Although tariffs are falling due to the establishment of WTO and the increase of FTA agreements, Non-tariff measures such as trade remedies, trade technology barriers (TBT), sanitary quarantine (SPS) and customs regulations have become trade barriers, limiting free trade. Korea, which has achieved export-led economic growth, should present countermeasures. As Non-tariff measures are complex and are applied in different countries, Customized countermeasures by type, industry and country should be presented. To this end, non-tariff DB should be established. In order to collect, analyze, and present measures for non-tariff measures, a dedicated organization dedicated to the government is essential. And consultation among the other parties on non-tariff measures is important, and activities are important at the WTO committee. In addition, it is necessary to foster expertise and expertise in non-tariff organizations. Existing research shows non-tariff measures in each country. As existing studies have been analyzed through studies based on the non-tariff measures of each country or reports of international organizations, there are limitations in the identification of regulations and comparative analysis between countries. Therefore, this paper analyzes on the basis of non-tariff measures DB of WTO I-TIP.

The objective of this study is to investigate the effect of unrelated diversification on earnings management, and then to analyze the moderating effect of Audit Committee on the relationship. The sample of this paper consists of 206 firms and 1,924 firm-year data listed on Korea Exchange from 2000 to 2009. The results are as follows. First, unrelated diversification is positively associated with earnings management. Second, there are the moderating effects of Audit Committee establishment and independence on the relevance between Unrelated-diversification and earnings management. These findings imply that it is important to strengthen the effectiveness of Audit Committee in unrelated diversification firm.

13명의 환자에 있어서 새로운 비관혈적 방법에 의한 심박출량을 계산하고, 열희석에 의한 방법으로 측정한 심박출량과 비교하였다. 본 논문에서 사용한 비관혈적 펄스 전달 방법은 대동맥 모델에서의 최적 매개변수 방법을 사용하였다. 모델의 최적 매개변수는 맥압의 첫번째 고주파 전달함수에서 측정치와 계산치의 차이를 최소화하는 조건에 의하여 계산하였다. 전달함수의 2개의 펄스는 각각 경동맥동과 대퇴동맥에서 Piezo-resistive Pulse Microphone을 사용하여 측정하였고, 대동맥의 직경은 초음파 방법을 사용하여 측정하였다. 13명의 환자에게서 16가지 측정을 해서 열희석과 비관혈적 방법은 0.89의 상관계수를 보여주었다.

To improve the monitoring of Coastal Debris in the South Korea, which is difficult to estimate due to limited resources and vertex-based surveys, an approach based on UAV(Unmanned Aerial Vehicle) images and the RT-DETR(Realtime DEtection TRansformer) model was proposed for detecting Coastal Debris. By comparing to field investigation, the study suggested the possibility of quantitatively detecting coastal garbage and estimating the total capacity of garbage deposited on the natural coastline of the South Korea. The RT-DETR model achieved an accuracy of 0.894 for mAP@0.5 and 0.693 for mAP@0.5:0.95 in training. When applied to unmanaged coasts, the accuracy for the total number of coastal debris items was 72.9%. It is anticipated that if guidelines for defining monitoring of unmanaged coasts are established alongside this research, it should be possible to estimate the total capacity of the deposited coastal debris in the South Korea.

This study analyzes how investors' irrational behavior (or pessimistic sentiment) affects stock market returns and investors' market activity using mass media that delivered public information from January 1998 to December 2012 as a sample. According to pessimistic investor theory, investor pessimism leads to downward pressure on the price of equity capital, thereby making market sentiment pessimistic and lowering market yields. It also shows that investor pessimism increases transaction costs in the market, which in turn dampens investors' trading activities. In other words, pessimistic reporting on public information disseminated by mass media induces investors to act irrationally, eventually having a direct impact on the stock market. This study conducted an empirical analysis of the existing theoretical and empirical studies using domestic mass media as a sample. First, the study revealed a negative correlation between pessimistic reporting and returns as well as excess returns, while it did not show statistically significant results. Second, evidence has been suggested that pessimistic sentiment in the stock market has a negative impact on future pessimistic reporting by mass media. Third, the analysis of the impact of pessimistic reporting on investors' market activity using proxy variables for various market activities found that pessimism dampens market activity, while it did not show statistically significant results. It is assumed that low statistical significance is due to the fact that sample collection was carried out on a monthly basis. While the results of the study have low statistical significance, statistical signs support predictions of the theory.
