In Korea, cable television(CATV) broadcasting has begun in March, 1995. This Paper aims at examining the location of CATV broadcasting station, and demand density(numbers of viewer houshold) of broadcasting area, and at clarifing the factors affecting subscription. The results are as follows: The number of CATV stations is 54 in 1996, and these CATV stations are mainly located in larger cities. The correlation between the number of established or planned CATV station and the number of household is very high. In sphered broadcasting area Permitted in 1997, the location of CATV station is about 73,000 household and 230,000 persons in the minimum values of household and population, and diameter of sphered broadcasting area is 40.6 km in mean. The factors affecting subscription rates of CATV are median age and supply rates of apartment of each dong in Chongju city and each myun in Chongwon county. The correlation between subscription rates of CATV and supply rates of apartment appears higher than correlation between subscription rates and median age other factors based on residual analysis of regression equation are established period of transmission network of CATV and acceptance attitude of dwellers.

Construction of Private networks is becoming easier due to the openness of telecommunication market, rapidly developing telecommunication technology. The size of existing private networks is becoming huge which resulted in surplus of capacity of the networks. These trends will generate a problem of efficient use of national telecommunication resources and which will be a factor for the structure of domestic telecommunication market which will have a big impact on the existing telecommunication carriers. Therefore, national policy of private network issues should be considered along with the national efforts for the information infrastructure, control of telecommunication market, fairness of competition, strength Power of national competition. In this paper it will be suggested that the efficient policy on the issue of domestic private network, by analyzing present situation, status quo, laws, regulation and procedure for domestic private networks and comparing it with those of U.S.A, Japan, EU.

Korean port developments have been mostly made by the central government. With the introduction of the Port Authority system, however, roles and function assignments of the central government in port development have been in change and the Port Authority has to find a solution for inducement of private investment in port development. This paper has examined the current legal system of port developments and then sought the way for inducement of private capital to improve specialty and efficiency of harbor facilities management and development under Port Authority. As the Ministry of Maritime Affairs and fisheries(MMAF) has two types of legal system for inducement of private investment on port developments, the Port Authorities can also have two types of private finance. Private finances by the Port Authorities has some more critical advantages than the one by the central government. It is also required to change the the administrative permissions and concession agreements which MMAF conveyed to private participants in port developments into the concession agreements between Port Authorities and private participants.

The in vitro effects of trisodium phosphate and cetylpyridinium chloride on E. coli 0157:H7 and L. monocytogenes were investigated. The trisodium phosphate and cetylpyridinium chloride was bactericidal toward E. coli 0157:H7 and L. monocytogenes. The killing effects of the $1{\times}10^{-2}\;M$ trisodium phosphate on E. coli 0157:H7 and L. monocytogenes were 30~40%, 40~50%, respectively. The killing effects of the $5{\times}10^{-7}\;M$ cetylpyridinium chloride on E. coli 0157:H7 and L. monocytogenes were 90~95%, 95~99%, respectively. The killing effects of the trisodium phosphate was $10^5$ times that of the cetylpyridinium chloride. Factors effecting the bactericidal action of trisodium phosphate and cetylpyridinium chloride were investigated and the action depended on temperature and pH.

Nowadays NGN is developed for supporting the e-Commerce, Internet trading, e-Government, e-mail, virtual-life and multimedia. Internet gives us the benefit of remote access to the information but causes the attacks that can break server and modify information. Since 2000 Nimda, Code Red Virus and DSoS attacks are spreaded in Internet. This attack programs make tremendous traffic packets on the Internet. In this paper, we designed and developed the Bandwidth Controller in the gateway systems against the bandwidth saturation attacks. This Bandwidth con-troller is implemented in hardware chipset(FPGA) Virtex II Pro which is produced by Xilinx and acts as a policing function. We reference the TBF(Token Bucket Filter) in Linux Kernel 2.4 and implemented this function in HDL(Hardware Description Language) Verilog. This HDL code is synthesized in hardware chipset and performs the gigabit traffic in real time. This policing function can throttle the traffic at the rate of band width controlling policy in bps speed.

Recently, the design and supervision separating system has have been widely adopted in Korea. In this system, the owner should exclude the architect who designed the building from supervisor in the same project. The design and supervision separating system has advantage of less fraudulent construction and weakness of design intention reflection difficulty in construction stage. In this study, the status, problems and solutions of this system are identified from expert survey and interview. The main results of this study are as follows. First, the work scope of designer and supervisor should be clear and the guidelines for this system should be clearly defined. Second, the optimal price for the work scope should be guaranteed. Also, the education program for the improvement of supervisor capability should be provided.

The integrated environmental permit system is currently in operation online. It carries out various functions of postmanagement such as the submission of annual reports containing operations management data onto integrated management workplaces, the operation and management of emission facilities and prevention facilities, and the disclosure of information on the integrated permission. On the other hand, the integrated environmental permit system needs to perform various roles in order to stably manage and smoothly perform the permitting work. It is necessary to utilize this system to establish policies by using diverse operations management data onto integrated management workplaces collected in the integrated environmental permit system. This system can also play a role in improving the post-management system and user convenience after the permission review and approval processes. The integrated environmental permit system can be effectively used to set up the BAT-AEL because it collects all of the cross-media data and identifies the overall status of the workplace. In order to establish a post management system after the approval, it is necessary to provide performance management and performance evaluation functions as conditions of the permit after approval. In addition, a variety of support functions should be provided to enable the permission authority and the environmental expert examination agency to facilitate the review of permits. It will be necessary to provide an evaluation system and a proactive diagnostic function to determine whether permission conditions and permit emission standards will change in the future. Also, it is important to adopt an information exchange platform that can be used to collect the status data onto the workplaces; the platform can also be used as an information exchange site for technical working groups (TWG), and for collecting field experts' opinions.

The government is propelling regulatory reform in priority that abrogate & improve administrative regulation. But in spite of many regulatory reform results, successive diminution of regulatory reform is low because that modification of bureaucracy's execution don't support or a concerned group of gain and loss resists. Therefore, this study grasp the present condition at dangerous article factory etc., and would present the promotable method in analysis synthetically & systematically about cognizance, recognition & observance etc of a administrative regulation. As a result of inquiry, In general the adaptability is evaluated highly. This is a natural result because of rapidly economic development, increased demand of a dangerous article and so an increase of riskiness, and showed that the general public recognize riskiness of dangerous article factory etc..
