In this paper, we show that various navigation constant values in PNG law can result in as optimal gains when we introduce proper time-varying weighting functions into the cost function of an optimal control problem. we then apply this idea to the guidance problem where we are required to achieve a given impact angle as well as the zero miss distance. As a result, we obtain a set of optimal guidance laws each of which could be related to a navigation constant in PNG. Some basic properties of these guidance laws are also presented.

While past traffic laws have focused on solving problems related to traffic congestion, the current legislation must play a role in reducing the social cost of solving traffic problems by forecasting future issues based on current traffic situations, setting goals in advance, and leading the traffic modal choice-trend. This paper verifies that the bimodal tram should be an alternative means of public transportation and proposes ways to introduce and promote it based on a government subsidy and the modification of traffic laws.

The objective of this study was to investigate the experience and perception of sexual violence based on the right to women's body. For empirical analysis the data on 376 female students and 320 male students on two universities were collected. The major findings were as follows; Most of male students usually did sexual violence to women and lots of female students easily were invaded her right to body. The range of conception which the students perceived as sexual violence was wider than that of related laws Thus in order to secure sexual equity this study proposed that laws should reflect widely the right to women's body and that male students should be educated to respect it.

This study is to explore the development of Korean National Emergency Management System. For the study's purpose, the concept of Emergency, Emergency Management and the existing system and related laws of National Emergency Management have been reviewed. In South Korea, the concept of National Emergency Management contains the variety concept of emergency management; safety management, security management, risk management and disaster management etc. and sometimes using them interchangeably. In addition, there are several laws related to emergency management, making different agencies managing inter-related emergency without nationalized coordination and control tower that results in ineffective management of national emergency. This study attempts to clarify the concept of national emergency and to suggest the necessity of National Integrated Emergency Management System(IEMS). Then, it suggests existing system and related laws's integrate for the development of South Korean National Emergency Management System.

The purpose of this study is systematically to examine the changes that have taken place to the community spaces of apartment complexes in the national capital region of Korea. The methodology used in this study entails analyzing existing research and case studies carried out on this subject matter. Prior to these case studies, an existing study had been made of the chronological changes in policy, related laws and regulations in Korea since the 1960s. This case study presents the component ratio and systematized present situation of community spaces in twenty-two apartment complexes. An analysis of the researching process has revealed the following important factors related to the changes that have occurred in community spaces in apartment complexes. (1) Apartment complexes were originally developed in the 1960s to ease the housing shortage. Because the priority was to solve the housing shortage, community spaces were not widely considered or developed. (2) The standard of community spaces was established as mandatory by law in the 1970s, resulting in the emergence of various facilities that provided community spaces. (3) In the 1980s, various design competitions for apartment complexes were conducted as an attempt to improve residential environments. This process resulted in the development of new characteristic of subsidiary facilities. (4) During the period when housing problems were being addressed in the 1990s, the Community Service Center was added to the welfare facilities for residents. (5) Recently, during the 2000s, an improvement in residential environments has evolved due to the expansion of housing supply and economic growth. The quality of community spaces has therefore improved from the 1960s onward. This study revealed that policy and related laws regarding community space in Korea have been developing in a suitable direction and that the addition of various facilities to community spaces has improved the quality of living environments.

Libraries and information centers are no different from any other institutions in our society. Today, their managers have to make many more decisions which have certain legal implications than before. The ignorance of the law on their parts can not be an acceptable excuse anymore, since. the consequences sometimes maybe quite serious. This paper outlines some important legal issues involved in the services and management of libraries and information centers. They are: constitutional rights on human knowledge activities: library act and it's related laws; censorship and right to know; information access and the protection of privacy: library services and copyright law; labor relations; protections of the people and properties of the institutions, etc. The laws are not static: rather, they change with the social, political and technological environments. The managers, as well as the staff members of libraries and information centers should be constantly updated with the changes in the field, in order to give the maximum service to the clients and to prevent any infringement of the laws, which may discredit their services and the institutions.

The "Technical Regulations on the Telecommunication Facilities". under the provision of the "Telecommunication Basic Law", has rather complicated mechanism in its implementation because of wide relationship with various laws. This paper studies the principle of technical regulation and configuration with related laws, and then gives a suggestion on the future improvement of the regulation.t of the regulation.

The concrete stiffness matrices of membrane elements used in the finite element analysis of wall-type structures are reviewed and discussed. The behavior of cracked reinforced concrete membrane elements is first described by summarizing the constitutive laws of concrete and steel established for the two softened truss models (the rotating-angle softened-truss model and the fixed-angle softened-truss model). These constitutive laws are then related to the concrete stiffness matrices of the two existing cracking models (the rotating-crack model and the fixed-crack model). In view of the weakness in the existing models, a general model of the matrix is proposed. This general matrix includes two Poisson ratios which are not clearly understood at present. It is proposed that all five material properties in the general matrix should be established by new biaxial tests of panels using proportional loading and strain-control procedures.

With the commercialization of CDMA 2000-1x late in 2000, a high-speed wireless Internet, based on a mobile communication networks, appeared in Korea. This will develop into the next-generation of mobile communications(4G) in the future and the new cell layout will be required the cellular configuration of 4G. We would need the legislation with respect to base-stations and to building the mobile communication networks, as well as the optimization of mobile communication systems. In this study, in order to provide 4G, I examined and analyzed that the current laws & regulations related to licensing and operating a mobile communication base-stations in KOREA.
