Since markup is defined as price over marginal cost by Hall(1988), the New Keynesians have intensively applied its definition in elucidating the relationship between market structure and business cycle. In lots of literatures markups proved to be counter cyclical empirically and theoretically. At the same time many studies analysed the determinants for markup in relation with business cycles. This paper establishes the markup equation based on the constant returns to scale production function including intermediate goods with technology being assumed to be AR(1) process and estimates the industrial markups in the Korean 5 service industries over the period 1975:1-2010:4. The paper also analyzed the markup determinants using the autoregressive distributed lag scheme ADL(1,1) in which the dependent variable and the single explanatory variable are each lagged once.

This paper is to set up the empirical model in order to estimate industrial markup and to analyze the determinants for industrial markup by estimating the factor price elasticities of markup in the Korean manufacturing industries using the autoregressive distributed model. The import price elasticities of markup were estimated to be -1.025, -0.176, and -0.260 respectively in Machinery products, Chemical products, and Metallics which proved to have higher ratios of imported intermediate goods to industrial output. The interest elasticities of markup were also estimated to be -0.165, -0.147, and -0.210 respectively in Chemical products, Metallics, and Machinery products which are capital-intensive industries. Thus, the paper suggests that both import price index and interest rate have had more decisive effects on the changes in industrial markup in the Korean manufacturing industries, in particular, since the foreign currency crisis beginning in late 1997.

In Korea, the transportation & telecommunication service industry is composed of public sector entities, such as public transportation and the postal service, and private sector entities. The public sector may be regulated in terms of pricing or is guaranteed a normal profit. Markup can be a subject for regulation. This paper is to set up the markup equation, estimate the industrial markup, and analyze the markup determinants by estimating the factor price elasticities of markup in the Transportation & Telecommunication industry. The factor price elasticities of markup were estimated to be -0.07 in wage rate, -0.45 in import price index, and -0.13 in interest rates. We suggest that import price and interest rate are major factors to be considered first of all in regulating the transportation & telecommunication industry.

This study investigates the effects of real exchange rate (RER) on firm level mark-up and export. Using firm level data in Daegu-Gyeongbuk manufacturing industries during 2006-2013, we find that firms adjust their markup in response to the RER changes and this adjustment is heterogeneous with respect to firm and industry characteristics. In particular, an increase in markup following the RER depreciation is greater for firms with lower intermediate input import and higher industry concentration. However, productive firms in this region increase their export, instead of markup, during the RER depreciation. This implies that the productive firms in the region may not retain significant market power: They do not change the final price in local currency to increase selling volume during the RER depreciation (the export price in foreign currency decreases).

This paper is to set up the autoregressive distributed lag model in order to estimate factor elasticities of the service export in the medical and healthcare service industry and to analyze the determinants for its export performance during 1975-2015. The empirical results suggest that industrial markup, exchange rate, and interest rate have had more decisive effects on the industrial export performance in the medical and healthcare service industry, in particular, during the declining period in factor prices since the foreign currency crisis beginning in late 1997.

This paper is to estimate the total factor productivity(TFP) in the Korean manufacturing and service industries during the period 1975:1-2016:4 using the stochastic frontier analysis model. In order to analyze the determinants for the total factor productivity the paper estimates the industry-specific determinant elasticities of TFP using the autoregressive distributed model. The industry-specific determinants, which reflect the industrial structure and properties include markup, the ratio of capital to labor(KL), and the ratio of foreign intermediate goods (FIG) to industrial output. The average value for total factor productivity growth was estimated to be 0.0199 in manufacturing and 0.0063 in the service industry. The markup and KL elasticities of TFP were estimated to be 2.481 and 0.651 in manufacturing respectively and -1.403 and 0.042 in the service industry respectively. The empirical results suggest that the industrial markup and the ratio of capital to labor have had decisive effects on the changes in the total factor productivity in the Korean manufacturing and service industries during the period 1975:1-2016:4.

해운업은 국민경제의 기간산업으로 타산업에 대한 파급효과가 큰 고부가가치 산업이며, 동시에 제4군으로 국방기능을 수행하는 국가안보산업이다. 글로벌 금융위기 이후 해운업 침체가 지속됨에 따라 세계 주요국들은 자국의 해운선산에 대해 강력한 지원 및 보호정책을 시행하고 있다. 중국과 덴마크, 독일, 프랑스의 경우 자국 해운사에 대한 대출 및 융자보증 등의 지원을 확대하고 있으며, 선박투자회사 및 선박 대출기관 설립, 보조금 지원 등 다양한 방식을 통해 해운업을 지원하고 있다. 다음은 현대경제연구원이 발표한 "주요국 해운업 지원 정책과 시사점"의 주요 내용을 요약 정리한 것이다.

컴퓨터의 발전과 더불어 자료의 표현 및 저장 방법도 매우 다양해지고 있다. XML은 인터넷의 확산으로 많은 분야에서 연구되어지고 있는 마크업 언어가 되었다. 이처럼 다양한 분야에서 활용되는 XML을 데이터를 관리하는 데이터베이스에 사용되는 것은 당연할 것이다. XML 문서를 데이터베이스에 저장하는 방법에는 파일 시스템으로 저장하는 방법, 관계형 데이터베이스에 저장하는 방법, 개체지향 데이터베이스에 저장하는 방법, XML 전용 데이터베이스에 저장하는 방법 등이 있으며 이들에 대한 연구가 계속되고 있다. 본 논문에서는 XML 문서를 XML이 아닌 다른 형태로 변환하여 저장하는 방법으로 가장 많이 활용되는 관계형 데이터베이스와 XML 문서 형태를 그대로 저장하는 XML 전용 데이터베이스를 비교 분석하는 연구를 하였다.

Motion capture technology is widely used to make a realistic motion in these days. So, motion capture data is required to exchange between many animators in a work group. But different motion capture devices have different motion rapture data formats. Thus it is difficult that a animator reuse and exchange motion capture data in a storage. In this paper, we proposes a standard format for integrating a different motion capture data format. In addition, we proposes a framework of a system that manage motion capture data using our standard format. Our standard format is called MCML(Motion Capture Markup Language). It is a markup language for motion capture data and based on XML(extensable Markup Language). Our system to manage motion capture data consists of a several component - MCML Converter, MCML , MCML Editor, Motion Viewer.
