A cold & hot rolling coil production line of iron mill consists of a kind of coherent automatic process, but an automatic labelling process still had technical difficulties in the automation of its process. The reason for difficulties in building an automatic process is that quantitative data for each rolled coil from every shipping is not easy to receive from the previous process. It is not possible to apply for a general and simple purpose robot that is actually worked through a taught position to the process because the size and direction of the coil has differed on every shipping. From these reasons, we introduce a robot vision system to accept an expected variable situation and to ensure the stability and flexibility of the process. This paper examines a study applied for similar cases and finds the position and direction of rolled coil using the moment invariant algorithm proposed by Hu. In addition, the camera calibration and position error compensation algorithm is applied by the analysis of the relationship of transition in a space coordinate system. The construction of a robot vision system proposed by this paper is a more intellectual system than that of the automatic labelling system, which is already used to the Daihen steel mill of NEW JAPAN steel mill co.ltd in Japan, and shows a better independent operation in the field of production.

The objective of this development project is to localize an automatic molten metal supplier that has been distributed by WESTOMAT, Germany. throughout the world. To achieve this purpose, an energy-saving pressurized dosing furnace and molten metal differential pressure control system that is able to automatically supply a determined quantity of aluminum molten metal were developed. The localized equipment was installed in a site. Also, the results of the test operation of this equipment can be summarized as follows: It was able to improve the productivity because there were small decreases in supplying speeds and small losses in wastes compared to the existing mechanical molten metal supplier. Also, it was able to minimize the cost in maintenances due to the direct application of high temperature molten metals to molds. In addition, there were small energy losses due to the use of high thermal insulators compared to the existing reverberating furnace and able to prolong the life-time of furnaces and produce good quality nonferrous metals because it represented small carbon refractories and alumina in applied molten metals. Furthermore, it demonstrated no particular differences by objectively comparing it with the product by WESTOMAT.

On January 21, 2011, the Korean navy commandos rescued the twenty-one crewmenabducted and detained by Somali pirates in the Indian Ocean. The pirates capturedalive were brought to Korea for trial and the prosecutor’s office of Pusan sentencedthe leader of the Somali pirate group to life-imprisonment. The other four piratesreceived imprisonment terms from 12 to 15 years. Regardless of these domestic legalpunishments, this rescue operation has raised a few critical international legalquestions. The primary objective of this paper is to answer these questions. Thisresearch analyzes the international legal characteristics of the Korean Navy’s rescueoperation. Then, a few case-studies of military rescue operation are carried out inorder to justify the Korean Navy’s rescue operation. The Korean Navy’s rescueoperation may be regarded as an act of forcible self-help and realization of existinginternational legal right.

Although relationships among the former belligerent parties of the Korean War have changed drastically over the decades, the parties still remain under the armistice system because the Korean War is not over legally. The primary purpose of this research is to analyze questions related to the Chinese People's Volunteer Army in the Korean War from an international legal perspective. As a new topic, this is intended to be a precautionary examination of an issue that could haunt the eventual process of peacemaking on the Korean peninsula. The main text of this article consists of three parts. The first examines whether the Chinese People's Volunteer Army's entering the Yalu River was self-defense under Article 51 of the UN Charter. The second part covers various legal questions relating to armed hostilities in the Korean War under international law. The third part discusses the legal questions around an armistice negotiation.

The Proliferation Security Initiative was launched in 2003 by the Bush administration right after the So San incident. Its primary purpose is to interdict the spread of WMD and their delivery systems. Due to the provocative and challenging characteristics of the Initiative, which are inconsistent with conventional international law, there are some objections against the Initiative. This paper answers the highly topical questions regarding the Initiative in three parts. The first part addresses the origin and development of the Initiative. The second part critically analyzes the background of the Initiative such as the neoconservative ideology of the Bush administration and its world strategy, international terrorism, and the U.S. arms industry. The third part scrutinizes questions concerning the preemptive use of force for self-defense and the interdiction of foreign vessels on the territorial and high seas. The Initiative is also examined from a viewpoint of customary international law.

Trans-Pacific Partnership (TPP) as a US Strategic Alliance Initiative under the G2 System: Legal and Political Implications

이용중 (사) 이준국제법연구원 2015 Journal of East Asia and International Law Vol.8 No.2

“The rise of China” is a critical issue of the twenty-first century’s world politics. China is leading the new bipolar system in the post-Cold War period with the US. As the American dominance in East Asia became weaker, the old containment could not be fully implemented anymore. As a result, a new comprehensive strategic initiative covering the whole Pacific coastal States is being adopted. The outcome of this transformation is the Trans-Pacific Partnership (TPP), which was reached on October 5, 2015. This article aims to analyze the newly arisen TPP as a post-Cold War strategic alliance of East Asia. The TPP is a mega regional trade agreement. Its predictable legal setting is thus indispensable for the peaceful coordination of competition between both sides. The TPP could be a firm ground for the stability of this region, sharing the vision of cooperation, not confrontation in the future.
