In this paper, we propose a new framework for detecting the unauthorized dumping of garbage in real-world surveillance camera. Although several action/behavior recognition methods have been investigated, these studies are hardly applicable to real-world scenarios because they are mainly focused on well-refined datasets. Because the dumping actions in the real-world take a variety of forms, building a new method to disclose the actions instead of exploiting previous approaches is a better strategy. We detected the dumping action by the change in relation between a person and the object being held by them. To find the person-held object of indefinite form, we used a background subtraction algorithm and human joint estimation. The person-held object was then tracked and the relation model between the joints and objects was built. Finally, the dumping action was detected through the voting-based decision module. In the experiments, we show the effectiveness of the proposed method by testing on real-world videos containing various dumping actions. In addition, the proposed framework is implemented in a real-time monitoring system through a fast online algorithm.

This study was conducted to develop a Web-GIS based monitoring module of smart city that can effectively respond, manage and improve situation in all stages of illegal dumping management on a city scale. First, five technologies were set for the core technical elements of the module configuration. Five core technical elements are as follows; video screening technology based on motion vector analysis, human behavior detection based on intelligent video analytics technology, mobile app for receiving civil complaints about illegal dumping, illegal dumping risk model and street cleanliness map, Web-GIS based situation monitoring technology. The development contents and results for each set of core technical elements were evaluated. Finally, a Web-GIS based 'illegal dumping monitoring module' was proposed. It is possible to collect and analyze city data at the local government level through operating the proposed module. Based on this, it is able to effectively detect illegal dumpers at relatively low cost and identify the tendency of illegal dumping by systematically managing habitual occurrence areas. In the future, it is expected to be developed in the form of an add-on module of the smart city integration platform operated by local governments to ensure interoperability and scalability.

This study aims to analyze the WTO-inconsistent aspects of the single rate presumption of the United States in establishing and imposing anti-dumping duties for non-market economy exporters. By examining the drafting history in the GATT/WTO negotiations and the practice of the single rate presumption for non-market economies by the United States from a comparative perspective, it critically addresses the inherent lack of pertinent disciplines under the framework of the WTO Anti-Dumping Agreement in establishing dumping margins for exporters of non-market economies. The WTO Dispute Settlement Body leaves open the possibility of allowing the investigating authority to consider multiple exporters and the exporting country as a single entity. However, the study argues that it is difficult in practice for the investigating authority to make a single-entity decision in a WTO-consistent manner. The study also finds an incompatibility in the notion between establishing dumping margins for 'individual' exporters and 'non-market economies.' A proper discipline for non-market economies under the multilateral anti-dumping norm needs to be reconsidered in the era of persistent trade conflicts between the United States and China.

This paper focuses on the impacts of waste dumping on inorganic nutrients in the dumping area of the Yellow Sea, and the effect of an governmental regulation of pollution in dumping areas. The environmental variables and parameters of the dumping and reference areas in the Yellow Sea were measured during July 2009 and analyzed. In addition, the analyzed data for inorganic nutrients over the last 10 years were obtained from the Korea Coast Guard (KCG) and the National Fisheries Research and Development Institute (NFRDI). The chemical environment of the study area revealed increases in concentrations of inorganic nutrients, Chemical Oxygen Demand (COD), and Volatile Suspended Solids (VSS) in the bottom layer. On the contrary, the pH level was decreased. Most notably, the time series data of inorganic nutrients showed gradual increase over time in the dumping area, and thus, the oligotrophic waters trend toward eutrophic waters. The increases appears to be due to the disposal of large amounts of organic waste. In recent times, the wastes disposed at the area were largely comprised of livestock wastewater, and food processing waste water. The liquefied waste, which contains an abundance of nutrients, causes a sharp increase in concentrations of inorganic nitrogen in the dumping area. On the one hand, the dumping sites have been deteriorated to such an extent that pollution has become a social problem. Consequentially, the government had a regulatory policy for improvement of marine environmental since 2007 in the dumping area. Hence, the quality of marine water in the dumping site has improved.

