  • The decision-making by agents in games is commonly based on reinforcement learning. To improve the quality of agents, it is necessary to solve the problems of the time and state space that are required for learning. Such problems can be solved by Macro-Actions, which are defined and executed by a sequence of primitive actions. In this line of research, the learning time is reduced by cutting down the number of policy decisions by agents. Macro-Actions were originally defined as combinations of the same primitive actions. Based on studies that showed the generation of Macro-Actions by learning, Macro-Actions are now thought to consist of diverse kinds of primitive actions. However an enormous amount of learning time and state space are required to generate Macro-Actions. To resolve these issues, we can apply insights from studies on the learning of tasks through Programming by Demonstration (PbD) to generate Macro-Actions that reduce the learning time and state space. In this paper, we propose a method to define and execute Macro-Actions. Macro-Actions are learned from a human subject via PbD and a policy is learned by reinforcement learning. In an experiment, the proposed method was applied to a car simulation to verify the scalability of the proposed method. Data was collected from the driving control of a human subject, and then the Macro-Actions that are required for running a car were generated. Furthermore, the policy that is necessary for driving on a track was learned. The acquisition of Macro-Actions by PbD reduced the driving time by about 16% compared to the case in which Macro-Actions were directly defined by a human subject. In addition, the learning time was also reduced by a faster convergence of the optimum policies.

  • This paper overviews different exit strategies for the U.S. from the debt-overhang, and analyses their implications for emerging markets and global stability. These strategies are discussed in the context of the debates about secular-stagnation versus debt-overhang, the fiscal theory of the price level, the size of fiscal multipliers, prospects for a multipolar currency system, and historical case studies. We conclude that the reallocation of U.S. fiscal efforts towards infrastructure investment aiming at boosting growth, followed by a gradual tax increase, aiming at reaching a modest primary fiscal surplus over time are akin to an upfront investment in greater long-term global stability. Such a trajectory may solidify the viability and credibility of the U.S. dollar as a global anchor, thereby stabilizing Emerging Markets economies and global growth.

  • The vast majority of the disaster prevention design research in Korea has focused on the macro-level interventions such as examining the existing systems and approaches, instituting revised policies, systematically establishing intervention programs, and evaluating the effectiveness of the interventions. However, little has focused on systematically challenging individuals' awareness using micro-level intervention. The present paper introduces approaches to micro-level intervention by infusing narrative-based simulation, and further suggests the implications on balancing the approaches of both micro-level and macro-level interventions.

  • Purpose - The objective of this study is to investigate what motivates global FDI inflows in the different economic development level and to clarify the FDI motivation type in the level of qualitative economic growth. Design/methodology/approach - Major macroscopic social·economic factors induced FDI inflows were analyzed using fixed-effect panel regression with 30-year panel data of 28 countries from 1985 to 2014. For analysis in the stage of economic growth, two category of developed and developing countries was used. And to analyze FDI motivation type in the level of qualitative economic growth, 4 shares of GDP; consumption·government·investment expenditure and export, was used as explanatory variable. Findings - In developed country, TFP(total factor productivity) and GDP have a great influence on FDI inflows, and consumption and labor compensation have a slight effect. This result indicates that the market seeking-driven, horizontal type investment is shown along with efficiency seeking investment. In developing country, human capital and TFP is shown to have greater impact on FDI inflows and labor compensation, exports, investment and government expenditures also have impacts. Thus it has confirmed that not only efficiency-seeking vertical investment for using low cost well educated laborer, but also government-driven economic growth and export policies could affect the FDI inflows. Research implications or Originality - The FDI investment decision making of multinational companies is decided by their own purpose. But, in the concept of as follows; 1) FDI is a long-term capital flowing for maximization of economic utility with limited global resource, 2) Thus FDI could be affected by macro socio·economic factors of host country. 3) Also such macro factors is different by each economic growth qualitative level. Therefore macro socio·economic factors of each country could be affected by the qualitative level of their own economic growth. To attract FDI inflows, it is desirable to implement differentiated incentive policies in the qualitative level of economic growth. Furthermore in developing countries it is recommended to implement government driven economic growth policies as follows; fostering well educated human resources, improving technology productivity in the relative lower cost labor market compared to developed countries and boosting international export volume.

