The objective of this study is to generally check the present situation of private security industry by analyzing the current situation of private security industry in Korea so as to find which policy base is reflected to amend law by analyzing the amendment process of private security law in order to suggest policy direction of private security industry in Korea. Viewing through amendment process of private security law, enhancing publicity and enterprise are not judged to form any definite policy base. They are merely interpreted to partially reflect enterprise under the strong base of publicity. Such policy base may cause overall stagnation of private security industry. For sound development of private security industry, it is required to get out of the existing policy direction so as to change policy base to the direction of enhancing enterprise of private security industry. The power of police for instruction and supervision should be largely transferred to Korea Security Association so as to cultivate autonomous purifying function of private security industry. Police should strive to develop policy in the level of joint production of security service.

Large metropolitan areas in the US are distinguished by highly fragmented fiscally independent suburban municipalities and special districts. The suburban fragmentation implies the congregation of similar socio-economic groups escaped from central cities and the disparity of geographical resources among local government jurisdictions. This study examines St.Louis County suburbs as a case study for the implictions of suburban governmental fragmentation and the fiscal disparities across local governmental boundaries by analyzing their relationship with public service provision using police and public school services as examples. The distribution of fiscal resources across political boundaries, the processes which created them, and public service inequalities reproduced from the disparity of fiscal resources reveal the causes and consequences of suburban governmental fragmentation. The central part of suburban fragmentation is the segregation of public goods consumption reproduced from the disparity of local fiscal resources, and it acts as a basic geographical segregating force in the suburban spatial organization.

The International Association Marine Aids to Navigation and Lighthouse Authorities (IALA) proposed guidelines for VTS manual operation in 2016 for safe and efficient operation of ship. The Korea Coast Guard (KCG) established and operated 19 VTS centers in ports and coastal waters across the country by 2022 based on the IALA VTS manual and VTS operator's education and training guidelines. In addition, IALA proposed the Inter-VTS Exchange Format (IVEF) Service recommendation (V-145), a standard for data exchange between VTS, in 2011 for efficient e-Navigation system services and safe and efficient VTS service support by VTS authorities. The IVEF service in a common framework for ship information exchange, and it presents seven basic IVEF service (BISs) models. VTS service providers can provide safer and more efficient VTS services by sharing VTS information on joint area using IVEF standards. Based on the BIS data, interaction, and interfacing models, this paper introduced the development of the cloud-based VTS integration services performed by the KCG and the results of the VTS integration platform test-bed for IVEF service implementation. In addition, the results of establishing a cloud VTS integrated platform test-bed for the implementation of IVEF service and implementing the main functions of IVEF service were presented.

Like to change to the information-oriented society, the guard service needs to be changed. The communication and hardware technology develop rapidly and according to the internet environment change from cable to wireless, modern person can approach every kinds of information service using wireless communication machinery which can be moved such as laptop, computer, PDA, mobile phone and so on, LBS field which presents the needing information and service at anytime, anywhere, and which kinds of device expands it's territory all the more together with the appearance of ubiquitous concept. LBS use the chip in the mobile phone and make to confirm the position of the joining member anytime within several tens centimeters to hundreds meters. LBS can be divided by the service method which use mobile communication base station and apply satellite. Also each service type can be divided by location chase service, public safe service, location based information service and so on, and it is the part which will plan with guard service development. It will be prospected 8.460 hundred million in 2005 years and 16.561 hundred million in 2007 years scale of market. Like this situation, it can be guessed that the guard service has to change rapidly according to the LBS application. Study method chooses documentary review basically, and at first theory method mainly uses the second documentary examination which depends on learned journal and independent volume which published in the inside and the outside of the country, internet searching, other kinds of all study report, statute book, thesis which published at public order research institute of the Regional Police Headquarter, police operation data, data which related with statute, documents and statistical data which depend on private guard company and so on. So the purpose of the study gropes in accordance with the LBS application, and present the problems and improvement method to analyze indirect of manager side of operate guard adaptation service of LBS, government side which has to activate LBS, systematical, operation management, manpower management and education training which related with guard course side which has to study and educate in accordance with application of the new guard service, as well as intents to excellent quality service of guard.

This paper proposes that we need a simpler method for developing the Website strategy for public institutions. The research objectives are threefold: (1) A model that relates to the monitoring of Website strategy in the public sector is proposed. The model includes basic dimensions and a $2{\times}3$ matrix that is a simplified version of the Mohammed et dl.s Marketspace Matrix. (2) The model is tested empirically with a sample of 56 Websites selected from govemment agencies, military organizations and police stations in Korea. (3) The effect of dimension/factors on the innovation level is tested. A special attention is paid to online attracting that is important for public institutions which usually do not use offline advertising aggressively. Results from regression analyses show that main dimensions (Marketing Drivers and relationship Stages) and three factors (Basic Information, Support Information, and Participation) in the matrix are all significantly influential on the innovation level, but the Attracting is not. Colorful designs and attracting features of a homepage have not necessarily anything to do with innovation. This message can offer a good piece of advice for managers of Websites.
