This study is to develope a user-based economic valuation methodology and model for the economic analysis on the DDS of foreign journals. For this study, the sampling data on the annual subscribed journals by K institution was used and the online questionnaire was used to collect data. There are three aspects of the economic value of DDS journals was classified as use value, non-use value, and expectancy value. We suggested the income and market approach to measure its economic use value. To estimate the its value by individual users, this study applied a contingent valuation method and designed the imaginary scenarios.

Presently, the online game industry of Korea are growing up fastly. The growth of online game give rise to the new problem of regulation on Real Money Trade(RMT). This article analyzed the market failure of RMT, and showed whether or not the government regulate RMT. The results showed that the RMT has efficiency in monopoly and external economie, and inefficiency in external diseconomies and uncertainty. But, the inefficiency in external diseconomie and uncertainty is based on the regulation of RMT by the game company. So, it is necessary for government to deregulate the RMT for curing the inefficiency of RMT.

In this paper, we investigated a Value-at-Risk approach to the volatility of two crude oil markets (Brent and Dubai). We also assessed the performance of various VaR models (RiskMetrics, GARCH, IGARCH and FIGARCH models) with the normal and skewed Student-t distribution innovations. The FIGARCH model outperforms the GARCH and IGARCH models in capturing the long memory property in the volatility of crude oil markets returns. This implies that the long memory property is prevalent in the volatility of crude oil returns. In addition, from the results of VaR analysis, the FIGARCH model with the skewed Student-t distribution innovation predicts critical loss more accurately than other models with the normal distribution innovation for both long and short positions. This finding indicates that the skewed Student-t distribution innovation is better for modeling the skewness and excess kurtosis in the distribution of crude oil returns. Overall, these findings might improve the measurement of the dynamics of crude oil prices and provide an accurate estimation of VaR for buyers and sellers in crude oil markets.

This article is aiming intensively to analyze the polarizing tendency of labour market and social integration. The polarization of labour market is being regarded as one of the hottest issues not less important than those problems of economic growth, employment, income distribution and national security etc. in the national policy. In this article, we will first follow up the important phenomena of labour market polarization and the background as well as its consequence. Especially, it asks if the present labour policy in the new government which is now being concentrated on the improvement of employment rate(from the present 63% to the 70% in the future) could deserve to diminish the polarization of labour market in korea. At one side, this article makes the special attention on the diversifying tendency of labour market and the various phenomena of fragmentation and segmentation in the labour market according to the forms and types of employment and according to the employee's status as much as the company's size. At the other side, it emphasizes that to overcome the polarization of labour market should require the wide reform from the legal measure to the improvement of the wage system, and the qualification system and the social investment as well as the human resource development. Furthermore, this article stresses the importance of integrative approach between the active market policy and the social policy instead of choosing each policy option, seperatively.

계속적인 충·방전이 가능하여 반영구적으로 사용이 가능한 2차 전지는 친환경 소재로 주목받고 있으며, 노트북 컴퓨터와 휴대전화, 캠코더 등 소형 전자기기뿐만 아니라 전기자동차의 핵심소재이다. 전기자동차 시장의 성장과 더불어 중대형 에너지 저장용 2차 전지 시장의 규모는 더욱 확대되고 있어 관련된 소재의 개발 경쟁과 관심이 날이 갈수록 뜨거워지고 있다. 따라서 소재개발 측면에서 2차 전지 핵심 소재의 물성 발현의 원리 등을 이해하고 최적 소재 설계를 위해서는 원자 레벨에서의 소재 설계 접근법이 필요하다. 따라서 실험적인 연구가 어려운 부분과 원자단위에서의 물질 현상에 대한 이해 그리고 연구 개발의 효율성 증진을 위해서 전산재료과학(computational materials science) 기술이 광범위하게 활용될 수 있다. 본 기고문에서는 리튬이온전지에서의 전극 소재에 대한 전산재료모사의 활용과 연구동향에 대하여 소개하고자 한다.

서비스마케팅문헌을 살펴보면 지각된 서비스품질 및 이에 대한 고객반응에 초점을 맞추어 이루어진 연구들이 많이 있다. 그러나 본 연구에서는 지각된 서비스품질이 실질적으로 서비스 구매자인 소비자의 재구매 행위와 어떤 인과관계가 있고 또한 로열티와는 어떤 인과성을 갖는지를 규명하는데 주력하였다. 아울러 이러한 인과성이 조절변수인 라이프스타일에 따라 어떤 차이가 발생하는지를 규명하고자 하였다. 지각된 서비스품질을 측정하는 있어서는 기존 SERVQUAL방식의 측정개념이 아닌 Johnson, Tsiros & Lancioni(1995)가 적용한 일반적 시스템 접근법(투입, 과정, 성과변수로 측정)을 활용하여 새롭게 접근하고자 노력하였다. 연구결과 지각된 서비스품질은 이를 구성하는 선행변수(투입요소와 과정 및 성과요소)와 긍정적인 정(+)의 인과관계를 나타내고 있으며, 특히 성과요소에 의해 서비스품질이 지각되는 경향이 매우 큰 것으로 분석되었다. 또한 지각된 서비스품질은 재구매 의사와 로열티에 긍정적인 영향을 미치고 있는 것으로 검증되었으며 이러한 모든 인과관계는 소비자들의 라이프스타일 유형에 따라 다르게 나타나고 있었다. 따라서 서비스산업에 있어 마케팅전략을 수립하는데 있어서도 유형적 제품과 마찬가지로 라이프스타일을 이용한 시장세분화 전략을 활용할 필요가 있다.

Both export and import sides of grain trade market are analyzed and compared in terms of the static levels and dynamic trends to make new empirical inference on the imperfect competition degree. Export concentration level is high compared to import concentration level. And such states have been sustained since 2001 until 2014. Unlike public concerns, the concentration level of export side seems to be easing by small degree. However, the grain trade market remains imperfect competitive market. Furthermore, overall imperfective competition condition over 2002-2014 has been worsened compared to 2001 level. It is because the reduction level of imports concentration is higher than that of the export concentration. Gini and Atkinson Inequality Index based on Lorenz Curve are newly utilized to analyze market concentration level, instead of the commonly used concentration ratio.
