Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

Various methods have been developed to predict the flight path of an air-launched weapon to intercept a fast-moving target in the air. However, it is also getting more challenging to predict the optimal firing zone and provide it to a pilot in real-time during engagements for advanced weapons having new complicated guidance and thrust control. In this study, a method is proposed to develop an optimized weapon engagement zone by the SCG (Scaled Conjugate Gradient) algorithm to achieve both accurate and fast estimates and provide an optimized launch display to a pilot during combat engagement. SCG algorithm is fully automated, includes no critical user-dependent parameters, and avoids an exhaustive search used repeatedly to determine the appropriate stage and size of machine learning. Compared with real data, this study showed that the development of a machine learning-based weapon aiming algorithm can provide proper output for optimum weapon launch zones that can be used for operational fighters. This study also established a process to develop one of the critical aircraft-weapon integration software, which can be commonly used for aircraft integration of air-launched weapons.

The aim of this study is to conduct a comparative study on the sustainability of the public pension. While the mainstream view on the sustainability of the public pension presupposes financial sustainability, the original purpose of guaranteeing retirement income has been overlooked. The sustainability of the public pension needs to consider not only financial sustainability, but also various factors such as demographic structure, labor productivity, industrial structure, life cycle of working households, government spending on public pensions, economic growth, and social consensus. With this awareness of the problem, this study conducted a fuzzy set qualitative comparative study in 44 countries, including Korea. As a result of the analysis, it was found that Korea had high financial sustainability for a single year, but relatively low integration related to social consultation and public pension operation, and adequacy such as the degree of guarantee and linkage with other pension systems was also relatively low. The sustainability of the broader public pension should be emphasized not only for financial sustainability, but also for adequacy and integration.

M&A is an important strategic decision made to ensure the competitiveness of companies and cases of M&A have been increasing in recent years. But the success of an M&A is not assured. In order to succeed, there should first be a well managed strategic leadership by the CEO and an integration strategy. Companies need also to overcome the resistance to change among members. A successful example of an M&A is that of LG Chem and Hyundai Petrochemical. By using this M&A as a case study, the influence of the CEO's Strategic Leadership, and the Integration Strategy on Resistance, Acceptance and Performance were assessed. For this study, research was conducted on CEO Strategic Leadership and Integration Strategy before members of LG Chem (DAESAN PLANT) were interviewed on the M&A's implementation by LG Chem's HR staff, management and members. The results show that CEO strategic leadership and the integration strategy are major change drivers and that they are important to the early stabilization of M&A companies. Finally, suggestions are made as to how such success may be replicated for other companies undergoing M&A in the future.

In this paper, we developed integrated billing system for multi-language. It is very easy to customize for other language and also It has functions in integrated billing system. Whenever administrator insert UI message data for other language, we can make billing packages for its own country to service integrated billing policy.

The aim of the current work is to investigate the numerical study of a nonlinear Volterra-Fredholm integro-differential equation with initial conditions. Our approximation techniques modified adomian decomposition method (MADM) and variational iteration method (VIM) are based on the product integration methods in conjunction with iterative schemes. The convergence of the proposed methods have been proved. We conclude the paper with numerical examples to illustrate the effectiveness of our methods.

This study examined flow between regions based on the spatial structure of the territory and characterized the flow patterns by analyzing regional networks via transportation connectivity. To accomplish this, transportation connectivity of the entire nation was examined using 2010 national express bus OD data from the Korea Transport Database. After the initial analysis, 2010 car OD data describing networks in seven regions (125 cities and districts), Gangwon-do, Gyeongsangnam-do, Gyeongsangbuk-do, Jeollanam-do, Jeollabuk-do, Chungcheong-do and Seoul, were analyzed to identify transportation connectivity. The results revealed that Korea has strong triangular-belt-shaped transportation connectivity that connects among metropolitan areas in the Jeolla and Gyeongsang areas. Particular zones are set by regional characteristics and functional connectivity for each zone. The results of this study will be useful as a basic material to establish development strategies and customized regional policy development, as well as balanced development.

This paper is a type of business representatives who are responsible for the burden he want to relieve. In addition, to ensure transparency and to contribute to the Elimination of irregularities in cracking down on overcharging to research. In order to avoid duplicate entry of fixed checkpoints of modern equipment was installed in the automatic collection of information inspection. And, if the information is the same information to crack down imposed the Road Fine system linkage system Constrution CALS system to research. Land administration office imposed a fine after confirmation information to crack down on the auditory system, the auditory crackdown imposed fine and proceed to determine the status of your work since. This study was carried out and any future crackdown on overcharging gathering information for the efficient production of surgical intervention for improved accuracy considering that frequency.
