Hundreds of thousands of South Korean protesters staged candlelight vigils and demonstrations against US beef imports in 2008. The problems, however, went far beyond that of beef imports. The political party veterans, who lost the presidential election, exploited labor unions that were discontent with the economy and ideological student groups to weaken the majority party. In this study, an epidemiological model is constructed with a system of three nonlinear differential equations. The model seeks to examine the dynamics of the system through stability analysis. Two threshold conditions that spread the protests are identified and a sensitivity analysis on the conditions is performed to isolate the parameters to which the system is most responsive. The results are also explored by deterministic simulations. This model can be easily modified to apply to other protests that may occur in various circumstances.

The purpose of this paper is to present some main economic factors which influence Gaza Seaport. Without direct access to the international market, the Palestinian economy will continue its dependence on Israeli economy mainly in employment, transport facilitation, and international trade. The greatest potential for Palestinian economic growth lies in trade. The port is important for creating new job opportunities, and for enhancing exporting capabilities, which are the most essential elements for development of the Palestinian economy. Israeli policies and procedures incur Palestinian exporters additional transportation costs when delivering their products to Israeli Ports or when transit these products to neighboring countries through Israeli controlled area. The public profit for the port is greater than the private profit. Therefore, constructing the port will have a great effect on the Palestinian economy. There are many challenges facing the port, some of them are the political stability, the economies of scale, and Israeli security measures and procedures.

The purpose of this study is to evaluate the residential environment by indicators of internal and external conditions of Purchased Rental Housings (PRH). In this study, we conducted a field survey on 200 units of PRH to evaluate the residental environment located in Seoul, Incehon, Kyounggi, Daejeon, Busan and Daegu. As a result, the residential environment of PRH is managed as above average at most indicators. Partly parking areas and fire-fighting facilities are need to be improved for safety and health. It is considered that the political goal of PRH, such as housing safety and stability for low-income class, is achieved by decent housings and appropriate maintenance. However, it is still necessary to improve its management system for sustainable and safe residential environments.

The purpose of this study is to examine empirically the short- and long-run determinants of entrepreneurial activity in a sample of 15 the Middle East and North African economies between 2006 and 2018. More specifically, four groups of determinants are considered in the analysis, namely economic, demographic, business environment, and institutional. Given the autoregressive feature of the entrepreneurial activity process, a dynamic panel data model is estimated using the system GMM estimator. Findings reveal that unemployment, trade openness, population density, and economic freedom are the main drivers of new business creation in the short-run, while the cost and number of procedures to start a new business negatively affect entrepreneurship. In the long-run, the same findings hold true. Moreover, education and political stability and the absence of violence/terrorism positively affect entrepreneurial activity. Policy recommendations are accordingly designed.

This study on Mahāsammata Model of Kingship in Mrauk U Period from the 15^th to 18^th centuries attempts to demonstrate how the kings of Mrauk U or royal officials tried to claim this legitimating model of kingship and how they accepted this model of kingship and under what conditions the legitimate order of this model was lost. Vital to the adaptation of Mahāsammata model of kingship in the Mrauk U period is the claim that Mrauk U's rulers were direct lineal descendants of the first Buddhist king of the world, Mahāsammata and thence the clan of Gotama Buddha, Sākiya clan. This ideological model of kingship has a recognizable effect on the political stability of Mrauk U kingdom. While the Mahāsammata model of kingship performed as a belief of legitimizing kingship within the arena of royal court, the kings of Mrauk U tried to perform the related models of Mahāsammata, the ideal models of Buddhist kingship as dhammarāja and a cakkavatti. However, the conditions that fail to maintain the Mahāsammata model of kingship saw the weakening of the other related models of kingship, which eventually led to the decline of the kingdom.

This paper aims to emphasize the necessity of beginning and developing judicial politics in Korea. Law is constitutive of politics, and judicial politics is vital in understanding how politics is influenced by law. Disappointingly, social science in Korea has not recognized the importance of judicial politics. Judicial branch in Korea does not have the capacity to constrain the executive or other government agencies governed by elected officials. The rule of law does not work. Judicial politics has not yet been introduced in Korea, despite its enormous importance in shaping political economy. The rule of law and courts are believed to be the institutional foundation for economic growth. Law embodied in "no one is above the law" is recognized to provide fairness and stability with a democracy. Little attention to judicial politics results in leaving behind a missing link in a polity. The fortification of the rule of law is necessary to make democracy consolidated in Korea, as shown in impeachment of former president Park Geunhae. A new scholarship in Korea on judicial politics is in need to discuss what conditions under which the rule of law is possible and how to make it sustainable.

