Almost all of the nations run a game screening system which is characteristic depending on their communication policy. This article attempted comparative analysis about major nation's game screening systems by comparing three main aspects of their communication policy which are freedom of expression, complete opening of the contents to the public, and the balance between protection of adolescent and promotion of industry. It is shown that the screening system of USA, Europe and Japan stick well by the basic principles of communication policy, on the other hand Korea, South Africa Republic and Australia have some points that need improvement.

Recently people show interest in cultural exhibition space targeting on children from the birth of children to play and education. Accordingly, lately the necessity of professional special exhibition space, which is composed of changeable program fit to the children trend of a growth period, and shows relatively more freedom and adaptability in directing the theme than permanent exhibition, have increased rapidly. Today the social importance of special exhibition for children is emphasized as an alternative that can provide efficiently the expression of freedom and the environment of experimental space which is not filled in existing academy or school. The necessity of special exhibition space for children is raising to the climax at this moment, this study has the meaning to analyze the direction of domestic special exhibition for children progressed in last 1 year, and then to suggest basic guide and direction for future plan of special exhibitions.

In this study, we will analyze the artistic character of Jogakbo as a element of fashion art design. Korean traditional Jogakbo is a common homemade item made from clothing remnants and is a part of the culture of women�s quarters. Currently, Jogakbo is higly regarded for its artistic value and it finds a variety of uses in fashion. In particular, it is striking how its modern-style geometric lines and color composition are congruous with abstract art. In applying Jogakbo to fashion art design, we study the artistic expression of Jogakbo in 4 aspects; namely, line, color, material, and technique; and analyze the 4 artistic characteristics; beauty of naivety, simplicity, moderation and freedom. 8 dresses designed based on these 4 characteristics are presented as examples.

Three dimensional cutting is considered as an equivalent orthogonal cutting through the plane containing both the cutting velocity vector and the chip flow velocity vector in dynamic cutting process. An analytical expression of dynamic cutting force is obtained from the cutting parameters determined by the static cutting. Particular attention is paid to the energy supplied to the vibratory system of cutting tool with two degree of freedom. In this approach, the phase lag of the horizontal vibration of the tool behind the vertical vibration and the direction angle of the fluctuating cutting force is considered in point of stability limits. Chatter vibration can be effectively suppressed by relatively increasing the spring constant and the damping coefficient of the cutting system in the vertical cutting force direction. A good agreement is found between the stability limits predicted by theoretical value and experimental results.

A program is developed for generations the dynamic equations for robotic manipulators using the symbolic language muSIMP/MATH. The muSIMP/MATH is a LISP-based computer algebra package, devoted to the manipulation of algebraic expressions including number, variables, functions, and matrix. The muSIMP/MATH can operate on IBM-PC compatibles with MS-DOS. The program is developed, on the e formalism. This is program is applicable to the manipulators of any number of degrees of freedom, maximum six degree of freedom in this program. To control robotic manipulators by using dynamic equation is required a symbolic equations. The generated dynamic equation can be applied directly to the robotic manipulators, for the generated dynamic equation is a reduced form of symbolic expression.

The laws and policies governing Korea's game regulations are becoming more and more topics for debate as we enter the Age of Internet. The nature of the basis for Internet regulations and policies are not rooted in freedom of speech or fundamental values of democracy, but rather focused on solving real-world problems such as protection of the youth. Furthermore, the reality is that regulatory devices for keeping the social order such as regulating gambling are being applied directly to games without consideration on the characteristics of Internet gaming, raising concerns that the expansion of constitutional values and innovative empowerment inherent to the Internet are being weakened. The Geun-Hye Park Administration which succeeded Myung-Bak Lee's Administration, even went so far as to implement the so-called "Shutdown Policy", which prohibits access to Internet games during pre-defined time zones and also instigated a time zone selection rule. In order to curb the gambling nature of Internet games, government-led policies such as the mandatory personal identification and prohibition of player selection or in other words mandatory random player selection are being implemented. These institutions can inhibit freedom of speech, which is the basis of democracy, violate the right of equality through unreasonable discrimination between domestic and foreign service providers, and infringe upon the principles of administrative law, such as laws, due process in policies, and balance in among policies and governmental bodies. Going forward, if Korea's Internet game regulations and polices is to develop in a rational manner, regulatory frameworks will need to be designed to protect the nature of the Internet and its innovative values that enable the realization of constitutional values; for example, the Internet acting as the "catalytic media for freedom of expression as a fundamental human right ", which has already been acknowledged by the Korea's Constitutional Court. At the same time, transparent procedures should be put into place that will allow diverse participation of stakeholders including game service providers, game users, the youth and parents in the legislation and enforcement process of regulatory institutions; policies will also need to be transformed to enable not only regulatory laws but also self-regulation system to be established. And in this process, scientific and empirical analysis on the expected effects before introducing regulations and the results of enforcing regulations after being introduced will need to be strengthened.

