The Global Economic Crisis, Dual Polarization, and Liberal Democracy in South Korea

This paper aims at a theoretical reflection on and an empirical analysis of the relationship between the global economic crisis and liberal democracy in South Korea. For this, we elaborate the concept of dual polarization and construct a model of path analysis which includes such variables as socio-economic and political-ideological cleavage, political party affiliation, ideological orientation, economic (crisis) outlook, and support for an autocratic presidential rule as potential threats to liberal democracy. Descriptively, the paper examines how liberal democracy has unfolded and where South Korea stands today with regard to the quality of her democracy. Analytically, the paper examines where the potential threat to liberal democracy comes from based on a general population survey in Korea from 2014. The major findings of our analysis include: 1) The support for autocratic presidential power is stronger among citizens than among MPs. 2) Political party affiliation, ideological orientation, and economic (crisis) outlook are closely interrelated and significantly affected by the political-ideological cleavage. All independent variables contribute to explaining support for an autocratic presidential rule. 3) Yet there also exists strong support for a democratic regime among both MPs and citizens

Reusable, polyethylene glycol-structured microfluidic channel for particle immunoassays

A microfluidic channel made entirely out of polyethylene glycol (PEG), not PEG coating to silicon or polydimethylsiloxane (PDMS) surface, was fabricated and tested for its reusability in particle immunoassays and passive protein fouling, at relatively high target concentrations (1 mg ml-1). The PEG devices were reusable up to ten times while the oxygen-plasma-treated polydimethyl siloxane (PDMS) device could be reused up to four times and plain PDMS were not reusable. Liquid was delivered spontaneously via capillary action and complicated bonding procedure was not necessary. The contact angle analysis revealed that the water contact angle on microchannel surface should be lower than ~60°, which are comparable to those on dried protein films, to be reusable for particle immunoassays and passive protein fouling

Development of an ex vivo model for the study of cerebrovascular function utilizing isolated mouse olfactory artery

OBJECTIVE: Cerebral vessels, such as intracerebral perforating arterioles isolated from rat brain, have been widely used as an ex vivo model to study the cerebrovascular function associated with cerebrovascular disorders and the therapeutic effects of various pharmacological agents. These perforating arterioles, however, have demonstrated differences in the vascular architecture and reactivity compared with a larger leptomeningeal artery which has been commonly implicated in cerebrovascular disease. In this study, therefore, we developed the method for studying cerebrovascular function utilizing the olfactory artery isolated from the mouse brain. METHODS: The olfactory artery (OA) was isolated from the C57/BL6 wild-type mouse brain. After removing connective tissues, one side of the isolated vessel segment (approximately -500 µm in length) was cannulated and the opposite end of the vessel was completely sealed while being viewed with an inverted microscope. After verifying the absence of pressure leakage, we examined the vascular reactivity to various vasoactive agents under the fixed intravascular pressure (60 mm Hg). RESULTS: We found that the isolated mouse OAs were able to constrict in response to vasoconstrictors, including KCl, phenylephrine, endothelin-1, and prostaglandin PGH(2). Moreover, this isolated vessel demonstrated vasodilation in a dose-dependent manner when vasodilatory agents, acetylcholine and bradykinin, were applied. CONCLUSION: Our findings suggest that the isolated olfactory artery would provide as a useful ex vivo model to study the molecular and cellular mechanisms of vascular function underlying cerebrovascular disorders and the direct effects of such disease-modifying pathways on cerebrovascular function utilizing pharmacological agents and genetically modified mouse models

ADADA 2016 14TH international Conference for Asia Digital Art and Design Association - Relationship between perceived value in Omni-Channel Shopping and repurchase intention

Along with the development of ICT, the distribution strategy of existing companies has been changing to the ‘Omni-Channel’ strategy. According to the diversification of distribution channels, the value of customer shopping has also been changing. Consumers that shop within various distribution channels want to acquire benefits through new and diversified experiences. Thus, it is important to perform studies on whether continuous purchase is possible by continuing from values that are being satisfied by certain elements of the Omni-Channel by grasping the cognition of consumers. This study identifies the characteristics of Omni-Channel consumption, perceived usefulness through the ease-of-use by consumers, and relationships with repurchase intention. This study provides a theoretical basis to activate the Omni-Channel which may satisfy the demand of consumers by setting causal relationship between each element by conducting a survey
