In this paper, we report the public IT policy case results to restructure informatization level indices for small and medium sized enterprise(SME). The indices restructuring project was initiated by TIPA with the group of experts during 2011, and the newly amended indices was employed as the formal instrument to measure SME informatization level. The critical drivers to reform the indices include simplification for more accurate measurement of SME informatization level, reshaping key representative indices of smart IT to better publicize SME's interest toward advanced IT, and systematic reconfiguration of performance measures which reflect business performance enhancement effect through IT investment. Indeed, the IT performance indices are unified to incorporate the instrument for general SME informatization level survey and IT adoption subsidy's effectiveness appraisal. The procedures and details of logic illustrated in this paper provides useful insight for successful implementation of SME informatization as well as for the better policy deployment of IT subsidization for SMEs.

Recently, various energy efficiency optimization activities are ongoing globally by integrating conventional grids with ICT (Information and Communication Technology). In this sense, various smart grid projects, which power suppliers and consumers exchange useful informations bilaterally in real time, have been being carried out. The electric vehicle diffusion program is one of the projects and it has been spotlighted because it could resolve green gas problem, fuel economy and tightening environmental regulations. In this paper, the economics of V2G system which consists of electric vehicles and the charging infrastructure is evaluated comparing electric vehicles for V2G with common electric vehicles. Additional benefits of V2G are analyzed in the viewpoint of load leveling, frequency regulation and operation reserve. To find this benefit, electricity sales is modeled mathematically considering depth of discharge, maximum capacity reduction, etc. Benefit and cost analysis methods with the modeling are proposed to decide whether the introduction of V2G systems. Additionally, the methods will contribute to derive the future production and the unit cost of electric vehicle and battery and to get the technical and economic analysis.

The outlook for the Civil Service Pension (CSP) program in Korea indicates several problems. First, the balance of the benefit among the pension recipients is not well maintained. Second, the program is running out of funds as benefit increases exceed the growth in revenues. In this article, we analyze these problems by using linear programming model and discuss the alternatives. We propose an addition of the age limit to the benefit eligibility and a reconsideration of the government subsidy's level.

This study aims to analyze whether both childcare subsidy and childcare leave policies have moderating effects on the relationship between Korean women's value of children and their intentions for subsequent childbirth. The data are used from the 2015 National Survey on Fertility and Family Health and Welfare. Both hierarchical multiple regression analysis and moderated regression analysis are used for statistical analysis. The findings from the study are as follow. First, the ideal number of children, instrumental values, and emotional values have positive effects on the intentions for subsequent childbirth after controlling for background variables(level of education, income, age, and number of children). Second, childcare leave policy has no significant effect on the intentions for subsequent childbirth while childcare subsidy policy has the negative effect. Third, only childcare subsidy policy has moderating effects on the relationship between instrumental, emotional values, and the intentions for subsequent childbirth. These results suggest that policies enhancing the value of children should be implemented in addition to traditional birth rate policies. Furthermore, new birth rate polices are needed for those married women who have a high possibility of subsequent childbirth.

For Indonesia, sustainable energy supply is an important factor to preserve the stable economic growth. One important strategy is development of renewable energy, which has not been fully exploited yet. The paper examines the potency of renewable energy in Indonesia. Currently, biomass composes 23% of total primary energy supply, while geothermal and hydropower has a combined share of 3%. But according to the overall potency of renewable energy, hydropower is found to have the highest available resource of 76 GW, followed by biomass and geothermal by 49.81 GW and 28.53 GW, respectively. Although the solar radiation is only at modest level ($4.80kWh/m^2/day$), the tropical all year sunlight can boost the competitiveness of solar photovoltaic and thermal application. As for wind energy, the average speed of 3-6 m/s requires the development of low speed wind turbine. The examination of electricity and petroleum product prices through international comparison for non-OECD countries shows fifth lowest price level for both of petroleum products and electricity for industrial use. As for household electricity price, Indonesia is placed the second among all the countries compared. The energy subsidy and price structure are examined in detail because it could be a source of hindrance to renewable energy promotion. The examination of renewable energy potency in this study could provide insights about recent development of renewable energy in Indonesia. As an outcome of policy examination, the price comparison analysis suggests Indonesia to reduce or even remove the energy subsidies in the long run. These findings can be utilized to formulate effective policies for renewable energy promotion.

Upon selecting preferred bidder in Public-Private Partnership projects, multi-dimensional procurement auction, where price factor and non-price factor are evaluated, is used. This paper tries to analyze bidding data in BTO road projects. It is shown that a winner tends to get higher score in bidding evaluation, which is partly due to increase in base score as well as fiercer competition among bidders. It turns out that score margin in non-price factor was determinant in selecting winner. Also, there was no competition when the level of bonus point was set too high. For price factor, it costs 730 million KRW per score in construction subsidy by government, while it costs 2.43 billion KRW per score in toll revenue. For non-price factor, it was estimated to cost 2.30 billion KRW. Based on the results, it was suggested that we should have appropriate level of bonus point for first initiator, change in scoring rule in construction subsidy part, adjustment of base score in evaluation.

This study is aimed at investigating optimum level of payments in the direct payment program for aquaculture extruded pellets both theoretically and practically by analyzing the effects on production and income in accordance with Green Box conditions of WTO Agreement on Agriculture. In particular, by analyzing both effects on production and income, it evaluates and compares payments affecting to the level of production and income, respectively. Analysis results indicate that the optimum level of payments in the direct payment program for aquaculture extruded pellets is determined by the growth rate of farmed fish, farming period, price and volume of extruded pellets, and additional amount of cost increase and decrease. Suppose that growth rates of farmed fish by extruded pellets(EP) and raw fish - based moist pellets(MP) are the same, it reveals the optimum level of payment should be lowered from the current level of payment. However, when the growth rate of farmed fish by EP is lower than that by MP, the optimum level of payment should be raised from the current level and total amount of payments by area should be increased as well.

The number of organic farms are increasing in European countries during last 10 years. Most European governments are giving subsidies for organic farmers as well as converting organic farms from conventional farming method. The price level of most organic products are higher than price level of conventional products in general. However, there are certainly some market demand problems in organic products in some countries. Organic farms will be increased in 2005 and 2010 for 10∼20% of the total agricultural area in some European countries. Government subsidy payment is also increasing. Therefore, many farmers are going to change into organic farming method from conventional farming. However, there will be certainly some market demand problems in future because of national economic growth problems. At the same time, the quality of soil can be improved and status of health of urban consumers should be improved by consuming organic products.

The introduction of virtual power plants is actively being discussed to solve the problem of grid acceptability caused by the spread of distributed renewable energy, which is the key to achieving carbon neutrality. However, a new business such as virtual power plants is difficult to secure economic feasibility at the initial stage of introduction because it is common that there is no compensation mechanism. Therefore, appropriate support including subsidy is required at the early stage. But, it is generally difficult to obtain the cost model to determine the subsidy level because of the lack of enough data for the new business model. In this study, a survey of domestic experts on the requirements, appropriate scale, and cost required for the introduction of virtual power plants is conducted. First, resource composition scenarios are designed from the survey results to consider the impact of the resource composition on the cost. Then, the cost estimation model is obtained using the individual cost estimation data for their resource compositions using logistic regression analysis. In the case study, appropriate initial subsidy levels are analyzed and compared for the virtual power plants on the scale of 20-500MW. The results show that mid-to-large resource composition cases show 29-51% lower cost than small-to-large resource composition cases.
