Any market has its own entry barriers to foreign firms. In this reason, foreign firms. who are entering to a foreign market, must have internal competence which can contribute to overcome the entry barriers and have the capability for adjusting to external environment of foreign market. In this paper we analyzed the rate of entry barriers of external environment of Russian market when Korean firms entering into Russia. In this paper we segmented the external environment that affects to foreign firms as entry barriers such as competitive, socio-cultural, and political-legal environment and analyzed the rate of barriers induced from these environmental factors to foreign firms. The applied method is correlation and multiple regression analysis. The result of empirical analysis is a follows: The competitive environment of local(Russian) market dose not affect to Korean firms as an entry barrier. The local socio-cultural environment, however, significantly affect to foreign firms as entry barrier and negatively affect to sequential entry to sequential entry of Korean firms, and among sub-factors hierarchical behavior of governmental workers, in particular, raises unstability and uncertainty of external environment and negatively affects to Korean firms' investment in the future.

Environmental Regulation Effects Revisited: Channel Effects on Industrial Economic Performance

( Yun Seop Hwang ),( Xiaoxu Dong ),( Wonwoong Choi ) 한국생산성학회 2016 生産性論集 Vol.30 No.2

This paper theoretically reviews the researches about the effects of environmental regulations on economic performances. According to the previous researches, we propose that environmental regulations affect industrial economic performances through three channels: export, foreign direct investment, and innovative activities. We collected the related data over the period of 1997-2009 from 14 industries in Korea. The emission amounts of the eight kinds of pollutants were used to calculate the pollutant index as the measure of stringency of environmental regulations. We used the simultaneous equations model and the 3SLS method to solve the endogenous problems between the variables. The results indicated that environmental regulations negatively affect industrial economic performances through export channels. Environmental regulations have insignificant effects on inflow FDI. Although environmental regulations motivate companies to increase R&D investments, it does not influence industrial economic performances through R&D investments. In the future, Korean government should implement various policies of environmental regulations, reinforce economic policies and soft policies to enhance efficiency and flexibility.

Does oil price rise necessarily reduce export?: Focused on Korean exports

( Yun Seop Hwang ),( Young Jun Choi ) 한국생산성학회 2012 生産性論集 Vol.26 No.4

This paper analyzes the effects of oil price change on the value of exports of Korea. The general convention is that the effect of oil price raise is leading to reducing the exports. The change in oil price is related to the change of production costs as well as changes in macroeconomic indices, such as price level and interest rate. Those changes in production costs and macroeconomic indices may affect the performance of exports. However, we found that the oil price increase is not necessarily reducing the exports based on Korean industrial exports data. Rather, in our analysis, the rise of oil price lowers the real interest rate and thus the increase in oil price leads to an increase in the value of Korean exports. It is also found that oil price affects the export directly and indirectly through the real interest rate.

Design of a Multi-Threaded Image Signal Processor with a Multi-Bank Cache Memory

Yun-Seop Hwang,Jun-Mo Jeong 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.9

This paper proposes a multi-thread architecture-based Image Signal Processor (ISP). As the required image quality is gradually increasing in today’s society and the image processing algorithms are becoming more diversified, the burden of calculations in the main processor such as CPU is growing bigger. To solve these problems, an ISP was designed in order to reduce the burden on the main processor by applying the multi-thread architecture and applying various image processing algorithms, allowing a high performance processing. The proposed ISP has a multi-bank cache memory that can perform the multi-thread data and instructions with a hit-save-FIFO and latency hiding unit. The proposed ISP was verified with Virtex-7 FPGA and showed about 2.4 times higher processing speed compared to the conventional DSP.

Is BTC Oil Pipeline Good or Bad for Azerbaijan Economy?

