A number of tin-containing elastomers are produced commercially by Korea Kumho Petrochemical Co., Ltd. (KKPC) under the Kosyn Sol tradename. The effect of mastication of commercial and laboratory polymerized S-SBR has, been investigated using chemical mixer(ML-500), NMR, GPC and Mooney viscometer. Mastication of polymers containings coupling bonds is affected by the amount of stearic acid, the temperature of mixing and the time length of mixing.
The Determining Factors of Kimchi Premium in the Cryptocurrency Market
오정훈 국제e-비즈니스학회 2019 e-비즈니스 연구 Vol.20 No.2
This paper, exploring the remarkable roles of exchange rates, discovers three determining factors of Kimchi premium when a cryptocurrency is adopted and commonly used as another type of currency in the foreign exchange market. In order to examine its movement, we describe the price of a cryptocurrency as the relative price in terms of a standard currency using the exchange rate formula. Then, we identify three determinants of the Kimchi premium from the equilibrium condition in the foreign exchange market: the gaps in the rates of return of the cryptocurrency, the interest rates of the standard currencies, and the expected cryptocurrency exchange rates.
Does IT improve the productivity of other sectors?
오정훈 국제e-비즈니스학회 2007 e-비즈니스 연구 Vol.8 No.4
The emergence of new information technology and its rapid diffusion are based on the belief that the investmenton IT has enormous potential for improving the productivity of firms as well as individuals. In this paper, by comparing the results from two different models, we reexamine the impact of IT on the Korean economy. It was shown that, although the aggregate output growth istaking place in Korea because of the emergence of new IT goods and services, the Korean economy is not yet of an IT friendly structure, which improves other industries’ production technology in accordance with the development of IT.
The Effects of Government Forms on Exchange Rate Devaluations in Developing Countries
오정훈,황태희 연세대학교 동서문제연구원 2014 동서연구 Vol.26 No.1
Despite voluminous literature regarding economic determinants of exchange rate policies, very little attention has been given to the effects of the formal criteria of constitution. Moreover, political determinants have been mainly used to explain the exchange rate regime choices in specific regions. The purpose of this paper is to show how the presidential system affects the exchange rate devaluation decisions as one of the formal constitutional features. The results suggest that the presidential system provides the incumbents with more room for incurring the political costs of devaluation. Moreover, the newly elected presidents are less likely to be vulnerable to costly devaluation. The underlying mechanism emphasized in this paper is the flexibility of election possibility. Electoral concerns present different incentives to incumbents in the sense that the incumbents with fixed terms (presidentialism) are less vulnerable to costly policies than the ones with flexible terms. The results also suggest that the strength of government is positively related to devaluation decisions. In particular, strong presidential governments substantially increase the probability of devaluations.

한국원자력연구소에서 2001년도에 구축 완료한 이용자 중심의 MIS 연동 웹 기반 전자도서관시스템을 통해 나타난 기대효과를 정리하면 다음과 같다. 첫째, 도서관만의 독립적인 정보관리시스템보다는 MIS 시스템간의 연동을 통해 시너지 효과를 창출할 수 있다는 점. 둘째, 거시적 관점에서의 기관 차원에서 보면 동일 또는 유사한 데이터의 이중 입력을 줄일수 있어서 그로 인한 잉여인력을 활용할 수 있다는 점. 셋째, 이용자 정보를 비롯한 과제정보, 회계정보 및 연구실적정보 등을 포함한 제반 정보를 MIS DB와 연동시킴으로써 이용자 편의도모는 물론 입력 데이터에 대한 신뢰도를 높일 수 있다는 점. 넷째, 전자도서관시스템과 MIS 시스템간의 DB 공동활용으로 인해 현재 개발 중이거나 향후 개발할 KMS 시스템의 기반을 확고히 다질 수 있다는 점 등을 들 수 있다.
