배경 : 개흉술 후 생기는 급성 호흡 부전 증후군은 아직까지 그 원인과 경과가 자세히 알려져 있지 않다. 이에 저자들은 개흉술 후 생기는 급성 호흡 부전 증후군이 발생한 환자들을 대상으로 원인 및 유병률, 경과, 치료 성적등을 알아보고자 하였다. 대상 및 방법 : 1996년 1월부터 2001년 8월까지 흉강경 수술을 포함한 총 개흉술 4018례중 급성 호흡 부전 증후군이 발생한 32명의 환자들을 대상으로 후향적 분석을 하였다. 결과 : 총 4018례 중 32례에서 급성 호흡 부전 증후군이 발생하여 전체 발생 빈도는 0.8%였다. 전폐 절제술이 245례 시행되었으며 이중 13례(5.3%)에서 급성 호흡 부전 증후군이 발생하였고, 폐엽 절제술이 710례 중에서 9례(1.3%), 식도 절제술이 226례 중에서 10례(4.4%) 발생하였다. 32명의 환자 중 31명(96.9%)이 악성 종양으로 수술한 환자였고, 1명은 아스페르길루스종으로 수술한 환자이다. 발병원인을 알 수 없는 경우가 21례(65.6%)로 대부분을 차지했으며, 최초 발병일은 평균 수술 후 7.4±7.0일이었다. 최초 병변 발생 부위는 우하엽부분이 10례(31.2%), 좌하엽 부분이 9례(28.1%)였고 양하엽 부분이 12례(37.5%)로 31례(96.9%)가 하엽 부분에서 병변이 시작 되었다. 수술 후 4일 이전에 발생한 급성 호흡부전 증후군 환자군에서 그 이후에 발생한 환자군보다 통계적으로 유의하게 수분 과다 투여가 관찰되었다.(p<0.05). 총 32례 중 21례가 사망하여 사망률은 65.6%였으며 복와위와 질소가스 환기등 적극적인 치료를 시작한 1998년 7월 이전과 이후의 사망률은 각각 100%, 47.6%로 통계적으로 유의한 사망률의 감소를 보였다.(p<0.05) 결론 : 개흉술 후 발생하는 급성 호흡 부전 증후군은 악성 질환으로 폐엽 절제술, 전폐 절제술, 식도 절제술과 더불어 광범위한 임파절 절제술이 동반되는 경우에 그 빈도가 높았다. 수술 직후 발생한 급성 호흡 부전 증후군의 경우 수술 중 수분의 과다 투여가 관찰되었으며 복와위, 질소 가스 환기 등 적극적인 치료로 사망률을 낮출 수 있었다.

In this paper, we study for measurements of 3-dimension position of the object with CCD Camera and Laser Beam. And we present the algorithm for calibrations of the plane equation and normal vector of the object using image processing and optical characteristics of CCD Camera and Laser Beam. Also, we present the algorithm to transform 2-dimension position information into 3-dimension position information. To confirm presented algorithms, we design measurement-module and confirm this algorithm through experimentation using the module.

Military Rescue Operation for the Hostages Taken by Somali Pirates: Was the Korean Navy’s“ Daybreak in the Gulf of Aden” Legitimate?

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.

Haunting Phantom on the Way to the Korean Reunification? The Chinese People's Volunteer Army in the Korean War and Its Legal Questions

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.

This study solves the inverse kinematics problem of industrial FANUC robot. Because every joint angle of FANUC robot is dependent on the position of end-effector and the direction of approach vector, arm metrix T_6 is very complicated and each joint angle is a function of other joint angles. Therefore, the inverse kinematics problem can not be solved by conventional methods. Noticing the fact that if one joint angle is knows, the other joint angles are calculated by the algebraic methods, θ_1 is calculated using neumerical analysis method, and solves inverse kinematics problem. This proposed method, in this study, is more simpler and faster than conventional methods and is very useful in the real-time control of the manipulator.

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.

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.
