차세대 고속철도 기술개발 사업을 통해 개발된 통합차상신호 시스템은 국내에서 운영중인 세가지 신호시스템인 ATP, ATC, ATS의 신호를 모두 처리하면서 열차 운행의 중단 없이 열차 운행구간을 이동하게 된다. 현재 통합차상신호시스템의 신뢰성과 안정성 확인을 위해 차세대 고속철도 시제차인 HEMU-430X에 탑재하여 시운전을 진행중에 있는데, 시운전이 여객열차의 영업운전 사이에 진행되기 때문에 다양한 실험과 검증에 많은 제약이 따른다. 이러한 제약 사항을 해결하고 다양한 실험과 개선 활동을 위해 통합차상신호시스템을 실험실내에서 테스트할 수 있는 통합차상신호시스템용 시뮬레이터의 개발이 필요하게 되었고, 본 논문에서는 통합차상신호시스템용 시뮬레이터 개발에 관한 내용을 다룬다.

우리나라 폐업의 대부분을 차지하고 있는 소상공인들은 서비스 또는 제품의 노출 부족으로 운영에 어려움을 겪고 있고 이는 높은 폐업율로 이어지고 있다. 상대적으로 규모가 작은 소상공인들은 비용, 시간, 인력 등의 문제로 활발한 마케팅 활동을 펼치지 못하고, 지역적인 상권내에서 전통적인 오프라인 영업에 의존하고 있는 실정이다. 현재 우리나라 검색 시장의 대부분을 차지하고 있는 네이버와 구글의 경우 소규모 사업자들이 적극적으로 온라인 마케팅을 펼칠수 있도록 자신들의 검색엔진최적화 가이드를 만들어서 제공하고 무료 교육도 실시하고 있으며, 각종 SNS 서비스 제공 회사들도 자사의 서비스 확대나 광고 수익을 올리기 위해 자세한 매뉴얼을 제공하고 있음에도 여전히 많은 소상공인들은 온라인 마케팅 채널 운영과 검색엔진최적화를 하지 못해 자신의 서비스나 상품을 잘 노출시키지 못하고 있다. 이에 본 연구는 서비스업 소상공인의 배경적 특성과 기술지향성이 온라인 마케팅 채널 운영과 검색 엔진 최적화라는 조절변수를 거쳐 경영성과에 어떤 영향을 미치는지를 분석하고 이를 통해 서비스업 소상공인들의 매출 증대를 위한 온라인 마케팅 확산에 도움이 되고자 한다.

This paper examines the effects of dominating large shareholders and foreign blockholders on credit ratings. An effective governance mechanism is expected to lead to higher credit ratings through its impact on default risk of the firm. Our results show that dominating large shareholders have an adverse impact on credit ratings of domestic firms on the level of its statistical significance. Foreign shareholders are positively associated with credit ratings, contributing to the higher credit worthness of domestic firms.

In contrast, the Japanese firms found that the higher(lower) the debt ratio is, more up(down)side through its actual activities (operating cash flows, manufacturing costs, discretionary costs) rather than accruals. This study establishes the academic basis for the decision-making of Korean-Japanese firmss by using the sample of each country to check what kind of decision-makers are making earnings managements at the present time when the relationship between Korea and Japan has suffered due to export restrictions.

This paper investigates whether managerial ownership and foreign ownership have impacts on firm value, using a sample of logistics firms listed on the Korea Stock Exchange between 2008 and 2014. In the Korean economy, family-controlled business groups, known as chaebol, constitute a unique governance system. To acquire investments from controlling shareholders, a logistics firm is likely to be included in family-controlled business groups. Since reform of the governance structure of logistics firms in the South Korea enables shareholder value to be maximized, we analyzed ownership effects on firm value using pooled ordinary least squares. Empirical results showed that there was a significant positive relation between managerial ownership and firm value. This study also found that there was a significant positive relation between foreign ownership and firm value. We thus show that both managerial ownership and foreign ownership can protect shareholders by positively affecting firm values.

The export on visual and game industry has grown very rapidly and is expanding its role in economic growth. In contrast, researches on these firms' financial performances in strategic and policy point of view are difficult to be found regarding the export of cultural industry. In this study, we analysis the effects of firms export in cultural industry on their financial performances focusing on game and visual industry. We find that the recent activities of export in game industry have positive effect on firm's growth in game industry. However, we find that the export deteriorate the net profit.

In this study, how international diversification of domestic companies increases corporate profits and increases the dividend income of paid-in capital investors, who provided the basis for corporate business activities in the process of distributing profits. I tried to find out if it had an effect. An empirical analysis was conducted using a fixed-effect model for companies with settlements at the end of December listed on the domestic securities market from 2011 to 2018. It was confirmed that the higher the level of international diversification of individual companies, the higher the company's dividend payout ratio and dividend yield. This means that companies can steadily expand corporate profits and dividend yield of shareholders by securing new overseas markets through international diversification, it can be seen that a company's international diversification strategy can contribute to the increase of corporate value by increasing the company's dividend payout ratio by increasing dividendable profit.
