We evaluate the income-led growth policies introduced in the first year of 'the Moon Government', and try to find ways to extend policy packages. We emphasize the expansion of fountain effects, reinforcing trickle-down effects, and fiscal expansion. Nevertheless, we still face two deep problems. It is hard to reverse the long-run downward growth trend due to population decline. It is also hard to overcome the chronic inefficiency in resource allocations originated from the Korea-specific monopolistic structure. We still can take advantage of income-led policy, but the growth effect will be limited if our efforts just remain in mild improvement of income distribution. We have to challenge the broader reform agenda if we really aim at great paradigm shift.

The Korean government has provided various policy devices to boost technology transfers between academia and industry since the establishment of the Technology Transfer Promotion Act in 2000. Along with the enactment of the law, the Korean government mandated the establishment of a technology transfer office at national and public universities and encouraged technology transfer activities. Despite the quantitative expansion of technology transfer offices (TTOs), operational inefficiency was brought up. As a supplementary policy, the Korean government implemented a line of projects to support the labor and business expenses of leading TTOs. This research questions whether the project greatly affected the technical efficiency of TTOs. We analyze publicly available university panel data from 2007 to 2015 using a one-step stochastic frontier analysis. The results suggest that the program was marginally effective at shifting the technical efficiency distribution to the right on average, but it failed to maximize its impact by diversifying the policy means based on targets. The marginal effects of the program on technical efficiency differ according to the research capability and size of each school. We also compare technical efficiency against the licensing income at the start and end of the program. Technical efficiency increased for the leading TTOs, and both measures show improvements for unsupported TTOs. Our empirical results imply that diversifying the program for universities with different characteristics may have improved the effectiveness of the policy.

The purpose of this study is to examine the status and limitations of the activation plan as a result of the change in urban regeneration paradigm. In particular, the change in housing life was considered following the guidelines of the New Deal project. Specifically, the three types - General Neighborhood, Housing Support, and DongneSaligi - were analyzed from the perspective of organization, space and program. In addition, the master plan and unit project, the organization and progress, and the budget plan were reviewed. As a result, the New Deal project for urban regeneration is importance on economic regeneration, which, unlike the integrated and continuous guide proposed by the government, could limit the individual progress of transitional organizations, 2-dimensional planing and various programs. Thus, first, in order to supplement the organization's verticality and inefficiency in progress, the annual business assessment should be discouraged and the permit and progress of the project should be determined at the local government level. Second, integrated and multidimensional planning is necessary to produce synergy effects in the physical environment. Finally, the link between program unit projects and the economic effects can be considered.

The purpose of this research is to seek solutions in reducing shadow effects of construction projects on neighboring areas and as its result, we have yielded methods as below to mitigate shadow effects. To eliminate shadow effects fundamentally, revising building layouts to eliminate shadow effects by obtain construction site as much as two point two times of its height. But it will cause multiple problems such as economic inefficiency due to lack of construction sites as well as small sites that are often located in zones that are mixed with highly dense commercial and residential areas along with plan more parks on northern part of the construction site. Therefore, it is recommended to proceed Environmental affect evaluation for shadow effects and gain its residents permission prior to construction or revising building layout. In the other hand, the sunlight collector, which is one of the newly developed recycled energy, has been proven to improve illumination expected to become a reliable solution when dealing with shadow issue in and around high density residential areas.

Purpose - The purpose of this study was to examine the effects of privatization of Chinese state-owned enterprises (SOEs) on their initial returns and long-term performance after initial public offering(IPO). Design/methodology/approach - This study used 1,599 Chinese IPO firms, some of which were SOEs. The multivariate regression analyses were implemented to analyze their effects. Findings - First, the privatization of SOEs does not have any statistically significant effect on the initial return of IPO firms. Second, the shareholdings of government prior to IPOs for both privatizing of SOEs and non-privatizing firms and for both exchanges of Shanghai and Shenzhen have a statistically significant positive effect on the initial return of IPO firms. Third, the privatization of SOEs has statistically significant negative effect on the long-term returns of IPO firms. Fourth, the state-shareholdings prior to IPOs have statistically significant negative effects on the long-term return of IPO firms. Fifth, the state-shareholdings of the privatizing SOEs prior to IPOs have statistically significant positive effects on the long-term return of IPO firms. Research implications or Originality - The results imply that the higher shareholdings and ownership of the Chinese government on SOEs reduce the information asymmetry for the investors of IPO shares or maybe due to inefficiency of SOEs prior to IPOs lead to lower offer prices or higher opening prices leading to severe underpricing and relatively lower stock market returns in the long-run both for the privatizing firms and for the higher state-shareholding firms, while both factors interactively improve their long-term stock market returns.

