The economic feasibility analysis including benefit-cost ratio and internal rate of return of a land consolidation and on-farm development project was mainly depended upon the direct benefits and costs arising during project life. Therefore the projects were neglected in allocating the government's financial funds and loans on account of the low economic rate of return of the project. Accordingly the extended benefit-cost analysis method should be introduced and adapted to cover not only the benefit s such as non-market values of environmental and food security fun ct ions of the project but also market values of the project outputs. The main purposes of this study are (1) to prepare a guide line for economic feasibility analysis based on the IBRD and ADB guidelines, (2) to estimate the benefits from productivity increase, labor saving, savings of O&M cost of farm mechanization and project facilities, savings of farmer's burden for their public health, increasing environmental and public functional value of paddy fields, improving food security condition and formation of peaceful and uncontroversial rural society by implementing the land consolidation and on-farm development, (3) to introduce the newly adapted analytical method as the extended benefit cost analysis which could make possible to be included the values of non-market goods such as the food security and the environmental public function of paddy fields. To carry out this study, the existing publications on the guidelines for economic agricultural projects were reviewed and consultation was made with a For the post evaluation study of the land consolidation and on-farm development project, field survey in Jigok and other comparative area were made to get available information. According to the project completion report, Jigok land consolidation and on-farm development project has 55ha of benefit area out of 69ha of gross area. The project was started in November 11th, 2000 and completed october 30th, 2001. The total project costs were amounted to 2,548 million won and the annual project benefits were estimated at 335million won evaluated by domestic market prices. The ERR(Economic Rate of Return) and SRR(Social Rate of Return) of the project based on the shadow pricing system were estimated at 4.4% and 16% respectively. On the other hand, the ERR and SRR based on the domestic market value system were amounted to 6.37% and 14.62%. In conclusion, Korean land consolidation and on-farm development projects have not carried out from the view point of economic rate of return under shadow pricing system but from the view point of domestic pricing system. For the future feasibility studies on land consolidation projects have to be carried out including the non-market values as environmental and food security function of the projects.

This study attempts to examine standards on the effectiveness of the rights to social security of people with disability. The current research makes the standards on effectiveness of social security rights to the disabled. This standards draw four right areas and five general principles from debates about effectiveness of general social security rights and extend for applying three social area to the disabled. Four right areas are benefit coverage, benefit structure, benefit restriction and rights relief. Five general principles are enforceable rule principle, national finance principle, unconditional principle, adequacy principle and penalties principle. These four right areas and five general principles apply to three social security areas of income support, employment security and medical security. Measurement values are 'high' and 'low'. These measurement values divided into two that are used to ensure same intervals. This study on standards to the effectiveness of the rights to social security of people with disability has political and theoretical implications. First, in political aspects, these standards provide objective understanding of the present level of social security policies for the disabled. Second, theoretically the current study expands debates about the effectiveness of general social security through multi-disciplined research. At once this study is significant to establish empirical research foundation.

Objectives: The low benefit coverage rate of South Korea's health security system has been continually pointed out. A low benefit coverage rate inevitably causes catastrophic health expenditure, which can be the cause of the transition to poverty and the persistence of poverty. This study was conducted to ascertain the effect of catastrophic health expenditure on the transition to poverty and the persistence of poverty in South Korea. Methods: To determine the degree of social mobility, this study was conducted among the 6311 households that participated in the South Korea Welfare Panel Study in both 2006 and 2008. The effect of catastrophic health expenditure on the transition to poverty and the persistence of poverty in South Korea was assessed via multiple logistic regression analysis. Results: The poverty rate in South Korea was 21.6% in 2006 and 20.0% in 2008. 25.1 - 7.3% of the households are facing catastrophic health expenditure. Catastrophic health expenditure was found to affect the transition to poverty even after adjusting for the characteristics of the household and the head of the household, at the threshold of 28% or above. Conclusions: 25.1% of the households in this study were found to be currently facing catastrophic health expenditure, and it was determined that catastrophic health expenditure is a cause of transition to poverty. This result shows that South Korea's health security system is not an effective social safety net. As such, to prevent catastrophic health expenditure and transition to poverty, the benefit coverage of South Korea's health security system needs to the strengthened.

