found in the clinical outcomes and stage of behavior before and after education. Possible limitations of the study include the small number of participating subjects and the short follow-up management period, but the results indicate that continued application of this program could contribute to the prevention of cardiocerebrovascular diseases for the elderly patients with long periods of chronic diseases.

The Agricultural Land Remodeling Project was launched for agricultural fields with potential risk of flooding which were placed in low-lying area as a part of agricultural sectors of the National 4 River Project. It induced of the reclaimed agricultural fields on a national scale. The arable lands reestablished by reclamation have caused several big problems such as destruction of soil physicochemical properties, and thus the techniques to solve disadvantages were urgently required. In this study, we collected experimental samples from top soils in three agricultural areas, one from conventional agricultural fields (Hwasun, Jeollanam-do) and the others from reclaimed (remodelled) agricultural fields (Naju, Jeollanam-do and Gumi, Gyeongsangbuk-do), The soil chemistry data were analyzed using statistic tools such as semi-variance and kriging, and differences between natural and reconstructed soils were examined. The score, R (Ao) which indicates a dependence distance between each chemical element, was as follows; 21.8~43.5 (Conventional, Hwasoon), 4.4~70.6 (Remodelled, Naju) and 5.3~43.6 (Remodelled, Gumi). These results suggested that chemical properties of the reclaimed agricultural fields had a huge variation. Moreover, the result of kiriging maps also represented a ununiform pattern in the reclaimed lands. As a result of this study, it is strongly required to build up the soil type-specific management techniques for the reclaimed agricultural lands.