Globally, agriculture is one of the largest consumers and polluters of water resources, contributing to the unsustainable use of limited water resources. To reduce the resource use and environmental footprints associated with current and future food systems, researchers and policy makers have recommended the transition to sustainable and healthier diets and the reduction of food loss and waste along the food supply chain. However, there is limited information on the synergistic effects and trade-offs of adopting the two measures. In this study, we assessed the water-saving potential of the two measures in South Korea using environmentally extended input-output relying on the EXIOBASE database for the reference year 2020, along with scenario analysis to model the potential outcomes. Specifically, we analyzed scenarios where meat consumption was reduced by 30% and 50% and in combination with a 50% reduction in food waste at the consumption stage for each scenario. According to our findings, by considering individual measures of dietary change and food waste reduction, shifting to a diet with 30% and 50% less meat consumption could lead to reduction in water footprint by 6.9% and 7.5%, respectively, while 50% reduction in food waste at the consumption stage could save about 14% of water footprint. However, the synergistic effects of the two measures such as 30% less meat consumption and 50% food waste reduction, and 50% less meat consumption and 50% food waste reduction result to 20% and 24% reductions in water footprint, respectively. Moreover, our findings also showed that increasing food consumption with high environmental impacts could promote resources use inefficiency when waste occurs. Thus, policy strategies that address synergistic effects of both dietary change and food waste reduction should be strengthened to achieve sustainable food system. International and national policies can increase resource efficiency by utilizing all available reduction potentials while considering strategies interactions.

This study focus on the legislative conflict for Se-Jong City In case of this paper, the law of administration agency centered is based on the conflict of legislative conflict present government at that time suggested the amendment of that legal status because of so many inefficiency and negative effects regardless of opponent asserts. Here there were a deep various political interests fundamentally both of sides. Legislative conflict here affects the regional conflict among the benefits and indirect benefits or nothing in any area. As the result, political interest deeply which was connected in politics influenced the big national issues, not to amend as a result government failure will be come.

While melting glaciers due to global warming have facilitated the development of polar routes, Arctic vessels require reliable anti-icing methods to prevent hull icing. Currently, the existing anti-icing method, i.e., the heating coil method, has disadvantages, such as disconnection and power inefficiency. Therefore, a carbon nanotube-based surface heating element method was developed to address these limitations. In this study, the numerical analysis of the surface heating element method was performed using ANSYS. The numerical analysis included conjugate heat transfer and computational fluid dynamics to consider the conduction solids and the effects of wind speed and temperature in cold environments. The numerical analysis method of the surface heating element method was validated by comparing the experimental results of the heating coil method with the numerical analysis results (under the -30 ℃ conditions). The surface heating element method demonstrated significantly higher efficiency, ranging from 56.65-80.17%, depending on the conditions compared to the heating coil method. Moreover, even under extreme environmental conditions (-45 ℃), the surface heating element method satisfied anti-icing requirements. The surface heating element method is more efficient and economical than the heating coil method. However, proper heat flux calculation for environmental conditions is required to prevent excessive design.

The Mutual Financial Cooperatives(MFCs) in Korea need to make efforts to increase efficiency and productivity in order to secure stable and sustainable growth and competitiveness. Therefore, this study analyzes the efficiency and productivity of MFCs from 2012 to 2018 and suggests some implications. The methodology employed is a Dynamic-Network Slacks-Based Measure(DNSBM) Model. The findings from an empirical study include that first, on average efficiency scores of the institutions, NH(0.225) showed the highest overall efficiency, and followed by SH(0.128) and MG(0.126). After 2015, most of the MFCs' efficiency scores had risen until to 2018. Second, in divisional analysis, the inefficiency in creating the high profitability-stage had been greater than establishing-funds-stage. Third, in projection analysis of Division 2, the inefficiency of the output factors such as interest income and operating income was severe. Fourth, the results from the Malmquist Productivity Index analysis of Division 1 of the fist-stage illustrate that all three MFCs showed minus catch-up effects. Also, a soundness from reducing bad loans and expansion of loans in combination with generating various ways of creating profits besides the interest income is urgently needed for Korean MFCs.

On the basis of a Stochastic Frontier Approach (SFA), this paper analyses revenue efficiencies for the same sample of Korean and Japanese railways in the papers which analyze cost efficiencies using a generalized translog functional form. The paper also compares the results of revenue efficiencies with cost efficiencies and evaluates the effects of managerial autonomy and privatization on the firm-specific efficiencies. The results show that the average estimate of revenue inefficiency is 7.02% when the term of inefficiency is assumed to be distributed as a half-normal and 6.98% as a exponential for the total sample. Also, standardized inefficiencies in revenues (7.5%) are greater than those in costs (2.1%). JR East and JR West are found to be most efficient on the revenue side and on the cost side respectively while JNR and JR Kyushu are worst efficient on the both sides. Finally, the correlations between efficiencies in revenues and costs also between efficiencies and privatization are positively correlated. The results suggest that the most independent companies, with increased managerial autonomy via privatization, are the most efficient in both revenues and costs.