Yun Seop Hwang,김수은,최영준 한국환경경제학회 2010 자원·환경경제연구 Vol.19 No.2

Since 2000, as importance of sourcing energy emphasized caused by instability of international oil price, interests toward Caspian countries as an alternative markets has increased. Especially, Azerbaijan, as middle Asian emerging exporting country, has performed drastic economic boom because of massive amount of foreign capital flowed in and construction of BTC pipeline. However, despite this economic surge, there are unbalanced economy which is merely focusing on energy industry and pressure from increase in real exchange rate and inflation. In order to analyze the sustainability of Azerbaijan economy, the total sample time period of this paper is from January 2001 to December 2007 and the term is divided into before and after BTC line construction. Vector Error-Correction Model has been applied to analysis confirming short-term and long-term effect. As a result, Azerbaijan now face the symptoms of the recession during the time period and this is due to high oil price and increase in export influenced by BTC oil pipeline resulting in decrease in real interest rate. This conclusion is to affect competitiveness of manufacturing industry, base industry for economic proliferation, in a negative way. 2000년 이후 국제유가의 불안정성으로 인한 에너지 자원 확보의 중요성이 강조되면서 에너지 자원의 대안 시장으로 카스피해 연안국가들에 대한 관심이 고조되고 있다. 특히 아제르바이잔은 중앙아시아 신흥석유 수출국으로서 해외자본의 유입, BTC 송유관 개통 등으로 인해 급속한 경제성장을 이루었다. 그러나 높은 경제성장에도 불구하고 경제구조가 에너지 산업에 집중되는 등 경제구조의 불균형을 보이고 있으며, 최근 실질환율 상승의 압박 및 인플레이션이 가속화되고 있다. 아제르바이잔 경제의 지속가능성을 파악하기 위해 본 연구에서는 분석대상기간을 2001년 1월부터 2007년 12월까지의 전체 표본기간, BTC 개통을 기점으로 BTC 개통 이전과 이후의 기간 등 세 단계로 구분하였으며, 벡터오차수정모형을 이용하여 분석을 시도하였다. 실증분석 결과, 아제르바이잔은 분석기간 동안 경기침체 증상을 보였으며, 이는 고유가의 영향과 BTC 송유관 개통으로 인한 수출의 급증이 아제르바이잔 실질환율을 하락(평가절상)시키는 주원인임을 확인하였다. 이러한 결과는 장기적인 경제발전의 기반이 될 제조업의 경쟁력에 부정적 영향을 미칠 것으로 예상된다.

Design of SIMT Architecture-based Reconfigurable Image Signal Processor

Yun-Seop Hwang,Kwang-Yeob Lee,Jun-Mo Jeong 한국정보통신학회 2015 2016 INTERNATIONAL CONFERENCE Vol.7 No.1

This paper proposes SIMT architecture-based reconfigurable Image Signal Processor (ISP). Conventional ISP commonly has the hard-wired image processing algorithm of which the processing speed is fast, but one problem of these conventional ISP is that they cannot apply various image processing algorithms. On the other hand, as the image quality required by various devices is gradually increasing and the image processing algorithms are becoming diversified, the burden of calculations in the main processor such as CPU or GPGPU is growing bigger. To solve these problems, an ISP was designed in this paper which can reduce the burden of the main processor by applying the SIMT structure which is based on instructions, can apply various image processing algorithms, and allows parallel processing. The proposed ISP was verified with a VC-707 board equipped with Virtex-7 FPGA and showed about 2.4 times higher processing speed compared to the DSP which performs a similar role as ISP.

황윤섭(Yun-Seop Hwang),최영준(Young-Jun Choi) 한국무역학회 2008 무역학자 전국대회 발표논문집 Vol.2008 No.8

Both energy price and energy consumption are important factors for explaining the economic growth, but there are few researches that consider these two factors simultaneously. It seems that these factors are negatively correlated and may cause multicollinearity problem. Using multi-level model, in this paper, we would analyze both the effect of oil price and oil consumption on Korean economy by industry level. Each industry has it's own oil consumption pattern and shows different growth trend under the effect of oil price. This paper has some practical advantages. First, this paper employs the advanced multi-level model which enables us to analyze oil price and consumption simultaneously in one model. Second, we can show not only overall effect of oil price but compare the effect industry by industry. This result would give some important implications for both policy makers and industry participants. Finally, this model can be extended to other research topics, such as industry specific factors are important and different industry to industry.