This paper deals with the legal meaning and issues of street performances. The key elements in the legal sense of street performances (or artistic performances) are 'public places' and 'artistic activities'. Therefore, as far as belongs to "artistic activities in public places", we can call them in principle as street performances regardless of its level of art, whether they are paid or not, size of performances or genre of artistic activities. Street performances are a way for anyone to freely participate and enjoy art by being performed on open places. In addition, street performances can be seen as more popular and democratic artistic acts than mainstream art culture in that anyone can become street performers. Although street performances are in vogue and becoming a universal cultural phenomenon, they do not appear to be legally organized yet. However, we don't have to strictly regulate street performances on the grounds that they are something different and special. Instead, they should let their street performances be freely performed and enjoyed in accordance with the constitutional law that guarantees the freedom of art or the freedom of artistic expression. Of course, it is necessary to modify the relevant laws on key issues raised regarding street performances. Finally, for street performances to be well established as cultural phenomenon, it should be harmonized that efforts to observe the law and orders by street performers, mature rituals and cultural tolerances of citizens who enjoy street performances, and efforts to realize the purpose of cultural countries and to promote street performances by governments.

This study began by pointing out the problem of domestic media reporting on 'fake news' regulations that frequently appear through the French 'Les proposals de loi control de l'information'case, while still approaching with different standards and perspectives on where to see fake news. In the age of 'social network services', the answer to what the media is, what the news is, and who the reporter is increasingly difficult. While reviewing the long history and background of the spread of fake news examined in this study, it was confirmed that could not determine the concept and scope of fake news, punished, regulated, controlled, or judged simply by one standard. From the perspective of 'freedom of expression' set by the law, we have the authority to express our opinions freely. In addition, 'online' space is a place where fake news is generated and spread, but at the same time, there is plenty of room to act as an antidote. In the end, the only alternative to the damage of long-term fake news will be to create a media environment that allows more high-quality "real news" to pour out, allowing us to develop our ability to judge reliable information through balanced competition among various news in the free market of ideas.

A class of new observers in descriptor linear systems, proportional-derivative(PD) observers, are proposed. A parametric design approach for such observers is proposed based on a complete parametric solution to the generalized Sylvester matrix equation. The approach provides complete parameterizations for all the observer gains, gives the parametric expression for the corresponding left eigenvector matrix of the observer system matrix, realizes elimination of impulsive behaviors, and guarantees the regularity of the observer system.

This paper is a comparative analysis of constitutional decisions in which the Korea Consitutional Court and the United States Supreme Court applied the void for vagueness doctrine into free expression issues. Common aspects are: both courts applied the void for vagueness doctrine on the grounds that vague laws bring chilling effect on freedom of expression. Acknowledging inevitable uncertainties in lawmaking and legal jargons, however, both courts required minimum standards in the void for vagueness doctrine. In the cases where unclear legal meanings resulted in constitutional challenges, both courts adopted the "narrowing construction" by the courts or judges based on average/ordinary person's understanding. The biggest differences between the two constitutional courts are their approach to the degrees of vagueness allowed in free expression cases. The U.S. Supreme Court underscored the necessity of narrowly drawn, reasonable and definite standards. Meanwhile, the Korea Constitutional Court relaxed its standards in some cases such as the National Security Law cases, even though it admitted the possibility of curtailing the right to free expression. The Court reasoned that those laws, though vague, brought with bigger social interests and are necessary tools in dealing with changing world.