  • The study aims to explore the alternatives through case analysis in the UK, which is quickly responding with appraisal policies and guidelines appropriate to the digital age. Through a theoretical study, it was confirmed that the concept of appraisal in the digital age was extended to decisions on which records to be created and acquired, and in this context, that the value of records needed to be determined at the earliest point in their life cycle. Furthermore, the advantages of macro-appraisal methods and the inevitability of expanding appraisal groups were outlined. Based on this discussion, the change in the British public record appraisal policy was discussed from a policy perspective, and the current British public record appraisal system was analyzed. Based on the analysis of various policy statements and guidelines, general appraisal criteria, 60 operation selection policies and appraisal processes were discussed. As a conclusion, this study discusses various alternatives to appraisal policies in the digital age.

  • This study examined whether family-friendly policies at work moderate the association between fathers' gender role attitudes and their affectionate parenting behaviors. The data was derived from the Panel Study of Korean Children. The samples included 1,164 fathers who participated in the seventh and eighth panel studies. To analyze the data, Pearson's correlations, multi-regression, and simple slope analysis were conducted using SPSS 25.0 and PROCESS Macro. The key findings of the study were as follows: Among family-friendly policies, the paternity leave and a flexible work system moderated the association between gender role attitudes and affectionate parenting behavior. Such family-friendly policies strengthened fathers' affectionate parenting, and gender role attitudes tended to be egalitarian in this case. The results of the present study showed that fathers' affectionate parenting behavior reflected their egalitarian gender role attitudes and particularly emphasized the importance of the role of family-friendly policies in providing fathers with autonomous time use.

  • The purpose of this study is to map mineral and coal (Minerba) policies by analyzing the law and producing research novelty on mineral and coal governance policies in Indonesia with the Theory U approach. This study uses a qualitative research with the U theory approach. The results of the SNA analysis indicate that good mineral and coal governance must be carried out at various levels, from micro to macro. First, related to regulations on mineral and coal governance at the macro level. Regulations regarding the management of mineral and coal need to be carried out with a deeper evaluation related to the tax system, licensing system, increased value added and downstreaming and mineral and coal funds. The second is related to the regulation of mining management in the meso level. Third, related to the management of mineral and coal at the micro level, it is necessary to conduct more stringent supervision of the impacts caused by the mining sector of the Minerba. In addition, surveillance is also carried out as per law in order to avoid harmful behavior for both the company and the state. The originality of this research is the theory of U in the Mining Law research.

  • As consumers are increasingly shopping online for fashion products, their return behavior is also increasing. Regarding the factors affecting return behavior, this study explores the effect of the purchasing orientation considering returns that are derived from bracketing purchase behavior, monetary lenient return policies, and non-monetary lenient return policies. Additionally, this study examines the effect of monetary/non-monetary lenient return policies on return behavior, mediated by the purchasing orientation considering returns. This study was conducted through an online survey and 238 data were collected and used for analysis. Two research models were designed for each independent variable of monetary lenient return policies, and non-monetary lenient return policies, and the path of the research model was analyzed using Process Macro 4.0. The study found that the sub-dimensions of return policy - monetary or non-monetary return policies - had different effects on return behavior through purchasing orientation considering returns. Monetary lenient return policies had a positive direct effect on return behavior, and purchasing orientation considering returns mediated the effect of the monetary lenient return policies on return behavior. However, the non-monetary lenient return policies only positively and significantly directly affected return behavior. The findings of this study contribute to understanding consumers' purchasing orientation considering returns. Furthermore, from the effect of the return policy on return behavior, the results are valuable as they can help fashion marketers establish a return strategy.

  • More than 20 years after introducing the public records management system in Korea, the criteria and methodologies for archival appraisal and selection are still unclear. Modern archival appraisal theories have developed in two orientations, such as provenance and pertinence. This study aims to investigate the methodological implications of each theoretical orientation of archival appraisal and to suggest some directions for improving the appraisal practices and policies. Firstly, archival appraisal theories are analyzed according two orientations. Secondly, four methodologies are derived from combining the macro/micro dimension and theoretical orientations. Thirdly, the methodological orientations of the criteria for selecting permanent records presented in the Public Records Management Act are analyzed. Finally, based on these analyses, appraisal policies and practices for selecting the records with permanent value are proposed to be improved.