As China is one of WTO member nations, It has an obligation to have to certainly keep a standard regarding anti-dumping systems deciding in WTO agreements. Nonetheless the Chinese anti-dumping laws is causing legal uncertainty because of insufficient details regulations about the account of dumping margins, the termination of an investigation in case of negligible imports, and sunset review And a part of regulations are disagreed with WTO anti-dumping agreement about price undertakings. Therefore, South Korea should indicate them and urge the Chinese government to revise them so that its anti-dumping Law is agreed with WTO agreement. Aside from this, if the anti-dumping investigation is initiated, South Korea government must observe how the Chinese authorities operates its anti-dumping law that do not agree with WTO agreement, and should prepare the countermeasure accordingly. The analysis of this study is concentrated on the compatibility of the WTO anti-dumping agreement with China's interpretation of the antidumping policy and public law. Also, Including our export company, government agencies, academic circles being related, and international trade advisory agencies must expand opportunity of information sharing.

China having largest market in the world, has been criticized by its trading partner countries due to its unfair trade practices, particularly in the field of anti-dumping regulation. The main reasons for such criticism seem to come from the incomplete anti-dumping law as instrument to protect the industry concerned. In 2001, though new anti-dumping law was established to replace the former one by revising it to meet the needs for economic development which should be secured for china to take part in the competition world as the new member of WTO. The provisions concerned have been evaluated not to be sufficient and efficient from the viewpoint of the safeguard mechanism, while are required to be modified to meet the real world of international trade law. I consider that as the biggest partner of chinese trade activity, we will need to maintain a well understanding of the Chinese anti-dumping regulations. So this report conducts the Chinese anti-dumping regulations, compares between the chinese regulations and the WTO agreement, and studies deeply in to the problems and the improvements of the Chinese anti-dumping regulations.

Analyzing EU trade laws and institutional systems, the trade policy of EU has been founded, undoubtedly, on common interests for EU members. EU trade policy leaves room for 'Collective Protectionism' by permitting legal persona or interesting group to raise anti-dumping procedures. The anti-dumping policy of EU has shown a protectionism itself and has been affected by political motives. Investigation against anti-dumping can easily open and also there exists a wide range of political involvements. Furthermore, anti-dumping policy could be misused for protecting declining industries, which lost comparative advantage in global market. Economic theories show that anti-dumping measures divert import from outsider into insider members, which finally results in increasing intra-production of EU. This is exactly the reason why the anti-dumping policy has become attractive trade policy.

In this paper, we developed the algorithm which tracking the vehicle and deciding the moment of dumping in landfills. We first trace the position of vehicle using the difference image between current image and background image and then we decide the stop point from the shape of vehicle route and detect the dumping point by comparing the dumping image with the image that vehicle is stopping.

In CCTV environments, a lot of learning image data is required to monitor illegal dumping of garbage with a typical image-based object detection using deep learning method. In this paper, we propose a system to monitor unauthorized dumping of garbage by learning the articular points of the person using only a small number of images without immediate use of the image for deep learning. In experiment, the proposed system showed 74.97% of garbage dumping detection performance with only a relatively small amount of image data in CCTV environments.

Anti-dumping instruments among trading partners have been the subject of research by both academicians and practitioners. This study attempts to establish an early-warning model of anti-dumping against Chinese textile exporting companies, which have suffered from anti-dumping regulations and got arbitration awards. After reviewing theories of anti-dumping arbitration, early-warning and relationship marketing, the measuring items and relationship marketing model of Chinese textiles exporters are investigated. Empirical methods are selected based on early-warning theories of companies. Eighty percent of 156 valid questionnaires by surveys and interviews are used as training data via Binary-Logistic regression while the other twenty percent are validated in the model. As a result, a proper early-warning model has been established.
