This paper aims to clarify the characteristics of 'the regime 87', the product of democratic transition of Korea in 1987, and its historical evolution. Through the clarification, this paper expects to provide a discoursive basis for reforming the regime 87 and advancing democracy in Korea. For this purpose, this paper seeks to find Korea within the context of macro-historical change of the world. And then this paper tries to analyze the reason and the process of the birth of the regime 87 and its historical evolution.

Intellectual Property Rights (IPR) system is one of the major institutions for incentivizing innovation. However, a strong IPR regime does not necessarily encourage innovation every time. This is because a variety of factors come into play in configuring the ways the IPR system interacts with the dynamics of innovation. In the present study, we examine whether different degrees of absorptive capacity at the industry level bring about heterogeneous effects of a strong IPR regime on the innovation capability of innovators across different industries in developing country. Using the case of the 1986 IPR reform in Korea, which permitted patenting pharmaceutical products and copyrighting computer programs, we analyze the quality of patents produced by Korean applicants between 1982 and 1991. Our analysis finds no evidence that the IPR reform improved the innovation capability of innovators in the two aforementioned sectors, but rather affected their patenting behavior differently.

Gas submerged jet is an outstanding thermohydraulic phenomenon in pool scrubbing of fission products during a severe nuclear accident. Experiments were performed on the hydraulic characteristics in the ranges of air mass flux 0.1-1400 kg/m²s and nozzle diameter 10-80 mm. The results showed that the dependence of inlet pressure on the mass flux follows a power law in subsonic jets and a linear law in sonic jets. The effect of nozzle submerged depth was negligible. The isolated bubbling regime, continuous bubbling regime, transition regime, and jetting regime were observed in turn, as the mass flux increased. In the bubbling regime and jetting regime, the air volume fraction distribution was approximately symmetric in space. Themelis model could capture the jet trajectory well. In the transition regime, the air volume fraction distribution loses symmetry due to the bifurcated secondary plume. The Li correlation and Themelis model showed sufficient accuracy for the prediction of jet penetration length.

Generally, regime shift occurs less frequently than policy change and/or government change. Regime shift needs alterations and changes along the three critical components which constitute a domestic regime: (1) the character of the socioeconomic coalition that rules the country; (2) the political and economic institutions through which power is acquired and exercised; and (3) the public policy profile that give political direction to the nation. This paper tries to examine characteristics of the welfare regime of Korea, and explore policy reform options for the welfare regime shift in Korea. From the viewpoint of livelihood security perspective, I firstly tries to examine development process of Korean welfare regime and specify the main characteristics of that regime. Secondly, I present three policy reform options: (1) reform of the formal political institutions such as electoral system and government type; (2) restructuring of the composition of government expenditure structure; and (3) reduction of the informal employment. These three policy reform options are related to the alteration of socioeconomic coalitions and the changes of the political and economic institutions. Instead of concluding remarks, I finally suggest two debate topics to the round table discussion.

This paper presents a wear analysis procedure for calculating the wear of journal bearings during the start-up and coast-down cycles of a motoring stripped-down single cylinder engine operating with a tilted shaft. In order to decide whether the lubrication state of a journal bearing is in the mixed-elasto-hydrodynamic lubrication regime, we utilize lift-off speed and MOFT (most oil film thickness) under mixed-elasto-hydrodynamic lubrication regime at the corresponding aligned shaft. We formulate an equation for the modified film thickness in a misaligned journal bearing considering the additional wear volume described in Part I of this study. For this, we use the calculation results of the degree of misalignment and tilting angle obtained after finding the eccentricities of the two bearings supporting the crankshaft of a single cylinder engine. In this Part II, we calculate the wear of journal bearings using the fractional film defect coefficient, the asperity load sharing factor, and the modified specific wear rate for the application of mixed-elasto-hydrodynamic lubrication regime. We show that the accumulated wear volume after turning the ignition switch on and off once, increases to ${\sigma}=39{\mu}m$ and then decreases from ${\sigma}=39{\mu}m$ with increasing in surface roughness.

An adjoint-based error estimation and mesh adaptation study is conducted for two-dimensional viscous flows on unstructured hybrid meshes. The error in an integral output functional of interest is estimated by a dot product of the residual vector and adjoint variable vector. Regions for the mesh to be adapted are selected based on the amount of local error at each nodal point. Triangular cells in the adaptive regions are refined by regular refinement, and quadrangular cells near viscous walls are bisected accordingly. The present procedure is applied to single-element airfoils such as the RAE2822 at a transonic regime and a diamond-shaped airfoil at a supersonic regime. Then the 30P30N multi-element airfoil at a low subsonic regime with a high incidence angle (${\alpha}=21deg.$) is analyzed. The same level of prediction accuracy for lift and drag is achieved with much less mesh points than the uniform mesh refinement approach. The detailed procedure of the adjoint-based mesh refinement for the multi-element airfoil case show that the basic flow features around the airfoil should be resolved so that the adjoint method can accurately estimate an output error.

The rise of the Robo-advisor represents one of the most profound shifts in FinTech. It also raises concerns about their financial management. As the most Robo-Advisors utilize ETFs, we seek to determine the appropriate risk management model in estimating 95% Value-at-Risk (VaR) and 99% VaR in this paper. The GARCH and the Markov regime wwitching GARCH are evaluated in terms of the accuracy of probability, the independence of extreme events occurrence and both. The result shows that the Markov regime switching GARCH can be a good ETF risk management tool since it can reflect financial market structural changes into the volatility.

With the advent of high energy/power lasers, extreme conditions, such as those found in astrophysical environments, can be reproduced in laboratory. The scaling between laboratory and astrophysical environments, especially for viscosity and resistivity that govern dissipation processes, is not perfect. Yet, the similarity is close enough to make laboratory experiments relevant for astrophysics. The results have been encouraging, in the sense of suggesting the possibility of exploring fundamental physical processes at play in astrophysical phenomena. In this talk, I will review a few successfully performed and ongoing experiments, such as those for turbulence and magnetic field generation in fluid regime and collisionless shock wave in plasma regime.

This study deals with President Park Chung-hee's greed for dominance and oppression during the Yushin Regime in the 1970's and consists of case studies related to anti-democracy of the National Council for Unification Subject, illegality of President's emergency rule and oppression in the process of putting down Buma Uprising. The National Council for Unification Subject was an organization for presidential selection and institutionalized by the enactment of Yushin constitution. Emergency rule was carried into effect as a means to repressing college students and forces out of office for the president's long-term seizure of power. And Buma Uprising rose against violence in resistance to the Yushin regime and president Park Chung-hee's greed for dominance and oppression. These case analyses applied the aspects of causal relationship(birth and fall of Yushin Regime), legal system(Yushin constitution and president's emergency rule) and behavior(President Park's greed for dominance and oppression) for this study. The National Council for Unification Subject institutionalized through Yushin constitution and the Yushin regime formed by emergency rule enabled President Park to cling to long-term seizure of power by means of greed for dominance and oppression. After all, his failure to keep the spirit of the time and stepping stone for democratic constitutional government triggered Buma Uprising, a kind of anti-Establishment movement, and caused the fall of the Yushin regime.