The conflict between Iran and Israel has been a major source of instability and security threats in the Middle East. This study analyzes the historical background and modern aspects of the Israel-Iran conflict, examining its root causes, nuclear issues, proxy wars, cyber warfare, economic sanctions, and the role of the United States. The research employs qualitative methods, including literature review and case analysis, using various sources such as academic papers, government reports, and media articles. The findings suggest that the conflict is deeply rooted in historical, religious, and political factors, and has escalated since the 1979 Iranian Revolution. The study highlights the need for dialogue, negotiation, and international mediation to resolve the conflict and maintain regional stability. The Israel-Iran conflict also provides valuable lessons for addressing the North Korean nuclear issue, emphasizing the importance of dialogue, international cooperation, and confidence-building measures.

Painting, as an artistic creation with aesthetic characteristics, is inseparable from "shape". "Modeling" is a subjective way of expressing objects, and "black shape" is not only a way of expression, but also a way of composition. "Black shape" is a way of expressing the overall picture of the creator, and "black shape" extracted from the pattern analysis of black and white gray structure is a powerful means to deeply explore the emotions and thoughts of the painter. How to create the expression of subjective intention in the creation of artificial figure painting and to explore the beauty of picture form and the presentation of formal language in multiple dimensions is always sought by painters. Tang Dynasty political stability, economic and cultural development of unprecedented prosperity, "Toujian Diu" as a representative painting of Tang Dynasty, the figure is plump and realistic, colorful but elegant. It not only represents the aesthetic taste of the Tang Dynasty, but also reflects the overall style of the Tang Dynasty's artificial figure painting. The aim of this paper is to explore the value of "black shape" in "Toughen Diagram" and analyze its multi-component form in depth.

Tunnels have been an integral part of human civilization. Due to complexity in its design and structure, the stability of underground structures under extreme loading conditions has utmost importance. Increased terrorism and geo-political conflicts have forced the engineers and researchers to study the response of underground structures, especially tunnels under blast loading. The present study has been carried out to seek the response of tunnel structures under blast load using the finite element technique. The tunnel has been considered in quartzite rock of northern India. The Mohr-Coulomb constitutive model has been adopted for the elastoplastic behaviour of rock. The rock model surrounding the tunnel has dimensions of 30 m x 30 m x 35 m. Both unlined and lined (concrete) tunnel has been studied. Concrete Damage Plasticity model has been considered for the concrete lining. Four different parameters (i.e., tunnel diameter, liners thickness, overburden depth and mass of explosive) have been varied to observe the behaviour under different condition. To carry out blast analysis, Coupled-Eulerian-Lagrangian (CEL) modelling has been adopted for modelling of TNT (Trinitrotoluene) and enclosed air. JWL (Jones-Wilkins-Lee) model has been considered for TNT explosive modelling. The paper concludes that deformations in lined tunnels follow a logarithmic pattern while in unlined tunnels an exponential pattern has been observed. The stability of the tunnel has increased with an increase in overburden depth in both lined and unlined tunnels. Furthermore, the tunnel lining thickness also has a significant effect on the stability of the tunnel, but in smaller diameter tunnel, the increase in tunnel lining thickness has not much significance. The deformations in the rock tunnel have been decreased with an increase in the diameter of the tunnel.

Department of the imperial guard is of the soldiers organization which is formed in the royal power or the absolute near by a king. Thus, department of the imperial guard absolutely is showed it is a soldiers organization for guard a king. We summary the character and the function as followed when we subdivide. 1. The main mission was the guard of the royal palace. As we know from several historical materials, the defense of the royal palace was an fundamental mission. Therefore, department of the imperial guard would take charge of the defense of the royal palace. 2. They would carry out throne of king and the royal family or a battle. As unification, they would carry out guarding for political stability and a suppress probation of internal war in regard to the security and the frequent rebellion in central and locality. 3. They carried out guarding an honored going of a king or the royal family. We know the fact that there was an honored going of the royal family or many attendants on record. When a king or the royal family go, guarding of department of the imperial guard had not only protect them but also show off the authority of the royal family. As a result, when we analysis the substance from studying the guard system of Shilla, though our guard system is imitated the foreign guard system like U.S.A, transcending space-time, the guard system can be found a lot of something common at the guard principle and a rule. Today, in looking about a political system of any countries on the world, a king and a ruler of the country represent their country international, have responsibility of protect their nation and a people internal. Therefore, the guard for a ruler absolutely must carry out at a safety situation. Moreover the guard organ, at the same time is connected directly to a welfare of the nation, so we will have to devote a constant effort.
