The research tries to find appropriate nations and cities of the international supporting centers according to Korean firms' requests. It also tries to find out proper designs of governance structure and strategic and operational control system of the center. Two methods are used to find out Korean firms' requests. One is the expert interviews and the other is the questionnaire survey. The email survey is sent to 120 firms of IT service, package software, telecom facilities and broadcasting equipment industries. Their opinions in addition to interview results are used as a basis of selecting potential regions for new centers and types of their services. According to survey results, southeast asia is the most preferred region and Indonesia, Vietnam, Thailand, Malaysia and Singapore are selected as potential nations for a location of the center in southeast asia. However, the survey result is not fully agreed with the interviewees' opinions. The interviewees tell that there are not much demand in nations with low purchasing power and low IT industry level. That is, Indonesia and Vietnam are not proper places for the centers.

Recently, blogs have attracted much attention as personal media. The power of blogs as a way to provide valuable resources on Internet is so tremendous because of the high speed of information dissemination and the huge influence of the circulated information on Internet users even when the information itself is not true. Especially, contents on blogs that attract a lot of public attention are sometimes reproduced or magnified in an inappropriate way. In this paper, a method to measure the trust level of contents posted on personal blogs is proposed to reduce the damage of wrong information circulated along with blog networks. Trust variables such as relationship data in SNS are used to measure the comparative trust level of blog contents. The structure of the prototype system is also designed to apply this framework to blogsphere.

Kill Chain is getting attention due to North Korea's recent nuclear test and missile launches and has emerged the need for an early build up. In order to build a materialized kill chain, you should review the unique kill chain to support operations effectively using various sensors and striking weapon system. Especially, you need a suitable network to reduce a reaction time against the enemy attack under joint operations environment etc. Currently there are many communication ways(e.g. data link, voice, video and text message) used in operations through satellite, wired and wireless and so on. Now, this paper contains analysis on various means for target information exchange which are used in the kill chain. And appropriate network of the kill chain for target information transmission is addressed to confirm feasibility of its alternatives, which is developed using AHP(Analytic Hierarchy Process). Finally, this paper is suggesting network and means of its building up for target information transmission of kill chain which can be implemented under the situation of joint battle field.

Today, through developing country's Official Development Assistance (ODA) project, Republic of Korea is giving help in establishing communication networks, furnishing PCs and etc, as a help of information base expansion. And to resolve digital divide between countries, Republic of Korea's IT service group dispatch business has also significantly contributed to enhance information application level of developing countries. The conclusion and suggestion of this study is as follow. It is obvious that utilization of information can be affected by capability improvement of developing country's informatization level. However, developing informatization strategy level and environment in long term wise will cause greater influence than to raise immediate informatization base level. Overall, settlement of long term digital divide seems possible when we elevate developing countries' informatization strategy level and environment.

As ubiquitous computing technologies have advanced rapidly, context awareness technology has been used in the medical part in order to improve patient safety. Nevertheless, as there is no method for managing context awareness information effectively and managing healthcare processes for handling abnormal situations systematically, it is highly required to enhance patient safety in hospital. We propose an innovative system to solve these problems. The proposed system has three main functionalities. Firstly, it enables all situations to be recognized in medical organizations. Secondly, it extracts the meaningful data from data flood by defining data patterns of recognized situations and designing a rule-based system. Lastly, it can manage patients' abnormal situations in process-centric way by integrating the business process management system. It is expected that the proposed system contributes to the improvement of patient safety in u-hospital.

This study is about the suggestion of reduction method for social insurance cost of startup SMEs Based on the study abroad and the current status of Korea we suggest several methods such as direct and indirect support, exemption, deferment/loan. For the economic effect analysis, we derived benefits and costs. Employment, value added, and revenue increasing effects are considered as benefits. Costs are analyzed by each method. In case of exemption, the analysis is impossible. Analysis results show that direct and deferment/loan case have an effect of 563,469 jobs creation, added value of 26.82 trillion wons, and increase in tax revenues about 82.4 billion wons. In case of exemption, There are 105,368 jobs creation, 5.02 trillion wons of added value, and 15.4 billion wons of increase in tax revenues. And for each case, there are costs 9.58 trillion won, 5.42 trillion won, 1.79 trillion won.

Based on the network, recruitment, education services, talent testing and human resources management etc. integrated services are expanded, and efforting to raise the market share of job information site. Job information site is an alternative finding job and recruiting environment, helping job seekers to conduct self-directed researching and applying for a job online. Directly or indirectly influential factors upon value of job information site are on the rise. Not only Korea but also China has already recognized the importance of these influential factors on job information site. However, the effective rate of implementing job information site is relatively lower among Chinese job market than Korea. This study suggests that there are differences of cultural background between Korea and China, and they were at different internet infrastructure, such differences impact on different job seekers.

In this paper we propose a new notion of predictable flags type of authorization for controlling access to XML documents. By using predictable flags, we are able to efficiently detect conflicts between existing authorizations and new authorizations to be added. XML documents have an element-composition hierarchical structure in that a higher level element consists of multiple lower level sub-elements. Many XML documents systems have used the notion of implicit authorization that grants authorizations to an element and the all descendants to avoid the overhead caused by explicitly storing all authorization for each element. When we grant an authorization on an element in the XML documents, the implicit authorization method is inefficient in determining the conflicts since it needs to examine all authorizations on the descendants of that element. In contrast, our mechanism using predictable flags has the advantage of detecting the conflicts immediately at the element where an explicit authorization is to be granted.
