The Constitution of North Korea: Its Changes and Implications

Though a departure from mainstream socialist States, a glimpse of North Korea\u27s Constitution can still provide observers with an understanding of how North Korea has undergone and responded to social changes and vicissitudes. Hence, this Essay sets out to do a number of things. First, this study succinctly examines the nature and status of law in North Korea. Second, it reviews the country\u27s constitutional history in sequence, and then, provides a more in depth look into the characteristics of the current Constitution. Conclusions are then drawn from this examination. The goal of this Essay is not to describe the principles or contents of North Korean Constitutions per se, but rather to look at how North Korea has responded to change from a constitutional perspective. However, our discussion will be mostly limited to the texts of the constitutions since there is no case known to outsiders that would afford us an understanding of its real operation in daily life. At the same time, constitutional processes including the North Korean amendment process does not deserve our attention either, as all constitutional processes in North Korea are, by design, endorsed without opposition and manipulated by the country\u27s top leadership --an undisputable reality of the totalitarianism housed within the country\u27s borders

Analysis of truck delays at container terminal security inspection stations

After September 11, 2001, special attention has been given to the vulnerability at container transportation to terrorist activities. United States Customs and Border Protection (CBP) has set up inspection stations for containers at seaport terminals to screen containers, but this practice affects the truck turnaround time in the seaport by generating additional processing delays. This dissertation analyses the additional truck turnaround time incurred at the inspection stations under various levels of security. Queuing models were used to estimate truck delay as containers are inspected at two successive security inspection stages. Each stage may utilize one or more inspection equipment. The objective is to determine the number of equipment needed to keep the total delay at an acceptable level. Homeland security, CBP, seaport terminal officers, truck and marine carriers may use this research to develop an effective and efficient plan for handling marine freight and containers

New Developments in Korean Constitutionalism: Changes and Prospects

This Essay examines constitutionalism, or the legal expression of democracy. Explanations of Korea\u27s underdeveloped sense of constitutionalism which are rooted in the culture of Confucianism do not provide an adequate explanation of the post-1948 Korean experience. A better model is provided by contrasting the uses of law by prior authoritarian regimes with current political developments including the rising role of entrepreneurial interests in Korean politics

Some Surfaces with Zero Curvature in ℍ

We study surfaces defined as graph of the function z=f(x,y) in the product space ℍ2×ℝ. In particular, we completely classify flat or minimal surfaces given by f(x,y)=u(x)+v(y), where u(x) and v(y) are smooth functions

dissertationMarine electromagnetic (EM) surveys have been extensively used for offshore hydrocarbon exploration over the last decade. One can consider two major types of marine EM surveys. One is aimed at conducting a reconnaissance study of the large survey area with the purpose of locating the prospective zones of hydrocarbons accumulation. Another type of the EM surveys is used for a detailed study of these prospective zones with the goal to determine a specific position of the potential HC reservoirs. In this dissertation, I introduce two new techniques for solving these two important problems â€" optimal synthetic aperture method for analysis of the reconnaissance surveys and a hybrid finite difference and integral equation method for rigorous 3D inversion of the EM data collected by exploration surveys. The optimal synthetic aperture method is a technique to find the optimal parameters of the synthetic aperture of the EM data acquisition system, which can steer the generated EM field toward the area of interest by combining the responses from multiple sources, so that it can enhance the anomaly from the potential HC target. With the application of the optimal synthetic aperture method to the conventional MCSEM data and the towed streamer EM data, I demonstrate that the method can be used for not only increasing the EM anomaly from the target, but also reducing the distorting airwave effect in the shallow marine environment. I also demonstrate that the method can be used for mapping the electric anomalies over the true locations of the targets, which is important for the reconnaissance surveys. The second technique that I have developed is the hybrid finite-difference and integral equation (FD-IE) method for 3D modeling and inversion of the EM data, which combines the advantages of conventional FD and IE methods. The hybrid FD-IE method makes it possible to provide a more accurate and efficient forward modeling solution than the conventional FD or IE methods for multisource data. The developed new approaches to analysis and interpretation of the marine EM data have been carefully tested on a number of realistic synthetic models and a case study

Surfaces of revolution in the three dimensional pseudo-Galilean space

In the present paper, we study surfaces of revolution in the three dimensional pseudo-Galilean space G31 . Also, we characterize surfaces of revolution in G31 in terms of the position vector field and Gauss map
