Due to the recent climate change realization (timing, rainfall pattern changes), the flow regime is changing according to the watershed. The long-term change of flow regime is causing a significant change in structure and function of aquatic ecosystems. However, there is no analysis from the viewpoint of the aquatic ecosystem including flow rate alteration and ecological characteristics as well as the climate change connection in Korea yet. Therefore, We quantitatively assessed the impact of present-future flow regime alteration due to climate change on the Pseudopungtungia nigra habitat in the Mankyung river and floodplain area. As a result, it was confirmed that extreme hydrological conditions such as flood and drought are intensified in the future than the present. Especially, the changes of flow regime characteristics were clarified by comparing and analyzing the magnitude, frequency, duration, rate of change, and by linking flow regime characteristics with physical habitat analysis, it could be suggested that climate change would significantly increase the risk of future ecological changes.

Tidal regime change with general hydrolic condition change is examined, according to Garolim Tidal Power Plant (TPP) operation. Numerical model has been developed for the Yellow and East China Seas region, in order to consider the tidal regime change by the TPP operation. The changes of tidal elevation and tidal current inside the Garolim bay are also investigated in details, along with examining the change of the tidal flat area with operation. The field measurement for the tide and current have been carried out for the validation of the numerical model and for understanding the state of current system in the present state.

The wave of democratization that started in southern Europe spread to South America and Asia, dismantling the Soviet Union and Eastern European countries and appeared as a Jasmine revolution in countries of North Africa and the Middle East. As a result, many scholars have actively carried out researches related to the sudden change of North Korea, while taking a cautious view that the Jasmine Revolution might occur in North Korea. The focuses of the studies were on the cause and timing of the sudden change and the main forces of the revolution in North Korea. There weren't enough discussions on how the process will be developed and whether there will be a system change. In this study, based on the results of analyzing the systematic changes of the Jasmine revolution nations, it suggested five scenarios that can be developed after the sudden change of North Korea. Scenario type I: Relatively peaceful and the possibility of regime change, Scenario type II: Reunification and then civil war, Scenario type III: Regime changed but one of Kim Il Sung family grabbing the power, Scenario type IV: Successful regime change but civil war happening, Scenario type V: Regime change failed and civil war continuing.

On May 9, 2018, regime change took place in Malaysia. It was the first regime change that took place in 61 years after independence in 1957. The regime change was an unexpected result not only in Malaysian experts but also in political circles. Moreover, the outcome of the election was more shocking because the opposition party was divided in this general election. The regime change in Malaysia was enough to attract worldwide attention because it meant the collapse of the oldest regime in the modern political system that exists, except North Korea and China. How could this have happened? In particular, how could the regime change, which had not been accomplished despite opposition parties' cooperation for almost 20 years, could be achieved with the divided opposition forces? What political implications does the 2018 general election result have for political change and democratization in Malaysia? How will the Malaysian politics be developed in the aftermath of the regime change? It is worth noting that during the process of finding answers, a series of general elections since the start of reformasi in 1998 tended to be likened to a series of "tsunami" in the Malaysian electoral history. This phenomenon of tsunami means that, even though very few predicted the possibility of regime change among academia, civil society and political circles, the regime change was not sudden. In other words, the regime in 2018 was the result of the desire and expectation of political change through a series of elections of Malaysian voters last 20 years. In this context, this study, in analyzing the results of the election in 2018, shows that the activation of electoral politics triggered by the reform movement in 1998, along with the specific situational factors in 2018, could lead to collapse of the ruling government for the first time since independence.

This paper studies and evaluates the present situation of three decades of 'Minjoonojoundong' in Korea with a long-term perspectives. It had grown up during 1987 labour regime era and has declined abruptly since 1998. The backdrop of this decline was the transformation of labour regime from the 1987 regime to the dependent neoliberal one. The Korean labour movement did not respond to the changed structural conditions as it sustained its old strategies, militant unionism. Now the 'Minjoonojoundong' in Korea has met three difficult problems that are connected with each others. They are militant economism, political economism and formal industrial unionism. However the 'Candlelight Revolution' occurred in 2016 winter has opened a chance of regime change that could strengthen the 'Minjoonojoundong'. The revolution was primarily a political one. But it also created a dramatic situation change in labour politics. The candle-citizen demanded radical change of the polarized Korean society and overflown contingent workers. So it is a time of radical and overall innovation for the 'Minjoonojoundong' and KCTU. And they have to keep the long-term strategical vision of labour regime change.

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 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.

Through the analysis of many experimental post-dryout data, it is shown that the most probable flow regime near dryout or quench front is not annular flow but churn-turbulent flow when the mass flux is low. A correlation describing the initial droplet size just after the CHF position at low mass flux is suggested through regression analysis. In the post-dryout region at low pressure and low flow, it is found that the suggested one-dimensional mechanistic model is not applicable when the vapor superficial velocity is very low, i.e., when the flow is bubbly or slug flow regime. This is explained by the change of main entrainment mechanism with the change of flow regime. Therefore, the suggested correlation is valid only in the churn-turbulent flow regime ( $j_{g}$ $^{*}$＝0.5~4.5).).

Korean Innovation Systems are in transition from catch-up regime to post catch-up regime. This paper tries to analyse the change of scientific and technological practices in the public sector of Korea Innovation Systems. This paper focus on the way public sector scientific and technological practices are regulated and contribute to private sector. It is argued that self-governing practice of public S&T community is being enhanced and the requests of private sector for the public sector's contribution through research activity are reinforced in emerging post catch-up regime.