The degree of income inequality deepened by health care expenditure was useful in assessing the health security level. This exploratory study was conducted to provide a basic evidence to prove the necessity of reinforcement the benefit coverage of South Korea's health security systems. Data from the Household Income and Expenditure Survey of Korea and Luxembourg Income Study were used. Income inequality indices before and after deduction of health care expenditure were computed, and the degree of the increase in the indices was compared among 13 countries. The degree of decrease against the effect of income inequality reduction policies by health care expenditure was determined. The relationships between the national characteristics and the increase in income inequality were examined. In South Korea, all income inequality indices increased after deducting health care expenditure, but the difference was not high compared to the mean of 13 countries. However, the degree of decrease against the effect of income inequality reduction policies by health care expenditure was high, compared to the mean of 13 countries. The proportion of public sector spending on health care proved to be statistically significant with the increase of income inequality indices (p<0.05). In the context of the continuous increase in health care expenditure, if benefit coverage of health security systems is not reinforced, income inequality will all the more increase due to health care expenditure. In the establishment of the policies for reinforcement of the benefit coverage, income inequality after deduction of health care expenditure should be continuously monitored.

The Ministry of Health and Welfare of Korea has implemented various social security programs to ensure a basic standard of living and raise overall quality of life for all citizens. The Korean social security system provides social insurance, public assistance, and social welfare services. To achieve adequate drug benefits, the Drug Management Department of Health Insurance Review and Assessment Service (HIRA) implement drug management duties including drug listing, upper price limit setting, scope of benefits, and post-factum management. When a manufacturer or an importer wants to apply for National Health Insurance (NHI) coverage of the drug that has obtained safety and efficacy approval, the pharmaceutical benefit assessment committee of HIRA evaluates the drug's clinical efficacy and cost-effectiveness to determine whether or not to include the drug into the benefit package. The benefit standards for a listed drug (ingredient) are set either for the whole permitted range or a part of range with conditions. To increase the coverage rate for new drugs, the listed drugs are regularly reviewed for their value. The status of listed drugs can be adjusted or eliminated from the benefit package if the clinical efficacy turns out to be insignificant. Therefore, through these pharmaceutical management procedures, high-quality drugs are provided at reasonable prices, which save healthcare expenditure by price determination and selective coverage in consideration of economic evaluation.

The World Customs Organization (WCO) has designed standards to secure and to facilitate the ever-growing flow of goods in international commerce since 9.11 terrorism in U.S.A. These standards are set forth in the SAFE Framework of Standards, which was adopted by the WCO Council at its 2005 Sessions and the SAFE Framework incorporates the concept of the Authorized Economic Operator (AEO), and the Council directed the WCO to develop more detailed implementing provisions for the AEO concept. It is considered to be reliable in customs-related operations and ensures an equivalent level of protection in customs controls for goods brought into or out of the customs territory, whereas it is difficult for many Korean companies to make a decision of introducing the AEO certification programs because of a lack of cost and benefit information. In this article, We have reviewed the definition and the developing status of an AEO programmes and have studied the benefit and expected effect through documentary research methods. Therefore, it is essential for Korean companies to be certified the AEO programmes from Korea customs service for increasing security in international supply chains through risk management and customs compliance, in addition, the key-driver in the future will be expectations from the business community to work with AEO partners.

The smart cities are evolving constantly and are responsible for the current transformation of cities and countries into a completely connected network of information and technology This interconnected network of a huge number of smart devices is capable of exchanging complex information and provides tremendous support including enhanced quality of life within urban locations. Unfortunately this set-up is vulnerable to security attacks and requires the widespread ubiquitous network to authorize access through privacy and thus offer security in order to ensure civilian participation in a country. The smart network should benefit the individuals of the country by developing potential strategies to protect the smart cities and their participating entities from the unauthorized attacks. Trustworthy data sharing strategies based on the utilization of advanced technology features via smart communication network could solve some issues of privacy and security. This paper presents the challenges and issues related to protection and highlights the important aspects of securing the smart cities and its components. It also presents the role of cloud security for building a secure smart city.

This paper presents a theory on the pricing and allocation of spinning reserve. It is shown in this paper, that it is possible to maintain system security with many participants each attempting to optimize their own benefit, through pricing incentive. Participant offers power consumption/generation and reserve contribution according to its price. And Price setter only distribute pricing signal to acquire system security. Participants induce disturbance on power system and they pay the penalty according to the size of disturbance. And they also offers some reserve capacity to earn reserve cost. In this scheme, the amount of data communication is very small.
